Fig. 3 A to Fig. 3 E show toothbrush head according to another embodiment of the invention.In this embodiment, head 10 Including being adjacent to the proximal section 16 of shank 12 and being away from the distal section 18 of shank 12.Proximal section 16 and distal region Section 18 is tied by flexible bridge portion 20.In an illustrated embodiment, the longitudinal axis X-X substantial registration of distal section 18 In the longitudinal axis Y-Y of proximal section 16.Proximal section 16 and distal section 18 respectively have in the longitudinal direction perpendicular to head 10 The straight linear edge that the side of axis upwardly extends, the wherein straight linear edge 48 of distal section 18 are in face of proximal section 16 Straight linear edge 50.The straight linear edge 48 of distal section 18 is couple to the straight line of proximal section 16 by flexible bridge portion 20 Property edge 50 so that distal section 18 can be flexible mobile (as shown in Figure 3D) relative to proximal section 16.The length of distal section 18 Degree and the ratio of the length of proximal section 16 are about 1: 1.3, and distal section 18 has the length of 11.6mm, and proximal section 16 Length with 15.4mm.The overall length on head 10 is 30.1mm.Distal section 18 has the width of 9.3mm, and proximal section 16 width with 10.7mm.
Flexible bridge portion 20 still further comprises the flexible cleaning elements 26 extended from the first face 14, this flexible cleaning elements 26 extend along in the flexible bridge portion 20 on the direction of the longitudinal axis on head 10.
Flexible cleaning elements 26 are the elastic walls extended along flexible bridge portion with straight, linear configuration, and have and be away from The distal side edge in the first face.The elastic wall include from distal side edge towards the height of 14 elasticity of extension wall of the first face about 6/8 away from From notch 28.
Proximal section 16 and distal section 18 are formed by polypropylene, and the bridge that flexible bridge portion is formed including the use of polypropylene Connect section 30.Proximal section 16 is attached to distal section 18 by bridge section, and between the first face 14 and the second face 32.The Two faces 32 include tissue cleaner part 44.Flexible bridge portion 20 still further comprises the elastic material for surrounding bridge section 30, and And tissue cleaner part 44 and flexible bridge portion 20 are integral.Tissue cleaner part 44 includes multiple tubercles 46.
Proximal section 16 includes more than the first a cleaning elements 34 extended from the first face 14, and distal section 18 include from More than second a cleaning elements 36 that first face 14 extends.A cleaning element 34 more than first and more than second a cleaning elements 36 include gradually Sharp bristle, the tapered bristles cluster enter square brush tuft hole 38, these bristle cluster holes have the size of 1.40mm × 1.40mm.The A cleaning element 34 more than one has the height of the height equal to more than second a cleaning elements 36.Head 10 includes square brush tuft hole 38, these bristle cluster holes are oriented the grid arrangement of columns and rows (as above for figure in proximal section 16 and distal section 18 Bristle cluster hole 38 in 2A to Fig. 2 F is arranged described).Distal section 18 includes 38 farthest skidding 40 of bristle cluster hole, and proximal region Section 16 includes bristle cluster hole recent side row 42, wherein in farthest skidding 40 and nearest skidding 42, bristle cluster hole 38 is relative to row Offset (is as above arranged for the bristle cluster hole 38 in Fig. 2A to Fig. 2 F described).
Flexible cleaning elements 26 have the height less than more than 34 and second a cleaning element 36 of more than first a cleaning elements Highly.
On the one hand, the present invention provides a kind of oral care implement including head 10 and shank 12, head 10 includes First face 14 and multiple cleaning elements, these cleaning elements extend from the first face 14.Head 10 includes being adjacent to the close of shank 12 Distal section 18 is couple to closely by lateral areas section 16, the distal section 18 for being away from shank 12 and flexible bridge portion 20, flexible bridge portion Lateral areas section 16 so that distal section 18 can be flexible mobile relative to proximal section 16.Flexible bridge portion 20 still further comprises at least One flexible cleaning elements 26, at least one flexible cleaning elements extend from the first face 14.At least one flexible cleaning elements 26 Extend along in the flexible bridge portion 20 on the direction of the longitudinal axis on head 10.Flexible cleaning elements 26 play polishing tooth The effect of tooth surface and cleaning tooth.
Using oral care implement during, flexible bridge portion 20 allow distal section 18 relative to proximal section 16 forward With move backward, to allow oral care implement to go deep into oral cavity, to clean back teeth.This flexibility also reduces or prevents When brushing teeth, transitional pressure is applied to back teeth.
In some embodiments, the longitudinal axis X-X of distal section 18 is inclined relative to the longitudinal axis Y-Y of proximal section 16 Tiltedly at from 8 ° to 15 °, from 9 ° to 14 °, from 10 ° to 13 ° or about 13 ° of angle [alpha].In these embodiments, work as dental treatment When tool is in stressless state, that is, so that distal section 18 is moved relative to proximal section 16 when not exerting a force to this utensil When dynamic (such as when this utensil is not used by), the longitudinal direction of the longitudinal axis X-X of distal section 18 relative to proximal section 16 Axis Y-Y is inclined to the angle higher than angle [alpha].When exerting a force in use, distal section 18 can be relative to proximal section 16 movements, but once remove any exerted forces, its initial position is returned into, axis X-X is relative to axis at this time The obliquely-angled α of line Y-Y.The longitudinal axis X-X of distal section is obliquely-angled relative to the longitudinal axis Y-Y of proximal section 16 α allows head to be fitted tooth curve, and flexible bridge portion allows head to adapt to dental surface profile.
