Description

Toothbrush Technical Field The utility model relates to the technical field of oral cavity cleaning tools, in particular to a toothbrush. Background The dense toothbrush can reduce the pressure of the toothbrush to gum when brushing teeth, thereby improving the comfort of brushing teeth, and the area occupied ratio of the implanted pores in the whole toothbrush head can be improved by reducing the interval between the implanted pores, thereby improving the density of the bristle bundles, and forming the dense toothbrush, however, the implanted pores of the current toothbrush are round holes, the distances from the arc edges of the implanted pores to the arc edges of the adjacent implanted pores are unequal, so that more space between the implanted pores and the implanted pores can not be utilized, and the density of the bristle bundles can not be further improved. Disclosure of utility model The utility model aims to provide a toothbrush, which solves the problem that more space between implanted pores and implanted pores of the existing toothbrush can not be utilized due to the fact that the implanted pores are round holes. In order to solve the problems, the utility model provides the following technical scheme: The utility model provides a toothbrush, includes toothbrush head and toothbrush handle, toothbrush head includes the base plate, one side of base plate is equipped with a plurality of and plants the pore, it is square to plant the cross-section of pore, every plant the pore the length with adjacent plant the length parallel and the alignment of pore, it is 2.2mm ~3.2mm to plant the length of pore, it is adjacent on the length direction of base plate plant the minimum interval of pore and be greater than or equal to 0.8mm, it is adjacent on the width direction of base plate plant the minimum interval of pore and be greater than or equal to 0.5mm. According to the toothbrush, the metal sheet used for fixing the bristle bundles is arranged in the implanted holes, an included angle formed by the length direction of the metal sheet and the length direction of the substrate is 5-30 degrees, and the length of the metal sheet is greater than the side length of the implanted holes by +0.5mm. In the toothbrush, an included angle formed between the length direction of the metal sheet and the length direction of the base plate is 15 degrees, the side length of the implanted hole is 2.7mm, and the length of the metal sheet is more than 3.2mm.
