Abstract

Il s'agit d'une brosse à dent, je dirai, électronique à tête cylindrique, actionnée par un moteur à courant continue, son mode de fonctionnement repose sur la méthode de brossage dentaire dite « du rouleau» ; c'est-à-dire que la brosse doit toujours effectuer un mouvement rotatif continu de la gencive vers les dents. Ellecomprend un manche où sont rassemblés les principaux composants qu'on va décrire, et une tête cylindrique avec une partie travaillante (demi-cylindre) qui sera directement en vis-à-vis des dents pour en assurer le brossage, l'autre moitié du cylindre sera protégée par un écarteur en forme de demi-cylindre, destiné à protéger les muqueuses pendant le brossage son principe de fonctionnement met en oeuvre un système de gyroscope accéléromètre, capteur de température, (exemple un gy-521) qui mesure les angles formés par l'axe de la brosse par rapport au plan horizontal et transmet les valeurs à un microcontrôleur, véritable cerveau où sont stockées toutes les commandes, à son tour relié à un pont en h qui permet d'inverser le sens du courant délivré à un moteur à courant continu, qui lui est relié, suivant les angles. Elle comprend un bouton poussoir marche/arrêt que je nommerai bouton poussoir d'alimentation pour la 'mise sous tension, deux boutons (+) et (-) pour augmenter ou diminuer la vitesse de rotation de la brosse suivant la demande. Ces boutons sont reliés au microcontrôleur à qui ils transmettent des impulsions, et, par un programme informatique basé sur le principe de la pwm (pulse width modulation), permet d'accélérer ou de ralentir le moteur. Elle comprend aussi un bouton poussoir qui permet de basculer entre les modes haut et bas suivant l'arcade dentaire à brosser. Tout ceci est géré par un programme informatique supporté par le microcontrôleur (exemple un atmega 328p), le capteur de température permet éventuellement de couper le courant en cas de surchauffe, pour ce faire, on mettra ce composant le plus près possible du moteur pour que la mesure soit la plus fiable possible.It is about a toothbrush, I would say, electronic with cylindrical head, actuated by a motor with direct current, its mode of operation rests on the method of dental brushing known as "of the roller"; that is, the brush should always perform a continuous rotary motion from the gum to the teeth. It includes a handle where the main components that we are going to describe are gathered, and a cylindrical head with a working part (half-cylinder) which will be directly opposite the teeth to ensure brushing, the other half of the cylinder will be protected by a retractor in the shape of a half-cylinder, intended to protect the mucous membranes during brushing its operating principle uses a system of gyroscope accelerometer, temperature sensor, (example a gy-521) which measures the angles formed by the axis of the brush with respect to the horizontal plane and transmits the values to a microcontroller, a real brain where all the commands are stored, in turn connected to an h-bridge which makes it possible to reverse the direction of the current delivered to a DC motor, which is connected to it, at the angles. It includes an on / off push button that I will call the power push button for switching on, two buttons (+) and (-) to increase or decrease the speed of rotation of the brush according to the request. These buttons are connected to the microcontroller to which they transmit impulses, and, by a computer program based on the principle of pwm (pulse width modulation), makes it possible to speed up or slow down the motor. It also includes a push button that switches between high and low modes depending on the dental arch to be brushed. All this is managed by a computer program supported by the microcontroller (example an atmega 328p), the temperature sensor can possibly cut the current in the event of overheating, to do this, we will put this component as close as possible to the motor so that the measurement is as reliable as possible.
