Abstract

The utility model relates to a deodorant floor drain and particularly relates to a deodorant floor drain which is mainly used for a straight-through sewer pipe. The deodorant floor drain with a simple structure and a low cost and capable of being automatically opened and closed is provided. The deodorant floor drain is provided with a floor drain cover and a sewage receiving pipe; a lever-type valve is arranged below the floor drain cover, the lever-type valve is provided with a rotating shaft, a valve plate and a counterweight sheet, the rotating shaft is arranged on the lower end of the floor drain cover, the valve plate and the counterweight sheet are respectively arranged at two sides of the rotating shaft, by adopting the rotating shaft as a support, the torque of the counterweight sheet is more than that of the valve plate, and the valve plate covers a sewage opening of the floor drain cover; and the upper end of the sewage receiving pipe is connected with the lower end of the floor drain cover. When the sewage is discharged, the pressure of the water flow compresses the valve plate, and the torque of the valve plate is more than that of the counterweight sheet, so the rotating shaft rotates, the valve plate turns downwards to be opened, and the water is discharged. When no sewage is discharged, the torque of the counterweight sheet is restored to be more than that of the valve plate, so the valve plate turns upwards to seal the sewage port of the floor drain cover.

Description

A kind of odour-proof floor drain

Technical field

The utility model relates to the floor drain that is used for sewer pipe, especially relates to a kind of odour-proof floor drain that is mainly used in the straight sewer pipe.

Background technology

There is gas or the current phenomenon of instead overflowing in ordinary straight general formula sewer pipe floor drain, and easily causes indoor stink, and mosquito cockroach etc. climbs into the indoor propagation bacterium easily.In order to address the above problem, the technology report of existing in the industry many deodorizations or anti-overflow floor drain respectively has advantage.But the ubiquity structure is complicated, the shortcoming that cost is higher.

Publication number is that the application for a patent for invention of CN101608465 discloses a kind of stink preventing floor drain pipe mouth, in outer tube body, be set with one with outer tube body in below the interior tube body that communicates, in the mouth of pipe of outer tube body top the filter lid is housed, the lower end of outer tube body is provided with back cover, and middle body place is provided with several outfall.The present invention can be installed in the ground or pond of sewer pipe top, after sewage effluent flows into the back cover of outer tube body lower end through the top mouth of pipe, outfall through middle body place flows into sewer pipe, because the water in the back cover has played good water seal effect, foul smell in the shutoff sewer pipe has good odor-resistant result fully.

Publication number is that the application for a patent for invention of CN101781906A discloses a kind of abnormal-core straight sealing type anti-odor drain, and slide block and two groups of gears and pull bar engagement are formed the system that can be free to slide with sleeve and slide block cover plate.Sleeve is plugged on the support, and support is fixed on enclosure, and hollow float and seal cover board and elastic packing rubber cushion are formed the sealing mat system, fix with pull bar, screen pack and deodorant shell are fixed, form one can relative motion system, deodorant is fixed on the floor drain pedestal.This invention is not subjected to the influence of weather and pipeline pressure fully, reaches deodorization, insect protected and stops to return the effect of water.

Summary of the invention

The purpose of this utility model provides a kind of simple in structure, with low cost, but the odour-proof floor drain of automatic open and close.

The utility model is provided with drain cover and following water is taken over; The drain cover below is provided with the lever valve, and the lever valve is provided with rotating shaft, valve block and weight stack, and the drain cover lower end is located in rotating shaft, valve block and weight stack are located at the rotating shaft both sides respectively, with the rotating shaft is fulcrum, and the moment of weight stack is greater than the moment of valve block, and valve block covers the following mouth of a river of drain cover; Following water is taken over the upper end and is connected with the drain cover lower end.

Square, circular or other geometry that the following mouth of a river of described drain cover can be.

The described lower surface at the mouth of a river down preferably is provided with sealing mat.

Described sewer pipe upper end is connected with the drain cover lower end can be and is threaded or the nested type connection.

Described rotating shaft preferably is installed in the drain cover lower end by bearing.

Described valve block and weight stack are preferably integral structure, preferably are provided with the angle less than 90 ° between valve block and the weight stack, and the turning point of valve block and weight stack and described rotating shaft are connected, and described weight stack is provided with configuration block.

During use, the utility model is placed the sewer pipe of building, water down of the present utility model is taken in the sewer pipe port that inserts building.Instantly during water, water flow pressure compressing valve block can make the moment of the moment of valve block greater than weight stack, and rotating shaft is rotated, and valve block changes down to be opened, and current are discharged.When not descending water, the moment of weight stack returns to the moment greater than valve block, changes the following mouth of a river that closes drain cover again like this on the valve block.

This shows that the utility model has utilized lever principle, only need set up the lever valve in the drain cover lower end, just can realize the automatic open and close drain function.Structure is very simple, and is with low cost, takes out capable of washing in the time of need safeguarding or the replacing accessory.Just can prevent behind the valve closing that gas stink, current from instead overflowing and mosquito cockroach etc. climbs into.
