Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of headlight drying, and specifically relates to an efficient heat circulation drying device for headlights. Background Art
[0002] Automobile lamps are prone to fogging, and the fog mainly concentrates on the lower part or side of the lamp. As Figure 1 shown, it is the so-called "cold zone", which is likely to cause consumer complaints. Regarding the fog in headlights, the current conventional solutions mainly include the following: First, anti-fog coating: By means of a hydrophobic coating, the inner surface of the lamp cover is made hydrophobic, so that water vapor forms an extremely thin water film on the inner surface of the lamp cover to prevent fogging. The disadvantage is that it will form runs after long-term use or when the spraying method is improper; Second, desiccant: Magnesium chloride desiccant is often used for headlight desiccants, which has a relatively high moisture absorption rate, but has the limitations of irreversibility and short timeliness; Third, waterproof and breathable device: The breathable membrane and breathable cap utilize the principle of water vapor diffusion. When the lamp is lit inside the lamp, the humid air inside the lamp is discharged outside the lamp through diffusion. The disadvantage is that a large number of them are used and the fog problem in the cold zone of the mask cannot be effectively solved.
[0003] Therefore, in view of the cold zone phenomenon of headlights, it is very necessary to provide a headlight with an efficient defogging and drying device to effectively solve the fog problem of headlights. Summary of the Utility Model
[0004] In view of this, the technical problem to be solved by the utility model is to provide an efficient heat circulation drying device for headlights to avoid the trouble of fogging easily occurring in the lower part and side of conventional headlights.
[0005] To solve the above technical problem, the utility model discloses an efficient heat circulation drying device for headlights. The headlight includes a housing, a lamp cover, a light source, and a decorative ring. The decorative ring is disposed around the front end of the light source. An exhaust hole is provided at the rear side of the housing. A radiator is provided at the rear side of the light source. The radiator is located inside the housing and is provided with a cooling fan. The cooling fan is connected to the input end of an air duct. The air duct is wound around the left and right sides and the bottom of the headlight, and the air duct has a plurality of openings facing the lamp cover.
[0006] According to an embodiment of the utility model, a waterproof and breathable cap is installed on the exhaust hole, and the waterproof and breathable cap has a polytetrafluoroethylene membrane.
[0007] According to an embodiment of the utility model, the cooling fan is laterally installed on the radiator to blow the temperature of the radiator into the input end of the air duct.
[0008] According to an embodiment of the utility model, the air duct is made of plastic or metal and is disposed between the lamp cover and the decorative ring.
[0009] According to an embodiment of the present utility model, the opening interval is 1.5 - 2.5 cm.
[0010] Compared with the prior art, the present utility model can achieve the following technical effects:
[0011] The vehicle lamp light source is equipped with a radiator and a cooling fan itself. The input end of the air duct is fixedly connected to the cooling fan. The openings of the air duct are hidden in the sandwich layer between the lamp shade and the decorative ring below or on the side of the lamp according to the layout of the lamp shape. When people look directly, they cannot see the openings of the air duct.
[0012] When the lamp is powered on and the light is lit, the cooling fan of the light source starts to work, blowing the temperature of the radiator of the light source into the air duct. Then, the hot air gradually blows towards the position where the lamp shade is prone to fogging according to the layout of the air duct, raising the temperature of the lamp shade and promoting air convection, thereby solving the generation of fog.
[0013] Of course, when implementing any product of the present utility model, it is not necessarily required to achieve all the above-mentioned technical effects simultaneously. Description of the Drawings

[0022] Automobile lamps are prone to fogging, and the fog is mainly concentrated below or on the sides of the lamps, which is the so-called "cold area". The utility model aims to provide a device to solve the cold area phenomenon.
[0023] Specifically, the utility model discloses a high-efficiency heat circulation drying device for a vehicle lamp. The vehicle lamp includes a shell 10, a lampshade 20, a light source 30, and a decorative ring 40. The decorative ring 40 is arranged around the front end of the light source 30. An exhaust hole 50 is arranged on the rear side of the shell 10. A radiator 60 is arranged on the rear side of the light source 30. The radiator 60 is located in the shell 10 and is provided with a cooling fan 61. The cooling fan 61 is connected to the input end of an air duct 70. The air duct 70 is arranged around the left and right sides and the bottom of the vehicle lamp, and the air duct 70 has a plurality of openings 71 facing the lampshade 20.
[0024] In one embodiment of the utility model, the vehicle lamp is composed of a housing 10, a lampshade 20, a light source 30, and a decorative ring 40, wherein the decorative ring 40 is a decorative inner part surrounding the light source 30. The light source 30 is now mostly an LED light source, with a heat sink 60, that is, in the shape of an aluminum fin, and a cooling fan 61 is arranged on the rear side. The cooling fan 61 is arranged laterally to cool the radiator 60. The air duct 70 is connected to the cooling fan 61, and the cooling fan 61 blows the hot air generated by the radiator 60 into the air duct 70, and the air duct 70 extends out and is arranged below or on the side of the lamp. Through the opening 71, the area of the lampshade 20 that is prone to fogging is heated and defogging is completed, which is convenient and practical.
[0025] An exhaust hole 50 is provided at the rear side of the lamp housing 10 , and a waterproof breathable cap 80 is installed in the exhaust hole 50 . The waterproof breathable cap 80 has a polytetrafluoroethylene film to complete the waterproof and breathable function inside the housing 10 .
[0026] The heat dissipation fan 61 of the present invention is installed laterally on the radiator 60 to facilitate heat dissipation. At the same time, the lateral arrangement can also blow the temperature of the radiator 60 into the input end of the air duct 70 more smoothly.
[0027] In a preferred embodiment, the air duct 70 is made of plastic or metal and is placed between the lampshade 20 and the decorative ring 40 , closer to the lampshade 20 , so as to facilitate hot air to clear the fog area.
[0028] In addition, the openings 71 of the air duct 70 are spaced 1.5-2.5 cm apart, and the purge interval is properly controlled to make the purge more comprehensive.
[0029] In summary, when the lamp is powered on and the light is lit, the heat dissipation fan of the light source starts to work, blowing the temperature of the radiator of the light source into the air duct. Then, the hot air gradually blows to the position where the lampshade is prone to fogging according to the layout of the air duct, raising the temperature of the lampshade and promoting air convection, thus solving the generation of fog and having strong practicability.
