Description

Technical Field

[0001] This utility model relates to the technical field of pipe cleaning tools, and specifically to a pipe dredging device that can be operated with one hand. Background Technology

[0002] Drain pipes are often clogged by the accumulation and entanglement of hair, fibers, and other debris, requiring the use of flexible shaft drain cleaners. However, ordinary drain cleaners require one hand to turn the flexible shaft and the other to push it, necessitating coordination and making operation inconvenient. To address this, a drain cleaner that uses rollers to push the flexible shaft has been introduced to the market. In this product, the flexible shaft is machined into a spiral tube shape, with multiple rollers surrounding it. The lines connecting the contact points between the rollers and the flexible shaft form a force conversion structure that matches the spiral of the flexible shaft, similar to the mating structure of internal and external threads. This converts rotation into axial movement. During operation, simply rotating the flexible shaft causes it to contact the rollers, thus pushing the shaft axially.

[0003] For example, Chinese utility model patent CN218502859U discloses a pipe cleaner, including a flexible shaft delivery pipe, a housing, a flexible shaft wound into a helical shape, and push rollers evenly distributed around the flexible shaft inside the delivery pipe. The housing is rotatably connected to and communicates with the delivery pipe. The flexible shaft is wound inside the housing. The push rollers include fixed rollers and movable rollers. The fixed rollers are rotatably connected inside the delivery pipe, and the movable rollers are rotatably connected to a movable roller seat. The movable roller seat is slidably connected to the delivery pipe. A movable roller seat lifting and adjusting mechanism is provided outside the delivery pipe, and the movable roller seat is connected to the lifting and adjusting mechanism. The lifting and adjusting mechanism includes a lever, which is mounted on a pressure cam. The lever can rotate the pressure cam to achieve alternating adjustment of the pressure between the movable rollers and the flexible shaft.

[0004] One hand needs to hold the handle, and the other hand needs to turn the lever. Both hands need to be coordinated, which is inconvenient to operate. Therefore, the structure needs further improvement. Utility Model Content

Detailed Implementation

[0025] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-6As shown, a pipe cleaner that can be operated with one hand includes a housing 1, a receiving cavity 2 formed inside the housing 1, a spring tube 3 disposed inside the receiving cavity 2, the spring tube 3 being wound and stored inside the receiving cavity 2, a conveying pipe 4 rotatably connected to one end of the housing 1, a conveying cavity 5 formed inside the conveying pipe 4 and communicating with the receiving cavity 2, two fixed guide wheels 6 and one movable guide wheel 7 respectively disposed inside the conveying cavity 5, a conveying cavity 8 for conveying the spring tube 3 is formed between the fixed guide wheels 6 and the movable guide wheel 7, a handle 9 is formed at the lower end of the conveying pipe 4, a mounting base 10 is disposed between the conveying pipe 4 and the handle 9, a movable seat 11 is movably disposed inside the mounting base 10, a return spring 12 abuts against the mounting base 10, the movable guide wheel 7 is rotatably disposed on the movable seat 11, and a push button 13 for pushing the movable seat 11 to move is provided on the lower end face of the movable seat 11.

[0027] This utility model, through the design of the push button, enables one-handed operation. In actual use, one can hold the handle with one hand and then press the push button 13 with one finger to control the delivery or rotation of the spring tube. Compared with the prior art, which requires the coordination of both hands, it is simpler to operate and more convenient to use.

[0028] Combination Figure 5 and Figure 6 The lower end of the movable seat 11 is connected to a push block 14, and the lower end face of the push block 14 is formed with a round protrusion 15. The upper end face of the push button 13 is formed with a recess 16 and a protrusion 17 respectively. An inclined surface 18 for the round protrusion 15 to slide is formed between the recess 16 and the protrusion 17. In actual use, when the push button 13 is pushed so that the recess 16 is below the round protrusion 15, the movable seat 11 can be driven to move away from the fixed guide wheel 6 by the action of the return spring 12. At this time, since the movable guide wheel 7 no longer abuts against the end face of the spring tube 3, the spring tube 3 stops pushing and only maintains its rotation. It can fully wrap around and combine with the debris blocking the pipe, so that the debris can be removed later. When the push button 13 is pushed to the other side, the round protrusion 15 will slide onto the end face of the protrusion 17 through the inclined surface 18, and at the same time drive the movable seat 11 to move closer to the fixed guide wheel 6. At this time, since the three guide wheels 6 are respectively against the outer periphery of the spring tube 3, when the spring tube 3 rotates, it drives each guide wheel 6 to rotate together. Each guide wheel 6 will move relative to the spring tube 3 along the spiral groove on the outer wall of the spring tube 3, thereby pushing the spring tube 3 forward along the axis. Rotating the spring tube 3 in the opposite direction will cause the spring tube 3 to retract backward.

[0029] The handle 9 has mounting holes 19 for mounting push buttons 13. The two ends of the push buttons 13 extend out of the mounting holes 19 and form pressing parts 20. By pressing the pressing parts 20 on both sides of the push buttons 13, the position of the push buttons 13 can be controlled, thereby adjusting the working state of the spring tube 3.

[0030] The lower end face of the push button 13 is formed with a limiting part 21, which can prevent the push button 13 from sliding out of the mounting hole 19 and keep it in the mounting hole 19 to move back and forth.

[0031] like Figures 2 to 4 As shown, a connecting pipe 22 is formed at one end of the outer shell 1. The conveying pipe 4 includes a left pipe 23 and a right pipe 24 detachably connected to it. An installation groove 25 for installing the connecting pipe 22 is formed between the left pipe 23 and the right pipe 24. A positioning ring 26 is provided in the installation groove 25. A retaining groove 27 that mates with the positioning ring 26 is formed on the outer periphery of the connecting pipe 22, thereby enabling a rotatable connection between the connecting pipe 22 and the conveying pipe 4.

[0032] See details Figure 1 The other end face of the outer casing 1 is provided with a drill connector 28, which can be used to connect power tools. The other end face of the outer casing 1 is provided with a hand crank 29 at an eccentric position, which can also be used to manually rotate the outer casing.

[0033] like Figure 3 and Figure 4 As shown, a baffle 30 is formed at one end of the conveying pipe 4, and a gasket 31 is provided between the outer shell 1 and the baffle 30. The gasket 31 is sleeved on the outer periphery of the connecting pipe 22 to reduce the friction between the two and reduce wear.

[0034] The fixed guide wheel 6 is rotatably connected to the fixed seat 33, and the fixed seat 33 is fixed in the conveying cavity 5 by fasteners.

[0035] The outer periphery of the connecting pipe 22 is equipped with a bearing 32, which makes the rotation more stable and less prone to shaking.
