Description

Technical Field

[0001] This utility model relates to the technical field of shavers, specifically to a magnetic levitation shaver. Background Technology

[0002] The primary purpose of a razor is to remove facial or body hair, leaving the skin smoother and cleaner. Traditional razors are prone to causing cuts or nicks during shaving and take a very long time, while electric razors are convenient to operate and require less time, making them popular among users.

[0003] Traditional electric shavers use a motor that connects directly to the shaver head via gears or a shaft, causing the shaver head to rotate and shave. Because the shaver head is fixedly connected to the motor, the shaver head has a small floating angle, making it difficult to closely follow the skin.

[0004] Therefore, a Chinese patent disclosed a magnetic drive shaver with patent number CN209394710U, which uses a floating shaft to connect the shaver head seat to the housing, so that the shaver head can float and be supported on the housing, allowing the shaver head to swing 360 degrees on the housing, making it easier to fit the skin.

[0005] This magnetic drive shaver uses a power source, magnetic drive components, and magnetic elements connected together to drive the active and driven magnetic rings, thereby enabling the power source to drive the shaver head holder to rotate, which in turn drives the cutting unit to rotate. When removing the shaver head from the body, both the active and driven magnetic rings attract the magnetic elements, making it difficult to remove the shaver head from the body for cleaning and inconvenient to use.

[0006] Secondly, the use of multiple sets of magnetic components for connection makes the overall structure very thick and heavy, making it impossible to be lightweight. It takes up a lot of space when traveling, making it inconvenient to carry. Utility Model Content

[0023] Preferably, the magnetic levitation shaver further includes:

[0024] The circuit board is electrically connected to the drive coil.

[0025] Preferably, the driving magnetic component further includes:

[0026] The connecting shaft has one end inserted through the first magnetic yoke, the magnetic permeable element and the cutter head seat in a rotatable connection, and the other end rotatably connected to the cutting assembly.

[0027] Preferably, the magnetic levitation shaver further includes:

[0035] Preferably, the magnetic levitation shaver further includes:

[0036] Mounting bracket, the connecting gear is rotatably connected to the mounting bracket, and the mounting bracket is fixed inside the motion cavity.

[0037] Preferably, the magnetic levitation shaver further includes:

[0038] A negative pressure generating component is arranged around the outer peripheral surface of the first magnetic yoke and is fixedly connected to the first magnetic yoke. The cutter head seat has a cleaning hole, which communicates with the motion cavity.

[0039] Preferably, the magnetic levitation shaver further includes:

[0040] The power supply is fixed inside the accommodating cavity and electrically connected to the circuit board.

[0041] A switch is located on the body of the device and is electrically connected to the circuit board;

[0042] The charging port is installed on the device body and electrically connected to the circuit board.

[0043] The magnetic levitation shaver proposed in this invention has the following beneficial effects:

[0044] 1. The magnetic levitation shaver proposed in this utility model, when activated, has its drive coil energized, generating a magnetic field. The driving magnetic component is located within the magnetic field area of ​​the drive coil. The alternating magnetic field generated by the drive coil electromagnetically couples with the magnetic unit in the driving magnetic component. Under the influence of the changing magnetic field, the driving magnetic component rotates, driving the cutting component to move, thereby cutting beards or hair. When the shaver is off, the drive coil is no longer energized, the magnetic field disappears, and the driving magnetic component is no longer attracted. The entire drive structure consists of the drive coil and the magnetic component, eliminating the need for a traditional motor, making the overall structure more compact, smaller, and lighter. Furthermore, when the drive coil is not operating, it does not generate magnetism, facilitating the separation of the shaver body and the shaver head holder. The drive coil does not exert magnetic force on the driving magnetic component, allowing the shaver head holder to be easily removed from the shaver body.

[0045] 2. The magnetic levitation shaver proposed in this utility model has an energized drive coil that generates an alternating magnetic field. The magnetic field is conducted to the magnetic unit through the first and second magnetic surfaces and the magnetic component between the body and the shaver head. The magnetic unit is coupled with the magnetic field of the drive coil and rotates under the action of the magnetic field. The first magnetic yoke and the magnetic component cooperate to form a closed and focused magnetic circuit, which guides the magnetic flux to be evenly distributed around the magnetic unit, reducing magnetic leakage. The transmission structure drives the cutting component of the shaver head to move, thereby realizing the shaving function.

[0046] Secondly, since the first magnetic yoke is located on the side of the magnetic unit away from the drive coil, the magnetic field generated by the drive coil is reflected by the first magnetic yoke and then applied to the magnetic unit, forming an enhanced magnetic coupling effect, which greatly improves the magnetic energy output per unit input power and improves the overall energy efficiency.

[0047] Because the magnetic unit is subjected to a composite magnetic field from both the front and the back, its driving torque and response speed are significantly improved, thus enhancing shaving efficiency and smoothness.

[0048] 3. The magnetic levitation shaver proposed in this utility model, when the drive coil is not energized, uses a second magnetic yoke made of a magnetically attractable material. This allows the magnetic unit to exert a certain magnetic force on the second magnetic yoke, thereby attracting the shaver head holder to be installed onto the body. During disassembly, because the magnetic force exerted by the magnetic unit on the second magnetic yoke is very small, the shaver head holder can be removed from the body more easily.

[0069] 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

[0070] 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.

[0071] 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.

[0072] This utility model provides a magnetic levitation shaver 100, comprising:

[0073] The fuselage 110 has an internal cavity 110a;

[0074] A drive coil 120 is disposed within the accommodating cavity 110a;

[0075] The cutter head holder 130 has a moving cavity 130a formed inside;

[0076] The cutting assembly 140 is disposed within the motion cavity 130a;

[0077] A driving magnetic component 150 is located within the motion cavity 130a and is connected to the cutting component 140 in a transmission manner.

[0078] When the drive coil 120 is energized, the drive coil 120 is coupled to the drive magnetic component 150 to drive the cutting component 140 to shave.

[0079] Please refer to Figures 1-8 In this embodiment, after the magnetic levitation shaver 100 is started, the drive coil 120 is energized and the drive coil 120 begins to generate a magnetic field.

[0080] The driving magnetic component 150 is located in the magnetic field area of ​​the driving coil 120. The alternating magnetic field generated by the driving coil 120 is electromagnetically coupled with the magnetic unit 151 in the driving magnetic component 150. Under the action of the magnetic field change, the driving magnetic component 150 rotates, and the driving magnetic component 150 drives the cutting component 140 to move, thereby realizing the cutting of beards or hair.

[0081] When the shaver is off, the drive coil 120 is no longer energized, the magnetic field disappears, and the drive magnetic component 150 is no longer attracted. At this time, there is no magnetic attraction between the shaver head holder 130 and the body 110, allowing the user to easily remove the shaver head holder 130 for cleaning or replacement.

[0082] The entire drive structure consists of a drive coil 120 and a magnetic component, eliminating the need for a traditional motor, resulting in a more compact structure and a smaller, lighter overall machine. Furthermore, when the drive coil 120 is not in operation, it does not generate magnetism, facilitating the separation of the machine body 110 and the cutter head holder 130. The drive coil 120 also does not exert magnetic force on the drive magnetic component 150, allowing the cutter head holder 130 to be removed from the machine body 110.

[0083] The drive coil 120 and the magnetic components are connected by non-contact transmission, eliminating wear, noise, or energy loss caused by physical contact and extending service life.

[0084] It should be noted that the fuselage 110 is generally in the shape of a truncated triangular prism, but in other embodiments it can be in other shapes, including but not limited to the shape described above. The accommodating cavity 110a is a hollow structure inside the fuselage 110.

[0085] The drive coil 120 is a magnetic induction coil.

[0086] Preferably, the body 110 has a first magnetically permeable surface 110b on the side near the cutter head holder 130, and the cutter head holder 130 has a second magnetically permeable surface 130b on the side near the cutter head holder 130. The magnetic field of the drive coil 120 passes through the first magnetically permeable surface 110b and the second magnetically permeable surface 130b and couples with the drive magnetic component 150.

[0087] Please refer to Figures 1-8 In this embodiment, the first magnetically permeable surface 110b is located on the side of the body 110 near the cutter head seat 130, and the second magnetically permeable surface 130b is located on the side of the cutter head seat 130 near the body 110. After the drive coil 120 is energized, an alternating magnetic field is formed in the accommodating cavity 110a. This magnetic field is conducted along the path from the drive coil 120, the first magnetically permeable surface 110b, the second magnetically permeable surface 130b to the drive magnetic component 150. Through the first magnetically permeable surface 110b and the second magnetically permeable surface 130b, the magnetic flux can efficiently penetrate the body 110 and enter the cutter head seat 130, and effectively couple with the drive magnetic component 150 to drive the drive magnetic component 150 to rotate, thereby driving the cutting component 140 to cut the hair.

[0088] By setting up a first magnetic permeable surface 110b and a second magnetic permeable surface 130b, the magnetic resistance between the body 110 and the shaving head holder 130 is significantly reduced, making it easier for the magnetic field to penetrate the boundary of the structure, thereby improving the magnetic energy transfer efficiency, enhancing the response speed and rotational torque of the drive magnetic component 150, and achieving fast and stable shaving head start and shaving.

[0089] Using permeable magnetic materials to form a smooth magnetic flux path can effectively control the direction and range of the magnetic field and reduce the interference of magnetic field leakage to other circuits or equipment.

[0090] Preferably, the driving magnetic component 150 includes:

[0091] Magnetic unit 151 is coupled to the magnetic field of the drive coil 120;

[0092] The first magnetic yoke 152 is located on the side of the magnetic unit 151 away from the drive coil 120;

[0093] The magnetically permeable element 153 forms a sealed cavity with the first magnetic yoke 152, and the magnetic unit 151 is installed in the sealed cavity.

[0094] Please refer to Figures 1-8 In this embodiment, the drive coil 120 is energized to generate an alternating magnetic field. The magnetic field is conducted to the magnetic unit 151 through the first magnetically permeable surface 110b, the second magnetically permeable surface 130b, and the magnetically permeable element 153 between the body 110 and the head holder 130. The magnetic unit 151 is coupled with the magnetic field of the drive coil 120 and rotates under the action of the magnetic field. The first magnetic yoke 152 and the magnetically permeable element 153 cooperate to form a closed and focused magnetic circuit, guiding the magnetic flux to be evenly distributed around the magnetic unit 151, reducing magnetic leakage. The transmission structure drives the cutting component 140 of the shaver head to move, realizing the shaving function.

[0095] Secondly, since the first magnetic yoke 152 is located on the side of the magnetic unit 151 away from the drive coil 120, the magnetic field generated by the drive coil 120 is reflected by the first magnetic yoke 152 and further applied to the magnetic unit 151, forming an enhanced magnetic coupling effect, which greatly improves the magnetic energy output per unit input power and improves the overall energy efficiency.

[0096] Because the magnetic unit 151 is subjected to a composite magnetic field from both the front and rear, its driving torque and response speed are significantly enhanced, improving shaving efficiency and smoothness.

[0097] By forming a closed magnetic circuit with the first magnetic yoke 152 and the magnetic permeable element 153, magnetic flux leakage is greatly reduced, the magnetic field is concentrated on the magnetic unit 151, the magnetic energy driving efficiency is improved, and the cutting assembly 140 is more responsive and operates more stably.

[0098] The magnetic unit 151 is placed in a sealed cavity surrounded by the first magnetic yoke 152 and the magnetic permeable element 153, which effectively prevents dust, hair or moisture from entering the area of ​​the driving magnetic component 150 and avoids affecting the magnetic unit 151.

[0099] It should be noted that the magnetic unit 151 is a ring magnet. In other embodiments, it can be a rectangular magnet arranged in an array or ring, including but not limited to the above-mentioned arrangement and shape, and multi-stage magnets can also be used. The first magnetic yoke 152 is made of a high-permeability material to form a closed magnetic circuit to improve magnetic flux utilization. For example, it is made of silicon steel or soft magnetic alloy. The first magnetic yoke 152 is located on the side of the magnetic unit 151 away from the drive coil 120. The magnetically permeable part 153 is generally disk-shaped.

[0100] A sealed cavity is formed between the magnetically permeable element 153 and the first magnetic yoke 152, and the magnetic unit 151 is installed in this cavity. The magnetically permeable element 153 is a material that allows magnetic flux to pass through, while also providing protection and directional magnetic guidance.

[0101] Preferably, the thickness of the driving magnetic component is denoted as a, and satisfies the relationship: 1≤a≤5mm.

[0102] In this embodiment, since the overall thickness of the driving magnetic component is in the range of 1mm to 5mm, the thickness of the driving magnetic component is thinner, the overall thickness of the shaver head is thinner, and thus the overall thickness of the magnetic levitation shaver 100 is thinner, making it easier to carry around and reducing the space occupied by the magnetic levitation shaver 100 during the process of carrying it around.

[0103] Preferably, the magnetic levitation shaver 100 further includes:

[0104] The mounting plate 160 has an internal mounting cavity 160a, and multiple sets of the drive coils 120 are arranged around the mounting cavity 160a.

[0105] Please refer to Figures 1-8 In this embodiment, multiple coils are arranged in a ring, resulting in a more symmetrical and balanced magnetic field distribution. The magnetic unit 151 is not subject to unidirectional offset force, making the movement of the shaving head more stable and effectively avoiding problems such as jumping, jamming, or uneven vibration. This makes shaving smoother and more comfortable, and drives the cutting component 140 inside the shaving head to achieve synchronous, stable, and efficient rotary shaving action.

[0106] Multiple drive coils (120) can superimpose magnetic field effects, increasing the overall magnetic drive strength without increasing the power of a single coil. This makes it particularly suitable for driving multiple blades or high-resistance cutting structures, resulting in a more powerful and efficient shave.

[0107] It should be noted that the mounting plate 160 is generally open on one side and forms a mounting cavity 160a inside, and is a cylindrical shell closed on the other side. The mounting plate 160 has multiple positioning posts inside, which are used to fix multiple sets of drive coils 120.

[0108] Preferably, the magnetic levitation shaver further includes:

[0109] The second magnetic yoke 200 is installed on the side of the drive coil 120 away from the drive magnetic assembly 150.

[0110] In this embodiment, since the second magnetic yoke 200 is located on the side of the drive coil away from the drive magnetic component 150, during the process of the drive coil 120 generating a magnetic field, part of the magnetic field will directly act on the magnetic unit 151, and another part of the magnetic field (i.e. the side closer to the second magnetic yoke 200) will be reflected by the second magnetic yoke 200 to form a superimposed magnetic field that acts on the magnetic unit 151. This results in the two magnetic fields superimposing at the magnetic unit 151, forming a stronger magnetic response torque, improving the response sensitivity of the magnetic unit 151, and achieving faster and stronger rotational drive.

[0111] More efficient flux utilization reduces power waste caused by magnetic leakage losses, which helps to reduce drive power consumption and improve energy efficiency.

[0112] It should be noted that the second magnetic yoke 200 is roughly disk-shaped and made of a high-permeability material to form a closed magnetic circuit, thereby improving magnetic flux utilization, and is made of the same material as the first magnetic yoke 152.

[0113] Secondly, when the drive coil 120 is not energized, the second magnetic yoke 200, being made of a magnetically attractable material, exerts a magnetic force on the magnetic unit 151, thereby attracting the cutter head holder 130 to be mounted onto the machine body 110. During disassembly, because the magnetic force exerted by the magnetic unit 151 on the second magnetic yoke 200 is very weak, the cutter head holder 130 can be removed from the machine body 110 more easily.

[0114] Preferably, the magnetic levitation shaver further includes:

[0115] The negative pressure generating component 210 is arranged around the outer peripheral surface of the first magnetic yoke 152 and is fixedly connected to the first magnetic yoke 152. The cutter head seat 130 has a cleaning hole 130c, which is connected to the motion cavity 130a.

[0116] In this embodiment, during cleaning, cleaning liquid is injected into the motion cavity 130a. Under the action of the magnetic field of the drive coil 120, the magnetic unit 151 is driven to rotate in the motion cavity. Since the negative pressure generating component 210 is installed on the outer peripheral surface of the first magnetic yoke 152, the magnetic unit 151 is fixed between the first magnetic yoke 152 and the magnetic permeable component 153, causing the magnetic unit 151 to rotate. This causes the negative pressure generating component 210 around the magnetic unit 151 to rotate at high speed. The high-speed rotating negative pressure generating component 210 and the interior of the motion cavity 130a form the characteristics of a water pump to generate negative pressure. Finally, external water is drawn into the motion cavity 130a through the negative pressure for cleaning.

[0117] When the cleaning liquid comes into contact with the negative pressure generating element 210, the negative pressure generating element 210 will drive the cleaning liquid to rotate in the motion chamber 130a to form a water pump structure to clean the cutting head 192, and finally discharge it to the outside through the cleaning hole 130c to complete the cleaning process.

[0118] With its magnetic levitation drive and negative pressure water suction structure, the shaver can be cleaned without disassembling it, greatly improving ease of use and daily maintenance efficiency.

[0119] It should be noted that the negative pressure generating component 210 is an impeller.

[0120] Preferably, the magnetic levitation shaver 100 further includes:

[0121] Circuit board 170 is electrically connected to the drive coil 120.

[0122] Please refer to Figures 1-8 In this embodiment, the circuit board 170 is electrically connected to the drive coil 120. The circuit board 170 is used to control the drive coil 120 to be energized or de-energized, thereby controlling the cutting assembly 140 to perform cutting or stop cutting.

[0123] Preferably, the driving magnetic component 150 further includes:

[0124] The connecting shaft 180 has one end inserted through the first magnetic yoke 152, the magnetically permeable element 153 and the cutter head seat 130 and is rotatably connected, and the other end is rotatably connected to the cutting assembly 140.

[0125] Please refer to Figures 1-8 In this embodiment, one end of the connecting shaft 180 passes through the first magnetic yoke 152 and the magnetic permeable element 153, and is rotatably connected to the cutter head holder 130. After the drive coil 120 is energized, the magnetic field acts on the magnetic unit 151, and the magnetic unit 151 rotates relative to the first magnetic yoke 152 and the magnetic permeable element 153, driving the connecting shaft 180 to rotate. The other end of the connecting shaft 180 is rotatably connected to the cutting assembly 140 to transmit rotational torque, ensuring that the cutting head 192 performs continuous and stable rotational motion to complete shaving.

[0126] By using magnetic drive and connecting shaft 180, the vibration and wear problems caused by the rigid connection between the motor and the cutter head in the traditional structure are avoided, thereby reducing operating noise and improving user comfort.

[0127] It should be noted that the connecting shaft 180 is roughly round.

[0128] Preferably, the magnetic levitation shaver 100 further includes:

[0129] The drive gear 181 is mounted on the connecting shaft 180 and is connected to multiple sets of the cutting components 140 in a transmission manner.

[0130] Please refer to Figures 1-8 In this embodiment, when the drive coil 120 is energized, the magnetic field it generates is coupled with the drive magnetic component 150. The drive magnetic component 150 rotates under the action of magnetic force, thereby driving the connecting shaft 180 to rotate, which in turn drives the drive gear 181 on the connecting shaft 180 to rotate synchronously. The drive gear 181 is connected to each cutting component 140 through transmission, realizing the linkage drive of multiple cutting components 140. Multiple cutting components 140 can rotate at the same time to achieve large-area, multi-directional shaving.

[0131] Multiple cutting components 140 can work at the same time, significantly increasing the shaving coverage area and shortening the shaving time. The drive gear 181 can transmit the rotational motion of the connecting shaft 180 to multiple cutting components 140 in a set ratio, ensuring that each cutting component 140 is subjected to balanced force and rotates at the same speed, and avoiding incomplete shaving due to insufficient force on a certain blade.

[0132] The drive gear 181 is a spur gear, but in other embodiments it can be a gear of other shapes, including but not limited to spur gears, helical gears, etc.

[0133] Preferably, the cutting assembly 140 includes:

[0134] A connecting gear 190 is installed in the motion cavity 130a and meshes with the drive gear 181.

[0135] The floating component 191 is engaged at one end with the connecting gear 190;

[0136] The cutting head 192 is installed in the motion cavity 130a and engages with the other end of the floating member 191.

[0137] Please refer to Figures 1-8 In this embodiment, the floating member 191 is disposed between the connecting gear 190 and the cutting head 192, which plays a role in flexible transition, allowing the cutting head to flexibly adjust its angle under different angles and pressures, so as to better fit the curved areas such as the face, chin, and neck.

[0138] The drive gear 181 rotates through the connecting shaft 180, transmitting power to the connecting gear 190 installed in the motion cavity 130a. The connecting gear 190 meshes with the drive gear 181 to achieve synchronous transmission of angular velocity.

[0139] The connecting gear 190 and the floating part 191 are connected by a snap-fit ​​connection, which can achieve power transmission while retaining a certain floating space, allowing the floating part 191 to move up and down or tilt within a certain range to fit the curved surface of the face.

[0140] The other end of the floating member 191 engages with the cutting head 192. The cutting head 192 moves with the floating member 191 and is simultaneously subjected to the rotational power brought by the connecting gear 190, thus achieving synchronous cutting.

[0141] Multiple cutting heads 192 can float independently and be driven synchronously through the same structure, improving efficiency when shaving large areas. The heads can dynamically adapt to the curvature of the face, reducing pulling and irritation to the skin.

[0142] It should be noted that the cutting assembly 140 is an existing structure and will not be described in detail here.

[0143] Preferably, the magnetic levitation shaver 100 further includes:

[0144] Mounting bracket 193, the connecting gear 190 is rotatably connected to the mounting bracket 193, and the mounting bracket 193 is fixed inside the motion cavity 130a.

[0145] Please refer to Figures 1-8 In this embodiment, the mounting bracket 193 is securely installed in the motion cavity 130a formed within the cutter head holder 130 to ensure that it does not shift during operation. The connecting gear 190 is rotatably connected to the mounting bracket 193 via bearings or the like. The mounting bracket 193 precisely positions the connecting gear 190 so that it can rotate smoothly around a fixed axis while maintaining its meshing relationship with the drive gear 181. This ensures both the freedom of gear rotation and the necessary stability.

[0146] The mounting bracket 193 supports and guides the connecting gear 190, ensuring smooth meshing and reducing power transmission loss or abnormal meshing caused by positional deviation. This enhances the mechanical reliability of the cutting assembly 140 during operation and reduces problems such as jamming and tooth skipping.

[0147] Preferably, the magnetic levitation shaver 100 further includes:

[0148] Power supply 194 is fixed inside the accommodating cavity 110a and electrically connected to the circuit board 170;

[0149] Switch 195 is located on the body 110 and is electrically connected to the circuit board 170;

[0150] The charging port 196 is installed on the body 110 and is electrically connected to the circuit board 170.

[0151] Please refer to Figures 1-8 In this embodiment, the power supply 194 is located in the accommodating cavity 110a inside the body 110. The power supply 194 can be a rechargeable lithium battery or other lightweight storage battery. The power supply 194 is connected to the circuit board 170 to provide the working voltage and current required for the operation of the whole machine. The power supply 194 provides continuous and stable power to the drive coil 120, control circuit, etc.

[0152] The switch 195 is located on the outer casing of the body 110 for easy operation by the user, and is located on the side of the body 110 away from the head holder 130. The switch 195 is connected to the circuit board 170 and is used to control the power on / off state of the shaver. After the user presses the switch 195, the circuit board 170 controls the power supply 194 to supply power to the drive coil 120, starting the magnetic levitation drive shaving.

[0153] The charging port 196 is located on the outside of the body 110, which facilitates the charging of the power supply 194 by an external power source (such as USB or adapter).
