一种通过离心风扇传动的风动毛绒修剪器 技术领域
本发明涉及小家电领域，特别涉及一种通过离心风扇传动的风动毛绒修剪器。
背景技术
现阶段市场上的毛绒修剪器一般都通过电动马达提供动力，电动马达的高速旋转带动刀片进行切割，切割下来的毛绒在马达叶轮的作用下甩出进入对应的集绒盒内，这种电动毛绒修剪器需要频繁充电，机器内部残留毛绒较多。此外，市场上还有一种风动毛绒修剪器，这种毛绒修剪器是将刀片固定在六叶或者更多叶片的风轮上，通过连接高风量的真空吸尘器带动风轮高速转动，形成最终的切割效果，这种形式的毛绒修剪器受限于大风量的真空吸尘器，当配合的真空吸尘器风量较小时，往往达不到预期的效果。
有鉴于此，实有必要开发一种通过离心风扇传动的风动毛绒修剪器，用以解决上述问题。
发明内容
针对现有技术中存在的不足之处，本发明的目的是提供一种通过离心风扇传动的风动毛绒修剪器，其在低风量的真空吸尘器的带动下也能正常运转，在同样风量条件下具有更好的毛绒修剪效果。
为了实现根据本发明的上述目的和其他优点，提供了一种通过离心风扇传动的风动毛绒修剪器，包括：机体及可拆卸地安装于机体内的毛绒修剪刀盘，其特征在于，所述机体包括壳体组件，该壳体组件包括中空的壳体及设于壳体内的毛绒修剪室与风轮室，风轮室与毛绒修剪室依次间隔设置。
优选的是，壳体组件包括离心风扇，毛绒修剪刀盘设置于毛绒修剪室内，离心风扇设于风轮室中。
优选的是，所述风轮室的顶部设有动力风道，所述毛绒修剪室设有吸绒风道。
优选的是，所述壳体在其前后两端敞开以形成分别位于前后两端的前端口及后端口，所述后端口处连接有抽风风道，所述动力风道与所述吸绒风道在所述壳体的内部沿所述壳体的长度方向延伸，所述动力风道与所述吸绒风道汇流后最终与所述抽风管道相连通。
优选的是，所述动力风道的内壁上设有竖直向下突出的风扇旋转轴柱，所述风扇旋转轴柱上设有轴顶，所述离心风扇的旋转中心处设有贯穿所述离心风扇的风扇旋转主轴，所述风扇旋转主轴的顶端与所述轴顶相抵。
优选的是，所述风扇旋转主轴的底端与所述毛绒修剪刀盘传动连接。
优选的是，所述壳体的前端设有通往所述风轮室的若干个动力风道进风口。

具体实施方式
下面结合附图对本发明做进一步的详细说明，本发明的前述和其它目的、特征、方面和优点将变得更加明显，以令本领域技术人员参照说明书文字能够据以实施。在附图中，为清晰起见，可对形状和尺寸进行放大，并将在所有图中使用相同的附图标记来指示相同或相似的部件。在下列描述中，诸如中心、厚度、高度、长度、前部、背部、后部、左边、右边、顶部、底部、上部、下部等用词为基于附图所示的方位或位置关系。特别地，“高度”相当于从顶部到底部的尺寸，“宽度”相当于从左边到右边的尺寸，“深度”相当于从前到后的尺寸。这些相对术语是为了说明方便起见并且通常并不旨在需要具体取向。涉及附接、联接等的术语(例如，“连接”和“附接”)是指这些结构通过中间结构彼此直接或间接固定或附接的关系、以及可动或刚性附接或关系，除非以其他方式明确地说明。
参照图1及图3，通过离心风扇传动的风动毛绒修剪器包括：
机体1及可拆卸地安装于机体1上的毛绒修剪刀盘2，机体1包括中空的壳体11及形成于壳体11内的毛绒修剪室13与风轮室14，毛绒修剪室13与风轮室14被间隔开来。
所述壳体组件1还包括设置于风轮室14内的离心风扇3，毛绒修剪刀盘2安装于所述毛绒修剪室13内。
参照图1及图3，壳体11的外壁设有若干个通往风轮室14的动力风道进风口113。
进一步地，毛绒修剪室13与风轮室14间隔设置，风轮室14的顶部设有动力风道121。动力风道121与离心风扇3以及壳体11的进风口113连通并将其相对壳体内部密封，风轮室14与动力风道进风口113相对一侧处开设有 若干个沿周向分布的进风槽142，相邻两个进风槽142之间设有延伸至动力风道进风口113处的进风挡板141，相邻两片进风挡板141间隔设置以形成位于进风挡板141间的进风通道，从而使得从动力风道进风口113吸入的空气能够在进风通道的整流作用下，平滑、顺畅地进入到风轮室14内。
进一步地，动力风道121的顶部内侧设有竖直向下突出的风扇旋转轴柱1211，风扇旋转轴柱1211上设有轴顶32，离心风扇3的旋转中心处设有贯穿离心风扇3的风扇旋转主轴31，该风扇旋转主轴31的顶端与轴顶32相抵。进一步地，风扇旋转主轴31设有向下贯穿延伸入毛绒修剪室13的风扇输出轴孔131，离心风扇3通过风扇输出轴孔131与毛绒修剪刀盘2传动连接。在优选的实施方式中，风扇旋转主轴31与风扇输出轴孔131间持续密封，毛绒修剪室13设有连通吸绒风道122的吸绒进风口132。
进一步地，后端口112处连接有抽风风道12，动力风道121与吸绒风道122在壳体11的内部沿壳体11的长度方向延伸，动力风道121与吸绒风道122汇流后最终与抽风管道12相连通。可将本发明所述的双风道结构的风动毛绒修剪器1通过抽风管道12与吸尘器的抽风口相连接，从而对吸尘器的功能进行扩展。
离心风扇3在动力风道121中的流动的空气作用下，将风能转化成机械能，并通过风扇输出轴将机械能传递给毛绒修剪刀盘2，从而实现对毛绒进行修剪。将原先用于同时提供风能及吸绒风力的风道一分为二，两个风道互不连通，使得两个风道互不干涉，清洁效率更高，并且避免了使用一段时间后风扇由于缠绕过多毛绒需要定期清理的问题。
进一步地，壳体11的前端竖直向下延伸以使得壳体11大致呈“L”形结构。
风轮室在优选的实施方式中，壳体11从前置后呈逐渐缩小之势，从而增大了毛绒修剪室13与风轮室14的容积，增加了进风量及修剪效率，同时，壳体11较小的后端便于操作人员持握。
进一步地，壳体11的侧壁上开设有连通动力风道121的风量调节口161，风量调节口161的旁侧滑动地设有可对风量调节口161进行选择性遮蔽的风量调节档板16。
使用时，本发明所述风动毛绒修剪器的抽风管道12连接至具有真空抽吸作用的主机，在主机的抽吸作用下，气流自壳体11的动力风道进风口113进入风轮室14内，再流向动力风道121内，吹动离心风扇3旋转以带动毛绒修剪刀盘2进行工作，经过毛绒修剪刀盘2剪下的绒毛，在抽风管道12的吸力下，自吸绒进风口132进入吸绒风道122中并与动力风道121汇集至抽风管道12被主机抽走。
这里说明的设备数量和处理规模是用来简化本发明的说明的。对本发明的应用、修改和变化对本领域的技术人员来说是显而易见的。
尽管本发明的实施方案已公开如上，但其并不仅限于说明书和实施方式中所列运用，它完全可以被适用于各种适合本发明的领域，对于熟悉本领域的人员而言，可容易地实现另外的修改，因此在不背离权利要求及等同范围所限定的一般概念下，本发明并不限于特定的细节和这里示出与描述的图例。
