附图说明
为了更清楚地说明本实用新型实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本实用新型中记载的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1为本实用新型的出液头一实施例的的剖面图，其中，连接件为一塞体；
图2为本实用新型的出液头另一实施例的的剖面图，其中，连接件为一套体。
具体实施方式
下面将结合本实用新型实施例中的附图，对本实用新型实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本实用新型一部分实施例，而不是全部的实施例。基于本实用新型中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本实用新型保护的范围。
如图1、2所示，本实用新型的出液头包括：杯体1、活塞2、推杆3、连接件4以及纳米晶片5。
所述纳米晶片5表面具有一系列微针阵列，它们可以打开皮肤最外面的角质层，同时不会伤及真皮层，以提高药液的渗透能力。所述纳米晶片5连 接于所述连接件4的端面上，为了实现纳米晶片5与活塞2之间的连接，所述连接件4一体注塑成型而成，此时纳米晶片5随所述连接件4的注塑成型一同嵌入于其中。相应的，所述连接件4的材质为橡胶。
所述连接件4是用于将纳米晶片5拆卸地固定于所述活塞2上，以使得活塞2能够带动软胶上的纳米晶片5进行工作的部件。
具体地，所述纳米晶片5连接于所述连接件4的端面上，并通过所述连接件4拆卸地固定于所述活塞2上。所述连接件4可以为一塞体或者套体。从而，当为塞体时，所述连接件4通过塞入的方式拆卸地固定于所述活塞上，当为套体时，所述连接件4通过套装的方式拆卸地固定于所述活塞上。如此设置，当连接件4及其上的纳米晶片5需要置换时，仅需要将连接件4取下，更换新的配件即可，避免了出液头的整体抛弃，其具有使用方便、可重复使用的优点。
所述杯体1的一端开口，所述活塞2收容于所述杯体1中，所述活塞2与所述杯体1共同限定药液的储液空间。由于本实用新型的出液头是应用于一能够震动的按摩仪器的头部上的，为了方便所述出液头与按摩仪器之间的连接，所述杯体1的另一端还连接有接头11，该接头11是用于实现本实用新型的出液头连接于相应按摩仪器上的部件。所述接头11可以为螺纹接头或者卡扣接头。
所述活塞2能够沿所述杯体1的轴向进行往复运动，如此设置，在活塞2的带动下，所述纳米晶片5能够随所述活塞2的轴向运动自所述开口中选择性伸出，以实现纳米晶片5对人皮角质层的穿刺。如此设置，本实用新型的出液头在使用过程中，还具有避免划伤人体皮肤的优点。因为，上述按摩仪 器使用时，是利用其出液头在人体皮肤上摩擦，出液头上的纳米晶片5作用于人体皮肤，打开皮肤最外面的角质层，以便于药液的吸收。当在一个时间点下，纳米晶片5处于与人皮皮肤相接触或者相分离的状态，从而不会沿人体皮肤进滑动。同时，所述活塞2收容于所述杯体1中时，所述活塞2的周向外壁面贴合于所述杯体1的周向内壁面，以形成上述储液空间。
为了实现所述活塞2的轴向往复运动，所述推杆3一端沿所述杯体1的另一端轴向活动地伸入所述杯体1中，并与所述活塞2的另一端相连接。从而，活动的推杆3可带动所述活塞2进行轴向往复运动。此时，所述推杆3贯穿所述螺纹接头轴向活动地伸入所述杯体1中
为了实现所述推杆3与杯体1之间的连接，所述推杆3一端以插接方式与所述活塞2的另一端相连接。此时，插入所述活塞2的推杆3上还设置有与所述活塞2卡合的卡扣31，以防止推杆3与活塞2之间发生松脱。
所述杯体1的另一端还连接有导向套12，所述推杆3于所述导向套12内部轴向活动，如此设置，能够方便所述推杆3推动活塞2进行轴向往复运动。同时，为了限制所述推杆3轴向的运动行程，位于所述杯体1外部的所述推杆3的周向壁面上设置有限位凸起32，当该限位凸起32抵靠于所述杯体1时，推杆3到达极限形成位置。
为了实现本实用新型的间歇式给药的目的，所述活塞2的周向壁面上开设有内出液孔21，所述杯体1的周向壁面上开设有外出液孔13。从而，所述内出液孔21与外出液孔13随所述活塞2的轴向运动选择性对齐连通，即随着推杆3的运动，当所述内出液孔21与外出液孔13对齐连通，出液空间中的药液可依次通过内出液孔21和外出液孔13流出，以此实现打开皮肤最外 面的角质层的同时进行给药的效果。优选地，所述内出液孔21与外出液孔13同轴对齐连通时，所述活塞2的另一端与所述杯体1的底部相抵靠，此时对应出液通道具有最大的口径。
综上所述，本实用新型的出液头通过设置内出液孔以及能够选择性与内出液孔对齐连通的外出液孔，实现了出液头的间歇式给药，满足了使用者的实际使用需求。
对于本领域技术人员而言，显然本实用新型不限于上述示范性实施例的细节，而且在不背离本实用新型的精神或基本特征的情况下，能够以其他的具体形式实现本实用新型。因此，无论从哪一点来看，均应将实施例看作是示范性的，而且是非限制性的，本实用新型的范围由所附权利要求而不是上述说明限定，因此旨在将落在权利要求的等同要件的含义和范围内的所有变化囊括在本实用新型内。不应将权利要求中的任何附图标记视为限制所涉及的权利要求。
此外，应当理解，虽然本说明书按照实施方式加以描述，但并非每个实施方式仅包含一个独立的技术方案，说明书的这种叙述方式仅仅是为清楚起见，本领域技术人员应当将说明书作为一个整体，各实施例中的技术方案也可以经适当组合，形成本领域技术人员可以理解的其他实施方式。
