U-shaped anti-clogging sewer pipe

Abstract

The invention discloses a U-shaped anti-clogging sewer pipe. The U-shaped anti-clogging sewer pipe comprises a U-shaped pipe, wherein water inlet pipes and a water outlet pipe are connected to two ends of the U-shaped pipe through connectors; the water inlet pipes are of inverted Y-shaped structures, and the number of the water inlet pipes is two; one water inlet pipe is directly connected with the U-shaped pipe, and the other water inlet pipe is fixedly connected with the water inlet pipe; a permeating hole is etched in the bottom of the inclined water inlet pipe; an elbow is arranged on the permeating hole; a back flushing water tank is connected to the tail end of the elbow; a water outlet is formed in the side face of the bottom of the back flushing water tank; a floating rod type piston is arranged inside the back flushing water tank; switching of the water outlet is controlled by the floating rod type piston; besides, the water outlet is connected with the bottom of the U-shaped pipe through an inclined pipe. For the whole device, back flushing on the bottom of the U-shaped pipe is performed by adopting a full-automatic matching structure, thereby preventing U-shaped pipe clogging due to sundry stacking, and improving the sewage discharging capacity; the U-shaped anti-clogging sewer pipe is particularly suitable for a small-caliber U-shaped pipe and sewer pipes with small single-pass water flow.

Description

technical field [0001] The invention relates to the technical field of living appliances, in particular to a U-shaped anti-clogging sewer pipe. Background technique [0002] At present, the discharge of various domestic wastewater has become more and more dependent on the sewer pipes, and in order to prevent the odor and bacteria in the sewer pipes from entering the home environment through the sewer pipes, there are often installations at the entrance of the sewer pipes. A U-shaped elbow to prevent these from entering the home environment, but because the sewer pipe is easy to block, the sewer pipe installed in a large public place or a three-dimensional structure of an apartment structure is just a straight water pipe, which is not hygienic In traditional homes, due to the limited diameter of U-shaped pipes, the sewer pipes of users on the lower floor are easily blocked by debris washed down by the sewer pipes of users on the upper floor. After the sewer pipes are blocked,...

[0002] At present, the discharge of various domestic wastewater has become more and more dependent on the sewer pipes, and in order to prevent the odor and bacteria in the sewer pipes from entering the home environment through the sewer pipes, there are often installations at the entrance of the sewer pipes. A U-shaped elbow to prevent these from entering the home environment, but because the sewer pipe is easy to block, the sewer pipe installed in a large public place or a three-dimensional structure of an apartment structure is just a straight water pipe, which is not hygienic In traditional homes, due to the limited diameter of U-shaped pipes, the sewer pipes of users on the lower floor are easily blocked by debris washed down by the sewer pipes of users on the upper floor. After the sewer pipes are blocked, it is not easy to clear them. It takes professional personnel and tools to unblock it, which brings great inconvenience to our life.
