Description

[Technical Field]

[0001] The present invention relates to a head massager. [Background technology]

[0002] For example, Patent Document 1 discloses an electric shaver equipped with an iontophoresis device in the head that efficiently transports cosmetics such as shaving cream from the outside to the inside of the body. In the iontophoresis device of such an electric shaver, the shaving head, which is moved over the skin to which cosmetics have been applied, is provided with a plurality of adjacent poles that form a star-shaped iontophoresis device, and different potentials are applied to each pole (see FIG. 6). Furthermore, Patent Document 2 suggests that, instead of a heating means in the head, an electric shaver for skin may be equipped with an electrical muscle stimulation (EMS) effect that tightens the skin, an iontophoresis effect that moisturizes the skin as described above, an iontophoresis effect that removes dirt from the skin's pores, or a combination of these effects.

[0003] Furthermore, as shown in Patent Document 3, for example, an electric cosmetic brush device has been proposed in which a scalp care attachment and a facial care attachment can be selectively attached to the main body in order to efficiently care for both the scalp and the face. The protrusions of the bases of the scalp care attachment and the facial care attachment are fitted into grooves in the base of the main body, allowing the scalp care attachment and the facial care attachment to be selectively attached to the main body. When this is done, the interlocking shaft and the steel lid are connected, and when a weak voltage is applied to the interlocking shaft, a weak current flows through the rotating scalp care attachment or facial care attachment via the interlocking shaft and the steel lid to the scalp or face, thereby providing electrical stimulation to the scalp or face.

[0004] [Patent Document 1] Special Publication No. 2010-510821 [Patent Document 2] Japanese Patent Publication No. 2022-187098 [Patent Document 3] Patent No. 7144792 Summary of the Invention [Problem to be solved by the invention]

[0005] Even in scalp care using an electric cosmetic brush device such as that shown in Patent Document 3, there is a demand for the use of an iontophoresis device that efficiently transports nutrients contained in shampoos and the like from the outside of the body to the inside, or an ion extraction device that has the effect of removing dirt from pores.

[0006] However, when the scalp is covered with hair, the iontophoresis device and the ion derivation device cannot come into direct contact with the scalp, and there is a risk that the iontophoresis and ion derivation effects may not be reliably exerted.

[0007] In consideration of the above problems, an object of the present invention is to provide a head massager that can reliably perform ion introduction and ion extraction functions. [Means for solving the problem]

[0008] In order to achieve the above-mentioned object, the head massager of the present invention comprises a housing with an operating unit that houses a massage head drive mechanism, a drive motor that drives the massage head drive mechanism, a control unit electrically connected to the drive motor, and a secondary battery that supplies power to the drive motor and the control unit; multiple types of massage heads including an iontophoresis / ion derivation massage head that is detachably attached to the massage head drive mechanism via a connecting mechanism; a motor drive control unit connected to the control unit and controls the drive of the drive motor; an electrical muscle stimulation (EMS) control unit connected to the control unit and controls the operation of an electrical muscle stimulation (EMS) circuit unit that supplies a predetermined potential to multiple conductive silicone rubber contact pins of the multiple types of massage heads; and an iontophoresis / ion derivation control unit connected to the control unit and controls the operation of the iontophoresis / ion derivation circuit unit that supplies a predetermined potential to multiple conductive silicone rubber contact pins of the iontophoresis / ion derivation massage head, wherein the iontophoresis / ion derivation massage head has at least a magnet molded from terahertz mineral that comes into contact with the skin.

[0009] The ion introduction / ion extraction massage head may have a magnet molded from terahertz mineral that contacts the scalp, inside a plurality of contact pins made of conductive silicone rubber arranged at intervals along the circumferential direction.

[0010] The massage head drive mechanism may be composed of a plurality of gear trains. The secondary battery of the head massager may be charged via a capacitor on which the housing is placed and electrically connected. The housing may have a red light emitting diode (LED) board on its underside. The interior space of the housing may be a sealed space with a waterproof structure. [Effects of the Invention]

[0011] According to the head massager of the present invention, the ion introduction / ion extraction massage head has at least a magnet made of terahertz mineral that comes into contact with the skin, and the terahertz waves activate the movement of water molecules in the cells of the human body, thereby ensuring the ion introduction and ion extraction effects.

[0013] FIG. 2(A) shows a schematic view of an example of the head massager according to the present invention.

[0014] 2(A), the outer casing of the head massager 10 includes a resin upper shell 16 forming the top portion, a resin bottom shell 12 integrally formed with the upper shell 16 and continuing downward, and a resin disk-shaped base plate 14 joined to the lower end of the bottom shell 12 and supporting a gear box 68 (see FIG. 7), which will be described later. The upper end of the base plate 14 and the lower end of the bottom shell 12 are sealed and joined together. As a result, the internal space of the housing formed by the upper shell 16, the bottom shell 12, and the base plate 14 is made into an airtight space with a waterproof structure by a boot BO, which will be described later, so that the head massager 10 can be used simultaneously when washing hair, etc.

[0015] An operation unit 16A having a power button 16a and a mode switching button 16b is formed on the sloped surface of the upper shell 16. A battery remaining amount / charge state display unit 16B that shows the charge state of a lithium battery 64 (see FIG. 7) serving as a secondary battery, which will be described later, is formed on the part that connects the end of the sloped surface of the upper shell 16 to the reduced diameter part of the bottom shell 12. The battery remaining amount / charge state display unit 16B is formed, for example, by five light-emitting diodes (LEDs) lined up at predetermined intervals in a row.

[0016] As shown in Figures 3(A) and 7, a band-shaped first conductive member 18 is provided on the front end of the expanded section that expands radially from the center of the reduced-diameter section of the bottom shell 12, facing the operating section 16A of the upper shell 16. Furthermore, a band-shaped second conductive member 20 is provided on the back end of the expanded section of the bottom shell 12, facing the band-shaped first conductive member 18. The length of the band-shaped second conductive member 20 along the circumferential direction of the bottom shell 12 is set longer than that of the band-shaped first conductive member 18. The band-shaped first conductive member 18 and the band-shaped second conductive member 20 function as a single electrode, and the same positive or negative charge is applied to them during ion introduction control / ion extraction control, which will be described later. In the ion introduction control / ion derivation control described below, a positive or negative charge different from the charge applied to the four massage heads (ion introduction / ion derivation massage heads) 24 and the four massage heads (facial massage heads with magnets) 38 is applied to the strip-shaped first conductive member 18 and the strip-shaped second conductive member 20.

[0017] When the head massager 10 is used, the portion of the bottom shell 12 from the reduced diameter portion to the expanded diameter portion is grasped in the palm of the hand, making it easy to hold, and the band-shaped first conductive member 18 and the band-shaped second conductive member 20 are securely abutted against the fingers, respectively. This ensures that the band-shaped first conductive member 18 and the band-shaped second conductive member 20 are electrically connected to the body. On the other hand, when the fingers are separated from the band-shaped first conductive member 18 and the band-shaped second conductive member 20, the band-shaped first conductive member 18 and the band-shaped second conductive member 20 are not electrically connected to the body, and the ion introduction control / ion derivation control is automatically stopped.

[0018] As shown in FIG. 2(A), four massage heads (iontophoresis / ion derivation massage heads) 24 (see FIG. 6) are connected to the inclined rotation shafts 76 of spur gears 70G1, 70G2, 70G3, and 70G4 supported by a lower housing 68B of a gear box 68 within the base plate 14. The four massage heads (iontophoresis / ion derivation massage heads) 24 (see FIG. 6) project downward through openings 68b (see FIG. 10) in the lower housing 68B and through openings (not shown) in the base plate 14. As shown in FIG. 2(B), the connecting portions of the massage heads 24 and the inclined rotation shafts 76 are covered with boots BO, thereby sealing the openings in the base plate 14. As shown in FIG. 2(B), a decorative cover 26 is integrally formed in the center of the underside of the base plate 14, facing a red light-emitting diode (LED) board 72 fixed to the gear box 68 (described later). Between two adjacent massage heads 24 on the underside of the base plate 14 and close to the rear portion of the bottom shell 12, a pair of female connection terminals 14a, 14b are provided to which a pair of male connection terminals 28P1 and 28P2 of the charger 28 described later are respectively connected.

[0019] Inside the bottom shell 12, there are formed a drive motor 66, a gear box 68 that houses a spur gear train (see Figure 9) to which the output shaft of the drive motor 66 is connected, a control board 60 that drives and controls the drive motor 66, and a drive control component storage section that houses a lithium battery 64 as a secondary battery that supplies power to the drive motor 66 and the control board 60, etc.

[0020] An operating parts housing portion is formed inside the upper shell 16 to house the head of the drive motor 66, the touch switch board 64, and the like.

[0021] 8, the control board 60, which is supported on the periphery of each fixing screw hole of the upper housing 68A of the gear box 68, has an opening in its center through which the lower end of the drive motor 66 supported by the upper housing 68A passes, and has a connector 62C connected to one end of a flexible circuit board 62, the other end of which is connected to the touch switch board 65. In addition, a lithium battery 64, which is electrically connected to the control board 60, is fixed between the fixing screw holes in the control board 60 via a pair of locking pieces 60K. The above-mentioned strip-shaped first conductive member 18 and strip-shaped second conductive member 20 are each electrically connected to output ends of the control board 60 at the same potential via lead wires.

[0022] The touch switch board 65 has switch sections 65B corresponding to the power button 16a and mode switching button 16b, respectively, and is connected to a display board 65A on which five light-emitting diodes (LEDs) corresponding to the battery remaining capacity / charge status display section 16B are arranged at predetermined intervals. The touch switch board 65 and the display board 65A are fixed to the head of the drive motor 66 via an inclined board support plate.

[0023] As shown in Figures 8 and 9, the gear box 68 includes an upper housing 68A that supports the control board 60 and a lower housing 68B that is covered by the upper housing 68A. As shown in Figure 7, the lower housing 68B is supported on the inner periphery of the base plate 14. The upper housing 68A is fixed to the lower housing 68B by threading the machine screws BS through holes in the upper housing 68A into the female threaded holes 68FS of the lower housing 68B (see Figure 8). As a result, a plurality of gear trains that transmit the rotational force of the drive motor 66 to the four massage heads 24 are disposed in the accommodation space formed between the upper housing 68A and the lower housing 68B.

[0024] As shown in FIG. 9, the pinion gear 70G5 fixed to the output shaft 66S of the drive motor 66 is meshed with spur gears 70G6, 70G7, and 70G8. The spur gears 70G6, 70G7, and 70G8 are each rotatably supported by the lower housing 68B. The spur gears 70G6 and 70G7 are meshed with spur gears 70G1 and 70G3, which are larger than the spur gears 70G6 and 70G7. As shown in FIG. 8, the spur gears 70G1 and 70G3 each have an inclined rotation shaft 76 to which a locking claw 78N on a post sleeve 78 of the massage head 24 is detachably locked. The spur gear 70G8 is meshed with spur gears 70G9 and 70G10. The spur gears 70G9 and 70G10 are meshed with spur gears 70G2 and 70G4, which are larger than the spur gears 70G9 and 70G10, respectively. The spur gears 70G2 and 70G4 each have an inclined rotation shaft 76 to which a locking claw 78N on a post sleeve 78 of the massage head 24 is detachably engaged. The spur gears 70G1, 70G2, 70G3, and 70G4 each have the same module. The spur gears 70G6, 70G7, 70G8, 70G9, and 70G10 each have the same module.

[0025] As a result, in Figure 9, for example, when viewed from above, if pinion gear 70G5 is rotated clockwise, spur gears 70G1 and 70G3 are rotated clockwise, and spur gears 70G2 and 70G4 are rotated counterclockwise.

[0026] The connecting mechanisms including the inclined rotation shafts 76 of the spur gears 70G1, 70G2, 70G3, and 70G4 have the same structure, so only the connecting mechanism of the spur gear 70G4 will be described, and descriptions of the connecting mechanisms of the other spur gears 70G1, 70G2, and 70G3 will be omitted.

[0027] The inclined rotation shaft 76 of the spur gear 70G4 is integrally formed at a predetermined inclination angle with respect to the rotation shaft connecting portion of the spur gear 70G4. An O-ring OL is provided in a groove at the upper end of the inclined rotation shaft 76. A claw portion 76N is integrally formed adjacent to the O-ring OL at the upper end of the inclined rotation shaft 76. A locking claw 78N of the post sleeve 78 of the massage head 24 is detachably engaged with the locking claw 76N. Note that the post sleeves of the other four types of massage heads (needle massage head) 32, (facial massage head) 34, (head massage head) 36, and (magnetic facial massage head) 38, as shown in FIG. 6, also have similar locking claws, so that the massage heads 32, 34, 36, and 38 can also be detachably attached to the connecting mechanism including the inclined rotation shaft 76 of the spur gears 70G1, 70G2, 70G3, and 70G4.

[0028] The lower end of a conductive gear shaft 74 supported by the upper housing 68A is fitted into the fitting portion on the inner side of the rotary shaft connecting portion of the spur gear 70G4. The upper end of the gear shaft 74 is connected to a conductive fixing screw 80 that is electrically connected to the output terminal of the control board 60. As a result, when a weak current is output from the output terminal of the control board 60 as described below, the weak current (voltage) supplied from the output terminal of the control board 60 is supplied to each of the massage heads 24, 32, 34, 36, and 38 shown in FIG. 6 via the fixing screw 80 and the gear shaft 74. Note that while two fixing screws 80 are shown in FIG. 8, the remaining two fixing screws 80 are not shown. That is, a total of four fixing screws 80 are provided corresponding to the massage heads.

[0029] As shown in Figure 10, the lower surface of the lower housing 68B has an opening 68b through which the inclined rotation shafts 76 of the spur gears 70G1, 70G2, 70G3, and 70G4 protrude. One end of a boot BO (not shown) that covers each inclined rotation shaft 76 and the connecting portion of each massage head 24 is fixed to the periphery of the opening 68b. A red LED board 72 is provided in the center of the lower surface of the lower housing 68B. The red LED board 72 is electrically connected to the control board 60. As a result, when the red LEDs of the red LED board 72 are lit, infrared light is irradiated to the outside (the scalp) through the cosmetic cover 26.

[0030] As shown in FIGS. 6, 8, and 10, the massage head (iontophoresis / ion derivation massage head) 24 includes a conductive silicone rubber main body including a plurality of comb-shaped contact pins 24ai (i = 1 to n, n is a positive integer) that contact the scalp, contact pins 24bi (i = 1 to n, n is a positive integer) arranged inside the contact pins 24ai, and a post sleeve 78 with a locking claw 78N. The conductive silicone rubber contact pins 24ai each have a spherical tip and are integrally formed with the main body at a predetermined interval along the circumference of the main body. The conductive silicone rubber contact pins 24bi are thinner than the contact pins 24ai and are arranged inside the arrangement of the contact pins 24ai at intervals narrower than the intervals between the contact pins 24ai, and are integrally formed with the main body at the circumference. Magnet 25 is made of, for example, terahertz ore (artificial ore) with a purity of 6N. When magnet 25 is in contact with the scalp and maintained at a predetermined temperature, it emits terahertz waves as electromagnetic waves. Terahertz waves are electromagnetic waves that have the effect of activating the movement of water molecules in the cells of the human body.

[0031] The massage head (needle massage head) 32, massage head (facial massage head) 34, and massage head (head massage head) 36 shown in Figure 6 are also made of, for example, conductive silicone rubber. The surface of the massage head (needle massage head) 32 has a conductive soft rubber tape on its surface, allowing for close contact with the scalp surface through the hair layer. The surface of the massage head (facial massage head) 34 is harder than the massage head (needle massage head) 32 and has a tapered conductive soft rubber tip, making it suitable for relatively insensitive skin. The surface of the massage head (head massage head) 36 has a short conductive soft rubber tape, making it suitable for scalps with short hairstyles. The spherical surface of the massage head (magnetic facial massage head) 38 is made of terahertz mineral and is suitable for use on body surfaces with little hair, using the iontophoresis control / ion extraction control described below.

[0032] The lithium battery 64 of the head massager 10 can be charged by a charger 28 shown in FIGS. 5A and 5B and the control board 60. As shown in FIG. 4, the charger 28 includes an annular mounting portion 28U on which the base plate 14 of the head massager 10 is placed, and a disk-shaped base portion 28D connected to the mounting portion 28U via a connecting portion. As shown in FIGS. 5A and 5B, the connecting portion connects a portion of the mounting portion 28U to a portion of the base portion 28D so that they are parallel to each other with a predetermined gap between them. The mounting portion 28U is provided with a pair of male connection terminals 28P1 and 28P2 that connect to the pair of female connection terminals 14a and 14b of the base plate 14. A receptacle 30 to which a Type-C USB connector plug for power supply is connected is provided on the outer periphery of the base portion 28D.

[0033] In addition, as shown in FIG. 1, the head massager 10 described above includes a control unit 100 on the control board 60. As shown in FIG.

[0034] 1, a command signal CD1 representing an ON / OFF command is supplied from a power button 16a in the operation unit 16, and an EMS mode request signal CM1, an ion introduction mode request signal CM2, and an ion derivation mode request signal CM3 are supplied from a mode switching button 16b to the control unit 100. In addition, when the plug of a Type-C power supply USB connector 106 connected to a predetermined power source is connected to a receptacle 30 of the filler 28, a detection signal Sv representing a voltage based on negotiation (specific communication between the power supply side and the power receiving side before power supply) is supplied to the control unit 100.

[0035] The control unit 100 includes a memory section 100M that stores program data for controlling the rotation of the drive motor 66 (described later), program data for controlling electrical muscle stimulation (EMS) (hereinafter also referred to as EMS), program data for controlling ion introduction, program data for controlling ion derivation, program data for controlling the lighting of light-emitting diodes (hereinafter also referred to as LEDs), program data for controlling the charging of the lithium battery 64, and the like.

[0036] The control unit 100 supplies a control signal CR to the motor drive / rotation control unit 108 to operate the drive motor 66 at a predetermined rotation speed based on a command signal CD1 from the power button 16a, which indicates an ON state. The motor drive / rotation control unit 108 then supplies a drive signal to the drive motor 66 to drive the drive motor 66 based on the control signal CR and rotate the drive motor 66 at the predetermined rotation speed. Therefore, when the massage head 24, the massage head (needle massage head) 32, the massage head (facial massage head) 34, the massage head (head massage head) 36, and the massage head (magnetic facial massage head) 38 are attached to the head massager 10, each massage head is rotated at a predetermined rotation speed. The rotation speed control may be configured to control the rotation speed at three speeds: low, medium, and high (85, 115, and 145 rotations per minute).

[0037] Furthermore, the control unit 100 operates the light-emitting diode (LED) board 72 based on a command signal CD1 representing an ON state command from the power button 16a, thereby causing the light-emitting diode (LED) board 72 to irradiate infrared rays toward the outside (scalp) through the cosmetic cover 26. This promotes blood circulation and basal metabolism in the scalp.

[0038] The control unit 100 determines whether the lithium battery 64 can be charged using a predetermined protocol based on the detection signal Sv indicating the voltage, and then supplies a control signal CB to the charging control unit 116 to start power supply. Based on the control signal CB, the charging control unit 116 then supplies a command signal to the charging circuit unit 126 to instruct the charger 28 to charge. Accordingly, charging of the lithium battery 64 begins. At this time, the control unit 100 supplies a control signal CL to the LED lighting control unit 114 to cause the battery remaining capacity / charged state display unit 16B to illuminate to indicate that charging is in progress. Based on the control signal CL, the LED lighting control unit 114 controls the LED circuit unit 124 to cause the five LEDs of the battery remaining capacity / charged state display unit 16B in the LED / indicator unit 128 to illuminate in white.

[0039] LED / indicator unit 128 is configured to include five LEDs in battery remaining capacity / charged state display section 16B. The five LEDs light up in white as battery remaining capacity / charged state display section 16B, and light up in blue in five stages according to the intensity during electrical muscular stimulation (EMS) operation, which will be described later.

[0040] For example, during charging, when the remaining charge is 0-20%, five LEDs of the battery remaining charge / charge status display unit 16B flash white; when the remaining charge is 21-40%, only the leftmost LED lights up and the remaining four LEDs flash; when the remaining charge is 41-60%, the first and second LEDs from the leftmost side light up and the remaining three LEDs flash; when the remaining charge is 61-80%, the first to third LEDs from the leftmost side light up and the remaining two LEDs flash; when the remaining charge is 81-99%, the first to fourth LEDs from the leftmost side light up and the remaining one LED flashes; when charging is completed, all five LEDs are lit. Note that when the remaining charge falls below 15% during operation of the head massager 10, only the leftmost LED lights up at a relatively high speed.

[0041] For example, when the head massage heads 36 are attached to the head massager 10, when an EMS mode request signal CM1 is supplied to the control unit 100 from the mode switching button 16b, the control unit 100 supplies a control signal CE to the EMS control unit 110 so that the four head massage heads 36 perform electrical muscle stimulation (EMS) operations on the scalp based on the EMS mode request signal CM1. Based on the control signal CE, the EMS control unit 110 supplies a weak current (voltage) to the gear shaft 74 and the multiple contact pins of the head massage heads 36 so that the EMS circuit unit 120 applies a positive potential to the multiple contact pins of one pair of head massage heads 36 of the four head massage heads 36 via the two fixing screws 80, and applies a negative potential to the multiple contact pins of the other pair of head massage heads 36 via the two fixing screws 80. This provides an electrical stimulus to the scalp. This stimulates the pores of the scalp, thereby suppressing hair loss. When massage head (needle massage head) 32, massage head (facial massage head) 34, and massage head (magnetic facial massage head) 38 are attached to head massager 10, and an EMS mode request signal CM1 is supplied to control unit 100 from mode switching button 16b, control unit 100 similarly supplies control signal CE to EMS control unit 110 so that the four massage heads 32, 34, and 38 perform electrical muscle stimulation (EMS) operation on the scalp based on the EMS mode request signal CM1. The intensity of the electrical muscle stimulation (EMS) operation on the scalp may be controlled, for example, in five levels. When the intensity of the electrical muscle stimulation (EMS) operation is controlled in five levels, the frequency is the same for all ranges, and the intensity of the electrical muscle stimulation (EMS) operation is controlled by adjusting the voltage in control board 60.

[0042] At this time, control unit 100 supplies a control signal CL to LED lighting control unit 114. Based on the control signal CL, LED lighting control unit 114 controls LED circuit unit 124 to cause five LEDs of LED / indicator unit 128 to light up in blue in five levels according to the intensity. When mode switching button 16b is operated once, the intensity increases and the number of lit blue LEDs increases by one.

[0043] Furthermore, for example, when four massage heads (iontophoresis / ion derivation massage heads) 24 are attached to the head massager 10 as shown in Figures 2(A) and 3(A), when the portion of the bottom shell 12 from the reduced diameter portion to the expanded diameter portion is held in the palm of the user's hand as described above and the band-shaped first conductive member 18 and the band-shaped second conductive member 20 are respectively placed in contact with each finger, the control unit 100 supplies a command signal CI to the iontophoresis / ion derivation control unit 112 to control iontophoresis based on the iontophoresis mode request signal CM2 from the mode switching button 16b. Based on the command signal CI, the ion introduction / ion derivation control unit 112 causes the ion introduction / ion derivation circuit unit 122 to apply a negative potential to the tips of the contact pins 24ai and 24bi made of conductive silicone rubber of the four massage heads 24 that are in contact with the scalp, and to supply a weak current (voltage) to the fixing screw 80, the gear shaft 74, and the multiple contact pins 24ai and 24bi of the head massage heads 24 in order to apply a positive potential to the above-mentioned band-shaped first conductive member 18 and band-shaped second conductive member 20.

[0044] Furthermore, when four massage heads (ion introduction / ion derivation massage heads) 24 are attached to the head massager 10, as described above, when the portion of the bottom shell 12 from the reduced diameter portion to the expanded diameter portion is held in the palm of the user's hand and the band-shaped first conductive member 18 and the band-shaped second conductive member 20 are respectively placed in contact with each finger, the control unit 100 supplies a command signal CD to the ion introduction / ion derivation control unit 112 to perform ion derivation control based on the ion derivation mode request signal CM3 from the mode switching button 16b. Based on the command signal CD, the ion introduction / ion derivation control unit 112 causes the ion introduction / ion derivation circuit unit 122 to apply a positive potential to the tips of the contact pins 24ai and 24bi made of conductive silicone rubber of the four massage heads 24 that are in contact with the scalp, and to supply a weak current (voltage) to the fixing screw 80, the gear shaft 74, and the multiple contact pins 24ai and 24bi of the head massage heads 24 in order to apply a negative potential to the above-mentioned band-shaped first conductive member 18 and band-shaped second conductive member 20.

[0045] As described above, when head massager 10 performs iontophoresis, magnet 25 in massage head (iontophoresis / ion derivation massage head) 24, when in contact with the scalp and maintained at a predetermined temperature, emits terahertz waves as electromagnetic waves, activating the movement of water molecules in the cells of the human body, thereby achieving the effect of, for example, making it easier for nutrients (hair growth agents) contained in shampoo used to wash the scalp to be absorbed. On the other hand, when head massager 10 performs ion derivation, magnet 25 in massage head (iontophoresis / ion derivation massage head) 24, when in contact with the scalp and maintained at a predetermined temperature, emits terahertz waves as electromagnetic waves, activating the movement of water molecules in the cells of the human body, thereby easily attracting and drawing in negatively ionized (negatively charged) substances in the epidermis (pores) of the human body to the positively ionized (positively charged) tips of contact pins 24ai and 24bi made of conductive silicone rubber in four massage heads 24. At the same time, dirt from pores and other areas that cannot be removed by shampoo is also removed.

[0046] Therefore, the massage head (iontophoresis / ion derivation massage head) 24 can reliably exert its iontophoresis and ion derivation effects even on the scalp of the head covered with hair.

[0047] Furthermore, even when the above-mentioned massage head (facial massage head with magnet) 38 is attached to the head massager 10, the ion introduction and ion extraction functions of the massage head (facial massage head with magnet) 38 can be reliably exerted, just as in the case of the massage head (ion introduction / ion extraction massage head) 24.
