Title:
RESPIRATION EQUIPMENT
Document Type and Number:
Japanese Patent JP3726886
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide respiration equipment which suppresses the increase of the consumption of filtration material and power consumption, reduces exhalation resistance, and simplifies structure to be hardly broken.
SOLUTION: At the front part of a face body 2, an exhalation valve 7 which opens in exhalation and closes in inhalation and an inhalation valve 8 closing in exhalation and opening in inhalation are provided and a blower 16 which is driven by a motor 9 for feeding outside air into the face body through the valve 8 on its normal operation is provided. A sensor 11 sensing moving of the valve 7 and the valve 8 and outputting a signal in exhalation or inhalation is installed to supply power to the motor 9 so as to operate normally in inhalation and to stop or reduce power supply to the motor 9 in exhalation according to the signal from the sensor 11.
