Txoj kev siv ultrasonic tu hniav hniav

Technical field

Lub invention muaj feem xyuam rau ib txoj kev teb ntawm kev tu cov av ntawm cov hniav cuav, tshwj xeeb tshaj yog rau cov txheej txheem keeb kwm yav dhau los ntawm kev ntxuav cov av ntawm cov hniav cuav los ntawm ultrasonic yoj.

Tom qab lub xyoo pua 21st, Tuam Tshoj tau nkag mus rau cov neeg laus, cov nroog loj xws li Shanghai,

In 2005, the elderly population aged 60 and above reached 2.5467 million, accounting for 18.89 percent of the city's registered population. With the arrival of aging, all kinds of problems arise, and China's attention to the aging society has always maintained a high level of concern. For example, most of the elderly have oral health problems, and with the improvement of China's national living standards, the elderly are paying more attention to their oral health, in the teeth loose or bad often take the initiative to assemble all kinds of dentures, in order to ensure the normal daily life and beautiful appearance.

Existing dentures, regardless of the use of various materials, often need to be cleaned after a period of time. At present, in economic considerations, the elderly often go to professional dental institutions for a cleaning after a long period of time. And cleaning the use of drugs or liquid medicine, complex operation, high cost. •

Txhawm rau kom ua tiav, yuav ua li cas los tsim ib txoj hauv kev uas tuaj yeem siv cov cuab yeej siv av uas twb muaj lawm thiab tshem tawm txhua yam av ntawm cov hniav hniav yog qhov teeb meem rau cov kws tshawb fawb hauv cov kev sib raug zoo. Cov ntsiab lus invention

Cov teeb meem kev daws teeb meem yog tias qhov kev tsim kho muab ib txoj hauv kev los ntxuav cov hniav cuav los ntawm ultrasonic yoj, aiming ntawm kev daws cov teeb meem saum toj no.

Txhawm rau daws cov teeb meem saum toj no, kev tsim khoom tiav los ntawm cov kauj ruam hauv qab no: thaum siv cov khoom tsim, cov hniav cuav raug tshem tawm ntawm lub qhov ncauj thiab muab tso rau hauv qing nrog lub tshuab hluav taws xob ultrasonic.

Nyob rau hauv lub thawv ntxhua khaub ncaws, tig rau lub tshuab hluav taws xob ultrasonic, xa tawm cov teeb liab vibration ntawm 20KHz zaus, thiab tom qab ntawd dhau lub ultrasonic yoj.

Lub ultrasonic transducer (poob taub hau) amplifies lub vibration teeb liab ntawm 20KHz zaus los ntawm hluav taws xob fais fab

Qhov cuam tshuam piezoelectric hloov pauv mus rau hauv cov khoom siv hluav taws xob ntau zaus, thiab cov neeg kho tshuab kev co ua rau kev co ntawm cov kua ntxuav.

Tsim ib txoj kab uas hla ntawm 50-500pm me npuas npuas, cov npuas no hauv ultrasonic longitudinal propagation tsim tsis zoo siab

Cov cheeb tsam yog tsim, loj hlob, thiab ceev ceev kaw ntawm qhov zoo siab, nyob rau hauv ib tug txheej txheem hu ua cavitation nyhuv, me me gases

Thaum lub npuas raug kaw, nws tuaj yeem ua rau lub sijhawm kub ntxhov ntawm ntau tshaj 1000 cua. Tsis tu ncua kev kub siab,

It's like a series of little explosions hitting the surface of the denture, removing all the debris that's left on the surface or between the cracks

Cov av flakes tawm sai sai, cia cov hniav ntxuav hniav dawb.

Piv nrog rau cov kos duab ua ntej, cov txiaj ntsig zoo ntawm kev tsim khoom yog tias kev ntxuav ultrasonic siv hauv kev tsim khoom yog sab hauv.

Cov qauv txheej sab nrauv yog qhov nyuaj dua, micro- qhov tsis sib xws, hlais, qhov, ces kaum, lub kaum sab xis tuag thiab lwm yam khoom ntawm cov khoom

Txhua tus muaj peev xwm ntxuav tau zoo, uas tsis sib haum los ntawm lwm txoj kev ntxuav, thiab yuav tsis ua rau cov hniav puas

Qhov saum npoo; Kev ua haujlwm ntawm txoj kev no yog qhov yooj yim thiab tuaj yeem ua tau raws li cov kev xav tau ntawm kev siv tsev neeg zoo tib yam.

Hom kev siv tshwj xeeb

Cov hauv qab no yog cov lus piav qhia ntxaws ntxiv ntawm kev tsim ua ke nrog rau hom kev siv tshwj xeeb:

Thaum siv cov invention, cov kauj ruam ua haujlwm yog raws li hauv qab no:

Ua ntej, cov hniav raug tshem tawm ntawm lub qhov ncauj thiab muab tso rau hauv lub thawv ntxuav nrog lub tshuab hluav taws xob ultrasonic.

Tig lub tshuab hluav taws xob ultrasonic, lub tshuab hluav taws xob ultrasonic xa tawm cov teeb liab ntau zaus oscillation; Tom qab ntawd, lub siab zaus vibration teeb liab yog amplified los ntawm ultrasonic transducer, thiab inverse piezoelectric nyhuv ntawm ultrasonic transducer (shock taub hau) yog hloov dua siab tshiab rau hauv siab zaus mechanical vibration.

Yuav ua rau kev vibration ntawm kev ntxuav cov dej txhua yam kev co, uas ua rau lub cheeb ntawm 50-500|jm qev

Npuas;

Cov npuas no tsim thiab loj hlob nyob rau hauv qhov tsis zoo siab cheeb tsam tsim los ntawm longitudinal kis tau tus mob ntawm ultrasonic yoj, thiab kaw sai heev nyob rau hauv lub zoo siab cheeb tsam, uas ua rau cov nyhuv cavitation. Cov npuas me tuaj yeem ua rau muaj kev kub ntxhov sai sai thaum kaw, cov npuas me me tas li cuam tshuam rau saum npoo ntawm cov hniav cuav, qhov chaw ntawm cov hniav cuav lossis qhov sib txawv ntawm cov av uas tseem tshuav sai sai, kom ua tiav lub hom phiaj ntawm kev ntxuav cov hniav cuav.

Hauv kev siv txoj kev tsim, ultrasonic yoj yog siv los ntxuav thiab tshem tawm cov av ntawm cov khoom uas muaj cov txheej txheem sab hauv thiab sab nraud, micro- qhov chaw tsis sib luag, slits, qhov, cov ces kaum thiab cov fab tuag, uas muaj cov yam ntxwv zoo, thiab kev ua haujlwm yog kev nyab xeeb thiab yooj yim. Nws tuaj yeem siv rau txhua yam ntawm cov hniav hniav ntawm cov ntaub ntawv tam sim no, thiab tuaj yeem siv hauv tsev neeg. Nws tsis yog qhov tsim nyog mus rau cov kws kho hniav cov tsev kho hniav rau kev tu hniav, uas yooj yim rau cov neeg laus.
