Description

Push-pull shunt valve structure and shower system Technical Field The utility model relates to the technical field of water diversion valves, in particular to a push-pull water diversion valve structure and a shower system. Background The shunt valve is a valve body structure capable of controlling the trend of a waterway, for the existing shunt valve, waterway switching is usually realized by pushing a piston in the shunt valve, but the piston is easily influenced by water pressure, so that the thrust required by pushing the piston to move is large, and the operation is not labor-saving and inconvenient. Disclosure of utility model The present utility model aims to solve the technical problems in the prior art described above. Therefore, the utility model provides the push-pull water diversion valve structure and the shower system, the piston is less influenced by water pressure, and the thrust required for the piston is smaller. According to an embodiment of the first aspect of the present utility model, a push-pull diverter valve structure includes: The valve body is internally provided with a water diversion cavity, a first water outlet, a water inlet and a second water outlet which are communicated with the water diversion cavity are formed in the peripheral wall of the valve body, the first water outlet, the water inlet and the second water outlet are sequentially arranged along the axial direction of the valve body, and one end of the valve body along the axial direction of the valve body is also provided with a mounting port communicated with the water diversion cavity; The fixed cylinder is inserted into the water diversion cavity through the mounting opening, the peripheral wall of the fixed cylinder is in sealing fit with the inner wall of the water diversion cavity, the peripheral wall of the fixed cylinder is provided with an avoidance hole, and the peripheral wall of the fixed cylinder is also provided with a water passing port corresponding to the first water outlet; The piston is arranged in the water diversion cavity and can move along the axial direction of the valve body, the piston comprises a water diversion part, the water diversion part is positioned between the first water outlet and the second water outlet, a water diversion sealing piece is arranged on the peripheral wall of the water diversion part, when the water diversion sealing piece is abutted with the inner peripheral wall of the fixed cylinder, the water diversion part cuts off the water inlet from the first water outlet, when the water diversion sealing piece is abutted with the inner peripheral wall of the valve body, the water diversion part cuts off the water inlet from the second water outlet, and when the water diversion sealing piece is positioned at the water inlet, the water inlet is communicated with the second water outlet and the second water outlet; The push button is fixedly connected with the piston so as to drive the piston to move, and the push button penetrates through the avoidance hole.
