CN201158849Y - Multi-purpose deodorant floor drain - Google Patents

Abstract

The utility model relates to a multipurpose deodorizing floor drain, which comprises components such as a jacket, a decontamination grate, a floor drain main body, a main body sealing ring, a main body decontamination grate and the like. A deformed sealing sheet made of high elastic rubber or plastic that can automatically open and close the drain outlet is installed inside the main body of the floor drain. The deformed sealing sheet can be trumpet-shaped, flat-mouth-shaped or pacifier-shaped. An umbrella-shaped detachable and replaceable rotary spice box is installed under the decontamination grate. The utility model overcomes the defect of the traditional cast iron floor drain that has been used for indoor sewage discharge in buildings for many years, and can prevent sewage and harmful gas from pouring back, avoiding indoor air pollution, and simultaneously avoiding blockage caused by dirt precipitation. Because the spice box that can be opened flexibly is installed on the lower part of the sewage grate, a pleasant fragrance can be emitted in the air. And the structure is simple, practical and reliable, and can be widely used in various places such as families and hotels.

Description

Multi-purpose deodorant floor drain

technical field

The utility model relates to the technical field of water supply and drainage of fixed building facilities, in particular to a deodorizing floor drain for preventing back odor.

Background technique

For many years, the discharge of indoor sewage in existing buildings has generally followed the traditional cast iron floor drain, and there is only a simple water seal between the floor drain and the drainpipe. Therefore, the harmful gas produced by the dirt in the sewer pipe is easy to emerge from the floor drain and enter the room to pollute the air. Moreover, due to the deposition of dirt, it is very easy to block, especially in high-rise residential buildings. Once the sewer is blocked, the sewage in the user's pipes on the lower floor will be poured back, causing serious pollution.

Contents of the invention

The purpose of the utility model is to overcome the deficiencies in the prior art and provide a multi-purpose anti-returning odor and deodorizing floor drain that can prevent sewage and harmful gases from flowing backward.

The technical scheme of the utility model is as follows.

A multi-purpose deodorizing floor drain, comprising a jacket, an upper decontamination grate, a middle floor drain body, a main body sealing ring adjacent to the outside of the floor drain main body, and a main body decontamination grate above the floor drain main body. A deformable seal made of elastic rubber or plastic that can automatically open and close the drain. The shape of the deformed sealing sheet is trumpet shape, flat mouth shape or pacifier shape. Below the decontamination grate, an umbrella-shaped detachable and replaceable rotary spice box is installed, and the spice box is made of plastic.

The utility model overcomes the defects of the traditional cast-iron floor drains that have been used for indoor sewage discharge in buildings for many years, and can prevent sewage and harmful gases from pouring back, avoiding indoor air pollution, and simultaneously avoiding the occurrence of blockage caused by sedimentation of dirt. Because the spice box that can be opened flexibly is installed on the lower part of the sewage grate, a pleasant fragrance can be emitted in the air. And the structure is simple, practical and reliable, and can be widely used in various places such as families and hotels.

Detailed ways

Referring to the accompanying drawings, a multi-purpose floor drain is composed of a floor drain jacket 1, a decontamination grate 2, a spice box 3, a floor drain main body 4, an elastically deformable sealing sheet 5, a main body sealing ring 6, and a main body decontamination grate 7. A trumpet-shaped elastic sealing sheet 5 with high elasticity that gradually becomes thinner from top to bottom is installed inside the floor drain main body 4 . There is a circular shoulder on its top, which is installed on the central hole seat of the main body top cover, and its lower trumpet-shaped sealing sheet 5 is closely attached to the water outlet inner wall of the main body 4 bottoms. When the drainage enters the inside of the main body 4 through the sewage grate 2, the sealing sheet 5 is forced to deform and open by gravity, and the drainage flows out rapidly. When the water flow becomes smaller, the elastic sealing sheet 5 returns to its original shape and is tightly attached to the pipe wall of the main body 4 to prevent backflow of peculiar smell and sewage. Simultaneously this sealing sheet 5 also can be made flat mouth shape, as shown in Figure 2. The upper part of the flat mouth is in the shape of a garden opening, and the thickness decreases from top to bottom. The lower flat mouth is closed in a linear shape. When draining, the sewage flows in from the upper circular opening, and the flat mouth of the lower part is flushed and closed linearly by gravity. After the sewage flows out, the flat mouth-shaped linear closure is elastically closed and then restored to its original state, which can achieve the purpose of deodorizing and deodorizing.
