为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。
技术术语的解释说明：
1.光谱功率：
一种光源所发射的光谱往往不是单一的波长，而是由许多不同波长的混合辐射所组成。光源的光谱辐射按波长顺序和各波长强度分布称为光源的光谱功率分布。
用于表征光谱功率大小的参数分为绝对光谱功率和相对光谱功率。进而绝对光谱功率分布曲线：指以光谱辐射的各种波长光能量绝对值所作的曲线；
相对光谱功率分布曲线：指将光源辐射光谱的各种波长的能量进行相互比 较，作归一化处理后使辐射功率仅在规定的范围内变化的光谱功率分布曲线。辐射功率最大的相对光谱功率为1，其他波长的相对光谱功率均小于1。
市场上红光理疗产品众多，本申请针对面部护理器进行改进，提出一种新的面部护理器。该面部护理器能够发出400～700nm的近自然光，且近自然光中600～700nm波段的光谱功率大于0.7。本申请中的面部护理器可以为面罩、或具有面罩结构的其他面部护理装置。
请参照图1所示，该面部护理器包括面罩主体100和设置在面罩主体100上的光源模组(图中未示出)，光源模组用于在面罩主体100被佩戴时朝向面部发光。具体的，面罩主体100具有在佩戴时朝向面部的内侧和裸露在外的外侧，其中光源模组可以设置在面罩主体100的内侧壁上，也可以设置在面罩主体100内。当光源模组设置在面罩主体100内时，位于光源模组内侧的部件需为透光材质，以使得光源模组发出的光线可以经该部件射出。
光源模组包括多个白光光源。每个白光光源均能够发出400～700nm的近自然光。面罩主体包括多个功能区域。不同功能区域对应面部的不同部位。每个功能区域内均设置有至少一个白光光源。位于同一功能区域内的所有白光光源发出的光形成的混合光中600～700nm波段的光谱功率大于0.7。这里所说的光谱功率可以为相对光谱功率也可以为绝对光谱功率。相较光谱功率为相对光谱功率，当光谱功率为绝对光谱功率时，位于同一功能区域内的所有白光光源发出的光形成的混合光所形成的光谱更接近太阳谱色，因此光谱功率优选绝对光谱功率。
具体的，本实施例中的功能区域可以根据面部不同部位的肌肉厚度、生物组织特性等中任一特性进行划分，如可以分为与眼睛区域相对应的眼部功能区域、与额头区域相对应的额头功能区域、与鼻梁区域相对应的鼻梁功能区域、与脸颊区域相对应的脸颊功能区域；还可以分为与面部T型区域(包括额头、眼部和鼻梁)相对应的第一功能区域，以及除上述区域外的其他区域相对应的第二功能区域。
本实施例中每个白光光源均可以形成400～700nm的宽光谱，且每个功能区域内的所有光源发出的光形成的混合光中600～700nm波段的光谱功率大于0.7，而600～700nm波段对应红色光，可深入生物组织组织以下5～10mm，可促进人体面部生物组织血液循环，细胞再生。如此可使得每个功能区域对应的面部部位均可以获得较强的红光照射，以确保面部的每个部位均可获得良好的光疗效果。
本申请实施例提供的面部护理器可发出波长为400～700nm的近自然光，其光谱如图2所示，其中不同波段的光具有不同的理疗效果：
480nm光谱能够改善黄褐斑；510nm光谱能够与痤疮丙酸杆菌代谢物内普林的光吸收峰值匹配，可致痤疮细菌死亡；515nm光谱能够淡化肤色表皮色素、美白嫩肤；532nm光谱能够抑制雀斑、老年斑；540nm光谱能够改善面部潮红、红色痘印、玫瑰痤疮等肤质；560nm光谱能够增强皮肤弹性、缩小毛孔、祛皱；590nm光谱能够抑制红痘印、嫩肤、祛黄色斑；592nm光谱能够与血管的光吸收峰值匹配，促进胶原蛋白合成，改善血液循环；615nm光谱能够改善色斑色 沉、祛细纹、嫩肤；633nm光谱可有效增强肌肤胶原细胞的活性(让皮肤水嫩，有弹性、抗皱)；640nm光谱能够抑制毛孔粗大、色沉、祛细纹、嫩肤；650nm光谱能够与细胞线粒体的光吸收峰值匹配，增强细胞供能，促进新陈代谢；660nm光谱能够增强骨髓间充质干细胞迁移能力；670nm光谱能够促进皮质层的新陈代谢(细胞深度修复)；683nm光谱能够与毛囊细胞的光吸收峰值匹配，促进毛发再生；690nm光谱能够改善细胞活性，促进新陈代谢增强肌肤弹性。
本申请实施例提供的面部护理器至少具有如下效果：
第一，本面部护理器中的光源模组能够获得平坦的、连续宽光谱，光能量分布均匀，其谱色与太阳谱色极其相近，而生物组织对自然光谱的适应性是无可替代的，越接近自然光谱的光子能量，更能有效的使人体生物组织产生生物效应，因此连续光谱对生物组织的生长或再生作用，优于单波长的光谱，即本申请实施例提供的面部护理器相比于传统的窄光谱面部护理器，理疗效果更佳。
第二，本实施例中每个白光光源均可以形成宽光谱，且每个功能区域内的所有光源发出的光形成的混合光中600～700nm波段的光谱功率大于0.7，如此可使得每个功能区域对应的面部部位均可以获得较强的红光照射，以确保面部的每个部位均可获得良好的光疗效果。
由于面部生物(肌肉)组织厚度不均，比如脸颊部分生物组织较厚，额头、鼻梁等部分生物组织较薄，此时若不同区域对应的白光光源数量一致，则明显设置不合理。为实现光源模组的合理布局，在一个可选的实施例中，任意两个功能区域内白光光源的密度满足以下关系：
与面部生物组织较厚部位对应的功能区域内的白光光源的密度大于与面部生物组织较薄部位对应的功能区域内的白光光源的密度。其中，白光光源的密度为单位面积内白光光源的个数。
由于红光的理疗原理是对生物体产生光化学作用，使之产生重要的生物效应及治疗效果。而细胞中线粒体对红光的吸收最大，在红光照射后，线粒体的过氧化氢酶活性增加，这样可以增加细胞的新陈代谢，使糖元含量增加，蛋白合成增加和三磷酸腺苷分解增加，从而加强细胞的新生，促进伤口和溃疡的愈合，同时也增加白血球的吞噬作用，提高机体的免疫功能。而生物组织越厚的区域一般细胞个数越多，所需的光线越多，采用本实施例的设置方式，可使得生物组织厚度不同的部位可以根据需求获得相应的光线，同时可以减小白光光源设置不合理所导致的成本增加等问题。
示例性的，与脸颊(生物组织厚度为7～23mm)等生物组织较厚区域对应的功能区域内可以每平方厘米内设置4～16颗白光光源，相邻两个白光光源之间的间距为2～5mm；与额头(生物组织厚度为2～6mm)等生物组织较薄区域对应的功能区域内可以每平方厘米内设置2～6颗白光光源，相邻两个白光光源之间的间距为3～5mm。
上述光源模组可以直接连接电源线，使用时，通过电源线直接通电使用，也可以通过控制装置与电源连接，为提高面部护理器的智能化程度，如图3及图4所示，在一个可选的实施例中，面部护理器还包括与光源模组200电连接的脉冲控制装置300。本实施例中的脉冲控制装置300可以安装与面罩主体 100上，也可以位于面罩主体100外，可采用PWM脉冲调制方式控制光源模组200工作。面部护理器采用本实施例提供的结构，可通过脉冲控制装置300实现光源模组200的智能化控制，如定时开启或者关闭，以及调节光源模组200的亮度等，使得面部护理器适应更多人不同的使用需求，以提升客户体验，扩大产品的适用范围。
示例性的，上述脉冲控制装置300可以包括电源组件、驱动控制器和开关，其中电源组件可以为可充电的电源模块、蓄电池和/或与外接电源连接的连接线等，开关可以与驱动控制器和电源组件串联，使用时通过开关控制电源组件与驱动控制器的连通或者中断，驱动控制器可以由一个或者多个可以编程的控制芯片(如CPU)组成。脉冲控制装置300通过导线与光源模组200连接。
脉冲控制装置300通过PWM控制光源模组200的发光亮度的原理为：通过调节占空比实现不同亮度的变化，占空比代表的是平均电压，占空比发生变化后光源模组200和限流电阻两端的平均电压会发生变化，流过光源模组200两端的电流发生变化，因此，将PWM的占空比调节为最小时，控制光源模组200发出的亮度为最大，在预设时间间隔内增大PWM的占空比，光源模组200发出亮度变暗，并设定占空比的变化周期，以此实现多个亮度的循环切换，模拟太阳发光时明暗亮度的动态闪烁效果。
脉冲控制装置300通过PWM调节光源模组200的色温的原理为：通过改变光源模组200中不同光源的驱动电流，改变各光源的光通量，具体通过PWM分段控制不同光源，比如采用PWMA控制其中一个或者一些光源，采用PWMB控制另一些光源，分别设定PWMA和PWMB的占空比，使得所有光源混合产生的近自然光的色温可调。
为进一步提高面部护理器的智能化程度，如图4所示，在一个可选的实施例中，面部护理器还包括设置在面罩主体100上的温度传感器400。温度传感器400与脉冲控制装置300电连接，用于检测面罩主体100与面部接触一面或者面罩主体100所围设空间内预设区域的温度。这里所说的预设区域可以为距离面罩主体100与面部接触一面预设距离，如1mm、2mm处的某一区域，也可以为面部的某一区域，具体可以根据使用需要人为设置。脉冲控制装置300用于接收温度传感器400的检测数据，并根据温度传感器400的检测数据控制光源模组200的通断以及电流大小。
本实施例中的温度传感器400的设置可使得面部护理器具有控制光生物组织的热效应的作用。具体表现为，使用时，可通过编程设置脉冲控制装置300的功能，使得脉冲控制装置300对温度传感器400所采集的数据进行实时接收，当发现温度传感器400检测到面部护理器与面部接触一面或者面罩主体100所围设空间内预设区域内温度达到第一预设温度(可以为39度，或者其他温度)时，自动调低输送至光源模组200的脉冲电流；当发现温度传感器400检测到面部护理器与面部接触一面或者面罩主体100所围设空间内预设区域内温度达到第二预设温度(可以为41度或者其他温度)时，自动关闭电源，停止对光源模组200进行供电。如此，可有效降低生物组织因光的作用引起其内部温升，对生物酶的活性造成不良影响的风险。
为使得生物组织厚度不同的部位可以根据需求获得相应的光线，除将不同功能区域内白光光源的密度设置为不同时，还可以采用其他方式。在另一个可选的实施例中，脉冲控制装置用于输出与功能区域一一对应的控制信号，以通过控制信号控制各功能区域内白光光源按照预设频率闪烁，使得任意两个功能区域内白光光源满足以下关系：
与面部生物组织较厚部位对应的功能区域内的白光光源的点亮时长大于与面部生物组织较薄部位对应的功能区域内的白光光源的点亮时长。
需要说明的是，本实施例提供的方案可以与上一实施例一同应用，也可以单独应用，具体可以根据使用需要灵活选择。
采用本实施例提供的方案，可根据生物组织不同部位的厚度，逐一分区调整控制信号，来实现更优的美容效果。
为实现上述效果，可采用以下三种方式：
第一种，通过控制信号控制各功能区域内白光光源按照预设频率闪烁，使得任意两个功能区域内白光光源满足以下关系：
与面部生物组织较厚部位对应的功能区域内的白光光源对应的脉冲宽度小于与面部生物组织较薄部位对应的功能区域内的白光光源对应的脉冲宽度。
第二种，通过控制信号控制各功能区域内白光光源按照预设频率闪烁，使得任意两个功能区域内白光光源满足以下关系：
与面部生物组织较厚部位对应的功能区域内的白光光源对应的脉冲间隔小于与面部生物组织较薄部位对应的功能区域内的白光光源对应的脉冲间隔。
第三种，通过控制信号控制各功能区域内白光光源按照预设频率闪烁，使得任意两个功能区域内白光光源满足以下关系：
与面部生物组织较厚部位对应的功能区域内的白光光源对应的脉冲宽度小于与面部生物组织较薄部位对应的功能区域内的白光光源对应的脉冲宽度；
与面部生物组织较厚部位对应的功能区域内的白光光源对应的脉冲间隔小于与面部生物组织较薄部位对应的功能区域内的白光光源对应的脉冲间隔。
采用上述任一种方式均可使得任意两个功能区域内白光光源满足以下关系：
与面部生物组织较厚部位对应的功能区域内的白光光源的点亮时长大于与面部生物组织较薄部位对应的功能区域内的白光光源的点亮时长。使用时，可根据使用需要灵活选择具体设置方式。其中采用第三种方式时，与面部生物组织较厚部位对应的功能区域内的白光光源的点亮时长相较与面部生物组织较薄部位对应的功能区域内的白光光源的点亮时长相差最大。
为使得生物组织厚度不同的部位可以根据需求获得相应的光线，除上述各方式外，还可以采用以下方案：脉冲控制装置300通过电阻与任一功能区域内所有白光光源形成的光源组件串联，以使得任意两个功能区域内白光光源满足以下关系：
与面部生物组织较厚部位对应的功能区域内的白光光源的电流大于与面部生物组织较薄部位对应的功能区域内的白光光源的电流。
采用本实施例提供的方案，可使得不同功能区域内的光源的光通量不同， 与面部中不同部位的生物组织特性相适配，进而使得不同部位均可以实现良好的光疗效果。
示例性的，与脸颊(生物组织厚度为7～23mm)等生物组织较厚区域对应的功能区域内的白光光源的电流可以为5～30mA，脉冲宽度为5mS～90mS，脉冲间隔为5mS～60Ms；与额头(生物组织厚度为2～6mm)等生物组织较薄区域对应的功能区域内的白光光源的电流为3～30mA，优选为5mA～15mA，脉冲宽度为10mS～90mS，脉冲间隔为10mS～60Ms。
在一个可选的实施例中，如图5所示，白光光源包括蓝光芯片210和形成于蓝光芯片210的出光侧的波长转换元件220，蓝光芯片210的峰值波长为440～475nm。其中，蓝光芯片210用于发出蓝光，波长转换元件220用于将蓝光芯片210发出的单色光进行波长转换，产生其他色光(可以为白光或者其他颜色的光)，多种色光混合后形成近自然光。具体的，本实施例中每个白光光源均可发出具有全色仿生光谱的光，也可以发出具有部分光谱的光，只要位于同一发光组件中的所有白光光源发出的光混合后可以形成波长为400～700nm的近自然光，且近自然光中600～700nm波段的光谱功率大于0.7即可。又由于每个白光光源都可以发出近自然光，因此在本光源包含了多个白光光源的情况下，同样能够发出近自然光。
又由于本实施例中每个蓝光芯片210均具有波长转换元件220，根据现有工艺，相较多个蓝光芯片210共用一个波长转换元件220，更易使得每个白光光源的光谱保持稳定，不会因驱动电流的改变而变化。
波长转换元件220作为一种光学换能元件，可以有多种形式，可包括荧光粉色轮、非线性光学晶体或者荧光体等。其中波长转换元件220包括荧光体时，结构简单，有助于光源尺寸控制。具体的，荧光体可以为荧光薄膜、荧光陶瓷、荧光玻璃等。为便于加工，优选荧光薄膜、荧光涂层、荧光胶体等，这些荧光结构一般通过把荧光粉混合在硅胶或者环氧树脂等粘合剂中制成。具体的，当蓝光芯片采用正装方式安装于基底时，荧光体可以为点满整个反射杯后形成的块体结构，也可以为封盖于反射杯顶部的荧光层，还可以采用其他形式具体可以根据实际使用需要而定；当蓝光芯片采用倒装方式安装于基底时，荧光体可以采用荧光薄膜、荧光涂层等结构。更为具体的，蓝光芯片采用倒装方式制备时，可将所有蓝光芯片210依次间隔排布，再统一在所有蓝光芯片210上通过喷涂、印刷等方式制备荧光层，之后再通过切割的方式制备出各个发光单元，最后将各个发光单元组装至基底上，与形成于基底上的电连接件电连接。
在一个可选的实施例中，如图6所示，荧光体包括沿光线出射方向依次设置的第一荧光部221和第二荧光部222，第一荧光部221包括第一荧光粉，第二荧光部222包括第二荧光粉。
本实施例中各荧光部的结构可以根据具体情况而定。举例说明，当蓝光芯片采用正装方式安装于基底，且荧光体为点满整个反射杯的块体结构时，第一荧光部221可以为通过点胶方式铺满反射杯中下部的块体结构，第二荧光部222可以为在第一荧光部321的上表面通过点胶方式充满反射杯中上部的块体结构；当荧光体为薄膜或者层体结构时，第一荧光部221和第二荧光部222 可以为层叠设置的荧光薄膜或者荧光涂层等。
需要说明的是，本实施例中各层内可能含有一种荧光粉，也可以含有多个荧光粉，当有多种荧光粉时，不同荧光粉之间也不发生化学反应，各荧光粉的性质不变，仅是经过该层出射的光线种类随荧光粉种类的增加而增加。如若第一荧光部221内含有一种荧光粉则蓝光芯片210发出的光线经过该层时仅该种荧光粉受激发发出相应波长的光线，若第一荧光部221内含有多种荧光粉则蓝光芯片210发出的光线经过该层时各荧光粉分别受激发发出相应波长的光线，此时该层发出多条不同波长的光线，其他荧光部原理相同。当各荧光部内荧光粉种类越多发出光线的种类越多，最终所有光线混合形成近自然光。
通过使第一荧光部221和第二荧光部222分别包括第一荧光粉和第二荧光粉，可以在成型时灵活的进行第一荧光粉和第二荧光粉的比例以及浓度的调整，以使得所产生的白光光谱更接近自然光。同时，相比两种荧光粉配方混合为一层，采用本实施例提供的荧光体，可使得白光光源整体光损比较小，光效更高。
上述各实施例中，第一荧光部221和第二荧光部222均包括胶体以及分散于胶体中的相应荧光粉。在一些实施例中，在第一荧光部221中，可以控制第一荧光部221中第一荧光粉的浓度为40％～80％，进一步为50％～70％，其中，第一荧光粉的浓度为第一荧光粉在第一荧光粉和胶体总质量中的占比。
第二荧光部222中，可以控制第二荧光部222中第二荧光粉的浓度为40％～85％，进一步为50％～75％，其中，第二荧光粉的浓度为第二荧光粉在第二荧光粉和胶体总质量中的占比。
第一荧光粉和第二荧光粉的浓度大小决定所产生的近自然光的色温，浓度越大，在荧光粉配比和荧光部厚度一定的条件下，浓度越高，色温就越低，浓度越低，色温越高。
在一个可选的实施例中，第一荧光粉包括荧光粉A1、荧光粉A2和荧光粉A3，且荧光粉A1的发光波长488～492nm，荧光粉A2的发光波长为523～542nm，荧光粉A3的发光波长为628～681nm，荧光粉A1、荧光粉A2和荧光粉A3的质量比为(20～70)：(30～70)：(3～15)。第一荧光粉采用本实施例的设置方式，可使得蓝光芯片210发出的光经过该荧光体后发出400～700nm的近自然光。
第二荧光粉包括荧光粉B1和荧光粉B2，荧光粉B1的发光波长为718～722nm，荧光粉B2的发光波长为738～742nm，荧光粉B1和荧光粉B2的质量比为(50～90)：(15～50)。第二荧光粉采用本实施例的设置方式，可使得蓝光芯片210发出的光经过第一荧光体和第二荧光体后发出400～700nm的近自然光。
在一些实施例中，荧光粉A1、荧光粉A2、荧光粉A3、荧光粉B1和荧光粉B2可以包括氮化物、Y3AL12：C和氟化物任一化合物。例如，荧光粉A1可以为镓掺杂钇铝石榴石，具体的如钇三铝镓五氧十二[Y3(Al，Ga)5O12]，荧光粉A2可以为BaSi2O2N2(钡锶二氧二氮二，1222)，荧光粉A3、荧光粉B1和荧光粉B2分别可以为(Ca，Sr)AlSiN3(钙锶铝硅氮三，1113)或氟化物，具体的如K2SiF6:Mn4+(氟硅酸钾)。另外荧光粉A1、荧光粉A2、荧光粉A3、 荧光粉B1和荧光粉B2各发光波长的荧光粉可以根据发光波长直接市购获得。
需要说明的是，荧光粉A1、荧光粉A2、荧光粉A3、荧光粉B1和荧光粉B2中的任一荧光粉具体包括几种化合物并不限定，可以是仅包括一种单一化合物纯净物，也可以是包括多种化合物混合物。例如荧光粉A2还可以包括荧光粉A21、荧光粉A22，荧光粉A3还可以包括荧光粉A31、荧光粉A32和荧光粉A33。当然了，荧光粉A1、荧光粉B1和荧光粉B2也可以是包括一种单一化合物纯净物，也还可以是包括多种化合物混合物。

表4
本申请实施例1至实施例7提供的面部护理器产生的近自然光的光谱与自然光高度相似，其中实施例1至实施例5对应的光谱图如图7至图11所示。该近自然光包括在400～700nm波段下的全部可见光，且600～700nm波段的光谱功率大于0.7，不同波段的可见光均的光功率与自然光接近，使得该近自然光高度模拟自然光，显色指数高，对人体危害小，令人体感受舒适。
在一个可选的实施例中，如图6所示，荧光体采用压膜法制备，第一荧光部221和第二荧光部222的厚度均为0.06～0.15mm。在另一个可选的实施例中，荧光体采用喷膜法制备，第一荧光部221和第二荧光部222的厚度均为0.001～0.01mm。无论采用上述哪种制备方式，荧光体的厚度d均小于等于0.3mm。现有的荧光体一般厚度较大，这样不利于光源散热，且使得光源厚度较大，而荧光体采用本实施例所限定的厚度，可使得光源厚度较小，且有利于蓝光芯片的散热。
在一个可选的实施例中，沿光线出射方向设置的各荧光部的折射率依次增大，即第一荧光部和第二荧光部的折射率依次增大，以使得经蓝光芯片发出的光线的发散角逐渐增大，进而使得各发光单元发出光线的发射角足够大，可以满足使用要求。
上述各实施例中的面罩主体100存在多种设置方式，如面罩主体100可以为一体成型结构，也可以为多个层叠设置的柔性层，为保证面罩主体100的美观性和安全性，在一个可选的实施例中，如图1所示，面罩主体100包括由外至内依次层叠设置的面罩本体110、电路层120和防护层130。光源模组设置于电路层120上。防护层130为绝缘透光层，用于覆盖电路层120和光源模组，并允许光源模组发出的光线穿过。
具体的，本实施例中的面罩本体110可以为一体成型结构，也可以为多个部件的组合结构，如多个层叠设置的层状结构组合而成的层叠结构、多个块体拼接而成的组合结构等。电路层120中包含多条导线、导电条等导电体，具体可以根据光源模组与外接控制装置或者面部护理器自带控制装置电连接关系而定。如根据设计需求，若光源模组仅需要两条导电体与外接或者面部护理器自带控制装置实现串联即可，则电路层120中可以仅设置两条导电体；若光源 模组需要10条导电体才能实现与外接或者面部护理器自带控制装置的连接，则电路层120中需要设置至少10条导电体。除此之外，若面部护理器还具有其他功能，其功能件也可以设置在电路层120上，此时电路层120上的导电体数量也会随之增加。本实施例中的防护层130可以为透光薄膜、透光胶层等，只要能实现上述功能即可。
面罩主体100采用本实施例提供的结构，结构简单，且避免了光源模组200和电路层120外露，使得面罩主体100外形美观且安全性高。
如图1所示，在一个具体的实施例中，面罩本体110包括由外至内依次层叠的外膜111和支撑层112。其中，支撑层112为面罩本体110的主体结构，外膜111为支撑层112的保护层。面罩本体110采用本实施例提供的结构，结构简单，不易损坏，使用寿命长。
为提高面部护理器佩戴的舒适性，在一个可选的实施例中，面罩本体110、电路层120和防护层130均为柔性层。这里所说的柔性层为能够在一定作用力下发生弯曲变形的层状结构。具体的，面罩本体110、防护层130均可以由硅胶、橡胶等柔性材质制成。电路层120可以采用柔性电路板和铜箔等制成。面罩主体100采用本实施例提供的结构，在佩戴时可以根据面部形状变形，提高佩戴时的舒适性，同时还可以使得光源模组200发出的光距离面部距离较近，进而提高光疗效果。
以上所述仅为本申请的较佳实施例而已，仅具体描述了本申请的技术原理，这些描述只是为了解释本申请的原理，不能以任何方式解释为对本申请保护范围的限制。基于此处解释，凡在本申请的精神和原则之内所作的任何修改、等同替换和改进，及本领域的技术人员不需要付出创造性的劳动即可联想到本申请的其他具体实施方式，均应包含在本申请的保护范围之内。
