下面描述根据本发明一些具体实施例的手持吸尘器。
实施例一、
下面参考附图描述根据本发明实施例的手持吸尘器1000。
如图1所示,根据本发明实施例的手持吸尘器1000,可以包括:尘杯组件100、延伸管300以及持握组件等,其中,尘杯组件100可以通过延伸管300吸入环境中的尘气、并将尘气中的灰尘过滤掉、然后将净化后的气流吹回环境中,从而起到吸附环境中灰尘的作用,持握组件安装在尘杯组件100上且用于手持,例如持握组件可以为提手或图1中所示的手柄组件200等,从而用户可以通过手持持握组件来移动尘杯组件100,以对环境中的目标地点(例如沙发顶、天花板)等进行针对性清洁。
如图1所示,尘杯组件100包括:壳体1、机罩2和负压装置3。其中,机罩2设在壳体1内,负压装置3位于机罩2内,也就是说,壳体1罩设在机罩2外,机罩2罩设在负压装置3外,从而负压装置3是容纳在壳体1内的,从而可以有效地提高尘杯组件100的结构紧凑性,使得尘杯组件100小巧轻便,便于手持且外观美观。优选地,壳体1与机罩2可拆卸地相连,从而方便清洗、维修和更换。
这里,需要说明的是,“机罩2设在壳体1内”当作广义理解,即应当理解为:机罩2的除了设在开口111处的局部参照下一段描述以外的其余部分是设在壳体1的内腔之内的,而机罩2的设在开口111处的局部参照下一段描述可以设在壳体1的内腔之内、也可以由开口111伸出到壳体1的内腔之外。
参照图1,壳体1上具有开口111,机罩2的局部具有排气口220且设在开口111处以由开口111显露出,也就是说,机罩2的局部设在开口111处且由开口111显露出,且该局部具有排气口220,排气口220也由开口111显露出,从而机罩2内的气流可以通过排气口220和开口111流通到壳体1之外。
其中,“机罩2的局部设在开口111处”指的是:机罩2的局部封盖开口111,以使开口111仅与该局部上的排气口220连通。其中,该局部的至少部分还可以由开口111伸出到壳体1的内腔之外如图1和图3所示,以更加可靠且有效地排出气流,且可以提高机罩2的该局部与开口111定位准确性,使尘杯组件100的工作可靠性更高。
参照图2,壳体1上具有吸尘口112,机罩2与壳体1之间限定出与吸尘口112连通的除尘腔A1,除尘腔A1可以由机罩2的外表面与壳体1的内表面共同限定出,机罩2内限定出连通在排气口220与除尘腔A1之间的排气腔A3。这样,由于除尘腔A1限定在机罩2与壳体1之间、且排气腔A3限定在机罩2内,从而除尘腔A1围绕排气腔A3。
负压装置3用于向排气腔A3提供负压,以使环境中的尘气通过吸尘口112吸入除尘腔 A1内尘气分离、并使从除尘腔A1内分离出的净化气流进入机罩2、即进入排气腔A3内以由排气口220、开口111排出到壳体1以外的环境中。简言之,环境中的尘气经由尘杯组件100内的风道、如从除尘腔A1到排气腔A3,尘气中的灰尘可以滤储在尘杯组件100中、而净化后的气流可以回流到环境中。
由此,从尘杯组件100内的风道布局来看,由于除尘腔A1围绕排气腔A3,从而极大地提高了风道布局的紧凑性,降低吸力损耗,提高能效。而且,由于排气口220形成在机罩2上且可以通过壳体1上的开口111直接将气流排出到环境中,从而有效地缩短了排气路径,进一步降低了能耗,提高了能效。另外,由于吸尘口112形成在壳体1上且与限定在壳体1与机罩2之间的除尘腔A1连通,且由于排气口220形成在机罩2上且与机罩2内的排气腔A3连通,从而风道的布局简单、加工方便且不会发生气流流动短路的问题,滤尘可靠性高、效果好。
当然,本发明不限于此,在本发明的其他实施例中,排气口220还可以不形成在机罩2上,例如排气口220还可以形成在壳体1上,排气腔A3可以通过连接通道等与排气口220连通,此时,壳体1上可以不具有开口111,机罩2的局部也不必位于开口111处以显露出。
在本发明的一些优选实施例中,机罩2为筒形且设在壳体1内,机罩2的轴向一侧外端面(例如图1中所示的下端面)与壳体1的局部内表面(例如图1中所示的下表面)贴合或穿出壳体1的局部内表面(例如图1中所示的下表面),壳体1的内表面与机罩2的外周面之间限定出沿机罩2的周向环绕机罩2的除尘腔A1。由此,尘杯组件100内的风道布局更加紧凑,吸排气路径更短,能耗更低,能效更高。
优选地,如图1和图3所示,壳体1和机罩2均形成为筒形,且壳体1的轴线和机罩2的轴线平行设置,机罩2的外底壁与壳体1的内底壁贴合或贯穿壳体1的内底壁,此时,除尘腔A1可以为限定在壳体1的内周壁与机罩2的外周壁之间的环柱形空腔,这样,当将吸尘口112沿除尘腔A1的切向开设时,除尘腔A1还可以作为旋风分离腔进行旋风式尘气分离,从而提高净化效果。进一步优选地,壳体1和机罩2同轴布置,即筒形的壳体1的轴线和筒形的机罩2的轴线重合,此时除尘腔A1可以为圆环柱形空腔,尘气分离效果更好,且方便下文所述的除尘装置4的安装。
综上所述,根据本发明实施例的手持吸尘器1000,结构紧凑、小巧轻便、手持省力,且手持吸尘器1000的风道紧凑、能耗小、能效高。
下面参考附图11-图15描述根据本发明一些实施例延伸管300。
具体地,延伸管300适于与尘杯组件100的吸尘口112相连。也就是说,当尘杯组件100需要延伸管300进行吸尘时,可以将延伸管300装配到吸尘口112上,而当尘杯组件100不需要延伸管300进行吸尘时,例如需要其他配件、例如缝隙吸头、除螨吸头等进行吸尘时,可以将延伸管300从吸尘口112上拆卸下来,并将实际需要的配件装配到吸尘口112上。
例如在本发明的一些具体示例中,参照图14,延伸管300的一端与吸尘口112可拆卸地直接相连,例如延伸管300可以通过卡扣快拆结构安装到吸尘口112上、并从吸尘口112上拆卸下来。由此,方便拆装。
例如在本发明的另一些具体示例中,参照图15,延伸管300的一端与吸尘口112通过伸缩软管400可拆卸地间接相连。例如延伸管300可以通过快拆结构安装到伸缩软管400上、并从伸缩软管400上拆卸下来,伸缩软管400可以通过快拆结构安装到吸尘口112上、并从吸尘口112上拆卸下来。由此,延伸管300可以通过伸缩软管400的伸缩调节来实现放长和收短,方便拆装,且方便连接,且可以提高手持吸尘器1000的吸尘范围。这里,需要说明的是,伸缩软管400的概念为本领域技术人员所熟知,这里不再赘述。
例如在本发明的再一些具体示例中,参照图15,延伸管300的一端与吸尘口112通过伸缩软管400连通。例如,伸缩软管400的一端可以伸入且固定在延伸管300内、另一端 与吸尘口112可拆卸地相连。由此,装配时,可以将伸缩软管400伸入延伸管300的内孔中且将伸缩软管400的端部固定在延伸管300内部。优选地,尘杯组件100上具有第一连接结构,延伸管300上的一端上具有第二连接结构,第二连接结构与第一连接结构可拆装地配合,由此,当将第一连接结构和第二连接结构装配在一起时,延伸管300的一端可以固定在尘杯组件100上,当用户将第一连接结构和第二连接结构的装配关系拆卸开时,延伸管300可以从尘杯组件100上取下。例如第一连接结构可以为卡钩件、第二连接结构可以为卡块等。
由此,当需要使用延伸管300进行清洁时,可以将伸缩软管400的另一端连接到尘杯组件100上的吸尘口112上,从而手持吸尘器1000在使用的过程中,当不需要过长的延伸管300时,延伸管300的一端可以连接在杯身11上、例如通过卡扣快拆结构连接在杯身11上,此时,伸缩软管400可以完全容纳在延伸管300内,而当需要较长的延伸管300时,延伸管300可以从杯身11上分离出,此时,伸缩软管400的另一端可以从延伸管300中抽出并显露出来,实现延长效果。
在本发明的一些实施例中,如图11所示,延伸管300包括:管体件61和转动件62,管体件61为两端敞开的空心管且管体件61的一端适于与吸尘口112相连,转动件62设在管体件61的另一端上且与管体件61可转动地相连,也就是说,转动件62绕管体件61的另一端的端头可自由转动,转动件62上具有与管体件61内部连通的吸入孔622,环境中的灰尘可以通过吸入孔622进入管体件61,并沿着管体件61进入吸尘口112。由此,当转动件62相对管体件61转动时,吸入孔622的朝向相对管体件61可以发生改变。这样,当管体件61的倾斜角度不变时,可以通过转动转动件62的方式,使转动件62上的吸入孔622的入口(即朝向)对准清洁地点,从而使得延伸管300可以对不同位置处的地点进行有效地清洁,提高延伸管300的吸尘角度范围。
由此,当用户采用延伸管300进行吸尘时,当需要对不同的位置进行吸尘清洁时,无需采用抬高、降低、或者倾置尘杯组件100的方式来调整延伸管300整体的倾斜角度,仅需枢转管体件61上的转动件62来调整转动件62的入口朝向,从而可以针对不同的位置地点进行清洁,以取得良好的吸尘效果,进而降低了用户的劳动强度,使得吸尘器1000更加方便使用。
例如在本发明的一个具体使用示例中,参照图12和图13,当采用延伸管300进行清洁时,可以旋转转动件62,例如沿图13中由A1到A2方向转动转动件62,使吸入孔622旋转至与待清洁表面相垂直的位置(如图13所示状态),从而提高清洁效果。而不需要延伸管300进行清洁时,可以旋转转动件62,例如沿图13中由A2到A1方向转动转动件62,使吸入孔622旋转至与管体件61中心轴线相平行的位置(如图12所示状态),从而方便收纳。
具体地,转动件62与管体件61为一体件,也就是说,延伸管300无论是处于使用状态、还是处于非使用的状态,转动件62与管体件61均是连接在一起的,用户无法轻松自如地将转动件62从管体件61上随意取下、以更换其他配件。或者说,管体件61的另一端上不具有与其他配件装配的结构,从而即使是将转动件62从管体件61的另一端上强行拆卸下来,管体件61的另一端也不能与其他配件进行装配。由此,有效地避免了用户自行拆装转动件62而引起的转动件62工作灵活性降低的问题。这里,需要说明的是,当延伸管300需要维修时,专业人员可以强行将转动件62与管体件61拆开,此种技术方案也应当理解为转动件62与管体件61为一体件。
这里,需要说明的是,相关技术中的一些手持吸尘器具有延伸管,用户可以根据实际需要在延伸管上安装多种配件,然而,在用户多次进行拆卸安装配件时,配件难以再与延伸管牢靠相连,很容易出现连接松动不牢靠的现象,降低使用可靠性和使用寿命。而在本文中,将转动件62与管体件61加工成不可随意拆分的一体件结构,从而可靠且有效地解 决了上述技术问题。
综上所述,根据本发明实施例的用于手持吸尘器1000的延伸管300,由于管体件61的远离吸尘口112的一端具有可转动的转动件62,从而可以通过枢转转动件62的方式来调整延伸管300的吸气朝向,从而提高延伸管300的吸气角度范围,而且,由于管体件61与转动件62不可拆卸,从而有效地提高了延伸管300整体的工作可靠性、灵活性和使用寿命。
在本发明的实施例中,转动件62与管体件61可以通过多种方式可枢转地相连。例如在下述示例一中,管体件61与转动件62可以通过枢转轴64相连。例如在下述示例二中,管体件61与转动件62可以通过球面配合连接。由此,枢转可靠、灵活性高,且容易实现。
示例一、
参照图12和图13,转动件62包括半环部621,也就是说,转动件62大体形成为半圆筒形,半环部621限定出沿其轴线方向延伸的吸入孔622,半环部621罩设在管体件61的另一端外,且半环部621周向上的两端通过枢转轴64与管体件61相连。由此,管体件61不会对转动件62的转动造成干扰,确保转动件62可以自由灵活枢转。
示例二、
图未示出该示例,管体件61的另一端的外表面形成为外球面,转动件62的内表面形成为内球面,例如转动件62可以形成为球形壳体且吸入孔622可以沿转动件62的径向贯通转动件62,转动件62套在管体件61的另一端外以使内球面与外球面配合连接。由此,管体件61不会对转动件62的转动造成干扰,确保转动件62可以自由灵活枢转。
优选地,管体件61与转动件62之间设有阻尼件。例如在上述示例一中,半环部621与枢转轴64之间设有阻尼件。例如在上述示例二中,内球面与外球面之间设有阻尼件。由此,当用户枢转转动件62后,转动件62可以可靠地停止在该角度不再自动枢转,从而使得延伸管300可以稳定且可靠地朝向用户调整过方向进行吸尘,进一步提高吸尘效果。这里,需要说明的是,阻尼件为用于增大摩擦力的介质,其具体产品应为本领域技术人员所熟知,这里不再详述。
在本发明的一些实施例中,转动件62上可以具有清洁件63、例如抹布、海绵或者下文所述的毛刷部等,由此延伸管300在进行吸尘的过程中可以同时通过清洁件63进行清洁,从而达到更好的清洁效果。其中,清洁件63可以是固定在转动件62上的,即为不可拆卸、不可更换的,清洁件63还可以是可拆卸地固定在转动件62上的,即为可以更换和可以拆卸的。由此,当延伸管300的一端具有清洁件63时,可以更加方便用户进行清洁,提高清洁效率。
例如在本发明的具体示例中,转动件62上具有位于吸入孔622边沿上的刷毛部631。参照图12和图13,刷毛部631可以连接在半环部621的轴向上的一端且沿半环部621的周向延伸,也就是说,半环部621的一侧轴向端面上具有沿半环部621轴向延伸出的多个刷毛,且多个刷毛在半环部621的周向上均匀地间隔开。由此,刷毛部631的设置方式简单、便于实现,且由于刷毛部631环设在吸入孔622外,从而不会干扰吸入孔622吸入灰尘。
在本发明的一些扩展实施例中,延伸管300可以为两端敞开的空心管,延伸管300的一端与吸尘口112可拆卸地相连、另一端上具有与延伸管300为一体件的清洁件63。这样,由于延伸管300的一端具有清洁件63,从而在将延伸管300从尘杯组件100上拆卸下来时,用户还可以单独使用具有清洁件63的延伸管300进行清扫工作,从而使得清洁件63具有独立于尘杯组件100的独立功能。
例如在其中一些具体示例中,延伸管300包括管体件61和清洁件63,清洁件63直接安装在管体件61的另一端上,且清洁件63与管体件61为一体件。也就是说,延伸管300无论是处于使用状态、还是处于非使用的状态,清洁件63、管体件61均是连接在一起的, 用户无法轻松自如地将清洁件63从管体件61上随意取下、以更换其他配件。由此,有效地避免了由于清洁件63可经常拆卸更换而引起的使用寿命低的问题。这里,需要说明的是,当延伸管300需要维修时,专业人员可以强行将清洁件63与管体件61拆开,此种技术方案也应当理解为清洁件63与管体件61为一体件。
例如在其中另一些具体示例中,延伸管300包括管体件61、转动件62和清洁件63,清洁件63直接安装在转动件62上、以间接安装在管体件61的另一端上,此时清洁件63、转动件62、管体件61为一体件。也就是说,延伸管300无论是处于使用状态、还是处于非使用的状态,清洁件63、转动件62与管体件61均是连接在一起的,用户无法轻松自如地将转动件62从管体件61上随意取下、也无法轻松自如地将清洁件63从转动件62上取下、以更换其他配件。由此,有效地避免了由于清洁件63和转动件62可经常拆卸更换而引起的使用寿命低的问题。这里,需要说明的是,当延伸管300需要维修时,专业人员可以强行将清洁件63、转动件62与管体件61拆开,此种技术方案也应当理解为清洁件63、转动件62、管体件61为一体件。
在本发明的一些实施例中,延伸管300为伸缩管。由此,延伸管300可以根据实际需要进行伸长和缩短调节,以根据待清洁位置的远近对延伸管300的长短进行适应性调节,从而方便用户使用。这里,需要说明的是,可以进行伸长缩短的管件的具体实施方式应为本领域技术人员所熟知,例如,雨伞炳、晾衣撑杆等都为伸缩管,这里不再赘述。
综上,根据上述扩展实施例的延伸管300,当延伸管300为伸缩管、或通过伸缩软管400与尘杯组件100相连时可以实现自由伸缩、长短调节,从而更加方便用户使用,而且,当延伸管300通过伸缩软管400与尘杯组件100相连时,即使延伸管300与尘杯组件100分离也能够通过伸缩软管400的过渡连接作用实现吸尘。另外,由于延伸管300的一端具有清洁件63,从而当延伸管300与尘杯组件100上完全拆卸下来时也能够单独使用,例如作为扫把等使用,从而提高延伸管300的多功能性。
下面参考图1-图10描述根据本发明一些实施例尘杯组件100。
如图1和图2所示,壳体1内可以具有连通腔A2,连通腔A2连通在除尘腔A1与排气腔A3之间,从而从除尘腔A1内分离出的气流可以通过连通腔A2进入机罩2内、即进入排气腔A3内。由此,通过在壳体1内加工连通腔A2以将除尘腔A1和排气腔A3连通起来,从而尘杯组件100内的风道布局更加紧凑,吸气能耗更低,能效更高。当然,本发明不限于此,还可通过其他方式将除尘腔A1与排气腔A3连通在一起,例如,可以通过设置连接管路等将除尘腔A1与排气腔A3连通起来。
参照图1,壳体1包括:杯身11和机盖12,其中,杯身11的一端敞开,机盖12封盖在杯身11的敞开端上,由此,壳体1的结构简单,便于加工和装配。优选地,机盖12可拆卸地封盖在杯身11的敞开端上。也就是说,机盖12与杯身11可拆卸地相连,从而方便将机盖12从杯身11上拆卸下来,以便于清洗杯身11和机盖12。例如,杯身11与机盖12可以通过螺纹结构或卡扣结构等可拆卸地相连。
另外,在本发明的一些实施例中,杯身11还可以包括主体部和底盖部,主体部为两端敞开的筒形,底盖部可开合地连接在主体部的一个敞开端上,由此,当将底盖部打开时,可以将主体部内积聚的灰尘到出,由此,方便使用。
参照图2,吸尘口112和开口111可以均形成在杯身11上,连通腔A2可以限定在机盖12内,也就是说,杯身11上具有开口111和吸尘口112,机盖12内具有连通腔A2,从而方便连通腔A2的加工,且当连通腔A2限定在机盖12内时,连通腔A2可以位于机罩2和除尘腔1的同侧(例如图1中所示的上侧),从而进一步简化了风道的布局,提高了工作可靠性。例如在本发明的一个优选示例中,杯身11形成为立筒形,即立式设置的筒形,杯身11的顶端敞开以构造成敞开端,机盖12封盖在杯身11的顶端,吸尘口112可以形成在杯身11的侧壁上,开口111可以形成在杯身11的底壁上。由此,壳体1的整体构造简单、 便于加工、拆卸和装配。
这里,需要说明的是,“筒形”当作广义理解,即筒形的横截面不限于此圆形,且筒形的各横截面的尺寸可以相等或不等。另外,“立式设置”指的是筒形的轴线大体沿图1中所示的上下方向延伸,但是,手持吸尘器1000在使用的过程中,根据用户的手持角度变化,杯身11可以不再保持立式状态,例如,杯身11可以处于倾斜状态或者卧式状态等。
进一步地,机罩2设在杯身11内,除尘腔A1限定在机盖12、杯身11以及机罩2之间,而连通腔A2限定在机盖12内。由此,除尘腔A1可以很自然地、且容易地与连通腔A2连通在一起,而且,除尘腔A1与连通腔A2的位置布局条理清晰,从而使得尘杯组件100的风道畅通性高,不会发生流动短路的问题。
如图1和图2所示,机盖12包括:内盖121和外盖122,内盖121和外盖122均罩设在杯身11的敞开端上且外盖122罩设在内盖121外,连通腔A2限定在外盖122与内盖121之间,除尘腔A1限定在机罩2、内盖121和杯身11之间,内盖121上具有连通在连通腔A2与除尘腔A1之间的入流连通孔12110,也就是说,除尘腔A1通过内盖121上的入流连通孔12110连通至连通腔A2,从而,除尘腔A1内分离出的气流可以通过入流连通孔12110进入连通腔A2内。由此,机盖12的结构简单,便于加工连通腔A2。
优选地,内盖121上具有向杯身11内部延伸的延伸段1211,入流连通孔12110由延伸段1211限定出,例如在图1所示的示例中,内盖121可以水平设置在杯身11的顶部,延伸段1211可以由内盖121向下延伸至杯身11内。由此,入流连通孔12110的连通效果更好,除尘腔A1内分离出的气流可以更加稳定、可靠地通过延伸段1211进入到连通腔A2内。
优选地,内盖121上进一步具有向杯身11内部延伸的出风圈1212,出风圈1212套接在机罩2的敞开端内或外,出风圈1212限定出连通在连通腔A2与机罩2内部、即连通在连通腔A2与排气腔A3之间的出流连通孔12120,例如在图1和图2所示的示例中,内盖121可以水平设置在杯身11的顶部,出风圈1212可以由内盖121向下延伸至杯身11内且与机罩2的进风端(例如图1中所示的机罩2的顶端)敞开端套接配合。由此,出流连通孔12120的出风效果更好,连通腔A2内分离出的气流可以更加稳定、可靠地通过出风圈1212进入到排气腔A3内,避免气流流通短路的问题。
在本发明的一个可选示例中,内盖121和外盖122分别可拆卸地安装在杯身11上。也就是说,内盖121与杯身11可拆卸地直接相连,外盖122与杯身11可拆卸地直接相连,而内盖121与外盖122没有直接相连,由此,可以直接从杯身11上拆卸下来外盖122和内盖121,从而可以方便地清洗内盖121和外盖122。
例如在图1所示的示例中,内盖121的部分嵌入杯身11内且边沿止抵在杯身11的敞开端上,以防止内盖121落入杯身11内部,外盖122与杯身11的敞开端的外壁卡扣连接或螺纹连接。由此,可以简单地将外盖122从杯身11上拆卸下来,然后从杯身11上取下内盖121即可完成拆卸。由此,结构简单、便于拆卸和清洗。
在本发明的另一个可选示例中,图未示出该示例,内盖121可拆卸地安装在外盖122上、且内盖121与外盖122中的其中一个可拆卸地安装在杯身11上。也就是说,外盖122与内盖121可拆卸地直接相连,且内盖121和外盖122中的其中一个与杯身11可拆卸地直接相连,由此,可以直接从杯身11上拆卸下来机盖12,再将内盖121和外盖122拆开,从而可以方便地清洗内盖121和外盖122。
参照图1和图2,机盖12还包括:盖内过滤件1221,盖内过滤件1221可拆卸地设在内盖121与外盖122之间且位于连通腔A2内,由此,气流从除尘腔A1进入连通腔A2后,可以经过盖内过滤件1221的进一步过滤,以提高除尘效果,使更加洁净的空气进入排气腔A3内,确保负压装置3可以更加可靠地工作,使用寿命更长。
优选地,盖内过滤件1221可拆卸地设在连通腔A2内。也就是说,盖内过滤件1221 是可以从连通腔A2内拆除的,从而便于清洗或者更换盖内过滤件1221,从而提高吸尘过滤效果。例如在图1所示的示例中,盖内过滤件1221可以夹设定位在下文所述的盖内风道件1222与内盖121之间,又例如在图3所示的示例中,盖内过滤件1221可以夹设定位在内盖121与外盖122之间。由此,当将内盖121与外盖122拆开之后,盖内过滤件1221可以直接脱出,从而进一步提高了拆卸效率。
参照图1-图4,机盖12还包括盖内风道件1222,盖内风道件1222与内盖121共同限定出连通腔A2。由此,方便连通腔A2的形成。例如在图3所示的示例中,盖内风道件1222一体形成在外盖122的内壁面上,也就是说,外盖122的内壁面可以构造成盖内风道件1222,从而方便加工。又例如在图1所示的示例中,盖内风道件1222可拆卸地设在内盖121与外盖122之间,从而方便盖内风道件1222的拆卸和清洗。
优选地,参照图3和图4,连通腔A2包括多个独立的连通风道A20。也就是说,盖内风道件1222上可以形成有多个连通槽,每个连通槽与内盖121之间限定出一个连通风道A20,多个连通风道A20构造成连通腔A2。入流连通孔12110为多个且与多个连通风道A20对应连通,也就是说,每个入流连通孔12110分别对应一个连通风道A20,从而多个入流连通孔12110可以一一对应地向多个连通风道A20内输入气流。由此,过滤效果更好。
优选地,如图1和图2所示,盖内过滤件1221为多个且对应地设在多个连通风道A20内,也就是说,进入每个连通风道A20内的气流均可以被一个盖内过滤件1221过滤。由此,可以有效地提高过滤效果。当然,本发明不限于此,盖内过滤件1221还可以为一个且为环形,此时,每个连通风道A20内可以分别设有盖内过滤件1221的部分,由此,同样可以提高过滤效果,且便于拆装。
在本发明的一些实施例中,位于机罩2内的负压装置3可以安装在机罩2上,由此,方便负压装置3的安装,且整体结构简单。当然,本发明不限于此,负压装置3还可以安装在壳体1上等。
例如在图1所示的示例中,负压装置3通过托架26安装在机罩2上,例如,托架26可以包括:托起部261和连接部262,托起部261支撑在负压装置3的底部,连接部262与托起部261相连、且连接至机罩2。由此,托架26的结构简单,可以将稳定且可靠地将负压装置3固定在机罩2内。
优选地,连接部262与机罩2可拆卸地相连。由此,可以通过将托架26从机罩2内拆下的方式从机罩2中取出负压装置3,从而方便负压装置3的维修和更换。例如在本发明的一些优选示例中,连接部262和机罩2均形成为筒形,连接部262的外周壁与机罩2的内周壁通过卡扣结构或螺纹结构可拆卸地相连,由此,方便加工且拆装效果更好。这里,需要说明的是,在本文的描述中,螺纹连接和卡扣连接的技术方案均为本领域技术人员所熟知,这里不再详述。
进一步地,参照图1,托架26进一步还可以包括:限位部263,限位部263为环形且圈套负压装置3、且连接至连接部262和/或托起部261。也就是说,限位部263一方面与负压装置3限位配合,另一方面可以连接至连接部262、也可以连接至托起部261、还可以同时连接至连接部262和托起部261,例如在图1所示的示例中,限位部263可以与托起部261为一体件。由此,托架26可以更加稳定且可靠地将机罩2固定在壳体1内。
参照图1,托架26与负压装置3之间设有减振件264。由此,在负压装置3工作的过程中即便产生振动,振动也会被减振件264削弱,而不会完全传递给托架26,从而有效地提高了托架26与机罩2的连接可靠性,而且,通过设置减振件264,还可以有效地降低振动噪声,提高手持吸尘器1000的使用舒适性。
优选地,减振件264的面向负压装置3的一侧表面的局部与负压装置3间隔开。例如在图1所示的示例中,减振件264上具有凸起2641,负压装置3支撑在凸起2641上,从而减振件264的不具有凸起2641的表面与负压装置3之间可以保持一定间隙,从而进一步 提高了减振件264的减振效果。
如图1所示,机罩2内进一步具有防止负压装置3上窜的定位件23,由此,负压装置3一方面可以受到托架26施加给其的防下降托力、另一方面可以受到定位件23施加给其的防上窜抵力,从而负压装置3可以更加稳定可靠地设在机罩2内,以提高负压装置3的工作可靠性。
优选地,定位件23为筒形,且定位件23的轴向一端(例如图1中所示的上端)可以与机罩2的进气端连通,定位件23的轴向另一端(例如图1中所示的下端)可以与负压装置3的进气端连通,从而定位件23另一方面还可以起到对气流的导向作用,使得进入机罩2内的气流可以更好地被负压装置3吹走,以降低吸排气阻力,降低能耗,提高能效。优选地,定位件23的轴向另一端(例如图1中所示的下端)与负压装置3的连接处设有密封件24,从而进一步提高负压装置3的吸气能力,降低能耗。
参照图1和图2,开口111可以形成在壳体1的底壁上。此时,机罩2的底部设在开口111处且排气口220形成在机罩2的底部上,例如形成在机罩2的底壁上,也就是说,壳体1的底壁上具有开口111,机罩2的底部具有排气口220且设在开口111处以由开口111显露出。由此,机罩2内的气流可以自上向下通过排气口220和开口111排出,也就是说,经手持吸尘器1000净化的气流是向下排出的,而非向上或向侧面吹出,从而有效地改善了吹出的气流吹向用户、给用户造成的不舒适体验,进而提高了手持吸尘器1000的使用舒适性。
优选地,排气口220为多个且均匀地设在机罩2的底壁上。由此,手持吸尘器1000可以更加有效、迅速、且畅通地排出净化气体,从而降低吸排气阻力,进一步降低能耗,提高手持吸尘器1000的整体能效。
参照图1和图2,当机罩2形成为立筒形时,机罩2可以包括:罩身21和罩底22,罩身21形成为立筒形,罩底22形成为碗形且连接在罩身21的底部,排气口220形成在罩底22上。由此,机罩2的结构简单、便于拆装且便于加工。另外,由于机罩2便于拆装,从而一方面便于用户清洁机罩2内部,另一方面便于专业人员维修和更换负压装置3。
当然,本发明不限于此,当机罩2仅形成为筒形但非立式设置时,机罩2还可以包括:罩身21和罩底22,但是罩身21仅形成为筒形且非立式设置,罩底22形成为碗形且连接在罩身21的轴向一端。下面,仅以机罩2形成为立筒形为例进行说明,当本领域技术人员阅读了下面的技术方案后,显然可以理解当机罩2仅形成为筒形但非立式设置的技术方案。
优选地,罩身21位于壳体1内且罩身21的底端止抵在壳体1的内底壁110上,此时,除尘腔A1仅沿罩身21的周向环绕罩身21、而并不包围罩底22,从而进一步提高了尘杯组件100的风道布局的紧凑性,以降低吸排气能耗、提高能效,同时确保尘杯组件100的结构更加小巧轻便。另外,罩身21与壳体1通过此种方式定位,还可以有效地提高机罩2与壳体1的定位可靠性,且方便拆装。
例如在本发明的一个优选示例中,图未示出该示例,罩身21和罩底22均位于壳体1内且罩底22的外底壁与壳体1的内底壁110贴合,且罩底22的具有排气口220的位置与开口111正对。由此,安装方便。
例如在本发明的另一个优选示例中,参照图1和图3,罩身21位于壳体1内,罩底22的上部伸入壳体1内与罩身21配合,罩底22的下部由开口111向下穿出壳体1的内底壁110,且罩底22上的排气口220也由开口111向下穿出壳体1的内底壁110,此时,机罩2的底部由开口111向下穿出壳体1的内底壁110。由此,安装方便且定位效果好。优选地,罩底22的外周壁与罩身21的内周壁卡扣连接或螺纹连接。由此,方便罩身21与罩底22的拆装。
进一步地,参照图1,尘杯组件100进一步包括:罩内过滤件25,罩内过滤件25设在机罩2内且位于排气口220与负压装置3之间。也就是说,排气腔A3内的气流需要经过 罩内过滤件25的过滤之后,再通过排气口220排出。由此,可以进一步提高手持吸尘器1000排出气体的净化效果。
在本发明的一些实施例中,参照图3,尘杯组件100进一步包括:除尘装置4,除尘装置4设在除尘腔A1内且在除尘腔A1内限定出旋风分离腔。由此,进入除尘腔A1内的尘气可以在旋风分离腔内以旋风的方式将灰尘离心甩出,从而进一步提高除尘效果。
优选地,在气流的流动方向上,旋风分离腔包括多级依次连通的旋风腔,由此,进入除尘腔A1内的尘气可以依次经过多级旋风腔多次尘气分离,从而提高除尘效果。下面仅以旋风分离腔为二级和三级为例进行说明,在本领域技术人员阅读了下面的技术方案后,显然可以推知旋风腔为更多级的技术方案,这里不再赘述。
例如在图4所示的示例中,当旋风分离腔为二级时,旋风分离腔包括一级旋风腔A11和二级旋风腔A12,一级旋风腔A11接通在二级旋风腔A12的上游,由此,进入除尘腔A1内的尘气先进入一级旋风腔A11内尘气分离,再进入二级旋风腔A12内尘气分离。又例如,当旋风分离腔为三级时,图未示出该示例,旋风分离腔包括一级旋风腔、二级旋风腔和三级旋风腔,一级旋风腔接通在二级旋风腔的上游,二级旋风腔接通在三级旋风腔的上游,由此,进入除尘腔A1内的尘气先进入一级旋风腔内尘气分离,再进入二级旋风腔内尘气分离、再进入三级旋风腔内尘气分离。
优选地,机罩2为筒形,每级旋风腔均形成为环柱形空腔,且在气流的流动方向上,上游一级旋风腔沿机罩2的周向环绕下游一级旋风腔,例如一级旋风腔沿机罩2的周向环绕二级旋风腔、二级旋风腔沿机罩2的周向环绕三级旋风腔,依此类推。进一步优选地,最下游一级旋风腔沿机罩2的周向环绕机罩2,例如当旋风腔为二级时,二级旋风腔A12沿机罩2的周向环绕机罩2,当旋风腔为三级时,三级旋风腔沿机罩的周向环绕机罩2,依此类推。由此,可以提高旋风腔整体的布局紧凑性,降低吸气装置3的吸气能耗。
下面,简要描述根据本发明一些实施例的除尘装置4。
如图1和图2所示,除尘装置4使旋风分离腔为二级,此时,除尘装置4包括第一旋风分离件41和第二旋风分离件42,其中,第一旋风分离件41限定出二级旋风腔A12,从而又可以称为二级旋风分离件,第二旋风分离件42限定出一级旋风腔A11,从而又可以称为一级旋风分离件。
当然,本发明不限于此,除尘装置4还可以仅包括第一旋风分离件41或第二旋风分离件42,此时,除尘装置4使旋风分离腔为一级。下面,仅以除尘装置4既包括第一旋风分离件41又包括第二旋风分离件42为例进行说明,本领域技术人员在阅读了下面的技术方案后,显然可以理解除尘装置4仅包括第一旋风分离件41或第二旋风分离件42的技术方案。
参照图3和图4,当机罩2为筒形时,第一旋风分离件41设在除尘腔A1内且沿机罩2的周向环绕机罩2,负压装置3使尘气进入除尘腔A1内通过第一旋风分离件41尘气分离。由此,当第一旋风分离件41沿机罩2的周向环绕机罩2时,第一旋风分离件41可以更加充分地利用除尘腔A1内的空间,从而提高尘气分离效果。另外,尘杯组件100的结构更加紧凑,小巧轻便。
参照图3和图4,当机罩2为筒形时,第二旋风分离件42为筒形,第二旋风分离件42套设在机罩2与壳体1之间,例如第二旋风分离件42可以同轴地套设在机罩2外,负压装置3使尘气进入除尘腔A1内通过第二旋风分离件42尘气分离。由此,当第二旋风分离件42沿机罩2的周向环绕机罩2时,第二旋风分离件42可以更加充分地利用除尘腔A1内的空间,从而提高尘气分离效果。另外,尘杯组件100的结构更加紧凑,小巧轻便。在本实施例中,当尘杯组件100还包括第一旋风分离件41时,第一旋风分离件41可以位于第二旋风分离件42与机罩2之间,也就是说,第二旋风分离件42可以位于第一旋风分离件41与壳体1之间,此时,进入除尘腔A1内尘气可以先通过第二旋风分离件42进行尘气分离、 再通过第一旋风分离件41进行尘气分离。
在本发明的一些实施例中,如图2和图4所示,至少一级旋风腔包括沿机罩2的周向依次布置的多个同级旋风风道A10,这样,从上一级旋风腔分离出的气流可以分别进入到多个旋风风道A10内、以进行独立的尘气分离,从而可以进一步提高尘气分离效果和净化效果。
优选地,最下游一级旋风腔包括沿机罩2的周向依次布置的多个最下游一级旋风风道A10,连通腔A2包括多个连通风道A20,多个连通风道A20与多个最下游一级旋风风道A10对应连通。例如在图4所示的示例中,当旋风分离腔为二级时,二级旋风腔A12包括多个旋风风道A10;而当旋风分离腔为三级时图未示出该示例,三级旋风腔包括多个旋风风道A10。
多个旋风风道A10与多个连通风道A20一一对应连通,例如在图3和图4所示的示例中,多个延伸段1211可以一一对应地配合在多个旋风风道A10内,以使多个入流连通孔12110分别一一对应地将多个旋风风道A10与多个连通风道A20连通在一起。由此,过滤效果更好。
例如在本发明的一些具体示例中,参照图3、图4和图7,第一旋风分离件41为环绕机罩2的多个旋风筒410,每个旋风筒410限定出一个旋风风道A10,由此,进入除尘腔A1内的尘气可以经过分别进入多个旋风筒410内进行独立的旋风式尘气分离,从而有效地提高了尘气分离效果,提高了手持吸尘器1000的吸尘效果。
优选地,参照图3、图4和图7,旋风筒410可以形成为立筒形,旋风筒410的侧壁可以敞开以形成为进气口,且进气口沿旋风筒410的切向延伸,且旋风筒410的顶端可以敞开以形成为出气口,旋风筒410的底端可以敞开以形成为出尘口,旋风筒410的顶端可以止抵在内盖121的底壁上,且一一对应地套设在多个延伸段1211外,也就是说,多个延伸段1211一一对应地伸入到多个旋风筒410内。
由此,参照图4和图9,由进气口进入旋风筒410的尘气可以旋风式流动,以将灰尘和气体分离开,分离出的灰尘可以通过旋风筒410底部的出尘口排出、沉积到除尘腔A1内的底部(例如沉积到下文所述的、限定在机罩2的第二筒段213与第二旋风分离件42的隔筒部421之间的二级积尘腔A13内),而分离出的气体可以通过旋风筒410顶部的出气口排出、流入机盖12中的连通腔A2内。
优选地,参照图3和图4,第一旋风分离件41包括沿机罩2轴向相连的直筒段411和锥筒段412,例如,当机罩2为立筒形时,直筒段411连接在锥筒段412的顶部,锥筒段412的横截面积自上向下逐渐减小。这样,进入旋风筒410内的尘气在旋风筒410内旋风式流动时,可以更加有效且可靠地进行尘气分离,提高尘气分离效果。
优选地,参照图3和图7,第一旋风分离件41与机罩2为一体件。由此,可以提高加工效率,而且可以省去装配第一旋风分离件41和机罩2的工序,提高组装效率,而且由于第一旋风分离件41与机罩2为一体件、模块化强,从而降低了装配难度,当用户拆卸尘杯组件100进行清洗后、还可以简便地将尘杯组件100组装起来。另外,当第一旋风分离件41与机罩2为一体件时,可以进一步提高尘杯组件100的结构紧凑性,使得尘杯组件100更加轻便小巧,而且可以提高除尘腔1的灰尘容量,同时在不提高成本的前提下,可以提高机罩2的强度。
例如在图7所示的示例中,第一旋风分离件41可以为一体成型在机罩2的外周壁上且环绕机罩2的多个旋风筒410。由此,更加有效地降低了装配难度,用户可以极其简便的完成尘杯组件100的拆装。这里,需要说明的是,在本文中,两个部件为“一体件”指的是两个部件不可拆分,两个部件“一体成型”指的是两个部件同时加工成型且为一个不可拆分的整体部件。
优选地,参照图1和图3,当机罩2为筒形时,在机罩2的轴向上、负压装置3的至少 部分位于第一旋风分离件41的一侧。由此,这样,负压装置3可以充分地利用机罩2内的空间,第一旋风分离件41可以充分利用机罩2外的空间,从而使得尘杯组件100的结构更加紧凑。这里,需要说明的是,图1和图2中未示出第一旋风分离件41。
可选地,参照图1,负压装置3包括沿机罩2轴向依次相连的风机31和电机32,在机罩2的轴向上,电机32和第一旋风分离件41间隔开,也就是说,电机32完全位于第一旋风分离件41的一侧,由此,可以更加充分地利用空间。另外,由于负压装置3由风机31和电机32组成,从而负压装置3的构成简单,便于获得。当然,本发明不限于此,负压装置3还可以由其他部件构成,例如,负压装置3还可以由真空泵等构成。
参照图1-图4,机罩2包括沿机罩2轴向依次相连的第一筒段211、过渡筒段212和第二筒段213,其中,第一筒段211的最大筒径小于第二筒段213的最小筒径,由此,当机罩2与壳体1为同轴设置的筒形、且除尘腔A1限定在壳体1的内周壁与机罩2的外周壁之间时,除尘腔A1的与第一筒段211径向相对的部分的容积可以大于除尘腔A1的与第二筒段213相对的部分的容积,且排气腔A3的与第二筒段213径向相对的部分的容积可以大于排气腔A3的与第一筒段211相对的部分的容积。
这样,在机罩2的径向上,当第一旋风分离件41与第一筒段211相对或与第一筒段211和过渡筒段212相对时,第一旋风分离件41可以充分地利用除尘腔A1的空间,以提高尘气过滤效果。同时,在机罩2的径向上,当负压装置3与第二筒段213相对或与第二筒段213和过渡筒段212相对时,负压装置3可以充分地利用排气腔A3的空间,以提高尘气过滤效果。
优选地,第二筒段213的轴向长度大于过渡筒段212的轴向长度,例如,第二筒段213的轴向长度可以为过渡筒段212的轴向长度的两倍以上,而第一筒段211的轴向长度可以大于等于过渡筒段212的轴向长度。由此,第一旋风分离件41和负压装置3可以更加充分地利用空间,提高手持吸尘器1000整体的吸尘效果。
优选地,参照图3,第一筒段211与第二筒段213均为直筒段411,过渡筒段212为渐扩筒段。由此,便于加工和装配,且当第一旋风分离件41一体成型在第一筒段211的外周壁上和过渡筒段212的外周壁上时,第一旋风分离件41可以自然成型为由多个直筒段411和多个锥筒段412对应拼接而成的多个旋风筒410,从而不但充分地利用了空间,而且提高了尘气分离效果。
例如在图3所示的实施例中,罩身21为立筒形且从上到下依次包括第一筒段211、过渡筒段212、第二筒段213,沿着从上向下的方向,第一筒段211的横截面积处处相等,过渡筒段212的横截面积逐渐增大、第二筒段213的横截面积处处相等。由此,加工方便,且便于多个旋风筒410的成型。
在本发明的一些实施例中,机罩2和第二旋风分离件42均立式设置,第二旋风分离件42的轴向两端分别止抵在壳体1的内壁面上,例如,在图1和图3所示的示例中,第二旋风分离件42的顶端止抵在内盖121的下表面上,第二旋风分离件42的底端止抵在壳体1的内底壁110上。
这样,第二旋风分离件42的外周壁与壳体1的内周壁之间可以限定出环柱形的一级除尘腔,第二旋风分离件42的内周壁与机罩2的外周壁之间可以限定出环柱形的二级除尘腔,一级除尘腔环绕二级除尘腔以与二级除尘腔共同限定出除尘腔。由此,由于一级除尘腔和二级除尘腔分别位于第二旋风分离件42的外内两侧且均为环柱形空间,从而可以有效地提高除尘腔的布局紧凑性,提高一级除尘腔和二级除尘腔的体积,使得尘气可以更加充分地分离。
其中,参照图3和图4,一级除尘腔可以全部为一级旋风腔A11,第一旋风分离件41可以设在二级除尘腔内,即设在第二旋风分离件42的内周壁与机罩2的外周壁之间,以在二级除尘腔内限定出二级旋风腔A12,此时,二级除尘腔内除二级旋风腔A12以外的部分 为二级积尘腔A13。
优选地,参照图1和图2,第二旋风分离件42立式设置,第二旋风分离件42包括轴向相连的隔筒部421和滤筒部422,其中,滤筒部422可以可拆卸地连接在隔筒部421的顶端,且滤筒部422上限定出连通一级旋风腔A11和二级旋风腔A12的过滤孔4221,其中,隔筒部421的底端可以止抵在壳体1的内底壁110上,滤筒部422的顶端可以止抵在内盖121的下表面上。由此,第二旋风分离件42由一个含孔的筒形件(即滤筒部422)和一个不含孔的筒形件(即隔筒部421)串接而成,从而第二旋风分离件42的结构简单,便于加工和制造。
当然,本发明不限于此,第二旋风分离件42还可以由其他部件构成,例如,第二旋风分离件42还可以由具有多个缺口的隔筒和分别嵌设在多个缺口内的滤片组成,这里不再详述。
优选地,第二旋风分离件42的至少部分与第一旋风分离件41为一体件,也就是说,第二旋风分离件42可以全部与第一旋风分离件41为一体件,第二旋风分离件42还可以仅有部分与第一旋风分离件41为一体件,例如,可以仅有隔筒部421与第一旋风分离件41为一体件,而滤筒部422与隔筒部421可拆卸地相连。由此,当第二旋风分离件42的至少部分与第一旋风分离件41为一体件时,可以进一步降低拆装难度,便于用户拆卸尘杯组件100进行清洗。
在本发明的一些实施例中,除尘装置4设在除尘腔A1内且在除尘腔A1内限定出至少一级圆环形或圆柱形的旋风腔,例如当除尘装置4包括多个旋风筒410时,旋风筒410可以限定出圆柱形的旋风腔,而当除尘装置4包括第二旋风分离件42时,第二旋风分离件42与壳体1之间可以限定出圆环形的旋风腔。
除尘装置4在除尘腔A1内进一步限定出与旋风腔连通的集尘槽4210。由此,当尘气在旋风腔内旋风式流动时,分离出的灰尘可以积聚在集尘槽4210内,以避免被流动的气流再次卷起,从而有效地提高了尘气分离效果。
例如在本发明的一些优选实施例中(图未示出),集尘槽4210由除尘装置4限定出,由此,方便加工,且方便实现。例如在其中的一个具体示例中,除尘装置4包括连续筒形过滤件,连续筒形过滤件为筒形且其上仅具有过滤孔4221(例如,上文所述的轴向相连的隔筒部421和滤筒部422可以共同组成连续筒形过滤件,其中,过滤孔4221可以形成在滤筒部421上),连续筒形过滤件套设在机罩2与壳体1之间以与壳体1之间限定出一级旋风腔A11,集尘槽4210由连续筒形过滤件的外周面向内凹入形成且与一级旋风腔A11连通,也就是说,连续筒形过滤件的外周面上具有朝向其中心轴线方向凹入的凹槽,该凹槽可以作为集尘槽4210。
例如在本发明的另一些优选实施例中,集尘槽4210由除尘装置4和机罩2共同限定出。由此,可以进一步提高结构的紧凑性,节省空间。例如在其中的一个具体示例中,参照图7和图8,除尘装置4包括分裂筒形过滤件,分裂筒形过滤件套设在机罩2与壳体1之间以与壳体1之间限定出一级旋风腔A11,分裂筒形过滤件为筒形且其上具有过滤孔4221和多个由分裂筒形过滤件的一个轴端面向另一个轴端面凹入的裂口,以使分裂筒形过滤件的至少部分分裂成多个裂片(例如,上文所述的轴向相连的隔筒部421和滤筒部422可以共同组成分裂筒形过滤件,其中,过滤孔4221可以形成在滤筒部422上,隔筒部421可以分裂成多个裂片),每个裂片的形成裂口的边沿向机罩2的方向弯折延伸且止抵在机罩2的外周面上,集尘槽4210由分裂筒形过滤件的分裂处与机罩2的外周面之间限定出且与一级旋风腔A11连通。
当然,本发明不限于此,在本发明的其他实施例中,参照图10,第二旋风分离件42上还可以不具有集尘槽4210,此时,隔筒部421可以形成为圆筒形。
参照图4,优选地,集尘槽4210沿机罩2的轴向延伸,其中,集尘槽4210的轴向两端 可以分别与隔筒部421的轴向两端平齐,也就是说,集尘槽4210的上下两端分别与隔筒部421的上下两端平齐,由此,可以提高进一步提高尘气分离效果。当然,本发明不限于此,集尘槽4210的轴向两端还可以不与隔筒部421的轴向两端平齐,此时,集尘槽4210的轴向长度短于隔筒部421的轴向长度。
优选地,参照图7,集尘槽4210为多个且在机罩2的周向上间隔开,例如集尘槽4210的数量可以为3个-8个,由此,可以进一步提高尘气分离效果。优选地,集尘槽4210在一级旋风分离件的径向上的深度L1为8mm-25mm,由此,可以提高尘气分离效果。优选地,集尘槽4210在一级旋风分离件的周向上的宽度L2为15mm-35mm,由此,可以提高尘气分离效果。
进一步地,参照图7,第二旋风分离件42进一步包括:檐圈部423,檐圈部423的内圈壁连接在隔筒部421与滤筒部422之间、外圈壁沿着从滤筒部422到隔筒部421的方向、朝向远离隔筒部421外周面的方向倾斜延伸。由此,参照图2和图4,进入一级旋风腔A11内的尘气在檐圈部423的引导下可以更好地进行尘气分离,而且,分离出的气体可以更加顺利地通过滤筒部422进入二级旋风腔A12,另外,分离出的灰尘难以再越过檐圈部423通过滤筒部422进入二级旋风腔A12,从而可以有效地提高尘气分离效果。
在本发明的一个实施例中,参照图3和图5,当壳体1为筒形时,壳体1的内周壁(即壳体1的内表面中不被其轴线贯穿的表面)上设有向壳体1内部延伸的第一挡尘片113。由此,灰尘在一级旋风腔A11内旋风式运动时,灰尘可以被第一挡尘片113截流,而不被气流反复卷起而阻塞过滤孔4221或进入二级旋风腔A12,从而提高尘气分离效果。
优选地,第一挡尘片113沿壳体1的轴向延伸。由此,当壳体1立式设置时,截流后的灰尘可以沿着第一挡尘片113向下流道壳体1底部,以避免灰尘被反复卷起而阻塞过滤孔4221或进入二级旋风腔A12,从而进一步提高了尘气分离效果。优选地,第一挡尘片113为多个且在壳体1的周向上间隔开。由此,在壳体1的整个周向上,第一挡尘片113都可以起到有效地截流作用,从而进一步提高尘气分离效果。
在本发明的一个实施例中,参照图1和图6,壳体1为筒形,壳体1的内端壁(即壳体1的内表面中被其轴线贯穿的两个表面之一)上设有向壳体1内部延伸的第二挡尘片114。例如,当壳体1立式设置时,第二挡尘片114可以由壳体1的内底壁110向上延伸。由此,灰尘在一级旋风腔A11内旋风式运动时,灰尘可以被第二挡尘片114截流,而不会被反复卷起而阻塞过滤孔4221或进入二级旋风腔A12,进而提高尘气分离效果。
优选地,第二挡尘片114沿壳体1的径向延伸。由此,在壳体1的整个径向上,第二挡尘片114都可以起到有效地截流作用,从而进一步提高尘气分离效果。优选地,第二挡尘片114为多个且在壳体1的周向上间隔开。由此,在壳体1的整个周向上,第二挡尘片114都可以起到有效地截流作用,从而进一步提高尘气分离效果。

参照图2、并结合图4和图9,尘气由吸尘口112沿切向进入一级除尘腔内A11内进行旋风式尘气分离,在此过程中,旋风式分离出的部分灰尘进入并积聚在集尘槽4210内、其余部分灰尘降落并积聚在一级除尘腔内A11的底部,而旋风分离出的气流通过过滤孔4221沿切向进入二级除尘腔内A12内进行旋风式尘气分离,在此过程中,旋风式分离出的灰尘降落并积聚在二级积尘腔A13内,而旋风分离出的气流通过入流连通孔12110进入连通腔A2内由盖内过滤件1221进行过滤,过滤后的气流通过出流连通孔12120进入排气腔A3内,并通过罩内过滤件25过滤后由排气口220和开口111排出。
下面参考附图1描述根据本发明一些实施例手柄组件200。
具体地,持握组件具有方便用户手持的功能,例如持握组件可以为提手或手柄组件200等。其中,当持握组件为手柄组件200时,便于用户控制尘杯组件100的朝向,例如方便用户将尘杯组件100的吸尘口112朝上或朝下,从而方便吸尘。下面仅以持握组件为手柄 组件200为例进行说明。另外,需要说明的是,提手的结构应为本领域技术人员所熟知,这里不再详述。
如图1所示,手柄组件200包括:手柄壳51和供电装置52,手柄壳51包括供用户手持的持握部512,供电装置52可以设在持握部512内,供电装置52还可以设在手柄壳51内的与持握部512相对的位置、例如下文所述的安装部511内,由此,可以优化手柄组件200的重心,使手柄组件200的重心更加靠近用户手持的位置,从而使用户可以更加省力地手持手柄组件200,提高手持吸尘器1000的使用舒适性和便捷性。
其中,供电装置52可以为电池,例如,充电电池,从而容易实现,成本低,且便于使用。
如图1所示,手柄壳51上具有指扣部510,手柄壳51包括位于指扣部510两侧、且用于与尘杯组件100相连的安装部511和用于手握的持握部512,供电装置52设在安装部511内和/或持握部512内。由此,手柄壳51的结构简单,便于加工和制造。可选地,指扣部510为握孔,手柄壳51为环形壳体,握孔由手柄壳51的内环限定出。由此,便于持握,且便于供电装置52的安装。
优选地,供电装置52设在安装部511内且供电装置52的长度方向与安装部511的长度方向相同。由此,供电装置52可以充分地利用安装部511内的空间,使手柄组件200可以更加小型化,且可以使用户更加省力地持握手柄组件200。
优选地,供电装置52设在持握部512内且供电装置52的长度方向与持握部512的长度方向相同。由此,供电装置52可以充分地利用持握部512内的空间,使手柄组件200可以更加小型化,且可以使用户更加省力地持握手柄组件200。
优选地,尘杯组件100为筒形,安装部511的长度方向与尘杯组件100的轴向相同,且安装部511连接在手柄组件200的径向一侧。由此,可以提高安装部511与尘杯组件100的连接面积,提高手柄组件200与尘杯组件100的连接可靠性,且持握更加省力。可选地,安装部511与尘杯组件100可拆卸地相连。也就是说,手柄组件200可拆卸地安装在尘杯组件100上。由此,可以便于拆装、清洗和更换。
进一步地,参照图1,手柄壳51进一步包括连接在安装部511和持握部512之间且相对设置的柄顶部513和柄底部514,也就是说,安装部511、柄顶部513、持握部512和柄底部514首尾顺次相连以构成环形手柄壳51,从而,手柄壳51的结构可靠性高。当然,本发明不限于此,手柄壳51还可以不为环形、即可以不包括柄顶部513和柄底部514,此时,手柄壳51可以由相对设置的安装部511、持握部512和连接在安装部511和持握部512之间的搭桥部构成工字形等图未示出该示例。
优选地,柄顶部513内可以设有与供电装置52相连的电控板53、柄底部514内也可以设有与供电装置52相连的电控板53,柄顶部513和柄底部514内还可以同时都设有与供电装置52相连的电控板53。由此,可以更加充分地利用手柄壳51内部的空间。
下面参考附图16-图18、并结合图1-图10描述根据本发明一些实施例的手持吸尘器1000。
如附图所示,根据本发明实施例的手持吸尘器1000,包括:壳体1、负压装置3、第一检测装置500A以及控制装置。
壳体1内可以具有进气风道,其中,进气风道指的是环境中的尘气进入壳体1内未被过滤之前所流经的通道。负压装置3设在壳体1内且用于使壳体1外的尘气进入进气风道内。例如在本发明的一个具体示例中,壳体1可以包括本文的壳体1和手柄壳51,壳体1上具有吸气口112,吸尘口112的内孔限定出进气风道。其中,负压装置3可以包括风机31和与风机31相连的电机32,负压装置3的吸气力度由电机32的运行功率决定,也就是说,当电机32的运行功率越高时,风机31的转速越快,负压装置3的吸气力度越大;而当电机32的运行功率越低时,风机31的转速越低,负压装置3的吸气力度越小。
第一检测装置500A设在壳体1上且用于检测壳体1的移动状态,即用于检测壳体1是否移动、以及检测壳体1的移动速度快慢,例如,第一检测装置500A可以为加速度传感器或速度传感器等。控制装置分别与第一检测装置500A和负压装置3相连,例如控制装置可以为手持吸尘器1000的PCB板等,且控制装置构造成根据第一检测装置500A检测到的信息控制手持吸尘器1000的工作状态、例如控制手持吸尘器1000切换到下文所述的开机状态、关机状态、休眠待机状态、高吸力状态、低吸力状态等。
由此,根据本发明实施例的手持吸尘器1000,可以根据其移动状态的改变自动智能切换到相应的工作状态,以兼顾吸尘效果和节能效果。
例如在本发明的一些具体示例中,控制装置可以构造成在第一检测装置500A检测到壳体1的移动速度升高时控制负压装置3提高吸气力度。也就是说,当第一检测装置500A检测到用户携持手持吸尘器1000加快速度移动时,控制装置调高负压装置3的吸气力度,以确保吸尘效果。
例如在本发明的一些具体示例中,控制装置可以构造成在第一检测装置500A检测到壳体1的移动速度下降时控制负压装置3降低吸气力度。也就是说,当第一检测装置500A检测到用户携持手持吸尘器1000减慢速度移动时,控制装置调低负压装置3的吸气力度,以降低能耗。
例如在本发明的一些具体示例中,控制装置构造成在第一检测装置500A检测到壳体1的移动速度高于第一预设值时控制负压装置3以第一吸气力度运行、且在第一检测装置500A检测到壳体1的移动速度低于第二预设值时控制负压装置3以第二吸气力度运行,其中,第一预设值大于等于第二预设值,第一吸气力度大于等于第二吸气力度。也就是说,当第一检测装置500A检测到手持吸尘器1000的移动速度较高时,手持吸尘器1000可以自动智能切换到高吸力状态;而当第一检测装置500A检测到手持吸尘器1000的移动速度较低时,手持吸尘器1000可以自动智能切换到低吸力状态。
由此,当第一检测装置500A检测到用户携持手持吸尘器1000以较高的速度移动时,控制装置可以控制负压装置3以较高的吸气力度吸尘,以确保吸尘效果;而当第一检测装置500A检测到用户携持手持吸尘器1000以较低的速度移动时,控制装置可以控制负压装置3以较低的吸气力度吸尘,以降低能耗。
例如在本发明的一些具体示例中,在负压装置3运行中的第一预定时长(例如1s)内、控制装置构造成在第一检测装置500A检测到壳体1始终没有产生位移时控制负压装置3停机,也就是说,在手持吸尘器1000处于开机状态时,如果经过第一预定时长,用户没有携持手持吸尘器1000移动、第一检测装置500A没有检测到手持吸尘器1000发生位移,此时,控制装置控制手持吸尘器1000进入休眠待机状态,即负压装置3停止工作、而第一检测装置500A仍然工作。由此,当用户将手持吸尘器1000暂时放置一边去做其他事情时,手持吸尘器1000可以自动智能进入休眠待机状态,从而节省不必要的能耗,且方便用户回来继续使用。
进一步地,在负压装置3停机后的第二预定时长(例如10min)内、控制装置构造成在第一检测装置500A检测到壳体1产生位移时控制负压装置3开机。也就是说,在手持吸尘器1000进入休眠待机状态后,如果在第二预定时长内,用户携持手持吸尘器1000移动、第一检测装置500A检测到手持吸尘器1000发生位移,此时,控制装置控制手持吸尘器1000进入开机状态,即负压装置3开始工作,第一检测装置500A仍然工作,控制装置根据第一检测装置500A检测到的信息控制手持吸尘器1000的工作状态。由此,当用户回到手持吸尘器1000处继续使用时,手持吸尘器1000可以自动智能开机,从而方便用户使用。
再进一步地,在负压装置3停机后的第二预定时长(例如10min)内、控制装置构造成在第一检测装置500A检测到壳体1始终没有产生位移时控制手持吸尘器1000关机。也 就是说,在手持吸尘器1000进入休眠待机状态后,如果经过第二预定时长,用户没有携持手持吸尘器1000移动、第一检测装置500A检测到手持吸尘器1000始终没有发生位移,此时,控制装置控制手持吸尘器1000进入关机状态,即负压装置3停止工作,第一检测装置500A停止工作,控制装置不再根据第一检测装置500A检测到的信息控制手持吸尘器1000的工作状态。由此,在用户离开手持吸尘器1000而忘记关闭手持吸尘器1000时,手持吸尘器1000可以自动智能关机,从而节省不必要的能耗。
这里,需要说明的是,本文中所述的第一预设值和第二预设值均可以根据实际要求设定,例如可以在手持吸尘器1000出厂前由设计人员预先设定完成,也可以在手持吸尘器1000出场后由用户自行设定调整,同时,第一吸气力度和第二吸气力度均可以根据实际要求设定,例如可以在手持吸尘器1000出厂前由设计人员预先设定完成,也可以在手持吸尘器1000出场后由用户自行设定调整。
这里,需要说明的是,第一预定时长和第二预定时长均可以根据实际要求设定,例如可以在手持吸尘器1000出厂前由设计人员预先设定完成,也可以在手持吸尘器1000出场后由用户自行设定调整。
这里,需要说明的是,本文中所述的“开机状态”指的是:手持吸尘器1000可以进行吸尘工作,且手持吸尘器1000可以通过检测手持吸尘器1000的移动状态使手持吸尘器1000切换到相应的工作状态;“休眠待机状态”指的是:手持吸尘器1000不可以进行吸尘工作;其中,“关机状态”指的是:手持吸尘器1000不可以进行吸尘工作,且手持吸尘器1000不可以通过检测手持吸尘器1000的移动状态使手持吸尘器1000切换到相应的工作状态。
在本发明的一些实施例中,手持吸尘器1000还包括:控制键,控制键与控制装置相连且构造成单次(例如第一次、第三次、第五次等等)被触发后控制控制装置开始根据第一检测装置500A检测到的信息控制手持吸尘器1000的工作状态,且在控制键双次(例如第二次、第四次、第六次等等)被被触发后控制装置停止根据第一检测装置500A检测到的信息控制手持吸尘器1000的工作状态。其中,控制键可以设在壳体1上也可以设在其他位置,例如为手机APP上的虚拟按键等。
也就是说,只有在用户单次触发控制键后,控制装置才开始根据第一检测装置500A检测到的信息控制手持吸尘器1000的工作状态、即进入节能模式,而在用户未触发控制键前或双次触发控制键时,即便第一检测装置500A进行检测,控制装置也不会根据第一检测装置500A检测到的信息控制手持吸尘器1000的工作状态、即停止节能模式。由此,可以给用户提供更多的选择,提高用户使用手持吸尘器1000的愉悦性,同时通过一个控制键的多次触发实现进入节能模式和停止节能模式的切换,可以节省控制键的占用空间,提高简洁性。
在本发明的另一些实施例中,手持吸尘器1000还包括:开启控制键和关闭控制键,开启控制键与控制装置相连且构造成被触发后控制控制装置开始根据第一检测装置500A检测到的信息控制手持吸尘器1000的工作状态,关闭控制键与控制装置相连且构造成被触发后控制控制装置停止根据第一检测装置500A检测到的信息控制手持吸尘器1000的工作状态。其中,开启控制键和关闭控制键可以设在壳体1上也可以设在其他位置,例如为手机APP上的虚拟按键等。
也就是说,在用户触发开启控制键后,控制装置才开始根据第一检测装置500A检测到的信息控制手持吸尘器1000的工作状态、即进入节能模式,在用户触发关闭控制键后,即便第一检测装置500A进行检测,控制装置也不会根据第一检测装置500A检测到的信息控制手持吸尘器1000的工作状态、即停止节能模式。由此,可以给用户提供更多的选择,提高用户使用手持吸尘器1000的愉悦性,同时通过开启控制键和关闭控制键两个按键实现进入节能模式和停止节能模式的切换,可以提高操作的准确可靠性,降低误操作概率。
综上所述,在本发明的一些具体实施例中的手持吸尘器1000,通过在手持吸尘器1000 上设置可以感知位移、例如速度或加速度的传感器芯片,从而当手持吸尘器1000以较低的位移速度清洁时,主控PCB板可以自动控制电机32以较小的功率工作,使手持吸尘器1000的输出功率很小,而当手持吸尘器1000以较高的位移速度清洁时,主控PCB板自动控制电机32以较大的功率工作,手持吸尘器1000的输出功率大,从而提高吸尘能力和吸尘效率,并且节能省电。同时,当手持吸尘器1000在设定时间内(如:1秒)没有位移,手持吸尘器1000可以自动进入休眠待机状态,在手持吸尘器1000处于休眠待机状态时,如果手持吸尘器1000有位移,手持吸尘器1000自动切换到开机状态,而在手持吸尘器1000处于休眠待机状态时,如在一定的时间内(如:10分钟)内手持吸尘器1000没有位移,手持吸尘器1000则自动关机、即进入关机状态,从而达到节能省电的效果。由此,手持吸尘器1000可以同时兼顾提高吸尘效率和节能省电双重有益效果。

在本发明的一些实施例中,手持吸尘器1000的控制方法还可以包括步骤:在检测到手持吸尘器1000的移动速度低于第二预设值时控制手持吸尘器1000以第二吸气力度运行。也就是说,当检测到用户携持手持吸尘器1000以较低的速度移动时,控制手持吸尘器1000切换到低吸力状态,从而手持吸尘器1000可以以较低的吸气力度吸尘,以降低能耗。
在本发明的一些实施例中,手持吸尘器1000的控制方法还可以包括步骤:在手持吸尘器1000处于开机状态时的第一预定时长(例如1s)内,如果检测到手持吸尘器1000始终没有产生位移则控制手持吸尘器1000进入休眠待机状态。
也就是说,在手持吸尘器1000处于开机状态时,如果经过第一预定时长,始终没有检 测到用户携持手持吸尘器1000发生移动,例如,用户将手持吸尘器1000暂时放置一边去做其他事情时,此时,可以控制手持吸尘器1000进入休眠待机状态,从而节省不必要的能耗,且方便用户回来继续使用。
进一步地,手持吸尘器1000的控制方法还可以包括步骤:在手持吸尘器1000处于休眠待机状态时的第二预定时长内,在检测到手持吸尘器1000产生位移时控制手持吸尘器1000进入开机状态。也就是说,在手持吸尘器1000处于休眠待机状态时,如果经过第二预定时长,检测到用户携持手持吸尘器1000移动,例如,用户回到手持吸尘器1000处继续使用时,此时,可以控制手持吸尘器1000重新进入开机状态,从而方便用户使用。
进一步地,手持吸尘器1000的控制方法还可以包括步骤:在手持吸尘器1000处于休眠待机状态时的第二预定时长内,如果检测到手持吸尘器1000始终没有产生位移则控制手持吸尘器1000进入关机状态。也就是说,在手持吸尘器1000处于休眠待机状态时,如果经过第二预定时长,始终没有检测到用户携持手持吸尘器1000发生移动,例如,用户离开手持吸尘器1000而忘记关闭手持吸尘器1000时,此时,可以控制手持吸尘器1000进入关机状态,从而节省不必要的能耗。
在本发明的一些实施例中,手持吸尘器1000的控制方法还可以包括步骤:接收开启节能指令,在接收到开启节能指令后开始根据检测到的移动状态控制手持吸尘器1000的工作状态。也就是说,只有在接收到开启节能指令后,才开始根据检测到的信息控制手持吸尘器1000的工作状态、即进入节能模式。由此,可以给用户提供更多的选择,提高用户使用手持吸尘器1000的愉悦性。
在本发明的一些实施例中,手持吸尘器1000的控制方法还可以包括步骤:接收关闭节能指令,在接收到关闭节能指令后停止根据检测到的移动状态控制手持吸尘器1000的工作状态。也就是说,只有在接收到关闭节能指令后,即便检测到的信息,也不控制手持吸尘器1000切换工作状态、即不进入节能模式。由此,可以更好地适应用户的实际需求。
例如在本发明的一些具体示例中,开启节能指令的接收和关闭节能指令的接收可以集成在一个键上,例如都集成在上文所述的控制键上,当单次(例如第一次、第三次、第五次等等)触发控制键,可以接收到开启节能指令,以使手持吸尘器1000进入节能模式,当双次(例如第二次、第四次、第六次等等)触发控制键,可以接收到关闭节能指令,以使手持吸尘器1000停止节能模式。

壳体1内可以具有进气风道,其中,进气风道指的是环境中的尘气进入壳体1内未被过滤之前所流经的通道。负压装置3设在壳体1内且用于使壳体1外的尘气进入进气风道内。例如在本发明的一个具体示例中,壳体1可以包括本文的壳体1和手柄壳51,壳体1上具有吸气口112,吸尘口112的内孔限定出进气风道。其中,负压装置3可以包括风机31和与风机31相连的电机32,负压装置3的吸气力度由电机32的运行功率决定,也就是说,当电机32的运行功率越高时,风机31的转速越快,负压装置3的吸气力度越大;而当电机32的运行功率越低时,风机31的转速越低,负压装置3的吸气力度越小。
第二检测装置500B设在壳体1上且用于检测进气风道内的灰尘浓度,其中,“进气风道内的灰尘浓度”指的是:进气风道某一截面上的灰尘浓度、或者进气风道内的某一段截面内的平均灰尘浓度、或者整个进气风道内的平均灰尘浓度,其中,“某一截面上的灰尘浓 度”指的是:某一截面内的气体中所含灰尘占该截面的面积比。
例如在本发明的一个具体示例中,第二检测装置500B可以包括发射器501B和接收器502B,发射器501B和接收器502B相对设置以使进入进气风道内的灰尘经由发射器501B和接收器502B之间通过。其中,发射器501B和接收器502B可以均设在进气风道内的两侧,例如设在吸尘口112内且分别位于吸尘口112直径上的两端。
其中,发射器501B可以用于向接收器502B发射光线,接收器502B用于接收发射器501B发出的光线,当灰尘流经发射器501B和接收器502B之间时,灰尘会阻挡一些光线被接收器502B接收,从而接收器502B接收到的光线总量变少,这样,当流经发射器501B和接收器502B之间的灰尘浓度较高时,接收器502B接收到的光线总量较少,而当流经发射器501B和接收器502B之间的灰尘浓度较低时,接收器502B接收到的光线总量较多。由此,可以简单、可靠地根据接收器502B接收到的光线量判断流经发射器501B和接收器502B之间的灰尘浓度。这里,需要说明的是,发射器501B和接收器502B的结构应为本领域技术人员所熟知,这里不再详述。
当然,本发明不限于此,第二检测装置500B还可以为其他装置。例如在本发明的另一个具体示例中,第二检测装置500B还可以为图像检测系统、例如包括摄像头和数据终端,摄像头可以拍摄进气风道内的灰尘情况,数据终端可以根据摄像头拍摄的图片信息进行计算分析以得到进气风道的灰尘浓度。例如在本发明的再一个具体示例中,第二检测装置500B还可以为重量检测系统、例如包括灵敏称和数据终端,灵敏称可以设在进气风道的底部以监测进气风道内的重量变化,由于灰尘的重量大于气体的重量,进气风道内的重量变化主要是灰尘的重量变化,从而数据终端可以根据灵敏称称得的重量信息进行计算分析以得到进气风道内的灰尘浓度变化。
控制装置分别与第二检测装置500B和负压装置3相连,例如控制装置可以为手持吸尘器1000的PCB板等,且控制装置构造成根据第二检测装置500B检测到的信息控制手持吸尘器1000的工作状态、例如控制手持吸尘器1000切换到下文的高吸力状态或低吸力状态等。由此,根据本发明实施例的手持吸尘器1000,可以根据吸气通道内的灰尘浓度改变自动智能切换到相应的工作状态,以兼顾吸尘效果和节能效果。
例如在本发明的一些具体示例中,控制装置可以构造成在第二检测装置500B检测到灰尘浓度升高时控制负压装置3提高吸气力度。也就是说,当第二检测装置500B检测到进气风道内的灰尘浓度变高时,控制装置调高负压装置3的吸气力度,以确保吸尘效果。
例如在本发明的一些具体示例中,控制装置可以构造成在第二检测装置500B检测到灰尘浓度下降时控制负压装置3降低吸气力度。也就是说,当第二检测装置500B检测到进气风道内的灰尘浓度变低时,控制装置调低负压装置3的吸气力度,以降低能耗。
例如在本发明的一些具体示例中,控制装置构造成在第二检测装置500B检测到灰尘浓度高于第一预设值时控制负压装置3以第一吸气力度运行、且在第二检测装置500B检测到灰尘浓度低于第二预设值时控制负压装置3以第二吸气力度运行,其中,第一预设值大于等于第二预设值,第一吸气力度大于等于第二吸气力度。也就是说,当第二检测装置500B检测到进气风道内的灰尘浓度较高时,手持吸尘器1000可以自动智能切换到高吸力状态;而当第二检测装置500B检测到进气风道内的灰尘浓度较低时,手持吸尘器1000可以自动智能切换到低吸力状态。
由此,当待清洁表面灰尘较多、第二检测装置500B检测到进气风道内的灰尘浓度较高时,控制装置可以控制负压装置3以较高的吸气力度吸尘,以确保吸尘效果;而当待清洁表面灰尘较少、第二检测装置500B检测到进气风道内的灰尘浓度较低时,控制装置可以控制负压装置3以较低的吸气力度吸尘,以降低能耗。
这里,需要说明的是,本文中的第一预设值和第二预设值均可以根据实际要求设定,例如可以在手持吸尘器1000出厂前由设计人员预先设定完成,也可以在手持吸尘器1000 出场后由用户自行设定调整,同时,第一吸气力度和第二吸气力度均可以根据实际要求设定,例如可以在手持吸尘器1000出厂前由设计人员预先设定完成,也可以在手持吸尘器1000出场后由用户自行设定调整。
在本发明的一些实施例中,手持吸尘器1000还包括:控制键,控制键与控制装置相连且构造成单次(例如第一次、第三次、第五次等等)被触发后控制控制装置开始根据第二检测装置500B检测到的信息控制手持吸尘器1000的工作状态,且在控制键双次(例如第二次、第四次、第六次等等)被触发后控制装置停止根据第二检测装置500B检测到的信息控制手持吸尘器1000的工作状态。其中,控制键可以设在壳体1上也可以设在其他位置,例如为手机APP上的虚拟按键等。
也就是说,只有在用户单次触发控制键后,控制装置才开始根据第二检测装置500B检测到的信息控制手持吸尘器1000的工作状态、即进入节能模式,而在用户未触发控制键前或双次触发控制键时,即便第二检测装置500B进行检测,控制装置也不会根据第二检测装置500B检测到的信息控制手持吸尘器1000的工作状态、即停止节能模式。由此,可以给用户提供更多的选择,提高用户使用手持吸尘器1000的愉悦性,同时通过一个控制键的多次触发实现进入节能模式和停止节能模式的切换,可以节省控制键的占用空间,提高简洁性。
在本发明的另一些实施例中,手持吸尘器1000还包括:开启控制键和关闭控制键,开启控制键与控制装置相连且构造成被触发后控制控制装置开始根据第二检测装置500B检测到的信息控制手持吸尘器1000的工作状态,关闭控制键与控制装置相连且构造成被触发后控制控制装置停止根据第二检测装置500B检测到的信息控制手持吸尘器1000的工作状态。其中,开启控制键和关闭控制键可以设在壳体1上也可以设在其他位置,例如为手机APP上的虚拟按键等。
也就是说,在用户触发开启控制键后,控制装置才开始根据第二检测装置500B检测到的信息控制手持吸尘器1000的工作状态、即进入节能模式,在用户触发关闭控制键后,即便第二检测装置500B进行检测,控制装置也不会根据第二检测装置500B检测到的信息控制手持吸尘器1000的工作状态、即停止节能模式。由此,可以给用户提供更多的选择,提高用户使用手持吸尘器1000的愉悦性,同时通过开启控制键和关闭控制键两个按键实现进入节能模式和停止节能模式的切换,可以提高操作的准确可靠性,降低误操作概率。
综上,在本发明的一些具体实施例中的手持吸尘器1000,通过在吸入灰尘经过的风道两侧分别设置发射传感器和接收传感器,当灰尘经过两个传感器之间的风道时,传感器可以感知灰尘的多少,并将灰尘多少的信号传输给主控PCB板,主控PCB板根据信号调节电机32输出的功率大小,从而提高吸尘效率,并且节能省电。
下面,简要描述根据本发明一些扩展实施例的手持吸尘器1000的控制方法。
具体地,手持吸尘器1000的控制方法可以包括如下步骤:
首先,(步骤A)检测手持吸尘器1000的灰尘吸入浓度,也就是说,检测手持吸尘器1000的进气风道内的灰尘浓度,然后,(步骤B)根据检测到的灰尘吸入浓度控制手持吸尘器1000的工作状态、例如控制手持吸尘器1000切换到上文的高吸力状态或低吸力状态等。由此,根据本发明实施例的手持吸尘器1000的控制方法,可以根据吸气通道内的灰尘浓度改变自动智能切换到相应的工作状态,以兼顾吸尘效果和节能效果。
这里,需要说明的是,上述步骤A可以通过上文的第二检测装置500B实现检测,当然,还可以通过其他方式实现检测,例如,可以通过在室内设置可以拍摄手持吸尘器1000待清洁表面灰尘情况的摄像装置,并通过与该摄像装置相连的终端判断手持吸尘器1000的灰尘吸入浓度。上述步骤B可以通过上文的控制装置实现控制,当然,还可以通过其他方式实现控制,例如,可以通过远程终端或者遥控设备进行控制。
在本发明的一些实施例中,手持吸尘器1000的控制方法还可以包括步骤:在检测到手 持吸尘器1000的灰尘吸入浓度升高时控制手持吸尘器1000提高吸气力度。也就是说,当检测到灰尘吸入浓度升高时,控制手持吸尘器1000的吸气力度提高,以确保吸尘效果。
在本发明的一些实施例中,手持吸尘器1000的控制方法还可以包括步骤:在检测到手持吸尘器1000的灰尘吸入浓度下降时控制手持吸尘器1000降低吸气力度。也就是说,当检测到灰尘吸入浓度下降时,控制手持吸尘器1000的吸气力度降低,以降低能耗。
在本发明的一些实施例中,手持吸尘器1000的控制方法还可以包括步骤:在检测到灰尘浓度高于第一预设值时控制负压装置3以第一吸气力度运行。也就是说,当检测到的灰尘浓度较高、即待清洁表面灰尘较多时,控制手持吸尘器1000切换到高吸力状态,从而手持吸尘器1000可以以较高的吸气力度吸尘,以确保吸尘效果。
在本发明的一些实施例中,手持吸尘器1000的控制方法还可以包括步骤:在检测到灰尘浓度低于第二预设值时控制负压装置3以第二吸气力度运行。也就是说,当检测到的灰尘浓度较低、即待清洁表面灰尘较少时,控制手持吸尘器1000切换到低吸力状态,从而手持吸尘器1000可以以较低的吸气力度吸尘,以降低能耗。
在本发明的一些实施例中,手持吸尘器1000的控制方法还可以包括步骤:接收开启节能指令,在接收到开启节能指令后开始根据检测到的灰尘吸入浓度控制手持吸尘器1000的工作状态。也就是说,只有在接收到开启节能指令后,才开始根据检测到的信息控制手持吸尘器1000的工作状态、即进入节能模式。由此,可以给用户提供更多的选择,提高用户使用手持吸尘器1000的愉悦性。
在本发明的一些实施例中,手持吸尘器1000的控制方法还可以包括步骤:接收关闭节能指令,在接收到关闭节能指令后停止根据检测到的灰尘吸入浓度控制手持吸尘器1000的工作状态。也就是说,只有在接收到关闭节能指令后,即便检测到信息,也不控制手持吸尘器1000切换工作状态、即不进入节能模式。由此,可以更好地适应用户的实际需求。
例如在本发明的一些具体示例中,开启节能指令的接收和关闭节能指令的接收可以集成在一个键上,例如都集成在上文的控制键上,当单次(例如第一次、第三次、第五次等等)触发控制键,可以接收到开启节能指令,以使手持吸尘器1000进入节能模式,当双次(例如第二次、第四次、第六次等等)触发控制键,可以接收到关闭节能指令,以使手持吸尘器1000停止节能模式。
例如在本发明的一些具体示例中,开启节能指令的接收和关闭节能指令的接收还可以集成在两个键上,例如分别集成在上文所述的开启控制键上和关闭控制键上,当触发开启控制键,可以接收到开启节能指令,以使手持吸尘器1000进入节能模式,当触发关闭控制键上,可以接收到关闭节能指令,以使手持吸尘器1000停止节能模式。
综上所述,根据本发明一些具体实施例的手持吸尘器1000,具有以下几方面优势。
a、通过将负压装置3设置在壳体1内,从而使得尘杯组件100的整体结构布局紧凑,小巧轻便,使用舒适度高,且使得尘杯组件100的风道布局紧凑、吸力损耗小、能效高。
b、通过在壳体1内设置旋风分离装置,从而提高了手持吸尘器1000的清洁效果,而且当除尘装置4环绕负压装置3时,可以降低手持吸尘器1000的工作噪声,提高手持吸尘器1000的环境友好性。
c、当负压装置3与机罩2为一体件时,可以有效地节省空间,进一步提高尘杯组件100的结构紧凑性,而且可以提高灰尘容量,在不增加成本的前提下,可以有效地提高机罩2强度,使得机罩2可以更好地保护负压装置3,提高负压装置3的使用寿命。
d、尘杯组件100中除了为一体件以外的各部件,都采用可拆卸的方式连接,从而使得尘杯组件100极其便于拆装,且可以进行选择性拆装,以便于对手持吸尘器1000内部构件进行针对性清洗,提高手持吸尘器1000的清洁效果。
e、通过使电机32与旋风筒410轴向间隔开,从而可以更加充分地利用壳体1内的空间,提高吸尘效果。
f、通过将排气口220设在尘杯组件100的底部,从而经尘杯组件100过滤后的清洁空气可以向下吹出,进而避免了尘杯组件100向用户者吹风的问题,提高了手持吸尘器1000的使用舒适性,使得用户愿意使用手持吸尘器1000进行清洁。
g、通过设置集尘槽4210,从而使得积聚在集尘槽4210内的灰尘可以避开壳体1内流动的气流,而不易被反复卷起阻塞过滤件或进入下一级旋风腔,而且,当集尘槽4210内的灰尘积聚一定量后,可以粘附集尘槽4210外的灰尘,防止灰尘被吹起,从而提高了清洁效果。另外,通过在壳体1内设置第一挡尘片113和第二挡尘片114,可以进一步阻挡灰尘被反复卷起阻塞过滤件或进入下一级旋风腔,从而提高了清洁效果。
h、通过将手柄组件200的重心升高,从而使得手持吸尘器1000整体持握更加省力。
I、延伸管300一方面可以提升手持吸尘器1000整体的吸气角度范围,另一方面可以从尘杯组件100上拆卸下来单独使用。
j,通过设置第一检测装置500A,手持吸尘器1000可以根据其自身移动情况自动调节工作状态,从而兼顾吸尘和节能双重效果。
k,通过设置第二检测装置500B,手持吸尘器1000可以根据灰尘吸入浓度情况自动调节工作状态,从而兼顾吸尘和节能双重效果。
实施例二、
下面,参照附图20和图21,描述根据本发明实施例的手持吸尘器W。
如图20和图21所示,手持吸尘器W包括尘杯组件WD和手柄组件WE,其中,尘杯组件WD包括壳体D1、除尘装置D2和负压装置D3,壳体D1上可以具有吸气口和排气口,负压装置D3设置在壳体D1内部且用于将环境中的尘气从吸气口吸入壳体D1内部,除尘装置D2设置在壳体D1内部且用于对吸入到壳体D1内的气流进行尘气分离,分离出的气流可以在负压装置D3的作用下从排气口排出到壳体D1外,而分离出的尘质可以存留在壳体D1内部。这里,需要说明的是,手持吸尘器指的是,用户可以通过手持动作将整机拿起的吸尘器,即区别于现有技术中整机需要在支撑面上推动的吸尘器。
参照图20和图21,手柄组件WE安装在尘杯组件WD上、例如可以安装在壳体D1上且用于手持,也就是说,用户可以通过持握手柄组件WE来拿起尘杯组件WD,从而进行清洁作业。另外,可选地,手柄组件WE可以包括手柄壳E1和供电装置E2,其中,手柄壳E1设在壳体D1上且用于手持,供电装置E2安装在手柄壳E1上且与负压装置D3电性相连,由此,供电装置E2可以向负压装置D3提供电能,而且,由于供电装置E2安装在手柄组件WE的手柄壳E1上,负压装置D3安装在尘杯组件WD的壳体D1内,从而可以优化手持吸尘器W的整体重心,使用户可以更加轻松省力地持握手持吸尘器W。
下面,参照图20和图21,描述根据本发明实施例的尘杯组件WD。
参照图20和图21,尘杯组件WD包括:壳体D1、负压装置D3和除尘装置D2,其中,壳体D1包括:杯身D11和机盖D12,杯身D11内限定出顶部敞开的容纳空间,负压装置D3和除尘装置D2均安装在杯身D11内部的容纳空间内且除尘装置D2位于负压装置D3的上方。
例如在图20和图21所示的示例中,杯身D11内具有排气腔D101、除尘腔D102和集尘腔D103,其中,排气腔D101为立柱形(横截面不限于圆形、多边形等规则形状),除尘腔D102(横截面也不限于闭合圆环形、闭合多边环形,例如还可以是不规则的环形)环绕排气腔D101一周,集尘腔D103位于除尘腔D102和排气腔D101的下方,除尘装置D2设在除尘腔D102内,负压装置D3设在集尘腔D103内且与排气腔D101连通。
如图20和图21所示,机盖D12可开关地设在杯身D11的上方以打开和关闭容纳空间,除尘装置D2为可取出设计,也就是说,除尘装置D2是可拆卸地设在壳体D1内的。由此,当需要清洁手持吸尘器W时,用户可以自行将机盖D12打开并将处于上方的除尘装置D2 从壳体D1内部向上取出、并对其进行清洁,从而方便用户进行清洁,提高手持吸尘器W的清洁效果。而当用户需要使用手持吸尘器W进行吸尘作业时,用户可以自行将除尘装置D2装回杯身D11内,然后将机盖D12盖合到杯身D11的顶部,即将机盖D12关闭,从而手持吸尘器W可以正常工作。
优选地,参照图20和图21,机盖D12的边缘包括相对设置的第一端和第二端(例如当机盖D12为圆形时,第一端和第二端位于机盖D12直径方向上的两侧),第一端与壳体D1铰接相连,第二端与壳体D1卡扣相连。由此,当将卡扣解扣后,用户可以提着机盖D12的第二端将机盖D12掀开,从而方便用户打开机盖D12,且避免了机盖D12完全取下时的丢失问题、以及机盖D12完全取下后难以再与壳体D1装配的问题。这里,需要说明的是,用于连接壳体D1和机盖D12的卡扣的结构为本领域技术人员所熟知,例如可以是电饭煲的开盖卡扣结构,从而这里不再赘述。当然,本发明不限于此,机盖D12还可以设计为可以完全从杯身D11上取下的结构,这里不再赘述。
进一步地,如图20和图21所示,机盖D12内具有连通腔,机盖D12的朝向杯身D11的一侧端面上具有将连通腔连通至除尘腔D102的进风口、和将连通腔连通至排气腔D101的出风口,机盖D12的一侧端面上设有可拆卸且封盖进风口的过滤件D121。由此,除尘腔D102内分离出的气流可以穿过过滤件D121和进风口进入到连通腔内,然后进入连通腔内的气流再通过出风口排出到排气腔D101内。由此,通过在机盖D12上设置连通腔和过滤件D121,可以进一步提高手持吸尘器W的清洁效果。而且,由于过滤件D121设在用户可直接拿取到的位置,且过滤件D121的用于过滤的一侧表面也朝外,从而用户可以一目了然地看出过滤件D121是否需要清洗,且在过滤件D121需要清洗时,用户可以很简单地将过滤件D121取下,然后清洗装回。
进一步地,参照图20和图21,杯身D11包括:安装架D111和集尘杯D112,除尘装置D2支撑在安装架D111的顶部,负压装置D3安装在安装架D111的底部,也就是说,安装架D111一方面可以起到托起除尘装置D2的作用,使得用户在向上提起除尘装置D2时可以将除尘装置D2从杯身D11中取出,安装架D111另一方面可以起到安装固定负压装置D3的作用,且使得负压装置D3位于除尘装置D2的下方,以避免影响负压装置D3向上取出。
如图20和图21所示,集尘杯D112为至少顶部敞开的壳体,且罩设在负压装置D3外,集尘杯D112与安装架D111可分离地相连。也就是说,集尘杯D112与安装架D111不是不可拆卸地固定在一起的。这样,当用户将集尘杯D112从安装架D111上取下时,负压装置D3还安装在安装架D111上位置不动,从而用户可以对取下的集尘杯D112进行倒灰、清洁作业,当用户清洁完集尘杯D112后,可以自下向上套入负压装置D3并将集尘杯D112连接到安装架D111上,此后集尘杯D112可以继续收集灰尘。
因此,根据本发明实施例的尘杯组件WD,由于机盖D12可打开,集尘杯D112、除尘装置D2、过滤件D121均为可拆取拿的部件,从而用户可选择地取下需要清洁的部件进行清洁,便于用户使用。
例如在本发明的一些可选示例中,集尘杯D112与安装架D111可以通过按钮卡钩结构可分离地相连,其中,按钮卡钩结构包括用于使集尘杯D112与安装架D111相连在一起的卡钩和用于对卡钩进行解锁的按钮,也就是说,当按钮被按下后,卡钩可以进行释放动作,以使集尘杯D112与安装架D111失去连接关系,从而可以将集尘杯D112从安装架D111上取下。其中,可以将两个部件锁定相连的卡钩和对卡钩进行解锁的按钮的具体结构和动作原理应为本领域技术人员所熟知,这里不再赘述。
例如在本发明的另一些可选示例中,集尘杯D112与安装架D111可以通过内外螺纹结构可分离地相连。例如,集尘杯D112的顶端的外周面上可以具有外螺纹,安装架D111为环形且内周面上具有内螺纹。由此,当转动集尘杯D112时,外螺纹可以旋入内螺纹内,使 得内螺纹与外螺纹螺纹配合,从而可以将集尘杯D112安装到安装架D111上。
在本发明的一些实施例中,参照图20和图21,安装架D111包括:筒形圈D1111、限位支撑部D1112和固定安装部D1113,集尘杯D112的顶端杯圈D1121与筒形圈D1111对接相连,也就是说,集尘杯D112的顶端杯圈D1121可以套接在筒形圈D1111外,集尘杯D112的顶端杯圈D1121还可以套接在筒形圈D1111内,筒形圈D1111的下端面还可以与壳体D1的上端面对接,以实现集尘杯D112与筒形圈D1111的可分离相连。由此,由于筒形圈D1111的结构形状可以很容易地与集尘杯D112的顶端杯圈D1121形状相匹配,从而可以很简单的将集尘杯D112与安装架D111装配相连,而且还可以很容易地确保筒形圈D1111与集尘杯D112之间的密封性,确保手持吸尘器W的整体工作性能。
参照图20和图21,固定安装部D1113设在筒形圈D1111内,也就是说,固定安装部D1113可以直接或者间接固定在筒形圈D1111内,且固定安装部D1113用于固定安装负压装置D3,也就是说,负压装置D3可以固定安装在固定安装部D1113上。限位支撑部D1112设在筒形圈D1111内,也就是说,限位支撑部D1112可以直接或者间接固定在筒形圈D1111内,限位支撑部D1112与除尘装置D2配合以限制除尘装置D2在除向上以外方向上的位移,也就是说,通过限位支撑部D1112与除尘装置D2的配合,除尘装置D2仅能向上移动、实现取出,而不能向下坠落或者在水平面内窜动。由此,通过设置限位支撑部D1112一方面可以起到安装除尘装置D2、使除尘装置D2正常工作的作用,另一方面确保除尘装置D2可以很方便地取出。这里,需要说明的是,本段中“设在筒形圈D1111内”指的是,沿筒形圈D1111轴向的投影位于筒形圈D1111的内环内部。
由此,由筒形圈D1111、限位支撑部D1112、固定安装部D1113组成的安装架D111的结构简单,仅通过一个安装架D111就能完成安装除尘装置D2、负压装置D3、以及集尘杯D112的多重作用,从而安装架D111的功能强大。
优选地,参照图20,安装架D111为一体成型件,也就是说,安装架D111为一个(除故意损坏)不可拆分的整体部件,例如筒形圈D1111、限位支撑部D1112、固定安装部D1113可以通过注塑的工艺加工为一个整体的部件。由此,安装架D111的结构更加简单、方便生产,且模块化强、便于装配,且尘杯组件WD的结构更加清晰、简洁,不易出现故障,可靠性高。
在本发明的实施例中,参照图20,杯身D11还可以包括吸嘴D113,吸嘴D113连通在手持吸尘器W的外界环境和除尘腔D102内以作为吸气口,将外界环境中的气流引入除尘腔D102,吸嘴D113固定在安装架D111上,或者吸嘴D113与安装架D111一体成型(也就是说,除故意损坏、安装架D111与吸嘴D113不可拆分,即安装架D111与吸嘴D113为一个整体部件)。由此,安装架D111的功能更加强大、模块化更强,使得尘杯组件WD的结构更加简洁、清晰,不易出现故障,可靠性高。
另外,在本发明的实施例中,参照图20,本文所述的手柄壳E1的至少部分也与安装架D111为一体成型件(也就是说,除故意损坏、安装架D111与手柄壳E1的至少部分不可拆分,即安装架D111与手柄壳E1的至少部分为一个整体部件)。由此,安装架D111的功能更加强大、模块化更强,使得尘杯组件WD的结构更加简洁、清晰,不易出现故障,可靠性高。
优选地,参照图20,吸嘴D113、手柄壳E1的至少部分、与安装架D111为一体成型件(也就是说,除故意损坏、安装架D111与手柄壳E1的至少部分与吸嘴D113不可拆分,即安装架D111与手柄壳E1的至少部分与吸嘴D113为一个整体部件)。由此,安装架D111的功能更加强大、模块化更强,使得尘杯组件WD的结构更加简洁、清晰,不易出现故障,可靠性高。
在本发明的实施例中,除尘装置D2上具有沿上下方向贯通的限位孔D210和底部敞开的支撑槽D211,支撑槽D211包括设在限位孔D210径向两侧的两个子支撑槽D2111。限 位支撑部D1112包括:限位柱Da和支撑梁Db,限位柱Da设在筒形圈D1111内且与限位孔D210插接配合,支撑梁Db包括分别设在限位柱Da径向两侧的两个子支撑梁Db1,两个子支撑梁Db1对应地设在两个子支撑槽D2111内且支撑对应的子支撑槽D2111的顶壁。这里,需要说明的是,由于支撑槽D211的底部敞开,从而支撑槽D211存在顶壁,而当支撑槽D211的顶壁敞开时,支撑槽D211可以存在底壁。
由此,通过限位孔D210与限位柱Da的插接配合,可以有效地避免除尘装置D2相对安装架D111在水平面内窜动,通过支撑梁Db对支撑槽D211的支撑,安装架D111可以有效地托起除尘装置D2避免除尘装置D2下落,且可以有效地避免除尘装置D2相对安装架D111在水平面内转动。而且,除尘装置D2和限位支撑部D1112的结构简单,便于加工、便于装配,且限位支撑部D1112对除尘装置D2的支撑效果好、限位效果好。
这里,需要说明的是,“限位柱Da与限位孔D210插接配合”指的是,限位柱Da与限位孔D210的形状相匹配,当限位柱Da同轴地插配到限位孔D210内后,限位柱Da与限位孔D210间隙配合且间隙均匀。优选地,限位柱Da的横截面为圆形,但是不限于此,限位柱Da的横截面也可以为多边形或者非规则形状,其中,当限位柱Da的横截面为圆形时,限位柱Da的径向指的是其直径方向,而当限位柱Da的横截面为非圆形时,限位柱Da的径向指的是其横截面的长度方向。
在本发明的一个可选实施例中,参照图20和图21,每个子支撑梁Db1上均具有一个向下延伸的拼板Dc,除尘装置D2包括:分裂型滤筒D22(分裂型滤筒D22指的是,横截面为非闭合环、或者说间断环的过滤筒)和滤筒盖板D21,分裂型滤筒D22包括分别设在支撑槽D211两侧的两个弧形过滤件D221,两个拼板Dc分别连接在两个弧形过滤件D221的彼此邻近的侧边之间以与两个弧形过滤件D221组成连续型滤筒(连续型滤筒指的是:横截面为闭合环的过滤筒),滤筒盖板D21盖设在连续型滤筒的顶部,且限位孔D210形成在滤筒盖板D21的中央,支撑槽D211形成在滤筒盖板D21的底壁上。由此,除尘装置D2的结构简单,方便与安装架D111进行装配。而且,通过形成连续型滤筒,从而可以在连续型滤筒的外周面和杯身D11的内周面之间可以进行第一级旋风分离,从而达到良好的除尘效果。
可选地,除尘装置D2还包括:旋风筒组件,旋风筒组件设在分裂型滤筒D22内,旋风筒组件为两个且位于支撑槽D211的两侧,每个旋风筒组件均与对应的弧形过滤件D221相连且包括沿分裂型滤筒D22的周向排布的多个旋风筒,滤筒盖板D21上具有对应地伸入到每个旋风筒内的出风管D212,其中,每个旋风筒均构造为底部渐缩且侧壁上具有切向入口的锥形筒。由此,在连续型滤筒外一次旋风分离出的气流可以通过弧形过滤件D221上的过滤孔D220进入到连续型滤筒内部,然后再进入到多个旋风筒内进行二次旋风分离,二次旋风分离出的气流可以通过出风管D212向上输出,从而可以进一步提高尘杯组件WD的除尘效果。优选地,前文所述的机盖D12上的进风口可以为多个且与多个出风管D212的上端一一正对,由此,方便除尘腔D102向连通腔输入气体,且吸尘效率高。
优选地,限位柱Da为空心柱体且其内部限定出上述排气腔D101,排气腔D101的底部与负压装置D3连通,例如,固定安装部D1113可以为与限位柱Da上下对接且连通的罩体,负压装置D3设在罩体内部。由此,当负压装置D3启动时,罩体内可以产生负压,与罩体连通的限位柱Da内也产生负压,同时与限位柱Da内的排气腔D101连通的机盖D12内的连通腔内也产生负压,同时与连通腔连通的除尘腔D102内也产生负压,从而除尘腔D102可以通过吸嘴D113从外界环境中吸入气流。
下面,参照图20和图21,描述根据本发明实施例的手柄组件WE。
参照图20和图21,供电装置E2设在手柄壳E1内的顶部或手柄壳E1外的顶部,例如,供电装置E2可以是嵌设在手柄壳体D1内的电池组件,供电装置E2还可以是与手柄壳E1可分离的电池包。由此,通过将供电装置E2设在手柄壳E1的顶部,从而可以优化手持吸 尘器W的整体重心,使用户可以更加省力地持握手持吸尘器W。

优选地,参照图20和图21,持握部E11的上端与上臂部E12的底部中央相连、下端朝向远离壳体D1的方向延伸,也就是说,沿着从上到下的方向,持握部E11朝向远离壳体D1的方向倾斜延伸,从而可以使得用户更加省力地持握持握部E11,且用户可以更加轻便地调整手持吸尘器W的工作角度。另外,通过将持握部E11的上端连接在上臂部E12的底部中央,从而可以提高持握部E11的支撑可靠性,减小持握部E11的受力。可选地,下臂部E13沿着从壳体D1到持握部E11的方向倾斜向上延伸,由此,可以提高用户的握手空间,方便用户抓握持握部E11。
在本发明的一个可选示例中,参照图20,壳体D1上具有接电口,供电装置E2安装在上臂部E12外的顶部且与接电口电性插接,由此,方便取下供电装置E2进行充电。这里,可以理解的是,接电口可以通过贯穿手柄壳E1和壳体D1的导线与负压装置D3电性相连,但不限于此。
优选地,持握部E11可以包括握手内壳和握手外壳,上臂部E12可以包括上臂上壳和上臂下壳,下臂部E13可以包括下臂下壳和下臂上壳,其中,握手内壳、上臂下壳、下臂上壳可以与壳体D1为一体成型件,握手外壳可以可拆卸地安装在握手内壳的外侧,上臂上壳可以可拆卸地安装在上臂下壳的顶部,下臂下壳可以可拆卸地安装在下臂上壳的底部。

优选地,参照图20和图21,壳体D1的外表面为圆柱形,持握部E11的中心线(即沿持握部E11长度方向延伸的中心线)、上臂部E12的中心线(即沿上臂部E12长度方向延伸的中心线)、下臂部E13的中心线(即沿下臂部E13长度方向延伸的中心线)和壳体D1的轴线位于同一平面内。由此,可以更加有效地优化手持吸尘器W整机的重心,使用户可以更加省力地持握手持吸尘器W。
下面,参照附图20和图21,简要描述根据本发明实施例的手持吸尘器W的工作原理。
当负压装置D3(例如由电机和风扇组成)启动时,除尘腔D102通过吸嘴D113从外界环境中吸入尘气,尘气进入杯身D11内后、在连续型滤筒的外周面和杯身D11的内周面之间进行一次旋风分离,一次旋风分离出的尘质落入集尘杯D112内的底部、一次旋风分离出的气流可以通过连续型滤筒上的过滤孔D220进入到连续型滤筒内,并通过每个旋风筒侧壁上的切向入口进入到多个旋风筒内进行二次旋风分离,在多个旋风筒内旋风分离出的尘质通过旋风筒底部的出口向下落入集尘杯D112内的底部、而在多个旋风筒内二次旋风分离出的气流可以向上、并经过滤筒盖板D21上的出风管D212、和机盖D12上的过滤件D121和进风口进入到连通腔内,之后连通腔内的气流通过机盖D12上的出风口排出到排气腔D101内,然后气流再流经负压装置D3,之后通过壳体D1上的排气口送出。
下面,简要描述根据本发明实施例的手持吸尘器W的有益效果。
1、相关技术中的手持吸尘器,供电装置和负压装置均设在手柄内,且供电装置通常设 置在手柄的底部,从而致使手柄的体积大、重量大,不但不便于用户手持,而且手持费力、舒适度不高。
然而,根据本发明实施例的手持吸尘器W,通过将供电装置E2设置在手柄壳E1的顶部,同时将负压装置D3设在集尘杯D112内,从而有效地改善了手持吸尘器W的重心分布,即平衡了手持吸尘器W整体的重心位置,进而提高了用户持握手持吸尘器W的舒适度,使得用户可以更加省力、轻便地使用手持吸尘器W,愉悦了用户体验。
2、相关技术中的手持吸尘器,除尘装置均固定在机体内部,用户不能自行将除尘装置拆卸出来进行清洗,这样,残留在除尘装置内的灰尘就很容易引发细菌滋生、并产生异味,从而会对下一次的使用造成二次污染,削弱整体的清洁效果。
然而,根据本发明实施例的手持吸尘器W,由于机盖D12可以很方便地打开,且除尘装置D2可以从集尘杯D112内部取出,从而方便用户对除尘装置D2进行清洁,避免壳体D1内部残留灰尘,避免细菌滋生和产生异味等问题,提高了手持吸尘器W整体的清洁效果。
实施例三、
下面,参照附图22-33,描述根据本发明实施例的手持吸尘器V。
如图22、图28和图30所示,手持吸尘器V包括尘杯组件VB和手柄组件VC,其中,尘杯组件VB包括壳体B1、除尘装置B2和负压装置B3,壳体B1上具有吸气口和排气口,负压装置B3设置在壳体B1内部且用于将环境中的尘气从吸气口吸入壳体B1内部,除尘装置B2设置在壳体B1内部且用于对吸入到壳体B1内的气流进行尘气分离,分离出的气流可以在负压装置B3的作用下从排气口排出到壳体B1外,而分离出的尘质可以存留在壳体B1内部。这里,需要说明的是,手持吸尘器指的是,用户可以通过手持动作将整机拿起的吸尘器,即区别于现有技术中整机需要在支撑面上推动的吸尘器。
参照图22和图30,手柄组件VC安装在尘杯组件VB上、例如可以安装在壳体B1上且用于手持,也就是说,用户可以通过持握手柄组件VC来拿起尘杯组件VB,从而进行清洁作业。另外,可选地,手柄组件VC可以包括手柄壳C1和供电装置C2,其中,手柄壳C1设在壳体B1上且用于手持,供电装置C2安装在手柄壳C1上且与负压装置B3电性相连,由此,供电装置C2可以向负压装置B3提供电能,而且,由于供电装置C2安装在手柄组件VC的手柄壳C1上,负压装置B3安装在尘杯组件VB的壳体B1内,从而可以优化手持吸尘器V的整体重心,使用户可以更加轻松省力地持握手持吸尘器V。
下面,描述根据本发明实施例的尘杯组件VB。
参照图30,壳体B1内具有中心腔B101、除尘腔B102和集尘腔B103,其中,中心腔B101为立柱形且包括上下连通的排气腔B1011和安装腔B1012,除尘腔B102的横截面为闭合环形且环绕排气腔B1011一周,集尘腔B103位于除尘腔B102的下方且横截面为非闭合环形且围绕安装腔B1012不足一周。这里,需要说明的是,中心腔B101的横截面不限于圆形、多边形等规则形状,且中心腔B101每个横截面的尺寸也可以不一致,也就是说,中心腔B101的形状不限于等截面的规则柱体,另外,除尘腔B102的横截面也不限于闭合圆环形、闭合多边环形,例如还可以是不规则的环形,同理,集尘腔B103的横截面也不限于开口圆环形、开口多边环形,例如还可以是不规则的开口环形。
参照图30和图33,负压装置B3的至少多半部分设于安装腔B1012内,也就是说,负压装置B3的设在安装腔B1012内的部分的体积占负压装置B3总体积的一半以上。由此,通过将集尘腔B103设置为横截面为非闭合环形的开环形状,从而可以降低集尘腔B103的占用空间,以变相提高安装腔B1012的占用空间,进而方便负压装置B3的安装。优选地,排气腔B1011的下部为扩容段,也就是说,排气腔B1011的下部的横向容积大于排气腔B1011的上部的横向容积,例如排气腔B1011的下部的横截面积可以逐渐增大,此时,负压装置B3的上端部可以伸入到扩容段内,从而提高结构的紧凑型,降低安装腔B1012的 高度。当然,本发明不限于此,负压装置B3还可以完全设置在安装腔B1012内。
当然,本发明不限于此,在本发明的其他实施例中,壳体B1内还可以不具有排气腔B1011,此时除尘腔B102可以为柱形空腔且叠设在集尘腔B103和安装腔B1012的上方,此时,安装腔B1012可以直接与除尘腔B102连通。另外,参照图30,当壳体B1内具有排气腔B1011时,排气腔B1011可以通过连通腔B105等其他途径与除尘腔B102连通,从而负压装置B3可以通过排气腔B1011和连通腔B105与除尘腔B102连通,以用于将环境中的尘气吸入除尘腔B102内。
参照图22和图30,壳体B1可以包括机壳B11和尘杯B12,其中,中心腔B101和除尘腔B102均形成在机壳B11内且分别用于安装负压装置B3和除尘装置B2,集尘腔B103形成在尘杯B12内且用于盛装由除尘装置B2分离出的尘质,机壳B11与尘杯B12可拆组地相连,从而当需要应用手持吸尘器V进行清洁时,用户可以自行将机壳B11安装在尘杯B12上以收集灰尘,而不需要应用手持吸尘器V进行清洁时,例如需要倒出尘杯B12内的灰尘,或者需要对手持吸尘器V进行清洁或维护时,用户可以将尘杯B12从机壳B11上取下。
例如在图23、图30和图31所示的示例中,机壳B11通过快拆组件与尘杯B12可拆卸地相连,集尘腔B103位于安装腔B1012的前侧(即后文所述的杯壳B122设在基座B121顶部的前侧),快拆组件包括设在尘杯B12前侧顶部的第一组件B141和设在尘杯B12后侧底部的第二组件B142。由此,快拆组件可以将尘杯B12的前侧顶部和后侧底部与机壳B11分别可拆卸地相连,从而可以有效地提高尘杯B12与机壳B11的连接可靠性、稳定性,且方便机壳B11与尘杯B12的拆装。
可选地,参照图22和图23,第一组件B141包括:卡板B1411和卡片B1412,其中,卡板B1411设在机壳B11的前侧底部且向下延伸,卡板B1411上具有卡孔B14110,卡片B1412设在尘杯B12的前侧顶部且向前伸入卡孔B14110内以限制尘杯B12与机壳B11在除前后方向以外的方向上分离,也就是说,通过卡板B1411与卡片B1412的配合,尘杯B12与机壳B11只能在前后方向上分离,而在其他方向均不能分离。由此,第一组件B141的结构简单,便于加工和拆装,且限位可靠性高。
可选地,参照图22、图30和图31,第二组件B142包括:第一卡钩B1421、第二卡钩B1422、移动锁扣B1423和解锁按钮B1424,其中,第一卡钩B1421设在机壳B11的后侧底部且前端向下弯曲以限定出钩槽,第二卡钩B1422设在尘杯B12的后侧底部且后端向上弯曲以伸入到钩槽内以限制尘杯B12与机壳B11在前后方向上分离,也就是说,通过第一卡钩B1421和第二卡钩B1422的配合,尘杯B12与机壳B11不能在前后方向上分离。由此,第二组件B142的结构简单,便于加工和拆装,且限位可靠性高。另外,通过第一组件B141和第二组件B142的组合限位,尘杯B12与机壳B11在任何方向上都不能分离,从而提高壳体B1的组装可靠性。
可选地,参照图22、图30和图31,第二组件B142还可以包括移动锁扣B1423和解锁按钮B1424,其中,移动锁扣B1423可前后移动地设在机壳B11的后侧底部且前端止抵在第二卡钩B1422的底部以限制第二卡钩B1422向下移出钩槽,从而移动锁扣B1423可以防止第二卡钩B1422向下移动,以确保第二卡钩B1422与第一卡钩B1421的限位可靠性,其中,解锁按钮B1424可按动地设在机壳B11上且与移动锁扣B1423配合,解锁按钮B1424构造成在被按下时使移动锁扣B1423后移以解除对第二卡钩B1422的限位,也就是说,解锁按钮B1424被按下时,解锁按钮B1424可以驱动移动锁扣B1423后移,此时移动锁扣B1423的前端不再止抵在第二卡钩B1422的底部,从而第二卡钩B1422可以向下移出钩槽,以解除限位。这里,可以理解的是,通过解锁按钮B1424的下移,使移动锁扣B1423解锁的方式有很多,例如可以通过图22中所示的楔形块和楔形槽的配合,这里不再赘述。
如图22-图25所示,尘杯B12可以包括:基座B121和杯壳B122,杯壳B122的横截 面为具有开口的非闭合环形以使杯壳B122内限定出横截面为非闭合环形的集尘腔B103,杯壳B122设在基座B121的顶部且杯壳B122的内环壁面B1221与基座B121的顶壁之间限定出位于集尘腔B103外的安装空间B107,安装空间B107的顶部直接敞开、侧部由开口敞开。由此,机壳B11的包容负压装置B3的部分可以通过安装空间B107的敞开处安装于安装空间B107,从而可以极其方便机壳B11及负压装置B3的拆装,提高拆装效率,方便用户使用。
优选地,参照图23和图24,基座B121为扁圆柱形(即直径大于轴高的圆柱形),杯壳B122的外环壁面B1222为由基座B121边缘的一段弧线竖直拉伸而成的弧形面板。也就是说,杯壳B122的外环壁面B1222落在基座B121的外周壁面所在的圆柱面上。由此,基座B121与杯壳B122的连接处可以光滑过渡,从而提高尘杯B12整体的美观性。优选地,上述一段弧线的圆心角为180°~200°,也就是说,杯壳B122的外环壁面B1222的圆心角为180°~200°,从而可以确保集尘腔B103的尺寸足够大,提高尘杯B12的灰尘收集量。另外,杯壳B122的内环壁面B1221也可以加工为由弧形曲线竖直拉伸而成的弧形面板,从而方便加工且加工工艺好。
参照图22、图23和图30,机壳B11可以包括:上机身部B111和下机身部B112,上机身部B111设在下机身部B112的顶部且其内部形成有排气腔B1011和除尘腔B102,下机身部B112设在上机身部B111的底部且其内部形成有安装腔B1012,其中下机身部B112由安装空间B107的敞开处安装于安装空间B107,上机身部B111支撑在杯壳B122的顶部。由此,机壳B11的结构简单且与尘杯B12的外形相匹配,从而不但便于机壳B11与尘杯B12的拆装,而且壳体B1的整体结构可靠性高。
参照图23和图32,下机身部B112可以包括:保护壳板B1121和外观壳板B1122,其中,保护壳板B1121邻近内环壁面B1221设置,外观壳板B1122位于保护壳板B1121的远离内环壁面B1221的一侧且与保护壳板B1121之间限定出上述安装腔B1012,由此,下机身部B112的结构简单、便于加工。优选地,保护壳板B1121的形状与内环壁面B1221的形状相匹配,也就是说,保护壳板B1121与内环壁面B1221之间的距离处处相等,从而可以提高空间利用率且可以改善安装干涉等问题。优选地,保护壳板B1121的两侧边缘分别与杯壳B122在环长方向上的两侧边缘对应相接,由此,可以提高手持吸尘器V整体的美观效果。
例如在图22、图23、图24和图32所示的示例中,杯壳B122设在基座B121的前部且横截面为向前凸出的圆环形,保护壳板B1121为向前凸出的弧形面板,外观壳板B1122为向后凸出的弧形面板,保护壳板B1121的左右两端分别与外观壳板B1122的内表面相连以与外观壳板B1122之间限定出安装腔B1012,外观壳板B1122的左端向左前方延伸且与杯壳B122的左端相接,外观壳板B1122的右端向右前方延伸且与杯壳B122的右端相接。由此,下机身部B112的结构简单、便于加工。
优选地,参照图22、图23、图30和图32,安装腔B1012内还可以设有:排风过滤装置B4,排风过滤装置B4位于负压装置B3与外观壳板B1122之间且与外观壳板B1122之间限定出排风空间B106,其中,基座B121支撑在下机身部B112的底部且避让排风空间B106的底部。由此,由负压装置B3吸入到安装腔B1012内的气流可以再通过排风过滤装置B4的过滤,然后再通过排风空间B106的底部排出到壳体B1外,从而可以提高手持吸尘器V整体的清洁效果。而且,由于基座B121支撑在下机身部B112的底部且可以有效地避免负压装置B3和排风过滤装置B4向下脱落的问题,而且可以避免机壳B11将全部的压力都作用到杯壳B122上引起杯壳B122被压坏的问题。另外,机壳B11还可以包括安装在保护壳板B1121底部的底盖,进一步避免负压装置B3向下脱落。
优选地,参照图23和图32,保护壳板B1121和/或外观壳板B1122上具有沿上下方向延伸的滑槽B11210,排风过滤装置B4上具有弹性滑片B41,弹性滑片B41可滑移地配合 在滑槽B11210内且弹性滑片B41与滑槽B11210弹性过盈配合,由此,可以通过弹性滑片B41与滑槽B11210的弹性过盈滑移配合,实现排风过滤装置B4与安装腔B1012的快速拆装,方便用户更换清洁排风过滤装置B4。例如在图23和图32所示的示例中,保护壳板B1121的左右两侧分别具有一个滑槽B11210,排风过滤装置B4的左右两侧分别具有一个弹性滑片B41,左侧的弹性滑片B41可滑移地配合在左侧的滑槽B11210内,右侧的弹性滑片B41可滑移地配合在右侧的滑槽B11210内。由此,配合滑移的稳定性更好、卡位可靠性更好。
参照图30和图32,安装腔B1012内还可以设有:隔离网B5,隔离网B5拦截在负压装置B3与排风过滤装置B4之间。由此,可以进一步提高负压装置B3的工作可靠性避免排风过滤装置B4被卷入负压装置B3内等问题。
参照图28和图30,上机身部B111可以包括:筒形壳B1111和排风管B1112,排风管B1112设在筒形壳B1111内且与筒形壳B1111之间限定出除尘腔B102,排风管B1112的底部贯通筒形壳B1111的底壁且排风管B1112内限定出与安装腔B1012连通的排气腔B1011,此时,除尘装置B2可以套设在排风管B1112上且位于除尘腔B102内,负压装置B3的上端部可以伸入到排风管B1112内,优选地,排风管B1112的下部为扩容管段B11120,也就是说,排风管B1112下部的横向容积大于排风管B1112上部的横向容积,例如排风管B1112的下部的横截面积可以逐渐增大,从而可以提高壳体B1整体的紧凑性,降低壳体B1的整体高度。
在本发明的一些实施例中,参照图22、图28和图29,壳体B1还可以包括:可开关地设在机壳B11顶部的机盖B13,也就是说,机盖B13可以设在筒形壳B1111的顶部,此时,除尘装置B2可取出地设在除尘腔B102内且位于负压装置B3的上方。由此,当需要清洁手持吸尘器V时,用户可以自行将机盖B13打开并将位于上方的除尘装置B2从机壳B11内部取出进行清洁,从而方便用户清洁,提高手持吸尘器V的清洁效果。而当用户需要使用手持吸尘器V进行吸尘作业时,用户可以自行将除尘装置B2装回机壳B11内,然后将机盖B13盖合到机壳B11的顶部,即将机壳B11关闭,从而手持吸尘器V可以正常工作。
可选地,机盖B13的边缘包括相对设置的第一端和第二端(例如当机盖B13为圆形时,第一端和第二端位于机盖B13直径方向上的两侧),第一端与机壳B11铰接相连,第二端与机壳B11卡扣相连。由此,当将卡扣解扣后,用户可以提着机盖B13的第二端将机盖B13掀开,从而方便用户打开机盖B13,且避免了机盖B13完全取下时的丢失问题、以及机壳B11完全取下后难以再与机壳B11装配的问题。这里,需要说明的是,用于连接机壳B11和机盖B13的卡扣的结构为本领域技术人员所熟知,例如可以是电饭煲的开盖卡扣结构,从而这里不再赘述。当然,本发明不限于此,机盖B13还可以设计为可以完全从机壳B11上取下的结构,这里不再赘述。
可选地,参照图29和图30,机盖B13内可以具有连通腔B105,机盖B13的朝向上机身部B111的一侧端面上具有将连通腔B105连通至除尘腔B102的进风口、和将连通腔B105连通至中心腔B101的出风口B1301,且机盖B13的一侧端面上设有可拆卸且封盖进风口的过滤件B131。由此,除尘腔B102内分离出的气流可以穿过过滤件B131和进风口进入到连通腔B105内,然后进入连通腔B105内的气流再通过出风口B1301排出到中心腔B101内。由此,通过在机盖B13上设置连通腔B105和过滤件B131,可以进一步提高手持吸尘器V的清洁效果。而且,由于过滤件B131设在用户可直接拿取到的位置,且过滤件B131的用于过滤的一侧表面也朝外,从而用户可以一目了然地看出过滤件B131是否需要清洗,且在过滤件B131需要清洗时,用户可以很简单地将过滤件B131取下,然后清洗装回。
在本发明的一些实施例中,参照图28、图29和图30,除尘装置B2可以包括旋风分离件B21和盖设在旋风分离件B21上的端盖B22,其中,旋风分离件B21可以包括:过滤筒B211和多个旋风筒B212。过滤筒B211设在除尘腔B102内将除尘腔B102划分为位于过 滤筒B211内外两侧的第二旋风腔B1022和第一旋风腔B1021,其中,当上机身部B111内具有排风管B1112时,过滤筒B211设在除尘腔B102内且空套排风管B1112,此时,过滤筒B211与排风管B1112之间限定出第二旋风腔B1022,过滤筒B211与筒形壳B1111之间限定出第一旋风腔B1021。
参照图25、图29、图30和图33,多个旋风筒B212均设在第二旋风腔B1022内且沿过滤筒B211的周向依次排布且位于杯壳B122顶部的正上方,或者说,多个旋风筒B212围绕排气腔B1011(或排风管B1112)设置且位于集尘腔B103的正上方,从而多个旋风筒B212的中心连线也为具有开口的非闭合环线,由此,可以确保每个旋风筒B212内分离出的尘质准确无误地排入到集尘腔B103内,而且可以降低成本。可选地,每个旋风筒B212均可以固定在过滤筒B211的内周壁上,从而使得旋风过滤件B131为一个整体件,从而方便拆装和加工。优选地,每个旋风筒B212均可以构造成底部缩口的锥形筒,以避免与排风管B1112底部的扩容管段B11120干涉,提高结构的紧凑性。
参照图28、图29和图30,过滤筒B211上的侧壁上具有过滤孔B2110,例如过滤筒B211可以包括具有插槽的过滤筒本体B2111和插设在插槽处的过滤网B2112,每个旋风筒B212的侧壁上均具有切向入口B2120,筒形壳B1111上具有吸气管B1113,吸气管B1113与筒形壳B1111的连接处具有导向件,导向件用于将气流沿切向的导入第一旋风腔B1021内,从而进入第一旋风腔B1021内的气流可以沿周向运动,此时气流中的尘质可以通过离心力被甩出,而气流中分离出的气体可以通过过滤筒B211上的过滤孔B2110进入到第二旋风腔B1022内,进入到第二旋风腔B1022内的气流可以通过切向入口B2120进入旋风筒B212内并在旋风筒B212内沿周向运动,此时气流中的尘质可以通过离心力被甩出并通过旋风筒B212的底部排出,而气流中分离出的气体可以通过旋风筒B212顶部向上排出,从而实现旋风分离的除尘作业。这里,需要说明的是,本文中所述的气体当作广义理解,即包括含有尘质细颗粒的非纯净气体。
可选地,参照图29、图30和图31,端盖B22包括盖设在旋风分离件B21上的盖板B221和穿插在盖板B221上的多个出风管B222,多个出风管B222的下端分别对应地伸入到多个旋风筒B212内、上端分别与多个机盖B13上的多个进风口正对,以将从旋风筒B212内分离出的气流引入连通腔B105。由此,通过设置端盖B22,可以将旋风筒B212内分离出的气体简单、有效、且可靠地引出到连通腔B105内,且通过设置端盖B22,可以确保除尘装置B2更加的模块化,整体性更强。
当然,本发明不限于此,除尘装置B2还可以不包括旋风分离件B21和端盖B22,此时,除尘装置B2可以为简单的过滤网,而且,旋风分离件B21还可以不包括过滤筒B211等,也就是说,除尘装置B2的具体结构可以根据实际生产要求具体配置。
参照图25-图27、图30和图33,杯壳B122内设有分腔壁B123,分腔壁B123设在内环壁面B1221与外环壁面B1222之间且将集尘腔B103划分为隔离在分腔壁B123两侧的第一集尘腔B1031和第二集尘腔B1032,也就是说,通过分腔壁B123的隔离作用,第一集尘腔B1031和第二集尘腔B1032互不连通,从而第一集尘腔B1031内的灰尘不会倒流到第二集尘腔B1032内,以避免干涉本文所述的第二级旋风分离作业。
参照图27,第一集尘腔B1031的顶端敞开为第一集尘腔B1031的入口、第二集尘腔B1032的顶端敞开为第二集尘腔B1032的入口,第一集尘腔B1031的底端敞开为第一集尘腔B1031的出口、第二集尘腔B1032的底端敞开为第二集尘腔B1032的出口B1230。
第一集尘腔B1031位于第一旋风腔B1021的正下方且第一集尘腔B1031的入口与第一旋风腔B1021连通,第二集尘腔B1032位于第二旋风腔B1022的正下方且第二集尘腔B1032的入口与多个旋风筒B212连通。由此,从第一旋风腔B1021分离出的尘质可以准确地向下排入到第一集尘腔B1031内,从旋风筒B212分离出的尘质可以准确地向下排入到第二集尘腔B1032内,以有效地改善集尘腔B103内尘质向除尘腔B102内倒流的问题,提高清 洁效果和清洁效率。
可选地,第二集尘腔B1032的底壁为中央高且两端低的斜壁,斜壁的两端敞开为第二集尘腔B1032的出口B1230。由此,落入到第二集尘腔B1032内的灰尘可以自上向下沿着第二集尘腔B1032的底壁向下滑落到第二集尘腔B1032底部的两侧的出口B1230处,从而可以有效地避免第二集尘腔B1032内的灰尘扬起的问题。
可选地,分腔壁B123包括:立壁B1231和卧壁B1232,立壁B1231立设于内环壁面B1221与外环壁面B1222之间,参照图26和图27,立壁B1231可以为竖直设置的前凸弧形板,立壁B1231的顶端与集尘腔B103的顶端平齐,卧壁B1232连接在立壁B1231的底端与内环壁面B1221之间,卧壁B1232、立壁B1231和内环壁面B1221之间限定出第二集尘腔B1032。由此,分腔壁B123的结构简单,便于加工。
参照图24和图25,尘杯B12还可以包括:杯盖B124,杯盖B124设在杯壳B122的顶部且封盖集尘腔B103,杯盖B124上具有与集尘腔B103连通的进尘口B1240,进尘口B1240包括连通在第一集尘腔B1031和第一旋风腔B1021之间的第一进尘口B1241、和连通在第二集尘腔B1032和多个旋风筒B212之间的第二进尘口B1242,每个旋风筒B212的下端均穿过筒形壳B1111的底壁且插配到相应的第二进尘口B1242内。由此,通过设置杯盖B124,一方面避免集尘腔B103内的尘质流入环境中,另一方面可以起到定位旋风筒B212的作用,提高旋风分离件B21的安装可靠性。
例如在图24和图25所示的示例中,杯盖B124可以为具有开口的非闭合环形以与集尘腔B103的顶部形状相匹配,其中,第一进尘口B1241可以为一个且位于杯盖B124的外环部侧,第二进尘口B1242可以为六个且位于杯盖B124的内环部侧且在杯盖B124的长度方向上间隔开,每个第二进尘口B1242的形状、尺寸均与相应的旋风筒B212的下端相匹配,从而当将多个旋风筒B212的下端插入多个第二进尘口B1242内之后,可以避免旋风分离件B21在筒形壳B1111内晃动,提高旋风分离件B21的工作可靠性。
这里,需要说明的是,当除尘腔B102不分为第一旋风腔B1021和第二旋风腔B1022时,尘杯B12内可以不设置分腔壁B123,也就是说,集尘腔B103无需分成第一集尘腔B1031和第二集尘腔B1032,此时,杯盖B124上仅需加工进尘口B1240即可,无需加工第一进尘口B1241和第二进尘口B1242。
参照图24-图27、图25和图30,基座B121可以包括基座本体B1211和基座底盖B1212,基座底盖B1212可开关地连接在基座本体B1211的底部以与基座本体B1211之间限定出缓存腔B104,基座本体B1211的顶壁上具有连通孔,外环壁面B1222的底端边缘与连通孔的边缘对接以使第一集尘腔B1031连通至缓存腔B104,内环壁面B1221和分腔壁B123的底端边缘插配到连通孔内且止抵在基座底盖B1212上以使第二集尘腔B1032与第一集尘腔B1031和缓存腔B104隔离开。
由此,当基座底盖B1212位于关闭位置时,基座底盖B1212与基座本体B1211之间限定出缓存腔B104,此时,第一集尘腔B103内的尘质可以排出到缓存腔B104内,并积存与缓存腔B104内,第二集尘腔B1032内的尘质可以积存在第二集尘腔B1032的底部,而当基座底盖B1212处于打开位置时,基座底盖B1212将缓存腔B104的底部和第二集尘腔B1032的底部打开,从而缓存腔B104内的灰尘可以向下排出,第二集尘腔B1032内的灰尘可以向下排出。
由此,参照图24和图25,通过设置基座B121可以提高尘杯B12的总容量,且通过将基座底盖B1212设置成可开关的形式,可以方便尘杯B12倒灰。另外,可以理解的是,基座底盖B1212与基座本体B1211为可打开连接的方式可以有多种,例如基座本体B1211的一端可以与基座底盖B1212的一端铰接,基座本体B1211的另一端与基座底盖B1212的的另一端卡扣连接,从而当将卡扣解扣时,基座本体B1211的另一端可以在重力的作用下向下翻转以实现打开动作。
下面,描述根据本发明实施例的手柄组件VC。
参照图22和图30,供电装置C2设在手柄壳C1内的顶部或手柄壳C1外的顶部,例如,供电装置C2可以是嵌设在手柄壳C1体B1内的电池组件,供电装置C2还可以是与手柄壳C1可分离的电池包。由此,通过将供电装置C2设在手柄壳C1的顶部,从而可以优化手持吸尘器V的整体重心,使用户可以更加省力地持握手持吸尘器V。
可选地,参照图22和图30,手柄壳C1包括:持握部C11、上臂部C12和下臂部C13,其中,持握部C11立式设置且与机壳B11间隔开,上臂部C12连接在持握部C11的上端与机壳B11之间,下臂部C13连接在持握部C11的下端与机壳B11之间,其中,供电装置C2设在上臂部C12内或上臂部C12外的顶部,从而可以确保供电装置C2位于手柄壳C1的顶部。由此,通过设置上臂部C12和下臂部C13可以将持握部C11可靠地安装在机壳B11上,而且通过设置持握部C11,用户可以抓牢手柄组件VC。当然,本发明不限于此,在本发明的其他实施例中,手柄壳C1还可以形成为其他形状,例如手柄壳C1还可以不包括下臂部C13等,这里不再赘述。
优选地,参照图22和图30,持握部C11的上端与上臂部C12的底部中央相连、下端朝向远离机壳B11的方向延伸,也就是说,沿着从上到下的方向,持握部C11朝向远离机壳B11的方向倾斜延伸,从而可以使得用户更加省力地持握持握部C11,且用户可以更加轻便地调整手持吸尘器V的工作角度。另外,通过将持握部C11的上端连接在上臂部C12的底部中央,从而可以提高持握部C11的支撑可靠性,减小持握部C11的受力。可选地,下臂部C13沿着从机壳B11到持握部C11的方向倾斜向上延伸,由此,可以提高用户的握手空间,方便用户抓握持握部C11。
在本发明的一个可选示例中,参照图22和图30,上臂部C12为水平设置的长方形壳体B1,供电装置C2设在上臂部C12内。由此,上臂部C12的结构简单,便于加工且便于安装供电装置C2,且可以提高供电装置C2的安装牢靠性。在本发明的另一个可选示例中(图未示出该示例),机壳B11上具有接电口,供电装置C2安装在上臂部C12外的顶部且与接电口电性插接,由此,方便取下供电装置C2进行充电。
优选地,上臂部C12和下臂部C13的至少部分与机壳B11为一体成型件,也就是说,上臂部C12的至少部分、下臂部C13的至少部分可以与机壳B11是一次注塑成型的整体部件,由此,可以有效地提高手柄壳C1与机壳B11的连接可靠性。优选地,持握部C11的至少部分、上臂部C12的至少部分和下臂部C13的至少部分为一体成型件,也就是说,持握部C11的至少部分、上臂部C12的至少部分和下臂部C13的至少部分可以是一次注塑成型的整体部件,由此,可以有效地提高手柄壳C1的结构可靠性。
例如,持握部C11可以包括握手内壳和握手外壳,上臂部C12可以包括上臂上壳和上臂下壳,下臂部C13可以包括下臂下壳和下臂上壳,其中,握手内壳、上臂下壳、下臂上壳可以与机壳B11为一体成型件,握手外壳可以可拆卸地安装在握手内壳的外侧,上臂上壳可以可拆卸地安装在上臂下壳的顶部,下臂下壳可以可拆卸地安装在下臂上壳的底部。
优选地,参照图22,壳体B1的外表面为圆柱形,上臂部C12与壳体B1的周面顶端相连,下臂部C13与壳体B1的周面底端相连。由此,可以提高手柄组件VC的整体尺寸,以更加有效地优化手持吸尘器V整机的重心,使用户可以更加省力地持握手持吸尘器V。
优选地,参照图22,壳体B1的外表面为圆柱形,持握部C11的中心线(即沿持握部C11长度方向延伸的中心线)、上臂部C12的中心线(即沿上臂部C12长度方向延伸的中心线)、下臂部C13的中心线(即沿下臂部C13长度方向延伸的中心线)和壳体B1的轴线位于同一平面内。由此,可以更加有效地优化手持吸尘器V整机的重心,使用户可以更加省力地持握手持吸尘器V。
下面,参照附图30、并结合图22-图33,简要描述根据本发明实施例的手持吸尘器V的工作原理。
当负压装置B3(例如由电机和风扇组成)启动时安装腔B1012内产生负压,与安装腔B1012连通的排气腔B1011、连通腔B105、除尘腔B102、吸气管B1113也产生负压,此时,手持吸尘器V外界环境中的尘气可以通过吸气管B1113吸入到除尘腔B102内,并沿切向进入第一旋风腔B1021内进行旋风分离,在第一旋风腔B1021内旋风分离出尘质向下坠落、并经过杯盖B124上的第一进尘口B1241进入到第一集尘腔B1031内、然后排入缓存腔B104内,而在第一旋风腔B1021内旋风分离出的气流可以通过过滤筒B211上的过滤孔B2110进入到第二旋风腔B1022内,并通过每个旋风筒B212侧壁上的切向入口B2120进入到多个旋风筒B212内进行旋风分离,在多个旋风筒B212内旋风分离出的尘质向下坠落、并经过杯盖B124上的多个第二进尘口B1242进入到第二集尘腔B1032内,而在多个旋风筒B212内旋风分离出的气流可以向上、并经过端盖B22上的出风管B222、和机盖B13上的过滤件B131和进风口进入到连通腔B105内,之后连通腔B105内的气流通过机盖B13上的出风口B1301排出到排气腔B1011内,然后气流再流经负压装置B3、并经过负压装置B3后侧的隔离网B5排向排风过滤装置B4,气流经过排风过滤装置B4的最终过滤从排风空间B106的底部排出到手持吸尘器V的外界环境中。
下面,简要描述根据本发明实施例的手持吸尘器V的几方面的有益效果。
1、相关技术中的手持吸尘器,供电装置和负压装置均设在手柄内,且供电装置通常设置在手柄的底部,从而致使手柄的体积大、重量大,不但不便于用户手持,而且手持费力、舒适度不高。
然而,根据本发明实施例的手持吸尘器V,通过将供电装置C2设置在手柄壳C1的顶部,同时将负压装置B3设在在尘杯B12内,从而有效地改善了手持吸尘器V的重心分布,提高了用户持握手持吸尘器V的舒适度,使得用户可以更加省力地使用手持吸尘器V,愉悦了用户体验。
2、相关技术中的手持吸尘器,除尘装置均固定在机体内部,用户不能自行将除尘装置拆卸出来进行清洗,这样,残留在除尘装置内的灰尘就很容易引发细菌滋生、并产生异味,从而会对下一次的使用造成二次污染,削弱整体的清洁效果。
然而,根据本发明实施例的手持吸尘器V,由于机盖B13可以很方便地打开,且除尘装置B2可以从机壳B11内部取出,从而方便用户对除尘装置B2进行清洁,避免机壳B11内部残留灰尘,避免细菌滋生和产生异味等问题,提高了手持吸尘器V整体的清洁效果。
3、相关技术中的手持吸尘器,负压装置通常设置在手柄内,从而致使手柄的体积大、重量大,不但不便于用户手持,而且手持费力、舒适度不高,另外,相关技术中还有一些手持吸尘器,负压装置设在杯壳内但是却被集尘腔包围、环绕整周,从而致使负压装置难以拆装,不便于维修。
然而,根据本发明实施例的手持吸尘器V,通过将负压装置B3设置在尘杯B12内,从而有效地改善了手持吸尘器V的重心分布,提高了用户持握手持吸尘器V的舒适度,而且,通过将尘杯B12的杯壳B122设置成侧部开口的环柱形状,使得负压装置B3可以从侧部的开口方便地拆装,从而方便负压装置B3的拆装、维修和更换。另外,由于除尘装置B2位于集尘腔B103外的除尘腔B102内,从而使得尘杯B12与除尘装置B2相对独立,集尘腔B103内的灰尘不易扬起、倒流到除尘腔B102内,进而可以提高除尘效果,减小吸气阻力,降低能耗。
4、根据本发明实施例的手持吸尘器V,将除尘装置B2和负压装置B3均设置在机壳B11内,且将除尘装置B2排布在负压装置B3的上侧,同时在机壳B11外设置尘杯B12,将尘杯B12的杯壳B122环绕负压装置B3不足一周,从而可以有效地优化手持吸尘器V的整机结构布局,提高了用户体验的舒适度。
5、根据本发明实施例的手持吸尘器V,将除尘装置B2和负压装置B3均设置在机壳B11内,且将除尘装置B2排布在负压装置B3的上侧,同时在机壳B11外设置尘杯B12, 将尘杯B12的杯壳B122环绕负压装置B3不足一周,而且,将供电装置C2设置在手柄壳C1的顶部,从而可以进一步优化手持吸尘器V的整机结构布局,提高了用户体验的舒适度。
6、根据本发明实施例的手持吸尘器V,由于负压装置B3的上端部可以利用多个旋风筒B212底部之间的扩容段空间,从而提高了空间利用率和尘杯组件VB的结构紧凑性,节省了壳体B1内部的空间,增加了尘杯B12的有效容积,缩小手持吸尘器V整机的尺寸,使得手持吸尘器V整机更加轻便,增强了用户的体验舒适度。
