The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0011] See also Figure 1 - Figure 8 The present invention provides a novel kitchen sink water filter, comprising a main frame 11, a filter chamber 12 is provided inside the main frame 11, and the filter chamber 12 is circular; A high-efficiency filtering structure is fixedly installed on the inner wall of the filter chamber 12; A disc-shaped filter screen 13 is fixedly mounted on the inner wall of the filter chamber 12 . The disc-shaped filter screen 13 is fixed to the filter chamber 12 by a magnetic connection, so it can be disassembled.

[0012] A flat-top conical filter 14 is fixedly installed inside the disc filter 13. The flat-top conical filter 14 is partially located inside the disc filter 13. The center of the flat-top conical filter 14 is parallel to the center of the disc filter 13. The disc filter 13 and the flat-top conical filter 14 are both made of POM material. The material has excellent properties such as heat resistance, wear resistance, and corrosion resistance, and has a small friction coefficient and good self-lubricating property. It can still play a very good filtering role in the face of high-temperature liquids and corrosive liquids, and is suitable for various sinks on the market. When water flows through the disc filter 13 and the flat-top cone filter 14, impurities in the water will be separated by the conical structure of the flat-top cone filter 14 to avoid impurity aggregation, and larger impurities, particles, waste, etc. will be blocked outside the net, and the filtered liquid will enter the sewer pipe for discharge. Since the disc filter 13 and the flat-top cone filter 14 can intercept various residues, such as vegetable residues, grease, fruit peels, etc. from entering the sewer, blockage is avoided. At the same time, the workload and cost of cleaning the sewer can be significantly reduced, and the health and life of the sewer system are also protected.

[0013] The main frame 11 is made of stainless steel as a whole. A ring cover 15 is provided on the circumferential surface of the main frame 11. A plurality of first sealing rubber rings 16 and second sealing rubber rings 17 are fixedly installed on the circumferential surface of the main frame 11. The first sealing rubber ring 16 is used to seal between the main frame 11 and the water tank to prevent liquid from leaking into the gap between the first sealing rubber ring 16 and the water tank and causing pollution to the outside world. In order to make the stainless steel body and the water tank tightly combined, two first sealing rubber rings 16 are added for sealing. The rubber ring adopts a bonding design, which is relatively simple to replace after wear in the future.

[0014] The two first sealing rubber rings 16 are both located below the second sealing rubber ring 17. The second sealing rubber ring 17 is funnel-shaped. The second sealing rubber ring 17 is located below the ring cover surface 15. A threaded groove 18 is provided inside the ring cover surface 15. A threaded column 19 is threadedly installed inside the threaded groove 18. A ring member 21 is fixedly installed on the upper end of the threaded column 19. The inner side of the ring member 21 is hollow. A plurality of arc grooves 22 are provided on the side wall of the ring member 21. A circular groove 23 is provided inside each arc groove 22. A damping bearing 24 is provided inside each circular groove 23. The outer ring of each damping bearing 24 is fixedly installed with the inner wall of the circular groove 23. A rotating column 25 is fixedly installed on the inner ring of each damping bearing 24. Each rotating column 25 The arc-shaped clamping member 26 is partially exposed inside the arc-shaped groove 22, and an arc-shaped clamping member 26 is fixedly installed on the circumferential surface of each rotating column 25. Each arc-shaped clamping member 26 is located inside the arc-shaped groove 22. When the size of the mounting groove on the inner wall of the sink is larger than the ring cover surface 15, the staff can rotate the first handle 27 on the arc-shaped clamping member 26 according to the size of the mounting groove for installing the kitchen sink, so that the first handle 27 generates a radial force to the arc-shaped clamping member 26, so that the arc-shaped clamping member 26 drives the rotating column 25 to rotate at the inner ring of the damping bearing 24, so that the first handle 27 can be unfolded on the outside of the annular member 21, and then stuck on the inner wall of the mounting groove on the inner wall of the sink, so that the filter can be stably installed on the sink.

[0015] A first handle 27 is fixedly installed on the upper end of each arc-shaped clamping member 26, and an annular groove 28 is provided on the inner wall of the annular member 21. A swivel 29 is rotatably installed inside the annular groove 28, and a scraper 31 is fixedly installed on the circumferential surface inside the swivel 29. The lower end of the scraper 31 is in contact with the upper end of the disc filter 13, and a second handle 32 is fixedly installed on the upper end of the scraper 31. When the staff needs to clean the garbage on the disc filter 13, the staff can rotate the second handle 32 at this time, so that the second handle 32 generates a radial force to drive the scraper 31 and the swivel 29 to move as a whole inside the annular groove 28, so that the garbage on the disc filter 13 can be scraped and gathered, which is convenient for the staff to carry out centralized cleaning.

[0016] Working principle: The first step is to ensure that the power supply near the sink has been shut down before installation to prevent electric shock accidents during installation. Then, the items around the sink can be cleaned to ensure that there is enough space for installation. Then the staff needs to check whether the sink is complete to ensure that there are no cracks or damage. Then the staff picks up the ring 21 and uses the threaded column 19 under the ring 21 to rotate it in the threaded groove 18 inside the ring cover 15, so that the ring 21 and the main frame 11 are located on the inner wall of the sink. At this time, the first sealing rubber ring 16 and the second sealing rubber ring 17 on the main frame 11 will actively rub against the inner wall of the sink, and then fit closely with the inner wall of the sink to prevent the water flow from carrying debris into the gap between the main frame 11 and the inner wall of the sink and entering the sewer. At the same time, the threaded column 19 and the threaded groove 18 are threaded, so that the ring 21 is fixed as a whole on the ring cover 15 Then, the staff can rotate the first handle 27 on the arc-shaped clamping member 26 according to the size of the installation groove for installing the kitchen sink, so that the first handle 27 generates a radial force to the arc-shaped clamping member 26, so that the arc-shaped clamping member 26 drives the rotating column 25 to rotate at the inner ring of the damping bearing 24, so that the first handle 27 can be unfolded on the outside of the annular member 21, and then the staff can repeat the above steps to unfold the remaining first handles 27, so that the arc-shaped clamping member 26 can fit with the inner wall of the installation groove of the kitchen sink, thereby completing the installation, and then the staff can manually test whether there is any water leakage at the connection between the first sealing rubber ring 16 and the second sealing rubber ring 17 and the sink, and if there is any water leakage, it should be adjusted in time; The second step is to regularly check whether the connection between the disc filter 13 and the flat-top cone filter 14 and the first sealing rubber ring 16 and the second sealing rubber ring 17 is intact after the installation is completed to ensure their normal operation. If water leakage is found in the connection between the first sealing rubber ring 16 and the second sealing rubber ring 17 and the sink, the water source should be turned off in time, and the first sealing rubber ring 16 and the second sealing rubber ring 17 should be checked to see if they are intact. If they are damaged, they should be replaced in time. At the same time, the disc filter 13 and the flat-top cone filter 14 need to be cleaned at least once a week to maintain their filtering effect, and the connection between the first sealing rubber ring 16 and the second sealing rubber ring 17 and the sink, as well as the disc filter 13 and the flat-top cone filter 14 need to be checked once a month to ensure their normal operation. If they are damaged, they need to be replaced in time to prevent the disc filter 13 and the flat-top cone filter 14 from being damaged and causing a decrease in filtering effect; In the third step, when the staff needs to clean the garbage on the disc filter 13, the staff can turn the second handle 32, so that the second handle 32 generates a radial force to drive the scraper 31 and the rotating ring 29 to rotate as a whole inside the annular groove 28, so as to scrape and gather the garbage on the disc filter 13, which is convenient for the staff to clean it in a centralized manner; In the fourth step, when the water flows through the disc filter 13 and the flat-top cone filter 14, the impurities in the water will be separated by the conical structure of the flat-top cone filter 14 to prevent impurities from gathering, and larger impurities, particles, waste, etc. will be blocked outside the net, and the filtered liquid will enter the sewer pipe for discharge.
