As an improvement to the present invention, the length of the resilient hardware extends from the interior of the brush neck to the interior of the brush handle.

As right the utility model discloses an improve, keeping away from of elasticity hardware the one end of planting the hair panel is equipped with bends, bend and collude in the draw-in groove.

As an improvement of the utility model, the free end of the brush handle is provided with a shaft hole matched with the output shaft of the electric toothbrush driver.

As an improvement of the utility model, the brush handle, the brush neck and the flocking panel are made of plastic PP or PP plastic physical properties.

As an improvement of the utility model, the brush handle, the brush neck and the hair planting panel are coated with soft rubber.

As an improvement of the invention, the thickness H2 of the brush neck and the flocked panel corresponding to the part below the elastic hardware is selected between 0.3 and 3.0 mm.

As an improvement of the utility model, the depth H1 of the groove is larger than two parts of the thickness H of the flocked panel above the elastic hardware.

As an improvement, the elastic hardware is made of stainless steel or copper.

The utility model discloses owing to adopted the width direction along the flocking panel is equipped with the recess of a plurality of interval predetermined distances on the flocking panel, and at least the inside of flocking panel is equipped with the structure of elasticity hardware, makes the utility model has the advantages of the effect of brushing teeth is better to can realize crooked angle of going to be fit for having brushed teeth certainly along with user's hard when using, can clear away tooth arc position dirt effectively.

Detailed Description

In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1 to 4, fig. 1 to 4 show a deformable toothbrush head, which comprises a brush handle 1, a brush neck 2 and a bristle-implanted panel 3 connected in sequence, bristles 31 are arranged on the bristle-implanted panel 3, an elastic hardware 4 is arranged inside the brush handle 1, the brush neck 2 and the bristle-implanted panel 3 and extends into the brush handle 1 through the brush neck 2, a plurality of grooves 32 (in the embodiment, the grooves 32 are 4, but the grooves 32 can be selected from 1 to 6 according to the requirement) are arranged on the bristle-implanted panel 3 at predetermined intervals along the width direction of the bristle-implanted panel 3, and the depth H1 of the groove 32 is preferably greater than two parts of the thickness H of the bristle-implanted panel above the elastic hardware. In one embodiment of the present invention, the brush handle 1, the brush neck 2 and the bristle-implanted panel 3 may be made of the same material, such as PP plastic. In another embodiment of the present invention, a part of the brush handle 1, the brush neck 2 and the hair-planted panel 3 can be made of PP plastic or a material having physical properties of PP plastic, such as nylon material, and then at least the brush neck 2 and the back of the hair-planted panel 3 are covered with the soft rubber 5 (see fig. 4). In the third embodiment of the present invention, the brush neck 2 and the part of the bristle plate 3 away from the bristles 31 are made of soft rubber 5. The soft rubber 5 can adopt TPE, TPR or TPU.

Preferably, the length of the elastic fitting 4 is at least greater than the length of the flocked panel 3. Preferably, the length of the resilient fitting 4 extends to the handle 1. Preferably, the length of the elastic fitting 4 extends to the brush neck 2.

Preferably, the keeping away from of elasticity hardware 4 the one end of flocking panel 3 is equipped with bend 41, bend 41 colludes in draw-in groove 11, can prevent elasticity hardware 4 axial displacement.

Preferably, a shaft hole 12 matched with an output shaft of the electric toothbrush driver is arranged at the free end of the brush handle 1.

Preferably, the thickness H2 of the brush neck 2 and the bristle panel 3 below the elastic fitting 4 is selected between 0.3 and 3.0 m.

Preferably, the elastic hardware 4 can be made of stainless steel or copper sheets.

Fig. 5 is a schematic view of a use state of the embodiment shown in fig. 1. The condition shown in fig. 5 facilitates better brushing of the interior of the upper row of teeth.
