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 guide column and a plurality of positioning columns shorter than the guide column are provided on the lower filter plate, a positioning hole is provided on the upper filter plate at a position corresponding to the positioning column, and a guide hole is provided on the upper filter plate at a position corresponding to the guide column.

[0005] However, the above method has the following defects: when separating the upper filter plate and the lower filter plate, it is necessary to press the guide column and move the upper filter plate upward, but when the upper filter plate is matched with the lower filter plate, the upper filter plate is placed within the convex edge of the lower filter plate, and it is difficult to find the fulcrum for moving the upper filter plate, making disassembly more troublesome and difficult. Utility Model Content

[0006] The purpose of the utility model is to solve the above problems in the prior art and propose a floor drain blocking structure. The technical problem to be solved by the utility model is: how to achieve convenient and quick disassembly.

[0007] The purpose of the utility model can be achieved through the following technical solutions: a floor drain hair blocking structure, comprising an upper filter plate and a lower filter plate, the upper filter plate is provided with a plurality of water through holes 1, the lower filter plate is provided with a plurality of water through holes 2 and a plurality of upwardly protruding hair blocking parts, characterized in that the upper filter plate is also provided with a downwardly protruding pressing protrusion, the lower filter plate is also provided with a matching hole, when the upper filter plate is stacked on the lower filter plate, the hair blocking part passes through the water through holes 1 and protrudes from the upper surface of the upper filter plate, and the pressing protrusion passes through the matching hole and protrudes from the lower surface of the lower filter plate.

[0008] The local leakage hair blocking structure, when installing, align the pressing convex part with the matching hole, align the hair blocking part with the water hole 1, then make the upper filter plate and the lower filter plate close to each other, the pressing convex part passes through the matching hole 1 and protrudes from the lower surface of the lower filter plate, and the hair blocking part passes through the water hole 1 and protrudes from the upper surface of the upper filter plate, until the upper filter plate is stacked on the lower filter plate. In actual application, the sewage flows to the upper filter plate, the hair is intercepted by the hair blocking part, and the liquid part flows through the water hole 1 and the water hole 2 in turn into the drainage pipe. When disassembling, press the hair blocking part from one side of the upper filter plate, press the pressing convex part from one side of the lower filter plate, and apply force at the same time to separate the upper filter plate and the lower filter plate. When disassembling the upper filter plate and the lower filter plate, press the hair blocking part and the pressing convex part at the same time to complete the disassembly operation, which is convenient and quick. The hair is intercepted by the hair blocking convex, and the hair on the hair blocking convex 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 easily cleaned, which is convenient to clean. Align the pressing protrusion with the matching hole to make the upper filter plate initially aligned with the lower filter plate, and then align the blocking part with the water hole 1 to make the upper filter plate further initially aligned with the lower filter plate, which is conducive to more conveniently and quickly aligning the upper filter plate with the lower filter plate.

[0009] In the above-mentioned floor drain blocking structure, there are two pressing protrusions and they are arranged opposite to each other. The pressing protrusions include a limiting protrusion. When the upper filter plate is stacked on the lower filter plate, the limiting protrusion is engaged with the matching hole. During installation, the pressing protrusion is aligned with the matching hole, so that the upper filter plate and the lower filter plate are close to each other, and the limiting protrusion is abutted against the inner wall of the matching hole, and then a slightly larger thrust is applied to make the upper filter plate and the lower filter plate continue to approach each other, and the pressing protrusion is slightly deformed, and the limiting protrusion protrudes from the lower surface of the lower filter plate, and the limiting protrusion is engaged with the matching hole. At this time, the upper filter plate is stacked on the lower filter plate, and the upper filter plate and the lower filter plate are engaged together. In actual application, the limiting protrusion of the pressing protrusion is engaged with the matching hole to prevent the upper filter plate and the lower filter plate from floating up when the water flow is too large, so that the sewage filtration is carried out stably. When disassembling, press the hair blocking part from one side of the upper filter plate, and press the pressing convex part from one side of the lower filter plate.

When disassembling, hook the handle, lift the upper filter plate and the lower filter plate that are clamped together, and then press the handle and the pressing protrusion at the same time, so that the upper filter plate and the lower filter plate are separated, and the disassembly is more convenient and quick.

[0011] In the above-mentioned floor drain blocking structure, the upper surface of the pressing protrusion is sunken to form a groove, and the groove is connected to the guide hole. When the upper filter plate is stacked on the lower filter plate, a clearance space is formed between the inner wall of the groove and the handle. When disassembling, the personnel can put their fingers into the clearance space, easily hook the handle, and lift the upper filter plate and the lower filter plate that are clamped together, which makes the operation more convenient and quick.
