Description

Technical Field

[0001] This utility model relates to the technical field of razors, specifically to a reciprocating razor head with a reinforcing rib structure. Background Technology

[0002] Razors are divided into reciprocating razors and rotary razors. They are driven by a power source to move the razor head to achieve a shaving effect.

[0003] Existing reciprocating razor heads typically consist of an outer foil and a cutting blade. The cutting blade uses a one-piece, straight-edged design, and the drive source moves the cutting blade relative to the outer foil to cut the beard. However, during the movement of the cutting blade, the straight edge on the blade will tilt due to resistance during high-speed reciprocating motion. This prevents the blade from effectively cutting the beard, resulting in poor cut smoothness and low cutting efficiency. Utility Model Content

[0004] This invention provides a reciprocating shaver head with a reinforcing rib structure to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, this utility model provides a reciprocating shaver head with a reinforcing rib structure, comprising: The outer blade guard has an internal mounting cavity; A cutting blade mesh is disposed within the mounting cavity. The cutting blade mesh has a first cutting unit and a second cutting unit. At least one second cutting unit is disposed between two adjacent first cutting units, and the second cutting unit is inclined relative to the first cutting unit.

[0006] Preferably, two second cutting units are provided between two adjacent first cutting units, one of which is inclined along a first direction and the other is inclined along a second direction, with the first direction and the second direction being symmetrically arranged.

[0007] Preferably, the angle α between the first direction and the second direction is 0° < α < 180°.

[0008] Preferably, two second cutting units are provided between two adjacent first cutting units, and the two second cutting units are arranged in parallel.

[0009] Preferably, the two sets of second cutting units on both sides of any first cutting unit are arranged symmetrically with respect to the first cutting unit.

[0010] Preferably, between two adjacent first cutting units, a cutting space is formed between the two first cutting units, and the two second cutting units are used to divide the cutting space into a first cutting space and a second cutting space.

[0011] Preferably, the second cutting space is formed between the two second cutting units and the two first cutting units.

[0012] Preferably, the cutting blade mesh reciprocates relative to the outer blade mesh along a third direction, the cutting direction of the first cutting unit is perpendicular to the third direction, and the cutting direction of the second cutting unit is inclined relative to the third direction.

[0013] Preferably, the second cutting unit is a straight line, a broken line, or a curve.

[0014] Preferably, the reciprocating razor head with reinforcing ribs further includes: A drive connector is disposed within the mounting cavity, and the cutting blade mesh is disposed on the side of the drive connector near the outer blade mesh.

[0015] The reciprocating shaver head with reinforcing ribs proposed in this utility model has the following beneficial effects: 1. The reciprocating razor head with reinforcing rib structure proposed in this utility model, when in use, the beard enters the mounting cavity through the outer blade mesh hole and forms a cutting pair with the cutting blade mesh. The first cutting unit provides linear cutting in the reference direction, and the second cutting unit located in between and in an inclined direction provides a cutting edge at a different angle from the reference direction.

[0016] When the beard cannot form an effective cut with the first cutting unit, the second cutting unit performs supplementary cutting, thereby forming a composite multi-directional cutting of a straight main blade and an inclined secondary blade within the blade plane.

[0017] A second cutting unit is provided between adjacent first cutting units, which is inclined relative to it. This can expand the effective cutting angle and provide different cutting directions, reduce the impact of instantaneous sway of the straight blade caused by motion resistance on the cutting effect, and make it easier for the cutting blade net and the outer blade net to maintain a basically parallel cooperation state during operation.

[0018] Meanwhile, the distribution of cutting load in different directions helps to suppress the bending or tilting of the first cutting unit due to resistance during the cutting process, thereby improving the efficiency of capturing and shaving beards with different growth directions and close proximity, reducing slippage and missed cuts, comprehensively improving shaving efficiency and post-shave smoothness, and reducing pulling and friction discomfort.

[0019] 2. The reciprocating shaver head with reinforcing rib structure proposed in this utility model has a triangular structure formed between the second cutting unit and the two first cutting units, which increases the stability between the two adjacent first cutting units and avoids the problem of shaking or deformation of the first cutting unit during reciprocating motion.

[0023] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0024] It should be noted that in the description of this utility model, the terms "lateral," "longitudinal," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] This utility model proposes a reciprocating shaver head 100 with a reinforcing rib structure, comprising: The outer blade plate 110 has an internal mounting cavity 110a; A cutting blade mesh 120 is disposed in the mounting cavity 110a. The cutting blade mesh 120 has a first cutting unit 121 and a second cutting unit 122. At least one second cutting unit 122 is disposed between two adjacent first cutting units 121. The second cutting unit 122 is inclined relative to the first cutting unit 121.

[0026] Please refer to Figures 1-6 In this embodiment, when in use, the beard enters the mounting cavity 110a through the opening of the outer blade 110 and forms a cutting pair with the cutting blade 120. The first cutting unit 121 provides linear cutting in the reference direction, and the second cutting unit 122 located therebetween and in an inclined direction provides a cutting edge at a different angle from the reference direction.

[0027] When the beard cannot form an effective cut with the first cutting unit 121, the second cutting unit 122 performs supplementary cutting, thereby forming a composite multi-directional cutting of a straight main blade and an inclined secondary blade in the blade plane.

[0028] A second cutting unit 122 is provided between adjacent first cutting units 121, which is inclined relative to it. This can expand the effective cutting angle and provide different cutting directions, reduce the impact of instantaneous sway of the straight blade caused by motion resistance on the cutting effect, and make it easier for the cutting blade net 120 and the outer blade net 110 to maintain a basically parallel working state during operation.

[0029] Meanwhile, the distribution of cutting load in different directions helps to suppress the bending or tilting of the first cutting unit 121 due to resistance during the cutting process, thereby improving the efficiency of capturing and shaving beards with different growth directions and close proximity, reducing slippage and missed cuts, comprehensively improving shaving efficiency and post-shave smoothness, and reducing pulling and friction discomfort.

[0030] It should be noted that the outer blade mesh 110 has an arc-shaped mesh structure, and the mounting cavity 110a is a hollow cavity.

[0031] Preferably, two second cutting units 122 are provided between two adjacent first cutting units 121, one of which is inclined along a first direction A and the other is inclined along a second direction B, with the first direction A and the second direction B being symmetrically arranged.

[0032] Please refer to Figures 1-6 In this embodiment, two second cutting units 122 are arranged between two adjacent first cutting units 121. One of them is inclined relative to the first cutting unit 121 along the first direction A, and the other is inclined along the second direction B which is a mirror image of it. The two directions are symmetrical with a common reference (such as the extension direction of the first cutting unit 121 or the third direction C of the reciprocating motion) as a reference.

[0033] The two second cutting units 122 are located in the same gap area between the two first cutting units 121 on the cutting blade net 120, and can form a composite arrangement of straight main blade and double inclined secondary blade with the first cutting unit 121.

[0034] Two second cutting units 122 are tilted in the same gap to provide two effective cutting edges in opposite directions. When the direction of beard entry is not good at cutting the shaving angle with one of the second cutting units 122, it can often form a better angle with the other second cutting unit 122 and be captured and shaved.

[0035] Meanwhile, the forces on the outer edge of the cutter mesh 110 by the two first cutting units 121 are symmetrically distributed, which is conducive to mechanical balance and posture stability during the reciprocating process, and reduces the noise caused by a single tilt angle.

[0036] Because the two second cutting units 122 are inclined relative to the first cutting unit 121, the shaving efficiency of different directions and close-fitting beards is improved, and the slippage and missed cuts are reduced.

[0037] Secondly, it can disperse and offset lateral loads, suppress the sway of the cutting blade 120, and work with the first cutting unit 121 to more easily maintain a parallel state with the outer blade 110, thereby improving the smoothness and comfort after shaving, and preventing the first cutting unit 121 from deforming during reciprocating motion.

[0038] It should be noted that the first cutting unit 121 is an arc-shaped strip, and the second cutting unit 122 is a strip inclined to the first cutting unit 121. In other embodiments, it can be other shapes, including but not limited to the shapes described above.

[0039] Preferably, the angle α between the first direction A and the second direction B is 0° < a < 180°.

[0040] Please refer to Figures 1-6 In this embodiment, the two second cutting units 122 are inclined along the first direction A and the second direction B respectively, and the included angle α between them satisfies 0°<a<180°, thereby avoiding the two second cutting units 122 being collinearly arranged, ensuring that two inclined blades with different cutting directions are formed between two adjacent first cutting units 121, thereby providing different cutting angles and cutting direction differences within the blade mesh.

[0041] By employing two second cutting units 122 arranged in two different directions, the shaving angle coverage is expanded, improving the capture and shaving efficiency of beards at different growth angles (including close-lying beards), and reducing shaving slippage and missed cuts.

[0042] Secondly, the two second cutting units 122 are arranged along the first direction A and the second direction B, which can disperse and cancel the lateral load, reduce the sway caused by the unilateral tilt angle, and help the cutting blade 120 to maintain parallel cooperation with the outer blade 110 more easily, thereby improving the smoothness and comfort after shaving.

[0043] Since the second cutting unit 122 forms a triangular structure with the two first cutting units 121 respectively, the second cutting unit 122 increases the stability between the two adjacent first cutting units 121, avoiding the problem of the first cutting unit 121 shaking or deforming during reciprocating motion.

[0044] Preferably, two second cutting units 122 are provided between two adjacent first cutting units 121, and the two second cutting units 122 are arranged in parallel.

[0045] Please refer to Figures 1-6 In this embodiment, two second cutting units 122 are arranged between two adjacent first cutting units 121, and the two second cutting units 122 are arranged in parallel.

[0046] Since the two second cutting units 122 are arranged in parallel, two inclined cutting edges with consistent direction and controllable spacing are formed between two adjacent first cutting units 121, which are used to provide a continuous and unidirectional shaving angle in the gap area, thereby cooperating with the linear cutting of the first cutting unit 121 to achieve synergistic cutting.

[0047] Two parallel second cutting units 122 are arranged between two adjacent first cutting units 121, which can increase the density and effective length of the same-direction cutting edge in the gap area, increase the efficiency of entering and shaving beards in the same or similar direction, and share the local load and reduce resistance fluctuations during the cutting process, which is conducive to improving beard cutting efficiency and post-shave smoothness; at the same time, since the geometric relationship of the two cutting edges is parallel, the consistency of their processing and assembly is easier to control, which is convenient for processing.

[0048] Secondly, by setting a second cutting unit 122 between two adjacent first cutting units 121, the stability of the first cutting unit 121 is improved, and the deformation and shaking of the first cutting unit 121 during high-speed reciprocating motion are avoided, which would affect the shaving effect.

[0049] Preferably, the two sets of second cutting units 122 on both sides of any first cutting unit 121 are arranged symmetrically with respect to the first cutting unit 121.

[0050] Please refer to Figures 1-6 In this embodiment, the second cutting unit 122 located on one side of the first cutting unit 121 is inclined along the first direction A, and the second cutting unit 122 located on the other side is inclined along the second direction B. The first direction A and the second direction B are symmetrical to each other, so that the second cutting unit 122, the first cutting unit 121, and the second cutting unit 122 are arranged in a mirror shape with the first cutting unit 121 as the axis of symmetry.

[0051] This ensures that the cutting directions of the second cutting units 122 on both sides of the first cutting unit 121 are balanced. Regardless of which side of the first cutting unit 121 the beard comes from, or whether the beard is closer to the first direction A or the second direction B, it can be captured and cut by the corresponding second cutting unit 122 on the side that is closer. At the same time, the tilt direction on both sides is symmetrical with the load direction, which is conducive to balancing the lateral force and stabilizing the posture of the cutting blade net 120 during reciprocating motion.

[0052] Two sets of second cutting units 122 on both sides of any first cutting unit 121 are symmetrically arranged with respect to the first cutting unit 121, thereby expanding and balancing the angle at which the beard enters from both sides, reducing slippage and missed cuts, and improving shaving efficiency and smoothness after shaving.

[0053] By suppressing sway and posture fluctuations through mechanical symmetry, the cutting blade 120 is more likely to maintain parallel alignment with the outer blade 110, improving smoothness and comfort.

[0054] Preferably, between two adjacent first cutting units 121, the two first cutting units 121 form a cutting space 120a, and the two second cutting units 122 are used to divide the cutting space 120a into a first cutting space 120b and a second cutting space 120c.

[0055] Please refer to Figures 1-6 In this embodiment, a cutting space 120a is formed in the blade plane by two adjacent first cutting units 121. Two second cutting units 122 are arranged in the cutting space 120a and are used to divide the cutting space 120a into a first cutting space 120b and a second cutting space 120c.

[0056] Thus, three independent spaces (two first cutting spaces 120b and one second cutting space 120c) separated from each other and with controlled angles are obtained in the same gap area, which cooperate with the adjacent first cutting unit 121 and the corresponding second cutting unit 122 to complete the entry and cutting of the beard.

[0057] The original single cutting space 120a is divided into a first cutting space 120b and a second cutting space 120c, so that the whiskers can be guided to a more suitable edge area after entering the gap.

[0058] This allows the cutting process on both sides to proceed in parallel within different spaces, reducing mutual interference and congestion between the beard and the blade edge, and improving shaving efficiency.

[0059] Preferably, the two second cutting units 122 and the two first cutting units 121 are arranged to form the second cutting space 120c.

[0060] Please refer to Figures 1-6 In this embodiment, the second cutting space 120c is defined within the blade mesh by the first cutting unit 121 on both sides and the two second cutting units 122 arranged in the middle, and the remaining area is the first cutting space 120b.

[0061] During shaving, some of the beard hairs are guided into the second cutting space 120c, forming a matching cutting pair with the inclined cutting edge of the second cutting unit 122 and / or the first cutting unit 121; another part of the beard hairs are cut in the first cutting space 120b in cooperation with the second cutting unit 122 and / or the first cutting unit 121, thereby forming two relatively independent but cooperative cutting paths between two adjacent first cutting units 121.

[0062] On the one hand, the beard entering the gap is orderly diverted and constrained between the second cutting space 120c and the first cutting space 120b, reducing disorderly interference between the beard and the blade edge; on the other hand, both spaces can establish effective cutting pairs with the first cutting unit 121 / the second cutting unit 122, ensuring that beards in different directions and in a close-fitting state are shaved nearby.

[0063] Preferably, the cutting blade 120 reciprocates relative to the outer blade 110 along a third direction C, the cutting direction of the first cutting unit 121 is perpendicular to the third direction C, and the cutting direction of the second cutting unit 122 is inclined relative to the third direction C.

[0064] Please refer to Figures 1-6 In this embodiment, the cutting direction of the first cutting unit 121 is set to be perpendicular to the third direction C, which can form a stable and predictable reference shear in the main relative direction of the reciprocating motion.

[0065] Meanwhile, the cutting direction of the second cutting unit 122 is set to an inclined direction relative to the third direction C, providing a cutting edge different from the reference direction under the same reciprocating conditions, which is used to supplement when the beard angle is unfavorable or the posture fluctuates, so as to improve shaving efficiency.

[0066] When the force changes due to the reciprocating motion of the third party towards C, the second cutting unit 122, which is set at an angle, compensates for the reference shearing, making it easier to maintain the parallel cooperation between the cutting blade net 120 and the outer blade net 110, stabilizing the cutting effect, and preventing the first cutting unit 121 from shaking or deforming.

[0067] Preferably, the second cutting unit 122 is a straight line, a broken line, or a curve.

[0068] Please refer to Figures 1-6 In this embodiment, the linear second cutting unit 122 has its cutting edge extending along a straight line, forming a straight and inclined combination of the first cutting unit 121, the second cutting unit 122, and the third cutting unit with two adjacent first cutting units 121. Its length, pitch, and relative angle with the first cutting unit 121 are determined according to the cutter head size.

[0069] It provides a stable and continuous linear cutting edge, which facilitates uniform shearing with the 110 holes of the outer blade foil, making it easy to process and assemble, and comprehensively improving shaving efficiency and post-shave smoothness.

[0070] The second cutting unit 122 is composed of two or more line segments that are connected by turning at the beginning and end. It can be V-shaped, W-shaped or multi-folded. The whole is still inclined to the first cutting unit 121. The position of the turning point and the size of the turning angle can be set as needed.

[0071] The turning point (the point of inflection) forms a local entry point and engagement point during the reciprocating process, which helps to draw the beard that is lying flat or in an unfavorable direction to the edge of the blade, while each line segment provides continuous shearing within a range of different angles.

[0072] It increases the probability of whiskers entering and being cut, reduces blade slippage and missed cuts, and alleviates the stress concentration of a single linear blade edge by distributing the load in multiple segments, thus balancing efficiency and smoothness.

[0073] Curved second cutting unit 122: The cutting edge of the second cutting unit 122 extends along a continuous curve, which can be an arc, spline or compound curve. The curvature can be constant or segmented. The whole is still inclined relative to the first cutting unit 121.

[0074] The curved edge provides gradually varying local angles and contact lengths along the length direction, making it easier for the beard to obtain the appropriate shear edge in different positions and making the force transition smoother.

[0075] It offers a gentler cut, lower resistance peaks, smoother skin contact, and greater adaptability to different beard directions and lengths, comprehensively improving shaving efficiency, post-shave smoothness, and comfort.

[0076] Preferably, the reciprocating shaver head 100 with reinforcing ribs further includes: A drive connector 130 is disposed within the mounting cavity 110a, and the cutting blade 120 is disposed on the side of the drive connector 130 near the outer blade 110.

[0077] Please refer to Figures 1-6 In this embodiment, during assembly, the drive connector 130 is connected to the drive source (such as an eccentric mechanism, the output end of a vibration motor, etc.) to drive the cutting blade 120 to reciprocate relative to the outer blade 110; the cutting blade 120 and the outer blade 110 maintain a working gap so that the two cooperate as a cutting pair to complete the beard cutting.

[0078] By placing the drive connector 130 within the mounting cavity 110a and positioning the cutting blade 120 on the side closer to the outer blade 110, the drive, guide, and position functions can be integrated within a limited cavity.

[0079] On the one hand, the driving force is effectively transmitted to the cutting blade mesh 120, and on the other hand, the movement path and end position of the cutting blade mesh 120 are limited by the connecting member, thereby stabilizing the working gap and reducing posture fluctuation.

[0080] The drive connector 130 is fixedly connected to the cutting blade net 120, improving drive transmission efficiency and responsiveness, and reducing idle travel and energy loss. It stabilizes the relative position of the cutting blade net 120 and the outer blade net 110, facilitating a basic parallel fit, reducing bending or tilting tendencies caused by resistance, and improving shearing stability.

[0081] It should be noted that the drive connector 130 is roughly a frame-shaped structure.

[0082] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
