具体实施方式
以下通过特定的具体实例说明本申请的实施方式，本领域技术人员可由本说明书所揭露的内容轻易地了解本申请的其他优点与功效。本申请还可以通过另外不同的具体实施方式加以实施或应用，本说明书中的各项细节也可以基于 不同观点与应用，在没有背离本申请的精神下进行各种修饰或改变。
请参阅图1-21。需要说明的是，本实施例中所提供的图示仅以示意方式说明本申请的基本构想，遂图式中仅显示与本申请中有关的组件而非按照实际实施时的组件数目、形状及尺寸绘制，其实际实施时各组件的型态、数量及比例可为一种随意的改变，且其组件布局型态也可能更为复杂。
为了解决采用大风叶的吹风机无法满足高转速下提供高风速高风量的要求以及大风叶存在稳定性差、对动平衡要求高及工作噪音比较大问题，本申请提供一种吹风机，吹风机包括机壳和并列设置于机壳内至少两个电机风叶组件，每个电机风叶组件使用高转速电机匹配小风叶，同一吹风机的至少两个电机及风叶可同时运行，这不仅能够降低工作噪音，而且还满足高转速下高风速高风量的要求。
请参阅图1-7所示，本申请提供一种具有三个电机风叶组件122的吹风机，吹风机包括主机10、吹管20及吹嘴30。吹管20安装于主机10一侧，吹嘴30安装于吹管20的远离主机10的一端。
请参阅图1-7所示，主机10包括机壳13及设置于机壳13内的外涵道121及并列设置于外涵道121的三个电机风叶组件122，外涵道121及三个电机风叶组件122共同构成涵道组件12。
请参阅图1-3所示，机壳13设有进风端和出风端，气流从进风端进入机壳13内，经过加压后由吹风侧流出。在机壳13的进风端处设置有格栅状的风窗，气流通过风窗进入机壳13内，这样能够避免杂物进入机壳13内，以免杂物与风叶1221相接触，使得风叶1221能够平稳运行，保证吹风机运行时的安全，提高吹风机的可靠性。
具体地，机壳13包括第一机壳13a和第二机壳13b，第一机壳13a和第二机壳13b连接形成容纳腔，该容纳腔用于容置涵道组件12，涵道组件12位于进风端和出风端之间。为了使进风均匀，风窗包括第一风窗15a和第二风窗15b，分别相对设置于机壳13的相对两侧，其中，第一风窗15a设置于第一机壳13a上，第二风窗15b设置于第二机壳13b上。
请参阅图1-3所示，为了便于放置，吹风机还包括底座14，底座14设置于机壳13的底部，底座14与机壳13之间可通过螺栓连接的方式固定或者卡扣方式固定。
请参阅图1-3所示，机壳13的容纳腔内还设置有用于引导和约束气流的导风筒11，导风筒11位于进风端和外涵道121之间，且导风筒11套接于外涵道121的靠近进风端的一端。
请参阅图2和图3，导风筒11为喇叭状，导风筒11靠近进风端的一端开口较大，导风筒11靠近出风端的一端开口较小，也即导风筒11靠近进风端的一端的截面面积大于靠近出风端的一端的截面面积，从而便于气流进入外涵道121。
请参阅图2-6所示，外涵道121为圆筒状，外涵道121的外侧形成有插接部，在机壳13的内侧设置有与该插接部相匹配的插槽，安装时，插接部插入插槽，从而将外涵道121固定于机壳13的容纳腔内，这样不仅方便外涵道121的拆卸，也可起到限位作用。当然，也可以采用螺栓等其他方式将外涵道121固定在机壳13的容纳腔内。
请参阅图2-6所示，外涵道121内形成有用于安装电机风叶组件122的三个并列布置的安装腔(安装腔的个数与电机风叶组件122的个数相同)，每个电机风叶组件122安装于一安装腔内，也即三个电机风叶组件122安装于外涵道121内，三个电机风叶组件122呈正三角形等间距排列，三个电机风叶组件122的旋转轴线平行。在一可选实施例中，也可将外涵道121设置为由三个并列设置的圆管连接形成，每个圆管作为一个用于安装电机风叶组件122的安装腔。
请参阅图2-7所示，每个电机风叶组件122包括内涵道1222、风叶1221以及电机1223；内涵道1222例如可采用过盈配合的方式或者螺栓连接的方式固定外涵道121的安装腔内，电机1223安装于内涵道1222内，风叶1221装配于电机1223的输出轴上，电机1223驱动风叶1221绕电机1223的输出轴线转动，且风叶1221位于内涵道1222的靠近进风端的一端。本申请的吹风机由于 采用多电机1223和多风叶1221结构，因而电机1223和风叶1221可采用高转速电机与小风叶的组合，利用小风叶稳定性好，对动平衡要求较低、工作噪音小的特点，不仅能够保证吹风机在工作时低噪音而且可以多个电机1223及风叶1221同时运行来满足高转速下高风速高风量的要求。
本申请的吹风机中各电机风叶组件122的电机1223可独立工作，在实际运行中，可根据需求选择一个或者多个电机1223运行，以实现风力或风量的调节。
参阅图2-7所示，为了便于气体的流动，减少气流的流动路径，提高吹风机的出风效率，电机风叶组件122还包括导流锥1224，导流锥1224安装于内涵道1222的靠近出风端的一端，内涵道1222与导流锥1224之间例如为卡扣连接，两者形成一个封闭结构。
请参阅图2-6所示，涵道组件12还包括固定座123，固定座123为圆筒状，固定座123嵌套于外涵道121的靠近进风端的一端，三个电机风叶组件122通过固定座123安装固定于外涵道121内。固定座123的底部开设有三个开孔，每个开孔与外涵道121的一安装腔同轴设置，每个开孔与一电机风叶组件122的内涵道1222连通，从而便于气流经内涵道1222从该开孔流出。当然，在一些实施例中，涵道组件12也可以不设置固定座123。
吹风机进行工作时，可以控制至少一个电机1223带动对应的风叶1221工作，外部空气依次经进风端进入导风筒11，通过风叶1221的加速增压，经吹管20并从吹嘴30处吹出。
请参阅图1-3，吹管20大体为圆管状结构，吹管20的管腔作为导风通道，吹管20的一端与机壳13的出风端通过卡扣连接，吹管20的另一端与吹嘴30连接，由三个电机风叶组件122的内涵道1222出来的气流汇合后经吹管20由吹嘴30吹出。
图1-3中的吹管20由于只有一个导风通道，三个电机风叶组件122产生的风经过吹管20时会相互影响，这会影响吹风机的风机效率。为此，本申请针对采用三个电机风叶组件122的吹风机的吹管20和吹嘴30进行了相应的改进，其中，图8示出了改进后的吹管20和吹嘴30的爆炸图、图9示出了图8所示 的吹嘴的立体结构示意图。
请参阅图8及图9，吹管20由三个并列设置的管体21连接形成，每个管体21的管腔作为一导风通道，导风通道沿管体21的轴向贯通设置，也就是说，吹管20具有三个并列设置的导风通道，三个导风通道之间相互隔开，互不影响。作为示例，管体21可为圆管或者锥形管。
可类似图10-图12所示，将外涵道121设置为由三个并列设置的圆管连接形成，每个圆管作为一个用于安装电机风叶组件122的安装腔；将导风筒11设置为由三个并列设置喇叭状管对接形成，导风筒11的一端套设于外涵道121的远离吹管20的一端。吹管20装配于外涵道121的远离导风筒11的一端，每个导风通道与一电机风叶组件122的内涵道1222连通，从而每个电机风叶组件122产生的风会经不同的导风通道流动并由吹管30的吹风口吹出，不会相互影响，能够提高吹风机效率。当然，也可将吹管20设置为一个圆柱状，内设三个导风通道，每个导风通道平行于吹管20的轴向设置，同时保证当吹管20装配于外涵道121的远离导风筒11的一端时，每个导风通道与一电机风叶组件122的内涵道1222连通。
请参阅图8及图9，吹嘴30用于控制吹风机的出风口32处的气流，吹嘴30大体为锥形管，吹嘴30具有连接端及与连接端31相对设置的吹风口32，吹嘴30的外轮廓由连接端向吹风口的一端逐渐收缩。吹嘴30的连接端的形状与吹管20的远离外涵道121的一端的形状相匹配，吹嘴30的连接端套设于吹管20的远离外涵道121的一端，吹嘴30设计为将三个导风通道吹出的风汇聚后经吹风口32吹出。吹嘴30的连接端31上开设有三个进风口31，每个进风口31与吹管20的一个导风通道连通，三个进风口131经吹嘴30的内腔与吹风口32连通，吹风口32为圆形或者其他合适的形状。每个电机风叶组件122产生的风会经不同的导风通道流动至吹管30，并经吹管30汇聚后从吹风口32。
当然，吹嘴30的吹风口32也可以被分隔成三个独立的子吹风口，每个子吹风口与一进风口31连通，从而每个电机风叶组件122产生的风会经不同的导风通道流动至吹管30，并经由并经由吹嘴30汇聚后经由不同的子吹风口吹出。
图10-12示出了具有两个电机风叶组件122的吹风机，为了简化，图10及图11中只示出了导风筒11、涵道组件12、吹管20及吹嘴30，而未示出机壳13、风窗、底座14等结构。
请参阅图10-12，涵道组件12同样也包括外涵道121以及设置于外涵道121内的两个电机风叶组件122。外涵道121由两个并列设置的圆管连接形成，每个圆管作为一个用于安装电机风叶组件122的安装腔。在一可选实施例中，也可将涵道组件12设置为一个圆筒状，内设两个安装腔，每个电机风叶组件122安装于一安装腔内。
电机风叶组件122也是由内涵道1222、电机1223、风叶1221及导流锥1224构成，内涵道1222例如可采用过盈配合的方式或者螺栓连接的方式固定外涵道121的安装腔内，电机1223安装于内涵道1222内，风叶1221装配于电机1223的输出轴上，且风叶1221位于内涵道1222的靠近进风端的一端，导流锥1224安装于内涵道1222的靠近出风端的一端，内涵道1222与导流锥1224之间例如为卡扣连接。详见上文描述。
请参阅图10-12，导风筒11是由两个并列设置喇叭状管对接形成，导风筒11的一端套设于外涵道121的远离吹管20的一端。
请参阅图10-13，吹管20的一端装配于外涵道121的远离导风筒11的一端，另一端与吹嘴30连接；吹管20由两个并列设置的管体21连接形成，每个管体21的管腔作为一导风通道，导风通道沿管体21的轴向贯通设置，也就是说，吹管20具有两个并列的导风通道，两个导风通道之间相互隔开，互不影响，每个导风通道与一电机风叶组件122的内涵道1222连通，从而两个电机风叶组件122产生的风不会相互影响，能够提高吹风机效率。作为示例，管体21可为圆管或者锥形管。
请参阅图10-图15所示，吹嘴30用于控制吹风机的出风口32处的气流，吹嘴30具有连接端及与连接端31相对设置的吹风口32。吹嘴30的连接端的形状与吹管20的远离外涵道121的一端的形状相匹配，吹嘴30的连接端套设于吹管20的远离外涵道121的一端，吹嘴30设计为将两个导风通道吹出的风 汇聚后经吹风口32吹出。
请参阅图10-图15所示，吹嘴30的连接端31上开设有两个进风口31，每个进风口31与吹管20的一个导风通道连通，两个进风口131经吹嘴30的内腔与吹风口32连通，出风口30为长圆孔(也称为腰型孔)。每个电机风叶组件122产生的风会经不同的导风通道流动至吹管30，并经吹管30汇聚后从吹风口32。
当然，吹嘴30的出风口32的形状也可以是其他形状，吹嘴30的出风口32例如也可以采用如图16及图17所示的由两个半径相等的优弧的端点对接后形成的图形，或者如图18及图19所示的圆形。其中，优弧定义大于半圆的弧或者圆心角大于180°的弧。
在一可选实施例中，吹嘴30的出风口32的形状也可以是如图20及图21所示的由两个半径相等的优弧的端点对接后形成的图形，并且吹风口32通过隔板33分割成两个独立的子吹风口，隔板33位于两个优弧的对接处，隔板33从吹嘴30的连接端延伸至吹风口31处，每个子吹风口与一导风通道连通，从而每个电机风叶组件122产生的风会经不同的导风通道流动至吹管30，并经由吹嘴30汇聚后经由不同的子吹风口吹出。当然，图14及图15、图16及图17、图18及图19所示的吹嘴30的出风口32也可通过隔板分隔成两个独立的子吹风口。
可以理解的是，在其他实施例中，吹风机也可以包括四个或四个以上电机风叶组件122，相应的，吹管20与吹嘴30的形状也要适应性的改变。
综上，本申请的吹风机包括至少两个电机风叶组件，每个电机风叶组件使用高转速电机匹配小风叶，同一吹风机的至少两个电机及风叶可同时运行，这不仅能够降低工作噪音，而且还满足高转速下高风速高风量的要求。本申请的吹风机在使用过程中可根据需求选择一个或者多个电机运行，以实现风力或风量的调节。
