Embodiment Construction
[0029] Below in conjunction with accompanying drawing, the application scheme is further described:
[0030] like Figures 1 to 8 As shown, a light detection type smoke detector based on plastic optical fiber transmission, including
[0031] The upper casing 1; a plurality of mounting holes 10 are provided on it, which are used for fixing the connecting piece to the attachment surface (ceiling), and the connecting piece can be iron nails or screws in specific implementation;
[0032] The smoke collector 2; it comprises a main body 21 formed by nesting a plurality of inverted bucket-shaped components 20, the main body has a first smoke-collecting channel 22 formed by the central funnel of each bucket-shaped component 20, and a The second smoke collecting channel 23 is formed by the gap between the two bucket-shaped components 20 . Some of the second smoke collecting channels 23 are merged into the first smoke collecting channel 22 , and a first smoke collecting channel 22 is f...
