Two vertical screw rods 7 are dynamically installed, and moving blocks 8 are threadedly sleeved on the two vertical screw rods 7. The two moving blocks 8 are fixedly installed on the sides of the air intake hood 4 and the air outlet hood 6 respectively. The air intake hood 4 and the air outlet hood 6 are installed with vertical guide units. A servo motor 9 is fixedly installed on the bottom inner wall of the control cabinet 1. The bottom end of one of the vertical screw rods 7 is fixedly installed on the output end of the servo motor 9. A synchronous rotation unit is commonly connected to the two vertical screw rods 7. A sealed box cover 10 is arranged on the top of the drying box 3. Two convenient disassembly and assembly units for fixing the sealed box cover 10 are symmetrically installed on the drying box 3. A humidity sensor 20 is fixedly provided on the top inner wall of the control cabinet 1.

[0023] By means of the above structure and the setting of the humidity sensor 20, the air humidity in the control cabinet 1 can be monitored in real time. When it is detected that the air humidity is high, the vacuum pump 2 and the servo motor 9 can be started. The operation of the vacuum pump 2 will automatically draw the humid air in the control cabinet 1 into the drying box 3 through the first hose and the air suction hood 4 for drying, and then discharge the dried air into the control cabinet 1 through the connecting pipe 5, the second hose and the air outlet hood 6, so as to achieve the purpose of circulating and drying the humid air in the control cabinet 1, and the dehumidification effect is good. The operation of the servo motor 9 will drive one of the vertical screws 7 to rotate, and under the action of the synchronous rotation unit, it will drive the other vertical screw 7 to rotate synchronously. At this time, under the cooperation of the vertical guide unit, the synchronous rotation of the two vertical screws 7 will drive the air suction hood 4 and the air outlet hood 6 to move up and down at the same time through the moving block 8, so that the humid air in the control cabinet 1 can be automatically and evenly and comprehensively circulated and dried, and the dehumidification effect is better. The structure is simple, the use is convenient, and the practicability is good.

[0024] As a preferred implementation of this embodiment, the synchronous rotation unit includes two transmission pulleys 11 respectively fixedly sleeved on the two vertical screw rods 7, and a transmission belt 12 is tensioned on the two transmission pulleys 11. The advantage of this arrangement is that when one of the vertical screw rods 7 rotates, it will drive one of the transmission pulleys 11 to rotate. At this time, under the action of the transmission belt 12, the other transmission pulley 11 will be driven to rotate together, and then the other vertical screw rod 7 will be driven to rotate synchronously, playing a role of synchronous transmission.

[0025] As a preferred implementation of this embodiment, the vertical guide unit includes two vertical guide rods 13 fixedly mounted on the inner wall of the bottom of the control cabinet 1, and guide blocks 14 are slidably sleeved on the two vertical guide rods 13, and the two guide blocks 14 are respectively fixedly mounted on the sides of the air suction hood 4 and the air outlet hood 6. The advantage of this arrangement is that, through the coordinated arrangement of the vertical guide rods 13 and the guide blocks 14, the air suction hood 4 and the air outlet hood 6 can only move vertically up and down, and will not rotate with the vertical screw 7, which plays a role of vertical guidance and has good stability during operation.

[0026] As a preferred implementation of this embodiment, the convenient disassembly unit includes a first L-shaped fixing piece 15 fixedly mounted on the side of the drying box 3, a second L-shaped fixing piece 16 matched with the first L-shaped fixing piece 15 is fixedly mounted on the side of the sealed box cover 10, a rod sliding hole is provided on the side of the first L-shaped fixing piece 15, a fixed rod 17 is slidably mounted in the rod sliding hole, a fixed plug hole is provided on the side of the second L-shaped fixing piece 16, one end of the fixed plug rod 17 passes through the fixed plug hole, and a control pull block 18 is fixedly mounted on the other end of the fixed plug rod 17, and a reset element is mounted on the control pull block 18. The advantage of such a setting is that when the control pull block 18 is moved left and right, the fixed plug rod 17 will be driven to move in or out of the fixed plug hole, and then the second L-shaped fixing piece 16 and the sealed box cover 10 can be fixed or loosened, thereby achieving the purpose of facilitating the staff to quickly open the sealed box cover 10 to replace the desiccant in the drying box 3, and the practicality is better.

[0027] In this embodiment, the reset element includes a reset spring 19 sleeved on the fixed plug rod 17, and the two ends of the reset spring 19 are respectively fixedly mounted on the side of the first L-shaped fixed sheet 15 and the control pull block 18. The advantage of this arrangement is that when the control pull block 18 is released, the elastic force of the reset spring 19 will pull the control pull block 18 to automatically reset, and then the fixed plug rod 17 can be automatically inserted into the fixed plug hole, and the second L-shaped fixed sheet 16 and the sealed box cover 10 can be automatically fixed, and the fixed state can be maintained all the time, which is stable and reliable.

[0028] As a preferred implementation of this embodiment, a sealing gasket 21 is fixedly arranged at the bottom of the sealing box cover 10. The advantage of such an arrangement is that the sealing performance between the sealing box cover 10 and the drying box 3 can be effectively increased by the arrangement of the sealing gasket 21, and the sealing effect is better.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
