In an embodiment, as shown in
Specifically, as shown in
During use, an appropriate amount of water is added into the housing 1 first, and then the atomization assembly 3 is secured in the water tank 2. Then, there is no water in the water tank 2, the float 47 moves downward under its own gravity, the connecting lever 48 moves upward around the rotating shaft 49 so that the other end of the connecting lever tilts upward, and the pushing block 43 and pushing ball 45 move upward away from the water inlet 421, the spring 44 is stretched upward, water flows into the water tank 2 from the water inlet 421, and then a liquid level in the water tank 2 continuously rises. After liquid in the water tank 2 reaches a required height, the float 47 floats upward under the action of buoyancy of water, the connecting lever 48 moves downward around the rotating shaft 49 so that the other end of the connecting lever is pressed down, the pushing block 43 and the pushing ball 45 move downward close to the water inlet 421, and a spring force of the spring 44 pulls the pushing ball 45 to move downward, so that the pushing block 43 and the pushing ball 45 block and seal the water inlet 421 to prevent water flowing into the water tank 2.
