具体实施方式
为使本公开的上述目的、特征和优点能够更为明显易懂，下面结合附图对本公开的具体实施例做详细的说明。
实施例一
本发明实施例一提供了一种贯流风叶1，如图1-10所示，所述贯流风叶1包括风叶本体2和两个风叶端板3，4。所述风叶本体2呈圆柱状，包括多个叶片5。所述两个风叶端板3，4具体为第一风叶端板3和第二风叶端板4，二者均为圆板，分别设置在所述风叶本体2的两端，其中，第一风叶端板3包括轴盘6和轴孔7，所述轴孔7位于所述轴盘6中心；所述第二风叶端板4包括轴盘8和轴9，所述轴9位于所述轴盘8中心，且与所述轴盘垂直。所述轴盘的边缘圆周上设置有多个开口10，所述多个叶片5的端部分别伸入所 述多个开口10中。
所述贯流风叶1的一端(第一风叶端板3所在端)用于与驱动电机连接，另一端(第二风叶端板4所在端)用于与轴承固定座11连接。所述贯流风叶1具有两端面12，13(端面12即贯流风叶的第一风叶端板所在面，端面13即贯流风叶的第二风叶端板所在面)，在其中一端面上设有凹槽14。具体的，所述贯流风叶1与所述轴承固定座11连接的一端的端面13上设有凹槽14，该一端的端面为凹槽型端面，相应的，所述贯流风叶1的所述第二风叶端板4上设有凹槽14，以防止水流顺着风叶端面13进入轴承固定座11，腐蚀轴承胶圈，影响性能和使用寿命，避免在空调器运行时产生大量噪音，影响用户体验。
更具体而言，在所述第二风叶端板4的轴盘8上设置所述凹槽14，所述凹槽14呈环形，环绕所述轴9，且所述凹槽14的轴线与所述第二风叶端板4的轴盘8的轴线重合，所述轴9的延伸方向与所述轴线方向相同。
进一步的，本实施例一还提供了一种风机组件，请继续参照图1-10所示，所述风机组件包括所述贯流风叶1，还包括驱动电机、轴承固定座11和底座17；其中，所述驱动电机的转轴与所述第一风叶端板3的轴孔7连接，用于驱动所述贯流风叶1旋转；所述轴承固定座11与所述第二风叶端板4的轴9连接，用于使所述贯流风叶1保持平稳。
具体的，所述轴承固定座11包括圆筒状壳体15，所述圆筒状壳体15为中空结构，在圆筒状壳体15与所述贯流风叶1连接的一端设有开口16，在圆筒状壳体15的内部设置有轴承胶圈。所述圆筒状壳体15的所述一端伸入所述贯流风叶1的所述凹槽14内，且所述轴从所述圆筒状壳体15的所述开口16伸入所述圆筒状壳体15内。为了在保证防水效果的同时保证风叶强度及风量，所述轴承固定座11伸入所述凹槽14的深度d介于5-15mm之间，也即所述圆筒状外壳与所述凹槽14的重合长度介于5-15mm之间，以10mm为佳；若重合长度过短，则防水效果较差，若重合长度过长，则会影响风叶强度及风量。
所述轴承固定座11与所述凹槽14之间的配合间隙s介于2-10mm之间，也即所述轴承固定座11的圆筒状壳体15与所述凹槽14靠外侧的侧壁之间的距离介于2-10mm之间，以5mm为佳。
可选的，所述凹槽14为圆弧型平滑凹槽，通过采用圆弧平滑设计，可有效的减小应力、减小噪音。
本实施例风机组件通过采用端面具有凹槽14的贯流风叶1，轴承固定座11的一端部伸入所述凹槽14中，从而防止水流进入轴承固定座11内。
实施例二
本实施例二提供了一种轴承固定座11，如图11-13所示，所述轴承固定座11包括圆筒状壳体15，所述圆筒状壳体15为中空结构，在所述圆筒状壳体15与贯流风叶1连接的一端具有开口16，在所述圆筒状壳体15的内部设置有轴承胶圈。
所述轴承固定座11具有相对的两端部，在其中一端部上设有挡水板18，具体是在所述轴承固定座11的圆筒状壳体15与贯流风叶1连接的一端设置有挡水板18，所述挡水板18为环形挡水板，围绕所述圆筒状壳体15一圈。所述挡水板18由所述圆筒状壳体15的侧壁向所述圆筒状壳体15的轴线方向延伸，形成向内弯折的折边。所述环形挡水板的外侧与所述圆筒状壳体15连接，内侧形成所述开口16。通过在所述轴承固定座11与贯流风叶1连接的一端设置挡水板18，可避免水流沿轴承固定座11的圆筒状壳体外侧进入轴承固定座11内部造成腐蚀，影响性能和使用寿命。
所述挡水板18与所述圆筒状壳体的端面之间的角度θ介于10°-30°之间，以15°为佳，由此，可以更有效的防止水流直接进入所述轴承固定座内部。若角度过小，水会沿着边沿流下，防水效果不够理想；此外，在挡水板18长度一定情况下，角度越大，挡水板18伸出的长度越大，占用空间越大，若角度过大，会导致占用空间较大。
进一步的，本实施例二还提供了一种风机组件，请继续参照图11-13所示，所述风机组件包括所述轴承固定座11，还包括贯流风叶1和驱动电机。其中，所述驱动电机与所述贯流风叶1的一端连接，用于驱动所述贯流风叶1旋转；所述轴承固定座11与所述贯流风叶1的另一端连接(具体是所述轴承固定座11的设置挡水板18的一端与所述贯流风叶连接)，用于使所述贯流风叶1保持平稳。
具体的，所述贯流风叶1包括风叶本体和两个风叶端板。所述风叶本体呈圆柱状，包括多个叶片。所述两个风叶端板具体为第一风叶端板和第二风 叶端板，分别设置在所述风叶本体的两端，其中，第一风叶端板包括轴盘和轴孔，所述轴孔位于所述轴盘中心；第二风叶端板包括轴盘和轴，所述轴位于所述轴盘中心，且与所述轴盘垂直。所述轴盘的边缘圆周上设置有多个开口，所述多个叶片的端部分别伸入所述多个开口中。
所述驱动电机的转轴与所述第一风叶端板的轴孔连接；所述轴承固定座11与所述第二风叶端板的轴连接。

所述疏水槽19为环形疏水槽，围绕所述圆筒状壳体15一圈，疏水槽19轴向与圆筒状壳体15的轴向相同。所述疏水槽19的深度p介于0.5-1.5mm之间，宽度q介于0.5-1.5mm之间；可选深度p为1mm，宽度q为1mm。
此外，可以在所述外侧壁上同时设置多个疏水槽19，多个疏水槽可在所述圆筒状壳体15上间隔分布，以提高防水效果。
进一步的，本实施例三还提供了一种风机组件，请继续参照图14-16所示，所述风机组件包括所述轴承固定座11，还包括贯流风叶1和驱动电机。其中，所述驱动电机与所述贯流风叶1的一端连接，用于驱动所述贯流风叶1旋转；所述轴承固定座11与所述贯流风叶1的另一端连接(具体是所述轴承固定座11的设置疏水槽19的一端与所述贯流风叶连接)，用于使所述贯 流风叶1保持平稳。
具体的，所述贯流风叶1包括风叶本体和两个风叶端板。所述风叶本体呈圆柱状，包括多个叶片。所述两个风叶端板包括第一风叶端板和第二风叶端板，分别设置在所述风叶本体的两端，其中，第一风叶端板包括轴盘和轴孔，所述轴孔位于所述轴盘中心；第二风叶端板包括轴盘和轴，所述轴位于所述轴盘中心，且与所述轴盘垂直。所述轴盘的边缘圆周上设置有多个开口，所述多个叶片的端部分别伸入所述多个开口中。所述驱动电机的转轴与所述第一风叶端板的轴孔连接；所述轴承固定座11与所述第二风叶端板的轴连接。

所述贯流风叶1包括两端面12、13，在其中一端面上设有挡水筋20，也就是在所述贯流风叶1与轴承固定座11连接的一端的端面上设置有挡水筋20，当水流下时，所述挡水筋20可有效阻止水流进入轴承固定座11内，避免造成腐蚀，影响性能和使用寿命。
