Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair removal apparatus mainly used for removing body hair for cosmetic reasons.

[0002]

2. Description of the Related Art Several types of hair removal devices of this kind have been proposed so far, and Japanese Patent Publication No. 42-3535 discloses a pair of rollers whose axial end faces face the body surface. An apparatus that removes hair by holding and pulling body hair between both rollers so that the surfaces come into contact with each other is shown.

[0003]

However, in the above-mentioned publication, since the pair of rollers only rotate together, the appliance itself must be moved in order to pinch body hair between the two rollers. No. In addition, since the hair must be guided to a portion where the two rollers come into contact with each other, the efficiency of introducing the hair is low. In addition, increasing the speed of pulling out the hair reduces stimulation of hair removal.However, if the rotation speed of the roller is increased, the time during which the hair is pinched also becomes shorter, and the hair is moved between both rollers before the hair is pulled out. Often, it is painful just to pull out the hair and get out. In addition, since the speed at which the device is moved also has an effect on this point, it is extremely difficult to operate the device so that hair can be removed with a small amount of hair loss stimulation.

[0004] 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 capable of reliably removing body hair with a small amount of stimulation.

[0005]

According to the present invention, there is provided a hair removal device in which hair removal means is formed by a pair of rollers whose peripheral surfaces are in contact with each other, wherein the tip end in the axial direction is a contact surface with the body surface. It is characterized in that at least one of the pair of rollers performs rotation and revolution.

[0006] Since there is a roller that revolves in addition to the rotation, the pinching position of the body hair changes with the revolution, so that a wide range of hair removal can be performed without the need to move the instrument. Since it also revolves in addition to the rotation, the body hair can be quickly pulled out. The roller that rotates and revolves here can be configured as a planetary roller that contacts the inner peripheral surface of the ring-shaped roller and the outer peripheral surface of the sun roller disposed at the center of the ring-shaped roller.

In this case, a plurality of planetary rollers are provided, and each of the planetary rollers is rotatably supported around a shaft by a rotating plate which is rotatable coaxially with the sun roller, and comes into contact with the sun roller and the ring-shaped roller, respectively. It is preferred that In addition, the sun roller has an inverted tapered shape in which the tip side in the axial direction becomes thicker,
It is also preferable that the ring-shaped roller has a reverse tapered shape in which the inner diameter on the axial front end surface side is reduced, and the planetary roller has a tapered shape in which the axial front end side becomes thinner and is spring-biased toward the axial front end side. .

The pair of rollers may be provided with gears that mesh with each other.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on an example of an embodiment. The epilating apparatus shown in the illustrated example is provided with three kinds of rollers 1, 2, and 3. The roller 1 is fixed to an output shaft of a motor 5 disposed inside a main body 4 via a motor mount 41, and the roller 3 is
Is a ring-shaped member which is supported and fixed by a cylindrical holder 40 provided on the roller, is arranged concentrically with the roller 1, and the roller 2 is attached to the shaft 43 so as to be rotatable and axially slidable. The outer peripheral surface of the roller 1 and the inner peripheral surface of the roller 3 come into contact with each other.

Here, a plurality of rollers 2 are arranged at equal intervals around the roller 1, and a shaft 43 supporting each roller 2 is rotatable around the output shaft of the motor 5. From the rotating plate 44. Motor 5
When the roller 1 is rotated by the roller 1, the roller 2 that is in contact with the outer peripheral surface of the roller 1 and the inner peripheral surface of the ring-shaped roller 3 rotates and revolves. This is a planetary system in which 2 is a planetary roller and roller 3 is an internal roller.

Further, in the illustrated example, the roller 1 has an inverted taper whose tip becomes thicker, the roller 3 also has an inverse taper whose tip inner diameter becomes smaller, and the roller 2 has a taper whose tip becomes thinner. The roller 2, which is urged in the direction, has its outer peripheral surface, especially the tapered surface, with respect to the roller 1 and the roller 3, and the outer peripheral surface of the roller 1 and the roller 3
Contact with the required pressure at the inner peripheral surface of the. Even if the accuracy of the distance between the shafts is low, the contact pressure between the roller 1 and the roller 2 and between the roller 2 and the roller 3 can be reliably increased to the pressure required for pinching the body hair. Further, the leading end surface of the roller 1 and the leading end surface of the roller 2 are smooth convex curved surfaces, respectively, and the leading end surfaces of the rollers 1, 2, 3 are located at positions more concave than the leading end surface of the holder 40. . In FIG. 1, reference numeral 46 denotes a switch, 47 denotes a battery, and 48 denotes a battery cover.

However, this hair removing device is provided with the rollers 1,
The hair is removed by rotating the roller 1 with the motor 5 while the axial end faces of the rollers 2 and 3 are pressed against the skin. If the roller 1 is driven to rotate by the motor 5, the hair is supported by the shaft 43. Roller 2 is Roller 1
Not only does it rotate about the shaft 43 by contact with, but also contacts the inner peripheral surface of the roller 3, so that it also revolves around the roller 1 as shown in FIG. . Then, the body hairs 7 sandwiched between the rollers 1 and 2 and between the rollers 2 and 3 are pulled out with the rotation of the rollers 1 and 2.

At this time, as the roller 2 revolves, the roller 1
Since the contact position between the roller 2 and the roller 2 and the contact position between the roller 2 and the roller 3, that is, the position where the body hair 7 is sandwiched and pulled out, the body hair can be caught and pulled out without moving the device, and the rotation is also possible. In addition to this, the speed of revolving is added to increase the speed of pulling out the hair, and the change in the above-mentioned pulling-out position increases the distance to pull the pinched hair, ensuring that the hair is not irritated. The hair can be pulled out and hair can be removed quickly.

Further, since the inner peripheral surface of the roller 3 has a small curvature and the roller 2 is formed of an elastic material, the length of the contact portion between the roller 2 and the roller 3 in the circumferential direction becomes longer. Roller 2 and roller 3
The hair 7 caught between the hairs is surely pulled out even if it is long, and even if the hair 7 is sleeping, it is raised by the rollers 1 and 3 having the reverse tapered surfaces and fed into the roller contact portion. Therefore, also in this respect, reliable hair removal can be performed.

Gears that mesh with each other may be provided on the outer peripheral surfaces of the rollers 1 and 2, and an inner gear that meshes with the gear of the roller 2 may be provided on the inner peripheral surface of the roller 3. The rotation of the roller 2 is reliably performed without slipping. As shown in FIG. 3, the gear 22 provided with the roller 2 including the gear 21 meshing with the gear 11 of the roller 1 may be meshed with the internal gear 45 provided on the inner peripheral surface of the holder 40. In this case, since the roller 3 can also be rotated as indicated by the arrow in FIG. 4, the processing efficiency of hair removal can be further increased.

Here, the roller 2 for rotating and revolving is used.
Is a planetary system in which the inner peripheral surface of the ring-shaped roller 3 and the outer peripheral surface of the sun roller 1 are in contact with each other. The contact position between the paired rollers is changed by rotating and revolving. Whatever should be done is acceptable.

[0017]

As described above, in the present invention, at least one of the pair of rollers whose axial end surface is in contact with the body surface performs rotation and revolution. The pinching position of the body hair changes with the revolution, and it is possible to remove a wide range of body hair without the need to move equipment, and because it also revolves in addition to rotation, the pulling speed of body hair Therefore, the body hair can be removed with less stimulation and the hair removal efficiency is high.

The roller that performs the rotation and the revolution here is configured as a planetary roller that comes into contact with the inner peripheral surface of the ring-shaped roller and the outer peripheral surface of the sun roller disposed at the center of the ring-shaped roller. A roller for revolving can be easily obtained, and in particular, a plurality of planetary rollers are provided, and each planetary roller is rotatably supported around a shaft by a rotating plate coaxially rotatable with the sun roller. By bringing the hair into contact with the sun roller and the ring-shaped roller, respectively, it is possible to easily obtain a body that simultaneously pulls out the hair at a plurality of locations.

In the case of the planetary system, the sun roller has an inverted tapered shape in which the tip end in the axial direction is thicker, the ring-shaped roller has an inverted taper shape in which the inner diameter on the tip surface side in the axial direction is reduced, and the planetary roller has an axial tip end. If the side is tapered and the spring is biased toward the tip in the axial direction, the contact pressure between the rollers can be set not by the distance between the shafts but by the pressure of the spring for axial bias. Because it is possible to easily obtain the required contact pressure, and because the reverse tapered roller will cause sleeping hair,
Hair removal efficiency can be increased.

The pair of rollers may be provided with gears that mesh with each other. It is possible to obtain a movement in which the body hair can be pulled out without slippage.
