This filter has a simple structure, is easy to use and install, simple to operate, has good filtration effect, can circulate and filter, has high filtration efficiency, a wide range of applications, a long service life, and is safe and reliable. However, as can be seen from the above, although this filter can be well applied for filtering water sources, it is usually not easy to quickly open the filter, and therefore not easy to clean and maintain. Further improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to provide a circulating water filter to solve the problem mentioned in the background art that although the filter can be used well to filter water sources, it is usually not easy to quickly open the filter, and therefore it is not easy to clean and maintain the filter.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a circulating water filter, comprising a filter cylinder, a cylinder seat fixed to the top of the filter cylinder, a cylinder cover inserted into the cylinder seat, a cover handle at the center of the top of the cylinder cover, an injection port on the top of the cylinder cover on one side of the cover handle, a shaft seat fixedly mounted on the outer wall of one side of the cylinder seat by a bracket, an L-shaped shaft rotatably mounted inside the shaft seat, one end of the L-shaped shaft extending to the outside of the shaft seat and having a nut seat, a screw threaded inside the nut seat, the bottom end of the screw extending to the outside of the nut seat and having a pressure block mounted thereon, the bottom end of the pressure block contacting the top of the cylinder cover, a drain valve pipe mounted on the lower outer wall of one side of the filter cylinder, a pressure gauge mounted on the upper outer wall of one side of the filter cylinder, and a filter screen installed inside the filter cylinder.

[0006] Preferably, a second circulation valve is provided on the inner wall of the filter cylinder above the filter screen. One end of the second circulation valve extends to the outside of the filter cylinder and is equipped with a second circulation pipe. The second circulation valve is provided to allow the second circulation pipe to be opened and closed.

[0009] Preferably, the filter cylinder above the lower sealing plate is provided with an upper sealing plate, and the lower sealing plate is provided with a plurality of placement cylinders, which are used to place the uniformly distributed pipe.

[0010] Preferably, each of the placement cylinders is equipped with a distribution pipe. The top end of the distribution pipe extends to the outside of the placement cylinder and passes through the upper sealing plate. The bottom end of the distribution pipe extends to the outside of the placement cylinder and is equipped with a distribution nozzle. The distribution nozzle is used to distribute the water source evenly to the top of the filter screen.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the circulating water filter not only improves the convenience of filter maintenance, but also ensures the filtration effect of the filter on the water source during use, and achieves the purpose of easy circulation filtration of the water source.

[0012] (1) By turning the screw, the screw rotates inside the nut seat and slides upward to move the pressure block to the outside of the cover handle. Then, rotate the L-shaped shaft so that the lower end of the L-shaped shaft is inside the shaft seat and rotates to move the L-shaped shaft away from the top of the cylinder cover. At this time, pull the cover handle upward to remove the cylinder cover to the outside of the cylinder seat, so as to quickly and conveniently open the filter, thereby improving the convenience of filter maintenance.

[0013] (2) Water is injected into the filter cylinder through the injection port. Because the upper and lower sealing plates place several evenly distributed pipes inside the filter cylinder, the water at the top of the filter cylinder is evenly distributed to the top of the filter screen through several evenly distributed pipes and evenly distributed through the evenly distributed nozzles. The filter screen can then perform efficient filtration of the water, thus ensuring the filtration effect of the filter on the water when it is in use.

[0014] (3) By opening the first circulation valve and the second circulation valve, and then starting the circulation pump, the water source at the lower end of the filter cylinder can be transported to the filter cylinder above the filter screen through the first circulation pipe and the second circulation pipe. Then the filter screen can filter the water source again, thereby achieving the purpose of easy circulation filtration of the water source, so as to further ensure the filtration effect of the filter on the water source.

[0021] Please see Figure 1-4 This utility model provides an embodiment of a circulating water filter, including a filter cylinder 1, a cylinder base 2 fixed to the top of the filter cylinder 1, a cylinder cover 24 inserted into the cylinder base 2, a cover handle 10 at the center of the top of the cylinder cover 24, a liquid injection port 23 on the top of the cylinder cover 24 on one side of the cover handle 10, a shaft seat 11 fixedly mounted on the outer wall of one side of the cylinder base 2 by a bracket, an L-shaped shaft 12 rotatably mounted inside the shaft seat 11, one end of the L-shaped shaft 12 extending to the outside of the shaft seat 11 and having a nut seat 13. A screw 14 is installed on the internal thread of the nut seat 13. The bottom end of the screw 14 extends to the outside of the nut seat 13 and is fitted with a pressure block 15. The bottom end of the pressure block 15 contacts the top end of the cylinder cover 24. A drain valve pipe 3 is installed on the lower outer wall of one side of the filter cylinder 1. A pressure gauge 9 is installed on the upper outer wall of one side of the filter cylinder 1. A filter screen 16 is installed inside the filter cylinder 1. A second circulation valve 6 is provided on the inner wall of the filter cylinder 1 above the filter screen 16. One end of the second circulation valve 6 extends to the outside of the filter cylinder 1 and is fitted with a second circulation pipe 5.

[0022] In use, the second circulation valve 6 is set to open and close the second circulation pipe 5.

[0023] A circulation pump 4 is installed at the bottom of the second circulation pipe 5. The circulation pump 4 is connected to the outer wall of the filter cylinder 1 through a bracket. A first circulation pipe 7 is installed at the end of the circulation pump 4 away from the second circulation pipe 5. A first circulation valve 8 is installed at the end of the first circulation pipe 7 away from the circulation pump 4. The end of the first circulation valve 8 away from the first circulation pipe 7 is connected to the outer wall of the filter cylinder 1.

[0024] In use, the first circulation valve 8 is set to open and close the first circulation pipe 7.

[0025] An annular support seat 17 is fixed on the inner wall of the filter cylinder 1 above the second circulation valve 6, and a lower sealing plate 18 is installed inside the filter cylinder 1 above the annular support seat 17.

[0026] In use, the annular support seat 17 is provided to support the lower sealing plate 18.

[0027] The filter cylinder 1 above the lower sealing plate 18 is provided with an upper sealing plate 19, and the lower sealing plate 18 is provided with a number of placement cylinders 20.

[0028] In use, the placement cylinder 20 is used to accommodate the uniform distribution pipe 21.

[0029] The inside of each component cylinder 20 is equipped with a uniform distribution tube 21. The top end of the uniform distribution tube 21 extends to the outside of the component cylinder 20 and passes through the upper sealing plate 19. The bottom end of the uniform distribution tube 21 extends to the outside of the component cylinder 20 and is equipped with a uniform distribution nozzle 22.

[0030] When in use, the water source is evenly distributed on the top of the filter screen 16 by setting the evenly distributed nozzle 22.

[0031] In this embodiment, water is first injected into the filter cylinder 1 through the injection port 23. Because the upper sealing plate 19 and lower sealing plate 18 house several evenly distributed pipes 21 inside the filter cylinder 1, the water at the upper end of the filter cylinder 1 is evenly distributed to the top of the filter screen 16 via the evenly distributed pipes 21 and the evenly distributed nozzles 22. The filter screen 16 then efficiently filters the water. Afterwards, by opening the first circulation valve 8 and the second circulation valve 6, and then starting the circulation pump 4, the water at the lower end of the filter cylinder 1 is transported to the filter cylinder 1 above the filter screen 16 via the first circulation pipe 7 and the second circulation pipe 5. The filter screen 16 then filters the water again, facilitating further filtration. The water source undergoes a circulating filtration process. Finally, by turning the screw 14, the screw 14 rotates inside the nut seat 13 and slides upward, moving the pressure block 15 to the outside of the cover handle 10. Then, the L-shaped shaft 12 is rotated, so that the lower end of the L-shaped shaft 12 rotates inside the shaft seat 11, moving the L-shaped shaft 12 away from the top of the cylinder cover 24. At this time, pulling the cover handle 10 upward allows the cylinder cover 24 to be removed to the outside of the cylinder seat 2, enabling quick and convenient opening and maintenance of the filter. Furthermore, since the lower sealing plate 18 is overlapped and placed on the top of the annular support seat 17, the lower sealing plate 18 and other related evenly distributed components can be pulled upward for disassembly, thus completing the use of the filter.
