AIRBORNE-SUBSTANCE DETECTION DEVICE AND CARTRIDGE USED IN SAME

摘要

An airborne-substance detection device includes a cartridge and an optical detector. The cartridge includes: an inflow plate having formed therein a micropore that allows inflow of a microparticle-containing gas; a trapping plate disposed opposite the micropore and having the ability to capture the microparticles on a surface facing the micropore; and a main body in which the inflow plate and the trapping plate are installed, and in which a channel is formed that channels the gas to the micropore. The optical detector optically detects the microparticles captured on the trapping plate. The trapping plate is disposed on the outermost side of the cartridge, and is configured from a light transmissive member. The optical detector detects the captured microparticles on the trapping plate from the back side of the trapping plate.

1. A cartridge for airborne-substance detection devices, the cartridge comprising:
an inflow plate having formed therein a micropore that allows inflow of a microparticle-containing gas; a trapping plate disposed opposite the micropore and having the ability to capture the microparticles on a surface facing the micropore; and a main body in which the inflow plate and the trapping plate are installed, and in which a channel is formed that channels the microparticle-containing gas to the micropore, wherein the trapping plate is disposed on the outermost side of the cartridge with the trapping surface facing inward, and is configured from a light transmissive member.
