Description

Technical Field

[0001] This application relates to the field of medical aesthetic equipment technology, and in particular to a facial lifting beauty device. Background Technology

[0002] As people age, their facial muscles become loose and sag, making them look older. Those with sufficient financial means or who are concerned about their appearance may opt for cosmetic surgery. Current techniques involve surgically lifting the sagging facial muscles and then suturing them, or inserting multiple lifting threads into the face to lift the sagging muscles and make the face appear younger.

[0003] Surgery carries certain risks and can only maintain its effects for a limited time. Summary of the Invention

[0004] This application provides a facial lifting beauty device to improve the problem of sagging facial muscles.

[0005] This application provides a facial lifting beauty device, which includes: a head frame and lifting devices. The head frame is configured in an inverted U-shape, and the lifting devices are respectively disposed on both sides of the head frame.

[0006] The lifting device includes a lifting wheel, a micro motor, a limit switch, a central shaft, a spring, and a housing.

[0007] The lifting wheel is mounted on the central shaft and driven by a micro motor. When the lifting wheel rotates, it uses friction to generate an upward lifting force on the facial muscles. When the lifting force is greater than the set value, the lifting wheel stops rotating. When the lifting force is less than the set value, the lifting wheel starts rotating again, so that the lifting device always maintains an upward lifting force on the facial muscles.

[0008] In some examples, the set value is equal to the spring constant multiplied by the spring's travel distance.

[0009] In some examples, the travel distance of the spring is the distance the lifting device slides down from its starting position to the limit switch trigger point.

[0010] In some examples, the shape and material properties of the headgear allow the lifting device to exert elastic pressure on the face.

[0011] In some examples, a miniature motor drives the lifting wheel to rotate via gears.

[0012] In some examples, the lifting wheels in the lifting devices on both sides are mirror-symmetrically arranged and rotate synchronously but in opposite directions during operation, so as to balance the forces on both sides of the headgear.

[0013] In some examples, facial lifting beauty devices are equipped with an earphone function.

[0014] The facial lifting beauty device provided in this application has the following effects: the lifting devices are set on both sides of the headband. The lifting devices are mainly composed of lifting wheels, micro motors, limit switches, springs, central shafts, and housings. The lifting devices can move up and down relative to the headband within a set range in the vertical direction. A spring is provided between each lifting device and the headband. The elasticity of the springs makes the starting position of each lifting device at the upper end of its range of motion. The limit switches are normally closed, and their trigger positions are set at the lower end of the corresponding lifting device's range of motion to control the start and stop of the micro motors.

[0015] The central shaft is located in the housing. The lifting wheel in the lifting device is mounted on the central shaft and driven by a micro motor through gears. When the lifting wheel rotates, it uses friction to generate an upward lifting force on the facial muscles. When the lifting force is greater than the spring force installed between the headband and the lifting device, its reaction force causes the lifting device to move downward. When the lifting device moves to the limit switch trigger position, which is when the lifting force setting value is reached, the lifting wheel stops rotating. At this time, the spring force causes the lifting device to maintain an upward lifting force on the facial muscles. When the lifting force is less than the spring force, the spring force causes the lifting device to move upward away from the limit switch trigger position. The limit switch reconnects the circuit, and the lifting wheel rotates again to generate a lifting force, so that the lifting device always maintains an upward lifting force on the facial muscles. The magnitude of the lifting force is determined by the spring force. According to the spring force formula: Spring force = Spring force coefficient x Spring movement distance, the magnitude of the lifting force setting value = Spring force coefficient x Movement distance between the starting position of the lifting device and the limit switch trigger position.

[0020] Examples of embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application. Hereinafter, the facial lifting beauty device in the embodiments will be described in detail with reference to the accompanying drawings.

[0021] Please see Figure 1 as well as Figure 2 The facial lifting beauty device includes a headband 10 and lifting devices 20. The headband 10 is shaped like an inverted U, and the lifting devices 20 are respectively installed on both sides of the headband 10. Both lifting devices 20 can slide relative to the headband 10 within a set range. The shape, structure, and material properties of the headband 10 enable the lifting devices 20 on both sides to exert elastic pressure on the face.

[0022] The lifting device 20 mainly consists of a housing 12, a lifting wheel 13, a spring 14, a limit switch 15, a worm gear 16, a worm wheel 17, a central shaft 18, and a micro motor 19.

[0023] Specifically, the housing 12 of the lifting device 20 is provided with a sliding guide rail 11. The ends of both sides of the headgear 10 are fitted with the sliding guide rail 11 in the lifting device 20 and can move relative to each other in the sliding groove. That is, the headgear 10 and the lifting device 20 can slide relative to each other.

[0024] Figure 1 This is an overall schematic diagram of the facial lifting beauty device, showing the state of the facial lifting beauty device in use. Since the facial lifting beauty device is similar to the use of headphones, the inverted U-shaped headband 10 has its arc-shaped part worn on the top of the head and fixed relative to the head. Its two sides are roughly in a vertical state. Therefore, the lifting devices 20 on both sides can be understood as moving up and down within a range set in the vertical direction on both sides of the headband 10.

[0025] One end of the spring 14 is connected to the housing 12, and the other end is connected to the end of the headgear 10. The force of the spring 14 keeps the lifting device 20 in its initial position at the upper end of its vertical range of motion. For example... Figure 2 As shown, in this embodiment, the spring 14 is a compression spring. One end of the spring 14 abuts against the housing 12, and the other end abuts against the end of the headgear 10. The position where the housing 12 abuts against the spring 14 is located above the end of the headgear 10.

[0026] Further as Figure 2As shown, the spring 14 is installed as follows: the middle of the end of the headband 10 is hollowed out, and the spring 14 is inserted inside. The lower part of the spring 14 is fixed or placed in the frame formed after the headband 10 is hollowed out. The diameter of the spring 14 is larger than the thickness of the headband 10. That is, assuming the thickness of the headband 10 is 5mm, the diameter of the spring is 9mm. The spring 14 protrudes from both sides of the headband 10, so that each side of the spring 14 is 2mm larger than the surface of the headband 10. The part of the spring 14 protruding from the headband 10 can press against the housing 12 of the lifting device 20, so that when the lifting device 20 is subjected to the reaction force of the lifting wheel 13, it can compress the spring 14 and move downward. Figure 2 As shown, the limit switch 15 is fixed to the end of the headgear 10. The trigger position of the limit switch 15 is set at the lower end of the range of motion of the lifting device 20. The function of the limit switch 15 is to control the start and stop of the micro motor 19. In this embodiment, the limit switch 15 is normally closed, that is, when the lifting device 20 moves downward relative to the headgear 10 and touches the limit switch 15, the micro motor 19 stops working.

[0027] The central shaft 18 is mounted on the housing 12.

[0028] The lifting wheel 13 and the worm gear 17 are integrated as a single unit. The housing 12 has an opening, allowing the lifting wheel 13 to protrude from the housing 12 through the opening and thus come into contact with the facial skin. Both the lifting wheel 13 and the worm gear 17 are mounted on a central shaft 18, enabling the lifting wheel 13 to rotate around the central shaft 18.

[0029] A micro motor 19 is disposed inside the housing 12, and the micro motor 19 is connected to the lifting wheel 13 to drive the lifting wheel 13 to rotate. In this embodiment, as shown... Figure 2 As shown, the micro motor 19 drives the worm wheel 17 to rotate through the worm gear 16, so as to synchronously drive the lifting wheel 13 to rotate around the central axis 18.

[0030] When the lifting wheels 13 on both sides of the headband 10 rotate, they use the upper part of the headband 10 and the contact surface with the head as the fulcrum, and utilize friction to generate an upward lifting force on the facial muscles. The lifting wheels 13 in the two lifting devices 20 are mirror-symmetrically arranged and rotate synchronously in opposite directions, so that the lifting force on both sides of the face is equal, and the reaction force on both sides of the headband 10 is balanced. When the lifting wheel 13 rotates, the lifting force it generates on the face is greater than the force of the spring 14, and its reaction force causes the lifting device 20 to move downward. When the lifting device 20 moves to the trigger position of the limit switch 15, the limit switch 15 disconnects the circuit of the micro motor 19, and the lifting wheel 13 stops rotating. Because the transmission method used is a worm gear mechanism... The worm gear structure has a self-locking function. When the micro motor 19 stops rotating, the lifting wheel 13, which is linked to the worm gear 17, will not be reversed due to the reaction force. The lifting wheel 13 will remain in its original position and will not relax the lifting force. At the same time, the lifting force of the lifting device 20 on the facial muscles is maintained by the elasticity of the spring 14 and the facial muscles themselves. When the lifting force is less than the force of the spring 14 due to reasons such as muscle relaxation, the force of the spring 14 causes the lifting device 20 to leave the trigger position of the limit switch 15. The limit switch 15 reconnects the circuit of the micro motor 19, and the lifting wheel 13 rotates again to generate a lifting force on the facial muscles. This cycle continues, and the lifting device 20 always maintains an upward lifting force on the facial muscles during operation.

[0031] In this embodiment, the circuit of the two lifting devices 20 can be connected to the battery, switch and control circuit for the operation of the micro motor 19 through the headband 10 lead wire. It is the simplest switching circuit, which can be understood by general technicians, and a specific description is omitted here.

[0032] In practical applications, the length of the headband 10 on both sides is adjustable to accommodate different users. Since this is a conventional technology, it will not be described in detail in this embodiment.

[0033] Spring 14 in Figure 2 The structural diagram shows a compression spring structure, which is only a description of one embodiment and should not be construed as a limitation on the structure of spring 14. In practical applications, it can also be designed as a tension spring, torsion spring, etc. The same effect can be achieved by simply adjusting the installation position of spring 14.

[0034] Alternatively, in other embodiments, the limit switch 15 can also be installed on the housing 12, such as near the contact surface between the housing 12 and the spring 14. In this case, a protrusion needs to be provided at the end of the headgear 10 (on the movement path of the limit switch 15). When the housing 12 and the limit switch 15 move downward together and touch the protrusion of the headgear 10, the limit switch 15 is triggered to stop working.

[0035] Alternatively, in other embodiments, the limit switch 15 can also be replaced by a pressure sensor. When the lifting wheel 13 exerts a lifting force on the facial muscles, its reaction force is applied to the pressure sensor, and the pressure sensor controls the start and stop of the micro motor 19 through the control circuit.

[0036] Alternatively, in other embodiments, the micro motor 19 drives the lifting wheel 13 to rotate via gears. There are various ways to drive gears. In this embodiment, a worm gear 17 and worm 16 structure is used. Similarly, spur gears, planetary gears, and other transmission methods can also be used. If other transmission methods are used, a self-locking or anti-reverse mechanism needs to be added. These are conventional technologies and will not be described in detail here.

[0037] Optionally, in this embodiment, the housing 12 is provided with a sliding guide rail 11 to facilitate the interaction between the headgear 10 and the lifting device 20. The distance between their movements is to provide elastic buffer space for the spring 14. Figure 2 The structural diagram shown is only one of the possible solutions. Alternatively, the housing 12 and the headband 10 can be designed as a single unit, with the micro motor 19, worm gear 16, worm wheel 17, and lifting wheel 13 fixed on an independent bracket. This independent bracket is designed to slide up and down within a defined range on the face-facing side of the housing 12. The settings for the spring 14 and limit switch 15 can be referenced. Figure 2 This design approach can also achieve the same structural effect as [the previous one]. Figure 2 The structure provides the same functional effects. Optionally, since the facial lifting beauty device provided in this application has a shape and usage similar to a pair of headphones, it can be equipped with an auxiliary headphone function. That is, it can have a built-in headphone as an auxiliary function. The headphone can be wired, wireless, Bluetooth, etc., as needed, so that users can use the device for two purposes at once. While receiving beauty treatment, they can answer calls, listen to music, etc. Adding a headphone function is simply an extension of existing technology, which can generally be implemented by technicians and will not be described in detail here.

[0038] In summary, the facial lifting beauty device provided in this application is similar to the wearing method of headphones, is easy to use, and is suitable for long-term personal use at home during leisure time. It can improve the condition of sagging facial muscles and provide a non-surgical physical treatment solution for those who need beauty treatments for sagging facial muscles.

[0039] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the design intent and principles of this application should be included within the protection scope of this application.
