[0017] Please refer to Figures 1 to 11. The radio frequency beauty device 100 of this embodiment is suitable for a user's skin. The radio frequency beauty device 100 uses radio frequency technology to generate heat in the skin tissue through the generated radio frequency current (or high frequency current), stimulating the proliferation and contraction of collagen. In addition, the radio frequency beauty device 100 of this embodiment can adjust the size of the main area of ​​action emitting radio frequency, and / or can provide a massage effect, which will be explained below.

[0018] As shown in Figure 2A, the radio frequency beauty instrument 100 of this embodiment includes a housing 105, a main circuit board 110, a drive unit 120, a gear set 130, and a radio frequency module 170. The main circuit board 110, the drive unit 120, and the gear set 130 are disposed within the housing 105.

[0019] The drive unit 120 is electrically connected to the main circuit board 110. The drive unit 120 is used to drive the gear set 130. The drive unit 120 is, for example, a motor, but the type of drive unit 120 is not limited thereto. In other embodiments, the drive unit 120 may also be a piezoelectric element or a shape memory alloy, etc.

[0020] As shown in Figures 2A and 5, the gear set 130 is coupled to the drive unit 120. These electrode units 140 are electrically connected to the main circuit board 110 and are linked to the gear set 130. These electrode units 140 are driven to rotate by the gear set 130.

[0021] Specifically, in this embodiment, the gear set 130 includes a first gear 132 and a plurality of second gears 134 meshing with the first gear 132. The first gear 132 is the driving gear, and the second gears 134 are the driven gears. The drive unit 120 drives the first gear 132, the first gear 132 drives the second gears 134, and the second gears 134 respectively drive the electrode units 140.

[0022] In this embodiment, the drive unit 120 is coaxial with the first gear 132, and each of the second gears 134 is coaxial with the corresponding electrode unit 140. These second gears 134 surround the first gear 132, and when the first gear 132 rotates, the direction of rotation of the first gear 132 is opposite to the direction of rotation of the second gears 134. Of course, the configuration of the drive unit 120, the first gear 132, and the second gears 134 is not limited to this.

[0023] Furthermore, in this embodiment, the number of second gears 134 and the number of electrode units 140 are three, but this is not a limitation. In other embodiments, there may be two or more.

[0024] The radio frequency (RF) module 170 includes an RF circuit 172 disposed on the main circuit board 110 and a plurality of electrode units 140 exposed outside the housing 105 and electrically connected to the RF circuit 172. These electrode units 140 are connected to the second gears 134 of the gear set 130 so as to be rotated by the second gears 134 of the gear set 130. The RF module 170 provides an RF current to the skin through the RF circuit 172 and these electrode units 140.

[0025] These electrode units 140 each include a plurality of electrode discs 142 and a plurality of electrode protrusions 144 located on these electrode discs 142. That is, each electrode unit 140 has one electrode protrusion 144 on its electrode disc. The protrusion height of the electrode protrusion 144 can be designed according to requirements. In one embodiment, the electrode unit 140 can contact the user's skin only through the electrode protrusion 144. In another embodiment, the electrode discs 142 can also contact the skin, and the electrode protrusion 144 can be the part that first contacts the user's skin and is the part that mainly outputs the frequency current.

[0026] As shown in Figures 1 and 5, in this embodiment, the two upper electrode disks 142 have the same diameter, while the lower one has a different diameter. Specifically, the diameter of the lower electrode disk 142 is larger than the diameter of the two upper electrode disks 142. For example, the diameter of the lower electrode disk 142 may be twice the diameter of the upper electrode disks 142, but this is not a limitation. In other embodiments, the electrode disks 142 may all have the same diameter or may all have different diameters.

[0027] As shown in Figures 2A and 6, in this embodiment, the radiofrequency beauty device 100 further includes a secondary circuit board 150 electrically connected to the main circuit board 110 and disposed between the gear set 130 and the electrode units 140. The electrode units 140 are connected to the secondary circuit board 150 and, through the secondary circuit board 150, to the main circuit board 110. In this embodiment, each of the electrode units 140 includes at least one spring pin connector 146 (Figure 6), through which each of the electrode units 140 is electrically connected to the secondary circuit board 150 by abutting against the at least one spring pin connector 146.

[0028] In addition, the sub-circuit board 150 includes a plurality of through holes 154 (FIG. 7), through which the electrode units 140 are respectively connected to the second gears 134 of the gear set 130.

[0029] As shown in Figure 7, in this embodiment, the sub-circuit board 150 includes a plurality of annular pads 152, each of which includes a plurality of annular lines 153. These annular lines 153 form the trajectory of each of the electrode units 140 during rotation. When the electrode units 140 are driven, the spring pin connector 146 of each of the electrode units 140 rotates along the corresponding annular line. In other embodiments, the annular pad 152 may also include only one annular line 153.

[0030] In this embodiment, there are, for example, three sets of annular pads 152, and each set of annular pads 152 has, for example, two annular lines 153. Each annular line 153 is the trajectory of the spring pin connector 146 corresponding to the electrode unit 140 when the annular pad 152 rotates. Therefore, by means of the design of the spring pin connector 146 and the annular pads 152 of the sub-circuit board 150, the electrode unit 140 can maintain the conductivity between the electrode unit 140 and the sub-circuit board 150 during rotation.

[0031] In this embodiment, the center of the electrode disk 142 is coaxial with the center of the second gear 134. Since the spring pin connector 146 is not located at the center of the electrode disk 142, in order to maintain the conductivity between the electrode unit 140 and the sub-circuit board 150 during rotation, the sub-circuit board 150 is correspondingly designed with an annular pad 152. In other embodiments, if the position of the second gear 134 is adjusted to make room for the center of the electrode disk 142, the spring pin connector 146 can also be located at the center of the electrode disk 142. In this case, the pad on the sub-circuit board 150 corresponding to the spring pin connector 146 can be a non-annular pad. In one embodiment, both the spring pin connector 146 and the second gear 134 can be located at the center of the electrode disk 142, without being limited by the drawings.

[0032] In addition, as shown in FIG3, the radio frequency beauty instrument 100 in this embodiment also includes a power button 162 and an adjustment button 160 exposed on the outer casing. The power button 162 and the adjustment button 160 are electrically connected to the main circuit board 110. The power button 162 is used to turn on the operation of the radio frequency beauty instrument 100, such as turning it on and off and switching the automatic rotation mode on and off. When the instrument is off, pressing and holding the power button 162 will turn it on; when the instrument is on, pressing and holding the power button 162 will turn it off. When the instrument is on, pressing the power button 162 twice will turn on the automatic rotation mode, and pressing the power button 162 once will turn off the automatic rotation mode. Of course, the function and operation of the power button 162 are not limited to this. The adjustment button 160 is used to control the rotation of the drive unit 120. The user can control the drive unit 120 by controlling the adjustment button 160, thereby adjusting the distance between the electrode protrusions 144.

[0033] As shown in Figures 8 to 11, when these electrode units 140 are driven to rotate by the gear set 130, the distance between these electrode protrusions 144 changes, so that these electrode protrusions 144 can adjust their relative positions according to the user's needs to change the range of radio frequency current.

[0034] Specifically, the area covered by these electrode protrusions 144 is the main area of ​​action of the radio frequency current emitted by these electrode units 140. In Figure 8, since the three electrode protrusions 144 of the three electrode units 140 are close to each other, the area Z1 covered by the three electrode protrusions 144 (the main area of ​​action of the radio frequency current emitted by these electrode units 140) is the smallest, which can be applied to small areas of skin such as around the eyes. Since the area of ​​the range Z1 is small, the generated heat energy can be more concentrated.

[0035] To adjust the range covered by the three electrode protrusions 144, simply move the adjustment knob 160. The drive unit 120 will cause the first gear 132 to rotate, and the second gears 134 will rotate accordingly, as shown in Figure 9. The three electrode units 140 will rotate accordingly, thereby changing the range covered by the three electrode protrusions 144.

[0036] As can be seen in Figure 10, since the three electrode protrusions 144 of the three electrode units 140 are far apart from each other, the area Z2 covered by the three electrode protrusions 144 (the main area of ​​action of the radio frequency current emitted by these electrode units 140) is the largest, which can be applied to areas such as the thighs or the abdomen, and the beauty procedure can be completed more quickly for these large areas of skin.

[0037] If the three electrode units 140 continue to rotate, the area covered by the three electrode protrusions 144 will decrease again, returning to the state shown in Figure 8. It is worth mentioning that in automatic rotation mode, in addition to the continuous change of the area affected by the radio frequency current, the rotation of the electrode protrusions 144 also has a massage function, providing a soothing and relaxing effect for the user.

[0038] Furthermore, in this embodiment, each electrode unit 140 can be either monopolar or multipolar radio frequency (RF), and the type of electrode unit 140 is not limited thereto. Monopolar RF has higher power, deeper penetration, and higher heating temperature, reaching directly to the dermis and even the SMAS fascia layer, stimulating fibroblasts to produce more collagen; resulting in plump and firm skin with noticeable and long-lasting effects. Multipolar RF has relatively lower and more stable energy, reaching the epidermis and superficial dermis, with a more even distribution of action, making it more suitable for minor fine lines, puffiness, and mild skin laxity. Both monopolar and multipolar RF electrode units 140 can be used in the design of the RF beauty instrument 100 of this embodiment.

[0039] In summary, the radio frequency module of the radio frequency beauty instrument of the present invention provides radio frequency current to the skin through radio frequency circuits and these electrode units, causing the skin tissue to generate heat. Furthermore, the main circuit board is electrically connected to the drive unit, which is coupled to a gear set. These electrode units are connected to the gear set and are driven to rotate by the gear set, thereby increasing ease of use to accommodate different usage scenarios.
