请参考图 1 , 图 1为现有技术中一种典型吸尘器收集装置的结构示意 图， 图中箭头所示方向为吸尘器工作时尘屑的运动方向。
从图中箭头所示的方向可以看出， 在现有技术的吸尘器中， 动力电机 与过滤器 11连通， 将集尘室 12中的空气抽出， 在集尘室 12中形成负压， 使空气和尘屑在动力电机的作用下，依次经过吸尘管 13和风道，进入集尘 室 12, 绕过滤器 11旋转并按螺旋的趋势逐渐在集尘室 12内汇聚， 达到吸 尘的目的。
但是， 随着尘屑的增多， 收集到集尘室 12里的尘屑容易受动力电机的 影响， 产生向过滤器 11移动的趋势， 使尘屑粘附在过滤器 11上， 阻塞过 滤器 11的滤网。 这样不仅会增加动力电机的电耗， 增大吸尘器的噪音， 降 低除尘效率； 而且会影响过滤器 11的使用寿命， 增加过滤器 11的维护频 次， 并增加清洁成本。
因此， 如何减少粘附在过滤器 11上的尘屑， 延长过滤器 11的使用寿 命， 提高吸尘器的工作效率， 降低清洁成本， 是本领域技术人员目前需要 解决的技术问题。 发明内容

附图说明
图 1为现有技术中一种典型吸尘器收集装置的结构示意图； 图 2为本发明所提供收集装置一种具体实施方式的结构示意图； 图 3为图 2所示收集装置的工作原理示意图；
图 4为本发明所提供底座一种具体实施方式的结构示意图； 图 5为本发明所提供底板与过滤器轴线的夹角示意图；
图 6为本发明所提供底座和盖板一种具体实施方式的结构示意图。 具体实施方式
本发明的核心是提供一种用于吸尘器的收集装置， 该收集装置能有效 减少尘屑粘附在过滤器上， 从而延长过滤器的使用寿命， 降低过滤器的维 护频次， 降低清洁成本。 本发明的另一核心是提供一种包括上述收集装置 的吸尘器， 其工作效率得到提高。
本文所涉及的上、 下方位词， 是以尘屑进入吸尘管的管口位于最高点 为基准来定义的； 本文所述的轴向， 是以上述吸尘管的延伸方向为参考， 风道绕过滤器旋转时， 过滤器的高度方向为基准定义的。 应当理解， 本文 中所采用的方位词不应当限制本专利的保护范围。
为了使本技术领域的人员更好地理解本发明方案， 下面结合附图和具 体实施方式对本发明作进一步的详细说明。
请参考图 2和图 3 , 图 2为本发明所提供收集装置一种具体实施方式 的结构示意图，其中箭头所示方向为吸尘器工作时尘屑的运动方向示意图； 图 3为图 2所示收集装置的工作原理示意图， 其中实线箭头所示方向为动 力部件形成的动力方向， 虚线箭头所示方向为尘屑的运动方向。
本发明所提供的收集装置， 包括吸尘管 21、 集尘室 22、 风道 23 , 以 及设于集尘室 22内部的过滤器 24; 风道 23环绕过滤器 24, 其起始端 231 与吸尘管 21连通， 末端 232与集尘室 22连通。 与现有技术不同的是， 本 发明所提供的收集装置中，风道 23具有螺旋式结构，且起始端 231与末端 232在轴向上具有预定的距离， 即风道 23的螺旋式结构不是在一个平面内 螺旋， 而是在空间上有一定位移的螺旋式结构。 这样， 尘屑从吸尘管 21 中进入风道 23后， 沿螺旋式的风道 23逐渐向空间上移动，从风道 23中出 来后，在高速旋转的惯性下会继续在集尘室 22中按螺旋式的线路前进， 并 在空间上具有逐渐远离风道 23末端 232的趋势， 从而远离过滤器 24, 减 小尘屑粘附在过滤器 24上的可能， 以达到延长过滤器 24使用寿命、 降低 过滤器 24维护频次的目的， 从而降低清洁成本。 而且过滤器 24能长时间 保持洁净状态可以减小吸尘器的电耗， 降低吸尘器的噪音， 并提高吸尘器 的工作效率。
请参考图 4, 图 4为本发明所提供底座一种具体实施方式的结构示意 图。
在一种具体的实施方式中， 本发明所提供的收集装置还可以包括与吸 尘管 21和集尘室 22均固定连接的底座 25 , 该底座 25包括形成风道 23的 内壁 251、 外壁 252, 以及连接内壁 251和外壁 252的底板 253。 这样， 内 壁 251、 外壁 252和底板 253形成了凹模式的风道 23 , 尘屑依次经过吸尘 管 21和底座 25 , 然后进入集尘室 22, 该结构筒单， 而且与现有技术中的 收集装置相近，对现有技术的吸尘器作较小的改进即能实现本发明的技术， 其实现成本低， 有利于本发明所提供技术的推广。
显然， 此处的内壁 251和外壁 252, 是以过滤器 24为基础， 靠近过滤 器 24为内， 远离过滤器 24为外； 同时， 底板 253可以理解为距离顶端最 远的部分。 事实上， 风道 23可以是圓管形的， 其周向上可以是一个整体的 圓弧形。 应当理解， 上述的结构都属于收集装置的具体实施例， 都应该在 本发明的保护范围内。
请参考图 5 , 图 5为本发明所提供底板与过滤器轴线的夹角示意图。 在进一步的技术方案中，底板 253与过滤器 24的中心轴（图中的中线
A, 为虚拟结构）可以具有适当的角度， 使尘屑能更好地远离过滤器 24, 并汇聚于集尘室 22的端部。 如图 5所示， 底板 253与过滤器 24的角度 a 可以大于 45度， 小于 90度。 这样既能确保尘屑能保持螺旋的运动趋势， 而且能有效远离过滤器 24, 增加清洁效果。
为了达到更好的技术效果， 风道 23的内壁 251 最好能略高于过滤器
24的滤网底端。 使尘屑在风道 23里移动时， 即使与内壁 251碰撞， 也不 会粘附在过滤器 24的滤网上， 从而避免滤网堵塞， 延长过滤器 24的使用 寿命。 显然， 内壁 251如果不高于滤网底端时也能实现本发明的目的。
请参考图 6, 图 6为本发明所提供底座和盖板一种具体实施方式的结 构示意图。
具体地， 本发明所提供的收集装置还可以包括设于起始端 231的盖板 26, 该盖板 26与底座 25的上表面、 内壁 251和外壁 252均紧密连接。 即 通过盖板 26、 内壁 251和外壁 252在风道 23的起始端 231形成周向密闭 良好的通道，使尘屑进入风道 23后， 能在周向密闭的空间里唯一能沿风道 23前进， 避免气流紊乱， 提高除尘效率。
进一步地，风道 23的起始端 231与末端 232的轴向差距小于或等于螺 旋式结构的螺距， 即风道 23绕过滤器 24—周或者小于一周， 这样可以避 免风道 23过长， 增加吸尘器的生产成本， 而且避免增加电耗。 显然， 风道 23也不能太短， 至少应该能形成螺旋式结构， 能让尘屑从风道 23里送出 后具有螺旋上升的趋势。
在一种具体的实施方式中， 上述的吸尘管 21与集尘室 22可以并排设 置且具有一体式结构， 如图 2和图 3所示。 这样， 吸尘管 21和集尘室 22 可以通过注塑等方式一次性生产制得， 以减少吸尘器的零件数量， 降低吸 尘器的组装难度。
进一步地， 本发明所提供的吸尘管 21与集尘室 22均可以由透明的壳 体形成。 透明的壳体不仅美观漂亮， 而且尘屑在吸尘管 21和集尘室 22中 的状态可以直接观察， 使用者能直接得知集尘室 22中的尘屑数量和状态， 使吸尘器的性价比更高。
除了上述收集装置， 本发明还提供一种包括上述收集装置的吸尘器， 该吸尘器的动力部件与收集装置中的过滤器 24进口端连接，动力部件工作 时， 在收集装置中形成负压， 使尘屑进入集尘室 22, 达到吸尘清洁的技术 效果。 吸尘器其他各部分的结构请参考现有技术， 本文不再赘述。
具体地， 上述吸尘器可以是便捷式吸尘器， 便捷式吸尘器以其良好的 吸尘效果和质轻、 便捷的特点， 在现代生活中得到广泛应用， 特别是针对 家用汽车、 电脑等精密电器的小角落， 能发挥较好的技术效果。
以上对本发明所提供的吸尘器及其收集装置进行了详细介绍。 本文中 应用了具体个例对本发明的原理及实施方式进行了阐述， 以上实施例的说 明只是用于帮助理解本发明的方法及其核心思想。 应当指出， 对于本技术 领域的普通技术人员来说， 在不脱离本发明原理的前提下， 还可以对本发 明进行若干改进和修饰， 这些改进和修饰也落入本发明权利要求的保护范 围内。
