Abstract

The invention relates to a pedal type water pump which is characterized by comprising a pedal pressing plate, wherein the tail end of the pedal pressing plate is connected with a piston; the piston is positioned in a water pumping cylinder and tightly abutted with the inner wall of the water pumping cylinder; the other side of the piston is connected with a compression spring; a water inlet and a water outlet are respectively arranged on the water pumping cylinder; an inward one-way valve is arranged on the water inlet; an outward one-way valve is arranged on the water outlet; and a water inlet pipe and a water outlet pipe are respectively connected with the outside of the water inlet and the water outlet. When the pedal pressing plate of the pedal type water pump of the invention is stepped down, water in the water pumping cylinder can be pressed out, and the piston is ejected by the elasticity of the compression spring and the water can be pumped when the feet are moved away. Also, the pedal pressing plate can be pulled to improve the water pumping rate. The invention has simple use, can be used in places without a power supply, saves electricity and energy, and is suitable for outdoor use.

Description

Technical field:

[0001] The invention relates to a water pump, in particular to a foot-operated water pump, and belongs to the technical field of water pumping appliances. Background technique:

[0002] The water pump is also known as the "water pump". Centrifugal pumps are hydraulic machines that use atmospheric pressure to lift water from low to high. It consists of water pump, power machinery and transmission device. It is widely used in farmland irrigation and drainage, as well as water supply and drainage in industrial and mining enterprises and cities and towns. In order to meet different needs, there are many types.

[0003] Common pumps are piston, centrifugal and axial flow. Piston pumps use atmospheric pressure, such as common water presses. The centrifugal pump uses the rotation of the impeller to drive the water to obtain centrifugal force, and the water is lifted to a high place, but the height of the suction port of the centrifugal pump is still restricted...
