DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present invention.
Referring to FIG. 2, a gauze mask, which can be worn with one hand in accordance with a first embodiment of the present invention, comprises: a mask body 10, a nose clip member 20, and a chin pressing member 30. The mask body 10 is an arc-shaped structure with an outward expanding opening 11, and a covering space 12 which is formed in the opening 11 to cover wearer's mouth and nose. The covering space 12 allows for air exchange between the inside and outside of the mask body 10. At the top portion and bottom portion of the opening 11 of the mask body 10 are formed a support portion to support the user's nose and a hooking portion to be hooked to the user's nose, respectively, which enables the mask body 10 to be positioned quickly to the mouth and nose of the user. Around the inner periphery edge of the opening 11 of the mask body 10 is disposed an adhesive layer 13 which creates an adhesive force at the upper inner edge and lower inner edge of the opening 11 and provides an adhesive force F0 toward the user's face. The nose clip member 20 is disposed at the center of the top portion of the opening 11, and provided at two ends thereof with two clipping portions 21 to be abutted against two lateral sides of the user's nose, which provides an upper pressing force F1. The chin pressing member 30 is disposed at the bottom portion of the mask body 10 to be abutted against the user's chin, so as to produce a lower pressing force F2 with respect to the user's chin.
The two clipping portions 21 are connected by an elastic connecting portion 40 which provides a prestress to push the two clipping portions 21 toward each other, so that the two clipping portions 21 can be clamped against two lateral sides of the user's nose to produce two lateral clamping forces. With the upper and lower pressing forces F1, F2, which are produced by the nose clip member 20 and the chin pressing member 30, respectively, and applied in opposite directions to the user's nose and chin, plus the two lateral clamping forces, the gauze mask of the present invention can be quickly and easily worn with one hand, and the periphery edge of the opening 11 of the mask body 10 can be closely abutted against the user's mouth and nose in an airtight manner.
The reason why the covering space 12 allows for air exchange between the inside and outside of the mask body 10 is because the mask body 10 is a breathable structure which is made of non-woven material, or high-density fabric layer or paper.
Referring to FIGS. 3 and 4, a gauze mask which can be worn with one hand in accordance with a second embodiment of the present invention is similar to the first embodiment, except that: the structure allowing for air exchange between the inside and outside of the mask body 10 is a ventilation hole 50 which is formed at the center of the elastic connecting portion 40, and more specifically, the ventilation hole 50 is formed at an extension portion 41 extending from the center of the elastic connecting portion 40 toward the user's nose and mouth. The ventilation hole 50 is covered with a filter 60 which includes a hollow frame 51 and a filter layer 61 disposed in the hollow frame 51, and the filter layer 61 is fabric layer or a composite layer or a paper layer which contain catalyst or activated carbons.

The ventilation hole 50 is covered with a filter 60 which includes a hollow frame 51 and a filter layer 61 disposed in the hollow frame 51, and the filter layer 61 is fabric layer or a composite layer or a paper layer which contain catalyst or activated carbons.
FIG. 6 is a perspective view showing that the gauze mask in accordance with the first embodiment of the present invention is put on the face. The chin pressing member 30 is a little elastic to elastically clamp against the user's chin. The two clipping portions 21 are connected by the elastic connecting portion 40, so that the two clipping portions 21 can be clamped against two lateral sides of the user's nose to produce two lateral clamping forces. The adhesive layer 13 provides an adhesive force F0 toward the user's face.
FIG. 7 is a side view showing that the gauze mask in accordance with the first embodiment of the present invention is put on the face. The upper pressing force F1 produces a downward pressing force on the user's nose, and the lower pressing force F2 is an upward pressing force applied to the user's chin, and the upper and lower pressing forces F1, F2 are combined into a clamping force. The adhesive layer 13 provides an adhesive force F0 around the user's mouth and nose. Hence, the gauze mask of the present invention can be quickly and easily put on the user's face with only one hand.
FIG. 8 is a perspective view showing that the gauze mask in accordance with the third embodiment of the present invention is put on the face. The gauze mask covers the user's nose and mouth in such a manner that the two clipping portions 21 are clamped closely against two lateral sides of the user's nose, and the chin pressing member 30 is pressed tightly against the user's chin. The adhesive layer 13 is made of adhesive gelatinous or non-gelatinous material, and covered with a release film. The adhesive layer 13 is located around the opening and adhered to the user's nose and mouth, and the filter 60 acts as an air exchanger.
Referring to FIG. 9, a gauze mask, which can be worn with one hand in accordance with a fourth embodiment of the present invention, comprises: a mask body 10, a nose clip member 20, and a chin pressing member 30. The mask body 10 is an arc-shaped structure with an outward expanding opening 11, and a covering space 12 which is formed in the opening 11 to cover wearer's mouth and nose. The covering space 12 allows for air exchange between the inside and outside of the mask body 10. At the top portion and bottom portion of the opening 11 of the mask body 10 are formed a support portion to support the user's nose and a hooking portion to be hooked to the user's nose, respectively, which enables the mask body 10 to be positioned quickly to the mouth and nose of the user. Around the inner periphery edge of the opening 11 of the mask body 10 is disposed an adhesive layer 13 which creates an adhesive force at the upper inner edge and lower inner edge of the opening 11, and also provides an upper pressing force F1 and a lower pressing force F2 to press against the user's chin.
Referring then to FIGS. 10 and 11, which are a side view and a lateral cross sectional view of FIG. 9, the mask body 10 can be folded into a flat configuration and includes at least two foldable portion 14. There are three foldable portions 14 in this embodiment, each of the foldable portions 14 includes a first folding line 140 and a second folding line 141, and at least one of the foldable portion 14 further includes at least two overlapping areas 142, which is located between the first and second folding lines 140, 141, and a middle folding line 143 between the two overlapping areas 142. When the overlapping areas 142 are flatly overlapped with each other, as shown in FIGS. 10 and 11, the mask body 10 is folded into a flat configuration for easy storage. When the overlapping areas 142 are pulled out from each other, as shown in FIG. 9, the mask body 10 will be unfolded into a three dimensional configuration which is provided with the outward expanding opening 11, and the covering space 12 which is formed in the opening 11 to cover wearer's mouth and nose.
