煙感報警器的工作原理有哪些？

煙霧是上升運動的，到達天花底下。煙感報警器通過煙發現火災。在您沒有看到火苗或聞到煙味的時候，煙感器已經知道了。它不停工作，一年365天，每天24小時，從不間斷。

Smoke rises and reaches below the ceiling. The smoke detector detects a fire through smoke. When you haven't seen any flames or smelled smoke, the smoke detector already knows. It works non-stop, 365 days a year, 24 hours a day, without interruption.

在報警時，它發出尖嘯刺耳的聲音，直到煙霧散去。在真實的火災中它一直工作到被燒毀。

When the alarm is triggered, it emits a sharp and piercing sound until the smoke dissipates. In a real fire, it worked until it was burned down.

民用住宅的獨立式煙感報警器共有兩種傳感器可供選擇：一種是離子傳感器，一種是光電傳感器。

There are two types of sensors available for independent smoke detectors in residential buildings: ion sensors and photoelectric sensors.

Instructions for using fire alarms

離子傳感器是通過測量空氣中的正負電荷的平衡來工作的。在傳感器內部，有一小片放射性物質，這種物質能在感應室內流動的空氣中 產生一股微小的電流。在線路板上，有一個電腦芯片用來監測這股電流。

Ion sensors work by measuring the balance of positive and negative charges in the air. Inside the sensor, there is a small piece of radioactive material that can generate a small current in the air flowing inside the sensing chamber. On the circuit board, there is a computer chip used to monitor this current.

當煙霧粒子進入到感應室后，就會擾亂那里的正負電荷的平衡，同時也會使這股電流發生變化。當煙霧逐漸加重，正負電荷的不平衡性就會加強。當這種平衡性達到一定的限度，喇叭就會響起。

When smoke particles enter the sensing chamber, they will disrupt the balance of positive and negative charges there, and also cause a change in this current. As the smoke gradually intensifies, the imbalance of positive and negative charges will strengthen. When this balance reaches a certain limit, the horn will sound.

光電傳感器是通過一束光和一個光的感應器來測量煙的濃度的。該裝置設計的時候，光束是偏離感應器的。當煙霧進入到感應室后，煙霧粒子會將部分光束散射到感應器上。當煙霧的濃度逐漸加重，就會有更多的光束被散射到感應器上。當到達傳感器的光束達到一定的程度，蜂鳴器就會響起。

Photoelectric sensors measure the concentration of smoke through a beam of light and a sensor of light. When designing this device, the beam deviated from the sensor. When smoke enters the sensing chamber, smoke particles will scatter some of the light beam onto the sensor. As the concentration of smoke gradually increases, more light beams will be scattered onto the sensors. When the beam of light reaching the sensor reaches a certain level, the buzzer will sound.
