Technical Field

[0001] The utility model relates to the technical field of sintered filter screens, and particularly relates to a stainless steel filter screen with single-layer net sintering. Background Art

[0002] A stainless steel filter screen with single-layer net sintering is a filtering material formed by sintering a single-layer stainless steel wire mesh through a specific process. This filter screen has characteristics such as high strength, high corrosion resistance, and high temperature resistance, and is widely used in various filtering devices. Its working principle is to utilize the size of the mesh holes to intercept particulate matter larger than the mesh holes on the surface of the filter screen, thereby achieving the purpose of filtration.

[0003] However, in the prior art, when the traditional single-layer sintered stainless steel filter screen is used in daily household use, impurity particles may be blocked in the filter screen, resulting in a deterioration of the filtering effect. Furthermore, it is necessary to disassemble it, but the disassembly process of the filter screen is rather cumbersome, which may take more time and energy of the user. In addition, frequent disassembly may cause damage to the filter screen, thereby affecting its subsequent use. Therefore, we provide a stainless steel filter screen with single-layer net sintering.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] The present invention provides a technical solution: As Figures 1 - 4 shown, in this embodiment, a single-layer mesh sintered stainless steel filter screen includes: a quick-release mechanism 1. The quick-release mechanism 1 includes a filter box 11. Both sides of the top of the connecting ring 31 are fixedly connected with a handle 32. The inner wall of the connecting ring 31 is fixedly connected with the top end of the sintered filter screen 33. The top of the filter box 11 is nested with a top cover 34. Installation grooves 12 are opened on both sides of the top of the filter box 11. Pressing blocks 13 are arranged on the inner walls of the clamping grooves opened on both sides of the filter box 11. Clamping blocks 14 are arranged in both installation grooves 12. Snap rings 15 are arranged on the tops of both clamping blocks 14. Snap rings 15 are fixedly connected to both sides of the bottom of the connecting ring 31. The inner surface of the snap ring 15 is clamped with the protruding part on the top of the clamping block 14. S-shaped elastic pieces 17 are arranged on one side of both clamping blocks 14 away from the pressing block 13. One side of the pressing block 13 passes through the clamping groove opened on the filter box 11 and is fixedly connected with one side of the clamping block 14. The other side of the clamping block 14 is fixedly connected with one end of the S-shaped elastic piece 17. Slide bars 16 are arranged on the inner walls of the clamping grooves opened on both clamping blocks 14. The other end of the S-shaped elastic piece 17 is fixedly connected with the side of the installation groove 12 away from the inner wall away from the pressing block 13. Both ends of the slide bar 16 are fixedly connected to both sides of the inner wall of the installation groove 12. The outer surface of the slide bar 16 is slidably connected with the inner wall of the clamping groove opened on the clamping block 14. A buffer mechanism 2 is arranged on the top of the filter box 11.

[0024] In this embodiment, when the user needs to disassemble the sintered filter screen 33 to clean the impurities in the filter screen, first open the top cover 34. The user presses the pressing block 13. When the pressing block 13 is pressed, a thrust will be generated. This thrust will be transmitted to the clamping block 14. Then, the clamping block 14 will be subjected to the thrust and squeeze the S-shaped elastic piece 17. As a result, the S-shaped elastic piece 17 will contract and deform. At the same time, when the clamping block 14 moves, it will slide on the sliding rod 16. The sliding rod 16 can ensure the horizontal movement track of the clamping block 14 and avoid the phenomenon of deviation when the clamping block 14 moves. Therefore, the clamping block 14 will contact and limit the clamping ring 15. The staff can take out the connecting ring 31 and the sintered filter screen from the filter box 11 with their hand 32 to clean the impurities in the sintered filter screen 33. Therefore, the sintered filter screen 33 can play its filtering function more effectively and extend its service life.

[0025] As Figure 2 and Figure 4 shown, the buffer mechanism 2 includes a rubber pad 21. The top of the rubber pad 21 is in contact with the bottom of the connecting ring 31. The bottom of the rubber pad 21 is fixedly connected with a movable rod 22. The bottom end of the movable rod 22 passes through the inner ring of the buffer spring 23 and is slidably connected with the inner wall of the fixed tube 24. The bottom of the fixed tube 24 is fixedly connected in the card slot opened at the top of the filter box 11.

[0026] In this embodiment, the rubber pad 21 can protect the bottom surface of the connecting ring 31 and avoid direct contact between the bottom of the connecting ring 31 and the top of the filter box 11. In addition, after the items to be filtered are loaded into the sintered filter screen 33, the sintered filter screen 33 and the connecting ring 31 will bear the pressure from the items. These pressures will be transmitted to the rubber pad 21 and the movable rod 22. Then, the movable rod 22 will be pressed into the fixed tube 24 under these weights. At the same time, the buffer spring 23 will be subjected to the extrusion force and contract and deform, thereby extending the service life of the sintered filter screen 33 and the connecting ring 31.

[0027] The present invention provides a single-layer mesh sintered stainless steel filter screen, and the specific working principle is as follows:

[0028] When the user needs to disassemble the sintered filter screen 33 to clean the impurities in the filter screen, first open the top cover 34. When the operator presses the pressing block 13, it will generate a thrust force, which will be transmitted to the clamping block 14. When the clamping block 14 receives the thrust force, it will squeeze the S-shaped elastic piece 17. The S-shaped elastic piece 17 is a kind of elastic material. When being squeezed, it will shrink and deform. During this process, the clamping groove opened on the clamping block 14 will slide on the sliding rod 16. The function of the sliding rod 16 is to ensure the horizontal movement track of the clamping block 14 and prevent it from shifting during the movement. Therefore, the clamping block 14 can contact and limit the clamping ring 15, thus ensuring the smooth progress of the disassembly process. The staff can pull the handle 32 to take out the connecting ring 31 and the sintered filter screen from the filter box 11, and then clean the sintered filter screen 33 to remove the impurities in it. When the sintered filter screen 33 contains the items to be filtered, the sintered filter screen 33 and the connecting ring 31 will bear the pressure from the items. These pressures will be transmitted to the rubber pad 21 and the movable rod 22, causing the movable rod 22 to be pressed down into the fixed tube 24 due to the weight. At the same time, the buffer spring 23 will also be squeezed and deformed.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
