Description

Technical field:

[0001] The invention relates to an automobile component, in particular to a windshield defroster. Background technology:

[0002] In winter, especially in the morning, the air is oversaturated with moisture due to the low temperature outside the car. The moisture first dissolves and then crystallizes to form frost on the outside of the windshield, which is higher than the outside air temperature. Since the temperature of the car glass surface is radiated by the sky background, it will drop faster and lower than the surrounding objects, so the frost will form faster. When starting the car to travel, it will affect the driver's vision and cause safety hazards. The frost on the windshield is not suitable for glass water or wipers to remove. Generally, cardboard, plastic cards (such as bank cards), or special shovels are needed to manually remove the frost on the windshield, which is inefficient, not clean and thorough, and easy to scratch the surface of the windshield; or start the car and blow warm air to the inside of the windshield to melt the frost on the windshield. The car starts for a long time, consumes a lot of fuel, and the car is seriously damaged. After the frost melts, stains will form on the surface of the windshield, which will affect the driver's vision and cause safety hazards. Summary of the invention:

[0003] The purpose of the present invention is to provide a windshield defroster which can remove frost on the surface of a windshield conveniently and quickly without damaging the surface of the windshield.

[0005] Grooves are arranged on the bottom surfaces of the steel wire fastening end and the adjusting and tightening end, and the metal wire is placed in the grooves.

[0006] Chamfers are formed on both sides of the bottom surfaces of the steel wire fastening end and the adjusting and tightening end.
