Capacitor type smoke detector

Abstract

The invention relates to a smoke fire detector, in particular to a capacitive smoke fire detector, and solves the problem that the existing fire detector has complex application background and is effected by different interference sources; the invention comprises a shell and a capacitor, wherein, the capacitor comprises 3 to 20 layers of capacitance plates and two electrode rods; the capacitance plate has round plate shape with the diameter of 30 to 150mm, wherein, two sides of an insulating plate are respectively provided with an upper layer of capacitance pole and a lower layer of capacitance plate; the upper layer of capacitance poles of adjacent capacitance plates are connected in parallel by an upper layer of parallel leads; the lower layer of capacitance plates of adjacent capacitance plates are connected in parallel by a lower layer of parallel leads; the capacitance plates are fixed on the two electrode rods; the distance of the adjacent capacitance plates is 2 to 10mm; the capacitor is arranged at the lower part of the inner of the shell; an anti-insect net is positioned at the lower part of the shell; the invention is a capacitive fire detector based on a new concept, which has simple form, complete function, wide environment background adaptive capacity and realizing capacity of improving the effective function in the condition of complex environment.

Description

technical field [0001] The invention relates to fire detection technology, which belongs to fire science and can be applied to automatic fire detection in typical places, that is, a smoke-sensing fire detector. Background technique [0002] Fire is one of the most serious disasters to human society. People have been fighting against fire since ancient times. But until the 1960s, with the development of electronic technology, people gradually realized the automatic detection of fire. The same drastic change as the development speed of human society is that the types and hazards of fires are becoming more and more serious. People have become more and more rich in various technologies, and more and more technical means have been applied to the field of automatic fire detection. At present, people have been able to The purpose of automatic detection of fires in most places is realized, but the problem of false alarms of fire detectors still deeply troubles people. At present, ...
