Description

Technical Field

[0001] This invention relates to a beauty device that applies cosmetic effects to the user's face or head, and particularly to a technique for applying electro-cosmetic effects from the needles of a comb provided with the beauty device. Background Technology

[0002] Previously, there were known beauty devices that used pulsed currents through the skin to induce muscle contractions (EMS: Electrical Muscle Stimulation), thereby promoting lymphatic flow, providing fatigue recovery, or strengthening muscles.

[0003] In addition, Patent Document 1 discloses a vibrating hairbrush that stimulates the scalp through vibration while combing the hair. According to the vibrating hairbrush developed by the applicant in this case, the scalp can be stimulated from multiple directions, and it can also vibrate at high frequency to achieve a variety of effects.

[0004] Patent document 2 discloses a needle for a massager. Although the needle is not aimed at the scalp, multiple needles make even contact with the soft skin or muscles of the cheeks, etc., and can apply comfortable vibration and electrical stimulation to relieve fatigue without discomfort.

[0005] In this invention, a helical spring is provided that surrounds the base end of a plurality of needles and applies force outward to each of the plurality of needles.

[0006] Furthermore, the head of the beauty device disclosed in Patent Document 3 is configured as follows: it 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. The elastic insertion part includes two ends in the elastic direction, one end of which is inserted into the head and electrically connected to the conductive structure, and the other end of which is electrically connected to the electrical connection part.

[0007] Patent documents 4 to 6 disclose a structure in which a spiral spring is provided at the base of each needle of the hair comb.

[0015] Patent Document 6: Japanese Patent Application Publication No. 2000-262637 Summary of the Invention

[0016] The problem the invention aims to solve

[0017] According to the aforementioned prior art, a method is described in which a spiral spring is inserted into the base of the comb's needle body, allowing the needle body to move in and out, or energizing the spiral spring. On the other hand, in this construction, since a point of different rigidity is created between the base and the needle body, there is a problem that the needle body may break or become unable to bend flexibly, resulting in a poor user experience.

[0018] In addition, in a structure where an electrode area is set at the front end of the needle, it is necessary to stably supply sufficient power to the electrode area. However, even if a helical spring is set at the base to energize it, the power path to the front end cannot be guaranteed.

[0019] Furthermore, in the comb-shaped beauty devices that have been provided in the past, in addition to having electrodes at the front end of the needle body to perform electro-beautification effects, they do not provide the function of a regular hair comb or a simple structure corresponding to various beauty effects, nor do they provide a structure that can be used on areas other than the scalp or hair.

[0020] Therefore, the object of the present invention is to create a comb-shaped beauty device with excellent structure to apply electro-beauty effects, and to provide a technology that can be adapted to various applications.

[0022] To address the aforementioned issues, the present invention provides the following beauty device.

[0050] Hereinafter, embodiments of the present invention will be described based on the examples shown in the accompanying drawings. However, the embodiments are not limited to the following description. Figure 1This is a perspective view of the beauty device (1) of the present invention. The generally rod-shaped main body (10) of the beauty device is composed of a gripping part (11) for the user to hold on, and a comb-shaped comb part (12) for applying beauty effects on the other side.

[0051] In this embodiment, the comb attachment (20) is configured to be detachable from the comb part (12) and can be freely replaced according to the type of beauty function or the area of ​​application.

[0052] However, the comb part (12) of the present invention may also directly include a comb-like body, and is not necessarily limited to a detachable structure. The comb accessories described below can all be structures that are fixedly installed on the comb part (12).

[0053] The comb accessory (20) has multiple needles (21). At the front end of each needle (21) is a front end (22), which is an electrode area that can conduct electricity to the user's target area. The front end (22) is made of metal, but it can also be made of conductive resin or the like.

[0054] Figure 2 A cross-sectional view illustrating the needle body structure of the beauty device is shown. In this embodiment, the needle body (21) is configured as a generally cylindrical columnar portion (24) of silicone resin erected from a base (23) which serves as a common base of multiple needle bodies.

[0055] A helical spring (25), which serves as an elastic body, is inserted into the cylinder of the columnar portion (24). The outer diameter of the helical spring (25) is approximately the same as the inner diameter of the columnar portion (24), and when the columnar portion (24) flexes, the tension of the helical spring (25) can achieve appropriate flexibility. At the same time, the helical spring (25) helps to improve the durability of the columnar portion (24).

[0056] Conventionally, structures have been provided with a helical spring at the base of the columnar portion. In this case, the helical spring is a structure that elastically supports the movement of the columnar portion. On the other hand, in the present invention, by embedding the spring within approximately the entire length of the columnar portion (24), both elasticity and reinforcement in the bending direction are simultaneously achieved.

[0057] The generally cylindrical columnar portion (24) extends into the thickness portion of the base (23), through which the helical spring (25) passes and is inserted. Furthermore, the end (25a) of the helical spring (25) protrudes from the back of the base (23).

[0058] In the end (25a) of the helical spring (25), the outer diameter of the helical spring (25) is larger than the inner diameter of the columnar portion (24). Therefore, the helical spring (25) will not be pulled into the columnar portion (24) and will remain exposed.

[0059] Furthermore, this end (25a) makes electrical contact with the circuit board (26) on the back side. Contacts are provided on the circuit board (26) at positions corresponding to the helical spring (25), allowing power to be supplied from an energizing circuit (not shown) provided in the main body (10). As is well known, the energizing circuit consists of a power source supplied with electricity by a rechargeable battery, battery, or power adapter, and a control circuit that controls the current, voltage, etc. However, in this invention, the energizing circuit is not necessarily limited to the structure provided in the main body (10), and may also be provided within the comb accessory (20). Alternatively, only the power source may be provided in the main body (10), or a portion of the control circuit may be distributed between the main body and the comb accessory.

[0060] A reinforcing resin plate (27) is superimposed on the surface of the substrate (23) opposite to the circuit board (26), resulting in the substrate (23) being clamped. The reinforcing resin plate (27) not only prevents deformation of the substrate (23), but also strengthens the root of the columnar portion (24) due to its thickness. The needle (21) is prevented from bending from the root by the reinforcing resin plate (27), thereby preventing breakage or other damage. The reinforcing resin plate (27) is constructed with holes in a flat resin surface corresponding to the positions of the columnar portion (24).

[0061] An extension (22a) at one end of the front end portion (22) is inserted into the inner circumference of the other end (25b) of the helical spring by a predetermined length. The extension portion (22a) is a rod-shaped portion with a smaller diameter than the front end portion (22) and makes electrical contact with the helical spring (25). Thus, an electrical path is formed from the circuit board (26) through the helical spring (25) to the front end portion (22).

[0062] That is, in this invention, the helical spring (25) not only simultaneously provides elasticity and reinforcement in the bending direction, but also functions as an electrical path from the circuit board (26) to the electrode area, i.e., the front end (22). In this respect, when the columnar portion (24) flexes, it has the disadvantage of being prone to poor contact due to wire breakage in ordinary wires. On the other hand, in the structure of this invention, by compressing and inserting the helical spring (25), even if the needle body (21) flexes significantly, it can elongate and maintain electrical contact at both ends, thus achieving an electrical path with low resistance and no risk of wire breakage.

[0063] In this invention, any component other than a helical spring (25) can be used as the elastomer. For example, a rod-shaped body made of conductive resin or a leaf spring made of metal can also be used.

[0064] A locking portion (22b) with a diameter larger than the aforementioned minor diameter rod is formed at the midpoint of the extension (22a) of the front end portion (22). The locking portion (22b) engages with a groove (24a) provided at the corresponding position of the columnar portion (24). During manufacturing, with the front end portion (22) in a predetermined position, silicone resin is allowed to flow into the mold, and molding is performed with the locking portion (22b) engaging with the groove (24a). The locking portion (22b) is stably fixed to the columnar portion (24) by the protrusion and the recess on the front end side.

[0065] The front end (22) and the columnar part (24) can also be integrally formed by injection molding or the like without creating gaps. As a result, liquid will not seep into the interior through the gap between the front end (22) and the columnar part (24), so even when using it with liquids such as beauty serums applied to the scalp, corrosion of the contact points between the coil spring (25) and the front end (22) can be prevented, and an increase in resistance can be prevented, thus achieving a stable effect over a long period of time.

[0066] In this embodiment, the length of the extension (22a) from the locking portion (22b) is 3 mm, and the length of the electrode region at the front end (22) is 4.6 mm. The length of the extension (22a) is 1 to 10 mm, preferably 2 to 6 mm. The length of the electrode region is such that it remains in contact with the skin surface even when the columnar portion (24) flexes significantly, preferably about 2 to 6 mm, and particularly preferably 3 to 5 mm.

[0067] Figure 3 This is a front view of the beauty device of the present invention. Figure 4 This is a right view of the beauty device. As shown in the figure, the comb attachment (20) of this embodiment consists of three rows of longitudinally arranged needles (21), with the central row arranged in a straight line and the rows on both sides arranged outwards from the middle. Furthermore, in order to apply the beauty effect of EMS from the front end (22), low-to-medium frequency electrical stimulation is applied.

[0068] like Figure 4 As can be seen, the comb attachment (20) shown in this embodiment is configured such that the upper and lower needles (21) are relatively high, while the central part is relatively low. The virtual line connecting the front end of the needle (21) is cup-shaped, so that when it touches the face, the front end (22) can be evenly pressed against the surface.

[0069] exist Figure 4 The image shows the main body (10) standing upright on the charging base (13). The charging base (13) charges the rechargeable battery inside the main body (10) to supply the required power.

[0070] The assembly and disassembly mechanism of the comb accessory (20) is explained.

[0071] exist Figure 2 In the middle, the comb attachment (20) is separated from the comb part (12) at the position of the dotted line (A). The comb attachment (20) includes a base (23), a circuit board (26) and an attachment base (28) on its back side.

[0072] Figure 5 This is an explanatory diagram illustrating the shape of the comb accessories. Figure 6 This is an explanatory diagram showing the assembly and disassembly parts of the comb accessory.

[0073] like Figure 5 As shown, in this invention, multiple comb attachments can be interchanged. In addition to the facial comb attachment (20) shown in the above embodiment, a comb attachment (30) for scalp care can also be used.

[0074] Figure 6 This is an explanatory diagram showing the assembly and disassembly parts of the comb accessory.

[0075] The comb part (12) of the main body (10) is a roughly elliptical recess (120) in which an accessory base (28)(38) is embedded.

[0076] A magnetic body is provided so that the recess (120) and the accessory base (28)(38) are magnetically attracted to each other. When they get close enough, the comb accessory is installed with a click.

[0077] Furthermore, the recess (120) is provided with main body side electrodes (121)(122)(123), and the accessory base (28) is provided with accessory side electrodes (280)(281)(282), which together constitute the energized part.

[0078] The electrode area of ​​the needle body (1) is powered from the main body (10) through the energizing part.

[0079] Light-emitting diodes (124) are provided on both sides of the recess (120). For example, by using the light-emitting diodes to apply red light to the skin surface, a cosmetic effect such as promoting blood circulation can be applied.

[0080] Furthermore, the recess (120) of the main body (10) is equipped with a vibration mechanism. The vibration mechanism is constructed by incorporating a general vibration motor and transmitting the vibration to the comb attachment (20).

[0081] Alternatively, the vibration mechanism can be located on the comb accessory side. In this case, the vibration motor inside the comb accessory is driven by power supplied through the aforementioned energizing unit.

[0082] As described above, the present invention allows for the application of various cosmetic effects by changing the comb attachment. For example, Figure 7This is a comb attachment (30) for use on the scalp. Comb your hair upwards like a hairbrush to care for your scalp.

[0083] In this embodiment, a low-hardness silicone comb is used, which gently conforms to the scalp by reducing the number of needles with electrode areas. The silicone needles are approximately 4 mm in diameter, preferably in the range of 3 to 6 mm.

[0084] Furthermore, in this invention, the needles of the comb accessory may not contain a conductive elastomer, depending on the application.

[0085] For the scalp, a weak current can flow through the front electrode (32) for iontophoresis. Additionally, a pulse wave of 30V to 50V can be applied to the skin surface for stretching. As shown in the figure, a pair of adjacent front electrodes (32) are used as positive and negative electrodes, and current is applied between the electrodes. For example, adjacent front electrodes (32) are set to opposite polarities. In practice, this can be divided into a right half and a left half, and an upper half and a lower half.

[0086] At the same time, it is preferable to apply vibration to the scalp from a vibration mechanism.

[0087] on the other hand, Figure 8 The comb attachment (20) shown is used to apply a cosmetic effect to the muscles of the face or neck and shoulders. For example, the needle is placed on the temporalis muscle, which extends from the cheekbone to the temporalis fascia, for massage. If the temporalis muscle is tense and stiff, it will stretch the face laterally, causing the face to appear larger or wider. By relaxing the temporalis muscle, the zygomaticus major muscle, and the zygomaticus minor muscle together, the face will appear smaller and can be tightened.

[0088] In this embodiment, an example is shown where the central column of the front end (22) is designated as the - pole and the columns on both sides are designated as the + pole (a method of distinguishing polarity when AC is applied). By concentrating the same polarity in each area, the user's tactile sensation can be enhanced.

[0089] Of course, the polarity configuration is arbitrary; it can be alternating or divided into right and left halves, or upper and lower halves.

[0090] To suit such facial areas, the comb attachment (20) employs flexible needles (21) to apply a current suitable for EMS while maintaining soft contact. The current flowing through the EMS can be low-frequency (10Hz-100Hz) or mid-frequency (1kHz-10kHz) alternating current, especially 1kHz alternating current. Alternatively, it can be used in conjunction with or as a substitute for EMS to apply microcurrents to the muscles.

[0091] The grip (11) of the beauty device (1) is equipped with operation buttons (14) and (15) for operation. Using the operation button (14) on the top, the intensity level of the beauty effect can be switched, for example, the applied voltage of EMS can be switched, such as 30V in level 1, 40V in level 2, and 50V in level 3.

[0092] Furthermore, the optimal EMS mode of the beauty device is as follows. The device features two modes: a scalp mode targeting the scalp and a face mode targeting the face or neck and shoulders, which can be switched in combination with levels 1 to 3 mentioned above. Additionally, a vibration mode that activates the vibration mechanism has been added. By using the vibrations together, appropriate stimulation can be applied in both the scalp and face modes.

[0093] Additionally, the operation button (15) below can be used to switch the power on / off or switch modes. As for modes, they can be switched according to the body part, such as a mode suitable for the head, a mode suitable for the face, or a mode suitable for the shoulders and neck, or according to beauty effects such as EMS, microcurrent, light irradiation, and vibration.

[0094] In this invention, an appropriate current can also be automatically supplied from the main body (10) through the installed comb accessory. For example, an IC chip can be included in the comb accessory, and based on the power supply conditions such as voltage and frequency stored in the IC chip, the control circuit of the main body (10) reads the information of the IC chip and supplies power accordingly.

[0095] Alternatively, contacts corresponding to the type can be set in the comb accessory. The type of comb accessory with the control circuit of the main body (10) can be identified by the position of the contacts or whether they are conductive, and power can be applied accordingly.

[0096] When the type of comb accessory is automatically identified, the operation buttons (14) and (15) can also be switched to the corresponding type.

[0097] In this way, not only can the comb accessories be easily installed and removed, but also, through automatic power supply, anyone can easily use it without any knowledge or experience.

[0098] However, as mentioned above, the pulse wave specifications are such that at low voltages below 100V, especially below 30V to 50V, and with microcurrents below 1mA, there is almost no muscle contraction. Therefore, it has the advantage of being easy to use for users who are not comfortable with electrical stimulation from EMS.

[0099] Furthermore, the present invention can be energized with the following current. That is, the voltage under no-load conditions can be kept in the range of 200V to 800V by using a weak current smaller than about 1mA from the front electrode (32), thereby enhancing the sensation of the weak current and allowing massage to be performed while feeling the massage area. In addition, low frequency can be used to promote muscle contraction, resulting in a tightening effect or promoting blood circulation. A mode for electrical stimulation via conventional EMS can also be provided.

[0100] At voltages below 100V, the sensation is no different from that of a typical microcurrent; however, above 800V, the stimulation becomes too strong. Therefore, a range of 200V to 800V, especially 400V to 800V, is appropriate.

[0101] In addition, according to the applicant's experiments, when used on the scalp, and when used on the face or neck, a pulse wave in the range of 12.5 to 50 Hz is preferred.

[0102] By setting a relatively high voltage, one can experience a sensation or stimulation similar to low-frequency electrical stimulation, thus enabling an effective massage that does not cause boredom.
