Description

HELMET TYPE FIREFIGHTING MASK COOLING PROTECTION SYSTEM AND METHOD
BASED ON THERMOELECTRIC DEVICE
Technical field
The invention relates to the technical field of fire safety protection, in particular to a helmet type fire mask cooling pro- tection system based on a thermoelectric device and a protection method.
Background Technology
Fire is one of the disasters that seriously threaten the sur- vival and development of human beings. The occurrence of fire has the characteristics of high frequency and large time and space span, and the loss caused by fire is also very serious. Firefight- ers must be exposed to high temperature, dense smoke, lack of oxy- gen and other harsh fire environment in fire fighting and rescue operations. Therefore, personal protective equipment such as fire masks and helmets are important equipment to avoid and reduce in- juries and deaths of firefighters. However, common fire masks do not have reliable cooling function, which can easily cause dizzi- ness, chest tightness and other symptoms to firefighters in hot and muggy environment for a long time, and even cause syncope or death in severe cases.
Aiming at the phenomenon, in the prior art scheme, the Chi- nese invention publication CN108578921a discloses an autonomous cooling type gas mask for a fire disaster, a cooling cavity of an air suction device of the gas mask is internally provided with a plurality of spiral air pipes which run through the cooling cavi- ty, the whole cooling cavity is internally hollow for accommodat- ing endothermic substances, a guide pipe is connected to the side wall of the cooling cavity, The conduit is connected to a material chamber mounted within the wearing assembly, the material chamber containing a reactant for reacting to form an endothermic sub- stance, thereby lowering the temperature of the inhaled air to protect the respiratory tract of the user. Chinese Utility Model
Publication CN211245266U discloses a fire-fighting mask, which comprises a hood made of fireproof fabric and a breathing tube with one end communicated with the inside of the hood. Based on the principle that hot air rises, the higher the horizontal height, the higher the temperature of the air. Because the other end of the breathing tube droops naturally when worn, The tempera- ture of the inhaled air will be relatively low, thus achieving a certain degree of cooling.
In the existing design scheme, the main problem is that the endothermic reaction is carried out by adding reactants for mix- ing, the endothermic substance is an irreversible substance, and the air suction device is also a disposable device, so that the air suction device needs to be replaced regularly, thereby causing certain resource waste. In addition, if the liquid in the cooling chamber is not sealed tightly, it is easy to cause leakage. Based on the physical principle of hot air rising, the horizontal posi- tion of air inhaled through the natural drooping breathing tube is far below the height of our head, and the cooling effect is not ideal. Therefore, it is necessary to propose a reliable and effec- tive fire mask cooling protection system and method to solve the above problems.
