Description

Technical Field

[0001] This utility model relates to the field of hair clippers, and in particular to a hair clipper with a shock absorption mechanism. Background Technology

[0002] Hair clippers, widely used in daily life, are frequently used in various settings such as homes and barbershops due to their convenient and efficient hair cutting performance. They are an important tool for maintaining personal appearance and hair care. Their core structure mainly includes a cutting head for cutting and a drive assembly that provides power for the head's movement. The cutting head consists of a fixed blade and a moving blade that work together. The fixed blade is fixed to form a cutting reference, while the moving blade can move relative to the fixed blade. The relative movement between the two achieves the cutting operation on the hair.

[0003] In the power transmission process of the drive component, the motor is usually used as the power source. The output shaft of the motor is connected to the eccentric wheel. When the motor starts, the motor drives the eccentric wheel to rotate in a circle. During the rotation, the eccentric wheel drives the moving blade to reciprocate through the transmission structure, so that the moving blade and the fixed blade produce continuous relative movement, thereby achieving a stable hair cutting effect.

[0004] However, in practical applications of existing technology, there are significant technical drawbacks when using an external motor to drive hair clippers. The structural characteristics of an external motor mean that its rotating core rotates synchronously with the motor, while the eccentric wheel itself rotates at high speed during operation. The combined rotational actions of these two components result in a significant "tail-wagging effect" at the end of the external motor. This tail-wagging effect causes substantial vibration in the entire motor, which is transmitted through the drive components to the clipper body and blades, ultimately causing noticeable vibration throughout the clippers. Users will clearly feel the discomfort caused by this vibration when holding and using the clippers, severely affecting the user experience. This not only reduces the stability of haircutting operations but may also increase hand fatigue due to prolonged holding of vibrating clippers, negatively impacting the user experience and operational effectiveness of the hair clippers. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a hair clipper with a shock-absorbing mechanism that has a better shock absorption effect.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is a hair clipper with a shock-absorbing mechanism, including a blade head, a drive assembly, and a housing. The blade head includes a fixed blade and a moving blade. The drive assembly includes an external rotating motor and an eccentric wheel. The forward output shaft of the external rotating motor is connected to the eccentric wheel, and the eccentric wheel drives the blade to move. The external rotating motor includes a fixed core and a rotating core. A fixing plate is provided inside the housing, and the fixing plate and the fixing core are fixed to each other. The external rotating motor is characterized by having a reverse output shaft, which is a reverse extension of the forward output shaft and extends through the bottom housing of the external rotating motor. A fixing frame is provided inside the housing, and a fixing hole is provided on the fixing frame. The reverse output shaft is inserted into the fixing hole. The fixing frame and the reverse output shaft constitute the shock-absorbing mechanism.

[0007] A further preferred embodiment of this utility model is: a fixing plate is provided between the fixing core and the fixing piece, the fixing core is provided with screw holes, the fixing plate is provided with insertion holes, the fixing plate and the fixing core are fixed by screws, and the fixing plate and the fixing piece are fixed together.

[0008] A further preferred embodiment of this utility model is that the forward output shaft and the reverse output shaft are integrally formed, thus creating a complete output shaft.

[0009] A further preferred embodiment of this utility model is as follows: the fixing frame includes a first support member, a second support member, and a fixing block, the fixing block is disposed above the first support member and the second support member, and the first support member and the second support member are connected to the housing.

[0010] A further preferred embodiment of this utility model is that the fixing hole is provided on the fixing block.

[0011] A further preferred embodiment of this utility model is that the first support member and the second support member are connected by screws respectively.

[0012] A further preferred embodiment of this utility model is: the fixing block includes a transverse fixing member, a protrusion is provided below the transverse fixing member, and a fixing hole is provided on the protrusion.

[0013] A further preferred embodiment of this utility model is as follows: the rotating core includes a shell and a coil, the coil is disposed inside the shell, and a circuit board is disposed on one side of the fixed core.

[0014] A further preferred embodiment of this utility model includes a control circuit, a battery, a charging port, and a control button. The battery supplies power to the external rotating motor, and the control button controls the battery discharge intensity and discharge time through the control circuit.

[0015] This invention creates a bidirectional support shock-absorbing mechanism by adding a reverse output shaft to the external motor and inserting it into the fixing hole of the inner frame of the housing. This structure effectively counteracts the centrifugal force generated by the superimposed rotation of the external motor's rotating core and the eccentric wheel, fundamentally suppressing the "tail-wagging effect" at the motor's tail end and significantly reducing the overall vibration amplitude of the motor. Simultaneously, the cooperation between the reverse output shaft and the fixing frame also provides stable positioning for the motor, preventing it from shifting during operation, further reducing the transmission of vibration to the machine body and blades, significantly improving the user's grip on the clippers, reducing hand fatigue, and ensuring the stability and precision of haircutting operations.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0020] like Figures 1-3 As shown, a hair clipper with a shock-absorbing mechanism includes a blade head 1, a drive assembly, and a housing 2. The blade head 1 includes a fixed blade 3 and a moving blade 4. The drive assembly includes an external motor 5 and an eccentric wheel 6. The forward output shaft 7 of the external motor 5 is connected to the eccentric wheel 6, and the eccentric wheel 6 drives the blade 4 to move. The external motor 5 includes a fixed core 8 and a rotating core 9. A fixing plate 10 is provided inside the housing 2, and the fixing plate 10 and the fixed core 8 are fixed to each other. The external motor 5 is provided with a reverse output shaft 11, which is a reverse extension of the forward output shaft 7 and extends through the housing 12 at the bottom of the external motor. A fixing frame 13 is provided inside the housing 2, and a fixing hole 14 is provided on the fixing frame 13. The reverse output shaft 11 is inserted into the fixing hole 14. The fixing frame 13 and the reverse output shaft 11 constitute the shock-absorbing mechanism. By adding a reverse output shaft 11 to the external motor 5 and inserting the reverse output shaft 11 into the fixing hole 14 of the fixing frame 13 inside the housing 2, a bidirectional support shock-absorbing mechanism is formed. This structure effectively counteracts the centrifugal force generated by the combined rotation of the rotating core 9 and eccentric wheel 6 of the external motor 5, fundamentally suppressing the "tail-wagging effect" at the tail end of the external motor 5 and significantly reducing the overall vibration amplitude of the motor. Simultaneously, the cooperation between the reverse output shaft 11 and the fixing bracket 13 also provides a stabilizing and limiting effect on the motor, preventing it from shifting during operation. This further reduces the transmission of vibration to the body and blade 1, significantly improving the user's grip on the clippers, reducing hand fatigue, and ensuring the stability and precision of haircutting operations.

[0021] A fixing plate 30 is provided between the fixing core 8 and the fixing plate 10. The fixing core 8 has screw holes, and the fixing plate 30 has insertion holes. The fixing plate 30 and the fixing core 8 are fixed with screws, and the fixing plate 30 and the fixing plate 10 are fixed together. The fixing method of passing screws through the insertion holes of the fixing plate 30 and screwing them into the screw holes of the fixing core 8 achieves a firm connection between the fixing plate 30 and the fixing core 8. This detachable rigid connection structure not only ensures the positional stability of the fixing core 8 within the housing 2 and avoids additional vibration during motor operation due to loose fixing, but also facilitates future maintenance or replacement of the motor.

[0022] The forward output shaft 7 and the reverse output shaft 11 are integrated into one piece, forming a complete output shaft. This integrated design gives the output shaft structure of the external motor 5 greater integrity and strength. The one-piece molding structure avoids gaps or loosening issues that may occur at the connection points of separate shafts, ensuring that the output shaft maintains coaxiality during high-speed rotation and reducing additional vibration caused by shaft wobble.

[0023] The mounting frame 13 includes a first support member 15, a second support member 16, and a fixing block 17. The fixing block 17 is positioned above the first support member 15 and the second support member 16, which connect to the housing 2. The mounting frame 13 is connected to the housing 2 via the first support member 15 and the second support member 16, and the fixing block 17 is positioned above both, forming a stable frame-type support structure. The symmetrical distribution or reasonable layout of the first support member 15 and the second support member 16 can evenly distribute the motor vibration load borne by the fixing block 17, avoid local stress concentration that could lead to deformation of the mounting frame 13, and ensure the stability of the mounting frame 13 in supporting the reverse output shaft 11.

[0024] The fixing hole 14 is provided on the fixing block 17. Positioning the fixing hole 14 on the fixing block 17 places it at the core support position of the fixing frame 13, allowing for more stable support after the reverse output shaft 11 is inserted. The fixing block 17, serving as the connecting carrier between the first support member 15 and the second support member 16, has high structural strength and can effectively resist the vibration and impact forces transmitted by the reverse output shaft 11.

[0025] The first support member 15 and the second support member 16 are connected to the housing 2 by screws. This screw connection between the first support member 15, the second support member 16, and the housing 2 achieves a secure and detachable connection between the fixing frame 13 and the housing 2. This detachable connection facilitates future maintenance and replacement of the fixing frame 13 or the shock absorption mechanism.

[0026] The fixing block 17 includes a transverse fixing member 18, with a protrusion 19 below the transverse fixing member 18 and a fixing hole 14 disposed on the protrusion 19. The protrusion 19 below the transverse fixing member 18 and the fixing hole 14 disposed on the protrusion 19 provide a more reasonable installation height and position for the fixing hole 14. The structure of the protrusion 19 allows the reverse output shaft 11 to maintain an appropriate distance from the bottom housing 12 of the motor after being inserted into the fixing hole 14, preventing friction or collision between the motor housing and the fixing block 17, and reducing additional noise and vibration.

[0027] The rotating core 9 includes a housing and a coil, with the coil housed inside the housing. A circuit board 20 is located on one side of the fixed core 8. By placing the coil inside the housing of the rotating core 9 and providing the circuit board 20 on the fixed core 8 side, the internal structural layout of the external rotating motor 5 is optimized. The circuit board 20 on the fixed core 8 side has a compact layout, facilitating electrical connection with internal motor components.

[0028] This invention also includes a control circuit 21, a battery 22, a charging port 23, and a control button 24. The battery 22 supplies power to the external motor 5, and the control button 24 controls the discharge intensity and discharge time of the battery 22 through the control circuit 21. Through the cooperation of the control circuit 21, battery 22, charging port 23, and control button 24, precise control of the discharge intensity and discharge time of the battery 22 is achieved. Users can adjust the motor speed using the control button 24, allowing them to select the appropriate cutting speed according to different hair materials and hairdressing needs, and further reduce vibration and noise during motor operation in low-speed mode, improving user comfort.
