Car headlight automatic demist device

Abstract

The invention provides a car headlight automatic demist device. The car headlight automatic demist device includes a light cover, a demist module and a ventilation module; an air inlet and an air outlet are formed in the upper end of the light cover, and a drainage hole is formed in the lower end of the light cover; the demist module includes a demist net; the demist net includes a detecting module, the detecting module includes a power source and a detecting wire; a drainage tank is arranged at the bottom of the demist net, and a one-way valve is mounted in the drainage hole; and the ventilation module includes an air inlet pipeline and an air outlet pipeline; and electromagnetic valves are correspondingly arranged in the air inlet pipeline and the air outlet pipeline. According to the car headlight automatic demist device, when water mist exists in car headlights, automatic detecting is turned on, thus the water mist in the car headlights can be absorbed by the demist module, thus the water mist quickly forms water drops to be drained out, meanwhile the ventilation module can also accelerate heat dissipation of the car headlights, the temperature difference is quickly eliminated,and the water mist is prevented from forming again.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to an auto headlight defogging device. Background technique [0002] Car headlights, also known as car headlights, are devices that provide drivers with good lighting at night or in areas with weak lighting environments; usually, car headlights are equipped with ventilated rubber tubes on the rear cover for Discharge the heat generated when the headlight is turned on, maintain the normal working temperature of the headlight, and ensure the stability of the use of the headlight; therefore, the moisture in the air will also enter the inside of the headlight lampshade through the ventilating rubber tube, and with the accumulation of water vapor, at the same time With the temperature difference between the inside and outside of the car headlight, water mist will be adsorbed on the inner surface of the car headlight lampshade; the water mist will not only affect the lighting effect of the headl...

[0002] Car headlights, also known as car headlights, are devices that provide drivers with good lighting at night or in areas with weak lighting environments; usually, car headlights are equipped with ventilated rubber tubes on the rear cover for Discharge the heat generated when the headlight is turned on, maintain the normal working temperature of the headlight, and ensure the stability of the use of the headlight; therefore, the moisture in the air will also enter the inside of the headlight lampshade through the ventilating rubber tube, and with the accumulation of water vapor, at the same time With the temperature difference between the inside and outside of the car headlight, water mist will be adsorbed on the inner surface of the car headlight lampshade; the water mist will not only affect the lighting effect of the headlight, but also have the risk of damaging the electrical circuit of the headlight; After a period of time, the fog will be discharged out of the lamp through the ventilation pipe along with the hot air. If it cannot be discharged in time, the headlights of the car need to be repaired or replaced. Such an operation is not only time-consuming and labor-intensive, but also not conducive to saving the use cost of the car; In addition, when the seal of the car headlight lampshade is damaged, rainwater will enter the interior of the car headlight to form water accumulation, which will also cause damage to the electrical circuit of the car headlight, and the existing car headlight device cannot solve this problem. approach to the problem; in summary, there are therefore flaws
