A ventilating device includes a rectangular frame, a louver, an adapter, a helix shell and a circuit board box. A mounting base at a bottom surface of the helix shell is configured for installation of a plurality of functional units thereon. The mounting base is provided with a base circuit board for interfacing with the functional units, and the circuit board box is coupled to the mounting base by a lead wire. Both the circuit board box and the mounting base include a hole, through which the lead wire passes. These holes are arranged in a linear manner in an up-down direction arranged at the side towards an air outlet. The plurality of functional units are configured to be freely assembled or disassembled individually to or from the mounting base. |
