The power supply assembly 120 is electrically connected with the heating assembly 130 and is used for supplying power for the heating assembly 130. An aerosol product 200 is arranged in the heating assembly 130, and when the heating assembly 130 is powered on, heat is generated, and the aerosol product 200 in the heating assembly 130 can be heated to generate an aerosol.

[0038] Please refer to Figures 3 to 8 The heating assembly 130 comprises a sleeve 10, a base 20 and a heating element 30. The sleeve 10 has a containing cavity 11, a first opening 12 and a second opening 13 which are communicated with the containing cavity 11, and the first opening 12 and the second opening 13 are arranged at opposite ends of the containing cavity 11 along the axial direction of the sleeve 10. The base 20 is connected to one end of the sleeve 10 which is provided with the second opening 13 and covers the second opening 13. The containing cavity 11 is used for containing the aerosol product 200, and the first opening 12 is used for allowing the aerosol product 200 to pass through and be inserted into the containing cavity 11.

[0039] The base 20 has a heating cavity 21, an air inlet 22 and an air outlet 23. The air inlet 22 is used for communicating the outside with the heating cavity 21, so that the outside air flow can enter the heating cavity 21. The air outlet 23 is communicated with the second opening 13, so that the heating cavity 21 and the containing cavity 11 are communicated, and then the air flow in the heating cavity 21 can enter the containing cavity 11. The heating element 30 is arranged in the base 20 and is used for heating the air flow in the heating cavity 21. The air inlet 22 is communicated with the outside and the heating cavity 21 of the heating assembly 130. In specific implementation, the power supply assembly 120 supplies power for the heating element 30, and the heating element 30 generates heat energy after being powered on, so as to heat the air flow in the heating cavity 21.

[0040] In use, the aerosol product 200 passes through the first opening 12 and is inserted into the containing cavity 11; the cold air flow enters the heating cavity 21 from the air inlet 22, the heating element 30 generates heat energy after being powered on, the cold air flow in the heating cavity 21 is heated to generate hot air flow, the hot air flow enters the containing cavity 11 in sequence through the air outlet 23 and the second opening 13, and then enters the aerosol product 200 in the containing cavity 11, so as to heat the aerosol product 200.

[0041] By arranging the base 20 with the heating cavity 21 and arranging the heating element 30 in the base 20 to heat the air flow in the heating cavity 21, the air flow in the heating cavity 21 can be fully heated, and a sufficient amount of hot air flow can be provided, so that the heating effect on the aerosol product 200 is greatly improved.

[0042] In one embodiment, the base 20 has a first side 24 and a second side 25 oppositely arranged, the first side 24 is connected with the sleeve 10, and the heating element 30 is configured as a heating wire 31, which is arranged on the second side 25. In a specific implementation, the heating wire 31 can be arranged on the second side 25 of the base 20 by a thick film printing process, or can be pre-prepared and then mounted to the second side 25 of the base 20.

[0043] Referring to Figures 3 to 7 , the base 20 includes a first substrate 26, a second substrate 27, and a side plate 28, which enclose a heating cavity 21, wherein the first substrate 26 is connected to the sleeve 10, the second substrate 27 is arranged on the side of the first substrate 26 away from the first opening 12, the side plate 28 is connected between the first substrate 26 and the second substrate 27, and the heating element 30 is arranged on the second substrate 27. That is, the first substrate 26 is located on the first side 24, the second substrate 27 is located on the second side 25, and the heating wire 31 is arranged on the second substrate 27. In a specific implementation, the side plate 28 has a ring structure, and the first substrate 26 and the second substrate 27 both have a planar structure. Connecting the sleeve 10 to the planar first substrate 26 and arranging the heating wire 31 on the planar second substrate 27 makes the operation convenient and fast, which is conducive to the assembly of the heating assembly 130. Of course, in a specific application, as an alternative embodiment, the heating wire 31 can also be arranged on the side plate 28 or on both the second substrate 27 and the side plate 28.

[0044] In one embodiment, the heating wire 31 is arranged on the side of the second substrate 27 away from the heating cavity 21. That is, the heating wire 31 is arranged on the outer side of the second substrate 27, which further improves the convenience of operation. It can be understood that in other embodiments, the heating wire 31 can also be arranged on the side of the second substrate 27 facing the heating cavity 21.

[0045] Referring to Figure 2 , Figure 4 and Figure 6 , the heating wire 31 includes a wire body 311 and two heating end portions 312, the heating end portions 312 are arranged on opposite sides of the second substrate 27, the wire body 311 is connected to the two heating end portions 312 at both ends, and the wire body 311 is arranged in a bent manner. Among them, the two heating end portions 312 are used to connect the power supply pins (not shown), so as to realize the electrical connection between the heating wire 31 and the power supply assembly 120. In a specific implementation, the wire body 311 is arranged in a bent manner, so that the heating wire 31 can cover the entire second substrate 27, thereby increasing the heating area of the second substrate 27, and further enabling the airflow in the heating cavity 21 to be fully heated.

[0046] In an embodiment, the air inlet 22 is formed in the side plate 28, and the air outlet 23 is formed in the first base plate 26. The sleeve 10 is connected to the first base plate 26, and the air outlet 23 is formed in the first base plate 26 so as to be in communication with the second opening 13 of the sleeve 10, thereby enabling the heating cavity 21 and the accommodating cavity 11 to be in communication. Before entering the heating cavity 21, the cold air flow flows along the periphery of the sleeve 10 from the end of the sleeve 10 away from the base 20 to the end of the sleeve 10 close to the base 20. By forming the air inlet 22 in the side plate 28 of the base 20, the flow path of the cold air flow before flowing into the heating cavity 21 is shortened, which is conducive to the cold air flow quickly entering the heating cavity 21. It can be understood that in other embodiments, the air inlet 22 can also be formed in the second base plate 27, or can be formed in the second base plate 27 and the side plate 28 at the same time.

[0047] In an embodiment, the air inlet 22 is formed in the side plate 28, and the air outlet 23 is formed in the first base plate 26. The sleeve 10 is connected to the first base plate 26, and the air outlet 23 is formed in the first base plate 26 so as to be in communication with the second opening 13 of the sleeve 10, thereby enabling the heating cavity 21 and the accommodating cavity 11 to be in communication. Before entering the heating cavity 21, the cold air flow flows along the periphery of the sleeve 10 from the end of the sleeve 10 away from the base 20 to the end of the sleeve 10 close to the base 20. By forming the air inlet 22 in the side plate 28 of the base 20, the flow path of the cold air flow before flowing into the heating cavity 21 is shortened, which is conducive to the cold air flow quickly entering the heating cavity 21. It can be understood that in other embodiments, the air inlet 22 can also be formed in the second base plate 27, or can be formed in the second base plate 27 and the side plate 28 at the same time.

[0048] In an embodiment, the air outlet 23 is formed in the first base plate 26. Specifically, the air outlet 23 is formed on the entire first base plate 26, that is, the air outlet 23 is uniformly distributed on the first base plate 26. In this way, the first base plate 26 functions as a uniform air distribution plate, so that the air flow flows into the accommodating cavity 11 more uniformly, which is conducive to uniformly heating the aerosol product 200.

[0049] In an embodiment, the second base plate 27 is made of insulating ceramic material, and the sleeve 10, the first base plate 26 and the side plate 28 are made of metal material. The heating circuit 31 is arranged on the second base plate 27. The second base plate 27 is made of insulating ceramic material, so that the second base plate 27 has insulation, thereby improving the safety of the heating assembly 130. It should be noted that when the heating circuit 31 is arranged on the side plate 28, the side plate 28 can also be made of insulating ceramic material, or an insulating layer can be coated on the side plate 28.

[0050] In an embodiment, the sleeve 10, the first base plate 26 and the side plate 28 can be integrally formed. In this way, on the one hand, the connection between the sleeve 10 and the base 20 is firm, and on the other hand, the assembly efficiency of the heating assembly 130 is improved.

[0051] Please refer to Figure 2 and Figure 6The base 20 further comprises a support 29 arranged in the heating cavity 21 and supported between the first substrate 26 and the second substrate 27. By arranging the support 29, the first substrate 26 can be supported to avoid being pushed towards the second substrate 27 due to excessive force when the aerosol article 200 is inserted into the accommodation cavity 11, so that the first substrate 26 is easily deformed and the volume of the heating cavity 21 is reduced. In specific implementation, the support 29 can be arranged as a support column, and a plurality of support columns can be arranged and uniformly distributed between the first substrate 26 and the second substrate 27.

[0052] In an embodiment, referring to Figure 7 In an embodiment, the dimension L1 of the heating cavity 21 along the axial direction of the sleeve 10 is less than the dimension L2 of the heating cavity 21 along the radial direction of the sleeve 10. The dimension L1 of the heating cavity 21 along the axial direction of the sleeve 10 can also be understood as the vertical distance between the first substrate 26 and the second substrate 27. The dimension L2 of the heating cavity 21 along the radial direction of the sleeve 10 can also be understood as the length of the line connecting the two most distant points in the cross-sectional shape of the heating cavity 21 perpendicular to the central axis M. For example, when the base 20 is a hollow cylinder and the cross-section of the heating cavity 21 perpendicular to the central axis M is a circle, the dimension L2 of the heating cavity 21 along the radial direction of the sleeve 10 can be understood as the diameter of the circle. Or, when the base 20 is a hollow quadrangular prism and the cross-section of the heating cavity 21 perpendicular to the central axis M is a rectangle, the dimension L2 of the heating cavity 21 along the radial direction of the sleeve 10 can be understood as the length of the diagonal of the rectangle. In this way, the base 20 is flat, the dimension of the base 20 in the axial direction is short, and the heating circuit 31 is arranged on the second substrate 27 at the bottom of the base 20. The heat generated by the heating circuit 31 can be quickly transmitted to the side of the heating cavity 21 close to the first substrate 26 in the axial direction, so that the airflow in the heating cavity 21 can be fully heated.

[0053] In an embodiment, the dimension L1 of the heating cavity 21 along the axial direction of the sleeve 10 is 1.8mm-3.4mm. In specific implementation, the dimension L1 of the heating cavity 21 along the axial direction of the sleeve 10 can be 1.8mm, 2.0mm, 2.2mm, 2.4mm, 2.6mm, 2.8mm, 3.0mm, 3.2mm, 3.4mm, etc.

[0054] In an embodiment, the base 20 is arranged to protrude from the sleeve 10 in a direction perpendicular to the axial direction of the sleeve 10. In this way, the cross-sectional area of the heating cavity 21 perpendicular to the axial direction of the sleeve 10 is greater than the cross-sectional area of the sleeve 10 perpendicular to the axial direction thereof, so that the heating cavity 21 can provide sufficient amount of hot airflow to the accommodation cavity 11. It can be understood that in other embodiments, the base 20 can also be arranged flush with the sleeve 10 in a direction perpendicular to the axial direction of the sleeve 10.

[0055] In an embodiment, the base 20 is a hollow cylindrical structure or a prismatic structure, and the central axis of the accommodating cavity 11 is collinear with the central axis of the heating cavity 21. That is, the accommodating cavity 11 and the heating cavity 21 are coaxially arranged. In this way, the overall structure of the heating assembly 130 is regular, and the installation is facilitated. It should be noted that the central axis of the accommodating cavity 11 and the central axis of the heating cavity 21 are slightly deviated, which can also be regarded as coaxial arrangement. Of course, in other embodiments, the central axis of the accommodating cavity 11 and the central axis of the heating cavity 21 can be arranged in parallel.

[0056] Referring to Figure 2 and Figure 5 The heating assembly 130 further comprises a limiting member 40 connected to the base 20 and / or the sleeve 10 and located in the accommodating cavity 11. The limiting member 40 is used to abut against the end of the aerosol product 200 when the aerosol product 200 is accommodated in the accommodating cavity 11. When the aerosol product 200 abuts against the base 20, the outlet 23 is easily blocked. By arranging the limiting member 40, the end of the aerosol product 200 abuts against the limiting member 40 when the aerosol product 200 is accommodated in the accommodating cavity 11, so that a gap is formed between the aerosol product 200 and the base 20, thereby avoiding the blockage of the outlet 23. In a specific implementation, at least two limiting members 40 can be arranged around the central axis of the sleeve 10.

[0057] Referring to Figure 2 and Figure 9 The atomization device 100 further comprises a fixing assembly 140, and the heating assembly 130 is installed in the fixing assembly 140, and the fixing assembly 140 is installed in the shell 110. The fixing assembly 140 comprises a first sleeve 141, a second sleeve 142 and a base 143. The first sleeve 141 comprises a first cylinder 1411 and a first inwardly-retracted pipe 1412 coaxially arranged, and the first inwardly-retracted pipe 1412 is inwardly retracted from one end or the inside of the first cylinder 1411. The second sleeve 142 comprises a second cylinder 1421 and a second inwardly-retracted pipe 1422 coaxially arranged, and the second inwardly-retracted pipe 1422 is inwardly retracted from one end or the inside of the second cylinder 1421. The first cylinder 1411 is connected to one end of the second cylinder 1421, the first inwardly-retracted pipe 1412 extends into the second cylinder 1421 and extends towards the second inwardly-retracted pipe 1422, and the base 143 is connected to the end of the second cylinder 1421 away from the first cylinder 1411. The end of the sleeve 10 away from the base 20 is connected between the first inwardly-retracted pipe 1412 and the second inwardly-retracted pipe 1422, and the end of the base 20 away from the sleeve 10 is connected to the base 143. The heating assembly 130 is located in the second cylinder 1421 and is spaced apart from the inner surface of the second cylinder 1421. The cold air flows through the space between the heating assembly 130 and the second cylinder 1421 to the air inlet 22, and then flows into the heating cavity 21.

[0058] In an embodiment, the inner surface of the second barrel 1421 is provided with a reflective heat insulation layer (not shown in the figure). By providing the reflective heat insulation layer, the heat radiation of the heating assembly 130 can be reflected, reducing heat loss.

[0059] The above describes the present application by using specific examples, which is only used to help understand the present application, and does not limit the present application. For those skilled in the art to which the present application belongs, according to the idea of the present application, a number of simple deductions, deformations or substitutions can be made.
