Description

Technical Field

[0001] The utility model relates to the technical field of root canal swishing devices, and more specifically, to a vibration damping structure of a root canal swishing device. Background Art

[0002] The root canal irrigator is driven by a high-frequency motor to generate high-frequency mechanical vibration, which is transmitted to the irrigating needle to activate the liquid medicine in the root canal, causing the liquid medicine to produce water flow and bubbles, thereby forming a flow effect in the root canal. This vibration will cause the liquid in the root canal to flow rapidly and hit the root canal wall, thereby loosening and cleaning the bacterial accumulation and pulp residue in the root canal. During use, the existing root canal irrigator uses the centrifugal force generated by the high-speed rotation of the eccentric transmission part driven by the motor to vibrate the turbulent irrigating needle connecting shaft. However, due to the lack of a vibration damping structure, a hard-to-hard contact is generated between the irrigating needle connecting shaft and the positioning pin and the irrigator shell to transmit the vibration wave, resulting in a large noise generated during the vibration operation of the irrigating needle connecting shaft, which affects the noise reduction and quietness performance of the root canal irrigator. In view of this, we propose a vibration damping structure for a root canal irrigator to solve the above problems. Utility Model Content
