[0032] like Figures 1 to 3As shown, an embodiment of the present invention provides a beauty device inner shell, including a front shell 1 and a rear shell 2. The front shell 1 includes a button board mounting position 11, a main control board mounting position 12 and a vibration motor mounting position 13. The rear shell 2 includes an RF circuit board mounting position 21 and a battery mounting position 22.

[0033] The front housing 1 and the rear housing 2 are fastened together by the fastening assembly 3. The vibration motor mounting position 13 is located at the upper end of the front housing 1. The keypad mounting position 11, the main control board mounting position 12, the radio frequency circuit board mounting position 21 and the battery mounting position 22 are all located between the front housing 1 and the rear housing 2.

[0034] In this embodiment, a modular layout design for the installation position is adopted. A button panel mounting position 11 and a main control board mounting position 12 are stacked front and rear inside the front housing 1. A vibration motor mounting position 13 is then provided at the upper end of the front housing 1. This divides the internal space of the rear housing 2 into an RF circuit board mounting position 21 and a battery mounting position 22. This allows the button panel, main control board, RF circuit board, and battery to be installed compactly and without interference within the installation space formed after the front housing 1 and rear housing 2 are connected. Furthermore, placing the vibration motor outside the inner housing further improves the positional stability of the internal components, reduces the impact of vibration on the internal components, and the vibration motor closer to the upper electrode head provides better vibration performance. The front housing 1 and rear housing 2 are quickly and reliably detachably connected via a fastening assembly 3, thereby improving installation efficiency.

[0035] In summary, the inner shell of the beauty device provided in this embodiment of the utility model improves the structure by having the front shell 1 and the rear shell 2 fastened together by the fastening assembly 3, and sets the vibration motor mounting position 13 at the upper end of the inner shell. Furthermore, the button plate mounting position 11, the main control board mounting position 12, the radio frequency circuit board mounting position 21, and the battery mounting position 22 are all located inside the inner shell, making the functional components installed inside the inner shell compact. This is beneficial for the miniaturization design of the beauty device and eliminates the need for additional support structures such as button mounting plates, which can significantly simplify the installation and disassembly process, thereby reducing the difficulty of installing, disassembling, inspecting, and maintaining the beauty device.

[0036] In one embodiment, the fastening assembly 3 includes fasteners 31 disposed on the outer periphery of the front housing 1 and retaining rings 32 disposed on the outer periphery of the rear housing 2 that match the fasteners 31. Further, at least three sets of symmetrically arranged fasteners 31 are provided on both sides of the front housing 1, and the number of retaining rings 32 on both sides of the rear housing 2 matches the number of fasteners 31.

[0037] In this embodiment, the fastening structure of the fastener 31 and the retaining ring 32 enables a reliable detachable fastening, ensuring a stable connection between the front housing 1 and the rear housing 2 while meeting the need for quick assembly and disassembly. Since the inner shell of the beauty device has an overall elongated cylindrical structure, at least three pairs of fasteners 31 and retaining rings 32 are provided on both sides of the front housing 1 and the rear housing 2. This structure, with at least three pairs of fastening components 3 on each side, ensures a stable fastening structure, more even force distribution, and prevents damage to any single fastening component 3 from affecting the tightness of the connection between the front housing 1 and the rear housing 2.

[0038] In one embodiment, a plurality of spare connecting components 4 are provided at the connection between the front housing 1 and the rear housing 2. Further, the spare connecting components 4 include a threaded post 41 provided in the front housing 1 and a screw hole 42 provided in the rear housing 2, and the outer periphery of the screw hole 42 is provided with a clearance notch.

[0039] In this embodiment, the threaded post 41 in the spare connecting assembly 4 is aligned with the screw hole 42 and then fixedly connected to the front housing 1 and the rear housing 2 by screws. Even if some of the fastening components 3 are damaged, such as some of the fasteners 31 breaking, they can be quickly re-fixed by screws. If necessary, both the fastener 31 assembly and the spare connecting assembly 4 can be used for fixing at the same time. The composite connection structure can significantly improve the bonding strength between the front housing 1 and the rear housing 2, and can withstand long-term opening and closing tests without loosening, thus meeting the needs of application scenarios with more stringent fastening requirements.

[0040] In one embodiment, the upper end of the front housing 1 is provided with an outwardly extending receiving platform, the vibration motor mounting position 13 is provided on the upper surface of the receiving platform, and the lower surface of the receiving platform is provided with a limiting part 14, which can limit the position of the upper end of the rear housing 2.

[0041] Furthermore, the keypad mounting position 11 and the main control board mounting position 12 are arranged sequentially from front to back in the front housing 1, and the RF circuit board mounting position 21 and the battery mounting position 22 are arranged sequentially from top to bottom in the rear housing 2.

[0042] Furthermore, the limiting part 14 includes two hooks extending downward from the lower surface of the accommodating platform, and the upper end of the rear housing 2 is provided with a top plate that matches the hooks.

[0043] In this embodiment, the front-to-back arrangement of the keypad mounting position 11 and the main control board mounting position 12, and the vertical arrangement of the RF circuit board mounting position 21 and the battery mounting position 22, enable the elongated keypad and main control board mounted inside the inner housing to have a compact and reasonable mounting structure, while the block-shaped RF circuit board and battery make reasonable use of the vertical space. The hook in the limiting part 14 can first limit the relative position of the upper end of the front housing 1 and the upper end of the rear housing 2 when the front housing 1 and the rear housing 2 are connected, ensuring that the fastening components 3 and the spare connecting components 4 on both sides of the front housing 1 and the rear housing 2 are aligned.

[0044] In one embodiment, the battery mounting position 22 is further provided with a battery clamping member 5, which can fix the battery in the battery mounting position 22. Furthermore, the battery clamping member 5 has snap-fit ​​parts on both sides that can be detachably snapped onto both sides of the rear housing 2, and a disc-shaped clamping part in the middle of the battery clamping member 5.

[0045] In this embodiment, after the battery is installed in the battery mounting position 22, the two sides of the battery clamping member 5 are respectively fastened to the two sides of the rear housing 2, thereby ensuring that the battery is clamped and preventing the battery from shifting. The detachable fastening structure facilitates subsequent battery replacement.

[0046] This utility model provides a beauty device, including a beauty device body, which includes the beauty device inner shell provided in any of the aforementioned embodiments, thereby making the internal component installation structure of the beauty device compact, making reasonable use of the internal space, and facilitating the miniaturization design of the beauty device.

[0047] As needed, the above technical solutions can be combined to achieve the best technical effect.

[0048] The above are merely the principles and preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several other modifications can be made based on the principles of this utility model, and these modifications should also be considered within the scope of protection of this utility model.
