At this time, the surgical elements 81a to 81d move the scalp in one direction according to the operation of the gears 41 to 46 and the arrangement relationship of the rotation base 55.

Here, the rotation operation of each of the surgical elements 81a to 81d provided in the scalp care device 10 will be described in detail mainly with reference to FIG. In addition, FIG. 9 shows a plan view when the scalp care device 10 is viewed from below. Incidentally, in FIG. 9, the direction orthogonal to the paper surface is the vertical direction. Moreover, the left-right direction in a figure is the left-right direction of the scalp care apparatus 10, and the up-down direction in a figure is a front-back direction.

The surgical elements 81a to 81d have a substantially square shape in plan view as shown in FIGS. Each of the treatment elements 81a to 81d is connected to the connection shaft 47 via the rotation base 55, the output shaft 56, and the treatment element base 71. The

surgical elements

81a and 81b adjacent in the front-rear direction rotate counterclockwise. The centers P1 and P2 of the treatment element base portion 82 of the

treatment elements

81a and 81b rotate around the output shafts 56 in a state where the phases are shifted from each other by 180 degrees. Similarly, in the

surgical elements

81c and 81d that rotate in the clockwise direction, the centers P3 and P4 of the surgical element base portion 82 of the

surgical elements

81c and 81d are out of phase with each other by 180 degrees. Rotate around. Further, the centers P1, P3 (centers P2, P4) of the treatment element base portions 82 of the

treatment elements

81a, 81c (the

treatment elements

81b, 81d) adjacent in the left-right direction are symmetrical with respect to the vertical bisector L. Rotate to

According to such a configuration, the centers P1 and P3 of the

surgical elements

81a and 81c and the centers P2 and P4 of the

surgical elements

81b and 81d are most distant from each other in the front-rear direction (by rotating 90 degrees in the reverse direction from FIG. 9). When each of the surgical elements 81a to 81d rotates 90 degrees from the above state, as shown in FIG. 9, the

surgical elements

81a and 81c are closest to each other in the left-right direction. At this time, pinching is performed between the treatment protrusions 83 of the

treatment elements

81a and 81c, and the scalp sandwiched between the

treatment elements

81a and 81c is moved in the rotation direction of the

treatment elements

81a and 81c.

Further, when the surgical elements 81a to 81d are further rotated by 90 degrees, the centers P1 and P2 of the surgical element base portions 82 of the

surgical elements

81a and 81b rotating in the same direction are closest to each other. When the space between the

surgical elements

81a and 81b is viewed locally, the

surgical elements

81a and 81b circulate so as to pass each other while being close to each other. Thus, the scalp is sandwiched between the

surgical elements

81a and 81b approaching at the same timing, and the scalp can be twisted by passing the

surgical elements

81a and 81b. When such

surgical elements

81a and 81b are brought into contact with the scalp, the scalp is cared for (massaged) by effectively moving the scalp of the user in accordance with the movement of the

surgical elements

81a and 81b. The In addition, also in the

surgical elements

81c and 81d, the same pinching and twisting motion as the

surgical elements

81a and 81b is performed.

Further, when each of the surgical elements 81a to 81d is rotated 90 degrees (rotated 180 degrees from the state shown in FIG. 9), the

surgical elements

81b and 81d sandwich and grind between the

surgical elements

81b and 81d. At this time, the

surgical elements

81b and 81d are in the closest state in the left-right direction, and pinching is performed between the surgical protrusions 83 of the

surgical elements

81a and 81c. At this time, the scalp is moved toward the

surgical elements

81b and 81d by being sandwiched between the

surgical elements

81a and 81c. Further, the

surgical elements

81b and 81d move the user's scalp in the same direction so as to be continuous with the movement of the scalp toward the

surgical elements

81b and 81d.

As described above, in the example shown in FIG. 9, different types of movement can be given to the scalp according to the rotation angle of each of the surgical elements 81a to 81d (centers P1 to P4). It can contribute to improvement of care effect.

Next, the stopping means that is a characteristic part in the scalp care device 10 of the present embodiment will be described in detail. The stop means of the present embodiment stops the driving of the motor 32 and the gears 41 to 46 and the

shafts

47 and 56 by the motor 32 in a state where the treatment head portion 12 is detached from the apparatus main body portion 11.

The stopping means includes a lever member 36a that is long in one direction (vertical direction) and a spring member 36b that urges the lever member 36a in the attaching / detaching direction (detaching direction) of the treatment head portion 12.

As shown in FIGS. 3 and 6, the lever member 36 a is fitted with a support portion 40 f formed of two curved wall portions provided on the gear base 40 by its own hook portion. Further, one end side (upper side) of the lever member 36a can be inserted into an insertion hole penetrating along the vertical direction formed in the gear base 40 and the motor base 30 when fitted to the support portion 40f. It is. For this reason, the one end part of the lever member 36a can contact | abut with the said lever metal fitting 34d. More specifically, when the gear base 40 and the motor base 30 are fitted, one end (upper side) of the lever member 36a is brought into contact (engaged) with the lever fitting 34d.

Further, as shown in FIG. 3, the other end side (lower side) of the lever member 36a is a through-hole penetrating along the vertical direction formed at a corresponding position in the vertical direction of the waterproof base 50. It is in a state where it is always inserted. Since an O-ring 36c is interposed between the through hole and the lever member 36a, water and the like are prevented from entering the main body housing 13.

Also, the spring member 36b made of a coil spring interposed between the support portion 40f and the lever member 36a is extrapolated. One end in the vertical direction of the spring member 36b contacts the lower surface of the gear base 40, and the other end in the vertical direction contacts a large-diameter portion formed at an intermediate position in the vertical direction of the lever member 36a. For this reason, the lever member 36a is urged downward in the vertical direction (removal direction of the treatment head portion 12) in response to the urging force of the spring member 36b. Incidentally, when the treatment head portion 12 is removed, the other end side (lower side) of the lever member 36a is exposed as shown in FIG.

Further, as described above, the protrusion 64b of the head base 62 is formed at a position corresponding to the lever member 36a in the vertical direction. When the treatment head portion 12 (head base portion 62) is attached to the apparatus main body portion 11 side, the lever member 36a is pushed by the protrusion 64b in a direction to bring the lever fitting 34d close to the motor fitting 34c. Thereby, each metal fitting 34c and 34d is contact | abutted, and the electric power from the storage battery 33 can be supplied to the motor 32. FIG. On the other hand, in a state where the treatment head portion 12 is detached from the apparatus main body portion 11, the lever member 36a is moved in the removal direction of the treatment head portion 12 by the urging force of the spring member 36b to separate the

metal fittings

34c and 34d. Thereby, the power supply path between the motor 32 and the storage battery 33 is interrupted.

The shape of the head base 62 and the apparatus main body 11 (main body housing 13) side to which the head base 62 is attached are substantially the same. For this reason, it is possible to attach the head base portion 62 even when the head base portion 62 is rotated approximately 90 degrees in the circumferential direction with respect to the apparatus main body portion 11. Accordingly, by providing the protrusions 64b formed at the same distance from the center position of the head base portion 62 at intervals of about 90 degrees in the circumferential direction, the treatment head regardless of the orientation of the treatment head portion 12 (head base portion 62). When the portion is attached, the lever member 36a can operate with any of the protrusions 64b.

Next, characteristic actions and effects of this embodiment will be described.

(1) Stopping means for stopping the driving of the motor 32 in the state where the treatment head part 12 is detached from the apparatus main body part 11 is provided. Thus, in the state where the treatment head portion 12 is removed from the apparatus main body section 11, for example, even if the switch operation member 22 is pressed, the drive of the motor 32 remains stopped. It is possible to notify that the treatment head portion 12 is detached. Further, since the drive of the output shaft 56 exposed to the outside of the apparatus main body 11 is stopped with the treatment head portion 12 removed, the use of the output shaft 56 exposed can be prevented and safety is improved. Can be made.

(2) The lever member 36a constituting the stop means is moved in a direction away from the apparatus main body 11 in conjunction with the removal of the treatment head portion 12, whereby each metal fitting is provided in the power supply path to the motor 32. The mechanical contact state of 34c, 34d is switched to the non-contact state, and the drive of the motor 32 is stopped. By setting it as such a structure, the electric power supply path between the storage battery 33 and the motor 32 can be interrupted | blocked reliably.

(3) The stopping means has a lever member 36a that is urged in the same direction as the attaching / detaching direction of the treatment head portion 12 and is movably provided. And the lever member 36a stops the electric power supply to the motor 32 with the urging | biasing force which urges | biases the lever member 36a in the state from which the treatment head part 12 was removed from the apparatus main body part 11. FIG. Further, the lever member 36 a is pressed in a direction against the urging force that urges the lever member 36 a in a state where the treatment head portion 12 is attached to the apparatus main body portion 11, and supplies electric power to the motor 32. Here, since the reaction force due to the pressing of the surgical elements 81a to 81d of the scalp care device 10 is the direction in which the lever member 36a can supply electric power (attachment direction) and the moving direction, the

metal fittings

34c and 34d are more They can be reliably brought into contact with each other. Thereby, the motor 32 can be reliably driven in a state where the treatment head portion 12 is attached to the apparatus main body portion 11.

(4) The lever member 36a that constitutes the biased member of the stop means is configured to operate the operating elements 81a to 81d (the rotation base 55) in the direction orthogonal to the connecting shaft 47 that is the operating axis of the operating elements 81a to 81d. From the position perpendicular to the axis. With such a configuration, the lever member 36a can move in the axial direction (vertical direction) without hindering the operation of the treatment elements 81a to 81d (the rotation base 55). For this reason, when the treatment head portion 12 is detached from the apparatus main body portion 11, the lever member 36a is reliably moved by the spring member 36b, so that the mechanical contact state of the

metal fittings

34c, 34d is changed from the mechanical contact state to the non-contact state. Power supply to can be cut off.

In addition, you may change the embodiment of this invention as follows.

-In the above-mentioned embodiment, although it was set as the structure which detects attachment or detachment of the treatment head part 12 with respect to the apparatus main body part 11 by the contact state of the

metal fittings

You may employ | adopt the structure to detect.

In the above embodiment, the lever member 36a as the biased member that constitutes the stopping means is disposed at a position outside the region connecting the connecting shafts 47 connected to the rotation base 55 with the shortest line segment. However, it is not limited to this. For example, you may employ | adopt the structure which arrange | positions the said lever member 36a in the position inside the area | region which connects each connecting shaft 47 with the shortest line segment. However, in the case of this configuration, it is preferable to arrange the lever member 36a at a position that does not hinder the operations of the rotary base 55 and the treatment elements 81a to 81d.

In the above embodiment, the lever member 36a is pressed upward by one protrusion 64b of the four protrusions 64b to bring the lever fitting 34d and the motor fitting 34c into contact with each other. Not exclusively. For example, a lever member 36a and a spring member 36b are provided so as to correspond to all of the four protrusions 64b, and the

metal members

34c and 34d come into contact with each other when the lever members 36a are pressed by the protrusions 64b. A configuration may be adopted.

In the above embodiment, the four projecting portions 64b are provided on the opposite side of the rib portion 64a of the crosspiece 64 so as to be spaced approximately 90 degrees in the circumferential (surface) direction, but this is not restrictive.

In the above embodiment, although not particularly mentioned, for example, the attachment / detachment state of the treatment head portion 12 is detected in accordance with an electrical or mechanical load variation of the motor 32 caused by attachment / detachment of the treatment head portion 12 to / from the apparatus main body portion 11. Thus, a configuration for controlling power supply to the motor 32 as a drive source may be employed.

In the above embodiment, the connection shaft 47 and the output shaft 56 are offset in the direction perpendicular to the axis (plane direction). 47 and the output shaft 56 may rotate on the same axis. In this case, the surgical elements 81a to 81d rotate about the arrangement centers (P1 to P4) of the surgical projections 83 of the surgical elements 81a to 81d, so that the surgical elements 81a to 81d and the cover portion 61 are separate. It is desirable to be.

In the above embodiment, the surgical elements 81a to 81d are configured to operate in a direction (surface direction) orthogonal to the connecting shaft 47 (output shaft 56). However, the configuration is configured to operate the surgical elements 81a to 81d in the axial direction. It may be adopted. With such a configuration, it is possible to give a stimulus that strikes the user's scalp. Further, a configuration in which the surgical elements 81a to 81d are moved in the axial orthogonal direction and the axial direction may be employed.

In the above embodiment, the cover portion 61 and the treatment elements 81a to 81d constituting the treatment head portion 12 are integrally formed with a flexible member, but a separate structure may be employed. However, it is desirable that the treatment projections 83 of the treatment elements 81a to 81d are formed of a flexible member (elastic member) in any configuration.

In the above embodiment, the four surgical elements 81a to 81d are provided, but the number thereof may be arbitrarily changed. Further, although the four treatment protrusions 83 are provided on the treatment elements 81a to 81d, the number thereof may be arbitrarily changed. For example, the number of the treatment protrusions 83 may be different in each of the treatment elements 81a to 81d. . Furthermore, although it was set as the structure which provided the small diameter 3 processus | protrusion 83a at the front-end | tip of each treatment procession 83, the number may change arbitrarily, for example, the number of processus | protrusion 83a may differ in each process procession 83. Further, a configuration in which the protrusion 83a is omitted may be employed.
