Description

Technical Field

[0001] The utility model relates to the technical field of air conditioner maintenance, in particular to a filter screen cleaning device for air conditioner maintenance. Background Technique

[0002] The air conditioner filter screen is arranged at the air inlet of the air conditioner indoor unit and is used to filter particulate matters such as dust in the air, so that the air conditioner can blow out clean air. In order to ensure the filtering effect, the pore diameter of the mesh on the air conditioner filter screen is relatively small to ensure that tiny dust in the air can be filtered out. After the air conditioner is used for a long time, a large amount of dust will adhere to the surface or pores of the air conditioner filter screen, and it needs to be cleaned regularly.

[0003] After retrieval, the Chinese patent publication number is CN218608456U, which discloses a filter screen cleaning device for central air conditioner maintenance.

[0024] The present utility model will be further described below in conjunction with the accompanying drawings:

[0025] As Figures 1 - 5 shown, a filter screen cleaning device for air conditioner maintenance includes a water tank 1. A plurality of support bars 2 are inserted between the inner walls of the water tank 1. U-shaped notches are provided at the ends of the support bars 2 to facilitate clamping and fixing of the filter screen. A water inlet pipe 101 and a water outlet pipe 102 are welded to one side of the water tank 1, and the water outlet pipe 102 is located at the bottom of the water tank 1.

[0026] A cleaning mechanism is provided at the top of the water tank 1. The cleaning mechanism includes a mounting frame 301 bolted to the top of the water tank 1. A rotary motor 302 is bolted to one side of the mounting frame 301. The output end of the rotary motor 302 is connected to a lead screw 303 through a coupling. The lead screw 303 is rotatably connected between the inner walls of the mounting frame 301. A slider 304 is threadedly connected to the lead screw 303. The slider 304 is slidably connected to the inner top wall of the mounting frame 301. The bottom of the slider 304 is fixedly connected to an electric push rod 305. The bottom of the electric push rod 305 is fixedly connected to a U-shaped support frame 306. A brush plate 307 is arranged between the support frames 306. The bottom of the brush plate 307 is fixedly connected to bristles 308. The bristles 308 pass through the support frame 306. The bristles 308 are movably connected to the support frame 306. By controlling the electric push rod 305, the support frame 306 drives the bristles 308 to move downward, so that the bristles 308 are in contact with the filter screen. The rotary motor 302 is started. The rotary motor 302 drives the lead screw 303 to rotate. The lead screw 303 drives the slider 304 to move. The slider 304 drives the bristles 308 to move back and forth to clean the filter screen.

[0027] A sealing box 4 is bolted to the inner bottom wall of the support frame 306. The brush plate 307 is slidably connected between the inner walls of the sealing box 4. The brush plate 307 divides the interior of the sealing box 4 into an upper chamber and a lower chamber. A connecting pipe 6 is connected to the rear side of the sealing box 4. The connecting pipe 6 extends to the bottom of the water tank 1. A check valve is arranged in the connecting pipe 6. Water can only enter the sealing box 4 through the connecting pipe 6, but cannot flow out through the connecting pipe 6. The connecting pipe 6 is an elastic hose. The connecting pipe 6 is communicated with the lower chamber of the sealing box 4. A water flow hole is opened at the bottom of the support frame 306. The water flow hole is a conical shape with a small opening facing downward, which is convenient for accelerating the water flow and improving the flushing effect. A shielding component is arranged at the bottom of the support frame 306 below the water flow hole. A power component is arranged on the support frame 306. The power component is used to drive the brush plate 307 to move up and down.

[0028] The power component includes a hydraulic cylinder 5. The hydraulic cylinder 5 is fixedly connected to the inner top wall of the support frame 306. The bottom of the hydraulic cylinder 5 is fixedly connected to the brush plate 307.

[0029] The shielding component includes a rotating shaft 7 fixedly connected to the bottom of the support frame 306. A baffle 8 is rotatably connected to the rotating shaft 7. The baffle 8 is located below the water flow hole. A torsion spring is arranged between the baffle 8 and the rotating shaft 7. When the brush plate 307 moves downward, the water in the lower chamber of the sealing box 4 presses the baffle 8 to open the water flow hole. After the water is discharged, the baffle 8 resets under the action of the torsion spring.

[0030] Working principle: When in use, place the filter screen between the support bars 2. Control the electric push rod 305 to drive the support frame 306 to drive the brush plate 307 and the bristles 308 to move downward, so that the bristles 308 are in contact with the filter screen. Start the rotary motor 302, and the rotary motor 302 drives the lead screw 303 to rotate. The lead screw 303 drives the slider 304 to move, and the slider 304 drives the electric push rod 305, the support frame 306, the brush plate 307, and the bristles 308 to move back and forth to clean the filter screen. When it is necessary to clean the impurities in the bristles 308, drive the brush plate 307 to drive the bristles 308 to move upward through the hydraulic cylinder 5. The flocs and impurities at the root of the bristles 308 are pushed to the ends of the bristles 308 through the blocking action of the support frame 306. When the brush plate 307 moves upward, the water in the water tank 1 will be pumped into the lower cavity of the sealed box 4 through the connecting pipe 6. When the hydraulic cylinder 5 drives the brush plate 307 to drive the bristles 308 to move downward, the brush plate 307 accelerates and squeezes out the water in the lower cavity of the sealed box 4 through the water flow holes. The water flow is sprayed toward the bristles 308 under the guidance of the baffle 8, so as to wash away the flocs at the ends of the bristles 308 and ensure the cleaning effect of the bristles 308.

[0031] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
