Embodiment Construction

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] Such as figure 1 , image 3 , Figure 4 , Figure 5 As shown, the size of the entire ultrasonic atomizing nozzle is one ultrasonic pressure wave wavelength. The middle of the two piezoelectric ceramics 3 is the nodal surface 1, the distance between the nodal surface 1 and the left end surface of the ultrasonic atomizing nozzle is 1 / 4 wavelength, and the nodal surface 1 is 1 / 4 wavelength from the right end surface of the front cover. The midpoint of the flange 14 is the nodal surface 2, the distance between the nodal surface 2 and the right end surface of the front cover is 1 / 4 wavelength, and the nodal surface 2 is 1 / 4 wavelength from the right end surface of the ultrasonic atomizing nozzle. The left ends of the two piezoelectric ceramics 3 are respectively connected to a thin electrode 2 . The thin electrode 2 at the left...

Abstract

The invention discloses a vine-leaf line type low-frequency ultrasonic three-time atomization nozzle, and the overall vibration direction of the nozzle is the axial direction. The horn of the creeper-leaf linear low-frequency ultrasonic three-time atomization nozzle of the present invention is a creeper-leaf linear composite horn. The metal used in the vine-leaf linear composite horn is small in size and generates less heat, which overcomes the shortcomings of the conical horn and the stepped horn with large metal volume and high heat generation; the vine-leaf linear low-frequency ultrasonic The three-time atomization nozzle, through the wind force of the fan at the air inlet pipe, makes the droplets atomize for the third time on the right end surface of the metal sheet, which breaks through the shortcoming of low-frequency ultrasonic atomization that is difficult to generate ultra-fine droplets, and can be used for fog Chemical cultivation and ultrasonic spraying and other fields.

Description

technical field [0001] The invention belongs to the field of atomization cultivation, and in particular relates to an ultrasonic atomization nozzle technology. Background technique [0002] Ultrasonic nebulizer has a wide application prospect in the field of agricultural engineering due to its advantages of fine and uniform droplet size. Ultrasonic atomization refers to the use of high-frequency electronic oscillation, through the high-frequency resonance of the ceramic atomization sheet, to break up the molecular structure of liquid water to produce natural and elegant water mist, without heating or adding any chemical reagents. At present, the main shapes of the horn of the ultrasonic atomizing nozzle are conical, Bezier and stepped. The conical horn has a simple structure and is easy to design and manufacture, but its magnification factor is low; the stepped horn has a high magnification factor, but also has high stress concentration and is easy to break. Conical horns ...
