Description

Technical Field

[0001] The utility model relates to the technical field of root canal irrigators, and more particularly to a irrigator which is easy to install and seal. Background Art

[0002] The root canal irrigator uses a high-frequency oscillation circuit to excite the ultrasonic transducer to generate high-frequency mechanical vibration, which is transmitted to the working tip to activate the liquid in the root canal, causing the liquid to generate 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, which helps to loosen and clean the bacterial accumulation and pulp residue in the root canal. During use, the existing root canal irrigators mostly use a structure in which the shell cover is snap-locked in the battery compartment. Although it is convenient to replace and install batteries, the poor sealing of this structure increases the risk of liquid impurities seeping into the battery compartment of the shell during alcohol wiping and water washing, affecting the overall installation and sealing effect of the root canal irrigator. In view of this, we propose an irrigator that is easy to install and seal to solve the above problems. Utility Model Content
