Description

Technical Field

[0001] The invention relates to the field of drainage, and in particular to a drain that is easy to clean. Background Art

[0002] Drains are usually set on the ground in various places such as kitchens, bathrooms and balconies. The drain is an important interface connecting the drainage pipe system and the indoor basin outlet pipe. Existing basins usually have a corrugated pipe as an outlet pipe at its outlet. The corrugated pipe is inserted into the drain to connect to the drainage pipe system, thereby prompting water to flow into the drainage pipe system for drainage.

[0003] After searching, a Chinese patent application with application publication number CN113482129B discloses an anti-odor drainer, including a main body, in which a channel for fluid to pass through is opened; an elastic anti-odor sleeve, which is installed under the main body; the two sides of the lower part of the elastic anti-odor sleeve are tightly attached to each other to form a lower sealing part, thereby blocking the channel; the lower sealing part can be opened under the pressure of a certain amount of fluid, and reset after the fluid passes. The present invention is provided with an elastic anti-odor sleeve on the main body, and the main body is used to connect the elastic anti-odor sleeve and the drain pipe or bellows of the basin. Compared with the method of directly extending the drain pipe into the drain port, it has a better sealing effect. At the same time, the lower sealing part of the elastic anti-odor sleeve can be opened for drainage when there is a water flow impact; when the water flow is drained, the lower sealing part will reset to a closed state when it is not subject to external force, effectively preventing odor from overflowing, and has a good anti-odor effect.

[0017] On the basis of the above, the first anti-blocking mechanism 5 is composed of a rotating component and a cleaning component, and the rotating component and the cleaning component are matched with each other, and the rotating component is rotatably connected to the bottom of the inner shell 8.

[0018] On the basis of the above, the rotating assembly consists of a rotating rod 11, multiple blades 12, a rotating disk 13 and two push plates 14, and the multiple blades 12 are spirally fixed on the outer wall of the rotating rod 11, and the blades 12 are inclined. A through hole 10 is opened at the bottom of the inner shell 8, and a rotating connection is formed between the through hole 10 and the rotating rod 11 through a bearing.

Since the blades 12 are spirally distributed on the outer wall of the rotating rod 11, and the blades 12 are inclined, when impacted by the sewage, the blades 12 will drive the rotating rod 11 to rotate under the action of the impact force of the sewage. At this time, the turntable 13 will drive the push plate 14 to rotate synchronously with the rotation of the rotating rod 11, and the push plate 14 will rotate when rotating.

At this time, as the rotating rod 11 continues to rotate, the push plate 14 will push the connecting plate 18 to rotate, and the connecting plate 18 will drive the first cleaning plate 16 to rotate synchronously when rotating. Since the second cleaning plate 17 is vertically arranged with the first cleaning plate 16, the second cleaning plate 17 will clean the lower surface of the filter screen 4 while the first cleaning plate 16 cleans the upper surface of the filter screen 4. The second cleaning plate 17 can push out the impurities stuck in the filter holes of the filter screen 4, and the first cleaning plate 16 will sweep the pushed out impurities to one side. The cooperation between the first top block 23 and the second cleaning plate 17 can effectively process the impurities adhered to the filter screen 4, thereby improving the filtering effect of the filter screen 4 on sewage, preventing hair from accumulating inside the drainage pipe and causing the inside of the drainage pipe to be blocked, thereby affecting the discharge of sewage. When the blade 12 drives the rotating rod 11 to rotate under the impact of sewage, the first top block 23 will rotate synchronously with the rotation of the rotating rod 11. Since the top of the first top block 23 and the bottom of the second top block 24 are both provided with a plurality of continuous protrusions, the cooperation between the first top block 23 and the second top block 24 allows the second top block 24 to drive the rotating rod 11 to rotate synchronously.
