Description

[0001] Technical field [0002] The invention relates to a smoke detection device, in particular to a portable smoke detection device. Background technique [0003] The smoke detector realizes fire prevention by monitoring the concentration of smoke. The ion smoke sensor is used inside the smoke detector. The ion smoke sensor is a kind of advanced technology, stable and reliable sensor, which is widely used in various fire alarms. In the system, the performance is far superior to the fire alarm of the gas sensitive resistance type. [0004] It has the radioactive source americium inside the inner and outer ion chambers 241 , 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 there is smoke fleeing outside the ionization chamber. Interfering with the normal...
