The bottom side of the sealing block is connected with the outer side of the jacking air bag, the diameter of the sealing block is gradually changed, the sealing block is in a drop shape, a micro air pump is arranged in the mounting groove, and the air inlet end of the micro air pump faces the upper end of the air inlet channel.

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.

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
