Description

发热体和气溶胶产生装置
本申请要求于2021年12月31日提交到中国国家知识产权局、申请号为“202111678042.7”、申请名称为“发热体和气溶胶产生装置”的中国专利申请的优先权，于2021年12月31日提交到中国国家知识产权局、申请号为“202123425671.7”、申请名称为“发热体和气溶胶产生装置”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。
技术领域
本申请的实施例涉及电子雾化技术领域，具体而言，涉及一种发热体和一种气溶胶产生装置。
背景技术
目前，雾化器用中心管式棉芯发热体是一种新形式的雾化发热体，它相较于传统的棉绳式发热体和包棉式发热体，具有更高的雾化量。
中心管式棉芯发热体的基本结构由三部分组成：中心支撑管、管套状棉层和电阻丝。管套状棉层连接中心支撑管中的气溶胶生成基质与电阻丝，气溶胶生成基质在管套状棉层表面被电阻丝加热雾化。而管套状棉层的形态、密度、表面、材质对雾化过程和产生的气溶胶有重要影响，其差异会直接导致雾化器成品的口感变化。
管套状棉层有两种形式，一是布片包裹式棉层，二是环形海绵式棉层。其中，布片包裹式棉层在其雾化区域存在布片端头，端头处的棉层形状不规则，与其余区域的形态存在明显区别，造成雾化状态不可控。
环形海绵式棉层由于海绵的可压缩性大，被发热丝缠绕的部分棉层被严重压缩，与无发热丝缠绕的部分厚度差异较大，导致棉层的一致性差。
发明内容
本申请的实施例旨在至少解决现有技术中存在的技术问题之一。
为此，本申请的实施例的第一方面提供了一种发热体。
本申请的实施例的第二方面提供了一种气溶胶产生装置。
有鉴于此，根据本申请的实施例的第一方面，提供了一种发热体，发热体用于加热雾化气溶胶产生基质，发热体包括：支撑管；导通层，设于支撑管的外侧，并与支撑管相连通，导通层为整体编织结构。
本申请实施例提供的发热体包括支撑管和导通层，具体而言，导通层设置在支撑管的外侧，且导通层与支撑管相连通，能够理解的是，支撑管内通入气溶胶产生基质，由于导通层与支撑管相连通，从而使得气溶胶产生基质能够流向导通层，发热体的发热丝对流向导通层的气溶胶产生基质进行加热雾化，产生气溶胶。其中，气溶胶产生基质可为固体气溶胶产生基质或液态气溶胶产生基质。
进一步地，导通层为整体编织结构，也就是说，导通层由导通基质采用编织的方法制成编织结构，从而使得导通层具有很好的完整性和一致性。相较于相关技术中将导通层采用布片包裹式棉层而言，能够确保导通层各个位置形态的一致性，进而确保具有该发热体的气溶胶产生装置的雾化状态可控。而且，相较于相关技术中将导通层采用环形海绵式棉层而言，采用编织法形成的导通层，可压缩性较小，从而使得导通层被发热丝缠绕部分与无发热丝缠绕部分的厚度差异较小，进而使得导通层具有很好的一致性，确保气溶胶产生装置的口感。
此外，将导通层设置为整体编织结构，即在支撑管的外侧采用编织的方法形成导通层，还能够使导通层与支撑管之间紧密贴合，从而确保导通层与支撑管之间的缝隙可控，便于密封，且还可以防止漏液。
在实际应用中，可利用编织机将纱线编织形成导通层，即导通层为棉层，也即发热体为棉芯发热体，从而能够在确保棉层具有很好的完整性和一致性的同时，使得气溶胶产生装置具有更高的雾化量。
值得说明的是，发热体还包括发热丝，发热丝螺旋缠绕于导通层的外侧，在利用编织机将导通层包裹在支撑管外后，可以利用绕线机将发热丝缠绕在导通层的外侧，从而能够进一步确保导通层各个位置的一致性。具体地，相关技术中在绕设发热丝时，均采用手动安装，从而导致发热丝和导通层的组装一致性差，且组装效率低。通过绕线机将发热丝绕设于导通 层的外侧，能够有效克服由于手动安装发热丝导致的一致性差的问题，提高产品组装效率，使得不同气溶胶产生装置的口感具有很好的一致性。
在具体应用中，整体编织结构的编织纹理可以根据实际需要进行设置。

在一种可能的设计中，导通层的厚度d满足0.1mm≤d≤3mm。
在该设计中，限定了导通层的厚度d满足0.1mm≤d≤3mm。能够理解的是，导通层的厚度不易过厚，若导通层的厚度过厚，不利于气溶胶产生基质的流通。且还使得导通层的可压缩性增加，在绕设发热丝时，易导致导通层各个位置的一致性差。此外，导通层的厚度不易过薄，若导通层的厚度过薄，会影响气溶胶产生装置的雾化量。通过将导通层的厚度限定在0.1mm至3mm之间，能够在使导通层各个位置具有很好的一致性的同时，确保气溶胶产生装置的雾化量。

在该设计中，限定了导通层包括棉线或棉纱，也就是说，将棉线采用编织的方法制备导通层，从而使导通层形成为整体编织结构。即导通层为棉层，也即发热体为棉芯发热体，从而能够在确保棉层具有很好的完整性和一致性的同时，提高气溶胶产生装置的雾化量。
另外，也可以将棉纱采用编织的方法制备导通层，从而使得到导通层形成为整体编织结构。具体可以根据实际需要进行设置。
在实际应用中，可采用编织机将棉线或棉纱编织包裹在支撑管的外侧，能够理解的是，可以通过调整编织机的编织速度来控制导通层的密度和厚度。具体地，编织纹理可以是斜纹、“+”字纹或“人”字纹等，具体可以根据实际需要进行设置。
在一种可能的设计中，棉线或棉纱包括8股至64股纱线。
在该设计中，限定了棉线或棉纱包括8股至64股纱线。也就是说，将8股至64股纱线利用编织机编织形成导通层，从而使导通层形成为整体编织结构。即导通层为棉层，也即发热体为棉芯发热体，从而能够在确保棉层具有很好的完整性和一致性的同时，提高气溶胶产生装置的雾化量。
此外，通过将棉线或棉纱包括8股至64股纱线，能够确保编织形成的导通层具有设定厚度和流通性。
在实际应用中，纱线可以为单股纱线，或2股至8股二级纱线合并形成的，具体可以根据实际需要进行设置。
在一种可能的设计中，纱线为单股一级纱线；或纱线包括2股至8股二级纱线。
在该设计中，限定了纱线可以为单股一级纱线，即由8股至64股一级纱线利用编织机编织形成导通层，从而使导通层形成为整体编织结构。纱线也可以是由2股至8股二级纱线合并形成的，再由8股至64股合并形成的二级纱线利用编织机编织形成导通层，从而使导通层形成为整体编织结构。从而能够在确保棉层具有很好的完整性和一致性的同时，提高气溶胶产生装置的雾化量。
在实际应用中，纱线材料可以是长丝或短丝所制的有捻纱线或无捻纱线，具体可以根据实际需要进行设置。
在一种可能的设计中，纱线的直径D满足0.05mm≤D≤2mm。
在该设计中，限定了纱线的直径D的取值范围。也即限定每股一级纱线或每股合并的二级纱线的直径的取值范围。能够理解的是，若纱线的直径过小，则编织形成的导通层的结构强度较低，降低发热体的使用寿命。若纱线的直径过大，则编织形成的导通层易过厚，不利于气溶胶产生基质的流通，影响气溶胶产生装置的雾化量。通过将纱线的直径限定的0.05mm至2mm之间，能够在确保导通层具有一定结构强度的同时，提高气溶胶产生装置的雾化量。
在一种可能的设计中，纱线的细度S满足10支≤S≤60支。
在该设计中，能够理解的是，纱线的细度越大，纱线直径越细，通过进一步限定纱线的细度的取值范围，能够进一步确保导通层具有一定结构强度的同 时，提高气溶胶产生装置的雾化量。
在一种可能的设计中，发热体还包括发热丝，发热丝绕设于导通层的外侧，发热丝包括多个环绕部，其中，多个环绕部与导通层之间具有间距；或多个环绕部与导通层相接触。

进一步地，发热丝包括多个环绕部，其中，多个环绕部与导通层之间具有间距或者多个环绕部与导通层相接触，也就是说，在将发热丝绕设在导通层外侧时，能够不压缩导通层，从而使得导通层有发热丝缠绕的部分和无发热丝缠绕的部分的厚度一致，进一步确保导通层的一致性，进而确保气溶胶产生装置的雾化状态可控。
在实际应用中，可以利用绕线机将发热丝缠绕在导通层的外侧，从而能够进一步确保导通层各个位置的一致性。具体地，相关技术中在绕设发热丝时，均采用手动安装，从而导致发热丝和导通层的组装一致性差，且组装效率低。通过绕线机将发热丝绕设于导通层的外侧，能够有效克服由于手动安装发热丝导致的一致性差的问题，提高产品组装效率，使得不同气溶胶产生装置的口感具有很好的一致性。
在一种可能的设计中，支撑管包括本体和多个通孔，其中，本体设有导通腔，多个通孔设于本体，多个通孔与导通腔和导通层相连通。
在该设计中，限定了支撑管包括本体和多个通孔，具体而言，本体设有导通腔，能够理解的是，气溶胶产生基质能够通入导通腔内，并经本体上的多个通孔流向导通层，发热体的发热丝对流向导通层的气溶胶产生基质进行加热雾化，产生气溶胶。
在实际应用中，支撑管的材质包括金属材料、陶瓷材料、玻璃或工程塑料中的一种，从而确保支撑管的结构强度，进而能够为导通层提供有效的支撑。

在一种可能的设计中，本体的内径a满足0.3mm≤a≤3mm。
在该设计中，限定了本体内径的取值范围，也即限定了导通腔宽度的取值范围。能够理解的是，本体的内径若过小，即导通腔的宽度过小，则单位体积通入的气溶胶产生基质的量较小，降低气溶胶产生装置的雾化量。若本体的内径过大，则使得发热体的体积较大，一方面会占用气溶胶产生装置的内部空间，另一方面，还会导致气溶胶产生装置的体积较大，不利于产品的美观。通过将本体的内径限定在0.3mm至3mm之间，能够在确保气溶胶产生装置雾化量的同时，提高产品的美观性。

在该设计中，限定了通孔孔径的取值范围，具体地，通孔的孔径n满足0.01mm≤n≤3mm。能够理解的是，通孔的孔径若过小，则不利于气溶胶产生基质的流通，降低气溶胶产生装置的雾化量。通孔的孔径若过大，则降低支撑管的结构强度，进而降低发热体的使用寿命。通过将通孔的孔径限定在0.01mm至3mm之间，能够在确保气溶胶产生装置雾化量的同时，延长发热体的使用寿命。

本申请实施例提供的发热体100包括支撑管110和导通层120，具体而言，导通层120设置在支撑管110的外侧，且导通层120与支撑管110相连通，能够理解的是，支撑管110内通入气溶胶产生基质，由于导通层 120与支撑管110相连通，从而使得气溶胶产生基质能够流向导通层120，发热体100的发热丝130对流向导通层120的气溶胶产生基质进行加热雾化，产生气溶胶。其中，气溶胶产生基质可为固体气溶胶产生基质或液态气溶胶产生基质。

此外，将导通层120设置为整体编织结构，即在支撑管110的外侧采用编织的方法形成导通层120，还能够使导通层120与支撑管110之间紧密贴合，从而确保导通层120与支撑管110之间的缝隙可控，便于密封，且还可以防止漏液。

在该实施例中，限定了导通层120的厚度d满足0.1mm≤d≤3mm。能够理解的是，导通层120的厚度不易过厚，若导通层120的厚度过厚，不利于气溶胶产生基质的流通。且还使得导通层120的可压缩性增加，在绕设发热丝130时，易导致导通层120各个位置的一致性差。此外，导通层120的厚度不易过薄，若导通层120的厚度过薄，会影响气溶胶产生装置的雾化量。通过将导通层120的厚度限定在0.1mm至3mm之间，能够在使导通层120各个位置具有很好的一致性的同时，确保气溶胶产生装置的雾化量。
实施例二：
如图1、图2、图5、图6和图7所示，在上述任一实施例的基础上，进一步地，导通层120包括棉线或棉纱，导通层120由棉线或棉纱采用编织的方法形成整体编织结构。
在该实施例中，限定了导通层120包括棉线或棉纱，也就是说，将棉线采用编织的方法制备导通层120，从而使导通层120形成为整体编织结构。即导通层120为棉层，也即发热体100为棉芯发热体，从而能够在确保棉层具有很好的完整性和一致性的同时，提高气溶胶产生装置的雾化量。
另外，也可以将棉纱采用编织的方法制备导通层120，从而使得到导通层120形成为整体编织结构。具体可以根据实际需要进行设置。
在实际应用中，可采用编织机将棉线或棉纱编织包裹在支撑管110的外侧，能够理解的是，可以通过调整编织机的编织速度来控制导通层120的密度和厚度。具体地，编织纹理可以是斜纹、“+”字纹或“人”字纹等，具体可以根据实际需要进行设置。
在上述实施例的基础上，进一步地，棉线或棉纱包括8股至64股纱线。
在该实施例中，限定了棉线或棉纱包括8股至64股纱线。也就是说，将 8股至64股纱线利用编织机编织形成导通层120，从而使导通层120形成为整体编织结构。即导通层120为棉层，也即发热体100为棉芯发热体，从而能够在确保棉层具有很好的完整性和一致性的同时，提高气溶胶产生装置的雾化量。
此外，通过将棉线或棉纱包括8股至64股纱线，能够确保编织形成的导通层120具有设定厚度和流通性。
在实际应用中，纱线可以为单股纱线，或2股至8股二级纱线合并形成的，具体可以根据实际需要进行设置。
在上述实施例的基础上，进一步地，纱线为单股一级纱线；或纱线包括2股至8股二级纱线。
在该实施例中，限定了纱线可以为单股一级纱线，即由8股至64股一级纱线利用编织机编织形成导通层120，从而使导通层120形成为整体编织结构。纱线也可以是由2股至8股二级纱线合并形成的，再由8股至64股合并形成的二级纱线利用编织机编织形成导通层120，从而使导通层120形成为整体编织结构。从而能够在确保棉层具有很好的完整性和一致性的同时，提高气溶胶产生装置的雾化量。
在实际应用中，纱线材料可以是长丝或短丝所制的有捻纱线或无捻纱线，具体可以根据实际需要进行设置。
在一个具体的实施例中，进一步地，纱线的直径D满足0.05mm≤D≤2mm。
在该实施例中，限定了纱线的直径D的取值范围。也即限定每股一级纱线或每股合并的二级纱线的直径的取值范围。能够理解的是，若纱线的直径过小，则编织形成的导通层120的结构强度较低，降低发热体100的使用寿命。若纱线的直径过大，则编织形成的导通层120易过厚，不利于气溶胶产生基质的流通，影响气溶胶产生装置的雾化量。通过将纱线的直径限定的0.05mm至2mm之间，能够在确保导通层120具有一定结构强度的同时，提高气溶胶产生装置的雾化量。
在另一个具体的实施例中，进一步地，纱线的细度S满足10支≤S≤60支。
在该实施例中，能够理解的是，纱线的细度越大，纱线直径越细，通过进一步限定纱线的细度的取值范围，能够进一步确保导通层120具有一定结构强度的同时，提高气溶胶产生装置的雾化量。
实施例三：
如图1和图3所示，在上述任一实施例的基础上，进一步地，发热体100还包括发热丝130，发热丝130绕设于导通层120的外侧，发热丝130包括多个环绕部，其中，多个环绕部与导通层120之间具有间距；或多个环绕部与导通层120相接触。

进一步地，发热丝130包括多个环绕部，其中，多个环绕部与导通层120之间具有间距或者多个环绕部与导通层120相接触，也就是说，在将发热丝130绕设在导通层120外侧时，能够不压缩导通层120，从而使得导通层120有发热丝130缠绕的部分和无发热丝130缠绕的部分的厚度一致，进一步确保导通层120的一致性，进而确保气溶胶产生装置的雾化状态可控。
在实际应用中，可以利用绕线机将发热丝130缠绕在导通层120的外侧，从而能够进一步确保导通层120各个位置的一致性。具体地，相关技术中在绕设发热丝130时，均采用手动安装，从而导致发热丝130和导通层120的组装一致性差，且组装效率低。通过绕线机将发热丝130绕设于导通层120的外侧，能够有效克服由于手动安装发热丝130导致的一致性差的问题，提高产品组装效率，使得不同气溶胶产生装置的口感具有很好的一致性。
实施例四：

在实际应用中，支撑管110的材质包括金属材料、陶瓷材料、玻璃或工程塑料中的一种，从而确保支撑管110的结构强度，进而能够为导通层120提供有效的支撑。
值得说明的是，通孔112可以为圆孔或椭圆形孔，具体可以根据实际需要进行设置。且通孔112的数量也可以根据实际需要或具体气溶胶产生装置的大小进行设置。
在一个具体的实施例中，进一步地，本体111的内径a满足0.3mm≤a≤3mm。
在该实施例中，限定了本体111内径的取值范围，也即限定了导通腔宽度的取值范围。能够理解的是，本体111的内径若过小，即导通腔的宽度过小，则单位体积通入的气溶胶产生基质的量较小，降低气溶胶产生装置的雾化量。若本体111的内径过大，则使得发热体100的体积较大，一方面会占用气溶胶产生装置的内部空间，另一方面，还会导致气溶胶产生装置的体积较大，不利于产品的美观。通过将本体111的内径限定在0.3mm至3mm之间，能够在确保气溶胶产生装置雾化量的同时，提高产品的美观性。
在另一个具体的实施例中，进一步地，本体111的轴向长度b满足3mm≤b≤30mm。

在该实施例中，限定了通孔112孔径的取值范围，具体地，通孔112的孔径n满足0.01mm≤n≤3mm。能够理解的是，通孔112的孔径若过小，则不利于气溶胶产生基质的流通，降低气溶胶产生装置的雾化量。通孔112的孔径若过大，则降低支撑管110的结构强度，进而降低发热体100的使用寿命。通过 将通孔112的孔径限定在0.01mm至3mm之间，能够在确保气溶胶产生装置雾化量的同时，延长发热体100的使用寿命。
在实际应用中，导通层120包括多个毛细孔，通孔112的孔径小于本体111的内径，并大于导通层120的毛细孔直径，从而能够确保气溶胶产生基质的有效流通，进而确保气溶胶产生装置的雾化量。

进一步地，导通层120为整体编织结构，也就是说，导通层120由导通基质采用编织的方法制成编织结构，从而使得导通层120具有很好的完整性和一致性。相较于相关技术中将导通层120采用布片包裹式棉层而言，能够确保导通层120各个位置形态的一致性，进而确保具有该发热体100的气溶胶产生装置的雾化状态可控。而且，相较于相关技术中将导通层120采用环形海绵式棉 层而言，采用编织法形成的导通层120，可压缩性较小，从而使得导通层120被发热丝130缠绕部分与无发热丝130缠绕部分的厚度差异较小，进而使得导通层120具有很好的一致性，确保气溶胶产生装置的口感。
