The inner diameter of the communication pipe 70 is small, so that the atomized liquid is difficult to enter the communication pipe 70 from the first cavity 13 under the action of surface tension.

[0069] For example, when the atomization assembly 100 is used in the electronic cigarette, when the user inhales through the air outlet 111, the atomized liquid in the first cavity 13 enters the atomization pipe 20, the pressure in the first cavity 13 becomes smaller, and the air outside the atomization assembly 100 can enter the first cavity 13 through the air inlet channel 521, the first cavity 13, the oil storage cotton 60 and the communication pipe 70 in turn, so that the pressure in the first cavity 13 becomes larger, the speed of the atomized liquid entering the atomization pipe 20 from the first cavity 13 is accelerated, and the volume of the atomized liquid inhaled by the user is increased. When the user does not use the electronic cigarette for a long time, the atomized liquid in the first cavity 13 enters the oil guide 30 from the first oil inlet hole 21, and the oil guide 30 is filled with the atomized liquid and reaches an equilibrium state, and a small amount of atomized liquid in the first cavity 13 leaks into the oil storage cotton 60 under the action of gravity through the communication pipe 70. When the user inhales again through the air outlet 111, the pressure in the first cavity 13 becomes smaller, and the pressure in the first cavity 13 is smaller than the pressure in the oil storage cotton 60, so that the atomized liquid in the oil storage cotton 60 enters the first cavity 13 from the communication pipe 70.

[0070] Optionally, the communication pipe 70 can be made of a breathable material such as polypropylene and fiber cotton. When the pressure in the first cavity 13 becomes smaller, the communication pipe 70 can deliver more air to the first cavity 13. By setting the communication pipe 70 to different densities, the speed of the air delivered by the communication pipe 70 to the first cavity 13 can be changed, and thus the speed of the atomized liquid entering the oil guide 30 can be changed.

[0071] The atomization assembly 100 has the following advantages. The communication pipe 70 is arranged to connect the oil storage cotton 60 and the first cavity 13, air can be introduced into the first cavity 13, the pressure in the first cavity 13 can be relatively stable, and the speed of the atomized liquid entering the atomization pipe 20 from the first cavity 13 can be stable. When the atomization assembly 100 is used in the electronic cigarette, the volume of the atomized liquid inhaled by the user can be stable when the user inhales through the air outlet 111. At the same time, when the user inhales through the air outlet 111, the pressure in the first cavity 13 is smaller than the pressure in the oil storage cotton 60, so that the atomized liquid in the oil storage cotton 60 can be sucked into the first cavity 13 from the communication pipe 70, and the atomized liquid in the oil storage cotton 60 can be prevented from leaking out of the second cavity 53.

[0072] In some embodiments, please refer to Figures 1 to 3The first oil tank 10 comprises a first shell 11 and a support plate 12 connected to the first shell 11, the first shell 11 and the support plate 12 enclose a first cavity 13, and an air inlet 121 is arranged on the support plate 12; and the second oil tank 50 comprises a second shell 51, and the second shell 51 and the support plate 12 enclose a second cavity 53.

[0079] In some embodiments, please refer to Figure 1 and Figure 2The limiting through hole 1221 is provided with a flange 1222 protruding towards the inside of the limiting through hole 1221 on the hole wall of the limiting through hole 1221. The communication pipe 70 is arranged in the limiting through hole 1221, and an end of the communication pipe 70 away from the oil storage cotton 60 abuts against a side of the flange 1222 away from the first oil reservoir 10.

[0080] The limiting through hole 1221 communicates the first cavity 13 and the second cavity 53, that is, the openings at both ends of the limiting through hole 1221 are located in the first cavity 13 and the second cavity 53, respectively.

[0081] The communication pipe 70 is arranged in the limiting hole, that is, the limiting hole can limit the position of the communication pipe 70 in the radial direction. Optionally, the communication pipe 70 is tightly matched with the hole wall of the limiting hole, so as to prevent the atomized liquid in the first cavity 13 from leaking out of the gap between the limiting hole and the communication pipe 70.

[0083] Optionally, the flange 1222 is an annular structure extending along the circumferential direction of the limiting through hole 1221, and the contact area between the flange 1222 and the communication pipe 70 is large, so as to stably limit the communication pipe 70.

[0084] The beneficial effects of the embodiments of the present application are that the limiting through hole 1221 can limit the position of the communication pipe 70 in the radial direction, the flange 1222 can limit the position of the communication pipe 70 in the axial direction by abutting the communication pipe 70 against the oil storage cotton 60, and the limiting through hole 1221 and the flange 1222 can stabilize the communication pipe 70, so as to stably communicate the first cavity 13 and the oil storage cotton 60.

[0085] In some embodiments, please refer to Figure 1 and Figure 2 The second oil reservoir 50 comprises an air inlet pipe 52, and an air inlet channel 521 is formed in the air inlet pipe 52.

[0086] The air inlet pipe 52 is connected to the second shell 51 or the support plate 12. One end of the air inlet pipe 52 is located in the second cavity 53, and the other end of the air inlet pipe 52 is located on the outer surface of the second shell 51 or outside the second shell 51, so as to communicate the second cavity 53 with the outside of the atomization assembly 100. The annular inner wall surface of the air inlet pipe 52 surrounds the air inlet channel 521. Optionally, the air inlet pipe 52 and the second shell 51 are an integral structure, which can improve the production efficiency.

[0087] Optionally, the oil storage cotton 60 is arranged along the length direction of the communication pipe 70 and is spaced apart from the support plate 12. In the length direction of the communication pipe 70, the end of the air inlet pipe 52 located in the second cavity 53 is located between the oil storage cotton 60 and the support plate 12, so as to prevent the atomized liquid in the oil storage cotton 60 from entering the air inlet pipe 52.

[0088] The application has the beneficial effect that the air inlet channel 521 is formed in the air inlet pipe 52. When the air inlet channel 521 is arranged at a position close to the oil storage cotton 60, the pipe wall of the air inlet pipe 52 can separate the air inlet channel 521 from the oil storage cotton 60, so as to prevent the atomized liquid in the oil storage cotton 60 from entering the air inlet channel 521.

[0089] In some embodiments, please refer to Figures 1 to 5 , the atomization assembly 100 comprises a first oil reservoir 10, an atomization pipe 20, an atomization core assembly 40, an oil guide 30, a first sealing structure 80, a second sealing structure 90, a second oil reservoir 50, an oil storage cotton 60, and a communication pipe 70. The first oil reservoir 10 comprises an air inlet 121, an air outlet 111, and a first cavity 13. The atomization pipe 20 is arranged in the first cavity 13, and the two ends of the atomization pipe 20 are connected with the air outlet 111 and the air inlet 121, respectively. The atomization pipe 20 is provided with a first oil inlet hole 21 for guiding the atomized liquid in the first oil reservoir 10 into the atomization pipe 20. The atomization core assembly 40 is arranged in the atomization pipe 20, and has a gap with the atomization pipe 20. The atomization core assembly 40 is used for atomizing the atomized liquid. The atomization core assembly 40 comprises an air inlet end 41 communicated with the air inlet 121 and an air outlet end 42 communicated with the air outlet 111. In the length direction X of the atomization pipe 20, the air outlet end 42 is arranged between the air inlet end 41 and the air outlet 111. The oil guide 30 is arranged between the atomization pipe 20 and the atomization core assembly 40. The oil guide 30 covers the first oil inlet hole 21 and covers at least part of the atomization core assembly 40. The oil guide 30 is used for guiding the atomized liquid in the atomization pipe 20 to the atomization core assembly 40. The first sealing structure 80 is arranged on the side of the oil guide 30 close to the air outlet end 42 along the length direction X of the atomization pipe 20. The first sealing structure 80 is used for sealing the gap between the atomization core assembly 40 and the atomization pipe 20, so as to hinder the atomized liquid in the oil guide 30 from entering the air outlet 111.

[0090] The second sealing structure 90 is arranged on the side of the oil guide 30 close to the air inlet end 41 along the length direction X of the atomization pipe 20. The second sealing structure 90 is used for sealing the gap between the atomization core assembly 40 and the atomization pipe 20, so as to hinder the atomized liquid in the oil guide 30 from entering the air inlet 121.

[0091] The second oil tank 50 has a second cavity 53 and an air inlet channel 521, the second cavity 53 is communicated with the air inlet 121, and the air inlet channel 521 is communicated with the second cavity 53 and the outside respectively; the oil storage cotton 60 is arranged in the second cavity 53, and the oil storage cotton 60 is used for absorbing the atomized liquid in the second cavity 53. The two ends of the communication pipe 70 are arranged in the first cavity 13 and the oil storage cotton 60 respectively, and the communication pipe 70 is used for transmitting the atomized liquid and the air between the first cavity 13 and the oil storage cotton 60.

[0092] For example, when the atomization assembly 100 is used in the electronic cigarette, the atomized liquid in the first cavity 13 enters the oil guide 30 through the first oil inlet hole 21, and the oil guide 30 guides the atomized liquid into the atomization core assembly 40. When the user inhales through the air outlet 111, the air outside the atomization assembly 100 enters the atomization pipe 20 through the air inlet 121, the air in the atomization pipe 20 enters the atomization core assembly 40 through the air inlet end 41, the atomization core assembly 40 atomizes the atomized liquid into smoke, and the smoke and the air in the atomization pipe 20 are sequentially taken out through the air outlet end 42 and the air outlet 111.

[0093] After the atomized liquid in the first cavity 13 enters the atomization pipe 20, the pressure in the first cavity 13 becomes smaller, the air outside the atomization assembly 100 can enter the first cavity 13 through the air inlet channel 521, the first cavity 13, the oil storage cotton 60 and the communication pipe 70 in sequence, the pressure in the first cavity 13 becomes larger, the speed of the atomized liquid entering the atomization pipe 20 from the first cavity 13 increases, and the atomized liquid inhaled by the user increases.

[0094] When the user does not use the electronic cigarette for a long time, the atomized liquid in the first cavity 13 leaks into the oil storage cotton 60 under the action of gravity, and when the user inhales again through the air outlet 111, the pressure in the first cavity 13 becomes smaller, the pressure in the first cavity 13 is smaller than the pressure in the oil storage cotton 60, and the atomized liquid in the oil storage cotton 60 enters the first cavity 13 from the communication pipe 70.
