Description

Technical Field

[0001] The utility model relates to the technical field of drinking water filtration, in particular to a drinking water filtration device. Background Art

[0002] Drinking water refers to water that can be directly supplied to the human body without treatment. Water is the main component of body fluids and an important substance that constitutes cells, tissue fluid, plasma, etc. As a medium for all chemical reactions in the body and a platform for the transportation of various nutrients and substances, when drinking water is stored for a long time, some impurities will appear in the water, and a purification device is required for filtration. Therefore, a drinking water filtration and purification device is needed.

[0003] Although the existing drinking water filtration and purification devices can filter impurities in water during use, the internal filter media impurities are easily blocked after long-term use, resulting in a reduction in the water output and the need for replacement. However, the steps for disassembling and replacing the filter media are cumbersome and difficult to disassemble. Moreover, for easy disassembly, the device needs to be moved to a slightly more open place. Due to the lack of rollers for assisting the movement of the device, it is more laborious to move.
