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.

Refer to fig. 1, 2 and 3 for the overall structure of the present invention.

The utility model provides a toothbrush head structure, including toothbrush headstock 1, substrate 2, central bristle tuft 3, a plurality of peripheral bristle tufts 4.

The central bristle cluster 3 is in the shape of circle or ellipse, and is located at the center of the brush surface of the toothbrush head. The center bristle tufts 3 preferably have a diameter in the range of 4.4 to 5.2 mm.

The peripheral bristle tufts 4 are divided into front tuft bristles 41, rear tuft bristles 42, left side tuft bristles 43, right side tuft bristles 44 and four inclined tuft bristles 45 which are symmetrically distributed, the four inclined tuft bristles 45 are respectively arranged between the left side tuft bristles 43 and the right side tuft bristles 44 and the front tuft bristles 41 and the rear tuft bristles 42, and intervals are formed among the tufts of bristles to form flower-shaped distribution. The preferable range of each interval is 0.8 to 1.2 mm.

As shown in fig. 4, the overall brush face of the peripheral bristle tufts 4 has a concave surface 46 facing the central bristle tuft 3, the apex of the central bristle tuft 3 projecting out of the concave surface 46 and forming an arcuate top surface 31.

More preferably, the top arcuate surface 31 of the center bristle tuft tip protrudes 1 to 2mm, preferably 1.4 to 1.6mm, beyond the inner edge of the concave surface 46.

As shown in FIG. 5, the front tuft bristles 41 and the rear tuft bristles 42 are in fan-shaped structures, the cross-sectional shapes of the front tuft bristles 41, the rear tuft bristles 42, the left tuft bristles 43, the right tuft bristles 44 and the four inclined tuft bristles 45 are changed from small to large from inside to outside, and the intervals between the front tuft bristles 41 and the rear tuft bristles 42 form a central radial shape.

The preferable range of the width of the tail ends of the front tuft bristles 41 and the rear tuft bristles 42 is 4.8-5.4 mm, and the length is 5.8-6.2 mm.

The left side tuft brush hair 43 and the right side tuft brush hair 44 are arranged in a longitudinal strip shape in the length direction of the toothbrush, the length of the longitudinal strip shape is defined as being larger than the width, in the embodiment, the preferred range of the length is 5.3-5.8 mm, and the preferred range of the width is 1.8-2.8 mm.

It should be noted that the central bristle tuft 3, the front bristle tuft 41, the rear bristle tuft 42, the left side bristle tuft 43, the right side bristle tuft 44, and the four inclined bristle tufts 45 are all formed by densely packing bristles, the diameter of the peripheral bristle tuft 4 is preferably 0.12, and the diameter of the central bristle tuft 3 is preferably 0.15, so as to make the bristles of the central bristle tuft 3 harder and more elastic than those of the peripheral bristle tuft 4, and have higher cleaning power, thereby achieving the effect of polishing the tooth surface.

Referring to fig. 1 and 2, the substrate 2 of the embodiment of the present invention has a plurality of holes 21 passing through the central bristle tufts 3 and the peripheral bristle tufts 4, the back of the substrate 2 forms a concave portion 22 within the range of the holes 21, the central bristle tufts 3 and the peripheral bristle tufts 4 pass through the corresponding holes 21, and a melted layer 23 disposed in the concave portion 22 is formed on the back, so that each bristle tuft is fixedly connected to the substrate 2.

The toothbrush head seat 1 is provided with a cavity 11, the substrate 2 can be matched and placed in the cavity 11, and the two are fixedly connected through ultrasonic welding.

Preferably, in order to form a more reliable connection structure between the toothbrush head holder 1 and the substrate 2, the back edge of the substrate 2 has a first step edge 24, and the toothbrush head holder 1 is provided with a second step edge 12 corresponding to the shape of the step edge.

Use the utility model discloses when carrying out the oral cavity cleanness, the superfine brush hair of peripheral bristle group 4 passes through concave surface 46's transition deformation, make the periphery can contact the gum, and whole can contact and clean, and because central bristle group 3 is higher than concave surface 46's interior edge then strengthen the polishing to the flank of tooth, front and back front tuft brush hair 41, back tuft brush hair 42 area of contact is big, can enter the oral cavity corner degree of depth clean, can also improve holistic cleaning ability, through the interval between each tuft brush hair, can make the residue discharge fast, and can bubble merrily and lightheartedly, clean effect is more excellent.
