Description

Technical Field

[0001] This utility model relates to the field of filter technology, specifically to a pre-filter. Background Technology

[0002] With the improvement of people's living standards and the enhancement of their health awareness, more and more families are paying attention to drinking water health, and pre-filters have become the main water filtration device in many households. Pre-filters are usually installed at the beginning of the household tap water pipes to filter tap water in advance, facilitating subsequent water treatment. As the first line of defense for household water use, pre-filters can intercept large particles such as sediment and rust at the source, ensuring clean drinking water and protecting the safety of end-use water equipment. Especially for water purifiers, the large particles filtered out in advance reduce the workload of the filter cartridges and reduce cartridge wear. However, existing pre-filters are inconvenient to install and remove, and filter cartridge replacement is also inconvenient, which is detrimental to installation and use, resulting in a poor user experience. Therefore, to avoid the shortcomings of existing technology, it is necessary to improve it. Utility Model Content
