Description

Electric toothbrush

Technical Field

The utility model relates to the technical field of toothbrush tools, in particular to an electric toothbrush.

Background

Compared with the common toothbrush, the electric toothbrush can more thoroughly remove dental plaque, reduce gingivitis, periodontal disease, gingival bleeding and other oral diseases. Specifically, the electric toothbrush can make the brush head generate high-frequency vibration through the rapid rotation or vibration of the motor core, so as to instantly decompose toothpaste into fine foam and deeply clean the tooth gaps; at the same time, the vibration of the brush hair can promote the blood circulation of the oral cavity and massage the gum tissue.

When the electric toothbrush head is used for brushing teeth deeply in the oral cavity, the side part and the back of the electric toothbrush head sometimes collide with teeth, and as the electric toothbrush head is made of hard materials and is directly connected with the vibrating shaft, the electric toothbrush head is in a high-frequency vibrating state, the back of the electric toothbrush head collides with the teeth to generate larger impact force on the teeth, and meanwhile, larger sound is generated, so that bad experience is generated. For loose or sensitive teeth, the gum or teeth are painful, so that the users are afraid of fear when brushing teeth with the electric acoustic toothbrush, even the users are abandoned, the teeth are not cleaned better continuously, and further loosening and anaphylactic symptoms caused by bacteria or residues are promoted, so that vicious circle is caused. Meanwhile, when the electric toothbrush head vibrates at high frequency, the scraping force of the electric toothbrush head and bristles on teeth is large, and the balance of cleanliness and use comfort cannot be realized. Thus, we propose a new electric toothbrush.
