In the prior art, the piezoelectric ceramic atomizing sheet is mainly applied to household humidification, office humidification, automobile humidification, fumigation atomization, medical cosmetology and the like, has wide application field, utilizes the principle of electronic high-frequency oscillation, disperses liquid water through high-frequency oscillation to generate water atomization to form very fine water drops, and sprays the water drops through a nozzle to form fog, wherein the water fog contains a large amount of air negative ions and moisture, and can increase air humidity and refresh air. Except atomizing water, can also atomizing essential oil etc. normally, when atomizing essential oil, all through dripping into appropriate amount of essential oil in aqueous, the atomizer comes out with water and essential oil atomizing jointly again, therefore essential oil need rely on water as the carrier, just can be atomized. If directly atomize essential oil or other solution that viscosity is higher, then need oil guide cotton or other porous materials, diffuse piezoelectric ceramic atomizing piece atomizing area after adsorbing solution and can atomize out, but the solution controllability that oil guide cotton or other porous materials adsorbed is poor, if the solution on piezoelectric ceramic atomizing piece atomizing surface is too much, then produce the phenomenon of splash or unable atomizing easily, if the solution on piezoelectric ceramic atomizing piece atomizing surface is too little, then the piezoelectric ceramic atomizing piece just produces the dry combustion phenomenon easily, then will cause serious influence to piezoelectric ceramic atomizing piece inner structure. Therefore, when a solution having a high viscosity is atomized, it is particularly important to control the amount of the solution on the atomization surface of the piezoelectric ceramic atomization sheet.
Therefore, it is a technical problem to be solved by those skilled in the art whether a piezoelectric ceramic atomizing sheet can be designed to overcome the above-mentioned drawbacks.
