Sewer pipe orifice floor drain

Abstract

The invention relates to the technical field of drainage pipe fittings for buildings, in particular to a sewer pipe orifice floor drain. The sewer pipe orifice floor drain comprises a main body, a water seal assembly and a movable assembly, wherein the water seal assembly comprises an inner pipe arranged at a notch of a water inlet through groove in the bottom of the main body, an outer pipe eccentrically arranged outside the inner pipe in a sleeving mode and a sealing cover rotationally connected to a pipe opening in the bottom of the outer pipe and matched with the pipe opening; a pipe opening in the top of the outer pipe is fixed to the bottom of the main body; a set of drainage ports are formed in the pipe body, close to the middle upper part, of the outer pipe; the movable assembly comprises a guide pipe, a floater and a three-way pipe; permeation holes are evenly distributed in a pipe body of the guide pipe; the floater is freely connected into the guide pipe in a sliding mode; a main pipe of the three-way pipe vertically extends downwards into the guide pipe through a pipe opening in the top of the guide pipe; a first hose is hermetically fixed at a pipe opening of the main pipe; and a second hose is hermetically arranged on a pipe opening of each branch pipe. The sewer pipe orifice floor drain can effectively solve the problems that an existing floor drain is low in drainage speed and poor in deodorization and insect prevention functions.
