It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0026] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0027] Embodiment 1

[0028] Such as Figure 1As shown in FIGS. -7, the present utility model provides an anti-clogging stainless steel mesh liquid filter bag, which includes a stainless steel mesh filter bag 1. An assembly and disassembly mechanism 2 is provided at the upper end of the stainless steel mesh filter bag 1. The assembly and disassembly mechanism 2 includes two groups of L-shaped seats 21 and two groups of special-shaped seats 22. Two groups of ejector posts 23 are slidably installed through the upper ends of the two groups of special-shaped seats 22. Lower stoppers 24 are welded at the inner bottom ends of the two groups of L-shaped seats 21 and at one side edge position. Upper stoppers 25 are welded on the inner side walls of the two groups of L-shaped seats 21 and near the other side edge position. Cavities 28 are formed inside the two groups of special-shaped seats 22. A partition plate 26 is fixedly installed in the middle of the two groups of cavities 28. Two groups of limit blocks 261 are slidably installed through the lower ends of the two groups of special-shaped seats 22. Arc-shaped push plates 27 are slidably installed inside the cavities 28. Two groups of support springs 281 are fixedly installed at the lower ends of the two groups of arc-shaped push plates 27. Three vertical grooves 29 are formed through one side of the partition plate 26. Movable blocks 210 are rotatably installed inside the three vertical grooves 29. Sliding grooves 211 are formed through one ends of the limit blocks 261 and the arc-shaped push plates 27. The lower ends of the two groups of special-shaped seats 22 are fixed to the upper end of the stainless steel mesh filter bag 1. The lower ends of the four ejector posts 23 are respectively fixed to the upper ends of the two groups of arc-shaped push plates 27. The upper parts of the three movable blocks 210 are respectively slidably clamped inside three of the sliding grooves 211. The lower parts of the three movable blocks 210 are respectively slidably clamped inside the other three sliding grooves 211. The lower ends of the four support springs 281 are respectively fixed to the inner bottom ends of the two groups of cavities 28.

[0029] The specific settings and functions of this embodiment will be described in detail below. By providing a disassembly and assembly mechanism 2, when the upper end of the stainless steel mesh filter bag 1 is pushed into the interior of the cylinder 12, the two top columns 23 come into contact with the lower end of the ring seat 11. Continuing to push the two special-shaped seats 22 upward, at this time, the two top columns 23 will move downward through the ring seat 11, and the two top columns 23 push the arc-shaped push plate 27 to move downward inside the cavity 28, while squeezing the four support springs 281. Since the upper and lower parts of the three movable blocks 210 are respectively movably installed inside the six sliding grooves 211, and several protruding ends at the front and rear ends of the three limit blocks 261 are respectively slidably clamped inside the sliding grooves 211, it can act as a guide seat for the three limit blocks 261, so that the length of the three limit blocks 261 can be adjusted, facilitating the movement of the three limit blocks 261 inside the special-shaped seat 22. Therefore, the arc-shaped push plate 27 will drive the limit blocks 261 to move upward inside the special-shaped seat 22 through the three movable blocks 210, and retract the limit blocks 261 inside the special-shaped seat 22. At this time, rotate the stainless steel mesh filter bag 1 so that the two special-shaped seats 22 at its upper end respectively move onto the two lower stoppers 24. When the two special-shaped seats 22 respectively contact the two upper stoppers 25, stop rotating the stainless steel mesh filter bag 1. Under the elastic force of the four support springs 281, the four support springs 281 respectively push the two arc-shaped push plates 27 to move upward inside the two cavities 28. Due to the cooperation between the three movable blocks 210, the partition 26, the limit blocks 261 and the arc-shaped push plate 27, a lever effect is formed. When the arc-shaped push plate 27 moves upward, the arc-shaped push plate 27 drives the limit blocks 261 to move downward through the three limit blocks 261, so that the lower end of the limit blocks 261 contacts the inner bottom end of the L-shaped seat 21. At this time, the two special-shaped seats 22 will be blocked between the two lower stoppers 24 and the two upper stoppers 25, and thus the two special-shaped seats 22 can be fixed inside the two L-shaped seats 21, so that the stainless steel mesh filter bag 1 can be quickly fixed to the lower end of the ring seat 11, and the stainless steel mesh filter bag 1 can be installed. Secondly, by pulling down the stainless steel mesh filter bag 1, the stainless steel mesh filter bag 1 will drive the two special-shaped seats 22 to move downward, and the two special-shaped seats 22 will drive the two limit blocks 261 to move downward together, so that the two limit blocks 261 exert pressure on the L-shaped seat 21. At this time, the upper parts of the two limit blocks 261 will be respectively retracted inside the two special-shaped seats 22. Under the action of the above lever principle, the two limit blocks 261 drive the two arc-shaped push plates 27 to move downward through the six movable blocks 210, so that the two arc-shaped push plates 27 drive the four top columns 23 to contract into the two cavities 28. When the bottom ends of the two special-shaped seats 22 respectively contact the inner bottom ends of the two L-shaped seats 21, rotate the stainless steel mesh filter bag 1 so that it drives the two special-shaped seats 22 to rotate under the lower ends of the two upper stoppers 25, and thus the two special-shaped seats 22 can be removed from between the two lower stoppers 24 and the two upper stoppers 25.Thus, the stainless steel mesh filter bag 1 can be quickly disassembled from the inside of the two groups of L-shaped seats 21. In summary, the replacement of the stainless steel mesh filter bag 1 can be completed without cumbersome steps, which not only saves time and effort, but also does not affect the filtration of the liquid.

[0030] Embodiment 2

[0031] As Figure 1 、 Figure 5 and Figure 6 shown, the anti-blocking mechanism 3 includes a filter cylinder 31 and two groups of concave seats 36 at both ends. Two guiding grooves 33 are opened at the upper end of the stainless steel mesh filter bag 1. The inner bottom ends of the two guiding grooves 33 are both provided with sliding grooves 34. Slide columns 35 are slidably installed inside the two sliding grooves 34. Two L-shaped scraping plates 37 are arranged on the inner wall of the filter cylinder 31. A limiting plate 38 is slidably installed at the upper end of the filter cylinder 31. One ends of the two L-shaped scraping plates 37 are respectively fixed to one end of the limiting plate 38 for you. Among them, the two top columns 23 are respectively inserted into the two concave seats 36 at both ends, and the protruding parts at the lower ends of the two limiting plates 38 are respectively inserted into the two concave seats 36 at both ends.

[0032] The overall effect achieved by this entire embodiment is that by setting the anti-blocking mechanism 3 and setting the filter cylinder 31, when filtering water, the impurities in the water will be blocked by the filter cylinder 31, so that the water and the impurities are separated, thereby being able to filter the impurities in the water, preventing the impurities from entering the inside of the stainless steel mesh filter bag 1 along with the water, preventing the stainless steel mesh filter bag 1 from being blocked, and not affecting the filtration efficiency of the stainless steel mesh filter bag 1. Secondly, by repeatedly moving the two special-shaped seats 22, the two special-shaped seats 22 drive the two concave seats 36 at both ends to move through the two top columns 23. Since the concave seats 36 at both ends are slidably installed inside the two sliding grooves 34 through the two slide columns 35, the concave seats 36 at both ends move repeatedly inside the two sliding grooves 34. Then, the protruding parts at one ends of the two L-shaped scraping plates 37 are slidably inserted into the card slots of the filter cylinder 31, which is convenient for the two concave seats 36 at both ends to drive the two L-shaped scraping plates 37 to move, so that the two L-shaped scraping plates 37 can conveniently scrape the inner wall of the filter cylinder 31, and the solid substances stuck in the filter slots of the filter cylinder 31 can be pushed out, preventing the solid substances from blocking the filter slots in the filter cylinder 31. And by setting the circular ring diversion seat 32, the water flowing in can be diverted and the upper end of the filter cylinder 31 can be blocked.

[0033] Embodiment 3

[0034] As Figure 1 and Figure 5 shown, a circular ring seat 11 is sleeved on the upper part of the stainless steel mesh filter bag 1. A cylinder 12 is fixedly installed at the lower end of the circular ring seat 11. The upper ends of the two groups of L-shaped seats 21 are respectively fixed to the lower end of the circular ring seat 11. The lower part of the stainless steel mesh filter bag 1 is inserted into the inside of the cylinder 12.

[0035] The effect achieved by the entire embodiment is that by providing the circular ring seat 11 and the cylinder 12, the cylinder 12 can protect the stainless steel mesh filter bag 1 and prevent damage to the stainless steel mesh filter bag 1 caused by external factors. The circular ring seat 11 can facilitate the assembly with the port of the liquid filter.

[0036] Usage method and working principle of this device: First, install the ring seat 11 onto the port of the liquid filter, then push the upper end of the stainless steel mesh filter bag 1 into the interior of the cylinder 12, so that the two sets of top columns 23 contact the lower end of the ring seat 11. Continue to push the two sets of special-shaped seats 22 upward. At this time, the two sets of top columns 23 will move downward through the ring seat 11, and the two sets of top columns 23 push the arc-shaped push plate 27 to move downward inside the cavity 28, while squeezing the four sets of support springs 281. And because the upper and lower parts of the three sets of movable blocks 210 are respectively movably installed inside the six sets of sliding grooves 211, and several protruding ends at the front and rear ends of the three sets of limiting blocks 261 are respectively slidably clamped inside the sliding grooves 211, it can act as a guiding seat for the three sets of limiting blocks 261, so that the lengths of the three sets of limiting blocks 261 can be adjusted, facilitating the three sets of limiting blocks 261 to move inside the special-shaped seat 22. Therefore, the arc-shaped push plate 27 will drive the limiting block 261 to move upward inside the special-shaped seat 22 through the three sets of movable blocks 210, and contract the limiting block 261 inside the special-shaped seat 22. At this time, rotate the stainless steel mesh filter bag 1 so that the two sets of special-shaped seats 22 at its upper end respectively move onto the two sets of lower stoppers 24. When the two sets of special-shaped seats 22 respectively contact the two sets of upper stoppers 25, stop rotating the stainless steel mesh filter bag 1. Under the elastic force of the four sets of support springs 281, the four sets of support springs 281 respectively push the two sets of arc-shaped push plates 27 to move upward inside the two sets of cavities 28. Due to the cooperation among the three sets of movable blocks 210, the partition plate 26, the limiting block 261 and the arc-shaped push plate 27, a lever effect is formed. When the arc-shaped push plate 27 moves upward, the arc-shaped push plate 27 drives the limiting block 261 to move downward through the three sets of limiting blocks 261, so that the lower end of the limiting block 261 contacts the inner bottom end of the L-shaped seat 21. At this time, the two sets of special-shaped seats 22 will be blocked between the two sets of lower stoppers 24 and the two sets of upper stoppers 25, and thus the two sets of special-shaped seats 22 can be fixed inside the two sets of L-shaped seats 21, and the stainless steel mesh filter bag 1 can be quickly fixed to the lower end of the ring seat 11, enabling the installation of the stainless steel mesh filter bag 1. Then, through the setting of the filter cylinder 31, when filtering water, the impurities in the water will be blocked by the filter cylinder 31, separating the water from the impurities, thereby being able to filter the impurities in the water, preventing the impurities from entering the interior of the stainless steel mesh filter bag 1 along with the water, preventing blockage of the stainless steel mesh filter bag 1, and not affecting the filtering efficiency of the stainless steel mesh filter bag 1. Secondly, repeatedly move the two sets of special-shaped seats 22, so that the two sets of special-shaped seats 22 drive the two sets of concave-ended seats 36 through the two sets of top columns 23. Since the concave-ended seats 36 are slidably installed inside the two sets of sliding grooves 34 through the two sets of sliding columns 35, the concave-ended seats 36 respectively move repeatedly inside the two sets of sliding grooves 34. Then, one end protrusion of the two sets of L-shaped scraping plates 37 is slidably inserted into the card slots of the filter cylinder 31, facilitating the two sets of concave-ended seats 36 to drive the two sets of L-shaped scraping plates 37 to move, and being able to conveniently scrape the inner wall of the filter cylinder 31 by the two sets of L-shaped scraping plates 37.The solid matter stuck in the filter grooves of the filter cartridge 31 can be pushed out. Finally, when it is necessary to replace the stainless steel mesh filter bag 1, by pulling down the stainless steel mesh filter bag 1, the stainless steel mesh filter bag 1 will drive the two groups of special-shaped seats 22 to move downward, and the two groups of special-shaped seats 22 will drive the two groups of limit blocks 261 downward together, so that the two groups of limit blocks 261 exert pressure on the L-shaped seat 21. At this time, the upper parts of the two groups of limit blocks 261 will contract respectively inside the two groups of special-shaped seats 22. Under the action of the above lever principle, the two groups of limit blocks 261 drive the two groups of arc-shaped push plates 27 to move downward through the six groups of movable blocks 210, so that the two groups of arc-shaped push plates 27 drive the four groups of ejector posts 23 to contract into the two groups of cavities 28. When the bottoms of the two groups of special-shaped seats 22 are respectively in contact with the inner bottoms of the two groups of L-shaped seats 21, rotate the stainless steel mesh filter bag 1 to drive the two groups of special-shaped seats 22 to rotate at the lower ends of the two groups of upper stoppers 25, and the two groups of special-shaped seats 22 can be removed from the middle of the two groups of lower stoppers 24 and the two groups of upper stoppers 25, and the stainless steel mesh filter bag 1 can be quickly disassembled from the inside of the two groups of L-shaped seats 21.,

[0037] The above is only the preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.,
