Abstract
The utility model relates to a positive-pressure type fire escape breathing device which comprises an oxygen bottle, an antigas mask and a communicating hose connecting the oxygen bottle and the antigas mask. The antigas mask is provided with a viewing window. The positive-pressure type fire escape breathing device is characterized in that a pressure gauge and a reducing valve are arranged on the communicating hose. Due to the fact that a positive pressure structure is adopted by the positive-pressure type fire escape breathing device, the positive-pressure type fire escape breathing device enables escape personnel to be free of influences of external toxic smog, escape personnel can pass through a dense smoke area efficiently, and the escape success rate is improved greatly. The positive-pressure type fire escape breathing device is small in size, simple in structure, and convenient to store and use.
Description
Technical field
The utility model relates to a kind of positive-pressure type fire escape breathing.
Background technology
In social life, fire has become the threat public safety, a kind of multiple disaster of harm people lives and properties.And the most fatal in fire according to statistics be not directly burning of flame, but the asphyxiating death of dense smoke toxic smoke, and the fire of high-rise building rate of propagation is fast, easily form stack effect, the fire poison gas easily spreads to the fire escapes such as staircase fast, has a strong impact on people's evacuation speed and life security.Existing fire disaster escaping technical equipment mostly is the suction type breathing mask, can't normally use lower than 17% place at oxygen, and the incoming call resistance is also had to very high requirement, is not suitable for the weak old man of physique and child's use.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of positive-pressure type fire escape breathing of easy to carry, simple to operate and working stability.
The utility model adopts following technical scheme:
The utility model comprises oxygen cylinder, breathing mask and the connection flexible pipe that connects oxygen cylinder and breathing mask, on described breathing mask, is provided with visual windows, it is characterized in that also being provided with Pressure gauge and pressure-reducing valve on described connection flexible pipe.
Good effect of the present utility model is as follows:
The utility model adopts the positive-pressure type structure, is not subject to the impact of extraneous toxic smog, makes the escape personnel can efficiently pass through the dense smoke district, has greatly improved the escape success rate; And the utility model small volume, simple in structure, conveniently deposit and use.
The accompanying drawing explanation
Accompanying drawing 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, the utility model comprises oxygen cylinder 1, breathing mask 5 and the connection flexible pipe 3 that connects oxygen cylinder 1 and breathing mask 5, be provided with visual windows 6 on described breathing mask 5, it is characterized in that on described connection flexible pipe 3 also being provided with Pressure gauge 2 and pressure-reducing valve 4.The utility model adopts the positive-pressure type structure, is not subject to the impact of extraneous toxic smog, makes the escape personnel can efficiently pass through the dense smoke district, has greatly improved the escape success rate; And the utility model small volume, simple in structure, conveniently deposit and use.
