Description

Technical Field

[0001] The present application relates to the field of razor components, and in particular to a handheld component and a razor. Background Art

[0002] Currently, most razor handles on the market feature streamlined, overall designs, such as a cylindrical shape. To ensure that a handheld razor does not slip out of the hand during shaving, multiple anti-slip stripes or raised anti-slip features are typically provided on the handle surface to increase its stability. Furthermore, to accommodate different gripping or holding methods, the anti-slip features need to be located over a large area of the handle surface, further enhancing its stability. However, this approach utilizes the friction created by the subtle height variations of the anti-slip stripes or raised anti-slip features on the smooth surface of the handle to achieve handle stability. Shaving creams typically contain surfactants and foaming agents, which can fill the anti-slip features or cover their surface to some extent, reducing friction and hand-held stability. This requires the user to grip or hold the handle more firmly to prevent it from slipping out of the hand, increasing the difficulty and consuming more physical effort. Moreover, after long-term use, dirt will remain in the gaps between large areas of anti-slip stripes or multiple anti-slip protrusions, breeding bacteria and causing adverse effects on the user's health. Therefore, how to provide a highly stable handheld component to achieve long-lasting and labor-saving high stability of the handheld component is a technical problem that urgently needs to be solved. Summary of the Invention

[0003] The present application provides a handheld component and a razor to solve the technical problem of poor stability of the anti-slip component of the handle of the razor in the prior art.

[0004] In a first aspect, the present application provides a handheld component, comprising:

[0005] The handle body is symmetrically formed with a continuously expanding smooth curved block along the axial direction, so that the handle body is narrow at the top and wide at the bottom. The end of the smooth curved block is set as a curved surface, so that the smooth curved block is symmetrically set to form a first gripping surface. The side of the handle body opposite to the smooth curved block is set as a flat surface to form a second gripping surface. A first groove is provided in the first gripping surface, and the top of the smooth curved block between the two symmetrical first gripping surfaces is divided into a convex curved surface, a flat surface and a bearing plane. The bearing plane is located at the contact point between the convex curved surface and the flat surface. The convex curved surface and the curved surface have a smooth transition. The flat surface is located above the convex curved surface.

[0006] An arcuate groove, a first upper groove and a first lower groove are provided in the first groove. A dividing line is provided between the arcuate groove and the first lower groove. The top of the arcuate groove is connected to the first upper groove. The first lower groove is designed to be deep at the top and shallow at the bottom.

[0007] Optionally, the depth of the arc-shaped groove on a side close to the first upper groove is smaller than the depth of the arc-shaped groove on a side close to the first lower groove.

[0008] Optionally, the first upper groove is narrow at the top and wide at the bottom, and the first lower groove is wide at the top and narrow at the bottom, so that the upper width of the convex surface is less than the lower width of the convex surface and a convex plane is formed in the first gripping surface.

[0009] Optionally, a second groove and a third groove are provided in the second gripping surface, and the second groove is provided above the third groove.

[0010] Optionally, the area of the second groove is greater than or equal to the area of the third groove.

[0011] Optionally, symmetrical arc-shaped protrusions are provided on the left and right sides of the end of the third groove.

[0012] Optionally, symmetrical receiving grooves are provided on the left and right sides of the second groove.

[0013] Optionally, the bearing plane and the flat surface are arranged at an obtuse angle.

[0014] Optionally, the height of the convex curved surface close to the bearing plane is lower than the height of the convex curved surface close to the curved surface, so that the convex curved surface forms a smooth strip-shaped end surface protruding from top to bottom.

[0015] In a second aspect, the present application provides a shaver, comprising the handheld component described in the first aspect.

[0016] The above technical solution provided by the embodiment of the present application has the following advantages compared with the prior art:

[0017] A handheld component provided in an embodiment of the present application, compared to the usage of a traditional razor, is symmetrically formed with a continuous smooth curved block outward on the basis of the cylindrical handle of the traditional handle body, so that the handle body is narrow at the top and wide at the bottom, so that two symmetrical first gripping surfaces are formed on the side of the handle body, and a second gripping surface is set on the side of the handle body opposite to the smooth curved block, and then a curved surface is set at the end of the smooth curved block (handle body), so that the first gripping surface and the second gripping surface are distributed on the three sides of a triangle, and a first groove is set in the first gripping surface, and the first groove is divided into an arc groove, a first upper groove and a first lower groove In the vertical clamping mode, the thumb and middle finger are both placed in the first lower groove, and the thumb and middle finger abut against the arc-shaped groove. Combined with the design of the first lower groove being deep at the top and shallow at the bottom, the thumb and middle finger can be prevented from sliding up and down; or the thumb is placed in the first lower groove, and the middle finger is bent to the second gripping surface, so that the first knuckle fits into the third groove, and the index finger is straightened so that the first knuckle can be placed in the first upper groove, and the second fingertip of the index finger can abut against the convex curved surface, that is, three fingers can be used to stably grasp the handheld component, thereby realizing another vertical three-finger clamping mode and achieving stable vertical clamping. In one way of horizontal clamping (the other fingers are on the side of the smooth curved block, and the thumb is on the side of the second gripping surface), the first joint of the index finger can be placed on the load-bearing plane or the flat surface, and the first joint of the index finger can be bent against the load-bearing plane, so that the first joint and the second joint of the index finger are respectively extended into the first grooves on both sides, and the first joint of the middle finger is bent against the convex curved surface, so that the first joint of the middle finger is extended into the first lower groove on one side, and the first joint of the ring finger is against the curved surface at the end of the handle, thereby improving the stability of this gripping method; in another way of horizontal clamping (the other fingers are on the side of the second gripping surface, and the thumb is on the side of the smooth curved block), the index finger, middle finger, ring finger or little finger are placed on the second gripping surface, and the thumb is placed on the load-bearing plane or the convex curved surface. , which can evenly distribute the clamping force between the index finger, middle finger, ring finger or little finger and the thumb, thereby making the horizontal clamping stable; compared with the traditional razor handle, this solution optimizes the anti-slip property of the overall shape of the handle by designing a smooth curved block and a first groove, and utilizing the design of the smooth curved block being narrow at the top and wide at the bottom, in combination with the first groove, the bearing plane and the convex curved surface, while reducing the need to set anti-slip stripes or anti-slip protrusions on the smooth plane, which can effectively prevent water flow and shaving cream impurities from remaining on the handheld component, and increases the friction in a way that is more in line with the natural clamping and holding posture of the fingers, while also saving the physical effort of the fingers simply relying on clamping or holding to ensure friction, thereby improving the stability of the handheld component in the razor from a more ergonomic perspective.

DETAILED DESCRIPTION

[0025] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0026] Unless otherwise specified, all raw materials, reagents, instruments and equipment used in this application can be purchased from the market or prepared by existing methods.

[0027] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, an embodiment of the present application provides a handheld component, the handheld component comprising:

[0028] The handle body 1 is symmetrically formed with a continuously expanding smooth curved block 2 along the axial direction, so that the handle body 1 is narrow at the top and wide at the bottom. The end of the smooth curved block 2 is set as a curved surface 3, so that the two sides of the smooth curved block are symmetrically set to form a first gripping surface 5. The side of the handle body 1 opposite to the smooth curved block 2 is set as a plane to form a second gripping surface 6. A first groove 7 is provided in the first gripping surface 5, which divides the top of the smooth curved block 2 between the two symmetrical first gripping surfaces 5 into a convex curved surface 41, a flat surface 42 and a bearing plane 43. The bearing plane 43 is located at the contact point between the convex curved surface 41 and the flat surface 42. The convex curved surface 41 and the curved surface 3 have a smooth transition. The flat surface 42 is located above the convex curved surface 41.

[0029] An arc-shaped groove 73, a first upper groove 71 and a first lower groove 72 are provided in the first groove 7. A dividing line 13 is provided between the arc-shaped groove 73 and the first lower groove 72. The top of the arc-shaped groove 73 is connected to the first upper groove 71. The first lower groove 72 is designed to be deep at the top and shallow at the bottom.

[0030] In the embodiment of the present application, by providing the first upper groove 71 and the first lower groove 72, the contact area and the optimized contact angle between the thumb or middle finger and the handle body 1 can be increased during vertical three-finger clamping. Then, an arc-shaped groove 73 is provided in the first groove 7 to further increase the contact area and the optimized contact angle between the thumb or middle finger and the handle body 1, thereby improving the stability and comfort of use during vertical clamping, and at the same time providing accommodation space for the index finger and thumb during horizontal clamping.

[0031] The deep top and shallow bottom opening design of the first lower groove 72 allows the first knuckles of the thumb and middle finger to be respectively located in the first lower grooves 72 on both sides to clamp the handle body 1, preventing it from sliding up and down toward the blade head, thereby maintaining the stability of the vertical clamping.

[0032] At the same time, the design of the handle body 1 being narrow at the top and wide at the bottom makes the tail of the handle 1 heavier and larger than that of a traditional cylindrical handle. Therefore, compared with a traditional razor, the tail weight of the handle body 1 can be increased. When in use, the vicinity of the load-bearing plane 43 is used as a lever fulcrum. By applying downward force on the lower half of the second gripping surface 6, the razor head surface in the upper half of the second gripping surface 6 can be more easily tilted forward to be close to the face to be shaved, so that it can be used with clamping methods in various directions, thereby improving the usability of the handle body 1; at the same time, the design of the handle body 1 being narrow at the top and wide at the bottom reduces the risk of slipping compared with traditional cylindrical handles when the razor is used to apply downward force to shave in various clamping postures.

[0033] Because the blade surface is on this side of the second gripping surface 6, and due to the design of the handle body 1 being narrow at the top and wide at the bottom, the second gripping surface 6 can provide sufficient plane width when held in the hand. Compared with the traditional cylindrical handle body, the direction of the blade is continuously sensed simply by the touch of the handle with the fingers without the need for vision (suitable for situations where it is inconvenient to keep your eyes open, such as when cleansing your face with facial cleanser or shaving in the shower), so that the blade is always at the correct shaving angle and the risk of lateral rotation and sliding to the left and right is effectively reduced, thereby avoiding the risk of scratching the skin due to blade deflection during shaving.

[0034] In some optional embodiments, the handheld component further comprises:

[0035] The friction part includes a first friction structure 8, a second friction structure 9 and a third friction structure 10. The first friction structure 8 is arranged in the first lower groove 72, the second friction structure 9 is arranged on the bearing plane 43, and the third friction structure 10 is arranged on the flat surface 42.

[0036] In an embodiment of the present application, in another mode of lateral clamping (the other fingers are on the side of the second gripping surface, and the thumb is on the side of the smooth curved block), the designed load-bearing plane 43 and convex curved surface 41 can increase the contact area and optimize the contact angle between the thumb and the handle body 1. In conjunction with the second friction structure 9 and the third friction structure 10, the friction force between the thumb and the handle body 1 can be increased, thereby ensuring smoothness and comfort during lateral clamping. A first friction structure 8 is then provided in the first lower groove 72 to increase the first gripping surface 5 and the friction coefficient, which can effectively prevent the handle body 1 from falling during the three-finger clamping process, thereby improving the stability of the handle body 1 during use.

[0037] In some optional embodiments, the first friction structure 8 , the second friction structure 9 and the third friction structure 10 respectively include anti-slip grooves and / or anti-slip protrusions.

[0038] In the embodiment of the present application, anti-slip grooves or anti-slip protrusions are set in different friction structures. Different anti-slip grooves or anti-slip protrusions can be set according to the sensitivity of different fingers, so as to increase the roughness of the first gripping surface 5, the bearing plane 43 and the flat surface 42, thereby improving the friction coefficient of the handheld component, improving the user experience and improving the stability of the handheld component during use.

[0039] In some optional embodiments, the depth of the arc-shaped groove 73 on a side close to the first upper groove 71 is less than the depth of the arc-shaped groove 73 on a side close to the first lower groove 72 .

[0040] In the embodiment of the present application, by designing the opening of the first lower groove 72 to be deep at the top and shallow at the bottom, and limiting the depth change between the arc groove 73 and the first upper groove 71 and the first lower groove 72, the dividing line 13 between the arc groove 73 and the first lower groove 72 can be made the deepest of the two. Therefore, in the vertical three-finger clamping stage, the arc groove 73 can be used to support the thumb and middle finger to prevent them from sliding toward the blade head, thereby maintaining the stability of the vertical clamping.

[0041] In some optional embodiments, the first upper groove 71 is narrow at the top and wide at the bottom, and the first lower groove 72 is wide at the top and narrow at the bottom, so that the upper end width of the convex surface 41 is less than the lower end width of the convex surface 41 and a raised plane 16 is formed in the first gripping surface 5.

[0042] The first upper groove 71 is designed to be narrow at the top and wide at the bottom. On the one hand, the aesthetics of the handle body 1 can be improved by the setting of narrow at the top and wide at the bottom. On the other hand, the concave surfaces of the first upper groove 71 and the first lower groove 72 can be used to balance the cross-sectional area of each position, thereby balancing the rigidity of each part of the entire handle body 1.

[0043] Control the upper and lower widths of the convex surface 41. When clamping horizontally, when the thumb is placed in the narrower position of the upper half of the convex surface 41, the friction is small, and it can cooperate with the index finger and middle finger on the second gripping surface 6 to flexibly rotate the entire handle and quickly switch between different clamping postures; and when the thumb is placed in the wider position of the lower half of the convex surface 41, there is enough support surface to make the horizontal clamping posture stable at this time.

[0044] Refine the width distribution of the first lower groove 72. The design of the first lower groove 72 being wide at the top and narrow at the bottom can form a raised plane 16 of sufficient width near the lower half of the first gripping surface 5 near the second gripping surface 6, so that in one of the lateral clamping stages (the thumb is on the side of the smooth curved block, and the other fingers are on the side of the second gripping surface), when the first joint of the thumb is placed on the convex curved surface 41 or in the load-bearing plane 43, by bending the middle finger, the first joint and the third joint or the second joint and the base of the finger can clamp the raised planes 16 on the left and right sides. At this time, the second joint or the third joint of the middle finger can abut against the third groove 15, and the index finger can be placed in the second groove 14 of the second gripping surface 6 or in the area above the second groove 14, or the index finger can be bent at the accommodating groove 18 to extend the first joint into the first lower groove 72.

[0045] In some optional embodiments, a second groove 14 and a third groove 15 are provided in the second gripping surface 6 , and the second groove 14 is provided above the third groove 15 .

[0046] In some optional embodiments, the area of the second groove 14 is greater than or equal to the area of the third groove 15 , so that the second groove 14 can accommodate the first joint of the index finger and the third groove 15 can accommodate the second joint of the index finger.

[0047] In the embodiment of the present application, the orientation relationship between the second groove 14 and the third groove 15 is controlled, and the area sizes of the second groove 14 and the third groove 15 are controlled. Since the length of the first joint of the index finger is generally greater than the length of the second joint, by increasing the area of the second groove 14, the index finger can be placed more closely on the second gripping surface 6 during the vertical clamping stage, thereby achieving a stable grip of the handheld component and improving the stability of the handle when it is vertically clamped.

[0048] In some optional embodiments, symmetrical arc-shaped protrusions 17 are provided on the left and right sides of the end of the third groove 15 .

[0049] In some optional embodiments, symmetrical receiving grooves 18 are provided on the left and right sides of the second groove 14 .

[0050] In the embodiment of the present application, an arc-shaped protrusion 17 is provided at the end of the third groove 15, and the second joint of the index finger is fixed by using the arc-shaped protrusion 17 during the vertical clamping stage, so that it can serve as an anti-slip fixing component, which can effectively improve the anti-slip property of the index finger in the left and right directions when the hand-held component is vertically clamped, and the anti-slip property of the finger placed in the third groove 15 in the upward and downward directions when it is horizontally clamped.

[0051] In addition, by providing the accommodating groove 18, the index finger can be placed stably in the second groove 14 laterally during the horizontal clamping stage, or the thumb can be placed in the first lower groove, and the middle finger can be bent to the second gripping surface so that the first knuckle fits in the third groove 15. The index finger is bent so that the joint of the first knuckle and the second knuckle can be placed in the accommodating groove 18, and the index finger is raised at this time; or the index finger is straightened, and the second knuckle of the index finger rests on the convex surface 41. At this time, the first finger of the index finger is inserted into the first upper groove 71, thereby realizing another stable clamping method of vertical clamping.

[0052] In addition, the arc-shaped protrusion 17 is located at the end of the second gripping surface 6, so it also has a certain positioning function, which prevents the risk of the razor falling out of the hand due to the finger passing over the arc-shaped protrusion 17 and grabbing the empty handle when clamping horizontally.

[0053] In some optional embodiments, the bearing plane 43 and the flat surface 42 are arranged at an obtuse angle.

[0054] In the embodiment of the present application, by limiting the angular relationship between the bearing plane 43 and the flat surface 42, the bearing plane 43 can be formed into an upwardly inclined plane, so that the bearing plane 43 provides an anti-slip function toward the tail of the handle when the fingers are placed on the flat surface 42, while increasing the bearing area of the bearing plane 43, facilitating the placement of the fingers in the horizontal clamping stage, thereby increasing the friction between the fingers and the handheld component.

[0055] In some optional embodiments, the height of the convex surface 41 close to the bearing plane 43 is lower than that of the convex surface 41 close to the curved surface 3, so that the convex surface 41 forms a smooth strip-shaped end protruding from top to bottom.

[0056] In the embodiment of the present application, the height change of the convex surface 41 is controlled so that the height of the convex surface 41 expands outward to form a raised smooth strip-shaped end surface. During the lateral clamping stage, the convex surface 41 can disperse part of the clamping force of the thumb or other fingers and provide a friction force opposite to the downward force of the fingers, thereby improving the clamping stability of the handheld component. At the same time, the smooth design of the convex surface 41 can also improve the comfort during the lateral clamping stage.

[0057] In some optional embodiments, a fourth friction structure 11 may be further provided in the second groove 14 , and the distribution of the fourth friction structure 11 may be the same as that of the first friction structure 8 .

[0058] The same fifth friction structure 12 may also be provided in the third groove 15 , and the distribution of the friction structure may be the same as that of the first friction structure 8 .

[0059] In an embodiment of the present application, in a lateral clamping mode (the other fingers are on the side of the smooth curved block 2, and the thumb is on the side of the second gripping surface 6), the first knuckle of the thumb can be placed in the second groove 14, and the first knuckle of the index finger can be placed in the second friction structure 9 of the load-bearing plane 43 or the third friction structure 10 of the flat surface 42, and the first joint of the index finger can be abutted against the load-bearing plane 43 and bent, so that the first knuckle and the second knuckle are respectively extended into the first grooves 7 on both sides, and the first joint of the middle finger abuts against the convex curved surface 41 and bends, so that the first knuckle of the middle finger is extended into the first friction structure 8 in the first lower groove 72 on one side, and the first knuckle of the ring finger abuts against the curved surface 3, thereby improving the stability of this gripping mode.

[0060] In another way of horizontal clamping (the other fingers are on the side of the second gripping surface 6, and the thumb is on the side of the smooth curved block 2), when four-finger clamping is adopted, the index finger can be placed in the area above the second groove 14 in the second gripping surface 6, the middle finger and the ring finger can be placed in the second groove 14, and the little finger can be placed in the third groove 15; or, the index finger can be placed in the area above the second groove 14 in the second gripping surface 6, the middle finger is placed in the second groove 14, and the ring finger is placed in the third groove 15; or, the index finger can be placed in the second groove 14, and the middle finger is placed in the third groove 15. In the above clamping method, the thumb is placed on the third friction structure 10 of the flat surface 42 or the second friction structure 9 of the load-bearing plane 43 or in the convex surface 41 according to the change of the balance point. Therefore, the friction force of different clamping methods can be comprehensively improved by the first friction structure 8, the second friction structure 9, the third friction structure 10, the fourth friction structure 11 and the fifth friction structure 12.

[0061] Based on a general inventive concept, an embodiment of the present application provides a shaver, which includes the handheld component.

[0062] The shaver is implemented based on the above-mentioned handheld component. The specific structure of the handheld component can refer to the above-mentioned embodiment. Since the shaver adopts part or all of the technical solutions of the above-mentioned embodiment, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiment, which will not be described one by one here.

[0063] In the embodiment of the present application, the remaining components of the shaver can adopt any one of the existing technologies, as long as they can achieve the shaving function, such as a traditional blade body or an electric blade body.

[0064] like Figure 2 As shown, in order to further adapt to different handheld component requirements, in addition to the cylindrical handle, when a rotating separate handle is used, the handheld component also includes:

[0065] A rotating device, which is provided in the middle of the second gripping surface 6 and divides the handle body 1 into a first handle block 22 and a second handle block 23 along the transverse direction of the smooth curved block 2;

[0066] The rotating device includes a first contact surface 19, a second contact surface 20 and a rotating shaft 21. The first contact surface 19 is arranged on the end surface of the first handle block 22, and the second contact surface 20 is arranged on the end surface of the second handle block 23. The first contact surface 19 and the second contact surface 20 are engaged with each other to realize the rotational separation between the first handle block 22 and the second handle block 23 through the rotating shaft 21. The engagement point of the first contact surface 19 and the second contact surface 20 is arranged between the second groove 14 and the third groove 15.

[0067] In the embodiment of the present application, the rotating shaft 21 in the rotating device can be utilized. When the three fingers are vertically clamped, the raised rotating shaft 21 can be stuck at the joint between the first and second sections of the index finger, so that the second groove 14 and the third groove 15 can perfectly fit the fingertips of the first and second sections of the index finger, thereby acting as an anti-slip component, which can effectively improve the anti-slip performance. In addition, the rotating shaft 21 also has a certain positioning function. When a horizontal clamping and grasping method is to be adopted, the position of the second groove 14 and the third groove 15 can be found by touching the rotating shaft 21, which is convenient to use.

[0068] In some optional embodiments, the maximum depth of the first contact surface 19 from the end surface of the first handle block 22 is the same as the maximum depth of the second contact surface 20 from the end surface of the second handle block 23, and the maximum distance between the first contact surface 19 and the end surface of the first handle block 22 is greater than or equal to the radius of the rotation axis 21.

[0069] In the embodiment of the present application, by limiting the maximum depth of the first contact surface 19 and the second contact surface 20 from the end faces of their respective handle blocks and the radius of the rotating shaft 21, on the one hand, the support stability of the shaver in the upright stage can be improved, and vertical support force can be provided, thereby reducing the force on the rotating shaft 21 and extending its service life. On the other hand, the first contact surface 19 and the second contact surface 20 can be better fitted together, thereby forming a complete smooth curved block 2, thereby improving the stability of use in various clamping postures.

[0070] The usage process of the razor in this invention is: when shaving is required, the rotating shaft 21 between the first handle block 22 and the second handle block 23 of the handle body 1 in the upright stage is rotated, so that the first contact surface 19 of the first handle block 22 and the second contact surface 20 of the second handle block 23 are engaged, so that the smooth curved block 2 is completely formed. At this time, magnetic materials can be used near their respective end faces in the first contact surface 19 and the second contact surface 20 and are adsorbed together by magnetic force, so as to maintain the stability of the handle body 1 in this shape. At this time, the user performs the shaving operation by vertically clamping with three fingers or horizontally clamping, and cooperates with the first friction structure 8, the second friction structure 9, the third friction structure 10, the fourth friction structure 11 and the fifth friction structure 12 to achieve stable use of the razor.

[0071] After shaving is completed, the first handle block 22 and the second handle block 23 are rotated apart by the rotating shaft 21. At this time, the first contact surface 19 and the second contact surface 20 are separated, so that the first contact surface 19 and the second contact surface 20 together form a stable upright support surface, which can facilitate the stable placement of the shaver and improve the convenience of use.

Furthermore, in the description of this application, the terms "include," "comprising," and the like mean "including but not limited to."
