An atomizer nozzle comprises an outer cover, a medicine-filling container, and a washer, an atomizing module, a fixed member and an inner cover installed between the outer cover and the medicine-filling container, such that the piezoelectric material and the micro meshes of the atomizing module are completely separated from each other by the fixed member and the washer, so as to prevent the atomized medical liquid molecules from being contaminated by heavy metal of the piezoelectric material. The disclosed atomizer nozzle is characterized by less components and simplified structure, capable of reducing the manufacturing cost, easily performing the cleaning and disinfection processes, and increasing the structural strength and ability of withstanding the destruction of an external force. Besides, with the simplified structure of the disclosed atomizer nozzle, it is capable of further micronizing the sprayed aerial fog, so as to effectively screen the qualified particles of aerial fog for being provided to the patient, thereby precisely controlling the medication dosage from doctors advice.一種霧化器噴頭,係在一外蓋與一盛藥容器之間安裝一墊片、一霧化模組、一固定元件與一內蓋,使得霧化模組之壓電材料與微網孔被固定元件與墊片完全隔開,避免從微網孔噴出的霧化藥液分子受到壓電材料的重金屬污染;本發明同時將元件少量化、結構簡單化,使得製造成本更低,清潔消毒更容易,同時使結構強度提升,抗外力破壞能力更高;另一方面,藉由精簡的結構,可以使噴出的氣霧進一步更微細化,以有效篩選出合格的氣霧顆粒輸出給病患,進而精確控制醫囑之用藥量。1‧‧‧盛藥容器10‧‧‧盛藥空間12‧‧‧固定爪121‧‧‧扣合孔13‧‧‧環形凹溝312‧‧‧微網孔4‧‧‧固定元件5‧‧‧內蓋6‧‧‧外蓋61‧‧‧筒體62‧‧‧噴出口63‧‧‧內凸緣64‧‧‧篩選器641‧‧‧撞擊部65‧‧‧扣合部L‧‧‧藥液
