[0020] A sleeve 8 is fixedly installed on the front side of the housing 1, a piston 7 is sealed and slidably installed in the sleeve 8, and a connecting plate 6 is fixedly installed on the outside of the piston 7. A shunting groove is opened along the length direction of the front side of the housing 1, the shunting groove is connected with the inside of the installation cavity, the connecting plate 6 passes through the shunting groove and is fixedly installed with one of the movable plates 4, and the connecting plate 6 is slidably installed with the shunting groove. A first flow pipe 10 connected with the inside of the sleeve 8 is installed on the top of the sleeve 8, and a first one-way valve 9 is installed on the first flow pipe 10. The first one-way valve 9 controls the flow direction of the liquid to flow from the sleeve 8 into the first flow pipe 10.

[0021] A cleaning assembly for cleaning the pipe is installed at the end of the first flow pipe 10. The cleaning assembly includes a cleaning ring 11 and a plurality of high-pressure nozzles 12. The cleaning ring 11 is fixedly sleeved at the end of the first flow pipe 10. The cleaning ring 11 is composed of a fixed ring and a cleaning sponge. The fixed ring is fixedly sleeved at the end of the first flow pipe 10. The cleaning sponge is fixedly sleeved on the outer peripheral surface of the fixed ring. The cleaning sponge cleans the inside of the air conditioning pipe. A plurality of high-pressure nozzles 12 are installed at the end of the first flow pipe 10.

[0022] The center point of the cleaning ring 11 and the center point of the fixing ring 5 are located on the same horizontal line, ensuring that the cleaning ring 11 can be accurately inserted into the interior of the air conditioning duct.

[0023] A water tank 15 is fixedly installed on the right side of the box body 1. The water tank 15 is connected to the interior of the sleeve 8 through the second flow pipe 13. A second one-way valve 14 is installed on the second flow pipe 13. The second one-way valve 14 controls the flow direction of the liquid from the water tank 15 into the sleeve 8.

[0024] The working principle of the air conditioning pipeline cleaning device provided by the utility model is as follows:

[0025] In the initial state, the right side of the piston 7 is in contact with the wall of the sleeve 8 .

[0026] When in use, start the motor 2, the motor 2 drives the screw rod 3 to rotate, the screw rod 3 drives the movable plate 4 to move to the left, and the movable plate 4 drives the piston 7 to move to the left through the connecting plate 6, thereby generating negative pressure inside the sleeve 8. Due to the action of the first one-way valve 9, the liquid cannot flow from the first flow pipe 10 into the sleeve 8. Therefore, suction is generated inside the sleeve 8, and the water in the water tank 15 can be sucked into the sleeve 8 through the second flow pipe 13 and the second one-way valve 14.

[0027] At this time, insert the pipe to be cleaned into the two fixing rings 5, and fix the pipe by clamping the rubber ball to keep it stable, and put the end of the pipe on the cleaning ring 11, and the cleaning sponge on the outer periphery of the cleaning ring 11 fits the inner wall of the pipe. Then start the motor 2 again, so that the output end of the motor 2 rotates in the opposite direction, the motor 2 drives the screw rod 3 to rotate, the screw rod 3 drives the two moving plates 4 to move rightward, the two moving plates 4 respectively drive the corresponding fixing rings 5 ​​to move rightward, and the fixing ring 5 drives the air conditioning pipe to move rightward, so that the cleaning ring 11 cleans the inside of the air conditioning pipe.

[0028] When the movable plate 4 moves to the right, it drives the connecting plate 6 to move to the right, and the connecting plate 6 drives the piston 7 to move to the right. Due to the action of the second one-way valve 14, the liquid cannot flow from the sleeve 6 into the water tank 15. Therefore, the piston 7 moves to the right and squeezes the water in the sleeve 8 into the first flow pipe 10 through the first one-way valve 9, and finally sprays into the air-conditioning pipe from multiple high-pressure nozzles 12 to clean the air-conditioning pipe, and cooperates with the cleaning ring 11 to clean the inner wall of the air-conditioning pipe, so that the cleaning is more thorough, the operation steps are simple, and the cleaning efficiency is improved.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
