Spring-pushing-ball floor drain capable of preventing water returning

Abstract

The invention discloses a spring-pushing-ball floor drain capable of preventing water returning. The floor drain body is of an integral structure, the interior of the floor drain body is provided with multiple steps and inner threads, a lower inner thread is connected with an outer thread of a drain plug in a matched mode, and a column rod is arranged in a column hole of the drain plug; a spring is installed on the lower portion of the column rod in a sleeving mode, a ball is arranged in the middle of the column rod, and the upper surface of the ball is in contact with the spherical surfaces of protruding platforms in the drain plug; a filter cover is arranged on a fourth plane of the multiple steps, an impurity removing mechanism is movably connected to the filter cover and located in a lower cylinder of a drain cover, and an upper inner thread of a second vertical surface is connected with an outer thread of the drain cover. According to the floor drain, the structure is compact, the design is reasonable, water draining is fast, impurities in sewage can be removed, and the situation that the impurities block a sewer is avoided; meanwhile, dispersion of an undesirable odor in the sewer can be prevented, influence on cleanness of air in a room can be prevented, and particularly, when a pipeline of the next floor is blocked, a water returning phenomenon is unlikely to occur; besides, the surface of the floor drain is treated with a coating, the floor drain is resistant to corrosion of an acid liquid and an alkaline liquid, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of building decoration, in particular to a spring thrust ball type anti-backwater floor drain. Background technique [0002] The floor drain refers to the drainage device connected between the ground and the drainage system. It is an important interface connecting the drainage system and the indoor ground. As an important part of the drainage system in the house, its performance directly affects the quality of the indoor air, and it is important for the bathroom. Odor control is very important.
