[0026] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The present invention provides the following embodiments

[0028] Example 1

[0029] The embodiment of the present invention provides a filtering device, such as Figure 1-Figure 2 As shown, it includes: a device shell 1, the top of the device shell 1 is covered with a cover 2, the water inlet of the side wall of the device shell 1 is fixedly connected to the water inlet pipe 4, the water outlet of the side wall of the device shell 1 is fixedly connected to the water outlet pipe 5, and the device shell 1 is provided with a lifting mechanism 3, and the filtering mechanism 6 is arranged inside the device shell 1.

[0030] The working principle and beneficial effects of the above technical solution are:

[0031] A filtering device of the present invention relies on a filter screen plate 18 to block impurities in the water entering the device housing 1 from the water inlet pipe 4. When the impurities are subsequently cleaned, the cover 2 can be driven by the electric telescopic rod 7 to move upward relative to the device housing 1, and then the device housing 1 is opened. During the process of the cover 2 being raised, the cover 2 drives the receiving screen plate 9 and the scraping frame 10 to move upward accordingly through the connecting rod 8. The receiving screen plate 9 can receive and lift the impurities, and the scraping frame 10 can scrape off the impurities attached to the inner wall of the device housing 1 and the outer wall of the fixed rail 17 and the filter screen plate 18. The scraped impurities are moved along the scraping frame 10. Move to the top of the receiving mesh plate 9, and separate the receiving mesh plate 9 from the connecting rod 8 by pulling the assembly and rotating the assembly, and then clean the impurities on the receiving mesh plate 9. In the process of opening the cover 2, the inner wall of the device housing 1 and the outside of the filter mesh plate 18 are simply cleaned by the scraper frame 10, which reduces the workload of subsequent operators for cleaning, and most of the impurities in the device housing 1 can be directly supported by the receiving mesh plate 9, without the operator relying on manual cleaning of the impurities in the device housing 1 step by step, reducing the operator's workload and improving the efficiency of cleaning the impurities in the device housing 1.

[0032] Example 2

[0033] On the basis of Example 1, Figure 1-Figure 3 As shown, the lifting mechanism 3 includes: two electric telescopic rods 7, the fixed ends of the two electric telescopic rods 7 are symmetrically fixedly connected to the outer wall of the device housing 1, and the telescopic ends of the two electric telescopic rods 7 are fixedly connected to the side wall of the cover 2, and four connecting rods 8 are fixedly connected to one side of the bottom of the cover 2, and the bottom of the connecting rods 8 is connected to a lifting component.

[0034] Preferably, the lifting assembly includes: a receiving mesh plate 9, the inner wall of the receiving mesh plate 9 is movably inserted into the four connecting rods 8, and the outer wall of the receiving mesh plate 9 is slidably connected to the inner wall of the device housing 1, and the top of the receiving mesh plate 9 is fixedly connected with a scraping frame 10, and the scraping frame 10 is slidably connected to the inner wall of the device housing 1.

[0035] Preferably, it also includes a plurality of pulling components, and the plurality of pulling components are arranged on the surrounding side of the top of the receiving mesh plate 9, and the pulling components include: four fixed shells 11, the four fixed shells 11 are fixedly connected to the top of the receiving mesh plate 9, and the side walls of the four fixed shells 11 are slidably connected with plug rods 12, one end of the plug rods 12 is movably connected to the four connecting rods 8 in a one-to-one manner, and the other end of the plug rods 12 slides through the side wall of the fixed shell 11 and is fixedly connected to a sliding plate 13, and the sliding plate 13 is slidably connected to the fixed shell 11, and a spring 14 is sleeved on the plug rod 12 located in the fixed shell 11, and the two ends of the spring 14 are respectively fixedly connected to the side wall of the sliding plate 13 and the inner wall of the fixed shell 11.

[0036] Preferably, a rotating assembly is also included, and the rotating assembly is connected to the insertion rod 12. The rotating assembly includes: a handle 15, one end of the four insertion rods 12 is rotatably connected to the handle 15, and four slots 16 are opened on the top of the receiving mesh plate 9, and the handles 15 are movably connected in the slots 16 one by one.

[0037] The working principle and beneficial effects of the above technical solution are:

[0038] The above-mentioned lifting component includes a receiving mesh plate 9, the inner wall of the device housing 1 is slidably connected to the receiving mesh plate 9, four connecting rods 8 are movably inserted into the inner wall of the receiving mesh plate 9, and the top of the receiving mesh plate 9 is fixedly connected to a scraping frame 10. The lifting component can be used to lift impurities inside the device housing 1 and located between the filtering mechanism 6 and the water inlet pipe 4. During the lifting, the residual water in the device housing 1 falls into the bottom of the device housing 1 through the receiving mesh plate 9, and the impurities remain on the receiving mesh plate 9.

[0039] Among them, the pulling component includes a fixed shell 11, and four fixed shells 11 are fixedly connected to the top of the receiving mesh plate 9. The inner walls of the four fixed shells 11 are slidably connected with plug rods 12, and the plug rods 12 are movably inserted in the connecting rod 8. The outer wall of the plug rod 12 is fixedly connected with a sliding plate 13, and the sliding plate 13 is slidably connected to the inner wall of the fixed shell 11. The outer sleeve of the plug rod 12 is provided with a spring 14, and the two ends of the spring 14 are respectively fixedly connected to the outer wall of the sliding plate 13 and the inner wall of the fixed shell 11. The pulling component can limit the connection between the connecting rod 8 and the receiving mesh plate 9, so that the connecting rod 8 can pull the receiving mesh plate 9 to rise and fall accordingly.

[0040] Secondly, the rotating assembly includes a handle 15, and the outer walls of the four insertion rods 12 are rotatably connected to the handle 15. Four slots 16 are provided on the top of the receiving mesh plate 9. The handle 15 is movably connected to the slot 16. The handle 15 can be temporarily stuck in the slot 16, so that the insertion rod 12 can temporarily remain away from the connecting rod 8, thereby facilitating the operator to release the connection between the insertion rod 12 and the connecting rod 8 one by one, so that the device can be used by one person to separate the receiving mesh plate 9 from the four connecting rods 8, thereby improving the convenience of device operation.

[0041] The lifting mechanism 3 arranged above blocks the impurities in the water entering the device housing 1 from the water inlet pipe 4 by relying on the filter screen plate 18. When the impurities are cleaned later, the cover 2 can be driven to move upward relative to the device housing 1 by the electric telescopic rod 7, and then the device housing 1 is opened. In the process of the cover 2 being raised, the cover 2 drives the receiving screen plate 9 and the scraping frame 10 to move upward accordingly through the connecting rod 8. The receiving screen plate 9 can receive and lift the impurities, and the scraping frame 10 can scrape off some impurities attached to the inner wall of the device housing 1, the fixed rail 17 and the outer wall of the filter screen plate 18. The scraped impurities move along the scraping frame 10 to the top of the receiving screen plate 9, and the handle 15 is pulled to make the insertion rod 12 leave the corresponding connecting rod 8. The connecting rod 8 allows the sliding plate 13 to slide inside the fixed shell 11, causing the spring 14 to deform accordingly. When the handle 15 is pulled to the top of the corresponding slot 16, the handle 15 is rotated so that the handle 15 is stuck in the slot 16. The handles 15 are operated one by one to separate the receiving mesh plate 9 from the connecting rod 8, and then the impurities on the receiving mesh plate 9 can be cleaned. When the clean receiving mesh plate 9 is to be reinstalled on the four connecting rods 8 later, the four connecting rods 8 are inserted into the receiving mesh plate 9, and then the handles 15 are rotated one by one to make the handle 15 leave the corresponding slot 16, and then the insertion rod 12 can be inserted into the connecting rod 8 under the action of the elastic force of the spring 14, and the receiving mesh plate 9 can be installed on the connecting rod 8.

[0042] Example 3

[0043] On the basis of Example 1 or 2, Figure 1-Figure 3 , Figure 5-Figure 6 As shown, the filtering mechanism 6 includes: two fixed rails 17, the fixed rails 17 are fixedly connected to the inner walls of the front and rear sides of the device housing 1, respectively, the inner walls of the two fixed rails 17 are slidably connected with T-shaped rods 21, a filter screen plate 18 is fixedly connected between the two T-shaped rods 21, the left and right sides of the filter screen plate 18 are fixedly connected with a receiving box 19, the bottom of the receiving screen plate 9 is provided with a box groove 20, and the receiving screen plate 9 close to the connecting rod 8 is movably inserted into the box groove 20.

[0044] Preferably, it also includes two T-shaped columns 22, which are respectively fixedly connected to the top of the fixed rail 17 near the left and right sides, and the outer wall of the T-shaped column 22 is rotatably connected to a limiting block 23, and the inner wall of the limiting block 23 is threadedly connected to a limiting screw 24, and the limiting screw 24 is movably inserted in the T-shaped rod 21.

[0045] The working principle and beneficial effects of the above technical solution are:

[0046] The above-mentioned filtering mechanism 6 includes a fixed rail 17, and the inner wall of the device housing 1 and the front and rear sides are respectively fixedly connected with the fixed rails 17, the inner walls of the two fixed rails 17 are slidably connected with T-shaped rods 21, and a filter screen plate 18 is fixedly connected between the two T-shaped rods 21. The left and right sides of the filter screen plate 18 are fixedly connected with a receiving box 19, and the bottom of the receiving screen plate 9 is provided with a box groove 20. The receiving screen plate 9 on the side close to the connecting rod 8 is movably inserted in the box groove 20. The receiving box 19 can receive some impurities that fall during the disassembly of the filter screen plate 18, thereby reducing the impurities on the filter screen plate 18 from falling directly into the device housing 1, which increases the difficulty of subsequent cleaning inside the device housing 1.

[0047] Secondly, the filtering mechanism 6 also includes a T-shaped column 22, and the top of the fixed rail 17 and the T-shaped columns 22 are fixedly connected respectively near the left and right sides. The outer wall of the T-shaped column 22 is rotatably connected to a limiting block 23, and the inner wall of the limiting block 23 is threadedly connected to a limiting screw 24. The limiting screw 24 is movably inserted into the T-shaped rod 21. The limiting block 23 is rotated onto the T-shaped rod 21, which can limit the T-shaped rod 21 and the filter screen plate 18 to move upward. By inserting the limiting screw 24 into the T-shaped rod 21, the limiting block 23 can be constrained to rotate around the T-shaped column 22.

[0048] The above structural design can make the limiting screw 24 leave the T-bar 21 by rotating the limiting screw 24, and then the corresponding limiting block 23 can be rotated to make the limiting block 23 leave the top of the T-bar 21. After operating the limiting screw 24 and the limiting block 23 one by one, the filter plate 18 and the receiving boxes 19 on both sides can be slid upward and pulled out. In this process, the movement of the filter plate 18 may cause impurities blocked in the holes therein to move and fall out, and the receiving boxes 19 can receive the fallen impurities, thereby reducing the situation where the impurities on the filter plate 18 directly fall into the device housing 1, which increases the subsequent workload of cleaning the impurities in the device housing 1, thereby improving the practicability of the device, and the disassembly and installation of the filter plate 18 is relatively simple, thereby improving the efficiency of the disassembly and installation of the filter plate 18.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
