Windshield wiper

Abstract

The invention relates to a car part, particularly to a windshield wiper. The windshield wiper comprises a windshield wiper rod and a windshield wiper blade, wherein the top part of the windshield wiper rod is fixedly connected with the middle part of the windshield wiper blade, a water spraying pipe is fixedly arranged on the outer wall of the windshield wiper rod, and a through cavity penetrating through both ends of the windshield wiper rod is formed in the windshield wiper rod. The windshield wiper also comprises a water taking pipe which is used for supplying water sources for the water spraying pipe and the through cavity, and the water spraying pipe, the through cavity and the water taking pipe are connected by a three-way valve; and an auxiliary water spraying pipe of which both ends are blocked is fixedly arranged on the outer wall of the windshield wiper blade, the middle part of the auxiliary water spraying pipe is fixedly connected with one end, away from a flexible water pipe, of the through cavity by a water pipe, the water pipe is communicated with the inner part of the auxiliary water spraying pipe, and a plurality of through holes are formed in one side, close to the windshield wiper blade, of the auxiliary water spraying pipe . The windshield wiper has the beneficial effect that the use ratio of the water in a water tank of a car is increased.

Description

technical field [0001] The invention relates to an automobile part, in particular to a windshield wiper. Background technique [0002] In areas with frequent sand and dust weather, the windshield of the car is easily covered by sand and dust during the driving process, which affects the driver's driving sight. In order to avoid this from happening, a Several water spray pipes connected to the water tank of the car, and then use the wiper to evenly scrub the windshield, so that the windshield is in a relatively clean state and ensure that the driver's driving line of sight is not disturbed. Comprehensive scrubbing makes this structure have a long distance to spray water from the water spray pipe when spraying water, and the water demand is large. However, the water storage capacity of the automobile water tank is limited, and the water utilization rate needs to be improved. Therefore, a suitable structure is needed to solve the above problems. question. Contents of the inv...
