例如，中国专利申请201210332506.3号揭示一种多电机吸尘器，其包括收集桶，收集桶上部设有机头组件，机头组件包括托盘，托盘上部设有电机座，电机座上设有容纳电机的电机腔，电机具有第一进风口，所述电机置于电机腔，所述电机腔上设有第二进风口，第一进风口和第二进风口之间设有风道控制组件，风道控制组件可控制第二进风口的打开或关闭。风道控制组件包括控制阀，控制阀为单向阀、伞阀和翻转阀。
中国专利申请201210332506.3号的多电机吸尘器，多个电机的正下方分别设有一风道控制组件，多个风道控制组件以一定距离间隔而设。当多个电机中部分电机开启而部分电机关闭时，开启状态下的电机所对应的风道控制组件被开启，关闭状态下的电机所对应的风道控制组件未打开，部分气流从托盘口进入，先绕路经过未打开风道控制组件，由于未打开风道控制组件所对应的第二进风口处于关闭状态，绕路后的气流会流向已开启风道控制组件所对应的第二进风口，再进入第一进风口。
中国专利申请201210332506.3号的多电机吸尘器，多个风道控制组件分别 设置于多个电机与电机座之间，且多个风道控制组件以一定距离间隔而设，托盘口与未打开风道控制组件之间的距离形成第一气流绕路距离，未打开风道控制组件与已未打开风道控制组件之间的距离形成第二气流绕路距离，第一气流绕路距离与第二气流绕路距离的叠加导致气流绕路的路径较长，则会影响风速和流量。

可选地，所述转轴的一端设有第一防呆部，所述连接部设有第二防呆部，所述第二防呆部与所述第一防呆部配合。

请参阅图1-图5所示，本实用新型提供一种多电机吸尘器，其包括集尘桶、盖设于所述集尘桶上的机头组件1和连接于所述机头组件下方的过滤组件(图未示)；所述机头组件1包括：
若干电机10，其用于提供吸力；可根据需要设置电机10的数量，电机10的数量包括二个及二个以上。
托盘20，其包括总进风口21与若干分进风口22，各所述分进风口22分别与所述电机10连通；所述总进风口21与过滤组件连通并用以提供过滤后的气流通过；可根据电机10的数量设置分进风口22的数量，分进风口22的数量包括二个及二个以上；未绕路气流经总进风口21、已打开分进风口22再流入电机；绕路气流经总进风口21、未打开分进风口22、已打开分进风口22再流入电机；可通过设置分进风口22与总进风口21的距离以控制气流绕路的路径，分进风口22与总进风口21的距离越小，气流绕路(总进风口21与未打开分进风口22之间)的路径越小，因气流绕路发生的损耗越小。
若干控制阀30，所述控制阀30的数量与所述分进风口的数量一致，各所述控制阀30连接于所述托盘20上并分别盖设于对应的所述分进风口22上，所述控制阀30包括打开状态与关闭状态以控制所对应的分进风口22的打开与关闭；可根据分进风口22的数量设置控制阀30的数量，控制阀30的数量包括二个及二个以上。
电机座40，其用于承载所述电机10，所述电机座40与托盘20共同分隔形成若干独立的分气流通道，所述分气流通道用以提供气流从分进风口22进入所述电机10。
盖体50，其盖设于所述电机座40上并与所述集尘桶密封连接。
在本实用新型的一个实施例中，所述托盘20跨设有连接部23，所述控制阀30为转轴门扇式单向阀，所述控制阀30包括转轴31与连接于转轴31上的门扇式阀面，门扇式阀面上远离转轴31的外侧称之为自由端。所述控制阀30通过转轴31连接于所述连接部23上并相对于所述托盘20旋转，所述控制阀30在关闭状态聚拢收合于所述总进风口21的上方。所述连接部23设置于托盘20的中部，多个控制阀30通过连接部23共同设置于托盘20内，多个控制阀30的转轴31之间的距离与连接部23的壁厚相关，可通过设置连接部23的壁厚以控制多个控制阀30的转轴31之间的距离；控制阀30的转轴31之间的距离越小，气流绕路(未打开分进风口与已打开分进风口之间)的路径越小，因气流绕路发生的损耗越小。可通过设置所述控制阀30聚拢收合的角度以控制多个控制阀30的自由端在关闭状态下的距离，多个关闭状态下的控制阀30的自由端之间的距离越小，气流绕路(未打开分进风口与已打开分进风口之间)的路径越小，因气流绕路发生的损耗越小。
在本实用新型的一个实施例中，所述托盘20内侧设有分隔壁24，所述分隔壁24与所述连接部23形成分进风口22。通过设置分隔壁24的高度以控制关闭状态下的控制阀30的阀面与进入至分进风口22的气流方向的夹角，气流方向的夹角越靠近90度，则控制阀30越容易被打开。将控制阀30的阀面与进入至分进风口22的气流方向的夹角在70度～110度的情形，称之为所述控制 阀30的阀面与进入至分进风口22的气流方向直面相对(如图12中的箭头指示气流方向)。
在本实用新型的一个实施例中，所述转轴31的一端设有第一防呆部32，所述连接部23设有第二防呆部25，所述第二防呆部25与所述第一防呆部32配合。
在本实用新型的一个实施例中，所述控制阀30上靠近总进风口的一面设有若干导向筋35，所述导向筋35之间平行且间隔而设。
在存在导向筋35的设计中再加以防呆设计，以确保控制阀30的正确安装，安装后的控制阀30，设有导向筋35的一面与总进风口21相对，从而使得控制阀30被打开后，所述控制阀30的阀面的倾斜方向与进入至分进风口22的气流方向顺向，导向筋35的延伸方向与进入至分进风口22的气流方向顺向，通过导向筋35的引导作用，气流更为顺畅的流入至电机。控制阀30的阀面的倾斜方向与进入至分进风口22的气流方向接近平行(例如夹角在20度以内)称之为顺向。
在本实用新型的一个实施例中，所述控制阀30在打开状态下，所述控制阀30的阀面的倾斜方向与进入至分进风口22的气流方向顺向。
在本实用新型的一个实施例中，所述控制阀30在关闭状态下，所述控制阀30的阀面与进入至分进风口22的气流方向直面相对。
请参阅图4、图6与图7所示，在本实用新型的一个实施例中，所述电机座40上设有导风腔41，导风腔41偏向分进风口22，导风腔41的偏置方向与气流方向顺向。
在本实用新型的一个实施例中，所述电机座40上与托盘20相对的一侧设 有若干限位部42，当所述控制阀30的转轴31旋转时，所述限位部42上靠近转轴31的区域压靠转轴31，所述限位部42上远离转轴31的区域抵持打开状态下的控制阀30(如图10所示)。
请参阅图9所示，在本实用新型的一个实施例中，所述托盘20上设有抵接筋241，所述抵接筋241可设置于分隔壁24的上缘，抵接筋241在分隔壁24上形成尖细的端部，有利于形成线密封，所述控制阀30的外缘设有弹性密封体36，所述抵接筋241与所述弹性密封体36抵持配合以形成线密封，且所述抵接筋241的延伸方向垂直于所述弹性密封体36。通过尖细的抵接筋241沿垂直方向陷入弹性密封体36，密封效果更好。抵接筋241的高宽比按尖细要求设置，例如宽度0.5mm，高度0.5mm。在抵接筋241高度一定的条件下，抵接筋241的宽度越小，密封效果越好。
请参阅图2、4、8-12所示，在本实用新型的一个实施例中，包括双电机的机头组件1包括：
第一电机11与第二电机12，其用于提供吸力；
托盘20，其包括总进风口21、第一分进风口221与第二分进风口222，第一分进风口221与第一电机11连通，第二分进风口222与第二电机12连通；

电机座40，其用于承载第一电机11与第二电机12，所述电机座40与托盘 20共同分隔形成第一分气流通道与第二分气流通道，第一分气流通道用以提供气流从第一分进风口221进入第一电机11；第二分气流通道用以提供气流从第二分进风口222进入第二电机，且所述电机座40上设有第一导风腔411与第二导风腔412，第一导风腔411偏向第一分进风口221，第二导风腔412偏向第二分进风口222，第一导风腔411与第二导风腔412的偏置方向与气流方向顺向；
盖体50，其盖设于所述电机座40上并与所述集尘桶密封连接。
请参阅图4与图8所示，当第一电机11与第二电机均12关闭时，第一控制阀301与第二控制阀302保持关闭。
请参阅图4与图10所示，当第一电机11开启而第二电机12关闭时，第一控制阀301因负压而打开以使第一分进风口221被打开，外部进入的气流经总进风口21、第一分进风口221、第一导风腔411后流入第一电机11，第二控制阀302保持关闭。
请参阅图4与图11所示，当第二电机12开启而第一电机11关闭时，第二控制阀302因负压而打开以使第二分进风口222被打开，外部进入的气流经总进风口21、第二分进风口222、第二导风腔412后流入第二电机12，第一控制阀301保持关闭。
请参阅图4与图12所示，当第一电机11开启且第二电机12开启时，第一控制阀301因负压而打开以使第一分进风口221被打开，外部进入的部分气流经总进风口21、第一分进风口221、第一导风腔411后流入第一电机11；第二控制阀302因负压而打开以使第二分进风口222被打开，外部进入的部分气流经总进风口21、第二分进风口222、第二导风腔412后流入第二电机12。
本实用新型多电机吸尘器的部分电机已开启而部分电机未开启时，已开启 电机所对应的控制阀因负压被打开，而未开启电机所对应的控制阀保持关闭，部分气流经总进风口、分进风口(已打开控制阀所对应的)后流入电机，另一部分气流经总进风口、未打开控制阀、分进风口(已打开控制阀所对应的)后流入电机，由于控制阀连接于托盘上，可减少气流绕路的路径，形成顺畅的分气流通道，实现增大风速和流量，减少能量损耗。另，将多个控制阀共同设置于连接部上且聚拢设置，可进一步减少气流绕路的路径，实现增大风速和流量，减少能量损耗。
