A nozzle plate module for using in a nebulizer is disclosed and comprises a piezoelectric plate, a carrying plate and a nozzle plate, the carrying plate has a protruding structure and a hollow opening, wherein the piezoelectric plate pastes on the carrying plate, and the nozzle plate covers on the hollow opening of the carrying plate, when the piezoelectric plate is drove, the protruding structure reduce the rigidness of the carrying plate and help the energy delivering from the carrying plate to the nozzle plate to promote the nebulization vibration.本案關於一種噴孔片模組,適用於霧化器,至少包括:壓電片、承載片及噴孔片;承載片具有一凸出結構及一鏤空圓孔;其中,該壓電片設置貼合於該承載片上,該噴孔片則對應覆蓋於該承載片之鏤空圓孔上,當該壓電片壓電致動時,透過該凸出結構降低該承載片剛性,輔助該承載片之能量傳遞至該噴孔片上提升霧化振幅。3‧‧‧噴孔片模組30‧‧‧壓電片301、313‧‧‧鏤空圓孔31‧‧‧承載片310‧‧‧第一表面311‧‧‧第二表面312‧‧‧凸出結構32‧‧‧噴孔片
