Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to a drying device. Background Art

[0002] With the development of the automobile industry, car lights have become an indispensable accessory, evolving from traditional halogen headlights to technologically innovative xenon headlights, and then to the widely used LED headlights today.

[0003] However, the compact and complex design of LED headlights limits the air circulation inside the headlights to a certain extent. This causes a temperature difference inside the headlights in cold areas, after long-term use, or when the temperature changes seasonally, which in turn causes the water vapor in the headlight mask to condense into water droplets and form fog. This phenomenon not only affects the lighting effect of the headlights, but also poses a potential threat to driving safety and vehicle appearance.

[0004] Currently, the commonly used method is to put physical desiccants such as magnesium oxide, silica gel and mineral desiccants or chemical desiccants such as magnesium chloride and calcium chloride into the headlights to keep the internal environment of the headlights dry. However, if air containing moisture enters the headlights directly, fog will still appear. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a drying device, comprising a container body, wherein the container body is provided with a through-going air hole;

[0006] An outer shell is disposed at one side end of the container body, a first passage for air circulation is formed between the outer shell and the container body, and the first passage is connected with the air vent and the outer shell hole;

[0007] An inner shell is disposed at the other side end of the container body, and another second channel for air circulation is formed between the inner shell and the container body, and the second channel is connected with the air vent and the inner shell hole.

[0008] Preferably, a downwardly opening accommodating cavity is provided in the container body, and the accommodating cavity and the air vent are staggered with each other.

[0017] Technical effects and advantages of the utility model:

[0018] In the utility model, air enters the first channel between the outer shell and the container body through the breathable membrane, and enters the second channel between the inner shell and the container body through the breathable hole, which can effectively reduce the rate at which moisture from the external air enters the interior of the car lamp. The moisture is absorbed by the desiccant in the container body to prevent moisture from entering the interior of the car lamp, thereby reducing the humidity inside the car lamp, thereby reducing the dew point temperature and reducing the possibility of fog generation.
