A mesh nebulizer includes a main body including a recess with a shape that is open upward. The main body includes a vibration portion with a vibration surface, and a liquid supply portion that supplies the liquid onto the vibration surface. The mesh nebulizer also includes a cap that openably and closeably covers the upper portion of the main body, and a replacement member that is separate from the main body and the cap and detachably mounted in the recess of the main body in advance when the nebulizer is to be used. The replacement member includes a film mesh portion, a bottom plate portion, and a side wall portion. When the cap is closed with respect to the main body, the protrusion portion of the cap presses the bottom plate portion of the replacement member toward the bottom surface of the recess, thus positioning the replacement member in the vertical axis direction of the main body.

A method of prepping a cylindrical inner surface of a bore using a high-frequency forced pulsed waterjet apparatus entails generating a pressurized waterjet using a high-pressure water pump, generating a high-frequency signal using a high-frequency signal generator, applying the high-frequency signal to a transducer having a microtip to cause the microtip to vibrate to thereby generate the high-frequency forced pulsed waterjet, and rotating the rotatable ultrasonic nozzle inside the bore to prep the inner cylindrical surface of the bore using the high-frequency forced pulsed waterjets exiting from the angled exit orifices of the rotatable ultrasonic nozzle.

A low frequency electrostatic ultrasonic atomising nozzle, relating to electrostatic atomisers in the field of agricultural engineering, and comprising a transducer rear cover plate (5), a piezoelectric ceramic (6), a transducer front cover plate (18), a nozzle variable amplitude rod (3), and a tightening screw (12), the tightening screw (12) passing in turn through circular central holes of the transducer rear cover plate (5), the piezoelectric ceramic (6), and the transducer front cover plate (18), the axial centre of the nozzle variable amplitude rod (3) being provided with a liquid intake channel (4), a gas intake channel (7) being provided at a position offset from the axial centre, and the top part of the nozzle variable amplitude rod (3) being machined into a concave spherical surface, the concave spherical surface being provided with a suspension ball (8). The suspension ball (8) is rotated at high speed using compressed air in an axially eccentric motion, and electrode electrification causes the suspension ball (8) to generate an electric field, such that the atomised drops produced by means of low frequency ultrasonic atomisation are further electrostatically atomised, and the electrostatically charged drops are sprayed from the nozzle. The present low frequency electrostatic ultrasonic atomising nozzle solves the problem of the difficulty for low frequency ultrasonic atomising nozzles to produce ultrafine atomised droplets, and electrostatically charges the atomised droplets, thereby increasing the adhesion of the atomised droplets and enabling same to more effectively adhere to a crop.
