Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] like Figure 1 and Figure 2As shown, an embodiment of this utility model provides a beauty device with an improved base structure. To enhance sealing performance and waterproof / dustproof capabilities, the housing includes an outer shell 1 and an inner shell 2. The outer shell 1 is fitted over the inner shell 2, and the inner shell 2 is located inside the outer shell 1 and its position is fixed relative to the outer shell 2. The inner shell 2 further includes a front shell 21 and a rear shell 22. In the following description, for accuracy, the housing will be specifically described as outer shell 1, inner shell 2, front shell 12, and rear shell 22. The beauty device includes an outer shell 1, an inner shell 2 disposed within the outer shell 1, a main control circuit board 3 disposed within the inner shell 2, and a base 4 connected to the lower end of the inner shell 2.

[0032] The inner shell 2 is assembled from the front shell 21 and the rear shell 22. The base 4 includes an upper seat 41 that is snapped into the lower end of the inner shell 2 and a lower seat 42 that is fastened to the lower surface of the upper seat 41. The middle part of the base 4 is provided with a charging part 45 that passes through the upper seat 41 and the lower seat 42 and is electrically connected to the main control circuit board 3. The front side of the lower seat 42 is provided with an upwardly extending light-transmitting plate 43, and the rear side of the light-transmitting plate 43 is provided with an indicator light 44 that is electrically connected to the main control circuit board 3.

[0033] The beauty device employs a double-shell structure consisting of an outer shell 1 and an inner shell 2, enhancing its waterproof performance. The inner shell 2 also serves as a mounting bracket, allowing the internal components of the beauty device to be stably installed in a fixed position within it. The inner shell 2 is formed by the snap-fit ​​connection of the front shell 21 and the rear shell 22, facilitating the installation of internal components. The base 4 is formed by the snap-fit ​​connection of the upper base 41 and the lower base 42. The upper base 41 and the inner shell 2 form an internally sealed integral shell, significantly improving sealing performance. The lower base 42 is then fastened to the lower surface of the upper base 41 after the internal components and wiring have been installed, ensuring convenient installation and reliable connection.

[0034] The split base 4's structure allows for a more streamlined assembly process. The interlocking structure of the upper body 41 and lower body 42 simultaneously satisfies the requirements of stable connection and convenient assembly and disassembly. The charging unit 45 is located on the lower end of the beauty device rather than the side, which allows it to fit the charging base 4, simplifying the charging operation and improving the user experience. The light-transmitting plate 43 on the side of the base 4 conceals the indicator light 44, further improving the base 4's waterproof performance without affecting the indicator light 44's illumination effect, ensuring the beauty device's clean and aesthetically pleasing appearance.

[0035] In summary, the improved base structure of the beauty device provided by this utility model improves the structure of the shell and the base 4, allowing the split-structure base 4 to be securely connected to the lower end of the inner shell 2 in a way that facilitates installation and disassembly. This effectively speeds up the installation process of the base 4. Furthermore, by improving the internal structure and the structure of the main control circuit board 3, the charging part 45 is placed on the lower end face and a built-in indicator light 44 is provided, which significantly improves the sealing performance of the beauty device base 4. In addition, the position of the charging part 45 can be adapted to the charging base 4, significantly improving the sealing performance and charging convenience of the beauty device.

[0036] In one embodiment, such as Figure 2 As shown, the main control circuit board 3 is vertically disposed in the inner housing 2, and the lower end of the main control circuit board 3 is provided with a connection port 31 for connecting to the charging unit 45. Preferably, the charging unit 45 is covered with a sealing member 5. Further, the sealing member 5 includes a movable part 51 for covering the charging unit 45 and a connecting part 52 fixedly connected to the base 4. Further, the upper base 41 is provided with an upwardly protruding connecting post, the connecting part 52 of the sealing member 5 is embedded in the connecting post and its end passes through the upper end of the connecting post, and the movable part 51 is provided with a protruding structure that matches the shape of the charging unit 45, so that the movable part 51 can be partially inserted into the charging unit 45.

[0037] In this embodiment, the vertical layout of the main control circuit board 3 makes full use of the longitudinal space inside the inner shell 2, and the connection port 31 is directly aligned with the charging part 45, reducing the number of transition parts between the circuit board and the charging part 45, reducing the risk of poor contact, and facilitating quick insertion during assembly.

[0038] By providing a seal 5 at the lower charging section 45, the charging section 45 located on the lower end face can be prevented from being invaded by external liquids or dust. The seal 5 can be made of materials such as rubber or silicone. The movable part 51 is embedded and seals the charging section 45 by elastic deformation. The connecting part 52 can be integrally molded with the base 4 by injection molding process, ensuring that the seal 5 can still be tightly closed after long-term use, preventing liquids or dust from entering.

[0039] The seal 5 can also adopt a detachable connection structure with the base 4. The connecting column on the upper body 41 has a hollow structure inside. After the connecting part 52 of the seal 5 is embedded, it can be fixed by heat fusion to enhance the tensile strength of the seal 5. It can also be fixed by the end with a larger diameter and a limiting function. The protruding structure of the movable part 51 is interference-fitted with the inner wall of the charging part 45 to ensure the sealing of the charging part 45. At the same time, the opening and closing feel is clear and easy for the user to operate.

[0040] In one embodiment, such as Figure 3 and Figure 4As shown, the upper seat 41 is connected to the front housing 21 and the rear housing 22 respectively. Preferably, the upper surface of the upper seat 41 is provided with two protrusions 411, and the lower ends of the front housing 21 and the rear housing 22 are respectively provided with mounting notches that match the protrusions 411. The two protrusions 411 are respectively embedded in the mounting notches to achieve the snap-fit ​​between the upper seat 41 and the inner housing 2. Further, the upper surface of the lower seat 42 is provided with two upwardly protruding fasteners 421. The lower ends of the protrusions 411 are hollowed out to form a snap-fit ​​space that matches the fasteners 421. The fasteners 421 are embedded in the snap-fit ​​space and fastened.

[0041] In this embodiment, the protrusion 411 is a cuboid structure. The inner wall of the mounting notch can be provided with a guide slope structure. During assembly, the protrusion 411 slides into the notch along the slope and automatically locks itself without the need for additional tools. A limiting structure can also be provided to prevent the protrusion 411 from coming out in the opposite direction, ensuring that the upper seat 41 and the inner shell 2 are firmly connected.

[0042] The top of the fastener 421 is provided with a barb, and the inner wall of the snap-fit ​​space is provided with a groove or hook-shaped structure. After the barb engages with the groove or hook-shaped structure, a mechanical self-locking is formed, so that the base 4 is not easy to loosen even if it is pulled by external force. At the same time, the hollow design of the protrusion 411 can reduce the weight of the base 4.

[0043] In one embodiment, such as Figure 3 and Figure 4 As shown, the upper surface of the lower seat 42 is provided with two limiting posts 422, which are respectively embedded in both sides of the upper seat 41. Furthermore, the lower end faces of the front housing 21 and the rear housing 22 are respectively provided with threaded holes, and the upper seat 41 is provided with mounting through holes corresponding to the threaded holes. The upper seat 41 and the inner housing 2 are fixedly connected by screws.

[0044] In this embodiment, the diameter of the limiting post 422 is slightly larger than that of the limiting hole. The interference fit is used to achieve tight positioning, prevent the upper body 41 and the lower body 42 from shifting laterally, ensure that the fastener 421 is accurately aligned with the snap-fit ​​space, and improve the assembly success rate.

[0045] The screw connection serves as a redundant fixing method for the snap-fit ​​structure. The screw head is recessed into the surface of the upper body 41 to avoid protrusion affecting the appearance. A metal insert is pre-embedded in the threaded hole to enhance the thread strength and prevent stripping after repeated disassembly and assembly.

[0046] As needed, the above technical solutions can be combined to achieve the best technical effect.

[0047] 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.
