Description

一种环保型喷泵 技术领域
本发明涉及日常喷射瓶罐技术领域，具体为一种操作容易的环保型喷泵。
背景技术
日常生活中，我们经常用到能喷射液体瓶罐，根据喷嘴形状和内部结构的不同，有的能喷射雾状液体，有的能喷射乳状液体。最常见的比如洗手液、清洁液、消毒或化妆水、及其美容美发用品等均采用喷射瓶，用手按压喷嘴，液体自喷射瓶喷口喷出。
经检索发现，现在技术文献和专利文献，虽然有很多关于喷射瓶罐方面的改进，但是基本结构和原理相差无几：基本结构包括壳体及设置于壳体上的按头，在壳体内依次装上上阀门、活塞、弹簧、水柱及下阀门，活塞与壳体内腔形成的气密性活动联结，上、下阀门分别位于壳体的上、下方，活塞在按头的按压下和弹簧的作用下在壳体内反复上下运动，将瓶内液体吸入壳体，并从按头上的吸嘴喷出。有的还设有钢珠和导管，利用弹簧作为复位动力，下阀门作为开关，钢珠作为下阀门的阀瓣，当将手按下时，壳体内的液体从喷嘴喷出，当将手放下时，液体通过导管，经过下阀门的钢珠，再次补充到壳体。
对于液状化妆品或药品，一般都含有溶剂及其他化学物质，对钢珠及金属弹簧具有一定的腐蚀作用，即使是用上不锈钢做为材料，也不能避免，因为所谓的不锈钢，从严格意义上说，也仅仅是减缓腐蚀而已，并不能真正完全避免化学品的侵蚀，由此也就会对化妆品或药品造成污染，产生不良效果；其次，由于增设钢珠和金属弹簧使得产品成本增加；在使用完里面的液体，又由于这种结构金属和非金属混杂在一起，使得该空瓶难以简单回收重新利用。特别在2019年全国已经启动了垃圾分类工作，并规定了相关的规章制度和惩罚措施。特别是在上海垃圾分类率先实施，并开具了全国第一张垃圾分类不符合规定的罚单。

本发明的工作原理：本发明的关键在于选用的气囊和逆止阀，结构、材质。当用手按压喷嘴时，压力通过压杆传递到气囊上，气囊在压力作用下，向下运动，且变形，该形变力将位于气囊下面和托盘之 间的容腔内的液体通过上逆止阀下部的漏孔排出，并通过托盘内部通道由喷嘴喷出；当手放下一瞬间，气囊自动回复原型，此时会有一个吸力，该吸力将下逆止阀上的阀片吸开，将喷瓶内的液体吸到容腔内对液体进行补充。
有益效果：本发明的环保型喷泵,整体采用软硬塑料件，产品用完后，可以直接回收利用；避免采用金属弹簧，尤其对一些易腐蚀性液体，非常适用本装置；适用于导管和活塞两种形式的产品，应用范围广，几乎对日常生活常见的液体喷瓶做到了全覆盖；根据气囊以及逆止阀上漏孔的大小，可以控制喷液量和喷液射程；根据液体的密度，可以调整气囊的直径以及托盘的下部溶液管的直径大小，比如如果要装的是牙膏，那么就要用相对较粗大的气囊和托盘。本发明特别的结构构思以及巧妙的材料选取，在本技术领域是一种创造式的发明，使得本发明节能环保，用处宽广，市场前景更是不可估量，可称得上21世纪日常喷射领域的一枝独秀。

具体实施方式
下面结合附图对本发明的实施例作详细说明：本实施例在以本发明技术方案为前提下进行实施，给出了详细的实施方式和具体的操作过程，但本发明的保护范围不限于下述的实施例。
如图1-7所示，图中包括逆止阀4、气囊2、压杆1、托盘3，压杆1上端连接一喷嘴，压杆1中心处开有通道12，该通道12和喷嘴内的通道联通，所述压杆1的下端插进气囊2上的深井状结构内，所述压杆1的下端和上逆止阀41之间留有空隙。
逆止阀4由分别由软体材料制成阀片411、阀柄412一体注塑而成，所述逆止阀包括一上逆止阀41、一下逆止阀42。
气囊2为一软性半球体，该软性半球体由一位于外侧的圆帽体21和一位于中间的圆筒体22一体注塑成形，圆筒体22的上部和圆帽体21的背面一体成型，构成一深井状结构，该深井状结构沿着圆帽体21的中心延伸，圆筒体21的底部中心处设有若干漏孔，圆筒体21的底部中心处安装有上逆止阀41，该上逆止阀41的阀片411位于圆筒体21底部的漏孔之上。
气囊2外侧的圆帽体21采用硅胶制成，气囊2内侧的圆筒体22采用PP制成，气囊2内侧的圆筒体22硬度比气囊2外侧的圆帽体 21硬度大，因为圆筒体22要作为液体排出的必经通道，且圆筒体22的底部要安装上逆止阀41，故对硬度有一定要求；圆帽体21作为气囊2的变形部件，需要在压力作用下容易变形，且容易复位，故圆帽体21的材质要稍软一些。
气囊2内侧的圆筒体22的底部中心开有一通孔一211，上逆止阀41的阀柄412通过该通孔一211，阀柄412上设有倒扣4121，上逆止阀41通过倒扣4121固定在气囊2内侧的圆筒体22的底部。通孔一211的周围对称地设有两个半月状的漏孔一222，两个半月状的漏孔一222分别位于上逆止阀41的阀片411下面，对两个半月状的漏孔一222进行密封，上逆止阀41的阀片411紧贴在两个半月状的漏孔一222上。
气囊2的圆帽体21的直径比上部托管31的直径略大一些，以增大气囊2在上部托管31内的膨胀度，进而增大气囊2在上部托管31内的密封效果。
气囊2的圆筒体22的高度比气囊2的圆帽体21的高度高、矮或相同均可，因为气囊2内侧的圆筒体22位于下部溶液管32上，在气囊2受到按压时，圆筒体22能在下部溶液管32内上下自由活动，故此时圆筒体22的高度并不影响气囊2的受压变形。
气囊2外侧的圆帽体21的边缘架在上部托管31底部台阶上，托盘3为一一体成形的台阶管，该台阶管分为上部托管31和下部溶液管32，上部托管31和下部溶液管32的直径不同，上部托管31的上端开口，通过上部托管31底部台阶过度到下部溶液管32，下部溶液 管32的底部设有封盖321，
下部溶液管32底部的封盖321的中心处设有若干漏孔，下部溶液管32的底部中心处安装有下逆止阀42，该下逆止阀42的阀片位于下部溶液管32的底部的漏孔之上，气囊2的圆帽体21和圆筒体22下侧和托盘3之间形成一用来容纳待喷射液体的容腔。

托盘3的下部溶液管32底部的封盖321中心处开有一圆形凹槽3210，该圆形凹槽3210的中心开有一通孔二3211，下逆止阀42的阀柄通过该通孔二3211，阀柄上设有倒扣，下逆止阀42通过倒扣固定在下部溶液管32底部的封盖321上。
托盘3的下部溶液管32底部的通孔二3211周围对称地设有两个半月状的漏孔二3212，两个半月状的漏孔二3212分别位于下逆止阀42的阀片下面，下逆止阀42的阀片嵌入在圆形凹槽3210内，并紧贴在两个半月状的漏孔二3212上，对两个半月状的漏孔二3212进行 密封。
实施例二(导管款)：
如图12所示，托盘3的下部溶液管32的下面连接一导管，导管的上端插在下部溶液管32一外凸圆口3213上，外凸圆口3213和下部溶液管32一体注塑成形，导管的下端深入到喷瓶6下部，外凸圆口3213包围在下部溶液管32底部的漏孔外围，下部溶液管3213底部的下逆止阀42的阀柄位于外凸圆口3213的中心位置。其余结构同实施例一，不再累述。
实施例三(托盘采用直管)：
如图13所示，托盘为一直管7，该直管7的底部设有一盖体71，盖体71中心设有一凹陷槽711，凹陷槽711的中心开有一穿孔712，穿孔712周围设有若干漏孔，下逆止阀42的阀柄穿过穿孔712固定在盖体71的凹陷槽711内，该下逆止阀42的阀片位在漏孔之上，气囊2的圆帽体21的边缘架在盖体71上，气囊2的圆筒体22的底端位于气囊2的圆帽体21的内部，以确保气囊2的圆筒体21和直管7底部的下逆止阀42之间留有空隙，气囊2的圆筒体22的高度比气囊2的圆帽体21的高度小，以保证在气囊2受到上部压力时，能有足够变形空间，将所述直管7内的液体排出。直管7底部的盖体71上设有一以盖体71中心为圆心的圆环状的限位槽713，气囊2的圆帽体21的边缘位于限位槽713内，在确保气囊2在受压变形时不会滑动。其余结构同实施例一，不再累述。
