The present invention relates to a kind of solar charger, particularly relate to a kind of solar alkalescent Zn-Mn dry battery charger and a kind of cheaply, energy-storage travelling wave tube adopts the solar mobile phone charging device of built-in alkaline zinc-manganese dioxide cell.
(2), background technology:
Traditional charger or charger for mobile phone need adopt 220 volts of ac power supplies of standard usually, the place shelter must have mains supply, and for mobile crowds such as tourist, field works, their communication tool is not often because the environment shelter has alternating current and can not adopt conventional charger in time to charge.Along with the appearance of solar charger and solar mobile phone charging device, its advantage is more and more obvious, and progressively enters huge numbers of families.The problem that present various solar chargers exist is, energy-storage travelling wave tube built-in rechargeable batteries or lithium ion batteries of adopting wherein, charger cost are than higher more, in actual use can be because of overcharging or misoperation is brought potential safety hazard.China utility model patent ZL 03258227.7 (Granted publication CN 2648680Y, October 13 2004 Granted publication day) disclosed a kind of solar mobile phone charging device, comprise Mobile phone plug, shell, described shell is provided with photovoltaic cell, and described photovoltaic cell is connected with electrical storage device by reaction diode, and described electrical storage device is connected with Mobile phone plug by booster circuit, easy to use, and can prolong useful life of charger, utilize solar energy to give cell-phone charging, environmental protection, energy-conservation.But which type of electrical storage device application documents specifically openly do not adopt, because we know, not all electrical storage device can be used as the energy-storage travelling wave tube that can be recycled charge and discharge.Present in addition some solar charger, because it is technical immature, sometimes in order to give the internal battery full charge, also need to dispose an AC adapter and utilize civil power to give charging mobile phone battery to remedy the deficiency of solar recharging ability, this has limited it undoubtedly and has promoted the use of.
China utility model patent ZL 200620071339.1 (notification number CN 2904322Y, May 23 2007 Granted publication day) a kind of solar energy dry battery charger has been proposed, this charger comprises integrated circuit voltage regulator and box body, integrated circuit voltage regulator is positioned at the box body front portion, the box body rear portion is provided with battery case, charging is anodal to be positioned at battery case with the charging negative pole, box cover top is connected with solar panel, the input of integrated circuit voltage regulator is connected with negative electricity with the positive pole of solar panel by input lead, and the output of integrated circuit voltage regulator is connected with the charging negative electricity by output lead and charging are anodal.Utilize solar panel to charge, be not subjected to the restriction of AC power by integrated circuit voltage regulator.Having under the situation of sunlight, can charge at any time, easy to use, energy savings.The economic backward area and the rural area hillman that are particularly suitable for AC-less power charge to dry cell.With aforementioned same reason, this patent application does not have concrete open how the realization that dry cell is realized charging, because offer some clarification in the dry cell application notice: charge, lay in mistake or the input fire, all easily cause battery explosion or leakage.
A kind of quick charger is arranged in the market, and it is to utilize the energy of dry cell is applied to the purpose that reaches in the battery of mobile phone to charging mobile phone battery.Bringing for so the moving group of outgoing stream must be convenient, but used for dry cell crosses once and just can only throw away, and has caused the wasting of resources and environmental pollution.In fact, present alkaline zinc-manganese dioxide cell can be recharged, and it is made with complete charged state.But the main active substances of alkaline zinc-manganese dioxide cell is an electrolytic manganese dioxide, and the discharge that it has been generally acknowledged that first electronics is the homogeneous reaction that a proton and electronics move in lattice.Cause MnO
xX value only drops to 1.5 from 2.In this reaction, the MnO of solid
2Be converted into the another kind of solid structure MnOOH of trivalent:
MnO
2+H
2O+e→MnOOH+OH
