Description

Technical Field

[0001] This utility model relates to the technical field of razor head structure, and in particular to a razor head structure. Background Technology

[0002] Currently, with social development, people have more social occasions in their daily work, so men who need to socialize pay special attention to their facial appearance, especially in terms of beard trimming. Therefore, to facilitate men's beard trimming and fine-tuning, a trimming blade is installed on the back of the razor handle, which can easily shave beards in curved areas such as sideburns or under the nose. However, in the existing technology, the multi-layer razor blades are first inserted into the front of the handle, and then the handle is flipped to install the trimming blades on the back. However, when the handle is flipped, the multi-layer razor blades are not fixed, so the blades are very easy to detach from the slots on the handle, making the assembly very difficult. Furthermore, the blades of the multi-layer razor blades may come into hard contact with the assembly platform and be damaged, resulting in a low product qualification rate after assembly. Therefore, further improvements are needed. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art are within the protection scope of the present utility model.

[0031] Example 1: like Figures 1-8 As shown in the figure, the razor head structure described in this embodiment includes a razor holder 1, a trimming blade 100, and a multi-layer razor blade 3. The razor holder 1 is made of plastic. A first mounting position 14 and a second mounting position 15 are formed on the front side of the razor holder 1. The multi-layer razor blade 3 is mounted in the first mounting position 14, with the cutting edge 103 of each razor blade 3 facing the front side of the razor holder 1 and exposed. The trimming blade 100 is mounted in the second mounting position 15, with the cutting edge 103 of the trimming blade 100 facing the rear side of the razor holder 1 and exposed. This allows the trimming blade 100 and the multi-layer razor blade 3 to be mounted in the first mounting position 14 and the second mounting position 15 respectively with only the front side of the razor holder 1 facing upwards, thus eliminating the need for flipping during the installation of the trimming blade 100 and the multi-layer razor blade 3, improving assembly efficiency. Both the trimming blade 100 and the multi-layer razor blade 3 are made of steel.

[0032] In this embodiment, a mounting component 200 is also required for the installation of the finishing blade 100. The mounting component 200 is also made of plastic. A recess 151 and a support platform 152 are formed on the second mounting position 15 along the first direction of the tool holder 1. The support platform 152 is located behind the recess 151. The side of the support platform 152 located inside the recess 151 is a first support surface 153. The cutting edge 103 of the finishing blade 100 is mounted on the first support surface 153 with its blade facing the rear of the tool holder 1. The mounting member 200 is inserted into recess 151 to press the finishing blade 100, so that the finishing blade 100 is fixed in recess 151; specifically, the finishing blade 100 includes a first blade body portion 101 and a second blade body portion 102 arranged along the first direction of the tool holder 1, the second blade body portion 102 is bent relative to the first blade body portion 101, and a cutting edge 103 is formed on one side of the second blade body portion 102 arranged along the first direction of the tool holder 1, the cutting edge 103 extending obliquely toward the rear side of the tool holder 1; The included angles between the first blade portion 101 and the second blade portion 102, and between the first inner wall 201 and the second inner wall 202 of the mounting member 200, are both obtuse angles. The first blade portion 101 is clamped between the first inner wall 201 of the mounting member 200 and the first support surface 153, and the second inner wall 202 of the mounting member 200 contacts and limits the movement of the outer wall of the second blade portion 102. The outer end 212 of the mounting member 200, which is provided along the first direction of the blade holder 1, has a gap with the tip of the blade 103. The distance is such that the blade 103 is exposed; the trimming blade 100, the recess 151 and the mounting member 200 are all elongated structures arranged along the first direction of the blade holder 1, so that the mounting member 200 can fully press the second blade body 102, so that the mounting member 200 is fixed stably and reliably, so that the blade 103 of the trimming blade 100 is installed on the front side of the blade holder 1, and the installation of the blade 103 facing the rear side of the blade holder 1 is more reliable. There is a gap between the outer end 212 and the tip of the blade 103 so that the tip of the blade is exposed, which facilitates trimming shaving.

[0033] Preferably, the side of the support platform 152 located outside the recess 151 is a second support surface 154. The second support surface 154 is close to the outer edge of the first support surface 153, and the included angle between the first support surface 153 and the second support surface 154 is an obtuse angle. The second support surface 154 is disposed adjacent to the second blade body portion 102 with a gap. This gap setting makes the fine shaving effect better and allows the hair to enter the gap, so that the blade can cut the hair better, resulting in a better fine shaving effect.

[0034] In this embodiment, a limiting wall 16 is provided on the side of the recess 151 adjacent to the first mounting position 14 to limit the third inner wall 203 of the mounting member 200. The third inner wall 203 of the mounting member 200 is provided with a first limiting protrusion 206. The limiting wall 16 is provided with a groove 161 that is adapted to the limiting part and corresponds to the position. The first limiting protrusion 206 is inserted into the groove 161. The insertion of the first limiting protrusion 206 into the groove 161 limits the mounting member 200 in the first direction of the tool holder 1. The limiting part limits the second tool body part 102 to prevent the finishing blade 100 from moving downward.

[0035] Preferably, a positioning recess 162 is formed at the bottom of the groove 161, and an extension 207 is formed at the bottom of the limiting protrusion, the extension 207 being inserted into the positioning recess 162; thereby further limiting the mounting member 200, restricting the mounting member 200 in both the upward and downward directions.

[0036] In this embodiment, the inner walls of the two ends of the recess 151 along the first direction of the tool holder 1 are formed with second limiting protrusions 18, and each of the second limiting protrusions 18 is mutually limiting and cooperating with the two ends of the mounting member 200; specifically, the two ends of the mounting member 200 are respectively provided with limiting recesses 210, and each of the second limiting protrusions 18 is embedded in the limiting recesses 210. The structure realizes the positioning of the mounting member 200, thereby making it more stable after fixing.

[0037] In this embodiment, a bevel 204 is provided on the side of the mounting member 200 opposite to the limiting wall 16. The end of the bevel 204 near the blade 103 is connected to the outer end of the mounting member 200, and the outer end of the mounting member 200 is an arc surface. Multiple grooves 205 arranged in a straight line along the first direction of the blade holder 1 are formed on the bevel 204. The bevel 204 serves as a guide during shaving, and the grooves 205 reduce the force-bearing surface and reduce friction. The angle and width of the bevel can be adjusted according to the actual situation, thereby adjusting the exposure degree of the blade 103 of the finishing blade 100.

[0038] In this embodiment, a recessed mounting surface 208 is formed on the mounting member 200, and a shaving aid 300 is fixed on the mounting surface 208 so that the lubrication surface of the shaving aid 300 is higher than the tip of the razor blade 3, or the lubrication surface of the shaving aid 300 and the tip of the razor blade 3 are on the same horizontal plane. Its structural design makes it easier for the shaving aid 300 to come into contact with the beard or skin during shaving, making shaving more comfortable. The shaving aid is generally in the form of a strip, but it can also be in the form of a block or other shapes. The mounting surface 208 and the shaving aid 300 are fixed with an adhesive, but the fixing method is not limited to this. The shaving aid is generally a known lubricating strip for shaving, which plays a lubricating role during shaving.

[0039] Preferably, both ends of the mounting surface 208 and the side opposite to the limiting wall 16 are formed as blocking walls 209. Each of the blocking walls 209 and the limiting wall 16 respectively limits the shaving aid, thereby limiting the shaving aid after it is fixed.

[0040] In this embodiment, two deformable blades 2 are also included. The deformable blades 2 can be made of metal or plastic. The pressing part 20 of each deformable blade 2 simultaneously presses the end of the razor blade 3 and the end of the mounting part. A through hole 13 is provided on the side of the first mounting position on the blade holder 1. The first bendable part 21 of the deformable blade passes through the through hole 13 and is bent to form a first fastening part 211 that is fastened to the rear side of the blade holder 1. The second bendable part 22 of the deformable blade covers the upper side of the blade holder 1 and is bent to form a fastening part 211 that is fastened to the rear side of the blade holder 1. The second fastening part 221, or the first bendable part 21 of the deformable blade body covers the lower side of the blade holder 1 and is bent to form the first fastening part 211 fastened to the rear side of the blade holder 1, and the second bendable part 22 of the deformable blade body covers the upper side of the blade holder 1 and is bent to form the second fastening part 221 fastened to the rear side of the blade holder 1, thereby realizing the fixation of the multi-layer shaving blades, and the fixing and installation are also relatively convenient. The blocking walls at both ends of the shaving aid also limit one side wall of the deformable blade body, and the other side wall of the deformable blade body 2 is limited by the positioning wall on the blade holder.

[0041] Example 2: The razor head structure described in this embodiment is generally similar to that of Embodiment 1, but the difference is that: the first mounting position 14 of the razor holder 1 is provided with two first positioning structures 11 for positioning the razor blade 3. The two first positioning structures 11 are arranged at intervals along the first direction of the razor holder 1. Each first positioning structure 11 includes multiple first positioning spaces 116 arranged at intervals along the second direction of the razor holder 1. Each first positioning space 116 includes a first inner surface 113 and a second inner surface 115 arranged opposite to each other. The two ends of the base 31 of the razor blade 3 are respectively inserted into the two first positioning spaces 116 arranged at intervals along the first direction of the razor holder 1. Each first positioning structure 11 also includes multiple first positioning ribs 111 arranged at intervals along the second direction of the razor holder 1. A first inner surface 113 and a second inner surface 115 are formed on each two adjacent first positioning ribs 111.

[0042] Example 3: The razor head structure described in this embodiment is generally similar to that of Embodiment 2, but the difference is that at least one of the first inner surface 113 and the second inner surface 115 is an inclined side surface. It can be that the first inner surface 113 is an inclined side surface, or the second inner surface 115 is an inclined side surface, or both the first inner surface 113 and the second inner surface 115 are inclined side surfaces. Therefore, the inclined side surface increases the outer opening of the first positioning space 116, which facilitates the insertion of the base 31 of the razor blade 3 into the first positioning space 116 for positioning. After the trimming blade is installed in the second mounting position 15, the deformable plate is used to press the end of the mounting member and the end of the multi-layer razor blade, and the deformable plate is fastened to the blade holder, thereby fixing the trimming blade and the multi-layer razor blade to the blade holder.

[0043] In this embodiment, the first mounting position 14 is further provided with at least one second positioning structure 12 for positioning the razor blade 3. The second positioning structure 12 is located between two first positioning structures 11. Each second positioning structure 12 includes a plurality of second positioning spaces arranged in a straight line along the second direction of the blade holder 1. Each second positioning space includes a third inner surface 122 and a fourth inner surface 123 arranged opposite to each other. The middle part of the base 31 of the razor blade 3 is inserted into the second positioning space. At least one of the third inner surface 122 and the fourth inner surface 123 is an inclined side surface. Each second positioning structure 12 also includes a plurality of second positioning ribs 121 arranged in a straight line along the second direction of the blade holder 1. A third inner surface 122 and a fourth inner surface 123 are formed on each two adjacent second positioning ribs 121. The second positioning structure 12 makes the razor blade 3 more stable after assembly. The third inner surface 122 or the fourth inner surface 123 can be an inclined side, or both the third inner surface 122 and the fourth inner surface 123 can be inclined sides. Therefore, the inclined side increases the outer opening of the second positioning space, which makes it easier for the base 31 of the razor blade 3 to be inserted into the second positioning space for positioning.

[0044] In this embodiment, at least one of the first positioning rib 111 and the second positioning rib 121 located below the blade portion 32 of the razor blade 3 is provided with a support portion 117. The top of the support portion 117 is provided with an inclined support surface 118, which contacts the inner wall of the blade portion 32 of the razor blade 3 to provide support for the blade portion 32. The inclination angle between the inclined support surface 118 and the blade portion 32 of the razor blade 3 relative to the first mounting position 14 is α, where α = 18°-22°, with a preferred range of α = 20°. The inclination of the inclined support surface and the blade portion 32 of the razor blade 3 are mutually adapted, resulting in a more stable and reliable support for the razor blade 3. The included angle between the blade portion 32 of the razor blade 3 and the base 31 is an obtuse angle.

[0045] In this embodiment, both the first positioning rib 111 and the second positioning rib 121 include a first rib 112, and the end of the first rib 112 located below the blade portion 32 of the razor blade 3 forms a support portion.

[0046] Preferably, both the first positioning rib 111 and the second positioning rib 121 further include a second rib 114. The first rib 112 and the second rib 114 are arranged along a first direction, and there is a positional difference between the first rib 112 and the second rib 114 in a second direction of the tool holder 1. The first positioning rib 111 and the second positioning rib 121 can be a separate structure or an integral structure. The distance between the inclined support surface 118 of the first rib 112 and the inner bottom surface of the positioning space is greater than the distance between the top surface of the second rib 114 and the inner bottom surface of the positioning space. In the case of an integral structure, the first rib 112 and the second rib 114 are connected to each other through a connecting part.

[0047] In the first positioning structure 11, a first inner surface 113 is formed on one side of the first rib 112 facing the rear side of the base 31 of the razor blade 3, and a second inner surface 115 is formed on one side of the second rib 114 facing the front side of the base 31 of the razor blade 3, so that the first inner surface 113 and the second inner surface 115 are staggered.

[0048] In the second positioning structure 12, a third inner surface 122 is formed on one side of the first rib 112 facing the rear side of the base 31 of the razor blade 3, and a fourth inner surface 123 is formed on one side of the second rib 114 facing the front side of the base 31 of the razor blade 3, so that the third inner surface 122 and the fourth inner surface 123 are misaligned.

[0049] The aforementioned misalignment increases the distance for limiting the end of the razor blade 3, and the first rib 112 and the second rib 114 have a positional difference in the second direction of the blade holder 1, so that there is a clearance space between two adjacent first ribs 112 and two adjacent second ribs 114, thereby further improving the convenience of inserting the base 31 of the razor blade 3 into the first positioning space 116 and the second positioning hole.

[0050] Preferably, the second positioning structure 12 can be set in two places, and the second positioning ribs 121 of the two second positioning structures 12 are arranged symmetrically to each other.

[0051] In this embodiment, the blade portion 32 of the bent blade 3 has a length of b in the second direction of the blade holder 1, where b is 1mm. This structural design achieves a shorter blade portion than that of the wide-blade blades in the prior art (the blade portion of the prior art has a length of 1.4mm in the second direction of the blade holder 1). This increases the distance between the blade of one bent blade 3 and the back of the other bent blade 3 in two adjacent layers of bent blades 3, making it easier to clean up stray hairs and shave or trim. It also solves the technical problem of the wide-blade blades (whose blade portion has a length of 1.4mm in the second direction of the blade holder) limiting the efficiency of hair removal and shaving comfort. Therefore, a more precise design is needed, making this invention suitable for the stable installation of narrow-blade blades and improving the efficiency of hair removal.

[0052] Finally, the first direction is the X-axis direction, and the second direction is the Y-axis direction.
