Composite atomization sheet and atomizer applying composite atomization sheet

Abstract

The invention relates to a composite atomization sheet. The composite atomization sheet comprises a matrix layer. An upper electrode layer is arranged on the upper surface of the matrix layer. A lower electrode layer is arranged on the lower surface of the matrix layer. The composite atomization sheet is characterized in that the surface side face of the center area of the upper electrode layer is coated with a polyimide film layer, and the part between the lower surface of the polyimide film layer and the surface side face of the upper electrode layer is further coated with a bonding layer. Due to the fact that the surface side face of the center area of the upper electrode layer is covered with the polyimide film layer, the upper electrode layer is protected.

Description

technical field [0001] The present invention relates to an atomizing sheet, which includes a substrate layer and metal electrode layers respectively attached to its upper and lower surfaces, and uses the substrate layer, such as a piezoelectric ceramic layer, during operation. The inherent ultrasonic vibration characteristics complete the atomization work. Specifically, the driving control circuit generates a driving voltage consistent with the resonant frequency of the matrix layer and applies it to the atomizing sheet, and the atomizing sheet will generate high-frequency resonance to break up the molecular structure of liquid water to produce a natural Elegant mist. Background technique [0002] The atomizing sheet is the core functional part of the atomizer. During the working process, the high-frequency vibration of the atomizing sheet generates ultrasonic waves to generate atomized gas. Ultrasonic waves are conducive to the generation of atomized gas, but at the same t...

Problems solved by technology

However, since the stainless steel diaphragm itself is also a metal film with metal conductive properties, the stainless steel diaphragm actually becomes a part of the electrode layer after being attached to the metal electrode layer, and the conductive stainless steel diaphragm will cause liquid charged and hurt people, for this reason, the conductivity of the stainless steel diaphragm will become a potential safety hazard that cannot be ignored

In addition, because the stainless steel diaphragm has a relatively large weight, it becomes the load of the substrate layer during the vibration process of the substrate layer and consumes the vibration energy of the substrate layer, which in turn affects the atomization. The atomization effect of the sheet

Moreover, because the stainless steel diaphragm has electrical conductivity, electric corrosion will also occur after long-term use, which will affect the anti-corrosion effect.

Secondly, because the surface of the stainless steel diaphragm is relatively rough, scale is easily adsorbed on it and is not easy to clean
