本公司第二代产品已获得发明专利权，授权公开号为CN104029925B。具体内容如下：一种新型可拆卸可充式喷液瓶，该喷液瓶整体由两部分组成，包括瓶身和瓶底，瓶身和瓶底通过阀座可拆卸式连接，阀座为一体式阀座，其外壁上设有定位筋、密封槽、凹凸齿结构与瓶身连接，同时阀座外壁上设有螺纹与瓶底连接；阀座上还设有阀座进液孔和阀座排气孔，阀座两侧分别设有高、低柱，高、低柱均为中空结构，内设有腔室，与阀座进液孔连通的腔室为进液腔，与阀座排气孔连通的腔室为排气腔，排气腔同时与排气管连通；阀座的内腔插有阀芯，阀芯设计为整体不对称结构，阀座的内腔和阀芯外轮廓形状相适，为整体不对称结构，阀芯只能以唯一方式***阀座的内腔；阀芯的顶端与内腔之间装有弹簧；阀芯内部设有通孔，与阀芯中间段壁面上进液口连通，阀芯与阀座进液孔之间设有密封圈一，阀芯与阀座排气孔之间设有密封圈二，工作时，弹簧受外力压缩后，密封圈一和密封圈二之间形成密闭的进液通道，该通道与阀座进液孔连通，密封圈二下方、阀芯与阀座内腔之间的间隙形成排气通道，弹簧受外力压缩后排气通道与外界大气环境连通。这种喷液瓶不仅便于携带，而且便于拆卸清洗，密封性好，可防止跟转，生产工艺简单，可循环充液重复利用，灌装不同气体不会串味。
本公司第二代产品已生产了两年多，在生产过程中积累了一些问题。这些问题急待通过改善的新的结构来解决，具体问题如下：
(1)充液口、排气口为圆形，须人工开孔，开孔位置精度和直径大小难以获得保证，生产效率低，成材率低；
(2)由于阀芯采用非圆形对称结构，必须带方向安装，安装效率低，充液整体通道、排气整体通道过于复杂；

具体实施方式
一种紧凑型底部充装喷液瓶，如图所示，包括喷头组件1、瓶身2和安装于瓶身2内部的充液排气功能组件。喷头组件1安装于瓶身2上部。另外，瓶身2外部可增设金属件瓶套22，瓶身2上部可增设塑料或/和金属的瓶盖23与瓶身2之间形成卡套式或摩擦式连接。
如图1所示，充液排气功能组件包括阀芯3、阀套4、阀座5、尾盖6，四者共同配合实现充液排气功能。阀芯3插于阀套4内，阀芯3的顶端与阀套4 的内腔之间装有弹簧47，充液时，阀芯3在阀套4内做上升运动，并通过弹簧47复位，阀套4外侧套有阀座5，阀套4与阀座5连接处的下端留有空隙，尾盖6插于空隙内。
如图2所示，为本发明阀芯3的结构。阀芯3为一体式结构。阀芯3包括上凸环31和下凸环32。上凸环31在充液起始位时密封阀套充液口45。上凸环31内设有阀芯限位柱，与阀套4限位柱相配合，对阀芯3上行程进行限位。也可不设阀芯限位柱，其并不影响阀芯3充液功能的实现。同时，阀芯3限位柱上套有弹簧47，该弹簧47起复位作用，当阀芯3升高到上行程结束位，失去外界压力时，将阀芯3恢复到充液起始位。当不设阀芯限位柱时，弹簧47可套在阀套限位柱42。上凸环31下方还设有密封槽311和O型密封圈312，用于增强针对阀套充液口45的密封。下凸环32在充液起始位时密封阀套排气口46。下凸环32内设有内套33，内套33内为阀芯进液通孔30。上凸环31与下凸环32之间设有用于液体充入的沿圆周一圈的凹陷34，凹陷34中间位置开有阀芯充液口35。阀芯充液口35任何形状均可，优选采用长方形或腰圆形，一方面可以缩小关键高度尺寸，另一方面便于模具制作。本发明阀芯进液通孔30内还设有硅胶软垫7结构。硅胶软垫7可以更好的密封阀芯3下端开口与待充液大瓶之间的间隙，并且缓冲对待充液大瓶的压力。硅胶软垫7内设有供液体流过的通孔71。此处不应当限制必须有硅胶软垫7，改变内套33阀芯进液通孔30的形状使其便于对准待充液大瓶的方案也可以。只要带有阀芯进液通孔30、可以实现充液功能的阀芯3都应涵盖在本发明的保护范围中。
如图3所示，为本发明阀套4的结构。阀套4为一体式结构。阀套4包括筒状的阀套壳41。阀套壳41内顶面中心设有阀套限位柱42，阀套限位柱42对阀芯3进行上行程的限位。阀套限位柱42可于与阀芯限位柱(当有时)配合。阀套壳41中部设有阀套充液口45，阀套充液口45所在圆周位置设有一圈环槽48，该环槽48凹陷可保证阀套充液口45与瓶身2内部连通。也可不设环槽48，此处不影响充液功能的实现。阀套充液口45下方设有阀套排气口46。阀套充液口45、阀套排气口46任何形状均可，优选采用长方形或腰圆形，一方面可以缩小关键高度尺寸，另一方面便于模具制作。在阀套充液口45下方、阀套排气口46两侧分别设有第一密封圈槽43、第二密封圈槽44。阀套4上设有多处密封筋 9，这些密封筋9用于与其他部件的连接。
如图4所示，为本发明阀座5的结构。阀座5为一体式结构。为了更好的连接阀套4，阀座5上端设有保持架51。本实施例中保持架51由三个呈圆周均匀分布、并向圆心汇拢的支撑架组成。保持架51形状不应限于此，也可以是两个支撑架组成，带有保持架51、并实现定位和/或装配功能的阀座5都应属于本发明的保护范围。阀座5还包括有一阀座台52，阀座台52用于与瓶身之间的密封连接。阀座台52与保持架51之间设有阀座排气孔55，阀座排气孔55上方可以密封***排气管21。优选地，在连接时，排气管21与阀座排气孔55的开口楔形密封连接。这样排气管21在阀座排气孔55的楔形孔中越插越紧，可避免液体从连接处漏出，密封效果好。排气管21的高度可做高些，以便提高液体可容空间，在做高的同时留有空隙，使气体可排出。充液时，注意瓶内液体高度不要超过排气管21的高度，防止充液时液体从排气管21溢出。阀座台52侧面设有与瓶身2侧壁面卡接的台阶53，该台阶53可适应不同的金属件瓶套22，例如平底金属件瓶套22和圆弧底金属瓶套22。阀座台52下部设有与尾盖6连接的套环54。阀座5上设有密封筋9和卡扣筋8，这些密封筋9和卡扣筋8用于与其他部件的连接。
如图5、6所示，为本发明尾盖6的结构。尾盖6为一体式结构。尾盖6包括设置有尾盖凸筋66的外圈61、和用于限制阀芯3下行程的内圈62。尾盖6外圈61顶面设有一圈间断的、窄于尾盖6外圈61顶面宽度的尾盖凸筋66。尾盖凸筋66顶着阀座5，尾盖6上端肩部两侧还设有尾盖倒角65，尾盖倒角65可增大排气间隙一的排气空间。外圈61和内圈62底部连接，并设有排气缺口63，排气缺口63可以是两个，也可以是沿圆周均匀分布的若干个，此处不应当受到限制。外圈61和内圈62之间留有阀套4的安装空隙。内圈62外壁面圆周设有竖向的、用于产生排气间隙二64的纵筋67。同样，尾盖6上设有密封筋9和卡扣筋8，这些密封筋9和卡扣筋8用于与其他部件的连接。
上述阀芯3、阀套4、阀座5和尾盖6，四者共同配合实现充液排气功能。当包括有硅胶软垫7时，五者共同配合实现充液排气功能。
充液功能的实现：阀芯3设有阀芯进液通孔30，阀芯3侧壁面设有阀芯充液口35，阀芯充液口35与阀芯进液通孔30相通；阀套4上设有阀套充液口 45，阀套充液口45与瓶身2内部相通。静止时，阀套充液口45由阀芯3密封。充液时，阀芯3在阀套4内上升移动，阀套充液口45被打开，通过阀芯3上的凹陷34与阀芯充液口35连通。这样液体从阀芯进液通孔30进入阀芯充液口35、经过凹陷34进入阀套充液口45后，直接进入瓶身2内部。
排气功能的实现：阀座5上设有阀座排气孔55，阀座排气孔55上密封连接有排气管21，排气管21连通瓶身2的上部气体。尾盖6顶面设有一圈间断的、窄于尾盖6顶面宽度的尾盖凸筋66，尾盖6顶端与阀座5下表面未接触处形成排气间隙一68。尾盖6内圈62外壁上设有纵筋67，纵筋67使内圈62和阀套4之间形成排气间隙二64；排气管21、阀座排气孔55、排气间隙一68、阀套排气口46、排气间隙二64首尾相通，共同形成排气通道。静止时，阀套排气口46由阀芯3下半部分密封，排气通道被隔断，充液时，阀芯3在阀套4内上升移动，阀套排气口46被打开，排气通道连通，与尾盖6底部的排气缺口63连通，排气缺口63自然与大气连通。本发明开设了新的排气区域，使得功能性结构更为紧凑，进而增加液体的有效容纳空间。
阀座5上端设有保持架51，对阀套4进行位置固定。可防止充液时，阀套4被顶出。同时，让阀套4、阀座5、尾盖6更好地连接，三者形成一个新的“阀体”，让阀座排气孔55、排气间隙一68、阀套排气口46、排气间隙二64相互连通，形成新的排气通路。
如图7所示，安装时，为了解决原来各部件连接处O型密封圈尺寸偏差大，密封效果不理想的问题，本发明阀套4与尾盖6之间通过设置密封筋9和O圈双重密封连接，阀座5与尾盖6之间通过设置密封筋9、卡扣筋8共同作用双重密封连接，阀套4与阀座5之间通过设置密封筋9和O圈双重密封连接，阀座5与瓶身2之间通过设置密封筋9、卡扣筋8共同作用双重密封连接。本发明通过密封筋9进行密封，通过卡扣筋8来密封并防止各部件之间的脱落，结构设计更为合理，对工人来说，制作也更为方便，可稳定生产质量。
如图8所示，充液时，将外界的待充液大香水瓶10的喷嘴对准瓶底充液口，然后下压本申请喷液瓶，使阀芯3上升并压缩弹簧47，上凸环31上升，处于上凸环31原位置处的阀套充液口45被打开，压缩弹簧47至最大压缩位，阀套充液口45经过凹陷34与上升到位的阀芯充液口35连通。此时，阀芯进液通 孔30、阀芯充液口35、凹陷34、阀套充液口45、瓶身2连通，形成整体进液通道，大瓶里的液体在大瓶内泵头的压力作用下进入瓶身2。
同时，当大瓶内的液体进入瓶身2后，瓶身2内的气体被压缩，引起瓶内气体压强增大，因此需要将瓶身2内的气体排出，以保证持续充液。上述充液时，下凸环32同时也上移，阀套排气口46被打开。此时，排气管21、阀座排气孔55、排气间隙一68、阀套排气口46、排气间隙二64、排气缺口63连通，形成整体排气通道。瓶身2内的气体被压缩，压强增大，通过整体排气通道排出。
充液完成后，松开大瓶喷嘴，阀芯3在弹簧47的作用下迅速回位，上凸环31、下凸环32继续分别与阀套充液口45、阀套排气口46形成密封关系，防止瓶身2的液体外泄。
