Vibration isolator for oral irrigators

An oral irrigator comprising:

• a housing;
• a vibration generating component positioned within the housing;
• and
• an isolator assembly coupled to the vibration generating component comprising:
• a chassis coupled to the vibration generating component;
• an engagement arm coupled to the chassis;
• and
• a dampener positioned between the chassis and the housing, wherein the engagement arm engages a top surface of the dampener and a bottom surface of the dampener engages the housing.

An oral irrigator comprising:

• a substrate;
• a chassis;
• a vibration generating component supported by the chassis;
• and
• a dampener separating the chassis from the substrate to reduce transfer of vibrations from the vibration generating component to the substrate, the dampener including a body, and first and second slots defined on a side of the body;
• wherein
• a portion of the chassis is received in the first slot;
• and
• wherein the second slot is positioned between the first slot and the substrate to reduce transfer of vibrations to the substrate.
