Patent ID: 7244289

Claim:
An air purifier, comprising: an outer casing having a top portion, a bottom portion having an electrode opening, an air purifying cavity defining between said top and bottom portions, and a peripheral opening communicating with said air purifying cavity; and an ionizer module, which comprises: a power unit supported within said top portion of said outer casing, wherein said power unit comprises an electrode terminal extended downwardly; a plurality of electrode wires longitudinally extended within said air purifying cavity to electrically connect to said power unit; and an ionizing electrode unit, which is detachably mounted to said outer casing, comprising a plurality of detachable electrode blades spacedly and upwardly slid into said air purifying cavity through said electrode opening of said bottom portion of said outer casing for minimizing a weight of said ionizing electrode unit applying at said electrode terminal, wherein said electrode wires are supported within said air purifying cavity at a position aligning with said detachable electrode blades, wherein each of said detachable electrode blades has a top terminal end arranged to electrically contact with said electrode terminal of said power unit for ionizing an ambient air in a vicinity of said detachable electrode blades, such that said ionizing electrode unit is adapted for generating an optimal level of ozone emission to said ambient air to form an air flow passing out of said outer casing through said peripheral opening.
