[0021] Compared with the prior art, the present invention has at least the following beneficial effects:

[0022] 1. A dual cold source fresh air dehumidification unit with an explosion-proof structure. By setting a filter box and rotating multiple filter boxes for use, it avoids the too fast accumulation speed of dust inside the filter box during the long-term use of the dehumidification unit, thus eliminating the need for frequent manual replacement of the filter box to clean the dust inside the filter box, reducing the usage burden of the dehumidification unit.

[0023] 2. A dual cold source fresh air dehumidification unit with an explosion-proof structure. By setting a second gear, rotating the second gear drives the first refrigerator and the second positioning hole inside the sealing tube to rotate, successively passing through the hot air device and the ultraviolet disinfection device inside the air treatment mechanism to heat and disinfect the inside of the sealing tube. It can dry the water droplets condensed and adsorbed on the surface of the first refrigerator, avoiding the freezing of water droplets on the surface of the first refrigerator after long-term use, which affects the service life of the first refrigerator. At the same time, it disinfects the first refrigerator and the second positioning hole, preventing germs in the outside air from entering the room.

[0024] 3. A dual-cooling-source fresh air dehumidification unit with an explosion-proof structure. By setting a second cooler, the air is cooled simultaneously by the first cooling group and the second cooling group, improving the indoor cooling efficiency. At the same time, the second cooler, the first radiator, the second housing, and the second radiator together form an S-shaped cavity, increasing the path of the air passing through the second cooler and lengthening the contact time between the air and the first radiator, the second radiator, and the second cooler, further improving the cooling efficiency. And a vacuum pump is connected to the exhaust hole to pump out the air inside the cavity formed by the first housing and the side plate, preventing the water vapor in the air inside the first housing from condensing on the surfaces of the first cooling group and the second cooling group and affecting the refrigeration efficiency of the first cooling group and the second cooling group.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] Embodiment: As Figure 1 、 Figure 2 and Figure 11As shown in the figure, an embodiment of the present invention provides a dual-cooling-source fresh air dehumidification unit with an explosion-proof structure, which includes a first housing 1. A top cover 2 is fixedly installed on the top of the first housing 1. A dust removal mechanism 3 is arranged at the bottom of the top cover 2. A self-circulation mechanism 4 is arranged at the bottom of the dust removal mechanism 3. An air treatment mechanism 5 is arranged at the bottom of the self-circulation mechanism 4. A heating mechanism 6 is arranged on one side of the first housing 1. The heating mechanism 6 includes a third partition 601, a second air duct 602, a first heater 603 and a second heater 604. The third partition 601 is fixedly installed on one side of the first housing 1. A second air duct 602 is communicated with one side of the third partition 601. A first heater 603 is communicated with one side of the second air duct 602. A second heater 604 is communicated with the top of the first heater 603;

[0041] As Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown in the figure, the dust removal mechanism 3 includes a first clamping plate 303, a first positioning hole 304, a limit ring 305, a first servo motor 306, an external thread block 307, an internal thread plate 308, a snap ring 309 and a clamping block 310. The first clamping plate 303 is arranged at the bottom of the top cover 2. First positioning holes 304 are respectively opened on one side of the first clamping plate 303. A limit ring 305 is fixedly installed on the top of the first clamping plate 303. A first servo motor 306 is fixedly installed on one side of the limit ring 305. An external thread block 307 is fixedly installed at the output end of the first servo motor 306. An internal thread plate 308 is threadedly sleeved on one side of the external thread block 307. A snap ring 309 is fixedly installed at the bottom of the internal thread plate 308. A clamping block 310 is movably connected to the bottom of the snap ring 309;

[0042] The dust removal mechanism 3 further includes a dust separation net 301, a first air duct 302, a filter box 311, a second clamping plate 312 and a filter sheet 313. The dust separation net 301 is fixedly installed on the top of the top cover 2. A first air duct 302 is fixedly installed at the bottom of the dust separation net 301. The filter box 311 is fixedly installed on one side of the clamping block 310. A second clamping plate 312 is fixedly installed at the bottom of the filter box 311. A filter sheet 313 is arranged inside the filter box 311.

[0043] The filter sheet 313 is composed of four groups of filter meshes. The second clamping plate 312 is fixedly installed on the top of the second gear 404. The first air duct 302 is communicated with the filter box 311.

[0044] The first clamping plate 303 is fixedly installed on the top of the filter box 311. The internal thread plate 308 is movably sleeved on one side of the output end of the first servo motor 306.

[0045] It should be further explained that when it is necessary to replace the filter cartridge 311 to clean the dust inside the filter cartridge 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 snap ring 309 at the bottom of the internal thread plate 308 to move upward at the same time, so as to disengage from the snap block 310. At this time, the filter cartridge 311 and the snap block 310 can be manually taken out between the second clamping plate 312 and the first clamping plate 303. Then, after placing the new filter cartridge 311 in the corresponding position, the first servo motor 306 is controlled to rotate counterclockwise, so as to drive the snap ring 309 to move downward and engage with the snap block 310 again. At this time, the filter cartridge 311 and the snap block 310 are fixed between the first clamping plate 303 and the second clamping plate 312, completing the fixation of the filter cartridge 311.

[0046] As Figure 6 and Figure 7 shown, the self-circulation mechanism 4 includes a first partition plate 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 rotating ring 411 and a bearing base 412. The first partition plate 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 plate 401. The output end of the second servo motor 402 is fixedly installed with the first gear 403. A second gear 404 is meshed and driven on one side of the first gear 403. Second positioning holes 405 are opened on one side of the second gear 404. A power module 406 is fixedly installed on one side of the second gear 404. The sealing tube 407 is fixedly installed at the bottom of the second positioning hole 405. The bottom of the sealing tube 407 is fixedly connected with the rotating ring 411. The bottom of the rotating ring 411 is movably installed with the bearing base 412;

[0047] The self-circulation mechanism 4 further includes a power supply piece 408, a first cooler 409, a sealing gasket 410 and a third positioning hole 413. The power supply piece 408 is fixedly installed on the top of the sealing tube 407. The bottom of the power supply piece 408 is electrically connected with the first cooler 409. A sealing gasket 410 is arranged at the bottom of the first cooler 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. The third positioning hole 413 communicates with the sealing gasket 410.

[0048] The sealing tube 407 communicates with the sealing gasket 410. The power module 406 is electrically connected with the power supply piece 408.

[0049] The sealing gasket 410 is movably connected to the top of the bearing base 412. The power supply piece 408 is arranged at the bottom of the second positioning hole 405.

[0050] It should be further explained that when the dehumidifier unit is used for a long time and water droplets condense on the heat sink of the first cooler 409, when it is necessary to clean the frozen water droplets, the second servo motor 402 is started to drive the first gear 403 to rotate clockwise, so as to drive the first gear 403 and the second gear 404 to mesh and drive. At this time, the second positioning hole 405 at the top of the second gear 404, the sealing pipe 407 at the bottom of the second gear 404, the first cooler 409 and the rotating ring 411 rotate simultaneously on the top of the bearing base 412. When the second positioning hole 405 and the first cooler 409 located directly below the first air duct 302 move from directly above the first air hole 501 to the second air hole 502 as the second gear 404 rotates, the second servo motor 402 stops, and the second gear 404 remains stationary. By starting the heater 508 and the blower connected to one side of the air blowing hole 511, the hot air heated inside the heater 508 is blown into the inside of the sealing pipe 407 through the second air hole 502. At this time, the hot air heats the heat sink on the first cooler 409, and the transpired water vapor is discharged through the second positioning hole 405. Then, the second servo motor 402 is started again to drive the second gear 404 to rotate until the sealing pipe 407 heated in the previous step moves to the top of the third air hole 503. At this time, the hot air inside the heater 508 performs a secondary heating treatment on the first cooler 409 inside the sealing pipe 407 to prevent water vapor from remaining on the heat sink of the first cooler 409. At this time, another set of sealing pipes 407 moves to directly below the first air duct 302 and communicates with the outside air as the second gear 404 rotates, without affecting the interaction of internal and external air.

[0051] As Figure 9 and Figure 10 shown, the air treatment mechanism 5 includes a first air hole 501, a second air hole 502, a third air hole 503, a fourth air hole 504, a three-way pipe 505, a first air opening 506, a second air opening 507, a heater 508, a first heating hole 509, a second heating hole 510, an air blowing hole 511 and an ultraviolet lamp 512. The first air hole 501, the second air hole 502, the third air hole 503 and the fourth air hole 504 are all opened at the top of the first partition plate 401. The bottom of the first air hole 501 is communicated with a three-way pipe 505. One side of the bottom of the three-way pipe 505 is provided with a first air opening 506, and the other side of the bottom of the three-way pipe 505 is provided with a second air opening 507. The bottom of the second air hole 502 is communicated with a first heating hole 509, and the bottom of the third air hole 503 is communicated with a second heating hole 510. The first heating hole 509 and the second heating hole 510 are both opened at the top of the heater 508. One side of the heater 508 is provided with an air blowing hole 511. The bottom of the fourth air hole 504 is communicated with an ultraviolet lamp 512, and the ultraviolet lamp 512 is fixedly installed at the bottom of the first partition plate 401.

[0052] The air handling mechanism 5 further includes a first refrigeration group 51, a second refrigeration group 52, a side plate 513, an exhaust hole 514, and a second partition plate 515. The first refrigeration group 51 and the second refrigeration group 52 are symmetrically arranged with the second partition plate 515 as the center. The second partition plate 515 is fixedly installed inside the first housing 1. A side plate 513 is fixedly installed on one side of the second partition plate 515. The exhaust hole 514 is opened on one side of the first housing 1. Both the first refrigeration group 51 and the second refrigeration group 52 include a second refrigerator 516, a first heat sink 517, a second housing 518, a second heat sink 519, and an air inlet hole 520. The second refrigerator 516 is fixedly installed on one side of the side plate 513. A first heat sink 517 is fixedly installed on one side of the second refrigerator 516. A second housing 518 is arranged on one side of the second refrigerator 516. A second heat sink 519 is fixedly installed on one side of the second housing 518. An air inlet hole 520 is opened at the top of the second housing 518.

[0053] The first heat sink 517 is arranged on one side of the second heat sink 519. 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.

[0054] The air inlet hole 520 inside the first refrigeration group 51 is communicated with the first air hole 506. The air inlet hole 520 inside the second refrigeration group 52 is communicated with the second air hole 507. The exhaust hole 514 is communicated with a vacuum pump, and the vacuum pump is arranged outside the first housing 1. The first refrigeration group 51 and the second refrigeration group 52 are communicated with the first heater 603 through a second air duct 602.

[0055] It should be further explained that when refrigeration is required inside the room, the second refrigerator 516 inside the first refrigeration group 51 and the second refrigeration group 52 is started to refrigerate the air passing through the second refrigerator 516, the first heat sink 517, and the second heat sink 519. At this time, the air advances along the S-shaped cavity curve formed by the second refrigerator 516, the first heat sink 517, the second housing 518, and the second heat sink 519, enters the inside of the S-shaped cavity through the air inlet hole 520, and after being refrigerated, enters the inside of the first heater 603 and the second heater 604 through the second air duct 602, and finally enters the inside 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, and the first refrigeration group 51 and the second refrigeration group 52 are only used as passing pipelines.

[0056] Working principle and usage process of the present invention: During the use of the present invention, when it is necessary to replace the filter cartridge 311 and clean the dust inside the filter cartridge 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 snap ring 309 at the bottom of the internal thread plate 308 to move upward simultaneously, so as to disengage from the snap block 310. At this time, the filter cartridge 311 and the snap block 310 can be manually taken out between the second clamping plate 312 and the first clamping plate 303. Then, after placing the new filter cartridge 311 at the corresponding position, the first servo motor 306 is controlled to rotate counterclockwise, so as to drive the snap ring 309 to move downward and engage with the snap block 310 again. At this time, the filter cartridge 311 and the snap block 310 are fixed between the first clamping plate 303 and the second clamping plate 312, completing the fixation of the filter cartridge 311.

[0057] 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 and drive with the second gear 404. At this time, the second positioning hole 405 at the top of the second gear 404, the sealing pipe 407 at the bottom of the second gear 404, the first cooler 409 and the rotating ring 411 rotate simultaneously on the top of the bearing base 412. When the second positioning hole 405 and the first cooler 409 located directly below the first air duct 302 move from directly above the first air vent 501 to the second air vent 502 with the rotation of the second gear 404, the second servo motor 402 stops running and the second gear 404 remains stationary. The heater 508 is started and the hot air heated inside the heater 508 is blown into the inside of the sealing pipe 407 through the second air vent 502 by the blower communicated with one side of the air blowing hole 511. At this time, the hot air heats the heat dissipation fins on the first cooler 409, and the transpired water vapor is discharged through the second positioning hole 405. Then, the second servo motor 402 is continuously started to drive the second gear 404 to rotate until the sealing pipe 407 heated in the previous step moves to the top of the third air vent 503. At this time, the hot air inside the heater 508 performs a secondary heating treatment on the first cooler 409 inside the sealing pipe 407 to avoid residual water vapor on the heat dissipation fins of the first cooler 409. At this time, the other set of sealing pipes 407 moves to directly below the first air duct 302 and communicates with the outside air with the rotation of the second gear 404, without affecting the interaction of internal and external air.

[0058] Finally, when the interior of the room needs to be cooled, connect the vacuum pump to the exhaust hole 514, start the vacuum pump to extract the air inside the sealed cavity formed by the first housing 1, the side plate 513 and the third partition 601. Then, start the second cooler 516 inside the first refrigeration group 51 and the second refrigeration group 52 to cool the air passing through the second cooler 516, the first heat sink 517 and the second heat sink 519. At this time, the air advances along the S-shaped cavity curve formed by the second cooler 516, the first heat sink 517, the second housing 518 and the second heat sink 519, enters the interior of the S-shaped cavity through the air inlet hole 520, and after being cooled, enters the interiors 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, start the heating device inside the first heater 603 and the second heater 604 to heat the air, and the first refrigeration group 51 and the second refrigeration group 52 are only used as passage pipes.
