[9] 为了保证吸尘器的吸尘效果， 所述的吸尘器本体内还设有中心过滤器， 该中心 过滤器与旋风分离装置串联设置。
[10] 同样出于结构设计角度考虑， 所述的中心过滤器与旋风分离装置也可以釆用同 轴设置。
[11] 另外， 根据造型需要， 所述的抽吸装置可以设置在旋风分离装置的上端或下端
[12] 通常情况下， 为了确保更好的吸尘效果， 所述的旋风分离装置可以釆用多级旋 风分离装置， 由初级旋风分离器和次级旋风分离器串联设置而成。 次级旋风分 离器为多个， 且彼此并联设置。 次级旋风分离器可以设置在初级旋风分离器的 上方或下方， 且该次级旋风分离器至少部分地被围设在旋风分离装置的腔体中
[13] 与现有技术相比， 本发明的有益效果在于： 由于将抽吸装置的机体至少部分地 插入旋风气流的内部， 从而使抽吸装置的部分或者全部被嵌设在旋风分离装置 腔体内的旋风气流中， 在旋风分离装置内腔的旋风气流轴向长度不变的前提下 ， 使得整机占用的空间相应地减少， 即在保证旋风灰尘分离效果的同吋， 旋风 吸尘器的体积相应的减小， 方便了用户的使用、 同吋也给产品造型提供了更多 的设计空间。
[14] 下面结合附图和具体实施例对本发明的技术方案进行详细地说明。

具体实施方式
[26] 实施例一
[27] 图 2为本发明实施例一吸尘器立体图， 图 3为本发明实施例一吸尘器主体的剖面 结构示意图。 如图 2所示， 本实施例提供一种具有一级灰尘分离功能的吸尘器 B 。 结合图 3所示， 该吸尘器 B包括吸尘器主体 104， 该主体 104内设有旋风分离装 置 107和抽吸装置 106， 旋风分离装置 107包括由侧壁 110和底板 111围设而成的腔 体， 该腔体的下端为旋风灰尘收集区 107b。 该旋风分离装置 107设有空气入口 10 8和空气出口 109， 空气入口 108与旋风分离装置 107的侧壁 110呈切向设置。 抽吸 装置 106位于空气出口 109的上方， 分离之后的气流经由空气出口 109排出并进入 抽吸装置 106。 空气出口 109通常设置为带有多个通孔的网孔过滤结构， 在气 、¾? 从空气出口 109排出的过程中， 再次对气流中残余的粉尘杂质进行一次过滤。 在 本实施例中， 抽吸装置 106的机体部分嵌设在旋风分离装置 107的腔体中， 从而 使抽吸装置 106的机体部分地插入旋风分离装置 107的旋风气流内部， 使抽吸装 置 106外部和侧壁 110之间所夹设的空间也得到了充分的利用， 在该部分空间中 ， 旋风气流仍然可以进行旋风分离。
[28] 在图 3中， 气流方向如图中双点划线所示， 具体来说， 带有灰尘的气流从地刷 1 01的吸口经过硬管 102、 软管 103和空气入口 108进入旋风分离装置 107的内腔中 ， 带有灰尘及其他颗粒杂质的气流沿切向进入腔体并在其中呈螺旋运动， 在离 心力的作用下实现气固分离。 旋风分离装置 107主要包括旋风分离器 107a， 在腔 体下部的旋风灰尘收集区 107b内， 被分离出来的颗粒等杂质滞留在底板 111上， 洁净气流在抽吸装置 106的抽吸作用下从空气出口 109排出并释放到大气中。 为 了使吸尘器的布局更加合理， 在本实施例中抽吸装置 106与旋风分离器 107a同轴 设置。 为方便清空吸尘器内的垃圾， 底板 111与侧壁 110之间的结合可釆用枢轴 式或卡扣式等不同的连接方式 （未示出） 。
[29] 实施例二
[30] 图 4为本发明实施例二吸尘器立体图， 图 5为本发明实施例二吸尘器主体的剖面 结构示意图。 如图 4所示， 本发明实施例二提供一种具有二级灰尘分离功能的吸 尘器 C。 结合图 5所示， 该吸尘器 C的旋风分离装置 207主要包括旋风分离器 207a ， 其下端为旋风灰尘收集区 207b， 该区域用于存放从气流中分离出的灰尘等颗 粒。 旋风分离装置 207的空气出口 209同样可以如实施例一所述设置成带有多个 通孔的网孔过滤结构， 或釆用海棉、 尼龙网等粗过滤材料对气流中的粉尘杂质 进行过滤。 本实施例与实施例一的主要区别在于， 为了保证吸尘器的吸尘效果 ， 在旋风分离器 207a的下游串联设置中心过滤器 212， 中心过滤器 212与旋风分离 器 207a釆用同轴设置， 中心过滤器 212为 HEPA (高效空气微粒过滤器） 或 ULPA 超高效空气微粒过滤器） 。 如图 5所示， 本实施例中的中心过滤器 212位于旋 风分离装置 207的空气出口 209的内部。 在实际的应用中， 中心过滤器 212的位置 可以进行调整， 按各种不同的布局设计， 可以使其位于旋风分离装置 207的空气 出口 209上部或是下部。 空气入口 208、 空气出口 209、 中心过滤器 212和抽吸装 置 206依次连通。 在本实施例中， 抽吸装置 206部分嵌设在旋风分离装置 207的腔 体中， 更确切地说， 抽吸装置 206部分地插入旋风分离器 207a的旋风气流内部， 且位于空气出口 209和中心过滤器 212的上方， 使得抽吸装置 206外部和侧壁 210 之间所夹设的空间也得到了充分的利用， 旋风气流在该部分空间中仍然可以有 效地进行旋风分离。
[31] 如图 5所示， 本实施例中所提供的吸尘器的工作过程如下： 气流方向如图中双 点划线所示， 带有灰尘的气流从地刷 201的吸口经过硬管 202、 软管 203和空气入 口 208进入旋风分离装置 207的内腔中， 在旋风分离装置内部产生螺旋式运动， 形成旋风气流， 从而进行第一次灰尘分离， 从气流中分离出来的颗粒等杂质留 滞在旋风分离装置底板 211上。 带有少量颗粒的气流经过空气出口 209的网孔过 滤结构后， 再进入中心过滤器 212， 将气流中的粉尘杂质彻底清除干净， 通过过 滤器 212进行第二次灰尘分离。 洁净的气流在抽吸装置 206的抽吸作用下排出， 释放到大气中。
[32] 本实施例中的其他技术特征与实施例一相同， 在此不再赞述。
[33] 实施例三
[34] 图 6为本发明实施例三吸尘器立体图， 图 7为本发明实施例三吸尘器主体的剖面 结构示意图。 如图 6所示， 本实施例提供一种具有二级灰尘分离功能的吸尘器 D 。 结合图 7所示， 本实施例与前述两个实施例的区别在于， 其旋风分离装置为多 级旋风分离装置， 由初级旋风分离器和次级旋风分离器串联设置而成。 次级旋 风分离器为多个， 且彼此并联设置。 次级旋风分离器位于初级旋风分离器的下 方， 且该次级旋风分离器至少部分地被围设在旋风分离装置的腔体中。
[35] 具体来说， 如图 7所示， 本实施例中旋风分离装置 305包括初级旋风分离装置 30 7和次级旋风分离装置 317。 初级旋风分离装置 307主要包括初级旋风分离器 307a ， 带通孔的档板 313、 侧壁 310和底板 311围设成初级旋风灰尘收集区 307b。 该区 域用于存放从初级旋风分离器 307a分离出的灰尘等颗粒。 档板 313上至少设有一 个通孔。 次级旋风分离装置 317包括次级旋风分离器 312和次级旋风灰尘收集区 3 18。 次级旋风分离器 312为多个旋风分离器并联设置。 次级旋风分离器 312的旋 转轴心线围绕初级旋风分离器 307a的旋转轴心线呈圆周布局。 在本实施例中， 次 级旋风分离器 312位于初级旋风分离器 307a的下方。 次级旋风灰尘收集区 318由侧 壁 319和底板 311围设而成， 该区域用于存放从次级旋风分离器 312分离出的灰尘 等颗粒。 初级旋风灰尘收集区 307b位于次级旋风分离器 312和次级旋风灰尘收集 区 318的外围， 将次级旋风分离器 312和次级旋风灰尘收集区 318包围。 为方便清 空吸尘器内的垃圾， 底板 311与侧壁 310可釆用枢轴式或卡扣式等不同的连接方 式。
[36] 在本实施例中， 抽吸装置 306设置在初级旋风分离装置 307的内腔， 并部分地嵌 设在初级旋风分离器 307a中， 抽吸装置 306位于空气出口 309和次级旋风分离器 31 2的上方。 旋风气流在抽吸装置 306和侧壁 310之间所夹设的空间中仍然可以有效 地进行旋风分离。
[37] 如图 7所示， 本实施例中所提供的吸尘器的工作过程如下： 带有灰尘的气流从 地刷 301的吸口经过风道管 302和空气入口 308进入初级旋风分离装置 307的内腔 中， 在初级旋风分离装置内腔中产生螺旋式运动， 形成旋风气流， 在进行第一 次灰尘分离之后， 从气流中分离出来的颗粒等杂质通过档板 313上的通孔滞留在 初级旋风灰尘收集区 307b内。 带有少量颗粒的气流从空气出口 309进入次级旋风 分离器 312的空气入口 314， 在次级旋风分离装置的内腔中产生螺旋式运动， 形 成旋风气流， 从而进行第二次旋风分离。 从气流中分离出来的少量颗粒等杂质 滞留在次级旋风灰尘收集区 318内， 即底板 311上， 在抽吸装置 306的抽吸作用下 ， 洁净的气流通过次级旋风分离器 312的空气出口 315释放到大气中。
[38] 实施例四
[39] 图 8为本发明实施例四吸尘器立体图， 图 9为本发明实施例四吸尘器主体的剖面 结构示意图。 如图 8所示， 本实施例提供一种具有二级灰尘分离功能的吸尘器 E 。 结合图 9所示， 本实施例与实施例二近似， 同样是对实施例一的改进， 二者都 在旋风分离器的下游串联设置了中心过滤器， 且中心过滤器都设置在空气出口 内部。 但本实施例中抽吸装置与旋风分离器、 中心过滤器在吸尘器主体中的上 、 下位置关系与实施例二中二者的上、 下位置关系相反， 主体中相应的其他结 构也因此有适应性改变。
[40] 具体来说， 如图 9所示， 旋风分离装置 405包括初级旋风分离装置 407和中心过 滤器 412， 沿气流在吸尘器本体中的流向看， 中心过滤器 412仍然设置在初级旋 风分离器 407a的下游， 但如图 9所示， 抽吸装置 406设置在中心过滤器 412和初级 旋风分离器 407a的下方。 在本实施例中， 抽吸装置 406自身具有独立的壳体， 同 吋该抽吸装置 406部分地嵌设在初级旋风分离装置 407的内腔中， 更确切地说， 抽吸装置 406部分地嵌设在初级旋风灰尘收集区 407b的内腔中。 因此， 该抽吸装 置 406的壳体使其和初级旋风分离装置 407的腔体相对隔离开。 包围在抽吸装置 4
06壳体外围的初级旋风分离装置 407的腔体部分， 仍然可以有效地进行旋风分离 。 抽吸装置 406与初级旋风分离装置 407之间釆用上述的设置方式， 当从吸尘器 主体 404中取出旋风分离装置 405吋， 由于旋风分离装置 405与抽吸装置 406为分 腔设置， 用户在清倒垃圾吋， 抽吸装置 406仍置于吸尘器主体 404上， 旋风分离 装置 405显得较为轻巧、 使用更轻便。
[41] 如图 9所示， 本实施例中所提供的吸尘器的工作过程如下： 气流方向如图中双 点划线所示， 带有灰尘的气流从地刷 401的吸口经过硬管 402、 软管 403和空气入 口 408进入初级旋风分离装置 407的内腔中， 在初级旋风分离装置的内腔中产生 螺旋式运动， 形成旋风气流， 从而进行第一次灰尘分离， 从气流中分离出来的 颗粒等杂质滞留在旋风分离装置底板 411上。 带有少量颗粒的气流从空气出口 40 9进入中心过滤器 412， 通过过滤器 412进行第二次灰尘分离。 洁净的气流在抽吸 装置 406的抽吸作用下排出， 释放到大气中。
[42] 本实施例中的其他技术特征与实施例二相同， 在此不再赞述。
[43] 实施例五
[44] 图 10为本发明实施例五吸尘器立体图， 图 11为本发明实施例五吸尘器主体的剖 面结构示意图。 如图 10所示， 本实施例提供一种具有二级灰尘分离功能的吸尘 器 F， 本实施例是在实施例三基础上的改进。 二者均为多级旋风分离装置， 但不 同之处在于， 本实施例中抽吸装置与多级旋风分离器在吸尘器主体中上、 下位 置关系与实施例三相反， 主体中相应的其他结构也因此有适应性改变。
[45] 结合图 11所示， 本实施例中的旋风分离装置 505包括初级旋风分离装置 507和次 级旋风分离装置 517。 初级旋风分离装置 507的空气出口 509为带有通孔的网孔过 滤器和向外延伸的裙边结构 519。 次级旋风分离装置 517包括多个呈并联设置的 次级旋风分离器 512， 次级旋风分离器 512的旋转轴心线围绕初级旋风分离器 507a 的旋转轴心线呈圆周布局。 次级旋风分离器 512位于初级旋风分离器 507a的上方 。 初级旋风灰尘收集区 507b位于次级旋风灰尘收集区 518的外围， 将次级旋风灰 尘收集区 518包围。 在本实施例中， 抽吸装置 506自身具有独立的壳体， 同吋该 抽吸装置 506部分地嵌设在初级旋风分离装置 507的内腔中， 更确切地说， 抽吸 装置 506部分地嵌设在初级旋风灰尘收集区 507b的内腔中。 抽吸装置 506位于空 气出口 509、 初级旋风分离器 507a和次级旋风分离器 512的下方。 抽吸装置 506的 壳体将其与初级旋风分离装置 507的腔体相对隔离开。 该设置方式的有益效果与 实施例四相同， 在此不再赞述。
[46] 如图 11所示， 本实施例中所提供的吸尘器的工作过程如下： 气流方向如图中双 点划线所示， 带有灰尘的气流从地刷 501的吸口经过风道管 502和空气入口 508进 入初级旋风分离装置 507的内腔中， 在初级旋风分离装置内腔中产生螺旋式运动 ， 形成旋风气流， 从而进行第一次灰尘分离， 从气流中分离出来的颗粒等杂质 滞留在初级旋风灰尘收集区 507b内。 带有少量颗粒的气流从空气出口 509进入次 级旋风分离器 512的空气入口 514， 通过次级旋风分离装置内腔中产生螺旋式运 动， 形成旋风气流， 从而进行第二次灰尘分离。 从气流中分离出来的少量颗粒 等杂质滞留在次级旋风灰尘收集区 518内， 洁净的气流通过次级旋风分离器 512 的空气出口 515， 在抽吸装置 506的抽吸作用下排出， 释放到大气中。
[47] 本实施例中的其他技术特征与实施例三相同， 在此不再赞述。
[48] 综合上述五个实施例的内容可知， 实施例一提供了最简单的基本吸尘器结构设 置， 实施例二和实施例四在实施例一的基本结构基础上增加了中心过滤器的结 构设置， 实施例三和实施例五在实施例一基本结构基础上釆用的多级旋风分离 器的结构设置。 同吋， 实施例二、 四和实施例三、 五中抽吸装置和旋风分离装 置的上、 下位置关系相反。 实施例四、 五中抽吸装置和旋风分离装置为分腔而 非共腔设置。 但无论釆用各个实施例中的哪种结构方式， 与现有技术的不同在 于， 抽吸装置的机体至少部分地设置在旋风分离装置腔体中的旋风气流内部， 使抽吸装置腔体外围与旋风分离装置腔体内部之间的那部分空间得到有效的利 用， 仍然可以进行正常的旋风分离运动。 在旋风分离装置内腔的旋风气流流动 空间不变的前提下， 相应减小了吸尘器的体积， 其结构更加合理， 也给产品造 型提供了更多的设计空间。
[49] 实际应用中， 在实施例三和实施例五釆用多级旋风分离器的基础之上， 串联中 心过滤器的组合方式， 可以实现更好的除尘效果， 结合上述各个实施例所述内 容， 本领域技术人员完全能够实现这种组合。 另外， 本发明还适用于叶片型旋 风分离器， 即： 在旋风分离装置的进气位置设置导流叶片， 带有颗粒杂质的气 体从旋风分离装置的进气位置进入其内腔， 部分颗粒杂质与导流叶片撞击摩擦 而落下， 气流经导流叶片后仍然在腔体中产生螺旋运动， 对气固进行粗分离。 综上所述， 本发明保护并不局限于说明书具体实施方式中所列举的五个实施例 所描述的具体结构布局。 显然， 在本发明权利要求书的保护范围内， 还可以有 多种不同的变型和结构组合。
