JP 2003-93415 (0011-0013, FIG. 1)

  However, since the above switch is provided not on the toothbrush side of the gripping body but on the outer end (on the opposite toothbrush side), when the gripping body is gripped with one hand, the switch is turned on / off with the other hand. In addition, it is impossible to operate the switch with the thumb of the gripped hand, which is inconvenient. In addition, the toothbrush body is a special product that has a built-in vibration motor in the cavity near the neck and joins the fitting cylinder to one side of the gripping body. In addition to being forced to replace the whole, it is necessary to expose the vibration motor, which is an internal component, and then incorporate it into a new toothbrush body.

  Accordingly, a first problem of the present invention is to provide a mechanical switch device that can be operated by a thumb operation of a gripped hand in the compact storage structure.

  The second object of the present invention is to provide an electric toothbrush that can eliminate the need to remove the vibration motor in the case when replacing the toothbrush.

  The present invention relates to a switch device having a first terminal fitting connected to one of the electrodes of the battery and its power supply object, and a second terminal metal fitting connected to the other electrode of the battery and power supply object. A direction in which the elastic connecting portion of the first terminal metal fitting and the convex portion of the second terminal metal fitting are positioned to face each other and are interposed between the elastic contact portion and the convex portion and substantially perpendicular to the convex portion. An insulating switch operating portion having a slidable partition wall, and the partition wall has a convex recess at the first position and a convex recess at the second position. And a penetrating cavity that allows the inserted convex portion to elastically contact the elastic contact portion.

  In the switch device having such a configuration, when the partition wall portion is in the first position, the switch-off state in which the engaging concave portion and the convex portion are engaged can be maintained, and the insulating switch operating portion is operated to operate the partition wall portion. When the second position is reached, the engaging concave portion is removed from the convex portion, and the through hole is inserted into the convex portion, and the elastic contact portion is elastically contacted through the through hollow portion. -The on state can be maintained. Then, when the insulating switch operating portion is operated and the partition wall portion is in the first position, the penetration empty portion is detached from the convex portion, and the engaging concave portion is fitted into the convex portion, so that the switch-off can be continued.

  In this way, since the convex portion of the second terminal fitting is switched and fitted into the engaging concave portion and the penetrating empty portion of the partition wall portion movable between the elastic connection portion, a click feeling can be exhibited in the switch operation. At the same time, when the switch operation unit is not operated, the on state or the off state can be maintained. The first terminal fitting and the second terminal fitting can be arranged between the battery and the power supply target body, and the switch operation unit can be operated with the thumb while being held with one hand. Moreover, since it can be comprised with two terminal metal fittings and the switch operation part in which a partition part interposes between this, a compact storage structure is realizable.

  It is desirable that the elastic contact portion is a leaf spring piece, and the partition wall portion has a guide groove that relatively guides the leaf spring piece with the slide. Relief of elastic leaf spring pieces can be regulated by guide grooves, and deformation of leaf spring pieces due to long-term use can be suppressed. As a result, blurring of the partition wall in the sliding direction can be suppressed. The accuracy of fitting with can be maintained.

  The insulating switch operation unit includes a pair of opposing leg portions having opposite support shafts, an operation plate portion extending in both directions perpendicular to the support shaft, and one end of the operation plate portion. It is desirable to integrally have a partition wall portion curved substantially in an L shape.

  Since the sliding of the partition wall can be realized by the seesaw operation of the operation plate, the switch operation surface can be arranged on one side of the battery or the power supply object.

  Here, it is desirable that the engaging recess is formed on the distal end side of the partition wall portion, and the through space is a through hole formed on the base side of the partition wall portion. Since the convex part fits shallowly with the engaging concave part and the convex part fits deeply with the through hole, the penetrating empty part is formed on the base side of the partition wall part. Is less likely to occur, and durability associated with switch operation can be improved.

  As the detachable toothbrush vibration device, the above switch device is used, and the object to be fed is a vibration motor having an eccentric weight, and a convex portion, a partition wall portion and an elastic contact portion are arranged between the vibration motor and the battery. The case body includes a first bifurcated claw portion for detachably holding the neck portion of the toothbrush, and a second bifurcated claw portion for detachably holding the handle portion of the toothbrush at the abdomen. And integrated.

  Since vibration from the vibration motor is well transmitted from the first bifurcated claw portion to the neck portion of the toothbrush through the case body, a commercially available toothbrush can be used as an electric toothbrush. One detachable toothbrush vibration device can be shared by several family members, and the price can be reduced compared to the case where each person purchases a conventional electric toothbrush. Further, when replacing the toothbrush, the vibration motor is not exposed and remains built in the case main body, and can be easily replaced only by an attaching / detaching operation by the bifurcated claw portion.

  Here, when the case body has a tail portion extending rearward from the second bifurcated claw portion and straddling the handle portion, even when a finger of one hand holding the handle portion is inadvertently hooked on the second bifurcated claw portion. Since the second bifurcated claw portion is not at the end of the handle portion, it is difficult to come off from the handle portion.

  In addition, when the motor cover that covers the vibration motor housing portion of the case body is supported, the support shaft is rotatably supported by the vibration motor housing portion and the motor cover, and the operation plate portion covers the motor cover, In the sliding of the part, there are a case where the tip abuts against the case main body and a case where the end of the operation plate abuts against the motor cover, and the sliding stroke of the partition part can be limited.

  There is an outer cover that closes both housing parts by interposing an O-ring at an opening edge that goes around the battery housing part and the vibration motor housing part of the case body. The outer cover includes an on button part and an off button part of the operation plate part. It is desirable to have a window with a seal that faces the surface.

  The operation plate is sandwiched between the motor cover and the outer cover, can be operated with a seesaw via a window seal, and has a double waterproof structure with an O-ring or window seal.

  According to the switch device of the present invention, it is possible to realize a compact storage structure with a small number of parts, and the switch operation is possible by the thumb operation of the gripped hand. According to the vibration device for a detachable toothbrush of the present invention, a commercially available toothbrush can be used as an electric toothbrush.

The leg piece 51 is inserted along the _third guide groove G3 shown in FIG. As shown in FIG. 12, the convex portion 52 and the folded elastic piece 43 face each other and elastically contact each other between the first hollow partition wall 14b and the second hollow partition wall 14c.

  The vibration motor 60 is fitted and installed in the vibration motor housing 13 formed in the lower half, and the minus terminal 61 and the plus terminal 62 protruding from the anti-eccentric weight end of the motor case face the battery B side. The vibration motor 60 is covered and sealed with a resin dome-shaped motor cover 70 shown in FIGS. Here, the dome-shaped motor cover 70 integrally includes an additional ceiling portion 72 that seals the solder connection portions of the terminals 61 and 62 and the solder piles 33 a and 53, in addition to the ceiling portion 71 that covers the vibration motor 60. Further, the insulating switch operation unit 80 shown in FIGS. 15 and 16 is covered on the dome-shaped motor cover 70.

  The insulating switch operation unit 80 is a molded product of an insulating resin, and a pair of opposed leg portions 81 and 82 having opposed shafts 81a and 82a, and the support shafts 81a and 82a straddling them. An operation plate portion 83 extending in both directions in the orthogonal direction and a partition wall portion 84 curved in an L shape from one end of the operation plate portion 83 are integrally provided. An on button portion 83a is bulged on the partition wall portion 84 side on the operation plate portion 83, and an off button portion 83b is bulged on the opposite side. The support shafts 81 a and 82 a are rotatably fitted between bearing holes 71 a and 71 b formed at the lower end of the dome-shaped motor cover 70 and the upper end edge 13 a of the vibration motor housing portion 13.

  When the dome-shaped motor cover 70 and the insulating switch operating portion 80 are assembled to the case body 10, the operation plate 83 of the insulating switch operating portion 80 is placed on the dome-shaped motor cover 70 as shown in FIG. As shown in FIG. 17, the gap between the opposing leg portions 81 and 82 of the insulating switch operation portion 80 is added to the ceiling portion 72 so as to be narrower than the ceiling portion 71 and inserted in the longitudinal direction (bus line direction). As shown in (B), the support shafts 81a and 82a can be fitted in contact with the hole walls of the bearing holes 71a and 71b. After that, as shown in FIG. 17C, the partition wall 84 is placed between the convex portion 52 and the folded elastic piece 43 in the terminal fitting loading portion 15 while maintaining the posture in which the partition wall portion 84 is pushed up by pressing the off button 83b. At the same time, the dome-shaped motor cover 70 is fixed to the upper end edge 13a of the vibration motor housing 13 where the adhesive has been applied, as shown in FIG. Since the notched bearing holes 71a and 71b are surrounded by the upper edge 13a, the support shafts 81a and 82a are not detached from the bearing holes 71a and 71b.

  Here, the partition wall 84 has a guide groove 84 a that relatively guides and guides the distal end side of the folded elastic piece 43 with the seesaw motion of the insulating switch operation unit 80. The partition wall 84 includes a through hole H in which the convex portion 42 is fitted on the base side and a blind hole h in which the convex portion 42 is fitted on the tip side.

As shown in FIGS. 4 and 5, an O-ring 17 is fitted into the upper edge of the wall surrounding the vibration motor housing part 13, the battery housing part 14, and the terminal fitting loading part 15 of the case body 10. Further, as shown in FIG. 8A, outer cover hooking claws K ₁ and K ₂ are integrally formed on both sides of the case body 10 in the longitudinal direction. Further, as shown in FIG. 18, the outer cover 20 covering the case body 10 has a semi-cylindrical shape, and latching protrusions P ₁ , P engaging the outer cover latching claws K ₁ , K ₂ at both ends thereof. ₂ and a rectangular window 21 at a corresponding position facing the on-button part 83a and the off-button part 83b of the operation plate part 83. The rectangular window 21 is closed with a waterproof seal 22 with a switch operation mark attached to the periphery thereof.

  In the detachable toothbrush vibration device 1 having such a configuration, vibration from the vibration motor 60 is well transmitted from the first bifurcated claw portion 11 to the neck portion 3e of the toothbrush 2 through the case body 10, and thus a commercially available toothbrush. But it can be used as an electric toothbrush. Further, when replacing the toothbrush 2, the vibration motor 60 is not exposed and remains built in the case body 10, and can be easily replaced by an attaching / detaching operation using the bifurcated hook portions 11, 12. One detachable toothbrush vibration device 1 can be shared by several family members, and the price can be reduced compared with the case where each person purchases a conventional electric toothbrush.

  Further, in the mechanical switch device according to the present example, as shown in FIG. 19A, when the convex portion 52 is fitted in the blind hole h of the partition wall portion 84, the convex portion 52 is not in contact with the folded elastic piece 43. Therefore, the switch-off state can be maintained, and when the on-button portion 83a is pushed in through the waterproof seal 22 with the thumb of the hand holding the case body 10 from such a state, the switch operation portion 80 swings in the arrow X direction. Then, as shown in FIG. 19B, the blind hole h comes out relatively from the convex portion 52, and this time, the convex portion 52 is fitted into the through-hole H as shown in FIG. Since the front end side also enters from the opposite side of the through hole H, the convex portion 52 and the folded elastic piece 43 are elastically pressed in the through hole H, and the switch-on state can be maintained. On the other hand, in the switch-on state of FIG. 19C, the switch operation unit 80 swings in the direction of the arrow Y by pushing the off button portion 83b with the fingertip, and as shown in FIG. 52 and the return elastic piece 43 relatively come out of the through hole H, and this time, as shown in FIG. 19A, the convex portion 52 fits into the blind hole h and is in a non-contact state with the return elastic piece 43. The off state can be maintained.

  In this manner, the switch can be kept on or off by selectively fitting with respect to the through hole H or the blind hole h of the convex portion 52, and the switch with the thumb while holding the case body 10 with one hand. It can be operated and contributes to improved usability. Moreover, since it can be comprised with the two terminal metal fittings 40 and 50 and the switch operation part 80 in which the partition part 84 interposes between these, the terminal metal fitting loading part 15 may suffice as a substantially compact storage structure.

  In this example, since the guide groove 84a is formed in the partition wall 84, the escape of the folded elastic piece 43 can be restricted by the guide groove, and the deformation of the folded elastic piece 43 due to long-term use can be suppressed. By suppressing blurring in the sliding direction, the accuracy of fitting the convex portion 42 with the blind hole h or the through hole H can be maintained.

  The insulating switch operation unit 80 integrally includes an operation plate 81 and a partition wall 84 that is curved in an L shape, and the partition 84 can be slid by a seesaw operation of the operation plate 81. It can be placed on one side of the main body and is suitable for thumb operation.

  The convex portion 52 fits shallowly with the blind hole h, and the convex portion 52 fits deeply with the through hole H, but the through hole H is formed on the base side of the partition wall portion 84, so it fits into the partition wall portion 84. Excessive stress is less likely to occur at the time, and durability associated with switch operation can be improved.

  In this example, the dome-shaped motor cover 70 that closes the vibration motor housing portion 13 of the case body 10 is provided, and the support shafts 81a and 82a are rotatably supported by the vibration motor housing portion 13 and the dome-shaped motor cover 70, Since the operation plate portion 81 covers the dome-shaped motor cover 70, the end of the operation plate portion 81 is opposite to the dome-shaped motor cover when the tip of the partition portion 84 slides against the case body 10. 70, the sliding stroke of the partition wall 84 can be limited.

  And it has the outer cover 20 which interposes the accommodation part by interposing the O-ring 17 in the opening edge which goes around the battery accommodating part 14 and the vibration motor accommodating part 13 of the case main body 10, and this outer cover 20 is an operation board part. 81, the operation plate 81 is sandwiched between the dome-shaped motor cover 70 and the outer cover 20 so that the rectangular window 21 faces the on-button portion 83a and the off-button portion 83b. The seesaw can be operated through the 21 waterproof seals 22 and has a double waterproof structure with the O-ring 17 and the waterproof seal 22.

  Although the detachable toothbrush vibration device 2 includes the vibration motor 60, various detachable prime movers can be realized by using a geared motor instead.
