具体实施方式
依据本公开的一个或多个实施方式提供的导风组件、无叶风扇以及空气净化器，至少能够在一定程度上解决现有技术所存在的吹风电器风力小，且风力比较分散的技术问题。
请参阅图1和图2，示出了本公开第一方面的导风组件110的整体结构图以及全剖图。导风组件110内部设置有第一聚风腔113和第二聚风腔114，第一聚风腔113与第二聚风腔114相连通，风流从第二聚风腔114流动至第一聚风腔113。第二聚风腔114用于容纳风机组件，风机组件所产生的风流汇聚于第二聚风腔114中。第一聚风腔113呈环状，实现环形出风，使得风流具有更大的吹风区域，并且沿出风方向，环状的第一聚风腔113的横截面积呈减小趋势，使得从进风端至出风端风流更聚拢，且风速更大，从而实现聚拢的大风量出风。
第一聚风腔113自进风端至出风端，截面面积(垂直于吹风方向的截面的面积)呈减小趋势，具体可以是沿出风方向线性变化；或者变斜率减小。在某些实施例中，第一聚风腔113的截面面积可以呈阶梯变化。第一聚风腔 113和第二聚风腔114可以是导风组件110中连续设置的两个空腔，也可以是间隔设置、且通过通道连通的两个空腔，本公开不做限制。
具体参阅图2和图3，在一个或多个实施例中，导风组件110包括连接的导风件111和风道112，风道112位于进风侧，导风件111位于出风侧，分体式的结构便于风机组件的拆装。具体的，导风件111包括导风壳1111和支架1112，导风壳1111为中空结构，支架1112设置于导风壳1111的内部，支架1112与导风壳1111之间形成环形的第一聚风腔113。
为了降低流阻，参阅图2，在一个或多个实施例中，导风壳1111为圆管状壳体，内部空腔为圆形空腔，支架1112为锥体，且锥体的小径端靠近风道112，由此可以实现第一聚风腔113的横截面积逐渐缩小。在一个或多个实施例中，支架1112为锥形的罩体，因此该支架1112还可作为其他附件(例如按键、操作面板、电路板等)的安装基础。
参阅图2至图4，在一个或多个实施例中，该导风组件110还包括若干导风片1113，若干导风片1113均位于第一聚风腔113中，且各个导风片1113在第一聚风腔113中沿环周间隔分布，相邻两个导风片1113之间形成导风组件110的出风口115，出风口115的出风面a垂直于导风件111的中轴线b。风流流经各个导风片1113时，导风片1113可以调整风流各处的出风方向，使得风流从导风片1113之间的出风口115中吹出，提高出风聚拢效果。
为了对风流充分导向，导风片1113的数量应当尽量多，一般在4个以上。在一个或多个实施例中，导风片1113为扭转叶片，即导风片1113为自身扭转的片状结构，导风片1113的各个部位与导风件110的轴线之间的夹角α沿出风方向呈减小趋势，具体可以是沿出风方向线性变化、变斜率减小或者呈阶梯式减小，使得流经导风片1113的风流具有向第一聚风腔113中心聚拢的趋势，提高出风聚拢效果。
在一个或多个实施例中，沿出风方向，导风片1113的各个部位与导风件110的轴线之间的夹角α由90°逐渐过渡到5°。也就是说，沿出风方向，导风片1113与出风口115的出风面a之间的角度从5°逐渐过渡到90°，引导风流以近乎垂直于出风口115的出风面a的方向吹出，实现正向出风。
风道112连接于导风件111的进风端，参阅图5和图6，风道112同样为中空结构，风道112的空腔1121形成第二聚风腔114，风道112的壳体上设置有至少一个螺纹孔1122，用于安装螺纹紧固件，实现风道112的安装固定。
为提高聚风效果，参阅图5和图6，在一个或多个实施例中，风道112为涡旋结构，利用涡旋原理提高第二聚风腔114的聚风效果，风道112为一体式结构件，内表面光滑，且减小风阻。基于风道112的涡旋结构，沿出风方向，第二聚风腔114的横截面积呈增大趋势，具体可以是沿出风方向线性变化、变斜率增大或者呈阶梯式增大，风道112整体前端大后端小，较大的 前端便于第二聚风腔114中聚拢的风流充分进入第一聚风腔113。
根据本公开一个或多个实施例提供的导风组件，由于导风组件内部设置有第一聚风腔113和第二聚风腔114，第二聚风腔114用于容纳风机组件，风机组件所产生的风流汇聚于第二聚风腔114中。第二聚风腔114与第一聚风腔113连通，第二聚风腔114汇聚的风流流动至第一聚风腔113中。第一聚风腔113呈环状，实现环形出风，使得风流具有更大的吹风区域，并且沿出风方向，环状的第一聚风腔113的横截面积呈减小趋势，使得从进风端至出风端风流更聚拢，且风速更大，从而实现聚拢的大风量出风。
在本公开第二方面，提供一种无叶风扇，请参阅图7至图10，为无叶风扇1000在各个视角下的整体结构图、全剖图以及***结构图。无叶风扇1000主要包括风机组件130和上述第一方面的导风组件110，风机组件130位于第二聚风腔114中。该无叶风扇1000由于安装有上述第一方面的导风组件110，使得风机组件130产生的风流经聚拢、提速后吹出，从而实现聚拢的大风量出风。
为保护风机组件130以及导风组件110，参见图9和图10，在一个或多个实施例中，该无叶风扇还包括壳体120，壳体120为中空结构，壳体120内部设置有第一腔室121，第一腔室121的开口朝外。在壳体120上还设置有进风口122，进风口122连通第一腔室121与外界环境，用于风机组件130的进风。壳体120同时可以防止用户手指伸入风扇内部而被割伤。第一腔室121中靠近进风口122的位置设置有滤网123，滤网123过滤空气中的灰尘和漂浮物，防止异物进入风机组件130。
导风组件110与壳体120连接，第一聚风腔113连通于第一腔室121的开口处，作为出风端；第二聚风腔114位于第一腔室121内、且靠近进风口122，便于第二聚风腔114中的风机组件130进风。在一个或多个实施例中，导风组件110的风道112位于第一腔室121内部，并且风道112通过螺钉400与壳体120固定连接。风机组件130安装于导风件111上、且位于风道112内部。
风机组件130是风扇的必要功能组件，风机组件130的具体结构可以参照现有技术的相关公开，本公开不做限制。概括来说，风机组件130包括电机131和风轮132，风轮132与电机131的转轴连接，电机131驱动风轮132转动。在一个或多个实施例中，电机131安装于导风件111上，且电机131靠近第一聚风腔113，电机131安装在风轮132前面，风轮132远离第一聚风腔113、且靠近进风口122，便于进风。在一个或多个实施例中，电机131安装在导风件111上并通过螺钉固定，电机131上安装有至少一个减震垫，减震垫位于电机131与导风件111之间，起到减震、降低噪音的作用。
在一个或多个实施例中，该无叶风扇1000还包括外圈140，外圈140呈环状，套设在壳体120或导风组件110上，也可将外圈140套在壳体120和 导风组件110的相接处，外圈140的具***置本公开不做限制。外圈140可以采用完整的环形圈，可以是部分为弧形圈体、部分为平面的结构，在其他实施例中，外圈140还可采用未封闭的结构，外圈140的具体结构形状本公开不做限制。通过设置外圈，外圈可以作为该无叶风扇的提手或放置座，并且起到装饰作用。
为扩大该无叶风扇1000的使用场景，在一个或多个实施例中，外圈140上设置有灯144，用于实现照明功能，且由于外圈140位于壳体120和导风组件110的***，使得灯144对应分布于导风组件110的出风口115的外周，照明区域更大。
为了方便外圈140与壳体120的连接，具体参阅图9和图10，在一个或多个实施例中，外圈140设置为可拆卸结构，外圈140具体包括圈壳141、灯罩142和灯架145，圈壳141和灯罩142可拆卸连接，圈壳141、灯罩142和灯架145均套设于壳体120上，圈壳141为中空结构，圈壳141与壳体120合围成环形的第二腔室143，灯架145安装于第二腔室143中，灯144安装于灯架145上。可以通过改变灯罩142和圈壳141的连接方向，即圈壳141的正装和反装，进而实现灯144的照明方向的调节，使得灯144可以作为美妆照明使用，或者用作夜灯、氛围灯等。
由此，导风组件110、壳体120、风机组件130以及外圈140形成该无叶风扇1000的主机部分100，主机部分100可以直接放置于平面上，也可通过挂钩挂设于物体上，或者手持。为方便使用，在一个或多个实施例中，该无叶风扇1000还包括底座200，壳体120安装于底座200上，方便整个无叶风扇的放置，由此该无叶风扇可设置为落地式或者台式风扇。
底座200除了方便整个无叶风扇1000的放置，还可作为安装基础，例如，在一个或多个实施例中，底座200中设置有电源装置300，电源装置300用于对无叶风扇1000中各用电元件(例如电机131、开关元件等)进行供电，为方便走线，壳体120中对应设置走线架124。电源装置300具体可以是充电电池组件、干电池、带插头的电线中的至少一个，为方便使用，采用TYPE-C接口作为充电接口310，可以通过手机适配器供电。当然，在一个或多个实施例中，电源装置300也可以设置于第一腔室121内，本公开不做限制。
在一个或多个实施例中，该无叶风扇1000具有俯仰调节的功能。具体是主机部分100与底座200之间俯仰角度可以调节。参阅图9，底座200中设置有滑动座210，壳体120中设置能够与滑动座210滑动配合的滑轨160，壳体120通过滑动座210安装于底座200上，使得主机部分100相对于底座200的姿态可调。走线架124与滑轨160连接，便于供电的导线移动。滑轨160具有竖直方向的投影分量，例如滑轨160采用竖直设置的直线或弧形轨道，或者采用倾斜向上的轨道，该竖直方向的投影分量使得滑轨160与滑动座210相对滑动时，主机部分100的出风面a可以调节角度，实现不同方向出风。
在一个或多个实施例中，滑动座210与滑轨160的滑动配合采用滚珠实现。在一个或多个实施例中，参阅图10，在滑动座210的靠近壳体120的一端设置弹簧拨珠211，弹簧拨珠211的外端为滚珠，内部具有弹性件，使得滚珠能够一定程度内缩。滑轨160上设置多个球槽161，球槽161的数量根据实际情况而定，球槽161数量越多，则主机部分100的可调姿态越多，球槽161沿滑轨160的轨迹间隔分布。当主机部分100与底座200之间发生相对滑动时，弹簧拨珠211在滑轨160中滑动，并且可以落入任一个球槽161中，当弹簧拨珠211嵌入某个球槽161后，在没有外力的情况下弹簧拨珠211与球槽161不会发生相对移动，由此可以将主机部分100滑动至任一姿态并固定。
为了方便底座200中各组件的安装和拆卸，在一个或多个实施例中，底座200设置为可拆卸结构，具体参阅图9和图10，底座200包括底盘220和底盘盖230，底盘盖230罩扣于底盘220上，底盘盖230与底盘220可拆卸连接，具体可以采用螺纹或者卡扣结构实现连接。底盘220与底盘盖230限定出一安装空腔，可将电源装置300设置于该安装空腔中。底盘盖230的中部向上凸出，形成一内部中空的对接座231，对接座231靠近主机部分100，因此将滑动座210固定安装于对接座231中。对接座231的设置使得主机部分100与底座200之间具有一定间隔，增加主机部分100的俯仰摆动范围。
该无叶风扇1000的各用电元件通过电路板170统一控制，在一个或多个实施例中，在一个或多个实施例中，电路板170安装于导风组件110中，风机组件130与电路板170电连接，在一个或多个实施例中，具体是风机组件130的电机131与电路板170电连接。为方便布置，电路板170连接于导风件111上，具体可以与导风件111的支架1112连接。电机131位于风轮132与电路板170之间，一方面可以缩短电机131的导线长度，另一方面电机131反装，使得风轮132更靠近进风口122。
该无叶风扇1000还设置有操作面板150和按键支架190，操作面板150安装于按键支架190上，操作面板150上设置有1个以上操作按钮151，便于使用者操控无叶风扇1000的工作状态，电机131、灯144以及操作按钮151均与电机131电连接，操作按钮151具体可以是触控按钮、机械按键等常规按钮形式，具体结构本公开不做限制。按键支架190位于导风件111的空腔中，按键支架190一方面用于支撑操作面板150，另一方面充当导风件111的支架1112。
在一个或多个实施例中，操作面板150位于导风件111的出风面a上，且出风口115环绕操作面板的周沿设置，当将操作面板150的外表面设置为镜面时，该无叶风扇1000还可作为梳妆镜使用。
根据本公开一个或多个实施例提供的无叶风扇，无叶风扇由于安装有上述第一方面的导风组件2100，使得风机组件2300产生的风流经聚拢、提速后吹出，从而实现聚拢的大风量出风。
在本公开第三方面，提供一种空气净化器2000，参阅图11，空气净化器2000包括风机组件2300、空气净化组件2400和导风组件2100，风机组件2300、空气净化组件2400和导风组件2100均安装固定于壳体2200中。导风组件2100的结构参考上述第一方面的导风组件110，具体结构此处不再赘述。风机组件2300位于导风组件2100的风道2120中，风机组件2300包括电机2310和风轮2320，风轮2320与电机2310的转轴连接，电机2310驱动风轮2320转动。电机2310和风轮2320的具体安装方式参考上述第二方面的无叶风扇1000，具体结构此处不再赘述。空气净化组件2400的具体结构可参考现有技术的相关公开，此处不展开说明。
空气净化组件2400位于导风组件2100的第二聚风腔的进风端，空气净化组件2400对空气进行净化，使得进入风道2120中的空气为净化后的空气，风机组件2300产生的风流经聚拢、提速后从导风件2110中吹出，从而实现聚拢的大风量净化空气出风，兼顾净化空气和吹风的效果。
