Pulsation flushing device for intelligent closestool

The pulsating flushing device comprises a base and a shell, the base is fixedly connected with the shell, a three-way transfer piece is fixedly connected between the base and the shell, a piston capable of doing reciprocating motion is arranged on the left side of the three-way transfer piece, and the piston is provided with an eccentric wheel mechanism driving the piston to move. A water inlet assembly is arranged at the upper end of the three-way transfer part and connected with a water source, a water outlet assembly is arranged on the right side of the three-way transfer part, and the piston, the water inlet assembly and the water outlet assembly are communicated and combined to form a water storage cavity. The pulse flushing device has the advantages that the design is ingenious, the structure is reasonable, the piston is driven by the eccentric wheel mechanism to achieve reciprocating motion, the eccentric wheel mechanism is matched with the water inlet assembly and the water outlet assembly, the pulse
