A system including a blowing apparatus with expandable function and an expansion device, comprising:
- the blowing apparatus comprising:
- a control unit, used to identify an operating mode of the expansion device being connected with the blowing apparatus, and generate an identity signal according to the operating mode of the expansion device, and processing signals for the blowing apparatus;
- an electrical interface, electrically connected with the control unit, including one or more electrical pins for electrically connecting to the expansion device;
- a fan unit, electrically connected with the control unit, used to control a rotating speed according to the identity signal generated by the control unit;
- a heating unit, electrically connected with the control unit, used to control a temperature according to the identity signal;
- a switch unit, electrically connected with the control unit, used for manually switching multiple operating modes of the expansion device;
- and
- a display unit, electrically connected with the control unit, used to indicate operating status of the blowing apparatus;
- the expansion device applied to the blowing apparatus, comprising:
- a first connection interface configured to have one or more contact pins corresponding to one or more electrical pins of the blowing apparatus, and a locking member with respect to a connecting structure of the blowing apparatus;
- and
- an identification unit, electrically connected with the one or more contact pins of the first connection interface, used to record the operating mode of the expansion device, and allow the control unit of the blowing apparatus to identify the operating mode of the expansion device;
- wherein, while the expansion device is connected to the blowing apparatus, the control unit of the blowing apparatus acknowledges the operating mode of the expansion device from the identification unit, and the control unit automatically controls the rotating speed of the fan unit of the blowing apparatus, and/or the temperature of the heating unit according to the identified operating mode of the expansion device;
- wherein, a power-supply unit of the blowing apparatus is electrically connected with the one or more contact pins of the first connection interface of the expansion device, and the expansion device obtains electric power from the blowing apparatus;
- wherein the expansion device is a mist-type expansion device including a mist unit, a container and a mist generating unit, and is powered by the power-supply unit that allows the mist generating unit to generate mist, sucked by blowing air and mix with air, spray out of an outlet can of the mist-type expansion device by vibrating liquid in the container;
- wherein the operating mode of the mist-type expansion device is a steam iron mode, a hair-moisturizing mode, a steam-beauty mode, or a humidifying mode.
