参见图1所示，本发明一种替换头部的识别方法，包括：
S101，接收替换头部发送的第一频率信号，根据第一频率信号识别出当前使用的头部类型；
S102，接收替换头部发送的第二频率信号，根据第二频率信号识别出当前的工作状态；所述工作状态包括工作温度、工作亮度或工作档位。
本实施例中，替换头部的识别方法可以在手持本部上实现，具体的，在手持本部的主控电路板上实现，所述主控电路板上设置有控制器。不同头部发出的第一频率不同，预先将不同的第一频率与不同的头部类型相关联；所述第二频率信号在所述第一频率信号发送后的一段时间后接收到，第一频率值不等于第二频
率值，判断在设定的延时时间到来是否接收到第二频率，若是则判断为接收到第二频率，若不是接收到的还是第一频率，具体的延时时间根据需要在替换头部端实现。
进一步的，根据第一频率信号识别出当前使用的头部类型之后，还包括：
调整到与头部类型对应的工作模式；所述工作模式包括微电流刺激模式、脸部光疗模式或头部按摩模式。
本实施例中，所述接收替换头部发送的第二频率信号，根据第二频率信号识别出当前的工作状态，具体包括：
若所述工作模式为微电流刺激模式，则将所述第二频率转换成工作温度；
可通过检测工作温度，做相应及时处理(断电保护等)，防止美容仪在高温的情况下连续工作，可延长美容仪的使用寿命；减小设置温度检测电路的触点，有利于产品的小型化设计。
若所述工作模式为脸部光疗模式，则将第二频率转换成工作亮度；
可以以频率为第二频率识别目前用户的光疗亮度，通过监测用户使用的不同亮度的时间，分析用户的使用习惯，系统可自动调整用户最常用的亮度作为默认的初始亮度；减小设定亮度检测电路的触点，有利于产品的小型化设计。
若工作模式为头部按摩模式，则将第二频率转换成工作档位。可以以频率为第二频率识别当前用户使用的工作档位，监测用户使用不同按摩档位的时间推算出用户喜欢的按摩档位，将此档位设置为初始档位。
所述根据第二频率信号识别出当前的工作状态，具体包括：通过存储的拟合方程或关系表获取到与第二频率信号对应的工作温度、工作亮度或工作档位。
参见图2至图4所示，一种美容仪，包括可替换头部10和手持本体20，所述可替换头部10包括三个接触点和频率发生器102；所述手持本体20包括一主控电路板；所述可替换头部10通过第一接触点和第二接触点与所述主控电路板电连接以给频率发生器供电；所述频率发生器102通过第三接触点与所述主控电路板电连接以发送频率信号；所述主控电路板用于执行所述的识别方法。
具体的，所述第一接触点与所述主控电路板的正极相连接，所述第二接触点与所述主控电路板的负极相连接；或者；所述第一接触点与所述主控电路板的负极相连接，所述第二接触点与所述主控电路板的正极相连接。所述第三接触点
是检测频率触点。
本实施例中，所述接触点包括接触顶针101，所述手持本体20上设置有与可替换头的接触顶针101相匹配的接触针孔201。
另一实施例中，所述接触点包括接触针孔201；所述手持本体20上设置有与可替换头的接触针孔201相匹配的接触顶针101。
接触顶针101与接触针孔201相连接的方式，可以是将可替换头部10插入手持本体20的插接方式，还可以是将手持本部插入可替换头的插接方式。
其他实施例中，所述可替换头部10和手持本体20可以不通过插接的方式电连接，还可以嵌入等方式电连接，如在手持本体20上设置让位开口，所述的接触点通过让位开口与主控电路板电连接。
接触点的具体的实现方式可根据实际的需要进行设置，本发明不做限制，只要能够实现上述的通电及发送频率信号的功能即可。
本实施例中，所述手持本体20包括一主控电路板(图中未体现)；所述主控电路板与所述可替换头部10相连接以根据所述频率信号识别出当前使用的头部的类型，以及当前使用的头部的工作状态；所述工作状态包括工作温度、工作亮度或工作档位。
参见图2所示，本实施例中，所述频率发生器102包括脉冲宽度调制器U1，所述脉冲宽度调制器U1可以是555定时器。
所述频率发生器102还包括：第一电阻R1、第二电阻R2和第一电容C1；所述第一电阻R1、第二电阻R2和第一电容C1依次串联，且分别与所述频率发生器102相连接，以调节输出第一频率信号。
具体的，所述第一电阻R1一端与所述脉冲宽度调制器的VCC脚和RST脚分别相连接，另一端与所述第二电阻R2的一端和DS脚分别相连接，所述第二电阻R2的另一端与第一电容C1的一端及TRL脚分别相连接，所述第一电容C1的另一端接地。
其可根据公式T＝ln2*(R1+2*R2)*C1，f＝1/T(T为时间，f为频率)，修改R1，R2，C1的值，可输出不同频率的波形。当所述可替换头与所述手持本体20通过第一接触点和第二接触点连接上后，所述频率发生器102就上电了。所述频率发生器102刚上电时，555定时器根据如下公式T＝ln2*(R1+2*R2)*C1，
f＝1/T输出第一频率信号，所述主控电路板根据第一频率信号来识别前使用的头部的类型。不同类型的头部设定的频率发生器的第一频率不同。
进一步的，在识别出头部的类型后，还需要识别出该头部具体要实现的功能。因此，所述频率发生器102还包括：第一开关管Q1、第四电阻R4、第三电容C3和第三电阻R3；所述第三电容C3与第三电阻R3相串联，且所述第三电容C3与第三电阻R3的连接点与所述第一开关管Q1相连接以控制所述第一开关管Q1的通断；所述第一开关管Q1与第四电阻R4串联后与所述第一电阻R1并联，以调节所述脉冲宽度调制器输出的第二频率信号。
在头部只需设置一个频率发生器，控制器接收频率发生器的信号只需设置一个接收信号的触点即可，控制器无需发送任何控制命令调节第二频率的大小，可由频率发生器的硬件实现第二频率的调节，控制器只需判断是否在设定的时间内接收到第二频率。
具体的，所述第四电阻R4包括NTC电阻、光敏电阻或普通电阻。
所述第一开关管Q1包括MOS管或三极管。本实施例中，所述第一开关管Q1包括MOS管。
具体的，MOS管的栅极与所述第三电容C3和第三电阻R3的连接点相连接，所述MOS管的源极与电源端相连接，所述MOS管的漏极通过第四电阻R4与所述第一电阻R1和第二电阻R2的连接点相连接。
当可替换头部10刚上电时，MOS管尚未导通处于断开状态，555定时器根据公式T＝ln2*(R1+2*R2)*C1，f＝1/T输出第一频率信号，用来识别是哪一个模块头。经过t时间后，MOS管导通，第四电阻R4并联至第一电阻R1两端，555定时器根据公式f＝1/T，输出第二频率信号，用来控制实现不同的功能。
具体的，可以根据需要调整R3和C3值，进而调整所需延迟时间t，具体的关系式可以如下。
MOS管导通条件为：
VR3-VCC<＝-0.7
VR3由RC电路中的电容的充放电时间得出，如下：
当VCC＝5V时，由上述两式可以得出t>＝0.15R3C3，MOS管导通。
参见图3所示，所述可替换头部10还包括一物理开关K1和第四接触点；所述物理开关K1与所述第四电阻R4串联；所述频率发生器102通过所述第四接触点与所述手持本体20相连接以发送按键信号。
参见图3所示，所述频率发生器还包括第一物理开关K1；所述物理开关与所述第四电阻R4串联。
进一步的，所述频率发生器还包括至少一个与所述第一物理开关并联的物理开关，各物理开关串联有对应的电阻。对应的，图3中还包括第二物理开关K2及与K2串联的电阻R5，以及第三物理开关K3及与K3串联的电阻R6，电阻R4、R5和R6的阻值不相同。通过这三个物理开关，能够实现档位切换。
参见图4所示，为本实施例的手持本体20的结构示意图，具体包括开关机按键、档位切换按键和模块切换按键等，档位灯和模式灯分别显示产品当前工作的档位及模式。除接触针孔201部分和主控电路板检测部分有变化外，所述手持本体20的其他部分设计为现有技术，本实施例不做具体说明。
进一步的，参见图2所示，所述可替换头部还包括第四接触点；所述可替换头部通过所述第四接触点与所述手持本体相连接以给外设供电；所述外设包括设置在可替换头部内的电机、加热膜或LED。
需要说明的是，所述第四接触点也可以不需要，具体可以将通过第一接触点和第二接触点提供的电源进行转换后提供给外设使用。本实施例中，为了使得可替换头部内的电路结构简单，因此将可替换头部的接触顶针101统一设置为四个，所述手持本体20中的接触针孔201也统一设置为四个。
如下将结合可替换头部10的几个应用进行具体说明。
应用一：
参见图5及图2所示，可替换头部10为加热模块，第四电阻R4采用NTC，当加热模块与手持本体20接触时，加热模块会发送第一频率信号告知手柄是加热功能，经过一段时间后MOS管导通NTC并联至第一电阻R1两端，此时发送第二频率信号，所述手持本体20中就会实时采集该频率，由公式
f＝1/T，得出第四电阻R4的值，再通过查找NTC的电阻值与温度
的对照表得出当前温度，然后所述手持本体20再根据当前的温度调整输出的功率，实现恒温加热功能。可以理解为上述提到方法中提到的拟合方程，通过拟合方程获取到与第二频率信号对应的工作温度、工作亮度或工作档位。
一实施例中，当R1＝10k，R2＝1k，C1＝1uf时，温度与频率对照表参见图6所示。具体的，电阻值与温度的对照表可预先设置好并存储在主控电路板的MCU中。
应用二：
参加图7及图2所示，可替换头部10为LED模块，第四电阻R4采用光敏电阻，当LED模块与手持本体20接触时，LED模块会发送第一频率信号告知手持本体20是LED功能，经过一段时间后MOS管导通光敏电阻并联至第一电阻R1两端，此时发送第二频率信号，所述手持本体20中就会实时采集该频率，由公式f＝1/T，得出第四电阻R4的值，在通过查找光敏电阻的电阻值与亮度的对照表得出当前亮度，然后手柄再根据当前的亮度调整输出的功率，实现亮度自调节功能。具体的，电阻值与亮度的对照表可预先设置好并存储在主控电路板的MCU中。
应用三：
参见图8及图3所示，可替换头部10为按摩模块，采用三个按键K1、K2和K3，及电阻R4、R5和R6。当按摩模块与手持本部接触时，按摩模块会发送第一频率信号告知手柄是按摩功能，经过一段时间后MOS管导通，当按键K4按下时第四电阻R4并联至第一电阻R1两端，此时发送第二频率信号，告知手持本部按键按下，就可通过该按键来调整按摩模块的按摩力度，若按键没有按下，所述可替换头部10发送的一直是第一频率信号，表示按键没有按下。对应的当按键K5或K6按下时，能够调整按摩模块的按摩力度，即实现档位调节。具体的，按键数量可根据档位需求进行设置。需要说明的是，通过按键实现档位切换的还有多种其他实现方式，具体为现有技术，本实施例不做具体说明。
以上所述，仅为本发明较佳的具体实施方式；但本发明的保护范围并不局限于此。任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，根据本发明的技术方案及其改进构思加以等同替换或改变，都应涵盖在本发明的保护范围
