  • Liquid presence detecting device functioning also as power supply, and air improving device having the same
    Patent number: 9616149
    Abstract: A liquid presence detecting device that has a simple and compact configuration, and which is high in efficiency, and an air improving device including the detecting device. The liquid presence detecting device includes a magnesium-air battery, and an electrical load. When liquid exists in a detection point, the magnesium-air battery operates (generates electricity), and, when liquid does not exist in the detection point, the operation of the magnesium-air battery stops. Therefore, the liquid presence detecting device detects the presence of liquid, and functions also as a power supply. The air improving device includes the liquid presence detecting device functioning also as a power supply, a device body, and an air improver which is detachably attached into the device body.
