Sonic toothbrush vibration structure for effectively reducing vibration of handle

Abstract

The invention provides a sonic toothbrush vibration structure for effectively reducing vibration of a handle. The sonic toothbrush vibration structure comprises the handle and a micro motor capable of generating vibration output, wherein a transmission rod which is formed by overall molding and transmits vibration to a toothbrush head body is arranged on the handle; the micro motor is fixed in an inner cavity of the upper part of the transmission rod; the transmission rod is in a flexible connection with the handle by a first damping rib long in axial direction and short in horizontal direction; a bracket is fixed in the handle; the lower part of the micro motor is connected with a support rod; the support rod is in the flexible connection with a second damping rib; the transmission rod and the support rod are driven by the micro motor to generate relative vibration with the handle; and high-frequency vibration generated by the transmission rod and the support rod is isolated with the handle by the first damping rib and the second damping rib. The sonic toothbrush vibration structure has the advantages of simple structure, reasonable design, convenience in carrying, stable and reliable working performance, relatively wide application scope, and the like and is an ideal tooth-cleaning and tooth-protecting appliance.

[0002] Toothbrush is the most commonly used tool for cleaning teeth. It is used to remove bacteria, tartar and small debris attached to the teeth. It can prevent periodontal diseases and protect people's oral hygiene and dental health. Toothbrushes on the market now Variety, different structures, such as Chinese patent, patent number: ZL200620102401.9 discloses a kind of sonic vibration toothbrush, including the brush head with bristles, the brush neck rod and the vibration part double as the brush handle, the vibration part is provided with vibration The joint is connected to the brush neck rod through the vibration joint, and other components such as the vibration source motor, the vibration rod and the main body electric board are all arranged in the handle that doubles as the vibration part. The main defect of this toothbrush is that the vibration source and the main body control board are arranged in the Together, it is easily damaged under high-frequency vibration, and the handle doubles as the vibration part to increase the vibration of the body, so the desired effect cannot be achieved
