Description

Technical Field

[0001] The invention relates to the technical field of kitchen and bathroom accessories, and in particular to an odor isolation device and a urinal. Background Art

[0002] Urinals are usually hung on the wall, and there are two main drainage methods: wall drainage and floor drainage. In the wall drainage method, the drainage outlet is set on the wall where the urinal body is located, and the drainage outlet is blocked by the urinal, which has a beautiful and simple appearance. However, the distance between the main body of the urinal that uses the wall drainage method for drainage is short and the internal space is narrow. Although there are solutions in the prior art to set ordinary S-shaped water traps or P-shaped water traps in wall-drained urinals, they will cause the problem of the urinal body being too large. How to install the water trap in the narrow space between the urinal body and the wall while ensuring the normal volume of the urinal body is an urgent problem to be solved. Summary of the invention

[0003] The object of the present invention is to overcome the above-mentioned defects or problems existing in the background technology and to provide an odor isolation device and a urinal, wherein the odor isolation device is small in size and can be directly installed on the sewage pipe of the urinal in the narrow space between the urinal and the wall. When in use, a water seal can be formed to achieve effective odor isolation.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] A odor-isolating device is provided with a water inlet and a water outlet which are interconnected, a water trap is provided between the water inlet and the water outlet, and the plane where the water trap is located is perpendicular to the direction of the water outlet.

[0006] Furthermore, the odor-isolating device is provided with two water traps with opposite bending directions to form water seal areas in different installation directions.

[0007] Furthermore, a water trap of the odor-isolating device is bent in a direction toward another water trap.

[0008] Furthermore, the odor isolation device is provided with a first interface and a second interface for connecting to an external pipe, and the first interface and the second interface are both connected to the water inlet; the orientation of the first interface is parallel to the orientation of the water outlet, and the orientation of the second interface is perpendicular to the orientation of the water outlet; and it also includes at least one sealing cover, and when one of the first interface or the second interface is connected to an external pipe, the sealing cover seals the other one.

[0009] In addition, the present invention also provides a urinal, which is provided with a sewage pipe, and an odor isolation device as described in any one of the above items is installed on the sewage pipe.

[0010] From the above description of the present invention, it can be seen that compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. Form a bend in the direction of the water trap and the water outlet of the odor isolation device, thereby reducing the length of the odor isolation device in one direction and appropriately increasing the length of the odor isolation device in the other direction. During installation, the direction of reducing the length corresponds to the direction between the urinal and the wall, so that the odor isolation device can be installed in the narrow space between the urinal and the wall and achieve better odor isolation effect.

[0012] 2. The odor-isolating device is provided with two water traps with opposite bending directions, so that after the odor-isolating device is installed, as long as one water trap is kept downward, the odor-isolating function can be achieved. If the odor-isolating device is installed upside down, odor-isolating cannot be achieved.

[0013] 3. The bending direction of one water trap is toward the other water trap, so that the odor isolation device as a whole can form a ring-like shape, thereby reducing the axial length of the odor isolation device in the left-right direction.

[0014] 4. The first interface and the second interface are provided, and the directions of the two interfaces are arranged in a vertical relationship, so that the odor-isolating device can be applied to both wall-flush urinals and floor-flush urinals, thereby expanding the scope of use.

[0015] 5. A sealing cover is provided. When the first interface or the second interface is connected to the pipe of the urinal, the other interface which is not connected to the pipe of the urinal can be sealed, thereby ensuring the overall sealing of the odor isolation device.

[0029] In the claims, description and drawings of the present invention, if the terms "include", "have" and their variations are used, they are intended to mean "including but not limited to".

[0030] See also Figure 1 , Figure 1 The structure diagram of a odor isolation device 10 provided by the present invention is shown. Figure 2 or Figure 3 As shown, in the odor isolation device 10, a water inlet 11 and a water outlet 12 are provided which are interconnected, a water trap is provided between the water inlet 11 and the water outlet 12, and a plane where the water trap is located is perpendicular to the direction of the water outlet 12.

[0031] The plane where the water trap is located refers to the plane defined by the two arms when the two arms of the water trap are parallel to each other.

[0032] Furthermore, the odor-isolating device 10 is provided with two water traps with opposite bending directions to form water seal areas in different installation directions.

[0033] Specifically, in this embodiment, the odor isolation device 10 has the following Figure 1 The first water trap 13 and the second water trap 14 are shown. The odor isolation device 10 provided in this embodiment has a shell, the main part of which is a circular or elliptical pipe with two bends. The two bends can be regarded as one end of a U-shaped tube connected to one end of another U-shaped tube to form a connecting structure inside. The water inlet 11 is arranged at one end of one of the U-shaped tubes, and the water outlet 12 is arranged at one end of the other U-shaped tube, so that the water inlet 11 and the water outlet 12 are connected through the bend. At the same time, the two bends form the first water trap 12 and the second water trap 14. In this embodiment, the first water trap 13 refers to the bend near the water inlet 11, and the second water trap 14 refers to the bend near the water outlet 12.

[0034] In this embodiment, the bending directions of the first water trap 13 and the second water trap 14 are opposite to each other. Figure 3 Taking the direction as an example, the bending direction of the first water trap 13 is downward, and the bending direction of the second water trap 14 is upward. During installation, it is sufficient to keep the first water trap 13 or the second water trap 14 in a vertical direction.

[0035] Preferably, the bending direction of one water trap of the odor isolation device 10 is toward another water trap, and its specific structure is as follows: Figure 3As shown, the second water trap 14 is the bending body, and its bending direction is toward the position where the first water trap 13 is located. One arm of the first water trap 13 is connected to the other arm of the second water trap 14, and the other arm of the second water trap 14 is bent toward the position where the other arm of the first water trap 13 is located, so that the first water trap 13 and the second water trap 14 form a spiral-like shape that expands outward from the center, and this shape can have a smaller volume. At the same time, this design with two water traps can also make the water flow of the odor isolation device 10 have a buffer zone, which can prevent water from flowing directly from the water outlet 12, and ensure that the odor isolation device 10 can form an effective water seal.

[0036] Of course, in other embodiments, the bending direction of one water trap of the odor isolation device 10 can be away from the other water trap, thereby forming an S-shaped structure, but the length of this structure in the left and right directions is longer than that of the above-mentioned embodiment. When the space between the urinal and the wall is relatively small, it is less inconvenient than the above-mentioned embodiment.

[0037] In addition, the odor isolation device 10 is also provided with a first interface 21 and a second interface 22 for connecting to an external pipe. The first interface 21 and the second interface 22 are both connected to the water inlet 11. The direction of the first interface 21 is parallel to the direction of the water outlet 12, and the direction of the second interface 22 is perpendicular to the direction of the water outlet 12.

[0038] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in addition to the bent pipe, which is the main part of the odor isolation device 10, there are two interfaces connected to the water inlet 11 on the bent pipe, namely the first interface 21 and the second interface 22. The two interfaces are connected to the water inlet 11 from two mutually perpendicular directions, and threads are provided on the outer edges of the two interfaces for connecting to external pipes.

[0039] The present invention further provides a urinal, which includes a sewage pipe, and the odor isolation device 10 provided in this embodiment is installed on the sewage pipe.

[0040] The above-mentioned external pipe refers to the sewage pipe on the urinal. The specific installation status is as follows: Figure 5 and Figure 6 As shown, the states of being installed on a wall-mounted urinal 30 and a floor-mounted urinal 40 are respectively shown.

[0041] In an installation instance, such as Figure 5As shown, the odor-isolating device 10 is connected to the sewage pipe of the wall-mounted urinal 30 through the first interface 21. Since the sewage pipe here is close to the bottom of the wall-mounted urinal 30, the second interface 22 is directed downward, and the second water trap 14 is used as the water storage part. After the water flows through the first interface 21 and enters the water inlet 11, it passes through the first water trap 13, then passes through the second water trap 14, and then flows out through the water outlet 12. At the same time, a water seal can be formed at the second water trap 14 to isolate the odor. At this time, the second interface 22 can be sealed with a cover to prevent water from leaking from here. Of course, if there is a sufficient height between the wall-mounted urinal 30 and the wall, after the odor-isolating device 10 is installed on the sewage pipe of the wall-mounted urinal 30, the direction of its second interface 22 can also be directed upward, and at this time the water storage part is the first water trap 13.

[0042] In another installation instance, such as Figure 6 As shown, the odor-isolating device 10 is connected to the sewage pipe of the floor urinal 40 through the second interface 22, and the first water trap 13 is used as the water storage part. After the water flows through the second interface 22 and enters the water inlet 11, it passes through the first water trap 13 position, and then passes through the second water trap 14 and is discharged through the water outlet 12. A water seal can be formed at the first water trap 13 position to isolate odor. At this time, the first interface 21 can be sealed with the cover 23 to prevent water from leaking out from here.

[0043] The odor-isolating device 10 provided by the present invention can be made of plastic material by an integrated molding method due to its small size, and can be used as a urinal accessory. It can be suitable for wall-mounted or floor-mounted urinals. Consumers do not need to confirm which urinal they need to adapt when purchasing, and can use the odor-isolating device provided by the present invention, thereby providing convenience for consumers.

[0044] The odor-isolating device 10 provided by the present invention reduces the volume of the odor-isolating device 10 by forming a perpendicular relationship between the plane where the water trap is located and the direction of the water outlet 12, so that the odor-isolating device 10 can be installed in the narrow space between the urinal and the wall.

[0045] The description of the above specification and embodiments is used to explain the protection scope of the present invention, but does not constitute a limitation on the protection scope of the present invention. Through the enlightenment of the present invention or the above embodiments, ordinary technicians in this field can obtain modifications, equivalent substitutions or other improvements to the embodiments of the present invention or part of the technical features thereof through logical analysis, reasoning or limited experiments, which should be included in the protection scope of the present invention.
