[0015] 所述的高度及深度与密封环(14)的直径相一致的,呈凹形的圆环结构的锁紧口(12), 位于的弹簧腔 (10) 的上端口上, 随着锁紧盘 (11 ) 在锁紧簧 (8) 的弹力及外力的作用下, 在自锁紧取液头(02)上所作的垂直魂动, 实现锁紧口 (12) 与密封环(14) 的闭合, 以锁紧 水包 (114) 的插入口, 保障水包 (114) 使用中不会发生渗漏的现象。
[0016] 所述的密封环 (14) 的外径, 略大于吸液头 (16) 的锥底, 以吸液头 (16) 的锥度趋 向, 设定为密封环 (14) 的外径值; 密封环 (14) 的内径, 小于封环槽 (13) 的内径, 密封环 ( 14) 紧实地嵌装于封环槽 (13)中。
[0017] 所述的密封环 (14), 埋设于吸液头 (16) 的锥头与中空圆柱结合部的封环槽(13)中, 密封环(14)的外径略大于吸液头(16)的锥底的直径,呈自然过渡的状态,以方便吸液头(16) 能顺势插入水包(114), 实施取水作业; 密封环 (14) 的内径, 小于环形封环槽(13)的直径, 以使密封环 (14) 能紧实地嵌合于取液头(16)上。
[0018] 所述的密封环 (14), 作用有二, 其一是, 通过与锁紧口 (12) 的闭合, 自动锁紧水 包(114)的插入口, 使水包(114)中的饮水不会向外渗漏。其二是, 限定锁紧盘(11)的活动范 围, 使锁紧盘 (11 ) 不会脱离自锁紧取液头 (02)。
[0019] 所述的气阀球 (4), 由气阀簧 (3) 紧压安装于阀球座 (5) 上。
[0020] 所述的气阀帽 (1 ) 上, 设有气阀孔 (2)。
[0021] 所述的凹底水箱 (110) 底部的中心位上, 设有 3 公分左右深度的环形槽, 当饮水将 尽的阶段, 既可汇聚饮水于其中, 又可适应吸液头(16)的几何形状, 使吸液头(16)能伸入 其中, 尽量吸完饮水。
[0022] 所述的水箱盖 (101 ) 与凹底水箱 (110) 间, 采用铰链结合, 水箱盖 (101 ) 的前端, 设有箱盖锁扣 (105); 所述的自锁紧取液头 (02) 的设定高度, 大于盖合后的水箱盖 (101 ) 与水包(114)顶面间的距离, 两者距离差为 3公分, 当放下盖子扣上箱盖锁扣(105)时, 位 于水箱盖(101 )内侧的中心的定位短柱 (102)与定位柱孔 (6、 103)套合后, 利用自锁紧取液头 (02) 高于盖合后的盖面与水包 (114) 的距离差原理, 通过自锁紧取液头 (02) 中的锁紧盘 ( 11 ), 实现对水包 (114)产生压力, 虹吸通道内的空气, 在压力作用下被排尽, 虹吸原理得以 实现。
[0023] 进一步, 所述的锁紧盘 (11 ) 对水包 (114) 所产生压力, 水包(114)受压力的影响, 饮水被压入虹吸通道, 虹吸通道内的空气, 因受水流的挤迫, 向排气通道移动, 一旦虹吸通道 内的空气被排尽, 虹吸原理就得以实现。
[0024] 换言之, 当放下盖子, 合上箱盖锁扣 (105) 时, 由于距离差的原因, 锁紧盘 (11 ) 下的水包(114)会被压下 3公分左右的压缩洼陷, 这一压力的产生, 足以驱使虹吸通道中的空 气, 顶开气阀球 (4) 实现自动排气的目的。 当虹吸通路中的空气被排尽时, 虹吸原理形成, 自锁紧取液头 (02), 就可实 M对饮机的虹吸供水。
[0025] 自动排气的动作机理为: 水箱盖(101) 通过附设于盖子内侧上的定位短柱(102), 对 自锁紧取液头(02)上定位柱孔 (6、 103)实施精准套合,合上水箱盖( 101 ),锁定水箱锁扣(105), 由于自锁紧取液头(02)的高度大于水箱盖(101 )与水包(114)之间的距离,这样,水箱盖(101 ) 对自锁紧取液头(02)产生了压力, 压力传递路径为: 定位短柱 (102)—定位柱孔 (6、 103) → 锁紧盘 (11 ) —水包(114), 水包 (114) 在外力的影响下, 把饮水压入倒虹管(107) , 由于水 流进入倒虹管(107), 倒虹管(107)内的空气因被挤压, 进入上三通(108) 向排气口方向移动, 当压力大于气阀簧时, 气阀球 (4) 受到压力的作用被顶开, 实现自动排气。
[0026] 所述的排气机构当然也适用于手动排气的方式来实现排气, 采用手动排气时, 只须一 直按住自锁紧取液头 (02), 直到气阀帽 (1 ) 中的气阀孔 (2) 出水即可。

[0035] 下面结合附图详细描述本发明:
[0036] 如图 3 所示, 自锁紧取液头 (02) 是从水包 (114) 的上位插入的, 是以虹吸的架构 实现取水的, 吸液头 (16) 中的吸液口 (15), 即是虹吸架构的吸水起始点。 众所周知, 实现 虹吸原理的条件有二, 一是出水口必须低于水平面, 二是虹吸通道中不得留有积聚的空气。
[0037] 应用的实践证明, 虹吸供水的袋装水机的每一次换水操作, 都会有空气进入虹吸通道 中, 这就产生了每次换水就得先要做排除积聚于虹吸通道中空气的麻烦事, 这就是说, 要采用 虹吸取水的模式,首当其冲要解决的技术问题就是要排除机器中的空气,本专利采用的是自动 排气的技术方案。
[0038] 本专利的自动排气方案是这样实现的:
[0039] 首先, 本专利设计了一个闭合式的排气通路。 所述的闭合式的排气通路, 起于吸液头 ( 16) 中的吸液孔(15), 经由止回瓣 (9)、 伪三通(7)、 倒虹管(107)、 上三通(108)、 阀球座 (5)、气阀球(4)、气阀孔(2)、排气管(104)。平时, 闭合式的排气通路是处于常闭状态的, 当产生外部压力时, 位于阀球座(5)上的气阀球(4)被虹吸通道中空气顶开, 空气经气阀帽 ( 1 ) 上的气阀孔 (2) 从排气管 ( 104) 排出。
[0040] 其次, 本专利还设计了一个自动排气的动力源: 由于水箱盖 (101 ) 盖合后, 从水箱 盖(101 )到水包 (114)顶面间的距离, 与自锁紧取液头(02) 的高度相比, 设有 3公分的距 离差, 运用距离差的原理, 当放下盖子扣上箱盖锁扣 (Η)5) 时, 自锁紧取液头 (02) 中的锁 紧盘(11 ) 向水包(114)施压, 水包(114)受到压力的影响, 饮水被压入虹吸通道, 虹吸通道内 的空气因受水流的挤迫, 向排气通道移动, 一旦虹吸通道内的空气被排尽, 虹吸原理就得以实 现。 [0041] 如图 3所示, 凹底水箱 (110 ) 底部的中心位上设有深度为 3公分左右的环形槽, 当 饮水将尽的阶段既可汇聚饮水于其中, 又可适应吸液头 (16) 的几何形状, 使其能伸入其中, 吸尽饮水。
[0042] 如图 3所示, 水箱盖 (101 ) 与凹底水箱 (110) 间, 采用铰链结合, 水箱盖 (101 ) 的前端设有箱盖锁扣(105); 水箱盖(101 )还附设有在盖子内侧上的定位短柱 (102) ; 当合上 水箱盖(101 ), 锁定水箱锁扣(105)后, 所述的定位短柱 (102)与自锁紧取液头(02)上的定位 柱孔 (6、 103)实现套合后, 由于自锁紧取液头(02)的高度超过水箱盖(101 )盖合时的高度, 这样, 水箱盖 (101 ) 盖合时通过自锁紧取液头 (02) 的锁紧盘 (11 ), 对水包(114)产生了压 力。
[0043] 如图 2所示, 水箱盖 (101 ), 对水包(114)所产生压力的传递路径为: 定位短柱(102) —定位柱孔 (6、 103) →锁紧盘 (11 ) —水包(114), 水包 (114) 受压力的影响, 把饮水压入 倒虹管(107), 由于水流进入倒虹管(107),倒虹管 (107)内的空气因被挤压,进入上三通(108) 向排气口方向移动, 当压力大于气阀簧时, 气阔球(4)受到压力的作用, 气阀球(4)被顶开, 实现自动排气。 运用这一距离差的原理, 当放下盖子扣上箱盖锁扣 (105) 时, 自锁紧取液头 (02) 中的锁紧盘 (11 ) 被压向水包 (114), 水包 (114) 在外力的影响下, 饮水压入虹吸通 道, 虹吸通道内的空气, 因受水流的挤迫, 向排气通道移动, 一旦虹吸通道内的空气被排尽, 虹吸原理就得以实现。
[0044] 换言之, 当放下盖子, 合上箱盖锁扣 (105 ) 时, 由于距离差的原因, 锁紧盘 (11 ) 下的水包 (114)会被压下 3公分左右的压缩洼陷, 这一压力的产生, 足以驱使虹吸通道中的空 气, 向气阀孔 (2) 方向移动并顶开气阀球 (4), 实现自动排气的目的。 当虹吸通路中的空气 被排尽时, 虹吸原理形成, 自锁紧取液头 (02), 就可实施对饮机的虹吸供水。
[0045] 如图 1、 2 所示, 自锁紧取液头 (02) 的部件包括: 伪三通 (7)、 锁紧簧 (8)、 止回 瓣 (9)、 弹簧腔 (10)、 锁紧盘 (11 )、 锁紧口 (12)、 密封环 (14) 及取液头(16)。
[0046] 所述的锁紧盘 (11 ) 呈 Π 形状, 锁紧盘 (11 ) 的中心, 设有弹簧腔 (10), 弹簧腔 ( 10) 的内侧, 分为不同直径二层内壁, 二内壁之间有明显的台阶。
[0047] 所述的锁紧盘 (11 ), 通过弹簧腔 (10) 中的小台阶, 套装在自锁紧取液头 (02) 上。 所述的锁紧盘(U ) 上的锁紧口 (12), 其作用有三, 其一, 与密封环 (14) 闭合后能可靠地 锁紧水包(114) 的插入口, 杜绝水包(114) 的渗漏现象, 其二, 限定锁紧盘(11 ) 的活动范 围并保证锁紧盘(11 )不会脱离自锁紧取液头(02); 其三, 由于锁紧盘(11 )及锁紧口 (12) 具有缓冲及限位的作用, 用户在操作自锁紧取液头 (02) 插入水包 (114) 时, 无须考虑插入 的力度和速度, 大大增强了操作的自由度, 可从容放心地实现操作。 [0048] 所述的弹簧腔(10)直径较大的内壁与自锁紧取液头(02)之间的空间, 是锁紧簧(8) 的安装腔(10) ; 弹簧腔(10)直径较小的内壁与自锁紧取液头(02)呈宽松的整配合, 使锁紧 盘 (11 ) 在自锁紧取液头 (02) 上, 能活动自如。
[0049] 所述的弹簧腔 (10) 靠近密封环 (14) 的端口上, 设有锁紧口 (12)。 所述的锁紧口 ( 12), 呈凹形圆环结构, 其直径及深度与密封环 (14) 的直径和高度相一致。 在锁紧簧 (8) 的弹力作用下, 锁紧盘 (11 ) 的锁紧口 (12), 与密封环 (14) 闭合, 能自动锁紧水包 (114) 的插入口, 保障使用屮的水包 (114), 不会发生渗漏的现象。
[0050] 所述的密封环 (14), 安装于吸液头 (16) 的锥头与中空圆管结合部的封环槽(13)中, 密封环(14) 的外径, 略大于锥形吸液头(16) 的锥底, 以吸液头 (16) 的锥度趋向, 设定为 密封环 (14) 的外径值, 呈自然过渡的状态, 以利吸液头 (16) 能方便地插入水包 (114) 实 施取水作业; 密封环(14)的内径要小于封环槽 (13)的直径, 以使密封环(14)能紧实地嵌装 于取液管上。
[0051] 所述的密封环(14), 作用有二, 其一是, 通过与锁紧口 (12)偶合, 锁紧水包(114) 的插入口, 使饮水不会向外渗漏; 其二是, 限定锁紧盘(11 )的活动范围, 并阻挡锁紧盘(11 ) 脱离上位取液器 (02)现象的发生。
[0052] 所述的锁紧簧 (8), 安装于直径较大的内壁与自锁紧取液头 (02) 之间形成的弹簧腔 ( 10)中; 所述的锁紧盘(11 ), 在外力和锁紧簧(8)的弹力作用下, 可在自锁紧取液头(02) 上, 在设定的范围内作垂直的运动。
[0053] 如图 3所示, 吸液头 (16) 向水包(114)吸水作业时, 是从水包 (114) 的顶部垂直插 入的,所述的吸液头(16),设置于伪三通(7)的下方,是虹吸取液机构的起始点;吸液头(16) 与伪三通 (7) 的结合部, 设有止回阀瓣 (9), 止回闽瓣 (9)的作用, 是控制饮水只能作单向的 流动, 防止发生倒虹管中的饮水因换水操作而造成的流失现象。
