FIG. 4 is a diagram showing the arrangement of the electrodes 161 provided on the housing 10 of the beauty device 1. As shown in FIG. As shown in FIG. 4 , the housing 10 is provided with a grip 101 and a contact portion 102 .

The grip 101 is provided in a region near the end of the housing 10 in the +x direction, and is a part to be gripped by the user. The thickness and shape of the grip 101 are determined based on, for example, the average hand size of a typical user. Grip 101 may include a non-slip.

The contact portion 102 is located on the -z direction side of the surface of the housing 10, and is provided with four electrodes 161 and a vibration plate 171. As shown in FIG. The contact portion 102 is provided at a portion that does not overlap with the grip 101 .

The four electrodes 161 and diaphragm 171 shown in FIG. 4 are arranged side by side in the longitudinal direction (x-axis direction) of the housing 10 . As shown in FIG. 4, the electrodes 161a and 161b are adjacent to each other with a distance of x1. Moreover, the electrode 161c and the electrode 161d are adjacent to each other, and the distance therebetween is x3. On the other hand, the electrodes 161b and 161c are separated by the diaphragm 171, and the distance is x2. The magnitude relationship between these distances is x2>x1 and x2>x3.

Therefore, for example, when the electrode 161a is set to the positive electrode and the electrode 161b is set to the negative electrode, and an electric signal is output to these electrodes, the parts of the human body that come in contact with them are separated by x1. Therefore, electrical stimulation is applied to the site of length x1.

On the other hand, for example, if the electrode 161a is set to the positive electrode and the electrode 161d is set to the negative electrode, and an electric signal is output to these electrodes, the parts of the human body that come into contact with them are separated by (x1+x2+x3). Therefore, in this case, electrical stimulation is applied to a site having a length of (x1+x2+x3), which is longer than x1. As described above, when the control unit 11 of the beauty device 1 selects one of the plurality of electrodes 161 as the positive electrode and the negative electrode, the range of the human body through which the current is passed is adjusted according to the combination of the selected electrodes 161. .

<Operation of beauty device>
FIG. 5 is a cross-sectional view of the housing 10 viewed from the arrow VV in FIG. Note that the cross-sectional view of FIG. 5 is only an outline, and the scale, aspect ratio, etc. thereof are not limited. When the housing 10 is cut along a plane perpendicular to the x-axis in the -x direction from the electrode 161a, the cross-sectional shape of the housing 10 is a triangle with rounded corners, as shown in FIG.

Then, as shown in FIG. 5, among the rounded corners (also referred to as convex portions) corresponding to the vertices of this triangle, electrodes 161a are provided on convex portions in the -z direction. The surface of the electrode 161a in the −z direction is a curved surface 1610a curved along the surface of the housing 10. FIG. In other words, the electrode 161a is provided on a convex portion in the -z direction on the surface of the housing 10, and has a curved surface 1610a curved along the shape of this convex portion.

The user grips the grip 101 shown in FIG. 4 to hold the beauty device 1, and presses the contact portion 102 against his/her own body (human body) in the direction of arrow D2 (-z direction) shown in FIG. 5(a). The direction of the arrow D2 is also the direction toward the deep part of the user's body (deep part direction). That is, the curved surface 1610a is a convex curved surface in the direction against which the electrode 161a is pressed.

The electrode 161b, the electrode 161c, the electrode 161d, and the diaphragm 171 are also provided on a convex portion in the -z direction on the surface of the housing 10, and have a convex curved surface similar to the curved surface 1610a in the pressing direction. respectively.

Then, the user presses the contact portion 102 in the arrow D2 direction and moves the cosmetic device 1 along, for example, the arrow D1 direction (+y direction) shown in FIG.

Since the user's body has soft subcutaneous tissue under the skin, when the electrode 161a is pressed in the direction of the arrow D2, the user's skin is bent to the curved surface 1610a of the electrode 161a according to the strength of the pressing force. Deform along the shape. The user's body contacts curved surface 1610a so as to wrap curved surface 1610a.

For example, when the user presses the electrode 161 with a predetermined force in the direction of the arrow D2, each curved surface of the electrode 161 (including the curved surface 1610a) is moved to the position L1 shown in FIG. Buried and touched. Therefore, at this time, the part of the curved surface 1610a that comes into contact with the user's body is the part indicated by the thick line in FIG. 5(a).

On the other hand, when the user presses the electrode 161 in the direction of arrow D2 with a force stronger than the force described above, each curved surface of the electrode 161 extends beyond L1 to the position L2 shown in FIG. It burrows into the user's body and touches it. The position of L2 is in the +z direction relative to the position of L1.

That is, the electrode 161a shown in FIG. 5B is pressed in the direction of the arrow D2 (-z direction) with a stronger force than the electrode 161a shown in FIG. be buried in Therefore, at this time, the part of the curved surface 1610a that comes into contact with the user's body is the part indicated by the thick line in FIG. 5(b). This "portion indicated by a thick line in FIG. 5(b)" is larger than the "portion indicated by a thick line in FIG. 5(a)" described above.

As described above, the beauty device 1 is provided on the surface of the housing 10 and has a plurality of electrodes 161 each having a convex curved surface in the pressing direction, so that the curved surface of the electrode 161 contacts the user's body. The size of the range varies depending on the strength of the force with which the electrode 161 is pressed against the user's body.

Therefore, in the beauty device 1 according to the present invention, since the portion of the electrode 161 in contact with the body has a convex curved surface in the pressing direction, by adjusting the pressing force, a comparatively wide portion can be treated. It is possible to stimulate even small parts by sticking to each other. Incidentally, the relatively wide region is the abdomen, thigh, etc., having muscles such as the transversus abdominis, the external oblique, the serratus anterior, and the gluteus maximus. In addition, the relatively small part is the face or the like having muscles such as the orbicularis oculi muscle and the buccal muscle.

In addition, since the plurality of electrodes 161 are arranged side by side in the longitudinal direction of the housing 10 in the beauty device 1 according to the present invention, the control unit 11 selects one of the plurality of electrodes 161 as the positive electrode and the negative electrode. You can adjust the range of the electric current flowing through your body depending on whether you do it or not.

Further, in the beauty device 1 according to the present invention, the plurality of electrodes 161 and the vibration plate 171 are provided on the surface of the housing 10 and each have a convex curved surface in the pressing direction. By sliding it along the contacting skin while pressing it against the body, it is possible to apply electric stimulation and vibration while massaging the tissue under the skin in contact with the curved surface.

In addition, since the cosmetic device 1 according to the present invention has the rod-shaped housing 10, the contact portion 102 is brought into contact with a portion that is out of reach of the user, and the electrode 161 and the vibration plate 171 provide electrical stimulation and vibration. can give.
