Description

[Detailed Description of the Invention] The present invention relates to a drain port body, and the drain port body of the present invention belongs to the category of traps used for drainage on the floor of a bath or the like or in a sink.

The drain outlet body of the present invention is particularly designed for use in high-rise housing such as public housing and condominiums.

Conventional traps aim to achieve an odor-preventing effect by sealing the trap with residual water inside the trap body, but during long trips or during the dry summer season, this residual water evaporates in a relatively short period of time. However, the deodorizing effect cannot be sustained for a long period of time.

The present invention aims to provide a drain port body which has such drawbacks and is designed to be reliably effective against insects that try to invade through the drain pipe, and to be easy to install. be.

That is, the present invention consists of a flange portion connected to a drain port, a nozzle-shaped portion connected to the flange portion and having a hollow cylindrical circumferential wall made of an elastic material crushed so as to have a tapered side surface shape, and the nozzle portion. and a tip made of the material having a curved surface that is connected to the nozzle and maintains a seal by abutting the inner surface; A drain port body that releases contact between inner surfaces and allows waste water to flow out to the outside, and when a predetermined amount of waste water has flowed out, the restoring force of the material restores the original contact state and maintains the seal. exists in

Next, the present invention will be explained based on drawings showing embodiments.

FIG. 1 is a plan view of the drain port body of the present invention, FIG. 2 is a perspective view of the present invention, and FIG. 3 is a side sectional view of the entire drain port body of the present invention.

As shown in FIGS. 2 and 3, the drain outlet body of the present invention includes a flange portion 1, a nozzle-shaped portion 2, and a tip portion 3.

The drain port body of the present invention is used by being inserted into a connecting portion between a drain port and a drain pipe, such as a sink or a front stand, and the flange portion is connected to the drain port.

The flange portion 1 is provided so as to protrude from the upper peripheral edge of the nozzle-shaped portion 2, and is generally configured in a circular shape as shown in FIG.

FIG. 14 shows the opening of the drain body of the present invention, through which waste water flows into the drain body.

The nozzle-shaped part 2 connected to the flange part 1 is formed by crushing the circumferential wall of a hollow cylindrical tube made of an elastic material so that its side surface has a tapered shape.

FIG. 3 shows an embodiment in which the peripheral wall is flattened by crushing it from a position appropriately away from the flange portion 1 to form a tapered shape.

In the embodiment shown in FIG. 3, the tip portion 3 is rounded toward the upper right with respect to the center line of the nozzle-shaped portion 2, and has a curved surface.

As a result, the upper wall 30 and lower wall 31 constituting the distal end portion 3 come into contact with each other on their inner surfaces, thereby maintaining the sealing of the drainage eye body outlet.

The tip part 3 may be prepared separately and attached to the lower part of the nozzle part, but as shown in FIG.
It is preferable to extend the crushed peripheral walls 20 and 21 to form an upper wall 30 and a lower wall 31 to form the tip.

That is, it is preferable that the nozzle-shaped part 2 and the tip part 3 are integrally molded, and furthermore, it is preferable that the flange part 1 is also integrally molded using a mold.

As the members constituting the tip portion 3 and the nozzle-shaped portion 2, it is appropriate to use elastic materials such as rubber and plastics.

As mentioned above, the upper wall 30 and the lower wall 31 of the tip part 3 are in contact with each other on their inner surfaces and are attached to each other, so that the drain port is normally sealed, but there is a possibility that the upper wall 30 and the lower wall 31 are in contact with each other on their inner surfaces. When a certain amount of wastewater has accumulated, the tip part 3 is released from the attachment and the wastewater is allowed to flow out through the drainage hole 32.

That is, the tip is normally in a rounded state as shown by the solid line in Figure 3, but when wastewater flowing out from the drain of a sink or the like accumulates in the cavity 23 of the nozzle-shaped part 2, the weight of the wastewater (sewage) When the force that causes the tip portion 3 to become rounded cannot be resisted, a drainage hole 32 is formed as shown by the dotted line in FIG. 3 to allow the drainage to flow outside.

However, leakage does not always occur continuously.

That is, since a resilient material is used for the tip 3, after a predetermined amount of water has been drained, the tip returns to its original state due to the restoring force of the material and maintains the seal again. .

FIG. 4 shows an example of how the drain outlet body of the present invention is attached to a drain outlet such as a sink.

In Fig. 4, 5 indicates a drain port of a sink, etc., and 6 indicates a drain pipe.

As shown in FIG. 4 illustrating how the drain port body of the present invention is used, the drain port body of the present invention is constructed by inserting a flange portion 1 into a connecting portion between a drain port 5 and a drain pipe 6, and tightening it with a nut 7. fixed,
In addition, as shown in FIG. 4, the end of the flange portion 1 is brought into contact with the inner surface of the wall (pipe wall) 8 of the drain port 5 or the drain pipe 6 to provide a backing effect between the drain port 5 and the drain pipe 6, and the drain pipe is closed. It will be installed in 6.

The drain port body 2 of the present invention in FIG. 4 is shown in a front view (right cross section in FIG. 3).

When waste water (sewage) flows in from the drain port 5 of the side sink, etc., the waste water collects in the cavity of the nozzle-shaped part 2 (Fig. 3), and when the tip part cannot resist the weight of the collected waste water, the waste water collects in the cavity (Fig. 3). The clothes are partially untied and drainage begins.

Furthermore, depending on the weight of sewage and the weight of drainage from the drain port,
A lateral force acts on the tip, and the rounded tip 3 gradually moves in the perpendicular direction, approaching the state shown by the dotted line in FIG.
The attachment of the tip end is further released and the diameter of the drain hole 32 is expanded, resulting in the state shown by the dotted line in FIG.

When the weight of the sewage becomes lighter or the sewage disappears, or when the flow of the waste water stops and the weight of the waste water becomes 0, the tip instantly curls again due to its restoring force, and at the same time, the material, for example, rubber and the rubber surface adhere together. This allows the air inside the drain port to be completely shut off without water, unlike a trap.

According to the drain port body of the present invention, the tip maintains a seal by adhesion, so insects that enter through the drain pipe can be completely shut out, and the drain hole can quickly return to its original state even after opening. Because it can be restored and operates reliably, it has excellent drainage effects, is extremely effective in odor and insect repellent, and can be used suitably for bath floors and sink drainage, and is easy to install and can be made small. It has extremely high practical value, especially as a drainage port for high-rise housing such as public housing and condominiums with narrow spaces.
