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.
