背景技术
随着科技的迅速发展,人们的生活水平越来越高,同时对生活质量要求也越来越高,对环境卫生也越来越注重。因此,市场上出现了多种多样的清洁装置,给人们的生活带来了诸多便捷。
以手持式清洁装置为例,为了达到清洁的工作效果,手持式清洁装置需要通过负压发生器的吸力产生气流来吸取要清洁的目标物,而在将目标物吸取至清洁装置内后,气流需排出清洁装置外,因此,手持式清洁装置往往还设置有与负压发生器连通的出风结构以将气流排至清洁装置外。
现有技术中,出风结构出于轻便小巧的目的,通常结构紧凑,内部空间尺寸较小,排气风道短,在清洁装置工作时,负压发生器产生的气流经由出风结构排出,气流与出风结构的边框摩擦会产生噪音,从而导致清洁装置的排气噪音大,尤其是噪音中的尖音部分,会产生刺耳和不适感。

本实施例提供一种出风结构100,适用于清洁装置,以将清洁装置的负压发生器与手柄管连接。其中,负压发生器与清洁装置的尘盒连通,以在尘盒内产生负压,待清洁面上的污物在负压作用下进入至尘盒内,而气流则流向至出风结构100,并自该出风结构100流出至清洁装置外。其中,待清洁面可以为地面、墙面,或者待清洁物体的表面,在此不做具体限定,根据实际情况而定。
请参照图1至图4所示,出风结构100包括本体1,本体1上具有进风口11、出风口12、以及连通进风口11和出风口12的风道,上述的自尘盒的出尘口流出的气流流经负压发生器后,自进风口11进入出风结构100内的风道,再经由与风道连通的出风口12排出清洁装置,从而实现清洁装置内气流的流动。
具体的,本体1包括第一端部14、与第一端部14相对设置的第二端部16、以及连接第一端部14与第二端部16的连接部13,第一端部14、第二端部16及连接部13之间形成上述风道,第一端部14形成进风口11,该进风口11设置在风道的长度方向的一端,本体1与进风口11相对的一端呈封闭端,出风口12设置在风道的侧壁上,风道连通进风口11和出风口12,以使得从第一端部14的进风口11进入风道的气流能从侧壁上的出风口12流出。
呈上述,出风结构100主要起承接作用。同时,由于其设置在负压发生器的一侧,不可对负压发生器的出气口造成阻碍,保证负压发生器的排气顺畅。因此,在现有技术 中,出风结构100的侧壁上设置有若干个矩形窗口,气流自负压发生器的排气口流出进入至出风结构100内,再通过矩形窗口流出至出风结构100外。但是,为了保证清洁装置的清洁效率,故负压发生器所形成的负压较强,致使形成的气流流速较快。流速较快的气流自身会产生尖音,且流速较快的气流自矩形窗口流出时,会与矩形窗口的边棱摩擦产生噪音,从而导致清洁装置的排气噪音大。尤其是噪音中的尖音部分,会产生刺耳和不适感。
为了解决上述现有技术中存在的问题,首先,在本实施例中,设置在风道的侧壁上的出风口12沿与进风口11设置方向垂直的方向延伸,以形成一个面积较大的出风口12。即,在本实施例中,出风口12沿风道的宽度方向延伸,且除却连接部13,出风口12的面积与风道的剩余侧壁的面积趋于相等。这样设置的目的在于:在降低气流流速以降低气流形成的噪音的同时,由于出风口12的边棱的减少,气流不会与边棱产生噪音,进一步达到降噪的效果。
并且,为了进一步达到降噪的效果,在本实施例中,出风结构100还设置有与本体1连接的消声组件2。该消声组件2位于风道内气流的流动路径上,以使消声组件2对噪音进行消音,以及消除气流产生的噪音中的尖音部分。并且负压发生器在工作过程中本身也会因振动而产生噪音,该噪音也会有部分传递至出风结构100内。上述设置的消声组件2也可以消除部分负压发生器工作时产生的噪音,从而使得清洁装置在工作排气时产生的噪声较小,且无刺耳的尖音噪音。
至少部分消声组件2设置在风道内,用以阻挡至少部分风道,且至少部分气流经过消声组件2后流出出风口12外,在气流经由消声组件2的过程中,降低气流中所携带的噪音,从而达到消声的效果,使得气流在由出风结构100排出清洁装置外时的噪音较小。
具体的,消声组件2包括第一消声件21,第一消声件21设置在出风口12处,进而使得气流在由出风口12排出出风结构100外时,第一消声件21能与部分气流发生接触,部分气流中的噪音经由第一消声件21的消声处理而降低或消除,之后经过第一消声件21消声处理之后的气流再排出出风结构100外,完成对部分气流的消声处理。
在本实施例中,第一消声件21为消音棉,消音棉的消声效果好,且不阻碍出风,不影响清洁装置的性能,同时消音棉造价便宜,能节约制造成本,后期的更换维护也比较简单。
在其他实施例中,也可根据实际情况选择第一消声件21,如隔音毡等,只要能满足 消声要求皆可,在此不做具体限定。
并且,为了防止第一消声件21对出风结构100的气流流动造成影响,第一消声件21设置在出风口12的部分上,第一消声件21与风道的侧壁之间形成出风支道。在本实施例中,第一消声件21可以根据实际情况设置在出风口12的中部或两侧,在本实施例中,优选的,第一消声件21设置在出风口12的中部。此时,第一消声件21将出风口12分隔成至少两个小的出风口12,即形成两个出风支道,以此将气流分流,同时,对气流进行降噪,以使两侧的气流的降噪效果相等。
在其他实施例中,第一消声件21也可设置在出风口12的两侧。此时,出风口12的数量依然为一个,具体出风口12的数量依据第一消声件21的形状和设置在出风口12的位置而变,在此不做具体限定。
并且,第一消声件21的个数不做限定。例如,在出风口12设置有一个或两个第一消声件21皆可,只需达到上述目的即可。在本实施例中,为了保证出风结构100整体的紧凑,第一消声件21的个数设置有一个。
由前述可知,进风口11沿风道的长度方向上设置,出风口12沿风道的宽度方向设置。因此,为了保证第一消声件21的降噪效果,在出风口12的出风面积不变的情况下,第一消声件21沿风道的长度方向延伸,且沿风道的宽度方向延伸,在保证气流能够通过出风口12顺畅排出至出风结构100外,以尽可能的增加第一消声件21的体积,从而使得第一消声件21能与更多通过出风口12排出出风结构100的气流发生接触,从而增强第一消声件21的降噪效果,并且第一消声件21的设置并不阻碍出风,不影响出风效果。
在其他实施例中,也可根据实际情况选择出风口12与进风口11的延伸方向,如进风口11与出风口12的延伸方向相同,只要能满足出风结构100的出风要求皆可,在此不做具体限定。
具体的,第一消声件21的一端与第一端部14连接,优选的,在本实施例中,第一消声件21的一端与第一端部14的连接方式为搭接,以使得第一消声件21可方便的从第一端部14上取下,使得第一消声件21进行维护更换时更加方便。
具体的,在本体1上还包括与第一端部14连接的限位部15,限位部15设置有至少两个,以使至少两个限位部15与第一端部14之间形成有安装空间。在本实施例中,限位部15设置有两个,以将一个第一消声件21的一端与第一端部14安装固定。
在其他实施例中,限位部15的个数也可为其他,例如三个限位部15,三个限位部15 和第一端部14之间彼此配合以形成两个安装空间,从而可将两个第二消声件21的一端与第一端部14安装固定,在此不做具体限定,限位部15的个数可根据实际设置的第一消声件21的个数而定。
优选的,每个限位部15具有相对设置的顶端151和底端152,底端152为限位部15靠近第一端部14设置的一端,其中,相邻两个限位部15的顶端151之间的直线距离要大于底端152之间的直线距离,以保证限位部15在第一端部14上是相对第一端部14倾斜设置,倾斜方向为沿本体1的高度方向向本体1外倾斜,以防止第一消声件21的一端滑落。并且第一消声件21的第一段211与限位部15相接处具有倾斜面,通过倾斜面与限位部15的配合,使得第一消声件21与第一端部14的连接更为稳定。
在其他实施例中,也可根据实际情况选择第一消声件21与第一端部14的连接方式,如第一消声件21与第一端部14卡持连接,此时第一消声件21与第一端部14中的一个具有卡块,第一消声件21与第一端部14中的另一个具有与卡块相对应的卡槽,通过卡块与卡槽的卡持配合,使得第一消声件21与第一端部14连接,只要能满足第一消声件21与第一端部14的连接要求皆可,在此不做具体限定。
第一消声件21的另一端可以与第二端部16相接,此时,通过第一消声件21与第一端部14和第二端部16的连接作用,将第一消声件21固定设置在出风口12处。
或者,第一消声件21的另一端与第二端部16之间存在间隙,此时,第一消声件21的另一端还需与本体1上的其他部件连接,通过第一消声件21与第一端部14和本体1上其他部件的连接作用,将第一消声件21固定设置在出风口12处。因而,第一消声件21的另一端与第二端部16之间的设置方式可根据实际需求而定,在此不做具体限定。
具体的,第一消声件21包括第一段211、及与第一段211连接的第二段212,第一段211与第一端部14搭接。
在本实施例中,为了简化生产制造工艺,第一段211和第二段212一体成型设置,使得第一段211和第二段212的连接强度更高,进而增强第一消声件21自身的稳定性。
在其他实施例中,也可根据实际情况选择第一段211和第二段212的连接方式,如第一段211和第二段212分开设置,然后通过粘接、紧固件等方式实现连接。只要能满足第一段211和第二段212的连接要求皆可,在此不做具体限定。以通过紧固件连接为例,该紧固件为连接螺栓,通过紧固件的连接作用将第一段211和第二段212连固定连接。
为了进一步增强消声组件2的消声效果,在本实施例中,消声组件2还包括设置在风 道内的第二消声件22,第二消声件22包括一端具有开口221的消音腔222,开口221与进风口11连通以供至少部分风道内的噪音进入消音腔222,该第二消声件22可通过消音腔222来对噪音进行部分消除,尤其针对噪音中的尖音部分消声效果最佳,从而加强消声组件2的消声效果,使得清洁装置在工作排气时产生的噪声中无刺耳的尖音噪音。
在本实施例中,第二消声件22的开口221正向进风口11设置,以使该消音腔222的另一端即为上述的封闭端。消音腔222沿进风口11朝向开口221的方向延伸,以使得自进风口11进入风道的气流能更多的进入至消音腔222内,从而进一步加强第二消声件22的消声效果。
在其他实施例中,也可根据实际情况选择开口221的朝向,如开口221不朝向进风口11设置,此时进风口11与开口221之间还具有导风件,以将部分自进风口11进入风道的气流导向至开口221,在由开口221进入消音腔222内进行消声,只要能满足实际消声要求皆可,在此不做具体限定。
在本实施例中,第二消声件22为1/4波长管,1/4波长管应用驻波理论来消除固定频率噪音中的尖音部分,在开口221处朝消音腔222里传播的声波为入射波,传播到消音腔222内与开口221相对的内壁上会反射回来形成反射波,当入射波和反射波在开口221处的频率和振幅相同、相位相反时,产生干涉相消效应,使得这个频率的波驻留在消音腔222内,无法继续往外传播,从而达到降低这个频率的噪音,消除噪音中的尖音部分。
在其他实施例中,也可根据实际情况选择第二消声件22,如其仅为普通的消音腔222等,只要能满足第二消声件22的消声要求皆可,在此不做具体限定。
在本实施例中,风道内还设置有凸台17,第二消声件22设置在该凸台17上,并且消音腔222与开口221相对的一端与第二端部16相接,以使得第二消声件22在风道内的连接更为稳定,从而保证第二消声件22的消声效果。
在其他实施例中,也可根据实际情况选择第二消声件22在风道内的设置方式,如消音腔222与开口221相对的一端不与第二端部16相接,只要能满足第二消声件22的消声要求皆可,在此不做具体限定。
呈前述,第一消声件21包括第一段211和与第一段211连接的第二段212。其中,第一段211与第一端部14搭接固定,为了保证第一消声件21整体安装的稳定性,在本实施例中,第一消声件21的第二段212与第二消声件22搭接。其中,第二段212具有槽口2121,该槽口2121套设在第二消声件22的外壁上,以将第一消声件21搭接在第二消声件22上, 从而使得第一消声件21通过与第一端部14和第二端部16的连接作用,将第一消声件21固定设置在出风口12上,以保证第一消声件21的消声效果。
本实施例提供了一种清洁装置,适用于对待清洁面进行清洁,请参阅图5至图6所示,清洁装置至少包括负压发生器,以及与负压发生器连接的出风结构100,出风结构100的出风口12与负压发生器的出气口连通,以将负压发生器排出的气流传递至清洁装置外。其中,出风结构100为上述实施例1所阐述的出风结构100。
清洁装置可以为清洁机器人或手持式清洁装置,在本实施例中,该清洁装置为手持式清洁装置。
具体的,清洁装置还包括壳体3,及与壳体3连接的手柄4,负压发生器和出风结构100都设置在壳体3内,通过握持手柄4,可以方便的操作清洁装置以对待清洁面上的污物进行清洁。
壳体3具有气流进口31及与气流进口31连通的气流出口32,气流进口31与负压发生器的进气口连通,以使得外部空气可被负压发生器吸入从而形成气流,对待清洁面上的污物进行吸取清洁。气流出口32与出风结构100的出风口12连通,以让出风结构100的出风口12排出的气流排至清洁装置外。
在本实施例中,气流出口32设置在围设在出风结构100外侧的壳体3的两侧,在其他实施例中,也可根据实际情况选择气流出口32在壳体3上的设置位置,如设置在壳体3的顶部等,只要能满足出风结构100的出风要求皆可,在此不做具体限定。
本实施例提供了一种风机,适用于清洁设备。相对应的,该清洁设备至少设置有用于放置污物的尘盒,风机适于在尘盒内形成负压,以使待清洁面上的污物能够在负压的作用下进入至尘盒内,从而实现对待清洁面的清洁。其中,待清洁面可以为地面、墙面,或者待清洁物体的表面,在此不做具体限定,根据实际情况而定。
具体的,请参照图7至图12,风机包括电机主体模块2′、设置在电机主体模块2′的前端21′的风罩23′、以及罩设在电机主体模块2′和风罩23′外的电机罩1′,电机主体模块2′用于产生气流,从而能够在上述的尘盒内形成负压;风罩23′设置在电机主体模块23′的前端21′,以导向气流的方向和/或使气流聚拢,以达到强负压效果;而电机罩1′则对电机主体模块21′和风罩23′进行保护。
电机主体模块2′还具有相互连通的进风口和出风口,在本实施例中,进风口设置在电机主体模块2′的前端21′,出风口靠近电机主体模块2′的后端22′设置,在风机 工作时,气流自进风口进入,再经由出风口排出,从而实现气流的流动。呈上述,风罩23′设置在电机主体模块2′的前端21′,因此,风罩23′具有与进风口连通的开口,电机主体模块2′运行以使气流通过开口流向至进风口,并自出风口排出。
在其他实施例中,也可根据实际情况选择进风口出风口在电机主体模块2′上的设置位置,如进风口靠近电机主体模块2′的前端21′设置,同时出风口靠近电机主体模块2′的后端22′设置等,只要能满足气流的流动要求皆可,在此不做具体限定。
电机主体模块2′还包括电机主体25′及与电机主体连接的电路板26′,电路板26′设置在电机主体模块2′的后端22′,且与出风口连通,以使气流自出风口流出时,能够对电路板26′进行散热,从而降低电机主体模块2′在运行过程中产生的热量,提高风机整体的使用寿命,同时提高用户体验。电路板26′与电机主体25′连接,以控制电机主体25′执行不同的命令,该电路板26′的控制方法为通过常规的控制电路即可实现,例如在电路板26′的控制芯片内写入控制程序,以控制电机主体25′以不同方向和/或不同转速等进行旋转以实现运行。其中,该控制电机主体25′以不同方向和/或不同转速等进行旋转的控制程序为常规控制程序,本申请并未对控制程序进行相应的改进,故在此不做赘述。
或者,在另一个实施例中,电机主体模块2′包括电机主体25′,该电机主体25′通过电滑环等连接件与外部的电路板26′进行连接,也可实现对电机主体25′的控制,在此不做具体限定,根据实际情况而定。
习知的,电机主体模块2′在运行过程中由于其转速快等原因,会造成电机主体模块2′的振动。电机主体模块2′的振动会传递至风罩23′及电机罩1′上,从而使风机整体振动,继而造成安装有该风机的清洁设备的整体的振动。
因此,为了减小振动,会在电机主体模块2′的两端设置有减震垫,从而缓解电机主体模块2′传递至风罩23′和电机罩1′上的振动。故而,现有技术中,电机主体模块2′的两端分别设置有前减振垫和后减振垫,由前减振垫和后减振垫对电机主体模块2′做两端的夹持,之后再由罩设在外围的电机罩1′进行压紧固定。然而,罩设在电机主体模块2′外侧的电机罩1′与该后端22′相对应的部分的硬度和/或厚度小于电机罩1′的其他部分,电机主体模块2′的振动虽然通过后减震垫的缓解,但是电机罩1′与后端22′相对应的部分非柔性件,既不能减缓振动,同时会致使传递至电机罩1′与后端22′对应的部分上的振动,对电机罩1′与后端22′相对应的部分产生较大的振动,因而造 成电机罩1′本身较大的振动。可见,通过该种固定方式,减振效果较差,从电机主体模块2′传递到整机外壳的振动较大,壳体振动会产生尖音,因而导致清洁设备的壳体噪声较大,用户的使用体验较差。
为了解决上述现有技术中存在的问题,在本实施例中,电机主体模块2′的后端22′悬空在在电机罩1′内,以在后端22′与电机罩1′之间形成有间隙3′,使电机主体模块2′的振动无法传递至电机罩1′上,进而不会造成电机罩1′的振动。同时,在风罩23′和电机罩1′之间设置有减振部件4′,电机主体模块2′传递至风罩23′的振动,经减振部件4′的缓解,传递至电机罩1′与风罩23′相对应的部分时,由于该电机罩1′与风罩23′相对应的部分由于硬度和/或厚度较大,所以引起对该电机罩1′与风罩23′相对应的部分的振动,从而有效缓解电机主体模块2′传递至电机罩1′的振动。相应的,电机罩1′振动减小,其引起的噪音减小,从而提高用户使用体验。
并且,该减振部件4′连接风罩23′与罩设在其外围的电机罩1′,以使风罩23′能够相对于电机罩1′固定,从而将电机主体模块2′与电机罩1′固定连接,以将电机主体模块2′固定在电机罩1′内。由此,电机主体模块2′在工作时不会相对电机罩1′沿电机主体模块2′的轴向方向移动,保证风机整体的有效运行。本申请通过上述设置改进了电机主体模块2′与电机罩1′的固定连接方式,运用改变振动传播介质的方法,使得电机主体模块2′的后端22′与电机罩1′之间存在间隙3′,减少了电机主体模块2′的后端22′传递到电机罩1′上的振动,同时保证了电机主体模块2′与电机罩1′之间相对于固定,进而减小了电机罩1′因振动而产生的噪音,保证用户使用体验。
在本实施例中,减振部件4′为减振垫,减振垫的材质为橡胶或硅胶等,橡胶或硅胶材质的减振垫具有良好的减震阻尼效果,能有效减少电机主体模块2′通过减振垫传递到电机罩1′上的振动。
在其他实施例中,也可根据实际情况选择减振部件4′,如弹性减振件等,只要能满足减振部件4′的减震要求皆可,在此不做具体限定。
优选的,为了进一步增强减振部件4′的减振效果,减振部件4′还具有空腔44′,空腔44′的体积至少占减振部件4′的总体积的50%。由于振动在空气中的传播效果要小于固体的传播效果,从而进一步减小电机主体模块2′传递到电机罩1′上的振动,达到增强减振部件4′的减振目的。
在本实施例中,空腔44′设置有至少两个,两个空腔44′之间互相隔离,通过减 少单个空腔44′体积,增加空腔44′个数的方法来加强减振部件4′的支撑性能,使得减振部件4′在传递振动时不会发生较大的形变,同时还能够保证减振部件4′的减振效果。
在其他实施例中,也可根据实际情况选择空腔44′的设置个数,如空腔44′设置有三个或三个以上等,只要能满足减振部件4′的减震要求皆可,在此不做具体限定。
由前述可知,风罩23′通过减振部件4′与电机罩1′之间固定,进而将电机主体模块2′与电机罩1′之间固定。因此,减振部件4′与电机罩1′、风罩23′之间固定连接。
具体的,减振部件4′具有朝向风罩23′设置的内壁41′,在内壁41′上形成有第一连接部411′,相应的,风罩23′上具有与第一连接部411′连接配合的第一配合部231′,通过第一连接部411′和第一配合部231′的连接配合,以将减振部件4′和风罩23′连接固定。在本实施例中,第一连接部411′与第一配合部231′的连接方式为卡持连接。例如,第一连接部411′和第一配合部231′的其中一个为凹槽,第一连接部411′和第一配合部231′的另一个为与凹槽配合的凸台,通过凹槽与凸台的卡持配合,从而实现减振部件4′与风罩23′的连接。
在其他实施例中,也可根据实际情况选择第一连接部411′与第一配合部231′的连接方式。如第一连接部411′与第一配合部231′的连接方式为通过连接件进行连接,此时风机还包括连接件,第一连接部411′和第一配合部231′皆为连接孔,通过连接件贯穿安装在第一连接部411′和第一配合部231′的连接孔内,从而实现减振部件4′与风罩23′的连接,只要能满足减振部件4′和风罩23′的连接要求皆可,在此不做具体限定。其中,上述的连接件可以为螺栓等。
减振部件4′还具有与内壁41′相对设置的外壁42′,即,该外壁42′朝向电机罩1′设置。同样的,在外壁42′上形成有第二连接部421′,相应的,电机罩1′具有与第二连接部421′连接配合的第二配合部11′,通过第二连接部421′和第二配合部11′的连接配合,以将减振部件4′和电机罩1′连接固定,进而将电机主体模块2′与电机罩1′进行连接固定,从而使得电机主体模块2′在工作时不会相对电机罩1′移动。
在本实施例中,第二连接部421′与第二配合部11′的配合方式为抵接配合,在减振部件4′与电机罩1′安装时相接时,通过第二连接部421′和第二配合部11′的抵 接配合,从而将减振部件4′和电机罩1′连接固定。
具体的,第二连接部421′具有抵接面4211′,第二配合部11′远离前端21′的一端与该抵接面4211′抵接。减振部件4′具有第一凸部43′,该第一凸部43′与减振部件4′的其余部分形成有台阶,台阶靠近前端21′的一侧具有台阶面,该台阶面作为上述抵接面4211′。在电机罩1′上还形成有与抵接面4211′抵持的抵接体12′,该抵接体12′作为上述的第二配合部11′。
由此可见,前述第一连接部411′和第一配合部231′的配合防止电机主体模块2′沿电机主体模块2′轴向和径向的移动,第二连接部421′和第二配合部11′的配合则进一步防止电机主体模块2′轴向和径向的移动,从而保证电机主体模块2′相对于电机罩2′固定。
在其他实施例中,也可根据实际情况选择第二连接部421′与第二配合部11′的连接方式,如第二连接部421′与第二配合部11′的连接方式为卡持连接,此时第二连接部421′和第二配合部11′的其中一个为凹槽,第二连接部421′和第二配合部11′的另一个为与凹槽配合的凸台,通过凹槽与凸台的卡持配合,从而实现减振部件4′与电机罩1′的连接,只要能满足减振部件4′和电机罩1′的连接要求皆可,在此不做具体限定。
有前述可知,风罩23′安装于电机主体模块2′的前端21′处,为了进一步防止所述风罩23′沿电机主体模块2′轴向产生位移,在本实施例中,电机主体模块2′的外侧面还形成有第一止位件24′,风罩23′安装在电机主体模块2′的前端21′之后,风罩23′远离前端21′的一端与第一止位件24′相抵持,进而实现限制风罩23′的位移,从而限制电机主体模块2′的位移。
为了方便电机罩1′和减振部件4′之间的装配安装,在本实施例中,电机罩1′包括外壳本体13′及与外壳本体13′卡持的卡扣14′,抵持体12′形成在卡扣14′远离前端21′的一端。外壳本体13′朝向卡扣14′设置的一面形成有第二凸部131′,第二凸部131′靠近台阶面设置,且与台阶面之间形成有卡持空间,卡扣14′远离前端21′的一端形成有朝向外壳本体13′设置的凸块141′,该凸块141′与卡持空间相卡持,以将卡扣14′与外壳本体13′和减振部件4′相固定。其中,为了方便生产制造工艺,上述的凸块141′与抵持体12′一体成型设置。在其他实施例中,凸块141′和抵持体12′之间也可分体设置后进行粘接、紧固件连接等,在此不做具体限定,根据实际情况 而定。
电机罩1′和减振部件4′在安装连接时,可先进行减振部件4′和外壳本体13′的安装,之后再安装卡扣14′,来完成电机罩1′和减振部件4′的安装连接,进而使得电机罩1′和减振部件4′在安装时更加方便简单。
在其他实施例中,也可根据实际情况选择外壳本体13′和卡扣14′的连接方式,如外壳本体13′与卡扣14′一体成型设置,只要能满足电机罩1′和减振部件4′的连接要求皆可,在此不做具体限定。
为了方便卡扣14′与外壳本体13′安装连接时的定位和对卡扣14′进行限位,在本实施例中,卡扣14′还设置有第二止位件142,在卡扣14′与外壳本体13′连接时,第二止位件142与外壳本体13′靠近前端21′的一端相抵持,从而将卡扣14′相对外壳本体13′进行限位,也能方便卡扣14′与外壳本体13′安装连接时进行定位。
风机在工作时,会有大量热量由电机主体模块2′产生,为了方便电机主体模块2′的散热,在本实施例中,电机罩1′的外壳本体13′上还设置有若干散热孔,使得电机主体模块2′工作时产生的热量可以通过散热孔散至风机外,从而避免因风机内部热量堆积过多而损坏电路板和其他部件,加强风机的整体使用寿命。
为了避免减振部件4′阻挡住出风口而影响风机的出风,在本实施例中,减振部件4′的长度要小于电机主体模块2′的出风口至进风口的长度,该长度的丈量方向为电机主体模块2′的前端21′自后端22′的方向,从而使得减振部件4′不会因长度过长而阻挡住电机主体模块2′的出风口,影响风机出风。
风机还包括有壳体5′,壳体5′具有进气口以及与进气口连通的出气口,电机主体模块2′设置在壳体5′内,电机主体模块2′的进风口与壳体5′的进气口连通,出风口与出气口连通,以使得外部的空气能被风机由进气口吸入,再由出气口排出,从而实现风机的正常工作。
本实施例提供了一种清洁设备,适用于对待清洁面进行清洁,该清洁设备可以为清洁机器人或手持式清洁设备,在此不做具体限定。
清洁设备至少包括风机、以及与风机的进气口连接的清洁附件,清洁附件适于对待清洁面进行清洁,风机则产生负压将待清洁面上的污物给吸入。其中,风机为上述实施例1所阐述的风机。
为了保证清洁设备的清洁效果,清洁设备还包括连接风机和清洁附件的尘盒,尘盒 具有进尘口和出尘口,进尘口与清洁附件连接,出尘口与风机的进气口连通。
显然,上述所描述的实施例仅仅是本申请一部分的实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下,可以做出其它不同形式的变化或变动,都应当属于本申请保护的范围。
