[0029] Specifically,

[0030] Regarding the multi-connection form filter assembly 5,

[0031] The multi-connection type filter assembly 5 includes two sets of quartz sand filter, activated carbon filter and precision filter, one set of which is the first quartz sand filter 19, the first activated carbon filter 20 and the first precision filter 21, and the other set is the second quartz sand filter 1901, the second activated carbon filter 2001 and the second precision filter 2101, the first quartz sand filter 19, the first activated carbon filter 20 and the first precision filter 21 are connected in series through a single pipe, and the second quartz sand filter 1901, the second activated carbon filter 2001 and the second precision filter 2101 are connected in series through multiple pipes. The quartz sand filter, activated carbon filter and precision filter are used as filters to realize water upgrading.

[0032] First of all, the combination of quartz sand filter, activated carbon filter and precision filter, this combination is to filter impurities in raw water, the effect is very good, and has a certain use basis;
