The sewage discharge pipe 71 communicates the inside of the filter main body 1 with the space below the base 3. When the filter core 44 is replaced, the lower end sewage discharge valve 72 can be opened. In this way, the scale and impurities accumulated in the inside of the filter main body 1 can be flushed and cleaned by manually using a spray gun from the top. The sewage will flow out along the lower end sewage discharge pipe 71. The lower end of the sewage discharge pipe 71 is fixedly connected with the sewage discharge valve 72. The upper end of the sewage discharge pipe 71 is connected with the lower end of the filter core 44.

[0029] Working principle: The new disassembly and replacement of filter cartridge filter is used for household water purification and adsorption treatment, the main function is to purify water quality, remove harmful substances in water, such as bacteria, viruses, heavy metals, residual chlorine, particulate impurities, etc., to ensure the safety and health of drinking water;

[0030] The filter cartridge replacement installation structure of the new disassembly and replacement of filter cartridge filter:

[0031] The sealing groove 41 adopts a stainless steel metal groove embedded in the inside of the filter main body 1, and the matching layer 42 is also made of metal material. The diameter of the reserved space in the matching layer 42 is consistent with the diameter of the filter cartridge 44. In this way, the filter cartridge 44 can be directly inserted into the space inside the matching layer 42 for fixation. The filter cartridge 44 is made of compressed coconut shell activated carbon sintered activated carbon material, which can effectively adsorb residual chlorine, odor, organic matter and part of heavy metals, and improve the taste. When disassembling and replacing the filter cartridge, only need to twist the inside of the screw thread 43 of the top end, and the inside filter cartridge 44 can be taken out by pulling out the installation pipe 45 driven by the top cover 2.

The sealing ring 52 is made of rubber material, which is filled in the connection position of the water inlet pipe 51 and the filter main body 1 to reduce the leakage.

[0034] After the water flow conveyed by the water inlet pipe 51 enters the inside of the filter main body 1, because the filter cartridge 44 is isolated in the middle of the filter main body 1, the flowing water will pass through the filter cartridge to the middle position. In this way, the water passing through the filter cartridge 44 will be adsorbed and purified, and the outside of the filter cartridge 44 is dirty water without purification. The water pump 54 can generate suction along the water suction pipe 53 after being powered on to suck away the filtered water and lead out. The water suction pipe 53 is inserted into the middle position of the filter cartridge 44 to suck away the filtered water and discharge along the water outlet pipe 55. In this way, clean water source can be normally used.

[0035] The drain pipe 71 is connected with the inside of the filter main body 1 and the space below the base 3. The lower end drain valve 72 can be opened at the same time when the filter cartridge 44 is replaced. In this way, the accumulated water scale and impurities in the inside of the filter main body 1 can be flushed and cleaned by using the spray gun manually. The sewage will flow out along the lower end drain pipe 71, which can effectively ensure the cleanliness of the inside of the filter and reduce harmful substances.
