Description
本申请要求于2021年06月04日提交中国专利局、申请号为202121248153.X、发明名称为“用于雾化液体的发热体及雾化器”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
本申请涉及液体雾化领域，尤其涉及一种用于雾化液体的发热体及雾化器。
在雾化器领域，通过发热片通电发热，使得该发热片接触到的液体雾化，雾化的液体随抽吸气流被带出该雾化器。在现有技术中，抽吸气流随使用者的抽吸动作，由安装座的底部进入安装座，并通过发热体和导油体的两侧流出安装座，进入顶部组件和一次性储油部件，并最终溢出雾化器。这种方式虽然也能够实现雾化液体的扩散。但是，其缺陷也是明显的，气溶胶在随抽吸气流分开到发热体和导油体的两侧时，不可避免地会与发热体碰撞，然后分开进入两侧。这些碰撞会使得雾化的液体中的一部分出现冷凝的情况，重新变回液体，这种情况不仅使得安装座的底面可能出现渗液的情况，也会使得同等条件下雾化器的出雾量较小。
申请内容

在一种具体实施例中，下面通过具体的实施例并结合附图对本申请做进一步的详细描述。
如图1和图2所示，在本发明的用于雾化液体的发热体及雾化器实施例中，构造一种用于雾化液体的发热体，所述发热体包括发热片1和支撑体2，所述支撑体2对所述发热片1做刚性支撑，以防止所述发热片1在外力(通常是在装配构成中产生的装配应力或装配完成后其他部件对发热片1的作用力)的作用下变形。本实施例中，发热片1设置在支撑体2的上方；但是，可以理解地，发热片1也可以设置支撑体2的内部，例如镶嵌或者焊接在支撑体2内部，如此也能使支撑体2刚性支撑发热片1。发热片1包括发热部11和分别连接到发热部11两端的两个固定部12。发热部11上设置有气流通道。
所述支撑体2还设置有贯穿其顶面和底面的、便于抽吸气流通过的镂空部21；所述发热片1的发热部11的气流通道与所述镂空部21重叠，可以是全部重叠或部分重叠。也就是说，在本实施例中，由于在支撑体2设置有镂空部21，且镂空部21的位置和放置在支撑体2上的发热体1的气流通道重叠或直接连 通，于是，处于雾化空间31(请参见图3，雾化空间31位于支撑体2的下方)中的气溶胶，在抽吸气流的作用下，能够直接穿过上述镂空部21和气流通道，流动到上述发热体的上方，而不需要像现有技术中一样碰撞到支撑体2的底面再转向其两侧向上传输。因此，采用这种结构时，位于雾化空间31中的气溶胶的碰撞较小，重新冷凝为液体的可能较小，基本上不会出现渗液的情况，产生的气溶胶基本都随抽吸气流流出，于是雾化效率较高。
在本实施例中，所述发热部的设置是便于气流通过，因此能够使得气流直接通过的结构都可以使用，例如，上述发热部的形状或结构可以是如图1所示的网状结构，也可以是条状结构或镂空结构(图中未示出)。上述条状结构可以由多条相互隔开的、其间设置有设定宽度缝隙的直的或者波浪状的条状物构成；而镂空结构则是直接在发热部的相应位置挖出设定形状的通孔，贯穿上述发热部的顶面和底面。发热部11的主要目的是有足够的工作电阻值以便于发热，以及具有气流通道以便于气溶胶和空气流过。
在本实施例中，就图1示出的网状结构而言，虽然上述发热部11也能够使得气溶胶和空气通过，但是相对来讲，发热部11本身对气溶胶还是存在一些阻碍的。为了进一步改善气溶胶通过发热片1的状态，如图1所示，在所述发热部11的中央还设置有大于所述网状结构通孔的第一通孔14，所述第一通孔14位于所述镂空部21的上方。这样，通过镂空部21的气溶胶就能够直接通过上述第一通孔14而进入到发热片1的上方，这就减少了发热部11的网线(包围网孔并形成网孔边沿的部分)对于气溶胶的阻挡，进一步提高了气溶胶通过上述发热片1的效率。
在本实施例中，所述支撑体2由致密性陶瓷基体构成，致密性陶瓷基体的特性使得支撑体2除了上述镂空部21外，其余部分并不会透气或透油。而所述发热片1通过烧结、焊接或粘接连接在所述支撑体1的表面。例如，可以将发热片1嵌入或放置在未烧结的陶瓷基体表面，然后烧结，使二者结合在一起；也可以在已经成型的支撑体2上使用胶黏剂，将发热片1粘接在支撑体2上。不 管采用那种方式将上述发热片1和支撑体2结合在一起，上述镂空部21和发热部11或第一通孔14的位置都需要对齐。一般来讲，上述镂空部21位于上述支撑体2中央，而第一通孔14则位于上述镂空部21的中央。为了实现气溶胶随抽吸气流的流动，上述镂空部21和第一通孔14还与上述雾化空间31和构成气流通道的其他部件的结构(例如，顶部组件的气流通道结构)对准。
如图1和图2所示，在本实施例中，上述支撑体2和发热片1均具有长条形的外形，即支撑体2和发热片1均具有较长的长度和较小的宽度，在将上述发热片1放置到上述支撑体2上时，二者的长度方向是一致的。由于发热体1的结构是发热部11处于其长度方向的中间位置，所述，在上述支撑体2中，其镂空部21也处于该支撑体2的长度方向的中心位置，也就是说，所述镂空部21沿所述支撑体2的长度方向设置，且处于其中间位置；所述镂空部21的宽度小于所述支撑体2的宽度，也就是说，上述镂空部21的宽度方向上具有两个边沿，该边沿作为支撑体2的一部分存在。
在本实施例中，由图1和图2可以清楚地看到，所述发热部11的宽度大于所述支撑体2对应部分的宽度，当上述发热片1放置到上述支撑体2上时，所述发热部11的边沿向下折弯以夹持或嵌入所述支撑体2的侧面。这样设置的好处，一方面可以使得上述发热片1和支撑体2之间的位置关系确定，使得在加工或装配过程中，上述发热片1不会移动，从而使得上述发热部11或第一通孔14与上述镂空部21对准，便于气溶胶的流动；另外一方面，也使得上述发热片1在支撑体2上能够得到多个方向的支撑，进一步加强二者之间的连接，使得二者之间的连接更加稳固。
在本实施例中，所述发热部11的宽度方向上的两端向下折弯包围住上述支撑体2的侧面。所述两个固定部12上分别设置有固定孔13，所述支撑体2的对应位置上设置有第二通孔22(请参见图2)，在本实施例中，上述发热片1和电源之间的连接是通过电极实现的，电极穿过安装座3(请参见图3)的底面和顶面，进入上述第二通孔22，与上述发热片1的底面相接触，但是，这样 的接触并不可靠，于是，使用固定螺钉通过所述电极安装孔13和所述第二通孔22并与位于所述发热片1下方的电极连接，当上述固定螺钉牢固连接在上述电极末端(与发热片1接触的一端)上时，就实现所述发热片1的固定部12与电极的连接，从而实现了通过电极连接电源和发热片1的功能。或者是通过焊接或者铆接的方式将电极与发热片的固定部电连接。
在本实施例中，所述网状结构通过选择不同的网格大小、网格形状、围合所述网格的网线的宽度和形状，使得发热部11的工作电阻值在设定的范围内。一般来讲，上述发热片1的电阻值的设定范围在0.5-2欧姆之间，优选的电阻值为1.1欧姆。值得一提的是，这样的设置当然是是事先设定的，当上述发热片被加工出来后，其电阻值也就确定了。
图3示出了在本实施例中上述发热体装配在整个雾化器中的具体情况，在图3中，在安装座3上放置上述发热体，发热体上在依次放置导油体4和顶部组件5，其中导油体4上设置有导油体气流通道41，顶部组件5上设置有顶部组件气流通道51，而安装座3上设置有雾化空间31，该雾化空间31用于容纳通过上述发热体加热而形成的气溶胶。在抽吸动作出现后，外部空气首先沿上述安装座3的底面进入安装座，然后通过安装座3两侧的气流通道32进入上述雾化空间31，在这一步骤中，外部气流是通过两侧进气汇流于上述雾化空间31中；进入上述雾化空间31后，该气流依次通过上述镂空部21、第一通孔14、导油体气流通道41和顶部组件气流通道51，然后进入一次性储油部件(图中未示出)的气流通道(图中未示出)，随抽吸动作流出该雾化器，实现了液体的雾化及输出。在图3中，由上述雾化空间31开始，气流或气溶胶的传输途径就是直线，图3中用虚线箭头指出了该气流的传输途径，并不存在方向的转折，因此，在本实施例中，上述携带了气溶胶的抽吸气流的传输途径较为直接，气溶胶的碰撞及转向的可能性基本不存在，这就使得气溶胶在传输途径中基本不会出现由于碰撞而出现的冷凝情况，所以不会因为冷凝导致气溶胶变回液体的情况，自然也就不存在因为冷凝而出现渗液的情况。
本发明还涉及一种雾化器，包括用于将液体雾化的发热体，所述发热体包括上述的用于雾化液体的发热体。
以上所述仅为本申请的优选实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
