[0031] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0032] Embodiment 1:

[0033] Please combine Figure 1-4 , a pipeline cleaning device of this embodiment includes:

[0034] The cleaning mechanism comprises a movable tube 2, a mounting plate 1 threadedly sleeved on the outer periphery of the movable tube 2, two telescopic tubes respectively mounted on the outer walls of both sides of the rear end of the movable tube 2, and a scraper 4 mounted on the other ends of the two telescopic tubes, the telescopic tube comprises a fixed tube 17 fixed on the outer periphery of the movable tube 2 and a movable column 18 movably sleeved in the fixed tube 17, the outer periphery of the movable tube 2 is provided with threads, a sealing ring is sleeved on the outer periphery of one end of the movable column 18 located in the fixed tube 17, the scraper 4 is fixed to the other end of the movable column 18, the fixed tube 17 is communicated with the inside of the movable tube 2, the outer periphery of the movable tube 2 is provided with a slide groove 16 arranged along its axial direction, and the tail of the scraper 4 is installed There is a pull hook 3, and after the scraper 4 is extended into the interior of the pipe, air can be inflated into the movable tube 2, so that the movable column 18 can be opened to the outside of the fixed tube 17 under the action of air pressure, and then the scraper 4 can be pressed against the inner wall of the pipe, so that it can be suitable for scenes with different inner diameters of pipes. After the scraper 4 is pressed against the inner wall of the pipe, the movable tube 2 can be rotated clockwise, so that the scraper 4 can be driven to rotate and move forward in the pipe, so that the dirt on the inner wall of the pipe can be scraped off, and the setting of the pull hook 3 can be used to bring out dirt such as hair in the pipe when the scraper 4 is pulled out of the pipe.

[0035] A sealing ring 5 is threadedly sleeved on the outer periphery of the mounting plate 1, and a positioning ring 6 is sleeved on the outer periphery of the mounting plate 1. The outer diameter of the positioning ring 6 is smaller than the outer diameter of the sealing ring 5. The sealing ring 5 is a replaceable accessory and is provided with a plurality of different diameters for standby use. When cleaning, first select a sealing ring 5 of a suitable size, and then tighten it on the outer periphery of the mounting plate 1 until the sealing ring 5 abuts against the positioning ring 6 and stops. Then, the mounting plate 1 together with the sealing ring 5 is clamped at the entrance of the pipeline, thereby fixing the mounting plate to prevent the mounting plate 1 from rotating when the movable pipe 2 rotates.

[0036] The sealing mechanism includes a cover plate 20 and a sealing plug 27 fixed on the outer wall of one side of the cover plate 20. The sealing plug 27 blocks the inner side of the head of the movable tube 2. A second valve core 22 for inflating the inside of the movable tube 2 is installed on the other side of the cover plate 20. The sealing plug 27 is made of rubber, and the outer periphery of the sealing plug 27 matches the inner ring of the movable tube 2. The movable tube 2 is sealed by the sealing plug, so that the air pressure in the movable tube 2 will not change after the movable tube 2 is inflated, thereby ensuring that the scraper 4 can be in a state of pressing against the inner wall of the pipeline.

[0037] The pressurizing mechanism includes a connecting sleeve 23 that is movably mounted on the outside of the movable tube 2 and a plurality of gas delivery components mounted on the mounting plate 1. One end of the connecting sleeve 23 is rotatably connected to the mounting plate 1. A slider 24 is fixed to the inner wall of the movable tube 2. One end of the slider 24 extends into the slide groove 16 and slides therewith. The gas delivery components include a gas cylinder 10 fixed on the mounting plate 1, a piston plate arranged in the gas cylinder 10, a piston column 13 fixed on the piston plate, and a piston rod 13 mounted on the gas cylinder 10 for driving the movable tube 2 when the connecting sleeve 23 rotates. The transmission member for the reciprocating movement of the piston rod 13 includes a driven bevel gear 11 rotating on the outer periphery of the cylinder 10, a toggle column 26 fixed on a circular surface of one side of the driven bevel gear 11 at a position deviating from the center of the circle, a connecting plate 14 fixed on one end of the piston rod 13 located outside the cylinder 10, a connecting rod 15 fixed on the connecting plate 14, and a fixed frame 12 fixed on the other end of the connecting rod 15. The fixed frame 12 is movably sleeved on the outside of the toggle column 26, and the length of the inner diameter of the fixed frame 12 is greater than the rotational radius of the toggle column 26. The outer periphery of the connecting sleeve 23 is sleeved with a driving bevel gear 25 meshing with the driven bevel gear 11. An outlet pipe is installed at one end of the cylinder 10, and the other end of the outlet pipe extends to the side of the mounting plate 1 away from the cylinder 10. An inlet pipe is also installed on the side wall of the cylinder 10. Both the inlet pipe and the outlet pipe are equipped with a one-way valve. The one-way valve on the inlet pipe allows the inlet pipe to only inhale external air into the cylinder 10, while the one-way valve on the outlet pipe allows the air in the cylinder 10 to enter the pipeline through it. At the same time, it also prevents the air in the pipeline from entering the interior of the air cylinder 10. When the movable tube 2 rotates, the connecting sleeve 23 can be driven to rotate. The arrangement of the transmission member enables the connecting sleeve 23 to drive the driven bevel gear 11 to rotate after the rotation, and then drive the piston column 13 to reciprocate in the air cylinder 10, so that the outside air can be first sucked into the interior of the air cylinder 10, and then the air in the air cylinder 10 is transported to the pipeline, thereby increasing the pressure in the pipeline, which is helpful to dredge the pipeline and prevent odor from leaking.

[0038] The implementation principle of this embodiment is: when cleaning the pipeline, first select a sealing ring 5 of suitable size, then tighten the sealing ring 5 on the mounting plate 1, then extend the tail of the movable pipe and the scraper 4 into the pipeline, and then clamp the sealing ring 5 and the mounting plate at the pipeline entrance;

[0039] Then, the sealing plug 27 is sealed at the head of the movable tube 2, and then air is inflated into the movable tube 2 through the second valve core 22, so that the movable column 18 is opened to the outside of the fixed tube 17, and the air inflating into the movable tube 2 is stopped until the scraper 4 is pressed against the inner wall of the pipe, and then the movable tube 2 is rotated clockwise, so that the scraper 4 can move forward in the pipe while rotating, so as to scrape off the dirt on the inner wall of the pipe;

[0040] When the movable tube 2 rotates, the connecting sleeve 23 can be driven to rotate. The transmission member is arranged so that after the connecting sleeve 23 rotates, the driven bevel gear 11 can be driven to rotate through the active bevel gear 25. After the driven bevel gear 11 rotates, the fixed frame 12 is driven to reciprocate through the toggle column 26. The fixed frame 12 then drives the piston column 13 to reciprocate in the air cylinder 10 through the connecting rod 15, so that the outside air can be first sucked into the air cylinder 10, and then the air in the air cylinder 10 is transported to the pipeline, thereby increasing the pressure in the pipeline, which is helpful for unblocking the pipeline and preventing odor from leaking out.

[0041] After the cleaning is completed, the entire device is pulled out of the cleaning tube 2, and the retractor 3 can bring the hair in the tube out of the tube during the process of withdrawing from the tube.

[0042] Embodiment 2:

[0043] Combination Figure 1 and Figure 4 Based on Example 1, this embodiment is further improved in that: a fixing ring 19 is fixed on the cover plate 20, a handle 21 is fixed on the outer periphery of the fixing ring 19, the fixing ring 19 is movably sleeved on the outer periphery of the movable tube 2, and a locking bolt 28 is screwed on the outer periphery of the fixing ring 19, and one end of the locking bolt 28 abuts against the outer periphery of the movable tube 2.

[0044] The implementation principle of this embodiment is: while using the sealing plug 27 to block the pipe opening of the movable tube 2, the fixing ring 19 can be sleeved on the outside of the movable tube 2. After the sealing plug 27 is tightened, the locking bolt 28 is tightened, so that the fixing ring 19 is locked by relying on the static friction between the locking bolt 28 and the outer wall of the movable tube 2, and the sealing plug 27 is also locked. After that, when rotating the movable tube 2, the handle 21 can be held to rotate it, which not only saves effort but also makes the rotation more convenient.

[0045] Embodiment 3:

[0046] Combination Figure 1 and Figure 3 Based on the embodiment 1, the present embodiment is further improved in that: a mounting groove 7 is provided on the outer periphery of the sealing ring 5, an inflatable rubber ring 8 is installed in the mounting groove 7, a first valve core 9 for inflating the inflatable rubber ring 8 is installed on the sealing ring 5, the first valve core 9 is connected to the inside of the inflatable rubber ring 8, and the inflatable rubber ring 8 is inflated by the first valve core 9, so that the inflatable rubber ring 8 can expand.

[0047] The implementation principle of this embodiment is: after the sealing ring 5 is placed into the pipeline, air is inflated into the inflatable rubber ring 8 through the first valve core 9, so that the inflatable rubber ring 8 expands and then presses against the inner wall of the pipeline, which not only fixes the mounting plate 1 at the pipeline entrance, but also makes the pipeline better sealed, effectively preventing odor from escaping when pressurizing the pipeline.

[0048] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
