In order to realize the installation of the shell 1, at least one of the following two ways is adopted:
the first method is as follows:
a convex part 121 extending outwards is arranged on the peripheral side of the cover 12, and a mounting hole 122 is arranged on the convex part 121; preferably, the number of the protrusions 121 is two, and the protrusions are symmetrically distributed on both sides of the cover 12. During installation, bolts with fixed specifications need to pass through the installation holes 122, and the device can be installed on other devices.
The second method comprises the following steps:
a gasket 7 is bonded on one side of the uncovered box body 11, which is back to the opening, and a bonding material is attached to the gasket 7 and used for bonding with other devices, so that the shell 1 is mounted.
The present embodiment further enhances the installation effect of the housing 1 by combining the two methods.
The first air hole 2 is opened on a first side wall of the casing 1, specifically on the cover 12, and is used for wet air to pass through.
The breathable film 3 is tightly attached to the first side wall to seal the first air hole 2, and the breathable film 3 is made of a microporous material, so that the renewable drying agent 6 can be prevented from leaking from the first air hole 2 while the whole ventilation is realized.
The second air hole 4 is formed in a second side wall of the shell 1 relative to the first side wall, specifically on the bottom wall of the uncovered box body 11, and is used for discharging wet air. Adaptively, the gasket 7 is provided with a third air hole 71 at a position corresponding to the second air hole 4 to avoid blocking the wet air.
The elastic membrane 5 is arranged in the second air hole 4, and a cutting seam 51 is arranged in the middle of the elastic membrane 5 to realize one-way circulation of air.
The renewable drying agent 6 is a mixture prepared from magnesium chloride and graphene according to a mass ratio, is arranged in the cavity, and has the characteristics of adsorbing water molecules in the cavity under a normal state and enabling the adsorbed water molecules to be separated from a working state when the temperature is increased.
In order to further enhance the defogging effect, a waterproof breathable film 72 is arranged in the third vent hole 71, the waterproof breathable film 72 is bonded with the gasket 7, and the waterproof breathable film 72 has the characteristic of single-phase circulation of water molecules, so that only the water molecules are allowed to flow from one side of the shell 1 to one side of the gasket 7, and external water vapor is prevented from entering the shell 1.
In order to facilitate the installation of the elastic membrane 5, a connecting sheet 8 with a through middle part is arranged between the waterproof breathable film 72 and the elastic membrane 5, the periphery of the connecting sheet 8 is bonded with the second air holes 4, and the waterproof breathable film 72 and the elastic membrane 5 are bonded with two sides of the connecting sheet 8 respectively.
Example two:
referring to fig. 5, the present embodiment provides a vehicle lamp, which includes a lamp housing 8 and an electronic component 81 disposed in the lamp housing 8 for controlling the on/off of the lamp, wherein the drying device for recycling defogging is disposed in the lamp housing 8 as described in the first embodiment. In order to facilitate the water in the car lamp shell 8 to be led out, the car lamp air holes 82 are formed in the position, corresponding to the second air holes 4, of the car lamp shell 8.
When the lamp is turned on, the electronic component 81 heats up, the temperature in the lamp housing 1 rises, the internal air expands, as shown in fig. 6, the elastic diaphragm 5 deforms under pressure, the slit 51 opens, and the desiccant discharges water vapor. On the contrary, when the car light is turned off, the cutting joint 51 is turned off, the air inside and outside the car light is not circulated, and at the moment, the drying agent continuously absorbs the water vapor in the car light; the circulation realizes the purpose of gradually reducing the water vapor in the car lamp.
