[0028] The heat preservation plate 101 is arranged in the cabinet body 1 to enhance the isolation effect between the inside and outside of the cabinet body 1, so that the problem of corrosion and rust caused by the large temperature difference between the inside and outside of the cabinet body 1 and the attachment of water mist is avoided.

[0029] The side wall of the cabinet body 1 is provided with a plurality of air inlet and outlet openings, the air inlet and outlet openings are internally provided with fixedly installed air guide fans 103, and the ventilation cover 3 is fixedly installed on the inner side wall of the cabinet body 1 and covers the air inlet and outlet openings.

[0030] It should be noted that the rotating directions of the air guide fans 103 on both sides of the cabinet body 1 are different, one air guide fan 103 draws the air in the ventilation cover 3 out of the cabinet body 1, and the other air guide fan 103 is responsible for sucking the air outside into the ventilation cover 3.

[0031] In the embodiment, the adjusting assembly 4 comprises a servo motor 401 fixedly installed on the inner side walls of the cabinet body 1, a transmission block 402 fixedly installed on the side surface of the output shaft of the servo motor 401, a support frame 403 arranged on the outer side of the transmission block 402, a limiting spring 404 fixedly installed on the side surface of the support frame 403, a ventilation plate 405 fixedly installed on the outer side of the support frame 403, a drying cylinder 406 movably connected in the ventilation plate 405, an adjusting ring 407 fixedly installed on the side surface of the ventilation cover 3, and a wrapping ring 408 fixedly installed on the side surface of the ventilation cover 3.

[0032] The output shaft of the servo motor 401 penetrates the ventilation cover 3 transversely and is rotationally connected with the ventilation cover 3. The transmission block 402 is of a cross-shaped structure and is provided with a limiting plate 409 on the side surface. The limiting spring 404 is slidingly connected on the outside of the transmission block 402 and is fixedly installed on the side surface of the limiting plate 409.

[0033] The inside of the support frame 403 is provided with a cross-shaped notch matched with the transmission block 402. The transmission block 402 penetrates the support frame 403 transversely and is slidingly connected with the support frame 403.

[0034] The cross-shaped notch in the inside of the support frame 403 and the transmission block 402 are matched, so that the rotation of the servo motor 401 can drive the synchronous rotation of the transmission block 402 and the support frame 403, and the support frame 403 can slide transversely on the outside of the transmission block 402.

[0035] The surface of the ventilation plate 405 is provided with a plurality of circumferentially distributed air outlet through holes 410. The side wall of the ventilation cover 3 is provided with a plurality of limiting through holes 411 matched with the air outlet through holes 410. The inner side wall of the limiting through hole 411 is provided with a sealing gasket matched with the drying cylinder 406.

[0036] The sealing gasket is arranged in the limiting through hole 411 to match the drying cylinder 406, so that after the drying cylinder 406 abuts against the limiting through hole 411, air can only circulate through the drying cylinder 406, and needs to be dried whether it enters or exits.

[0037] The inside of the drying cylinder 406 is provided with a drying agent and both sides are provided with filter screens. The drying cylinder 406 is fixedly inserted in the inside of the air outlet through hole 410 and the end portion is embedded in the inside of the limiting through hole 411.

[0038] The drying cylinder 406 is fixedly inserted in the inside of the air outlet through hole 410, which facilitates the timely replacement of the drying agent in the drying cylinder 406, and ensures the drying effect when air circulates.

[0039] It should be noted that the limiting through hole 411 is half the number of the air outlet through hole 410, and the positions of the two are matched with each other, so that air can enter and exit the inside of the cabinet 1 and the ventilation cover 3 along the air outlet through hole 410 and the limiting through hole 411. The drying agent placed in the inside of the drying cylinder 406 can be calcium chloride, gelatinized starch and other high-efficiency adsorbent materials.

[0040] The inner and outer side walls of the ventilation plate 405 are slidingly connected with the outer side wall of the adjusting ring 407 and the inner side wall of the wrapping ring 408, respectively. The side surface of the adjusting ring 407 is provided with a plurality of wedge-shaped blocks 412 matched with the support frame 403.

[0041] The air can only pass through the air outlet through hole 410 on the surface of the ventilation plate 405. The wedge-shaped block 412 is arranged on the side of the adjusting ring 407, so that when the support frame 403 rotates through the wedge-shaped block 412, the support frame 403 is laterally extruded by the wedge-shaped block 412, thereby pushing the support frame 403 to move laterally.

[0042] The working principle of the above embodiment is as follows:

[0043] When the humidity in the cabinet is too high, the servo motor 401 is started to rotate, the rotation of the servo motor 401 drives the transmission block 402 to rotate, thereby driving the support frame 403 to rotate, and the rotation of the support frame 403 drives the ventilation plate 405 and the drying cylinder 406 to rotate. When the drying cylinder 406 rotates to the side of the limiting perforation 411, the extension of the limiting spring 404 extrudes the support frame 403 to move laterally outside the transmission block 402, so that the ventilation plate 405 inserts the drying cylinder 406 into a part of the inside of the limiting perforation 411. The filling of the drying cylinder 406 to the limiting perforation 411 makes the air passing through the limiting perforation 411 need to be dried by the drying cylinder 406, and then the air guide fan 103 is started to work. The air guide fan 103 on one side draws out the air inside the ventilation cover 3, and the air with high humidity in the cabinet 1 is discharged after being dried and adsorbed by the drying cylinder 406. At the same time, the air outside is dried by the drying cylinder 406 on the other side and then enters the inside of the cabinet 1, thereby reducing the humidity inside the cabinet 1.

[0044] In addition, when the humidity in the cabinet is too low, the servo motor 401 is started to rotate, the rotation of the servo motor 401 drives the transmission block 402 to rotate, thereby driving the support frame 403 to rotate, and the support frame 403 moves to be extruded laterally by the wedge-shaped block 412 on the surface of the adjusting ring 407. The lateral movement of the support frame 403 drives the ventilation plate 405 to draw out the drying cylinder 406 from the inside of the limiting perforation 411. The rotation of the servo motor 401 stops running after the limiting perforation 411 and the air outlet through hole 410 are aligned. At this time, the air with high humidity can directly enter and exit the inside of the ventilation cover 3 and the cabinet 1, thereby increasing the humidity of the air inside the cabinet 1.

[0045] The electrical components in the text are electrically connected with the main controller and the power supply. The main controller can be a conventional known device such as a computer, and the existing disclosed power connection technology is not described in detail.
