Description

TECHNICAL FIELD

[0001] The present application relates to a composite water purification filter core structure with bacterial growth inhibition. BACKGROUND

[0002] At present, water resource shortage has become a topic that cannot be ignored in today's society, and the phenomenon of wasting water resources is common. At the same time, the continuous improvement of people's living standards makes people's requirements for water quality also increase, and some water that can be used again is directly discarded. With the emergence of water purifiers, this phenomenon has been alleviated, and people have gradually begun to accept the water flow purified from the water purifier. However, the existing purifier not only has high cost consumption, but also has low water purification efficiency, which obviously cannot meet the needs of people now.

[0003] People's requirements for the safety of drinking water mainly reflect two aspects: one is the safety of chemical substances in drinking water; the other is the safety of microorganisms in drinking water. Bacteriological indicators, sensory indicators and toxic and harmful substances have also become several water quality indicators that modern water supply enterprises focus on. Because harmful microorganisms transmitted in water can cause a large number of people to be ill or die in a short time, bacteriological indicators have extremely important position; the principle of determining toxic and harmful substance indicators is that people long-term intake of drinking water with health risks is not easy to detect, and long-term accumulation can cause chronic diseases or cancer; sensory indicators can reflect the overall pollution of water body to a certain extent, which may not cause harm to health, but will cause the drinker to worry about water quality safety.

[0004] The water purification filter core includes a shell and a filter material, and the filter material is generally some filter core belonging to interception filter material, such as PP cotton, ceramic, stainless steel mesh, ultrafiltration, RO membrane, etc. Among them, the PP cotton filter core is widely used, and the PP cotton filter core generally needs to be disassembled and replaced after reaching the use limit. The existing filter core structure has the following disadvantages:

[0005] ①The PP cotton filter core is installed in the shell, and the end cover is threadedly installed on the shell port. When the PP cotton filter core in the shell needs to be replaced, the end cover needs to be screwed with great force. The end cover and the shell port are threadedly connected, and it is relatively laborious to assemble and disassemble. The PP cotton filter core is inconvenient to replace.
