Vehicle headlight cleaning apparatus

Abstract

The invention relates to a vehicle headlamp cleaner which is characterized in that a liquid-filling working cylinder takes a cylindrical shape; the liquid-filling working cylinder is internally provided with a check valve which is matched with an internal plane of the liquid-filling working cylinder; two ends of a tensile spring are respectively fixed on the valve core hoisting lug of the check valve and a spring fixed base; two ends of a compression spring are respectively fixed at the end of the liquid-filling working cylinder and the end of a shell. When cleaning liquid enters the interiorof the cleaning liquid through a cleaning liquid inlet of a base, the pressure of the cleaning liquid overcomes the elasticity of the compressing spring to push the liquid-filling working cylinder, the check valve and a nozzle to motion together; when the liquid-filling cylinder motions to the limit position, the liquid-filling working cylinder stops motioning, when the valve core is opened underthe pressure of the cleaning liquid, a complete working circuit of the cleaner is formed. When the cleaning operation is completed, as the pressure of the cleaning liquid disappears, under the co-action of the tensile spring and the compression spring, the valve core is closed, the liquid-filling working cylinder contracts back into the shell till the initial position is recovered and the whole cleaning process is completed. The vehicle headlamp cleaner has the advantages of reliable working structure and high cleaning efficiency.

Description

technical field [0001] The invention relates to a matching device for vehicle lights, in particular, the invention relates to a cleaning device for vehicle headlights. The vehicle headlight cleaning device of the present invention is especially suitable for cleaning the headlights of gas discharge lamps. Background technique [0002] As gas discharge lamps are widely used in my country's car market, the requirements for the safety of lamp lighting are becoming more and more strict and standardized. For this reason, many vehicles are equipped with headlamp cleaning devices. In particular, since headlights such as gas discharge lamps are more likely to dazzle the other driver and cause danger due to the pollution of the lights during vehicle driving, at present, cleaning equipment is provided for the headlights of gas discharge lamps. has become mainstream. [0003] So far, many related technologies have been developed. For example, Japanese Patent Publication No. "JP200328...

AI Technical Summary

Problems solved by technology

In addition, a booster (spring) device is installed at the nozzle and the fixed piston part respectively, and the nozzle can be slidably inserted into one end of the fixed piston part, just because the invention of the headlight cleaning device is to prevent rainwater from intruding into it. etc., the invention of the headlight cleaning device focuses on the connection and matching between its internal and external components and the external car body. Therefore, obviously, the structure of the cleaning device in this reference document is relatively complicated, resulting in troublesome

[0007] In addition, the fixed piston part of the headlamp cleaning device disclosed in the reference document is in a fixed state, and a small force (spring) member is respectively arranged on the fixed piston part and the nozzle part, and by virtue of the elastic force of the two small springs, respectively Apply force to the piston part and the nozzle part, so that the nozzle part only slides relative to the piston part, causing the nozzle part to be subjected to a relatively large load. Long-term use will affect the use efficiency of the nozzle part, thereby causing the entire cleaning device to fail. Cleaning efficiency is affected
