[0022] See Figures 1 to 6 This invention relates to a multifunctional skin rejuvenation device 100, which is a basic improvement over single roller-type beauty devices, EMS beauty devices, and LED beauty devices on the market. It adopts an integrated photoelectric design and has the characteristics of phototherapy, electrotherapy, and combined photoelectric treatment, providing more skin rejuvenation modes for users to choose from and improving the user experience.

[0023] In one embodiment, the multifunctional skin care device 100 includes a handle 10, a rotating shaft assembly 20, a massage roller 30, a circuit board 40, a power supply assembly 50, a button assembly 70, and a light source assembly 60.

[0024] The handle 10 includes an upper handle shell 12 and a lower handle shell 11, which are detachably connected and together define an inner cavity. Optionally, the handle 10 is curved, such as crescent-shaped, to facilitate user grip and improve the feel during use.

[0025] The rotating shaft assembly 20 is mounted on one end of the handle 10.

[0026] The massage roller 30 is made of a translucent material and is mounted on the rotating shaft assembly 20, allowing it to rotate relative to the assembly. During use, the roller can be rotated to press on the facial skin, providing physical therapy. It should be understood that the rotation of the massage roller 30 can be achieved through friction between the roller and the facial skin, or by using an electric component to drive the roller, such as a motor, to achieve electro-induced rotation.

[0027] The circuit board 40 is electrically connected to the power supply assembly 50 and is both located within the inner cavity. It is arranged sequentially with the massage roller 30 along the length of the handle 10, following the order of massage roller 30, circuit board 40, and power supply assembly 50. It is understood that the power supply assembly 50 may be a battery, preferably a rechargeable battery; or the power supply assembly may include a power interface for connecting to an external power source.

[0028] The button assembly 70 is located on the upper shell 12 of the handle and is electrically connected to the circuit board 40, so that the on / off state and working mode of the multifunctional skin beauty device 100 can be switched by pressing the button.

[0029] The light source assembly 60 includes a light source 61 electrically connected to the circuit board 40, which can be one of a halogen lamp, a tungsten filament lamp, a carbon filament lamp, an LED light panel, or an LD (Laser Diode) light panel. The light source 61 is mounted on the rotating shaft assembly 20 and covered by the massage rollers 30, and the light from the light source 61 can be emitted through the massage rollers 30. Preferably, to ensure the phototherapy effect, the wavelength of the light emitted by the light source 61 is 500~1800nm.

[0030] In one embodiment, the outer surface of the massage roller 30 is covered with a transparent conductive film 31, which is electrically connected to the circuit board 40. The transparent conductive film 31 is preferably an ITO conductive film, which generates a microcurrent when energized. This microcurrent stimulates the skin muscles, achieving anti-aging effects such as firming and lifting, reducing fine lines, and improving skin texture. In other words, this multifunctional skin care device 100 also functions as an EMS (Electrical Muscle Stimulation) beauty device.

[0031] In one embodiment, the transparent conductive film 31 is electrically connected to the circuit board 40 via a conductive component, which is located near the connection between the massage roller 30 and the shaft.

[0032] In one embodiment, the conductive component includes a conductive plate 81, on which a positive conductive ring and a negative conductive ring are provided, spaced apart. One of the positive and negative conductive rings 811 surrounds the other conductive ring 811. The transparent conductive film 31 is electrically connected to the two conductive rings 811, and the light source 61 passes through the middle portion of the conductive plate 81.

[0033] Optionally, the transparent conductive film 31 is electrically connected to two conductive rings 811 via a conductive sponge.

[0034] In one embodiment, the massage roller 30 has an inner ring with a mounting groove (not shown, the same below), and the edge of the conductive plate 81 is embedded in the mounting groove. By embedding the conductive plate 81 in the massage roller 30, the conductive plate 81 is avoided from occupying the length space of the rotating shaft, thereby reducing the size of the multifunctional skin beauty device 100.

[0035] In one embodiment, the conductive component further includes a conductive spring pin assembly, which comprises two conductive spring pins 82. One end of each conductive spring pin 82 is electrically connected to the circuit board 40, and the head end of each conductive spring pin 82 is correspondingly pressed against two conductive rings 811. Through the contact between the conductive spring pins 82 and the conductive rings 811, the heads of the conductive spring pins 82 can be pressed firmly against the conductive rings 811, improving the reliability of the electrical connection between them.

[0036] In one embodiment, the rotating shaft assembly 20 includes a rotating shaft housing and a light source bracket 23 mounted on the rotating shaft housing and protruding from the end of the rotating shaft housing. The light source bracket 23 includes a light source mounting cavity 231 and an electrode setting cavity 233, the electrode setting cavity 233 being disposed on one side of the light source mounting cavity 231 and integrally formed with the light source mounting cavity 231. The light source assembly 60 also includes a lampshade 62, the light source 61 being inserted into the light source mounting cavity 231, and the lampshade 62 covering the light source 61 with one end inserted into the light source mounting cavity 231. The conductive spring needle 82 is disposed in the electrode setting cavity 233 and its head can spring out from the electrode setting cavity 233. The massage roller 30 is sleeved on the outer periphery of the light source bracket 23.

[0037] The rotating shaft housing includes an upper rotating shaft housing 22 and a lower rotating shaft housing 21 that overlap each other. The light source bracket 23 is also provided with a mounting ring 232, and the light source bracket 23 is fixed to the rotating shaft housing by means of screws passing through the mounting ring 232 and the lower rotating shaft housing 21.

[0038] In this embodiment, the rotating shaft is used as a light source support 23 to mount the light source 61 and the conductive spring needle 82, thereby reusing the rotating shaft, improving its utilization rate, and making the skin beauty device more compact and smaller in size.

[0039] In one embodiment, the light source mounting cavity 231 of the light source bracket 23 includes a light source insertion cavity and a lampshade insertion cavity for setting the light source 61 and the lampshade 62, respectively. The lampshade insertion cavity and the light source insertion cavity are axially connected and communicate with each other. The outer diameter of the lampshade insertion cavity is larger than the outer diameter of the light source insertion cavity. The conductive plate 81 is sleeved on the outer periphery of the light source insertion cavity and abuts against the lampshade insertion cavity.

[0040] In one embodiment, the circuit board 40 is provided with a pair of positioning holes (not shown, the same below), which are arranged along the length of the circuit board 40. On the inner side of the handle 10, specifically on the lower shell 11 of the handle, a pair of positioning posts are provided at positions corresponding to the positioning holes. The positioning posts are inserted into the positioning holes, thereby completing the positioning assembly of the circuit board 40 and the handle 10.

[0041] The above embodiments show that the multifunctional skin care device 100 of the present invention has modes such as physical therapy, phototherapy, and electrotherapy. However, this should not be regarded as a limitation on the usage mode of the multifunctional skin care device 100 of the present invention. For example, the ITO conductive film can also be used in conjunction with an RF skin care device (i.e., a radio frequency face slimming device).

[0042] The massage roller 30 of the present invention has a surface morphology of rhombus, diamond pattern, or annular small facet, which can be set by technicians as needed.

[0043] The number of massage rollers 30 can be single, two, or more, and the number of light source assemblies 60 is the same as that of the massage rollers 30 and they are arranged in a one-to-one correspondence within the massage rollers 30. When two massage rollers 30 are provided, the rotating shaft assembly 20 is generally Y-shaped.
