Manual sand cylinder changeover valves generally comprise: the sealing device comprises main parts such as a sealing space ring, a valve core, a return spring, a valve cover and a handle, for example, Chinese patent CN 201620420211.5. When a user uses the product to switch stations, firstly, a water source of a water inlet is closed, then the handle is pressed downwards by force, at the moment, the valve core is separated from the sealing space ring to rotate the valve core, then the valve core is driven to rotate by rotating the handle, when an indication point on the handle corresponds to a certain function partition on the top surface of the valve cover, the force for pressing the handle downwards is released, and the specified function can be realized.
Although the function of the utility model is perfect, the use requirement of the user can be well satisfied. However, the method has the disadvantages that the water source of the water inlet is required to be closed when the station is switched, and the 'handle' is required to be pressed downwards forcibly to separate the 'valve core' from the 'sealing space ring', so that the 'valve core' can be rotated. Along with improvement and improvement of living conditions of people, the demand of the sand cylinder change-over valve is higher and higher, the sand cylinder change-over valve with the structure of the return spring is not only complex in structure, but also higher in production cost, for example, the full-automatic sand cylinder change-over valve is more obvious, so that the sand cylinder change-over valve is inconvenient to popularize.

The station can be switched under the condition that a water source of a water inlet is not required to be closed, and a complex structure of a return spring is avoided.
In order to achieve the purpose, the utility model provides a sand cylinder change-over valve which comprises a valve body, a movable valve plate, a fixed valve plate, a shifting fork and a driving device for controlling the rotation of the movable valve plate, wherein the fixed valve plate is fixed in the valve body, the movable valve plate driven by the driving device is in rotary sealing fit with the fixed valve plate, and the sand cylinder change-over valve is provided with a water inlet, a water outlet, a filter element upper connector and a filter element lower connector; the rotary radius outside the fixed valve plate is provided with four through holes and a blind hole, the first through hole is communicated with an upper connector of the filter element, the second through hole is communicated with a water outlet, the third through hole is communicated with a lower connector of the filter element, the fourth blind hole is not communicated with the valve body, the fifth through hole is communicated with a water outlet on the valve body, and the first through the fifth holes are sequentially arranged and adjacent to each other; the movable valve plate is provided with a water inlet through hole which is normally communicated with a water inlet on the valve body, and an arc-shaped conduction blind hole.
Furthermore, the driving can adopt a manual or electric driving mode to drive the movable valve plate to rotate.
Further, the matching relationship of the movable and fixed valve plates comprises: the water inlet through hole is communicated with the first through hole, and the arc-shaped conduction blind hole conducts the second through hole with the third through hole; the water inlet through hole is communicated with the third through hole, and the first through hole is communicated with the fifth through hole through arc-shaped conduction; the water inlet through hole is communicated with the first through hole, and the arc-shaped conduction blind hole conducts the third through hole with the fifth through hole; the water inlet through hole is communicated with the second through hole, and the arc-shaped conduction blind hole is communicated with the first through hole and the fifth through hole; the water inlet through hole is communicated with the fourth blind hole, and the arc-shaped conduction blind hole conducts the first through hole with the second through hole; the water inlet through hole is communicated with the fifth through hole, and the first through hole, the second through hole and the third through hole are communicated through the arc-shaped communication blind hole.
