Referring to fig. 12 to 16, an inner wall of the housing 1 abuts against an outer periphery of the atomizing core sealing member 4, a ventilation channel 401 is formed between the housing 1 and the atomizing core sealing member 4, one end of the ventilation channel 401 is communicated with the atomizing chamber 20, and the other end of the ventilation channel 401 is communicated with the reservoir 10.

Specifically, the ventilation channel 401 may be a through groove that penetrates through the atomizing core sealing member 4 and the housing 1, such that one end of the through groove is directly communicated with the atomizing chamber 20, and the other end of the through groove is communicated with the liquid storage bin 10. Or, the ventilation channel 401 may also be a gap provided between the atomizing core sealing element 4 and the housing 1 in a protruding manner, a certain gap is left between the periphery of the atomizing core sealing element 4 and the inner wall of the housing 1 due to the existence of the protrusion, and the gap provided on the protrusion can be communicated with the atomizing cavity 20 and the liquid storage bin 10 through the gap, so that the ventilation of the liquid storage bin 10 by the atomizing cavity 20 is still ensured although the gap provided on the protrusion is indirectly communicated with the atomizing cavity 20 and the liquid storage bin 10.

In the use of the electronic cigarette atomization component, the tobacco tar in the liquid storage bin 10 can flow to the atomizing core 3 and then is atomized continuously, so that the tobacco tar in the liquid storage bin 10 is reduced continuously, the air pressure in the liquid storage bin 10 can be reduced continuously, and the atomization chamber 20 is communicated with the air inlet channel 22, so that the air pressure in the atomization chamber 20 is the same as or close to the external atmospheric pressure.

Specifically, stock solution storehouse 10 is used for saving the tobacco tar, the tobacco tar in the stock solution storehouse 10 flows extremely behind the atomizing core subassembly, the atomizing core subassembly can atomize the tobacco tar under the circumstances of heating, with form atomizing aerosol in the atomizing chamber 20, atomizing chamber 20 with outlet channel 11 intercommunication, and then make atomizing aerosol pass through outlet channel 11 is inhaled by the user. Under the condition that the tobacco tar in the stock solution storehouse 10 constantly reduces, atmospheric pressure in the stock solution storehouse 10 can constantly reduce, makes atmospheric pressure in the stock solution storehouse 10 for the atomizing chamber can form the negative pressure, gives the tobacco tar in the stock solution storehouse 10 flows smoothly extremely atomizing core subassembly causes the obstacle. And this application through casing 1 with set up air exchange channel 401 between the atomizing core sealing member 4, atomizing core subassembly with casing 1's inner wall encloses to close and forms the intercommunication stock solution storehouse 10 with behind the air exchange channel 401 of atomizing chamber 20, can the atmospheric pressure in the stock solution storehouse 10 for when the atomizing chamber can form the negative pressure, air intake channel 22's the air intake can pass through air exchange channel 401 flows to stock solution storehouse 10, adjusts the air current balance of stock solution storehouse 10 and atomizing chamber 20 through air exchange channel 401. The negative pressure in the liquid storage bin 10 can improve the response speed of the internal and external pressure difference of the liquid storage bin 10 after air is supplemented in time through the ventilation channel 401, so that a user has better suction experience.

More importantly, under the condition of heating and atomizing the atomizing core 3, the temperature of the atomizing core inside the atomizing core 3 is higher, which can reach 200 ℃ and 300 ℃, and higher heat can be emitted. The passageway 401 of taking a breath set up in casing 1 with when atomizing core sealing member 4 between, because the circumference of atomizing core sealing member 4 is kept away from atomizing core 3 makes through atomizing core subassembly with casing 1 encloses the passageway 401 of taking a breath that closes formation and also can keep away from atomizing core 3 has avoided the influence of high temperature to the passageway 401 rate of taking a breath, has guaranteed the stability of taking a breath. And this application the passageway 401 of taking a breath is keeping away from behind the atomizing core 3, can prevent stock solution storehouse 10 to atomizing chamber 20 weeping through the tobacco tar in the stock solution storehouse 10 and the surface tension between the passageway 401 of taking a breath, can avoid high temperature to the influence of the tobacco tar in the stock solution storehouse 10 and the surface tension between the passageway 401 of taking a breath equally, avoid stock solution storehouse 10 to the risk of atomizing chamber 20 weeping.

The embodiment of the application provides electron smog subassembly includes casing 1, lower base 2 and atomizing core subassembly, lower base 2 with 1 cooperation of casing is connected. The atomizing core assembly is arranged in the shell 1, and the atomizing core sealing element 4 is sleeved on the atomizing core 3. The inner wall of the housing 1 abuts against the outer periphery of the atomizing core seal 4, so that a ventilation channel 401 is formed between the housing 1 and the atomizing core seal 4. When the air pressure in the liquid storage bin 10 is lower than the air pressure in the atomizing cavity 20, the air flow in the atomizing cavity 20 can be guided to the liquid storage bin 10 through the air exchange channel 401, and the air exchange channel 401 can adjust the air flow balance between the liquid storage bin 10 and the atomizing cavity 20 on one hand; on the other hand keeps away from the high temperature atomizing core 3 has avoided the high temperature to stock solution storehouse 10 to the influence of atomizing chamber 20 weeping, has guaranteed the atomization effect of electron smog spinning disk atomiser spare for the user has better suction experience.

Optionally, referring to fig. 14 and 15, the periphery of the atomizing core sealing member 4 is provided with a through slot 411 extending from the atomizing chamber 20 to the reservoir 10, and the through slot 411 and the housing 1 enclose to form the ventilation channel 401.

Specifically, the through groove 411 is extended from the atomizing chamber 20 to the liquid storage bin 10, so that the through groove 411 can be directly communicated with the liquid storage bin 10 and the atomizing chamber 20, and the adjustment of the air flow balance between the liquid storage bin 10 and the atomizing chamber 20 can be realized through the through groove 411. Moreover, the through groove 411 is extended from the atomizing cavity 20 to the liquid storage bin 10, so that the atomizing cavity 20 can provide a quick and convenient channel for ventilation of the liquid storage bin 10, and the extending structure of the through groove 411 is simplified, and meanwhile, the air flow balance between the liquid storage bin 10 and the atomizing cavity 20 is ensured.

Optionally, the width of the through slot 411 in the axial direction of the atomizing core seal 4 ranges from 0.2 to 3.0 mm; the depth of the through slot 411 in the axial direction of the atomizing core seal 4 ranges from 0.15 to 0.40 mm.

Specifically, the axial direction of the atomizing core seal 4 is the direction along the atomizing chamber 20 toward the reservoir 10, i.e., the vertical direction in fig. 2 and 3. The through groove 411 forms a vertical groove along the axial direction of the atomizing core sealing element 4, and can communicate the liquid storage bin 10 and the atomizing cavity 20 through the shortest path, so that the air flow balance of the liquid storage bin 10 and the atomizing cavity 20 is ensured.

And when the air pressure in the liquid storage bin 10 can ensure that the tobacco tar in the liquid storage bin 10 smoothly flows, the air flow can be supplemented to the liquid storage bin 10 without the through groove 411. The ventilation channel 401 formed by the through slots 411 is still in an open state. In order to prevent the tobacco tar in the liquid storage bin 10 from leaking to the atomizing chamber 20 through the through slot 411, the width and depth of the through slot 411 in the extending direction thereof need to be controlled so as to seal the through slot 411 by the surface tension of the tobacco tar in the liquid storage bin 10.

Specifically, when the width of the through slot 411 in the extending direction is 0.2-3.0mm, the ventilation volume of the ventilation channel 401 can be ensured, and the airflow balance between the liquid storage bin 10 and the atomizing chamber 20 can be effectively adjusted. When the depth of the through groove 411 in the extending direction is 0.15-0.40mm, the tobacco tar generally comprises propylene glycol, glycerol, perfume, nicotine and polyethylene glycol, and is mainly made of propylene glycol and glycerol. The viscosity of propylene glycol and glycerol is high, and an effective air blocking layer can be formed within the depth dimension range of 0.15-0.40mm, so that the surface tension between the tobacco tar in the liquid storage bin 10 and the surface of the ventilation channel 401 can prevent the liquid storage bin 10 from leaking to the atomizing cavity 20, and the effective utilization of the tobacco tar in the liquid storage bin 10 is ensured.

Optionally, the cross section of the through slot 411 in the extending direction thereof is "U" shaped, "V" shaped, "semicircle" shaped, "small semicircle" shaped, "ladder" shaped, square shaped or "C" shaped.

Specifically, the through slot 411 may be an open groove at the periphery of the atomizing core seal, the opening of the through slot 411 may face the housing 1, and the housing 1 and the through slot 411 may form part of the ventilation channel 401 after being enclosed. The cross-sectional size of the through-groove 411 in the extending direction thereof can be kept consistent, so that the through-groove 411 forms the ventilation channel 401 with consistent channel cross-sectional size in different stages; it is also possible that the cross-sectional size of the through slot 411 in the extending direction thereof is gradually decreased or gradually increased to form the ventilation channel 401 with a varying channel cross-sectional size. For example, when the cross-sectional size of the through slot 411 in the extending direction thereof gradually decreases, that is, the opening of the ventilation channel 401 on the side close to the atomizing chamber 20 is relatively large, the intake air of the intake channel 22 can flow to the reservoir 10 through the ventilation channel 401, so as to ensure the air flow balance between the reservoir 10 and the atomizing chamber 20.

In addition, when the cross section of the through groove 411 in the extending direction thereof is square, the space of the through groove 411 in the width direction thereof may be entirely used for ventilation (including the positions of the four corners), so that the width range of the through groove 411 in the extending direction thereof may be small, such as 0.2-1.5 mm; when the cross section of the through groove 411 in the extending direction is U-shaped, V-shaped, semi-circular or small semi-circular, the ventilation space of the through groove 411 in the width direction is smaller than that of the square, so that the width range of the through groove 411 in the extending direction can be larger, such as 1.2-3.0 mm.

Alternatively, referring to fig. 12 to 16, the atomizing core seal 4 includes a seal body 41 and a rib 42 provided along a circumferential direction of the seal body 41, and the atomizing core seal 4 abuts against an inner side wall of the housing 1 through the rib 42.

Specifically, because the atomizing core sealing element 4 is sleeved on the atomizing core 3, and the inner wall of the housing 1 abuts against the periphery of the atomizing core sealing element 4, so that the atomizing core sealing element 4 separates the liquid storage bin 10 from the atomizing cavity 20, in order to avoid the smoke in the liquid storage bin 10 from leaking to the atomizing cavity 20, the sealing element body 41 may be circumferentially provided with a convex rib 42 to improve the sealing performance of the atomizing core sealing element 4. The ribs 42 may be complete annular ribs, and the number of the ribs 42 may be one or more, so that the ribs 42 are disposed behind the circumferential direction of the seal body 41 to ensure the sealing effect of the atomizing core seal 4.

In addition, the rib 42 may be provided separately from the seal body 41, for example, the rib 42 is wound around the circumference of the seal body 41, so as to adjust the material types of the rib 42 and the seal body 41 respectively; the rib 42 may also be integrally provided with the sealing member body 41, for example, the rib 42 and the sealing member body 41 are integrally formed during molding, for example, an integral sealing member of the rib 42 and the sealing member body 41 is obtained after integral injection molding, so as to improve the molding efficiency of the atomizing core sealing member 4.

In another specific embodiment, the sealing member body 41 may be made of a soft material, so that the inner wall of the housing 1 and the outer periphery of the atomizing core sealing member 4 can still maintain good sealing performance after abutting against each other, and the use of a rib is avoided. The through groove 411 may penetrate through the sealing body 41 in the circumferential direction, so that the ventilation channel 401 may be formed after the inner wall of the housing 1 abuts against the outer periphery of the sealing body 41.

In another specific embodiment, a notch 421 is formed on the rib 42, and the notch 421 and the casing 1 enclose to form at least part of the ventilation channel 401.

Specifically, the atomizing core sealing element 4 includes mutually supporting the sealing element body 41 with during the protruding muscle 42, the passageway 401 of taking a breath can only be for setting up in opening 421 on the protruding muscle 42, this moment the circumference of sealing element body 41 is smooth side, opening 421 with the casing 1 encloses to close and forms at least part the passageway 401 of taking a breath, opening 421 can communicate stock solution storehouse 10 with atomizing chamber 20, and through opening 421 can realize the regulation of air current balance between stock solution storehouse 10 and the atomizing chamber 20.

In another specific embodiment, referring to fig. 15, after the through groove 411 is formed in the circumferential direction of the sealing member body 41, a notch 421 opposite to the through groove 411 may be formed in the rib 42, so that the through groove 411 and the notch 421 jointly form the ventilation channel 401, so as to ensure the ventilation efficiency of the ventilation channel 401 on the atomizing core sealing member 4.

Optionally, the width of the gap 421 along the axial direction of the atomizing core sealing element 4 is in the range of 0.2-3.0 mm; the depth range of the gap 421 along the axial direction of the atomizing core sealing element 4 is 0.15-0.40 mm.

Specifically, the axial direction of the atomizing core seal 4 is the direction along the atomizing chamber 20 toward the reservoir 10, i.e., the vertical direction in fig. 2 and 3. The opening 421 is along the axial of the atomizing core sealing element 4 forms a vertical opening, which can communicate the liquid storage bin 10 and the atomizing cavity 20 by the shortest path, so as to ensure the balance of the air flow of the liquid storage bin 10 and the atomizing cavity 20. And when the gas pressure in the liquid storage bin 10 can ensure that the tobacco tar in the liquid storage bin 10 smoothly flows, the air flow can be supplemented to the liquid storage bin 10 without the opening 421. The ventilation channel 401 formed by the gap 421 is still in an open state. In order to prevent the tobacco tar in the reservoir 10 from leaking to the atomizing chamber 20 through the gap 421, the width of the gap 421 in the extending direction thereof needs to be controlled within the range of 0.2-3.0mm, and the depth thereof needs to be controlled within the range of 0.15-0.40mm, so as to seal the gap 421 by the surface tension of the tobacco tar in the reservoir 10.

Optionally, the number of the ventilation channels 401 is multiple, and the multiple ventilation channels 401 are distributed along the circumferential direction of the atomizing core seal 4.

In particular, the number of the ventilation channels 401 is directly related to the ventilation flow and the balance between the reservoir 10 and the nebulizing chamber 20. For example, when the number of the ventilation channels 401 is one, the ventilation flow rate can only be adjusted by the size of the ventilation channels 401, but because the ventilation channels 401 are arranged in the circumferential direction of the atomizing core sealing member 4, the arrangement of one ventilation channel 401 may prevent the air flow in the atomizing chamber 20 far from the ventilation channel 401 from smoothly flowing to the reservoir 10 through the ventilation channel 401, which is not favorable for the balance of ventilation between the reservoir 10 and the atomizing chamber 20. The number of the ventilation channels 401 is multiple, when the ventilation channels 401 are distributed along the circumferential direction of the atomizing core sealing element 4, the ventilation flow rate of the ventilation channels 401 can be flexibly adjusted according to the number and the size, and the ventilation smoothness of the airflow at each position in the atomizing cavity 20 can be balanced by the ventilation channels 401 according to the setting position of each ventilation channel 401, so that the ventilation efficiency of the ventilation channels 401 is ensured.

Alternatively, referring to fig. 12 and 13, the number of the ventilation channels 401 is two, and the two ventilation channels 401 are symmetrically arranged about the central axis of the atomizing cartridge seal 4.

In particular, the structure of the atomizing core seal 4 can be arranged as a symmetrical structure to achieve structural matching with the atomizing core 3 and the housing 1. For example, the atomizing wick seal 4 can be symmetrical along the dashed line in fig. 13, i.e. the center axis of the atomizing wick seal 4 in fig. 13. The number of ventilation channels 401 may be determined based on the ventilation requirements of the electronic cigarette atomization assembly and the number of liquid storage chambers 10. For example, when the ventilation requirement of the electronic cigarette atomization assembly is high or the number of the liquid storage bins 10 is large, the number of the ventilation channels 401 may be set to be large, and at least one ventilation channel 401 is correspondingly set in one liquid storage bin 10. The quantity of the passageway 401 of taking a breath is two and two the passageway 401 of taking a breath is about when the central axis symmetry of atomizing core sealing member 4 sets up, can balance on the one hand atomizing chamber 20 is to the taking a breath of stock solution storehouse 10, and on the other hand can guarantee the structural symmetry of electron smog atomization component, reaches the effect of balanced taking a breath.

In a specific embodiment, referring to fig. 13, the atomizing core sealing member 4 is oblong in the axial cross section of the electronic aerosol atomization assembly, the axial direction of the electronic aerosol atomization assembly is the direction from the atomizing chamber 20 to the liquid storage bin 10, and the two air exchange channels 401 are arranged along the length direction of the atomizing core sealing member 4, so that the airflow in the atomizing chamber 20 can be efficiently supplemented into the liquid storage bin 10, and the liquid discharge efficiency of the tobacco tar in the liquid storage bin 10 is ensured.

Optionally, referring to fig. 1 to 9, the atomizing core 3 has a liquid absorbing surface facing the housing 1 and an atomizing surface facing the lower base 2, the atomizing core 3 has a notch 31 formed in a direction from the liquid absorbing surface to the atomizing surface, the notch 31 and an inner wall of the housing 1 enclose to form an air flow channel, and the air flow channel is communicated with the air outlet channel 11, so that the atomizing air flow in the atomizing cavity 20 can be conveyed to the air outlet channel 11 through the air flow channel, and finally is inhaled by a user.

In addition, referring to fig. 4 to 7, an air outlet 12 is provided on the housing 1, and the air outlet channel 11 is communicated with the outside through the air outlet 12. The air outlet channel 11 comprises a first cavity 111 and a second cavity 112 extending along the axial direction of the electronic cigarette atomization component, the first cavity 111 is close to the atomization core component, the second cavity 112 is close to the air outlet 12, the cross section of the first cavity 111 is larger than that of the second cavity 112, and as the flow area of the airflow channel is larger, the first cavity 111 can form the buffer from the airflow channel to the second cavity 112, so that the rapid change of the channel cross section in the flow process of the atomization airflow is avoided, and the flow stability of the atomization airflow is ensured.

Referring to fig. 8 to 11, the atomizing core 3 includes a porous body 32 and a heating element 33 disposed on the porous body 32, a liquid absorbing end and an atomizing end are disposed on the porous body 32, the notch 31 is disposed on the porous body 32 and penetrates through the liquid absorbing end and the atomizing end, and the heating element 33 is disposed on the atomizing end. A seal channel 43 is formed in the atomizing core seal 4, the seal channel 43 being opposite the gap 31.

In addition, referring to fig. 2 and fig. 3, the electronic cigarette atomization assembly further includes an electrical connector 5, one end of the electrical connector 5 extends into the porous body 32 and is electrically connected with the heating body 33, a conductive nail 21 penetrates through the lower base 2, and one end of the conductive nail 21 extending into the lower base 2 is abutted against the other end of the electrical connector 5.

Referring to fig. 1 to 3, a lower base sealing member 23 is disposed on the lower base 2 in the circumferential direction, and the lower base sealing member 23 abuts against the inner wall of the casing 1 and forms a seal between the lower base 2 and the inner wall of the casing 1. The lower base 2 is further provided with an oil absorption body 6, the oil absorption body 6 is arranged around the periphery of the air inlet channel 22, and therefore the problem that cooled liquid is absorbed by a user along with smoke or leaks from the air inlet channel 22 can be effectively avoided.

The embodiment of the application also provides an electronic cigarette, which comprises the electronic cigarette atomization component and a power supply.

The power supply can supply power to the heating body 33 through the conductive nail 21 and the electric connecting piece 5, so that the conversion of electric energy and heat energy in the heating body 33 is realized.

Specifically, when the user uses the electronic cigarette, the user draws through the air outlet 12. External air enters the atomizing chamber 20 through the air intake passage 22. The sensor in the electron cigarette senses the action of user's suction, and the electricity between power and the heat-generating body 33 switches on and supplies power to heat the liquid in the atomizing stock solution storehouse 10 and form smog, and air admission atomizing chamber 20 drives smog to be inhaled by the user through air outlet channel 11 and gas outlet 12. The air entering the atomizing chamber 20 causes the smoke to condense and form condensate which is absorbed by the oil absorption body 6, so as to avoid the liquid from being taken away by the smoke and sucked by a user or from being accumulated too much to cause leakage.
