What is the symbol for adding water to the wiper?

[SanCorbin]

The symbol for adding water to the wiper is a fan shape with an umbrella in the middle. Here is an introduction to the wiper: 1. Introduction: It is a blade structure installed in front of the windshield. 2. Components: It consists of a motor, reducer, four-bar linkage, wiper arm spindle, wiper blade assembly, etc. 3. Function: Its main purpose is to remove rain, snow, and dust that obstruct the view on the windshield. 4. Principle: It uses a DC permanent magnet motor. The wiper motor installed on the front windshield is generally integrated with the worm gear mechanical part. The worm gear mechanism serves to reduce speed and increase torque, and its output shaft drives the four-bar linkage, converting continuous rotary motion into a left-right swinging motion through the four-bar linkage.
