下面首先参考图 1-图 3简单描述根据本发明实施例的吸尘器的进气装置。
如图 1所示, 根据本发明实施例的进气装置 200包括电机 210和从内到外依次套设 的第一电机罩 220、 第二电机罩 230和第三电机罩 240, 电机 210设在位于最内层的第 一电机罩 220内, 第一电机罩 220通过进气口 250与集尘装置 100连通。
如图 2所示, 第一电机罩 220的周壁上形成有第一出气口 221, 第二电机罩 230在 第一电机罩 220的外部,第二电机罩 230的周壁上形成有第一出气口 221偏离的第二出 气口 231,第二电机罩 230与第一电机罩 220之间通过第一出气口 221与第一电机罩 220 内部连通的第一风道 271。 优选地, 第二电机罩 230与第一电机罩 220之间的距离范围 在 5mm-40mm之间。
位于最外层的第三电机罩 240在第二电机罩 230的外部且与第二电机罩 230之间通 过第二出气口 231与第一风道 271连通的第二风道 272, 其中第一风道 271和第二风道 272构成风道 270。 第三电机罩 240具有与第二出气口 231偏离的出风口 260。
可选地, 第三电机罩 240包括一层罩体, 如图 2所示。 优选地, 第三电机罩 240与 第二电机罩 230之间的距离范围在 5mm_40mm之间。 当然, 本发明并不限于此, 在本发 明的另一些可选实施例中, 第三电机罩 240包括从内到外依次的多层罩体, 如图 3所示 的示例中, 第三电机罩 240包括第一子罩体 241和第二子罩体 242, 此时, 在第一子罩 体 241和第二子罩体 242之间还可以第三风道 273,与上述实施例中类似,第三风道 273 可以与第二风道 272连通,而出风口设在第二子罩体 242上以便将第三风道 273内流动 的气体排出。 优选地, 第三电机罩 240中每层罩体之间的距离范围在 5mm_40mm之间。
为了描述简便, 在下面的说明中, 均以第三电机罩 240为一层进行描述。 本领域内 普通技术人员可以理解, 当第三电机罩 240 包括从内到外依次的二层及二层以上罩体 时, 其内部空气的流动与一层罩体时空气的流动方式类似, 在此不再详细列举。
被电机吸入的空气进入第一电机罩 220内, 沿着第一电机罩 220的内壁流动, 并从 第一出气口 221到第一风道 271内流动,然后从第二电机罩 230的第二出气口 231流出 进入到第二风道 272内, 沿着第三电机罩 240的内壁流动到出风口 260, 并流出到后面 的排气装置 300中。 这样, 通过第一至第三电机罩 220、 220、 230之间的第一风道 271 和第二风道 272, 实现了气流的迷宫式流动, 延长了空气流动的风道长度, 因此可以给 紊乱的气流提供足够的空间而稳定下来, 从而降低了空气的流动。 而且, 由于第一至第 三电机罩之间由于气体的运动而形成了相对的真空, 这样, 可以大大降低了空气气流和 电机 210本身运转时产生的噪音和振动, 进而得到了更好的静音或超静音产品。
根据本发明实施例的吸尘器的进气装置, 由于延长了空气流动的风道长度, 使电机 产生的噪音要通过长且曲折的风道才能传到外界, 在风道中声音被大大减弱, 从而大大 降低了噪音。 另外, 根据本发明的吸尘器, 结构简单成本低。
可选地, 第一出气口 221包括多个第一出气孔 221 1, 如图 2所示, 多个第一出气孔 221 1在第一电机罩 220的部分周壁上沿轴向和周向均匀分布。 进一步地, 第二出气口 231包括多个第二出气孔 231 1, 多个第二出气孔 231 1在第二电机罩 230的部分周壁上 沿轴向和周向均匀分布。优选地, 第二出气口 231与第一出气口 221在径向方向上相对 远离设置, 也就是说, 多个第二出气孔 231 1和多个第一出气孔 221 1在径向方向上相对 远离设置。 当然, 第一出气口 221和第二出气口 231还可以分别均为一个开口。
在本发明一个具体的优选实施例中, 多个第一出气孔分布在第一电机罩 220的一半 周壁上, 多个第二出气孔分布在第二电机罩 230的另一半周壁上, 如图 2所示。 由此, 风道足够延长, 从而使得气流可以有尽可能大的空间稳定下来, 并减小噪音。
下面参考图 1描述根据本发明实施例的吸尘器。
根据本发明的吸尘器包括: 用于收集灰尘的集尘装置 100、 进气装置 200和排气装 置 300, 其中进气装置 200为上述第一方面实施例中描述的进气装置。
可选地, 集尘装置 100包括集尘袋或集尘杯。 进一步地, 集尘装置 100和第一电机 罩 220之间的进气口 250处设有用于过滤灰尘的滤网 1 10。
排气装置 300设在第三电机罩 240后且通过排气口 (图中未示出) 与吸尘器的外部 环境连通。 由此, 如图 1中箭头所示, 电机 210转动在第一电机罩 220内产生负压, 带有灰尘 的空气被紊乱地吸入集尘装置 100内, 在进气口 250处灰尘被过滤, 然后进入第一电机 罩 220内, 沿着第一电机罩 220的内壁流动, 并从第一出气口 221到第一风道 271内流 动, 然后从第二电机罩 230的第二出气口 230流出进入到第二风道 272内, 沿着第三电 机罩 240的内壁流动到出风口 260, 并流出到后面的排气装置 300中最后经由排风口排 出到大气中。
根据本发明实施例的吸尘器, 空气被吸入后实现了气流的迷宫式流动, 足够延长了 空气流动的风道长度, 从而稳定了气流流动, 而且大大降低了工作噪音。
下面再参考图 1-图 3对根据本发明实施例的吸尘器的工作过程进行具体描述, 其中 以第三电机罩 240包括一层罩体为例进行说明。
首先, 电机 210转动在第一电机罩 220内产生负压, 带有灰尘的空气被紊乱地吸入 集尘装置 100内, 在进气口 250处灰尘被过滤, 空气进入第一电机罩 220内。
如图 1和图 2中箭头所示, 气流从进气口 250处被电机 210吸入, 流入第一电机罩 220内,沿着第一电机罩 220的内壁流动,并从第一出气口 221到第一风道 271内流动, 然后从第二电机罩 230的第二出气口 230流出进入到第二风道 272内,沿着第三电机罩 240的内壁流动到出风口 260。
此时, 空气气流从出风口 260上排出到排气装置 300, 由于排气装置 300的风道的 横截面积逐渐变大, 进一步改变了空气气流的流速或频率, 从而大大地降低了空气气流 本身产生的噪音和振动, 进而使得吸尘器的静音效果更加明显。
根据本发明实施例的吸尘器中集成装置的具体构成以及进气、排气装置的其他构成以及 操作对于本领域普通技术人员而言都是已知的, 这里不再详细描述。
在本说明书的描述中, 参考术语 "一个实施例"、 "一些实施例"、 "示意性实施例"、 "示 例"、 "具体示例"、 或 "一些示例"等的描述意指结合该实施例或示例描述的具体特征、 结 构、 材料或者特点包含于本发明的至少一个实施例或示例中。 在本说明书中, 对上述术语 的示意性表述不一定指的是相同的实施例或示例。 而且, 描述的具体特征、 结构、 材料或 者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
尽管已经示出和描述了本发明的实施例, 本领域的普通技术人员可以理解: 在不脱 离本发明的原理和宗旨的情况下可以对这些实施例进行多种变化、 修改、 替换和变型, 本发明的范围由权利要求及其等同物限定。
