Description

电机、送风装置和家用电器
本申请要求于2019年08月23日提交中国国家知识产权局、申请号为“2019107867015”、申请名称为“电机、送风装置和家用电器”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及电机技术领域，具体而言，涉及一种电机、一种送风装置和一种家用电器。
背景技术
目前，常用的风扇电机由内外相互套设的定子和转子构成，在电机对外驱动时，通过定子驱动转子进而带动电机的转轴转动实现扇叶或其他负载的运转，其中，定子和转子同轴设置，且需在周向方向形成封闭结构，转轴会沿轴向向外伸出，从而使得由于电机自身的结构的限制，会增加整个产品在轴向方向上的尺寸，同时定子与转子的相互位置不灵活，不利于产品的轻量化设计。
发明内容
本申请旨在至少解决现有技术或相关技术中存在的技术问题之一。
为此，本申请的一个目的在于提供一种电机。
本申请的另一个目的在于提供一种送风装置。
本申请的再一个目的在于提供一种家用电器。
为了实现上述目的，本申请的第一方面技术方案提供了一种电机，包括：转子结构；定子结构，与转子结构可拆卸连接，定子结构设于转子结构沿径向方向的内侧，用于驱动转子结构转动。
根据本申请的第一方面技术方案中的电机，包括转子结构和定子结构，取消了传统电机的驱动轴，形成无芯电机，改变了电机与负载的设置方式，使电机无需与负载沿轴向设置，从而可减小电机在轴向方向上的尺寸，有效降低对空间的占用，有利于实现轻量化和小型化的设计。此外，定子结构设于转子结 构沿径向方向的内侧，改变了现有传统电机中定子的结构的设置位置，即定子结构无需在转子结构内或外沿周向形成环状封闭结构或对称结构，仅需设置于转子结构沿径向方向的内侧即可驱动转子结构转动，从而带动负载运动；同时，通过对定子结构的设置位置的改进还可进一步减小电机的整体体积和重量，尤其可以缩减电机的轴向方向的空间占用，例如在风扇中使用本申请的电机，可取消扇叶后方的电机安装位，有利于实现风扇的扁平化和轻量化，减小风扇机头部分的重量以及偏心影响，减少不必要的配重设置，有利于提高整体稳定性。
其中，由于定子结构和转子结构之间可拆卸，故而在应用上述电机驱动负载运动时，可单独将负载连同转子结构一起拆下进行清洗或更换，便于操作。
需要强调的是，定子结构根据转子结构的设置位置对应设置于转子结构的内侧，一方面使电机整体形成偏心结构，定子结构的设置位置更加灵活，使得电机可适用于多种不同结构的负载，另一方面定子结构隐藏设置于转子结构内，减少电机整体的空间占据，对于电机整体而言，外边界仅为转子结构所围成的区域，定子结构并不占据额外的空间，还可进一步缩减电机整体沿径向方向的尺寸。
其中，转子结构整体可以为圆环状、方形环状、椭圆环状或其它封闭环状。
另外，本申请提供的上述技术方案中的电机还可以具有如下附加技术特征：
在上述技术方案中，电机包括驱动区，驱动区包括至少一个定子铁芯，及转子结构中与定子结构正对部分。
在该技术方案中，电机包括驱动区，进一步地，驱动区包括至少一个定子铁芯以及转子结构中与定子结构正对的部分，即通过驱动区中定子铁芯对转子结构与定子铁芯正对的部分产生驱动力，驱动转子结构转动。其中，由于定子铁芯的位置固定，在转子结构的转动时，在驱动区中与定子结构正对的转子结构的部分随之改变，但转子结构整体所受到的切向驱动力不变，进而驱动转子结构持续进行转动，实现电机的运行。
其中，驱动区的数量可以为一个，也可以为多个。
在上述技术方案中，定子结构具有第一曲面，第一曲面朝向转子结构，第一曲面为弧形，转子结构呈圆环形，至少部分定子结构朝向转子结构的侧面的 曲率与转子结构的曲率相同。
在该技术方案中，通过限定转子结构呈圆环形，定子结构具有朝向转子结构弧形的第一曲面，且至少部分第一曲面的曲率与转子结构的曲率相同，以使至少部分第一曲面与转子结构形成等间距，从而使至少部分定子结构对转子结构形成的驱动力保持均衡，有利于提高转子结构转动过程中的稳定性。
可以理解，第一曲面的至少部分弧面与转子结构的弧面相平行。
在上述技术方案中，第一曲面为圆弧形，转子结构呈圆环形，第一曲面的曲率与转子结构的曲率相同。
在该技术方案中，通过限定转子结构呈圆环形，第一曲面为圆弧形，且第一曲面的曲率与转子结构的曲率相同，使得定子结构整体与转子结构形成等间距设置，从而使定子结构对转子结构形成的驱动力在转子结构转动过程中始终保持恒定，可进一步提高转子结构转动过程的稳定性。可以理解，若定子结构对转子结构的驱动力大小发生变化，容易造成转子结构转动速率的改变，影响转子结构的转动稳定性。
其中，第一曲面的弧面与转子结构的弧面始终平行。
在上述技术方案中，转子结构与定子结构的最大距离不大于4mm。
通过设定转子结构与定子结构的最大距离不大于4mm，既可满足转子结构与定子结构之间保持间隙，以防止定子结构对转子结构的转动产生干涉，又可以使得定子结构对转子结构产生的驱动力尽可能大，从而提高转子结构的转动效率。
进一步地，定子结构和转子结构之间不设置遮挡物时的驱动效果最佳。
在上述技术方案中，转子结构具体包括至少一个磁性件。
在该技术方案中，转子结构包括至少一个磁性件，通过与磁性件对应设置的定子铁芯上的定子绕组的磁场，对磁性件产生作用力，且多个磁性件所受到的作用力方向相同，从而驱动磁性件转动，实现负载的运动。可以理解，磁性件沿周向的长度越长，受到定子结构的磁力作用时间越长，即使转子结构仅包括一个磁性件，只要磁性件沿周向的长度足够长，仍能够在定子结构在作用下实现持续转动。
在上述技术方案中，定子结构包括设于至少一个定子铁芯上且朝向转子结 构设置的至少两个定子齿。
在该技术方案中，定子铁芯上设有定子齿，通过限定至少一个定子铁芯上朝向转子结构设置有至少两个设有定子绕组的定子齿，以通过两个定子齿形成对转子结构的磁场作用力，驱动转子结构发生转动，进而带动负载运行。
其中，可以理解，定子结构包括至少两个定子齿，至少两个定子齿可以设于一个定子铁芯上，或设于多个定子铁芯上，即定子铁芯的数量为一个或多个，所有定子铁芯上的定子齿的总数至少为两个。
在上述技术方案中，定子齿的数量至少为两个，任意两个定子齿上的定子绕组依次通电且极性相同；或定子齿的数量至少为两个，任意两个定子齿上的定子绕组同时通电且极性不同，并且，任意两个定子齿上的定子绕组的磁极交替。
在该技术方案中，定子铁芯上设有定子齿，通过限定定子铁芯上的定子齿的数量为至少两个，通过对任意两个定子齿上的定子绕组依次通电且极性相同，可使转子结构依次受到两个定子齿上的定子绕组的作用，产生同一方向的作用力，使转子结构向同一方向持续转动；此外，也可以对任意两个定子齿上定子绕组同时通电且极性不同，通过任意两个定子齿上的定子绕组的磁极交替，对转子结构产生相同方向的持续的作用力，驱动转子结构向同一方向持续转动。
可以理解，至少两个定子齿可以设于同一个定子铁芯，也可以设于不同的定子铁芯上。
在上述技术方案中，每个定子齿的定子齿靴的端面沿转子结构的径向设置，且定子齿靴的端面沿转子结构的径向方向远离转子结构的旋转轴设置。
在该技术方案中，通过限定每个定子齿的定子齿靴的端面沿转子结构的径向设置，且定子齿靴的端面沿转子结构的径向方向远离转子结构的旋转轴设置，以使每个定子齿与转子结构对应设置，从而使每个定子铁芯均可对转子结构产生沿切向方向的作用力，以驱动转子结构沿相同方向转动。
在上述技术方案中，定子结构包括具有三个定子齿的定子铁芯，三个定子齿的定子齿靴的端面距转子结构的旋转中心的距离均相等，其中，三个定子齿的定子齿靴的端面形成外凸的弧线形状。
在该技术方案中，通过限定定子结构包括三个定子齿的定子铁芯，且三个定子齿的定子齿靴的端面距转子结构的旋转中心的距离均相等，使转子结构的旋转中心与每个定子齿的定子齿靴的端面保持相同的间距，以确保转子结构在转动过程中所受到的磁场作用力的大小保持均衡，从而提高电机运转过程中的稳定性。
其中，限定三个定子齿的定子齿靴的端面形成外凸的弧线形状，以使定子齿靴的端面与转子结构的圆环形状相适配，以免定子齿靴与设于负载上的转子结构发生干涉。
其中，具有三个定子齿的定子铁芯的数量可以为一个，也可以为多个，多个定子铁芯可以均布设置，也可以非对称设置。
在上述技术方案中，定子齿的数量至少为三个，且任意两个定子齿上的定子绕组依次通电且极性相同；或定子齿的数量至少为三个，且任意两个定子齿上的定子绕组同时通电且极性不同，并且，任意两个定子齿上的定子绕组的磁极交替。
在该技术方案中，通过限定定子铁芯上的定子齿的数量为至少三个，通过对任意两个定子齿上的定子绕组依次通电且极性相同，可使转子结构依次受到两个定子齿上的定子绕组的作用，产生同一方向的作用力，使转子结构向同一方向持续转动；此外，也可以对任意两个定子齿上定子绕组同时通电且极性不同，通过两个定子齿上的定子绕组的磁极交替，对转子结构产生相同方向的持续的作用力，驱动转子结构向同一方向持续转动。
例如，定子结构的定子齿的数量为三个，对三个定子绕组中相邻的两个同时通电，进一步地，先对第一定子绕组和第二定子绕组通电，再对第二定子绕组和第三定子绕组通电，其中，第一定子绕组产生N极磁场对转子结构中磁性件的S极吸引，第二定子绕组产生S极磁场对转子结构中磁性件的N极吸引，对转子结构整体形成一个切向的作用力，然后，对第二定子绕组和第三定子绕组通电，第二定子绕组产生N极磁场对磁性件的N极排斥，第三定子绕组产生S极磁场对磁性件的S极排斥，使转子组件继续转动，依此循环，使转子组件不断旋转。
特别地，本申请的电机通过调整三个定子绕组的通电顺序，还可实现 反向运行，简言之，先对第三定子绕组和第二定子绕组通电，而后对第二定子绕组和第一定子绕组通电即可实现反向旋转。
在上述技术方案中，电机还包括一个磁性判断装置，磁性判断装置沿转子结构的周向设置，用于获取转子结构相对于定子结构的转动方向。
在该技术方案中，通过演转子结构的周向设置的磁性判断装置，用于获取转子结构相对于定子结构的转动方向，以使转子结构沿某一确定的方向进行转动，例如顺时针转动或逆时针转动。
其中，磁性判断装置可以为霍尔元件，还可以为其它用于检测磁性的传感器，以确定转子结构的转动方向，减少出现停转或反转等转动异常的情况发生。
进一步地，在定子结构包括两个定子齿时，可通过对两个定子齿上的绕组分别通电或同时通电实现对转子结构的驱动，进一步地，在分别通电时，第一定子绕组先通N极，吸引转子结构上S极的磁性件向第一定子绕组移动，此时第二定子绕组对应的磁性件的极性为N极，随后，第二定子绕组通N极，通过排斥力驱动转子旋转，两个定子绕组依次通电即可实现转动；在同时通电时，两个定子绕组通电后的磁极相反，例如第一次通电，两个定子绕组的磁极分别为N-S，等转子转动至对应位置时，再调整定子绕组的磁极为S-N，从而对当前转子产生斥力，形成转动。
在上述技术方案中，定子铁芯的数量为多个，多个定子铁芯沿转子结构的周向设置。
在该技术方案中，通过限定多个定子铁芯沿转子结构的周向设置，且每个定子铁芯上设有至少一个定子齿，以使与定子结构相对应的转子结构部分与定子结构之间的距离保持一致，有利于转子结构在径向方向的受力均衡。进一步地，在多个定子铁芯沿转子结构的周向均匀设置时，有助于转子结构在周向方向的受力均衡，减轻了转子组件在转动过程中产生的振动，以保持转子结构转动过程中的稳定性，进而减小了电机在工作过程中产生的噪音，延长了电机的使用寿命。此外，增加定子齿的数量，可以增大定子结构整体的磁场作用力，从而加快转子结构的转动速率，因此，可根据负载的转速需求，设置相应数量的定子齿，从而扩大电机的使用范围。
在上述技术方案中，电机还包括：支撑结构，转子结构可转动地设于支撑结构上。
在该技术方案中，通过将转子结构可转动地设于支撑结构上，以通过支撑结构限制转子结构的径向位移或轴向位移，使得转子结构在定子结构的磁力作用下转动时的轴线不发生偏移，从而对负载进行稳定的动力输出，有利于保持电机的稳定性。可以理解，定子结构设于转子结构的一侧，转子结构整体的受力并不平衡，需要支撑结构对转子结构进行限位。

可以理解，转子结构收到定子结构的磁力作用后会产生沿切向方向的力，以驱动转子结构带动扇叶转动，若转子结构过于靠近扇叶的旋转中心，会造成扇叶的受力点的力臂缩短，在同样的磁力作用下，做功下降，导致扇叶的转动效率降低。

进一步地，扇叶还包括：第二风叶支架，与第一风叶支架同轴设置，且第二风叶支架套设于第一风叶外。
在该技术方案中，通过在第一风叶外设有与第一风叶支架同轴的第二风叶支架，使得第一风叶可通过内侧的第一风叶支架以及外侧的第二风叶支架同时进行固定，有利于提高扇叶转动时的稳定性和使用寿命。

在该技术方案中，通过在扇叶的外侧壁面上沿周向设有多个第二风叶，可使扇叶形成内外两圈风叶，从而增大气流。需要说明的是，第一风叶和第二风叶可以是相同形态的风叶，也可以是不同形态的风叶，例如第一风叶与第二风叶的形状不同，或者尺寸不同，或者倾斜角度不同。此外，通过设于扇叶内外两圈的多个第一风叶和多个第二风叶，还有利于对经过扇叶送出的气流的扩散运动，使得气流更加柔和，有利于提高送风装置的送风舒适度。
在上述技术方案中，转子结构设于第一风叶支架的内侧壁面上；和/或转子结构设于第二风叶支架的内侧壁面上。
在该技术方案中，扇叶结构包括同轴设置的第一风叶支架和第二风叶支架，第一风叶支架设于第二风叶支架的内侧，此时，转子结构可以设于第一风叶支架的内侧壁面，可以缩减转子结构与定子结构之间的间距，有利于增强磁力作用，增大驱动力；转子结构也可以设于第二风叶支架的内侧壁面，有利于延长扇叶受力的力臂，提高转动效率。当然，也可以在第一风叶支架的内侧壁面和第二风叶支架的内侧壁面上同时设有转子结构，以通过多个转子结构进一步增大定子结构对转子结构的驱动力。
在上述技术方案中，送风装置还包括：可拆卸连接的第一风罩和第二风罩，第二风罩与第一风罩连接后内部形成至少可容置转子结构的容纳空腔，其中，定子结构设于容纳空腔内，和/或定子结构设于容纳空腔外。
在该技术方案中，送风装置还包括第一风罩和第二风罩，通过第一风罩与第二风罩可拆卸地连接后内部形成容纳空腔，转子结构随扇叶一同容置于容纳空腔内，定子结构可以对应设于多个位置，其中，定子结构设于容纳空腔内时，可使电机整体置于容纳空腔内，通过第一风罩与第二风罩对电机以及扇叶起到保护作用，以免在电机驱动扇叶转动过程中与外界物体发生干涉；定子结构设于容纳空腔外时，有利于减小空间占用，便于定子结构的拆装；在定子结构包括多个定子铁芯时，也可以同时在容纳空腔内和外设有定子铁芯。此外，通过第一风罩与第二风罩可拆卸，以便对电机以及扇叶进行维护或清洗。
在上述技术方案中，电机的支撑结构设于第一风罩朝向第二风罩的一侧。
在该技术方案中，通过将支撑结构设于第一风罩朝向第二风罩的一侧，即支撑结构设于第一风罩上，且在第一风罩与第二风罩连接后支撑结构处于容纳空间内，通过支撑结构对设有转子结构的扇叶进行支撑，以防止扇叶在转动过程中发生偏移。
在上述技术方案中，第一风罩和/或第二风罩上设有通风格栅。
在该技术方案中，通过在第一风罩和/或第二风罩上设有通风格栅，以在扇叶转动时，使气流穿过第一风罩和/或第二风罩上的通风格栅进行流动，以实现送风装置的送风运行。进一步地，通风格栅可以沿扇叶的轴向方向设置，也可以同时沿扇叶的轴向方向和径向方向设置。
在上述技术方案中，电机的支撑结构呈空心轴状，扇叶套设于支撑结构上。
在该技术方案中，通过设置支撑结构呈空心轴状，扇叶套设于支撑结构上，以在通过电机驱动扇叶转动的过程中，支撑结构的空心结构可形成过风通道，以使空气能够由扇叶的一端通过过风通道流向另一端，从而增大送风装置的出风气流，有利于保持出风气流的稳定性。可以理解，在扇叶的转动轴的位置无过风通道时，会在局部对气流产生阻挡，送风装置出风侧的气流容易产生气旋，造成气流紊乱。
在上述技术方案中，电机的支撑结构呈实心轴状，送风装置还包括：轴套， 套设于支撑结构上，扇叶套设于轴套上。
在该技术方案中，电机的支撑结构呈实心轴状，通过在支撑结构上套设有轴套，且扇叶套设于轴套上，以通过轴套减小扇叶与支撑结构之间的摩擦力，从而降低扇叶的磨损，提高扇叶的转动效率，同时方便维修和更换，有利于降低使用成本。可以理解，若扇叶直接与支撑结构转动连接，则在磨损达到一定程度时需将扇叶进行整体更换，而扇叶通过轴套与支撑结构转动连接，仅需对轴套进行更换即可。
在上述技术方案中，送风装置还包括底座，定子结构设于底座上，且底座与扇叶可拆卸连接。
在该技术方案中，通过设有与扇叶可拆卸连接的底座，以便于送风装置的使用，以便在扇叶进行清洗维护；而定子结构设于底座上，即定子结构可与转子结构独立拆卸，也便于定子结构和转子结构分别进行清理和维护。可以理解，常用的电机的定子与转子通常为一体安装，无法对电机内部进行清理，内部附着的灰尘等杂质容易对电机的正常运转造成影响。

具体实施方式
为了能够更清楚地理解本申请的上述目的、特征和优点，下面结合附图和具体实施方式对本申请进行进一步的详细描述。需要说明的是，在不冲突的情况下，本申请的实施例及实施例中的特征可以相互组合。
在下面的描述中阐述了很多具体细节以便于充分理解本申请，但是，本申请还可以采用其他不同于在此描述的其他方式来实施，因此，本申请的保护范围并不受下面公开的具体实施例的限制。
本申请提供了一种送风装置2的实施例，其中，送风装置2包括有由定子 结构14和转子结构12组合形成偏心的电机1，以及直接与转子结构12相接触的扇叶22，其中，转子结构12包括多个形成封闭图形的磁性件122，定子结构14设于多个磁性件122所形成的环形结构的内侧、外侧、内端、外端中的一个或多个位置，在对定子结构14中绕设于定子齿144上的定子绕组的电流方向进行控制时，可产生不同极性的磁场，此时通过至少两个极性不同的定子绕组，可对转子结构12实现驱动，使得转子结构12带动负载实现转动。
进一步地，多个磁性件122合围形成环形，还进一步地，多个磁性件122之间存在间隙，形成间断的环形。
需要说明的是，偏心的电机1是指定子结构14处于转子结构12的一侧或一端，可以是轴向方向的一端，也可以是径向方向的一侧，以使定子结构14形成不连续的磁场。

下面参照图1至图10描述本申请一些实施例的电机和送风装置。
实施例一
如图1至图4所示，本申请的一个实施例提出了一种电机1，包括可拆卸连接的转子结构12和定子结构14。其中，转子结构12呈圆环形，定子结构14设于转子结构12的内侧且与转子结构12之间存在间隙，定子结构14包括至少一个沿转子结构12周向设置的定子铁芯142，以通过定子铁芯142对转子结构12形成驱动力，进而驱动转子结构12转动。电机1上设有驱动区，驱动区包括一个定子铁芯142以及转子结构12与定子结构14正对的部分，以在驱动区内的定子结构14与转子结构12相互作用，产生驱动转子结构12转动的驱动力；在驱动区中，定子结构14位置保持固定，转子结构12与定子结构14正对的部分随着转子结构12的转动而发生变化，但处于驱动区内的转子结构12与定子结构14正对的部分均受到相同的驱动力的作用，进而带动转子结构12沿相同方向持续转动。

进一步地，如图3所示，转子结构12与定子结构14之间的最大间隙h不大于4mm。
进一步地，转子结构12和定子结构14之间的间隙为1mm、2mm、3mm、4mm。
实施例二
本申请的另一个实施例提供了一种电机1，包括可拆卸连接的转子结构12和定子结构14，其中，转子结构12呈圆环形，定子结构14设于转子结构12的内侧且与转子结构12之间存在间隙，定子结构14包括至少一个沿转子结构12周向设置的定子铁芯142，以通过定子铁芯142对转子结构12形成驱动力，进而驱动转子结构12转动。如图2所示，定子结构14包括设有三个定子齿144的定子铁芯142，且在定子齿144上设有绕组，相邻的两个定子绕组的极性不同，通过对相邻的两个定子绕组同时通电，以使定子结构14产生磁场驱动转子结构12转动，进一步地，先对第一定子绕组和第二定子绕组通电，使第一定子绕组产生N极磁场对转子结构12中磁性件122的S极吸引，第二定子绕组产生S极磁场对转子结构12中磁性件122的N极吸引，从而形成对转子结构12整体形成切向方向的作用力，转子结构12在该作用力作用下转动一段距离后，再对第二定子绕组和第三定子绕组通电，使第二定子绕组产生N极磁场对磁性件122的N极排斥，第三定子绕组产生S极磁场对磁性件122的S极排斥，使转子组件继续转动，依此循环，使转子组件持续旋转。此外，通过改变三个定子绕组的通电顺序，还可实现转子结构12的反向转动。
进一步地，三个定子齿144的定子齿靴1442的端面均为圆弧面，且每个定子齿靴1442的端面距转子结构12的距离均相等。

进一步地，如图4所示，磁性件122为磁性片，且多个磁性片组成环形结构。

本实施例中，转子结构中的磁性件可以选择强磁类材料，以保证定子结构可通过间距h对转子结构产生驱动作用，可以理解，本实施例中二者的径向方向上存在扇叶，可选用对磁场影响较小的材料制成扇叶，以减少对定子结构的驱动的影响。
实施例五
本申请的另一个实施例提供了一种送风装置2，如图6所示，送风装置2包括有由定子结构14和转子结构12组合形成偏心的电机1，以及直接与转子结构12相接触的扇叶22，其中，转子结构12包括多个形成封闭图形的磁性件122，定子结构14设于多个磁性件122所形成的环形结构对应设置，以在对定子结构14中绕设于定子齿144上的定子绕组的电流方向进行控制时， 可产生不同极性的磁场，此时通过至少两个极性不同的定子绕组，可对转子结构12实现驱动，使得转子结构12带动负载实现转动。送风装置2还包括可拆卸连接的第一风罩24和第二风罩26，第二风罩26与第一风罩24连接后内部形成容纳空腔，转子结构12与定子结构14设于容纳空腔内，当然，定子结构14也可以对应设于容纳空腔外，或者定子结构14的多个定子铁芯142同时设于容纳空腔内或外。
其中，扇叶的结构如图7所示，扇叶整体呈环形，内壁上设有多个容纳磁性件的凹槽，转子结构的每个磁性件分别安装于凹槽内，以实现环形的转子结构。
进一步地，如图8所示，支撑结构16设于第一风罩24朝向第二风罩26的一侧，以在第一风罩24与第二风罩26连接时，支撑结构16置于容纳空腔内。
进一步地，如图6所示，第一风罩24和第二风罩26上均设有通风格栅28，通风格栅28沿径向分别向外延伸至第一风罩24的侧面和第二风罩26的侧面。
进一步地，如图8所示，支撑结构16为实心轴，支撑结构16上套设有轴套30，扇叶22套设在轴套30上，扇叶22通过轴套30与支撑结构16可转动地连接。
图9示出了支撑结构16的另一种形式，即支撑结构16为空心轴。扇叶22套设于支撑结构16上，支撑结构16的空心部分形成一个过风通道21，可使空气能够由扇叶22的一端通过过风通道21流向另一端。
实施例六
本申请的另一个实施例提供了一种送风装置2，如图10所示，包括有由定子结构14和转子结构12组合形成偏心的电机1，以及直接与转子结构12相接触的扇叶22，其中，转子结构12包括多个形成封闭图形的磁性件122，定子结构14设于多个磁性件122所形成的环形结构对应设置，以在对定子结构14中绕设于定子齿144上的定子绕组的电流方向进行控制时，可产生不同极性的磁场，此时通过至少两个极性不同的定子绕组，可对转子结构12实现驱动，使得转子结构12带动负载实现转动。送风装置2还包括有底座32， 底座32与扇叶22可拆卸的连接，定子结构14设于底座32上，定子结构14可随底座32一起与转子结构12分离。
在上述任一实施例的基础上，定子结构14朝向转子结构12的一侧的形状与转子结构12的侧面的形状相适配，即定子结构14形成外凸结构，一方面有利于定子结构14每个定子齿与转子结构12之间的距离保持相同，有利于转子结构12的受力均衡，另一方面可以通过消除定子结构14的异形结构减小定子结构14与转子结构12之间的间距，有利于增强转子结构12所受到的作用力。
可以理解，若定子结构14朝向转子结构12的一侧设有异形结构，例如凸起、凹槽、台阶等，需增大定子结构14与转子结构12之间的间距以免转子结构12的转动受到干涉，从而使得定子结构14对转子结构12的磁力作用受到削弱。
此外，电机1还包括壳体，支撑结构具体为设于壳体上的支撑轴，通过转子结构12可转动地设于支撑轴上，以使转子结构12绕支撑轴转动，防止转子结构12发生径向位移；而通过将定子结构14固定设于壳体上，以使得转子结构12与定子结构14之间的相对距离保持不变，以防止定子结构14受到转子结构12的反作用力而发生位移，以免影响转子结构12转动的稳定性。
其中，转子结构12可相对于定子结构14顺时针转动或逆时针转动，进一步地，可根据负载的转动需要实现正反两个方向的转动，可满足不同的负载需求，灵活性高。
以上结合附图详细说明了本申请的技术方案，在应用上述电机驱动负载运动时，可单独将负载连同转子结构一起拆下进行清洗或更换，便于操作，此外，定子铁芯设于转子结构的周向，一方面可减少电机整体在轴向方向的尺寸，另一方面可在周向方向对转子结构实现驱动，以带动转子所直接连接的负载进行转动。
