Cov txhuam hniav hluav taws xob ua haujlwm li cas

Cov txhuam hniav hluav taws xob feem ntau poob rau hauv ob pawg raws li lawv txoj haujlwm ua haujlwm: sonic electric txhuam txhuam thiab txhuam txhuam hluav taws xob.

Sonic Electric Toothbrush:

Feem ntau ua haujlwm siv lub tshuab me me DC lub cev muaj zog, uas tsav lub taub hau txhuam kom oscillate sai ntawm sab mus rau sab, tsim cov tshuab kev vibrations, piv txwv li, suab tsis.

Lub suab nthwv dej zaus tsim los ntawm sonic electric txhuam hniav thaum lub sijhawm ua haujlwm yog feem ntau siab dua 260 zaug ib ob. Qhov siab - zaus vibration no ua rau cov tshuaj txhuam hniav ua kom zoo, nkag mus tob rau hauv qhov sib txawv ntawm cov hniav kom cais cov plaque thiab cov khoom khib nyiab los ntawm cov hniav thiab cov crevices, yog li ua tiav cov nyhuv tu zoo dua.

Rotary Electric Toothbrush:

Siv lub tshuab sab hauv los tsav lub taub hau txhuam txhuam kom tig, ua kom muaj kev sib txhuam ntawm cov hniav thiab yog li tshem tawm cov quav hniav thiab cov khoom noj khoom haus zoo dua.

Rotary electric txhuam txhuam taub hau feem ntau muaj ntau hom kev sib txawv, xws li kev sib hloov unidirectional, kev sib hloov bidirectional, thiab ntau- lub kaum sab xis.
