An automatic alarm device with fire smoke detection function

Abstract

The invention discloses an automatic alarm device with fire smoke detection function, which comprises a fixing device, a gas collecting device, a detection device and a guiding device. The fixing device includes a base and a casing, and one side of the casing is fastened to one side of the base Connection, there are several fixing holes on the base, the gas collecting device is connected to the shell, the detection device is connected to the shell, the guiding device is connected to the shell flexibly, the shell is provided with an air inlet and a mounting groove from bottom to top, The air inlet is connected to the installation groove. The gas collection device includes a micro air pump, a jacking air bag and a sealing block. A sealing block is arranged in the air inlet. There is an air channel on the lifting air bag, the air channel is connected with the air intake channel, the bottom side of the sealing block is connected with the outer side of the lifting air bag, the diameter of the sealing block is gradually changed, the sealing block is in the shape of a drop, and a micro air pump is arranged in the installation groove, and the micro air pump enters The gas end is towards the upper end of the air inlet.

Description

technical field [0001] The invention relates to the technical field of fire smoke detection, in particular to an automatic alarm device with a fire smoke detection function. Background technique [0002] With the continuous development of the domestic urban economy, the population density has also continued to expand. Therefore, the importance of various types of fires has been continuously deepened. efficiency. However, with the continuous application of new materials, various chemical plants and fuel plants continue to emerge, especially some small factories. Fires are likely to cause large economic losses and personal hazards. Most chemical plant fires are prone to produce acid gases, which are highly toxic and corrosive. There are more combustion materials stored in the fuel plant, and the combustion calorific value is relatively large during the fire process. The temperature is high, which is not convenient for fire rescue. In order to target different fires, flame-re...

However, with the continuous application of new materials, various chemical plants and fuel plants continue to emerge, especially some small factories. Fires are likely to cause large economic losses and personal hazards. Most chemical plant fires are prone to produce acid gases, which are highly toxic and corrosive. There are more combustion materials stored in the fuel plant, and the combustion calorific value is relatively large during the fire process. The temperature is high, which is not convenient for fire rescue. In order to target different fires, flame-retardant clothing, heat-insulating clothing, etc. have been produced. Firefighters cause personal harm, which greatly increases the difficulty of fire rescue

In addition, most of the existing fire alarms sense the smoke generated during the fire burning process and alarm through the buzzer, but this type of alarm cannot identify household cooking, people smoking and fire, which is likely to cause monitoring errors and affect the daily life of the family. use
