Description

Technical Field

[0001] This application relates to the field of small household appliance technology, and in particular to a blade assembly and a shaver. Background Technology

[0002] With the increasing demand for personal care among modern people, razors have become an indispensable personal care tool in daily life.

[0003] However, since the shaving components of razors are usually made of hard materials, and different users have different facial contours, the razor's fit to the face is poor and its adaptability is poor, resulting in a poor user experience and affecting shaving efficiency and results. Summary of the Invention

[0004] The purpose of this application is to provide a blade assembly and a razor having the same.

[0005] To achieve at least one of the above-mentioned objectives, one embodiment of this application provides a cutting head assembly, comprising:

[0006] The base has an axis;

[0007] The razor head holder is equipped with a razor assembly;

[0008] A floating mechanism connects the base and the cutter head holder, allowing the cutter head holder to deflect relative to the axis under the action of an external force, and allowing the cutter head holder to return to its original position after the external force is removed.

[0009] The razor head assembly provided in this application, through a floating mechanism, allows the razor head seat to deflect relative to the axis of the base during shaving, thereby maintaining a good fit between the razor assembly and the user's face, increasing the razor's fit to the face. This allows the razor to adaptively adjust its position according to the user's facial contours; it also helps to tighten the facial skin, allowing the hair roots to be better exposed on the skin surface, improving shaving cleanliness, while also enhancing shaving comfort and experience, reducing pressure on the skin during shaving, and minimizing skin irritation. Furthermore, the razor head seat can return to its initial position after the external force is removed, facilitating the next use.

[0010] As a further improvement of one embodiment of this application, the base has a connecting part, the cutter head seat has a rotating part, and the connecting part and the rotating part are rotatably connected.

[0011] With this configuration, the cutter head holder can rotate relative to the base through the cooperation of the connecting part and the rotating part, so that the cutter head holder can deflect in a specific direction under the action of external force and reset after the external force is removed.

[0012] As a further improvement of one embodiment of this application, the angle range of the blade holder rotating around the connecting portion is 0 to 15°.

[0013] This setting ensures that the head can deflect relative to the axis of the base, allowing for a better fit between the razor assembly and the user's face. It also prevents excessive deflection of the head, ensuring appropriate fit and preventing instability caused by excessive deflection during shaving. This effectively balances the need for deflection flexibility and structural stability of the head, improving comfort and safety during use.

[0014] As a further improvement of one embodiment of this application, the floating mechanism is a torsion structure, the rotation axis of the connecting part and the rotating part passes through the torsion structure, the torsion structure acts on the cutter head seat and the base, and provides a torsion force so that the cutter head seat rotates or resets relative to the base.

[0015] With this configuration, a torsion structure is used as the floating mechanism, and the rotation axes of the connecting part and the rotating part pass through the torsion structure. When the cutter head holder deflects under the action of external force, the torsion structure stores energy. After the external force is removed, the torsion structure releases energy and provides torsional force to reset the cutter head holder. This torsion structure provides uniform damping force for the deflection of the cutter head holder, making the deflection of the cutter head assembly smoother. At the same time, the structure is simple and compact, which can effectively reduce wear and fatigue and improve the service life of the floating mechanism.

[0016] As a further improvement of one embodiment of this application, the floating mechanism is a linear reciprocating structure, one end of which is rotatably connected to the cutter head holder, and the other end of which is rotatably connected to the base. The linear reciprocating structure provides a reciprocating force so that the cutter head holder rotates or resets relative to the base.

[0017] In this configuration, the linear reciprocating structure is connected to the cutter head holder and the base via rotatable connection points at both ends, forming a kinematic chain. When the cutter head holder deflects relative to the base, the linear reciprocating structure provides a reciprocating force to control the deflection motion and achieve a reset function. This structure provides more precise floating control, keeping the cutter head in a suitable contact state. Compared to a torsion structure, it is more stable and provides a more stable reset force, reducing the deflection deviation of the cutter head holder during use.

[0018] As a further improvement of one embodiment of this application, the linear reciprocating structure includes an elastic element, which is disposed between the cutter head seat and the base;

[0019] Under the action of external force, the cutter head holder can overcome the elastic force of the elastic element and deflect closer to the base; after the external force is removed, the elastic force of the elastic element allows the cutter head holder to deflect away from the base and reset.

[0020] This design allows the elastic element to provide reliable elastic restoring force to the razor head, ensuring that the razor returns to its initial position after use. It also simplifies the structure and reduces manufacturing costs. Furthermore, the elastic element ensures that the razor head maintains appropriate pressure at all times, improving shaving performance.

[0021] As a further improvement of one embodiment of this application, the linear reciprocating structure includes a first support member, which is connected to the base or the cutter head holder;

[0022] In the circumferential direction of the elastic element, the first support member covers at least a portion of the elastic element;

[0023] Alternatively, the elastic element may be sleeved on the first support element.

[0024] With this configuration, the first support can guide and protect the elastic element, preventing it from lateral deformation or detachment during operation and ensuring the stability of the axial deflection of the cutter head relative to the base.

[0025] As a further improvement of one embodiment of this application, the linear reciprocating structure further includes a second support member, one of the first support member and the second support member being rotatably connected to the base, and the other being rotatably connected to the cutter head seat, and the elastic member being disposed between the first support member and the second support member;

[0026] Under the action of external force, the second support member compresses the elastic member relative to it; after the external force is removed, the elastic member rebounds and abuts against the second support member.

[0027] This configuration, through the cooperation of the first support member, the second support member, and the elastic member, forms a complete support structure, which can realize the compression and rebound control of the elastic member, improve the responsiveness of the floating mechanism, optimize the force transmission path, and improve the floating efficiency and service life.

[0028] As a further improvement of one embodiment of this application, one of the first support member and the second support member is provided with a sliding groove, and the other is provided with a snap-fit ​​part, wherein the snap-fit ​​part is located in the sliding groove and can slide along the sliding groove.

[0029] This design, with its groove and locking mechanism, allows the two supports to slide relative to each other in a specific direction during the floating process, while restricting movement in unintended directions, thus improving the stability and reliability of the floating mechanism. This design not only simplifies the assembly process and facilitates production and maintenance, but also effectively controls the floating direction and prevents skewing during the deflection of the cutter head.

[0030] As a further improvement of one embodiment of this application, the cutter head seat corresponds one-to-one with the floating mechanism and multiple sets are provided, and they are spaced apart along the circumference of the base.

[0031] With this configuration, each shaving head is connected to the base via an independent floating mechanism, forming multiple independent floating shaving units. This also integrates multiple shaving components, significantly increasing the coverage area of ​​the shaving head assembly and thus improving shaving efficiency. Moreover, this circumferentially distributed design has a compact structure, which expands the shaving area while controlling the size of the shaving head, improving the overall working efficiency of the shaving head assembly. It also balances the vibration during shaving operation, enhancing stability.

[0032] As a further improvement of one embodiment of this application, a limiting member is provided between adjacent cutter head seats, and the limiting member is connected to the base; the limiting member is used to limit the deflection angle of the cutter head seats.

[0033] With this configuration, when the cutter head holder deflects to its maximum deflection angle relative to the axis of the base under the action of external force, the part of the cutter head holder near the limiting member will abut against the limiting member, thereby limiting the excessive deflection of the cutter head holder.

[0034] As a further improvement of one embodiment of this application, the razor assembly includes a rotary razor and a reciprocating razor spaced apart, wherein the relatively longer side of the rotary razor and the relatively longer side of the reciprocating razor intersect the axis when projected onto the axis.

[0035] This design allows the rotary razor to cut short hairs by rotating, while the reciprocating razor can effectively cut long beards and curly hairs by reciprocating. This achieves a combination of reciprocating and rotary shaving functions, enabling efficient handling of hair of different lengths and types and improving the user's shaving experience. It also avoids the situation where the relatively longer side of the rotary or reciprocating razor is parallel to the axis of the base, which would prevent the razor assembly from working effectively.

[0036] As a further improvement of one embodiment of this application, the razor head assembly further includes a rolling element; the razor assembly includes at least two razors, the at least two razors being staggered in the length direction, and the rolling element being disposed between two adjacent razors.

[0037] This design not only improves the smoothness of the razor assembly's movement and enhances shaving comfort, effectively preventing skin damage caused by friction, but also, when the razor head is deflected relative to the base's axis under external force, the rolling element tends to move away from the base's axis, thus tightening the facial skin and exposing the hair roots to the skin surface. This facilitates the rotary razor's trimming of short hairs and improves the cleanliness of the shave.

[0038] As a further improvement of one embodiment of this application, along the length direction of the rolling element, at least a portion of the diameter of the rolling element is larger than the diameter of the other portions.

[0039] This design reduces the contact area between the rollers and the face, further improving the smoothness of the razor assembly's movement and allowing it to better adapt to facial contours, thus enhancing the user experience.

[0040] As a further improvement of one embodiment of this application, the blade assembly further includes a cover housing, the cover housing being disposed on the blade head seat, the end of the cover housing away from the blade head seat having an opening, the blade head seat having a razor assembly disposed on the blade head seat, the razor assembly being partially exposed in the opening, and the surface of the cover housing away from the blade head seat having a smoothing area.

[0041] This design not only allows the razor assembly to contact the face for shaving, but also allows the razor to move more smoothly along the skin, improving user comfort. The cover also protects the head and razor assembly from external objects entering or damaging the razor assembly.

[0042] To achieve at least one of the above-mentioned objectives, one embodiment of this application also provides a razor, including the blade assembly as described above.

[0043] The shaver provided in this application, through a floating mechanism, allows the shaver head to deflect relative to the axis of the base during shaving, thereby maintaining a good fit between the shaver assembly and the user's face, increasing the shaver's fit to the face. This allows the shaver to adaptively adjust its position according to the user's facial contours; it also helps to tighten the facial skin, allowing the hair roots to be better exposed to the skin surface, improving shaving cleanliness, while also enhancing shaving comfort and experience, reducing pressure on the skin during shaving, and minimizing skin irritation. Furthermore, the shaver head can return to its initial position after the external force is removed, facilitating the next use. Attached Figure Description

Detailed Implementation

[0052] The present application will now be described in detail with reference to the specific embodiments shown in the accompanying drawings.

[0053] In the various figures of this application, for ease of illustration, certain dimensions of structures or parts are enlarged relative to other structures or parts; therefore, they are only used to illustrate the basic structure of the subject matter of this application.

[0054] It should be understood that although the terms "first," "second," etc., may be used in this document to describe various elements, structures, or parameters, the objects being described should not be limited by these terms. These terms are only used to distinguish these objects from one another.

[0055] See Figure 1 This embodiment provides a razor 1000, mainly used for shaving beards or hair on the face, neck, and other areas for personal care. Specifically, in this embodiment, the razor 1000 is an electric razor.

[0056] As a trimming tool for beards and hairs, an electric shaver drives the movement of the cutter head through a power source to cut and clean the beards and hairs. Compared with traditional manual shavers, it is not only efficient and safe, but also has a better shaving effect and is more convenient to use.

[0057] See Figures 1 to 2 , the shaver 1000 includes a cutter head assembly, a holding part 200 and a power source 300. The cutter head assembly 100 and the holding part 200 are assembled to form the shaver 1000. The power source 300 is arranged in the holding part 200. The power source 300 can specifically adopt a motor or a battery, and drives the shaving unit in the cutter head assembly 100 to move reciprocally and / or rotate to achieve shaving.

[0058] Refer Figures 2 to 4 As shown, the cutter head assembly 100 includes a base 1, a cutter head seat 2 and a floating mechanism 3.

[0059] The base 1 is used to support the cutter head seat 2, and the base 1 has an axis x; the cutter head seat 2 is provided with a razor assembly 21 for realizing the shaving function; the floating mechanism 3 connects the base 1 and the cutter head seat 2, and allows the cutter head seat 2 to deflect relative to the axis x of the base 1 under the action of an external force, and allows the cutter head seat 2 to reset after the external force is removed.

[0060] Through the floating mechanism 3, the cutter head seat 2 can deflect relative to the axis x of the base 1 during shaving, so that the razor assembly 21 can maintain a good fitting state with the user's face, increasing the fitting degree between the shaver 1000 and the face. In this way, the position can be adaptively adjusted according to the facial contour of the user of the shaver 1000; during the process of the cutter head seat 2 deflecting relative to the axis x of the base 1, the friction between the cutter head seat 2 and the skin can also drive the skin to move, so as to play a role in tightening the facial skin, making the hair roots better exposed on the skin surface, improving the shaving cleanliness, and at the same time enhancing the comfort and experience of shaving, reducing the pressure on the skin during shaving, and reducing skin irritation; and after the external force is removed, the cutter head seat 2 can reset to the initial position for the next use.

[0061] For the convenience of description, in this embodiment, the direction from the holding part 200 towards the cutter head assembly 100 is defined as up, and vice versa as down; then the axis x of the base 1 extends in the up and down direction.

[0062] In this embodiment, the floating mechanism 3 allows the cutter head seat 2 to deflect自上而下 relative to the axis x of the base 1 under the action of an external force, and allows the cutter head seat 2 to reset自下而上 after the external force is removed.

[0063] Refer Figures 1 to 4 As shown, in this embodiment, the cutter head seat 2 and the floating mechanism 3 are provided in multiple groups in one-to-one correspondence and are arranged at intervals along the circumference of the base 1.

[0064] In this way, each cutter head seat 2 is connected to the base 1 through an independent floating mechanism 3, forming multiple independently floating razor units. At the same time, the integrated setting of multiple razor assemblies 21 is realized, greatly increasing the coverage area of the cutter head assembly 100, thereby improving the shaving efficiency. Moreover, this circumferential distribution design has a compact structural layout. While expanding the shaving area, it controls the head size of the razor 1000, improves the overall working efficiency of the cutter head assembly 100, and also balances the vibration during the operation of the razor 1000, enhancing the stability.

[0065] In this embodiment, there are three groups of cutter head seats 2 and floating mechanisms 3 arranged in one-to-one correspondence. The structural layout is compact and the layout is reasonable, controlling the overall size of the cutter head assembly 100 while ensuring the cutting area. Of course, the specific number of cutter head seats 2 and floating mechanisms 3 can also be set comprehensively according to actual needs and the volume of the razor 1000, such as two, four, etc.

[0066] Preferably, the multiple cutter head seats 2 are evenly spaced along the circumferential direction of the axis x of the base 1, so that the multiple cutter head seats 2 are evenly distributed along the circumferential direction of the axis x of the base 1. While expanding the shaving area, it improves the uniformity of the shaving area distribution, enhances the shaving efficiency, balances the vibration of each razor assembly 21 during the operation of the razor 1000, and further improves the stability of the cutter head assembly 100.

[0067] As Figures 4 to 6 shown, the base 1 has a connecting portion 11, and the cutter head seat 2 has a rotating portion 22. The connecting portion 11 and the rotating portion 22 are rotatably connected. In this way, through the cooperation of the connecting portion 11 and the rotating portion 22, the cutter head seat 2 can rotate relative to the base 1, so that the cutter head seat 2 can deflect in a specific direction under the action of an external force and reset after the external force is removed.

[0068] The angle range for the cutter head seat 2 to rotate around the connecting portion 11 is 0 to 15°. This angle range can ensure that the cutter head seat 2 can deflect relative to the axis x of the base 1 to make the razor assembly 21 have a better fit with the user's face, and also avoid excessive deflection of the cutter head seat 2 to ensure appropriate fitting elasticity, prevent the cutter head seat 2 from deflecting too much during shaving, effectively balancing the requirements of the deflection flexibility and structural stability of the cutter head seat 2, and improving the comfort and safety of the user during use.

[0069] Of course, the cutter head seat 2 rotates around the connecting portion 11, that is to say, the angle of rotation of the cutter head seat 2 around the connecting portion 11 is >0°, and the maximum angle of rotation of the cutter head seat 2 around the connecting portion 11 is 15°. Here, the angle of rotation of the cutter head seat 2 around the connecting portion 11 refers to the angle of downward deflection of any point on the cutter head seat 2 except the rotating portion 22 around the connecting portion 11 relative to the axis x of the base 1.

[0070] In a specific embodiment, the floating mechanism 3 is a torsion structure, and the rotation axes of the connecting portion 11 and the rotating portion 22 penetrate through the torsion structure. The so-called penetration means that the rotation axes of the connecting portion 11 and the rotating portion 22 are collinear with the rotation axis of the torsion structure. The torsion structure acts on the cutter head seat 2 and the base 1 and provides a torsional force to enable the cutter head seat 2 to rotate or reset relative to the base 1.

[0071] By adopting a torsion structure as the floating mechanism 3 and making the rotation axes of the connecting portion 11 and the rotating portion 22 penetrate through the torsion structure, when the cutter head seat 2 deflects under an external force, the torsion structure will store energy; after the external force is removed, the torsion structure releases energy and provides a torsional force to reset the cutter head seat 2. This torsion structure provides a uniform damping force for the deflection of the cutter head seat 2, making the deflection of the cutter head group smoother. At the same time, the structure is simple and compact, which can effectively reduce wear and fatigue and improve the service life of the floating mechanism 3.

[0072] Specifically, the torsion structure can be a torsion spring, a torsion rubber or other components that can provide a torsional force, and its installation position is set so that the rotation axes of the connecting portion 11 and the rotating portion 22 are collinear with the rotation axis of the torsion structure.

[0073] Refer Figures 4 to 6 As shown, in another specific embodiment, the floating mechanism 3 is a linear reciprocating structure 31. One end of the linear reciprocating structure 31 is rotatably connected to the cutter head seat 2, and the other end of the linear reciprocating structure 31 is rotatably connected to the base 1. The linear reciprocating structure 31 provides a reciprocating force to enable the cutter head seat 2 to rotate or reset relative to the base 1.

[0074] In this way, the linear reciprocating structure 31 is connected to the cutter head seat 2 and the base 1 through the rotatable connection points at its two ends, forming a kinematic chain. When the cutter head seat 2 deflects relative to the base 1, the linear reciprocating structure 31 can provide a reciprocating force to control the deflection movement and achieve the reset function. This structure can provide more precise floating control, keep the cutter head in a suitable fitting state at all times, is more stable than the torsion structure, and can provide a more stable reset force, reducing the deflection deviation of the cutter head seat 2 during use.

[0075] Specifically, the base 1 further has a pivoting portion 12. The pivoting portion 12 and the connecting portion 11 are arranged at an interval in the up-and-down direction along the axis of the base 1. The cutter head seat 2 has a fixing portion 23 that is farther from the base 1 than the rotating portion 22. One end of the linear reciprocating structure 31 is rotatably connected to the fixing portion 23, and the other end of the linear reciprocating structure 31 is rotatably connected to the pivoting portion 12. In this way, when the cutter head assembly 100 is under the action of an external force, the fixing portion 23 moves toward the pivoting portion 12, and when the external force is removed, the fixing portion 23 moves away from the pivoting portion 12.

[0076] Wherein, the fixing portion 23 has an initial position and a limit position. When the fixing portion 23 moves from the initial position to the limit position, the angle by which the cutter head seat 2 rotates around the connecting portion 11 of the base 1 is ≤ 15°.

[0077] The linear reciprocating structure 31 includes an elastic member 311. The elastic member 311 is arranged between the cutter head seat 2 and the base 1; under the action of an external force, the cutter head seat 2 can overcome the elastic force of the elastic member 311 and deflect close to the base 1; after the external force is removed, the elastic force of the elastic member 311 allows the cutter head seat 2 to deflect away from the base 1 and reset. 73>

[0078] The elastic member 311 can provide a reliable elastic restoring force for the cutter head seat 2, ensuring that the razor 1000 can return to the initial position after use, while simplifying the structure and reducing the manufacturing cost; in addition, the setting of the elastic member 311 enables the cutter head seat 2 to always maintain an appropriate pressure, improving the shaving effect.

[0079] In this embodiment, the elastic member 311 is a spring; of course, in other embodiments, the elastic member 311 can also be an elastic rubber block or other elements that can provide an elastic restoring force.

[0080] Refer Figures 5 to 6 As shown, the linear reciprocating structure 31 includes a first support member 312. The first support member 312 is connected to the base 1 or the cutter head seat 2.

[0081] In this embodiment, in the circumferential direction of the elastic member 311, the first support member 312 covers at least part of the elastic member 311. Thus, the first support member 312 can play a role in guiding and protecting the elastic member 311, preventing the elastic member 311 from undergoing lateral deformation or detachment during the working process, and ensuring the stability of the deflection of the cutter head seat 2 relative to the axis x of the base 1.

[0082] In another embodiment, the elastic member 311 is sleeved on the first support member 312. That is, the elastic member 311 is sleeved on the outer periphery of the first support member 312, and in the deformation direction of the elastic member 311, the elastic member 311 protrudes from the first support member 312. In this way, the first support member 312 can play a role in guiding and protecting the elastic member 311, preventing the elastic member 311 from undergoing lateral deformation or detachment during operation, and ensuring the stability of the deflection of the tool head seat 2 relative to the axis x of the base 1.

[0083] In this case, the maximum angle of rotation of the tool head seat 2 relative to the base 1 around the connecting portion 11 can also be limited by the length of the first support member 312.

[0084] See Figures 5 to 6 As shown, the linear reciprocating structure 31 further includes a second support member 313. One of the first support member 312 and the second support member 313 is rotatably connected to the base 1, and the other is rotatably connected to the tool head seat 2. The elastic member 311 is disposed between the first support member 312 and the second support member 313.

[0085] Under the action of an external force, the second support member 313 relatively compresses the elastic member 311; after the external force is removed, the elastic member 311 rebounds and abuts against the second support member 313.

[0086] In this way, through the mutual cooperation of the first support member 312, the second support member 313 and the elastic member 311, a complete support structure is formed, which can realize the control of the compression and rebound of the elastic member 311, improve the response sensitivity of the floating mechanism 3. This design optimizes the force transmission path, improves the floating efficiency and service life.

[0087] One of the first support member 312 and the second support member 313 is provided with a chute 313, and the other is provided with a clamping portion 314. The clamping portion 314 is located in the chute 313 and can slide along the chute 313. In this way, the design of the chute 313 and the clamping portion 314 enables the two support members to relatively slide in a specific direction during the floating process, while restricting the movement in an unexpected direction, improving the stability and reliability of the floating mechanism 3; this design not only simplifies the assembly process, facilitates production and maintenance, but also can effectively control the floating direction and prevent the tool head seat 2 from tilting during the deflection process.

[0088] See Figures 5 to 6 As shown, in this embodiment, the first support member 312 has a limiting portion 3121, the limiting portion 3121 defines a receiving cavity, the elastic member 311 is located in the receiving cavity, and the second support member 313 is fitted to the limiting portion 3121 and can move relative to the limiting portion 3121 along the deformation direction of the elastic member 311. In this way, it can prevent the elastic member 311 from undergoing lateral deformation or detachment during operation, and ensure the stability of the deflection of the tool head seat 2 relative to the axis x of the base 1.

[0089] The limiting portion 3121 includes a plurality of arc-shaped plates 31211 which are arranged at intervals along the circumferential direction of the accommodating cavity. This facilitates the mating of the second support member 313 in the limiting portion 3121. During assembly, by applying force to slightly deform the plurality of arc-shaped plates 31211 outward, the second support member 313 can be mated in the limiting portion 3121.

[0090] The arc-shaped plate 31211 is provided with a sliding groove 313 which extends along a direction parallel to the deformation direction of the elastic member 311. The second support member 313 has a clamping portion 314 which is mated in the sliding groove 313 and can move along the sliding groove 313.

[0091] Of course, in other embodiments, the arrangement positions of the limiting portion 3121 and the clamping portion 314 can also be interchanged. That is, the limiting portion 3121 is provided on the second support portion, and the clamping portion 314 is provided on the first support portion.

[0092] Refer Figures 4 to 6 As shown, in this embodiment, the base 1 has a base plate 13 and a fixing member 14 extending perpendicular to the base plate 13. A pair of connecting portions 11 are provided at intervals on the fixing member 14. The pivoting portion 12 is provided on the base plate 13 and is located between the pair of fixing members 14. Thus, the stability of the connection between the tool head seat 2 and the base 1 can be improved, forming a stable support for the tool head seat 2.

[0093] The pivoting portion 12 is located outside the fixing member 14; in the arrangement direction of the rotating portion 22 and the fixing portion 23, the distance between the connecting portion 11 and the pivoting portion 12 is less than the distance between the rotating portion 22 and the fixing portion 23. Thus, the deflection direction of the tool head seat 2 can be made substantially consistent with the deformation direction of the elastic member 311, thereby avoiding lateral deformation or detachment of the elastic member 311 when the tool head seat 2 deflects relative to the axis x of the base 1.

[0094] The fixing member 14 includes a pair of fixing plates 141 arranged at intervals. The connecting portion 11 is an opening provided on the upper side of the fixing plate 141; the tool head seat 2 is located above the fixing member 14 and has a pair of lug ears extending downward. The rotating portion 22 is a rotating shaft protruding from the lug ears. Thus, the rotatable connection between the connecting portion 11 and the rotating portion 22 is achieved, and the structure is simple.

[0095] Refer Figures 2 to 3As shown, a limiting member 4 is provided between adjacent cutter head seats 2, and the limiting member 4 is connected to the base 1; the limiting member 4 is used to limit the deflection angle of the cutter head seat 2, that is, the angle at which the cutter head seat 2 rotates around the connecting portion 11. In this way, when the cutter head seat 2 deflects relative to the axis x of the base 1 to the maximum deflection angle under the action of an external force, the portion of the cutter head seat 2 close to the limiting member 4 will abut against the limiting member 4, thereby restricting the excessive deflection of the cutter head seat 2 relative to the axis x of the base 1; in addition, when the floating mechanism 3 fails, resulting in the excessive deflection of the cutter head seat 2 relative to the axis x of the base 1 or the rotation of the cutter head seat 2 around the axis x of the base 1, the limiting member 4 can prevent collisions between the cutter head seat 2 or the razor assembly 21, thus improving the stability of the razor 1000.

[0096] Specifically, the limiting member 4 can be a structure such as a baffle, a stop block, a protrusion or a stop rod provided on the base 1, and its main function is to prevent the cutter head seat 2 from deflecting excessively under the action of an external force.

[0097] Refer to Figures 1 to 3 As shown, the razor assembly 21 includes a rotary razor 211 and a reciprocating razor 212 arranged at intervals. The rotary razor 211 can perform rotary cutting on short hairs through rotary movement, while the reciprocating razor 212 can effectively cut long beards and curly hairs through reciprocating movement, thereby realizing the composite function of reciprocating movement shaving and rotary movement shaving, achieving efficient processing of hairs of different lengths and types, and improving the shaving experience of users.

[0098] The positive projection of the relatively longer side of the rotary razor 211 and the relatively longer side of the reciprocating razor 212 toward the axis x of the base 1 intersects with the axis x of the base 1. In this way, it can be avoided that the relatively longer sides of the rotary razor 211 and the reciprocating razor 212 are parallel to the axis x of the base 1, resulting in the ineffective operation of the razor assembly 21 when the razor 1000 is working.

[0099] Among them, the so-called positive projection of the relatively longer side of the rotary razor 211 toward the axis x of the base 1 refers to the projection formed by vertically projecting each point on the relatively longer side of the rotary razor 211 onto the same plane passing through the axis x of the base 1; the so-called positive projection of the relatively longer side of the reciprocating razor 212 toward the axis x of the base 1 refers to the projection formed by vertically projecting each point on the relatively longer side of the reciprocating razor 212 onto the same plane passing through the axis x of the base 1.

[0100] Preferably, the relatively longer side of the rotary razor 211 and the relatively longer side of the reciprocating razor 212 are arranged at intervals and parallel to each other, and are both perpendicular to the axis x of the base 1, so as to increase the contact area with the facial contour and improve the shaving efficiency and shaving comfort.

[0101] Refer to Figures 1 to 3As shown, the cutter head assembly 100 further includes a rolling member 5. The rolling member 5 can rotate along its axis, thereby improving smoothness. The razor assembly 21 includes at least two razors. The at least two razors are staggered in the length direction. The rolling member 5 is disposed between two adjacent razors. Thus, not only can the smoothness of the movement of the razor assembly 21 be improved, the shaving comfort be enhanced, and skin damage caused by friction be effectively avoided, but also when the cutter head holder 2 deflects relative to the axis x of the base 1 under the action of an external force, the rolling member 5 has a tendency to move away from the axis x of the base 1 along with the cutter head holder 2, so that it can play a role in tightening the facial skin, enabling the hair roots to be exposed on the skin surface, which is beneficial to the trimming of short hairs by the rotary razor 211 and improving the shaving cleanliness.

[0102] Along the length direction of the rolling member 5, the diameter of at least part of the rolling member 5 is larger than that of other parts. That is to say, the diameter of the rolling member 5 varies in the length direction. Thus, the contact area between the rolling member 5 and the face can be reduced, further improving the smoothness of the movement of the razor assembly 21, and better adapting to the facial contour, thereby enhancing the user experience.

[0103] Refer Figure 1 As shown, the cutter head assembly 100 further includes a housing 6. The housing 6 covers the cutter head holder 2. An opening 61 is provided at one end of the housing 6 away from the cutter head holder 2. Part of the razor assembly 21 is exposed in the opening 61. A smooth area 62 is provided on the surface of the housing 6 away from the cutter head holder 2. Thus, not only can the razor assembly 21 contact the face to achieve shaving, but also the razor 1000 can move more smoothly along the skin, improving the user's comfort. The housing 6 can also protect the cutter head holder 2 and the razor assembly 21, preventing external objects from entering or colliding and damaging the razor assembly 21.

[0104] In this embodiment, smooth balls are provided in the smooth area 62 to facilitate improving the smoothness of the movement of the razor 1000 along the skin.

[0105] In other embodiments, the smooth area 62 can also be made of a material with a low coefficient of friction, or the surface of the smooth area 62 can have a smooth texture to improve the smoothness, reduce the friction with the skin, enhance the use comfort, and make the razor 1000 move more smoothly in various areas of the face.

[0106] In summary, the razor head assembly 100 and the shaver 1000 having it, through the floating mechanism 3, allow the razor head holder 2 to deflect relative to the axis x of the base 1 during shaving, thereby maintaining a good fit between the razor assembly 21 and the user's face, increasing the fit between the shaver 1000 and the face. This allows the shaver 1000 to adaptively adjust its position according to the user's facial contours; it also helps to tighten the facial skin, allowing the hair roots to be better exposed on the skin surface, improving shaving cleanliness, enhancing shaving comfort and experience, reducing pressure on the skin during shaving, and minimizing skin irritation; furthermore, the razor head holder 2 can return to its initial position after the external force is removed for future use.
