Detailed Implementation

[0029] The following is for reference. Figures 1-8 A beauty device 100 according to an embodiment of the present utility model is described.

[0030] like Figures 1-8 As shown, the beauty device 100 according to an embodiment of the present invention includes: a main body 10, a first care head 20, and a second care head 30.

[0031] Specifically, the main bodies 10 have a first direction that is orthogonal to each other (e.g., Figure 1 (the vertical direction in the middle), the second direction (for example, Figure 1 (in the left and right directions) and third direction (e.g., Figure 1 (In the front-back direction). The first nursing head 20 is located on one side of the main body 10 in the first direction. The first nursing head 20 includes a first housing 201 and a plurality of first electrodes 202. In the description of this utility model, "a plurality of" means two or more. The plurality of first electrodes 202 are all disposed on the first housing 201 and spaced apart along the second direction. The second nursing head 30 is located on the other side of the main body 10 in the first direction. The second nursing head 30 includes a second housing 301 and a plurality of second electrodes 302. The plurality of second electrodes 302 are all disposed on the second housing 301 and spaced apart along the second direction.

[0032] The instruction manual requires that the first direction can be the height direction of the main body 10, the second direction can be the length direction of the main body 10, and the third direction can be the thickness direction of the main body 10.

[0033] For example, in Figures 1-8In the example, the main body 10 has a receiving cavity, within which a circuit board and a power supply component are disposed. A first care head 20 is mounted on one side of the main body 10 in the height direction. The first housing 201 of the first care head 20 may include an inner housing 2013 and an outer housing 2014. A plurality of first electrodes 202 are disposed on the outer housing 2014 and electrically connected to the circuit board. The plurality of first electrodes 202 are evenly spaced along the length direction of the main body 10. The surface of each first electrode 202 away from the main body 10 is flush with the outer surface of the outer housing 2014 to ensure the flatness of the outer surface of the first care head 20. A second care head 30 is mounted on the other side of the main body 10 in the height direction. The first housing 201 of the second care head 30 may also include an inner housing 2013 and an outer housing 2014. A plurality of second electrodes 302 are also evenly spaced along the length direction of the main body 10. The surface of each second electrode 302 away from the main body 10 is flush with the outer surface of the second housing 301 to ensure the flatness of the outer surface of the second care head 30.

[0034] Specifically, the number of first electrodes 202 on the first housing 201 can be greater than or equal to six. For example, the number of first electrodes 202 can be six (e.g., Figure 1 As shown), eight (as shown) Figure 5 As shown), nine (as shown) Figure 6 As shown), eleven (as shown) Figure 7 (As shown). The number of second electrodes 302 on the second housing 301 can be greater than or equal to six; for example, the number of second electrodes 302 can be seven (e.g.). Figure 3 As shown), eleven (as shown) Figure 8 (As shown).

[0035] The shapes of the first housing 201 and the second housing 301 may differ; and / or the shapes of the first electrode 202 and the second electrode 302 may also differ. Users can choose either the first treatment head 20 or the second treatment head 30 for skincare according to their own needs, making the beauty device 100 suitable for different users, thus improving its practicality and applicability, and ultimately enhancing the user experience.

[0036] Of course, the shape of the first housing 201 and the shape of the second housing 301 can be the same; and / or the shape of the first electrode 202 and the shape of the second electrode 302 can also be the same. When one of the first treatment head 20 and the second treatment head 30 is damaged, the user can continue to use the other one, reducing the maintenance cost of the beauty device 100.

[0037] According to an embodiment of the present invention, the beauty device 100 has a first treatment head 20 and a second treatment head 30 respectively disposed on both sides of the height direction of the main body 10. The first treatment head 20 includes a plurality of first electrodes 202, and the second treatment head 30 includes a plurality of second electrodes 302. Therefore, compared with traditional handheld beauty devices, on the one hand, the beauty device 100 can be used by different users, improving its practicality and applicability, thereby enhancing the user experience; on the other hand, the first treatment head 20 and the second treatment head 30 can be used alternately, extending the service life of the beauty device 100 while reducing its maintenance costs.

[0038] According to some embodiments of this utility model, such as Figure 1 and Figures 5-8 As shown, in the projection plane of the third direction, the length of the first housing 201 gradually increases in the second direction towards the main body 10. That is, in the front projection of the beauty device 100, the length of the end of the first housing 201 furthest from the main body 10 is longer, and the length of the end of the first housing 201 adjacent to the main body 10 is shorter, making the front shape of the first housing 201 roughly trapezoidal. Therefore, when a user uses the beauty device 100 for large-area skincare, the end of the first housing 201 furthest from the main body 10 can come into contact with the user's skin, increasing the contact area between the first housing 201 and the skin. This, in turn, increases the contact area between the first electrode 202 and the skin, resulting in a better skincare effect and facilitating the miniaturization of the beauty device 100.

[0039] And / or, such as Figure 1 and Figures 5-8 As shown, in the projection plane of the third direction, the length of the second housing 301 gradually increases in the second direction towards the main body 10. That is, in the front projection of the beauty device 100, the length of the end of the second housing 301 away from the main body 10 is smaller, and the length of the end of the second housing 301 adjacent to the main body 10 is longer, making the front shape of the second housing 301 roughly an inverted trapezoid. Therefore, when the user uses the beauty device 100 for small-area skin care (such as the sides of the nose or the jawline), the end of the second housing 301 away from the main body 10 can contact the user's skin, allowing the second electrode 302 to contact the narrow area of ​​the face, so that the beauty device 100 has a good skin care effect, further improving the practicality and applicability of the beauty device 100, and also facilitating the miniaturization design of the beauty device 100.

[0040] Furthermore, a portion of the second housing 301 is recessed in the direction toward the main body 10 to form a recessed portion 3011, and the recessed portion 3011 is located in the middle of the second housing 301. (Refer to...) Figure 1 and Figures 5-8The surface of the second housing 301, on the side away from the main body 10, is recessed towards the main body 10 to form a recessed portion 3011, so that the front shape of the second housing 301 is roughly W-shaped. This design makes the shape of the second housing 301 more ergonomic. When the user uses the first care head 20 for skin care, the web of the user's hand can fit into the recessed portion 3011, making it easier for the user to hold the beauty device 100 firmly and ensuring comfort during use. When the user needs to care for the jawline, the second care head 30 can be used, allowing the recessed portion 3011 to fit snugly against the jawline for better facial skin care.

[0041] According to some embodiments of this utility model, such as Figure 2 As shown, within the projection plane in the third direction, the cross-sectional shapes of both the first housing 201 and the second housing 301 are arc-shaped. In other words, the outer surfaces of the first housing 201 and the second housing 301 are arc-shaped surfaces, and both the first housing 201 and the second housing 301 protrude in a direction away from the main body 10. Therefore, when performing skincare, the user can easily make the electrodes fit against the skin by slightly rotating the beauty device 100, ensuring both the contact area between the electrodes and the skin and further guaranteeing user comfort.

[0042] In the third direction, each first electrode 202 extends circumferentially along the first housing 201, and at least one surface of each first electrode 202 in the second direction is an arcuate surface. (Refer to...) Figures 4-8 Each first electrode 202 has arc-shaped surfaces on both sides in the second direction to ensure that the gap between adjacent first electrodes 202 at each position is consistent, thus ensuring the regularity of the arrangement of multiple first electrodes 202 on the first housing 201 and improving the aesthetics of the first nursing head 20.

[0043] And / or, in a third direction, each second electrode 302 extends circumferentially along the second housing 301, and at least one surface of each second electrode 302 in the second direction is an arcuate surface. (Refer to...) Figure 3 and Figure 8 Each second electrode 302 has arc-shaped surfaces on both sides in the second direction to ensure that the gap between adjacent second electrodes 302 at each position is consistent, thus ensuring the regularity of the arrangement of multiple second electrodes 302 on the second housing 301 and improving the aesthetics of the second nursing head 30.

[0044] Furthermore, the plurality of first electrodes 202 are symmetrical about the center of the first housing 201 in the second direction, further ensuring the regularity of the arrangement of the plurality of first electrodes 202 on the first housing 201 and further improving the aesthetics of the first nursing head 20. The length of the plurality of first electrodes 202 gradually decreases along the direction away from the center of the first housing 201. (Refer to...) Figures 4-8Along the length of the main body 10, the first electrode 202 closer to the center of the first housing 201 is longer, while the first electrode 202 closer to the edge of the first housing 201 is shorter. Since the first electrode 202 closer to the center of the first housing 201 is in contact with the skin for a longer period during use, by designing the first electrode 202 closer to the center of the first housing 201 to be longer and the first electrode 202 closer to the edge of the first housing 201 to be shorter, the contact area between the multiple first electrodes 202 and the skin can be guaranteed while reducing the cost of the beauty device 100.

[0045] And / or, the plurality of second electrodes 302 are symmetrical about the center of the second housing 301 in the second direction, further ensuring the regularity of the arrangement of the plurality of second electrodes 302 on the second housing 301 and further improving the aesthetics of the second nursing head 30. The length of the plurality of second electrodes 302 gradually decreases along the direction away from the center of the second housing 301. (Refer to...) Figure 3 and Figure 8 Along the length of the main body 10, the second electrode 302 closer to the center of the second housing 301 is longer, while the first electrode 202 closer to the edge of the first housing 201 is shorter. Since the second electrode 302 closer to the center of the second housing 301 is in contact with the skin for a longer period during use, by designing the second electrode 302 closer to the center of the second housing 301 to be longer and the second electrode 302 closer to the edge of the second housing 301 to be shorter, the contact area between the multiple second electrodes 302 and the skin can be guaranteed while reducing the cost of the beauty device 100.

[0046] Furthermore, such as Figure 1 and Figure 5 As shown, the width of each first electrode 202 gradually decreases in the second direction along the direction towards the main body 10. Thus, within the front projection surface of the beauty device 100, the width of each first electrode 202 at the end adjacent to the main body 10 is smaller, while the width of the end of each first electrode 202 away from the main body 10 is larger. This arrangement ensures sufficient contact area between the multiple first electrodes 202 and the skin while reducing the size of the first electrodes 202, further reducing the cost of the beauty device 100.

[0047] And / or, each first electrode 202 protrudes from at least one surface in the second direction in a direction away from the center of the first housing 201. Specifically, each first electrode 202 protrudes from one surface in the second direction in a direction away from the center of the first housing 201 (not shown in the figure); or, both surfaces of each first electrode 202 protrude from both sides in the second direction in a direction away from the center of the first housing 201 (e.g., ...). Figure 1As shown in the figure, the first electrode 202 is roughly crescent-shaped at this time.

[0048] According to some embodiments of the present invention, a plurality of second electrodes 302 include a first sub-electrode 3021 and a second sub-electrode 3022. The first sub-electrode 3021 is disposed adjacent to the recess 3011, and the second sub-electrode 3022 is disposed adjacent to the edge of the second housing 301. The first sub-electrode 3021 protrudes from at least one surface in the second direction in a direction toward the center of the second housing 301. Specifically, each first sub-electrode 3021 protrudes from one surface in the second direction in a direction toward the center of the second housing 301 (not shown in the figure); or, each first sub-electrode 3021 protrudes from both surfaces in the second direction in a direction toward the center of the second housing 301 (e.g., ...). Figure 3 and Figure 5 As shown in the figure, the first sub-electrode 3021 is roughly crescent-shaped, protruding toward the center of the second housing 301.

[0049] And / or, the second sub-electrode 3022 protrudes from at least one side surface in the second direction in a direction away from the center of the second housing 301. Specifically, each second sub-electrode 3022 protrudes from one side surface in the second direction in a direction toward the center of the second housing 301 (not shown in the figure); or, each second sub-electrode 3022 protrudes from both sides surface in the second direction in a direction toward the center of the second housing 301 (e.g., ...). Figure 3 and Figure 5 As shown in the diagram, the second sub-electrode 3022 is roughly crescent-shaped, protruding away from the center of the second housing 301. That is, the protruding direction of the second sub-electrode 3022 is opposite to that of the first sub-electrode 3021. This design ensures that the second nursing head 30 has a better visual effect.

[0050] According to other embodiments of the present invention, the first nursing head 20 further includes a third electrode 203. The third electrode 203 includes a connecting segment 2031 and a plurality of arc-shaped segments 2032. The connecting segment 2031 is connected to the plurality of arc-shaped segments 2032. The connecting segment 2031 is located on the side of the first electrode 202 adjacent to the main body 10. Each arc-shaped segment 2032 is disposed between two adjacent first electrodes 202, and each arc-shaped segment 2032 extends circumferentially along the first housing 201. (Refer to...) Figure 1 , Figure 2 and Figure 4There can be one third electrode 203, which can be located in the middle of the first housing 201. The shape of each arc segment 2032 is approximately the same as that of the first electrode 202. The connecting segment 2031 is located adjacent to the main body 10, so that the shape of the third electrode 203 is approximately W-shaped. Thus, by setting the third electrode 203 on the first housing 201, the electrode area on the first housing 201 is increased, the space utilization of the first housing 201 is improved, and the arrangement of the first electrode 202 and the third electrode 203 is more compact.

[0051] According to some embodiments of the present invention, the first nursing head 20 further includes a plurality of fourth electrodes 204, which are respectively disposed on both sides of the first housing 201 in the second direction, and at least two of the plurality of fourth electrodes 204 have different lengths. Figure 7 As shown, there can be six fourth electrodes 204, which are divided into two groups and respectively located on both sides of the plurality of first electrodes 202. At least two of the three fourth electrodes 204 located on the same side can have different lengths, while the four electrodes 204 in both groups are the same; or, the three fourth electrodes 204 located on the same side can have the same length, while the four electrodes 204 in the two groups have different lengths. Therefore, when a user needs to perform skincare on the sides of the nose, the fourth electrodes 204 can be used, allowing them to adhere to the skin on both sides of the nose for better facial skincare.

[0052] According to some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, each first electrode 202 includes an electrode body 2021 and at least one conductive post 2022. The conductive post 2022 is disposed on the side of the electrode body 2021 adjacent to the first housing 201, and passes through the first housing 201 to be connected to the circuit board of the main body 10. A plurality of through holes 2011 are formed on the first housing 201, and the plurality of through holes 2011 correspond one-to-one with a plurality of first electrodes 202. A groove 2021a is formed on one of the inner sidewall of the through hole 2011 and the outer peripheral wall of the electrode body 2021, and a protrusion 2012 is provided on the other of the inner sidewall of the through hole 2011 and the outer peripheral wall of the electrode body 2021. The protrusion 2012 fits into the groove 2021a.

[0053] For example, in Figure 3 and Figure 4In the example, the electrode body 2021 has a sheet-like structure. Two conductive posts 2022 are provided on one side of the electrode body 2021 in the thickness direction. Each conductive post 2022 extends towards the main body 10. A groove 2021a is formed on the outer peripheral wall of the electrode body 2021, extending circumferentially along the electrode body 2021. A through hole 2011 adapted to the shape of the electrode body 2021 is formed on the first housing 201. A protrusion 2012 is provided on the inner sidewall of the through hole 2011, extending circumferentially along the through hole 2011. During installation, the protrusion 2012 fits into the groove 2021a to fix the first electrode 202 onto the first housing 201 and electrically connect the conductive post 2022 to the circuit board, facilitating power supply to the first electrode 202, ensuring normal operation of the first electrode 202, and improving the connection reliability between the first electrode 202 and the first housing 201.

[0054] In some optional embodiments, the first housing 201 and / or the second housing 301 are transparent housings. A phototherapy component is housed within the main body 10, connected to the circuit board of the main body 10. The light emitted by the phototherapy component is emitted through the transparent housing. The phototherapy component can emit light of different colors. Through the combination of light and electrodes, the beauty device 100 can achieve functions such as oil control, anti-inflammation, promoting collagen regeneration, reducing redness, soothing sensitive skin, improving redness or erythema, relieving swelling, anti-wrinkle and anti-aging, fading spots, and brightening skin tone.
