PURPOSE:To restrain the supply of oxygen when a power-supply switch is turned off and to restrain a cell reaction by a method wherein an air hole for the air cell is opened and shut in accordance with the ON-state and the OFF-state of the power-supply switch. CONSTITUTION:When a power-supply switch is turned on, the position of a control plate 40 is moved via a slide switch 30 and a coupling lever 41, and air holes 1 are opened. Then, when the power-supply switch is turned off, the position of the control plate 40 is restored via the slide switch 30 and the coupling lever 41, and the air holes 1 are set to a closed state. Thereby, a cell reaction is restrained in a state that the power-supply switch is in an OFF-state, it is possible to prevent a cell from being consumed wastefully, and the life of the cell can be utilized with good efficiency. |
