[0001] The utility model relates to the technical field of automobile auxiliary tools, in particular to a waterproof, demisting, drying and ventilating component for automobile lamps. Background Art
[0002] Since car lights need air vents to balance the pressure difference between the inside and the outside, after the car lights are turned off, the temperature inside the car lights continues to cool down, the pressure inside the car lights drops, and the outside air mixed with moisture will enter the car lights through the air vents. The moisture will form fog on the inner wall of the car lights, affecting driving safety. Therefore, a waterproof, defogging, drying and breathable component for car lights has emerged.
[0003] Although current technology has many advantages, its disadvantage is that it can only evaporate the mist through the heat when the lights are turned on, and then discharge the mist through the high pressure inside the lights, which takes a long time and cannot solve the problem of fog condensation after the lights are turned off. At the same time, current technology mostly uses threaded connections when installing waterproof, defogging, drying and breathable components on the car. However, since the car shakes during driving, the threads of the waterproof, defogging, drying and breathable components are prone to wear. Once the threads are worn, the position of the waterproof, defogging, drying and breathable components will shift, affecting the use effect. Utility Model Content

[0006] As a preferred embodiment, two L-shaped grooves are provided on the side of the outer surface of the lamp body close to the mounting groove, guide grooves are provided on the inner surfaces of the two L-shaped grooves, fixing grooves are provided on the side of the inner surfaces of the two L-shaped grooves away from the two guide grooves, moving blocks are movably embedded in the inner surfaces of the two guide grooves, pushing blocks and fixing blocks are fixedly connected to the outer surfaces of the two moving blocks, springs are fixedly connected to the sides of the two moving blocks away from the two pushing blocks, and positioning rods are fixedly connected to the ends of the springs away from the two moving blocks. In this way, the waterproof, defogging, drying and breathable assembly can be fixed inside the lamp body by moving the two moving rods, thus avoiding the problem of displacement of the waterproof, defogging, drying and breathable assembly caused by threaded installation.
[0007] As a preferred implementation, the desiccant is filled on the inner surface of the working block, and the desiccant can absorb moisture inside the headlight when the headlight is turned off.
[0008] As a preferred embodiment, two fixing rods are fixedly connected to one side of the outer surface of the working block close to the waterproof breathable membrane, and the fixing rods can be stuck in the L-shaped groove to provide a good working environment for the working block.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:
[0014] 1. In the utility model, the ventilation component is welded with waterproof breathable membrane 1 and waterproof breathable membrane 2 on the upper and lower parts, and there is a ventilation channel in the middle, which can not only achieve the air pressure balance inside and outside the headlight, but also prevent the external liquid water, dust, pollutants, etc. from entering the interior of the headlight. The waterproof breathable membrane 1 and the bottom plate are filled with a desiccant, which can absorb the moisture inside the headlight when the headlight is off, and can prevent the desiccant from contacting the outside world. Therefore, the silica gel desiccant can use the heat when the headlight is on to discharge the absorbed moisture, so that the desiccant is effective for a long time. The air permeability rate of the waterproof breathable membrane 2 is much higher than that of the waterproof breathable membrane 1. It should be small, so that the internal gas of the working block can be quickly exhausted to the outside through the air duct, and the external moisture can be prevented from quickly entering the interior of the headlight. The sealing ring on the top of the baffle ensures its sealing, which can not only achieve the air pressure balance inside and outside the headlight, but also prevent the external liquid water, dust, pollutants, etc. from entering the interior of the headlight, and absorb the moisture inside the headlight when the headlight is off, effectively solving the problem of fogging of the headlight, effectively extending the life of the lamp beads, and easy installation, saving costs.

Then, the working block is aligned with the installation groove on the lamp body, the two fixed rods are aligned with the two L-shaped grooves, the working block is placed in the lamp body, and then the working block is rotated. The two moving blocks drive the two fixing rods to move to the innermost part of the horizontal grooves of the two L-shaped grooves, and then the two moving rods are released. The two springs release the elastic potential energy, so that the two moving blocks drive the two pushing blocks and the fixing blocks to move, so that the two fixing blocks are inserted into the two fixing grooves, and the two pushing blocks are inserted into the horizontal grooves of the L-shaped grooves, and the two fixing rods are squeezed to fix the two fixing rods in the horizontal grooves of the L-shaped grooves. In this way, the waterproof, defogging, drying and breathable assembly can be fixed inside the lamp body by moving the two moving rods, avoiding the problem of deviation of the waterproof, defogging, drying and breathable assembly caused by threaded installation, thereby improving the user's use effect.

A desiccant 6 is filled between the waterproof breathable membrane 1 4 and the bottom plate 8. The desiccant 6 is made of silica gel, which can absorb the moisture inside the headlight when the headlight is off, and the bottom plate 8 is made of plastic, which can prevent the desiccant 6 from contacting the outside world. Therefore, the silica gel desiccant 6 can use the heat when the headlight is on to discharge the absorbed moisture, so that the desiccant 6 is effective for a long time, and the waterproof breathable membrane 2 The hole of 9 is much smaller than that of the waterproof breathable membrane 14, so the air permeability rate of the waterproof breathable membrane 2 9 is much smaller than that of the waterproof breathable membrane 14, so that the internal gas of the working block 3 can be quickly exhausted to the outside through the air duct 5, and the external moisture can be prevented from quickly entering the interior of the headlight. The material of the sealing ring 11 is silicone rubber, and its sealing is ensured by the sealing ring 11 on the top of the baffle 10, so that the air pressure inside and outside the headlight can be balanced, and liquid water, dust, pollutants, etc. from the outside can be prevented from entering the interior of the headlight, and the moisture inside the headlight can be absorbed when the headlight is turned off, effectively solving the problem of fogging of the headlight, effectively extending the life of the lamp beads, and easy installation, saving costs.
