Technical field
The present invention relates to a kind of atomizing piece, more particularly to a kind of corrosion-resistant Sandwich type piezoelectric ceramics ultrasound atomizer plate.
Background technology
In the prior art, piezoelectric ceramic ultrasound atomizing piece is that metallic membrane is attached into piezoelectric ceramics surface, and in gold
Belong to punching in the center certain limit of diaphragm and be used as liquid passage path, metallic membrane is both the carrier of piezoelectric ceramics, is liquid again
The path that body passes through.Metallic membrane axial vibration pattern is driven by the radial vibration mode of piezoelectric ceramic piece, and then makes liquid
Atomization.The metallic membrane of such a structure and its liquid latus rectum region are integral making；On the one hand, because metallic membrane is piezoelectricity pottery
The carrier of porcelain, so it must is fulfilled for certain intensity, monolithic construction atomizing effect is poor, and limits metallic membrane liquid and lead to
Footpath region can not make very big concave surface, not only influence nebulization efficiency, and the difficulty of processing of monoblock type metallic membrane is high；It is another
Aspect, such a structure type energy conversion efficiency is low, and atomizing effect is undesirable.In addition, metallic membrane it is more using stainless steel as
Material；Because material is hard, the defects of energy conversion efficiency is low, and atomizing effect is poor, and the particle being atomized out is big be present.
Core component of the ceramic atomizing piece as ultrasonic ultrasonic delay line memory, need to connect with liquid for a long time in use
Touch, in the presence of ultrasonic wave, cavitation corrosion be present；In the presence of alternating current, electrolytic etching be present；If contain in liquid
, chemical attack also be present in other chemical substances such as disinfectant, acetic acid.Three kinds of corrosion collective effects, extremely easily by electrode breakages
Fall.Therefore, it is necessary to improvement is made to existing atomizing piece.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide one kind can in acid, alkaline environment long-term work
The corrosion-resistant piezoelectric ceramics ultrasound atomizer plate made, improves its service life.
What the present invention was achieved through the following technical solutions, a kind of corrosion-resistant Sandwich type piezoelectric ceramics ultrasound atomizer plate, including
The metallic membrane of two piezoelectric ceramic pieces and fixed clamp between two piezoelectric ceramic pieces, two piezoelectric ceramic piece surfaces
One layer of anticorrosive coat of upper covering；The metallic membrane center offers latus rectum of the through hole as liquid, the through hole and the piezoelectricity
The centre bore of ceramic ring plate is corresponding, and the atomizing piece also includes a waveform sieve for being furnished with orifice, the welding of waveform sieve
It is fixed on the via regions of metallic membrane.
Further, the welding medium between the waveform sieve and metallic membrane is copper medium.
Further, the anticorrosive coat is nano zircite protective layer.
Further, the waveform sieve is highly equal to the thickness of metallic membrane.
Further, the waveform sieve is made by the metal material of soft texture.
Further, the metal material of the soft texture is platinum.
Further, the orifice is bellmouth, and the lower aperture of the orifice is more than upper aperture.
Further, the thickness of the nano zircite protective layer is 5 ~ 30 μm.
The beneficial effect that the present invention is reached：1. it is divided into two lists using metallic membrane body and as the sieve of liquid latus rectum
Only part, while metal membrane ruggedness is ensured, waveform sieve with improving atomizing effect and nebulization efficiency；
2. sieve is welded and fixed with metallic membrane by medium of copper, using the good ductility of copper, overcome split type
The drawbacks of structural energy conversion is low, ensure that atomizing effect；
3. waveform sieve sieve uses the metal material of soft texture, it is easy to the making of sieve, page ensure that atomizing effect, make
Obtain liquid to be easier to be broken up atomization, the liquid particles being atomized out are smaller, and residual is few；
4. being sprayed on piezoelectric ceramic piece surface using nano zircite forms protective layer, this layer of protective layer causes piezoelectric ceramic piece can
To be worked for a long time without being corroded in disinfectant, acidity, alkaline environment, the service life of ultrasonic atomizatio piece is substantially increased.
