[Object of the Invention] An object of the present invention is to provide a breathing apparatus comprising a face piece for covering the whole face of a user, and a fan unit for operating synchronously with the breath timing of the user, wherein the breathing apparatus comprises a breath monitoring apparatus provided with a diaphragm and a sensor for detecting movement of the diaphragm, and wherein the location of the diaphragm and the sensor is optimized and a transmission path of inhale pressure and exhale pressure to the diaphragm is optimized. [Disclosure of the Invention] A breath monitoring apparatus comprising a diaphragm and a sensor for detecting movement of the diaphragm is disposed in a fan unit, a space for accommodating the diaphragm and the sensor is disposed independently of an air passage in the fan unit, and the internal space of a nose cup is communicated with the space in the fan unit through a hole formed in the nose cup and a hole formed in the face piece when the fan unit and the nose cup are connected to the face piece.
A breathing apparatus comprising a filter, a fan unit, a face piece for covering the whole face of a user, a nose cup for covering the mouth and the nose of the user, and a breath monitoring apparatus, wherein the filter is detachably connected to the fan unit, the fan unit is detachably connected to the face piece from the outside of the face piece, the nose cup is detachably connected to the face piece from the inside of the face piece, and the fan unit operates synchronously with the breath timing of the user detected by the breath monitoring apparatus, and wherein the breath monitoring apparatus comprises a diaphragm and a sensor for detecting movement of the diaphragm, the breath monitoring apparatus is disposed in the fan unit, an air passage and a space independent of the air passage for accommodating the diaphragm and the sensor are formed in the fan unit, a hole is formed in the face piece to communicate with the space in the fan unit when the fan unit is connected to the face piece, a hole is formed in the nose cup to communicate with the hole in the face piece when the nose cup is connected to the face piece, and the internal space of the nose cup communicates with the space in the fan unit through the hole in the nose cup and the hole in the face piece when the fan unit and the nose cup are connected to the face piece.
