Abstract

The invention discloses a breath-synchronized powered air supply type breathing mask which comprises a dust filtration box, a mouth-nose mask, a head fixing assembly, an exhalation valve assembly and an air supplier assembly, wherein the mouth-nose mask comprises a mask body part, a support shell part and a mouth connection assembly, the support shell is connected to the center of the mask body, the mouth connection assembly is arranged on the support shell, and the mouth-nose mask is further provided with air intake holes; the exhalation valve assembly is arranged in the support shell of the mouth-nose mask, and is mainly composed of a top cover, a base, a photoelectric sensor, a control sensing circuit board and a breath directional valve plate; the top cover is fixed on the base, the top cover is provided with exhalation holes, the breath directional valve plate is connected with the top cover, and the photoelectric sensor and the control sensing circuit board are arranged in the base; and the air supplier assembly is arranged in the support shell of the mouth-nose mask and positioned between the exhalation valve assembly and the mouth-nose mask, and a motor output line of the air supplier assembly is connected with the photoelectric sensor on the exhalation valve assembly. The invention improves the use comfort, safety and reliability of the breathing mask.

Description

technical field [0001] The invention belongs to the technical field of a half-mask type personal dust-proof breathing mask, and mainly relates to a breath-following electric air-supply breathing mask. Background technique [0002] Personal breathing masks are mainly used in tunnels, workshops and other places where there are often large dust and smoke, and are used to protect the personal respiratory system. Personal breathing masks generally consist of the following parts: mask body, air filter, and air directional valve. The main body of the mask is mainly used to form a well-air-tight space between the mask and the user's mouth and nose to prevent dust and other harmful media from entering the mouth and nose; the air filter is the only channel for air to enter the mask, and has the ability to filter and remove dust. Function; the air directional valve is mainly used for shunting the gas inhaled and exhaled by the user. Traditional personal breathing masks are mostly sel...
