请参阅图1至图6，示出了本申请实施例公开一种按摩头100，包括：
安装座1，该安装座1为柔性安装座，即安装座1采用柔性材料构成，安装座1具有环形槽11，且安装座1中设有电子元件(图未示出)，电子元件位于环形槽11的内侧；
金属电极片2，金属电极片包括相背设置的工作面21和背面22，工作面21为远离环形槽11的一面，背面22为朝向环形槽11的一面，背面22上具有环形插接部23(即图4中背面朝上具有环形插接部23)，环形插接部23固定插设在环形槽11中，使环形槽11包裹环形插接部23。
本申请实施例中，安装座1本身采用柔性材料构成，安装座1朝自身内部凹陷(即图3中安装座1向上内凹)形成有环形槽11，金属电极片2的背面22上则具有环形插接部23，通过环形插接部23与环形槽11的固定插接配合，可以使柔性材料构成的环形槽11包裹在环形插接部23的外周。如此设置，由于环形槽11为柔性材料，利用环形槽11包裹金属电极片2的环形插接部23时，能够有效减小环形槽11与环形插接部23之间的间隙，从而因环形槽11的包裹设置，而使按摩头100具有良好的防水密封性能。这样的密封性可以很好的防止液体渗入到安装座内部，对于设在安装座1中且位于环形槽11内侧的电子元件而言，这能避免因液体渗入而导致电子元件短路失效的情况出现，延长按摩头的使用寿命。
需要说明的是，在本申请实施例中，柔性材料是指材质较柔软且同时又具有一定结构强度、可作为基座结构使用的材料，例如硅胶、橡胶、TPE等材料，其中TPE为热塑性弹性体(Thermoplastic Elastomer，TPE)。具体在本实施例中，优选可采用硅胶座作为安装座。
其中，安装座1中的电子元件可以是EMS电连接线、发热件或热敏元件的一种或者多种，利用这些电子元件与金属电极片进行配合使用，能够使金属电极片实现EMS(Electric Muscle Stimulation，肌肉电刺激)按摩、热敷等按摩功能。具体地，电子元件包括EMS电连接线时，EMS电连接线至少有一部分位于环形槽的内侧并与金属电极片2焊接，金属电极片2则能够提供EMS(肌肉电刺激)按摩，通过向待按摩部位施加脉冲电流，从而加快待按摩部位肌肉处的血液循环，有效地对肌肉形成舒缓的作用。
作为可选的实施方式，环形插接部23可以通过多种固定连接方式固定插设在环形槽11中。例如，可以在环形插接部插入至环形槽中后，通过在环形插接部与环形槽之间增设螺柱与螺帽的配合、或者是按扣的卡扣配合来进一步固定环形插接部与环形槽的固定连接关系。具体在本申请实施例中，优选采用胶粘方式来固定粘接环形插接部。通过胶粘方式将环形插接部23固定粘接在环形槽11中，一方面可以增强环形插接部23与环形槽11之间的密封防水效果，加强环形槽11 对环形插接部23的包裹作用；另一方面可使得金属电极片2与安装座1之间的安装关系更稳固牢靠，且胶粘固定操作难度低，在无需引入其他固定结构的情况下，利于简化金属电极片2与安装座1之间的装配操作。
请具体参阅图3和图4，在本申请实施例中，环形槽11设置在安装座1的周沿，环形插接部23位于金属电极片2的背面22的内侧、从靠近背面22的边缘处朝安装座1的方向延伸形成。作为其他可选的实施方式，环形插接部也可以直接是金属电极片朝向环形槽的方向设置的翻边。
采用上述结构，将环形槽11尽可能设置在安装座1的周沿，对应地，环形插接部23也尽可能的设置在金属电极片2的边缘或者边缘附近，这样在环形插接部23与环形槽11插接装配时，有利于使整体结构更加稳定。
此外，当环形插接部23采用如图4所示的结构设置，环形插接部23设于背面2的内侧且靠近金属电极片2的边缘设置时，在环形插接部23与金属电极片2的边缘之间还形成有一圈外边框24。当环形插接部23固定插设到环形槽11中，结合图1和图2所示，这一圈外边框24会形成用于防止液体渗入环形槽11的阻挡边框，从而进一步加强按摩头100的防水效果。具体是，当在金属电极片2上涂抹液体时，液体不会直接接触到环形槽11，而是要先流经外边框24、再流至环形槽11，这一液体流经过程使得液体经过外边框23的阻挡后、较难流至环形槽11，从而有利于加强按摩头的防水效果。尤其是当外边框24与安装座1之间采用胶粘固定粘接时，液体更难从外边框24渗入至环形槽11处。
当环形插接部为金属电极片的翻边时，该翻边包裹在柔性材料构成的环形槽中。由于金属电极片中的翻边有可能是利边，将翻边包裹在柔性的环形槽中也就是对利边进行包裹，这样可以避免利边刮伤用户身体部位的风险。
进一步地，金属电极片还包括连接在翻边和金属电极片的工作面之间的过渡部，利用过渡部来过渡连接翻边和金属电极片的工作面，能够进一步降低因金属电极片的锐利结构部分给用户身体部位带来刮伤的风险。作为一些可选的实施方式，可以将过渡部的外表面设置为弧面或者斜面，以起到更好的防护作用、避免刮伤用户。此外，通过将翻边包裹在环形槽中的设置，还使金属电极片的边缘位于安装座的内侧，也即金属电极片的边缘小于安装座的边缘，这样用户使用按摩头过程中，接触到位于外侧的安装座时，硅胶座等按摩座因具有质地柔软的特点，故用户接触到安装座也不会产生硌硬感，可提高用户使用按摩头的舒适感。
作为其他可选的实施方式，环形槽也可以不在安装座的周沿、而是更靠近安装座的中心方向设置，同样地，环形插接部也可以更靠近金属电极片的中心设置，仍然可以实现环形插接部与环形槽的插接配合。
请具体参阅图5和图6，为了进一步提高金属电极片与安装座之间装配关系的稳定性，本申请实施例将环形槽11设置为斜槽，环形槽11的槽底靠近安装座1的中轴线设置，环形槽11的槽口远离安装座1的中轴线设置。其中，安装座1 的中轴线是指位于安装座1中部且垂直于安装座1的安装面的轴线，即图5中位于安装座1中部且大致沿斜向的上下方向延伸的轴线。采用上述的斜槽，也即，将环形槽11的倾斜方向设置为从槽口至槽底逐渐向内收缩，这种斜槽设计，一方面有利于增大环形插接部23与环形槽11之间的固定连接面积，尤其是环形插接部23与环形槽11之间为胶粘固接时，有利于增大二者之间的粘接面积，可以使二者的粘接固定更加牢固，进而使金属电极片2与安装座1的装配关系更稳定；另一方面，金属电极片2的环形插接部23能够与该环形槽11实现过盈插接，二者之间形成向内逐渐倾斜设置的结合面，同样有利于提高二者之间连接关系的稳定性。
作为一些可选的实施方式，本申请实施例中环形槽的形状，既可以设置成如图5和图6中所示的，环形槽沿轴线方向的截面形状大致呈矩形；也可以设置成其他形状，例如图7中所示的，环形槽沿轴线方向的截面形状为内侧槽壁和外侧槽壁设置成波浪形的形状，对应地，金属电极片的环形插接部也设置成波浪形，采用该形状也能够将环形插接部顺利地插设到环形槽中，而且采用该形状时环形插接部与环形槽的接触面积更大、更有利于二者之间的装配连接稳定性、牢固性。
需要说明的是，在本申请实施例中，安装座的轴线是指沿垂直于安装座的安装面的轴线，安装座的中轴线是位于安装座中部的轴线，安装座的安装面是设有环形槽的一面，也即安装座沿径向方向的一面。
请参阅回图3，安装座1沿自身的轴线方向具有一定厚度L，且3mm≤L≤7mm。本申请实施例中，安装座1沿轴线方向的厚度也即图N中安装座1沿上下方向的厚度。在该厚度范围内，采用柔性材料构成的安装座1能够保持一定的结构形状，并且具有一定结构强度，可以对金属电极片起到结构支撑的作用。若厚度L小于3mm，容易造成安装座1的撕裂；若厚度L大于3mm，一方面是会增加生产成本，另一方面会减弱安装座本身具有的柔性形变量、降低安装座在用于按摩时对于按摩振动的调节能力。作为可选的实施方式，厚度L可以为3mm、3.5mm、4mm、4.5mm、5mm、5.5mm、6mm、6.5mm或7mm。
在本申请实施例中，金属电极片2的工作面与所述环形槽11的端面齐平；或者，金属电极片2的工作面凸出于环形槽11的端面，且凸出的高度范围为0.3mm-2.5mm。将金属电极片2的工作面设置为不低于环形槽11的端面，能够保证用户在使用按摩头100时，身体的待按摩部位可以有效接触到金属电极片2、与金属电极片2进行贴合。本申请实施例优选采用金属电极片2的工作面凸出于环形槽11的端面的设置方式，使凸出高度范围在0.3mm-2.5mm之间。若凸出高度范围大于2.5mm，考虑到金属电极片2的厚度有限，则较大的凸出高度可能会影响金属电极片2与安装座1的内部结构之间的装配效果。作为可选的实施方式，凸出的高度可以为0.3mm、0.5mm、0.8mm、1.0mm、1.5mm、1.8mm、2.0mm、2.3mm或2.5mm。
在本申请实施例中，安装座1靠近金属电极片2的外表面设置为倒圆角形状，请参阅图6，该安装座1靠近金属电极片2的外表面也对应于环形槽11的外槽体111，这样可以使安装座1的外表面更加平滑圆润，不存在利边，使用户的待按摩部位接触到安装座时，触感更好、不会有硌硬感。
请一并参阅图3至图8，为了更进一步提高金属电极片与安装座之间的装配稳定性，在安装座1的内部形成有朝金属电极片2方向凸出(即图8中安装座1朝纸面向外的方向凸出)的凸台12，凸台12与金属电极片2的背面22抵接且粘接固定，凸台12的外侧壁形成为环形槽11的内侧槽壁。在本申请实施例中，利用凸台12与金属电极片2的背面22之间抵接并且粘接固定，可以进一步增加金属电极片2与安装座1之间的粘接面积，利于提高金属电极片2与安装座1之间的固定连接稳定性。尤其是凸台12的外侧壁形成为环形槽11的内侧槽壁，也就是说凸台12与环形槽11邻近设置，这样，环形插接部与环形槽之间的固定插接，结合金属电极片背面与凸台表面之间的抵接与粘接，可以共同作用以提高金属电极片与安装座之间的装配稳定性，尤其是环形插接部与环形槽也通过胶粘固定时，既方便金属电极片与环形槽之间的装配、又能保证二者装配的稳定性。
本申请实施例中，在安装座1的径向方向上，凸台12沿安装座1径向方向的宽度为D，1mm≤D≤3mm，保持该宽度，有利于凸台12对环形插接部23提供足够的支撑强度。若D小于1mm，凸台12在径向上的宽度过小，其结构强度不足以形成对环形插接部23的有力支撑，金属电极片2容易从环形槽11中松动脱离；若D大于3mm，则不利于在凸台12中间挖空设置可以容置其他结构的避让空间。作为可选的实施方式，凸台12沿安装座1径向方向的宽度D可以为1mm、1.5mm、1.8mm、2mm、2.2mm、2.5mm、2.8mm或3mm。
在本申请实施例中，采用胶粘固定连接环形插接部23和环形槽11、或者同时还采用胶粘固定金属电极片2与凸台12相对设置的表面，是对金属电极片2与安装座1进行方便、稳定装配的较佳方式。但采用胶粘固定就意味着需要在待粘接的部位使用过量的胶黏剂，以胶粘固定环形插接部23和环形槽11为例，需要在环形槽11处涂覆过量的胶水，由此来保证环形插接部23和环形槽11的良好粘接效果。对于金属电极片2与凸台12的相对表面的粘接，也同样需要涂覆过量的胶黏剂。为了避免因过量的胶水无处容置而导致粘接面的胶黏剂薄厚不均、金属电极片贴合后表面不平整等问题，本申请实施例还提供溢胶结构，给过量的胶黏剂提供一定的挤压释放空间。
作为一种可选的实施方式，请参阅图9，环形槽11的内侧槽壁112沿安装座1的径向向外凸出形成台阶体41，环形插接部23通过胶粘固定插设在环形槽11中时，台阶体41用于为过量的胶黏剂提供容置空间。在本申请实施例中，在安装槽车11的槽口处形成该台阶体41，由于是在环形槽11的基础上提供更多的容置空间，故金属电极片2粘接在环形槽11中时，过量的胶黏剂可以被挤压到该 台阶体41上，使台阶体41提供一定的溢胶容置空间，由此来防止因胶水厚度涂抹不均匀导致电极片贴合后不平整的问题，减少装配误差。
此外，设置该台阶体41还能对金属电极片2的安装起到导向的作用。本申请实施例的环形插接部23，其内侧面的根部采用圆角的弧形设置，这就要求安装座1中设置凸台12时，需要将凸台12的四个角部也设置成与环形插接部23相匹配的圆角，否则金属电极片2在环形槽11中的装配会比较困难。然而，在环形槽11的内侧槽壁112形成该台阶体41，也就是在凸台12的外壁面形成该台阶体41，由于台阶体41的设置，使得金属电极片2与凸台12之间具有一定间距，此时凸台12的四个角部无论是设置成圆角、还是设置成直角，都不会对金属电极片2在环形槽11中的装配产生干扰，由此可以降低对凸台12的结构设计要求，也可以减少金属电极片2的装配误差。
作为另一种可选的实施方式，凸台也可以朝自身内凹形成溢胶槽(图未示出)；环形插接部通过胶粘固定插设在环形槽中时，溢胶槽用于为过量的胶黏剂提供容置空间。本申请实施例，通过在凸台上设置专门的溢胶槽，能够在环形插接部插入至环形槽中时，金属电极片与凸台的相对表面进行粘接时，将过量的胶黏剂从环形槽中溢出至溢胶槽进行容置。由于溢胶槽能够为过量的胶黏剂提供预留的挤压释放空间，故能够防止因胶黏剂厚度涂抹不均匀导致金属电极片贴合后的表面不平整问题，进而减少装配误差。此外，设置溢胶槽还能够避免过量的胶黏剂直接溢流至安装座内部的情况出现。
进一步地，该溢胶槽靠近环形槽设置，更方便来自环形槽的过量胶黏剂溢流至溢胶槽中。在金属电极片与安装座的装配连接中，环形插接部与环形槽的粘接固定是尤为重要的，因此在二者的连接处设置的胶黏剂也较多，将溢胶槽靠近环形槽设置，利于快速收集从环形槽中溢出的多余胶黏剂。
为同时兼顾溢胶效果以及安装座与金属电极片之间的结构强度，溢胶槽的槽体深度小于或者等于环形槽的槽体深度，同时，溢胶槽的槽体深度小于或者等于3mm。若溢胶槽的槽体深度过深，例如大于环形槽的槽体深度或者大于3mm，容易导致凸台被挖空较多，此时凸台靠近金属电极片的一侧结构强度变弱，可能无法为环形插接部提供足够的支撑力度。在一些可选的实施方式中，溢胶槽的槽体深度可以为3mm、2.8mm、2.5mm、2.2mm、2mm、1.5mm、1mm或0.8mm。
作为又一种可选的实施方式，还可以同时设置上述两种溢胶结构，给过量的胶黏剂提供更多的挤压释放空间。也就是说，在本申请实施例中，既从环形槽的内侧槽壁沿安装座的径向向外凸出形成台阶体，利用多出来的台阶空间来提供溢胶空间；又使凸台朝自身内凹形成溢胶槽，利用溢胶槽的槽体来提供溢胶空间。
为了使按摩头100具有更多功能，按摩头100还包括发热件3，发热件3固设在金属电极片2的背面22(即图4中发热件3固设在金属电极片3的上表面)，凸台12朝自身内凹(即图3中凸台12朝纸面向里的方向内凹)形成避位空间， 发热件3容置于避位空间中，安装座1用于形成避位空间的柔性材料采用热的不良导体材料。
在本申请实施例中，通过在金属电极片2上固设发热件3，可以利用发热件3对金属电极片2进行加热，提升按摩效果。此外为了提高加热效率，在凸台12上对应于设有发热件3的位置处形成避位空间，在金属电极片2的表面与凸台12的表面抵接且粘接时，金属电极片2与凸台12相抵接的表面与避位空间共同围合形成了封闭或者非封闭的腔室，发热件3容置在这个腔室中时，其散发的热量能够通过该腔室集中传递。尤其是本申请实施例中安装座用于形成避位空间的柔性材料采用的是热的不良导体材料，例如安装座为硅胶座，硅胶就是热的不良导体，这使得发热件3的热量与避位空间进行热交换的损失较小，发热件3的热量更多的传递到金属电极片2上，从而提高热传递效率。
其中，发热件3除了可以固设在金属电极片2的背面22，也可以采用其他安装设置方式。例如发热件3也可以不固设在金属电极片2的背面22，而是固设在避位空间的侧壁或底壁中，又如发热件3还可以是仅容置在避位空间中，既不与金属电极片2的背面22固接、也不与避位空间上的结构固接，实际上只要发热件3容置在该避位空间中，其加热工作时就能够向金属电极片2传热，故在此不对发热件3的固定安装进行限制。
在本申请实施例中，发热件3具体是固设在金属电极片2上的发热丝31，避位空间是凸台内凹形成的容纳槽13，发热丝31容置在容纳槽中13。在金属电极片2的表面与凸台12的表面抵接且粘接时，金属电极片2与凸台12相抵接的表面与容纳槽13共同围合形成了封闭的腔室，发热件3容置在这个腔室中时，其散发的热量能够通过该腔室集中传递。尤其是安装座为硅胶座，容纳槽13为硅胶容纳槽，该硅胶容纳槽导热性能不良，故使得发热丝31发出的热量损失较小，可以更多更集中地传递至金属电极片2。
请参阅图8，安装座1沿自身轴线方向设有过线孔14，容纳槽13中设有连通于过线孔14的避让缺口15；发热丝31包括发热部311以及与发热部311相连的电连接线312，发热部311、发热部311与电连接线312的连接端均容置在容纳槽13中，电连接线312穿设在避让缺口15和过线孔14中。在本申请实施例中，通过设置过线孔14以及避让缺口15，来方便发热丝31的走线，以实现发热丝31与外部结构的电连接。同时，为了避免因发热丝31的走线空间设置不合理而影响金属电极片2与凸台12之间的抵接贴合设置效果，具体是在容纳槽13中设置避让缺口15、在安装座中部设置过线孔14的同时，还将发热丝的发热部311、发热部311与电连接线312的连接端均设置在容纳槽13中，这样的结构设置，为所有的走线都预留了避让的空间，因此虽然对电连接线312与外部结构进行电连接走线设置，但仍然能够保持金属电极片2与凸台12之间的抵接贴合具有良好的平整度。
具体地，请参阅图4和图8，按摩头100用于安装在带有主机的按摩仪(图未示出)上，避让缺口15包括分别连通于过线孔14的第一避让缺口15a和第二避让缺口15b，电连接线312包括分别设置在发热部311两端的第一电连接线312a和第二电连接线312b，第一电连接线312a穿设在第一避让缺口15a和过线孔14中，第二电连接线312b穿设在第二避让缺口15b和过线孔14中，第一电连接线312a和第二电连接线312b分别与主机电连接。在容纳槽13的内壁上设置两个彼此独立的第一避让缺口15a和第二避让缺口15b，可用于使发热丝31的第一电连接线312a和第二电连接线312b分别穿过、且不接触，以避免两个电连接线接触短路。
在本申请实施例中，发热丝31既可以设置成环绕的一圈发热丝，也可以设置承诺环绕多圈的发热丝，都可起到良好的发热功能，尤其是设置成环绕的多圈发热丝时，其具有更好的发热效果。此外，发热丝31优选靠近金属电极片2的边缘设置。实际上，只要发热丝31固设在金属电极片2上，就能将热量传递给金属电极片2，但发热丝31越靠近金属电极片2的边缘设置，发热丝的总长度就越长，进而可以使发热丝的发热速率更快，使金属电极片的升温速度更快。
请参阅图8，容纳槽13将凸台12分为第一凸台121和第二凸台122，第一凸台121为靠近环形槽11的外凸台，第二凸台122为远离环形槽11的内凸台，且第二凸台122位于第一凸台121的内部。其中，在安装座1的径向方向上，第一凸台121沿安装座1径向方向的宽度为D，1mm≤D≤3mm。若D小于1mm，第一凸台在径向上的宽度过小，其结构强度不足以形成对环形插接部23的有力支撑，金属电极片2容易从环形槽11中松动脱离；若D大于3mm，第一凸台在径向上的宽度过大，这会导致用于容置发热丝31的容纳槽13只能更靠近安装座1的中心设置，进而导致发热丝13可设置的长度过小，影响发热丝13的发热速率以及金属电极片2的升温速率，最终导致按摩头100的热敷功能出现明显的延时问题。作为可选的实施方式，第一凸台121沿安装座1径向方向的宽度D可以为1mm、1.5mm、1.8mm、2mm、2.2mm、2.5mm、2.8mm或3mm。
请参阅图10至图15，是本申请实施例的另一种按摩头，本申请实施例公开一种按摩头100，包括：
安装座1，该安装座1为柔性安装座，即安装座1采用柔性材料构成，安装座1具有环形槽11，且安装座1中设有电子元件(图未示出)，电子元件位于环形槽11的内侧；
金属电极片2，金属电极片包括相背设置的工作面21和背面22，工作面21为远离环形槽11的一面，背面22为朝向环形槽11的一面，背面22上具有环形插接部23(即图13中背面朝上具有环形插接部23)，环形插接部23固定插设在环形槽11中，使环形槽11包裹环形插接部23。
本申请实施例中，安装座1本身采用柔性材料构成，安装座1朝自身内部凹 陷(即图12中安装座1朝向纸面里的方向内凹)形成有环形槽11，金属电极片2的背面22上则具有环形插接部23，通过环形插接部23与环形槽11的固定插接配合，可以使柔性材料构成的环形槽11包裹在环形插接部23的外周。如此设置，由于环形槽11为柔性材料，利用环形槽11包裹金属电极片2的环形插接部23时，能够有效减小环形槽11与环形插接部23之间的间隙，从而因环形槽11的包裹设置，而使按摩头100具有良好的防水密封性能。这样的密封性可以很好的防止液体渗入到安装座内部，对于设在安装座1中且位于环形槽11内侧的电子元件而言，这能避免因液体渗入而导致电子元件短路失效的情况出现，延长按摩头的使用寿命。
需要说明的是，在本申请实施例中，柔性材料是指材质较柔软且同时又具有一定结构强度、可作为基座结构使用的材料，例如硅胶、橡胶、TPE等材料，其中TPE为热塑性柔性体(Thermoplastic Elastomer，TPE)。具体在本实施例中，优选可采用硅胶座作为安装座。
其中，安装座1中的电子元件可以是EMS电连接线、发热件和热敏元件的一种或者多种，利用这些电子元件与金属电极片进行配合使用，能够使金属电极片实现EMS(Electric Muscle Stimulation，肌肉电刺激)按摩、热敷等按摩功能。具体地，电子元件包括EMS电连接线时，EMS电连接线至少有一部分位于环形槽的内侧并与金属电极片2焊接，金属电极片2则能够提供EMS(肌肉电刺激)按摩，通过向待按摩部位施加脉冲电流，从而加快待按摩部位肌肉处的血液循环，有效地对肌肉形成舒缓的作用。
作为可选的实施方式，环形插接部23可以通过多种固定连接方式固定插设在环形槽11中。例如，可以在环形插接部插入至环形槽中后，通过在环形插接部与环形槽之间增设螺柱与螺帽的配合、或者是按扣的卡扣配合来进一步固定环形插接部与环形槽的固定连接关系。具体在本申请实施例中，优选采用胶粘方式来固定粘接环形插接部。通过胶粘方式将环形插接部23固定粘接在环形槽11中，一方面可以增强环形插接部23与环形槽11之间的密封防水效果，加强环形槽11对环形插接部23的包裹作用；另一方面可使得金属电极片2与安装座1之间的安装关系更稳固牢靠，且胶粘固定操作难度低，在无需引入其他固定结构的情况下，利于简化金属电极片2与安装座1之间的装配操作。
请具体参阅图10和图11，在本申请实施例中，环形槽11设置在安装座1的周沿，环形插接部23从金属电极片2的背面22的边缘朝安装座1的方向向上延伸形成，环形插接部23即为金属电极片2的翻边。作为其他可选的实施方式，环形插接部也可以位于背面的内侧、从靠近背面的边缘处朝安装座的方向延伸形成。
采用上述结构，将环形槽11尽可能设置在安装座1的周沿，对应地，环形插接部23也尽可能的设置在金属电极片2的边缘或者边缘附近，这样在环形插 接部23与环形槽11插接装配时，有利于使整体结构更加稳定。
此外，当环形插接部23采用如图11所示的结构设置时，环形插接部23为金属电极片2的翻边，该翻边包裹在柔性材料构成的环形槽11中。由于金属电极片中的翻边有可能是利边，将翻边包裹在柔性的环形槽11中也就是对利边进行包裹，这样可以避免利边刮伤用户身体部位的风险。
进一步地，金属电极片2还包括连接在翻边和金属电极片的工作面21之间的过渡部25，利用过渡部25来过渡连接翻边和金属电极片的工作面21，能够进一步降低因金属电极片2的锐利结构部分给用户身体部位带来刮伤的风险。作为一些可选的实施方式，可以将过渡部25的外表面设置为弧面或者斜面，以起到更好的防护作用、避免刮伤用户。此外，通过将翻边包裹在环形槽中的设置，还使金属电极片的边缘位于安装座的内侧，也即金属电极片的边缘小于安装座的边缘，这样用户使用按摩头过程中，接触到位于外侧的安装座时，硅胶座等按摩座因具有质地柔软的特点，故用户接触到安装座也不会产生硌硬感，可提高用户使用按摩头的舒适感。
当环形插接部设置在金属电极片的内侧但靠近金属电极片的边缘时，在环形插接部与金属电极片的边缘之间还形成有一圈外边框。当环形插接部固定插设到环形槽中，这一圈外边框会形成用于防止液体渗入环形槽的阻挡边框，从而进一步加强按摩头的防水效果。具体是，当在金属电极片上涂抹液体时，液体不会直接接触到环形槽，而是要先流经外边框、再流至环形槽，这一液体流经过程使得液体经过外边框的阻挡后、较难流至环形槽，从而有利于加强按摩头的防水效果。尤其是当外边框与安装座之间采用胶粘固定粘接时，液体更难从外边框渗入至环形槽处。
作为其他可选的实施方式，环形槽也可以不在安装座的周沿、而是更靠近安装座的中心方向设置，同样地，环形插接部也可以更靠近金属电极片的中心设置，仍然可以实现环形插接部与环形槽的插接配合。
请具体参阅图14和图15，为了进一步提高金属电极片与安装座之间装配关系的稳定性，本申请实施例将环形槽11设置为斜槽，环形槽11的槽底靠近安装座1的中轴线设置，环形槽11的槽口远离安装座1的中轴线设置。其中，安装座1的中轴线是指位于安装座1中部且垂直于安装座1的安装面的轴线，即图14中位于安装座1中部且大致沿斜向的上下方向延伸的轴线。采用上述的斜槽，也即，将环形槽11的倾斜方向设置为从槽口至槽底逐渐向内收缩，这种斜槽设计，一方面有利于增大环形插接部23与环形槽11之间的固定连接面积，尤其是环形插接部23与环形槽11之间为胶粘固接时，有利于增大二者之间的粘接面积，可以使二者的粘接固定更加牢固，进而使金属电极片2与安装座1的装配关系更稳定；另一方面，金属电极片2的环形插接部23能够与该环形槽11实现过盈插接，二者之间形成向内逐渐倾斜设置的结合面，同样有利于提高二者之间连接关系的 稳定性。
作为一些可选的实施方式，本申请实施例中环形槽的形状，既可以设置成如图14和图15中所示的，环形槽沿轴线方向的截面形状大致呈矩形；也可以设置成其他形状，例如环形槽沿轴线方向的截面形状为内侧槽壁和外侧槽壁设置成波浪形的形状，对应地，金属电极片的环形插接部也设置成波浪形，采用该形状也能够将环形插接部顺利地插设到环形槽中，而且采用该形状时环形插接部与环形槽的接触面积更大、更有利于二者之间的装配连接稳定性、牢固性。
需要说明的是，在本申请实施例中，安装座的轴线是指沿垂直于安装座的安装面的轴线，安装座的中轴线是位于安装座中部的轴线，安装座的安装面是设有环形槽的一面，也即安装座沿径向方向的一面。
请参阅回图12，安装座1沿自身的轴线方向具有一定厚度L，且3mm≤L≤7mm。本申请实施例中，安装座1沿轴线方向的厚度也即图N中安装座1沿上下方向的厚度。在该厚度范围内，采用柔性材料构成的安装座1能够保持一定的结构形状，并且具有一定结构强度，可以对金属电极片起到结构支撑的作用。若厚度L小于3mm，容易造成安装座1的撕裂；若厚度L大于3mm，一方面是会增加生产成本，另一方面会减弱安装座本身具有的柔性形变量、降低安装座在用于按摩时对于按摩振动的调节能力。作为可选的实施方式，厚度L可以为3mm、3.5mm、4mm、4.5mm、5mm、5.5mm、6mm、6.5mm或7mm。
在本申请实施例中，金属电极片2的工作面与所述环形槽11的端面齐平；或者，金属电极片2的工作面凸出于环形槽11的端面，且凸出的高度范围为0.3mm-2.5mm。将金属电极片2的工作面设置为不低于环形槽11的端面，能够保证用户在使用按摩头100时，身体的待按摩部位可以有效接触到金属电极片2、与金属电极片2进行贴合。本申请实施例优选采用金属电极片2的工作面凸出于环形槽11的端面的设置方式，使凸出高度范围在0.3mm-2.5mm之间。若凸出高度范围大于2.5mm，考虑到金属电极片2的厚度有限，则较大的凸出高度可能会影响金属电极片2与安装座1的内部结构之间的装配效果。作为可选的实施方式，凸出的高度可以为0.3mm、0.5mm、0.8mm、1.0mm、1.5mm、1.8mm、2.0mm、2.3mm或2.5mm。
在本申请实施例中，安装座1靠近金属电极片2的外表面设置为倒圆角形状，请参阅图15，该安装座1靠近金属电极片2的外表面也对应于环形槽11的外槽体111，这样可以使安装座1的外表面更加平滑圆润，不存在利边，使用户的待按摩部位接触到安装座时，触感更好、不会有硌硬感。
请一并参阅回图12，为了更进一步提高金属电极片与安装座之间的装配稳定性，在安装座1的内部形成有朝金属电极片2方向凸出(即图12中安装座1朝纸面向外的方向凸出)的凸台12，凸台12与金属电极片2的背面22抵接且粘接固定，凸台12的外侧壁形成为环形槽11的内侧槽壁。在本申请实施例中，利用 凸台12与金属电极片2的背面22之间抵接并且粘接固定，可以进一步增加金属电极片2与安装座1之间的粘接面积，利于提高金属电极片2与安装座1之间的固定连接稳定性。尤其是凸台12的外侧壁形成为环形槽11的内侧槽壁，也就是说凸台12与环形槽11邻近设置，这样，环形插接部与环形槽之间的固定插接，结合金属电极片背面与凸台表面之间的抵接与粘接，可以共同作用以提高金属电极片与安装座之间的装配稳定性，尤其是环形插接部与环形槽也通过胶粘固定时，既方便金属电极片与环形槽之间的装配、又能保证二者装配的稳定性。
本申请实施例中，在安装座1的径向方向上，凸台12沿安装座1径向方向的宽度为D，1mm≤D≤3mm，保持该宽度，有利于凸台12对环形插接部23提供足够的支撑强度。若D小于1mm，凸台12在径向上的宽度过小，其结构强度不足以形成对环形插接部23的有力支撑，金属电极片2容易从环形槽11中松动脱离；若D大于3mm，则不利于在凸台12中间挖空设置可以容置其他结构的避让空间。作为可选的实施方式，第一凸台121沿安装座1径向方向的宽度D可以为1mm、1.5mm、1.8mm、2mm、2.2mm、2.5mm、2.8mm或3mm。
在本申请实施例中，采用胶粘固定连接环形插接部23和环形槽11、或者同时还采用胶粘固定金属电极片2与凸台12相对设置的表面，是对金属电极片2与安装座1进行方便、稳定装配的较佳方式。但采用胶粘固定就意味着需要在待粘接的部位使用过量的胶黏剂，以胶粘固定环形插接部23和环形槽11为例，需要在环形槽11处涂覆过量的胶水，由此来保证环形插接部23和环形槽11的良好粘接效果。对于金属电极片2与凸台12的相对表面的粘接，也同样需要涂覆过量的胶黏剂。为了避免因过量的胶水无处容置而导致粘接面的胶黏剂薄厚不均、金属电极片贴合后表面不平整等问题，本申请实施例还提供溢胶结构，给过量的胶水提供一定的挤压释放空间。
作为一种可选的实施方式，请参阅图12，凸台12可以朝自身内凹形成溢胶槽42，环形插接部23通过胶粘固定插设在环形槽11中时，溢胶槽42用于为过量的胶黏剂提供容置空间。本申请实施例，通过在凸台12上设置专门的溢胶槽42，能够在环形插接部12插入至环形槽11中时，金属电极片2与凸台12的相对表面进行粘接时，将过量的胶黏剂从环形槽11中溢出至第二溢流槽42进行容置。由于第二溢流槽42能够为过量的胶黏剂提供预留的挤压释放空间，故能够防止因胶黏剂厚度涂抹不均匀导致金属电极片2贴合后的表面不平整问题，进而减少装配误差。此外，设置第二溢流槽42还能够避免过量的胶黏剂直接溢流至安装座1内部的情况出现。
进一步地，该溢胶槽42靠近环形槽11设置，更方便来自环形槽11的过量胶黏剂溢流至溢胶槽42中。在金属电极片2与安装座1的装配连接中，环形插接部23与环形槽11的粘接固定是尤为重要的，因此在二者的连接处设置的胶黏剂也交多少，将溢胶槽42靠近环形槽11设置，利于快速收集从环形槽11中溢 出的多余胶黏剂。
为同时兼顾溢胶效果以及安装座1与金属电极片2之间的结构强度，溢胶槽42的槽体深度小于或者等于环形槽11的槽体深度，同时，溢胶槽42的槽体深度小于或者等于3mm。若溢胶槽42的槽体深度过深，例如大于环形槽42的槽体深度或者大于3mm，容易导致凸台12被挖空较多，此时凸台12靠近金属电极片2的一侧结构强度变弱，可能无法为环形插接部23提供足够的支撑力度。在一些可选的实施方式中，溢胶槽42的槽体深度可以为3mm、2.8mm、2.5mm、2.2mm、2mm、1.5mm、1mm或0.8mm。
作为另一种可选的实施方式，环形槽的内侧槽壁(也即凸台的外侧壁)沿安装座的径向向外凸出形成台阶体，环形插接部通过胶粘固定插设在环形槽中时，台阶体用于为过量的胶黏剂提供容置空间。在本申请实施例中，在环形槽的槽口处形成该台阶体，由于是在环形槽的基础上提供更多的容置空间，故金属电极片粘接在环形槽中时，过量的胶黏剂可以被挤压到该台阶体上，使台阶体提供一定的溢胶容置空间，由此来防止因胶水厚度涂抹不均匀导致电极片贴合后不平整的问题，减少装配误差。
此外，设置该台阶体还能对金属电极片的安装起到导向的作用。本申请实施例的环形插接部，其内侧面的根部采用圆角的弧形设置，这就要求安装座中设置凸台时，需要将凸台的四个角部也设置成与环形插接部相匹配的圆角，否则金属电极片在环形槽中的装配会比较困难。然而，在环形槽的内侧槽壁形成该台阶体，也就是在凸台的外壁面形成该台阶体，由于台阶体的设置，使得金属电极片与凸台之间具有一定间距，此时凸台的四个角部无论是设置成圆角、还是设置成直角，都不会对金属电极片在环形槽中的装配产生干扰，由此可以降低对凸台的结构设计要求，也可以减少金属电极片的装配误差。
作为又一种可选的实施方式，还可以同时设置上述两种溢胶结构，给过量的胶黏剂提供更多的挤压释放空间。也就是说，在本申请实施例中，既从环形槽的内侧槽壁沿安装座的径向向外凸出形成台阶体，利用多出来的台阶空间来提供溢胶空间；又使凸台朝自身内凹形成溢胶槽，利用溢胶槽的槽体来提供溢胶空间。
为了使按摩头100具有更多功能，按摩头100还包括发热件3，发热件3固设在金属电极片2的背面22，凸台12朝自身内凹(形成避位空间，发热件3容置于避位空间中，安装座1用于形成避位空间的柔性材料采用热的不良导体材料。
在本申请实施例中，通过在金属电极片2上固设发热件3，可以利用发热件3对金属电极片2进行加热，提升按摩效果。此外为了提高加热效率，在凸台12上对应于设有发热件3的位置处形成避位空间，在金属电极片2的表面与凸台12的表面抵接且粘接时，金属电极片2与凸台12相抵接的表面与避位空间共同围合形成了封闭或者非封闭的腔室，发热件3容置在这个腔室中时，其散发的热量能够通过该腔室集中传递。尤其是本申请实施例中安装座用于形成避位空间的柔 性材料采用的是热的不良导体材料，例如安装座为硅胶座，硅胶就是热的不良导体，这使得发热件3的热量与避位空间进行热交换的损失较小，发热件3的热量更多的传递到金属电极片2上，从而提到热传递效率。
其中，发热件3除了可以固设在金属电极片2的背面22，也可以采用其他安装设置方式。例如发热件3也可以不固设在金属电极片2的背面22，而是固设在避位空间的侧壁或底壁中，又如发热件3还可以是仅容置在避位空间中，既不与金属电极片2的背面22固接、也不与避位空间上的结构固接，实际上只要发热件3容置在该避位空间中，其加热工作时就能够向金属电极片2传热，故在此不对发热件3的固定安装进行限制。
请参阅图11，在本申请实施例中，发热件3为固定贴附在金属电极片2上的发热膜32，避让空间是凸台12内凹形成的凹槽，发热膜32设置在凹槽中，且凸台12围绕在发热膜32周围设置。发热膜32优选设置在金属电极片2的中部，以从中部到四周的传热方式对金属电极片2进行加热。由于发热膜32比发热丝31具有更大的加热表面积，故利用发热膜32加热时具有很好的加热效果。在金属电极片2的表面与凸台12的表面抵接且粘接时，发热膜32相当于设置在凸台12内凹形成的凹槽空间中，其散发的热量能够很好地集中传递给金属电极片2。尤其是安装座为硅胶座，凹槽为硅胶槽，该硅胶槽导热性能不良，故使得发热膜32发出的热量损失较小，可以更多更集中地传递至金属电极片2。
请参阅图16，本申请实施例还提供一种颈部按摩仪，该颈部按摩仪包括基于图1至图9所示的按摩头100，或者该颈部按摩仪包括基于图10至图15所示的按摩头100。
具体地，该颈部按摩仪还包括：中间支架200和连接凸台300，其中连接凸台300的一端与中间支架200连接、另一端与按摩头100中的安装座1连接，连接凸台200、中间支架300、安装座1为一体成型结构。
由于连接凸台200、中间支架300、安装座1为一体成型结构，因此在进行结构装配时，只需要将金属电极片2安装到安装座1中即可，无需再依次将安装座1与连接凸台200装配、连接凸台200与中间支架200装配等多次装配，减少装配步骤，简化装配操作。
以上对本发明实施例公开的一种按摩头及颈部按摩仪进行了详细介绍，本文中应用了具体个例对本发明的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本发明的按摩头及颈部按摩仪及其核心思想；同时，对于本领域的一般技术人员，依据本发明的思想，在具体实施方式及应用范围上均会有改变之处，综上，本说明书内容不应理解为对本发明的限制。
