具体实施方式
下面详细描述本发明的实施例，所述实施例的示例在附图中示出。下面通过参考附图描述的实施例是示例性的，旨在用于解释本发明，而不能理解为对本发明的限制。
下面结合附图1至图7具体描述根据本发明实施例的无叶风扇100。
如图1所示，根据本发明实施例的无叶风扇100包括外壳1、机头2、三通管3和动力系统4。
具体而言，外壳1内限定有容纳腔，外壳1上设有多个间隔开布置且与容纳腔导通的进风孔13，外壳1内具有出风口142，三通管3设在所述容纳腔内，三通管3具有相互连通的第一接口31、第二接口32和第三接口33，第三接口33与出风口142连通，动力系统4设在容纳腔内以产生高压气流，机头2设在所述外壳1上，机头2内限定有气流通道且机头2的两端分别与第一接口31和第二接口32连通，机头2具有与气流通道导通的排风口。
换言之，如图1所示，根据本发明实施例的无叶风扇100主要由外壳1、机头2、三通管3和动力系统4组成，其中，外壳1限定有容纳腔，并且在外壳1上设有多个进风孔13，每个进风孔13与容纳腔连通，外壳1内有出风口142。
机头2设在外壳1上，机头2限定有气流通道，并且具有相连通的两个端口和与气流通道相导通的排风口，机头2的两个端口与外壳1的出风口142导通，动力系统4设在容纳腔内，用来产生高压气流，三通管3也设在容纳腔内且邻近出风口142设置，具体地，三通管3具有相互连通的三个接口，其中一个接口与出风口142连通，另外两个接口与机头2的两 端连通，气流在动力系统4的作用下形成高压气流，并通过出风口142及三通的一个接口，经由三通管3的另外两个接口的导向作用、进入机头2的气流通道，最后从排风口喷出，带动周围气流运动循环，让使用者感觉有冷却效果。
由此，根据本发明实施例的无叶风扇100，通过在外壳1内的出风口142处设置三通管3，并将三通管3的两个接口分别与机头2的两端连通，使得由外壳1上的进风孔13进入的气流，在动力系统4的作用下形成高压气流，并通过三通管3的另外两个接口分流进入机头2的气流通道内，最终从机头2的排风口排出，大大地提高了无叶风扇100在单位时间内的出风量，给用户带来凉爽、舒适的体验。该无叶风扇100的结构简单，各部件连接可靠，装拆容易，气流运动循环分布均匀，各部件清洁便利，无需拆卸清洗，并且使用者不会触摸到内部部件，使用过程中放心安全，用户体验好。
其中，根据本发明的一个实施例，外壳1具有两个相对设置的安装口，机头2的两端分别与外壳1相连以封闭安装口。具体地，参照图1，外壳1上设有两个安装口，两个安装口对称设置，与机头2的两个端口相对应，可以实现与机头2两端对应连接，并且安装口与机头2的端口正好吻合，二者相连可以使安装口完全封闭，防止流经此处的气流向外泄漏。
具体地，外壳1包括基座12和外壳本体11，基座12形成柱状，基座12的侧壁设有多个进风孔13，外壳本体11设在基座12的上方且与基座12相连，外壳本体11形成球状，三通管3与外壳本体11卡接相连。
也就是说，外壳1主要由基座12和外壳本体11两部分构成，其中，基座12形状为沿竖直方向(如图1所示的上下方向)延伸的柱形，基座12放置在水平承载面上，可以对基座12以上部件起支撑作用，进一步地，基座12的侧壁上设有多个进风孔13，多个进风孔13之间相对间隔布置，气流可以通过进风孔13进入容纳腔内，外壳本体11设在基座12上面，并且与基座12相固定连接，外壳本体11呈球状，合理利用有效空间，而且外形美观。三通管3设在容纳腔内且与外壳本体11的内壁卡接相连，保证三通管3与外壳1的连接可靠性，并且省去了多余的装配连接件，既可以降低了成本，又可以提高装配效率。
进一步地，三通管3包括竖直管段和两个弧形管段。具体而言，竖直管段的一端形成第三接口33，两个弧形管段的一端相互连通且分别与竖直管段的另一端连通，两个弧形管段的另一端分别形成第一接口31和第二接口32，其中，三通管3的两个弧形管段可以分别与外壳本体11卡接连接，保证连接可靠性。由此，通过在外壳本体11内设置三通管3，不仅可以对各部件起到了连接作用，而且对经过三通管3的高压气流起到了分配导向作用，从而提高无叶风扇100在单位时间内的出风量。
优选地，两个弧形管段关于竖直管段的中心轴线对称布置，两个弧形管段的至少一部分与外壳本体11的弯曲弧度一致。换言之，两个弧形管段处于竖直管段的两侧，并且以竖直 管段的中心轴线为对称轴，在竖直管段两侧呈对称设置，此外，外壳本体11形成球状，三通管3的两个弧形管段的一部分与外壳本体11的弯曲弧度一致，两个弧形管段与外壳本体11的球状相互配合，合理利用了外壳本体11内的有效空间。
有利地，三通管3的朝向外壳本体11的一侧设有安装板5，安装板5与外壳本体11卡接相连。参照图3和图4，三通管3的上侧设有沿水平方向延伸的安装板5，安装板5与三通管3的弧形管段固定连接，然后将安装板5卡接在外壳本体11的内壁上，实现了三通管3与外壳本体11的固定连接。由此，通过在外壳本体11上设置有安装板5，既可以实现三通管3与外壳本体11的固定连接，避免三通管3于外壳本体11之间发生相对移动，又可以省去多余的装配连接件，简化三通管3的结构。
其中，根据本发明的一个实施例，安装板5上设有多个间隔开布置的定位孔，外壳本体11的内壁设有多个与定位孔配合的定位柱。具体地，如图3和图4所示，安装板5上设有多个定位孔，多个定位孔之间间隔布置，外壳本体11的内壁上设有多个定位柱，定位柱与定位孔相对应。三通管3与外壳1装配时，首先将三通管3上的安装板5正对外壳本体11的内壁，然后将外壳本体11的内壁上的多个定位柱插接在三通管3上的安装板5的多个定位孔内，实现二者的安装定位，防止安装板5与外壳本体11发生相对移动。
优选地，安装板5上设有多个间隔开布置的卡孔，外壳本体11的内壁设有多个与卡孔卡接相连的卡钩。由此，通过在安装板5上设置多个卡孔，并在外壳本体11的内壁设置与卡孔配合的卡钩，可以实现外壳本体11与安装板5的固定，防止安装板5相对外壳本体11上下滑动，保证三通管3与外壳本体11的稳定连接，并且省去了多余的装配连接件，既降低了材料成本，又简化了装配工序，提高无叶风扇100的生产效率。
可选地，根据本发明的一个实施例，机头2形成倒置的U形，机头2具有第一进口端和第二进口端，第一进口端和第二进口端的开口分别形成圆形。参照图1和图2，机头2为倒置的U形，形状美观，机头2具有两个端口，即第一进口端与第二进口端，两个端口的形状都为圆形，气流通过两个端口进入机头2的气流通道，两个端口的气流流量相同，机头2的两个端口分别与外壳本体11的安装口配合，使外壳本体11与两个端口装配后形成一个完整的球状，外观新颖、美观，给人以视觉享受。
其中，三通管3与机头2卡接相连，第一接口31和第二接口32的形状分别与第一进口端和第二进口端的开口形状一致。例如，在本实施例中，三通管3的第一接口31和第二接口32均形成圆形，外壳本体11的两个安装口分别形成圆形，而机头2的两端端口也分别形成圆形，三通管3的两个接口分别与机头2的两个端口卡接相连，既可以实现二者的固定连接，避免发生相对移动，又可以保证结构的密封性，提升无叶风扇100的外形美观。
在本发明的一些具体实施方式中，无叶风扇100还包括底座14，底座14设在容纳腔内 且位于三通管3的下方，底座14内限定有安装腔，底座14具有与安装腔导通的进风口141和出风口142，进风口141与多个进风孔13导通。
换言之，无叶风扇100主要由外壳1、机头2、三通管3、动力系统4和底座14组成，底座14设在外壳1的容纳腔内，底座14处于三通管3的下方且与三通管3相连，底座14内限定安装腔，底座14的下端和上端分别设有进风口141和出风口142，且进风口141与出风口142与安装腔相导通，进风口141与外壳1上多个进风孔13相连通，出风口142与机头2的气流通道导通，外界环境的气流依次通过多个进风孔13、底座14的进风口141进入安装腔内，在动力系统4的作用下形成高压气流，然后通过三通管3进入机头2内，最终从机头2的排风口喷出，为用户提供舒适、凉爽的生活工作环境。
其中，根据本发明的一个实施例，动力系统4包括风轮42和电机31。具体而言，风轮42可转动地设在安装腔内，电机31设在安装腔内且与风轮42相连以驱动风轮42转动产生高速气流。
参照图4，动力系统4主要由风轮42和电机41组成，风轮42设在安装腔内，风轮42外设有风轮外壳，对风轮42起保护作用，风轮42相对于底座14可以发生转动，电机41也设在安装腔内，电机41外有电机外壳，对电机41起保护作用，电机41与风轮42相连接，将电能转换为机械能，为风轮42转动提供动力，驱动风轮42高速转动，带动其周围的气流运动，从而使进入安装腔内的气流形成速度较高的气流。
参照图7，动力系统4还包括扩压器43，扩压器43与风轮42相连且在气流方向上位于出风口142与风轮42的风出口之间，以将高速气流减速、增压成高压气流。
可以理解的是，该动力系统4主要由电机41、风轮42和扩压器43组成。其中，扩压器43也设于安装腔内，并且与动力系统4的风轮42相连接，扩压器43设在风轮42的上方，且扩压器43邻近底座14的出风口142设置，风轮42邻近底座14的进风口141设置，从底座14的进风口141进入的气流在风轮42的作用下形成高速气流，然后流经扩压器43，在扩压器43的作用下形成高压气流，最后从底座14的出风口142排到机头2内，扩压器43将这部分动能充分的转变为热能，以提高压力，即风轮42转动产生的高速气流经过扩压器43时，速度减小，压力变大，将低压高速气流变成高压低速气流。
下面结合附图1至图7具体描述根据本发明实施例的无叶风扇100的工作过程。
如图1至图7所示，根据发明实施例的无叶风扇100包括外壳1、机头2、三通管3、动力系统4和底座14。
外壳1内限定有容纳腔，外壳1上设有多个进风孔，进风孔之间间隔开布置，而且与容纳腔导通，底座14设在容纳腔内，其中，底座14内限定有安装腔，底座14的上端和下端 分别设有与安装腔导通的出风口142和进风口141。
机头2设在外壳1上，机头2内限定有气流通道，机头2的两端分别与底座14的出风口142导通连通，机头2上具有与气流通道导通的多个排风口。
动力系统4设在底座14的安装腔内，其中动力系统由主要由风轮42、电机41和扩压器43组成，风轮42设在安装腔内，风轮42外设有风轮外壳1，对风轮42起保护作用，风轮42相对于底座14可以发生转动，电机41也设在安装腔内，电机41外有电机外壳1，对电机41起保护作用，电机41与风轮42相连接，扩压器43与动力系统4的风轮42相连接，进入底座14的安装腔内的气流在风轮42的作用下形成高速气流，然后进入扩压器43内，在扩压器43的作用下形成高压气流。
三通管3设在底座14的安装腔内且三通管3位于动力系统4的上方，三通管3具有相互连通的第一接口31、第二接口32和第三接口33，第一接口31和第二接口32分别与机头2的第一进口端111和第二进口端112连通，第三接口33与底座14的出风口142相连通。
根据本发明实施例的无叶风扇100在工作时，外部环境中的气流依次通过外壳1的多个进风孔、底座14的进风口141进入安装腔内，由于动力系统4的风轮42相对于底座14可以发生转动，动力系统4的电机41驱动风轮42高速转动，带动其周围的气流运动，从而产生速度较高的气流，由风轮42出风口142排出，然后高速气流进入扩压器43内，在扩压器43的作用下，扩压器43将这部分动能充分的转变为热能，以提高压力，即风轮42转动产生的高速气流经过扩压器43时，速度减小，压力变大，将低压高速气流变成高压低速气流，然后从底座14出风口142排出，流经三通管3的第三接口32，高压气流通过三通管3的分配导向由第一接口31和第二接口32进入机头2的气流通道中，最后由机头2上的多个排风口喷出，带动周围气流运动循环，从而是使用者感觉有冷却效果。
由此，通过在外壳1内设置三通管3，并将三通管3的两个接口分别与机头2的两端连通，使得由外壳1上的进风孔13进入的气流，在动力系统4的作用下形成高压气流，并通过三通管3的另外两个接口分流进入机头2的气流通道内，最终从机头2的排风口排出，大大地提高了无叶风扇100在单位时间内的出风量，给用户带来凉爽、舒适的体验。该无叶风扇100的结构简单，各部件连接可靠，装拆容易，气流运动循环分布均匀，各部件清洁便利，无需拆卸清洗，并且使用者不会触摸到内部部件，使用过程中放心安全，用户体验好。
