The outer surface of the rotating disk 27 is symmetrically provided with grooves 31, and the inner wall of the box body 1 is symmetrically provided with limit holes for being engaged with the outer end of the rectangular rack 25. When in use, it is only necessary to hold the groove 31 with your fingers, and the groove 31 drives the rotating disk 27 and the slider 30 to rotate counterclockwise for a certain angle. At this time, the rotating disk 27 drives the rectangular rack 25 to move toward each other through the spur gear 26, so that the protective plate 22 is deflected 90 degrees to reach an open or closed state. When the dehumidification plate 23 is disassembled and assembled, the slider 30 is reset in the movable groove 28 as the second spring 29 is reset, so that the rectangular rack 25 is fixed to the inner wall of the box body 1. The structure is simple and the operation is convenient, which improves the drying effect and disassembly efficiency of the device.

[0026] like Figure 1-6 As shown, a door 3 is hingedly connected to the outer surface of the box body 1, an observation window 4 is provided on the surface of the door 3, a lock hole 5 is provided on one side of the surface of the door 3, and supports 2 are fixedly connected to the four corners of the lower surface of the box body 1. The design of the observation window 4 makes it easy to observe the situation inside the box body 1 in real time.

[0027] like Figure 1-6 As shown, the dustproof mechanism includes a first dustproof net 12, the first dustproof net 12 is symmetrically clamped on the outer wall of the box body 1, the inner surface of the first dustproof net 12 is symmetrically fixedly connected with a connecting block 13, a fixing plate 14 is slidably connected between the two groups of connecting blocks 13, and the first dustproof net 12 is sleeved at the air inlet of the outer surface of the box body 1, the innermost end of the inner wall of the box body 1 is symmetrically fixedly connected with the fixing plate 14, the outermost end of the inner wall of the box body 1 is symmetrically fixedly connected with a mounting block 16, and the inner end of the second dustproof net 15 is clamped and connected with the fixing plate 14, the inner cavity of the mounting block 16 is fixedly connected with a first spring 17, and one end of the first spring 17 is fixedly connected with The surfaces of the positioning rod 18 and the mounting block 16 are provided with a limiting groove 20, and the surfaces of the positioning rod 18 are fixedly connected with a push-pull block 19, and the push-pull block 19 is slidably connected to the limiting groove 20. Through the design of the dustproof mechanism, when the first dustproof net 12 and the second dustproof net 15 are disassembled and cleaned, it is only necessary to push the push-pull block 19 to slide in the limiting groove 20 and compress the first spring 17, so that the positioning rod 18 releases the positioning of the second dustproof net 15, and then the second dustproof net 15 is slid and removed from the connecting block 13, thereby completing the disassembly and cleaning of the first dustproof net 12 and the second dustproof net 15, thereby improving the heat dissipation effect and dustproof effect of the device.

[0028] like Figure 1-6 As shown, the processing mechanism includes a processing box 6, a cooling plate 7 is fixedly provided on the upper surface of the processing box 6, an exhaust hole 8 is fixedly provided on the upper surface of the cooling plate 7, and the bottom end of the exhaust hole 8 extends through the inner cavity of the processing box 6, the inner wall of the processing box 6 is symmetrically fixedly provided with a water collecting trough 9, the outer wall of the box body 1 is symmetrically fixedly provided with a drain pipe 10, and the surface of the drain pipe 10 is provided with a solenoid valve 11, and the top of the processing box 6 is an inner triangle. When the hot air inside the box body 1 is discharged through the top, it will be gathered to the inner top wall of the processing box 6, and the cooling plate 7 will cool the processing box 6. When the hot air discharged from the box body 1 contacts the low temperature of the inner top wall of the processing box 6, it will condense into water droplets. The water droplets slide to both sides along the inner bottom wall of the processing box 6 and fall into the water collecting trough 9 for collection, which greatly reduces the water content of the air on the outer surface of the box body 1 and further improves the drying effect of the device.

[0029] Working principle: When the interior of the box body 1 is subjected to moisture-proof treatment, the dehumidification motor 24 discharges the air containing water in the inner cavity of the box body 1 to the top of the box body 1 through the filter plate 21 and the dehumidification plate 23. The dehumidification plate 23 can adsorb a part of the moisture in the air to a certain extent, and the other part of the air containing water enters the treatment box 6. The hot air inside the box body 1 is discharged through the top and gathered to the inner top wall of the treatment box 6, and the cooling plate 7 cools the treatment box 6. When the hot air discharged from the inside of the box body 1 contacts the low temperature of the inner top wall of the treatment box 6, it condenses into water droplets. The water droplets slide to both sides along the inner bottom wall of the treatment box 6 and fall into the water collection tank 9 for collection, which greatly reduces the water content of the air on the outer surface of the box body 1. When the water storage in the treatment box 6 reaches saturation, the solenoid valve 11 is opened to discharge it to the outside from the drain pipe 10. After long-term use, the dehumidification effect of the dehumidification plate 23 deteriorates and needs to be replaced. When replacing, just hold the groove 31 with your finger, and the groove 31 drives the rotating disk 27 , the slider 30 rotates counterclockwise for a certain angle. At this time, the rotating disk 27 drives the rectangular rack 25 to move toward each other through the spur gear 26, so that the protective plate 22 is deflected 90 degrees to reach an open or closed state. When the dehumidification plate 23 is replaced, the slider 30 is reset in the movable groove 28 with the reset of the second spring 29, so that the rectangular rack 25 is fixed to the inner wall of the box body 1. At the same time, after long-term use, the first dustproof net 12 and the second dustproof net 15 will be blocked and affect the dustproof effect. When the first dustproof net 12 and the second dustproof net 15 are disassembled and cleaned, it is only necessary to push the push-pull block 19 to slide in the limit groove 20 and compress the first spring 17, so that the positioning rod 18 releases the positioning of the second dustproof net 15, and then the second dustproof net 15 is slid and removed from the connecting block 13, thereby completing the disassembly and cleaning of the first dustproof net 12 and the second dustproof net 15. The overall structure is simple and easy to operate, which improves the drying effect and disassembly and assembly efficiency of the device and is suitable for large-scale promotion.
