The three dimensional non-woven face ensures a good air tightness against the face while leaving a large enough space between the three dimensional cup and the nose and mouth area to ensure conformable wearing, good filtration, making the wearer easy to breathe and talk.

The invention provides a folding bench, belongs to the technical field of furniture, and solves the problems that the conventional folding bench is larger in occupied space after being folded, heavier in weight and inconvenient to carry. The folding bench comprises a seat plate, a chair back and at least two sets of chair legs, wherein the chair back is hinged with the rear edge part of the seat plate; a limiting structure at least capable of preventing the chair back from rotating backwards is arranged between the chair back and the seat plate; the chair legs are all hinged with the bottom surface of the seat plate; and a fixing structure capable of fixing the chair legs when the chair legs are used for supporting the seat plate is arranged between each chair leg and the seat plate. The folding bench is simpler in structure, convenient to operate, smaller in volume after being folded, also smaller in space required to be occupied, lighter in weight and convenient to carry.

The invention provides a public chair in scenic spots, and belongs to the technical field of public facilities. The problem that the function of an existing public chair is single is solved. The public chair in the scenic spots comprises two chair bodies, each chair body comprises a backrest, a chair plate, a base plate, and a front side plate and a rear side plate which are connected with the base plate, one end of the front side plate is connected with the chair plate, one end of the rear side plate is connected with a table plate, two baffle bars which are parallel to each other are arranged on the chair plate, the ends, far away from the front side plate, of the baffle bars are hinged to the backrest, and the backrest can rotate along the hinge parts to make the backrest abut against the table plate in an inclined mode or make the backrest horizontally attached to the chair plate; the public chair comprises the chair bodies which are arranged side by side and connected with each other through a rotating shaft, and the two chair bodies can rotate along the rotating shaft to make the chair bodies be in horizontal mirror symmetry or in vertical mirror symmetry. The backrests rotate along the hinge parts to make the backrests horizontally attached to the corresponding chair plates, the table plates are utilized to serve as tables, or the chair bodies are made to be in horizontal mirror symmetry by rotating along the rotating shaft, and users can sit face to face.

The invention provides a mask advantaged by prevention of a filtering liner installed on the mask from contacting mouth of a wearer, prevention of stuffed humidity, easy breathing, easy talk, and prevention of obscuring glasses lenses during wearing of glasses users.
