A plurality of air inlets 13 are provided at the bottom right side of the outer shell 1, and a cleaning component is installed inside the outer shell 1. An exhaust port 21 is fixedly connected to the top of the outer shell 1, and a dust cover 22 is fixedly connected to the top of the exhaust port 21. The bottom of the outer frame 3 is slidably connected to the inner bottom wall of the outer shell 1, and the outer periphery of the partition 5 is fixedly connected to the inner wall of the outer shell 1. The right side of the outer wall of the limit rod 2 12 is slidably connected to the inner wall of the insertion rod 10, and the right side of the outer wall of the insertion rod 10 is inserted into the outer frame 3, and the left end of the limit rod 2 12 is fixedly connected to the right side of the rear part of the limit rod 1 7.

[0032] Specifically, the outer shell 1 is used to protect and connect the internal devices and components, the limit bar 2 is used to locate and limit the moving direction of the outer frame 3 to ensure that the outer frame 3 can be accurately inserted into the outer shell 1 without shaking, the outer frame 3 is used to place the dehumidification filter 4, and the dehumidification filter 4 is made of silica gel. Silica gel is an amorphous solid material with good moisture absorption performance. It can absorb moisture in the air and fix it in its pore structure to keep the environment dry. The partition 5 is to isolate the upper and lower spaces of the outer shell 1 to ensure that the air enters the inner part of the outer shell 1 after being processed, the suction fan 6 is used to inhale the air, and the limit rod 7 is In order to limit the movement direction of the pull rod 8, the pull rod 8 is for easy pulling to unlock the device so as to achieve quick fixation and quick disassembly. The connecting rod 9 is used to pull the plug rod 10 to achieve a linkage effect. The plug rod 10 cooperates with the outer frame 3 to achieve quick fixation and removal. The spring 11 is used for resetting. When the pull rod 8 is released, the spring 11 will release kinetic energy to push the plug rod 10 to move. The limit rod 2 12 is used to limit the movement direction of the plug rod 10. The air inlet 13 is used to allow air to enter the outer shell 1. The exhaust port 21 is used to discharge the air in the outer shell 1, and also plays a role in heat dissipation. The dust cover 22 is used to prevent dust from falling in.

[0033] Reference Figure 1 , Figure 4 , Figure 5The cleaning component includes a motor 14, the front side of the motor 14 is fixedly connected to the rear side of the shell 1, the output end of the motor 14 is fixedly connected to a threaded rod 15, the outer wall of the threaded rod 15 is threadedly connected to a slider 16, a plurality of springs 17 are fixedly connected inside the slider 16, a brush 18 is fixedly connected to the right end of the spring 17, a slide rod 19 is slidably connected to the upper side of the slider 16, and a dust removal fan 20 is fixedly connected to the left and right sides of the left part of the slider 16, the front and rear ends of the threaded rod 15 are rotatably connected to the inside of the shell 1, the front and rear ends of the slide rod 19 are fixedly connected to the inner wall of the shell 1, the outer periphery of the brush 18 is slidably connected to the inside of the slider 16, and the brush 18 abuts against the inner wall of the shell 1.

[0034] Specifically, the motor 14 controls the rotation of the threaded rod 15, and the threaded rod 15 drives the slider 16 to move forward and backward. The spring 17 inside the slider 16 presses against the brush 18 to allow the brush 18 to contact the shell 1. The brush 18 is used to sweep away the dust attached to the air inlet 13. The slide bar 19 is used to limit the movement direction of the slider 16 to ensure that the slider 16 will not move around and can only move forward and backward. The dust removal fan 20 is used to blow out the dust swept by the brush 18 immediately to prevent it from falling into the shell 1, thereby ensuring the normal operation of its internal equipment.

[0035] Working principle: when the dehumidification filter 4 needs to be replaced, first pull the pull rod 8, drive the connecting rod 9 to pull the plug 10, unlock it from the inside of the outer frame 3, and pull out the outer frame 3, then remove the used dehumidification filter 4, and replace it with a new dehumidification filter 4. At this time, pull the pull rod 8 again, drive the connecting rod 9 to pull the plug 10, and reinsert the outer frame 3 into the outer shell 1, and then release the pull rod 8. The spring 11 will push the plug 10 to insert into the inner part of the outer frame 3, thereby realizing quick removal and quick fixation. The suction fan 6 can work normally by controlling the external power supply. When the equipment has been used for a period of time, some dust will adhere to the air inlet 13. At this time, it needs to be cleaned in time. First, close the suction The fan 6 controls the motor 14 and the dust removal fan 20 to rotate through an external power supply. The rotation of the motor 14 drives the threaded rod 15 to rotate. Under the limit of the slide bar 19, the slider 16 is driven to move forward and backward. The slider 16 moves forward and backward together with the brush 18. The spring 17 pushes the brush 18 to firmly press the brush 18 against the inner wall of the shell 1. When the brush 18 sweeps the dust down, the dust removal fan 20 will immediately blow the dust out from the air inlet 13. After cleaning, the suction fan 6 can be controlled again to be used normally. The ventilation effect of the equipment after cleaning is effectively improved, and the phenomenon of reduced dehumidification effect due to excessive dust blocking the air inlet 13, thereby causing electrical equipment failure and damage, is avoided.
