Kitchen sinks, bathroom washbasins, bathtubs are often blocked by foreign objects such as hair, dirt, dust, grease, vegetable residues, etc. Lighter ones may need to use suction cups to clear the water pipes, and more importantly, they may need to add half a bottle to clear the gel at once. And still have to stand for a while, if the serious blockage may require cleaning company to dredge, spend a lot of money and time.

Therefore, the drainage pipe blockage has always been a situation that various families will encounter. Wait until the drainage pipe is blocked to clean up. It may have caused the breeding of bacteria and the problem of flooding the sink. Especially the dirt in the water pipe increases the number of bacteria. It will affect the health of the family. The vast majority of residents use laborious and time-consuming methods to solve the blockage of the drain pipe of the wash basin, such as: straw (cutting its appearance to be full of dirt), pliers (removing the drain pipe) , Homemade cleaners (soda powder, salt, white vinegar), so manual cleaning of drain pipes is already a must for residents. Now people are busy and do not have time to clean the sink. Regular use of dredge glue to clean may cause excessive dredge glue or It is impossible to accurately know whether the water pipe is blocked and needs to be cleaned.

The conventional water pipe dredging and cleaning technology, for example, the I613343 invention patent of the Republic of China "Pipe Hair Dredging Device", that is, a pipe hair dredging device is disclosed, which is composed of a handle end, a long rod section, a convex hook section and a hook The end is integrally formed; wherein, the handle end is provided with a drawing hole and an indicating hole, the long rod section is a round rod-shaped rod body, and the convex hook section is provided with a plurality of convex hooks on the side of the rod body, and the tube The hook end provided at the end of the road hair clearer is flat and slightly blade-shaped, and the same side as the convex hook section has a plurality of hooks on the side of the convex hook; according to this structure, the convex hook section and the hook of the hook end are used Those who remove the hair clogged in the drainage pipe and achieve a structure that is easy to mass produce and easy to operate.
