【背景技术】
为了消除体毛,人们使用各种方式进行脱毛,一般比较常见的是光照脱毛,即通过将皮肤照射强脉冲光,皮肤毛囊中的色素吸收光能发热,毛囊坏死并使毛发脱落,毛发便不再生长,从而达到长久脱毛的目的。
一般的,脱毛仪使用强脉冲光源作为脱毛光源,强脉冲光源为密封有惰性气体(比如氙气)的灯管,灯管上缠绕有线圈,工作时,先向电容充电,然后电容放电,在灯管的正负极施加电压,接着在线圈上施加电压使灯管内的惰性气体电离而导电,最终灯管的正负极导通而使灯管发光。在灯管导通发光时,灯管的电极同时会散发大量的热量,使得脱毛仪的出光口处的接触部温度急剧升高,接触部接触皮肤时使皮肤发烫,脱毛体验差。
为了解决上述,现有的脱毛仪一般是在外壳内设置散热组件,通过散热组件带走接触部的热量而使其温度降低。但是,将散热组件内设置壳体内造成外壳内部拥挤,散热空间小,散热效果差,接触部温度降低有限,效果不理想。

【具体实施方式】
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部份实施例,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。

本申请的脱毛仪100包括可拆卸连接的脱毛机构20和冷敷机构10。脱毛机构20用于向通过将皮肤照射强脉冲光,皮肤毛囊中的色素吸收光能发热,毛囊坏死并使毛发脱落,毛发便不再生长,从而达到长久脱毛的目的。冷敷机构10覆盖脱毛机构20的出光孔,脱毛机构20通过冷敷机构10间接与皮肤接触,冷敷机构10具有制冷效果,从而避免脱毛机构20对皮肤造成的灼热感。
为了使本领域技术人员对本申请有更进一步地认识,以下将详细介绍冷敷机构10。
冷敷机构10包括:冷敷壳组件11、冷敷模块12和热管13。
冷敷壳组件11开设有冷敷孔117和散热孔115,脱毛机构20开设有第一出气孔212和第二出气孔214。冷敷壳组件11与脱毛机构20可拆卸连接,冷敷壳组件11与脱毛机构20装配后,冷敷壳组件11与脱毛机构20间隔形成有气流通道116,气流通道116分别与第一出气孔212和散热孔115连通,第二出气孔214与散热孔115连通。脱毛机构20中的热量一部分依次经过第二出气孔214与散热孔115排出,脱毛机构20中的热量另一部分依次经过第一出气孔212、气流通道116、散热孔115排出,并顺带将冷敷壳组件11中的水汽带出。
冷敷模块12装配于冷敷孔117中与冷敷壳组件11连接,脱毛机构20发出的光线从冷敷模块12射出。冷敷模块12用于与皮肤接触,冷敷模块12具有制冷的效果,从而起到降温效果。
热管13容置于冷敷壳组件11中,热管13的一端与冷敷模块12连接,另一端插置于散热孔115处,热管13将冷敷模块12的热量传送至散热孔115处排出。热管13充分利用了热传导原理与相变介质的快速热传递性质,透过热管13将冷敷模块12中的热量迅速传递到热源的远端,其导热能力超过任何已知金属的导热能力。进一步地,冷敷机构10还包括多个鳍片16,多个鳍片16套设在热管13上对应于散热孔115处,以增大热管13与空气的接触面积,提高散热效率。
冷敷壳组件11包括第一冷敷壳112和第二冷敷壳114,冷敷孔117贯 通第一冷敷壳112和第二冷敷壳114。第二冷敷壳114与第一冷敷壳112的内侧连接,第二冷敷壳114相对于第一冷敷壳112抬升了部分从而形成卡槽117,卡槽117用于与脱毛机构20卡接,从而实现可拆卸的目的。当然,脱毛机构20和冷敷机构10也可以通过磁吸作用实现可拆卸的目的。
在本实施例中,冷敷模块12包括蓝宝石121、传导件122和制冷片123,其中,传导件122用于将蓝宝石121安装在第一冷敷壳112和第二冷敷壳114围成的冷敷孔117内,并与用于与制冷片123接触以传导蓝宝石121和其自身的的热量,最终使蓝宝石121和传导件122维持低温。
具体地,传导件122包括套接部1221、设于套接部1221一端的冷敷部1222、由套接部1221围合形成的套接孔1223以及设于冷敷部1222上的固定柱1224,冷敷部1222部分的延伸至套接孔1223以形成抵压部1225。蓝宝石121收容于套接孔1223内,蓝宝石121的一侧与第二冷敷壳114抵接,另一侧与冷敷部1222的抵压部1225抵接。第一冷敷壳112设有通孔1121,传导件122的固定柱1224抵穿过通孔1121并通过螺丝锁固于第二冷敷壳114上,冷敷部1222抵接第一冷敷壳112,抵压部1225将蓝宝石121压在第二冷敷壳114上,使得蓝宝石121被夹持固定在冷敷部1222与第二冷敷壳114之间,从而完成对蓝宝石121的固定。
为了增加蓝宝石121固定的稳定性,蓝宝石121与抵压部1225和第二冷敷壳144相抵接的两端均设有台阶,抵压部1225和第二冷敷壳144分别与蓝宝石121两端的台阶卡接并相互挤压。
制冷片123贴合在套接部1221的远离蓝宝石121的一侧,其通过套接部1221吸收蓝宝石121和冷敷部1222的热量,从而使蓝宝石121和冷敷部1222维持低温,当冷敷部1222和蓝宝石121与人体皮肤接触时对人体皮肤进行冷敷,以降低人体皮肤温度。传导件122的材质可以是铝、铜等高导热效率的金属材质制成。
在其它实施方式中,冷敷模块12包括也可只包括蓝宝石121和制冷片123,蓝宝石121收容于冷敷孔117内并被第一冷敷壳112和第二冷敷壳114夹持固定,而制冷片123则直接贴在蓝宝石121的侧面,使得蓝宝石 121可以更加快速的降温和维持更低的温度,从而具有更佳的冷敷效果。
蓝宝石121不仅可以透光,而且导热性能优良,可以确保制冷片123与蓝宝石121之间有高效的导热效率,从而使蓝宝石121具有稳定的低温。当然,蓝宝石121也可以用普通玻璃等透光物件代替。
进一步地,冷敷机构10还包括固定座18,固定座18设有固定片181,探针18设于固定片181上,固定片181通过螺丝锁固与第二冷敷壳114。两个制冷片123贴在套接部1221的两侧,热管13的一侧固定在固定座18上,热管13的另一侧与制冷片123远离套接部1221的一侧贴合。其中,制冷片123为半导体制冷片,其制冷面与套接接部1221接触以吸收套接部1221和蓝宝石121热量,从而使套接部1221和蓝宝石121的温度降低;而制冷片124的散热面则与热管13接触,通过热管13内介质的相变吸收制冷片124散热面的热量,从而保证制冷片124的正常工作。
为了使本领域技术人员对本申请有更进一步地认识,以下将详细介绍脱毛机构20。
脱毛机构20包括脱毛壳组件21、滤光片22、发光组件23和鼓风机24。
脱毛壳组件21开设有出光孔218以及第一出气孔212和第二出气孔214,出光孔218和冷敷孔117相对,脱毛壳组件21和冷敷壳组件11于出光孔218和冷敷孔117之间形成有气流通道116,脱毛壳组件21形成有与气流通道116间隔的散热通道118。冷敷壳组件11与脱毛壳组件21可拆卸连接。
滤光片22装配于出光孔218中与脱毛壳组件21连接。由于发光组件23为强脉冲光源,其发出的光包括紫外线和可见光,紫外线容易对人体皮肤造成损伤,因此,需要使用滤光片22过滤发光组件23产生的紫外线。另外,发光组件23在脱毛时产品大量的热量,滤光片22因吸收发光组件23产生的热量而急剧升温,通过将滤光片22和冷敷模块12间隔设置形成第一气流通道116,使得滤光片22和冷敷模块12的隔热能力大幅度提升,避免热量从高温的滤光片22传导至冷敷模块12,使冷敷模块12维持低温。 当冷敷模块12接触人体皮肤时,低温的冷敷模块12有效地降低皮肤的温度,同时钝化皮肤敏感度,提高了用户的使用体验。另外,滤光片22与冷敷模块12之间形成有第一气流通道116,第一气流通道116中空气流动的过程中会将水汽带走,避免滤光片22遇水汽炸裂。
发光组件23装配于脱毛壳组件21中,发光组件23发出的光线依次从滤光片22和冷敷模块12射出。
鼓风机24装配于脱毛壳组件21中,鼓风机24用于朝向第一出气孔212和第二出气孔214吹气,鼓风机24用于加快空气的流动,并使空气按照一定的流向运动。如图2箭头所示方向,在鼓风机24的作用下,脱毛壳组件21中的一部分热量依次经过散热通道118、第二出气孔214、散热孔115排出,脱毛壳组件21中的另一部分热量依次经过第一出气孔212、气流通道116、散热孔115排出,并顺带将冷敷壳组件11中的水汽带出,气流通道116和散热通道118相互独立互不影响。
发光组件23包括装配于脱毛壳组件21中的灯管232和反光罩234,反光罩234罩设灯管232,灯管232的长度方向与鼓风机24的出风方向一致,或者可以理解地,第二出气孔214与散热孔115连线方向与灯管232的长度方向一致,灯管232顺着脱毛壳组件21中空气流动的方向摆放,以减少灯管232对空气流动的阻碍作用,提高脱毛壳组件21中空气流动的速率。
冷敷机构10还包括与冷敷壳组件11连接的探针17,脱毛机构20还包括与脱毛壳组件21连接的触点26,冷敷机构10和脱毛机构20组装在一起时,探针17与触点26电性导通,脱毛机构20为冷敷机构10的冷敷模块12供电。当然,在另一实施例中,探针17也可以设置在脱毛机构20上,触点26设置冷敷机构10上。
请参阅图3和图8,图8是本申请提供的散热支架25的结构示意图。
脱毛机构20还包括与发光组件23连接的散热支架25。散热支架25固定发光组件23,并对发光组件23进行散热。
具体地,散热支架25包括固定部251、主体部253和散热部255,固 定部251的相对两侧设置有主体部253,散热部255与主体部253连接,散热部255用于增大与空气的接触面积,散热部255的延伸方向与鼓风机24的出风方向一致,从而降低散热部255对空气流动的阻挡作用。固定部251设置有固定槽252,发光组件23的灯管232与固定槽252卡接,主体部253与脱毛壳组件21连接。主体部253的数量可以是一个、两个、三个等等,可以理解地,灯管232的数量与主体部253的数量一致。
进一步地,发光组件23还包括电路板236,散热支架25还包括插脚257,插脚257与主体部253的端部连接,插脚257插入电路板236中与电路板236电性连接,从而灯管232通过散热支架25实现与电路板236电性连接的目的。
散热支架25的材质可以是铜、钢、铝等。
综上所述,上述冷敷机构10内置冷敷模块12和热管13,热管13只对冷敷模块12降温,冷敷模块12温度降低幅度大,冷敷效果好;冷敷机构10与脱毛机构20可拆卸连接,可根据脱毛部位更换不同出光口的脱毛机构20;冷敷机构10与脱毛机构20之间形成气流通道116,通过鼓风机24带走冷敷模块12和滤光片22之间的水汽,避免高温滤光片22因接触水滴而破裂;由于气流通道116的存在,冷敷模块12和滤光片22之间存在空气,空气由于热阻高而导热性差,使得冷敷模块12和滤光片22的导热性差,避免冷敷模块12快速升温;脱毛机构20内不设置散热结构,节省大量空间,灯管232和散热支架25的散热效果好,利于鼓风机24对灯管232的散热;散热支架25由导热材质制成,使得散热支架25可作为灯管232的散热器件,而且散热支架25还设有散热部255,进一步增加了散热支架25的散热效果;灯管232及散热支架25的竖向设置于壳体内,即灯管232及散热支架25顺着空气流动的方向设置,这样灯管232及散热支架25对气流阻力小,加快了空气的流动,提高散热效果。
以上所述的仅是本发明的实施方式,在此应当指出,对于本领域的普通技术人员来说,在不脱离本发明创造构思的前提下,还可以做出改进,但这些均属于本发明的保护范围。
