Cleaning type fire hazard smoke detector

Abstract

The invention discloses a cleaning type fire hazard smoke detector, comprising a pedestal; a cover is arranged on the pedestal; the cover is internally provided with a smoke detector body; the smoke detector body is provided with smoke detection probes; the smoke detection body is provided with an elevation guiding shaft by passing through; a rotary sleeve sleeves the elevation guiding shaft; the lower ends of the elevation guiding shaft and the rotary sleeve are provided with a limiting stop mechanism; the upper end of the elevation guiding shaft is connected to a driving connection rod; a press handle is connected to the driving connection rod; a press returning mechanism is arranged between the press handle and the cover; the upper end of the rotary sleeve is connected to a rotary support; the lower part of the rotary support is provided with a cleaning brush; a rotary traction mechanism is arranged between the elevation guiding shaft and the rotary sleeve; and the rotary returning mechanism is arranged on the outside of the rotary sleeve. The cleaning type fire hazard smoke detector can accurately detect the condition of the fire hazard, provides convenience to cleaning inside pollutants and foreign matters, improves the sensing accuracy and guarantees the safety of people and property.

Description

technical field [0001] The invention relates to a power electronic device, in particular to a fire detector. Background technique [0002] Fire detectors are used to determine the possibility of fire, and are commonly used monitoring equipment in factories, residential buildings and office buildings, so as to avoid personal and property safety problems caused by fire. Most of the structures of the existing fire detectors are holes in the closed casing for hot air or smoke to enter the sensing area, but the structures of the existing fire detectors have the following disadvantages: dust, dust, Smoke particles will enter the sensing area from the opening on the casing, and if used for a long time, it will cause insensitivity of the device and affect the detection effect. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a clean fire smoke detector that can accurately detect fire hazards, facilitate cleaning of inter...
