Description

Technical Field

[0001] The utility model relates to the field of fire protection, in particular to a fire linkage alarm device with a feedback function. Background Art

[0002] Although many types of public places are equipped with fire alarm devices and automatic fire fighting systems, it is difficult for the fire alarm system to detect the fire in its early stages, nor is it easy to be observed by the naked eye. By the time it is discovered, an open flame has often formed, making it difficult to put out the fire in time. The automatic fire alarm system consists of a trigger device, a fire alarm device, and a linkage output device. It can convert physical quantities such as smoke, heat, and flames generated by combustion into electrical signals through fire detectors at the early stages of a fire, and transmit them to the fire alarm controller, and at the same time notify the entire floor to evacuate in the form of sound or light. The controller records the location and time of the fire, so that people can detect the fire in time and take effective measures in time.

[0003] At present, a Chinese patent with authorization announcement number CN215341333U discloses an intelligent fire linkage alarm device, including an equipment box, a smoke sensor and a temperature sensor. The surfaces of the equipment box are respectively fixedly provided with a smoke sensor and a temperature sensor, and the upper surface of the temperature sensor is fixedly provided with a temperature detection probe. In the utility model, by providing a smoke sensor, a temperature sensor and a display, the temperature sensor can be used to detect the temperature of the scene during use. If the temperature value changes greatly, an alarm reminder will be generated. In addition, the smoke sensor can also detect the smoke content in the air on site. If the smoke volume increases rapidly or reaches a certain value, an alarm reminder will be issued, thereby utilizing the effect of double detection to increase the degree of defense and improve the comprehensiveness of the device detection. Moreover, the detected value can be displayed through the display, so that people can understand the changes in the value at any time.

[0004] The above-mentioned prior art solution has the following defects: the device mainly relies on external temperature sensors and smoke sensors to monitor fire conditions, and the range that a single alarm device can monitor is limited and can be blocked by walls. Utility Model Content

[0005] The utility model aims to provide a fire linkage alarm device with a feedback function to solve the problems existing in the above-mentioned prior art.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] A fire linkage alarm device with feedback function, comprising an alarm device body and a wall, wherein the wall is provided with a detection hole, and the alarm device body comprises a shell, a medicine bag, a thermal start device, an electric start device and a feedback device;

[0008] The shell is assembled from a bottom plate and a cover plate, a plurality of through holes are arranged on one side of the cover plate, a groove is arranged on the inner surface of the cover plate, and a medicine bag is arranged in the groove;

[0009] A thermal start device is provided at the bottom of the medicine bag, an electric start device is provided on the left side of the thermal start device, and a feedback device is provided on the right side of the electric start device.

[0014] By adopting the above technical solution, the temperature in multiple areas is monitored by a thermal connector. Once the temperature exceeds the rated upper limit, the thermistor connected to the thermal connector will ignite, and then the medicine bag in the shell will react due to the heat to release the fire extinguishing aerosol, so as to effectively curb the spread of fire. In addition to temperature triggering, the device can also be triggered by the point start connector connected to the smoke alarm. After detecting smoke, the smoke alarm sends back a signal, and the ignition head releases heat to ignite the medicine bag. Whether it is the ignition head or the thermal wire, as long as heat is released, it will affect the feedback device.

The characteristic of aerosol is that it can block the spread of flames once it is dispersed. If the aerosol is released in advance before the fire spreads to this area, it can play a great role in curbing the fire.

[0015] In a further embodiment, a plurality of positioning grooves are provided at the top of the bottom plate, and an ignition head, a hot start device and a feedback device are respectively accommodated in the positioning grooves.

[0016] By adopting the above technical solution, in order to prevent the position of the ignition head, hot start device and feedback device from shifting during the installation process, which would affect the triggering of the entire fire extinguishing alarm device, positioning grooves are first set on the base plate to ensure that these devices can remain in the preset positions.

[0017] In a further embodiment, the ignition head includes a bridge wire and a powder-packed head, the bridge wire is connected to the smoke alarm, and the powder-packed head is sleeved on the bridge wire.

[0018] By adopting the above technical solution, after the smoke alarm is powered on, the bridge wire heats up and ignites the drug pack head, which immediately releases a large amount of heat to trigger the drug pack and generate a fire extinguishing aerosol. This device is simple and reliable, has certain heat insulation properties, can only be triggered by circuit conduction, and is very safe.

[0019] In a further embodiment, a thermistor is disposed inside the feedback device.

[0020] By adopting the above technical solution, when the feedback device is heated, the internal thermistor changes, the circuit is turned on, and the location and time of the fire are reported according to the preset information, which plays an early warning role in the disaster.

[0021] In a further embodiment, a plurality of ventilation slots are evenly arranged on the cover plate.

[0022] By adopting the above technical solution, these ventilation slots are mainly used to facilitate the aerosol to be sprayed out from these preset ventilation slots after the medicine package is subjected to heat reaction, thereby playing a protective role for the surrounding environment.

[0023] In a further embodiment, the alarm device body is electrically connected to the sound and light alarm via an electric wire, and the sound and light alarm is detachably mounted on a wall.

[0024] By adopting the above technical solution, sound and light alarms can be released at the same time as a fire is detected, which can serve as a warning and guidance for people in the venue.

[0025] In summary, the utility model has the following beneficial effects:

[0026] 1. Through the setting of thermal joints and wall detection holes, the temperature transmitted from the other side of the wall can be detected in advance, which can speed up the warning time and release aerosols in advance to prevent the spread of fire;

[0027] 2. Through the setting of the feedback device, the location information and time information of the fire can be quickly uploaded through the Internet of Things device, which can better curb the disaster;

[0028] 3. Through the setting of the smoke alarm, the sensitivity of the alarm device to fire can be increased by adding smoke sensors, thereby improving the detection sensitivity of the alarm device. BRIEF DESCRIPTION OF THE DRAWINGS
