The impurity filter screen plate is used for secondary filtering of the sewage entering the water inlet, filtering out some large-particle solid impurities, and reducing the influence of the solid impurities on the air tightness of the core body.

[0004] In order to avoid the blockage of the sundries in the sewage to the sewer pipe, the sewage needs to pass through the floor drain screen plate and the impurity filter screen plate twice, the mesh of the impurity filter screen plate is small, although the filtering effect of the sewage can be improved, but the drainage speed of the ground sewage is reduced, and the impurity filter screen plate is easily blocked by the solid sundries, which further reduces the drainage efficiency. In other words, the floor drain cannot consider both the filtering and the drainage efficiency, and needs to be improved. UTILITY MODEL CONTENTS

[0032] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0033] A type of support, such as Figures 1-3 As shown, the device includes a support body 100, a through hole 110 on the support body 100, a filter part 120 on the support body 100 for filtering impurities entering the through hole 110, and a support part 130 for limiting the drain cover 300, thereby maintaining the drainage gap 400 through which water flows between the drain body 200 and the drain cover 300.

[0034] The filter section 120 consists of several frustums 121 circumferentially distributed around the through hole 110. The large-diameter end of the frustum 121 is integrally formed with the end face of the support body 100, and there are gaps between adjacent frustums 121 for water to flow through. Alternatively, the filter section 120 may consist of toothed or triangular protrusions circumferentially distributed around the through hole 110.

[0035] There is a clearance gap 500 between the filter section 120 and the drain cover 300.

[0036] The support 130 includes at least two positioning blocks 131 spaced apart on the support body 100. Each positioning block 131 has a positioning groove 132. The bottom of the positioning groove 132 is for the drain cover 300 to be placed, thereby forming a drainage gap 400 and a clearance gap 500.

[0037] The sidewall shape of each positioning groove 132 is adapted to the edge shape of the drain cover 300. For example, when the cross-sectional shape of the drain cover 300 is square, the sidewall of the positioning groove 132 is right-angled, and the sidewall of the positioning groove 132 limits the circumferential positioning of the drain cover 300; if the cross-section of the drain cover 300 is circular, the sidewall of the positioning groove 132 is arc-shaped.

[0038] In some embodiments, the clearance gap 500 is omitted, and the drain cover 300 is mainly supported by the filter part 120. The positioning groove 132 only limits the drain cover 300 to prevent the drain cover 300 from shifting.

[0039] A floor drain, such as Figures 4-6 As shown in the drawings, the floor drain comprises a floor drain body 200, a floor drain cover 300 and the abovementioned support, the floor drain body 200 is provided with an assembly groove 210 and a drain hole 220 which are in communication, the support body 100 is arranged in the assembly groove 210, the through hole 110 is in communication with the drain hole 220, and the support part 130 limits the floor drain cover 300 and forms a drain gap 400; the upper end of the floor drain cover 300 is flush with the upper end of the floor drain body 200, and the floor drain cover 300 covers the through hole 110.

[0040] In this embodiment, the diameter of the through hole 110 is greater than or equal to the diameter of the drain hole 220.

[0041] The assembly groove 210 is mostly square or circular, the outer peripheral wall of the support body 100 is adapted to the side wall of the assembly groove 210, the lower end of the support body 100 abuts against the groove bottom of the assembly groove 210, and the support body 100 is gap-fitted with the assembly groove 210, so that abnormal displacement of the support body 100 in the assembly groove 210 is avoided.

[0042] The end surface of the floor drain cover 300 is provided with a containing groove 310, the containing groove 310 can be installed with a ceramic tile or other material ground decoration, and the upper and lower end surfaces of the floor drain cover 300 can be upwardly oriented at will.

[0043] Working principle of the floor drain:

[0044] The floor drain body 200 is installed on the ground and connected with a drain pipe, so that the drain hole 220 is in communication with the drain pipe; ground sewage passes through the drain gap 400, the through hole 110 and the drain hole 220 to enter the drain pipe, so that the floor drain realizes normal drainage.

[0045] Since the width of the drain gap 400 is constant, the drain gap 400 can only allow sewage and small-particle sundries to enter, and sundries with large diameters cannot enter the drain gap 400, so that the sewage is first filtered; before the sewage enters the through hole 110 and the drain hole 220, the filtering part 120 performs secondary filtration on sundries in the sewage, especially hair in the sewage; and in the process of drainage, the cooperation of the drain gap 400 and the through hole 110 can allow large-flow water to pass through, so that the drainage efficiency of the floor drain per unit time is ensured, and the floor drain can balance the filtering effect and the drainage efficiency.

[0046] The specific embodiments described in the present application are only illustrative of the spirit of the present application; those skilled in the art to which the present application belongs can make various modifications or supplements to the described specific embodiments or replace them with similar ways, but will not deviate from the spirit of the present application or exceed the scope defined by the appended claims.
