所述旋转套具有一容置所述第二检测头、第一检测头和镜头组的空腔；所述空腔的内壁设置有从动齿轮；所述从动齿轮与主动齿轮咬合。
相较于现有技术，本发明的技术方案具备以下有益效果：
本发明提供的一种多功能皮肤检测笔，通过操作件可以实现不同倍数透镜的切换，从而实现不同区域皮肤使用不同倍数的透镜。例如50倍的镜头用于脸部皮肤检测，100倍的镜头用于头皮检测，而500倍的镜头用于头发检测。同时，用于检测头发或者头皮需要用的检测头和检测面部皮肤需要用的检测头不一样，所以操作件除了可以切换镜头外，还可以在从面部皮肤检测切换到头发检测或者头皮检测时，带动第一检测头和第二检测头发生相对运动，从而使得第一检测头相对于第二检测头外凸，这样在头发检测或者头皮检测时就是使用第一检测头进行检测，而在面部皮肤检测时是使用第二检测头进行检测。此外，操作件除了可以带动第一检测头和第二检测头发生相对运动外，还可以带动第一检测头和第二检测头发生一起运动，从而调节第一检测头或者第二检测头与位于检测位置之间的透镜之间的距离，从而实现适配不同倍数透镜的焦距。并且上述过程中，镜头和检测头始终都是安装在皮肤检测笔主体上的，无需拆卸更换，更加便利和卫生。

实施例1
参考图1-图14，本实施例提供了一种多功能皮肤检测笔，包括：皮肤检测笔主体1、与皮肤检测笔主体1活动连接的操作件2、与操作件2连动连接的镜头组3、与操作件2连动连接的第一检测头4和第二检测头5；本实施例中所述第一检测头4嵌设在第二检测头5内，并且第二检测头5的顶部具有供第一检测头4出入的开口。
所述镜头组3包括三个放大倍数不同的透镜，分别为50倍、100倍和500倍。所述操作件2用于带动三个透镜中的一个转动至检测位置，剩余的透镜位于非检测位置；作为本实施例的简单替换，透镜的数量也可以是两个、四个或者更多。
所述操作件2还用于带动第一检测头4和第二检测头5沿着皮肤检测笔主体1轴向运动。这样是为了在切换透镜时，也能够改变第一检测头4和第二检测头5与感光芯片6的距离，也就是改变的物距。这样就可以适配不同的倍数的镜头。此外，由于三个透镜对应由不同的检测项目，需要使用不同的检测头。因此，在切换镜头时还需要切换第一检测头4或者第二检测头5中的一个进行检测。所以，所述操作件2在运动过程中，至少有一阶段带动第一检测头4或第二检测头5沿着皮肤检测笔主体1轴向产生相对运动，以改变第一检测头4和第二检测头5的相对位置，来使得第一检测头4或者第二检测头5处 于生效的状态。具体来说，当所述第一检测头4移动至相对于第二检测头5外凸时，第一检测头4位于检测状态；当所述第一检测头4移动至相对于第二检测头5内凹时，所述第二检测头5位于检测状态。并改变第一检测头4或第二检测头5与位于检测位置的透镜之间的距离，以适配不同透镜的焦距。并且上述过程中，镜头和检测头始终都是安装在皮肤检测笔主体上的，无需拆卸更换，更加便利和卫生。
上述的一种多功能皮肤检测笔，通过操作件2可以实现不同倍数透镜的切换，从而实现不同区域皮肤使用不同倍数的透镜。例如50倍的镜头用于脸部皮肤检测，100倍的镜头用于头皮检测，而500倍的镜头用于头发检测。同时，用于检测头发或者头皮需要用的检测头和检测面部皮肤需要用的检测头不一样，所以操作件2除了可以切换镜头外，还可以在从面部皮肤检测切换到头发检测或者头皮检测时，带动第一检测头4和第二检测头5发生相对运动，从而使得第一检测头4相对于第二检测头5外凸，这样在头发检测或者头皮检测时就是使用第一检测头4进行检测，而在面部皮肤检测时是使用第二检测头5进行检测。此外，操作件2除了可以带动第一检测头4和第二检测头5发生相对运动外，还可以带动第一检测头4和第二检测头5发生一起运动，从而调节第一检测头4或者第二检测头5与位于检测位置之间的透镜之间的距离，从而实现适配不同倍数透镜的焦距。
本实施例中，所述操作件2是采用旋转的方式来实现透镜的切换和检测头的移动的。为此，所述操作件2为皮肤检测笔主体1转动连接的旋转套，由于旋转套的运动方向是绕着皮肤检测笔主体1的轴向， 而第一检测头4和第二检测头5的运动方向是沿着皮肤检测笔主体1的轴向，二者的运动方向不一致，为此本实施例中所述旋转套与第一检测头4和第二检测头5换向配合，从而实现将旋转套的转动换向为旋转套与第一检测头4和第二检测头5的平动。
具体来说为了实现上述的换向配合，所述旋转套的外侧面设置有第一导向槽21和第二导向槽22；所述第一导向槽21和第二导向槽22沿着操作件2侧面的周向延伸，并在延伸的过程中沿着操作件2的高度方向向上或者向下延伸；所述第一检测头4具有置于所述第一导向槽21中的第一卡点41，所述第二检测头5具有置于所述第二导向槽22中的第二卡点51。具体来说，与第二检测头5配合的第二导向槽22是一个单调上升的导向槽，也就是说在旋转套正向转动的过程中，第二检测头5是一个单调上升的平移过程。而与第一检测头4配合的第一导向槽21是一个先上升后下降的导向槽，这样在旋转套正向转动的前一部分过程中，第一检测头4是一个上升的平移过程，而后一部分过程中，第一检测头4是一个下降的平移过程。这样就实现了第一检测头4和第二检测头5在后一部分过程中会发生相对运动。那么只要将旋转套正向转动的后一部分过程中切换的是50倍的镜头，就可以实现第一检测头4运动至相对于第二检测头5内凹的状态下，50倍的镜头和第二检测头5配合进行使用，从而满足面部皮肤检测的需求。
为了实现所述旋转套能带动第一检测头4和第二检测头5平移，所述旋转套具有一容置所述第二检测头5、第一检测头4和镜头组3 的空腔；第一导向槽21和第二导向槽22沿着旋转套侧壁的高度方向间隔设置。此外，所述第一导向槽21和第二导向槽22上分别对于三个镜头设置了三个点位211、221(见附图3-10)。为了保证从动齿轮31自转切换不同镜头的过程中，旋转套相对于第一检测头4和第二检测头5移动至对应的点位211、221时，与该点位对应的镜头也正好移动至与检测位置同轴的状态。需要准确设置三个点位211、221之间的圆心角。
为此本实施例中主动齿轮23与从动齿轮31的齿数分别为36、24，模数均为1。从动齿轮31上三个镜头之间的夹角为120°。由于齿轮分度圆直径＝齿轮齿数x齿轮模数；并且主动齿轮23与从动齿轮31的转动弧长S1和S2应该相等。
又因为转动弧长S＝齿轮分度圆直径X转动角度，因此上述的三个点位211、221所对应的圆心角度间隔由两齿轮分度圆比得出，即：
通过上述计算，可以得到本实施例中相邻两个点位211、221之间的圆心角为80°。如果镜头数量发生变化，或者主动齿轮23与从动齿轮31的齿数发生变化，则上述圆心角也会随之发生变化。
此外，旋转套除了要带动第一检测头4和第二检测头5平移，还需要切换不同的镜头，所以本实施例中所述空腔的内壁设置有主动齿轮23，所述镜头组3设置有与所述主动齿轮23咬合的从动齿轮31，所述透镜设置在从动齿轮31上。通过将所述从动齿轮31相对于主动齿轮23偏心位置，并且所述透镜位于检测位置时与所述操作件2同 轴。这样在主动齿轮23转动的过程中，从动齿轮31发生自转，使得不同倍数的镜头依次经过所述检测位置。
为了固定所述从动齿轮31，所述第一检测头4的侧壁沿着厚度方向设置有卡槽42，所述从动齿轮31与一卡盘32同轴连接，所述卡盘32安装在所述卡槽42中。这样就实现了卡盘32和第一检测头4之间的连接，也就实现了从动齿轮31的安装。并且第一检测头4在移动过程中还可以带动从动齿轮31一起移动。
为了防止从动齿轮31在转动过程中带动第一检测头4和第二检测头5一起转动，从而确保第一检测头4和第二检测头5仅做上下升降运动，本实施例中，第二检测头5的内壁设置防转凸点52，并卡入第一检测头4的对应孔位46；第一检测头4内壁长有防转销孔位44，防转销43连接第一检测头4与皮肤检测笔主体1；旋转套转动时，由于防转销43使得第一检测头4不做旋转运动同时第二检测头5由于防转凸点52卡入第一检测头4中也不做旋转运动。
下文列举三个镜头的具体参数来进行详细的说明：
100倍镜头：第一检测头检测部位至镜头的距离为13.24mm，至感光芯片6距离为36.5mm；
500倍镜头：第一检测头检测部位至镜头的距离为4.68mm，至感光芯片6距离为38.5mm；
50倍镜头：第二检测头的检测部位至镜头的距离为16.5mm，至感光芯片6距离为38.5mm；
旋转套位于初始位置时，100倍镜头位于检测位置，此时第一检 测头4比第二检测头5高出2mm，第一检测头4端口至感光芯片6的距离为36.5mm，满足100倍镜头的要求。第二检测头5端口至芯片距离为34.5mm；旋转至500倍镜头位于检测位置时，第一检测头4和第二检测头5都上升了2mm，此时第一检测头4的端口至感光芯片6距38.5mm，满足500倍镜头的要求。第二检测头5的端口至感光芯片6距离为36.5mm；继续旋至50倍镜头位于检测位置时，第一检测头4下降2mm，第二检测头5继续上升2mm，此时第二检测头5比第一检测头4高出2mm，实现检测头切换。由于从动齿轮31和第一检测头4一起下降2mm，所以此时第二检测头5的端口至感光芯片6的距离增加了2mm，达到了38.5mm。
实施例2
参考图15-图16，本实施例与实施例1的区别在于，本实施例中的操作件2包括旋钮26和旋转套27，其与第一圆锥齿轮24固定连接，以带动第一圆锥齿轮24同轴转动，所述第一圆锥齿轮24与第二圆锥齿轮25咬合，第二圆锥齿轮25通过齿轮轴与主动齿轮33固定连接。所述透镜设置在主动齿轮33上。这样第一圆锥齿轮24转动时就带动第二圆锥齿轮25转动，进而带动主动齿轮33转动，实现切换不同的镜头。由于主动齿轮33与设置在旋转套27的空腔内壁的从动齿轮28咬合。所以主动齿轮33自转时就会带动旋转套27转动，从而是实现镜头切换时，旋转套带动第一检测头4和第二检测头5平移。
实施例3
参考图17-图18，本实施例中所述操作件包括用于驱动步进电机29的启动件和旋转套27，步进电机29的输出转轴与主动齿轮33固定连接。所述透镜设置在主动齿轮33上。这样步进电机29带动主动齿轮33转动时，实现切换不同的镜头。由于主动齿轮33与设置在旋转套27的空腔内壁的从动齿轮28咬合。所以主动齿轮33自转时就会带动旋转套27转动，从而是实现镜头切换时，旋转套带动第一检测头4和第二检测头5平移。本实施例在所述启动件可以是按钮。
以上所述，仅为本发明较佳的具体实施方式，但本发明的设计构思并不局限于此，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，利用此构思对本发明进行非实质性的改动，均属于侵犯本发明保护范围的行为。
工业实用性
本发明一种多功能皮肤检测笔，通过操作件可以实现不同倍数透镜的切换，从而实现不同区域皮肤使用不同倍数的透镜；同时，可以带动第一检测头和第二检测头发生相对运动，或者带动第一检测头和第二检测头发生一起运动，从而调节第一检测头或者第二检测头与位于检测位置之间的透镜之间的距离，进而实现适配不同倍数透镜的焦距。并且上述过程中，镜头和检测头始终都是安装在皮肤检测笔主体上的，无需拆卸更换，更加便利和卫生。
