With such a configuration, the gap between the hair removing unit and the skin stretching unit or the vibrating unit can be reduced, and the width of the main body and the frame in the lateral direction can be reduced. Further, it is preferable to provide a cushioning member at the lower end portion of the output portion that is reciprocally driven in the vertical direction. With such a configuration, the shock noise generated during the reciprocating drive can be reduced by the cushioning member.

Further, it is preferable that the amount of amplitude or the frequency of the output section which is reciprocally driven in the vertical direction can be freely changed. With such a configuration, the amount of vibration or the frequency of vibration can be adjusted depending on the user or the site to be used, and the pain during hair loss can be reduced in the most preferable state. Further, it is preferable that the reciprocating driving means for reciprocally driving the output portion in the vertical direction is constituted by an elliptical gear. With such a configuration, the reciprocating drive becomes smooth, and the noise generated during the reciprocating drive can be reduced.

Further, it is preferable that a drive gear for driving the hair removing means and the skin stretching means or the vibrating means is formed with an unbalanced weight. With such a configuration, the vibration due to the rotation of the drive gear having an unbalanced weight, the vibration due to the swinging or rotation of the hair removing means, or the vibration generated during the reciprocating drive of the skin stretching means or the vibrating means are canceled each other. Therefore, the vertical vibration of the housing can be reduced.

Grooves 22b each having an arc centered on the shaft 25 are provided on the lower surface of the drive roller 30, and the drive rollers 30 of the pair of movable levers 27 are engaged with the groove 22b.

Further, as shown in FIG. 7, a large recess 20b is provided in front of the fixed claw 3a in the circumferential portion of the rotating body 20, and a roller rotatably attached to this recess 20b. Reference numeral 21 is press-fitted and fixed by a shaft 21a into a mounting hole 22c in the circumferential direction of a fixed claw 3a located at an end portion provided on the rotating body 20. At this time, the shaft 21a may be press-fitted and fixed to the roller 21, and the shaft 21a may be loosely inserted in the mounting hole 22c. As a result, the skin contact, which has been aggravated by the sliding stimulus of the ribs of the rotating body 20 during the rotation, rolls without pulling the skin by the roller 21 which is mounted so as to rotate, so that the skin contact is good, and even in the bone part. The impact of the fixed claw 3a and the movable claw 3b on the skin is softened by the roller 21, so that the contact with the skin is very good.

The driving means incorporated between the cam case 6 and the cam case cover 7 are as shown in FIG. 1, FIG. 2, FIG. 6, FIG.

It is configured to be rotatably attached, and when the motor 11 is rotated and the drive gear 32 is rotated,
Through the lever 26, the rotating body 20 reciprocally rotates about the shaft 25 within a predetermined angle. This rotation is performed between a state in which the roller 21 is located substantially in the center of the upper surface opening of the epilation unit case 39 and a state in which the movable claw 3b of the epilation claw 3 is in the same position. Simultaneously with the above rotation, the movable levers 27 reciprocate about the shaft 28 in opposite directions, and the pair of sliders 22, 22 in the epilation block 2 perform reciprocal linear movement in opposite directions. In addition, the movable claw 3b that reciprocally swings by the reciprocating motion of the sliders 22 and 22 has an operation in which two adjacent movable claws 3b simultaneously contact both surfaces of every other fixed claw 3a, and both sides of the remaining fixed claw 3a. The operation of simultaneously contacting two adjacent movable claws 3b is repeated. Since the fixed claws 3a at both ends are in contact with the movable claws 3a only on one side, the fixed claws 3a are made thicker and stronger than the other fixed claws 3a.

Here, in the present embodiment, the cam groove is formed so that the movable claw 3b makes one reciprocating motion during two reciprocating rotations about the shaft 25 of the epilation block 2. 9a is configured. That is, during one reciprocating rotation about the shaft 25 of the epilation block 2, the movable claw 3b moves from the state in which the movable claw 3b is in contact with the fixed claw 3a on the other side to the fixed claw 3 on the other side.
The state of contacting a is changed.

In this embodiment, as shown in FIGS. 11 and 12, the movable cam 27 is configured to reciprocate twice by one rotation of the rotary cam 9, so that the gear 3
The combination of the number of teeth of 2a and the face gear 9b is 1: 4, so that the rotation of the rotating body 20 and the grasping of the bristles can be always matched. Also, this movable claw 3b
Most of the above-mentioned transition is performed at the dead point when the movable claw 3b is located in the upper opening of the frame 5 among both dead points of the reciprocating rotation about the shaft 25 of the epilation block 2. At the same time, the movable claw 3b comes into contact with the fixed claw 3a at the transition at this time, and the movable claw 3b is slightly separated from the fixed claw 3a with which it is in contact at the other dead point. .

In other words, when the fixed claw 3a and the movable claw 3b come to a position facing the skin from the state where the roller 21 is in contact with the skin by one-way rotation about the shaft 25 of the epilation block 2, Hair is pinched by the fixed pawl 3a and the movable pawl 3b, and the hair removal block 2 is rotated in the reverse direction while the pinch is maintained, so that the hair is pulled out and the roller 21 is re-skinned again. When it comes into contact with, the operation of releasing the pinched hair is repeated.

As described above, in the hair removal cycle in this embodiment, the nail is opened to introduce the hair, the nail is then closed to grip the hair, and then the rotating body 20 is rotated to pull out the hair.
Then it is a regular cycle of opening the nails and releasing the hair. Therefore, in the present embodiment, hair loss stimulation (pain caused by hair loss) occurs due to regular hair removal.

Since it is connected to the long hole 42a by b, the pin 40a
The pin 40b slides in the long hole 42a with the connecting portion of and as a fulcrum, and the front skin extending portion 40 swings, whereby the comb-shaped front skin extending portion 40 pushes the skin and extends it forward. At the same time, by pushing the protrusion 43g upward,
The connecting arm 43 rotates about the shaft 5d as a fulcrum, and the long hole 43
The part a is pushed up. At this time, the skin stretching portion 41 after this is connected to the frame 5 by the pin 41a, and
Since the pin 41b is connected to the long hole 43a, the pin 41b is connected to the long hole 4a with the connecting portion of the pin 41a as a fulcrum.
Sliding in 3a, the later skin extending portion 41 swings, whereby the comb-shaped skin extending portion 41 pushes the skin and extends it backward. Thus, the vibrating body 35 moves upward, the front skin stretching section 40 swings forward to stretch the skin forward, and the back skin stretching section 41 swings backward to stretch the skin backward to remove hair. It is possible to surely and easily perform hair removal by the nails 3, and by extending the skin to remove hair, pain at the time of hair removal is reduced.

By the way, as described above, when the vibrating body 35 moves upward and the protrusions 42g and 43g are pushed upward and the front and rear skin stretching portions 40 and 41 swing to perform skin stretching, By the rotation of 42 and 43, the return spring portions 42f and 43f are strongly pressed against the case body 6A as shown in FIG. 14, and the return spring force is accumulated. Therefore, when the vibrating body 35 moves downward, the return springs 42f, 43 are arranged so as to follow the downward movement of the vibrating body 35.
The return spring force accumulated in f causes the connecting arm 42,
43 is rotated in the opposite direction to the state shown in FIGS. Thus, when the vibrating body 35 moves downward, the return spring force of the springs 42f and 43f causes the connecting arm 42,
43 rotates in the opposite direction, and a projection 42g is formed on the upper end of the vibrating body 35.
With the lower end surface of 43g still in contact, the protrusions 42g, 4g
3g moves downward. Therefore, when the vibrating body 35 moves upward again and pushes up the protrusions 42g and 43g upward, the vibrating body 35 does not collide with the protrusions 42g and 43g, and at the connection point of the vibrating body 35 and the protrusions 42g and 43g. It can stretch the skin without collision noise.

As described above, in the present embodiment, the skin extending portions 40 and 41 provided in the skin extending means swing to extend the skin from the initial position in the direction to extend the skin and return the skin extending position to the initial position. In this way, the movements of the skin extending portions 40 and 41 provided in the skin extending means are both in the direction of extending the skin from the initial position and from the skin extending position to the initial position. Since it is configured to perform a movement in the direction of returning to the position, the pain when the skin is pulled and the resistance when pulling out the hair is reduced, the pain at the hair loss is reduced, and the driving load is also reduced. It can be made smaller and does not involve hair.

Here, the comb 51, which is the front skin contact member, is surrounded by an elastic elastomer, and the comb-shaped protrusion 51a at the upper end of the comb 51 is formed of the elastic elastomer. The elastic elastomer is formed at the same time when the skin contact member 5 having the comb 51 is formed.
The hardness of the elastic elastomer is 50 ° to 80 ° so that the skin can be stretched and the hair can be conditioned while improving the contact with the skin. The comb 51 is guided on both sides by guide portions 5e provided on the frame 5 so as to be movable in the vertical direction, and a boss projecting from the back side of a handle 52 provided on the front surface of the frame 5 so as to be movable laterally. 52a is fitted in the cam groove portion 51b of the comb 51 that is movable in the vertical direction, and by moving the handle 52 in the horizontal direction, the comb 51 is moved in the vertical direction and the vertical position is selected to select the vertical direction. It can be fixed at the set position of. As a result, the amount of skin extension by the skin extension means can be adjusted by the comb 51 that constitutes the skin contact member. When the comb 51, which is the skin contact member, is moved upward, the amount of skin extension of the skin extension part is increased. Can be reduced to improve the skin contact with bones and the like.

The roller 54, which constitutes the skin contact member located at the rear, is formed of an elastic elastomer and is rotatably attached by a shaft 41a so that it can follow the skin and roll. Here, the hair removal unit is the main body 1

A hair removal unit case including a case body 6A provided with a stopper 8b and detachably locking the attachment locking portion 8b to the attachment locked portion 16d provided at the end of the holding hook 16. 39 is removably attached to the main body 1. In this case, the upper surface of the engaged portion 16d for attachment provided at the end of the holding hook 16 is an inclined surface. The lower end of the stopper 8b is also an inclined surface, and the laterally movable holding hook 16 is elastically biased by the spring member 19, so that the lower surface of the case body 6A ( That is, under the cam case base 8 Part) is pressed against the upper surface of the motor case 4, the inclined surface of the attachment locking portion 8b contacts the inclined surface of the upper surface of the attachment locked portion 16d, and the holding hook is resisted against the spring member 19. When 16 moves in the lateral direction, the attachment locking portion 8b is pushed downward and locked to the attachment locked portion 16d. When the hair removal unit is attached to the main body 1 in this manner, the gear 13a provided on the intermediate gear 13 meshes with the drive gear 32. When the hair removal unit is attached to the main body 1, both attachment / detachment buttons 17 are pressed to attach both holding hooks 16 to the spring member 1.
In this state, the pair of attachment locking portions 8b are positioned on both sides of the tunnel portion 4a in a state where the attachment locked portions 16d are retracted into the tunnel portion 4a by moving in the direction of approaching each other against 9 It is also possible to release the attachment / detachment button 17 so that the mounting locked portion 16d is locked to the mounting locking portion 8b.

On the other hand, in order to remove the hair removal unit case 39 containing the case body 6A, by pressing both attachment / detachment buttons 17, both holding hooks 16 are pushed in the direction in which they approach each other against the spring material 19. Since the mounting locked portion 16d is disengaged from the mounting locking portion 8b, it can be removed by pulling the hair removal unit case 39 upward in this state.

Next, another embodiment of the present invention will be described with reference to FIGS. Since the basic configuration of this embodiment is the same as the embodiment shown in FIGS. 1 to 18,
A description of the overlapping configuration will be omitted, and a configuration different from the above-described embodiment will be described below. An operation button 80 is attached to the front surface of the epilation unit case 39 so as to be vertically slidable. As shown in FIG. 20, the operation button 80 is provided with a hook 81 on the back side, and the hook 81 can be moved vertically to the back side of the edges on both sides of the hole 39d provided on the front surface of the epilation unit case 39. An operation button 80 is attached to the hair removal unit case 39 so as to be vertically movable by being locked. In addition to the hook 81, a boss 82 projects from the back surface of the operation button 80. The boss 82 is provided on the vibrating body 35 through the hole 39d of the epilation unit case 39 and the square hole 6f formed on the cam case 6. In addition, it is inserted in a long hole 35b that is long in the vertical direction.

That is, when the operation button 80 is at the lowermost end, the elongated hole 35b and the boss 82 are not buffered against the amplitude amount of the vibrating body 35.

Next, when the operation button 80 is in the middle position, the boss 82 regulates when the elongated hole 35b of the vibrating body 35 is lowered. That is, when the cam portion 9c rotates, the boss 82 inserted into the long hole 35b of the vibrating body 35.
Since the lower part is restricted by the vibrating roller 33 as shown in FIG. 23B, the vibrating roller 33 does not contact the low protrusion 91b, and as a result, the reciprocating drive amount of one rotation is reduced to half and the frequency is reduced. Is.

Further, when the operation button 80 is slid upward to the upper stage, the amplitude amount is reduced as shown in FIG. 23 (c), and in this case, the frequency is also halved. By moving the operation button 80 up and down to position it in the lower, middle, and upper stages as described above, the amount of amplitude changes and the frequency changes, as indicated by A, B, and C in FIG. Yes, when the pain felt at the time of hair loss is great, the operation button 80 is set to the lower stage to increase the frequency and the amount of amplitude, so that the pain at the time of hair loss can be eased, and when the pain is not felt so much, the operation is performed. By setting the button 80 to the middle stage or the upper stage, the number of vibrations and the amount of amplitude can be reduced and used. That is, it is possible to reduce the pain that differs depending on the site and the pain sensation due to individual differences as a whole.

By the way, when the operation button 80 is moved to the upper, middle, and lower stages, the operation button 80 is inserted into one of the upper and lower three-stage lock receiving portions 39e provided on both side edges of the hole 39d of the epilation unit case 39. The operation projection 80 can be held at any position in the upper, middle, and lower stages by the detachable locking of the locking projections 83 provided at both ends. Next, still another embodiment of the present invention will be described with reference to FIGS. 24 and 25.

The basic configuration of this embodiment is shown in FIGS.
Since the configuration is the same as that of the embodiment shown in FIG. 1, the description of the overlapping configuration will be omitted, and the configuration different from the above-described embodiment will be described below. In the present embodiment, the vibrating roller 33 rotatably provided on the vibrating body 35 is composed of an elliptical gear 33a. A gear 92 is formed on the outer peripheral portion of the upper surface of the rotary cam 9 so as to have an annular shape in plan view. The elliptical gear 33a meshes with the gear 92, and the rotating cam 9 rotates to rotate the elliptical gear 92, whereby the vibrating body 35 having the elliptical gear 33a rotatably attached reciprocates in the vertical direction. It moves. Here, the required amplitude amount D of the vibrating body 35 can be set by the elliptical shape of the elliptical gear 33a forming the vibrating roller 33 as shown in FIG.

Next, still another embodiment of the present invention will be described with reference to FIGS. Since the basic configuration of the present embodiment is the same as that of the embodiment shown in FIGS. 1 to 18, the description of the overlapping configuration will be omitted, and the configuration different from the above-described embodiment will be described below. In this embodiment, a recess 32c is provided eccentrically on the side of the drive gear 32 where the shaft 32b is attached. That is, in the present embodiment, the drive gear 32 has an eccentric weight. With this configuration, when the motor 11 is driven to rotate the drive gear 32 and the epilation block 2 is rotated by the link 26,
Since the epilation block 2 is in an unbalanced weight state due to the movable claw 3b, vibration is generated in the up-and-down direction, and in addition, reciprocating movement of the skin stretching means causes up-and-down vibration. It is possible to cancel the vibrations in the vertical direction, which eliminates the vibration transmitted to the hand through the housing 10, thus improving the usability.

In each of the above-described embodiments, an example has been described in which the hair removing device provided with the hair removing means for pulling hair out of the main body 1 which can be held by hand is provided with the skin extending means.
Instead of the skin stretching means, a vibrating means may be provided in the hair removing device so as to stimulate the skin by vibration so as to reduce pain during hair removal.
