Description

雾化器
本申请引用于2022年06月28日递交的名称为“雾化器”的第202221640744.6号中国专利申请，其通过引用被全部并入本申请。
技术领域
本申请涉及雾化技术领域，更具体的说，涉及一种雾化器。
背景技术
气溶胶是一种由固体或液体小质点分散并悬浮在气体介质中形成的胶体分散体系，由于气溶胶可通过呼吸系统被人体吸收，为用户提供一种新型的替代吸收方式。雾化器是指将存储的可雾化的介质通过加热或超声等方式形成气溶胶的装置。
加热不燃烧的气溶胶生成基质是一种利用特殊热源、基质进行加热(加热温度在500℃以下甚至更低)，加热时雾化基质中的各种物质通过挥发产生气溶胶来满足吸烟者需求的一种新型基质。加热不燃烧的气溶胶生成基质在抽吸过程中没有明火和烟灰产生，对环境较为友好，可以在为使用者提供良好的使用体验，同时减少常规基质在燃烧中高温裂解产生有害物质，从而减少对使用者的身体伤害。
现有的用于雾化加热不燃烧的气溶胶生成基质的雾化器具具有一加热腔，在将雾化介质插入加热腔后，外界气流从雾化基质的底部进入气溶胶生成基质中，气流与气溶胶生成基质内部加热产生的香味等有效物质混合后被用户抽吸。但流入气溶胶生成基质底部的气流降低了气溶胶生成基质的温度，气溶胶生成基质内的物质不能被充分烘烤，其内有效物质无法完全释放，从而导致雾化器具输出的气溶胶中含有的有效物质的量偏小，降低了雾化器具的体验感。

在本申请的描述中，需要理解的是，术语“中心”、“纵向”、“横向”、“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”、“顺时针”、“逆时针”、“轴向”、“径向”、“周向”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，仅是为了便于描述本申请和简化描述，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。
此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。在本申请的描述中，“多个”的含义是至少两个，例如两个，三个等，除非另有明确具体的限定。
在本申请中，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”、“固定” 等术语应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或成一体；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系，除非另有明确的限定。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在本申请中的具体含义。

参阅图1及图2，本申请提供了一种雾化器100/200，包括用于加热雾化气溶胶生成基质300。气溶胶生成基质300呈柱状结构，包括沿轴向依次相连的基质段320、中空段340以及过滤段360，基质段320可在雾化器100/200的加热下产生气溶胶和其他有效物质，基质段320中产生的气溶胶和其他有效物质经过中空段340和过滤段360的汇流、过滤作用后流出以供使用者吸食。
进一步地，为了使气溶胶生成基质300中的有效物质充分释放，中空段340的侧壁开设有第一揽气孔341，气溶胶生成基质300外的气流可通过第一揽气孔341进入中空段340内。优选地，中空段340开设有多个第一揽气孔341，多个第一揽气孔341沿周向间隔排布。基质段320靠近中空段340的一端的侧壁开设有第二揽气孔321，气溶胶生成基质300外的气流可通过第二揽气孔321进入基质段320内。优选地，基质段320开设有多个第二揽气孔321，多个第二揽气孔321沿周向间隔排布。
雾化器100/200包括本体120/210及加热管140/230。本体120/210具有一端开口的容纳空间，加热管140/230为中空的管状结构，加热管140/230收容于容纳空间远离其开口的一端内，加热管140/230与本体120/210共同界定形成具有相对设置的开口端和封闭端的容纳腔160/250。容纳腔160/250的形状与气溶胶生成基质300的形状相匹配，包括由加 热管140/230界定形成的靠近封闭端的加热段161/252和由容纳空间界定形成的靠近开口端的容纳段163/254。
气溶胶生成基质300的一端插设于容纳腔160/250内，具体地，基质段320位于加热段161/252内，中空段340连接基质段320的一端位于加热段161/252内，中空段340的另一端和过滤段360连接中空段340的一端位于容纳段163/254内，过滤段360的另一端伸出容纳腔160/250的开口端。参见图4及图5，气溶胶生成基质300和容纳腔160/250的腔侧壁之间存在间隙以形成第一气流通道1632/2541和第二气流通道1634/2543，第一气流通道1632/2541连通第一揽气孔341，第二气流通道1634/2543连通第一气流通道1632/2541和第二揽气孔321。作为一较佳的实施方式，气溶胶生成基质300与容纳腔160/250的腔侧壁之间的间隙为0.3mm-1mm，从而使气流可顺畅流动。
如此，气溶胶生成基质300外的气流可首先流入第一气流通道1632/2541，第一气流通道1632/2541中的一部分气流通过第一揽气孔341流入中空段340，另一部分气流则依经过第二气流通道1634/2543和第二揽气孔321进入基质段320，然后携带基质段320中生成的气溶胶和其他有效物质进入中空段340与中空段340中的气流汇流。
由此可见，由于气流的主要流动路径未经过容纳腔160/250的加热段161/252和基质段320远离中空段340一端的底部，因此加热段161/252内的烘烤温度较为稳定，不会因温度的显著变化导致气溶胶生成基质300的烘烤程度发生变化，气溶胶生成基质300可在容纳腔160/250内被充分烘烤，其中的有效物质可充分释放，改善了生成的气溶胶的口感，有效提高了雾化器100/200的使用体验。
如图1、图3及图4所示，本申请的第一实施例提供了一种雾化器100，该雾化器100的第一气流通道1632与外界环境连通，流入第一气流通道1632的气流来自于外界环境中的空气。
具体地，在第一实施例中，第一气流通道1632沿周向环绕气溶胶生成基质300，并在气溶胶生成基质300的轴向上，自容纳腔160的开口端延伸至第一揽气孔341的所在位置。第二气流通道1634沿周向环绕气溶胶生成基质300，并在气溶胶生成基质300的轴向上，自第一揽气孔341所在位置延伸至第二揽气孔321所在位置。
如此，外界环境中的气流可从容纳腔160的开口端流进入第一气流通道1632，然后其中一部分气流通过第一揽气孔341流入气溶胶生成基质300的中空段340内，另一部分气流则继续沿气溶胶生成基质300的轴向流动，直至通过第二揽气孔321进入基质段320内。
进一步地，为了避免气流从气溶胶生成基质300的基质段320远离中空段340一端的 底部进入基质段320，基质段320远离中空段340一端的端壁抵持于容纳腔160形成封闭端的腔底壁。如此，气溶胶生成基质300的底部被容纳腔160的腔底壁密封，外界气流无法通过气溶胶生成基质300的底部进入基质段320，从而不会影响基质段320内的温度。
在一些实施例中，雾化器100还包括至少两个支撑件180，每个支撑件180凸设于容纳腔160的腔侧壁并位于第二气流通道1634内，相邻两个支撑件180之间形成供气流流过的通道，在一些实施例中，所述通道具体表现为连通槽。如此，支撑件180可对气溶胶生成基质300起到限位作用，避免气溶胶生成基质300在容纳腔160内晃动，而且可防止气溶胶生成基质300在抽吸过程中被带出。与此同时，第二气流通道1634内的气流可从相邻两个支撑件180之间的通道流过，因此支撑件180的设置不会阻碍气流流动。可以理解，支撑件180的数量、形状以及设置位置不限，可根据需要设置以满足不同要求。
如图2所示，本申请的第二实施例提供一种雾化器200，该雾化器200还包括设于本体210内的雾化组件290，雾化组件290可雾化液态的气溶胶生成基质300以生成气溶胶，流入第一气流通道2541的气流来自于雾化组件290。
具体地，容纳腔250的腔侧壁靠近开口端的一侧开设有连通第一气流通道2541的第一进气孔，本体210还开设有进气通道，进气通道的一端连通雾化组件290，进气通道的另一端连通第一进气孔。第一气流通道2541沿周向环绕气溶胶生成基质300，并在气溶胶生成基质300的轴向上，自第一进气孔的开设位置延伸至第一揽气孔341的所在位置。第二气流通道2543沿周向环绕气溶胶生成基质300，并在气溶胶生成基质300的轴向上，自第一揽气孔341所在位置延伸至第二揽气孔321所在位置。
如此，雾化组件290生成的气溶胶可通过进气通道经过第一进气孔进入第一气流通道2541，然后其中一部分气溶胶通过第一揽气孔341流入气溶胶生成基质300的中空段340内，另一部分气溶胶则继续沿气溶胶生成基质300的轴向流动，直至通过第二揽气孔321进入基质段320内。
在一些实施例中，容纳腔250形成封闭端的腔底壁还开设有连通进气通道的第二进气孔，雾化组件290中生成的气溶胶中的一部分可通过进气通道、第二进气孔进入基质段320内，然后携带基质段320内产生的气溶胶和其他有效物质进入中空段340。
在一些实施例中，雾化器200还包括密封支撑件270，密封支撑件270凸设于容纳腔250的腔侧壁靠近开口端的一侧并沿周向环绕气溶胶生成基质300以封闭容纳腔250。由于容纳腔250相对于外界环境密封设置，因此流入气溶胶生成基质300内的气流均来源于雾化组件290。
上述雾化器100/200，与开设有第一揽气孔341和第二揽气孔321的气溶胶生成基质300配合形成连通第一揽气孔341的第一气流通道1632/2541和连通第二揽气孔321的第二气流通道1634/2543，有别于全部从气溶胶生成基质300的基质段320远离中空段340一端的底部进气的方案，本申请中的气流的主要流动路径未经过基质段320，因此烘烤温度稳定，对气溶胶生成基质300的烘烤更加稳定，气溶胶生成基质300中的有效物质不断释放并通过抽吸产生的负压流出，具有更大的出雾量，且气溶胶具有更好的口感，使得用户具有更好的使用体验。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
