A nozzle plate module for using in a nebulizer is disclosed and comprises a piezoelectric plate, a carrying plate and a nozzle plate, the piezoelectric plate has a first hollow opening, the carrying plate has a protruding structure and a second hollow opening, wherein the piezoelectric plate pastes on a first surface of the carrying plate, the protruding structure faces the piezoelectric plate and penetrates the first hollow opening of the piezoelectric plate, and the nozzle plate disposes on the second surface of the carrying plates and covers on the second 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;壓電片具有一第一鏤空圓孔,承載片具有凸出結構及第二鏤空圓孔;其中,壓電片設置貼合於承載片之一第一表面上,且承載片之凸出結構係相對於壓電片而設置,並凸露於壓電片之第一鏤空圓孔中,噴孔片則對應設置於承載片之第二表面上,並覆蓋於承載片之第二鏤空圓孔上,當壓電片壓電致動時,透過凸出結構降低承載片剛性,輔助承載片之能量傳遞至噴孔片上提升霧化振幅。3‧‧‧噴孔片模組30‧‧‧壓電片301‧‧‧第一鏤空圓孔313‧‧‧第二鏤空圓孔31‧‧‧承載片310‧‧‧第一表面311‧‧‧第二表面312‧‧‧凸出結構32‧‧‧噴孔片
