Description

[Technical Field]

[0001] The present invention relates to a beauty tool set comprising a beauty tool equipped with a brush for treating hair and scalp, and a base for supporting the beauty tool. [Background technology]

[0002] 2. Description of the Related Art Beauty devices for treating hair and scalp are equipped with means having various functions. For example, there are negative ion generating means, red light irradiating means, EMS generating means, etc. (see Patent Documents 1 to 3).

[0003] Negative ions bind to water molecules in the air, so by attaching negative ions to hair, the amount of moisture on the surface of the hair can be increased, providing a moisturizing effect to the hair. Negative ions also have the effect of removing positively charged odor particles, dust, pollen, bacteria, etc. from the surface of the hair and scalp, activating hair and scalp cells to make hair shiny and prevent split ends, and neutralizing positively charged hair with negative ions to prevent tangling between the hair and brush.

[0004] When red light with a wavelength of about 630 nm is irradiated onto the skin, it activates the fibroblasts in the dermis, which together with the epidermis make up the skin, reacts with melanin, and is said to be effective in removing deep blemishes and also promotes blood circulation, bringing radiance and firmness to the skin. As a means of irradiating the red light, a commercially available LED capable of emitting red light with a wavelength of 630 nm can be used.

[0005] EMS (Electrical Muscle Stimulation) stimulates muscles and motor nerves by passing EMS current through the facial skin and scalp, causing the muscles to contract, just like actual exercise. It has the effect of burning excess fat, tightening muscles, eliminating sagging, restoring firm, beautiful skin, and smoothing the flow of blood and lymph to remove facial swelling.

[Figure 3] Cross-section of the cradle [Figure 4] Top view of the cradle [Figure 5] Cross-sectional view of a beauty device [Figure 6] A plan view of the beauty tool, seen from the side where the brush is arranged. [Figure 7] FIG. 1 is a cross-sectional view showing a beauty tool set in which a beauty tool is placed on a cradle; [Figure 8] Diagram showing brush mounting structure DETAILED DESCRIPTION OF THE INVENTION

[0011] An embodiment of the present invention will be specifically described with reference to the drawings. FIG. 1 is a perspective view of a beauty tool set of the present invention, which comprises a cradle and a beauty tool placed on the cradle, and FIG. 2 is a perspective view of the cradle. Here, 1 is a cradle and 11 is a beauty tool. As will be described later, the beauty tool 11 is composed of a main body 12 and a gripping part 13. When using the beauty tool 11, the user can grip the gripping part 13 to treat the hair and scalp, and when not in use, the beauty tool 11 can be placed on the receiving stand 1. The cradle 1 serves as a stand on which the beauty tool 11 is placed, and also has the function of irradiating the underside of the main body of the beauty tool 11 with deep ultraviolet light having sterilizing properties to keep it clean when the beauty tool 11 is placed on it.Furthermore, the cradle 1 can also accommodate a secondary battery 20 such as a lithium battery housed in the beauty tool 11 and have the function of charging the secondary battery. The secondary battery 20 supplies power to drive means for performing various functions provided to the beauty tool.

[0012] The cradle 1 comprises a long, narrow, roughly bowl-shaped case 2 with an opening and legs 3 that support the case 2. When the beauty tool 11 is placed on the cradle 1, the main body 12 of the beauty tool can be detachably combined with the case 2 by fitting the frame of the opening of the case 2 of the cradle into the frame of the main body 12. At this time, the grip 13 of the beauty tool protrudes from the case 2 of the cradle. Therefore, when using the beauty tool 11, the beauty tool can be easily removed from the cradle 1 by grasping the grip 13 of the beauty tool. A magnet 10 may be attached to the tip of the case part 2 of the receiving stand, and a magnet 31 may be attached to the tip of the main body part 12 of the beauty tool, so that when they are combined, the magnets come together and the magnetic force prevents the main body part 12 of the beauty tool from slipping off the case part 2 of the receiving stand.

[0013] The legs 3 of the cradle support the case 2 from below, so that the cradle 1 can be placed on a table or shelf in a stable state. In the embodiment shown in FIG. 1, the case part 2 is supported by two legs 3, but it is sufficient if the case part 2 can be supported stably on a surface such as a table surface and can remain stable even when a beauty tool 11 is placed on the cradle 1.

[0014] In FIG. 1, the beauty tool 11 is held in the case 2 of the receiving stand at an angle so that the grip 13 side is higher than the main body 12 side. However, by changing the shape of the legs 3, the beauty tool 11 may be held at an angle so that the main body 12 side is higher than the grip 13 side, or the case 2 may be held so that the beauty tool 11 is horizontal. The case 2 and the legs 3 may be integrally molded or bonded together to form the cradle 1, or the cradle 1 may be an assembled type consisting of the case 2 and the legs 3.

[0015] As shown in FIGS. 3 and 4, a partition plate 4 is attached to the case portion 2 of the cradle, dividing the interior space of the case portion 2 into two spaces, an upper space and an lower space. The upper space, i.e., the space with an open top and a partition plate 4 at the bottom, accommodates a group of brushes 16 arranged on the underside of the beauty tool main body 12 when the beauty tool 11 is placed on the cradle 1. In the space below, i.e., the space surrounded by the partition plate 4 and the case part 2, a board 6 equipped with a UV-LED 5, which is a deep ultraviolet irradiation means capable of emitting deep ultraviolet rays (UV-C) with a wavelength of around 275 nm, which is effective for sterilization, is stored and screwed to the partition plate 4.

[0016] Two holes are formed in the partition plate 4, and the UV-LEDs 5 are fitted into the respective holes. The light-emitting parts of the UV-LEDs 5 are visible through the holes, allowing deep ultraviolet light to be irradiated at a wide angle toward the space above. Although one UV-LED 5 may be used (in this case, one hole is formed in the partition plate 4), in the embodiment shown in Figures 3 and 4, two UV-LEDs are installed to enable irradiation over a wider area.

[0017] Beauty tools become dirty as they are used, and bacteria and viruses may be present on the hair and scalp of people who return from going out. Therefore, beauty tools that have come into contact with the hair or scalp must be sterilized and disinfected to keep them clean. Deep ultraviolet rays (UV-C ultraviolet rays) are ultraviolet rays with wavelengths of 100 to 280 nm that have a strong effect of destroying the DNA of bacteria and viruses, making them suitable for sterilization and disinfection.

[0018] As shown in Figures 2(b) and 3, the cradle 1 has a DC jack (power outlet) 7 provided in the case part 2 between the two legs 3, and an angled plug 8 with a 90° bent tip of the AC adapter can be inserted into this DC jack 7 from a commercial power source. The positive terminal and ground terminal of the DC jack 7 are electrically connected by wiring to the positive input terminal and ground terminal, respectively, of the circuit mounted on the substrate 6. Direct current from the plug 8 of the AC adapter inserted into the DC jack 7 passes through the circuit on the substrate 6 and is supplied to the UV-LED 5, which is the deep ultraviolet ray irradiation means, causing the light-emitting part to emit light, and the deep ultraviolet ray is irradiated toward the underside of the main body 12 on which the brush of the beauty device is disposed. The mounting position of the DC jack 7 is not limited to the position shown in FIG. 2, and the shape of the plug of the AC adapter is not limited to the one shown in FIG.

[0019] Next, a case will be described in which the cradle 1 is provided with a function of storing the secondary battery 20 housed in the beauty tool 11 and charging the secondary battery. As shown in FIG. 4, the cradle 1 has two charging pins 9 (positive and ground) at one end of the case 2 (the end that receives the tip of the beauty tool main body 12, opposite the gripping end, when the beauty tool 11 is placed on the cradle 1). On the other hand, as will be described later, the beauty tool main body 12 has two holes for charging contacts 27 (positive and ground) that receive each pin of the two charging pins 9. When the beauty tool 11 is placed on the cradle 1, the positive and ground charging pins 9 of the cradle 1 are inserted into and make contact with the holes for the positive and ground charging contacts 27 of the beauty tool main body 12, respectively.

[0020] When the beauty tool 11 is placed on the cradle 1 with the AC adapter plug 8 inserted into the DC jack 7, the positive charging pin 9 of the cradle 1 comes into contact with the positive charging contact 27 of the beauty tool main body 12, and direct current converted from alternating current by the AC adapter flows through the wiring on the board 6, via the positive charging pin 9, and into the charging circuit for the secondary battery housed in the beauty tool main body 12, starting to charge the secondary battery 20 in the main body 12. This charging circuit is mounted on the connection board 23, which will be described later. As will be described later, the start and completion of charging of the secondary battery 20 can be indicated by lighting an indicator LED provided on the cover 15 of the beauty tool. Alternatively, an indicator LED 29 may be provided in a position near the cap 18 inside the grip portion 13 of the beauty tool, and this LED may be lit while the secondary battery is being charged, allowing confirmation through the translucent cap 18 that the secondary battery is being charged.

[0021] A current detection circuit is formed on the board 6 of the cradle 1, and the terminals of this circuit are wired and electrically connected to the ground-side charging pin 9. When the beauty tool 11 is placed on the cradle 1, current flows from the wiring on the board 6 through the positive-side charging pin to the secondary battery 20 in the main body 12, just as during charging. This current then flows through the ground-side charging contact 27 and the ground-side charging pin 9 to the current detection circuit. When the current detection circuit detects this current, it determines that a beauty tool has been placed on the cradle 1, and direct current from the plug 8 passes through the circuit on the board 6 to supply power to the UV-LED 5, which is the deep-ultraviolet light emitting means, causing the light-emitting unit to emit light, and deep-ultraviolet light is irradiated toward the underside of the main body 12 on which the brush of the beauty tool is disposed.

[0022] The irradiation time of the light-emitting portion of the UV-LED 5 is set on a timer in a microcomputer chip mounted on the substrate 6, and is usually about 15 to 20 seconds. During irradiation with deep ultraviolet light (UV-C), the underside of the beauty tool main body 12 and the brushes 16 are sterilized, allowing the beauty tool 11 to be kept clean. Deep ultraviolet rays are irradiated while the beauty tool 11 is placed on the cradle 1, so there is no leakage of deep ultraviolet rays. Furthermore, even if the beauty tool is removed from the cradle during irradiation, the UV-LEDs 5 stop lighting and the irradiation of deep ultraviolet rays also stops when the current detection circuit on the board 6 no longer detects current, so it is safe for the human body. As with charging the secondary battery 20, lighting of the UV-LED 5 can be indicated by providing an indicator LED on the cover 15 of the beauty tool and lighting this indicator LED.

[0023] Next, the beauty tool 11 will be described. As shown in Figures 5 and 6, the beauty tool 11 comprises a main body 12 and a grip 13. A base frame 14 and a cover 15 that covers the base frame 14 are combined to form the main body 12 and grip 13, each having an internal space. A brush 16 is disposed on the base frame 14, which forms the underside of the main body 12. A cylindrical case 17 is attached to the grip 13 to make it easier to grip, and the end is covered with a cap 18. Figure 7 shows a cross-sectional view of the beauty tool 11 placed on the cradle 1.

[0024] 6, in this embodiment, the beauty tool 11 is formed by the base frame 14 and the cover 15, both of which have a rice scoop-like shape in plan view, but the shape is not limited to this. Also, the main body 12 and the gripping part 13 can be made of frames each having an internal space, and the ends of both can be screwed together to form the beauty tool 11.

[0025] 8(a), the brush 16 is disposed such that its base portion is fitted into a portion of the base frame 14 that forms the underside of the main body 12, and the portion excluding the base portion protrudes downward from the base frame 14. To more reliably fix the base portion of the brush 16, a reinforcing plate 19 having a hole formed therein through which the base portion of the brush 16 passes may be attached to the underside of the base frame 14 of the main body.

[0026] As already described, when the beauty tool 11 is not being used for hair styling or treatment, it is placed on the cradle 1. A magnet 31 may be attached to the tip of the beauty tool main body 12, so that when the beauty tool is placed on the cradle 1, the magnet 31 and the magnet 10 attached to the cradle mate, and the magnetic force prevents the beauty tool main body 12 from slipping out of the case 2 of the cradle.

[0027] As can be seen from FIG. 5, the beauty tool body 12 accommodates a secondary battery 20 such as a lithium battery, a negative ion generating means 21, a blower fan 22, a connection board 23, and an operation board 24.

[0028] The negative ion generating means 21 emits negative ions toward the group of brushes 16 protruding from the lower surface of the base frame 14 of the main body, and a blower fan 22 is used to facilitate the emission of negative ions. Various methods for generating negative ions, such as corona discharge, are known, but here, a negative ion generating device that generates negative ions by applying a voltage to carbon fiber can be used. Such devices are commercially available and can be activated with a voltage of approximately 3 to 5 V to release negative ions. The components can also be manufactured in small sizes, with dimensions of approximately 8 mm x 15 mm x 18 mm. Similarly, a commercially available small electric blower fan, for example, one measuring approximately 15 mm x 15 mm x 4 mm, can be attached and used.

[0029] The negative ion generating means 21 and the blower fan 22 can be provided in a portion of the beauty tool main body 12 near the grip side, or straddling the main body 12 and the grip part 13, or fixed to the grip part 13 with ribs or the like. At the portion where the base frame 14 rises in front of the negative ion generating means 21, holes 32 are formed through which gas containing negative ions can pass toward the group of brushes 16, and negative ions can be emitted laterally toward the group of brushes 16 arranged on the underside of the base frame 14 of the main body 12.

[0030] Negative ions have a cleansing effect on hair and scalp, removing positively charged odor particles, dust, pollen, bacteria, etc., and have the effect of activating cells. They also electrically neutralize hair that is positively charged with static electricity, preventing it from getting tangled with the brush. Therefore, when the beauty tool 11 is used for hair styling or treatment, by operating the negative ion generating means 21 and the blower fan 22, gas containing negative ions can be made to flow toward the group of brushes 16 arranged on the base frame 14, thereby exerting the above-mentioned effects on the hair and scalp.

[0031] The main body 12 of the beauty tool may house an LED capable of emitting red light with a wavelength of approximately 630 nm as the red light irradiation means 26. In this case, by forming a hole in the center of the base frame 14 of the main body and arranging the LED of the red light irradiation means 26 in this hole so that the light-emitting part of the LED is visible through the hole, red light with a wavelength of approximately 630 nm can be irradiated from the main body 12 of the beauty tool in the direction of the brush 16 disposed thereon. A commercially available power LED can be used for this LED. In the embodiment shown in FIG. 5, two holes 30 are provided in the base frame 14 and two LEDs of the red light irradiation means 26 capable of emitting red light are fitted into the holes 30 to widen the irradiation range, but one LED of the red light irradiation means 26 capable of emitting red light may also be fitted into the holes 30.

[0032] When the main body 12 is provided with an LED as the red light irradiation means 26, a recess is formed in the center of the base frame 14 of the main body 12 in the axial direction of the beauty tool 11, as shown in Figures 5 and 6, to prevent the light-emitting part of the LED from becoming dirty and cloudy during use of the beauty tool 11. A transparent or translucent resin plate 25 can be inserted into the recess, and red light can be emitted through the resin plate 25. Therefore, when the beauty tool main body 12 is provided with an LED as the red light irradiation means 26, as can be seen from Figure 6, multiple brushes 16 are arranged on the base frame 14 of the main body 12 so as to roughly surround the transparent or translucent resin plate 25.

[0033] The beauty device can also be equipped with EMS (i.e., Electrical Muscle Stimulation) functionality. In this case, as shown in FIG. 8(b), the brush 16 is used as a treatment electrode to pass EMS current to the facial skin and scalp. That is, the tip of the brush 16 is an electrode made of a conductive material such as metal or resin, and one end of the conductor inside the brush is connected to this electrode, and the other end of the conductor is soldered (connected) to a circuit mounted on a board (hereinafter referred to as the "connection board") 23 disposed on the main body 12. The conductor inside the brush 16 is covered with an insulating plastic material. The connection board 23 may be equipped with a programmed circuit so that the combination of the brushes 16 to be paired is determined in advance and an EMS current (low frequency pulse current) flows between the electrodes of the paired brushes.

[0034] The beauty tool main body 12 houses a secondary battery 20, which is placed on the base frame 14. The secondary battery 20 is fixed to the base frame 14 by a plurality of ribs or the like. The secondary battery 20 supplies power to drive the means for performing the functions provided to the beauty tool 11 (such as the negative ion generating means 21, the blower fan 22, and the red light irradiating means 26), power to drive the display LED, and power to operate the control unit for controlling these.

[0035] As already described, charging current is supplied to the secondary battery 20 from the AC adapter plug 8 inserted into the DC jack 7 via the charging pin 9 and charging contact 27 provided on the cradle 1. 6, the main body 12 of the beauty tool is provided with two charging contacts 27 (positive and ground) that respectively receive the two charging pins 9 (positive and ground) of the case 2 of the cradle. When the beauty tool 11 is placed on the cradle 1, the positive and ground charging pins 9 of the cradle 1 are inserted into and contact with the holes of the positive and ground charging contacts 27 of the main body 12 of the beauty tool, respectively, and current flows through a charging circuit mounted on the connection board 23, thereby charging the secondary battery 20. The two charging contacts 27 are cylindrical bodies and are attached to the tip of the main body 12 so as to penetrate the base frame 14 .

[0036] An operation board 24 is housed inside the main body 12 of the beauty tool, and an operation button (switch button) 28 that is operated by the user is provided on the cover 15 of the main body 12. Circuit elements such as a CPU and memory are mounted on the operation board 24, and based on an operation signal from the operation button 28 and in accordance with a program stored in the memory, it can control the on / off operation of the negative ion generating means 21 and the blower fan 22, which are means for realizing the functions assigned to the beauty tool 11, the LED of the red light emitting means 26 (illumination), and the EMS.

[0037] In the embodiment of Fig. 5, two switch buttons are provided, and in this case, one switch button can be used to input on / off, and the other switch button can be used to select the strength of the operation mode, etc. For example, it can be used to switch between modes such as the strength of the EMS current.

[0038] A plurality of display LEDs 29 that indicate the above-mentioned on / off by lighting up or flashing may be arranged near the operation button 28 of the cover 15. A plurality of display LEDs 29 are shown in FIG. 1. The lighting up or flashing of the display LEDs 29 can also be performed based on the program of the operation board 24. Similarly, the lighting up of the LED of the deep ultraviolet irradiation means 5 of the receiving stand 1 can also be indicated by the display LEDs 29. Furthermore, an LED 29 for display may be provided in a position near the cap 18 inside the grip portion 13 of the beauty tool, and the cap 18 may be made of a material such as translucent plastic, so that this LED lights up while the secondary battery is charging, allowing the user to confirm through the cap 18 that the secondary battery is being charged.
