Description

一种液体泵装置
技术领域
本发明涉及一种液体泵装置。 背景技术
液体泵装置一般是安装在容器的开口处, 用于通过使用者的手动按压 操作将容器内的液体产品泵送分配出容器以供使用。 常见的液体泵装置是 通过活塞杆上下运动, 将液体从容器中抽出, 从而通过出口部排出。 如图 1 所示, 在使用者向下按压泵压头的过程中, 下单向阀 180关闭, 上单向阀 140 (该单向阀由活塞杆 152的一外周面 (作为阀座)和安装在该外周面上的 活塞 141 (作为阀件)构成)打开, 汽缸 160中的储液槽 130内的液体产品通 过打开的上单向阀 140、 并通过活塞 150 (该活塞由活塞杆 152和安装在活 塞杆 152上的活塞件 141构成, 其中活塞杆 152和活塞件 141同时用作构 成单向阀 140和活塞 150的构件, 即单向阀 140是作为活塞 150的一部分 而提供的)的输送通道 151和压头 110的排出通道 111被泵送出, 该输送通 道 151和排出通道 111构成液体产品从储液槽 130泵送分配到容器外部的 分配通道; 当使用者撤去对压头 110的向下按压作用后, 压头 110在弹性 复位装置 120的作用下回复其原来位置, 且在压头 110的复位过程中, 下 单向阀 180打开, 上单向阀 140关闭, 容器内的液体产品通过打开的下单 向阀 180抽吸到储液槽 130内以供下次泵送分配。 通常, 分配通道位于上 单向阀 140和压头 110的出口部 112之间。
这种液体泵装置的设计存在一个缺点。 具体说, 在液体泵的每次按压 泵送分配操作完成之后, 压头的出口部都会残留有液体产品, 该残留的液 体产品会滴落到放置容器的表面上或容器本身之上, 尤其是在挪动或放置 容器的过程中。 对于粘性低、 流动性较好的液体产品(例如油状或水状产 品), 即使容器不挪动而不产生震动, 放置一段时间后靠近压头出口部的残 留液体产品也会在重力的作用下自行滴下, 造成不希望有的污染问题。 还有另一种按压式液体泵装置, 它包括压头、 与压头连接的活塞、 上 单向阀、 储液槽以及安装在储液槽底部的下单向阀。 压头和活塞共同形成 液体产品的分配通道。 该液体泵包括用于在压头被向下按压的过程中减小 分配通道的容积、 同时在撤去向下按压作用后使分配通道的容积恢复原态 的容积变化装置。 利用本实用新型的具有分配通道容积变化装置的液体泵, 可有效避免分配通道内的残留液体产品从压头出口部的滴漏。 但是该液体 泵装置结构复杂, 且容器内所储存的液体无法避免与外界接触, 使液体受 到污染, 且液体实际使用率不高。
另外, 上述两种液体泵装置, 结构复杂, 采用塑料、 玻璃、 金属等材 料, 拆解难度高, 产品报废后,一般采用掩埋的方式, 对环境危害极高。
由此, 急需一种新型的液体泵装置。

当本发明被安装在容器上, 由于采用整体相对密封的设计, 通过软胶 按压装置的按压及恢复产生的吸力, 将液体输送分配到容器外, 并且能够 避免容器内存储的液体与外接接触而受到污染, 且采用隐形出料口, 只有 当使用时, 容器内所存储的液体被挤出隐形出料口, 从而保证未被使用的 液体没有与外接接触, 并且液体没有直接存储在容器中, 而是通过软性密 封囊受到保护。 在所述导料管的管壁上设置有至少一个通孔, 实现对所存 储的液体的最大实际使用率, 结构简单, 成本低廉, 而且产品容易拆解, 方便报废后的处理, 避免对环境的危害, 环保无污染。
应当理解的是, 对本领域普通技术人员来说, 可以根据上述说明加以 改进或变换, 而所有这些改进和变换都应属于本发明所附权利要求的保护 范围。
上面结合附图对本发明专利进行了示例性的描述, 显然本发明专利的 实现并不受上述方式的限制, 只要采用了本发明专利的方法构思和技术方 案进行的各种改进, 或未经改进将本发明专利的构思和技术方案直接应用 于其它场合的, 均在本发明的保护范围内。
