| titleOfInvention | A kind of dust mask for building construction |
| abstract | The utility model relates to the technical field of building construction appliances, and specifically discloses a dust mask for building construction, comprising a cover body, a nasal mask is fixedly connected to the center of the top of the cover body, and a soft rubber strip is fixedly connected to the top of the back of the inner wall of the mask. The center of the left and right sides of the cover is fixedly connected with elastic ropes, the top of the back of the cover and the left and right sides close to the center are fixedly connected with sealing gaskets, and the center of the front of the inner wall of the cover is fixedly connected with a large particle filter layer, a large particle filter layer The center of the back is fixedly connected with a dust filter layer, and the center of the back of the dust filter layer is fixedly connected with a sponge contact layer. The skin of the patient is in contact with each other, so that the nasal mask can fit more closely with the skin of the user, thereby preventing dust particles from entering the mask from the nose of the patient. |
