Technical Field

[0001] The utility model relates to the technical field of household equipment, in particular to a sink drain. Background Art

[0002] A sink drain, also known as a kitchen drain manifold, is a plumbing device used in the kitchen. It is usually installed at the drain outlet at the bottom of the sink and is mainly used to separate solid waste and liquid wastewater. The use of a drain manifold can effectively filter solid waste and prevent it from settling in the sewer, thereby reducing the risk of sewer blockage and helping to maintain a good sanitary environment. The design and quality of the drain play a vital role in drainage effects, preventing blockages, and preventing odor backflow.

It cannot effectively prevent odor backflow and is inconvenient to maintain. It is difficult to meet the modern family's demand for efficient, convenient and environmentally friendly drainage systems. For this reason, we proposed a sink drain. Utility Model Content

The filter cover 6 is hemispherical, the inner cavity of the filter cover 6 is hollow, and the upper surface is an open structure. A plurality of first filter holes are provided on the inner wall of the filter cover 6 .

[0032] Furthermore, four arc-shaped clamping plates 8 equidistantly arranged in a ring are fixedly connected to the upper surface of the secondary filter box body 7, the top of the arc-shaped clamping plates 8 is an arc-shaped plate, and the four arc-shaped clamping plates 8 are movably clamped on the upper surface of the water dropper body 1. A plurality of second filter holes are opened on the inner wall of the secondary filter box body 7, and the diameter of the second filter holes is smaller than the diameter of the first filter holes.

[0033] Furthermore, four equidistantly arranged hair adsorption rods 9 are fixedly connected to the inner wall of the bottom side of the secondary filter box body 7 where the second filter hole is not formed. The hair adsorption rods 9 are composed of a mounting plate and three triangular winding plates. The tops of the three mounting plates are arc-shaped and are all in contact with the bottom surface of the filter cover 6. The angles between the three triangular winding plates and the mounting plate are set to be acute angles.

[0034] Furthermore, the anti-odor backflow device 15 includes an anti-odor floating block 11, a connecting rod 12 and a limiting ring 13. A limiting groove 10 is provided at the lower end of the inner wall of the water dropper body 1. The limiting ring 13 is movably engaged in the limiting groove 10. The outer side surface of the limiting ring 13 fits the inner wall of the limiting groove 10. The inner side surface of the limiting ring 13 is fixedly connected with four connecting rods 12 equidistantly arranged in a ring shape. The anti-odor floating block 11 is fixedly connected to one end of the four connecting rods 12 away from the limiting ring 13.

[0037] Working principle: before using the device, install the water dropper body 1 of the device with the water guide channel 2 as the lower end at the place where water needs to fall, and then cover the integrated fixing ring 4 and filter cover 6 after the secondary filter box body 7 is movably connected to the upper surface of the water dropper body 1 through the arc clamping plate 8. After installation, when the kitchen waste water flows into the device, it first flows into the filter cover 6, and is initially filtered through the first filter hole in the filter cover 6, leaving large solid garbage and impurities in the inner cavity of the filter cover 6. The waste water after the first filtration flows downward into the secondary filter box body 7. The hair or strip-shaped garbage contained in the waste water flowing into the secondary filter box body 7 will be entangled on the hair adsorption rod 9 in the secondary filter box body 7, preventing it from flowing further downward, causing the sewer to be blocked; the waste water after two filtrations flows into the inner cavity of the water dropper body 1 When the wastewater is submerged over the surface of the anti-odor floating block 11, the anti-odor floating block 11 begins to float upward under the action of buoyancy, exposing the inlet of the water guide channel 2 at the lower end, and the wastewater can flow into the sewer through the water guide channel 2. During this process, the limit ring 13 is connected to the periphery of the anti-odor floating block 11 through the connecting rod 12 and is clamped in the limit groove 10, which can prevent the water flow from overturning or moving the anti-odor floating block 11. Before the anti-odor floating block 11 floats up, it can block the odor from the sewer in the water guide channel 2, and when the wastewater arrives, it floats up slowly, so that the water first flows into the water guide channel 2 from the water flow groove 14 to seal the surface of the water guide channel 2, which can effectively prevent the odor from moving up when waterproofing.
