When the two groups of scraping plates correspond to the two groups of filter cloths respectively, by using the threaded cooperation of the two groups of connecting screws and the four groups of connecting nuts, the operator rotates the four groups of connecting nuts clockwise and counterclockwise by hand. When the four groups of connecting nuts are in close contact with the two groups of connecting plates respectively, the use positions of the two groups of scraping plates are fixed. Then, by using an external control panel, the forward and reverse motor works. The output end of the forward and reverse motor can drive the installation shaft to rotate. The rotating installation shaft can drive the two groups of rotating tubes to rotate through the two groups of main belt pulleys, the two groups of driven belt pulleys and the two groups of transmission belts. The two groups of rotating tubes can drive the two groups of filter cloths to rotate respectively. During the rotation of the two groups of filter cloths, the two groups of scraping plates can scrape the impurities adsorbed on the surfaces of the two groups of filter cloths. External air can enter the interior of the lamp housing through the two groups of filter cloths and the two groups of rotating tubes. By setting the rotating tube, a cleaning structure is provided, which can remove the impurities attached to the surface of the filter cloth structure, and provides a guarantee for the continuous use of the automobile headlamp with a defrosting function.

[0037] Working principle:
[0038] When actually using the automotive headlamp with a defrosting function, the operator moves the lamp housing 1 by hand. When the two groups of metal posts 22 are electrically connected to the automotive power supply, screws are used to complete the connection between multiple groups of mounting plates 10 and the vehicle. By using an external control panel, the drive motor 15, the main LED lamp beads 8, and multiple groups of auxiliary LED lamp beads 9 can be made to work. The heat generated by the circuit board 5, the main LED lamp beads 8, and multiple groups of auxiliary LED lamp beads 9 can be transferred to the heat dissipation fins 6 by using the principle of heat transfer. When the drive motor 15 works, it can drive the first bevel gear 16 to rotate. Since the first bevel gear 16 meshes with multiple groups of second bevel gears 20, the rotating first bevel gear 16 can push multiple groups of second bevel gears 20 to rotate. The rotating multiple groups of second bevel gears 20 can drive multiple groups of fan blades 21 to rotate through multiple groups of transmission shafts 19. The rotating fan blades 21 can draw the hot air inside the lamp housing 1 into the interiors of multiple groups of air ducts 11 through multiple groups of air guide funnels 17. Finally, the hot air is ejected from the upper openings of multiple groups of air ducts 11. The ejected hot air contacts multiple groups of lamp covers 7, and can melt the cold frost attached to the surfaces of multiple groups of lamp covers 7. Multiple groups of filter plates 18 and multiple groups of waterproof breathable membranes can prevent dust from entering the interiors of multiple groups of air ducts 11. By providing the mounting box 4, it is convenient to remove the cold frost attached to the surface of the lamp covers 7, improving the usability of the automotive headlamp with a defrosting function. At the same time, according to the above operations, after the lamp housing 1 is installed, the use heights of the two groups of scraping plates 14 can be adjusted by hand. When the two groups of scraping plates 14 respectively correspond to the two groups of filter cloths 13, by using the threaded cooperation of the two groups of connecting screws 24 and the four groups of connecting nuts 25, the operator rotates the four groups of connecting nuts 25 clockwise and counterclockwise by hand. When the four groups of connecting nuts 25 are respectively in close contact with the two groups of connecting plates 23, the use positions of the two groups of scraping plates 14 are fixed. Then, by using an external control panel, the forward and reverse motor is made to work. The output end of the forward and reverse motor can drive the mounting shaft 27 to rotate. The rotating mounting shaft 27 can make the two groups of rotating tubes 12 rotate through the two groups of main belt pulleys 28, the two groups of driven belt pulleys 29, and the two groups of transmission belts 30. The rotating two groups of rotating tubes 12 can respectively drive the two groups of filter cloths 13 to rotate. During the rotation of the two groups of filter cloths 13, the two groups of scraping plates 14 can scrape off the impurities adsorbed on the surfaces of the two groups of filter cloths 13. External air can enter the interior of the lamp housing 1 through the two groups of filter cloths 13 and the two groups of rotating tubes 12. By providing the rotating tubes 12, a cleaning structure is provided, which can remove the impurities attached to the surface of the filter cloth structure, ensuring the continuous use of the automotive headlamp with a defrosting function.
