Among them, during the long-term use of the ventilation ducts, dust and impurities will adhere to the inner walls of the ducts. When cleaning the dust inside the ducts, the existing technology generally disassembles the ducts and then rinses them with water. First, disassembling the ducts for cleaning requires manpower to disassemble and install the ducts, which requires a large amount of manpower. After the ducts are disassembled, the blowers or exhaust fans used to deliver air to the ducts need to stop working, resulting in affecting the air purification indoors and outdoors of the building during the cleaning process.

[0012] Furthermore, a plurality of mounting holes are provided on the outer side of the L-shaped mounting plate, a support rod 2 is fixed to the end of the first beam facing away from the L-shaped mounting plate, and the second support rod is detachably fixedly connected to the corresponding docking pipe.

[0013] Beneficial effects of the present invention:

[0014] 1. Move the square slide bar inside the square tube to move the cylinder to the top of the gas pipeline that needs to be cleaned. That is, the cylinder is arranged above the semicircular rubber tube (semicircular cross section). Place the telescopic folding bucket filled with water (detergent) between two adjacent arc-shaped plates. Connect the water outlet pipe at the bottom of the telescopic folding bucket to the water pipeline. Then, use the electric push rod to move the sealing plate to the inside of the control box to seal the two ends of the gas pipeline. Open the valve three inside the reversing pipe one at both ends of the cylinder, open the valve two inside the water pipeline, open the valve one in series inside the water pipeline, and stretch the cylinder. The folding bucket folds and contracts under the action of the gravity of the counterweight, so that the water inside it flows into the gas pipeline, the round rubber tube (with a circular cross section) and the connecting pipe through the outlet pipe and the water pipe. The output end of the cylinder moves the square tube downward, causing the square slide bar to move the cylinder downward, and the cylinder squeezes the semicircular rubber tube so that it is squeezed into the semicircular base tube (with a semicircular cross section) in an arc shape. During the downward movement of the semicircular rubber tube, the internal space of the gas pipeline is reduced, and the water squeezed out of the gas pipeline flows into the telescopic folding bucket. Then the cylinder moves the cylinder upward, and the telescopic The water in the foldable water bucket is refilled into the gas pipeline under the pressure of the counterweight, so that the water can circulate back and forth in the gas pipeline and the telescopic foldable water bucket, making it easy to use the impact force of the water flow to clean the inner wall of the gas pipeline, the round rubber tube and the connecting pipe. In addition, brushes are fixed on the inner sides of the semicircular rubber hose and the semicircular base tube, and the brushes are evenly arranged along the length direction of the gas pipeline. In the process of the semicircular rubber tube moving downward, the brushes on the semicircular rubber tube and the brushes on the semicircular base tube rub against each other, and the semicircular rubber tube is scrubbed with the water. The inner wall of the tube and the semicircular base tube is conducive to improving the cleaning efficiency of the inside of the gas pipeline. By arranging a brush inside the gas pipeline, dust and floating objects in the air can be filtered with the help of the brush to further purify the air. In the process of the brushes rubbing against each other, the brushes themselves are also cleaned synchronously. In addition, a counterweight block is fixed above the telescopic folding water bucket. The counterweight block can always apply downward pressure to the telescopic folding water bucket, thereby keeping the inside of the gas pipeline always filled with water, further improving the cleaning effect, eliminating the need for manual disassembly of the pipeline for cleaning, and improving the pipeline cleaning efficiency.

[0015] 2. By connecting and fixing a reversing pipe 1 connected to the corresponding docking pipe at both ends of the cylinder, when the cylinder moves up and down to clean the gas pipeline, the air blown by the blower is blown from the connecting pipe 2 into the reversing pipe 1, and then the gas flows through the cylinder to the reversing pipe 1 at the other end of the cylinder, and finally is transported to the room from the corresponding connecting pipe 2. Similarly, the indoor air is sucked into the cylinder connected to the exhaust fan through the connecting pipe 2 and the reversing pipe 1 during the cleaning process, and finally is pumped to the outside by the exhaust fan, thereby achieving indoor ventilation during the cleaning of the gas pipeline, solving the problem of stopping air transportation during the cleaning of the gas pipeline. The square slide bar inside the square tube can be moved as needed to selectively move the cylinder above the gas pipeline that needs to be cleaned, so as to achieve the cleaning of one pipeline separately or two pipelines simultaneously. A round rubber tube is fixed to one end of the semicircular base tube. The round rubber tube has two main functions: first, when the cylinder squeezes the semicircular rubber tube downward, the round rubber tube can be deformed to promote the movement of the semicircular rubber tube; second, after the water washing of the gas pipeline is completed, the round rubber tube bends and can bend the docking pipeline toward the direction of the gas pipeline, so that the residual water in the control box and the connecting pipe can be discharged through the water pipe.

[0016] 3. By opening valve 4 on the reversing pipe 2 between the two cylinders, the two cylinders are connected. During the cleaning of the gas pipeline, when a large amount of fresh air needs to be transported into the room, the blower can be turned on separately and the exhaust fan can be turned off. At this time, the air blown out by the outdoor blower flows into the two cylinders from the reversing pipe 1 at the corresponding position, and then flows into the room from the reversing pipe 1 at the other end of the two cylinders, thereby realizing simultaneous air supply to two different directions in the room. When a large amount of turbid air in the room needs to be sucked to the outside, the exhaust fan can be turned on separately and the blower can be turned off. At this time, the outdoor exhaust fan draws gas to the corresponding gas pipeline, thereby causing the turbid air in the room to be sucked into the cylinder through the pipe openings of the two connecting pipes 2 in the room, and then sucked out, thereby realizing the discharge of fresh air and the suction of turbid air in different directions in the room.

[0031] Working principle: When in use, the air purification device is installed on the wall through the L-shaped mounting plate 100, wherein the connecting pipe 2 320 connected to the blower 800 and the exhaust fan 900 is located outdoors, and the rest can be installed indoors. When the gas pipeline 200 needs to be cleaned, here we take the cleaning of the gas pipeline 200 connected to the blower 800 as an example, move the square slide bar 630 at one end of the square tube 620, so that the cylinder 500 at one end of the square slide bar 630 moves to the top of the semicircular rubber tube 220, open the valve 2 of the two reversing tubes 510, and the output end of the electric push rod 332 moves with the sealing plate 331 to the inside of the control box 330 to block the two ends of the gas pipeline 200.
