Because the filter element inside the water purifier can filter and purify the water, the treated water can meet the national drinking water hygiene and health standards.
[0003] After long-term use, the reverse osmosis effect of the filter will gradually decline, and the reverse osmosis membrane in the filter needs to be replaced. However, when replacing the reverse osmosis membrane of the existing filter, the filter housing needs to be disassembled, and then the membrane shell of the reverse osmosis membrane needs to be taken out, and then the membrane shell needs to be opened to replace the reverse osmosis membrane, and then the housing needs to be installed, which makes the process of replacing the reverse osmosis membrane cumbersome and the replacement efficiency is low; the filter also has three filter elements in front of the reverse osmosis membrane, namely PP cotton filter element, granular carbon filter element and compressed activated carbon filter element. These three filter elements are usually installed in a sealed mounting cylinder. After long-term use, a large amount of dirt will accumulate in the sealed mounting cylinder. In order to facilitate cleaning of the sealed mounting cylinder, the sealed mounting cylinder is generally installed on the outside of the filter, but when the sealed mounting cylinder installed on the outside is subjected to external impact, it will directly act on the sealed mounting cylinder, which will damage the filter element inside the sealed mounting cylinder.
