Description

Technical Field

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

[0002] Fire smoke sensor alarm, also known as fire smoke alarm, smoke sensor, smoke sensor, etc., it achieves fire prevention by monitoring the concentration of smoke. Generally, the independent physical product is battery-powered, or the AC power supply battery is used as a backup power. It can emit sound and light indication when the alarm is triggered. The smoke alarm achieves fire prevention by monitoring the concentration of smoke. It uses an ionization smoke sensor inside. It is a technologically advanced, stable and reliable sensor that is widely used in various fire alarm systems. It has a radioactive source americium 241 in the inner and outer gas collection chambers. The positive and negative ions generated by ionization move to 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 into the gas collection chamber, interference If the normal movement of charged particles is affected, the current and voltage will change, destroying the balance between the inner and outer ionization chambers. The generated electrical signal is received by the single-chip microcomputer, and the single-chip microcomputer controls the speaker and warning light to work, issue an alarm message, and complete the alarm effect. Usually, the fire smoke sensor alarm is powered by a dry battery, which needs to be replaced regularly. When replacing the dry battery, the alarm needs to be removed from the mounting base and then replaced. The existing alarm is mostly fixed by bolts or threads, which has some problems. The fire smoke sensor alarm is mostly installed on the ceiling of the room, which is relatively high.
