[0021] Please see Figure 1-3 This utility model provides a technical solution: a water purification device that facilitates the replacement of water purification filter cartridges, including a water purification tank 1, a tank cover 2 rotatably disposed on the top side of the water purification tank 1, a quick-release mechanism 3 disposed inside the top of the tank cover 2, a filter cartridge 4 installed at the bottom of the inner cavity of the water purification tank 1, a filter cartridge 6 disposed inside the filter cartridge 4, and the quick-release mechanism 3 disposed on the top of the filter cartridge 4.

[0022] The quick-release mechanism 3 includes a handwheel shaft 31 and a sealing cover 34. A threaded cylinder 33 is fixedly connected to the upper surface of the sealing cover 34. A threaded block 32 that is threadedly connected to the threaded cylinder 33 is fixedly connected to the lower end of the handwheel shaft 31. An inner column 341 and an outer ring 342 for limiting the filter element 6 are fixedly connected to the top of the inner cavity of the sealing cover 34. Two sets of telescopic sleeve rods 35 are fixedly connected to the upper surface of the sealing cover 34. The upper ends of the two sets of telescopic sleeve rods 35 are fixedly connected to the top of the inner cavity of the sealing cover 34.

[0023] An inlet pipe 9 penetrating the water tank 1 is provided on the outside of the sealing cover 34. An annular water channel 343 is provided inside the sealing cover 34. Multiple sets of connecting holes 344 connected to the annular water channel 343 are provided at the top of the inner cavity of the sealing cover 34. The annular water channel 343 and the connecting holes 344 facilitate water flow into the filter cartridge 4 and make the water flow uniform, reducing the impact on the filter element 6, thereby improving the service life of the filter element 6.

[0024] A drain pipe 10 is provided at one end of the water inlet pipe 9 located outside the water purification tank 1. A bidirectional pipe 41 is provided at the bottom of the filter cartridge 4, which penetrates the water purification tank 1. A water outlet pipe 7 and a backwash pipe 8 are provided at one end of the bidirectional pipe 41 located outside the water purification tank 1. The bidirectional pipe 41 facilitates the limiting of the filter element 6 while facilitating the outflow of purified water. The backwash pipe facilitates the backwashing of the filter element 6, thereby reducing the number of times the filter element 6 needs to be replaced and improving the service life of the filter element 6.

[0025] A second sealing ring 11 is provided at the top of the inner cavity of the sealing cover 34. The second sealing ring 11 is located between the inner column 341 and the outer ring 342. The second sealing ring 11 abuts against the top of the filter element 6. The second sealing ring 11 improves the sealing performance between the sealing cover 34 and the filter element 6. The outer ring 342 and the inner column 341 improve the stability of the filter element 6 installation.

[0026] The bottom of the inner cavity of the filter cartridge 4 is provided with a first sealing ring 5 that abuts against the filter element 6. A support ring 42 is fixedly connected to the bottom of the inner cavity of the filter cartridge 4. The filter element 6 is placed inside the support ring 42. The first sealing ring 5 improves the sealing between the filter cartridge 4 and the filter element 6.

The outer diameter of the filter element 6 is smaller than the inner diameter of the filter cylinder 4. A water inlet chamber is provided between the filter cylinder 4 and the filter element 6, and a drain chamber is provided between the filter element 6 and the bidirectional pipe 41. By utilizing the water inlet chamber and the drain chamber formed between the filter cylinder 4 and the filter element 6, the water filtration area is increased, thereby facilitating water filtration and purification and improving the water purification effect.

[0028] The cover 2 has multiple sets of latches on one side. The axis of the sealing cover 34 and the axis of the filter cartridge 4 are both on the same axis. The latches make it easy to open and close the cover 2. The structure is simple and reduces the cost of the equipment.

[0029] In use, rotating the handwheel shaft 31 drives the threaded block 32 to rotate, thereby causing the threaded block 32 to rotate inside the threaded cylinder 33. Under the limiting action of the telescopic sleeve rod 35, the threaded cylinder 33 moves linearly along the handwheel shaft 31, thereby causing the sealing cover 34 to disengage from the filter cartridge 4, improving the opening efficiency of the sealing cover 34. Opening the latch of the box cover 2 makes it easy to move the quick-release mechanism 3 away from the filter cartridge 4, and facilitates the removal of the filter element 6 inside the filter cartridge 4 for cleaning or replacement, improving the replacement efficiency. After replacement, close the box cover 2, and rotate the handwheel shaft 31 in the opposite direction to bring the sealing cover 34 closer to the filter cartridge 4, thereby completing the sealing of the filter cartridge 4, so that the water inlet equipment can continue to be used, improving the efficiency of replacing the filter element 6 of the water inlet equipment.
