Title:
PLASMA GENERATION DEVICE AND AIR PURIFIER
Document Type and Number:
WIPO Patent Application WO/2023/207155
Kind Code:
A1
Abstract:
A plasma generation device (100) and an air purifier. The plasma generation device (100) comprises: a spiral electrode (1) comprising an inner electrode (11), an insulating layer (13) wrapping the inner electrode (11), and a carbon fiber electrode (12) spirally wound outside the insulating layer (13), wherein the inner electrode (11) is connected to an alternating current power supply, and the carbon fiber electrode (12) is grounded; and a direct-current electrode (2) provided on one side of the spiral electrode (1), wherein the distance between the direct-current electrode (2) and the spiral electrode (1) is L, L≤5 mm, the direct-current electrode (2) is connected to a direct-current power supply, and a through hole (21) is formed in the direct-current electrode (2). The plasma generation device (100) can generate glow discharge between the spiral electrode (1) and the direct-current electrode (2), such that glow discharge on the plane is converted into glow discharge in space, and the purification range of the plasma generation device (100) can be effectively expanded without increasing the number of electrodes in the plasma generation device (100). Moreover, the plasma generation device (100) also has the dust collection effect, and has a good capability of removing particulate matters.
