Description

[0001] Apparatus for automatic smell interception of drain holes [0002]

The present invention relates to an automobile end device for a drain hole having a structure in which a screw connection is made to block the odor coming from a drain hole and the outlet of the drain hole can be opened and closed by water pressure in the form of a rubber material.

Sectional view of a drainage structure according to the prior art.

The drainage structure 1 according to the prior art FIG. 7 is a drainage structure formed in a sanitary apparatus such as a bathtub 2, for example, and is structured to be attached to the drainage hole 3.

The drain hole structure (1) of the present invention basically includes a drain hole socket (10) and a plug (20) mounted in the drain hole (3). Of course, the drainage structure 1 of the present invention may also include a drainage sleeve 4 for holding the drainage socket 10 in the bath 2, wherein the drainage pipe 5 is connected to the drainage sleeve 4.

The drainage sleeve 4 is disposed under the drainage hole 3 and the drainage socket 10 is screwed to the drainage sleeve 4 via the packing 6 with the bath 2 interposed therebetween, ).

The cap 20 may be integrally made of a single material (e.g., rubber) as a whole, such as a cap of a conventional bathtub drain port. The cap 21 may be made of metal or hard plastic, Can be manufactured and assembled as parts of

There is also. The cap portion 21 is a portion that is raised on the drain hole 11 and the flange 12 of the drain hole socket 10 to cover the drain hole 11 and preferably has a handle 21A.

The plug portion 22 is a member inserted into the drain hole 11 of the drain hole socket 10 and tightly fitted to the inner circumferential surface thereof to tightly seal the drain hole 11. Therefore, the outer diameter of the plug portion 22 corresponds to the inner diameter of the drain hole 11. Preferably, the plug portion 22 is made of an elastic material such as rubber, and when the plug 20 is applied with a force, the plug portion 22 is elastically tightly fitted to the drain hole 11 to block water leakage.

The retaining portion 23 is supported by the inner circumferential surface of the drain hole 11 so that the plug portion 22 does not block the drain hole 11 although the plug 20 is inserted into the drain hole socket 10 So that even if the stopper 20 is fitted in the drain hole 11,

. That is, the holding portion 23 prevents the plug portion 22 from being slightly caught in the drain hole 11 so that a gap 7 is formed around the inner circumferential surface of the drain hole 11, It is a member to be able to escape. The holding portion 23 may have a structure in which the gap portion 7 is formed and the plug portion 22 is held so as not to block the drain hole 11. [

However, in this conventional technique, after the water is discharged to the drain port, it is always necessary to insert the plug into the drain hole to prevent the smell from rising. It is a hassle to prevent odors from coming up even in normal times.

This conventional technique has the problem of opening and closing the cap every time the water flows down a little.

When water is not poured, a technique has been demanded that can automatically prevent the drain hole from coming off the drain.

1. Korean Utility Model Registration Utility Model Registration Bulletin 20-0344231 (Mar. 3, 2004) 2. Registered Utility Model Registration No. 20-0336806 (December 24, 2003) 3. Registration of the Korean Intellectual Property Office (KIPO) 20-0305374 (Feb. 25, 2003)

It is opened only when the water flows into the sewer, and automatically shut off when the water does not flow.

It can be screwed to drainage sleeve and it can block off odor. It does not need to have a separate stopper. It also prevents the smell coming from the threaded screw by putting a shield on the screw thread of the drainage sleeve.

In the case of washing with a washing machine, in the state where water does not flow, the drain hole is blocked so that the smell does not enter the washing tub, and the washing tub is provided with an additional assembly fitting to the washing hose.

In order to solve the above-mentioned problems, the following means are provided.

A drain hole socket (200) having a connection ring (220);

A drainage sleeve (300) having a thread to be engaged with the drainage socket;

And an opening / closing part (400) coupled to the connection ring (220) at one end of the drain hole socket.

    Here, the drain connection socket connection part 130 of the connection socket 100 is further coupled to the drain connection socket 200 at the other end.

When the second step 210 is formed at the other end of the drain hole socket 200 and the first step 110 is formed in the connection socket 100 to connect the drain hole socket and the connection socket, 110 and the second step 210 are tightly coupled with each other.

     In addition, the connection ring 220 of the drain hole socket 200 may have a rectangular step shape, and may be formed in an annular shape across the entire outer surface of the drain hole socket.

In addition, a third step 250 is disposed under the flange of the drain hole socket 200 and is closely connected to the fourth step 350 when the drain hole 300 is coupled with the drain hole 300.

Here, a male screw portion 340 may be provided at a lower portion of the drainage sleeve 300 so as to be threadedly engaged with the drainage of the outside of the drainage sleeve 300

Preferably, when the drain hole socket 200 is coupled to the drain sleeve 300, the connection hole is easily coupled when the drain hole 200 is coupled to the drain hole 300, and is connected smoothly at an upper portion thereof so as not to be detached by a small force. And a connecting jaw 320 is provided.

The opening and closing part 400 includes an opening and closing part inlet 440 and an opening and closing part outlet 410. The material of the opening and closing part 400 is made of rubber.

A shielding film (360) is formed on the external threaded portion of the drainage sleeve to prevent the smell coming on the groove of the screw by the coupling of the drainage attached to the building and the threaded portion.

First, the smell coming from the drain can be blocked.

Second, the connection socket can be attached to connect the hose.

It is possible to attach it firmly during the period of use by constructing it so that it is difficult to detach after it is tightly bonded and bonded at the third step.

It is possible to prevent the smell coming up from the fine coupling of the threads and the thread through the screw connection.

It is easy to replace the fourth opening and closing part.
