[0078] During operation, after the atomized liquid enters the air replenishing flow channel 2311 from the liquid storage cavity, it flows along the air replenishing flow channel 2311 towards the air inlet end of the atomization component 3, and then enters the atomization component 3 from the air inlet end of the atomization component 3. The atomized liquid flows in the direction shown by the blue dotted arrow in Figure 9 , thereby achieving the replenishment of the atomized liquid to the atomization component 3 and improving the wetting efficiency of the atomization component 3; at the same time, the gas replenished at the air outlet end of the atomization component 3 flows into the air replenishing channel 231 along the air guiding groove 3221 and uniformly diffuses to the liquid storage cavity through the air replenishing channel 231. The replenished gas flows in the direction shown by the red dotted arrow in Figure 3 , making the replenished bubbles more evenly diffuse from the side wall and bottom of the atomization component 3 into the liquid storage cavity, thereby achieving the air pressure balance inside the electronic atomization device, improving the air pressure balance inside the electronic atomization device, improving the liquid guiding efficiency, and achieving the improvement of the atomization efficiency and atomization quality of the electronic atomization device.

[0079] Please refer to Figure 10 and Figure 11 As shown, in other embodiments, the air replenishing channel 231 can also be set to include three air replenishing flow channels 2311.

[0080] During operation, the atomized liquid enters the supplementary air flow channel 2311 from the liquid storage chamber, flows along the supplementary air flow channel 2311 to the air inlet end of the atomizing assembly 3, and then enters the atomizing assembly 3 from the air inlet end of the atomizing assembly 3. Figure 11 The blue dotted arrow in the figure flows in the direction indicated by the blue dotted arrow, thereby replenishing the atomized liquid into the atomizing component 3, thereby improving the infiltration efficiency of the atomizing component 3; at the same time, the gas replenished at the gas outlet end of the atomizing component 3 flows into the gas replenishing channel 231 along the gas guide groove 3221, and is evenly diffused to the liquid storage cavity through the gas replenishing channel 231.

When the liquid-absorbing component 22 is installed on the base 21, the electrical connector 25 is at least partially placed in the hollow groove 221, and the outer wall of the electrical connector 25 contacts the arc-shaped groove, which can further improve the limiting and fixing effect of the liquid-absorbing component 22.

[0103] In some embodiments, the liquid absorbing member 22 may adopt a porous structure, and the porous structure can achieve good liquid absorbing effect.

[0104] In some embodiments, the pore size of the liquid absorbent member 22 is 100 μm to 200 μm. Preferably, the pore size range of the liquid absorbent member 22 is set to 100 μm to 150 μm.

In this embodiment, the porosity of the liquid-absorbing member 22 is set to 65%.

[0106] The embodiment of the present application sets the pore size and porosity of the liquid absorbent member 22, thereby ensuring that the liquid absorbent member 22 can perform a good liquid absorption function while maintaining a certain structural strength, thereby providing stable support for the sealing member 23 and improving the structural stability of the base assembly 2.
