Description

DEVICE FOR BLOCKING ODORS FROM DRAINS}

The present invention relates to a drain odor blocking device. More specifically, when water flows in, the middle cap part is lowered by pressure to discharge the water, and a plurality of magnets located at the bottom of the middle cap part push each other with the same polarity. It relates to a drain odor blocking device in which the middle cap portion is raised and lowered to seal the drain.

Generally, drain pipes are buried in bathroom floors, bathtubs, and sinks to drain domestic sewage. In addition, domestic sewage contains various organic substances and easily decays, creating a foul odor.

These odors backflow and create a nuisance that flows into the room along the drain pipe.

Conventionally, U-shaped odor blocking pipes are used to remove bad odors flowing back into sewers due to water constantly accumulating in the odor blocking pipes.

However, it is difficult to manage because waste continues to accumulate and requires frequent disassembly and cleaning. Also, in the case of washbasins and sinks, there are many restrictions on installation because the sewer pipe protrudes from the ground at a certain length and is installed in a fitting manner.

Because of this, there is a disadvantage that it cannot be used on bathroom and toilet floors.

In order to improve this problem, conventionally, on the floor of bathrooms and toilets, a certain portion of a drain trap that allows a certain amount of water to accumulate around the entrance of the drain pipe is submerged in the accumulated water to block backflow of bad odors. However, it had the disadvantage of not draining smoothly and taking a long time to drain.

To compensate for these shortcomings, plastic tube-shaped pipes have been developed and applied to quickly drain water and block odors.

However, these tube-shaped pipes are compressed using leaf springs or the viscosity of water, so when used continuously, their function deteriorates due to adhesion of debris, etc., causing gaps in the compressed parts, causing bad odors and cockroaches to enter through these gaps.

It includes a magnet portion 400 that is provided and lifts the middle cap portion with a mutually pushing force.

Referring to Figures 2 and 3, the lower body portion 100 is inserted into the drain hole and serves as a passage through which water flowing in from the outside can be moved to the drain hole.

To this end, the lower body portion 100 further includes a pipe portion 110, a support frame 120, and a discharge hole 130.

The pipe portion 110 is formed with a diameter that can be in close contact with the inner peripheral surface of the drain and is formed in a tubular shape that is press-fitted into the inside of the drain.

The support frame 120 is formed as a U-shaped frame by connecting ends extending in a vertical direction from both lower sides of the pipe portion 110 in parallel to each other.

The discharge hole 130 is open on both sides of the support frame 120, and is formed as an open space in the lower part of the pipe portion 110.

Due to this, when water flowing into the upper body portion 200, which will be described later, moves to the lower part of the pipe portion 110, it moves into the open space hole, allowing the water to escape through the drain.

As shown in FIGS. 3 and 4, the lower body portion 100 of the drain odor blocking device 10 according to an embodiment of the present invention may further include a guide portion 140.

The guide part 140 is formed as a tube perpendicular to one surface of the support frame 120 at a position spaced downward from the center of the circle of the tube part 110 and serves to accommodate the magnet part 400 inside the tube.

In addition, the guide portion 140 accommodates the rod portion 320 of the middle cap portion 300, which will be described later, and prevents the rod portion 320 from shaking or being separated from the support frame 120 when being raised or lowered.

In addition, the guide portion 140 is formed at a lower height than the top surface of the pipe portion 110 to lower the middle cap portion 300 so that water flowing into the upper body portion 200 is discharged into the drain through the discharge hole 130. It is desirable to do so.

As such, the lower body portion 100 of the drain odor blocking device 10 according to an embodiment of the present invention may further include a fastening receiving portion 150.

The fastening receiving part 150 protrudes from the other surface of the support frame 120 and forms a space communicating with the lower part of the guide part 140.

Referring to FIG. 3, the upper body portion 200 is coupled to the upper part of the lower body portion 100 and further includes a main body portion 210, a seating portion 220, and a stopper 230.

The main body 210 is formed in a tube shape and is accommodated inside the tube 110, and serves to temporarily accommodate external water when it flows in.

This main body portion 210 has an outer peripheral surface formed with a diameter corresponding to the inner peripheral surface of the pipe portion 110 and is formed to a predetermined length. And the lower part is formed shorter than the lower part of the pipe part 110, so that the packing part 500, which will be described later, is coupled to the lower part.

For this reason, when the middle cap part 300 is raised and lowered to position the middle cap part 300 inside the packing part 500, the lower part of the pipe part 110 can be sealed to prevent bad odors and water from flowing back from the drain. let it be

Referring to Figures 3 and 4, the seating portion 220 is formed with a flange along the upper portion of the main body portion 210 and is seated on the edge of the drain hole.

That is, the seating portion 220 forms a flange wider than the drain hole and is accommodated inside the pipe portion 110 to prevent the combined body portion 210 from being completely inserted into the drain hole, so that the pipe portion 110 is completely inserted into the drain hole. It serves to prevent insertion.

The stopper 230 forms a frame connecting the upper inner peripheral surface of the main body portion 210 and serves to limit the rise of the middle cap portion 300. This prevents water from flowing back and spreading into the area where the drain is located.

Additionally, the stopper 230 filters out hair and other foreign substances and prevents the main body 210 from being deformed.

As shown in FIG. 3, the upper body portion 200 of the drain odor blocking device 10 according to an embodiment of the present invention further includes a stepped protrusion 240.

The step protrusion 240 is formed as a step along the lower outer peripheral surface of the main body 210, and serves to space the steps in response to the position of the support frame 120 so that the end surface of the support frame 120 is positioned between the steps. Do it.

Here, the end surface of the support frame 120 is a vertically continuous part from both sides of the lower part of the pipe portion 110, and the pipe portion 110 and the main body portion 210 rotate about a vertical axis due to the stepped protrusion 240. It prevents shaking and increases bonding strength.

Referring to Figures 3 and 4, the middle cap part 300 is located at the lower part of the upper body part 200, and is lowered by the water flowing into the upper body part 300, so that the water flows into the drain through the discharge hole 130. It plays a role in discharging.

To this end, the middle cap portion 300 further includes a stopper portion 310 and a rod portion 320.

The stopper portion 310 is formed as a plate with a diameter corresponding to the inner peripheral surface of the upper body portion 200 and one surface of which is curved downward.

That is, the stopper 310 is formed as a disk with a flat center, and is curved downward from the edge of the disk to create a height difference between the center and the circumference.

In addition, the stopper 310 is located inside the packing part 500 coupled to the lower part of the main body 210, so that the edge of the stopper 310 is in close contact with the inner surface of the packing part 500 and rises from the drain. It serves to seal and block bad odors and insects.

To this end, the stopper 310 forms a cover protrusion 311 along the edge to prevent shape deformation due to the rise and fall of the stopper 310, thereby increasing the sealing force.

Referring to Figures 3 and 4, the magnet unit 400 is provided with at least one magnet of the same polarity at the lower part of the middle cap part 300, and serves to lift the middle cap part 300 by pushing each other.

To this end, the magnet unit 400 further includes a first magnet 410, a second magnet 420, and a bar magnet 430.

The first magnet 410 is accommodated inside the guide part 140 and is formed to have a diameter and a predetermined thickness corresponding to the inner peripheral surface of the guide part 140.

The second magnet 420 is arranged to face the same polarity as one surface of the first magnet 410, and is formed in the same shape as the first magnet 410.

The bar magnet 430 extends in the longitudinal direction, is arranged to face the same polarity as one surface of the second magnet 420, and is accommodated inside the rod unit 320.

In this way, when the middle cap portion 300 is lowered, the first magnet 410, the second magnet 420, and the bar magnet 430 that are adjacent to each other in the magnet portion 400 are separated from each other, and the bar magnet 430 is closed. It serves to push the lower part of the unit 310 by a spaced distance.

For example, when explaining the operating process of the magnet part 400 as shown in FIGS. 3 and 4, when water flows into the pipe part 110 installed in the drain, the packing part 500, which will be described later, Water is located at the top of the stopper 310, which is located in close contact with the inside, and is stored as the pipe 110.

At this time, the pressure of the water stored in the pipe part 110 causes the stopper part 310 to descend, causing the rod part 320 to move from the upper part of the guide part 140 to the lower direction.

As a result, the bar magnet 430 accommodated inside the rod portion 320 moves downward along the rod portion 320 and comes adjacent to one surface of the second magnet 420.

In addition, the second magnet 420 moves downward and is adjacent to one surface of the first magnet 410, so that the stopper 310 is located in the upper or central part of the main body 210.

And, due to the lowering of the stopper 310, the water stored in the pipe 110 is discharged into the drain pipe through the discharge hole 130.

At this time, as the water is discharged, the pressure of the water is reduced, so that the first magnets 410 and the second magnets 420, which are adjacent to each other with the same polarity facing each other, are spaced apart.

As a result, the second magnet 420 moves up and down and pushes the bar magnet 430 upward.

As the bar magnet 430 moves upward, the rod portion 320 also moves upward in a vertical direction from the guide portion 140, thereby moving the stopper portion 310 upward.

Here, the remaining water due to the upward movement of the stopper 310 is discharged into the discharge hole 130 through the downward curved surface of the stopper 310, thereby further reducing the pressure of the water and forming the second magnets 420 with the same polarity facing each other. ) and the bar magnets 430 are further spaced apart.

In this way, the stopper portion 310 maintains the elevated position by the elevation of the rod portion 320 in response to the distance between the bar magnets 430, blocking water, insects, and odors coming up through the drain. It becomes possible.

Meanwhile, as shown in Figures 3 and 4, the drain odor blocking device 10 according to an embodiment of the present invention may include a packing part 500 coupled to the lower part of the upper body part.

This packing part 500 further includes a silicone band 510, a fastening jaw part 520, and a close contact part 530.

The silicone band 510 is formed as a band surrounding the lower outer peripheral surface of the main body 210.

The fastening protrusion portion 520 forms a step on the inner upper portion of the silicone band 510 and is fastened to the step protrusion 240 formed on the lower portion of the outer peripheral surface of the main body portion 210 to secure the silicone band 510 to the lower portion of the main body portion 210. It plays a role in firmly bonding to.

The close contact portion 530 forms a step at the inner lower portion of the silicone band 510 to allow the lower end surface of the main body portion 210 to be seated, and is formed as a band surrounding the outer peripheral surface of the lifted middle cap portion 300.

Additionally, the packing portion 500 may further include a receiving step portion 540.

The receiving step portion 540 forms steps on both sides of the outer peripheral surface of the silicone band 510 into which the end surfaces of the support frame 120 are press-fitted.

That is, the receiving step portion 540 prevents the silicone band 510 from rotating about the vertical axis by coupling the end surface of the support frame 120, and the silicone band 510 is attached to the lower part of the main body portion 210. ) can be positioned firmly.
