The specific embodiment
Below, will describe toothbrush of the present invention in detail.
Might become molar, canine tooth and the wisdom tooth of decayed tooth, have rounded outer surface.Therefore, longer than the length of the bristles in the centre that is arranged on head 11 if be arranged on the length of the bristles in the outward flange of head 11, as the present invention, bristles and each all are that circular interdental contact surface will increase so.Like this, when the interdental contact surface of bristles and each increases, teeth surfaces scrub efficient and ability also can improve.
Under the situation of vertically brushing teeth, can thrust between the tooth easily along the brachydont bristle that is horizontally installed in the toothbrush.The long teeth bristle that longitudinally is fixed in the toothbrush can teeth surfaces, and can successfully thrust the formed periodontal of the intersection district between tooth and the gums simultaneously.At this moment, the length difference between each brachydont bristle and each the long teeth bristle is suitable in the scope of 1.5mm to 3.5mm.If length difference surpasses the scope of above-mentioned 1.5-3.5mm, bristles and interdental contact surface will reduce.
In the present invention, the group that term " bristles that is provided with in the cross mode " expression has bristles is arranged on the toothbrush with complete vertical and horizontal, and in addition, the group can be arranged on the toothbrush in 30 degree scopes with respect to the vertical and horizontal line of toothbrush obliquely, that is, arrange with the zigzag pattern.If the group tilts in above-mentioned angular range, this toothbrush can reach purpose of the present invention so.
Needle-like hair is represented the bristles that reduces from the root to the end diameter, like this can be soft, and have thrust between the tooth or be formed at tooth and gums between the good ability in slit between the periodontal district of intersection.Therefore, recently, needle-like hair gets consumer reception very much.In the method for making needle-like hair, a kind of method is the end of mechanical lapping bristles, and a kind of method is that bristles is immersed in acidity or the alkali electroless medicine, to dissolve its end.
The thickness of the end points of employed each needle-like hair is in 0.01mm to 0.03mm scope among the present invention.Preferably, can use various needle-like hairs with the end points that drops on the different-thickness in the above-mentioned scope.And the tapering length of employed each needle-like hair is in 5mm to 12mm scope among the present invention.And preferably, can use various needle-like hairs with tapering of dropping on the different length in the above-mentioned scope.When use has the various needle-like hair in different-thickness end points and different length tapering, can demonstrate suitable piercing and good cleaning capacity, in addition, can also improve the service life of toothbrush.If the thickness of the end points of each needle-like hair is less than above-mentioned scope, cleaning capacity will reduce.In addition, if the thickness of end points on above-mentioned thickness range, the hardness of needle-like hair will increase.Therefore, user's gums may be owing to using needle-like hair to damage when brushing teeth.In addition, if the tapering length of each needle-like hair does not reach above-mentioned length range, then the hardness of needle-like hair will excessively increase.If the tapering length of each needle-like hair is greater than above-mentioned length range, then cleaning capacity will reduce.
The method of making traditional toothbrush is very simple, and this toothbrush and has a plurality of small circular grooves that wherein are fixed with a plurality of bristles as shown in Figure 1.That is to say, bristles is fixed in each circular groove, afterwards, with the fastening bristles of supporting pin, as shown in Figure 4.In the traditional toothbrush of making by said method, each circular groove has the diameter of about 1.6mm.Therefore, even after with the fastening bristles of supporting pin, do not carry out post processing, the exposed length that is fixed on the bristles in the circular groove also is geostationary.Like this, can directly use by the traditional toothbrush of said method manufacturing, and need not other post processing.
The method that bristles is fixed in the groove of toothbrush of prior art 2 is identical with the method for toothbrush shown in Figure 1.But, because being formed at each groove on prior art 2 toothbrushes, relatively large (minor axis length is in 1.0mm to 2.0mm scope, long axis length is in 3.0mm to 4.5mm scope), must use the extension supporting pin that has with the groove shapes similar shapes that bristles is fastened in the groove.Therefore, a large amount of bristles are fastened under the situation in the groove use extending supporting pin, the exposed portions serve length that is fixed on the bristles in prior art 2 toothbrushes is different, unlike the traditional toothbrush with small circular groove.So, in the toothbrush of prior art 2, after being fixed to bristles in the groove, need to carry out independent shearing technology, cut flat with irregular exposed portions serve bristles.In addition, when the end of bristles exposed portions serve is cut off, bristles residue end portion thickness will increase.Therefore, need independent grinding technics, so that bristles comes to a point.Like this, owing to increased independent technology, reduced machinability.In addition, although carried out grinding technics, the thickness of bristles end points is still relatively large.Therefore, prior art 2 remains problematic in the bristles of toothbrush aspect coarse.
In toothbrush of the present invention, the groove of oval-shaped a plurality of elongations is formed in the head of toothbrush body.Like this, the invention solves and the relevant problem of prior art 2 toothbrushes.When bristles was fixed in the toothbrush, the reason of the irregular formation of length of the bristles of prior art 2 was that the groove of prior art 2 is greater than the circular groove of traditional toothbrush.But, prove that through repeated test than the prior reason of above-mentioned reason be, each groove of prior art 2 is a rectangle.That is to say, although the groove of elongation of the present invention all has the size identical with the groove of prior art 2, if the groove of elongation be oval or be similar to oval-shaped reservation shape, just solved the irregular fixation problem of bristles.Be similar to oval-shaped reservation shape and be meant that each bight is the rectangle of fillet, as shown in Figure 5.The toothbrush of the present invention that provides by above-mentioned technology is shown in Fig. 6 and Fig. 7.
In order to improve the piercing of bristles, after bristles is folding, each needle-like hair is fixed in each elongated groove, from there being the difference in height of 0.5-1.5mm between the folding needle-like hair both ends.It is arranged so that the needle-like hair that has difference in height between the end, is arranged so that than it concordant bristles in both ends has the better ability of thrusting.
