Abstract
A smoke detector with an anti-insect function includes a substrate, an optical detection module, a top cover, a base and a perforated plate. The substrate has a ring shape region surrounding a central detection region, and a first block structure of the central detection region is protruded from the substrate and higher than an upper surface of the ring shape region. The optical detection module is disposed inside the central detection region. The top cover has a lateral wall. The base is disposed on the substrate and connected to the top cover to cover the optical detection module. The base has a second block structure partly overlapped with the lateral wall to form a guiding channel. The perforated plate is disposed between the lateral wall and the second block structure to prevent an insect from moving into the top cover through the guiding channel.
