  Embodiments of the present invention will be described below with reference to FIGS. In this example, front, rear, top, bottom, left and right are defined based on the postures of FIGS. Reference numeral 1 denotes a brush device according to the present invention. The brush device 1 includes a main body 2 that is a driving unit and a brush unit 3 that is detachably held with respect to the main body 2.

  The main body 2 includes an outer shell 4 made of synthetic resin or the like, a secondary battery (not shown), a control circuit (not shown), an electric motor 5 operated by the secondary battery and the control circuit, and the electric motor. And a reciprocating drive means 6 for converting the rotation of the drive shaft 5A into a reciprocating motion. The outer shell body 4 has a head portion 7 and a gripping portion 8, the outside of the gripping portion 8 is covered with a cover body 9, and a switch operating portion is provided on the front side of the gripping portion 8. 10 is provided. The electric motor 5 is held by the first holding frame 11, and the drive shaft 5 </ b> A of the electric motor 5 protrudes from the upper end of the first holding frame 11. The reciprocating drive means 6 is held by a second holding frame 12 having an opening 12A in the front, and the first holding frame 11 is attached to the second holding frame 12. It is attached. Then, in the state where the first holding frame 11 is fixed to the second holding frame 12 in this way, a gear (not shown) attached to the drive shaft 5A of the electric motor 5 held by the first holding frame 11 Meshes with the gear 6A on the input side of the reciprocating drive means 6. Thus, the rotation of the electric motor 5 is configured to be transmitted to the reciprocating drive means 6. Then, the rotation transmitted from the electric motor 5 is decelerated by the plurality of gears of the reciprocating drive means 6, and the decelerated rotation is converted into a reciprocating motion to move the reciprocating member 6B in the front-rear direction (in FIG. 3). It is configured to reciprocate in the left-right direction). Further, the second holding frame 12 is fixed to the rear outer shell 4A of the outer shell 4 with screws or the like. The opening 12A is closed by a waterproof film 13 formed in a diaphragm shape with synthetic rubber or the like. Then, the outer peripheral portion 13A of the waterproof film 13 is sandwiched between the opening edge 12B of the opening 12A and the opening edge 4D of the front outer shell body 4B having the opening 4C, and is fastened and fixed with screws or the like. The outer shell 4 is fixed in a watertight manner. Further, the central portion 13B of the waterproof film 13 is watertight between the reciprocating member 6B and the hook holding body 14 by being fastened and fixed with screws or the like while being sandwiched between the reciprocating member 6B and the hook holding body 14. Is held in. Further, a hook 15 formed by bending a metal wire or the like is attached to the hook holder 14. Then, by operating the electric motor 5, the reciprocating member 6 of the reciprocating driving means 6 reciprocates in the front-rear direction, and accordingly the diaphragm-like waterproof film 13 is bent and attached to the hook holding body 14. The hook 15 is configured to reciprocate in the front-rear direction. Around the opening edge 4D of the front outer shell body 4B, a frame body 4E protrudes forward so as to surround the opening edge 4D and is formed in an approximately elliptical shape. A locking receiving portion 4F protruding outside the frame body 4E is formed.

  The brush portion 3 is integrally formed of flexible synthetic resin or the like. The brush portion 3 includes a base portion 16 and a plurality of protrusions 17 provided on the base portion 16. The base portion 16 is substantially elliptical when viewed from the front, and has a shape in which the center smoothly swells forward. The base portion 16 has a rib 16A integrally formed over the entire periphery from the outer periphery to the rear, and a locking portion 16B that engages with the locking receiving portion 4F is formed inside the rib 16A. ing. Further, at the upper end and the lower end of the base portion 16, a picking portion 16 </ b> C for picking up when the brush portion 3 is attached to and detached from the main body 2 is formed. Further, on the back surface of the base portion 16, a groove 16D extending in the vertical direction is formed at the center thereof, and a hook receiving portion 16E for receiving the hook 15 is formed at the center portion. Further, the protrusion 17 includes a plurality of long protrusions 18 formed on the outer peripheral portion of the base portion 16, and a plurality of middle protrusions formed in a ring shape at an intermediate portion of the base portion 16 inside the long protrusion 18. 19 and a plurality of short protrusions 20 formed in a ring shape at the center of the base 16 which is the inside of the middle protrusion 19. As shown in FIG. 4A, in the state where the base portion 16 is not bent, the long protrusion 18 has the highest height, the intermediate protrusion has a medium height, and the short protrusion 20 has a high height. Is the lowest. When the tips of these protrusions 17 are connected, a concave curved surface is formed. Further, the long protrusion 18 and the short protrusion 20 are formed in a substantially bar shape with a slightly narrowed tip side, and the tip is formed in a round shape. Further, the middle protrusion 19 is formed in a substantially conical shape having a thin tip side and a thick base end side. The tip of the middle projection 19 is formed to be narrower than the tips of the long projection 18 and the short projection 20, and the base end of the middle projection 19 is from the base ends of the long projection 18 and the short projection 20. It is also formed thick. As a result, the middle protrusion 19 is formed to be more difficult to bend than the long protrusion 18 although it is bent by an external force. 2 to 5, if all the protrusions 17 are described, there is a risk that explanation will be difficult due to complicated lines and complicatedness. Therefore, in FIG. Of these, only the long protrusion 18 formed on the outermost peripheral portion of the base portion 16 is shown, only the long protrusion 18 having a cross section in FIG. 3 is shown, and in FIGS. Only the protrusions 17 are shown, and the other protrusions 17 are omitted.

  Next, the operation of this embodiment will be described. First, the user grasps the brush portion 3 and exposes the hook receiving portion 16E formed on the back surface of the base portion 16 of the brush portion 3 in the opening 4C of the front outer shell body 4B of the main body 2. After being hooked on the hook 15, the brush portion 3 is attached to the main body 2 by engaging the locking portion 16B with the locking receiving portion 4F. When the brush unit 3 is attached to the main body 2 in this manner, the user grips the grip unit 8 and operates the switch operation unit 10 to activate the motor 5 and The drive shaft 5A rotates. Then, the rotational movement of the drive shaft 5A is decelerated by the reciprocating drive means 6 and then converted into the reciprocating movement, whereby the reciprocating member 6B of the reciprocating driving means 6 and eventually the hook attached to the reciprocating member 6B. The holding body 14 and the hook 15 reciprocate in the front-rear direction. Since the opening 4C of the front outer shell body 4B is sealed by the waterproof film 13, water can be prevented from entering the main body 2 from the opening 4C. Further, since the waterproof film 13 is formed in a diaphragm shape by synthetic rubber or the like, the sealing state of the opening 4C is changed by bending with the reciprocating motion of the reciprocating member 6B and the hook holding body 14. Can keep. When the hook 15 reciprocates in the front-rear direction, the central portion of the base portion 16 of the brush portion 3 having the hook receiving portion 16E hung on the hook 15 also reciprocates in the front-rear direction. At this time, the engaging portion 16B formed on the outer peripheral edge of the base portion 16 is engaged with the engaging receiving portion 4F, so that the outer peripheral edge of the base portion 16 has a positional relationship with the main body 2. Since it is substantially fixed, even if the central portion of the base 16 reciprocates in the front-rear direction, the base 16 does not move as shown in FIGS. 4A and 4B because the outer peripheral edge of the base 16 does not move. Between states, it will bend repeatedly in the direction orthogonal to the surface direction of the base 16. At this time, since the base portion 16 is bent, the protrusion 17 formed integrally with the base portion 16 also moves. Specifically, in the no-load state, each of the protrusions 17 is in a state in which the tip is widened (open state) as a whole in the state of FIG. In the state of FIG. 4B in which the base portion 16 is most recessed, the tip is narrowed (closed state) as a whole. The base portion 16 has the groove 16D formed on the back surface thereof, and the position where the groove 16D is formed becomes a starting point of bending, so that the base portion 16 is more easily bent.

  When the protrusion 17 that operates in this way is pressed against the scalp H of the human body to perform hair washing or the like, the operation is performed as shown in FIG. That is, in the state of FIG. 5A in which the base portion 16 protrudes most, the tip of each projection 17 is connected to form a concave curved surface. In this state, the tip of each projection 17 is formed into a convex curved scalp H or the like. When pressed, the projections 17 are hardly bent and the tips thereof are in contact with the scalp H. Then, when the base 16 is retracted and recessed by the reciprocating drive means 6, the state shown in FIG. That is, of the projections 17, the middle projection 19 which is shorter than the long projection 18 and difficult to bend is pressed from the state of FIG. ), The tip moves so as to rub the scalp H, but is washed and massaged so that the scalp H is rubbed by the middle projection 19. In particular, in this example, the tip of the middle protrusion 19 is relatively thin and its base end is formed in a relatively thick conical shape. Since it is sharp, the scalp H is scrubbed or stimulated by being scratched by the middle protrusion 19 and is well cleaned and massaged. In addition, when the long protrusion 18 is longer than the intermediate protrusion 19 and is bent so that the tip thereof is in contact with the scalp H, the swinging direction from the state of FIG. Will be greatly bent. At this time, the portion from the distal end of the long protrusion 18 to a portion near the proximal end is in contact with the scalp H, and a restoring force acts on the long protrusion 18 in a bent state so that the scalp H can be grasped. It is washed and massaged under various stimuli. In particular, in this example, the long protrusion 18 has a relatively thick tip and a base that is relatively thin, so that it is more easily bent. The contact area with respect to the scalp becomes larger, and the scalp H is well washed and massaged by the gripping stimulus. In addition, since the long projection 18 is easily bent, the middle projection 19 can be surely kept in contact with the scalp H at all times, whereby the stimulation by the middle projection 19 is always given to the scalp H. You can continue. Further, the short protrusion 20 shorter than the middle protrusion 19 is separated from the scalp H in the state of FIG. 5B even when it is in contact with the scalp H in the state of FIG. is doing. This is because the curvature of the concave curved surface connecting the tip of the middle projection 19 and the tip of the short projection 20 is larger than the curvature of the scalp H in the state of FIG. In particular, this also facilitates that the short protrusion 20 repeats contact and separation with the scalp H because the middle protrusion 19 is more difficult to bend in this example. The scalp H is washed and massaged so as to be hit by the short protrusions 20 as the short protrusions 20 are repeatedly brought into and out of contact with the scalp H. In particular, in this example, the tip of the short projection 20 is relatively thick and the base end is formed in a substantially thin rod shape, so that the short projection 20 is more easily bent. By bending when hit, not only can the scalp H be stimulated more than necessary, but the pain is not felt, and the proximal end of the short protrusion 20 becomes relatively thin. Therefore, the base end portion of the short protrusion 20 can be prevented from preventing the base portion 16 from being bent. As described above, the long protrusion 18, the middle protrusion 19, and the short protrusion 20 constituting the protrusions 17 give different stimulations to the scalp H, so that the scalp H can be better massaged and washed. it can.

  In addition, since the said brush part 3 becomes dirty or damaged by repeated use, it will be necessary to replace | exchange suitably. And when removing this brush part 3 from the said main body 2, when the user picks the said knob | pick part 16C and pulls it forward, the said latching | locking part 16B will remove | deviate from the latching receiving part 4F. Thus, after the said latching | locking part 16B remove | deviates from the latching receiving part 4F, the said brush part 3 remove | deviates from the said main body 2 by pulling up the said brush part 3 upwards. Then, the brush device 1 can be used again by attaching the new brush unit 3 or the cleaned brush unit 3 to the main body 2 according to the procedure described above.

As described above, according to the present invention, the frame 4E of the outer shell 4 of the main body 2 which is the driving unit provided with the reciprocating driving means 6 is crossed with the base 16 made of a flexible material and the surface of the base 16. A plurality of long projections 18 provided on the outer peripheral portion of the base portion 16, a plurality of middle projections 19 provided at an intermediate portion of the base portion 16 so as to intersect the surface of the base portion 16, and the surface of the base portion 16 comprising a plurality of short projections 20. which is provided in a central portion of the base portion 16 so as to intersect the brush part 3, freely is held detachably in state like the positional relationship relative to the main body 2 is substantially fixed, the base 16 Is formed so as to be repeatedly bent in the direction perpendicular to the surface thereof by the reciprocating drive means 6, and the middle protrusion 19 is formed lower than the long protrusion 18 and the short protrusion 20 is formed lower than the middle protrusion 19. As a result, the bending of the base portion 16 of the brush portion 3 by the reciprocating drive means 6 is achieved. Accordingly, by repeatedly opening and closing the plurality of protrusions 17, the scalp H is rubbed by the short protrusions 20 so that the scalp H is rubbed by the middle protrusions 19 so that the scalp H is gripped by the long protrusions 18. It will be washed and massaged so that it can be beaten. In the present invention, since the middle projection 19 is formed in a substantially conical shape, the middle projection 19 is less likely to bend in the swinging direction, and can give a stimulus such that the scalp H is rubbed better. It is. In addition, the present invention forms the long protrusion 18 in a substantially rod shape and is formed thinner than the base end portion of the intermediate protrusion 19 as a whole, so that the long protrusion 18 is more easily bent than the intermediate protrusion 19, The scalp H can be stimulated to be gripped better. Further, the present invention is that the short protrusion 20 is formed in a substantially rod shape and is formed thinner than the base end portion of the middle protrusion 19 as a whole, so that the base end portion of the short protrusion 20 causes the base portion 16 to bend. Not only can it be prevented, but also the short projection 20 bends when it hits the scalp H, so that the scalp H is not given any irritation so as not to feel pain. It is something that can be done.

  In addition, this invention is not limited to the above embodiment, A various deformation | transformation is possible within the range of the summary of invention. For example, in the above-described embodiment, the brush portion is integrally formed with the base portion and the protrusion.
