Many people are using the electric toothbrush. After a period of time, the electric toothbrush can't be charged. What's the matter?
The reason why the electric toothbrush can not be charged
If the battery doesn't charge, the electric toothbrush still turns very slowly a few hours after charging, and then it stops. This shows that the battery of the electric toothbrush is broken. Generally, the battery is lithium battery, which is the same as that of the mobile phone. You can find the after-sales service for maintenance, or you can buy a lithium battery of the same specification at the place where the electric toothbrush is sold, or you can buy a new electric toothbrush.
Precautions for use of electric toothbrush
1. When charging the electric toothbrush, it's better to fully charge it at one time, instead of charging it for a few minutes, which will not cause damage to the electric toothbrush, but long-term use will affect the battery life.
2. When using the electric toothbrush, water may enter into it, so it's better to put it vertically in the brushing cup after brushing, and put it in a place with ventilation and sunshine to dry, so as to avoid battery damage, but it can't be exposed to the sun.
3. If possible, it's better to buy 2 or 3 toothbrushes at the same time for rotation, so as to prolong the drying time of toothbrush. This is especially important for people with gingivitis and periodontitis. In addition, rotation can also maintain the elasticity of toothbrush hair;
4. The old toothbrush with loose or curly bristles and lost elasticity must be replaced in time, otherwise it will be harmful to teeth and gums.
5. The toothbrush should be cleaned and disinfected once a week.
6. Do not share toothbrush with others to prevent mutual infection.
