Patent ID: 7431752

Claim:
An air purifier, comprising: an outer case having top portion, a bottom portion, an air purifying cavity defining between said top and said bottom portion, and a peripheral opening communicating with said air purifying cavity; an ionizer module, which comprises: a power unit supported at said outer casing, wherein the power unit comprises an electrode terminal; and an ionizing electrode unit supported within said air purifying cavity to electrically couple with said electrode terminal for ionizing ambient air in a vicinity of said ionizing electrode unit to generate an airflow and ozone within said air purifying cavity to exit at said peripheral opening of said outer casing; and an ozone reduction module electrically connecting to said power unit for generating heat within said air purifying cavity, wherein when a temperature within said air purifying cavity reaches a preset temperature, a level of ozone generated by said ionizing electrode unit is substantially minimized and controlled for preventing excess generation of ozone.
