Description

The present invention relates to an oral cleaning tool comprising an illuminated vibrator for oral cleaning tool and an oral cleaning brush head .

As an oral cleaning tool, a toothbrush that brushes teeth to prevent tooth decay has been used for many years. In addition, interdental brushes have been used for a long time to prevent periodontal disease by removing food waste and plaque clogged between the teeth.
Furthermore, in recent years, electric toothbrushes and electric interdental brushes that incorporate a vibration motor, an ultrasonic vibrator, and the like to vibrate the brush have been used.

  For example, in Patent Document 1, a vibration motor and a battery in which an eccentric rotating body is attached to a rotating shaft are incorporated in a case, and an attachment provided with a curved flocking portion is detachably attached to one end of the case. An electric toothbrush is disclosed. In this electric toothbrush, the vibration generated by the rotation of the vibration motor is transmitted to the attachment through the case to vibrate the flocked portion.

Further, in Patent Document 2, an interdental brush having fine hairs is detachably attached to the tip of a gripping part incorporating an ultrasonic vibrator, and ultrasonic vibrations are transmitted to the fine hairs to clean between the teeth. An electric interdental brush is disclosed.
If such an electric toothbrush or an electric interdental brush is used, the flocked part will vibrate automatically, so even if you do not move your hands consciously, dirt on the teeth and between teeth, food waste, plaque Thus, it is possible to easily and efficiently remove the plaque).

Furthermore, Patent Document 3 discloses a light-transmitting member such as an optical fiber for housing a battery and a vibration motor in a toothbrush body, providing a light source inside or outside the toothbrush body, and guiding light from the light source to the flocked portion. Is transmitted through the toothbrush body and the head portion including the hair transplantation portion, and the vibration of the vibration motor is transmitted to the hair transplantation portion of the head portion. An optical toothbrush adapted to irradiate is disclosed.
According to this light toothbrush, tooth brushing can be easily performed by vibration of the flocked portion, and by irradiating light in the oral cavity, it can be sterilized or antibacterial, prevention of dental caries , tooth bleaching, or gingival activation, etc. It is described that comprehensive dental care can be performed.

  Furthermore, in Patent Document 4, a light emitting diode (LED) as a light source is provided in the movable bristle holder of the head portion of the electric toothbrush, and the movable bristle holder is imparted with motion such as rotation and vibration. There is disclosed an illuminated electric toothbrush that irradiates the oral cavity with light from lighting of the provided LED.

Japanese Patent Laid-Open No. 2001-178752 JP 2003-1111779 A JP 2005-348799 A JP 2009-213908 A

However, the electric toothbrush and the electric interdental brush disclosed in Patent Document 1 or 2 do not irradiate light into the oral cavity, so that effects such as sterilization, antibacterial action, and bleaching cannot be obtained.
On the other hand, according to the optical toothbrush or the electric toothbrush with illumination disclosed in Patent Document 3 or 4, toothbrushing action by movement such as vibration of the hair transplantation part of the head part or the movable bristle holder, and sterilization by light irradiation in the oral cavity And antibacterial and bleaching effects can be expected.

  However, since the optical toothbrush described in Patent Document 3 guides light from the light source to the flocked portion by a light transmissive member such as an optical fiber provided in the toothbrush main body and through the head portion, the light toothbrush includes a toothbrush main body and a flocked portion. When the head part is integrally formed and a light transmissive member is provided in the head part or the head part can be attached to and detached from the toothbrush body, a light transmissive member is incorporated in the toothbrush body and the head part, respectively. In addition, it is necessary to optically connect the light transmissive members of the toothbrush main body and the inside of the head portion.

  The electric toothbrush with illumination described in Patent Document 4 must also be provided with wiring from the handle (main body part) incorporating the power source to the LED provided on the movable bristle holder of the head part. When wiring the inside or making the head part detachable from the handle (main body part), the wiring is provided in the handle and the head part, and the wiring between the two at the connection part between the handle and the head part. Need to be electrically connected.

  When the toothbrush main body (the handle of Patent Document 4 corresponds to this) and the head part are formed integrally, the toothbrush main body provided with a power source and a drive source such as a vibration motor has various toothbrushes and interdental brushes. The head part (attachment) of the oral cleaning tool cannot be selectively worn and used, and multiple users such as family members have only the head part and share the toothbrush body In addition, it is extremely uneconomical that the entire device cannot be used when the flocked portion is consumed.

  If the toothbrush body and the head part are separated and made detachable, the above-mentioned problems can be solved, but the structure of the toothbrush is not only complicated, but the consumable head part is formed in the cavity. In addition, a light-transmitting member such as an optical fiber or wiring is passed through it, and the light-transmitting member or wiring in the toothbrush main body must be optically connected or electrically connected. .

In the case of the optical toothbrush of patent document 3, there also exists a problem that a light quantity loss generate | occur | produces in a light transmissive member or an optical connection part.
Moreover, in the case of the electric toothbrush with illumination of patent document 4, when the hair of a head part is consumed and replaced | exchanged, since LED which is a light source will also be discarded, it is very uneconomical. Furthermore, since the LED is provided on the hair holder that is inserted into the oral cavity with saliva and used for attaching a dentifrice or washing with water, there is a problem in terms of insulation and durability.

  The present invention has been made to solve the above problems, and can be used by selectively mounting various oral cleaning brush heads (attachments) such as toothbrushes and interdental brushes, and is simple and inexpensive. A vibrator with an illumination for oral cleaning tools, which transmits vibration to the installed brush head for oral cleaning and allows light to enter the oral cavity when brushing teeth, and so on.

Hereinafter, embodiments for carrying out the present invention will be specifically described with reference to the drawings.
[First embodiment]
FIG. 1 is a cross-sectional view showing a first embodiment of an oral cleaning tool according to the present invention in which a toothbrush head is mounted on an illuminated vibrator for an oral cleaning tool.

  The illuminated vibrator 1 for an oral cleaning tool shown in FIG. 1 has a cylindrical housing 10 suitable for grasping by hand, one end of which is formed in a tapered cone shape, and an oral cleaning brush head ( In this embodiment, it has a fitting support portion 11 for fitting and supporting the fitting portion 21a of the handle portion 21 of the toothbrush head 2). The housing 10 can be formed of a light metal such as aluminum or a synthetic resin into a cylindrical shape, a rectangular tube shape, or any other shape suitable for holding with a hand. Although the housing 10 and the fitting support portion 11 can be formed integrally, they may be formed of another material and fixed together.

  In the housing 10, a power source 12, a vibration motor 13, and a booster circuit 14 are provided, and a light source 15 is disposed in the fitting support portion 11 toward the opening. In addition, a power switch 16 is provided at a position where it can be operated from the outside of the housing 10, and when the power switch 16 is turned on, the power is supplied from the power source 12 to the vibration motor 13 and the vibration motor 13 is operated to vibrate the housing 10. The vibration is transmitted to the toothbrush head 2 which is a brush head for an oral cleaning tool fitted and supported by the fitting support portion 11 to vibrate the brush portion 22.

At the same time, a voltage boosted to a voltage suitable for the light source 15 by the booster circuit 14 is applied to the light source 15, whereby the light source 15 emits light and the handle portion 21 of the toothbrush head 2 fitted and supported by the fitting support portion 11. Light is incident inside.
Although not shown, the casing 10 is provided with a battery holder for storing a battery as a power source 12 and an opening / closing part for replacing the battery.
An illuminated electric toothbrush as an oral cleaning tool is configured by the illuminated vibrator 1 for oral cleaning tool and the toothbrush head 2 shown in FIG.

The toothbrush head 2, which is a brush head for oral cleaning in this embodiment, has a large number of resin bristles 23 at the distal end portion 21 b of the handle portion 21 whose base portion is a fitting portion 21 a that can be fitted to the fitting support portion 11. Is provided with a brush portion 22 implanted in a bundle of about 10 to 20 pieces, and both the handle portion 21 and the resin bristles 23 of the brush portion 22 are all or most of the transparent resin having good light transmittance. Etc.
Examples of the transparent resin include acrylic resin, epoxy resin, saturated polyester resin, methacrylic resin, fluorene-based transparent resin, styrene-based transparent resin, transparent ABS resin, and polypropylene resin for the handle portion 21, and polyester or nylon for the resin hair 23. For example, various transparent resin materials can be used.

  In addition, you may form the film which reflects inside without leaking outside on the outer peripheral surface of the handle | pattern part 21 of the toothbrush head 2, and the back side of the brush part 22 in the front-end | tip part 21b. However, even if the entire handle portion 21 is transparent, the light incident from the base end face can be sufficiently practically guided to the brush portion 22.

  Further, as shown in FIG. 1, the back side of the brush portion 22 of the tip portion 21b of the handle portion 21 is formed so as to be inclined or curved so as to approach the resin hair 23 as it goes forward. The light reaching the back surface can be easily reflected toward the resin hair 23. If a reflective film is formed on the back side of the brush portion 22 of the tip portion 21b, the effect can be further enhanced.

  Therefore, the light incident on the handle portion 21 of the toothbrush head 2 fitted and supported by the light emission of the light source 15 disposed in the fitting support portion 11 of the vibrator with illumination 1 for an oral cleaning tool is transparent. The handle portion 21 is guided to the brush portion 22 as a light guide, and the teeth to be polished with the resin hair 23 of the brush portion 22 in the oral cavity and its surroundings are irradiated through the transparent resin hair 23. Further, when brushing teeth, almost the entire brush portion 22 is inserted into the oral cavity, so that light emitted from the entire brush portion 22 illuminates the oral cavity.

By the light irradiation, it is possible to obtain comprehensive dental care effects such as sterilization or antibacterial in the oral cavity, prevention of dental caries , bleaching of teeth or activation of gums.
The vibration motor 13 is an extremely small motor having an eccentric mass body attached to a rotating shaft, vibrates the entire housing 10, and the vibration 21 is fitted to and supported by the fitting support portion 11. Is transmitted to the brush part 22 and the brush part 22 is vibrated slightly with a frequency of 120 to 150 Hz and an amplitude of 0.1 to 0.5 mm, for example. Thereby, dirt on the teeth, plaque and the like can be efficiently removed. If the vibrating brush part 22 is applied to the gums, blood flow is promoted by the massage effect, and a strong gum can be formed.

  In this embodiment, the fitting support portion 11 is a cylindrical concave portion having flexibility in the radial direction, and the light source 15 is disposed at the bottom of the cylindrical concave portion. The cylindrical recess is preferably formed in a cylindrical shape with a metal or resin having elasticity, and a plurality of slots are provided at equal angular intervals in the radial direction. Furthermore, it is preferable to provide an urging member such as an elastic ring that urges the cylindrical recess to reduce its diameter and increase the force for clamping the handle portion 21 of the inserted toothbrush head 2. Further, it is preferable that the insertion amount of the handle portion 21 of the toothbrush head 2 is regulated so that a locking projection 21 c is provided on the outer peripheral surface of the handle portion 21 so that the base end surface of the handle portion 21 does not collide with the light source 15.

If the fitting support part 11 is configured in this way, the handle part 21 of the toothbrush head 2 may be a simple rod, so that it is easy to mold and durable, and can be made inexpensive and compact. Moreover, even if there is some variation in the thickness of the handle portion 21 of the toothbrush head 2, it can be absorbed and supported so that it becomes a universal joint, and even a commercially available brush head has at least a handle. If the part is transparent, it can be used.
Further, since the light source 15 is disposed at the bottom of the cylindrical recess, the light is not leaked, and is guided to the base end surface of the handle 21 of the toothbrush head 2 fitted therein, and all the handle 21 is incident. Therefore, the light use efficiency is high.

FIG. 2 is a circuit diagram of the first embodiment. This circuit constitutes a power feeding circuit from the power source 12 to the vibration motor 13 via the power switch 16, and further constitutes a power feeding circuit to the light source 15 via the booster circuit 14.
As the power source 12, for example, a DC 1.5V AAA battery is used, but a button-type battery or a rechargeable secondary battery may be used. The booster circuit 14 is provided for boosting the voltage of the power source 12 to a rated voltage (for example, 3 V) at the time of light emission of a light emitting diode (LED) that is the light source 15, and the rated voltage at the time of light emission of the light source 15 is the output voltage of the power source. It is not necessary to provide it if

  The light source 15 is preferable because the LED is small and relatively inexpensive, and can easily emit light of a desired wavelength. However, a small lamp or a semiconductor laser light source may be used. The spectrum of light emitted from the light source is not particularly limited, and not only visible light but also light of any wavelength including ultraviolet rays and infrared rays can be used. The effect of dental care varies depending on the wavelength range.

In this embodiment, a red LED which is a light source that emits red light (wavelength: 610 to 750 nm) is used as the light source 15. As a result, it has been clarified as a result of the experiment that the gum can be irradiated with red light and is particularly effective in preventing the generation of periodontal disease bacteria. The red light is optimally center wavelength: about 625 nm and illuminance: about 380 mcd.
However, the light source 15 is not limited to the red LED, and an LED or white LED that emits light of other colors such as blue, green, and yellow, or a small lamp or semiconductor laser light source as described above, depending on the purpose of light irradiation. Etc. may be used. In addition to a visible light region, a light source that emits ultraviolet light or infrared light may be used.

[Second Embodiment]
Next explained is the second embodiment of the invention. FIG. 3 is a cross-sectional view similar to FIG. 1 of the oral cleaning tool equipped with an illumination vibrator and a toothbrush head of the second embodiment, and FIG. 4 is a circuit diagram similar to FIG. In these drawings, portions corresponding to those in FIGS. 1 and 2 are denoted by the same reference numerals, and description thereof is omitted.

  The second embodiment is different from the first embodiment described above in that red light (wavelength: 610 to 750 nm) and blue light (wavelength) are used as the light source 15 'of the vibrator 1' with the oral cleaning tool illumination shown in FIG. : 435 to 480 nm) for switching the emission color of the two-color light emitting diode that is a two-color light source to a position that can be operated from the outside of the housing 10. The only difference is that a color switching switch 17 is provided.

  In the two-color light emitting diode, a red light emitting element 15R that emits red light and a blue light emitting element 15B that emits blue light are arranged adjacent to each other in one capsule. Then, when the movable contact m of the color switching switch 17 shown in FIG. 4 is in a position where it is connected to the fixed contact a, only the red light emitting element 15R is energized, so that red light is emitted. When the movable contact m of the color switching switch 17 is switched to a position where it is connected to the fixed contact b, only the blue light emitting element 15B is energized, and therefore blue light is emitted.

Experimental results have revealed that irradiating the surface of the tongue with blue light has the effect of suppressing the occurrence of tongue lichens that cause bad breath. The blue light is optimally center wavelength: about 467 nm and illuminance: about 700 mcd.
When the movable contact m of the color switching switch 17 shown in FIG. 4 is connected to the fixed contact c, neither the red light emitting element 15R nor the blue light emitting element 15B of the light source 15 ′, which is a two-color light emitting diode, is energized. Since the two-color light emitting diode does not emit light, it is not irradiated with light and only the vibration of the brush head occurs, but it can be used in the same manner as a conventional electric toothbrush.

The light source 15 ', which is a two-color light emitting diode, may always emit red or blue light while the power switch 16 is ON without providing the position of the fixed contact c.
Alternatively, as shown in FIG. 5, a diode D1 is connected between the fixed contact c and the fixed contact a of the color switching switch 17 so as to be in the forward direction from the fixed contact c to the fixed contact c. A diode D2 may be connected to b from the fixed contact c to b in the forward direction.

  In this way, when the movable contact m of the color changeover switch 17 in FIG. 5 is in a position where it is connected to the fixed contact a or b, the red light emitting element 15R or the blue light emitting element of the light source 15 'which is a two-color light emitting diode. Only one of 15B is energized, the energization to the other is blocked by the diode D1 or D2, and the two-color light emitting diode emits red light or blue light as in the case of the circuit shown in FIG.

When the movable contact m of the color switching switch 17 is switched to the position where it is connected to the fixed contact c, both the red light emitting element 15R and the blue light emitting element 15B are energized via the diode D1 or D2, so that the two color light emitting diode is used. A certain light source 15 ′ emits light with mixed light (magenta color) of red light and blue light.
If used in this state, both the effect of preventing the generation of periodontal disease bacteria by red light and the effect of suppressing the generation of tongue coating by blue light can be obtained.
Since the toothbrush head 2 can be illuminated with various colors, the color change can be enjoyed.

[Third embodiment]
Next, a third embodiment of the present invention will be described. FIG. 6 is a cross-sectional view similar to FIG. 3 of the oral cavity cleaning tool of the third embodiment and an oral cleaning tool equipped with a toothbrush head, and the parts corresponding to those in FIGS. 1 and 3 are the same. The description is omitted.

  The casing 10 'of the vibrator 1 "for oral cleaning tool illumination shown in FIG. 6 of the third embodiment has a handle 21 of the brush head for oral cleaning tool (toothbrush head 2' in this embodiment) at the tip. ′ Has a taper fitting support portion 11 ′ which fits and supports the outer side of the toothbrush head 2 ′. A recessed fitting portion 21d is provided.In the fitting support portion 11 'of the housing 10' in the illuminated vibrator 1 "for oral cleaning tool, a light source 15 'is provided at the opening near the tip. It is arranged toward.

The fitting position between the fitting portion 21d of the handle portion 21 'of the toothbrush head 2' and the fitting support portion 11 'of the housing 10' is such that the recess inner end surface 21e of the fitting portion 21d and the fitting support portion 11 '. Although it is regulated by contact with the tip, a click unevenness for retaining may be provided between them, or a simple bayonet or screw structure may be provided.
In a state where the fitting portion 21d of the handle portion 21 'of the toothbrush head 2' is fitted and supported by the fitting support portion 11 'of the housing 10', the light emitting portion of the light source 15 'is fitted to the handle portion 21'. It is close to the inner surface 21e of the recess formed in the portion 21d, and light can be efficiently incident from there into the transparent handle portion 21 '.

  In FIG. 6, a color changeover switch 17 is provided, and an example in which a two-color light emitting diode is used as the light source 15 'is shown, as in the second embodiment described with reference to FIGS. However, the color changeover switch 17 is omitted, and a single color LED or white LED that emits red light or the like, or another light source is used as the light source, as in the first embodiment described with reference to FIGS. Of course, it may be.

[Other examples of brush head for oral cleaning]
Each Example mentioned above demonstrated the example which uses the toothbrush head provided with the brush part for cleaning the surface of a tooth | gear at the front-end | tip part of a handle | pattern part as a brush head for oral cavity cleaning. However, the brush head for oral cleaning is not limited to this.

  FIG. 7 is a side view showing an example of an interdental brush head which is another example of the oral cavity cleaning brush head. In this interdental brush head 3, at least the base fitting portion 31 a of the columnar or polygonal columnar handle 31 is fitted to the illuminated vibrator 1 or 1 ′ for the oral cleaning tool of the first or second embodiment. The tip portion 31b of the handle portion 31 has a tapered shape and is supported by being fitted into the support portion 11, and a plurality of short resin hairs 32b are 1 cm by a thin twisted wire 32a at the tip end. A small cylindrical brush portion 32 held radially over a certain length extends in the axial direction and is fixed.

The wire 32a of the brush portion 32 has elasticity and can be bent freely. Further, the length of the resin bristles 32b becomes shorter as it goes to the tip, and the brush diameter becomes smaller, so that the brush part 32 can easily enter the gap between the teeth.
The handle portion 31 of the interdental brush head 3 and the resin bristles 32b of the brush portion 32 are all formed of a transparent resin as in the above-described toothbrush head.

  If this interdental brush head 3 is used by being inserted into and supported by the fitting support portion 11 of the vibrator 1 or 1 ′ with illumination for the oral cleaning tool of the first or second embodiment, the housing by the vibration motor 13 is used. 10 vibrations are transmitted to the interdental brush head 3 to slightly vibrate the brush portion 32 at the tip thereof. Therefore, just trace the tip of the brush part 32 along the gums, and if there is a gap between the teeth, the brush part 32 will vibrate and enter there, making it easy to remove clogged food and plaque. In addition to being removed, the gums are massaged at the same time, and blood flow is promoted to prevent periodontal disease.

Furthermore, the light emitted from the light source 15 or 15 'provided on the fitting support 11 of the illuminated vibrator 1 or 1' for the oral cleaning tool is incident on the transparent handle 31 of the interdental brush head 3, It is guided to the brush part 32 using the handle part 31 as a light guide, and irradiates between teeth in the oral cavity and surrounding teeth and gums through the transparent resin hair 32b. In many cases, the tip 31b of the handle 31 also enters the oral cavity. In that case, light emitted from the tip 31b directly illuminates the oral cavity.
By the light irradiation, it is possible to obtain comprehensive dental care effects such as sterilization or antibacterial in the oral cavity, prevention of dental caries , bleaching of teeth or activation of gums. In particular, when red light is irradiated on gums or the like, there is an effect of suppressing the generation of periodontal disease bacteria.

  When the interdental brush head is fitted and supported by the fitting support portion 11 'of the illuminated vibrator 1 "for the oral cleaning tool of the third embodiment, the base portion of the handle portion 31 is slightly thickened. Thus, a fitting part similar to the fitting part 21d of the toothbrush head 2 'shown in FIG. 6 may be formed.

FIG. 8 is a plan view showing an example of a tongue cleaner head which is still another example of the oral cleaning brush head. The tongue cleaner head 5 is provided at the base of the handle 51 extending linearly from one vertex of the triangular frame 51b of the illuminated vibrator 1 or 1 'for the oral cleaning tool of the first and second embodiments. A fitting portion 51a having a shape and a size to be fitted and supported in the fitting support portion 11 is provided, and a large number of resin hairs 53 are provided on one surface of the side corresponding to the base of the triangle at the tip of the frame-like portion 51b. A brush part 52 for removing tongue coating on the surface of the tongue is configured by being bundled in a row of -30 pieces.
The handle portion 51 including the frame-like portion 51b of the tongue cleaner head 5 and the resin bristles 53 of the brush portion 52 are all formed of a transparent resin as in the case of the toothbrush head 2 described above.

  If this tongue cleaner head 5 is used by being fitted to and supported by the fitting support portion 11 of the vibrator 1 or 1 ′ with illumination for an oral cleaning tool of the first or second embodiment, the casing 10 by the vibration motor 13 is used. Is transmitted to the tongue cleaner head 5 to slightly vibrate the brush portion 52 at the tip thereof. Therefore, by placing the resin hair 53 of the brush portion 52 on the tongue surface and gently stroking it, the tongue coating between the tongue papillae can be removed without damaging the small protrusions of the tongue papillae on the tongue surface.

  Furthermore, the light emitted from the light source 15 or 15 'provided on the fitting support 11 of the illuminated vibrator 1 or 1' for the oral cleaning tool is incident on the transparent handle 51 of the tongue cleaner head 5, However, the handle 51 is guided to the brush 52 using the light guide as a light guide, and the tongue surface in the oral cavity is irradiated through the transparent resin hair 53. Moreover, since the frame-shaped part 51b of the handle | pattern part 51 also enters in an oral cavity in that case, the light radiated | emitted here illuminates the oral cavity directly.

By the light irradiation, comprehensive dental care effects such as sterilization or antibacterial in the oral cavity, prevention of dental caries , bleaching of teeth or activation of gums can be obtained. In particular, using the illuminated vibrator 1 'for the oral cleaning tool of the second embodiment and causing the light source 15' to emit blue light and irradiating it with the tongue surface has the effect of suppressing the generation of tongue lichens. .

  When the tongue cleaner head 5 is fitted and supported by the fitting support portion 11 ′ of the vibrator 1 ′ with illumination for a mouth cleaning tool of the third embodiment, the base portion of the handle portion 51 is shown in FIG.
