Problems solved by technology

However, due to the limitation of the installation position and number of the nozzle body, it is impossible to effectively spray and lubricate the wiper area evenly. On the one hand, the water on the front window is insufficient and the wiper is dry. Not only is it difficult to achieve good results, but it is also easy to damage Wipers; on the other hand, too much water is sprayed locally, and the wiper will jump during the wiping process, and water marks and linear residues will easily appear after wiping

Abstract

The invention relates to a wetting type water spray windscreen wiper. A windscreen wiper buckle of the windscreen wiper is installed on flow deflectors and used for being connected with a windscreen wiper support. A flow guide channel is formed in each flow deflector. A plurality of spray head bodies are pre-embedded in two sides of each flow guide channel. A circular arc-shaped opening groove is formed in one side, close to a windscreen, of each spray head body and extends along the direction of the flow deflectors. Two flow guide pipes are expanded by a water pipe through a reducer tee connector and are respectively communicated with the flow guide channels in the flow deflectors on two sides of the windscreen wiper buckle through pre-embedded connecting pieces of the flow deflectors. The wetting type water spray windscreen wiper can ensure that rubber windscreen wiper strips are provided with sufficient moisture when scrapping the windscreen and can be well attached to the surface of the windscreen, and therefore frictional resistance between the windscreen wiper strips and the windscreen is reduced, frictional noise is lowered, motor load is reduced, water waves and linear residue can not be generated, and the windscreen is clean.

Description

technical field [0001] The invention belongs to the technical field of automobile accessories, and relates to a wiper, in particular to a wetting type water spray wiper. Background technique [0002] When the car is driving on the road, the windshield is easy to stick to dust, and it is necessary to use a wiper to wipe off the dust accumulated on the front window. The key to the good function of the wiper is: the rubber wiper strip can maintain sufficient humidity. Only with sufficient humidity can the rubber wiper strip have very good toughness to maintain tight contact with the window glass. At present, the device for cleaning the windshield on the automobile mainly consists of a washing system and a wiper system. The nozzle body is installed on the outer panel of the engine hood or the decorative panel, and the washing water in the water storage tank is delivered to the nozzle body through the water pump, and the washing water is divided into fine jets and sprayed to th...
