具体实施方式
图1至图2示出了电动工具***100，其包括一种集尘器10和电动工具20，还包括用于连接电动工具20与集尘器10的连接夹持装置30。夹持装置30先连接至动力，并在紧固后连接集尘器10。其中，电动工具20可以是电锤，其能用于对墙体或墙面等进行钻孔或冲击作业，其在操作过程中会产生大量碎屑和粉尘等，严重影响用户体验和操作环境，严重的情 况下，还会影响用户操作，造成安全隐患。故设置一个可在电锤运行的同时能同步运行或独立运行的集尘器10。集尘器10具有吸附碎屑及粉尘的功能。夹持装置30包括握持部31、第一连接机构32和第二连接机构33。其中，第一连接机构32用于连接电锤或其他电动工具20；第二连接机构33用于连接集尘器10。电锤包括可用握持的把手部和可供连接夹持装置30的第三连接部21。作为其他可选的实施方式，集尘器10还可以连接其他可能会产生碎屑或粉尘的锤钻类工具或其他工具。
如图3所示，夹持装置30基本沿第一直线101方向延伸，第一连接机构32设置在握持部31和第二连接机构33之间。当第二连接机构33套设至电锤的第三连接部21时，可以通过旋转握持部31将夹持装置30拧紧至第三连接部21，此时，握持部31可以作为电锤的一个副把手供用户握持。进而将集尘器10安装至电锤上，通过将第二连接机构33卡接至吸尘机，并调整至合适位置，再完成紧固。
如图4至图5所示，第二连接机构33包括定位件331、限位组件332和紧固件333。第二连接机构33自夹持装置30的一端延伸出来，定位件331与夹持装置30固定连接或一体成型。定位件331呈“T”字型，其具有连接至夹持装置30的连接端331a和自连接端331a延伸出来的定位端331b。其中，连接端331a与第一直线101垂直或相交，定位端331b与第一直线101平行或倾斜相交。限位组件332包括第一限位件332a和第二限位件332b。其中，第一限位件332a与夹持装置30的主体固定连接或一体成型。第二限位件332b与夹持装置30的主体构成转动连接。第二限位件332b具有第一连接孔332c和第二连接孔332d，第一连接孔332c用于***一个转轴332f，从而可供第二限位件332b围绕转轴332f转动。第二连接孔332d可供紧固件333***，并形成有内螺纹结构332e，紧固件333形成有外螺纹结构333a，当紧固件333***第二连接孔332d后，能通过内螺纹结构332e与外螺纹结构333a的配合，将第二限位件332b紧固至第一限位件332a。第二连接机构33还包括与紧固件333配合的接触件336，接触件336与紧固件333接触的一面具有一个接触面336a，该接触面336a为一个球面，从而使得第二限位件332b通过紧固件333固定至第一限位件332a时，紧固件333由于与呈球面形成的接触面336a接触，这样使得紧固件333与球面上各个点的作用力均是垂直于接触面336a的。事实上，通过设置紧固件333与球面接触，实际上是实现了“点”与“面”接触，避免“面”与“面”接触，使得平面之间由于挤压、变形、倾斜等因素导致紧固件333与接触面336a直接的接触不牢固。通过上述设置，使得紧固件333与接触面336a之间的相互作用力更集中，从而使得第二限位件332b与第一限位件332a之间的夹持力更大，从而使得夹持装置30对集尘器10的夹持力更大，夹持更紧固。作为另一种实现方式，还可以将接 触面设置在紧固件上，并在操作紧固件时使得紧固件上的接触面与接触件接触以实现“点”与“面”的接触，从而增大接触件与紧固件之间的相互作用力。
此外，第二连接机构33还设置有第一弹性件335，第二连接机构33形成有用于容纳第一弹性件335的容纳腔334，第一弹性件335一端抵持容纳腔334内，一端抵持第二限位件332b，这样使得第一限位件332a和第二限位件332b之间始终保持较大的开口，从而能够快速夹持集尘器10。当紧固件333将第二限位件332b固定至第一限位件332a时，首先需要克服第一弹性件335的弹性力，从而再紧固第二限位件332b。事实上，第一限位件332a和第二限位件332b均形成有卡爪部332g，其能夹持集尘器10，并在紧固件333的作用下将集尘器10夹紧。集尘器10还包括与第二连接机构33配合的第四连接部117，第四连接部117还形成有与定位件331配合的定位孔，当集尘器10安装至第二连接机构33时，首先将定位件331***至定位孔中，并沿第一直线101方向移动集尘器10，从而能通过定位件331将集尘器10初步定位在第二连接机构33上，从而避免用户在规定集尘器10时，还需要再另外扶持集尘器10，有效的增加用户操作便利性。
如图6至图9所示，集尘器10包括壳体部11、进风通道12和集尘盒组件13，其中，壳体部11形成一个容纳空间111，进风通道12至少部分设置在壳体部11内，并形成有进风口121和出风口122。壳体部11内设置有能产生气流的风扇112，风扇112高速运转并能在壳体部11内形成负压，通过进风口121吸附碎屑及粉尘，在经过进风通道12的传送送出至集尘盒组件13，在经过集尘盒组件13过滤后，通过出风口122排出无尘气体。集尘器10还包括用于连接电源的结合部(图未示出)，结合部可以用于连接电池包等电源装置。在一些可选的实施方式中，结合部还可以连接电源线等。为清楚的说明本申请的技术方案，还定义了如图6所示的：前侧、后侧、左侧、右侧、上侧和下侧。集尘器10的集尘盒组件13连接至集尘器10的后侧。集尘器10包括一个可供碎屑和粉尘吹出的出尘口132，集尘盒组件13设置有一个与出尘口132配合的进尘口131。作为一种可选的实施方式，集尘器10的连接端331a采用嵌入式结构以连接集尘盒组件13，即集尘器10上至少部分形成有凹槽113，该凹槽113能容纳至少部分的集尘盒组件13，从而能够有效利用集尘器10壳体内部的空间。事实上，通过优化集尘器10内部的排线和结构设置，可以有效的增加凹槽113的体积，从而能够嵌入更多体积的吸尘盒组件。事实上，通过嵌入式的连接方式，吸尘盒组件本身的体积也能够增大。由于集尘器10与集尘盒组件13的连接位置采用嵌入式连接，集尘盒组件13能够做的更大、更长，且不占用连接空间。集尘器10内部还设置有用于控制集尘器10运动的控制面板114，控制面板114设置在壳体部11形成的容纳空间111内，并被设置在一个与沿前后方向 延伸的直线方向倾斜相交的平面内，以此进一步增加了壳体部11内部的空间利用率。
可选的，集尘盒组件13包括基座133、滤纸组件134和集尘盒135。其中，滤纸组件134安装在基座133上，基座133与集尘盒135连接并能构成一个可以容纳滤纸组件134的容纳腔。为方便将集尘盒组件13安装至集尘器10，集尘盒组件13上还设置有连接组件136。连接组件136包括用于将集尘盒组件13连接至集尘器10的第一连接件136a和用于将集尘盒135连接至基座133的第二连接件136b。其中，基座133上设置有沿第二直线方向延伸的转动轴，第一连接件136a为围绕转动轴转动的锁扣；第二连接件136b也为围绕转动轴转动的锁扣。当集尘盒组件13通过第一连接件136a固定至集尘器10上时，第二连接件136b无法被触发，此时集尘盒135无法被从集尘盒组件13上拆卸下来，从而能够避免用户误触碰连接组件136，导致集尘盒135内的灰尘倾覆出来，造成二次污染。仅当集尘盒组件13被从集尘器10上拆卸下来时，集尘盒135才能被从集尘盒组件13上拆卸下来，从而方便用户在预设位置或指定位置清灰，从而有效的控制了二次污染现象的产生。
如图10至图12所示，为实现上述功能，集尘器10的壳体部11上形成或连接有与第二连接件136b配合的第一止挡部115，第二连接件136b上形成或连接有与第一止挡部115配合的第二止挡部136c。当集尘盒组件13安装至集尘器10上时，第一止挡部115与第二止挡部136c抵触，第一止挡部115限制了第二连接件136b的转动，此时，第二连接件136b始终保持与集尘盒135的连接，从而集尘盒135无法从集尘盒组件13上拆卸下来。
如图13所示，滤纸组件134包括滤纸134a和固定件134b，滤纸134a通过固定件134b固定成一个整体，固定件134b形成有多个卡扣，并能与基座133构成卡扣连接。从而能够有效增加更换滤纸134a的便利性。固定件134b可以是一种塑料件，其具有强度高、质量轻的特点，并能便于成型，使得其能形成多个卡扣。事实上，滤纸134a存在有多片，其在自然状态下是分离状态，在安装至集尘盒组件13之前，需要将其固定成一个整体。通过设置塑料件，能够有效的固定滤纸134a，并能增强其作为一个整体的强度。事实上，通过这种设置方式，用户可以通过卡扣结构快速拆装滤纸134a，且不需要借助其他工具。
如图1和图14所示，集尘器10包括一个控制按钮116，控制按钮116能控制集尘器10在不同模式之间切换。示例性的，集尘器10包括触发模式和自动模式。在触发模式下，需要触发集尘器10的吸尘口至一个预设位置，从而启动集尘器10开始吸尘；当吸尘口未被触发且远离该预设位置时，集尘器10停止吸尘。在自动模式下，集尘器10可以始终保持吸尘状态。集尘器10的进风通道12包括：活动管123、导轨部124和弹性导管125。其中，活动管123能在导轨部124上自由滑动，在活动管123和出尘口132之间设置弹性导管125，弹性导 管125具有一个预紧力，其能抵持活动管123并将活动管123推送至距离出尘口132最远的位置。当操作电锤工作时，钻头等工件在钻入墙体中时，活动管123会偏压弹性导管125，并朝向出尘口132运动，此时活动管123会缩短暴露在集尘器10壳体部11外侧的长度，并进入至壳体部11内侧。
集尘器10的壳体部11上还设有一个非接触式开关126，非接触式开关126设置在活动管123的滑动路径上，并在活动管123滑动至预设位置时，能被触发。该非接触式开关126可以是一个霍尔开关或光电开关，其在被活动管123上的磁性件触发时，能传递一个电信号，从而连通电路以开启集尘器10的吸尘功能。
集尘器10具有以下操作方法：
当长按控制按钮116，控制电路进入触发模式；
此时集尘器10的霍尔开在未被触发时，集尘器10不启动吸尘功能；当活动管123被挤压且触发霍尔开关时，集尘器10启动吸尘功能；当所述活动管123远离所述霍尔非接触式开关126时，所述霍尔非接触式开关126传递另外一个电信号，所述电路被断开，所述集尘器10停止集尘；
当短按控制按钮116，控制电路能在触发模式和自动模式之间切换；
此时集尘器10能被控制进入触发模式或自动模式；当集尘器10处于触发模式时，则能以长按控制按钮116的方法控制集尘器10是否启动吸尘功能；当集尘器10处于自动模式时，则能保持始终处于吸尘状态；
当长按控制按钮116，使得控制电路处于切断状态；
此时，按照短按控制按钮116的操作，无论集尘器10处于何种模式下，均能在控制按钮116被长按后被关停。
