具体地，该风机100包括有风机风筒1，风机风筒1呈圆筒形。风机风筒1的一端为风筒进风端11，其另一端为风筒出风端12。
一个扇叶3处于风筒进风端11中，另一个扇叶3处于风筒出风端12中。
风机马达2安装在风机风筒1中，其处于风筒进风端11和风筒出风端12之间。优选地，风机马达2处于风机风筒1的中部。

在其中一个实施例中，如图2和图12所示，两个扇叶3都为轴流扇叶31。
轴流扇叶31包括中心盘311和多片倾斜布置的叶片312。中心盘311与转轴4连接，在转轴4被风机马达2带动转动时，叶片推动空气以与风机风筒1的轴向相同的方向流动，利于气流在风机风筒1中快速移动。
在其中一个实施例中，如图8－9和图13所示，处于风筒进风端11中的扇叶3为离心扇叶32，处于风筒出风端12中的扇叶3为轴流扇叶31。
本实施例中，风筒进风端11的扇叶3为离心扇叶32，风筒出风端12的扇叶3为轴流扇叶31。离心扇叶32用于将气流引导向离心扇叶32的侧部，也即是使得气流吹向风机风筒1的内壁侧，避开中间的风机马达2，再经轴流扇叶31作用离开风筒出风端12。
本实施例中，通过在风筒进风端11中配置离心扇叶32，可减少气流吹向中心的风机马达2，利于气体顺利流动，也有利于降低风噪。
在其中一个实施例中，如图10所示，离心扇叶32包括扇叶圆环321、圆形的扇叶底板322和多条肋板323。
扇叶底板322与转轴4连接，扇叶圆环321的半径大于扇叶底板322的半径，扇叶圆环321与扇叶底板322同轴布置。
多条肋板323间隔地连接在扇叶圆环321与扇叶底板322之间，任意相邻的两条肋板323之间形成有离心出风口324。

在其中一个实施例中，如图11－13所示，风筒出风端12包括有扩张部121，其中一个 扇叶3处于扩张部121中。在沿着从风筒进风端11至风筒出风端12的方向上，扩张部121的半径逐渐变大。
本实施例中，通过改变风筒出风端12的形状，在沿着气流的流向上，风筒出风端12的扩张部121的半径逐渐变大，利于气体快速向风筒出风端12流动排出，进一步提高了风机100的吸风量和吸风能力。
在其中一个实施例中，如图2所示，风机马达2包括有马达定子21和处于马达定子21中的马达转子22，转轴4穿过马达转子22，转轴4与马达转子22同步转动。
本实施例中，两个扇叶3通过一根转轴4连接，转轴4穿过风机马达2的马达转子22，转轴4与马达转子22可通过键连接，马达转子22在相对于马达定子21转动时，带动转轴4一体转动，结构体积小，并方便安装。
在其中一个实施例中，如图2－3、图8和图12－13所示，风机风筒1中具有两个连接支架14，两个连接支架14处于风机马达2的相对两侧，每个连接支架14上都具有支架环141。
转轴4上具有两个用于与支架环141配合的装配环5，两个装配环5处于风机马达2的相对两侧。
装配环5套接在转轴4上，装配环5可枢转地安装在支架环141中。或者，装配环5固定安装在支架环141中，转轴4间隙穿过装配环5。
本实施例中，在风机风筒1中安装有两个连接支架14，连接支架14的主体上具有支架通风孔，连接支架14的中部具有支架环141。风机马达2处于两个连接支架14之间。
与每个扇叶3连接的转轴4上都装配有装配环5，两个装配环5分别与两个支架环141装配，以支撑起转轴4。
转轴4、装配环5及支架环141具有如下两种连接方式：
连接方式一：装配环5套接在转轴4上，装配环5与转轴4一体转动。装配环5间隙配合在支架环141中，装配环5可在支架环141中转动。根据需要，可在支架环141的两侧设置有挡边，以挡住装配环5。
连接方式二：装配环5固定安装在支架环141中，转轴4穿过装配环5的中心孔51，转轴4可在中心孔51中转动。根据需要，可在转轴4上开设限位槽，以避免转轴4与装配环5发生轴向位移。
在其中一个实施例中，如图1－2、图4、图7－8和图11－13所示，风筒进风端11和风筒出风端12上分别配置有风筒盖板13，风筒盖板13具有多个通风口131。
风筒盖板13可通过螺钉、卡扣等安装在风机风筒1的端部。风筒盖板13既起到保护内部结构的作用，又具有通风功能。
如图14－16所示，本申请一实施例的提供一种扫地机器人200，包括行走底盘201、安装在行走底盘201上的集尘盒203、安装在行走底盘201上的风道205和前述任一实施例所述的风机100。

风道205具有风道进风端2051和风道出风端2052，风道出风端2052处于行走底盘201的侧部。在安装好集尘盒203后，滤芯204处于风道进风端2051中，起到阻挡杂物进入风 道205的作用。
由于，风机100中具有两个扇叶3，提高了吸风量，增强了吸力，较大颗粒的杂物也可被吸入到集尘盒203中，改善了清扫效果。
在其中一个实施例中，如图16所示，风道205包括风道下壳2053和与风道下壳2053可拆卸连接的风道上壳2054，风机100的风机风筒1固定安装在风道下壳2053上。

综上所述，本申请提供的风机及扫地机器人，在风机风筒1中配置两个扇叶3，两个扇叶3同步转动，提高了吸风量，增强了吸力，较大颗粒的杂物也可被吸入到集尘盒203中，改善了清扫效果。
本申请实施例中的扫地机，如图17到图21所示，包括底板6、滚刷罩7、滚刷组件8和升降器。其中，底板6主要起到基础支撑的作用。滚刷罩7设置在底板6的下侧，主要起到安装滚刷组件8以及罩设滚刷组件8的作用。滚刷组件8与滚刷罩7旋转式连接，并且部分外露于滚刷罩7，用于接触地面，以对地面进行清洁。升降器设置在滚刷罩7与底板6之间。升降器用于带动滚刷罩7进行升降运动，进而用于在需要例如，遇到障碍物时，带动滚刷组件进行升降。
由此，在本申请中，通过设置升降器进而实现滚刷组件8的升降运动，从而在遇到障碍物或者不需要滚刷组件进行清洁的地方进行上升运动，以跨过障碍物等，提高了扫地机的服务范围和客户体验。
特别说明的是：本实施例中的扫地机与上一实施例中的扫地机器人200可为同一种机器，仅是称呼不同。本实施例中的扫地机中的底板6可为上一实施例中的扫地机器人200的行走底盘201的底板。
在一个实施例中，如图19和图20所示，升降器包括第一升降件91、第二升降件92和驱动组件。第一升降件91为两个，并分别设置在滚刷罩7的轴向两端。第一升降件91为大体的方形体结构。连接后，第一升降件91向上穿过底板6，并与底板6滑动式连接。在第一升降件91上设置升降孔93。该升降孔93的孔延伸方向与滚刷罩7的轴向一直。同时，第二升降件92设置在底板6上。第二升降件92也为两个。各第二升降件92有用于延伸到升降孔93内的升降板94。升降板94与升降孔93斜面配合。驱动组件用于驱动第二升降件92沿着滚刷罩7的轴向运动，进而通过升降板94带动第一升降件91进行爬坡或者下坡，进而带动滚刷罩7进行升降运动。
更加具体地，升降孔93在沿着滚刷罩7的轴向上包括两段，其中，靠近内侧的一段为在沿着滚刷罩7的轴向的截面上为梯形，并且，在轴向的内到外方向上，升降孔93的通流面积逐渐变小，而靠近外侧的一段为在沿着滚刷罩7的轴向的截面上为方形，也就是说，在轴向上通流面积不变化。同时，在沿着滚刷罩7的轴向上，升降板94也包括两段。其中，靠近内侧的一段为梯形体，并且梯形体的斜面与升降孔93的相关处的斜面相对设置，靠近外侧的一段截面为方形。上述配合结构使得在第二升降件92轴向向外移动过程中，靠近内侧的一段抵接到升降孔93的靠近内侧的斜面壁上，随着第二升降件92的轴向移动，促动第一升降件91沿着斜面进行爬坡，进而带动滚刷罩7进行提升。由此，本申请依靠斜面配合能实现滚刷罩7升降运动。当然，通过沿着滚刷罩7的轴向外侧非斜面配合还可以实现限位、预连接等。
驱动组件具有动力源95和齿条机构96。其中，动力源95为电机。而齿条机构96设置在动力源95与第二升降件92之间，用于将电机的旋转运动转换为第二升降件92的直线运动。这种设置结构简单，易于实现。
在滚刷罩7与底板6之间设置弹性件97。优选地，该弹性件97为弹簧。如图17所示，在底板6上设置有多个弹簧罩61，以用于放置和限定弹簧。在图18所示的状态下，弹簧处于自然状态下，并从弹簧罩61延伸出并抵接到滚刷罩7的外壁上。待滚刷罩7被提升逐 渐靠近底板6，弹簧受到压缩，如图17所示。待升降孔93相对于升降板94为下坡后，在弹簧的自身弹力下，以及滚刷罩7和滚刷组件的重力作用下，该滚刷罩7下移。也就是说，该弹簧起到了促动滚刷罩7下移复位的作用。
在底板6上设置有微动开关98。微动开关98设置在第二升降件92的行程上，以用于第二升降件92的控制停止。例如，在第二升降件92沿着滚刷罩7的轴向向外侧移动过程中，滚刷罩7提升到位，此时第二升降件92遇到处于外侧的微动开关98，则微动开关98发送信号，控制动力源95电机停止并阻止第二升降件92进一步移动。同理地，在第二升降件92沿着滚刷罩7的轴向向内侧移动过程中，滚刷罩7下降到位，此时第二升降件92遇到处于内侧的微动开关98，则微动开关98发送信号，控制电机停止并阻止第二升降件92进一步移动。通过设置微动开关98可以进行行程控制，保证运动精准性和自动性。
在使用该扫地机的过程中，当扫地机检测到有障碍物时，先控制动力源95打开，动力源带动齿条机构96运动，进而促动第二升降件92向滚刷罩7的轴向的外侧进行运动。在第二升降件92运动过程中，通过斜面配合，促动第一升降件91进行爬坡运动，进而带动滚刷罩7和滚刷组件8进行上升。直至第二升降件92遇到微动开关98，动力源95关闭，第二升降件92运动停止，并且滚刷罩7和滚刷组件8上升到位。相反地，在需要放下滚刷罩7和滚刷组件8时，先开启动力源95，带动齿条机构96运动，进而促动第二升降件92向滚刷罩7的轴向的内侧进行运动。在第二升降件92运动过程中，通过斜面配合，促动第一升降件91进行下坡运动。在弹簧的自身弹力下，以及滚刷罩7和滚刷组件的重力作用下，该滚刷罩7和滚刷组件8下移触地。第二升降件92运动直至遇到微动开关98，控制动力源95关闭，第二升降件92停止运动。
滚刷组件8包括支撑件81和包覆在支撑件81的外壁上的滚刷层82。滚刷层82至少部分外露于滚刷罩7。在滚刷罩7的外侧设置有驱动电机83，该驱动电机83用于驱动支撑件81进行旋转，进而带动滚刷层82进行旋转，而进行拖地清洁工作。
滚刷罩7的内侧上固定设置有给水件84。给水件84沿着滚刷层82的轴向长度方向布设。给水件84为板状，其上设置有多个连通孔(图中未示出)，以用于接受来自供水管85的清洁水并将清洁水送到滚刷层82。也就是说，供水管85连通到清水箱10－1，在需要时，供给管72由清水箱10－1泵送式输送水，到给水件84上，水通过连通孔后落到滚刷层82上，以打湿滚刷层82。
滚刷罩7上固定设置有刮水件86。刮水件86沿着滚刷层82的轴向长度方向布设并压紧式抵接到滚刷层82上。刮水件86构造为板状，用于进行挤水操作，将拖过地的脏水挤压出去。
在滚刷罩7上固定设置有脏水收集槽87。脏水收集槽87的开口朝向滚刷层82。脏水收集槽87位于刮水件86的下侧方向上，在滚刷层82转动过程中，刮水件86挤压滚刷层82中的脏水，脏水落入到脏水收集槽87中，以对脏水进行收集。该脏水收集槽87连通到脏水箱10－2，用于将脏水存储到脏水箱10－2中。
由此，本申请的扫地机在清洁工作中，通过供给管72供水到给水件84上，水通过连通孔后落到滚刷层82上，以在滚刷层82进行清洁过程中，不断被喷净水。然后，通过刮水件86将滚刷层82所产生的污水挤压出来，能时刻保持滚刷层82处于洁净状态，避免滚刷层82持续对地面清洁时，在处于脏污状态还继续擦地，对地面造成二次污染，并且不需要频繁取下滚刷层82进行清洗更换，使用效率更高。也就是说，本申请的扫地机具有自清洁效果。上述表达了滚刷组件8进行清洁拖地的工作状态。但是需要说明的是，在滚刷组件8进行上升后的状态下，也可以根据情况停止滚刷层82转动，进而停止供水管85供水。当然，还可以使得滚刷层82继续转动，并使得供水管85依照进行供水清洁滚刷层82，而脏水收集槽87持续进行收集污水工作，这样可以对该滚刷层82进行进一步地深度清洁。
可以理解的是，为了保证净水供给及污水回收的快速稳定性，扫地机还包括设于底板6上的净水泵(图中未示出)及污水泵(图中未示出)。净水泵分别与清水箱10－1、供水管85连通，通过净水泵将清水箱10－1内的净水抽吸到供水管85内并喷出。污水泵分别与脏 水收集槽87、脏水箱10－2连通，通过污水泵将脏水收集槽87内的污水快速抽吸至脏水箱10－2内。
在一个实施例中，给水件84与刮水件86的自由端相互靠近并连接，以形成径向截面为V型结构。给水件84构造为从相对面(与刮水件86相对的并靠近刮水件86的那面)到相背面(与刮水件86相背的并远离刮水件86的那面)方向与滚刷组件8的转动方向(图中箭头标识的方形)一致，而刮水件86构造为从相对面到相背面方向与滚刷组件8的转动方向逆向。一方面，V型结构可以增加尤其刮水件86的强度，保证挤压水的效果。另一方面，刮水件86还起到了阻挡清水的作用，保证清水更加均匀的落到滚刷层82上。再一方面，上升设置可以保证清洁水喷洒和脏水挤压，最大范围的利用水资源。
优选地，给水件84构造为倾斜的斜板，连通孔呈矩阵式设置。也就是说，给水件84为倾斜的筛网板。这种设置可以适当增加给水面积，保证给水均匀性和充足性。另外，刮水件86构造为向给水件方向凸出的弧状板。这种设置可以保证刮水件86更好的配合并挤压滚刷层82，保证脏水的有效挤出滚刷层82。
在一个具体的实施例中，供水管85供水可以为多个，并沿着滚刷层82的轴向间隔式均匀布设，用于保证滚刷层82各个位置喷涂均匀。还可以根据需要在供水管85的出水口处设置喷嘴(图中未示出)，用于提高喷洒的均匀性。
根据本申请，在刮水件86的相背面的一侧设置上设置有梳齿(图中未示出)。梳齿的自由端抵接到滚刷层82上。通过梳齿能够将滚刷层82擦地粘附的垃圾刮掉，例如，毛发等，进一步保证滚刷层82的洁净。
根据需要，可以将上述各技术方案进行结合，以达到最佳技术效果。
以上的仅是本申请的原理和较佳的实施例。应当指出，对于本领域的普通技术人员来说，将分别公开在不同的实施例中的技术方案适当组合而得到的实施方式也包括在本申请的技术范围内，在本申请原理的基础上，还可以做出若干其它变型，也应视为本申请的保护范围。
