Description

Technical Field

[0001] This utility model relates to the field of recording equipment technology, specifically to a razor, and more specifically to a safety razor with a floating lubricating strip structure. Background Technology

[0002] In the field of shaver technology, shavers with lubrication functions have been widely adopted. Currently, most lubricated shavers on the market have significant technical flaws: their lubrication strip is integrally molded with the blade holder, preventing the lubrication strip from floating independently. Some products also use a "T"-shaped lubrication strip structure, or glue the lubrication strip to the blade holder; these methods all constitute fixed structures.

[0003] Due to the limitations of the fixed structure mentioned above, the lubricating strip of the razor cannot adaptively adjust to the contours of the skin surface during use. When the user's facial skin has different curvatures or undulations, the fixed lubricating strip cannot maintain good contact with the skin at all times. This not only affects the lubrication effect but may also cause the blade to come into direct contact with the skin, increasing the risk of cuts, stings, and other injuries during shaving, thus failing to provide the user with a comfortable shaving experience. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a razor that, by setting a floating lubricating strip, lubricates the skin before shaving and then engages the blade after applying pressure, thereby reducing the risk of scratches, improving comfort, and adapting to different hair densities.

[0005] The technical solution of this utility model is to provide a shaver, including a shaver head, the shaver head including a shaver holder, and lubricating strips provided on both sides of the shaver holder. A blade is fixedly installed on the shaver holder, and the blade is located between the lubricating strips on both sides. The lubricating strips are floatingly installed on the shaver holder by means of a floating component. The end face of the lubricating strip away from the floating component is higher than the end face of the blade.

[0006] Compared with the prior art, the shaver of this utility model has the following advantages: by installing the lubricating strip on the shaver holder through the floating component and having its end face away from the floating component higher than the blade end face, the lubricating strip first contacts the skin to play a lubricating role during shaving, and can float to allow the blade to intervene when force is applied. This can reduce the risk of scratches and adapt to different skin undulations and hair densities, thereby improving shaving comfort and safety.

[0007] As an improvement, both sides of the blade holder are provided with mounting grooves for accommodating the lubricating strip. Each end of the mounting groove has a sliding groove on its sidewall, and each end of the lubricating strip has a slider. The sliders at both ends slide and engage with the sliding grooves at both ends. With this structure, by providing mounting grooves for accommodating the lubricating strip on both sides of the blade holder, and by using sliding grooves on the sidewalls of the mounting grooves and sliders at both ends of the lubricating strip to achieve a sliding engagement, the lubricating strip can flexibly float along the sliding grooves within the mounting grooves, thus adaptively adjusting to the contours of the skin during shaving.

[0008] As an improvement, the floating assembly includes a floating frame mounted on the razor holder. The floating frame has elastic feet on both sides, which support the lubricating strip. These elastic feet provide a pushing force to the corresponding lubricating strip, bringing it closer to the razor's working surface. This structure ensures the lubricating strip remains in a floating state close to the skin, allowing it to contact the skin before the blades during shaving for thorough lubrication. The elasticity of the feet also allows the lubricating strip to adapt to skin contours, smoothly pressing down to engage the blades under pressure. This effectively improves shaving comfort and fit, reduces the risk of nicks, and enhances adaptability to different skin conditions.

[0009] As an improvement, the floating frame has elastic feet at both ends on both sides. The elastic feet at both ends on the same side extend into the corresponding grooves at both ends of the mounting slot, and are supported on the corresponding sliders. With this structure, by providing elastic feet at both ends of the floating frame, which extend into the corresponding grooves at both ends of the mounting slot and are supported on the sliders at both ends of the lubricating strip, a symmetrical elastic support structure is formed at both ends. This ensures that the lubricating strip is subjected to uniform force during floating, significantly improving structural stability.

[0010] As an improvement, the elastic foot is a slanted arm, the end of which extends into a corresponding groove and rests against the slider. With this structure, the elastic deformation characteristics of the slanted arm provide a stable thrust to the lubricating strip, ensuring it remains in a floating state close to the skin. The angled design of the slanted arm optimizes the cushioning effect of the elastic support, allowing the lubricating strip to contact the skin before the blades for thorough lubrication during shaving, and also enabling the lubricating strip to float smoothly along the groove under pressure through the elastic bending of the slanted arm.

[0011] As an improvement, the elastic foot includes a lateral support foot, the end of which is provided with an elastic element. Both the end of the support foot and the elastic element extend into the groove, with the end of the elastic element abutting against the slider. With this structure, the lateral support foot enhances the stability of the elastic foot within the groove, preventing lateral displacement during floating. The elastic element provides a continuous elastic thrust to the lubricating strip, ensuring it always contacts the skin before the blade for pre-lubrication. When the skin undulates or shaving force is applied, the elastic element deforms, causing the lubricating strip to float smoothly along the groove. Combined with the guiding effect of the lateral support foot, this ensures even force distribution at both ends of the lubricating strip and a stable floating trajectory, effectively preventing tilting or jamming. While improving structural reliability, the precise elastic support mechanism reduces the risk of shaving and enhances comfort and fit during shaving.

[0012] As an improvement, a connecting frame is provided in the middle of the floating frame, which is fastened to the tool holder, and the elastic foot is connected to the connecting frame. With this structure, the fastening connecting frame can ensure a rigid connection between the floating frame and the tool holder, avoiding displacement or shaking during floating, and facilitating quick disassembly and maintenance; the elastic foot achieves uniform force transmission through the connecting frame, so that the lubricating strips on both sides are subjected to consistent force during floating, and with the sliding guide of the sliders and grooves at both ends, it effectively prevents the lubricating strips from tilting or getting stuck; this design not only enhances the overall structural stability through the middle fastening, but also, with the linkage between the elastic foot and the connecting frame, keeps the lubricating strips stable when floating with the skin's undulations.

[0013] As an improvement, the connecting frame is provided with a boss, and the side wall of the boss is provided with a protrusion. The tool holder is provided with an insert, and the inner wall of the insert is provided with a limiting step. The boss is embedded in the insert, and the protrusion is engaged with the limiting step. With this structure, by setting the boss and side wall protrusion on the connecting frame, a fastening structure is formed with the limiting step on the inner wall of the tool holder insert, which can achieve precise positioning and rigid connection between the floating frame and the tool holder. After the boss is embedded in the insert, the protrusion is engaged with the limiting step, which can effectively prevent the floating frame from shifting or loosening during use, and enhance the stability of the overall structure.

[0014] As an improvement, the connecting frame is provided with two bosses, each with protrusions on both sides; correspondingly, the tool holder is provided with two inserts, each with limiting steps on both sides; the two bosses are embedded in the two inserts in a one-to-one correspondence, and the protrusions on both sides of each boss are engaged with the corresponding limiting steps. With this structure, the engagement design of the protrusions on both sides and the limiting steps effectively resists the lateral forces generated during floating, preventing the floating frame from shifting or loosening; the corresponding cooperation between the two bosses and the inserts enables precise positioning of the floating frame and the tool holder, ensuring uniform transmission of the supporting force of the elastic feet to the lubricating strips on both sides.

[0015] As an improvement, the lubricating strip includes a support frame and a lubricating pad, with the lubricating pad fixedly connected to the side of the support frame away from the floating component; both ends of the support frame are equipped with the sliders. With this structure, the support frame provides rigid support for the lubricating pad, ensuring its shape stability during floating and preventing deformation due to stress from affecting the lubrication effect.

[0016] As an improvement, the lubricating strip is a rolling strip, with sliders at both ends. With this structure, during shaving, the rolling strip rolls in the direction of the shaving motion, continuously and evenly applying lubricant to the skin surface. Simultaneously, the rolling process provides a gentle massage effect, promoting local blood circulation. Rolling friction replaces traditional sliding contact, significantly reducing mechanical irritation to the skin. Combined with the sliding guidance of the sliders and grooves, this ensures a smooth rolling trajectory, improving lubrication efficiency and reducing stinging sensations during shaving, providing users with a more comfortable and skin-friendly experience.

[0017] As an improvement, both sides of the tool holder are provided with protruding strips, and both ends of the connecting frame are provided with matching insertion grooves for the protruding strips. The protruding strips are embedded into the insertion grooves on both sides in a one-to-one correspondence, and the protruding strips and their corresponding insertion grooves are connected by a snap-fit. With this structure, by setting a snap-fit ​​structure between the protruding strips on both sides of the tool holder and the insertion grooves at both ends of the connecting frame, precise positioning and quick assembly / disassembly of the floating frame and the tool holder can be achieved. After the protruding strips are embedded into the insertion grooves, they are locked by the snap-fit, which can effectively resist lateral forces during the floating process, prevent the connecting frame from shifting or loosening, and enhance the stability of the overall structure.

[0031] like Figures 1 to 4 As shown in the figure, this specific embodiment discloses a razor, including a razor head, which includes a razor holder 1. Lubricating strips 2 are provided on both sides of the razor holder 1, and a blade 3 is fixedly mounted on the razor holder 1, with the blade 3 located between the lubricating strips 2 on both sides.

[0032] The tool holder 1 has mounting grooves 101 on both sides, the size of which matches the size of the lubricating strips 2. The lubricating strips 2 on both sides are installed in the mounting grooves 101 on both sides. Sliding grooves 102 are provided on the side walls at both ends of the mounting grooves 101, and sliders 201 are provided at both ends of the lubricating strips 2. The sliders 201 at both ends slide and engage with the sliding grooves 102 at both ends. A mounting position 103 is provided on the upper side of the tool holder 1 (for ease of description, the working surface of the tool head is the upper side, and the side opposite the working surface is the lower side). The blade 3 is installed on the mounting position 103, and both ends of the blade 3 are pressed and fixed by fixing strips 301.

[0033] The lubricating strip 2 includes a support frame 202 and a lubricating pad 203. The lubricating pad 203 is fixedly connected to the side of the support frame 202 away from the floating component. The slider 201 is provided at both ends of the support frame 202.

[0034] Both sides of the lubricating strip 2 are floatingly mounted on the tool holder 1 through a floating assembly. When the lubricating strip 2 is not under force, the upper end surface of the lubricating strip 2 is higher than the upper end surface of the blade 3.

[0035] The floating assembly includes a floating frame 4. The floating frame 4 is mounted on the blade holder 1, and elastic feet are provided on both sides of the floating frame 4. The elastic feet on both sides are supported on the lubricating strips 2, and the elastic feet provide a pushing force to the corresponding lubricating strips 2 towards the working surface of the shaver.

[0036] The floating frame 4 has a connecting frame 401 in the middle, which is fastened to the tool holder 1. The elastic foot is connected to the connecting frame 401. The connecting frame 401 has a boss 402, and the side wall of the boss 402 has a protrusion 403. The tool holder 1 has an embedding part 104, and the inner wall of the embedding part 104 has a limiting step 105. The boss 402 is embedded in the embedding part 104, and the protrusion 403 is fastened to the limiting step 105. In this specific embodiment, the connecting frame 401 is provided with two protrusions 402, and each of the protrusions 402 has protrusions 403 on both sides; correspondingly, the tool holder 1 is provided with two embedding parts 104, and each embedding part 104 has limiting steps 105 on both sides inside; the two protrusions 402 are embedded in the two embedding parts 104 in a one-to-one correspondence, and the protrusions 403 on both sides of each protrusion 402 are fastened to the corresponding limiting steps 105 in a one-to-one correspondence.

[0037] The tool holder 1 has protruding strips 106 on both sides, and the connecting frame 401 has an insert groove 404 at both ends that matches the protruding strips 106. The protruding strips 106 are inserted into the insert grooves 404 on both sides in a one-to-one correspondence. The protruding strips 106 and the corresponding insert grooves 404 are connected by a snap-fit. The side wall of the protruding strip 106 has a first snap-fit ​​block 107. The insert groove 404 has a second snap-fit ​​block 405 corresponding to the first snap-fit ​​block 107. When the protruding strip 106 is inserted into the insert groove 404, the first snap-fit ​​block 107 and the second snap-fit ​​block 405 are snapped together.

[0038] The connecting bracket 401 has elastic feet at both ends on both sides. These elastic feet extend into the corresponding sliding grooves 102 at both ends of the mounting slot 101, and are supported on the lower side of the corresponding slider 201. In this specific embodiment, the elastic foot is a slanted arm 5, the end of which extends into the corresponding sliding groove 102 and abuts against the lower side of the slider 201.

[0039] The working process of the shaver disclosed in this specific embodiment is as follows: When the shaver contacts the skin, the lubricating strip 2, which is higher than the upper surface of the blade 3, contacts the skin first. Under the action of shaving force, the lubricating strip 2 floats downward along the slide groove 102 of the mounting groove 101 through the sliders 201 at both ends. At this time, the elastic feet of the inclined arms 5 on both sides of the floating frame 4 are deformed by force, providing a buffer thrust for the lubricating strip 2. As the lubricating strip 2 is pressed down, the blade 3 gradually contacts the skin to perform the shaving action. When the shaving force disappears, the elastic feet elastically reset, causing the lubricating strip 2 to rise back, always maintaining a state higher than the blade 3, realizing the dynamic process of "lubricating before shaving".

[0040] When not under pressure, the lubricating strip 2 is always higher than the blade 3, making contact with the skin first for pre-lubrication. When under pressure, it can adaptively float with the skin's undulations, preventing the blade 3 from directly scraping the skin. The symmetrical elastic support and snap-fit ​​design on both sides ensures that the lubricating strip 2 floats smoothly, reducing tilting and jamming, improving shaving comfort and safety, and effectively reducing the risk of shaving injuries. Example

[0041] like Figures 5 to 7 As shown, this specific embodiment discloses a razor. The razor disclosed in this specific embodiment differs from the razor disclosed in Embodiment 1 in that: the elastic foot includes a transverse support foot 6, and the end of the support foot is provided with an elastic element. Both the end of the support foot and the elastic element extend into the sliding groove 102', and the end of the elastic element abuts against the slider 201'. The elastic element is a spring 7, and a positioning post 601 is provided on the upper side of the end of the support foot. The lower end of the spring 7 is fitted outside the positioning post 601, and the upper end of the spring 7 abuts against the lower end surface of the slider 201'.

[0042] The working process of the shaver disclosed in this specific embodiment is as follows: When the shaver contacts the skin, the upper surface of the lubricating strip 2' contacts the skin before the blade 3'. At this time, the spring 7 at the end of the transverse support foot 6 abuts against the slider 201', providing the lubricating strip 2' with a pushing force to move closer to the working surface. When the shaving force is applied, the spring 7 is compressed, causing the lubricating strip 2' to float downward along the slide groove 102' through the slider 201'. The blade 3' gradually engages in shaving. When the skin undulates, the spring 7 can adaptively adjust the support force through deformation. After the shaving force disappears, the spring 7 returns to its original position and pushes the lubricating strip 2' back up, so that the lubricating strip 2' always remains higher than the blade 3'. Example

[0043] like Figures 8 to 9 As shown, this specific embodiment discloses a razor. The razor disclosed in this specific embodiment differs from the razor disclosed in Embodiment 1 in that: the lubricating strip 2'' is a rolling strip, and both ends of the rolling strip are provided with the slider 201'', and the cross-section of the rolling strip is circular.

[0044] The floating component of the razor in this specific embodiment can also be the floating component of the razor in Embodiment 2.
