In the present application, the angle a formed between the inner surface 410 of the air inlet 41 and the first surface 430 is less than 90°, and the air inlet 41 has a capillary adsorption effect on the incoming liquid. In other words, the air inlet 41 is a capillary hole. The outside air passes through the air intake hole 41 to enter the space on one side of the first surface 430 to the space on one side of the second surface 432 . The atomizing chamber 22 on one side of the two surfaces 432 .

Further, the air inlet hole 41 is a capillary hole, and the smallest cross-sectional diameter of the air inlet hole 41 along the axis perpendicular to the air inlet hole 41 is greater than or equal to 0.2 mm and less than or equal to 4 mm. The smaller the pore size of the air inlet hole 41, the greater the capillary adsorption force on the leakage liquid, and the better the anti-leakage effect. After data analysis and test verification, when the minimum diameter of the air inlet hole 41 is less than or equal to 4mm, the air inlet hole 41 The capillary adsorption force to the leakage liquid is larger, and the leakage prevention effect is better. However, the air intake hole 41 is also used for ventilation, so its suction resistance is not easy to be too large. Excessive suction resistance will cause difficulty in air intake, so that the atomization chamber 22 cannot be sufficiently nourished, and the atomization of the liquid matrix will be insufficient. Sufficiently, under this condition, data analysis and test verification show that when the minimum diameter of the air inlet hole 41 is greater than or equal to 0.2 mm, it can ensure that the air supply in the atomizing chamber 22 is sufficient and the suction resistance is appropriate.

If the contact angle between the liquid matrix stored in the atomizer 100 and the wall material of each component of the atomizer 100 currently used in the market is less than 90°, the liquid is infiltrated. For example, when the contact angle between the liquid matrix and the wall surface of the base 40 is less than 90°, it is infiltrating the liquid, which can increase its ability to adsorb on the wall surface.

Therefore, in the present application, the included angle a formed between the inner surface 410 defining the air inlet 41 and the first surface 430 is less than 90°, and the liquid matrix in the atomizer 100 leaking into the atomizing cavity 22 will escape from the second surface. When the surface 432 enters the air inlet 41, the liquid matrix is located on the inner surface 410 of the air inlet 41. Since the angle a formed between the inner surface 410 and the first surface 430 is less than 90°, the liquid matrix is difficult to expand from the inner surface 410. Infiltrating to the first surface 430 , thereby improving the anti-leakage capability of the air inlet 41 , and the air inlet 41 also has a capillary adsorption effect on the incoming liquid, which can further prevent the leakage of liquid from the air inlet 41 to the first surface 430 One side of the space leaks, which can significantly improve the anti-leakage capability of the base 40.

Referring to FIG. 5 , FIG. 5 is a first partial cross-sectional structural schematic diagram of the partition plate in the base shown in FIG. 4 . Specifically, the included angle a formed between the inner surface 410 and the first surface 430 is the included angle a at the junction of the inner surface 410 and the first surface 430 .

Alternatively, the diameter of the air inlet hole 41 decreases non-uniformly along the axis from the second surface 432 to the first surface 430 , so that the angle formed between the inner surface 410 and the first surface 430 is less than 90°.

In this embodiment, the air inlet hole 41 is a constricted hole along the direction from the second surface 432 to the first surface 430 , and has a strong liquid locking capability. However, the air intake hole of the base used in the existing atomizer is usually expanded in consideration of the draft angle, that is, the air intake hole is directed from the side toward the atomizing core to the direction away from the atomizing core along its own axis. The upper aperture gradually increases, which does not show the ability to lock fluid.

In the design process, the comparison experiments were carried out by designing shrinkage holes, equal diameter holes and expansion holes. The minimum diameters of the three hole types were all the same, and the same depth of liquid was set above the three hole types, and after the same After time, the liquid volume in each container located under the three hole types was detected, and the verification found that the liquid volume in the container located under the shrinking hole, the equal diameter hole and the expansion hole respectively increased in turn. The liquid locking capacity is greater than that of the equal diameter hole, and the liquid locking capacity of the equal diameter hole is greater than that of the expansion hole.

Therefore, in this embodiment, by setting the air intake hole 41 as a constricted capillary hole, and the angle formed between the inner surface 410 and the first surface 430 of the air intake hole 41 is less than 90°, the air intake hole 41 can be greatly increased.

The angle between the first surface 430 and the axis b of the air intake hole 41 is less than 90°, the air intake hole 41 is a through hole with a gradually increasing diameter in the direction from the second surface 432 to the first surface 430 , and the inner surface If the angle a formed between 410 and the first surface 430 is less than 90°, it is difficult for the infiltrating liquid to spread and infiltrate from the inner surface 410 to the first surface 430 , which can effectively improve the anti-leakage capability of the air inlet 41 .

In yet another embodiment, referring to FIG. 9 , FIG. 9 is a schematic diagram of a fifth partial cross-sectional structure of the partition plate in the base shown in FIG. 4 . The angle b between the first surface 430 and the axis of the air intake hole 41 is greater than 90°, wherein the angle b between the first surface 430 and the axis of the air intake hole 41 is the angle between the first line and the air intake hole 41 .
