The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0038] The utility model provides a razor head, such as Figure 1-16 As shown, the razor head comprises: a support portion and a shaving portion, wherein the shaving portion is movably arranged at the end of the support portion, the support portion can be connected to the handle of the razor, and the shaving portion can fit the human body to remove hair on the body surface; the shaving portion comprises a lower cover 2, the lower cover 2 is hinged to the end of the support portion, side covers 3 are fixedly installed on both sides of the lower cover 2, a pair of fixed knives 4 are fixedly installed between the two side covers 3, a movable knife 5 is slidably arranged between the pair of fixed knives 4, and the movable knife 5 can cooperate with the fixed knife 4 to remove hair on the body surface when the movable knife 5 moves, a connecting piece 6 is fixedly installed on the movable knife 5, a metal spring sheet 7 is fixedly installed on the inner side of the lower cover 2, and the metal spring sheet 7 can be slidably pressed on the surface of the connecting piece 6 to ensure that the movable knife 5 can stably cut left and right.

[0039] In this embodiment, the design of the razor head mainly solves the problems of low service life and easy clogging of the traditional razor head. By optimizing the structure and using new materials, the shaving effect and user experience are significantly improved. Not only is a fixed knife 4 fixedly installed between the two side covers 3, but also fixed knives 4 for protection are respectively provided above and below the outer surface of the movable knife 5, thereby forming a three-layer structure: the upper and lower layers are protective fixed knives 4, and the middle layer is the movable knife 5 for actually removing the hair on the body surface. The two fixed knives 4 are non-bonded and are two independent parts. The movable knife 5 can slide in this structure. When the movable knife 5 moves, it cooperates with the fixed knife 4 in the middle layer to effectively remove the hair on the body surface. At the same time, the upper and lower protective fixed knives 4 ensure safety and skin protection during use.

[0040] Specifically, the razor head of the present patent includes a support portion and a shaving portion, wherein the shaving portion can be movably arranged at the end of the support portion, so that the user can adjust it according to the needs. The design of the shaving portion is even more sophisticated, and it includes components such as a lower cover 2, a side cover 3, a fixed blade 4 and a movable blade 5. The lower cover 2 is hinged to the end of the support portion to ensure the flexibility of the shaving portion. The fixed blade 4 is fixedly installed between the two side covers 3, and the movable blade 5 can slide on the outer surface of the fixed blade 4, and the two cooperate to achieve the function of removing body surface hair.

[0041] More importantly, a connecting piece 6 is fixedly mounted on the movable blade 5, and a metal spring piece 7 is fixedly mounted on the inner side of the lower cover 2. This design allows the metal spring piece 7 to slide and press on the surface of the connecting piece 6, thereby ensuring the stable sliding of the movable blade 5 and improving the smoothness of shaving. This design not only solves the problem of easy clogging of the blade head of a traditional razor, but also significantly improves the service life of the razor.

[0042] In a further preferred embodiment of the present invention, the support portion comprises a Y-shaped frame 1 , and two forks of the Y-shaped frame 1 are hinged to the lower cover 2 .

[0043] In this embodiment, the support portion adopts a Y-shaped frame 1 design, and the two forks of the Y-shaped frame 1 are hinged to the lower cover 2, so that the entire shaving part can be more stably connected to the handle, while also providing greater flexibility and adaptability.

[0044] Such a design not only enhances the structural stability of the razor head, but also during use, the user can adjust the angle and position of the shaving part as needed, making the shaving process more comfortable and efficient.

[0045] In a further preferred embodiment of the utility model, two movable ears 8 are extended and formed on the lower cover 2, and the two movable ears 8 are respectively connected to the two forks of the Y-shaped frame 1 by pins 9. The two forks of the Y-shaped frame 1 are provided with torsion springs 10, and the movable ends of the two torsion springs 10 are respectively pressed on the two movable ears 8, and cooperate with the fixed knife 4 to provide the necessary elastic force to maintain the fit between the fixed knife 4 and the skin during shaving, and ensure that the fixed knife 4 automatically returns to its original position when not in use.

[0046] The elastic element (torsion spring 10) enhances the interaction between the cutter head and the skin by providing a certain elastic reaction force, thereby improving the comfort and efficiency of shaving.

[0047] In this embodiment, two movable ears 8 are extended from the lower cover 2, and the two movable ears 8 are movably pinned to the two forks of the Y-shaped frame 1 through pins 9. This design not only ensures the flexible rotation of the shaving part, but also provides a stable connection.

[0048] More cleverly, the two forks of the Y-shaped frame 1 are further provided with torsion springs 10. The movable ends of the torsion springs 10 are pressed onto the two movable ears 8. The advantage of such a design is that when the shaving part is rotated or adjusted, the torsion springs 10 can automatically return the shaving part to its initial position, thereby ensuring the continuity and stability of shaving.

[0049] In a further preferred embodiment of the utility model, an angle code with two push ears 11 is fixedly mounted on the connecting member 6, the two push ears 11 are movable through the metal spring sheet 7 and are located between the two movable ears 8, and a power component serving as a power source for driving the shaving part to remove hair is provided on the Y-shaped frame 1.

[0050] In this embodiment, an angle bracket with two push ears 11 is fixedly mounted on the connecting member 6, and the two push ears 11 are movable through the metal spring sheet 7 and are located between the two movable ears 8. This design not only enhances the stability of the connecting member 6, but also makes the movable knife 5 more stable and smooth during the sliding process.

[0051] In addition, a power assembly as a power source is also provided on the Y-shaped frame 1 for driving the shaving part to remove hair. This design enables the razor head to automatically provide power when in use, thereby greatly improving the efficiency and convenience of shaving.

[0052] In a further preferred embodiment of the utility model, the power assembly includes a power rod 12 that is fixedly installed on the Y-shaped frame 1, a reciprocating head 13 is fixedly installed on the output shaft of the power rod 12, at least one reciprocating push rod 14 is fixedly installed on the reciprocating head 13, the reciprocating push rod 14 is eccentrically installed with the reciprocating head 13, at least one reciprocating push rod 14 extends between the two pushing ears 11, and when the power rod 12 drives the reciprocating head 13 to rotate, at least one reciprocating push rod 14 is staggered with the two pushing ears 11 to push the connecting member 6 to slide.

[0053] In this embodiment, the power assembly includes a power rod 12, which is fixedly mounted on the Y-shaped frame 1, and a reciprocating head 13 is fixedly mounted on the output shaft of the power rod 12, and at least one reciprocating push rod 14 is fixedly mounted on the reciprocating head 13. These reciprocating push rods 14 are eccentrically mounted with the reciprocating head 13, ensuring that the reciprocating push rods 14 can generate effective driving force when the reciprocating head 13 rotates.

[0054] More importantly, at least one reciprocating push rod 14 extends between the two push ears 11, and at the same time, a long rod is detachably installed at the bottom end of the power rod 12, and the bottom end of the long rod can be connected to a motor (such as Figure 15-16 ). In use, the output shaft of the motor rotates to drive the long rod to rotate, and the long rod drives the power rod 12 to rotate. When the power rod 12 drives the reciprocating head 13 to rotate, the reciprocating push rod 14 will alternately cooperate with the two push ears 11, thereby pushing the connecting piece 6 and the movable knife 5 to slide, and realize the blade shearing.

[0055] In a further preferred embodiment of the utility model, an assembly opening 15 is formed on the fixed knife 4, a connecting seat 16 is provided in the assembly opening 15, at least two positioning columns 17 are extended from the connecting seat 16, at least two of the positioning columns 17 pass through the holes of the fixed knife 4 and are detachably connected to the lower cover 2, at least two of the positioning columns 17 are respectively located on both sides of the connecting member 6, and do not conflict with the sliding trajectory of the connecting member 6 and the movable knife 5.

[0056] In this embodiment, the fixed knife 4 is formed with an assembly opening 15, and a connection seat 16 is provided in the assembly opening 15. At least two positioning posts 17 are extended from the connection seat 16, and these positioning posts 17 all penetrate the holes of the fixed knife 4 and are detachably connected to the lower cover 2.

[0057] This design not only enhances the connection stability between the fixed knife 4 and the lower cover 2, but also makes the installation and removal of the fixed knife 4 more convenient. In addition, the design of the positioning column 17 also ensures that the movable knife 5 can maintain a stable trajectory during the sliding process, thereby avoiding conflict with the sliding trajectory of the connecting member 6 and the movable knife 5.

[0058] In a further preferred embodiment of the present invention, a shielding plate 18 is disposed in the assembly opening 15 , and the shielding plate 18 is replaceably fixed to the surface of the connecting seat 16 .

[0059] In this embodiment, the shielding plate 18 is added, which not only improves the aesthetics of the razor head, but also protects the user's body surface. More importantly, it prevents foreign matter from entering the assembly port 15, thereby protecting the delicate structure inside the head and extending the service life of the razor. The shielding plate 18 is replaceable, and the user can DIY it by himself, and can add shielding plates with different functions for replacement.

[0060] In a further preferred embodiment of the present invention, the support portion further comprises a connecting seat 19 fixedly mounted on the Y-shaped frame 1, and at least two mounting legs 20 for connecting to the handle of the shaver are fixedly mounted on the connecting seat 19.

[0061] In this embodiment, a connecting seat 19 is fixedly mounted on the Y-shaped frame 1. The design of this connecting seat 19 is very clever. It is not only a connecting component, but also a guarantee for the stable connection between the entire cutter head and the handle.

[0062] At least two mounting legs 20 are fixedly mounted on the connection seat 19, and the role of these mounting legs 20 is very critical. They can be connected with the handle of the razor to ensure the close fit between the cutter head and the handle, thereby achieving the stability and integrity of the entire razor structure.

[0063] In a further preferred embodiment of the present invention, the tooth spacing between the teeth of the fixed knife 4 is less than 0.5 mm, and the fixed knife 4 has a lower curve for convenient removal of stubble.

[0064] In this embodiment, the tooth pitch of most knives on the market is 0.55mm, which is relatively large. The tooth pitch between the teeth of the fixed knife in this scheme is about 0.06-0.48mm, which makes the trimming cleaner. The lower curve design of the fixed knife is convenient for removing stubble, and stubble is not easy to accumulate, which is convenient for cleaning.

[0065] In a further preferred embodiment of the utility model, a lubrication groove is formed on the surface of the connecting member 6, guide openings adapted to the lubrication groove are opened on both sides of the metal spring sheet 7, and avoidance openings for the two pushing ears 11 to slide are also opened on the metal spring sheet 7.

[0066] In this embodiment, a lubrication groove is formed on the surface of the connecting member 6. This design enables the connecting member 6 to maintain a stable direction and trajectory during the sliding process, thereby improving the accuracy and stability of shaving.

[0067] At the same time, guide openings adapted to the lubrication grooves are provided on both sides of the metal spring 7, and this design enables the metal spring 7 to closely match the lubrication grooves on the connecting piece 6. In addition, avoidance openings for the two push ears 11 to slide are also provided on the metal spring 7. This design not only provides sufficient sliding space for the push ears 11, but also avoids friction and interference between the metal spring 7 and the push ears 11, thereby ensuring stability and smoothness during shaving.

[0068] To sum up, compared with the relevant technology, the present solution as a whole solves the problems of low service life and easy clogging of the traditional razor head, especially the use of metal spring 7 and connecting part 6, which ensures the stable sliding of the movable blade 5, while improving the smoothness of shaving, and the smaller tooth spacing makes trimming smoother. The torsion spring 10 as the elastic element enhances the interaction between the blade head and the skin by providing a certain elastic reaction force, thereby improving the comfort and efficiency of shaving.
