Disclosed is a dual air-chamber fully sealed piezoelectric nebulization module including a first casing, a second casing and a piezoelectric nebulization module, and the piezoelectric nebulization module is clamped between the casings by snapping and sealing to partition the internal space in the first casing and the second casing into two independent air chambers. In this design, a peripheral portion of the piezoelectric nebulization module is packaged to reduce the energy and vibration from being absorbed or inhibited during vibration and provides a space with good support and free vibration to enhance the nebulization efficiency. In addition, the design with the two independent air chambers can achieve the double-barrier sealing and isolating effect and reduce the chance of the piezoelectric nebulization module being corroded or damaged.一種雙氣室全罩密封壓電式霧化模組,其包括一第一殼體、一第二殼體及一壓電式霧化模組,並利用卡扣及膠合密封等方式將該壓電式霧化模組夾設於其間,使該第一殼體及該第二殼體的內部空間被分隔形成為二獨立氣室的設計。本創作之特色係藉由封裝於該壓電式霧化模組之周緣部位,可減低振動時能量及振波傳遞的效能被吸收或抑制,同時也可提供良好的支撐效果及自由振動之空間,據以提升其霧化效率;此外,該獨立雙氣室設計能夠發揮如同雙重屏障之密封隔離效果,大幅降低該壓電式霧化模組遭受侵蝕或破壞之可能性。4‧‧‧雙氣室全罩密封壓電式霧化模組41‧‧‧第一殼體411‧‧‧第一穿孔412‧‧‧第一環狀膠道413‧‧‧第一定位凸塊415‧‧‧第一檢測孔42‧‧‧第二殼體421‧‧‧第二穿孔422‧‧‧第二環狀膠道423‧‧‧第二定位凸塊425‧‧‧第二檢測孔43‧‧‧壓電式霧化模組431‧‧‧壓電致動器432‧‧‧霧化片4321‧‧‧噴孔433‧‧‧結構片44‧‧‧密封膠
