The operation principle of water purifier is as follows:

Water inlet change-over switch (3) is fixed on the tap (1) with screw (51), change-over switch (3) has 2 positions, running water discharges water or purifies waste water and discharges water, when need are used running water, promote push button, make steel ball block the inlet opening that change-over switch (3) communicates with water inlet pipe (2), just can directly use running water, when the needs use is purified waste water, push button is shifted onto the position of purifying waste water, at this moment steel ball again then block another inlet opening, and water purification water inlet pipe (2) is connected, water enters prefix switch (15) left end by water inlet pipe (2), at this moment prefix switch (15) still is in closed condition, as long as handle (52) with prefix switch under the hand (15), so water is just by the hole (23) of base (13), enter in the cover cap (4) with again by groove (17), horizontal stepped hole (24) flows out, and enters the 2nd base (25) again via joint (10), under the pressure effect of water, flow through around the smart filter filter core outer wall, flow into inwall, the endoporus by base (25) flows out base (25) again, last water is through the double filtration effect of coarse filtration and smart filter, flowed out by outlet pipe, when the handle that unclamps prefix switch (15) (45), water is cut off.Its micropore size of filter core (5) that is used for coarse filtration is about 4 μ m, larger particles in can filtering water, colloid, iron rust, mud, the suspension that active carbon in the filter core is contained in can adsorbed water, bacterium and peculiar smell are used for the smart filter core of filtering (40), and its micropore size is less than 0.2 μ m, can be further bacterium in the water, coliform filters.

Compared with prior art, household water filter has following advantages:

1. coarse filtration filter core and smart filter filter core two are housed partly, can the filtering larger particles, micelle, iron rust and bacterium, good purification.

2. change-over switch is housed, can selects running water or purify waste water.

3. simple in structure, adult is low, is easy to promote the use of.

4. be easy to periodic cleaning, guarantee the filtering effect.
