Protect tooth brush head
Technical field
The present invention relates to toothbrush technology field, especially a kind of brush head on toothbrush.
Background technology
Existing brush head generally comprises the bristle that the setting on brush base is set, and the connection being connected with handle of brush base one end
Portion, the shape of bristle are typically all elongated cylinder, and top has plane or inclined, no matter uses what soft material
Material, all there are the corner angle at edge, long-time service at its top with teeth contact to damage dental surface, and the top of bristle
End is also undesirable to the massage effect of tooth also without elasticity.In addition the bristle of cylinder is elongated, is easily bent when brushing teeth, to
On motive force it is inadequate, it is poor to the cleaning action of tooth.
The content of the invention
Problem to be solved by this invention is to provide a kind of shield tooth brush head, and the flank of tooth is caused to hinder to solve existing toothbrush head
The problem of evil, the health care massage effect to tooth is poor.
To solve the above-mentioned problems, the technical scheme is that:What the setting that this shield tooth brush head includes on brush base was set
Bristle and the connecting portion being connected with handle of described brush base one end, the bristle include the brush body being connected with the brush base of lower part
With the brush ball at the top of the brush body, in lower small frustum upper greatly, the conical surface of the frustum concaves down arc-shaped, institute the brush body
Stating the height of brush body has difference, and the brush ball is hollow ball.
In the above-mentioned technical solutions, more specifically technical solution can also be:The brush radius of a ball at 0.18 millimeter extremely
In the range of 0.2 millimeter;The brush body and the brush ball are integrally formed for silica gel.
Further:The height of the brush body is different be divided to two kinds, the brush that multiple high brush bodies are formed arrange with it is multiple short
The brush body formed brush row be spaced apart.
By adopting the above-described technical solution, the present invention has the advantages that compared with prior art:
One brush ball of top design in bristle of this shield tooth brush head, makes bristle stronger to the brushing force of tooth, while disappear again
Except the corner angle of conventional bristles top surface, long-time service avoids the injury to tooth;Brush ball makes hollow ball, can make brush ball
Produce larger elasticity at brush knob face, play the role of massage gum, along with by the height of brush body be designed to height not
Deng more preferably can massaging and clean between cog gap;The brush body part of bristle is designed to the frustum of special shape, makes brush body not
It is easily bent, can effectively promotes brush ball to clean tooth, from substantially solves the problem of cleaning of teeth effect is poor.
Brief description of the drawings
Fig. 1 is the front view of the embodiment of the present invention.
Embodiment
The embodiment of the present invention is described in further detail below in conjunction with the accompanying drawings:
Shield tooth brush head as shown in Figure 1, it include brush base 2 on setting set bristle 3, and 2 one end of brush base and hand
The connecting portion 1 of handle connection, bristle include the brush ball 3-2 at the top of the brush body 3-1 being connected with brush base 2 and brush body 3-1 of lower part, make brush
The brushing force of 3 pairs of teeth of hair is strong, while eliminates the corner angle of conventional bristles top surface again, and long-time service avoids the injury to tooth.
Brush ball 3-2 is hollow ball, and brush ball can be made to produce larger elasticity at brush knob face, plays the role of massaging gum, brush ball
3-2 radiuses r=0.18 millimeter.In lower small frustum upper greatly, the conical surface of frustum concaves down arc-shaped brush body 3-1, makes brush body 3-1
Do not allow flexible, can effectively promote brush ball 3-2 to clean tooth, from substantially solving cleaning of teeth effect difference
Problem.Brush body 3-1 and brush ball 3-2 are integrally formed for silica gel, reduce the probability that brush ball 3-2 is broken from brush body 3-1.Brush body 3-
1 height is different to be divided to two kinds, the brush row interval point that the brush row that multiple high brush body 3-1 are formed is formed with multiple short brush body 3-1
Cloth, more preferably can massage and clean between cog gap.
