Abstract
Description
Technical Field
[0001] This utility model relates to the field of household appliances, and in particular to a manual razor. Background Technology
[0002] Existing manual shavers on the market include those with rotating heads. These shavers automatically adjust their angle during shaving through multi-degree-of-freedom rotation or elastic oscillation. The rotating head generates torque through the deformation of elastic components, causing the head to automatically return to its original position after rotation. Current rotating heads utilize flexible bases made of different materials and springs extending from these bases. The connection between the base and the spring requires special processes, such as injection molding inserts or adhesive bonding. Furthermore, injection molding inserts involve complex designs, and differences in the melting temperature and shrinkage rate of the two materials can lead to dimensional deviations. Adhesive bonding requires additional processing, and the adhesive is susceptible to environmental influences, potentially leading to delamination over time. Additionally, the connection between the base and the spring is prone to cracking over extended use, affecting lifespan and reducing user experience. Utility Model Content
[0003] To solve the above problems, this utility model provides a manual razor that, by setting a rotating component, enables the razor head assembly to swing left and right and return to center relative to the handle.
[0004] A manual razor includes: a razor head assembly, the razor head assembly including a razor head and a rotating part, the razor head being connected to the rotating part, the rotating part including a mounting part and a rotating member mounted on the mounting part, the rotating member including an elastic member and two elastic arms connected to the elastic member, the two elastic arms being disposed on both sides of the elastic member; The handle is rotatably connected to the rotating part to allow the cutter head assembly to swing left and right about the first axis. The axis of the elastic element is the same as the first axis, and the first axis is perpendicular to the axis of the handle; The mounting part is provided with a mounting groove, the rotating component is disposed in the mounting groove, and the mounting part is also provided with a second limiting structure for limiting the pop-out of the rotating component; the handle is provided with a first limiting structure that cooperates with limiting the rotating component.
[0005] The advantages are that the mounting section incorporates a rotating component, a limiting structure, and a positioning structure, allowing the cutter head assembly to swing left and right relative to the handle and automatically return to center, providing a comfortable force experience for the user. The structure is simple and reliable. Furthermore, the first limiting structure enables the cutter head assembly to automatically return to center after swinging left and right in a simple manner; and the second limiting structure enhances the reliability of the cutter head assembly's left and right swinging process, preventing the rotating component from disengaging from its position.
[0006] Preferably, the second limiting structure is located above the mounting groove and at least above the elastic arm, and the elastic arm cooperates with the second limiting structure.
[0007] The advantage is that when the cutter head assembly swings left and right relative to the handle after being subjected to force, it will generate elastic deformation, that is, elastic potential energy. When the force disappears, the elastic potential energy is released. Through the cooperation of the elastic arm and the second limiting structure, the displacement of the elastic arm along the first axis is restricted. In particular, it is prevented from the rotating part from falling out of the mounting groove during the release of elastic potential energy, which would cause the function to fail.
[0008] Preferably, the elastic arm abuts against the sidewall of the mounting groove to limit the lateral deformation of the elastic arm.
[0009] The advantage is that it allows the cutter head assembly to swing left and right relative to the handle after being subjected to force. When the force is removed, the elastic potential energy is released, causing the cutter head assembly to return to the center position. The side wall of the mounting groove restricts the force generated by the release of elastic potential energy on the rotating parts after the force is removed, preventing the rotating parts from falling out of the mounting groove and further improving reliability.
[0010] Preferably, the first limiting structure includes a limiting block disposed on the inner wall of the handle, the number of the limiting blocks being the same as the number of the elastic arms, the limiting blocks extending obliquely from top to bottom away from the axis of the handle, and the elastic arms abutting against the inner sidewall of the limiting blocks.
[0011] The advantage is that the elastic arm abuts against the inner wall of the limiting block. When the cutter head assembly is subjected to force, the inner wall can compress the elastic arm, causing the elastic arm to generate elastic potential energy, thereby enabling the mounting part to swing left and right around the first axis. When the force disappears, the elastic arm releases the elastic potential energy, causing the cutter head assembly to return to the correct position. The advantage of extending the limiting block by tilting is that it improves the reliability of the limiting and facilitates assembly.
[0012] Preferably, the included angle between the two spring arms is A, where 0° < A ≤ 60°.
[0013] The advantage is that the two elastic arms are designed at an angle, A, which makes it easier for the elastic arms to produce elastic deformation when they cooperate with the first limiting structure. This allows the shaver head assembly to swing under slight force during use, preventing the rotating mounting part from requiring greater force and improving the user experience.
[0014] Preferably, the shaver further includes a positioning structure for positioning the handle when it is assembled with the rotating part; The positioning structure includes a positioning post disposed on the inner wall of the handle and an assembly hole disposed on the mounting part. The positioning post cooperates with the assembly hole, and the elastic element is sleeved on the outer wall of the columnar wall that defines the assembly hole.
[0015] The advantages are that the positioning post and the assembly hole are matched, the structure is simple and the assembly is convenient; the elastic element is sleeved on the outer wall of the columnar wall that limits the assembly hole, the space is arranged reasonably, and the positioning post, the assembly hole and the inner wall of the handle can limit the elastic element, which improves the assembly reliability of the rotating part and the reliability during the working process.
[0016] Preferably, the mounting portion is circular, one of the cutting head and the rotating portion is provided with a magnet, and the other is provided with a magnetic attracting member that cooperates with the magnet. The cutting head includes a connecting member, and a cavity is provided above the mounting portion. The magnet or the magnetic attracting member is located below the cavity. The connecting member extends into the cavity to allow the magnet and the magnetic attracting member to cooperate. The cavity is formed by recessing from the outer edge of the mounting portion near the cutting head toward the handle so that the mounting portion has a circular outline.
[0017] The advantages are that the blade head and the rotating part are magnetically connected, making it easy to replace the blade head, and the connection and use are convenient and the disassembly is simple. In addition, the mounting part is provided with a cavity, which allows the connector to extend into the cavity, making reasonable use of the space in the mounting part and reducing the size of the shaver. The mounting part is circular and the cavity is formed by the depression of the outer edge of the mounting part, giving the mounting part a circular outline. To a certain extent, it has an indicator function, letting the user know that the blade head assembly can swing left and right relative to the handle.
[0018] Preferably, the shaver further includes a spring needle, and the magnet, the magnetic attractor, and the connector are provided with through holes for the spring needle to pass through. The shaver head also includes a blade holder assembly rotatably connected to the connector. The spring needle passes through the through hole and elastically abuts against the blade holder assembly so that the blade holder assembly rotates back and forth about a second axis. The second axis is parallel to the length direction of the blade holder assembly, and the first axis is perpendicular to the second axis.
[0019] The advantage is that it allows the cutter head assembly to rotate left and right, while the elastic needle and the cutter holder assembly elastically abut against each other, causing the cutter holder assembly to rotate back and forth, thus improving the user experience.
[0020] Preferably, the mounting portion includes a first mounting portion and a second mounting portion split along a direction perpendicular to the axis of the handle, the first mounting portion and the second mounting portion are fastened together, the rotating member is disposed on the first mounting portion and / or the second mounting portion, the handle includes a first shell and a second shell split along a direction perpendicular to the axis of the handle, the first shell and the second shell are fixed by a plurality of engaging structures, the engaging structures are disposed inside the handle and spaced apart along the axis of the handle.
[0021] The advantages are a simple structure, convenient assembly, and improved structural reliability. More specifically, the design of the detachable first and second mounting parts facilitates the assembly of components within the mounting parts, improving assembly efficiency; the detachable first and second shells facilitate the assembly of the handle with the mounting part and the rotating part with the handle; and the multiple locking structures enhance the rigidity of the assembled first and second shells, reducing the gap at the joint and preventing the force generated by the rotating part during the left-right swing of the cutter head assembly from widening the gap or even causing the shells to disengage.
[0022] Preferably, the mounting portion is partially located inside the handle and partially exposed, and the portion of the handle that is rotatably connected to the rotating portion is completely located inside the handle; The cutter head assembly also includes a decorative element disposed on the first mounting portion and / or the second mounting portion, and the decorative element is disposed on the portion of the mounting portion that exposes the handle.
[0023] The advantages are that by ensuring the rotating connection between the handle and the rotating part is completely located inside the handle, the internal space of the handle is made efficient, preventing users from frequently touching the rotating connection part and affecting its reliability. In other words, the rotating connection structure is protected, thus improving its reliability. The decorative parts also enhance the aesthetics of the shaver. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

If the specific posture changes, the directional indicator will also change accordingly.
[0027] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.
[0028] like Figure 1-7 As shown, a manual razor includes: A blade assembly 100 includes a blade 1 and a rotating part 2. The blade 1 is connected to the rotating part 2. The rotating part 2 includes a mounting part 3 and a rotating component 4 mounted on the mounting part 3. The rotating component 4 includes an elastic element 401 and two elastic arms 402 connected to the elastic element 401. The two elastic arms 402 are located on both sides of the elastic element 401. Handle 5 is rotatably connected to the rotating part 2 to cause the cutter head assembly 100 to swing left and right about the first axis Y; The axis of the elastic element 401 is the same as the first axis Y, and the first axis Y is perpendicular to the axis of the handle 5; The mounting part 3 is provided with a mounting groove 303, the rotating part 4 is disposed in the mounting groove 303, and the mounting part 3 is also provided with a second limiting structure 7 for limiting the pop-out of the rotating part 4; the handle 5 is provided with a first limiting structure 6 for limiting the outward deformation of the elastic arm 402.
[0029] This configuration, through the cooperation of the rotating component 4, the first limiting structure 6, and the second limiting structure 7, ensures stable movement of the rotating component 4 within the mounting groove 303. This allows the shaver head assembly 100 to swing left and right relative to the handle 5 and automatically return to its original position, improving the shaver's flexibility and safety. It also allows users to adjust the shaver head angle according to their needs, optimizing the shaving experience. Furthermore, the first limiting structure 6 enables the shaver head assembly 100 to automatically return to its original position after swinging left and right in a simple structural manner; and the second limiting structure 7 enhances the reliability of the shaver head assembly 100's left and right swing, preventing the rotating component 4 from disengaging. Further, as... Figure 2 As shown, the second limiting structure 7 is located above the mounting groove 303 and at least above the elastic arm 402, which cooperates with the second limiting structure 7.
[0030] With this configuration, when the cutter head assembly 100 swings left and right relative to the handle 5 after being subjected to force, it will generate elastic deformation, that is, elastic potential energy. When the force disappears, the elastic potential energy is released. Through the cooperation of the elastic arm 402 and the second limiting structure 7, the movement of the elastic arm 402 along the first axis Y is restricted, especially preventing the rotation of the four parts from dislodging from the mounting groove 303 during the process of releasing the elastic potential energy, which would cause the function to fail.
[0031] like Figure 4 , 5 As shown, the elastic arm 402 abuts against the side wall 3031 of the mounting groove 303 to restrict the elastic arm 402 from deforming outward. This configuration allows the cutter head assembly 100 to swing left and right relative to the handle 5 after being subjected to force. When the force disappears, the elastic potential energy releases, causing the cutter head assembly 100 to return to its original position. The side wall 3031 of the mounting groove 303, which restricts the force after the force disappears, exerts a force on the rotating component 4, preventing the rotating component 4 from dislodging from the mounting groove and further improving reliability.
[0032] Furthermore, the first limiting structure 6 includes a limiting block 601 disposed on the inner wall of the handle 5. The number of limiting blocks 601 is the same as the number of elastic arms 402. The limiting blocks 601 extend obliquely from top to bottom in a direction away from the axis of the handle 5. The elastic arms 402 abut against the inner sidewall of the limiting block 501.
[0033] The elastic arm 402 abuts against the inner wall of the limiting block 601. When the cutter head assembly 100 is subjected to force, the inner wall can compress the elastic arm 402, causing the elastic arm 402 to generate elastic potential energy, thereby enabling the mounting part 3 to swing left and right around the first axis. When the force disappears, the elastic arm 402 releases the elastic potential energy, causing the cutter head assembly 100 to return to the center. The advantage of the inclined extension of the limiting block 601 is that it improves the reliability of the limiting and facilitates assembly.
[0034] Furthermore, such as Figure 2 , 4 As shown, the included angle between the two spring arms 402 is A, where 0° < A ≤ 60°. The two spring arms 402 are designed at an angle of A, making it easier for the spring arms 402 to undergo elastic deformation in conjunction with the first limiting structure. This allows the shaver head assembly 100 to swing under slight force during use, preventing the need for greater force to rotate the mounting part 3. When the included angle between the spring arms 402 is greater than 60°, the angle is too large, increasing the rotational resistance and making it difficult for the mounting part 3 to rotate, requiring the user to use greater force to rotate it. In this embodiment, the angle between the spring arms 402 is 60° to provide a comfortable experience in rotating the mounting part 3.
[0035] There are two elastic arms 402, which are connected to the elastic element 401 and integrally formed. Each elastic arm 402 includes a first part 402A and a fourth part 402D close to the elastic element 401, and a second part 402B and a third part 402C away from the elastic element 401. The elastic arms 402 extend from the first part 402A along the mounting groove 303 towards the second part 402B and from the fourth part 402D along the mounting groove 303 towards the third part 402C.
[0036] like Figure 2-7 As shown, the second part 402B and the third part 402C of the elastic arm 402 are set along the limiting block 601. When the cutter head assembly 100 is in the original position, it is the state when the cutter head assembly is not under force. At this time, the elastic arm 402 is not subjected to additional external force.
[0037] When the cutter head assembly 100 is deflected to one side relative to the handle 5, that is, when the rotating part 2 deflects to one side of the first axis Y, the third part 402C of the elastic arm 402 is restricted by the limiting block 601, and the first part 402A of the elastic arm 402 is restricted by the side wall 3031 of the mounting groove 3, so that the elastic arm 402 has elastic potential energy. When the rotating part 2 is to return to the center position, the spring arm 402 releases the elastic potential energy. The first part 402A and the third part 402C of the deformed elastic arm 402 are gradually deformed. Furthermore, the second part 402B of the undeformed elastic arm 402 is restricted by the side wall 3031 of the mounting groove 3, and the fourth part 402D is restricted by the limiting block 601, which can prevent the elastic arm 402 from continuing to release elastic potential energy. Finally, the rotating part 2 returns to the center position, and the cutter head assembly 100 is in the original position.
[0038] When the cutter head assembly 100 is deflected to the other side relative to the handle, that is, when the rotating part 2 deflects to the other side of the first axis Y, the second part 402B of the elastic arm 402 is restricted by the limiting block 601, and the fourth part 402D of the elastic arm 402 is restricted by the side wall 3031 of the mounting groove 3, so that the elastic arm 402 has elastic potential energy. When the rotating part 2 wants to return to the center position, the spring arm 402 releases the elastic potential energy. The deformation of the second part 402B and the fourth part 402D of the deformed elastic arm 402 gradually decreases. Furthermore, by the first part 402A of the undeformed elastic arm 402 being restricted by the side wall 3031 of the mounting groove 3, and the third part 402C being restricted by the limiting block 601, the elastic arm 402 can be prevented from continuing to release elastic potential energy, finally causing the rotating part 2 to return to the center position, and the cutter head assembly 100 to be in the original position. Furthermore, the rotating part 4 is made of stainless steel. The rotating part 4 is a single material, with a simple structure and does not need to be combined with other materials.
[0039] like Figure 4 , 7 As shown, the shaver also includes a positioning structure for positioning the handle 5 when it is assembled with the rotating part 2. The positioning structure includes a positioning post 8 disposed on the inner wall of the handle 5 and an assembly hole 9 disposed on the mounting part 3. The positioning post 8 cooperates with the assembly hole 9, and the elastic member 301 is sleeved on the outside of the columnar wall that defines the assembly hole 9.
[0040] This design, with the positioning post 8 engaging with the mounting hole 9, results in a simple structure and convenient assembly. The mounting part 3 has a mounting hole 9, and the elastic element 401 is fitted onto the outer wall of the columnar wall of the mounting hole 9, arranging the space rationally. The mounting hole 9 is located at the rotation center of the mounting part 3. When the elastic element 401 is positioned around the mounting hole 9, the mounting hole 9 engages with the positioning post 8, and the elastic element 401 is positioned within the mounting groove 303, making it less prone to falling off and easy to disassemble and replace, extending the shaver's lifespan. Furthermore, the elastic element 401 does not require injection molding inserts or adhesive bonding processes with the handle 5, significantly reducing assembly costs. The positioning post 8, the mounting hole 9, and the inner wall of the handle 5 effectively limit the movement of the elastic element 401, improving the assembly reliability of the rotating part 4 and its reliability during operation.
[0041] like Figure 5 , 7 As shown, the mounting portion 3 is circular. One of the cutting head 1 and the rotating portion 2 is provided with a magnet 10, and the other with a magnetic attracting member 13 that cooperates with the magnet 10. In this embodiment, the magnet 10 is disposed within the rotating portion 2, and the magnetic attracting member 13 is disposed within the cutting head 1. The cutting head 1 includes a connecting member 11. A cavity 304 is provided above the mounting portion 3, and the magnet 10 is disposed below the cavity 304. The connecting member 11 extends into the cavity 304 to attract the magnet 10 and the magnetic attracting member 13. The cavity 304 is formed by recessing from the outer edge of the mounting portion 3 near the cutting head 1 towards the handle 5, giving the mounting portion 3 a circular outline. It can be understood that the positions of the magnet 10 and the magnetic attracting member 13 can be interchanged; that is, the magnet 10 can be disposed within the connecting member 11, and the magnetic attracting member 13 can be disposed within the mounting portion 3.
[0042] The magnet 10 cooperates with the magnetic suction member 13 to magnetically connect the mounting part 3 and the blade head 1. This arrangement facilitates the replacement of the blade head 1, and the magnetic connection is convenient to use and easy to disassemble. The mounting part 3 has a recess 304, into which the connecting member 11 extends, making reasonable use of the space in the mounting part 3 and avoiding the need for additional space to set up the magnetic suction structure, thus reducing the size of the shaver. The mounting part 3 is circular, and the recess is formed by the indentation of the outer edge of the mounting part 3, giving the mounting part 3 a circular outline. This provides a certain degree of indication, making the user aware that the blade head assembly can swing left and right relative to the handle.
[0043] like Figure 1 , 3As shown in Figure 5, the shaver also includes a spring needle 12. The magnet 10, the magnetic attractor 13, and the connector 12 are provided with through holes 15 for the spring needle 12 to pass through. The shaver head 1 also includes a blade holder assembly 101 rotatably connected to the connector 11. The spring needle 12 passes through the through hole 15 and elastically abuts against the blade holder assembly 101, allowing the blade holder assembly 101 to rotate back and forth around a second axis X. The second axis X is parallel to the length direction of the blade holder assembly 101, and the first axis is perpendicular to the second axis. This configuration allows the shaver head assembly 100 to rotate left and right while the elastic needle 12 elastically abuts against the blade holder assembly 101, causing the blade holder assembly to rotate back and forth, meeting the user's needs. More specifically, the first axis Y is perpendicular to the length direction of the blade holder assembly 101. The blade is provided on the blade holder assembly 101, with the blade edge positioned along the length direction of the blade holder assembly 101. In this embodiment, the "length direction" actually refers to the extension direction of the blade edge. In this embodiment, the "forward" direction refers to the direction in which the shaving surface of the razor is in contact with the skin to shave the beard; using this direction as a reference, the "backward" direction is the direction opposite to the shaving surface; the "left" direction refers to the left side of the shaving surface, and the "right" direction refers to the right side of the shaving surface. In this embodiment, the razor holder assembly can swing in four directions—forward and backward, left and right—which facilitates close contact with the skin and improves the user experience.
[0044] like Figure 6 , 7 As shown, the mounting part 3 includes a first mounting part 301 and a second mounting part 302 split along a direction perpendicular to the axis of the handle 5. The first mounting part 301 and the second mounting part 302 are fastened together. One of the first mounting part 301 and the second mounting part 302 is provided with a recessed stop 1401, and the other is provided with a convex stop 1402 that cooperates with it. With this configuration, the mounting part 3 is connected in a detachable manner, which is simple in structure and easy to assemble. The rotating part 4 is provided on the first mounting part 301 and / or the second mounting part 302. The handle 5 includes a first shell 501 and a second shell 502 split along a direction perpendicular to the axis of the handle 5. The first shell 501 and the second shell 502 are fixed by a plurality of engaging structures 17. The engaging structures 17 are disposed inside the handle 5 and are spaced apart along the axis of the handle 5.
[0045] This design simplifies the structure, facilitates assembly, and enhances structural reliability. More specifically, the detachable connection between the first mounting part 301 and the second mounting part 302 facilitates the assembly of the internal components of the mounting part 3, improving assembly efficiency. The detachable connection between the first housing 501 and the second housing 502 also facilitates the assembly of the handle 5 with the mounting part 3 and the rotating part 4 with the handle 4. The multiple interlocking structures enhance the stability of the assembled first housing 501 and the second housing 502, reducing the gap at the joint where the first housing 501 and the second housing 502 are fastened. Simultaneously, it prevents the force generated by the rotating part 3 during the left-right swinging of the cutter head assembly 100 from causing the gap at the joint of the first housing 501 and the second housing 502 to widen and disengage.
[0046] Furthermore, the mounting part 3 is partially located inside the handle 5 and partially exposed, while the part of the handle 5 that is rotatably connected to the rotating part 2 is completely located inside the handle 5; The razor head assembly 100 also includes a decorative element 16, which is disposed on the first mounting portion 301 and / or the second mounting portion 302, and the decorative element 16 is disposed on the portion of the mounting portion 3 that exposes the handle 5. This arrangement, by ensuring that the rotatable connection between the handle 5 and the rotating portion 2 is completely located within the handle 5, makes efficient use of the internal space of the handle 5, prevents frequent contact with the rotatable connection portion by the user from affecting reliability, thus protecting the rotatable connection structure and improving its reliability; the decorative element 16 also enhances the aesthetics of the razor.
[0047] The present application has been described above with reference to preferred embodiments; however, these embodiments are merely exemplary and illustrative. Various substitutions and modifications can be made to the present application based on these embodiments, all of which fall within the protection scope of the present application.
