[0058] Please refer to Figure 1 , Figure 1 Schematic diagram of the electrical connection structure of the electronic smoking device according to an embodiment of the present application.

[0059] An electronic smoking device 1000 according to an embodiment of the present application includes a battery module 100 , a control and drive module 200 and a heating module 300 .

[0060] The battery module 100 is electrically connected to the control and drive module 200. The control and drive module 200 is electrically connected to the heating module 300. The battery module 100 supplies power to the control and drive module 200 and the heating module 300. The control and drive module 200 controls the heating module 300 to heat the air entering the heating module 300, and the hot air bakes the smoke-generating medium, so that the smoke-generating medium is atomized into smoke for the user to inhale. The smoke-generating medium may be tobacco, a cigarette cartridge, a cigarette oil, and a cigarette stick.

[0061] For details, please refer to Figures 2 to 4 The heating module 300 of this embodiment includes a base 10 , a sleeve 20 , a first heating component 30 , a partition tube 40 , a connector 50 , and a second heating component 60 . In addition, the electronic smoking device 1000 also includes a housing 70 and a cover 80 .

[0062] The sleeve 20 is fixedly disposed on the base 10. The sleeve 20 includes a first accommodating cavity 20a and a second accommodating cavity 20b. The first accommodating cavity 20a communicates with the second accommodating cavity 20b. The second accommodating cavity 20b is located at an end of the first accommodating cavity 20a away from the base 10.

[0063] The first heating component 30 is fixedly disposed in the first accommodating cavity 20 a , and the first heating component 30 is fixedly connected to the base 10 .

[0064] The partition tube 40 is disposed on the first heating assembly 30 and is located in the second accommodating chamber 20 b.

[0065] The connecting member 50 is fixedly disposed on the partition tube 40. The connecting member 50 is fixedly disposed in the second accommodating chamber 20b.

[0066] The second heating assembly 60 is disposed on the partition tube 40. Specifically, the second heating assembly 60 is detachably disposed on the partition tube 40 through the connecting member 50; that is, the connecting member 50 connects the partition tube 40 and the second heating assembly 60 respectively. The second heating assembly 60 is located in the second accommodating chamber 20b. Optionally, the second heating assembly 60 may be completely located in the second accommodating chamber 20b, or may be partially located in the second accommodating chamber 20b, which is not limited in this embodiment.

[0067] The housing 70 is fixedly disposed on the base 10 and sleeved on the outer circumference of the sleeve 20 .

[0068] The cover 80 is fixedly disposed on the housing 70 and the second heating assembly 60. One end of the cover 80 facing the sleeve 20 is fixedly connected to the second heating assembly 60. The cover 80 is provided with an opening 81 for placing the smoke-generating medium.

[0069] The inner side of the partition tube 40 and the inner side of the second heating assembly 60 define a placement chamber M, and the placement chamber M is used to place the smoke-generating medium. The opening 81 is in communication with the placement chamber M.

[0070] The electronic cigarette device 1000 of this embodiment uses the first heating component 30 to heat the incoming external air, so that the hot air first diffuses to the lower part of the placement chamber M to heat the lower part of the smoke-generating medium first; at the same time, the second heating component 60 is used to heat the smoke-generating medium located in the upper part or / and the middle part of the placement chamber M. This embodiment uses two heating components, namely the first heating component 30 and the second heating component 60, to heat the smoke-generating medium in sections, thereby improving the preheating efficiency and uniformity, and also improving the efficiency and uniformity of heating the smoke-generating medium during the smoking stage, thereby improving the smoke taste.

[0071] For example, when the electronic cigarette device 1000 is in the preheating stage, the first heating component 30 heats the air entering the first heating component 30 to form hot air, and the hot air rises and enters the lower part of the placement cavity M and gradually diffuses to the upper part of the placement cavity M. However, the diffusion process of the hot air requires a certain amount of time, and because the first heating component 30 is close to the lower part of the placement cavity M, the air temperature in the upper part of the placement cavity M is always lower than the air temperature in the lower part of the placement cavity M. At this time, the overall temperature of the air in the placement cavity M will be uneven.

[0072] The second heating assembly 60 is arranged at the upper part of the placement chamber M through the partition tube 40. At this time, when the first heating assembly 30 starts to heat the air, the second heating assembly 60 also starts to heat the air at the upper part of the placement chamber M. In other words, the first heating assembly 30 diffuses the hot air into the lower part of the placement chamber M and continues to diffuse to the upper part of the placement chamber M; the second heating assembly 60 heats the air at the upper part of the placement chamber M into hot air, and the hot air gradually diffuses to the lower part of the placement chamber M. In this way, arranging the heating assemblies at both ends of the placement chamber M not only improves the heating efficiency in the preheating stage, but also improves the uniformity of heating the air.

[0073] Of course, when the electronic smoking device 1000 is in the smoking stage, the arrangement of the first heating component 30 and the second heating component 60 also improves the heating efficiency of the smoke-generating medium in the smoking stage, and improves the uniformity of heating the smoke-generating medium. Its working principle is similar to that in the preheating stage, and will not be repeated here.

[0074] Please refer to Figure 5 and Figure 6 In the heating module 300 of the electronic smoking device 1000 of the present embodiment, the first heating component 30 includes a housing 31 , a first heating element 32 , a first heating member 33 and a first temperature sensing member 34 .

The shell 31 includes a convex ring 311 arranged at an end of the shell 31 away from the base 10 and a spacer column 312 arranged at an end close to the base 10. The lower part of the spacer column 312 is plugged into the base 10, and the upper part of the spacer column 312 separates the base 10 and the shell 31, so that there is a gap between the base 10 and the shell 31, air can flow, and the internal space of the shell 31 is connected through the opening 313 at the bottom of the shell 31.

[0076] The first heating element 32 is fixedly disposed in the housing 31. A recessed portion 321 is provided at one end of the first heating element 32 facing the base 10. At least one through groove 322 is provided on the outer peripheral side of the first heating element 32, and the extension direction of the through groove 322 is consistent with the extension direction of the first heating element 32. In addition, a groove 323 is also provided in the middle of the outer peripheral side of the first heating element 32.

[0077] The groove 323 is disposed between two adjacent through grooves 322 and communicates with the two adjacent through grooves 322. Optionally, in some embodiments, the groove 323 may also be disposed between the through groove 322 and the recessed portion 321, and the groove 323 communicates with the through groove 322 and is isolated from the recessed portion 321.

[0078] Optionally, the first heating element 32 is formed by ceramic sintering. Specifically, the first heating element 32 can be one or a mixture of a silicon dioxide sintered body, an aluminum oxide sintered body, a silicon nitride sintered body, a zirconium oxide sintered body or a silicon carbide material sintered body. The first heating element 32 is made of ceramic material. On the one hand, it has high thermal conductivity, fast heat conduction speed and small specific heat capacity, and less heat loss during heating; on the other hand, it has stable performance at high temperature, does not undergo chemical reactions such as decomposition to produce harmful substances and odors, and has poor oil absorption and will not combine with tobacco oil to produce odor. Of course, the first heating element 32 can also be made of other materials, and this application is not limited.

[0079] The first heating element 33 is arranged in the recessed portion 321, and is used to heat the first heating element 32. The first heating element 33 is electrically connected to the control driving module 200. The first heating element 33 can be a heating resistor or a heating sheet. The first heating element 33 is arranged in the central axis direction of the first heating element 32, so that the first heating element 33 heats the first heating element 32 uniformly.

[0080] The first temperature sensing element 34 is disposed on the first heating element 32, and is used to sense the temperature of the first heating element 32. The first temperature sensing element 34 is electrically connected to the control driving module 200. Specifically, the first temperature sensing element 34 is disposed in the groove 323. The first temperature sensing element 34 is disposed in the center of the first heating element 32, so as to accurately sense the temperature of the first heating element 32.

[0081] Optionally, the first temperature sensing element 34 may be a thermocouple or other device for sensing temperature.

[0082] In this embodiment, the heating module 300 detects the temperature of the first heating element 32 through the first temperature sensing element 34, and compares the real-time temperature with the target set temperature in the control driving module 200 to control the temperature of the first heating element 32, so as to ensure that the temperature of the hot air of the first heating element 32 is controlled between 220 degrees Celsius and 280 degrees Celsius, thereby ensuring a comfortable taste of the smoking medium. Of course, the temperature of the hot air can also be controlled within other temperature ranges, which is not limited in this embodiment.

[0083] In the electronic smoking device 1000 of this embodiment, please refer to Figure 3 The inner peripheral wall of the sleeve 20 forms a first air passage N1 with the second heating element 61 of the second heating assembly 60 , the partition tube 40 and the outer peripheral wall of the shell 31 in sequence.

The first air channel N1 is connected to the outside air and the second air channel N2, and the second air channel N2 is connected to the bottom of the placement cavity M. Optionally, the through grooves 322 are evenly and spacedly arranged along the circumferential direction of the first heating element 32. Such an arrangement facilitates uniform heating of the air.

[0085] Please combine Figure 2 The cover 80 is also provided with ventilation holes 82, which are arranged on the outer peripheral side of the opening 81. The ventilation holes 82 are communicated with the first air passage N1. In this embodiment, the number of the ventilation holes 82 is four, but it is not limited thereto.

[0086] The recessed portion 321 is isolated from the second air passage N2 so that the metallic smell generated by the first heating element 33 cannot enter the second air passage N2 and diffuse to the placement cavity M, thereby improving the taste.

[0087] Please refer to Figure 7 The partition tube 40 includes a tube body 41 and a fixing portion 42, and the fixing portion 42 is connected to the end of the tube body 41. The fixing portion 42 is sleeve-shaped. The shell 31 includes a convex ring 311, which is arranged on the outer periphery of the shell 31 and is located at an end of the shell 31 away from the base 10.

[0088] The fixing portion 42 is sleeved on the convex ring 311, and the convex ring 311 is interference-fixedly connected with the fixing portion 42. Optionally, in some embodiments, there are multiple fixing portions 42, and the multiple fixing portions 42 are evenly arranged around the end of the tube body 41, and the fixing portion 42 is snap-fitted with the convex ring 311.

[0091] The second heating element 61 is cylindrical. The second heating element 61 is arranged on the partition tube 40. Optionally, the second heating element 61 is formed by ceramic sintering. Specifically, the second heating element 61 can be one or a mixture of a silicon dioxide sintered body, an aluminum oxide sintered body, a silicon nitride sintered body, a zirconium oxide sintered body or a silicon carbide material sintered body. The second heating element 61 is made of ceramic material. On the one hand, it has high thermal conductivity, fast heat conduction speed and small specific heat capacity, and less heat loss during heating; on the other hand, it has stable performance at high temperature, does not undergo chemical reactions such as decomposition to produce harmful substances and odors, and has poor oil absorption, and will not combine with tobacco oil to produce odor. Of course, the second heating element 61 can also be made of other materials, and this application is not limited.

[0092] In addition, the second heating element 61 is provided coaxially with the partition pipe 40 .

[0093] The second heating element 62 is disposed on the outer periphery of the second heating element 61, and is used to heat the second heating element 61.

[0094] The second temperature sensing element 63 is disposed on the second heating element 61, and is used to sense the temperature of the second heating element 61. The second temperature sensing element 63 is electrically connected to the control driving module 200. Optionally, the second temperature sensing element 63 is a thermocouple or other device for sensing temperature.

[0095] The barrier layer 64 covers the resistance wire and the second heating element 61. In this embodiment, the barrier layer 64 covers the second heating element 62 to isolate the second heating element 62 and the first airway N1, thereby preventing the metallic smell of the second heating element 62 from entering the first airway N1 and diffusing to the placement cavity M, thereby improving the taste of the smoke.

[0096] Optionally, the material of the barrier layer 64 may be ceramic or other materials that can prevent the odor from entering the first air passage N1 through the resistor wire.

[0097] In this embodiment, the heating module 300 detects the temperature of the second heating element 61 through the second temperature sensing element 63, and compares the real-time temperature with the target set temperature in the control driving module 200 to control the temperature of the second heating element 61, so as to ensure that the temperature of the hot air of the second heating element 61 is controlled between 220 degrees Celsius and 280 degrees Celsius, thereby ensuring a comfortable taste of the smoking medium. Of course, the temperature of the hot air can also be controlled within other temperature ranges, which is not limited in this embodiment.
