The invention relates to the technical field of smoke alarms, and proposes a smoke detector that is waterproof and foggy, including a base, a ventilating grille, and a light emitter, a barrier plate, a light receiver, and a barrier plate arranged on one side of the base. It is arranged on one side of the light path of the light emitter, one side of the blocking plate is a shielding area, the light receiver is located in the shielding area, the air-permeable grille is arranged on the other side of the base, and it also includes a dehumidification mechanism arranged on the base and a The seal on the air-permeable grille, the dehumidification mechanism includes a sealed chamber, a guide and a dehumidifier, the dehumidifier is set on the guide, the dehumidifier is located in the sealed chamber, the guide is moved and set on the base, and the guide can drive the dehumidifier to enter Or leave the airtight compartment. Through the above technical solution, the problem of false alarms in smoke detectors in the prior art due to water mist interference is solved.
Description
technical field [0001] The invention relates to the technical field of smoke alarms, in particular to a smoke detector that is waterproof and fog-proof. Background technique [0002] Photoelectric smoke detectors, with smoke as the main detection object, are suitable for places where there is a smoldering stage in the initial stage of a fire. Among them, the photosensitive element and the optical darkroom are the main components of the smoke detector. The photosensitive element is composed of a light emitter and a light receiver. Under normal circumstances, the light emitted by the light emitter will not be received by the light receiver; When the smoke enters the optical darkroom, the smoke particles have a scattering effect on the light, so that part of the light emitted by the light emitter is scattered to the light receiver, and the receiving tube receives the optical signal and transmits it to the control module, thereby triggering an alarm. [0003] In the prior art, ...
