specific Embodiment approach
[0035] As a specific embodiment of the present invention, the side of the No. 2 water storage chamber 13 away from the No. 1 water storage chamber 12 is provided with a nozzle head 132 and a screw cap 133; One end of the nozzle 132 communicates with the No. 2 water storage chamber 13, and the other end is connected with the screw cap 133 by threads; the interlayer 14 is provided with a through hole 141; the through hole 141 connects the No. 1 water storage chamber 12 and the No. 2 storage chamber. The water chamber 13 is connected; when working, close the No. 1 seal 111 and the No. 2 seal 121, turn the position of the storage chamber 11 to the top of the No. 1 water storage chamber 12 and the No. 2 water storage chamber 13, turn the screw cap 133, open The nozzle head 132 is used to inject water into the No. 2 water storage chamber 13. After injecting 4 / 5 of the water, screw the screw cap 133 on the nozzle head 132 to close the No. 2 water injection chamber; by setting the nozz...
Embodiment approach
[0037] As a specific embodiment of the present invention, a flexible ball 122 is fixedly connected to the center of the inner wall of the No. 1 water storage chamber 12 and the No. 2 water storage chamber 13; when working, the material of the flexible ball 122 is preferably a sponge. Hands alternately press the two flexible balls 122, because the flexible balls 122 themselves have a supporting force, so that the water body will not be crushed or squeezed to break the seal; because the flexible balls 122 themselves have elasticity, they can be reset in time, so that when the No. 1 water storage Cavity 12 and No. 2 water storage chamber 13 leave sufficient reserved space when water is injected; Since the flexible ball 122 is made of sponge material, it can be flattened when it is under pressure, which is convenient for its transportation and sales.
