Filling pipe of washing system

Abstract

The invention provides a filling pipe of a washing system, which belongs to the technical field of auto parts. It solves the problems of short service life and unstable performance of the existing filling pipe. The filling pipe of the washing system includes a pipe body and a liquid injection port arranged at the bottom of the pipe body. The pipe body includes an elastic expansion part and a smooth support part connected with the elastic expansion part. There are several pleats on the elastic expansion part. , the pleated membrane is laid with a deformed thin plate supporting the deformation of the elastic expansion part, a brake button is arranged on the outer end wall of the liquid injection port, and a movable bump linked with the brake button is arranged on the lower side of the liquid injection port. Moving radially inward and outward along the injection port, the upper part of the tube body is provided with an addition port for adding washing liquid. The invention has the advantages of long service life and stable performance.

Description

technical field [0001] The invention belongs to the technical field of auto parts and relates to a filling pipe, in particular to a filling pipe of a washing system. Background technique [0002] The washing system is one of the important components of the car, which can help to clean some impurities on the car windshield. The washing system mainly includes a kettle and a filling pipe. At present, the general steps of adding washing liquid to the car are to open the engine cover first, fix the engine cover with a support rod, then open the filling pipe cover, and inject the washing liquid into the filling pipe mouth. In order to facilitate the addition of washing liquid, designers generally arrange the position of the filling pipe at the edge of the engine compartment of the car. However, due to the complex structure in the engine compartment of the car, in order to avoid key components, the position of the filling port of some models has been changed, which makes it diffic...

AI Technical Summary

Problems solved by technology

However, due to the complex structure in the engine compartment of the car, in order to avoid key components, the position of the filling port of some models has been changed, which makes it difficult to fill the washing liquid, and the washing liquid is often stained on other parts, which is easy to cause some glitches appear

[0003] In response to this situation, many component manufacturers have modified the structure of the filling pipe, using a retractable pipe body to add liquid, avoiding the phenomenon of washing liquid spilling out, but because the filling pipe is often bent and folded , prone to breaking problems, and at the same time, because the filling tube is extended and foldable, it is impossible to fix the two ports of the filling tube at the same time during use, causing the nozzle to slip from time to time
