Description

Technical Field

[0001] The present invention relates to the technical field of beauty devices, and particularly to beauty devices.

Background Art

[0002] With the improvement of consumers' living standards and the increasing awareness of beauty and skin care, the market for household beauty devices has been growing rapidly, and the needs of users for the diversity, portability, and ease of storage of devices have become increasingly prominent. Beauty devices in the current market are mainly classified into two types. One type is single-functional devices, which only have a single care function such as high frequency, introduction, or weak current. When users have multiple beauty needs, they need to purchase multiple types of devices, which not only increases the consumption cost, but also makes it inconvenient to carry and store due to the large number of devices, and it is difficult to cope with mobile scenarios such as business trips. Another type is composite-functional devices, which integrate multiple care modules. However, in many cases, an independent design and a distributed layout are adopted inside, and due to the low degree of integration of the structure, the overall volume of the device is large, the weight is heavy, the portability is poor, which not only reduces the willingness to use in mobile scenarios, but also brings obstacles to daily storage.

[0018] In the embodiments of the present invention, descriptions such as "first" and "second" are used only for describing purposes and should not be understood as indicating or implying relative importance or suggesting the number of technical features shown. Accordingly, features limited by "first" and "second" may explicitly or implicitly include at least one such feature.

[0019] Referring to FIGS. 1, 2, 3, and 10, the beauty device 1 according to the present embodiment includes a housing 10, an electrode head 20, a first main control board 31, a battery 32, a second main control board 33, and a fixing member 40. The housing 10 includes a first end 101 and a second end 102 that face each other along the longitudinal direction of the housing 10, and a storage chamber 103 is provided inside the housing 10. The electrode head 20 is provided inclined at the first end 101 of the housing 10. The contour of the electrode head 20 may be similar to, for example, a water droplet shape, an irregular ellipse, etc. The housing 10 may be made of a material such as PC (Polycarbonate), ABS (Acrylonitrile Butadiene Styrene), etc. The dimension of the housing 10 in the width direction gradually decreases from the center to both ends along the longitudinal direction of the housing 10, and the housing 10 has an arc-shaped region that smoothly transitions from the center to both ends. The first main control board 31 may integrate, for example, an adapter connection detection circuit module, an indicator lamp bead 316 control module, and a charging module. The functional modules on the second main control board 33 may be, for example, an MCU (Microcontroller Unit) main control chip module, a heating control circuit module, a lamp bead light drive circuit module, a waveform output circuit module, and a DCDC (Direct Current to Direct Current converter) lithium battery charging module. The battery 32 may be, for example, a rechargeable lithium battery.

[0020] The first main control board 31 is located within the housing chamber 103 and is provided close to the second end 102, and is fixedly connected to the housing 10. The first socket module 311 is provided on the side of the first main control board 31 facing the second end 102. The outer contour of the first main control board 31 is similar to an ellipse and is located at the bottom of the housing chamber 103 of the housing 12. The first main control board 31 is further provided with a charging interface 314, a button 315, and an indicator lamp bead 316, and is located on the side of the first main control board 31 facing the bottom of the housing 12. The bottom of the lower housing 12 has an area corresponding to the charging interface 314, the button 315, and the indicator lamp bead 316. The battery 32 is located within the housing chamber 103 and is provided adjacent to the side of the second main control board 33 away from the second socket module 331. The battery 32 is mounted perpendicular to the first main control board 31, the height of the battery 32 extends along the longitudinal direction of the housing 10, the length of the battery 32 is the maximum length of the first main control board 31, the thickness of the battery 32 is located in the width direction of the first main control board 31, and the distance between the opposing sides of the battery 32 and the first main control board 31 in the width direction is equal.

[0021] The second main control board 33 is located within the housing chamber 103 and is mounted perpendicular to the surface of the first main control board 31 that is away from the first socket module 311. The second main control board 33 has a second socket module 331 located close to the first main control board 31, and the second main control board 33 achieves an electrical connection with the first main control board 31 by connecting the second socket module 331 and the first socket module 311 via a conductor. The second main control board 33 further includes a third socket module 332 located at the end of the second main control board 33 closest to the electrode head 20, and the electrode head 20 is provided with a fourth socket module 221, and the second main control board 33 and the electrode head 20 are connected to the third socket module 332 and the fourth socket module 221 via a conductor, thereby achieving a connection between the second main control board 33 and the electrode head 20.

[0022] The fixing member 40 is fixedly connected to the housing 10, the fixing member 40 is located within the housing chamber 103, the second main control board 33 is inserted into the fixing member 40 and connected to the fixing member 40 with its position restricted, and the battery 32 is connected to the fixing member 40 with its position restricted. The second main control board 33 and the battery 32 are fixedly connected to the housing 10 via the fixing member 40. The fixing member 40 is located within the housing chamber 103 and is fixedly connected to the upper housing 11 and the lower housing 12, and the sides of the second main control board 33 and the battery 32 away from the first main control board 31 are both connected to the fixing member 40 with their position restricted.

[0023] The fixing member 40 simultaneously provides the functions of insertion and positioning for the second main control board 33, position restriction and restraint for the end of the battery 32, and synchronously fixing the second main control board 33 and the battery 32 to the housing 10. This not only simplifies the assembly process but also reduces the space occupied by structures required to individually fix multiple components. Furthermore, the fixing member 40 forms a stable, integrated assembly structure for each component, effectively preventing loosening or displacement of components due to factors such as vibration during product use and ensuring the operational stability of the equipment.

[0024] The first main control board 31 is provided close to the second end 102 of the housing 10, and both the battery 32 and the second main control board 33 are provided perpendicular to the surface of the first main control board 31 away from the first socket module 311. This layout overcomes the space limitations of conventional tile-type assembly, and by arranging core components such as the main control board and battery 32 three-dimensionally and in layers along the longitudinal direction of the housing 10, each component forms a compact assembly unit within the housing chamber 103, thereby avoiding space redundancy caused by horizontally dispersing the components. By integrating multiple functional modules with functions such as high frequency and weak current on the first and second main control boards, the space occupied by functional components is reduced by replacing the conventional dispersed layout of independent functional modules. Furthermore, by providing the second socket module and the first socket module adjacent to each other, the spacing between components is further optimized, the electrical connection path is shortened, space redundancy caused by the dispersed arrangement of socket modules is avoided, and the space utilization rate inside the housing is effectively improved.

[0025] Referring to Figures 6, 7, 8, and 9, in some embodiments, the widthwise dimension of the fixing member 40 gradually decreases from the center to both ends along the longitudinal direction of the fixing member 40. The fixing member 40 includes opposing third and fourth ends 401 and 402 along the longitudinal direction of the fixing member 40. The outer contour of the fixing member 40 is similar to an ellipse, and the entire fixing member 40 has a shape that is wider in the middle and narrower at both ends. This not only allows for stable support of the ends of the battery 32 and the inserted second main control board 33 through the wider area in the middle, but the design with narrow ends also allows for adaptation to the gradient change of the internal space along the longitudinal direction of the housing 10, avoiding the creation of a gap between the fixing member 40 and the inner wall of the housing 10, which would further compress the internal space.

[0026] Referring to Figures 7, 8, and 9, the fixing member 40 has an opening 403 that is located in the longitudinal direction of the fixing member 40, the length of the battery 32 is located in the longitudinal direction of the first main control board 31, the thickness of the battery 32 is located in the width direction of the first main control board 31, and is provided in correspondence with the length and thickness of the battery 32, is located in the longitudinal direction of the fixing member 40, and extends toward the third end 401 and the fourth end 402, with the extending direction coinciding with the direction connecting the third end 401 and the fourth end 402, and the fixing The battery 32 is provided with two first side walls 404 located on the side of the fixing member 40 closest to the first end 101 and on opposite sides of the opening 403 (for example, on opposite sides of the opening 403 in the width direction of the fixing member 40) and a second side wall 405 connected to one end of the two first side walls 404 away from the fixing member 40, and together with the two first side walls 404, passing through the opening 403 of the battery 32 and surrounding the side closest to the first end 101. The two first side walls 404 and the second side wall 405 surround each other to form a housing groove 412, and the opening of the housing groove 412 communicates with the opening 403. The side of the battery 32 closest to the first end 101 is located within the housing groove 412, enabling a positional connection with the fixing member 40. This eliminates the need for an independent support structure, significantly reducing the number of components and space occupied. As a result, the core member is compactly co-supported on the fixing member 40, improving internal density.

[0027] The fixing member 40 includes a first surface 413 facing the first end 101 and a second surface 414 facing the second end 102, the opening 403 penetrates the first surface 413 and the second surface 414, and the outer contour of the opening 403 is rectangular. The two first side walls 404 are both located on the first surface 413 and connect the two opposing sides of the opening 403 in the width direction of the fixing member 40, and extend away from the fixing member 40. The second side wall 405 and the two first side walls 404 surround each other to form a housing groove 412, the opening of the housing groove 412 faces the opening 403, and the housing groove 412 communicates with the opening 403, and one end of the battery 32 away from the first main control board 31 is located in the housing groove 412 to avoid relative displacement of the battery 32.

[0028] Referring to Figures 5 and 9, in some embodiments, the fixing member 40 is provided with two third side walls 406 located on the side of the fixing member 40 toward the second end 102. The two third side walls 406 each extend toward the second end 102 from the two first side walls 404. The two third side walls 406 are located on the second surface 414 of the fixing member 40 and are connected to the connection point between the first side walls 404 and the fixing member 40. The third side walls 406 extend toward the fixing member 40 and together with the fixing member 40 and the first side walls 404 form an integrated support and position limiting structure, eliminating the need to assemble separate reinforcing or positioning members and reducing the number of internal parts and space occupied. The direction in which the third side wall 406 extends toward the second end 102 of the housing 10 coincides with the arrangement direction of the internal components, allowing the housing 10 to adapt to a space-reducing configuration along the longitudinal direction of the housing 10, further compressing the internal space and contributing to a reduction in the overall volume of the equipment.

[0029] Here, the two third side walls 406 and the two first side walls 404 are all located on opposite sides of the opening 403 in the width direction of the fixing member 40. The third side walls 406 form a cooperative layout with the first side walls 404 and act together with the groove wall structure of the housing groove 412 to expand the coverage area of ​​the groove wall of the housing groove 412. Because the contact area between the groove wall of the housing groove 412 and the battery 32 is larger, the clamping and supporting forces applied to the end of the battery 32 can be distributed, thereby avoiding displacement of the battery 32 due to local pressure concentration, improving the fit and tightness between the battery 32 and the housing groove 412, effectively preventing the battery 32 from moving during product movement or vibration, and ensuring the stability of the battery 32 assembly.

[0030] Referring to Figures 6, 7, 8, and 9, in some embodiments, the fixing member 40 is provided with a first through hole 407 in which the second main control board 33 is inserted, and a second through hole 408 which communicates with the first through hole 407, and the distance between the opposing ends of the first through hole 407 in the longitudinal direction of the fixing member 40 is greater than the distance between the opposing ends of the second through hole 408 in the longitudinal direction of the fixing member 40, and the second main control board 33 is provided with a functional module located within the second through hole 408. The first through hole 407, the second through hole 408, and the opening 403 are provided adjacent to each other in the width direction of the fixing member 40.

[0031] The second through-hole 408 provides through-type assembly passages to multiple functional modules of the second main control board 33, and the first through-hole 407 provides an insertion passage and clamping / position restriction to the second main control board 33, thereby preventing the second main control board 33 from shifting position in the width direction of the fixing member 40. The first through-hole 407 forms engagement constraints with respect to both edges of the second main control board 33 from the longitudinal direction of the fixing member 40, and this double position restriction structure effectively prevents the second main control board 33 from shaking or displacing during equipment use or vibration, ensuring the stability of the electrical connection between the second main control board 33 and the first main control board 31 and battery 32.

[0032] Referring to Figures 6, 7, 8, and 9, in some embodiments, the first through hole 407 and the first side wall 404 are spaced apart. This avoids compressive deformation of the battery 32 due to forced contact with the main control board and prevents the risk of leakage and short circuits caused by damage to the housing of the battery 32. The fixing member 40 is provided with a first extending wall 409 located on a surface of the fixing member 40 away from the first side wall 404 and extending in a direction toward the second end 102, with one end of the fixing member 40 connected to the side of the opening 403 closer to the second main control board 33 and the other opposite end connected to the side of the first through hole 407 away from the first side wall 404, and a second extending wall 410 connected to one end of the first extending wall 409 away from the opening 403 and perpendicular to the first extending wall 409.

[0033] Referring to Figure 9, both the first extending wall 409 and the second extending wall 410 are located on the second surface 414 of the fixing member 40 and both extend in a direction away from the fixing member 40. The side of the first extending wall 409 away from the second surface 414 abuts against the second main control board 33. The first extending wall 409 is connected between the opening 403 and the first through hole 407, forming a rigid connecting bridge between the opening 403 and the first through hole 407, and the second extending wall 410 and the first extending wall 409 form an L-shaped extending support structure. The first extending wall 409 and the second extending wall 410 effectively increase the contact wall area of ​​the first through hole 407, thereby improving the contact area with the second main control board 33. This larger contact area distributes the clamping stress exerted by the first through hole 407 on the second main control board 33, preventing deformation or surface damage to the second main control board 33 due to excessive local pressure. Furthermore, the large-area close contact improves the frictional force between the first through hole 407 and the second main control board 33, effectively preventing the second main control board 33 from loosening or moving during equipment vibration or movement, thus ensuring the assembly accuracy and positional stability of the second main control board 33.

[0034] Referring to Figures 4, 5, and 12, in some embodiments, the widthwise dimension of the first main control board 31 gradually decreases from the center to both ends along the longitudinal direction of the first main control board 31. The first main control board 31 conforms to the space contraction configuration along the longitudinal direction inside the housing 10 and adheres tightly to the inner wall of the housing 10 without gaps, thereby avoiding the space waste of conventional equal-width main control boards caused by redundant dimensions at both ends. The length of the battery 32 is equal to the maximum length of the first main control board 31. This avoids problems of lifting or overlapping interference at the ends due to the battery 32 not matching the length of the main control board, eliminates the need to provide a separate longitudinal position limiting buffer structure, further compresses the space occupied by the entire core member, and enables high-density integration of important components within the housing chamber 103.

[0035] Here, the first main control board 31 is provided with a plurality of first screw holes 312, and the internal housing chamber 103 of the lower housing 12 is provided with a plurality of first studs 122. The first main control board 31 is fixedly connected to the lower housing 12 by bolts passing through the first screw holes 312 and being fixed into the first studs 122, effectively preventing the first main control board 31 from shifting position or becoming loose during use.

[0036] A hypotenuse 333 is provided at one end of the second main control board 33 that is away from the first main control board 31, and this hypotenuse 333 is provided adjacent to the electrode head 20. The angle of the hypotenuse 333 is compatible with the inclined structure of the electrode head 20, allowing for full utilization of the inclined, unused space below the electrode head 20, and enabling efficient use of the narrow area at the first end 101 of the housing 10. Combined with the compact arrangement of the aforementioned components, this increases the overall internal integration of the device.

[0037] Referring to Figures 10, 11, and 12, in some embodiments, the housing 10 includes an upper housing 11 and a lower housing 12, the electrode head 20 is provided in the upper housing 11, and the first main control board 31 is provided in the lower housing 12. The upper housing 11 and the lower housing 12 are connected by the fixing member 40, and a plurality of protrusions 121 are provided on the side of the lower housing 12 closer to the upper housing 11. The fixing member 40 is provided with a plurality of grooves 411 corresponding to the plurality of protrusions 121, and the fixing member 40 is fixedly connected to the lower housing 12 by the mutual fitting of the protrusions 121 and the grooves 411. An annular stopper 415 is provided on the second surface 414 of the fixing member 40, the annular stopper 415 is provided close to the edge contour of the fixing member 40, and the annular stopper 415 extends toward the second end 102 of the housing 10. When multiple grooves 411 are provided in the annular stopper 415 and the fixing member 40 is connected to the lower housing 12, the annular stopper 415 is located inside the lower housing 12, and multiple corresponding protrusions 121 are provided on the inner wall of the lower housing 12, and the fixing member 40 and the lower housing 12 are fixedly connected by the engagement of the protrusions 121 and the grooves 411. There is no need to separately provide a connecting bracket or fastener for the independent housing 10, and the space occupied by the number and structure of parts is reduced.

[0038] Referring to Figures 7 and 11, in some embodiments, a first annular groove 111 is provided at the end of the upper housing 11 closest to the lower housing 12, and the edge of the fixing member 40 is located within the first annular groove 111. The edge of the fixing member 40 is fitted into the first annular groove 111 to form a nested fitting structure between the upper housing 11 and the fixing member 40. The fitting structure utilizes the annular groove space at the end of the upper housing 11 to support the edge of the fixing member 40, eliminating the need to separately secure a connecting gap between the fixing member 40 and the upper housing 11, and ensuring that the three components—the upper housing 11, the fixing member 40, and the lower housing 12—do not occupy redundant space in the radial direction. Furthermore, by combining the annular groove enclosing the edge of the fixing member 40 to restrict its position with the axial fixing between the projection 121 of the lower housing 12 and the groove 411, dual radial and axial positioning of the fixing member 40 within the housing 10 is achieved, eliminating the need to add a separate positioning bracket, further compressing the space of the internal structure, and enhancing the miniaturization design of the entire device.

[0039] Referring to Figures 7, 8, and 11, in some embodiments, multiple contact portions 112 are provided at intervals within the upper housing 11, and when the fixing member 40 is fixedly connected to the upper housing 11, the multiple contact portions 112 come into contact with the fixing member 40. Each contact portion 112 works in close contact with the surface of the fixing member 40, and the multi-point contact structure allows for the application of uniform preload from different directions of the fixing member 40. Next, the contact portions 112 evenly distribute the impact force applied from the outside to multiple force-receiving points of the fixing member 40, thereby avoiding deformation of the fixing member 40 due to stress concentration or loosening of the connection of the housing 10.

[0040] Here, the first surface 413 of the fixing member 40 is provided with a plurality of second screw holes 416, and the interior of the upper housing 11 is provided with a plurality of second studs 114 corresponding to the plurality of second screw holes 416. By having bolts pass through the second screw holes 416 and be fixed into the second studs 114, a fixed connection is achieved between the fixing member 40 and the upper housing 11, effectively preventing the effects of external forces such as vibration and dropping during the use of the equipment and preventing displacement of the fixing member 40. By combining the nested fitting of the annular groove and the tight contact of the contact portion 112, the redundant assembly gap between the fixing member 40 and the upper housing 11 can be reduced, eliminating the need to separately add a positioning and cushioning structure and further compressing the internal space occupied.

[0041] Referring to Figures 2, 4, and 10, in some embodiments, the electrode head 20 includes a mounting plate 21, an electrode plate 22, an electrode point 23, and a contact portion 24. The electrode plate 22 is located on the mounting plate 21. The electrode point 23 is provided on the side of the electrode plate 22 away from the mounting plate 21, and the electrode point 23 is electrically connected to the electrode plate 22. The contact portion 24 is provided with a plurality of through holes 241, the contact portion 24 is provided on the electrode plate 22, and the electrode point 23 is located within the through holes 241. The electrode point 23 is fixedly connected to the electrode plate 22, and the contact portion 24 is provided with a plurality of third studs 243, and the mounting plate 21 is provided with a plurality of corresponding third screw holes 211, and bolts are fixed through the third screw holes 211 into the third studs 243, thereby achieving a fixed connection between the mounting plate 21 and the contact portion 24, and the electrode plate 22 is sandwiched and fixed between the mounting plate 21 and the contact portion 24.

[0042] An annular extension 242 is provided on the side of the contact portion 24 facing the electrode plate 22, and a second annular groove 113 corresponding to the annular extension 242 is provided in the upper housing 11, and the contact portion 24 is connected to the upper housing 11 via the annular extension 242 and the second annular groove 113. The annular extension 242 is fitted into the second annular groove 113, eliminating the need to add fastening members such as bolts or clips, reducing the space occupied by the connection structure, ensuring there are no redundant gaps in the connection area between the electrode head 20 and the upper housing 11, and improving the space utilization rate at the end of the housing 10. Furthermore, the annular, tightly fitting connection method enhances the sealing performance of the connection between the electrode head 20 and the upper housing 11, further improving the protective performance against internal components.

[0043] In this embodiment, the device body includes two buttons, one of which is a power mode button and the other is a level button. The device body includes three indicator lamp beads, each of which can be programmed to illuminate blue, red, and orange light. When the indicator lamp beads are controlled to illuminate blue and red light simultaneously, purple light is displayed. The device body includes a charging interface and can be charged using a 5V Type-C interface. When using the beauty device, the user can achieve skincare simply by adjusting the mode and level according to the function description and bringing the electrode head into contact with the skin (i.e., the electrode part touching the skin). The function description of the beauty device according to this embodiment is as follows.

[0044] Pressing and holding the power button for 1.5 seconds powers on the device, and after startup, it defaults to Mode 1, Level 1. Pressing and holding the power button for 1.5 seconds again turns off the device and stops it from operating. Mode 1 combines a weak current with simultaneous illumination of 460nm blue light and 630nm red light, Mode 2 combines a 2MHz high frequency with 630nm red light, and Mode 3 combines a weak current, a 2MHz high frequency with 590nm orange light. Each mode lasts for 5 minutes, and a short press of the power button cycles through Mode 1 → Mode 2 → Mode 3 → Mode 1, correspondingly displaying purple light → red light → orange light → purple light on the electrode head. A short press of the level button cycles through Level 1 → Level 2 → Level 3 → Level 1, and when the power is turned on, it defaults to Level 1.

[0045] When adjusting the level in Mode 1, Level 1 corresponds to one indicator lamp bead being constantly lit purple, Level 2 corresponds to two indicator lamp beads being constantly lit purple, and Level 3 corresponds to three indicator lamp beads being constantly lit purple. When adjusting the level in Mode 1, the output voltage parameter is adjusted and increases sequentially as the level is increased.

[0046] When adjusting the level in Mode 2, Level 1 corresponds to one indicator lamp bead being constantly lit red, Level 2 corresponds to two indicator lamp beads being constantly lit red, and Level 3 corresponds to three indicator lamp beads being constantly lit red. When adjusting the level in Mode 2, the output voltage parameter is adjusted, and the parameter also increases sequentially as the level increases.

[0047] When adjusting the level in Mode 3, Level 1 corresponds to two indicator lamp beads being constantly lit orange, Level 2 corresponds to two indicator lamp beads being constantly lit orange, and Level 3 corresponds to three indicator lamp beads being constantly lit orange. When adjusting the level in Mode 3, the output voltage parameters of Mode 1 and Mode 2 are adjusted simultaneously, and the parameters also increase sequentially as the level is increased.

[0048] During charging, the three indicator light beads flash sequentially in purple like flowing water, and when charging is complete, all three indicator light beads light up purple. Note that the device cannot be powered on while charging. Each time the device is powered on, it operates continuously for 5 minutes, then automatically powers off. If the mode is switched during this time, the countdown restarts from the beginning. The device will also automatically power off if no button operations are performed for 5 minutes after powering on. When the battery level is low, the indicator light beads continue to flash, maintaining the color and number of lights corresponding to the current mode and level. If the battery level is too low, the indicator light beads will flash, the buzzer will beep 5 times, and then the device will automatically power off. In mode 2, the device will emit two beeps every minute to prompt the user to change the treatment area for the facial lift. In any mode, when the electrode head comes into contact with the skin, the lamp beads switch to a high-brightness state, and when the beauty head leaves the skin, the brightness of the lamp beads automatically decreases.
