The flow opening 1125 is opened at the middle position of the paddle 1121, so that the water flows mutually up and down the paddle 1121, and the turbulence resistance is increased.

Preferably, the paddle 1121 has a circular disk structure, and the paddles 1122 are arranged at equal angles along the outer circumference of the paddle 1121. The paddle 1121 has a circular disk structure, and the paddles 1122 are arranged at equal angles along the outer circumference of the paddle 1121. Thus, the effect of water flow impacting the blade surfaces of the blades 1122 is better, and water resistance is increased.

It should be noted that, according to the design concept described above, a person skilled in the art can also use other types of water-resistant water tanks 110, including but not limited to the water-resistant water tank 110 type provided by the above preferred embodiment.
