Alternatively, the first surface 430 may also protrude from a bottom surface of the bottom wall 42 opposite to the side of the connecting arm 44, which will not be described herein.
In the present application, the included angle a formed between the inner surface 410 of the air intake hole 41 and the first surface 430 is smaller than 90 °, and the air intake hole 41 has capillary adsorption effect on the entered liquid, in other words, the air intake hole 41 is a capillary hole. Wherein the external air flow passes through the air inlet holes 41 to enter from the side space of the first surface 430 to the side space of the second surface 432, in other words, the external air enters from the side space of the first surface 430 to the atomizing chamber 22 on the side of the second surface 432 through the air inlet holes 41.
Further, the air intake hole 41 is a capillary hole, and the aperture of the air intake hole 41 is 0.2mm or more and 4mm or less along the smallest section perpendicular to the axis of the air intake hole 41. The smaller the aperture of the air inlet hole 41 is, the larger the capillary adsorption force of the air inlet hole 41 to leaked liquid is, the better the leakage-proof effect is, and the data analysis and the test prove that when the minimum aperture of the air inlet hole 41 is smaller than or equal to 4mm, the capillary adsorption force of the air inlet hole 41 to leaked liquid is larger, and the leakage-proof effect is better. However, the air inlet 41 is also used for ventilation, so that the suction resistance is not too large, the air intake is difficult due to the too large suction resistance, the atomization cavity 22 is not fully fed, the atomization of the liquid matrix is insufficient, under the condition limitation, the data analysis and the test prove that the minimum aperture of the air inlet 41 is more than or equal to 0.2mm, the air supply in the atomization cavity 22 is ensured to be sufficient, and the suction resistance is proper.
The air intake hole 41 may be a circular hole, an elliptical hole, a polygonal hole, or the like in a section perpendicular to its own axis, and the aperture may be that of a circular hole, an elliptical hole, or a polygonal hole. For example, when the air inlet hole is a circular hole in a section perpendicular to the axis of the air inlet hole, the aperture is the diameter of the circular hole; or when the section of the air inlet hole along the axis perpendicular to the air inlet hole is an elliptical hole, the aperture is the major axis diameter and the minor axis diameter of the elliptical hole, and the major axis diameter and the minor axis diameter of the elliptical hole are required to meet the size limit; when the section of the air inlet hole perpendicular to the axis of the air inlet hole is a polygonal hole, the maximum aperture of the polygonal hole is smaller than or equal to 4mm, and the minimum aperture of the polygonal hole is larger than or equal to 0.2mm.
The liquid matrix stored in the atomizer 100 has a contact angle of less than 90 ° with the wall material of the components of the atomizer 100 currently used in the market, which is used as the immersion liquid. For example, when the contact angle between the liquid substrate and the wall surface of the base 40 is less than 90 °, the ability of the liquid substrate to adhere to the wall surface can be increased to infiltrate the liquid.
Therefore, in the present application, by defining the included angle a formed between the inner surface 410 of the air inlet hole 41 and the first surface 430 to be smaller than 90 °, when the liquid matrix leaked into the atomizing chamber 22 in the atomizer 100 enters the air inlet hole 41 from the second surface 432, the liquid matrix is located on the inner surface 410 of the air inlet hole 41, and because the included angle a formed between the inner surface 410 and the first surface 430 is smaller than 90 °, the liquid matrix is difficult to spread and infiltrate from the inner surface 410 to the first surface 430, so that the liquid leakage preventing capability of the air inlet hole 41 can be improved, and the air inlet hole 41 also has capillary adsorption effect on the entering liquid, so that leakage from the air inlet hole 41 to one side of the first surface 430 can be further prevented, and the liquid leakage preventing capability of the base 40 can be remarkably improved.
Referring to fig. 5, fig. 5 is a schematic view of a first partial cross-sectional configuration of a baffle plate in the base of fig. 4. Specifically, the angle a formed between the inner surface 410 and the first surface 430 is the angle a at the intersection of the inner surface 410 and the first surface 430. Specifically, a cross section is formed on the partition plate 43 through the axis of the air intake hole 41, the first surface 430 is formed with a first line on the cross section, the inner surface 410 is formed with a second line on the cross section, and an included angle a formed at the juncture of the first line and the second line is an included angle a formed between the inner surface 410 and the first surface 430, and the included angle a is smaller than 90 °.
In one embodiment, as shown in fig. 5, the first surface 430 is planar, the first surface 430 is perpendicular to the axis of the air intake hole 41, the angle b between the first surface 430 and the axis of the air intake hole 41 is 90 °, and the aperture of the air intake hole 41 gradually decreases along the axis and in a direction from the second surface 432 toward the first surface 430.
For example, the air inlet 41 is a tapered hole, the large end of the tapered hole is located on the second surface 432, the small end of the tapered hole is located on the first surface 430, and thus the aperture of the air inlet 41 is uniformly reduced along the axis from the second surface 432 to the first surface 430, the included angle a formed between the inner surface 410 of the tapered hole and the first surface 430 is smaller than 90 °, and the air inlet 41 is also a capillary hole, so that the leakage-proof capability of the air inlet 41 can be effectively improved.
Or the aperture of the air intake hole 41 may be unevenly reduced along the axis from the second surface 432 toward the first surface 430, such that the angle formed between the inner surface 410 and the first surface 430 is less than 90 deg..
In this embodiment, the air inlet hole 41 is a shrinkage hole along the direction of the second surface 432 pointing to the first surface 430, so that the liquid locking capability is high. Whereas the air inlet holes of the seats used in prior art atomizers are usually flared with respect to the draft angle, i.e. they gradually increase in diameter along their own axis from the side facing the atomizing core towards the side facing away from the atomizing core, they do not exhibit liquid locking capability.
In the design process, the comparison experiment is carried out by designing a shrinkage hole, an equal-diameter hole and an expansion hole, the minimum apertures of the three holes are the same, the liquid with the same depth is arranged above the three holes, after the same time, the liquid amount in each container respectively positioned below the three holes is detected, the liquid amount in the containers respectively positioned below the shrinkage hole, the equal-diameter hole and the expansion hole is verified to be sequentially increased, and the liquid locking capacity of the shrinkage hole is larger than that of the equal-diameter hole and is larger than that of the expansion hole.
Therefore, in the present embodiment, by setting the air intake hole 41 as a shrinkage capillary hole, and the included angle formed between the inner surface 410 and the first surface 430 is smaller than 90 °, the liquid locking capability of the air intake hole 41 can be greatly increased, and thus the leakage of liquid from the air intake hole 41 to the power supply 200 can be effectively prevented.
In another embodiment, as shown in fig. 6, fig. 6 is a schematic view of a second partial cross-sectional configuration of the baffle in the base of fig. 4. The included angle b between the first surface 430 and the axis of the air inlet 41 is smaller than 90 degrees, the air inlet 41 is a through hole with equal diameter, and the included angle a formed between the inner surface 410 and the first surface 430 is smaller than 90 degrees, so that the infiltration liquid is difficult to expand and infiltrate from the inner surface 410 to the first surface 430, and the leakage-proof capability of the air inlet 41 can be effectively improved.
The angle b between the first surface 430 and the axis of the air intake hole 41 is an angle b formed between the first line and the axis of the air intake hole 41 and facing the second surface 432.
Or as shown in fig. 7, fig. 7 is a schematic view of a third partial cross-sectional structure of the partition in the base of fig. 4. The included angle b between the first surface 430 and the axis of the air inlet hole 41 is smaller than 90 degrees, and the air inlet hole 41 is a through hole with gradually reduced aperture in the direction from the second surface 432 to the first surface 430, so that the included angle a formed between the inner surface 410 and the first surface 430 is smaller than 90 degrees, and the liquid leakage preventing capability of the air inlet hole 41 can be improved.
Or as shown in fig. 8, fig. 8 is a schematic view of a fourth partial cross-sectional structure of the partition in the base of fig. 4. The included angle between the first surface 430 and the axis b of the air inlet 41 is smaller than 90 degrees, the air inlet 41 is a through hole with gradually increased aperture in the direction from the second surface 432 to the first surface 430, and the included angle a formed between the inner surface 410 and the first surface 430 is smaller than 90 degrees, so that the infiltration liquid is difficult to expand from the inner surface 410 to the first surface 430, and the leakage-proof capability of the air inlet 41 can be effectively improved.
In yet another embodiment, referring to fig. 9, fig. 9 is a schematic view of a fifth partial cross-sectional configuration of a baffle in the base of fig. 4.
