Claims (6)
基端側に設けた圧電素子の微小変位を増幅し、先端側へ伝達する共振器を有し、縦振動モードの超音波振動を発生する超音波振動子と、
前記超音波振動子の先端側端面又はこの端面に設置した振動板に対して液体を供給する液体供給手段と、
前記液体供給手段から供給される液体の供給圧力を損失させる圧力損失部材と、
を具備したことを特徴とする噴霧ヘッド。In a spray head that atomizes and sprays liquid by ultrasonic vibration,
An ultrasonic transducer that has a resonator that amplifies a minute displacement of a piezoelectric element provided on the base end side and transmits the amplified displacement to the tip end side, and generates ultrasonic vibration in a longitudinal vibration mode;
A liquid supply means for supplying a liquid to the end face of the ultrasonic transducer or the diaphragm installed on the end face;
A pressure loss member for losing the supply pressure of the liquid supplied from the liquid supply means;
A spray head characterized by comprising:
前記噴霧ヘッドは、前記超音波振動子の端面径方向に所定隙間を有して設置される円筒管を備え、 The spray head includes a cylindrical tube installed with a predetermined gap in the radial direction of the end face of the ultrasonic transducer,
前記円筒管は、前記超音波振動子の外周を覆うように前記共振器の基端側に設けられ、前記超音波振動子が縦振動モードで超音波振動するのに伴い、前記液体供給手段から供給される液体が前記共振器の先端側端面又はこの端面に設置した振動板に対して自給されるよう前記共振器の先端側端面径方向に所定隙間を形成して設置されることを特徴とする請求項１に記載の噴霧ヘッド。 The cylindrical tube is provided on the proximal end side of the resonator so as to cover the outer periphery of the ultrasonic vibrator, and the ultrasonic vibrator vibrates ultrasonically in a longitudinal vibration mode from the liquid supply unit. The liquid to be supplied is installed with a predetermined gap in the radial direction of the end surface on the tip side of the resonator so that the supplied liquid is self-supplied to the end surface on the tip side of the resonator or the diaphragm installed on the end surface. The spray head according to claim 1.
前記噴霧ヘッドは、前記超音波振動子の端面径方向に所定隙間を有して設置される円筒管と、 The spray head is a cylindrical tube installed with a predetermined gap in the end face radial direction of the ultrasonic transducer;
前記円筒管の先端側端面に設置されたメッシュプレートと、 A mesh plate installed on the end surface of the cylindrical tube;
を備えることを特徴とする請求項１に記載の噴霧ヘッド。The spray head according to claim 1, comprising:
