A first breathing tube and a second breathing tube are fixedly installed on both sides of the mask body. The end is fixedly connected with a fixed rope, the upper end of the processing seat is fixedly installed with a first connecting seat and a second connecting seat, the first connecting seat is located on one side of the second connecting seat, the first breathing tube and the first connecting seat A first connecting pipe is connected between the connecting seats, and a second connecting pipe is connected between the second breathing pipe and the second connecting seat; a motor and a first hydraulic cylinder are fixedly installed inside the processing seat near the middle. and the second hydraulic cylinder, the motor is located between the first hydraulic cylinder and the second hydraulic cylinder, and the first hydraulic cylinder is located on one side of the second hydraulic cylinder; various aspects disclosed in the present invention can solve the The problem of dynamic adjustment between the air condition and the breathing condition, and the problem of poor dustproof effect.

Description

technical field [0001] The invention relates to the technical field of masks, in particular to a dust-filtering air-supply type dustproof mask. Background technique [0002] Dust masks are essential protective equipment for workers engaged in and exposed to dust. It is mainly used in working environments containing low concentrations of harmful gases and vapors and in working environments that generate dust. Only adsorbent or sorbent is contained in the poison filter box. Some filter boxes are also equipped with a filter layer, which can prevent aerosols at the same time. Some military gas masks are mainly made of activated carbon cloth, or use water-resistant and oil-resistant fabric as the outer layer, glass fiber filter material as the inner layer, and polyurethane foam soaked in activated carbon as the bottom layer, which can provide temporary protection against sudden poisonous gas attacks. protection. [0003] Patent Publication No. CN111068197A discloses dust-filt...
