An intake module includes an outer tube body defining an intake chamber (113) and having an intake end (111), and an inner tube body (12) disposed in the outer tube body and having an intake hole (121) communicating with the intake chamber (113). An intake lid (2) covers the intake end (111) and has an inlet hole (221) for allowing the intake chamber (113) to be in fluid communication with the outside so that a compressed gas is fed into the inlet hole (221). A needle tube (4) defines a jet hole (41) for spraying the compressed gas from the needle tube (4) into the intake hole (121). When the compressed gas is delivered from the intake lid (2) into the inner tube body (12), air is drawn into the intake hole (121) to mix with the compressed gas according to Venturi effect.一種進氣裝置,包含一輸氣管、一進氣蓋、一導流罩及一針管。輸氣管包括一外管體及一形成於外管體內的內管體。外管體包括一進氣端及一相反於進氣端的排氣端,並界定出一開口形成於進氣端的進氣空間。內管體由排氣端朝進氣端方向延伸,並具有一形成於排氣端的排氣口,及一形成於排氣口相反端的進氣口。進氣蓋封閉蓋設進氣端並形成一進氣孔。導流罩套設於內管體,並形成一位於進氣口與進氣孔間的定位穿孔。針管穿設於進氣孔與定位穿孔。藉由導流罩的設計,將該針管與內管體的中心軸穩固於同一直線,達到增加氣體輸出流量的目的。1‧‧‧輸氣管11‧‧‧外管體111‧‧‧進氣端112‧‧‧排氣端113‧‧‧進氣空間114‧‧‧進氣通孔12‧‧‧內管體121‧‧‧進氣口122‧‧‧排氣口2‧‧‧進氣蓋21‧‧‧蓋體22‧‧‧凸伸柱221‧‧‧進氣孔222‧‧‧第一插接孔部223‧‧‧第二插接孔部3‧‧‧導流罩31‧‧‧匯流空間32‧‧‧套環部33‧‧‧錐部34‧‧‧端壁部341‧‧‧定位穿孔4‧‧‧針管41‧‧‧噴流孔L‧‧‧中心軸線
