A plasma regeneration assembly 100 according to an embodiment of the present invention will first be described with reference to fig. 1-3. It should be noted that the plasma regeneration assembly 100 according to the embodiment of the present invention can not only filter gases such as air, but also filter some non-conductive liquids, so as to avoid safety risk caused by liquid electrification.
As shown in fig. 1 to 3, a plasma regeneration assembly 100 according to an embodiment of the present invention may include an adsorption filter member 1, and a discharge member 2. The power source may deliver power to the discharge element 2. It is understood that, in the case where the adsorption filter member 1 is used for a long period of time, the adsorption filter member 1 may have residual substances (e.g., filter residues) such as VOCs (i.e., volatile organic compounds) adhered thereto, and the adhered residual substances may reduce the filtering capacity of the adsorption filter member 1.
When the power supply transmits power to the discharge member 2, a voltage difference is generated between the discharge member 2 and the adsorption filter member 1, so that the discharge member 2 can discharge the adsorption filter member 1. The discharge element 2 may have a sufficiently high voltage (e.g., > 1000V) that the air between the discharge element 2 and the adsorption filter member 1 becomes a conductor at the high voltage, so that the discharge element 2 discharges the adsorption filter member 1 through the air.
Thus, when the discharge element 2 discharges to the adsorption filter element 1, the substance such as air in the space between the discharge element 2 and the adsorption filter element 1 can be charged to a plasma state, and plasma can be formed.
