  In the conventional beauty roller, there is not provided a configuration in which a rotating body is rolled on the skin surface and a high frequency current is applied from the rotating body to give a stimulus. Further, it is unknown what kind of stimulus is optimal for applying a high-frequency current together with a stimulus that makes contact with the rotating body while rotating.

  The present invention was created in view of the above-described problems of the prior art, and provides a beauty roller capable of applying an optimum high-frequency current in a beauty roller that rolls on the skin surface and performs beauty. With the goal.

In order to solve the above problems, the present invention provides the following beauty roller.
That is, in the beauty roller for performing cosmetics by applying a high-frequency current while rotating the abutment body against the skin surface, in the vicinity of the end portion, provided with a shaft support portion that supports the rotation axes of at least two rotation bodies, A substantially rod-shaped main body formed so as to be capable of gripping the outer circumference in the longitudinal direction, two rotating shafts of a rotating body protruding in a direction different from the longitudinal direction of the main body by a predetermined opening angle, and rotating by each rotating shaft A beauty roller comprising at least two rotating bodies that are free and have an electrode portion that applies a high-frequency current to at least a part of the skin surface, and a high-frequency generation means that energizes the electrode portion and generates a high-frequency current. provide.

  In the cosmetic roller, it is also possible to provide a configuration in which the high-frequency generating means is provided in the main body, and the shaft support is provided with conduction means for passing a high-frequency current from the main body to the rotating shaft.

The frequency of the high frequency current is particularly preferably 0.5 MHz to 5.0 MHz.
Moreover, it is particularly preferable that the output of the high-frequency current is 5 W to 35 W.

  The cosmetic roller may include rotation detection means for detecting the rotation of the rotating body, and the on / off of the high-frequency current may be controlled according to the detection result.

The present invention has the following effects by the above configuration.
That is, in a cosmetic roller that rotates with the rotating body in contact with the skin surface, in addition to stimulation by rotation of the rotating body, stimulation by application of high-frequency current can be combined to obtain a good feeling of use.
In particular, the effect can be most enhanced by setting the frequency of the high-frequency current within the range of 0.5 MHz to 5.0 MHz or setting the output within the range of 5 W to 35 W.

  When conducting a high-frequency current as in the present invention, it is necessary to consider an AC resistance or the like, but a conduction means for passing a high-frequency current from the main body portion to the rotating shaft is configured in the shaft support portion as in the present invention. Thus, the high frequency current generated in the main body can be applied to the rotating body.

  Furthermore, by providing the rotation detection means of the rotating body, for example, high-frequency current can be applied only during rotation, and it is possible to avoid applying high-frequency current locally on the skin surface.

Sectional drawing which shows the internal mechanism of a roller body. The transmission perspective view which shows the structure of the bearing member in a roller body, and a rotating shaft. The block diagram of the beauty roller which concerns on this invention.

Hereinafter, embodiments of the present invention will be described based on examples shown in the drawings. The embodiment is not limited to the following.
FIG. 1 is a perspective view of a beauty roller (1) according to the present invention. Near the end of the substantially rod-shaped main body (10), there are provided shaft support portions (11) and (12) for supporting the rotation shafts of the two roller bodies (20) and (21) which are rotating bodies. The user rolls the roller body (20) (21) while contacting the face, arms, legs, etc. while gripping the outer periphery of the main body (10).

  As shown in the figure, the roller bodies (20) and (21) are formed with bowl-shaped uneven surfaces (200) and (201) in parallel with the direction of the rotation axis, and this rolls on the skin surface. Thus, the warm feeling and tactile sensation of the metal material, the vibration caused by the uneven surfaces (200) and (201), the pressure when the roller bodies (20) and (21) abut, and the application of the high-frequency current according to the present invention By doing beauty.

  Ring-shaped first ring portions (202) and (212) are arranged on the outer circumference of the equator portion of the roller bodies (20) and (21), and ring-shaped second ring portions (203) and (213) are arranged on the outer circumference near one end. Each is provided. The high-frequency current according to the present invention can be applied to the skin surface from the first ring part (202) (212) or the second ring part (203) (213).

  In addition, in this invention, the shape of a rotary body is arbitrary and is not limited to a roller body (20) (21) as shown in a present Example. For example, it may be a sphere, an elliptical sphere having a major axis or a minor axis in the direction of the rotation axis, a substantially cylindrical meter, a substantially polygonal column, a substantially conical shape, a substantially polygonal pyramid, a drum shape, etc.

  Moreover, what is necessary is just to provide at least two rotary bodies, and it is also possible to provide two or more, for example, four at one end of the main body (10), or two at each end of the main body (10). . Further, the shape and size of the rotating body do not need to be the same, and may be one shape or two different shapes or sizes.

  The beauty roller (1) in the present embodiment includes a rechargeable battery inside the main body (10), and when placed on the charging stand (2) shown in FIG. 2, a charging terminal (not shown) of the main body (10). ) And a contact point (not shown) of the charging stand (2) are in contact with each other to charge the rechargeable battery. The charging stand (2) is further connected to a power adapter (not shown) or the like to supply power.

Next, the internal mechanism of the roller bodies (20) and (21) will be described with reference to FIGS. In addition, although it demonstrates using the roller body (20) of one side below, the other roller body (21) is also the same.
The outer shell constituting most of the outer peripheral surface of the roller body (20) is composed of a first outer shell portion (204), a second outer shell portion (205), and a third outer shell portion (206). The joint between the shell part (204) and the second outer shell part (205) is the second ring part (203), and the joint between the second outer shell part (205) and the third outer shell part (206) is the first ring part ( 202) are respectively fixed.

  On the base side of the roller body (20) formed as described above, there is a hole (206a) into which the rotary shaft (110) projecting from the shaft support portions (11) and (12) of the main body portion (10) is fitted. Is formed. A bearing member (130) as shown in FIG. 4 is inserted into the hole (206a). After the bearing member (130) is inserted, the tip end portion is screwed into the second ring portion (203) with a screw (131) to be fixed in the roller body (20).

  The inside of the bearing member (130) has a cylindrical shape, and the first bearing (132), bearing stopper (133), spacer (134), contact fixing member (135), and second bearing (136) are arranged in this order from the tip. ) Are inserted in order, and finally screwed with a sealing screw (137). Thereby, the roller body (20) is rotatable with respect to the rotating shaft (110) and does not separate from the rotating shaft.

  In this embodiment, the rotating shafts of the roller bodies (20) and (21) are eccentric. This configuration will be described. As shown in FIG. 3, the axial direction (L1) of the rotating shaft (110) is not arranged on the central axis of the roller body (20), but is inclined with respect to the axial direction (L2) of the central axis. Normally, by matching the central axis with the rotation axis, the outer periphery of the roller body (20) rotates at a fixed position during rotation. Also in the conventional beauty roller, the central axis and the rotation axis coincide with each other, and the skin surface is stimulated by the unevenness of the surface of the roller body.

  On the other hand, in the beauty roller according to the present embodiment, since the central axis and the rotation axis are inclined, when the roller is rolled on the skin surface, a twisting motion occurs in the roller body (20), and the two roller bodies (20) ( 21) The interval between intervals changes periodically, and the effect of picking up and stretching the skin is intermittently generated. This configuration contributes to ease of handling and weight reduction of the beauty roller because the roller body naturally vibrates irregularly with the rolling of the user without using a vibration device or a drive device.

  As described above, if the outer periphery of the roller body (20) is provided with the ridge-shaped uneven surfaces (200) (201) parallel to the rotation axis, the roller body (20) can be divided by the number of ridges during one rotation. Vibration can be applied to the skin surface, and one large twist can be applied during one rotation. Stimulation on the skin surface in the beauty roller is a very important function, and exhibits a characteristic behavior that cannot be realized with a general beauty roller. For example, since a large twist produces an effect of pulling up the skin, it is possible to enhance the massage effect on the skin and muscles where sagging is a concern.

In this embodiment, the axial direction of the rotating shaft and the central axis of the roller body are inclined. However, the central position in the cross section perpendicular to the axial direction of the rotating shaft and the position of the rotating shaft are at least partially. It can also be arranged eccentrically.
For example, a configuration in which the axial direction of the rotating shaft and the central axis are parallel and the position is eccentric may be employed.

In the present invention, in the beauty roller including at least two rotating bodies as described above, a high-frequency current is applied to the skin surface of the user from the electrode portion provided in the rotating body. FIG. 5 shows a block diagram of the beauty roller. Electricity is stored in the rechargeable battery (51) inside the main body (10) from the power supply unit (50) constituted by the above-described power adapter or the like. By supplying power from the rechargeable battery (51), a high frequency current is generated from a high frequency generation circuit (52) which is a high frequency generation means in the main body (10).
Of course, it is not essential to use the rechargeable battery (51) in the present invention, and power may be supplied directly from the external power supply section (50) to the high-frequency generation circuit (52). Moreover, a solar panel may be provided in the main body (10) and power may be supplied by solar power generation.

The high-frequency current is supplied from the high-frequency generation circuit (53) to the rotating shaft (110) through the shaft support portions (11) and (12). Needless to say, at least the contact portion of the shaft support portions (11) and (12) with the rotation shaft (110) and the rotation shaft (110) are formed of a conductive member.
And the contact member (140) fixed by the contact fixing member (135) of a bearing member (130) contact | abuts with the outer peripheral surface of a rotating shaft (110). The contact member (140) is a conductive leaf spring-like member, and the contact portion (140a) is pressed against the rotating shaft (110) by the elasticity of the spring, and the base end portion (140b) is a bearing member. Conducting with respect to (130). For this reason, even if it rotates relatively with a rotating shaft (110), it can supply with electricity to a bearing member (130) from a rotating shaft (110).

  Further, since the bearing member (130) is electrically connected to the second ring portion (203) fixed by the screw (131), a high frequency current can be applied from the second ring portion (203). Since the high-frequency current is passed between the one roller body (203) and the second ring portion (213) of the other roller body through the skin surface, it can act on the skin between the electrodes.

Regarding the conducting means of the present invention, the configuration of the contact member (140) as described above is optimal in consideration of the reactance in the high-frequency current, but a conductive bearing or a brush-like contact may be used.
Moreover, the structure which equips a roller body with a high frequency generation circuit (52) and supplies electric power from a main-body part (10) to a roller body (20) may be sufficient.

  The electrode part according to the present invention is not limited to the second ring part (203), but may be the first ring part (202) or the entire outer peripheral surface of the roller body (20). Moreover, not only the structure which supplies with electricity between roller bodies (20) (21) but the structure which supplies with electricity between a 1st ring part (202) and a 2nd ring part (203) may be sufficient. In addition, the arrangement location of the electrode part and the energization section are arbitrary.

(Another embodiment)
The beauty roller of the present invention may further include an energization control unit (53) and a rotation detection unit (54). In the present embodiment, the roller body (20) is provided with the rotation detector (54), and the main body (10) is provided with the energization controller (53).
The rotation detection unit (54) is configured by a known rotation sensor that detects a relative rotational movement between the bearing member (130) of the roller body (20) and the rotation shaft (110). As a detection method, any method such as a known electromagnetic type, magnet type, optical sensor, gyro, or the like can be used in addition to a method in which a minute generator is attached to the rotating shaft and detection is performed by the generated current.

When the rotation detection unit (54) detects rotation, the energization control unit (53) controls on / off of energization of the high-frequency current according to the detection result. The on / off of the output from the high frequency generation circuit may be controlled, or the power supply itself to the high frequency generation circuit may be turned on / off.
The energization control unit (53) may be provided inside the roller body (20), and the output from the electrode unit (140) may be controlled only when the rotation detection unit (54) detects rotation.
The main body (10) or the roller body (20) may be provided with a light emitting means so as to emit light only when a high frequency current is applied.

By using the rotation detector (54) as described above, a high-frequency current can be applied only when the roller bodies (20) (21) rotate. It is known that when a high-frequency current is applied to the skin surface, the energized part is heated, and excessively continuous energization may lead to discomfort. Therefore, in the present invention, it is possible to improve the usability by energizing only when the user rotates and uses the roller bodies (20) and (21).
This configuration is particularly effective in avoiding local energization because the contact area on the skin surface also changes when the roller body rotates.

  Instead of the rotation detecting means, the vibration of the main body (10) may be detected, and the high-frequency current may be applied only when the vibration is detected. For vibration detection, a known vibration sensor can be used. Also in this case, since the vibration accompanying the use is detected and energized, it is possible to avoid energizing continuously during the stop.

In the present invention, a favorable frequency and output were obtained by experiments for the high-frequency current applied from the beauty roller. An experimental example is shown below.
(Experimental example 1)
Using the cosmetic roller shown in the above embodiment, a high-frequency current having a frequency of 1.0 MHz, which is generally used in the past, was applied at each of the following outputs. Ten subjects performed sensory evaluations with an output of 2 W to 40 W, respectively, and scored inappropriate (0 points), appropriate (1 point), and optimal (2 points). The following table shows the results of counting the average points from 0 points to less than 1 point as Δ, 1 points to less than 1.5 points as ◯, and 1.5 points to less than 2 points as ◎.

According to the above experiment, it was evaluated that the effect was not sufficient when the output was 2 W, and the stimulus was too strong when the output was 40 W. Therefore, it was found that the output of the high frequency current applied in the cosmetic roller of the present invention is optimal from 10 W to 15 W, and the range of 5 W to 35 W is a good output range.
Therefore, in the present invention, it is preferable to set the output of the high-frequency current within the range of 5W to 35W.

(Experimental example 2)
Subsequently, a high-frequency current having an output of 10 W determined to be optimal in Experimental Example 1 was applied at each of the following frequencies using the cosmetic roller shown in the above example. Ten subjects performed sensory evaluation at frequencies of 0.1 MHz to 10.0 MHz, respectively, and scored inappropriate (0 points), appropriate (1 point), and optimal (2 points). The following table shows the results of counting the average points from 0 points to less than 1 point as Δ, 1 points to less than 1.5 points as ◯, and 1.5 points to less than 2 points as ◎.

According to the above experiment, it was evaluated that the effect was not sufficient when the frequency was 0.1 MHz, and that the effect was not sufficient when the frequency was also 10.0 MHz. Therefore, it was found that the optimum frequency of the high frequency current applied in the cosmetic roller of the present invention is 0.5 MHz to 3.0 MHz, and the range of 0.5 MHz to 5.0 MHz is a good frequency range.
Therefore, in the present invention, the frequency of the high-frequency current is preferably in the range of 0.5 MHz to 5.0 MHz.
