According to the scheme, the conical part extends into the lower vent hole 112 to serve as the guide of the plug 114, so that the defect that gas cannot be discharged timely when the plug 114 is blocked in operation in the guide groove due to the fact that the guide groove is formed above the plug 114 in the conventional structure is overcome. When the water tank 1 is poured, water enters through the lower vent hole 112, the plug 114 is pushed to move towards the air guide column 116, the plug 114 is plugged on the air guide column 116 because the viscosity and resistance of the water are greater than those of the air, the water cannot enter the air guide column 116, and therefore the water cannot flow out of the upper vent hole 113.
Preferably, the top of the cover 11 is provided with a handheld part 118 higher than the plane of the cover, and the top surface of the handheld part 118 is ridge-shaped; the upper vent 113 is disposed on a top surface of the handle 118.
