在本发明的一个实施例中，如图1～4，所示，空气循环装置1，包括支撑座100、风机200、离心风轮300、蜗壳400和驱动机构500。所述支撑座100内设有风孔101；所述蜗壳400与所述支撑座100转动连接，所述蜗壳400靠近所述支撑座100的一端设有与所述风孔101连通的通孔401，所述蜗壳400的侧面设有出风口402。所述风孔101内设有安装部102，所述安装部102与所述风孔101的内侧壁之间连接有多根连接筋103。所述风机200固设于所述安装部102上、且所述风机200的主轴穿过所述通孔101伸入所述蜗壳400内，所述离 心风轮300固定连接在所述风机200的主轴上，且所述离心风轮300位于所述蜗壳400内。所述驱动机构500连接所述蜗壳400，用于驱动驱动所述蜗壳400旋转。本实施例中，在风机200驱动离心风轮300旋转时，离心风轮300的叶片会将蜗壳400内的空气从出风口402甩出，并且同时外界的空气会从风孔101进入到蜗壳400内，因此出风口402能持续向外吹风，形成空气对流，让周围的空气循环起来；同时吹出的气流可吹向人体，达到散热降暑，也可用于吹向地面，或者其他的物体，达到对地面或者其他的物体快速风干。并且通过驱动机构500推动蜗壳400旋转，进而实现出风口402能不断旋转，因此代替了现有的360°风扇，由于只是蜗壳400旋转，风机200保持不动，因此避免接线缠绕的问题，从而使得整体结构简单化，生产制造的成本降低。并且，离心风轮300收纳在蜗壳400内，避免离心风轮200外露，并且出风口402在蜗壳400的侧面，因此能防止异物掉落到蜗壳400内部，对高速旋转的离心风轮200造成撞击损坏。
实现蜗壳400与支撑座100转动连接的一实施例，参照图1和图2，所述支撑座100的顶部沿所述风孔101的边缘向上延伸有第一连接套110，所述蜗壳400的底部沿所述通孔401边缘向下延伸有第二连接套410，所述第一连接套410转动的套设在所述第二连接套410上，或所述第二连接套410转动的套设在所述第一连接套110上。通过第一连接套110与第二连接套410连接，进而达到蜗壳400与支撑座100转动连接。
进一步，所述第一连接套110与所述第二连接套410之间还设有旋转耐磨套或轴承。本实施例中，通过增加旋转耐磨套或者轴承，能有效减小第一连接套110和第二连接套410的摩擦，能保证蜗壳400正常运行，并且减小磨损。
进一步，参照图1和图2，所述支撑座100上还设有外罩111，所述蜗壳400收纳与所述外罩111的腔体内，所述外罩111的侧壁分布有多个透气孔112。本实施例主要是应用在对人体散热降温中，具体是，通过离心风轮300甩出的高速气流会通过外置111缓冲后，透过透气孔112吹向人体，能避免气流直接从 出风口402吹出，导致风速过大，而对人体造成不适的问题。
为了使得蜗壳400在旋转的过程中，更为稳定，本实施例是在所述外罩111的顶端向下延伸有延伸部113，具体请参照图1和图2，所述蜗壳400的顶端向上延伸有与所述延伸部113转动连接的连接部411。本实施例中，通过对蜗壳400的上下两端限位，因此其转动时，更稳定。

进一步的，为了能满足消费者的使用需求，在如果只要小范围吹风，或者形成空气对流的情况下，只要蜗壳400在小范围摆动，本实施例中的第一驱动电机503为同步电机，因此只需要在蜗壳400的两侧分别放置有障碍物，因此在蜗壳400转动时，碰到障碍物时，同步电机则会反向转动，进而实现蜗壳400左右摆动的效果，并且可以根据需要，可以调整两个障碍物之间的位置，达到调整蜗壳400偏摆的角度，达到满足消费者的使用需求。
进一步，驱动机构500驱动蜗壳400旋转的另一实施方式，所述驱动机构包500包括第二驱动电机，第三齿轮和第四齿轮。所述连接部411转动的套设在所述延伸部113的外圈，所述外罩111内部的顶端设有第二驱动电机，所述连接部411的外圈设有第三齿轮，所述第二驱动电机的主轴上设有与所述第三齿轮啮合的第四齿轮。由于本实施方式，与上述的驱动方式相同，因此本实施方案避免重复累赘，故没有提供相应的附图和详细的描述。进一步的，所述第 二驱动电机为同步电机。

进一步，为了实现空气循环装置1能支撑在底面或者桌面上，以及增加蜗壳400运转的稳定性；本实施例是：还包括外壳600和底座700，所述外壳600的上端套设在所述支撑座100的底端，所述外壳600支撑在所述底座700上；所述外壳600的侧壁分布有多个透气孔601；所述底座700的顶端向上延伸有支撑部701，所述蜗壳400的底部向下延伸有与所述支撑部701转动连接的支撑套421，具体请参照图3和图4。本实施例中，通过外壳600支撑支撑座100，使得整体能站立在桌面或者底面上，本实施例中，通过外壳600能对气流起到缓冲作用，能避免气流直接从出风口402吹出，导致风速过大，而对人体造成不适的问题。
