Description

Filter screen for floor drain

Technical Field

The utility model relates to a floor drain technical field, in particular to filter screen for floor drain.

Background

At present, a chinese patent with publication number CN206902889U discloses a floor drain, which comprises a floor drain main body, a floor drain cover and a guide pipe, wherein a floor drain hole is arranged on the floor drain main body in a penetrating manner, the floor drain cover covers the floor drain hole, the guide pipe is fixedly connected to the lower end surface of the floor drain main body and is communicated with the floor drain hole, and the size of the floor drain cover is larger than the cross-sectional size of the floor drain hole. And a stepped ring groove for accommodating the floor drain cover is formed in the upper end surface of the floor drain main body along the edge direction of the floor drain hole. The floor drain cover is provided with a filtering hole. In the process of using the floor drain, the floor drain hole arranged on the floor drain cover can filter flowing water, so that impurities mixed with particles larger than the floor drain hole in the water are not easy to enter the inner part of the floor drain hole. However, in the process of water flowing through the floor drain cover, hair mixed in the water can easily enter the interior of the floor drain main body and block the floor drain hole.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims to provide a filter screen for floor drain, it has can carry out the separation to the hair of aquatic, makes its difficult advantage that blocks up.

The above technical purpose of the present invention can be achieved by the following technical solutions: the utility model provides a filter screen for floor drain, includes the body, be provided with a plurality of filtration pores on the body, be provided with the restriction group that is used for colluding the hair on the top surface of body, restriction group is including circumference evenly distributed in projection on the body top surface, and a plurality of the projection all extends along vertical direction that makes progress.

Through above-mentioned technical scheme, at the in-process of rivers through the body, set up the projection at body top and can collude the hair of aquatic for the difficult jam that enters into the body inside and cause the filtration pore of hair.

Preferably, the number of the limiting groups is several, and the limiting groups are uniformly distributed along the radial direction of the body.

Through above-mentioned technical scheme, set up in a plurality of projections at body top can effectively collude the hair of aquatic and hang for the hair of aquatic is difficult for entering into the body inside and will filter the hole jam.

Preferably, the body comprises an annular supporting body and a cover body fixedly connected to the inner ring of the supporting body; the supporting body is arranged inside the stepped ring groove, and the limiting group is arranged on the top surface of the supporting body; the cover body is bent to one side far away from the support body, and the filter holes are uniformly distributed on the cover body

Through above-mentioned technical scheme, when this filter screen filters out the great impurity of granule, impurity can be accomodate in the cover body is inside, because the cover body is sunken downwards, so can accomodate more impurity in the cover body, and the filter hole on the cover body is difficult for impurity jam.

Preferably, a plurality of through holes are uniformly distributed in the circumferential direction of the support body, and the width of the opening of each through hole is gradually increased towards one side far away from the cover body.

Through the technical scheme, the through holes arranged on the support body can reduce the materials required by the production of the filter screen and reduce the production cost of the filter screen; on the other hand, when water flowed through from supporter upper portion, some impurity that the aquatic was mingled with can enter into inside the through-hole under the dead weight effect to this carries out prefilter to water.

Preferably, the number of the through holes is the same as that of the convex columns in each limiting group, and the through holes are located between two adjacent convex columns of the limiting groups.

Through above-mentioned technical scheme, through-hole evenly distributed is on the supporter for the supporter can have stronger structural strength, guarantees with this that this supporter is difficult for taking place to warp even damage in the use.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

A filter screen for a floor drain comprises a body 1, wherein the body 1 comprises a circular support body 11 and a cover body 12 fixedly connected to the inner ring of the support body 11.

The top surface of the body 1 is provided with a plurality of groups of limiting groups 3, and the plurality of limiting groups 3 are uniformly distributed in the radial direction of the supporting body 11. The limiting set 3 comprises a plurality of convex columns 31 extending vertically upwards, and the plurality of convex columns 31 are circumferentially and uniformly distributed by taking the axis of the support body 11 as the center. Adjacent studs 31 in a number of confinement groups 3 are collinear. The top surface of the body 1 is provided with a through hole 4 extending along the axial direction of the support body 11, and the width of the opening of the through hole 4 gradually increases towards one side far away from the axis of the support body 11. The number of the through holes 4 is the same as that of the convex columns 31 in one group of the limiting group 3, the through holes 4 are distributed between two adjacent convex columns 31 in one group of the limiting group 3, and the distance between the through holes 4 and two adjacent convex columns 31 in one group of the limiting group 3 is the same. In the process of using the filter screen, the convex columns 31 arranged on the body 1 can hook hairs mixed in water.

The cover body 12 is hemispherical, and the middle part of the cover body 12 is bent downwards, a plurality of filter holes 2 are uniformly distributed on the cover body 12, and the filter holes 2 are used for filtering large impurities of particles mixed in water.

The above description is only an exemplary embodiment of the present invention, and is not intended to limit the scope of the present invention, which is defined by the appended claims.
