传统的雾化装置包括壳体、设置于壳体底端的雾化器组件，以及设置于壳体和雾化器组件之间的密封圈。其中，壳体具有用于储存气溶胶基质的储液腔。然而，该雾化装置容易在安装过程中因壳体与密封圈之间发生干涉而导致密封圈出现挤胶现象。
本申请的发明人经过研究发现，传统的雾化装置在安装过程中因壳体与密封圈之间发生干涉而导致密封圈出现挤胶现象的原因在于：在该雾化装置装配时，需要先将密封圈套设于雾化器组件，然后再将雾化器组件卡接于壳体的底端，因壳体的管壁较薄，对密封圈的约束不够，在雾化器组件卡接于壳体的底端的过程中，壳体与密封圈之间会发生干涉，导致密封圈被挤压变形，进而导致密封圈出现挤胶现象。
为了解决传统的雾化装置容易在安装过程中因壳体与密封圈之间发生干涉而导致密封圈出现挤胶现象的问题，本申请的发明人经过深入研究，设计一种雾化器，包括壳体和发热组件，其中，发热组件包括发热顶盖、发热座、发热体以及第一密封件，可将发热顶盖配接于壳体，并将发热座和发热体一起容置于发热顶盖的安装槽内，且第一密封件密封设置于发热顶盖与发热座之间，发热顶盖的壁厚较大，一方面，发热顶盖可对第一密封件起到约束和导向作用，第一密封件不易挤压变形，也不会出现挤胶现象，发热顶盖也不易出现鼓管现象，另一方面，第一密封件与壳体互不干涉，也不会因壳体鼓管而导致该雾化器的雾化腔的密封性不好，可有效提高雾化腔的密封性。
图1示出了本申请一实施例中的雾化器10的剖视示意图。
在一些实施例中，请参阅图1，并结合参阅图2及图3，本申请一实施例提供的雾化器10，包括壳体110和发热组件。
发热组件包括发热顶盖120、发热座130、发热体140以及第一密封件150。发热座130和发热体140均装配于发热顶盖120内，且发热体140具有发热面1401，第一密封件150设置于发热顶盖120与发热座130之间，以将发热顶盖120密封。且发热座130、发热顶盖 120和发热面1401围设出雾化腔1212，该发热体140工作时，导流至发热体140的发热面1401的气溶胶基质可经由发热体140加热而在雾化腔1212内形成供使用者吸食的气溶胶。
在发热座130和发热体140一起安装于发热顶盖120的过程中，因第一密封件150设于发热座130和发热顶盖120之间，且发热顶盖120的壁厚较大，可对第一密封件150起到约束和导向作用，第一密封件150不易挤压变形，也不会出现挤胶现象，发热顶盖120也不易出现鼓管现象。
在一些实施例中，发热顶盖120内开设一安装槽121，安装槽121在与发热面1401相交的第一方向F1上开设有安装口1211，发热座130沿第一方向F1经安装口1211配接于安装槽121内，第一密封件150设置于发热座130和安装槽121的侧壁之间。如此，发热体140收容于安装槽121内，流入雾化腔1212内的气溶胶基质也能更好地经由雾化腔1212内的发热体140加热而形成气溶胶，以供使用者吸食。
在一些实施例中，请参阅图1及图3，发热座130上环设有用于安装第一密封件150的环形凹槽131，第一密封件150过盈配合于环形凹槽131。
如此，在安装过程中，可使第一密封件150很好固定于发热座130，在将发热座130和发热体140安装于安装槽121的过程中，可使第一密封件150过盈配合于环形凹槽131和安装槽121的侧壁之间，以使发热座130定位于安装槽121内，可提高雾化器10的密封可靠性。
在一些实施例中，请参阅图4，安装槽121的侧壁包括沿平行于发热面1401的方向相对设置的两个第一侧壁121a，以及沿第二方向F2相对设置的两个第二侧壁121b。第一侧壁121a和第二侧壁121b的连接处形成弧形导向面121c。其中，第一方向F1与第二方向F2彼此垂直，且垂直于发热面1401。
在将发热座130和发热体140安装于安装槽121的过程中，可使发热座130沿第一方向F1经安装口1211配接于安装槽121，密封连接于发热座130和安装槽121之间的第一密封件150在弧形导向面121c的导向作用下，不易挤压变形，更能提高雾化腔1212的密封性。
如图1及图4所示，平行于发热面1401的方向为上下方向，第一方向F1为左右方向，第二方向F2为前后方向，也就是说，在发热座130沿左右方向经安装口1211配接于安装槽121的过程中，弧形导向面121c能够很好地对沿左右方向移动的发热座130上的第一密封件150起导向作用。
在一些实施例中，请参阅图3及图4，发热座130和安装槽121中，两者之一设有定位件132，两者之另一设有与定位件132相适配的定位槽123。
可使发热座130更好地定位于安装槽121内，有利于发热座130上的第一密封件150定位于安装槽121内，一定程度上也可提高雾化器10的密封可靠性。
如图3和图4所示，定位件132设置于发热座130，定位槽123设置于安装槽121， 在发热座130沿第一方向F1经安装口1211配接于安装槽121的过程中，定位件132可连接于定位槽123，以使发热座130更好地定位于安装槽121内。
定位件132可以卡接于安装槽121，如图4所示，定位件132为卡扣，定位槽123为与卡扣相适配的卡槽。也可以采用其他可拆卸地连接方式将定位件132定位于安装槽121内。
在另一些实施例中，定位件132可设置于安装槽121，定位槽123设置于发热座130，以使发热座130更好地定位于安装槽121内。
在一些实施例中，请参阅图3及图4，定位件132设置于发热座130沿平行于发热面1401的方向的相对两侧，安装槽121设有与定位件132一一适配的定位槽123，如此，在发热座130沿第一方向F1经安装口1211配接于安装槽121的过程中，可更好地使发热座130定位于安装槽121内。
在一些实施例中，请参阅图4，两个第二侧壁121b均设有倒扣128，以使配接于安装槽121的发热座130限位固定于两个第二侧壁121b上的倒扣128之间，一定程度上也能提高雾化器10的密封可靠性。
在一些实施例中，请参阅图4，两个第二侧壁121b均设有沿壳体110的轴向F轴向间隔设置的两个倒扣128，可更好地使发热座130固定于安装槽121内，一定程度上也能提高雾化器10的密封可靠性。
本申请一实施例提供的雾化器10，包括壳体110以及上述的发热组件。发热顶盖120配接于壳体110内并与壳体110界定形成一储液腔1102，发热顶盖120位于壳体110的轴向F轴向上，且壳体110的轴向平行于发热面1401，以便储液腔1102内的气溶胶基质流入发热顶盖120内。壳体110内沿其轴向形成有出气通道1101，发热座130、发热顶盖120和发热面1401围设出一与出气通道1101连通的雾化腔1212，发热顶盖120上开设有与雾化腔1212连通的进气口125。
该雾化器10的安装过程如下：将发热座130、发热体140以及第一密封件150一起经安装口1211放入安装槽121内，以使发热体140收容于安装槽121内，并使第一密封件150设置于发热顶盖120与发热座130之间，以将安装槽121密封，如此，在发热座130和发热体140一起经过安装口1211而容置于安装槽121内的过程中，因发热顶盖120的壁厚较大，发热座130、第一密封件150和发热体140组成的整体可沿着安装槽121的侧壁安装于安装槽121内，一方面，发热顶盖120可对第一密封件150起到约束和导向作用，第一密封件150不易挤压变形，也不会出现挤胶现象，发热顶盖120不易出现鼓管现象；另一方面，第一密封件150与壳体110互不干涉，避免在安装过程中因壳体110出现鼓管现象而影响雾化腔1212的密封性，雾化腔1212内的气溶胶不易泄漏，可有效提高雾化腔1212的密封性。
需要说明的是，通常，为了追求轻薄化设计，壳体110的壁厚较薄，而发热顶盖120不属于雾化器10的外壳组件，为了保证发热顶盖120的质量，发热顶盖120的壁厚较厚，有 利于提高雾化腔1212的密封性。
该雾化器10使用时，储液腔1102内的气溶胶基质可流入雾化腔1212内，雾化腔1212内的发热体140可使流入雾化腔1212的气溶胶基质加热而形成气溶胶，以供使用者吸食。
在一些实施例中，第一方向F1垂直于壳体110的轴向F轴向。如图1所示，壳体110的轴向F轴向为纵向方向，第一方向F1为横向方向。也就是说，发热座130和发热体140相对于壳体110横向设置。
在一些实施例中，请参阅图1，壳体110具有围绕于出气通道1101的储液腔1102，发热顶盖120上开设有一连通于储液腔1102与雾化腔1212之间的进液腔122，进液腔122与安装槽121沿第一方向F1排布。
如此，储液腔1102能够通过进液腔122向雾化腔1212内的发热体140供应气溶胶基质。具体地，储液腔1102内储存的气溶胶基质可沿壳体110的轴向F轴向流入进液腔122内，进而供应至发热体140，可利用发热体140加热气溶胶基质而雾化形成气溶胶，以供使用者吸食。
在一些实施例中，请参阅图1及图4，发热顶盖120上设有一连通于安装槽121和进液腔122之间的台阶孔124，发热体140沿第一方向F1密封连接于台阶孔124的台阶面1241。发热体140具有与台阶孔124相连通的导液通道，以使流入进液腔122内的气溶胶基质能够通过导液通道导流至发热体140的发热面1401。
因发热体140沿第一方向F1密封连接于台阶孔124的台阶面1241，流入进液腔122内的气溶胶基质不会直接流入雾化腔1212内，该气溶胶基质可通过发热体140的导液通道导流至发热体140的发热面1401，以在雾化腔1212内被加热而形成供使用者吸食的气溶胶。
在一些实施例中，请参阅图1及图3，发热体140包括密封连接于台阶面1241的导液基体141，以及设置于导液基体141远离进液腔122一侧的发热件142。导液通道设置于导液基体141，以将流入进液腔122的气溶胶基质导流至发热件142。如此，流入进液腔122内的气溶胶基质能够通过导液通道导流至雾化腔1212内的发热件142处，以便被发热件142加热而形成供使用者吸食的气溶胶。
在一些实施例中，导液基体141为多孔结构，如此，流入进液腔122内的气溶胶基质能够通过导液基体141的孔洞导流至发热件142处。
在一些实施例中，导液基体141可以为由多孔陶瓷、纤维棉等材料形成的多孔结构。
在一些实施例中，请参阅图1及图3，发热件142远离导液基体141的一侧设有电极143，电极143沿第一方向F1穿设于发热座130，以外接电源。一方面，方便该发热件142外接电源，可提高该雾化器10的便利性。另一方面，可将发热体140连接于发热座130，以便发热体140随发热座130一起安装在安装槽121内。
在一些实施例中，请参阅图1及图3，导液基体141远离发热件142的一侧设有密封 圈144，以使导液基体141远离发热件142的一侧密封连接于台阶孔124的台阶面1241，进而可使发热体140沿第一方向F1密封连接于台阶孔124的台阶面1241。
在一些实施例中，请参阅图1，并结合参阅图5，雾化器10还包括第二密封件160，第二密封件160连接于发热顶盖120朝向壳体110的一侧，以使发热顶盖120密封连接于壳体110。第二密封件160设有开口161，开口161分别与出气通道1101和雾化腔1212相连通。
如此，该雾化器10使用时，储液腔1102内储存的气溶胶基质供应至位于雾化腔1212内的发热体140后，可利用发热体140使气溶胶基质雾化形成气溶胶，形成的气溶胶可通过出气通道1101而被使用者吸食。另外，发热顶盖120密封连接于壳体110，可进一步地提高雾化器10的密封性。
在一些实施例中，请参阅图1及图4，发热顶盖120的底部设有与雾化腔1212相连通的进气口125。该雾化器10使用时，使用者的嘴对着出气通道1101远离雾化腔1212的一侧，可使出气通道1101内形成负压，该雾化器10所处环境内的空气可在负压作用下经过进气口125、雾化腔1212和出气通道1101而被使用者抽吸，进而使雾化腔1212内形成的气溶胶随着这部分空气而被使用者吸食，提高气溶胶的吸食效果。
在一些实施例中，请参阅图1及图5，第二密封件160上设有形变部162，形变部162被构造为能够响应于储液腔1102内的压力变化而发生形变。
在雾化器10的使用过程中，储液腔1102内的气溶胶基质逐渐消耗而使储液腔1102内产生负压，从而影响到对发热体140的供液速度，为了避免雾化腔1212内因气溶胶基质的消耗速度大于供应速度而导致出现雾化腔1212干烧发焦的情况，设置的形变部162能够在气溶胶基质逐渐消耗过程中朝向储液腔1102形变，以对储液腔1102内的气压做出补偿，防止出现雾化腔1212干烧发焦的情况。
在一些实施例中，请参阅图5，形变部162与第二密封件160的顶部一体成型，且形变部162的厚度小于第二密封件160的顶部的厚度。
可以理解，形变部162的厚度较薄，容易相对于第二密封件160的顶部发生形变，以便在气溶胶基质逐渐消耗过程中，利用形变部162防止出现雾化腔1212干烧发焦的情况。
在一些实施例中，形变部162的厚度为0.01-0.5mm。利用该形变部162可很好地对储液腔1102内的气压做出补偿，防止出现雾化腔1212干烧发焦的情况。
发热顶盖120上设有位于形变部162远离储液腔1102一侧的形变空间1201，以为形变部162提供沿壳体110的轴向F轴向朝向远离储液腔1102的一侧形变的空间。提高该雾化器10的可靠性。
在一些实施例中，请参阅图5及图6，第二密封件160上设有第一连接部163，发热顶盖120设有与第一连接部163卡接的第一连接卡槽1271，可使第二密封件160连接于发热顶盖120朝向壳体110的一侧。
请参阅图6及图7，第一连接部163呈筒状，开口161形成于第一连接部163的内壁，且储液腔1102内设有与第一连接部163远离第一连接卡槽1271一端卡接的通气管111，出气通道1101形成于通气管111的内壁，第一连接卡槽1271与雾化腔1212相连通，如此，该雾化器10使用时，雾化腔1212内形成的气溶胶可依次通过第一连接卡槽1271、开口161和通气管111而被使用者吸食。
在一些实施例中，请参阅图5及图6，第二密封件160上第二连接部164，发热顶盖120与第二连接部164卡接的第二连接卡槽1272，第二密封件160和发热顶盖120通过第二连接部164和第二连接卡槽1272卡接，可提高两者的连接牢固性。
在一些实施例中，请参阅图5，第二密封件160设有阻断部件165，阻断部件165沿壳体110的轴向F轴向穿设于进液腔122，并伸出发热顶盖120外。阻断部件165被构造为能够在预设拉力下脱离于第二密封件160，以在第二密封件160上形成出液口。其中。出液口分别与储液腔1102和进液腔122相连通，以使储液腔1102能够向进液腔122供应气溶胶基质。
雾化器10使用前，阻断部件165用于阻断储液腔1102和进液腔122，有利于使储液腔1102内的气溶胶基质保持洁净。
雾化器10使用时，使用者可施力于阻断部件165，以使阻断部件165在预设拉力下脱离于第二密封件160，并在第二密封件160上形成出液口，以便储液腔1102内的气溶胶基质经过出液口而流入进液腔122内，进而供应至雾化腔1212内的发热体140，以利用发热体140加热气溶胶基质而形成供使用者吸食的气溶胶。
在一些实施例中，请参阅图4，发热顶盖120的底部设有供阻断部件165伸出的过孔126，过孔126与进液腔122相连通。在预设拉力下，脱离于第二密封件160的阻断部件165能够堵设于过孔126。
在预设拉力下，可使脱离于第二密封件160的阻断部件165堵设于过孔126，以提高进液腔122的密封性，避免流入进液腔122的气溶胶基质通过该过孔126而向外流出。
在一些实施例中，请参阅图5，第二密封件160设有加强部166，加强部166上设有连接于阻断部件165的薄弱部167，以使阻断部件165在预设拉力下脱离于第二密封件160。
具体到如图5所示的实施例中，壳体110的轴向F轴向为上下方向，可向下拉阻断部件165，使得薄弱部167被拉断，进而使得阻断部件165在预设拉力下脱离于第二密封件160。
在一些实施例中，请参阅图5及图6，发热顶盖120朝向第二密封件160的一侧设有围绕进液腔122的多个限位件129，多个限位件129界定出固定加强部166的加固槽。再将第二密封件160连接于发热顶盖120朝向壳体110的一侧的过程中，可使加强部166固定于该加固槽中，以提高加强部166的牢固性，以便在预设拉力下加强部166和阻断部件165之间的薄弱部167被拉断。
在一些实施例中，请参阅图2及图7，雾化器10还包括盖设于壳体110的底盖170，底盖170和壳体110之间界定出容纳发热组件的容纳空间，以便发热组件收容于该容纳空间内。
发热座130上设有沿第一方向F1伸出安装槽121的延伸部133，底盖170沿第一方向F1的一端设有与延伸部133卡接的第三连接卡槽171，底盖170沿第一方向F1的另一端卡接于壳体110上的第五连接卡槽112。如此，可使底盖170分别卡接于发热座130和壳体110。
底盖170的外侧壁设有第四连接卡槽172，壳体110上设有卡接于第四连接卡槽172的连接卡扣113，可提高底盖170与壳体110的连接牢固性。
底盖170设有供阻断部件165沿壳体110的轴向F轴向穿过的过道173，以便使用者在底盖170外对阻断部件165施加沿壳体110的轴向F轴向的预设拉力，以便储液腔1102内的气溶胶基质经过出液口而流入进液腔122内，进而供应至雾化腔1212内的发热体140。
在一些实施例中，请参阅图1，本申请一实施例提供的雾化器10，包括壳体110、发热组件和第二密封件160。该雾化器10的使用过程如下：先对阻断部件165施加沿壳体110的轴向F轴向的预设拉力，使阻断部件165在预设拉力下脱离于第二密封件160，并在第二密封件160上形成出液口，且使阻断部件165堵设于过孔126。如此，储液腔1102内的气溶胶基质经过出液口而流入进液腔122内，流入进液腔122内的气溶胶基质能够通过导液基体141的孔洞导流至发热件142处，并被发热件142加热而形成供使用者吸食的气溶胶。
本申请一实施例提供的一种电子雾化装置，包括上述的雾化器10。
