In this embodiment, the left and right sides of the periphery of the casing body 1 each have two perforations 14, and the perforations 14 are suitable for allowing the elastic strap 6 to pass through the casing body 1.

Referring to Fig. 4, the difference between the second embodiment of the new combined three-dimensional mask and the first embodiment lies in the position of the filter layer 2, and in the second embodiment, the hollow top stopper 5 is omitted. In this embodiment, the filter layer 2 is detachably covered on the outside of the hollow base 131, and the fixing member 3 is also detachably assembled and combined with the hollow base 131. The surrounding wall 32 of the fixing member 3 faces the hollow base 131. The end edge of the seat 131 presses the filter layer 2 against the outside of the hollow base 131, thereby sandwiching and fixing the filter layer 2 between the fixing member 3 and the hollow base 131.

Referring to FIGS. 5 to 7, the third embodiment of the combined three-dimensional mask of the present invention is different from the first embodiment in that the housing body 1 of the third embodiment also includes a valve mounting portion 15 and is combined The three-dimensional mask also includes an exhalation valve group 16. In this embodiment, the valve mounting portion 15 is located above the filter layer mounting portion 13 and roughly corresponds to the position of the nose of the wearer, and the valve mounting portion 15 includes an air hole 151 penetrating through the housing body 1 and adjacent to the air hole 151 provided in the housing The first engaging member 152 of the outer side surface 12 of the main body 1. The exhalation valve assembly 16 includes a valve plate 161 and a valve cover 162. The valve plate 161 is positioned on the outer side surface 12 of the housing body 1 and is used to cover the air hole 151 of the valve mounting portion 15, and the area of the valve plate 161 is larger than the air hole The cross-sectional area of 151 is such that the surrounding area of the valve plate 161 overlaps the outer surface 12 of the casing body 1. The valve cover 162 is coupled to the outer side surface 12 of the casing body 1 and is used to cover the valve plate 161. In this embodiment, the valve cover 162 includes a cover plate 163 in an upright direction, a side wall 164 that extends laterally with respect to the cover plate 163 and faces the casing body 1, and a second engaging member 165 disposed on the cover plate 163 , And the side wall 164 is formed with an opening 166, and the valve cover 162 is coupled to the outer surface 12 of the housing body 1 by the second engaging member 165 being engaged with the first engaging member 152 of the housing body 1, and at this time, The cover plate 163 faces the air hole 151 of the valve mounting portion 15 at intervals. In this embodiment, the first engaging member 152 and the second engaging member 165 are configured to include a rib (not shown) protruding from the outer side surface 12 of the housing body 1, a protruding post and a protrusion provided on the valve cover. The structure of the card slot (not shown in the figure) and the post hole of the 162 is combined, but the manner in which the valve cover 162 is combined with the housing body 1 is not limited to this, as long as it can be installed and combined and can be detached.

With the arrangement of the exhalation valve group 16, when the wearer inhales through the nose, since the valve plate 161 covers the air hole 151 and the area of the valve plate 161 is larger than the cross-sectional area of the air hole 151, the valve plate 161 will be caused by the negative pressure. The surrounding part overlapping the outer side surface 12 of the casing body 1 is more closely attached to the outer side surface 12 of the casing body 1, so that the air holes are more closed to prevent the dirty air from entering through the air holes 151 of the valve mounting part 15. This can be avoided The wearer breathes the dirty air from the outside; and when the wearer exhales from the nose, the valve plate 161 is pushed out by the airflow, and the air hole 151 can be opened so that the exhaled air can pass through the air hole 151 and the opening of the valve cover 162 smoothly 166 outflow. Therefore, the exhalation valve group 16 functions as a one-way valve, restricting the unidirectional flow of gas from the inner side 11 of the casing body 1 to the outer side 12. In addition, in this embodiment, the valve plate 161 is made of, for example, flexible rubber, and includes an upper half and a lower half. The upper half is fixed to the valve mounting portion 15, and the lower half can be mounted by the valve. The portion 15 is lifted away, and the valve plate 161 is arranged in an inclined direction in which the lower half is closer to the valve cover 162, and the opening 166 of the valve cover 162 corresponds to the lower half of the valve plate 161.

Therefore, in the third embodiment of the present invention, the filter layer 2 and the exhalation valve set 16 are arranged in cooperation to control that the inhaled gas can only enter through the filter layer 2, which can prevent the wearer from inhaling unfiltered air from outside and exhaling The gas can be exhaled by the valve installation part 15 without being blocked in the casing body 1.

In addition to the foregoing embodiments, in other variations, the fixing member 3 may also be a buckle formed on the casing body 1 or another structure capable of directly fixing the filter layer 2 thereon.

In summary, through the setting of the ring body 4, the new combined three-dimensional mask can take into account the air-tightness and the comfort of the wearer, and because the ring body 4 is detachable, after wearing for a long time, It can be removed for cleaning or replacement according to the situation, and the casing body 1 can still be used continuously, thus achieving the effect of maintaining the cleaning quality and prolonging the service life of the entire mask. The material of the casing body 1 mentioned above is relatively easy to use. It has greater flexibility and can reduce manufacturing costs, and other components such as the filter layer 2 can also be disassembled, cleaned or replaced, so it can indeed achieve the purpose of new cost. In addition, the filter layer 2 is also removable. Furthermore, this case can control the path of the wearer's exhalation and inhalation through the setting of the exhalation valve group 16, which not only ensures that unfiltered outside air is not inhaled, but also that the exhaled air is not retained. Stagnation in the housing body 1.
