Description

Technical Field

[0001] The invention belongs to the technical field of toilets, and in particular relates to a cutting anti-clogging intelligent toilet. Background Art

[0002] The connection between the water inlet and the drain outlet of the toilet forms a curved structure with a small diameter and a large depth. It is easy for debris to fall and cause the toilet to be blocked. When the pipe is blocked, three methods are often used to solve it. The first is to use chemicals to corrode the debris, but it cannot be guaranteed that it will have a beneficial effect on all debris. The second is to use a rubber suction cup to suck up the debris. The suction force that the rubber suction cup can generate is small. If it touches the pipe wall during the process of sucking up the debris, the debris and the suction cup will be separated. Repeated suction is required, affecting the use of the toilet. The third is to use hard objects such as wire to hook, but because it is a curved structure, it is easy to push the debris inward, increasing the difficulty of unblocking. After the debris is blocked, the excrement cannot be flushed away, causing odor and affecting the surrounding environment. Summary of the invention
