Description

Anti-backflow floor drain

Technical Field

The utility model belongs to the technical field of drainage equipment, concretely relates to prevent flowing backward floor drain.

Background

The floor drain is used as a drainage component used in occasions such as toilets and kitchens, is widely used, is a drainage appliance connected with a drainage pipeline system, is an important interface for connecting the drainage pipeline system and indoor ground, has various floor drains in the market in the day before, and has the functions of deodorization and blockage prevention, but in the using process, the functions of deodorization and blockage prevention are not satisfactory, the current commercial houses are almost all high-rise buildings, if a building main sewer pipe is blocked, sewage discharged by upper-rise residents can flow backwards into the rooms of lower-rise residents through the floor drain along the sewer branch pipe, so that pollution in the households of lower-rise residents and damage to furniture are caused, and in addition, peculiar smell in the sewer pipe in summer can be emitted from the floor drain, so that indoor air peculiar smell is caused, and the harm to human bodies is great.

Therefore, the research and development of the anti-backflow floor drain which is simple in structure and can avoid sewage backflow and odor backflow is the key for solving the problems.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a simple structure can avoid sewage to flow backward, the floor drain is prevented flowing backward to foul smell backward.

The utility model aims at realizing like this, including top open-ended floor drain body, the drain pipe that is connected with floor drain body bottom center wash port is taken over, set up the water-stop sheet in the floor drain body, two cavities about the water-stop sheet falls into the floor drain, and a cavity passes through wash port and drain pipe takeover intercommunication, and another cavity is taken over with the drain pipe and is cut off, the water hole is seted up to the water-stop sheet lower extreme, cross the water hole and will control the cavity intercommunication, cross and set up the removable cover who can swing the switching on the water hole, and removable cover is located and takes over the cavity side of intercommunication with the drain pipe, the cavity top that is equipped with removable cover sets up sealed apron.

The utility model discloses following technological effect has:

the inflow and outflow of the floor drain are divided into two relatively independent spaces by adopting the water-stop plate and the movable cover plate, so that the backflow of foul smell generated by sewage backflow can be prevented while the sewer is not influenced; the drainage pipe connecting pipes with different calibers are adopted, so that the drainage pipe connecting pipe can be well suitable for drainage pipes of different models.

Detailed Description

The following description of the present invention is provided with reference to the accompanying drawings, which are not intended to limit the present invention in any way, and any alterations or replacements made based on the teachings of the present invention are all within the protection scope of the present invention.

As shown in the attached drawings 1-2 the utility model discloses a top open-ended floor drain body 1, the drain pipe that is connected with floor drain body bottom center wash port is taken over 2, set up water-stop sheet 3 in the floor drain body, two cavities about water-stop sheet 3 falls into the floor drain, and a cavity passes through wash port and drain pipe and takes over the intercommunication, and another cavity takes over with the drain pipe and cuts off, the water hole has been seted up to the water-stop sheet lower extreme, cross the water hole and will control the cavity intercommunication, cross and set up removable cover 4 that can swing the switching on the water hole, and removable cover 4 is located and takes over the cavity of intercommunication with the drain pipe, the cavity top that is equipped with removable cover sets up sealed apron 5.

And a filter plate 6 is arranged above the cavity separated from the drain pipe connecting pipe, and the filter plate is not higher than the sealing cover plate.

The water-stop sheet 3 is obliquely arranged and is inverted to a cavity separated from the drain pipe connecting pipe.

And a cover plate pressing strip 7 is arranged on the wall of the chamber communicated with the drain pipe connecting pipe, the cover plate pressing strip and the water-stop plate form a closed ring, and the sealing cover plate is buckled and pressed on the closed ring.

The sealing cover plate 5 is provided with slope water, and the slope water flows to a cavity separated from the drain pipe connecting pipe.

And a small drain pipe connecting pipe 8 is coaxially arranged at the joint of the drain pipe connecting pipe 2, and the inner wall of the drain pipe connecting pipe and the outer wall of the small drain pipe connecting pipe are sealed.

The outer diameter of the water discharge pipe connecting pipe 2 is 66mm, and the outer diameter of the small water discharge pipe connecting pipe 8 is 46 mm. The pipe joint is favorable for being directly inserted into two standard pipes (70 pipes and 50 pipes) appointed by the industry, and an adapter is not required.

The sealing cover plate 5 is lower than the upper edge of the floor drain body.

A large filter plate which can be taken and placed is arranged above the sealing cover plate 5, and the upper plane of the large filter plate does not exceed the upper edge of the floor drain body.

The floor drain body 1 is square, and four corners of the lower portion of the floor drain body are in arc adduction. After the arc is contracted, the inside is favorable for draining water, and the outside is favorable for filling bonding materials.

The large filter plate is an open-pore ceramic tile or a stainless steel grid plate.

The utility model discloses theory of operation and working process: when the water-saving filter is used, ground water enters through the filter holes of the large filter plate, part of the ground water flows to the filter plate 6 after passing through the upper inclined plane of the sealing cover plate 5, water flow enters a cavity separated from the drain pipe connecting pipe after passing through the filter plate, the movable cover plate 4 is pushed to be opened by water pressure, the water flow enters the cavity communicated with the drain pipe connecting pipe, and the water flow is discharged through the drain pipe communicated with the drain pipe connecting pipe and then is converged into a main sewer pipe. When the main sewer pipe is blocked, sewage flows back to enter the cavity communicated with the drain pipe connecting pipe through the drain pipe connecting pipe, and the movable cover plate 4 is tightly pressed on the water-stop plate by water pressure to block the water through hole, so that the sewage is prevented from flowing backwards and moving backwards, and the indoor environment is protected from being polluted.
