The water level in the annular space is lowered along with the increase of the air in the annular space, and then the water level in the annular space is raised. Meanwhile, as the air in the water storage bin 203 decreases, the air pressure in the water storage bin 203 decreases, and thus the air and water in the space outside the ring can be driven to enter the water storage bin 203 unidirectionally through the water guide pipe 212 and the first one-way valve 204.

It should be noted that, as the water level in the space outside the ring increases, air in the space outside the ring first enters the water storage tank 203 unidirectionally via the water guide pipe 212 and the first check valve 204. When the water level in the outer space rises to the lower port of the water guide pipe 212, the water in the outer space can start to enter the water storage bin 203 unidirectionally through the water guide pipe 212 and the first one-way valve 204 for temporary storage.
