Motion state judging assembly and toothbrush

Abstract

The invention provides a motion state judging assembly and a toothbrush, and relates to the field of toothbrush. The assembly comprises at least one switch assembly and a signal processing circuit. The switch assembly comprises a receiving cavity, a ball and a switch pin. The ball is received in the receiving cavity and can move in the receiving cavity. A switch pin is arranged on that accommodating cavity, and the ball can trig the switch pin during the movement. The signal processing circuit is connected to the switch pins of the switch assembly to convert the triggered state of the switch pins into an electrical signal. Compared with the prior art, the motion state judging component provided by the invention has simple structure, and reduces the processing process requirements and processing cost. There is no need to re-calibrate the ball after welding, the welding point is far away from the ball, and the generated tension will not affect the movement of the ball, so the calibrationprocess can be canceled, the production time is shortened, and the defect rate caused by the wrong calibration is reduced.

Description

Technical field [0001] The invention relates to the field of toothbrushes, in particular to a motion state judgment component and a toothbrush. Background technique [0002] The toothbrush needs to perform complex movements in the oral cavity when cleaning the teeth. The correct brushing posture can ensure that the bristles touch the surface of each tooth and between the teeth. Through reciprocating friction and squeezing, the debris can be brushed away from the oral cavity as much as possible The attachment surface can clean the oral cavity more efficiently, maintain oral hygiene and ensure human health. Incorrect brushing posture will cause debris to remain in the oral cavity, reducing the cleaning effect of brushing. In the long term, it will not only affect the smell of the mouth, but also damage the surface structure of the teeth and cause symptoms of gum pain and bleeding. [0003] In order to ensure that the user adopts the correct brushing posture when brushing his teeth, ...
