I hope it can help you and provide some reference directions for your product design. If you have the development needs of electric toothbrushes, you can trust us with confidence. We have rich experience in custom development of electronic products, can sell control boards and ICs, and can quickly quote the development costs and circuit board prices of electric toothbrushes, and provide reasonable prices. Design suggestions to help you develop good products with excellent user experience.

1. Functional requirements of electric toothbrush control board

1. Press the power button to turn on the power, and continue to press the power button to select different gears. Each gear corresponds to a different functional experience. When the desired gear is selected, the system will automatically lock the current gear after a pause of 3 seconds. After 2 minutes of brushing time, it will automatically turn off after brushing. During use, it will vibrate every 30 seconds. This reminder is to remind the user that it is time to change the brushing position. The toothbrush can be turned off at any time during use, and the above functions can be repeated when the power button is pressed again, and there will be a "beep-beep" prompt sound when it is turned off.

2. In order to meet different user experience during use, the adjustment of the swing strength is set for each gear, and the user can adjust the strength of the current gear according to the acceptable amplitude of brushing their teeth. The strength is divided into three modes: weak, medium and strong. For first-time users, it is recommended to use the lowest swing to adapt to the experience brought by the electric toothbrush as much as possible. When you can accept a stronger sense of amplitude, you can gradually increase the swing strength appropriately.

3. During the use of the toothbrush body, the dentist recommends that the pressing force of the bristles to the teeth is about 100 grams, and it is not recommended to press more than 100 grams. Excessive force will cause damage to the tooth surface and gums.

2. Instructions for use of electric toothbrush

Take out the toothbrush and gently insert the toothbrush head into the PTO shaft of the main body until there is a slight gap between the toothbrush head and the main body. At this time, you can turn on the power to test whether the toothbrush head is inserted correctly and whether the toothbrush is working normally. If it is normal, please turn off the power. Take a little toothpaste (can be used according to the user's personal habit) on the toothbrush head, put it in the mouth, and then press the power button to start brushing teeth. The swinging force of the toothbrush head will be weaker 3 seconds before starting the toothbrush each time to prevent the toothpaste from splashing, and the toothbrush will enter the normal swinging force after 3 seconds. After brushing your teeth, clean it and put it in a ventilated and dry place. Keeping it in a humid place for a long time will shorten the service life of the toothbrush and cause bacteria to grow on the toothbrush head. Not to mention soaking the toothbrush in water for a long time, which will not only breed bacteria, but also damage the service life of the toothbrush shell and dirt on the surface.

4.The charging method of the electric toothbrush circuit board

1. Charging method: Charge the main body through the wireless charging method of the charger. Generally, it takes about 12 hours to charge.

2. Charger: Power the charger through a 5V universal power adapter with USB output or a personal computer (computer).
