Abstract

The present application relates to the technical field of alarms, in particular to a labyrinth structure of a smoke detector and a smoke alarm. The labyrinth structure includes: a base, an upper cover, a light-emitting element and a light-receiving element; the base is arranged on the upper cover, and the side of the upper cover facing the base has a groove, a first curved section and a second curved section, and the first curved section is on one side of the upper cover. The side protrudes, the second curve segment protrudes to the side away from the upper cover, the base has a third curve segment on the side facing the upper cover, the third curve segment protrudes toward the side away from the upper cover, and the third curve segment corresponds to the second curve segment, the first curve segment, the second curve segment and the third curve segment form a smoke particle channel, and a detection chamber is formed between the groove and the base; the side of the base away from the upper cover is provided with a first cavity and the second cavity, both the first cavity and the second cavity communicate with the detection chamber, the light-emitting element is arranged in the first cavity, and the light-receiving element is arranged in the second cavity. The smoke detector maze structure in this application has a low false alarm rate.

Description

technical field [0001] The present application relates to the technical field of alarms, in particular to a labyrinth structure of a smoke detector and a smoke alarm. Background technique [0002] Smoke alarm is a kind of fire alarm equipment that realizes fire early warning by detecting the concentration of smoke particles in the early stage of fire. According to the difference in detection principle, it is mainly divided into two types: photoelectric smoke alarm and ionization smoke alarm. Because of its detection reaction rate is much faster than that of gas sensitive resistor fire alarm equipment, and it has the advantages of simple installation and strong adaptability. It is widely used in important fire prevention places such as homes, factories, office buildings, hospitals, schools, and museums. As the country and families pay more attention to the prevention of fire accidents, the application of smoke alarms is more and more extensive, but the problem of false alarm...
