Self-cleaning magnetic suspension shaver

Abstract

According to the self-cleaning magnetic suspension shaver, during cleaning, the driving assembly generates an alternating magnetic field. A magnetic field generated by the driving assembly penetrates through the driving base and the tool bit seat and forms a magnetic coupling relation with the tool bit assembly, and non-contact driving is achieved. The tool bit assembly rotates under the action of the magnetic field and drives the negative pressure generating piece installed on the tool bit assembly to rotate synchronously. When the negative pressure generating piece rotates, a low-pressure area is formed in or around the tool bit assembly. The negative pressure area sucks external clean water or cleaning liquid into the containing cavity in the tool bit seat through physical suction force. The sucked liquid forms a certain flow path (such as vortex and flushing flow) in the containing cavity, and hair scraps on the surface and in gaps of the tool bit assembly are cleaned. And finally, sewage is discharged through a discharge hole preset in the tool bit seat, and the cleaning process is completed. Through magnetic suspension driving and a negative pressure water suction structure, sucked water flow can enter a gap between the tool bit assembly and the containing cavity, and residual hair, scurf and grease which are difficult to touch at ordinary times are cleaned.

Description

Technical Field

[0001] The present invention relates to the technical field of shavers, in particular to a self-cleaning magnetic suspension shaver. Background Art

[0002] The main purpose of a razor is to remove facial or body hair, leaving the skin smoother and neater. Traditional razors can easily scratch or cut the skin during shaving, and the shaving process is very long. Electric razors, on the other hand, are easy to operate and have a short operation time, making them popular among users.

[0003] Electric shavers are often driven by motors, which drive the blades to rotate and shave. However, during the disassembly and cleaning process, the entire blade needs to be disassembled and then cleaned. The current disadvantages of cleaning electric shavers are as follows:

[0004] 1. Disassembly and installation are difficult. During the disassembly process, all parts in the cutter head need to be removed for cleaning, which makes the disassembly and installation time very long.

[0005] 2. Inadequate cleaning. Since electric shavers are driven by motors and drive components (including drive shafts and drive gears), the drive components are fixedly mounted on the body during disassembly, making them impossible to disassemble. There is a gap between the drive component and the shaver, and once beards enter the gap, they cannot be cleaned. Long-term use will breed bacteria.

[0006] 3. It cannot be washed directly with water. Since the existing electric shavers are driven by motors, if they are cleaned directly with water, there is a risk that water will directly enter the interior of the electric shaver. Once water enters the interior of the electric shaver, the motor will be affected by the water and short-circuit, making it unable to work. Summary of the Invention

[0041] Preferably, the drive assembly further comprises:

[0042] A circuit board is arranged in the sealed cavity;

[0043] A power supply is arranged in the sealed cavity, and the circuit board is electrically connected to the induction coil and the power supply respectively.

[0044] The self-cleaning magnetic levitation shaver proposed by the present invention has the following beneficial effects:

[0045] 1. The self-cleaning magnetic levitation shaver proposed in this invention generates an alternating magnetic field through the drive assembly during cleaning. This magnetic field passes through the drive base and the cutter head holder, forming a magnetic coupling relationship with the cutter head assembly, achieving non-contact drive.

[0046] The cutter head assembly rotates under the action of the magnetic field, driving the negative pressure generating component installed thereon to rotate synchronously.

[0047] As the negative pressure generating element rotates, a low-pressure zone is created inside or around the cutter head assembly. This negative-pressure zone, through physical suction, draws clean water or cleaning fluid into the chamber within the cutter head holder. This fluid then flows through the chamber, creating a specific flow path (e.g., eddy currents or flushing currents), cleaning hair debris from the cutter head assembly surface and gaps.

[0048] Finally, the sewage is discharged through the preset discharge holes on the cutter head seat, completing the cleaning process.

[0049] Through magnetic levitation drive and negative pressure water absorption structure, cleaning can be completed without the user disassembling the shaver, greatly improving the convenience of use and daily maintenance efficiency.

[0050] The drive assembly and the cutter head assembly are completely physically isolated and coupled through a magnetic field. The drive part is sealed in a sealed cavity, effectively preventing water from entering the drive assembly part, greatly improving the safety and service life of the product.

[0051] The inhaled water flow can enter the gap between the cutter head assembly and the accommodating cavity to clean residual hair, dandruff and grease that are usually difficult to reach.

[0052] The cleaning liquid forms a vortex in the accommodating cavity, thereby increasing the flushing force and improving the cleaning efficiency.

[0053] 2. In the self-cleaning magnetic levitation shaver proposed by the present invention, when the driving assembly is working, the internal induction coil generates an alternating magnetic field, a portion of which directly passes through the magnetic permeable part and acts on the magnetic part from the driving assembly to drive it to move.

[0054] The other part of the magnetic field is reflected by the first magnetic yoke and acts on the magnetic part. The two magnetic fields are superimposed on the magnetic part to form a stronger magnetic response torque, which improves the response sensitivity of the magnetic part and realizes faster and stronger rotation drive.

[0055] More efficient magnetic flux utilization reduces power waste due to magnetic leakage loss, helping to reduce drive power consumption and improve energy utilization.

[0056] Since the combination of the first magnetic yoke and the magnetic part constitutes a high-efficiency magnetic drive system, it ensures that the entire negative pressure rotation system runs smoothly, with low noise and low vibration, which is conducive to the continuous and stable cleaning liquid suction process.

[0057] 3. The self-cleaning magnetic levitation shaver proposed by the present invention generates an alternating magnetic field around the induction coil after it is energized. A part of the magnetic field passes through the magnetic permeable path (through the first magnetic permeable surface, the second magnetic permeable surface, and the magnetic permeable part) in the positive direction and acts on the magnetic part to drive the cutting unit. The other part of the magnetic flux will diffuse and reflect toward the back side of the induction coil, forming a magnetic field superposition. The magnetic flux is looped back to form a superposition effect with the positive magnetic field, thereby enhancing the positive magnetic flux density.

[0058] The second magnetic yoke allows the magnetic field generated by the induction coil to act more concentratedly on the magnetic component, preventing the diffusion of ineffective magnetic flux. This improves the drive response sensitivity and rotational torque of the cutter head assembly, reduces energy consumption, and enhances power transmission.

[0059] The effective magnetic flux returns through the second magnetic yoke to form a complete magnetic circuit, while reducing the interference of the magnetic field on surrounding metal parts or circuits and improving electromagnetic compatibility. BRIEF DESCRIPTION OF THE DRAWINGS

[0080] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0081] It should be noted that in the description of the present invention, the terms "transverse," "longitudinal," "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer" and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed, or operate in a specific orientation, and therefore should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and the like are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0082] The present invention provides a self-cleaning magnetic suspension shaver 100, comprising:

[0083] The driving base 110 has a sealed cavity 110a formed therein;

[0084] The driving assembly 120 is disposed in the sealed cavity 110a;

[0085] The cutter head seat 130 has an accommodating cavity 130a formed therein, and a discharge hole 130b communicating with the accommodating cavity 130a is opened on the cutter head seat 130;

[0086] The cutter head assembly 140 is disposed in the accommodating cavity 130a and partially extends out of the accommodating cavity 130a. The cutter head assembly 140 is in communication with the accommodating cavity 130a.

[0087] A negative pressure generating member 150 is mounted on the cutter head assembly 140;

[0088] Among them, the driving component 120 works to generate a magnetic field to couple with the cutter head component 140 to drive the cutter head component 140 to move, and then drive the negative pressure generating component 150 to rotate to generate negative pressure, and finally the external water is sucked into the accommodating cavity 130a through the negative pressure for cleaning.

[0089] Please refer to Figures 1-9 In this embodiment, during cleaning, the drive assembly 120 generates an alternating magnetic field. The magnetic field generated by the drive assembly 120 passes through the drive base 110 and the cutter head seat 130, and forms a magnetic coupling relationship with the cutter head assembly 140, realizing non-contact driving.

[0090] The cutter head assembly 140 rotates under the action of the magnetic field, driving the negative pressure generating member 150 mounted thereon to rotate synchronously.

[0091] As the negative pressure generating element 150 rotates, a low-pressure zone is formed inside or around the cutter head assembly 140. This negative-pressure zone, through physical suction, draws clean water or cleaning fluid into the chamber 130a within the cutter head holder 130. The drawn-in fluid forms a specific flow path (e.g., eddy current or flushing flow) within the chamber 130a, cleaning the surface of the cutter head assembly 140 and any hair debris trapped in the gaps.

[0092] Finally, the sewage is discharged through the preset discharge hole 130b on the cutter head seat 130, completing the cleaning process.

[0093] Through magnetic levitation drive and negative pressure water absorption structure, cleaning can be completed without the user disassembling the shaver, greatly improving the convenience of use and daily maintenance efficiency.

[0094] The drive assembly 120 and the cutter head assembly 140 are completely physically isolated and coupled through a magnetic field. The drive part is sealed in the sealed cavity 110a, effectively preventing water from entering the drive assembly 120, greatly improving the safety and service life of the product.

[0095] The sucked water flow can enter the gap between the cutter head assembly 140 and the accommodating cavity 130a, and clean the residual hair, dandruff and grease that are usually difficult to reach.

[0096] The cleaning liquid forms a vortex in the accommodating cavity 130a, thereby increasing the flushing force and improving the cleaning efficiency.

[0097] The driving assembly 120 is disposed in the sealed cavity 110 a and is isolated from the external environment to prevent liquid from entering and ensure electrical safety.

[0098] After the self-cleaning magnetic levitation shaver 100 is started, the driving assembly 120 is powered on and starts to generate a magnetic field.

[0099] The cutter head assembly 140 is in the magnetic field action area of the driving assembly 120. The alternating magnetic field generated by the driving assembly 120 is electromagnetically coupled with the cutter head assembly 140. Under the action of the magnetic field change, the cutter head assembly 140 rotates, thereby achieving cutting of beard or hair.

[0100] When the self-cleaning magnetic suspension shaver 100 is turned off, the drive assembly 120 is no longer powered, the magnetic field disappears, and the cutter head assembly 140 is no longer attracted. At this time, there is no magnetic attraction between the cutter head holder 130 and the drive base 110, making it convenient for the user to remove the cutter head holder 130 for cleaning or replacement.

[0101] The entire drive structure, consisting of the drive assembly 120 and the cutter head assembly 140, eliminates the need for a traditional motor, making the overall structure more compact, smaller, and lighter. Furthermore, when the drive assembly 120 is not operating, it does not generate magnetism, facilitating separation of the body and the cutter head holder 130. The drive assembly 120 also does not generate magnetic force on the cutter head assembly 140, facilitating removal of the cutter head holder 130 from the drive base 110.

[0102] The cutter head assembly 140 and the drive assembly 120 are non-contact transmission, and there is no wear, noise or energy loss caused by physical contact, thereby extending the service life.

[0103] It should be noted that the driving base 110 is roughly in the shape of a triangular pyramid, and may be in other shapes in other embodiments, including but not limited to the above-mentioned shapes.

[0104] The discharge hole 130b is a substantially rectangular through hole.

[0105] The sealed cavity 110 a is the inner space of the driving base 110 .

[0106] The shape of the tool head seat 130 is substantially the same as that of the driving base 110 , and the accommodating cavity 130 a is a semi-sealed cavity.

[0107] Preferably, the self-cleaning magnetic levitation shaver 100 further includes:

[0108] A partition plate 160 is installed in the accommodating chamber 130a and divides the accommodating chamber 130a into a negative pressure chamber 160a and a clean chamber 160b. The partition plate 160 has a communication hole 160c, through which the negative pressure chamber 160a communicates with the clean chamber 160b, and the negative pressure chamber 160a communicates with the discharge hole 130b.

[0109] One end of the cutter head assembly 140 is installed in the negative pressure chamber 160a, and the other end passes through the partition plate 160 and extends into the cleaning chamber 160b;

[0110] The negative pressure generating member 150 is located in the negative pressure chamber 160a and is disposed around the cutter head assembly 140;

[0111] The negative pressure generating member 150 rotates to generate negative pressure in the negative pressure chamber 160a, thereby driving the cleaning fluid in the cleaning chamber 160b to generate vortexes, so as to clean the cutter head assembly 140 in the cleaning chamber 160b.

[0112] Please refer to Figures 1-9 In this embodiment, when the cutter head assembly 140 rotates, it drives the negative pressure generating element 150 to rotate synchronously, forming a low-pressure area. This negative pressure is transmitted to the cleaning chamber 160b through the connecting hole 160c, sucking external water or cleaning liquid into the cleaning chamber 160b.

[0113] The sucked cleaning liquid flows in the cleaning chamber 160 b , and due to the negative pressure of the communicating hole 160 c and the rotation direction of the negative pressure generating member 150 , the liquid forms a vortex in the chamber.

[0114] The eddy current moves along the cutter head assembly 140, effectively cleaning its surface and gaps.

[0115] After cleaning, the liquid is guided into the negative pressure chamber 160a and finally discharged from the body through the discharge hole 130b connected to the negative pressure chamber 160a, completing the entire cleaning closed loop.

[0116] It should be noted that a partition plate 160 is provided inside the cutter head seat 130 to separate the accommodating chamber 130a into two closed chambers 143a. The negative pressure chamber 160a is used to generate and maintain negative pressure suction, and the cleaning chamber 160b is used to accommodate the cutter head assembly 140 and realize the cleaning process.

[0117] The partition plate 160 is generally plate-shaped, and in this embodiment is generally triangular, but may have other shapes in other embodiments. A communication hole 160c is provided on the partition plate 160 to form a controlled flow path between the negative pressure chamber 160a and the clean chamber 160b. The communication hole 160c is a through hole.

[0118] The negative pressure generating member 150 is an impeller, which is arranged in the negative pressure chamber 160a and surrounds the outside of the cutter head assembly 140. The negative pressure generating member 150 includes a ring portion and a blade portion arranged on the ring portion. The ring portion is used to be sleeved on the peripheral wall of the cutter head assembly 140.

[0119] The accommodating chamber 130a is rationally divided into sections, the negative pressure chamber 160a is used to generate negative pressure, and the cleaning chamber 160b is focused on cleaning the cutter head area to avoid interference and improve efficiency.

[0120] The liquid flows in a concentrated manner in the cleaning chamber 160b, resulting in high hydraulic utilization and more complete flushing.

[0121] Directional flow guidance is achieved through the communicating hole 160c, so that the cleaning liquid forms a stable vortex in the cleaning chamber 160b.

[0122] The eddy current can generate a stronger impact force on the surface and gaps of the cutter head assembly 140, thereby improving the thoroughness of cleaning and effectively removing impurities such as residual hair and sebum.

[0123] The negative pressure chamber 160a is isolated from the driving assembly 120, thereby improving the sealing and reliability of the overall structure and extending the product life.

[0124] The waste liquid is guided from the cleaning chamber 160b to the discharge hole 130b through the negative pressure chamber 160a, avoiding stagnation in the cleaning chamber 160b, thereby preventing bacteria from growing and odor from accumulating.

[0125] It should be noted that in the process of the drive assembly 120 driving the cutter head assembly 140 to move, the cutter head assembly 140 and the negative pressure generating component 150 form a water pump structure. When liquid enters the accommodating chamber 130a and contacts the negative pressure generating component 150, the negative pressure generating component 150 acts as a water pump to generate negative pressure. Under the joint action of the negative pressure generating component 150 and the cutter head assembly 140, the liquid in the cleaning chamber 160b presents a vortex shape, thereby flushing the surface and gaps of the cutter head assembly 140.

[0126] Preferably, the self-cleaning magnetic levitation shaver 100 further includes:

[0127] The annular member 170 is located in the negative pressure chamber 160a. The annular member 170, the partition plate 160 and the bottom wall of the accommodating chamber 130a form a negative pressure generating chamber 170a and a drainage channel 170b. The annular member 170 is provided with a through hole 170c. The negative pressure generating chamber 170a is connected to the discharge hole 130b through the through hole 170c and the drainage channel 170b.

[0128] Please refer to Figures 1-9In this embodiment, the annular member 170 partially and independently seals the negative pressure chamber 160a to form a negative pressure generating chamber 170a, concentrating the water flow of the negative pressure generating member 150 in the negative pressure generating chamber 170a, thereby improving the concentration and stability of the negative pressure suction force of the water flow.

[0129] The annular member 170 is provided with a through hole 170c, and the negative pressure generating chamber 170a can be connected to the drainage channel 170b through the through hole 170c. The suction force generated by the negative pressure can attract the cleaning liquid through these paths and guide the dirty liquid to be discharged.

[0130] Under the action of negative pressure, the cleaned liquid enters the cleaning chamber 160b through the outside, and under the action of the negative pressure generating element 150, enters the negative pressure chamber 160a, flows through the negative pressure generating chamber 170a, the through hole 170c, the drainage channel 170b, and the discharge hole 130b to the outside.

[0131] The negative pressure generating chamber 170a is formed by the annular member 170, and the negative pressure is concentrated in the designated space, thereby improving the negative pressure forming speed and suction strength during the cleaning process.

[0132] The annular member 170 , the partition plate 160 and the bottom wall of the accommodating cavity 130 a form a clear diversion structure to prevent the cleaning liquid from flowing disorderly or stagnating in the cavity.

[0133] The dirty liquid is effectively guided to quickly enter the drainage channel 170b, reducing residue and secondary pollution, and improving operation stability and cleaning efficiency.

[0134] The annular member 170 serves as a structural isolation component to restrict the flow path of the cleaning liquid, thereby preventing the cleaning liquid from flowing back into the cleaning chamber 160 b and ensuring that the cutter head assembly 140 is not contaminated again.

[0135] Preferably, the cutter head assembly 140 includes:

[0136] The first magnetic yoke 141 is installed in the negative pressure generating chamber 170a, and the negative pressure generating element 150 is installed around the outer circumference of the first magnetic yoke 141;

[0137] a magnetic member 142 , mounted on a side of the first yoke 141 close to the driving assembly 120 and coupled to the driving assembly 120 ;

[0138] The magnetically permeable member 143 is located on a side of the magnetic member 142 close to the driving assembly 120 and is formed with the first magnetic yoke 141 to form a sealed cavity 143 a . The magnetic member 142 is located in the sealed cavity 143 a .

[0139] Please refer to Figures 1-9In this embodiment, the negative pressure generating member 150 is installed around the outer peripheral surface of the first magnetic yoke 141. When the first magnetic yoke 141 rotates with the magnetic force, it also drives the negative pressure generating member 150 to rotate synchronously. During cleaning, the cleaning liquid flows through the negative pressure generating member 150 to form a water pump structure, so that the cleaning liquid inside the cleaning chamber 160b forms a vortex to clean the cutter head assembly 140.

[0140] When the driving assembly 120 is in operation, an alternating magnetic field is generated in the vicinity thereof. The magnetic field penetrates the magnetic permeable member 143 and couples to the magnetic member 142, driving the entire first magnetic yoke 141 to rotate.

[0141] The magnetically permeable member 143 is disposed between the magnetic member 142 and the driving assembly 120 and together with the first magnetic yoke 141 forms a sealed cavity 143a, which seals and protects the magnetic member 142 from water vapor intrusion, thereby achieving complete isolation between the driving area and the cleaning area.

[0142] The drive is achieved through magnetic field coupling between the magnetic member 142 and the drive assembly 120 without mechanical contact or gear meshing.

[0143] The magnetic member 142 is completely enclosed in the sealed cavity 143 a formed by the first magnetic yoke 141 and the magnetically permeable member 143 , preventing the cleaning liquid from entering the electromagnetic induction area.

[0144] The first magnetic yoke 141 , the magnetic member 142 and the magnetically permeable member 143 form an efficient magnetic circuit, which improves energy utilization, reduces energy consumption, and makes the structure more compact and reasonable.

[0145] The negative pressure generating element 150 is mounted around the first magnetic yoke 141 to obtain stable and uniform rotational power. During cleaning, the negative pressure suction is ensured to be continuous and stable, thereby improving the suction efficiency and flushing effect of the blade cleaning liquid.

[0146] When the driving assembly 120 is working, the internal induction coil 122 generates an alternating magnetic field, a portion of which directly passes through the magnetic permeable member 143 and acts on the magnetic member 142 from the driving assembly 120 to drive the magnetic member 142 to move.

[0147] Another part of the magnetic field is reflected by the first magnetic yoke 141 and acts on the magnetic part 142. The two magnetic fields are superimposed on the magnetic part 142 to form a stronger magnetic response torque, thereby improving the response sensitivity of the magnetic part 142 and achieving faster and stronger rotation drive.

[0148] More efficient magnetic flux utilization reduces power waste due to magnetic leakage loss, helping to reduce drive power consumption and improve energy utilization.

[0149] Since the combination of the first magnetic yoke 141 and the magnetic member 142 constitutes a high-efficiency magnetic drive system, the entire negative pressure rotation system is ensured to run smoothly, with low noise and low vibration, which is conducive to the continuous and stable cleaning liquid suction process.

[0150] The magnetic member 142 is located on the side of the first magnetic yoke 141 close to the driving assembly 120. The magnetic member 142 is a ring magnet. In other embodiments, it can be a rectangular magnet arranged in an array or a ring, including but not limited to the above-mentioned arrangement and shape, and a multi-stage magnet can also be used.

[0151] The first magnetic yoke 141 is made of a high magnetic permeability material, such as silicon steel or soft magnetic alloy, for forming a closed magnetic circuit to improve magnetic flux utilization. The first magnetic yoke 141 is located on the side of the magnetic component 142 away from the driving assembly 120; the magnetic permeable component 143 is roughly disc-shaped.

[0152] Preferably, the cutter head assembly 140 further includes:

[0153] The driving shaft 144 has one end rotatably connected to the cutter head holder 130 and is located in the negative pressure generating chamber 170a, and the other end sequentially passes through the magnetically permeable member 143, the sealed chamber 143a, the partition plate 160, and extends into the cleaning chamber 160b;

[0154] The driving gear 145 is mounted on the driving shaft 144 and is located in the cleaning chamber 160b;

[0155] The connecting gear set 146 is installed in the cleaning chamber 160b and meshes with the driving gear 145;

[0156] The cutting unit 147 is installed in the cleaning chamber 160 b and is rotatably connected to the connecting gear set 146 .

[0157] Please refer to Figures 1-9 In this embodiment, one end of the driving shaft 144 is disposed in the negative pressure generating chamber 170 a and is fixedly connected to the first magnetic yoke 141 to receive the rotational force transmitted by the driving assembly 120 .

[0158] The other end of the driving shaft 144 passes through the magnetically permeable member 143 , the sealed cavity 143 a , and the partition plate 160 in sequence, and finally enters the cleaning cavity 160 b , transmitting the rotational force to the connecting gear set 146 .

[0159] The driving shaft 144 is provided with a driving gear 145 at the end of the cleaning chamber 160 b , and the rotation of the driving gear 145 drives the connecting gear set 146 in the cleaning chamber 160 b .

[0160] The connecting gear set 146 can be arranged in parallel or eccentrically, depending on the structure of the cutter head, to achieve rotation direction adjustment or multi-cutter head linkage.

[0161] The cutting unit 147 is connected to the connecting gear set 146, and the rotation of the connecting gear set 146 drives the cutting unit 147 to rotate, thereby completing the shaving action.

[0162] Through the transmission system of the active shaft 144, the driving gear 145 and the connecting gear set 146, accurate and efficient transmission from magnetic coupling to cutter head cutting is achieved, thereby improving the energy conversion efficiency of the system.

[0163] The driving shaft 144 passes through the magnetically permeable component 143, the sealed cavity 143a and the partition plate 160 to achieve power transmission. While ensuring power transmission, it also takes into account sealing and waterproof properties to meet water washing requirements.

[0164] The connecting gear set 146 can be designed as multiple output gears as needed to support multiple cutting units 147 to work together (such as a three-head layout) to improve shaving coverage and efficiency.

[0165] The driving shaft 144 is substantially in the shape of a circular shaft, and the driving gear 145 is a spur gear, a helical gear, or other gears. In this embodiment, a spur gear is used.

[0166] Preferably, the cutter head assembly 140 further includes:

[0167] The mounting frame 148 is fixed in the cleaning chamber 160 b , and the driving shaft 144 and the connecting gear set 146 are both rotatably connected to the mounting frame 148 .

[0168] Please refer to Figures 1-9 In this embodiment, the mounting frame 148 is fixedly installed inside the cleaning chamber 160b, and the driving shaft 144 is stably supported and rotated by setting a rotating bearing position on the mounting frame 148, thereby ensuring its smooth rotation and accurate coaxiality.

[0169] The connecting gear set 146 is mounted on the shaft seat or fulcrum of the mounting frame 148, and through rotational cooperation, the precise transmission and distribution of the cutter head power is achieved.

[0170] The mounting frame 148 serves as a unified supporting structure for the driving shaft 144 and the connecting gear set 146 to prevent problems such as poor gear meshing and shaft offset caused by looseness or deformation.

[0171] Preferably, the driving assembly 120 includes:

[0172] The mounting shell 121 is located in the sealed cavity 110a, and the mounting shell 121 defines a receiving cavity 121a;

[0173] The induction coil 122 is installed in the receiving cavity 121 a and coupled with the magnetic member 142 .

[0174] Please refer to Figures 1-9 In this embodiment, the mounting housing 121 serves as the outer shell of the drive assembly 120 and defines a receiving cavity 121a therein for accommodating the induction coil 122. The induction coil 122 is fixedly mounted within the receiving cavity 121a within the mounting housing 121. When energized, the induction coil 122 generates an alternating magnetic field that passes through the mounting housing 121 and the cutter head holder 130, acting on the magnetic member 142 within the cutter head assembly 140.

[0175] A non-contact magnetic field coupling relationship is formed between the induction coil 122 and the magnetic component 142 , so that the magnetic component 142 generates torque or is subjected to force in the magnetic field.

[0176] The first magnetic yoke 141 , the driving shaft 144 and other components are driven to rotate by the magnetic member 142 , and are finally transmitted to the cutting unit 147 to achieve movement and cleaning of the cutter head.

[0177] Traditional shavers are mostly driven directly by motors, which poses a risk of water ingress. In the self-cleaning magnetic levitation shaver 100, the induction coil 122 and the magnetic part 142 are completely physically isolated, and the cutter head is driven by magnetic coupling.

[0178] The induction coil 122 is located in a completely sealed mounting shell 121, which greatly improves the waterproof level of the shaver and allows the entire body to be washed with water without worrying about electrical short circuits.

[0179] The receiving cavity 121a of the mounting shell 121 securely mounts and electromagnetically shields the induction coil 122 to prevent magnetic flux leakage or external interference. The mounting shell 121 is opened on one side close to the magnetic component 142 to facilitate coupling of the magnetic field of the induction coil 122 with the magnetic component 142, ensuring that the magnetic field is effectively propagated within a specific path, thereby improving the magnetic coupling efficiency and the stability of the power output.

[0180] The induction coil 122 is generally a magnetic induction coil 122 , and there are multiple magnetic induction coils 122 . The multiple magnetic induction coils 122 are disposed in equal angles in the receiving cavity 121 a , and the multiple magnetic induction coils 122 are disposed at equal angles around the axis of the magnetic member 142 .

[0181] Preferably, the driving base 110 has a first magnetically permeable surface 111 on a side close to the tool head seat 130 ;

[0182] The tool head seat 130 has a second magnetically permeable surface 131 on one side close to the driving base 110 ;

[0183] The magnetic field of the induction coil 122 penetrates the first magnetically permeable surface 111 , the second magnetically permeable surface 131 , the magnetically permeable member 143 , and couples with the magnetic member 142 .

[0184] Please refer to Figures 1-9In this embodiment, the first magnetically permeable surface 111 is disposed on a side of the driving base 110 close to the tool head seat 130 , and the magnetic field can penetrate the first magnetically permeable surface 111 to the outside of the driving base 110 .

[0185] The second magnetically permeable surface 131 is disposed on a side of the tool head seat 130 close to the driving base 110 , and the magnetic field can penetrate the second magnetically permeable surface 131 and enter the tool head seat 130 .

[0186] When the induction coil 122 is energized, the magnetic field sequentially passes through the first magnetically permeable surface 111 , the second magnetically permeable surface 131 , and the magnetically permeable member 143 , and finally acts on the magnetic member 142 , forming effective magnetic field coupling at the magnetic member 142 to drive the cutter head to rotate.

[0187] The magnetic member 142 generates electromagnetic force under the action of a changing magnetic field, driving the first magnetic yoke 141 , the driving shaft 144 and other structures connected thereto to rotate.

[0188] The power is transmitted to the cutter head to realize the shaving and cleaning drive functions.

[0189] By setting up a continuous magnetic permeable path (from the first magnetic permeable surface 111 to the second magnetic permeable surface 131 to the magnetic permeable component 143), the magnetic field can be transmitted to the magnetic component 142 with low loss, ensuring the magnetic force output efficiency, reducing the loss and interference of the magnetic field at the structural interface, and improving the drive response speed and torque strength.

[0190] There is no electrical or mechanical connection between the induction coil 122 and the magnetic member 142 , and coupling is achieved entirely through magnetic field penetration, thus preventing water vapor from intruding.

[0191] Preferably, the driving assembly 120 further includes:

[0192] The second magnetic yoke 123 is installed in the receiving cavity 121 a and is located on a side of the induction coil 122 away from the tool head assembly 140 .

[0193] Please refer to Figures 1-9 In this embodiment, after the induction coil 122 is energized, an alternating magnetic field is generated around it. A portion of the magnetic field passes through the magnetic permeable path (through the first magnetic permeable surface 111, the second magnetic permeable surface 131, and the magnetic permeable member 143) in the positive direction and acts on the magnetic member 142, thereby driving the cutting unit 147. Another portion of the magnetic flux will diffuse and reflect toward the back side of the induction coil 122, forming a magnetic field superposition. The magnetic flux is circulated to form a superposition effect with the positive magnetic field, thereby enhancing the positive magnetic flux density.

[0194] The second magnetic yoke 123 allows the magnetic field generated by the induction coil 122 to act more concentratedly on the magnetic member 142, thereby preventing the spread of ineffective magnetic flux, improving the drive response sensitivity and rotation torque of the cutter head assembly 140, reducing energy consumption, and enhancing power transmission.

[0195] The effective magnetic flux returns through the second magnetic yoke 123 to form a complete magnetic circuit, while reducing the interference of the magnetic field on surrounding metal parts or circuits and improving electromagnetic compatibility.

[0196] Secondly, when the induction coil 122 is not working, the magnetic member 142 has a magnetic attraction on the second magnetic yoke 123, so that the tool head holder 130 can be attracted and thus installed on the driving base 110. During disassembly, since the magnetic force of the magnetic member 142 on the second magnetic yoke 123 is relatively small, the tool head holder 130 can be more easily removed from the driving base 110.

[0197] The second magnetic yoke 123 is made of a high magnetic permeability material, for example, silicon steel material or soft magnetic alloy material, and is used to form a closed magnetic circuit to improve the utilization rate of the magnetic flux. The second magnetic yoke 123 is roughly in the shape of a circular plate, and the second magnetic yoke 123 is arranged on the back side of the induction coil 122 in the accommodating cavity 121a, that is, the side of the induction coil 122 away from the cutter head assembly 140. Its function is to guide, reflect or close the loop of the magnetic flux.

[0198] Preferably, the driving assembly 120 further includes:

[0199] The circuit board 180 is disposed in the sealed cavity 110a;

[0200] The power supply 125 is disposed in the sealed cavity 110 a , and the circuit board 180 is electrically connected to the induction coil 122 and the power supply 125 , respectively.

[0201] Please refer to Figures 1-9 In this embodiment, the circuit board 180 is disposed in the sealed cavity 110a of the driving assembly 120 and is completely isolated from the external environment (especially water vapor), ensuring stable operation of its electronic components.

[0202] The circuit board 180 is connected to the power supply 125 , receives stable power from the power supply 125 , and controls the working state of the induction coil 122 .

[0203] The circuit board 180 drives the induction coil 122 to generate an alternating magnetic field by controlling the frequency, waveform, and intensity of the output current.

[0204] The magnetic field acts on the magnetic component 142 in the cutter head assembly 140 through the multi-layer magnetic permeable path, thereby realizing contactless rotation drive of the cutting unit 147.

[0205] The induction coil 122, the circuit board 180, and the power supply 125 are integrated into the sealed cavity 110a, thereby realizing a complete closed-loop electromagnetic drive system.

[0206] The above are only preferred embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's description and drawings, or directly or indirectly applied to other related technical fields, are also included in the patent protection scope of the present invention.
