An intake module includes an outer tube body defining an intake chamber and having an intake end, and an inner tube body disposed in the outer tube body and having an intake hole communicating with the intake chamber. An intake lid covers the intake end and has an inlet hole for allowing the intake chamber to be in fluid communication with the outside so that a compressed gas is fed into the inlet hole. A needle tube defines a jet hole for spraying the compressed gas from the needle tube into the intake hole. When the compressed gas is delivered from the intake lid into the inner tube body, air is drawn into the intake hole to mix with the compressed gas according to Venturi effect.
