[0007] In one preferable embodiment of the utility model, the buckle is a T-shaped buckle arranged at intervals on the circumference of the shell.

[0008] In one preferable embodiment of the utility model, the shell is provided with an arc-shaped convex rib below the buckle, and a sealing ring is arranged on the arc-shaped convex rib.

[0009] In one preferable embodiment of the utility model, the reversible desiccant is a magnesium salt desiccant or a silica gel desiccant or a montmorillonite desiccant.

[0022] Please refer to Figures 1 to 3 A replaceable dehumidification device, comprising a shell 1 with two ends through, the shell 1 has a plurality of buckles 2 on the circumference, the shell 1 is detachably connected to the external equipment through the buckle 2. The buckle 2 is a T-shaped buckle arranged at intervals on the circumference of the shell 1. The dehumidification device is connected to the external equipment through the buckle 2, ensuring that the narrow space inside the external equipment can be communicated with the outside, and the internal humidity can be absorbed by the dehumidification device and discharged to the outside.

[0023] The shell 1 has an arc-shaped convex rib 3 below the buckle 2, and a sealing ring 4 is arranged on the arc-shaped convex rib 3. The sealing ring 4 can ensure the sealing between the dehumidification device and the equipment, so that the shell 1 becomes the only air flow passage. The external equipment is a car lamp, a battery pack or a camera with a narrow internal space.

[0024] The inside of the shell 1 is filled with reversible desiccant 5. The shell 1 is connected with a breathable film 6 and a cover plate 7, and the breathable film 6 is located above the reversible desiccant 5. The reversible desiccant 5 is a magnesium salt desiccant or a silica gel desiccant or a montmorillonite desiccant. The breathable film 6 is a PTFE film or an ePTFE film. When the humidity in the environment is large, the water molecules in the air are absorbed by the reversible desiccant 5 through the cover plate 7 and the breathable film 6, and when the environment is relatively dry, the water vapor of the reversible desiccant 5 is released to the outside air through the cover plate 7 and the breathable film 6, so as to ensure that the inside of the dehumidification device is dry.

[0025] The breathable film 6 and the cover plate 7 can be connected with the shell 1 in two different ways. One is to weld the breathable film 6 with the upper end of the shell 1 first, and then weld the cover plate 7 with the upper end of the shell 1. The second is to weld the breathable film 6 directly at the bottom of the cover plate 7 to make them into a whole, and then weld the whole on the upper end of the shell 1. The breathable holes on the cover plate 7 can be circular, square or other common geometric shapes.

[0026] Different from the prior art, the utility model discloses a replaceable dehumidification device, adopts detachable replacement structure, simplifies installation mode, reduces manufacturing cost and has good dehumidification effect.

[0027] The utility model has been described above in a schematic manner and its embodiments, and the description is not restrictive, and the drawings only show one of the embodiments of the utility model, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by the utility model, without departing from the creative purpose of the utility model, similar structural modes and embodiments are not creatively designed, and all should belong to the protection scope of the utility model.
