Description

  The present invention relates to a hair removal device used for removing body hair for cosmetic purposes.

  2. Description of the Related Art Conventionally, a hair removal apparatus is known in which a frame covering a rotating cylinder provided with a hair removal claw for extracting hair is swingable with respect to a main body casing (see, for example, Patent Document 1).

  However, in the conventional example shown in the above-mentioned Patent Document 1, the frame covering the rotating cylinder swings and the followability to the skin is improved, but the hair is pulled out by the rotating cylinder when the frame swings. There is a problem that changes. In other words, the action of pulling out the hair with the rotating cylinder is to improve the hair removal efficiency by the hair removal claw grasping the root of the hair and continuously removing the hair, but conventionally, the rotating cylinder itself does not move widely, Since the frame moves when the hair removal head is moved along the skin and the hair removal is performed, the orientation of the frame relative to the skin changes, and accordingly the position where the hair of the rotating cylinder is pinched. Changes, the irritation is very large and painful, not only hurting the skin, but also the position where the hair is pinched is likely to be away from the skin surface, so the hair removal nail There is a problem that not only the hair removal operation cannot be performed by grasping the root of the hair, and the hair removal efficiency is deteriorated, but also the usability is poor.

  As another conventional example, there is known one in which rollers disposed before and after the rotating cylinder are allowed to move freely with the rotating cylinder (see, for example, Patent Document 2).

However, in the conventional example shown in the above-mentioned Patent Document 2, the rollers arranged before and after the rotating cylinder are allowed to swing together with the rotating cylinder. However, the rollers are arranged before and after one rotating cylinder to form a plane. For this reason, for example, it is difficult to pull out hairs in narrow places such as under the armpit, and there is a problem that usability deteriorates.

The opening / closing means 5a and 36 can be swung integrally with the hair removal block 2, and the comb 10 is arranged in the gaps between the plurality of rotating cylinders 4 .

With this configuration, when the hair removal block 2 is moved and pulled out, the hair removal block 2 composed of a plurality of rotating cylinders 4 swings around one swing fulcrum 3 and the hair removal claw. Since the opening / closing means 5a and 36 swing together with the hair removal block 2, a plurality of hairs can be efficiently pulled out by the plurality of rotating cylinders 4, and the entire hair removal block 2 swings according to the unevenness of the skin. However, since the hair removal position by the plurality of rotating cylinders 4 does not change, the skin is not damaged by irritating, and the hair holding position is close to the skin surface 6, and the hair removal is performed. The nail | claw 5a, 36 can carry out the operation | movement which removes hair continuously by grasping the root of hair, and it can reduce hair loss stimulus and there is no leftover, and hair removal efficiency is greatly compared with the past. It is Mel possible. In addition, since the hair can be removed while directly looking at the rotating cylinder 4, the targeted hair can be easily removed, the hair removal process can be performed quickly and easily, and the usability can be improved.
In addition, since the comb 10 is arranged in the gap between the plurality of rotating cylinders 4, the comb 10 hits the skin so that the sliding of the rotating cylinder 4 with respect to the skin is improved, and smooth hair removal without damaging the skin is possible. It becomes.

  Further, it is preferable that the fulcrum fulcrum 3 of the epilation block 2 is disposed at an intermediate position between the plurality of rotary cylinders 4 and the epilation block 2 is oscillated around an axis parallel to the axial direction of the rotary cylinder 4. In this case, since there is no variation in the distance from the swing fulcrum 3 to the plurality of rotating cylinders 4, the balance per skin of each rotating cylinder 4, 4 is improved when the hair removal block 2 is swinging, and the hair removal efficiency is further increased. it can.

  In addition, the epilation block 2 is provided with two rotating cylinders 4 and preferably provided with driving means for rotating the two rotating cylinders 4 in the same direction. Efficient hair removal can be performed with an arm or the like.

  Further, it is preferable that the comb 10 is formed in a comb shape. In this case, the comb 10 cuts the hair, and long hair and sleeping hair can be generated, so that the hair is guided to the rotating cylinder 4. The hair can be easily pulled and the hair introduction efficiency into the hair removal nails 5a, 36 can be increased, and at the same time, the hair can be reliably pulled out from the root by the hair removal nails 5a, 36. Hair removal can be performed.

  Further, it is preferable to provide a spring member for urging the hair removal block 2 toward a predetermined position in the swing direction A. In this case, the hair removal block 2 is spring-forced when the rotary cylinder 4 is separated from the skin. Automatically returns to a predetermined position, so that the direction of the epilation block 2 is always constant when pressed against the skin, so that the adhesion to the skin can be improved, and the epilation block 2 is in a free state at the predetermined position. There is no backlash due to the spring bias, and the structure can always be stopped at the same position, which improves usability.

  The spring member is preferably a coil spring 11 or a torsion coil spring 12.

  Further, it is preferable to connect a part of the gear train 8f (9f) of the gear train constituting the driving means coaxially with the swinging fulcrum 3 of the hair removal block 2, and in this case, regardless of the swinging of the hair removal block 2. The distance between the gears of the gear train of the drive means can be kept constant, so that stable performance of the drive means can be obtained, and generation of noise and vibration between the gears can be prevented.

  The hair removal head 1H is preferably detachable from the main body casing. In this case, the cleaning performance is improved and the exchange of the rotating cylinder 4 is facilitated.

It does not change due to unevenness of the skin, and the hair removal efficiency is greatly enhanced and the hair removal can be performed while directly looking at the rotating cylinder, so that the usability is improved without deteriorating the hair removal efficiency. Moreover, since the comb is arrange | positioned in the clearance gap between several rotation cylinders, when the comb hits skin, sliding with respect to the skin of a rotation cylinder improves, and the smooth hair removal without damaging skin becomes possible.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  The epilation device is formed in a size that can be grasped by a hand and has two rotations as shown in FIGS. 2 and 3 on a body casing (not shown) containing a motor as a driving source. A hair removal head 1H including a hair removal block 2 comprising a cylinder 4 and a drive means for rotationally driving them is provided.

  The hair removal head 1H is provided with hair removal claws 5a and 36 that are driven to open and close, and a hair removal block 2 that is integrally provided with two cylindrical rotating cylinders 4 for pulling out the hair sandwiched between the hair removal claws 5a and 36, and a main body. It is comprised with the side attachment part 7. FIG. The two rotating cylinders 4 have the same structure. As shown in FIG. 10, the rotating cylinder 4 includes a fulcrum plate 33, a plurality of (four in this embodiment) movable claws 5 a, and a pair of fixed claws 36 (in the embodiment, bent into a U-shape). 2 pairs) and a fulcrum stop member 34 and the like are provided. The fulcrum stop member 34 is provided with a hole 34d in the longitudinal direction, and the fulcrum stop member 34 and the movable claw 5a are prevented from coming off by a shaft 41 inserted through the fulcrum stop member 34 and the movable claw 5a.

  The opening / closing lever 39 constituting the opening / closing means of the hair removal claws 5a, 36 is slidably inserted in the axial direction of the rotating shaft 56j from eight holes provided on both ends of the rotating shaft 56j of the rotating cylinder 4, respectively. . The open / close lever 39 is always urged by a leaf spring (not shown). A protruding piece 5 c provided on the movable claw 5 a is fitted into the opening / closing lever 39. The opening / closing lever 39 opens and closes the hair removal claws 5a, 36 in the vicinity of the surface on the skin surface 6 side parallel to the plane connecting the respective rotation centers of the rotating cylinder 4, and the opening / closing lever 39 is described later in the present invention. It can swing together with the epilation block 2.

  On the other hand, a roller-type cam 29 is rotatably attached to the portion receiving the rotation shaft 56j for the rotating cylinder 4 by a shaft 29j. When the rotating cylinder 4 rotates, the cam 29 is moved in the axial direction of the rotating cylinder 4 by sequentially pressing the other ends of the plurality of opening / closing levers 39 arranged in the circumferential direction of the rotating cylinder 4 to move the movable claw 5a. Is moved to close the hair removal claw (movable claw 5a, fixed claw 36). When the movable claw 5a is opened and closed by rotating the rotary cylinder 4 about its axis, the hair held by the movable claw 5a and the fixed claw 36 is pulled out as the rotary cylinder 4 rotates.

  The structure in which the rotating cylinder 4 is broken into two is known from Japanese Patent Application No. 2002-87087, and the detailed description thereof is omitted.

1 to 4 show the basic configuration of the present invention. As shown in FIG. 1 to FIG. 4, a rotation cylinder 4 is provided which is driven to rotate by a driving means and pulls out hairs by opening and closing the hair removal claws 5a and 36, and at least the rotation cylinder 4 is arranged so that the rotation axis 56j is parallel. One epilation block 2 is configured by arranging two or more in parallel. The hair removal block 2 is provided with one swinging fulcrum 3, and the hair removal block 2 is held so as to be able to swing around the swinging fulcrum 3. In this example, the fulcrum fulcrum 3 of the epilation block 2 is disposed at an intermediate position between the two rotary cylinders 4 and has a structure in which the two rotary cylinders 4 and 4 are oscillated so as to always come into close contact with the skin. .

  In the present invention, the rotation of the rotary cylinder 4 is performed by the rotation of a motor (not shown) in the main body casing. That is, the rotational motion generated by the motor is transmitted to the gear portions 41g respectively provided in the two rotary cylinders 4 through the gear trains 8a to 8g constituting the driving means shown in FIG. At this time, the gear 8f coaxially connected to the swinging fulcrum 3 is inserted between the gear portion 41g of the one rotating cylinder 4 and the gear portion 41g of the other rotating cylinder 4, so that the two rotating cylinders 4 and 4 are rotated in the same direction via a gear 8f.

  Further, the hair removal head 1H is configured such that a hook 92a provided at the lower end of the main body side attachment portion 7 shown in FIG. 3 is inserted into a square hole of a pair of left and right slide frames attached to the main body casing (not shown). It is supposed to be fixed. Then, the main body side attaching portion 7 can be detached from the main body casing by operating the pair of left and right slide frames. This detachable structure is known from Japanese Patent Application No. 2002-87087 and the like, and detailed description thereof is omitted here.

  Moreover, in this example, the lower end surface of the epilation block 2 is a convex curved surface 13 that is curved in an arc shape toward the main body side attaching portion 7 side, and the upper end surface of the main body side attaching portion 7 is a concave curved surface into which the convex curved surface 13 is fitted. 14, the fulcrum fulcrum 3 of the epilation block 22 is pivotally supported with respect to the pair of left and right holding pieces 60 of the main body side mounting portion 7 with the convex curved surface 13 and the concave curved surface 14 slidably butted. Thus, the epilation block 2 is held slidably in the direction indicated by the arrow A in FIG. 1A with respect to the main body side mounting portion 7 with the swaying fulcrum 3 as the center. Furthermore, a spring member for biasing the epilation block 2 toward a predetermined position (the center position in the present embodiment) in the swinging direction A is provided on the opposing surface of the convex curved surface 13 and the concave curved surface 14. . Here, the spring member is composed of a coil spring 11, two spring support convex portions 16 and 17 are provided in the center of the concave curved surface 14 on the main body side attachment portion 7 side so as to face the swing direction A, and both ends of the coil spring 11 are provided. Are supported by spring supporting convex portions 16 and 17. Further, a stopper recess 15 which is long in the swing direction A is provided at the center of the convex curved surface 13 of the epilation block 2, and both ends of the stopper recess 15 are stopper surfaces 15a and 15b. The epilation block 2 is in a state in which one spring supporting convex portion 16 in FIG. 1 (b) hits one stopper surface 15b from the state of FIG. 1 (a) (or the other spring supporting convex portion 17 is in the other state. It is possible to move farther until it hits the stopper surface 15a. At this time, the spring force is always applied to the hair removal block 2 in a direction returning to a free state at a predetermined position (FIG. 1A) by the compressive force of the coil spring 11.

  Thus, when the epilation block 2 is pressed against the skin while the two rotating cylinders 4 are rotated, the epilation block 2 can oscillate around one fulcrum fulcrum 3 according to the unevenness of the skin, and the epilation block 2 The opening / closing means of the hair removal claws 5a, 36 is also moved along with the movement. Accordingly, a large number of hairs can be efficiently pulled out by the two rotating cylinders 4 and the hair removal position by the plurality of rotating cylinders 4 does not change even if the entire hair removal block 2 swings according to the unevenness of the skin. Therefore, not only does it cause less irritation and damage to the skin, but also the position where the hair is pinched is close to the skin surface 6, so that the hair removal nails 5a and 36 grasp the root of the hair and continuously remove the hair. In particular, it becomes easy to pinch and pull out short hairs, and it is possible to reduce hair loss stimulation and to reduce unremoved parts. In addition, since hair removal can be performed while directly looking at the plurality of rotating cylinders 4, the hair removal efficiency is not deteriorated, and it is also easy to pull out hairs in narrow places such as under the armpits, which improves usability. Furthermore, since each of the plurality of rotating cylinders 4 can be driven by one motor, the entire epilation device can be reduced in size and cost.

  Further, in this example, the swaying fulcrum 3 of the epilation block 2 is arranged at an intermediate position between the plurality of rotating cylinders 4 and oscillates about an axis parallel to the axial direction of the rotating cylinders 4. Since the distance to the two rotary cylinders 4 and 4 becomes equal, the balance per skin of each rotary cylinder 4 is improved when the epilation block 2 is swung, and the epilation efficiency can be further increased.

  Moreover, since the epilation block 2 is spring-biased to a predetermined position in the swinging direction A by the coil spring 11, when the rotary cylinder 4 is separated from the skin, the epilation block 2 automatically returns to the predetermined position by the spring force. Since the direction of the epilation block 2 when pressed against the skin is always constant, the adhesion to the skin can be enhanced, and even when the epilation block 2 is in a free state at a predetermined position, There is no rattling and the structure is always stationary at the same position, so it is easier to use.

  Further, the gear 8f coaxially connected to the swing fulcrum 3 is inserted between the gear portion 41g of one rotating cylinder 4 and the gear portion 41g of the other rotating cylinder 4, and therefore the two rotating cylinders 4 , 4 rotate in the same direction via the gear 8f, so that efficient hair removal can be performed with legs and arms having the same hair growth direction.

  In this example, a comb 10 that swings integrally with the epilation block 2 is disposed in the gap between the two rotating cylinders 4 and 4. Here, a comb 10 is provided so as to swing along with the epilation block 2. When the comb 10 hits the skin, the sliding of the rotating cylinder 4 with respect to the skin is improved, and smooth hair removal without damaging the skin becomes possible. Further, it is desirable to form the comb 10 in a comb shape. As a result, the comb 10 presses the base of the hair in the skin and squeezes out the hair, so that a hair-stabilizing effect is obtained, and the sleeping hair or the hair is surely raised and the hair is introduced into the hair removal nails 5a and 36. The efficiency can be increased, and at the same time, the hair can be pulled out by the hair removal claws 5a and 36 reliably from the root, and the hair removal can be performed efficiently while reducing the hair removal stimulation. As a result, there is an advantage that the skin touch is good, the skin is always pulled and there is little irritation, and the follow-up to the skin becomes very good without being influenced by the usage or part of the person.

  Further, since a part of the gears 8f of the gear trains 8a to 8g constituting the driving means are connected coaxially with the swinging fulcrum 3 of the hair removal block 2, the gear trains 8a to 8g are connected regardless of the swinging of the hair removal block 2. The distance between the gears of 8 g can be kept constant, so that a stable drive transmission performance of the drive means can be obtained, and the generation of noise and vibration between the gears 8 a to 8 g can be prevented.

  Further, since the hook 92a of the hair removal head 1H can be attached to and detached from the main body casing (not shown), the hair removal head 1H can be replaced according to the application, and the cleaning performance is improved, and the rotating cylinder is improved. 4 can be easily replaced.

5 to 9 show an embodiment of the present invention. The configuration for holding the epilation block 2 slidably is the same as the basic configuration shown in FIGS. 1 to 4, and corresponding portions are denoted by the same reference numerals. In this example, the swing fulcrum 3 of the epilation block 2 is arranged closer to the lower side than the center between the rotating cylinders 4 and 4. A torsion coil spring 12 is used as a spring member that biases the epilation block 2 in the swinging direction A. In this example, a recess 18 for accommodating the torsion coil spring 12 is provided at the center of the concave curved surface 14 on the main body side mounting portion 7 side, and two opposite to the swing direction A at the center of the convex curved surface 13 of the epilation block 2. Spring retainers 20 and 21 are provided. Then, the epilation block 2 can swing from the state shown in FIG. 5A to a state where it contacts one spring press 21 shown in FIG. 5B (or a state where it contacts the other spring press 20). At this time, since the torsion coil spring 12 applies a spring force that always returns the hair removal block 2 to the free state (FIG. 5A), the skin of the rotating cylinder 4 is the same as when the coil spring 11 is used. In addition to improving the adhesion to the hair, there is no backlash due to the biasing of the spring even when the epilation block 2 is in a free state, so that the structure can always remain at the same position. Furthermore, in this example, as shown in FIGS. 8 and 9, drive means for rotating the two rotary cylinders 4 in the opposite directions is provided. Here, the gear 9f connected coaxially with the swing fulcrum 3 is engaged with only the gear portion 41g of one rotating cylinder 4, and the gear portion 41g of one rotating cylinder 4 and the gear of the other rotating cylinder 4 are engaged. The portion 41g meshes with each other. As a result, the two rotating cylinders 4 and 4 are rotated in opposite directions, and there is an advantage that efficient hair removal can be performed on the side where the hair grows apart.

  In the above embodiment, the epilation block 2 in which the two rotating cylinders 4 and 4 are integrated has been described. However, the number of the rotating cylinders 4 may be three or more.
