Low-vibration electric clipper

Abstract

The application relates to a low-vibration electric clipper, which is provided with a damping assembly in a shell of the electric clipper. When the shell is vibrated due to the work of a driving assembly, the damping assembly generates a force opposite to the vibration direction of the electric clipper to weaken the vibration of the electric clipper and reduce the vibration effect of the electric clipper during work. A cutter head assembly is detachably connected with the shell through buckling pieces, so that the cutter head assembly can be conveniently replaced. A pushing piece arranged on the cutter head assembly can conveniently adjust the distance between a moving blade and a fixed blade, change the hair cutting length, and better adjust the hand feeling by matching the gear blocks and the gear grooves.

Technical Field

[0001] This application relates to the field of electric clippers, and more particularly to a low-vibration electric clipper. Background Technology

[0002] Electric hair clippers, a common hair styling and cutting tool, consist of a core component including a drive motor, transmission mechanism, and cutting blades. As users' demands for a better user experience increase, existing electric hair clippers have revealed the following significant drawbacks after long-term use: excessive vibration intensity, affecting the user experience. Traditional electric hair clippers mostly use DC motors to directly drive the blades in reciprocating motion. The centrifugal force generated by the high-speed rotation of the motor is transmitted to the outer casing, causing continuous high-frequency vibration of the machine. Especially in high-power operating mode, the vibration amplitude can reach 30-40 decibels, causing not only hand fatigue but also reducing cutting precision (especially when handling intricate hairstyles), and easily leading to muscle soreness with prolonged use. Furthermore, the strong vibration can cause unstable contact between the blades and the skin, increasing the risk of accidental injury. Existing technologies often use rubber pads or shock-absorbing springs to reduce vibration, but this sacrifices structural compactness and has limited effectiveness in suppressing high-frequency vibration.

[0003] Therefore, there is an urgent need for a low-vibration electric clipper structure design that can improve user experience and safety while ensuring cutting efficiency. Utility Model Content

[0004] The technical problem this application aims to solve is that existing electric hair clippers exhibit excessive vibration, negatively impacting the user experience. To address these shortcomings of the prior art, this application provides a low-vibration electric hair clipper.

[0005] To solve the above-mentioned technical problems, the technical solution adopted in this application is:

[0007] Preferably, the shock absorption assembly includes a shock absorption bracket connected to the housing. One end of the shock absorption bracket is fixedly connected to the housing, and the other end is connected to a shock absorption block. The shock absorption block generates a force in the opposite direction to the vibration direction of the electric clipper to reduce the vibration of the electric clipper.

[0008] Preferably, the drive assembly includes a motor and an eccentric wheel connected to and rotating synchronously and coaxially with the motor shaft. An eccentric column is provided on the eccentric wheel. The eccentric column rotates around the motor shaft as the center. The eccentric wheel drives the driving blade to move to achieve hair cutting.

[0009] Preferably, the cutter head assembly is provided with a fastening element, the fastening element includes a first fastening end, and a second fastening end is provided on the moving cutter seat corresponding to the first fastening end. The first fastening end and the second fastening end are in contact.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this application. Obviously, the described embodiments are some embodiments of this application, but not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application.

[0024] A preferred embodiment of this application provides a low-vibration electric clipper; such as Figures 1-3 As shown, the device includes a housing 10 and a blade assembly 20 connected to one end of the housing. The housing includes an upper housing 101 and a lower housing 100, which are fastened together by screws. A drive assembly 40, a control board 109, and a battery 108 are housed within the upper and lower housings. The control board controls the operation of the drive assembly. The lower housing 100 also has a power switch 103 and a mode button 104 connected to the control board. The power switch turns the clippers on or off, and the mode button adjusts the clippers' operating mode. A charging port 105 connected to the control board is located at the other end of the housing, allowing the battery to be charged to extend the clippers' runtime. To prevent battery heating from affecting the control board, EVA foam 107 is provided on the upper and lower sides of the battery, which not only blocks the heat generated by the battery but also provides some shock absorption. Multiple anti-slip grooves 102 are provided on one side of the housing to increase friction when holding the clippers.

[0025] Specifically, such as Figure 3As shown, the drive assembly 40 includes a motor 400 connected to the control assembly. An eccentric wheel 402 is fitted on the motor shaft 401, and the eccentric wheel rotates synchronously with the motor shaft. A through hole is provided on one side of the housing for the motor shaft to pass through, which can achieve the sealing of the main chamber of the housing and also provide a stabilizing effect for the rotation of the motor shaft. An eccentric column 403 is provided on the eccentric wheel. When the motor shaft rotates, the eccentric wheel 402 rotates synchronously with the motor shaft at the same speed, while the eccentric column 403 rotates around the motor shaft as the center. The cutter head assembly 20 includes a fixed blade 200 and a movable blade 201 connected to the fixed blade. The movable blade is connected through a movable blade holder 202. When the eccentric column rotates, it drives the movable blade holder to move left and right, and drives the movable blade 201 to move relative to the fixed blade 200, thereby realizing the hair cutting operation. The cutter head assembly 20 also includes a toggle member 203. A toggle groove 2024 is provided on the movable blade holder 202 corresponding to the toggle member. A rotating column 2022 is provided within the toggle groove. The toggle member rotates around the toggle column, and simultaneously, an abutment end 2031 is provided on the toggle member to abut against the movable blade holder. When the toggle member rotates around the toggle column, the abutment end also rotates synchronously and pushes the movable blade holder up and down, thereby changing the relative distance between the movable blade and the fixed blade to adjust the haircut length. To avoid over-adjustment, a limit post 2023 is also provided within the toggle groove, and a limit groove 2032 is provided on the toggle member corresponding to the limit post. The distance the limit post moves within the limit groove is the moving length of the abutment end, thereby limiting the relative moving length of the movable blade holder and the fixed blade holder. To facilitate tossing and improve the feel of tossing, the contact surface between the tossing element and the tossing groove can be equipped with a shift protrusion and multiple shift grooves. When the tossing handle 2030 is rotated, it drives the shift protrusion into different shift grooves, which indicates different adjustment lengths, making adjustment more convenient and providing a better feel during adjustment.

[0026] Furthermore, such as Figures 1-7As shown, to facilitate the disassembly of the cutter head assembly, a fastening member 50 for connecting to the housing is provided in the cutter head cavity. The fastening member includes a fixing hole 500 connected to the partition plate by screws, and a first fastening end 501. A second fastening end 2020 is provided below the moving cutter seat corresponding to the first fastening end 501. At the same time, a fastening hole 110 is provided in the cutter head cavity, and a fastening block 2021 is provided on the cutter head assembly corresponding to the fastening hole. When the cutter head assembly needs to be connected to the housing, the fastening block is first inserted into the fastening hole, and then the cutter head assembly is pressed until the first fastening end and the second fastening end are fastened together to install the cutter head assembly. When disassembly is required, a pushing force is applied from the moving blade side of the cutter head assembly to separate the first fastening end and the second fastening end, and then the cutter head assembly is removed from the housing. To reduce the vibration transmitted from the motor rotation to the housing, a shock-absorbing assembly 60 is installed inside the cavity. This assembly includes two sets of shock-absorbing brackets 601 connected to the fastening member 50, with a shock-absorbing block 600 connected between them. The shock-absorbing block is suspended by the brackets. When the motor rotates and causes the electric clipper housing to shake, the shock-absorbing block will remain stationary initially due to its presence. When the electric clipper shows a tendency to shake to the left, the shock-absorbing block moves to the right due to inertia, thus reducing the leftward movement of the electric clipper. The amplitude of the electric clipper's movement is such that when the clipper swings to the right, the damping block moves to the left due to inertia, reducing the amplitude of the clipper's rightward movement. When the motor operates, it causes the clipper to swing, and the damping block moves in the opposite direction to the clipper's swing to reduce the amplitude of the clipper's swing, thus achieving the shock absorption effect of the clipper. This is similar to the effect of installing a damper in a high-rise building. When the clipper housing vibrates under the action of the motor, the damping block generates a force in the opposite direction to the clipper's vibration to slow down the clipper's vibration.

[0027] Turn on the electric hair clippers using the power switch 103, then press the mode button 104 to select the working mode and rotate the motor 400. The motor rotation drives the eccentric wheel 402 and the eccentric column 403 to rotate, which in turn moves the moving blade holder and moving blade 201 left and right, achieving hair cutting through the moving and fixed blades. Simultaneously, the motor causes the hair clipper housing to vibrate, and the damping block generates a force in the opposite direction to the vibration of the housing, thus reducing the vibration effect of the hair clippers. When it is necessary to replace the blade assembly, apply a pushing force to the moving blade 201 to separate the first locking end 501 and the second locking end 2020. Then, remove the locking block 2021 from the locking hole 110. Insert the locking block of the replaced blade assembly into the locking hole and press the blade assembly to lock the first and second locking ends together, thus completing the installation of the blade assembly. When it is necessary to adjust the cutting length of the moving blade and the fixed blade, a rotational force is applied to the toggle handle 2030 to make the toggle member rotate around the rotating column 2022 as the center, and drive the abutment end 2031 to move up and down, which in turn pushes the moving blade seat to move, and drives the moving blade to move, thereby realizing the adjustment of the blade length. At the same time, the position protrusion can be engaged in different position slots to indicate that the adjusted length is fixed, making the adjustment more convenient. At the same time, it is easier to know the current extension length during the adjustment, making the operation more convenient.

Furthermore, based on the teachings of this application, these features and embodiments can be modified to suit specific circumstances and materials without departing from the spirit and scope of this application.
