If the electric toothbrush is used for a long time, it may be damaged. How to disassemble and repair the electric toothbrush? The disassembly and maintenance methods of electric toothbrush are as follows:
1. Poke open from the bottom of the electric toothbrush, use a flat knife to insert into the charging port of the toothbrush base, and pull it out while turning it to the left, so that the toothbrush sealing cover will be pulled out.
2. Generally, there will be a fixed screw at the bottom. After unscrewing it, you can open the back cover and pull out the internal components of the toothbrush. Or remove the toothbrush head, press it down, and it will come out.
3. If the more you press down on the brush head, the weaker it becomes, and the stronger the vibration when you pull the toothbrush head up, then it is the problem of the gap between the magnets. There is a screw behind the red coil. After removing the screw, pull down the red coil to leave enough space between it and the magnet. Then tighten the screw to fix it and reassemble the toothbrush.
