Description

Technical Field

[0001] This utility model relates to the technical field of shavers, specifically to a blade head adaptive oscillation assembly and a shaver. Background Technology

[0002] Electric shavers are mainly divided into two categories: reciprocating and rotary. Reciprocating electric shavers typically consist of an outer foil, an inner blade assembly, a drive motor, a floating support mechanism, and a housing. During use, the outer foil conforms to the skin and advances along the face, with the beard hairs entering the openings of the outer foil. The drive motor drives the inner blades to perform high-frequency reciprocating motions on the back of the outer foil, using the shearing action formed by the edges of the outer foil openings and the inner blade edges to cut the beard. For ease of maintenance, some products incorporate a self-cleaning mechanism within the housing, which uses reciprocating motion or vibration to generate fluid disturbance, thereby cleaning the shaver head cavity and removing debris.

[0003] However, existing reciprocating electric shavers still have significant shortcomings in practical use. Firstly, because the outer foil has a mesh-like limiting structure, during the close-fitting and pushing process, some hairs are pressed down by the outer foil and trapped between the outer foil and the skin. The proportion of hairs that can enter the mesh holes for cutting is relatively low, resulting in the need for multiple back-and-forth shavings to achieve the desired shave, and thus low shaving efficiency.

[0004] Secondly, the geometric features of the face, such as the chin and jawline, are complex, and the direction of beard growth varies greatly in these areas. Users often need to frequently adjust the angle of the razor and the direction of shaving to maintain an effective fit, which can easily lead to missed shaves and residue.

[0005] Third, existing self-cleaning solutions mostly use independent cleaning components set on the outside of the blade net or inside the housing, and require dedicated space for them, which increases the overall size and structural complexity of the machine, restricts its placement, and reduces its portability and ease of use.

A swing plate is slidably installed inside the housing, and the second rotating column is connected to the swing plate in a transmission manner; the sliding direction of the swing plate is perpendicular to the axial direction of the second rotating column; The swing plate slides to drive the second rotating column to swing, thereby causing the connecting plate to rotate around the first rotating column, which in turn causes the cutter head assembly to deflect at a small angle around the first rotating column within the housing.

[0009] Preferably, the adaptive oscillation assembly of the cutting head further includes: A suspension component is installed inside the housing, and the first rotating column is rotatably connected to the suspension component.

[0011] Preferably, the levitation component further includes: The elastic plate includes a fixed part and a surrounding part. The fixed part is mounted on the mounting bracket, and the surrounding part is wound from the end of the fixed part away from the mounting bracket to form a planar spiral structure.

[0012] Preferably, the adaptive oscillation assembly of the cutting head further includes a first oscillation assembly disposed within the housing, the first oscillation assembly comprising: A oscillating magnetic component is disposed on the oscillating plate; The first magnetic change element is coupled to the oscillating magnetic element; The first magnetic variable element generates an alternating magnetic field to drive the oscillating magnetic element to move, thereby causing the oscillating plate to reciprocate and change the angle between the cutter head assembly and the housing.

[0013] Preferably, the adaptive oscillation assembly of the cutting head further includes a second oscillation assembly disposed within the housing, the second oscillation assembly comprising: An annular plate has an eccentric groove at one end and is rotatably connected to the swing plate at the other end. The annular plate is rotatably connected to the housing. An eccentric cam is housed within the eccentric groove; A drive motor is connected to the eccentric cam transmission.

[0014] Preferably, the adaptive oscillation assembly of the cutting head further includes a third oscillation assembly disposed within the housing, the oscillation plate having a third rotating column, the housing having a flexible sheet, and the third oscillation assembly comprising: The connecting rod has a movable through groove at one end and extends through the flexible sheet to the other side of the flexible sheet at the other end. One end of the third rotating column is housed in the movable through groove. An eccentric wheel is rotatably connected to the connecting rod on one side. A drive motor is connected to the eccentric wheel via a transmission.

[0015] Preferably, the adaptive oscillation assembly of the cutting head further includes: A transmission component is disposed within the housing. One end of the transmission component is connected to the cutter head assembly, and the other end is provided with a receiving groove. An elastic plate is provided between the transmission component and the mounting bracket, and both ends of the elastic plate are connected to the transmission component and the mounting bracket. A reciprocating magnetic component is disposed within the receiving groove; The second magnetic variable element is coupled to the reciprocating magnetic element; The second magnetic variable element generates an alternating magnetic field to drive the reciprocating magnetic element to move, thereby driving the transmission element to move back and forth, so that the cutter head assembly moves back and forth within the housing.

[0016] Preferably, the swing plate and / or the transmission component are provided with guide holes, and the housing is provided with guide grooves corresponding to the guide holes; The adaptive oscillation component of the cutting head also includes: The guide ball is partially housed in the guide hole and extends into the guide groove, where it is rolled into the housing.

[0017] A razor comprising an adaptive oscillation head assembly as described in any of the preceding claims, the razor further comprising: The silicone component is located on the side of the suspension assembly away from the cutter head assembly.

[0018] Preferably, the cutter head assembly includes: The outer blade mesh, the end of which is rotatably connected to the suspension assembly via a first rotating column; The cutting head is located inside the outer blade net and is connected to the transmission component. A cleaning groove is provided inside the cutting head. The self-cleaning component has one end fixed to the cutting head and the other end extending into the cleaning groove; During cleaning, the transmission component moves to drive the cutting head, causing the self-cleaning component to vibrate at high frequency in the cleaning tank, thereby generating negative pressure in the cleaning tank to draw the cleaning liquid into the cleaning tank.

[0019] The adaptive oscillation component of the razor head and the razor proposed in this utility model have the following beneficial effects: 1. The adaptive oscillating component and shaver proposed in this utility model use mechanical or magnetic drive to drive the oscillating component to output displacement or torque. Through motion conversion, the shaver head component is driven to generate a small angle of pitch deflection around a fixed or equivalent rotation center. This causes the angle between the shaver head component and the housing to be swept at high frequency during the shaving process (the angle can be adjusted between 2 and 30 degrees), so that the shaver head component can fit in close contact with the skin of the face for deep shaving.

[0020] Secondly, by tilting the blade head assembly at a small angle, the probability of the beard being captured by the blade head assembly is increased, increasing the probability of the beard entering the blade head assembly, increasing the proportion of the beard entering the mesh and reducing the number of back shavings, thereby improving the cleanliness and efficiency of one shave, reducing the burden on the user's wrist adjustment, and reducing missed shaves and residual beard.

[0021] 2. The adaptive oscillating razor head assembly and razor proposed in this utility model have an elastic plate disposed between the transmission component and the mounting bracket. This allows the transmission component to generate additional micro-strokes without changing the mechanism. The elastic plate enables stroke maintenance / amplification under low power consumption and provides buffering at the reciprocating end to suppress metal impact. This allows the razor head assembly to achieve a larger effective reciprocating sweep, effectively expanding the shaving area and improving coverage of dense / fallen beard hairs.

[0022] 3. The adaptive oscillating component and shaver proposed in this utility model, in the whole-machine cleaning mode, the transmission component drives the cutting head to reciprocate at high frequency within the outer blade screen, and the self-cleaning component fixed on the cutting head (one end fixed to the cutting head, the other end extending into the cleaning tank) subsequently generates high-frequency micro-vibration. A fixed cavity is formed between the self-cleaning component and the wall of the cleaning tank. When the free end of the self-cleaning component leaves the tank wall and the instantaneous volume of the cavity increases, an instantaneous negative pressure is formed in the cleaning tank. The negative pressure draws the cleaning liquid in the housing into the cleaning tank through the liquid inlet micro-hole / guide channel connected to the tank body. Attached Figure Description

[0025] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0026] 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.

[0027] 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.

[0028] This utility model provides a cutter head adaptive oscillation assembly 10, comprising: The housing 100 has an opening 101; The cutter head assembly 102 is installed inside the housing 100 and extends through the opening 101 to the outside; The swing assembly 103 is installed inside the housing 100 and is connected to the cutter head assembly 102 in a transmission manner; The swing assembly 103 is driven by mechanical or magnetic force to move, thereby causing the cutter head assembly to deflect at a small angle around the first rotating column 102 within the housing 100, thereby changing the angle between the cutter head assembly 102 and the housing 100.

[0029] Please refer to Figures 1-8 In this embodiment, the opening 101 of the housing 100 is opened upward, the blade assembly 102 is installed inside the housing 100 and is exposed through the upward opening 101 to contact the skin, and the swing assembly 103 is disposed inside the housing 100 and is connected to the blade assembly 102 in a transmission manner.

[0030] The oscillating component 103 outputs displacement or torque, which drives the blade head component 102 to generate a small angle of pitch deflection around a fixed or equivalent rotation center via motion conversion. This causes the included angle between the blade head component 102 and the housing 100 to be swept at a high frequency during the shaving process (the angle can be adjusted between 2 and 30 degrees), so that the blade head component 102 can fit in close to the skin of the face for a deep shave.

[0031] Secondly, by tilting the head assembly 102 at a small angle, the probability of the beard being captured by the head assembly 102 is increased, increasing the probability of the beard entering the head assembly 102, increasing the proportion of the beard entering the mesh and reducing the number of back shavings, thereby improving the cleanliness and shaving efficiency in one go, reducing the burden on the user's wrist adjustment, and reducing missed shavings and residual beard.

[0032] It should be noted that the housing 100 is roughly composed of an open hemispherical shell and a sealed rectangular shell. The hemispherical shell is used to house the cutter head assembly 102, and the swing assembly 103 is partially placed in the hemispherical shell and partially placed in the rectangular shell.

[0033] It should be noted that the transmission connection between the swing assembly 103 and the cutter head assembly 102 includes soft connection (connected by spring or silicone), hard connection (connected by connecting rod, motor, etc.) and floating connection (connected by magnetic levitation), including but not limited to the above connection methods.

[0034] Within a single cutter head assembly 102 (i.e., a single cutter head assembly 102 contains only an outer blade net 134 and a cutting blade 135), the position of the cutter head assembly 102 in the center of the housing 100 (i.e., the position of the cutter head assembly 102 perpendicular to the bottom wall inside the housing 100) can be deflected relative to one side of the housing 100 within an angle range of 2° to 45°.

[0035] It should be noted that if the rotation angle of the blade assembly 102 is less than 2 degrees, it will be difficult to fit the complex face better; if it is greater than 45 degrees, it will damage the stability of the blade assembly 102.

[0036] Preferably, the oscillating component 103 includes: A connecting plate 104 is located inside the housing 100. One side of the connecting plate 104 is mounted on the cutter head assembly 102, and the other side protrudes in a direction perpendicular to its plane to form a first rotating column 105. The first rotating column 105 is rotatably mounted inside the housing 100. The side of the connecting plate 104 away from the first rotating column 105 protrudes to form a second rotating column 106. A swing plate 107 is slidably installed inside the housing 100, and the second rotating column 106 is connected to the swing plate 107 in a transmission manner; the sliding direction of the swing plate 107 is perpendicular to the axial direction of the second rotating column 106. The swing plate 107 slides to drive the second rotating column 106 to swing, thereby driving the connecting plate 104 to rotate around the first rotating column 105, thereby driving the cutter head assembly 102 to deflect at a small angle around the first rotating column 105 within the housing 100.

[0037] Please refer to Figures 1-8 In this embodiment, the connecting plate 104 is located inside the housing 100. One side of the connecting plate 104 is fixed to the cutter head assembly 102, and the other side protrudes integrally along the normal direction of the plane of the connecting plate 104 to form a first rotating column 105, which is used as the fulcrum for rotation and is rotatably connected to the suspension shell 111. The suspension shell 111 is magnetically levitated by the mutually repulsive magnetic element 115 on the mounting bracket 114. The connecting plate 104 is rotatably connected to the swing plate 107, and the swing plate 107 is elastically connected to the mounting bracket 114 by the elastic plate 116.

[0038] The swing plate 107 is slidably installed inside the housing 100, and its sliding direction is perpendicular to the axis of the second rotating column 106. The side of the swing plate 107 near the connecting plate 104 is recessed inward to form a movable groove. The second rotating column 106 is located in the movable groove. When the swing plate 107 slides linearly under the guide constraint, it drives the second rotating column 106 to swing relative to the movable groove of the swing plate 107, thereby driving the connecting plate 104 to rotate around the first rotating column 105 at a small angle, thereby driving the cutter head assembly 102 to deflect at a small angle relative to the housing 100, realizing high-frequency swing of the cutting angle of the cutter head assembly 102.

[0039] The swing plate 107 drives the second rotating column 106 to swing, which in turn drives the connecting plate 104 to rotate around the first rotating column 105, thus efficiently and controllably converting linear displacement into pitch angle adjustment of the cutter head assembly 102.

[0040] Angle adaptation is achieved within the housing 100 to solve the problems of misalignment and angle finding in areas with large curvature. On the other hand, by continuously and subtly correcting the angle, the relative angle of attack between the outer blade mesh 134 and the whiskers is changed, increasing the probability of critical whiskers entering the blade assembly 102, fundamentally improving the problems of being pressed down by the mesh surface and low entry rate.

[0041] The high-frequency sweeping of the blade assembly 102 increases the proportion of beard hair entering the mesh, reduces the number of back-shavings, and improves the cleanliness and efficiency of a single shave.

[0042] In areas with high curvature, such as the chin and jawline, the shaving head assembly 102 can automatically follow at a small angle, eliminating the need for users to frequently change wrists to find the angle, reducing missed shaves and residue, and improving operating comfort.

[0043] It should be noted that the connecting plate 104 is roughly semi-circular in shape, with a first rotating post 105 protruding from one side and a second rotating post 106 protruding from the other side. Both the first rotating post 105 and the second rotating post 106 are cylindrical. The swing plate 107 is a plate with one end roughly shaped like a "mountain" and the other end being a rectangular plate. The axes of the first rotating post 105 and the second rotating post 106 are aligned, with the axis of the first rotating post 105 aligned with the reciprocating motion direction of the cutter head assembly 102.

[0044] It should be noted that the second rotating column 106 is connected to the swing plate 107 in a transmission connection. The transmission connection methods include soft connection (i.e., installing a spring or silicone (elastic deformation element) in the movable groove of the swing plate 107, and connecting the second rotating column 106 or the connecting plate 104 on the other side of the elastic deformation element), hard connection (driving by a drive motor), and floating connection (connecting by magnetic levitation), including but not limited to the above connection methods.

[0045] Preferably, the adaptive oscillation assembly of the cutting head further includes: The suspension component 110 is installed inside the housing 100, and the first rotating column 105 is rotatably connected to the suspension component 110.

[0046] Please refer to Figures 1-8 In this embodiment, the displacement or torque output by the swing assembly 103 is transmitted to the first rotating column 105 via the second rotating column 106 and the connecting plate 104. The suspension assembly 110 provides low-friction, low-hysteresis rotational support and slight vibration isolation, enabling the cutter head assembly 102 to achieve small-angle, continuous and controllable deflection relative to the housing 100.

[0047] Meanwhile, the suspension component 110 provides a barrier and energy dissipation path for the high-frequency reciprocating excitation of the cutting head 135, suppressing the vibration from being directly coupled to the housing 100, thereby ensuring a linear and repeatable response to small-angle deflection and stable mechanical accuracy.

[0048] By significantly reducing fulcrum friction and hysteresis, the input of the oscillating component 103 is precisely and smoothly converted into a small-angle deflection of the cutter head, resulting in more delicate angle control.

[0049] Preferably, the levitation component 110 includes: The suspension shell 111 has a rotating hole 112, which is rotatably connected to the first rotating column 105. The levitation magnetic component 113 is installed inside the levitation shell 111; Mounting bracket 114 is installed inside the housing 100, and the mounting bracket 114 is elastically connected to the cutter head assembly 102; A mutually repulsive magnetic component 115 is mounted on the mounting bracket 114, and the magnetic pole of the mutually repulsive magnetic component 115 near the levitation magnetic component 113 is mutually repulsive to the levitation magnetic component 113.

[0050] Please refer to Figures 1-8In this embodiment, the suspension assembly 110 includes a suspension shell 111 integrally formed or assembled. The suspension shell 111 has a rotation hole 112 that cooperates with the first rotating column 105, which is used to provide low-friction rotational support for the first rotating column 105 on the connecting plate 104. A suspension magnetic element 113 is fixedly installed inside the suspension shell 111 or its side cavity. A mounting bracket 114 is also assembled inside the housing 100. The mounting bracket 114 is elastically connected to the cutter head assembly 102, and a repulsive magnetic element 115 that repels the suspension magnetic element 113 is fixedly installed on the mounting bracket 114.

[0051] During operation, the displacement / torque output by the oscillating assembly 103 is transmitted to the first rotating column 105 via the second rotating column 106 and the connecting plate 104, achieving low-friction rotation through the rotating hole 112 of the suspension shell 111. Simultaneously, a non-contact preload and magnetic spring effect are formed between the suspended magnetic component 113 and the mutually repulsive magnetic component 115. Firstly, it provides compliant support and centering force along the radial / axial direction, which, combined with the elastic connection of the mounting bracket 114 to the cutter head assembly 102, buffers and centers the micro-displacement of the first rotating column 105. Secondly, the superimposed magnetic repulsion preload eliminates the gap backlash and start-stop stickiness of traditional rigid hinge points, allowing small-stroke inputs to be continuously and linearly converted into small-angle deflection of the cutter head.

[0052] To suppress stray magnetic flux and stabilize the magnetic force curve, a soft magnetic yoke (low-carbon steel / pure iron) can be placed on the back of the magnet to form a closed magnetic circuit.

[0053] The first rotating column 105 is equipped with non-contact preload and adjustable magnetoelasticity by adopting the elastic connection of the suspended shell 111 / rotation hole 112, the suspended magnetic component 113 and the mutually repulsive magnetic component 115, and the mounting bracket 114. This significantly reduces the start-stop viscosity and angular hysteresis caused by the friction and gap of the traditional rigid support, so that smooth and repeatable small-angle deflection can be achieved even with minimal input displacement.

[0054] The parallel combination of magnetic repulsion and elastic support is equivalent to a suitable hardness, which can filter out the high-frequency vibration brought by the cutting head 135 and reduce noise, while also providing the necessary centering and posture stability, and improving the conformal fit of the cutting head to the large curvature of the face.

[0055] It should be noted that the suspension shell 111 is roughly rectangular, the rotating hole 112 is a round hole, the suspension magnetic component 113 is a magnet, the mounting bracket 114 is an elliptical frame structure, and the hollow part in the middle is used to install the cutter head assembly 102, and the mutually repulsive magnetic component 115 is a magnet.

[0056] It should be noted that, in order to suppress stray magnetic flux and stabilize the magnetic force curve, a soft magnetic yoke (low carbon steel / pure iron) can be set on the back of the mutually repulsive magnetic component 115 magnet to form a closed magnetic circuit.

[0057] Preferably, the levitation component 110 further includes: The elastic plate 116 includes a fixing part 117 and a surrounding part 118. The fixing part 117 is mounted on the mounting bracket 114. The surrounding part 118 is wound from the end of the fixing part 117 away from the mounting bracket 114 to form a planar spiral structure. The free end of the surrounding part 118 is fixedly connected to the swing plate 107.

[0058] Please refer to Figures 1-8 In this embodiment, the suspension component 110 includes an elastic plate 116. The elastic plate 116 is integrally formed by a fixing part 117 and a surrounding part 118. The fixing part 117 is installed on the mounting bracket 114 by means of screws / rivets / hooks or rubber inserts. The surrounding part 118 is formed by circumferentially winding from the end of the fixing part 117 away from the mounting bracket 114. The surrounding part 118 is located in a plane parallel to the swing plate 107 and is in the form of a planar spiral (such as an Archimedean spiral or an approximately concentric circle).

[0059] In the sliding direction of the swing plate 107, the surrounding part 118 provides an approximately linear restoring force in the form of a planar helical spring, so that the small stroke input of the swing plate 107 is transmitted seamlessly to the connecting plate 104 and the first rotating column 105, ensuring that the small angle deflection of the cutter head assembly 102 is continuous and repeatable.

[0060] Meanwhile, the surrounding part 118 has limited deformation in the plane, which effectively expands the effective range of motion of the mounting bracket 114 along the sliding direction. Since the head assembly 102 is mounted on the mounting bracket 114, the coordinated flexibility of the mounting bracket 114, the elastic plate 116, and the swing plate 107 enables the head to achieve a small angle of pitch while obtaining slight translational compensation, thereby increasing the effective shaving coverage of the head assembly 102.

[0061] The in-plane elasticity provides near-linear restoring force, significantly reducing transmission chain backlash and enabling even minimal displacement to be smoothly converted into small-angle deflection, thus improving angle control precision.

[0062] The in-face conformal fit of the mounting bracket 114 allows the shaving head to achieve slight translational compensation while tilting up and down, expanding the effective shaving coverage and improving the fit and whisker capture in areas with large curvature such as the chin / jawline.

[0063] It should be noted that the elastic plate 116 is roughly a metal spring, the fixing part 117 is roughly a rectangular plate, and the surrounding part 118 is roughly a spiral plate.

[0064] Preferably, the adaptive oscillation assembly of the cutting head further includes a first oscillation assembly 119 disposed within the housing 100, the first oscillation assembly 119 comprising: A swing magnetic component 120 is disposed on the swing plate 107; The first magnetic change element 121 is coupled to the oscillating magnetic element 120; The first magnetic variable element 121 generates an alternating magnetic field to drive the oscillating magnetic element 120 to move, thereby causing the oscillating plate 107 to reciprocate, thereby changing the angle between the cutter head assembly 102 and the housing 100.

[0065] Please refer to Figures 1-8 In this embodiment, a first swing component 119 is provided on the swing structure inside the housing 100, a swing magnetic component 120 (which may be a permanent magnet or a soft magnet) is fixed on the swing plate 107, and a first magnetic change component 121 magnetically coupled to it is provided in the vicinity of the swing plate 107.

[0066] The oscillating magnetic component 120 is made of small NdFeB permanent magnets (such as N35 to N48, with a size of 3 to 8 mm), and is fixed to the oscillating plate 107 by means of embedding groove, adhesive or plastic sealing.

[0067] The first magnetic change element 121 is an electromagnetic coil fixed on the housing 100 or the support frame. The back of the coil is equipped with a soft magnetic yoke / pole shoe (low carbon steel or pure iron) to form a closed magnetic circuit and suppress magnetic leakage.

[0068] The control circuit applies an alternating current (sine wave, square wave, or PWM equivalent) to the coil. The alternating magnetic field generated by the coil interacts with the oscillating magnetic component 120, applying a periodic pushing / pulling force to the oscillating plate 107 along its linear guiding direction, causing the oscillating plate 107 to reciprocate linearly under the constraint of the guide pair.

[0069] The linear displacement is converted into a small-angle deflection of the cutter head assembly 102 relative to the housing 100 via the second rotating column 106, the connecting plate 104, and the first rotating column 105, thereby continuously changing the included angle between the cutter head assembly 102 and the housing 100.

[0070] The contactless force of electromagnetic drive avoids the backlash and wear of traditional eccentric / connecting rods, and achieves low friction and low backlash output with preload and guidance; repeatable micro displacement can be obtained by changing the current, so that the cutter head assembly 102 sweeps at high frequency during the movement.

[0071] Mid-frequency oscillation creates a subtle lifting or slapping effect on the mesh surface, improving the angle of attack and entry rate of the beard relative to the edge of the hole, reducing the beard being pressed down by the mesh surface, and reducing the number of times it needs to be scraped back.

[0072] Low-frequency slow-adjustment superposition enables the razor head to adaptively follow areas with large curvatures such as the chin and jawline, eliminating the need for users to frequently change wrist positions and reducing missed shaves and residue.

[0073] In another embodiment, an electromagnet-type scheme consisting of a fixed magnet, a moving iron core (moving soft magnet), and a coil can be adopted.

[0074] The oscillating magnetic component 120 has a soft magnetic core, and the first magnetic change component 121 is a coil with pole shoes. To obtain bidirectional symmetrical output, opposing double electromagnets or a magnetic bias can be set in the middle position. Regardless of whether a moving magnet or moving iron scheme is adopted, the first magnetic change component 121 generates an alternating magnetic field, which converts electrical energy into controllable reciprocating displacement of the oscillating plate 107 through a short link, and then converts it into a small-angle deflection of the cutter head through a mechanism. It is also decoupled from the main cutting drive and does not occupy space with it.

[0075] It should be noted that the oscillating magnetic component 120 is a magnet, and the first magnetic change component 121 is a magnetic induction coil.

[0076] Preferably, the adaptive oscillation assembly of the cutting head further includes a second oscillation assembly 122 disposed within the housing 100, the second oscillation assembly 122 comprising: The annular plate 127 has an eccentric groove 127a at one end and is rotatably connected to the swing plate 107 at the other end. The annular plate 127 is rotatably connected to the housing 100. An eccentric cam 123 is housed within the eccentric groove 127a; The drive motor 124 is connected to the eccentric cam 123 for transmission.

[0077] Please refer to Figures 12-13 In this embodiment, during operation, the motor drives the eccentric cam 123 to rotate, causing the eccentric cam 123 to generate a thrust on the annular plate 127 within the eccentric groove 127a. Since the annular plate 127 is rotatably connected to the housing 100, and the middle part of the annular plate 127 is rotatably connected to the housing 100 via the positioning post 1002, the annular plate 127 will deflect at a small angle relative to the housing 100, thereby driving the swing plate 107 to reciprocate linearly, causing the swing plate 107 to reciprocate at a constant amplitude along the guide direction. This linear displacement is converted into a small-angle periodic deflection of the blade assembly 102 relative to the housing 100 via the kinematic chain of the second rotating post 106, the connecting plate 104, and the first rotating post 105, thereby continuously and frequently sweeping the angle between the blade assembly 102 and the skin during the shaving process.

[0078] The motor and eccentric cam 123 directly convert the rotation into the linear reciprocating motion of the swing plate 107. The force path is short, the efficiency is high, the response is fast, and the hysteresis is small, which makes it easy to achieve stable small-angle deflection output in a limited space.

[0079] Continuous small-angle deflections create a gentle lifting or slapping effect on the mesh surface, making the angle of attack of the beard against the edge of the razor mesh more favorable, reducing the beard being pressed down by the mesh surface, thereby reducing back-shaving and improving the cleanliness of a single shave; at the same time, it provides continuous angle compensation for areas with large curvatures such as the chin and jawline, reducing missed shaves.

[0080] It should be noted that the eccentric cam 123 is an eccentric cylindrical shape, and the drive motor 124 is a motor, eccentric motor, rotary motor, servo motor, geared motor, etc., including but not limited to the above types of motors. The annular plate 127 and the swing plate 107 are connected by a sealing elastic element. One end of the sealing elastic element is spherical and the other end is corrugated. Through the elastic connection, the swing plate 107 is driven to reciprocate relative to the housing 100. The sealing elastic element is made of silicone material.

[0081] It should be noted that the drive motor 124 is installed inside the housing 100 or on the handle 100, including but not limited to the above-mentioned installation methods and positions. Furthermore, the second swing assembly 122 is at least one set, including but not limited to one, two, three, or four sets, and its location is not limited to the end, side, corner, or bottom of the cutter head assembly 102, but includes but is not limited to the above-mentioned installation positions.

[0082] Preferably, the adaptive oscillation assembly 10 further includes a third oscillation assembly 140 disposed within the housing 100, the oscillation plate 107 having a third rotating column 1071, the housing 100 having a flexible sheet 1001, and the third oscillation assembly 140 comprising: The connecting rod 141 has a movable through groove 141a at one end and extends through the flexible sheet 1001 to the other side of the flexible sheet 1001 at the other end. One end of the third rotating column 1071 is housed in the movable through groove 141a. The eccentric wheel 142 is rotatably connected to the connecting rod 141 on one side; The drive motor 124 is connected to the eccentric wheel 142 in a transmission connection.

[0083] Please refer to Figures 9-11 In this embodiment, during operation, the drive motor 124 drives the eccentric wheel 123 to rotate. Since the eccentric wheel 123 is rotatably connected to the connecting rod 141, the connecting rod 141 moves eccentrically relative to the output shaft of the drive motor 124. Since one end of the third rotating column 1071 is housed in the movable through groove 141a, the inner wall of the movable through groove 141a will generate a thrust on the third rotating column 1071, thereby pushing the third rotating column 1071 to rotate. The rotation of the third rotating column 1071 drives the swing plate 107 to reciprocate linearly within the housing. The reciprocating linear motion of the swing plate 107 then drives the connecting plate 104 to perform a small-angle deflection motion, ultimately causing the cutter head assembly 102 to generate a high-frequency sweeping motion relative to the housing 100.

[0084] Continuous small-angle deflections create a gentle lifting or slapping effect on the mesh surface, making the angle of attack of the beard against the edge of the razor mesh more favorable, reducing the beard being pressed down by the mesh surface, thereby reducing back-shaving and improving the cleanliness of a single shave; at the same time, it provides continuous angle compensation for areas with large curvatures such as the chin and jawline, reducing missed shaves.

[0085] The connecting rod 141 is generally elliptical at one end and rod-shaped at the other. A strip-shaped movable slot 141a is provided at the elliptical end. The eccentric wheel 142 is generally circular with a protruding plate along its outer edge. The protruding plate is rotatably connected to the connecting rod 141. The center of the circular wheel 142 is rotatably connected to the output shaft of the drive motor 124. Furthermore, the third swing assembly 140 is at least one set, including but not limited to one, two, three, or four sets, and its location is not limited to the end, side, corner, or bottom of the cutter head assembly 102, but includes, but is not limited to, the aforementioned mounting positions.

[0086] It should be noted that the movement of the drive motor 124 causes the eccentric wheel 142 to drive the connecting rod 141 to move. The connecting rod 141 passes through the flexible sheet 1001 and is connected to the third rotating column 1071. Since the connecting rod 141 passes through the flexible sheet 1001, its radial direction is partially constrained by the flexible sheet 1001 during the movement, causing the drive motor 124 to drive the eccentric wheel 142 to rotate. The connecting rod 141 will deflect around the geometric center point of the flexible sheet 1001, thereby driving the swing plate 107 to reciprocate, and finally causing the cutter head assembly 102 to generate high-frequency sweeping relative to the housing 100.

[0087] Preferably, the adaptive oscillation assembly of the cutting head further includes: A transmission component 125 is disposed inside the housing 100. One end of the transmission component 125 is connected to the cutter head assembly 102, and the other end is provided with a receiving groove 126. An elastic plate 116 is provided between the transmission component 125 and the mounting bracket 114, and both ends of the elastic plate 116 are connected to the transmission component 125 and the mounting bracket 114. A reciprocating magnetic component 128 is disposed within the receiving groove 126; The second magnetic variable element 129 is coupled to the reciprocating magnetic element 128; The second magnetic variable element 129 generates an alternating magnetic field to drive the reciprocating magnetic element 128 to move, thereby driving the transmission element 125 to reciprocate, so that the cutter head assembly 102 reciprocates within the housing 100.

[0088] Please refer to Figures 1-8 In this embodiment, a transmission member 125 for driving the cutting head 135 to reciprocate is provided inside the housing 100. The front end (or upper end, the orientation is not limited below) of the transmission member 125 is detachably connected to the cutting head 135 in the head assembly 102 by means of a fork pin, dovetail, or sliding tenon, and the rear end is machined with a receiving groove 126 extending along its axis. The cross-section of the receiving groove 126 can be an elongated hole or a U-shaped cavity, used to accommodate and guide the reciprocating magnetic member 128.

[0089] An elastic plate 116 is provided between the transmission component 125 and the mounting bracket 114. The two ends of the elastic plate 116 are fixed to the transmission component 125 and the mounting bracket 114 respectively. The elastic plate 116 is preferably a stainless steel / phosphor bronze leaf spring, which provides axial restoring force and has a certain degree of compliance in the non-working direction to absorb assembly tolerances and impacts.

[0090] During operation, the control circuit applies an alternating current (sine wave, bipolar square wave, or PWM equivalent) to the second magnetic change element 129. The alternating magnetic field generated by the coil couples with the reciprocating magnetic element 128, applying a periodic pushing / pulling force along the axial direction of the transmission element 125, driving the reciprocating magnetic element 128 to move linearly within the receiving groove 126. This movement, through the rigid connection between the reciprocating magnetic element 128 and the transmission element 125 (or the guide contact with the groove wall), drives the entire transmission element 125 to move in a reciprocating linear motion.

[0091] An elastic plate 116 is disposed between the transmission member 125 and the mounting bracket 114, and its main flexible axis is consistent with the reciprocating direction of the transmission member 125. The two ends of the elastic plate 116 are fixed to the transmission member 125 and the mounting bracket 114 respectively, forming an elastic compliance and restoring force link in the reciprocating direction.

[0092] When the second magnetic change element 129 drives the reciprocating magnetic element 128, thereby driving the transmission element 125 to reciprocate along its axial direction, the elastic plate 116 provides preload and linear restoring force in the reciprocating direction, on the one hand transmitting the electromagnetic push / pull force to the cutting head 135 without gap to achieve the reciprocating stroke.

[0093] On the other hand, the transmission component 125 is allowed to generate additional micro-strokes without changing the mechanism. The elastic plate 116 achieves stroke retention / amplification with low power consumption and provides cushioning at the reciprocating end to suppress metal impact. This allows the shaving head assembly 102 to achieve greater effective reciprocating sweep, effectively expanding the shaving area and improving coverage of dense / fallen beard hairs.

[0094] It maintains more stable reciprocating output and close-fitting force when dealing with complex facial geometry and sudden load changes, reducing missed shavings and backshaving.

[0095] It should be noted that the transmission component 125 is generally axial at one end and rectangular at the other end, and a receiving groove 126 is provided on the side of the rectangular block away from the axial shape. The transmission component 125 is housed in the motion groove inside the cutting head 135. During the reciprocating motion, the transmission component 125 pushes the inner wall of the motion groove of the cutting head 135 to realize the reciprocating motion of the cutting head assembly 102.

[0096] A connecting frame is provided between the outer blade net 134 and the cutting head 135, and the outer blade net 134 and the cutting head 135 are connected together through the connecting frame.

[0097] The reciprocating magnetic component 128 is a magnet, the second magnetic change component 129 is a magnetic induction coil, and the first magnetic change component 121 and the second magnetic change component 129 are both installed in a sealed rectangular shell (the sealed rectangular shell of the housing 100).

[0098] Preferably, the swing plate 107 and / or the transmission component 125 are provided with guide holes (not shown in the figure), and the housing 100 is provided with guide grooves (not shown in the figure) corresponding to the guide holes. The adaptive oscillation component of the cutting head also includes: The guide ball (not shown in the figure) is partially housed in the guide hole and extends into the guide groove, where it is tactilely connected to the housing 100.

[0099] Please refer to Figures 1-8 In this embodiment, the swing plate 107 and / or the transmission member 125 are machined (or formed) with a plurality of guide holes, each guide hole housing a guide ball; a guide groove is integrally formed or embedded inside the housing 100 at a position corresponding to the guide hole. The outer half of the guide ball extends from the guide hole and enters the guide groove, forming a rolling contact with the groove wall, thereby providing rolling linear guidance when the swing plate 107 (or the transmission member 125) moves along a predetermined linear degree of freedom.

[0100] The rolling guidance of the balls and the groove wall significantly reduces friction and starting resistance, allowing the stroke input to be transmitted linearly and without gaps to the angle output link.

[0101] When the swing plate 107 is driven by the first swing assembly 119 (electromagnetic / eccentric) to reciprocate along the guide direction, or when the transmission component 125 is driven by the second magnetic change component 129 to reciprocate along its axial direction, the guide balls roll in the guide groove, ensuring that the movement of the swing plate 107 / transmission component 125 is strictly linear and greatly reducing stick-slip and wear, while ensuring the accuracy of the movement trajectory.

[0102] It should be noted that the guide hole is a hemispherical hole, the guide groove is a straight groove, and the guide ball is a round ball.

[0103] A razor comprising an adaptive oscillation head assembly as described in any of the preceding claims, the razor further comprising: Silicone component 133 is located on the side of the suspension assembly 110 away from the cutter head assembly 102.

[0104] Preferably, the cutter head assembly 102 includes: The outer blade mesh 134 is rotatably connected to the suspension assembly 110 via a first rotating column 105. The cutting head 135 is located inside the outer blade net 134 and is connected to the transmission component 125. A cleaning groove 136 is provided inside the cutting head 135. The self-cleaning component 137 has one end fixed to the cutting head 135 and the other end extending into the cleaning groove 136; During cleaning, the transmission component 125 moves to drive the cutting head 135 to move, so that the self-cleaning component 137 vibrates at high frequency in the cleaning tank 136 to generate negative pressure in the cleaning tank 136, so as to draw the cleaning liquid into the cleaning tank 136.

[0105] Please refer to Figures 1-8 In this embodiment, the blade assembly 102 is exposed at the upward opening 101 of the housing 100, and its end is supported and connected to the housing 100 through the suspension assembly 110.

[0106] A silicone component 133 is provided on the side of the suspension assembly 110 away from the cutter head assembly 102. The silicone component 133 is fitted or embedded between the suspension shell 111 and the shell 100 to form a continuous elastic sealing and damping path.

[0107] On the one hand, the structure provides additional axial / radial compliance and damping to the suspension component 110, reducing the hard transmission of the high-frequency excitation of the cutting mechanism to the housing 100.

[0108] On the other hand, the blade assembly 102 can deform during reciprocating motion, thereby increasing the reciprocating shaving stroke.

[0109] The cutter head assembly 102 preferably includes an outer cutter head 134, the end of which is rotatably connected to the suspension assembly 110 via a first rotating column 105 to achieve a small angle of pitch.

[0110] The shaving head assembly 102 preferably includes a cutting head 135 disposed within an outer foil 134 and connected to a transmission member 125 for shaving. To achieve self-cleaning without an external pump, one or more cleaning grooves 136 are machined or formed inside the cutting head 135, and the two ends of the cleaning grooves 136 are connected to the guide grooves / return holes in the head cavity.

[0111] A self-cleaning component 137 is also fixed on the cutting head 135. One end of the component is rigidly fixed to the cutting head 135, and the other end is inserted into the cleaning groove 136. The self-cleaning component 137 can be an elastic metal spring, an engineering plastic tongue, or a rubber-coated composite sheet. Its free end maintains a gap with the side wall of the cleaning groove 136, and it can achieve spring-type or spring-valve-type vibration during reciprocating motion.

[0112] In the whole-machine cleaning mode, the transmission component 125 drives the cutting head 135 to reciprocate at high frequency within the outer blade mesh 134. The self-cleaning component 137 fixed on the cutting head 135 (one end is fixed to the cutting head, and the other end extends into the cleaning tank 136) then undergoes high-frequency micro-vibration. A fixed cavity is formed between the self-cleaning component 137 and the wall of the cleaning tank 136. When the free end of the self-cleaning component 137 leaves the tank wall and the instantaneous volume of the cavity increases, an instantaneous negative pressure is formed in the cleaning tank 136. The negative pressure draws the cleaning liquid in the housing 100 into the cleaning tank 136 through the liquid inlet micro-hole / guide channel connected to the tank body.

[0113] When the self-cleaning component 137 returns to the center position or near the tank wall, it only mixes and agitates, without discharging liquid outward under positive pressure; the cleaning liquid carrying debris falls naturally back to the debris collection / return area of ​​the rear cavity through the overflow port / return hole under the action of gravity, inertia and shear disturbance, and is then discharged through the guide channel to achieve the self-cleaning function.

[0114] It should be noted that the silicone part 133 is roughly a "U" shaped silicone, the outer blade mesh 134 is an arc-shaped mesh, the self-cleaning part 137 is a sheet, and the cleaning groove 136 is a through groove.

[0115] 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.
