Description

暴露量可调式剃须刀头 技术领域
本申请涉及剃须领域，尤其涉及一种暴露量可调式剃须刀头。
背景技术
随着经济的不断发展及社会的不断进步，提供了丰富的物质消费品，为提高人们的生活水平及追求个性化的生活创造良好的条件，从而加速了物质消费品的需求量，而手动式剃须刀就是诸多物质消费品中的一种。
众所周知，手动式剃须刀中的剃须刀头一般包括刀头框架、一个或更多个刀片、安装于刀头框架之前侧的防护件及安装于刀头框架之后侧的滑润条；一个或更多个刀片安装在刀头框架位于防护件和滑润条之间的位置处。防护件和润滑条可有助于建立刀片的暴露量，暴露量建立方式是，画一个同时与防护件和润滑条相切的平面，再测得刀片之刀刃与该平面的垂直距离或高度。
其中，在剃须刀头中，其可存在正暴露量、负暴露量和零暴露量(又称中性暴露量)；因为具有一些负暴露量的刀片可更好地保护皮肤同时最佳地切割毛发，并且具有一些正暴露量的刀片可更好地释放被捕集的毛发。存在零暴露量的刀片使皮肤刚好擦过表面。
但是，由于现有的手动式剃须刀中的剃须刀头的刀片的暴露量都是固定不变且不可调节的，使得现有的手动式剃须刀头无法根据实际需要而灵活地调整暴露量以确保更好的剃刮效果。
因此，急需要一种使刀片的暴露量可调以确保剃刮效果的暴露量可调式剃须刀头来克服上述的缺陷。
申请内容
本申请的目的在于提供一种使刀片的暴露量可调以确保剃刮效果的暴露量可调式剃须刀头。

较佳地，所述操作件分别位于所述刀头框架的左侧和右侧处；在同一侧中，所述夹片还横跨并抵压所述操作件，通过拉推所述操作件沿所述刀头框架的左右滑移而连动所述暴露量调整构件做上下方向的滑移调整。
较佳地，所述操作件露于所述刀头框架，所述操作件和暴露量调整构件中的一者具有在所述刀头框架的上下方向倾斜的第一斜面，所述操作件和暴露量调整构件中的另一者具有与所述第一斜面顶推配合的第二斜面或凸起结构；所述操作件在左右滑移的过程中借助所述第二斜面或凸起结构和第一斜面的顶推配合而连动所述暴露量调整构件做上下的滑移调整。

较佳地，所述刀片包含彼此间隔的第一刀片和第二刀片，所述暴露量调整构件位于所述第一刀片和第二刀片之间。
与现有技术相比，由于本申请的暴露量可调式剃须刀头还包括沿刀头框架的前后方向与刀片隔开的暴露量调整构件及与暴露量调整构件连动的操作件，暴露量调整构件位于容纳空间内且沿刀头框架的左右方向延伸，暴露量调整构件的左右两端各被同端的弹腿中余下的一个或更多个所承托，夹片还沿刀头框架的前后方向横跨并抵压暴露量调整构件，以使暴露量调整构件借助弹腿的弹性变形而在刀头框架处上下滑移；操作件活动地安装于刀头框架，操作件可连动暴露量调整构件在刀头框架上做上下方向的滑移调整；因此，当要调整刀片的暴露量时，此时由操作人员对操作件进行操作，由被操作的操作件连动暴露量调整构件在刀头框架上做上下方向的滑移调整，以使得刀片灵活地处于不同的暴露量的位置，从而获得更好的剃须效果；例如，对于自然卷曲的毛发来说，为防止毛发被切断的根部位置过深而在毛发根部的重新生长过程中因卷曲而刺入毛囊所引起的炎症，此时需要使刀片处于负暴露量。

具体实施方式
为了详细说明本申请的技术内容、构造特征，以下结合实施方式并配合附图作进一步说明。
请参阅图1至图5，本申请的暴露量可调式剃须刀头100包括刀头框架10、刀片20、夹片30、沿刀头框架10的前后方向(即箭头A所指方向和相反方向)与刀片20隔开的暴露量调整构件40、与暴露量调整构件40连动的操作件50、安装于刀头框架10之前侧的防护件60及安装于刀头框架10之后侧的润滑条70。刀头框架10开设有用于容纳刀片20的容纳空间11，刀头框架10的左右两侧壁10a(10b)各延伸出位于容纳空间11内且在刀头框架10的前后方向隔开排列的多个弹腿12，例如图2和图5所展示同一端(即左端或右端)的弹腿12的数量为五个，当然，根据实际需要，同一端的弹腿12还可以为三个、四个或六个不 等，故不以此为限。刀片20位于容纳空间11内，且刀片20的左右两端各放置于同端的弹腿12上，以借助弹腿12的上下弹性形变的范围而使得刀片20能做适应的上下滑移调整；较优的是，刀片20包含彼此间隔的第一刀片21和第二刀片22，当然，根据实际需要，刀片20的数量还可为其它，故不以此为限。夹片30分别布置于刀头框架10的左右两侧并装配于刀头框架10，使夹片30与刀头框架10装配在一起；夹片30还沿刀片框架10的前后方向跨设并抵压刀片20，以防止刀片20向上滑出刀片框架10。暴露量调整构件40位于容纳空间11内且沿刀头框架10的左右方向(即箭头B所指方向及相反方向)延伸，使得暴露量调整构件40的左右两端各被同端的弹腿12中余下的一个或更多个所承托，例如被图2和图5所展示的三个弹腿12所承托，当然，根据实际需要可被一个、二个或四个弹腿12所承托，故不以此为限；较优的是，当刀片20包含第一刀片21和第二刀片22时，此时的暴露量调整构件40位于第一刀片21和第二刀片22之间，以确保三者之间彼此留有冲洗间隙，但不以此为限。夹片30还沿刀头框架10的前后方向横跨并抵压暴露量调整构件40，以夹片30的作用下使暴露量调整构件40借助弹腿12的弹性变形而在刀头框架10处做可靠的上下滑移，防止暴露量调整构件40意外滑出刀头框架10。操作件50活动地安装于刀头框架10，操作件50可连动暴露量调整构件40在刀头框架10上做上下方向的滑移调整。防护件60和润滑条70各沿刀头框架10的左右方向延伸并在刀头框架10的前后方向位于容纳空间11的外面，使刀片20和暴露量调整构件40在刀头框架10的前后方向位于防护件60和润滑条70之间。可理解的是，根据实际需要，可以将防护件60和/或润滑条70去除，即刀头框架10的前侧不安装有防护件60和/或刀头框架10的后侧不安装有润滑条70，故不以此为限。更具体地，如下：
如图1至图4所示，操作件50分别位于刀头框架10的左侧和右侧处，以便于操作人员借助刀头框架10左右两侧的操作件50去调整暴露量调整构件40；其中，在同一侧(即刀头框架10的左侧或右侧)中，夹片30还横跨并抵压操作件50，以防止操作件50向上滑出刀头框架10；故通过拉推操作件50沿刀头 框架10的左右滑移，从而连动暴露量调整构件40做上下方向(即箭头C所指方向及相反方向)的滑移调整；例如在图4中，拉动左侧的操作件50往左侧滑移及右侧的操作件50往右侧滑移(方向参见它们旁边箭头所指)的过程中，并在弹腿12的弹性作用下，使得暴露量调整构件40向上滑移而回复至初始位置，初始位置的状态见图10b所示；而滑至图4所示的预设位置的暴露量调整构件40的状态见图10a所示。具体地，在图2、图4、图6、图8及图9中，操作件50露于刀头框架10，暴露量调整构件40具有在刀头框架10的上下方向倾斜的第一斜面41，操作件50具有与第一斜面41顶推配合的第二斜面52；故在操作件50的左右滑移过程中，操作件50借助第二斜面52和第一斜面41的顶推配合而连动暴露量调整构件40做上下的滑移调整，以简化操作件50与暴露量调整构件40之间的连动结构，且使得两者的连动装配关系及连动结构的加工更容易；当然，根据实际需要，操作件50也可具有与第一斜面41顶推配合的凸起结构，例如但不限于此的凸点等，一样能实现操作件50在左右滑移过程中借助凸起结构和第一斜面41的顶推配合而连动暴露量调整构件40做上下的滑移调整的目的。其中，为确保调整效果，操作件50上设有定位结构52a，较优的是，定位结构52a位于第二斜面52上；暴露量调整构件40设有与定位结构52a配合的配定结构42，较优的是，配定结构42位于第一斜面41上，以在操作件50连动暴露量调整构件40滑移至图4所示的预设位置时使定位结构52a与配定结构42定位配合，有效地防止操作件50在失去外力的作用下及弹腿12驱使暴露量调整构件40向上滑移复位的作用下而被动地回到初始位置；举例而言，定位结构52a为定位凸，例如但不限于图4和图9所展示的球形凸点，对应地，配定结构42为定位凹，例如但不限于此的球形凹。另，为进一步地确保调整效果，操作件50远离第二斜面52的位置处也设有定位结构52b，对应地，刀头框架10也设有配定结构12，当暴露量调整构件40滑移至图4所示的预设位置时，操作件50上的定位结构52b也与刀头框架10上的配定结构12定位配合；举例而言，定位结构52b为方形块而配定结构12为方形槽。可理解的是，根据实际需要，第一斜面41可由操作件50所具有，对应地，第二斜面52或凸起结构可 由暴露量调整构件40所具有，故不以此为限；另，虽然图6所展示的第一斜面41由暴露量调整构件40之左端和右端的顶面41所具有，它的位置还可以是其他，故不以此为限；此外，根据实际需要，配定结构42还可由夹片30或刀头框架10所具有，故不此为限。需要说的是，由于定位结构52a(52b)，且操作件50受夹片30抵压，故在定位结构52a(52b)未与对应的配定结构42(12)定位时，此时的定位结构52a(52b)会顶推夹片30向上抬起而确保操作件50于刀头框架10上滑移的顺畅性；同理，在定位结构52a(52b)与对应的配定结构42(12)定位时，此时的夹片30下降。
如图2所示，刀头框架10的左侧壁10a和右侧壁10b各开设有相互连通的导滑槽14和限位槽15。导滑槽14沿刀头框架10的左右方向贯穿布置并与容纳空间11相连通，限位槽15与容纳空间11相隔开且两者之间具有一限位结构16，操作件50同时装配于导滑槽14和限位槽15中，以在操作件50连动暴露量调整构件40滑移至图4所示的预设位置时，由限位结构16对操作件50进行阻挡，防止操作件50向刀头框架10内滑移过渡。具体地，限位槽15位于导滑槽14的正上方，而导滑槽14平分限位槽15；另，配定结构12位于导滑槽14中。
如图6至图8所示，暴露量调整构件40的左端和右端各设有一对彼此间隔且向下凸出的装配腿43，较优的是，暴露量调整构件40之左端的装配腿43还向左凸伸，暴露量调整构件40之右端的装配腿43还向右凸伸，装配腿43装配于刀头框架10内，以确保暴露量调整构件40与刀头框架10之间装配的可靠性。具体地，暴露量调整构件40的顶面44设有多个彼此隔开且沿刀头框架10的前后方向横向于暴露量调整构件40的筋条45，筋条45为中间相对两边凸起的拱形，状态见图7所示，以使得暴露量调整构件40在剃须过程中更好地与皮肤贴合。更具体地，筋条45的宽度为中间大而两边小，以使相邻两筋条45之间所围出的导引通道46的宽度为中间小而两边大，即导引通道46的前后两端宽而中间窄，以便于越过第一刀片21的毛发于导引通道46的前端收集和后端释放，因而便于第二刀片22对穿过导引通道46的毛发继续剃刮。另，暴露量调整构件40位于相邻两筋条45之间的部位上下贯穿地开设有通孔47，通孔47与导引 通道46相连通，以便于排走剃刮碎物，提高冲洗能力。
需要说明的是，暴露量调整构件40不具有切割功能，它的作用是用于对皮肤提供控制点，并分别与防护件60和润滑条70一起建立剃须平面；例如，在图10a中，由于暴露量调整构件40被操作件50连动而滑移至图4所示的预见设位置，此时的暴露量调整构件40与防护件60建立剃须平面P1，与润滑条70建立剃须平面P2，对应地，第一刀片21相对剃须平面P1的暴露量为D1，第二刀片22相对剃须平面P2的暴露量为D2；例如，在图10b中，由于暴露量调整构件40向上回到初始位置，此时的暴露量调整构件40与防护件60建立剃须平面P1`，与润滑条70建立剃须平面P2`，对应地，第一刀片21相对剃须平面P1`的暴露量为D1`，第二刀片22相对剃须平面P2`的暴露量为D2`；从图10a和图10b对比得到，第一刀片21和第二刀片21在暴露量调整构件40向下滑移至预设位置时的暴露量小于暴露量调整构件40向上滑移至初始位置的暴露量。另，暴露量调整构件40可以金属件或非金属件，故不以此为限。
结合附图，对本申请的暴露量可调式剃须刀头100的调整过程进行说明：如图4所示，当要将处于预设位置的暴露量调整构件40调整至如图10b所示的初始位置时，此时，操作人员将图4中的左侧的操作件50向左侧拉出，以及将图4中的右侧的操作件50向右侧拉出，借助第二斜面52和第一斜面41的配合，以及在弹腿12向上复位的作用下，使得操作件50连动暴露量调整构件40向上滑移至如图10b所示的初始位置；当要将图10b所示的处于初始位置的暴露量调整构件40滑移调整至图10a所示的预设位置时，此时操作人员将左侧的操作件50向刀头框架10内推入，以及将右侧的操作件50向刀头框架10内推入，借助第二斜面52和第一斜面41的配合，使得操作件40连动暴露量调整构件40在克服弹腿12的弹力而向下滑移，直到定位结构52a与配定结构42相定位，以及定位结构52b与配定结构12相定位为止，状态见图10a所示。
与现有技术相比，由于本申请的暴露量可调式剃须刀头100还包括沿刀头框架10的前后方向与刀片20隔开的暴露量调整构件40及与暴露量调整构件40连动的操作件50，暴露量调整构件40位于容纳空间11内且沿刀头框架10的左 右方向延伸，暴露量调整构件40的左右两端各被同端的弹腿12中余下的一个或更多个所承托，夹片30还沿刀头框架10的前后方向横跨并抵压暴露量调整构件40，以使暴露量调整构件40借助弹腿12的弹性变形而在刀头框架10处上下滑移；操作件50活动地安装于刀头框架10，操作件50可连动暴露量调整构件40在刀头框架10上做上下方向的滑移调整；因此，当要调整刀片20的暴露量时，此时由操作人员对操作件50进行操作，由被操作的操作件50连动暴露量调整构件40在刀头框架10上做上下方向的滑移调整，以使得刀片20灵活地处于不同的暴露量的位置，从而获得更好的剃须效果；例如，对于自然卷曲的毛发来说，为防止毛发被切断的根部过深而在毛发根部的重新生长过程中因卷曲而刺入毛囊所引起的炎症，此时需要使刀片20处于负暴露量。
值得注意者，夹片30可为金属片或非金属片，虽然图1至图3所展示的刀头框架10左右两侧的夹片30彼此独立，当然，可以根据实际需要而使头框架10左右两侧的夹片30连成一体，故不以此为限。另，附图中的箭头A所指方向为刀头框架10由前往后的方向，箭头B所指的方向为刀头框架10由左至右的方向，箭头C所指的方向为刀头框架10由上至下的方向。
以上所揭露的仅为本申请的较佳实例而已，当然不能以此来限定本申请之权利范围，因此依本申请权利要求所作的等同变化，仍属于本申请所涵盖的范围。
