M-shape water seal floor drain

Abstract

The M-shaped water seal floor drain includes top board with water inlet, water inlet barrel around the water inlet and below the top board and water outlet barrel around the water inlet barrel, as well as cup with cup bottom and cup wall inserted into the interval between the water inlet barrel and the water outlet barrel. There are interval between the top of the cup wall and the bottom of the top board, and interval between the bottom of the water inlet barrel and the bottom of the cup. The top board of the water seal floor drain may be closed to ground to avoid bad smell to overflow through peripheral of the floor drain, resulting in high deodorizing effect. The water seal floor drain has M-shaped cross section, deep sealing water and excellent sealing effect.

Description

technical field [0001] The invention relates to people's daily necessities, in particular to a floor drain, especially a water-sealed floor drain. Background technique [0002] In order to prevent the odor in the downpipe from entering the room from the floor drain, people have invented a water-sealed floor drain, but the existing water-sealed floor drains have unsatisfactory deodorizing effects. This is due to the following reasons: 1. Existing water-sealed floor drains The water inlet of the floor drain is small and many, and people cannot observe the change of the water seal height in the water seal floor drain from the small water inlet. When the water seal height in the water seal floor drain is low, the water seal floor drain cannot play the role of deodorization. 2. The water seal depth of the existing water-sealed floor drains is generally not enough, and the water storage capacity is small. The water in the water-sealed floor drain is easy to dry up, and the sealing...

Problems solved by technology

[0002] In order to prevent the odor in the downpipe from entering the room from the floor drain, people have invented a water-sealed floor drain, but the existing water-sealed floor drains have unsatisfactory deodorizing effects. This is due to the following reasons: 1. Existing water-sealed floor drains The water inlet of the floor drain is small and many, and people cannot observe the change of the water seal height in the water seal floor drain from the small water inlet. When the water seal height in the water seal floor drain is low, the water seal floor drain cannot play the role of deodorization

2. The water seal depth of existing water-sealed floor drains is generally not enough, and the water storage capacity is small. The water in the water-sealed floor drain is easy to dry up, and it is easy to lose the sealing effect of the water seal

3. The sealing of the water-sealed floor drain itself and the surrounding materials is not good, causing the odor to overflow from the surrounding of the floor drain

4. Most of the existing water-sealed floor drains are made of metal or plastic. These materials have poor strength, poor corrosion resistance, short service life, easy to expand and deform when exposed to cold or heat, and cannot be bonded with cement; in addition, plastic floor drains are not easy to degrade ,Not environmentally friendly
