Description

Draining device

The invention relates to a drainage device, in particular to a drainage device applied to a drainage hole.

Generally speaking, the drain holes in the bathroom or kitchen are open. In order to avoid the odor of the drainage channel, the connected drainage pipe will be made into a curved type. This curved structure is also called a trap (S-trap, or P-trap). The building regulations of many countries and regions require that the drainage structure of the bathroom or kitchen must have a trap to prevent the return of biogas or other toxic gases, which may cause harmful effects on the human body. In order to prevent foreign matter from blocking the drainage hole, a drainage filter cover is generally installed, but it must have a diversion hole with a large diameter to ensure that the liquid can be discharged and to prevent foreign matter from accumulating in the trap and causing odor. In addition, the water stored in the trap (also called water seal) has the physical phenomenon of being evaporated, so the water seal will disappear when it is not used for a long time, and there will be odors and the return of biogas.

In addition, the traditional urinal (or urinal) uses frequent flushing to keep the urinal clean and dilute the urine and its residual taste. Similarly, in order to avoid the odor of the drain, a trap is also set up, but the upper end of the trap to the drain port of the urinal will still produce a odor due to residual urine. In addition, in order to achieve the purpose of environmental protection and saving water resources, non-flushing urinals have been introduced on the market. The non-flushing urinal is equipped with an odor-proof filter, which has an oily insulating liquid inside, and the principle of a heavier specific gravity of the permeated liquid (urine) achieves the effect of odor isolation, but the effect is still limited. There is also a valve body and a floating ball design to block odors. The valve body is a single piece design. The floating sphere is also based on the principle of specific gravity to achieve the effect of odor isolation, but there is room for improvement. In general, there is still room for improvement in isolation of odors for the general drainage holes and the drainage holes of traditional and water-free urinals.

In view of the above-mentioned problems, the main purpose of the present invention is to provide a drainage device, which is applied to the drainage hole, and the novel structural design of the drainage valve solves the problem of preventing the odor of the conventional drainage hole.

Refer to Figure 1, Figure 2 and Figure 3. The liquid drain device 1 of this embodiment can be applied to the drain hole 9 and can be a drain hole in a bathroom or a kitchen. This embodiment uses the drain hole 9 of a urinal as an example. The liquid discharge device 1 of this embodiment includes a liquid discharge valve 10, a support frame 20, a cleaning unit 30 and a splash-proof unit 40.

Fig. 4A is a top view of the drain valve shown in Fig. 3, and Fig. 4B is a bottom view of the drain valve shown in Fig. 3. Please refer to Figs. 4A and 4B together. The drain valve 10 includes a body 11 and a plurality of membranes 12. The main body 11 has a channel 111, an upper surface 112 and a lower surface 113. The channel portion 111 has a cylindrical structure, so the channel portion 111 penetrates the main body 11. The lower surface 113 is opposite to the upper surface 112, that is, the upper surface 112 and the lower surface 113 are located on two opposite surfaces of the main body 11. In addition, the main body 11 further has a supporting portion 114 adjacent to the upper surface 112 and extending from the channel portion 111 to the outside to form a larger upper surface 112. In some embodiments, the carrying portion 114 can be used to be placed on the periphery of the drain hole 9 so that other parts of the body 11 and the film 12 can be accommodated in the drain hole 9 (not shown in the figure).

The plurality of thin films 12 are disposed inside the channel portion 111. Preferably, the number of the thin films 12 is three, and they have substantially the same size. As shown in FIG. 4A (top view), the three thin films 12 are evenly covered with the channel portion 111, and the gaps between the thin films 12 are in the shape of a three-pointed star. Each film 12 includes a fixed end 121 and a free end 122. Fig. 5A is a schematic cross-sectional view of the drain valve shown in Fig. 4A, please match the one shown in Fig. 5A. The free end 122 is located at an end opposite to the fixed end 121, that is, the fixed end 121 and the free end 122 are located at two opposite ends of the film 12 respectively. The fixed end 121 of this embodiment is directly connected to the upper surface 112 of the main body 11 and extends from the upper surface 112 to the lower surface 113. The free ends 122 of two adjacent films 12 are in contact with each other to form a sealing area S.

Specifically, the film 12 of this embodiment is designed to extend a distance at substantially the same level as the upper surface 112 (referred to as a flat top 123 in this embodiment), and then extend in a direction toward the lower surface 113 (referred to in this embodiment It is the bent portion 124), so that the free ends 122 of two adjacent films 12 can be in contact with each other to form a sealing area S and close the channel portion 111. In other words, each film 12 has a flat top portion 123 and a curved portion 124, the flat top portion 123 is connected to the fixed end 121, and the curved portion 124 is connected to the flat top portion 123 and extends to the lower surface 113 so that the free ends of the two adjacent films 12 122 are in contact with each other, and the cross-sections of two adjacent films 12 form a Y-shaped structure. Fig. 5B is a schematic diagram of the discharge valve shown in Fig. 5A used to indicate the size, please refer to Fig. 5B for collocation. Preferably, the thickness T1 of the fixed end 121 of this embodiment may be between 0.1 mm and 5 mm, and preferably may be 1 mm. The thickness T2 of the free end 122 may be between 0.1 mm and 3 mm, preferably 0.5 mm. In addition, the thickness of the curved portion 124 can be smaller than the thickness T1 of the flat top portion 123, so that the curved portion 124 can be bent in the direction of the lower surface 113 naturally.

Preferably, the height H1 of the main body 11 may be between 5 mm and 55 mm, preferably between 10 mm and 30 mm. The height H1 of the main body 11 in this embodiment is 10 mm as an example. By limiting the height of the main body 11, the drain valve 10 can be used not only in a water-free urinal, but also in a traditional urinal with a trap. In this embodiment, the free ends 122 of two adjacent films 12 only need to be in contact with each other. The sealing area S formed by the free ends 122 of two adjacent films 12 contacting each other can approach zero. Preferably, the ratio of the height H2 of the sealing area S to the height H1 of the body 11 can be between 0.01 and 0.75, so the height H2 of the sealing area S can be between 0.05 mm and 41.25 mm. Preferably, the height H2 of the sealing area S can be between 0.1 mm and 30 mm. That is, the height H2 of the contact area of the two adjacent films 12 can be designed to be between 0.1 mm and 30 mm, but it still needs to be adjusted according to the height H1 of the main body 11. For example, the height H1 of the body 11 of this embodiment is 10 mm, and the height H2 of the sealing area S may be between 0.01 mm and 7.5 mm. Preferably, the ratio of the height H2 of the sealing area S to the height H1 of the main body 11 may be 0.05. If the height H1 of the body 11 is 10 mm, the height H2 of the sealing area S may be 0.5 mm.

In addition, the film 12 of this embodiment is made of elastic material, such as but not limited to rubber, silicone, plastic, latex, foamed plastic, leather and other elastic materials. Due to the characteristics of the elastic material, when liquid (such as urine) flows to the drain valve 10, the flat top 123 of the film 12 carries the liquid until the weight of the liquid is sufficient to open the closed sealing area S. In other words, the free ends 122 of the two adjacent membranes 12 are separated, so that the liquid can flow to the other side of the drain valve 10 (ie, the lower surface 113 of the body 11) and be discharged from the drain hole 9. After the liquid flows out from the drain valve 10, the film 12 can also return to the closed state of the sealing area S due to the characteristics of the elastic material. That is, the free end 122 is restored to the closed state in contact with the free end 122 of the adjacent film 12. Therefore, the odor after oxidation of urine can be prevented from escaping to the upper side of the drain valve 10 (the upper surface 112 of the main body 11), thereby achieving the effect of deodorization.

In addition, due to the material of the film 12, the structural features of the flat top 123 and the curved portion 124, and the aforementioned limitation of the preferred size, the sealing area S can be easily switched between the closed state and the open state. Convert between. Specifically, the aforementioned limitation of the preferred size enables the film 12 to separate the free ends 122 of two adjacent films 12 (in an open state) when the film 12 bears a small amount of liquid (urine). Moreover, through the material of the film 12 and the structure of the flat top 123 and the curved portion 124, the free end 122 can quickly rebound (return) to the original position (closed state) after the liquid is discharged. In other embodiments, the film 12 can also have other configurations, which will be described below.

Preferably, the main body 11 of this embodiment can be made of the aforementioned elastic material. The lower surface 113 of the main body 11 is attached to the ceramic surface of the water-free or flushing urinal. Due to the characteristics of its elastic material, the lower surface 113 is attached to the peripheral ceramic surface of the drain hole 9, causing the drain pipe or The odor of the trap will not escape from the connection. In addition, preferably, the thickness of the carrying portion 114 may be 1 mm to avoid water accumulation at the boundary between the main body 11 and the surrounding ceramics.

In this embodiment, the drain valve 10a has a body 11 and a plurality of thin films 12a. Since the structure of the main body 11 is the same as the previous embodiment, its component numbers are used. In addition, the connection relationship between the film 12a and the main body 11 of this embodiment can also refer to the foregoing description. In this embodiment, each film 12a has a bent portion 124a located between the fixed end 121a and the free end 122a. In other words, the fixed end 121a directly extends from the upper surface 112 of the main body 11 to the lower surface 113 to form a curved portion 124a, instead of having the flat top portion 123 as in the previous embodiment, and the cross-section of the adjacent two films 12a can be formed Similar to U-shaped structure. The curved portion 124a of the film 12a of this embodiment can carry a small amount of liquid (urine). The weight of the liquid separates the free ends 122a of the two adjacent films 12 (the sealing area S is in an open state) for the liquid to flow to the drain. The other side of the liquid valve 10a. After the liquid flows out from the drain valve 10a, the film 12a can also restore the free end 122a to its original position (the sealing area S is in a closed state) by virtue of the elastic material and the structure of the bent portion 124a.

FIG. 7 is a three-dimensional cross-sectional schematic diagram of the support frame shown in FIG. 3 installed on the drain valve. Please refer to FIG. 2, FIG. 3 and FIG. 7. The liquid discharge device 1 of this embodiment further includes a support frame 20 which is disposed on the carrying portion 114 of the main body 11 and located on the upper surface 112 of the main body 11. Specifically, the supporting portion 114 has a plurality of fixing holes 1141, the support frame 20 has a plurality of fixing portions 21, and the fixing portions 21 are respectively disposed in the fixing holes 1141. The fixing portion 21 of this embodiment is a columnar bracket structure that can be inserted into the fixing hole 1141, thereby fixing the support frame 20 to the drain valve 10 and is located on the upper surface 112.

FIG. 8A is a schematic diagram of the support frame 20a of another example of the present invention, and FIG. 8B is a schematic diagram of the support frame 20a shown in FIG. 8A disposed on the drain valve 10 shown in FIG. 4, please refer to FIG. 8. Preferably, the support frame 20a further has a plurality of ribs 22a, and the number of the ribs 22a can be the same as the number of the film 12. The ribs 22a are respectively adjacent to the fixing portion 21a and inserted between the two adjacent films 12, that is, the ribs 22a are located between the two adjacent films 12 in the sealing area S. With the design of ribs 22a arranged between the films 12 of the sealing area S, a small amount of liquid (urine) can separate the free ends 122 of the two adjacent films 12 to open the closed sealing area S, which can improve the discharge The effect of liquid (urine).

Please refer to FIGS. 2 and 3 again. After the support frame 20 is assembled to the drain valve 10, the cleaning unit 30 and the splash-proof unit 40 can be arranged on the side of the support frame 20 opposite to the drain valve 10 in sequence. Specifically, the cleaning unit 30 can be arranged in the support frame 20, and the splash-proof unit 40 can be arranged above the support frame 20. In other words, the cleaning unit 30 is disposed on the upper surface 112 of the main body 11, and the splash-proof unit 40 covers the cleaning unit 30. There are gaps between the support frame 20, the cleaning unit 30 and the splash-proof unit 40 and the body 11, so that the liquid can directly flow into the drain valve 10 to avoid accumulation on the outside of the drain valve 10, and the liquid can be drained through the drain valve 10. Into the drain hole 9.

The splash-proof unit 40 has a plurality of microstructures 41 and openings 42. The microstructure 41 is disposed on the outer surface of the splash-proof unit 40 so that the outer surface of the splash-proof unit 40 forms an uneven surface. When the liquid (urine) rebounds (splashes), the uneven surface can slow down the rebound (splash) of the liquid, or reduce the scope of the liquid rebound (splash), thereby achieving the effect of splashing prevention and maintaining urination The cleaning of the wall of the bucket indirectly achieves the deodorant effect. In addition, the scope of liquid rebound (splash) is reduced, so that the user can be closer to the urinal when going to the toilet, thereby improving the problem of urine dripping to the outside of the urinal. For example, the microstructure 41 of this embodiment is a villi columnar body. When liquid (urine) is splashed, it can be bounced (splashed) again by the adjacent microstructure 41 (villi columnar body) to the opening 42. It flows out to the drain valve 10 through the opening 42 so as to achieve the effect of splash prevention. In other embodiments, the microstructure 41 may also be a linear structure that is twisted and wound in multiple numbers to form an uneven surface, which can also achieve a splash-proof effect.

Preferably, the splash-proof unit 40 can also be designed as a colored element, and the color of the splash-proof unit 40 can be different from the color of the urinal (usually white), and preferably can be blue, which is generally considered to have a sense of cleanliness. Color, or green representing energy saving and environmental protection, or made into an appearance or graphic similar to the earth (or other signs with energy saving and environmental protection meaning). When the user is going to the toilet, the splash-proof unit 40 can be aligned to maintain the cleanliness of the inner wall of the urinal.

Liquid (urine) can flow through the opening 42 of the splash-proof unit 40 to the cleaning unit 30 below. In this embodiment, the cleaning unit 30 may be a bio-enzyme cleaner. After the cleaning unit 30 comes into contact with the urine, it can decompose the organic molecules (the source of odor) in the urine to achieve the effect of cleaning and deodorizing. In other embodiments, the cleaning unit 30 can also be other cleaning agents with cleaning functions or effects, and the present invention is not limited.

It should be noted that the drain valve 10 can achieve the deodorizing effect. Preferably, the cleaning unit 30 and/or the splash-proof unit 40 can be configured to further achieve better deodorization and cleaning effects.

In summary, according to the present invention, the drain device applied to the drain hole includes a drain valve. The drain valve includes a body and a plurality of membranes, and the fixed ends of the membranes are connected to the upper surface of the body and extend from the upper surface to the lower surface. The free end is located at an end opposite to the fixed end, and the free ends of two adjacent films are in contact with each other to form a sealed area. When liquid (such as urine) flows to the drain valve, the weight of the liquid opens the closed sealing area to separate the free ends of the two adjacent membranes, and the liquid can flow to the other side of the drain valve and drain itself孔出。 Hole discharge. When the liquid flows out from the drain valve, the free end of the film returns to a closed state in contact with the free end of the adjacent film. Therefore, the odor after oxidation of the urine can be prevented from escaping to the upper side of the drain valve, thereby achieving the effect of deodorization. In addition, with the installation of the drain valve, the evaporation of the water (water seal) in the trap can be reduced to avoid the odor caused by long-term use.
