Cartridge for airborne substance sensing device, and airborne substance sensing device

A cartridge for an airborne substance sensing device, comprising:

• an introduction plate on which at least one micropore through which a gas containing an airborne substance can pass is formed;
• a transparent collection plate disposed so as to face the introduction plate and capable of collecting the airborne substance due to collision of the airborne substance caused by collision of the gas which has passed through the micropore;
• a main body in which the introduction plate and the collection plate are disposed in parallel and a flow path for guiding the gas containing the airborne substance to the micropore is formed;
• and
• an opaque mask covering the collection plate and provided with at least one opening window through which light can pass at a position corresponding to a collection area on the collection plate in which the airborne substance is collected by collision;
• wherein
• the opening window of the mask is disposed so as to overlap with the area in which the airborne substance is captured and so as to have an area the same as or larger than the area in which the airborne substance is captured;
• the number of the at least one opening window of the mask is equal to that of the at least one micropore;
• the cartridge is formed such that a gas containing an airborne substance flows along a surface of the collection plate from the center to the outer periphery;
• the opening window of the mask is formed so as to deviate to the outer periphery of the collection plate with respect to a position of the corresponding micropore with a predetermined amount;
• and
• the area of the opening window of the mask is smaller than four times the area of the micropore.

• an opaque mask covering the collection plate and provided with at least one opening window through which light can pass at a position corresponding to a collection area on the collection plate in which the airborne substance is collected by collision;
• a single or a plurality of containers for holding a liquid;
• a flow path for coupling a space between the introduction plate and the collection plate to the containers;
• a waste container for storing the liquid which has flown between the introduction plate and the collection plate;
• a flow path for coupling the space between the introduction plate and the collection plate to the waste container;
• a pump for generating a flow of the air in a direction from the introduction plate to the collection plate;
• and
• an optical sensor for optically sensing the airborne substance captured on the collection plate;
• wherein
• the airborne substance sensing device makes the liquid in the container flow to the waste container though a space between the introduction plate and the collection plate with the pump.
