以下结合附图对本发明的优选实施例进行说明，应当理解，此处所描述的优选实施例仅用于说明和解释本发明，并不用于限定本发明。
如图1-图3所示，本发明提供一种产生变化气流装置第一实施例。
该产生变化气流装置包括设有腔室67的腔体6，该腔体6设有与腔室67连通的气嘴63，在腔体6的底部设有使腔室67内部空气流动，并在气嘴63形成聚集气流的空气驱动机构，所述腔体6的内壁61为曲面。
具体地说，所述空气驱动机构包括与腔体6连接的弹性部件66和与弹性部件66连接直线往复运动的振动壳62，该振动壳62通过弹性部件66与由硬壳61构成的腔室67密封连接。所述振动壳62和气嘴63分别位于腔体6相对的两端或两侧。所述空气驱动机构还包括电机1和设于电机转轴的偏心部件2，所述偏心部件2通过连杆5，并通过振动壳62使弹性部件66发生形变从而使振动壳62产生振动，改变腔室67大小。在所述偏心部件2与连杆5之间通过承轴3实现活动连接，而且该承轴3通过限位件3将承轴3固定在偏心部件2上。
在本实施例中，所述腔体6采用包括球形结构，且该腔体6采用刚性材料制作的刚性腔体，如采用硬质的塑胶注塑成型。
所述气嘴63采用弹性材质，其上设有开口64。所述弹性部件66包括设有增大振动行程和弹性的振动膜，该振动膜设有环形褶皱671。所述振动膜与开口64的正投影面积之比不小于2。通过试验，能在压缩腔体6内空气时，可以在开口64处形成较好的气压作用力。
根据需要，所述腔室67的体积变化与最小体积的比值小于1/110，优选的比值小于1/15。通过试验，通过上述设置可以形成较好的空气变化气压，可以避免压力过小时在气嘴63处形成的空气作用较小，无法适应应用场情的需要；压力过大时需要空气驱动机构产生较大行程，导致产品体积增加。该述腔室67的体积变化与最小体积的比值小于可以独立实施，也可以与其他实施例组合实施。
当产生变化气流装置工作时，通过将所述振动壳62迅速向后移动，使弹性部件66处于拉伸状态，由于此时腔体6的空间突然增大，导致其腔室67压强变小，在气嘴63的开口64形成速度流动的空气流，该腔室670内部空间呈扩散状，通过气嘴63的空气在其内形成两气流，即沿振动壳62移动方向的第一气流10和靠近内壁61的第二气流20。由于内壁60为曲面结构，第二气流20在内壁61作用下改变方向，同时汇聚到振动壳62附近。当振动壳62向气嘴63方向运动时，还原之前的空气流动路径，并在气嘴63汇集，从而在气嘴63处形成瞬间气流用作。
在上述实施例中，所述振动壳62与连杆5可以采用一体结构，也可以根据需要采用可拆或两个部件活动或固定连接的分体结构实现。
如图4所示，所述空气驱动机构包括与腔体6连接的弹性振动部件60，该弹性振动部件60通过连杆5和设于电机转轴的偏心部件2与电机1连接，而且弹性振动部件60与连杆5只能采用分体结构实现。其他结构和工作过程与上述相同，不再赘述。
如图5-6所示，所述腔体6采用椭圆形或橄榄型结构，其他结构与上述相同，不再赘述。在上述实施例中，所述振动壳62或弹性振动部件60都为曲面结构。如图7所示，为了更好地在进行气嘴63处空气在压缩时产生更大的压差，在所述腔体，也即腔体的内壁60上设有多个将腔室67内空气引导至气嘴63的引导机构。该引导机构包括设于腔室内壁多个导向条68，相邻的导向条68之间形成引导槽69。所述导向条68端自气嘴63沿腔室67的内壁60向振动壳62方向伸延直至振动壳62附近。在此实施例中，所述振动壳62为平面结构，可以在相同振辐下可以有较在空气变化量，所述振动壳62为平面时，该振动壳62的直径最优为3-30mm。所述振动壳62与连杆5可以采用一体结构，也可以根据需要采用可拆或两个部件活动或固定连接的分体结构实现。
由于腔体的内壁呈向气嘴聚集的曲面，该曲面的内壁能对气流进行汇聚及压缩，当腔体受到压缩体积变小时，腔体内的空气在开口处急速聚集、压缩而压强急剧增大，在气嘴形成较大的喷射气流，该气流在气嘴处能形成较大的作用力。当气流用于按摩时，可以对人体形成拍打按摩效果；当腔体体积增大时，气嘴处的空气被急速抽离，压强快速减小，产生负压并吸附人体，从而对人体进行吸附式按摩。振动壳或振动膜面积大于开口的面积，振动壳或振动膜所能作用的面积大，能有效的推动腔体内的空气朝开口处运动或迁移开口处的空气朝远离开口的方向运动，提高了按摩器的气体拍打按摩或吸附式按摩的按摩效果。腔体的体积变化与最小体积的比值小于1/10，优选小于1/15，使开口处所产生的气体拍打力度和吸附力度不过大，以轻柔的方式进行拍打和吸附按摩，不会由于拍打和吸附力度过大造成人体皮肤的红肿、疼痛等不良反应，在保证按摩效果的前提下提高用户的按摩舒适度。
如图8-11所示，所述腔室6也可以采用漏斗或类似漏斗等形状，当腔室6采用类漏斗状时，所述振动壳62位于径向最大处，这样可以在较小振辐下，能产生最大的空气压力变化，在气嘴63处形成的气流作用更明显。所述其他结构、工作过程与上述实施例相同，不再赘述。
以上各实施例中的具体部件可以与其他实例进行组合实施，具体组合实施不再赘述。
如图1-11所示，本发明还提供一种按摩器实施例。
该按摩器包括产生变化气流装置和驱动产生变化气流装置连续产生变化气流的驱动装置，该产生变化气流装置包括设有腔室67的腔体6，该腔体6设有与腔室67连通的气嘴63，在腔体6的底部设有使腔室67内部空气流动，并在气嘴63形成聚集气流的空气驱动机构，所述腔体6的内壁61为曲面。所述空气驱动机构采用上述实施例结构。
该具体地说，所述空气驱动机构包括与腔体6连接的弹性部件66和与弹性部件66连接直线往复运动的振动壳62，该振动壳62通过弹性部件66与由硬壳61构成的腔室67密封连接。所述振动壳62和气嘴63分别位于腔体6相对的两端或两侧。所述空气驱动机构还包括电机1和设于电机转轴的偏心部件2，所述偏心部件2通过连杆5，并通过振动壳62使弹性部件66发生形变从而使振动壳62产生振动，改变腔室67大小。在所述偏心部件2与连杆5之间通过承轴3实现活动连接，而且该承轴3通过限位件3将承轴3固定在偏心部件2上。
在本实施例中，所述腔体6采用包括球形结构，且该腔体6采用刚性材料制作的刚性腔体，如采用硬质的塑胶注塑成型。
所述气嘴63采用弹性材质，其上设有开口64。所述弹性部件66包括设有增大振动行程和弹性的振动膜，该振动膜设有环形褶皱671。所述振动膜与开口64的正投影面积之比不小于2。通过试验，能在压缩腔体6内空气时，可以在开口64处形成较好的气压作用力。
根据需要，所述腔室67的体积变化与最小体积的比值小于1/110，优选的比值小于1/15。通过试验，通过上述设置可以形成较好的空气变化气压，可以避免压力过小时在气嘴63处形成的空气作用较小，无法适应应用场情的需要；压力过大时需要空气驱动机构产生较大行程，导致产品体积增加。该述腔室67的体积变化与最小体积的比值小于可以独立实施，也可以与其他实施例组合实施。
当产生变化气流装置工作时，通过将所述振动壳62迅速向后移动，使弹性部件66处于拉伸状态，由于此时腔体6的空间突然增大，导致其腔室67压强变小，在气嘴63的开口64形成速度流动的空气流，该腔室670内部空间呈扩散状，通过气嘴63的空气在其内形成两气流，即沿振动壳62移动方向的第一气流10和靠近内壁61的第二气流20。由于内壁60为曲面结构，第二气流20在内壁61作用下改变方向，同时汇聚到振动壳62附近。当振动壳62向气嘴63方向运动时，还原之前的空气流动路径，并在气嘴63汇集，从而在气嘴63处形成瞬间气流用作。
在上述实施例中，所述振动壳62与连杆5可以采用一体结构，也可以根据需要采用可拆或两个部件活动或固定连接的分体结构实现。
如图4所示，所述空气驱动机构包括与腔体6连接的弹性振动部件60，该弹性振动部件60通过连杆5和设于电机转轴的偏心部件2与电机1连接，而且弹性振动部件60与连杆5只能采用分体结构实现。其他结构和工作过程与上述相同，不再赘述。
如图5-6所示，所述腔体6采用椭圆形或橄榄型结构，其他结构与上述相同，不再赘述。在上述实施例中，所述振动壳62或弹性振动部件60都为曲面结构。如图7所示，为了更好地在进行气嘴63处空气在压缩时产生更大的压差，在所述腔体，也即腔体的内壁60上设有多个将腔室67内空气引导至气嘴63的引导机构。该引导机构包括设于腔室内壁多个导向条68，相邻的导向条68之间形成引导槽69。所述导向条68端自气嘴63沿腔室67的内壁60向振动壳62方向伸延直至振动壳62附近。在此实施例中，所述振动壳62为平面结构，可以在相同振辐下可以有较在空气变化量，所述振动壳62为平面时，该振动壳62的直径最优为3-30mm。所述振动壳62与连杆5可以采用一体结构，也可以根据需要采用可拆或两个部件活动或固定连接的分体结构实现。
由于腔体的内壁呈向气嘴聚集的曲面，该曲面的内壁能对气流进行汇聚及压缩，当腔体受到压缩体积变小时，腔体内的空气在开口处急速聚集、压缩而压强急剧增大，在气嘴形成较大的喷射气流，该气流在气嘴处能形成较大的作用力。当气流用于按摩时，可以对人体形成拍打按摩效果；当腔体体积增大时，气嘴处的空气被急速抽离，压强快速减小，产生负压并吸附人体，从而对人体进行吸附式按摩。振动壳或振动膜面积大于开口的面积，振动壳或振动膜所能作用的面积大，能有效的推动腔体内的空气朝开口处运动或迁移开口处的空气朝远离开口的方向运动，提高了按摩器的气体拍打按摩或吸附式按摩的按摩效果。腔体的体积变化与最小体积的比值小于1/10，优选小于1/15，使开口处所产生的气体拍打力度和吸附力度不过大，以轻柔的方式进行拍打和吸附按摩，不会由于拍打和吸附力度过大造成人体皮肤的红肿、疼痛等不良反应，在保证按摩效果的前提下提高用户的按摩舒适度。
如图8-11所示，所述腔室6也可以采用漏斗或类似漏斗等形状，当腔室6采用类漏斗状时，所述振动壳62位于径向最大处，这样可以在较小振辐下，能产生最大的空气压力变化，在气嘴63处形成的气流作用更明显。所述其他结构、工作过程与上述实施例相同，不再赘述。
以上各实施例中的具体部件可以与其他实例进行组合实施，具体组合实施不再赘述。
以上实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换，而这些修改或替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的精神和范围。
