Embodiment Construction

[0034] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0035] like figure 1 As shown, it is a schematic diagram of the position division of teeth. Humans have two rows of teeth, upper and lower. Each row of teeth is divided into three surfaces: inner surface, outer surface, and occlusal surface. Each surface can be divided into three positions: left, right, and front , 2*3*3=18 positions in total. The rotation direction of the brush head is closely related to the brushing position. You can add sensors to the toothbrush to obtain surrounding information, and then distinguish the current brushing position according to the acquired information and the characteristics of each position, and then control the rotation direction of the brush head so that it is in line with the gums. The direction of growth i...

Abstract

The invention discloses a method for judging the movement direction of a brush head according to the angular velocity of a toothbrush, and relates to the fields of toothbrushes. The method comprises the steps that the angular speeds in the X axis direction of the toothbrush and the angular speeds in the Z axis direction of the toothbrush are obtained; an accumulated value of the angular speeds in the X axis direction of the toothbrush and an accumulated value of the angular speeds in the Z axis direction of the toothbrush are judged through an X-axis angular speed accumulator and a Z-axis angular speed accumulator respectively; the rotating direction of the brush head is judged through a static state judging counter. According to the method, the angular speed changes of the toothbrush are acquired by arranging angular speed sensors in the toothbrush, the angular speed changes when the toothbrush moves to another position from one position, therefore, the movement direction of the toothbrush can be judged through the angular speed values acquired by the angular sensors, and then the next position to be brushed is judged according to the movement direction.

Description

technical field [0001] The invention relates to the field of toothbrushes, in particular to a method for judging the moving direction of a brush head according to the angular velocity of the toothbrush. Background technique [0002] The up-and-down vibrating and back-and-forth rotating electric toothbrushes that are currently commonly used clean teeth through the high-speed reciprocating motion of the bristles. If the force is too large, it is easy to damage the gums. An electric toothbrush with a 360-degree rotating brush head. When brushing teeth, the brush head rotates in one direction along the growth direction of the gums, without harming the gums. The rotation direction of the brush head of this kind of toothbrush is closely related to the brushing position. If the user needs to control the rotation direction of the brush head according to the brushing position, it will cause extremely inconvenient use. Therefore, automatically judging the position of brushing teeth a...
