Panasonic is one of the largest manufacturers of electronic products in the world, and its brand slogan is "Life is full of creativity". Panasonic electric toothbrush has the characteristics of high cost performance and Japanese products. Panasonic is a Japanese brand, and its product quality is quite good, especially its product line is rich, covering all kinds of household appliances and personal care products. Panasonic electric toothbrush adopts soft bristles with a height difference of 3mm, which can minimize the damage to gums and protect oral health when cleaning teeth.

Panasonic uses soft bristles with a tip of 0.02 mm, which is much better than those very hard ordinary bristles. Especially for users in dentine hypersensitivity, the softness of bristles is very important. There are also two kinds of brush heads, one is the brush head used under ordinary circumstances, which is basically suitable for the conventional mode. The other is a brush head for dentine hypersensitivity users, which can be applied to sensitive mode.

Working principle of electric toothbrush

Working principle of rotary electric toothbrush: the principle of rotary electric toothbrush is relatively simple, that is, the motor drives the circular brush head to rotate, thus improving the friction effect during normal brushing action. Rotary toothbrush is noisy, and its teeth are clean, but it has great wear on teeth, so it is not recommended to use it for a long time.

The working principle of acoustic wave electric toothbrush: the acoustic wave vibrating toothbrush causes high-frequency vibration through the motor built in the machine body. The driven motion can make the brush head swing at high frequency in the direction perpendicular to the brush handle, but the swing amplitude is very small, generally about 5 mm up and down. The oral cavity is cleaned by constantly brushing up and down and generating water impact.
