The vertical height between the first stepped surface and the second mounting surface is 1mm-20mm.

[0010] Preferably, the upper part of the conical channel is provided with a second step surface, and the drain cover is installed on the second step surface, the outer diameter of the second step surface being 50mm-80mm.

[0011] Preferably, the drain cover has a filter screen structure.

[0012] Preferably, the drain core is equipped with a one-way valve.

[0013] Preferably, the first base and the second base are bonded together, or the first base and the second base are magnetically attached together.

[0014] Preferably, the inner diameter of the drain core is 20mm-40mm.

[0015] The beneficial effects of this invention are: This invention provides a replaceable floor drain. A first base is fixedly installed at the drain hole, and the first base has a drain hole. A second base with a mounting part is included; the second base is mounted on the first base and detachably connected to it, and the mounting part corresponds to the position of the drain hole. A drain core is installed at the mounting part and extends into the drain hole. A drain cover is installed on the mounting part. This solution, by adding a detachable second base, allows for easy replacement of the second base when the drain core and drain cover are incompatible. The structure is simple and the operation is convenient. Attached Figure Description

[0017] To make the technical problems, solutions, and beneficial effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the invention.

[0018] like Figures 1 to 4 As shown, a floor drain that is easy to replace has a first base 10 fixedly installed at the drain hole. The first base 10 has a drain hole 11 and includes: The second base 20 has a mounting part 22. The second base 20 is mounted on the first base 10 and is detachably connected to the first base 10. The mounting part 22 corresponds to the position of the drain hole 11. The drain core 30 is installed at the mounting part 22 and extends into the drain hole 11; The drain cover 40 is installed on the mounting part 22.

[0019] In this embodiment, the first base 10 is provided with a first mounting surface 12, and the second base 20 is provided with a second mounting surface 21 that fits against the first mounting surface 12.

[0020] In this embodiment, both the first mounting surface 12 and the second mounting surface 21 are planar. The thickness B of the second mounting surface 21 is 0.2mm-3mm, specifically, the thickness B of the second mounting surface 21 is 0.75mm.
