For example, when the liquid substrate in the liquid storage chamber 120 is consumed, if the liquid substrate in the liquid storage chamber 120 cannot be supplemented with gas, the air pressure in the liquid storage chamber 120 will be continuously reduced, and when the air pressure in the chamber is reduced to a certain degree, the liquid substrate cannot be discharged smoothly, so that the atomizing core 30 cannot be sufficiently supplied with liquid, which is likely to generate scorched smell and reduce the atomizing efficiency, and finally brings a poor smoking experience to a user. Alternatively, when the atomizing core 30 atomizes the liquid substrate, the air in the reservoir 120 is heated to increase the air pressure in the reservoir, and the excessive air pressure in the reservoir 120 may cause the liquid substrate to leak out, which increases the failure rate of the electronic atomizing device 300.

In this embodiment, as shown in fig. 8 to 10, a gas exchange groove 232 is disposed on one side of the partition 23 facing the atomizing chamber 210, the gas exchange groove 232 communicates with the liquid inlet 230 and the atomizing chamber 210, and the sealing member 55 covers the gas exchange groove 232, such that one end of the gas exchange groove 232 communicates with the liquid inlet 230 and the other end communicates with the atomizing chamber 210.

The aeration tank 232 may be provided to be wound around the partition 23 to increase the length of the aeration tank 232 itself and to increase the space in which the liquid substrate can be stored.

The number of the ventilation slots 232 is not limited in the present application.

Further, a buffer groove 234 is further arranged on one side of the partition plate 23, which is away from the liquid storage cavity 12, the air exchange groove 232 flows through the buffer groove 234, and the sectional area of the buffer groove 234 along the path direction of the air exchange groove 232 is larger than that of the air exchange groove 232 in the same direction. The buffer tank 234 is used for buffering the liquid substrate, and the buffer tank 234 can accommodate more liquid substrates, so that the liquid storage capacity of the ventilation tank 232 can be improved, and the liquid substrates can be prevented from leaking from the ventilation tank 232.

Through research, the depth of the ventilation slot 232 is set to be 0.1mm to 0.5mm, the width of the ventilation slot 232 along the direction perpendicular to the path direction thereof is set to be 0.1mm to 0.5mm, the width of the buffer slot 234 is greater than or equal to the width of the ventilation slot 232, and the depth of the buffer slot 234 is greater than the depth of the ventilation slot 232.

When the cross-sectional dimension of the ventilation groove 232 perpendicular to the path direction is within the above-mentioned dimension range, ventilation can be smooth, and the surface adsorption force of the ventilation groove 232 on the liquid substrate is appropriate, so that the liquid substrate in the liquid storage cavity 120 can be well adjusted in the ventilation groove 232, and liquid leakage is not easy to occur. When the depth of the air exchanging groove 232 is less than 0.1mm or the width of the air exchanging groove 232 is less than 0.1mm, the adsorption force of the air exchanging groove 232 to the liquid substrate is too large, so that air exchanging is difficult, and the air pressure adjustment in the liquid storage cavity 120 is not facilitated. When the depth of the ventilation groove 232 is greater than 0.5mm or the width of the ventilation groove 232 is greater than 0.5mm, the adsorption force of the ventilation groove 232 on the liquid matrix is too small, and the liquid matrix is easily leaked by the ventilation groove 232.

The ports of the air exchanging groove 232 communicated with the liquid inlet hole 230 are arranged in different positions, so that the phenomenon that bubbles generated by the two ports at the same position are polymerized to increase the liquid discharging difficulty of the liquid matrix can be avoided.

Further, referring again to fig. 9 and 10, the inner sidewall of the atomizing chamber 210 is further provided with a guide groove 211, and the guide groove 211 is communicated with the ventilation groove 232 so that even if the liquid substrate leaks a little along the ventilation groove 232, the leaked liquid substrate can be gathered toward the liquid collecting groove 417 along the guide groove 211 and the liquid guide groove 434 to prevent the leaked liquid from splashing freely.

Alternatively, the seal member 55 may be provided with the above-described scavenging groove 232 and the buffering groove 234, and the partition plate 23 may be provided without the scavenging groove 232 and the buffering groove 234. Alternatively, the partition 23 and the sealing member 55 are each provided with a part of the ventilation groove 232 and the buffer groove 234, and the partition 23 and the sealing member 55 cooperate with each other to form the ventilation groove 232 and the buffer groove 234, which is not particularly limited in the present application.
