The liquid locking piece 5 is provided with a liquid inlet 501 communicated with the liquid supply channel 201 and a liquid locking groove 502 communicated with the liquid suction surface 401; a liquid-locking gap 503 for communicating the liquid inlet 501 and the liquid-locking groove 502 is formed between one end of the liquid-locking material 5 facing the heating element 4 and the liquid-absorbing surface 401 of the heating element 4. The cross-sectional area of the lock liquid tank 502 gradually decreases in the direction toward the suction surface 401.

In the atomizer 10, the liquid locking piece 5 is arranged above the liquid suction surface 401 of the heating body 4, the liquid inlet 501 communicated with the liquid supply channel 201 and the liquid locking groove 502 communicated with the liquid suction surface 401 are arranged on the liquid locking piece 5, and a liquid locking gap 503 communicated with the liquid inlet 501 and the liquid locking groove 502 is formed between one end of the liquid locking piece 5 facing the heating body 4 and the liquid suction surface 401 of the heating body 4; when the atomizer 10 is placed in the forward direction, the liquid in the liquid storage cavity 101 flows to the heating element 4 through the liquid supply channel 201 on the upper atomizing base 2, the liquid inlet 501 on the liquid locking piece 5 and the liquid locking gap 503 under the action of gravity, and is retained in the liquid locking groove 502 above the heating element 4; when the atomizer 10 is inclined or inverted, although the liquid in the liquid storage cavity 101 cannot flow to the liquid absorption surface 401 of the heating element 4, the liquid absorption surface 401 of the heating element 4 can still absorb the liquid retained in the liquid locking groove 502 under the capillary force, thereby avoiding the problems that the heating element 4 is burnt and scorched, and even the heating element on the heating element 4 is burnt.

Specifically, the liquid locking groove 502 includes a lower end opening and an upper end opening at two opposite ends, and the lower end opening is closer to the liquid suction surface 401 than the upper end opening; the cross-sectional area of the locking fluid slot 502 is gradually reduced in the direction extending from the upper end opening to the lower end opening. This arrangement can increase the capillary force of the liquid in the liquid lock tank 502, and contributes to the flow of the liquid in the liquid lock tank 502 to the liquid absorbing surface 401 of the heating element 4 by the capillary force. In an alternative embodiment, the liquid locking groove 502 may also be a structure with an open lower end and a closed upper end.

The fins 504 are arranged at intervals, so that bubbles generated on the liquid suction surface 401 of the heating body 4 can be discharged, and a larger liquid inlet area can be obtained.

Specifically, the distance of the liquid locking gap 503 in the direction of the line connecting the liquid locking member 5 and the liquid absorption surface 401 is 0.5 to 1.0 mm. The height of the liquid-locking gap 503 is considered from the installation angle, and if the height of the liquid-locking gap 503 is less than 0.5mm, the liquid-locking member 5 is likely to collide with the liquid-absorbing surface 401 to block part of the liquid-absorbing passage 403 during installation, and the thin heating element 4 is also likely to be crushed. When the height of the lockup gap 503 is larger than 1.0mm, bubbles tend to grow in the lockup gap 503, and block the liquid absorbing surface 401 of the heating element 4.

Specifically, the depth of the liquid locking groove 402 is 0.1-0.6 mm, and the width of the liquid locking groove 402 at the lower opening is 0.1-0.5 mm; in the extending direction from the upper end opening to the lower end opening, the opening angle of the locking fluid groove 402 ranges from 3 degrees to 15 degrees.

In other embodiments, the two fins 504 corresponding to the two long side walls 506 are integrally connected, and the distance of the lockup gap 503 in the direction of the line connecting the lockup member 5 and the liquid absorbing surface 401 is 0.4 to 1.5 mm. By such an arrangement, the requirement for the distance of the locking fluid gap 503 can be reduced, the distance of the locking fluid gap 503 can be selected in a relatively wider range, and more fluid can be retained in the locking fluid groove 502.

The present application further provides an electronic atomising device comprising a power supply and an atomiser 10 connected to one another, the power supply being arranged to power the atomiser such that the atomiser 10 is able to atomise a liquid substrate to form an aerosol.

To sum up, according to the atomizer and the electronic atomizing device provided by the present application, the liquid locking piece 5 having the liquid locking groove 502 is disposed above the liquid absorbing surface 401 of the heat generating body 4, and the liquid locking gap 503 is formed between the liquid locking piece 5 and the liquid absorbing surface 401 of the heat generating body 4, when the atomizer 10 is inclined or inverted, the liquid is cut off in the liquid locking gap 503, so as to lock the liquid in the liquid locking groove 502, the liquid absorbing surface 401 of the heat generating body 4 can absorb the liquid in the liquid locking groove 502, and the problems that the heat generating body 4 burns to generate scorched smell and even burns off the heating element on the heat generating body 4 are avoided.
