The invention discloses a waterproof infrared smoke detector for scattering and throwing. The detector comprises a smoke detector body. An air access is formed in the smoke detector body; and an infrared light-emitting tube and an infrared photosensitive tube are arranged at the two sides of the middle part of the air access symmetrically. An electrode contact A and an electrode contact B are symmetrically disposed at the two sides of the end portion of one end of the air access; an electrode contact C and an electrode contact D are symmetrically disposed at the two sides of the end portion of the other end of the air access; and the electrode contact A, the electrode contact B, the electrode contact C, the electrode contact D, the infrared light-emitting tube and the infrared photosensitive tube are all connected to a control circuit board box through wires. The control circuit board box is fixedly arranged at the center inside the smoke detector body. According to the invention, with the infrared light-emitting tube, the infrared photosensitive tube, and an acceleration inertia sensor, a problem that the traditional smoke sensor is difficult to quickly and accurately monitor the smoke in the near-ground area in harsh environments such as emergency rescue is solved.
Description
technical field [0001] The invention relates to the technical field of smoke sensors, in particular to a waterproof infrared light smoke detector for spreading. Background technique [0002] The smoke detector is a device that can sense the surrounding smoke particles and convert the concentration of the smoke particles into an electrical signal output. It is often used in fire prevention situations. Once it detects smoke exceeding a certain concentration, it will trigger an alarm signal. Commonly used smoke detection methods include ion smoke detection, photoelectric smoke detection and gas-sensitive smoke detection. [0003] Both ion-type and gas-sensitive smoke detectors require the sensor to be exposed to the air, and the sensor and smoke particles interact with each other to sense the smoke concentration, which is not suitable for emergency rescue occasions that require waterproofing, such as indoor fire rescue. , there are situations such as high-pressure water column...
