上述所述的若干个风叶片3与顶面板1是一体注塑成型，顶面板1中央设置与电机轴连接的连结座11，所述风叶片3的端面31上还设有若干第一凸台 33，底面板2上设有与第一凸台33配合的凹槽24，第一凸台33嵌入凹槽24里面并通过焊接结合在一起。减少焊接点，降低了漏焊问题，提高焊接精度，焊接牢固，有效解决风轮在运行时跳动大和平横性差问题，外形美观。
上述所述的顶面板1的上端面14边缘凸出有若干片辅助风叶12，辅助风叶12与若干风叶片3分布在顶面板1两侧，所述辅助风叶12、若干风叶片3和顶面板1是一体注塑成型。
上述所述凹槽24的底面241凸出若干焊点242，当第一凸台33嵌入凹槽24里面后，第一凸台33的顶面与焊点242的顶部接触，通过焊接将第一凸台33和焊点242焊接在一起。
上述所述若干个焊点242间隔均布在凹槽24的底面241里。
上述所述每个风叶片3的端面31两端分别设有第一凸台33,两端的第一凸台33之间形成一凹坑34。
上述所述每个风叶片3的端面31的定位柱32位于凹坑34中。
上述所述的定位柱32有两个，分别位于凹坑34的两端。
实施例三：
如图18至图20所示，一种鼓风机，包括蜗壳4、盖板5、电机6、电机轴7和风轮9，蜗壳4与盖板5安装连接在一起形成空腔8，风轮9安装在空腔8里面，蜗壳4上设置排风口41，盖板5设置入风口51，其特征在于：所述的风轮9是实施例一所述的任何一项的风轮9。
以上实施例为本发明的较佳实施方式，但本发明的实施方式不限于此，其他任何未背离本发明的精神实质与原理下所作的改变、修饰、替代、组合、简化，均为等效的置换方式，都包含在本发明的保护范围之内
