Abstract: A micro-droplet generator comprises a main body, having a chamber accommodating liquid to be sprayed and a lateral opening, a spraying plate, placed in the opening and having a plurality of spraying holes as well as an inner side, a vibrating element, glued on the spraying plate and driving vibrations thereof, and a projection, placed inside the chamber and having an outer side touch with the inner side of the spraying plate, wherein a narrow space is left between the inner side of the spraying plate and the outer side of the projection, which upon the vibrations of the spraying plate has a varying width, upon becoming wider sucking in liquid from the chamber, and upon becoming narrower pressing out liquid through the spraying holes.

Abstract: The present invention provides a liquid atomizer for atomizing liquid and applied in an atomizing device having an accommodating space and a through hole. The liquid atomizer includes a vibrating element having a first hole corresponding to the through hole; a spray plate having a plurality of spraying holes corresponding to the first hole and being connected with the vibrating element; and a structure element having a second hole corresponding to the plurality of spraying holes of the spray plate and being connected with the spray plate so that the spray plate is disposed between the vibrating element and the structure element. The vibrating element, the spray plate and the structure element are assembled in the accommodating space of the atomizing device. Liquids are atomized via the spraying holes of the spray plate.

Abstract: A mist generating apparatus comprises a case, having a chamber, an inlet and an opening, an auxiliary vibrating element, mounted in said opening of said case and having a central hole and a periphery, a vibrating element, connected with said vibrating element at said periphery thereof and having an electrode and a connecting wire, and a spraying plate, having a plurality of spraying holes, set on said central hole of said auxiliary vibrating element, wherein said vibrating element generates vibrations which are transmitted to said auxiliary vibrating element, being enhanced by a projecting part thereof, then further transmitted to said spraying plate, so that liquid in said chamber is pressed through said spraying holes and mist is generated, while manufacturing cost is reduced, spraying effectivity is enhanced, noise is reduced, and lifetime is enhanced.

Abstract: A spraying device comprises a spraying plate, having a plurality of tiny holes, a vibrating element, set on a periphery of the spraying plate, and driving a vibrating movement thereof, a wrapping layer, made of soft material and tightly surrounding the vibrating element, sealing the vibrating element from the liquid, and a fastening cap, allowing for quick mounting and dismounting of the spraying device; wherein the vibrating movement of the spraying plate causes liquid adjacent to a lower side of the spraying plate to be periodically compressed and thereby to be pressed through the holes of the spraying plate, and wherein the wrapping layer prevents external interference with the vibrating movement, at the same time minimizing transmission losses of vibrational energy, enhancing effectivity of spraying.

Abstract: A micro-droplet generator comprises a main body, having a chamber accommodating liquid to be sprayed and a lateral opening, a spraying plate, placed in the opening and having a plurality of spraying holes as well as an inner side, a vibrating element, glued on the spraying plate and driving vibrations thereof, and a top surface carrier, placed inside the chamber and having a top surface that with the inner side of the spraying plate forms an inner part of the chamber, wherein a narrow space is left between the inner side of the spraying plate and the top surface of the projection, which upon the vibrations of the spraying plate has a varying width, upon becoming wider sucking in liquid from the chamber, and upon becoming narrower pressing out liquid through the spraying holes.
