For achieving the above object, the utility model uses following technical scheme.

The utility model provides a kind of toothbrush, including brush head and brush handle, and the brush head is connect with brush handle by a segmental arc, The side of the brush head is implanted with bristle, the brush head to another lateral bend for deviating from the bristle, and the brush head with it is described The radian of segmental arc is tangent.

Preferably, the segmental arc is integrally arc-shaped, the brush head be also bent it is in the arc-shaped, and the segmental arc where Diameter of a circle is identical as diameter of a circle where the brush head.

Preferably, diameter of a circle where the brush head is 500~600mm.

Preferably, the length of the segmental arc and the brush head accounts for the 40%~45% of toothbrush total length.

Preferably, the length of the segmental arc and the brush head is 80~85mm.

Preferably, the length of the brush handle is 100~120mm.

Preferably, the brush handle is staight shank.

Preferably, the angle of the tangential direction of the brush handle and the brush head ends is 23~25 degree.

Preferably, the length of the brush handle is 110mm, and the sum of the brush head and the length of segmental arc are 83.5mm, described The angle of the tangential direction of brush handle and the brush head ends is 23.5 degree.

Preferably, the brush handle is cylindrical, and diameter is 10~12mm.

The toothbrush of the utility model is connect by a segmental arc with brush handle using by brush head, and makes brush head to away from bristle Another lateral bend, it is convenient and using comfortable effect to reach gripping and the technical solution for keeping the radian of brush head and segmental arc tangent Fruit.

Detailed description of the invention

Fig. 1 is the overall structure diagram brushed teeth in the present embodiment；

Fig. 2 is the example of size figure brushed teeth in the present embodiment.

Specific embodiment

With reference to the accompanying drawing and specific embodiment is described further.

Shown in referring to Fig.1, the present embodiment provides a kind of toothbrushes 100, are primarily adapted for adult use, it includes brush head 10 and brush Handle 20, the brush head 10 are connect with brush handle 20 by a segmental arc 30, and the side of the brush head 10 is implanted with bristle 40, the brush First 10 to another lateral bend for deviating from the bristle 40, and the brush head 10 and the radian of the segmental arc 30 are tangent.

It is preferred that one of, the segmental arc 30 is whole to be arc-shaped, the brush head 10 be also bent it is in the arc-shaped, and The 30 place diameter of a circle of segmental arc is identical as the 10 place diameter of a circle of brush head.

Referring to shown in Fig. 2, for convenient for gripping, the toothbrush of the present embodiment, the radius R of circle where brush head 10 or segmental arc 30 For 250~300mm, i.e. diameter is 500~600mm.

Meanwhile above-mentioned segmental arc 30 accounts for the 40%~45% of 100 total length of toothbrush with the sum of the length of the brush head 10 L1, The sum of the length of the segmental arc 30 of the present embodiment and the brush head 10 L1 is 80~85mm, the length L2 of brush handle 20 is 100~ 120mm.Preferably, the length of the brush handle 20 is L2=110mm, the sum of the brush head 10 and the length of segmental arc 30 are L1 =83.5mm.Above-mentioned brush handle 20 can be fabricated to staight shank, at this point, the total length of toothbrush 100 is 183.5~205mm, reach just single Hand is held and optimal comfort level.

In addition, above-mentioned brush handle 20 and the angle design α of the tangential direction of 10 end of brush head are 23~25 degree, preferably α= 23.5 degree, in this way, brush head 10 can be protruded into oral cavity everywhere by normal hold when brushing teeth, convenient for the various of cleaning tooth Corner.

Meanwhile the brush handle is cylindrical, diameter is 10~12mm, preferably 11mm, and the fineness is rigid It is good to be suitable for holding.

The present embodiment also brush handle 20 lower end design have wedge shape tip 21, and 21 on the point at be provided with for hanging Circular hole 22, wherein tip 21 convenient for reduce 100 lower end of toothbrush and tooth bottom of a cup portion contact area, the mouldy raw bacterium of waterproof, circular hole 22 dry on the components such as hook for hanging over toothbrush 100.

In conclusion the toothbrush of the utility model, connect by a segmental arc with brush handle using by brush head, and make brush head to Away from another lateral bend of bristle, and the technical solution for keeping the radian of brush head and segmental arc tangent, it is ground in conjunction with by repeatedly practice Study carefully reasonable size out, reach gripping conveniently and uses comfortable effect.

Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited In contradiction, all should be considered as described in this specification.

Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed, But it cannot be understood as the limitations to utility model patent range.It should be pointed out that for the common skill of this field For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to The protection scope of the utility model.
