Description

Technical Field

[0001] The utility model relates to the technical field of smoke alarms, in particular to a smoke alarm installation structure. Background Art

[0002] Smoke alarms achieve fire prevention by monitoring 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, and their performance is far superior to that of gas-sensitive resistor fire alarms. It has a radioactive source, americium 241, in the inner and outer ionization chambers. The positive and negative ions generated by ionization move toward the positive and negative electrodes respectively under the action of the electric field. Under normal circumstances, the current and voltage of the inner and outer ionization chambers are stable. Once smoke escapes from the outer ionization chamber, the normal movement of charged particles is disturbed, and the current and voltage will change, destroying the balance between the inner and outer ionization chambers. Then the wireless transmitter sends out a wireless alarm signal to notify the remote receiving host and transmit the alarm information.

[0003] Existing smoke alarms are usually installed directly on the indoor ceiling. After the base of the smoke alarm is penetrated by bolts or screws, the smoke alarm body and the smoke alarm are usually connected by a snap-on connection. During installation, personnel need to align the snap-on connection. Since the smoke alarm is installed on the indoor ceiling, it is inconvenient for personnel to raise their heads to align during the snap-on connection, resulting in reduced efficiency during the later maintenance and disassembly of the smoke alarm, thus affecting the later maintenance efficiency. To this end, we propose a smoke alarm installation structure to facilitate the plug-in connection between the smoke alarm body and the smoke alarm base, thereby improving the installation efficiency of the smoke alarm and increasing the maintenance efficiency.
