The tightening structure is used to clamp and compress the aerosol product in the atomization cavity.

[0007] In one embodiment, the atomization tube includes a first tube body and a second tube body arranged in sequence along its axial direction;

[0008] The inner cavity of the first tube body is a first cavity, and the inner cavity of the second tube body is a second cavity. The first cavity is communicated with the second cavity to jointly form the atomization cavity; the first opening is formed at one end of the first tube body away from the second tube body, and the second opening is formed at one end of the second tube body away from the first tube body; the first cavity is for the aerosol product to be inserted, and the second cavity is for accommodating the heating component;

[0009] At least a part of the first tube body forms the tightening structure, or the tightening structure is arranged in the first tube body.

[0010] In one embodiment, the inner diameter of the first tube body gradually decreases in a direction approaching the second tube body, so that the first tube body forms the tightening structure.

[0011] In one embodiment, the thickness of the wall of the first tube body remains unchanged, and the wall is inclined, so that both the inner diameter and the outer diameter of the first tube body gradually decrease in a direction approaching the second tube body; or,

[0012] The outer diameters of the first tube bodies are the same, and the thickness of the wall of the first tube body gradually increases, so that the inner diameter of the first tube body gradually decreases in a direction approaching the second tube body.

[0013] In one embodiment, the first tube body includes a first tube section and a second tube section arranged in sequence along its axial direction, and the second tube section is connected between the first tube section and the second tube body; the inner diameter sizes of the first tube sections are the same, and the inner diameter of the second tube section gradually decreases in a direction approaching the second tube body, so that the second tube section forms the tightening structure.

[0014] In one embodiment, the tightening structure includes a plurality of protruding portions, and the plurality of protruding portions are arranged at intervals along the circumferential direction of the first tube body inside the first tube body and are connected to the inner surface of the first tube body; the protruding portions extend obliquely in a direction gradually approaching the central axis of the first tube body from one end far from the second tube body to one end close to the second tube body.

[0015] In one embodiment, the tightening structure has an inclined side for facing the aerosol product in any cross-section in the axial direction of the atomizing tube;

And the "connection" and "coupling" mentioned in the present application, unless otherwise specified, both include direct and indirect connection (coupling).

[0033] Please refer to Figure 1 and Figure 2 , an embodiment of the present utility model provides an atomizing device 103 and an atomizing device 100. The atomizing device 100 includes a housing 101, a power supply assembly 102, and an atomizing device 103. The power supply assembly 102 and the atomizing device 100 are both disposed in the housing 101, and the power supply assembly 102 is used to supply power to the atomizing device 103. After the atomizing device 103 is powered on, it can heat the aerosol product 200 placed therein to generate an aerosol.

[0034] Please refer to Figure 2 and Figure 3, the atomization device 103 includes an atomization tube 10 and a heating component 20. The atomization tube 10 is provided with an atomization cavity 11, a first opening 12, and a second opening 13. The first opening 12 and the second opening 13 are located at opposite ends of the atomization tube 10, and both the first opening 12 and the second opening 13 communicate the atomization cavity 11 with the outside. The first opening 12 is for an aerosol product 200 to be inserted into the atomization cavity 11. The heating component 20 is connected to the second opening 13, and the heating component 20 is configured to heat the airflow flowing towards the aerosol product 200, so that the aerosol product 200 generates aerosol under the heating of the hot airflow. Specifically, the heating component 20 heats the airflow flowing towards the aerosol product 200 to form a hot airflow, and the hot airflow flows into the aerosol product 200 to heat the aerosol product 200.

[0035] The heating component 20 is arranged to be connected to the second opening 13 so that the airflow can flow into the atomization cavity 11 through the heating component 20. When the airflow passes through the heating component 20, it is heated to form a hot airflow. The hot airflow flows out of the heating component 20 and into the atomization cavity 11, and then can heat the aerosol product 200 located in the atomization cavity 11. In specific implementation, the heating component 20 can be placed at the second opening 13, or partially or completely embedded in the second opening 13.

[0036] In one embodiment, the atomization tube 10 is a component made of a heat-conducting material and is used to assist in heating the periphery of the aerosol product 200. By making the atomization tube 10 of a heat-conducting material, it can conduct heat. Since the aerosol product 200 is inserted into the atomization tube 10 and the atomization tube 10 is disposed around the periphery of the aerosol product 200, the periphery of the aerosol product 200 can be heated, playing a role in assisting heating. Therefore, the atomization device 103 provided in this embodiment heats the aerosol product 200 both by the airflow heating method and by the peripheral heating method, greatly improving the heating efficiency of the aerosol product 200. It can be understood that in other embodiments, the atomization tube 10 can also be made of a non-heat-conducting material.

[0037] In one embodiment, at least a part of the atomization tube 10 has a tightening structure 30. The inner diameter of the tightening structure 30 gradually decreases in the direction from the first opening 12 towards the second opening 13. The tightening structure 30 is used to clamp and compress the aerosol product 200 in the atomization cavity 11. That is to say, from the end far from the second opening 13 to the end close to the second opening 13, the inner diameter of the tightening structure 30 gradually decreases. When the aerosol product 200 is inserted into the atomization cavity 11, the tightening structure 30 clamps the aerosol product 200 and compresses the end of the aerosol product 200 facing the second opening 13, so that the degree of aggregation of the end of the aerosol product 200 facing the second opening 13 increases and becomes more concentrated.

[0038] By clamping the tightening structure 30, the stability of the aerosol article 200 located in the atomization chamber 11 can be increased, thereby preventing the aerosol article 200 from shaking. By compressing one end of the aerosol article 200 facing the second opening 13 by the tightening structure 30, this part becomes more concentrated. As the hot air flow increases with the flowing distance, its energy gradually decreases. When the hot air flow heated by the heating component 20 flows towards the aerosol article 200, it first reaches one end of the aerosol article 200 facing the second opening 13. Therefore, the energy of the hot air flow at one end of the aerosol article 200 facing the second opening 13 is higher than that at other parts of the aerosol article 200. By setting the tightening structure 30 to make one end of the aerosol article 200 facing the second opening 13 more concentrated, this part can fully absorb the energy of the hot air flow, which can greatly accelerate the generation speed of the aerosol.

[0039] In addition, the inner diameter of the tightening structure 30 gradually decreases along the direction from the first opening 12 towards the second opening 13. That is to say, the inner diameter of the tightening structure 30 gradually expands along the direction close to the first opening 12. The hot air flow flows from one end close to the second opening 13 towards one end close to the first opening 12, and its flowing direction in the aerosol article 200 completely conforms to the slope direction of the inner wall of the tightening structure 30. In this way, the heating efficiency of the hot air flow can be improved.

[0040] Please refer to Figure 2 and Figure 3 , the atomization tube 10 includes a first tube body 14 and a second tube body 15 arranged in sequence along its axial direction. The inner cavity of the first tube body 14 is the first cavity 141, and the inner cavity of the second tube body 15 is the second cavity 151. The first cavity 141 is communicated with the second cavity 151 to jointly form the atomization chamber 11. The first opening 12 is formed at one end of the first tube body 14 away from the second tube body 15, and the second opening 13 is formed at one end of the second tube body 15 away from the first tube body 14. The first cavity 141 is used for inserting the aerosol article 200, and the second cavity 151 is used for accommodating the heating component 20. Among them, the heating component 20 can be completely accommodated in the second cavity 151, or partially located in the second cavity 151 and partially extend out of the second cavity 151. With such a setting, the atomization tube 10 can be used for inserting the aerosol article 200 and for installing the heating component 20. One end of the heating component 20 away from the first tube body 14 can be suspended, which is beneficial to the setting of the air intake channel.

[0041] It can be understood that in other embodiments, the atomization tube 10 includes the first tube body 14, and it is also possible not to provide the second tube body 15. When adopting this implementation scheme, the cavity of the first tube body 14 forms the atomization chamber 11, one end opening of the first tube body 14 forms the first opening 12, and the other end opening forms the second opening 13.

[0042] Since the aerosol article 200 is inserted into the first cavity 141 of the first tube body 14, in order to facilitate the tightening structure 30 to clamp and compress the aerosol article 200, at least part of the first tube body 14 can be formed into the tightening structure 30, or the tightening structure 30 can be arranged in the first tube body 14.

[0043] Please refer to Figure 2 and Figure 3 , in an embodiment, the inner diameter of the first tube body 14 gradually decreases in the direction close to the second tube body 15, so that the first tube body 14 forms a tightening structure 30. Specifically, when the aerosol article 200 is inserted into the first cavity 141 of the first tube body 14, along with the gradual decrease of the inner diameter of the first tube body 14, the aerosol article 200 is clamped tighter and tighter by the first tube body 14, and one end of the aerosol article 200 facing the second opening 13 is compressed by the inner wall of the first tube body 14, so that one end of the aerosol article 200 facing the second opening 13 is more concentrated. The air flow enters the first tube body 14 after being heated by the heating component 20 located in the second tube body 15, and first reaches the compressed part of the aerosol article 200, so that the aerosol article 200 can fully absorb the energy of the hot air flow and accelerate the aerosol generation speed.

[0044] Please refer to Figure 2 and Figure 4 , in an embodiment, the thickness of the tube wall of the first tube body 14 remains unchanged, and the tube wall is inclined, so that both the inner diameter and the outer diameter of the first tube body 14 gradually decrease in the direction close to the second tube body 15. Compared with the technical solution in which the thickness of the tube wall of the first tube body 14 increases, the thickness of the tube wall of the first tube body 14 remains unchanged, so that the overall material used for the first tube body 14 is less, and the heat absorbed by itself is less, that is, more heat can be used to heat the aerosol article 200, improving the utilization rate of heat and reducing heat loss. Of course, please refer to Figure 3 , in other embodiments, the outer diameter of the first tube body 14 can also be set to be the same, and the thickness of the tube wall of the first tube body 14 gradually increases, so that the inner diameter of the first tube body 14 gradually decreases in the direction close to the second tube body 15.

[0045] Please refer to Figure 2 and Figure 5, in another embodiment, the first tube body 14 includes a first tube section 142 and a second tube section 143 arranged in sequence along its axial direction. The second tube section 143 is connected between the first tube section 142 and the second tube body 15. The inner diameter of the first tube section 142 is the same, and the inner diameter of the second tube section 143 gradually decreases in the direction close to the second tube body 15, so that the second tube section 143 forms a tightening structure 30. Specifically, when the aerosol article 200 passes through the first tube section 142 and enters the second tube section 143, as the inner diameter of the second tube section 143 gradually decreases, the aerosol article 200 is clamped tighter and tighter by the second tube section 143. Moreover, one end of the aerosol article 200 facing the second opening 13 is compressed by the inner wall of the second tube section 143, so that one end of the aerosol article 200 facing the second opening 13 is more concentrated. The air flow is heated by the heating component 20 located in the second tube body 15 and then enters the second tube section 143, and first reaches the compressed part of the aerosol article 200, so that the aerosol article 200 can fully absorb the energy of the hot air flow and accelerate the aerosol generation speed.

[0046] Please refer to Figure 6 , in another embodiment, the tightening structure 30 is arranged in the first tube body 14. The tightening structure 30 includes a plurality of protruding parts 31. The plurality of protruding parts 31 are arranged at intervals along the circumferential direction of the first tube body 14 in the first tube body 14 and are connected to the inner surface of the first tube body 14. The protruding part 31 extends obliquely in the direction gradually approaching the central axis M of the first tube body 14 from the end far from the second tube body 15 to the end close to the second tube body 15.

[0047] Specifically, when the aerosol article 200 is inserted into the first tube body 14, as the protruding part 31 gradually approaches the central axis M of the first tube body 14, that is, the inner side of the protruding part 31 gradually approaches the central axis M of the first tube body 14, the aerosol article 200 is clamped tighter and tighter by the protruding part 31. Moreover, one end of the aerosol article 200 facing the second opening 13 is compressed by the inner side of the protruding part 31, so that one end of the aerosol article 200 facing the second opening 13 is more concentrated. The air flow is heated by the heating component 20 located in the second tube body 15 and then enters the first tube body 14, and first reaches the compressed part of the aerosol article 200, so that the aerosol article 200 can fully absorb the energy of the hot air flow and accelerate the aerosol generation speed.

[0048] In one embodiment, the tightening structure 30 has an inclined side 32 for facing the aerosol article 200 in any cross-section in the axial direction of the atomizing tube 10. The distance between the inclined side 32 and the central axis M of the first tube body 14 gradually decreases in the direction close to the second opening 13, and the included angle α between the inclined side 32 and the central axis M of the first tube body 14 is 10° to 60°. The inclined side 32 is the inner side of the tightening structure. With such a setting, the inner wall of the tightening structure 30 is inclined and will not be overly inclined. Thus, on the one hand, the tightening structure 30 can clamp and compress the aerosol article 200, and on the other hand, it can prevent the aerosol article 200 from being overly compressed and being difficult to take out from the atomizing tube 10. Preferably, the included angle α is 45°.

[0049] Please refer to Figure 2 and Figure 3 , a first bearing step 16 is provided in the atomizing tube 10, and the first bearing step 16 is used to abut against the end of the aerosol article 200 inserted into the atomizing cavity 11. Specifically, a first bearing step 16 is provided at one end of the first tube body 14 close to the second tube body 15. When the aerosol article 200 is inserted into the first cavity 141 and touches the first bearing step 16, the insertion action can be stopped, so that the aerosol article 200 abuts against the first bearing step 16 to prevent the aerosol article 200 from being overly inserted into the second cavity 151.

[0050] Please refer to Figure 2 and Figure 3 , a second bearing step 17 is provided in the atomizing tube 10, and the second bearing step 17 is used to abut against the heating assembly 20. Specifically, a second bearing step 17 is provided at one end of the second tube body 15 close to the first tube body 14. When the heating assembly 20 is placed in the second cavity 151, it abuts against the second bearing step 17.

[0051] Please refer to Figure 2 , Figure 3 and Figure 7 , the heating assembly 20 includes a heating element 21 and a heat exchange core 22. The heat exchange core 22 is installed on the second bearing step 17 and has a plurality of air guide holes 221 communicating with the first cavity 141. The heating element 21 is disposed around the circumference of the heat exchange core 22 and is used to generate heat. In a specific implementation, the air flow passes through the air guide holes 221 of the heat exchange core 22 and flows towards the aerosol article 200 located in the first cavity 141. When the heating element 21 is powered on, it generates heat, and the heat is transferred to the heat exchange core 22. The heat exchange core 22 can heat the flowing air to form a hot air flow, and the hot air flow flows towards the aerosol article 200 to realize the heating of the aerosol article 200. In this embodiment, the heating element 21 generates heat by means of resistance heating. It can be understood that in other embodiments, the heating element 21 can also generate heat by other means, such as electromagnetic induction heating.

[0052] Please refer toFigure 2 and Figure 7 Moreover, the heating assembly 20 further includes two pins 23. One end of each pin 23 is connected to the heating element 21, and the other end of each pin 23 is used to connect to the power supply assembly 102. By providing the pins 23, the electrical connection between the heating element 21 and the power supply assembly 102 is achieved.

[0053] Please refer to Figure 2 and Figure 3 and, the atomizing device 103 further includes a first sleeve 40, a second sleeve 50, and a base 60. The first sleeve 40 and the second sleeve 50 are arranged in sequence along the axial direction. The base 60 is disposed at one end of the second sleeve 50 away from the first sleeve 40. The base 60, the first sleeve 40, and the second sleeve 50 enclose a receiving space 70, and the atomizing tube 10, the heat exchange core 22, and the heating element 21 are all received in the receiving space 70. Wherein, the first sleeve 40 and the second sleeve 50 play a heat insulation role for the atomizing tube 10.

[0054] In the atomizing device 103 and the atomizing equipment 100 provided by the embodiments of the present invention, since at least a part of the atomizing tube 10 is provided with a tightening structure 30 for clamping the aerosol article 200 in the atomizing chamber 11 and compressing one end of the aerosol article 200 facing the second opening 13, when the aerosol article 200 is placed in the atomizing tube 10, the stability is improved, and the degree of aggregation of the end of the aerosol article 200 facing the second opening 13 is increased and more concentrated, so that this part can fully absorb the energy of the hot air flow.

[0055] The above uses specific examples to elaborate on the present invention, which is only used to help understand the present invention and is not intended to limit the present invention. For those skilled in the technical field to which the present invention belongs, according to the idea of the present invention, several simple deductions, deformations or substitutions can also be made.
