Abstract

"CâMARA DE DETECãO DE FUMO E DETECTOR DE FUMO FOTOELéTRICO". Uma câmara de detecção de fumo para uso em detector de fumo fotoelétrico é descrita. A câmara de detecção de fumo compreende uma parede lateral com uma fila dupla de asas retangulares que formam um labirinto que se estende geralmente à volta de toda a periferia da câmara de detecção de fumo para entrada e saída das partículas de fumo, um topo e uma base. Um estrutura montada para um diodo fotoemissor é fornecida na parede lateral da câmara de detecção de modo que um raio de luz do diodo fotoemissor é transmitido através da câmara de detecção de fumo. A estrutura se estende e é expandida pela base para fornecer mínima interferência na entrada das partículas de fumo. A base da câmara de detecção de fumo tem uma abertura com o conjunto blindado aberta para a câmara para um fotodiodo detector, a abertura e o conjunto blindado sendo localizado entre a linha de centro da câmara de detecção de fumo e o conjunto montado na parede lateral da câmara. A parede lateral de asas duplas e o espaço do conjunto montado na base fornecendo uma câmara de detecção com propriedades de fumo geralmente uniforme em torno de toda sua periferia.
