This application claims the priority of China patent application No. 202321748651.X filed on Jul. 4, 2023, entitled “Self-overflow drainage joint”, and the entire contents, including the amendments therein, of which are all incorporated herein by reference.
The present invention relates to the technical field of drainer, in particular to a self-overflow drainage joint.
A drainer refers to the drainage device placed in the drainer of bathtub and basin, which is used to drain the water in the bathtub and basin into the drainer. It has the functions of draining and storing water. The existing drainers can be divided into bouncing-type drainers, flip-type drainers and lifting-type drainers according to types. According to the material, drainers can be divided into copper drainers, stainless steel drainers, plastic drainers, etc. According to the use, drainers can be divided into bathtub drainers, basin drainers and so on.
The sink drainer is something we use every day, which is widely used in every household. According to the shape and structure of the drainer, it can be divided into drainer part and overflow pipe part. In the prior art, for example “Waste water outlet unit” disclosed in U.S. Pat. No. 8,813,273, and “SEWEROVERFLOWRELIEFDEVICE” disclosed in U.S. Patent. No. 20100108159A1, the drainage function is assisted by arranging a drainage connector on the drainer, but it does not have the structure of being connected to an overflow pipe.
In the prior art, such as “press-type overflow drainage device for water container” disclosed in U.S. Pat. No. 11,441,301, it provides a pressure overflow drainage device for a water container with a water outlet and an overflow port, but the existing drainer connectors are usually without overflow holes. Therefore, it is necessary to choose a drainer with or without overflow holes. The choice of a drainer depends on whether the basin has overflow holes. The drainer with overflow holes can be used in the basin without overflow holes, and the drainer without overflow holes can also be used in the basin with overflow holes. In different use environments, it is necessary to use the drainer with overflow holes or the drainer without overflow holes, which is limited in use and not universal enough.
Considering the high cost of directly replacing the drainer, it is necessary to provide a self-overflow drainage joint, which can be suitable for different drainers with or without overflow holes. When the joint body is connected with the drainer with overflow holes, the water overflowed by the overflow holes can overflow; when the joint body is connected with a drainer without an overflow port, the joint body drains water normally, and the manufacturing cost is low and the universality is high.
The present invention provides a self-overflow drainage joint, which includes a joint body, wherein the joint body comprises a flow channel, a water inlet and a water outlet; an end of the joint body at the water inlet is matched and fixed with a drainer to form a combined state in which the drainer is communicated with the joint body; wherein, the end of the joint body at the water inlet is provided with an overflow area, and at least one overflow hole communicated with the flow channel is formed in the overflow area.
The present invention further provides a self-overflow drainage joint, which includes a joint body, wherein the joint body comprises a flow channel, a water inlet and a water outlet, wherein an end of the joint body at the water inlet is matched and fixed with a drainer to form a combined state in which the drainer is communicated with the joint body, wherein the end of the joint body at the water inlet is provided with an overflow area, and at least one overflow hole communicated with the flow channel is formed in the overflow area;
the joint body is provided with a mounting part which is matched and fixed with the drainer and a peripheral part located at a periphery of the mounting part, and the overflow area is formed between the peripheral part and the mounting part.
The present invention further provides a self-overflow drainage joint, which includes a joint body mounted to a drainer, the joint body comprising a flow channel communicated with a water inlet and a water outlet, wherein the joint body further comprises an overflow area formed on an outer wall of the joint body and an overflow hole communicated with the overflow area and the flow channel, and the overflow hole is opened in a shade area of the overflow area on the outer wall of the joint body.

As shown in
In some embodiments, a self-overflow drainage joint provided by the present invention comprises a joint body 1 mounted to a drainer, the joint body 1 comprises a flow channel 2 communicated with a water inlet 3 and a water outlet 4; the joint body 1 further comprises an overflow area 5 formed on the outer wall of the joint body 1 and an overflow hole 6 communicated with the overflow area 5 and the flow channel 2, and the overflow hole 6 is opened in the shade area of the overflow area 5 on the outer wall of the joint body 1. The inlet of the overflow area is provided with a sealing mechanism or universal/general-utility interface to adapt to different types of overflow pipes on the overflow outlet and to seal the overflow area when the overflow pipe is not connected.
The joint body 1 is provided with a mounting part 7 which is fixed with the drainer and a peripheral part 8 which is located at the periphery of the mounting part 7, and the overflow area 5 is formed between the peripheral part 8 and the mounting part 7. Whether it is a washbasin with an overflow port or a washbasin without an overflow port, the drainage joint with an overflow hole 6 can be used. When in use, the threaded part of the drainer is screwed with the mounting part 7, and if the washbasin does not have an overflow port, the fluid normally passes through the drainage joint, and the fluid is less likely to leak from the overflow hole 6 of the drainage joint. If the basin has an overflow port, part of the fluid higher than the water level line of the basin will enter the overflow area 5 and be discharged into the flow channel 2 through the overflow hole 6. In some embodiments (not shown in the figure), an opening and closing mechanism or a one-way valve is arranged on the overflow hole 6 to improve the influence of preventing overflow from flowing back, and the overflow hole 6 can be designed to be arranged in a plurality of different positions or with different apertures to control the amount of overflow water.
In some embodiments (not shown in the figure), the peripheral part 8 is provided with an interface which can be connected with a water pipe, and the interface is communicated with the overflow area 5, and is connected with the overflow drainage joint installed on the side wall of the sink through the overflow pipe. When the water is accumulated to a certain height to the overflow drain joint, it can flow from the through hole of the overflow head to the overflow area 5 along a connecting pipe assembly and finally be discharged through the flow passage 2. The flow rate of the overflow head of the present invention can be higher than the running water speed of the faucet; the connecting pipe assembly is divided into multiple sections, which can be easily disassembled and replaced. Compared with the design of connecting the filter drainage joint and overflow drainage joint with a whole hose, it is not necessary to replace the whole part, which is simple to install and disassemble, lower in cost and saves resources.
The mounting part 7 and the peripheral part 8 are integrally formed on the joint body 1, and the overflow hole 6 is opened at the bottom of the overflow area 5. In this embodiment, the drainage joint is integrally injection molded, which is convenient to manufacture and low in cost.
The bottoms of the mounting part 7 and the peripheral part 8 are connected into a whole through the linking part 9, which comprises a conical bottom wall 10 and a planar bottom wall 11 located in the overflow area 5. The ends of the conical bottom wall 10 and the planar bottom wall 11, which are far away from each other, re connected with the peripheral part 8 and the mounting part 7 respectively. The height of the end of the conical bottom wall 10 connected with the planar bottom wall 11 is lower than that of the end of the conical bottom wall 10 connected with the peripheral part 8, and the fluid can flow to the overflow hole 6 under the action of the conical bottom wall 10 after entering the overflow area 5.
The mounting part 7 is internally provided with a threaded mounting hole 12 which is threadedly matched with the drainer, so that the drainer and the drainage joint can be assembled more conveniently. In some embodiments (not shown in the figure), the drainer and the drainage joint can also be assembled in the form of clamping and plugging, and the threaded connection mode in the application is preferred.
A plurality of support plates 13 are arranged in the overflow area 5 at intervals along the circumferential direction, and the height of the support plates 13 is lower than that of the peripheral part 8 and a first gasket is placed on the support plate 13. In this embodiment, a height difference is formed between the support plate 13 and the peripheral part 8, and a space for placing the first gasket 14 can be formed. The first gasket 14 can be a plastic first gasket 14, a rubber first gasket 14, etc.; and a bowl-shaped second gasket 16 is also arranged on the first gaskets 14, and the second gasket 16 is commercially available.
A height difference is formed between the mounting part 7 and the support plate 13, and the height of the mounting part is lower than that of the support plate 13. A side opening 15 is formed between the inside of the first gasket 14 and the mounting part 7. After the drainage joint and the drainer are assembled, when a basin with an overflow outlet is used, part of the fluid that crosses the water level line can enter the overflow area 5 through the side opening 15 and be discharged into the flow channel 2 of the joint body 1 from the overflow hole 6.
The side wall of the joint body 1 extends to form a water outlet pipe 17 with a flat mouth structure, and the water outlet 4 is arranged at the outer end of the water outlet pipe 17, and the water outlet 4 is runway-shaped. By designing the flat mouth structure, the height of the joint can be reduced and the joint can be miniaturized and thinner.
The flow channel 2 includes a vertical channel 18 and a horizontal channel 19, the inner bottom wall of the horizontal flow channel 2 gradually inclines downward from the inside to the outside, and the inclined inner bottom wall can make the fluid flow out better. In this embodiment, the overflow hole 6 is arranged to communicate with the horizontal channel 19, and the fluid in the overflow area 5 is guided to be discharged into the horizontal channel 19 of the joint body 1 through the surface of the overflow area 5. In some embodiments (not shown in the figure), the overflow hole 6 is designed to be communicated with the vertical channel 18, and the overflow hole 6 can be provided with a certain inclination angle to guide the fluid in the overflow area 5 into the vertical channel 18.
