Description

Technical Field

[0001] This invention relates to the field of hair cutting equipment technology, and more specifically to a shaving razor device with a double-bar swing connection mechanism. Background Technology

[0002] In existing technologies, the connection between the shaver head and the support generally adopts a single pendulum rod connection structure. This connection structure only sets a pendulum rod on one side of the support to connect the shaver head, resulting in uneven force distribution. When the shaver head swings, it is easy to deviate, failing to fully conform to the contours of the skin. This can easily lead to incomplete shaving, pulling of hair, or even excessive pressure on one side causing skin abrasions. At the same time, the force is concentrated at the connection point of the single pendulum rod structure, which is prone to wear and loosening after long-term use, affecting the lifespan of the device. Some shavers also use a floating shaver head structure, but the floating structure is mostly single-axis, which can only achieve swinging in one direction. It cannot adapt to the complex curved contours of different parts of the body, and the skin-fitting effect is still not ideal. Summary of the Invention

[0003] In view of this, the present invention provides a razor device with a double-bar swing connection mechanism.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A razor device with a double-bar swing connection mechanism includes a device body and a razor head assembly. A double-bar swing connection mechanism is provided between the device body and the razor head assembly to connect the two. The double-bar swing connection mechanism includes a bracket mounted on the device body and double swing rod structures mounted on both sides of the bracket. Viewed from the orthographic projection direction of the two ends of the razor head assembly, at least two first hinge points are formed between one end of the double swing rod structure and the razor head assembly, and the two first hinge points are spaced apart along both sides of the center line of the razor head assembly. At least one second hinge point is formed between the other end of the double swing rod structure and the bracket, so that the razor head assembly can rotate and swing relative to the device body at the second hinge point under the action of external force to automatically adjust the angle to fit the skin.

[0006] Preferably, each double-rocker structure includes two spaced-apart rockers, with the ends of the two rockers connected to a cutter head assembly and a bracket, respectively. Each rocker has a corresponding first hinge point and a second hinge point. A shaft structure is provided between each rocker and the bracket and the cutter head assembly. The shaft structure passes through the corresponding first hinge point and second hinge point, allowing the rocker to move relative to the bracket or the cutter head assembly, and is oscillatingly connected to the bracket and the cutter head assembly through the shaft structure.

[0007] Preferably, both of the swing arms have a support end connected to the bracket and a cutter head connection end connected to the cutter head assembly. The first hinge point and the second hinge point are respectively located at the center of the support end and the cutter head connection end. A first center distance a1 is formed between the centers of the two support ends. The two cutter head connection ends have corresponding centers, and a second center distance a2 is formed between the centers of the two cutter head connection ends.

[0008] Preferably, the first center distance a1 is equal to the second center distance a2, or the first center distance a1 is greater than the second center distance a2, or the first center distance a1 is less than the second center distance a2.

[0009] Preferably, the bracket has a connecting rod connection portion connected to the double swing arm structure, a main body connection portion connected to the main body of the device, and a bracket support portion disposed between the main body connection portion and the connecting rod connection portion. The connecting rod connection portion is formed by bending one end of the bracket support portion away from the main body connection portion toward the cutter head assembly.

[0010] Preferably, the support portion of the bracket includes a main rod portion and a connecting rod portion. The main rod portion is connected to the main body connecting portion, and the connecting rod portion is disposed on the side of the support portion near the connecting rod connecting portion. The width of the side of the connecting rod portion connected to the connecting rod connecting portion gradually decreases towards the main rod portion until it is consistent with the width of the main rod portion.

[0011] Preferably, the support portion of the bracket is inclined or bent from the main body connecting portion toward the connecting rod portion.

[0012] Preferably, an elastic element is provided between the cutter head assembly and the double-bar swing connection mechanism. The elastic element is located on both sides or at the center of the cutter head assembly, and its two ends are respectively connected to the double-bar swing connection mechanism and the cutter head assembly.

[0013] Preferably, the elastic element is a torsion spring disposed on both sides of the bracket, the torsion spring is sleeved on the shaft structure, and the two ends of the torsion spring respectively abut against the cutter head assembly and the two swing rods.

[0014] Preferably, the end face of the cutter head assembly that connects with the rocker arm forms a rocker groove, and the side wall of the rocker groove near the center of the cutter head assembly is partially sunken to form a torsion spring limiting groove. The torsion spring is sleeved on the shaft structure and then embedded in the torsion spring limiting groove. One end of the torsion spring abuts against the groove wall of the torsion spring limiting groove. One of the two rocker arms has a torsion spring retaining groove, and the other end of the torsion spring extends into the torsion spring retaining groove and is limited to the rocker arm.

[0015] Preferably, when viewed from both sides along the length of the cutter head assembly, the two swing arms at least partially overlap with the connecting portion of the support rod.

[0016] The beneficial effects of this invention are as follows: by setting a double-bar swing connection mechanism consisting of a bracket and double-bar swing arms on both sides between the main body of the device and the blade assembly, the blade assembly can synchronously and adaptively swing and adjust its angle according to the undulations of the skin surface. Compared with the single-bar structure, the force on both sides is more even, the blade head has better skin contact, and there will be no problem of excessive local pressure scratching the skin or insufficient pressure causing incomplete shaving during the shaving process. At the same time, the double-bar connection structure can also improve the structural strength of the connection position and extend the overall service life of the device.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] The present invention will now be further described with reference to the accompanying drawings.

[0029] This invention provides the following technical solution:

[0030] As attached Figure 1-9 As shown, this invention discloses a shaver device with a double-bar swing connection mechanism, including a device body 1 and a shaver head assembly 2. A double-bar swing connection mechanism 3 is provided between the device body 1 and the shaver head assembly 2 for connecting the two. The double-bar swing connection mechanism 3 includes a bracket 4 disposed on the device body 1 and double swing rod structures 5 disposed on both sides of the bracket 4. Viewed from the orthographic projection direction of the two ends of the shaver head assembly 2, at least two first hinge points 51 are formed between one end of the double swing rod structure 5 and the shaver head assembly 2. The two first hinge points 51 are arranged at intervals along both sides of the center line of the shaver head assembly 2. At least one second hinge point 52 is formed between the other end of the double swing rod structure 5 and the bracket 4, so that the shaver head assembly 2 can rotate and swing relative to the device body at the second hinge point under the action of external force to automatically adjust the angle to fit the skin. Specifically, in this design, by setting a double-swing arm structure on both sides of the bracket to connect the blade head assembly, the force on the blade head assembly can be evenly distributed at the connection position. During the swinging process, the blade head will not deviate and can always maintain a good fit with the skin. This avoids excessive pressure on one side during shaving, which may scratch the skin, or insufficient pressure on one side, which may result in incomplete shaving. At the same time, the double-swing arm distributes the force, which can also reduce wear at the connection point and extend the overall service life of the device. The distribution of the two hinge points also allows the blade head to adapt to the complex curved contours of the skin and adaptively adjust the fitting angle, resulting in a better skin-fitting floating effect.

[0031] Reference Appendix Figure 2-8Each dual-swing arm structure 5 includes two spaced-apart swing arms 6. The two ends of the two swing arms 6 are respectively connected to the blade assembly 2 and the support 4. Each swing arm 6 has a corresponding first hinge point 51 and a second hinge point 52. A shaft structure 7 is provided between each swing arm 6 and the support 4 and the blade assembly 2. The shaft structure 7 passes through the corresponding first hinge point 51 and second hinge point 52, allowing the swing arm 6 to move relative to the support 4 or the blade assembly 2, and to swing and connect with the support 4 and the blade assembly 2 via the shaft structure 7. Specifically, in this embodiment, each swing arm can swing independently via the shaft structure. When the blade assembly conforms to different undulating skin surfaces, each swing arm can adaptively swing with the angle change of the blade head, further improving the blade head's adaptability to complex curved surfaces and ensuring that all areas of the blade head conform evenly to the skin.

[0032] The distance L from the two first hinge points 51 to the centerline of the blade assembly 2 is 1mm ≤ L ≤ 40mm. Specifically, in this embodiment, the spacing of the first hinge points 51 is controlled within this range. This ensures that the force distribution on both sides of the blade assembly is sufficiently uniform, preventing skew during blade swing, while also preventing an increase in the overall structural volume of the device due to excessive spacing, thus adapting to the conventional size design requirements of shaver devices. In specific implementation, the specific value of L can be adjusted according to the overall length of the blade assembly to meet the design requirements of different product specifications.

[0033] Furthermore, both swing arms 6 have a support end 9 connected to the bracket 4 and a blade connection end 8 connected to the blade assembly 2. The first hinge point 51 and the second hinge point 52 are respectively located at the center of the support end 9 and the blade connection end 8. A first center distance a1 is formed between the centers of the two support ends 9, and a second center distance a2 is formed between the centers of the two blade connection ends 8. Specifically, in this embodiment, by adjusting the size matching relationship between the first center distance a1 and the second center distance a2, the operational stability of the parallelogram linkage mechanism is further optimized: when a1 and a2 are equal, the motion trajectory of the parallelogram linkage mechanism always remains parallel, and the blade assembly will not tilt or deviate during adaptive swinging, resulting in higher skin-fitting accuracy; at the same time, the design of matching the two swing arms with equal lengths allows the force on the blade assembly to be evenly transmitted to the connection position of the two swing arms when subjected to skin pressure, avoiding wear and loosening of the single-sided shaft structure under long-term stress, and further improving structural reliability and service life.

[0034] In one embodiment, the first center distance a1 is greater than the second center distance a2. Specifically, in this embodiment, when the first center distance a1 is greater than the second center distance a2, the tips of the teeth will rise as the blade head extends backward. At this time, the angle of the blade head against the skin will better conform to the concave parts of the human body contour, such as the armpit and neck curve, which can better follow the curvature of the skin, improve the cleanliness of shaving, and at the same time avoid the tips of the teeth pressing excessively against the skin, reducing the risk of scratches and meeting the shaving needs of different parts of the body.

[0035] In another embodiment, the first center distance a1 is smaller than the second center distance a2. Specifically, in this embodiment, when the first center distance a1 is smaller than the second center distance a2, the tip of the teeth will tilt downwards as the blade head extends backwards. At this time, the angle of the blade head against the skin will better fit the protruding parts of the human body contour, such as the outer side of the arm or the shinbone of the lower leg. This allows the blade head to always stay in contact with the protruding skin surface, preventing missed shavings due to angle issues and improving the smooth shaving effect. Users can choose products with corresponding parameters according to their commonly used shaving areas and usage habits to adapt to different usage needs.

[0036] Reference Appendix Figure 2 The bracket 4 has a connecting rod connection part 10 connected to the double swing rod structure 5, a main body connection part 11 connected to the device body 1, and a bracket support part 12 disposed between the main body connection part 11 and the connecting rod connection part 10. The connecting rod connection part 10 is formed by bending one end of the bracket support part 12 away from the main body connection part 11 toward the cutter head assembly 2. Specifically, in this embodiment, the connecting rod connection part 10 is rotatably connected to the double swing rod structure 5 through a rotating shaft 7, the main body connection part 11 is fixedly connected to the device body 1 through bolts 8, and the bracket support part 12 has an arc-shaped structure with its two ends integrally formed with the main body connection part 11 and the connecting rod connection part 10, respectively. When the cutter head assembly 2 is subjected to an external force, the double rocker arm structure 5 rotates around its hinge point 6 with the main body 1 of the device, and drives the support part 12 to produce a slight deformation through the connecting rod connection part 10. This deformation causes the support part 12 to apply a reverse force to the main body connection part 11, and then transmits the force to the main body 1 of the device through the main body connection part 11, so as to achieve stable support and guidance for the movement trajectory of the cutter head assembly 2.

[0037] Furthermore, the bracket support portion 12 includes a main rod portion 13 and a connecting rod portion 14. The main rod portion 13 is connected to the main body connecting portion 11. The connecting rod portion 14 is disposed on the side of the bracket support portion 12 near the connecting rod connecting portion 10. The width of the side of the connecting rod portion 14 connected to the connecting rod connecting portion 10 gradually decreases towards the main rod portion 13 until it is consistent with the width of the main rod portion 13. Specifically, in this embodiment, the main rod 13 is an elongated structure extending along the main connecting part 11, with uniform width and thickness to ensure stable support for the overall structure; one end of the connecting rod 14 is fixedly connected to the connecting rod 10, and the other end is smoothly connected to the main rod 13. As its width gradually decreases towards the main rod 13, the connection between the connecting rod 14 and the main rod 13 forms a natural tapered transition. This structural design can effectively disperse stress concentration at the connection point, improve the overall structural strength and load-bearing capacity of the support part 12, and avoid weak points that may occur due to structural abrupt changes, thus ensuring the structural stability and reliability of the support part 12 during long-term use.

[0038] Reference Appendix Figure 6 The bracket support portion 12 is inclined or bent from the main body connecting portion 11 toward the connecting rod portion 10. Specifically, in this embodiment, the bracket support portion 12 is inclined from the main body connecting portion 11 toward the connecting rod portion 10, so that a certain inclination angle is formed between the bracket support portion 12 and the main body connecting portion 11. This inclination angle can ensure that the force transmission path is more direct when the bracket support portion 12 supports external components, thereby improving the support stability of the overall structure; at the same time, this inclination setting can also reduce the bending deformation of the bracket support portion 12 under external pressure, and enhance the structural strength of the bracket support portion 12.

[0039] Furthermore, an elastic element 15 is provided between the blade assembly 2 and the double-bar swing connection mechanism 3. The elastic element 15 is located on both sides or at the center of the blade assembly 2, and its two ends are respectively connected to the double-bar swing connection mechanism 3 and the blade assembly 2. Specifically, in this embodiment, by providing the elastic element, the blade assembly can be provided with an adaptive rebound force. When the undulations on the skin surface disappear, the elastic element can quickly drive the blade assembly to return to its initial position, always maintaining a suitable pressure of the blade assembly on the skin. This prevents scratching the skin due to excessive pressure and avoids missing hairs due to insufficient pressure, further improving the shaving experience. When the elastic element is located at the center of the blade assembly, the force on the blade assembly is more even, the structure is simpler, and it is convenient for the overall miniaturization design of the device. When the elastic element is located on both sides of the blade assembly, it can provide independent rebound force to the two swing rods respectively, the distribution of rebound force is more balanced, and the response speed of swing adjustment is faster.

[0040] Reference Appendix Figure 2Alternatively, in embodiment 6, the elastic element 15 is a torsion spring disposed on both sides of the support 4, the torsion spring being sleeved on the shaft structure 7, and the two ends of the torsion spring respectively abutting against the cutter head assembly 2 and one of the two swing rods 6. Specifically, in this embodiment, when the cutter head assembly 2 is subjected to an external force and swings relative to the support 4, the shaft structure 7 will rotate synchronously with the cutter head assembly 2. At this time, the torsion spring sleeved on the shaft structure 7 will undergo elastic deformation due to the rotation of the shaft structure 7, and its two ends will apply opposite elastic forces to the cutter head assembly 2 and the swing rod 6 respectively. This elastic force enables the cutter head assembly 2 to quickly return to its initial position after the external force is removed, thereby ensuring that the cutter head assembly 2 always maintains a stable working posture and improving the reliability and stability of the equipment operation.

[0041] Reference Appendix Figure 6 The end face of the cutter head assembly 2 that connects with the rocker arm 6 is recessed to form a rocker groove 16. The side wall of the rocker groove 16 near the center of the cutter head assembly 2 is partially recessed to form a torsion spring limiting groove 17. The torsion spring is sleeved on the shaft structure 7 and then embedded in the torsion spring limiting groove 17. One end of the torsion spring abuts against the groove wall of the torsion spring limiting groove 17. One of the two rocker arms 6 has a torsion spring retaining groove 18. The other end of the torsion spring extends into the torsion spring retaining groove 18 and is limited to the rocker arm 6. Specifically, in this embodiment, the groove wall of the torsion spring limiting groove 17 forms a fixed support for one end of the torsion spring. When the rocker arm 6 swings around the shaft structure 7, the other end of the torsion spring is subjected to force in the torsion spring retaining groove 18, causing the torsion spring to undergo elastic deformation and accumulate restoring force. This restoring force reacts to the rocker arm 6 through the torsion spring retaining groove 18, thereby enabling the rocker arm 6 to drive the cutter head assembly 2 to swing and reset stably relative to the shaft structure 7, ensuring that the cutter head assembly 2 always maintains reliable contact with the workpiece during operation, and improving machining accuracy and stability.

[0042] Reference Appendix Figure 4 Viewed from both sides along the length of the cutter head assembly 2, the two rocker arms 6 coincide with at least partially with the connecting rod 10 of the bracket 4. In order for the shaft structure 15 to position the rocker arms 6, the shaft structure 15 passes through the overlapping area of ​​the rocker arms 6 and the connecting rod 10 to achieve precise positioning. The rocker arms 6 form a rotational engagement with the connecting rod 10 through the shaft structure 15. Under the restriction of the shaft structure 15, the rocker arms 6 can only rotate around the shaft structure 15 at a preset angle. This rotation range ensures that the rocker arms 6 will not be excessively displaced during the movement, thereby avoiding the rocker arms 6 from squeezing the torsion spring beyond its elastic limit, effectively preventing the torsion spring from being crushed, ensuring that the torsion spring can always provide a stable elastic restoring force, and ensuring the normal working state of the cutter head assembly 2.

[0043] In another embodiment, the double-swing bar structure 5 is Y-shaped. The two branches of the Y-shaped double-swing bar form two first hinge points 51 with the blade assembly 2, and the confluence end forms a single second hinge point 52 with the bracket 4. The overall structure is more streamlined, reducing the number of parts, lowering the assembly difficulty and overall cost of the device. At the same time, the confluence end of the Y-shaped structure has better force concentration, a shorter force transmission path, and a faster swing response speed. It can quickly adjust the blade angle when the skin contour changes to maintain fit. In addition, the Y-shaped structure itself has higher structural strength, is less prone to deformation, and has better structural stability after long-term use.

[0044] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
