The fan 102 can suck air from the air inlet 34, the air forms purified air after passing through the water curtain filter element 16, and the purified air is discharged from the air outlet 36 after passing through the fluid passage 96 and the vent hole 106 in sequence, and is circulated, so that the indoor air can be purified.

The product of the invention is an excellent air purification product pioneer, which not only has the characteristics of killing various harmful microorganisms and eliminating toxic substances, but also has the advantages of safety, high efficiency, broad spectrum, convenient storage, convenient use and the like; effectively and thoroughly solves the quality problem of indoor secondary polluted air.

In summary, in one embodiment of the present application, the air purifier 10 includes a water storage tank 12, a body assembly 14, and a water curtain filter element 16.
