Description

树叶清理装置 技术领域
本发明涉及一种电动工具,尤其是一种树叶清理装置。
背景技术
随着城市绿化面积的不断扩大,公园、公路、公共场所的绿化带遍及全国各地,草坪修整工具也被广泛的应用,树叶清理装置就是其中一种,主要用于打理散落在草坪上的树叶。
树叶清理装置具有进风口和出风口,通过进风口树叶清理装置可以将草坪上散落的树叶吸入机器内部,同时树叶清理装置内部设置有高速旋转的刀片,旋转的刀片会将吸入树叶清理装置内部的树叶打碎,打碎的树叶在气流的带动下最终会从树叶清理装置的出风口排出。一般情况下,用户会在树叶清理装置的出风口接入树叶收集袋,这样通过树叶清理装置吸入的树叶经刀片打碎后最终收集在树叶收集袋中,用户将树叶收集袋中的粉碎后的树叶进行倾倒,从而完成了一次完整的树叶清理工作。
目前所使用的树叶清理装置中,有一部分树叶清理装置是手持形式。使用手持形式的树叶清理装置时,树叶清理装置通常会在出风口配接一个树叶收集布袋,用户需要背着树叶收集布袋并一直握持树叶清理装置在草坪上行走以清洁散落在草坪上的落叶。树叶收集袋背负在用户身上会造成用户身上沾有很多灰尘,更重要的是,当用户需要清理的草坪较大,散落的树叶较多时,用户需要一直长时间握持树叶清理装置进行清理作业,用户的负担较重,很容易造成疲劳。
还有另一部分手推式树叶清理装置。这部分手推式树叶清理装置通常设置有一对轮子,还有相应的供用户握持的一对把手,用户握持把手通过轮子推动树叶清理装置在草坪上移动从而将草坪上散落的树叶吸入并通过刀片打碎,最终从出风口排出并通过树叶收集袋进行收集。
手推式树叶清理装置需要用户一直握持把手并不断通过调节手臂的姿势从而实现调节树叶清理装置进风口的位置来提高吸取草坪上树叶的效率。同样当需要清理的草坪面积很大,散落的树叶较多时,用户需要一直握持把手推动树叶清理装置进行清理操作,用户负担较重,同样很容易造成疲劳。
而且现有的这些树叶清理装置的进风口通常设置成贴近地面,进风口的离 地间隙比较小,类似家用吸尘器的结构,但是该种结构的进风口吸取地面上的树叶面积有限,导致工作效率比较低下。因此期待一种可以放置在地面上使用,且吸叶效率较高的树叶清理装置。
另外,该类的手推式树叶清理装置的进风口通常呈扁平形状,类似日常吸尘器的吸嘴,该种进风口的开口面积较小,并不利于高效吸入树叶,而且树叶需要通过较为狭长的通道才能被刀片粉碎,因此整体的清理树叶效率并不高。有必要对此进行改进。

具体实施方式
下面结合附图对本发明的较佳实施例进行详细阐述,以使本发明的优点和特征能更易于被本领域技术人员理解,从而对本发明的保护范围做出更为清楚明确的界定。
本发明中所谈及的上、下、垂直等方位词语都是以树叶清理装置放置在地面进行吸叶、碎叶时的状态为参照的。上是指远离地面,下是指靠近地面,如无特别说明,下文中所涉及的上、下等位置的描述均以此处的说明为准。
图1至图3示出了本发明第一实施例的树叶清理装置200。树叶清理装置200包括壳体10,进风口30设置在壳体10上,树叶从进风口30进入壳体10的内部。壳体10内部还设置有电机40。树叶清理装置200还包括碎叶装置50,碎叶装置50由电机40驱动绕一轴线旋转用于将从进风口30吸入的树叶打碎。树叶清理装置200还包括设置在壳体10上的出风口60,气流和经碎叶装置50 打碎的树叶从出风口60排出。树叶清理装置200包括支撑在地面上的支撑部70。如图1所示,支撑部70位于壳体10上,并且支撑部70靠近进风口30设置。当需要使用树叶清理装置200时,使支撑部70稳定地支撑在地面上。用户可以轻松地解放双手,无需扶持树叶清理装置1。当支撑部70受到地面支撑时,出于高效吸入树叶的目的,进风口30靠近地面且进风口30的朝向与地面之间呈一夹角,该夹角小于60度。这样可以保证地面上的树叶可以快速的进入进风口30,同时由于夹角的存在,使得位于进风口30附近地面上的大面积树叶都可以被吸入进风口30。
进风口30还具有一贯穿进风口30的法线31,该法线31沿进风口30的朝向延伸。因此,当支撑部70受到地面支撑时,该法线31与地面之间呈小于60度的夹角。当然,支撑部70定义一支撑平面P,如图1所示,该支撑平面P基本呈水平放置,树叶清理装置200位于该支撑平面P之上。进风口30定义一进风平面Q,树叶及空气穿过该进风平面Q进入至壳体10的内部。值得注意的是,支撑平面P与进风平面Q的夹角大于30度,而在优选的实施例中最大为90度,此时支撑平面P与进风平面Q相互垂直。
在图1所示的优选实施例中,进风口30的朝向与地面的夹角为0度,即进风口30的朝向与地面平行,而法线31与地面之间的夹角为0度,支撑平面P与进风平面Q的夹角为90度。
壳体10包括电机收容壳12、蜗壳14、第一延伸部16和第二延伸部18。电机收容壳12由两半壳构成,两半壳拼接之后中间形成收容电机40的中空部。电机40竖直方向设置在电机收容壳12的内部,电机40的输出轴42的方向与地面垂直。电机40的输出轴42上同轴设置有散热风扇44,散热风扇44的设置用于对电机40旋转时产生的热量进行散热处理。
蜗壳14内部为圆形弧面设计,这样的设计有利于降低风阻和形成流畅的气流通道。蜗壳14已经广泛的应用在电动工具领域,如吹风机、割草机等,蜗壳14具体的工作原理等在此就不再详细描述。蜗壳14可以由透明的材质制成,透明材质制成可以保证在树叶清理装置200工作时,用户可以观察到碎叶装置50的运转状态,从而用户可以很容易避免触碰到碎叶装置50,最终保证了用户的操作安全。蜗壳14的上端中心部位设置有开口,电机输出轴42从中心部位 开口伸入到蜗壳14内部。
树叶清理装置200的壳体10包括第一延伸部16和第二延伸部18。第一延伸部16位于进风口30与蜗壳14之间,用于引导空气和树叶从进风口30进入至蜗壳14。蜗壳14下端中心部位同样设置有开口,第一延伸部16一端在蜗壳14下端中心开口处与蜗壳14连通,从而使得第一延伸部16的第一端连接蜗壳14的中心。第一延伸部16相对的另一端,即第一延伸部16的第二端连接进风口30。在优选的实施例中,第一延伸部16的第一端和第二端的水平距离小于30cm,如此可以保证树叶从进风口30移动至蜗壳14中心过程中较小的通过距离,不会产生堵塞在第一延伸部16的情况。在优选的实施例中,第一端和第二端的水平距离为小于20cm。第二延伸部18一端与蜗壳14连通,相对的另一端为出风口60。
本实施例中蜗壳14下端中心开口处和第一延伸部16连通的截面为圆形,本领域技术人员可以想象的是连通截面的形状并不限于圆形,其他可以实现供气流流通的任意形状的通道截面都在本发明的保护范围之内。本实施例中电机40的输出轴42所在的直线与蜗壳14上端开口的中心线、蜗壳14下端开口中心线和第一延伸部16与蜗壳14连通端的中心线重合,并且都与地面垂直。
请参见图4,蜗壳14内部,电机40的输出轴42末端设置有碎叶装置50。本实施例中碎叶装置50包括圆形的转动盘51,转动盘51周向设置有安装凸起52及导引槽53。碎叶装置50包括用于将吸入树叶清理装置200内部的树叶打碎的刀片54。刀片54通过与安装凸起52配合安装固定到转动盘51上,刀片54的其余部分从导引槽53延伸到转动盘51的主体之外。
碎叶装置50还包括与转动盘51配接的安装盖55。当刀片54通过安装凸起52和导引槽53安装到转动盘51后,将安装盖55与转动盘51配接,从而最终将刀片54牢固地固定到转动盘51上。转动盘51和安装盖55可以通过快拆的方式实现快速装配和快速拆卸,本领域技术人员可以想象的是,快拆的方式很多,包括但不限于通过卡扣等方式。转动盘51和安装盖55的中心部位都设有开口,开口可与电机40的输出轴42相配接,从而将电机40的转动传递到转动盘51,从而最终带动刀片54将进入树叶清理装置200的树叶打碎。
优选的实施例中刀片54为柔性件。这样可以减少对用户造成潜在的伤害。 在本实施例中,刀片54为弹性尼龙绳,尼龙绳的数量为6股,在其他的实施例中,尼龙绳的数量还可以是其他的数量,并不限于本实施例中所采用的6股。尼龙绳通过安装凸起52安装固定到转动盘51上,尼龙绳的其余部分通过导引槽53引出到转动盘51之外。电机40驱动转动盘51旋转,转动盘51旋转带动尼龙绳旋转从而将进入树叶清理装置200的树叶打碎。
(A3445-1)如图5所示,本发明的另一实施例的碎叶装置50包括安装盖55和转动盘51。碎叶装置50设置在树叶清理装置200中,碎叶装置50用于安装刀片54。在本实施例中,刀片54可以采用尼龙绳。需要说明的是,刀片54也可以为麻绳、凯夫拉绳等。
再参考图6,安装盖55包括第一表面111,第一表面111上开设有缝112,缝112延伸至第一表面111的边缘。缝112用于卡住刀片54。在本实施例中,安装盖55的形状为圆柱体。缝112的数量为四,且四条缝112呈对称分布。
此外,参考图5,安装盖55还包括第二表面113,第二表面113与第一表面111相对。由上述可知,安装盖55的形状为圆柱体,第一表面111和第二表面113位于圆柱体相对侧。第二表面113上开设有第一凹槽114。在本实施例中,第一凹槽114的数量为四个,且四个第一凹槽114呈对称分布。
第一凹槽114的底面上开设有第一通孔115和第二通孔116,如图6所示。第一通孔115和第二通孔116分别用于穿过刀片54的一个端,也就是说,刀片54的两个端分别穿过第一通孔115和第二通孔116,从而刀片54变成两股,如图7所示,穿过第一通孔115和第二通孔116的刀片54卡在缝112中。因此,刀片54固定在安装盖55中。
参考图6和图7,在本实施例中,缝112位于第一通孔115第二通孔116之间的位置,从而穿过第一通孔115和第二通孔116的刀片54能正对着卡在对应的缝112中。需要说明的是,缝112也可以开设在其他位置,通过第一通孔115和第二通孔116的刀片54卡在最接近的缝112中即可。
将刀片54卡在开设在安装盖55的第一表面111上的缝112后,需要将安装盖55和转动盘51连接。具体地,参考图5,转动盘51上开设有第四凹槽511,转动盘51的开设有第四凹槽511的表面与安装盖55的第一表面111接触连接。 从而使得刀片54能更好地固定在安装盖55和转动盘51之间。且树叶清理装置200中的电机与第四凹槽511的底部连接,电机带动转动盘51转动
此外,安装盖55与转动盘51可拆卸连接。在本实施例中,安装盖55与转动盘51相互卡接。如图6所示,安装盖55上设有凸出部117,凸出部117从第一表面111的边缘延伸出来。再参考图5,转动盘51的外表面上开设有第三凹槽512,第三凹槽512与凸出部117相匹配,其中转动盘51的外表面为转动盘51的圆周侧表面。
在本实施例中,凸出部117的数量为两个,且两个凸出部117呈对称分布,从而相对应地,安装盖55的外表面上开设有两个第三凹槽512,且两个第三凹槽512也呈对称分布。需要说明的是,凸出部117的数量也可以为一个、三个或以上等,可以根据实际需要进行设置。
需要说明的是,安装盖55与转动盘51之间也可以通过其他方式可拆卸连接,如扣接等。
此外,在本实施例中,为了刀片54工作时能更好地固定,不发生移位。如图5所示,在第四凹槽511的底部上设有限位板513,限位板513从第四凹槽511的底部延伸出来,且限位板513与第四凹槽511的内壁接触连接。
为了更好地对刀片54起到限位的作用,在本实施例中,限位板513的宽度与缝112的宽度相同,从而当安装盖55和转动盘51连接时,限位板513和缝112相卡接,使得刀片54很好地卡在缝112中。其中,限位板513的宽度为限位板513的在与第四凹槽511的内壁垂直的方向上的宽度。需要说明的是,限位板513的宽度也可以小于缝112的宽度。
在本实施例中,第四凹槽511的底部开设有第四通孔514,第四通孔514的内壁沿着第四通孔514的轴向方向延伸,形成空腔515。树叶清理装置200的电机40的输出轴前端可以穿过第四通孔514,并通过螺母与转动盘51固定连接,电机40驱动转动盘51同步运动。
在本实施例中,限位板513的宽度为空腔515的外壁与第四凹槽511的内壁之间的距离,也就是说,限位板513设置在第四凹槽511的内壁和空腔515的外壁之间。
在其他实施例中,刀片54也可以采用其他方式卡在缝中。安装盖55的第一表面111上可以开设第二凹槽,第二凹槽的内壁上开设有第三通孔,从而刀片54的一端可以依次穿过第三通孔,进而刀片54卡在缝中。
此外,缝112也可以从延伸至第一表面111的两个相对的边缘,刀片54直接卡在该缝112中。
通过将刀片54卡在碎叶装置50中,而碎叶装置50设置在树叶清理装置200中,当需要更换刀片54时,只需将碎叶装置50取出来,就可以实现刀片54快速更换。
如图8所示,一实施例的树叶清理装置200包括碎叶装置50、刀片54、进风口30、蜗壳14、电机40以及树叶收集袋120。进风口30与蜗壳14的一侧连接,碎叶装置50设置在蜗壳14内,电机40与蜗壳14的另一侧连接,电机40的前端与转动盘51连接,电机40带动转动盘51转动,刀片54安装在碎叶装置50中。
具体地,蜗壳14包括上壳410和下壳420,进风口30与上壳410连接,碎叶装置50设置在上壳410和下壳420之间。电机40与下壳420固定连接,电机40的轴依次穿过下壳420以及开设在转动盘51上的第四通孔514。树叶收集袋120与蜗壳14可拆卸连接。电机40的输出轴前端穿过第四通孔514,并通过螺母与转动盘51固定连接。
从而当树叶清理装置200工作时,电机40高速旋转,电机40的轴驱动碎叶装置50及刀片54一起高速旋转。树叶等从进风口30进入蜗壳14,被高速旋转的刀片54粉碎,粉碎后的树叶在离心力的作用下进入树叶收集袋120。
请参见图9,图9是另一实施例中的碎叶装置80。本实施例中碎叶装置80包括转动盘82和刀片84,刀片84固定安装在转动盘82上,转动盘82上设置有与电机40的输出轴42配接的安装部86。同样的,电机40驱动转动盘82旋转,转动盘82旋转带动刀片84旋转从而将进入树叶清理装置200的树叶打碎。
如下将对本实施例中碎叶装置80与图4所示的实施例中的不同之处进行详细描述。请参见图10,图10是图9中刀片沿剖切面A剖切后的示意图。图10中A-A为刀片84的旋转平面,为了使刀片84达到理想的打碎树叶的效果,刀 片84所在的平面与刀片84的旋转平面所呈的刀片夹角α的大小为0~30°。优选的,当刀片夹角α为5°时,刀片84对进入树叶清理装置200的树叶的打碎效率得到了明显的提升。
请参见图11,图11是另一实施例中的碎叶装置90。碎叶装置90包括转动盘91和刀片92。转动盘91的周向接近边缘位置均匀地布置有若干个连接轴93。刀片92与连接轴93连接,并且刀片92可以垂直于连接轴93的轴线方向进行转动。在本实施例中连接轴93的数量为4个,相应的,刀片92的数量也是4个。本领域技术人员可以想象的是,在其他的实施例中连接轴93的数量可以小于4个,也可以比4个更多,即刀片92的数量可以设置为大于0的任意数量,凡是只要是可以实现对进入树叶清理装置内的树叶进行打碎的连接轴93的布置数量都属于本发明的保护思想,都在本发明的保护范围之内。
碎叶装置90还包括与转动盘91配接的安装盖94。刀片92安装到连接轴93后,将安装盖94与转动盘91相配接,从而固定刀片92,限制刀片92沿连接轴93上下方向上的移动。安装盖94中心部位设置有与电机40的输出轴42配接的安装部95。电机40驱动转动盘91进行转动,刀片92由于转动盘91的转动产生的离心力作用,向转动盘91的四周延伸。
换言之,刀片92由于离心力的作用,刀片92的长度方向的延长线通过转动盘91的中心位置,当刀片92打到树叶时,由于刀片92高速运动,树叶被刀片92打碎。与此同时,由于树叶对刀片92产生力的作用,刀片92会以连接轴93为圆心进行转动,进而对刀片92起到缓冲的作用。这样的设计,可以有效防止由于刀片92的转速过高,造成刀片92的损坏。
进一步的,为了降低打碎树叶时对刀片92的损害,刀片92的材质可以选择具有一定韧性的弹性材质。当刀片92打到树叶时,由于刀片92为柔性弹性材质,刀片92由于力的作用便会产生一定的形变,这样对刀片92有一定的缓冲作用,避免了刀片92的损坏。
请参见图12,图12是另一个实施例中的碎叶装置100。碎叶装置100包括转动盘101和安装在转动盘101上的刀片102。刀片102包括一对切割刃104和一对翻边106,切割刃104是为了对进入树叶清理装置200内部的树叶进行粉碎,而翻边106的设置是为了增强刀片102旋转时所产生的风力,以获得更 好的切割粉碎的效果。转动盘101上设置有与电机40的输出轴42配接的安装部108。电机40驱动刀片102旋转从而将进入树叶清理装置200内的树叶打碎。本实施例中,刀片102采用的是金属材质,金属材质的刀片102更加的坚固和耐磨损,可以获得更长的使用寿命。
以上列出了粉碎装置的几种实施例,但这并不是对本发明粉碎装置保护范围的限制,本发明的粉碎装置包括但不限于以上所列出的粉碎装置的几种实施例。本领域技术人员可以想象的是粉碎装置还有其他的一些实施方式,凡是可以实现将进入树叶清理装置200内的树叶进行粉碎的粉碎装置都属于本发明的保护思想,都在本发明的保护范围之内。
树叶清理装置200通过进风口30将树叶吸入到树叶清理装置200内部并通过碎叶装置进行粉碎,最终通过树叶清理装置200的出风口60排出。本实施例中,粉碎装置具有两个功能:1、旋转产生风力,从而带动气流从树叶清理装置200的进风口30进入树叶清理装置200的内部,并从树叶清理装置200的出风口60排出。2、将从进风口30进入树叶清理装置200内部的树叶打碎。
粉碎装置旋转产生风力从而带动气流从进风口30进入树叶清理装置200内部,树叶在气流的带动下进入树叶清理装置200内部。树叶在壳体10内部被粉碎装置打碎,打碎的树叶在粉碎装置旋转产生风力带动的气流的引导下转动到出风口60,并最终从出风口60排出。总的来说,粉碎装置可以将进入壳体10内的树叶打碎,还可以旋转产生气流从树叶清理装置200的进风口30进入壳体10内部,并从出风口60排出。
本实施例中,粉碎装置同时具有旋转产生吸入树叶的气流和粉碎树叶的双重功能。在其他的实施例中可以通过分别设置两个装置来实现本实施例中粉碎装置的作用。其中一个装置只具有使气流从树叶清理装置200的进风口30进入树叶清理装置200内部,并从出风口60排出的作用,举例来说如离心式风扇等;而另一个装置只具有将吸入树叶清理装置200的内部的树叶进行粉碎的功能。当然了,也可以设置为一个装置只具有粉碎树叶的功能而相应的另一个装置兼具有粉碎树叶和产生气流双重作用。本领域技术人员可以想象的是,除以上列出的几种方式外,还可以有其他的组合方式来实现粉碎树叶和产生气流,凡是可以实现粉碎树叶和产生气流双重功能并且不变离本发明核心构思的实现方式 都在本发明的保护范围之内。
树叶清理装置200的最基本的功能就是将树叶吸入树叶清理装置200的内部,并将吸入的树叶进行粉碎,最终将粉碎的树叶从出风口排出。只要是可以实现树叶清理装置200的基本功能,粉碎树叶的装置、产生吸入风力的装置怎么布局,设置的装置的数量、形式等都没有严格的限定,都在本发明的保护范围之内。
如下内容将对本发明中树叶清理装置200的工作原理及优化设计进行详细的描述。用户使用树叶清理装置200对草坪的落叶进行清理,用户可以通过支撑部70将本发明的树叶清理装置200放置在地面上进行落叶清理作业,从而避免了一般树叶清理装置需要手持进行操作的工作负担。本发明中,支撑部70为树叶清理装置200工作时,第一延伸部16与地面接触的部分。在其他的实施例中,还可以额外在树叶清理装置200之外设置单独的支撑部件。
启动树叶清理装置200,电机40通电转动从而驱动与之连接的碎叶装置进行转动,碎叶装置转动带动气流从树叶清理装置200的进风口30进入机器内部,经碎叶装置打碎后并最终从树叶清理装置200的出风口60排出。因本发明中树叶清理装置200是放置在地面上使用的,因此草坪上树叶清理装置200周边的树叶清理时,用户可以借助耙子等一些辅助设备先将树叶清理装置200周边的落叶移动到接近树叶清理装置200的进风口30并在气流的作用下最终进入树叶清理装置200内部被粉碎并从树叶清理装置200的出风口60排出。当然在其他的实施例中叶可以不借助气流,而直接用耙子等辅助工具将草坪的树叶推入树叶清理装置200的内部,并最终从树叶清理装置200的出风口60排出。
请参见图1和图13,树叶从进风口30进入树叶清理装置200内部,为了保证树叶可以顺利从进风口30进入树叶清理装置200的壳体10内部,进风口30的风口面积S1大于260平方厘米,进一步地,进风口30的风口面积S1不大于800平方厘米。这样可以保证在一定时间内有足够多的树叶被吸入壳体中,从而提升树叶的粉碎效率,在最优的实施例中,进风口30的风口面积S1为500平方厘米左右。在本实施例中,进风口30具有矩形的开口形状,其具有风口长度L和风口高度H。通过实验验证,进风口30的风口长度L与风口高度H的比值范围为大于0.5并且小于2时,树叶通过进风口30的效率较高。在优选的 实施例中,风口长度L优选为240mm,而风口高度H优选为160mm,这样风口的长度和高度的比值约为1.5。当然也可以把进风口30旋转90度设置,这样长度变为160mm,高度变为240mm,如此风口的长度和高度之比大约为0.67。这样的风口面积S1数值的设定和进风口30的风口长度L和风口高度H的比值的设定,综合考虑了常见草坪落叶的尺寸和单位时间内进入树叶清理装置200进风口的树叶的数量,以保证树叶可以顺利从树叶清理装置200的进风口30进入机器内部而不会产生堵塞。树叶清理装置200放置在地面上进行使用时,树叶清理装置200的进风口30下端部与地面的距离值小于2CM,这样的数值设定避免进风口30距离地面太远而影响进风口30的吸力,从而很好的保证了树叶清理装置200的吸叶效果。
吸入树叶清理装置200的进风口30的树叶沿着第一延伸部16向树叶清理装置200的蜗壳14移动,并在第一延伸部16与蜗壳14连通端进入蜗壳14内部,为了保证树叶从进风口30进入第一延伸部16后能顺利随气流进入蜗壳14内部,第一延伸部16与蜗壳14连通的一端的连通面积S2的范围为大于95平方厘米。这样设计综合考虑了单位时间内第一延伸部16与蜗壳14连通的一端树叶的通过量,保证了树叶可以很顺畅的沿第一延伸部16进入蜗壳14的内部,而不至于在第一延伸部16与蜗壳14的连通部发生堵塞,从而提高树叶通过的效率。
从树叶清理装置200的进风口30进入树叶清理装置200内部的树叶沿着第一延伸部16向蜗壳14移动,之前已经定义了第一延伸部16和蜗壳14连通一端的连通面积S2的范围,以保证吸入的树叶可以顺利进入蜗壳14内部。同样为提高树叶从进风口30沿第一延伸部16向蜗壳14移动的效率,第一延伸部16具有连接蜗壳14中心的第一端和连接进风口30的第二端,第一延伸部16在第一端的截面积小于在第二端的截面积。并且第一延伸部16从第一端至所述第二端的截面积逐渐变大。优选地,第一延伸部16整体大致具有梯形形状,第一端位于梯形形状的短顶部,而第二端位于梯形形状的长底部。也就是说,第一延伸部16的进风口30端部和与蜗壳14连通端两端之间任一截面的截面积不小于第一延伸部16与蜗壳14连通的一端的连通面积S2。这样保证了树叶沿第一延伸部16行进时候的一个最小的截面积,改善了树叶沿第一延伸部16行进 的环境,提高了树叶被吸入并进入蜗壳14内部的效率。
树叶清理装置200的壳体10上还设置有沿竖直方向上延伸的手柄(图中未示出),手柄的设置是为了方便用户使用完树叶清理装置200需要进行储藏或者清理树叶的作业中需要移动树叶清理装置200的位置时,用户可以通过手柄握持树叶清理装置200进行移动,从而方便了用户的操作。
本发明中树叶清理装置200包括吸取树叶的进风口30和将经碎叶装置粉碎后的树叶排出树叶清理装置200外的出风口60。进风口30的延伸方向和出风口60的延伸方向平行,并且进风口30位于出风口60的下方。进风口30和出风口60分别位于树叶清理装置200的壳体10相对的两侧。这样的设计有助于提高树叶进入树叶清理装置200的壳体10内部之后经过粉碎并从出风口60排出的效率,使得整体上树叶从进风口30进入并从出风口60排出更加的流畅。
本实施例中电机40的输出轴42的方向垂直于地面,碎叶装置的旋转轴线也垂直于地面,这样的电机40的位置和碎叶装置的位置的设计并不是对本发明电机40及碎叶装置具体布置位置的严格限定,本领域技术人员可以想象的是电机40、碎叶装置还可以有其他的布置位置,简单的位置的变换并不会变离本发明保护的精髓,因此都在本发明的保护范围之内。
请参见图14,图14所示出的实施例中,电机40的输出轴42与碎叶装置的旋转轴线重合,并且输出轴42和碎叶装置50的旋转轴线与地面呈一定的角度设置。本实施例中,树叶清理装置200的出风口60的延伸方向与树叶清理装置200的进风口30的延伸方向平行,并且出风口60位于进风口30的上方,树叶经过进风口30进入树叶清理装置200的内部,经过倾斜设置的碎叶装置50粉碎之后,并从出风口60排除,出风口60位置的设置考虑到了碎叶装置50的倾斜设置的位置,在碎叶装置50旋转产生的气流的排出方向设置了出风口60,这样的设置可以保证进入树叶清理装置200的进风口30的树叶经粉碎后能够很顺畅的从出风口60排出。
图14中所示的实施例还可以有如下的变化:第一延伸部16的上部分可以移除,从而只保留第一延伸部16的下部分,这时的第一延伸部16形状类似游乐园的滑梯,用户在使用树叶清理装置200进行吸取和粉碎树叶时,可以看见粉碎装置的工作状态,从而用户可以很容易避免触碰到粉碎装置,从而最终保 护了用户的使用安全。
请参见图15,图15所示出的实施例中,电机40的输出轴42的方向和碎叶装置50的旋转轴线的方向重合,并且电机40的输出轴42的方向和碎叶装置的旋转轴线的方向都垂直于地面。本实施例中,树叶清理装置200的进风口30延伸方向和树叶清理装置200的出风口60的延伸方向都与地面平行,并且碎叶装置50的旋转平面位于树叶清理装置200的进风口30的下方。
请参见图16,图16以俯视的视角示出了相应的实施例。电机40的输出轴42的轴线方向和碎叶装置50的旋转轴线的方向重合,并且电机40的输出轴42的轴线方向和碎叶装置50的旋转轴线的方向都和地面平行。进风口30的延伸方向与出风口60的延伸方向相交叉,出风口60向左弯折设置,位于进风口30的左侧方向。树叶从进风口30进入树叶清理装置200的壳体10的内部,经碎叶装置50打碎后从上方的出风口60排出。出风口60向左弯折设置可使得出风口60远离进风口30,从而保证用户站立在进风口30处通过耙子等辅助工具将草坪树叶拨入进风口30时,出风口60排出的碎叶或者灰尘不会接触到用户,用户的操作健康得到保障。
图16中所示的实施例还可以有如下的变化:树叶清理装置200的第一延伸部16还可以整体移除,直接只保留蜗壳14部分,这样用户在使用树叶清理装置200吸取和粉碎地面的树叶时,可以清楚的看到碎叶装置的工作状态,从而用户可以很容易避免触碰到粉碎装置,从而最终保护了用户的使用安全。
本领域技术人员可以想象的是,树叶清理装置200的电机40、碎叶装置、进风口30和出风口60的布置位置的实施方式还有很多,此处不再一一列举,凡是可以实现将树叶从进风口30吸入树叶清理装置200内部,并在树叶清理装置200内部经碎叶装置打碎,并能从出风口60排出的布置形式都在本发明的保护范围之内。
请参见图7、图14、图15和图16,树叶清理装置200的碎叶装置50包括转动盘,转动盘的中心部位与电机40的输出轴42相配节接。转动盘中心与树叶清理装置200的进风口30之间的水平距离L1小于30cm。即碎叶装置50到进风口30的间距小于30cm。在优选的实施例中,该距离小于20cm。移动盘中心与树叶清理装置200的进风口之间的水平距离L1的设定主要考虑了保证吸 力和碎叶装置磨损后续事项两方面的内容。如下将对两方面的内容进行详细描述:
一、水平距离L1小于30cm这样的设计,可以使得碎叶装置与树叶清理装置200的进风口30的距离限定在一定的范围之内。本发明中,碎叶装置旋转产生的风力会引导气流从进风口30进去树叶清理装置200的内部并最终从树叶清理装置200的出风口排出。碎叶装置与进风口30的距离设置得较小时可以有效提高气流进入进风口30的强度,换言之,进风口30处的吸力更强,从而使得树叶清理装置200具有更好的吸叶效果。
二、草坪树叶通过进风口30进入到树叶清理装置200的内部,并经过碎叶装置粉碎后从树叶清理装置200的出风口排出。使用中碎叶装置与大量的树叶碰撞并将树叶打碎,长期使用会导致碎叶装置发生正常的磨损,一旦碎叶装置发生磨损之后便会导致碎叶装置的吸力降低。
作为弥补,本发明中移动盘中心与树叶清理装置200的进风口之间的水平距离L1小于30cm,将吸管设置的较短,此时用户可以用耙子或者其他的一些辅助工具把树叶直接推进蜗壳14里供粉碎装置粉碎,以此来弥补碎叶装置长期使用之后发生磨损导致吸力下降之后所带来的不足。
草坪树叶经树叶清理装置200的进风口30被吸入树叶清理装置200的壳体10的内部,树叶在壳体10的内部经碎叶装置粉碎后并在气流的带动下最终从树叶清理装置200的出风口60排出。为了避免粉碎后的树叶随意排弃在草坪上的影响美化和难以后续清理,一般来讲用户都会在树叶清理装置200的出风口60处接上树叶收集袋110以收集被碎叶装置粉碎后排出的树叶。如图17所示,排出后的树叶经树叶收集袋110收集后,用户可以将集满树叶的树叶收集袋倾倒到垃圾箱或者是专用垃圾回收袋内。
本发明中树叶收集袋110的具体形式有多种,在其中的实施方式中,树叶收集袋110是由透气性的材质制成,比如布、织制品等,树叶收集袋110与树叶清理装置200的出风口60采用快拆的方式进行连接。快拆方式可以实现用户快速安装树叶收集袋110到树叶清理装置200的出风口和快速从树叶清理装置200的出风口60拆除树叶收集袋110,节约时间,方便易用。
快拆的方式有很多,比如通过卡扣形式连接或者通过松紧带,还可以通过 绳子进行绑缚,当然本领域技术人员可以想象的是,实现快拆的方式包括,但不限于以上所列出的几种形式,只要是可以实现快速拆卸的连接方式都不脱离本发明的保护思想,都在本发明的保护范围之内。
树叶收集袋110采用透气性的材质,粉碎后的树叶和气流通过树叶清理装置200的出风口60进入树叶收集袋110后,气流因为树叶收集袋采用透气性的材质制成而排出树叶收集袋110之外,而粉碎后的树叶则留在了树叶收集袋110内部,用户可以将收集在树叶清理装置110内部的树叶倾倒至垃圾箱。
请参见图18至图20,图18至20列出了另一实施例中的树叶收集袋120。图19和图20中箭头示出了经树叶清理装置200的碎叶装置粉碎后的树叶的进出方向。
树叶收集袋120包括一次性的标准垃圾回收袋121,标准垃圾回收袋121可以是纸质的,也可以是塑料材质的。粉碎后的树叶收集在标准垃圾回收袋121中后,用户可以直接将整个标准垃圾回收袋121作为垃圾进行处理而不用将标准垃圾回收袋121内的粉碎后的树叶倾倒至垃圾桶。而传统的布袋等材质的收集,用户需要将收集的树叶倾倒至垃圾箱,工序较为繁杂,而且常常会尘土飞扬,影响环境,也影响用户的健康。
本实施例中树叶收集袋120还包括与一次性的标准垃圾回收袋121配合使用的辅助安装件122。辅助安装件122包括弹性的环状件123及连接在环状件123上的一圈透气性材质制成的围挡124,围挡124一端连接在环状件123上,另一端与树叶清理装置200的出风口60通过快拆的方式进行连接,快拆的方式包括但不限于卡扣形式、绳子绑缚等,上文已经对快拆的形式进行了详细的描述,此处就不再对快拆进一步描述。
使用时先将弹性的环状件123压缩,然后将辅助安装件122放入一次性标准垃圾回收袋121中再松开弹性的环状件123,此时弹性的环状件123恢复原状,恢复原状的同时,弹性的环状件123将一次性标准垃圾回收袋121的袋口撑开。为了提高撑开后弹性的环状件123对一次性标准垃圾回收袋121的形状的固定效果,优选的,在辅助安装件122的围挡124的外圈增加橡胶条125。
当然,在其他的实施例中,也可以在辅助安装件122的围挡124的外圈增加凸起等。橡胶条或凸起等的增加是为了增大辅助安装件122与一次性标准垃 圾回收袋121之间的摩擦力,从而防止辅助安装件122与标准垃圾回收袋121之间脱开,从而最终增加固定一次性标准垃圾回收袋121形状的效果。本领域技术人员可以想象的增大摩擦力的形式有很多种,包括但不限于使用橡胶条或者凸起等,其他可以实现增加摩擦力的方式都属于本发明的发明思想,都在本发明的保护范围之内。
通过弹性环状件123将辅助安装件122一端固定到一次性标准垃圾回收袋121上,另一端通过快拆的方式快速安装到树叶清理装置200的出风口60上。草坪的树叶经过树叶清理装置200的进风口30吸入树叶清理装置200的壳体10的内部,经过碎叶装置打碎后再从树叶清理装置200的出风口60排出到辅助安装件122的围挡124内,并在气流的带动下继续前行,最终进入到一次性标准垃圾回收袋121内部。
因为辅助安装件122的围挡124采用的是透气性的材质,因此气流和粉碎后的树叶进入辅助安装件122后,气流从辅助安装件122的围挡124排出,而粉碎后的树叶则最终进入到了一次性标准垃圾回收袋121的内部。树叶处理作业完成之后,用户将辅助安装件122一端从树叶清理装置200的出风口60拆除,接着用户压缩一次性标准垃圾回收袋121内部的弹性的环状件123,压缩之后将弹性的环状件123从一次性标准垃圾回收袋121内部取出。总的来说,辅助安装件122起到了连接一次性标准垃圾回收袋121和树叶清理装置200的出风口60的作用。
粉碎后的树叶从树叶清理装置200的出风口60排出并进入辅助安装件122内部,辅助安装件122的围挡124采用的是透气性材质,气流通过围挡124排出。气流排出的同时也会带动灰尘从围挡124排出,容易造成灰尘飞扬,影响环境,同时也影响用户的健康。
因此,优选的,在辅助安装件122的围挡124沿周向安装遮挡部126。遮挡部126采用的是非透气性的材质,设置遮挡部126可以使得从围挡124排出的灰尘不会四处飞扬而影响环境和用户的健康,同时也不会影响气流从围挡124排出。当然,本领域技术人员可以想象的是,遮挡部126具体的形式有很多种,凡是可以实现遮挡从围挡124排出的灰尘,以防止出现尘土飞扬的遮挡部126的形式都属于本发明的发明构思,都在本发明的保护范围之内。
请参见图21,图21中示出了树叶收集袋120与树叶清理装置200的出风口60相配接后进行碎叶收集时的状态图,图21中未示出遮挡围挡124的遮挡部126。
图22至图25示出了另一实施例的树叶收集袋201。
如图22和图23所示,树叶收集袋201主要包括了用于收集树叶的收集袋202、分别连接收集袋202和树叶清理装置200的安装组件203。收集袋202为一内部中空且密封性较好的袋子,仅具有一个连通外部的袋口210。袋口210为柔性,袋口面积可以在一定范围内变化。树叶通过该袋口210进入收集袋202的内部。在本优选的实施例中,收集袋202为塑料袋。构成塑料袋的材料可以是PE,PVC,PP等。通常塑料袋的厚度小于0.1mm,在优选的实施例中,塑料袋的厚度为0.025mm左右。塑料袋的成本比较低,而且密封性较好,树叶不会轻易漏出。
安装组件203除了辅助连接收集袋202和树叶清理装置200之外,还具有引导气体流通的功能,因此安装组件203包括透气部206,通过透气部206空气在安装组件203的内外部之间流通。为了增大流通效率,安装组件203的主体为透气部206。
由于收集袋202比较柔韧,受到拉伸后收集袋202的表面容易变形乃至破裂,为了密封连接收集袋202,安装组件203上设有相互配合的内圈与外圈,内圈与外圈的其中之一与收集袋202的袋口210连接,内圈与外圈的其中另一个与所述透气部206连接,内圈和外圈周向相互抵靠从而使安装组件203连接收集袋202的袋口210。在优选的实施例中,内圈为环形弹性件204,环形弹性件204能够产生径向向外的偏压力,从而使得环形弹性件204与外圈配合。在该实施例中,环形弹性件204与透气部206连接。同时安装组件203还包括安装在收集袋202的袋口210的环形箍205。环形箍205由硬质材料构成,其硬度远大于收集袋202的硬度。环形箍205安装在袋口210可以起到支撑袋口210的作用。环形箍205以内的区域供树叶通过袋口210。在优选的实施例中,环形箍205和收集袋202可分离的设置。这样在不使用的时候,收集袋202可以方便的折叠收藏。而当需要使用的时候,环形箍205可以安装在收集袋202上。具体的安装方式如下,如图24和图25所示,把环形箍205放置于袋口210的 位置,收集袋202的袋口边缘220可以翻转以包裹住环形箍205,这样使得环形箍205和袋口210的相对位置固定。
同时环形弹性件204利用产生的偏压力以抵靠接触环形箍205,从而利用环形弹性件204与环形箍205的配合固定地连接安装组件203和收集袋202。环形弹性件204的半径与环形箍205的半径大致相同。用户压缩环形弹性件204使之能够放入环形箍205径向内侧的空间中,然后释放环形弹性件204利用环形弹性件204的弹性回复力使得环形弹性件的径向外外侧与环形箍205的径向内侧形状配合。如此利用环形弹性件204与环形箍205的配合使得多种袋口尺寸的收集袋202都能够与同一个安装组件203连接,提升了适配通用性。
在优选的实施例中,构成透气部206表面的是布料结构,布料结构的表面具有透气孔,能方便空气流通但是可以阻止树叶通过。具体地,布料结构可以是无纺布,网格布等材料。当安装组件203分别连接收集袋202和树叶清理装置200之后,树叶清理装置产生的空气和树叶的混合物通过安装组件203,混合物中的空气部分通过透气部206向外界排出,而树叶部分则被输送至收集袋202中进行收集,这样可以有效地把树叶和空气进行分离,提高了收集效率。
透气部206具有贯通的第一开口261和第二开口262。其中第一开口261与收集袋202连接,第二开口262与树叶清理装置200连接。树叶从第二开口262移动到第一开口261并进入收集袋202,而空气通过第二开口262从透气部206向外排出,并不会通过第一开口261。如图20和图21所示,环形弹性件204安装在第一开口261处。优选地,第一开口261具有翻边,翻边可以包裹住环形弹性件204,使得环形弹性件204不与环形箍205直接接触。第二开口262设置有收紧带263。收紧带263可选择地收紧或者松开,从而方便的调节第二开口262的面积,使得安装组件203可以连接到不同开口大小的树叶清理装置200上。
请参见图26,树叶清理装200的壳体10上还设置有向上延伸的控制杆130,控制杆130上设置有控制开关132,控制开关132与电机40电性连接用于控制电机40的启动和关闭。
本实施例中控制杆130的形状是U型,控制杆130两自由端与壳体10相连,控制开关132设置在U型控制杆的中间的连接端。在其他的实施例中,控 制杆130还可以为单独的一根向上延伸的竖直杆,控制开关132安装在竖直杆的上端。
当然,本领域技术人员可以想象的是,控制杆130的形状远不止上文所提到的竖直杆和U型杆,其他连接壳体10向上延伸的可以安装控制开关132的控制杆都属于本发明的保护思想,都在本发明的保护范围之内。
控制开关132内部设置有复位机构,当控制开关132受力处于按压状态时,控制开关132接通与电机40之间的电连接,电机40启动;当撤销对控制开关132的压力时,控制开关132在复位机构的作用下恢复到初始状态,控制开关132与电机40之间的电连接断开,电机停止运转。这种形式的开关属于本领域技术人员所习知的技术,对于该种形式的控制开关的实现原理和具体构造不再进行详细描述。
树叶清理装置200放置在地面上进行树叶清理作业时,控制杆130上控制开关132距离地面的开关高度H1的范围为70-100cm。控制开关132距离地面的高度的数值的选定主要考虑到了操作的舒适性。控制开关132设置的过高时,用户需要抬高手臂握持控制开关132,因要维持树叶清理装置一直运转,需要用户一直握持按压控制开关132,用户会非常容易疲劳,而且操作非常的不舒适。
而当控制开关132设置的过低时,用户需要弯腰来操作,一直弯腰握持按压控制开关132同样对用户来说会非常容易疲劳,操作非常的不舒适。因此本发明控制开关132距离地面的高度的数值选择综合考虑了人机工程学理念,控制开关132设置在合适的高度,用户既不用抬高手臂进行握持操作,也不用弯腰进行握持操作,从而保证了用户握持按压控制开关132时的操作的舒适性,操作非常便捷。
此外树叶清理装置200向上设置控制杆130,同时在控制杆130上设立控制开关132还可以提高树叶清理装置200操作的安全性能。因为本发明中控制开关132内部设有复位机构,当控制开关132受力处于按压状态时,控制开关132接通与电机40之间的电连接,电机启动;当撤销对控制开关132的压力时,控制开关132在复位机构的作用下恢复到初始状态,控制开关132与电机40之间的电连接断开,电机40停止运转。
用户如果需要使树叶清理装置200一直处于运行的状态,则需要一只手一直握持按压控制开关132,而用户的另一只手则需要操作耙子等辅助工具将树叶清理装置200周围的树叶移动至树叶清理装置200的进风口30附近,从而被树叶清理装置200吸入机器内部进行粉碎。
因用户一只手需要一直按压控制杆130上的控制开关132,而另一只手需要操作耙子移动树叶清理装置200周边的树叶。因此,当树叶清理装置200处于运行的状态时,用户的两只手都不空闲,都有固定的操作需要进行而不会有多余的时间可以去伸手进入树叶清理装置200的进风口30。树叶清理装置200运转时,伸手进入进风口30处会不小心碰到树叶清理装置200中的碎叶装置的刀片,从而对用户的手造成伤害。
出于安全方面的考虑,在树叶清理装置200运行时,应尽量避免双手触及碎叶装置造成伤害的的可能。本发明中,树叶清理装置200运行时用户的两只手都不空闲,都有固定的操作需要进行而不会有多余的时间会去触碰到碎叶装置的刀片而受到伤害。因此设置控制杆130和控制开关132可以很好的满足了安规上的要求,提高了树叶清理装置200的安全性能,更好的保护了用户的安全。
总的来说,树叶清理装置200向上设置控制杆130并在控制杆130上设置控制开关132,一方面可以提高用户操作的舒适性,另一方面可以提高用户操作时的安全性。
请参见图27至图29,本发明中树叶清理装置200可选的包括安全防护装置140。安全防护装置140包括与电机40电性连接的脚踏开关141,脚踏开关141设置在壳体10之外并可用于控制电机40的运转与停止。
本发明中脚踏开关141包括复位机构,当脚踏开关141处于踩下状态时,电机40开始运转;当撤销对脚踏开关141施加压力时,脚踏开关141在复位机构的作用下恢复至初始位置,此时脚踏开关141与电机40断开电性连接,电机40停止运转。
因本发明中脚踏开关141包括复位机构,如果需要使树叶清理装置200一直处于运行状态,则用户需要一只脚一直踩踏在脚踏开关141上面。脚踏开关141设置为与壳体10间隔一定的距离,间隔一定距离设置是为了使用户一只脚 踩踏在脚踏上面时,另一只脚与树叶清理装置200保持一定的距离,从而避免用户的另一只脚会触碰到树叶清理装置200内部碎叶装置的刀片,而受到伤害。
因此,树叶清理装置200运行时用户一只脚一直踩踏在脚踏上,另一只脚与树叶清理装置200内的碎叶装置的刀片保持足够的安全距离,从而提高了用户操作时的安全性,避免用户的脚触碰到碎叶装置的刀片而受到伤害。
图28至图29示出了脚踏开关142控制树叶清理装置200的电机40启动和关闭的另一实施例。脚踏开关142采用气囊143与活塞144配合从而触发电机40的触发件145。当用户的脚踩下气囊143时,气囊143中的空气推动活塞144向前运动,活塞144向前运动从而挤压触发件145,此时树叶清理装置200的电机40启动。而当用户的脚撤销踩踏气囊143时,气囊143充气恢复原状,活塞144被吸取向后运动,从而停止了对触发件145的挤压,此时树叶清理装置200的电机40停止运转。
脚踏开关142同样需要用户的脚要一直踩踏在脚踏上才可以保证树叶清理装置200持续运转。则用户需要一只脚一直踩踏在脚踏开关142上面。脚踏开关142同样设置为与壳体10间隔一定的距离,间隔一定距离设置是为了使用户一只脚踩踏在脚踏上面时,另一只脚与树叶清理装置200保持一定的距离,从而避免用户的另一只脚会触碰到树叶清理装置200内部碎叶装置的刀片,而受到伤害。
因此,树叶清理装置200运行时用户一只脚一直踩踏在脚踏上,另一只脚与树叶清理装置200内的碎叶装置的刀片保持足够的安全距离,从而提高了用户操作时的安全性,避免用户的脚触碰到碎叶装置的刀片而受到伤害
请参见图30,图30所示出的实施例中,安全防护装置140包括设置在树叶清理装置200进风口30处的辊子146。辊子146的数量设置为两个,一个辊子146设置在进风口30的上端并绕一旋转轴顺时针转动;另一个辊子146设置在进风口30的下端并绕另一旋转轴逆时针转动。两个辊子的旋转轴相互平行并且都与地面平行。
本实施例中所给出的图中,两个辊子146靠近出风口60和远离出风口60交错布置。本领域技术人员可以想象的是,在其他的实施例中,两个辊子146可以沿垂直方向布置或者有其他的布置方式。
两个辊子146之间间隔有供树叶进入进风口的间隙。进风口30上端的辊子146绕一旋转轴顺时针转动,设置在进风口30的下端的辊子146绕另一旋转轴逆时针方向转动,上、下两个辊子146都朝向树叶清理装置进风口30的内部转动,这样设计可使得树叶刚接触到进风口30时就被辊子146带动进入到树叶清理装置200的内部,从而提高了树叶清理装置200的进风口30的进叶效率。
两辊子146的轮毂之间的间隔距离D的范围为小于7.5cm。这样的距离设置可以保证用户无法将手伸入树叶清理装置200的进风口30而触碰到树叶清理装置200内部的碎叶装置的刀片,树叶清理装置200运转时用户如果伸手触碰到碎叶装置的刀片的话,会对用户的手造成伤害。因此两辊子146之间的距离限定可以有效的提高用户操作树叶清理装置200时的安全性。
本实施例中树叶清理装置200的壳体10的内部还设置有用于驱动两个辊子146转动的电机(图中未示出)。在其他的实施例中,辊子146上设置有叶片(图中未示出),树叶清理装置200运转时,碎叶装置转动产生气流,气流从树叶清理装置200的进风口30进入树叶清理装置200的内部,并从树叶清理装置200的出风口60排出。气流从进风口30进入树叶清理装置内部200时,气流会带动叶片和辊子146绕旋转轴转动,叶片和辊子146绕旋转轴转动可以将进入树叶清理装置200的进风口30处的树叶快速吸入,从而提高了树叶清理装置200的进风口30的树叶进入的效率。
上文对进风口30处设置辊子146的具体位置、数量及驱动形式的描述只是举例进行说明以使本发明的发明构思更加容易被理解,并不是对辊子146具体位置、数量及驱动形式的具体限制。本领域技术人员可以想象的是,除了之前已经列举出的辊子146的一些具体形式外,还可以有其他的一些形式,凡是与本发明的发明构思基本相同,达到效果也基本相同的形式,都属于本发明的发明思想,也都在本发明的保护范围之内。
请参见图31,图31示出了一种树叶清理系统400。树叶清理系统400包括树叶清理装置200和耙子300,树叶清理装置200与耙子300配合使用进行草坪树叶的清理工作,耙子300用于将地面的树叶拨向树叶清理装置200的进风口30。耙子300上可拆卸的设置有一对控制开关310,控制开关310可用于控制树叶清理装置200的电机40的开启和关闭。
本发明中,耙子300上一对控制开关310设置为需要将一对控制开关310同时按下时才可以建立与树叶清理装置200的电机40之间的电性连接,从而启动电机40。当用户只按下其中一个控制开关310时,电机40仍然处于断开电性连接的状态,电机40不运转。
本发明中耙子300上的一对控制开关310同样设置为包括复位机构,当一对控制开关310同时持续按下时,电机40的电性连接接通,电机40开始运转;当撤销对控制开关310其中任一一个或者同时撤销对两个控制开关310的压力时,控制开关310在复位机构的作用下恢复至初始位置,此时电机40的电性连接被断开,电机40停止运转。
本发明中耙子300上设置有一对控制开关310,控制开关310设置为包括复位机构,用户要使树叶清理装置200处于一直运转的状态时就需要同时并且持续按压控制开关310才可以保证树叶清理装置200运行。因此树叶清理装置200运转进行树叶清理作业时,用户需要双手同时工作,分别按压一个控制开关310,并不会有机会和时间可以去伸手进入树叶清理装置200的进风口30处而碰到碎叶装置的刀片。
树叶清理装置200运转时,如果用户的手碰到碎叶装置的刀片时会受到重大的伤害,因此本发明中耙子300上一对控制开关310的设计可以有效的提高用户操作树叶清理装置200进行树叶清理作业时的安全性。
本发明中耙子300上的一对控制开关310可以通过有线或无线的方式与树叶清理装置200的电机40之间建立电性连接。以有线的方式建立连接时属于本领域技术人员所习知的公知常识,在此就不再详细描述。
如下将对耙子300上的控制开关310与树叶清理装置200的电机40通过无线方式建立电性连接的主要工作原理进行描述。耙子300上设置有无线发射模块,树叶清理装置200上设置有对应的无线接收模块和控制模块,同时按压耙子300上的控制开关310时,无线发射模块会将启动电机40的指令发射给无线接收模块,无线接收模块会将接收的指令传输给控制模块,由控制模块控制启动电机40。
同样的,当用户撤销对一对控制开关310中任一控制开关310的按压力或者同时撤销对一对控制开关310的按压力时,无线发射模块会将关闭电机40 的指令发射给无线接收模块,无线接收模块会将接收的指令传输给控制模块,由控制模块控制关闭电机40。
当然本领域技术人员可以想象的是,利用耙子300通过无线方式控制树叶清理装置200的电机40启动或停止的方式包括但不限于上述的方式,其他可以实现无线控制的方式也都在本发明的保护范围之内。
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本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。
