DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-5As shown, the utility model is a convenient central air conditioner fin cleaning device, comprising a handle 1, and a switch button 11 is arranged on the surface of the handle 1. A square limit groove 12 is arranged on the top of the handle 1, and the limit groove 12 is located at the central axis position of the handle 1. An adjusting motor 13 is arranged at the bottom of the limit groove 12, and the output end of the adjusting motor 13 is arranged vertically upward, and the output end of the adjusting motor 13 is coaxially fixedly connected with a transmission screw 14. A moving block 15 is slidably connected inside the limit groove 12, and a slot is arranged at the bottom of the moving block 15, and the inner wall of the slot of the moving block 15 is threadedly connected with the transmission screw 14. A fixed structure 2 is fixedly arranged on the top of the moving block 15, and a connecting plate 21 of the fixed structure 2 is fixedly connected to the top of the moving block 15. Two installation cavities 22 are arranged inside the connecting plate 21, and the two installation cavities 22 are symmetrically arranged about the central plane of the connecting plate 21. Openings are arranged on both sides of the installation cavity 22, and the installation cavity 22 is connected to the outside of both sides of the installation plate 41 through the openings. The two openings of each installation cavity 22 are slidably provided with metal rods 23, and the same end of the two metal rods 23 is provided with a top plate 24, and the same connecting rod 25 is fixedly connected between the top plates 24 on both sides. The circumferential surface of the metal rod 23 located in the installation cavity 22 is provided with a mounting ring 26, and the mounting ring 26 and the installation cavity 22 near the top plate 24 are provided with a return spring 27. The side of the connecting plate 21 away from the connecting rod 25 is rotatably connected with the rotating plate 3, and the side of the rotating plate 3 near the connecting plate 21 is provided with a circular sliding groove 31, and a circle of electromagnets 32 is provided at the bottom of the sliding groove 31. One end of the metal rod 23 extends into the bottom of the sliding groove 31.

[0029] A cleaning housing is fixedly provided on one side of the rotating plate 3 away from the connecting plate 21, a mounting plate 41 is provided in the inner cavity of the cleaning housing, a driving motor 42 is provided on the mounting plate 41, and an output terminal of the driving motor 42 extends out of the cleaning housing. A rotating disk 43 is fixedly provided at the output end of the driving motor 42, and bristles are provided on one side of the rotating disk 43.

[0030] The regulating motor 13 , the driving motor 42 , the electromagnet 32 ​​and the switch button 11 are electrically connected; the output shaft of the driving motor 42 is located on the central axis connected to the rotating disk 43 .

[0031] When using this convenient central air conditioner fin cleaning device, the drive motor 42 inside the cleaning housing is controlled by the switch button 11 to work, and the output end of the drive motor 42 drives the rotating disk 43 to rotate so that the brush contacts the air conditioner fin for cleaning. When the cleaning position is too high, the adjustment motor 13 inside the handle 1 is electrically controlled by the switch button 11 to work, driving the transmission screw 14 to rotate, and the moving block 15 outside the transmission screw 14 is subjected to the thread force and the limiting effect of the limiting groove 12 to move in the vertical direction, thereby changing the distance between the top connecting plate 21 and the handle 1. The rotating disk 43 is driven to move, so that a higher position can be cleaned. During the operation of the rotating disk 43, the electromagnet 32 ​​always keeps working to absorb the metal rod 23 for fixing. When a dead corner that is difficult to contact is touched during the cleaning process, the electromagnet 32 ​​is electrically controlled by the switch button 11 to stop working. At this time, the reset spring 27 drives the metal rod 23 to disengage from the electromagnet 32 ​​through the mounting ring 26, thereby releasing the fixation between the connecting plate 21 and the rotating plate 3. Then, the rotating plate 3 is rotated to adjust the angle of the rotating disk 43 to rotate it to a position convenient for cleaning, and the electromagnet 32 ​​is started again by the switch button 11. The electromagnet 32 ​​absorbs the two metal rods 23 inside the installation cavity 22 for contact and fixation.
