[0027] Embodiment 2: Figures 3 to 6As shown, a drainage floor drain joint using the above-mentioned floor drain core includes a three-way joint 100, an intermediate connector 200 and a floor drain core 300 which are sequentially plugged in from top to bottom, the right drainage chamber of the floor drain core 300 is connected to the lower interface of the three-way joint through the intermediate connector, and a ground drain outlet 210 located above the left drainage chamber of the floor drain core 300 is provided on the lower left side of the intermediate connector 200. The utility model is installed on the floor drain, and can be used for draining water from water-using equipment such as laundry sinks, washing machines, and mop sinks, and can also drain ground water. When in use, the middle connector 200 is inserted into the mounting hole in the middle of the floor drain panel, and the upper interface and the side interface of the three-way pipe are used to connect the drain pipes of equipment such as laundry sinks, washing machines, and mop sinks. Water enters the right drainage cavity 320 of the floor drain core through the lower interface and the inner cavity of the middle connector 200, and then is drained to the sewer pipe. The ground water enters the base of the floor drain through the floor drain panel, and then enters the left drainage cavity 310 of the floor drain core through the ground drain port 210 on the left side of the lower part of the middle connector 200, and then is drained to the sewer pipe. The water from the water-using equipment and the ground water have independent channels, so that the two types of water can be drained independently at the same time without interfering with each other, backflow, residue return, or odor return.
[0028] In this embodiment, the middle of the intermediate connector 200 is provided with a connection seat hole 220 that is plugged into the lower interface of the three-way connector, and the bottom right side of the intermediate connector is provided with an insertion port 230 that is connected to the connection seat hole and plugged into the right drainage cavity. The connection seat hole 220 and the insertion port 230 of the intermediate connector 200 play the role of connecting the lower interface of the three-way connector and the right drainage cavity 320 of the floor drain core.
[0029] In this embodiment, a plurality of trash racks 240 are provided at the floor drain outlet on the left side of the lower part of the intermediate connector 200; the floor drain outlet 210 on the left side of the lower part of the intermediate connector 200 serves to connect the inner cavity of the floor drain base and the left drain cavity 310 of the floor drain core, so that the surface water can enter the left drain cavity 310 through the floor drain outlet 210. At the same time, a plurality of trash racks 240 in a comb shape are provided at the floor drain outlet 210 to intercept debris. A limiting protrusion 250 is provided at the outer periphery of the upper end of the intermediate connector 200 to be stuck on the top of the floor drain panel. After the intermediate connector 200 passes through the mounting hole in the middle of the floor drain panel, the limiting protrusion 250 is stuck on the top of the mounting hole to play a limiting role. The limiting protrusion 250 can be arranged symmetrically on the left and right, can be distributed at intervals along the circumference, or can be arranged in a full circle.
[0030] In this embodiment, the outer periphery of the upper and side interfaces of the three-way joint 100 is provided with an annular groove 140 for installing a sealing ring. The upper and side interfaces are used to connect with the drainage pipe of the water-using equipment, and adopt a plug-in method. By replacing the sealing rings of different outer diameters, drainage pipes of different inner diameters can be adapted, which has good versatility, convenient connection, and good sealing. The number of annular grooves can be 1, 2 or 3. In order to further improve the sealing performance, the number of annular grooves can be increased.
[0031] Embodiment 3: It includes a three-way joint 100, an intermediate connector 200 and a floor drain core 300 which are plugged in from top to bottom, and also includes a cap 400 which can cover the upper interface of the three-way joint. The lower part of the cap is provided with a socket part 410 which can be inserted into the upper interface of the three-way joint. The outer periphery of the socket part is provided with an annular groove for installing a sealing ring. The number of the annular grooves can be 1, 2 or 3. In order to further improve the sealing performance, the number of the annular grooves can be increased. The difference between this embodiment and embodiment 2 is that the upper interface of the three-way joint is equipped with a cap, which can be used to seal the upper interface when it is not in use.
[0032] Embodiment 4: It includes a tee joint 100, an intermediate connector 200 and a floor drain core 300 which are plugged in from top to bottom, and also includes a reducer 500 which can be connected to the side interface of the tee joint. One end of the reducer 500 is provided with a sleeve portion 510 which can be inserted into the outside of the side interface of the tee joint. The other end of the reducer is provided with a water inlet interface 520. The outer diameter of the water inlet interface 520 is smaller than the outer diameter of the side interface of the tee pipe. The outer diameter of the side interface of the tee pipe is 29 mm, and the outer diameter of the water inlet interface 520 is 20 mm. The outer periphery of the water inlet interface is provided with an annular groove for installing a sealing ring. The number of annular grooves can be 1, 2 or 3. In order to further improve the sealing performance, the number of annular grooves can be increased. The difference between this embodiment and embodiment 2 is that the side interface of the tee joint is equipped with a reducer 500. Although different outer diameter seals can be used to adapt to different inner diameters of drain pipes, when the inner diameter of the drain pipe is smaller than the outer diameter of the tee-side interface, the drain pipe cannot be plugged in; therefore, by providing a reducer 500, a drain pipe with a smaller diameter can be connected, further expanding the scope of application. In specific use, the outer diameter of the tee-side interface can be set to be smaller than the outer diameter of the water inlet interface, that is, the outer diameter of the tee-side interface is 20 mm, and the outer diameter of the water inlet interface 520 is 29 mm.
