Description

[Technical Field]

[0001] The present invention relates to a beauty device that cleanses and massages the face by supplying current to a brush and vibrating the brush. [Background technology]

[0002] Conventionally, beauty devices that cleanse or massage the face or the like by supplying an electric current to a brush and vibrating the brush are known (see, for example, Patent Document 1). The beauty device described in Patent Document 1 has a conductive brush mounted on the end of a cylindrical main body. An electric current is supplied to this brush to improve the massage and cleansing effects by EMS (Electrical Muscle Stimulation), and the brush vibrates when driven by a motor. A user can easily cleanse or massage the face or the like by pressing this brush against the face or the like. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Utility Model Registration No. 3232761 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-mentioned beauty device, the brush is pressed against the face with the brush surface facing in a fixed direction. As a result, the brush surface may not face the direction corresponding to the area being pressed, resulting in uneven pressing force, such as a strong pressing force in one part of the brush and a weak pressing force in another part. Such uneven pressing force is undesirable because it leads to uneven cleansing and massaging effects.

[0005] Therefore, in order to solve the problems present in the prior art, the present invention aims to provide a beauty device that can press a brush for cleaning or massaging against a target area on the face or the like while suppressing unevenness in the pressing force. [Means for solving the problem]

[0006] A beauty device that solves the above-mentioned problems is characterized by comprising: a brush formed of a conductive flexible material and having a shape in which multiple flexible protrusions are arranged along a brush surface; a head frame that holds the brush with the multiple flexible protrusions exposed to the outside; a motor that extends a vibration output shaft in a direction perpendicular to the brush surface and vibrates the vibration output shaft to vibrate the brush via the head frame; a circuit board that uses the brush as an output electrode and supplies at least one current of an EMS current for EMS output and an ion current for ion derivation to the brush; a main frame that houses the motor and the circuit board with the vibration output shaft protruding to the outside; and a head swing module that is arranged between the main frame and the head frame, is connected to the vibration output shaft, and holds the head frame in a state in which it can move in a swing direction that tilts the brush surface relative to an orthogonal plane perpendicular to the vibration output shaft. [Effects of the Invention]

[0007] According to the above-described beauty device, the brush for cleaning or massaging can be pressed against the pressed area on the face or the like while suppressing unevenness in the pressing force. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, an embodiment of a beauty device will be described with reference to the drawings.

[0010] Fig. 1 is a perspective view showing a beauty device according to one embodiment, Fig. 2 is a front view of the beauty device shown in Fig. 1 as seen from the direction of arrow V11 in Fig. 1, Fig. 3 is a side view of the beauty device shown in Fig. 1 as seen from the direction of arrow V12 in Fig. 1, and Fig. 4 is a rear view of the beauty device shown in Fig. 1 as seen from the direction of arrow V13 in Fig. 1.

[0011] The beauty device 1 of this embodiment is a device that a user holds in their hand and presses against the face or the like to cleanse or massage. It includes a head 11 that is pressed against the face or the like, and a main body 12 that the user grips. The head 11 includes a brush 111 having an array of flexible protrusions 111a, with the flexible protrusions 111a exposed to the outside. The brush 111 is made of a conductive flexible material and functions as an output electrode for EMS and ions to improve the cleansing effect, as described below, and vibrates when driven by a motor from the main body 12. Furthermore, the head 11 is connected to the main body 12 so as to be movable in a swing direction D11 indicated by an arrow in FIGS. 1 to 4. The swing direction D11 is the direction in which the brush surface on which the flexible protrusions 111a are arranged tilts in the up, down, left, and right directions when viewing the brush 111.

[0012] FIG. 5 is an exploded perspective view of the head shown in FIGS. 1 to 4. FIG.

[0013] The head 11 will be described in detail below with reference to Figures 1 to 5, including Figure 5. The head 11 includes a brush 111, a head frame 112, a first magnet 113, a second magnet 114, and a magnet fixing part 115.

[0014] The brush 111 is a member made of a conductive flexible material and has a shape in which multiple flexible protrusions 111a are arranged along a circular brush surface. In this embodiment, the brush 111 is composed of a pair of brush sections 111-1 that divide the brush surface into two. An example of the conductive flexible material referred to here is conductive silicone. Each brush section 111-1 has multiple flexible protrusions 111a protruding from a semicircular plate section 111b that defines the brush surface. Furthermore, a power receiving terminal 111c is protruding from the back surface of the plate section 111b, opposite the side where the flexible protrusions 111a protrude, and receives the EMS current supplied from the main body 12 in the brush section 111-1.

[0015] Head frame 112 is a member made of insulating resin that holds brush 111 with multiple flexible protrusions 111a exposed to the outside. Head frame 112 has a truncated conical cylindrical shape that is open on the bottom side, and brush 111 is held on the upper surface side of head-side top plate 112a.

[0016] The first magnet 113, the second magnet 114, and the magnet fixing part 115 are parts for holding the brush cover 13 (described below) on the head frame 112. The magnet fixing part 115 is a disk part that holds a pair of brush portions 111-1 that make up the brush 111 in a circularly combined state. The first magnet 113 is fixed to this magnet fixing part 115. Meanwhile, a second magnet 114 is fixed to the back surface side of the head-side top plate 112a of the head frame 112, and the brush cover 13 is detachably held by the magnetic attraction between the first magnet 113 and the second magnet 114.

[0017] The beauty device 1 of this embodiment also includes a brush cover 13, which is not shown in Figures 1 to 4. The brush cover 13 is made of metal and has a cone shape, and is detachably attached to the head 11 via a first magnet 113 and a second magnet 114 so that the bottom opening 13a accommodates exposed portions of the multiple flexible protrusions 111a inside. The brush cover 13 is detached from the head 11 when the beauty device 1 is in use, and is attached to the head 11 when it is not in use.

[0018] FIG. 6 is an exploded perspective view of the main body shown in FIGS. 1 to 4. FIG.

[0019] The main body 12 will be described in detail below with reference to Figures 1 to 6, including Figure 6. The main body 12 includes a motor 121, a main circuit board 122, an LED (Light Emitting Diode) board 123, a battery 124, and a main body frame 125.

[0020] The motor 121 is a component that has a vibration output shaft 121a extending in a direction D12 intersecting the brush surface of the brush 111 of the head 11, and vibrates the vibration output shaft 121a, thereby vibrating the brush 111 via the head frame 112. The motor 121 is fixed to the inside of the main body frame 125 via a resin motor cover 121b. The vibration output shaft 121a of the motor 121 protrudes outside the main body frame 125 toward the head 11, while being waterproofed by a motor waterproof ring 121c.

[0021] The main circuit board 122 is a PCBA (Printed Circuit Board Assembly) that drives the motor 121 and supplies EMS current and ion current to the brush 111 of the head 11, using the brush 111 as an output electrode for the EMS and ions. The main circuit board 122 has a pair of EMS output pin terminals 122a that correspond to a pair of brush portions 111-1 that make up the brush 111. The pair of EMS output pin terminals 122a are connected to power receiving terminals 111c of the pair of brush portions 111-1. The main circuit board 122 supplies EMS current to the pair of brush portions 111-1 of the brush 111 via the EMS output pin terminals 122a and the power receiving terminals 111c. During ion extraction, a circuit is formed in which the pair of brush portions 111-1 serve as negative electrodes to supply ion current.

[0022] The LED board 123 is a PCBA that lights up various parts of the main body 12 by lighting up LEDs. The LED board 123 is installed inside the main body frame 125 near the end on the head 11 side, and is formed in a C-shape so as not to interfere with other components built into the main body 12, such as the motor 121 and the main circuit board 122.

[0023] The battery 124 is a rechargeable battery when depleted, and supplies power to electrical components such as the motor 121, the main circuit board 122, and the LED board 123. The battery 124 is disposed so as to overlap a portion of the main circuit board 122.

[0024] The main body frame 125 is an insulating resin case that houses built-in components such as the motor 121, the main circuit board 122, the LED board 123, and the battery 124. The main body frame 125 includes a front case 125a, a rear case 125b, and a main body lid 125c.

[0025] As shown in FIGS. 1 to 4, a power / mode switching button 125a-1 is attached to the outer wall on the front side of the front case 125a. This power / mode switching button 125a-1 is held by a button holder 125a-2 from inside the front case 125a, with a button operation unit 125a-1a visible through an opening in the front case 125a. This power / mode switching button 125a-1 is used to turn on the power and to switch between the EMS operation mode and the ion operation mode. Mode switching occurs each time the power / mode switching button 125a-1 is pressed briefly after power is turned on. The EMS operation mode is a mode in which the motor 121 vibrates the brush 111 and outputs EMS from the brush 111. The ion operation mode is a mode in which the brush 111 vibrates and ions are extracted from the brush 111.

[0026] 1, 3, and 4, rear case 125b has a charging port 125b-1 for battery 124 formed on the outer side wall so that it can be opened and closed by a USB (Universal Serial Bus) cover 125b-2. A charging board 125b-4 is installed inside rear case 125b, with a USB charging connector 125b-3 visible through charging port 125b-1. Charging board 125b-4 is a PCBA on which the USB charging connector 125b-3 is mounted and which is connected to the electrodes of battery 124.

[0027] 3 and 4, the rear case 125b is provided with a positive ion electrode 125b-5 made of a conductive material on the outer wall on the rear side. When used in the ion operation mode, when the user touches this positive electrode 125b-5, an electric circuit is formed in which an ion current flows through the positive electrode 125b-5, the user, and the negative electrode, with the brush 111 of the head 11 acting as the negative ion electrode. In this embodiment, the positive electrode 125b-5 is also used as a logo plate bearing the manufacturer's logo.

[0028] The front case 125a and the rear case 125b are assembled by ultrasonic bonding, and in combination with waterproofing treatment using the motor waterproof ring 121c and the like, the main body 12 of the beauty device 1 of this embodiment achieves a waterproof level of IPX7.

[0029] 1 to 4, the head 11 is connected to the main body 12 in a state where it can move in the swing direction D11. This connection is made by the configuration described below.

[0030] FIG. 7 is a schematic diagram showing a configuration in which a head is connected to the main body shown in FIGS. 1 to 4 in a state in which the head can move in the swing direction.

[0031] 7, the head 11 is connected to the main body 12 by a single component, the head swing module 14. The head swing module 14 is disposed between the main body frame 125 and the head frame 112. Specifically, the head swing module 14 is disposed inside the head frame 112 so as to be sandwiched between the main body-side top plate 125c-1 of the main body cover 125c of the main body frame 125 and the head-side top plate 112a of the head frame 112. The head swing module 14 has a central connecting portion 141 connected to the vibration output shaft 121a of the motor 121 and holds the head frame 112 in a state where it can move in the swing direction D11. This swing direction D11 is a direction in which the brush surface defined by the plate portions 111b of the pair of brush portions 111-1 constituting the brush 111 is inclined with respect to an orthogonal plane P11 perpendicular to the vibration output shaft 121a.

[0032] The head swing module 14 also has a connecting portion 141 with the vibration output shaft 121a, and multiple (four in this embodiment) arms 142 extending from the connecting portion 141a along the brush surface. The extending end portion 142a of each arm 142 is connected to a connecting boss 112b protruding from the head-side top plate 112a of the head frame 112. In this head swing module 14, a portion of the connecting portion 141a and at least one of the four arms 142 are formed from deformable soft silicone, and the other portions are formed from hard silicone. The head swing module 14 enables the head frame 112, and thus the head 11, to move in the swing direction D11 by deformation of the portion formed from soft silicone.

[0033] According to the beauty device 1 of the embodiment described above, the brush 111 held by the head frame 112 vibrates while outputting EMS and deriving ions, thereby cleansing or massaging the face or other area against which the brush 111 is pressed. At this time, the head swing module 14 disposed between the main body frame 125 and the head frame 112 holds the head frame 112 in a movable state in a swing direction D11, which tilts the brush surface. Because the head swing module 14 holds the head frame 112, when a user presses the brush 111 against the face or other area, the head frame 112 moves in the swing direction D11, thereby orienting the brush surface in a direction corresponding to the area to be pressed. As a result, unevenness in the pressing force from the brush 111 to the area to be pressed is suppressed. Thus, according to the beauty device 1 described above, the brush 111 for cleansing or massaging can be pressed against the area to be pressed on the face or other area with suppressed unevenness in the pressing force.

[0034] In this embodiment, the head swing module 14 enables movement of the head frame 112 by deformation of at least one of the connecting portion 141 with the vibration output shaft 121a and the four arms 142 connected to the head frame 112. With this configuration, the configuration of the head swing module 14 that enables movement of the head frame 112 is simpler than, for example, a gear mechanism, and requires fewer parts. This makes it possible to effectively reduce the size of the mechanism related to the movement of the head frame 112.

[0035] In this embodiment, when the user touches the positive ion electrode 125b-5 in the ion operation mode, the following electric circuit is formed: That is, with the brush 111 as the negative ion electrode, an electric circuit is formed in which an ion current flows through the positive electrode 125b-5, the user, and the brush 111. With this configuration, by utilizing the user's natural action of gripping the main body 12, the electric circuit for flowing the ion current can be effectively formed without the user being particularly aware of it.

[0036] In this embodiment, the head frame 112 detachably holds the brush cover 13 via the first magnet 113 and the second magnet 114. This configuration makes it easy to attach and detach the brush cover 13, which is frequently attached and detached.

[0037] In this embodiment, the brush 111 is composed of a pair of brush sections 111-1 that divide the brush surface into two. With this configuration, the direction of the pair of brush sections 111-1 when pressed against the face or the like can be slightly changed between them, so that the pressing force against the pressed area can be more evenly suppressed.

[0038] The above-described embodiments are merely examples of beauty devices, and the beauty devices are not limited to these embodiments. In other words, the beauty devices can be used by making appropriate modifications according to the intended use, etc.

[0039] For example, in the above-described embodiment, as an example of a beauty device, a beauty device 1 whose specific external shape is shown in Figures 1 to 4 is illustrated. However, the beauty device is not limited to this, and any external shape can be adopted.

[0040] Furthermore, in the above-described embodiment, as an example of a head swing module, a head swing module 14 having a connecting portion 141 with the vibration output shaft 121a and four arms 142 connected to the head frame 112 is exemplified. This head swing module 14 enables movement of the head frame 112 by deformation of at least one of the connecting portion 141 and the four arms 142. However, the head swing module is not limited to this. The head swing module may be configured to movably hold the head frame using, for example, a gear mechanism, as long as it holds the head frame in a state where it can move in the swing direction in which the brush surface is tilted. However, as described above, the head swing module 14 that enables movement of the head frame 112 by deformation of at least one of the connecting portion 141 and the arms 142 can effectively reduce the size of the mechanism related to the movement of the head frame 112. Note that, although not specified here, the deformable portions of the head swing module 14 may be only one of the connecting portion 141 and the arms 142, or both. Furthermore, the number of arms 142 is not limited to four, and may be any number other than four.

[0041] In the above-described embodiment, as an example of a beauty device, a beauty device 1 is illustrated as having an ion operation mode, in which, when a user grips the main body 12 and touches the ion positive electrode 125b-5, an electrical circuit is formed through which an ion current flows through the positive electrode 125b-5, the user, and the brush 111. However, beauty devices are not limited to this, and even when having an ion operation mode, any configuration may be adopted for the electrical circuit through which the ion current flows. However, as described above, the above configuration, which utilizes the user's natural movement of gripping the main body 12, allows the electrical circuit for flowing the ion current in the ion operation mode to be effectively configured without the user being particularly aware of it. Note that in the present embodiment, as an example of a beauty device, a beauty device 1 is illustrated as having both an EMS operation mode and an ion operation mode and is used by switching between the modes. However, the beauty device is not limited to this, and may operate in only one of the modes.

[0042] In the above-described embodiment, the brush 111 is illustrated as an example of a brush, which is configured with a pair of brush portions 111-1 that divide the brush surface into two. However, the brush is not limited to this, and may be formed as a single, undivided part. However, as described above, the brush 111 configured with a pair of brush portions 111-1 can press the pressed area while further suppressing unevenness in the pressing force.
