A kind of liquid atomization circuit, the atomization mould group of coupling one liquid of what atomization, liquid atomization circuit includes a converting unit, a control unit and a voltage-adjusting unit. Control unit couples converting unit, and control unit is to control one conversion voltage of converting unit output. Voltage-adjusting unit couples between what converting unit and atomization mould group. Wherein, voltage-adjusting unit exports a driving voltage according to conversion voltage and gives atomization mould group, and driving voltage includes a plurality of electrolysis sections and a plurality of negative level sections, each electrolysis section, which is meant, shows that atomization mould group carries out a positive cell reaction, and each negative level section, which is meant, shows that atomization mould group carries out a reverse electrolysis reaction.一種液體霧化電路，耦接於一液體霧化的霧化模組，液體霧化電路包括一轉換單元、一控制單元及一電壓調整單元。控制單元耦接轉換單元，控制單元用以控制轉換單元輸出一轉換電壓。電壓調整單元耦接於轉換單元與霧化模組之間。其中，電壓調整單元根據轉換電壓以輸出一驅動電壓給霧化模組，而驅動電壓包括複數個電解區段及複數個負準位區段，各電解區段係指示霧化模組進行一正向電解反應，各負準位區段係指示霧化模組進行一逆向電解反應。
