Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings.

As shown in figure 1, the utility model discloses a toothbrush head of self-adaptation adjustment angle, included toothbrush head frame 1, brush hair base plate 2, elastic backboard 3, wherein, brush hair base plate 2 surface is provided with brush hair 21, its mode of setting adopt the common technology in toothbrush field can, brush hair base plate 2's shape is equivalent with toothbrush head frame 1's shape for brush hair base plate 2 can overlap in toothbrush head frame 1, and brush hair base plate 2 size is less than toothbrush head frame 1, makes to have clearance 4 between the two like this.

The elastic back plate 3 is integrally arranged on the back of the toothbrush head frame 1, and the elastic back plate 3 is made of elastomer materials such as rubber or silica gel materials, so that the whole body has deformation capability.

Referring to fig. 2 and 3, the elastic back plate 3 has a middle fixing portion 31 and upper and lower connecting

portions

32 and 33, the bristle base plate 2 is fixedly disposed on the fixing portion 31, and the upper and lower connecting

portions

32 and 33 are fixedly connected to the corresponding upper and lower positions of the back surface of the toothbrush head frame 1.

With the above structure, a gap 41 is left between both sides of the fixing portion 31 and the toothbrush head frame 1, so that the whole of the bristle base plate 2 and the fixing portion 31 can swing left and right at a certain angle by the soft characteristics of the upper and lower connecting

portions

32, 33, and more preferably, the shapes of both sides of the fixing portion are matched with those of both sides of the bristle base plate.

When the elasticity of the elastic back plate 3 is good enough, the swinging change adjustment of the brush hair base plate 2 in a certain range from up to down and back to front can be realized.

It should be noted that the utility model uses the vertical direction and the length direction of the toothbrush head as the upper and lower directions, the surface of the brush hair base plate 2 is provided with the brush hair, and the other surfaces are estimated according to the definition.
