Description

Drainage device

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

Generally speaking, the drain holes in the bathroom or kitchen are open. In order to prevent the odor of the drainage channel from escaping, the connected drainage pipe will be curved. This curved structure is also known as a trap (S-trap, or P-trap). Building regulations in many countries and regions require that the drainage structure of bathrooms or kitchens must have water traps to prevent the backflow of biogas or other toxic gases, which will 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 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 stored water (also known as water seal) in the water trap has a physical phenomenon of being evaporated, so the water seal will disappear when it is not used for a long time, and there will be odor and biogas backflow.

In addition, traditional urinals (or urinals) are flushed frequently to keep the urinal clean and dilute the urine and its residual odor. Similarly, in order to avoid the odor of the drainage channel, a water trap is also installed, but the upper end of the water trap to the drainage port of the urinal will still produce odor due to the residue of urine. In addition, in order to achieve the purpose of environmental protection and water saving, a flush-free urinal has been launched on the market. The flush-free urinal is equipped with an odor-isolating filter element, which has an oil-based isolating liquid inside, and achieves the effect of isolating odors through the principle that the specific gravity of the liquid (urine) is heavier, 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 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 the odor isolation of general drainage holes and drainage holes of traditional and water-free urinals.

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

In order to achieve the above-mentioned object, the present invention provides a drainage device, which is applied to a drainage hole. The drain device includes a drain valve, which includes a body and a plurality of membranes. The main body has a channel part, an upper surface and a lower surface, the channel part penetrates the main body, and the lower surface is opposite to the upper surface. The thin film is provided inside the channel portion. Each of the 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 one end opposite to the fixed end, and the free ends of two adjacent thin films are in contact with each other.

According to an embodiment of the present invention, the number of the films is three.

According to an embodiment of the present invention, the thickness of the fixed end is between 0.1 mm and 5 mm, and the thickness of the free end is between 0.1 mm and 3 mm.

According to an embodiment of the present invention, the height of the body is between 5 mm and 55 mm.

According to an embodiment of the present invention, the free ends of two adjacent films are in contact with 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, and 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 located between the fixed end and the free end.

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

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

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

According to an embodiment of the present invention, the bearing portion has a plurality of fixing holes, the support frame has a plurality of fixing portions, and the fixing portions 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 inserted between the two adjacent films.

According to an embodiment of the present invention, the liquid draining device further includes a cleaning unit disposed on the upper surface of the main body.

According to an embodiment of the present invention, the liquid draining device further includes a splash-proof unit covering the cleaning unit. The splash-proof unit has a plurality of microstructures and is arranged on an outer surface of the splash-proof unit.

According to an embodiment of the present invention, the liquid draining device further includes a support frame disposed on the bearing portion and located on the upper surface of the body. The cleaning unit is arranged in the support frame, and the splash-proof unit is arranged above the support frame.

Based on the above, according to the present invention, the drainage device applied to the drainage hole includes a drainage valve. The drain valve includes a body and a plurality of membranes, and 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 one end opposite to the fixed end, and the free ends of two adjacent films are in contact with each other to form a sealing area. When the liquid (such as urine) flows to the drain valve, the closed sealing area is opened by the weight of the liquid, so that the free ends of the two adjacent membranes are separated, and the liquid can flow to the other side of the drain valve and self-drain hole discharge. When the liquid flows out from 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 of the oxidized urine can be isolated and emitted to the upper side of the drain valve, thereby achieving the effect of deodorization.

In addition, the deodorization effect is effectively achieved by the drain valve, and when applied to the urinal, the water for cleaning can be greatly reduced without flushing each time, that is, the consumption of water for cleaning can be effectively reduced.

This embodiment is described by taking the drain hole 9 applied to a urinal as an example. The drain device 1 of this embodiment includes a drain 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 FIGS. 4A and 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 through 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 body 11 . In addition, the main body 11 further has a bearing portion 114 adjacent to the upper surface 112 and extending 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 drainage hole 9 so that other parts of the body 11 and the membrane 12 can be accommodated in the drainage hole 9 (not shown).

A 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 equally covered with the channel portion 111 , and the gap between the films 12 is 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 , which is shown in conjunction with FIG. 5A . The free end 122 is located at one 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 in the direction of the lower surface 113 (called a flat top 123 in this embodiment) after extending for a distance at substantially the same level as the upper surface 112 (referred to as a flat top 123 in this embodiment). The free ends 122 of the adjacent two films 12 can be in contact with each other, so as to form the 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 , and the curved portion 124 is connected to the flat top 123 and extends toward the lower surface 113 , thereby allowing the free ends of 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 of the drain valve shown in FIG. 5A for marking the size, please refer to FIG. 5B together. 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 curved portion 124 can be smaller than the thickness T1 of the flat top portion 123 , so that the curved portion 124 can be naturally bent in the direction of 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 main body 11 in this embodiment is 10 mm as an example for illustration. By limiting the height of the body 11 , the drain valve 10 can be applied not only to a water-free urinal, but also to a traditional urinal with a water trap. In this embodiment, the free ends 122 of two adjacent thin films 12 only need to be in contact with each other. The sealing area S formed by the contact between the free ends 122 of two adjacent thin films 12 can 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 the two adjacent films 12 can be designed to be between 0.1 mm and 30 mm, but still needs to be adjusted according to the height H1 of the body 11 . For example, the height H1 of the body 11 in 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 an elastic material, such as but not limited to rubber, silicone, plastic, latex, foamed plastic, leather and other elastic materials. Due to the properties 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 adjacent two 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 main body 11 ) and be drained from the drain hole 9 . When the liquid flows out from the drain valve 10 , the membrane 12 can also return to the closed state of the sealing area S due to the properties 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, the odor of the oxidized urine can be isolated from being emitted 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 above-mentioned limitation of the preferred size, the sealing area S can be more easily in the closed state and the open state. conversion between. Specifically, the above-mentioned limitation of the preferred size enables the film 12 to separate the free ends 122 (open state) of two adjacent films 12 when carrying a small amount of liquid (urine). In addition, through the material of the membrane 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 may 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 flush-type urinal, and because of the characteristics of the elastic material, the lower surface 113 is attached to the ceramic surface around the drainage hole 9, so that the drainage pipeline or The odor from the trap will not escape from the connection. In addition, preferably, the thickness of the bearing portion 114 can be 1 mm, so as to avoid the situation of water accumulation at the interface between the main body 11 and the surrounding ceramics.
