该风机中，防护件的安装段可拆卸地固定在蜗壳100的进风口处，防护件的限位段插设在风轮200的进风口内，风机应用于空调，空调跌落时，柔性的防护件阻止风轮200发生径向晃动，有效避免风轮200出现卡壳、断裂等的问题；空调安装好之后，再拆卸下防护件即可，防护件不会影响风机正常进风。
在一些示例性实施例中，如图3、图6和图7所示，限位段与风轮200的进风口的周壁之间的径向距离不大于15mm，风机应用于空调，空调跌落时，柔性的防护件可以更好地阻止风轮200发生径向晃动，风轮200不会出现卡壳、断裂等的问题。
可以是，限位段与风轮200的进风口的周壁之间的径向距离设置为5mm；或者可以是，限位段与风轮200的进风口的周壁之间的径向距离设置为10mm；或者可以是，限位段与风轮200的进风口的周壁之间的径向距离设置为15mm等；以上均可实现本申请的目的，其宗旨未脱离本公开的设计思想，在此不再赘述，均应属于本申请的保护范围内。
在一些示例性实施例中，如图3所示，蜗壳100包括：蜗壳本体110，蜗壳本体110的两个端壁均设有开口；和两个导流圈120，两个导流圈120一一对应安装于两个开口处，两个导流圈120的内部形成蜗壳100的两个进风口，蜗壳100的两个进风口包括第一进风口111和第二进风口112。如图1至图5所示，防护件包括第一防护件300和第二防护件400。第一防护件300设于第一进风口111，第二防护件400设于第二进风口112。通过第一防护件300和第二防护件400对风轮200的两端进行限位，可以更好地阻止风轮200发生径向晃动。
下面对第一防护件300的结构进行详细描述。
在一些示例中，如图4所示，第一防护件300的中心轴处设有轴孔330，第一防护件300的侧壁设有轴向和径向均贯通的开口缝340，开口缝340的径向内端与轴孔330相通，开口缝340的径向外端与外界相通；风机还包括：电机500，电机500位于蜗壳100外，电机500的旋转轴与风轮200相连接，第一防护件300自开口缝340可拆卸地固定套设于电机500的旋转轴。空调安装好之后，第一防护件300自开口缝340在电机500的旋转轴上拆卸下，这样第一防护件300不会影响风机正常进风。第一防护件300的限位段310插入风轮200的一个进风口内。
在一些示例中，如图4所示，第一防护件300的安装段320的外周面间隔设有多个第一凸台321，多个第一凸台321的台面抵于第一进风口111的内周面，确保安装段320与第一进风口111的内周面不会自行松脱，而且安装段320与第一进风口111的内周面之间的摩擦力得到减小，方便作业者在蜗壳100上安装上和拆卸下第一防护件300。多个第一凸台321沿周向均布设置，这样不会将导流圈120挤压变形。
再者，风机应用于空调，空调跌落时，轴孔330的孔壁对电机500的旋转轴进行径向定位和支撑，避免电机500的旋转轴发生径向晃动，这样可以有效阻止风轮200发生径向晃动。
可以是，多个第一凸台321为两个；或者可以是，多个第一凸台321为三个；或者可以是，多个第一凸台321为四个等；以上均可实现本申请的目的，其宗旨未脱离本公开的设计思想，在此不再赘述，均应属于本申请的保护范围内。
在一些实施例中，第一凸台321的径向高度为2mm至6mm。可以是，第一凸台321的径向高度为2mm；或者可以是，第一凸台321的径向高度为4mm；或者可以是，第一凸台321的径向高度为6mm等；以上均可实现本申请的目的，其宗旨未脱离本公开的设计思想，在此不再赘述，均应属于本申请的保护范围内。
在一些示例中，如图4所示，第一防护件300的安装段320的外周面还设有第二凸台322，第二凸台322位于蜗壳100外，第二凸台322的朝向蜗壳100的侧面抵于第一进风口111的外端面，避免第一防护件300自第一进风口111完全进入蜗壳100内部，致使第一防护件300的防护功能丧失。
可以是，第二凸台322为环形凸台；或者可以是，第二凸台322为沿周向间隔设置的多个弧形凸台等；以上均可实现本申请的目的，其宗旨未脱离本公开的设计思想，在此不再赘述，均应属于本申请的保护范围内。
在一些示例中，如图4所示，第一防护件300的朝向蜗壳100外部的端面设有抓取部323，抓取部323设置成供作业者快速拆装第一防护件300，以此来降低操作难度。
在一些实施例中，如图4所示，抓取部323包括多个抓取孔，多个抓取孔位于轴孔330的一旁，且在轴向上贯通第一防护件300。手指可以伸入多个抓取孔内实现快速取下第一防护件300。
下面对第二防护件400的结构进行详细描述。
在一些示例中，如图5所示，第二防护件400的安装段420的外周面间隔设有多个第一凸台421，多个第一凸台421的台面抵于第二进风口112的内周面，确保安装段420与第二进风口112的内周面不会自行松脱，而且安装段420与第二进风口112的内周面之间的摩擦力得到减小，方便作业者在蜗壳100上安装上和拆卸下第二防护件400。多个第一凸台421沿周向均布设置，这样不会将导流圈120挤压变形。第二防护件400的限位段410插入风轮200的另一个进风口内。
可以是，多个第一凸台421为两个；或者可以是，多个第一凸台421为三个；或者可以是，多个第一凸台421为四个等；以上均可实现本申请的目的，其宗旨未脱离本公开的设计思想，在此不再赘述，均应属于本申请的保护范围内。
