When the filter element assembly 10 needs to be replaced, the filter element housing 101 in the tank body 20 can be taken out only by detaching the buckle 6022-1 from the clamp 6021, separating the first sub-clamp 6021-1 from the second sub-clamp 6021-2, screwing out the joint assembly 30, and detaching the disk body 6011, so that the activated carbon particles 70 in the filter element housing 101 are replaced. After the activated carbon particles 70 in the filter element housing 101 are replaced, when the filter element housing 101 is installed in the tank body 20, the filter element housing 101 is only required to be replaced in the filter element housing 105, the disc body 6011 is replaced at the opening 201, the joint assembly 30 is screwed into the disc body 6011, then the first sub-clamping hoop 6021-1 and the second sub-clamping hoop 6021-2 are screwed up through the clamping buckle 6022-1, the replacement and the installation of the filter element assembly 10 can be completed once, the operation is simple and convenient, the water leakage phenomenon generated in the process of replacing the filter element assembly 10 is avoided, and the user experience is improved. And, by periodically replacing the cartridge assembly 10, the service life of the water purification apparatus is prolonged.

The water purification device that this application embodiment provided, but wide application in various equipment that need purify water, if: water purifier, water fountain, humidifier, etc.

After the water quality purifying device is used for a period of time, certain impurities and pollutants can be accumulated in the tank body 20, regular forward washing and reverse washing are required for the water quality purifying device, and the service life of the water quality purifying device is prolonged.
