Description

可更换燃料盒的打火机及其可¥换燃料盒 技术领域
本发明涉及一种打火机， 更具体地说涉及一种具有可更换燃料盒的打火 5 机， 打火机采用可更换燃料盒， 以一个满载的燃料盒替换一个空燃料盒， 因 而在经济划算的时候使打火机寿命得以最大的延长。 背景技术
打火机是代替火柴点燃香烟和雪茄烟的普通工具， 通常有二种打火机：0 即产生可见火焰的普通打火机和产生喷焰的喷焰打火机。 不管使用哪一种打 火机， 打火机必须包含有供应燃料的液化气燃料储存器， 以便燃烧后提供火 焰或喷焰。
一种常规的液化气燃料储存器具有一个与喷嘴相通的释放阀和一个加 气阔， 用于经过此阀、 以这样一种方式来再填充燃料， 即当打火机的燃料用5 尽时， 使用者可以借助充气瓶再充填燃料。
众所周知， 在正常状态下燃料是气态， 而当在高压下存储到打火机的液 化气储存器中时则为液态。 为了再充填燃料， 加气阀必须与充气瓶的尖端配 合这样的充气瓶提供高压通过加气阀将燃料灌入液化气燃料储存器中。但是， 在充气操作的过程， 燃料可能在充气瓶的尖端泄漏。 因为燃料是诸如丁烷之0 类的易燃混合物， 因此， 特别是当在厨房中靠近水池或指示灯再充填打火机 是极其危险的。 此外， 在充填操作时难以避免燃料的泄漏， 因此使用者可能 吸入泄漏的燃料。 这对使用者的健康是有害的。
此外， 使用者不可能确定液化气燃料存储器是否被燃料完全充满， 即便 它已经满了， 使用者也可能持续将燃料向液化气燃料储存器中充气， 这是燃5 料的浪费， 除此而外， 对使用者来说， 到处带着充填瓶是费劲的。
在日本专利文献 JP2001-12737A中公开了一种可更换燃料盒的打火机。 在此方案中， 燃料盒和上部结构可以自由拆换。 但其燃料盒 3必须与上部结 - 构 2靠其专门构件 4、 5间相对旋转才能固定，两者要通过该专门结构彼此相 " 对旋转才可拆幵， 在更换燃料盒时， 还需将外壳完全拆下。 因此， 其结构相 对来说较为复杂。 而且， 还必须卸下外壳才可拆装燃料盒， 使用起来不太方 便。
本申请人在一个已授权的中国专利申请 02116399. 5及其附图 1-6中公开了 一种可更换燃料盒的打火机。在此方案中，燃料盒和上部结构可以自由拆换， 只要将壳体 10底部的门 15打幵就可以将本案打火机的燃料盒取出或将其插 入壳体 10中，随后将门关上就可完成更换燃料盒的操作。故其结构比较简单， 操作较为为方便。 但是由于充气打火机的气体释放阀均向上拔气门才能释放 气体， 故此专利不能采用常规的气体释放阀而制作成本较高。 为此本申请人 又对之进行了一系列改进， 提出了一种新结构的打火机及可更换燃料盒。 已 授权的中国专利申请 02116399. 5 用作本申请的参考文献。 发明的公开

本发明的另一个目的是提供一种具有可更换燃料盒的打火机， 它可防止 从燃料盒到喷嘴之间的被释放燃料的泄漏。
本发明的另一个目的是提供一种具有可更换燃料盒的打火机， 使用者通 过简单地插入一个新的充满燃料的盒就能够用打火机点火。
本发明的另一个目的是提供一种具有可更换燃料盒的打火机， 通过更换 燃料盒来再充填打火机从而在新燃料被更换之后确保打火机是被完全预充满 的。
本发明的另一个目的是提供一种具有可更换燃料盒， 它与本发明的打火 机配套使用。

一个支承在该壳体顶板上、 用于产生朝向该喷嘴的火花的点火系统； 其特征在于， 一个气体释放杆以枢轴运动方式被支承在所述可更换燃料 盒上， 该杆具有一个与所述可更换燃料盒上的气体释放阀相配合的致动末端; 和一个驱动末端，当该驱动末端被压下時，该致动末端以枢转运动方式向上抬 升所述气体释放阀而从所述的可更换燃料盒释放出被液化气燃料； 以及
一个气体释放装置， 它具由一个以可转动方式支承在所述的壳体上的致 动器,它与所述气体释放杆的驱动末端连接的方式使得在该致动器被转动而 压下该驱动末端时， 所述气体释放阀就朝所述喷嘴释放点火用气体。
所述的致动器具有一个安装在所述壳体上、 用于关闭打火机的打火机盖 及一个驱动杆， 此驱动杆有一个与所述打火机盖相连的上部及与所述气体释 放杆的驱动末端以可滑动方式连接的下部， 它们相互连接得当打火机盖向上 作枢转运动裸露打火机顶板時， 所述驱动杆就被驱动而将气体释放杆的驱动 末端压下， 从而使可述气体从可更换燃料盒中被释放。

5 图 1-6 是本发明所引用的参考文件、 本申请人的已授权的专利申请
02116399.5 的第一、 二实施例附图， 所以不再详细对之说明。
图 7-10展示本发明的最佳实施例的打火机， 其中的打火机为， 例如为常 规的打火机， 它包括一个具有接受腔 11"的壳体 10"和一个将接受腔 11"与外 界沟通的开口 12"， 以及在壳体 10"的顶板上的气体发射喷嘴 20"， 打火机还0 包括燃料供应装置 30"和点火系统 40"。
燃料供应装置 30"包括一个经过开口 12"可拆卸地容纳在接受腔 11"中 的、用于储存一种液化气的燃料的可更换燃料盒 31"; 从可更换的燃料盒 31" 延伸出的並与气体喷嘴 20"相連的气体释放阀 32"，此阀用以控制从可更换的 燃料盒引来的气体流;以及一个气体释放杆 33"， 该杆以一种可转动地运动方5 式支承在燃料盒 31"上，它与气体释放阀 32"连接、用于操控气体释放阀 32"。
气体释放杆 33"最好做成一个可枢轴转动的杠杆， 它从气体释放阀 32" 延伸出来並伸入到接受腔 11"， 並且在燃料盒插入该接受腔后， 气体释放杆 33"还可在壳体 10"内作枢轴转动。 亦即是说， 气体释放杆 33"有一个用于使 气体释放阀 32"移动的致动末端 331"，而且驱动末端 332"延伸入壳体 10"内，0 以便使致动末端 332"受压后能使致动末端 331"被抬升而使气体释放阀 32"移 动。
本实施例的打火机还有一个气体释放装置 50"， 它支承在壳体内、 用于 控制气体释放杆 33"。 气体释放装置 50"有一个致动器， 用于将气体释放杆 33，，的驱动末端 332"向下压。
:； 该致动器有一个以可枢转方式安装在壳体 10"上的打火机盖 51"，它用于 关闭壳体 10"的顶端部;及一个以可枢转方式安装在壳体 10"内的驱动杆 52", 其上端与该打火机盖相连， 下端与气体释放杆的驱动末端 332"滑动接触， 从 而可使气体释放杆运动。当打火机盖向上转动使壳体 10"敞开時，驱动杆 52" 就被驱动而压下杆 33"， 使气体从燃料盒中放出。
0 如图 8所示，打火机盖有一个可相对壳体 10"转动的枢转端 511"。 当打 火机盖向上放转动使壳体 10"敞开時，此枢转端就向内转动而靠压驱动杆 52" 的上端部， 使此驱动杆顺时针转动。 这样就使此驱动杆的向外转动的部分向 下压气体释放杆 33，，的驱动末端 332"向下压， 从而使气体从气体释放阀 32" 放出。
3 值得注意的是： 该致动器可以是与气体释放杆 33"的驱动末端联动的点 火按纽， 以便在此点火纽压下而产生火花的同时， 也使驱动末端 332"向下压 而使打火机点着火。
而且气体释放阀 32"有一个向上延伸的操作端 321"。 当气体释放杆 33" 的驱动末端 332"向下压時， 阀 32"就从能料盒 31"中放出燃料。 在本实施例 中， 当气体释放杆 33"的驱动末端 332"向下压時， 阀 32"就从燃料盒 31"中向 气体喷嘴 20"放出燃料。
燃料供应装置 30" 还具有一个与气体释放阀 32"连接的防护帽 34"。 为 了将气体从气体释放阀输送到气体喷嘴， 此帽具有一个与气体释放阀的可动 操作端 321"以可拆卸方式配合的内腔 341"; 及有一个通过内腔 341"延伸出的 槽 342"、 与可动释放阀的操作端 321"对准的导件。
如图 9 所示,气体释放杆的致动末端 331"还与气体释放阀可动操作端 321"的颈部 322"相联,以便在驱动末端 332"被下压時,致动末端 331 "能够被抬 升而将可动操作端 321"对着防护帽顶部轻轻推动， 从而使贮存在燃料箱内的 燃料能够通过该帽经槽 342"被释放至喷嘴处被点燃。 换句话说， 气体释放阀 的可动操作端 321 "通常是处在如图 9所示的下面的闭合位置上的， 当气体释 放阀的可动操作端 321"被驱动到如图 10所示的上面的位置上时， 可动操作 端 321"就被安置得可使气体从燃料盒 31"中向喷嘴 20"释放。
防护帽 34"还有一个密封件 343"， 它呈环状、 被同轴地安装在内腔 341" 中， 用于密封安装气体释放阀的可动操作端 321"， 从而防丛气体从防护帽中 向外泄出。
应该注意：可更换的燃料盒 31"还有一个对气体释放杆 33"施加推力的机 构来将致动末端 331 "向下推。 该推力机构就是一个置于驱动末端 332"下面、 由壳体支承的弹性件 35"， 用于连续地向上推压驱动末端 332"。 因此， 驱动 末端 332"在正常情况下是被向上推压的，以礁保可动操作端 321 "处于密封位 置上。
密封帽还直接与一个气体传送管 36"连接，管 36"的另一端用于连接气体 喷嘴 20"。值得一提的是： 管 36"是一个如橡胶一类的柔性气体管道， 从而允 许气体朝喷嘴 20"流动。 在防护帽被向上推、 处于气体释放期间時， 此防护 帽允许管 36"随防护帽 34"自由运动。燃料供应装置最好还有两个支承在壳体 10"内的导壁 37"。 该防护帽 34"以可滑动方式安装两导壁 37"之间、 且可滑 行一预定离。 如图 9-10所示， 每个导壁均有一个与此导壁一体形成的、 向内 的止挡突 371"， 以便在可动操作件被抬升而迫使防护帽 34"向上移动時， 止 挡突 371"能自动地限制防护帽的移动距离。
防护帽 34"最好还有一个帽突,肩 344"， 它沿此帽圆周方向向外突伸。 这 样就可在可动操作端 32Γ向上抬升、 沿导壁 37"向上轻推此防护帽時， 使从 导壁向内延伸的止挡突 371 "在防护帽向上移动期间能延滞该防护帽的向上 移动及制止该帽继续向上运动。
此外， 为了确保延长寿命及性能可靠， 燃料供应装置 30"还如图 11-12 所示那样，在横向止挡突 371 "与帽突肩 344"之间置有弹性件 38"。这样一来， 5 在点火期间， 向上移动的防护帽就能挤压该弹性件。在使用者松开致动器后， 弹性件 38"就被松开而迫使防护帽 34"与止挡突 371"脱开。 亦即是说， 弹性 件 38"用于使防护帽 34"永远在适合位置上垂直移动。在点火操作完成后，被 向上推动的防护帽 34"能返回起始位置， 以便下一次再点火操作。
弹性件 38"可以是从每个止挡突底部向下延伸出的两个弹簧，帽突肩 38"0 与弹簧以可拆卸式反复结合而可平稳地返回。 此外， 弹性件 38"也可以是一 个套在防护帽上被帽突肩 38"支承的螺卷簧。当该防护帽一旦被向上推动時， 此螺卷簧就被夹在止挡突 37与帽突肩 38"之间。
由于本申请人对致动器即气体释放装置及可更换燃料盒进行了有效改 进， 气体释放阀 32"可以用市售的向上拔才放气的形式， 因而对降低打火机:； 制作成本很有贡献。
