Description

Technical Field

[0001] The utility model belongs to the technical field of smoke sensors, and in particular relates to a novel smoke sensor device. Background Art

[0002] Smoke sensors prevent fires based on the concentration of smoke. Smoke alarms use ionized smoke sensors, which are technologically advanced, stable and reliable sensors that are widely used in various fire alarm systems. Smoke sensors are usually in working order, detecting the smoke concentration in the air at any time. When the smoke in the air reaches a certain concentration, the smoke sensor will sound an alarm to remind people to prevent fires. Since smoke sensors should detect smoke concentrations at any time, they need to be regularly inspected and maintained.

[0003] At present, most of the existing smoke sensors are fixed on the ceiling of the room with bolts. Since they are in a monitoring state for a long time, they need to be regularly inspected and maintained. The traditional bolt installation is troublesome to disassemble and assemble during the maintenance process, which is not conducive to rapid disassembly and maintenance, and reduces the maintenance efficiency. For this reason, we propose a new type of smoke sensing device. Utility Model Content
