Preferably, the elastic member 92 is a spring, and the spring extends along the axial direction of the water guide channel 10; one end of the spring is fixedly connected with the inner wall of the water guide channel 10 directly or indirectly through a bracket, and the other end of the spring is fixedly connected with the valve core 91 so that the valve core 91 is acted by centrifugal force

In the embodiment of the present invention, a gap for ensuring water flow to pass through is formed between the elastic member 92 and the inner wall of the water guide channel 10, so as to ensure that after the valve core moves by centrifugal force to open the water guide channel 10, the water flow flows along the water guide channel, passes through the gap on the periphery of the elastic member, and flows out from the water outlet end.

In the embodiment of the invention, the first side of the valve core 91 is correspondingly contacted with the outer wall surface of the side wall 101 of the inner cylinder in an attaching manner, and the second side of the valve core 91 is correspondingly contacted with the side of the water guide channel 10 far away from the inner cylinder in an attaching manner. Therefore, one side of the valve core, which faces the axis of the inner cylinder, is arranged in parallel with the side wall of the inner cylinder correspondingly, after the valve core correspondingly blocks the water guide channel, the first side is correspondingly attached and contacted with the outer wall surface of the side wall of the inner cylinder, and surface contact with better sealing performance is formed, so that the sealing performance of the centrifugal valve when the water guide channel is blocked is improved.

In the embodiment of the present invention, in order to improve the smoothness of the movement of the valve core 91, the following arrangement may be made: the first side of the valve core 91 and the side wall 101 of the inner cylinder are parallel planes, and the second side of the valve core 91 and the side of the water channel 10 far away from the inner cylinder are inclined planes with the same slope and parallel. Therefore, when the valve core of the centrifugal valve is acted by the centrifugal force generated by the rotation of the inner cylinder, the valve core slides smoothly along the joint of the second side and the inner wall of the water guide channel; meanwhile, because the second side of the valve core and the inner wall surface of the water guide channel form a parallel surface, the friction is reduced in the sliding process of the valve core, and a guide effect is provided for the movement of the valve core.
