In this embodiment, as shown in fig. 5 and 6, the air compression tank 2 includes a valve core 21 and a valve body, the valve core 21 is disposed through the valve body, an air outlet 22 is disposed on the valve core 21, an air outlet 23 is disposed on the valve body, when the atomizing cup 1 is connected to the compressed air tank 2, the lower end of the air flow nozzle 14 of the atomizing cup 1 is hermetically connected to the valve core 21 of the compressed air tank 2, and the valve core 21 is pressed down, so that the air outlet 22 on the valve core 21 is communicated with the air outlet 23 on the valve body, and compressed air is discharged from the valve core 21 and enters the atomizing cup 1; after the atomizing cup 1 and the compressed air tank 2 are separated, the valve core 21 returns under the action of the spring 24, the air outlet 22 is separated from the air outlet 23, and the release of air is stopped.
Further, as shown in fig. 5 and 6, the atomizing cup 1 and the compressed air tank 2 are connected by a snap.
In this embodiment, as shown in fig. 5 and 6, a buckle is designed below the atomizing cup 1, which can clamp the edge of the valve seat of the compressed air tank 2, and the disassembly is convenient.
The present invention has been explained by using specific embodiments, and the explanation of the above embodiments is only used to help understand the method and the core idea of the present invention; meanwhile, for the general technical personnel in the field, according to the idea of the present invention, there are changes in the specific implementation and application scope, to sum up, the content of the present specification should not be understood as the limitation of the present invention.
