下面结合附图和具体实施例对本发明进行详细地说明。
附图说明
图1为本发明实施例1的发热体结构示意图。
图2为本发明实施例2的发热体结构示意图。
具体实施方式
本实施例是一种发热体,并提供这种发热体的制备方法。如图1所示,本实施例的发热体是一种用于电子烟雾化器中的发热器,它是一种圆柱形形状的发热体。包括设置在中心的圆柱体形状的基体1,在基体1表面设置的膜状电阻,它是设置在致密陶瓷基体表面的具有一定电阻的膜状物,它的两端焊接电极3加电后发热,成为发热材料2,在发热材料2和基体1组合体外,还可以套上一层第二基体5,第二基体5与基体1配套,第二基体镶嵌在基体1上,另外在第二基体5外还包裹一层由微孔材料比如微孔陶瓷材料的导液体4,可以将需要雾化的液体,如在电子烟中的烟油,在加湿器中的水等,通过导液体4可以源源不断导入液体,本实施例中,在雾化器中,将导液体4的一部份浸入到电子烟的油杯中,可以将油杯内的烟油导入到第二基体5表面。由于电极3两端加电,发热材料2发热,而作为良导热材料的第二基体5也将是高温,因此,烟油将会在微孔材料中导入到致密材料的基体上雾化,本实施例中,选择致密陶瓷材料做基体和第二基体,选择微孔陶瓷材料做导液体,利用电阻浆液做成发热的发热体。目前,电阻浆液在PCB板或者其它平面上形成的膜,一般是用于导电的,本实施例,根据需要在致密陶瓷的基体表面,根据需要形成不同形状的膜状电阻,在两端焊接电极形成电热器,电阻浆液在PCB板或者其它平面上形成的膜不再是仅仅用于导电(导线)的作用,在致密陶瓷基体的表面还是做加热材料,也就是电热器用。
本实施例中,基体1和第二基体5是一种致密陶瓷体的材料,实践上,可以是其它形状的陶瓷材料,如完整连续片状、中间有缺失的片状、边缘有缺失的片状、螺旋片状、方形片状、圆形片状或其他部分连续的片状结构的至少一种。致密陶瓷体的材料说明如下:致密陶瓷体的材料为二氧化硅、氧化铝、碳化硅、氮化硅或其他陶瓷材料的一种或者几种的混合,这在实践中,目前陶瓷的生产工艺非常成熟,可以做成不同形状的陶瓷体。
本实施例中发热材料2是一种加电以后,由于有电阻可以发热的电阻浆液材料,本实施例中是在基体表面通过印刷等工艺将电阻浆料形成具有一定电阻的膜状物,在膜上焊接两根导线做电极形成加热器。实践中,电阻浆料可以有很多选择,制备工艺也可以有很多成熟的工艺。
目前,发热材料通过印刷、涂覆、浸泡或喷涂等方式的至少一种方式固定在致密陶瓷体的表面形成膜状物,如厚膜、薄膜等。发热材料的固定形状为S形、直线形、折线形、波浪形、锯齿形、螺旋形、圆形、方形或其他形状的至少一种。发热材料的原料为电阻浆液,即钯银浆料、不锈钢浆料或钨浆料等电阻浆料的一种或者几种浆料的混合。电极材料为镍、不锈钢或银等导电材料的至少一种。电极的形状为丝状、片状或圆柱体状的至少一种。电极材料固定在致密陶瓷上且和发热材料结合。在实践中,两个电极之间的电阻可以通过调整膜状物的形状和浆料的比例,调整到0.1至19欧姆。
本实施例中,用于做导液体4的材料是一种微孔陶瓷材料,在其中的微孔内可以导油和水等液体,多孔陶瓷体和致密陶瓷体通过烧结或镶嵌等方式固定在一起。多孔陶瓷体材料为二氧化硅、氧化铝、碳化硅、氮化硅或其他陶瓷材料的至少一种。多孔陶瓷体的结构为球体、长方体、圆柱体、完整连续片状、中间有缺失的片状、边缘有缺失的片状、螺旋片状、方形片状、圆形片状或其他部分连续的片状结构。
本实施例的电子雾化器发热体的制备过程如下:
S1、采用二氧化硅、氧化铝、碳化硅或者氮化硅中的一种或者数种陶瓷材料混合制作致密陶瓷作为基体。
S2、将钯银浆料、不锈钢浆料或钨浆料中的一种或者数种混合浆料用厚膜印刷的方式印刷基体表面形成膜状电阻;本实施例中,使用钯银浆料采用印刷的工艺,在致密陶瓷表面形成膜状物。
S3、将镍丝或者不锈钢丝或者银线作为电极导线用钎焊的方式固定在基体上,本实施例中,镍丝或者不锈钢丝或者银线与固定在基体表面的膜状电阻两端与电极分别接触良好。
S5、放入高温炉,在600-1000℃下保温40-80分钟;本实施例中,温度或以保持在800℃左右和1小时左右,当然,温度越高,保持时间可以减小,在实践中可以把握火候。
S6、加入到模具中,并将二氧化硅、氧化铝、碳化硅或氮化硅中的至少一种多孔陶瓷材料压入模具;本实施例中选择氧化铝作为多孔陶瓷的原材料。
S7、再次放入高温炉,本实施例中,温度或以保持在800℃左右和1小时左右,当然,温度越高,保持时间可以减小,在实践中可以把握火候,就可以制备好一个发热体了,该发热体中,可以利用外表上的多孔陶瓷体将烟油导入雾化。
实施例2,本实施例是一种用于加湿器中的的加热体及其制备方法。如图2所示,本实施例的发热体中包括一块陶瓷片的基体1,在基体上通过印刷工艺在基体上形成的膜状物做发热材料2,在基体1上印刷了电阻浆液后,再用一层微孔陶瓷形成导液体。
本实施例的制备方法如下:
S21、采用二氧化硅制作致密陶瓷片做基体;
S22、将钯银浆料用厚膜印刷的方式印刷致密陶瓷片的表面形成膜状电阻。
S23、将镍丝作为电极导线用钎焊的方式固定在致密陶瓷片上,与膜状物两端接触良好。

出炉就形成了如图2所示的发热体。
