Embodiment Construction

[0015] Preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0016] figure 1 , figure 2 , image 3 , Figure 4 It is a structural view of toothbrush bristles in the prior art, showing a "one"-shaped plane on the end face of the bristle array, and a concave arc, wave, and zigzag surface.

[0017] Figure 5 It is an embodiment of the present invention. In the toothbrush bristle array structure with long rows and short columns, the center column is empty, and two symmetrical bristle arrays are distributed. All the bristles are formed with equal lengths, forming a "one" shape. flat.

[0018] Figure 6 It is another embodiment of the present invention. The bristles arranged from the two ends of the long row to the empty rows in the center are shortened successively, and the end faces of the bristles are formed into a "V"-shaped slope through cutting or injection molding. The included angle of the "V" shape is...

Abstract

The invention discloses brush hairs of a toothbrush. The brush hairs consist of two brush hair arrays, in an array structure that the long sides are configured as lines and the short sides are configured as columns, the central column is hollow, and the end surfaces of the two arrays are made into horizontal-lined planes, V-shaped inclined surfaces and V-shaped stepped surfaces, so that the brushhair arrays can form more contact surfaces which are in contact with teeth, so that the brush hairs can be more adhered with the teeth, and because of uniform stress, skewing and curling caused by stronger stress formed in the central column of the long lines of the brush hairs are reduced; moreover, the teeth can be cleaned more comfortably and high-effectively. The invention also discloses a manufacturing method of a brush hair mould and a brush hair molding method.

Description

technical field [0001] The invention relates to a toothbrush, in particular to a bristle of the toothbrush, a method for manufacturing a bristle mould, and a method for forming the bristle. Background technique [0002] The bristles of manual and electric toothbrushes on the market are all in one piece array structure in rows and columns. The end face of the bristle array is mostly a "one"-shaped plane, or a concave arc, or a wave shape, or a zigzag shape. In these structures, the contact surfaces between the bristles and the teeth are relatively few, and the center column of the long row of toothbrush bristles bears a heavier force, which is easily crooked and curled. Contents of the invention [0003] The purpose of the present invention is to provide a toothbrush bristle and a method for manufacturing a bristle mold and a bristle forming method that can form more contact surfaces with the teeth, fit the teeth more, apply force evenly, and last. [0004] In order to ac...
