Therefore, when the aeration disc is not provided, the sterilizing capability of the sterilizing water prepared by the sterilizing water preparation device is weaker; the aeration module of the catalyst is added in the plasma device, so that the plasma device has better sterilization capability under the same discharge condition, and even if the discharge voltage is reduced, the plasma device can achieve the sterilization capability better than that under high voltage, and the energy consumption is saved.
It should be noted that "inward" is a direction toward the center of the accommodating space, and "outward" is a direction away from the center of the accommodating space.
