具体实施方式
下面将结合本实用新型实施例中的附图，对本实用新型实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本实用新型一部分实施例，而不是全部的实施例。基于本实用新型中的实施例，本领域普通技术人员通过简单变形所获得的所有其他实施例，都应属于本实用新型保护的范围。
如图1-图3所示，本实施例所描述的防烫保温暖手杯，包括杯体1、杯口2和杯盖，其特征在于，杯盖包括外盖3和外盖3内设有的盖胆4，外盖3和盖胆4连接，且外盖3和盖胆4之间形成有封闭空腔5，空腔5内设有导热介质6，所述杯口2套设有密封套7。
所述杯口2和杯盖螺纹14连接，所述杯体1为具有真空内腔的双层结构。所述杯口2和杯盖的连接方式也可是其他现有的卡接等方式。杯盖也是空腔5接近真空的双层结构，能使得杯内的水温长时间保持。
所述导热介质6为导热液或导热粉末，所述导热液的沸点为30-100度，当杯体1和杯盖倒置或倾斜时，导热介质6能同时接触盖胆4顶部和外盖3顶部。
所述导热介质6在杯体1和杯盖正立放置时聚集在空腔5底部，且导热介质6的表面高度低于盖胆4顶部的高度，杯体1是双层真空结构，杯盖是接近真空双层结构，能长久的保持杯内的液体温度；
所述导热介质6在杯体1和杯盖倒立或倾斜放置时聚集在空腔5顶部，且导热介质6的表面最大高度等于或高于盖胆4顶部的最低高度。
所述导热介质6为导热液，所述导热液的沸点为30-100度，当杯体1和杯盖倒置或倾斜时，导热介质6能同时接触盖胆4顶部和外盖3顶部。使用时，打开杯盖，将热水倒入杯体1内，拧紧杯盖，竖直正向放置时，杯盖空腔5内的导热液或导热粉末不与盖胆4及杯内的高温液体接触，长时间保持水温；当急需喝水或需要通过杯盖取暖时，将水杯倒置放置，导热液流到杯盖空腔5顶部与盖胆4接触，吸收热杯体1内液体的热量并汽化后，充满内腔，使得杯体1内的液体热量依次通过盖胆4顶部、导热液气体传到外盖3上，能迅速减低杯体1液体温度，方便饮用，或方便外盖3暖手。
所述密封套7为环型且密封套7设有一圈环形插槽8，杯口2插入在插槽8内。优选的密封套7为截面为n型的硅胶套，能密封杯盖和杯口2。
所述杯口2侧壁设有限位槽15，所述密封套7的插槽8内设有限位棱16，限位棱16与限位槽15插接。用于限制密封套7从杯口2脱落。
所述杯口2顶部凹陷形成有密封槽17用于容纳密封套7，使得密封套7表面和杯口2表面齐平。
所述外盖3设有抽气孔9，抽气孔9通过铆钉10密封固定，铆钉10和抽气孔9之间设有密封圈11。
杯盖内的空腔5注入导热液后抽真空的具体步骤是：导热液具体在杯盖空腔5底部，先加热杯盖，使得导热液汽化，体积膨大，将空腔5内的空气从抽气孔9排出，抽气孔9出设置测温头感知导热液气体的到来后，然后用铆钉10密封固定抽气孔9，且之间用密封圈11密封。
所述外盖3设有凹槽12，所述抽气孔9设置在凹槽12内，优选的，还可以 在铆钉10和凹槽12之间的空隙设有焊接层或胶层，加强密封性。所述外盖3顶部连接有顶盖13。顶盖13遮蔽凹槽12，起到美观作用。
在其他实施例中，所述导热介质6为导热粉末，导热粉末包括但不限于金属粉和/或沙土，金属粉包括单一金属粉末、合金粉末或具有金属性质的某些难熔化合物粉末。
所述导热粉末包括黄铜粉和铁砂，且黄铜粉和铁砂的重量比例为1:3-3:1。
使用的时候，杯内倒入热水或热饮，竖直正立的放置杯身，空腔5的导热粉末聚集平铺在空腔5底部，不与杯盖的盖胆4顶部和热源接触，杯内热水得以长时间保温；当急需喝水或需要通过杯身取暖时，将杯身翻转，杯底朝上竖直放置，导热粉末流动到杯盖的空腔5顶部，与杯盖的盖胆4顶部和热源接触，使得杯体1内的液体热量依次通过盖胆4顶部、导热粉末传到外盖3上，能迅速减低杯体1液体温度，方便饮用，或方便外盖3暖手。
生产加工时，抽真空工艺很多，工艺大体分为抽气、封焊、冷却等环节，在空腔5中加入导热粉末，利用现有的抽真空工艺直接加工就行，相比空腔5空置的保温杯抽真空，抽真空工艺没有变化，也不受影响。空腔5抽真空过程简单、成本低，抽真空后空腔5真空程度高保温效果好。
黄铜粉粒径非常小，接触面积更高，更高效的导热。但是黄铜粉单独加入内腔中，流动性较差，容易堆积在内腔某处，需要加入铁砂或是其他流动性强的颗粒与黄铜粉混匀，使得混合后的粉末既导热效率高又流动性强。
