Description

甩灰组件、尘杯和吸尘器 技术领域
本申请涉及室内清洁电器，具体地，涉及一种甩灰组件。在此基础上，本申请还涉及一种尘杯。此外，本申请还涉及一种吸尘器。
背景技术
吸尘器是一种室内清洁卫生的家用电器，用于清除地面、地毯、墙壁、家具及各种缝隙中的灰尘。按照吸尘器的外形分类，可分为立式吸尘器、卧式吸尘器和手持式吸尘器等。
其中，手持式吸尘器的工作原理是通过电机带动叶轮高速旋转，以将吸尘器内部的空气向外排出，在吸尘器内部形成瞬时真空，与外界大气形成一个相当高的负压差。在此负压差的作用下，吸尘器会将吸口处的空气连同灰尘一起通过进气口吸入吸尘器的尘杯内。含有灰尘的空气在尘杯内经过一系列的过滤后再将空气从出风口排出到吸尘器外部。以此达到清除灰尘、洁净清洁面的效果。
现市面上的手持式吸尘器大多都通过具有甩灰组件的尘杯实现灰尘与空气的分离。目前，部分尘杯在倾倒灰尘时需将甩灰组件从尘杯壳体上拆卸下来，倾倒完成后再装回尘杯壳体中，且吸尘器使用一定时间后甩灰组件内常会积累一定灰尘，需经常从尘杯壳体中拆卸下来进行清洁。但现有的甩灰组件通常零件较多，结构复杂，拆装很不方便。
有鉴于此，有必要提供一种甩灰组件，以解决目前手持式吸尘器的甩灰组件零件较多，结构复杂和拆装不便的问题。

优选地，所述过滤部可拆卸地安装在所述旋风锥上。
本申请的另一个方面还提供了一种尘杯，包括用于收纳灰尘的尘杯壳体，所述尘杯还包括如上所述的甩灰组件，所述甩灰组件安装在所述尘杯壳体内部，所述尘杯壳体的一端设有进风口，所述旋风锥端盖与所述尘杯壳体之间形成作为第二甩灰腔的螺旋通道，所述旋风锥与所述尘杯壳体之间形成第三甩灰腔，所述螺旋通道的一端与所述进风口连通、另一端与所述第三甩灰腔连通，以使气流进入所述第三甩灰腔内形成螺旋气流。
优选地，所述旋风锥端盖面向所述进风口的端面与所述尘杯壳体之间形成第一甩灰腔，所述螺旋通道的一端通过所述第一甩灰腔与进风口连通，以使所述第一甩灰腔内形成螺旋气流。

具体实施方式
以下结合附图对本申请的具体实施方式进行详细说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本申请，并不用于限制本申请。
在本申请中，在未作相反说明的情况下，使用的方位词如“上、下、左、右”通常是指参考附图所示的上、下、左、右；“内、外”是指相对于各部件本身的轮廓的内、外。
参照图1-3所示，一种甩灰组件100，所述甩灰组件100包括旋风锥端盖1和具有第一端2a和第二端2b的旋风锥2，所述旋风锥2从所述第二端2b向所述第一端2a逐渐收缩，所述旋风锥端盖1与所述旋风锥2的第一端2a连接且为用于将气流导送至所述旋风锥2处的螺旋结构，在所述旋风锥2的内部为风腔2c，所述风腔2c的腔壁2d上形成有进风孔21。
所述螺旋结构可为螺旋叶片或螺旋通道201等。通过旋风锥端盖1与旋风锥2的第一端 2a连接，使甩灰组件100形成一个整体，在拆装时可以作为整体从尘杯1000壳体中取出，结构简单紧凑，方便拆卸；通过将旋风锥端盖1设计成螺旋结构，以及对旋风锥2的使用，使甩灰组件100能够形成螺旋气流，实现甩灰；在旋风锥2上设置进风孔21，该进风孔21与旋风锥端盖1和旋风锥2的直线排列方式结合，使得气流流动更加快速顺畅，提高清洁效率，并且使气流在流入旋风锥2之前得到过滤，提高清洁效果，当气流在旋风锥2的风腔2c中形成螺旋气流时，可实现进一步甩灰，进而提高了清洁效果。另外，由于零件较少，结构紧凑，所述甩灰组件100安装在尘杯1000中时占据空间较小，增加了尘杯1000容纳灰尘的空间，同时，也可在尘杯1000容纳空间不变的情况下减小尘杯1000整体的体积。
为了方便甩灰组件100的清洁，或者在旋风锥端盖1或旋风锥2损坏后方便更换，优选地，所述旋风锥端盖1与所述旋风锥2可拆卸式地连接。
实现旋风锥端盖1与旋风锥2之间可拆卸地连接的方式可以有很多，其中一种优选的实施例为，在所述旋风锥端盖1面向所述旋风锥2的端面上设有多个卡扣11，每个所述卡扣11的前端形成为拆卸部11a，在所述旋风锥2的第一端2a的端面上设有多个与各所述卡扣11一一配合的卡口23，以使所述卡扣11与相应所述卡口23配合时所述拆卸部11a能够通过该卡口23伸入旋风锥2的风腔2c内。由于卡扣11与相应卡口23配合后，拆卸部11a位于旋风锥2的风腔2c内，需分离旋风锥端盖1和旋风锥2时，用户可将手伸入旋风锥2的风腔2c内并作用在拆卸部11a上，使卡扣11与相应卡口23分离，实现拆卸。其中，卡扣11可为端部带有回钩12的弹性杆件，弹性杆件在插入相应卡口23配合时会产生弹性变形，回钩12通过卡口23伸入旋风锥2的风腔2c内后，弹性杆件在弹力作用下恢复原形状，使回钩12钩挂在第一端2a位于旋风锥2风腔2c中的平面上，实现旋风锥端盖1与旋风锥2之间的连接，此时，所述拆卸部11a即为该回钩12。在分离旋风锥端盖1和旋风锥2时，用户挤压回钩12，使相应弹性杆件变形，回钩12挤压入相应卡口23中时，即可实现旋风锥端盖1和旋风锥2的分离。卡扣11以及相应卡口23的个数可以为多个，一般优选为2至6个，本申请中采用4个。除采用卡扣11与卡口23实现可拆卸式连接，还可以通过采用螺纹连接等其他连接方式实现旋风锥端盖1与旋风锥2的连接。
为使旋风锥2内部能够得到持续的且具有一定强度的旋风，优选地，所述进风孔21从所述旋风锥2外部向所述旋风锥2内部倾斜延伸，以使气流通过各所述进风孔21以旋风形式进入所述旋风锥2的风腔2c。所述“倾斜”是指进风孔21的延伸方向与旋风锥2的轴线不平行，且在旋风锥2径向方向上与旋风锥2的轴线有一定距离。进风孔21的延伸方向可设计为与旋风锥2外部螺旋气流旋向相同。进风孔21可设计为多个，多个进风孔21可环绕所述轴线均匀分布在所述风腔2c的腔壁2d上，也可沿所述轴线延伸方向分布在所述风腔2c的腔壁2d上。
对于进风孔21的延伸方向可以优选为，所述进风孔21沿该进风孔21所在位置的切向延伸。
此时，气流和灰尘直接以切向进入旋风锥2内，不会因与旋风锥2的风腔2c腔壁2d碰撞而产生能量消耗，因此具有较大的速度，而灰尘在与旋风锥2的风腔2c腔壁2d之间摩擦力的作用下速度会逐渐降低，进而使向心力逐渐减小，并在自身重力的作用下向下掉入旋风锥2的风腔2c底部，实现空气与灰尘的分离。
为使经过一系列甩灰过程的气流能够在得到彻底过滤的情况下排出，优选地，所述甩灰组件100还包括安装在所述旋风锥2的第二端2b且用于过滤的气流的过滤部3，所述过滤部3包括覆盖所述第二端2b的端口的过滤层33，所述过滤层33的面积大于所述第二端2b的端口的面积以使所述过滤层33能够在所述气流的作用下向所述旋风锥2外凸出。通过过滤层33能够实现对从旋风锥2流出的气流的过滤，由于过滤层33的面积大于所述端口的面积且能够在气流的作用下向旋风锥2外凸出，提高了过滤效率，进而提高了甩灰组件100的清洁效率。
当使用带有所述甩灰组件100的吸尘器10000进行清洁时，吸尘器10000通电开始吸尘的瞬间过滤层33会被气流撑起，不但产生较大噪音，而且由于瞬间产生较大速度又在之后瞬间停止，使过滤层33很容易损坏，为避免这一问题进一步优选地，所述过滤部3还包括支撑架31，所述支撑架31一端抵接所述旋风锥2、另一端抵接所述过滤层33，以使所述过滤层33向所述旋风锥2外凸出。由于支撑架31使过滤层33保持一个向过滤层33外凸出的状态，因此，在甩灰件内初始进入气流的瞬间，过滤层33不会产生较大瞬时速度，由此避免了因此产生的噪音和过滤层33容易损坏的问题。支撑架31可由杆件构成，避免对旋风锥2的风腔2c内的气流产生阻碍。
为实现安装过滤部3后甩灰组件100仍能较方便的拆卸，以便清洁或更换零件，进一步优选地，所述过滤部3可拆卸地安装在所述旋风锥2上。此时，更便于清洁旋风锥2的风腔2c内的灰尘。过滤部3与旋风锥2之间的可拆卸连接可以通过很多方式实现，例如，可以通过如前面所述的卡扣与卡口配合的方式实现，或者通过旋转卡合的方式实现。如图3所示，所述旋转卡合的方式可以为一下优选方式。将过滤部3设计为圆筒形，在过滤部3外壁上设置若干径向凸出的旋转卡扣32，在旋风锥2的第二端2b端口内设置有与旋转卡扣32配合的配合部22，配合部22用于容纳旋转卡扣32且个数和位置与旋转卡扣32相应，并且二者一一对应的配合，配合部22上设置有卡板221，过滤部3与旋风锥2配合时，旋转卡扣32伸入相应配合部22中，旋转过滤部3或旋风锥2使旋转卡扣32旋转至卡板221的位置，使卡板221将旋转卡扣32限制在配合部22内部，完成过滤部3与旋风锥2的连接；需要分离过滤部3和旋风锥2时，则再次转动过滤部3或旋风锥2，使旋转卡扣32脱 离卡板221的限制，并从配合部22中取出旋转卡扣32完成分离。旋转卡扣32以及相应配合部22的数量一般优选为2-6个，本申请中采用3个。
本申请中，为了实现较理想的甩灰效果，可将旋风锥端盖1、旋风锥2和过滤部3设计为轴线重合。并且，旋风锥端盖1和旋风锥2可采用PP料、ABS或PVC等制作，过滤部3的框架可采用低密度聚乙烯LDPE制作，过滤层33可采用无纺布制作。
当然，为了使甩灰组件100整体性更好，可将旋风锥端盖1与旋风锥2一体成型，或者旋风锥2与过滤部3一体成型，再或者将旋风锥端盖1、旋风锥2和过滤部3三者一体成型。
如图2和3所示，本申请的另一个方面还提供一种尘杯1000，该尘杯1000包括用于收纳灰尘的尘杯壳体4，所述尘杯1000还包括如上所述的甩灰组件100，所述甩灰组件100安装在所述尘杯壳体4内部，所述尘杯壳体4的一端设有进风口41，所述旋风锥端盖1与所述尘杯壳体4之间形成作为第二甩灰腔300的螺旋通道201，所述旋风锥2与所述尘杯壳体4之间形成第三甩灰腔400，所述螺旋通道201的一端与所述进风口41连通、另一端与所述第三甩灰腔400连通，以使气流进入所述第三甩灰腔400内形成螺旋气流。如图3所示，所述第二甩灰腔300为区域II中旋风锥端盖1与尘杯壳体4之间形成的螺旋通道201，所述第三甩灰腔400为区域III中旋风锥2与尘杯壳体4之间的空间。在第三甩灰腔400中可以安装导风板42，导风板42可为与旋风锥2锥度相同的弧形板，以使第三甩灰腔400内产生与旋风锥2外壁或内壁相切或近似相切的气流，进而使该气流能够以旋风锥2壁的切向进入旋风锥2的风腔2c内，提高在旋风锥2的风腔2c内的甩灰效果，其中，导风板42可为多块。另外，为使气流从第二甩灰腔300进入第三甩灰腔400的后形成螺旋气流，气流从第二甩灰腔300流出的方向要相对旋风锥2的轴线倾斜，一种优选的方式为，气流紧贴第三甩灰腔400相应的尘杯壳体4内壁并以与相对所述轴线倾斜的角度从第二甩灰腔300送出。
为进一步提高甩灰效果，优选地，所述旋风锥端盖1面向所述进风口41的端面与所述尘杯壳体4之间形成第一甩灰腔200，所述螺旋通道201的一端通过所述第一甩灰腔200与进风口41连通，以使所述第一甩灰腔200内形成螺旋气流。如图3所示，所述第一甩灰腔200为区域I与尘杯壳体4之间重叠的部分。为使所述第一甩灰腔200内能够在第二甩灰腔300引导下形成螺旋气流，气流进入第二甩灰腔300的方向要相对旋风锥端盖1的轴线倾斜，一种优选方式为，气流紧贴第一甩灰腔200相应的尘杯壳体4内壁并以与相对所述轴线倾斜的角度送入第二甩灰腔300。通过增加第一甩灰腔200，使在气流进入旋风锥2之前就进行了三级甩灰，实现了理想的清洁效果。
本申请再一个方面，还提供一种吸尘器10000，包括抽吸部2000，所述吸尘器10000还包括如上所述的尘杯1000，所述抽吸部2000与所述尘杯1000远离所述进风口41的一端 连接，以使抽吸部2000产生的抽吸气流将灰尘从所述进风口41送入所述尘杯1000。进风孔21可以直接与灰尘产生作用进行吸尘，或者与吸尘管或其他具有相同功能的设备连接，通过吸尘管或其他具有相同功能的设备与灰尘作用，实现吸尘。
以上结合附图详细描述了本申请的优选实施方式，但是，本申请并不限于上述实施方式中的具体细节，在本申请的技术构思范围内，可以对本申请的技术方案进行多种简单变型，这些简单变型均属于本申请的保护范围。
另外需要说明的是，在上述具体实施方式中所描述的各个具体技术特征，在不矛盾的情况下，可以通过任何合适的方式进行组合。为了避免不必要的重复，本申请对各种可能的组合方式不再另行说明。
此外，本申请的各种不同的实施方式之间也可以进行任意组合，只要其不违背本申请的思想，其同样应当视为本申请所公开的内容。
