In the latter mode, because plasma needs a power plant to maintain the plasma, after the plasma is emitted, the duration is very short, and the amount of active ions can be greatly reduced in the emitting process, so that in order to improve the concentration of the active ions when the plasma contacts the skin, the ionization structure is usually arranged to be closer to a port, and when a circuit fault occurs, a large potential safety hazard exists when the voltage is too high.

Secondly, for the continuous plasma flow, when the continuous plasma flow is blown to the skin, the action time of the continuous plasma flow with the skin is blown away by the subsequent airflow only at the moment of contacting the skin, namely, the action time with the skin is too short, the action effect is reduced, and the contact area of direct ionization is smaller, so that the disinfection and sterilization effects are also influenced.
