Further, the cover body 23 is provided with a liquid inlet hole 22, the liquid storage chamber 12 stores an aerosol generating substrate, the liquid inlet hole 22 is in fluid communication with the atomizing core 30, and the aerosol generating substrate in the liquid storage chamber 12 passes through the liquid inlet hole 22 It flows to the atomizing core 30; the cover body 23 is provided with a ventilation groove 36, which is arranged around the liquid inlet hole 22, and the ventilation groove 36 is connected to the liquid inlet hole 22 and the atomization chamber 25, and the ventilation groove 36 has capillary action The electronic atomization device 100 includes a gasket 38 , the gasket 38 covers the ventilation slot 36 and is located between the atomization core 30 and the cover 23 .

Specifically, the cover body 23 of the top cover 20 is also provided with a liquid inlet hole 22, the liquid inlet hole 22 is conducive to the flow of the aerosol generating substrate stored in the liquid storage chamber 12 to the atomizing core 30, so that the aerosol generating substrate can be It directly flows into the atomization core 30, thereby improving the atomization efficiency of the atomization core 30.

As the aerosol-generating substrate stored in the liquid storage chamber 12 is consumed by the atomizing core 30, the air pressure in the liquid storage chamber 12 gradually decreases, and the pressure difference between the inside and outside of the liquid storage chamber 12 increases continuously, and finally the air pressure in the liquid storage chamber 12 increases. The aerosol-generating substrate cannot continuously flow into the atomizing core 30 , which is not conducive to the continuous use of the electronic atomizing device 100 . Therefore, in the present application, a ventilation groove 36 is provided on the cover body 23. The ventilation groove 36 communicates with the liquid inlet hole 22 and the atomization chamber 25, and can deliver gas to the liquid storage chamber 12 to balance the internal and external pressure of the liquid storage chamber 12, and then It is beneficial for the aerosol-generating substrate to continuously and smoothly flow into the atomizing core 30 . In addition, the air exchange groove 36 is arranged on the cover body 23 and is arranged around the liquid inlet hole 22, wherein the air exchange groove 36 is a capillary groove, thereby preventing the aerosol atomized substrate in the liquid storage chamber 12 from the air exchange groove 36 Leaks to the atomization chamber 25.

Optionally, the gas mist outlet hole 21 is isolated from the peripheral wall of the cover body 23 .

Specifically, the gas mist outlet hole 21 directly communicates with the atomization chamber 25, and the airflow from the atomization chamber 25 to the gas mist outlet hole 21 does not need to pass through the inner wall of the housing 11, which eliminates the aerosol generated by atomization and The risk of condensation caused by the contact of the inner wall of the housing 11 effectively reduces the risk of the aerosol remaining in the atomizing chamber 25 due to condensation, and can further increase the aerosol yield of the electronic atomization device 100 .

Further, the gas mist outlet hole 21 is a straight hole, and it directly communicates with the atomization chamber 25 , so that the aerosol generated in the atomization chamber 25 can directly lead to the air outlet pipe 13 without passing through the inner wall of the housing 11 .

Optionally, the first port 47 of the air hole 41 and the second port 48 of the gas mist exit hole 21 are respectively located on two sides of the atomizing core 30 .

Since the first port 47 of the air hole 41 and the second port 48 of the gas mist outlet hole 21 are respectively arranged on both sides of the atomization core 30, when the gas flows into the atomization chamber 25 from the first port 47, the gas will flow from the atomization core One side of 30 flows to the other side, that is, flows from the side where the gas hole 41 is to the side where the gas mist outlet 21 is, and then crosses the surface of the atomization core 30, and when the gas flows to the side where the gas mist outlet 21 is, it carries The aerosol generated by the heating of the atomizing core 30 immediately enters the channel of the gas mist outlet 21 , and flows from the second port 48 of the gas mist outlet 21 into the air outlet pipe 13 for the user to inhale through the air outlet 14 .

This application allows the gas to cross the surface of the atomization core 30 during the process of the gas flowing into the atomization chamber 25 from the air hole 41 and then flowing out from the gas mist outlet hole 21, so that the gas generated after atomization can be taken away to a greater extent and more efficiently. The aerosol, that is, the airflow can more fully carry the aerosol generated on the surface of the atomizing core 30 to flow to the air outlet pipe 13, so as to avoid the aerosol from staying in the atomizing chamber 25, effectively improving the aerosol yield and improving the fogging effect. efficiency.

In another embodiment of the present application, the channel path of the gas mist exit hole 21 may also be curved. The second port 48 can also be located outside the atomizing chamber 25 .

Specifically, the atomizing surface 39 includes two opposite long sides 45 and two opposite short sides 46 , and the length of the long sides 45 is greater than the length of the short sides 46 .

When the gas flows into the atomization chamber 25 from the first port 47 of the gas hole 41, the gas will flow along the extension direction of the short side 46 and across the atomization surface 39, and finally flow out of the mist from the second port 48 of the gas mist outlet hole 21 Chemical chamber 25. Therefore, at this time, the gas only needs to cross the atomizing surface 39 roughly along the extension direction of the short side 46 , so that the aerosol generated by the atomizing core 30 can be transported more efficiently and quickly, and the atomization efficiency can be improved.

In other embodiments, the first port 47 and the second port 48 can also cross the atomizing surface 39 along the extending direction of the long side 45 .

The atomizing core 30 can also be in the shape of a rectangle, trapezoid, cylinder, etc., and can be a ceramic core, a silicon carbide atomizing core 30 or a cotton core, which is not specifically limited in this application.

For example, the gas mist outlet hole 21 is centrally disposed on the cover body 23 , and the gas mist outlet hole 21 is isolated from the outer peripheral wall of the cover body 23 .

Since the length of the long side 45 is relatively large, the application can appropriately increase the distance between the two electrodes 70 to reduce or avoid eddy currents. Therefore, the airflow entering the atomizing chamber 25 from the air hole 41 can flow through the atomizing surface 39 more efficiently, and can also efficiently take away the aerosol generated between the two electrodes 70 to increase the aerosol yield.

The two electrodes 70 are relatively located on opposite sides of the air hole 41 , that is, the distance between the two electrodes 70 is greater than the maximum dimension of the air hole 41 . In this embodiment, the number of air holes 41 is multiple, and they are distributed at intervals along the extending direction of the long side 45.
