具体实施方式
下面结合附图和实施例对本发明做进一步说明。
图1示出了一种气溶胶产生装置，其中的雾化器为贫氧加热的雾化器。
该雾化器包括：用于容装气溶胶基质1的管体3，配置于所述管体3的发热装置，配置于所述管体3外侧壁的支架17，以及固定于所述支架17外的雾化器壳体18。
其中，支架17顶端的周沿具有向外延伸的第一延伸部2，支架17底端的周沿具有向外延伸的第二延伸部6，第一与第二延伸部的外沿与雾化器壳体18固定连接，可以采用的固定 连接方式包括但不限于粘结、卡接、螺纹连接、过盈配合等，第一延伸部2、第二延伸部6、雾化器壳体18的内壁、与支架17的外壁之间形成空气隔热环4，所述雾化器壳体18的侧部配置有第一气孔7，所述第二延伸部6配置有连通所述管体3内部与第一气孔7的气道8，一单向阀13配置于所述管体3的底端。
上述雾化器，当将棒状结构的气溶胶基质1插入管体3内，启动加热后，单向阀13处于截止的状态，外界空气无法进入管体3及气溶胶基质1内，因此气溶胶基质1是在贫氧环境下加热的。当抽吸气溶胶基质1的过滤棒时，抽吸力产生的负压使单向阀13导通，外界空气从第一气孔7进入，经过气道8和单向阀13，然后进入气溶胶基质1内，与气溶胶基质1加热产生的气溶胶混合，一起被吸食。可见，借由上述单向阀13，可以使雾化器在贫氧环境下加热气溶胶基质。
而上述雾化器中形成的空气隔热环4，使得发热装置产生的热量需要经过该空气隔热环4后，才能传递至雾化器壳体18。由于空气的热导率小，可以起到较佳的隔热效果，所以能够减少传递到雾化器壳体18的热量，从而使得雾化器壳体18不容易发烫。
此外，上述支架17除了用来支撑管体3，还用于构造空气隔热环4，还集成有气道8，这使得雾化器的构成部件得以减少，雾化器的结构变得简单，其制造及组装变得更加容易。
一实施例中，发热装置包括发热针5及针座15，针座15嵌合固定于管体3的底端，将发热针5支撑于所述管体3内。在管体3内插入气溶胶基质1后，发热针5会穿入气溶胶基质1内部，发热针5包括电阻和/或发热电路，通电后会将电能转换为热能输出，从而对气溶胶基质1加热。针座15开设有连通所述管体3的上部和下部的第二气孔16。外界空气经过单向阀13后，从第二气孔16进入气溶胶基质1内。
一实施例中，针座15的底部配置有容置腔14，单向阀13采用硅胶鸭嘴阀，该硅胶鸭嘴阀配置在该容置腔14，该硅胶鸭嘴阀的边沿被压环12压接固定在针座15的底部。该结构利用针座15的内部空间来安放单向阀13，使得雾化器的纵向高度可以更小。此外，抽吸力因为要经过气溶胶基质1后作用于单向阀13，当抽吸力较小时，可能无法将单向阀13导通，而上述采用硅胶鸭嘴阀后，因为硅胶鸭嘴阀的阀口为对称结构，更容易导通，所以雾化器具有可靠性更好的特点。
上述管体3优选金属或陶瓷材料。
一实施例中，管体3的内径优选与气溶胶基质1的直径相匹配。借此结构，可以避免在气溶胶基质1与管体3之间进入空气。
一实施例中，雾化器壳体18于支架17的顶部还配置有盖体19，盖体19具体可通过螺接、卡接、粘结等固定工艺与雾化器壳体18固定。所述盖体19对应所述管体3的入口配置有置入孔，所述置入孔的直径与所述气溶胶基质1的过滤棒的外径匹配。在该实施方式下，气溶胶基质1的过滤棒可与盖体19上的置入孔之间形成密封，可阻止空气从该置入孔进入管体3内。
图1中雾化器的下方配置有主机，雾化器与主机组合构成了气溶胶产生装置。其中主机包括主机壳体11、电池5及控制电路，控制电路设置在电路板4，其中，主机壳体11与雾化器壳体18一体成型，电池5固定在雾化器的底部，电路板4固定在主机壳体11内电池5的一侧，主机壳体11上设置有电源开关，打开电源开关后，发热针5的供电回路接通，电池10向发热针5供电，发热针5输出热量，对气溶胶基质1加热。当抽吸气溶胶基质1的过滤棒时，单向阀13导通，外界空气从第一气孔7进入，经过气道8和单向阀13，然后进入气溶胶基质1内，与气溶胶基质1加热产生的气溶胶混合，一起被吸食。
可见，该气溶胶产生装置结构简单，使用方便，可以实现贫氧环境加热气溶胶基质，壳体不容易发烫。
图2示出了另一种气溶胶产生装置，其中的雾化器也为贫氧加热的雾化器。
参照图2，该雾化器包括：用于容装气溶胶基质的管体3，配置于所述管体3的发热装置，配置于所述管体3外侧壁的支架17，以及固定于所述支架17外的雾化器壳体18。
其中，支架17顶端的周沿具有向外延伸的第一延伸部2，支架17底端的周沿具有向外延伸的第二延伸部6，第一与第二延伸部的外沿与雾化器壳体18固定连接，可以采用的固定连接方式包括但不限于粘结、卡接、螺纹连接、过盈配合等，第一延伸部2、第二延伸部6、雾化器壳体18的内壁、与支架17的外壁之间形成空气隔热环4，雾化器壳体18的侧部配置有第一气孔7，所述第二延伸部6配置有连通所述管体3内部与第一气孔7的气道8，一单向阀配13置于所述气道8的靠近所述第一气孔7的一端。
该雾化器，当将棒状结构的气溶胶基质1插入管体3内，启动加热后，单向阀13处于截止的状态，外界空气无法进入管体3及气溶胶基质1内，因此气溶胶基质1是在贫氧环境下加热的。当抽吸气溶胶基质1的过滤棒时，抽吸力产生的负压使单向阀13导通，外界空气从第一气孔7进入，经过气道8和单向阀13，然后进入气溶胶基质1内，与气溶胶基质1加热产生的气溶胶混合，一起被吸食。可见，借由上述单向阀13，可以使雾化器在贫氧环境下加热气溶胶基质1。
而上述雾化器中形成的空气隔热环4，使得发热装置产生的热量需要经过该空气隔热环4后，才能传递至雾化器壳体18。由于空气的热导率小，可以起到较佳的隔热效果，所以能够减少传递到雾化器壳体18的热量，从而使得雾化器壳体18不容易发烫。
此外，上述支架17除了用来支撑管体3，还用于构造空气隔热环4，还集成有气道8，这使得雾化器的构成部件得以减少，雾化器的结构变得简单，其制造及组装变得更加容易。
参照图2，该实施例中，发热装置包括线圈20，线圈20缠绕固定在支架17，并与管体3相对，线圈20与所述管体3构成了电磁发热装置。其中，管体3优选铁或含铁合金，或者其它的能够被线圈的磁场作用，而产生热能的材料。工作时，给线圈20通电，电磁加热效应将管体3加热，管体3将热量传递给插设于其内的气溶胶基质1，从而对气溶胶基质1加热，产生气溶胶。
该实施例中，单向阀13采用硅胶鸭嘴阀，所述硅胶鸭嘴阀的边沿压接固定于雾化器壳体18与所述第二延伸部6的外端之间。抽吸力因为要经过气溶胶基质1后作用于单向阀13，当抽吸力较小时，可能无法将单向阀13导通，而上述采用硅胶鸭嘴阀后，因为硅胶鸭嘴阀的阀口为对称结构，更容易导通，所以雾化器具有可靠性更好的特点。
该实施例中，雾化器壳体18于支架17的顶部也配置有盖体19，盖体19具有供气溶胶基质1进入所述管体3内的置入孔，置入孔的孔径与气溶胶基质1的过滤棒的外径匹配。
图2中雾化器的下方配置有主机，主机与雾化器二者组合构成了气溶胶产生装置。其中主机包括主机壳体11、电池10及控制电路，控制电路设置在电路板9，其中，主机壳体11与雾化器壳体18一体成型，电池10固定在雾化器的底部，电路板9固定在主机壳体11内电池10的一侧，主机壳体11上设置有电源开关，打开电源开关后，线圈20的供电回路接通，电池向线圈20供电，线圈20产生磁场将管体3加热，管体3的热量传递给气溶胶基质1，对气溶胶基质加热。当抽吸气溶胶基质1的过滤棒时，单向阀13导通，外界空气从第一气孔7进入，经过单向阀13和气道8，然后进入气溶胶基质1内，与气溶胶基质加热产生的气溶胶混合，一起被吸食。
可见，该气溶胶产生装置结构简单，使用方便，可以实现贫氧环境加热气溶胶基质，壳体不容易发烫。
