Description

Technical Field

[0001] The utility model relates to the technical field of transmission mechanisms, and in particular discloses a double - cutter - head transmission mechanism of a reciprocating shaver. Background Art

[0002] The double - cutter - head transmission mechanism refers to a combination of two cutter heads for trimming different hairs into a whole, and then it is installed in a shaver. In the existing double - cutter - head transmission mechanism, the two cutter heads often swing reciprocally independently, and it must be realized by a swinging member (also called a vibrator, a vibrator, etc. in the industry) arranged on the body of the trimming tool, and the swinging member is driven by the output shaft of the motor in the body. Although the setting of the swinging member can meet the independent reciprocating swing of each cutter head in the multi - cutter - head assembly, relatively speaking, it also makes the transmission structure of the trimming tool more complex and the cost higher. At the same time, the independent reciprocating swing of each cutter head is also likely to cause a pulling feeling on the skin when the cutter is not sharp, reducing the comfort of the shaver during use. Therefore, there is an urgent need for a parallel swing motion structure of a shaver and a shaver applying this structure. Content of the Utility Model

[0003] In order to overcome the disadvantages and deficiencies existing in the prior art, the purpose of the utility model is to provide a double - cutter - head transmission mechanism of a reciprocating shaver.

[0004] To achieve the above purpose, a double - cutter - head transmission mechanism of a reciprocating shaver of the utility model includes a swing rod member and a cutter head. A plurality of blades for cooperating with an external cutter net to realize shaving are arranged in an array on the cutter head, and a protrusion condition for installing the cutter head is arranged on the swing rod member; it also includes a driving member and a first rod body for cooperating with the swing rod member. The swing rod member reciprocates and is sleeved outside the first rod body. The protrusion condition is integrally arranged with the swing rod member, and the driving member drives the swing rod member and drives the cutter head to reciprocate through the protrusion condition.

[0005] Preferably, a second cylinder is arranged on the cutter head, and a first groove for accommodating the second cylinder is arranged on the protrusion condition. The second cylinder abuts against the inner wall of the first groove and drives the cutter head to move through the protrusion condition. The stable setting of the second cylinder in the first groove enhances the connection strength between the cutter head and the protrusion condition and facilitates the replacement of the cutter head at the same time, reducing the possibility of the cutter head loosening or falling off due to vibration or impact, improving the overall stability and durability of the shaver. Through the simple cooperation of the cylinder and the groove, complex transmission and connection functions are realized, not only reducing the production cost, but also simplifying the assembly and maintenance process, improving the production efficiency and the use convenience of users.

[0006] Preferably, a first block is further provided on the rocker member, a first rod is slidably provided on the first block, and the first rod is used to be mounted on an external shaver. The sliding design of the first rod on the first block provides a guide for the linear movement of the rocker member, and by accurately controlling the sliding trajectory of the first rod, it can be ensured that the rocker member maintains a linear and stable operation during the shaving process. The linear and stable operation can reduce the deviation and shaking of the cutter head during the shaving process, thereby improving the accuracy and effect of shaving. The firm connection between the first rod and the external shaver provides stable transmission support for the rocker member.

[0007] Preferably, the rocker member, the protrusion and the first block are produced by one-piece injection molding. The one-piece injection molding technology combines multiple components into a whole for production, reducing the assembly steps and conversion time in the production process. This production method can significantly improve production efficiency, shorten the production cycle, and reduce production costs. Since all components are molded simultaneously during the injection molding process, their precise matching and connection strength are ensured, thereby improving the overall stability and durability of the product. This production method can optimize the transmission and connection performance of the product and improve the overall performance and user experience of the shaver.

[0008] Preferably, the double-blade head transmission mechanism also includes a plate body, a groove for accommodating the movement space of the protruding condition is provided on the plate body, an elastic member is arranged in the groove, and the elastic member is used to connect the plate body and the protruding condition. The plate body provides stable support for the entire transmission mechanism, ensuring that the various components can work together and ensure the stability and reliability of the transmission. The design of the groove provides sufficient movement space for the protruding condition, so that the blade head can move according to a predetermined trajectory to achieve an efficient shaving effect. The elastic member plays a key role in buffering and elasticity during the transmission process. It can reduce the impact and vibration caused by the transmission and improve the comfort and safety of shaving.

[0009] Preferably, a second block is provided on the plate body, and a third groove is provided on the second block for accommodating the end of the first rod body. Two second blocks are provided, and the two second blocks are provided at both ends of the first rod body to fix / limit the first rod body. The two ends of the first rod body are respectively accommodated by the third grooves on the two second blocks, thereby achieving fixation and limitation of the first rod body. This design ensures the stability and accuracy of the first rod body during the transmission process, and avoids transmission failure or damage caused by shaking or deviation.

[0010] Preferably, a lubricating layer is provided between the first block and the first rod body, and the lubricating layer can significantly reduce the friction coefficient between the two, thereby reducing friction and wear.

[0011] Preferably, a disc is provided at the output end of the driving member. A first cylinder protrudes from the disc. The axis of the first cylinder does not coincide with the rotation axis of the disc. The disc is driven by the driving member to drive the first cylinder to rotate. A second groove for accommodating the first cylinder is formed on the swing rod member. The first cylinder drives the swing rod member to reciprocate by abutting against the inner wall of the second groove. By driving the disc to rotate via the driving member, the first cylinder moves along its circular trajectory. When the first cylinder abuts against the inner wall of the second groove, a driving force is generated, which causes the swing rod member to move during the reciprocating motion, realizing the reciprocating motion of the swing rod member, thereby supporting the reciprocating cutting action of the razor during shaving.

[0012] Preferably, a tool holder is provided on the cutter head. The tool holder is used for slidably arranging on the external housing. The tool holder serves as the contact point between the cutter head and the external housing. By slidably arranging on the external housing, it provides stable guidance for the reciprocating motion of the cutter head. This design can ensure the stability and accuracy of the cutter head during the reciprocating motion, avoiding poor shaving effect or damage to the cutter head caused by shaking or deviation. At the same time, the tool holder not only provides sliding support for the cutter head but also enhances the structural stability between the cutter head and the external housing, reducing the risk of cutter head deformation or detachment caused by external forces, improving the overall stability and service life of the razor.

[0013] Preferably, the length of the second groove is not less than the rotation diameter length of the cylinder.

[0014] The beneficial effects of the present utility model: Through the stable drive of the driving member and the reciprocating motion of the cutter head, the beard can be shaved quickly and thoroughly, saving valuable time for the user. Due to the close cooperation and stable transmission between the cutter head and components such as the driving member and the swing rod member, wear and faults can be reduced, thereby extending the service life of the razor. By optimizing the design of the transmission mechanism, the cutter head on the swing rod member is directly driven by the driving member to reciprocate, reducing the production cost while improving the shaving efficiency, avoiding the skin pulling feeling caused by the opposite motion of multiple cutter heads, and improving the user experience.

[0025] For the convenience of understanding by those skilled in the art, the present utility model will be further described below in conjunction with embodiments and the accompanying drawings. The content mentioned in the embodiments does not limit the present utility model.

[0026] Please refer to Figures 1 to 8 As shown, a double-cutter head transmission mechanism of a reciprocating shaver of the present utility model includes a swing rod member 1 and a cutter head 14. A plurality of blades for cooperating with an external cutter net 15 to achieve shaving are arranged in an array on the cutter head 14. A protrusion condition 2 for mounting the cutter head 14 is arranged on the swing rod member 1; it further includes a driving member 7 and a first rod body 6 for cooperating with the swing rod member 1. The swing rod member 1 reciprocates and is sleeved outside the first rod body 6. The protrusion condition 2 is integrally provided with the swing rod member 1. The driving member 7 drives the swing rod member 1 and drives the cutter head 14 to reciprocate via the protrusion condition 2. There are multiple cutter heads 14 and all the cutter heads 14 reciprocate in the same direction and simultaneously.

[0027] Specifically, through the stable driving of the driving member 7 and the reciprocating movement of the cutter head 14, beards or hairs can be shaved quickly and thoroughly, saving valuable time for users. Due to the close cooperation and stable transmission between the cutter head 14 and components such as the driving member 7 and the swing rod member 1, wear and failures can be reduced, thereby extending the service life of the shaver. By optimizing the design of the transmission mechanism, the noise and vibration during operation can be reduced, improving the user experience.

[0028] Specifically, in other embodiments, a shock-absorbing layer is further provided on the driving member 7 and the rocker member 1. In this embodiment, the noise-reducing layer is a honeycomb noise-reducing mesh. The setting of the shock-absorbing layer can effectively reduce the noise generated by the cutter head 14 during the reciprocating motion, providing the user with a quieter shaving environment. At the same time, by reducing vibration and impact, the shaving process is smoother, thereby improving the user's comfort.

[0029] Specifically, there are two protrusions 2, each of which is equipped with a cutter head 14. The driving member 7 is used to drive the two cutter heads 14 to move in the same direction. The simultaneous operation of the two cutter heads 14 is equivalent to double the working area and efficiency, and can cover a larger shaving area in a shorter time, thereby significantly improving the shaving efficiency. The same-direction movement of the two cutter heads 14 ensures that the feeling of pulling is avoided during the shaving process, and a faster shaving speed and a smoother shaving feeling can be felt, thereby enhancing the user's overall usage experience.

[0030] Specifically, a second column 18 is provided on the cutter head 14, and a first groove 3 for accommodating the second column 18 is provided on the protruding portion 2. The second column 18 contacts the inner wall of the first groove 3 and drives the cutter head 14 to move via the protruding portion 2. The stable arrangement of the second column 18 in the first groove 3 enhances the connection strength between the cutter head 14 and the protruding portion 2 and facilitates the replacement of the cutter head 14, reduces the possibility of loosening or falling off of the cutter head due to vibration or impact, and improves the overall stability and durability of the shaver. Through the simple cooperation of the column and the groove, complex transmission and connection functions are realized, which not only reduces the production cost, but also simplifies the assembly and maintenance process, improves the production efficiency and user convenience.

[0031] Specifically, a first block 5 is also provided on the rocker member 1. The first block 5 is made of wear-resistant material. The first block 5 is slidably sleeved on the outside of the first rod 6. The first rod 6 is used to be installed on the shell 16 of the external shaver so that the rocker member 1 can reciprocate along the first rod 6. The sliding design of the first rod 6 on the first block 5 provides a guide for the linear movement of the rocker member 1. By accurately controlling the sliding trajectory of the first rod 6, it can be ensured that the rocker member 1 maintains a straight and stable operation during the shaving process. The straight and stable operation can reduce the deviation and shaking of the cutter head during the shaving process, thereby improving the accuracy and effect of shaving. The firm connection between the first rod 6 and the external shaver provides a stable transmission support for the rocker member 1.

[0032] Specifically, the swing rod member 1, the protruding condition 2, and the first block 5 are integrally injection molded. The integrally injection molding technology combines multiple components into one whole for production, reducing the assembly process and conversion time during production. This production method can significantly improve production efficiency, shorten the production cycle, and reduce production costs. Since all components are molded simultaneously during the injection process, it ensures the precise matching and connection strength between them, improving the overall stability and durability of the product. This production method can optimize the transmission and connection performance of the product, enhancing the overall performance and user experience of the razor.

[0033] Specifically, the double - blade head transmission mechanism further includes a plate body 12 for covering the swing rod member 1, the first rod body 6, and the first block 5. A groove 20 for accommodating the movement space of the protruding condition 2 is formed on the plate body 12. An elastic member 13 is arranged in the groove 20. The elastic member 13 is used to connect the plate body 12 and the protruding condition 2 to seal the gap between the plate body 12 and the protruding condition 2. The plate body 12 provides stable support for the entire transmission mechanism, ensuring that each component can work together, guaranteeing the stability and reliability of the transmission. The design of the groove 20 provides sufficient movement space for the protruding condition 2, enabling the cutter head 14 to move along a predetermined trajectory to achieve an efficient shaving effect. The elastic member 13 plays a key buffering and elastic role during the transmission process. It can reduce the impact and vibration generated by the transmission, improving the comfort and safety of shaving. The elastic member 13 seals the gap between the protruding condition 2 and the groove, thus preventing the beard hairs and other debris cut by the cutter head 14 from passing through the groove and entering the product interior, which may affect the cleaning and performance.

[0034] Specifically, the plate body 12 is fixed on the housing 16 of the razor. A second block 10 is arranged below the plate body 12. A third groove 11 for accommodating the end of the first rod body 6 is provided on the second block 10. There are two second blocks 10, and the two second blocks 10 are arranged at both ends of the first rod body 6 to fix / limit the first rod body 6. By respectively accommodating the two ends of the first rod body 6 in the third grooves 11 on the two second blocks 10, the fixation and limitation of the first rod body 6 are achieved. This design ensures the stability and accuracy of the first rod body 6 during the transmission process, avoiding transmission failure or damage caused by shaking or deviation.

[0035] Specifically, the first block 5 is made of copper or copper alloy. A lubricating layer is provided between the first block 5 and the first rod body 6. The lubricating layer can significantly reduce the friction coefficient between the two, thereby reducing friction and wear.

[0036] Specifically, the lubricating layer can also be lubricating oil, such as mineral oil, synthetic oil, etc.; lubricating grease, which has a higher viscosity and adhesion and can form a durable lubricating film; polytetrafluoroethylene (PTFE) coating. In this embodiment, the lubricating layer is a copper sleeve.

[0037] Specifically, a disk 8 is provided at the output end of the driving member 7. An eccentric first cylinder 9 protrudes from the disk 8. The axis of the first cylinder 9 does not coincide with the rotation axis of the disk 8. The disk 8 is driven by the driving member 7 to drive the first cylinder 9 to rotate;

[0038] A second groove 4 for accommodating the first cylinder 9 is formed in the swing rod member 1. The first cylinder 9 drives the swing rod member 1 to reciprocate by abutting against the inner wall of the second groove 4. By driving the disk 8 to rotate through the driving member 7, the first cylinder 9 moves along its circular trajectory. When the first cylinder 9 abuts against the inner wall of the second groove 4, a driving force is generated, and this driving force causes the swing rod member 1 to move during reciprocation, realizing the reciprocating motion of the swing rod member 1, thereby supporting the reciprocating cutting action of the razor during shaving.

[0039] Specifically, the opening direction of the second groove 4 is perpendicular to the length direction of the first rod 6.

[0040] Specifically, the length of the second groove 4 opened ≥ the rotation diameter length of the first cylinder 9.

[0041] Specifically, the housing 16 is provided with a knife holder 19. The cutter head 14 is movably arranged in the knife holder 19. The cutter net 15 is arranged on the knife holder 19 and is used to cover the cutter head 14 and the blade. A plurality of blades on the cutter head 14 are arranged in parallel and collinearly.

[0042] Specifically, a protrusion 21 is provided on the cutter head 14. The protrusion 21 is used for slidably arranging on the external housing 16. The protrusion 21 serves as the contact point between the cutter head 14 and the external housing 16. By slidably arranging on the external housing 16, it provides stable guidance for the reciprocating motion of the cutter head 14. This design can ensure the stability and accuracy of the cutter head 14 during reciprocating motion, avoiding poor shaving effects or damage to the cutter head caused by shaking or deviation. At the same time, the protrusion not only provides sliding support for the cutter head 14, but also enhances the structural stability between the cutter head 14 and the external housing 16, and can reduce the risk of deformation or detachment of the cutter head 14 caused by external forces, improving the overall stability and service life of the razor.

[0043] Specifically, the moving direction of the cutter head 14 is the same as the length direction of the first rod 6.

[0044] Specifically, in other embodiments, the driving member 7 can also adopt a linear drive motor.

[0045] Specifically, the double-cutter head transmission mechanism further includes a lithium battery for supplying power to the driving member 7.

[0046] Specifically, fourth grooves 17 are formed on both the plate body 12 and the second block 10. The fourth grooves 17 are threaded holes for externally connecting the plate body 12 and the second block 10 via bolts.
