Description

一种超声波电子烟雾化芯、雾化器及超声波电子烟 技术领域
本发明属于电子烟技术领域，特别涉及一种超声波电子烟雾化芯、雾化器及超声波电子烟。
背景技术
现有的超声波电子烟包括供电单元、供油单元和雾化芯。其中，雾化芯包括导油棉、雾化腔和超声波雾化片，超声波雾化片设于雾化腔内，雾化芯还设有连通电子烟进气道与雾化腔的进气口，连通电子烟出气道与雾化腔的出气口；供油单元包括油仓及出油孔，油仓依次通过出油孔、导油棉与超声波雾化片的雾化面相连通；供电单元内设有用于为电子烟供电的电源，以及控制电子烟工作的主板。
超声波电子烟工作时，油仓内的烟油通过出油孔导至超声波雾化片的雾化面，超声波雾化片雾化烟油产生烟雾并充盈在雾化腔内。气流从进气道通过进气口进入雾化腔，将雾化腔内的烟雾依次通过出气口、出气道及吸嘴带出，供用户吸食。
现有的超声波电子烟具有以下缺点：
第一，由于超声波雾化片在雾化过程中会有一部分烟油没有被充分雾化成烟雾，从而在导油棉的雾化部区域有部分烟油飞溅。由于现有技术中，用于连通进气道与雾化腔的进气口的位置设置随意，导致这些飞溅的烟油容易通过进气口滴落进进气道内，从而影响气流的正常流通。
第二，在用启动咪头控制的超声波电子烟中，启动咪头的感测头设于启动道内，其中启动道与进气道相连通。当进气道内有气流通过时，启动道内的气压改变，启动咪头的感测头感测到气压变化后，超声波电子烟启动工作。如果进气道内有烟油滴，则烟油滴可能顺着进气道流至启动道内，甚至咪头被烟油沾湿，启动道被堵塞，从而引起启动道内气压不变化或者变化慢，影响启动咪头的灵敏度和使用寿命。
第三，超声波电子烟雾化器没有实现模块化，维修和使用成本高，如，油仓内的烟油没有处于密封状态，烟油容易变质；导油机构或超声波雾化片损坏过后，更换困难，维修成本高。
发明内容
本发明的目的在于，针对上述现有技术的不足，提供一种超声波电子烟雾化芯、雾化器及超声波电子烟。
为解决烟油滴容易飞溅至进气道内的技术问题，本发明所采用的技术方案是：
一种超声波电子烟雾化芯，包括雾化座，雾化座内设有导油棉、雾化腔和超声波雾化片，超声波雾化片设于雾化腔内，导油棉的雾化部与超声波雾化片的雾化面相接触；雾化腔开设进气口与出气口；进气口与电子烟的进气道连通，出气口与电子烟的出气道连通；其特点是进气口侧壁与超声波雾化片雾化面之间的最小距离比导油棉的雾化部的厚度大h。
借由上述结构，由于雾化腔的进气口高出与超声波雾化片相接触的导油棉的雾化部，因而在超声雾化的过程中可以防止雾化腔中飞溅形成的烟油滴飞溅到进气口，或者可以防止在不吸烟时，超声波雾化片表面上的烟油从进气口流出；因此进而可以避免用户再次吸烟时存储在进气道内的烟油被吸到口腔。
作为一种优选方式，h的取值范围为0.5mm～30mm，烟油滴不会飞溅到进气口和进气道内，同时不会影响烟雾带出效果。
作为一种优选方式，所述进气道绕超声波雾化片的周边设置，进气道的轴向 与超声波雾化片垂直，快速将超声波雾化片雾化过程中产生的热量被进气道流动空气带走，减少雾化芯过烫而影响超声波雾化片本身的雾化效率。
作为一种优选方式，所述出气口设于超声波雾化片雾化面的中心区域上方。
由于出气口设置在超声波雾化片雾化面的中心区域上方，从而超声雾化出来的烟雾直接被出气口送走，因此可以减少烟雾热量的损失，提高烟雾口感。
进一步地，所述雾化座上设有通管，所述通管连通外界及导油棉。
与上述结构相对应，雾化芯对应的供油单元上设有密封油仓的密封膜，在生产过程中，供油单元的油仓预先注射好烟油，在使用时连接雾化芯及供油单元，在连接过程中，雾化芯上的通管刺破密封膜，从而油仓与导油棉相通，油仓内的烟油从通管流到导油棉上，进而导至超声波雾化片的雾化面上进行超声雾化产烟雾。可见，在雾化芯上的通管没有刺破供油单元的密封膜时，烟油处于密封状态，因而烟油不易变质，运输方便。当需要吸烟时，连接雾化芯和供油单元，通过通管刺破供油单元的密封膜，油路即导通，使用方便。当油仓内的烟油耗尽时，将供油单元拆除并更换新的供油单元，干净卫生，同时也可以避免多次注油带来的漏油风险。
进一步地，雾化座内还设有弹性座，弹性座的中心设有通孔，所述导油棉包括设于雾化部侧边的折弯边，雾化部穿过通孔并与超声波雾化片的雾化面接触，折弯边设于弹性座的顶面与雾化座内顶面之间，折弯边顶面与通管连通。
借由上述结构，折弯边设于弹性座的顶面与雾化座内顶面之间，折弯边顶面与通管连通，因而容易吸收通管排出的烟油。
进一步地，所述弹性座顶面开设若干与折弯边相对的透气槽。
借由上述结构，折弯边将透气槽覆盖，油仓外的气体经过透气槽和通管进入到油仓内，实现油仓内烟油和气体置换，从而使得通管排出烟油更加顺畅，有足够的烟油被导油棉吸收。
基于同一个发明构思，本发明还提供了一种超声波电子烟雾化器，包括供油单元，供油单元包括油仓及出油孔，其特点是还包括所述的超声波电子烟雾化芯，所述雾化芯与供油单元可拆卸相连；油仓通过出油孔与导油棉相通。
为解决烟油容易变质的技术问题，所述雾化座上设有通管，所述出油孔内设有可被通管刺破的密封膜；当供油单元与雾化芯相连时，通管伸入出油孔内并刺破密封膜，同时通管连通油仓及导油棉。
基于同一个发明构思，本发明还提供了一种超声波电子烟，包括供电单元，其特点是还包括所述的超声波电子烟雾化器，所述供电单元与雾化器可拆卸相连。
借由上述结构，将超声波电子烟分成供电单元、供油单元和雾化芯3个模块，每个模块之间可以相互拆卸，结构简单，使用和维护成本低，使用方便，提升用户体验。
为解决烟油滴容易进入启动道内影响启动咪头的灵敏度及使用寿命的技术问题，所述供电单元包括外壳，外壳内设有启动道和用于控制电子烟工作的启动咪头，启动咪头的感测头设于启动道内；供电单元与雾化器相连时，进气道与启动道相通。
使用超声波电子烟时，启动道与进气道对齐连通，在吸烟时，进气道和启动道内的气压都发生了变化，从而启动咪头触发启动电子烟工作。由于烟油滴不会从进气口进入进气道，因而也不会进入启动道，从而保证了启动咪头的工作灵敏度以及使用寿命。
进一步地，所述外壳上设有插槽，所述雾化座上设有与所述插槽相配合的导向骨。
借由上述结构，导向骨用作将雾化芯装入供电单元的手持部，连接雾化芯与供电单元时，将导向骨插入插槽内，保证启动道与进气道对齐且连通，防止二者对位错开而影响启动咪头的灵敏度。
与现有技术相比，本发明具有以下有益效果：
第一，雾化产生的烟油滴不会通过雾化腔的进气口进入进气道，保证进气效果，同时也可以避免用户再次吸烟时吸食到进气道内的烟油滴的现象。
第二，雾化产生的烟油滴不会通过进气道进入启动道，启动咪头灵敏度高，使用寿命长。
第三，烟油处于密封状态，烟油不易变质，结构简单，使用方便，使用和维修成本低。
第四，采用模块化设计，拆装方便，使用和维修成本低。

具体实施方式
如图1至图9所示，超声波电子烟雾化芯12包括雾化座1，雾化座1内设有导油棉2、雾化腔3和超声波雾化片4，超声波雾化片4设于雾化腔3内，导油棉2的雾化部201与超声波雾化片4的雾化面相接触；雾化腔3开设进气口5与出气口6；进气口5与电子烟的进气道7连通，出气口6与电子烟的出气道8连通；进气口5侧壁与超声波雾化片4雾化面之间的最小距离比导油棉2的雾化部201的厚度大h。h的取值范围为0.5mm～30mm，优选h的取值范围10mm～15mm，在这样的距离情况，不吸烟时，超声波雾化片上的烟油也不会从进气口溢出。其中，进气口5侧壁与超声波雾化片4雾化面之间的最小距离，即为进气口5侧壁周圈与超声波雾化片4雾化面之间的最小距离，具体到本实施例中，如图8所示，该最小距离即为进气口5侧壁最低点到超声波雾化片4雾化面之间的距离。
由于雾化腔3的进气口5高出与超声波雾化片4相接触的导油棉2的雾化部201，因而在超声雾化的过程中可以防止雾化腔3中飞溅形成的烟油滴飞溅到进气口5并且进入到进气道7内，避免堵塞进气道7或者随进气道7内的气流进入 用户口腔影响烟雾口感。
所述进气道7绕超声波雾化片4的周边设置，带走超声雾化过程中产生的热量，减少雾化芯12发烫；进气道7的轴向与超声波雾化片4垂直，进气道7轴向延伸到雾化芯12的底部。
所述出气口6设于超声波雾化片4雾化面的中心区域上方。由于出气口6设置在超声波雾化片4雾化面的中心区域上方，从而超声雾化出来的烟雾直接被出气口6送走，因此可以减少烟雾热量的损失，提高烟雾口感。
所述雾化座1上设有通管102，所述通管102连通外界及导油棉2。雾化芯12对应的供油单元10上设有密封油仓13的密封膜1402，在生产过程中，供油单元10的油仓13预先注射好烟油，在使用时连接雾化芯12及供油单元10，在连接过程中，雾化芯12上的通管102刺破密封膜1402，从而油仓13与导油棉2相通，油仓13内的烟油从通管102流到导油棉2上，进而导至超声波雾化片4的雾化面上进行超声雾化产烟。可见，在雾化芯12上的通管102没有刺破供油单元10的密封膜1402时，烟油处于密封状态，因而烟油不易变质，运输方便。当需要吸烟时，连接雾化芯12和供油单元10，通过通管102刺破供油单元10的密封膜1402，油路即导通，使用方便。当油仓13内的烟油耗尽时，将供油单元10拆除并更换新的供油单元10，干净卫生，同时也可以避免多次注油带来的漏油风险。
雾化座1内还设有弹性座9(由硅胶制作而成)，弹性座9的中心设有通孔901，所述导油棉2包括设于雾化部201侧边的折弯边202，雾化部201穿过通孔901并与超声波雾化片4的雾化面接触，折弯边202设于弹性座9的顶面与雾化座1内顶面之间，折弯边202顶面与通管102连通。折弯边202设于硅胶座的顶面与雾化座1内顶面之间，折弯边202顶面与通管102连通，因而容易吸收通管102排出的烟油。
所述弹性座9顶面开设若干与折弯边202相对的透气槽902。折弯边202将透气槽902覆盖，油仓13外的气体经过透气槽902和通管102进入到油仓13内，实现油仓13内烟油和气体置换，从而使得通管102排出烟油更加顺畅，有足够的烟油被导油棉2吸收。
雾化座1内设有电极套18，超声波雾化片4通过缓冲垫19固设于电极套18内。电极套18底部设有电极座20，缓冲垫19设于电极座20上，缓冲垫19由硅胶制作而成，因此有弹性缓冲作用，同时也可以密封烟油渗漏到超声波雾化片4的底面。超声波雾化片4的顶面为雾化面，其位于底面的一电极层与弹性电极21相抵接。超声波雾化片4的另一电极层通过电极套18与电极座20电连接。电极座20与弹性电极21之间通过绝缘环22绝缘相连。
雾化座1内还设有弹簧23，弹簧23一端与雾化座1内顶面抵接，弹簧23另一端与导油棉2的雾化部201抵接，保证雾化部201与超声波雾化片4雾化棉的可靠接触。
本实施例中，弹性座9套接在电极套18顶部，电极套18顶部设有对弹性座9限位的限位部1801。弹性座9上开设第一过气槽903，电极套18上开设第二过气槽1802，雾化座1内壁上开设进气槽101，进气槽101与电极套18外壁之间形成所述进气道7。所述出气道8设于雾化座1的顶部中央。
弹性座9上的固定臂904套住电极套18的外部，使得第一过气槽903与第二过气槽1802对位相通。第二过气槽1802与弹性座9之间形成所述进气口5，第二过气槽1802最低端与雾化部201顶面之间的距离为h。
气流从进气道7进入，依次经过第一过气槽903、第二过气槽1802进入雾化腔3，经雾化腔3内的烟雾经由出气口6和出气道8带出，供用户吸食。气流 方向如图8所示。
本发明所述的超声波电子烟雾化器包括供油单元10，供油单元10包括油仓13及出油孔1401，还包括所述的超声波电子烟雾化芯12，所述雾化芯12与供油单元10可拆卸相连；油仓13通过出油孔1401与导油棉2相通。
所述雾化座1上设有通管102，所述出油孔1401内设有可被通管102刺破的密封膜1402；当供油单元10与雾化芯12相连时，通管102伸入出油孔1401内并刺破密封膜1402，同时通管102连通油仓13及导油棉2。
本实施例中，供油单元10包括吸嘴盖24，油仓13设于吸嘴盖24内，吸嘴盖24底部设有用于对油仓13封口的底座14，底座14与油仓13之间还设有密封垫25，用于加强烟油密封效果。
所述出油孔1401开设于所述底座14上。
底座14底部还设有与吸嘴盖24相连的固定套26，所述固定套26为金属件，用于与供电单元11上的磁性件27相配合，方便供油单元10与供电单元11的对位安装。
本发明所述的超声波电子烟包括供电单元11，还包括所述的超声波电子烟雾化器，所述供电单元11与雾化器可拆卸相连。将超声波电子烟分成供电单元11、供油单元10和雾化芯12共3个模块，每个模块之间可以相互拆卸，结构简单，使用和维护成本低，使用方便，提升用户体验。
所述供电单元11包括外壳15，外壳15内设有启动道16和用于控制电子烟工作的启动咪头17(如气流传感器等)，启动咪头17的感测头设于启动道16内；供电单元11与雾化器相连时，进气道7与启动道16相通。使用超声波电子烟时，启动道16与进气道7对齐连通，在吸烟时，进气道7和启动道16内的气压都发生了变化，从而启动咪头17触发启动电子烟工作。由于烟油滴不会从进气口5进入进气道7，因而也不会进入启动道16，从而保证了启动咪头17的工作灵敏度以及使用寿命。
所述外壳15上设有插槽1501，所述雾化座1上设有与所述插槽1501相配合的导向骨103。导向骨103用作将雾化芯12装入供电单元11的手持部，连接雾化芯12与供电单元11时，将导向骨103插入插槽1501内，保证启动道16与进气道7对齐且连通，防止二者对位错开而影响启动咪头17的灵敏度。
外壳15内设有支架28，支架28顶部设有磁性件27，用于与固定套26相配合，提供供油单元10与供电单元11相连的磁吸力。
雾化座1上导向骨103上部还设有夹持部104，用于在供油单元10与雾化芯12装配时夹持住吸嘴盖24的底部，增加连接可靠性。
本实施例中，雾化座1与外壳15之间形成与进气道7相通的进气缝隙29，用于为外界空气进入电子烟提供入口。
外壳15内还设有电池30、主板31、第一电池电极32、第二电池电极33，其中，电池30用于为电子烟提供工作电源；启动咪头17与主板31电连接，主板31用于控制电子烟的工作；主板31、第一电池电极32、第二电池电极33均固设于支架28上，第一电池电极32和第二电池电极33固设于支架28顶部，在雾化芯12与供电单元11相连时，第一电池电极32与电极座20相抵接，第二电池电极33与弹性电极21相抵接，从而实现雾化芯12与供电单元11之间的电连接。
上面结合附图对本发明的实施例进行了描述，但是本发明并不局限于上述的具体实施方式，上述的具体实施方式仅仅是示意性的，而不是局限性的，本领域的普通技术人员在本发明的启示下，在不脱离本发明宗旨和权利要求所保护的范围情况下，还可做出很多形式，这些均属于本发明的保护范围之内。
