CN2374060Y - Two-side toothbrush - Google Patents

Abstract

The utility model relates to a two-side toothbrush. A movable pressing plate 10 and a static pressing plate 13 lead a toothed rack to move on a smooth track way in parallel, so two brush heads 3 are driven by an elastic brush handle 4 to rotate towards the inner side. When two brush bristles 1 are subjected to the resistance force of gum (or teeth), the angle of a gear shaft root is driven to change by the elastic brush handle 4, and the length along the direction of a perpendicular face of an elastic basal seat 2 is changed. Excessive elasticity is absorbed by the two components. Under the condition that the friction force requirement between the gum (or the teeth) and the brush bristles is satisfied, combined part dirt at a connecting curve line position between the gum and the teeth can be cleaned by the brush bristles, and the dirt of two faces of the teeth can be cleaned one time. The brush bristles are led to move along the direction of tooth gap by a natural and correct method, and the acting force of the elastic restoring force of the two pressing plates is loosened, so the brush bristles can restore to the original position.
