A self-contained antifreeze fire-fighting device for households under extremely cold conditions

Abstract

The invention discloses a household self-sufficient anti-freezing fire fighting device for extremely cold conditions. The household self-sufficient anti-freezing fire fighting device structurally comprises a respirator cartridge, a respirator auxiliary cartridge and a supporting isolation base; a pull ring matched with an internal vacuum bag is arranged at the upper end of the respirator cartridge, and a full face mask is installed in the vacuum bag inside the respirator cartridge; the respirator auxiliary cartridge and the respirator cartridge are attached and internally communicate the respirator auxiliary cartridge is internally provided with a heating fine filter net plate, clamping corners, fan blades, an inner bottom plate and a driving rotating shaft; the heating fine filter net plate is in contact with the extension end of the driving rotating shaft, and the extension end is located at the central position of the heating fine filter net plate in an electrical fit mode. According to the household self-sufficient anti-freezing fire fighting device for the extremely cold conditions, the respirator auxiliary cartridge and the respirator cartridge are matched, wherein the heatedfine filter net plate, the fan blades and the driving rotating shafts arranged in the respirator auxiliary cartridge act together, the heated fine filter net plate combines the air volume produced bythe fan blades, so that hot air is used for drying inner humid air, and meanwhile the function of anti-freezing is further realized.

Description

technical field [0001] The invention relates to the field of fire-fighting and security devices, in particular, it is a self-supporting anti-freezing and fire-fighting device for households under extremely cold conditions. Background technique [0002] Because it is used at home, it is necessary to provide a more convenient operation, because some people may have a relatively weak understanding of the use of fire-fighting devices. In order to provide self-rescue time to the greatest extent, one that is more convenient to use should be selected. The existing household fire-fighting equipment The equipment includes fire extinguishers, fire escape ropes, fire filter self-rescue respirators, etc. Among them, the fire filter self-rescue respirators are storage types. Once they are fixed and stored, it is necessary to ensure that the ambient temperature should be 0°C-40°C. There is no heat source around them and it is flammable. , Explosive and corrosive items, the ventilation sho...

[0002] Because it is used at home, it is necessary to provide a more convenient operation, because some people may have a relatively weak understanding of the use of fire-fighting devices. In order to provide self-rescue time to the greatest extent, one that is more convenient to use should be selected. The existing household fire-fighting equipment The equipment includes fire extinguishers, fire escape ropes, fire filter self-rescue respirators, etc. Among them, the fire filter self-rescue respirators are storage types. Once they are fixed and stored, it is necessary to ensure that the ambient temperature should be 0°C-40°C. There is no heat source around them and it is flammable. , Explosive and corrosive items, the ventilation should be good, no rain and moisture erosion, but in some relatively humid places in the north in the cold season, the storage of respirators will cause greater obstacles
