实施例一
如图 2和 3示， 本发明旋风分离装置包括第一旋风单元和第二旋旋风分离单元。 第一旋风单元包括尘桶 10和网孔过滤器 7。 尘桶 10设有切向进风口 10a， 该尘桶 10 用于进行气体与颗粒等脏物之间的气固分离， 其底部用于收集脏物； 网孔过滤器 7上 设有气孔 7a， 该气孔 7a为网孔过滤器 7上设有的多个通孔。 第二旋风分离单元位于 第一旋风分离单元的下游， 其包括分离器 3和连接桶 5， 分离器 3过滤小颗粒脏物， 分离器 3包括多个旋风筒体 31 , 旋风筒体 31上下端都开口， 旋风筒体 31侧壁上设有 两个切向进气口。 具体地说， 该两个进气口可以沿旋风筒体的旋转轴相位差 180度分 布。 为使旋风筒体 31的布局紧凑， 旋风筒体 31的轴心线与所述旋风分离装置的轴心 线之间设有一定夹角，夹角范围一般为 6 ° -12° 。本实施例中，两者之间的夹角为 8 ° 。 为提高第二次气流的分离效果， 旋风筒体 31侧壁上的两个进气口呈对称分布。分离器 3的下方设置有连接桶密封盖 4，连接桶密封盖 4上开设有圆孔， 圆孔个数与旋风筒体 31的个数相同， 圆孔的直径大于旋风筒体 31下端开口直径， 小于旋风筒体 31上端开 口直径。 旋风筒体 31通过连接桶密封盖 4的圆孔， 旋风筒体 31部分伸入连接桶 5， 通过连接桶密封盖 4的圆孔与连接桶 5相连接。 除此种方式之外， 连接桶密封盖 4开 设的圆孔的直径也可等于旋风筒体 31下端的开口直径， 小于旋风筒体 31上端开口直 径， 旋风筒体 31设置在连接桶 5上， 其下端开口对应于连接桶密封盖 4的圆孔， 通过 连接桶密封盖 4的圆孔使得旋风筒体 31与连接桶 5相连接。连接桶密封盖 4和连接桶 5密封连接。
图 4为旋风分离装置中的分离器俯视图。 如图 4所示， 分离器 3的排布为： 外侧 一周设置有多个旋风筒体 31， 旋风筒体可以是 6~ 12个， 本实施例中为 8个旋风筒体 31， 围绕分离器 3的中心轴均匀紧密排列。旋风筒体 31的侧壁上设有两个进气口， 分 别为第一进气口 31 a和第二进气口 31b。 第一进气口 31a的开口朝向分离器 3的外侧， 第二进气口 31b的开口朝向分离器 3的内侧。 第一进气口 31a和第二进气口 31b呈对 称分布， 且两个进气口的高度和截面积相同。 其中， 多个旋风筒体 31 的第一进气口 31a高度为同一高度， 多个旋风筒体 31的第二进气口 32a高度为同一高度。
为更有效地提升旋风分离效果， 如图 4所示， 在分离器 3中间另外设置一个中心 旋风筒体 32。 中心旋风筒体 32设置在分离器 3的中心位置， 中心旋风筒体 32侧壁上 设有两个进气口 32a， 两个进气口 32a的高度相同。 与此同时， 在连接桶密封盖 4的 中心位置相应的开设一个圆孔， 以使得连接桶密封盖 4上圆孔的数量与分离器 3上所 设的旋风筒体 31和中心旋风筒体 32的总数量相对应。
下面结合附图进一步说明旋风分离装置的工作过程。
如图 3和 5所示，夹带灰尘、颗粒等脏物的气流沿尘桶 10上的切向口 10a进入尘 桶 10， 气流在尘桶 10 内旋转， 进行第一次气固分离， 利用离心力将大颗粒脏物及部 分灰尘从气流中分离出去。进一步地， 网孔过滤器 7上所设有的挡尘环 9， 该挡尘环 9 有效防止二次扬灰， 防止二次扬灰的灰尘堵塞网孔过滤器 7设有的气孔 7a。 气固分离 后的脏物落入尘桶 10的底部。为保障旋风分离装置的分离效率， 旋风分离装置在不同 位置设有不同的密封圈， 比如： 设置在尘桶 10和尘桶底盖 12之间的尘桶底盖密封圈 11， 其有效防止泄气漏灰； 设置在尘桶 10和网孔过滤器 7之间的尘桶密封圈 8， 其有 效防止位于尘桶 10中的气流未经网孔过滤器的气孔 7a直接进入分离器 3中。 第一次 气固分离的气流通过网孔过滤器 7上的气孔 7a进入第二分离单元，沿连接桶 5的外壁 向上运动。
第一次分离后的气流包括第一气流 41a和第二气流 41b， 第一气流 41a通过第一 气流通道进入第一进气口 31a和第二气流 41b通过第二气流通道进入第二进气口 31b 的过程如下。
第一气流 41a通过网孔过滤器 7的内壁与连接桶 5的外壁之间的缝隙向上运动， 到达连接桶 5的上端口处， 再沿着位于分离器 3的外壁、 锥孔盖 1的内壁以及网孔过 滤器 7的内壁之间的缝隙向上运动， 从第一进气口 31a直接进入旋风筒体 31内， 第一 气流通道包括： 连接桶 5外壁与网孔过滤器 Ί内壁之间的缝隙和分离器 3外壁、 锥孔 盖 1的内壁以及网孔过滤器 7的内壁之间的缝隙。 第二气流 41b通过网孔过滤器 7的 内壁与连接桶 5的外壁之间的缝隙向上运动， 到达连接桶 5的上端口处， 经过分离器 3外壁上的凹槽 301进入到旋风筒体 31外壁之间的缝隙。此时，气流沿着旋风筒体 31 外壁之间的缝隙向上运动， 由此进入旋风筒体 31的第二进气口 31b。 第二气流通道包 括连接桶 5外壁与过滤器 7内壁之间的缝隙、 分离器 3外表面的凹槽 301、 旋风筒体 31外壁之间的缝隙。 从第一进气口 31a和第二进气口 31b进入的第一气流 41a和第二 气流 41b在旋风筒体 31内汇合，汇合后气流利用离心力的分离， 分离出的脏物通过旋 风筒体 31下端开口落入连接桶 5中， 经过第二次气固分离的气流通过旋风筒体 31上 端开口排出。 位于分离器 3上的分离器密封圈 2将分离器 3的上端部与锥孔盖 1进行 密封， 有效防止泄气的作用。 过滤垫 13位于锥孔盖 1和尘桶盖 16之间， 用于过滤经 过旋风筒体 31第二次分离后的气流， 进一步过滤夹杂的细小灰尘，保证排出气流是干 净的。 尘桶盖密封圈 14设置在尘桶盖 16和锥孔盖 1之间进行密封， 有效防止泄气的 作用。 尘桶盖上设有安全阀 15、 操作尘桶释放按钮 19和弹性部件 18， 如果旋风分离 装置堵塞时， 安全阀 15弹起， 可以防止电机温度过高， 有效保护电机； 操作尘桶释放 按钮 19， 可以方便地从旋风分离装置上取出和安放尘桶 10 ; 弹性部件 18保证尘桶释 放按钮 19操作完成后复位。 实施例二
图 6所示为本发明实施例二旋风分离装置中的分离器的结构示意图。如图 6所示， 本实施例二与实施例一之间的区别仅在于： 实施例二中的分离器 3由多个旋风筒体 31 围设而成， 多个旋风筒体 31的外表面并不包含带有凹槽的外壁。将此分离器 3放置在 已装有连接桶密封盖的连接桶上， 该分离器 3与连接桶之间存有间隙。
在此旋风分离装置中， 经过第一级旋风分离单元进行气固分离后， 分离后的气流 进入第二级旋风分离单元。 第一次分离后的气流分成第一气流和第二气流。 第一气流 行走的方式与实施例一相同， 即： 第一气流经过网孔过滤器的内壁和连接桶的外壁之 间的缝隙以及过滤器的外壁、 锥孔盖的内壁和网孔过滤器的内壁之间的缝隙。 第二气 流在通过网孔过滤器的内壁和连接桶之间的缝隙之外， 其直接通过旋风筒体外壁之间 的缝隙进入第二进气口。
本实施例通过减少实施例一在分离器上设有的凹槽， 而将第二气流的气流通道设 计得更为简洁， 同时通过减材降本达到了同样的作用和功效。
总之， 在本发明中， 一部分进气通道设置在旋风筒体 31 之间的缝隙， 可以使第 二旋风分离单元有更多的可利用空间， 以增加旋风筒体 31的进气口截面积， 进一步提 高空气净化效率。
图 7为本发明直立式旋风吸尘器立体图， 如图 7所示， 该直立式旋风吸尘器 100 包括吸尘器主体 101和吸头 130， 该主体 101设置有电风机单元 （图中未示）， 电风机 单元作为旋风发生器用于产生抽吸力。 吸头 130与吸尘器主体 101相连通， 用于从待 清洁表面吸入带有灰尘的空气。 直立式旋风吸尘器 100包括旋风分离装置 102， 该旋 风分离装置 102安装在吸尘器主体 101上，其与吸尘器主体 101和吸头 130的相连通， 用于实现气固分离， 干净的气流通过电风机单元的出口释放到大气中。 当灰尘颗粒集 满后， 使用者可以将旋风分离装置 102从吸尘器主体 101上取出， 实现倒灰功能。
图 8为本发明卧式旋风吸尘器的立体图， 如图 8所示， 卧式旋风吸尘器 200包括 吸尘器主体 201和吸头 230， 该主体 201设置有电风机单元 （图中未示）， 电风机单元 作为旋风发生器用于产生抽吸力。 吸头 230与吸尘器主体 201相连通， 用于从待清洁 表面吸入灰尘和空气。 所述卧式旋风吸尘器 200包括旋风分离装置 202， 该旋风分离 装置 202安装在吸尘器主体 201上， 其与吸尘器主体 201和吸头 230的相连通， 用于 实现气固分离， 干净的气流通过电风机单元的出口释放到大气中。
本发明保护并不局限于说明书具体实施方式中所列举的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。
