所述耐高温支架5中心设有中心螺母26，上盖4设有中心孔，螺丝27从下至上穿过上盖4的中心孔与耐高温支架5的中心螺母26连接。
所述蒸馏杯19的杯壁为双层结构，蒸馏杯19的杯壁内部为第二真空隔热层46，蒸馏杯19外壁对应第二真空隔热层46设有第二抽真空孔位31，所述蒸馏杯19外周设有装饰圈17，装饰圈17遮盖在所述第二抽真空孔位31外。所述蒸馏杯19下端外周设有锥形台阶面18，第二抽真空孔位31设置在锥形台阶面18外侧；所述装饰圈17为硅橡胶圈，其套设在锥形台阶面18外、并遮盖第二抽真空孔位31。鉴于抽真空时需要在杯的外表面开设抽真空孔位，抽完真空后，再将抽真空孔位封堵，但是由于封堵孔位时将会出现毛糙，以致影响杯体外观，所以，本实用新型的煮水杯11和蒸馏杯19外分别借助杯座外壳2和采用装饰圈17将其表面的抽真空孔位处毛糙遮盖。
另外，由于装饰圈17为硅橡胶圈，当蒸馏杯19摔下时，硅橡胶圈起到缓冲作用，大大降低摔破的几率。再有，装饰圈17与蒸馏杯19配合处具有一定的锥度，所以能防止装饰圈17掉出。
所述煮水杯11上端与蒸馏杯19下端螺纹连接，蒸馏杯19上端与杯盖21螺纹连接，其中，煮水杯11上端和蒸馏杯19上端均设有外螺纹，煮水杯11上端与蒸馏杯19下端之间设有第二密封圈15。当煮水杯11上端与蒸馏杯19上端设计成大小一致是，当取走蒸馏杯19和咖啡斗13后，可以将杯盖21与煮水杯11上端开口连接，即可利用煮水杯11烧水，见图4所示。
所述蒸馏杯19中部外周设有凹弧面，以形成握持部。
所述蒸馏管20上端设有盖帽32，蒸馏管20与盖帽32之间留有间隙。
所述咖啡斗13底部设有蒸气管12，蒸气管12连通咖啡斗13和煮水杯11内部，咖啡斗13内底部和顶部分别设有下滤网14和上滤网16。
所述杯盖21包括杯盖本体43、金属外套42和硅胶阀片41，金属外套42设置在杯盖本体43外，杯盖本体43顶面延伸出围板39，围板39顶部与金属外套42之间设有第三密封圈38，使得杯盖本体43顶部通过围板39与金属外套42内顶部共同围成泄压腔35。硅胶阀片41设置在杯盖本体43内顶面。所述硅胶阀片41表面设有第一泄压孔36，杯盖本体43顶面设有第二泄压孔37，金属外套42顶面设有第三泄压孔34，第一泄压孔36与第二泄压孔37错开，第二泄压孔37与第三泄压孔34错开。所述硅胶阀片41顶面设有环形凸筋40，环形凸筋40包围在第一泄压孔36和第二泄压孔37外。
本实用新型的工作原理是：参见图3所示，使用时，将蒸馏杯19和咖啡斗13取 下，往煮水杯11内放入水C，以及往咖啡斗13内放置咖啡粉H，然后，将蒸馏杯19和咖啡斗13与煮水杯11连接。接通电源，加热板9在控制电路板3设定程序下启动，使煮水杯11内的水C烧开后产生大量水蒸汽D。由于煮水杯11与蒸馏杯19连接处密封，所以水蒸汽D只能经蒸汽管12往咖啡斗13内流动，经过高温水蒸汽D处理的咖啡粉形成香浓的咖啡液E经整流管流入蒸馏杯19内。由于存放在蒸馏杯19内的咖啡液E温度较高，仍能释放出较多的水蒸汽F，水蒸汽F依次经过第一泄压孔36、第二泄压孔37进入泄压腔35泄压后从第三泄压孔34排出。当煮水杯11内的水烧干后，加热板8温度将会高于100摄氏度，热敏电阻7将温度信号反馈给控制电路板3，以通过控制电路板3及时停止加热板8工作。
另外，杯盖21还具有防漏水功能，其由于硅胶阀片41的第一泄压孔36孔径很小，硅胶阀片41顶面的环形凸筋40使硅胶阀片41与杯盖本体43内顶面之间具有一定的形变间隙。当连接有所述杯盖21的煮水杯11或蒸馏杯19倾侧时，杯内的液体还未完全进入第一泄压孔36，在液体的压力下，硅胶阀片41往杯盖本体43内顶面方向形变、并遮盖第二泄压孔37，从而阻塞了杯盖21与外界连通的通道，起到防止漏水的作用。
实施例二，与实施例一的不同之处在于：参见图5所示，所述煮水杯11的杯壁设有泄压阀50，煮水杯11的杯壁为双层结构，其中，杯壁外层为硅胶套60。
上述硅胶套60上端延伸至煮水杯11上部，硅胶套60下端套设在杯座外，以充当杯座外壳(外壳取消)。
上述硅胶套60遮盖在泄压阀50外，由于硅胶套60具有一定的弹性，当煮水杯11内部压力过大而需要泄压阀50泄压时，硅胶套60对应泄压阀50处将会鼓起，以提示用户煮水杯11内部压力过大，被排出的高温气体会先进入硅胶套60与杯壁外层之间的间隙，以防高温气体直接排出杯体外，容易烫伤用户，还起到保护煮水杯11；而且，这里的硅胶套30具有隔热、保温作用。
