[0019] The present invention will be further described below with reference to the accompanying drawings and examples.

[0020] like Figure 1 As shown, this embodiment discloses a cleaning device for an air-conditioning fan of an electrical cabinet, comprising an opening 3 provided on the top of the electrical cabinet 1 , the opening 3 being located above and in front of the air-conditioning fan surface in the electrical cabinet 1 .

[0021] like Figure 3 As shown, a fixed cylinder 16 is provided at the top of the electrical cabinet 1 behind the opening 3. The bottom of the fixed cylinder 16 is fixed to the top of the electrical cabinet 1. An opening is provided on the front side of the fixed cylinder 16. An axially vertical screw rod 17 is provided in the fixed cylinder. The screw rod 17 is rotatably installed between the top and bottom of the fixed cylinder 16. A slider is also provided in the fixed cylinder 16. The shape of the slider matches the horizontal cross-sectional shape of the fixed cylinder 16. The slider is screwed to the screw rod 17 through a threaded through hole. The upper end of the screw rod 17 passes through the top of the fixed cylinder 16, and the upper end of the screw rod 17 is fixedly connected to a rotary handle. The inside of the fixed cylinder 16 serves as a guide groove for the vertical sliding of the slider. When the rotary handle is rotated, the screw rod 17 rotates, causing the slider to move vertically up and down in the fixed cylinder 16. The screw-slider mechanism of the fixed cylinder 16, the screw rod 17, and the slider is used as a lifting drive mechanism.

[0022] A cantilever 18 is provided in front of the fixed cylinder 16 in the lift drive mechanism. The rear end of the cantilever 18 extends through an opening in the front of the fixed cylinder 16 and is fixedly connected to the slider. The front end of the cantilever 18 is fixedly connected to the first adjustment plate 2, which is located above the opening 3 in the top of the electrical cabinet 1. When the slider of the lift drive mechanism moves up and down, the cantilever 18 and the first adjustment plate 2 can be lifted and lowered as a whole.

[0023] like Figure 2 、 Figure 5 As shown, the first adjustment plate 2 is provided with a sliding hole 20 extending in the front-to-back direction. The sliding hole 20 vertically penetrates the first adjustment plate 2. A movable block 19 is mounted in the sliding hole 20 for horizontal sliding movement. The upper portion of the movable block 19 extends upward through the sliding hole 20, while the lower portion of the movable block 19 extends downward through the sliding hole 20. Guide plates are connected to the front and rear sides of the movable block 19 located within the sliding hole 20. Guide grooves 24 are provided in the front and rear walls of the sliding hole 20, respectively. The guide plates on the front and rear sides of the movable block 19 slide and fit into the guide grooves 24 in the front and rear walls of the sliding hole 20, respectively.

[0024] A positioning plate 21 is fixed on the top of the first adjustment plate 2 in front of the sliding hole 20 , and an axially horizontal adjustment screw 22 is screwed through the upper part of the movable block 19 , and the adjustment screw 22 is screwed through the threaded through hole of the positioning plate 21 .

[0025] When the adjusting screw 20 is rotated, the movable block 19 can move back and forth within the sliding hole 20. The guide groove 24 within the sliding hole 20 cooperates with the guide plate of the movable block 19 to support and guide the forward and backward movement of the movable block 19. A docking seat 6 is provided below the first adjusting plate 2. The top of the docking seat 6 is fixed to the bottom of the movable block 19. The front side of the docking seat 6 is fixedly connected to a forward-extending clamping block 8. The front end of the clamping block 8 is configured as a downwardly curved hook portion.

[0026] A brush holder 7 is also provided between the first adjustment plate 2 and the opening 3. A docking seat 6 is located behind the upper end of the brush holder 7, with the front side of the docking seat 6 facing the rear side of the upper end of the brush holder 7. Bristles 5 are provided on the rear side of the brush holder 7, below the docking seat 6, to form a brush surface. The bristles 5 are flexible, soft bristles. The lower end of the brush holder 7 is fixedly connected to a second adjustment plate 4, which is inserted into the opening 3 at the top of the electrical cabinet 1. A sealing layer 23 is provided at the bottom of the second adjustment plate 4 to form a seal with the opening 3. The rear ends of the bristles 5 on the rear side of the brush holder 7 extend backward, extending beyond the rear edge of the second adjustment plate 4.

[0027] like Figure 4 、 Figure 5 As shown, a card slot 11 is provided on the rear side of the upper end of the brush seat 7, and the card block 8 connected to the front side of the docking seat 6 extends forward and is inserted into the card slot 11 on the rear side of the upper end of the brush seat 7. A mounting slot 12 is provided in the brush seat 7 below the card slot 11. The front side of the mounting slot 12 is open on the front side of the brush seat 7 to form a notch. The mounting slot 12 and the card slot 11 are connected by a vertical slide provided in the brush seat 7.

[0028] An L-shaped positioning block 9 is provided within the mounting slot 12. The horizontal portion of the positioning block 9 is located within the mounting slot 12, and the vertical portion of the positioning block 9 passes upward through the vertical slideway and into the clamping slot 11. The vertical portion of the positioning block 9 is engaged with the hook portion of the clamping block 8, thereby limiting and securing the clamping block 8 within the clamping slot 11. Several vertical springs 10 are connected between the horizontal portion of the positioning block 9 located within the mounting slot 12 and the bottom of the mounting slot 12. A pull post 13 is also connected to the horizontal portion of the positioning block 9, which extends forward into the notch of the mounting slot 12.

[0029] The movable connection structure is composed of a clamping block 8, a clamping slot 11, a mounting slot 12, a positioning block 9, a spring 10, and a pulling post 13. This movable connection structure is used to flexibly connect the docking seat 6 and the upper end of the brush holder 7. When the positioning block 9 limits and fixes the clamping block 8, the docking seat 6 is fixed to the rear side of the upper end of the brush holder 7. When the pulling post 13 is pulled downward until the vertical portion of the positioning block 9 disengages the hook portion of the clamping block 8, the clamping block 8 is released, that is, the fixation between the docking seat 6 and the brush holder 7 is released. The brush holder can then be moved downward to disassemble the brush holder 7. When the pulling post 13 is released, the positioning block 9 is reset under the action of the spring 10.

[0030] A hook 15 is fixed to the bottom of the slot of the mounting slot 12, and a hanging ring 14 is connected to the inner portion of the pulling column 13 located in the slot of the mounting slot 12. After pulling the pulling column 13 downwards, the hanging ring 14 can be hung on the hook 15, thereby keeping the positioning block 9 in the posture after being pulled downwards.

[0031] In this embodiment, when the fan is cleaned, the cantilever 18 and the first adjustment plate 2 are driven to descend as a whole through the lifting drive mechanism, thereby causing the docking seat 6 and the brush seat 7 to descend as a whole, wherein the brush seat 7 descends to enter the electrical cabinet 1 from the opening 3 at the top of the electrical cabinet 1. Since the second adjustment plate 4 itself is blocked in the opening 3, the second adjustment plate 4 can smoothly pass through the opening 3 into the electrical cabinet 1. Although the bristles 5 on the rear side of the brush seat 7 extend backward beyond the rear side of the second adjustment plate 4, since the bristles 5 are soft, the bristles 5 can also smoothly pass through the opening 3 into the electrical cabinet 1 after being squeezed.

[0032] When the brush holder 7 enters the electrical cabinet 1, the bristles 5 on the rear side of the brush holder 7 come into contact with the fan surface of the air conditioner in the electrical cabinet, and the fan surface can be cleaned while the fan is in operation. After cleaning, the lifting drive mechanism is reset and the brush holder 7 can be removed from the electrical cabinet 1, so that the operation of the fan will not be disturbed after cleaning.

[0033] When the bristles 5 on the brush holder 7 need to be free of dust, the lifting drive mechanism can be used to drive the cantilever 18 to rise until the second adjustment plate 4 is upwardly disengaged from the opening 3 on the top of the electrical cabinet 1. Then, the pulling column 13 is pulled downward to release the fixation of the docking seat 6 and the brush holder 7, and the brush holder 7 can be easily removed.

[0034] When a new or cleaned brush holder 7 needs to be reassembled, the pulling column 13 is pulled downward again to connect the docking seat 6 with the brush holder 7, and then the pulling column 13 is released to fix the brush holder 7 and the docking seat 6 again.
