Description

Technical Field

[0001] This utility model belongs to the field of technical improvement of pipe dredging equipment, and in particular relates to a pipe dredging device based on a moving guide wire. Background Technology

[0002] Drainage pipes are commonly used for discharging domestic wastewater. The discharged domestic sewage contains a large amount of hair shed during daily washing such as hand washing, face washing, and hair washing, as well as a large amount of grease and vegetable scraps discharged from homes or restaurants, and other items that may have been accidentally dropped. These debris can easily cause blockages when they accumulate in the drainage pipes, and over a long period of time, they can form solid, hard calcifications, affecting the normal discharge of sewage and inconveniencing residents' daily lives. Therefore, it is necessary to use a drain cleaner to unclog the pipes.

[0003] Existing pipe unclogging products are divided into traditional suction cup type, soft spring hand-crank type, and pneumatic type.

[0004] Traditional suction cup type: too laborious and time-consuming, requires constant manual suction back and forth, has a low success rate in clearing blockages, and is also troublesome to clean.

[0005] Soft spring hand crank: It requires certain techniques and skills. Ordinary people are not professional drain cleaners, nor do they use it every day, so it is difficult for them to master the techniques.

[0006] Pneumatic type: When using it, sewage from the drain pipes can easily splash onto the ground and may even burst the pipes. The probability of it being able to unclog is not high, and cleaning the product itself is also troublesome.

[0007] Current drain cleaners are all too laborious to use, take a long time to unclog, have a low success rate, require cleaning, are troublesome to clean, and require certain techniques that are difficult to master. They are also too troublesome to use, and sewage from the drain pipes can easily splash onto the ground and may even burst the pipes. Utility Model Content
