Description

Technical Field

[0001] The invention relates to the field of automobile windshield cleaning, in particular to an automobile windshield high-pressure airflow cleaning system. Background Art

[0002] When a car is driving and encounters rainy weather, in order to prevent the rain from affecting the driver's vision, it is necessary to clean and scrape the rain on the outer surface of the windshield. The traditional car wiper system mainly uses a mechanical arm and a rubber scraper to remove the rain on the windshield. This system has relatively mature technology in design and use, and can effectively clean the windshield in most cases. However, this system also has some obvious defects:

[0003] 1. Cleaning efficiency issue: In heavy rain, snow or extreme weather conditions, the cleaning efficiency of traditional wipers may be insufficient, resulting in obstruction of the driver's vision and affecting driving safety.

[0004] 2. Wear and maintenance: The rubber blades of the wipers will gradually wear out during use and need to be replaced and maintained regularly, otherwise the cleaning effect will be reduced.

[0005] 3. Noise problem: The wiper will produce certain noise when working, especially when driving at high speed, the noise will be more obvious, affecting the driving experience.

[0006] 4. Aerodynamic impact: The wiper arm will have a certain impact on the aerodynamic characteristics of the vehicle when driving at high speed, increasing wind resistance and fuel consumption;
