电子雾化装置用于雾化气溶胶生成基质，其可用于不同的领域，例如、医疗雾化、美容雾化、休闲吸食等领域。其中，电子雾化装置内通常设置有储液空间和雾化组件，储液空间内存储有气溶胶生成基质，气溶胶生成基质可以为药液、营养液或其他具有特殊香气的组合液态基质等，雾化组件用于在电子雾化装置工作时，雾化气溶胶生成基质以生成气溶胶，雾化组件的雾化方式可以为加热雾化或非加热雾化，其中，加热雾化包括电阻加热、电磁加热、激光加热、红外加热以及微波加热等；非加热雾化包括超声雾化、压力雾化、机械震动雾化以及压缩空气雾化等。然而，传统的单液腔电子雾化装置，即，电子雾化装置内只设置一个储液空间，储液空间容易受气溶胶生成基质含量的影响，导致对雾化组件的供液不均匀。而且，在电子雾化装置长期闲置或外界大气压发生变化时，储液空间内的气溶胶生成基质容易发生渗漏。
为了解决传统的电子雾化装置存在液体渗漏、供液不均等问题，参见图1-图3，图1是本申请提供的电子雾化装置的一实施例的结构示意图；图2是如图1所示电子雾化装置沿A-A线的剖视图；图3是本申请提供的电子雾化装置的另一实施例的剖视图。
本申请提供的电子雾化装置100，包括供液腔11、储液腔12、感应孔13、第一感应元件14、供液机构20和控制器件30。其中，第一感应元件14通过感应孔13检测供液腔11内的当前压力值P1，供液机构20用于驱动储液腔12内的液体向供液腔11供液，控制器件30电连接供液机构20和第一感应元件14；其中，控制器件30基于当前压力值P1与预设压力值P0的差值D1控制供液机构20，以驱动储液 腔12内的液体向供液腔11供液。
具体的，雾化组件10在雾化供液腔11内的气溶胶生成基质时，随着供液腔11内气溶胶生成基质逐渐消耗，供液腔11内的压力值同时也会减小，第一感应元件14通过感应孔13检测供液腔11的当前压力值P1，控制器件30基于第一感应元件14检测得到的当前压力值P1，与预设压力值P0进行比较，若当前压力值P1与预设压力值P0的差值D1不在预设范围，控制器件30控制供液机构20，以驱动储液腔12内的液体向供液腔11供液，从而保证供液腔11内的压力一直维持在预设压力范围，实现即用即供的供液效果，有效控制对雾化组件10的液体供给，保证均匀供液，且供液腔11和储液腔12双液腔设计，控制器件30基于供液腔11内的当前压力值P1与预设压力值P0的差值D1控制供液机构20驱动储液腔12内的液体向供液腔11供液，解决了传统的单液腔容易受外界大气压影响，发生的液体渗漏和供液不均匀的问题。
其中，第一感应元件14可以为气压传感器。气压传感器封盖于感应孔13远离供液腔11的一端，且感应孔13的另一端被供液腔11内的气溶胶生成基质所液封，以在感应孔13内形成空气柱。具体的，气压传感器与供液腔11通过感应孔13连接，且感应孔13的长度和直径合适时，感应孔13中会形成一段空气柱，将气压传感器与供液腔11隔离，当供液腔11内的压力发生变化时，例如，供液腔11内溶胶生成基质增多或减少时，或外界大气压发生变化时，此段空气柱的压力会相应地发生变化，而气压传感器对空气变化的灵敏度优于对液体的灵敏度，可以提高对供液腔11内的气压变化检测灵敏度，实现精确供液。
其中，感应孔13的横截面可以为圆形、椭圆形、矩形等，感应孔13沿直径方向的横截面尺寸小于等于5.0mm。具体的，若感应孔13的孔径太小，空气柱中的空气容易溶解到气溶胶生成基质中，从而无法形成空气柱。若感应孔13的孔径太大，空气柱中的空气容易挤入供液腔11，无法形成空气柱。只有当感应孔13的孔径和长度合适从而达到平衡时，会形成空气柱，且空气柱的长度会随着供液腔11内压力的变化而发生变化，气压传感器通过空气柱的压力变换检测供液腔11内的压力。
在一具体实施方式中，感应孔13沿直径方向的横截面呈圆形孔，圆形孔的直径大于等于0.3mm且小于等于5.0mm。例如，圆形孔的直径为0.3mm、2.0mm、4.0mm或5.0mm。
在一具体实施方式中，参见图2，考虑到感应孔13的气密性和液密性，感应孔13设置于供液腔11的侧壁上，感应孔13的长度大于等于1.0mm且小于等于50mm。具体可根据感应孔13的孔径进行相应设置，以使感应孔13的直径和长度合适从而形成空气柱为准。
当然，感应孔13还可以设置于电子雾化装置上的任意位置，只要使感应孔13的一端被第一感应元件14封盖，另一端被供液腔11内的气溶胶生成基质液封即可。
第一感应元件14也可以为液压传感器，供液腔11内的气溶胶生成基质通过感应孔13接触液压传感器。当第一感应元件14为液压传感器时，感应孔13的孔径、长度和设置位置不做限定，只要供液腔11内的气溶胶生成基质能够通过感应孔13直接接触到液压传感器，且避免气溶胶生成基质从感应孔13发生漏液即可。
需要说明的是，由于液压传感器是通过与液体直接接触来检测压力，因此，第一感应元件14为液压传感器时还有一个优点，电子雾化装置中可以不设置感应孔13，液压传感器直接设置于供液腔11内，省去了为电子雾化装置打感应孔的工艺，进一步防止漏液的情况发生。
具体的，在用户抽吸电子雾化装置100时，电子雾化装置100内的气流会发生改变，电子雾化装置100中还设置有气流感应件53，气流感应件53可以为频率硅麦或咪头，用于检测电子雾化装置100内的气流变化，气流感应件53与控制器件30电连接，控制器件30基于气流感应件53检测到电子雾化装置100内的气流发生变化，判断用户触发抽吸触发信号，控制雾化组件10雾化气溶胶生成基质，且控制第一感应元件14检测供液腔11内的当前压力值P1。
其中，预设压力值P0可以为用户刚触发抽吸触发信号时，第一感应元件14检测供液腔11的当前压力值P1作为预设压力值P0。或预设压力值P0为第一感应元件14在电子雾化装置100闲置阶段，即电子雾化装置雾化前，检测供液腔11内的压力值作为预设压力值P0。或预设压力值P0为预先设置在控制器件30内的数值。或预设压力值P0以实时检测的外界大气压力值P2作为预设压力值P0。
在一具体实施方式中，雾化组件10的上表面为雾化面，且雾化组件10具有用于将供液腔11内气溶胶生成基质导入雾化面的微孔。雾化组件10的下表面与供液腔11接触，雾化组件10的上表面与外界连通，供液腔11内与雾化组件10上表面存在的压力差会使气溶胶生成基质穿过雾化组件10内微孔到达上表面，使得供液腔11压力减小，最终使供液腔11与外界大气压力值P2达到平衡，由于在电子雾化装置100的闲置阶段，供液腔11内的压力随着时间的变化会与外界大气压力值P2逐渐趋于平衡，因此，以用户刚触发抽吸触发信号时第一感应元件14检测供液腔11的当前压力值P1作为预设压力值P0，或第一感应元件14检测供液腔11在雾化前的压力值作为预设压力值P0，相当于以外界大气压力值P2作为预设压力值P0。
需要注意的是，供液腔11内的压力随着时间的变化会与外界大气压力值P2逐渐趋于平衡需要一定的时间，当外界大气压发生变化时，短时间内供液腔11内的压力值与实际的外界大气压力值并不平衡，此时间段内，若检测供液腔11内的压力值作为预设压力值P0，可能会导致供液腔11内气溶胶生成基质渗漏或供液不足的问题。例如，此时间段内，若供液腔11内的压力值大于外界大气压力值P2，会挤压供液腔11内的气溶胶生成基质，而使气溶胶生成基质通过雾化组件10的微孔到达发热体上表面，出现渗漏的现象。若供液腔11内的压力值小于外界大气压力值P2，会使雾化组件10的微孔内的气溶胶生成基质回流至供液腔11，导致对雾化组件10供液不足，而使雾化组件10发生干烧，产生有毒有害气体。
因此，在一具体实施方式中，电子雾化装置100还包括第二感应元件(图未示)，第二感应元件电连接控制器件30，第二感应元件用于检测外界大气压力值P2，以实际的外界大气压力值P2作为预设压力值P0。
或在另一具体实施方式中，电子雾化装置100内不设置第二感应元件，第一感应元件14还用于检测外界大气压力值P2。具体的，在电子雾化装置100雾化之前，第一感应元件14检测供液腔11内的压力值和外界大气压力值P2，同时为控制器件30输出供液腔11内的压力值和外界大气压力值P2，或直接为控制器件30输出供液腔11内的压力值和外界大气压力值P2的压差D2。相比于电子雾化装置100中设置第一感应元件14和第二感应元件，本实施方式中提供的电子雾化装置100，成本更低。
可以理解的，以外界大气压力值P2作为预设压力值P0有三个好处，第一，控制器件30控制时可以直接用供液腔11内的当前压力值P1与外界大气压力值P2(预设压力值P0)的差值D1进行控制，使得控制更精确，而只检测供液腔11内的当前压力值P1的条件下，需要使供液腔11内的当前压力值P1和外界大气压力值P2达 到平衡时记录供液腔11内的压力值作为预设压力值P0，存在误判的风险；第二，外界大气压力值P2在不同的气温、海拔高度等情况下会发生变化，通过实时检测外界大气压力值P2并做修正，使得供液腔11内的压力值与外界大气压力值P2始终相同；第三，当外界大气压力值P2发生变化时，特别是外界大气压力值P2变小时，由于供液腔11内的压力值比外界大气压力值P2大，会挤压气溶胶生成基质，而使气溶胶生成基质通过雾化组件10的微孔到达发热体上表面，出现渗漏的现象，而有第二感应元件，可以检测到外界大气压力值P2变小，在雾化前利用供液机构对供液腔11内的压力进行控制，使供液腔11内的压力值与外界大气压力值P2达到新的平衡，实现防止液体渗漏和供液不足的效果。
在一情景中，控制器件30基于检测到的供液腔11内的压力值，和检测到的外界大气压力值P2进行比较，响应于供液腔11在雾化前的压力值和外界大气压力值P2的压差D2处于非预设范围，例如，用户携带电子雾化装置100由高海拔移动到低海拔，导致供液腔11内的压力值小于外界大气压力值P2且压差D2不在预设范围，此时，控制器件30控制供液机构20工作，以驱动储液腔12内的气溶胶生成基质向供液腔11供液，使得供液腔11内的压力值与外界大气压力值P2平衡。控制器件30响应于供液腔11在雾化前的压力值与预设压力值的压差D2处于预设范围，控制所述供液机构20关停。
在另一情景中，控制器件30基于检测到的供液腔11内的压力值，和检测到的外界大气压力值P2进行比较，响应于供液腔11在雾化前的压力值和外界大气压力值P2的压差D2处于非预设范围，例如，用户携带电子雾化装置100由低海拔移动到高海拔，导致供液腔11内的压力值大于外界大气压力值P2且压差D2不在预设范围，此时，控制器件30控制供液机构20工作，以驱动供液腔11内的气溶胶生成基质向储液腔12导液，使得供液腔11内的压力值与外界大气压力值P2平衡。控制器件30响应于供液腔11在雾化前的压力值与预设压力值的压差D2处于预设范围，控制所述供液机构20关停。
在一实施方式中，参见图3，电子雾化装置100还包括安装腔51，第一感应元件14和控制器件30设置于安装腔51，感应孔13的一端与供液腔11连通，感应孔13远离供液腔11的一端还连通安装腔51，第一感应元件14封盖于感应孔13远离供液腔11的一端。
其中，第一感应元件14可以设置于安装腔51的侧壁，通过导线与安装腔51内的控制器件30电连接。第一感应元件14与控制器件30也可以集成为一体，从而减少布线，进一步减少电路连接带来的短路、断路等问题，使得第一感应元件14与控制器件30之间电连接安全可靠。
在一实施方式中，参见图5，图5是如图2中所示的A区域的结构放大图。电子雾化装置100包括吸嘴组件40、雾化组件10和壳体50，雾化组件10连接吸嘴组件40，吸嘴组件40和雾化组件10配合界定出供液腔11；雾化组件10用于从供液腔11吸液并进行加热雾化或非加热雾化；壳体50与吸嘴组件40连接，壳体50设有安装腔51。
其中，壳体50与吸嘴组件40可以是一体成型或可拆卸连接，储液腔12可以设置于吸嘴组件40上或壳体50上，储液腔12也可以部分设置于吸嘴组件40，另外部分设置于壳体50，具体可根据实际需要选择。
在一实施方式中，参见图3，第一感应元件14设置于壳体50上，感应孔13包括设置于吸嘴组件40上的第一孔段131和设置于壳体50上的第二孔段132，第一 感应元件14封盖于第二孔段132朝向安装腔51的一端。
本实施例中，若考虑到感应孔13的气密性和液密性问题，壳体50与吸嘴组件40一体成型设计。从而避免壳体50与吸嘴组件40之间具有间隙，导致液体渗漏的情况的发生。
本实施例中，若考虑到成本问题，可以设置壳体50与吸嘴组件40可拆卸连接，由于第一感应元件14设置于壳体50且与吸嘴组件40分隔设置，因此在更换吸嘴组件40时，可以不更换第一感应元件14，第一感应元件14可以重复使用，从而减少成本。
在一实施方式中，参见图3和图5，吸嘴组件40包括吸嘴41和底座42，吸嘴41、雾化组件10以及底座42界定出供液腔11。具体的，雾化组件10连接吸嘴41并被吸嘴41夹持，吸嘴41上还设置有用于将气溶胶导出的雾化通道4110，雾化组件10的雾化面朝向雾化通道4110。底座42设置于吸嘴41靠近壳体50的一端，吸嘴41和底座42还用于与壳体50连接。
具体的，吸嘴41构成供液腔11的侧壁，底座42构成供液腔11的底壁、雾化组件10构成供液腔11的顶壁且用于雾化供液腔11内的气溶胶生成基质，当第一感应元件14设置于供液腔11的侧壁上时(参见图5)，感应孔13完全设置于吸嘴41的侧壁。当第一感应元件14设置于安装腔51时(参见图3)，感应孔13包括位于吸嘴41上的第一孔段131和位于壳体上的第二孔段132，第一孔段131的一端与供液腔11连通，另一端与壳体50上的形成的第二孔段132连通。
在一实施方式中，请结合图6，图6是如图1所示的电子雾化装置中吸嘴组件的结构爆炸图。第一感应元件14设置于供液腔11的侧壁上，供液腔11的侧壁外表面还设置有安装槽4120，第一感应元件14设置于安装槽4120内，感应孔13的一端与供液腔11连通，另一端位于安装槽4120底壁且被第一感应元件14所封盖。具体的，将第一感应元件14设置于安装槽4120内，一方面可以避免外力作用于第一感应元件14，使得第一感应元件14脱落或损坏；另一方面使得电子雾化装置100外形美观。
其中，当吸嘴组件40与壳体50可拆卸连接时，底座42和壳体50上均设置有连接结构，底座42与壳体50通过连接结构连接。例如，底座42靠近壳体50的一端设置有凸起，壳体50靠近底座42的一端设置有凹槽，吸嘴组件40与壳体50通过凸起和凹槽卡扣连接。在例如，底座42靠近壳体50的一端设置有正螺纹，壳体50靠近底座42的一端设置有反螺纹，吸嘴组件40与壳体50通过螺纹连接。当然，也可以是吸嘴41和壳体50上均设置有连接结构，底座42上不设置连接结构，具体可根据实际情况选择。
在一实施方式中，储液腔12设置于壳体50上，底座42被设置成在吸嘴组件40与壳体50连接时连通储液腔12和供液腔11，在吸嘴组件40与壳体50分离时封闭供液腔11。具体的，当储液腔12设置于安装腔51时，为了防止壳体50与吸嘴组件40分离导致供液腔11内的气溶胶生成基质流出供液腔11，例如，在吸嘴组件40与壳体50连接时，储液腔12通过底座42与供液腔11导通，从而不影响供液机构20驱动储液腔12内的液体向供液腔11供液。在更换一次性吸嘴组件40或给储液腔12注液的情景下，在吸嘴组件40与壳体50分离时，底座封闭供液腔11，从而避免供液腔11内的气溶胶生成基质流出供液腔11，造成浪费和卫生问题。可以理解的，底座42相当于单向阀，气溶胶生成基质只能流入供液腔11而不能流出。
在一实施方式中，参见图6和图7，图7是如图6所示的底座的结构爆炸图。 底座42包括端盖421和封闭件422，端盖421设有连通供液腔11的液孔4210，且与吸嘴41连接；封闭件422设置于端盖421上，且对应于液孔4210的位置设置有闭合缝4220，闭合缝4220在吸嘴组件40与壳体50分离时封闭液孔4210，在吸嘴组件40与壳体50连接时允许连通储液腔12和供液腔11。具体的，端盖421包括底板4211和环形凸缘4212，底板4211用于与壳体50连接，且底板4211与环形凸缘4212界定形成容置槽4213，封闭件422设置于容置槽4213内。其中，液孔4210设置于底板4211对应闭合缝4220的位置，封闭件422可以为硅胶或橡胶等具有弹性的材料。可以理解的，当储液腔12设置于安装腔51且壳体50与吸嘴组件40连接时，由于闭合缝4220具有一定的弹性，储液腔12部分可以穿过液孔4210和闭合缝4220，压缩封闭件422从而与供液腔11连通，当壳体50与吸嘴组件40分离时，储液腔12从闭合缝4220和液孔4210中脱离，封闭件422恢复，从而封闭闭合缝4220实现封闭供液腔11的目的。
在另一实施方式中，底座42上可以设置电动挡板(图未示)，电动挡板与控制器件30电连接，在吸嘴组件40与壳体50连接时，控制器件30控制电动挡板动作以使储液腔12和供液腔11，在吸嘴组件40与壳体50分离时，控制器件30控制电动挡板动作以封闭供液腔11。
在一实施方式中，请参见图5和图6，吸嘴41包括吸嘴座411和发热座412，吸嘴座411设置于发热座412背离底座42的一端，吸嘴座411上设有雾化通道4110；发热座412上设置有安装槽4120，发热座412与吸嘴座411连接，夹持雾化组件10。本实施方式中，将吸嘴41分为吸嘴座411和发热座412，用户可以根据卫生和磨损情况，更换吸嘴座411，而不必将整个吸嘴41更换，有利于健康且减少使用成本。
本实施方式中，电子雾化装置100上还设置有探测通道52，气流感应件53连接于探测通道52远离雾化通道4110的一端。具体的，探测通道52的一端连通雾化通道4110，另一端被气流感应件53所封盖。在用户抽吸电子雾化装置100时，雾化通道4110内的气流发生变化，例如，雾化通道4110内气压变为负压时，气流感应件53通过探测通道52检测雾化通道4110内的气流变化，控制器件30基于气流感应件53检测到的气流变化，控制雾化组件10、第一感应元件14以及第二感应元件工作。其中，气流感应件可以设置于吸嘴组件40上，也可以设置于壳体50。
参见图4，图4是如图1所示电子雾化装置沿B-B线的剖视图。气流感应件53设置于壳体50上，探测通道52包括第一探测段521和第二探测段522，第一探测段521设置于发热座412上，第二探测段522设置于壳体50上，第一探测段521的一端连通雾化通道4110，第一探测段521的另一端与壳体50上的第二探测段522一端连通，第二探测段522的另一端被气流感应件53所封盖。具体的，将气流感应件53设置于壳体上，例如，设置于壳体上且与控制器件集成，可以减少布线，使气流感应件53与控制器件30之间电连接安全可靠。
在一实施方式中，参见图8，图8是本申请提供的电子雾化装置的又一实施例的剖视图。壳体50朝向吸嘴组件40的一端设有储液腔12。具体的，壳体50包括侧壁54和隔离壁55，隔离壁55设置于侧壁54围设形成的腔室内，且将腔室分隔形成安装腔51和收容腔56，收容腔56靠近吸嘴组件40设置，收容腔56作为储液腔12使用。
在另一实施方式中，参见图2和图9，图9是本申请提供的供液机构与油瓶连接的一实施例的结构示意图。电子雾化装置100还包括液瓶57，液瓶57设置于壳体50上，液瓶57设有储液腔12。具体的，液瓶57设置于收容腔56内，液瓶57 具有存储气溶胶生成基质的储液腔12。具体的，液瓶57包括瓶身571和瓶嘴572，瓶身571设置于收容腔56内，瓶嘴572用于在壳体50与吸嘴组件40连接时，穿过吸嘴组件40与供液腔11连通。本实施例中，液瓶57和壳体50上设置有限位结构，用于将液瓶57固定设置于壳体50上。例如，液瓶57和壳体50的其中一个设置有限位凸起，另一个设置有限位凹槽，在液瓶57设置于收容腔56内时，限位凸起被固定于限位凹槽内，从而将液瓶57固定设置于壳体50上。液瓶57通过限位结构固定于壳体50上，拆卸方便，便于用户自由地向液瓶57注液，实现重复利用，有利于减少用户使用成本。
在一实施方式中，请继续参见图9，供液机构20包括活塞21和驱动件22，活塞21可移动地设置于储液腔12；驱动件22的输出端连接活塞21，且与控制器件30电连接，用于驱动活塞21沿储液腔的侧壁移动，以向供液腔11供液。其中，驱动件22包括为电机221、蠕动泵或压缩泵等动力源。本实施方式中，活塞21组件位于储液腔12内且位于气溶胶生成基质底部，用于在驱动件22的驱动下，推动其上的气溶胶生成基质向供液腔11供液。
本实施方式中，驱动件22包括电机221和推杆222，推杆222的一端与电机221的输出端连接，另一端与活塞21连接，电机221在工作时，通过推杆222驱动活塞21，以将储液腔12内的气溶胶生成基质推入供液腔11内。
请继续参见图5，为优化产品设计，雾化组件10、供液腔11、储液腔12、供液机构20串联排布，在供液机构20工作时，驱动件22控制活塞21朝向供液腔11的方向移动，以将储液腔12内的气溶胶生成基质注入供液腔11内。
本申请提供的电子雾化装置，为供液腔11和储液腔12双液腔设计，控制器件30基于第一感应元件14检测得到的当前压力值P1，与预设压力值P0进行比较，若当前压力值P1与预设压力值P0的差值D1不在预设范围，控制器件30控制供液机构20，以驱动储液腔12内的液体向供液腔11供液，从而保证供液腔11内的压力一直维持在预设压力范围，实现即用即供的供液效果，有效控制对雾化组件10的液体供给，保证均匀供液，且供液腔11和储液腔12双液腔设计，控制器件30基于供液腔内的当前压力值P1与预设压力值P0的差值D1控制供液机构20驱动储液腔12内的液体向供液腔11供液，解决了传统的单液腔容易受外界大气压影响，发生的液体渗漏和供液不均匀的问题。
为了解决传统的电子雾化装置存在液体渗漏、供液不均等问题，本申请还提供一种电子雾化装置的自动供液方法，参见图10，图10是本申请提供的自动供液方法的一实施例的流程示意图。本申请提供一种自动供液方法，包括：
步骤S1：检测供液腔内的当前压力值。
具体的，电子雾化装置包括雾化组件、供液腔、第一感应元件，供液腔内存储有气溶胶生成基质，雾化组件用于在通电条件下雾化供液腔内的气溶胶生成基质以生成气溶胶，第一感应元件用于检测供液腔内的当前压力值P1。
其中，第一感应元件可以为气压传感器或液压传感器，第一感应元件用于检测供液腔内的气压值或液压值。
在一实施方式中，第一感应元件实时检测供液腔内的当前压力值P1，如，在用户使用电子雾化装置过程中和电子雾化装置的闲置阶段，第一感应元件均检测供液腔内的当前压力值P1。
在另一实施方式中，第一感应元件用于在每次雾化过程中，检测供液腔内的当前压力值P1，即，第一感应元件只在用户抽吸电子雾化装置时检测供液腔内的当前 压力值P1。
步骤S2：基于当前压力值与预设压力值的差值控制供液机构工作，以驱动储液腔内的液体向供液腔供液。
具体的，电子雾化装置还包括储液腔、供液机构以及控制器件，储液腔内存储有气溶胶生成基质，供液机构用于驱动储液腔内的气溶胶生成基质向供液腔供液，控制器件电连接供液机构和第一感应元件，控制器件基于第一感应元件检测得到供液腔内的当前压力值P1，与预设压力值P0的差值D1控制供液机构驱动储液腔内的气溶胶生成基质向供液腔供液。具体的，若当前压力值P1小于预设压力值P0，且当前压力值P1与预设压力值P0的差值D1小于预设限值，控制器件控制供液机构工作，以驱动储液腔内的气溶胶生成基质向供液腔供液，从而保证供液腔内气溶胶生成基质能够维持雾化组件正常雾化。
可以理解的，在用户抽吸电子雾化装置时，随着供液腔内气溶胶生成基质被雾化组件雾化消耗，供液腔内压力会减小，当供液腔内的压力减小到一定程度，会导致供液腔内的气溶胶生成基质对雾化组件供液不足，造成雾化组件干烧以及产生有毒有害气体，而本申请中的控制器件可以基于第一感应元件检测得到的当前压力值P1与预设压力值P0的差值D1，控制供液机构驱动储液腔内的气溶胶生成基质向供液腔供液，保证供液腔内的气溶胶生成基质对雾化组件正常供液，实现了电子雾化装置即用即供的供液效果，且供液腔内的压力一直维持在预设压力范围，能够保证供液腔对雾化组件均匀供液的目的。另外，电子雾化装置设置供液腔和储液腔，控制器件基于当前压力值P1与预设压力值P0的差值D1，控制供液机构驱动储液腔内的气溶胶生成基质向供液腔供液，相比于单液腔，供液腔内的气溶胶生成基质含量较少，可以减少气溶胶生成基质通过雾化组件渗漏的情况发生。
其中，步骤S1包括：响应于抽吸触发信号，检测供液腔内的当前压力值；其中抽吸触发信号由用户抽吸电子雾化装置时触发。
具体的，在用户抽吸电子雾化装置时，电子雾化装置内的气流会发生改变，电子雾化装置中还设置有气流感应件，气流感应件可以为频率硅麦或咪头，用于检测电子雾化装置内的气流变化，气流感应件与控制器件电连接，控制器件基于气流感应件检测到电子雾化装置内的气流发生变化，控制第一感应元件检测供液腔内的当前压力值P1。
其中，预设压力值P0可以为用户刚触发抽吸触发信号时，第一感应元件检测供液腔的当前压力值P1作为预设压力值P0。或预设压力值P0为第一感应元件在电子雾化装置闲置阶段，即电子雾化装置雾化前，检测供液腔内的压力值P3作为预设压力值P0。或预设压力值P0为预先设置在控制器件内的数值。或预设压力值P0以实时检测的外界大气压力值P2作为预设压力值P0。
在一具体实施方式中，控制器件通过第一感应元件检测供液腔在雾化前的压力值P3作为预设压力值P0。
在另一具体实施方式中，电子雾化装置还包括第二感应元件，第二感应元件用于检测外界大气压力值P2，控制器件通过第二感应元件检测到外界大气压力值P2作为预设压力值P0。
或在又一具体实施方式中，电子雾化装置内不设置第二感应元件，第一感应元件还用于检测外界大气压力值P2。具体的，在电子雾化装置雾化之前，第一感应元件检测供液腔内的压力值P3和外界大气压力值P2，同时为控制器件输出供液腔内的压力值P3和外界大气压力值P2，或直接为控制器件输出供液腔内的压力值P3和 外界大气压力值P2的压差D2。
具体的，参见图11，图11是本申请提供的自动供液方法的另一实施例的流程示意图。本实施例中，步骤S1之前还包括：
步骤S01：响应于供液腔在雾化前的压力值与预设压力值的压差处于非预设范围，控制供液机构启动，以驱动储液腔内的液体向供液腔供液，或驱动供液腔内的液体向储液腔导液。
具体的，在雾化前，即，电子雾化装置的闲置阶段，控制器件基于检测到的供液腔内的压力值P3，和检测到的外界大气压力值P2进行比较，响应于供液腔在雾化前的压力值P3和外界大气压力值P2的压差D2处于非预设范围，控制供液机构启动。其中，非预设范围可以是压差D2不等于0，或是压差D2比10Pa、20Pa、50Pa大。
具体的，在一情景中，供液腔内的压力值P3小于外界大气压力值P2，此时，控制器件控制供液机构工作，以驱动储液腔内的气溶胶生成基质向供液腔供液，使得供液腔内的压力值P3与外界大气压力值P2的压差D2处于预设范围。
在另一情景中，供液腔内的压力值P3大于外界大气压力值P2，此时，控制器件控制供液机构工作，以驱动供液腔内的气溶胶生成基质向储液腔导液，使得供液腔内的压力值P3与外界大气压力值P2的压差D2处于预设范围。
步骤S02：响应于供液腔在雾化前的压力值与预设压力值的压差处于预设范围，控制所述供液机构关停。
具体的，在供液机构工作以使供液腔内的压力值P3与外界大气压力值P2处于预设范围时，供液腔在雾化前的压力值P3和外界大气压力值P2的压差D2基本平衡，控制器件响应于供液腔在雾化前的压力值P3和外界大气压力值P2的压差D2处于预设范围，控制供液机构关停，此时供液腔内的压力值P3与实际的外界大气压力值P2基本相同。其中，预设范围可以是压差D2等于0，或是压差D2为0-10Pa、0-20Pa或0-50Pa范围内。
需要说明的是，将供液腔内的压力值P3和外界大气压力值P2平衡的步骤处于电子雾化装置闲置阶段，而在电子雾化装置响应于抽吸触发信号后，控制器件只基于当前压力值P1与预设压力值P0的差值D1控制供液机构工作。具体的，控制器件可以基于雾化组件停止工作预设时间，例如，雾化组件停止工作10分钟、20分钟或更长，判断电子雾化装置处于闲置阶段。以避免影响用户正常抽吸。
参见图12，图12是如图10中所示的步骤S2的一实施例的流程示意图。本实施例中，步骤S2包括：
步骤S21：响应于差值达到预设的第一限值，控制供液机构启动，以驱动储液腔内的液体向供液腔供液。
具体的，响应于抽吸触发信号，雾化组件雾化气溶胶生成基质，当雾化组件微孔内的气溶胶生成基质消耗，雾化组件内微孔会产生毛细力，将供液腔内的气溶胶生成基质导流至雾化组件，从而使供液腔内压力发生变化。随着供液腔内气溶胶生成基质被雾化组件雾化消耗，控制器件计算当前压力值P1与预设压力值P0的差值D1，响应于第一感应元件检测到的当前压力值P1与预设压力值P0的差值D1达到预设的第一限值X1，控制器件控制供液机构启动，以驱动储液腔内的气溶胶生成基质向供液腔供液。
其中，第一限值X1可通过实验得到，当前压力值P1与预设压力值P0的差值D1达到第一限值X1以内时，可以保证供液腔内的气溶胶生成基质均匀地向雾化组 件供液。当然，第一限值X1也可以设置为0，即，供液腔内的气溶胶生成基质刚被消耗，储液腔就向供液腔供液，以保持供液腔内的当前压力值始终与预设压力值平衡。
在一实施方式中，第一限值X1的取值范围为-100Pa-(-200Pa)，即当前压力值P1小于预设压力值P0，且当前压力值P1与预设压力值P0的差值D1为100Pa-200Pa。例如，在当前压力值P1小于预设压力值P0，且当前压力值P1与预设压力值P0的差值D1达到150Pa时，控制器件控制供液机构启动，以驱动储液腔内的气溶胶生成基质向供液腔供液。
步骤S22：响应于差值达到预设的第二限值，控制供液机构关停，以停止驱动储液腔内的液体向供液腔供液。
具体的，随着供液机构驱动储液腔内的气溶胶生成基质向供液腔供液，控制器件计算当前压力值P1与预设压力值P0的差值D1，响应于第一感应元件检测到的当前压力值P1与预设压力值P0的差值D1达到预设的第二限值X2，控制器件控制供液机构关停，以停止驱动储液腔内的气溶胶生成基质向供液腔供液。
其中，第二限值X2大于第一限值X1，第二限值X2可通过实验得到，在当前压力值P1与预设压力值P0的差值D1达到第二限值X2以内时，可以保证供液腔内的气溶胶生成基质均匀地向雾化组件供液，且不会由于供液腔内的压力过大，导致供液腔内气溶胶生成基质发生渗漏的问题产生。
在一实施方式中，第二限值X2的取值范围为250Pa-350Pa，即当前压力值P1大于预设压力值P0，且当前压力值P1与预设压力值P0的差值D1为250Pa-350Pa。例如，在当前压力值P1大于预设压力值P0，且当前压力值P1与预设压力值P0的差值D1达到300Pa时，控制器件控制供液机构关停，以停止驱动储液腔内的气溶胶生成基质向供液腔供液。
当然，第二限值X2也可以设置为0，即，只要供液腔内的当前压力值P1等于预设压力值P0，储液腔就停止向供液腔供液，以保持供液腔内的当前压力值始终与预设压力值平衡。
需要说明的是，用户抽吸一口电子雾化装置的时间一般维持3-5s左右，一次供液可能维持或不能维持用户抽吸一口时雾化所需的气溶胶生成基质量，因此，在一次抽吸触发信号中，控制器件可能控制供液机构驱动储液腔内的气溶胶生成基质向供液腔供液N次，即差值D1达到第一限值X1的次数为N次，相应的，控制器件可能控制供液机构停止驱动储液腔内的气溶胶生成基质向供液腔供液M次，即差值D1达到第二限值X2的次数为M次，从而保证供液腔内的溶胶生成基质含量能够维持用户抽吸。如图13所示，图13是本申请提供的供液时供液腔内当前压力值与预设压力值的差值的一实施例的曲线示意图，其中，横坐标代表时间，纵坐标代表供液腔内当前压力值P1与预设压力值P0的差值D1。如图13所示，一次抽吸触发信号T中，会出现多个上尖峰和下尖峰，也就是说，在一次抽吸触发信号T中，可能储液腔内的气溶胶生成基质刚供液给供液腔，供液腔内的气溶胶生成基质随之就被消耗，从而需要储液腔多次向供液腔供液，以使供液腔内的当前压力值P1始终高于压力下限值。
在又一实施例中，步骤S2包括：响应于差值D1达到预设的第一限值X1，控制供液机构启动，并保持供液机构运行预设时长。
具体的，控制器件计算当前压力值P1与预设压力值P0的差值D1，响应于第一感应元件检测到的当前压力值P1与预设压力值P0的差值D1达到预设的第一限值 X1，控制器件控制供液机构启动，且控制供液机构运行预设时长，以在预设时长内驱动储液腔内的气溶胶生成基质向供液腔供液。在供液机构运行预设时长后，控制器件控制供液机构关停，以停止驱动储液腔内的气溶胶生成基质向供液腔供液。
其中，预设时长可通过实验得到，当供液腔内的当前压力值P1与预设压力值P0的差值D1达到第一限值X1，控制器件控制供液机构运行预设时长后，使得供液腔内的当前压力值P1大于或等于预设压力值P0，且供液腔内的当前压力值P1与预设压力值P0的差值D1处于0至第二限值X2范围。例如，第一限值X1为-100Pa，第二限值X2为300Pa，控制器件基于第一感应元件检测得到的供液腔内的当前压力值P1小于预设压力值P0，且当前压力值P1与预设压力值P0的差值D1为100Pa时，控制器件控制供液机构运行预设时长，在供液机构运行预设时长后，控制器件控制供液机构关停，此时供液腔内的当前压力值P1大于或等于预设压力值P0，如，当前压力值P1与预设压力值P0的差值D1为0Pa-300Pa范围内，但不超过300Pa。
其中，控制器件30可以为控制线路板或计算机设备，参见图14，图14是本申请提供的计算机设备的一实施例的模块示意图。计算机设备包括相互连接的处理器301和存储器302。
存储器302存储有计算机程序。
