Description

发热组件及雾化器 技术领域

 背景技术
雾化芯是雾化器中重要的部件，通常，油液是在加热的雾化芯表面受热而雾化的。
目前的发热组件一般采用方形或圆柱形两种结构形式，对于圆柱形结构的雾化芯，其发热体设置于雾化内的内周壁的雾化面上，该种结构，不利于发热体的设置，并且在外形尺寸一定且需要满足其结构强度的情况下，其雾化面积无法做大；而对于方形结构的雾化芯，发热体和吸液面通常设置在相对的表面上，其余表面需要用于与雾化器的其他结构接触配以固定，或形成过气间隙，其雾化面积也无法做大。因此，不管是现有柱状还是方形雾化形均因尺寸结构受限，存在雾化面积小，导致雾化量小的问题。
 技术问题
本申请实施例的目的之一在于：提供一种发热组件及雾化器，旨在解决雾化芯的雾化量小的问题。

 本发明的实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本申请，并不用于限定本申请。
需说明的是，当部件被称为“固定于”或“设置于”另一个部件，它可以直接在另一个部件上或者间接在该另一个部件上。当一个部件被称为是“连接于”另一个部件，它可以是直接或者间接连接至该另一个部件上。术语“上”、“下”、“左”、“右”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制，对于本领域的普通技术人员而言，可以根据具体情况理解上述术语的具体含义。术语“第一”、“第二”仅用于便于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明技术特征的数量。“多个”的含义是两个或两个以上，除非另有明确具体的限定。
目前，雾化芯多为圆柱状结构，用于与雾化器内的且呈圆管状的通气管相适配。同时，在雾化芯的中部开设有雾化通道，该雾化通道沿圆柱状结构的雾化芯的轴向方向延伸，发热体安装在雾化通道内。考虑到圆柱状结构的雾化芯的结构强度，雾化通道的内径不能过大，从而导致发热体与雾化通道的内壁相接触的面积受限，进而影响单位时间内所形成的雾化气体的烟雾量。
由此，本申请提供一种发热组件100，在发热组件100的周侧壁上进行开设凹槽结构，利用凹槽结构的槽壁与通气管的内壁围合形成雾化通道，进而可增加单位时间内雾化气体的通气量。
请参考图1和图2，本申请实施例提供的发热组件100，包括雾化载体10以及发热体20。其中，雾化载体10用于供烟液、用于医疗用途的药液等雾化液附着，发热体20则是在外设供电电源的作用进行发热，以对附着于雾化载体10的表面上的雾化液进行加热雾化。
雾化载体10具有第一端面10a、与第一端面10a相对设置的第二端面10b，以及第一周侧壁10c、与第一周侧壁10c相对的第二周侧壁10d以及连接第一周侧壁10c和第二周侧壁10d的两个第三周侧壁10e，相对两个第三周侧壁10e上均开设有贯穿第一端面10a和第二端面10b的雾化槽10f，两个雾化槽10f的同一侧向第二周侧壁10d延伸且与外部相连通，雾化槽10f用于供雾化气体通过。可以理解地，雾化载体10是装配于雾化器的通气结构内，通常，雾化载体10呈立方体结构，在使用状态下，雾化载体10的第一端面10a和第二端面10b是与雾化气体的流通方向相垂直的端面，各周侧壁则是与雾化气体的流通方向相平行的侧面。并且，在装配于雾化器的通气结构内时，雾化载体10的第一周侧壁10c和第二周侧壁10d用于抵接于通气结构的雾化腔的内壁，以使雾化载体10能够固定在雾化腔内。以及，两个雾化槽10f位于相对设置的第三周侧壁10e上，并且，两个雾化槽10f的同一侧向第二周侧壁10d延伸且与外部相连通，这样，在平行于第一端面10a或第二端面10b的平面内，雾化槽10f具有背离第三周侧壁10e向外的第一开口以及背离第二周侧壁10d向外的第二开口，该雾化槽10f具有朝向第一周侧壁10c的侧壁和朝向第三周侧壁10e的底壁。通过控制两个雾化槽10f的底壁之间的距离，以及，两个侧壁与第一周侧壁10c之间距离可控制雾化通道的气流流量。例如，两个雾化槽10f的底壁之间的距离越小和两个侧壁与第一周侧壁10c之间距离越小时，雾化通道在平行于第一端面10a或第二端面10b的平面内的截面面积则越大，其单位时间内通过的气流流量也越大。
通常，雾化载体10呈立方体结构，能够与之相适配的雾化器进行装配，当然，依照实际的使用情况，雾化载体10的形状结构不做限定，以能够与雾化器相适配安装为准。
示例地，雾化载体10呈柱状结构，并且，该柱状结构在径向方向的截面形状为圆形、椭圆形、方形等。当然，根据雾化器的通气结构的内部构造的设计情况，该柱状结构在径向方向的截面形状还可为不规则的多边形结构，例如，星形等。
两个雾化槽10f的槽形状可以相同，也可以不同，并且，槽形状的大小也可以相同，也可以不相同。根据实际需求进行调整。
发热体20包括设于其中一个雾化槽10f的槽壁上的第一发热部21以及设于另一雾化槽10f的槽壁上的第二发热部22。这里，第一发热部21和第二发热部22设置在不同的雾化槽10f内，对对应的雾化槽10f的槽壁同步进行加热，使得雾化载体10能够快速升温，达到雾化液所需的雾化温度。
本申请提供的发热组件100，其在雾化器的雾化腔内的安装位置是：第一周侧壁10c抵接于雾化腔的内壁，第二周侧壁10d抵接于雾化腔的相对的内壁上，两个雾化槽10f的槽壁与雾化腔的内壁围合形成雾化通道，发热体20的第一发热部21和第二发热部22分别在对应的雾化通道内进行工作产热，从而对整个雾化载体10进行加热，相较于传统的雾化芯在其中部的开设雾化通道，本申请的发热组件100的雾化通道在平行于第一端面10a或第二端面10b所在平面的截面面积更大，即单位时间内能够通过更多的雾化气体，另外，发热组件100整体呈T形结构，结构简单，发热体20安装方便，由于雾化槽10f的直接贯穿至雾化载体10的侧壁，发热体20整体的大部分通过雾化槽10f可向外显露，方便在生产制造时可以对雾化芯整体进行相关的质量检测等。
在一些实施例中，雾化载体10采用包括但不限于多孔陶瓷、多孔玻璃、棉、纤维或其复合材料制成，发热体20可以采用印刷、涂覆导电浆料形成于雾化载体上，或采用金属材料制成的金属片，包括但不限于网状金属片，其中，金属材料包括金属单单质或合金。作为优选的，雾化载体10采用多孔陶瓷，发热体20为蚀刻金属片，其中，雾化载体10与发热体20可以烧结为一体。
在一个实施例中，第一端面10a、第二端面10b、第一周侧壁10c和第二周侧壁10d的至少一者为用于与雾化液接触的吸液面。可以理解地，当雾化载体10配置于雾化腔内时，第一周侧壁10c和第二周侧壁10d分别与雾化腔的内壁相抵接而实现连接固定，因此，油液可通过第一周侧壁10c和/或第二周侧壁10d进入雾化载体10，即第一周侧壁10c和/或第二周侧壁10d作为吸液面。或者，第一端面10a和第二端面10b均与雾化气体雾化升腾的方式相垂直，也作为与雾化液接触的吸液面。或者，第一端面10a、第一周侧壁10c和第二周侧壁10d均作为与雾化液接触的吸液面。或者，第二端面10b、第一周侧壁10c和第二周侧壁10d均作为与雾化液接触的吸液面。或者，第一端面10a、第二端面10b、第一周侧壁10c和第二周侧壁10d均作为与雾化液接触的吸液面。
请参考图3、图4和图7，发热体20还包括第三发热部23，第三发热部23的至少部分设置于至少一个吸液面上。可以理解地，第三发热部23的至少部分是指第三发热部23与吸液面存在干涉，并且，根据实际使用需求，可选择第三发热部23与吸液面的干涉程度。同时，第三发热部23可选择地设置第一端面10a、第二端面10b、第一周侧壁10c和第二周侧壁10d的至少一者上。
示例地，如图5所示，第三发热部23平铺在第二周侧壁10d上，与第一发热部21和第三发热相邻设置，这样，三个发热部更有容易实现电性连接，并且，雾化载体10的三个周侧壁同步被加热，雾化载体10升温更快。
在一个实施例中，第一发热部21、第二发热部22和第三发热部23之间可采用串联或并联的方式进行电性连接。因此，第三发热部23连接于第一发热部21和第二发热部22的至少一者即可。
示例地，第三发热部23的相对两端连接于第一发热部21或第二发热部22上，此时，第三发热部23则与第一发热部21或第二发热部22进行并联连接。
或者，示例地，第三发热部23的相对两端分别连接于第一发热部21和第二发热部22上，此时，第三发热部23则与第一发热部21和第二发热部22进行串联连接。
具体地，请参考图5，在一个实施例中，第三发热部23的两端分别连接于第一发热部21和第二发热部22。此时，第三发热部23则与第一发热部21和第二发热部22进行串联连接，三个发热部的电流相同，通过调整各发热部的电阻，以调整各发热部的发热功率。
在一个实施例中，第一发热部21和第二发热部22的至少一者的发热功率大于第三发热部23的发热功率。可以理解地，第一发热部21的发热功率大于第三发热部23的发热功率；或者，第二发热部22的发热功率大于第三发热部23的发热功率；或者，第一发热部21的发热功率和第二发热部22的发热功率均大于第三发热部23的发热功率。同时，由于第三发热部23的发热功率与其他两个发热部的发热功率存在差异，那么，雾化槽10f的槽壁与吸液面的升温速率则不同，尤其吸液面作为与油液等雾化液先接触的侧面时，吸液面上的油液可在第三发热部23的热作用下提高流动性，使其保持良好的传输性从而可快速地附着于整个雾化载体10的表面，避免干烧的现象发生。
在本实施例中，第一发热部21的发热功率不同于和第二发热部22的发热功率，也即第一发热部21和第二发热部22在工作时，具有不同的发热温度，如此，当发热组件100整体在对雾化液进行加热雾化时，通过第一发热部21和第二发热部22不同发热温度，可以将不同挥发温度的组分雾化出来，以提高加热雾化形成的气溶胶的口感，提高用户的吸食体验。
在发热材质相同的情况下，第三发热部23的厚度、宽度、发热区走线形态的可区别于其他两个发热部，可最终导致二者的电阻值不同，进而导致第三发热部23的发热功率较低。
在发热部形状结构的情况下，第三发热部23的材质的米阻更低，进而导致第三发热部23的电阻值最小。
具体地，在一个实施例中，第一发热部21和第二发热部22至少一者的发热面积大于第三发热部23的发热面积。可以理解地，第一发热部21的发热面积大于第三发热部23的发热面积；或者，第二发热部22的发热面积大于第三发热部23的发热面积；或者，第一发热部21和第二发热部22的发热面积大于第三发热部23的发热面积。同时，在本实施例中，三个发热部的材质相同，通过调整发热面积来实现发热功率的改变。
请参考图5、图7和图8，在一些实施例中，第三发热部23为菱形结构或波浪型结构，但不限于此。作为示例的，第三发热部23包括至少两个串联的菱形结构，或者，第三发热部23呈波浪型结构。由于第三发热部23在雾化载体10上的设置位置可以为非雾化区，在第三发热部23通电发热时可以起到预热雾化介质的作用，以降低雾化液的粘性，提高雾化液在雾化载体10内的流动性，降低在第一发热部21或第二发热部22对雾化液进行加热雾化时，因雾化液粘稠性大，流动性低，导致无法及时流动至第一发热部21和/或第二发热部22等位置，造成雾化液在发热体20存在局部缺失，从而出现干烧糊味等现象。
其中，第三发热部23可以与第二周侧壁10d的表面齐平设置，以提高第三发热部23与雾化载体10的接触面积及结合强度，同时保证发热组件100整体外观的一致形，避免第三发热部23凸出于第二周侧壁10d外而造成发热组件100的表面凹凸不平，更有利于发热组件100后续的装配。
本实施例中，第三发热部23连接于第一发热部21和第二发热部22之间，使得发热体20整体呈U形或者呈大致的U形，以便于发热体20可以通过该U形结构夹持固定于雾化载体10上，提高二者连接的稳定性和可靠性，另外，发热体20也可以通过上述U形结构可拆卸地套设于雾化载体10上，方便拆装。进一步的，发热体20可以由位于同一平面上的第一发热部21、第二发热部22和第三发热部23通过弯折而形成U形结构，如此，在加工制造时，可以采用蚀刻成型的加工工艺先将批量生产整体呈平面结构的发热体20，然后再进行弯曲成型，有利于实现自动化批量生产，降低生产成本。
请参考图7、图10和图11，在一个实施例中，第一发热部21和第二发热部22中的至少一者的相对两端弯折且嵌入雾化载体10内。可以理解地，第一发热部21的相对两端是指第一发热部21靠近第三发热部23的一端和背离第三发热部23的一端。如此，第一发热部21的相对两端在弯折后嵌入雾化载体10内，以增加与雾化载体10的连接位，提高二者的连接稳定性。同时，也增加了第一发热部21与雾化载体10的接触面积，可以将热量较快速地传递至雾化载体10。同理地，第二发热部22的相对两端是指第二发热部22靠近第三发热部23的一端和背离第三发热部23的一端。同样地，能够实现上述的效果。
或者，在另一个实施例中，第一发热部21和第二发热部22中的至少一者远离第三发热部23的一端嵌入雾化载体10内。可以理解地，在第一发热部21和/或第二发热部22的端侧朝向背离第三发热部23的方向延伸，并且雾化载体10形成连接关系。
请参考图7，具体地，第一发热部21和第二发热部22在各自两端之间还设有导热引脚20a。这里，导热引脚20a与发热部20的主体的材质相同，仅是形状结构上不同。即，导热引脚20a可呈平直的状态，嵌入雾化载体10内；也可呈弯折的状态，嵌入雾化载体10内。
请参考图10和图11，导热引脚20a向第一周侧壁的方向延伸并嵌入雾化载体10内。可以理解地，第一发热部21和/或第二发热部22上的导热引脚20a可朝向雾化载体10的第一方向延伸，并嵌入雾化载体10内进行连接。
请参考图6，在一个实施例中，吸液面上设有聚液结构10g，聚液结构10g用于吸附油液在吸液面上。可以理解地，根据选择雾化载体10不同的端面和/或周侧壁作为吸液面，那么，聚液结构10g可设置上述任意一个或几个上。
聚液结构10g可增加吸液面与油液的接触面积。例如，聚液结构10g为形成吸液面上的凸部或凹部，或者凸部和凹部，相较于吸液面用于与进液孔相对的吸液平面，在吸液面上形成多个凸部或凹部进一步地增加吸液面积，即，能够聚集油液的总量更多。这里，凸部不仅限于凸齿、凸筋等结构，以及，凹部不仅限于凹坑、凹槽等。
具体地，请参考图9和图10，在一个实施例中，聚液结构10g包括开设于吸液面上的储液凹部10g1。可以理解地，储液凹部10g1可以是呈阵列分布的槽结构，因此，呈阵列分布的形式不做限定；或者，储液凹部10g1可以是多个凹坑。例如，储液凹部10g1可在沿吸液面的宽度或长度方向上间隔设置；或者，储液凹部10g1在沿吸液面的宽度和长度方向上间隔设置；或者，储液凹部10g1在沿与吸液面的宽度或长度方向呈夹角的方向上间隔设置；或者，储液凹部10g1以吸液面的中心为圆心，且相间隔地呈同心圆设置等。同时，储液凹部10g1的槽结构的形状结构也不做限制。例如，储液凹部10g1的槽结构的截面形成可呈方形、三角形、梯形或者圆弧形等。以及，储液凹部10g1的槽结构还可为沿吸液面的宽度或长度贯通该吸液面的槽结构，也可为非贯通的槽结构等。
这里，储液凹部10g1能够增加吸液面的吸液面积，同时可对雾化载体10在装配时达到限位的目的。在雾化载体10装配于雾化器内时，雾化载体10的吸液面通常采用棉、无纺布等柔性导液件安装在雾化器的通气管内的开孔位置，这样，雾化介质通过柔性导液件后附着在吸液面的储液凹部10g1处，既可以增加与柔性导液件的接触配合面积，以及与通气管之间连接位，避免雾化载体10在通气管内发生移动。
请参考图9和图10，在其他实施例中，聚液结构10g包括开设于吸液面上的储液室10g2。可以理解地，储液室10g2的形状结构、在吸液面上的设置位置以及数量不做限定，以能够存储油液为主。同时，储液室10g2可为盲孔，即，在贯通聚液结构10g后与吸液面相连通，即，此时，储液室10g2的孔底面与吸液面的吸液面处于共面状态。或者，储液室10g2还可为通孔，在贯通聚液结构10g后也贯通吸液面，即，储液室10g2延伸至吸液面的内部。在雾化载体10内，由第一发热部21、第二发热部22和第三发热部23之间所围合的区域中，其温度相对较高，属于高温区域，容易因为供油不及时导致干烧等问题，因此，为了降低雾化载体10在该区域的温度，提高雾化液的供给速度和供给量，储液室10g2也可以从吸液面的表面延伸设置雾化载体10内与第一发热部21、第二发热部22以及第三发热部23所围合的区域内。
这里，储液室10g2主要功能是缓存雾化介质，同时，可缩短雾化介质到各发热部的距离，提高供液速率和供液量，发热体的热量可以通过较短的路径及时地传递至位于储物室内的雾化介质，有利于提高雾化量、降低功耗，防止干烧的现象发生。
或者，请参考图9和图10，在一些实施例中，聚液结构10g包括开设于吸液面上的储液室10g2和储液凹部10g1。这里，储液室10g2的空间更大，能够存储更多的雾化介质，以及，较大幅度地缩短雾化介质的传输路径，和发热体的热量传输路径。并且，储液凹部10g1则是增加雾化载体10的吸液面与雾化介质的接触面。综上，在吸液面上同时设置储液室10g2和储液凹部10g1，则同时具有上述两个优点。
请参考图5，在一个实施例中，第一周侧壁10c和第二周侧壁10d均为吸液面，第三发热部23设置于第二周侧壁10d上，聚液结构10g设置于第一周侧壁10c上。可以理解地，雾化液从第一周侧壁10c和第二周侧壁10d进入雾化载体10。第一发热部21和第二发热部22设置在雾化槽10f内，第三发热部23设置于第二周侧壁10d上，这样，三个周侧壁被同步加热，升温速率更快。
本申请中发热组件100整体呈T形结构，通过将聚液结构10g设置在第一周侧壁10c以整体结构尺寸空间有限满足发热组件100整体结构强度的情况下，提高发热组件100的有效吸液面积和储液空间，避免因发热组件100在工作时，因供液不及时出现干烧糊味等问题。
本申请实施例还提供一种雾化器，包括上述的发热组件100。
本申请提供的雾化器，在具有上述发热组件100的基础上，该雾化器在单位时间内产生的雾化气体总量更多。
