具体实施方式
下面将结合实施例对本发明的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。 基于本发明中的实施例，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，都属于本发明保护的范围。
目前现有的电动剃刀均需要用户单独按下开关才能启动，使用不方便，基于此，本发明实施例提供的一种电动剃刀及电动剃刀***，可以实现自动启动，方便用户使用，提高用户的体验感。
为便于对本实施例进行理解，首先对本发明实施例所公开的一种电动剃刀进行详细介绍。
本发明实施例提供了一种电动剃刀，该电动剃刀可以是剃须刀，也可以是理发器，还可以是其他用于剔除毛发的电动设备。
参见图1所示的一种电动剃刀的电路结构示意图，图2所示的一种电动剃刀的外观示意图，图3所示的一种电动剃刀的内部结构示意图，以及图4所示的一种电动剃刀的刀头的俯视图，该电动剃刀包括互连的机身10和刀头20；机身10包括外壳110、设置在外壳110内的控制芯片120和驱动部件130、以及设置在外壳110上的手柄感应元件140，刀头20包括头部感应元件210；控制芯片120分别与驱动部件130、手柄感应元件140和头部感应元件210连接，驱动部件130还与刀头20连接。
上述手柄感应元件140设置在机身10的手柄位置(手抓握的位置)，用于感应到皮肤接近时产生第一感应信号，并将第一感应信号发送至控制芯片120；头部感应元件210用于感应到皮肤接近时产生第二感应信号，并将第二感应信号发送至控制芯片120；控制芯片120用于在接收到第一感应信号和第二感应信号时发送驱动控制信号至驱动部件130，以使驱动部件130驱动刀头20工作。
另外，控制芯片120还用于在刀头20工作过程中，当未接收到第一感应信号和第二感应信号，或只接收到第一感应信号和第二感应信号之一时，发送关闭控制信号至驱动部件130，以使驱动部件130停止驱动刀头20。这样实现了电动剃刀的自动关机功能，同时还可以节约电能。
具体地，上述外壳110的材质可以但不限于为塑料。控制芯片120 可以为MCU(Microcontroller Unit，微控制单元)。例如控制芯片120采用单片机，控制芯片120的型号可以但不限于为PL51T020。刀头20可以为一个，也可以为多个，例如刀头20还可以为两个或三个等，本实施例对刀头20的数量不作限定。控制芯片120可以通过传输导体(传输线)分别与驱动部件130、手柄感应元件140和头部感应元件210连接。
上述电动剃刀在手柄感应元件140和头部感应元件210都感应到人体(皮肤)接近时会自动启动，无需用户进行单独按一下开关的操作，因此使用方便，提高了用户的体验感。
上述电动剃刀还具有防误触功能：只有手柄感应元件140和头部感应元件210同时感应到人体接近时才会自动启动，也即用户只接近手柄感应元件140和头部感应元件210之一时，该电动剃刀不会运转或开机，因此有效避免了误触，结构设计更合理。
另外，上述电动剃刀的外观整体看上去无任何按键或推动开关，更有利于做防水处理。
可选地，上述手柄感应元件140包括设置在外壳110的内壁上的第一感应导线圈；如图2至图4所示，刀头20包括金属刀网211，头部感应元件210包括金属刀网211和/或环绕金属刀网211设置的第二感应导线圈。
由于手柄感应元件140和头部感应元件210均为电感线圈，人体为导体，基于天线的工作原理，手柄感应元件140和头部感应元件210均可以在人体接近时产生感应电信号，从而能够实现电动剃刀的自动启动，实现原理稳定可靠。
具体地，如图1至图4所示，刀头20包括金属刀网211和内刀片212，驱动部件130与内刀片212连接。金属刀网211用于配合内刀片212切割毛发(头发或胡须等)，以及防止皮肤被割伤。内刀片212用于在驱动部件130的驱动下相对于金属刀网211运动，以切割毛发。
在一种可能的实现方式中，将金属刀网211作为头部感应元件210。
在另一种可能的实现方式中，可以环绕金属刀网211设置第二感 应导线圈，将该第二感应导线圈作为头部感应元件210。
在又一种可能的实现方式中，将金属刀网211和第二感应导线圈均作为头部感应元件210，金属刀网211和第二感应导线圈分别与控制芯片120连接，控制芯片120在接收到金属刀网211和第二感应导线圈中至少一个发送的信号时，确定接收到头部感应元件210产生的第二感应信号。这样头部感应元件210具有较大的面积，能够及时感应到人体的接近，灵敏度较高。
可选地，上述第一感应导线圈的材质包括铜、钢、铁、铝、锌和镍中的一种或多种；上述第二感应导线圈的材质也包括铜、钢、铁、铝、锌和镍中的一种或多种。
可选地，为了提高安全性，如图2至图4所示，上述第二感应导线圈外包覆有保护层213。该保护层213可以但不限于为塑料件。优选地，该保护层213的材质为软胶，此时可以将该保护层213称为肤感支架，肤感支架的触感较好，可以进一步提高用户的体验感。
图5为本发明实施例提供的另一种电动剃刀的电路结构示意图，如图3和图5所示，上述驱动部件130包括互连的马达控制开关131和马达132，马达控制开关131还与控制芯片120连接，马达132还与刀头20的内刀片212连接；马达控制开关131包括以下中的任一种：晶闸管、晶体管、场效应管、可控硅和继电器。马达132能够带动内刀片212相对于金属刀网211转动，从而实现毛发的切割。
可选地，如图3和图5所示，上述外壳110上还设置有充电接口150，外壳110内还设置有分别与控制芯片120连接的电源转换模块160、充电开关170和电能存储模块180，电源转换模块160还分别与充电接口150和充电开关170连接，充电开关170还与电能存储模块180连接。
具体地，上述电源转换模块160可以为AC(Alternating current，交流)转DC(Direct current，直流)模块(AC/DC转换器)。电能存储模块180用于为整个电动剃刀内的电子元件供电，如图5所示，电能存储模块180还与马达控制开关131连接，从而可以为马达132供电。电 能存储模块180可以但不限于为锂电池。充电开关170包括以下中的任一种：晶闸管、晶体管、场效应管、可控硅和继电器。
上述电动剃刀的充电控制过程如下：电源转换模块160在通过充电接口150连接电源时，会向控制芯片120发送充电连接信号；控制芯片120在接收到充电连接信号时，获取电能存储模块180的电量状态，并在电能存储模块180的剩余电量低于某一预设值时，发送充电控制信号给充电开关170；充电开关170接收到充电控制信号后，闭合开关，使电源转换模块160转换后的电能存储至电能存储模块180，实现为电能存储模块180的充电。其中，上述预设值可以根据实际需求设置，例如将该预设值设置为99％。
可选地，如图3和图5所示，上述外壳110上还设置有充电指示灯190，充电指示灯190与控制芯片120连接。充电指示灯190用于指示电能存储模块180的充电状态。
在一种可能的实现方式中，如图3所示，充电指示灯190包括两个不同发光颜色的LED(Light Emitting Diode，发光二极管)灯，用于分别指示充电中和已充满两种充电状态。例如，采用红色LED灯指示充电中，绿色LED灯指示已充满。
可选地，如图2所示，上述电动剃刀还包括用于固定刀头20的刀头支架220，刀头支架220与机身10连接；如图2和图3所示，刀头20的下方还设置有毛发储藏室230。毛发储藏室230用于存储刀头20剪切掉的毛发。
为了便于理解，本发明实施例还提供了如图6所示的一种电动剃刀的电路图，主要标示出了控制芯片120、手柄感应元件140、头部感应元件210、马达控制开关131、马达132、充电开关170、电能存储模块180和充电指示灯190，其中，马达控制开关131和充电开关170均包括场效应管，充电指示灯190包括两个LED灯(LED1和LED2)。
需要说明的是，图6中未标示的部分还包括电能存储模块180的过充过放保护电路、控制芯片120的供电电路、工作电流检测电路、 电压检测电路和充电温度保护电路等。
另外，还可以在控制芯片120内烧录相应的算法程序，以调节该电动剃刀的感应灵敏度。这样，更容易控制电动剃刀到合适的灵敏度，通过改善灵敏度，可以使电动剃刀的自动启动或关闭的效果达到最佳。图6中未标示的部分还包括位于充电指示灯190上方的软件算法更新模块。
本发明实施例还提供了一种电动剃刀***，包括上述的电动剃刀，还包括充电头；充电头与电动剃刀连接，充电头用于为电动剃刀充电。
具体地，充电头的输入端与电源连接，充电头的输出端与电动剃刀的充电接口连接，这样通过充电头将电动剃刀与电源连接，实现了对电动剃刀的充电。
