Description

Discharge device

This creation relates to a liquid drainage device, especially a liquid drainage device applied to a drain hole.

Generally speaking, the drainage holes in the bathroom or kitchen are open. In order to avoid the odor of the drain, the connected drain pipe is made into a curved type. This curved structure is also called S-trap or P-trap. Building regulations in many countries and regions require that the drainage structure of the bathroom or kitchen must have a water trap to prevent the backflow of biogas or other toxic gases, which in turn can cause harmful effects on the human body. In order to prevent foreign matter from blocking the drainage hole, a drainage filter cover is generally provided, but it must have a large-diameter diversion hole 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 storage (also known as water seal) in the water trap has the physical phenomenon of being evaporated, so the water seal will disappear when there is no long-term use, and there will be odor 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. In order to avoid the odor of the drainage channel, a trap is also provided, but the upper end of the trap to the drain port of the urinal will still produce odor due to the residual urine. In addition, in order to achieve environmental protection and save water resources, flush-free urinals have been introduced on the market. The flush-free urinal is based on the principle of setting up a odor-removing filter element, which has an oily insulating liquid inside, and the specific gravity of the liquid (urine) is heavier to achieve the effect of isolating odor, but the effect is still limited. In addition, the design of the valve body and the floating sphere is used to block the odor. The valve body is a single-piece design. The floating sphere is also the principle of specific gravity to achieve the effect of isolating the odor, but there is room for improvement. In general, there is still room for improvement in 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 this creation is to provide a drainage device, which is applied to the drainage hole, and through the novel structure design of the drainage valve, to solve the problem of the conventional drainage hole in blocking odor.

In order to achieve the above purpose, the present invention provides a drainage device, which is applied to a drainage hole. The liquid discharge device includes a liquid discharge valve, which includes a body and a plurality of films. The body has a channel portion, an upper surface and a lower surface, the channel portion penetrates the body, and the lower surface is opposite to the upper surface. The film is provided inside the channel part. Each of these films includes a fixed end and a free end. The fixed end is connected to the upper surface of the body and extends from the upper surface to the lower surface. The free end is located at the end opposite to the fixed end, and the free ends of two adjacent films contact each other.

According to an embodiment of the present invention, the free ends of two adjacent films contact each other to form a sealing area, and the height of the sealing area is between 0.1 mm and 30 mm.

According to an embodiment of the present invention, the ratio of the height of the sealing area to the height of the body is between 0.01 and 0.75.

According to an embodiment of the present invention, each of the films has a flat top and a curved portion, the flat top is connected to the fixed end, the curved portion is connected to the flat top, and extends toward the lower surface.

According to an embodiment of the present invention, each of the films has a bent portion, which is located between the fixed end and the free end.

According to an embodiment of the present invention, the body further has a bearing portion, which is adjacent to the upper surface and extends outward from the channel portion.

According to an embodiment of the present creation, the bearing portion is placed in the drainage hole.

According to an embodiment of the present invention, the liquid discharge device further includes a support frame, which is disposed on the bearing portion and located on the upper surface of the body.

According to an embodiment of the present invention, the bearing part has a plurality of fixing holes, the support frame has a plurality of fixing parts, and the fixing parts are respectively disposed in the fixing holes.

According to an embodiment of the present invention, the support frame further has a plurality of ribs, which are respectively adjacent to the fixing portions and interposed between two adjacent films.

The cleaning unit is arranged in the support frame, and the splash prevention unit is arranged above the support frame.

As mentioned above, the drainage device applied to the drainage hole according to this creation includes the drainage valve. The drain valve includes a body and a plurality of membranes. The fixed end of the membrane is connected to the upper surface of the body and extends from the upper surface to the lower surface. The free end is located at the end opposite to the fixed end, and the free ends of two adjacent films contact each other to form a sealed area. When liquid (such as urine) flows to the drain valve, the closed seal area is opened by the weight of the liquid to separate the free ends of the two adjacent films, and the liquid can flow to the other side of the drain valve and drain itself The hole is discharged. When the liquid flows out of the drain valve, the free end of the membrane returns to the closed state in contact with the free end of the adjacent membrane. Therefore, the odor after the urine is oxidized can be prevented from being emitted to the upper side of the drain valve, thereby achieving the effect of deodorization.

In addition, the discharge valve can effectively achieve the deodorizing effect. When used in the urinal, there is no need to flush the water every time, which can greatly reduce the cleaning water, that is, can effectively reduce the consumption of cleaning water.

Refer to Figure 1, Figure 2, and Figure 3. The liquid drainage device 1 of this embodiment can be applied to the drainage hole 9 and can be a drainage hole of a bathroom or kitchen. In this embodiment, the drainage hole 9 applied to the urinal is used as an example for description. 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.

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 FIG. 4A and FIG. 4B together. The drain valve 10 includes a body 11 and a plurality of membranes 12. The body 11 has a channel portion 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 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 body 11. Furthermore, the body 11 further has a bearing portion 114 adjacent to the upper surface 112 and extends outward from the channel portion 111 to form a larger upper surface 112. In some embodiments, the bearing portion 114 can 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).

The plurality of thin films 12 are disposed inside the channel portion 111. Preferably, the number of thin films 12 is three and has substantially the same size. As shown in FIG. 4A (top view), the three films 12 are evenly distributed over the channel portion 111, and the gap between the films 12 takes 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 with 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 opposite ends of the film 12, respectively. In this embodiment, the fixed end 121 is directly connected to the upper surface 112 of the body 11 and extends from the upper surface 112 toward the lower surface 113. The free ends 122 of two adjacent films 12 are in contact with each other to form a sealed area S.

Specifically, the film 12 of this embodiment is designed to extend at a substantially same horizontal distance as the upper surface 112 (referred to as a flat top 123 in this embodiment), and extend in the direction of the lower surface 113 (referred to in this embodiment) For the curved portion 124), the free ends 122 of the 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 123 and a curved portion 124, the flat top 123 is connected to the fixed end 121, the curved portion 124 is connected to the flat top 123, and extends toward 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 the two adjacent thin films 12 form a Y-shaped structure. FIG. 5B is a schematic diagram showing the size of the drain valve shown in FIG. 5A. Please refer to FIG. 5B for reference. Preferably, the thickness T1 of the fixed end 121 in this embodiment may be between 0.1 mm and 5 mm, preferably 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 bent portion 124 may be smaller than the thickness T1 of the flat top portion 123, so that the bent portion 124 can be bent naturally toward the lower surface 113.

Preferably, the height H1 of the body 11 may be between 5 mm and 55 mm, preferably between 10 mm and 30 mm. The height H1 of the body 11 of this embodiment is illustrated by taking 10 mm as an example. By limiting the height of the body 11, the drain valve 10 can be used not only in water-free urinals, but also in traditional urinals with traps. In this embodiment, the free ends 122 of two adjacent films 12 only need to contact each other. The sealing area S formed by the free ends 122 of two adjacent films 12 contacting each other may approach zero. Preferably, the ratio of the height H2 of the sealing area S to the height H1 of the body 11 may be between 0.01 and 0.75, so the height H2 of the sealing area S may be between 0.05 mm and 41.25 mm. Preferably, the height H2 of the sealing area S may be between 0.1 mm and 30 mm. That is, the height H2 of the contact area between 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 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 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 elastic materials such as rubber, silicone, plastic, latex, foamed plastic, leather goods and so on. Due to the characteristics of the elastic material, when liquid (eg, urine) flows to the drain valve 10, the flat top 123 of the membrane 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 films 12 are separated so that the liquid can flow to the other side of the drain valve 10 (that is, the lower surface 113 of the body 11) and be discharged from the drain hole 9. After the liquid flows out of the drain valve 10, the membrane 12 can also return to the closed state of the sealing area S by the characteristics of the elastic material. That is, the free end 122 is returned to the closed state in contact with the free end 122 of the adjacent film 12. Therefore, it is possible to isolate the odor after the urine is oxidized to the upper side of the drain valve 10 (the upper surface 112 of the body 11 ), thereby achieving an anti-odor effect.

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

Preferably, the body 11 of this embodiment can be composed of the aforementioned elastic material. The lower surface 113 of the body 11 is attached to the ceramic surface of the waterless or flushing urinal, and due to the characteristics of its elastic material, the lower surface 113 and the peripheral ceramic surface of the drain hole 9 are attached to each other, resulting in the drainage pipe or The odor of the trap will not escape from the connection. In addition, preferably, the thickness of the bearing portion 114 may be 1 millimeter to avoid water accumulation at the junction between the body 11 and the surrounding ceramic.

FIG. 6 is a schematic cross-sectional view of another embodiment of the created drain valve 10a, please refer to FIG. 6. In this embodiment, the drain valve 10a has a body 11 and a plurality of films 12a. Since the structure of the body 11 is the same as that of the foregoing embodiment, the component reference numerals are used. In addition, for the connection relationship between the film 12a and the body 11 of this embodiment, reference may also be made to the foregoing description. In this embodiment, each film 12a has a bent portion 124a, which is located between the fixed end 121a and the free end 122a. In other words, the fixed end 121a extends directly from the upper surface 112 to the lower surface 113 of the body 11 to form a curved portion 124a without the flat top portion 123 as in the previous embodiment, and allows the cross-section of the two adjacent films 12a to be formed U-shaped structure. The curved portion 124a of the film 12a of this embodiment can carry a small amount of liquid (urine), and the free ends 122a of the two adjacent films 12 are separated by the weight of the liquid (the sealing area S is in an open state) for the liquid to flow to the discharge The other side of the liquid valve 10a. After the liquid flows out of the drain valve 10a, the membrane 12a can also restore the free end 122a to its original position (the sealing area S is in a closed state) by the characteristics of the elastic material and the structure of the bent portion 124a.

FIG. 7 is a perspective cross-sectional schematic view of the support frame shown in FIG. 3 disposed on the drain valve, please refer to FIGS. 2, 3 and 7. The liquid discharging device 1 of this embodiment further includes a support frame 20, which is disposed on the bearing portion 114 of the body 11 and located on the upper surface 112 of the 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 provided in the fixing holes 1141. The fixing portion 21 of this embodiment is a column-shaped bracket structure, which can be inserted into the fixing hole 1141, thereby fixing the support frame 20 to the drain valve 10 and located on the upper surface 112.

FIG. 8A is a schematic diagram of a support frame 20a of another example of creation, and FIG. 8B is a schematic diagram of the support frame 20a shown in FIG. 8A provided in 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 may be the same as the number of the film 12. The ribs 22a are respectively adjacent to the fixing portion 21a and interposed 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 the ribs 22a between the membranes 12 in the sealing area S, a small amount of liquid (urine) can separate the free ends 122 of the two adjacent membranes 12 to open the closed sealing area S and 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 sequentially arranged on the side of the support frame 20 opposite to the drain valve 10. Specifically, the cleaning unit 30 may be disposed in the support frame 20, and the splash prevention unit 40 may be disposed above the support frame 20. In other words, the cleaning unit 30 is disposed on the upper surface 112 of the body 11, and the splash prevention 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 discharged 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) bounces (splashes), the uneven surface can slow down the liquid bounce (splash), or reduce the range of the liquid bounce (splash), so as to achieve the effect of splash-proof, and maintain urination The cleanliness of the wall of the bucket indirectly achieves the deodorizing effect. In addition, the range 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 droplets leaking to the outside of the urinal. For example, the microstructure 41 of this embodiment is a villi columnar body. When the liquid (urine) is splashed, it can be rebounded (splashed) by the adjacent microstructure 41 (villi columnar body) to the opening 42 to It flows out to the drain valve 10 through the opening 42 to achieve the effect of splash prevention. In other embodiments, the microstructure 41 may also be a plurality of linear structures bent and wound to form an uneven surface, which can also achieve the effect of preventing splashing.

Preferably, the splash-proof unit 40 can also be designed as a colored component, and the color of the splash-proof unit 40 can be different from the color of the urinal (generally white), preferably blue, which is generally considered to have a clean feeling Color, or green representing energy conservation and environmental protection, or made to resemble the earth (or other signs with the meaning of energy conservation and environmental protection) or graphics. When users use the toilet, they can aim at the splash-proof unit 40 to keep the inner wall surface of the urinal clean.

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

It should be noted that the drain valve 10 can achieve an anti-odor 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, the liquid discharge device applied to the drainage hole according to this creation includes a liquid discharge valve. The drain valve includes a body and a plurality of membranes. The fixed end of the membrane is connected to the upper surface of the body and extends from the upper surface to the lower surface. The free end is located at the end opposite to the fixed end, and the free ends of two adjacent films contact each other to form a sealed area. When liquid (such as urine) flows to the drain valve, the closed seal area is opened by the weight of the liquid to separate the free ends of the two adjacent films, and the liquid can flow to the other side of the drain valve and drain itself The hole is discharged. When the liquid flows out of the drain valve, the free end of the membrane returns to the closed state in contact with the free end of the adjacent membrane. Therefore, the odor after the urine is oxidized can be prevented from being emitted to the upper side of the drain valve, thereby achieving the effect of deodorization. In addition, through the installation of the drain valve, the evaporation of the water storage (water seal) in the trap can be reduced to avoid the situation of emitting odor due to long-term unused.
