When a large amount of moisture is adsorbed inside the dry particles 8 after long-term use, hot air can be blown into the inside of the dehumidification box 7 to dry the dry particles 8 and restore the dehumidification effect.

[0028] A dustproof net is fixedly arranged inside the heat dissipation port.

[0029] Symmetrical mounting brackets 20 are fixedly provided on the lower side wall of the cabinet 1 , and mounting bolts are threadedly provided on the side walls of the two mounting brackets 20 .

[0030] The moving mechanism includes a screw rod 21, which is laterally rotatably arranged inside the installation box 2. One end of the screw rod 21 is rotatably connected to the inner wall of the installation box 2, and the other end of the screw rod 21 passes through the installation box 2 and extends to the outside and is fixedly provided with a handle 22. The rod wall of the screw rod 21 is threadedly provided with a slider 23, and the rear side wall of the slider 23 is slidably connected to the inner wall of the installation box 2.
