The surface cover 400 is disposed in the receiving groove 101 and covers the filter screen 300. The face cover 400 includes a top surface 401 and a side surface 402. The side surfaces 402 are at an obtuse angle with the top surface 401, that is, the side surfaces 402 are inclined outward with respect to the top surface 401, so that when the face cover 400 is disposed in the receiving groove 101, a gap 501 can be formed between the wall surface 103 of the receiving groove 101 and the side surfaces 402 of the face cover 400. The side 402 is inclined outward to accelerate the water flow and thus to discharge water more smoothly. The side 402 has at least one first indentation or hole 403 therein for the passage of water. Specifically, the surface cover 400 is disposed in the receiving groove 101 with the side surface 402 facing downward, and the top surface 401 of the surface cover 400 may be flush with the upper edge 105 of the floor drain body 100 or slightly lower than the upper edge 105 of the floor drain body 100, so as to ensure that the floor drain 10 does not obstruct users while enhancing the aesthetic property of the floor drain 10. And, the highest point of the first notch or hole 403 is higher than the upper surface of the screen 300 to ensure that the water passing through the first notch or hole 403 can reach the upper surface of the screen 300 for filtering.

The embodiment of the utility model provides an in the floor drain 10 that provides, face lid 400 sets up in the holding tank 101 of floor drain body 100 and covers filter screen 300, and face lid 400 includes top surface 401 and the side 402 that is obtuse slope with top surface 401 for face lid 400 can form the gap 501 that can supply rivers to pass through between the side 402 of the wall 103 of holding tank 101 and face lid 400 when setting up in the holding tank 101 of floor drain body 100. In addition, the side surface 402 of the surface cover 400 has at least one first notch or hole 403, and the height of the highest point of the first notch or hole 403 is higher than the upper surface of the filter screen 300, so that the water flow can reach the upper surface of the filter screen 300 through the formed gap 501 and the at least one first notch or hole 403, and then is discharged after being filtered by the filter screen 300, thereby ensuring smooth water discharge. In addition, since the top surface 401 of the face cover 400 does not need to be perforated, the filter screen 300 and the dirt filtered thereon can be hidden under the top surface 401 of the face cover 400, so that the filter screen 300 and the dirt are not exposed, and the use experience of a user is enhanced. The utility model discloses floor drain 10's simple structure has reduced the processing degree of difficulty and manufacturing cost to a certain extent.

To simplify the mounting and dismounting of the face cover 400, in some embodiments, the shape of the face cover 400 may be adapted to the shape of the receiving groove 101. Specifically, the outline shape surrounded by the side surfaces 402 of the face cover 400 is adapted to the shape of the receiving groove 101. For example, as shown in fig. 1 and 2, the receiving groove 101 is square, and the outline surrounded by the side surface 402 of the surface cover 400 is also square. As shown in fig. 3 and 4, the receiving groove 101 is circular, and the contour surrounded by the side surface 402 of the surface cover 400 is also circular. Preferably, the size of the contour shape surrounded by the side surface 402 of the face cover 400 is equal to or slightly smaller than the size of the shape of the receiving groove 101. By adopting the design, the installation of the surface cover 400 can be completed only by placing the surface cover 400 in the accommodating groove 101 without other fixing elements, and the structure is simplified. When the cover is disassembled, the cover 400 is only required to be directly taken out, and the operation is very simple.

The number of the first notches or holes 403 on the side 402 of the cover 400 may be plural to increase the drainage speed. The number of the first gaps or holes 403 may be set according to the actual application requirements, and the present invention is not limited specifically. Preferably, the first notches or holes 403 are uniformly distributed on the side surface 402 to facilitate the uniform passage of water to the filter screen 300 for filtering, thereby increasing the drainage speed and ensuring good filtering effect.

The shape of the first notch or hole 403 may be designed according to the requirements of the actual application. For example, the first indentation or aperture 403 may be square, semi-circular, triangular, etc. Preferably, the shape of the first notch or hole 403 may be trapezoidal, and such shape design can take into account the stability of the surface cover structure and the water passing area of the water flow, so as to ensure that the surface cover 400 can be stably disposed in the accommodating groove 101 while increasing the drainage speed.

To better secure the filter screen 300, the side 402 of the face cover 400 may be inclined at an angle such that the side 402 contacts the edge of the filter screen 300, as shown in fig. 1 and 3, so that the filter screen 300 is pressed downward into the receiving groove 101 by the side 402 of the face cover 400. In this way, the filter screen 300 can be fixed without special fixing elements, simplifying the structure of the floor drain 10.

The filter screen 300 is located right above the through hole 102 of the receiving groove 101 and covered by the cover 400. The water flows through the gap 501 and the first notch or hole 403 between the wall surface 103 of the housing groove 101 and the side surface 402 of the cover 400 to the filter net 300, and is filtered through the filter net 300. In one embodiment of the present invention, the filter screen 300 may have a plurality of elongated first filtering holes 303, and each first filtering hole 303 extends from the central region 305 of the filter screen 300 to the edge of the filter screen 300. Adopt radial rectangular shape filtration pore, can increase the water passing area when guaranteeing the filter effect for drainage speed. In addition, due to the guiding effect of the radial elongated filtering holes, the water flow is gathered from the periphery to the center of the filter screen 300, so that the trapped dirt can be concentrated in the central area 305 of the filter screen 300 as much as possible, and the blocking probability is reduced.

Further, the filter screen 300 may also have a plurality of circular second filter holes 304, the second filter holes 304 being disposed closer to the edge of the filter screen 300 with respect to the first filter holes 303. By providing the second filtering holes 304, the drainage speed is further increased.

In one embodiment, the central region 305 of the screen 300 may also be recessed downward, thereby making dirt trapped by the screen 300 more likely to collect in the central region 305 of the screen 300, further reducing the likelihood of clogging. In this case, the screen 300 includes the downwardly concave central region 305, the peripheral flat surface 307, and the inclined surface 306 connecting the peripheral flat surface 307 and the central region 305. The first filtering openings 303 are formed at least on the inclined surface 306 so that the nature of the downward flow of the water is utilized, in combination with the guiding action of the radially elongated filtering openings, to concentrate the trapped dirt in the central area 305 of the screen 300.

In one embodiment, the edge of the filter screen 300 may be provided with a sidewall 301, and the bottom end of the sidewall 301 is attached to the bottom surface 104 of the receiving groove 101. Since the sidewall 301 has a certain height, the sidewall 301 is designed such that the edge of the filter mesh 300 does not closely contact the bottom surface 104 of the receiving groove 101, thereby allowing the side surface 402 of the cover 400 to more closely contact the edge of the filter mesh 300 to more stably fix the filter mesh 300.

Further, the bottom end of the sidewall 301 of the screen 300 may also have at least one second gap 302, so that the water flow may also flow to the floor drain core 200 below the screen 300 through the second gap 302. In this way, it can be avoided that a part of the water flow cannot be discharged through the first filtering holes 303 and/or the second filtering holes 304 of the filter screen 300 due to the fact that the filter screen 300 is higher than the bottom surface 104 of the accommodating groove 101, and thus, the accumulated water is formed in the accommodating groove 101. The second indentation 302 is preferably flat and rectangular in shape to allow drainage while also retaining dirt to some extent.

In one embodiment, the central region 305 of the screen 300 may also be provided with a pull-up 308. The pulling member 308 may be, for example, a pulling post, a handle, etc., but the present invention is not limited thereto. By means of the pulling member 308, the filter screen 300 can be easily taken out, facilitating the cleaning operation of the filter screen 300.

The floor drain core 200 passes through the through hole 102 of the containing groove 101 of the floor drain body 100 and is arranged right below the filter screen 300. The bottom surface 104 of the receiving groove 101 may be a stepped surface including a first mesa 104a, a second mesa 104b located below the first mesa 104a, and a vertical surface between the first mesa 104a and the second mesa 104 b. The edge of the screen 300 (specifically, the sidewall 301 at the edge of the screen 300) conforms to the first mesa 104 a. Correspondingly, the top of the floor drain core 200 also adopts a stepped structure, so that the floor drain core 200 is fixed to the floor drain body 100 through the cooperation of the stepped structure and the second table surface 104 b. Specifically, the stepped structure at the top of the floor drain core 200 has a limiting surface 201, and the limiting surface 201 is attached to the second table surface 104b, so that the floor drain core 200 is fixed to the floor drain body 100.

The floor drain core 200 may also be provided with a movable handle 202. The two ends of the movable handle 202 are respectively and movably inserted into the mounting holes of the mounting blocks arranged at the two sides of the floor drain core 200, so that the movable handle 202 can rotate and move around the connecting line between the two mounting holes. Generally, in the use position, the movable handle 202 can be in a horizontal position as shown in fig. 1 and 3 to avoid obstructing the discharge of water. When the floor drain core 200 needs to be cleaned or replaced, the movable handle 202 can be rotated to the vertical position, so that the floor drain core 200 can be taken out through the movable handle 202.
