Description

Technical Field

[0001] This utility model relates to the field of sewer pipe cleaners, and in particular to a sewer pipe cleaner that prevents backflow and splashing. Background Technology

[0002] A drain cleaner is a device used to unclog drains. When using a drain cleaner, insert one end of the hand-cranked drain cleaner into the blocked drain pipe, ensuring the handle is in the closed position. Then, push the hand-cranked drain cleaner fully into the pipe, open the handle, and gently rotate the drain cleaner to guide it into the blockage. Once the drain cleaner reaches the blockage, begin to rotate the handle forcefully, pushing the plunger to cut the blockage. Continue rotating the handle forcefully until the blockage is cleared or moved. Once the blockage is cleared or moved, continue rotating the drain cleaner and gradually pull it out of the pipe. Clean the drain cleaner thoroughly and store it for future use.

[0003] The inventor discovered in daily work that drain cleaners still have at least the following problems: When using a drain cleaner, insert one end of the hand-cranked drain cleaner into the blocked drain pipe, ensuring the handle is in the closed position, then push the hand-cranked drain cleaner completely into the pipe, open the handle and gently rotate the hand-cranked drain cleaner to bring it into the blockage. Once the hand-cranked drain cleaner reaches the blockage, start to rotate the handle forcefully to push the hand-cranked drain cleaner's spikes to cut the blockage. Continue to rotate the handle forcefully until the blockage is cleared or moved. Once the blockage is cleared or moved, continue to rotate the hand-cranked drain cleaner and gradually pull it out of the pipe. Clean the drain cleaner and store it for future use. When using the drain cleaner, a lot of friction is generated between the plastic parts, which to some extent affects the service life of the drain cleaner. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a drain cleaner that prevents backflow and splashing.

[0006] The effect achieved by the above components is as follows: when using the protective device, the iron column is placed inside the connecting cylinder to replace the plastic, reducing the rotational friction between the plastics and lowering the probability of melting, thereby increasing the service life of the drain cleaner to a certain extent.

[0007] Preferably, the inner wall of the connecting cylinder is provided with a sleeve, the sleeve is fitted onto the surface of the iron column, and the inner wall of the sleeve is uniformly provided with partitions.

[0013] Preferably, a limiting device is provided at one end of the connecting cylinder. The limiting device includes a connecting sleeve, which is sleeved on one end of the connecting cylinder. A rubber conical sleeve is fixedly connected inside the connecting sleeve.

[0014] The effect achieved by the above components is that when using the limiting device, the connecting sleeve is placed on one end of the connecting cylinder, and then the rubber conical sleeve is inserted into the inside of the sewer pipe, thereby preventing water backflow and splashing inside the sewer to a certain extent.

[0015] Preferably, the surface of the rubber conical sleeve is uniformly provided with notches.

[0018] The effect achieved by the above components is that the threaded ring is threaded onto the surface of the threaded groove on the surface of the connecting cylinder, thus confining the connecting sleeve to the surface of the connecting cylinder.

[0019] Preferably, a rubber ring is fixedly connected to the inner wall of the connecting sleeve, and the rubber ring is fitted onto the surface of the connecting sleeve.

[0020] The effect achieved by the above components is that the rubber ring is fitted onto the surface of one end of the connecting cylinder, which can play a certain sealing role.

[0021] In this invention, by setting up a protective device, when using the protective device, an iron column is placed inside the connecting cylinder to replace the plastic, reducing the rotational friction between the plastics and lowering the probability of melting, thereby improving the service life of the drain cleaner to a certain extent.

A spring 5 is installed inside the connecting cylinder 3, and a protective device 6 is installed on the inner wall of the connecting cylinder 3. When using the drain cleaner, insert one end of the hand-cranked drain cleaner into the blocked drain pipe, ensuring that the handle 2 is in the closed position. Then, push the hand-cranked drain cleaner completely into the pipe, open the handle 2, and gently rotate the hand-cranked drain cleaner to bring it into the blockage. Once the hand-cranked drain cleaner reaches the blockage, start to rotate the handle 2 forcefully to push the spikes of the hand-cranked drain cleaner to cut the blockage. Continue to rotate the handle 2 forcefully until the blockage is cleared or moved. Once the blockage is cleared or moved, continue to rotate the hand-cranked drain cleaner and gradually pull it out of the pipe. Clean the drain cleaner and store it for future use.

[0030] Reference Figures 2 to 6The protective device 6 includes an iron column 601, which is installed inside the connecting cylinder 3. The end of the iron column 601 furthest from the connecting cylinder 3 is joined to one end of the spring 5. The end of the iron column 601 closest to the inner wall of the connecting cylinder 3 is located on one side of the inner wall. When using the protective device 6, the iron column 601 is placed inside the connecting cylinder 3 to replace the plastic, reducing the rotational friction between the plastic components and lowering the probability of melting, thereby improving the service life of the drain cleaner to some extent. A sleeve 602 is provided on the inner wall of the connecting cylinder 3, and the sleeve 602 is fitted over the surface of the iron column 601. On the inner wall of sleeve 602, partitions 603 are evenly distributed. These partitions reduce friction caused by rotation and also provide heat dissipation. A circular iron washer 604 is provided on the inner wall of connecting cylinder 3 at the bottom of sleeve 602. This circular iron washer 604 is added between the plastic parts to reduce friction. A circular fixing iron piece 605 is provided on the inner wall of connecting cylinder 3 at the bottom. The iron post 601 and connecting cylinder 3 are positioned close to the inner wall of support plate 1. One end of the connecting cylinder 3 is provided with a limiting device 7, which includes a connecting sleeve 701. The connecting sleeve 701 is fitted onto one end of the connecting cylinder 3, and a rubber conical sleeve 702 is fixedly connected inside the connecting sleeve 701. When using the limiting device 7, the connecting sleeve 701 is fitted onto one end of the connecting cylinder 3, and then the rubber conical sleeve 702 is inserted into the inside of the drain pipe, thereby preventing water backflow and splashing inside the drain pipe to a certain extent. The surface of the rubber conical sleeve 702 is evenly provided with notches 703, through which the iron rod 601 and the spring 5 can easily pass through the rubber conical sleeve 702. The surface of the connecting sleeve 3 has a threaded groove 706. A threaded ring 705 is threadedly fitted onto the surface of the threaded groove 706 on the surface of the connecting sleeve 3. The threaded ring 705 is fixedly connected to one end of the connecting sleeve 701. The threaded ring 705 is threadedly fitted onto the surface of the threaded groove 706 on the surface of the connecting sleeve 3, which can restrict the connecting sleeve 701 to the surface of the connecting sleeve 3. A rubber ring 704 is fixedly connected to the inner wall of the connecting sleeve 701, which is fitted onto the surface of the connecting sleeve 3. The rubber ring 704 is fitted onto the surface of one end of the connecting sleeve 3, which can play a certain sealing role.

[0031] Working principle: When using a drain cleaner, insert one end of the hand-cranked drain cleaner into the blocked drain pipe, ensuring handle 2 is in the closed position. Then, push the hand-cranked drain cleaner fully into the pipe, open handle 2, and gently rotate the drain cleaner to guide it into the blockage. Once the drain cleaner reaches the blockage, begin to rotate handle 2 forcefully, pushing the plunger to cut the blockage. Continue rotating handle 2 forcefully until the blockage is cleared or moved. Once the blockage is cleared or moved, continue rotating the drain cleaner and gradually pull it out of the pipe. Clean the drain cleaner and store it for future use. When using the protective device 6, the iron post 601 is placed inside the connecting cylinder 3. The iron post 601 replaces the plastic to reduce the rotational friction between the plastic parts, thus reducing... To reduce the probability of melting, a circular iron washer 604 is added between the plastic parts to reduce friction between them, thereby improving the service life of the drain cleaner to a certain extent. The sleeve 602 has evenly spaced partitions 603 inside to reduce friction caused by rotation and also to have a heat dissipation effect. When using the limiting device 7, the threaded ring 705 is threaded onto the surface of the threaded groove 706 on the surface of the connecting cylinder 3, which can restrict the connecting sleeve 701 to the surface of the connecting cylinder 3. The rubber ring 704 is fitted onto the surface of one end of the connecting cylinder 3, which can play a certain sealing role. The connecting sleeve 701 is fitted onto one end of the connecting cylinder 3, and then the rubber conical sleeve 702 is inserted into the inside of the drain pipe, thereby preventing the backflow and splashing of water inside the drain to a certain extent. The notch 703 allows the iron column 601 and the spring 5 to pass through the rubber conical sleeve 702.

[0032] It should be noted that all damping rods in this case are telescopic dampers, which can absorb energy during the extension and retraction process.
