Description

Technical Field

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

[0002] A smoke alarm is a device used to detect smoke in a fire. It is commonly used for fire prevention in homes, schools, factories and other places. The alarm is mainly composed of two parts: a sensor and an alarm. The sensor is mainly responsible for detecting smoke, while the alarm sounds an alarm when it senses smoke. The working principle is that when smoke enters the sensor, the particles in the smoke will adhere to the inside of the sensor, changing the impedance of the sensor, thereby changing the current, and then changing the output voltage. When this voltage reaches a certain value, it will trigger the alarm to sound an alarm. In addition, smoke alarms also have the advantages of high sensitivity, strong reliability, and low power consumption. However, due to environmental factors and long-term use, the sensitivity may decrease or false alarms may occur, so regular inspection and maintenance are required. In general, smoke alarms are an effective fire prevention tool that can detect fires in time and remind people to take action, thereby reducing losses caused by fires.
