  • Self-power air refresher system
    Patent number: 10921003
    Abstract: A self-power air refresher system includes an air refresher apparatus and a plant microbial fuel cell (PMFC). The air refresher apparatus includes a fan, a filter located on an air-outlet path of the fan, and an energy storage device connected to the fan. The PMFC is disposed on the air-outlet path and includes soil contained in a container, a plant planted in the soil, and a first and second electrodes. The interaction between roots of the plant and microorganisms near the roots generates electrons, and the electrons are transmitted to the energy storage device through the first and second electrodes installed in the soil so as to enable the energy storage device to supply power to the fan. The air that has passed through the filter enters the soil of the PMFC, and is filtered by the plant and then discharged from the container.
