The specific embodiment

To describing with an example of ion brush in oral cavity of the present invention.

In Fig. 1 and Fig. 2, illustrated in the oral cavity as an example of the present invention and brushed with ion.As being toothbrush type with ion brush 1 in the oral cavity of an example of the present invention, there is the handle portion 20 that brushhead 10 and extension are arranged at the strip of brushhead 10.

(brushhead)

Brushhead 10 has resinous brushhead main body 11, be arranged at brushhead main body 11 inside electric conductor 12 and be implanted in a plurality of pieces 13 of planting hair side 11a of brushhead main body 11.

As the material of brushhead main body 11, there are acrylic resin (PP), acetal resin (POM), polystyrene resin (PS), saturated polyester resin (PCTA, PCTG), pet resin (PET), acrylonitrile butadiene styrene resin (ABS), polyarylate resin, polycarbonate resin and AS resin acrylonitrile styrene resin (AS) etc.As the material of brushhead main body 11, can use separately a kind of resin, also can be used together two or more resins.

Electric conductor 12 in this example is along being set near electric conductor top with the length direction of ion brush 1 from the cardinal extremity of brushhead main body 11 in oral cavity, consisting of conductive material.

Conductive material as forming electric conductor 12, is not specially limited, such as adopting platinum, gold, copper, stainless steel and material with carbon element etc.

At this, " brushhead main body 11 " refers to from implanting and is provided with the brushhead of pieces to the part of the boundary portion of handle portion.Again, " cardinal extremity of brushhead main body 11 " refers to the boundary portion of brushhead main body 11 and handle portion.

Near " top " of brushhead main body 11 refers to the tip side of the brushhead of implanting the pieces that is arranged at brushhead.

Pieces 13 in this example is implanted in and plants hair side 11a with cancellate arrangement roughly, is fixed in electric conductor 12 with the base end part of high-quality green tea end opposition side.

Pieces 13 stops up formation by many bristle 13a.Bristle 13a in this example as shown in Figure 3 and 4, is that cross sectional shape is broad wool circular, that end face 13b is made into single plane.In the situation that the end face 13b of bristle 13a is single plane, be suitable for the washing of facing.

Again, the bristle 13a in this example is the bristle of core sheath structure, and it has the core 13c of a columned electric conductivity that is disposed at its center, and to be with core 13c the dielectric covering part 13d that concentrically ringed shape is arranged on the side face of core 13c.As shown in Figure 5, in the end face 13b on the top of bristle 13a (being high-quality green tea end), core 13c exposes, and by exposing of core 13c, has formed the electrode (the first electrode) of inner side, oral cavity.That is, the first electrode in the present invention is on the high-quality green tea end of bristle, and the core of the electric conductivity being exposed by the dielectric covering part from bristle forms.Bristle 13a is fixed, and makes core 13c be electrically connected on electric conductor 12.Fixing means as from bristle 13a to electric conductor 12, can be suitable for deposited or bonding.

Core 13c forms by containing conductive material." electric conductivity " in the present invention refers to, specific insulation is 1.0 * 10 ⁵below Ω cm, be preferably 1.0 * 10 ⁴below Ω cm, be especially preferably 1.0 * 10 ³below Ω cm.As conductive material, such as there are the metals such as gold, silver; The metal oxide such as titanium oxide, zinc oxide; The material with carbon elements such as carbon black.At this wherein, from use this point and stability this point in oral cavity, be preferably material with carbon element, be especially preferably carbon black.

Above-mentioned conductive material can be used separately a kind of conductive material, the use of also two or more conductive materials suitably can being arranged in pairs or groups.

As the shape of conductive material, so long as powder, graininess etc. can be rubbed the shape into adhesive resin equably.Be preferably and in core 13c, except containing conductive material, also contain adhesive resin again.As adhesive resin, such as there are the polyester such as PETG (PET), polybutylene terephthalate (PBT) (PBT), PTT (PTT); The polyamide such as nylon 6, nylon 66, nylon 6-10, nylon 6-12, nylon 12; The polyolefin such as polyethylene, polypropylene; The polyvinylhalogenides such as Kynoar etc.

In the situation that core 13c contains adhesive resin, with respect to the total amount that forms whole constituents of core 13c, the amount of conductive material is preferably 10～60 quality %, is especially preferably 20～50 quality %.As long as the amount of conductive material, more than described lower limit, just can obtain sufficient electric conductivity, as long as below described higher limit, just can guarantee sufficient intensity.

Covering part 13d covers the side face of core 13c and by the position of the side face insulating of bristle 13a, non-conductive material, consists of." non-conductive " in the present invention refers to, specific insulation is 1.0 * 10 ¹²more than Ω cm, be preferably 1.0 * 10 ¹⁴more than Ω cm, be especially preferably 1.0 * 10 ¹⁵more than Ω cm.

As non-conductive material, can use dielectric thermoplastic resin.As dielectric thermoplastic resin, be not particularly limited, for example, can use the resin the same with above-mentioned adhesive resin.Again, can be identical with adhesive resin, also can be different.

More than the thickness of covering part 13d is preferably 5 μ m.In the situation that the thickness less than 5 μ m of covering part 13d cannot carry out spinning equably, can not guarantee the intensity of layer.As long as the thickness of covering part 13d, more than 5 μ m, just can be guaranteed sufficient insulating properties.

In addition, said " thickness of covering part 13d " for example refers to herein, in the profile shown in Fig. 4, from the outermost layer (most external of covering part 13d) of bristle, be attached to the line of bristle central part, from most external to covering part 13d with the distance of the boundary face of core 13c.

For the thickness of covering part 13d, can measure with the cross section of amplifying projector or microscope amplification bristle again.

The ratio of the core 13c in the cross section of bristle 13a and the area of covering part 13d (sectional area of sectional area/covering part 13d of core 13c) is preferably 20/80～70/30, is especially preferably 30/70～60/40.If the excessive words of ratio of the area of the core 13c in the cross section of bristle 13a, the situation that exists the position beyond the first electrode cannot utilize covering part 13d to insulate to core 13c, if the ratio of the area of the covering part 13d in the cross section of bristle 13a is excessive, exists and cannot make electric current fully flow through the situation of core 13c.

The thickness of bristle 13a is preferably 3～10mil (0.076～0.254mm), is especially preferably 5～8mil (0.125～0.203mm).As long as the thickness of bristle 13a is more than described lower limit, orthostatic is just improved, and cleaning property just becomes higher, as long as below described higher limit, it is appropriate that the wool elasticity of pieces 13 (arching one's back) just becomes, and each sensation of using is just better.

Again, bristle 13a can be that the many whole thicknesses of bristle are identical, also can consider usability, sweeping sense, cleaning effect, durability etc., and the bristle 13a of two or more different thicknesses is combined.

The example combining as the bristle of the different thicknesses to two or more, for example there are the tip side of toothbrush head portion use 8mil bristle, at other positions of toothbrush head portion, use the combination of the bristle of 7mil.Thus, can improve the power taking of scratching with respect to the dirt of molar.Again, there are the peripheral part of toothbrush head portion use 6mil bristle, at the central portion of toothbrush head portion, use the combination of the bristle of 7mil.Thus, can make to become soft to the contact of gum.

As the manufacture method of bristle 13a, there are the method by having used the melt spinning of coextruded profiled machine to manufacture.Specifically, by the first extruder, core 13c is formed to the resin melting of use, the resin melting of covering part 13d being used by the second extruder, from wire guiding nipple, spray core 13c forms the resin of use and the resin of covering part 13d formation use simultaneously, they are extended, can manufacture bristle 13a thus.

(handle portion)

Handle portion 20 has columned handle portion main body 21 and exposes the second electrode 22 in the part of side face of the base end side that is arranged at handle portion main body 21.

At this, " cardinal extremity of handle portion main body 21 " refers to the end of a side contrary with the connecting portion being connected with brushhead main body.

Again, in the inside of handle portion main body 21, be formed with the cavity that can take in as the battery A of power supply, and, be built-in with the first terminal 23 of a utmost point contact of battery A, the second terminal 24 and the distribution 25 of another utmost point contact of battery A.The first terminal 23 is connected in the second electrode 22, the second terminals 24 by distribution 25 and is connected with electric conductor 12.That is, core 13c is connected to power supply by electric conductor 12 and the second connecting terminals.As the material of handle portion main body 21, can use the resin same with the resin-phase that forms brushhead main body 11.Again, in order to improve controlling property, handle portion main body 21 also can part be covered by the resin such as softnesses such as elastomers.

As the material of the second electrode 22, the first terminal 23 and the second terminal 24, can use the material identical with the material of electric conductor 12 that forms the inside that is arranged on brushhead 10.

As power supply, can use one-shot battery or secondary cell, as long as service voltage is 1.5V～12V, both can in left and right.

(manufacture method)

Manufacture method as brush 1 in the oral cavity in this example with ion, is not specially limited, for example, there are following (a) and method (b).

(a) after the bristle 13a stopping up being organized into the approximate number amount of planting, pieces shape and the hair pointed shape of regulation, by means such as heating, the base end part melting of opposition side will be positioned at respect to high-quality green tea end, the molten mass contact that makes to form is thus also deposited in electric conductor 12, and is fixed in the inner chamber of metal molding die.Then, by in-molded method, brushhead main body 11 and handle portion main body 21 are carried out to moulding, after this, the second electrode 22, the first terminal 23 and the second terminal 24 are installed.

(b) pieces 13 is inserted to the inner chamber of metal die, the inner chamber of this metal die is provided with the pieces retaining hole keeping tying up the pieces 13 of many bristle 13a, adopts the means such as heating by the base end part melting of pieces 13 and forms molten mass.Then, under the state exposing in molten mass by resin filling in metal die, form pieces 13 implanted plant mao portion's casket.Then, with plant mao portion's casket and separate and manufacture brushhead main body 11 and the handle portion main body 21 that electric conductor 12 is installed.Then, make to plant a mao molten mass for portion's casket and be contacted with electric conductor 12, fixing after, the deposited means such as, laser cladding deposited by ultrasonic wave coating, high frequency are carried out deposited.After this, the second electrode 22, the first terminal 23 and the second terminal 24 are installed.

(using method)

An example by the using method of ion brush 1 in oral cavity is described.

User holds handle portion 20, makes hand touch the second electrode 22, then, brushhead 10 is inserted in oral cavities, and the core 13c that makes to expose on the top of bristle 13a touches oral cavity organization's (between facing, tooth etc.).Thus, oral cavity organization and core 13c are conducted, make electric current with following path flow mistake: another utmost point of the core 13c of a utmost point of battery A, the first terminal 23, distribution 25, the second electrode 22, user's hand, health, oral cavity organization, bristle 13a, electric conductor 12, the second terminal 24, battery.And, to scrubbing and clean between facing and tooth.In addition, about sense of current, as long as according to the effect as object, or as hereinafter described in the situation that use the active ingredient of using in oral cavity to carry out correspondingly suitably selecting according to its kind.

In oral cavity, during with the use of ion brush 1, consider the Weak current that flows through a few μ A～tens μ A left and right in body, but can not produce the problem in safety.It would be better to say that, because small electric current flows through gum, can promote the blood circulation of gum, obtain the activation of gingiva tissue.

In with oral cavity, with ion brush 1, rinse the mouth when interior, also can use the active ingredient of washing use in the oral cavity in.At this, as active ingredient, there are dentine strengthening composition, sterilization component, anti-inflammatory composition, antioxidant content etc., be preferably the active ingredient of using in oral cavity internal ionization.In intraoral cleaning with ion brush 1 in using oral cavity, due to electric current is flow through in oral cavity, therefore, as long as use the active ingredient of ionization, just can utilize the principle of electrophoresis to be easily impregnated into target site.

As dentine strengthening composition, there are the fluorine compounds such as sodium fluoride, sodium monofluorophosphate, tin fluoride.

As sterilization component, there are Cetylpyridinium Chloride, benzalkonium chloride, benzethonium chloride, the Dequalinium Chloride of quaternary ammonium salt bactericide, chlorhexidine gluconate of biguanides bactericide etc.

As anti-inflammatory composition, there are tranexamic acid, ε caproic acid, β-glycyrrhizic acid, dipotassium glycyrrhizinate etc.

As antioxidant content, there are the vitamin C inductors such as ascorbic acid, magnesium ascorbyl phosphate.

In the oral cavity of this example, with ion, brush in 1, due to the core 13c coating cap 13d covering of bristle 13a, so being insulated of part of coating cap covering.Again, on the high-quality green tea end of bristle 13a, the core 13c in end face 13b exposes, and this part exposing becomes the electrode (the first electrode) of inner side, oral cavity.The part that therefore, can only make end face 13b that electric current flows through bristle 13a contact in oral cavity.

Therefore, in oral cavity during with the use of ion brush 1, electric current is difficult to flow to the position beyond target site, and the service efficiency of electricity is high.

Again, because electric current is difficult to flow to the position beyond target site, so in the situation that carry out intraoral cleaning and use the active ingredient that can ionize, can make active ingredient be impregnated into expeditiously intraoral target site.

(other examples)

In addition, the present invention is not limited to above-mentioned example.

The hair cutting profile (face shaping) that toothbrush is planted mao portion can not be also single plane shape, can be chevron cutting profile, can be also concaveconvex shape.Again, planting the outside of mao portion and the shape of inner side also can be different.

Again, the top end face of bristle (being high-quality green tea end) and with respect to high-quality green tea end, be positioned at the shape of the cardinal extremity face of opposition side also can be different, for example, the bristle that as shown in Figure 6, the end shape that can be also bristle 13a is cone-shaped, consist of core 13c and covering part 13d.In the situation that the end shape of bristle 13a is cone-shaped, be suitable for the cleaning between tooth.Again, the end shape of bristle can be also scoop shape, doctor-like, spherical etc.

Cross sectional shape perpendicular to the length direction of bristle is not limited to circle, can be oval, the polygon such as triangle, quadrangle, stars etc. can be also trilobal, the shape of quatrefoil isoline combination with one another, the shape of curve combination with one another or be further the combined shaped of straight line and curve.

The arrangement of the pieces in brushhead needs not be grid and arranges, and can be to be also staggered or asymmetrical arrangement, or other any arrangements.The arrangement of pieces need to be with respect to the axis of the length direction of brushhead and symmetry yet.

Again, bristle can not be also the bristle of core sheath structure, can be also that the core portion of being insulated that for example consists of multirooted teeth brush silk covers, cross section is the bristle of island structure.One example as bristle with the form of the core consisting of multirooted teeth brush silk, Fig. 7 shows the bristle of the covering part 13d with the core 13c consisting of 3 tooth brush monofilament 13e and the side face that covers described core 13c.Even if be formed by multirooted teeth brush silk in the situation that at core 13c, due to the side face coating cap 13d insulating of bristle 13a, so also obtain the effect the same with above-mentioned example.

Again, handle portion main body can not be also cylindric, that is, perpendicular to the cross section of length direction, can not be also circular, for example, can be oval, can be also that cross section is polygon (triangle, quadrangle, pentagon, hexagon etc.).

Again, the second electrode also can not be arranged on the base end side of handle portion main body 21, so long as in using oral cavity the part of user's hand contact during with ion toothbrush, be not particularly limited.

According to the shape of electric conductor and the second electrode, also can omit the first terminal, the second terminal and distribution again.

As power supply, use external power source to replace battery also to have no relations again.

As external power source, jumbo battery can be arranged on to outside, with connecting line etc., to ion brush in oral cavity, carry out power supply supply, also can home-use AC power supplies be depressurized to 1.5V～12V with resistor and use.

Again, in oral cavity of the present invention, with ion brush, can not also toothbrush type, can be brush type between tooth.Between tooth, brush type ion brush for example can be with following manufacture method manufacture.

That is, first, the tooth brush monofilament that forms the electric conductivity of core is sandwiched to the metal wire after turnover, and metal wire is screwed up, after the tooth brush monofilament of electric conductivity is fixed, whole with non-conductive material coating.Thus, just obtain having formed in the outside of the core being formed by electric conductivity tooth brush monofilament the bristle of covering part, and formed brushhead.Now, because does not expose on the top of core, thereby therefore block the top of bristle and make core exposed form the first electrode.Then by utilizing the insert-molding of ejection formation, handle portion is carried out to moulding, and the cardinal extremity of metal wire is connected in to handle portion.After this, the second electrode, the first terminal and the second terminal are installed, are obtained the ion brush of brush type between tooth.

Industrial applicability

High by the electric service efficiency of ion brush in oral cavity of the present invention, again, in the situation that use the active ingredient that can ionize, can make active ingredient be impregnated into expeditiously intraoral target site, industrial exceedingly useful.
