DETAILED DESCRIPTION

It should be noted that, in the absence of conflict, the embodiments and technical features in the embodiments of the present application can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of the present application and should not be regarded as an improper limitation on the present application.

Please refer to FIG. 1 to FIG. 4 . In one aspect, an embodiment of the present application provides a heating component 1 . The heating component 1 includes a bracket 11 , a receiving tube 12 , and a first sealing member 13 .

Please refer to FIG. 3 to FIG. 5 . The support 11 is formed with a receiving cavity 11 a . The receiving tube 12 is received in the receiving cavity 11 a . A stopper 121 is formed at the bottom end of the receiving tube 12 . The receiving tube 12 is used to receive the aerosol generating substrate. At least part of the first sealing member 13 is sealed between the stopper 121 and the bottom surface of the receiving cavity 11a. That is, the first sealing member 13 can seal the gap between the stopper 121 and the bottom surface of the receiving cavity 11a.

Exemplarily, the heating component 1 can heat the aerosol generating substrate to below the ignition point to generate aerosol by atomization. In other words, the aerosol generating substrate is heated without burning. During the aerosol generating process, the temperature of the aerosol generating substrate is high, and the temperature of the receiving tube 12 is also high.

In the heating component 1 provided in the embodiment of the present application, on the one hand, the first sealing member 13 can isolate the stopper 121 and at least part of the bottom surface of the receiving chamber 11a, reduce the contact area between the receiving tube 12 and the bracket 11, thereby reducing the heat conduction between the receiving tube 12 and the bracket 11 and enhancing the heat insulation performance. On the other hand, during the process of assembling the aerosol generating matrix to the receiving tube 12, the stopper 121 provides a limiting function for the aerosol generating matrix, preventing the aerosol generating matrix from excessively moving toward the bottom side, and limiting the aerosol generating matrix from escaping from the receiving tube 12.

It should be noted that, in the present application, the top may be the direction in which the heating component 1 is close to the user during actual use, and the bottom is the direction opposite to the top.

Please refer to Figures 1 to 4. On the other hand, an embodiment of the present application provides an aerosol generating device, which includes a housing 2 and a heating component 1 in any embodiment of the present application. The housing 2 is formed with a placement cavity 2a, and the bracket 11 is accommodated in the placement cavity 2a.

The aerosol generating device provided in the embodiment of the present application uses a heating component 1 to atomize an aerosol generating matrix to form an aerosol in a heating-not-burning manner for the user to inhale. The bracket 11 provides support for the receiving tube 12, and the first sealing member 13 can reduce the area of direct contact between the receiving tube 12 and the bracket 11, thereby reducing the heat transferred to the housing 2, solving the problem of the housing 2 being hot to the touch.

The materials of the aerosol-generating substrate include, but are not limited to, medicines, nicotine-containing materials or nicotine-free materials, etc.

The aerosol generating substrate can be used as a disposable product. That is, the aerosol generating substrate is replaceable, and a new aerosol generating substrate is placed in the receiving tube 12 after the old aerosol generating substrate is used up.

The form of the aerosol-generating substrate is not limited. For example, the aerosol-generating substrate is solid. The generating substrate can be in the form of particles, filaments or aggregated into blocks. For example, the aerosol generating substrate is in the form of an elongated strip, such as a cylinder, an elliptical cylinder or a prism.

In one embodiment, referring to FIG. 3 and FIG. 4 , the top end of the bracket 11 is formed with an installation opening 11d communicating with the receiving cavity 11a, the receiving tube 12 and the first sealing member 13 are both assembled into the receiving cavity 11a through the installation opening 11d, and the heating component 1 includes a second sealing member 14, and at least part of the second sealing member 14 is sealed between the top end of the receiving tube 12 and the cavity surface of the receiving cavity 11a. In other words, the second sealing member 14 can seal the gap between the top end of the receiving tube 12 and the cavity surface of the receiving cavity 11a.

In this embodiment, the receiving tube 12 and the first sealing member 13 are assembled into the receiving cavity 11a through the installation opening 11d, which is simple to install and easy to operate. The top end of the receiving tube 12 is fixed by the second sealing member 14, and the bottom end of the receiving tube 12 is fixed by the first sealing member 13, which not only enables the receiving tube 12 to be stably fixed to the bracket 11, but also forms a spacing space between the outer peripheral surface of the receiving tube 12 and the circumferential surface of the receiving cavity 11a, so that the outer peripheral surface of the receiving tube 12 and the circumferential surface of the receiving cavity 11a are as far as possible from contact, thereby reducing the heat conduction between the receiving tube 12 and the bracket 11, and the spacing space can be filled with air, which is a poor conductor of heat, thereby enhancing the thermal insulation performance.

In one embodiment, referring to FIGS. 3 to 6 , the heating component 1 includes a frame 15, the frame 15 is formed with a second air passage 15a penetrating the bottom end thereof, a heating chamber 12a for placing an aerosol generating matrix is formed inside the receiving tube 12, a second air port 12b is formed at the top end of the receiving tube 12, the bottom end of the frame 15 is located at the mounting port 11d, the second air port 12b communicates with the second air passage 15a and the heating chamber 12a, and a portion of the second sealing member 14 is sealingly disposed between the top end of the receiving tube 12 and the circumferential surface of the second air passage 15a. That is, the second air passage 15a penetrates the bottom end of the frame 15. A portion of the second sealing member 14 is sealingly disposed between the top end of the receiving tube 12 and the cavity surface of the receiving chamber 11a, and another portion of the second sealing member 14 is sealingly disposed between the top end of the receiving tube 12 and the circumferential surface of the second air passage 15a.

In this embodiment, on the one hand, the first seal 13 and the second seal 14 can prevent the aerosol in the heating chamber 12a from entering the receiving chamber 11a, so that the aerosol in the heating chamber 12a enters the second air passage 15a as much as possible. On the other hand, the second seal 14 can not only seal the gap between the front end of the receiving tube 12 and the receiving chamber 11a, but also seal the gap between the front end of the receiving tube 12 and the rear end of the frame 15, so as to achieve the purpose of one object for multiple uses and save parts.

The frame 15 is fixed to the bracket 11. In some embodiments, the frame 15 can be detachably connected to the bracket 11. The detachable connection includes but is not limited to snap connection, screw connection or bolt connection, etc. In other embodiments, the frame 15 can be non-detachably connected to the bracket 11. The non-detachable connection includes but is not limited to gluing or welding, etc.

In one embodiment, please refer to Figures 3 to 6. A heating chamber 12a for placing an aerosol generating substrate is formed inside the receiving tube 12, a first air port 121a is formed on the stopper 121, and the cross-sectional area of the first air port 121a is smaller than the cross-sectional area of the heating chamber 12a. The bracket 11 is formed with a first air channel 11b, and the first air channel 121a communicates the first air channel 11b and the heating chamber 12a. Specifically, the first air channel 11b is located at the bottom side of the heating chamber 12a, and the first air channel 11b can transport air into the heating chamber 12a. The receiving tube 12 can generate heat to heat the aerosol generating substrate. The first air port 121a is used to supply air and aerosol to flow between the heating chamber 12a and the first air channel 11b. The cross-sectional area of the first air port 121a is smaller than the cross-sectional area of the heating chamber 12a, which can prevent the aerosol generating substrate from escaping from the heating chamber 12a through the first air port 121a.

In one embodiment, please refer to FIG. 4 and FIG. 5 , the receiving tube 12 includes a tube portion 122 and a plate portion 123. At least one end of the tube portion 122 in the length direction has an opening, and the internal space of the tube portion 122 is a heating chamber 12a. The plate portion 123 is located at one end of the tube portion 122 in the length direction. The plate portion 123 is a stopper 121 and forms a first air port 121a. In other words, the tube portion 122 is columnar, and the length of the tube portion 122 extends in the top-bottom direction. The receiving tube 12 has a simple structure, and the aerosol generating substrate can be assembled into the heating chamber 12a through the tube portion 122 away from the opening of the plate portion 123.

In some embodiments, taking a plane perpendicular to the top and bottom directions as a cross section, the cross-sectional shape of the tube portion 122 includes but is not limited to a circle, an ellipse, a polygon, or the like.

The shape of the frame 15 and the shape of the bracket 11 are not limited. For example, the tube 122 is in a columnar shape, as shown in Figures 3 to 6, the frame 15 and the bracket 11 can both be roughly in a hollow tube shape. In this way, the shapes of the receiving tube 12, the frame 15 and the bracket 11 are compatible, which not only facilitates the insertion of the receiving tube 12 into the bracket 11, but also facilitates the insertion of the rear end of the frame 15 into the receiving cavity 11a through the installation opening 11d.

In one embodiment, referring to FIGS. 3 to 6 , the first sealing member 13 includes a bottom plate 131 having a communication port 131a formed thereon, and the bottom plate 131 is sandwiched between the stopper 121 and the bottom surface of the receiving chamber 11a. Specifically, the communication port 131a communicates with the first air port 121a and the first air passage 11b. On the one hand, the bottom plate 131 can prevent The receiving tube 12 directly contacts the bracket 11 to reduce heat conduction. On the other hand, the bottom plate 131 is pressed tightly by the pressing force between the stopper 121 and the bracket 11 in the top-bottom direction, and the gap between the stopper 121 and the bottom surface of the receiving chamber 11a is sealed by the elastic deformation of the bottom plate 131, so as to achieve a sealing effect, so that the gas flows between the first gas port 121a and the first gas channel 11b through the connecting port 131a, and does not enter the receiving chamber 11a.

In one embodiment, please refer to Figures 3 to 5. The first sealing member 13 includes a circumferential plate 132 connected to the top surface of the bottom plate 131. The circumferential plate 132 surrounds the bottom plate 131 to jointly define a receiving groove 13a. The bottom end of the receiving tube 12 is placed in the receiving groove 13a. On the one hand, even if there are dimensional tolerances due to manufacturing reasons of the components, the bottom end of the receiving tube 12 can be assembled into the receiving groove 13a through the elastic deformation of the first sealing member 13, so as to be assembled into the receiving cavity 11a together. The receiving tube 12 is easy to assemble and the assembly defect rate is reduced. On the other hand, the circumferential plate 132 can isolate the circumferential surface of the receiving tube 12 from the circumferential surface of the receiving cavity 11a, further reducing the contact area between the receiving tube 12 and the bracket 11. On the other hand, the receiving groove 13a can limit the movement of the bottom end of the receiving tube 12, thereby preventing the movement of the receiving tube 12 from contacting the circumferential surface of the receiving cavity 11a.

Exemplarily, the stopper 121 can be inserted into the receiving groove 13a so that the receiving tube 12 and the first sealing member 13 form a whole, and then the whole formed by the receiving tube 12 and the first sealing member 13 is inserted into the receiving cavity 11a through the installation opening 11d. It is understandable that the stopper 121 and the receiving groove 13a can be assembled by a tight fit or an interference fit. In this way, the first sealing member 13 can tightly wrap the stopper 121, and the degree of freedom of the first sealing member 13 along the top and bottom directions is limited, which can prevent the first sealing member 13 from falling off from the receiving tube 12 during the assembly process.

In some embodiments, the first seal 13 is placed into the receiving cavity 11a along the top-bottom direction through the installation port 11d, which is simple to assemble and the size of the enclosure 132 along the top-bottom direction can be smaller. In this way, the contact area between the enclosure 132 and the receiving tube 12 can be reduced, thereby reducing heat transfer.

In some embodiments, referring to FIG. 6 and FIG. 8 , the first sealing member 13 may include only a bottom plate 131 without a surrounding plate 132 .

The material of the first sealing member 13 and the material of the second sealing member 14 are not limited. For example, the material of the first sealing member 13 and the material of the second sealing member 14 are both silicone.

In one embodiment, referring to FIG. 3 and FIG. 4 , the bottom end of the receiving cavity 11 a contracts inwardly to form a contraction Region 11c, the first seal 13 is located in the contraction region 11c. Taking the plane perpendicular to the top and bottom directions as the cross section, the cross-sectional area of the contraction region 11c is smaller than the cross-sectional area of other parts of the receiving chamber 11a. The cross-sectional area of other parts of the receiving chamber 11a is larger so that the spacing between the receiving tube 12 and the circumferential surface of the receiving chamber 11a is larger, and the distance between the circumferential surface of the contraction region 11c and the outer circumferential surface of the receiving tube 12 is smaller, which can not only limit the movement of the rear end of the receiving tube 12, but also facilitate the assembly of the first seal 13.

In one embodiment, please refer to Figures 6 to 8, the circumferential surface of the receiving cavity 11a is formed with guide ribs 111 extending in the top-bottom direction, and the guide ribs 111 abut against the circumferential surface of the receiving tube 12. The guide ribs 111 can not only be used for circumferential positioning of the receiving tube 12 to limit the movement of the receiving tube 12, but also the contact area between the guide ribs 111 and the receiving tube 12 is small, which can reduce the heat conduction of the receiving tube 12 to the bracket 11. The guide ribs 111 can also be used for guiding the receiving tube 12 during assembly. For example, when the receiving tube 12 is inserted into the receiving cavity 11a through the installation opening 11d along the top-bottom direction, the circumferential surface of the receiving tube 12 abuts against the guide ribs 111 to enter the receiving cavity 11a, so that the assembly of the receiving tube 12 is smoother and the assembly defect rate is reduced.

In one embodiment, please refer to Figures 6 to 8, the guide rib 111 is located at the bottom end of the receiving cavity 11a, and the first sealing member 13 is formed with a guide groove 13b, and part of the guide rib 111 is located in the guide groove 13b. In this way, on the one hand, the length of the guide rib 111 along the top and bottom directions is relatively short, so as to further reduce the contact area between the guide rib 111 and the receiving tube 12. On the other hand, it is beneficial for the first sealing member 13 to not be loosened after being assembled into the receiving cavity 11a.

In some embodiments, referring to Figures 6 to 8, there are multiple guide ribs 111, and the multiple guide ribs 111 are distributed at intervals along the circumference of the receiving cavity 11a. Preferably, the multiple guide ribs 111 are evenly distributed at intervals along the circumference of the receiving cavity 11a.

In some embodiments, referring to FIG. 6 to FIG. 8 , the number of the guide ribs 111 and the number of the guide grooves 13 b are both plural, and the guide grooves 13 b and the guide ribs 111 correspond one to one.

It should be noted that, in the present application, a plurality refers to a number including two and more than two.

In some embodiments, referring to FIGS. 3 to 6 , a portion of the bottom surface of the receiving cavity 11a is protruded to form a protrusion 112, the protrusion 112 abuts against the stopper 121, and the first sealing member 13 is located between the protrusion 112 and the circumferential surface of the receiving cavity 11a. In other words, the protrusion 112 and the circumferential surface of the receiving cavity 11a together form a clamping space, and the first sealing member 13 is located in the clamping space. For example, the protrusion 112 extends into the communication port 131a. On the one hand, the clamping space facilitates the positioning and assembly of the first sealing member 13 , and on the other hand, the protrusion 112 and the circumferential surface of the receiving cavity 11 a jointly restrict the movement of the first sealing member 13 in a direction perpendicular to the top and bottom directions, that is, restricts the radial movement of the first sealing member 13 along the receiving tube 12 .

In one embodiment, please refer to FIG. 3 and FIG. 4 , the second sealing member 14 includes an annular portion 141, the second air passage 15a passes through the rear end of the frame 15, the rear end of the frame 15 extends into the front end of the receiving tube 12 through the mounting port 11d, and the annular portion 141 is sealingly clamped between the outer peripheral surface of the receiving tube 12 and the circumferential surface of the second air passage 15a. It can be understood that the annular portion 141 is sleeved on the outer peripheral surface of the receiving tube 12. The gap between the front end of the receiving tube 12 and the frame 15 is sealed by the annular portion 141. Exemplarily, the outer peripheral surface of the annular portion 141 abuts against the circumferential surface of the second air passage 15a, so that the second sealing member 14 can be assembled at the rear end of the frame 15 to form a whole, and then the whole formed by the second sealing member 14 and the frame 15 is assembled to the front end of the receiving tube 12. In this way, on the one hand, even if there are dimensional tolerances of parts due to manufacturing reasons, the frame 15 and the receiving tube 12 can be assembled through the elastic deformation of the annular portion 141, which makes it easy to assemble the receiving tube 12 and reduces the assembly defect rate; on the other hand, since the frame 15 can provide support for the second sealing member 14 and avoid assembly deformation of the second sealing member 14 during the assembly process that affects the sealing effect, the size of the annular portion 141 along the top and bottom directions can be smaller to reduce the contact area between the annular portion 141 and the receiving tube 12, thereby further reducing heat conduction.

In one embodiment, please refer to FIG. 3 and FIG. 6 , the circumferential surface of the second air passage 15a is formed with a step surface 15a', and the front surface of the annular portion 141 and the front surface of the receiving tube 12 are both in contact with the step surface 15a'. With such a design, on the one hand, during the process of installing the second seal 14 to the frame 15, the second seal 14 can be positioned by the step surface 15a', which facilitates the installation of the second seal 14. On the other hand, during the process of installing the whole formed by the second seal 14 and the frame 15 to the receiving tube 12, the receiving tube 12 is positioned by the step surface 15a', so that the frame 15 can be quickly assembled to the set position.

In one embodiment, please refer to Figures 3, 4 and 6, the second sealing member 14 includes an annular flange 142 surrounding the outer periphery of the annular portion 141, and the annular flange 142 abuts against the circumferential surface of the receiving chamber 11a. Exemplarily, the frame 15 is located in front of the annular flange 142. This prevents the frame 15 from interfering with the elastic deformation of the annular flange 142. The annular flange 142 is used to seal the gap between the front end of the receiving tube 12 and the cavity surface of the receiving chamber 11a. Since the frame 15 can provide support for the second sealing member 14, the thickness of the annular flange 142 can be thinner, that is, the dimension of the annular flange 142 along the front-to-back direction is smaller, which can reduce the annular flange 142. The contact area with the bracket 11 further reduces heat conduction.

In one embodiment, referring to Fig. 1, Fig. 3 and Fig. 6, the heat generating assembly 1 includes a heat insulating member 16, and the heat insulating member 16 is sleeved on the outer periphery of the bracket 11. Exemplarily, the heat insulating member 16 is located in the placement cavity 2a. The heat insulating member 16 is used to isolate the bracket 11 and the housing 22 to further reduce heat transfer.

The heat insulating member 16 may be a solid poor conductor of heat. The heat insulating member 16 includes but is not limited to aerogel. Aerogel has good heat insulating properties and can effectively prevent heat transfer between the bracket 11 and the housing 22.

In one embodiment, referring to FIG. 3 and FIG. 6 , the heating component 1 includes a coil 17, and the coil 17 is wound around the outer periphery of the bracket 11. The coil 17 and the receiving tube 12 can be electromagnetic heating elements. In other words, the coil 17 can be an electromagnetic coil 17, and the receiving tube 12 generates eddy current self-heating in the magnetic field of the coil 17. Exemplarily, the heat insulation 16 surrounds the outside of the coil 17.

In some embodiments, the receiving tube 12 is a resistive heating element. In this case, the heating component 1 may not have the coil 17. In other embodiments, the receiving tube 12 may also be a microwave heating element or an infrared heating element.

In one embodiment, the aerosol generating device includes a battery, and the housing 22 is formed with a battery compartment for placing the battery. The battery is used to power the electronic components in the aerosol generating device. For example, the receiving tube 12 can be electrically connected to the battery. The receiving tube 12 converts the electrical energy of the battery into heat energy.
