本发明涉及一种毛发切割器具，尤其是指一种二次成型的剃毛刀静刀及其刀片组。The invention relates to a hair cutting appliance, in particular to a secondary molded razor static blade and a blade set thereof.
背景技术Background technique
申请号为201510185524.7的专利申请中公开了一种刀片组、毛发切割器具和相关的制造方法。具体的，所述刀片组包括固定刀片和可动刀片，其中可动刀片可以相对于固定刀片被以往复的方式驱动以用于切割毛发。所述固定刀片包括上下两个固定刀片，两个固定刀片之间形成槽，所述可动刀片插入槽内并在一驱动机构的带动下沿着槽往复移动与固定刀片形成剪切。现有技术中的刀片组件，为了能够剪切更短的毛发以实现更好的剪切效果，都需要设置一个与固定刀片配合使用的支撑结构(固定刀片座)来增加固定刀片的强度，从而避免因固定刀在垂直动刀移动的方向发生弯曲变形而导致动刀在使用时出现抖动或者跳刀的现象。而比较常见的，固定刀片的形成都设置呈一个不闭合的片状结构，利用支撑结构来封闭片状结构的开口同时加强固定刀片的强度。这样设置之后，固定刀片与支撑结构之间围绕形成一个安装空间，所述可动刀片往复移动的设置在该安装空间内。由于剃毛刀在剪切时所需的精度非常高，因此剃毛刀的刀片组中各个元件的配合度的要求也非常高，即使所需精度配合上差了零点几丝米都有可能出现毛发无法剪切以及拉毛或者跳刀的现象。而每增加一个元件，其开模成本以及制造工艺的难度都呈几倍的增加。从以上对现有技术的介绍可知，现有的剃毛刀的刀片组都无法同时解决剃毛刀的强度、剪切效果、制造工艺之间的问题。Patent application No. 201510185524.7 discloses a blade set, a hair cutting appliance and related manufacturing methods. Specifically, the blade set includes a fixed blade and a movable blade, wherein the movable blade can be driven in a reciprocating manner relative to the fixed blade for cutting hair. The fixed blade includes two upper and lower fixed blades, a groove is formed between the two fixed blades, and the movable blade is inserted into the groove and is driven by a driving mechanism to reciprocate along the groove to form shearing with the fixed blade. In the blade assembly in the prior art, in order to be able to cut shorter hairs to achieve a better cutting effect, it is necessary to set a support structure (fixed blade seat) used in conjunction with the fixed blade to increase the strength of the fixed blade, thereby Avoid the vibration or jumping of the moving knife during use due to the bending deformation of the fixed knife in the direction perpendicular to the movement of the moving knife. More commonly, the fixed blades are formed as an unclosed sheet structure, and the support structure is used to close the opening of the sheet structure while strengthening the strength of the fixed blade. After such arrangement, an installation space is formed around the fixed blade and the support structure, and the movable blade is reciprocally arranged in the installation space. Since the precision required by the razor is very high when cutting, the requirements for the coordination of each component in the blade set of the razor are also very high. The phenomenon that the hair cannot be cut, pulled or skipped. And every time a component is added, the mold opening cost and the difficulty of the manufacturing process increase several times. From the above introduction to the prior art, it can be seen that none of the existing razor blade sets can simultaneously solve the problems among the strength, shearing effect and manufacturing process of the razor.
因此，如何同时解决剃毛刀的强度、剪切效果、制造工艺之间的问题，是目前本领域技术人员亟待解决的问题。Therefore, how to simultaneously solve the problems among the strength, shearing effect and manufacturing process of the razor is a problem to be solved urgently by those skilled in the art.

In addition, all the contents of the configurations shown in the following embodiments are not limited to be essential to the solution of the invention described in the claims.
如附图1～6所示，本发明公开了一种二次成型的剃毛刀静刀，包括静刀片1、静刀片支撑架2，所述静刀片1包括一个静刀片本体11以及两个位于静刀片本体11两侧的壁部12。所述两个壁部12分别由静刀片本体11的两端朝向静刀片本体11的中间部位延伸。所述两个壁部12不接触，也就是说所述静刀片1具有一与静刀片本体11相对的开口。具体的，各个壁部12与静刀片本体11之间弧形过渡，壁部12呈无棱角状态的圆弧过渡。静刀片本体11与所述的两个壁部12环绕形成安装空间，所述静刀片支撑架2通过二次成型的方式形成在该安装空间内，所述静刀片支撑架2具有两个分别形成在所述壁部12内侧的支撑壁21，所述静刀片1设置静刀剪切部13，静刀剪切部13形成静刀齿131，相邻的两静刀齿131之间形成剪切槽132。所述二次成型的方式包括注塑、浇铸、或者焊接。所述静刀片支撑架2包括一个与静刀片本体11相对设置的支撑架本体25，所述支撑架本体25连接在两个支撑壁21之间。支撑架本体25封闭静刀片1的开口，从而使得静刀片1与静刀片支撑架2围成一个闭合环。As shown in accompanying drawings 1 to 6, the present invention discloses a static razor blade with secondary molding, including a static blade 1 and a static blade support frame 2, and the static blade 1 includes a static blade body 11 and two Walls 12 located on both sides of the stationary blade body 11 . The two wall portions 12 respectively extend from both ends of the stationary blade body 11 toward the middle of the stationary blade body 11 . The two wall portions 12 are not in contact, that is to say, the stationary blade 1 has an opening opposite to the stationary blade body 11 . Specifically, the transition between each wall portion 12 and the stationary blade body 11 is arc-shaped, and the wall portion 12 has a circular arc transition without corners. The static blade body 11 and the two wall parts 12 surround to form an installation space, the static blade support frame 2 is formed in the installation space by secondary molding, and the static blade support frame 2 has two respectively formed On the support wall 21 inside the wall portion 12, the static blade 1 is provided with a static knife shearing portion 13, the static knife shearing portion 13 forms a static knife tooth 131, and a shear is formed between two adjacent stationary knife teeth 131. Slot 132. The secondary molding method includes injection molding, casting, or welding. The stationary blade supporting frame 2 includes a supporting frame body 25 opposite to the stationary blade body 11 , and the supporting frame body 25 is connected between two supporting walls 21 . The supporting frame body 25 closes the opening of the stationary blade 1 , so that the stationary blade 1 and the stationary blade supporting frame 2 form a closed ring.
如图2所示，所述二次成型的剃毛刀静刀具有两个静刀剪切部13，所述的两个静刀剪切部13形成在静刀片本体11与对应的壁部12的连接处，所述支撑壁21设置与剪切槽132对应的进毛孔22。具体的各个进毛孔22的位置与各个剪切槽132的位置对应。这样设置之后能够加强静刀齿131的强度。在具体实施时，所述二次成型的剃毛刀静刀可以进设置一个静刀剪切部13，并且将所述静刀剪切部13形成在静刀片本体11与其中至少一个壁部12的连接处；或者将所述静刀剪切部13形成在静刀片本体11。在实际使用时，所述二次成型的剃毛刀静刀主要是与一动刀配合使用来切割毛发，所述进毛孔22的设置只要满足：通过剪切槽132进入的毛发能与动刀接触即可。因此，所述进毛孔22也可以设置成一个对应静刀剪切部13的大孔，这样设置之后毛发同样能够进入剪切槽132、进毛孔22，在静刀与动刀的配合下完成剪切。除此之外，这种二次成型的剃毛刀静刀，由于静刀片1有了静刀片支撑架2的支撑，加强了整个二次成型的剃毛刀静刀的强度，因此，本发明所述的二次成型的剃毛刀静刀可以将静刀齿131的厚度做的足够薄，在0.02～0.5mm之间，并且，为了能够剪切更短的毛发，可以在静刀齿131的用于剪切的外周部局部做的更薄，在0.02～0.04mm之间，在剪切作业时静刀的结构依然稳定，不会出现抖动以及变形的问题。As shown in FIG. 2 , the overmolded razor static blade has two static blade cutting parts 13, and the two static blade cutting parts 13 are formed on the static blade body 11 and the corresponding wall part 12. The support wall 21 is provided with pores 22 corresponding to the shear grooves 132 . The specific position of each pore inlet 22 corresponds to the position of each shearing groove 132 . After setting in this way, the strength of the static knife teeth 131 can be enhanced. In a specific implementation, a static knife cutting part 13 can be provided in the secondary molding razor static blade, and the static knife cutting part 13 is formed on the static blade body 11 and at least one of the wall parts 12 or form the stationary blade cutting portion 13 on the stationary blade body 11 . In actual use, the post-molded razor static blade is mainly used in conjunction with a moving knife to cut hair, and the setting of the pores 22 only needs to satisfy: the hair entering through the shearing groove 132 can contact the moving knife That's it. Therefore, described pore-in pore 22 can also be set as a large hole corresponding to the static knife cutting part 13, after setting like this, hair can enter the shearing groove 132, pore-in pore 22 equally, finish cutting under the cooperation of static knife and moving knife. cut. In addition, since the static blade 1 has the support of the static blade support frame 2, the strength of the entire secondary molded razor static blade is strengthened. Therefore, the present invention The secondary molding of the razor static blade can make the thickness of the static blade teeth 131 thin enough, between 0.02 and 0.5 mm, and, in order to cut shorter hairs, the static blade teeth 131 can be The outer peripheral part used for shearing is partially made thinner, between 0.02 and 0.04mm. The structure of the static knife is still stable during the shearing operation, and there will be no problems of vibration and deformation.
如图10所示，所述剪切槽132由静刀齿根部朝向静刀齿末端外扩。具体的，所述剪切槽132呈梯形或开口外扩的“U”形等，不以本实施例揭露的为限制。这样设置之后，更方便毛发进入到剪切槽132内完成剪切，而且不易出现卡齿的现象。As shown in FIG. 10 , the shear groove 132 expands from the root of the stationary blade toward the end of the stationary blade. Specifically, the shear groove 132 is in a trapezoidal shape or a "U" shape with an opening expanding outward, which is not limited by what is disclosed in this embodiment. After setting in this way, it is more convenient for the hair to enter the cutting groove 132 to complete the cutting, and the phenomenon of teeth jamming is not easy to occur.
所述静刀片支撑架2还包括两个包裹端部23，所述包裹端部23形成在所述支撑壁21的两端并连接两个支撑壁21，包裹端部23的顶面与底面相对所述静刀片1的顶面与底面平齐或者凸出。具体的，包裹端部23的外周面相对于对应处的静刀片1的外周面凸出的高度在0～2mm之间。包裹端面部23的外周面无棱角的光滑过渡，提高了使用时的贴肤触感。The static blade support frame 2 also includes two wrapping end portions 23, the wrapping end portions 23 are formed at both ends of the support wall 21 and connect the two support walls 21, the top surface of the wrapping end portion 23 is opposite to the bottom surface The top surface of the stationary blade 1 is flush with or protrudes from the bottom surface. Specifically, the outer peripheral surface of the wrapped end portion 23 protrudes from the outer peripheral surface of the corresponding stationary blade 1 to a height between 0 mm and 2 mm. The smooth transition without edges and corners on the outer peripheral surface of the wrapping end portion 23 improves the skin-attached touch during use.
所述静刀片支撑架2设置包裹槽24，静刀片1的外周缘的至少一部分伸入包裹槽24内被其包裹。所述包裹槽24可以形成在包裹端部23或支撑架本体25。本实施例中，在包裹端部23或支撑架本体25均设置包裹槽24，静刀片1的外周缘被包覆在所述在所述包裹槽24内。所述包裹槽24的设置能加强静刀片1与静刀片支撑架2二次成型后整体结构的稳定性。The static blade support frame 2 is provided with a wrapping groove 24, at least a part of the outer periphery of the stationary blade 1 extends into the wrapping groove 24 and is wrapped by it. The wrapping groove 24 may be formed on the wrapping end 23 or the support frame body 25 . In this embodiment, a wrapping groove 24 is provided at the wrapping end 23 or the support frame body 25 , and the outer peripheral edge of the stationary blade 1 is wrapped in the wrapping groove 24 . The setting of the wrapping groove 24 can enhance the stability of the overall structure of the static blade 1 and the static blade support frame 2 after secondary molding.
所述静刀齿131具有多个外侧面以及连接各个外侧面的端面，静刀齿131的各个外侧面之间、各外侧面与端面之间均弧形光滑过渡连接。这样设计之后，在剃毛时能够提升整体的贴肤触感，并能避免由于操作不当而割伤皮肤。也就是说，在具体实施时，只要将静刀齿131与人体皮肤接触的面均光滑过渡做圆角处理即可。The static knife tooth 131 has a plurality of outer surfaces and end surfaces connecting each outer surface, and each outer surface of the static knife tooth 131 , and between each outer surface and the end surfaces are arc-shaped smooth transition connections. After this design, the overall skin-friendly touch can be improved when shaving, and skin cuts due to improper operation can be avoided. That is to say, in actual implementation, it is only necessary to make the surface of the static knife teeth 131 in contact with the human skin be smooth and rounded.
将所述二次成型的剃毛刀静刀形成闭合环，使得静刀的整体强度增加，其相对于现有技术中静刀是开口的结构设计而言，这种通过二次成型方式形成的环形闭合的静刀整体强度更强。由于剃毛刀在使用时，通常需要对尺寸较短的毛发也能剪切修饰从而达到更加完美的剃毛效果，这就需要静刀与皮肤接触的面做的足够薄，本领域技术人员所熟知。但是，现有的开口式的静刀设计，如果将静刀设计过薄，就没办法保证其与动刀配合所需要的强度；为了克服这一缺陷就需要相应的定刀支撑结构来增加静刀的强度，这种元件的增加势必使得剃毛刀组装难度、工艺步骤及成本均随之增加。而本发明设置二次成型的剃毛刀静刀，简化了现有技术中多个部件相互配合的组装工艺，成型过程中的可控度高(现有技术中对静刀片与对应的支撑结构的尺寸配合要求高，可控性低，装配困难)，在静刀同样厚度的情况下，本发明通过二次成型所形成的环形闭合力使其整体的强度相对于开口设计的静刀而言更强。Forming the overmolded static blade of the razor into a closed loop increases the overall strength of the static blade. Compared with the structure design of the static blade in the prior art, the static blade formed by secondary molding The overall strength of the ring-closed static knife is stronger. Since the razor usually needs to be able to cut and modify shorter hairs so as to achieve a more perfect shaving effect when in use, this requires the surface of the static knife to be in contact with the skin to be thin enough. familiar. However, in the existing open-type static knife design, if the static knife is designed too thin, there is no way to ensure the strength required for it to cooperate with the moving knife; in order to overcome this defect, a corresponding fixed knife support structure is needed to increase the static The strength of the knife, the increase of such components will inevitably increase the difficulty of shaving razor assembly, process steps and costs. And the present invention is provided with the razor static blade of secondary forming, has simplified the assembling process that a plurality of parts cooperate with each other in the prior art, and the controllability in the molding process is high (in the prior art, to the static blade and the corresponding supporting structure The dimensional matching requirements are high, the controllability is low, and the assembly is difficult). In the case of the same thickness of the static knife, the ring-shaped closing force formed by the present invention through the secondary molding makes the overall strength relative to the static knife with the opening design. stronger.
