DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figures 1 to 5 As shown, an anti-blocking valve provided by an embodiment of the utility model includes:

[0027] A connecting valve 1 is provided, an arc groove 2 is provided on the left side of the connecting valve 1, a circular ring 3 is provided inside the connecting valve 1, the circular ring 3 is located inside the arc groove 2, the circular ring 3 and the arc groove 2 are slidably installed, four groups of placement grooves 4 are provided on the left side of the connecting valve 1, and a first filter cartridge 5 is fixedly installed on the surface of the circular ring 3;

[0028] The first filter cartridge 5 is a filter element with a relatively small filter hole. The first filter cartridge 5 can effectively filter out the larger impurities in the water, and the filtered impurities will remain in the first filter cartridge 5.

[0029] A second filter cartridge 12 is disposed inside the first filter cartridge 5, and the right side of the second filter cartridge 12 contacts the right side of the inner wall of the first filter cartridge 5;

[0030] The second filter cartridge 12 is a filter element with a larger filter hole. When the left side of the connecting valve 1 is connected to the water outlet pipe, water will enter the connecting valve 1. Then, the water will first pass through the second filter cartridge 12 to filter out the larger impurities inside. After filtering, the smaller impurities will also be filtered through the first filter cartridge 5, thereby preventing the impurities in the water from clogging the connecting valve 1 and preventing it from being used normally.

[0031] The limiting component 6 is located inside the placement groove 4 , and the right side of the limiting component 6 contacts the left side of the circular ring 3 . The limiting component 6 is used to limit the circular ring 3 to be installed inside the arc groove 2 .

[0032] Fix the ring 3 and the first filter cartridge 5 together, and then place the ring 3 into the placement groove 4. The ring 3 will drive the filter assembly to enter the connecting valve 1. Then, the ring 3 will be limited by the limit assembly 6. Then, the left side of the connecting valve 1 and the water outlet pipe will be installed. After installation, water will enter the connecting valve 1. At this time, the second filter cartridge 12 will filter the larger impurities in the water. Then, the water filtered by the second filter cartridge 12 will also pass through the first filter cartridge 5 to filter the smaller impurities inside it, thereby preventing the connecting valve 1 from being blocked.

[0033] A threaded tube 10 is fixedly installed on the right side of the first filter cartridge 5 , a threaded rod 11 is fixedly installed on the right end of the second filter cartridge 12 , the right end of the threaded rod 11 penetrates into the interior of the threaded tube 10 , and the threaded rod 11 and the threaded tube 10 are threadedly installed.

[0034] Through the mutual cooperation of the threaded tube 10 and the threaded rod 11, the second filter cartridge 12 can be placed inside the first filter cartridge 5. At this time, the second filter cartridge 12 can be rotated, and the second filter cartridge 12 drives the threaded tube 10 to rotate. The threaded rod 11 rotates and gradually enters the threaded tube 10, thereby limiting the second filter cartridge 12 and preventing the second filter cartridge 12 from being separated from the first filter cartridge 5 during operation.

[0035] A hollow scraper 7 is disposed inside the second filter cartridge 12 . The surface of the hollow scraper 7 contacts the inner wall of the second filter cartridge 12 . A stabilizing rod 8 is fixedly mounted on the left side of the hollow scraper 7 .

[0036] Through the cooperation between the hollow scraper 7 and the stabilizing rod 8, when there are too many larger impurities inside the second filter cartridge 12, the water outlet pipe and the connecting valve 1 can be separated, and then the stabilizing rod 8 can be pulled to the left. The movement of the stabilizing rod 8 drives the hollow scraper 7 to move to the left. The movement of the hollow scraper 7 to the left can pull out the larger impurities inside the second filter cartridge 12, thereby cleaning the second filter cartridge 12.

[0037] A cover plate 9 is provided on the left side of the second filter cartridge 12 , one side of the cover plate 9 contacts the left side of the first filter cartridge 5 , the cover plate 9 and the first filter cartridge 5 are threadedly installed, and the right side of the cover plate 9 contacts the left end of the stabilizing rod 8 .

[0038] By setting the cover plate 9, the stabilizing rod 8 can be limited to prevent the stabilizing rod 8 and the hollow scraper 7 from shaking due to excessive water pressure inside the connecting valve 1 when the stabilizing rod 8 is not working.

[0039] The limiting assembly 6 includes limiting blocks 61, and the number of limiting blocks 61 is four groups. The inner side of the limiting block 61 contacts the left side of the ring 3, and the right side of the limiting block 61 is located inside the placement groove 4. The limiting block 61 and the placement groove 4 are slidably installed.

[0040] By setting the limit block 61, the limit block 61 can be pushed inward at the same time to contact the left side of the ring 3, so that the ring 3 can be limited to prevent the ring 3 and the arc groove 2 from being separated, thereby causing the ring 3, the first filter cartridge 5 and the second filter cartridge 12 to be unable to continue to filter the water entering the inside of the connecting valve 1.

[0041] A limiting rod 62 is fixedly installed on the inner wall of the placement groove 4. The inner end of the limiting rod 62 penetrates into the inner side of the limiting block 61. The limiting rod 62 and the limiting block 61 are slidably installed.

[0042] By setting the limiting rod 62 , the limiting block 61 can be limited to prevent the limiting block 61 from being separated from the placement groove 4 when moving, thereby causing the limiting block 61 to be unable to continue to limit the ring 3 .

[0043] A limiting tension spring 63 is sleeved on the surface of the limiting rod 62 , the outer end of the limiting tension spring 63 is fixedly installed on the inner side of the limiting block 61 , and the inner end of the limiting tension spring 63 is fixedly installed on the inner wall of the placement slot 4 .

[0044] By providing the limiting tension spring 63 , the limiting block 61 can always be subjected to the tension of the limiting tension spring 63 , so that the limiting block 61 can be more stable when limiting the ring 3 .

[0045] The above embodiments are only used to help understand the method and core idea of ​​the utility model. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made to the utility model without departing from the principle of the utility model, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
