图l至图6示出了本发明第一个实施例的贯流风机。从图1至图6中可以看到，贯流风机100包括蜗壳1、蜗舌2、叶轮3和驱动叶轮转动工作的电机6；叶轮3包括第一端版17、第二端版18、在圆周方向上间隔排列的多个叶片5、叶轮轴10和凸缘25；第一端版17和第二端版18都为圆形板，多个叶片5的两端分别与第一端版17和第二端版18固定连接；叶轮轴10为具有中心通孔11的转轴，叶轮轴10与第一端版17固定连接；凸缘25与第二端版18固定连接，凸缘25具有通孔29，用于使电机6的电机轴7能插入固定；蜗壳1与蜗舌2相隔一定的距离，蜗壳1的两端分别与第一固定架15和第二固定架16固定连接，蜗舌2的两端也分别与第一固定架15和第二固定架16固定连接。
在本实施例中，贯流风机100还包括导流装置20，导流装置20包括第一导流件23、第一固定板21、第二固定板22、第一固定杆12和第二固定杆13，第一固定板21和第二固定板22都为圆形板，第一导流件23的两端分别与第一固定板21和第二固定板22固定连接，第一固定杆12和第二固定杆13分别与第一固定板21和第二固定板22固定连接。
从图1至图6中还可以看到，轴承座8与第一固定架15固定，在轴承座8上设置有轴承9，轴承9支撑叶轮3的叶轮轴10，导流装置20的第一固定杆12能插入到轴承座8的通孔19中并与轴承座8固定，第一固定杆12被设置于叶轮轴10的中心通孔11中并且不与叶轮轴10相接触。
在本实施例中，电机6与第二固定架16固定连接，导流装置20的第二固定杆13通过固定件14与电机6的外壳进行固定，电机6的电机轴7具有中心通孔，第二固定杆13位于电机轴7的中心通孔中并且不与电机轴7相接触。
在本实施例中，第一导流件23、第一固定板21和第二固定板22都位于叶轮3的内部空腔4中。由于第一固定杆12不与叶轮轴10相接触，第二固定杆13不与电机轴7相接触，这样当叶轮3在电机6的驱动下沿着ω方向进行转动工作时，整个导流装置20不会跟随叶轮3进行转动。
从图5中可以清楚地看到，第一导流件23位于叶轮3的内部空腔4中，叶轮3包括在圆周方向上间隔排列的多个叶片5，每个叶片都具有内缘51和外缘52，第一导流件23包括吸入端231、吹出端232、第一侧面233和第二侧面234，其中，第一侧面233为一平面，第二侧面234为外凸曲面，第一侧面233朝向叶轮3的转动轴线X，第二侧面234背向叶轮3的转动轴线X。
在本实施例中，叶轮3有部分位于蜗壳1与蜗舌2之间的空间中，第一导流件23被设置于蜗舌2附近的叶片内缘附近，第一导流件23与蜗舌2之间的距离小于第一导流件23与蜗壳1之间的距离。
在本实施例中，第一导流件23与叶轮的多个叶片5之间的最近距离D1约为4毫米，第一导流件23与转动轴线X之间的距离D2约为30毫米，叶片5与转动轴线X之间的距离D3约为40毫米。
从图5中容易看出，第一导流件23被设置于叶轮3的内部空腔4中，由于第一导流件23不会跟随叶轮3进行转动，当叶轮3在电机6的驱动下进行转动工作时，第一导流件23可以有效阻止气流在蜗舌2附近形成偏心涡，并防止或减少从叶轮3排出的气体再回流到叶轮3内，因此本发明的贯流风机能显著降低其噪音并提高其效率。
图7至图10示出了本发明第二个实施例的贯流风机。从图7至图10中可以看到，本实施例的贯流风机与图1至图6所示的第一个实施例的贯流风机相似，只是叶轮3和导流装置20的结构有所不同。
本实施例的叶轮3是在第一个实施例的叶轮的基础上增加了一块支撑板26，以提高整个叶轮的强度；本实施例的导流装置20包括两个第一导流件23和将两个第一导流件23连接在一起的连接装置，该连接装置包括连杆28和固定于连杆28两端的两个圆形支撑板27，这样可以增加导流装置20的整体强度，并能与本实施例的叶轮相匹配；另外本实施例的第一导流件23的形状也有所不同，本实施例的第一导流件23的第一侧面233为外凸曲面，而在第一个实施例中，第一导流件的第一侧面为平面。
从图10中也容易看出，本实施例的第一导流件23也可以有效阻止气流在蜗舌2附近形成偏心涡，并防止或减少从叶轮3排出的气体再回流到叶轮3内，因此也能显著降低贯流风机的噪音并提高贯流风机的效率。
图11至图13示出了本发明第三个实施例的贯流风机。从图11至图13中可以看到，本实施例的贯流风机与图1至图6所示的第一个实施例的贯流风机也相似，只是导流装置20的结构有所不同。
本实施例的导流装置20是在第一个实施例的导流装置的基础上增加了第二导流件24，其中，第二导流件24与第一导流件23相隔一定的距离。
从图13中容易看出，位于叶轮3内部的第一导流件23和第二导流件24也能有效阻止气流在蜗舌2附近形成偏心涡，并防止或减少从叶轮3排出的气体再回流到叶轮3内，因此也能显著降低贯流风机的噪音并提高贯流风机的效率。
很显然，人们可以根据实际需要来增加设置在叶轮内部的导流件的数量。
事实上，上述三个实施例的贯流风机都可以被应用到风扇或空调器中，使相应的风扇或空调器能降低噪音并提高效率。
尽管已经展示和描述了目前认为是优选的本发明的实施例，但显而易见，本领域的技术人员可以进行各种改变和改进，而不背离由所附权利要求书所限定的本发明的范围。
