Description

Electric toothbrush device

Technical Field

The invention relates to the field of oral cleaning, in particular to an electric toothbrush device.

Background

The technology of electric toothbrushes has grown mature and consumers have more time for the function of electric toothbrushes. As the functional effects of cosmetic products, such as radio frequency technology and EMS technology, are verified and matured, there have been many attempts to add related technologies to cleaning products, such as electric toothbrushes. Many toothpastes contain chargeable organic and inorganic molecular compounds, and when activated by radio frequency current, the toothpaste molecules act as electrolyte molecules in the medium and flow along the tooth surface. When brushing teeth, the charged particles can break the strong molecular bonds which can make impurities such as stains and tartar adhered on the surface of teeth, and clean away stubborn impurities.

The brush head of the radio frequency toothbrush is provided with the electrodes, the electrodes are arranged in the bristles, the brush head needs to be integrally replaced after being used for a certain time, the replacement cost of the brush head with the electrodes and the bristles is high, and the use cost of consumers is increased. In addition, when a plurality of electrodes are arranged in the bristles, an insulation barrier is required to be arranged to ensure that the electrodes do not interfere with each other and work normally, the height of the insulation barrier is higher than that of the electrodes, and discomfort can be brought to a user when the user brushes the teeth.

There is therefore a need to solve the above problems.
