The mask body is formed with a covering space to cover user's mouth and nose. Around the inner periphery edge of an opening of the mask body is disposed an adhesive layer which enables the gauze mask to be adhered around the user's nose and mouth. The nose clip member and the chin pressing member allow the gauze mask to be firmly positioned on the user's face. The gauze mask is made of breathable material, or the gauze mask can also be made of non-breathable material but is equipped with a filter, so as to allow for air exchange between inside and outside of the gauze mask. ## Claims ### Claim 1 A gauze mask which can be worn with one hand, comprising: a mask body being an arc-shaped structure including an outward expanding opening, and a covering space which is formed in the opening and configured to cover user's mouth and nose, the covering space allowing for air exchange between inside and outside of the mask body, at a top portion and a bottom portion of the opening of the mask body being formed a support portion adapted to support the user's nose and a hooking portion adapted to be hooked to the user's nose, respectively, around an inner periphery edge of the opening of the mask body being disposed an adhesive layer which creates an adhesive force at an upper inner edge and a lower inner edge of the opening; wherein a nose clip member is disposed at a center of the top portion of the opening, and is provided with two clipping portions and an elastic connecting portion connected between the two clipping portions, the two clipping portions are configured to be abutted against two lateral sides of the user's nose to provide an upper pressing force with respect to the user's nose, the elastic connecting portion provides a prestress to push the two clipping portions toward each other, so that the two clipping portions are capable of clamping against two lateral sides of the user's nose to produce two lateral clamping forces, and a periphery edge of the opening of the mask body is capable of pressing against the user's mouth and nose in an airtight manner. ### Claim 2 (depends on 1) The gauze mask which can be worn with one hand as claimed in claim 1, wherein the mask body is a breathable structure which is made of non-woven material, or high-density fabric layer or paper, so that the covering space allows for air exchange between the inside and outside of the mask body. ### Claim 3 (depends on 2) The gauze mask which can be worn with one hand as claimed in claim 2 further comprises a chin pressing member disposed at a bottom portion of the mask body and adapted to be abutted against the user's chin, so as to produce a lower pressing force with respect to the user's chin. ### Claim 4 (depends on 1) The gauze mask which can be worn with one hand as claimed in claim 1, wherein a structure allowing for air exchange between the inside and outside of the mask body is a ventilation hole which is formed at a center of the elastic connecting portion, the ventilation hole is covered with a filter which includes a hollow frame and a filter layer disposed in the hollow frame, and the filter layer is a fabric layer or a composite layer or a paper layer which contain catalyst or activated carbons. ### Claim 5 (depends on 1) The gauze mask which can be worn with one hand as claimed in claim 1, wherein a structure allowing for air exchange between the inside and outside of the mask body is a ventilation hole which is formed at an extension portion extending from a center of the elastic connecting portion toward the user's nose and mouth, the ventilation hole is covered with a filter which includes a hollow frame and a filter layer disposed in the hollow frame, and the filter layer is a fabric layer or a composite layer or a paper layer which contain catalyst or activated carbons. ### Claim 6 (depends on 1) The gauze mask which can be worn with one hand as claimed in claim 1, wherein the chin pressing member is elastic and adapted to elastically clamp against the user's chin. ### Claim 7 (depends on 1) The gauze mask which can be worn with one hand as claimed in claim 1, wherein the adhesive layer is made of adhesive gelatinous or non-gelatinous material, and covered with a release film. ### Claim 8 (depends on 1) The gauze mask which can be worn with one hand as claimed in claim 1, wherein the adhesive layer provides an adhesive force to adhere the gauze mask to the user's face in an aright manner. ### Claim 9 (depends on 1) The gauze mask which can be worn with one hand as claimed in claim 1, wherein the mask body is capable of being folded into a flat configuration and includes at least one foldable portion, and the at least one foldable portion includes a first folding line and a second folding line, at least two overlapping areas between the first and second folding lines, and a middle folding line between the two overlapping areas.
