Description

Technical Field

[0001] This utility model relates to the field of aerosol generation technology, and in particular to an aerosol delivery device. Background Technology

[0002] Currently, aerosol generating devices can heat non-combustible products (such as non-combustible tobacco products) at relatively low temperatures (e.g., 250℃~500℃), thereby causing the heated non-combustible products to release tobacco-flavored aerosols that are delivered to consumers without combustion, thus replacing combustible tobacco products. In existing technologies, the heating element is mounted on a support frame. To ensure the stable installation of the heating element, a relatively complex assembly method is required, which reduces the assembly efficiency of the heating element. Summary of the Invention

[0003] To overcome the problems of low assembly efficiency of heating elements in existing aerosol generation devices, this utility model provides an aerosol delivery device.

[0004] In view of the above technical problems, this utility model provides an aerosol delivery device, comprising:

[0005] A first fixed tube has a first receiving cavity for receiving at least a portion of a heat-resistant non-combustible article;

[0006] The second fixing tube is detachably connected to the first fixing tube and connected to the first fixing tube to form a second receiving cavity. In the axial direction of the aerosol delivery device, the first receiving cavity and the second receiving cavity are arranged adjacent to each other.

[0007] The heater is fixed in the second receiving cavity. The diameter of the end of the first fixing tube near the second fixing tube is larger than the diameter of the end of the first fixing tube away from the second fixing tube. The heater is interference-fitted with the end of the first fixing tube away from the second fixing tube.

[0008] In the above embodiments of this utility model, the first fixing tube and the second fixing tube are detachably connected. At the same time, the diameter of the end of the first fixing tube near the second fixing tube is larger than the diameter of the end of the first fixing tube away from the second fixing tube. This allows the heater to be gradually inserted from the end of the second fixing tube away from the first fixing tube during assembly. After entering the second receiving cavity, it is stably fixed in the second receiving cavity by interference fit with the end of the first fixing tube away from the second fixing tube. This improves the assembly efficiency of the heater while ensuring stable installation. Attached Figure Description

Detailed Implementation

[0015] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0016] like Figures 1 to 3 As shown, one embodiment of this utility model provides an aerosol delivery device, comprising:

[0017] The first fixed tube 300 has a first receiving cavity 310 for receiving at least a portion of the heat-non-combustible article 200.

[0018] The second fixing tube 400 is detachably connected to the first fixing tube 300 and connected to the first fixing tube 300 to form a second receiving cavity 320. In the direction of axis a of the aerosol delivery device, the first receiving cavity 310 and the second receiving cavity 320 are arranged adjacent to each other.

[0019] The heater 500 is fixed in the second receiving cavity 320. The diameter of the end of the first fixing tube 300 near the second fixing tube 400 is larger than the diameter of the end of the first fixing tube 300 away from the second fixing tube 400. The heater 500 is interference-fitted with the end of the first fixing tube 300 away from the second fixing tube 400.

[0020] In this embodiment, the first fixing tube 300 and the second fixing tube 400 are detachably connected. At the same time, the diameter of the end of the first fixing tube 300 near the second fixing tube 400 is larger than the diameter of the end of the first fixing tube 300 away from the second fixing tube 400. This allows the heater 500 to be inserted from the end of the second fixing tube 400 away from the first fixing tube 300 during assembly. After entering the second receiving cavity 320, it is stably fixed in the second receiving cavity 320 by interference fit with the end of the first fixing tube 300 away from the second fixing tube 400. This improves the assembly efficiency of the heater while ensuring the stable installation of the heater 500.

[0021] like Figure 2 and Figure 3 As shown, in one embodiment, the second fixing tube 400 and the first fixing tube 300 are connected by a snap-fit ​​connection, which improves the installation and disassembly speed between the second fixing tube 400 and the first fixing tube 300 and improves the assembly efficiency of the aerosol delivery device.

[0022] like Figure 2 and Figure 3 As shown, in one embodiment, a boss 420 is provided on the inner sidewall of the second fixing tube 400, and the end of the heater 500 away from the first fixing tube 300 abuts against the boss 420. It can be understood that the boss 420 is used to abut against the end of the heater 500 away from the first fixing tube 300 after an interference fit with the end of the first fixing tube 300 away from the second fixing tube 400, thereby further improving the stability of the heater 500 installation. The position of the boss 420 can be set according to the length of the heater 500, thereby ensuring that the heater 500 can abut against the boss 420 after an interference fit with the end of the first fixing tube 300 away from the second fixing tube 400.

[0023] In this embodiment, during assembly, the heater 500 can first be inserted into the first fixing tube 300 and press-fitted with the end of the first fixing tube 300 away from the second fixing tube 400. Then, the second fixing tube 400 is connected to the first fixing tube 300, and the end of the heater 500 away from the first fixing tube 300 is abutted against the boss 420, thereby completing the assembly of the heater 500. This improves the assembly efficiency of the heater 500 and further enhances the stability of the heater 500 installation.

[0024] like Figure 2 and Figure 3As shown, in one embodiment, a limiting ring 330 is provided on the inner sidewall of the first fixing tube 300, and the end of the heater 500 away from the second fixing tube 400 abuts against the limiting ring 330. The first receiving cavity 310 is located at the upper end of the limiting ring 330, and the second receiving cavity 320 is located at the lower end of the limiting ring 330.

[0025] Understandably, the limiting ring 330 has a certain thickness to prevent the heat-not-burning product 200 from directly contacting the heater 500 after being inserted into the first receiving cavity 310. This allows the heater 500 to evenly transfer heat to the heat-not-burning product 200, thereby improving heating efficiency. Simultaneously, it can also align with the end of the heat-not-burning product 200 inserted into the first receiving cavity 310, ensuring that the air heated by the heater 500 enters the heat-not-burning product 200 through the inner ring of the limiting ring 330. This concentrates heating on the central part of the heat-not-burning product 200, preventing excessively high temperatures at the periphery and thus avoiding discoloration.

[0026] like Figure 2 and Figure 3 As shown, in one embodiment, the inner diameter of the connection between the first fixing tube 300 and the second fixing tube is matched and both are larger than the outer diameter of the heater 500, thereby forming a first air passage 700 surrounding the outer wall of the heater 500 between the heater 500 and the first fixing tube 300 and the second fixing tube.

[0027] Understandably, the first air passage 700 is arranged around the outer wall of the heater 500, which allows the gas flowing through the first air passage 700 to circulate around the heater 500, thereby removing heat from the outer periphery of the heater 500.

[0028] like Figure 2 and Figure 3 As shown, in some embodiments, the second fixed tube 400 has a connecting channel 410 that connects to the first air passage 700, and the heater 500 has a connecting hole 512 that connects to the first air passage 700. Gas in the first air passage 700 enters the heater 500 through the connecting hole 512.

[0029] In some embodiments, the air intake direction of the connecting hole 512 is perpendicular to the air intake direction of the connecting channel 410, thereby preventing air from flowing directly from the connecting channel 410 into the connecting hole 512 without fully flowing through the first air passage 700, that is, through the outer wall of the heater 500, so that more air in the first air passage 700 can flow through the outer wall of the heater 500, thus improving the heat utilization rate.

[0030] In some embodiments, the axial orthographic projection of the connecting hole 512 is located on the inner sidewall of the first fixed tube 300 and overlaps with the first air passage 700, thereby ensuring that air flows relatively completely through the first air passage 700 before flowing into the connecting hole 512, so that the air can be heated by the outer sidewall of the heater 500 in the first air passage 700.

[0031] like Figure 2 and Figure 3 As shown, in some embodiments, the aerosol delivery device further includes a heat insulation tube 100, which is provided with an insertion port 110 for inserting the heated non-combustible article 200 and a first air inlet 120 for connecting to the outside air.

[0032] Along axis a of the aerosol delivery device, the insertion port 110 is disposed adjacent to the first receiving cavity 310. The end of the first fixing tube 300 away from the second fixing tube 400 and the end of the second fixing tube 400 away from the first fixing tube 300 respectively abut against the opposite ends of the heat insulation tube 100. The heat insulation tube 100, the first fixing tube 300 and the second fixing tube 400 together form a second air passage 600 that connects to the first air inlet 120. The second air passage 600 is connected to the first air passage 700 through the connecting channel 410.

[0033] Understandably, in the direction of axis a of the aerosol delivery device, the insertion port 110 is disposed adjacent to the first receiving cavity 310, so that the heat-not-burning article 200 can be inserted into the first receiving cavity 310 through the insertion port 110. After the first fixing tube 300 and the second fixing tube 400 are connected, they together form an outer wall with an outer diameter of approximately equal, and then form the second air passage 600 between it and the inner wall of the heat insulation tube 100.

[0034] In this embodiment, gas enters the heater 500 sequentially through the first air inlet 120, the second air passage 600, the connecting channel 410, the first air passage 700, and the connecting hole 512. After being heated by the heater 500, the gas enters the heat-resistant non-combustible product 200 inserted into the first receiving cavity 310, thereby heating the aerosol in the heat-resistant non-combustible product 200.

[0035] In one embodiment, the thermal conductivity of the second fixing tube 400 is less than that of the first fixing tube 300, thereby allowing more heat from the heater 500 to be directed to the first fixing tube 300. This enables more heat to be used to heat the heat-resistant non-combustible product 200 in the first receiving cavity 310 within the first fixing tube 300, avoiding heat waste and improving heat utilization. The first fixing tube 300 can be made of a high-thermal-conductivity material with a temperature resistance of 200 degrees Celsius or higher. The second fixing tube 400 can be made of a low-thermal-conductivity material with a temperature resistance of 200 degrees Celsius or higher. In some embodiments, the thermal conductivity of the first fixing tube 300 is greater than or equal to 20 W / m*K. The thermal conductivity of the second fixing tube 400 is less than 20 W / m*K. In other embodiments, the thermal conductivity of the first fixing tube 300 and the second fixing tube 400 can be set according to actual conditions, as long as the thermal conductivity of the first fixing tube 300 is greater than that of the second fixing tube 400, so that more heat from the heater 500 is directed to the first fixing tube 300.

[0036] In some embodiments, such as Figure 2 and Figure 3 As shown, the heater 500 is further provided with an air outlet 513 communicating with the first receiving cavity 310, and a heating cavity 511 communicating between the air outlet 513 and the communicating hole 512 and used to heat air to bake the heated non-combustible product 200. Gas enters the heating cavity 511 communicating with the communicating hole 512 through the communicating hole 512, and after being heated in the heating cavity 511, it enters the heated non-combustible product 200 inserted into the first receiving cavity 310.

[0037] In one embodiment, such as Figures 1 to 3 As shown, the aerosol delivery device further includes a housing 900 and a power supply 930 disposed within the housing 900 for supplying energy to the heater 500. The housing 900 has an opening 910 for inserting the heated non-combustible article 200 and a second air inlet 920 connected to the first air inlet 120. Understandably, the housing 900 prevents dust or debris from entering the interior and is also designed for user grip, preventing the aerosol delivery device from becoming too hot to handle during use. The housing 900 is located outside the heat insulation tube 100, and the second air inlet 920 communicates with the first air inlet 120, thereby ensuring that outside air can enter the first air inlet 120.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
