Below, the embodiment shown in illustrates the present invention with reference to the accompanying drawings.
At first, Fig. 1 to Fig. 3 represents the first embodiment of the present invention.Toothbrush shown in this embodiment is made of with the handle portion 16 of laying battery 14 the bristle portion 12 that implants bristle with being integral.The position of handle portion 16 close bristle portions 12 forms the circular batteries placed hole 18 of laying battery than broad on the surface of this position.This arranging batteries hole 18 forms along the direction parallel with the longitudinal axis of handle portion 12.
In this arranging batteries hole 18, lay discoid battery 14, as button cell.Central bottom in arranging batteries hole 18 forms a spring mounting hole 22 that diameter is less communicatively, in spring mounting hole 22, puts into as coil spring, and helical spring and other suchlike spring 24, this spring 24 contacts with an electrode of battery 14.The fulcrum 26 that conductive material constitutes is configured to expose in this spring mounting hole 22, and this fulcrum 26 is contacted with the bottom of spring 24, thereby fulcrum 26 is connected with an electrode of battery.
Especially as shown in Figure 3, at the position that battery 14 is installed, a conductive plate 32 that is formed by conductive material closely is installed with respect to brush holder 16.That is to say that the cross section is that the conductive plate 32 of Contraband font is installed on the brush holder 16 with another the top electrode that is positioned at battery 14 by protuberance 33 with becoming contact condition.For making battery keep the water proofing property sealing, in the space that is formed with around the arranging batteries hole 18 between 34, one sealings of ditch are inlaid in this ditch 34 and conductive plate 32 with O type circle 36 the inner surface with outside.The cross section is that the open end of the conductive plate 32 of Contraband font is bent to form kink 38 respectively to the inside, and these two kinks 38 are flexibly cooperated with anticreep groove 40 on the bottom that is formed on brush holder 16, thereby, can prevent that this conductive plate 32 from splitting away off from brush holder 16.
Form symmetric rake 42 respectively on the two sides of the brush holder 16 of this position, this rake 42 has a slope that slowly broadens from the brush holder face that faces down.Therefore, the top width of brush holder 16 that is positioned at this place is narrow, for example, at the most and the width between a pair of kink 38 at the place, open end of above-mentioned conductive plate 32 basic identical.
The function of the ion toothbrush that constitutes with upper type as known in the art, touch conductive plate 32 and arrest brush holder 16 with hands, when brushing teeth, because of liquid such as saliva make bristle 10 moistening, by means of contained liquid in the connectivity slot 30, form a conductive path, make 26 one-tenth states that can be communicated with conductively of bristle and fulcrum.Thus, electric current from battery 14 through staff, human body, tooth, contained liquid in the bristle 10, connectivity slot 30, fulcrum 26 flows to battery 14 again, because potential difference, can improve when brushing teeth tartar and remove effect.
In the manufacture process of this ion toothbrush, when being installed to conductive plate 32 on the brush holder 16, very trouble and needs firmly just can fulfil assignment at present.Promptly, as shown in figure 15, this Figure 15 represents existing ion toothbrush and sectional view Fig. 3 same position, because wherein brush holder 16 is the square-section substantially, when conductive plate 32 is installed, must make the kink 38 of open end remain on the above operation of width of brush holder 16, and will keep the state of this width on one side, on one side conductive plate 32 is installed on the brush holder.Yet, according to the foregoing description owing on the brush holder two sides, formed rake 42, the operator is unnecessary pull with handgrip conductive plate 32 wide, and as long as the original state during with shaping presses down from the open end to brush holder 16.Therefore, as above-mentioned embodiment, under the situation that kink 38 is arranged, this kink 38 afterwards, arrives rake 42 glossily by the width above the brush holder.In this state, when conductive plate 32 was depressed, opened along rake 42 open end, and afterwards, because of surpassing the bight of brush holder bottom side, flexibly in the embedded groove 40, installation exercise finishes kink 38.Therefore, can make the installation exercise automatization of this conductive plate 32.And, can reduce the cost of manufacture of ion toothbrush more.
Because bristle portion 12 and brush holder 16 constitute one, can make the exposed portions serve of fulcrum 26 only be positioned near bristle 10 (only being connectivity slot 30 parts).Therefore, can prolong distance, can prevent that aforesaid liquid (unnecessarily) from immersing ion toothbrush inside simultaneously from this exposed portions serve to battery.The result is to suppress the generation of the electric leakage of battery 14 and the corrosion of electrode etc.
In the present embodiment, because form thin cervical region 28 as core with fulcrum 26, so, can improve the intensity of this part.The result can make thin cervical region 28 become very thin, can make when brushing teeth more convenient.In addition, because also can make fulcrum 26 itself thinner, so, in the weight that can alleviate ion toothbrush, can reduce fee of material.
In addition, in the present embodiment, because conductive plate 32 is installed on the outer surface of vertically approximately middle part of ion toothbrush, and being located in the battery 14 and conductive plate 32 corresponding positions, so, when living brush holder 16, do not having to touch conductive plate 32 very naturally under the situation of sense of discomfort with handgrip.Can shorten the length of fulcrum 26, also just can alleviate the weight of ion toothbrush naturally.
Because present embodiment is a kind of toothbrush that bristle portion 12 can not discard replacing, so the life-span and bristle 10 wear lifes that are preferably battery 14 are complementary.Therefore, also can make battery 14 miniaturizations.Thus, can provide cheap lightweight ion toothbrush.
Because in the present embodiment, bristle portion 12 and brush holder 16 are integral, so, can fulcrum 26 exposed portions serve only be arranged on bristle portion 12 bristle 10 near.Also just can be only this exposed portions serve as submerged gaps such as water or salivas.Therefore, can prolong from this exposed portions serve to battery 14 distance, simultaneously, prevent that aforesaid liquid from unnecessarily immersing the inside of toothbrush.Therefore, the electric leakage of battery 14 or the corrosion of electrode etc. have been suppressed.In addition, because can form thin cervical region 28 as core with fulcrum 26, so, can improve the intensity of this part.And, can form thinner thin cervical region 28, make brush teeth more convenient.But because also refinement of fulcrum 26 itself, so, the weight of toothbrush can further be alleviated.
Further, because bristle portion 12 and ion toothbrush that brush holder 16 constitutes with being integral can use the battery 14 with the corresponding effect of life-span of bristle 10, so, can also make battery 14 miniaturizations, simultaneously, can reduce the cost of battery 14 itself.
Below, according to Fig. 4 to Figure 14 the 2nd embodiment of the present invention is described.In this second embodiment, bristle portion 120 uses different materials with brush holder 160, and, be installed on the bristle 160 with can adorning folding, therefore, when discarded, need only the bristle portion 120 that changes.In this embodiment, the parts identical with first embodiment adopt identical symbol, in addition, omit the explanation of these parts.
In the present embodiment, the separation point position of bristle portion 120 and brush holder 160 is compared with the situation of existing ion toothbrush, near bristle portion 120, that is, is positioned at thin cervical region 28 places, and therefore, bristle portion 120 compares with existing bristle portion, can do forr a short time.
Especially, as shown in Figs. 8 to 11, bristle portion 120 is integral the extended shank 48 that connects in ground and constitutes by mao portion 46 of planting that implants bristle 10 with from planting mao portion 46.Connect shank 48 as previously mentioned, connect shank and compare with existing, size is extremely short.Connect the axial of shank 48 along this, be formed with from connecing pommel portion first hole 50 that begins and the diameter that links to each other with this first hole 50 second hole 52 littler than this first hole, these two holes are formed with the fulcrum insertion section.
Connect the top of shank 48, that is, dug a joint-cutting from meeting pommel portion vertically to position, form connectivity slot 30 as an above-mentioned liquid road part by this joint-cutting near bristle 10 in a side of bristle 10.
And for example Figure 12 is to shown in Figure 14, fulcrum 26 is outstanding vertically from the end of brush holder 160, or rather, extension 62 extends outward predetermined length from the end of brush holder 160, this extension 62 includes fulcrum 26 and its upper side has a pair of engagement protrusion 60, and fulcrum 26 only extends outward a relatively shorter distance from this extension 62.Extension 62 is the part in first hole 50 of the above-mentioned bristle of insertion portion 120, and outstanding fulcrum 26 is for be inserted into the part of 52 bottoms, second hole always.Engagement protrusion 60 and cooperating recesses 58 flexibly chimeric (with reference to Fig. 4), thus, bristle portion 120 can not extract from handle portion simply vertically very much.That is to say that this structure provides a kind of bristle portion 120 that can make just to be connected with the brush holder once-through operation vertically, after connection finishes, does not apply the above strength of certain force, and bristle portion 120 is broken away from from brush holder 160 vertically.Therefore, this axially connects structure is to utilize the upper side of extension 62 to form, and that it goes without doing is very roomy for this part, has a thin cervical region just passable.
Therefore, the axial syndeton that forms according to the engomphosis relation by cooperating recesses 58 and engagement protrusion 60, the anti-rotation structure that is formed by the matching relationship of mating groove 56 and engagement protrusion 64 and the brush of fulcrum front end and retaining tongue 54 are pressed supporting structure, even, bristle portion 120 is detachable structure with respect to brush holder 160 at thin cervical region place, thin cervical region can chap yet, bristle portion 120 can reliably and have height and be connected with brush holder rigidly, and in use, bristle portion 120 can not split away off.Especially, in this embodiment, because in fact the length of Tu Chu fulcrum 26 is extremely short, so, even consider that from the angle that reduces fee of material do the diameter of fulcrum 26 less, its intensity can not be damaged yet.
Fig. 6 is the sectional view of the VI-VI line along Fig. 4.In this embodiment, be arranged on brush holder 160 lateral rakes 42 and see from top to bottom as illustrated in fig. 4, only be set on four angles.Its reason is shown in first embodiment such, when the two sides of brush holder are provided with rake continuously, in order to avoid battery 14 or O type circle 36, have to widen the integral width of brush holder, for preventing this phenomenon, avoid the ledge of broad ways such as battery, only on four jiaos, form rake 42, just can widen brush holder 160, therefore, as shown in Figure 7, the middle part, side of conductive plate 32 forms an otch 39, thereby, when mounted, as shown in Figure 6, this otch 39 ends at the lateral centre of brush holder 160, even such embodiment needn't open the open end with palm for conductive plate 32 is installed, as long as simply conductive plate is pressed onto institute's allocation.
Below, Figure 16 and Figure 17 represent the 3rd embodiment of the present invention, connectivity slot 30 in a second embodiment is for the seam shape and be formed into the pommel portion that connects always, axially the cooperating recesses 58 of syndeton is arranged on the two sides of connectivity slot 30, and in the present embodiment, make connectivity slot 30 and axially johning knot formation setting independently of each other.That is to say that connectivity slot 30 and joint-cutting portion 49 with above-mentioned cooperating recesses 58 are by separating with bristle portion 120 all-in-one-piece strut rails 31.In the present embodiment, form above-mentioned brush by strut rail 31 and fulcrum 26 relations and press supporting structure, therefore, needn't need the retaining tongue 54 that must be provided with among second embodiment.
Figure 18 represents the fourth embodiment of the present invention.Fulcrum 26 is outwards not outstanding from the end of brush holder 160, but ends at the position that concaves from this end face.Therefore, on the end face of brush holder 160, formed always opening to the preceding end slot 128 of fulcrum 26.
As shown in figure 18, near the bristle 10 of bristle portion 120, the cross section is that two open ends of the conductive plate 127 of FangZi Zhuan are inserted into respectively in groove 130 and the groove 131, and be exposed to bristle portion plant the hair side side.Axis hole 132 is connected with above-mentioned groove 131, and to the longitudinal extension of bristle portion 120 and penetrate into the end face of bristle portion 120 always, a spring that is made of conductive material is inserted in this axial hole 132, this spring utilizes a kind of suitable means to be fixed on the conductive plate 127, and its other end extends from the end face of bristle portion 120.This spring 126 is fixed on the conductive plate 127 and becomes electric conductivity to be connected through the interconnecting part of groove 131 and axis hole 132.In addition, the length from the extended part of end face of bristle portion 120 of spring 126 is longer than the degree of depth that is formed on the groove 128 on the brush holder 160.
When installing to the bristle portion 120 that has a this structure on the brush holder 160, the front end from the extended spring 126 in the end of bristle portion 120 is inserted in the groove 128 on the end face that is formed on brush holder 160.By such mode, fulcrum 26 keeps electric conductivity to be connected because of the elastic force of spring 126 with conductive plate 127 really.
