The drainage is achieved through the drain opening in the above patent. However, because the drain pipe is a hollow pipe, oil stains are easily accumulated on the inner wall of the drain pipe when the drain pipe passes through, and the more the oil stains are accumulated in the long-term use process, the drain pipe is easily blocked, and the unsmooth drainage is caused.

In order to solve the technical problems, for example, the utility model patent of china, patent number ZL201710928255.8 (publication number CN107700612B), discloses an automatic oil-discharging, dirt-removing and anti-clogging sewer pipe device, which is provided with an automatic dirt-removing oil-discharging spring device and a fan blade type impurity stirring device, and the spring in the automatic dirt-removing oil-discharging spring device is driven to reciprocate and stretch, so as to clean oil dirt on the inner wall of the straight pipe section of the sewer pipe, and when the cleaned oil dirt enters the bent pipe section, the fan blade type impurity stirring device works to stir up the sediments in the bent pipe section and flow out along with water flow. Although the oil stain cleaning of the straight pipe section is realized, in the long-term launching process, oil stains are easy to accumulate in the bent pipe section, and the more the oil stains are accumulated, the blockage of the drain pipe is easy to cause, and the unsmooth drainage is caused.

Therefore, further improvements to existing drainage structures are needed.
