Dispensing device, dispensing assembly, and washing device having the same

Abstract

A dispensing device includes a dispensing pump, a drive assembly, and a one-way transmission mechanism. The dispensing pump includes a pump housing having a liquid inlet and a liquid outlet, and a pump body. The drive assembly includes a driver movable between a first position and a second position. The one-way transmission mechanism is located between the drive assembly and the pump body. During movement of the driver from the first position to the second position, the drive assembly drives the one-way transmission mechanism to move, and the one-way transmission mechanism drives the pump body to move, to suck detergent through the liquid inlet and discharge the detergent through the liquid outlet. During movement of the driver from the second position to the first position, the drive assembly drives the one-way transmission mechanism to move, and the one-way transmission mechanism does not drive the pump body to move.
