An atomizer mouthpiece comprises a main body integrally formed and a connection tube interconnected at one side of the main body. The main body has a surrounding wall for defining an inner hole. The surrounding wall has a middle section corresponding to the connection tube, an outlet part connected to one end of the middle section, and a gas storage part connected to the other end of the middle section. The middle section surrounds to form an introduction inner diameter not less than 30 mm, and the introduction inner diameter is corresponded to the connection tube. A rear section distance from the central line of the connection tube to the terminal of the gas storage part is not greater than three times the introduction inner diameter. Thus, the introduction inner diameter corresponding to the connection tube can smoothly introduce atomized medicine, and the gas storage section may avoid interference generation.一種霧化含口器,包含一以一體成型方式製成的主體及一相交連結於該主體一側的接管,該主體具有一可界定出一內孔的環壁,該環壁具有一對應該接管的中段、一連結於該中段一端的出氣部及一連結於該中段另一端的儲氣部,該中段圍繞形成有一不小於30 mm的導入內徑,該導入內徑對應於該接管,該接管的一中心線至該儲氣部末端之間的一後段距離不大於該導入內徑的3倍。藉此,對應該接管的導入內徑可順利導入霧狀藥劑,且該儲氣段避免產生干涉。100‧‧‧霧化含口器10‧‧‧主體11‧‧‧環壁12‧‧‧內孔13‧‧‧中段14‧‧‧出氣部15‧‧‧儲氣部16‧‧‧導引段161‧‧‧圓弧部162‧‧‧圓錐部d1‧‧‧導入內徑d2‧‧‧前口徑d3‧‧‧後口徑20‧‧‧接管L‧‧‧中心線D‧‧‧後段距離200‧‧‧噴霧瓶300‧‧‧輸氣管
