Description

Technical Field

[0001] This disclosure relates to the field of razor technology, specifically to a razor head holder; this disclosure also relates to a razor. Background Technology

[0002] An electric shaver is a device that uses an electric motor to rotate the shaving head, thereby cutting human skin and hair. To achieve a comfortable and efficient shaving experience, the cutting part of an electric shaver that comes into contact with the skin needs to have flexible floating or rotating functions to closely conform to the contours of different users' skin.

[0003] However, most traditional electric shavers on the market use the shaver head holder as a fixed fulcrum, allowing the shaver head to only move up and down within a small range, with very limited range of motion. Moreover, with increased use, the springs easily lose their elasticity, causing the shaver head to fail to move properly. This results in uneven pressure on the face during shaving, leading to an uncomfortable user experience. Utility Model Content

[0035] This disclosure provides a razor head holder and a razor, wherein the razor head holder is part of the razor. The razor head holder will be described in conjunction with the description of the specific structure and working principle of the razor below.

[0036] refer to Figure 1 and Figure 2 The razor disclosed herein includes a handle 200, a razor head holder 100, and a razor head assembly 300. The handle 200 can be configured in a shape suitable for holding, allowing the user to perform shaving operations by holding the handle 200. Figure 2 As shown, a battery 2001 and a motor 2002 can be installed in the inner cavity of the handheld part 200. The battery 2001 can supply power to the motor 2002, so that the motor 2002 can provide driving power to the cutter head assembly 300.

[0037] A razor head holder 100 is mounted on a handheld portion 200. The razor head holder 100 includes a first mounting bracket 1, on which a razor head assembly 300 is mounted. Specifically, the razor head holder 100 serves to support the razor head assembly 300 on the handheld portion 200 and to transmit power from the motor 2002 to the razor head assembly 300. The first mounting bracket 1 can be configured as a bowl-shaped structure, thereby providing mounting space for the razor head assembly 300 and some parts of the razor head holder 100.

[0038] In this embodiment, the razor can be a dual-blade razor. The dual-blade design allows for a faster and more thorough shave, and is especially suitable for handling coarse or thick beards. (Reference) Figure 1 The cutter head assembly 300 includes two symmetrically distributed first cutter head components 3001 and second cutter head components 3002; the first mounting bracket 1 is provided with symmetrically distributed first transmission components 601 and second transmission components 602. Under the action of the drive assembly, the first transmission components 601 and second transmission components 602 are configured to drive the first cutter head components 3001 and second cutter head components 3002 to rotate, respectively.

[0039] Specifically, the shaving head assembly 300 includes a shaving head holder 304, which has two through holes for mounting a first shaving head component 3001 and a second shaving head component 3002, respectively. The first shaving head component 3001 and the second shaving head component 3002 can have identical structures. Each shaving head component includes a foil holder 301, a blade foil assembly 302, and a foil retaining ring 303. The foil retaining ring 303 and the foil holder 301 are fixedly installed at the through holes of the shaving head holder 304, clamping the blade foil assembly 302 within them. The blade foil assembly 302 can rotate under the action of the drive component, thereby achieving the shaving function.

[0040] like Figure 1 As shown, the shaver head holder 100 includes a gear carrier 54 installed in the chamber of the first mounting bracket 1. Two through holes can be provided on the gear carrier 54, which are used to install the first transmission component 601 and the second transmission component 602, respectively. Below the gear carrier 54, the shaver head holder 100 also includes a drive assembly for transmission connection with the motor 2002, specifically including: a drive spindle 51, a spindle spring 52, and a spindle gear 53 transmissionally connected to the drive spindle 51. A through hole can be provided at the center of the first mounting bracket 1, allowing the drive spindle 51 to pass downwards and connect to the output shaft of the motor 2002. Under the drive of the motor 2002, the drive spindle 51 drives the spindle gear 53 to rotate. The two ends of the spindle spring 52 abut against the drive spindle 51 and the spindle gear 53, respectively, thereby providing axial cushioning.

[0041] The first transmission component 601 and the second transmission component 602 can have completely identical structures. Each transmission component includes: a blade gear 61, a gear shaft 62, a drive shaft bracket 63, a drive shaft spring 64, and a blade drive shaft 65. The blade gear 61 is located below the gear carrier 54 and meshes with the main shaft gear 53. The gear shaft 62 extends upwards through a through hole in the gear carrier 54 and is connected to the drive shaft bracket 63 and the blade drive shaft 65. The blade drive shaft 65 is configured to be connected to the blade and foil assembly 302. During rotation, the main shaft gear 53 drives the blade and foil assembly 302 to rotate via the blade gear 61, gear shaft 62, drive shaft bracket 63, and blade drive shaft 65, thereby achieving the shaving function. The two ends of the drive shaft spring 64 abut against the drive shaft bracket 63 and the blade drive shaft 65, respectively, thereby providing axial cushioning.

[0042] In one embodiment of this disclosure, such as Figure 1 As shown, the shaver head holder 100 includes a first magnet 7, which is disposed below the gear carrier 54; correspondingly, the shaver head assembly 300 includes a second magnet 305, which is disposed above the shaver head holder 304. When the shaver is fully assembled, the first magnet 7 and the second magnet 305 attract each other, thereby achieving the adsorption and fixation of the shaver head holder 100 onto the shaver head assembly 300.

[0043] The basic structure and working principle of a shaver have been introduced above. The shaver head holder 100 can drive the shaver head assembly 300 to float and rotate relative to the handheld part 200, thereby closely conforming to the skin contours of different users. In conventional electric shavers of the prior art, the shaver head assembly 300 can only float up and down within a small range, and the angle of movement is very limited. To solve this problem, this disclosure provides a new structure for the shaver head holder 100, which will be described in detail below.

[0044] refer to Figures 2 to 4 The shaver head assembly includes a first mounting bracket 1, a second mounting bracket 2, and a floating member 3. The second mounting bracket 2 is connected to the first mounting bracket 1, and the floating member 3 can be mounted on the handheld part 200. The first mounting bracket 1 and the second mounting bracket 2 are configured to rotate relative to the floating member 3 under external force. During shaving, the force of skin pressing against the shaver head assembly 300 causes the first mounting bracket 1 and the second mounting bracket 2 to rotate relative to the floating member 3, that is, relative to the handheld part 200. This allows for flexible and close conformation to the skin contour, reducing missed areas and improving comfort.

[0045] refer to Figure 2For ease of description later, a first direction X1 and a second direction X2 are defined, with the first direction X1 being opposite to the second direction X2. Using the shaver head holder 100 as a reference frame, the direction of the handle 200 is the first direction X1, and the direction of the shaver head assembly 300 is the second direction X2. For a more intuitive understanding, refer to... Figure 2 The view direction is as follows: the bottom is the first direction X1, and the top is the second direction X2.

[0046] refer to Figure 5 The first mounting bracket 1 has a first arcuate surface 101, which is configured to bend toward a first direction X1. (See reference) Figure 11 The second mounting bracket 2 has a second arcuate surface 201, which is configured to bend toward the first direction X1. (See reference) Figure 4 , Figure 8 and Figure 9 The floating component 3 includes a floating head 31 located between the first mounting bracket 1 and the second mounting bracket 2. The floating head 31 is configured to bend toward a first direction X1. The inner wall surface of the floating head 31 is designated as a third arc surface 311. The third arc surface 311 is adjacent to the first mounting bracket 1 and is configured to have the same curvature as the first arc surface 101 for sliding engagement with the first arc surface 101. The outer wall surface of the floating head 31 is designated as a fourth arc surface 312. The fourth arc surface 312 is adjacent to the second mounting bracket 2 and is configured to have the same curvature as the second arc surface 201 for sliding engagement with the second arc surface 201.

[0047] This disclosure utilizes an arc-shaped sliding fit structure between the first mounting bracket 1, the second mounting bracket 2, and the floating component 3, ensuring that all three components bend in the same direction (i.e., the first direction X1) with matching curvatures. This allows the first mounting bracket 1 and the second mounting bracket 2 to rotate flexibly relative to the floating component 3. This design overcomes the limitation of traditional shaver heads only being able to float up and down within a small range, significantly increasing the range of motion of the shaver head holder 100. This allows for better conforming to the skin contours of different users, ensuring even pressure on the face from the head assembly 300 during shaving and improving user comfort. The precise sliding fit between the first arc surface 101 and the third arc surface 311, and between the second arc surface 102 and the fourth arc surface 312, guarantees the stability and smoothness of the rotation process, preventing wobbling or jamming. Furthermore, this disclosure achieves the floating of the shaver head holder 100 without relying on springs, reducing functional failures caused by spring elasticity loss, extending the service life of the shaver head holder 100, and enhancing the reliability of the shaver product. Furthermore, this disclosure directly uses the inner and outer wall surfaces of the floating head 31 as the third arc surface 311 and the fourth arc surface 312, respectively. This eliminates the need for additional independent arc surface components, reducing the number of parts and assembly steps, making the overall structure of the floating component 3 more compact, reducing the possibility of assembly errors, and improving production efficiency. Regarding fit accuracy, this disclosure directly utilizes the surface of the floating head 31 itself to form an arc surface, ensuring a more precise positional relationship between the third arc surface 311 and the fourth arc surface 312, avoiding arc surface positioning deviations, and thus guaranteeing the stability and smoothness of the sliding fit with the first arc surface 101 and the second arc surface 201.

[0048] In one embodiment of this disclosure, reference is made to Figures 5 to 7 The first mounting bracket 1 includes a main body 11, a mating part 12, and a connecting part 13 for connecting the main body 11 and the mating part 12. For example... Figure 6 As shown, the main body 11 has a mounting opening 111, and the connecting part 13 is configured to fix the mating part 12 in the mounting opening 111. The first arc surface 101 is the end face of the mating part 12 facing the floating head 31. The main body 11 is used to form a stable outer shell structure, thereby providing overall support; the mating part 12 is mainly used to form the first arc surface 101 that mates with the floating head 31, ensuring the accuracy of the arc surface sliding fit; one end of the connecting part 13 is connected to the inner sidewall of the mounting opening 111, and the other end is connected to the outer sidewall of the mating part 12, thereby stably connecting the mating part 12 inside the main body 11.

[0049] The main body 11, mating part 12, and connecting part 13 can be integrally formed or they can be designed separately, manufactured separately, and then assembled to form the first mounting bracket 1. In specific embodiments where the first mounting bracket 1 is not integrally formed, for example, in a design where the main body 11 and mating part 12 are designed separately, different materials or processes can be used for different parts. For example, the main body 11 can focus on structural strength, while the mating part 12 can focus on wear resistance, thereby optimizing performance while reducing overall cost and extending the service life of the shaver head holder 100.

[0050] In one embodiment of this disclosure, reference is made to Figure 7 and Figure 10At least two connecting portions 13 are provided. Two adjacent connecting portions 13 are configured to enclose a through opening 14 together with the inner wall of the main body 11 and the outer wall of the mating portion 12. A portion of the second mounting bracket 2 and / or a portion of the floating member 3 are configured to extend into the through opening 14. In addition to fixing the mating portion 12 to the main body 11, the connecting portions 13 also form the through opening 14. The through opening 14 provides extension space for a portion of the structure of the second mounting bracket 2 and the floating member 3, realizing compact assembly of each component, greatly improving space utilization, and avoiding a bulky overall structure. The existence of the through opening 14 maintains sufficient movement clearance, ensuring that the first mounting bracket 1 and the second mounting bracket 2 can rotate flexibly relative to the floating member 3, so that the shaver head holder 100 can stably support the shaver head assembly 300 and adapt to the skin, improving shaving comfort and structural reliability.

[0051] In one specific embodiment of this disclosure, in the first direction X1, the projected area of ​​the mating part 12 in the mounting port 111 accounts for 23%-43%. Within this range, the mating part 12 can form a sufficiently large first arc surface 101 area, thereby significantly increasing the sliding contact area with the third arc surface 311 of the floating head 31, making the contact between the two more sufficient, effectively dispersing the force, avoiding excessive concentration of local wear, and greatly enhancing the stability during the floating process, reducing swaying or displacement, and making the rotation of the first mounting bracket 1 relative to the floating member 3 smoother. In addition, the reasonable area ratio provides sufficient space in the mounting port 111 for forming a through port 14, which facilitates the assembly of the extension of the second mounting bracket 2 or the floating member 3 through the through port 14, avoiding structural interference.

[0052] In one embodiment of this disclosure, reference is made to Figure 3 , Figure 8 and Figure 10 The floating member 3 is located on the first mounting frame 1 in the first direction X1. The floating head 31 is provided with at least two limiting portions 32 extending in the second direction X2. The limiting portions 32 are configured to pass through the through-hole 14, and the side wall 131 of the connecting portion 13 is configured to restrict the rotational freedom of the first mounting frame 1. The limiting portions 32 passing through the through-hole 14 form a reliable hard limiting structure, effectively constraining the rotation range of the first mounting frame 1 relative to the floating member 3, preventing failure of the fit between components or structural damage due to excessive rotation. Simultaneously, the fit between the limiting portions 32 and the through-hole 14 is simple and direct. When rotated to the limit position, the limiting portions 32 abut against the side wall 131 of the connecting portion 13, thereby preventing the first mounting frame 1 from further rotating relative to the floating member 3. This disclosure eliminates the need for additional complex limiting components, simplifying the structure while ensuring the accuracy of the limiting, making the rotation process flexible and controllable, and improving the reliability and safety of product use.

[0053] In one embodiment of this disclosure, the number of connecting portions 13, through-holes 14, and limiting portions 32 are equal. This equality ensures that each limiting portion 32 corresponds to a matching through-hole 14 and connecting portion 13, avoiding imbalance due to mismatch in quantity. At least two connecting portions 13 and at least two through-holes 14 are respectively configured to be symmetrically distributed along the circumferential direction of the mating portion 12; and / or, at least two limiting portions 32 are configured to be symmetrically distributed along the circumferential direction of the floating head 31. The symmetrical distribution makes the limiting force in each direction basically uniform and consistent, preventing the first mounting bracket 1 from tilting or jamming due to uneven force during rotation, ensuring a smooth and stable rotation process. In addition, the symmetrical design can also disperse the impact force during limiting, reduce the wear of local parts, extend the service life of the shaver head holder 100, and improve the overall stability of the structure, making the shaving process safer and more reliable.

[0054] In one specific embodiment of this disclosure, such as Figure 10 As shown, four connecting portions 13, through openings 14, and limiting portions 32 are provided. The four limiting portions 32 can extend into the four through openings 14 one-to-one, and each limiting portion 32 has a connecting portion 13 on each opposite side in the rotation direction. During rotation relative to the first mounting frame 1 along the first rotation direction S1, the limiting portion 32 can abut against the side wall 131 of the connecting portion 13 located on its first rotation direction S1 side. During rotation relative to the first mounting frame 1 along the second rotation direction S2 (the second rotation direction S1 is opposite to the first rotation direction S2), the limiting portion 32 can abut against the side wall 131 of the connecting portion 13 located on its second rotation direction S2 side. In this embodiment, the dimension of the through opening 14 in the rotation direction corresponds to the maximum rotation angle of the first mounting frame 1.

[0055] In another embodiment, the four limiting portions 32 can extend into the two symmetrically arranged through openings 14 in pairs. Specifically, in the circumferential direction, the four limiting portions 32 are sequentially designated as the first limiting portion 321, the second limiting portion 322, the third limiting portion 323, and the fourth limiting portion 324; wherein the first limiting portion 321 and the second limiting portion 322 are located in one of the through openings 14, and the third limiting portion 323 and the fourth limiting portion 324 are located in the other symmetrical through opening 14. During rotation relative to the first mounting frame 1 in the first rotation direction S1, the first limiting portion 321 and the third limiting portion 323 are configured to abut against the side wall 131 of the connecting portion 13; during rotation relative to the first mounting frame 1 in the second rotation direction S2, the second limiting portion 322 and the fourth limiting portion 324 are configured to abut against the side wall 131 of the connecting portion 13.

[0056] It should be noted that, since the razor in this embodiment is a double-headed razor, a first mounting bracket 1 with an approximately elliptical shape is used accordingly. However, the mounting opening 111 on its main body 11 is approximately circular. The four connecting parts 13 are asymmetrically distributed due to the difference in shape between the first mounting bracket 1 and the mounting opening 111, thus forming two larger and two smaller through openings 14. The limiting part 32 is selected to extend into the larger through opening 14 and is configured in pairs. This can make full use of the larger space to achieve a more stable limiting fit and avoid the first mounting bracket 1 having too small a rotation angle due to space constraints.

[0057] Furthermore, in the first rotation direction S1, the first limiting part 321 and the third limiting part 323 abut against the side wall 131 of the connecting part 13; in the second rotation direction S2, the second limiting part 322 and the fourth limiting part 324 abut against the side wall 131 of the connecting part 13. This makes the limiting force evenly distributed along the axis of symmetry of the elliptical structure of the first mounting frame 1, effectively balancing the force when rotating in different directions, preventing local wear or limiting failure caused by excessive or weak limiting force on one side, and ensuring that the rotation range of the first mounting frame 1 relative to the floating member 3 is stably limited within a reasonable range.

[0058] In one embodiment of this disclosure, reference is made to Figure 4 , Figure 7 and Figure 11 The main body 11 has a slot 15 near the through opening 14. Specifically, the slot 15 can be a stepped surface structure near the through opening 14. The second mounting bracket 2 is located on the first mounting bracket 1 in the first direction X1. The second mounting bracket 2 has at least two fasteners 21 extending in the second direction X2. The fasteners 21 are configured to pass through the through opening 14 and engage with the slot 15. Specifically, the fasteners 21 can have a buckle-like structure that can stably engage with the slot 15 (stepped surface), thereby achieving a fixed connection between the first mounting bracket 1 and the second mounting bracket 2. The design of the fasteners 21 extending in the second direction X2 and passing through the through opening 14 makes full use of the space layout of the through opening 14, making the connection structure more compact and eliminating the need for additional installation space.

[0059] In one embodiment of this disclosure, the number of connecting parts 13, through openings 14, slots 15, and fasteners 21 are equal. This equal number ensures that each fastener 21 corresponds to a matching slot 15 and through opening 14, avoiding force imbalance caused by a mismatch in the number of components. Specifically, four connecting parts 13, through openings 14, slots 15, and fasteners 21 may be provided.

[0060] At least two connecting portions 13, at least two through openings 14, and at least two slots 15 are respectively configured to be symmetrically distributed along the circumferential direction of the mating portion 12; and / or, at least two fixing members 21 are configured to be symmetrically distributed along the circumferential direction of the second mounting bracket 2. The symmetrical distribution ensures that the force at each connecting point is evenly distributed along the circumferential direction, and the connection strength in each direction is basically consistent. This prevents damage due to excessive force at local connecting points or failure of fixation due to insufficient force at local connecting points, thereby improving the durability of the connection and enhancing the overall reliability of the shaver head holder 100.

[0061] In one embodiment of this disclosure, see Figures 2 to 4 and Figure 12 An elastic member 4 is disposed between the first mounting bracket 1 and the floating member 3. The first mounting bracket 1 and the second mounting bracket 2 are configured to have a motion component relative to the floating member 3 in a first direction X1 under the action of an external force, and are configured to be able to return to their original position under the action of the elastic member 4. Specifically, the elastic member 4 includes an elastic pleat 42, and it may be made of elastic materials such as silicone or rubber. The elastic member 4 can provide at least a rebound force in the second direction X2. When the first mounting bracket 1 and the second mounting bracket 2 move relative to the floating member 3 in the first direction X1 under the action of an external force (it can move vertically downward or obliquely), the elastic member 4 is deformed by compression; when the external force is removed, the elastic member 4 drives the first mounting bracket 1 and the second mounting bracket 2 to return to their original position. The vertical floating function allows the shaver head holder 100 to better adapt to the ups and downs of the face, reduce local pressure during shaving, and improve the comfort of the fit. In addition, the flexible return characteristic of the elastic member 4 can buffer the impact of external forces, reduce rigid wear between components, and extend the service life of the shaver head holder 100.

[0062] In one embodiment of this disclosure, the elastic member 4 is configured to be sleeved on the second mounting bracket 2 to form a first assembly. The first assembly is configured to be sleeved on the floating member 3 so that the inner wall of the elastic member 4 mates with the floating member 3. Afterward, the fixing member 21 on the second mounting bracket 2 can be snapped into the slot 15 through the through-hole 14, thereby achieving assembly. The elastic member 4 is stably clamped between the second mounting bracket 2 and the floating member 3, ensuring uniform elastic force distribution and avoiding excessive or insufficient local elastic force due to installation misalignment. The tight fit between the elastic member 4 and the inner wall of the floating member 3 reliably transmits the reset elastic force and allows for flexible deformation with the floating motion, ensuring the smooth operation of the first mounting bracket 1 and the second mounting bracket 2 during floating and reset processes, and improving structural stability.

[0063] In one embodiment of this disclosure, reference is made to Figure 8 , Figure 9 , Figure 12 and Figure 13The floating member 3 also includes a mounting base 33 and a positioning rib 34 for connecting the floating head 31 and the mounting base 33. The mounting base 33 is located on the first direction X1 side of the floating head 31. Specifically, the mounting base 33 can be constructed as a cylinder and is used to connect with the handheld part 200. The elastic member 4 is provided with a positioning groove 41, and the positioning rib 34 is constructed to be located within the positioning groove 41 to restrict the rotational freedom of the elastic member 4. The elastic member 4 is sleeved on the second mounting bracket 2 and can rotate relative to the floating member 3 together with the first mounting bracket 1 and the second mounting bracket 2. This disclosure achieves a flexible limiting and buffering protection function by cooperating between the positioning rib 34 of the floating member 3 and the positioning groove 41 of the elastic member 4, thereby restricting the rotational freedom of the elastic member 4.

[0064] Specifically, the structure of the positioning rib 34 embedded in the positioning groove 41 precisely constrains the circumferential rotation of the elastic member 4. The elastic member 4, made of silicone or rubber, is flexible, providing a buffering effect during the limiting process, reducing the rigid collisions of traditional hard limiting and lowering the risk of component wear. Furthermore, the integrated design of the mounting base 33 and the positioning rib 34 enhances the structural strength of the floating member 3, ensuring that the positioning rib 34 can stably withstand the limiting force of the elastic member 4, thus balancing limiting reliability with buffer protection.

[0065] In one embodiment of this disclosure, at least two positioning grooves 41 and positioning ribs 34 are provided, and the number of positioning grooves 41 and positioning ribs 34 is equal. This improves the balance between limiting and buffering, and the equal number ensures that each positioning rib 34 can correspond to a matching positioning groove 41, avoiding unilateral force due to mismatch. Specifically, four positioning grooves 41 and four positioning ribs 34 can be provided.

[0066] In one embodiment of this disclosure, at least two positioning grooves 41 are configured to be symmetrically distributed along the circumferential direction of the elastic member 4, and at least two positioning ribs 34 are configured to be symmetrically distributed along the circumferential direction of the floating member 3. For example, in the embodiment where four positioning grooves 41 and four positioning ribs 34 may be provided respectively, the four positioning grooves 41 are configured to be uniformly distributed along the circumferential direction of the elastic member 4, and the four positioning ribs 34 are configured to be uniformly distributed along the circumferential direction of the floating member 3.

[0067] The symmetrically distributed positioning grooves 41 and positioning ribs 34 ensure that the circumferential limiting force is evenly distributed and the buffering force in each direction is basically consistent, preventing the positioning ribs 34 or positioning grooves 41 from deforming due to excessive local force. At the same time, it ensures the stability of the first mounting bracket 1, the second mounting bracket 2 and the elastic component 4 during rotation relative to the floating component 3, reduces skewing or jamming, and improves the smooth experience during shaving.

[0068] In one embodiment of this disclosure, the first mounting bracket 1 and the second mounting bracket 2 can rotate at a maximum angle of 30-60° relative to the floating member 3. Specifically, the maximum angle range can be defined by the aforementioned rigid limit (the limiting part 32 cooperates with the side wall 131 of the connecting part 13) and the flexible limit (the positioning groove 41 cooperates with the positioning rib 34). The rotation range of 30-60° can avoid component failure or structural damage due to excessive rotation angle, while being sufficient to meet the needs of fitting different facial contours and ensure that the blade can flexibly fit the user's face. When rotating to near the maximum angle, the elastic member 4 can provide cushioning to reduce the impact force when the rigid limit contacts, reduce component wear, and extend service life.
