本发明一种动态压力发生装置及按摩器，其中动态压力发生装置，包括具有开口的腔体、设于所述腔体内的运动部件以及驱动所述运动部件在所述腔体内往复运动的驱动机构，其中，所述腔体的腔壁为刚性腔壁，所述运动部件与所述腔壁之间设有配合间隙，且所述运动部件在所述腔体内往复运动时，所述开口处产生周期性交替的正压和负压。
与相关技术相比，本发明提供的动态压力发生装置包括具有开口的腔体、设于所述腔体内的运动部件以及驱动所述运动部件在所述腔体内往复运动的驱动机构，其中，所述腔体的腔壁为刚性腔壁，所述运动部件与所述腔壁之间具有间隙，所述运动部件在所述腔体内往复运动时，所述开口处产生周期性交替的正压和负压以达到吸附放松的效果。这种动态压力发生装置不仅结构简单，而且吸附按摩效果好。
由于配合配合间隙不大于0.1MM，既能在运动部件作往复运动时在腔室内产生压力变化，即产生动态压力，并能在负压开口处产生负压，运动部件与腔室间既可以产生负压，又可以减少产生动态压力变化时的阻力。
在内套筒外设有弹性外套筒，一方面可以减少振动向外传递，另一方面也能减小活塞运动时与内套筒间接触发生噪音向外传输，从而可以达到减少噪音的目的。可以广泛用于按摩等产品上。

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和图2所示，本发明提供一种动态压力发生装置的第一实施例。
该动态压力发生装置包括具有开口1A的腔体1、设于所述腔体1内的运动部件3以及驱动所述运动部件3在所述腔体1内往复运动的驱动机构5，其中，所述腔体1的腔壁为刚性腔壁，所述运动部件3与所述腔壁之间具有间隙1B（换而言之，所述运动部件3悬置于所述腔体1内），且所述运动部件3在所述腔体1内往复运动时会周期性挤压所述腔体1内的空气，从而会使得所述开口1A处产生周期性交替的正压和负压。
如图2所示，所述运动部件3呈板状。可以理解的是，所述运动部件3的形状并不局限于呈板状，例如，所述运动部件还可以设置成呈弧形状。
在本实施例中，所述腔壁在所述开口1A处连接有由柔性材料制成的囊体8，所述囊体8具有与所述开口1A连通的气道81，所述气道81在其远离所述开口1A的一端形成吸附口83。由于所述吸附口83与所述开口1A连通，所述吸附口83处也会产生周期性交替的正压和负压。
在本实施例中，所述囊体8与所述腔体1一体成型。可以理解的是，在其他实施方式中，所述囊体8与所述腔体1也可以通过胶黏等方式连接。
如图2所示，所述腔壁包括沿所述运动部件3的运动方向延伸并围合形成所述开口1A的第一腔壁11以及设于所述第一腔壁11远离所述开口1A一端的第二腔壁13，所述运动部件3与所述第一腔壁11之间具有所述间隙1B，所述第二腔壁13活动地穿设有传递件7，所述传递件7连接所述运动部件3和所述驱动机构5以使得所述驱动机构5通过驱动所述传递件7运动以带动所述运动部件3在所述腔体1内往复运动。
在本实施例中，所述第二腔壁13上设有泄露孔131，所述泄露孔131沿所述运动部件3的运动方向贯穿所述第二腔壁13。
所述驱动机构5包括传动组件51和电机53，所述电机53通过所述传动组件51与所述传递件7连接，其中，所述传动组件51可以为偏心传动结构、凸轮、滚珠丝杠中的任一种。
在本实施例中，所述传动组件51为偏心传动结构。所述传动组件51包括传动连接的偏心部件511和连杆513，所述偏心部件511与所述电机53连接，所述连杆513与所述传递件7连接。
动态压力发生装置工作时，所述吸附口83放置于人体需要按摩的部位，所述电机53依次通过所述偏心部件511、所述连杆513及所述传递件7驱动所述运动部件3在所述腔体1内往复运动，从而使得所述吸附口83处产生周期性交替的正压和负压，从而可以达到吸附放松的效果。
根据需要，所述气道81内径小于开口1A直径，这样可以在负压或正负时，在所述气道81形成快速气流，从而能产生更好的按摩效果。所述气道81采用圆柱形结构。所述吸附口83从靠近气道81一端向外逐渐增大，这样可以在按摩时可以更好的舒适性。
如图3所示，本发明还提供一种动态压力发生装置的第二实施例，其中实施二与实施例一的区别仅在于：所述运动部件3朝向所述开口1A的一侧设有多个按摩凸起9，所述按摩凸起9至少部分可伸出所述吸附口83。具体地，所述运动部件3向靠近所述开口1A的方向运动至最大位置处时，所述按摩凸起9至少部分可伸出所述吸附口83，从而使得所述按摩凸起9可以对人体进行按摩以提高用户体验效果。
需要说明的是，所述驱动机构5的结构并不局限于实施例一和实施例二所述的结构，例如，所述驱动机构也可以为电磁驱动器，电磁驱动器包括第一磁性件以及与所述传递件连接的第二磁性件，其中，所述第一磁性件和所述第二磁性件中的其中一方包括线圈，另一方为磁体，当所述线圈通电时，所述第一磁性件和所述第二磁性件之间的相互作用力可驱动所述运动部件往复运动。
其中，磁体可以为永磁体，也可以为电磁铁。
如图4-图7所示，本发明还提供一种动态压力发生装置的第三实施例。
该动态压力发生装置，包括设有腔室60的内套筒6和设于腔室60的运动部件3，以及驱动运动部件3沿腔室60作直线往复运的驱动机构，该内套筒6设有与腔室60连通的开口61，所述内套筒6外套有弹性材质的外套筒5，该外套筒5设有与开口61连通的外套筒开口51。其中，内套筒6的形状可以是圆筒状，也可以是方形或其他形状的筒状结构。
具体地说，所述运动部件3包括设有自由端3A和驱动端3B的活塞31，在活塞31的自由端3A设有空腔33。所述活塞31的驱动端3B设有沿运动方向延伸的传输部件32。所述驱动机构包括电机1和设于电机转轴(附图未标示)的偏心部件2，该偏心部件2通过连杆4与传输部件32活动连接，所述连杆4与传输部件32和偏心部件4之间分别设有轴承8，该轴承8通过螺丝9与偏心部件4固定实现与偏心部件4稳定配合转动，另一轴承8也是通过另一螺丝9与传输部件32上的固定突起（附图未标示）固定，实现与传输部件32稳定配合转动。
所述内套筒6与运动部件3之间设有配合间隙10，通过试验该配合间隙10不大于0.1MM，才能在外套筒开口51和内套筒开口61处产生动态压力，即在外套筒开口51和内套筒开口61负压，否则无法产生动态压力，即在腔室60内产生变化压力,该配合间隙10最好为小于0.05MM时，效果最好。所述运动部件3采用活塞时，在活塞外套有套环7，此时配合间隙10位于套环7与内套筒6之间，即套环7的外壁与内套筒6的内壁间隔形成间隙10，该套环7由金属材质制成，优选由铝制成。通过配合间隙10较小的配合间隙，可以避免在使用时产生较大噪音，从而实现降低噪音目的。根据需要，所述运动部件3在靠近驱动端3B的位置，即靠近活塞31的驱动端3B的位置，设有对套环7进行定位的限位台阶（附图未示）。
使用时，由驱动机构使运动部件3如活塞31在内套筒6内沿其长度方向往复运动，当外套筒5的开口51处于封闭状态时，通过活塞31往复运动可以改变内套筒6形成的腔室体积，从而使其内气压处于动态变化。由于配合间隙10不大于0.1MM，既能在运动部件3作往复运动时在腔室60内产生压力变化，即产生动态压力，并能在负压内套筒6的开口61处产生负压，运动部件3与腔室60间既可以产生负压，又可以减少产生动态压力变化时的阻力。
在内套筒6外设有弹性外套筒5，一方面可以减少振动向外传递，另一方面也能减小活塞31运动时与内套筒6间接触发生噪音向外传输，从而可以达到减少噪音的目的。
在本实施例中，所述弹性材料包括硅胶，也可以采用其他能吸收噪音或减少噪音传递材料。所述内套筒6采用现有金属材料，如铜质等。
所述活塞31的自由端3A设有空腔33，空腔33可以扩大腔室60的空间，使得动态压力发生装置能在有较大压力变化范围和较大压力变化空间。同时，空腔33还能增加运动部件3与腔室60内空气的接触面积，使运动部件3在运动过程中受力均匀，从而达到平稳运动的目的。
如图8所示，所述外套筒5两端设有向腔室60方向延伸的挡块50，两个挡块50形成收纳内套筒6的收纳腔（附图未标示），内套筒6外形成外套筒5包覆效果，能进一步降低噪音。
如图9所示，所述外套筒5设与内套筒6之间至少在中间部分设有隔音室11。该隔音室11可以减少活塞31往复运动时振动等产生的噪声向外传播，从而能进一步提高降噪效果。根据需要，所述隔音室11最好为真空，其隔间降噪的效果更好。
如图10和图11所示，本发明还提供动态压力发生装置的第四实施例。该动态压力发生装置与上述实施例的区别在于，将第三实施例中的套环7与活塞31做成一体结构，即运动部件3为一体结构，运动部件3的材质为塑料，优选地，运动部件3通过注塑一体成型，其他结构与第一实施例相同，故不再赘述。本发明提供了一种按摩器的实施例，其中，该按摩器包括壳体和设于壳体内的动态压力发生装置，所述动态压力发生装置采用上述实施例结构，不再赘述。
根据需要，所述按摩器还包括控制动态压力发生装置压力连续变化的控制电路和为控制电路和动态压力发生装置供电的电源。
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。
