The wall body base layer and the ground floor slab base layer are coated with waterproof paint, so that water penetrating through the abutted seams of the walls and the floor tiles is prevented from entering the wall body or the floor slab, and the floor leakage of a shower room or the wall surface of an adjacent room is prevented. But the water accumulation between the floor tiles and the ground waterproof coating layer is gradually increased along with the time.
The traditional floor drain can only drain the accumulated water above the floor tile on the floor of the shower room, but can not drain the accumulated water which seeps into the waterproof layer below the floor tile due to the long-time action. Because the ground of other adjacent rooms (or corridors) of the shower room is not waterproof, the water seeped from the floor tiles accumulates day and month to a certain amount, and the seeped water can flow outwards to the lower parts of the floor tiles (or wood floors) of other rooms or corridors through the door openings of the shower room, so that the floors of other rooms or corridors leak.

As shown in fig. 1, 2 and 3, the floor drain of the present embodiment includes a sand filtering basket 1, an inner funnel 2, a floor drain cover plate 3 and a light annular rubber ring 4. Fig. 4 is a cross-sectional view of a sand filtering basket, and as shown in fig. 4, the sand filtering basket 1 is a funnel with a large upper part and a small lower part, and is divided into three parts from top to bottom: the device comprises a first conical section 12, a circular truncated cone section 13 and a second conical section 14, wherein the first conical section 12 and the second conical section 14 are circular truncated cones with large upper parts and small lower parts, and the bottom of the first conical section 12 is connected with the top of the circular truncated cone section 13; the bottom of the circular platform section 13 is connected with the top of the second conical section 14, and an annular platform 15 is formed at the top of the second conical section 14; the first conical section 12 is provided with a water filtering hole 16; both the truncated cone section 13 and the second cone section 14 are imperforate. Fig. 5 is a schematic view illustrating the installation of the inner layer funnel and the floor drain cover plate, and as shown in fig. 5, the inner layer funnel 2 comprises a top cover 21 and a funnel part 22; the top cover 21 is a circular ring fixed on the top of the funnel part 22. The top cover 21 is clamped with the top of the sand filtering hanging basket 1, and a filtering hole 26 is formed in the top cover 21; the bottom of the funnel part 22 is turned outwards to form an annular sand filtering groove 23; the bottom of the annular sand screen 23 is positioned at the top of the circular platform section 13 (shown in figure 1); the bottom and the outward turning part of the annular sand filtering groove 23 are provided with sand filtering holes 25; the light annular rubber ring 4 is horizontally placed on the annular platform 15, the thickness of the light annular rubber ring 4 is smaller than the height of the circular table section 13, the bottom of the circular table section 13 is larger than the top of the circular table section 13, the inner diameter of the top of the circular table section 13 is the same as the outer diameter of the light annular rubber ring 4, and the annular rubber ring 4 can be matched with the bottom surface of the annular sand filtering groove 23 for covering and sealing; the floor drain cover plate 3 covers the circular ring of the top cover 21, and a drain hole 31 is formed in the floor drain cover plate.
The working principle is as follows:
when the floor drain is used, the floor drain is arranged in a multi-water room, as shown in figure 1, accumulated water above floor tiles enters an inner layer funnel 2 through a water drainage hole 31 on a floor drain cover plate 3, then downwards passes through a hole in the middle of a light annular rubber ring 4 and then is discharged from the bottom of a sand filtering hanging basket 1 and enters a sewer pipeline; the accumulated water below the floor bricks flows into the annular sand filtering groove 23 of the inner layer funnel 2 through the water filtering holes 16 on the sand filtering hanging basket 1, and is discharged from the bottom of the sand filtering hanging basket 1 through the holes in the light annular rubber ring 4 after passing through the sand filtering holes 25 and enters a sewer pipeline. In the technical scheme of the invention, the circular truncated cone section 13 and the second conical section 14 are not provided with holes, so that accumulated water above the floor tiles cannot enter the space below the floor tiles. In addition, a light annular rubber ring 4 is placed on the annular platform 15, the thickness of the light annular rubber ring 4 is smaller than the height of the circular platform section 13, the bottom of the circular platform section 13 is larger than the top of the circular platform section 13, the inner diameter of the top of the circular platform section 13 is the same as the outer diameter of the light annular rubber ring 4, and the annular rubber ring 4 can be matched with the bottom surface of the annular sand filtering groove 23 for sealing. Therefore, if the bottom of the sand filtering hanging basket 1 is blocked, the circular truncated cone section 13 is filled with water, and at the moment, the light annular rubber ring 4 floats upwards to the top of the circular truncated cone section 13 under the action of water and is matched with the bottom surface of the annular sand filtering groove 23 for sealing, so that the sand filtering holes 25 are blocked, and accumulated water is prevented from being refilled below floor tiles. At the moment, the floor drain cover plate 3 can be taken out from the top cover 21, and the inside of the floor drain cover plate is cleaned and dredged through the upper opening of the inner-layer funnel 2; if the blockage is serious, the clamping part of the top cover 21 and the sand filtering hanging basket 1 can be loosened after dredging and draining, then the inner-layer funnel 2 is taken out of the sand filtering hanging basket 1, then the light annular rubber ring 4 is taken out, and the blockage in the light annular rubber ring is deeply cleaned. After being cleaned, the floor drain cover plate 3 is sequentially placed into the light annular rubber ring 4 and the inner layer funnel 2 and clamped tightly, and then the floor drain cover plate is covered in the circular ring of the top cover 21, so that the assembly is completed, and the floor drain cover plate can be used continuously. When the floor drain is normally used or blocked, accumulated water in the floor drain cannot flow into the lower part of the floor tile.
A screen may be placed in the annular sand screen 23 to further filter fine sand flowing from below the floor tiles. After a period of use, the inner funnel 2 can be removed from the sand screen basket 1 and cleaned in the annular sand screen 23.
The light annular rubber ring can be a hollow rubber ring, and can also be a rubber ring made of light materials, and the density of the rubber ring is smaller than that of water.
The annular rubber ring 4 can be matched with the bottom surface of the annular sand filtering groove 23 for covering and sealing in various ways, for example, a groove matched with the annular rubber ring 4 is arranged on the lower bottom surface of the annular sand filtering groove 23, so that the annular rubber ring 4 is embedded into the groove after floating upwards to be matched with the annular sand filtering groove 23 for sealing; the bottom surfaces of the annular rubber ring 4 and the annular sand filtering groove 23 can be provided with mutually matched convex and concave grooves, so that the annular rubber ring and the annular sand filtering groove can be matched and sealed.
