烟感报警器的工作原理有哪些？

烟雾是上升运动的，到达天花底下。烟感报警器通过烟发现火灾。在您没有看到火苗或闻到烟味的时候，烟感器已经知道了。它不停工作，一年365天，每天24小时，从不间断。

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.

在报警时，它发出尖啸刺耳的声音，直到烟雾散去。在真实的火灾中它一直工作到被烧毁。

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.

民用住宅的独立式烟感报警器共有两种传感器可供选择：一种是离子传感器，一种是光电传感器。

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

火灾报警器使用方法

Instructions for using fire alarms

离子传感器是通过测量空气中的正负电荷的平衡来工作的。在传感器内部，有一小片放射性物质，这种物质能在感应室内流动的空气中 产生一股微小的电流。在线路板上，有一个电脑芯片用来监测这股电流。

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.

当烟雾粒子进入到感应室后，就会扰乱那里的正负电荷的平衡，同时也会使这股电流发生变化。当烟雾逐渐加重，正负电荷的不平衡性就会加强。当这种平衡性达到一定的限度，喇叭就会响起。

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.

光电传感器是通过一束光和一个光的感应器来测量烟的浓度的。该装置设计的时候，光束是偏离感应器的。当烟雾进入到感应室后，烟雾粒子会将部分光束散射到感应器上。当烟雾的浓度逐渐加重，就会有更多的光束被散射到感应器上。当到达传感器的光束达到一定的程度，蜂鸣器就会响起。

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.
