本发明提供了一种电子烟，该电子烟内设置有储液组件和微流供液组件，其中：储液组件用于存储至少一种液体，这里所讲的至少一种液体可以全部为烟液，也可以为不同的烟液组分，这里所讲的烟液组分包括基础烟液，还可以 包括尼古丁、香精香料中至少一种。在实际实现时，烟液组分还可以为烟液中其他本申请未示出的液体，本申请对此不再一一赘述，其中，本实施方式中，基础烟液的主要成分为丙二醇、丙三醇，可以理解的，在其它实施方式中，基础烟液可以为其它成分并不做限定；储液组件中存储的至少一种烟液组分混合后能够形成烟液。在其中一个实施方式中，储液组件包括至少一个储液件，一个储液件内存储一种液体。
其中，微流供液组件包括至少一个微通道和至少一个微型泵，每个微通道的进液口与一个微型泵的出液口相连通且该微型泵的进液口与一个储液件相连通。

以电子烟内储液组件用于存储烟液组分再进行举例说明。储液组件内包括多个储液件，例如，包括两个或两个以上储液件，每个储液件用于存储不同的烟液组分，不同储液件内液体可通过不同的微型泵输送至不同的微通道。例如，储液组件内包括3个储液件，分别用于存储尼古丁、基础烟液、香精香料，尼古丁的存储件由微型泵A1从中抽取尼古丁输送至微通道A2，基础烟液的存储件由微型泵B1从中抽取基础烟液输送至微通道B2，香精香料的存储件由微型泵C1从中抽取尼古丁输送至微通道C2。
可选的，每个储液件与微通道的进液口之间设置有气液分离装置，该气液分离装置过滤液体中的气体，过滤后的液体被输送至微通道。可选的，该气液分离装置的出液口与微通道的进液口之间设置有电磁阀，通过控制该电磁阀的开关可控制是否向微通道供液。例如，气液分离装置设置在微型泵与电磁阀之间。可选的，电子烟在需要将某一储液件内液体提供给雾化腔时，可同时打开 该储液件与微通道之间的微型泵以及电磁阀；在需要停止将该储液件内液体提供给雾化腔时，可同时关闭该储液件与微通道之间的微型泵以及电磁阀。

请参考图6，方式A中，电子烟内可仅设置有一个雾化腔，电子烟内储液组件用于存储烟液，电子烟利用微型泵抽取烟液至一个微通道，烟液通过该微通道流向雾化腔，该雾化腔内雾化组件工作以雾化烟液；方式B中，电子烟内可仅设置有一个雾化腔，电子烟内储液组件用于存储烟液，电子烟利用微型泵抽取烟液至多个微通道，烟液通过该多个微通道流向雾化腔，该雾化腔内雾化组件工作以雾化烟液；方式C中，电子烟内设置有多个雾化腔、多个微通道、多个微型泵以及多个储液件，电子烟内雾化腔、微通道、微型泵以及储液件的 设置数量相同(例如为a)且一一对应，则电子烟内形成a个烟液输送路径，每个微型泵抽取烟液组分输送至对应的微通道，各个微通道将不同的烟液组分输送至不同雾化腔分开雾化；方式D中，电子烟内设置有多个雾化腔、多个微通道、多个微型泵以及多个储液件，电子烟内雾化腔、微通道、微型泵以及储液件的设置数量相同(例如为a)且一一对应，则电子烟内形成a个烟液输送路径，每个微型泵抽取烟液组分输送至对应的微通道，各个微通道将不同的烟液组分输送至同一雾化腔进行混合，混合物在该雾化腔内雾化。
请参考图1，其示出了本发明一个实施例提供的供液方法的方法流程图，本实施例以该供液方法用于电子烟中来举例说明。如图1所示，该供液方法可以包括：
步骤110，获取电子烟的工作参数，该工作参数包括雾化器的输出功率、雾化腔内温度、电子烟的输出电压中至少一种。
可选的，在检测到点烟信号时，执行如图1所示的几个步骤。
步骤120，根据该工作参数确定电子烟内至少一种液体的消耗速度，该至少一种液体均为烟液或者均为烟液组分。
本步骤可通过以下几种方式实现：
第一种，电子烟内的储液组件用于存储烟液，烟液雾化后产生的气溶胶供用户抽吸，则本步骤的实现可以为：根据电子烟的工作参数确定烟液的消耗速度。具体的，电子烟内可存储有工作参数、烟液的消耗速度之间的对应关系，该对应关系可以以数据的等形式存储在电子烟内，例如图表、代码等并不做限定；电子烟可获取电子烟当前的工作参数，查询该工作参数对应的烟液消耗速度。
第二种，根据雾化器的输出功率或输出电压确定电子烟的热量产生速度；根据该热量产生速度确定每种液体的消耗速度。
在一个示例中，电子烟内的储液组件用于存储烟液，烟液雾化后产生的气溶胶供用户抽吸，则电子烟可根据雾化器的输出功率或输出电压确定电子烟的热量产生速度；根据该热量产生速度确定烟液的消耗速度。例如，根据雾化器的输出功率确定电子烟在单位时间内产生的热量；确定该热量所能够雾化的烟液的体积得到烟液的消耗速度。
在另一个示例中，电子烟内的储液组件用于存储烟液组分，雾化过程中电子烟将不同烟液组分通过不同微通道输送至同一雾化腔，则电子烟可根据雾化器的输出功率或输出电压确定电子烟的热量产生速度；根据该热量产生速度、该至少一种液体的雾化比例，确定每个微通道所输送的液体的消耗速度。
具体的，根据雾化器的输出功率或输出电压确定电子烟在单位时间内产生的热量；确定该热量所能够雾化的烟液的体积；根据该至少一种液体的雾化比例、与该烟液的体积确定每种液体的消耗速度。其中，该至少一种液体的该雾化比例为电子烟使用过程中各个液体的消耗比例，该至少一种液体的雾化比例可以为该至少一种液体混合能够形成烟液时的混合比例，该雾化比例可以由系统开发人员设定，也可由用户根据自身抽吸口感需要自定义，还可以为电子烟根据用户设定的抽吸口感确定的。例如，电子烟用户喜欢烟味淡一点的，则基础烟油的雾化比例可以大一点，尼古丁的雾化比例可以小一点。
举例来讲，若电子烟在单位时间内产生的热量所能够雾化的烟液的体积为A，储液组件内基础烟液、香料香精、尼古丁的混合比例为x：y：z，则基础烟液在单位时间内消耗的体积为

香料香精在单位时间内消耗的体积为
Figure PCTCN2020108146-appb-000002
尼古丁在单位时间内消耗的体积为
Figure PCTCN2020108146-appb-000003
第三种，电子烟内的储液组件用于存储烟液组分，雾化过程中电子烟将不同烟液组分通过不同微通道输送至多个雾化腔分开雾化，则本步骤的实现可以为：根据雾化器的输出功率或输出电压、该至少一种液体的雾化比例、被输送至每个雾化腔的液体类型，确定每个雾化腔内雾化组件的输出功率或输出电压；根据每个雾化腔内雾化组件的输出功率或输出电压确定被输送至该雾化腔的液体的消耗速度。其中，需要说明的一点是，该方式中每个雾化腔仅用于雾化一种烟液组分，且单位输出功率或单位输出电压对应的液体的消耗速度是已知的，可以理解的，单位输出功率或单位输出电压对应的液体的消耗速度是指每输出1W的功率所对应的液体消耗速度，消耗速度为毫升/秒，单位输出功率或单位输出电压对应的液体的消耗速度可存储在电子烟中，在根据每个雾化腔内雾化组件的输出功率或输出电压确定被输送至该雾化腔的液体的消耗速度时，根据雾化腔内雾化组件的输出功率与单位输出功率对应的液体的消耗速度计算液体的消耗速度，根据雾化腔内雾化组件的输出电压与单位输出电压对应的液体的消耗速度计算液体的消耗速度。其中，单位输出功率或单位输出电压对应的液 体的消耗速度可以是系统开发人员设定的，例如系统开发人员可进行多次试验确定。
步骤130，根据每种液体的消耗速度，控制微流供液组件利用微通道将每种液体供液给雾化组件进行雾化。
本步骤可通过以下几种方式实现：
第一种，每个微通道内设置有微型阀，根据每种液体的消耗速度控制用于输送该液体对应微通道内微型阀的开口程度，以及将每种液体通过对应微通道供液给雾化组件进行雾化。在实际实现时，所有该微通道的出液口可与同一雾化腔相连通，或者，各个微通道的出液口与唯一对应的一个雾化腔相连通。
在实际实现时，一种液体可通过一条或多条微通道输送至雾化腔。在一种液体仅通过一条微通道输送至雾化腔时，通过控制该微通道内微型阀使通道内液体流速等于或接近该液体的消耗速度；在一种液体通过多条微通道输送至雾化腔时，通过控制其中的每个微通道内的微型阀使该多条通道内液体流速总和等于或接近该液体的消耗速度。
可选的，每条微通道内还可设置有微流量传感器，获取每个微通道内微流量传感器检测到的流速值；根据每个微通道的流速值与该微通道所输送的液体的消耗速度，调整内部微型阀的开口程度。其中，微流量传感器是对微流体的精确测量，其依据工作原理可分为热式(包括热传导式和热飞行时间式)、机械式和谐振式三种，本实施例不对微流量传感器的选型做具体限定。
具体实现可以为：在一种液体仅通过一条微通道输送至雾化腔时，根据该微通道的流速值与该微通道所输送的液体的消耗速度的大小关系，调整内部微型阀的开口程度；在一种液体对应多条微通道时，根据该多条通道内液体流速总和、该液体对应的消耗速度之间的大小关系，调整该多个微通道内微型阀的开口程度。
第二种，根据每种液体的消耗速度确定每种液体的注入频率和单次注入量，按照每种液体的注入频率和单次注入量进行供液的供液速度等于其消耗速度；对于每种液体按照每种液体的注入频率，每次向该液体对应的微通道的进液口注入对应单次注入量的液体；每次向每个微通道注入对应单次注入量的液体后注入分隔物；其中，该分隔物为气体或者该分隔物为液体，该液体为烟液组分。在实际实现时，所有该微通道的出液口可与同一雾化腔相连通，或者，各个微 通道的出液口与唯一对应的一个雾化腔相连通。
可选的，该分隔物可以为固定体积的气体团，电子烟内设置有抽气泵，该抽气泵可从外界抽吸空气至气固分离装置以过滤空气中的固体杂质，以提高电子烟雾化的气溶胶的抽吸口感；过滤后的气体可通过气流通道流向各个微通道的进液口，气固分离装置的出气口与每个微通道的进液口间的气流通道中设置有电磁阀，通过控制该电磁阀的开关以控制注入该微通道的气体量。
在分隔物为固定体积的气体团时，气体团将微通道内液体分隔开；也就是说，向微通道内输入液体后可再注入气体团，气体团注入完毕后再注入液体，如此循环往复。举例来讲，连接在微通道、储液件之间电磁阀打开且气流通道内电磁阀关闭0.5秒后，连接在微通道、储液件之间电磁阀关闭且气流通道内电磁阀打开0.2秒，连接在微通道、储液件之间电磁阀打开且气流通道内电磁阀关闭再0.5秒，连接在微通道、储液件之间电磁阀关闭且气流通道内电磁阀打开再0.2秒，如此循环。
在实际实现时，分隔物采用液体时分隔物也会被雾化组件雾化，消耗电子烟产生的热量，容易造成热量的浪费。可选的，分隔物可采用基础烟油，以避免电子烟内产生的热量浪费。
可选的，该分隔物可以为烟液组分，对于每个微通道，控制该微通道所输送的液体的注入速度不同于分隔物的注入速度，使得该微通道中部分液体与分隔物混合；对于每个微通道，控制该微通道中未被分隔物污染的液体(也即，未与分隔物混合的部分液体)流向用于存储该液体的储液件。
以分隔物为基础烟液来进行举例说明，尼古丁和香精香料的注入速度与基础烟液的注入速度不同，导致一个微通道内尼古丁的流速与基础烟液的流速不同，另一微通道内香精香料的流速与基础烟液的流速不同，使得基础烟液被注入微通道后冲击尼古丁或者香精香料，微通道内一次性注入的基础烟液部分与尼古丁或者香精香料混合。
第三种，在导流件上开设一个与储液组件连通的槽，所述槽作为微通道，每个该微通道的出液口设置有微型阀，根据每种液体的消耗速度、该槽的容积确定每种液体的供液频率，例如计算每种液体的消耗速度与该槽的容积的商值得到每种液体的供液频率；按照每个槽的供液频率，每次先关闭该槽的出口处的微型阀，向该槽注满对应液体以及给该槽内液体上电(正电荷或负电荷)， 打开该微型阀；其中，每个槽的出口处的微型阀打开后，该槽内液体被电荷间力运输至雾化组件处。在实际实现时，所有该微通道的出液口可与同一雾化腔相连通，或者，各个微通道的出液口与唯一对应的一个雾化腔相连通。
在实际实现时，电子烟内多个微通道可开设于同一导流件上，也可开设于不同导流件上。

在另一个示例中，每个微通道的进液口均能够通过对应的微型泵与一个储液件相连通，该微通道上开设有多个透气孔，该微通道通过该透气孔与烟嘴连通，该微通道为该雾化组件的加热件，微通道发热时雾化出的气溶胶通过至少一个该透气孔溢出该微通道但微通道内任何液体(包括烟液组分、分隔物中、烟液)难以从透气孔中溢出，例如该透气孔的孔径可以为毫米级别的。
