Wherein the ventilation groove 62 is communicated with the liquid storage cavity 4 and the cavity 61, and the air inlet 63 is communicated with the cavity 61 and the outside.
When a user sucks, the air pressure in the atomization cavity is negative pressure, and the air enters the atomization cavity from the air inlet channel 100, and the control circuit starts the heating plate to atomize the liquid medium adsorbed in the porous ceramic body. The liquid medium of the porous ceramic body is reduced, and the porous ceramic body sucks oil from the liquid storage cavity 4 under the action of capillary force, and then atomization is continued. The liquid medium in the liquid storage cavity 4 is reduced, the gas space is increased, the air pressure in the liquid storage cavity 4 is excessively negative pressure, air enters the cavity 61 from the air inlet 63 of the shell, and then enters the liquid storage cavity 4 through the ventilation groove 62, so that the gas-liquid balance is realized, and the speed of the liquid discharge is matched with the atomized speed of the liquid medium.

Referring to fig. 8a to 8c, the smoke liquid, which enters the cavity 61 through the ventilation groove 62, of the liquid storage chamber 4 due to capillary force is adsorbed on the top of the inverted V shape, thereby being stored in the cavity 61. When the user sucks, the liquid in the liquid storage cavity 4 is reduced, the air pressure is reduced, and the tobacco tar adsorbed on the top of the inverted V shape flows back into the liquid storage cavity 4 from the ventilation groove 62. The inverted V-shaped structure design can prevent tobacco tar from flowing out of the shell on one hand, and can enable the tobacco tar at the bottom of the cavity 61 to flow back to the liquid storage cavity 4 along the inverted V-shaped structure on the other hand. Wherein a in fig. 8a-8c is the adsorption amount of the smoke liquid adsorbed on the top of the inverted V shape in different cases, specifically:
fig. 8a shows that when the internal pressure of the liquid storage cavity 4 is the same as the external pressure in the rest state, the tobacco tar forms an oil film at the ventilation groove 62 to generate tension so as to lock the liquid, and the tobacco tar is in a vapor-liquid equilibrium state.
In fig. 8b, when the external environment changes, for example, an external negative pressure appears, and the internal pressure of the liquid storage cavity 4 is greater than the external pressure, the smoke liquid further leaks from the ventilation groove 62 to the cavity 61, and the cavity 61 is in an inverted V-shaped structure, so that the smoke liquid is pulled by the maximum capillary force and tension at the center crack of the cavity 61, thereby realizing the liquid locking function. The lower the capillary force and the tension, the smaller the traction of the tobacco tar until the tension is cut off, and at the moment, a small part of tobacco liquid can stay on the annular boss 116, and the tobacco liquid is prevented from flowing out of the air inlet 63 through the annular boss 116.
Fig. 8c shows that when the liquid medium in the liquid storage cavity 4 is reduced, the gas space is increased, the air pressure in the liquid storage cavity 4 is excessively high, and when the internal pressure of the liquid storage cavity 4 is smaller than the external pressure, the external pressure breaks through the tension of tobacco tar at the ventilation groove 62, so that external air enters the liquid storage cavity 4, and ventilation operation is completed. Meanwhile, tobacco tar adsorbed at the top of the inverted V shape can be squeezed back into the liquid storage cavity 4, so that liquid leakage recycling is realized.
In some embodiments, the ventilation groove 62 is formed on the upper housing 11 or on the housing 3 where the top of the inverted circular truncated cone-shaped outer peripheral surface abuts the cylindrical inner peripheral surface. In the present embodiment, the ventilation groove 62 is formed in the upper housing 11 where the top of the inverted circular truncated cone-shaped outer peripheral surface abuts against the cylindrical inner peripheral surface.

Preferably, the top opening of the ventilation slots 62 is 1.0mm by 0.3mm in size.
In some embodiments, the air inlet 63 is disposed up and down and offset from the air exchange slots 62 in the circumferential direction. Preferably, in this embodiment, in order to further avoid the flow of the smoke liquid from the air inlet 63, the air inlet 63 and the air exchanging groove 62 are arranged opposite to each other in the circumferential direction, and the liquid medium enters from the air exchanging groove 62 to the air inlet 63 and flows out by a distance of half a cycle, so that the flow of the smoke liquid can be prevented to the maximum extent.
