一种带静电释放功能的无线吸尘器及其静电释放方法 技术领域
本发明涉及吸尘器领域，特别是涉及一种带静电释放功能的无线吸尘器及其静电释放方法。
背景技术
吸尘器在使用过程中，灰尘高速进入吸尘器，在尘杯中与塑料结构发生摩擦，使得电荷大量转移，同时吸入的灰尘与刷头、伸缩壁管摩擦引起电荷重新分布，使用者在静电积聚过多时使用，通常会由于手指等接触导致尖端放电，放电能量很小但是电压很高，温度极高，由此会出现打手现象。
目前，针对为了去除上述静电，通常是从吸尘部将静电引出至吸尘器手柄处，再利用适当的装置从吸尘器手柄引出至大地。现有技术中也存在防静电吸尘器风道，可以包括至少部分裸露在外且与金伸管和钢丝软管均电导通的钢片，其理论上可以实现消除静电，但是由于钢片与人体接触面积比较小，用户实际使用的时候，钢片与人体接触效果并不好，静电现象仍然存在。

所述无线吸尘器在使用过程中经由人体释放产生的静电。
本发明的方案，由于吸尘器主体处的静电是经由传输管传导至手柄处的，传输管不仅属于静电发生部件，还作为静电传导通道，即传输管是作为静电传导电路中的一部分，由此不需要额外设置导电线路或其它用来将静电由吸尘器主体传导至手柄的传导部件，不仅节约了成本，而且简化了结构。此外，通过设置与电传导件相对应的卡接件，使得简单地通过在外界作用力例如按压作用下即可将电传导件卡接在卡接件处，可以根据需要在吸尘器主体和/或手柄的多个位置处布置卡接件，以实现根据需要在合适的位置卡接电传导件，由此实现了电传导件数量的灵活设置，以及电传导件位置的灵活变化。又由 于手柄处可以设置电传导件，因此，手柄的材料选择性较为灵活，可以不限于金属材料，而是可以选择任意材料，以满足手柄的美观、牢固等外观配置。
此外，本发明的方案，静电既能够通过使用者接触手柄进行释放，又能够在吸尘器充电时通过静电释放电路进行释放，由此通过两者配合使用，能够将静电完全去除，避免由于静电放电而导致的线路板芯片的损坏，同时防止在使用无线吸尘器的过程中由于静电累积而引起的触电，极大提高用户体验。通过大量实验验证，本发明的静电释放电路中的电阻值大于7兆欧，电功率大于1/2瓦特时，既能够完全释放剩余静电荷，又能够避免触电。
根据下文结合附图对本发明具体实施例的详细描述，本领域技术人员将会更加明了本发明的上述以及其他目的、优点和特征。

具体实施方式
下面将通过具体实施方式对本发明的技术方案进行清楚、完整地描述。显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。 基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
图1示出了根据本发明一个实施例的带静电释放功能的无线吸尘器100的示意性剖视图。图3示出了根据本发明一个实施例的吸尘器在充电时释放静电荷的静电荷流动路径的示意图。参照图1或图3，本发明实施中，该无线吸尘器100为立式吸尘器100，其一般性可以包括传输管130、吸尘器主体120、吸入口体140和手柄110。该传输管130构成用于将吸入口体140吸引的空气供给到吸尘器主体120中的供给通路。该立式吸尘器100的吸尘器主体120和手柄110与该传输管130相连，并由该传输管130支撑。该吸尘器主体120可以包括电机121和集尘器。其中，该电机121经由吸入口体140、传输管130和集尘器来抽吸空气，该集尘器将该尘气中所含有的灰尘进行离心分离，该集尘器可以具有集尘室和集尘容器122。在吸尘器100工作时，设置在该吸尘器主体120内电机121被驱动，通过吸入口体140的空气吸入口来抽吸空气，该空气经过传输管130被输送至集尘器，在集尘器中，灰尘在集尘室中被离心分离，并被收集在集尘容器122中。在此过程中，除了吸尘器100的构成零件之外，被吸尘器100抽吸的空气中的灰尘也在例如集尘容器122、电机121或传输管130内表面发生摩擦而带上静电。
为了去除上述静电，本发明提供的带静电释放功能的无线吸尘器可以包括至少一个第一电传导件210和至少一个第二电传导件220。该至少一个第一电传导件210与该传输管130之间成电连接，以使得在吸尘器主体120的至少一个部位处的静电能够经由所述至少一个第一电传导件210传导至所述传输管130。该至少一个第二电传导件220设置在该手柄110处，其与该传输管130之间成电连接，以使得在传输管130处产生的静电和/或传导至所述传输管130处的静电能够从该传输管130传导至第二电传导件220。其中，在工作时，当使用者的人体接触该第二电传导件220时，传导至该第二电传导件220的静电经由人体进行释放。
在图1所示的实施例中，该无线吸尘器100包括五个第一电传导件210，其分别设置在集尘容器122和电机121处。在一个实施例中，五个第一电传导件210可以通过一个第一导电元件电连接，该第一导电元件电连接于传输管130处。在另一实施例中，五个第一电传导件210可以通过五个第一导电元件电连接，每一第一导电元件电连接于传输管130处。在图1所示的实施 例中，在集尘容器122处设置有两个第一电传导件210，该两个第一电传导件210之间通过一个第一导电元件电连接，该第一导电元件电连接于传输管130处。在电机121处设置有三个第一电传导件210，该三个第一电传导件210中的每一个相应地电连接一个第一导电元件，任一第一导电元件电连接于传输管130处。其中，该第一导电元件的材料选自能够导电的硬质材料和/或软质材料。硬质材料可以为金属片、金属条、非金属导电硬质材料等。软质材料为可以弯折且导电的材料，例如可以是导线、铁丝、铜丝等。
使用者可以根据需要灵活安装第一电传导件210，包括灵活布置第一电传导件210的位置以及第一电传导件210的数量，在一个实施例中，可以在吸尘器100主体处预先布置好第一卡接件和第一导电元件。每一第一卡接件与一个第一电传导件210相对应，第一电传导件210可以在外界作用力例如按压的作用力下卡接在该第一卡接件处，第一卡接件的材料选择成导电材料例如金属材料，以将第一电传导件210处的静电传导至第一卡接件处。同时，第一卡接件与第一导电元件电连接，且第一导电元件电连接于传输管130处，以使得第一卡接件处的静电通过第一导电元件传导至传输管130。可以按照发生静电的难易程度在吸尘器主体120的不同位置预先布置第一卡接件，例如，在吸尘器主体120最容易发生静电的多个位置处预先布置多个第一卡接件和相应的第一导电元件。可以在吸尘器主体120的可以卡接第一电传导件210的位置处对该位置容易发生静电的级别进行标注，使用者或者安装者可以根据实际需要在不同的位置处卡接第一电传导件210。
在图1所示的实施例中，该无线吸尘器100还包括设置在手柄110处的两个第二电传导件220，在一个实施例中，该两个第二电传导件220可以通过一个第二导电元件电连接，该第二导电元件电连接于传输管130处。在另一实施例中，该两个第二电传导件220可以分别通过两个第二导电元件电连接，该两个第二导电元件连接于传输管130。其中，该第二导电元件的材料选自能够导电的硬质材料和/或软质材料。硬质材料可以为金属片、金属条、非金属导电硬质材料等。软质材料为可以弯折且导电的材料，例如可以是导线、铁丝、铜丝等。
同样，为了增大第二电传导件220与使用者的手掌或手指的接触面积，在一个实施例中，可以在手柄110处预先布置多个第二卡接件和与第二卡接件对应的第二导电元件。可以理解的是，第二卡接件的数量并没有限制，也 可以布置一个第二卡接件。第二电传导件220可以在外界作用力例如按压的作用力下卡接在该第二卡接件处，第二卡接件的材料选择成导电材料例如金属材料，以使得来自吸尘器主体120处的静电经由传输管130，再通过第二导电元件传导至第二卡接件处，再通过与该第二卡接件电连接的第二电传导件220传导至使用者，最终使得静电通过使用者导出至大地。
图2示出了根据本发明一个实施例的吸尘器100在使用时释放静电荷的静电荷流动路径的示意图。如图2所示，吸尘器100工作时，来自吸入口体140和吸尘器主体120处的静电经由传输管130传导至手柄110，由于使用者的手指与手柄110相接触，静电又通过使用者传导至大地。
本发明的方案，由于吸尘器主体120处的静电是经由传输管130传导至手柄110处的，传输管130不仅属于静电发生部件，还作为静电传导通道，即传输管130是作为静电传导电路中的一部分，由此不需要额外设置导电线路或其它用来将静电由吸尘器主体120传导至手柄110的传导部件，不仅节约了成本，而且简化了结构。此外，通过设置与电传导件相对应的卡接件，使得简单地通过在外界作用力例如按压作用下即可将电传导件卡接在卡接件处，可以根据需要在吸尘器主体120和/或手柄110的多个位置处布置卡接件，以实现根据需要在合适的位置卡接电传导件，由此实现了电传导件数量的灵活设置，以及电传导件位置的灵活变化。又由于手柄110处可以设置电传导件，因此，手柄110的材料选择性较为灵活，可以不限于金属材料，而是可以选择任意材料，以满足手柄110的美观、牢固等外观配置。
图3示出了根据本发明一个实施例的吸尘器100在充电时释放静电荷的静电荷流动路径的示意图，图中L和N分别表示火线和零线。图4示出了根据本发明一个实施例的具有静电释放电路230的充电座150的示意性结构图，其中示出了静电释放电路230的大体位置。如图3和图4所示，为了释放静电荷，或者为了将使用过程中没有释放完全的静电荷释放完全，本发明的无线吸尘器100还可以包括与充电座150处的充电片151电连接的静电释放电路230。首先，需要理解的是，吸尘器100还可以包括充电座150和设置在吸尘器100整机并与该充电座150相配合的导电插片，该导电插片与吸尘器主体120或传输管130电连接，用于与充电座150处的充电片151相抵触，以对该吸尘器100进行充电。同时，可以理解的是，如图3所示，吸尘器100在使用过程中累积的未释放完的静电荷可以通过导电插片传导至充电片151 处，再通过充电片151传导至静电释放电路230，并通过静电释放电路230连接电网，从而释放静电。
静电释放电路230包括至少两个放电电阻器，其中，每一放电电阻器的电阻值大于7兆欧，且电功率大于1/2瓦特。图5示出了根据本发明一个实施例的静电释放电路230的电路图。如图5所示，静电释放电路230包括串联在交流电源的火线上的第一放电电阻器231和第二放电电阻器232。通过该第一放电电阻器231和/或第二放电电阻器232释放静电荷的工作原理为：静电荷通过充电片151传导至静电释放电路230，在该静电释放电路230中经由该第一放电电阻器231和/或第二放电电阻器232释放至电网，并通过电网传导至大地。图6示出了根据本发明另一个实施例的静电释放电路230的电路图。如图6所示，静电释放电路230包括串联在交流电源的火线上的第一放电电阻器231和第二放电电阻器232，还包括第一电容器233和第二电容器234，该第一电容器233与该第一放电电阻器231并联连接，该第二电容器234与该第二放电电阻器232并联连接。图7示出了根据本发明另一个实施例的静电释放电路230的电路图。图7所示出的实施例中，静电释放电路230包括串联在交流电源的火线上的第一放电电阻器231和第二放电电阻器232，还包括第三电容器235，该第三电容器235并联地连接在由第一放电电阻器231和所述放电电阻器构成的串联电路处。在本发明其他实施例中，第一放电电阻器231和第二放电电阻器232还可以串联在交流电源的零线上。
本发明的方案，静电既能够通过使用者接触手柄110进行释放，又能够在吸尘器100充电时通过静电释放电路230进行释放，由此通过两者配合使用，能够将静电完全去除，避免由于静电放电而导致的线路板芯片的损坏，同时防止在使用无线吸尘器100的过程中由于静电累积而引起的触电，极大提高用户体验。通过大量实验验证，本发明的静电释放电路230中的电阻值大于7兆欧，电功率大于1/2瓦特时，既能够完全释放剩余静电荷，又能够避免触电。
特别地，本发明一个实施例还提供了一种上述的带静电释放功能的无线吸尘器的静电释放方法，包括如下步骤：
S100、将无线吸尘器在使用过程中产生的静电经由人体进行释放；
S200、将步骤S100中未释放完的静电经由静电释放电路进行释放。
可以理解的是，在另一实施例中，使用过程中产生的静电可以不使用本 发明中通过人体释放的方法。未通过人体释放的静电经由静电释放电路进行释放。
至此，本领域技术人员应认识到，虽然本文已详尽示出和描述了本发明的多个示例性实施例，但是，在不脱离本发明精神和范围的情况下，仍可根据本发明公开的内容直接确定或推导出符合本发明原理的许多其他变型或修改。因此，本发明的范围应被理解和认定为覆盖了所有这些其他变型或修改。
