Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an odor-

More particularly, the present invention relates to an apparatus for blocking odor of a drain hole provided in a drain port of a bathroom or a sink to prevent reverse flow of odor.

Generally, sinks, wash basins and washing machines of various buildings are equipped with drain pipes connected to exhaust pipes for discharging used domestic sewage, and these drain pipes are connected to a drain pipe connected to the outside to discharge domestic sewage.

On the other hand, the discharged domestic sewage contains various organic substances and is easily decayed, so that odor is generated. The odor (odor) generated in this way flowed backward along the drain pipe of each building and flowed into the room to create discomfort.

Many methods have been proposed to overcome the above problems. However, most of them are difficult to install and most of the residues are so high that consumers often cut off the odor by winding a tape around the joint between the discharge pipe and the drain pipe.

Therefore, there is a desperate need for a deodorizing device which not only blocks odor (back odor) flowing back through a drain pipe but also has an original function, that is, an excellent water discharge function, a simple construction, and easy maintenance.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention proposes a device for blocking odor backflowing from a drain hole. But it is not necessarily limited to a drainage port for discharging domestic sewage used in a sink or sink of various buildings.

According to the present invention, an outer cap 10 to be coupled to a drain hole is provided. The outer cap 10 has a structure in which an inner cylinder 11 and a circular plate 12 are integrally formed using a resin material. Cutting grooves (15) are formed on the bottom surface of the disk (12) so as to be easily cut to an appropriate size. The original plate 12 can be cut to an appropriate size and mounted at the inlet of the drain hole. The circular plate 12 has a through hole and a step for receiving the inner cap 20 described later.

According to the present invention, the inner cap 20 having the pressing piece 25 on its outer surface is detachably mounted on the outer cap 10. The inner cap 20 also has a structure in which the cylinder 21 and the circular plate 22 are integrally formed using a resin material. The disc (22) is provided with a net (23) for filtering foreign matter. It is easy to separate the inner cap 20 from the outer cap 10 by picking up the net 23 with a hand or a forceps. On the outer surface of the cylinder (21), a plurality of compression pieces (25) for supporting the oil connection (30) to be described later are provided.

According to the present invention, the oil connector 30 is mounted on the outer surface of the inner cap 20 via the compression piece 25. It is preferred, but not limited, to use the vinyl material which causes natural closure while permitting smooth drainage. In the middle of the oil connection 30, an elastic body 35 for supplementing the odor blocking function can be added. The elastic body (35) has a structure having elasticity and elastic restoring force of length variation.

As a detailed construction of the present invention, the compression piece 25 of the inner cap 20 is provided so as to be rotatable via a hinge shaft 28 and has a step 26 exposed to one side. 2 illustrates a state in which the compression piece 25 is provided at the lower end of the cylinder 21 of the inner cap 20 by the hinge shaft 28. [ It is possible to install the oil contact 30 at the lower end of the cylinder 21 by pressing the pressing piece 25 as shown by the reference numeral 25 'and pressing the pressing piece 25 quickly and tightly. In the case of replacing the oil connection 30, when the lower end of the compression piece 25 and the step 26 exposed to the lower end of the cylinder 21 are pushed up, the state goes back to the state of reference numeral 25 '. Such a compression piece 25 is formed to have a size that is not exposed in the cylinder 21, thereby avoiding interference when the inner cap 20 is separated from the outer cap 10.

At this time, the compression piece 25 may be made of a material different from that of the inner cap 20, and may be installed at 2 to 4 places at regular intervals on the outer circumferential surface of the cylinder 21. [ The diameter (diameter) of the oil connection 30 is determined in consideration of the reduction in diameter when engaged with the compression piece 25.

In addition, according to the present invention, the auxiliary means (40) is installed to assist in blocking the odor while allowing drainage through the inner cap (20). The auxiliary means (40) is a means added to assist the function of the oil connection (30) engaged with the compression piece (25).

The auxiliary means 40 includes a guide bar 41 which is installed on the outer cap 10 so as to face the oil guide 30, a movable block 41 which is removably received on the guide bar 41, (42). The guide base 41 is formed to have a substantially "C" -shaped cross section and is uniformly spaced at a plurality of points on the inner surface of the cylinder 21 of the outer cap 10. The movable block 42 is installed such that one end (outer end) of the movable block 42 is accommodated in the guide base 41 and the other end (inner end) thereof is in contact with the oil connection 30. The guide block 41 may be inclined so that the movable block 42 slides on its own weight to reduce the oil connection 30 or the spring 43 may be mounted between the guide block 41 and the movable block 42 .

In any case, when the guide block 41 and the movable block 42 are used, the drainage can be easily extended together with the oil connection 30 when the drainage is performed, and the oil connection 30 is reduced when the drainage amount is reduced. In FIG. 3, reference numeral 30 'on the left indicates a state in which the movable block 42 is exposed and the diameter of the oil connection 30 is reduced. Thus, even if the elastic body 35 is excluded, it is possible to enhance the operation reliability of the drainage and odor blocking.

On the other hand, it is advantageous to increase the opening and closing force with respect to the oil guide 30 by increasing the length of the movable block 42 and forming it with two steps as compared with that shown in FIG.

The auxiliary means (40) is provided on the inner surface of the inner cap (20) in a divided manner so as to have a movable piece (46) for opening and closing the flow path. Fig. 4 illustrates a state in which the movable piece 46 is provided opposite to the cylinder 21 of the inner cap 20, and Fig. 5 (a) illustrates a state in which the movable piece 46 is divided into six parts. The movable piece 46 is engaged with the inner cap 20 by using a fixing piece 45 which is integrally formed. The movable piece 46 is formed of a material excellent in elastic deformability and resistant to fatigue load. The movable piece 46 is opened to reduce the impact on the oil connection 30, thereby preventing the durability from being weakened. When the drainage is completed, the flow path is closed with the oil connection (30) to block the reverse flow of the smell.

At this time, the movable piece 46 is formed to have a flat or curved cross section by using a material having elasticity, and the elastic piece 47 is further added. Fig. 5 (a) illustrates a movable piece 46 having a planar section, and Fig. 5 (b) illustrates a movable piece 46 having a curved section. Fig. 5 (a) is relatively advantageous for the open operation, and Fig. 5 (b) is relatively advantageous for the closing operation. In the latter case, the movable piece 46 has a hemispherical shape when the flow passage is closed, and extends like the reference numeral 46 'in the drainage process. In any case, as shown in FIG. 5 (c), the flow path cross-sectional area can be maximally expanded in the drainage process.

On the other hand, it is preferable to reduce the thickness of the movable piece 46 toward the center of the edge where the fixing piece 45 is located. When the elastic piece 47 is added to the inside or the outside of the movable piece 46, elastic deformation and durability can be increased.

The compression piece 25 and various auxiliary means 40 of the present invention can be used independently or in combination.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined by the appended claims. It is therefore intended that such variations and modifications fall within the scope of the appended claims.
