Description

Technical Field

[0001] This utility model relates to the field of electric hair clippers, specifically to a low-friction electric hair clipper head structure with a cylindrical friction pair. Background Technology

[0002] As a commonly used hair-cutting tool, the design of the blade structure of electric clippers directly affects the cutting effect and user experience. Traditional electric clipper heads usually adopt a spring-pressing method to keep the moving blade and the fixed blade in proper contact to achieve the cutting function. Currently, most electric clipper heads on the market adopt a single spring or double spring structure, such as the double spring structure of an electric clipper head disclosed in CN117644538A, in which the fixed bracket is fixedly connected to the first spring and the second spring respectively. The first spring presses the moving blade against the fixed blade, and the sliding part of the second spring slides along the slide groove of the movable blade holder to realize the reciprocating parallel movement of the fixed blade and the moving blade [1].

[0003] Regarding the blade movement mechanism, CN222430805U discloses a blade structure for electric clippers, which sets a steel wire between the fixed blade and the moving blade to guide the slider and reduce friction damage [2]. WO2022134212A1 proposes a parallel running device for electric clipper heads, which includes a moving blade, a fixed blade, a blade holder, a blade head support and a compression spring. The compression spring includes a connecting part and sliding parts connected to the connecting part at both ends. The connecting part is connected to the blade head support and the sliding part is located in a groove on the blade holder [3].

[0004] To address the issue of blade lifespan, CN221936825U discloses a double-spring structure for electric clipper heads with an oil reservoir in the slide groove. When the blade moves, lubricating oil flows out to lubricate the moving parts, thereby improving the lifespan of the blade spring [4]. Similarly, CN213197636U proposes an oil storage and lubrication device for electric clipper heads, which sets a lubrication component in the moving blade assembly so that a small amount of lubricating oil can be continuously added to the contact surface between the fixed blade and the moving blade [5].

[0005] However, existing electric hair clipper head structures still have the following technical problems: First, in traditional spring-compression structures, the spring stiffness and initial torque are not properly matched, which can easily lead to gap vibration between the moving and stationary blades. This causes the moving blade movement to exhibit non-linearity, resulting in momentary jamming or jumping, affecting the smoothness and evenness of shaving. Second, the large contact area of ​​the planar friction pair between the moving and stationary blades means that even with lubricant, significant friction is still generated, accelerating component wear and gradually increasing the gap between the blades, thus affecting shaving performance. Furthermore, existing lubrication structures often fail to ensure a continuous and even release of lubricant, leading to increased friction after prolonged use. This not only affects the cutting effect but also increases the motor load and shortens the lifespan of the hair clipper. Finally, the complex structure of traditional blade heads easily accumulates beard debris and skin oils, hindering the normal movement of the moving blades and making thorough cleaning difficult.

[0006] Therefore, there is an urgent need for an electric clipper head structure that can reduce friction, improve motion smoothness, extend service life, and is easy to maintain. Utility Model Content

[0007] To address the issues of smooth movement, shaving effect, durability and reliability, and cleaning and maintenance in electric hair clipper heads, and to achieve technical effects such as improved friction and movement performance, optimized pressure and spacing control, precise positioning spacing, improved lubrication and maintenance, and enhanced structural stability, this utility model provides a low-friction electric hair clipper head structure with a cylindrical friction pair.

[0008] The technical solution adopted by this utility model to solve its technical problem is as follows: it includes: a fixed blade holder and a fixed blade, wherein the fixed blade is fixed on the fixed blade holder; a movable blade holder and a movable blade installed thereon, wherein the movable blade cooperates with the fixed blade to perform a shearing action; and a pressure applying component that provides uniform downward pressure and presses against the first guide member and the movable blade holder.

[0009] The relative motion guide structure includes a first guide member and a second guide member. The pressure-applying component is disposed above the first guide member and serves as a positioning reference to control the distance between the movable blade and the fixed blade. The second guide member is disposed on the movable blade holder and forms a cylindrical friction pair with the first guide member.

[0010] The lubrication component is used to continuously release lubricant to the friction surfaces of the moving and stationary blades to achieve low-friction movement.

[0011] Preferably, the pressure-applying component is a spring sheet (2), which is disposed above the first guide member.

[0012] Preferably, the first guide is a steel shaft (3), which is set below the spring sheet (2) as the main load-bearing element and accurately positions the distance between the moving blade (7) and the fixed blade (8); the second guide is a roller (5), which is installed on the moving blade holder (6) and forms a cylindrical friction pair with the steel shaft (3).

[0013] Preferably, the lubricating component is lubricating cotton (4).

[0014] Preferably, the elastic coefficient of the spring is 5–6 N / mm, and uniform pressure is transmitted through the steel axis moving tool holder to make the moving tool closely adhere to the fixed tool.

[0015] Furthermore, the diameter of the steel shaft is 2.0–2.5 mm, and the distance between the moving tool and the fixed tool is controlled as a positioning reference to be 0.15–3.5 mm.

[0016] Furthermore, the roller diameter is 1.5–2.0 mm, and the cylindrical friction pair with the steel shaft reduces the contact area to less than 10% of that in conventional designs.

[0017] Furthermore, the lubricant release rate of the lubricating cotton is 0.05–0.07 ml / hour, continuously covering the friction surfaces of the moving and stationary blades.

[0018] Preferably, it also includes an adjustment mechanism for fine-tuning the distance between the moving blade and the stationary blade.

[0019] Furthermore, the steel shaft has a double-ended design, with the fixed tool holder and the moving tool post connected to each end respectively.

[0020] Preferably, the lubricating cotton is a replaceable structure.

[0021] Furthermore, the contact surface between the moving blade and the fixed blade is provided with an oil reservoir to store lubricant and reduce friction.

[0022] The beneficial effects of this invention are as follows: The cylindrical friction pair formed by the steel shaft and roller reduces the contact area by more than 90% compared to traditional planar friction pairs, greatly reducing frictional resistance, energy loss, and making the moving blade move more smoothly; the spring plate provides uniform downward pressure, ensuring even force distribution between the moving and fixed blades during the cutting process, guaranteeing the flatness and quality of the cut surface; the steel shaft, as the main load-bearing shaft, is positioned below the spring plate to support it and accurately position the distance between the moving and fixed blades; the lubricating cotton continuously releases lubricant to the friction surface, further reducing friction, wear, and extending the blade's lifespan; the cylindrical friction pair formed by the steel shaft and roller makes the force distribution on the moving blade holder more reasonable during movement, reducing wobbling or offset caused by uneven force distribution. Compared with existing technologies, this invention solves the problems of unstable movement, poor shaving effect, poor durability, and difficult cleaning and maintenance of traditional electric clipper heads, improving the overall performance and user experience of electric clippers.

[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0028] like Figure 1 As shown, this utility model provides a low-friction electric clipper head structure with a cylindrical friction pair, which mainly includes several key components such as a fixed blade holder 1, a fixed blade 8, a moving blade holder 6, a moving blade 7, a spring 2, a steel shaft 3, a roller 5, and lubricating cotton 4.

[0029] The fixed blade 8 is securely mounted on the fixed blade holder 1, forming a fixed reference surface for shearing. The fixed blade 8 is made of high-hardness alloy steel, and its surface is precision ground to ensure optimal fit with the moving blade 7. The shearing edge of the fixed blade 8 undergoes a special heat treatment process, achieving a hardness of HRC58-62. This design ensures that it is not easily worn during long-term use, extending its service life.

[0030] The movable blade holder 6 is designed to support the movable blade 7, which is fixedly mounted on the movable blade holder 6 and works in conjunction with the fixed blade 8 to perform the shearing action. The movable blade holder 6 is made of POM engineering plastic material, which not only reduces the overall weight but also ensures the strength and stability of the structure. The movable blade 7 is also made of high-hardness alloy steel, and its shearing edge forms a precise fit with the shearing edge of the fixed blade 8, thereby achieving efficient shearing function.

[0031] The spring 2 is mounted above the fixed tool holder 1, providing uniform downward pressure to the entire tool head structure. The spring 2 has a spring constant of 5-6 N / mm and transmits uniform pressure to the moving tool holder 6 through the steel shaft 3, ensuring that the moving tool 7 is in close contact with the fixed tool 8. In a preferred embodiment, the spring constant of the spring 2 is 5.5 N / mm, at which point the downward pressure is most uniform, ensuring a stable contact pressure between the moving tool 7 and the fixed tool 8.

[0032] The steel shaft 3, serving as the main load-bearing element, is positioned below the spring piece 2 and precisely positions the distance between the moving blade 7 and the fixed blade 8. The diameter of the steel shaft 3 is 2.0-2.5 mm, acting as a positioning reference to control the distance between the moving blade 7 and the fixed blade 8 at 0.15-3.5 mm. In a preferred embodiment, the diameter of the steel shaft 3 is 2 mm, which optimally controls the distance between the moving blade 7 and the fixed blade 8 to 0.15 mm, ensuring both effective shearing and minimal frictional resistance. The steel shaft 3 is made of high-precision bearing steel, with a surface that has undergone precision grinding and chrome plating, achieving a hardness of HRC60 or higher to ensure no deformation during long-term use.

[0033] like Figure 2 and Figure 3 As shown, the roller 5 is mounted on the moving tool holder 6, forming a cylindrical friction pair with the steel shaft 3. The diameter of the roller 5 is 1.5-2.0 mm, and the cylindrical friction pair with the steel shaft 3 reduces the contact area to less than 10% of that in conventional designs. In a preferred embodiment, the diameter of the roller 5 is 2 mm, in which case the contact area of ​​the cylindrical friction pair with the steel shaft 3 is only 8% of that of a conventional planar friction pair, significantly reducing frictional resistance. The roller 5 is made of bearing steel, and its surface is precision ground to ensure a minimum coefficient of friction with the steel shaft 3.

[0034] Lubricating cotton 4 is installed at an appropriate position on the moving blade holder 6, continuously releasing lubricant to the friction surfaces of the moving blade 7 and the fixed blade 8. The lubricant release rate of lubricating cotton 4 is 0.05-0.07 ml / hour, continuously covering the friction surfaces of the moving blade 7 and the fixed blade 8. In a preferred embodiment, the lubricant release rate of lubricating cotton 4 is 0.06 ml / hour, which ensures that the friction surfaces between the moving blade 7 and the fixed blade 8 remain lubricated without over-lubrication. Lubricating cotton 4 is made of a special porous material, possessing excellent oil absorption and slow-release properties, enabling stable lubricant release over a long period.

[0035] like Figure 4 As shown, the low-friction electric clipper head structure of this utility model also includes an adjustment mechanism for fine-tuning the distance between the moving blade 7 and the fixed blade 8. This adjustment mechanism includes a fine-tuning screw; rotating the screw precisely controls the position of the steel shaft 3, thereby adjusting the distance between the moving blade 7 and the fixed blade 8. The screw pitch is such that for each 12° adjustment, the fixed blade moves backward by 0.8mm, allowing for a total of 4 adjustments and 5 settings, achieving precise control.

[0036] The steel shaft 3 adopts a double-headed design, with the fixed blade holder 1 and the moving blade holder 6 connected at both ends respectively. This design enhances the stability of the overall structure, ensures the parallelism between the moving blade 7 and the fixed blade 8, and avoids jamming or unevenness during the shearing process.

[0037] The lubricating cotton 4 is designed as a replaceable structure, facilitating maintenance and replacement. The lubricating cotton 4 is fixed to the fixed tool holder 1 via a snap-fit ​​structure, allowing for easy disassembly and replacement without tools, greatly improving ease of use.

[0038] The contact surface between the moving blade 7 and the fixed blade 8 is provided with oil reservoirs to store lubricant and reduce friction. The oil reservoirs are distributed in a grid pattern on the back of the moving blade 7, with a total area of ​​approximately 30% of the back area of ​​the moving blade 7 and a depth of 0.2 mm. This effectively stores lubricant and distributes it evenly on the friction surface, further reducing frictional resistance.

[0039] The working principle of this low-friction electric clipper head structure is as follows: The motor drives the moving blade holder 6 to move the moving blade 7 in a reciprocating motion, forming a shearing action with the fixed blade 8. During this process, the cylindrical friction pair formed by the steel shaft 3 and the roller 5 greatly reduces the contact area, lowering the frictional resistance to less than 10% of traditional designs. Simultaneously, the lubricating cotton 4 continuously releases lubricant, covering the friction surfaces of the moving blade 7 and the fixed blade 8, further reducing frictional resistance. The spring plate 2 provides uniform downward pressure, ensuring appropriate contact pressure between the moving blade 7 and the fixed blade 8, guaranteeing the shearing effect without increasing frictional resistance.

[0040] Through the above structural design, the low-friction electric clipper head structure of this utility model significantly reduces operating friction, improves cutting efficiency, extends battery life, and at the same time reduces noise and vibration, thus enhancing the user experience. Example

[0041] like Figures 1 to 4 As shown, this utility model provides a low-friction electric clipper head structure with a cylindrical friction pair, including a fixed blade holder 1, a spring 2, a steel shaft 3, a lubricating cotton 4, a roller 5, a moving blade holder 6, a moving blade 7, and a fixed blade 8.

[0042] In terms of overall structure, the fixed blade 8 is fixed on the fixed blade holder 1, and the moving blade 7 cooperates with the fixed blade 8 to perform the shearing action. The spring plate 2 provides uniform downward pressure, pressing it against the steel shaft 3 and the moving blade holder 6. The steel shaft 3 serves as the main load-bearing shaft, supporting the spring plate 2 and precisely positioning the distance between the moving blade 7 and the fixed blade 8. The roller 5 is mounted on the moving blade holder 6, forming a cylindrical friction pair with the steel shaft 3. The lubricating cotton 4 continuously releases lubricant to the friction surfaces of the moving blade 7 and the fixed blade 8.

[0043] like Figure 4 As shown, the diameter of the steel shaft 3 is 2.0-2.5 mm, and the distance between the moving blade 7 and the fixed blade 8, which serves as a positioning reference, is 0.15-3.5 mm. In a preferred embodiment, the diameter of the steel shaft 3 is 2 mm, and the distance between the moving blade 7 and the fixed blade 8 is 0.15 mm. This spacing design ensures the shearing effect while reducing frictional resistance and extending the tool life.

[0044] like Figure 3 As shown, the diameter of roller 5 is 1.5-2.0 mm, and the cylindrical friction pair with steel shaft 3 reduces the contact area to less than 10% of that in conventional designs. In a preferred embodiment, the diameter of roller 5 is 2 mm, in which case the contact area formed with steel shaft 3 is only 8% of that of a conventional planar friction pair, significantly reducing frictional resistance. The contact area between steel shaft 3 and roller 5 is reduced by more than 90% compared to a conventional planar friction pair. This design significantly reduces the frictional resistance between moving blade 7 and fixed blade 8, reduces the motor load, and extends the battery life of the electric clipper.

[0045] like Figure 2 As shown, during the assembly of the entire cutter head structure, firstly, the moving cutter 7 is installed onto the moving cutter holder 6, then the lubricating cotton 4 is inserted into the fixed position of the moving cutter holder 6, and next, the roller 5 is installed in the preset position of the moving cutter holder 6; then, the spring 2 is installed into the fixed cutter holder 1, and the steel shaft 3 is also installed into the fixed cutter holder 1 at the same time; finally, the fixed cutter holder 1 and the fixed cutter 8 are locked with screws. The spring 2 provides uniform downward pressure to ensure that the moving cutter 7 and the fixed cutter 8 maintain appropriate contact pressure, and the lubricating cotton 4 is used to continuously release lubricant. The steel shaft 3 is located below the spring 2, forming a cylindrical friction pair with the roller 5 on the moving cutter holder 6, while precisely controlling the distance between the moving cutter 7 and the fixed cutter 8.

[0046] When the electric hair clipper is working, the motor drives the moving blade 7 to reciprocate left and right, and the shearing action is completed through the cooperation between the moving blade 7 and the fixed blade 8. Due to the use of a cylindrical friction pair structure formed by the steel shaft 3 and the roller 5, the contact area is greatly reduced, frictional resistance is lowered, making the electric hair clipper run more smoothly and reducing energy consumption. At the same time, the lubricating cotton 4 continuously releases lubricant to the friction surface between the moving blade 7 and the fixed blade 8, further reducing friction, improving shearing efficiency, and extending the service life of the blade head.

[0047] This low-friction electric clipper head structure reduces the contact area by more than 90% through the cylindrical friction pair design formed by the steel shaft 3 and the roller 5. At the same time, it precisely controls the distance between the moving blade 7 and the fixed blade 8, achieving a low-friction, high-efficiency, and low-noise cutting effect, which greatly improves the user experience and energy utilization efficiency of the electric clipper. Example

[0048] like Figure 1 and Figure 2 As shown, the structure of this low-friction electric clipper head includes a fixed blade holder 1, a spring 2, a steel shaft 3, a lubricating cotton 4, a roller 5, a moving blade holder 6, a moving blade 7, and a fixed blade 8.

[0049] The fixed blade 8 is fixed on the fixed blade holder 1, and the moving blade 7 cooperates with the fixed blade 8 to perform the shearing action. The spring plate 2 provides uniform downward pressure, pressing against the steel shaft 3 and the moving blade holder 6. The steel shaft 3 serves as the main load-bearing element, positioned below the spring plate 2, and precisely positions the distance between the moving blade 7 and the fixed blade 8. The roller 5 is mounted on the moving blade holder 6, forming a cylindrical friction pair with the steel shaft 3. Lubricating cotton 4 continuously releases lubricant to the friction surfaces of the moving blade 7 and the fixed blade 8. The contact area between the steel shaft 3 and the roller 5 is reduced by more than 90% compared to traditional planar friction pairs.

[0050] like Figure 3 As shown, the lubricating cotton 4 adopts a replaceable structure design, which makes it easy for users to replace when the lubricant is exhausted, thus extending the service life of the electric clippers. The lubricating cotton 4 is installed at a specific position on the moving blade holder 6, and releases the lubricant evenly to the friction surface between the moving blade 7 and the fixed blade 8 through capillary action.

[0051] like Figure 4 As shown, the contact surfaces of the moving blade 7 and the fixed blade 8 are equipped with oil reservoirs to store lubricant and reduce friction. These oil reservoirs are distributed in a grid pattern on the contact surfaces of the moving blade 7 and the fixed blade 8, which can effectively store lubricant and distribute it evenly across the entire friction surface during the movement of the moving blade 7. The depth of the oil reservoirs is 0.1-0.3 mm and the width is 0.2-0.5 mm. This size design can store sufficient lubricant without affecting the shearing effect of the moving blade 7 and the fixed blade 8.

[0052] In the operation of this low-friction electric clipper head structure, the motor drives the moving blade holder 6 to reciprocate, and the moving blade holder 6 drives the moving blade 7 to reciprocate relative to the fixed blade 8 to achieve the shearing function. The roller 5 rolls on the steel shaft 3, transforming the traditional planar friction into point-to-line contact rolling friction, which significantly reduces frictional resistance. At the same time, the lubricating cotton 4 continuously releases lubricant to the friction surface between the moving blade 7 and the fixed blade 8. The lubricant is collected in the oil reservoir and evenly distributed, further reducing frictional resistance, reducing the heat generation and energy consumption of the electric clipper, and improving shearing efficiency.

[0053] The design of the spring 2 ensures that appropriate pressure is maintained between the moving blade 7 and the fixed blade 8, which ensures good shearing effect without increasing friction due to excessive pressure. The steel shaft 3, as the main load-bearing shaft, not only bears the downward pressure of the spring 2, but also precisely controls the distance between the moving blade 7 and the fixed blade 8, ensuring the consistency and stability of the shearing effect.

[0054] In a preferred embodiment, the lubricating cotton 4 is made of polyester fiber material, which has good oil absorption and slow-release properties, and can store enough lubricant to maintain a stable release rate during long-term use. The replacement design of the lubricating cotton 4 adopts a snap-on structure. The user can simply press the snap to remove the old lubricating cotton, and to install the new lubricating cotton, simply push it into the slot to secure it. The operation is simple and quick.

[0055] In another preferred embodiment, the oil reservoirs on the contact surfaces of the moving blade 7 and the stationary blade 8 are designed with staggered distribution to ensure that the lubricant can be evenly distributed across the entire friction surface during the reciprocating motion of the moving blade 7. The oil reservoirs are trapezoidal in shape, with the bottom width being smaller than the top width. This design facilitates the storage and release of lubricant and prevents the lubricant from being lost too quickly during use.

[0056] Through the above structural design, this low-friction electric clipper head structure achieves a significant reduction in frictional resistance, reduces the heat generation and energy consumption of the electric clipper, extends the service life of the electric clipper, and improves cutting efficiency and user experience.

[0057] The above description is merely a preferred embodiment of this utility model, and this utility model is not limited to the above embodiments. It is understood that other improvements and variations that are directly derived or conceived by those skilled in the art without departing from the spirit and concept of this utility model should be considered to be included within the protection scope of this utility model.
