It is said to have excellent effects.

Japanese Patent Publication No. 48-27390

  However, during actual brushing, saliva in the oral cavity is mixed into the agent, and at the same time, the agent component hardly acts on the stain due to the mixing of air by brushing. Further, since the agent diffuses in the oral cavity, the agent component hardly acts on the stain.

  And the brush part must be moved manually, and there is a limit to the speed at which the brush can be moved manually.

  This invention is invented in view of the said background art, The subject is providing the tooth cleaning apparatus which raises the stain removal effect adhering to the small clearance gap between teeth and a tooth | gear.

  In order to solve the above problems, in the invention according to claim 1 of the present application, in a tooth cleaning apparatus including a gripping part and a cleaning operation part for cleaning teeth, the gripping part is connected to one electrode of an internal power source. The cleaning operation unit side electrode is connected to the other electrode of the internal power supply, and the toothpaste is held at the tip of the cleaning operation unit side electrode. The tooth cleaning device is characterized by having an agent holding part.

  The invention according to claim 2 of the present application is characterized in that in the tooth cleaning device according to claim 1, the device has an outer frame portion surrounding the agent holding portion, and the outer frame portion is made of an electrically insulating material.

  Further, in the invention according to claim 3 of the present application, in the tooth cleaning device according to claim 1 or 2, the illuminating device for lighting and displaying the energization between the gripping portion side electrode and the cleaning operation portion side electrode is provided in the cleaning operation portion. It is characterized by having in the vicinity.

  Further, in the invention according to claim 4 of the present application, in the tooth cleaning device according to any one of claims 1 to 3, the attachment part provided with the cleaning operation part and the main body part provided with the grip part are divided.

  In the tooth cleaning apparatus according to the first aspect of the present invention, the cleaning effect in the oral cavity is enhanced by energizing the gap between the gripping portion side electrode and the cleaning operation portion side electrode. Moreover, by disposing the dentifrice in the agent holding part, it is possible to prevent the dentifrice from being dispersed in the oral cavity.

  Further, by brushing the teeth in the cleaning operation unit in a state where the stain removal effect is enhanced by energization, fine movement is possible faster than the conventional manual operation, and the cleaning effect is enhanced. Stain removal can be easily done even by children and the elderly who have little polishing power.

  Further, since the teeth are closer to the cleaning operation unit side electrode than the conventional one, it becomes easier to energize.

  A dentifrice containing a substance that is decomposed by electricity and becomes a charged molecule effective for stain removal as a dentifrice with a stain removal effect when the gripping part side electrode is a positive electrode and the cleaning operation part side electrode is a negative electrode In the state where the agent holding part is filled, the current flows between the gripping part side electrode and the cleaning operation part side electrode from the gripping hand through the body and finally the teeth, It flows to the cleaning operation part side electrode through the dentifrice of the agent holding part. Charged molecules having a negative charge are attracted to the teeth on the positive electrode side, and the concentration of charged molecules near the teeth increases. By increasing the number of charged molecules acting on the stain attached to the teeth, a chemical reaction having a stain peeling effect is promoted, and as a result, the stain removal effect is enhanced.

  Further, by arranging the dentifrice in the agent holding part provided at the tip of the cleaning operation part, it becomes possible to efficiently move the charged molecules by intensively flowing the current and to remove the stain intensively. . Further, since the agent holding part can release the dentifrice while holding it, the tooth can be brushed while passing an electric current through the dentifrice, and the stain removal effect is enhanced.

  Furthermore, the electrode on the tooth side becomes a positive electrode and the electrode on the cleaning operation unit side becomes a negative electrode, so that stains (colored dirt substances, spears, tea astringents, etc.) contained in the saliva and water in the oral cavity are cleaned operation unit side electrode It is effective to increase the stain removal effect.

  Even when the dentifrice is other than a charged molecule compounding agent, the above-mentioned tooth side electrode becomes a positive electrode, and the cleaning operation part side electrode becomes a negative electrode, so that stains contained in saliva or water in the oral cavity are included. The effect of being effective in attracting (stained stains, stains, tea astringents, etc.) to the cleaning operation part side electrode and enhancing the stain removal effect is obtained.

  In addition, when the gripping part side electrode is a negative pole and the cleaning operation part side electrode is a positive pole, the current flows in the opposite direction. In this case, if the cleaning operation part side electrode contains a material effective for the oral cavity such as silver, it melts and an effective effect is produced.

  In the tooth cleaning device according to the second aspect of the present invention, in particular, the outer frame portion is made of an electrically insulating material to prevent direct contact between the cleaning operation portion side electrode and the oral cavity, thereby ensuring the safety of the user.

  In the tooth cleaning device according to the third aspect of the present invention, the cleaning operation unit can be brought into contact with the teeth in an appropriate state in the oral cavity, particularly by illuminating the oral cavity with the lighting device. By increasing the contact ratio between the cleaning operation unit and the teeth, the stain removal effect can be maintained. Furthermore, since the energized state can be constantly confirmed, it is possible to avoid the non-energized state and maintain the stain removal effect.

  Moreover, in the tooth cleaning apparatus according to the fourth aspect of the present invention, the attachment part and the main body part can be divided, thereby being compact and easy to carry. In addition, a water intrusion member is provided between the attachment part and the main body part to prevent the ingress of water, thereby preventing deterioration of the equipment in the apparatus and extending the life of the apparatus.

There is a reciprocating drive joint 21 connecting the two.

  The internal power supply 4, the circuit 17, and the gripping part side electrode 5 are connected by wiring and form a conduction path. Further, the internal power supply 4, the circuit 17, and the motor 15 for driving the circuit motion are also connected by wiring to form a conduction path.

  The motion converter 18, the reciprocating drive 19, and the reciprocating drive joint 21 are made of a metal material. An example of the motion converter 18 is a bearing. The gripping part side electrode 5 is made of a metal plate. The gripper side electrode 5 may be another member as long as it is conductive.

  As shown in FIG. 4, the attachment unit 10 includes a slide shaft 20, a spring 22, a turntable 6, a turntable center shaft 23 that supports rotation of the turntable 6, and an eccentric position of the turntable 6. An eccentric shaft 24 that is an axis connecting the slide shaft 20, a connecting piece 25 connecting the slide shaft 20 and the eccentric shaft 24, an agent holding portion 7, and an outer frame portion 8 surrounding the agent holding portion 7. The cleaning operation unit 2 at the tip of the attachment unit 10 includes the above-described agent holding unit 7, outer frame unit 8, and turntable 6.

  The slide shaft 20 is housed in the attachment portion 10 with a slight gap between the slide shaft 20 and the inner surface of the attachment portion 10, and one end in the axial direction of the slide shaft 20 connects the reciprocating drive joint portion 21 of the main body portion 11. It connects with the reciprocating drive body 19 via. The other end of the slide shaft 20 in the axial direction is attached to a connecting piece 25 that is a connecting portion with the eccentric shaft 24 of the turntable 6. The reciprocating drive joint portion 21 of the slide shaft 20 is provided with a spring 22 that applies a spring force toward the reciprocating drive body 19 in the axial direction of the attachment portion 10, and the slide shaft 20 rattles by the spring 22. Prevents abnormal noise.

  The turntable 6 which is a part of the cleaning operation unit 2 also serves as the cleaning operation unit side electrode 6. Therefore, the turntable 6 is made of a conductive metal. In addition, even if it is not a metal, what is necessary is just a conductive thing.

  The agent holding unit 7 which is a part of the cleaning operation unit 2 is installed in front of the turntable central shaft 23 in the axial direction in order to efficiently pass a current to the dentifrice. Moreover, the agent holding | maintenance part 7 is opened to the front so that dentifrice can be discharge | released.

  The outer frame portion 8 which is a part of the cleaning operation unit 2 is provided so as to surround the agent holding unit 7 and open to the front so that the dentifrice can be discharged. Is preferably non-conductive to prevent direct contact. Further, the outer frame portion 8 is preferably elastic so that it does not hurt even if it contacts the gums.

  For example, as shown in FIG. 4B, the outer frame portion 8 of the cleaning operation unit 2 is formed of rubber and includes a radial polishing portion 26 that removes colored stains on teeth at the tip. The radial polishing portion 26 includes an outer cylindrical portion (outer frame portion 8) and an inner radial portion 27. There is a slight step 7 a between the outer frame portion 8 and the inner radial portion 27, and this step functions as the agent holding portion 7. Further, the void 7 b of the radial portion 27 also functions as the agent holding unit 7. That is, the dentifrice can be held in the step portion and the void portion.

  Further, as shown in FIG. 5 (a), the cleaning operation unit 2 is composed of a member whose tip is cut into a conical shape, and mainly removes colored stains at fine portions between teeth, Some are composed of a large number of brushes arranged in a circle as shown in 5 (b). The member in FIG. 5A is made of a conductive material and is electrically joined to the turntable 6. The conical outer surface that comes into contact with the teeth has a concavo-convex surface in the order of nanometers to millimeters and serves as the agent holding part 7. In the multiple brushes of FIG. 5 (b), the bristle bristle portion 29 that connects the rotary table 6 and the brush portion 28 is made of a conductive material. The outer frame portion 8 has a cup-like structure so as to surround the brush portion 28. The cup-shaped structure of the outer frame portion 8 serves as the agent holding portion 7 and prevents the dentifrice from being dispersed away from the periphery of the cleaning operation portion side electrode 6 during brushing by the brush portion 28. The above-described attachment unit 10 provided with different cleaning operation units 2 is detachably attached to the main body unit 11.

  When the operation switch 14 is turned to turn on the internal power supply 4, a current flows from the internal power supply 4 to the circuit 17, and the motor 15 for driving the circuit motion is driven, so that the motion conversion unit 18 rotates and the reciprocating drive body 19 is moved. Reciprocates linearly. The reciprocating drive body 19 and the slide shaft 20 are connected by a reciprocating drive joint portion 21, and the reciprocating drive body 19 performs a reciprocating linear motion, whereby the slide shaft 20 also performs a reciprocating linear motion. Then, as the slide shaft 20 reciprocates linearly, the turntable 6 reciprocates through the eccentric shaft 24 and the connecting piece 25 of the turntable 6. When the turntable 6 reciprocates, the entire cleaning operation unit 2 reciprocates to clean the teeth.

  At this time, the conduction path is formed with the gripping part side electrode 5 as a positive pole and the cleaning operation part side electrode 6 as a negative pole. The electric current from the grip part 1 flows to the body through the hand having the grip part 1 and finally flows to the teeth. The electric current from the teeth flows to the cleaning operation unit side electrode 6 through the dentifrice. The current from the cleaning operation part side electrode 6 flows to the eccentric shaft 24 made of a metal material, the slide shaft 20, the reciprocating drive joint part 21, the reciprocating drive body 19, and the motion converting part 18, and finally the gripping part side. Return to the electrode 5.

  The main body part 11 and the attachment part 10 are detachable, and the slide shaft 20 of the attachment part 10 is attached to and detached from the reciprocating drive body 19 inside the main body part 11 via the reciprocating drive joint part 21.

  The connection part 12 between the main body part 11 and the attachment part 10 is provided with a water intrusion prevention member 13. An example of the water intrusion prevention member 13 is packing. By providing this water intrusion prevention member 13, the apparatus is prevented from being deteriorated due to water intrusion, and leakage is prevented to ensure the safety of the user.

  Therefore, in the first embodiment, when the dentifrice is filled in the agent holding unit 7, the current is applied to the body from the gripping hand by energizing the gripping unit side electrode 5 and the cleaning operation unit side electrode 6. After finally flowing through the teeth, the blood flows to the cleaning operation unit side electrode 6 through the dentifrice of the agent holding unit 7. Since the stain has a positive charge and the agent has a negative charge, they attract each other and the stain removal effect is enhanced.

  The dentifrice may be a dentifrice containing a commercially available abrasive or may contain a salt.

  At this time, if a dentifrice containing a substance that is decomposed by electricity and becomes an effective charged molecule for stain removal, such as a fluorine-containing dentifrice, is further produced as the dentifrice.

  By energizing between the gripping part side electrode 5 and the cleaning operation part side electrode 6 with the dentifrice filled in the agent holding part 7, the current is finally passed through the body from the gripping hand. Then, it flows to the cleaning operation part side electrode 6 through the dentifrice of the agent holding part 7. Charged molecules having a negative charge are attracted to the teeth on the positive electrode side, and the concentration of charged molecules near the teeth increases. By increasing the number of charged molecules acting on the stain attached to the teeth, a chemical reaction having a stain peeling effect is promoted, and as a result, the stain removal effect is enhanced.

  In addition, by disposing the dentifrice in the agent holding part 7, it is possible to prevent the dentifrice from being dispersed in the oral cavity, and it is possible to efficiently move the charged molecules by intensively flowing the current. Can be removed intensively. Further, since the agent holding unit 7 can hold and release the dentifrice, the teeth can be brushed while passing an electric current through the dentifrice, and the stain removal effect is enhanced.

  And since the washing | cleaning operation | movement part 2 carries out reciprocating rotational movement, compared with the case where the washing | cleaning operation | movement part 2 carries out rotational movement like a general tooth cleaning apparatus, dispersion | distribution of dentifrice can be prevented.

  Moreover, since the bottom part of the agent holding | maintenance part 7 contact | connects the washing | cleaning operation part side electrode 6, since an electric current flows into a dentifrice reliably and a tooth | gear is cleaned with the dentifrice, the stain removal effect increases. And since the washing | cleaning operation part side electrode 6 and a tooth | gear become nearer than the conventional tooth cleaning apparatus, it is easy to energize and the stain removal effect increases.

  In particular, in this case, brushing the teeth with the cleaning operation unit 2 that reciprocates in a state where the stain removal effect is enhanced by energization enables faster and finer movement than the conventional manual operation, and the cleaning effect Will increase. Stain removal can be easily done even by children and the elderly who have little polishing power.

  Further, the gripping portion side electrode 5 is a positive electrode and the cleaning operation portion side electrode 6 is a negative electrode, so that the cleaning operation portion removes stains (colored dirt substances, spears, tea astringents, etc.) contained in saliva or water in the oral cavity. It is effective in attracting the side electrode 6 to enhance the stain removal effect.

  The user can perform cleaning in the oral cavity, particularly removal of colored stains, by placing the cleaning operation unit 2 against the teeth and gums in such a state. By cleaning the teeth while energized, a higher stain removal effect can be expected as compared with conventional tooth cleaning devices. Compared with a conventional tooth cleaning device, it makes it easier to carry charged molecules to stains attached to narrow grooves such as interdental parts and dented surfaces. At the same time, a colored substance having a positive charge is attracted from the tooth surface and saliva in the oral cavity to the electrode on the negative electrode side to prevent the colored stain component from being fixed on the teeth.

  And since the agent holding | maintenance part 7 consists of an electrically insulating material, the direct contact in the washing | cleaning operation part side electrode 6 and an intraoral area is prevented, and a user's safety is ensured.

  Moreover, since the attachment part 10 and the main-body part 11 can be divided | segmented, it becomes compact and carrying around becomes easy. And, by providing a water intrusion prevention member 13 between the attachment part 10 and the main body part 11 to prevent water intrusion, the deterioration of the equipment in the apparatus is prevented and the life of the apparatus is extended, and at the same time, the leakage is prevented and used. Person safety can be ensured. Furthermore, since the attachment part 10 and the main-body part 11 can be divided | segmented, it can replace and use for the washing | cleaning operation | movement part 2 of a favorite kind. Furthermore, since a plurality of attachment parts 10 can be exchanged for one main body part 11, the main body part 11 can be shared by a family.

  6, 7 and 8 show a tooth cleaning apparatus according to a second embodiment corresponding to all of claims 1 to 4. Here, only matters different from those in the first embodiment will be described, and other matters (configuration, operational effects, and the like) are the same as those in the first embodiment, and thus description thereof will be omitted. This tooth cleaning device 3 has an illuminating device 9 in the vicinity of the cleaning operation unit 2 for lighting and displaying the energization between the gripping unit side electrode 5 and the cleaning operation unit side electrode 6 in the tooth cleaning device 3 of the first embodiment. Is.

  Hereinafter, the tooth cleaning apparatus 3 of 2nd Embodiment is demonstrated in more detail. A lower part of the cleaning operation unit 2 is provided with an illumination device 9 for lighting and displaying energization between the gripping unit side electrode 5 and the cleaning operation unit side electrode 6.

  The turntable central shaft 23 and the reciprocating drive body 19 form a conduction path by the three conductors 30. The conductor 30 may be a wiring or a metal elastic plate piece such as a stainless steel lead piece. It is. The two conductors 30 on the turntable 6 side are respectively connected to the lighting device 9, and the conductor 30 on the main body part 11 side is connected to the reciprocating drive body 19 to form a conduction path. The reciprocating drive joint 21, the slide shaft 20, the connecting piece 25, and the eccentric shaft 24 are made of metal, which also constitutes a conduction path. The reciprocating drive joint 21, the slide shaft 20, the connecting piece 25, and the eccentric shaft 24 may be made of resin instead of metal. In this case, the conduction path is not configured, but weight reduction can be achieved by using resin.

  The electric current from the teeth flows to the cleaning operation unit side electrode 6 through the dentifrice. The current from the cleaning operation unit side electrode 6 is a rotating base central shaft 23 made of a metal material, a conductor 30a, a lighting device 9, a conductor 30b, a conductor 30c, a reciprocating drive joint 21, a reciprocating drive 19, and a motion conversion. A current flows to the portion 18 and finally returns to the gripping portion side electrode 5.

  Therefore, since the illumination device 9 is provided in the second embodiment, cleaning of teeth in places where it is difficult to confirm the position without illumination, such as the back of the teeth and the back teeth, becomes easy. Moreover, it can be confirmed whether the washing | cleaning operation | movement part 2 is contacting the tooth | gear appropriately. In addition, it also serves as a function of notifying the energized state during tooth cleaning, preventing the tooth cleaning in the non-energized state and maintaining the stain removal effect.

  In the first embodiment and the second embodiment, a chemical reaction having a stain peeling effect is promoted by setting the gripping part side electrode 5 as a positive electrode and the cleaning operation part side electrode 6 as a negative electrode. Although the stain removal effect is enhanced, the gripping part side electrode 5 may be a negative pole and the cleaning operation part side electrode 6 may be a positive pole. In this case, if the electrode contains a material that is effective for the oral cavity, such as silver, it dissolves and produces an effective effect.
