[0044] 第二步、 然后, 按下按钮 21, 控压机构 2将气压源 11的高压气体减压为冲泡压 力气体进入储水器 3 ; 冲泡压力水继而进入咖啡放置腔 451中与咖啡溶合萃取;
[0045] 第三步、 然后, 咖啡浆进入背压谐振机构 4, 首先到达的咖啡浆从导流板 44的 导流孔 443流下, 进入环形空间 444, 此时背压盒体 40的盒底面 401被胶体环 43压 住; 此时设置了一个谐振针 42, 放置在盒底面 401上, 胶体环 43与谐振针 42接触 之处设置有谐振凹槽 431, 扣在谐振针 42上, 构成谐振腔 425 ; 冲泡压力的咖啡 浆路经谐振腔 425时, 由于冲泡压力和谐振腔 425特殊的结构, 高频振荡后被充 分打成泡沫, 从咖啡出口 5流出。
[0046] 第三步所述导流板 44嵌入背压盒体 40时, 导流板周边 442与背压盒体 40的上内 圆壁 403吻合。
[0047] 第三步所述导流板 44下部有一下圆凸台 441, 用来卡住胶体环 43的中心圆孔
, 为其定位; 所述的背压盒体 40的下内圆壁 402与胶体环 43的胶体环外缘 432共 同构成环形空间 444。
[0048] 第二步所述的冲泡压力, 在便携式咖啡机中为 6〜 8bar压力, 在家用或台式 机中为 9~l lbar压力。
[0049] 本发明的再一种实施方法为: 将气压源 11、 控压机构 2、 储水器 3进行组合由水 泵施压, 泵压水进入咖啡放置腔 451。
[0050] 设计制造一种咖啡高倍发泡的装置, 所述装置包括一控压机构 2, 在控压机构 2 的入口处连接气压源 11, 在控压机构 2的出口处连接储水器 3 , 在储水器 3下方设 置咖啡放置腔 451, 在咖啡放置腔 451下部是背压谐振机构 4, 在背压谐振机构 4 的下部是咖啡出口 5。
[0051] 控压机构 2设有按钮 21, 按下按钮 21, 控压机构 2将高压力的气体减压为冲泡压 力进入储水器 3 ; 冲泡压力水继而进入咖啡放置腔 451中与咖啡溶合萃取; 所述 的冲泡压力, 在便携式咖啡机中为 6〜 8bar压力, 在家用或台式机中为 9~l lbar压 力。 [0052] 所述背压谐振机构 4包括导流板 44, 其上分布圆周设置的导流孔 443 ; 导流孔 44 3连通环形空间 444;
[0053] 背压谐振机构 4还包括背压盒体 40, 背压盒体 40的盒底面 401被胶体环 43压住;
[0054] 一个谐振针 42, 放置在盒底面 401之上, 胶体环 43与谐振针 42接触之处设置有 谐振凹槽 431, 谐振凹槽 431扣在谐振针 42上, 二者之间构成谐振腔 425 ; 冲泡压 力的咖啡浆在路经谐振腔 425时, 由于冲泡压力和谐振腔 425特殊的结构, 发生 高频振荡后被充分打成泡沫, 从咖啡出口 5流出。
[0055] 所述导流板 44嵌入背压盒体 40时, 导流板周边 442与背压盒体 40的上内圆壁 403 吻合; 所述导流板 44下部有一下圆凸台 441, 用来卡住胶体环 43的中心圆孔, 为 其定位;
[0056] 所述的背压盒体 40的下内圆壁 402与胶体环 43的胶体环外缘 432共同构成环形空 间 444。
[0057] 所述储水器 3下部有储水器锁扣 35与背压谐振机构 4的背压外壳 45上的背压锁扣 453扣合, 将咖啡包 8锁在咖啡放置腔 451上;
[0058] 所述咖啡放置腔 451由放置腔托盘 458支撑, 其下是咖啡浆空间 454, 由咖啡浆 过孔 452流下的咖啡浆储存在其间。
[0059] 所述咖啡出口 5处设置出口滤网 51, 以及防溅口 52, 使从出浆口 407流出的咖啡 浆有序第流入咖啡杯; 所述控压机构 2的顶部设置控压机构盖板 21 ;
[0060] 背压盒体 40和背压外壳 45之间设置背压盒体密封圈 491 ;
[0061] 导流板 44上面设置导流板滤网 492。
[0062] 本发明再一种实施方式: 将气压源 11、 控压机构 2、 储水器 3进行组合由水泵施 压, 泵压水进入咖啡放置腔 451。
[0063] 气压源包括二氧化碳、 高压蒸汽。 如果是市场上通用的饮用水用水泵加压, 等 于将气压源、 控压机构、 储水器进行组合, 本高倍发泡装置也适合。 此时的结 构为: 将气压源、 控压机构、 储水器进行组合由水泵施压, 泵压水进入咖啡放 置腔。
[0064] 袖珍二氧化碳气罐的体积最很小, 对于便携式咖啡机很适用, 而且其相对水泵 来说无噪音产生。 [0065] 另外, 利用二氧化碳的好处在于, 咖啡口感来自于咖啡豆烘烤后产生的二氧化 碳气体含量。
[0066] 从图 4中看出, 用本发明可以打出高倍的泡沫, 配以不同的出口滤网, 可以得 到口味不同的起泡咖啡。
[0067] 图 7中, 咖啡包 8置于咖啡放置腔 451之上, 咖啡浆经过谐振针 42和胶体环 43之 间的谐振腔 425时, 被激烈的振荡, 将咖啡浆谐振为雾化起泡, 产生大量的泡沫 。 本发明通过近百次的试验, 确定了控压机构 2减压后的二氧化碳气体压力为 7 左右最佳; 确定了谐振针 42和胶体环 43之间的谐振腔 425的最佳几何形态, 由此 , 本发明取得了预料不到的技术效果, 咖啡发泡率发生“量”的变化, 超出申请 人预期的想象。
[0068] 图 8中, 咖啡出口 5处设置的第二出口滤网 54为一兜状, 以及第二防溅口 53也为 一兜状。
[0069] 除了图 8所示第二实施例, 在咖啡出口 5处可以设置许多不同的出口滤网, 以及 防溅口的形态, 在此不一一例举。
[0070] 以上内容仅为本发明的较佳实施例, 对于本领域的普通技术人员, 依据本发明 的思想, 在具体实施方式和应用范围上均会有改变之处, 本说明书内容不应理 解为对本发明的限制。
