A shaping frame is arranged at the edge of the mouth open hole. Two sides of the shaping frame are both equipped with T-shaped sliding grooves in vertical direction. Sealing covers, matching the mouth open hole in terms of size, are arranged in theT-shaped sliding grooves. Upper ends of the sealing covers are fixed at the upper part of the shaping frame. Two sides of each sealing cover are respectively embedded into the corresponding T-shapedsliding grooves. Lower ends of the sealing covers are fixedly equipped with shaping rods so that open hole size of the mouth open hole is convenient to adjust. Therefore, different groups of people can be suitable for the dustproof mouth mask. The dustproof mouth mask enjoys good adaptability and sealing performance and is convenient in operation and simple in structure and highly comfortable. When an insert rod locks the nose mask, the opening size of the mouth open hole is adjusted. The dustproof mouth mask is simple in structure and diverse in functions. The nose mask is hinged onto the mouth mask body. When not in use, the dustproof mouth mask can be folded, thereby saving accommodation space. The dustproof mouth mask is convenient to carry.
