One-way check valve and windshield washing system

Abstract

The invention provides a one-way check valve and a car windshield washing system, and relates to the technical field of car accessories. The one-way check valve comprises a first valve body, a secondvalve body and an elastic valve element, wherein the first valve body and the second valve body are connected to each other, and the elastic valve element is arranged between the first valve body andthe second valve body; the elastic valve element is arranged on the output end of the first valve body and is capable of opening or closing the output end of the first valve body; when the output endof the first valve body is opened by the elastic valve element, media in the first valve body can flow into the second valve body; and when the output end of the first valve body is closed by the elastic valve element, media in the second valve body can be prevented from flowing back to the first valve body. The car windshield washing system comprises the one-way check valve. According to the one-way check valve and the car windshield washing system, the problems of multiple components, complex manufacturing and assembly processes and high production cost of the one-way check valve in the prior art and high performance requirements on a return spring in the existing one-way check valve are solved.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a one-way check valve and an automobile windshield washing system. Background technique [0002] The function of the one-way check valve is to limit the flow direction of the medium in the pipeline and prevent the medium from flowing backward. At present, the structure of the existing typical one-way check valve is as follows: figure 1 As shown, a spring is usually used in the valve to act on the spool, and the opening and closing of the valve is controlled by the movement of the spool. [0003] Depend on figure 1 It can be seen that the above-mentioned valve has many components, many manufacturing and assembly processes, and high production cost; the above-mentioned one-way check valve needs to have a good contact and sealing fit between the valve core and the valve body in order to play a good role. The sealing and non-return function of the valve has higher requirements ...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a one-way check valve and an automobile windshield washing system, so as to alleviate the problems of the existing one-way check valve with many components, complicated manufacturing and assembly process, high production cost and the existing one-way check valve. In the check valve, the performance requirements of the return spring are relatively high, etc.
