使用多种电源的电器
相关申请的引用
本申请要求享有2007年6月26日提交的美国临时专利申请No.60/946,230的优先权，其内容通过引用合并于此。
背景技术
许多不同的电器使用可充电电池组供电。例如，电钻、电锯以及其他电动工具通常使用可充电电池组供电。用户可以拥有一个以上的可充电电池组，从而可以在对用过的电池组进行充电时安装电力充沛的电池组。
虽然可充电电池组可以满足所需，但不可能更换到电力完全充满的电池组。另外，用户可能会处在不能充电的状况下，例如宿营。
发明内容
下面叙述本发明的一些实施方式的简要说明，从而提供对本发明的基本理解。所述说明不是对本发明的全面综述。所述说明不是用于确定本发明的关键部件，也不是用于限定本发明的范围。所述说明的唯一目的在于作为下文中叙述的一些实施方式的更详细说明的序言而通过简要方式叙述本发明的一些实施方式。
根据一种实施方式，电器接受多种不同的独立的电源。例如，电器可以容纳可充电电池组或被设计为容纳一次性电池的供电盒(power cartridge)。如果用户的电池组中没有足够的剩余电量，可以将一次性干电池放入所述供电盒并将所述供电盒插入所述电器以供电。
根据一种实施方式，另一种独立的供电盒可以包括燃料电池。该燃料电池供电盒可以包括可拆卸的燃料盒，例如，每个可拆卸的燃料盒中都具有燃料(例如氢)。

具体实施方式
下面将说明本发明的各种实施方式。出于说明的目的，阐述具体结构和细节以提供对实施方式的彻底理解。但是，对于本领域技术人员来说，可以不采用这些具体细节而实施本发明也是显而易见的。另外，省去或简化了公知的特征，以使具体实施方式的说明清晰。此外，关于所说明的实施方式的方位的界限，例如“上”、“下”、“前”、“后”、“右”等，这些方位用于帮助读者理解所说明的实施方式，而不是起限制作用。
根据一种实施方式，多种不同的独立的电源或供电盒设置为容纳在电器中并被电器使用。在附图中显示的实施方式中，电器为提灯20，但是其他电器也可以使用本发明。作为非限定性的例子，电动工具例如电钻或电锯可以使用本文说明的多种独立的电源。另外，其他便携式电器例如手电筒、便携式冰箱、便携式电扇和泵也可以使用所述多种电源。
本文使用的“独立的”供电盒或电源是不依赖于外部电源而自身提供电流的供电盒或电源。例如，独立的电源不需要插到AC输出口以供电。
在附图中显示的实施方式中，提灯20包括用于容纳供电盒例如可充电供电盒24的空腔22。该空腔22包括接点(未显示，但属于本领域公知的)，该接点用于在将可充电供电盒24插入空腔22时接合可充电供电盒24上的接点26。
可充电供电盒(例如可充电供电盒24)是公知的并通常被称为“可充电电池组”。因此，在此不说明其详细结构和组成。例如，可充电供电盒24可以使用SLA(密封铅酸电池)、NiMH(镍氢电池)、NiCd(镍镉电池)或锂离子可充电电池。
图2中显示了可充电供电盒24的底侧。可充电供电盒24包括插孔27和灯28。灯28可以用于例如显示可充电供电盒24已充满电。插孔27用于容纳适配器插头30，以对可充电供电盒24充电。适配器插头30可以连接到例如AC/DC适配器31(参见图3)或12伏车用适配器32(参见图4)。
可充电供电盒24形成为安装在空腔22内，并可以卡扣或锁止在所述空腔内。在可选择的实施方式中，可充电供电盒24可以安装在电器的外侧，可充电供电盒24可以包括安装在位于电器上的凹陷内的凸起，或者可充电供电盒24可以通过其他方式连接到电器。但是，通常来说，可充电供电盒24包括接点(例如接点26)，该接点与位于电器上的接点接合，所述可充电供电盒可以通过所述接点向电器供电。
根据一种实施方式，如图5和图6所示，设置有可以替代可充电供电盒24的一次性电池供电盒33。优选地，一次性电池供电盒33包括类似于接点26的接点。此外，一次性电池供电盒33的尺寸优选为与可充电供电盒24的尺寸类似或与可充电供电盒24的尺寸相同，从而使得一次性电池供电盒33也能够安装在提灯20的空腔22中。如果为可充电供电盒24设置锁止件或卡扣件，则也可以为一次性电池供电盒33设置类似的锁止件或卡扣件。
从图6中可以看出，一次性电池供电盒33包括铰接盖34，铰接盖34关闭时可以通过紧固件36(参见图5)和/或卡扣件连接。铰接盖34关闭用于次性电池供电盒33的室38。室38被设计为用于容纳一次性干电池40，例如四节D型一次性干电池(D-cell disposable battery)。一次性电池供电盒33可以被设计为能够安装任意数量的电池，包括只安装一节电池。
当铰接盖34关闭时，室38内的电池40通过传统的电路连接到位于一次性电池供电盒33的外侧上的接点。另外，如果需要的话，所述一次性电池供电盒可以包括变阻器或其他适当的装置，以调节通过一次性电池供电盒33向位于一次性电池供电盒33的外侧上的接点提供的电流。
在一种实施方式中，一次性电池供电盒33通过四节一次性干电池40提供6伏电压。在一种实施方式中，6伏电压也是可充电供电盒24的正常工作电压。因此，可以从提灯20上拆卸下可充电供电盒24并用一次性电池供电盒33代替，而不需要更换提灯20。通过这种方式，用户可以具有容易获得的另一供电盒，而不必充电和/或拥有额外的可充电供电盒24。当对可充电供电盒24充电时，用户可以使用一次性电池供电盒33。可选择地，用户可以继续使用一次性电池供电盒33并在需要时更换干电池40。另外，用户可以选择在电器(例如提灯20)中仅使用干电池40。
根据另一种实施方式，如图7和图8所示，电器(例如提灯20)中可以使用燃料电池供电盒44。燃料电池供电盒44包括壳体46，燃料电池(未显示)安装在该壳体46内。众所周知，燃料电池是电化学转换装置。燃料电池通过各种外部燃料(位于阳极侧)和氧化剂(位于阴极侧)产生电。这些燃料和氧化剂在电解质的作用下反应。只要保持必要的流量，燃料电池就能够良好、连续地工作。
在附图中显示的实施方式中，燃料电池通过可填充燃料盒48提供燃料。该可填充燃料盒48可以包括例如用于向燃料电池供电盒44供电的氢燃料。例如，可填充燃料盒48可以是金属氢化物(metal hydride)盒，以用于储存特别是在聚合物电解质膜(polymer electrolyte membrane(PEM))型燃料电池中使用的氢，或者用于储存特别是在直接甲醇燃料电池(direct methanolfuel cell(DMFC))型燃料电池中使用的甲醇/水混合物。
在附图中显示的实施方式中，燃料电池供电盒44可以设置在提灯20的空腔22内，以向所述提灯供电。因此，燃料电池供电盒44可以为电器例如提灯20提供可供选择的电源。
可以设置其他电源，包括直接连接到AC电源的供电盒(例如插头)。然而，本文中描述的独立的电源的优点在于使用该独立的电源的电器可以非常方便地携带，而不用受限于AC电源。
另外，根据一种实施方式，电器(例如提灯20)可以形成为能够容纳不同尺寸的供电盒和/或电源。例如，提灯20可以具有与空腔22分隔开的开口，该开口的尺寸设计为能够直接容纳一次性的干电池。可选择地，空腔22的尺寸可以设计为能够直接容纳一次性的干电池。
本发明的精神中包括其他改变。因此，虽然本发明可以接受各种改变和可选择的结构，但已经在上文中详细说明并在附图中显示了一种示例性实施方式。但是，应该理解的是，说明上述实施方式的目的不是将本发明限制为所公开的特殊形式，相反地，本发明涵盖落在如附带的权利要求中所限定的本发明的范围和精神内的所有修改、可选择的结构和等同情况。
除非文中另有说明或通过上下文明确表示相反意思，在说明本发明的上下文中(特别是在权利要求的上下文中)使用的“一”、“该”等类似用语应该理解为涵盖单个和多个。除非另有说明，用语“包括”、“具有”、“包含”、“含有”应该理解为开放式用语(即表示“包括但不限于”)。用语“连接”应该理解为部分或全部容纳在其中、连接到或连接在一起，包括存在插入关系。除非另有说明，文中说明的数值范围仅仅用于作为单独引用每个落入该范围内的离散数值的简单表述，并且每个离散数值都如同被在文中单独引用那样结合于说明书中。除非文中另有说明或通过上下文明确表示相反意思，文中说明的所有方法都可以按照任意适当的顺序实施。除非另有说明，文中使用的所有示例或者举例性语言(例如“例如”)仅仅用于更好地说明本发明的实施方式，而不是作为对本发明的范围的限制。文中的语言不应被理解为使任意非必要元件表示为实施本发明的关键部件。
文中描述了本发明的优选实施方式，包括发明人认为的实施本发明的最优方式。对于本领域技术人员来说，在阅读上述说明后可以对这些优选实施方式做出改变是显而易见的。发明人希望本领域技术人员采用适当的改变，而且发明人希望本发明不仅用文中特别说明的方式实施。因此，本发明包括适用的法律所允许的、在附带的权利要求中说明的主题的所有修改和等同物。另外，除非文中另有说明或通过上下文明确表示相反意思，上述说明的部件的任意可能的组合都包括在本发明的范围内。
