Description

A kind of micro-loss in-line floor drain

[technical field]

The utility model relates to a drainage device in a building, in particular to a micro-loss straight-drain floor drain.

[Background technique]

The floor drains of existing buildings usually have the structure of buckle-bowl and U-shaped traps, mainly to prevent the sewage in the sewer from overflowing or odor overflow; the floor drains of U-shaped traps occupy a large space on the next floor , affect the height and appearance of the ceiling on the next floor, and it is extremely difficult to remove the dirt once it is blocked; when the button bowl floor drain drains, the water flow must pass through a very narrow annular gap and pass through two 180-degree sharp turns to discharge the sewage, and the dirt It is easy to deposit and form a blockage, and it is extremely difficult to remove the dirt. Once the water dries up and loses the deodorizing effect, mosquitoes in the sewer will come out of it; in addition, if the sewer is blocked, the sewage will overflow and cause environmental pollution. Bring unnecessary trouble to life. Chinese utility model patent "A reinforced drainage device for anti-mosquito micro-loss water seal with long safety period" (Patent No. 200620058048.9) discloses a floor drain with anti-mosquito micro-loss water seal with long safety period. A sterilizing water-sealed cup is set to prevent the breeding of pests and prevent clogging of the water-sealed cup, so that the life of the water-sealed safety period is relatively long. The floor drain is equipped with a weir wall in the shell to collect and store more water to seal The air connection between the indoor and the external pipe network solves the problem of the water seal being easy to dry up to a certain extent and improves the reliability of the water seal.

[Content of the invention]

The technical problem to be solved by the utility model is to provide a kind of micro-loss straight floor drain with large displacement, anti-clogging, relatively long water seal safety period, good deodorizing effect, and preventing breeding of mosquitoes and bacteria.

In order to solve the above-mentioned technical problems, the technical solution adopted by the utility model is that it includes a housing, a water inlet pipe, and a grate cover. It also includes a water seal cup, the upper part of the water seal cup has an overflow port, the lower part of the water seal cup extends into the shell and around the shell and the lower part of the shell forms a first cavity, and the upper part of the water seal cup is covered on the shell , the lower part of the water inlet pipe extends into the water seal cup and forms a second cavity around the water seal cup and the bottom. The upper part of the water inlet pipe is covered on the water seal cup. The first cavity is connected. The so-called cover installation means that the lower part extends into the carrier and the upper part covers the carrier. The connection of this cover installation can be threaded connection or clamping connection.

The water-sealed cup and the housing can be connected by threads or clamped. The water outlet of the housing is located at the bottom of the housing and is a straight water outlet. The overflow outlet around the upper part of the water seal cup can drain water to the surrounding area, and the drainage area is large; under the same displacement, the side wall of the water seal cup can be made higher, which increases the height of the water seal and the sealing pressure of the water seal. The problem of the short safety period of the floor drain water seal is improved, and it is more effective in preventing insects, blocking, and deodorizing.

The water-sealed cup can add a bactericidal additive during the casting process. Make the utility model have the effect of sterilizing and preventing insects.

The beneficial effect of the utility model is that the water-sealed cup can prevent the breeding of pests, and a bactericidal additive is used to cast the water-sealed cup. The life of the water seal safety period is relatively long, and the lower part of the water inlet pipe extends into the water seal cup and the second cavity formed by the water seal cup and the bottom of the water seal cup to collect more water, and realize the micro-loss water seal with less parts, and the structure Simple, easy to manufacture.
