[0019] The fire escape equipment provided by the first embodiment of the present invention includes a mask for protecting the user's head and a supply device. A mouth and nose mask is arranged in the mask, and an air inlet / water inlet hose connector is arranged on the outside of the mouth and nose mask. A water inlet / air head for releasing clean air / or water supply to the oronasal mask is provided, and an exhaust hole for discharging air to the outside is also arranged on the oronasal mask, and a filter is arranged on the exhaust hole. The supply device supplies air and / or water to the inlet / water inlet hose connector of the oronasal mask through the pipeline.

[0020] figure 1 It is a schematic diagram of the axial section of the supply equipment of the fire escape equipment provided by the present invention. Such as figure 1 As shown, the supply equipment includes an inner cylinder 2 and an outer cylinder 1 arranged outside the inner cylinder. The cavity 3 in the inner cyl...

[0026] The fire escape equipment provided by the third embodiment of the present invention includes a mask for protecting the user's head and a supply device. The mask is provided with a mouth and nose mask. The inside of the mouth and nose mask releases the air intake hole of clean air, and the mouth and nose mask is also provided with an exhaust hole for discharging gas to the outside world, and a filter is arranged at the exhaust hole, and a water inlet hose connector is also arranged on the outside of the mouth and nose mask , The inside of the mouth and nose mask is also provided with a water supply head for drinking water for users. The supply device provides clean air to the inlet hose connector on the oronasal mask through the first pipeline, and supplies drinking water to the water inlet hose connector on the oronasal mask through the second pipeline.

Abstract

The invention relates to single-pipe supply fire escape equipment, and belongs to the technical field of fire control. The single-pipe supply fire escape equipment comprises a mask for protecting a user head, and supply equipment, wherein a mouth-nose cover is arranged in the mask; and the supply equipment provides clean air or water to the mouth-nose cover through a hose. The fire escape equipment, provided by the invention, can breathe fresh air even if in a fire scene, and can drink clean water, so that users can escape under the sober condition.

Description

technical field [0001] The invention relates to a fire-fighting and escape device supplied by a single pipe, which belongs to the technical field of fire-fighting. Background technique [0002] Fire is a major disaster that endangers thousands of households. According to data records, more than 80% of the people who died in the fire did not die from the fire itself, but were suffocated by thick smoke. In high-rise buildings, once a fire breaks out in a public place, the rescue work is very difficult. The strong irritating and toxic smoke generated during the combustion can make people lose their self-control ability in a short time, thus causing a large number of people to die in the fire. [0003] figure 1 It is a fire escape mask provided in the prior art. It usually includes a cover body 21, a mouth and nose mask 23 and a poison filter 22 made of high-temperature resistant and flame-retardant materials with a sealed upper end. The upper front end of the cover body is pro...
