The invention discloses a spray head for a vehicle wiper, and aims to solve the problem that the spray head is mounted on the wiper to be used and realize the technology that the spray head swings along with a wiper blade, and complex stains on windshield glass are not thoroughly cleaned in a short-distance spraying manner. The spray head comprises a main body and a nozzle, a plurality of area channels allowing fluid to pass through are arranged in the main body, the diameters of the area channels are gradually reduced in the flowing direction of the fluid, the area channels are communicated to form a jet flow channel, and the jet flow channel is provided with an input end allowing the fluid to pass through and a fluid output end. The diameter of the output end is smaller than that of the input end. According to the relation of the position, the distance, the motion trail and the like of the windshield wiper and windshield glass, the ultra-small spray head suitable for being installed on the windshield wiper is designed, and the technical parameters of the spray liquid shape, the spray angle, the sector angle, the installation position, the spray flow, the water outlet pressure and the like of the spray head are suitable for being installed on the windshield wiper for use; the windshield wiper can thoroughly clean complex stains on the windshield glass.
本发明公开一种用于车辆雨刷器上的喷头,为解决安装在雨刷器上使用喷头的问题,实现喷头随着雨刷片摆动,近距离喷射清洗风挡玻璃复杂污渍不彻底的技术。该喷头包括主体和喷嘴,主体内部具有多个供流体通过的区域通道,多个区域通道的直径沿着流体的流动方向逐渐减小,多个区域通道连通形成一个射流通道,射流通道具有供流体通过的输入端和流体的输出端,输出端的直径小于输入端的直径。本发明根据雨刷器与风挡玻璃的位置、距离、运动轨迹等关系,设计了适合安装在雨刷器上的超小喷头,喷头的喷射液体形状、喷射角度、扇面角度、安装位置、喷射流量、出水压力等技术参数适合安装在雨刷器上使用,使得雨刷器能彻底清洗风挡玻璃复杂污渍。
