Title:
POINT-TYPE ACTIVE SMOKE DETECTOR WITH OR WITHOUT GAS SAMPLING TUBE AND AIR SAMPLING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/116024
Kind Code:
A1
Abstract:
A point-type active smoke detector with or without a gas sampling tube (08) and an air sampling system are disclosed. The detector comprises a main control board (25), a monitoring cavity (23), a sensor (24) composed of a photoemissive tube and a receiving tube, and an air-pumping device. The monitoring cavity (23) is provided with a gas inlet and a gas outlet. The gas inlet on the monitoring cavity (23) is opposite directly to the gas outlet and the gas passing through the monitoring cavity (23) passes a crossing area of two beams between the photoemissive tube and the receiving tube. The point-type active smoke detector, the point-type active smoke detector with a gas sampling tube (08) and the air sampling system can shorten the alarm monitoring time for fire detection and the photoemissive tube and receiving tube can be flexibly arranged; and all these can reduce the cost of the traditional air sampling system.
