Description

改进型泵芯及其环保高新材料制备方法 技术领域
本发明涉及乳液泵和真空泵的泵芯，是一种改进型泵芯及其环保高新材料制备方法。
 背景技术
乳液瓶和真空泵是一种用于乳液存取的容器，其主要利用按压式微型喷雾器的原理，并在头帽内省略挡片的设置，从而使乳液经过吸管、泵体后，从喷头的头帽流出，而不会由于挡片的阻挡而雾化喷出。两则的区别主要在于泵体的一侧是否设有通孔，以及是否设有吸管；此类乳液瓶和真空泵的主体结构为乳液瓶盖，以及泵芯，其中一些泵芯采用外置弹簧的结构，便于其作为共用件使用和自动化生产装配。如中国专利文献中披露的申请号201510489564.0，申请公布日2015.11.11，发明名称“弹簧外置式泵芯及其使用方法”；但上述泵芯的弹簧密闭依赖于具体应用时的大圈和头帽结构设计，弹簧较难在泵芯组立中独立密闭，弹簧稳定性欠佳，泵芯组立中的弹簧外置情况，使其作为共用件应用于同类产品的自动化装配生产容易受到设备影响。
 技术问题
为克服上述不足，本发明的目的是向本领域提供一种用于真空泵或乳液泵的改进型泵芯及其环保高新材料制备方法，使其解决现有同类产品较难用于自动化装配生产，生产制备的原材料环保性、刚性欠佳的技术问题。其目的是通过如下技术方案实现的。
 技术解决方案
一种改进型泵芯，该泵芯的泵体内设有弹套、阀针、活塞，弹套设置于泵体内的吸管端槽孔内，活塞套入设置于阀针的钉部外径，活塞的外径与泵体的内壁相抵密封，阀针的钉部末端处钉圈槽外径与阀杆内的扣圈筋扣合，泵体外侧的阀杆外径与泵体外侧的内塞之间设有弹簧，活塞的活塞内圈内壁设有导向筋；其结构设计要点是所述泵体内的阀杆外径套入内塞的内径，泵体的泵口内径与内塞的下塞口外径扣合固定密封，泵体外侧内塞的上塞口内径设有大于下塞口内径的下弹簧腔，内塞的上塞口内径孔口处设有外径小于上塞口内径的阀杆外径上弹簧腔，弹簧设置于阀杆上弹簧腔与内塞下弹簧腔套合的腔室内，即阀杆的杆口处上弹簧腔外径为上环圈，阀杆的上环圈套入内塞的上塞口内径。从而弹簧固定设置于阀杆外径与内塞外径构成的弹簧腔内，该泵芯在生产装配完成后作为共用件，即可通过自动化生产装配于对应的乳液泵等产品内，该泵芯在自动化生产装配时，该泵芯内的弹簧不易受设备或其他物品干扰。
所述阀杆的上环圈内径底部设有上台阶槽，泵体的泵口处内塞内径设有下台阶槽，弹簧的一端卡扣固定于阀杆的上台阶槽，弹簧的另一端卡扣固定于内塞的下台阶槽，弹簧处的阀杆外径设有均匀分布的竖直槽。上述结构便于弹簧的两端分别固定于阀杆和内塞，并且保证了弹簧在阀杆外径使用的顺畅，特别是弹簧腔室内压强的导通和稳定。
所述阀杆的扣圈筋下方设有活塞内圈，活塞的内圈顶部设有伸出活塞圈口的活塞内圈口，阀杆的活塞内圈与活塞的活塞内圈口密封套合，活塞的内圈底部圈口与阀针的钉头圈槽配合密封，阀针的底部设有锥形的底腔，阀针的底腔孔口外径斜面圈在阀杆按压时与弹套上方的泵体内壁相抵限位。从而活塞在复位状态下与阀杆通过活塞内圈口进一步密封，在复位状态和按压状态下与阀针保护密封，阀针的行程限位于泵体的弹套上方内壁，并通过阀针底部的底腔与弹套之间构成缓冲腔，稳定按压状态下的泵体内压强。
所述弹套的套筒与一侧套口的中心片之间设有Z字形弯曲的连接筋和镂空孔，弹套的中心片向泵体的中心锥形孔相抵，泵体的中心锥形孔为泵体的进水孔，泵体的中心锥形孔上方设有阶梯圈径，套筒的另一侧套口限位于泵体的阶梯圈径。现有一般泵芯弹套配活塞时密封性较差，该泵芯内弹套与泵体采用平面与平面的配合密封结构，该结构不易密封且实际密封面较少，平面不平或者倾斜都会使密封性能丧失。按压状态和复位状态下，通过弹套的连接筋位轻微变形，使弹套起到打开进液和关闭密封的效果。
所述泵体的泵口处外径与内塞的贴合处外径分别设有泵体凹槽圈和内塞凸起圈。上述结构便于该泵芯在同类产品中的装配固定。
所述泵体的泵体凹槽圈和内塞的内塞凸起圈过盈卡扣固定于大圈的上圈内径固定圈槽。上述为该泵芯通过泵体凹槽圈和内塞凸起圈固定于同类产品大圈的具体实施例。
所述大圈的下圈内圈底部设有大圈螺纹槽和大圈下内圈槽，大圈内的大圈螺纹槽外径设有大圈下外圈槽，大圈的大圈下外圈槽与下方的大圈筋位槽相通，大圈的大圈筋位槽内径大于大圈的大圈下外圈槽内径，大圈下圈的固定圈槽下方大圈下外圈槽内径与泵体的外径之间设有间隙，大圈筋位槽的内壁设有凸起的筋位，大圈顶部的固定圈槽外径设有顶部槽，鸭嘴的鸭嘴内圈与阀杆的杆口内径扣合，鸭嘴的鸭嘴外圈套入大圈的顶部槽内径，大圈的下圈外径直径、大圈的上圈外径直径、鸭嘴的外径直径依次递减。上述为具体实施例中乳液泵的具体结构，其中大圈的上述结构采用一体注塑成型的方式制得。
 有益效果
本发明结构设计合理，使用、装配方便，各部件装配紧密、稳定，密封性、稳定性好，弹簧稳定性和隔离效果好，材料制备方法可行；其适合作为同类产品的泵芯使用，及其同类产品的结构改进。

 本发明的实施方式
现结合附图，对本发明结构作进一步描述。如图1-图6所示，该泵芯的泵体3内设有弹套2、阀针4、活塞5，弹套设置于泵体内的吸管端槽孔内，活塞套入设置于阀针的钉部外径，活塞的外径与泵体的内壁相抵密封，阀针的钉部末端处钉圈槽外径与阀杆7内的扣圈筋扣合，泵体外侧的阀杆外径与泵体外侧的内塞6之间设有弹簧8，活塞的活塞内圈内壁设有导向筋。其具体结构如下：泵体内的阀杆外径套入内塞的内径，泵体的泵口内径与内塞的下塞口601外径扣合固定密封，泵体外侧内塞的上塞口603内径设有大于下塞口内径的下弹簧腔，内塞的上塞口内径孔口处设有外径小于上塞口内径的阀杆外径上弹簧腔，弹簧设置于阀杆上弹簧腔与内塞下弹簧腔套合的腔室内，即阀杆的杆口处上弹簧腔外径为上环圈702，阀杆的上环圈套入内塞的上塞口内径。同时，阀杆的上环圈内径底部设有上台阶槽，泵体的泵口处内塞内径设有下台阶槽602，弹簧的一端卡扣固定于阀杆的上台阶槽，弹簧的另一端卡扣固定于内塞的下台阶槽，弹簧处的阀杆外径设有均匀分布的竖直槽701。
上述泵体的泵口处外径与内塞的贴合处外径分别设有泵体凹槽圈和内塞凸起圈，阀杆的扣圈筋下方设有活塞内圈703，活塞的内圈顶部设有伸出活塞圈口的活塞内圈口501，阀杆的活塞内圈与活塞的活塞内圈口密封套合，活塞的内圈底部圈口与阀针的钉头圈槽配合密封，阀针的底部设有锥形的底腔，阀针的底腔孔口外径斜面圈在阀杆按压时与弹套上方的泵体内壁相抵限位。弹套的套筒202与一侧套口的中心片201之间设有Z字形弯曲的连接筋和镂空孔，弹套的中心片向泵体的中心锥形孔301相抵密封，泵体的中心锥形孔为泵体的进水孔，泵体的中心锥形孔上方设有阶梯圈径302，套筒的另一侧套口限位于泵体的阶梯圈径。
如图1、图2所示，该泵芯应用的实施例，泵体的泵体凹槽圈和内塞的内塞凸起圈过盈卡扣固定于大圈9的上圈内径固定圈槽，大圈的下圈内圈底部设有大圈螺纹槽和大圈下内圈槽，大圈内的大圈螺纹槽外径设有大圈下外圈槽，大圈的大圈下外圈槽与下方的大圈筋位槽相通，大圈的大圈筋位槽内径大于大圈的大圈下外圈槽内径，大圈下圈的固定圈槽下方大圈下外圈槽内径与泵体的外径之间设有间隙，大圈筋位槽的内壁设有凸起的筋位，大圈顶部的固定圈槽外径设有顶部槽，鸭嘴的鸭嘴内圈与阀杆的杆口内径扣合，鸭嘴的鸭嘴外圈套入大圈的顶部槽内径，大圈的下圈外径直径、大圈的上圈外径直径、鸭嘴的外径直径依次递减。
该泵芯的弹簧结构改进如下：弹簧内孔套入阀杆圆柱的竖直槽外侧，弹簧一端置于阀杆的上台阶槽内固定，另一端置于内塞的下台阶槽内固定。从而弹簧在使用过程中不与液体接触，避免弹簧与液体起化学反应，不影响弹簧的外观、功能及使用液体被污染变质等异常。活塞配阀杆密封结构改进如下：阀杆底端内壁的活塞内圈与活塞密封筋的活塞内圈口处配合密封，形成一个顺液体流向的密封结构，在试喷时，如4所示，A处密封在液体试喷时几乎不受液压影响，能大大改善因快速试喷或高粘度高液压的情况下，试喷漏液问题。现有同类外置弹簧泵芯的原设计，对应密封处为逆液体流向密封，极易受液压的影响而渗漏，在快速按压或者高粘度高液压情况下，将无法有效密封。
该泵芯的弹簧侧边歪斜按压试喷改进如下：上述阀杆圆柱的竖直槽穿过内塞的上塞口内孔中，确保阀杆在上下运动过程中与内塞呈垂直中心运动，并且阀杆上部上环圈置于内塞的上塞口内孔中，再次确保阀杆与内塞的中心，形成双层控制中心结构；有效改善组装后阀杆歪斜而导致头帽歪斜问题，以及大大改善侧边歪斜按压试喷时产品漏液或者无吸力等不良异常。如图2所示，该泵芯在实际应用中在侧边按压头帽时，头帽因受力不均出现歪斜连带阀杆歪斜，但随着行程的下压阀杆上部上环圈与内塞的上塞口内壁直伸配合也逐步增加，所以能有效控制阀杆歪斜，确保与阀杆连带装配的零件不受歪斜影响，大大增加产品稳定性及使用广泛性。，现有同类外置弹簧泵芯的原设计中阀杆仅与内塞内孔配合，所以侧边按压头帽试喷时，阀杆极易歪斜从而连带阀针、活塞等歪斜，出现许多功能异常，产品稳定性较差，适用性较小。
该泵芯的弹套与泵体配合密封改进如下：弹套置于泵体中，弹套中心片的圆弧凸面与泵体中心锥形孔的圆弧凹面配合密封，弹套的套筒套口与泵体的中心锥形孔上方阶梯圈径筋位配合固定；通过弹套的连接筋位轻微变形，使弹套起到打开进液，关闭密封的效果。现有同类外置弹簧泵芯的原设计中弹套配活塞结构时，弹套与泵体采用平面与平面的配合密封结构，存在不易密封且实际密封面较少的问题，平面不平或者倾斜都会使密封性能丧失。而该泵芯的弹套结构改进后的圆弧凹凸密封结构，其配合密封面较平面结构大大增加，且圆弧凹凸配合，倘若稍有倾斜也会随着圆弧斜面自动导向回正，大大增加稳定性和密封性。
上述该泵芯的阀针由环保高新材料制成，所述环保高新材料由以下重量份的原料组成：PP树脂60-70份，增韧剂5-10份，相容剂2-8份，增强粉体5-10份，石墨烯3-5份，抗氧化剂0.2-0.4份，润滑剂0.5-2份，硅烷偶联剂0.1-0.3份；所述PP树脂为均聚PP树脂、共聚PP树脂中的一种或者两者的混合物；所述增韧剂为聚烯烃弹性体、乙烯/甲基丙烯酸共聚物、乙烯-醋酸乙烯共聚物中的任意一种或者任意两种的混合物或者三者的混合物；所述增强粉体为云母粉与玻璃微珠、有机纤维微珠或者石棉微珠按1-5:2-4混合而成的混合物，增强粉体的粒径为400目-800目；所述相容剂为聚丙烯接枝马来酸酐、聚乙烯接枝马来酸酐的一种或者两者的混合物；所述的增韧剂为POM、PVC、PET 或者PETG；所述抗氧化剂为由抗氧化剂1076和抗氧化剂168按1:1的重量比混合而成的混合物；所述润滑剂为聚乙烯蜡、乙撑双硬脂酰胺、季戊四醇四硬脂酸酯中的任意一种；所述硅烷偶联剂为硅烷偶联剂KH550或硅烷偶联剂KH560中的一种。
