Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of floor drains and relates to a floor drain hair blocking structure. Background Art
[0002] The floor drain is an important interface connecting the drainage pipe system and the ground. It is widely used in places where drainage is required, such as balconies, bathrooms, and swimming pools.
[0003] At present, common floor drains drain water through the filter holes set on the filter and prevent garbage from entering the drainage pipe. However, filamentous or strip-shaped garbage such as hair is not only easy to accumulate on the filter and block the filter holes, but also easy to entangle on the filter, thus causing problems such as poor drainage and difficulty in cleaning.
[0004] To this end, a Chinese patent application (application number: 201620150192.9) discloses an easy-to-clean anti-hair device for a floor drain, comprising an upper filter plate and a lower filter plate, wherein the upper filter plate is provided with a plurality of upper water holes, and the lower filter plate is provided with a plurality of lower water holes; a plurality of positioning posts are provided on the lower filter plate, and positioning holes are provided at positions corresponding to the positioning posts on the upper filter plate, wherein the upper filter plate and the lower filter plate are connected together by matching the positioning posts with the positioning holes, wherein a gap is provided between the upper filter plate and the lower filter plate, and the upper end of the positioning post protrudes from the upper filter plate.
[0005] However, the above method has the following defects: 1. The filtration area and filtration space formed by the upper filter plate and the lower filter plate are small, and need to be cleaned more frequently, which is troublesome. 2. The upper filter plate is flat. If the hair accumulates and is higher than the surface of the upper filter plate, it will hinder the smooth flow of water. 3. The flat-shaped upper and lower filter plates are easy to float when the water flow is too large, affecting the function and the filtration stability is poor. Utility Model Content
[0006] The purpose of the utility model is to solve the above problems in the existing technology and propose a floor drain hair blocking structure. The technical problem to be solved by the utility model is: how to reduce the cleaning frequency and make the filtering smooth and stable.
[0007] The purpose of the utility model can be achieved through the following technical solutions: a floor drain hair blocking structure, including an upper filter plate and a lower filter plate matched with the upper filter plate, the upper filter plate is provided with a plurality of water holes 1, the lower filter plate is provided with a plurality of water holes 2 and a plurality of hair blocking protrusions, the upper filter plate is recessed downward to form a accommodating cavity which is larger at the top and smaller at the bottom, and the hair blocking protrusion protrudes upward from the wall of the accommodating cavity.
[0008] The local leakage and hair blocking structure, the upper filter plate and the lower filter plate are positioned together, the upper filter plate is concave downward, and the inner wall of the upper filter plate is enclosed to form a larger upper and smaller lower accommodation cavity. In actual use, sewage flows to the upper filter plate, the hair is entangled and left on the hair blocking protrusion, and the water flows through the filter hole 1 and the filter hole 2 in turn into the drainage pipe. When the hair accumulates to a certain amount, the upper filter plate and the lower filter plate are separated, and the hair is taken away from the hair blocking protrusion along with the upper filter plate, and the hair on the surface of the upper filter plate can be cleaned. The upper filter plate is concave downward to form a larger upper and smaller lower accommodation cavity, which effectively increases the filtration space and filtration area, improves the filtration capacity, and does not need to be cleaned frequently, making the filtration more sufficient and improving the filtration effect. The upper filter plate is concave downward, and it is not easy to float up when the water flow is too large compared to the flat plate, and the filtration stability is better. Even if there is hair accumulated on the surface of the upper filter plate, the filter hole 1 is partially covered, and the sewage can still gather from the higher places around to the lower place in the center. The sewage can pass through the smaller gap smoothly under the action of its own weight. The hair is intercepted by the hair blocking protrusion, and the hair on the hair blocking protrusion is removed at one time through the upper filter plate, so that the residual hair on the flat surface of the upper filter plate can be conveniently cleaned, and the cleaning is convenient.
[0009] In the above-mentioned floor drain hair blocking structure, the lower filter plate is concave downward, and the lower filter plate is matched with the upper filter plate through the hair blocking protrusion passing through the water hole one. During installation, align the hair blocking protrusion with the water hole one, and move the upper filter plate close to the lower filter plate so that the hair blocking protrusion passes through the water hole one. The hair blocking protrusion of the water hole pair plays a limiting role, thereby making the upper filter plate and the lower filter plate fit together at a suitable angle. Both the upper filter plate and the lower filter plate are concave downward, which is conducive to the upper filter plate and the lower filter plate fitting together more closely.
[0010] The above-mentioned floor drain blocking structure, the upper filter plate includes a plate-shaped flange 1 located at the upper part and a funnel-shaped drainage part 1 located at the lower part, the lower filter plate includes a plate-shaped flange 2 located at the upper part and a funnel-shaped drainage part 2 located at the lower part, the flange 1 and the flange 2 are in abutment with each other, a gap is left between the drainage part 1 and the drainage part 2, and the inner wall of the drainage part 1 is enclosed to form a accommodating cavity. In actual use, the drainage part 2 wraps the drainage part 1 and extends into the drainage pipe, the flange 1 and the flange 2 are in abutment with each other and are placed on a supportable plane around the drainage pipe, completing the coordination and positioning of the local drain blocking structure. The flange 1 and the flange 2 are both plate-shaped and fully contact the support surface, which is conducive to achieving stable support. The drainage part 1 and the drainage part 2 are both funnel-shaped, which is conducive to increasing the filtration area and filtration space, improving the filtration effect while avoiding too frequent cleaning. A gap is left between the drainage part 1 and the drainage part 2. When the water hole 1 and the water hole 2 are arranged alternately, the sewage passing through the water hole 1 can also flow smoothly through the gap to the water hole 2.
[0011] In the above-mentioned floor drain blocking structure, the upper filter plate further includes step portion 1, which smoothly transitions with flange 1 and drainage portion 1, respectively, and the lower filter plate further includes step portion 2, which smoothly transitions with flange 2 and drainage portion 2, respectively, and a gap is left between step portion 1 and step portion 2. Step portion 1 and step portion 2 are in full contact with the support surface, which is conducive to achieving stable support. Step portion 1 and step portion 2 are abutted against and placed on a supportable plane around the drainage pipe, and together with the combination of flange 1 and flange 2, stable support of the local drain is achieved.
[0012] The hair blocking structure of the floor drain includes a hair blocking protrusion and a hair blocking plate, and the hair blocking protrusion and the hair blocking plate are evenly distributed on the flange 2. The arrangement of the hair blocking column and the hair blocking plate can not only block the hair with a large volume, but also ensure the smooth passage of water flow without blocking.
[0013] In the above-mentioned floor drain hair-blocking structure, the upper filter plate is provided with a handle 1 protruding upward, and the lower filter plate is provided with a handle 2 protruding downward. When the accumulated hair reaches a certain amount, a person can easily separate the upper filter plate from the lower filter plate by hooking the handle 1 and lifting it upward. If the upper filter plate and the lower filter plate cannot be separated smoothly by just lifting the handle 1, both of them can be taken out at the same time, and the handle 1 and the handle 2 can be pulled in opposite directions at the same time to separate the upper filter plate from the lower filter plate smoothly.
[0014] Compared with the existing technology, the local leakage blocking structure has the following advantages:
[0015] 1. In the local leakage-blocking structure, the upper filter plate is recessed downward to form a larger upper and smaller lower accommodating cavity, which effectively increases the filtration space and filtration area, improves the filtration capacity, and eliminates the need for frequent cleaning, making the filtration more complete and improving the filtration effect.
[0016] 2. In the local leakage-blocking structure, the upper filter plate is concave downward. Even if hair accumulates on the surface of the upper filter plate, once the filter holes are partially covered, sewage can still gather from the higher places around to the lower place in the center, and the sewage can smoothly pass through the smaller gap under the action of its own weight.
[0017] 3. In the local leakage hair blocking structure, the hair is intercepted by the hair blocking protrusion, and the hair on the hair blocking protrusion is cleared at one time through the upper filter plate, so that the residual hair on the flat surface of the upper filter plate can be conveniently cleaned, which is convenient for cleaning.

DETAILED DESCRIPTION
[0023] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0024] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
[0025] like Figure 1-Figure 4 As shown, the local leakage blocking structure includes an upper filter plate 1 and a lower filter plate 2, and both the upper filter plate 1 and the lower filter plate 2 are concave downward. The upper filter plate 1 includes a step portion 1c, a plate-shaped flange 1a located at the upper part, and a funnel-shaped drainage portion 1b located at the lower part, and the step portion 1c is smoothly transitioned with the flange 1a and the drainage portion 1b respectively. The lower filter plate 2 includes a step portion 2c, a plate-shaped flange 2a located at the upper part, and a funnel-shaped drainage portion 2b located at the lower part, and the step portion 2c is smoothly transitioned with the flange 2a and the drainage portion 2b respectively. The flange 1a is against the flange 2a, and a gap is left between the step portion 1c and the step portion 2c, and a gap is left between the drainage portion 1b and the drainage portion 2b, and the inner wall of the drainage portion 1b is enclosed to form a accommodating cavity 6 that is larger at the top and smaller at the bottom.
[0026] The upper filter plate 1 is provided with a plurality of water holes 3, which are evenly distributed on the flange 1a. The drainage portion 2b of the lower filter plate 2 is provided with a plurality of water holes 4.
[0027] The flange 1a and the flange 2a are both plate-shaped and abut against each other, and the step portion 1c and the step portion 2c abut against each other. In actual use, the drain portion 2b wraps the drain portion 1b and extends into the drainage pipe. The flange 2a and the step portion 2c are placed on a supportable plane around the drainage pipe, fully contacting the support surface, and jointly achieving stable support. The drain portion 1b and the drain portion 2b are both funnel-shaped, which is conducive to increasing the filtration area and filtration space, improving the filtration effect, and avoiding too frequent cleaning. There is a gap between the drain portion 1b and the drain portion 2b. When the water hole 13 and the water hole 24 are staggered, the sewage passing through the water hole 13 can smoothly flow through the gap to the water hole 24.
[0028] The lower filter plate 2 is provided with a plurality of hair-blocking protrusions 5, which protrude from the wall of the accommodating cavity 6. The lower filter plate 2 is matched with the upper filter plate 1 through the hair-blocking protrusions 5 passing through the water hole 3. During installation, the hair-blocking protrusions 5 are aligned with the water hole 3, and the upper filter plate 1 is brought close to the lower filter plate 2, so that the hair-blocking protrusions 5 pass through the water hole 3. The water hole 3 limits the hair-blocking protrusions 5, so that the upper filter plate 1 and the lower filter plate 2 are matched together at a suitable angle.
[0029] The hair blocking protrusion 5 includes a hair blocking column 5a and a hair blocking plate 5b, which are evenly distributed on the flange 2a. The arrangement of the hair blocking column 5a and the hair blocking plate 5b can not only block the hair with a large volume, but also ensure the smooth passage of water without blocking. The sewage enters the drainage part 1b through the flange 1a and the step part 1c.
[0030] The upper filter plate 1 is provided with a handle 7 protruding upward, and the lower filter plate 2 is provided with a handle 2 8 protruding downward. When the accumulated hair reaches a certain amount, the person can easily separate the upper filter plate 1 and the lower filter plate 2 by hooking the handle 1 7 and lifting it upward. If the upper filter plate 1 and the lower filter plate 2 cannot be separated smoothly by just lifting the handle 1 7, take out both of them at the same time, and pull the handle 1 7 and the handle 2 8 in opposite directions at the same time, so that the upper filter plate 1 and the lower filter plate 2 can be separated smoothly.
[0031] In actual use, sewage flows to the upper filter plate 1, and the hair is entangled and retained on the hair-blocking protrusion 5. The water flows through the filter hole 1 and the filter hole 2 in sequence and enters the drainage pipe. When the hair accumulates to a certain amount, the upper filter plate 1 and the lower filter plate 2 are separated by the handle 1 7 and the handle 2 8, and the hair is taken away from the hair-blocking protrusion 5 along with the upper filter plate 1, and the hair on the surface of the upper filter plate 1 can be cleaned.
[0032] The upper filter plate 1 and the lower filter plate 2 are both concave downward, forming a larger upper and smaller lower accommodation chamber 6, which effectively increases the filtration space and filtration area, improves the filtration capacity, and makes the filtration more complete without frequent cleaning, thereby improving the filtration effect. The upper filter plate 1 is concave downward, and is less likely to float up when the water flow is too large than a flat plate, and has better filtration stability. Even if hair accumulates on the surface of the upper filter plate 1, sewage can still converge from the higher places around to the lower place in the center, and sewage can smoothly pass through the smaller gap under the action of its own weight. The hair is intercepted by the hair blocking protrusion 5, and the hair on the hair blocking protrusion 5 is removed at one time by the upper filter plate 1, so that the residual hair on the flat surface of the upper filter plate 1 can be easily cleaned, which is convenient for cleaning.
[0033] Although the present invention uses more terms such as upper filter plate 1, flange 1a, drainage part 1b, step part 1c, lower filter plate 2, flange 2a, drainage part 2b, step part 2c, water hole 13, water hole 24, hair blocking protrusion 5, hair blocking column 5a, hair blocking plate 5b, accommodating chamber 6, handle 17, handle 28, etc., it does not exclude the possibility of using other terms. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
