A cleaning device 2 is arranged inside the pipe 1, and a collecting device 3 is arranged on one side of the cleaning device 2. When it is necessary to clean the dirt on the inner wall of the pipe 1, the pipe 1 is disassembled, and the cleaning device 2 is put into the pipe 1 to clean the dirt on the inner wall of the pipe 1, thereby achieving the cleaning effect.
[0029] Refer to Figures 2-3, the cleaning device 2 includes a round block 22 arranged inside the pipeline 1. A hollow rod 24 is fixedly connected to the side surface of the round block 22. A slide rod is slidably connected inside the hollow rod 24. One end of the slide rod is fixedly connected to a brush plate 23. A magnetic ring 21 is slidably connected to the surface of the pipeline 1. A magnetic plate is fixedly connected to the upper top of the brush plate 23. Under the action of the magnetic ring 21, the magnetic plate can move inside the pipeline 1 following the magnetic ring 21. Thus, the dirt on the inner wall of the pipeline 1 can be cleaned by the brush plate 23. When it is necessary to clean the dirt on the inner wall of the pipeline 1, the pipeline 1 is disassembled, and the cleaning device 2 is put into the pipeline 1 to clean the dirt on the inner wall of the pipeline 1, thereby achieving the cleaning effect. A brush 25 is arranged on the side surface of the brush plate 23. Elastic ropes 26 are fixedly connected to the side surface of the brush 25. The two ends of the elastic ropes 26 are respectively fixedly connected to the side surface of the brush 25. Under the action of the elastic ropes 26, the brush 25 can be pulled out from the inside of the brush plate 23. Thus, the entire inner wall of the pipeline 1 is closely attached to the brush 25 and the brush plate 23, and then the cleaning is completed. A spring 28 is fixedly connected inside the hollow rod 24. The other end of the spring 28 is fixedly connected to one end of the slide rod. Under the action of the spring 28, the brush plate 23 can be closely attached to the inner wall of the pipeline 1, which is convenient for cleaning the dirt. A circular groove is formed in the inner wall of the magnetic ring 21. A ball 27 is rotatably connected inside the circular groove. Under the action of the ball 27, the frictional force between the magnetic ring 21 and the surface of the pipeline 1 is reduced, which is convenient for moving the magnetic ring 21. One end of the slide rod and one end of the hollow rod 24 are conveniently fixedly connected with a baffle 29. Under the action of the baffle 29, the slide rod will not completely extend out of the inside of the hollow rod 24, thus avoiding the separation of the slide rod from the hollow rod 24. When cleaning the pipeline 1, the pipeline 1 is disassembled, and the round block 22 is inserted into the pipeline 1. Under the action of the spring 28, the slide rod extends out of the inside of the hollow rod 24. Under the action of the baffle 29, the slide rod will not completely extend out of the inside of the hollow rod 24, thus avoiding the separation of the slide rod from the hollow rod 24. The brush plate 23 is closely attached to the inside of the pipeline 1. Under the action of the elastic ropes 26, the brush 25 can be pulled out from the inside of the brush plate 23. Thus, the entire inner wall of the pipeline 1 is closely attached to the brush 25 and the brush plate 23, and then the cleaning is completed. The magnetic ring 21 is sleeved on the outer surface of the pipeline 1. In cooperation with the magnetic plate, the brush plate 23 moves inside the pipeline 1. Under the action of the ball 27, the frictional force between the magnetic ring 21 and the surface of the pipeline 1 is reduced, which is convenient for moving the magnetic ring 21, thereby achieving the cleaning effect.

A filter frame 33 is fixedly connected to the inner wall of the collection frame 32. The filter frame 33 covers the air suction port of the suction fan 34. Under the action of the filter frame 33, the dirt will not block the air suction port of the suction fan 34. A clamping strip 35 is fixedly connected to the surface of the collection frame 32. An annular groove 36 is formed at the bottom of the round plate 31. A clamping groove and a clamping ring are formed inside the annular groove 36. A round groove is formed on the surface of the collection frame 32. The clamping ring is in interference fit with the round groove. With the cooperation of the clamping ring and the round groove and the cooperation of the clamping strip 35 and the clamping groove, the collection frame 32 can be fixed to the round plate 31, and at the same time, it is also convenient for disassembly. When cleaning the inner wall of the pipeline 1, the collection frame 32 is fixed to the round plate 31 through the cooperation of the clamping ring and the round groove and the cooperation of the clamping strip 35 and the clamping groove. The suction fan 34 is started, so that the dirt cleaned is sucked into the interior of the collection frame 32 through the through grooves. Under the action of the filter frame 33, the dirt will not block the air suction port of the suction fan 34, thus achieving the collection function.
[0031] Working principle: When the special descaling device for the HVAC pipeline 1 is needed, when the inner wall of the pipeline 1 needs to be cleaned of dirt, the pipeline 1 is disassembled, and the cleaning device 2 is put into the interior of the pipeline 1 to clean the dirt on the inner wall of the pipeline 1, thus achieving the cleaning function. When cleaning the pipeline 1, the pipeline 1 is disassembled, and the round block 22 is inserted into the interior of the pipeline 1. Under the action of the spring 28, the sliding rod extends out of the interior of the hollow rod 24. Under the action of the baffle 29, the sliding rod will not completely extend out of the interior of the hollow rod 24, thus avoiding the separation of the sliding rod from the hollow rod 24 and making the brush plate 23 closely adhere to the interior of the pipeline 1. Under the action of the elastic cord 26, the brush 25 can be pulled out from the interior of the brush plate 23, so that the entire inner wall of the pipeline 1 is closely attached to the brush 25 and the brush plate 23, thus completing the cleaning. The magnetic ring 21 is sleeved on the outer surface of the pipeline 1. With the cooperation of the magnetic plate, the brush plate 23 moves inside the pipeline 1. Under the action of the ball 27, the frictional force between the magnetic ring 21 and the surface of the pipeline 1 is reduced, thus facilitating the movement of the magnetic ring 21, and thus achieving the cleaning function. When cleaning the inner wall of the pipeline 1, the collection frame 32 is fixed to the round plate 31 through the cooperation of the clamping ring and the round groove and the cooperation of the clamping strip 35 and the clamping groove. The suction fan 34 is started, so that the dirt cleaned is sucked into the interior of the collection frame 32 through the through grooves. Under the action of the filter frame 33, the dirt will not block the air suction port of the suction fan 34, thus achieving the collection function.
