Detailed Description

The following description provides many different embodiments, or examples, for implementing different features of the invention. The particular examples set forth below are illustrative only and are not intended to be limiting.

Referring to fig. 1 and 4, an object of the present invention is to provide a toothbrush head 10, including a fixing portion 101 and a cleaning portion 102, wherein one end of the cleaning portion 102 is fixedly disposed on the fixing portion 101, referring to fig. 1 and 2, the cleaning portion 102 includes a first hair cluster 11, a second hair cluster 12 and a third hair cluster 13, the first hair cluster 11 is disposed on the toothbrush head 10 in a row along a length direction of the fixing portion 101, and the second hair cluster 12 and the third hair cluster 13 are sequentially disposed in a row from the first hair cluster 11 to two sides; specifically, the second bristle tufts 12 and the third bristle tufts 13 may be symmetrically disposed on both sides of the first bristle tufts 11, and in other embodiments, the second bristle tufts 12 and the third bristle tufts 13 may be asymmetrically disposed, and the first bristle tufts 11, the second bristle tufts 12 and the third bristle tufts 13 are disposed in a row, but it should be noted that the arrangement in a row means that the first bristle tufts are integrally arranged in a row, and includes the case that the center of each bristle tuft is on a straight line and on a non-straight line, such as a straight line in a shape of a Chinese character "yi", and may also be in a wavy line, a zigzag line, and the like, which are arranged in a row as a whole.

Referring to fig. 2, the first tufts 11 and the third tufts 13 have a smaller diameter than the second tufts 12. Specifically, the first, second and third tufts 11, 12 and 13 are fixed to the fixing portion 101 by a plurality of tufts of bristles made of a relatively stiff nylon material, the bristles having a cross-section of any one of a circular, rectangular, oval, triangular or polygonal shape and a cross-sectional diameter of about 0.006-0.007 inches. More specifically, the first tufts 11 and the second tufts 12 employ a stiffer nylon material relative to the third tufts 13 as the primary cleaning function.

As shown in connection with fig. 3, the second tufts 12 are cylindrical, and in a preferred embodiment, the second tufts 12 are any one of cylindrical, prismatic, or elliptically cylindrical; the end face of the cylindrical bristle cluster is provided with an arc-shaped recess 121, so that the end face of the cylindrical bristle cluster is convenient to wrap and attach to an arc-shaped structure of a tooth surface, and the tooth surface, a pit ditch and dental plaque in a spot gap can be cleaned conveniently; preferably, the arc-shaped recess 121 is a spherical surface, an ellipse, or a convex curve with various arcs.

As shown in FIG. 1, the end surface of the cleaning portion 102 is curved along the length of the head 10. The arc-shaped structure is beneficial to deep cleaning in the fossa sulcus and the far and middle blind pocket of young permanent teeth, and the cleaning efficiency is increased.

Similarly, as shown in fig. 3, the end face of the cleaning portion 102 is curved along the width direction of the brush head 10, and finally forms a central protrusion which gradually decreases toward the periphery, so as to contribute to the secondary cleaning function of the third bristle set, and the primary cleaning function of the first bristle set 11 and the second bristle set 12.

Further, as shown in connection with FIG. 3, the first tufts 11 and the third tufts 13 are tapered tufts; it should be noted that the third bristle group 13 is the shortest one, and is located at the edge of the toothbrush head 10, so that the toothbrush will not contact the tooth surface but will contact the gum tissue frequently when in use, and the bristle is made of a softer nylon material than the first bristle group 11 and the second bristle group 12 for the purpose of protecting and properly massaging the gum tissue.

As shown in fig. 1, the first tufts 11 comprise tufts of various length dimensions, which are arranged with a middle length and gradually decreasing toward both ends along the arrangement direction of the first tufts 11; specifically, the tufts with different lengths can well penetrate into the fissure of young permanent teeth for cleaning, wherein the difference between the long tufts 111 and the middle tufts 112 is about 1-2 mm; the difference between the medium tufts 112 and the short tufts 113 is about 1-2 mm; the difference between the tufts 113 and the third tufts 13 is about 0 mm to about 1 mm, although other variations are possible. The protruding part in the middle can clean the interdental space more easily during the process of brushing teeth along the interdental space.

Preferably, the first, second and third tufts 11, 12 and 13 are each composed of bristles having any one of a circular, rectangular, oval, triangular or polygonal cross-section.

Referring to fig. 4, the present invention further provides a toothbrush, which comprises the above-mentioned brush head 10 and the above-mentioned brush handle 20, wherein the brush head 10 is detachably or integrally and fixedly mounted on the brush handle 20.

Preferably, please refer to fig. 4, the brush holder is disposed at an angle, and the end of the brush holder 20 is connected to the brush head 10, the brush holder is disposed in an L shape, so that an operator can directly place the brush head 10 into a blind pocket of a young permanent tooth for cleaning, and the brush head 10 can be used for cleaning the blind pocket of the young permanent tooth with a good cleaning effect, while the conventional straight-handle toothbrush cannot place the brush head 10 into the blind pocket of the young permanent tooth, so that the blind pocket cannot be cleaned with a good or difficult purpose, thereby causing dental plaque and food residue to be retained and causing caries and inflammation of gums. For better cleaning effect, the middle bristles 14 have a triangular cross section, the peripheral bristles 15 have a circular cross section, the ends of the middle bristles 14 are sharp needles, and the ends of the outer peripheral bristles 15 are round-headed, as shown in fig. 5 and 6.

Preferably, the brush handle 20 is provided with anti-slip portions on both left and right sides and front and rear sides. Specifically, the surface of the brush handle 20 is designed to be granular and non-slip, and is made of silica gel, so that the toothbrush is beneficial to holding and not easy to slip, and meanwhile, the toothbrush is convenient to control the force and the angle during holding, and the tooth brushing efficiency is improved.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
