通过采用上述技术方案，在对活塞体施力以压缩抽料腔室后，松开外部对活塞体的施力，则活塞体能够在弹性件的作用下回位，从而增大抽料腔室的空间，使抽料腔室内形成负压。
第二方面，本申请提供一种泵芯。
一种泵芯，包括上述泵头，以及与所述泵头密封连接的罐体，所述罐体内密封滑移设置有活塞件，所述罐体一端为进气口，另一端为出料口，所述活塞件位于所述进气口和出料口之间，所述出料口与所述活塞件之间用于填设物料，所述出料口设有与所述单向进料阀片配合实现向所述抽料腔室单向输送物料的阻挡件。
通过采用上述技术方案，罐体内物料的输出也是采用负压挤出的原理，即，与罐体连通的抽料腔室内才形成负压从罐体内吸取物料，从而使罐体内形成负压，继而外部大气压推动活塞件移动，继而实现物料从罐体向抽料腔室内的泵送。
在一些实施方式中，所述阻挡件包括位于所述出料口开口区域内的阻挡片，以及连接所述阻挡片与所述出料口边沿的连接臂，所述阻挡片与所述出料口之间留有过料间隙，在所述罐体与所述泵头安装连接后，所述阻挡片能够与所述刚性部抵紧配合，且阻挡片完全封闭所述刚性部的内孔，所述单向进料阀片受力后，所述变形部能够形变以使所述刚性部脱离与所述阻挡片抵触。
通过采用上述技术方案，罐体出料口处的阻挡件与单向进料阀片配合，单向进料阀片由于变形部的设置能够实现其受力后的浮动，在抽料腔室内形成负压后向会形成向抽料腔室内腔的吸力，因此，与抽料腔室连通的罐体内的物料在负压吸力的作用下挤压单向进料阀片，使变形部形变以使刚性部脱离与所述阻挡片抵触，从而使物料进入抽料腔室内；而在再次压缩抽料腔室时，单向进料阀片受抽料腔室内物料的挤压，与罐体出料口处的阻挡件紧紧贴合，从而使物料仅能够从活塞体的出料孔泵出。
第三方面，本申请提供一种掌压式积木泵罐。
一种掌压式积木泵罐，包括上述泵芯，以及与所述泵芯配合安装的外壳体，所述泵芯位于所述外壳体内部，另外设有与所述外壳体直线滑移配合的泵盖，所述泵盖与所述压盖连接，且泵盖设有与所述抽料腔室连通的泵出通道。
通过采用上述技术方案，提供了一种组装式的泵罐，其不仅能够实现物料的快速泵出，并可根据设计需求单独制造与泵芯适配的外壳体与泵芯组装，其组装形式类似于搭积木，从而实现了泵罐外形的多样性；另外，泵盖与外壳体直线滑移配合，因此，掌压式的直线施力即可实现抽料腔室的压缩，因此，操作更加省力。

具体实施方式
以下结合附图1-10对本申请作进一步详细说明。
本申请实施例公开了一种泵头，如图1所示，其包括泵壳1、位于泵壳1内的泵料组件2，和穿过泵壳1与泵料组件2配合的压盖3。如图2和图3所示，泵壳1为一端开口另一端闭口设置的柱状壳体；泵料组件2主要由分隔支座5和位于分隔支座5内且与分隔支座5滑移配合的活塞体22组成，分隔支座5包括同轴套设的外筒体51及内筒体52，内筒体52和外筒体51于一端端部相互连接成一体，或两者一体成型，在本申请此实施方式中，我们定义分隔支座5以其轴向竖直设置，且内筒体52和外筒体51相互连接的一端朝下，如图3所示，外筒体51的顶端端部与泵壳1内壁卡嵌配合，且外筒体51与泵壳1内壁之间形成有间隙；内筒体52内周壁滑动密封配合上述活塞体22；且活塞体22相对内筒体52的滑动方向位位于内筒体52轴线方向上；内筒体52底端向内缩径形成单向进料阀片6，单向进料阀片6的中心为进料孔，活塞体22上沿其相对内筒体52的滑移方向贯通有出料孔221，出料孔221和进料孔正对设置，出料孔221内安装有单向出料阀件7，单向进料阀片6与活塞体22之间的空间为抽料腔室21，通过单向进料阀片6及单向出料阀件7实现抽料腔室21与外界的单向连通；压盖3穿过泵壳1闭口端以与活塞体22连接安装，且压盖3贯穿有与出料孔221连通的出料通道31，压盖3和分隔支座5之间还安装有弹性件8，弹性件8的两端分 别与压盖3和分隔支座5抵触。
如图4所示，单向进料阀片6成环形，包括成环形的变形部61及成环形的刚性部62，变形部61截面为波浪状，具有一定的弹性，刚性部62为硬质件，刚性部62位于变形部61内环，变形部61位于内筒体52的内环，刚性部62、变形部61及内筒体52三者一体注塑成型。
如图5所示，单向出料阀件7包括：与活塞体22配合安装的安装部71、与安装部71相对设置的阀片72，以及连接安装部71与阀片72的若干个变形支臂73，安装部71成圆环状，阀片72成圆饼状，两者同轴设置，且两者之间在轴向上形成有间隙，变形支臂73圆周阵列于安装部71与阀片72之间。每个变形支臂73由至少2段支臂部731组成，且至少有2段支臂部731不同轴，因此，能够便于变形支臂73在受力时发生弹性形变。
如图5和图6所示，活塞体22上的出料孔221内部内缩形成有安装台阶2212，且出料孔221远离单向进料阀片6的一端内径大于其另一端的内径，单向出料阀件7安装于出料孔221内，且通过安装部71与安装台阶2212抵紧配合。出料孔221靠近单向进料阀片6的一端端口再次内缩形成抵接面2211，单向出料阀件7安装于出料孔221内至安装部71与安装台阶2212抵紧配合时，在阀片72处于非受力状态下时，阀片72与抵接面2211抵紧配合，且在阀片72与抵接面2211抵紧配合时，阀片72完全封闭出料孔221。
本申请还公开了一种泵芯，如图7和图8所示，包括上述泵头301及一与泵头301密封连接的罐体9，结合图9所示，罐体9内密封滑移设置有活塞件91，罐体9一端为进气口901，另一端为出料口902，活塞件91位于进气口901和出料口902之间，出料口902与活塞件91之间用于填设物料，出料口902处成型有与单向进料阀片6配合实现向抽料腔室21单向输送物料的阻挡件92。
如图7和图9所示，阻挡件92包括位于出料口902开口区域内的阻挡片921，以及连接阻挡片921与出料口902边沿的连接臂903，阻挡片921位于出料口902中心位置，且阻挡片921与出料口902之间留有过料间隙904，连接臂903圆周阵列于过料间隙904内。另外，在罐体9与泵头301安装连接后，阻挡片921能够与刚性部62抵紧配合，且阻挡片921完全封闭刚性部62的内孔，而在单向进料阀片6受力后，变形部61能够形变以使刚性部62脱离与阻挡片921抵触。因此，罐体9出料口902处的阻挡件92与单向进料阀片6配合，单向进料阀片6由于变形部61的设置能够实现其受力后的浮动，在抽料腔室21内形成负压后向会形成向抽料腔室21内腔的吸力，因此，与抽料腔室21连通的罐体9内的物料在负压吸力的作用下挤压单向进料阀片6，使变形部61形变以使刚性部62脱离与阻挡片921 抵触，从而使物料进入抽料腔室21内；而在再次压缩抽料腔室21时，单向进料阀片6受抽料腔室21内物料的挤压，与罐体9出料口902处的阻挡件92紧紧贴合，从而使物料仅能够从活塞体22的出料孔221泵出。
另外，如图9所示，在泵头301的的泵壳1的内壁成型有内螺纹，且内螺纹位于外筒体51与泵壳1之间形成的间隙内；罐体9位于出料口902的一端沿其轴线延伸形成连接管段93，连接管段93的外壁成型有与上述内螺纹配合的外螺纹，且连接管段93能够与外筒体51与泵壳1之间形成的间隙嵌合，因此，在连接泵头301与罐体9时，将连接管段93对准外筒体51与泵壳1之间形成的间隙位置后旋进即可。
在泵头301和罐体9连接后，泵头301内分隔支座5的底面与罐体9出料口902的端面贴合设置，为了更好的实现泵头301与罐体9间的密封连接，分隔支座5的底面与罐体9出料口902的端面之间形成迷宫密封结构94。
本申请还公开了一种掌压式积木泵罐，如图10所示，包括上述泵芯30，以及与上述泵芯30配合安装的外壳体10，外壳体10为两端贯通的筒体结构，且外壳体10一端向内完成形成卡边101，外壳体10套设于泵芯30外部，卡边101夹持于泵头301和罐体9之间。因此，在安装泵芯30和外壳体10时候，首先将泵头301从外壳体10的一端插入外壳体10内，直至泵头301与卡边抵紧，然后从外壳体10的另一端插入罐体9，并使罐体9与泵头301螺纹旋紧，从而使卡边101夹持于泵头301和罐体9之间，实现外壳体10与泵芯30的安装固定。
如图8至图10所示，为了在安装时更旋转罐体9，在罐体9的进气口901一端还卡嵌有握持部9011，握持部9011上开设进气孔9012，握持部9011与罐体9周向定位连接，握持部9011朝向罐体9外部的一侧端面设有便于捏取的捏取块9013，因此，可通过捏紧捏取块9013旋转罐体9；另外，泵壳1与外壳体10之间也通过卡嵌的方式实现在周向上的定位卡接，并且泵壳1远离罐体9的一端伸出于外壳体10外，从而确保在旋转罐体9时泵头301相对外壳体10保持固定，因此只需握持外壳体10即可，从而使安装过程更加便捷。
如图10所示，还设有与外壳体10在外壳体10轴线方向上直线滑移配合的泵盖20，泵盖20与压盖3嵌设连接，且泵盖20设有与抽料腔室21连通的泵出通道201。
以上均为本申请的较佳实施例，并非依此限制本申请的保护范围，故：凡依本申请的结构、形状、原理所做的等效变化，均应涵盖于本申请的保护范围之内。
