Claims
- 1. A portable dryer comprising:
a housing with an opening at one end thereof; a motor having a fan installed inside the housing; a switch installed inside the housing; a second heating filament; a third heating filament; a fourth heating filament; and a battery electrically coupled to the switch, the motor and the heating filaments for supplying electric power; wherein the switch is capable of being controlled to electrically disconnect all three heating filaments from the motor, to electrically connect the third heating filament with the motor, or to provide a first circuit in parallel with a second circuit, the first circuit comprising the motor in series with a parallel arrangement of the third and fourth heating filaments, the second circuit comprising the second heating filament.
- 2. The portable dryer of claim 1, wherein the switch comprising a conductor and a plurality of connecting nodes, one end of the conductor being pivotally coupled to the switch, and through the connection with the battery via a wire the other end of the conductor being able to get into electrical contact with the plurality of connecting nodes by rotation, so as to electrically disconnect all three heating filaments from the motor, to electrically connect the third heating filament with the motor, or to provide a parallel arrangement of the first circuit and the second circuit.
- 3. The portable dryer of claim 2, wherein the conductor is of an approximately fan shape.
- 4. The portable dryer of claim 1, wherein the switch comprises a displaceable conductor, where the displaceable conductor being able to be shifted to electrically disconnect all three heating filaments from the motor, to electrically connect the third heating filament with the motor, or to provide a parallel arrangement of the first circuit and the second circuit.
- 5. The portable dryer of claim 4, wherein the displaceable conductor has two separate conducting pieces.
- 6. The portable dryer of claim 1, wherein the battery is a rechargeable battery.
