The invention relates to an intake device. The intake device comprises an intake pipe, a first resonant cavity, a second resonant cavity, a first connecting pipe and a second connecting pipe, whereinthe first connecting pipe enables the intake pipe and the first resonant cavity to communicate, and the second connecting pipe enables the intake pipe and the second resonant cavity to communicate. The intake device is characterized in that the first connecting pipe is detachably connected with the first resonant cavity, the second connecting pipe is detachably connected with the second resonant cavity, the first connecting pipe is connected with the first resonant cavity in a welded mode, and the second connecting pipe is connected with the second resonant cavity in a welded mode. The intakedevice can better reduce the noises, the occupied space of the whole intake device is reduced, and the structure is more compact.
