Description
Technical field
The utility model relates to a kind of breathing equipment, and particularly a kind of fire danger-avoiding is from auxiliary respirator.
Background technology
Frequent meeting breaking out of fire accident in life; and in fire fatality accident; die from the number more lethal than directly burn with the number of poison gas of suffocating much more; this is because when fire occurs; comburant discharges pyrolysis in a large amount of carbon monoxide or hot environment and goes out toxic gas or smog; the corpuscular property that these combustion products may occur with cigarette form, also may be invisible toxic gas, these toxic gases can allow body people's death by suffocation in a fire.Wherein modal poison gas is carbon monoxide, it is that scene of fire threatens maximum deathlike atmosphere, this is because the carbon monoxide that human body sucks lung can be combined by the ferroheme in blood, replace the oxygen be originally combined with ferroheme, thus greatly reduce the function of ferroheme transport oxygen in blood, make people absorb less than required oxygen and cause breathing to be obstructed from bottom to top, anoxic illness occurs thus causes death.Current existing professional air rubber capsule (oxygen bag) acquisition cost is very high, and generally only have fireman to be just equipped with, ordinary people does not generally have this kind equipment, can only cover nose face and wait for fire-fighting and rescue, but this worry cigarette effect is very limited with wet water fabric.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of easily and effectively, cheap fire danger-avoiding is from auxiliary respirator.
The technical scheme solved the problems of the technologies described above is: a kind of fire danger-avoiding is from auxiliary respirator, comprise air intake duct, face shield, also comprise three-way pipe, pump gas cylinder, flexible pipe, described three-way pipe comprises A end, B end and C end, wherein the A end of three-way pipe is connected with air intake duct, B end is connected with pump gas cylinder, and C end is connected with one end of flexible pipe, and the other end of flexible pipe is connected with face shield; Described air intake duct and three-way pipe A hold the one end be connected to be filter end, are provided with medium in filter end, and the other end of air intake duct is blank pipe free end, is movably connected between this blank pipe free end and filter end of air intake duct.
Further technical scheme of the present utility model is: described medium is followed successively by net, absorbent cotton, active carbon.
Further technical scheme of the present utility model is: A end, the C end of described three-way pipe are respectively arranged with check valve I and check valve II, and described flexible pipe is provided with check valve III in the face junction with face shield, and face shield is provided with check valve IV at nose place.
Further technical scheme more of the present utility model is: the blank pipe free end of described air intake duct is made up of telescoping tube.
Owing to adopting said structure, the fire danger-avoiding of the utility model from auxiliary respirator compared with prior art, has following beneficial effect:
1. easy to operate:
The utility model comprises air intake duct, face shield, three-way pipe, flexible pipe, pump gas cylinder, is provided with medium in the filter end of wherein air intake duct.When fire occurs, Dark smoke billows, trapped personnel takes out this respirator, face shield is enclosed within the face and tie up, move on to safer place, window is passed through according to wind direction, balcony reaches the fresh place of toxic smoke outer air the blank pipe free port of air intake duct, then according to the frequency extrusion pump gas cylinder breathed, when extrusion pump gas cylinder, check valve I is promoted by air pressure and closes, the interior safety air of bottle flows to face shield by check valve II and check valve III and supplies people to breathe or flow out face shield by check valve IV simultaneously, when staff unclamps pump gas cylinder, pump gas cylinder relies on natural resiliency to recover and expand, in bottle, gas atmosphere reduces rapidly, compressing due to outer air pressure pushes away closes check valve II and check valve III and check valve IV, people is made not to be drawn onto the toxic air of surrounding, check valve I is pushed open by outer air pressure simultaneously, outer air pressure is pressed into three-way pipe the safety air of outside along air intake duct, pump gas cylinder is (the fresh air inspiration three-way pipe of outside, pump gas cylinder), period, the medium of air intake duct just created effect, that rises to a certain extent is clean, filter the effect of toxic smoke, ensure and suck three-way pipe, pump gas cylinder be ozone or comparatively safe air.When extrusion pump gas cylinder again, check valve I is promoted by air pressure again and closes, all the other one-way valve opens, this ozone or comparatively safe air will arrive along the C port of three-way pipe nose and the face that face shield enters trapped personnel, and people just complete whole respiratory.Thus can have little time to use high building escape equipment or under using the ill situation of high building escape equipment, can temporarily use this draw the outer clean air of toxic smoke from auxiliary respirator or filter toxic smoke Hold up voltage, to wait for fire-fighting and rescue.Owing to being movably connected between the filter end of air intake duct and blank pipe free end, detachable, when likely going out toxic smoke district, removes rapidly blank pipe free end, flees from fire threat district with this device.Therefore, the operation of this respirator is more convenient.
2. safe and effective:
Because the utility model is provided with three layer filtration material in the filter end of air intake duct: net, absorbent cotton, active carbon, toxic gas can be filtered out, what ensure that trapped personnel sucks is all fresh safety air; And by the setting at check valve, also effectively ensure that gas can not flow backwards away.
3. structure is simple, economical and practical:
Because the utility model comprises air intake duct, face shield, three-way pipe, flexible pipe, pump gas cylinder, wherein be provided with medium in air intake duct, its structure is very simple, without the need to the parts of other complexity, both economical material benefit, can promote the popularization use in ordinary people family, indicator of trapped personnel is more ensured.
Below, in conjunction with the accompanying drawings and embodiments the fire danger-avoiding of the utility model is further described from the technical characteristic of auxiliary respirator.
