Description

Technical Field

[0001] This utility model relates to the field of drinking water filtration equipment, and in particular to a drinking water filtration device, belonging to the field of water treatment technology. Background Technology

[0002] Drinking water filtration devices are water treatment equipment that performs deep filtration and purification of water according to the requirements of water use. Their function is to filter out floating matter, heavy metals, bacteria, viruses, residual chlorine, sediment, rust and microorganisms in water. The pre-filter is the first coarse filtration device in a household or commercial drinking water system, which can effectively filter out large particles such as sediment, rust, insect eggs and red worms in tap water. Therefore, it requires a higher cleaning frequency.

[0003] Chinese Patent Publication No. CN222238971U discloses a self-cleaning water purifier filter device, including a housing. One side of the housing is connected to a water inlet pipe, the other side to a drain pipe, and a sewage pipe is connected to the bottom of the housing. A handle is provided on the outside of the housing. This self-cleaning water purifier filter device, by providing a handle, allows a linkage rod to rotate, thereby rotating a movable plate. When the movable plate is above the water inlet pipe, the filter device is in filtration mode; when the movable plate is below the water inlet pipe, it is in self-cleaning mode. In filtration mode, water enters the housing from below the movable plate, passes through the filter screen, and is discharged through the drain pipe. In self-cleaning mode, water enters the housing from above the movable plate, so the water first reaches the side of the filter screen closest to the drain pipe, then passes through the filter screen, rinsing it. Wastewater is discharged through the sewage pipe, offering the advantages of easy cleaning.

[0004] However, existing drinking water filtration devices rely on a self-cleaning water flow structure, which is insufficient to thoroughly rinse away the tiny particles and bacteria remaining in the filter screen, leading to a decline in the quality of purified water. Therefore, it is necessary to replace the filter screen in a timely manner. To address this, a drinking water filtration device is proposed. Utility Model Content
