Abstract
A water resistant case (6) for an electrical device such as an electric wristwatch movement powered by a standard high current zinc/air cell. A small aperture (11) in the case wall slows ingress and egress of water vapor to the case so as to increase cell life. The aperture also limits the rate of oxygen flow to the cell cathode rather than the air entry ports in the cell itself. A hydrophobic gas transmissive membrane (45) admits air and water vapor to the aperture without admitting liquid water.
Description
The present invention relates to a kind of container that is used to utilize the electronic apparatus of metal air cell, this electronic apparatus design is suitable for the operation of harmonic(-)mean electric current but intermittently needs high electric current.An example of this container is a Watchcase, it comprises an electronic watch movement by the zinc-air cell power supply, and the continuous to-be low current is so that make wrist-watch as time meter operation, but this wrist-watch comprises and is used for (when by next button) device when illuminating, and perhaps makes the device of the radio receiver operation in beep-pager.Back one usefulness electronic apparatus needs quite high electric current in short-term when its work, therefore need the battery of high electric current to support.
Metal-air cell is known in the present technique field, and it comprises the nonexpendable negative electrode of the oxygen consumed that consumptive metal anode, catalysis use and suitable electrolyte usually.Metal-air cell is made by mini button button form, is used for hearing aids and wrist-watch and so on.A kind of typical zinc/air button is following part usually:
1 one negative electrodes, it can comprise the cathode construction that at least one hole is used as air intake and comprises the on-consumable air, this cathode construction one breathable hydrophobic polymer film, a metal confluxes grid pressure on this film; And comprise a waterproof porous catalyst material (for example activated carbon of the metal catalytic that mixes with bonding agent).But as one of battery independent actual part, the carrier ring of one or more Electolyte-absorptive is placed on the catalyst layer in this cathode construction, so that negative electrode and anode are separated.
2 one anode cassette, it can be incorporated into this negative electrode box by twisted knot usually, and comprises one usually by the spelter shape anode of the powder type of mixing mercury (for example containing 3-8%Hg by weight) or with the spelter shape anode of the form of the zinc briquetting that immerses alkaline electrolyte (aqueous solution that for example contains 30-40%KOH) porous.
The dividing plate of materials such as 3 one polyethylene, polypropylene, nylon, it is between negative electrode and anode cassette, and this dividing plate is under many circumstances also as seal.
Control to the air inflow of the anode that enters into consumed cabin air is to utilize at some apertures of button cell container to realize, as what introduced in authorizing No. 3897265 United States Patent (USP)s of Jaggard on 07 29th, 1975.This battery is applicable to the electronic apparatus of high relatively power consumption electric current (for example 10 milliamperes), for example is used in the hearing aids.Secondly,, researched and developed the zinc/air cell of long-life, low power consumption electric current, controlled the air inflow of the anode that enters into consumed cabin air by the diaphragm that adds a special use owing to the needs of electronic watch.By the so as can be known one type diaphragm that can see through oxygen of No. 4105830 United States Patent (USP)s authorizing Kordesch on August 8th, 1978.Authorize people's such as Przybyla No. 4118544 United States Patent (USP)s on October 3rd, 1978 and introduced a kind of like this scheme, it utilizes by very small hole or the passage of interlayer to negative electrode.
In all above-mentioned structures, the device that is used to control the air inflow of the anode that enters into consumed cabin air is to be specific utensil, or estimates the scope customization of the power consumption electric current that battery will adapt to.Above-mentioned structure is not suitable for changing the working method (or according to harmonic(-)mean current-mode or according to high current mode) of battery.
Formerly technology proposes: gas is entering and discharge of air or water vapour turnover zinc/air cell for example, can make it to slow down by making (required for making air enter into battery) the aperture throttling in cell wall.In order to extend the life of a cell, control relative humidity is particular importance.Zinc/air cell in the gaseous environment of low humidity and the rood under the state of high humility (Rood) will parch.This two states all hinders battery in long period of time, and (promptly under such a case, rated capacity would not exhaust in 6 week or below it) under the harmonic(-)mean consumption rate, realizes filling full rated capacity.The initial concentration of the electrolyte of battery has been established the internal relative humidity (RH) of battery near 58%.The battery of activation is exposed to the RH grade (being higher or lower than this numerical value) of surrounding environment, can causes that respectively water vapour enters or flows out.Water vapour enter or flow out can by reduce air admission hole size come the throttling restriction.But the aperture of the conveying of restriction water vapour has also been limited oxygen and has been transported in the battery.Its size of aperture in high galvanic cell must be adapted in order to keep the required oxygen air inflow of maximum discharge rate.
Having battery that the metal-air cell of high power consumption current capacity for example uses in hearing aids does not add to change and is not suitable for using in wrist-watch.Electronic apparatus for being used for needing harmonic(-)mean power consumption electric current usually but intermittently requiring high power consumption electric current improves metal-air cell.These more improved case introductions were authorized in No. 4262062 United States Patent (USP)s (having transferred applicant's assignee) of Zatsky on April 14th, 1981, and authorized in No. 5451473 United States Patent (USP)s of Oltman in September 19 nineteen ninety-five.In one patent of back, metal-air cell comprises the throttle membrane of a control from the air mass flow of (at entering of battery bottom inner gas storage cell) air intake.This gas storage cell provides enough oxygen to cathode assembly in one period of short time when battery bears high power consumption electric current.
Another kind is used to make battery and the device that the electronic apparatus that receives this energy content of battery mates, and is presented in No. 5191274 United States Patent (USP)s authorizing people such as Lloyd on March 2nd, 1993.In this patent, the quantity to battery air inlet or air fed hole controls by a seal, and the sealing part has determined the quantity in hole, opens some holes so that make oxygen can enter into the inside of battery.In all technology formerly, all be metal-air cell itself structures shape enter into the air mass flow of battery.
By formerly technology is also known, an electronic apparatus and metal-air cell (being complementary through the electricity consumption current requirements of design with electronic apparatus) are presented in the container.Owing to need provide air to make it work to battery, container can not be hermetic seal.Formerly technology allows common source of the gas to enter into container, so that satisfy the current requirements of electronic apparatus under all states.This air inlet is accompanied by water vapour makes the relative humidity in container fluctuate in wide range, by its several factors degree that exhausts oxygen of variation of temperature and battery in the variation of container external environment relative humidity, container for example.If yet electronic apparatus to stand excessive humidity or be intended for use underwater operation, liquid water also can enter container by air inlet passage.Knownly in chamber wall, utilize hydrophobic ventilative diaphragm, allow air not allow liquid water to enter.A case introduction that is used for this housing of instrument is authorized people's such as Kloss No. 4292681 United States Patent (USP)s on September 29th, 1981.People's such as Kloss patent disclosure a kind of container that is used for electronic apparatus, it has a lid and a seal, wherein or seal itself or hole in lid or housing itself can constitute by hydrophobic ventilative porous mass.
With reference to the Fig. 1 in the accompanying drawing, in No. 4292681 United States Patent (USP)s authorizing people such as Kloss, introduced a kind of container that is used for the technology formerly of electronic apparatus.Housing is made up of part 1 and 2, and wherein two housing parts utilize air-locked sealing ring 3 to be connected to each other together in the water-stop mode.Take the part 2 of cap form to be provided with a gas passage 4, it is by a hydrophobicity parts sealing that contains micropore.Air, oxygen and some components and parts (electronic apparatus and metal-air cell) are contained in case inside, provide air by these parts, and these parts can be for example be made of the polytetrafluoroethylene of non-sintering.Can also form several such can be by the air-vent of the seal sealing that contains micropore.For example, the zinc/air cell that is included in enclosure interior approximately per hour uses the air of 5 microlitres.Even in the immersion water, utilizing can continuous running at the air wrist-watch of enclosure interior.
Zinc/the air cell that continues in above-mentioned technical agency formerly is specially adapted to wrist-watch, if in the useful life of the practicality that it has, utilize those that for example in 4292681,5191274 and No. 5451473 above-mentioned United States Patent (USP)s, introduce in the air-flow throttle membrane of inside battery or with similar device.In the patent of Kloss, having used a kind of like this hydrophobicity breathable material form of diaphragm (usually with) is in order to limit entering rather than attempting the major limitation air or comprise the charge flow rate of other gas of steam of aqueous water.
Therefore, an object of the present invention is to provide a kind of improved container that is used for by the electronic apparatus of metal air cell, it prolongs the life-span of metal-air cell.
Another object of the present invention provides a kind of improved container, is used to prolong the life-span that the high power capacity metal-air cell of energy is provided to the electronic apparatus that needs the harmonic(-)mean electric current.
Another object of the present invention provides a kind of improved container, is used to control the variation of the relative humidity that is stood by the metal-air cell at internal tank.
Another object of the present invention provides a kind of improved method, is used for using one to be used for the standard zinc/air high-capacity battery of hearing aids type to the timepiece movement power supply that is included in waterproof case.
Briefly, the present invention comprises a container, be used to control to needing the harmonic(-)mean electric current and intermittently needing the electronic apparatus of high electric current that the air of high electric current metal-air cell of energy and the turnover flow of water vapour are provided, metal-air cell and electronic apparatus both are configured in this container, and the size of the air intake that metal-air cell has makes the flow of oxygen can obviously exceed battery for to the electronic apparatus that the needs the harmonic(-)mean electric current needed flow of powering.This container comprises the housing of a sealing, this housing defines a gas storage cell that comprises metal-air cell, the wall that the housing of sealing has define a throttling passage that between the environmental gas of gas storage cell and hull outside, is communicated with and size only make the flow of oxygen can fully satisfy the needs of electronic apparatus harmonic(-)mean electric current.According to its a kind of preferred form, this housing also comprises a hydrophobic ventilative diaphragm between the environmental gas that is configured in throttling passage and hull outside, and is suitable for stoping liquid to enter this housing and allows oxygen flow to go into throttling passage.In the preferred embodiment, throttling passage is the tiny hole in chamber wall, and its diameter is about 0.08 millimeter (0.0032 inch), is to be formed by the hole with GORE-TEX membrane covered.In addition, any other has hydrophobic ventilative suitable strip material and also can adopt.
Read following explanation in conjunction with the drawings and will be better understood other purpose of the present invention and advantage.
Fig. 1 is the simplification sectional arrangement drawing that the container that is used for electronic apparatus of technology formerly schematically illustrates with section.
Fig. 2 is the simplification sectional arrangement drawing that the container that is used for electronic apparatus and energy-storage battery according to the present invention schematically illustrates with section.
Fig. 3 is the view of simplifying, and represents a kind of improved form of the present invention.
Fig. 4 is the view of simplifying, and represents another kind of improved form of the present invention.
Fig. 5 is the view of simplifying, and represents another improved form of the present invention.
Fig. 6 is the view of simplifying, and represents another improved form of the present invention.
In Fig. 2 with the simplest form reduced representation according to container of the present invention.Seal casinghousing utilizes part 5 and 6 to constitute, and two housing parts utilize air-locked sealing ring 7 to be connected to each other also together in the water-stop mode.Electronic apparatus 8 is configured in enclosure interior, and this electronic apparatus need be by utilizing lead-in wire 10 energy-storage batteries that are connected thereto 9 that electric energy is provided.Because each characteristic shown in the figure is to represent in the mode of simplified schematic, does not represent mechanical structure and supporting part about electronic apparatus 8 or 9, should understand these all will need.Electronic apparatus 8 is intended to represent a kind of utensil for example for electronic watch movement or electronic instrument, and they need the low current of (2-250 microampere) in the continuous microampere order scope that is in so that a timing and the high electric current that also periodically or spasmodically needs to be in (2-12 milliampere) in milliampere level scope.An example is the beep-pager electronic watch, and it consumes about 5 microamperes stabling current, so that carry out clocking capability, but it needs the quite high electric current of 10 milliamperes of magnitudes spasmodically, so that carry out the beep-pager function.Because beep-pager only is to work sometimes, average power consumption electric current is low.
Energy-storage battery 9 is that a kind of high power capacity of standard or high electric current for example are used in the zinc/air cell (for example commercially available No. 13 batteries or No. 675 batteries) in the hearing aids, but does not utilize wherein a kind of scheme previously discussed that the air throttling that is provided to cathode construction is improved.Like this, after the lid that removes the air intake shown in 9a among the figure made it activation, the useful life of the high electric current zinc/air cell 9 of design was only in the magnitude in 3 to 6 weeks.
All such batteries are responsive to relative humidity and other atmospheric environmental parameters, and these atmospheric environmental parameters can change the chemical property in the battery, and battery performance variation and energy are exhausted too early.In the environment of low humidity, moisture be by evaporate in the electrolyte and by overflowing in the battery, reduced the quantity of electrolyte and finally caused dehydration.When high humility, will make battery obtain water, influence the dilution of electrolyte and finally overflow battery.In this example, the stability number (relative humidity is about 58%) of the relative humidity that to be battery attempted to keep by its inner chemical property of the dividing line between " low humidity " and " high humility ".Be higher than and be about 58% relative humidity, battery adds water; Be lower than and be about 58% relative humidity, the battery dehydration.By making water vapor diffusion enter the air intake 9a in cell wall and can realizing adding water and dehydration by its effusion.
Air also flows into battery 9 and owing to produces hydroxyl ion and oxygen consumed with the water reaction by air intake 9a.Be provided in the following table in the quantity of the air intake of typical commercially available high electric current zinc/air cell (hearing aids battery) and the example of size:
Hole (size) diameter always flows through area
Battery hole count millimeter (inch) square millimeter (square inch)
A 4 0.51 (0.020)0.82 (0.0013)
C 6 0.28 (0.011)0.37 (0.0006)
Permission obviously surpasses the electronic apparatus of battery to the harmonic(-)mean electric current that needs microampere order by the oxygen flow of above-mentioned air intake, but the interrupted high electric current that is in several milliamperes of orders of magnitude that can also fully provide electronic apparatus to need.
According to the present invention, utilize the turnover amount of a throttling passage 11 control water vapours and be used to keep the air inflow of air (oxygen) of the harmonic(-)mean electric current of electronic apparatus needs.Passage 11 is communicated with between the atmospheric environment of the gas storage cell 12 of housing inboard and hull outside.In the embodiment shown in Figure 2, the throttling passage hole that is included in a trickle boring in the metallic plate 13 or utilizes laser to form.Plate 13 sealing or be bearing in the inside in the hole 14 in the wall of housing parts 6 in addition.The throttling passage 11 that bears the suitable size of 2 milliamperes in harmonic(-)mean power consumption electric current is that diameter is 0.08 millimeter (0.0032 inch) or flow through the aperture that area is 0.005 square millimeter (0.000008 square inch).The usual range that is used for the hole diameter of throttling passage 11 is between the 0.05-0.1 millimeter, specifically depends on the harmonic(-)mean power consumption electric current of expection.This diameter can calculate or be determined by experiment.The air mass flow that aperture by this size enters gas storage cell 12 fully satisfies the needs of the lasting harmonic(-)mean electric current of electronic apparatus 8.Yet we have found that, this aperture also obviously hinder or the slowing down water vapour to the diffusion of gas storage cell 12 or by the outside diffusion of gas storage cell 12, and life-span that obviously prolongs metal-air cell.Even even block the high power consumption electric current of parts needs in this aperture or the electronic apparatus 8, gas storage cell 12 is the required air of battery 9 in a short time also.
