Patent attributes
An air purifier includes a main frame, a discharging device, a dust collection device and a voltage generator. The discharging device has a discharging portion and is installed in the main frame. The dust collection device has a dust collection portion and is installed in one side of the discharging device. The air purifier can produce ozone, negative ions and static electricity by moving the discharging portion and the dust collection portion and receiving suitable voltage. The voltage generator, the discharging portion, and the dust collection portion accomplish conduction. Production of ozone, negative ions and static electricity occurs according to separation between the discharging portion and dust collection portion, as well as the particular environment of operation, thereby improving air quality.
