Description

Technical Field

[0001] The utility model relates to the technical field of disaster early warning, and more specifically, to an Internet of Things fire alarm device. Background Art

[0002] With the rapid advancement of communication technology, the Internet of Things has been rapidly promoted and used. By using smart terminal devices such as mobile phones, laptops, wearable devices, etc. to connect to automatic fire alarm devices, real-time video surveillance information in the home can be obtained, which greatly improves the efficiency of fire fighting and avoids false fire reports to the fire center.

[0003] After long-term use, the electronic components inside the existing fire warning device may age and be damaged, causing the device to malfunction. In order to ensure the normal use of the device, it is necessary to repair or replace it in time. However, most of the existing fire warning devices are fixed on the wall by screws, which makes it inconvenient for staff to disassemble them. After disassembly, holes will remain in the wall, affecting the wall structure.

[0004] In order to solve the above problems, the utility model patent with publication number CN212782238U discloses an Internet of Things fire evacuation alarm device, which is affixed to the wall by external fixing glue. The shell can be stably mounted on the mounting plate by the clamping action between the L-shaped clamping rod and the clamping slot, and the L-shaped clamping rod can be moved out of the clamping slot through the sliding opening by rotating the shell to a certain angle, so that the shell can be quickly disassembled, and the electronic components in the device can be maintained or replaced.

[0005] However, when the alarm device is actually used, when it is fixed to a relatively smooth wall surface, the fixing glue may fall off after a period of use, leaving stains on the wall surface that are difficult to clean. At the same time, a lot of dust will accumulate in the dust cover after a period of use, affecting the accuracy of the alarm device. Utility Model Content
