The car rearview mirror reflects the situation behind, to the sides and below the car, allowing the driver to indirectly see the situation in these positions. It acts as a "second eye" and expands the driver's field of view.

[0003] Most of the existing car rearview mirrors will use the anti-fog function when used on rainy days. The defogger effect of the rearview mirror is achieved by heating the rearview mirror and exhausting the air through the exhaust holes. Since the existing defogger device has poor waterproof effect, rainwater may enter the rearview mirror through the exhaust holes, causing rust inside the rearview mirror and affecting the heating function.

[0026] 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 them. 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.

[0027] See also Figure 1-5 As shown, the utility model is a fog-proof automobile rearview mirror, a rearview mirror housing 1, a lens frame 11 is connected to the front of the rearview mirror housing 1, a rearview lens 12 is connected to the inner wall of the lens frame 11, a stopper 34 is slidably connected to the inner wall of the lens frame 11, a connecting rod 33 is connected to the back of the stopper 34, a fixing plate 32 is connected to the bottom of the connecting rod 33, a connecting plate 31 is connected to the front of the fixing plate 32, and an electric push rod 3 is connected to the front of the connecting plate 31. The back of the heating box 2 is connected to the front of the electric push rod 3, so that the electric push rod 3 can stably push the stopper 34, and it is also more convenient for the temperature sensor 22 to control it.

[0028] An air blowing device 26 is connected to the bottom of the inner wall of the rearview mirror housing 1. By setting a block 34, if it rains when the car is stopped, rainwater will be blocked by the block 34 to make it difficult for it to enter the exhaust hole, thereby reducing the amount of rainwater entering the rearview mirror housing 1. By reducing the entry of rainwater, it is not easy to rust. The rainwater is discharged through the air blowing device 26 and the drainage hole 14. The rearview mirror housing 1 will not rust due to long-term accumulation of rainwater, and there will be no problem of excessive rainwater affecting the circuit of the heating function.

[0029] A connecting handle 13 is connected to the left side of the rearview mirror housing 1, and a heating box 2 is connected to the back of the rearview lens 12. By setting the heating box 2, specifically by starting the heating tube 21 to heat the lens in the heating box 2 to increase the surface temperature of the lens, the effect of removing water mist and rainwater is achieved, so that it will not affect the effect of observing the rear of the car while driving, and the road conditions can be better understood, making driving safer and protecting the driver and passengers. A heating tube 21 is connected to the bottom of the inner wall of the heating box 2, and an air pipe 24 is connected to the left and right sides of the heating box 2. The front side of the air pipe 24 is connected to the back side of the lens frame 11. By connecting the front side of the air pipe 24 to the back side of the lens frame 11, the hot air can be accurately discharged from the heating box 2 through the air pipe 24 and then through the exhaust hole of the lens frame 11. The lens is heated by the heating tube 21 to achieve the effect of removing water mist, so that the water mist will not adhere to the rearview lens 12, and will not affect the driver's observation of the rearview lens 12, so as to better observe the road conditions.

[0030] By setting up an air pipe 24, the hot air in the heating box 2 can be discharged, and the temperature in the heating box 2 will not be too high to affect the service life of the rearview lens 12, and the heating circuit will not be affected due to the excessive temperature. The top and bottom of the inner wall of the heating box 2 are connected to temperature sensors 22, and the left and right sides of the inner wall of the heating box 2 are provided with fans 23. The inner wall of the air pipe 24 is in contact with the outer surface of the fan 23, and the inner wall of the lens frame 11 is provided with an exhaust hole. The inner wall of the air pipe 24 is in contact with the outer surface of the fan 23, so that the hot air sucked by the fan 23 can be stably transmitted through the air pipe 24, thereby cooling the heating box 2, and the gas can be discharged by opening the exhaust hole.

[0031] Among them, the brand of the temperature sensor 22 may be Huahong, the model may be IS-PR500RTU, and the material may be stainless steel. The temperature sensor 22 controls the electric push rod 3 to control the extension and retraction of the block 34 to control the exposure of the exhaust hole to control the temperature in the heating box 2. The exhaust time will not be too long, causing the temperature to be too low to affect the defog effect, and the temperature will not be too high to affect the service life of the rearview lens 12. By setting the fan 23, the hot air from the heating box 2 can be quickly discharged to reduce its temperature, and the hot air in the heating box 2 can also flow more evenly, making the heating effect more stable, and the rearview lens 12 can be defogged evenly.

[0032] The bottom of the air supply pipe 1 24 is connected to the air supply pipe 25, the back of the air supply pipe 25 is connected to the front of the blowing device 26, and the back of the heating box 2 is connected to the front of the electric push rod 3. The air flow is transported to the blowing device 26 through the air supply pipe 25, and the gas is transported for a second time through the air supply pipe 25 to produce other uses. There is no need to add a new blowing device, which saves space and reduces costs. The rainwater in the rearview mirror housing 1 is blown out through the drainage hole 14 through the blowing device 26. The bottom of the lens frame 11 is provided with a drainage hole 14. After the rainwater enters the rearview mirror housing 1 through the drainage hole 14, it can flow out through the drainage hole 14 so that it will not remain in the rearview mirror housing 1.

[0033] A specific application of this embodiment is:

[0034] When in use, the rearview mirror housing 1 is installed on the car through the connecting handle 13. When water mist and rainwater adhere to the rearview lens 12, the surface temperature of the lens is increased by starting the heating tube 21 to heat in the heating box 2, so as to achieve the effect of removing the water mist and rainwater, so that it will not affect the effect of observing the rear of the car while driving. Then, the temperature in the heating box 2 is sensed by the temperature sensor 22. When the temperature is too high, the temperature sensor 22 will send a signal to make the electric push rod 3 push the fixing plate 32 to move the block 34 backward to expose the exhaust hole, and the hot air in the heating box 2 is sucked out by the fan 23, and finally discharged from the exhaust hole through the air pipe 24, so as to control the temperature in the heating box 2 to be controlled within a fixed range. The rearview mirror housing 1 is designed to have a good defogging effect. If the vehicle is driving on a rainy day, rainwater may enter the rearview mirror housing 1. Part of the rainwater will be discharged through the drainage hole 14. The remaining rainwater will be blown into the drainage hole 14 by the air blowing device 26 when the gas is delivered through the air delivery pipe 1 24. The rainwater will be discharged through the drainage hole 14. If it rains when the vehicle is stopped, the rainwater will be blocked by the block 34, making it difficult for the rainwater to enter the exhaust hole. Thus, very little rainwater will enter the rearview mirror housing 1. The rainwater that enters the rearview mirror housing 1 will be discharged through the air blowing device 26 and the drainage hole 14 when the rearview lens 12 is defogging. The rearview mirror housing 1 will not rust due to long-term accumulation of rainwater, which will affect the heating device.
