Smoke-light composite fire detector

The smoke-light composite fire detector provided by the utility model comprises the base body, the surface of the base body is provided with the plurality of guide type flues, the interior of the base body is provided with the optical sensor and the smoke detector, and the diameters of the guide type flues are gradually reduced, so that smoke is accelerated to flow out by adopting a trumpet-shaped structure, and the smoke flow resistance is reduced; the sensitivity and the response speed of the detector are improved, the optical sensor and the smoke detector are adopted to detect a fire, the phenomenon of fire report failure is avoided, fire spreading and expansion are effectively prevented, and casualties or property loss are avoided. 本实用新型提供的一种烟光复合火灾探测器，包括基体，其表面设置有多个引导式烟道，内部设置光学传感器和烟雾探测器，由于引导式烟道的直径逐渐减小，采用喇叭形结构使烟气加速流出，减小了烟气流动阻力，提高了探测器的灵敏度和响应速度，同时采用光学传感器和烟雾探测器进行探测火灾，避免出现火灾漏报的现象，有效地防止火势的蔓延和扩大，避免发生人员伤亡或财产损失。
