Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0023] Example: See Figure 1-4A duct filter cleaning device for an air conditioner comprises a base 1, a cleaning box 2 is fixedly connected to the top of the base 1, a cleaning frame 3 is arranged in the inner cavity of the cleaning box 2, a notch 4 is opened at the top of the base 1, a water spray mechanism 5 is arranged at the top of the inner cavity of the cleaning box 2, fastening grooves 6 are opened at both ends of the inner cavity of the cleaning frame 3, a fastening block 7 is arranged in the inner cavity of the fastening groove 6, a motor 8 is fixedly connected to the back of the front fastening block 7, a rolling brush 9 is arranged between the relative fastening blocks 7, a sliding rod 10 is fixedly connected to the inner cavity of the fastening groove 6, a spring 11 is arranged on the outer ring of the sliding rod 10, a driving mechanism 12 is arranged on the inner wall of the cleaning box 2, a sealing door 13 is arranged at one end of the cleaning box 2, and limit bolts 14 are arranged through both ends of the cleaning box 2, and a limit block 15 is fixed at one end of the limit bolt 14.

[0024] Furthermore, the roller brush 9 is fixed on the output shaft of the motor 8, and the fastening block 7 is slidably connected to the slide rod 10. The filter is inserted into the cleaning box 2 from the slot 4, passing through between the two roller brushes 9 during the process. Under the action of the spring 11 on the outer ring of the slide rod 10 and the fastening block 7, the roller brush 9 is squeezed into contact with the filter according to the thickness of the filter to ensure the filter cleaning effect.

[0025] Furthermore, the water spraying mechanism 5 is composed of a U-shaped tube 501 and a water inlet pipe 502. The U-shaped tube 501 is arranged at the bottom of the outer circle of the groove 4. The outer circle of the U-shaped tube 501 is provided with a nozzle facing the inside of the cleaning box 2. The water inlet pipe 502 is arranged at one end of the U-shaped tube 501. When the water spraying mechanism 5 is used to spray water, the water pipe is directly connected to the water inlet pipe 502, and water is injected into the U-shaped tube 501. Finally, the water is sprayed toward both sides of the filter by the nozzle facing the inside of the cleaning box 2. The water is sprayed in a directional manner, which saves water resources while ensuring that the water can be sprayed directly on the filter, thereby ensuring the effect of cleaning the filter using the roller brush 9 later.

[0026] Furthermore, the driving mechanism 12 consists of a moving groove 121, a moving seat 122, a screw 123 and a servo motor 124. The moving groove 121 is opened on the inner cavity wall at one end of the cleaning box 2. The inner cavity of the moving groove 121 is provided with a moving seat 122, and the moving seat 122 is fixedly connected to the cleaning frame 3.

[0027] Furthermore, the inner cavity of the movable groove 121 is provided with a screw 123, and the screw 123 and the movable seat 122 are threadedly connected. A servo motor 124 is fixedly connected to the top of the cleaning box 2, and the output shaft of the servo motor 124 is fixedly connected to the screw 123. When the filter is placed between the two roller brushes 9 in the cleaning frame 3, the servo motor 124 is opened to drive the screw 123 to rotate, and then under the action of the movable seat 122 in the movable groove 121, the cleaning frame 3 is driven to move up and down, and then the filter is comprehensively cleaned up and down on both sides to ensure the cleaning effect of the filter.

[0028] Furthermore, a drainage groove 16 is provided at the bottom of the cleaning box 2, the interior of the base 1 is hollow and a drainage pipe 17 is provided at one end. The sewage generated by cleaning will flow into the interior of the base 1 from the drainage groove 16. When the sewage is full, it can be discharged through the drainage pipe 17 for post-processing or secondary utilization, thereby improving the utilization rate of water resources.

[0029] Furthermore, a heating device 20 is provided on the top of the cleaning box 2, and a connecting pipe 18 is provided at one end of the heating device 20. The connecting pipe 18 and the outer circle of the water inlet pipe 502 are both provided with valves 19. After the filter is cleaned, the valve 19 on the water inlet pipe can be closed, and the valve 19 on the connecting pipe 18 can be opened. Then, the heating device 20 is turned on to heat the air and then introduce it into the U-shaped tube 501 from the connecting pipe 18, so that the cleaned filter and the internal structure in the cleaning box 2 can be blown and dried, thereby improving the functionality while avoiding corrosion damage to the structural parts caused by the high humidity inside the device.

[0030] Working principle: When using this air duct filter cleaning device for air conditioners, the filter is inserted into the cleaning box 2 from the slot 4, passing through the two roller brushes 9 during the process, and under the action of the spring 11 on the outer ring of the slide rod 10 and the fastening block 7, the roller brush 9 is squeezed and contacted with the filter according to its thickness. When the motor 8 is turned on to drive the roller brush to rotate, the driving mechanism 12 is used to drive the cleaning frame 3 to move up and down, and the water spraying mechanism 5 is used to carry out directional water spraying to clean the filter, which solves the problem that the existing air duct filter cleaning device is difficult to quickly clean the filter; when the filter is placed into the cleaning box 2 from the slot 4, when the filter reaches the bottom of the cleaning box 2, the limit bolt 14 can be rotated to drive the limit block 15 to move to the middle until it contacts with both ends of the filter, and then the bottom of the filter is fixed to ensure that the cleaning frame 3 is more stable when moving up and down to clean the filter.
