Description

多筒灰尘分离结构式尘桶
技术领域
[0001] 本发明涉及真空吸尘器, 具体涉及真空吸尘器的尘桶。
背景技术
[0002] 随着人们生活水平和生活质量不断提高, 对家庭的卫生要求也越来越高。 同时随着 工业生产的快速发展, 环境的污染也越来越厉害, 空气中的灰尘日渐增多, 漂浮到家庭的 各个表面、 角落堆积, 容易引起细菌和病毒的滋生, 损害人们的生活环境和身体健康。 在 这种情况之下, 市场上大量的各种吸尘设备也就孕育而生, 为人们消除了无尽的烦恼。
[0003] 真空吸尘器的尘桶(或称尘杯), 是真空吸尘器的核心部件, 它将吸尘器吸入的带有 灰尘的空气进行分离、 过滤并存放尘粒。 通过尘桶内部结构的设计, 使工作时空气能在尘 桶内形成一次或多次的旋风, 以将空气中的尘粒进行分离, 故尘桶的内部结构直接影响吸 尘器的性能。
[0004] 现市场上具代表性的尘桶结构, 可见中国专利局于 2001年 10月 17日授权公告的, 专利号为 ZL00266255.8, 公告号为 CN2453827Y, 名称为《吸尘器的分体式旋风滤尘装置》 的实用新型专利。 该专利公开了一种吸尘器的具有上游和下游两级旋风的储尘筒, 包括一 容器, 容器中设有脏空气进口和干净空气出口, 所述容器分隔成并列的上游的粗尘室和下 游的细尘室, 粗尘室内设有旋转筒体, 旋转筒体内设有过滤网管, 脏空气进口位于粗尘室 的上侧方, 在旋转筒体内进行大灰尘的粗分离; 而细尘室内设有旋转锥体, 旋转锥体的顶 部为干净空气出口, 在旋转锥体中进行小灰尘的细分离; 过滤网管内通过导向风道与旋转 锥体连通。 上述专利方案仍存在以下不足: 仅有上游粗尘室和下游细尘室两级旋风分离, 下游的细尘室内的旋风转速有限, 实际下游细尘室仅能分离一般小粒径的灰尘, 对超微粉 尘无分离效果, 即尘桶排出的空气仍含有超微粉尘, 会对环境造成二次污染。
发明内容 [0005] 本发明目的是提供一种多筒灰尘分离结构式尘桶, 以解决现有技术对超微粉尘分离 和收集效果差, 造成二次污染的问题。
[0006] 为达到上述目的, 本发明采用的技术方案是: 一种多筒灰尘分离结构式尘桶, 包括 一容器, 该容器上设有脏空气进口和干净空气出口, 脏空气进口沿容器外周切向设置; 所述容器内部中心设有一尘桶内胆;
所述尘桶内胆的中部为一个竖向柱状空腔或绕尘桶内胆的竖向中轴线布置的多个竖向柱状 空腔; 所述竖向柱状空腔分成上部的中间旋风室和下部的集尘腔, 所述中间旋风室外周上 设有沿切向的中间旋风室进风口, 中间旋风室的顶部的中心设中间旋风室出风口; 所述集 尘腔的下端封闭;
所述尘桶内胆的上部的外周设有至少四个外围空心柱, 每个外围空心柱的内腔分成上部的 微尘分离旋风室和下部的集尘室, 微尘分离旋风室的径向尺寸小于所述中间旋风室的径向 尺寸; 所述每个微尘分离旋风室外周上设有沿切向的微尘分离旋风室进风口, 每个微尘分 离旋风室的顶部的中心设微尘分离旋风室出风口; 所述集尘室的下端封闭;
所述尘桶内胆和容器四周内壁之间还设有一网孔罩, 在尘桶内胆和容器四周内壁之间形成 第一级旋风室, 该第一级旋风室经中间旋风室进风口连通中间旋风室, 以此中间旋风室作 为第二级旋风室; 所述中间旋风室出风口与每个微尘分离旋风室进风口连通, 每个微尘分 离旋风室出风口连通所述干净空气出口, 以此所述各微尘分离旋风室作为第三级旋风室。
[0007] 上述方案中, 所述集尘腔的内壁上设有多根竖向的挡筋, 在集尘腔的上部中心还设 有一压灰板, 该压灰板的外围与各挡筋的上端连接, 在压灰板和集尘腔的内壁之间形成供 落灰的缝隙。
[0008] 上述方案中, 所述集尘室的内壁上设有多根竖向的挡筋, 在集尘室的上部中心还设 有一压灰板, 该压灰板的外围与各挡筋的上端连接, 在压灰板和集尘室的内壁之间形成供 落灰的缝隙。 [0009] 上述方案中, 所述中间旋风室出风口向中间旋风室内部延伸有一竖向柱状引导段。
[0010] 上述方案中, 所述各微尘分离旋风室出风口向微尘分离旋风室内部延伸有一竖向柱 状引导段。
[0011] 上述方案中, 所述尘桶内胆的中部为一个沿尘桶内胆的竖向中轴线设置的竖向柱状 空腔; 具体所述尘桶内胆包括一旋风筒顶盖、 一外围旋风筒体、 一中间旋风筒以及一旋风 筒底盖, 所述外围旋风筒体是一环状体, 其上具有所述各个外围空心柱, 各外围空心柱的 上部相连接, 而各外围空心柱的下部间留有通气的间隙; 所述中间旋风筒是一筒状体, 它 装配于外围旋风筒体的中心; 所述旋风筒顶盖封盖外围旋风筒体的上端; 所述旋风筒底盖 主体为一筒状体, 该筒状体的上端口外围设有一圈封板; 所述旋风筒底盖以封板封盖外围 旋风筒体的下端, 使各外围空心柱的下端与封板密封连接; 所述中间旋风筒的下端与所述 封板也密封连接, 以此中间旋风筒的内腔和旋风筒底盖的筒状内腔连通构成所述竖向柱状 空腔。
[0012] 由于上述技术方案运用, 本发明与现有技术相比具有下列优点:
本发明与现有技术相比, 由于特别设计了多个微尘分离旋风室, 在二次旋风分离掉大小灰 尘后, 气流还被分离成多股, 分别进入多个微尘分离旋风室内, 形成第三次高速离心运动, 由于微尘分离旋风室径向尺寸较小, 此时形成的旋风风速非常快, 以将空气中更细微轻质 的超微粉尘分离, 大幅提高了尘桶对超微粉尘的分离效果。 总得来说, 本发明工作时能形 成三次高速离心分离, 并能将不同重量和体积的灰尘分别收集在不同的腔室内, 使灰尘得 到有效的分离和收集, 且在吸尘器的效率和负压等性能上也未造成不利影响, 可以说, 本 发明与现有技术相比有飞跃性改善。

[0018] 具体见图 2、 图 3所示, 具体容器 1包括一筒状容器主体 27、 上盖 28及底盖 29。
[0019] 具体见图 2、 图 3所示, 具体尘桶内胆 3包括一旋风筒顶盖 19、一外围旋风筒体 20、 一中间旋风筒 21以及一旋风筒底盖 22, 所述外围旋风筒体 20是一环状体, 其上具有所述 各个外围空心柱 9, 各外围空心柱 9的上部相连接, 而各外围空心柱 9的下部间留有通气的 间隙。 所述中间旋风筒 21是一筒状体, 它装配于外围旋风筒体 20的中心。 所述旋风筒顶 盖 19封盖外围旋风筒体 20的上端, 且旋风筒顶盖 19的外缘通过第一密封圈 24与容器 1 的周向内壁密封连接。 所述旋风筒底盖 22主体为一筒状体, 该筒状体的上端口外围设有一 圈封板 23 ; 所述旋风筒底盖 22以封板 23封盖外围旋风筒体 20的下端, 使各外围空心柱 9 的下端 (即集尘室 11的下端) 经第二密封圈 25与封板 23密封连接, 中间旋风筒 21的下 端与所述封板 23也经第二密封圈 25密封连接,以此中间旋风筒 21的内腔和旋风筒底盖 22 的筒状内腔连通构成所述竖向柱状空腔 4。 旋风筒底盖 22的下端 (即集尘腔 6的下端) 经 第三密封圈 26与容器 1的底面 (具体如图是底盖 29 ) 密封连接。
[0020] 见图 1-4所示, 所述尘桶内胆 3和容器 1四周内壁之间还设有一网孔罩 14, 在尘桶 内胆 3和容器 1 四周内壁之间形成第一级旋风室, 该第一级旋风室经中间旋风室进风口 7 连通中间旋风室 5, 以此中间旋风室 5作为第二级旋风室; 所述中间旋风室出风口 8与每个 微尘分离旋风室进风口 12连通, 每个微尘分离旋风室出风口 13连通所述干净空气出口, 以此所述各微尘分离旋风室 10作为第三级旋风室。
[0021] 见图 2、 图 3所示, 具体, 所述网孔罩 14的下端口内设有一圈挡圈 30, 所述尘桶内 胆 3的旋风筒底盖 22上的封板 23外缘搁置在挡圈 30之上,使网孔罩 14仅遮挡尘桶内胆 3 的上部。
[0022] 见图 2所示, 所述集尘腔 6的内壁 H ¾" ffi 'J¾向的挡筋 15, 在集尘腔 6的上部中 心还设有一压灰板 16, 该压灰板 16的外围与各挡筋 15的上端连接, 在压灰板 16和集尘腔 6的内壁之间形成供落灰的缝隙 17。 挡筋 15的作用是使集尘腔 6内的气流转速下降, 从而 使掉落在集尘腔 6内的灰尘不会再旋转上升, 而压灰板 16更是起到挡灰作用使灰尘能留在 集尘腔 6内。
[0023] 见图 4所示, 所述集尘室 11的内壁上设有多根竖向的挡筋 15, 在集尘室 11的上部 中心还设有一压灰板 16, 该压灰板 16的外围与各挡筋 15的上端连接, 在压灰板 16与集尘 室 11的内壁之间形成供落灰的缝隙 17。 同样, 此处挡筋 15的作用是使集尘室 11内的气流 转速下降, 从而使掉落在集尘室 11 内的灰尘不会再旋转上升, 而压灰板 16更是起到挡灰 作用使灰尘能留在集尘室 11内。
[0024] 见图 2、 图 3所示, 所述中间旋风室出风口 8向中间旋风室 5内部延伸有一竖向柱 状引导段 18。 所述各微尘分离旋风室出风口 13也向微尘分离旋风室 10内部延伸有一竖向 柱状引导段 18。
[0025] 实际中, 在所述尘桶的上端旋风筒顶盖 19上可再覆盖有一超级过滤器, 即使各微尘 分离旋风室出风口 13经超级过滤器才能通至所述干净空气出口, 超级过滤器由细密海绵和 超级不织棉组成, 用于对出风的进行最后的平面过滤。
[0026] 工作时, 当脏空气经过脏空气进口 2, 沿切向进入容器 1 内, 在离心力的作用下, 灰尘在容器 1 内作离心运动, 大颗粒灰尘或絮状灰尘被甩在容器 1 的内壁上, 带小颗粒的 灰尘的空气通过网孔罩 14的细小孔进入网孔罩 14内, 再经各外围空心柱 9间的间隙、 中 间旋风室进风口 7进入中间旋风室 5, 这样形成第一次旋风, 将大颗粒灰尘或絮状灰尘留在 了容器 1 内底部, 带小颗粒的灰尘的空气进入中间旋风室 5 内。 当带小颗粒的灰尘的空气 沿切向进入中间旋风室 5 中, 即形成第二次旋风, 因为重力的原因, 一般小颗粒的灰尘均 会下落, 通过压灰板 16和集尘腔 6的内壁之间形成供落灰的缝隙 17, 掉落在集尘腔 6内。 同时在该集尘腔 6内的多根挡筋 15能防止 ¾ 腔内的灰尘旋转,保证灰尘不再上浮。 而带有轻质的超微粉尘的空气再通过中间旋风室 5顶部中心的中间旋风室出风口 8通出, 且此时气流被分成多股,分别切向进入周围的多个微尘分离旋风室 10内,形成第三次旋风, 这时的风速非常快, 可以将更细微轻质的超微粉尘在离心力和重力的作用下, 通过压灰板 16和集尘室 11之间的供落灰的缝隙 17, 掉落在集尘室 11 内。 同时在该集尘室 11 内有多 根挡筋 15, 防止掉落在集尘室 11内的粉尘旋转, 保证粉尘不再上浮。 而空气则通过微尘分 离旋风室 10顶部中心的微尘分离旋风室出风口 13进入超级过滤器内, 经超级过滤器过滤 后从干净空气出口进入马达的风罩内。 从上述工作过程可看出, 本实施例通过三次高速离 心分离和一层超级过滤, 将空气中的各类、 各大小、 各重量的灰尘被全部有效的分离和集 中, 保证了马达的高效能的运行, 提高了整机的效率, 防止了细小灰尘的二次环境污染。
[0027] 实施例二: 参见图 6所示:
一种多筒灰尘分离结构式尘桶, 包括一容器 1, 该容器 1上设有脏空气进口 2和干净空气出 口, 脏空气进口 2沿容器 1外周切向设置。 容器 1内部中心设有一尘桶内胆 3。 与实施例一 的不同之处在于: 见图 6所示, 所述尘桶内胆 3的中部的竖向柱状空腔 4为多个, 且这多 个竖向柱状空腔 4绕尘桶内胆 3的竖向中轴线布置, 如图举例为三个竖向柱状空腔 4, 各竖 向柱状空腔 4上的中间旋风室进风口 7位于竖向柱状空腔 4的外侧; 所述外围空心柱 9举 例为 13个, 它们围绕着多个竖向柱状空腔 4的共同的外周布置。
[0028] 其他结构均同实施例一, 具体工作过程也基本与实施例一相同, 这里不再赘述。
[0029] 上述实施例只为说明本发明的技术构思及特点, 其目的在于让熟悉此项技术的人士 能够了解本发明的内容并据以实施, 并不能以此限制本发明的保护范围。 凡根据本发明精 神实质所作的等效变化或修饰, 都应涵盖在本发明的保护范围之内。
