The first clamping plate 303 is arranged at the bottom of the top cover 2, and a first positioning hole 304 is opened on one side of the first clamping plate 303. A limiting ring 305 is fixedly installed on the top of the first clamping plate 303, and a first servo motor 306 is fixedly installed on one side of the limiting ring 305. An external thread block 307 is fixedly installed on the output end of the first servo motor 306, and an internal thread plate 308 is threadedly sleeved on one side of the external thread block 307. A snap ring 309 is fixedly installed on the bottom of the internal thread plate 308, and a clamping block 310 is movably connected to the bottom of the snap ring 309. The dust removal mechanism 3 also includes a dust screening net 301, a first air duct 302, a filter box 311, a second clamping plate 312 and a filter plate 313.

[0024] The filter sheet 313 is composed of four groups of filter screens. The second clamping plate 312 is fixedly mounted on the top of the second gear 404 . The first air guide pipe 302 is connected to the filter box 311 .

[0025] The first clamping plate 303 is fixedly mounted on the top of the filter box 311 , and the internal thread plate 308 is movably sleeved on one side of the output end of the first servo motor 306 .

[0026] It needs to be further explained that: when it is necessary to replace the filter box 311 to clean the dust inside the filter box 311, the first servo motor 306 is started to drive the external thread block 307 to rotate clockwise. At this time, the internal thread plate 308 moves upward with the rotation of the external thread block 307, further driving the retaining ring 309 at the bottom of the internal thread plate 308 to move upward at the same time, thereby disengaging from the retaining block 310. At this time, the filter box 311 and the retaining block 310 can be manually taken out between the second clamping plate 312 and the first clamping plate 303, and then the new filter box 311 is placed in the corresponding position, and the first servo motor 306 is controlled to rotate counterclockwise, thereby driving the retaining ring 309 to move downward and engage with the retaining block 310 again. At this time, the filter box 311 and the retaining block 310 are fixed between the first clamping plate 303 and the second clamping plate 312, completing the fixation of the filter box 311.

[0027] like Figure 6 and Figure 7 As shown, the self-circulation mechanism 4 includes a first partition 401, a second servo motor 402, a first gear 403, a second gear 404, a second positioning hole 405, a power module 406, a sealing tube 407, a swivel 411 and a bearing base 412, the first partition 401 is fixedly installed on one side of the first housing 1, the second servo motor 402 is fixedly installed on the top of the first partition 401, the first gear 403 is fixedly installed on the output end of the second servo motor 402, one side of the first gear 403 is meshed and driven with the second gear 404, one side of the second gear 404 is provided with a second positioning hole 405, one side of the second gear 404 is fixedly installed with a power module 406, the bottom of the second positioning hole 405 is fixedly installed with a sealing tube 407, the bottom of the sealing tube 407 is fixedly connected with a swivel 411, and the bottom of the swivel 411 is movably installed with a bearing base 412; The self-circulation mechanism 4 also includes a power supply plate 408, a first refrigerator 409, a sealing gasket 410 and a third positioning hole 413. The power supply plate 408 is fixedly installed on the top of the sealing tube 407. The bottom of the power supply plate 408 is electrically connected to the first refrigerator 409. A sealing gasket 410 is provided at the bottom of the first refrigerator 409. The sealing gasket 410 is fixedly installed on the top of the rotating ring 411. The third positioning hole 413 is opened on one side of the bearing base 412, and the third positioning hole 413 is connected to the sealing gasket 410.

[0028] The sealing tube 407 is in communication with the sealing gasket 410 , and the power module 406 is electrically connected to the power supply sheet 408 .

[0029] The sealing gasket 410 is movably connected to the top of the bearing base 412 , and the power supply sheet 408 is arranged at the bottom of the second positioning hole 405 .

[0030] It needs to be further explained that: when the dehumidifier unit is used for a long time and water droplets are condensed on the heat sink of the first refrigerator 409, it is necessary to clean the frozen water droplets, and the second servo motor 402 is started to drive the first gear 403 to rotate clockwise, thereby driving the first gear 403 and the second gear 404 to engage and transmit. At this time, the second positioning hole 405 at the top of the second gear 404 and the sealing tube 407 at the bottom of the second gear 404, the first refrigerator 409 and the rotating ring 411 rotate at the top of the bearing base 412 at the same time. When the second positioning hole 405 and the first refrigerator 409 located directly below the first air guide pipe 302 move from directly above the first air guide hole 501 to the second air guide hole 502 as the second gear 404 rotates, the second servo motor 402 stops, the second gear 404 remains different, and the heater 50 is started. The blower connected to one side of the blower hole 511 blows the hot air heated inside the heater 508 through the second air guide hole 502 to the inside of the sealed tube 407. At this time, the hot air heats the heat sink on the first refrigerator 409, and the evaporated water vapor is discharged through the second positioning hole 405. Then the second servo motor 402 is started to drive the second gear 404 to rotate until the sealed tube 407 heated in the previous step moves to the top of the third air guide hole 503. At this time, the hot air inside the heater 508 performs secondary heating treatment on the first refrigerator 409 inside the sealed tube 407 through the third air guide hole 503 to avoid residual water vapor on the heat sink on the first refrigerator 409. At this time, another group of sealed tubes 407 moves to the bottom of the first air guide pipe 302 with the rotation of the second gear 404 and is connected to the outside air, without affecting the interaction between the inside and outside air.

[0031] like Fig. 9 and Fig.10As shown, the air handling mechanism 5 includes a first air guide hole 501, a second air guide hole 502, a third air guide hole 503, a fourth air guide hole 504, a three-pronged pipe 505, a first air hole 506, a second air hole 507, a heater 508, a first heating hole 509, a second heating hole 510, a blast hole 511 and an ultraviolet lamp 512. The first air guide hole 501, the second air guide hole 502, the third air guide hole 503 and the fourth air guide hole 504 are all opened on the top of the first partition plate 401, and the bottom of the first air guide hole 501 is connected to the three-pronged pipe 505. A first air hole 506 is opened on one side of the bottom of the fork tube 505, a second air hole 507 is opened on the other side of the bottom of the three-fork tube 505, the bottom of the second air guide hole 502 is connected to the first heating hole 509, the bottom of the third air guide hole 503 is connected to the second heating hole 510, the first heating hole 509 and the second heating hole 510 are both opened on the top of the heater 508, a blast hole 511 is opened on one side of the heater 508, the bottom of the fourth air guide hole 504 is connected to the ultraviolet lamp 512, and the ultraviolet lamp 512 is fixedly installed on the bottom of the first partition 401.

[0032] The air handling mechanism 5 also includes a first refrigeration group 51, a second refrigeration group 52, a side plate 513, an exhaust hole 514 and a second partition 515. The first refrigeration group 51 and the second refrigeration group 52 are symmetrically arranged with the second partition 515 as the center. The second partition 515 is fixedly installed inside the first shell 1. The side plate 513 is fixedly installed on one side of the second partition 515. The exhaust hole 514 is opened on one side of the first shell 1. The first refrigeration group 51 and the second refrigeration group 52 both include a second refrigerator 516, a first heat sink 517, a second shell 518, a second heat sink 519 and an air inlet 520. The second refrigerator 516 is fixedly installed on one side of the side plate 513. The first heat sink 517 is fixedly installed on one side of the second refrigerator 516. A second shell 518 is provided on one side of the second refrigerator 516. A second heat sink 519 is fixedly installed on one side of the second shell 518. An air inlet 520 is opened on the top of the second shell 518.

[0033] The first heat sink 517 is disposed on one side of the second heat sink 519 , and the second refrigerator 516 , the first heat sink 517 , the second housing 518 and the second heat sink 519 together form an S-shaped cavity.

[0034] The air inlet hole 520 inside the first refrigeration group 51 is connected to the first air hole 506, the air inlet hole 520 inside the second refrigeration group 52 is connected to the second air hole 507, the exhaust hole 514 is connected to the vacuum pump, and the vacuum pump is arranged on the outside of the first shell 1, and the first refrigeration group 51 and the second refrigeration group 52 are connected to the first heater 603 through the second air duct 602.

[0035] It needs to be further explained that: when the interior of the room needs to be cooled, the second refrigerator 516 inside the first cooling group 51 and the second cooling group 52 is started to cool the air passing through the second refrigerator 516, the first heat sink 517 and the second heat sink 519. At this time, the air moves along the S-shaped cavity curve formed by the second refrigerator 516, the first heat sink 517, the second shell 518 and the second heat sink 519, and enters the interior of the S-shaped cavity through the air inlet 520. After cooling, it enters the interior of the first heater 603 and the second heater 604 through the second air duct 602, and finally enters the interior of the room. If heating is required, the heating devices inside the first heater 603 and the second heater 604 are started to heat the air. The first cooling group 51 and the second cooling group 52 are only used as passage pipes.

[0036] The working principle and usage process of the present invention: During the use of the present invention, when the filter box 311 needs to be replaced to clean the dust inside the filter box 311, the first servo motor 306 is started to drive the external thread block 307 to rotate clockwise. At this time, the internal thread plate 308 moves upward with the rotation of the external thread block 307, further driving the retaining ring 309 at the bottom of the internal thread plate 308 to move upward at the same time, thereby disengaging from the retaining block 310. At this time, the filter box 311 and the retaining block 310 can be manually taken out between the second clamping plate 312 and the first clamping plate 303, and then the new filter box 311 is placed in the corresponding position, and the first servo motor 306 is controlled to rotate counterclockwise, thereby driving the retaining ring 309 to move downward and engage with the retaining block 310 again. At this time, the filter box 311 and the retaining block 310 are fixed between the first clamping plate 303 and the second clamping plate 312, completing the fixation of the filter box 311.

[0037] Next, the second servo motor 402 is started to drive the first gear 403 to rotate clockwise, thereby driving the first gear 403 to mesh with the second gear 404. At this time, the second positioning hole 405 at the top of the second gear 404 and the sealing tube 407, the first refrigerator 409 and the rotating ring 411 at the bottom of the second gear 404 rotate at the top of the bearing base 412 at the same time. When the second positioning hole 405 and the first refrigerator 409 located directly below the first air guide pipe 302 move from directly above the first air guide hole 501 to the second air guide hole 502 as the second gear 404 rotates, the second servo motor 402 is stopped, the second gear 404 remains different, and the heater 508 is heated by starting the blower connected to one side of the blow hole 511. The hot air is blown to the inside of the sealed tube 407 through the second air guide hole 502. At this time, the hot air heats the heat sink on the first refrigerator 409, and the evaporated water vapor is discharged through the second positioning hole 405. Then the second servo motor 402 is started to drive the second gear 404 to rotate until the sealed tube 407 heated in the previous step moves to the top of the third air guide hole 503. At this time, the hot air inside the heater 508 performs secondary heating treatment on the first refrigerator 409 inside the sealed tube 407 through the third air guide hole 503 to avoid residual water vapor on the heat sink on the first refrigerator 409. At this time, another group of sealed tubes 407 moves to the bottom of the first air guide tube 302 with the rotation of the second gear 404 and is connected to the outside air, without affecting the interaction between the inside and outside air.

[0038] Finally, when the room needs to be cooled, the vacuum pump is connected to the exhaust hole 514, and the vacuum pump is started to extract the air inside the closed cavity formed by the first shell 1, the side plate 513 and the third partition 601, and then the second refrigerator 516 inside the first refrigeration group 51 and the second refrigeration group 52 is started to cool the air passing through the second refrigerator 516, the first heat sink 517 and the second heat sink 519. At this time, the air moves along the S-shaped cavity curve formed by the second refrigerator 516, the first heat sink 517, the second shell 518 and the second heat sink 519, and enters the interior of the S-shaped cavity through the air inlet 520. After cooling, it enters the interior of the first heater 603 and the second heater 604 through the second air duct 602, and finally enters the interior of the room. If heating is required, the heating device inside the first heater 603 and the second heater 604 is started to heat the air. The first refrigeration group 51 and the second refrigeration group 52 are only used as passage pipes.
