[0031] 实施例一； 如图 1、 图 2、 图 3所示为本发明实施例的立体示意图、 剖面示意图 和爆炸状态示意图， 该吸尘器由位于吸尘器上部的盖体 100和下部的主体 200组 成， 以及用于为吸尘器提供真空源的真空电机 205， 对含尘气流进行尘气分离的 分离装置 101， 和容纳分离后灰尘的集尘装置： 集尘桶 202， 集尘袋 211， 分离后 的干净气流通过设置于所述的真空电机 205下游的出风口 301排出， 所述的真空 电机 205的上游并联连接有为含尘气流流入提供真空负压的第一通道 204和连接 所述的集尘桶 202为所述的集尘袋 211提供真空负压的第二通道 2041， 所述的集 尘桶 202设置有通气孔 2021， 所述的通气孔 2021构成所述的第二通道 2041的一部 分， 通过所述的第二通道 2041， 在所述的真空电机 205负压下， 所述的集尘袋 21 1扩张紧贴于所述的集尘桶 202内壁， 为容纳分离后灰尘作准备。 所述的真空电 机 205和集尘装置 202、 211设置于所述的主体 200内， 所述的分离装置 101设置于 所述的盖体 100上， 所述的盖体 100能从所述的本体 200上打幵。 在本实施例中所 述的分离装置 101为旋风分离装置， 所述旋风分离装置 101的排灰口 1012朝向所 述的集尘装置 （202、 211) ， 所述的集尘装置包含容纳分离后灰尘的集尘袋 211 和容纳集尘袋 211的集尘桶 202， 所述的旋风分离装置 101至少部分地插入所述的 集尘袋 211内， 所述的集尘袋 211为非气体穿透材质的塑料薄膜材质。
[0032] 所述的旋风分离装置 101的下游， 所述的真空电机 205之前设置有用于进一步过 滤灰尘的电机前过滤器 102， 所述的电机前过滤器 102优先地设置于所述的盖体 1 00内。 在本实施例中， 所述的电机前过滤器 102设置在一个过滤器导风管 103中 ， 所述的过滤器导风管 103固定地安装于盖体 100上。 气流通过进风口 2001进入 设置在本体 200内的一个进风导管 209， 进风导管 209， 通过一个进风导管密封圈 210与设置在盖体 100内的分离装置进风口导风管 105连通， 分离装置进风口导风 管 105连接分离装置 （旋风分离装置） 101上的分离装置进风口 1011， 气流导入 旋风分离器 101， 进行旋风尘气分离， 灰尘被旋风分离器 101分离后从排灰口 101 2排入集尘袋 211 ;
[0033] 分离后的气体通过过滤器导风管 103， 流经设置在过滤器导风管 103内的电机前 过滤器 102， 进一步地分离细小的颗粒灰尘， 干净的气流从过滤器导风管 103流 出， 通过电机进风导管密封圈 203进入第一通道 204， 进入真空电机 205。 如图 2 和图 4中的虚线箭头为流经第一通道 204的气流方向。 在吸尘器工作， 所述的真 空电机 205为第一通道 204气流流入提供真空负压的同吋， 真空电机 205通过并联 连接的第二通道 2041为所述的集尘袋 211提供真空负压， 将所述的集尘桶 202和 集尘袋 211之间的空气抽走， 从而使所述的用非过滤材质塑料制作的集尘袋 211 扩张， 紧贴于集尘桶 202的内壁， 方便分离后灰尘的排入， 为容纳分离后灰尘作 准备。 如图 4中实线箭头为流经第二通道 2041的气流方向。
[0034] 电机罩 206由电机罩上 2061和电机罩下 2062组成， 一方面可以防止气流外泄， 一方面可以降低吸尘器的噪音， 真空电机 205的上下端分别用电机上密封压座 20 71和电机下压座 2072固定在电机罩 206内， 出风过滤器 208设置在电机罩下 2062 朝向气流下游的方向上， 从真空电机 205排出的气流经过出风过滤器 208排出最 终从本体 200和底座 300间的间隙出风口 301排出， 出风过滤器 208进一步地净化 气流， 避免环境污染。 为了清楚地了解气流的流经方向， 图 4为本发明吸尘器内 部结构示意图， 其中的虚线箭头方向表示流经第一通道 204的气流方向， 实线箭 头为流经第二通道 2041的气流方向。
[0035] 在所述的集尘桶 202、 集尘袋 211和所述的旋风分离装置 101之间设置有用于密 封所述集尘桶 202、 集尘袋 211的密封圈 104， 这样便于在真空电机 205通过所述 第二通道 2041排空集尘桶 202和集尘袋 211之间的空气， 所述集尘袋 211紧贴所述 的集尘桶 202， 为灰尘排入容纳分离后灰尘做准备， 同吋避免了除进风口 2001夕卜 ， 外部气流进入吸尘器， 保障吸尘器的正常工作。 含尘气流分离后， 沿着排灰 口 1012方向被旋转甩入集尘袋 211内。 本体盖 201用于护住集尘桶 202， 在盖体 10 0从主体 200上打幵后， 所述的集尘袋 211可以从集尘桶 202内取出废弃， 进行倒 灰。 重新使用吋更换新的集尘袋 211， 盖上盖体 100后， 集尘桶 202、 集尘袋 211 和所述的旋风分离装置 101之间通过设置在盖体 100上的密封圈 104再次进行密封
[0036] 如图 5所示为盖体 100从主体 200上打幵后的状态， 盖体 100通过主体 200上设置 的幵盖转轴 500旋转打幵， 便于提取和更换集尘袋 211。 当然盖体 100从主体 200 上打幵的方式有很多， 本案例只是略举一例。
[0037] 所述的主体 200的下方设置有支撑所述主体 200的底座 300， 底座 300上可选择地 安装有移动轮 302， 便于该吸尘器在地面上拖动如图 2， 图 3所示。
[0038] 实施例二； 如图 6、 和图 7所示为本发明实施例的剖面和内部结构示意图， 与实 施例一不同的是： 所述的进风口 2001可以直接地吸取地面的灰尘， 其进风口 200 1设置的位置比较低， 当地面的灰尘出现在进风口 2001的附近吋， 就被气流带走 ， 这种方式通常该吸尘器不需要移动， 所以通常不需要移动轮 302。
[0039] 当该吸尘器幵启吋， 通过其它途径将地面的灰尘赶到进风口 2001附近吋， 借助 真空电机 205巨大的吸力， 经灰尘带入进风口 2001， 分别依次流经进风导管 209 通过进风导管密封圈 210进入分离装置进风口导风管 105，
通过分离装置进风口 1011， 进入旋风分离器 101， 灰尘被旋风分离器 101分离后 从排灰口 1012排入集尘袋 211 ; 分离后的气体通过过滤器导风管 103， 流经设置 在过滤器导风管 103内的电机前过滤器 102， 进一步地分离细小的颗粒灰尘。 干 净的气流从过滤器导风管 103流出， 通过电机进风导管密封圈 203进入电机进风 导管 204进入真空电机 205， 最后流经出风过滤器 208从出风口 301排出。 图中虚 线箭头方向表示流经第一通道 204的气流方向， 该气流为吸尘器吸尘气流， 实线 箭头为流经第二通道 2041的气流方向， 该气流为为集尘袋 211扩张， 为容纳分离 后灰尘作准备。
