Description

Aerosol generating device and atomization component thereof Technical field

The present invention relates to the field of atomization, and more specifically, to an aerosol generating device and an atomization assembly thereof.

Background technique

The heating-non-combustion atomization device is an aerosol-generating device that heats the atomization material in a low-temperature heating-non-combustion method to form an inhalable aerosol. Currently, the heating elements of heat-not-burn atomization devices on the market generally use ceramic heating elements or electric heating wires, and their heat transfer forms usually include direct heating and indirect heating.

A common form of direct heating is that the ceramic heating element directly contacts the atomizing material; another form of direct heating is to wrap an FPC electric heating film on the outer surface of the metal pot, and the inner surface directly contacts the atomizing material. These two forms directly transfer heat to the atomization material through thermal conduction, and have the characteristics of fast smoke production. However, if the ceramic heating element is used to directly contact the atomized material, the heating element is easily corroded by the extracts from the atomized material, and has a short service life. The ceramic heating element heats up slowly, the heat field distribution is difficult to adjust and is uneven, and the suction taste is poor. FPC electric heating films are generally made of polyimide as the base material. The long-term working temperature is generally less than about 170°C. The high temperature resistance is poor, the smoke rate and temperature control range are limited, and the taste adjustment is also limited.

Indirect heating often uses electric heating wires to directly heat the air. During suction, the hot air extracts the active ingredients of the atomized material. This method can heat the atomization material comprehensively and evenly, and has a good taste, but it consumes a lot of power, so it requires a large-capacity battery, making the atomization device bulky. In addition, the atomization speed is slow, especially the first puff of smoke. .

It can include a housing 40 and an atomization component 10 received in the housing 40. , power supply 20, motherboard 30. The power supply 20 is electrically connected to the atomization component 10 and the main board 30 respectively, and is used to provide electric energy to the atomization component 10 and the main board 30 . The atomization component 10 is used to receive the atomization matrix and heat the atomization matrix to generate aerosol after being powered on. The atomization matrix may include solid atomization materials in the form of plant grass leaves, pastes, etc.

As shown in FIGS. 3-7 , the atomization assembly 10 may include a storage assembly 14 , a heating pot 11 accommodated in the accommodation assembly 14 , and a heating element 12 provided in the heating pot 11 . The heating pot 11 is in the shape of a pot with an open top. An atomization chamber 110 for accommodating the atomization substrate 50 is formed in the heating pot 11 . An open port 112 connected to the atomization chamber 110 is formed on the top of the heating pot 11 . The receiving component 14 is used to receive and fix the heating pot 11. A receiving cavity 140 for receiving the heating pot 11 is formed in the receiving component 14. An opening 151 connected to the opening 112 is formed on the top of the receiving component 14 corresponding to the opening 112. The atomization matrix 50 can be loaded into the atomization chamber 110 through the opening 151 and the opening 112 in sequence, and atomization is generated in the atomization chamber 110 . The bottom of the receiving assembly 14 has a support arm 161 to support the heating pot 11 . The heating element 12 is electrically connected to the power supply 20 and is used to generate heat after being powered on to heat the atomization matrix 50 .

Specifically, the heating pot 11 includes a pot body 111, and the inner surface of the pot body 111 defines an atomization chamber 110. In some embodiments, the wall surface of the atomization chamber 110 can be a smooth curved surface, for example, an arc surface, which can make the wall surface of the atomization chamber 110 fully contact with the atomization substrate 50 and avoid the traditional rectangular heating pot. The disadvantage of uneven heating at right angles to the bottom of the pot. Specifically, in this embodiment, the pot body 111 is roughly in the shape of a hemispherical pot with an open top, that is, the inner surface and the outer surface of the pot body 111 are both hemispherical, so that the wall surface of the atomization chamber 110 is Hemispherical shape.

Furthermore, the heating pot 11 may also include a boss 113 provided at the bottom of the pot body 111 , and the heating pot 11 may be supported on the support arm 161 via the boss 113 .

The top surface of the support arm 161 can also be recessed downward to form a groove 1610 corresponding to the boss 113. The boss 113 is received in the groove 1610. The outer peripheral surface and the bottom surface of the boss 113 are respectively in contact with the inner peripheral surface and bottom surface of the groove 1610. The contact fit is used to limit the position of the boss 113 in the groove 1610, thereby limiting the position of the heating pot 11 in the receiving cavity 140. In this embodiment, the cross section of the boss 113 is generally elliptical. The oval-shaped boss 113 can limit the circumferential position of the heating pot 11 in the receiving cavity 140 and prevent the heating pot 11 from rotating in the receiving cavity 140 . Furthermore, the outer surface of the boss 113 and/or the inner surface of the groove 1610 may also be formed with a certain guide slope to facilitate the downward insertion of the boss 113 into the groove 1610 . It is understood that in other embodiments, the cross section of the boss 113 may also be in a square, trapezoidal or other non-circular shape. In other embodiments, the boss 113 may also have a circular cross-section.

The heating element 12 can be disposed on the outer surface of the heating pot 11 to generate heat after being powered on and conduct the heat to the atomization matrix 50 contained in the atomization chamber 110 .

The two electrode parts 122 can be respectively disposed on two opposite sides of the boss 113 along the length direction, so that there is a sufficient separation distance between the two electrode parts 122 to avoid contact between the two electrode parts 122 and avoid short circuit.

Further, each heating track 121 may include a first track 1211 extending along the circumferential direction of the pot body 111 and two second tracks 1212 respectively connected to both ends of the first track 1211. The two second tracks 1212 respectively connect both circumferential ends of the first track 1211 with the two electrode portions 122 . In this embodiment, the first track 1211 may be in the shape of a folded line and extend along the circumferential direction of the pot body 111 , and may be disposed close to the top of the pot body 111 .

The heating pot 11 can be made of dense material with high thermal conductivity, and its thermal conductivity can be greater than 170W/(m.K). The high thermal conductivity of the heating pot 11 enables it to have the advantages of instant heating and efficient heat transfer, and the heat transfer loss can be reduced to less than 5%. The denseness of the heating pot 11 can effectively isolate the substances generated when baking the atomized substrate 50 from contact with the heating element 12, and prevent the substances generated when baking the atomized substrate 50 from penetrating into the heating element 12 and corroding the heating element 12, thus prolonging the heating time.

The structural form of the two electrodes 13 is not limited. For example, they may be electrode wires or electrode pillars. In this embodiment, the two electrodes 13 are electrode wires, and the electrode wires can be made of low resistivity materials, such as silver wires or aluminum wires.

Furthermore, a ventilation gap 141 for air flow can be formed between the outer wall surface of the pot body 111 and the cavity wall surface of the receiving cavity 140, and at least one connecting hole between the ventilation gap 141 and the atomization chamber 110 is formed on the side wall of the pot body 111. A first ventilation hole 1110, and at least one first air inlet hole 1611 for allowing outside air to flow into the ventilation gap 141 is formed on the receiving component 14. The heating element 12 can preheat the airflow that is stagnant or newly enters the ventilation gap 141 . The preheated hot air then enters the atomization chamber 110 through the at least one first ventilation hole 1110 . The atomization substrate 50 is heated to achieve indirect heating of the atomization substrate 50 . The atomization component 10 in this embodiment adopts a hybrid heating form that combines direct heating and indirect heating, thereby integrating smoke generation efficiency and ultimate taste; in addition, compared with the indirect heating form, the aerosol generating device 1. No large-capacity battery is required, which facilitates miniaturization of the device.

Further, the at least one first ventilation hole 1110 may include a plurality of first ventilation holes 1110 , and the plurality of first ventilation holes 1110 may be distributed along the circumferential and/or axial direction of the pot body 111 . In this embodiment, the plurality of first ventilation holes 1110 are evenly spaced along the circumferential direction of the pot body 111 to facilitate the preheated airflow to evenly enter the atomization chamber 110 and achieve uniform heating of the atomization substrate 50 . There may also be a plurality of first air inlets 1611. The plurality of first air inlets 1611 may be formed on the support arm 161 and may be distributed in an array, such as a square array or a circular array evenly distributed. The distribution center line of the air holes 1611 coincides with the center line of the support arm 161 . During suction, the outside air uniformly enters the ventilation gap 141 through the plurality of first air inlet holes 1611, is preheated in the ventilation gap 141, and then flows evenly into the atomization chamber 110, so that the atomization substrate 50 is heated more uniformly.

Furthermore, a second ventilation hole 1130 may be formed on the boss 113 along the longitudinal direction, and a second air inlet hole 1613 corresponding to the second air inlet hole 1130 may be formed on the support arm 161 . The central axis of the second air inlet hole 1613 coincides with the central axis of the second air inlet hole 1130. The air inlet cross-sectional area of the second air inlet hole 1613 and the air inlet cross-sectional area of the second air inlet hole 1130 may or may not be equal. In some embodiments, the air inlet cross-sectional area of the second air inlet hole 1613 may be greater than or equal to the air inlet cross-sectional area of the second air inlet hole 1130 . It can be understood that in other embodiments, the number of the second ventilation holes 1130 and the second air inlet holes 1613 may also be two or more.

In some embodiments, the lower end surface of the support arm 161 can also extend longitudinally downward to form an annular annular protrusion 162 surrounding the plurality of first air inlet holes 1611 and the second air inlet holes 1613 outside. The atomization component 10 can be supported and installed on other components in the aerosol generating device 1 via the annular protrusion 162 . For example, as shown in FIG. 2 , the atomization component 10 can be supported on a support frame installed in the housing 40 via the annular protrusion 162 . 50 on. The annular protrusion 162 can ensure that there is a gap between the lower end surface of the support arm 161 and the upper end surface of the support frame 50 for air flow.

The receiving assembly 14 may include an upper cover 15 and a base 16 that cooperate with each other. The opening 151 and the support arm 161 are located on the upper cover 15 and the base 16 respectively. The receiving cavity 140 may be formed in the upper cover 15 and/or the base 16 . Both the upper cover 15 and the base 16 can be made of low thermal conductivity materials. For example, their thermal conductivity can be less than 2W/(m.K), so as to effectively reduce the heat leakage of the heating pot 11 and the heating element 12, reduce heat loss, and improve heat utilization. , effectively improve the shortcomings of overheating of the aerosol generating device after suction. In some embodiments, the upper cover 15 and the base 16 may be made of low thermal conductivity ceramics, such as diatomaceous earth, cordierite, mullite, etc.

Specifically, in this embodiment, the upper cover 15 is covered on the base 16 , and the receiving cavity 140 may include a first cavity 150 formed in the upper cover 15 and a second cavity 160 formed in the base 16 .

The shape and size of the opening 151 can match the shape and size of the opening 112 . For example, in this embodiment, the opening 151 and the opening 112 are both circular, and the aperture of the opening 151 is consistent with the aperture of the opening 112 . The diameter of the opening 151 is smaller than the outer diameter of the top of the heating pot 11 , so that the periphery of the opening 151 can press against the top wall of the heating pot 11 , thereby achieving axial fixation of the heating pot 11 in the receiving cavity 140 together with the support arm 161 .

The first cavity 150 may be cylindrical, and may extend longitudinally upward from the bottom surface of the upper cover 15 to communicate with the opening 151 . In some embodiments, the first cavity 150 may include a main body section 1501 located at a lower part and a limiting section 1502 located at an upper part. The aperture of the limiting section 1502 is consistent with the outer diameter of the upper end of the heating pot 11 , and the inner surface of the limiting section 1502 contacts and cooperates with the upper outer surface of the heating pot 11 , thereby further enhancing the stability of fixing the heating pot 11 . The aperture of the main section 1501 is consistent with the aperture of the second cavity 160 and is larger than the aperture of the limiting section 1502, so that an annular ring is formed between the inner surfaces of the main section 1501 and the second cavity 160 and the outer surface of the heating pot 11 Ventilation gap 141.

The second cavity 160 may be cylindrical, and may extend longitudinally downward from the top surface of the base 16 . The first cavity 150 and the second cavity 160 are correspondingly connected to form a cylindrical receiving cavity 140 . The cross-sectional shape and size of the base 16 are respectively adapted to the cross-sectional shape and size of the upper cover 15. For example, in this embodiment, the base 16 and the upper cover 15 are both roughly square columnar in shape, so that the atomizer assembly The shape of 10 is also roughly square columnar. It is understood that in other embodiments, the receiving cavity 140 may also be in other shapes such as an elliptical column or a square column.
