参阅图1至图3，以及图5与图7，本发明一实施例提供的鼓风机包括电机、定子支架400、安装座500与叶轮600，电机包括转子组件100、定子组件200、线路板300与电机壳710，定子组件200与线路板300电性连接。电机壳710与安装座500连接，定子组件200与线路板300设置于电机壳710与安装座500之间限定出的空腔内。安装座500与定子支架400沿第一方向排布，并且安装座500、线路板300与定子组件200三者也沿第一方向排布，定子支架400依次穿过线路板300与定子组件200。安装座500与定子支架400连接，线路板300安装于安装座500，定子组件200安装于定子支架400。叶轮600与转子组件100 的转子轴110连接，叶轮600能够在电机驱动下绕第一方向转动。其中，图2中从下向上的方向即为第一方向，上下方向也即电机的轴向，水平方向即为电机的径向。当然，附图中所示的方位仅为各部件的相对位置，并非鼓风机安装时的绝对位置。
上述鼓风机，安装座500与定子支架400连接，线路板300安装于安装座500，定子组件200安装于定子支架400，安装座500与定子支架400沿第一方向排布，安装座500、线路板300与定子组件200沿第一方向排布，也即线路板300位于安装座500与定子组件200之间。相较于常规方式中，线路板300外置于安装座500下方的安装方式，本方案可以充分利用鼓风机内部安装座500与定子组件200之间的空间，使各部件在电机的轴向上分布更加紧凑，整体轴向尺寸更小，鼓风机安装时，对安装空间的要求也更低，更易于安装在狭窄空间。同时，在拆装内部部件时也较为方便，例如，需要拆下线路板300时，只需先解除定子组件200与定子支架400的连接关系，然后将定子组件200朝上移动即可脱离定子支架400，再解除线路板300与安装座500的连接关系，然后将线路板300朝上移动即可脱离安装座500；需要组装时，只需将定子支架400安装于安装座500的顶部，再将定子支架400穿过线路板300，将线路板300连接于安装座500，然后将定子组件200套设于定子支架400，并将二者连接即可。
具体地，在一些实施例中，定子组件200与线路板300之间通过导线实现电性连接。或者，在一些实施例中，定子组件200与线路板300之间通过插针插槽等结构插接配合实现电性连接。优选地，定子支架400可以通过螺纹紧固件连接、卡接等可拆卸安装方式安装于安装座500的顶部，以便于后续的拆装维修。叶轮600包括扇叶620，叶轮600被电机驱动而进行转动时，其中的扇叶620也会转动，当扇叶620转动时，可以进行送风，加速气流流动。
参阅图2至图4，在一些实施例中，定子支架400包括基座410与至少一个伸出件420，伸出件420从基座410的外周部上朝外伸出，伸出件420与安装座500连接，伸出件420位于线路板300与安装座500之间，基座410依次穿过线路板300与定子组件200，安装座500上设置有朝第一方向伸出且连接于线路板300的线路板固定件520，线路板固定件520与伸出件420沿第一方向在线路板 300上的投影错开。
具体地，伸出件420连接于基座410靠近安装座500的一侧，即基座410上靠近底端的位置，伸出件420沿电机的径向朝外伸出。优选地，伸出件420与安装座500之间可拆卸连接，以便于后续的拆装维修。具体地，伸出件420与安装座500可以通过螺纹紧固件连接或卡接等方式安装。优选地，安装座500上设置有内凹的安装腔510，伸出件420与安装腔510的腔壁形状尺寸匹配，伸出件420容纳于安装腔510内。伸出件420的底部朝下凸出有固定柱，固定柱朝下穿过安装腔510的腔壁上对应位置处设置的通孔，以便于在安装时进行快速定位。安装座500的顶面上未设置安装腔510的区域处朝上伸出有线路板固定件520，线路板300上对应位置设置有固定孔330。线路板固定件520朝上伸出至伸出件420以上，线路板300支撑于线路板固定件520，线路板固定件520对准固定孔330，二者通过螺纹紧固件固定连接。优选地，安装座500的顶面上未设置安装腔510的区域处还朝上伸出有定位销530，线路板300上对应位置设置有定位孔340，定位销530插入定位孔340，以便于在安装时进行快速定位，并使线路板300安装后不易移位。优选地，线路板固定件520与定位销530均设置有多个，以使安装更牢固，定位效果更好。上述实施例中，由于线路板固定件520与伸出件420沿第一方向在线路板300上的投影错开，即线路板固定件520从安装座500的顶面上未设置安装腔510的区域处朝上伸出，可以保证线路板固定件520朝上伸出至伸出件420所在高度时，能够避开伸出件420，二者不会发生位置干涉，从而能充分利用伸出件420以外的空间，使部件的径向分布更加合理紧凑，有利于减小径向尺寸。当然，在另一些实施例中，若不考虑径向尺寸，也可以增大安装座500的径向尺寸，在安装座500上伸出至伸出件420外圈的部分设置朝上伸出的线路板固定件520，以避让伸出件420。或者，若对安装牢固程度要求不高，也可以减小伸出件420的径向尺寸，使伸出件420的外圈朝内缩，此时与增大安装座500径向尺寸的方式类似。
参阅图2至图4，在一些实施例中，基座410的外周部上伸出有多个沿电机的周向间隔分布的伸出件420，线路板固定件520经相邻的伸出件420之间伸出至线路板300。具体地，附图所示实施中，基座410上靠近底端的位置连接有三 个沿周向均匀间隔分布的伸出件420，相邻的伸出件420之间形成缺口，安装座500的顶面上设置的线路板固定件520朝上伸出时，穿过该缺口进行避让，不会发生位置干涉。通过设置多个伸出件420，可以使定子支架400与安装座500之间的安装更加牢固稳定；随着伸出件420的数量增多，线路板固定件520数量也会相应地增多，通过设置多个线路板固定件520，可以使线路板300与安装座500之间的安装更加牢固稳定。
参阅图2至4，在一些实施例中，基座410包括沿第一方向排布的支撑件411与压块412，支撑件411与压块412的连接处的外周部设有安装槽413，定子组件200包括伸入安装槽413的安装件250，支撑件411与压块412通过紧固件固定连接，以将安装件250夹持固定于安装槽413的槽壁。具体地，支撑件411上靠近顶部的位置呈下大上小的台阶状，以形成安装槽413的部分槽壁，压块412上靠近底部的位置近似呈上大下小的台阶状，以形成安装槽413的部分槽壁。定子组件200中定子铁芯210的内壁上朝内伸出有多个安装件250，安装件250的形状尺寸等与安装槽413相匹配。安装件250支撑于支撑件411的顶部，同时，压块412压在安装件250的顶部，压块412与支撑件411固定连接，从而将安装件250夹持固定，使定子组件200被悬空挂于基座410的外部。具体地，压块412与支撑件411可以通过螺纹紧固件连接，或者，也可以通过卡扣结构连接。优选地，安装件250为橡胶或硅胶材质，在被夹持固定时，不易因夹持力度过大而损坏。上述实施例中，基座410由支撑件411与压块412固定连接而形成，可以便于定子组件200的安装拆卸，在安装时，将定子组件200套在支撑件411的顶部，调整安装件250的位置，然后将压块412压在定子组件200的顶部，并与支撑件411通过螺钉锁紧固定即可；在拆卸时，只需拧下螺钉，取下压块412，即可将定子组件200拆除。在另一些实施例中，也可以在支撑件411的外周部设置朝外凸出的凸台，将定子组件200套设于基座410的外部，且安装件250支撑于该凸台上，同时，将压块412压紧在安装件250的顶部，并将压块412与支撑件411固定连接。
参阅图2、图5与图7，在一些实施例中，转子组件100包括转子轴110、磁瓦130与转子壳120，转子轴110穿过定子支架400且二者通过轴承720连接， 转子壳120套设于转子轴110并延伸至定子组件200的外周部的外侧，磁瓦130安装于转子壳120的内壁，磁瓦130与定子组件200沿电机的径向排布，且磁瓦130与定子组件200之间具有间隙。具体地，转子壳120沿径向朝外延伸，并在外端处沿轴向朝下延伸，呈底部敞口顶部封闭的形状，转子壳120的内侧壁设置有多个磁瓦130。定子组件200中的线圈缠绕部220用于缠绕线圈，磁瓦130位于线圈沿径向的外侧，二者之间具有间隙。磁瓦130与通电的线圈相互作用，从而使磁瓦130转动，并带动转子壳120与转子轴110转动，通过转子轴110输出动力。本实施例中，将定子支架400设置于定子组件200内部，并通过定子支架400同时实现定子组件200与转子组件100的安装，可以充分利用定子组件200内部的空间，减小电机的轴向与径向尺寸；同时，若因外部因素导致鼓风机晃动，由于定子组件200与转子组件100均安装于定子支架400，可以使定子组件200与转子组件100之间的相对位置不变，二者不易发生相对位移，更易于保持较高的同轴度，电机输出性能更加稳定。
具体地，在一些实施例中，定子支架400中，支撑件411与压块412内部中空，转子轴110依次穿过支撑件411与压块412，转子轴110与支撑件411之间，以及转子轴110与压块412之间均通过轴承720连接。本实施例中，通过在转子轴110与支撑件411之间，以及转子轴110与压块412之间均设置轴承，可以提高安装的稳定性，更易于使定子组件200与转子组件100保持较高的同轴度，电机输出性能更加稳定。
参阅图1与图2，在一些实施例中，叶轮600包括连接罩610与多个沿电机的周向间隔排布的扇叶620，沿电机的径向，连接罩610的内端安装于转子组件100的转子轴110，连接罩610的外端连接有朝第一方向伸出的扇叶620，沿第一方向，连接罩610的外端与安装座500的间距小于连接罩610的内端与安装座500的间距。具体地，连接罩610近似呈锥形，沿第一方向，连接罩610与转子轴110的径向间距逐渐减小。连接罩610的内端连接于转子轴110的外周部，且靠近转子轴110的顶端。连接罩610的外端位置更加靠下，也就是使扇叶620的始端位置更加靠下，从而充分利用定子组件200外部的空间，使结构更加紧凑，扇叶620的末端位置不会过高，鼓风机整体轴向尺寸不会过大。
在一些实施例中，电机壳710套设于转子轴110上，电机壳710位于连接罩610与转子壳120之间。电机壳710通过螺钉固定连接于安装座500上，从而将位于二者限定出的空腔内的各部件包围，起到隔绝外界环境与保护内部部件的作用。优选地，电机壳710与安装座500之间设置有密封圈，以增强连接处的密封性。
优选地，在一些实施例中，转子壳120、连接罩610与电机壳710三者至少在部分区域的延伸方向相同。具体地，如图2所示，转子壳120、连接罩610与电机壳710三者均不仅沿电机的径向朝外延伸，且沿电机的轴向延伸。例如，转子壳120中用于安装磁瓦130的外端板呈环形板，其沿上下方向(即电机轴向)延伸，连接罩610与电机壳710二者在该区域也近似呈环形状，因此可以近似认为，在转子壳120的外端板的高度范围内，转子壳120、连接罩610与电机壳710三者延伸方向相同。当然，除了上述列举的区域，还存在其他类似的区域，此处不一一列举。如此设置后，可以使转子壳120、连接罩610与电机壳710三者分布更加紧凑，使径向尺寸与轴向尺寸都更小。优选地，在各部件不造成位置干涉的前提下，可以尽量使上述三个部件的延伸方向完全相同，即任意两者之间等间距，以最大限度的增加紧凑度，使尺寸更小。
参阅图3与图4，在一些实施例中，伸出件420与安装座500之间设置有第一弹性缓冲件540，且伸出件420与安装座500二者均与第一弹性缓冲件540的形状匹配。具体地，第一弹性缓冲件540可以选用橡胶或硅胶材质制成。当伸出件420与安装座500通过螺钉紧固安装后，第一弹性缓冲件540可以起到减震缓冲的作用，以免因外部因素导致安装座500晃动时，传递至定子组件200与转子组件100的晃动幅度过大而造成零部件移位甚至损坏。
具体地，在一些实施例中，安装座500上设有与第一弹性缓冲件540形状匹配的安装腔510，第一弹性缓冲件540设置于安装腔510内，第一弹性缓冲件540包括第一缓冲部541，以及沿电机的径向延伸的第二缓冲部542，沿电机的径向，第一缓冲部541连接于第二缓冲部542的外端，且第一缓冲部541从第二缓冲部542与第一缓冲部541的连接处沿电机的周向朝两侧延伸。具体地，第一弹性缓冲件540与安装腔510的腔壁形状尺寸等匹配，第一弹性缓冲件540 位于伸出件420与安装腔510的腔壁之间。第二缓冲部542连接于第一缓冲部541上沿电机周向的中心位置，即第一缓冲部541从二者连接处朝沿周向两侧延伸的长度相等。对应的，安装腔510也设置为与第一缓冲部541与第二缓冲部542形状尺寸匹配，伸出件420也设置为与第一缓冲部541与第二缓冲部542形状尺寸匹配。上述实施例中，通过设置延伸方向不同的第一缓冲部541与第二缓冲部542，并将伸出件420与安装腔510也设置为对应形状，可以利用第一缓冲部541与第二缓冲部542二者与安装腔510对应位置的配合实现周向与径向两个方向的限位，第一弹性缓冲件540能更稳定的被安装于安装腔510内而不易移位。
进一步地，在一些实施例中，第一弹性缓冲件540上设有与伸出件420形状匹配的限位槽543，伸出件420设置于限位槽543内，伸出件420上设有凸出部421，第一弹性缓冲件540上对应位置处设置有第一通孔544，安装座500上对应位置处设置有第二通孔511，凸出部421依次穿过第一通孔544与第二通孔511。具体地，两个凸出部421分别设置于第一缓冲部541上沿周向的两端。伸出件420设置于限位槽543内，可以较好的实现伸出件420与第一弹性缓冲件540之间的限位，使二者不易发生相对位移，从而保证较好的缓冲减震效果。凸出部421依次穿过第一通孔544与第二通孔511，可以进一步增强限位，同时，还能在组装过程中快速定位。
参阅图6至图9，在一些实施例中，定子组件200包括弹性连接端子240与线圈，线圈通过弹性连接端子240电性连接于线路板300，弹性连接端子240能够沿两两垂直的三个方向中的任意一个弹性变形，线圈与线路板300在空间内发生相对位移时，弹性连接端子240能够弹性变形，以使线圈与线路板300相对位移后保持电性连接。具体地，定子铁芯210的底部朝下伸出有电性连接于线圈的定子铁芯连接端子230，弹性连接端子240的首端248电性连接于定子铁芯连接端子230，尾端249电性连接于线路板300，弹性连接端子240选用弹性较好的导电材质制成。若鼓风机受外界环境影响发生晃动，线圈与线路板300可能出现相对位移过大而接触不良的情况。通过设置弹性连接端子240，可以为线圈与线路板300预留三个方向的相对位移空间，使得二者即使发生相对位移， 也能通过弹性连接端子240的弹性变形保持电性连接，不易因接触不良而导致电机停止工作；并且不易因线圈与线路板300之间的刚性拉扯而造成线圈或线路板300变形损坏。具体地，弹性连接端子240可以为线圈与线路板300预留上下、左右、前后三个方向的相对位移空间，使线圈与线路板300发生其中任意一个方向的相对位移时，均能通过弹性连接端子240的弹性变形保持电性连接，不易因接触不良而导致电机停止工作；并且不易因线圈与线路板300之间的刚性拉扯而造成线圈或线路板300变形损坏。
参阅图6至图9，在一些实施例中，弹性连接端子240包括至少三个均呈板状的弹性部，其中，以相邻的弹性部的板面交线为连接轴，相邻的两个弹性部能够绕连接轴相对转动，部分相邻的弹性部之间的连接轴为第一类连接轴，部分相邻的弹性部之间的连接轴为第二类连接轴，第一类连接轴的轴向与第二类连接轴的轴向垂直。具体地，以第一类连接轴的轴向为第二方向，以第二类连接轴的轴向为第三方向，第二方向垂直于第三方向。在附图所示实施例中，弹性连接端子240包括依次相连的第一弹性部241、第二弹性部242与第三弹性部243。在附图9所示视角下，第二方向为上下方向，第三方向为前后方向，以第一弹性部241的长度方向为左右方向。其中，第一弹性部241、第二弹性部242通过第一类连接轴相连，二者可以绕第二方向相对转动，从而能够适应第一弹性部241在前后方向上的位移，并适应第二弹性部242在左右方向上的位移。当然，实际上第一弹性部241、第二弹性部242绕第二方向相对转动时，也能适应第一弹性部241在左右方向上的微小位移，并适应第二弹性部242在前后方向上的微小位移，由于位移量较小，下面描述中仍以主要位移为主进行解释说明。类似地，第二弹性部242、第三弹性部243通过第二类连接轴相连，二者可以绕第三方向相对转动，从而能够适应第二弹性部242在左右方向上的位移，并适应第三弹性部243在上下方向上的位移。因此，本实施例通过第一弹性部241、第二弹性部242、第三弹性部243之间的相对转动，适应前后、左右、上下三个方向的位移，为线圈与线路板300预留三个方向的相对位移空间，使得二者即使发生相对位移，也能通过弹性连接端子240的弹性变形保持电性连接。
优选地，在一些实施例中，多组相邻的所述弹性部的所述连接轴为所述第 一类连接轴，和/或，多组相邻的所述弹性部的所述连接轴为所述第二类连接轴。如此设置后，可以增大整个弹性连接端子240绕第二方向以及/或者第三方向转动的幅度，从而能够适应适应更大的位移量，为线圈与线路板300预留更大程度的相对位移空间。具体地，弹性连接端子240包括依次相连的第一弹性部241、第二弹性部242、第三弹性部243、第四弹性部244、第五弹性部245、第六弹性部246、第七弹性部2471与第八弹性部2472。与上一实施例类似，第三弹性部243、第四弹性部244也通过第二类连接轴相连，二者可以绕第三方向相对转动，从而能够适应第三弹性部243在上下方向上的位移，并适应第四弹性部244在左右方向上的位移。第四弹性部244、第五弹性部245也通过第二类连接轴相连，二者可以绕第三方向相对转动，从而能够适应第五弹性部245在上下方向上的位移，并适应第四弹性部244在左右方向上的位移。第五弹性部245、第六弹性部246也通过第二类连接轴相连，二者可以绕第三方向相对转动，从而能够适应第五弹性部245在上下方向上的位移，并适应第六弹性部246在左右方向上的位移。第六弹性部246、第七弹性部2471通过第一类连接轴相连，二者可以绕第二方向相对转动，从而能够适应第六弹性部246在左右方向上的位移，并适应第七弹性部2471在前后方向上的位移。第七弹性部2471与第八弹性部2472也通过第一类连接轴相连，二者可以绕第二方向相对转动。由于第七弹性部2471与第八弹性部2472的板面均与第一弹性部241的板面之间存在夹角，因此，相较于上一实施例中提到的适应第一弹性部241在左右方向上的微小位移，并适应第二弹性部242在前后方向上的微小位移，本实施例能够适应第六弹性部246在左右方向与前后方向上的较大位移，并适应第七弹性部2471在左右方向与前后方向上的较大位移。当然，除了附图所示实施例，还可以继续增加弹性部的数量，以适应适应更大的位移量。
优选的，任意相邻的两个弹性部之间圆滑过渡，以使得相邻的弹性部之间的相对转动不易造成两个弹性部连接处的断裂。例如，任意相邻的两个弹性部之间可以倒圆角。
或者，在另一些实施例中，弹性连接端子包括均呈圆柱状的第一弹性件与第二弹性件，第一弹性件沿自身轴向的一端与第二弹性件沿自身轴向的一端连 接，第一弹性件的轴向与第二弹性件的轴向存在夹角，第一弹性件与第二弹性件能够相对于二者连接处转动。以图9中第一弹性部241、第二弹性部242为例进行说明，例如，第一弹性部241、第二弹性部242均为圆柱状，当二者相对转动时，第一弹性部241可以上下转动，还可以前后转动，第二弹性部242可以上下转动，还可以左右转动，因此，仅通过两个弹性件即可适应上下、左右、前后三个方向的位移，为线圈与线路板300预留三个方向的相对位移空间，使得二者即使发生相对位移，也能通过弹性连接端子240的弹性变形保持电性连接。
参阅图4、图6至图9，在一些实施例中，线路板300上设有供定子支架400穿过的避让孔320，弹性连接端子240的首端248电性连接于线圈，弹性连接端子240的尾端249电性连接于线路板300，沿第一方向，首端248与尾端249分别位于线路板300的两侧，弹性连接端子240中位于首端248与尾端249之间的中间段位于避让孔320内。具体地，弹性连接端子240的首端248位于线路板300的上方，弹性连接端子240的尾端249位于线路板300的下方。基座410穿过避让孔320，且基座410与避让孔320的孔壁之间具有间隙，弹性连接端子240中位于首端248与尾端249之间的中间段即可设置于该间隙处。具体地，弹性连接端子240的首端248从定子铁芯连接端子230处朝下并朝内延伸，到达上述间隙处，并继续朝下延伸至线路板300的下方，再朝外与朝上延伸，插接于线路板300上设置的插槽310内。由于弹性连接端子240包括多个弹性连接部241与弹性过渡部242，整体尺寸略大，将其中间段容纳于避让孔320，可以充分利用避让孔320内的空间，减小定子组件200与线路板300的间距，从而使鼓风机整体轴向尺寸更小。
参阅图10至图12，在一些实施例中，车内通风系统包括上述任意一个实施例中的鼓风机810，还包括鼓风机连接件820，鼓风机810安装于鼓风机连接件820。需要说明的是，图10至图12中的鼓风机810仅用于示意其安装方式，具体结构如图1所示。
参阅图10至图12，在一些实施例中，鼓风机连接件820为空调箱，鼓风机810可拆卸连接于空调箱。具体地，鼓风机810与鼓风机连接件820卡扣连接， 例如，鼓风机810上设置有卡钩811，鼓风机连接件820上对应位置设置有卡块821，卡块821卡入卡钩811以实现固定连接。在其他实施例中，卡块821与卡钩811位置可以互换，也可以成对增加卡块821与卡钩811的数量，以使安装更加牢固。在其他实施例中，鼓风机810与鼓风机连接件820也可以通过螺钉等螺纹紧固件连接。优选地，鼓风机810上还设有限位孔812，鼓风机连接件820上对应位置设置有限位柱822，限位柱822插接于限位孔812，以在安装时进行快速定位。在其他实施例中，限位柱822与限位孔812位置可以互换，也可以成对增加限位柱822与限位孔812的数量。
参阅图10至图12，在一些实施例中，鼓风机810与鼓风机连接件820之间设置有第二弹性缓冲件830。具体地，在一些实施例中，鼓风机810上设置有第一凹槽813，鼓风机连接件820上对应位置设置有第二凹槽823，当鼓风机810安装于鼓风机连接件820时，第二弹性缓冲件830卡于第一凹槽813的槽壁与第二凹槽823的槽壁之间，鼓风机810的端面与鼓风机连接件820的端面具有间隙。具体地，第一弹性缓冲件540可以选用橡胶或硅胶材质制成。在鼓风机810安装于鼓风机连接件820时，第二弹性缓冲件830被第一凹槽813的槽壁与第二凹槽823的槽壁挤压变形。鼓风机810安装于鼓风机连接件820时，鼓风机810的端面与鼓风机连接件820的端面依然具有间隙，因此，当鼓风机810工作时，其产生的振动可以较大程度通过第二弹性缓冲件830进行缓冲，减小传递至鼓风机连接件820的震动幅度与震动噪音。
在一些实施例中，第一凹槽813与第二凹槽823的长度方向均沿鼓风机810的周向，第一凹槽813与第二凹槽823的宽度方向均沿鼓风机810的径向，第一凹槽813与第二凹槽823的高度方向均沿鼓风机810的轴向；沿鼓风机810的径向，第一凹槽813与第二凹槽823的槽壁均呈弧形延伸。具体地，以第一凹槽813为例，沿鼓风机810的径向，内外两端凹槽深度较大，中间深度较小，第二凹槽823与第一凹槽813形状类似。如此设置可以更稳定的卡住第二弹性缓冲件830，使其不易掉落，从而更好的实现减震。
优选地，第一凹槽813与第二凹槽823的槽壁均通过横纵交错的筋条形成，如此设置可以使其鼓风机810与鼓风机连接件820上沿周向各个区域的厚度较 较为均匀，避免为了成型出第一凹槽813与第二凹槽823而导致鼓风机810与鼓风机连接件820上出现局部尺寸过于肥大，在注塑成型结束后更易于脱模。
在一些实施例中，第二弹性缓冲件830的最大压缩量为b，第二弹性缓冲件830卡于第一凹槽813的槽壁与第二凹槽823的槽壁之间，且第二弹性缓冲件830未压缩时，鼓风机810的端面与鼓风机连接件820的端面的间隙为a，b＜a，且0.7≤b/a≤0.9。由于第二弹性缓冲件830未压缩时，鼓风机810的端面与鼓风机连接件820的端面的间隙为a大于第二弹性缓冲件830的最大压缩量为b，则即使第二弹性缓冲件830达到最大压缩量，鼓风机810的端面与鼓风机连接件820的端面依然会存在间隙，从而可以保证在鼓风机810与鼓风机连接件820固定安装之后，可以通过第二弹性缓冲件830进行减震，并避免在鼓风机810震动过程中其端面碰撞鼓风机连接件820的端面而造成损伤。当b/a满足上述范围时，可以保证鼓风机810与鼓风机连接件820固定安装之后，二者之间的间隙不会过大，灰尘杂物等不易进入；还可以保证二者之间间隙不会过小，鼓风机810震动过程中，鼓风机810的端面与鼓风机连接件820的端面不会发生碰撞。以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
