It can atomize various solutions with different pH values.
Description
Technical field
The present invention relates to a kind of transducer, especially for the ultrasonic atomization transducer of air sterillization, humidification or artificial spraying.
Background technology
The traditional transducer that is used for the supersonic atomizer of air wetting, sterilization or artificial spraying because its assembly is an acid and alkali-resistance not, generally only uses in pure water.Chinese patent ZL02215575.9 " the floating transducer of supersonic atomizer " utility model, a kind of transducer of supersonic atomizer that makes is disclosed from the technical scheme that floats over best level atomizing work, all change the main components of transducer into buoyancy working of plastics preferably, the acid and alkali-resistance ability of transducer is improved.But it is the same with the transducer of traditional in the past supersonic atomizer, the metallic conduction coating of its core component piezoelectric ceramic wafer (being commonly called as the oscillator sheet) is acid and alkali-resistance not still, usually also require in the liquid of pH value, to use for neutrality, in case be used for the relatively poor area of water quality or be directly used in the atomizing of acid-base solution, several weeks of the many persons of conductive coating that oscillator sheet surface contacts with liquid are a few days damage that will be corroded at least, must change, not only influence the reliability of complete machine, and the use cost height, also bother very much.Therefore, make the extent of spreading amd application of ultrasonic atomization utensil and field be subjected to serious restriction.
Summary of the invention
The object of the invention provides a kind of transducer of ultrasonic atomizing device that can make from floating over best level atomizing work, again can be at the different quality of various places, the floating acid and alkali-resistance transducer of the normal supersonic atomizer that uses in the liquid of various pH values or the soup.
The objective of the invention is to realize by following proposal: floating acid and alkali-resistance transducer is by comprising buoyancy aid, housing, gland and be arranged in oscillator sheet in the gland, sealing ring, conductive electrode, contact conductor and plug are formed, it is characterized in that: by sealing ring, the lower plane of oscillator sheet, the inner groovy of gland constitutes the air chamber of sealing, and sealing ring, the last plane of oscillator sheet, with the liquid-accumulating chamber that places the sealing of sound passing membrane composition on the sealing ring, completely fill neutral entrant sound solution in the liquid-accumulating chamber, transducer is when floating on the work of atomized liquid intrinsic fog, oscillator sheet and the liquid that needs atomizing, sound transparent layer by neutral entrant sound liquid and sound passing membrane composition is isolated, the conductive coating on oscillator sheet surface only contacts with neutral entrant sound solution in the liquid-accumulating chamber, simultaneously, other component parts of transducer all adopt the material manufacturing of acid and alkali-resistance, have got rid of the corrosion of atomized liquid acid-base value to transducer fully.Thereby, the solution of various water quality or any pH value, as long as the limit that its viscosity, density, surface tension allow less than the ultrasonic atomizatio cavitation threshold, all will normally be atomized, and the working life of transducer and oscillator sheet no longer is subjected to the influence of atomized liquid character, and a big hidden danger of ultrasonic atomizatio utensil reliability is solved.
Description of drawings
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail:
Accompanying drawing is the full section schematic diagram of the floating acid and alkali-resistance transducer of supersonic atomizer of the present invention.
It is as follows to illustrate each label declaration: 1-transducer buoyancy aid; The 2-transducer housing; 3-shell wall side inlet opening; 4-taper atomized spray hole; 5-matrix entrant sound film; The neutral entrant sound liquid of 6-liquid-accumulating chamber; The special rubber seal of 7-; 8-oscillator sheet (piezoelectric ceramic wafer); 9-annular conductive electrode; 10-elastic conduction electrode; 11-connects the high frequency oscillation generator plug; The 12-contact conductor; 13-sealed air chamber; 14-transducer gland; 15-stainless steel trip bolt.
The specific embodiment
Make buoyancy aid 1 with foamed plastics, be pressed into transducer housing 2 with injection mould, gland 14, make matrix sound passing membrane 5 with hot pressing, rubber seal 7, conductive electrode 9 and elastic conduction electrode 10 are set in the groove of gland 14, connect contact conductor 12, and with the glue of acid and alkali-resistance or other materials fairlead is sealed fully and to block, to guarantee that the sealed air chamber 13 that the integral installation timing forms does not occur in gas leakage herein, in gland 14, establish conductive electrode 9 then, elastic electrode 10 top device oscillator sheets 8, again on oscillator sheet 8 device sealing ring 7, the groove that the last plane of oscillator sheet 8 and sealing ring 7 surround promptly with liquid-accumulating chamber 6.Neutral entrant sound liquid is added injection liquid-accumulating chamber 6, put matrix sound passing membrane 5, cover presses transducer housing 2, fastening stainless steel screw 15, the floating acid and alkali-resistance transducer that 1, one of suit upper float can be used in the ultrasonic atomizing device of various different qualities and any pH value atomized liquid is just made and is finished.
In order to make transducer nebulization efficiency of the present invention better, the neutral entrant sound liquid in the liquid-accumulating chamber 6 should select for use pH value to equal 7, the liquid medium that specific acoustic impedance is littler than pure water, for example castor-oil plant wet goods.The entrant sound film of forming sound transparent layer jointly with neutral entrant sound liquid should adopt then that mechanical strength is good, specific acoustic impedance as far as possible with pure water near and the material manufacturing of acid and alkali-resistance, for example polyethylene film etc.For preventing that sound wave from being absorbed by sound transparent layer, must not entrained air in the transducer liquid-accumulating chamber 6 during assembling, sound passing membrane 5 should be made matrix for this reason, external diameter is slightly larger than the external diameter of sealing ring 7, and thickness is advisable at 0.5～0.8mm.
Acid and alkali-resistance transducer of the present invention is made up of a plurality of components and parts, and all component parts that might touch atomized liquid all must acid and alkali-resistance.For this reason, the housing 2 of this transducer, buoyancy aid 1, gland 14, contact conductor 12 outsourcing cortexes are all made of plastic, and the silicon rubber of sealing ring 7 usefulness acid and alkali-resistances is special, and trip bolt 15 usefulness stainless steels are made.
Transducer architecture of the present invention is succinct, and dependable performance is used very convenient.Through the actual proof of using in multiple soups such as pure water, running water, river, lake water, well water, seawater, salt solution, alkaline solution, acid solution, peracetic acid disinfectant liquid, not only having solved traditional ultrasonic atomizatio utensil can not be in the normal use in the area of a water quality inferiority difficult problem, also started new way with the various pH value solution of ultrasonic atomizatio, thereby the ultrasonic atomizatio scope of application is extended to any area, and all trades and professions that atomization of liquid demand is arranged will be contained in the field that can apply.
