[0024] Through the above arrangement, a plurality of mounting openings 5 ​​are provided on the cover plate 4, and the horizontal distances between each mounting opening 5 and the drain outlet 311 are all different. The corresponding mounting opening 5 can be selected to install the floor drain according to actual needs, and there is no need to process the embedded shifter, which can improve the decoration efficiency.

[0025] The shifter body 3 is integrally injection molded; the drain port 311 is circular and has a hole diameter of 50 mm, which is convenient for installing the corresponding floor drain; in the present application, the number of the mounting ports 5 is four, and the shortest horizontal distances between the edges of the four mounting ports 5 and the edges of the drain port 311 are 10 cm, 20 cm, 30 cm, and 40 cm, respectively; during construction, the drain port 311 is directly connected to the upper end of the sewer pipe, and then the ground is poured with concrete. After the pouring is completed, the concrete covers the lower end of the drain pipe portion 31 to fix the shifter body 3 on the ground. During repair, if there is a construction deviation in the sewer pipe, the corresponding installation opening 5 is selected according to the deviation distance to install the floor drain. For example, if the deviation is about 10 cm, the installation opening 5 corresponding to 10 cm is selected. For example, if the deviation is about 20 cm, the installation opening 5 corresponding to 20 cm is selected. The cover plate 4 and the upper end of the water collecting pipe part 32 are detachably connected, and the cover plate 4 can be rotated around the axis of the drainage pipe part 31 to adjust the angle of each installation opening 5. In this way, the position of the floor drain in each room can be basically consistent; after the floor drain is installed, the remaining installation openings 5 ​​are blocked by the plugs 6.

[0026] As an implementation method, the drainage pipe portion 31 and the water collecting pipe portion 32 are both circular tubes and are coaxially arranged.

[0031] The outer diameter of the plug body 61 is consistent with the inner diameter of the bushing 42. After the plug body 61 is embedded in the bushing 42 through the installation opening 5, the plug body 61 can block the installation opening 5. The first annular flange 62 prevents the plug body 61 from falling from the bushing 42 into the shifter body 3.

[0032] As an implementation method, the cover plate 4 also includes a guide pipe 43 fixedly connected to the lower end of the bushing 42 , the lower end of the guide pipe 43 is inclined toward the axial direction of the water collecting pipe part 32 and directly faces the upper end of the drainage pipe part 31 .

[0033] Through the above arrangement, the time that water stays in the water collecting pipe portion 32 can be reduced, thereby accelerating the discharge speed of water.

[0034] Specifically, after the water from the floor drain is output through the guide pipe 43 , the direction of the water flow is toward the upper end of the drainage pipe portion 31 , and the water flow can directly enter the upper end of the drainage pipe portion 31 and be output through the drainage pipe portion 31 .

[0035] As an implementation method, the embedded shifter also includes a plurality of limiting ribs 7 extending vertically, and the plurality of limiting ribs 7 are arranged in sequence along the lower circumference of the water collecting pipe part 32; the cover plate body 41 is embedded in the upper end of the water collecting pipe part 32, and the upper end of the limiting ribs 7 supports the cover plate body 41, and the upper side of the cover plate body 41 is flush with the upper end of the water collecting pipe part 32.

[0036] Through the above arrangement, the limiting ribs 7 are used to support the cover body 41; the installation of the cover body 41 is relatively convenient.

[0037] Specifically, when installing the cover plate 4 , the cover plate 4 can be directly embedded into the upper end of the water collecting pipe part 32 . In order to increase air tightness, glass glue can be applied on the edge of the cover plate 4 .

[0038] In another embodiment, the connection mode between the cover plate 4 and the shifter body 3 is changed; see Figure 3 The embedded shifter also includes a second annular flange 8 fixedly connected to the upper end of the water collecting pipe part 32 and extending outward, and an arc-shaped long hole 9 is provided on the second annular flange 8. The center of the arc-shaped long hole 9 is located on the axis of the water collecting pipe part 32, and the cover body 41 is in contact with the upper side of the second annular flange 8; the embedded shifter also includes a locking mechanism 10, the locking mechanism 10 includes a screw 101 and a nut 102, the screw 101 extends vertically and is fixedly connected to the lower side of the edge of the cover body 41, the screw 101 passes through the arc-shaped long hole 9, the nut 102 is threadedly connected to the screw 101, and is in contact with the lower side of the second annular flange 8.

[0039] Through the above arrangement, the cover plate 4 has better stability and is also more convenient to remove.

[0040] Specifically, when the nut 102 is tightened, the cover body 41 is pressed against the second annular flange 8; when the cover body 41 needs to be rotated, the nut 102 is loosened. When the cover body 41 is rotated, the cover body 41 rotates around the axis of the drain pipe portion 31, and the screw 101 moves along the arc-shaped long hole 9.
