Description

Technical Field

[0001] The present application relates to the technical field of fire sound and light alarms, and in particular to a fire sound and light alarm that is easy to adjust. Background Art

[0002] The basic structure of the fire sound and light alarm mainly includes three parts: sensor, signal processing unit and alarm output device. The sensor is responsible for detecting the smoke, temperature and other signals generated by the fire, and the signal processing unit processes and judges the signals collected by the sensor. Once it is determined that a fire has occurred, it will trigger the alarm output device to send out sound and light alarm signals;

[0003] The sensor of the fire sound and light alarm usually adopts a smoke sensor or a temperature sensor. The smoke sensor uses optical principles to detect smoke particles in the air, and once the smoke concentration exceeds the set threshold, it will output an electrical signal. The temperature sensor determines whether a fire has occurred by detecting changes in the ambient temperature. When the temperature rises to a certain level, it will also output an electrical signal; after the signal processing unit receives the electrical signal output by the sensor, it will perform a series of processing and judgment. First, it will amplify and filter the signal to eliminate interference and noise. Then, it will compare the processed signal with the preset fire threshold. If the signal value exceeds the threshold, it is considered that a fire has occurred. At this time, the signal processing unit will send an instruction to the alarm output device to trigger the alarm; after receiving the instruction from the signal processing unit, the alarm output device will immediately start the sound and light alarm. Among them, the sound alarm usually uses a high-decibel buzzer or alarm sound to attract people's attention. The light alarm is carried out by flashing LED lights or strong light projection, so that it can be clearly seen in smoke or dark environments;

[0004] In the utility model with Chinese patent authorization announcement number CN215636275U, a fire sound and light alarm that is easy to adjust and move is disclosed in the specification, which relates to the technical field of fire sound and light alarm. In view of the existing problems, the following scheme is proposed, including a bottom plate with movable wheels installed at the four corners of the bottom outer wall, a support mechanism and a pulley mechanism, a support plate is welded to the top outer wall of the bottom plate, and a slide groove is opened on the outer wall of one side of the support plate, a screw rod is arranged in the slide groove, and the bottom end of the screw rod is connected to the inner wall of the bottom of the slide groove through a bearing, and the top end of the screw rod is connected to the outer wall of the support plate through a bearing, and a servo motor is installed on the outer wall of the other side of the support plate. The utility model is convenient for transferring the body of the fire sound and light alarm. After transferring to the desired position, the threaded rod can be rotated to drive the pressure plate to move downward and press the ground, which plays a good supporting role for the whole device, and the position height of the body of the fire sound and light alarm can be adjusted to facilitate the adaptation to material stacking sites of different sizes.

[0005] This document uses a servo motor and a screw rod to adjust the height of the mounting plate and the fire sound and light alarm body. However, the alarm will only be sounded when a large amount of smoke generated by a fire enters the fire sound and light alarm body. The alarm and prompt cannot be sounded when the fire is very small, resulting in a lot of rescue time being missed, a large amount of material burning, and property loss. Utility Model Content
