Acousto-optic integrated fire alarm

Abstract

The invention relates to the technical field of alarms, in particular to an acousto-optic integrated fire alarm which comprises a base, a device plate, an alarm lamp body and a buzzer body, a liquid storage tank is formed in the device plate and filled with cleaning liquid, a hollow rotating shaft is rotatably mounted in the liquid storage tank, and the hollow rotating shaft is rotatably mounted in the device plate. A round opening communicating with the interior of the hollow rotating shaft is formed in the position, at the bottom of the liquid storage tank, of the middle of the hollow rotating shaft, and the lower end of the hollow rotating shaft penetrates through the device plate and is fixedly provided with an arc-shaped rod. A hollow rotating shaft can be driven to rotate quickly after a fire disaster occurs, then the hollow rotating shaft can drive an arc-shaped rod and a cleaning strip to rotate, accumulated dust outside the warning lamp body is brushed, and meanwhile the cleaning efficiency of the cleaning strip on the accumulated dust outside the warning lamp body can be improved through cleaning liquid; and the situation that the warning effect is affected due to the fact that light emitted by the warning lamp is blocked by dust is avoided.

Description

technical field [0001] The invention relates to the technical field of alarms, in particular to an acousto-optic integrated fire alarm. Background technique [0002] Fire alarm is one of the most important means to prevent fire. Its function is to generate an alarm when a large amount of smoke causes a fire. Fire alarm is an alarm device used to remind the surrounding people of a fire incident. It is most often used in fire alarms. Most of the existing fire alarms use bells and sounds as alarms. In order to achieve a better alarm effect, the existing alarms also often use sound and light integrated equipment. In addition to sounding, it can also sound a light alarm. [0003] Fire alarms are often installed at high places in evacuation passages, and generate warning lights and sirens when a fire occurs. Due to their installation location, it is difficult for ordinary people to reach the position of the alarm, and due to the contingency of fire, the fire alarm will There is ...

Problems solved by technology

[0003] Fire alarms are often installed at high places in evacuation passages, and generate warning lights and sirens when a fire occurs. Due to its installation location, it is difficult for ordinary people to touch the position of the alarms, and due to the sporadic nature of fires, fire alarms will There is a long-term idle situation, which makes the dust in the outside air easy to adhere to the outside of the warning light, and it is not convenient for ordinary people to clean its appearance. In the event of a fire, the dust attached to the outside of the warning light will emit light. The light is blocked, which affects its warning effect, thus posing a great safety hazard
