请一并参阅图1～图24，本发明实施方式的用于无叶风扇的基座10包括本体部11、动力系统12及弹性减振装置16。
本体部11包括外壳11a，动力系统12收容在外壳11a内，动力系统12用于产生高压气流，动力系统12包括连接体1212，弹性减振装置16设置在外壳11a内，弹性减振装置16包括弹性件162、环形的连接件166及与连接件166连接的环形的固定片163，固定片163及连接件166依次套设在连接体1212上，动力系统12通过连接体1212承载在连接件166上，弹性件162弹性抵持在固定片163与连接件166之间。
在本发明实施方式的，由于在固定片163与连接件166之间弹性抵持有弹性件162，弹性件162具有一定的减震作用，这样在弹性减振装置16的位置固定时，在动力系统12工作时，动力系统12的震动通过连接体1212作用在连接件166上，连接件166的震动转化为弹性件162的弹性形变，进而可有效缓冲动力系统12的震动，尤其是竖直方向上的震动，从而可降低动力系统12工作时引起的振动噪音，从而提高了用户体验。
需要说明的是，弹性减振装置16的固定方式可根据具体情况进行设置。例如，在一些例子中，基座10包括用于支撑的环形的壳体(图未示出)，壳体位于外壳11a内，弹性减振装置16的一端可直接安装在壳体上，或间接安装在壳体上，这样在弹性减振装置16的位置固定后，即可通过弹性件162有效缓冲动力系统12的震动。
再有，连接体1212对整个动力系统12既起着支撑及固定的作用，又对整体动力系统12具有保护作用。在连接体1212的位置固定时，整个动力系统12的位置是固定的。连接体1212的形状可根据具体情况进行设置，例如在一些例子中，连接体1212呈环形。
请结合图12～图14，在一个实施方式中，连接件166的下端面1663向下延伸形成有扣位部16a。固定片163的内侧开设有定位槽163a。扣位部16a与定位槽163a配合连接以使得弹性件162弹性抵持在固定片163与连接件166之间。
如此，在连接件166与固定片163之间形成有较大的减震缓冲空间，这样动力系统12工作时产生震动可由弹性件162弹性形变而得到有效缓冲，同时连接件166与固定片 163的连接方式较为简单且便于装配，并在一定程度上减少了螺钉的使用，简化了结构。
在一个示例中，弹性件162为弹簧。如此，弹性件162的弹性较大。可以理解，在其它例子中，弹性件162可为其它弹性件，例如是弹性的橡胶块等具有能够提供预定回复力的弹性件。
在一个实施方式中，连接件166的下端面1663向下延伸形成有定位柱16b。固定片163开设有定位孔163b。定位柱16b穿设弹性件162及定位孔163b。
如此，弹性件162能够稳定地抵持在连接件166与固定片163之间，这样在动力系统12工作时，弹性件162能够有效缓冲动力系统12的震动。
在本发明示例中，弹性件162的数目为多个，多个弹性件162沿连接件166的圆周方向分布，这样减震效果更佳。可以理解，定位柱16b的数目及定位孔163b的数目与弹簧162的数目对应。
在一个实施方式中，连接件166的上端面形成有至少两个限位件1662。至少两个限位件1662间隔设置，连接体1212的外端面形成有向外凸出的第一凸起筋1213，第一凸起筋1213卡设在相邻的两个限位件1662之间。
如此，由于第一凸起筋1213卡设在相邻的两个限位件1662之间，这样在连接件166套设在连接体1212上时，限位件1662能够防止连接体1212在圆周方向上发生超过预期的转动，从而能够防止动力系统12工作时在圆周方向上发生超过预期的转动，这样保证了动力系统12工作时的稳定性。预期的转动可设置为不转动或在某个角度范围内的转动。
需要说明的是，在本发明实施方式中，在弹性减振装置16的位置固定时，连接件166周向的位置也是固定的，即连接件166本身不会发生转动。
同时，由于第一凸起筋1213位于连接件166的上端，也能够防止连接件166相对于连接体1212向上窜动而影响弹性减振装置16与动力系统12连接的稳定性。
在一个实施方式中，限位件1662的数目大于或等于4个。限位件1662的数目为偶数个，多个限位件1662沿连接件166的圆周方向间隔设置。第一凸起筋1213的数目为多个，多个第一凸起筋1213沿连接体1212的圆周方向间隔设置。限位件1662的数目为第一凸起筋1213的数目的2倍。每个第一凸起筋1213卡设在对应的相邻的两个限位件1662之间。
如此，多个限位件1662分别为卡设在对应的相邻的两个限位件1662之间，这样可使得连接体1212在圆周方向上的受力更加均衡，从而进一步提高了动力系统12的稳定性。
需要说明的是，限位件1662的数目可根据具体情况进行设置，同时，第一凸起筋 1213的数目也可根据情况进行设置。可以理解，限位件1662的数目与第一凸起筋1213的数目对应。
例如，在一个例子中，限位件1662的数目为8个，8个限位件1662沿连接件166的圆周方向间隔设置，第一凸起筋1213的数目为4个，4个第一凸起筋1213沿连接体1212的圆周方向间隔90度设置，每个第一凸起筋1213卡设在相邻的两个限位件1662之间。由于4个第一凸起筋1213为连接体1212的圆周方向间隔90度设置，并且每个第一凸起筋1213卡设在相邻的两个限位件1662之间，这样第一凸起筋1213与限位件1662配合的方式使得连接体1212在圆周方向上的受力更加均衡，从而进一步提高了动力系统12的稳定性。
在一个实施方式中，弹性减振装置16包括减震套165。减震套165形成有凸出的配合部1651。配合部1651的内侧开设有第一卡槽1652。第一凸起筋1213卡入第一卡槽1652内以使得减震套165套设在连接体1212上。配合部1651卡设在相邻的两个限位件1662之间。配合部1651隔开限位件1662与第一凸起筋1213。连接体1212通过配合部1651承载在连接件166上。
如此，这样相当于在连接件166与第一凸起筋1213之间设置了具有减震作用的减震套165，从而可进一步缓冲动力系统12与弹性减振装置16之间的相互作用力，并可进一步有效减缓动力系统12的振动，从而降低动力系统12振动时的噪音。
需要说明的是，减震套165可根据具体情况进行设置，在一些例子中，减震套165可只包括配合部1651，这样也能够实现缓冲动力系统12与弹性减振装置16之间的相互作用力的作用，并且结构简单。
另外，减震套165的形状可根据具体情况进行设置，例如在一些例子中，减震套165呈环形。
在一个实施方式中，减震套165呈环形，连接体1212呈环形。配合部1651的数目为多个。多个配合部1651沿减震套165的圆周方向间隔设置。每个配合部1651开设有第一卡槽1652。第一凸起筋1213的数目为多个。多个第一凸起筋1213沿连接体1212的圆周方向间隔设置。每个第一凸起筋1213卡入对应的第一卡槽1652内。
如此，多个第一卡槽1652分别卡入对应的多个第一凸起筋1213的配合方式使得连接体1212在周向的受力更加均衡，从而提高了动力系统12工作时的稳定性。
在一个例子中，减震套165形成有4个凸出的配合部1651，4个配合部1651沿减震套165的圆周方向间隔90度设置，每个配合部1651的内侧开设有第一卡槽1652，第一凸起筋1213的数目为4个，4个第一凸起筋1213沿连接体1212的圆周方向间隔90度设置，4个第一凸起筋1213能够分别卡入对应的第一卡槽1652内。如此，减震套165 能够更加稳定地套设在连接体1212上，动力系统12的受力更加均衡。
在一个例子中，减震套165由硅胶材料构成。如此，加工简单，易于制造，并且减震效果较好。
请结合图7、图8及图14，在一个实施方式中，连接件166的内侧开设有第二卡槽1665，连接体1212的外端面1215形成有向外凸出的第二凸起筋1214。第二凸起筋1214卡设第二卡槽1665以使得弹性减振装置16定位在连接体1212上。
如此，由于第二凸起筋1214为卡设第二卡槽1665，这样在连接件166的位置固定时，弹性减振装置16相对于连接体166的位置也是固定的。同时，第二凸起筋1214卡设第二卡槽1665的配合方式具有限位的作用，这样能够防止连接体1212在圆周方向上发生超过预期的转动，从而能够防止动力系统12工作时在圆周方向上发生超过预期的转动，这样保证了动力系统12工作时的稳定性。预期的转动可设置为不转动或在某个角度范围内的转动。
同时，由于第一凸起筋1213卡设第一卡槽1665，这样能够限定减振装置16在动力系统12外的安装位置，保证了减振装置16的快速安装。
在本发明实施方式中，连接体1212的外端面1215形成有第一凸起筋1213及第二凸起筋1214，第一凸起筋1213及第二凸起筋1214均向外凸出，第一凸起筋1213与第二凸起筋1214间隔设置，第一凸起筋1213基本呈弧形，第二凸起筋1214基本呈锥体状。第一凸起筋1213位于第二凸起筋1214的上端。这样第一凸起筋1213及第二凸起筋1214的结合进一步提高了动力系统12工作时的稳定性，使得动力系统12工作时更加可靠。
在一个实施方式中，连接体1212呈环形。第二卡槽1665的数目为多个。多个第二卡槽沿1665沿连接件166的圆周方向间隔设置。第二凸起筋1214沿连接体1212的圆周方向间隔设置。每个第二凸起筋1214卡设对应的第二卡槽1665。
如此，多个第二凸起筋1214分别卡设对应的多个第二卡槽1665，这样使得连接体1212在周向上的受力更加均衡，从而进一步提高了动力系统12的稳定性。
需要说明的是，第二凸起筋1214的数目可根据具体情况进行设置，同时，第二卡槽1665的数目也可根据情况进行设置。可以理解，第二凸起筋1214的数目与第二卡槽1665的数目对应。
在本发明实施方式中，第一凸起筋1213与第二凸起筋1214间隔设置，第一凸起筋1213位于第二凸起筋1214之上。第二凸起筋1214卡设第二卡槽1665，在动力系统12工作时，第二卡槽1665的两个相对的侧壁限定了第二凸起筋1214的位置，这样动力系统不会在圆周方向上发生超过预期的转动，也就保证了动力系统12工作时的稳定性。
在一个实施方式中，基座10包括气流导通部13及扩压器121。扩压器121包括环形的内圈体1211及连接体1212。内圈体1211与连接体1212间隔设置，内圈体1211收容在连接体1212内。内圈体1211连接气流导通部13的下端。本体部11包括位于外壳11a内的支架111(见图19、图20及图21)。气流导通部13安装在支架111上。气流导通部13的底部形成有固定部161。固定片163与固定部161固定连接。动力系统12通过弹性减振装置16与气流导通部13连接以通过气流导通部13弹性悬置在支架111上。动力系统12与外壳11a的内壁隔开。
如此，外壳11a及支架111对动力系统12具有支撑及保护的作用，同时由于动力系统12通过弹性减振装置16弹性悬置在支架111上并与外壳11a的内壁隔开，这样可防止由动力系统12工作时产生的震动传递至外壳11a，从而可降低由动力系统12工作时引起的振动噪音，从而提高用户体验。
同时，由动力系统12产生的高压气流可直接进入气流导通部13，并可由气流导通部13导出，这样可通过气流导通部13限定高压气流的流动方向，同时弹性减振装置16与固定部161固定连接以通过气流导通部13安装在支架111上的设置方式使得动力系统12与支架111之间的相互作用力较小，从而降低了动力系统12的振动对支架111的影响，这样保证了动力系统12弹性悬置在支架111上的稳定性。
需要说明的是，弹性减振装置16可缓冲动力系统12与外壳11a之间的相互作用力，并且在动力系统12工作时，动力系统12在外壳11a内可移动一定行程，即具有一定的震动缓冲空间，动力系统12能够通过在外壳11a内移动而消减震动。
再有，在动力系统12移动以消减震动时，因动力系统12是通过弹性减振装置16弹性悬置在支架111上，这样动力系统12的移动并不改变弹性减振装置16与动力系统12的连接，也不会影响弹性减振装置16与动力系统12连接的稳定性，在动力系统12停止工作时，动力系统12能够恢复至初始的位置状态。本发明实施方式无叶风扇的基座10可应用于无叶风扇100中。无叶风扇100包括用于无叶风扇的基座10。
另外，气流导通部13的底部位于气流导通部13的下端的外侧。在一些例子中，固定部161围绕气流导通部13的下端。
请结合图1及图17，在一些例子中，用于无叶风扇的基座10包括底座15。底座15位于用于无叶风扇的基座10的底部。支架111及外壳11a设置在底座15上，底座15用于支撑基座10。底座15能够提高用于无叶风扇的基座10的稳定性。
在本发明实施方式中，支架111及外壳11a均呈环形。外壳11a开设有多个空气进口141，多个空气进口141沿外壳11a的圆周方向阵列排布，这样进气面积较大且可保证外壳11a的强度。动力系统12用于通过空气进口114将空气吸入，再将吸入的空气 压缩成高压气流。
在图19的例子中，气流导通部13安装在支架111上。弹性减振装置16的一端与固定部161固定连接以通过气流导通部13安装在支架111上。动力系统12安装在弹性减振装置16的另一端以通过气流导通部13弹性悬置在支架111上。这样气流导通部13与弹性减振装置16的结合设置增强了动力系统12弹性悬置的稳定性。
在一个实施方式中，气流导通部13的两侧面向外延伸形成有安装台132，安装台132与固定部161固定连接。气流导通部13通过安装台132架设在支架111的上端。
如此，气流导通部13为通过安装台132安装在支架111上，由于安装台132与支架111的接触面积较大，这样使得气流导通部13能够较为稳定地固定在支架111上。
具体地，安装台132开设有通孔134。支架111的上端形成有固定件(图未示出)。固定件与通孔134对应，并可通过螺钉进行紧固。固定件与通孔134的配合方式较为简单，且结构稳定性较好。
在本发明示例中，固定件为螺钉柱。如此，加工简单，且结构稳定性好。
在一个实施方式中，基座10包括紧固件(图未示出)，紧固件连接固定部161及固定片163而将动力系统12与气流导通部13的下端连接。
具体地，紧固件例如是螺钉，固定片163上开设有螺钉孔164，紧固件从上至下依次穿设固定部161的第二固定孔1611及螺钉孔164而将气流导通部13与固定片163螺纹连接。如此，螺纹连接的方式比较稳定，并且螺钉来源广泛，使用方便。
在一个实施方式中，固定部161开设有4个第二固定孔1611，4个第二固定孔1611间隔设置，固定片163上开设有螺钉孔164，螺钉孔164的数目为4个，4个螺钉孔164间隔设置，4个第二固定孔1611分别与对应的螺钉孔164以螺纹连接的方式实现固定连接。如此，固定部161及固定片163连接稳定，并且多个第二固定孔1611分别与多个螺钉孔164中对应的螺钉孔164对应连接的方式提高了整体弹性减振装置16的稳定性。
在一个实施方式中，扩压器121为一体成型结构。如此，结构简单，便于加工，制造成本低。
在一个实施方式中，扩压器121的上端开设有第一出风口123，内圈体1211围绕第一出风口123，内圈体1211沿高压气流方向呈渐缩的形状。如此，内圈体1211可对动力系统12产生的高压气流具有汇集的作用，并在一定程度上对高压气流具有减速增压的作用。
在一个示例中，为了防止动力系统12发生过大的震动，连接体1212形成有用于抵持固定片163的弧面1212a。弧面1212a与固定片163之间的距离限定了动力系统12的震动行程。在某些实施方式中，弧面1212a与固定片163之间的距离是指弧面1212a与 固定片163之间的最小距离。
在本发明示例中，内圈体1211与连接体1212为固定连接，连接体1212围绕内圈体1211。固定片163的内侧形成有第一配合槽1631，第一配合槽1631能够与第二凸起筋1214配合。连接件166的内侧形成有第二配合槽1664，第二配合槽1664能够与第二凸起筋1214配合。在安装弹性减振装置16时，可先将弹性件162、固定片163及连接件166组装成组件，具体地，可先使得第一配合槽1631对准第二配合槽1664，然后使得连接件166的定位柱16b穿设弹性件162及固定片163的定位孔163b，并同时使得扣位部16a与定位槽163a配合连接以使得弹性件162弹性抵持在固定片163与连接件166之间，这样便完成了弹性件162、固定片163及连接件166的组装。其中，第一配合槽1631及第二配合槽1664均具有定位的作用，这样方便安装。
然后可再将第二凸起筋1214卡入对应的减震套165的第二卡槽1652内以使得减震套165套设在连接体1212上。然后可将由弹性件162、固定片163及连接件166组装成的组件一并套设在连接体1212上。具体地，可将固定片163上的第一配合槽1631与减震套165的配合部1651配合以使得第二凸起筋1214及配合部1651一并卡入第一配合槽1631，这时可使组件向连接体1212方向移动并使得第二凸起筋1214及配合部1651一并依次穿过第一配合槽1631及第二配合槽1664，然后可旋转组件，使得第一凸起筋1213对准对应的第一卡槽1665以使得第一凸起筋1213能够卡设对应的第一卡槽1665，并同时使得配合部1651能够卡设在相邻的两个限位件1662之间，从而使得组件整体套设在连接体1212上。这时配合部1651隔开限位件1662与第二凸起筋1214，减震套165位于连接件166的上端。这样便使得组件稳定地套设在了连接体1212上。由此可知，第一配合槽1631及第二配合槽1664的设置方便了组件整体的安装，在一定程度上简化了弹性减振装置16的安装步骤。
然后只需通过紧固件连接固定部161及固定片163便可以将动力系统12与气流导通部13的下端连接。
请结合图2～图9及图15及图16，在一个实施方式中，基座10包括环形的第一密封件17。气流导通部13的下端开设有第一进风口1311。扩压器121开设有第一出风口123，内圈体1211围绕第一出风口123。第一进风口1311与第一出风口123连通，第一密封件17密封连接气流导通部13的下端和内圈体1211。
如此，气流可由动力系统12的第一出风口123进入气流导通部13的第一进风口1311。同时，第一密封件17可保证第一进风口1311与第一出风口123的气密性，并可避免高压气流的损失，同时可防止由于漏气而产生噪音。
在一个实施方式中，气流导通部13的下端形成有围绕第一进风口1311的环形的安 装槽131，气流导通部13的下端形成有环形的凸筋13a，凸筋13a围绕安装槽131。第一密封件17的上端面171开设有环形的密封槽172，凸筋13a卡入密封槽172以使得第一密封件17密封连接气流导通部13的下端和内圈体1211。
如此，由于密封槽172与凸筋13a配合，这样密封槽172与凸筋13a的配合设置的方式提高了第一进风口1311与第一出风口123的气密性，从而可避免高压气流在第一进风口1311与第一出风口123损失，增强了密封效果。
再有，凸筋13a卡入密封槽172的密封方式还保证了第一密封件17的位置较为固定。
在一个实施方式中，密封槽172的形状与凸筋13a的形状相匹配。如此，由于密封槽172的形状与凸筋13a的形状相匹配，这样可提高第一密封件17与气流导通部13的下端配合的气密性，从而可防止高压气流在第一进风口1311损失，增强了密封效果。
在一个例子中，第一密封件17由硅胶材料构成。这样加工简单，易于制造，同时由硅胶材料构成的第一密封件17对动力系统12具有一定的减震效果，从而可降低动力系统12因动力系统12的电机高速运转振动而引起的噪音。
在一个实施方式中，第一密封件17的内侧形成有与内圈体1211的外壁面1216的形状相匹配的密封面173。密封面173与内圈体1211的外壁面1216接触密封以密封连接气流导通部13的下端和内圈体1211。
如此，由于密封面173的形状与内圈体1211的外壁面1216的形状相匹配，这样提高了第一密封件17与内圈体1211配合的气密性，从而可避免高压气流在第一出风口123损失，增强了密封效果。
在一个实施方式中，内圈体1211的外壁面1216上形成有向外凸起的突起筋位1217。第一密封件17的下端抵持在突起筋位1217上。
如此，突起筋位1217对第一密封件17具有支撑及固定的作用，可防止第一密封件17脱落。
在一个实施方式中，突起筋位1217的数目为多个，多个突起筋位1217沿内圈体1211的周向间隔分布。
如此，多个突起筋位1217可使得突起筋位1217作用在第一密封件17上的作用力更加均匀，从而提高了第一密封件17与内圈体1211配合的稳定性。
在一个实施方式中，第一密封件17的下端形成有抵持突起筋位1217的抵持面174。如此，第一密封件17的下端与突起筋位1217的接触面积较大，这样使得第一密封件17的下端具有较大的受力面积，从而保证了第一密封件17抵持在突起筋位1217上的稳定性。
在一个实施方式中，抵持面174呈环形，抵持面174围绕密封面173。如此，由于抵持面174呈环形，并且抵持面174围绕密封面173，这样可使得密封面173在与内圈体1211的外壁面1216接触密封时，密封面173各处的受力更加均匀，从而保证了密封面173与内圈体1211的外壁面1216接触密封的气密性。
在本发明实施方式中，扩压器121包括间隔设置的内圈体1211及连接体1212。内圈体1211呈环形，连接体1212呈环形。内圈体1211连接气流导通部13的下端。内圈体1211收容在连接体1212内，连接体1212对动力系统12具有支撑及保护的作用。第一密封件17的下端与内圈体1211的上端配合。第一密封件17密封连接气流导通部13的下端与内圈体1211的上端。第一密封件17形成有与内圈体1211的外壁面1216的形状相匹配的密封面173。密封面173与内圈体1211的外壁面1216紧密贴合而实现接触密封，密封面173与内圈体1211的外壁面1216密封连接气流导通部13的下端和内圈体1211的上端。内圈体1211的外壁面1216形成有向外凸起的突起筋位1217，突起筋位1217位于内圈体1211及连接体1212之间。第一密封件17的下端抵持在突起筋位1217上。突起筋位1217的数目为多个，多个突起筋位1217沿内圈体1211的周向间隔分布。
在本发明实施方式中，动力系统12包括扩压器121、电机124、风轮125、电机外壳126及风轮外壳127。扩压器121连接风轮外壳127。电机124收容在电机外壳126内，电机外壳126对电机124具有支撑及保护的作用。风轮125收容在风轮外壳127内，风轮外壳127对风轮125具有支撑及保护的作用。连接体1212构成扩压器121的外壳。扩压器121对高压气流具有减速增压的作用。连接体1212、电机外壳126及风轮外壳127可通过螺钉固定。整个动力系统12通过连接体1212和弹性减振装置16悬置在外壳11a内。
如此，电机124驱动风轮125旋转，以将外界空气吸入基座10内，并在风轮125的高速旋转下，产生高速的气流。然后，产生的高速气流由扩压器121减速增压后进入气流导通部13内，同时电机外壳126、风轮外壳127及连接体1212具有减震降噪的作用。
在一个实施方式中，气流导通部13为三通管结构。这样可通过三通管结构对高压气流进行分流。
在本发明实施方式中，气流导通部13基本呈T形状。如此，气流导通部13的结构较为简单，且T形状的外形不影响无叶风扇100的使用。
在一个实施方式中，气流导通部13为一体成型结构。如此，结构简单，便于加工，制造成本低。
在一个实施方式中，气流导通部13的上端形成有向下凸出的弧形导流件136。弧形 导流件136包括弧形导流内表面1361。弧形导流内表面1361朝向动力系统12的第一出风口123，并用于将高压气流分成两股气流以分别从气流导通部13的两侧出射。
如此，在弧形导流件136的导向作用下，高速气流能够顺着弧形导流内表面1361较顺畅地流出，这样一方面可以减小气流在气流导通部13的流动损失，另一方面也可以减少气流导通部13内气流流动的噪声，从而保证出风效果。
请一并参阅图17～图24，本发明实施方式的无叶风扇100包括上述任一实施方式的用于无叶风扇的基座10。
在本发明实施方式的无叶风扇100中，由于在固定片163与连接件166之间弹性抵持有弹性件162，弹性件162具有一定的减震作用，这样在弹性减振装置16的位置固定时，在动力系统12工作时，动力系统12的震动通过连接体1212作用在连接件166上，连接件166的震动转化为弹性件162的弹性形变，进而可有效缓冲动力系统12的震动，尤其是竖直方向上的震动，从而可降低动力系统12工作时引起的振动噪音，从而提高了用户体验。
在一个实施方式中，无叶风扇100包括设置基座10上的机头20。机头20包括间隔的两个出风部21，每个出风部21开设有风道211。每个出风部21开设有第二出风口212。第二出风口212连通风道211。动力系统12与风道211连通并用于将高压气流送入风道211并经第二出风口212向外喷射。
如此，由动力系统12产生的高压气流可直接由机头20的第二出风口212喷射出，两个出风部21保证了出风面积。
具体地，动力系统12通过气流导通部13连接两个出风部21。气流导通部13为三通管结构。气流导通部13的下端开设有第一进风口1311。第一进风口1311与动力系统12的第一出风口123连通。气流导通部13的上端两侧分别开设有两个出气口1312。第一进风口1311连通两个出气口1312。两个出气口1312分别连通两个出风部21的对应的风道211。高压气流由第一进风口1311进入气流导通部13内。气流导通部13用于将进入气流导通部13内的高压气流分流成两股气流，并使得两股气流分别由两个出气口1312进入两个出风部21的对应的风道211。
如此，由于动力系统12通过气流导通部13连接两个出风部21，且气流导通部13为三通管结构，这样由动力系统12产生的高压气流为经由气流导通部13分流后再进入两个出风部21的对应的风道211，如此，不需要在两个出风部21的风道211内单独设置用于气流分流的部件结构，从而简化了两个出风部21的风道211的结构，降低了风道211的加工难度，同时，三通管结构加工较为简单，易于实现，并且在三通管结构的导向及分流作用下，可将气流充分导向对应的风道211内，从而减小了气流损失，保证 了气流的分流效果，并且气流先分开再进入风道211的方式可降低风道211内的气动噪音，进而提升了用户体验。
在一个实施方式中，机头20包括间隔的两个进风部22。基座10形成有两个连接端10a。风道211开设在每个出风部21内及每个进风部22内。每个进风部22的一端连接对应的出风部21的一端，每个进风部22的另一端连接基座10对应的一个连接端10a。每个进风部22开设有第二进风口221。第二进风口221连通动力系统12的第一出风口123及风道211。风道211连通第二进风口221及第二出风口212。
如此，风道211贯通出风部21及进风部22，使得气流可充分由第二进风口221进入风道211内，而进风部22设置在出风部21的一端，既可以用于进风，又可通过进风部22连接连接端10a，以增加无叶风扇100的其它功能，提升用户体验。
在本发明示例中，进风部22位于用于机头20的下端，机头20包括间隔的两个第二进风口221，两个第二进风口221对称设置在机头20的内侧，连接端10a为气流导通部13的上端两侧所形成的连接端，该连接端开设有出气口1312，即每个进风部22的另一端连接气流导通部13对应的一个连接端。气流由第二进风口221进入风道211，并沿风道211由下而上流动，然后再由第二出风口212喷射出。
需要指出的是，“下端”、“内侧”是无叶风扇100在正常使用状态下的位置状态，例如图15所示无叶风扇100的位置状态。
在一个实施方式中，每个进风部22的另一端与基座10对应的一个连接端10a卡接。如此，连接方式较为简单且便于拆卸。
具体地，在本发明示例中，无叶风扇100包括两个固定卡扣40，气流导通部13的连接端的上端面均形成有固定柱135，每个固定柱135开设有第一固定孔1351，每个进风部22的端部形成有配位槽22a，固定卡扣40的一端与配位槽22a配合连接，固定卡扣40的另一端与固定柱135第一固定孔1351固定连接，这样两个进风部22分别通过固定卡扣40实现了与气流导通部13的两端的卡接配合。例如，可利用螺钉与固定孔的连接来固定固定卡扣40和固定柱135。
在一个实施方式中，无叶风扇100包括两个第二密封件30。每个连接端10a开设有一个出气口1312每个第二密封件30密封出气口1312与第二进风口221的结合处。
如此，可保证两个出气口1312与两个第二进风口221之间的密封效果，从而防止气流的损失。
在本发明示例中，连接端10a为气流导通部13上端两侧所形成的连接端，第二密封件30为环形的密封件，第二密封件30由硅胶材料构成。这样加工简单，易于制造。
在一个实施方式中，机头20包括第一风道件23及第二风道件24。第一风道件23 连接第二风道件24以形成两个出风部21及两个进风部22。第一风道件23的侧部开设有第二出风口212。
如此，通过第一风道件23连接第二风道件24的方式以形成进风部22及两个出风部21，结构简单，便于制造，同时第二出风口212单独开设在第一风道件23上，而非由两个风道件连接而成，使得第二出风口的内壁密封性较好，避免第二出风口内壁漏出而产生噪声。
在一个实施方式中，机头20呈倒U型，第一风道件23为内侧件，第二风道件24为外侧件。
如此，第二出风口212位于用于机头20的内侧件上，可避免外侧件对第二出风口212喷射出的气流产生干扰，并且可在一定程度上防止灰层由第二出风口212进入风道211内，同时倒U型的机头20结构较为简单，美观，并使得由第二出风口212喷射出的气流覆盖面积较大，提升用户体验。
