Atomizing device capable of increasing atomization quantity

Abstract

The invention provides an atomizing device capable of increasing atomization quantity; the atomizing device comprises a structure sheet, a nozzle sheet and a piezoelectric ring; the punching technology is employed to form a through hole in the center of the structure sheet, and the surrounding of the through hole is provided with at least one stress gathering zone like a protrusion or deformation portion; the nozzle sheet is clamped between the structure sheet and the piezoelectric ring, and provided with a plurality of nozzles corresponding to the through hole; when the piezoelectric ring is driven to enable the structure sheet and the nozzle sheet to synchronically vibrate, a to-be-atomized liquid can be atomized and sprayed out from the plurality of nozzles close to the stress gathering zone, thus greatly improving instant atomization quantity, and further reducing application energy loss.

Description

technical field [0001] The present invention relates to the field of liquid atomization equipment, in particular to an atomization device that uses stamping technology to make a plurality of stress concentration points on a metal structure sheet, so that the amount of atomization can be greatly increased, and the energy consumption during use can be effectively reduced consumer. Background technique [0002] According to the current common liquid atomization device on the market, it uses a piezoelectric (PZT) ring made of piezoelectric materials such as lead zirconate titanate. When the voltage is input, the body and the attached metal back The plate produces a telescopic deformation phenomenon, which uses the vibration energy transmitted in the form of waves to make a nozzle hole sheet located on one side of the piezoelectric material, and the liquid near the nozzle hole is atomized into fine molecules and then sprayed out.

Problems solved by technology

Yet this traditional orifice sheet will cause following shortcoming because of being limited by its plane shape: 1, when vibration energy is transmitted, its transmission direction is transferred toward the center by the outer periphery of this orifice sheet, so vibration energy The generated stress will be excessively concentrated in the center, which will cause the nozzle hole to break and shorten the service life; 2. Since the vibration energy is concentrated in the center, the atomization area is only formed near the center of the nozzle hole, so it can There are not many effective nozzle holes, and the amount of atomization is naturally not good; 3. Moreover, because the spray area is excessively concentrated in the central area, the density of the atomized liquid molecules is excessively concentrated, and it is easy to make the droplets collide in the center area. Together and combined into large-sized droplets, resulting in a decrease in atomization efficiency

However, in order to achieve the best atomization performance, the orifice sheet of this kind must have sufficient depth in order to achieve the best atomization performance, and the radius of curvature will usually be increased to reduce the effective atomization range; To increase the effective atomization range, it is necessary to increase the processing radius of curvature, resulting in shallower processing depth and poorer atomization efficiency.

Furthermore, since the orifice plate is made of metal material, the material itself will be stretched after processing, but the longer the diameter of the hemispherical structure, the lower the structural tension, resulting in weakened input force and a weaker overall structure. also weakened

Furthermore, due to the design of the hemispherical surface structure of the prior art orifice sheet, most of the vibration wave energy will still be concentrated in the central area after being transmitted, so that only the micropores located in the central part can effectively move, while the peripheral area The micropores cannot be used effectively due to insufficient vibration energy, resulting in that the atomization area cannot reach the original design area, and it will also affect the amount of atomization during use.

However, such as U.S. Patent No. 6651650, the plurality of nozzle holes on the nozzle hole plate are arranged in a hexagonal shape, which is expected to increase the atomization efficiency, but the actual effect is different from the atomization efficiency of the general circular arrangement. Not much, completely unable to increase the amount of atomization during use

[0005] Most of the designs of the above-mentioned orifice plates are aimed at improving the atomization efficiency, and the effect is limited, and there is no mention of energy consumption. In view of this, the inventor proposed an atomization device that can increase the amount of atomization , not only can increase the instant atomization amount, but also further reduce the energy consumption during use
