Description

一种具有钛制复合内胆的保温杯及其制造工艺 技术领域
本发明涉及保温杯技术领域，尤其涉及一种具有钛制复合内胆的保温杯及其制造工艺。
背景技术
保温杯从保温瓶发展而来的，保温原理与保温瓶一样，只是人们为了方便把瓶做成杯。钛金内胆是指电热水器由含钛金属制成的内胆。这种内胆强度高、耐高温、抗腐蚀，性能稳定，分别有卧式、立式和圆柱体、立方体可供选择。
目前市场上的钛金属内胆保温杯往往结构复杂，使用价值不高，为了外观好看和不生锈，采用钛合金或不锈钢制成，钛合金价格昂贵，不锈钢没有光泽，影响外观。如中国发明专利(CN202801002U)所公开的一种钛金属双层保温杯，包括杯体和杯盖，杯体包括钛金属内胆和钛金属外壳，在该钛金属内胆和钛金属外壳之间具有一个空隙层，杯体的内胆和外壳均采用钛含量高达95％或以上的钛金属制作，空隙层内真空或空气。此种是内胆为钛金属，外壳为不锈钢材料，此两种材料采用钎焊制成，中间抽成真空，但我们知道同种材料焊接性能是最好了，但是不锈钢与钛焊接，由于材料的熔点不同，很容易产生漏气等质量问题，即使能焊接好，但焊接成本高昂，此种方法制成的保温杯也难于达到真空度的要求，从而保证不了保温的要求。钛金属保具有诸多优异性能，相比较传统不锈钢保温杯，能够大大提高保温瓶的抗腐蚀性能。
虽然上述专利的钛金属保温杯具有多种好处，但也存在不足之处，该保温杯的内胆和外壳均用钛合金制造，而钛合金价格比较高昂，如果采用铁或不锈钢制成，则缺乏金属光泽度，影响保温杯的整体美观性，如果采用不锈钢制成， 因为不锈钢耐蚀性差及含有重金属元素会影响人体的健康。
发明内容
本发明针对现有技术中生产成本高、存放时间长水质容易变差的缺点，提供了一种生产成本低、存放时间长水质不容易变质的具有钛制复合内胆的保温杯及其制造工艺。
为了解决上述技术问题，本发明通过下述技术方案得以解决：

作为优选，第二内胆层上端设有向外翻边的过渡圆弧，过渡圆弧与第二内胆层为一体式结构，第一内胆层的上端部设在过渡圆弧内。将内胆本体上端设为过渡圆弧，提高内胆本体上端部的圆滑度，方便用户使用。
作为优选，第一内胆层的上端和第二内胆层的上端均设有向内胆本体中部延伸的半圆弧，第一内胆层的半圆弧和第二内胆层的半圆弧组合形成过渡圆弧。 过渡圆弧通过第一内胆层和第二内胆层分别加工的半圆弧形成，保证内胆本上端部的圆滑度，同时节省了工艺的制造成本。
作为优选，内胆本体上端设有杯口，杯口包括由下至上依次设置的第一倾斜段、第一竖直段、第二倾斜段、第二竖直段，内胆本体、第一倾斜段、第一竖直段、第二倾斜段、第二竖直段为一体式结构，第一倾斜段向内胆本体内部方向弯折设置，第二倾斜段向内胆本体外部方向弯折设置。通过第一倾斜段和第一竖直段设置减小杯口的直径，增强保温杯内胆本体的保温效果，通过第二倾斜段和第二竖直段的设置，增大杯口上端的直径，在喝水时，增大水流的速度，方便用户的使用。
作为优选，第一竖直段的圆柱直接小于第二竖直段的圆柱直径，第二竖直段的圆柱直径小于内胆本体的圆柱直径。
作为优选，第一底层的厚度与第一内胆层的厚度相同，第二底层的厚度与第二内胆层的厚度相同。方便第一内胆层和第一底层以及第二内胆层和第二底层的激光焊接或者钎焊，降低生产成本，同时保证内胆本体的密封性。
作为优选，外壳的上端设有向第一内胆层方向弯折的连接片，连接片的端部与第一内胆层的端部固定连接。外壳和内胆本体之间抽出空气形成真空，方便对内胆本体内的液体进行保温。
