本申请实施例涉及电子技术领域,尤其涉及电子雾化装置及温控方法。
现有的电子雾化装置的发热体可分为两种,陶瓷发热体及棉芯发热体,二者都是通过电阻发热来产生热量,使得雾化元件中的液体雾化,一旦发热体生成的雾化温度过高,不仅仅会影响用户的体验,甚至还会危害用户的人身安全。例如,当出现发热体温度过高时,一是会导致发热体的寿命缩短甚至失效,二是雾化温度过高时,发热体会产生有害的成分(例如重金属或其他有机物质等的增加),对人体造成危害。
就现在的技术水平而言,对发热体生成的雾化温度的测试技术,属于一个技术痛点。目前的测温技术,例如电阻温度系数(temperature coefficient of resistance,简称TCR)测温技术,其通过材料本身的电阻温度系数,监控不同温度下的阻值,从而得出相应的温度。其存在测量温度的精度低和反馈速度慢等缺点。

为使本申请实施例的目的、技术方案和优点更加清楚,下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
为便于对本申请实施例的理解,下面将结合附图以具体实施例做进一步的解释说明,实施例并不构成对本申请实施例的限定。
针对背景技术中所提及的技术问题,本申请实施例提供了一种电子雾化装置,具体参见图1所示,图1为本申请实施例提供的一种电子雾化装置结构示意图,该装置包括:电子雾化信息控制子装置10以及电子雾化信息生成子装置
20。其中,电子雾化信息生成子装置20以可拆卸的方式与电子雾化信息控制子装置10连接。
具体地,电子雾化信息控制子装置10用于为电子雾化信息生成子装置20供电;
电子雾化信息生成子装置20通电后,生成热电势;
电子雾化信息控制子装置10,还用于周期性地采集电子雾化信息生成子装置20生成的热电势;当根据热电势确定电子雾化信息生成子装置20的温度高于第一预设温度阈值时,生成温度控制策略,并根据温度控制策略,调控电子雾化信息生成子装置20的温度至第一预设温度阈值以下。
在一个具体的实施例中,本申请实施例通过电子雾化信息控制子装置10为电子雾化信息生成子装置20供电,电子雾化信息生成子装置20参照热电偶原理,可以在电子雾化信息控制子装置10为自身供电后,产生热电势。
那么,电子雾化信息控制子装置10则用于周期性采集电子雾化信息生成子装置20生成的热电势。
并且,在电子雾化信息控制子装置10的内部存储有热电势与温度之间的映射关系。例如,以映射关系表的形式进行存储。
因此,在电子雾化信息控制子装置10采集到热电势后,可以将采集到的热电势与内部存储的热电势与温度之间的映射关系表中的每一个热电势进行比对,进而确定与之对应的温度数据。
一旦确定温度数据高于第一预设温度阈值,则需要生成温度控制策略。并根据该温度控制策略,调控电子雾化信息生成子装置20的温度至第一预设温度阈值以下。
在一个可选的实施例中,电子雾化信息控制子装置10可以以脉冲宽度调制形式间歇性为电子雾化信息生成子装置20供电。
例如采用方波形式供电,在供电过程中,因为脉冲方波存在高电平和低电平两种情况。那么,在方波处于高电平状态时,电子雾化信息控制子装置10为电子雾化信息生成子装置20供电。在方波处于低电平状态时,实际上电平信号为“无效”信号,并不能够为电子雾化信息生成子装置20供电。此时,电子雾化信息控制子装置10则可以利用这个间隙采集电子雾化信息生成子装置20所产生的热电势。
进而,再根据热电势确定与之对应的温度数据,然后再确定当前的温度数据是否已经超过第一预设温度阈值。如果已经超过,则生成相应的温度控制策略。
可选地,温度控制策略可以包括但不限于如下两种策略:
将电子雾化信息生成子装置20提供的供电功率降低至小于或者等于预设功率阈值;
或,直接断开对电子雾化信息生成子装置20提供供电的供电电源。
可选地,温度控制策略的选择,可以根据实际情况来确定。例如,在另一个可选的实施例中,当根据热电势确定电子雾化信息生成子装置20的温度高于第一预设温度阈值,且低于或等于第二预设温度阈值时,将电子雾化信息生成子装置20提供的供电功率降低至小于或者等于预设功率阈值。
或者,当根据热电势确定电子雾化信息生成子装置20的温度高于第二预设温度阈值时,直接断开对电子雾化信息生成子装置20提供供电的供电电源,其中,第一预设温度阈值小于第二预设温度阈值。
也即,如果根据当前采集的热电势确定电子雾化信息生成子装置20的温度高于第一预设温度阈值,但是小于或者等于第二预设温度阈值,那么可以通过电子雾化信息生成子装置20提供的供电功率,调整电子雾化信息生成子装置20的温度至第一预设温度阈值以下。
然而,也有可能在某一次采集热电势后,根据热电势确定的当前温度已经超过第二预设温度阈值,则说明温度已经过高,需要立即采取某种快捷、果断的措施,那么则可以直接断开为电子雾化信息生成子装置20提供供电的供电电源。通过直接断电的方式,直接断开电子雾化信息生成子装置20产生热电势的“源头”,以除后患,避免对用户本身造成伤害。
在一个具体的实施例中,例如第一预设温度阈值为25摄氏度,第二预设温度阈值为30摄氏度。具体的第一预设温度阈值和第二预设温度阈值等的相应数值,需要根据实际情况设定,这里仅仅是举例说明,不做实际情况的参考。
可选地,参见图2所示,电子雾化信息控制子装置10,包括:供电模块101、处理模块102和信号采集模块103。
其中,信号采集模块103的一端与电子雾化信息生成子装置20的正极端电连接,另一端与电子雾化信息生成子装置20的负极端电连接,构成第一回路。
供电模块101的一端与电子雾化信息生成子装置20的正极端电连接,另一端与电子雾化信息生成子装置20的负极端电连接,构成第二回路。
供电模块101,用于通过第二回路为电子雾化信息生成子装置20供电;
其中,电子雾化信息生成子装置20的正极端与负极端两端的导线使用不同的导线材料,进而可以保证在供电模块101通过第二回路为电子雾化信息生成子装置20供电后,产生热电势。
信号采集模块103,用于通过第一回路周期性采集电子雾化信息生成子装置20生成的热电势。
信号采集模块103,具体是在脉冲波形处于低电平状态时,采集电子雾化信息生成子装置20生成的热电势。
处理模块102,用于当根据热电势确定电子雾化信息生成子装置20的温度高于第一预设温度阈值时,生成温度控制策略。根据温度控制策略,调控电子雾化信息生成子装置20的温度至第一预设温度阈值以下。
可选地,参见图3所示,考虑到电子雾化信息生成子装置20的两端所产生的热电势可能数据比较小,在建立温度与热电势之间的映射关系时,不同温度对应的热电势会比较接近,容易出现错误。
因此,该电子雾化信息控制子装置10,还可以包括:信号放大模块104;
信号放大模块104,用于对热电势进行放大,获取经过放大后的热电势,以便后续处理模块102根据经过放大后的热电势确定电子雾化信息生成子装置20的温度是否高于第一预设温度阈值。
可选地,参见图5所示,电子雾化信息生成子装置20至少包括电热元件201(也即是背景技术中所提及的雾化元件);当然也包括其他结构,但是其他结构属于现有技术,且不属于本申请侧重研究的重点,因此这里将不再过多介绍。
电热元件201的正极端设置有第一导线202,电热元件201的负极端设置有第二导线203,第一导线202和第二导线203,即为上文中所提及的电子雾化信息生成子装置20的正极端与负极端两端的导线,第一导线202和第二导线203采用不同的材料制成,因此可以在获取到电量后,生成热电势。
电热元件201通过第一导线202,与第三导线204电连接,以及,通过第二导线203,与第四导线205电连接,用以建立信号采集模块103和电热元件201之间的第一回路;
电热元件201通过第一导线202,与第五导线206电连接,以及,通过第二导线203,与第六导线207电连接,用以建立供电模块101和电热元件201之间的第二回路;其中,第三导线204为信号采集模块103的一端电连接的导线,第四导线205为信号采集模块103的另一端电连接的导线。第五导线206为供电模块101的一端电连接的导线,第六导线207为供电模块101的另一端电连接的导线。
考虑到现有技术中的导线材料通常以铁、铜和康铜等材质构成。这些材料不适合作为引线。其中原因就在于电阻较高,功率损失大,发热量大;耐腐蚀性差。而当电子雾化信息生成子装置20中存储有具有较强腐蚀性的雾化液体时,很容易对引线造成腐蚀,甚至还使得引线产生重金属离子,一旦用户通过
口鼻等部位接触电子雾化装置时,很容易吸入重金属离子,对人体造成不可避免的损害。
因此为了保证第一导线202(引线)和第二导线203(引线)可以达到上述要求,则需要在选择第一导线202和第二导线203的构成材料时,满足第一预设条件。
类似的道理,第三导线204、第四导线205、第五导线206,以及第六导线207,主要是在电子雾化信息控制子装置10一侧,用以与电子雾化信息生成子装置20建立电连接,其同样需要满足一定的约束条件。即,第一导线202和第二导线203均需要满足第一约束条件,第三导线204、第四导线205、第五导线206,以及第六导线207均需要满足第二约束条件。
在一个可选的实施例中,第一约束条件包括:
信号采集模块103通过第一导线202和第二导线203,识别热电势信号的精度是否符合预设精度条件;
信号采集模块103通过第一导线202和第二导线203,识别热电势信号的稳定性是否符合预设稳定性条件。
在一个具体的实施例中,为了有效地识别热电势信号,在选择第一导线202和第二导线203的材料时,选择与主流的K型热电偶为同一级别的材料,热电势大约≥10μV/℃;
再者,需要保证材料随着温度变化时,热电势变化趋势成线性及近线性关系,且重复性好。
可选地,第二约束条件包括:
第三导线204至第六导线207的构成材料,承受高温能力大于或者等于第一预设温度阈值;
第三导线204至第六导线207的构成材料,承受预设物质的腐蚀能力大于或者等于预设等级;
第三导线204至第六导线207的构成材料,具有预设等级的可塑性;
第三导线204至第六导线207的构成材料,电阻率小于预设电阻率阈值。
在一个具体的实施例中,例如第三导线204至第六导线207满足如下要求:
1.耐温较高,建议800℃以上;
2.耐电子烟的烟油的腐蚀,且无明显的金属离子析出;
3.容易加工及塑性成型;
4.电阻率与现有镍引线处同一数量级。
结合以上要求,找到了W、Mo、Ag、Pt、Cu、Cr、Ni等金属丝来作为第一导线202至第六导线207的构成材料,一是最大限度的保持了原来的生产及组装工艺的稳定及变化,二是又可以充分满足热电势及引线的性能要求,经过计算及验证,其W-Ni、Cr-Ni、Mo-Ni、Ag-Ni、Pt-Ni等之间不同热电势材料之间的配对产生的热电势曲线与K电偶(NiCr-NiSi)的曲线类似,有利于在电子烟上进行相关的测温(转换电信号为实际温度)。因此,上述可以构成热电势对的导线对可以分别作为第一导线和第二导线。而单独的金属丝则可以统一用于作为三导线至第六导线。例如,第三导线至第六导线均采用Ni。当然,这里仅仅是举例说明,其他可适用于本申请方案,能够符合上述约束条件,且能够构成热电势对的导线材料,以及作为普通导线的导线材料同样属于本申请保护的范围内。
通过热电势材料作为引线,实现电子雾化装置上精确的测温及控制,且还能够保证雾化元件的生成相较于现有技术而言,不增加额外的工序和成本。
在一个具体的实施例中,如下表所示,表1提供了常见材料的电阻率及电极电位,以供对比。

各部件及工作原理已经在上文中做了详细解释说明,因此这里不再赘述。

本申请实施例提供的一种电子雾化装置的温控方法,在电子雾化信息控制子装置为电子雾化信息生成子装置供电后,在电子雾化信息生成子装置的两端产生热电势。电子雾化信息控制子装置可以周期性采集电子雾化信息生成子装置生成的热电势;并且在根据热电势确定电子雾化信息生成子装置的温度高于
第一预设温度阈值时,生成温度控制策略,并根据温度控制策略,调控电子雾化信息生成子装置的温度至第一预设温度阈值以下。通过该方式,可以避免电子雾化信息生成子装置(包括雾化元件和发热体)的温度过高,对用户的人身安全造成危害的情况发生。正因为本申请方案中对电子雾化信息生成子装置的温度进行监控,将其控制在一个范围内(低于第一预设温度阈值),因此可以避免发热体的寿命缩短,也可以避免发热体因为高温产生有害成分而对人体造成伤害。再者,本申请中直接根据热电势来确定温度情况,使得反馈精度和反馈速度相较于现有技术,都有一定的提高,可以克服现有技术中测量温度的精度低以及反馈速度慢等缺陷。
需要说明的是,在本文中,诸如“第一”和“第二”等之类的关系术语仅仅用来将一个实体或者操作与另一个实体或操作区分开来,而不一定要求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序。而且,术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含,从而使得包括一系列要素的过程、方法、物品或者设备不仅包括那些要素,而且还包括没有明确列出的其他要素,或者是还包括为这种过程、方法、物品或者设备所固有的要素。在没有更多限制的情况下,由语句“包括一个……”限定的要素,并不排除在包括要素的过程、方法、物品或者设备中还存在另外的相同要素。
以上仅是本申请的示例性实施例,使本领域技术人员能够理解或实现本申请。对这些实施例的多种修改对本领域的技术人员来说将是显而易见的,本文中所定义的一般原理可以在不脱离本申请的精神或范围的情况下,在其它实施例中实现。因此,本申请将不会被限制于本文所示的这些实施例,而是要符合与本文所申请的原理和新颖特点相一致的最宽的范围。
