Referring to Fig. 1-Fig. 8, the beauty instrument 100 according to the embodiment of the present application will be described below.

As shown in FIG. 1 , FIG. 2 and FIG. 4 , the beauty instrument 100 according to the embodiment of the present application includes a housing 1 , a lighting assembly 2 , a light-transmitting cold compress 3 , a light-transmitting heat insulation 4 , and a cooling member 5 .

A working chamber 101 is defined inside the casing 1 , and an installation opening 1011 is formed in the working chamber 101 . The lighting assembly 2 is arranged in the working chamber 101. The lighting assembly 2 includes a heat exchange element 21 and a light emitting element 22. A chamber 211 is defined in the heat exchange element 21. The chamber 211 has a first light outlet 211a, and the first light outlet 211 a is disposed corresponding to the installation port 1011 , and the cooling element 5 is disposed on a side of the heat exchange element 21 away from the first light outlet 211 a for transferring cold energy to the heat exchange element 21 . The light-transmitting cold compress 3 is arranged at the installation port 1011 , and the cooling element 5 transmits cold energy to the light-transmitting cold compress 3 through the heat exchange element 21 to cool down the beauty site.

The light-transmitting heat-insulating element 4 is arranged in the chamber 211, and the light-transmitting heat-insulating element 4 is spaced between the light-emitting element 22 and the light-transmitting cold compress 3, and the light-transmitting heat-insulating element 4 divides the chamber 211 into an installation cavity 2111 and a The heat insulation cavity 2112 , the first light outlet 211a is formed in the heat insulation cavity 2112 , and the light-transmitting heat-insulating element 4 is a light-transmitting component to transmit the light emitted by the light-emitting element 22 to the light-transmitting cold compress 3 . The cooling element 5 is disposed on a side of the heat exchanging element 21 away from the first light outlet 211 a for transferring cold energy to the heat exchanging element 21 . It can be understood that the refrigeration element 5 acts as a cold source, and transfers cold energy to the light-transmitting cold compress 3 through the heat exchange element 21,

The light-emitting element 22 is located in the installation cavity 2111 and the installation cavity 2111 is closer to the cooling element 5 than the heat insulation cavity 2112, that is, the installation cavity 2111 and the heat insulation cavity 2112 are arranged sequentially in the direction from the cooling element 5 to the light-transmitting cooling element 3 For example, the installation cavity 2111 is located between the cooling element 5 and the heat insulation cavity 2112, the cooling element 5 cools down the light emitting element 22 in the installation cavity 2111 through the heat exchange element 21, and the heat insulation cavity 2112 is used to block the heat generated by the light emitting element 22. Transfer to the light-transmitting cold pack 3.

Thus, during the laser hair removal process, the cold energy of the cooling element 5 is transferred to the beauty site such as the skin through the heat exchange element 21 and the light-transmitting cold compress element 3, so as to reduce the tingling sensation of the beauty area. It is installed in the installation cavity 2111 defined by the heat exchange element 21 , so the cooling capacity of the cooling element 5 can effectively cool down the light-emitting element 22 , reducing the heat transferred from the light-emitting element 22 to the light-transmitting cold compress 3 .

The light-transmitting and heat-insulating element 4 can not only play the role of light-transmitting, but also can play the role of heat insulation. Not in contact with the light-transmitting cold compress 3, to ensure that the heat-insulating cavity 2112 plays a good heat insulation effect, and to avoid the influence of the light-transmitting heat-insulating member 4 on the temperature of the light-transmitting cold compress 3, thereby further reducing the light-emitting component 22 to the light-transmitting The heat transferred by the cold compress 3 prevents the light-transmitting cold compress 3 from transferring cold energy to the light-transmitting thermal insulation 4 , so that the light-transmitting cold compress 3 can maintain a lower temperature. Since the light-emitting element 22 is closer to the cooling element 5, the cold energy of the cooling element 5 cools down on the light-emitting element 22 and then transfers to the direction of the light-transmitting cold compress 3. The obstruction of the transmission of the cold compress 3 achieves the dual functions of cooling and heat insulation, and reduces the influence of the heat of the light-emitting element 22 on the light-transmitting cold compress 3, so that the light-transmitting cold compress 3 has a better cold compress effect.

According to the beauty instrument 100 of the embodiment of the present application, by setting the light-transmitting heat-insulating element 4 in the chamber 211 and the light-transmitting heat-insulating element 4 is spaced between the light-emitting element 22 and the light-transmitting cold compress element 3, the direction of the cooling element 5 is reversed. The heat transfer element 21 can reduce the temperature of the light-emitting element 22 by transferring cold energy. Under the synergistic effect of heat transfer between the heat exchange part 32 and the heat exchange element 21, the light-transmitting cold compress 3 can be kept at a lower temperature, and the light transmission can be significantly improved. The cold compress effect of the cold pack 3 . Moreover, since the light-emitting element 22 is closer to the cooling element 5, the cold energy of the cooling element 5 is transferred to the direction of the light-transmitting cold compress 3 after cooling the light-emitting element 22, and the heat of the light-emitting element 22 is transferred to the light-emitting element 22 by using the light-transmitting heat insulating element 4 at the same time. The obstruction of the transmission of the light-transmitting cold compress 3 achieves the dual functions of cooling and heat insulation, and reduces the influence of the heat of the light-emitting element 22 on the light-transmitting cold compress 3, so that the light-transmitting cold compress 3 has a better cold compress effect.

Optionally, in the example of FIG. 4 , the distance between the light-emitting element 22 and the cooling element 5 is smaller than the distance between the light-emitting element 22 and the light-transmitting cooling element 3, which is conducive to further improving the cooling effect of the cooling element 5 on the light-emitting element 22 and further reducing The heat transferred from the light-emitting element 22 to the light-transmitting cold compress element 3 .

In some embodiments, as shown in Figure 1, Figure 4 and Figure 5, the light-transmitting cold compress 3 is an integral component, and the light-transmitting cold compress 3 includes a light-transmitting part 31 and a heat exchange part 32, and the light-transmitting part 31 and The first light outlet 211a is oppositely arranged, the heat exchange part 32 avoids the first light outlet 211a, and the heat exchange part 32 cooperates with the end surface of the heat exchange element 21 away from the cooling element 5 to transfer heat, then the heat exchange part 32 and the first light outlet Ports 211a are arranged in a staggered manner.

When the beauty instrument 100 is in use, the light-transmitting cold compress part 3 is used to contact the user's skin, and the light-emitting part 22 is used to emit intense pulsed light. Since the light-transmitting cold compress 3 is separately provided with a heat exchange part 32 that avoids the first light outlet 211a, the structure of the heat exchange part 32 will not be restricted by the first light outlet 211a, so the first light outlet 211a will not be affected. Under the premise of the amount of light emitted by the port 211a, the structural design of the heat exchange part 32 is flexible, which facilitates better assembly between the heat exchange part 32 and the installation port 1011. The light cold compress 3 is reliably assembled with the installation port 1011 through the matching structure of the heat exchange part 32, and the installation performance is improved; at the same time, it is convenient for the heat exchange part 32 to cooperate reliably with the heat exchange part 21. The normal direction is in contact with the heat exchange element 21, so that the heat exchange element 21 can play a certain role of supporting and limiting the heat exchange part 21, which is beneficial for the heat exchange element 21 to limit the heat exchange part 32 to the installation port 1011, that is, the heat exchange part 32 The limit is realized by the heat exchange element 21 and the installation port 1011. When the light-transmitting cold compress 3 contacts the beauty site (such as the user's skin), the light-transmitting cold compress 3 is not easy to shift when subjected to external force, ensuring that the light-transmitting cold compress 3 3 stable installation.

In addition, since the light-transmitting cold compress 3 is not entirely set opposite to the first light outlet 211a, the light-transmitting part 31 can be set correspondingly smaller, and the heat-exchanging part 32 cooperates with the heat-exchanging element 21, such as the heat-exchanging part 21 and the heat-exchanging part 21. 21 contact, so that the heat transfer area between the light-transmitting cold compress 3 and the heat exchange element 21 is larger, and the thickness of the light-transmitting cold compress 3 can be appropriately reduced to improve the heat transfer between the light-transmitting cold compress 3 and the heat exchange element 21 Efficiency is conducive to reducing the cooling time of the light-transmitting cold compress 3, so that the light-transmitting cold compress 3 can quickly cool down and bring better ice compress effect.

It should be noted that “the light-transmitting portion 31 is arranged opposite to/corresponding to the first light outlet 211a” can be understood as, on a reference plane perpendicular to the normal direction of the first light outlet 211a (for example, the up-down direction in FIG. 4 ), The projection profile of the first light outlet 211 a on the reference plane is located within the projection of the light-transmitting portion 31 on the reference plane, so that all the light from the first light-outlet 211 a is emitted through the light-transmitting portion 31 . "The heat exchange part 32 avoids the first light outlet 211a" can be understood as that the projection of the heat exchange part 32 on the reference plane is located outside the projection contour of the first light outlet 211a on the reference plane, that is, the projections of the two do not overlap. The heat portion 32 will not affect the light output from the first light output port 211a.

For example, in the example shown in FIG. 4 , the light-transmitting part 31 is a solid structure. At this time, the light-transmitting part 31 and the heat exchange part 32 can be connected to form an integral solid structure. At this time, all the light from the first light outlet 211a passes through the light-transmitting part 32. The light part 31 is emitted, and a straight line parallel to the thickness direction of the light-transmitting cold compress 3 moves in parallel along the projection contour of the first light outlet 211a on the reference plane to form a reference cylinder, which can divide the light-transmitting cold compress 3 The transparent part 31 and the heat exchange part 32, the transparent part 31 is located inside the reference cylinder, and the heat exchange part 32 is outside the reference cylinder. Or, the light-transmitting part 31 can also be formed as a through hole, that is, a through hole is formed on the light-transmitting cold compress 3, and the through hole penetrates the light-transmitting cold compress 3 along the thickness direction of the light-transmitting cold compress 3, and the through hole is the light-transmitting cold compress 3. At this time, the light-transmitting portion 31 may be defined by the heat exchange portion 21 , and all the light from the first light outlet 211 a is directly emitted through the light-transmitting portion 31 .

For example, as shown in Figure 4, the matching structure provided on the heat exchange part 32 can be a step 321, and the step 321 is arranged around the edge of the heat exchange part 32, and a matching step 1016 is provided on the installation port 1011, and the step 321 and the matching step 1016 correspond to each other. Cooperating can realize the assembly of the heat exchange part 32 and the installation port 1011, improve the reliability of the installation, and the operation is simple and convenient. Wherein, the matching step 1016 can be supported on the bottom of the step 321, so that the width of the installation opening 1011 is smaller than the width of the light-transmitting cold compress 3, so as to prevent the light-transmitting cold compress 3 from detaching from the housing 1 through the installation opening 1011 in the working chamber 101.

It should be noted that, in the description of the present application, "width" refers to the width of the feature in the left-right direction in FIG. 1 .

In some embodiments, as shown in FIG. 1 , the heat exchange element 21 includes two heat conduction parts 2101, and the two heat conduction parts 2101 are arranged opposite to each other to define a chamber 211. One end (for example, the upper end in FIG. 1 ) of the two heat conducting parts 2101 corresponding to the first light outlet 211a (for example, the lower end in FIG. 1 ) is arranged at intervals to jointly define the first light outlet 211a, Each heat conduction part 2101 is respectively in contact with the heat exchange part 32, so that the cold energy of the heat conduction part 2101 is directly transferred to the heat exchange part 32, which is beneficial to reduce the loss of cold energy transfer, and can increase the distance between the heat exchange element 21 and the heat exchange part 32. The heat transfer area improves the heat exchange efficiency, so that the light-transmitting cold compress 3 can cool down more quickly.

For example, in the example of FIG. 1 , the overall configuration of the heat exchange element 21 is U-shaped.

In some embodiments, along the normal direction of the first light outlet 211a (for example, the up-down direction in FIG. 1 and FIG. 4 ), the ratio s2 of the projected area of the light-transmitting part 31 to the projected area of the heat-exchanging part 32 satisfies 0.5≤ s2≤5, so as to ensure that the heat exchange part 32 can better receive the cold energy transferred by the heat exchange element 21 and transfer the cold energy to the transparent part 31 more evenly.

Wherein, the wall surface of the heat dissipation air channel 102 is jointly defined by the surface of the first heat dissipation device 12 and the wall surface of the cavity 1a, and the air flow flows through the heat dissipation air channel 102, and the air flow can cooperate with the participation of the first heat dissipation device 12 to define heat dissipation. The surface of the air duct 102 is in direct contact for heat exchange, and the air flow can also directly contact the wall surface of the cavity 1a that defines the heat dissipation air duct 102, so that the wall surface of the cavity 1a and the surface of the first heat dissipation device 12 can provide heat dissipation. The airflow in the air duct 102 has a certain guiding effect. Therefore, there is no need to additionally arrange structures such as air duct shells, the structure is simple and ingenious, and the cost can be reduced.

According to the beauty instrument 100 of the embodiment of the present application, the wall surface of the heat dissipation air channel 102 is defined by the surface of the first heat dissipation device 12 and the wall surface of the cavity 1a together, on the premise of ensuring the heat dissipation of the first heat dissipation device 12 and the functional components 14 In this way, there is no need to set additional structural components such as complicated air duct shells, which simplifies the structure and reduces costs. More heat exchange air can flow in to improve heat dissipation efficiency. In addition, the number of parts of the beauty instrument 100 is small, which is beneficial to reduce the volume of the beauty instrument 100 and realize the light weight and miniaturization of the beauty instrument 100 .

In some embodiments, the first heat sink 12 is spaced apart from the first air inlet 1012. In this way, on the one hand, it is to prevent the heat of the first heat sink 12 from being directly transferred to the shell 1 and causing damage to the shell 1. It affects its service life.

It can be understood that the distance between the first heat dissipation device 12 and the first air inlet 1012 can be specifically set according to practical applications.

In some embodiments, as shown in FIG. 4 and FIG. 5 , the first heat sink 12 includes a first heat sink 121 , a second heat sink 122 and a first heat transfer connection 123 , the first heat sink 121 is connected to the second heat sink Components 122 are arranged at intervals, the first cooling component 121 is arranged on the outlet side of the first cooling fan 11, and the first cooling component 121 cooperates with the functional component 14 for heat transfer, and the second cooling component 122 is arranged at the inlet of the first cooling fan 11 side, and the second heat dissipation element 122 and the airflow of the heat dissipation air channel 102 conduct heat, and the first heat transfer connecting element 123 is connected between the first heat dissipation element 121 and the second heat dissipation element 122, so that the first heat dissipation element 121 and the second heat dissipation element The two heat sinks 122 cooperate with heat transfer.

Thus, the first heat dissipation device 12 is set to include the first heat dissipation element 121, the second heat dissipation element 122 and the first heat transfer connecting element 123, and the airflow in the heat dissipation air channel 102 can flow through the second heat dissipation element 122, the second heat dissipation element 122, and the second heat dissipation element in sequence.

The first heat sink 121 cooperates with the functional component 14 to take away the heat of the functional component 14 in time. The second heat sink 122 is located on the first cooling fan 11 The inlet side of the inlet side can be kept in a lower temperature state. Under the action of the first heat transfer connecting piece 123, the second heat sink 122 and the first heat sink 121 perform heat exchange to reduce the heat of the functional component 14. Under the action of the first cooling fan 11 , the heat of the functional components 14 can also be discharged quickly, so as to ensure the normal use of the beauty instrument 100 .

Optionally, the first heat sink 121 is an aluminum alloy or copper alloy; the second heat sink is 122 an aluminum alloy or copper alloy.

In some embodiments, as shown in FIG. 4 , the first heat dissipation fan 11 is an axial flow fan, so that the wind can go straight in and out along the axial direction of the axial flow fan, which is conducive to further improving the heat dissipation efficiency; wherein the first heat dissipation fan 11 The two axial ends of the radiating element 121 and the second radiating element 122 respectively, at this time, the first heat radiating fan 11 can be arranged between the first radiating element 121 and the second radiating element 122, so as to facilitate the realization of the first heat radiating device 12 And the rationalized layout of the first cooling fan 11 facilitates making the structure more compact and reducing the volume of the beauty instrument 100 .

In some embodiments, the first cooling fan 11 includes a motor. When the first air inlet 1011 is used as the air inlet and the first air outlet 1015 is used as the air outlet, the motor is arranged on the side close to the first air inlet 1011, and the first air inlet 1015 is used as the air outlet. The temperature of the tuyere 1015 is low, which can prevent the high temperature environment from affecting the service life of the motor.

In some embodiments, as shown in FIG. 4 , the axial ends of the first heat dissipation fan 11 abut against the walls of the second heat dissipation member 122 and the heat dissipation air channel 102 respectively, so as to facilitate the reliable positioning of the first heat dissipation fan 11 .

In some embodiments, as shown in FIG. 4 and FIG. 1 , the first cooling fan 11 includes a fan case 111 and a fan 112 , and the fan case 111 is arranged around the outside of the fan 112 to define a guide air duct 11a to guide the wind The channel 11 a is used to guide the airflow to the first heat sink 12 . The guide air duct 11a can play a guiding role, so that the wind blown by the fan 112 can flow along the air duct wall of the guide air duct 11a (see Figure 4, the arrow in the figure is the flow direction of the air flow), reducing the disorderly flow of wind The air flow path is shorter, the heat exchange is faster, and the heat dissipation effect is better.

In some embodiments, as shown in FIG. 4 and FIG. 5 , the first heat sink 12 includes a first heat sink 121 , a second heat sink 122 and a first heat transfer connection 123 , the first heat sink 121 is connected to the second heat sink Components 122 are arranged at intervals, the first cooling component 121 is arranged on the outlet side of the first cooling fan 11, and the first cooling component 121 cooperates with the functional component 14 for heat transfer, and the second cooling component 122 is arranged at the inlet of the first cooling fan 11 side, and the second heat dissipation element 122 and the airflow of the heat dissipation air channel 102 conduct heat, and the first heat transfer connecting element 123 is connected between the first heat dissipation element 121 and the second heat dissipation element 122, so that the first heat dissipation element 121 and the second heat dissipation element The two heat sinks 122 cooperate with heat transfer. Wherein, on the cross-section of the air guiding channel 11a, the projection of the first heat transfer connecting member 123 is set outside the outer contour of the guiding air channel 11a, that is to say, the first heat transferring connecting member 123 will not block the air guiding channel 11a. The air flow in the air induction channel 11 a is convenient to further ensure the air flux of the heat dissipation air channel 102 on the premise of ensuring effective heat exchange between the air flow and the first heat dissipation device 12 .

For example, in the example shown in FIG. 4 , the guide air channel 11 a is used to guide the airflow to the first heat sink 121 . Of course, the guiding air channel 11a can also guide the airflow to the first heat sink 121 and the second heat sink 122 ; but it is not limited thereto.

In some embodiments, as shown in FIG. 4 , the first cooling fan 11 is an axial flow fan, one axial end of the first cooling fan 11 faces the first air inlet 1012, and the other axial end of the first cooling fan 11 faces the functional Assembly 14 to facilitate shortening the airflow path. Wherein, the first air outlet 1015 is arranged on the peripheral side of the functional component 14, then the first air outlet 1015 can be arranged around the functional component 14 along the circumferential direction of the first heat dissipation fan 11, so as to facilitate the dispersed discharge of air with a higher temperature, and It is beneficial to reduce the exhaust air temperature of the beauty instrument 100 .

It can be understood that the first air outlet 1015 is arranged around the functional component 14 along the circumferential direction of the first cooling fan 11, including that the first air outlet 1015 is arranged around the functional component 14 along the circumferential direction of the first cooling fan 11, or The first air outlet 1015 surrounds the functional component 14 less than a full circle along the circumferential direction of the first cooling fan 11 . For example, in the examples of Fig. 2, Fig. 4 and Fig. 1, the first air outlet 1015 is arranged on the opposite sides (for example, the left and right sides in Fig. The first air outlet 1015 surrounds the functional component 14 less than a full circle along the circumferential direction of the first cooling fan 11 .

In some embodiments, as shown in FIGS. 4-1 , the functional component 14 includes a cooling component 5 and a lighting component 2, the lighting component 2 includes a light emitting component 22, the cooling component 5 is arranged in the cavity 1a, and the cooling component 5 Participate in dividing the cavity 1a into the cooling air channel 102 and the working cavity 101, then the cooling element 5 can participate in separating the cooling air channel 102 and the working cavity 101, so as to prevent the hot air in the cooling air channel 102 from flowing into the working cavity 101 , affect the cooling effect of the refrigeration unit 5, and facilitate the avoidance of hot air in the cooling air duct 102 from blowing to the cold end of the refrigeration unit 5, causing condensation, leakage, etc.; the lighting assembly 2 is located in the working chamber 101, and the Part 5 is used to transfer cold energy to the lighting assembly 2, so as to reduce the tingling sensation of the beauty instrument 100 in the process of beautifying the parts to be treated. For example, when the beauty instrument 100 is a hair removal device, the setting of the cooling part 5 can reduce the In the process of depilating the beauty area, the tingling sensation produced by the depilator acting on the skin. Thus, the lighting component 2 can emit intense pulsed light to provide the energy required for cosmetic hair removal, while the cooling element 5 can provide a cold source to reduce the tingling sensation on the user's skin.

For example, the cold end of the cooling element 5 transfers cold energy to the lighting assembly 2, and the hot end of the cooling element 5 exchanges heat with the airflow in the heat dissipation air duct 102. The hot end of the component 5 and the wall surface of the cavity 1 a together define a cooling air channel 102 . The hot end of the cooling element 5 can be attached to the first heat sink 12, for example, the hot end of the cooling element 5 is set in contact with the first heat sink 121, so that the cooling element 5 transfers heat to the first heat sink 12, through the second A heat dissipation device 12 dissipates heat to the hot end of the cooling element 5 to prolong the life of the cooling element 5 .

It should be noted that "the cooling element 5 participates in separating the heat dissipation air duct 102 from the working chamber 101" may mean that only the cooling element 5 can be used to separate the heat dissipation air duct 102 from the working chamber 101, or it may refer to The refrigerating element 5 and other components are used to separate the cooling air passage 102 from the working chamber 101 . Wherein, "the heat dissipation air duct 102 is set apart from the working chamber 101" may mean that the cooling element 5 participates in completely separating the heat dissipation air duct 102 from the working chamber 101, and at this time, the heat dissipation air duct 102 is completely disconnected from the working chamber 101 , there is no air flow, so as to effectively isolate the heat transfer between the cooling air duct 102 and the working chamber 101, it can also mean that the cooling element 5 participates in separating the cooling air duct 102 from the working chamber 101. At this time, the cooling air duct 102 and the working chamber 101 The working chambers 101 are separated at some positions and connected at some positions, it is only necessary to ensure that the hot air in the cooling air duct 102 will not flow into the working chamber 101 .

Optionally, when the first heat dissipation device 12 includes the first heat dissipation element 121 and the second heat dissipation element 122, in the circumferential direction of the first heat dissipation fan 11, the outer peripheral wall of the hot end of the cooling element 5 and the outer periphery of the first heat dissipation element 121 The wall is exposed in the heat dissipation air duct 102, that is to say, the outer peripheral wall of the hot end of the cooling element 5 and the outer peripheral wall of the first heat dissipation element 121 can directly contact with the airflow in the heat dissipation air duct 102 for heat exchange, which is beneficial to further Improve cooling efficiency.

In some embodiments, as shown in FIG. 4 , FIG. 5 , and FIG. 1 , the functional component 14 further includes a partition 10, the partition 10 is arranged in the cavity 1a, and the partition 10 is wound around the cold end of the cooling element 5, Then the partition 10 can be arranged at the outer edge of the cold end of the refrigeration element 5, for example, the partition 10 is arranged around the cold end of the refrigeration element 5 to form an open ring or a closed ring, and of course the partition 10 can also be formed into other shapes, such as When the refrigeration element 5 is formed into a square structure, the partition 10 can be formed into a strip structure and cooperate with at least one side of the four side edges of the cold end of the refrigeration element 5; the partition 10 is in contact with the wall of the cavity 1a, so as to The cold end of the cooling element 5 is separated from the heat dissipation air duct 102 to prevent the hot air in the heat dissipation air duct 102 from transferring heat to the cold end of the refrigeration element 5, and at the same time, the hot end of the refrigeration element 5 can be separated from the working chamber 101. The heat transfer from the hot end of the cooling element 5 to the working chamber 101 is prevented, so as to ensure the cooling efficiency of the cold end of the cooling element 5 to the lighting assembly 2 and reduce the leakage of cold energy.

Because the temperature of the airflow in the heat dissipation air duct 102 is relatively high, and the temperature of the cold end of the cooling element 5 is relatively low, by setting the separator 10, it can be effectively prevented that the hot air in the heat dissipation air duct 102 rushes into the cold end of the refrigeration element 5 and the cooling element 5, that is to prevent the airflow of the cooling air duct 102 from affecting the cooling effect of the cold end of the cooling element 5. Secondly, the partition 10 surrounds the cold end of the cooling element 5 so that the partition 10 covers at least part of the cold end of the cooling element 5 to avoid loss of cooling capacity.

It should be noted that the "open ring" described herein refers to: a ring with an opening (that is, a non-closed ring), wherein "ring" is understood in a broad sense, that is, it is not limited to "circular ring", for example, it can also be are "polygon rings" and so on.

At least part of the airflow is guided to the first air outlet 1015, and the first air outlet 1015 can be used as an air outlet at this time. Among them, the guide surface 10a is used to improve the heat dissipation efficiency. When the first heat dissipation fan 11 dissipates heat to the first heat dissipation device 12, the heat in the casing 1 can be quickly transferred to the casing 1 through the flow guide surface 10a, and the flow guide The surface 10a does not obstruct the flow of air, and then it is transmitted to the outside of the housing 1 through the first air outlet 1015 on the housing 1 to achieve the purpose of heat dissipation and improve the heat dissipation efficiency.

For example, in the example of FIG. 4 , the opposite sides of the partition 10 (for example, the left and right sides in FIG. 4 ) have guide surfaces 10a, and the outer ends of each guide surface 10a extend to the first air outlet 1015. so that the partition 10 will not block the airflow at the first air outlet 1015, which is convenient to further ensure the smooth exhaust of the beauty instrument 100 with less air exhaust resistance.

In some embodiments, as shown in FIG. 4 and FIG. 1 , the lighting assembly 2 further includes a heat exchange element 21 and a light-transmitting heat-insulating element 4 , a cavity 211 is defined in the heat-exchanging element 21 , and the light-transmitting heat-insulating element 4 It is installed in the chamber 211, and the light-transmitting heat insulating member 4 divides the chamber 211 into an installation chamber 2111 and a heat insulation chamber 2112. The light emitting element 22 is arranged in the installation chamber 2111, and the heat insulation chamber 2112 is formed with a first light outlet 211a to emit light. Part 22 is used as a light source to provide the intense pulsed light required for beauty treatment. The light from the light-emitting part 22 passes through the light-transmitting heat-insulating part 4 and shoots to the first light outlet 211a and the installation port 1011 in sequence, that is, the light from the light-emitting part 22 passes through the light-transmitting The heat insulating element 4 first shoots to the first light outlet 211a, then to the installation port 1011, and finally passes through the installation port 1011 to exit. The chamber 211 is divided into an installation chamber 2111 and a heat insulation chamber 2112 by the light-transmitting and heat-insulating member 4, and the light-emitting member 22 is set in the installation chamber 2111, which can gather light in the installation chamber 2111, avoiding the loss of light energy, and improving the light energy Utilization rate; secondly, the light-transmitting heat insulating element 4 can play the role of isolating heat transfer, weakening the temperature of light, ensuring that the heat-insulating cavity 2112 plays a good heat-insulating effect, and is beneficial to avoid the tingling sensation of light on the user's skin.

In some embodiments, the light-transmitting heat-insulating element 4 is a light filter, which is used to filter out light of a suitable wavelength.

In some embodiments, as shown in FIG. 4 , the width of the installation cavity 2111 is smaller than the width of the heat insulation cavity 2112, so that there is a step between the installation cavity 2111 and the heat insulation cavity 2112, and the back of the light-transmitting heat-insulating member 4 is transparent. One side of the light cold compress 3 is abutted against the step portion. The step portion can provide an installation position, facilitate the installation and positioning of the light-transmitting heat-insulating element 4 , and ensure that the light-transmitting heat-insulating element 4 is not easily displaced in the chamber 211 .

For example, in the example of Fig. 4, there is a step at the edge of the light-transmitting cold compress 3, and the step is arranged around the edge of the light-transmitting cold compress 3, and a matching step is provided on the installation port 1011, and the matching step is supported at the bottom of the step to avoid The light-transmitting cold compress 3 is detached downwards to the outside of the housing 1 through the installation opening 1011; the part of the first bracket 6 located in the heat-insulating cavity 2112 is supported between the light-transmitting heat-insulating element 4 and the light-transmitting cold compress 3 , because the shell The body 1 restricts the downward movement of the light-transmitting cold compress 3 , then the light-transmitting cold compress 3 can restrict the downward movement of the inner bracket part 61 , and the upper end of the light-transmitting thermal insulation 4 stops against the step part, and the step part can pass through the light-transmitting The heat insulating element 4 restricts the upward movement of the inner support part 61 , thereby realizing the stable installation of the light-transmitting cold compress 3 , the light-transmitting heat insulating element 4 and the first support 6 .

In the description of the present application, "width" refers to the width of the feature in the left-right direction in FIGS. 2-4 .

In some embodiments, as shown in Fig. 4 and Fig. 1, the beauty instrument 100 further includes a first reflective member 7, the first reflective member 7 is arranged in the heat insulation cavity 2112, and the first reflective member 7 is arranged along the first light outlet. The edge of 211a extends along the extension direction. When the light passes through the heat-insulating cavity 2112, the first reflector 7 can reflect the light and converge it at the first light outlet 211a, reducing light loss and improving light energy utilization.

Optionally, the first reflector 7 is a closed annular reflector, and the first reflector 7 can extend around the circumference of the normal line of the first light outlet 211 a to surround the inner wall of the heat insulation cavity 2112 .

In some embodiments, as shown in FIG. 4 and FIG. 1 , the beauty instrument 100 further includes a second reflective member 8 , and the second reflective member 8 is arranged in the installation cavity 2111 , so that the second reflective member 8 can reflect the The light is converged at the light outlet of the installation cavity 2111, so that the light emitted by the light-emitting element 22 is directed to the light-transmitting and heat-insulating element 4, thereby reducing light loss and improving the utilization rate of light energy; wherein, the second reflective element 8 is attached to the installation cavity The wall surface of 2111 is convenient to improve the heat transfer effect between the heat exchange element 21 and the second reflective element 8 , thereby further improving the cooling effect of the cooling element 5 on the light emitting element 22 .

Optionally, as shown in FIG. 1 , the second reflector 8 is configured as an arc-shaped reflector, and the arc-shaped reflector is covered on a side of the light-emitting element 22 facing away from the light-transmitting and heat-insulating element 4 .

In some embodiments, the heat insulation cavity 2112 has a light incident area, and the installation cavity 2111 has a second light exit area, and the light in the second light exit area passes through the light-transmitting heat insulating member 4 and is emitted to the light entrance area. The width of the second light exit area is Less than or equal to the width of the incident area. As shown in Figure 1, the upper opening of the heat insulation cavity 2112 forms a light incident area, and the lower opening of the installation cavity 2111 forms a second light output area, and the width of the second light output area is less than or equal to the width of the light input area. The light area completely receives the light from the second light output area, avoiding the wall of the heat insulation cavity 2112 from blocking the light, and ensuring the light output of the lighting assembly 2 .

For example, when the beauty instrument 100 includes the first reflective member 7 and the second reflective member 8, the light incident area of the heat insulation cavity 2112 can be understood as the opening defined by the first reflective member 7, such as the upper side opening of the first reflective member 7. The second light exit area of the installation cavity 2111 can be understood as the opening defined by the second reflective member 8, such as the lower side opening of the second reflective member 8, and the width of the opening defined by the second reflective member 8 is less than or equal to The width of the opening defined by the first reflective member 7 .

In some embodiments, as shown in Fig. 4 and Fig. 1, the beauty instrument 100 also includes a light-transmitting cold compress 3, and the light-transmitting cold compress 3 is arranged at the installation port 1011. The beauty instrument 100 also includes a first bracket 6, a first At least part of the bracket 6 is set in the heat insulation cavity 2112, and the part of the first bracket 6 set in the heat insulation cavity 2112 is supported between the light-transmitting heat-insulating member 4 and the light-transmitting cold compress 3, so that the first support 6, An airtight cavity is jointly defined between the light-transmitting heat insulating element 4 and the light-transmitting cooling element 3 .

Obviously, the first bracket 6 can play a supporting role, effectively ensuring that the light-transmitting heat-insulating element 4 and the light-transmitting cold compress 3 do not directly contact each other, so that the light-transmitting heat-insulating element 4 is arranged at intervals between the light-emitting element 22 and the light-transmitting cold compress. Between the parts 3, reduce the influence of the light-transmitting heat insulation part 4 on the temperature of the light-transmitting cold compress 3, thereby further reducing the heat transmitted from the light-emitting part 22 to the light-transmitting cold compress 3, and avoiding the light-transmitting cold compress 3 The cold energy is transferred to the light-transmitting heat insulation element 4, so that the light-transmitting cold compress element 3 can maintain a lower temperature and improve the cold compress effect. There is an appropriate distance between the pieces 3 .

Wherein, the airtight cavity defined between the first bracket 6, the light-transmitting heat-insulating element 4 and the light-transmitting cold compressing element 3, on the one hand, makes the light-transmitting heat-insulating element 4 and the light-transmitting cold compressing element 3 have a certain spacing distance, so as to To ensure the heat insulation effect of the heat insulation cavity 2112, on the other hand, because the light from the light-emitting element 22 reaches the light-transmitting cold compress 3 through the light-transmitting heat-insulating element 4, the airtight cavity can ensure that there is very little moisture inside and condensation is not easy to occur. Avoid affecting light transmission and electric leakage, so as to effectively ensure the normal operation of the beauty instrument 100 .

Optionally, in the example of FIG. 4 , the wall surface of the heat insulation cavity 2112 is spaced apart from the part of the first bracket 6 inside the heat insulation cavity 2112 to jointly define a heat insulation layer. That is to say, the first support 6 is not in contact with the heat exchange element 21, and since the heat exchange element 21 is used to transfer the cold energy of the refrigeration element 5 to the light-transmitting cold pack 3, the wall surface of the heat insulation cavity 2112 is spaced from the first support 6 The setting can greatly reduce the cold energy transferred from the heat exchange element 21 to the first bracket 6, so that more cold energy absorbed by the heat exchange element 21 can be transferred to the light-transmitting cold compress 3, ensuring that the light-transmitting cold compress 3 cooling effect.

Optionally, the heat insulation layer can be an air layer. At this time, there is no need to set other components between the wall surface of the heat insulation chamber 2112 and the inner bracket part 61, which facilitates the simplification of the structure of the beauty instrument 100; or the heat insulation layer can also be an insulation layer. Thermal material parts, such as heat insulation layer is a mica sheet, that is, the heat insulating material part is arranged between the wall surface of the heat insulation cavity 2112 and the inner support part 61 to separate the inner support part 61 from the wall surface of the heat insulation cavity 2112, to lift The heat insulation effect further reduces the cold energy transferred from the heat exchange element 21 to the inner frame part 61 .

In some embodiments, the light-transmitting cold compress 3 and the heat exchange element 21 conduct heat transfer, the heat exchange element 21 conducts heat transfer with the cold end of the cooling element 5 , and the cooling capacity of the cooling element 5 is transferred to the light-transmitting element through the heat exchange element 21 Cold compress 3, when the light-transmitting cold compress 3 contacts the user's human body to be treated, for example, the human body to be treated is the skin of a certain area, the light-transmitting cold compress 3 can play a cold compress effect, and relieve the stinging pain caused by light on the skin feel.

For example, in the examples shown in Figures 4 and 5, the light-transmitting cold compress 3 includes a light-transmitting part and a heat transfer part, the light-transmitting part is opposite to the first light outlet 211a, the heat transfer part avoids the first light outlet 211a, and heat transfer The heat transfer part cooperates with the heat exchange element 21 to transfer heat. Obviously, the heat transfer part does not block the first light outlet 211a, and the heat transfer part and the first light outlet 211a are alternately arranged.

Since the light-transmitting cold pack 3 is separately provided with a heat transfer part that avoids the first light outlet 211a, the structural setting of the heat transfer part will not be limited by the first light outlet 211a, so the premise of not affecting the light output of the first light outlet 211a Next, the structural design of the heat transfer part is flexible, which facilitates better assembly between the heat transfer part and the installation port 1011. For example, it is convenient to arrange a matching structure on the heat transfer part, which is conducive to the light-transmitting cold compress 3 passing through the heat transfer part. The matching structure and the installation port 1011 are reliably assembled to improve the installation performance; at the same time, it is convenient for the heat exchange part to cooperate reliably with the heat exchange element 21. For example, the heat exchange part can contact the heat exchange element 21 in the normal direction of the first light outlet 211a, so that the heat exchange The part 21 can play a certain role of supporting and limiting the heat exchange part, which is beneficial for the heat exchange part 21 to limit the heat exchange part to the installation port 1011, that is, the heat exchange part realizes the limit through the heat exchange part 21 and the installation port 1011, when When the light-transmitting cold compress 3 contacts the beauty site (such as the user's skin), the light-transmitting cold compress 3 is not easy to shift when subjected to an external force, ensuring stable installation of the light-transmitting cold compress 3 .

In addition, since the light-transmitting cold compress 3 is not entirely set opposite to the first light outlet 211a, the light-transmitting part can be set correspondingly smaller, and the heat-exchanging part cooperates with the heat-exchanging element 21, for example, the heat-exchanging part and the heat-exchanging element 21 are in contact. , so that the heat transfer area of the light-transmitting cold compress 3 and the heat-exchanging element 21 is relatively large, and the thickness of the light-transmitting cold compress 3 can be appropriately reduced to improve the heat transfer efficiency of the light-transmitting cold compress 3 and the heat-exchanging element 21. It is beneficial to shorten the cooling time of the light-transmitting cold compress 3, so that the light-transmitting cold compress 3 can cool down quickly, and bring better ice compress effect.

It should be noted that "the light-transmitting part is arranged opposite/corresponding to the first light outlet 211a" can be understood as, on a reference plane perpendicular to the normal direction of the first light outlet 211a (for example, the up-down direction in FIG. 4 ), the second The projection profile of the first light outlet 211a on the reference plane is located within the projection profile of the light-transmitting portion on the reference plane, and all light from the first light-exit 211a is emitted through the light-transmitting portion. "The heat exchange part avoids the first light outlet 211a" can be understood as that the projection of the heat exchange part 3 on the reference plane is outside the projection contour of the first light outlet 211a on the reference plane, that is, the projections of the two do not overlap, and the heat exchange The portion will not affect the light output from the first light output port 211a.

Optionally, in the example shown in FIG. 4 , the light-transmitting part is a solid structure. At this time, the light-transmitting part and the heat exchange part can be connected to form an integral solid structure. At this time, all light from the first light outlet 211a passes through the light-transmitting For example, a straight line parallel to the thickness direction of the light-transmitting cold compress 3 moves in parallel along the projection contour of the first light outlet 211a on the reference plane to form a reference cylinder, which can divide the light-transmitting cold compress 3 into light-transmitting The light-transmitting part is located inside the reference cylinder, and the heat exchange part is outside the reference cylinder. Or, the light-transmitting part can also be formed as a through hole, that is, a through hole is formed on the light-transmitting cold compress 3, and the through hole runs through the light-transmitting cold compress 3 along the thickness direction of the light-transmitting cold compress 3, and the through hole is the light-transmitting part , at this time, the light-transmitting part may be defined by the heat-exchanging part, and all light from the first light outlet 211a is directly emitted through the light-transmitting part.

In some embodiments, the light-transmitting cold applicator 3 is made of sapphire material or glass (such as common glass).

In some embodiments, as shown in FIG. 1 , the luminous element 22 includes a lamp tube 221 , and the two ends of the installation cavity 2111 along the axial direction of the lamp tube 221 respectively pass through the heat exchange element 21 , and the beauty instrument 100 also includes a second bracket 9 , The second bracket 9 is arranged outside the installation cavity 2111, and the second bracket 9 is fixedly connected to the axial ends of the lamp tube 221 respectively, that is to say, setting the second bracket 9 outside the installation cavity 2111 will not occupy the installation cavity 2111 The space will not block the light of the lamp tube 221, reducing light loss. At the same time, the design of the second bracket 9 is not easily restricted by the installation cavity 2111, and it is also convenient for the second bracket 9 to be connected to other components such as the housing 1.

Wherein, the thermal conductivity coefficient of the second support 9 is smaller than the thermal conductivity coefficient of the heat exchange element 21, then the heat of the lamp tube 221 is not easy to transfer outwards through the second support 9, preventing the lamp tube 221 from directly transferring heat to the heat exchange element 21, and at the same time The heat transferred from the lamp tube 221 to other components through the second bracket 9 can be reduced.

Optionally, as shown in FIG. 2 , the beauty instrument 100 includes a first bracket 6 , and the part of the first bracket 6 disposed in the heat insulation cavity 2112 is supported between the light-transmitting heat-insulating element 4 and the light-transmitting cold compress element 3 , The second bracket 9 is connected to the first bracket 6, so that the bracket composed of the first bracket 6 and the second bracket 9 can realize "one thing with multiple functions", so as to simplify the process, reduce the cost, and realize the compact structure design.

Of course, the setting of the second bracket 9 is not limited to this; independently provided brackets, the second bracket 9 and the first bracket 6 are assembled respectively.

In some embodiments, as shown in FIG. 4, the beauty instrument 100 also includes a light-transmitting cold compress 3, which is arranged at the installation port 1011, and the functional component 14 includes a cooling component 5 and a lighting component 2.

During the beautification process, the light-transmitting cold compress 3 transfers the cold energy to the skin, reducing the tingling sensation of the skin and playing a cold compress effect; the lighting component 2 emits The light from the light-transmitting cold compress 3 penetrates, then in the cosmetic process, the light emitted by the lighting assembly 2 can pass through the light-transmitting cold compress 3 and shoot to the human body to be treated, so as to realize the cosmetic function.

Wherein, the included angle between the air outlet direction of the first air outlet 1015 and the normal direction of the working surface of the light-transmitting cold compress 3 is α, and α≥15°. When the air outlet 1015 is discharged, the air with a higher temperature at the first air outlet 1015 can be blown out in a direction away from the part of the human body to be beautified, so as to effectively prevent the air with a higher temperature from blowing to the part of the user's human body to be beautified and affect the user's experience At the same time, the deflection of the air outlet direction of the first air outlet 1015 relative to the air inlet direction of the first air inlet 1012 is small, which will not make the path of the cooling air duct 102 complicated. For example, the included angle α may be 15°, or 20°, or 25°, or 90°, etc.

Compared with the second heat sink 122, the first heat sink 121 is arranged close to the hot end surface 0311 of the cooling element 5, and the hot end surface 0311 of the cooling element 5 transfers heat to the first heat sink 121, and then the first heat sink 121 The thermal connector 123 then transfers the heat on the first heat dissipation element 121 to the second heat dissipation element 122. Because the second heat dissipation element 122 is arranged in the heat dissipation air duct 102, the airflow in the heat dissipation air duct 102 is in the first heat dissipation fan 11. During the process of circulation under the action of the heat sink, the heat on the second heat sink 122 can be transferred to the first air outlet 1015 and then transferred to the outside of the housing 1 through the first air outlet 1015 to achieve the purpose of heat dissipation.

Both the functional components 14 and the first heat dissipation device 12 are arranged in the casing 1, on the one hand, it is ensured that the functional components 14 and the first heat dissipation device 12 will not occupy the space outside the casing 1, so as to ensure that the beauty instrument 100 forms an integral structure , easy to store and carry; on the other hand, the housing 1 can protect the functional components 14 and the first cooling device 12. During the use of the beauty instrument 100, external hard objects will not affect the functional components 14 and the first heat sink. The heat dissipation device 12 causes damage and prolongs the service life of the functional components 14 and the first heat dissipation device 12, thereby reducing the cost of using the beauty instrument 100 and improving user experience.

Because the lighting assembly 2 generates more heat during the process of emitting light, the application provides a cooling element 5 for transferring cold energy to the lighting assembly 2 to reduce the temperature of the lighting assembly 2 during work. On the one hand, it prolongs the service life of the lighting component 2 , and on the other hand, it prevents the lighting component 2 from transferring heat to other components, causing the user to feel burning pain when using the beauty instrument 100 , thereby improving user experience.

As we all know, during the working process of the refrigeration unit 5, if you want to ensure that the refrigeration unit 5 has a good cooling effect, you must ensure that the heat generated by the refrigeration unit 5 in the cooling process can be dissipated in time. Therefore, the application sets the cooling unit 02 The heat dissipation component 02 is used to dissipate heat from the cooling component 5 , so as to ensure that the cooling component 5 has a better cooling effect, so as to effectively transfer cold energy to the lighting assembly 2 .

By setting the first heat dissipation element 121, the second heat dissipation element 122 and the first heat transfer connecting element 123 that cooperate with each other, and the first heat dissipation element 121 cooperates with the cooling element 5 to transfer heat, the cooling element 5 transfers heat to the lighting assembly 2 During the process of heat dissipation, the heat generated by the cooling element 5 will be transferred to the first heat sink 121, because the first heat sink 121 and the second heat sink 122 cooperate to transfer heat through the first heat transfer connecting piece 123, therefore, the first heat dissipation The heat on the component 121 will be transferred to the second cooling component 122 through the first heat transfer connecting component 123 to reduce the temperature of the cooling component 5 faster and better to achieve the purpose of cooling the cooling component 5 .

In the related art, only one cooling element is provided to cooperate with the cooling element 5 for heat transfer. Due to the space limitation near the cooling element 5, it is difficult to make the volume of the cooling element large, and the heat dissipation performance is not ideal. In the first heat dissipation device 12 of the present application, one heat dissipation element, that is, the first heat dissipation element 121 is set to cooperate with the cooling element 5 for heat transfer, and the other heat dissipation element, that is, the second heat dissipation element 122 can be connected with the first heat dissipation element 121. Spaced apart, it may not be limited by the space near the cooling element 5, so that the first heat dissipation device 12 may contain a larger number of heat dissipation elements, so that the heat dissipation capability is stronger and the heat dissipation performance is better.

Moreover, compared with the related art, the beauty instrument 100 of the present application is spaced apart from the first heat sink 121 and the second heat sink 122 to form a heat dissipation cavity between the first heat sink 121 and the second heat sink 122 023, so that the first heat dissipation device 12 can use the heat dissipation cavity 023 to circulate more airflow, so as to use the heat dissipation cavity 023 to increase the air flow rate for heat exchange, prolong the residence time of the airflow in the first heat dissipation device 12, and improve heat transfer efficiency.

It can be known from the above structure that the beauty instrument 100 of the embodiment of the present application, by forming the first air inlet 1012 and the first air outlet 1015 on the housing 1, cooperates with the first cooling fan 11 to facilitate the circulation of the air inside the housing 1 , so as to realize the heat exchange between the air inside the casing 1 and the normal-temperature air outside, so as to achieve the purpose of dissipating heat from the beauty instrument 100 . That is, by setting the first heat dissipation fan 11, the first heat dissipation fan 11 cooperates with the first air inlet 1012 and the first air outlet 1015 formed on the housing 1, when the first heat dissipation fan 11 is working, the first heat dissipation fan 11 It can speed up the circulation of the air flow. At this time, the outside normal temperature air can enter the housing 1 through the first air inlet 1012, and then exchange heat with the heat in the housing 1, and then the heat is discharged from the first air outlet 1015 to ensure the smooth flow of heat. Stable discharge and improved heat dissipation efficiency.

Because the second heat sink 122 is arranged on the airflow path from the first air inlet 1012 to the first air outlet 1015, when the first heat dissipation fan 11 speeds up the air flow, the heat from the first heat sink 121 can be transferred to the second heat sink. The heat on the cooling element 122 is taken away and exported to the outside of the casing 1 through the first air outlet 1015 , reducing the heat inside the casing 1 and achieving the purpose of cooling the inside of the casing 1 . It can be seen that, in this application, the cooperation of the first heat dissipation fan 11 and the first heat dissipation device 12 realizes heat dissipation twice, which greatly improves the heat dissipation effect of the beauty instrument 100 and prolongs the service life of the beauty instrument 100 .

It should be noted that, because the second heat sink 122 is located upstream of the heat dissipation cavity 023, the second heat sink 122 and the heat dissipation cavity 023 are both arranged on the airflow path from the first air inlet 1012 to the first air outlet 1015, thus When the first heat dissipation fan 11 accelerates the airflow, the heat taken away from the second heat dissipation element 122 will flow through the heat dissipation cavity 023, and the heat dissipation cavity 023 can prolong the residence time of heat in the airflow path to improve heat dissipation The heat exchange efficiency of the airflow improves the heat dissipation effect.

It can be understood that compared with the related art, the beauty instrument 100 of the present application can dissipate the heat in the casing 1 multiple times by setting the first heat dissipation fan 11 and the first heat dissipation device 12 that cooperate with each other, and utilize the heat dissipation capacity Cavity 023 prolongs the residence time of the airflow in the first cooling device 12 and the housing 1, improves the heat dissipation effect, reduces the temperature inside the housing 1, prolongs the service life of the beauty instrument 100, and avoids the The risk of users being scalded improves user experience.

It should be noted that the materials of the first heat sink 121 and the second heat sink 122 are not limited, for example, they may be aluminum alloy parts or copper alloy parts.

Optionally, as shown in FIG. 16 , the lighting assembly 2 includes a light emitting element 22 and a heat exchange element 21, the light emitting element 22 is suitable for emitting light of a specific wavelength, for example: the light emitting element 22 is suitable for emitting light of a wavelength of 420-1200nm, Of course, the luminous element 22 is not limited to only emitting light with a wavelength of 420-1200nm, and the emitted wavelength can be selected according to actual use requirements. The light emitted by the luminous element 22 is emitted through the light-emitting area and acts on the user's skin to achieve beauty. the goal of. The heat exchange element 21 cooperates with the cooling element 5 to transfer cold energy to the light-emitting element 22 to cool down the light-emitting element 22. When prolonging the service life of the light-emitting element 22, it also prevents the light-emitting element 22 from blowing to other components. Heat transfer, thereby reducing the tingling sensation of the user during beauty treatment and improving the user experience.

In some examples, the light emitting element 22 may specifically be an intense pulsed light emitter or a xenon lamp, the specific structure of which is well known to those skilled in the art, and will not be repeated here. Optionally, the beauty instrument 100 of the present application may be a hair removal instrument, or other instruments that need to dissipate heat during the beauty process, such as a skin rejuvenation instrument.

In some embodiments of the present application, as shown in FIG. 16 and FIG. 11 , the casing 1 includes a first end portion 0121 and a second end portion 0122 that are opposite and spaced apart, and connected between the first end portion 0121 and the second end portion 0121 . The two side wall surfaces 0112 are opposite and spaced between the ends 0122 .

Optionally, as shown in Figure 16, the first air inlet 1012 (see also Figure 12 for the specific structure of the first air inlet 1012) is formed on the first end 0121, and the first air outlet 1015 is formed on at least one side wall surface 0112 on. The airflow flows into the housing 1 through the first air inlet 1012 on the first end 0121 , flows in the direction of the first air outlet 1015 inside the housing 1 to dissipate heat, and then passes through the first air outlet 1015 on the side wall surface 0112 Flow out of the casing 1 to achieve the purpose of heat dissipation.

It should be noted that, by setting the first air inlet 1012 on the first end 0121 and the first air outlet 1015 on the side wall 0112 in this application, the distance between the first air inlet 1012 and the first air outlet 1015 can also be increased. The distance between them prolongs the residence time of the heat dissipation airflow in the casing 1, so that the heat dissipation airflow can fully exchange heat with the heat dissipation components and improve the heat dissipation efficiency.

Optionally, as shown in FIG. 16 and FIG. 15 , along the direction from the first end 0121 to the second end 0122 , the second heat dissipation element 122 , the heat dissipation cavity 023 , and the first heat dissipation element 121 are arranged in sequence. In order to rationally utilize the space between the first end 0121 and the second end 0122, on the one hand, it can simply and effectively ensure that the second heat sink 122 is located upstream of the heat dissipation cavity 023, and on the other hand, it can ensure that the beauty instrument after assembly The structure of 100 is more compact and small, which is easy to store and carry, and improves the user experience; on the other hand, the structure of the cooling part 02 is made more compact, the air duct is shorter, and the heat dissipation efficiency is improved.

Optionally, in the direction in which the first end 0121 is spaced apart from the second end 0122, the first air outlet 1015 is arranged closer to the first heat sink 121 relative to the second heat sink 122, so that the heat dissipation cavity can be ensured simply and effectively. 023 can also be located on the airflow path from the first air inlet 1012 to the first air outlet 1015, and be located downstream of the second heat sink 122 and upstream of the first air outlet 1015, so as to improve the reliability of air flow through the heat dissipation cavity 023 , improve the smoothness of air flow and the effectiveness of heat dissipation. In addition, because the first heat sink 121 mainly cooperates with the cooling element 5 to conduct heat, it can also be understood that, compared with the second heat sink 122, the temperature of the first heat sink 121 is higher, therefore, the first air outlet 1015 It is arranged close to the first heat sink 121, so that part of the heat on the first heat sink 121 can be directly exported from the first air outlet 1015, further improving heat dissipation efficiency, reducing the temperature inside the casing 1, and improving user experience.

Optionally, a first air outlet 1015 is formed on each side wall surface 0112 . Make the beauty instrument 100 of the present application have two first air outlets 1015, like this, the heat inside the beauty instrument 100 will be exported more quickly, improve the heat dissipation performance of the beauty instrument 100, make the durability of the beauty instrument 100 can be greater With the improvement of the heat dissipation performance of the beauty instrument 100, the operating temperature of the beauty instrument 100 is reduced, and the user experience will not be affected by the heat of the beauty instrument 100 when using the beauty instrument 100.

Optionally, as shown in FIG. 13 , the first heat sink 121 includes a first side surface 02111 disposed toward the side wall surface 0112, and each first side surface 02111 is spaced apart from the corresponding side wall surface 0112 to form a communication The heat dissipation cavity 023 and the air outlet cavity of the first air outlet 1015 . It can also be understood that, by setting the first heat sink 121 spaced apart from the side wall surface 0112, during the airflow process, on the one hand, the airflow will flow through the first side surface 02111 of the first heat sink 121 to take away the first The heat of the heat sink 121 improves the heat dissipation effect of the first heat sink 121; on the other hand, the first heat sink 121 will not hinder the circulation of the airflow, thereby ensuring that the airflow entering the casing 1 from the first air inlet 1012 can flow smoothly to the first air outlet 1015, and flow out through the first air outlet 1015, so as to ensure smooth flow of air flow and achieve the purpose of heat dissipation.

Optionally, as shown in FIG. 13 , in the spaced direction of the two side wall surfaces 0112 , the width of the second heat sink 122 is greater than the width of the first heat sink 121 , and the second heat sink 122 includes The second side surfaces 02120, each second side surface 02120 is bonded to the corresponding side wall surface 0112. Wherein, the bonding can be that the second side surface 02120 is in direct contact with the side wall surface 0112 , or it can be that the second side surface 02120 is in indirect contact with the side wall surface 0112 through an intermediate seal.

Thus, since the width of the second heat sink 122 is larger than the width of the first heat sink 121, the area of the second heat sink 122 can be increased, on the one hand, it is convenient to form the second side surface 02120 and the corresponding side wall surface 0112; On the other hand, the larger the width of the second heat sink 122 is, the larger the heat dissipation area is, which improves the heat dissipation effect.

Because the second heat sink 122 is arranged on the airflow path from the first air inlet 1012 to the first air outlet 1015, and compared with the first heat sink 121, the second heat sink 122 is arranged closer to the first air inlet 1012, By setting the second heat sink 122 attached to the side wall surface 0112, in the process of air flow, the second heat sink 122 can limit the flow direction of the air flow, on the one hand, avoid the air flow entering from the first air inlet 1012 directly from the first The side of the second heat sink 122 is bypassed, without heat exchange with the second heat sink 122, the heat exchange short circuit problem that directly flows out from the first air outlet 1015, on the other hand, avoids the air flow flowing to the downstream of the second heat sink 122 toward The direction of the first air inlet 1012 is reversed, so as to ensure that the airflow entering the casing 1 from the first air inlet 1012 can smoothly flow through the second heat sink 122, then flow to the first air outlet 1015, and pass through the first air outlet 1015 flow out to ensure smooth airflow and achieve the purpose of heat dissipation.

Optionally, along the direction from the first end portion 0121 to the second end portion 0122 , the heat dissipation component 02 , the cooling element 5 , and the lighting assembly 2 are arranged in sequence, and a light emitting area is formed on the second end portion 0122 . That is to say, the first air inlet 1012 is set on the first end 0121, the light output area is set on the second end 0122, and the first air inlet 1012 and the light output area are set opposite to each other. In this way, in the process of using the beauty instrument 100 It will not affect the heat dissipation, and will not affect the light emission of the beauty instrument 100 during the heat dissipation process, which ensures the independence of light emission and heat dissipation, realizes heat dissipation while emitting light, reduces the temperature of the beauty instrument 100 during use, and improves user experience. And the heat dissipation component 02, the cooling component 5, and the lighting assembly 2 are sequentially arranged between the first end portion 0121 and the second end portion 0122 to further rationalize the utilization of the space between the first end portion 0121 and the second end portion 0122. Space ensures that the assembled beauty instrument 100 has a simpler, more compact and compact structure, which is convenient for storage and portability. Of course, the present application is not limited thereto. In other embodiments, the light emitting area can also be set at other positions, for example, set on the wall connected between the two side walls 0112, and at the same time adjust the position of the lighting assembly 2 accordingly. Set the location, which will not be described here.

In some embodiments of the present application, at least part of the first heat sink 121 is also disposed on the airflow path from the first air inlet 1012 to the first air outlet 1015 . When the first cooling fan 11 speeds up the flow of air, it can take away the heat on the first heat sink 121 and export it to the outside of the housing 1 through the first air outlet 1015, reducing the heat inside the housing 1 to achieve The purpose of cooling the inside of the casing 1 .

Optionally, the first heat dissipation element 121 is located downstream of the heat dissipation cavity 023 . It can be seen that the airflow will flow through the second heat sink 122, the heat dissipation cavity 023 and the first heat sink 121 in sequence during the circulation process, prolonging the residence time of the airflow in the housing 1 and effectively improving the heat exchange efficiency of the heat dissipation airflow .

Optionally, at least part of the cooling element 5 is also arranged on the airflow path from the first air inlet 1012 to the first air outlet 1015 , and the cooling element 5 is located downstream of the first cooling element 121 . The airflow flowing through the first cooling element 121 will pass through the cooling element 5 and then be discharged from the first air outlet 1015, so as to quickly take away the heat on the cooling element 5 and achieve the purpose of cooling the cooling element 5, thereby improving cooling The cooling effect of the component 5, in this way, can improve the burning sensation that occurs when the user uses the beauty instrument 100, enhance the user experience, and thus improve the practicability of the beauty instrument 100.

In some embodiments of the present application, as shown in FIG. 16 and FIG. 17 , the two sides of the thickness of the cooling element 5 are the cold end surface 0321 and the hot end surface 0311 respectively. It can be understood here that the cooling element 5 includes a cold end surface 0321 and a hot end surface 0311, and the cold end surface 0321 and the hot end surface 0311 are arranged oppositely in the thickness direction of the cooling element 5, that is, in the thickness direction of the cooling element 5 direction, one side of the cooling element 5 has a cold end surface 0321 , and the other side of the cooling element 5 has a hot end surface 0311 .

The cooling element 5 can specifically be a semiconductor cooling chip, or a liquid cooling radiator, etc., and its specific structure is well known to those skilled in the art, and will not be repeated here.

It should be noted that, the thickness direction of the cooling element 5 mentioned above may be the up-down direction shown in FIG. 16 .

Optionally, the thickness side surface of the first heat sink 121 facing away from the heat dissipation cavity 023 is disposed toward the hot end surface 0311 and completely covers the hot end surface 0311 . Thus, setting the first heat sink 121 completely covering the hot end surface 0311 can increase the heat transfer area between the first heat sink 121 and the hot end surface 0311, so that the first heat sink 121 can absorb the hot end more quickly and comprehensively. Surface 0311 heat, improve heat dissipation efficiency.

Optionally, the first heat sink 121 is set to be attached to the hot end surface 0311, that is, directly or indirectly fit without gaps, for example, the first heat sink 121 is in direct contact with the hot end surface 0311, or the first heat sink 121 Indirect contact with the hot end surface 0311 through thermal conductive glue, etc., so that the heat on the hot end surface 0311 can be fully transferred to the first heat sink 121, and transferred to the second heat sink 122 through the first heat transfer connector 123, improving Heat transfer efficiency, thereby improving heat dissipation efficiency.

In some embodiments of the present application, as shown in FIG. 17 and FIG. 15 , the first heat dissipation fan 11 is disposed in the heat dissipation cavity 023 formed by the first heat dissipation element 121 and the second heat dissipation element 122 . Such setting ensures that the first heat dissipation fan 11 can effectively increase the air flow efficiency while the first heat dissipation fan 11 will not occupy the space other than the first heat dissipation device 12, further ensuring that the beauty instrument 100 after assembly is more compact and small in structure, It is easy to store and carry, improves user experience, and ensures the compact structure of the heat dissipation component 02 to improve heat dissipation efficiency.

In some embodiments of the present application, the first heat dissipation fan 11 is arranged closer to the second heat dissipation element 122 relative to the first heat dissipation element 121 . That is to say, the first heat dissipation fan 11 is set far away from the first heat dissipation element 121 relative to the second heat dissipation element 122. Since the first heat dissipation element 121 cooperates with the cooling element 5 to conduct heat, compared with the second heat dissipation element 122, the first heat dissipation element 122 The temperature of part 121 is relatively high, and the above-mentioned setting can avoid the heat transfer on the first heat dissipation part 121 to the first heat dissipation fan 11 to affect the first heat dissipation fan 11, prolong the service life of the first heat dissipation fan 11, and reduce the 100 usage cost.

In some embodiments of the present application, the first heat sink 121 and the second heat sink 122 are arranged in parallel. That is, the thickness direction of the first heat dissipation element 121 is the same as the thickness direction of the second heat dissipation element 122, both of which are the thickness direction of the heat dissipation component 02, so that in the thickness direction of the heat dissipation component 02, the distances in the heat dissipation cavity 023 are equal , so as to ensure that the available installation space of the first heat dissipation fan 11 is large, and the specification and ventilation capacity of the first heat dissipation fan 11 are improved, thereby improving the heat exchange efficiency of the heat dissipation airflow. Of course, the present application is not limited thereto. For example, in other embodiments, the thickness direction of the first heat sink 121 and the thickness direction of the second heat sink 122 may also have a certain angle, so that the first heat sink 121 and the second heat sink Members 122 are arranged non-parallel.

In some embodiments of the present application, as shown in FIG. 15 , the first cooling fan 11 may include a fan casing 111 and a fan, and the fan is arranged in the fan casing 111 . The fan is used to speed up the flow of the airflow during the working process, so as to guide the external normal temperature air into the casing 1 for heat exchange, so as to achieve the purpose of heat dissipation, and the fan casing 111 can play the role of forming an air duct and protecting the fan. Ensure the ventilation effect and prolong the service life of the fan.

Optionally, as shown in FIG. 18 and FIG. 15 , the side of the fan case 111 facing the second heat sink 122 has a fan inlet 0222 , and the side of the fan case 111 facing the first heat sink 121 has a fan outlet 0223 . Optionally, as shown in FIG. 18 and FIG. 15 , the fan casing 111 defines a guide air duct 11a extending from the fan inlet 0222 to the fan outlet 0223, and at least part of the airflow in the heat dissipation cavity 023 passes through the guide air duct 11a . The guide air duct 11a is used to define the flow path of the airflow, so as to guide the flow of the airflow, so as to ensure that the airflow entering the first cooling fan 11 from the fan inlet 0222 can flow out from the fan outlet 0223 smoothly.

It should be noted that the heat dissipation cavity 023 is defined by the side surface of the first heat dissipation element 121 facing the second heat dissipation element 122 and the side surface of the second heat dissipation element 122 facing the first heat dissipation element 121 . For example, as shown in FIG. 13, the upper surface of the first heat sink 121 and the lower surface of the second heat sink 122 are jointly defined, and the first heat dissipation fan 11 is arranged on the upper surface of the first heat sink 121 and the second heat sink. Inside the heat dissipation cavity 023 between the lower surfaces of the heat dissipation element 122 .

If the upper and lower ends of the fan case 111 abut against the first heat sink 121 and the second heat sink 122 respectively, the height of the guide air duct 11a in the up and down direction is equal to the height of the heat dissipation cavity 023 in the up and down direction, and the heat dissipation cavity Most of the airflow in 023 passes through the guide air duct 11a.

If the lower end of the fan case 111 does not contact the first heat sink 121, and/or the upper end of the fan case 111 does not contact the second heat sink 122, the height of the guide air duct 11a in the vertical direction is smaller than the heat dissipation cavity 023 At heights in the up and down direction, the air inlet and/or outlet air of the guiding air duct 11 a needs to pass through the heat dissipation cavity 023 .

Wherein, the first heat dissipation fan 11 is arranged between the first heat dissipation element 121 and the second heat dissipation element 122, and the fan inlet 0222 of the first heat dissipation fan 11 is arranged towards the second heat dissipation element 122 to ensure that the second heat dissipation element 122 side The negative pressure is reliably formed, thereby improving the reliability of the air flow passing through the second heat sink 122 and exchanging heat with the second heat sink 122 , which can effectively improve the heat dissipation efficiency of the second heat sink 122 . At the same time, the fan outlet 0223 of the first cooling fan 11 is arranged towards the first heat sink 121 to ensure that the airflow derived from the fan outlet 0223 can act on the first heat sink 121 to dissipate heat from the first heat sink 121, which can effectively The heat dissipation efficiency of the first heat dissipation element 121 is improved.

It should be noted that, since the guide air duct 11a is provided, and the fan inlet 0222 and the fan outlet 0223 are set to cooperate with each other, the airflow entering the first cooling fan 11 from the fan inlet 0222 will follow the guide air duct 11a The air flows in the extension direction of the airflow, and does not flow to other locations, which effectively improves the utilization rate of the airflow, thereby improving the heat dissipation efficiency.

Optionally, as shown in FIG. 18 , a drainage surface 02110 is formed on the first heat sink 121 , and the drainage surface 02110 extends smoothly along the direction from the fan inlet 0222 to the first air outlet 1015 . When the heat dissipation component 02 dissipates heat to the hot end surface 0311 of the cooling element 5, the airflow entering from the fan inlet 0222 can be quickly transferred to the first air outlet 1015 through the air guide surface 02110, and then exported to the casing through the first air outlet 1015 1, the drainage surface 02110 reduces the barrier to air flow, achieves the purpose of heat dissipation, and improves heat dissipation efficiency.

In some schemes, the light source of the lighting assembly 2 is located on the housing 1 or extends out of the housing 1. At this time, the chamber is outside the housing 1, and the chamber is the space through which the light is emitted. When the cooling component 5, the lighting component 2, and the heat dissipation component 02 are all arranged in the casing 1, on the one hand, the above components do not occupy the space outside the casing 1, ensuring that the beauty instrument 100 forms an integral structure, which is convenient for storage and carrying; On the one hand, the housing 1 can protect the above-mentioned components. During the use of the beauty instrument 100, external hard objects will not cause damage to the above-mentioned components, prolonging the service life of the above-mentioned components, thereby reducing the use cost of the beauty instrument 100. Improve user experience.

The cooling element 5 has a cold end and a hot end, and the cold end is in contact with the lighting assembly 2 . The refrigerating part 5 is a cooling part. During operation, the refrigerating part 5 transfers heat from the cold end to the hot end, so that the cold end can deliver cold to the outside, and the hot end can deliver heat to the outside. In some schemes, the cooling element 5 is a semiconductor cooling element. After the semiconductor cooling element is powered on, it absorbs heat from the cold end and releases heat from the hot end. For example, the semiconductor cooling element is a thermocouple structure composed of N-type semiconductor materials and P-type semiconductor materials. The principle of the semiconductor refrigeration unit is the prior art, and will not be repeated here. The shape of the cooling element 5 is not specifically limited here. In another solution, the cooling element is a liquid-cooled first heat sink, and the liquid transfers heat in circulation.

The heat dissipation component 02 includes a first heat dissipation device 12 and a first heat dissipation fan 11 . The first heat dissipation device 12 is on the side of the lighting assembly 2 away from the light emitting direction, that is, the first heat dissipation device 12 is on the opposite side of the rubber bristle assembly 5 to the light emitting direction. The first heat dissipation device 12 is a device that transfers the heat generated by the components during operation in time to avoid affecting the normal operation of the components. In the solution of this application, the first heat dissipation device 12 adopts an air-cooled first heat dissipation device. The first heat sink 12 absorbs heat by utilizing its high thermal conductivity, and dissipates heat into the air by utilizing its contact with the air.

The first heat sink 12 includes: a first heat sink 121, a second heat sink 122 and a first heat transfer connector 123, the first heat sink 121 and the second heat sink 122 are arranged along the first direction, the first heat sink 121 In contact with the hot end of the cooling element 5 , the first heat transfer connecting member 123 is used to connect the first heat sink 121 with the second heat sink 122 to form heat transfer.

In this way, the cooling element 5 releases cold energy to the lighting assembly 2 , transfers the heat to the first heat dissipation element 121 , and dissipates heat through the first heat dissipation element 121 . At the same time, the first heat sink 121 also transfers heat to the second heat sink 122 through the first heat transfer connection 123 , and the heat is dissipated by the second heat sink 122 and the first heat transfer connection 123 .

The first cooling fan 11 is used to drive the airflow, and the airflow driven by the first cooling fan 11 flows through at least one of the first cooling element 121 and the second cooling element 122 . Here, between the two cooling elements, the airflow driven by the first cooling fan 11 may only flow through the first cooling element 121, the airflow driven by the first cooling fan 11 may only flow through the second cooling element 122, and the first cooling fan 11 may only flow through the second cooling element 122. The airflow driven by 11 can flow through the first heat sink 121 and the second heat sink 122 . Regardless of whether it flows through the first heat sink 121 or the second heat sink 122 , the air can absorb heat from the first heat sink 12 to improve the heat dissipation efficiency of the first heat sink 12 . It should be noted that the airflow driven by the first heat dissipation fan 11 can communicate with the external airflow of the housing 1, or the airflow driven by the first heat dissipation fan 11 can also only flow in the housing 1, and slowly transfer heat outward in the internal circulation. Disperse.

The area of the projected overlapping area of the first heat sink 121 and the second heat sink 122 along the first direction is S1, the area of the largest side of the first heat sink 121 is S2, and the area of the largest side of the second heat sink 122 is S3, S1 accounts for more than half of at least one of S2 and S3. The projection along the first direction herein refers to the projection of the object on the vertical plane of the first direction. Taking the Cartesian coordinate system as an example here, assuming that the first direction is the X direction, the projection of the object along the first direction refers to the projection of the object on the YOZ plane. That is to say, the projected overlapping area of the first heat sink 121 and the second heat sink 122 on the YOZ plane is S1, and S1 may occupy more than half of S2, or S1 may occupy more than half of S3, or S1 is half of S2. The above is also more than half of the S3. As a result, at least one of the first heat sink 121 and the second heat sink 122 can have a larger area towards the lighting assembly 2 and the cooling element 5, and can absorb more heat no matter it is heat conduction or convection, so as to improve the performance of the lighting system. The heat dissipation effect of the optical component 2 and the cooling element 5 .

According to the beauty instrument 100 of the embodiment of the present application, the lighting component 2 will generate more heat during the working process. Through the setting of the cooling element 5 and the heat dissipation component 02, the cold end of the cooling component 5 transfers cold energy to the lighting component 2, so as to Reducing the temperature of the lighting assembly 2 during the working process prolongs the service life of the lighting assembly 2 on the one hand, and prevents the lighting assembly 2 from transferring heat to other components, causing the user to feel burning pain when using the beauty instrument 100 . By arranging the first heat sink 2 and the lighting assembly 1 along the first direction, the main functional components inside the beauty instrument 100 are arranged along the first direction, and the structure is compact, which is beneficial to reduce the overall volume.

Optionally, the beauty instrument 100 of the present application may be a hair removal instrument, or other instruments that use the lighting assembly 2 during the beauty process.

In some embodiments, as shown in FIG. 11 , the housing 1 includes a housing base 011 and a housing cover 012 , one side of the housing base 011 is open, and the housing cover 012 fits on the opening of the housing base 011 . The shell base 011 and the shell cover 012 are two independent parts. During the assembly process of the beauty instrument 100, components such as the cooling component 5, the lighting component 2, and the heat dissipation component 02 can be assembled in the shell base 011 first, and then the shell The cover 012 is connected to the shell base 011 to reduce the difficulty of assembling the beauty instrument 100 .

In some solutions, after the shell 1 is assembled, the shell base 011 and the shell cover 012 are fixed, and will not be opened during the service life, for example, they are fixed by welding or riveting. In some schemes, the shell cover 012 is detachably connected to the shell base 011, which is convenient for disassembly when the cooling element 5, the lighting assembly 2, the heat dissipation component 02, etc. in the shell 1 are damaged or need maintenance. The detachable connection mentioned here may adopt connection methods such as bolt connection or card connection.

In the solution of the present application, the shape of the shell 1 is not specifically limited, for example, it may be rectangular, cylindrical, etc., and for example, the shell 1 may include multiple segments, and different segments have different shapes or thicknesses.

In other embodiments, the casing 1 can also be spliced by two left and right half-shells, the two half-shells are open on the side facing each other, and the two half-shells are buckled into one casing 1 .

In some specific embodiments, as shown in FIG. 10 , the casing 1 includes a handpiece head 0171 and a gripping portion 1003 , and the gripping portion 1003 is connected to the handpiece head 0171 . The setting of the holding part 1003 is convenient for the user to hold and use force to align the handpiece head 0171 to the position requiring cosmetic treatment. The shape of the grip portion 1003 should be convenient to hold, and the specific shape is not limited.

For example, in FIG. 11 , the handpiece head 0171 is in the shape of an irregular cuboid, and the gripping portion 1003 is in the shape of a rod.

Specifically, the lighting component 2, the cooling element 5 and the heat dissipation component 02 are all arranged in the head part 0171, so that the functional components can be concentrated in the head part 0171, and the size of the grip part 1003 is not limited, which is beneficial to Under the premise of compact internal components, the overall size is reduced.

Specifically, as shown in FIG. 10 , the first heat transfer connector 123 has a bent section 02133 , and the bent section 02133 is disposed adjacent to the holding portion 1003 , or the bent section 02133 is at least partly located in the holding portion 1003 . The position of the bending section 02133 indicates that the first heat transfer connecting piece 123 is bent on the side where the holding portion 1003 is located, so that both ends of the first heat transferring connecting piece 123 can be connected to the first heat sink 121 and the second heat sink 122, and does not hinder the arrangement of the first heat sink 121 and the second heat sink 122 along the first direction. Moreover, the bent section 02133 utilizes the space of the grip portion 1003, or utilizes the space adjacent to the grip portion 1003, so that the internal structure of the handpiece 0171 is compact.

Optionally, a baffle 1017 for blocking air flow is provided between the grip portion 1003 and the head 0171, which can effectively prevent or reduce heat transfer to the grip portion 1003, and effectively slow down or prevent the grip portion 1003 from being hot. Condition.

In some solutions, the first heat transfer connector 123 does not have a bent section 02133, and the first heat transfer connector 123 can be straight rod or layered, for example, the first heat transfer connector 123 is a first heat sink 121, the thermal conduction layer between the second heat sink 122, and the like.

In some specific embodiments, the housing 1 is assembled from two parts, the housing base 011 and the housing cover 012 , one side of the housing base 011 is open and covered by the housing cover 012 . On the other side of the shell seat 011 , a section protrudes along the first direction, so that the protruding part forms a deep cavity inside, which is used for installing the cooling element 5 , the lighting assembly 2 , the heat dissipation component 02 and the like. The protruding part corresponds to the head part 0171 of the housing 1 , and the non-protruding part constitutes the handle section 172 of the housing 1 . A baffle 1017 is integrally formed in the shell seat 011 , and the baffle 1017 is located in the handle section 172 , so that the baffle 1017 can avoid the first heat transfer connecting piece 123 .

Specifically, the baffle 1017 is at least one layer, which plays a role of blocking air circulation.

In some embodiments, as shown in FIG. 11 , the casing 1 includes: a handpiece head 0171 and a gripping portion 1003 , and the lighting assembly 2 , cooling element 5 and heat dissipation component 02 are all arranged in the handpiece head 0171 . The light-emitting area of the casing 1 is set on the head 0171 . Wherein, the holding part 1003 is formed by extending a part of the handpiece head 0171 away from the light emitting area along a direction perpendicular to the first direction, so that the beauty instrument 100 is in the shape of a "7". Therefore, the heavy parts of the beauty instrument 100 are mainly concentrated in the head part 0171, and the grip part 1003 is relatively light and labor-saving, and the holding posture is more comfortable when performing beauty treatments on different parts of the body.

Moreover, the weight of the machine head 0171 is heavy. After the user holds the grip 1003 and brings the light-emitting area close to the skin or sticks it to the skin, the weight of the machine head 0171 can make it easier for the machine head 0171 to compress the skin. In this way, the possibility of damaging the surrounding skin by the light emitted by the lighting assembly 2 can be effectively reduced. When the beauty instrument 100 is in normal use, it is not easy to leak light, and it can also reduce the probability of light entering the eyes of the user or the surrounding people, so the safety is higher.

Specifically, the controller of the beauty instrument 100 can be disposed in the grip portion 1003 , or at least part of the circuits of the beauty apparatus 100 can be located in the grip portion 1003 . In this way, the inner space of the grip part 1003 can be fully utilized, and the weight of the grip part 1003 will not be increased too much. Placing the controller or the circuit on the holding part 1003 can allow the space of the machine head 0171 to help reduce the overall size of the machine head 0171 and make the machine head 0171 more compact.

Optionally, the controller can be a circuit board or an electric control box.

In some specific embodiments, the cross-sectional area of the handpiece head 0171 gradually decreases toward the light-emitting area, and the cross-sectional area refers to the area of the handpiece head 0171 on a plane perpendicular to the first direction. For example, the light emitting area is located at the lower end of the nosepiece 0171, and the cross-sectional area of the nosepiece 0171 decreases gradually in the downward direction. The upper end of the machine head 0171 is big like this, can provide enough accommodating space, and the lower end of the machine head 0171 is small, can reduce the contact area of the machine head 0171 and the skin, is conducive to increasing the pressure, and makes the machine head 0171 press more on the skin tight.

Also in some other specific embodiments, the width of the handpiece head 0171 gradually decreases in the direction toward the light-emitting area, and the width refers to the direction of the handpiece head 0171 perpendicular to the first direction and perpendicular to the grip portion 1003 size of. For example, the light emitting area is located at the lower end of the nosepiece 0171, and the nosepiece 0171 becomes narrower as it goes downward. This also allows the contact area between the nosepiece 0171 and the skin to be smaller, which is conducive to increasing the pressure, so that the nosepiece 0171 is pressed more tightly on the skin.

In some embodiments of the present application, as shown in FIG. 13 , there is a cooling air duct 102 inside the housing 1 , and the first cooling fan 11 makes the cooling air duct 102 circulate air. The heat dissipation air duct 102 can guide the incoming airflow, so that the airflow can flow according to the preset flow direction, and flow out of the beauty instrument 100, so as to improve the heat dissipation efficiency.

Specifically, a first air outlet 1015 and a first air inlet 1012 communicating with the cooling air passage 102 are formed on the casing 1 . During the working process of the first heat dissipation fan 11, the outside normal temperature air enters the heat dissipation air passage 102 in the casing 1 through the first air inlet 1012, and then flows along the extending direction of the heat dissipation air passage 102 to take away heat. It is discharged from the first air outlet 1015 to ensure smooth and stable discharge of heat and improve heat dissipation efficiency.

Optionally, as shown in FIG. 10 and FIG. 13 , the hot end surface 0311 of the cooling element 5 is set in the heat dissipation air duct 102 , and when the first heat dissipation fan 11 is working, the airflow entering through the first air inlet 1012 passes through the heat dissipation air. The channel 102 blows to the hot end surface 0311 of the refrigeration element 5, thereby taking away the heat from the hot end surface 0311, and then discharges the heat from the first air outlet 1015 to achieve the purpose of heat dissipation.

In some embodiments, the first heat dissipation fan 11 drives the air to be sucked in from the first air inlet 1012 , and then discharged from the first air outlet 1015 after passing through the first heat dissipation device 12 . The first cooling element 121 is located upstream or downstream of the second cooling element 122 in the flow direction of the airflow. That is to say, the airflow driven by the first cooling fan 11 may first flow through the first cooling element 121 and then flow through the second cooling element 122 , or may first flow through the second cooling element 122 and then flow through the first cooling element 121 . Although the heat dissipation sequence is different, the purpose of heat dissipation can be achieved.

Specifically, the first air inlet 1012 is located on a side of the second heat sink 122 away from the first heat sink 121 , so that the first air inlet 1012 blows air directly to the second heat sink 122 . It can be understood that the first air inlet 1012 has the greatest chance of contacting the outside air, and the distance to the outside is short. Therefore, such setting can make the air flow rate of the second heat sink 122 large.

Further, at least part of the first air outlet 1015 is located on a side of the first heat sink 121 away from the second heat sink 122 . In this way, the blowing path of the airflow in the casing 1 is far, and the heat absorption range of the airflow is larger.

In some specific embodiments, as shown in FIG. 10 and FIG. 11 , the first air inlet 1012 is arranged on the shell cover 012, and the first air inlet 1012 is arranged facing the heat dissipation component 02, so that the inlet air blows through the heat dissipation element when the temperature is the lowest. Component 02 has high heat exchange efficiency.

Specifically, the first air outlet 1015 is provided on the housing base 011 , so that the first air outlet 1015 is adjacent to components near the lighting assembly 2 .

Of course, the positions of the first air inlet 1012 and the first air outlet 1015 in the solution of this application can be adjusted according to needs, for example, the positions of the first air inlet 1012 and the first air outlet 1015 in Fig. It flows through the first heat sink 121 and finally flows through the second heat sink 122 to be discharged.

In some embodiments, the first heat sink 121 and the second heat sink 122 are arranged at intervals, and an intermediate cavity is formed between them, so that the two heat sinks can be spread out, so that heat can be diffused into a larger space.

In some embodiments, the first heat sink 121 and the second heat sink 122 are spaced apart in the first direction, and there is an intermediate cavity between them. Here, the projection overlapping area of the first heat sink 121 and the second heat sink 122 along the first direction is the same as the projection of the intermediate cavity along the first direction. That is to say, the space separated between the first heat sink 121 and the second heat sink 122 is an intermediate cavity, and the intermediate cavity can be left empty so that heat can be diffused into the intermediate cavity. This intermediate cavity can also accommodate components.

The reason why the middle cavity is formed here is that the first heat sink 121 and the second heat sink 122 are on both sides of the middle cavity, and enough heat can be absorbed in the middle cavity to cool down the first heat sink 121 and the second heat sink 122, so that the first heat sink 121 and the second heat sink 122 are cooled. The first heat sink 121 and the second heat sink 122 can absorb more heat from the lighting assembly 2 .

In this application, the first heat sink 121 and the second heat sink 122 are spaced apart in the first direction, and the first heat sink 121 and the second heat sink 122 are arranged face to face, so that the area of the intermediate cavity formed between them is Large, large heat holding capacity. In the solution of the present application, when the first cooling fan 11 is provided in the housing 1 , a cooling air duct 102 is formed in the housing 1 . The airflow driven by the first heat dissipation fan 11 flows along the heat dissipation air duct 102 , and the heat dissipation air duct 102 can guide the air flow so that the air flow follows a preset flow direction. In this way, the flow direction of the airflow is orderly, which can not only reduce the energy consumption due to wind resistance, but also allow the airflow to flow through the first cooling device 12, and even flow through the cooling element 5, so as to increase the heat exchange capacity between the above-mentioned elements and the air.

In some specific embodiments, the airflow driven by the first cooling fan 11 flows through the middle cavity, that is to say, the middle cavity is a middle ring of the cooling air channel 102 . Since both sides of the middle cavity are heated, the middle cavity becomes a heat accumulation area, so the airflow driven by the first heat dissipation fan 11 flows through the middle cavity, and the concentrated heat is blown away by the airflow, and the heat exchange efficiency is high.

As the temperature of the radiated heat sink drops, the heat concentrated in the middle cavity and the heat sink with a higher temperature can be quickly transferred to the heat sink with a lower temperature, thereby rapidly cooling down and increasing the cooling rate.

In some embodiments, the first heat dissipation fan 11 is an axial flow fan, and the rotating shaft of the first heat dissipation fan 11 is arranged along the first direction. The extension line of the rotating shaft of the first cooling fan 11 passes through the cooling element 5 and is arranged. In this way, the air flow through the first heat sink 121 and the second heat sink 122 can be larger, the air fluidity is the strongest, and the heat dissipation performance is higher.

In some specific embodiments, the first heat dissipation element 121 and the second heat dissipation element 122 are arranged at intervals, and the first heat dissipation fan 11 is arranged between the first heat dissipation element 121 and the second heat dissipation element 122. On the one hand, it is ensured that the first heat dissipation fan 11 does not It will occupy the space outside the first heat dissipation device 12, making the structure of the heat dissipation component 02 more compact, thereby ensuring that the overall volume of the beauty instrument 100 will be smaller, easy to use, store and carry, and improve user experience; on the other hand, the heat dissipation component 02 In 02, the relative position setting of the first heat sink 121, the second heat sink 122, and the first heat dissipation fan 11 and the mutual cooperation and heat dissipation relationship can improve the heat dissipation efficiency.

Of course, in some other examples, the first heat dissipation fan 11 is not limited to being arranged between the first heat dissipation element 121 and the second heat dissipation element 122, and the first heat dissipation fan 11 can also be arranged in other positions, for example: the first heat dissipation fan 11 The fan 11 is disposed on a side of the second heat sink 122 away from the first heat sink 121 , or the first heat dissipation fan 11 is disposed on a side of the second heat sink 122 , or the like. The specific setting position of the first heat dissipation fan 11 is not limited, as long as the first heat dissipation fan 11 can make the air flow in the heat dissipation air channel 102 flow during the working process.

Optionally, the first heat dissipation fan 11 is disposed between the first heat dissipation element 121 and the second heat dissipation element 122 and is disposed close to the second heat dissipation element 122 . That is to say, the first heat dissipation fan 11 is set far away from the first heat dissipation element 121 relative to the second heat dissipation element 122. Because the first heat dissipation element 121 is arranged close to the hot end surface 0311 of the cooling element 5, the temperature of the first heat dissipation element 121 itself is relatively high. High, setting the first heat dissipation fan 11 away from the first heat dissipation element 121 can prevent the heat of the first heat dissipation element 121 from being transferred to the first heat dissipation fan 11 , and prolong the service life of the first heat dissipation fan 11 .

In some specific embodiments, both ends of the first heat transfer connecting member 123 are respectively connected to the first heat sink 121 and the second heat sink 122 , and the first heat transfer connecting member 123 is disposed away from the middle cavity. Specifically, the part of the first heat transfer connecting member 123 between the first heat sink 121 and the second heat sink 122 is not in the middle cavity, and can be arranged from the side of the middle cavity. In this way, the first heat transfer connecting piece 123 can reduce the flow resistance to the airflow, and when the intermediate cavity is installed with components, the interference with the first heat transfer connecting piece 123 is also small.

In some embodiments, the first heat transfer connection part 123 is in contact with the hot end of the cooling element 5 . It can be understood that the thermal conductivity of the first heat transfer connecting part 123 is relatively high. When it is in contact with the hot end of the cooling element 5, the heat of the heating element 3 can be quickly transferred, and then the heat can be quickly transferred to the first heat sink 121. , The second heat sink 122 spreads out.

In some embodiments, the first heat transfer connector 123 is an elbow, so that when connecting the first heat sink 121 and the second heat sink 122 , the position of the first heat transfer connector 123 can be flexibly arranged.

The first heat transfer connecting member 123 is provided with a heat conduction medium, the heat conduction medium is a fluid, and the conductivity of the heat conduction medium is greater than that of air. Optionally, the first heat transfer connector 123 forms a hollow structure inside, for example, the first heat transfer connector 123 is formed as a heat transfer tube, and a cooling medium is provided inside the heat transfer tube, and the cooling medium is used to turn the first heat sink The heat in 121 is transferred to the second heat sink 122 to achieve the purpose of dissipating heat from the surface 0311 of the hot end. The cooling medium mentioned here may be one of cooling water, cooling liquid or cooling gas.

Specifically, as shown in FIG. 18 and FIG. 16 , both ends of the first heat transfer connector 123 are respectively inserted into the first heat sink 121 and the second heat sink 122 . In this way, on the one hand, plug-in fit can be used, and the installation and fixing of the first heat transfer connector 123 can save the steps of screwing and welding; The contact area of the two heat sinks 122 improves the heat transfer capability of the joint.

In some specific embodiments, the first heat transfer connector 123 includes: a first heat transfer end 02131, a second heat transfer end 02132 and a bent section 02133, the first heat transfer end 02131 is a first straight pipe section, and the second heat transfer end The hot end 02132 is the second straight pipe section, the first heat transfer end 02131 is inserted into the first heat sink 121, the second heat transfer end 02132 is inserted into the second heat sink 122, and the bent section 02133 is connected to the first heat transfer end 02131 and the second heat transfer end 02131. Two heat transfer ends 02132. The design of the straight pipe section makes the insertion labor-saving and fast.

Specifically, the bent section 02133 is connected to the same end of the first heat transfer end 02131 and the second heat transfer end 02132, and the first heat transfer connecting piece 123 is U-shaped. The processing equipment for U-shaped pipes is not only mature, but also has a high pass rate. Optionally, the end of the second heat transfer end 02132 away from the bent section 02133 is a pointed end, so that the second heat transfer end 02132 can be inserted into the second heat sink 122 with a pointed end, and the insertion resistance is reduced.

Further, there are two first heat transfer connectors 123, the first heat transfer ends 02131 of the two first heat transfer connectors 123 are parallel, and the second heat transfer ends 02132 of the two first heat transfer connectors 123 In parallel, there is an included angle between the bent sections 02133 of the two first heat transfer connectors 123 . The setting of the included angle stabilizes the relative angle and distance between the first heat dissipation element 121 and the second heat dissipation element 122 connected to the first heat transfer connection element 123 .

In some embodiments, the second heat sink 122 includes a plurality of fins 02126 arranged at intervals, and the fins 02126 extend along the first direction. The design of the fins 02126 can not only reduce the wind resistance of the airflow, but also increase the air flow, and the air duct formed between the two fins 02126 can guide the airflow to flow along the first direction. The direction of air flow is opposite to the direction of heat transfer, and convection can further improve heat transfer efficiency.

Specifically, the dimensions of the first heat sink 121 and the second heat sink 122 along the first direction are thickness, and the thickness of the first heat sink 121 is smaller than the thickness of the second heat sink 122 . That is to say, the first heat sink 121 is relatively thinner. Since the first heat sink 121 is in contact with the hot end of the refrigeration element 5, the temperature of the first heat sink 121 is relatively higher, and the first heat sink 121 is set to be thinner so that the heat absorbed by the first heat sink 121 from the hot end The transmission path along the first direction is shorter, and when air blows from the side of the first heat sink 121 adjacent to the second heat sink 122 , the heat can be taken away by the air as early as possible. If the first heat sink 121 dissipates heat through the second heat sink 122 , the heat of the first heat sink 121 can be transferred to the second heat sink 122 as soon as possible. Because the second heat sink 122 includes fins 02126 , the air flow is large, so the second heat sink 122 can dissipate heat as quickly as possible.

Further, the projected area of the first heat sink 121 along the first direction is smaller than the projected area of the second heat sink 122, that is, the projected area of the first heat sink 121 is relatively small, and the projected area of the second heat sink 122 is relatively small. larger. Such setting can match the heat dissipation methods of the first heat sink 121 and the second heat sink 122, and at the same time make the area of the first heat sink 121 relatively small, so that more air can circulate around the first heat sink 121 in the housing 1 , even the housing 1 is reduced in size at the first heat sink 121 .

Therefore, even though the projected area of the first heat sink 121 along the first direction is relatively small, the energy conduction capability of the first heat sink 121 is still strong, and heat can be quickly directed to the second heat sink 122 . The second heat sink 122 includes a plurality of fins 02126 , and its heat dissipation method is to use the contact area between the fins 02126 and the air to allow the flowing air to take away heat.

Moreover, there is no wind blowing to the lighting assembly 2, and the moisture in the air will not flow into the cooling space 016 to affect the circuits and devices, thereby improving the safety of electricity use. The probability of forming water and fog in the lighting assembly 2 can be reduced, and the service life of the lighting assembly 2 can be extended.

It should be noted that, since there are two independent spaces (radiation space 015 and cooling space 016 ) in the casing 1 of the present application, the cooling element 5 can be installed in the cooling space 015 or in the cooling space 016 . For example, in the example shown in FIG. 13, the hot end surface 0311 of the cooling element 5 is arranged in the heat dissipation space 015, and the cold end surface 0321 of the cooling element 5 is arranged in the cooling space 016, so as to ensure that the hot end surface 0311 can Set towards the heat dissipation component 02 to improve heat dissipation efficiency.

That is to say, the light-emitting element 22 is arranged in the installation cavity 2111, and the heat insulation cavity 2112 is arranged between the installation cavity 2111 and the light-transmitting cold compress 3, and the light-emitting element 22 is limited in the installation cavity 2111.

In this way, the cold energy transferred to the first cold-conducting part 0523 can be transferred to the light-transmitting cold compress 3 through the two heat-conducting parts 2101, so as to cool down the light-transmitting cold compress 3 and match the heat transfer of the light-transmitting cold compress 3 There can be an ice compress effect on the user's skin, thereby reducing the tingling sensation of the user during beauty treatment, and making the cold energy transmitted to the light-transmitting cold compress 3 more uniform, thereby improving user experience.

In addition, since the first cold conduction part 0523 cooperates with the cooling element 5 for heat transfer, and the heat conduction part 2101 cooperates with the light-transmitting cold compress 3 for heat transfer, the overall structure can be simplified, heat transfer efficiency can be improved, and heat loss can be reduced.
