Abstract
The utility model discloses self -supporting oxygen formula protective face mask relates to the self -supporting oxygen inhalation apparatus of brand -new isolated formula that utilizes chemical mode system oxygen, utilizes chemical mode to prepare the isolated formula protective face mask that oxygen simultaneous reaction jar can continuous seamless change. The utility model has the characteristics of but small, light in weight continuous operation. This equip to solve bulky, the shortcoming big, can not the continuous operation of bearing a burden of current protector material. Can increase substantially the throughput that epidemic prevention army handled the proruption epidemic situation.
Description
Technical field
This utility model relate to the use of chemical mode oxygen can anti-biological pollution isolation type one wear breathing apparatus,
Espespecially a kind of portable from oxygen offering type protective mast.
Background technology
Existing isolation type mask is mainly in high concentration contamination air both at home and abroad（When volumetric concentration is more than 1 %）In, or
The high-altitude of anoxia, use under water or under the special occasions such as closed in space；Mask provides oxygen in itself by mask mostly, point air storage
Formula, storage oxygen formula and chemical 3 kinds of oxygen-producing type.Wherein：
（1）Gas storage, storage oxygen formula gas mask are by loading gas cylinder after compressing air or oxygen, logical during use
Crossing the compressed gas that vent valve slowly discharges in gas cylinder supplies people to breathe, and the breathing gas providing are gas at normal temperature, and breathing is relaxed
Adaptive is stronger, but need to wear a gas cylinder, increased the operation easier of user and wears heavy burden；
（2）Mining chemistry self-rescuer adopts potassium superoxide oxygen generating agent, reacts life by the carbon dioxide of exhalation with oxygen generating agent
Become the chemical reaction of oxygen, provide oxygen for user, mining chemical oxygen self-rescuer small volume, lightweight, using simple, but deposit
In the problem that oxygen generator temperature is high, the gas drying of generation, use time are short.
Content of the invention
This utility model aims to overcome that generalization length of schooling oxygen inhalation apparatus working time short shortcoming, provides a kind of employing
Potassium superoxide as oxygen generating agent, is reacted generation oxygen by the carbon dioxide with characteristics of contaminated respiratory droplets, user of service is carried out every
From protection, realized by face seal interface simultaneously retort seamless replacing from oxygen offering type protective mast.
To achieve these goals, this utility model adopts following technical scheme：
A kind of from oxygen offering type protective mast, mainly by main frame（1）, retort（2）, oxygen candle trigger（3）, bladder tank（4）、
Mask（5）, video recorder（6）Composition, wherein：Main frame（1）Upper setting aerobic candle trigger（3）, main frame（1）With retort
（2）Connected by gas circuit, flexible pipe（7）One end connects main frame（1）, other end connection mask（5）, bladder tank（4）Storage produces
Oxygen, retort（2）With main frame（1）The draw-in groove of bottom（8）Connect.
Described retort（2）Front is worn or loins is worn.
Due to adopting technique scheme, this utility model has advantages below and effect：
a）This utility model has small volume, lightweight portable feature from oxygen offering type protective mast；
b）This utility model developed from oxygen offering type protective mast have retort front wear and retort loins wear
Wear two kinds of mode of operations, unrestricted choice can be accustomed to according to use environment and user；
c）This utility model has the characteristics that continuous seamless to change retort, and guard time is unrestricted；
d）There is no the achievement Report same with this item class at present both at home and abroad, illustrate original from the development of oxygen offering type protective mast
Property.
Brief description
Fig. 1 is this utility model structural representation；
Fig. 2 wears side view for this utility model front；
Fig. 3 wears schematic diagram for this utility model loins；
Fig. 4 wears side view for this utility model loins.
Specific embodiment
Illustrated by Fig. 1-Fig. 4, a kind of from oxygen offering type protective mast, mainly by main frame 1, retort 2, oxygen candle trigger 3, storage
Airbag 4, mask 5, video recorder 6 form, wherein：Setting aerobic candle trigger 3 on main frame 1, the titanium dioxide of user exhalation
Carbon and steam are entered retort 2 by the gas circuit of main frame 1 and are reacted with the potassium superoxide in tank, enter air storage after producing oxygen
Bag 4 is supplied to user and uses, and flexible pipe 7 one end connects main frame 1, and the other end connects mask 5, the card of retort 2 and main frame 1 bottom
Groove 8 connects, and when in retort 2, oxygen-making agent is depleted, with new retort, empty retort is replaced realization from oxygen offering type protection
The continuous work of mask.
From during the use of oxygen offering type protective mast：
a）According to use habit and use environment, before selective response breast, wearing mode or loins wearing mode connect gas
Road；
b）Wear mask, tighten up mask band below it is ensured that mask surrounding is fitted with face, reach sealing；
c）With handss, oxygen candle trigger drawstring is pulled off, oxygen candle trigger will start and discharge oxygen into bladder tank.
Enter normal operating conditions from oxygen offering type protective mast, when user feels that oxygen concentration is not enough, take out new
Retort, on the left of old retort align, firmly promote to the right, make new retort replace old retort, mask enter
The new working cycle, repeating this operation can the unconfined prolongation isolating and protecting time.
Claims (2)
1. one kind is from oxygen offering type protective mast, mainly by main frame（1）, retort（2）, oxygen candle trigger（3）, bladder tank（4）, face
Cover（5）, video recorder（6）Composition it is characterised in that：Main frame（1）Upper setting aerobic candle trigger（3）, main frame（1）With reaction
Tank（2）Connected by gas circuit, flexible pipe（7）One end connects main frame（1）, other end connection mask（5）, bladder tank（4）Storage produces
Oxygen, retort（2）With main frame（1）The draw-in groove of bottom（8）Connect.
2. according to claim 1 from oxygen offering type protective mast it is characterised in that：Described retort（2）Front is worn
Or loins wears.
