Abstract
Description
Technical Field
[0001] The present invention relates to a beauty device that has a beauty effect on an action site such as a user's face or head, and particularly relates to a technique for exerting an electrical beauty effect from the pin bodies of the brush provided in the beauty device.
Background Art
[0002] Conventionally, there are known beauty devices that pass pulsed electricity through the skin to cause muscle contraction movement (EMS: Electrical Muscle Stimulation), thereby promoting the flow of lymphatic fluid to perform treatments such as fatigue recovery or to strengthen muscles.
[0003] Also, Patent Document 1 discloses a vibrating hairbrush that stimulates the scalp by vibration while performing brushing. According to this vibrating hairbrush by the applicant of the present case, it is possible to apply stimulation to the scalp from various directions, and it is also possible to vibrate at a high frequency, obtaining various effects.
[0004] Although Patent Document 2 is not targeted at the scalp, it discloses a pin head for a massager that can uniformly contact soft skin and muscle undulations such as the cheeks with a plurality of pins, giving a comfortable vibration and electrical stimulation without a sense of discomfort to recover fatigue and the like. In the present invention, a coil spring that surrounds the base ends of a plurality of pins and biases each of the plurality of pins outward is provided.
[0005] Also, the head of the beauty device disclosed in Patent Document 3 includes a head, an elastic insertion part, and an electrical connection part that is electrically connected to an external circuit structure. A conductive structure is formed inside the head, and the elastic insertion part includes both ends in the elastic direction. One end is inserted into the head and electrically connected to the conductive structure, and the other end is electrically connected to the electrical connection part.
[0006] Patent Documents 4 to 6 disclose a configuration in which a coil spring is provided at the base of each pin body of a hairbrush. [Prior art documents] [Patent Documents]
[0007] [Patent Document 1] Japanese Patent Publication No. 2013-188250 [Patent Document 2] Patent No. 5789064 [Patent Document 3] No. 3226151 publication [Patent Document 4] No. 3036599 publication [Patent Document 5] Japanese Patent Publication No. 2000-140131 [Patent Document 6] Japanese Patent Publication No. 2000-262637 [Overview of the Initiative] [Problems that the invention aims to solve]
[0008] According to the above-mentioned conventional technology, a coil spring is inserted at the base of the brush's pin body to allow the pin body to extend and retract, and current is conducted through this coil spring. However, in such a structure, a difference in rigidity is created between the base and the pin body, which can lead to the pin body breaking or the pin body not bending flexibly, resulting in a poor user experience.
[0009] Furthermore, in a configuration where an electrode region is provided at the tip of the pin body, it is necessary to stably supply sufficient power to the electrode region. However, even if a coil spring is provided at the base and current is passed through it, it was not possible to secure a current path to the tip.
[0010] Furthermore, conventional brush-shaped beauty devices, while equipped with electrodes at the tips of the pins to perform electrical beauty treatments, do not offer the functionality of a regular hairbrush or a simple configuration that can accommodate various beauty treatments. Nor do they offer a configuration that can be used on areas other than the scalp and hair.
[0011] Therefore, the present invention aims to create a brush-shaped beauty device with an excellent structure for exerting electrical beauty effects, and to provide a technology that can be used for various applications. [Means for solving the problem]
[0012] To solve the above problems, the present invention provides the following beauty device. According to a first embodiment of the present invention, a beauty device is provided comprising a plurality of flexible pins, a base body that serves as a common base for the plurality of pins, and a circuit board, wherein each pin has a substantially cylindrical columnar portion erected from the base body and a conductive tip portion provided at the tip of the columnar portion, and further comprises a conductive elastic body provided within the cylinder of the columnar portion along the longitudinal axis, and the circuit board is provided with contacts corresponding to the position of the elastic body, with one end of the elastic body compressed and in contact with the contact, and the other end of the elastic body electrically connected to the tip portion.
[0013] According to a second embodiment of the present invention, one end of the elastic body may be exposed from the back surface of the base body.
[0014] According to a third embodiment of the present invention, the base body further comprises a reinforcing plate provided on the side opposite to the circuit board, wherein the reinforcing plate has a structure in which a hole corresponding to the position of the columnar portion is opened.
[0015] According to a fourth embodiment of the present invention, the elastic body may be a coil spring.
[0016] According to a fifth embodiment of the present invention, the contact may be integrally formed with the circuit board. [Effects of the Invention]
[0017] The present invention, with the above configuration, provides the following effects. By installing a conductive elastic body along the axial direction of the pin body, the pin body has flexible flexibility, and stable power supply is achieved by energizing the electrode region through the elastic body. At the same time, according to the present invention, the beauty effect at each action site can be maximized by an optimal energization mode.
[0018] In addition, by providing a beauty device composed of a main body and a brush attachment detachable from the main body, various functions can be provided by replacing the brush attachment. At the same time, according to the structure of the brush attachment of the present invention, power can be supplied from the main body to the pin body in a reliable and simple configuration.

Modes for Carrying Out the Invention
[0020] Hereinafter, embodiments of the present invention will be described based on the examples shown in the drawings. Note that the embodiments are not limited to the following. FIG. 1 is a perspective view of a beauty device (1) according to the present invention. The beauty device is composed of a grip portion (11) that a user grips on one side of a substantially rod-shaped main body (10), and a brush-shaped brush portion (12) that applies a beauty effect on the other side.
[0021] In this embodiment, the brush attachment (20) is detachably attached to the brush section (12), allowing the brush attachment to be freely replaced depending on the type of beauty treatment and the area of application. However, the brush portion (12) in the present invention may be directly equipped with a brush-like body, and is not necessarily limited to a detachable configuration. The brush attachments described below may all be fixed to the brush portion (12).
[0022] The brush attachment (20) comprises a pin body (21) having numerous pins. The tip of the pin body (21) has a tip portion (22) which is an electrode area that can conduct electricity to the user's working area. The tip portion (22) is made of metal, but may be made of a conductive resin or the like.
[0023] Figure 2 shows a cross-sectional view illustrating the structure of the pin body of the beauty device. In this embodiment, the pin body (21) is constructed by erecting a substantially cylindrical columnar portion (24) from the base body (23) using silicone resin, with a base body (23) serving as the common base for multiple pin bodies. The pin having an electrical conduction area consists of a tip portion (22) and a columnar portion (24).
[0024] A coil spring (25) is inserted inside the columnar section (24) as an elastic body. The outer diameter of the coil spring (25) is approximately the same as the inner diameter of the columnar section (24), and the tension of the coil spring (25) provides appropriate flexibility when the columnar section (24) bends. At the same time, the coil spring (25) also contributes to improving the durability of the columnar section (24).
[0025] Conventionally, coil springs have been provided in which a coil spring is installed at the base of the columnar portion. In that case, the coil spring is configured to support the extension and retraction of the columnar portion elastically. On the other hand, in the present invention, the coil spring is installed inside the columnar portion (24) along its substantially entire length, thereby simultaneously achieving elasticity in the bending direction and reinforcement.
[0026] The roughly cylindrical columnar portion (24) penetrates through to the thickness of the base body (23), and the coil spring (25) is inserted and fitted through to this thickness. The end (25a) of the coil spring (25) is exposed from the back surface of the base body (23).
[0027] At the end (25a) of the coil spring (25), the outer diameter of the coil spring (25) is made larger than the inner diameter of the columnar portion (24). Therefore, the coil spring (25) is not pulled into the columnar portion (24) and remains exposed.
[0028] Furthermore, this end (25a) makes electrical contact with the circuit board (26) on the back side. The circuit board (26) is provided with contacts corresponding to the position of the coil spring (25), and is energized from an energizing circuit (not shown) provided in the main body (10). As is well known, the energizing circuit consists of a power supply such as a rechargeable battery, a battery, or a power adapter, and a control circuit that controls the current, voltage, and other characteristics. In this invention, the energizing circuit is not necessarily limited to being provided in the main body (10), but may also be provided in the brush attachment (20). Alternatively, only the power supply may be provided in the main body (10), or a part of the control circuit may be distributed between the main body and the brush attachment.
[0029] The base body (23) has a reinforcing resin plate (27) placed on the side opposite to the circuit board (26) mentioned above, resulting in the base body (23) being sandwiched. The reinforcing resin plate (27) not only prevents the base body (23) from deforming, but also reinforces the base of the columnar part (24) due to its thickness. The reinforcing resin plate (27) prevents the pins from bending at the base, thereby preventing breakage and other damage. The reinforcing resin plate (27) has a structure in which holes corresponding to the positions of the columnar part (24) are opened in a flat resin.
[0030] An extension (22a) from one end of the tip (22) is inserted through the inner circumference of the other end (25b) of the coil spring for a predetermined length. The extension (22a) is a rod-shaped extension with a smaller diameter than the tip (22) and is in electrical contact with the coil spring (25). This creates an electrical path from the circuit board (26) to the tip (22) via the coil spring (25).
[0031] In other words, in the present invention, the coil spring (25) not only simultaneously provides elasticity and reinforcement in the bending direction, but also acts as an electrical path from the circuit board (26) to the tip portion (22), which is the electrode region. In this respect, if the columnar portion (24) bends, a common drawback of conventional wires is that contact problems such as wire breakage are likely to occur. On the other hand, in the configuration of the present invention, by compressing and inserting the coil spring (25), even if the pin bends significantly, it expands and the electrical contact at both ends is maintained, so naturally there is no risk of wire breakage and an electrical path with low resistance can be realized.
[0032] In this invention, any material other than a coil spring (25) can be used as the elastic body. For example, a rod-shaped body made of conductive resin or a metal leaf spring can be used.
[0033] A larger diameter locking portion (22b) than the small diameter rod is formed at an intermediate position on the extension (22a) of the tip portion (22). The locking portion (22b) engages with a groove (24a) provided at the corresponding part of the columnar portion (24). During manufacturing, silicone resin is poured into the mold with the tip portion (22) in a predetermined position, and the locking portion (22b) is molded in a state where it is engaged with the groove (24a). The protrusion of the locking portion (22b) and the recess on the tip side provide stable fixation to the columnar portion (24).
[0034] The tip portion (22) and the columnar portion (24) may be integrally formed by injection molding or the like so as not to create any gaps. This prevents liquid from entering the interior through the gap between the tip portion (22) and the columnar portion (24), thus preventing contact corrosion between the coil spring (25) and the tip portion (22) and preventing an increase in electrical resistance, thus ensuring a stable effect over a long period of time, even when using it with liquids such as beauty serums applied to the scalp.
[0035] In this embodiment, the length of the extension portion (22a) beyond the locking portion (22b) is 3 mm, and the length of the electrode region of the tip portion (22) is 4.6 mm. The length of the extension portion (22a) is preferably 1 to 10 mm, more preferably 2 to 6 mm. The length of the electrode region is preferably 2 mm to 6 mm, particularly 3 mm to 5 mm, as it is the length that allows it to continue to contact the skin surface even when the columnar portion (24) is greatly bent.
[0036] Figure 3 is a front view of the beauty device according to the present invention, and Figure 4 is a right side view thereof. As shown in the figures, the brush attachment (20) of this embodiment consists of three rows of vertically arranged pins, with the central row arranged in a straight line and the rows on both sides arranged outwards in the middle. Low-to-medium frequency electrical stimulation is applied from the tip (22) to exert an EMS beauty effect.
[0037] As shown in Figure 4, the brush attachment (20) in this embodiment has high pins on the upper and lower sides, and a relatively low central section. The imaginary line connecting the tips of the pin bodies (21) is concave in a bowl shape, which allows the tips (22) to make uniform contact with the surface when applied to the face.
[0038] Figure 4 shows the main unit (10) in the charging stand (13). The charging stand (13) charges the rechargeable battery located inside the main unit (10) and supplies the necessary power.
[0039] The attachment / detachment mechanism for the brush attachment (20) will be explained. In Figure 2, the brush attachment (20) separates from the brush section (12) at the position indicated by the dashed line (A). The brush attachment (20) comprises a base body (23), a circuit board (26), and an attachment base (28) on its rear side.
[0040] Figure 5 is an explanatory diagram illustrating the configuration of the brush attachment, and Figure 6 is an explanatory diagram showing the attachment / detachment part of the brush attachment. As shown in Figure 5, the present invention allows for the use of multiple interchangeable brush attachments. In addition to the facial brush attachment (20) shown in the above embodiment, it can also be replaced with a brush attachment (30) for scalp care.
[0041] Figure 6 is an explanatory diagram showing the attachment and detachment mechanism of the brush attachment. The brush portion (12) of the main body (10) is a roughly oval-shaped recess (120), and the attachment bases (28) and (38) are fitted into this recess (120). A magnetic material is provided so that the recess (120) and the attachment base (28)(38) magnetically attach to each other, and when brought close enough, the brush attachment clicks into place.
[0042] Furthermore, the recess (120) is provided with main body side electrodes (121)(122)(123), and the attachment base (28) is provided with attachment side electrodes (280)(281)(282), and together they form an energizing section. Power is supplied from the main body (10) to the electrode area of the pin body (21) through the energizing section.
[0043] Light-emitting diodes (124) are provided on both the left and right sides of the recess (120). By irradiating the skin surface with, for example, red light using the light-emitting diodes, it is possible to exert beauty effects such as promoting blood circulation.
[0044] Furthermore, the recess (120) of the main body (10) is equipped with a vibration mechanism. The vibration mechanism consists of a general-purpose vibration motor built inside, which transmits its vibrations to the brush attachment (20). The vibration mechanism may also be provided on the brush attachment side. In this case, power is supplied through the above-mentioned energizing section to drive the vibration motor inside the brush attachment.
[0045] As described above, this invention can provide various beauty benefits by changing the brush attachment. For example, Figure 7 shows a brush attachment (30) used on the scalp. It is used to care for the scalp by raking the hair back, similar to a hairbrush.
[0046] In this embodiment, the number of pins having electrode regions is reduced, and a low-hardness silicone brush that adheres softly to the scalp is used. The silicone resin pins have a diameter of about 4 mm, and a diameter range of 3 to 6 mm is preferred. In addition, in this invention, the pin body of the brush attachment does not necessarily need to contain a conductive elastic material depending on the application.
[0047] Ion introduction can also be performed on the scalp by applying a weak current from the tip electrodes (32)(32). In addition, a 30V to 50V pulse wave can be applied to the skin surface for stretching. As shown in the figure, a pair of adjacent tip electrodes (32) are used as the positive and negative poles, and current is applied between the electrodes. As an example, adjacent tip electrodes (32) are set to opposite polarities. When performing the procedure, the area may be divided into the right half and the left half, or the upper half and the lower half. At the same time, it is preferable to apply vibrations to the scalp from the vibration mechanism.
[0048] On the other hand, the brush attachment (20) shown in Figure 8 has a cosmetic effect on the muscles of the face and décolleté. For example, the pins can be applied to the temporalis muscle, which extends from the cheekbone to the temple, for massage. When the temporalis muscle becomes tense and stiff, it pulls the face sideways, making the face appear larger and the jawline more prominent. By relaxing the zygomaticus major and minor muscles along with the temporalis muscle, the face can become smaller, firmer, and lifted.
[0049] In this embodiment, an example is shown where the central row of the tip (22) is the negative pole and the rows on both sides are the positive pole (this indicates the polarity division when AC is applied). By grouping the same polarity in each area in this way, the user's perception can be strengthened. Of course, the polarity arrangement is arbitrary; it can be alternating, or divided into right and left halves, upper and lower halves, and so on.
[0050] To suit such facial areas, the brush attachment (20) employs a pin body (21) with flexible pins, allowing for soft contact and application of a current suitable for EMS. The EMS can use low frequencies such as 10Hz to 100Hz, medium frequencies such as 1kHz to 10kHz, and especially 1kHz alternating current. Microcurrent may also be applied to the muscles in conjunction with or instead of EMS.
[0051] The gripping part (11) of the beauty device (1) is equipped with operation buttons (14) and (15) for operation. The upper operation button (14) allows switching levels such as the intensity of the beauty effect, for example, the applied voltage of the EMS can be switched to 30V at level 1, 40V at level 2, and 50V at level 3.
[0052] Furthermore, the optimal EMS modes for the beauty device are shown below. The beauty device has two modes: a scalp mode for the scalp and a face mode for the face and décolleté, which can be switched between in combination with the above levels 1 to 3. In addition, there is a vibration mode that activates the vibration mechanism. By using vibration in combination, appropriate stimulation can be provided in the scalp mode and face mode, respectively.
[0053] Additionally, the lower control button (15) can be used to turn the power on and off and switch modes. Modes can be switched according to the body part, such as a mode suitable for use on the head, a mode suitable for the face, and a mode suitable for the décolleté, or modes that correspond to the beauty effects, such as EMS, microcurrent, light irradiation, and vibration.
[0054] In this invention, the main unit (10) may be configured to automatically supply an appropriate current depending on the brush attachment to be installed. For example, the brush attachment may have an IC chip in which the conditions for supplying current, such as voltage and frequency, are stored, and the control circuit of the main unit (10) may read the information from the IC chip and supply current accordingly.
[0055] Alternatively, the brush attachment may be provided with contacts corresponding to its type, and the control circuit of the main unit (10) may determine the type of brush attachment attached based on the position of the contacts and whether or not there is conductivity, and then apply the appropriate current. If the type of brush attachment is automatically detected, the operation buttons (14) and (15) may be configured to switch accordingly.
[0056] In addition to the ease of attaching and detaching the brush attachment, the device automatically applies the appropriate power supply, making it easy for anyone to use without requiring any knowledge or experience.
[0057] Incidentally, as mentioned above, pulse waves produce almost no muscle contraction at low voltages of 100V or less, especially 30V or 50V or less, and with current values below 1mA. Therefore, it has the advantage of being easy to use for users who are uncomfortable with electrical stimulation from EMS.
[0058] In addition, the present invention can also supply the following types of current: a weak current of less than approximately 1 mA from the tip electrodes (32)(32), with the no-load voltage in the range of 200V to 800V, can be used to enhance the sensation of the weak current, allowing the user to feel the treatment area while performing the procedure. Furthermore, low frequencies can be used to stimulate muscle contraction, producing effects such as tightening and improved blood circulation. The invention may also include a mode for general EMS-based electrical stimulation.
[0059] When the voltage is lower than 100V, the sensation is no different from that of a typical microcurrent, but above 800V, the stimulation becomes too strong. Therefore, a range of 200V to 800V, and especially 400V to 800V, is preferable. Furthermore, according to the applicant's experiments, when used on the scalp, face, or décolleté, it is preferable to use pulse waves in the range of 12.5 to 50 Hz.
[0060] By using a relatively high voltage, it's possible to experience sensations and stimuli similar to low-frequency electrical stimulation, allowing for effective massage without becoming monotonous. [Explanation of Symbols]
