为了清楚的说明本申请的技术方案，还定义了如图1和图2，的上侧、下侧、左侧、右侧、前侧和后侧。
以下结合附图和具体实施例对申请作具体的介绍。
参照图1所示，本申请的第一实施例的吹尘风扇100，吹尘风扇100可以适用于室内和室外场所，主要针对粉尘或环境中颗粒物较多的场所进行除尘或降尘操作，同时还可以对环境进行降温。
吹尘风扇100包括主机1和直流电源。其中，直流电源可拆卸地连接至主机1以为主机1供电。直流电源为电池包，后续描述，将用电池包代替直流电源，但电池包并不能作为对本发明的限制。对于没有比较方便使用的市电的地方，带电池包的吹尘风扇100使用起来更为方便。
该吹尘风扇100为一种方便携带的吹尘风扇。当用户需要在户外进行工作时，用户可以携带吹尘风扇100至户外以提供吹尘和降温需求。本实施例的吹尘风扇100不同于家用降温风扇，家用降温风扇通常是被放置在干净环境下且相对位置变换较少。但是图1中的吹尘风扇100在使用时通常是放置在工况恶劣的工作区域进行工作。
吹尘风扇100可以通过电池包进行供电，因此即使是用户在户外工作且周围没有市电的情况时，也可以使用电池包对吹尘风扇100进行供电，从而方便使用。因此，该吹尘风扇100不同于相关技术中的仅能通过交流电进行供电的风扇，该吹尘风扇100也可以被称作直流吹尘风扇。在一实施例中，该吹尘风扇100也不限制于仅能使用电池包进行供电。如果该吹尘风扇100既可以用电池包进行供电也可以用使用交流电进行供电时，该吹尘风扇100也可以称为直流吹尘风扇。
如图1-2所示，主机1包括：支撑组件10、风扇组件13、过滤组件14和连接组件15。其中，支撑组件10用于支撑风扇组件13和过滤组件14。支撑组件10包括：底座11和机架12。底座11用于支撑整个吹尘风扇100以使吹尘风扇100被放置在工作面上。机架12与底座11连接，机架12至少部分设置在底座11的上方。机架12的一端与底座11连接，机架12的另一端与风扇组件13连接，从而机架12支撑风扇组件13。
风扇组件13包括：扇叶131、电机132和壳体。电机132用于驱动扇叶131绕电机轴线100a转动。扇叶131转动产生气流。风扇组件13包括用于进风的第一端13a和用于出风的第二端13b。在本实施例中，第一端13a位于风扇13的后端，电机132也安装在靠近第一端13a的一侧。在本实施例中，电机132为直流电机。在 一些实施例中，电机132为直流无刷电机。
在本实施例中，壳体包括：设置在第一端13a一侧的第一壳体133和设置在第二端13b一侧的第二壳体134。第一壳体133和第二壳体134形成一个包围扇叶131和电机132的腔体。在本实施例中，第一壳体133和第二壳体134分别与机架12连接。在其他可替换实施例中，第一壳体133与第二壳体134中的任意一个与机架12连接。第一壳体133至少包围在扇叶131的第一端13a的一侧。为使气流可以动，第一壳体133和第二壳体134为呈网状结构。
在本实施例中，电机132与第一壳体133连接。
如图2-3所示，过滤组件14包括：含有过滤材料的滤芯141。滤芯141可拆卸安装在风扇组件13的第一端13a的一侧。在风扇组件13的电机132启动后，扇叶131转动产生气流，气流从进风的第一端13a流动到出风的第二端13b。当过滤组件14安装在第一端13a的一侧后，气流经过过滤组件14后才会从第二端13b流出，使得风扇组件13吹出的风经过过滤后粉尘等大幅减少。吹尘风扇100利用风扇自身的进风机制将粉尘吸附，通过过滤组件14中的滤芯141将粉尘吸附过滤，对环境中的粉尘进行除尘过滤，避免扬尘。同时过滤组件14中的滤芯141也减少了粉尘进入风扇组件13，减少粉尘吸附在扇叶131和电机132上延长了工作寿命。充分利用现有环境中的机器，不增加新机器，减少对工作环境中可用面积的占用。当过滤组件14从被拆除时，吹尘风扇100既可以当做普通便携风扇使用。使用工况更多。
如图1-2所示，支撑组件10形成有用于可拆卸的结合电池包的结合部111。在本实施例中，第一电池包101可拆卸安装至底座11。在其它实施例中，第一电池包101也可以安装至机架12。在一实施例中，可以将吹尘风扇100中的扇叶131、驱动扇叶131转动的电机132和过滤组件14之外的所有零件认为是属于支撑组件10的一部分。例如壳体，也可以认为属于机架12。第一电池包101可以安装至支撑组件10中的任意一个零件上。
在本实施例中，支撑组件10的结合部111也能安装第二电池包102。第一电池包101具有第一体积和第一容量，第二电池包102具有第二体积和第二容量。第一体积大于第二体积，第一容量大于第二容量。结合部111内还设置有接入端子(图中未示出)，接入端子用于与第一电池包101或者第二电池包102电连接。用户可以根据需要选择将第一电池包101或者第二电池包102插入至结合部111。结合部111不仅能与第一电池包101匹配，也能与第二电池包102匹配。从而用户 可以根据需要安装具有不同体积或者不同容量的电池包，提高了吹尘风扇的适配能力，同时也延长了吹尘风扇100的使用时间。
在本实施例中，第一电池包101和第二电池包102具有相同的标称电压。第一电池包101的标称电压大于等于12V，第二电池包的标称电压大于等于12V。在一些实施例中，第一电池包101的标称电压大于等于18V，第二电池包102的标称电压大于等于18V。在一些实施例中，第一电池包101的标称电压大于等于40V，第二电池包102的标称电压大于等于40V。在一些实施例中，第一电池包101的标称电压小于等于80V，第二电池包102的标称电压小于等于80V。在一实施例中，第一电池包101的标称电压为10.8V、24V、36V、48V、56V或80V。第二电池包102的标称电压为10.8V、24V、36V、48V、56V或80V。使得第一电池包101或者第二电池包102的输出功率较大，而且第一电池包101或者第二电池包102的容量也较大，从而提高吹尘风扇100的工作时间以及工作效率。
在一实施例中，支撑组件10的结合部111还能适配第三电池包103，第三电池包103可以具有第三体积和第三容量，从而能进一步的提高吹尘风扇100的适配能力。
在本实施例中，第一电池包101的第一容量与第二电池包的第二容量的比值大于等于2。在一些实施例中，第一电池包101的第一容量与第二电池包的第二容量的比值大于2。或者，在其它实施例中，第一电池包101的第一容量与第二电池包的第二容量的比值大于等于3。
在本实施例中，第一电池包101的第一容量大于4.5Ah，这样可以提高第一电池包101的续航时间，进而提高吹尘风扇100的工作时长。其中，第一电池包101内可以包括第一电芯组和第二电芯组，第一电芯组内设置有多个电芯单元，多个电芯单元串联。第二电芯组内也可以设置多个电芯单元。第一电芯组和第二电芯组并联。也即是说，第一电池包101内设置有两组并联的电芯组。在其它实施例中，第一电池包101内也可以设置三组并联的电芯组，这样，可以进一步的提高第一电池包101的续航时间。第一电池包101的第一容量还可以大于等于5Ah。
在本实施例中，第一电池包101、第二电池包102和第三电池包103安装在吹尘风扇的结合部111时为电机132供电。电池包在脱离所述结合部111后用于为其他电动工具供电。在一实施例中，此电动工具包括手持式电动工具例如，电钻、电木铣、打磨机、打草机、修枝机、链锯。还包括台型电动工具例如，台锯、 斜锯。还包括手推式动力工具，例如，手推式割草机、手推式扫雪机。或者，还包括骑乘式动力工具，例如，骑乘式割草机、骑乘式车辆、全地形车等。或者，还可以是机器人工具，例如，割草机器人、扫雪机器人等。还包括照明工具。在吹尘风扇100所在的使用环境中同时使用的电动工具，提高吹尘风扇与其他电动工具的适配能力。
如图2-3所示，吹尘风扇100还包括风罩组件26，风罩组件26包括进风口261、出风口262和通道部263。其中，通道部263内部形成气流腔。扇叶131转动产生气流从进风口261进入通道部263形成的气流腔，再从出风口262流出风罩组件26。出风口262包覆于第一端13a上。在本实施例中，出风口262包围在第一壳体133外部，以使出风口262流出的气流基本全部进入风扇组件13。进而，扇叶131转动产生气流形成一条从进风口261流经通道部263再从出风口262进入第一端13a的流动风路，然后气流从过滤组件14从第二端13b离开吹尘风扇100。
其中，过滤组件14中的滤芯141至少部分设置在通道部263内。在本实施例中，设定过滤组件14中的滤芯141的在初始状态即未使用状态时的能够起到过滤作用的工作面为有效工作面，工作面的面积为有效工作面积。气流的流动风路与有效工作面相交，在相交处形成一相交面。在一实施例中，气流的流动风路与过滤组件14的有效工作面垂直。为保证过滤组件14中滤芯141可以尽可能将流动风路的气流过滤，有效工作面积大于等于相交面的面积。在本实施例中，有效工作面积大于等于过滤组件14安装处的通道部263的截面积。
在风罩组件26中，进风口261为气流进入风罩组件的入口，进风口261可以仅有一个也可以有多个，过滤组件24设置在进风口261和出风口262之间。为使除尘过滤装置的过滤效果更好，过滤组件14和第一端13a之间不设置进风口261。
如图3所示，风罩组件26上开设有安装槽264，过滤组件14可拆卸设置在安装槽264中。其中，在本实施例中，过滤组件14包括一个滤芯14。过滤组件还包括多个滤芯或多层过滤材料。在一些实施例中，过滤组件14还包括滤芯外壳或连接多个滤芯的连接部。
作为可替代的实施例，将通道部263包括连接第一端13a的第一通道2631和铰接在第一通道2631一端的第二通道2632。其中，进风口261设置在第二通道2632上，过滤组件14设置在第一通道2631和第二通道2632之间。在本实施例中，安装槽264形成于第一通道2631。在一些可替换实施例中，安装槽264连接于第一通道2631，或安装槽264形成或连接与第二通道2632。安装槽264的过风面设 为镂空结构，以使气流通过流畅。
在本实施例中，第二通道2632可拆卸连接于第一通道2631。第二通道2632整体呈喇叭型。第二通道2632的大直径开口端连接第一通道2631。在本实施例中，第二通道2632的大直径开口端覆盖安装槽264的一侧过风面。第二通道2632的小直径开口为风罩组件26的进风口261。沿气流流通路径设置由小至大的风口，可以使控制进风量，以使吹尘风扇的过滤更加彻底。过滤效果好。而设置第二通道2632可拆卸连接，以使操作者可以根据不同的使用工况选择不同的进风口尺寸，进而调节进风量。在一些情况下，可以不安装第二通道2632，以使安装槽264的一侧过风面直接作为进风口。
在一些可替换实施例中，第二通道2632旋转连接于第一通道2631。在第二通道2632与第一通道2631的相接处通过铰链结构构成旋转连接。为保证连接稳定性，还设置有锁定结构，用于保证第一通道2631和第二通道2632的稳定连接。铰链结构包括合页结构、销孔结构以及其他形式的铰接方式。
在本实施例中，滤芯141包括多层过滤层，每层采用不同材料形成分级过滤效果。在其他可替换实施例中，过滤材料可以为一种材料，滤芯141能达到过滤效果即可，其材料在此不做过多赘述。
吹尘风扇100还包括：操作组件17。操作组件17上包括调速旋钮171，用于调节风扇组件13吹出的风的风速大小。调速旋钮171上包括至少一个速度档位。位于调速旋钮171下方的操作组件17上包含能量显示按键172、指示灯173和充电接口174。在一种实施方式中，能量显示按键172既可用于显示与吹尘风扇相连的电池包的工作电量，又可用于显示与充电接口174相连的被充电的电子设备的充电电量。当操作者以不同的按下保持时间或不同的频次去按动能量显示按键172时，指示灯173示出不同装置的电量。
在一些实施例中，操作组件17包括显示部用于向用户进行反馈即信息提示。其中，显示部可以是例如声音提示器、液晶显示器(LCD)、发光二极管(LED)显示器，有机发光二极管(OLED)显示器，或有机电致发光(EL)显示器。通过额外设置输入部进行信息输入。
在一些实施例中，显示部被配置为触控板。以使显示部和信息输入合二为一。在其他可替换实施例中，信息输入也可以使用外部设备代替，例如智能手机、平板计算机、笔记本电脑等.
如图1和图5所示，为使吹尘风扇100可以适用更多的使用环境。在底座11连 接有连接组件15，连接组件15包括第一连接件151和第二连接件(图中未示出)。其中，第一连接件151安装在底座11的底部。第二连接件可拆卸连接在需要放置吹尘风扇100的工作面上。第一连接件151与第二连接件配合设置。在本实施例中，第一连接件151和第二连接件设置有相互锁定结构，使吹尘风扇100使用更多的使用角度和使用形式。
如图6所示，作为本申请的第二种实施例的吹尘风扇，第一种实施例的区别在于过滤组件的安装。
如图6所示，过滤组件24的滤芯为过滤片或过滤网结构。过滤组件24的滤芯直接吸附或连接在风扇组件13的第一端。以使过滤组件24的滤芯安装和更换方便。
如图7-10所示，作为本申请的第三种实施例的工具箱系统。
一种工具箱系统300，包括工具箱机构31、风扇组件32和过滤组件34。工具箱机构31包括多个可拆卸安装的工具箱。工具箱用于放置电动工具，如手持式电钻、电木铣、打磨机等。每个工具箱包括壳体，壳体设置有容纳腔311。风扇组件32放置在容纳腔311中。壳体的侧壁上开设有风口312，用于风扇组件32的气体流动。
工具箱机构31包括多个可拆卸堆叠的工具箱。在本实施例中，工具箱机构包括第一工具箱31a和第二工具箱31b，其中，第一工具箱31a和第二工具箱31b沿第二直线301方向堆叠。其中，第一工具箱31a的第一壳体310a上设置有沿第二直线301方向延伸的凹槽部316。第二工具箱31b的第二壳体310b上设置有沿第二直线301方向凸出表面的突起部315。当第一工具箱31a和第二工具箱31b在第二直线301方向彼此堆叠时，凹槽部316接收突起部315，并且第一工具箱31a和第二工具箱31b沿垂直于第二直线301方向的相对运动被限制。
在本实施例中，第一工具箱31a设置在第二直线301方向堆叠的下方。为方便移动除尘过滤装置，第一工具箱31a包括行走机构313和握持机构314，其中，行走机构313用于使工具箱机构31移动位置。行走机构313包括轮子。握持机构314用于在工具箱机构31移动位置时方便用户握持。
如图9-10所示，风扇组件32包括：扇叶321和电机322。电机322用于驱动扇叶321绕电机轴线300a转动。风扇组件32包括用于进风的第一端32a和用于出风的第二端32b。在本实施例中，第一端32a位于风扇组件32的后端，电机322也安装在靠近第一端32a的一侧。
过滤组件34包括含有过滤材料的滤芯，在一实施例中，滤芯包括多层过滤材料，每层采用不同材料形成分级过滤效果，在其他可替换实施例中，过滤材料可以为一种材料，过滤组件能达到过滤效果即可，滤芯的材料在此不做过多赘述。
过滤组件34可拆卸安装在容纳腔311内并至少覆盖部分风口312。在风扇组件32启动后，扇叶321转动产生气流，气流从风口312进入或流出容纳腔311，粉尘也随着气流从风口312进入容纳腔211，当风口312设置过滤组件34后，粉尘在进入或气流流出时，会被过滤组件34过滤，起到除尘的作用，充分利用工具箱。
在本实施例中，风口312设置在壳体的多个侧壁上，同时，风口312也设置多个。风扇组件32的第二端32b朝向风口312，在一实施例中，风扇组件32的第一端32a也朝向风口312，使得气流的流通更加顺畅。
如图9-10所示，风扇组件32还包括支撑组件，支撑组件连接风扇组件32和工具箱。其中，支撑组件包括底座323和关节部324。底座323连接工具箱的壳体的内侧。以风扇组件32安装在第二工具箱31b为例，方便说明。底座323设置有第一安装部。第二壳体310b的至少一个侧壁内侧设置有第二安装部，第二安装部与第一安装部可拆卸接合，当第一安装部与第二安装部连接时，底座323与第二壳体310b的相互运动被禁止，使安装更为稳定。在本实施例中，第一安装部与第二安装部为螺栓和螺纹孔的配合。第二壳体310b可以在多个侧壁设置多个第二安装部，用以适应更多的使用工况和场景。关节部324连接底座323和扇叶321。关节部324与扇叶321的连接包括关节部324直接与扇叶321连接，也包括关节部324与电机322直接连接，电机322与扇叶321连接，关节部324构成与扇叶321的间接连接。关节部324至少第一轴线为轴旋转，在一实施例中，关节部为球头转动连接，使扇叶321可以产生多个角度以适应多种使用环境。
支撑组件形成有用于可拆卸的结合电池包101的结合部，电池包101为电机322供电。在本实施例中，第一电池包101安装至底座323。在一实施例中，可以将风扇组件32中的扇叶321、驱动扇叶321转动的电机322和过滤组件34之外的所有零件认为是属于支撑组件的一部分，这样，第一电池包101可以安装至支撑组件中的任意一个零件上。同时电池包101也可以放置工具箱中，通过电连接为电机322供电。电池包101在脱离所述结合部后用于为其他电动工具供电。在一实施例中，此电动工具包括手持式电动工具，例如，电钻、电木铣、打磨机、打草机、修枝机、链锯。还包括台型电动工具，例如，台锯、斜锯。还包括手推 式动力工具，例如，手推式割草机、手推式扫雪机。或者，还包括骑乘式动力工具，例如，骑乘式割草机、骑乘式车辆、全地形车等。或者，还可以是机器人工具，例如，割草机器人、扫雪机器人等。还包括照明工具。在工具箱系统300所在的使用环境中同时使用的电动工具，提高工具箱系统300与其他电动工具的适配能力。
结合部也能放置第二电池包102。第一电池包101具有第一体积和第一容量，第二电池包102具有第二体积和第二容量。第一体积大于第二体积，第一容量大于第二容量。结合部内还设置有接入端子，接入端子用于与第一电池包101或者第二电池包102电连接。用户可以根据需要选择将第一电池包101或者第二电池包102插入至结合部。结合部不仅能与第一电池包101匹配，也能与第二电池包102匹配。从而，用户可以根据需要安装具有不同体积或者不同容量的电池包，提高了风扇组件32的适配能力，同时也延长了风扇组件32的使用时间。在本实施例中，第一电池包101和第二电池包102具有相同的标称电压。在本实施例中，第一电池包101和第二电池包102具有相同的标称电压。第一电池包101的标称电压大于等于12V，第二电池包的标称电压大于等于12V。在一些实施例中，第一电池包101的标称电压大于等于18V，第二电池包102的标称电压大于等于18V。在一些实施例中，第一电池包101的标称电压大于等于40V，第二电池包102的标称电压大于等于40V。在一些实施例中，第一电池包101的标称电压小于等于80V，第二电池包102的标称电压小于等于80V。在一实施例中，第一电池包101的标称电压为10.8V、24V、36V、48V、56V或80V。第二电池包102的标称电压为10.8V、24V、36V、48V、56V或80V。使得第一电池包101或者第二电池包102的输出功率较大，而且第一电池包101或者第二电池包102的容量也较大，从而提高风扇组件32的工作时间以及工作效率。
在一实施例中，支撑组件的结合部还能适配第三电池包103，第三电池包103可以具有第三体积和第三容量，从而能进一步的提高风扇组件32的适配能力。
风扇组件32还可以供用户调节风扇的转速的大小，这样用户可以根据环境中的温度来选择风速的大小。
