The outer case 4C is made of a case body that is slightly larger than the inner case 4A, and has a surface that faces the arcuate circumferential surface of the inner case 4A. The case lid 4B and the outer case 4C are welded and fixed to the inner case 4A, respectively.

  In FIG. 4, the brush unit 2 is formed of a plastic molded product in which a group of bristles 41 are integrally molded on the outer surface of a strip (plate) base 40. Positioning walls 42 bulge out along the longitudinal direction at the left and right center of the outer surface of the base 40, and inverted L-shaped first portions are formed at four locations near both ends in the longitudinal direction and at the left and right of the central portion in the left and right direction. One engaging body 43 is integrally provided as a protrusion. In the center of the base 40, there is an outlet 44 for sending negative ions.

  The procedure for mounting the brush unit 2 on the brush base 3 will be described. As shown in FIG. 1, the first engaging body 43 on the brush unit 2 side is fitted close to the mounting hole 22 on the brush base 3 side. Through the engagement operation (rightward in FIG. 1) and the second engagement operation (downward in FIG. 1) for slidingly fitting the brush unit 2 in a direction orthogonal to the first engagement operation, the first engagement body 43 is moved. The mounting hole 22 is engaged in a retaining manner. The second engagement operation is an operation in which the brush unit 2 is slid from the front end to the rear end of the brush base 3, and the second engagement operation may be configured to be engaged in a retaining manner only by the second engagement operation. it can.

  In the state of FIG. 3 in which both are engaged, the lateral claw 43a of the first engagement body 43 is received by the peripheral wall of the opening of the mounting hole 22, and the base 40 is moved toward the base wall 20 by the pulling action of the claw 43a. In close contact. Further, as shown in FIGS. 7 and 8, the positioning wall 42 of the base 40 is fitted into the loading recess 23, and the brush unit 2 does not wobble in the left-right direction with respect to the brush base 3 when combing hair. . As shown in FIGS. 1 and 3, the positioning wall 42 and the loading recess 23 are both curved so that the contact area with each other is increased. This increase in contact resistance can more reliably prevent wobbling in the front-rear and left-right directions of the brush unit 2.

  A lock structure is provided between the brush base 3 and the brush unit 2 in order to maintain the mounting state of the brush unit 2 with respect to the brush base 3 and lock and fix the brush unit 2 so as not to be removed. 5 and 7, the lock structure includes a contact portion 45 on the front end surface of the base 40, and a lock body 46 that receives the contact portion 45 and prevents the brush unit 2 from sliding in a separating direction. And an operating body 47 for unlocking the lock body 46, and disposed at the front end portion (upper end side in FIG. 1) of the base wall 20 of the brush base 3.

  As shown in FIG. 5, the lock body 46 is integrally formed in a gate shape with a stopper frame 48 that can be engaged with and disengaged from the contact portion 45 of the base 40 and a pair of left and right elastic arms 49 extending from the stopper frame 48. Yes. The operation body 47 is formed integrally with the stopper frame 48. As shown in FIG. 5, the lock body 46 is integrated with the brush base 3 by caulking and fixing the protruding end of the elastic arm 49 to a portion near the front end of the base wall 20, and the elastic arm 49 is elastically deformed in this state. Thus, the stopper frame 48 can be detachably displaced with respect to the contact portion 45. In order to allow the operating body 47 and the stopper frame 48 to be displaced, a recess 50 is formed at the front end of the base wall 20. As shown in FIGS. 1 and 3, the front end surface of the base 40 is a contact portion 45, so that it is not necessary to form a dedicated engagement protrusion or engagement recess on the base 40, and the engagement on the base 40 side It is possible to prevent the strength of the part from decreasing. In addition, the mold structure for forming the base 40 can be simplified.

  As described above, when the operation body 47 is integrally formed with the lock body 46 so as to protrude outside, the number of components of the lock structure can be reduced, and the lock body 46 and the operation body 47 are formed as separate parts. Compared to the case, the structural strength is increased and it is difficult to break. As shown in FIG. 2, since the operating body 47 is disposed at the front end of the base wall 20 farthest from the grip 4, the operating body 47 is not accidentally unlocked, and the user's clear intention is As long as the brush unit 2 is not being used, it can be well prevented that the brush unit 2 being used is unlocked and detached from the brush base 3. In the case of a structure in which only the stopper frame 48 and the operation body 47 which are part of the lock body 46 are integrally formed and the elastic arm 49 is omitted, the stopper frame 47 is pushed up between the front end wall of the base wall 20 and the stopper frame 48. It becomes the structure which arrange | positions the coil spring for this.

  As shown in FIGS. 2 and 9, the left-right width dimension B of the brush base 3 is sufficiently smaller than the front-rear dimension W of the brush base 3, so that the operation body 47 is unlocked by holding the brush base 3 with one hand. When the brush unit 2 is slid in the direction of separating with the other hand, or mounted, the entire circular arc surface of the brush base 3 can be received by the palm of the hand and firmly held. Therefore, the operation body 47 can be unlocked more reliably, and the brush unit 2 can be easily attached and detached.

  The power switch 10 is switched between an on state and an off state in conjunction with the opening / closing operation of the brush base 3 and the grip 4. That is, when the brush base 3 and the grip 4 are folded, they are in an off state, and when both the brushes 3 and 4 are expanded, they are switched to an on state. In order to position and hold the brush base 3 and the grip 4 in the folded state and the expanded state, a joint mechanism is incorporated in the connecting portion between the both 3 and 4, so the power switch 10 is not prepared during use. Will not switch to.

  In the state of FIG. 3 in which the hair brush is folded in a circle, the lower end of the bristle 41 protrudes to the lower surface side beyond the horizontal plane passing through the rotation center of the connecting shaft 5. Therefore, the upper surface of the grip 4, that is, the battery lid 32, is provided at a position recessed downward from a horizontal plane passing through the rotation center of the connecting shaft 5 by the amount of downward protrusion of the bristle 41.

  The facing distance E1 between the bristle 41 and the grip 4 in the folded state is smaller than the engagement length E2 between the first engagement body 43 and the second engagement body 22 in the first engagement operation, as shown in FIG. The dimensions are set. Therefore, even if the brush unit 2 slides in the separating direction for some reason and the engagement between the claw 43a and the mounting hole 22 is released, the bristle 41 is received by the grip 4, so that the brush unit 2 is further removed. Stop coming off. In order to prevent detachment, the engagement length E2 of all four sets of the first engagement bodies 43 and the second engagement bodies 22 need not be larger than the opposing distance E1 between the bristle 41 and the grip 4, and The engagement length E <b> 2 between the first engagement body 43 and the second engagement body 22 only in the set may be larger than the facing distance E <b> 1 between the bristle 41 and the grip 4.

  According to the hair brush configured as described above, the stopper frame 48 of the lock body 46 receives the contact portion 45 of the base 40 and slides and displaces in the direction in which the brush unit 2 separates (the upward direction in FIG. 1). Therefore, even if the brush falls on the floor and receives a large impact, the brush unit 2 does not come off from the brush base 3, and the mounting state of the brush unit 2 can be reliably maintained.

  When combing hair, the negative ions generated by the ion generator are ejected from the air outlet 44 of the brush unit 2 together with the air flow and adhere to the hair, so that water molecules floating in the air are adsorbed to the hair. It can be kept moist.

  In the case of cleaning the brush unit 2 with water, as shown by the imaginary line in FIG. 3, when the operating body 47 is pushed down in the direction of the arrow, the engagement between the stopper frame 48 and the contact portion 45 is released. In this state, the brush unit 2 can be separated by sliding operation.

  FIG. 10 shows another embodiment of the hair brush. There, the loading base 51 is formed to bulge on the base wall 20 of the brush base 3, and inverted L-shaped grooves are formed as the second engaging bodies 22 in the front and rear of the left and right side surfaces of the loading base 51. The base 40 on the brush unit 2 side is configured in a cap shape that is fitted on the loading base 51, and the first engagement body 43 that engages with the second engagement body 22 is formed in a circular protrusion around the inner surfaces of the left and right side walls. Formed into a shape. Furthermore, a protrusion 52 and an engagement hole 53 that are engaged with each other by a first engagement operation when the brush unit 2 is mounted on the brush base 3 are provided. The protrusion 52 in the illustrated example is provided in the base 40 of the brush unit 2, and the engagement hole 53 is formed as a long hole in the loading base 51.

Thus, when there is added a protrusion 52 and engaging holes 53, even when the brush unit 2 for some reason to separate slide, and engagement of both engaging body 22, 43 is released, the projection 52 Since the mounting posture can be maintained by the engagement holes 53, the brush unit 2 can be well prevented from falling off even when the facing distance E1 between the bristle 41 and the grip 4 is large when the brush body 1 is folded. The protrusion dimension of the protrusion 52 was set to be larger than the facing interval E1. Since others are the same as the previous embodiment, the same reference numerals are assigned to the same members, and descriptions thereof are omitted. The same applies to the following other embodiments.

FIG. 11 shows another embodiment relating to the lock structure. In FIG. 11A, the lock body 46 and the operation body 47 are configured as separate parts, and the lock body 46 is pressed and biased to the lock posture by the spring 54. The lock body 46 is slidably guided and supported by the brush base 3 and can be displaced between a locked posture for engaging with the contact portion 45 of the base 40 and an unlocked posture for releasing the engagement with the contact portion 45. . The operation body 47 is slidably guided and supported in a direction orthogonal to the lock body 46. When the operation body 47 is pushed in against the urging force of the spring 54, the lock body 46 is unlocked and the brush unit 2 is operated. Can be removed. The lock body 46 and the operation body 47 are joined via an oblique cam surface 55.

In FIG. 11 (b), and the operating body 47 rotates dial 57, this rotational operation is composed of a gear pair 58, 59 to tell the locking member 46, by rotating the rotary dial 57, the lock member 46 It can now be displaced between the locked position and unlocked position. The lock body 46 in this case is formed with a rack 60 that meshes with the final gear 59.

  In addition to the above-described embodiment, the first engaging body 43 and the second engaging body 22 may satisfy the relationship between the protrusions that can be engaged with each other and the holes or the recesses, and either of them may be a protrusion. The first engagement operation may be an oblique engagement operation. The second engagement operation does not need to be orthogonal to the first engagement operation, and an intersecting operation is sufficient. The present invention can also be applied to small electric devices such as a scalp massager with a brush incorporating a vibrator, a hair blosser, and a hair dryer. The present invention can be applied not only to human hair-styling brushes but also to grooming brushes for animals (dogs, cats, etc.).
