[0030] Further, when using the device, when driving in rainy days, after driving for a period of time, when it is necessary to defog the rearview mirror, the button inside the car is activated, and the rotation of the output shaft of the first motor 6 drives the driving gear 7 to rotate through the power supply, and the rotation of the driving gear 7 drives the driven gear 8 to rotate, and the rotation of the driven gear 8 drives the rotating rod 9 to rotate, and the rotation of the rotating rod 9 drives the fan-shaped water spray nozzle 17 to rotate 110 degrees, and the maximum angle is 120 degrees. However, in order to avoid fitting the structure of the rearview mirror housing 2, the maximum angle can be 110 degrees, so that the fan-shaped water spray nozzle 17 Water can be sprayed to the farthest end of the mirror 4. At this time, the electronic valve 16 is started and opened by the power supply. The electronic valve 16 flows the anti-fog liquid in the water tank 15 through the water pipe to the inside of the fan-shaped water nozzle 17 to spray the de-fogging liquid.

At the same time, some dehumidifying liquids are of poor quality and will produce some foam, which can be solved by the scraper 13. The rubber block cleans up the excess liquid, and the sponge block absorbs the foam to avoid being blocked by the dehumidifying liquid sprayed by the fan-shaped water nozzle 17, thereby increasing the novelty.
[0032] Furthermore, when using the device, when encountering heavy rain, activate the button in the car to start the second motor 20. The output end of the second motor 20 rotates to drive the gear 21 to rotate. The rotation of the gear 21 drives the rack 19 to slide. The sliding displacement of the rack 19 drives the water baffle 22 to slide. The sliding displacement of the water baffle 22 is further away from the interior of the rearview mirror housing 2, so that the extension distance of the water baffle 22 is increased to 2-5cm compared to the traditional 1cm, which can block rainwater over a larger area, enhance the rearview mirror's ability to prevent water from blurring the mirror 4, and has safety performance.
[0033] The combination of the device's three innovative features helps existing electrically heated rearview mirrors to be more effective in removing mist and preventing rain.
[0034] A method for manufacturing a defogging automobile rearview mirror: Step 1: First, drill threaded holes in the fixing bracket 1 to facilitate later installation on the car bracket. Next, the rearview mirror housing 2 is integrally formed through an injection mold, and holes are drilled inside the rearview mirror housing 2 to allow the power cord to flow out. The base of the mirror mounting block 3 is then fixed with screws, and then the first motor 6 and the second motor 20 are installed. The power cords of the two motors are pulled out of the holes, and after they are fixed, gears and other components are installed.
[0035] Step 2: After the gears are installed, install the mirror 4 onto the mirror mounting block 3, fix the second bevel gear 11 to the threaded rod, and then thread the scraper 13 onto the threaded rod 12.
