Description

Technical Field

[0001] This utility model relates to the field of electric clipper technology, specifically to an electric clipper that is easy to assemble and disassemble. Background Technology

[0002] Electric hair clippers, a common hair-cutting tool, are widely used in home haircuts and professional barbershops. They are powered by a power supply unit, which drives the blades of the working unit to rotate at high speed to achieve the hair-cutting function. As users' requirements for the convenience and maintainability of tools continue to increase, the structural design of electric hair clippers has gradually become a key factor affecting the user experience.

[0003] Currently, electric hair clippers on the market employ various design methods for the connection structure between the power supply unit and the working unit: some products use an integrated structure, where the power supply unit and the working unit are fixedly connected and cannot be separated. While this design ensures connection stability, when the working unit (especially the blade) experiences wear, blockage, or malfunction, the entire unit must be disassembled for repair. This is not only cumbersome but may also damage other components due to the complex disassembly process, increasing maintenance costs. Other products use a detachable structure with screw fixing or simple snap-fit ​​connections. Screw fixing requires tools (such as screwdrivers) for disassembly and assembly, resulting in low operational efficiency, and repeated disassembly and assembly can easily lead to stripped screws, affecting connection reliability. Simple snap-fit ​​connections, while tool-free, are prone to elastic failure after long-term use or frequent disassembly and assembly, leading to loosening of the connection between the power supply unit and the working unit, or even separation during use, posing a safety hazard.

[0004] Furthermore, existing detachable electric hair clippers often lack clear operating instructions and limit designs, making it difficult for users to quickly determine the connection status during installation or disassembly. Improper rotation angles can easily lead to component jamming or poor electrical contact, further reducing ease of use. Therefore, developing an electric hair clipper that is easy to assemble and disassemble, has a stable connection, is intuitive to operate, and has low maintenance costs has become an urgent need in the industry. Utility Model Content

[0005] In view of the above, the purpose of this utility model is to provide an electric clipper that is easy to assemble and disassemble, in response to the problems mentioned in the background art.

[0006] This solution provides an easy-to-assemble and disassemble electric hair clipper, comprising a power supply unit and a working unit, which are electrically connected. It also includes a connecting sleeve disposed between the power supply unit and the working unit, rotatably mounted on the power supply unit. The inner wall of the connecting sleeve near the working unit has a push-in groove and a limiting groove, which are interconnected and form an L-shape. The working unit near the power supply unit has a connecting part, the outer diameter of which matches the inner diameter of the connecting sleeve. The connecting part has a locking block; the locking block is controlled to slide into the push-in groove, and then the connecting sleeve is rotated to embed the locking block in the limiting groove, thus fixing the power supply unit and the working unit together.

[0007] Furthermore, a rotating groove is provided on the side of the power supply unit near the working unit, and a rotating ring corresponding to the rotating groove is provided on the connecting sleeve. The rotating ring fits into the rotating groove, and the connecting sleeve rotates on the power supply unit along the rotating groove.

[0008] Furthermore, a rotation limiting member is provided in the rotation groove, and a limiting member notch is provided on the rotation ring, with the rotation limiting member located within the limiting member notch.

[0009] Furthermore, the length of the notch in the limiting member is greater than or equal to the length of the limiting groove.

[0010] Furthermore, the inner wall of the connecting sleeve is provided with multiple limiting grooves, and the connecting part is provided with multiple fitting blocks corresponding to the limiting grooves.

[0011] Furthermore, multiple limiting grooves are arranged at equal intervals on the inner sidewall of the connecting sleeve.

[0012] Furthermore, a locking arc is provided in the limiting groove, and a locking groove is provided on the mating block to fit the locking arc.

[0013] Furthermore, a locking mark is provided on the connecting sleeve.

[0014] Furthermore, the outer periphery of the connecting sleeve is provided with anti-slip texture.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This solution uses a connecting sleeve between the power supply unit and the working unit. When the power supply unit and the working unit need to be connected, first slide the mating block on the working unit into the push-in groove, and then rotate the connecting sleeve to make the mating block embedded in the limiting groove. When the power supply unit and the working unit need to be disassembled, rotate the connecting sleeve in the opposite direction to make the mating block disengage from the limiting groove, and then separate the power supply unit and the working unit to make the mating block detach from the push-in groove. Compared with the transmission assembly method, this solution has a simpler and more stable structure, and can be more convenient for disassembly and assembly operations.

[0017] 2. This solution includes a rotation limiting component within the rotating groove, and a notch for the limiting component on the rotating ring. The rotation limiting component is positioned within this notch. The rotation limiting component and the notch cooperate to limit the rotation angle of the connecting sleeve, allowing the user to quickly locate the interface of the connecting sleeve and install the power supply unit and the working unit. The length of the notch is greater than or equal to the length of the limiting groove, ensuring that the connecting sleeve has a sufficient rotation angle to lock the power supply unit and the working unit.

[0018] 3. In this solution, multiple limiting grooves are provided around the inner sidewall of the connecting sleeve, and multiple matching blocks corresponding to the limiting grooves are provided on the connecting part, thereby improving the connection strength between the power supply unit and the working unit. On this basis, the multiple limiting grooves are equally spaced on the inner sidewall of the connecting sleeve, thereby ensuring the uniformity of force when the power supply unit and the working unit are connected.

The outer diameter of the connecting part 21 is matched with the inner diameter of the connecting sleeve 3. The connecting part 21 is provided with a fitting block 22. When it is necessary to connect the power supply unit 1 and the working unit 2, the fitting block 22 on the working unit 2 is first slid into the push-in groove 31, and then the connecting sleeve 3 is rotated to make the fitting block 22 embedded in the limiting groove 32. When it is necessary to disassemble the power supply unit 1 and the working unit 2, the connecting sleeve 3 is rotated in the opposite direction to make the fitting block 22 disengage from the limiting groove 32, and then the power supply unit 1 and the working unit 2 are separated to make the fitting block 22 disengage from the push-in groove 31.

[0027] In some embodiments, a rotating groove 11 is provided on the side of the power supply unit 1 near the working unit 2, and a rotating ring 33 corresponding to the rotating groove 11 is provided on the connecting sleeve 3. The rotating ring 33 fits into the rotating groove 11, and the connecting sleeve 3 rotates on the power supply unit 1 along the rotating groove 11. The mutual cooperation between the rotating ring 33 and the rotating groove 11 enables the connecting sleeve 3 to rotate stably on the power supply unit 1.

[0028] In some embodiments, a rotation limiting member 111 is provided in the rotating groove 11, and a limiting member notch 331 is provided on the rotating ring 33. The rotation limiting member 111 is located in the limiting member notch 331. The rotation limiting member 111 and the limiting member notch 331 cooperate with each other to limit the rotation angle of the connecting sleeve 3, so that the user can quickly find the interface of the connecting sleeve 3 and install the power supply unit 1 and the working unit 2. The length of the limiting member notch 331 is greater than or equal to the length of the limiting groove 32, thereby ensuring that the connecting sleeve 3 has a sufficient rotation angle to lock the power supply unit 1 and the working unit 2.

[0029] In some embodiments, the inner sidewall of the connecting sleeve 3 is provided with a plurality of limiting grooves 32, and the connecting part 21 is provided with a plurality of fitting blocks 22 corresponding to the limiting grooves 32, thereby improving the connection strength between the power supply unit 1 and the working unit 2. On this basis, the plurality of limiting grooves 32 are equally spaced on the inner sidewall of the connecting sleeve 3, thereby ensuring the uniformity of force when the power supply unit 1 and the working unit 2 are connected.

[0030] In some embodiments, a locking arc 321 is provided in the limiting groove 32, and a locking groove 221 that fits the locking arc 321 is provided on the mating block 22. The locking arc 321 and the locking groove 221 cooperate with each other to limit the direction angle of the connecting sleeve 3, thereby preventing the connecting sleeve 3 from accidentally rotating and causing the power supply unit 1 and the working unit 2 to separate.

[0031] In some embodiments, the connecting sleeve 3 is provided with a locking mark 34 so that the staff can observe the locked or unlocked state of the connecting sleeve 3 and help the user understand the operation method when seeing the device for the first time.

[0032] In some embodiments, the outer periphery of the connecting sleeve 3 is provided with anti-slip texture to improve the ease of operation of the connecting sleeve 3 and prevent the user from detaching it when operating the electric clipper.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
