Description

一种导电伸缩管及手持式吸尘器
技术领域
本发明涉及一种手持式吸尘器，同时还涉及一种吸尘器的导电伸缩管。
背景技术
众所周知，手持式吸尘器其基本包括吸尘器主体、吸尘头（地刷）、以及将吸尘头与吸尘器主体相连通的吸尘管，其中吸尘管吸尘管内还设有导电组件，在吸尘器主体的控制下，通过导电组件将电力导向吸尘头，使得吸尘头开始工作。
然而，目前的吸尘管都是一整节的，且尺寸长度均大于吸尘器主体和吸尘头的长度或宽度，故从携带方面考虑，十分的不方便，因此，很难受到消费者的青睐；同时给销售时的包装带来极大的不便。
同时，为了克服上述的缺陷，部分厂家将吸尘管换成了伸缩的类型，然而，在实现伸缩过程中，其带来了很的缺陷，那就是导电组件的设置，必须使得导电组件能够随着吸尘管的伸缩而相对展开和收拢，因此导电组件的设计或结构就十分的复杂，再由，一旦出现使用意外，也不方便导电组件的维修（导电组件的内置）。
发明内容
本发明所要解决的技术问题是克服现有技术的不足，提供一种改进的导电伸缩管。
同时，本发明还提供一种改进的手持式吸尘器。
为解决上述技术问题，本发明采取如下技术方案：
一种导电伸缩管，其包括能够相对伸缩的多节套管、设置在每节套管上的能够相连通的导电组件，该导电组件包括沿着每节套管长度方向设置在套管一侧的安装座、沿着安装座长度方向设置的接触条、以及分别将每相邻两个接触条相导电连接的导电接头，其中每相邻的两个安装座之间伸缩设置，导电接头的两端部分别位于相邻的两个安装座内，且能够随着相邻两个安装座的伸缩运动始终将相邻两个接触条相导电连接。
优选地，在每节安装座的两侧设有沿其自身长度方向设置的安装槽，接触条包括分别设置在安装槽内的两条导电片，导电接头的两端部分别与相邻两个接触条的两个导电片相连通。
进一步的，两条导电片之间相平行设置，且分别为正极导电片和负极导电片，导电接头的端部位于正极导电片和负极导电片之间将正极导电片和负极导电片相连通。
根据本发明的一个具体实施和优选方面，相邻的两个安装座分别为第一安装座和第二安装座，相邻两个接触条分别为第一接触条和第二接触条，导电接头的一端部设置在第二安装座内并与第二接触条的正极导电片和负极导电片相导电连通；另一端部伸入第一安装座中与第一接触条的正极导电片和负极导电片相导电连通，当第一安装座和第二安装座相对伸缩时，导电接头的另一端部与第一接触条相对运动，且两者保持相接触设置。
优选地，导电组件还包括设置在导电接头的另一端部并趋向于两侧张开运动的弹性片，弹性片两侧抵触在第一接触条的正极导电片和负极导电片之间、并将第一接触条的正极导电片和负极导电片相导电连通。
根据本发明的又一个具体实施和优选方面，导电伸缩管还包括用于将相对伸缩调节后的两个套管相对锁定的锁定机构。
优选地，相邻的两个套管分别为第一管体和第二管体，锁定机构包括设置在第一管体上的锁定件、设置在第二管体上的锁合部、以及解锁件，其中当锁定机构锁定时，锁定件与锁合部锁合；当锁定机构解锁时，锁定件与锁合部分离。
进一步的，锁合部包括自第二管体表面向内凹陷形成的凹槽、设置在凹槽内的锁条，其中凹槽和锁条均沿着第二管体的长度方向延伸，且在锁条上设有多个锁槽，该多个锁槽沿着锁条的长度方向间隔分布。
更进一步的，锁定件包括固定在第一管体端部的锁座、活动设置在锁座内的锁销，解锁件包括自中部转动设置在锁座内的解锁按钮、以及设置在解锁按钮与锁座之间使得解锁按钮复位的复位件，其中锁销与复位件分别位于解锁按钮的两端，当按动解锁按钮时，复位件被压缩形变，锁销向锁座外运动、并与锁槽脱离，实现解锁；当按松开解锁按钮时，复位件恢复形变，锁销向锁座内运动、并插入锁槽内，实现锁定。
本发明采取另一个技术方案如下：
一种手持式吸尘器，其包括吸尘器本体、吸尘头、以及吸尘管，其中吸尘管为上述的导电伸缩管，该手持式吸尘器还包括分别设置在导电伸缩管的两端部、且分别与吸尘器本体和吸尘头相卡接的连接头；以及分别设置在连接头内的导电插接件，其中导电伸缩管分别与吸尘器本体和吸尘头卡接时，导电插接件分别与吸尘器本体和吸尘头的电路相连通。
由于以上技术方案的实施，本发明与现有技术相比具有如下优点：
本发明一方面将整根吸尘管变成了伸缩式，从而便于携带，同时也缩小了销售时包装的体积，给消费者留下良好的印象；另一方面由导电组件的外置以及能够随着导电伸缩管的伸缩运动始终将相邻两个接触条相导电连接，结构简单，设计巧妙，且维修和更换方便。

相邻的两个套管30分别为第一管体30a和第二管体30b，锁定机构32包括设置在第一管体30a上的锁定件320、设置在第二管体30b上的锁合部321、以及解锁件322，其中当锁定机构32锁定时，锁定件320与锁合部321锁合；当锁定机构32解锁时，锁定件320与锁合部321分离。
进一步的，锁合部321包括自第二管体30b表面向内凹陷形成的凹槽321a、设置在凹槽321a内的锁条321b，其中凹槽321a和锁条321b均沿着第二管体30b的长度方向延伸，且在锁条321b上设有多个锁槽b，该多个锁槽b沿着锁条321b的长度方向间隔分布。
更进一步的，锁定件320包括固定在第一管体30a端部的锁座320a、活动设置在锁座320a内的锁销320b，解锁件322包括自中部转动设置在锁座320a内的解锁按钮322a、以及设置在解锁按钮322a与锁座320a之间使得解锁按钮322a复位的复位件322b，其中锁销320b与复位件分别位于解锁按钮322a的两端，当按动解锁按钮322a时，复位件322b被压缩形变，锁销320b向锁座320a外运动、并与锁槽b脱离，实现解锁；当按松开解锁按钮322a时，复位件322b恢复形变，锁销320b向锁座320a内运动、并插入锁槽b内，实现锁定。
本例中，弹性片313、正极导电片和负极导电片的材质均为铜。
综上所述，本实施例具有以下优势：
1）、将整根吸尘管变成了伸缩式，从而便于携带，同时也缩小了销售时包装的体积，给消费者留下良好的印象。
2）、采用独特的锁定机构，将两根伸缩的第一管体和第二管体相对锁定，当按动解锁按钮时，复位件被压缩形变，锁销向锁座外运动、并与锁槽脱离，实现解锁；当按松开解锁按钮时，复位件恢复形变，锁销向锁座内运动、并插入锁槽内，实现自行锁定。整个过程操作简单，实施方便，且成本低。
3）、由导电组件的外置、以及能够随着导电伸缩管的伸缩运动始终将相邻两个接触条相导电连接，结构简单，设计巧妙，且维修更换方便。
4）、采用相对张开的弹性片，从而使得正极导电片和负极导电片时刻相连通，不易出现接触不良或断线的现象发生，确保吸尘器安全使用。
以上对本发明做了详尽的描述，其目的在于让熟悉此领域技术的人士能够了解本发明的内容并加以实施，并不能以此限制本发明的保护范围，凡根据本发明的精神实质所作的等效变化或修饰，都应涵盖在本发明的保护范围内。
