[0048] See also Figure 4 , is a schematic structural diagram of a limiting member of the first embodiment of the electronic atomization device provided by the present invention.

[0049] The limiter 12 is used to clamp the removable insert 3. An insertion groove 131 is formed in the first movable member 13, and the removable insert 3 is at least partially accommodated in the insertion groove 131. After the removable insert 3 is inserted into the first movable member 13, the movement of the removable insert 3 is limited by the limiter 12. By arranging the limiter 12 on the inner wall of the housing 10, the limiter 12 clamps the removable insert 3, so that the friction force on the removable insert 3 is equal to the upward rebound force on the removable insert 3, so that the removable insert 3 does not slide after being inserted into the insertion groove 131. The rebound force on the removable insert 3 can be provided by the first movable member 13.

[0050] The limiting member 12 includes a fixing portion 121 and a clamping portion 122. The fixing portion 121 is arranged around the periphery of the removable insert 3.

The diameter of the circle formed by the bulges of the ends of the four convex strips away from the fixing portion 121 as the endpoints is slightly smaller than the diameter of the removable insert 3, so as to provide friction to the removable insert 3.

[0052] In another embodiment, the limiting member 12 is not provided in the atomizer assembly 1 , and the fixing of the detachable insert 3 after being inserted into the insertion slot 131 is achieved by interference fit between the detachable insert 3 and the side wall of the insertion slot 131 .

[0053] See also Figure 5 and Figure 6 , Figure 5 is a partial schematic diagram of a power supply assembly of the first embodiment of the electronic atomization device provided by the present invention, Figure 6 It is a schematic structural diagram of the second moving part of the first embodiment of the electronic atomization device provided by the present invention.

[0054] In the first embodiment, the power supply assembly 2 further includes a second moving member 25.

The switch 231 is disposed at an end of the second moving member 25 away from the atomizer 11.

[0055] The second movable member 25 is in pin-like contact with the atomizer 11, and the movement of the atomizer 11 causes the second movable member 25 to trigger the switch 231. When the atomizer 11 contacts the second movable member 25 and applies pressure to the second movable member 25, the second movable member 25 moves toward the direction close to the switch 231 under the pressure from the atomizer 11, triggering the switch 231, and the switch 231 is in the first state, that is, the detection circuit 23 is in the first state. When the pressure of the atomizer 11 on the second movable member 25 is cancelled or is less than the resilience of the second movable member 25, the second movable member 25 is separated from the switch 231, and the switch 231 is in the second state, that is, the detection circuit 23 is in the second state. In other embodiments, when the detection circuit 23 is in the first state or the second state, that is, the switch 231 is in the first state or the second state, the second movable member 25 maintains contact with the switch 231, and the switch 231 is in a triggered state, but the conduction level of the detection circuit 23 when the switch 231 is in the first state is different from the conduction level of the detection circuit 23 when the switch 231 is in the second state.

[0056] The second moving member 25 includes a snap-fitting portion 251, an elastic portion 252, a receiving portion 253, and a moving rod 254. The receiving portion 253 is a hollow cylinder, and an elastic member 2531 is arranged inside the receiving portion 253, so that the second moving member 25 can be deformed and can be restored to its original state. A convex strip is arranged at one end of the receiving portion 253 to form a snap-fitting portion 251, and the extension direction of the snap-fitting portion 251 is perpendicular to the extension direction of the receiving portion 253; the snap-fitting portion 251 is used to snap the second moving member 25 on the connecting seat 24. An elastic portion 252 is arranged at one end of the receiving portion 253 close to the snap-fitting portion 251, and the elastic portion 252 is used to contact the atomizer 11, and the elastic portion 252 can shrink and drive the elastic member 2531 to deform and restore to its original state. At least part of the moving rod 254 is accommodated in the receiving portion 253, and the elastic member 2531 in the receiving portion 253 can drive the moving rod 254 to move. After being subjected to force, the elastic part 252 moves toward the direction close to the moving rod 254, and the elastic part 252 drives the elastic member 2531 to deform toward the direction close to the moving rod 254, and the elastic member 2531 drives the moving rod 254 to move away from the elastic part 252; that is, the movement direction of the moving rod 254 is the same as the movement direction of the elastic part 252.

[0057] In this embodiment, the second moving member 25 is an integrated spring pin structure. In another embodiment, the second moving member 25 can be other structures, as long as the second moving member 25 can trigger the switch 231 and change the state of the switch 231. The second moving member 25 can be a hardware part or made of other materials such as silica gel, whichever meets the needs.

[0058] The power supply assembly 2 further includes an abutment member 26. The abutment member 26 is fixed to an end of the second movable member 25 away from the atomizer 11 by means of a snap fit. For example, a convex strip may be provided on the second movable member 25, and a card slot may be provided on the abutment member 26; or a convex strip may be provided on the abutment member 26, and a card slot may be provided on the second movable member 25. The abutment member 26 may be made of silica gel, foam, foamed rubber or other elastic materials; the shape and size of the abutment member 26 are not limited and may be designed as required.

[0059] By providing an abutment member 26 at one end of the second movable member 25 away from the atomizer 11, and the abutment member 26 is fixedly connected to the second movable member 25, the contact area with the switch 231 is increased, so that a slight misalignment of the second movable member 25 during installation will not affect the triggering of the switch 231 by the second movable member 25, thereby improving the stability of detecting the insertion state of the removable insert 3 in the electronic atomization device.

[0060] In other embodiments, the abutment member 26 may not be provided at the end of the second movable member 25 away from the atomizer 11 , and the second movable member 25 directly triggers the switch 231 . The movement of the second movable member 25 can change the state of the switch 231 , and the state of the detection circuit 23 can be changed.

[0062] The electronic atomization device further includes an airflow sensor 4 and a display light 5. The airflow sensor 4 is used to detect airflow changes in the electronic atomization device. The display light 5 prompts the user according to the signal received by the controller 22.

[0063] The airflow sensor 4 in the electronic atomization device determines whether the user is inhaling by detecting the change in air pressure. The controller 22 is also used to determine whether the number of air pressure changes in the electronic atomization device reaches a preset value based on the air pressure change detected by the airflow sensor 4. If the preset value is reached, the display light 5 set on the electronic atomization device reminds the user to replace the detachable insert 3. Among them, the airflow sensor 4 uses a microphone, and other components can also be used, as long as it can detect the change in air pressure.
