With reference to FIG. 1, the structure of the components of the cosmetic roller in one embodiment of the present invention will be described. The cosmetic roller in one embodiment includes a lower grip 1, a grip sealing material 2, an upper grip 3, a window 4, a window sealing material 5, a cosmetic cover 6, and two rotating rollers. A shaft 7, two caps 8, two nuts 9, two resin washers 10, two nuts 11, springs 12, three wires 13, and two rotating bodies 14. , two bearing members 15 , an LED 16 , three screws 17 and a solar cell panel 18 .

The outer periphery of the lower grip 1 has a U-shaped groove 1a formed in a part of the outer periphery of the bifurcated portion 1c in the upper part of FIG. A vertically long groove 1a is provided on the outer periphery. The bifurcated portion 1c of the lower grip 1 is provided with two holes 1b through which the rotating shaft passes. The lower grip 1 is provided with three holes 1d, 1e and 1f for screwing. The surface of the lower grip 1 is plated with metal except for the hole 1c. Therefore, the surface of the lower grip 1 is conductive, but only the hole 1c portion is non-conductive.

The rotating shaft 7 is inserted into the hole 1c, and the wiring 13 is connected to the base end portion 7c of the rotating shaft 7. However, since the surface of the hole 1b is not plated with metal, the rotating shaft 7 and the lower side of the hole 1b are not metal-plated. The grip 1 and the upper grip 3 are insulated. The insides of the lower grip 1 and the upper grip 3 are resin moldings.

The sealing material 2 has a shape that matches the upper and lower grooves 1a as a whole, and a longitudinally divided cylindrical seal that is shaped along the arc of the forked portion 1c in a portion corresponding to the forked portion 1c where the groove 1a does not exist. It has a part 2a.

The upper grip 3 has projections 3a, 3a, 3a having shapes corresponding to the grooves 1a. The upper grip 3 has a forked portion 3c curved to correspond to the forked portion 1c. The upper grip 3 has three holes 3d, 3e and 3f corresponding to the three holes 1d, 1e and 1f.

The window portion 4 has a groove 4a on its outer edge. A window seal 5 is placed in the groove 4a.

The decorative cover 6 has a window 6a.

The rotary shaft 7 has a flange portion 7a, a distal end portion 7b, and a proximal end portion 7c. The most proximal portion of the proximal end portion 7c has a structure in which the wiring 13 can be easily connected. A cap 8 is inserted into the distal end portion 7b, and has a D-shaped cross section so that the cap 8 does not idle. The hole formed in the cap 8 also has a D-shaped cross section accordingly. The proximal end portion 7c is inserted into the hole 1b of the bifurcated portion 1c, and has a D-shaped cross section so as not to idle. The hole 1b also has a D-shaped cross section accordingly.

The washer 10 is inserted on the proximal end portion 7c side, but is not limited thereto.

As is the case with the wiring of FIG. 3B, a conductive spring 12 is arranged around the hole 1e of the lower grip 1. As shown in FIG. Wires are attached to the springs 12 through which electrical conductivity with the lower grip 1 and the upper grip 3 is achieved.

The rotating body 14 penetrates through the inside. The bearing member 15 has a structure through which the rotating shaft 7 is passed. The bearing member 15 is press-fitted inside the rotor 14 . The rotating shaft 7 and the bearing member 15 are made of metal and have electrical conductivity. The inside of the rotating body 14 is a resin molded product, and the surface thereof is plated with metal. Therefore, the rotating shaft 7, the bearing member 15, and the rotating body 14 are energized.

The LED 16 is attached to the hole 3g.

(manufacturing process and structure)
The manufacturing process and structure of the cosmetic roller according to an embodiment of the present invention will be described below with reference to FIGS. 2 to 10. FIG.

As shown in FIG. 2, the sealing material 2 is put into the groove 1a of the lower grip 1. As shown in FIG. Also, the rotating shaft 7 is inserted into the hole 1b. Although not shown in FIG. 2, in the case of the wiring of FIG. 3, wiring to the lower grip 1 through the solar cell panel 18 and the spring 12, and wiring to the LED 16 and the rotating shafts 7, 7 are performed. A solar panel 18 is mounted on a platform provided on the lower grip 1 .

Various wiring methods are conceivable, and one example is shown in FIGS. 3A and 3B. In the wiring example shown in FIG. 3A, one terminal of the LED 16 is electrically connected to the rotating shaft 7, and the other terminal is electrically connected to the negative (or positive) pole of the solar cell panel 18. In FIG. Then, the other rotating shaft 7 is electrically connected to the positive (or negative) pole of the solar cell panel 18 . As described above, since the rotation shaft 7, the bearing member 15, and the rotor 14 are energized, the wiring shown in FIG. current flows through the skin through the two rotating bodies 14 . At that time, since electricity is supplied through the skin, the LED 16 is illuminated. This allows the user to confirm that a weak current is flowing through the skin when the LED 16 is illuminated. The current that flows depends on the size of the solar cell and the brightness of the surroundings, but is not limited to several μA to several tens of μA (the same applies hereinafter).

In the wiring example shown in FIG. 3B, one terminal of the LED 16 is electrically connected to the two rotating shafts 7, and the other terminal is electrically connected to the negative electrode (or positive electrode) of the solar panel 18. do. Then, the lower grip 1 is electrically connected to the positive (or negative) pole of the solar panel 18 . In the example described above, electrical connection to the lower grip 1 and the upper grip 3 was realized by wiring with the spring 12, but it is also possible to directly connect the wiring to the lower grip or the upper grip 3. Needless to say. When the user grips the beauty roller with bare hands and at least one of the rotating bodies 14 contacts the skin, the skin of the gripped hand and the skin with which the rotating bodies 14 are in contact are energized. As a result, the LED 16 lights up, so that the user can confirm that a weak current is flowing through the skin.

As shown in FIG. 4 , the upper grip 3 is placed on the lower grip 1 . The LED 16 is attached by being inserted from the inside of the hole 3g. The solar panel 18 is visible through the hole in the upper grip 3. A sealing material 5 is put in the window portion 4 .

As shown in FIG. 5 , the window 4 is attached to the hole of the upper grip 3 , and the upper grip 3 and the lower grip 1 are fixed with screws 17 .

As shown in FIG. 6, the cosmetic cover 6 is inserted into the upper grip 3 while bending. Light can be supplied to the solar cell panel 18 through the window 6a.

FIG. 7 shows the position of the bearing member 15. The bearing member 15 is press-fitted into the rotating body 14 and inserted into the rotary shaft 7 together with the rotating body 14, resulting in the state shown in FIG. Become.

As shown in FIG. 9, since the rotating body 14 penetrates, a nut 9 is attached to the tip portion 6b to prevent the rotating body 14 from slipping out of the rotating shaft.

Then, as shown in FIG. 10, a cap 8 is attached to the distal end portion 6b to close the through hole of the rotating body 14 so that the surface of the cap 8 and the rotating body 14 are flush with each other.

It should be noted that the brightness of the LED differs depending on the magnitude of the flowing current. If the skin is moist, the resistance will be small and the current flowing will be large, so the LED will shine brightly. On the other hand, if the skin is dry, the resistance will increase, the current will flow less, and the LED will glow dimly. This makes it possible to check the condition of the skin, whether it is moist or dry, based on the brightness of the LED.

In the above-described embodiment, the LED 16 lights up when the power is turned on, so that the user can know that the weak current is flowing through the skin. , the LED 16 is illuminated, and the LED 16 may be extinguished when a weak current flows. In that case, wiring is made so that a current always flows from the solar panel 18 to the LEDs 16, and when the skin is positioned between the two rotating bodies 14, the current does not flow to the LEDs 16 side. The circuit configuration may be such that current flows to the skin side. Such a short circuit to the skin side is obvious to those skilled in the art, and various well-known circuits can be adopted.

In this case, if the skin is dry, the resistance increases, and the current does not flow to the skin side, so the LED does not disappear, so if the LED does not disappear, the skin is dry. and users can understand.

Although the invention has been described in detail, the foregoing description is merely illustrative of the invention in all respects and is not intended to limit its scope. It goes without saying that various modifications and variations can be made without departing from the scope of the invention. Constituent elements of the invention disclosed in this specification shall be established as independent inventions. The present invention also includes a device in which each constituent element is combined by any combination method.
