The adoption of the measures realizes that the toothbrush head universally rotates, toothbrush bristles can be distorted along with the arrangement way of the teeth in the oral cavity, the toothbrush bristles can be evenly and tightly applied to the inner side and the outer side of the dentition and the occlusion surface, the bristles with high external part and low internal part can replace a toothpick to keep the food being clipped and hidden between the teeth picked cleanly, the brushing rate is reached to or close to 100 percent, and the injury to the gum and the enamel is prevented when the teeth are horizontally brushed, the effect of massaging gum is achieved, thereby having prevention and treatment functions on the irregular dentition of children, and having prevention and treatment functions on the tooth stone calculus and the gum of various crowds.

Description

Toothbrush

The utility model relates to daily living article toothbrush class.

At present, the toothbrush that we use always, it mostly is straight-bar shape toothbrush, its brush is fixed, can not freely rotate, the bristle of this kind toothbrush can not be fit to the arrangement mode of the uneven tooth that varies with each individual in the oral cavity well, when brushing teeth horizontal brush especially in the horizontal direction gums and enamel is had to a certain degree damage.Cause shallow bleeding gums, atrophy easily and make tooth mobility and come off in advance, it is damaged to make neck portion occur carving shape.The T-shape toothbrush of Chu Xianing afterwards, perhaps further improved crank T-shape toothbrush is gone up on the basis thus, and the toothbrush of other kind, in use also touches less than the tooth of position by the lining, does not conform to the oral health care requirement.I once proposed a kind of toothbrush at ZL98211833.3, but found that in actual use brush plants the basic manufacturing process complexity of hair, and cost is too high, is not suitable for masses and promotes the use of.

The purpose of this utility model provides the toothbrush after a kind of improve, its brush and brush holder Hook's coupling, brush plant Mao Ji Free Transform within the specific limits, to adapt to the tooth of uneven arrangement.

The purpose of this utility model is achieved in that the utility model is made up of brush and brush holder.In the one side that Mao Jiwei plants hair of planting of brush, have the groove of 2-4 dark about 4mm at interval; Plant the middle part of hair one side planting Mao Jiwei, a protuberance is upwards arranged, ridge caves in inwards from the top, forms a most spherical depression hole, and the diameter of depression hole opening part is less than the internal diameter in the hole of caving in; The button of brush holder is spherical, and its size to be can freely rotating in the depression hole, and not having than under the external force effect greatly, can not come off out and be advisable.When the button of brush holder embeds in the depression hole of planting on mao base, form Hook's coupling between brush holder and the brush;

Brush of the present utility model longitudinally forms about 15 ° garden arc when injection moulding;

Secondly, being shaped as of bristle of the present utility model: for becoming mildewed, bristle shortens gradually in the middle of two side direction along the horizontal both sides of the edge of brush, and from end face, bristle arrangements is a circular arc, designs like this, can effectively reject the thing of mailing in the teeth space when brushing teeth.

Described in detail below in conjunction with accompanying drawing:

Fig. 1 is a structure diagram of the present utility model;

Fig. 2 be among Fig. 1 brush A to view.

As shown in the figure: in the one side that hair base 7 is not planted hair of planting of brush 1, have the groove 6 of 2-4 dark 4mm, wide 0.5mm, at unused state, brush 1 is into about 15 ° garden arc, when brush 1 stretches in the oral cavity, under the effect of oral cavity flesh, owing to plant hair base 7 bending within the specific limits, therefore bristle 5 deformables on the brush 1 are horizontal or reverse garden arc, with occlusal surface and the lingual surface that is adjacent to tooth, when brushing teeth, both can brush the outer surface of tooth like this, the also inner surface that can brush teeth, the corona that can also brush lower teeth simultaneously is partly.

Planting middle part, basic 7 back sides of hair, a protuberance is upwards arranged, ridge caves in inwards from the top, forms spherically mostly in brush depression hole 2, and the spherical button of brush holder 4 can freely rotate in depression hole 2, is only doing the time spent than external force greatly, and button just can come off out.This Hook's coupling relation between brush holder 4 and the brush 1 makes the user all handy from arbitrarily angled use.

Owing to adopt above-mentioned measure, realized the universal rotation of brush, bristle can be out of shape with the arrangement mode of oral cavity dens in dente tooth, bristle all can fit tightly at the interior outside and the occlusal surface of denture, the high outside and low outside toothpick that can replace of bristle is rejected clean with mailing thing in the teeth space, the outwash rate reaches or near 100%, prevented horizontal brushing teeth during tooth to gums and adamantine damage, reach the effect of massage gums, to children's denture is uneven prevention and therapeutic action arranged, various crowds' calculus dentalis and gums are had prevention and therapeutic action.

Claims (2)

1, a kind of toothbrush is made up of brush and brush holder, it is characterized in that: brush is 15 ° garden arc approximately; In the one side that Mao Jiwei plants hair of planting of brush, have the groove of 2-4 dark about 4mm at interval; Plant the one side middle part of hair planting Mao Jiwei, a protuberance is upwards arranged, ridge caves in inwards from the top, forms spherical depression holes mostly, and the diameter of the opening part in depression hole is less than the internal diameter in depression hole; The button of brush holder is spherical, and button can freely rotate in the depression hole, is Hook's coupling between brush holder and the brush.
