<P>PROBLEM TO BE SOLVED: To provide a mask device with a blower which can scan timing of breathing in high accuracy by eliminating influence of the turbulent flow by an impeller without being enlarged. <P>SOLUTION: A blower 16 to be driven by a motor 9 to feed outside air into a face body 2 in ordinary operation is equipped on this mask device. A breath detecting means 10 to detect whether a condition in the face body 2 is in exhalation or inhalation to transmit signals to the motor 9 is equipped in the vicinity of the blower 16. By a signal from the breath detecting means 10, power is supplied to the motor 9 for ordinary operation in inhalation and reduced or stopped in exhalation. A resistance body 6 to convert the turbulent flow generated by the blower 16 to the laminar flow and pass the laminar flow therethrough is equipped between the breath detecting means 10 and the blower 16. <P>COPYRIGHT: (C)2004,JPO |
