Abstract
The utility model discloses a portable chemical oxygen producing and saving device. The utility model comprises a container, a container cover which is provided with a safety valve, a filter, guiding tubes, buffering balls, a pneumatic control valve which is connected with a mouthpiece and the buffering balls, and the mouthpiece. When the utility model is used, the container cover is taken off, and the right amount of oxygen-producing agents, water, and catalyst are added into the utility model. The container cover is covered, the generant oxygen is mixed with the air in the pneumatic control valve after being filtered. Mixing air flows into the mouthpiece for the breathing of users. Because of the adoption of the pneumatic control valve, the utilization ratio of the oxygen is increased to 98%.
Description
The utility model belongs to medicochemistry oxygen producing and saving device, is applicable to that being particularly useful for highlands acute anoxia patient outside the hospital uses.
Existing chemistry produces the oxygen device, have in light weight, be easy to carry, advantage such as easy to use, but the oxygen supply that these chemistry produce the oxygen device all is open, along with expiration, the part of oxygen of supplying with is breathed out thereupon, the utilization ratio of oxygen supply has only about 50%, and under the oxygen source condition of limited, the utilization ratio that improves oxygen seems more outstanding.
The purpose of this utility model is to overcome existing chemistry and produces the deficiency that the oxygen device exists, and a kind of portable chemical oxygen producing and saving device that can improve coefficient of oxygen utilization is provided.
The utility model is achieved in that the conduit that can adorn the container of oxygen producing agent, the container cover that safety valve is housed, strainer, buffering ball in one, link to each other with strainer with buffering ball, forms portable chemical oxygen producing and saving device with pneumatic control valve and mouth mask that buffering ball links to each other with mouth mask.Said pneumatic control valve be by cylinder sleeve, one be positioned at cylinder sleeve axle center and the slide bar that fixes with cylinder sleeve two ends air inlet/outlet fulcrum, piston that places on the slide bar and can move forward and backward thereon, one be positioned at position, one side direction outside bulge, cylinder sleeve air outlet one end and its fixing oxygen valve of linking to each other with lever of the other end, the other end that links to each other with oxygen valve is lever that forked, slide bar walk betwixt and one and is positioned at the exhaust prevention diaphragm composition that cylinder sleeve air outlet one side links to each other with slide bar; The flow indicator valve is housed in the described strainer.
The utlity model has following advantage:
1, the utility model has adopted pneumatic control valve, makes coefficient of oxygen utilization bring up to 98%.
2, the utlity model has a good buffering ball of elasticity, not only reduced the requirement of withstand voltage of whole product oxygen device, but also can be from one of the buffering ball easier situation of producing oxygen and user's oxygen uptake of observing that contracts that rises.
3, oxygen producing agent of the present utility model can repeatedly be changed, and this device can use repeatedly.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:
Fig. 1 is an overall schematic of the present utility model
Fig. 2 is the diagrammatic cross-section of pneumatic control valve end-tidal of the present utility model
Fig. 3 is the diagrammatic cross-section at the air-breathing end of pneumatic control valve of the present utility model
Adopt plastics or metal to make container ［ 1 ］, also can be with canteen as container ［ 1 ］, the container cover ［ 2 ］ that has safety valve ［ 3 ］ is equipped with in container ［ 1 ］ outlet, container cover ［ 2 ］ engages with strainer ［ 7 ］, pneumatic control valve ［ 9 ］ is connected with buffering ball ［ 8 ］, mouth mask ［ 10 ］, connects strainer ［ 7 ］ and buffering ball ［ 8 ］ composition portable chemical oxygen producing and saving device with conduit ［ 6 ］.
Pneumatic control valve ［ 9 ］ and circular cylinder sleeve ［ 16 ］ adopt plastics or metal to make, and a side of cylinder sleeve ［ 16 ］ is convex, and the internal diameter of cylinder sleeve ［ 16 ］ is less in inlet mouth one side, and air outlet one side is bigger.Be provided with a slide bar ［ 14 ］ in cylinder sleeve ［ 16 ］ inner axes position, its two ends fix with cylinder sleeve ［ 16 ］ air inlet/outlet fulcrum respectively.Be equipped with piston ［ 12 ］ on the slide bar ［ 14 ］, the diameter of piston ［ 12 ］ is slightly less than the internal diameter of cylinder sleeve ［ 16 ］ inlet mouth end, and piston ［ 12 ］ can move around on slide bar ［ 14 ］.Be built-in with oxygen valve ［ 13 ］ in position, one side direction outside bulge, cylinder sleeve ［ 16 ］ air outlet, one end and cylinder sleeve ［ 16 ］ fix, and the other end links to each other with lever ［ 15 ］.The end that lever ［ 15 ］ stretches in the cylinder sleeve ［ 16 ］ is forked, and slide bar ［ 14 ］ is walked therein, and lever ［ 15 ］ can move around and swings the Push And Release of control oxygen valve ［ 13 ］ with piston ［ 12 ］.Have an exhaust that links to each other with slide bar ［ 14 ］ to stop diaphragm ［ 17 ］ in cylinder sleeve ［ 16 ］ air outlet one side, this diaphragm is made by rubber.The similar medical mouth mask of mouth mask ［ 10 ］ ［ 10 ］, mouth mask ［ 10 ］ one sides have vent valve ［ 11 ］, the air inlet side of mouth mask ［ 10 ］ is connected with pneumatic control valve ［ 9 ］, the other end of pneumatic control valve ［ 9 ］ is connected with the buffering ball of being made by rubber ［ 8 ］, by conduit ［ 6 ］ buffering ball ［ 8 ］ is linked to each other with strainer ［ 7 ］ again.Filtering material and flow indicator valve ［ 5 ］ are housed in the strainer ［ 7 ］.
During use, take off the container cover ［ 2 ］ of this device, a certain amount of oxygen producing agent ［ 4 ］ is added in the container ［ 1 ］, add an amount of water and catalyzer again, covered container lid ［ 2 ］, the oxygen that produces enters buffering ball ［ 8 ］ by the filtering material and the flow indicator valve ［ 5 ］ of strainer ［ 7 ］ through conduit ［ 6 ］.When air-breathing, piston ［ 12 ］ moves backward at suction function lower edge slide bar ［ 14 ］, the lever ［ 15 ］ that promotes simultaneously on the oxygen valve ［ 13 ］ is opened oxygen valve ［ 13 ］, air ［ A ］ and oxygen pour in the cylinder sleeve ［ 16 ］ simultaneously, mixed gas ［ C ］ enters in the mouth mask ［ 10 ］, breathes usefulness for the user.During expiration, piston ［ 12 ］ and oxygen valve ［ 13 ］ are in closing condition, and waste gas is discharged from vent valve ［ 11 ］, and exhaust stops diaphragm ［ 17 ］ to stop waste gas to return in the cylinder sleeve ［ 16 ］ of pneumatic control valve ［ 9 ］, and pneumatic control valve ［ 9 ］ restores to the original state again.
