The 4 raindrops on the windshield wiper are used to adjust the speed of the wiper blade. Related introduction about windshield wipers: 1. Introduction to windshield wipers: Wipers, also known as windshield wipers or windscreen wipers, are devices used to wipe away raindrops and dust attached to the vehicle's windshield to improve the driver's visibility and enhance driving safety. Due to legal requirements, almost all vehicles are equipped with wipers. 2. Operating principle of windshield wipers: The power source of the wiper comes from the motor, which is the core of the entire wiper system. The quality requirements for the wiper motor are quite high. It uses a DC permanent magnet motor, and the wiper motor installed on the front windshield is generally integrated with the worm gear mechanical part.
After years of driving, I discovered that the four small water droplet icons on the wiper actually represent the windshield washer button. Every time the windshield gets dusty, covered with bugs, or blurred by rain, pressing it sprays cleaning fluid which works with the wiper action to automatically clean the glass. This tool is super practical during long-distance drives or urban commutes, as maintaining clear visibility is key to preventing accidents. I recommend choosing high-quality cleaning fluid and regularly checking the fluid level to avoid nozzle clogging; use antifreeze type in winter to prevent freezing. Making it a habit to use it can enhance driving safety, and don’t forget it operates more efficiently in heavy rain or foggy conditions. After all, timely cleaning when visibility is poor is more important than anything—don’t wait for small issues to become major hazards.
