The cover plate 191 is provided with an air inlet 1911, the adjusting valve body 193 covers the air inlet 1911, and the adjusting valve body 193 is in a closed state under normal conditions, that is, water in the accommodating cavity 11a is not allowed to come out, and atmospheric pressure is allowed to pass through when the pressure difference between the inside and the outside of the accommodating cavity 11a reaches a certain degree, so that the air pressure in the accommodating cavity 11a is balanced. The regulating valve body 193 does not allow water in the accommodating chamber 11a to pass therethrough, but the external atmospheric pressure can press and force it to open to form a gas-permeable state, such as a duckbill valve or the like.

Specifically, the regulating valve body 193 and the cover plate 191 are of an integrally formed structure. The adjusting valve body 193 is arranged on the surface of the cover plate 191 facing the accommodating cavity 11a and is of an integral forming structure with the cover plate 191, so that on one hand, the processing is convenient, and the working time and the cost are effectively saved by one-step forming through a die; on the other hand, the processing procedure of the product is simplified, the assembly is not needed, and the production efficiency of the water tank 10 is further improved. Meanwhile, the regulator valve body 193 is formed with an intake groove 1931 communicating with the intake port 1911, and a slit 1933 is formed in a groove wall of the intake groove 1931. This adjusting valve body 193 is formed with the inlet duct 1931 with air inlet 1911 intercommunication, can enlarge its surface area, and the lance 1933 forms on this inlet duct 1931's cell wall to can reduce the pressure of water to its impact, thereby avoid holding the water in the chamber 11a and open the lance 1933 at the in-process of rocking and take place to leak, effectively improved adjusting valve body 193's sealed effect. Meanwhile, the air inlet groove 1931 is communicated with the air inlet 1911, so that the atmospheric pressure can enter the air inlet groove 1931 through the air inlet 1911 for filling, and the slit 1933 is automatically opened to balance the atmospheric pressure when a certain amount of atmospheric pressure is reached, so that the effect of balancing the atmospheric pressure of the adjusting valve body 193 is not influenced.
