A self-cleaning foot-operated car wash pump

Abstract

The invention discloses a self-cleaning pedal type car washing pump. The self-cleaning pedal type car washing pump comprises a box body, a pump body and a pedal driving device. The pump body and the pedal driving device are mounted in the box body, the pump body comprises a centrifugal water pump structure composed of a pump shell and centrifugal pump blades, the pedal driving device comprises a pedal, a reset spring, a sector gear, a driven gear, a clutch gear and a driving gear set, the sector gear is engaged with the driven gear, the sector gear is fixedly connected with the pedal, the clutch gear is higher than the driven gear and the driving gear set, the box body is provided with a pin shaft sliding way, the pin shaft sliding way is inclined in the direction perpendicular to the center connecting line of the driven gear and the clutch gear, a rotating shaft of the clutch gear is mounted in the pin shaft sliding way, when the rotating shaft of the clutch gear moves in the pin shaft sliding way, the clutch gear is engaged with the driven gear and the driving gear set, or is disengaged from the driven gear and the driving gear set, and an output rotating shaft of the driving gear set is connected with a rotating shaft of the centrifugal pump blades. According to the pump, electric energy does not need to be consumed for driving a water pump, dual hands are liberated, and operation is convenient.

Description

technical field [0001] The invention relates to a car washing pump, in particular to a self-cleaning pedal car washing pump. Background technique [0002] With the development of the economy and the disappearance of the demographic dividend, the cost of labor has also increased year by year, resulting in higher and higher car washing prices. Many car owners choose to wash their cars by themselves, but the pipeline needs to be connected to the tap water source. It is not realistic for residents living on high floors to connect the pipeline. In the prior art, there is a battery-powered car wash pump, which is powered by the vehicle battery of the car. Generally, the pump is operated from the cigarette lighter. Water can be taken from the nearest river, reservoir, pond and other power sources to wash the car through the water pipe, which is more labor-saving. . However, this kind of water pump needs to lead wires from the inside of the car to the outside of the car, which aff...
