Description

一种发热装置、雾化装置及电子烟
本申请要求于2020年11月24日提交中国专利局、申请号为202022752275.4、申请名称为“一种发热装置、雾化装置及电子烟”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
本申请涉及电子烟领域，尤其涉及一种发热装置、使用该发热装置的雾化装置及电子烟。
背景技术
由于烟草燃烧产生的烟雾中存在尼古丁、焦液等多种危害健康的物质，因此吸烟成为了当今世界最大的可预防死亡原因，而且吸烟者身边的人群吸入二手烟也会对身体造成伤害。因此随着科技的进步与人们对健康的日益重视，电子烟的使用越来越广泛。电子烟是一种通过加热烟油产生烟雾供用户吸食的电子产品，其一般包括雾化装置和电源装置两个部分；电源装置为雾化装置供电，通过将烟油雾化产生烟雾，相比于烟丝的直接燃烧，有效减少了有害物质的产生，在一定程度上减弱了对吸烟者以及周围人群的伤害。
雾化装置作为电子烟的核心结构，主要包括储液腔、导油介质、发热装置、雾化腔和吸嘴等结构，储液腔中的烟油导入储液介质，发热装置作为加热元件用于对导油介质中烟油进行加热。当电源装置对发热装置供电时，发热装置升温加热导油介质中的烟油，从而实现烟油的雾化而产生烟雾。
常用的雾化装置中，发明人发现，储液腔、导油介质和发热装置为一体结构。发热装置在使用过程中出现老化或烧坏等情况需要更换发热装置时、用户想更换不同口味的烟油、或者雾化装置中烟油用尽需要更换时，由于储液腔、导油介质和发热装置为一体结构，则需要将整个雾化装置拆除更换。特别是烟油用尽需要更换的情况，其属于正常使用，且发生频率较高；若每一次都将带有发热装置的一体结构全部更换，将造成耗材无法重复利用，带来很大的资源浪费，导致用户使用成本过高，也不环保。
另外，发热装置与储液腔为一体结构，二者的装配间隙随着时间的推移，特别是在运输过程中，经常出现烟油泄露的情况。因此，传统的发热装置与储液腔的一体式结构，在零部件及产品运输过程中不渗漏是一个急需解决的问题。
市面上存在的一体式结构中，发热装置一般是棉绕发热丝或者陶瓷底部烧结发热丝等方式制作而成，棉绕发热丝经常发生烧糊需要丢弃更换的情况；而陶瓷烧结发热丝的方案，由于陶瓷的碳化会严重影响烟油雾化的效果，抽吸口感差。

实施例1
如图1至图10所示，本实施例公开的电子烟包括电源装置30和雾化装置。雾化装置包括储液装置10和雾化座20，雾化座20上设置有发热装置21，且雾化座20上成型有雾化腔22，雾化座20上设置有吸嘴23和气道24，吸嘴23与雾化腔22通过气道24连通；如此，储液装置10内的烟油经雾化座20上的发热装置21雾化后，烟雾容纳在雾化腔22内；使用者通过吸嘴23往外吸气，雾化腔22内的烟雾受吸力作用，经气道24传递至吸嘴23，被使用者由吸嘴23吸出。
如图8所示，吸嘴23设置在雾化座20的右端，雾化腔22和发热装置21位于雾化座20的左侧，储液装置10安装在雾化座20和发热装置21的上方；储液装置10包括储液腔11和位于储液腔11与发热装置21之间的导油介质12，导油介质12与发热装置21配合设置。此处，配合设置指导油介质12位于发热装置21上方，且导油介质12靠近发热装置21设置或者与导油介质12接触设置，以能够实现发热装置21对导油介质12上的烟油进行加热为目标。
在本实施例中，为了便于制作并保证储液腔11的完整性，储液装置10在 加工过程中，一体注塑成型有储液腔11。此外，也可以采用吹塑的方式，在储液装置10内加工成型储液腔11。
本实施例中，为了保证在更换过程中，耗材的重复利用和资源节省，同时降低用户成本和实现环保目标，储液装置10可拆卸的安装在带有发热装置21的雾化座20上。储液装置10与发热装置21分开设置，在需要更换其中任意一者时，可以单独更换。
为进一步提高安装拆卸的便捷性和高效性，如图6或图9所示，本实施例中的雾化座20上设置有发热装置支架25，发热装置21安装在发热装置支架25上。组装过程中，先将发热装置支架25固定在雾化座20上，再将发热装置21安装在发热装置支架25上。更具体的，发热装置21可拆卸的安装在发热装置支架25上；如此，可以实现对装置的单独安装和拆卸更换。
更具体的，为了方便储液装置10与雾化座20的安装和拆卸，储液装置10和雾化座20可以采用卡扣的方式连接。卡扣连接方式，以及卡扣结构的设计，在机械领域都是常用的设计，在此不再赘述。
同时，为方便将储液装置10从雾化座20上拆卸，在储液装置10上设置有用于拆卸的拉手位。需要对储液装置10进行拆卸时，使用者可以由拉手位用力，将储液装置10与雾化座20的连接拆除，储液装置10脱离雾化座20。
如图8所示，储液装置10的下侧设置有两个导油孔13，导油介质12封闭导油孔13。储液腔11内的烟油，向下经导油孔13浸润到导油介质12，再由发热装置21进行加热雾化。在其他一些实施例中，导油孔13可以设置为三个、四个或者更多。
导油介质12封闭导油孔13的方式，可以是平铺在介质安装槽14内，完全覆盖并封闭导油孔13；也可以将导油介质12的至少部分伸入到导油孔13内，以封闭导油孔13；更进一步的，可以将导油介质12的至少部分穿过导油孔13，经导油孔13伸入到储液腔11内。
导油孔13四周设置有介质安装槽14，具体的，导油孔13四周围设有边框，边框围成介质安装槽14，导油介质12安装在该介质安装槽14内。
在介质安装槽14远离导油孔13的一侧，即附图8中介质安装槽14的下侧开口处，封装有铝塑膜141，用于将导油孔13和导油介质12密封在介质安装槽14内，保证其密封性。具体的，导油孔13四周围设的边框下侧进行封膜，成型上述封口的铝塑膜141。作为备选方案，介质安装槽14远离导油孔13的一侧还 可以用螺纹瓶盖或者卡扣的方式实现密封。
为进一步提高密封性能，在储液装置10与雾化座20配合的位置设置密封圈19，以保证安全后储液装置10与雾化座20之间的密封性。同时，为了便于安装以及提升密封圈19的稳定性，在储液装置10与雾化座20配合的位置设置有密封槽，密封圈19安装在该密封槽内。
如图8所示，储液装置10包括内部成型有储液腔11的腔本体16，上述导油孔13开设在腔本体16的一侧，如图8中的腔本体16的下侧开设有导油孔13。而在腔本体16的一端端部设置有注油口，如图8，腔本体16的右端设置有注油口；为了提升储液腔11的密封性，在注油口内安装有用于密封注油口的油口密封件17，且在油口密封件17外侧设置有封装盖板18。其中，油口密封件17为硅胶密封件，封装盖板18为塑胶盖板。
本实施例中，导油介质12为一种具有导油功能的介质，可以使棉花、无纺布或者纤维绳子。储液腔11内的烟油从导油孔13漏出时，烟油会饱和、均匀的分布在导油介质12上，以便发热装置21对导油介质12上的烟油进行雾化。
如图4所示，发热装置21包括发热体211和发热支架212，发热体211平铺在所述发热支架212上。可以理解的，导油介质12为片状，发热装置21成型为与导油介质12大面对大面设置的构造，比如大面对大面平行设置；如此，可以增加发热装置21与导油介质12的接触面积，提高雾化效率并提升雾化效果。为了进一步保证雾化效率的提高和雾化效果的提升，发热装置21上的发热体211也要实现与导油介质12最大化的面对面接触；发热体211平铺在发热支架212上，能够最大化的实现发热体211与导油介质12的面对面接触。类似于羽毛球拍，当发热体211为丝状发热体时，丝状发热体的平铺状态，即为羽毛球拍的拉线结构，而发热支架212则类似于羽毛球拍拉线而成的球网外侧的金属圈。
更具体的，为了实现发热体211与导油介质12的直接接触，在发热支架212中间位置设置镂空结构，发热体211则平铺在发热支架212的镂空处。
本实施中，如图4所示，发热体211为丝状发热体，丝状发热体平铺在发热支架212上。
发热支架212为中间位置镂空的矩形框架，发热体211为发热丝，发热丝呈网状穿设在矩形框架内。
在本实施例中，矩形框架相对的两个边为陶瓷基座213，发热丝的两端烧结 在陶瓷基座213上。
矩形框架相对的两侧设置有第一电极和第二电极，发热丝连接在第一电极和第二电极之间。该第一电极和第二电极用于将发热丝与电源装置30连通。
在本实施例中，雾化座20上设置有第一电极片26和第二电极片27，第一电极片26用于连接第一电极，第二电极片27用于连接第二电极。同时，第一电极片26的另外一端连接电源装置30的正极，第二电极片27的另外一端连接电源装置30的负极。电源装置30安装在雾化装置上时，通过第一电极片26和第二电极片27实现为发热装置21供电。
如图5所示，雾化座20顶部设置有吸嘴23，中间设置有槽位，发热装置支架25则安装在中间的槽位内。
在本实施例中，导油介质12安装在介质安装槽14内，发热装置21与发热装置支架25装配在一起，压进雾化座20中间设置的槽位中，再将储液装置10与雾化座20扣合在一起，此时导油介质12刚好与发热装置21上的发热体211有效接触，以实现发热装置21对导油介质12中浸润的烟油加热。
本实施例中，发热支架212中间镂空，装配发热体211后，中间镂空的下部位置，可以作为气道24的一部分。发热体211与发热支架212烧结在一起，发热支架212以是陶瓷、耐高温的塑胶或硅胶、石英、木质结构等。此外，发热体211为发热丝时，还可以通过引脚穿孔的方式平铺固定在发热支架212上。更进一步，发热支架212还可以选择为金属材质，发热丝可以通过电焊的方式固定在发热支架212上。
在本实施例中，密封圈19为O型圈，也可以是截面为三角形、方形等其他形状的密封圈19。
本实施例提供的雾化装置，储液装置10与发热装置21是完全分离的两个部分，烟油用尽后，消费者只需要更换储液装置10，而发热装置21可以实现循环利用，降低了使用成本。
在本实施例中，发热丝设置在发热支架212的中间镂空位置，使得发热支架212无需具备导油功能，导油介质12上的烟油也能很好的与发热丝接触。
本申请的一个优选方案中，发热丝可以烧结在发热支架212上，导油介质12的两端经导油孔13插入到储液腔11内；发热装置21通过硅胶紧配的方式固定在发热装置支架25上，发热装置支架25也通过硅胶紧配的方式固定在雾化座20上。
本实施例中，通过热压的方式，将铝塑膜141封装在介质安装槽14远离所述导油孔13的一侧，起到密封作用。
本实施例中的多重密封方式，有效的解决了储液腔11在运输过程中会发生渗漏的情况，保证了密封性和安全性。
本实施例中，导油介质12安装在介质安装槽14内，然后用铝塑膜141封口；注油口采用硅胶的油口密封件17封装。通过两个针管刺穿硅胶的油口密封件17，一个针管注油，另一个针管做排气用；注油完成后，再用塑胶的封装盖板18铆压在硅胶的油口密封件17外侧。
实施例2
如图11至图13所示，本实施例中，电子烟的雾化装置，包括雾化座20和安装在雾化座20上的储液装置10，雾化座20上设置有发热装置21，同时，雾化座20上设置有开关装置28，且储液装置10上设置有控制装置15。开关装置28通过控制装置15的控制，实现闭合或关断。
当储液装置10安装在雾化座20上时，控制装置15触发开关装置28闭合，以接通发热装置21与电源装置30的电连接；当储液装置10从雾化座20上拆除时，控制装置15触发开关装置28关断，以断开发热装置21与电源装置30的电连接。
如图12和图13所示，控制装置15为金属片，开关装置28为设置在雾化座20上的第一探针281和第二探针282，储液装置10安装在上时，金属片的一端与第一探针281接触，另一端与第二探针282接触，第一探针281和第二探针282通过金属片导通；当储液装置10从雾化座20上拆除时，金属片与第一探针281和第二探针282都分离，第一探针281和第二探针282则断开电连接。
以上，通过第一探针281和第二探针282的导通与否，来控制电源装置30是否为发热装置21供电；当第一探针281和第二探针282导通时，电源装置30为发热装置21供电，发热装置21可以完成其加热动作；当第一探针281与第二探针282断开电连接时，电源装置30停止位发热装置21供电，发热装置21无法完成加热动作。
如此，即使在储液装置10取下，发热装置21无烟油可加热的情况下，使用者却执行抽吸加热的动作，也不会发生发热装置21干烧的情况，保证了发热装置21的使用寿命。
在本实施例中，电子烟的电源装置30中设置有控制器，该控制器用于控制 电源装置30是否为发热装置21供电，以执行雾化动作。第一探针281与控制器连接，第二探针282接地；第一探针281与第二探针282接通时，控制器可根据操作控制电源装置30向发热装置21供电；第一探针281和第二探针282断开电连接时，控制器控制电源装置30停止向发热装置21供电。
本实施例提供的电子烟，当储液装置10与雾化座20连接时，第一探针281和第二探针282接通，此时发热装置21才会与电源装置30实现电连接；当储液装置10取下时，第一探针281和第二探针282断开，此时发热装置21与电源装置30断开，电子烟不能工作，即使执行抽吸的其他操作，发热装置21也无法实现加热功能，保证安全性和发热装置21的使用寿命。
在本实施例中，雾化座20上设置有第一导电件和第二导电件，所述发热装置21上设置有第一电极和第二电极；所述第一导电件的一端与所述第一电极连接，另一端与电源装置30的正极连接；所述第二导电件的一端与所述第二电极连接，另一端与电源装置30的负极连接。
在本实施例中，控制装置15优选为金属片，金属片的形状不做限制，与第一探针281和第二探针282配合即可。第一导电件和第二导电件优选采用金属弹片。第一探针281和第二探针282为导电探针，其形状也不做限制，能够实现与金属片的配合即可。
本实施例中，电源装置30中设置有控制器(MCU)，第一探针281与控制器连接，第二探针282接地(GND信号)。当金属片同时接触第一探针281和第二探针282时，MCU检测到GND信号并作出相应处理，此时可通电，设备工作；当金属片与第一探针281和第二探针282分离时，设备断电。
以上所述仅为本申请的较佳实施例而已，并不用以限制本申请，凡在本申请的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本申请的保护范围之内。
