In this manner, hair is removed by sandwiching and pulling the body hair between the rollers.

[Problems to be solved by the invention]

By the way, when pulling out the hair, the skin is also pulled as the hair is pulled, so you may feel the pain caused by the skin being pulled or pull out the hair just by pulling the skin with the hair There were things that I couldn't do. The present invention has been made in view of such a point, and an object of the present invention is to provide a hair removal device that can reduce pain when pulling and pulling body hair.

[Means for Solving the Problems]

Thus, the present invention is a hair removal device provided with hair removal means for pulling out hairs driven by a power unit and skin growth means, wherein the skin growth means has a ring shape surrounding the hair removal means and has a shaft. It is driven to rotate around, and has a feature that it has a skin stretching part that stretches the skin outward from the hair removal means located inside the ring-shaped skin stretching means in contact with the skin. I have.

[Action]

According to the present invention, the ring-shaped skin stretching means surrounding the hair removal means is driven to rotate, and the skin stretching part in the skin stretching means is directed outward from the hair removal means located inside the ring-shaped skin stretching means. By stretching the skin, the skin stretching means stretches the skin at the time of hair removal, so that the skin is not pulled together with the hair, and therefore, the pain at the time of removing the hair can be reduced.

【Example】

Hereinafter, the present invention will be described in detail with reference to an embodiment shown in the drawings. This epilating apparatus includes three types of rollers 1, 2, and 3. The roller 1 is fixed to an output shaft 50 of a motor 5 disposed inside the main body 4, and the roller 3 is a ring-shaped rotatably supported by a cylindrical holder 40 provided on the main body 4. The roller 2 is arranged concentrically with the roller 1, and the roller 2 is a shaft protruding from the motor mount 41.
The roller 42 is rotatably and slidably mounted in the axial direction so as to contact the outer peripheral surface of the roller 1 and the inner peripheral surface of the roller 3. Here, the roller 1 has a reverse taper whose tip is thicker, the roller 3 also has a reverse taper whose tip inner diameter is smaller, and the roller 2 has a taper whose tip is thinner. The roller 2 which is urged in the axial direction by the outer peripheral surface of the roller
In particular, the tapered surface reliably contacts the outer peripheral surface of the roller 1 and the inner peripheral surface of the roller 3 with a required pressure. Incidentally, a plurality of rollers 2 are arranged around the roller 1 at equal intervals. That is, the roller 1 is configured as a sun roller, the roller 2 is configured as a planetary roller, and the roller 3 is configured as a planetary system in which the roller is an internal roller. Roller 3
Is engaged with the holder 40 by the flange 30 provided on the outer peripheral surface thereof.
It does not deviate from 40. Further, the leading end surface of the roller 1 and the leading end surface of the roller 2 are smooth convex curved surfaces, respectively. Further, the leading end surfaces of the rollers 1, 2, and 3 are located at positions recessed from the leading end surface of the holder 40. ing. In FIG. 1, 46 is a switch, 47 is a battery, and 48 is a battery cover. The hair removal apparatus performs hair removal by rotating the rollers 1, 2, and 3 while pressing the rollers 1, 2, and 3 against the skin in the axial direction. If the roller 1 is driven to rotate, the roller 2 supported by the shaft 43 rotates around the shaft 43 by contact with the roller 1, and the roller 3 contacting the roller 2 with the inner peripheral surface thereof. Rotates with the rotation of the roller 2, and as shown in FIG. 3, the body hair 7 sandwiched between the roller 1 and the roller 2 and between the roller 2 and the roller 3 It is pulled and pulled out with the rotation of. At this time, the curvature of the inner peripheral surface of the roller 3 is small,
Is formed of an elastic body, so that the length of the contact portion between the roller 2 and the roller 3 in the circumferential direction is long, and therefore, the distance between the roller 2 and the roller 3 is large. The pinched body hair 7 is surely pulled out even if it is long. Further, even if the body hair 7 is lying, it is raised by the rollers 1 and 3 having the reverse tapered surface and is sent to the roller contact portion, so that reliable hair removal can be performed also at this point. The hair removal device is provided with a skin-stretching means. As shown in FIG. 2, the skin-stretching means includes a roller provided with a skin-stretching portion 33 as a convex portion or a concave portion on an end face. 3 is formed. The skin extending portion 33 provided on the roller 3 that rotates around the axis by the drive of the motor 5 is a convex portion or a concave portion that is inclined with respect to the rotation traveling direction. It surely stretches the skin where the hair that is nipped and pulled out grows, thus relieving the pain during hair removal. As shown in FIG. 4, gears 11 and 21 that mesh with each other may be provided on the outer peripheral surfaces of the rollers 1 and 2, and an internal gear 31 that meshes with the gear 21 may be provided on the inner peripheral surface of the roller 3. The rotation of each of the rollers 1, 2, and 3 is ensured without slippage. Further, as shown in FIG. 5, a shaft 42 supporting each of the plurality of rollers 2 is provided so as to protrude from a rotating plate 44 rotatable around an output shaft 50 of the motor 5, and The gear 22 provided on the second gear 2 may mesh with an internal gear 45 provided on the inner peripheral surface of the holder 40. In this case, while the roller 2 rotates and revolves, the roller 3 which also serves as a skin stretching means also rotates, and with the revolution of the roller 2, the contact position between the roller 1, the roller 2 and the roller 3,
That is, since the position where the body hair is pulled out is changed, the hair can be removed quickly. In addition, although the epilation method is exemplified by a planetary method, as shown in FIG. 6, the roller 1 fixed to the output shaft 50 of the motor 5, the ring-shaped roller 3 rotatably supported, and the like. May be shifted so that the outer peripheral surface of the roller 1 directly contacts the inner peripheral surface of the roller 3. FIGS. 7 and 8 show a state in which the lever 6 is slidably attached to the holder 40, one end protrudes from the end face of the holder 40, and the other end is provided with the lever 6 facing the auxiliary switch 49. The auxiliary switch 49 connected to is turned on when the lever 6 is retracted by pressing the front end surface of the holder 40 against the skin. That is, the motor 5 is not energized so that the distal end surface of the holder 40 is not pressed against the skin. If the waste hair is long and the hair is pulled before the rollers 1,2,3 come into contact with the skin, the skin will be pulled and the pain will increase, but this will not happen That is why.

【The invention's effect】

As described above, in the present invention, the hair removal device includes a hair removal device and a hair growth device for pulling out the hair driven by the power device, and the skin growth device is formed in a ring shape surrounding the hair removal device around its axis. It is driven to rotate, and is provided with a skin stretching portion that stretches the skin outward from the hair removing means located inside the ring-shaped skin stretching means in contact with the skin, so that the skin of the portion from which hair is pulled out is provided. Since the hair is removed while being stretched by the skin stretching means, the skin is not pulled together with the hair, thereby reducing pain when the hair is removed. Further, the skin stretching means is a ring-shaped roller, and the hair removing means is composed of the ring-shaped roller and a planetary roller which is in contact with the inner peripheral surface of the roller and also in contact with a sun roller arranged at the center of the ring-shaped roller. Therefore, the length of the circumferential contact portion between the ring-shaped roller and the planetary roller can be increased without increasing the overall size, and the small but long body hair can be reliably pulled out. In addition, since the ring-shaped roller also serves as a skin stretching means, the number of parts can be reduced and the size can be reduced. Furthermore, if the skin-stretching portion of the skin-stretching means is a convex portion or a concave portion inclined with respect to the rotational direction of the ring-shaped skin-stretching device, the skin can be effectively stretched.
