螺纹孔332和第三定位部334设置于第一支撑部338的第一端,便于对扩压器330、定子铁芯和骨架120进行装配,降低风机的装配难度,简化风机的装配工艺,提升风机的装配效率。
本实施例提供了一种风机,除上述实施例的技术特征以外,本实施例进一步地包括了以下技术特征。
如图6所示,扩压器330还包括第二支撑部339,第二支撑部339的第一端与第一支撑部338的第一端连接,第二端向骨架120延伸。第三定位部334设置于第二支撑部339上,进而实现对第三定位部334的支撑,提升第三定位部334的强度。
进一步地,第二支撑部339上设置有避空部,避空部与螺纹孔332相对,以避免第二支撑部339与连接件400产生干涉。
在本申请的一个实施例中,提供了一种电器设备,包括如上述任一实施例的风机,因此该电器设备具备上述任一实施例的风机的全部有益效果。
本申请所提供的电器设备包括上述任一实施例的风机,风机可为高速风机。
该高速风机所能达到的第一方面有益效果用较少的零件数量通过螺钉可以一次性把的所有结构件紧固定位,即通过连接件400将电控部件200、定子组件100和风道组件300固定,极大的提高空间利用率和最大程度的降低高速风机重量。
第二方面有益效果是可以有效降低整机的体积,因为零件数量最大程度的减少,使得高度空间利用率大幅提高,可使风机的整机高度可以下降5mm以上,进而减少风机对电器设备内空间的占用。
第三方面有益的效果是生产制造的便易性和高效性,较少的零件数量通过零件上的各种定位特征用于零件的定位和紧固,极大程度的减少生产制造操作工序,提高生产效率。
电器设备包括吸尘器、洗地机或吹风机。
以上所述仅为本申请的优选实施例而已,并不用于限制本申请,对于本领域的技术人员来说,本申请可以有各种更改和变化。凡在本申请的精神和原则之内,所作的任何修改、等同替换、改进等,均应包含在本申请的保护范围之内。
