Two-edge internal-washing wiper

Abstract

This invention discloses a double-knife rain wiper spraying glass cleaning solution onto the windshield directly by a double-knife rubber strip composed of a rubber strip, a bracket, a rocker and a solution guiding tube characterizing that a cleaning groove is set at the bottom of the strip and the guiding tube connected with the strip sprays the cleaning solution onto the windshield directly so as to increase the efficiency of the rain wiper.

Description

technical field [0001] The invention relates to a windshield wiper for motor vehicles, boats and airplanes, in particular to a double-edged inner wash type wiper, which is used for scraping rain and snow and cleaning windshields on motor vehicles, boats and airplanes. Background technique [0002] In rainy and snowy weather, in order to ensure good transparency of the windshield, current wipers use rubber strips to swing on the windshield according to a certain arc through mechanical structures such as rocker arms to scrape off rain and snow water in time. The dirt on the windshield is sprayed by the wiper with the glass washer fluid spraying structure, and the glass washer fluid is sprayed on the windshield to scrape off the dirt. When the wiper is working, the edge of the rubber strip is in close contact with the windshield, forming a scraping angle, which directly affects the scraping effect. The angle for the best scraping effect should be along the direction of the swi...

AI Technical Summary

Problems solved by technology

In actual work, due to the softness of the rubber edge, when the wiper is swinging, the frictional resistance between it and the windshield makes it twist and vibrate, which may easily cause the front angle to be smaller than the rear angle or one-sided tilting

Under normal circumstances, the twisting back and forth also caused rapid damage to the rubber edge

And the cleaning fluid sprayed by the spray structure is not easy to be sprayed on the windshield evenly and effectively
