With reference to Fig. 8, the occupation mode of the electric toothbrush 1 of having used toothpaste 80 is described.
Before beginning to brush teeth, when the user had been coated onto toothpaste 80 on the leading section of conduction brush pieces 50 and insulated brush pieces 60, the part of toothpaste 80 was stored in storing section 34.
As shown in Figure 8, when the user had carried out brushing teeth, the part of toothpaste 80 was consumed.At this moment, than the toothpaste 80 of storing section 34 outsides, promptly be positioned at the toothpaste 80 of insulated brush pieces 60 front ends, the toothpaste 80 that stores in storing section 34 is difficult to be consumed.Therefore, the toothpaste on the leading section that is coated onto insulated brush pieces 60 80 be consumed during, by the energising, with toothpaste 80 ionizations of storing section 34.
As toothpaste 80, to use when containing the toothpaste of electrolyte effective component, the function of current enters into oral cavity tissue to effective component.When this effective component has bactericidal action, can be to carrying out sterilization in the oral cavity.
According to the toothbrush of above-mentioned the 3rd embodiment, except the effect of (3)~(5) of (1) and (2) of the 1st embodiment and the 2nd embodiment, can also obtain following effect.
(6) storing section 34 by each conduction brush pieces 50 front ends forms 1 storing section.Therefore, when brushing teeth, can be to more toothpaste 80 action currents.In addition, when the user is coated onto toothpaste 80 on the brushhead 11, can further easily carry out only on storing section, being coated with the operation of toothpaste 80 before brushing teeth.
In addition, above-mentioned embodiment also can be out of shape in the following manner.
In the 1st embodiment, the height that mixes bristle tuft 70 is all identical, but also can be set at different height.That is to say, in mixing bristle tuft 70, electric conductivity bristle 30 is different from the height of reference plane from the height and the insulating properties bristle 40 of reference plane, and certain mixing bristle tuft 70 is also different from the height of reference plane from height and other mixing bristle tuft 70 of reference plane.In this case, for example as shown in Figure 5, can so that the height of mixing bristle tuft of base end part, leading section and central portion that is disposed at the length direction of brushhead 11 greater than the height of in addition mixing bristle tuft.Perhaps, as shown in Figure 7, also can so that in the mixing bristle tuft that disposes on the base end part of brushhead 11 and the leading section than being configured in 2 mixing bristle tuft height that mix between the bristle tuft.
And, as described in above-mentioned variation, certain mixes bristle tuft 70 and is different from other from the height of reference plane and mixes bristle tuft 70 under the situation of the height of reference plane, and the height that constitutes the height of each electric conductivity bristle 30 that mixes bristle tuft 70 and insulating properties bristle 40 also can be identical.
In the 1st embodiment, plant the even surface of hair side 13, but for example also can change in the following manner on the length direction of brush body 10, extending.That is to say that as shown in figure 10, the mixing bristle tuft 70 that is positioned on the middle body of length direction of brushhead 11 is the highest, towards both ends, mixes the height step-down of bristle tuft 70 from middle body, will plant hair side 13 and form curved shape.Under this situation, when each base end part that mixes bristle tuft 70 of equal length was implanted in the brushhead 11 with equal length, the height from the datum level to the front end between the adjacent mixing bristle tuft 70 was different.In addition, in this variation, when the face that will plant hair side 13 reverse side was made as the benchmark of short transverse, virtual (face among the figure shown in the dotted line) of the middle body by planting hair side 13 was set to the datum level by the highest point of planting hair side 13.
In the 1st embodiment, electric conductivity bristle 30 is low from the height of reference plane from the aspect ratio insulating properties bristle 40 of reference plane, but electric conductivity bristle 30 also can be than the height height of insulating properties bristle 40 from the height of reference plane.In this case, form storing section at insulating properties bristle 40 front ends.Therefore, the toothpaste of electric conductivity bristle 30 front ends is consumed earlier than the toothpaste that stores in the storing section of insulating properties bristle 40.Therefore, the front end of electric conductivity bristle 30 directly contacts with gum, hinders thereby can suppress contacting by toothpaste between electric conductivity bristle 30 and the gum.The electric massage effect that therefore,, can obtain warm gum, carry out anti-inflammatory etc. by inflow current.In addition, also be used as the toothpaste that composition contains heat-storage agent or exothermic mixture this moment, can further improve above-mentioned electric massage effect by accumulation of heat effect or heating effect.
In the 1st embodiment, the electric conductivity bristle 30 that constitute to mix bristle tuft 70 is low from the height of reference plane from the aspect ratio insulating properties bristle 40 of reference plane, but can be height height than insulating properties bristle 40 from the height setting of reference plane with electric conductivity bristle 30 also.In this case, on the front end of insulating properties bristle 40, form storing section.Under this situation, than the toothpaste that stores in the storing section of insulating properties bristle 40, the toothpaste 80 that is coated on the front end of electric conductivity bristle 30 is consumed earlier, so can access the action effect identical with above-mentioned action effect.
In addition, electric toothbrush 1 is provided with and constitutes the electric conductivity bristle 30 of core 31 from the outstanding structure of coating portion 33.Therefore, core 31 enters into the slit of oral pocket etc., carries out the sterilization of bacterium thereby can enough chlorine concentrate.In addition, the core 31 outstanding energising areas that make increase, so can improve electric massage effect.In addition, because being insulated property of part parts, i.e. 33 coverings of coating portion in addition of the leading section of core 31, so electric current is concentrated the leading section that offers core 31.Thus, can further improve electric massage effect.
In addition, in the 2nd, the 3rd embodiment, is lower from the height of reference plane than insulated brush pieces 60 with conduction brush pieces 50 from the height setting of reference plane, but can be height height than insulated brush pieces 60 from the height setting of reference plane with conduction brush pieces 50 also.In this case, also can bring into play the action effect identical with above-mentioned variation.In addition, when the user is coated onto toothpaste 80 on the brushhead 11, carry out only on storing section, being coated with the operation of toothpaste 80 easily before brushing teeth.
In the 2nd embodiment, the higher insulated brush pieces 60 of configuration on base end part, leading section and the central portion of the length direction of brushhead 11, but for example also can on central portion, dispose higher conduction brush pieces 50, the higher insulated brush pieces 60 of configuration on base end part and leading section.In addition, also can on base end part and leading section, dispose higher conduction brush pieces 50, at the higher insulated brush pieces 60 of central portion configuration.
In each embodiment, electric conductivity bristle 30 height from reference plane each other is all identical, and insulating properties bristle 40 height each other is also all identical.In other words, the height of bristle only is divided into 2 layers, but also can adopt the height more than 3 layers to constitute.For example, as shown in Figure 9, can be lower also than the height of other conduction brush pieces 50 with the height setting that is implanted to the conduction brush pieces 50 of central portion.Under this situation, can further increase and suppress the effect that effective component escapes to the outside.
In each embodiment, comprise that brushhead 11 and brush holder 12 constitute brush body 10, but also can remove brush holder 12 constitutes brush body 10.Under this situation, can be with the part of the brush holder 12 that is removed with to control main part 20 integrally formed, perhaps also can form as other important documents that are independent of brushhead 11 and control main part 20.
In each embodiment, the present invention has been applied in the oscillatory type electric toothbrush, but also the present invention can be applied in the rotary electric toothbrush of the part rotation that makes the brushhead of having implanted bristle.In addition, also the present invention can be applied in the toothbrush of the function of having omitted the function that makes the brushhead vibration or having made the brushhead rotation.
