DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] The utility model discloses a filter structure for a dehumidifier, such as Figure 1-5 As shown, it includes a flow pipe 1 fixed on the air inlet pipe of the dehumidifier. A filter block 2 is provided in the flow pipe 1 for filtering the air entering the dehumidifier to filter dust and impurities in the air.

[0022] Two rotating shafts 102 are movably installed inside the circulation tube 1, and a sealing plate 103 is fixedly installed on one side of the two rotating shafts 102 located inside the circulation tube 1. When the rotating shafts 102 rotate, they can drive the sealing plate 103 to rotate to achieve blocking of the circulation tube 1.

[0023] Gears 101 are fixedly mounted on one end of the two rotating shafts 102 extending to the outside of the circulation tube 1. When the gears 101 rotate, the rotating shafts 102 can be driven to rotate.

[0024] A threaded rod 104 is movably mounted on one side of the outer top surface of the circulation tube 1, and a sliding rod 105 is fixedly mounted on the other side of the outer top surface of the circulation tube 1. A connecting rod 106 is threadedly connected to the outer surface of the threaded rod 104, and the connecting rod 106 is movably connected to the sliding rod 105. When the threaded rod 104 is rotated, the connecting rod 106 can be moved, and the sliding rod 105 can guide the connecting rod 106. A rubber turning handle is fixedly mounted on one end of the threaded rod 104.

[0025] Racks 107 are fixedly installed at both ends of the connecting rod 106, and the two racks 107 are respectively engaged with the two gears 101. When the connecting rod 106 moves with the rotation of the threaded rod 104, it can drive the two racks 107 to move, and then the two racks 107 can drive the two gears 101 to rotate, so that the two sealing plates 103 can rotate at the same time.

[0026] The two sealing plates 103 are both provided with a collection box 1032 on one side of the filter block 2. An insert block 1033 is fixedly installed on one side of the outer surface of the collection box 1032, and springs 1034 are fixedly installed on both sides of the outer surface of the insert block 1033. A slot 1031 is provided on one side of the outer surface of the sealing plate 103. The spring 1034 has a certain spring. When the insert block 1033 is inserted into the slot 1031, the collection box 1032 can be installed. When cleaning the dust and impurities on the mesh surface of the filter 207, the dust on the mesh surface close to the sealing plate 103 will fall into the collection box 1032, so as to prevent the dust and impurities on the mesh surface from falling into the dehumidifier when cleaning the filter 207.

[0027] The filter block 2 includes a mounting frame 201 and a filter screen 207. Four support plates 202 are fixedly installed inside the mounting frame 201, and a magnet 203 is fixedly installed on one side of the four support plates 202. Shrinkage holes 204 are provided on both sides of the outer surface of the mounting frame 201, and first springs 205 are fixedly installed inside the two shrinkage holes 204. One end of the two first springs 205 is fixedly installed with a limit block 206. Limiting holes are provided on both sides of the outer surface of the circulation tube 1, and the sizes of the two limit holes are the same as the sizes of the two limit blocks 206. When the mounting frame 201 is placed in the circulation tube 1, during the placement process, the limit block 206 will shrink into the shrinkage hole 204 and squeeze the first spring 205. When the mounting frame 201 continues to move to the limiting hole, the squeezed first spring 205 can pop out the limit block 206, so that the limit block 206 is inserted into the limiting hole to complete the connection of the mounting frame 201.

[0028] Four iron sheets 208 are fixedly mounted on one side of the filter 207 . The iron sheets 208 are adsorbed by the magnets 203 to complete the installation of the filter 207 .

[0029] Two movable grooves 301 are provided on one side of the outer surface of the circulation tube 1 , and guide rods 302 are fixedly installed inside the two movable grooves 301 , and the outer surfaces of the two guide rods 302 are movably connected to brush plates 304 , which can be raised and lowered along the guide rods 302 .

[0030] The inner bottom surfaces of the two movable grooves 301 are fixedly mounted with second springs 303 , and the two second springs 303 are fixedly connected to the brush plate 304 . When the brush plate 304 descends, it can squeeze the second springs 303 .

[0031] A driving frame 305 is fixedly installed on one side of the brush plate 304, a micro motor 306 is fixedly installed on the outer bottom surface of the circulation tube 1, and an eccentric wheel 307 is fixedly installed on the output end of the micro motor 306. The eccentric wheel 307 is in contact with the driving frame 305. When the micro motor 306 drives the eccentric wheel 307 to rotate, the driving frame 305 and the brush plate 304 can be raised and lowered to clean the dust and impurities on the filter 207.

[0032] The working principle of the present invention is as follows: by rotating the threaded rod 104, the connecting rod 106 can drive the two racks 107 to move, and the two moving racks 107 can drive the two gears 101 to rotate in opposite directions. When the gear 101 rotates, it can drive the sealing plate 103 to flip over to seal the circulation pipe 1, and then the micro motor 306 can be started to drive the eccentric wheel 307 to rotate, so that the drive frame 305 and the brush plate 304 can be raised and lowered to clean the dust and impurities on the filter 207. The dust that falls during cleaning will fall into the collection box 1032, which can effectively prevent the dust and impurities on the mesh surface of the filter 207 from falling into the inside of the dehumidifier when cleaning, thereby affecting the air quality after dehumidification.
