具体实施方式
下面参考附图并结合实施例对本实用新型进行详细说明。需要说明的是，在不冲突的情况下，以下各实施例及实施例中的特征可以相互组合。
如图1-5所示，本实用新型其中一个实施例中的咖啡机的咖啡粉压紧装置包括：固定在机身上的过滤器组件支撑架11、过滤器组件17、活动压块5以及第一密封圈6，其中，过滤器组件支撑架11上设置有容纳腔11a，所述容纳腔11a具有位于侧壁的侧开口11b和位于顶部的顶开口11c，所述过滤器组件17可从所述侧开口11b放入所述容纳腔11a中和从所述容纳腔11a中取出。较优地，所述容纳腔11a两个相对内壁上设置有沿所述过滤器组件17插入或取出方向延伸的滑槽11d，方便过滤器组件17导入和定位。较优地，所述侧开口11b的顶部设置有刮粉片10，所述刮粉片10具有至少一个用于刮落咖啡粉的刮粉面，当过滤器组件17放入容纳腔11a时，通过刮粉片10的刮粉面移除过滤器组件17中多余的咖啡粉。所述刮粉片10与所述容纳腔11a的侧壁为一体结构，或者，所述刮粉片10为一单独零件，所述刮粉片10固定在所述容纳腔11a的侧壁上。
如图5所示，本实施例中的所述过滤器组件17包括过滤器主体12、过滤片13、第二密封圈14和增压机构，其中，所述过滤器主体12上设置有腔体12a和咖啡流出口12b，所述 腔体12a的底面设置有咖啡液出口12c，所述过滤片13设置在所述腔体12a的底部，所述过滤片13与腔体12a的底面，所述增压机构设置于所述咖啡液出口12c与所述咖啡流出口12b之间设置有第二密封圈14，所述过滤片13用于阻止咖啡粉通过，防止咖啡水在流出的过程中咖啡粉堵塞增压机构。增压机构设在咖啡液出口12c和咖啡流出口12b之间，用于增加酿造腔B的压力。增压机构既可以采用节流孔通过小孔限流的方式也可以采用阀的方式，本实例中的增压机构阀由堵块15和弹簧16组成。
继续参见1-4，所述活动压块5装在固定在过滤器组件支撑架11上方的活动压块支撑架9上，所述活动压块5的下端位于所述容纳腔11a的顶开口中，所述活动压块5可在高度较高的第一位置与高度较低的第二位置之间上下升降运动，所述活动压块5的下端设置有向下突出的挤压部5a。所述第一密封圈6固定在所述活动压块5下端，所述第一密封圈6的外周面上设置有与所述腔体12a的开口端配合的限位台阶。当然，所述第一密封圈6也可以设置在所述腔体12a开口端。
参见图3，当所述活动压块5位于所述第一位置时，过滤器组件17可自由取出和放入容纳腔11a。参见图4，当所述活动压块5由驱动装置从第一位置运动至第二位置时，且所述过滤器组件17位于所述容纳腔11a中时，由所述活动压块5、所述第一密封圈6和所述过滤器组件17一起形成酿造腔B，由于活动压块5的下端设置有向下突出的挤压部5a，所述挤压部5a伸入所述腔体12a内，将咖啡粉压紧，从而解决了现有咖啡粉预压紧方式存在的松紧程度不容易得到控制和费力的问题。较优地，当所述活动压块5位于所述第二位置且所述过滤器组件17位于所述容纳腔11a中时，所述挤压部5a下端面至所述腔体12a开口端的端面之间的距离为5mm～10mm。
在一个实施例中，所述活动压块5上设置有沿轴向延伸的进水孔51，在所述挤压部5a的下方设置有拦网30，所述拦网30的周缘固定在所述第一密封圈6的下端上，通过拦网30防止咖啡粉进入进水孔51中。
驱动活动压块5的驱动装置可以是液压驱动，参阅图6，活动压块5与入水头2通过密封元件3、密封元件4形成液压腔A，咖啡机包括有水泵19、锅炉20、管道系统21和液压控制装置22和单向阀23，水泵19工作时产生压力水流通过管道系统接入液压腔A驱动活动压块5运动，将咖啡粉压紧。活动压块5运动到压紧位置后停止移动，这时水路系统压力开始增大，当压力开始大于单向阀23设定的压力值时，单向阀23接通，热水通过进水孔51进入酿造腔B制作咖啡饮品。释放液压腔A内的液体，活动压块5能在弹簧8的推力作用下回 复到起始位置。在其他实施例中，驱动活动压块5的驱动装置也可以是机电驱动，参阅图7，活动压块5采用机电驱动装置驱动，活动压块5运动至压紧位置后，水泵19开始工作，酿造咖啡饮品。
本实用新型实施例的咖啡机的咖啡粉压紧装置的工作原理如下：
第一步：在过滤器组件17的腔体12a内装入足量的咖啡粉，并将其沿着滑槽11d插入到酿造位置，刮粉片10将装载过量的咖啡粉移除；
第二步：通过液压驱动，或者机电驱动活动压块5朝向过滤器组件支撑架11运动，实现自动压粉，同时活动压块5、第一密封圈6和过滤器组件17一起形成封闭的酿造腔B；
第三步：向进水孔51注入压力热水流，该压力热水流进入酿造腔(B)制作咖啡饮品，设置在酿造腔B与咖啡出口间的增压装置增加酿造咖啡的压力；
第四步：咖啡饮品制作完成后，水泵19停止工作，液压控制装置22接通管路释放液压腔A的压力，活动压块5在弹簧力的作用下回复至初始位置，或者驱动机构驱动活动压块5回复至初始位置，最后取出过滤器组件17，将咖啡粉倒掉完成整个制作咖啡饮品的过程。
以上所述实施例仅表达了本实用新型的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对本实用新型专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本实用新型构思的前提下，还可以做出若干变形和改进，这些都属于本实用新型的保护范围。
