Abstract
A smoke detection device includes a housing, a smoke collector, an optical detector and a cover plate. The housing has a piercing hole. The smoker collector has a smoke hole, and position of the smoke hole is close to position of the piercing hole. The optical detector is disposed inside the smoke collector and adapted to detect gaseous concentration inside the smoke collector. The cover plate is disposed between the housing and the smoke collector, and used to set a channel from the piercing hole to the smoke hole, so that gaseous matter flows from outside the smoke detection device into the smoke collector through the piercing hole and the smoke hole.
