CHAMBER CONFIGURATION FOR PARTICLE DETECTOR, THE PARTICLE DETECTOR, SMOKE DETECTOR, AND METHOD FOR FEEDING FLUID FOR DETECTING ZONE OF THE PARTICLE DETECTOR

摘要

PROBLEM TO BE SOLVED: To provide a particle detection apparatus and method which improve the detection, discrimination and analysis of particles, events such as pyrolysis and smouldering and dust.;SOLUTION: An inlet adapted so as to pass a fluid is provided at a detector; a fluid flow is made to diffuse before the fluid flow flows into a particle detection zone, and the diffused fluid flow is fed to the particle detection zone. Here, a chamber configuration is then adapted for the particle detector having the inlet adapted to pass the fluid at a first velocity; and the chamber has a first diffuser which is adapted so as to provide a fluid flow of a second velocity, while diffusing the fluid flow of the first velocity, and which provides the fluid flow of the second velocity to the particle detection zone.;COPYRIGHT: (C)2011,JPO&INPIT
