Therefore, most of the floor drain is applied in actual life, the water drainage efficiency is low frequently, and the phenomenon of water accumulation and smooth water drainage in a toilet is easy to occur. Therefore, in view of the shortcomings of the existing floor drain filter screen, the structure of the floor drain filter screen is very necessary to be optimized and redefined.

Disclosure of Invention

The utility model aims to solve the problems and the defects, and provides the floor drain filter screen, which forms the coanda effect of rapid drainage through a special drainage open structure, an arc slope structure and a filter screen part structure, completely eliminates the problem of water accumulation, ensures that a floor drain product can achieve the purpose of rapid and smooth drainage, adopts an integrated structural design, and has simple processing and high production efficiency.

The technical scheme of the utility model is realized as follows: the floor drain filter screen comprises a filter screen body, and is characterized in that the filter screen body is provided with an integrally formed drain opening, an integrally formed arc slope structure is further arranged on the peripheral side wall of the drain opening, and an integrally formed filter screen part is arranged at the bottom of the drain opening.

Further, the filter screen part is also provided with a handle part.

Still further, still be equipped with a plurality of acceleration drainage auxiliary holes on the circular arc slope structure along its circular arc slope structure equidistant arrangement.

Still further, the circular arc slope structure is also provided with a decorative ring with different colors with the filter screen body.

The utility model has the beneficial effects that: the utility model forms the coanda effect of rapid drainage through the special drainage open structure, the circular arc slope structure and the filter screen part structure, completely eliminates the problem of water accumulation, ensures that the floor drain product can achieve the purpose of rapid and smooth drainage, adopts an integrated structural design, and has simple processing and high production efficiency. The utility model effectively solves the defects that most of the existing floor drain is applied in actual life, the drainage efficiency is low frequently, water accumulation easily occurs in a toilet, drainage is smooth, and the like.

Detailed Description

As shown in fig. 1 and fig. 2, the floor drain filter screen according to the present utility model includes a filter screen body 1, in order to achieve the purpose of the present utility model, the filter screen body 1 is provided with an integrally formed drain opening 2, an integrally formed circular arc slope structure 21 is further provided on the peripheral side wall of the drain opening 2, and an integrally formed filter screen portion 22 is provided at the bottom of the drain opening 2. Through special drainage open structure, circular arc slope structure and filter screen portion structure, form the coanda effect, realize smooth, quick drainage, stop bathroom ponding, and integrated structural design can adopt the mould to open and produce, makes its processing very simple, production efficiency is high.

In order to facilitate the user to take out the filter screen from the floor drain for cleaning sundries and cleaning, as shown in fig. 1 and 2, a handle portion 23 is further provided on the filter screen portion 22. The shape of the handle portion 23 may be made in various shapes such as a vertical rod shape, a sphere shape, a square block shape, an oval shape, etc. However, the applicant believes that in order to avoid the influence of the provision of the screen portion 22 on the drainage, the handle portion 23 does not block the mesh holes of the screen portion 22, and the present embodiment is designed in such a manner that the handle portion 23 is a circular arc-shaped handle portion and has a flat structure, which is the most preferable.

In order to further enhance the rapid drainage efficiency of the present utility model, as shown in fig. 1 and 2, the circular arc slope structure 21 is further provided with a plurality of auxiliary drainage acceleration holes 24 which are equally spaced along the circular arc slope structure 21. Through the design of the auxiliary water drainage acceleration holes 24 on the circular arc slope structure 21, part of water is drained away in the process of flowing through the circular arc slope structure 21, so that the water flow can not be excessively concentrated to the filter screen part 22, and the filter screen part 22 can not generate accumulated water even if filtered sundries are blocked. The auxiliary drain acceleration holes 24 may be formed as rectangular holes, or elliptical holes, or circular holes, etc.

In order to further enhance the aesthetic decoration of the product and provide a logo recognition function different from that of the contest products in the same line, as shown in fig. 1 and 2, the circular arc slope structure 21 is further provided with a decorative ring 25 with a color different from that of the filter screen body 1. The decorative ring 25 can be integrally formed by a double-shot molding process, and has the advantages of simple process, durability and no falling.

In order to still further optimize the rapid drainage performance of the screen portion 22, the screen portion 22 is a honeycomb screen portion as shown in fig. 1. Through adopting honeycomb design's filter screen portion, make the interval connecting portion between filtration pore and the filtration pore occupy minimum to whole filter screen area to offer more filtration pore on a limited filter screen area, accelerate the efficiency of drainage.

As shown in fig. 2, the outer periphery of the filter screen body 1 is further provided with an integrally formed outer sleeve connection part 11, and the outer sleeve connection part 11 is used for being sleeved with an upper cavity opening of the floor drain, so that the filter screen body 1 is firmly sleeved in the upper cavity opening of the floor drain. In addition, the outer periphery of the filter screen body 1 above the outer sleeve joint part 11 is also provided with an integrally formed outward flange part 14, the outer side surface of the outward flange part 14 is also provided with a conical inclined surface, and the filter screen body 1 and an upper cavity opening of the floor drain can be contacted together in an anastomotic manner through the design of the conical inclined surface, so that the assembly compactness and stability between the filter screen body and the floor drain are further ensured.

As shown in fig. 2, the bottom of the filter screen body 1 is further provided with an integrally formed inner sleeve connection part 12, and the inner sleeve connection part 12 can be nested with the part of the floor drain with the downward upper cavity mouth so as to meet the nested connection with floor drains with different specifications. As further shown in fig. 2, an inner concave ring groove 13 is also formed between the outer and

inner coupling parts

11 and 12. The concave ring groove 13 can reduce the weight of the filter screen body 1 and the consumption of raw materials on one hand, and can be conveniently nested and assembled with the upper cavity opening of the floor drain with special specification on the other hand.
