[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0034] See also Figure 1-2A defogger headlight comprises an external frame 1, wherein the external frame 1 comprises: a defogger frame 11, wherein a lamp body 12 is arranged inside the defogger frame 11, wherein the rear side wall of the defogger frame 11 is connected to the mirror surface through a bracket 13, wherein a defogger assembly 2 is arranged inside the defogger frame 11, wherein the defogger assembly 2 comprises: a screw rod 21, which penetrates and is rotatably connected inside the defogger frame 11, wherein the outer surface of the part of the screw rod 21 on the right side of the defogger frame 11 is smooth and has no threads, a volute spring 22, which is sleeved on the outside of the smooth part on the right side of the screw rod 21, wherein a dustproof frame is arranged outside the volute spring 22, a pull rope 23, which is fixedly connected to the tail end of the volute spring 22, a scraper 24, wherein the upper part of the scraper 24 is threadedly connected to the screw rod 21 through a threaded block, a slide 25, which is arranged inside the defogger frame 11 and is located below the lamp body 12, wherein the lower part of the scraper 24 is slidably connected to the slide 25 through a slider. The scraper 24 is of arc design. A water collecting plate 26 is provided at the front side of the demisting frame 11, and the water collecting plate 26 is located below the scraper 24, and the water collecting plate 26 is an inclined surface, and a water collecting frame 27 is provided on the right side of the water collecting plate 26. The sliding connection between the lower part of the scraper 24 and the chute 25 is designed by a dovetail groove.

[0035] The user installs the device above the mirror through the bracket 13. When water mist is formed on the surface of the lamp body 12 due to the influence of water vapor, the defogger assembly 2 is activated to defog it: the user pulls the pull rope 23 downwards, and the pull rope 23 stretches the spiral spring 22 fixedly connected above it. Since the spiral spring 22 is fixedly connected to the screw rod 21, when the spiral spring 22 is stretched by the pull rope 23, the screw rod 21 rotates, and the scraper 24 threadedly connected to the screw rod 21 scrapes the water mist on the surface of the lamp body 12 from left to right. When the scraper 24 moves to the rightmost position, the pull rope 23 is released, and the spiral spring 22 is driven by the torque force to reverse the screw rod 21, thereby driving the scraper 24 back to the left side without affecting the next use. The arc-shaped scraper 24 fits the surface of the lamp body 12 more closely, so that the scraper 24 can scrape off the water mist more thoroughly. The water mist is gathered into water droplets when being scraped off from left to right by the scraper 24, and then drops onto the water collecting plate 26 below. Then, it slides into the water collecting frame 27 through the inclined water collecting plate 26, so as to prevent the gathered water droplets from falling elsewhere and causing additional cleaning requirements for the user. The lower part of the scraper 24 slides in the lower chute 25, which plays an auxiliary sliding role. At the same time, the dovetail groove design is adopted at the connection to prevent the lower part of the scraper 24 from deviating from the original track when sliding on the chute 25, thereby affecting the demisting effect.

The fan 32 and the heating wire 33 are provided at three locations, and the length of the heating frame 31 is equivalent to the length of the lamp body 12.

[0038] When there is less water mist on the surface of the lamp body 12 by the heating component 3 and after the scraper 24 of the demisting component 2 scrapes off the water mist, the surface of the lamp body 12 is heated and air-dried: the fan 32 is turned on, and the wind blown out by the fan 32 is heated after passing through the heating wire 33, and blown out through the through hole on the front side of the heating frame 31. The inclined baffle 34 guides the hot air to the surface of the lamp body 12, and the surface of the lamp body 12 is heated and air-dried, so that the effect of removing water mist is better. The fan 32 and the heating wire 33 are both set at three places, so that the efficiency of air drying and heating is higher, and the demisting efficiency is improved. The length of the heating frame 31 is equivalent to that of the lamp body 12, so that every part of the lamp body 12 can be air-dried by hot air, and the overall demisting effect of the surface of the lamp body 12 is better.
