Description

Technical Field

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

[0002] Drinking water refers to water sources suitable for human drinking and domestic use. It is one of the essential resources in people's daily lives. Drinking water should meet certain hygiene standards and be safe and harmless for people to drink. Generally, drinking water can come from multiple sources, including tap water, well water, river water, lake water, groundwater, etc. After these water sources are treated and purified, potential pollutants and harmful substances are removed to ensure that the water quality meets hygiene standards. Drinking water is essential for human health. It nourishes the body, maintains normal physiological functions, and helps digestion and metabolize waste. Tap water is the main source of drinking water for modern people. However, as time goes by, aging, corrosion or pollution of water supply pipes will cause tap water to become dirty. Sediment, bacteria or heavy metals in the pipes will affect the water quality. In order to improve the purity of tap water, it needs to be purified before people use it. At present, multi-stage filtration is usually used for tap water purification. The fine filter of the primary filtration will intercept large particles of impurities in the tap water, such as mud and pipe sediments. As the purification process proceeds, these impurities will adhere to the filter, causing the filter to be blocked and the water pressure to drop, affecting people's water needs. Although some drinking water purification devices on the market have self-cleaning functions, such as recoil drinking water purification devices, which use recoil to clean the filter, their cleaning method is single, and some firmly attached impurities and pollutants in the pipe are difficult to clean up. There are also problems of filter blockage and water pollution when used for a long time. Utility Model Content
