Power supply device with humidifying function

Abstract

A power supply device with a humidifying function includes a body, a circuit board, and a heater. An accommodation space is defined inside the body, and a water reservoir is disposed inside the accommodation space for storing water. A steam vent is formed on a surface of the body for communicating the water reservoir. The circuit board is disposed on a bottom of the accommodation space and includes an input connector and an output connector disposed thereon. The circuit board receives an external power from the input connector, transforms the external power into a first output power and outputs the first output power via the output connector, or transforms the external power into a second out power. The heater is electrically connected to the circuit board and contacts the water reservoir, for receiving the second output power for the purpose of heating water and vaporizing the water into steam.

1 . A power supply device with a humidifying function, storing water for the purpose of vaporizing water to steam, comprising:
 a body, comprising an accommodation space defined therein, a water reservoir disposed inside the accommodation space for storing water, and a steam vent formed on a surface of the body for communicating the water reservoir;   a circuit board, disposed on a bottom of the accommodation space, and an input connector and an output connector being disposed on the circuit board; the circuit board receiving an external power from the input connector, selectively transforming the external power into a first output power or a second output power, and outputting the first output power via the output connector;   a power input cable, having one end connected to the input connector and another end equipped with a first power jack for receiving the external power;   a power output cable, having one end connected to the output connector and another end equipped with a second power jack for outputting the first output power; and   a heater, electrically connected to the circuit board and contacting to the water reservoir, for receiving the second output power to heat the water in the water reservoir.   
     
     
         2 . The power supply device with a humidifying function as claimed in  claim 1 , further comprising a sealing cover detachably combined with the body for sealing the steam vent. 
     
     
         3 . The power supply device with a humidifying function as claimed in  claim 1 , wherein the first power jack is a household power plug. 
     
     
         4 . The power supply device with a humidifying function as claimed in  claim 1 , wherein the circuit board further comprises a voltage converter for selectively transforming the external power into the first output power or the second output power. 
     
     
         5 . The power supply device with a humidifying function as claimed in  claim 1 , wherein the second power jack is a direct current power jack. 
     
     
         6 . The power supply device with a humidifying function as claimed in  claim 1 , further comprising a switch disposed on the body and electrically connected to the circuit board, for controlling the circuit board to output the first output power or the second output power. 
     
     
         7 . The power supply device with a humidifying function as claimed in  claim 6 , further comprising a switch cover movably jointed to the body, for selectively covering the switch.
