Description

[Technical Field]

[0001] The present invention relates to a cosmetic device. [Background technology]

[0002] A skin treatment device that applies RF (Radio Frequency) energy to the skin of a user has been proposed (see, for example, Patent Document 1).

[0003] This skin treatment device is equipped with multiple linearly arranged electrodes, and when in use, these electrodes are placed on the skin and a predetermined pulse current is passed through them for a predetermined period of time, thereby raising the temperature of the moisture contained in the skin.

[0004] In this case, if current continues to flow through the electrodes, the skin temperature will rise too much, so after the temperature has risen to a certain level, it is necessary to repeatedly turn the pulse current on and off to maintain a constant skin temperature.

[0005] [Patent Document 1] U.S. Patent No. 9,844,682 B2 Summary of the Invention [Problem to be solved by the invention]

[0006] Incidentally, when electrodes are brought into contact with the skin, it is expected that a single device will be able to cover both large areas such as the cheeks and chin, and small areas such as under the eyes and at the corners of the eyes.

[0007] However, to cover both wide and narrow areas, a certain number of electrodes are required, and the electrodes must be divided according to the area covered. Furthermore, to make the device more compact, the treatment surface must be made smaller. On the other hand, changing the size of the electrodes according to the area covered is costly. Furthermore, during assembly, it is necessary to ensure that the electrodes corresponding to the wide and narrow areas do not come into contact with each other.

[0008] The present invention has been made in consideration of the above circumstances, and aims to provide a beauty device in which the treatment surface is made small and the electrodes do not interfere with each other. [Means for solving the problem]

[0009] In order to solve the above problems, the present invention employs the following means. The cosmetic device of the present invention is a cosmetic device that heats the biological tissue of a person being treated, and is equipped with a treatment section having a treatment surface on which are arranged a plurality of electrodes that come into contact with the biological tissue and output RF, and the treatment surface comprises a first treatment surface having a predetermined surface area and a second treatment surface having a surface area smaller than that of the first treatment surface, and the first treatment surface and the second treatment surface are connected in a roughly V-shape when viewed from the side.

[0010] In addition, in the beauty device of the present invention, the treatment section comprises a flexible substrate having a planar flat portion and a curved portion arranged in an approximately V-shape, and the electrodes have the same shape and are connected to the flexible substrate along the approximately V-shaped direction of the curved portion.

[0011] In addition, the cosmetic device of the present invention has an electrode that comprises a contact portion that contacts the biological tissue and a support portion whose one end is connected to the contact portion, the contact portion and the support portion are connected in a roughly L-shape when viewed from the side, and a notch portion that is connected to the flexible substrate is formed on the side surface of the other end of the support portion. [Effects of the Invention]

[0012] According to the present invention, it is possible to reduce the size of the treatment surface while preventing the electrodes from interfering with each other. [Brief explanation of the drawings]

FIG. DETAILED DESCRIPTION OF THE INVENTION

[0014] An embodiment of the present invention will be described with reference to FIGS. The facial beauty device (beauty device) 10 according to this embodiment is a facial beauty device that heats the skin (biological tissue) of a person to be treated (not shown), and comprises a main body 11 and a cap (not shown) that is detachable from the main body 11.

[0015] The main body 11 is provided with an operation switch 12 operated by the practitioner or the patient. The main body 11 is provided with a treatment surface 16 on which are arranged a plurality of electrodes 13 that come into contact with the skin and output RF, and a temperature sensor 15 that measures the skin temperature.

[0016] The main body 11 also includes a bendable flexible substrate 18 having a planar flat portion 18A and a generally V-shaped bend portion 18B. Integrated circuits such as an MPU (Micro Processing Unit) and an FPGA (Field Programmable Gate Array), not shown, are arranged on the flexible substrate 18, and realize or execute various information processing functions and actions during treatment.

[0017] The treatment surface 16 comprises a first treatment surface 16A having a predetermined surface area capable of contacting wide areas such as the cheeks and chin, and a second treatment surface 16B having a surface area smaller than that of the first treatment surface 16A capable of contacting narrow areas such as under the eyes and around the corners of the eyes. When viewed from the operation switch 12 side, the first treatment surface 16A and the second treatment surface 16B are connected in a generally V-shape.

[0018] The multiple electrodes 13 further include electrodes 13A, 13B, 13C, 13D, 13E, and 13F arranged on the first treatment surface 16A, and electrodes 13G and 13H arranged on the second treatment surface 16B. Each electrode 13 has approximately the same shape and includes a contact portion 20 that extends in one direction and comes into contact with the skin, and a support portion 21 having one end 21A connected to the contact portion 20 and the other end 21B extending in a direction approximately perpendicular to the contact portion 20, with the contact portion 20 and the support portion 21 connected in a substantially L-shape in side view. The surface of the contact portion 20 is formed as a curved surface.

[0019] The support portions 21 of the electrodes 13F and 13G have cutouts 22 formed on the side surfaces at the other ends 21A thereof, which are soldered to the flexible substrate 18. The electrodes 13A, 13B, 13C, 13D, 13E, and 13H have the other ends 21B soldered to the flexible substrate 18. Each electrode 13 is arranged so that the contact portion 20 protrudes from the treatment surface 16.

[0020] The bent portion 18B of the flexible substrate 18 includes a first bent portion 18B1 formed by bending a portion of the flat portion 18A approximately vertically so as to face the first treatment surface 16A, and a second bent portion 18B2 formed by bending a portion of the flat portion 18A approximately vertically so as to face the second treatment surface 16B. That is, the bent portion 18B is formed and arranged in a substantially V-shape in a side view, similar to the treatment surface 16.

[0021] The first bent portion 18B1 has a plurality of first holes 23A into which the other ends 21B of the support portions 21 of the electrodes 13A, 13B, 13C, 13D, and 13E are inserted, and a first protrusion 23B that is inserted into the notch 22 of the electrode 13F. The second bent portion 18B2 has a second protrusion 23C that is inserted into the notch 22 of the electrode 13G, and a second hole 23D into which the other end 21B of the support portion 21 of the electrode 13H is inserted. The first holes 23A are spaced apart at approximately equal intervals from one another and aligned along a central axis C1 shared with the first protrusion 23B. The central axis C1 and the central axis C2 shared by the second protrusion 23C and the second hole 23D are spaced apart by a distance equal to or greater than the width of the support portion 21.

[0022] Next, the operation of the cosmetic device 10 according to this embodiment will be described together with the assembly method. The other end 21B of each support portion 21 of electrodes 13A, 13B, 13C, 13D, and 13E is soldered to the first hole 23A, and the other end 21B of support portion 21 of electrode 13H is soldered to the second hole 23D. Also, the first protrusion 23B is inserted into the notch 22 of electrode 13F, and the second protrusion 23C is inserted into the notch 22 of electrode 13G, and they are soldered together.

[0023] At this time, the central axes C1 and C2 are arranged not to intersect by being spaced apart by a distance equal to or greater than the width dimension of the support portion 21. Therefore, the other ends 21B of the support portions 21 of the electrodes 13F and 13G arranged near the boundary between the first bent portion 18B1 and the second bent portion 18B2 do not come into contact with each other.

[0024] According to this facial beauty device 10, even if the entire device is made smaller, it can be accommodated with electrodes 13 of approximately the same shape, and even if the electrodes 13 have approximately the same shape, they can be prevented from interfering with each other when connected to a flexible substrate 18 that is bent in an approximately V-shape when viewed from the side.

[0025] The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention. [Explanation of symbols]
