具体实施方式
下面结合附图及实施例对本实用新型作进一步描述：
参见图1至图4所示，一种车载电热咖啡机，包括煮水杯11、咖啡斗13、蒸馏杯19和杯盖21，煮水杯11上端与蒸馏杯19下端连接，咖啡斗13设置在煮水杯11杯口处，蒸馏杯19内设有蒸馏管20，蒸馏管20下端蒸馏杯19底部通向咖啡斗13，蒸馏管20上端通向蒸馏杯19上部，杯盖21与蒸馏杯19上端连接；所述煮水杯11底部设有加热板8，加热板8底部设有温控器6，温控器6包括感温面23和接线端子28，感温面23与加热板8底面贴合，接线端子28串联在加热板驱动电源线上。
所述温控器6外侧设有安装架25，加热板8底部对应安装架25设有支撑件，安装架25与支撑件通过连接件固定连接。所述支撑件为螺杆7，连接件为螺母24，螺杆7一端与加热板8底部焊接固定，螺杆7另一端穿过安装架25与螺母24连接，以将温控器6压紧在加热板8底部。
所述温控器6为自动复位式温控器，其起跳温度为100摄氏度(但不限于此温度起跳的温控器)。
所述煮水杯11底部敞开，煮水杯11下端内侧设有凸缘30，加热板8通过耐高温支架5压紧在凸缘30底部，其中，加热板8与凸缘30之间设有第一密封圈9，耐高温支架5外周与煮水杯11下端内侧螺纹配合。
所述煮水杯11底部还设有杯座和控制电路板3，控制电路板3设置在杯座内，控制电路板3设有所述加热板驱动电源线；所述杯座包括上盖4、外壳2和底盖1，上盖4中心与所述耐高温支架5中心通过一螺丝27连接，外壳2套设在上盖4及底盖1外周；所述煮水杯11下端设有上限位台阶10，底盖1对应外壳2下端设有下限位台阶18，上盖4和底盖1通过螺钉连接，外壳2压接在上限位台阶10和下限位台阶18之间。
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。
所述煮水杯11和蒸馏杯19的杯壁均为双层结构，且层内为真空隔热层44/46。其中，所述煮水杯11和蒸馏杯19外壁分别对应其真空隔热层44/46设有第一抽真空孔位29和第二抽真空孔位31。所述第一抽真空孔位29设置在煮水杯11下端的上限位台阶10表面，以被杯座的外壳2遮盖；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，温控器6起跳，使得加热板驱动电源线与电源断开连接，避免加热板8温度继续升高，从而避免干烧活着避免煮水杯11内压力不断升高，以致爆炸的危险。
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。
