具体实施方式：
下面以具体实施例对本发明作进一步描述，参见图1-2：
一种出水阀，包括具有出水孔2的阀体1，所述出水孔2内设有限位环面，限位环面上开设有吸剂槽3，所述阀体1上设有内端与吸剂槽3连通的吸剂通道 4，吸剂通道4内设有能阻止液体向外流出的单向组件，位于限位环面内、外两侧的出水孔2上分别轴向滑动连接有文氏管体5、以及内端能与文氏管体5相抵靠的活塞环套6，文氏管体5的内孔孔径内端大于外端，出水孔2的出水端内液体低压时，文氏管体5在弹性件的弹力下向外滑动直至其外壁面抵靠贴合在限位环面上、且开设在文氏管体5内孔外端上的吸剂孔7与吸剂槽3连通；出水孔2的出水端内液体高压时，活塞环套6在水压压力下推动文氏管体5克服弹性件的弹力向内滑动。
即本发明的工作原理为：借助文氏管体5的内孔结构，在阀体1正常出水状态下，文氏管体5抵靠并贴合在限位环面上，水液只能从出水孔2的进水端经文氏管体5的内孔流入出水孔2的出水端，由于因文氏管体5的内孔孔径从内至外变大，水液的流速会降低并形成负压，进而使得外界的剂液在该负压下从吸剂通道4被吸入、并经吸剂槽3与吸剂孔7进入文氏管体5的内孔中，最终剂液与液体混合形成泡沫水而被排出；当阀体1出水量较小或停止出水时，水液持续挤压在出水孔2的出水端处以形成高于出水孔2进水端的高压，从而活塞环套6在高压作用推动文氏管体5向内滑动，使得文氏管体5与限位环面分离，进而水液能从文氏管体5与限位环面之间流向出水孔2的出水端，与此同时，吸液孔在单向组件的作用下无剂液流入。
本发明结构巧妙、设计合理，在正常出水时、借助文氏管体5中液体流动所产生的负压而将剂液吸入阀体1内，进而达到泡沫液自动混合的目的；而在出水较少或停止出水时，自动停止对剂液的吸入混合，其无需人为进行混合，操作便利。
更进一步，为了使得文氏管体5能够稳定在贴合在限位环面上，所述限位 环面为内大外小的锥面，文氏管体5的外壁面与限位环面结构相对应，并且，为了确保限位环面与文氏管体5之间的密封性，限位环面与文氏管体5的外壁面之间设有分别位于吸剂槽3内外两侧的密封圈一8。
同时，在停止出水时，为了能够避免出水孔2内水液持续增压，同时优化弹性件的具体安装位置：位于所述文氏管体5内侧的出水孔2内设有能沿其轴向滑动的出水锥阀9，出水锥阀9的内端能够抵靠并堵塞出水孔2的进水端口、外端端面开设有容置槽10，所述弹性件为设置在容置槽10内的压缩弹簧11，即在出水孔2内的液体处于水压过大时，出水锥阀9能够向内滑动并抵靠堵塞在出水孔2的进水端口处。
更进一步，为了使得出水锥阀9能够稳定堵抵靠并塞在出水孔2的进水端口处，所述出水锥阀9的内端外沿面以及出水孔2的对应壁面均为内小外大的锥面，且出水锥阀9的内端外沿面上套装有密封圈二12。
并且，为了确保出水锥阀9的设置不影响水液从出水孔2的进水端流向文氏管体5，所述出水锥阀9的外轮廓呈多边形结构、且出水锥阀9的外壁面与出水孔2的内壁面之间形成过水通道，同时，所述容置槽10的槽底部开设有过水通孔13，即水液能够分别从过水通道以及过水通孔13中流向文氏管体5。
为了使得活塞环套6能够在出水孔2内轴向稳定滑动，所述出水孔2的出水端部为台阶孔结构、且从内至外依次包括有小径部一与大径部一，小径部一与大径部一间形成内定位台阶，所述活塞环套6的外侧壁从内至外包括有滑动连接在小径部一上的小环部14、以及滑动连接在大径部一上的大环部15，小环部14与大环部15之间形成外定位台阶，内定位台阶与外定位台阶之间形成空气腔16，阀体1上开设有与空气腔16相连通的通气孔17，即活塞环套6被文 氏管体5推动而向外轴向滑动时，内定位台阶远离外定位台阶，外界空气经通气孔17进入逐渐变大的空气腔16内；而活塞环套6推动文氏管体5向内轴向滑动时，内定位台阶靠近外定位台阶，逐渐变小的空气腔16内的空气经通气孔17向外排出。
更进一步，为了确保活塞环套6与出水孔2之间的密封圈，所述小径部一与小环部14之间、以及大径部一与大环部15之间均设置有密封圈三18。
同时，为了能够对活塞环套6的轴向滑动进行限位，位于所述活塞环套6外侧的出水孔2上开设有环形凹槽，环形凹槽内套装有对活塞环套6轴向限位的卡簧19。
此外，单向组件可以采用市面上常见的单向薄膜组件，而在本实施例中，所述吸剂通道4为台阶孔、且从内之外依次包括有大径部二与小径部二，所述单向组件包括有设置在大径部二内的钢珠20，钢球的内侧与阀体1之间设置有吸剂弹簧21，且在吸剂弹簧21的弹力下钢球抵靠并堵塞在小径部二的内端口处。而在本实施例中，为了进一步提高钢球对吸剂通道4内的堵塞能力，在大径部二的外端口处套装有密封圈四22，钢球通过抵靠并堵塞密封圈四22的内环、以实现对小径部二的内端口的堵塞。
并且，在本实施例中，阀体1的具体结构为：所述阀体1为三通接头23，三通接头23的出水端口螺接有出水接头24，所述限位环面、文氏管体5、活塞环套6均设在出水接头24的内孔中，所述吸剂通道4开设有三通接头23上、且出水接头24上开设有连通吸剂通道4与吸剂槽3的吸剂口25，其中，出水接头24的外端可通过快速接头26或其他常见连接件与水管连通。
上述实施例仅为本发明的较佳实施例之一，并非以此限制本发明的 实施范围，故：凡依本发明的形状、结构、原理所做的等效变化，均应涵盖于本发明的保护范围之内。
