中轴升降式拖把清洗桶以及拖把 技术领域
本实用新型涉及清洁装置技术领域， 尤其是一种中轴升降式拖把清洗桶。 背景技术
传统的拖把清洗桶通常包含并排设置的清洗部和甩干部， 但是这种拖把清 洗桶会占用比较大的空间 （例如中国专利 CN201330360846.2 )。 后来出现了升 降清洗甩干桶解决了占用空间过大的问题， 该清洗升降甩干桶仅需使用一个桶 体和篮子 （例如中国专利 CN201320013544.2)。 通常， 该篮子同轴枢接有支撑 架或者升降轴， 该支撑架或升降轴能够沿该桶体内壁上下移动， 从而， 该篮子 随同该支撑架或升降轴上升后， 放置于该篮子内的拖把头高于桶体内的水平面， 即可进行拖把头的甩干操作， 该篮子随同该支撑架下移后， 放置于该篮子内的 拖把头位于桶体内的水平面之下， 即可进行拖把头的清洗操作。 使用上述拖把 清洗桶时只要沿竖直方向调整篮子的位置， 即可对拖把头进行了清洗和甩干。 但是在清洗拖把的过程中由于篮子的设置会导致拖把头不能完全伸展在水中， 导致拖把头中的泥沙无法充分洗净； 另外现有技术中篮子通常使用轴承套接于 支撑架或者升降轴， 而轴承通常无法密封， 因此在拖把清洗过程中沙子和污水 进入到轴承内部后会造成轴承的生锈和磨损， 影响拖把清洗桶的使用寿命。 实用新型内容

以下通过特定的具体实例说明本实用新型的实施方式， 本领域技术人员可 由本说明书所揭露的内容轻易地了解本实用新型的其他优点与功效。 本实用新 型还可以通过另外不同的具体实施方式加以实施或应用， 本说明书中的各项细 节也可以基于不同观点与应用， 在没有背离本实用新型的精神下进行各种修饰 或改变。
请参阅图 1和图 2，图 1所示为本实用新型中轴升降式拖把清洗桶以及拖把 在第一实施例中的爆炸图， 图 2为本实用新型中轴升降式拖把清洗桶在第一实 施例中清洗拖把时的剖视图。 如图 1或图 2所示， 本实用新型的中轴升降式拖 把清洗桶包括一个桶体 101，在该桶体 101内的底部形成有一凹槽， 该凹槽中组 装有一呈环形的螺纹套 103， 该螺纹套 103通过自攻螺丝固定于所述桶体 101 的底部，于该螺纹套 103的内壁设置有内螺纹，该螺纹套 103用于连接中轴 104。 该中轴 104包括一固定轴 105、 三片中轴插片 106以及一升降轴 107。 该固定轴 105呈圓筒形， 其外侧的底部设置有配合于所述螺纹套 103的外螺纹，该固定轴 105和螺纹套 103通过上述螺纹螺接。 所述固定轴 105的呈圓筒状， 其内壁设置 有卡槽， 内表面设置有凹槽的所述中轴插片 106插设于上述卡槽中。 所述固定 轴 105的内部插设有圓柱状的升降轴 107，该升降轴 107的底部外侧壁上设置有 限位凸块 112。在本实施例中所述限位凸块 112的数量为 3，和所述中轴插片 106 的数目相同。 所述限位凸块 112滑设于所述中轴插片 106的凹槽中。
请继续参阅图 3， 图 3为图 2中的中轴的局部放大图。 如图 1和图 3所示， 在所述升降轴 107的顶部设置有一旋转轴容置部 113;在该旋转容置部 113的底 部容纳有一下轴套 108，该下轴套 108的顶部形成有用于支撑旋转轴 110的凹槽； 在该旋转轴容置部 113的开口处插设有一上轴套 109，该上轴套 109套接于所述 旋转轴 110的中段。 该旋转轴 110的底端抵靠于所述下轴套 108顶部的凹槽， 其另一端穿过所述上轴套 109延伸到所述旋转轴容置部 113的外侧， 在该旋转 轴 110的顶部连接有一拖把头连接件 111。该拖把头连接件 111和所述旋转轴 110 固定连接， 当旋转该拖把头连接件 111 时所述旋转轴 110与其一起旋转。 本实 施例中所述旋转轴 110和所述上轴套 109紧密贴合， 这样可以保持所述旋转轴 容置部 113 的密封状态， 这样在清洗拖把的过程中可以防止污水和泥沙进入该 旋转轴容置部 113的内部而造成所述旋转轴 110的磨损。
如图 1和图 3所示本实用新型的拖把 120包含一个拖把头 121，在该拖把头 121底面的中央设置有一个连接槽，该连接槽周围设有多个下缘内侧带有凸块的 卡爪片 122。 所述拖把 120通过上述连接槽连接于拖把头连接件 111 (此为现有 技术， 故部多加说明）。
请继续参阅图 4及图 5，图 4为本实用新型中轴升降式拖把清洗桶的第一实 施例中固定轴的剖视图； 图 5 为本实用新型中轴升降式拖把清洗桶的第一实施 例中连接于固定轴内壁的轨道展开后的示意图。 如图 1和图 4所示， 本实用新 型的所述固定轴 105的内壁由三块中轴插片 106拼接成， 该中轴插片 106的内 表面预制有凹槽，该中轴插片 106内表面的凹槽拼接成本实施例中所述中轴 104 的轨道。 如图 1、 图 4以及图 5所示， 所述轨道包括一底槽孔 130和一中上槽孔 131， 该底槽孔 130和该中上槽孔 131通过一顶环槽 132连接在一起。 本实施例 中该底槽孔 130和该中上槽孔 131的数目均为三， 并且该底槽孔 130和该中上 槽孔 131等间隔排列。 每个该底槽孔 130和该中上槽孔 131的顶部都设置有一 导向斜面 133，当所述升降轴 107的限位凸块 112从一个槽孔向上运动时该导向 斜面 133会将所述限位凸块 112引导至相邻的槽孔。
如图 1和图 5所示， 本实用新型的中轴升降式拖把桶在使用过程中所述限 位凸块 112滑设于上述轨道中。 由于限位凸块 112刚性连接于所述升降轴 107 外侧的底部， 所以所述升降轴 107 的运动方式也同样的活动范围也受上述轨道 的制约。 若限位凸块 112的初始位置位于所述底槽孔 130底部， 当向上提升所 述升降轴 107时， 该限位凸块 112随所述升降轴 107上升至所述底槽孔 130的 顶端， 随着升降轴 107继续被提升， 该限位凸块 112进入到所述顶环槽 132并 且触碰到位于所述顶环槽 132的上表面、底槽孔 130正上方的所述导向斜面 133， 随后该限位凸块 112在所述导向斜面 133以及所述升降轴 107的作用下向邻近 的所述中上槽孔运 131运动； 此时若释放所述升降轴 107， 所述限位凸块 112会 受所述升降轴 107的驱动沿顶环槽 132运动， 进而落入导向斜面 133指向的中 上槽孔 131中。 若此时再次向上提升限位凸块 112时， 限位凸块 112会沿相似 的方式落入下一个底槽孔 130。
如图 2和图 5所示， 清洗拖把 120时， 首先将所述拖把头 121连接到所述 升降轴 107顶端的所述拖把头连接件 111。若此时所述限位凸块 112位于所述中 上槽孔 131 中， 则需要向上提升所述拖把 120随后放下， 在这个过程中所述升 降轴 107随着所述拖把 120运动， 进而所述限位凸 112会按照前述的运动方式 移动到所述底槽孔 130中， 使得所述拖把 120的位置降低。 如图 2所示， 此时 向所述桶体 101内注水至刚好没过所述拖把头 121，随后转动所述拖把 120即可 清洗所述拖把头 121。 本实施例的拖把清洗桶没有传统设计中承载所述拖把头 121的篮子，这样在清洗所述拖把头 121的过程中所述拖把头 121可以充分和水 接触， 从而提高拖把清洗桶的清洗效果。
请继续参阅图 5和图 6所示， 图 6为本实用新型中轴升降式拖把清洗桶以 及拖把的第一实施例中甩干拖把时的剖视图。 如图 5和图 6所示， 在所述拖把 120清洗完成后向上提升所述拖把 120随后将其放下，在提升所述拖把 120的过 程中连接于所述升降轴 107的所述限位凸块 112从所述底槽孔 130运动到所述 中上槽孔 131。 由于中上槽孔 131 的位置高于底槽孔 130的位置， 因此升降轴 107的顶端以及连接于所述升降轴 107顶端的拖把头 121也向上运动到水面以 上。 随后通过旋转拖把 120即可甩干所述拖把头 121 内多余的水分。 此时将拖 把头 121与拖把头连接件 111分离， 即完成了拖把头 121的清洗及甩干脱水过 程。
请继续参阅图 7和图 8，图 7为本实用新型中轴升降式拖把清洗桶在第二实 施例中中轴升降式拖把清洗桶的爆炸图； 图 8为本实用新型中轴升降式拖把清 洗桶在第一实施例中清洗拖把时的剖视图。 如图 7所示和图 8所示， 在本实施 例中中轴 203包括一固定轴 205、 三片中轴插片 206、 一中轴盖圈 204以及一升 降轴 207。本实施例和第一实施例的主要区别在于在本实施例中升降轴 207和固 定轴 205的连接方式。 所述固定轴 205的底端固定于所述桶体 201内侧的底部， 该固定轴 205的侧边设置有卡槽， 该卡槽用于插设所述中轴插片 206。在本实施 例中所述中轴插片 206的数目为三。 在所述固定轴 205的顶端连接有所述中轴 盖圈 204， 所述中轴盖圈 204可以防止所述中轴插片 206沿所述卡槽滑动。 所述 中轴插片 206的外表面设置有轨道。 在所述固定轴 205的外侧套接有呈圓筒状 的升降轴 207，该升降轴 207内壁的底部设置有所述限位凸块 212，限位凸块 212 滑设于中轴插片 206的轨道中。 当升降轴 207上下移动时， 限位凸块 212会沿 着所述中轴插片 206外侧的轨道运动 。
请继续参阅图 9和图 10， 图 9为本实用新型中轴升降式拖把清洗桶的第二 实施例中桶体以及固定轴的局部剖视图； 图 10为本实用新型中轴升降式拖把清 洗桶在第二实施例中中轴插片展开后的示意图。 如图 9和图 10所示， 所述中轴 插片 206外侧的所述轨道包括底槽孔 230和中上槽孔 231，所述底槽孔 230和所 述中上槽孔 231通过由上升轨道 232、下降轨道 233第一转向轨道 234以及第二 转向轨道 235组成的连接槽连接。 所述上升轨道 232的底端连接于所述底槽孔 230的正上方， 所述下降轨道 233的底端连接于所述底槽孔 230顶部的侧面。 所 述第一转向轨道 234的一端连接于所述上升轨道 232的顶端， 其另一端连接于 所述中上槽孔 231顶部的侧面。 所述第二转向轨道 235的一端连接于所述下降 轨道 233的顶端， 其另一端连接于所述中上槽孔 231的正上方。 在所述下降轨 道的 233的顶端侧面设置有进出缺口 240， 用于限位凸块 212的滑入和滑出。
下面结合图 9和图 10介绍所述限位凸块 212在所述中轴插片 206的轨道内 的运动轨迹。 如图 9和图 10所示： 当进行组装时， 所述限位凸块 212是由所述 进出缺口 240进入所述轨道中并沿着所述下降轨道的 233落入所述底槽孔 230 内， 所以所述限位凸块 212的初始位置位在所述底槽孔 230内， 向上提升所述 升降轴 207，在所述升降轴 207的作用下所述限位凸块 212会向上运动从而进入 位于所述底槽孔 230正上方的所述上升轨道 232，随后所述限位凸块 212继续沿 所述上升轨道 232向上运动。当所述限位凸块 212运动到所述第一转向轨道 234 的内部后继续向上运动， 所述限位凸块 212到达第一转向轨道 234的最高点时 即无法再向上移动， 随后所述限位凸块 212在所述第一转向轨道 234的作用下 移动， 进而从所述中上槽孔 231侧面的顶部滑入所述中上槽孔 231， 若此时没有 外力提升所述升降轴 207则所述限位凸 212会向下落入所述中上槽孔 231的底 部。 至此所述限位凸块 212完成了从所述底槽孔 230向所述中上槽孔 231的上 升过程。
所述限位凸块 212的下降过程和其上升过程类似： 当所述限位凸块 212位 于所述中上槽孔 231底部时向上提升所述升降轴 207，在所述升降轴 207的带动 下所述限位凸块 212向上运动进入连接于所述中上槽孔 231正上方的所述第二 转向轨道 235，当所述限位凸块 212到达所述第二转向轨道 235的最高点时即无 法再向上移动， 随后所述限位凸块 212在所述第二转向轨道 235的作用下移动 从而进入所述下降轨道 233;随后所述限位凸块 212沿着所述下降轨道 233向下 运动， 最后从所述底槽孔 230顶部的侧面滑入所述底槽孔 230的底部。
如果在所述限位凸块 212沿所述下降轨道 233的下降过程中向上提升所述 升降轴 207，那么所述限位凸块 212会从位于所述下降轨道的 233的顶端侧面的 所述进出缺口 240滑出， 由于所述升降轴 207通过固定连接于其内壁的所述限 位凸快 212滑动连接于所述固定轴 205，所以所述限位凸块 212滑出后所述固定 轴 205便和升降轴 207分离。 所述进出缺口 240的设置使得所述升降轴 207可 拆卸的连接于所述升降轴 205，这样在使用过程中不用特殊工具也可以将所述升 降轴 207拆除以便清洗所述升降轴 207以及所述升降轴 205。
如图 7和图 8所示： 本实施例和第一实施例类似， 本实施例的所述升降轴 207的顶部也连接有所述旋转轴 210， 所述旋转轴 210通过所述上轴套 209和所 述下轴套 208安装于所述升降轴 207顶部的所述旋转轴容置部中。 在所述旋转 轴 210的顶端连接有所述拖把头连接件 211。
请继续参阅图 11，图 11为本实用新型中轴升降式拖把清洗桶的第三实施例 中的爆炸图； 如图 11所示， 在本实施例中中轴 303主要包括一固定轴 305、 三 片中轴插片 306以及一升降轴 307。 所述固定轴 305的底端固定于所述桶体 301 内侧的底部， 所述固定轴 305外侧的顶部连接有 3个限位凸块 312。本实施例中 所述升降轴 307呈圓筒状， 其内壁设置有卡槽， 该卡槽用于插设所述中轴插片 306。 在本实施例中所述中轴插片 306的数目为三。 所述中轴插片 306的内表面 设置有轨道。 所述升降轴 307套接于所述固定轴 305的外侧。 连接于所述固定 轴 305的所述限位凸块 312滑设于所述中轴插片 306的轨道中。 当所述升降轴 307上下移动时，所述限位凸块 312会沿着所述中轴插片 306内表面的所述轨道 运动 。
请继续参阅图 12和图 13， 图 12为本实用新型中轴升降式拖把清洗桶的第 三实施例中中轴的局剖视图； 图 13所示为本实用新型在第三实施例中中轴插片 306外侧的轨道展开后的示意图。如图 12和图 13所示， 所述中轴插片 306内侧 的所述轨道包括底槽孔 330和中上槽孔 331， 所述底槽孔 330和所述中上槽孔 331通过由上升轨道 332、下降轨道 333第一转向轨道 334以及第二转向轨道 335 组成的连接槽连接。 所述上升轨道 332的顶端连接于所述中上槽孔 331底部的 侧面， 所述下降轨道 333的顶端连接于所述中上槽孔 331的正下方。 所述第一 转向轨道 334的一端连接于所述上升轨道 332的底端， 其另一端连接于所述底 槽孔 330底部的侧面。 所述第二转向轨道 335的一端连接于所述下降轨道 333 的底端， 其另一端连接于所述底槽孔 330底部的侧面。 在所述上升轨道的 332 的底端侧面设置有一进出缺口 340， 用于所述限位凸块 312的滑入和滑出。 下面结合图 12和图 13介绍所述限位凸块 312在所述中轴插片 306的轨道 内的运动轨迹。 如图 12和图 13所示： 当进行组装时， 所述限位凸块 312是由 所述进出缺口 340进入所述轨道中并沿着所述上升轨道的 332上升至所述中上 槽孔 331 内， 所以所述限位凸块 312的初始位置位在所述中上槽孔 331 内， 向 上提升所述升降轴 307，在所述升降轴 307的作用下所述限位凸块 312会相对所 述轨道向下运动从而进入位于所述中上槽孔 331正下方的所述下降轨道 333，随 后所述限位凸块 312继续沿所述下降轨道 333向下运动。 当所述限位凸块 312 运动到所述第二转向轨道 335的内部后继续向下运动， 所述限位凸块 312到达 第二转向轨道 335的最低点时即无法再向下移动， 随后所述限位凸块 312在所 述第二转向轨道 335的最低点处向上移动， 进而从所述底槽孔 330底部的侧面 滑入所述底槽孔 330， 若此时没有外力提升所述升降轴 307 则所述限位凸 312 会向相对所述轨道上升进而抵靠于所述底槽孔 330的顶部。 至此所述限位凸块 所述限位凸块 312的上升过程和其下降过程类似： 当所述限位凸块 312位 于所述底槽孔 330顶部时向上提升所述升降轴 307，所述限位凸块 312相对于所 述轨道向下运动进入连接于所述底槽孔 330正下方的所述第一转向轨道 334，当 所述限位凸块 312到达所述第一转向轨道 334的最低点时即无法再向下移动， 随后所述限位凸块 312在所述第一转向轨道 334的作用下向上移动从而进入所 述上升轨道 332; 随后所述限位凸块 312沿着所述上升轨道 332向上运动， 最后 从所述中上槽孔 331底部的侧面滑入所述中上槽孔 330。
如果在所述限位凸块 312沿所述上升轨道 332的上升过程中向上提升所述 升降轴 307，那么所述限位凸块 312会相对所述轨道向下运动， 进而从位于所述 上升轨道的 332的底端侧面的所述进出缺口 340滑出， 由于所述固定轴 305通 过固定连接于其顶部的所述限位凸快 312滑动连接于所述升降轴 307，所以所述 限位凸块 312滑出后所述固定轴 305便和升降轴 307分离。
如图 11 所示： 本实施例和第一实施例类似， 本实施例的所述升降轴 307 的顶部也安装有所述旋转轴 310，所述旋转轴 310通过所述上轴套 309和所述下 轴套 308安装于所述升降轴 307顶部的所述旋转轴容置部中。在所述旋转轴 310 的顶端连接有所述拖把头连接件 311。
以上所述仅是本实用新型的较佳实施例而已， 并非对本实用新型做任何形 式上的限制， 虽然本实用新型已以较佳实施例揭露如上， 然而并非用以限定本 实用新型， 任何熟悉本专业的技术人员， 在不脱离本实用新型技术方案的范围 内， 当可利用上述揭示的技术内容作出些许更动或修饰为等同变化的等效实施 例， 但凡是未脱离本实用新型技术方案的内容， 依据本实用新型的技术实质对 以上实施例所作的任何简单修改、 等同变化与修饰， 均仍属于本实用新型技术 方案的范围内。
