Abstract
A hair dryer includes a main body, a handle, and a diffuser. The diffuser includes a diffusing case having a rear side coupled to the main body. The main body is provided such that a front end of an outer wall surrounds a gas or air outlet, and a first coupling portion coupled with the diffuser is provided at the front end. The diffusing case includes a second coupling portion coupled to the first coupling portion while surrounding a gas or air inlet hole defined at the rear side. The first coupling portion includes a power transmitter to supply power to the diffuser, and the second coupling portion includes a power receiver to receive the power from the power transmitter.
Claims21
A hair dryer, comprising:
- a main body including a front end;
- an outlet provided at the front end through which fluid is discharged;
- a first coupler provided at the front end and surrounding the outlet;
- a power transmitter provided on the first coupler and configured to transmit power;
- a handle extending from the main body;
- and
- a diffuser, including:
- a case having a rear end,
- an inlet provided at the rear end,
- a second coupler provided at the rear end and surrounding the inlet, the second coupler being configured to be removably coupled to the first coupler, and
- a power receiver provided on the second coupler and configured to receive power, wherein, when the first coupler is coupled to the second coupler:
- at least a portion of the rear end of the diffuser surrounds at least a portion of the outlet of the main body,
- the inlet and the outlet are aligned to communicate with each other such that the inlet receives fluid discharged from the outlet, and
- the power receiver is electrically coupled to the power transmitter to receive power transmitted from the power transmitter.
A diffuser for a hair dryer, comprising:
- a case having a rear end;
- an inlet provided at the rear end and configured to receive fluid;
- a coupling sleeve provided at the rear end and surrounding the inlet, the coupling sleeve being configured to be coupled with and removed from a portion of the hair dryer such that the inlet receives fluid discharged from the hair dryer;
- and
- a power receiver provided on the coupling sleeve and configured to receive power, wherein, when the coupling sleeve is coupled to the hair dryer, the power receiver is electrically coupled to a power transmitter provided on the hair dryer, wherein the coupling sleeve includes at least one of:
- a magnet;
- screw threads;
- at least one hook;
- at least one sliding groove;
- or
- at least one protrusion;
- and
- wherein the power receiver is configured to power at least one of:
- a light provided inside of the case and configured to emit light away from the inlet;
- a proximity sensor configured to sense a distance to a target in front of the case;
- or
- a moisture level sensor provided on a front side of the case to measure a moisture level in front of the case.
