Cov kev tshawb fawb cuam tshuam ntseeg tias ultrasonic atomization yog cov txheej txheem ntawm kev siv lub zog ultrasonic los ua cov kua dej zoo hauv cov roj theem, uas yog, ultrasonic tsis yog tsim los ntawm cov kua vibrating, thiab cov vibration peaks tsim los ntawm lub amplitude cais thiab tawg. cov dej los ntawm qhov chaw. Raws li lub ultrasonic zaus nce, cov atomized kua droplets ua finer thiab finer. Feem ntau, nyob rau hauv qhov kev txiav txim ntawm ultrasonic vibration zaus, cov kua dej zoo tuaj yeem tau txais. Tsis tas li ntawd, lub teb zaus ultrasonic kuj tseem tuaj yeem tshem tawm lossis nyias cov txheej txheem ciam teb nyob ze ntawm qhov chaw hloov hluav taws xob, yog li txhawb kev hloov hluav taws xob.
Ultrasonic nebulizers muab faib ua ob pawg: hydrodynamic thiab electroacoustic transducers. Hydrodynamic ultrasonic atomization siv high-speed gas los yog kua kom excite lub resonant kab noj hniav los tsim ultrasound. Qhov ntau zaus yog txiav txim siab los ntawm geometric qhov loj ntawm lub resonant kab noj hniav, thiab qhov loj me me yog cuam tshuam nrog cov kua dej ntws, cua siab thiab cov qauv nozzle. Ultrasonic atomization tshuab siv hydrodynamic ultrasonic atomizer, thiab ultrasonic atomization ntawm cov kua xov xwm xws li dej, organic kua, thiab molten hlau kuj feem ntau siv rau hauv daim ntawv no.
Lub tshuab hluav taws xob-acoustic transducer hom ultrasonic atomization siv lub transducer los hloov high-frequency electromagnetic oscillations mus rau mechanical oscillations ntawm cov kua, rhuav cov kua rau hauv pos huab. Muaj ob hom ntawv tseem ceeb: ib qho yog tias lub piezoelectric transducer radiates muaj zog ultrasound hauv cov kua, radiates rau hauv cov kua los ntawm ib tug nyias lub suab-permeable membrane, thiab tsim cov ciav-zoo li atomization ntawm cov kua nto, uas yog lub hauv paus ntsiab lus ntawm ib tug raug ultrasonic. humidifier; Lwm qhov yog tias cov kua ntws mus rau saum npoo ntawm ultrasonic concentrator thiab tsim cov kua nyias txheej. Cov txheej nyias nyias excites nto nro nthwv dej nyob rau hauv qhov kev txiav txim ntawm ultrasonic kev co. Thaum lub amplitude ntawm lub vibration nto mus txog ib tug tej yam nqi, cov kua tee ya los ntawm lub yoj crest. tawm mus tsim atomization.
Lub atomizing nozzle yog ib qho khoom siv hauv cov khoom siv atomizing uas ua rau lub atomizing nruab nrab kom tau txais lub zog siab thiab kev kub ceev, thiab tseem yog ib feem tseem ceeb uas ua lub luag haujlwm tseem ceeb hauv atomization efficiency thiab kev ruaj ntseg ntawm cov txheej txheem atomization. Nws txoj haujlwm yog los tswj cov dej ntws thiab cov qauv ntawm cov atomized nruab nrab kom ua tau zoo ua kua hlau thiab tsim cov hmoov nrog cov khoom tshwj xeeb. Lub atomizing nozzle yog qhov tseeb transducer, uas hloov lub zog kinetic ntawm cov pa roj siab rau hauv lub zog saum npoo ntawm cov hlau. Raws li ib tug transducer, nws lub zog conversion efficiency yog qhov tseem ceeb.
