1. Ua ntej ntawm tag nrho cov, koj yuav tsum paub seb hom nas repeller koj siv.Yog hais tias nws yog ib tug hu ua electromagnetic yoj los yog infrared repeller, nws yeej yuav tsis zoo.
2. Yog tias nws yog ib qhoultrasonic nas repeller, muaj ntau txoj hauv kev uas yuav cuam tshuam rau kev siv.Thawj qhov yog cuam tshuam nrog kev siv ib puag ncig, xws li kev teeb tsa ntawm cov khoom, chav sib cais, thiab lwm yam, lossis cov khoom siv (cov khoom thaiv) Yog tias qhov ntom ntom ntawm cov khoom hauv cheeb tsam tiv thaiv yog siab dhau, lossis cov khoom ntim ncaj qha rau hauv av. , los yog muaj ntau qhov chaw tuag, thiab lwm yam (uas yog, qhov chaw uas lub ultrasound tsis tuaj yeem ncav cuag los ntawm kev xav lossis kev cuam tshuam), qhov thib ob muaj peev xwm yog thiab qhov chaw ntawm tus nas repeller kuj muaj ntau yam ua rau nws.Yog txoj hauj lwm ntawm tus nasrepellertsis zoo muab tso rau, cov nyhuv ntawm tus nas repeller yuav tsis muaj zog thaum lub reflection nto tsim tsawg dua.Qhov thib peb muaj peev xwm yog hais tias lub hwj chim ntawm lub purchase ultrasonic nas repeller tsis txaus.Tom qab lub ultrasonic nthwv dej tau tshwm sim los yog refracted ob peb zaug, lub zog tau txo qis heev, thiab txawm tias attenuated mus rau lub ntsiab lus uas nws ua tsis tau raws li lub hom phiaj ntawm repelling nas.Yog li yog tias lub hwj chim ntawm tus nas repeller yuav yog Yog tias nws tsawg dhau, ultrasound yuav tsis tuaj yeem ua haujlwm.Cov neeg siv yuav tsum tau them sai sai rau cov ntsuas muaj feem xyuam thaum yuav cov khoom zoo sib xws.
3 Tsis tas li ntawd, yog tias qhov chaw tiv thaiv loj dhau thiab tus naj npawb ntawm cov nas rov siv tsis txaus, thiab cov yoj ultrasonic tsis tuaj yeem npog tag nrho cov kev tswj hwm, cov nyhuv yuav tsis zoo tagnrho.Hauv qhov no, koj yuav tsum xav txog qhov tsim nyog nce tus nasrepellers.Los yog qhov ceev ntawm kev tso kawm.
