Description

Technical Field

[0001] This utility model belongs to the field of daily necessities, specifically relating to a two-finger gripping single-hand hair care device. Background Technology

[0002] Currently, hair care devices are mainly household products used to trim or tidy up hair or beards, such as hair clippers, razors, and hair removal devices.

[0003] However, with the increasing demand for portability, hair removal devices have become smaller and smaller. Therefore, during use, it is necessary to use the thumb and other fingers to pinch the device and remove hair. This method of operation has the following technical drawbacks:

[0004] 1) An unstable grip may result in insufficient contact between the shaving head and the skin, requiring repeated shaving of the same area, prolonging shaving time, and the shaving head may not conform to the facial contours (such as the chin and neck), resulting in an incomplete shave and low shaving efficiency.

[0005] 2) When the hand shakes, the razor head may deviate from the expected path, especially at joints or concave and convex areas (such as the Adam's apple), which can easily cause scratches. At the same time, stable operation may increase the friction between the blade and the skin, causing redness or folliculitis. In addition, the razor is easy to slip when not held firmly, which shortens the life of the razor and increases the risk of accidental injury caused by the product slipping (such as in a bathroom environment, where it may fall and injure the foot). At the same time, an unstable hand may increase the abnormal friction between the blade and the skin, accelerating the dulling of the blade.

[0006] 3) Users need to grip the small body tightly, which can easily lead to hand muscle soreness after prolonged use. At the same time, it is difficult to adjust the shaving angle when holding it with one hand, resulting in a poor user experience. Utility Model Content

[0007] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an improved two-finger gripping single-hand hair care device.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0009] A two-finger gripping single-handed hair care device includes a device body, a blade assembly formed at one end of the device body, and a finger grip portion disposed at the opposite end of the blade assembly and capable of extending outward or retracting onto the device body. When the finger grip portion extends outward, a first finger groove and a second finger groove are formed between the finger grip portion and the device body, which are relatively separated. Two fingers pass through the first finger groove and the second finger groove respectively to form a grip, and the remaining fingers abut against the periphery of the device body to form a single-handed grip with the blade assembly facing outward.

[0010] According to a specific embodiment and preferred aspect of this utility model, the finger-clamping part includes a first finger-clamping body and a second finger-clamping body respectively rotatably mounted on the end of the device body. The first and second finger-clamping bodies act as a barrier, and a first and second finger groove are formed between the device body, the first finger-clamping body, and the second finger-clamping body. A two-finger insertion clamping mechanism is formed based on the two finger-clamping bodies, thus enabling the device body to be gripped.

[0011] Preferably, the first and second finger-clamping bodies are installed at the ends of the device body in a synchronously rotating manner. This synchronous rotation of the two finger-clamping bodies improves ease of operation.

[0012] According to another specific embodiment and preferred aspect of this utility model, a notch mounting groove is formed at the end of the device body. A first finger-clamping body and a second finger-clamping body are symmetrically installed within the notch mounting groove at the end of the device body. Both the first and second finger-clamping bodies include a wheel disk rotatably mounted within the device body and wheel arms formed on the wheel disks. The two wheel disks are in contact, and the two wheel arms rotate outwards and fold inwards synchronously with the wheel disks. Based on the notch mounting groove design, the first and second finger-clamping bodies are effectively arranged.

[0013] Preferably, the wheel is a gear wheel, and the two gear wheels mesh with each other. This prevents slippage during synchronous movement.

[0014] In some specific implementations and preferred aspects, the wheel arm includes a fitting arm and a curved arm, wherein when the finger buckle is extended outward, the fitting arm is relatively fitted, and the curved arm extends to both sides of the fitting part, and the two curved arms and the end of the device body form the first finger groove and the second finger groove; when the finger buckle is retracted inward, the two curved arms retract to both sides of the end of the device body.

[0015] Preferably, the first and second finger grooves open from opposite sides of the fitting portion, and the open ends of the curved arm are inserted into both sides of the end of the device body when retracted. This open portion allows for the insertion and gripping of fingers of different sizes, and the operation is very convenient, without any operational obstacles, thus improving the user experience.

[0016] Furthermore, the notch mounting groove forms a snap-fit ​​part from the groove end, and the open end of each curved arm matches and inserts into the snap-fit ​​part, with the arm and curved arm concealed within the notch mounting groove. Based on snap-fit ​​assembly and disassembly, the accidental overturning rate of the wheel arm is reduced.

[0017] Furthermore, the notch mounting slot is equipped with arched support sections that correspond one-to-one with the wheel arm. When the wheel arm retracts, it adheres to the arched support section from the inner wall. This combination of snap-fit ​​assembly and disassembly, along with the inner wall support, reduces the probability of accidental deformation of the bending arm and increases its service life.

[0018] In addition, the wheel arm fits snugly against the arched support and fills the notches on both sides of the mounting groove. This not only enhances the overall aesthetics but also facilitates the operation of snapping the wheel arm up.

[0019] In some specific embodiments, the cutter head assembly includes multiple cutters arranged side by side.

[0020] Meanwhile, a charging port is also provided on the arched support; the hair trimmer is similar in shape to the wireless earphone case, which is not only small and portable, but also aesthetically pleasing.

[0021] Due to the implementation of the above technical solution, this utility model has the following advantages compared with the prior art:

[0022] Existing hair care devices suffer from several drawbacks. First, an unstable grip can lead to insufficient contact between the shaving head and the skin, requiring repeated shaving of the same area, prolonging shaving time, and the shaving head struggles to conform to facial contours (such as the chin and neck), resulting in an incomplete shave and low shaving efficiency. Second, hand movement can cause the shaving head to deviate from its intended path, especially on joints or uneven areas (such as the Adam's apple), easily causing cuts. Stable operation can also increase friction between the blades and the skin, leading to redness or folliculitis. Furthermore, an unstable grip can cause the razor to slip, shortening its lifespan and increasing the risk of accidental injury (such as in a bathroom where a slip could injure a foot). Unstable handling can also exacerbate abnormal friction between the blades and the skin, accelerating blade dulling. Third, users need to grip the small device tightly, which can lead to hand muscle soreness after prolonged use. Adjusting the shaving angle with one hand is also difficult, resulting in a subpar user experience. This invention addresses these shortcomings by redesigning the hair care device from the ground up, cleverly solving these problems. To address the shortcomings and defects of traditional techniques, this hair removal device utilizes an outward-spreading finger grip to create a first and second finger groove that are relatively separated from the device body. Two fingers then pass through these grooves to form a clamping grip, while the remaining fingers press against the periphery of the device body, creating an outward-facing blade assembly for single-handed hair removal. This allows for one-handed, skin-hugging hair removal. Therefore, this invention offers several advantages: firstly, the two-finger grip, combined with the remaining fingers, securely holds the device within the palm of the hand, ensuring the blade assembly adheres evenly to the skin for hair removal, eliminating the safety hazards caused by blade instability; secondly, it offers flexible operation, and the two finger grooves allow for use regardless of hand size, providing a stable one-handed grip with a very low probability of accidental drop. Furthermore, the fully extended grip prevents hand muscle soreness and enhances user comfort. Additionally, the dual-finger groove design further enhances the overall aesthetic appeal of the device.

[0040] like Figures 1 to 8 As shown, the two-finger gripping single-handed hair care device of this embodiment includes a device body 1, a blade assembly 2 formed at one end of the device body 1, and a finger gripping part 3 disposed at the opposite end of the blade assembly 2 and capable of being extended outward or retracted on the device body. When the finger gripping part 3 is extended outward, a first finger groove c1 and a second finger groove c2 are formed between the finger gripping part 3 and the device body 1, which are relatively separated. Two fingers pass through the first finger groove c1 and the second finger groove c2 respectively to form a gripping action, and the remaining fingers abut against the periphery of the device body 1 to form a single-handed gripping action with the blade assembly 2 facing outward.

[0041] Specifically, a notch mounting groove 10 is formed at the end of the device body 1. The finger-clamping part 3 includes a first finger-clamping body 31 and a second finger-clamping body 32, which are respectively rotatably mounted inside the notch mounting groove 10. The first finger-clamping body 31 and the second finger-clamping body 32 form a first finger groove c1 and a second finger groove c2 based on the contact barrier between the device body 1, the first finger-clamping body 31, and the second finger-clamping body 32. The two finger-clamping bodies form a two-finger insertion clamping mechanism, thereby completing the gripping of the device body.

[0042] In some specific embodiments, the first finger-clamp body 31 and the second finger-clamp body 32 are symmetrically installed, and the first finger-clamp body 31 and the second finger-clamp body 32 are synchronously flipped and installed at the end of the device body 1. The synchronous flipping of the two finger-clamp bodies improves the ease of operation.

[0043] Both the first finger-clamping body 31 and the second finger-clamping body 32 include a wheel a rotatably mounted inside the device body 1 and a wheel arm b formed on the wheel a. The two wheel a are in contact, and the two wheel arms b rotate outward and fold inward synchronously with the wheel a. Based on the design of the notch mounting groove, the first finger-clamping body and the second finger-clamping body are effectively arranged.

[0044] In this example, wheel a is a gear wheel, and the two gear wheels mesh with each other to prevent slippage during synchronous movement. Wheel arm b includes a contact arm b1 and a curved arm b2. When the finger buckle 3 extends outward, the contact arm b1 is relatively close to the contact part, and the curved arm b2 extends to both sides of the contact part. The two curved arms b2 and the end of the device body 1 form the first finger groove c1 and the second finger groove c2. When the finger buckle is retracted, the two curved arms retract inward to both sides of the end of the device body.

[0045] Furthermore, the first finger groove c1 and the second finger groove c2 open from opposite sides of the fitting portion, and the open ends of the curved arm b2 are inserted into both sides of the end of the device body 1 when retracted. This open portion allows for the insertion and gripping of fingers of different sizes, and operation is very convenient without any operational obstacles, improving the user experience. Simultaneously, the notch mounting groove 10 forms a snap-fit ​​portion 100 from its opening end, and the open ends b20 of each curved arm b2 are matched and inserted into the snap-fit ​​portion 100, with the fitting arm b1 and the curved arm b2 concealed within the notch mounting groove 10. Based on the snap-fit ​​assembly and disassembly, the accidental overturning rate of the wheel arm is reduced.

[0046] Furthermore, an arched support portion 101 corresponding to the wheel arm b is provided within the notch mounting groove 10. When the wheel arm b is retracted, it adheres to the arched support portion 101 from its inner wall. This combination of snap-fit ​​and support within the inner wall reduces the probability of accidental deformation of the bending arm, increasing its service life. Simultaneously, the wheel arm b adheres to the arched support portion 101 and fills the notch mounting grooves 10 on both sides. This not only enhances the overall aesthetics but also facilitates the wheel arm snap-fit ​​operation.

[0047] In some specific embodiments, the blade assembly 2 includes multiple blades 20 arranged side by side, and a charging interface is also provided on the arched support 101; the hair care device is similar in shape to the wireless earphone case, and is not only small and easy to carry, but also aesthetically pleasing.

[0048] In summary, by operating the outward extension of the finger grip, a first and second finger groove are formed between the finger grip and the device body. Two fingers then pass through the first and second finger grooves to form a clamping grip, and the remaining fingers press against the periphery of the device body to form a single-handed grip with the blade assembly facing outwards. This allows for one-handed hair removal close to the skin. Therefore, this invention, on the one hand, based on the two-finger grip and the gripping of the remaining fingers, firmly places the device body within the palm of the hand, allowing the blade assembly to fit relatively evenly against the skin for hair removal, thus eliminating the safety risks caused by blade instability during hair removal. On the one hand, it is easy to use and flexible in operation. Based on the design of two finger slots, its use is not limited by hand size, and it is stable when gripped with one hand, with a very low probability of accidental drop. At the same time, the full extension of the fingers prevents hand muscle soreness and enhances the user's comfort. Furthermore, the design of the two finger slots further enhances the overall aesthetic appeal of the device. Thirdly, the two finger clips form a two-finger insertion grip, allowing for complete gripping of the device body. Simultaneous rotation of the two finger clips improves ease of operation. Fourthly, the notch-mounted slot design effectively arranges the first and second finger clips. The device features a body with a gear-shaped wheel and two meshing gears to prevent slippage during synchronous movement. Furthermore, when the finger grip extends outwards, the connecting arms are positioned to fit snugly against each other, with the curved arms extending to both sides of the fitting portion. The two curved arms and the end of the device body form the first and second finger grooves. When the finger grip retracts, the two curved arms retract inwards to both sides of the end of the device body. Fifthly, the first and second finger grooves open from opposite sides of the fitting portion, and the open ends of the curved arms, when retracted, are inserted into both sides of the end of the device body. This open portion accommodates the insertion and gripping of fingers of different sizes, and allows for easy operation. It is very easy to operate without any operational obstacles, which increases the operating feel; the sixth aspect is that the buckle assembly and disassembly reduces the accidental overturning rate of the arm, and at the same time as the buckle assembly and disassembly, the inner wall fits and supports, which reduces the probability of accidental deformation of the bending arm and increases the service life; the seventh aspect is that the arm fits into the arched support and fills the notch on both sides of the mounting groove, which not only enhances the overall aesthetics, but also facilitates the operation of buckling the arm; the eighth aspect is that the blade assembly includes multiple blades arranged side by side, and a charging port is also provided on the arched support; the hair care device is similar in shape to the wireless earphone case, which is not only small and easy to carry, but also aesthetically pleasing.

[0049] The present utility model has been described in detail above, with the aim of enabling those skilled in the art to understand its contents and implement it. However, this description should not be construed as limiting the scope of protection of the present utility model. All equivalent changes or modifications made in accordance with the spirit and essence of the present utility model should be included within the scope of protection of the present utility model.
