Description

一种RF美颜仪及其电流控制方法 技术领域
本发明涉及美颜仪技术领域，特别涉及一种RF美颜仪及其电流控制方法。

RF设备美颜的原理为：
RF是一种电磁波，用于RF美容的RF频率一般为100KHz-5MHz，在RF电极输入高频RF电流信号，在正负极电极间会产生高频电场线，从而引起人体组织内带电物质(Na+、K+、CL-)的高频振荡，高频振荡产生热量，同时，RF电流也会产生热量，这些热量会引起人体组织升温，引起蛋白质和纤维达到变性凝固，进而启动皮肤再生修复机制，刺激皮肤胶原纤维、胶原蛋白和透明质酸的新生，达到抗衰除皱的目的。

除非另有定义，本文所使用的所有的技术和科学术语与属于本发明的技术领域的技术人员通常理解的含义相同。本文中在本发明的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本发明。本文所使用的术语“及/或”包括一个或多个相关的所列项目的任意的和所有的组合。
现有的多极RF设备在进行叠加时，不同电极对形成的电场相互吸引，导致射频深度不够，美容效果不佳。
针对上述问题，提出一种RF美颜仪及其电极电流控制方法。
1、矩形排布实施方式
第一方面，如图1，图1是本发明中RF美颜仪逻辑连接示意图；一种RF美颜仪，包括电源140、MCU110、驱动电路120、RF电路130、正负电极对；电源140分别与MCU110、RF电路130连接，用于分别向MCU110、RF电路130提供工作电压；驱动电路120与MCU110连接，用于根据MCU110指令驱动RF电路130产生RF高频电流；正负电极对与RF电路130连接，位于RF美颜仪的同一平面/弧面，且任一周期内施加在正负电极对上的RF高频电流方向相同。
人体组织中的血液、淋巴液及其他组织液均含有大量的水分，故为良好的导电体。此外在人体的组织液中含有大量的离子，如Na+、K+、CL-等，因此能传导电流，在RF高频电流作用下，离子沿电力线的方向移动。RF高频电流正半周时，正离子被推向负极，负离子则相反；负半周时，正离子吸向正极，负离子则相反。
由于RF高频电流频率很高，极性变换很快，离子急剧地沿电力线的方向来回移动或振动；而各种离子的大小、质量、电荷和移动速度不同，在振动过程中互相摩擦以及与周围的媒质相摩擦，产生热量。
双极射频的两个电极同时贴在皮肤的表面，能量从正极出发到达负极，形成半环形的回路。
通过设置正负电极对，控制施加在正负电极对RF高频电流的相位差，使得RF高频电流在每一正负电极对的方向相同。RF电流在人体皮肤中是由带电粒 子的移动形成的，根据同性电荷相斥原理，在人体中两股方向相同的RF电流，上层的RF电流会把下层的RF电流往人体皮肤的更深处推，从而大大增加了射频治疗深度。
优选地，正负电极对包括第一电极对、第二电极对；正负电极对为条状结构，美颜仪的治疗面为矩形结构；第一电极对、第二电极对排布在美颜仪的矩形治疗面区域内。
正负电极对的形状也可以为圆点状结构。
如图7，图7是本发明中电极对实施例示意图，本实施例中的正负电极对为独立设计，也即第一电极对正极、第二电极对正极、第二电极对负极、第一电极对负极分别独立设计。
图7(a)正负电极对也可以一体设计，也即第一电极对正极与第二电极对正极一体设计，第二电极对负极与第一电极对负极一体设计。
图7(b)正负电极对也可以混合设计，也即仅仅采用第一电极对正极或第二电极对正极，将第二电极对负极与第一电极对负极一体设计，也可以第一电极对正极与第二电极对正极一体设计，仅仅采用第二电极对负极或第一电极对负极。
在美颜仪的矩形治疗面内，第一电极对、第二电极对中的正负电极依次间隔排成一列，第一电极对的正负电极排布在外侧，第二电极对的正负电极排布在内侧。
在一个优选实施例中，如图2，图2是本发明中RF美颜仪的矩形排布图案第一实施例示意图；第一电极对、第二电极对在矩形治疗面区域的矩形排布图案为：第一电极对正极、第二电极对正极、第二电极对负极、第一电极对负极；第一电极对正极、第二电极对正极、第二电极对负极、第一电极对负极间隔设置。
在本实施例中，可以将电极之间间隔距离设置为：第二电极对正极、第二电极对负极之间的间隔距离大于第一电极对正极与第二电极对正极、第二电极对负极与第一电极对负极的间隔距离。也可以将电极之间的间隔距离设置为等间距距离。
在本实施例中，施加在第一电极对、第二电极对上的RF高频电流相位差为0°。在本实施方式中，施加在第一电极对上的RF高频电流与第二电极对上的 RF高频电流同步，在皮肤组织150的正离子运动方向及负离子运动方向相同，形成的电流方向相同，根据同种电荷排斥的原理，在正负电极对的能量叠加时，射频治疗深度更深。
在另一个实施例中，矩形排布图案也可以为第一电极对负极、第二电极对负极、第二电极对正极、第一电极对正极。第一电极对中正极与第二电极对中的正极排布在一侧，第一电极对中的负极与第二电极对中的负极排布在另一侧。第一电极对中的正极、负极间隔排布在矩形排布图案的外侧，第二电极对中的正极、负极间隔排布在矩形排布图案的内侧。在本实施方式中，施加在第一电极对、第二电极对上的RF高频电流相位差为0°。在本实施方式中，施加在第一电极对上的RF高频电流与第二电极对上的RF高频电流同步，在皮肤组织150的正离子运动方向及负离子运动方向相同，形成的电流方向相同，根据同种电荷排斥的原理，在正负电极对的能量叠加时，射频治疗深度更深。
如图3，图3是本发明中RF美颜仪的矩形排布图案第二实施例示意图；在另一个实施例中，第一电极对正极与第二电极对正极合并形成第一公共正极，所述第二电极对负极、第一电极对负极共用所述第一公共正极。
在另一个实施例中，第一电极对负极与第二电极对负极也可以合并形成第一公共负极，所述第一电极对正极、第二电极对正极共用所述第一公共负极，也在本申请保护范围之内。

2、环型排布实施方式
优选地，如图4，图4是本发明中RF美颜仪的环型排布图案第一实施例示意图；第一电极对、第二电极对在圆形治疗面区域自边沿到圆心的环型排布图案为：第一电极对正极、第二电极对正极、第二电极对负极、第一电极对负极；第一电极对正极、第二电极对正极、第二电极对负极、第一电极对负极间隔设置；施加在正负电极对上的RF高频电流相位差为0°。
在本实施例中，第一电极对中正极与第二电极对中的正极排布在从边沿到圆心方向依次间隔排布，第一电极对中的负极与第二电极对中的负极从边沿到圆心方向依次间隔排布。第一电极对中的正极、负极间隔排布在环型排布图案 的最外侧和最内侧，第二电极对中的正极、负极间隔排布在第一电极对中的正极与负极之间。
施加在第一电极对上的RF高频电流与第二电极对上的RF高频电流同步，在皮肤组织150的正离子运动方向及负离子运动方向相同，形成的电流方向相同，均指向圆心，根据同种电荷排斥的原理，在正负电极对的能量叠加时，射频治疗深度更深。

优选地，当RF高频电流的频率范围在0.2MHz～2MHz时，射频治疗深度更深。
第二方面，如图6，图6是本发明中RF美颜仪电流控制方法流程示意图；一种RF美颜仪电极电流控制方法，使用第一方面的RF美颜仪，包括：步骤100、在RF美颜仪上治疗面区域设置正负电极对图案；步骤200、驱动RF电路130产生RF高频电流；步骤300、将高频电流时间在正负电极对图案上，且任一周期内RF高频电流在正负电极对上的方向相同；
