Background

At present, most of people living in buildings have flush toilets, and the flush toilets generally adopt siphon effect to realize sewage discharge. Such toilets are prone to clogging during use. The blockage of the toilet bowl is a troublesome thing, and when the toilet bowl is blocked, the blockage needs to be assisted by some tools to realize dredging. At present, the common methods are that a toilet is poked by an iron wire, and the problem that the toilet is generally blocked by toilet paper can be solved. If the closestool is blocked by hard excrement, the closestool is soaked for a while and then is pressed to dredge by the sucker type dredge, and most of problems can be solved. If the suction cup type dredger cannot be solved, the spring dredger is adopted for dredging. The spring dredger is divided into a manual dredger and an electric dredger. The manual spring dredger is generally provided and easily bought for a common household, the structure of the manual spring dredger is generally composed of a spring with a length of a plurality of meters and a rocking handle assembly positioned at the tail end of the spring, when the manual spring dredger is used, the spring is plugged into a sewer, then the rocking handle is rotated by hand, the whole spring rotates along with the rocking handle, and the spring is rotated in a manual or electric mode to enable the spring to rotate forwards or backwards along the sewer to realize dredging. The existing dredger is slower in moving speed during manual rotation, better in dredging effect than a sucker type dredger, but still cannot be dredged when the blockage is serious. At this moment, an electric dredging device is needed, and the electric dredging device is generally high in cost and large in size and only available for professional dredging companies.
