Abstract
This invention provides a storage and automatic contraction and discharge device for a micro-liquid fuel battery including a shell set with a liquid charge nozzle and discharge nozzle on it, an elastic liquid-storage capsule is set in the shell connected with two nozzles, a regulating valve is set at the discharge part. The device can effectively control injection, storage and discharge of liquid fuels.
Description
(1) technical field
What the present invention relates to is a kind of fuel liquid battery fuel reservoir, specifically a kind of battery fuel storage and releasing device that is used for such as the field of the miniature portable power sources of all needs such as notebook computer, mobile phone.
(2) background technology
As far back as 1839, British William Grove has just proposed hydrogen and oxygen reacts the principle that can generate electricity.Baconic began the research work of fuel cell aspect and made the practical fuel cell of the first cover hydrogen-oxygen the 1950's.The sixties, the space technology of the U.S. was developed rapidly, and nineteen sixty-five and 1966 are in succession at " Gemini " and Apollo Personnel investigation Program " in the airship successfully Baconic's hydrogen oxygen fuel cell of application enhancements provide electric power for airship.The seventies, the appearance of energy crisis makes countries in the world pay attention to again the research of fuel cell, and the U.S., the former Soviet Union, Canada, Japan and other countries take the lead in researching and developing the fuel cell that ground is used.
It is supporting that the fuel supply system of present fuel liquid battery mostly is large-scale fuel cell, need supply fuel to battery by petrolift during fueling, is inconvenient to carry.
Early 1990s has proposed the notion of micro cell.Reported that U.S. a company developed micro fuel cell in 2003.This battery can be used in the products such as mobile phone, notebook computer.Methanol fuel cell has higher specific energy and energy conversion efficiency as a kind of minitype portable energy.Gu Ding external structure and the liquid fuel that can fill at any time also provide very convenient condition for the user simultaneously.But the structure of its bunkering and releasing device is not appeared in the newspapers.
(3) summary of the invention
The object of the invention provides a kind of good seal performance, working stability, reliability height, easy to carry and can store and releasing device for the micro liquid fuel battery fuel of fuel liquid battery makeup energy at any time.
The object of the present invention is achieved like this: it comprises shell, and shell is provided with fluid-filling nozzle, fluid mouth, it is characterized in that: be provided with elasticity liquid storage capsule in shell, elasticity liquid storage capsule is connected with fluid-filling nozzle and fluid mouth, and fluid mouth place has adjuster valve.
The present invention can also comprise some architectural features like this:
1, on the sidewall of shell, has watch window.
2, fluid-filling nozzle is a unidirectional valve.
Principle of the present invention is that the fluid-filling nozzle at apparatus surface is connected with its inner liquid storage capsule, the liquid storage capsule does not present tubulose when having liquid fuel to inject, the inner liquid storage sebific duct liquid fuel within of device injects the back elastic deformation takes place, overcome the convergent force of self and expanded, the expansion of sebific duct just forms the liquid storage capsule, stored liquid in the liquid storage capsule this moment, the result that the liquid storage capsule expands just forms extruding force to the liquid fuel of its inside, and this pressure liquid fuel within plays the effect of drain when discharging.When battery operated, can controlling liquid fuel trace input fuel cell by the flow control valve of regulating fluid mouth place.Present principles has been utilized the elastic deformation storage power of rubber material, has also stored liquid fuel simultaneously, and when discharging fuel, capsule produces elastic contractile force and drives liquid fuel discharge capsule.The present invention has good seal performance, working stability, reliability height, easy to carry and can be advantages such as liquid methanol fuel battery makeup energy at any time.
Core of the present invention is in device a liquid storage capsule to be set, the liquid storage capsule presents tubulose when not having liquid fuel to inject, after liquid fuel injects sebific duct, cause the expansion of sebific duct and form the liquid storage capsule, the result that sebific duct expands just forms extruding force to the liquid of its inside, and this pressure liquid fuel within plays the effect of drain when discharging.
The liquid storage capsule is to store liquid fuel, and after liquid fuel injected the liquid storage capsule by fluid-filling nozzle, fluid-filling nozzle was closed automatically, leaks with the liquid fuel that prevents to charge into.
Liquid fuel can be stored in the liquid storage capsule after charging into the liquid storage capsule for a long time, realizes the quantitative output of liquid fuel during use by the flow control valve above the adjusting fluid mouth.The controlled several microlitres/per minute magnitude that is made as of the minimum discharge of its discharge.
Liquid fuel in use reduces gradually, is the safe handling that guarantees fuel cell, can in time understand the consumption situation of fuel by watch window, according to the timely postcombustion of consumption situation.
(4) description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the vertical view of Fig. 1.
(5) specific embodiments
For example the present invention is done description in more detail below in conjunction with accompanying drawing:
The micro liquid fuel battery fuel is stored and the composition of self-constriction releasing device comprises shell 5, end at shell is provided with fluid-filling nozzle 7, the other end of shell is provided with fluid mouth 2, in shell, be provided with elasticity liquid storage capsule 3, elasticity liquid storage capsule is connected with fluid-filling nozzle and fluid mouth, and fluid mouth place has flow control valve 1.On the sidewall of shell, have watch window 4.Fluid-filling nozzle is a unidirectional valve.Liquid fuels 6 such as ethanol, methyl alcohol or formic acid add in the elasticity liquid storage capsule by fluid-filling nozzle.
