Air purification device

An air purification device comprising:

• a body case including an intake port and an outlet;
• an electrolytic tank disposed in the body case and storing water including sodium chloride;
• an electrolysis unit that electrolyzes the water in the electrolytic tank to generate water including active oxygen species;
• a sterilization tank to which the water including the active oxygen species of the electrolytic tank is supplied;
• a gas-liquid contact portion including a lower end immersed in the water including the active oxygen species of the sterilization tank;
• an air blower that blows air sucked from the intake port to the outlet via the gas-liquid contact portion;
• an opening located on a bottom surface of the electrolytic tank;
• a valve member that covers the opening;
• and
• a movement mechanism that moves the valve member,
• wherein
• the sterilization tank is disposed below the opening,
• by the movement mechanism, when the valve member is separated from an opening edge of the opening, the opening is opened, and the water including the active oxygen species in the electrolytic tank is supplied to the sterilization tank, and when the valve member hits the opening edge of the opening, the opening is closed, and the supply of the water including the active oxygen species in the electrolytic tank to the sterilization tank is stopped.
