Thus, the air flow does not need to flow through the inner wall surface of the housing 11, so that a large amount of condensate is prevented from being generated when flowing through the inner wall surface of the housing 11, and atomization efficiency is prevented from being affected.

Referring to fig. 5 to 7, fig. 5 is a schematic diagram illustrating an assembly structure of the top cover 20 and the atomizing core 30 shown in fig. 3; fig. 6 is a schematic bottom view of the top cover 20 of fig. 3; fig. 7 is a schematic cross-sectional view of the atomizing cartridge 10 and the base 40 shown in fig. 2.

Wherein, the first wall portion 29 may be arc-shaped, and a partition plate 32 is connected to the first wall portion 29, the partition plate 32 and the first wall portion 29 cooperate with each other to form at least part of the duct of the aerosol outlet 21, one end of the partition plate 32 abuts against the third wall portion 34, and the other end abuts against a fourth wall portion 35 opposite to the third wall portion 34.

Of course, the present application may not provide the first heat insulating chamber 27, the second heat insulating chamber 28, the third heat insulating chamber or the fourth heat insulating chamber, and the wall portion of the partition wall 24 may be used to separate the atomizing chamber 25 from the inner wall surface of the housing 11, thereby achieving a certain heat insulating effect and increasing the volume of the atomizing chamber 25.

Further, the cover 23 is provided with a liquid inlet hole 22, the liquid storage cavity 12 stores aerosol generating matrix, the liquid inlet hole 22 is in fluid communication with the atomizing core 30, and the aerosol generating matrix in the liquid storage cavity 12 flows to the atomizing core 30 through the liquid inlet hole 22; the cover body 23 is provided with a ventilation groove 36, the ventilation groove 36 is arranged around the liquid inlet 22, the ventilation groove 36 is communicated with the liquid inlet 22 and the atomization cavity 25, and the ventilation groove 36 has capillary action; the electronic atomizing device 100 includes a gasket 38, the gasket 38 covering the ventilation slot 36 and being located between the atomizing core 30 and the cover 23.

Specifically, the cover body 23 of the top cover 20 is further provided with a liquid inlet 22, and the liquid inlet 22 is beneficial to the aerosol-generating substrate stored in the liquid storage cavity 12 to flow to the atomizing core 30, so that the aerosol-generating substrate can directly flow into the atomizing core 30, and the atomizing efficiency of the atomizing core 30 is improved.

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 the outside of the liquid storage chamber 12 is continuously increased, so that the aerosol-generating substrate in the liquid storage chamber 12 cannot continuously flow into the atomizing core 30, which is not beneficial to the continuous use of the electronic atomizing device 100. Therefore, the cover 23 is provided with the ventilation groove 36, the ventilation groove 36 is communicated with the liquid inlet hole 22 and the atomization cavity 25, and can be used for conveying gas to the liquid storage cavity 12 so as to balance the internal and external pressure of the liquid storage cavity 12, thereby being beneficial to continuously and smoothly flowing the aerosol generating substrate into the atomization core 30. In addition, the ventilation groove 36 is disposed on the cover 23 and surrounds the liquid inlet 22, wherein the ventilation groove 36 is a capillary groove, so as to prevent the aerosol atomized substrate in the liquid storage chamber 12 from leaking from the ventilation groove 36 to the atomizing chamber 25.

The electronic atomizing device 100 of the present application further comprises a sealing gasket 38 disposed between the atomizing core 30 and the cover 23, wherein the sealing gasket 38 is used for sealing the ventilation slot 36, such that the ventilation slot 36 forms a relatively airtight air flow channel, and the gap between the cover 23 and the atomizing core 30 is sealed to avoid liquid leakage.

Alternatively, the aerosol outlet 21 is provided separately from the outer peripheral wall of the lid 23.

Specifically, the aerosol outlet 21 is directly connected to the atomizing chamber 25, and the airflow from the atomizing chamber 25 to the aerosol outlet 21 does not need to pass through the inner wall surface of the housing 11, that is, the risk that the aerosol generated by atomization is condensed due to contact with the inner wall surface of the housing 11 is eliminated, the risk that the aerosol stays in the atomizing chamber 25 due to condensation is effectively reduced, and the aerosol output of the electronic atomizing device 100 can be further improved.

Further, the aerosol outlet 21 is a through hole and is directly connected to the atomizing chamber 25, so that the aerosol generated in the atomizing chamber 25 can be directly led to the air outlet pipe 13 without passing through the inner wall surface of the housing 11.

Alternatively, the first port 47 of the air hole 41 and the second port 48 of the aerosol outlet 21 are located on both sides of the atomizing core 30, respectively.

Since the first port 47 of the air hole 41 and the second port 48 of the aerosol outlet 21 are disposed at two sides of the atomizing core 30, when the air flows into the atomizing chamber 25 from the first port 47, the air flows from one side of the atomizing core 30 to the other side, i.e. from the side of the air hole 41 to the side of the aerosol outlet 21, and further spans the surface of the atomizing core 30, and when the air flows to the side of the aerosol outlet 21, the air carries the aerosol heated by the atomizing core 30, and then enters the passage of the aerosol outlet 21, and flows into the air outlet pipe 13 from the second port 48 of the aerosol outlet 21, so as to be sucked by the user from the air outlet 14.

The application ensures that the gas can cross the surface of the atomizing core 30 in the process of flowing into the atomizing cavity 25 from the air hole 41 and flowing out from the aerosol outlet hole 21, thereby carrying away the aerosol generated after atomization to a greater extent and with higher efficiency, namely the gas flow can more fully carry the aerosol generated on the surface of the atomizing core 30 to the gas outlet pipe 13, so as to avoid the aerosol from being detained in the atomizing cavity 25, effectively improve the output of the aerosol and improve the atomizing efficiency.

In another embodiment of the present application, the path of the aerosol outlet 21 may also be curved. The second port 48 may also be located outside the nebulization chamber 25.

Alternatively, the atomizing face 39 of the atomizing core 30 is directed toward the atomizing chamber 25, the atomizing face 39 is a rectangular face, the atomizing face 39 has a long side 45 and a short side 46, and the first port 47 of the air hole 41 and the second port 48 of the air-mist outlet opening 21 are arranged such that the air flow crosses the atomizing face 39 in the extending direction of the short side 46.

Specifically, the atomizing face 39 includes two opposing long sides 45 and two opposing short sides 46, with the long sides 45 having a length greater than the length of the short sides 46.

When gas flows into the nebulization chamber 25 from the first port 47 of the air hole 41, the gas will flow in the direction of extension of the short side 46 and across the nebulization surface 39, eventually exiting the nebulization chamber 25 from the second port 48 of the aerosol outlet aperture 21. Therefore, the gas only needs to traverse the atomizing surface 39 substantially along the extending direction of the short side 46, and the aerosol generated by the atomizing core 30 can be transported more efficiently and quickly, thereby improving the atomizing efficiency.

In other embodiments, the first port 47 and the second port 48 may also span across the atomizing face 39 along the extension of the long side 45.

Notably, the atomizing face 39 may also be a circular face or an elliptical face, or the like. The atomizing core 30 may be rectangular, trapezoidal, cylindrical, etc., and may be a ceramic core, a silicon carbide atomizing core 30, a cotton core, etc., which is not particularly limited in the present application.
