Manual razor

Abstract

This application discloses a manual razor, comprising: a handle; a razor head; a connecting mechanism, which is swayable left and right and mounted on the handle, connecting the razor head; and an elastic component, mounted on the connecting mechanism. The elastic component has two lateral ends connected to the handle, or one end of the elastic component is connected to the handle, and the other end is connected to the connecting mechanism. The elastic component provides an elastic force that allows the connecting mechanism to return to a centered position after swaying left and right. When the razor head is subjected to lateral forces from the facial contour during shaving, causing the connecting mechanism to sway left and right relative to the handle, the elastic component is stretched or compressed accordingly and stores elastic potential energy. Once the lateral force is eliminated, this elastic potential energy drives the connecting mechanism to automatically and accurately return to a stable centered position, ensuring that the razor head sways flexibly and smoothly with timely and reliable return, allowing the razor head to better adapt to the contours of the human face.

Description

Technical Field

[0001] This application relates to the field of razor technology, and more particularly to a manual razor. Background Technology

[0002] Manual razors typically consist of three main parts: a handle, a connecting mechanism, and a razor head. The razor head includes a support, a blade holder, and blades mounted on the blade holder. The connecting mechanism is used to connect the handle and the blade holder, thereby completing the assembly of the razor head and the handle.

[0003] To improve the adaptability of the blade head to the contours of the human face, current designs typically mount the blade holder on the support, allowing it to swing up and down, while the connecting mechanism is mounted on the handle, enabling the blade to swing both vertically and horizontally. However, due to the structural design limitations of existing connecting mechanisms, the blade head often lacks sufficient flexibility in horizontal swinging, thus restricting its effective adaptation to changes in facial contours.

[0024] This utility model discloses a manual razor. By mounting a connecting mechanism that can swing left and right on the handle, and incorporating an elastic component on the connecting mechanism (whose two ends are connected to the handle, or one end is connected to the handle and the other end to the connecting mechanism), the structure utilizes the lateral elastic deformation characteristics of the elastic component to provide restoring force. When the razor head is subjected to lateral forces from the facial contour during shaving, causing the connecting mechanism to swing left and right relative to the handle, the elastic component is stretched or compressed accordingly and stores elastic potential energy. Once the lateral force is eliminated, this elastic potential energy drives the connecting mechanism to automatically and accurately return to a stable, centered position. This ensures that the razor head swings flexibly and smoothly, and returns to its original position promptly and reliably. This allows the razor head to better adapt to the contours of the human face, comprehensively improving shaving closeness, comfort, and operational stability.

[0035] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0036] See Figures 1-6 This invention illustrates a preferred embodiment of a manual razor, comprising:

[0037] Handle 1;

[0038] Blade 2;

[0039] A connecting mechanism 3 is mounted on the handle 1 and can swing left and right. The connecting mechanism 3 connects to the cutter head 2, thereby connecting the cutter head 2 to the handle 1.

[0040] The elastic component 4 is disposed on the connecting mechanism 3. The two lateral ends of the elastic component 4 are respectively connected to the handle 1, or one end of the two lateral ends of the elastic component 4 is connected to the handle 1, and the other end of the two lateral ends of the elastic component 4 is connected to the connecting mechanism 3. The elastic component 4 is used to provide an elastic force that causes the connecting mechanism 3 to return to the center position after swinging left and right.

[0041] This utility model of a manual razor features a connecting mechanism 3 that can swing left and right on the handle 1, and an elastic component 4 (connected to the handle 1 at both ends or to the connecting mechanism 3 at one end) on the connecting mechanism 3. This structure utilizes the lateral elastic deformation characteristics of the elastic component 4 to provide restoring force. When the razor head 2 is subjected to the lateral force of the facial contour during shaving, causing the connecting mechanism 3 to swing left and right relative to the handle 1, the elastic component 4 is stretched or compressed accordingly and stores elastic potential energy. Once the lateral force is eliminated, this elastic potential energy drives the connecting mechanism 3 to automatically and accurately return to a stable central position. This ensures that the razor head 2 swings left and right flexibly and smoothly, and returns to its central position promptly and reliably. This allows the razor head 2 to better adapt to the undulations of the human face, comprehensively improving the closeness, comfort, and operational stability of shaving.

[0042] See Figures 1-6In one embodiment, the handle 1 is provided with a first connecting arm 11 and a second connecting arm 12, which are respectively placed on the upper and lower sides of the connecting mechanism 3.

[0043] The connecting mechanism 3 is equipped with a rotating shaft 5, which extends vertically. The upper end of the rotating shaft 5 is rotatably mounted on the first connecting arm 11, and the lower end of the rotating shaft 5 is rotatably mounted on the second connecting arm 12. By setting the first connecting arm 11 and the second connecting arm 12 on the upper and lower sides of the connecting mechanism 3 respectively on the handle 1, and by setting the vertically extending rotating shaft 5 on the connecting mechanism 3, the upper and lower ends of the rotating shaft 5 are rotatably connected to the first connecting arm 11 and the second connecting arm 12 respectively, forming a double-point rotation structure. This enhances the stability and structural rigidity of the connecting mechanism 3 when swinging left and right, which in turn enhances the stability and structural rigidity of the cutter head 2 when swinging left and right.

[0044] See Figures 1-4 In one embodiment, the first connecting arm 11 is provided with two first connecting parts 111, which are respectively located on the left and right sides of the rotating shaft 5. The rotating shaft 5 has a first slot 51, which passes through the rotating shaft 5 on both the left and right sides.

[0045] The elastic component 4 is a spring sheet that passes through the first slot 51, with both ends of the spring sheet connected to the corresponding first connecting parts 111. By adopting the form of a spring sheet for the elastic component 4, with the spring sheet passing through the first slot 51 on the rotating shaft 5 and both ends of the spring sheet connected to the corresponding first connecting parts 111, the spring sheet is reliably fixed to the handle 1. This structure utilizes the elastic characteristics of the spring sheet's lateral extension. When the shaving head 2 is driven by the lateral force of the facial contour to swing the connecting mechanism 3 around the rotating shaft 5, the spring sheet undergoes elastic deformation and stores potential energy. Once the lateral force is eliminated, the spring sheet releases the potential energy to drive the connecting mechanism 3 to automatically return to the centered position. This solution integrates the swing support and elastic return functions into a single spring sheet component through the integrated design of the spring sheet, rotating shaft 5, and first connecting parts 111, eliminating the need for additional connecting structures, greatly simplifying the overall structure, reducing the number of parts and assembly costs, while ensuring that the shaving head 2 swings flexibly and returns accurately and reliably, allowing it to better adapt to changes in facial contours and improve shaving closeness and comfort.

[0046] For easier fixing of the spring clip, see Figure 4 In one embodiment, the first connecting part 111 has a first limiting groove 1111, and the end of the spring piece is inserted into the corresponding first limiting groove 1111.

[0047] See Figure 4In one embodiment, the first connecting part 111 further has a first connecting hole 1112, the first connecting hole 1112 is perpendicular to the first limiting groove 1111, the first connecting hole 1112 communicates with the first limiting groove 1111, the first connecting hole 1112 is used to connect with a fastening member (not shown in the figure), the fastening member is used to press the end of the spring piece against the side wall of the first limiting groove 1111 to restrict the spring piece from disengaging from the first limiting groove 1111, thereby realizing the reliable fixing of the spring piece to the first connecting part 111.

[0048] Specifically, the fastening component mentioned above can be a bolt.

[0049] See Figures 2-3 In one embodiment, the connecting mechanism 3 is provided with a connecting sleeve 31, which is sleeved on the outside of the rotating shaft 5. The connecting sleeve 31 has a second slot 311, which extends through the connecting sleeve 31 on both the left and right sides. The second slot 311 allows the spring to pass through, enabling the spring to pass laterally through the rotating shaft 5 and allowing the end of the spring to connect with the first connecting part 111. At the same time, the setting of the second slot 311 provides the spring with precise positioning and a stable installation path, ensuring that the spring can produce uniform elastic deformation in a predetermined direction when subjected to force, thereby effectively improving the flexibility of the connecting mechanism 3 in swinging left and right and the timeliness of reset.

[0050] See Figures 5-6 In one embodiment, the first connecting arm 11 is provided with a first connecting part 111, and the connecting mechanism 3 is provided with a second connecting part 32. The second connecting part 32 and the first connecting part 111 are respectively placed on the left and right sides of the rotating shaft 5.

[0051] The elastic component 4 is a torsion spring. The main body of the torsion spring is sleeved outside the rotating shaft 5. The first extension arm of the torsion spring is connected to the first connecting part 111, and the second extension arm of the torsion spring is connected to the second connecting part 32. Specifically, the elastic component 4 is a torsion spring. The main body of the torsion spring is sleeved outside the rotating shaft 5. Its first extension arm is connected to the first connecting part 111, and its second extension arm is connected to the second connecting part 32. This structure utilizes the torsional elasticity of the torsion spring. When the cutter head 2 is driven by a lateral force to swing the connecting mechanism 3 left and right relative to the handle 1, it will drive the second connecting part 32 to move synchronously. This forces the extension arm of the torsion spring (either the first or second extension arm) to undergo torsional deformation within the connecting part (either the first or second connecting part 111 or the second connecting part 32) and store recovery potential energy. After the lateral force disappears, the torsion spring... The spring releases potential energy to drive the connecting mechanism 3 to automatically and accurately return to the center position. This solution integrates the swing support and elastic return function into a single torsion spring component through the tight cooperation between the torsion spring, the rotating shaft 5 and the connecting parts on both sides (first connecting part 111 and second connecting part 32). This avoids the use of additional connecting structures, significantly simplifies the overall structure, reduces manufacturing and assembly costs, and ensures that the blade head 2 swings flexibly and smoothly and the return response is timely and reliable. This allows it to efficiently adapt to the undulations of the human face contour, effectively improving the closeness, comfort and operational stability of shaving.

[0052] See Figures 5-6 In one embodiment, the first connecting part 111 has a first limiting groove 1111, and the second connecting part 32 has a second limiting groove 321.

[0053] The end of the first extension arm of the torsion spring is inserted into the first limiting groove 1111 so that the first extension arm of the torsion spring is reliably connected to the first connecting part 111, and the end of the second extension arm of the torsion spring is inserted into the second limiting groove 321 so that the second extension arm of the torsion spring is reliably connected to the second connecting part 32.

[0054] See Figure 5 In one embodiment, the connecting mechanism 3 is provided with a connecting sleeve 31, which is sleeved on the outside of the rotating shaft 5, and the main body of the torsion spring is sleeved on the outside of the connecting sleeve 31. By providing a connecting sleeve 31 sleeved on the outside of the rotating shaft 5 in the connecting mechanism 3, and sleeved on the outside of the connecting sleeve 31, the connecting sleeve 31 serves as a rigid isolation bushing between the rotating shaft 5 and the torsion spring. This structure utilizes the outer cylindrical surface of the connecting sleeve 31 to provide a uniform and consistent support base for the torsion spring, ensuring the stability of the torsion spring under force and deformation during rotation. At the same time, it effectively avoids direct friction and wear between the torsion spring and the rotating shaft 5. This not only significantly improves the smoothness and rebound consistency of the torsion spring's operation, but also helps to extend the service life of the torsion spring and the rotating shaft 5, and facilitates assembly and maintenance.

[0055] See Figure 4 and Figure 6In one embodiment, the first connecting arm 11 and the second connecting arm 12 are both arranged along the left and right direction of the manual razor. The first connecting arm 11 and the second connecting arm 12 extend in opposite directions. The structural layout of the first connecting arm 11 and the second connecting arm 12 makes full use of the lateral space of the handle 1. At the same time, since the first connecting arm 11 and the second connecting arm 12 extend in opposite directions to form symmetrical lever arms, they provide a bidirectional balanced support torque for the rotating shaft 5 during the swinging process, effectively offsetting the unidirectional off-center load, and enhancing the deformation resistance and swing stability of the connecting mechanism 3 under torsional force.

[0056] See Figure 4 and Figure 6 In one embodiment, the first connecting arm 11 has a second connecting hole 112, and the second connecting arm 12 has a third connecting hole 121. The upper end of the rotating shaft 5 is rotatably inserted into the second connecting hole 112, and the lower end of the rotating shaft 5 is rotatably inserted into the third connecting hole 121. Thus, the second connecting hole 112 and the third connecting hole 121 respectively form precise constraints and coordinated guidance for the upper and lower ends of the rotating shaft 5, ensuring that the rotating shaft 5 maintains a stable axial position during rotation, effectively suppressing radial runout and sway, improving rotational smoothness and motion accuracy, thereby making the left-right swing of the connecting mechanism 3 smoother and more stable.
