The water pump is a reciprocating water pump, and a piston mechanism of the piston rod is provided with a pair of piston rods for reciprocating pressing. The rotating shaft of the cam mechanism is connected to the motor output shaft through a speed reduction mechanism.

The casing forms a sliding slot around the piston rod through a surrounding wall. The sliding slot is provided with a slider abutting against the end of the piston rod. The cam circumferential surface of the cam mechanism abuts against the sliding block.

The speed reduction mechanism includes a worm fixed to the output shaft of the motor, a worm wheel meshed with the worm, a primary gear coaxially fixed to the worm wheel, and a secondary meshing with the primary gear and fixed to a rotational axis of the cam mechanism gear.

The handle portion is provided with a button for controlling the start and stop of the motor.

Beneficial effect

As can be seen from the above description of the present invention, the advantages of the present invention over the prior art are: Since the motor is used to drive the pump action, it is no longer necessary to manually press the piston rod of the water pump, and the pump can be operated only by starting the motor, so that the operation is convenient and labor-saving; the motor driven pump is used, as long as the motor is not turned off, The water pump is continuously operated, and the steam discharged is also more continuous, powerful and uniform; the utility model can be conveniently applied to the original steam mop without major improvement on the existing steam mop, only on the basis of the original steam mop Adding the motor and cam mechanism can achieve better results with less cost.
