Abstract

This utility model belongs to the field of smoke sensor calibration, specifically, it relates to a smoke sensor calibration device. A support assembly includes a support box, an equipment chamber, a calibration chamber, and a first partition. The first partition divides the internal space of the support box into the equipment chamber and the calibration chamber along the height of the support box. Multiple fireproof airbags filled with inert gas are installed on the inner wall of the equipment chamber. A smoke generating assembly is located in the equipment chamber and communicates with the calibration chamber. A filter assembly is located in the equipment chamber and communicates with the calibration chamber. The filter assembly and the smoke generating assembly are spaced apart. A control assembly is connected to the support box and the filter assembly. This solves the problem that the smoke generator in existing smoke sensor calibration devices may cause combustion inside the device during use.
