Description

Technical Field

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

Background Art

[0002] In an electric shaver, for example, as shown in Patent Document 1, there has been proposed an electric shaver provided with an ion introduction device in a head portion for efficiently transporting a cosmetic such as shaving cream from the outside to the inside of the body. In such an ion introduction device of an electric shaver, a shaving head that is moved on the skin to which the cosmetic is applied is provided with a plurality of adjacent electrodes constituting a star-shaped ion introduction device, and different potentials are applied to each electrode (see FIG. 6). Further, in an electric shaver for the skin, for example, as shown in Patent Document 2, instead of a heating means provided in the head portion, an action by electromyostimulation (EMS: Electrical Muscle Stimulation) that exhibits a tightening effect on the skin, an action by ion introduction that can moisturize the skin as described above, an action by ion extraction that exhibits an effect of removing dirt from pores of the skin, or a combination of these actions may be applied to an electric shaver for the skin.

[0003] Further, in a beauty electric brush device, for example, as shown in Patent Document 3, in order to efficiently perform both scalp care and facial care, there has been proposed a device in which an attachment for scalp care and an attachment for facial care can be selectively attached to a main body. The base of the attachment for scalp care and the base of the attachment for facial care are selectively attached to the main body by fitting the convex portion thereof with the groove of the base of the main body. At that time, when a weak voltage is applied to the interlocking shaft by connecting the interlocking shaft and the steel lid, a weak current flows through the interlocking shaft and the steel lid through the attachment for scalp care or the attachment for facial care that is rotated, and an electric stimulation is applied to the scalp or the face.

[0005] In scalp care using a beauty electric brush device, as shown in Patent Document 3, there is a demand for the use of an ion introduction device that efficiently transports nutrients contained in shampoo, etc., from the outside to the inside of the body, or an ion export device that has the effect of removing dirt from pores.

[0006] However, because the scalp is covered with hair, the ion introduction and ion export devices cannot directly contact the scalp, which may prevent the ion introduction and ion export effects from being reliably achieved.

[0007] Considering the above problems, the present invention aims to provide a head massager that can reliably exhibit ion introduction and ion extraction effects. [Means for solving the problem]

[0008] To achieve the above objectives, the head massager according to the present invention comprises: a housing having an operating section that houses a massage head drive mechanism, a drive motor for driving the massage head drive mechanism, a control unit electrically connected to the drive motor, and a secondary battery for supplying power to the drive motor and the control unit; a plurality of types of massage heads, including an ion introduction / ion export massage head that is detachably attached to the massage head drive mechanism via a coupling mechanism; a motor drive control unit connected to the control unit for driving and controlling the drive motor; an electrical muscle stimulation (EMS) control unit connected to the control unit for controlling the operation of an EMS circuit that supplies a predetermined potential to a plurality of contact pins made of conductive silicone rubber of the plurality of types of massage heads; and an ion introduction / ion export control unit connected to the control unit for controlling the operation of an ion introduction / ion export circuit that supplies a predetermined potential to a plurality of contact pins made of conductive silicone rubber of the ion introduction / ion export massage head, wherein the ion introduction / ion export massage head has at least a magnet made of terahertz ore that comes into contact with the skin.

[0009] The iontophoresis / iontophoresis massage head may have a magnet molded from terahertz mineral that contacts the scalp, located inside a plurality of contact pins made of conductive silicone rubber that are spaced apart along the circumference.

[0010] The massage head drive mechanism may consist of multiple gear trains. The secondary battery of the head massager may be charged via a capacitor on which the housing is mounted and electrically connected. The housing may have a red light-emitting diode (LED) substrate on its underside. The internal 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 export massage head has at least a magnet made of terahertz mineral that comes into contact with the skin,stomach It can reliably exhibit both ion introduction and ion extraction effects. [Brief explanation of the drawing]

[Figure 10] Figure 9 is a perspective view showing the bottom of the gearbox together with the massage head. [Modes for carrying out the invention]

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

[0014] In FIG. 2(A), the outer shell of the head massager 10 includes a resin upper shell 16 that forms the top part, a resin bottom shell 12 that is integrally formed by being continuously connected downward from the upper shell 16, and a resin disk-shaped base plate 14 that is joined to the lower end of the bottom shell 12 and supports a gear box 68 (see FIG. 7) described later. The upper end of the base plate 14 and the lower end of the bottom shell 12 are sealed and joined. Thereby, the internal space of the housing formed by the upper shell 16, the bottom shell 12, and the base plate 14 is made into a sealed space having a waterproof structure by a boot BO described later, so the head massager 10 can be used simultaneously even during hair washing or the like.

[0015] An operation part 16A having a power button 16a and a mode change button 16b is formed on the inclined surface of the upper shell 16. A battery remaining amount / power storage state display part 16B showing the power storage state of a lithium battery 64 (see FIG. 7) as a secondary battery described later is formed in a part that is continuous from the end of the inclined surface of the upper shell 16 to the reduced diameter part of the bottom shell 12. The battery remaining amount / power storage state display part 16B is formed, for example, by arranging five light emitting diodes (LEDs) in a row at a predetermined interval.

[0016] As shown in FIGS. 3(A) and 7, a strip-shaped first conductive member 18 is provided on the front portion of the end portion in the enlarged portion that extends radially from the central portion of the reduced-diameter portion of the bottom shell 12, facing the operation portion 16A of the upper shell 16. Also, a strip-shaped second conductive member 20 is provided at a position facing the strip-shaped first conductive member 18 on the back portion of the enlarged portion of the bottom shell 12. The length of the strip-shaped second conductive member 20 along the circumferential direction of the bottom shell 12 is set to be longer than that of the strip-shaped first conductive member 18. The strip-shaped first conductive member 18 and the strip-shaped second conductive member 20 are used as one electrode, and the same positive charge or negative charge is applied in the ion introduction control / ion导出 control described later. In the ion introduction control / ion导出 control described later, a positive charge or a negative charge different from the charges applied to the four massage heads (ion introduction / ion导出 massage heads) 24 and the four massage heads (face 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 from the reduced-diameter portion to the enlarged portion of the bottom shell 12 is easy to hold because it is grasped with the palm, and the strip-shaped first conductive member 18 and the strip-shaped second conductive member 20 are surely brought into contact with each finger. As a result, the strip-shaped first conductive member 18 and the strip-shaped second conductive member 20 are surely electrically connected to the body. On the other hand, when each finger is separated from the strip-shaped first conductive member 18 and the strip-shaped second conductive member 20, the strip-shaped first conductive member 18 and the strip-shaped second conductive member 20 are in a non-conductive state with the body, so the ion introduction control / ion导出 control is automatically stopped.

[0018] As shown in Figure 2(A), four massage heads (ion introduction / ion export massage heads) 24 (see Figure 6) are connected to each inclined rotating shaft portion 76 of the spur gears 70G1, 70G2, 70G3, and 70G4, which are supported by the lower housing 68B of the gearbox 68 within the base plate 14. These massage heads protrude downward through the opening 68b of the lower housing 68B (see Figure 10) and various openings (not shown) of the base plate 14. As shown in Figure 2(B), the connection portions of each massage head 24 and each inclined rotating shaft portion 76 are covered with boots BO, thereby sealing the openings of the base plate 14. In the center of the lower surface of the base plate 14, as shown in Figure 2(B), a decorative cover 26 is formed integrally with the lower surface of the base plate 14, facing a red light-emitting diode (LED) substrate 72 fixed to the gearbox 68, which will be described later. On the lower surface of the base plate 14, between two adjacent massage heads 24, and near the back of the bottom shell 12, a pair of female connectors 14a and 14b are provided, to which a pair of male connectors 28P1 and 28P2 of the charger 28 (described later) are connected, respectively.

[0019] Inside the bottom shell 12, there is a drive control component housing that contains a drive motor 66, a gearbox 68 which houses a spur gear train (see Figure 9) to which the output shaft of the drive motor 66 is connected, a control board 60 which drives and controls the drive motor 66, and a lithium battery 64 which serves as a secondary battery to supply power to the drive motor 66 and the control board 60.

[0020] Inside the upper shell 16, there is a compartment for housing operating components, which accommodates the head of the drive motor 66, the touch switch circuit board 64, and the like.

[0021] As shown in Figure 8, the control board 60, supported on the periphery of each fixing screw hole in the upper housing 68A of the gearbox 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 also has a connector 62C connected to the other end of a flexible circuit board 62, one end of which is connected to a touch switch board 65. A lithium battery 64, 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 strip-shaped first conductive member 18 and the strip-shaped second conductive member 20 are each electrically connected via lead wires to the output terminals of the control board 60 at the same potential.

[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 level / 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] The gearbox 68, as shown in Figures 8 and 9, comprises an upper housing 68A supporting the control board 60 and a lower housing 68B that is covered by the upper housing 68A. The lower housing 68B is supported on the inner circumference of the base plate 14, as shown in Figure 7. The upper housing 68A is fixed to the lower housing 68B by screwing each small screw BS through the through hole in the upper housing 68A into each female screw hole 68FS in the lower housing 68B (see Figure 8). As a result, multiple gear trains that transmit the rotational force of the drive motor 66 to the four massage heads 24 are arranged in the accommodating space formed between the upper housing 68A and the lower housing 68B.

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

[0026] Since the coupling mechanisms of the spur gears 70G1, 70G2, 70G3, and 70G4, including the inclined rotating shaft 76, have the same structure, the coupling mechanism of spur gear 70G4 will be described, and the descriptions of the coupling mechanisms of the other spur gears 70G1, 70G2, and 70G3 will be omitted.

[0027] The inclined rotating shaft 76 of the spur gear 70G4 is integrally formed with respect to the rotating shaft connecting portion of the spur gear 70G4 at a predetermined inclination angle. An O-ring OL is provided in the groove at the upper end of the inclined rotating shaft 76. At the upper end of the inclined rotating shaft 76, a claw portion 76N is integrally formed adjacent to the O-ring OL, to which the locking claw 78N of the post sleeve 78 of the massage head 24 is detachably locked. The post sleeves of the other four types of massage heads (needle massage head) 32, (face massage head) 34, (head massage head) 36, and (face massage head with magnet) 38, as shown in Figure 6, also have similar locking claws, so the massage heads 32, 34, 36, and 38 are also detachable from the connecting mechanism including the inclined rotating 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 inner mating portion of the rotating shaft coupling portion of the spur gear 70G4. The upper end of the gear shaft 74 is connected to a conductive fixing screw 80, which 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 will be described later, the weak current (voltage) supplied from the output terminal of the control board 60 is supplied to the massage heads 24, 32, 34, 36, and 38 shown in Figure 6 via the fixing screw 80 and the gear shaft 74. Note that although two fixing screws 80 are shown in Figure 8, the remaining two fixing screws 80 are not shown, meaning that 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 from which the inclined rotating shafts 76 of the spur gears 70G1, 70G2, 70G3, and 70G4 protrude. One end of a boot BO (not shown) that covers the connection between each inclined rotating shaft portion 76 and each massage head 24 is fixed to the periphery of the opening 68b. A red LED substrate 72 is provided in the center of the lower surface of the lower housing 68B. The red LED substrate 72 is electrically connected to the control board 60 described above. As a result, when the red LEDs on the red LED substrate 72 are lit, infrared light is emitted outwards (to the scalp) through the decorative cover 26.

[0030] The massage head (ion introduction / ion export massage head) 24, as shown in Figures 6, 8, and 10, comprises a main body made of conductive silicone rubber, which includes a plurality of comb-shaped contact pins 24ai (i=1 to n, n is a positive integer) that come into contact with 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 having locking claws 78N; and a hemispherical magnet 25 fixed to the center inside the contact pins 24bi of the main body and in contact with the scalp. Each contact pin 24ai made of conductive silicone rubber has a spherical tip and is formed integrally with the main body at predetermined intervals along the circumferential direction of the main body. The contact pins 24bi made of conductive silicone rubber are thinner than the contact pins 24ai and are arranged inside the arrangement of the contact pins 24ai at narrower intervals than the spacing between the contact pins 24ai, and are formed integrally with the main body at all times. Magnet 25 is formed, for example, from terahertz ore (artificial ore) with a purity of 6N. ru.

[0031] The massage heads (needle massage head) 32, (face massage head) 34, and (head massage head) 36 shown in Figure 6 are also made of conductive silicone rubber, for example. The surface of the massage head (needle massage head) 32 has a conductive soft rubber tape on its surface, so it adheres more closely to the scalp surface through the hair layer and makes better contact. The surface of the massage head (face massage head) 34 is harder than that of 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 face massage head) 38 is made of terahertz mineral, and is suitable for use on body surfaces with little hair in the ion introduction control / ion export control described later.

[0032] The lithium battery 64 of the head massager 10 is rechargeable by the charger 28 shown in Figures 5(A) and (B) and the control board 60 described above. As shown in Figure 4, the charger 28 is composed of an annular mounting portion 28U on which the base plate 14 of the head massager 10 is mounted, and a disc-shaped base portion 28D connected to the mounting portion 28U via a connecting portion. As shown in Figures 5(A) and (B), the connecting portion connects a part of the mounting portion 28U and a part of the base portion 28D so as to be parallel to each other at a predetermined interval. The mounting portion 28U is provided with a pair of male connectors 28P1 and 28P2 that are connected to a pair of female connectors 14a and 14b of the base plate 14. A receptacle 30 is provided on the outer circumference of the base portion 28D to which a plug for a Type-C USB connector for power supply is connected.

[0033] Furthermore, as shown in Figure 1, the head massager 10 described above includes a control unit 100 on the control board 60.

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

[0035] The control unit 100 includes a storage unit 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 extraction, 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 rotational speed based on the command signal CD1, which indicates an ON state command from the power button 16a. As a result, the motor drive / rotation control unit 108 drives the drive motor 66 based on the control signal CR and supplies a drive signal to the drive motor 66 to rotate it at a predetermined rotational speed. Therefore, when the massage head 24, the massage head (needle massage head) 32, the massage head (face massage head) 34, the massage head (head massage head) 36, and the massage head (face massage head with magnet) 38 are each attached to the head massager 10, each massage head is made to rotate at a predetermined rotational speed. Note that the rotational speed control may be configured to control the rotational speed in three stages: low speed, medium speed, and high speed (85, 115, and 145 revolutions per minute).

[0037] Furthermore, the control unit 100 operates the light-emitting diode (LED) board 72 based on the command signal CD1, which indicates an ON state command from the power button 16a, causing the LED board 72 to emit infrared rays toward the outside (scalp) via the decorative 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 according to a predetermined protocol based on a detection signal Sv representing voltage, and then supplies a control signal CB to the charge control unit 116 to start power supply. As a result, the charge control unit 116 supplies a command signal to the charge circuit unit 126 to cause the charger 28 to start charging based on the control signal CB. Thus, charging of the lithium battery 64 begins. At that time, the control unit 100 supplies a control signal CL to the LED lighting control unit 114 to cause the battery level / charge status display unit 16B to light up 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 level / charge status display unit 16B in the LED / indicator unit 128 to light up in white.

[0039] The LED / indicator unit 128 includes five LEDs in the battery level / charge status display unit 16B. These five LEDs illuminate in white as part of the battery level / charge status display unit 16B, and illuminate in blue in five stages according to the intensity during the electrical muscle stimulation (EMS) operation described later.

[0040] The battery level / charge status indicator 16B, for example, during charging, will have five LEDs flashing white when the charge level is 0-20%, the leftmost LED lit up and the remaining four LEDs flashing when the charge level is 21-40%, the first and second LEDs from the left lit up and the remaining three LEDs flashing when the charge level is 41-60%, the first and second LEDs from the left lit up and the remaining three LEDs flashing when the charge level is 61-80%, the first to third LEDs from the left lit up and the remaining two LEDs flashing when the charge level is 81-99%, the first to fourth LEDs from the left lit up and the remaining one LED flashing. After charging is complete, all five LEDs will light up. Additionally, during operation of the head massager 10, if the charge level falls below 15%, only the leftmost LED will light up relatively quickly.

[0041] For example, when the head massage heads 36 are attached to the head massager 10, and 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) 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 section 120 applies a positive potential to multiple contact pins on one pair of head massage heads 36 via two fixing screws 80, and a negative potential to multiple contact pins on the other pair of head massage heads 36 via two fixing screws 80. This delivers electrical stimulation to the scalp. As a result, hair loss is suppressed by stimulating the hair follicles on the scalp. When the massage head (needle massage head) 32, the massage head (face massage head) 34, and the massage head (face massage head with magnet) 38 are each attached to the head massager 10, and an EMS mode request signal CM1 from the mode switching button 16b is supplied to the control unit 100, the control unit 100 similarly supplies a control signal CE to the EMS control unit 110 so that the four massage heads 32, 34, and 38 perform electrical muscle stimulation (EMS) on the scalp based on the EMS mode request signal CM1. The intensity of the electrical muscle stimulation (EMS) on the scalp may be controlled in, for example, five levels of intensity. When the intensity of the electrical muscle stimulation (EMS) is controlled in five levels, the frequency is the same in all ranges, and the intensity of the electrical muscle stimulation (EMS) is controlled by adjusting the voltage on the control board 60.

[0042] At that time, the control unit 100 supplies a control signal CL to the LED lighting control unit 114. 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 LED / indicator unit 128 to light up blue in five stages according to their intensity. When the mode switching button 16b is pressed briefly once, the intensity increases, and one more blue LED lights up.

[0043] Furthermore, for example, as shown in Figures 2(A) and 3(A), when four massage heads (ion introduction / ion export 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 to the expanded diameter is grasped in the palm of the user's hand and the strip-shaped first conductive member 18 and the strip-shaped second conductive member 20 come into contact with each finger, the control unit 100 supplies a command signal CI to the ion introduction / ion export control unit 112 to perform ion introduction control based on the ion introduction mode request signal CM2 from the mode switching button 16b. Based on the command signal CI, the ion introduction / ion extraction control unit 112 supplies 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 head 24 in order to cause the ion introduction / ion extraction circuit unit 122 to perform the following actions: apply a negative potential to the tips of the conductive silicone rubber contact pins 24ai and 24bi of the four massage heads 24 that are in contact with the scalp, and apply a positive potential to the aforementioned strip-shaped first conductive member 18 and strip-shaped second conductive member 20.

[0044] Furthermore, when the four massage heads (ion introduction / ion export 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 to the expanded diameter is grasped in the palm of the user's hand and the strip-shaped first conductive member 18 and the strip-shaped second conductive member 20 come into contact with each finger, the control unit 100 supplies a command signal CD to the ion introduction / ion export control unit 112 to perform ion export control based on the ion export mode request signal CM3 from the mode switching button 16b. Based on the command signal CD, the ion introduction / ion extraction control unit 112 supplies 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 head 24 in order to cause the ion introduction / ion extraction circuit unit 122 to perform the following operations: apply a positive potential to the tips of the conductive silicone rubber contact pins 24ai and 24bi of the four massage heads 24 that are in contact with the scalp, and apply a negative potential to the aforementioned strip-shaped first conductive member 18 and strip-shaped second conductive member 20.

[0045] As described above, when the head massager 10 performs ion introduction, example For example, it has the effect of making the nutrients (hair growth agents) contained in shampoo used to wash the scalp more easily absorbed. On the other hand, when the head massager 10 performs ion export, people Negatively charged substances within the skin (pores) of the body are easily attracted to and sucked into the positively charged tips of the conductive silicone rubber contact pins 24ai and 24bi of the four massage heads 24. At the same time, dirt from pores and other areas that cannot be completely removed by shampooing is also removed.

[0046] Therefore, even on the scalp of the head, which is covered with hair, the ion introduction and ion export effects of the massage head (ion introduction / ion export massage head) 24 can be reliably exerted.

[0047] Furthermore, even when the aforementioned massage head (magnetic facial massage head) 38 is attached to the head massager 10, the ion introduction and ion export effects of the massage head (magnetic facial massage head) 38 can be reliably exerted, just as in the case of the massage head (ion introduction / ion export massage head) 24.
