[First embodiment]
A first embodiment of a vibration unit for an oral cleaning tool according to this device will be described with reference to FIGS. FIG. 1 is a front view showing a state in which the clamper side unit of the vibration unit for an oral cleaning tool is mounted on a toothbrush. FIG. 2 is a plan view corresponding to the top view of FIG. 1 with the clamper-side unit not attached to the toothbrush, and FIG. 3 shows only the toothbrush handle with the clamper-side unit attached to the toothbrush. FIG. 4 is a cross-sectional plan view seen from above in FIG. 1, and FIG.

  The vibration unit for an oral cleaning tool shown in FIG. 1 is a vibration source that generates vibration by supplying power to a spring-type clamper 2 that can be mounted by sandwiching the handle portion 11 in a toothbrush 10 that is an oral cleaning tool. The clamper side unit 1 is provided with the vibration motor 3 fixed integrally therewith, and a power supply unit 4 that supplies power to the vibration motor 3. The power supply unit 4 is provided separately from the spring clamper 2 and is connected to the vibration motor 3 of the clamper side unit 1 by a power supply line 5. A thin and flexible two-core cord may be used for the feeder line 5.

  The power supply unit 4 includes a push button type switch for opening and closing a power feeding circuit to the vibration motor 3 and an elastic clip piece for fastening to clothes. The power supply unit 4 is a battery case that houses the battery 43 as indicated by a broken line, and has an opening with a lid (not shown) for replacing the battery 43 and a battery as indicated by a broken line. 43 has electrode pieces connected to the positive and negative poles 43 and wirings between the terminals of the switch 41 and the power supply line 5.

  The toothbrush 10 is an ordinary commercially available toothbrush composed of a handle portion 11 for gripping with a hand and a head portion 12 in which a brush 13 is implanted. The cross-sectional shape of the handle portion 11 is more than a circle, an ellipse, an ellipse, or a quadrangle. The clamper side unit 1 of the vibration unit for an oral cleaning tool can be attached to various shapes close to a polygon or the like.

  Details of the clamper side unit 1 will be described with reference to FIGS. The spring clamper 2 has a pair of connecting pieces 21a and 22a that extend in the direction of the other side and overlap each other on both sides in the width direction at the intermediate portion in the longitudinal direction of the two plate-like members 21 and 22. The two plate-like members 21 and 22 are rotatably connected around the rotation shaft 23 by a single rotation shaft 23 through the connection pieces 21a and 22a. .

  Coil springs inserted into the two plate-like members 21 and 22 through the rotary shaft 23 so that the front portions extending from the connecting portion to one side (leftward in FIG. 2) orthogonal to the rotary shaft 23 are closed to each other. 24 (see FIG. 4) provides rotational force, and the front portion thereof is gripping portions 21 b and 22 b that sandwich (hold) the handle portion 11 of the toothbrush 10. Further, a rear portion extending from the connecting portion to the other side (rightward in FIG. 2) orthogonal to the rotation shaft 23 is picked by a finger, thereby opening the grip portions 21b and 22b against the turning force. , 22c.

  As shown in FIG. 4, the coil spring 24 is inserted into the rotating shaft 23 and is provided between the pair of connecting pieces 22a, 22a of the plate-like member 22 as shown by broken lines in FIG. The portions extend obliquely toward the outside so as to open backward each other. One end 24a is in contact with the inner surface of the one plate-like member 21 on the side of the knob 21c, and the other end 24b is in contact with the inner surface of the other plate-like member 22 on the side of the knob 22c.

The gripping portions 21b and 22b of the two plate-like members 21 and 22 are curved so that the tip portions thereof are somewhat closer to each other, and the inner surfaces 21bi and 22bi have fine irregularities and a large number of shallow grooves along the width direction. It is desirable to form a rough surface by, for example, increasing the frictional force with the handle portion 11 of the toothbrush 10 and further ensuring its grip.
Further, when the same unevenness and grooves are formed on the outer surfaces 21co and 22co of the tabs 21c and 22c of the two plate-shaped members 21 and 22, the tabs 21c and 22c are gripped with fingers. When the spring-type clamper 2 is opened, it is desirable that the finger is difficult to slip and easy to operate.

  As a vibration source, the vibration motor 3 is arranged in parallel with the rotary shaft 23 so as to be somewhat inserted between the pair of connecting pieces 22a, 22a of the plate-like member 22 of the spring clamper 2. On the inner surface of the plate-like member 21, a support portion 21d extending in the width direction is integrally formed so as to fit the lower outer peripheral surface of the vibration motor 3, and the vibration motor 3 is waterproofly bonded to the support portion 21d. It is firmly fixed and supported integrally with the adhesive. On the inner surface of the plate-like member 22, a pressing portion 22d extending in the width direction is integrally formed with an inner surface shape that fits the upper outer peripheral surface of the vibration motor 3.

When the spring clamper 2 is in the free state shown in FIG. 2, the pressing portion 22d comes into contact with the upper surface of the vibration motor 3 by the rotational force of the plate-like members 21 and 22 by the coil spring 24, and the support portion 21d. The two plate-like members 21 and 22 are held substantially in parallel with the gripping portions 21b and 22b opened to some extent, with the vibration motor 3 sandwiched therebetween.
Therefore, the operation of attaching the handle portion 11c and 22c with the finger to open the gripping portions 21b and 22b and sandwiching the handle portion 11 of the toothbrush 10 with the gripping portions 21b and 22b as shown in FIGS. It can be done easily.

  As shown in FIG. 4, the vibration motor 3 has a cylindrical housing 3a in which a rotational drive unit 3b composed of a stator and a rotor is housed, and a fan-shaped eccentric weight 3d is fixed to the rotary shaft 3c. Therefore, when the rotary shaft 3c is rotated at a high speed by the rotation drive unit 3b, vibration is generated by the rotation of the eccentric weight 3d, and the entire housing 3a is vibrated, which is propagated to the entire spring clamper 2 through the support unit 21d. .

  When the vibration motor 3 is driven with the toothbrush 10 mounted as shown in FIGS. 1 and 3, the vibration is transmitted to the handle portion 11 of the toothbrush 10 through the grip portions 21 b and 22 b of the plate-like members 21 and 22. In addition to being propagated, the gripping portions 21b and 22b are pressed against the casing 3a of the vibration motor 3 so as to hold the handle portion 11 of the toothbrush 10 by the curvature thereof, so that the vibration motor 3 and the handle portion 11 are always in close contact with each other. The vibration is transmitted to the handle portion 11 without loss, and the toothbrush 10 can be vibrated extremely efficiently.

Therefore, an ordinary toothbrush can be used with performance equivalent to an expensive electric toothbrush, and tooth brushing can be performed easily and effectively.
In this embodiment, since the clamper side unit 1 and the power supply unit 4 are separated, the clamper side unit 1 that is a vibration unit can be reduced in size and weight, and the vibration of the vibration motor 3 can be efficiently transmitted to the toothbrush 10 and the operation of the toothbrush 10 can be performed. Is almost unobtrusive.

The two plate-like members 21 and 22 of the spring clamper 2 can be formed of various resins such as transparent, colored transparent, translucent, opaque, etc., with a stylish design that matches the toothbrush. Of course, you may form with a rustless light metal, such as stainless steel and aluminum.
Since the vibration motor 3 has a water proof (waterproof structure), the clamper side unit 1 can be kept clean by washing it with the toothbrush 10 or separately.

The power supply unit 4 is a rectangular column or columnar elongated small unit that houses a battery, and may be used in a pajamas, a shirt pocket, a trouser pocket, or the like. Alternatively, the clip piece 42 can be used by being fastened to clothes. Therefore, it is preferable to use a thin, flexible, color matching the spring-type clamper 2 for the power supply line 5, and a length of about 500 mm to 800 mm is appropriate.
FIG. 1 shows an example of the power supply unit 4 that uses one AA or AAA battery 43 that has good cost performance and can be made compact. However, it is a matter of course that a plurality of those batteries or single-type batteries may be used, or a rechargeable secondary battery or the like may be used.

  The switch 41 of the power supply unit 4 closes (turns on) the power feeding circuit when the push button 41a is pressed while the power feeding circuit to the vibration motor 3 is open (OFF), and in that state, the push button 41a is again pressed. An example of a push button type switch that opens (turns OFF) the power feeding circuit when is pressed is shown. However, other types of switches such as a slide type and a rotary type may be used.

  Further, although the switch is provided in the power supply unit 4, the switch may be provided in the clamper side unit 1, or the switch may be provided in both the power supply unit 4 and the clamper side unit 1. When the switch is provided in the clamper side unit 1, the power supply circuit to the vibration motor 3 is automatically opened and closed by mounting on the toothbrush 10 or according to the opening and closing of the spring clamper 2 as in the embodiment described later ( ON / OFF).

[Second Embodiment]

FIG. 5 is a plan view similar to FIG. 2 showing only the clamper side unit of the vibration unit for oral cleaning tool, and FIG. 6 is a longitudinal sectional view similar to FIG. 4 of the clamper side unit. In these drawings, portions corresponding to those in FIGS. 1 to 4 are denoted by the same reference numerals, and detailed description thereof is omitted. Also in the second embodiment, since the power supply unit and the feeder line are the same as those in the first embodiment, the illustration is omitted. However, in the second embodiment, the switch 41 of the power supply unit 4 used in the first embodiment may be omitted.

  In the clamper side unit 1 'of the second embodiment, a vibration motor is disposed at a position corresponding to a rotating shaft that rotatably connects the two plate-like members 21 and 22 constituting the spring clamper 2'. is doing. Therefore, as shown in FIG. 5, a hollow vibration motor holding portion 22e that also serves as a connecting piece is formed in the middle portion in the longitudinal direction of the plate-like member 22, and shaft portions 22f are projected from both end surfaces. . On the other hand, bearing grooves 21f are formed in the pair of connecting pieces 21a of the plate-like member 21 from the rear toward the center, and the shaft portions 22f of the plate-like member 22 can be inserted into the respective bearing grooves 21f from the rear.

  Plate spring locking portions 21g and 22g are formed on the inner surfaces of the tabs 21c and 22c of the plate-like members 21 and 22, respectively, and both end portions 25a and 25b of the plate spring 25 curved in a U-shape are plate-like members. 21 and 22 are engaged with the leaf spring engaging portions 21g and 22g, the intermediate portion 25c is pressed against the side surface of the vibration motor holding portion 22e, and the shaft portion 22f is not pulled out of the bearing groove 21f. Press on.

  As a result, the two plate-like members 21 and 22 are rotated around the shaft portion 22f that is a rotation shaft, as shown in FIG. 5, by the pair of connecting pieces 21a, the vibration motor holding portion 22e, and the pair of shaft portions 22f. Are connected to each other so that the gripping portions 21b and 22b are closed to each other.

The vibration motor 3 is disposed in the hollow portion of the vibration motor holding portion 22e of the plate-like member 22 so that the center thereof is at a concentric position corresponding to the pair of shaft portions 22f, and is adhered with a waterproof adhesive. And stick together. The configuration of the vibration motor 3 is the same as that of the first embodiment described with reference to FIG. The vibration motor holding part 22e does not need to cover the entire circumference of the casing 3a of the vibration motor 3, and may be provided in a range where the vibration motor 3 can be reliably held.
Further, in this embodiment, a push button type switch 26 is provided integrally with the housing 3a of the vibration motor 3, and at least the push button 26a is projected from the vibration motor holding portion 22e toward the gripping portions 21b and 22b. Yes.

  Then, the clamper side unit 1 'is gripped by the fingers 21c and 22c of the spring clamper 2', and the gripping portions 21b and 22b are opened against the rotational force of the leaf spring 25, as shown in FIG. When the toothbrush handle 11 is sandwiched between and attached to the toothbrush, the handle 11 is held on the switch 26 side by the bending of the gripping portions 21b and 22b. Thereby, the handle portion 11 presses the push button 26a, and the switch 26 is automatically operated so as to close the power feeding circuit from the power source portion to the vibration motor 3.

Therefore, when the clamper side unit 1 ′ is attached to the toothbrush, the vibration motor 3 is automatically activated to generate vibration, and the vibration is efficiently transmitted to the handle 11 through the plate-like members 21 and 22 and the switch 26. Thus, the toothbrush 10 can be vibrated extremely efficiently.
According to this embodiment, since the vibration motor 3 is disposed at a position corresponding to the rotation axis of the spring clamper 2 ', the clamper side unit 1' (vibration unit) can be further reduced in size and weight.

[Third embodiment]
Next, a third embodiment of the vibration unit for an oral cleaning tool according to the present invention will be described with reference to FIGS. FIG. 7 is a front view showing only the clamper side unit of the vibration unit for the oral cleaning tool, and FIG. 8 is a sectional view of only the main part in a state where the clamper side unit is mounted on the toothbrush. It is an enlarged view equivalent to the figure seen from the left side. Also in these drawings, the same reference numerals are given to portions corresponding to the respective portions in FIGS. 1 to 6.

  The clamper side unit 1 ″ of this embodiment is different from the first and second embodiments in that the gripping portions 21b and 22b of the two plate members 21 and 22 constituting the spring clamper 2 ″ (FIG. 7). The plate-like member 22 is overlapped on the other side of the plate-like member 21), and is formed so as to be elastically deformable to some extent and is divided into a plurality of portions in the direction along the longitudinal direction of the handle portion of the toothbrush to be sandwiched. It is. In the example shown in FIG. 7, each gripping part is divided substantially equally into five parts a to e by four cuts.

  In order to give elasticity to each part of a to e of the gripping portions 21b and 22b in the opening and closing direction, the plate-like members 21 and 22 may be formed of a slightly elastic resin or the like. Since the absorption to the handle 11 may be attenuated, the thickness of the gripping portions 21b and 22b may be reduced toward the tip.

In order to attach the clamper side unit 1 ″ to the toothbrush, when the handle portion 11 is sandwiched between the gripping portions 21b and 22b of the spring clamper 2 ″ as shown in FIG. 8, the gripping portions 21b and 22b are rotated in a direction to close each other. Since each of the portions a to e is individually brought into contact with the surface of the handle 11, it is closed. Therefore, as shown in FIG. 8, even if the handle portion 11 of the toothbrush has a curved surface whose thickness or thickness varies in the longitudinal direction, the portions a to e of the gripping portions 21b and 22b correspond to the curved surface. And can be sandwiched in close contact with the surface of the handle 11. That is, the compatibility with the shape of the handle is improved.
The configuration of the spring clamper 2 ″ and the holding structure of the vibration motor 3 in this embodiment may be the same as those in the first embodiment or the second embodiment.

[Other examples of power supply]
A description will be given of FIG. 9 showing another example of the power supply unit of the vibration unit for an oral cleaning tool according to the present invention. The power supply unit 40 shown in FIG. 9 is similar to a converter used as a power supply device for various small DC devices such as a small CD player and an information terminal device.
That is, the power supply unit 40 inserts a pair of plugs 40b protruding from the housing 40a into a commercial power outlet, takes in 100V AC, steps down with a transformer provided in the housing 40a, and rectifies and smoothes the circuit. Is converted to direct current of a predetermined voltage (for example, 1.5 V) and supplied to the vibration motor 3 of the clamper side unit through the feeder line 5. It is convenient to provide a power plug 6 at the end of the power supply line 5 so that the power supply unit 40 can be inserted and removed.

[Fourth embodiment]
Next, a fourth embodiment of the vibration unit for an oral cleaning tool according to the present invention will be described with reference to FIG. FIG. 10 is a front view similar to FIG. 1, showing the oral cleaning tool vibration unit mounted on a toothbrush. 10, parts corresponding to those in FIG. 1 are denoted by the same reference numerals.

  The oral cleaning tool vibration unit 7 shown in FIG. 10 has a spring-type clamper 2 and a vibration motor 3 that is a vibration source that generates vibration by power feeding and a power supply unit 8 that feeds the vibration motor 3 integrally. It is fixed. That is, the battery case that houses the battery 81 that constitutes the power supply unit 8 is attached to the two plate-like members 21 and 22 (the plate-like member 22 is behind the plate-like member 21) that constitutes the spring clamper 2. It is integrally formed with resin or the like. In the example shown in FIG. 10, it is formed integrally with the plate member 22 on the rear side.

  When the spring clamper 2 is mounted on the toothbrush 10 with the handle 11 attached to the power supply unit 8 integrated with the spring clamper 2, the handle 11 closes the power supply circuit to the vibration motor 3. A switch 82 is arranged at a position where the push button 82a is pushed and operated. In this manner, when the oral cleaning tool vibration unit 7 is attached to the toothbrush 10, the vibration motor 3 is automatically activated to generate vibrations and vibrate the toothbrush, so that toothbrushing can be started immediately. it can.

  It is necessary to make the power supply unit 8 as small as possible so that the handle portion 11 of the toothbrush 10 does not become difficult to grip. Therefore, if an ultra-small battery such as a button battery is used as the battery, the power supply unit 8 can be hardly protruded from the spring clamper 2. However, considering power capacity and cost performance, it is better to use AAA batteries. Even in such a case, if the power supply unit 8 is thinned as shown in the figure and arranged so as to be close to the handle part 11 of the toothbrush 10, the handle part 11 and the power supply part 8 can be held together to brush the teeth.

The configuration of the spring clamper 2 and the holding structure of the vibration motor 3 in this embodiment may be the same as those in the first embodiment or the second embodiment. In order to reduce the size, the second embodiment should be used. Further, if a switch is provided on the vibration motor 3 side, the switch 82 of the power supply unit 8 becomes unnecessary.
Further, as in the third embodiment shown in FIG. 7, the gripping portions 21b and 22b of the spring clamper 2 are made elastically deformable to some extent, and a plurality of portions are arranged in the direction along the longitudinal direction of the handle portion 11 of the toothbrush 10 to be sandwiched. You may divide and form.

[Other examples of oral cleaning tools]
In each Example mentioned above, the example in the case of using a toothbrush as an oral cavity cleaning tool was demonstrated. However, the oral cleaning tool is not limited to this, and the oral cleaning tool vibration unit according to the present invention can be mounted on an interdental brush or a tongue cleaner.

  The interdental brush is a small cylindrical brush in which the tip of the handle portion has a tapered shape, and a number of short resin hairs are held radially over the length of about 1 cm by a twisted thin wire. The portion extends in the axial direction and is fixed. The wire of the brush part has elasticity and can bend freely. Further, the length of the resin bristles becomes shorter as it goes to the tip, and the brush diameter becomes smaller, so that the brush part easily enters a gap between teeth.

  Such interdental brushes generally have many handle portions that are thinner and shorter than toothbrushes, but there are also interdental brushes having handle portions equivalent to toothbrushes. For such an interdental brush, the vibration unit for the oral cleaning tool of each embodiment described above is attached to the interdental brush instead of the toothbrush, and it is slightly vibrated to clean the teeth and massage the gums. Can be done well.

  There is also a tongue cleaner as another oral cleaning tool. This tongue cleaner is provided with an inverted triangular frame type head at the tip of the handle, and a large number of resin hairs on one side of the side corresponding to the bottom of the frame type head are 20-30. A brush part for removing tongue coating on the surface of the tongue is formed by bundling each other in multiple rows.

  In many cases, the handle portion of the tongue cleaner has the same length and thickness as the handle portion of the toothbrush. Therefore, if the vibration unit for an oral cleaning tool according to the present invention is used while being mounted on the handle, vibrations from the vibration motor are transmitted to the head through the handle of the tongue cleaner, causing the brush to slightly vibrate. By placing the resin bristles of the brush portion on the tongue surface and gently stroking it, the tongue coating between the tongue papillae can be easily removed without damaging the small protrusions of the tongue papillae on the tongue surface.

  In addition, the oral cleaning tool vibration unit according to the present invention can be used with various oral cleaning tools having a handle. Further, the size and shape of the gripper side unit, in particular the gripping portion, can be changed according to the size and shape of the handle portion of the oral cleaning tool to be used.

  Also, although it is not an oral cleaning tool, a beautiful facial magnet roller that massages the face's eyes, corners, cheeks, or the entire face with a magnetic roller can also be used by attaching a vibration unit for an oral cleaning device according to the present invention to the handle. A desired part of the face can be massaged while giving a slight vibration to the roller. Thereby, the blood flow of the face is promoted, and the facial effect is enhanced.

[Other examples of vibration sources]
In each of the above-described embodiments, the example in which the vibration motor is used as the vibration source has been described. However, the present invention is not limited to this. For example, any vibration generating device that can be miniaturized, such as an ultrasonic vibrator, a piezoelectric vibrator, and an electromagnetic vibrator, can be used.
