Abstract: The present application discloses a magnet-driven fire damper for an oxygenerator, which includes a rear valve housing, a front valve housing and a fusible valve core, and further includes a static magnet and a moving magnet, wherein the static magnet is fixedly mounted at a front end of a middle hole of the rear valve housing and does not affect the passage of oxygen, and the moving magnet is fixedly connected to a rear end of the fusible valve core and is provided opposite to the static magnet; the opposing faces of the static magnet and the moving magnet are of the same polarity. In the present application, a magnet-driven fire damper for an oxygenerator, mutually exclusive magnets are used as a driving unit of a fusible valve core, avoiding the influence of water vapor, and being sensitive and reliable in operation.

Abstract: A gas detecting system includes a detector having a housing, a sensor module, a controller, energy storage, and a photoelectric conversion component. The photoelectric conversion component may be mounted in or on the housing to provide electrical power to the energy storage while the energy storage powers the detector. Accordingly, the photoelectric conversion component can extend working time of the detector beyond the normal capabilities of the energy storage alone. The gas detecting system may further include a base station that provides light for charging or operation of the detector and that communicates with the detector for programming of the detector and processing of measurement data.

Abstract: Embodiments of the disclosure relate to systems and methods for isolating a base station beacon and gas reading transmission channel(s) based on a single radio wireless gas detection system. A gas detector may communicate on a first channel (e.g. a beacon channel) constantly listening to the base station beacon information. At a pre-defined interval (e.g. every 60 seconds), the gas detector radio may switch to a second channel (e.g. a data channel) to transmit gas reading data as well as the base station information to a central server. Software on the server may complete a triangulation algorithm to determine the location of the gas detector, using information obtained by the detector from the beacons.
