Description

一种金属膜加热杯 技术领域
本实用新型涉及电子加热烟具技术领域，具体涉及一种金属膜加热杯。
背景技术
随着新型烟草产品在世界范围内的兴起，尤其是在日韩地区销量的快速增长，低温不燃烧烟具的加热技术已成为行业内的研究热点。目前，市场上主要的加热技术有MCH陶瓷加热技术、加热膜或电热丝缠绕管体加热技术。其中，MCH陶瓷加热技术由于以氧化铝等陶瓷材料做基材，制成杯形时，为了易加工成型且保持加热杯坚固性，一般壁厚较厚且基材密度较大，导致整个发热体重量较重，增加加热能耗且不利于产品隔热；而加热膜和电热丝缠绕管体加热技术，需要其他材料制成杯型，与其缠绕包裹使用，该技术由于发热元件与被缠绕基材物理形式上分离，热转换效率较低，影响加热速度，同时增加了产品组装难度。
发明内容
本实用新型的主要目的在于提出一种金属膜加热杯，通过将金属膜发热涂层固结附着于覆有绝缘层的金属杯体表面形成加热杯，以解决现有的杯体加热技术所存在的上述技术问题。
本实用新型为达上述目的提供以下技术方案：
一种金属膜加热杯，包括金属杯体以及附着于所述金属杯体表面的发热层；所述发热层包括：附着于所述金属杯体表面的绝缘层、附着于所述绝缘层表面的至少一段金属膜发热涂层以及附着于所述金属膜发热涂层表面的保 护层；其中，当所述绝缘层表面具有两段以上金属膜发热涂层时，各金属膜发热涂层分别独立地与加热控制电路连接，实现分段加热控制。
本实用新型上述技术方案所提供的金属膜加热杯，通过高温烧结工艺，将金属膜发热涂层固结附着于覆有绝缘层的金属杯体表面，达到MCH陶瓷一体成型工艺标准，金属膜发热涂层通电后即可发热，金属膜发热涂层与金属杯体的表面间热阻小，热效率高，热辐射低，有利于降低烟具外壳机身温度，且组装方便；同时由于采用金属材料制作加热杯的杯体，因此杯体的杯壁较薄，重量轻，能够减少加热能耗，增加烟具续航时间；另外，采用多段金属膜发热涂层加热技术，能够实现对气溶胶材料不同位置加热温度的精准控制，延长抽吸时间，醇化口感。

在另一些实施例中，如图5所示，金属杯体10的底部是密封的，金属杯体内设置有防止固体被加热物下沉至杯底的支撑部12，支撑部12为一个或 多个，主要设置在杯体底部，呈凸出状，可将被加热物抬离底部约0.5～2mm。当用于加热烟丝时，如图5所示的箭头线代表了气流方向。
在一些实施例中，采用具有TCR特性的电阻浆料制作金属膜发热涂层30，从而，在加热杯的应用中，可以将加热杯与锂电池和电路板连接，通过电路板与软件程序监控金属膜发热涂层的电阻值变化，实现加热杯的加热温度控制。
在本实用新型的加热体的另一些应用实例中，可以将加热杯与温度传感器、锂电池和电路板连接，通过温度传感器实时获取加热杯的温度并反馈至电路板，通过电路板对加热杯的加热温度进行控制。
以上内容是结合具体的优选实施方式对本实用新型所作的进一步详细说明，不能认定本实用新型的具体实施只局限于这些说明。对于本实用新型所属技术领域的技术人员来说，在不脱离本实用新型构思的前提下，还可以做出若干等同替代或明显变型，而且性能或用途相同，都应当视为属于本实用新型的保护范围。
