Description

柱塞泵以及带有该柱塞泵的水净化装置 技术领域
本发明涉及一种柱塞泵。 本发明还涉及带有柱塞泵的水净化装置。 背景技术
柱塞泵是通过操纵摇杆带动柱塞泵的活塞进行往复运动, 从而对 流体进行压缩来产生压缩的流体。
通常使用的柱塞泵, 摇杆与柱塞泵的活塞后端连接。 典型地, 在 活塞的端部形成一个铰接部, 摇杆通过销轴与活塞的端部进行连接, 这样就可以将驱动动力传输到柱塞泵的活塞上。
例如, 图 5 中示出了一个典型地双活塞柱塞泵, 其包括两个活塞 和缸筒, 摇杆的一端与动力输入机构 (或者手柄) 相连, 而摇杆上设 置了两个孔, 通过两个销子分别与柱塞泵的两个活塞铰接, 而在摇杆 的两个孔之间设置有销轴。 通过动力输入机构的摆动, 两个柱塞泵交 替地进行工作, 从而不断地压缩流体。 根据上述结构, 摇杆需要 2个 铰接部和 2个销轴分别与活塞的端部进行铰接。 因此, 现有的结构需 要的部件数目较多, 要求的空间较大, 并且也导致了柱塞泵本身的体 积和重量的增加。
一般使用铰接结构的柱塞泵的活塞直径都在 14毫米以上, 而要在 10-12毫米的活塞采用铰接结构, 从制造和装配来说就有一定难度。
现有的便携式水净化设备, 需要使用柱塞泵尤其是手动柱塞泵作 为压力的来源。 而这种便携式水净化设备需要方便携带, 因此对体积 和重量的要求很严格, 需要尽可能地减小设备的体积和重量。
有些便携式水净化设备要求随身携带, 体积和重量都很小, 柱塞 泵的直径有时要求在 10毫米以下。而在这种设备中使用铰接结构对动 力输入机构和活塞进行连接, 无论是在制造工艺、 装配以及生产成本 都有较高要求。 因此, 如何设计出体积小、 重量轻并且效率高的产品 是设计者面临的重要议题。 发明内容
鉴于上述现有技术的缺点, 本发明所要解决的技术问题是提供一 种新颖的柱塞泵, 其具有结构简单、 安装方便、 减少体积和重量的特 点。
本发明所要解决的另外的技术问题是提供一种新颖的便携式水净 化设备, 其装配有上述新颖的柱塞泵。
为了解决上述技术问题, 根据本发明的第一方面, 一种柱塞泵, 包括: 泵体, 该泵体设置有缸筒; 活塞, 该活塞的一端安装在缸筒内; 摇杆, 该摇杆提供活塞往复运动的驱动力, 并且能够枢转地安装在泵 体上; 所述活塞包括有伸出缸筒外部的伸出部分, 在该伸出部分上设 置有槽, 该槽在活塞轴向两个内侧设置有 V型突起, 该 V型突起的表 面由两个从活塞外周向内倾斜的平面构成, 该两个平面相交而形成的 棱线与活塞的轴线垂直; 所述摇杆插入该槽中。
上述方案中的 "从活塞外周向内倾斜" 中的 "内" 是指相对于外 周的内侧。
根据本发明的第二方面, 所述摇杆通过销轴安装在泵体上。
根据本发明的第三方面, 所述柱塞泵为包括两个缸筒和活塞的双 柱塞泵。
根据本发明的第四方面, 所述销轴设置两个活塞中间。
根据本发明的第五方面, 所述 V型突起为非对称 V型。
根据本发明的第六方面, 所述非对称的 V型突起棱线位于距活塞 外周 1/3直径位置。
根据本发明的第七方面, 所述活塞和摇杆为不锈钢、 钛合金、 铝 合金或者工程塑料制成。
根据本发明的第八方面, 所述柱塞泵为手动柱塞泵。
根据本发明的第九方面, 所述柱塞泵为包括两个缸筒和活塞的手 动双柱塞泵, 所述摇杆通过设置两个活塞中间的销轴安装在泵体上, 所述 V型突起为非对称 V型,所述非对称的 V型突起棱线位于距活塞 外周 1/3直径位置, 所述活塞和摇杆为不锈钢、钛合金、铝合金或者工 程塑料制成。 根据本发明的第十方面, 本发明还提供了一种水净化装置, 其包 括上述本发明的第一至第九方面中任一所述的柱塞泵。
本发明的有益效果; 本发明采用了在活塞开槽并且设置 V型突起 的结构, 并且通过将摇杆插入活塞的槽中而可以将动力输入到活塞, 从而避免了使用传统的铰接结构, 由此减少了连接部件的数目, 减少 了体积和空间。

下面结合附图 1-3对本发明示例性实施例的柱塞泵进行详细说明。 本发明示例性实施例的柱塞泵为手动双柱塞泵。 该柱塞泵包括泵 体 1, 泵体 1上设置有两个柱塞泵的缸筒、 进水通道 (未示出)、 出水 通道以及单向阀。其中活塞分别是第一活塞 5和第二活塞 6; 两个活塞 分别安装在各自的柱塞泵缸筒中。
柱塞泵的活塞 5、 6一端安装有密封件并且安装到柱塞泵的缸筒中 以用于对水进行压缩,被压缩的水沿着出水通道由单向阀排出;活塞 5、 6的另一端从缸筒伸出。 所述活塞 5、 6包括有伸出缸筒外部的伸出部 分, 该伸出部分在活塞 5、 6的压缩冲程也不会进入到缸筒中。活塞 5、 6伸出部分分别设置有第一槽 7和第二槽 8, 这些槽 7、 8沿着活塞 5、 6的轴向延伸, 优选该槽 7、 8相对于穿过活塞直径的中心平面对称。 为了节约空间, 该槽 7、 8优选地设置靠近伸出部分的端部。
在该槽 7、 8内沿轴向的上、 下两侧分别设置有向内突出的 V型突 起, 即上 V型突起 9和下 V型突起 10 (参见图 2)。 该 V型突起 9、 10的表面是两个从活塞 5、 6的外周向活塞内侧倾斜的平面, 两个平面 相交形成一个棱线。 优选地, 该棱线与活塞的轴线垂直 (也与槽的中 心平面垂直), 即该棱线不是与槽平面的平行的方向延伸。
摇杆 2—端与手柄 3相连, 并且摇杆 2穿过两个活塞 5、 6的槽 7、 8。该摇杆 2上设置有孔,销轴 4穿过该孔而将摇杆 2铰接在泵体 1上。 虽然本实施例中使用销轴 4对摇杆 2进行铰接, 但是也可以使用其他 可以使摇杆 2相对于泵体 1转动结构。 该销轴 2设置在两个活塞 5、 6 之间, 优选为活塞 5、 6之间的中间位置, 从而使摇杆 2对于两个活塞 5、 6的力臂是相等的。 通过提升和下压手柄 3而带动摇杆 2逆时针和 顺时针摆动, 从而带动两个柱塞泵活塞 5、 6往复运动。
在图 1-3中示出的实施例中, V型突起为不对称 V型。 也就是说, 该 V字由两个相交的斜线构成, 即 V型突起为两个斜面构成; 如果将 两个柱塞泵之间距离较近的一侧称之为内侧, 而将两个柱塞泵之间距 离较远的一侧称之为外侧, 则靠近活塞 5、 6外侧的斜线短于活塞内侧 的斜线, 也就是说, 该 V型的顶点不是位于穿过活塞 5、 6直径的平面 上, 而是与其平行的平面。 即 V型槽棱线与活塞 5、 6的直径不重合。
图 4中示出了不对称 V型突起(a)与对称 V型(b) 的比较视图。 虽然本发明实施例中示出的是不对称 V型突起的外侧边短于内侧边, 但是也可以根据需要进行变化, 例如可以使 V型突起的外侧边长于内 侧边, 这种变化同样落入本发明的保护范围内。
虽然在本实施例中销轴 4两侧的摇杆 2长度基本上相等; 但是该 两侧的摇杆 2长度也可以是不相等的。
优选, 从外侧测量, 该棱线位于直径 1/3处。 例如活塞直径为 10 毫米, 那么棱线位于距离活塞外侧的周边 3.3毫米处。
由于摇杆 2通过作用在 V型槽的斜面上而使活塞 5、 6运动, 因此 会对活塞 5、 6产生径向的分力; 如果该棱线向外偏离中心太多, 则活 塞侧面与缸筒之间的摩擦力会变得较大的, 会增大驱动时的摩擦阻力。
活塞 5、 6和摇杆 2的材料可选用但不限于不锈钢、 钛合金、 铝合 金、 工程塑料等等; 其制造方法可选用但不限于浇铸、 压铸、 注塑、 机加工等等。 优选地, 活塞的材料为工程塑料; 而摇杆因受力优选为 不锈钢。 工程塑料和不锈钢之间的摩擦力较小, 因此可以减少相互之 间的阻力并且工程塑料有自润滑的特点而可以解决润滑的问题。
虽然本发明结合了具有两个柱塞泵的实施例进行了说明, 但是本 发明还可以用于其他数目的柱塞泵, 例如 1个或者 4个等等。 其也可 以用于其他类型的泵, 而不限于柱塞泵。
在用于一个柱塞泵的时候,可以将图 1-3中示出的两个柱塞泵中的 任一个删除即可。 即销轴位于活塞的外侧 (可以为内侧和外侧), 而摇 杆穿过活塞。
当用于 4 个柱塞泵时, 可以为每两个柱塞泵设置一个摇杆, 然后 将摇杆的端部用连杆连接在一起, 连杆再与手柄连接。 这样手柄就可 以带动 4个柱塞泵一起运动。
下面结合附图说明本发明的柱塞泵的操作过程。
如图 1所示, 当手柄 3下压的时候, 手柄 3带动摇杆 2顺时针转 动, 由此使柱塞泵第一活塞 5 向上运动而压缩缸筒内的水, 同时柱塞 泵第二活塞 6向下运动而将水吸入缸筒内; 此时, 两个活塞 5、 6的 V 型槽 9、 10外侧部分 (V字形的短边) 受力; 当摇杆达到图 1中的手 柄 3下止点位置的时候, 手柄 3停止下压动作, 第一活塞 5的行程也 达到其最高点, 而第二活塞 6的行程也达到其最低点。
图 2示出了摇杆 2位于中间位置的状态。
然后继续操作手柄 3向上运动, 手柄 3带动摇杆 2逆时针转动, 由此使柱塞泵第二活塞 6 向上运动而压缩缸筒内的水, 同时柱塞泵第 一活塞 5向下运动而将水吸入缸筒内, 如图 3所示; 此时, 两个活塞 的 V型槽 9、 10内侧部分 (V字形的长边) 受力; 当摇杆 2达到图 2 中的手柄 3上止点位置的时候, 手柄 3停止向上的动作, 第二活塞 10 的行程也达到其最高点, 而第一活塞 9的行程也达到其最低点。
虽然上面说明书以手动柱塞泵为例进行了说明, 但是本发明的结 构不仅限于手动柱塞泵, 也可以使用电力、 液压或者其他动力带动的 柱塞泵, 仅是将由手柄输入的动力改为其他的动力部件输入, 例如将 实施例中手柄改为有电机带动偏心轮从而实现往复运动的机构, 其结 构对于本领域技术人员来说是显而易见的, 在此就不做过多的描述; 而其原理没有任何变化。 因此其也落入本发明的保护范围。
下面结合图 6说明配备了本发明柱塞泵的便携式水净化装置。 该便携式水净化装置包括有前端泵体部分、 中间膜管和滤芯部分 和后端卸荷排污部分。 中间膜管和滤芯部分分别与前端泵体部分和后 端卸荷排污部分用螺紋连接。
泵体部分包括有进水和出水单向阀、 柱塞泵、 摆杆和手柄。 通过 摇动摆杆而带动手柄使柱塞泵进行往复运动而吸入待净化的水, 并且 将该水加压后排出泵体, 进入到中间膜管和滤芯部分。
在中间膜管和膜芯滤芯部分, 待净化的水通过反渗透而生成符合 要求的淡水, 多余的浓污水排出到后端卸荷排污部分。
在后端卸荷排污部分, 淡水从淡水管排出, 而浓污水从污水管排 出。
上面结合附图对本发明进行了示例性描述, 显然本发明的具体实 现并不受上述方式的限制, 只要采用了本发明的方法构思和技术方案 进行的各种改进, 或者未经改进将本发明的构思和技术方案直接应用 于其他场合的, 均在本发明的保护范围之内。
