Abstract
The utility model relates to a smell preventing device for the floor drains of sewers. The utility model is characterized in that the utility model is composed of a mouth cover and a cylindrical water return device which are connected into a whole. The outside diameter of the cylindrical water return device matches with the inside diameter of the sewage pipe of a floor drain, and the cylindrical water return device is arranged in the sewage pipe. The surface of the mouth cover is provided with a drain opening in the shape of a small half circle. A water outlet hole in the shape of a small half circle is arranged on the lower end of the cylindrical water return device opposite to the position of the drain opening. An S-shaped water return passage is formed in the cylindrical water return device by using two parallel spacer plates, and a high sealing liquid column can be formed in the middle position of the channel. The utility model which is arranged on the sewage pipes of floor drains can achieve good sealing function.
Description
The utility model belongs to a kind of sewer floor drain deodorization device of air, particularly has the floor drain deodorization device of air of S shape passage.
The Odour seal that widely uses so far, do water seal by the button bowl, because the water amount around the passway is few, add the evaporation of moisture, particularly summer, after 1-2 hour, the water level of water seal place just is lower than the water seal line of button bowl, at this moment the foul smell in the soil pipe just can come up by floor drain, pollutes indoor air.
The purpose of this utility model provides a kind of water seal fluid column height, can better solve the floor drain deodorization device of air that emits the foul smell problem from floor drain outward.
For achieving the above object, floor drain deodorization device of air of the present utility model is made up of flap and cylindrical water recovery apparatus, and flap is connected as a single entity with cylindrical water recovery apparatus; The internal diameter of flap matches with the sewer pipe external diameter of its floor drain that is installed in, and the external diameter of cylindrical water recovery apparatus matches with the sewer pipe internal diameter of its floor drain that is installed in; Form a U-shaped cannelure between flap and the cylindrical water recovery apparatus, during use by it the utility model sleeve in floor drain down-comer; Surface one side of flap has the drain gully of a small half of circle: the lower end opposite position of cylindrical water recovery apparatus is equipped with a small half of circular weep hole; The inside of cylindrical water recovery apparatus forms a S shape backwater channel with two parallel baffles, forms a higher sealing fluid column by it, prevents the purpose emitted on the foul smell in the sewer pipe thereby reach.
Use the utility model, successfully solved existing sewer floor drain because of the shallow problem of emitting on the foul smell in the sewer pipe that causes of sealing fluid column; Because its inner S type channel design makes it have certain release of pressure characteristic, promptly when the foul smell pressure in the sewer is big, does not have foul smell yet and overflow simultaneously.

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further described:
A kind of floor drain deodorization device of air is made up of flap (3) and cylindrical water recovery apparatus (1), and flap (3) is connected as a single entity with cylindrical water recovery apparatus (1); The internal diameter of flap (3) matches with sewer pipe (8) external diameter of its cast iron floor drain that is installed in, and the external diameter of cylindrical water recovery apparatus (1) matches with sewer pipe (8) internal diameter of its floor drain that is installed in; Form a U-shaped cannelure (7) between flap (3) and the cylindrical water recovery apparatus (1), during use by it the utility model sleeve on floor drain down-comer (8); Surface one side of flap (3) has the drain gully (4) of a small half of circle; The lower end opposite position of cylindrical water recovery apparatus (1) is equipped with a small half of circular weep hole (5); The inside of cylindrical water recovery apparatus (1) forms a S shape backwater channel (2) with two parallel dividing plates, when using, the utility model is inserted on the sewer pipe (8) of sewer floor drain, in this S shape backwater channel, can forms higher sealing fluid column, thereby reach the better seal effect.
As shown in Figure 4, the utility model for guaranteeing the utility model with the excellent sealing between floor drain down-comer, can adopt plastic material to make the utility model, as plastics or rubber etc. in use; And also can between U-lag (7) and floor drain down-comer (8) top, lay a corrosion resistant rubber seal (6) when mounted, prevent to emerge the slit of foul smell between the same floor drain down-comer of the utility model (8) in the sewer.
The utility model can be made the size of corresponding specification according to the size of employed floor drain.
