具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本申请的一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
以下描述中，为了说明而不是为了限定，提出了诸如特定系统结构、接口、技术之类的具体细节，以便透彻理解本申请。
本申请中的术语“第一”、“第二”、“第三”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”、“第三”的特征可以明示或者隐含地包括至少一个所述特征。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。本申请实施例中所有方向性指示(诸如上、下、左、右、前、后……)仅用于解释在某一特定姿态(如附图所示)下各部件之间的相对位置关系、运动情况等，如果所述特定姿态发生改变时，则所述方向性指示也相应地随之改变。本申请实施例中的术语“包括”和“具有”以及它们任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或组件。
在本文中提及“实施例”意味着，结合实施例描述的特定特征、结构或特性可以包含在本申请的至少一个实施例中。在说明书中的各个位置出现所述短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是，本文所描述的实施例可以与其它实施例相结合。
本申请发明人研究发现在换气过程中，虽然两个子储液腔分别设有独立的换气通道，而气体一旦开通从一侧换气通道换气后，就习惯于从这一侧换气通道换气，另一侧基本不会换气，并且在另一侧下液的时候，依然是这一侧换气通道换气，气泡会从发热体靠近储液腔的表面去到另一侧通道，增大了气泡附着在发热体靠近储液腔表面的概率，因此，易导致供液不足，造成干烧。为此，本申请提供一种具有新的换气结构的雾化器1及电子雾化装置100。
下面结合附图和实施例对本申请进行详细的说明。
请参阅图1，图1是本申请实施例提供的电子雾化装置的结构示意。

其中，雾化器1用于存储气溶胶生成基质并雾化气溶胶生成基质以形成可供用户吸食的气溶胶。该雾化器1具体可用于不同的领域，比如，医疗、美容、休闲吸食等。在一具体实施例中，该雾化器1可用于电子气溶胶化装置，用于雾化气溶胶生成基质并产生气溶胶，以供抽吸者抽吸，以下实施例均以此休闲吸食为例。
雾化器1的具体结构与功能可参见以下实施例所涉及的雾化器1的具体结构与功能，且可实现相同或相似的技术效果，在此不再赘述。

雾化器1与主机2可以是一体设置，也可以是可拆卸连接，可以根据具体需要进行设计。
请参阅图2，图2是图1提供的电子雾化装置的雾化器一实施例的结构示意图。
雾化器1包括壳体11、雾化座12和发热体13。壳体11的一端为敞口端，雾化座12设于壳体11内且封堵该敞口端，雾化座12与壳体11配合形成储液腔10，储液腔10用于存储气溶胶生成基质。雾化座12包括顶座121和底座122，底座122将壳体11的敞口端封堵，即壳体11与顶座121配合形成储液腔10；顶座121和底座122配合形成安装腔(图未标)，安装腔用于安装发热体13。即，发热体13设于安装腔内，发热体13同雾化座12一起设于壳体11内。顶座121上设有下液孔1211，发热体13通过下液孔1211与储液腔10流体连通，发热体13用于雾化气溶胶生成基质生成气溶胶。
发热体13与安装腔的底壁之间间隔设置形成雾化腔120，即发热体13远离储液腔10的表面与安装腔的腔壁配合形成雾化腔120；发热体13雾化产生的气溶胶释放于雾化腔120内。壳体11具有出雾通道111，顶座121上设有出雾孔1210，出雾孔1210将雾化腔120与 出雾通道111连通。底座122上设有进气通道1221，进气通道1221将外界气体与雾化腔120连通。外界气体通过进气通道1221进入雾化腔120内，携带雾化腔120内的气溶胶经出雾孔1210流至出雾通道111，用户通过出雾通道111的端口吸食气溶胶。
可以理解，在本实施例中，雾化座12由顶座121和底座122上下装配形成；在其他实施例中，雾化座12也可以由两个结构件左右装配形成，具体根据需要进行设计。也就是说，本申请并不限定雾化座12的结构，仅以顶座121和底座122形成的雾化座12为例进行详细介绍。
请参阅图3和图4，图3是图2提供的雾化器的壳体的仰视结构示意图，图4是图2提供的雾化器另一角度的结构示意图。
在本实施例中，壳体11的内部具有隔片112，隔片112的长度方向与雾化器1的轴向方向相同，隔片112将储液腔10分隔为两个子储液腔101；具体地，壳体11具有两个隔片112，两个隔片112分别设置于出雾通道111的相对两侧，隔片112的一侧与出雾通道111的外表面连接，隔片112的另一侧与壳体11的内表面连接，隔片112将壳体11与顶座121围设形成的空间分隔成相互独立的两个子储液腔101。顶座121上设有两个下液孔1211，一个下液孔1211与一个子储液腔101连通，另一个下液孔1211与另一个子储液腔101连通；即，两个下液孔1211与两个子储液腔101一一对应连通。可选的，隔片112与壳体11一体成型。
本实施例中，两个隔片112共面设置且两个隔片112所在的平面垂直于雾化器1的宽度方向。在其他实施例中，也可以不设置隔片112，将壳体11的内表面与出雾通道111的外表面相切并连接，从而将壳体11与顶座121围设形成的空间分隔成相互独立的两个子储液腔101。
雾化器1还包括密封件14，密封件14套设于顶座121的表面，用于防止漏液。密封件14设于顶座121的顶面和侧面，隔片112与密封件14位于顶座121的顶面的部分抵接，以将两个子储液腔101完全分隔开来，即，两个子储液腔101为相互独立的空腔。可以理解，当顶座121上并未设置用于密封的密封件14时，隔片112与顶座121抵接，以将两个子储液腔101完全分隔开来。密封件14位于顶座121的顶面的部分设有贯穿孔(图未标)，贯穿孔对应于顶座121上的下液孔1211和出雾孔1210设置，以使下液孔1211和出雾孔1210露出，实现下液孔1211与储液腔10连通，出雾孔1210与出雾通道111连通。
发热体13与顶座121配合形成发热体吸液腔130，发热体吸液腔130分别与两个下液孔1211连通。具体地，顶座121靠近底座122的一端具有台阶槽(图未标)，台阶槽包括 靠近下液孔1211的第一凹槽(图未标)和远离下液孔1211的第二凹槽(图未标)；第二凹槽的尺寸大于第一凹槽的尺寸；发热体13设置于第二凹槽内并覆盖第一凹槽，发热体13与第一凹槽配合形成发热体吸液腔130。
两个子储液腔101、两个下液孔1211以及发热体吸液腔130形成U型结构(如图5所示，图5是图2提供的雾化器的储液腔结构的简易示意图)。具体地，两个子储液腔101分别为第一子储液腔101、第二子储液腔101；两个下液孔1211分别为第一下液孔1211和第二下液孔1211，第一子储液腔101、第一下液孔1211、发热体吸液腔130、第二下液孔1211以及第二子储液腔101依次连接形成U形结构；雾化器1倒置时，两个子储液腔101内的气体和/或气溶胶生成基质不串流。
通过上述设置，雾化器1在倾斜或翻转的过程中，两个子储液腔101内的气体无法突破下液孔1211靠近储液腔10的端口的表面张力，无法实现两个子储液腔101之间的气体流通。由于两个子储液腔101之间无法实现气体流通，两个子储液腔101内的气溶胶生成基质和气体只能在各自区域内进行流动，而其整体若要向某一侧流动，则必然受到两侧气体的阻力，因此在下液孔1211靠近储液腔10的端口的表面张力和两个子储液腔101内气体压力的作用下，发热体吸液腔130内的气溶胶生成基质只能滞留在发热体吸液腔130内，以及下液孔1211内的气溶胶生成基质只能滞留在下液孔1211内，从而达到实现倾斜和倒置后在发热体吸液腔130和下液孔1211内储液的效果，保证倒抽时的供液充足，短时间内不会出现发热体13烧焦或烧断的现象。
继续参见图2，在本实施例中，发热体13为片状，发热体13包括导液基体(图未标)和发热元件(图未标)，发热元件设于导液基体的表面，导液基体用于导引气溶胶生成基质，发热元件用于雾化气溶胶生成基质。导液基体的材料可以为多孔陶瓷，也可以为致密材料；当导液基体的材料为致密材料，可以为石英、玻璃、致密陶瓷或硅。在其他实施例中，发热体13可以为现有的多孔陶瓷发热体或棉芯发热体，具体根据需要进行设计。
申请人研究发现，U型的储液结构中两个子储液腔101的两侧下液并不同步，通常是一侧的液面低至下液孔1211的底端，另一侧才开始下液；其原因主要为雾化器1设有两个独立的换气结构，一个换气结构对应一个子储液腔101设置，另一个换气结构对应另一个子储液腔101设置，以上述的两个换气结构进行换气时，气体一旦开通从一侧换气结构换气后，就习惯于从这一侧换气结构换气，另一侧基本不会换气，并且在另一侧下液的时候，依然是这一侧换气结构换气，气泡会从发热体13靠近储液腔10的表面去到另一侧通道，增大了气泡附着在发热体靠近储液腔表面的概率，易导致供液不足。另外，申请人研究还发现，若两 个子储液腔101中的一个液体为满的，一个有气泡的情况下，将雾化器1倒置(发热体13位于储液腔10的上方)的过程中，U型结构无法发挥储液功能，气泡会缓缓进入发热体13靠近储液腔10的表面，导致发热体13靠近储液腔10的表面的部分没有气溶胶生成基质或气溶胶生成基质不足，出现干烧。对于上述问题，本申请对换气结构进行了改进，详见下述内容。
请参阅图6和图7，图6是图2提供的雾化器的顶座的结构示意图，图7是图6提供的顶座的局部放大结构示意图。
图4结合图6，顶座121上设有相互连通的换气槽1212和导气槽1213，导气槽1213与外界气体或雾化腔120连通；其中，换气槽1212位于两个子储液腔101的相邻处，且分别与两个子储液腔101连通。
外界气体通过导气槽1213和换气槽1212进入子储液腔101，实现对子储液腔101的换气，平衡气压，保证供液充足。由于雾化腔120通过进气通道1221与外界气体连通，导气槽1213与雾化腔120连通也可以实现对子储液腔101的换气。换气槽1212与两个子储液腔101均直接连通(如图4所示)，以使换气气泡可以较为随机的进入两个子储液腔101中，保证两侧均能够进行换气，而不是仅有单侧能够进行换气，使得两侧均能够下液，保证供液充足。
具体地，换气槽1212和导气槽1213均设置于顶座121的侧面，换气槽1212设于导气槽1213靠近储液腔10的一侧。换气槽1212沿雾化器1的轴向方向延伸，换气槽1212为导气槽1213靠近储液腔10一侧的凹槽。导气槽1213包括多个间隔设置且沿雾化器1的周向延伸的子导气槽1213a，多个子导气槽1213a之间相互连通或依次连通。换气槽1212通过导气槽1213的侧壁上的开口(图未标)与导气槽1213连通。
在本实施例中，密封件14设于顶座121的表面和侧面，密封件14位于顶座121的侧面的部分盖设于换气槽1212和导气槽1213的开口，即，密封件14与换气槽1212配合形成换气孔(图未标)，密封件14与导气槽1213配合形成换气通道(图未标)，换气孔和换气通道组合形成雾化器1的换气结构。由于换气槽1212与导气槽1213相互连通，密封件14与换气槽1212、导气槽1213配合形成的换气孔和换气通道相互连通；导气槽1213与外界气体或雾化腔120连通，密封件14和导气槽1213配合形成的换气通道与外界气体或雾化腔120连通。
在其他实施例中，也可以是仅在密封件14的内表面设置换气槽1212和导气槽1213，或在密封件14的内表面和顶座121的外表面均设置换气槽1212和导气槽1213，密封件14 与顶座121配合形成相互连通的换气孔或换气通道，换气孔或换气通道组合形成雾化器1的换气结构。
可选的，换气槽1212的宽度W1大于0.2mm，以使其具有足够的宽度能够与两个子储液腔101分别连通。
可选的，换气槽1212的宽度W1大于导气槽1213的宽度W2；和/或，换气槽1212的深度大于等于导气槽1213的深度，以使与两个子储液腔101直接连通的换气槽1212形成相对于导气槽1213的开阔空间，实现对换气气泡的缓速，缓速的气泡可以较为随机的进入两个子储液腔101中，保证两侧均能够进行换气，而不是仅有单侧能够进行换气，使得两侧均能够下液，保证供液充足。在一实施方式中，换气槽1212的宽度W1为4倍-10倍导气槽1213的宽度W2，以形成相对于导气槽1213的开阔空间。
可选的，换气槽1212的长度H1为0.3mm-2mm，与换气槽1212的宽度W1配合，以形成相对于导气槽1213的开阔空间。
换气槽1212设于隔片112在顶座121上的投影处，以使换气槽1212位于两个子储液腔101的相邻处；隔片112的两侧均有部分换气槽1212暴露，以使换气槽1212分别与两个子储液腔101直接连通。具体地，顶座121上设有两个对称的换气槽1212，两个换气槽1212与两个隔片112一一对应设置；即，一个隔片112在顶座121上的投影处设有一个换气槽1212。
由于隔片112与密封件14抵接，隔片112位于换气槽1212的上方，隔片112会对进入换气槽1212的换气气泡起到阻挡作用，以对换气气泡进行缓速或卡在换气槽1212内，利用气泡随机流动的特性，卡住或缓速的气泡随机进入两个子储液腔101，实现对两个子储液腔101的随机换气。其中，换气槽1212形成的开阔空间与隔片112配合形成的腔体可以有效的对换气气泡进行缓速。
在本实施例中，换气槽1212为沿雾化器1轴向延伸的凹槽，隔片112垂直于换气槽1212的宽度方向设置。隔片112在顶座121上的投影将换气槽1212分割为两个子换气槽1212a。一个子换气槽1212a对应于一个子储液腔101，对该子储液腔101进行换气；另一个子换气槽1212a对应于另一个子储液腔101，对该子储液腔101进行换气。可选的，隔片112在顶座121上的投影将换气槽1212等分为两个子换气槽1212a。
需要说明的是，在电子雾化装置加热雾化的开始阶段，若出现气泡只往两个子储液腔101中一侧运动的情况，在抽吸几口后，气泡会卡在换气这一侧对应的子换气槽1212a中(即卡泡)，从而使得换气气泡向另一侧运动，继续抽吸一段时间后，气泡也会卡在另一侧对应 的子换气槽1212a中，此时，两个子换气槽1212a均卡泡，随着换气的需要，换气气泡随机突破两个子换气槽1212a中的任意一个，整体呈现出“伪随机”状态，实现两侧换气的目的。在雾化器1倒置(发热体13位于储液腔10上方)，换气槽1212处于液封状态，不会影响上述所述的U型结构的锁液功能。
可选的，子换气槽1212a的宽度为2倍-5倍导气槽1213的宽度W2。是为了形成相对于导气槽1213的开阔空间，以对气泡进行缓速，避免一直单侧换气。
参阅图7，换气槽1212包括第一槽段1212b和第二槽段1212c，第一槽段1212b位于第二槽段1212c靠近储液腔10的一侧，第一槽段1212b的宽度大于第二槽段1212c的宽度。进一步，在换气槽1212的中间位置设有分隔柱1214，分隔柱1214将换气槽1212分割为两个子换气槽1212a，一个子换气槽1212a与一个子储液腔101连通，另一个子换气槽1212a与另一个子储液腔101连通，即两个所述子换气槽与两个所述子储液腔一一对应连通。可选的，分隔柱1214将换气槽1212等分为两个子换气槽1212a。通过设置分隔柱1214，除了能对气泡起到阻挡作用，还可以起到分割气泡的作用，随机卡泡，避免一直单侧换气。
可选的，子换气槽1212a的宽度大于导气槽1213的宽度。
可选的，分隔柱1214设于第二槽段1212c，换气槽1212具有一个换气口1212d，将换气槽1212与储液腔10连通的端口定义为换气口1212d；一个换气口1212d分别与两个子储液腔101连通(如图7所示)。
可选的，隔片112在顶座121上的投影与分隔柱1214重合，以增大子换气槽1212a的暴露面积，更好的换气。
可选的，分隔柱1214的高度小于等于换气槽1212的深度。其中，分隔柱1214设于换气槽1212的底壁，分隔柱1214的高度为分隔柱1214远离换气槽1212的底壁的端面与换气槽1212的底壁之间的距离。由于换气槽1212与密封件14配合形成换气孔，分隔柱1214的高度小于等于换气槽1212的深度，便于密封件14的装配且利于实现较好的密封效果。
可以理解，换气槽1212的中间位置是否设置分隔柱1214，均可以通过换气槽1212形成的开阔空间与隔片112配合形成的腔体有效的对换气气泡进行缓速，随机卡泡，避免一直单侧换气；而在换气槽1212的中间位置设置分隔柱1214，进一步对换气气泡进行缓速，且可以分割气泡，能够更好的避免单侧换气。分隔柱1214为可选结构，根据需要进行设计。
继续参见图4和图7，顶座121的顶部对应于换气槽1212设有凸起1215，凸起1215沿着换气槽1212的周缘设置。密封件14位于顶座121的顶面的部分设有通孔(图未标)，凸起1215嵌设于通孔内，以对密封件14进行限位，使得密封件14装配于顶座121上后， 换气槽1212总是暴露于储液腔10的，保证换气的顺利进行。可以理解，也可以顶座121的顶部对应于换气槽1212设有卡槽，即，将凸起1215对应位置设置卡槽，在密封件14上设置与卡槽对应的凸块，从而实现卡接限位。
请参阅图8，图8是图2提供的雾化器的密封件与雾化座的装配结构示意图。
进一步，密封件14覆盖雾化座12的顶面部分的厚度大于凸起1215的高度。当凸起1215嵌设于密封件14的通孔内时，凸起1215靠近储液腔10的端面低于密封件14靠近储液腔10的表面。密封件14的材料为硅胶，雾化座12(即顶座121和底座122)的材料为塑胶，相对于塑胶，硅胶与气溶胶生成基质的接触角相对于塑胶与气溶胶生成基质的接触角更大，将密封件14的厚度设置为大于凸起1215的高度，密封件14更容易粘气泡，进而更容易卡气泡，避免一直单侧换气，整体呈现出随机换气状态。
请参阅图9，图9是图2提供的雾化器的储液腔另一结构的简易示意图。
在该实施方式中，储液腔10包括两个子储液腔101和连通储液腔103，连通储液腔103将两个子储液腔101连通。将储液腔10分隔为两个子储液腔101的隔片112靠近顶座121的端面与顶座121间隔设置，隔片112的两侧分别为子储液腔101，隔片112靠近顶座121的一端与顶座121之间形成连通储液腔103。
申请人研究发现，对于该储液结构，雾化器1设有两个独立的换气结构，一个换气结构对应一个子储液腔101设置，另一个换气结构对应另一个子储液腔101设置，以上述的两个换气结构进行换气时，气体一旦开通从一侧换气结构换气后，就习惯于从这一侧换气结构换气，另一侧基本不会换气，并且在另一侧下液的时候，依然是这一侧换气结构换气，气泡会从发热体13靠近储液腔10的表面去到另一侧通道，增大了气泡附着在发热体靠近储液腔表面的概率，易导致供液不足。即，对于该储液结构也是存在一直单侧换气的问题，通过在顶座121上设置上述详细介绍的换气槽1212和导气槽1213，可以避免一直单侧换气；优选，换气槽1212的中间位置设有分隔柱1214。
需要说明的是，由于单侧换气导致的两侧液面不相同的情况，均可以通过在两侧子储液腔101的相邻处设置上述介绍的换气槽1212来解决一直单侧换气的问题，以使两侧液面均衡。
请参阅图10，图10是图1提供的电子雾化装置的雾化器另一实施例中顶座的局部结构示意图。
图10提供的雾化器1与图2提供的雾化器1的区别在于：顶座121上分隔柱1214设置位置不同，相同部分不再赘述。
在本实施例中，分隔柱1214设于第一槽段1212b，且分隔柱1214靠近储液腔10的端面与凸起1215靠近储液腔10的表面平齐，以使换气槽1212具有两个换气口1212d。其中，由于分隔柱1214靠近储液腔10的端面与凸起1215靠近储液腔10的表面平齐，将第一槽段1212b靠近储液腔10的端口分隔为两个换气口1212d，两个换气口1212d与两个子储液腔101一一对应连通，可以实现与图6所示的换气槽1212相同的技术效果。
请参阅图11，图11是图1提供的电子雾化装置的雾化器又一实施例中密封件与雾化座的装配结构示意图。
图11提供的雾化器1与图2提供的雾化器1的区别在于：密封件14覆盖雾化座12的顶面部分的结构不同，相同部分不再赘述。
密封件14设于雾化座12的表面；密封件14覆盖雾化座12顶面的部分设有两个间隔设置的通气孔1212e，两个通气孔1212e分别与换气槽1212连通。两个通气孔1212e与两个子储液腔101一一对应连通。
密封件14的材料为硅胶，雾化座12(即顶座121和底座122)的材料为塑胶，相对于塑胶，硅胶与气溶胶生成基质的接触角相对于塑胶与气溶胶生成基质的接触角更大，通过在密封件14上设置两个间隔设置的通气孔1212e，通气孔1212e的孔壁容易粘气泡，进而更容易卡气泡，利于避免一直单侧换气。
可选的，换气槽1212和导气槽1213的具体结构与图6所示的换气槽1212和导气槽1213的具体结构相同，不在赘述。可以理解，在本实施例中，可以通过通气孔1212e的孔壁实现较好的卡泡效果，因此，图6中的分隔柱1214为可选结构。
以上仅为本申请的实施方式，并非因此限制本申请的专利范围，凡是利用本申请说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本申请的专利保护范围内。
