Bacteriostatic filter element

Abstract

According to the antibacterial filter element provided by the invention, antibacterial substances in the antibacterial filter element are granular, can float and roll in a certain space under the action of water flow, and are in full contact with the water flow, so that the bacteriostasis is more sufficient, and meanwhile, the overall utilization rate of the antibacterial substances is also improved. A filling area and a turbulent flow area are arranged in the central pipe, and the filling area is filled with the antibacterial particles; when the antibacterial filter element works, water flow enters the flow passing channel from the water inlet end, and the antibacterial particles turn over towards the turbulent flow area from the filling area along with the water flow, so that the antibacterial particles float in the flow passing channel in a free manner, the antibacterial particles continuously sterilize along with the water flow, and the continuous sterilization can bring a better antibacterial effect; the water passing through the antibacterial particles is high in antibacterial property, and the number of bacterial colonies is lower.

Description

technical field [0001] The invention relates to the field of household water purification, in particular to an antibacterial filter element. Background technique [0002] In the current household water purifiers on the market, most of the pure water filtered by the reverse osmosis filter element adopts the rear activated carbon filter element to further improve the taste. However, activated charcoal tends to breed bacteria after prolonged use. This will lead to the fact that the number of colonies in the pure water filtered by the reverse osmosis filter element is low, due to the fact that the colony is too high after the activated carbon that breeds bacteria. In other words, the activated carbon that produces bacteria contaminates the reverse Pure water filtered by an osmotic filter element. [0003] The rear activated carbon filter basically adopts a single external activated carbon filter or is compounded at the rear end of the reverse osmosis filter. The above are all ...

Problems solved by technology

This fixed molding method will compact the carbon. In the case of compacted activated carbon, the gap between the particles is small, and the pressure at the beginning of the water flow into the carbon will be relatively high, which will also cause the pressure difference of the reverse osmosis membrane unit. Smaller, if the pure water is contaminated with bacteria, the bacteria will adhere to the pure water side of the reverse osmosis membrane, and instead produce organic matter on the pure water side of the reverse osmosis membrane, thereby contaminating the reverse osmosis membrane

Even if antibacterial substances are added to this fixed activated carbon, due to this fixed form, the antibacterial substances cannot fully exert their effect and cannot form a full range of effective sterilization. If the pressure difference at the end of the filter is too large, the part at the beginning of the filter will lose much more than the part at the end of the filter, which will also have a negative effect on the bactericidal effect
