The width of the reservoir 235 may be 0.1mm to 0.5mm, preferably 0.2mm to 0.4mm. The bottom surface of the flange portion 21 may be recessed upward to form a central through hole 212 communicating with the atomizing chamber 230, and the top surface of the through hole 212 protrudes from the bottom surface of the atomizing chamber 230 around the through hole, so that the leakage in the atomizing chamber 230 is not easy to enter the through hole 212, thereby reducing the risk of the leakage entering the power supply apparatus from the through hole 212. The protruding portion 23 has a slot 231 at each of two ends along the longitudinal direction for the two ends of the wick 31 to be respectively disposed therein.

The base 2 further has a second drain passage 242, a first drain passage 241, and a ventilation groove 243 formed therein. The second lower liquid channel 242 and the first lower liquid channel 241 respectively communicate two ends of the liquid suction core 31 with the liquid storage cavity 12, and the second lower liquid channel 242 and the first lower liquid channel 241 have different cross-sectional areas, so that the liquid discharge is smoother.

Liquid passageway 242 mainly used lower liquid under the second, liquid passageway 241 can be used to lower liquid and supplementary taking a breath under first, alleviates the dry combustion method that heating element 3 taken a breath not enough leads to, avoids the interior a large amount of bubbles that form of stock solution chamber. The height of the wall portion 24 may be 10mm or less, preferably 3mm. The outer side surface of the wall portion 24 is recessed inward to form a ventilation groove 243, and the ventilation groove 243 extends vertically downward from the upper end surface of the wall portion 24 to the rotation groove 222 and communicates with the rotation groove 222. The housing 1 is provided with an air inlet 11 communicated with the outside, and the air inlet 11 may be disposed and communicated with the vent groove 223 or disposed and communicated with one of the rotary grooves 222. The air inlet hole 11, the rotary groove 222 and the air exchange groove 243 are sequentially communicated to form an air exchange channel for communicating the liquid storage cavity 12 with the outside. As shown in fig. 7, when the air pressure in the reservoir 12 becomes low (e.g., when the electronic atomizer is transported by aircraft), the volume of the air bubbles in the reservoir 12 becomes large, and the liquid nebulizable substrate overflowing through the air purge slot 243 is contained in the spin tank 222, thereby improving leakage. As shown in fig. 8, when the air pressure in the reservoir 12 is returned to normal, the liquid nebulizable substrate stored in the spin tank 222 can flow back into the reservoir 12 through the air vent 243, thereby improving the negative pressure leakage.

The cross-sectional area of the second lower liquid channel 242 and the first lower liquid channel 241 is larger than that of the ventilation groove 243, so that the flow resistance of the liquid in the ventilation groove 243 is larger than that of the second lower liquid channel 242 and the first lower liquid channel 241, and the liquid nebulizable matrix in the liquid storage cavity 12 can be prevented from entering the ventilation groove 243. In some embodiments, the cross-sectional area of the air transfer slots 243 is in the range of 1mm or less ² Preferably 0.1mm ² (ii) a The first lower fluid passage 241 has a sectional area ranging from 1mm ² ～10mm ² Preferably 4.5 to 7.5mm ² 。

A first sealing part 42 surrounding the atomizing cavity 230 can be formed on the lower end face of the top seat 4, a second sealing part 232 in convex-concave fit with the first sealing part 42 is formed on the upper end face of the protruding part 23, and a first sealing structure is formed by convex-concave fit of the first sealing part 42 and the second sealing part 232, so that the liquid-state nebulizable substrate in the liquid storage cavity 12 can be prevented from entering the atomizing cavity 230 due to silica gel deformation, and liquid leakage can be prevented. In the present embodiment, the first sealing portion 42 is a protrusion with a semicircular cross section, and correspondingly, the second sealing portion 232 is a groove with a semicircular cross section. The bottom of the top seat 4 corresponding to the two slots 231 can also be extended downward to form two pressing parts 41, and the pressing parts 41 press the two ends of the wick 31 to form a second sealing structure.
