Description

[Detailed Description of the Invention] This invention relates to a deodorizing ring that prevents discharge of odors of sewage generated in pipes such as sewage basins and rainwater basins.

Figures 1 and 2 show the first deodorizing ring according to the present invention.
FIG. 3 and FIG. 4 show the second embodiment, FIG. 5 and FIG. The appearance of the deodorant belt is shown.

The deodorizing ring of this invention is particularly suitable for the basins shown in Figures 5 and 6, which are used as domestic sewage basins. Items with flanges attached cannot be used.

That is, in the present invention, as shown in FIGS. 1 and 2, the flange-like body 2 attached to the ring body 1 is not located on the entire periphery, but only on approximately half the periphery. A required number (usually 3 to 4) of cutting grooves 3 are provided at both ends or one end of the
is engraved, and O is engraved on the circumferential side of the ring body 1.
A groove 4 for fixing a seal such as a ring is provided around the periphery.

The ring body 1 includes an open-ended cylindrical or windsock-shaped deodorizing band 5 made of a flexible material such as vinyl or cloth.
Attach.

The deodorizing band 5 shown in Fig. 7 is normally attached with a gasket 6 as shown in Figs. It is something.

FIG. 5 shows how the deodorizing ring of the form shown in FIGS. 1 and 2 is used.

As can be seen from these drawings, in the deodorizing ring of the present invention, the ring body 1 fits into the pipe conduit 7, and the outer circumferential side of the brim body 2 fits into the pipe conduit 8.
It is necessary to attach it so that it is in close contact with the end face of the inner wall surface of the body, and both half-split end faces of the brim-shaped body 2 are in close contact with both lateral walls 9, 9, which are inside the box 8 and are slightly inclined inward.

In this case, the height of the horizontal wall varies depending on the box itself or the manufacturing method thereof, and if the circumference of the flanged body 2 is constant, the horizontal wall 9 and the end of the flanged body 2 will not come into close contact with each other.

Therefore, in this invention, since the required number of cutting grooves 3 are carved in one end or both left and right ends of the flanged body 2, unnecessary lengths can be easily removed by hand from the cutting grooves 3. By folding them apart, the side wall 9 and the separated end surface of the brim-like body 2 come into close contact with each other.

By doing so, the box 8 and each part of the brim-like body 2 can be attached in perfect contact with each other.

If wastewater such as sewage or rainwater flows into pipe 7 of pipe 8
The deodorizing belt 5 attached to the deodorizing belt 5 is expanded by the water flow, and the waste water can flow out freely.

However, when the flow of wastewater stops, the tip of the deodorizing band 5 hangs down and becomes closed, thereby preventing the backflow of bad odors from the wastewater and the like.

Moreover, FIGS. 3 and 4 show a state in which a cylindrical body 10, which has a notch that gradually widens from the middle of the side surface toward the terminal end, and has a generally flared shape, is attached to the ring body 1 by pins at two points. show.

The state in which this type of ring is used is shown in FIG. 6, and this cylindrical body 10 prevents the deodorizing ring from coming off and facilitates operation during installation.

As described above, according to the present invention, even if the height of the horizontal wall 9 in the box varies, the arc length of the brim can be easily adjusted manually without using any tools on site. effective.
