The water storage tank 2 is communicated with an external water source and is used for storing water used by the water using component. Both ends of the water guiding pipe 19 are respectively connected to the water storage tank 2 and the water using member, and a water inlet valve 18 capable of blocking or conducting the water guiding pipe 19 is disposed on the water guiding pipe 19 so as to allow water in the water storage tank 2 to flow into the water using member only when water needs to be introduced into the water using member. The water storage tank 2 comprises a tank body 21, and a water inlet pipe 22 and a water outlet pipe 23 which are communicated with the inside of the tank body 21, wherein the water inlet pipe 22 is communicated with an external water source, and the water outlet pipe 23 is communicated with a water using component through a water guide pipe 19. The box 21 includes two adjacent first lateral walls, second lateral wall, third lateral wall and fourth lateral wall in proper order, and first lateral wall can be any one lateral wall in the preceding lateral wall, back lateral wall, left side wall and the right side wall of box 21, and water inlet pipe mouth 22 sets up in the lower part of first lateral wall and is close to the second lateral wall setting with the form of going along the second lateral wall in the water outlet direction. In this case, the water outlet direction of the water inlet pipe 22 is approximately parallel to the second side wall, and the water inlet pipe 22 is disposed on the edge of the first side wall on the side intersecting the second side wall. When water enters the box body 21, the water flow is injected into the box body 21 through the water inlet pipe orifice 22 and flows forward along the second side wall (i.e. in a direction close to the third side wall), the flow inertia of the water flow and the reaction force of the water flow on the water flow generated by the second side wall after the water flow hits the second side wall cause the water flow to continue flowing along the second side wall until the water flow flows and hits the third side wall, the water flow rotates and flows along the third side wall and the fourth side wall along the first side wall under the action of the reaction force of the third side wall on the water flow and the flow inertia of the water flow, based on a similar principle, the water flow forms a vortex flow under the driving of the flow inertia and the reaction force of each side wall of the box body 21 on the water flow, the water level in the box body 21 continuously rises with the continuous water injection of the water inlet pipe orifice 22, and the rotation range of the vortex flow formed in the box body 21 gradually increases from bottom to top, the flow effect becomes increasingly stronger.
