As shown in fig. 1 and 3, the electronic cigarette of the utility model comprises a shell 8, an oil tank 4, a battery compartment 5 and an air flue 2, wherein the oil tank 4 and the battery compartment 5 are positioned inside the shell 8, an air tap 1 communicated with the oil tank 4 and used for sucking is arranged on the shell 8, an oil tank air inlet 20 communicated with the battery compartment 5 is arranged on the oil tank 4, and the oil tank air inlet 20 is used for exchanging substances between the battery compartment 5 and the air flue 2. The air flue 2 is arranged in the oil tank 4 and is communicated with the air tap 1 through the oil tank air inlet 20, the air flue 2 is provided with a heating body 3 for heating the oil tank 4 to atomize tobacco tar, wherein the inner wall of the air flue 2 is provided with an opening for the heating body 3 to transversely penetrate, the heating body 3 is of a rod-shaped structure and transversely penetrates in the middle of the air flue 2, and the diameter of the heating body 3 is smaller than that of the air flue 2, so that the air flue 2 cannot be blocked. The structure of the heating body 3 generally comprises an oil guiding body and a heating piece, wherein the oil guiding body is used for guiding tobacco tar in the oil tank 4 to the heating piece, and the heating piece heats the tobacco tar on the oil guiding body to generate smoke. The structural form is generally as follows: 1. a heating element structure formed by winding heating wires or heating meshes around the oil guide body; 2. the surface of the block-shaped oil body is printed with a heating coating, a heating circuit or a heating body structure formed by combining the block-shaped oil body and a metal heating net sheet. The oil guide body can be made of porous materials such as cotton, fiber, non-woven fabric, ceramic and the like or materials capable of adsorbing and transmitting tobacco tar. The heating body 3 is used for generating heat, so that tobacco tar in the oil tank 4 is atomized into aerosol mist, and the generated aerosol mist is mixed with air through the air channel 2 by air flow caused by upward suction and enters the oral cavity. The battery compartment 5 is internally provided with a microphone 6 for controlling the heating body 3 to work, the battery compartment 5 is internally provided with a microphone bracket 7 for fixing the microphone 6, the microphone 6 is positioned inside the microphone bracket 7, the microphone bracket 7 is provided with the microporous breathable film 13 for isolating the microphone 6 from the inner cavity of the battery compartment 5 in order to protect the microphone 6, and the microporous breathable film 13 is used for blocking aerosol mist, tobacco tar, condensate and the like in the inner space of the battery compartment 5 from entering the microphone upper space 11. The space inside the microphone holder 7 is divided into a microphone upper space 11 and a microphone lower space 12 by the microphone 6. The upper space 11 of the microphone is communicated with the inner space of the battery compartment 5, and the lower space 12 of the microphone is communicated with the atmosphere 18. The upper part of the microphone bracket 7 is provided with a microphone upper air inlet 14, and the microphone upper air inlet 14 is used for communicating the microphone upper space 11 with the inner space of the battery compartment 5. A microphone lower air inlet 10 is provided at the bottom of the housing 8, which microphone lower air inlet 10 is adapted to communicate the microphone lower space 12 with the atmosphere 18. The bottom of the housing 8 is also provided with a bottom air inlet 9, which bottom air inlet 9 is used to communicate the interior space of the battery compartment 5 with the atmosphere 18.

The microphone 6 is a common electronic cigarette control sensor, and controls the starting and stopping of the electronic cigarette by detecting and calculating the air pressure difference between the microphone upper space 11 and the microphone lower space 12. In the implementation of the electronic cigarette, the microphone 6 is arranged in the battery compartment 5, the air pressure of the upper space 11 of the microphone is related to the air pressure of the battery compartment 5, and the lower space 12 of the microphone is communicated with the atmosphere 18, so that the air pressure of the lower space 12 of the microphone is ensured to be the fixed atmosphere pressure.

When the user is using the e-cigarette, the direction of air flow of the atmosphere 18 when the e-cigarette is in operation is shown by the arrow in fig. 1. The upward suction of the user causes air of the atmosphere 18 to enter the battery compartment 5 from the bottom air inlet 9, and air in the inner space of the battery compartment 5 is sucked into the user's mouth through the oil compartment air inlet 20, the air duct 2 and the air tap 1, and at this time, a slight negative pressure is generated in the battery compartment 5. Air in the upper space 11 of the microphone is sucked into the battery compartment 5 through the microporous breathable film 13, so that air pressure in the upper space 11 of the microphone and air pressure in the lower space 12 of the microphone form an air pressure difference, and when the air pressure difference exceeds a preset air pressure difference, the microphone 6 starts to work. The electronic cigarette generates heat through the heating body 3, so that tobacco tar in the oil tank 4 is atomized into aerosol mist, and the generated aerosol mist is mixed with air in the inner space of the battery tank 5 through the air channel 2 and the air tap 1 by air flow caused by upward suction and enters an oral cavity. When the user stops pumping upwards, the micro negative pressure in the battery compartment 5 disappears, and the air in the inner space of the battery compartment 5 is sucked into the upper space 11 of the microphone through the micro-porous ventilated membrane 13. At this time, the air pressure difference between the air pressure of the upper space 11 and the air pressure of the lower space 12 becomes smaller gradually, and when the air pressure difference is lower than the preset air pressure difference, the microphone 6 stops working, and the heating body 3 stops generating heat.

Referring to fig. 1, 2 and 3, the microporous breathable film 13 according to the embodiment of the present utility model is formed by laminating and hot-pressing an expanded polytetrafluoroethylene film 15 and a fabric 16, and the composition process is a mature hot-pressing process, and has low cost. The expanded polytetrafluoroethylene membrane 15 comprises at least two expanded polytetrafluoroethylene sub-membranes 19, and the expanded polytetrafluoroethylene sub-membranes 19 are laminated together by stacking and hot pressing. The expanded polytetrafluoroethylene membrane 15 is provided with holes for gas permeation at both sides of the membrane; holes for gas penetration on two sides of the sub-membrane are also formed on the expanded polytetrafluoroethylene sub-membrane 19; the pores of the expanded polytetrafluoroethylene film 15 are formed by compounding Kong Diefang on at least two layers of expanded polytetrafluoroethylene sub-films 19 together through hot pressing; the micropores of the microporous breathable film 13 are holes formed by stacking holes on the expanded polytetrafluoroethylene film 15 and holes on the fabric 16, and the pore diameter of the micropores can be any size between 0.05 and 0.5 micrometers. Because the aperture size of the micropores on the microporous breathable film 13 directly influences the sensitivity of the electronic cigarette microphone 6 for controlling the operation of the heating body 3 of the electronic cigarette, namely when the aperture size of the micropores on the microporous breathable film 13 is larger, the ventilation amount of the microporous breathable film 13 is larger, and a user can trigger the microphone 6 to start with smaller suction force; when the pore size of the micropores on the microporous breathable film 13 is smaller, the ventilation amount of the microporous breathable film 13 is smaller, and a user needs larger suction force to trigger the microphone 6 to start. Accordingly, the pore size of the micropores on the microporous breathable film 13 can be set according to the taste requirement of the user's suction force, wherein the preferred value is 0.2 μm. Since the aerosol mist particle size is generally between 0.5 and 3 microns, the pore size of the micropores of the microporous breathable film 13 is smaller than the aerosol mist particle size, and penetration of the aerosol mist particles can be effectively blocked. The aperture of the micropore on the micropore ventilated membrane 13 is smaller than the size of aerosol fog particles, so as to protect the microphone 6 in the microphone bracket 7, avoid the microphone 6 from being corroded by aerosol fog or condensate or leaked tobacco tar, damage the microphone 6, or cause the occurrence of bad phenomena such as self-starting or non-starting of the microphone, and lead the microphone 6 to be incapable of normally controlling the starting and stopping of the electronic cigarette.

The thickness of the fabric 16 is generally between 20 and 50 microns (30 microns is preferred), and the weaving pattern may be plain, twill, satin, etc., with a mesh size of between 10 and 100 mesh (60 mesh is preferred). The pores of the fabric 16 are generally much larger than the pore size of the pores of the expanded polytetrafluoroethylene membrane 15 without affecting the penetration properties of the microporous breathable membrane 13.

In practical application, the number of the expanded polytetrafluoroethylene sub-films 19 in the expanded polytetrafluoroethylene film 15 is 5-10, and the optimal number of the layers is 7; the pore size of the pores in the expanded polytetrafluoroethylene sub-membrane 19 may generally be any size between 0.1 and 1 micron, with a preferred value of 0.6 micron; the thickness of the expanded polytetrafluoroethylene sub-membrane 19 was 0.01 μm.

The assembly mode between the microporous breathable film 13 and the microphone upper air inlet 14 is shown in fig. 3, the microporous breathable film 13 is cut into a shape corresponding to the microphone upper air inlet 14, a groove 17 matched with the shape of the periphery of the microporous breathable film 13 is formed in the periphery of the microphone upper air inlet 14, and the microporous breathable film 13 can be assembled in the groove 17 in a physical press fit mode and forms a microphone upper space 11 together with the microphone 6 and the microphone bracket 7. The micro-pore ventilated membrane 13 isolates the microphone 6 positioned in the microphone bracket 7 from the interior of the electronic cigarette.

The assembly mode between the microporous ventilated membrane 13 and the microphone upper air inlet 14 can be as shown in fig. 4, the microporous ventilated membrane 13 is cut into a shape capable of sealing the microphone upper air inlet 14, and the microporous ventilated membrane 13 is adhered to the inner side or the outer side of the microphone upper air inlet 14 through glue to be fixed, and forms a microphone upper space 11 together with the microphone 6 and the microphone bracket 7. The micro-pore ventilated membrane 13 isolates the microphone 6 positioned in the microphone bracket 7 from the interior of the electronic cigarette.

To sum up, in the electronic cigarette that proposes in this embodiment, through the technical effect that increases the micropore ventilated membrane 13 that sets up on miaow head support 7 and realize ventilative but airtight sol fog, tobacco tar, condensate etc. can effectively separate aerosol fog, tobacco tar, condensate, weeping etc. that electronic cigarette working process produced, avoid corroding the miaow head of electronic cigarette, and then effectively prevent the electronic cigarette because of the miaow head damage safety risk that brings from the start and brought good user experience for the user.
