Description

Technical Field

[0001] This utility model relates to the field of hair trimmer technology, and more specifically, to a multi-directional moving blade head structure and a manual razor. Background Technology

[0002] Existing manual razors feature blades that can rotate and swing around a support axis relative to the handle base at a certain angle. This allows for a more comfortable grip and a closer fit to the facial contours. However, the rotation direction of these blades is relatively limited, resulting in poor facial contouring. During shaving, the wrist is required to move the blades in multiple directions, making it difficult for users to grip the razor properly and requiring them to constantly adjust their grip and angle depending on the shaving area. This leads to a poor overall comfort and experience. Utility Model Content

[0003] To address at least one of the aforementioned problems, this utility model first provides a multi-directional moving cutter head structure, including a cutter head assembly adapted to connect with a handle base and a rotating component. The cutter head assembly swings relative to the handle base in the left-right direction via the rotating component, and the cutter head assembly is slidably connected to the handle base in the front-back direction. A reset component connected to the cutter head assembly is provided on the handle base. When the cutter head assembly is subjected to force, it is adapted to swing left-right and / or move front-back relative to the handle base. When the force applied to the cutter head assembly is removed, the reset component will drive the cutter head assembly to automatically reset in the left-right direction and / or front-back direction.

[0004] Optionally, the rotating component is a rivet post, which is mounted on the handle base, and the cutter head assembly is rotatably sleeved on the rivet post.

[0005] Optionally, the cutter head assembly is provided with a waist-shaped hole, the extension direction of the waist-shaped hole is the front-to-back direction, and the rivet post is inserted into the waist-shaped hole.

[0006] Optionally, the handle base has a mounting cavity, and the cutter head assembly is inserted into the mounting cavity; the handle base has a connector, and the outer wall of the handle base has a rotating groove, which communicates with the mounting cavity; the connector is inserted into the rotating groove and detachably connected to the cutter head assembly; the cutter head assembly drives the connector to swing left and right within the range of the rotating groove; the connector is arranged at intervals with the groove wall of the rotating groove along the front-back direction.

[0007] Optionally, two reset members are provided, and the two reset members are respectively located on the left and right sides of the rotating member, so as to drive the cutter head assembly to reset in the left and right or / and front and back directions respectively.

[0008] Optionally, the reset element is a spring, a rubber cylinder, or an elastic rope.

[0009] Optionally, the reset element is a spring, the cutter head assembly is provided with a spring groove for the spring to be inserted, and the handle base is provided with a spring post for the spring to be sleeved.

[0010] Optionally, the cutter head assembly includes a cutter head body and a cutter head connecting frame. The cutter head body is rotatably connected to the cutter head connecting frame, and the cutter head body is adapted to swing relative to the cutter head connecting frame in the up-down direction. The cutter head connecting frame is movably connected to the handle base through the rotating member, and the cutter head connecting frame is adapted to drive the cutter head body to move back and forth or swing left and right relative to the handle base.

[0011] Optionally, the cutter head assembly further includes a support tongue and an elastic element. The support tongue is slidably connected to the cutter head connecting frame, and the elastic element is mounted on the cutter head connecting frame and connected to the support tongue. The elastic element is adapted to drive the support tongue to abut against the cutter head body to provide damping force and restoring force after rotation for the cutter head body to rotate up and down.

[0012] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0013] 1. The shaving head assembly can swing left and right relative to the handle base and move back and forth relative to the handle base via a rotating component. At the same time, the shaving head body can swing up and down relative to the handle base, enabling the shaving head body to move in multiple directions relative to the handle base. It can automatically adjust the angle according to the curve of the face, making the grip technique less demanding when shaving, and allowing the shaving head body to fit the face more closely (chin, cheekbone, philtrum, jawline, etc.), resulting in a cleaner shave and improving the comfort and experience of shaving.

[0014] 2. When shaving, the back-and-forth movement of the razor head can act as a buffer, automatically releasing some force, reducing the risk of cuts, and ensuring high safety;

[0015] 3. The reset component can automatically reset the blade assembly after swinging left and right and moving back and forth, reducing the risk of users cutting their faces due to incorrect gripping methods.

[0016] 4. The cooperation between the support tongue and the elastic element can generate a damping force on the up and down rotation of the cutter head body, which restricts the degree of freedom of the cutter head body when rotating up and down, and prevents the cutter head body from rotating too sensitively and cutting the face. At the same time, it can drive the cutter head body to automatically return to the tilted state after rotating up and down.

[0017] In addition, this utility model provides a manual razor, including the multi-directional moving blade head structure as described above.

[0018] Compared to existing technologies, the manual razor described in this utility model has the same advantages as the multi-directional moving blade head structure described above, which will not be repeated here. Attached Figure Description

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the following description is provided in conjunction with the appendix. Figure 1-5 This application will be described in further detail.

[0026] The accompanying drawings of this utility model embodiment provide a coordinate system XYZ, where the positive direction of the X-axis represents the right, the negative direction of the X-axis represents the left, the positive direction of the Y-axis represents the front, the negative direction of the Y-axis represents the back, the positive direction of the Z-axis represents the top, and the negative direction of the Z-axis represents the bottom.

[0027] Firstly, embodiments of this utility model provide a multi-directional moving cutter head structure, referring to... Figure 1 and Figure 2The multi-directional moving cutter head structure includes a cutter head assembly 2 adapted to connect with the handle base 1. The handle base 1 has a rotating member 11, through which the cutter head assembly 2 swings relative to the handle base 1 in the left-right direction, and the cutter head assembly 2 can also move relative to the handle base 1 in the front-back direction. The handle base 1 has a reset member 12 connected to the cutter head assembly 2; when the cutter head assembly 2 is subjected to force, it is adapted to swing left-right and / or move front-back relative to the handle base 1. When the force applied to the cutter head assembly 2 is removed, the reset member 12 will drive the cutter head assembly 2 to automatically reset in the left-right and / or front-back direction. In another embodiment, the rotating member 11 can be fixedly mounted on the cutter head assembly 2, but the rotating member 11 is rotatably connected to the handle base 1.

[0028] The front end of the handle base 1 has a mounting cavity, and the cutter head assembly 2 is inserted into the mounting cavity and connected to the rotating member 11. In this embodiment, the rotating member 11 is preferably a rivet post, which is inserted vertically into the handle base 1 and fixedly connected to it. The rivet post passes through the mounting cavity, and the cutter head assembly 2 is rotatably sleeved on the rivet post. Thus, the connection between the cutter head assembly 2 and the handle base 1 via the rivet post is relatively stable, and allows for a rotatable connection between the cutter head assembly 2 and the handle base 1. Furthermore, when repairing or replacing the cutter head assembly 2, tools can be used to remove the rivet post, and then the cutter head assembly 2 can be removed, followed by the installation of a normal cutter head assembly 2 and a new rivet post. In another embodiment, the rotating member 11 is a pin; in yet another embodiment, the rotating member 11 is a universal ball joint, and the cutter head assembly 2 has a matching ball groove.

[0029] Reference Figures 2 to 4 The shaving head assembly 2 includes a shaving head body 21, a shaving head connecting frame 22, a support tongue 23, and an elastic element 24. A shaving blade is mounted on the shaving head body 21, which is adapted to drive the shaving blade to shave in close contact with the face. The shaving head body 21 is rotatably connected to the connecting frame in the vertical direction. The shaving head connecting frame 22 is rotatably connected to a rivet post, and can drive the shaving head body 21 to move back and forth or swing left and right relative to the handle base 1, thereby allowing the shaving head body 21 to rotate flexibly in multiple directions and to better fit the face. The support tongue 23 is slidably connected to the shaving head connecting frame 22, and the elastic element 24 is mounted on the shaving head connecting frame 22 and connected to the support tongue 23; the elastic element 24 is adapted to drive the support tongue 23 to abut against the shaving head body 21, providing damping force for the vertical rotation of the shaving head body 21 and a restoring force after rotation.

[0030] Reference Figures 2 to 4Specifically, the blade head connecting bracket 22 has an oblong hole 221 extending in the front-to-back direction, and a rivet post is inserted into the oblong hole 221. The blade head connecting bracket 22 can move back and forth relative to the handle base 1 with the cooperation of the oblong hole 221 and the rivet post. During shaving, the back-to-back movement of the blade head body 21 can have a buffering effect, automatically releasing some force and reducing the risk of cuts. In addition, the cooperation of the rivet post and the oblong hole 221 enables the blade head body 21 to swing left and right and move back and forth; and the reset member 12 can reset the left and right swing and back and forth movement of the blade head body 21. The structure is simple and the cost is low.

[0031] The front end of the cutter head connector 22 has integrally formed rotating protrusions 222 on both the left and right sides. Two rotating slots 211 are symmetrically formed on the cutter head body 21 along the left-right direction. The two rotating protrusions 222 are respectively inserted into the two rotating slots 211, allowing the cutter head plate to rotate relative to the cutter head connector 14 and the handle base 1 in the up-down direction. To facilitate the installation of the rotating protrusions 222 into the rotating slots 211, each rotating protrusion 222 has a transition slope. During installation, the transition slope abuts against the outer edge of the rotating slot 211, and then pressing the cutter head body 21 firmly will insert the rotating protrusion 222 into the rotating slot 211.

[0032] Reference Figures 2 to 5 The cutter head connecting frame 22 has an assembly groove at its rear end. The side wall of the support tongue 23 is integrally formed with a support lug 231. Both the support tongue 23 and the support lug 231 are slidably inserted into the assembly groove. The front end of the cutter head connecting frame 22 has a telescopic opening that communicates with the assembly groove. The telescopic opening only allows the support tongue 23 to pass through. Thus, the support lug 231 acts as a barrier, preventing the support tongue 23 from detaching from the assembly groove through the telescopic opening. In this embodiment, the elastic element 24 is preferably a drive spring. The rear end of the support tongue 23 has an integrally formed first insertion post, and the groove wall of the assembly groove has a second insertion post. The two ends of the drive spring are respectively sleeved on the first and second insertion posts, making the drive spring relatively stable after installation. The drive spring causes the support tongue 23 to protrude from the telescopic opening into a cantilevered state and abut against the cutter head body 21.

[0033] Reference Figures 3 to 5 The shaving head body 21 is tilted downwards under the action of the support tongue 23 and the elastic element 24, thus maintaining an inclined angle with the handle base 1, which is more in line with the ergonomics of shaving. During shaving, the shaving head body 21 can rotate upwards as needed. During this process, the cooperation of the support tongue 23 and the elastic element 24 can generate a damping force on the up and down rotation of the shaving head body 21, limiting the degree of freedom of the shaving head body 21 during rotation, preventing the shaving head body 21 from rotating too sensitively and cutting the face, and at the same time, it can drive the shaving head body 21 to automatically return to the tilted state after up and down rotation.

[0034] Two reset members 12 are provided, located on the left and right sides of the rotating member 11 respectively, to facilitate the resetting of the cutter head assembly 2 in the left and right directions respectively. The two reset members 12 have the same structure; the following description uses the installation structure of one reset member 12 as an example.

[0035] In this embodiment, the reset element 12 is preferably a spring, which has good elastic deformation and elastic bending reset capabilities. A spring groove 223 is provided on the rear end of the cutter head connecting frame 22 for inserting one end of the spring, and a spring post is integrally formed on the cavity wall of the mounting cavity for the other end of the spring. This improves the stability of the spring bending and compression when the cutter head connecting frame 22 swings left and right, ensuring the spring maintains a stable and reliable elastic reset force. In another embodiment, the reset element 12 is a hollow rubber cylinder. In yet another embodiment, the reset element 12 is a V-shaped spring piece, with corresponding grooves for installing the spring piece on both the cavity wall of the mounting cavity and the cutter head connecting frame 22. When the cutter head connecting frame 22 swings left and right, it causes elastic deformation on the corresponding elastic side. In yet another embodiment, the reset element 12 is an elastic rope, with a hanging ring fixed on the cavity wall near the tail end of the cutter head connecting frame 22. One end of the elastic rope is tied to the tail end of the cutter head connecting frame 22, and the other end is tied to the hanging ring.

[0036] Reference Figures 2 to 5 The handle base 1 has a rotating groove 13 near its front end. The rotating groove 13 is fan-shaped and communicates with the mounting cavity. A connector 14 is inserted into the rotating groove 13. The connector 14 includes an integrally formed snap-fit ​​support leg 15 and a cap 16. The cap 16 is located at the opening of the rotating groove 13 and covers the rotating groove 13, thereby improving aesthetics. Two snap-fit ​​supports 15 are symmetrically spaced at the bottom of the cap 16. The cutter head connecting frame 22 has two symmetrically spaced snap-fit ​​slots 224. The two snap-fit ​​supports 15 are snapped into the snap-fit ​​slots 224 respectively, so that the connector 14 is snapped into the cutter head connecting frame 22. In this way, when the cutter head assembly 2 needs to be repaired or replaced, the connector 14 can be removed from the cutter head connecting frame 22. When the cutter head connecting frame 22 swings left and right, it can drive the snap-fit ​​support leg 15 to swing left and right within the range of the rotating groove 13. The locking feet 15 are arranged at intervals with the groove wall of the rotating groove 13 in the front-to-back direction, so that the connector 14 has space to move back and forth synchronously with the cutter head connector 14.

[0037] The implementation principle of the multi-directional movement shaving head structure in this application embodiment is as follows: the shaving head body 21 can swing up and down relative to the handle base 1 through the cooperation of the rotating protrusion 222 and the rotating groove 211; the shaving head connecting frame 22 can swing left and right relative to the handle base 1 and move back and forth relative to the handle base 1 with the cooperation of the rivet post and the waist-shaped hole 221, so that the shaving head body 21 can achieve multi-directional movement relative to the handle base 1, and can automatically adjust the angle according to the curve of the face, reducing the requirements for the grip method when shaving, and making the shaving head body 21 fit the face more closely. The reset member 12 can automatically reset the shaving head assembly 2 after swinging left and right and moving back and forth. When shaving, the shaving head body 21 moves back and forth, and under the action of the reset member 12, it can play a buffering role, automatically releasing some force and reducing the risk of cuts.

[0038] Secondly, another embodiment of the present invention provides a manual razor, including the multi-directional moving blade head structure described in the first aspect above.
