Description

Technical Field

[0001] The utility model belongs to the technical field of security management, and specifically relates to an intelligent smoke alarm device. Background Art

[0002] A smoke alarm is a device that uses an alarm to attract the attention of operators and take measures. The smoke alarm can detect large amounts of smoke generated during a fire and send out an alarm signal in a timely manner. It can be widely used for fire safety monitoring in places such as hotels, stores, Internet cafes, coffee shops, and residences. The smoke alarm prevents fires by detecting the concentration of smoke, but the smoke alarm is usually fixed to the wall. After the smoke alarm is fixed to the wall for a long time, a lot of dust will accumulate on the outside of the smoke alarm. Especially in dusty places such as construction sites, the dust will affect the sensitivity and accuracy of the smoke alarm, so the smoke alarm needs to be cleaned regularly. Existing smoke alarms are connected to the wall with bolts, which makes it difficult to disassemble the smoke alarm for cleaning and maintenance.

[0003] The utility model patent with authorization announcement number CN220271986U discloses a fire safety alarm device, which includes an alarm body and a rotating disk. A circular base is fixedly connected to one end of the alarm body, and the rotating disk is arranged at an end of the alarm body away from the base, and a vertical rod coaxial with the base is fixedly connected to the rotating disk. The vertical rod passes through the alarm body and is threadedly connected to the base. The rotating disk of the fire safety alarm device is threadedly connected to the base, and the rotating disk and the alarm body are both fixed by threading the vertical rod of the rotating disk to the base. The threaded connection is prone to slippage, resulting in a loose connection between the vertical rod and the base. At the same time, the weight of the rotating disk and the alarm body is borne by the connection point between the vertical rod and the base, which can easily cause the rotating disk, the alarm body and the base to be loosely connected and fall off.
