Please refer to Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, which are the three-dimensional appearance diagram, front view, three-dimensional exploded view and schematic diagram of the preferred embodiment of this creation, which can be seen from the figure It can be clearly seen that the protective filter mask 1 of this creation mainly includes: a transparent cover 2; a filter base 3, which is arranged on one side surface of the transparent cover 2, and the filter base 3 is also provided with a window opening 30, and The bottom of the window opening 30 is extended to form a lower covering part 31, and the upper part is extended to form an upper covering part 32; a plurality of hot-melt lines 4 are arranged on the filter base 3, so that the filter base 3 is combined with other parts of the transparent cover 2 One side surface; wherein, the upper cladding portion 32 is additionally provided with a fixing piece 321; wherein, two corresponding side edges of the filter base 3 are respectively provided with an elastic rope body 33;

When the protective filter mask 1 of the present invention is worn, as shown in the figure, the lower covering part 31 and the upper covering part 32 are first turned outwards, so that the window opening 30 of the filter base body 3 is completely exposed, and the continuous use The lower covering part 31 covers the wearer's chin, while the upper covering part 32 is attached to the forehead, and finally the two elastic cords 33 of the corresponding side edges of the filter matrix 3 are hung on the ears, and the wearer can use The protective filter mask 1 covers the entire face of the wearer;

In view of the above, when the upper covering part 32 is attached to the forehead, the angle of the fixing piece 321 provided on it can be adjusted to make the upper covering part 32 match the curvature of the forehead, thereby increasing the tightness of the upper covering part 32. When the lower covering part 31 covers the wearer's chin, the upper covering part 32 is pasted behind the forehead, and the two elastic cords 33 are hung on the ears, the window opening 30 can be adjusted accordingly. In the wearer's eyes, nose and mouth so that others can see the wearer's eyes, nose and mouth;

In addition, after the protective filter mask 1 is worn, in addition to carrying out the first layer of protection through the transparent cover 2, when the wearer is breathing, he can pass through the lower covering part 31 and the upper covering part 32 to Filtering, that is to say, the protective filter mask 1 provides the protection of the wearer's face and the effect of respiratory filtration;

In addition, since the transparent cover 2 is located on the outermost side when wearing it, in addition to preventing external droplets, dust and foreign matter from contaminating the wearer's face, the protection of the transparent cover 2 can also prevent external damage The filter matrix 3, and the transparent cover 2 increases the strength of the whole and thus increases the service life;

In addition, the reason why the eyes, nose and mouth of the wearer need to correspond to the window opening 30 of the filter base 3 is not only to make the protective filter mask 1 correctly cover and protect the eyes, nose and mouth, but also Allows others to clearly see the wearer's eyes, nose and mouth, thereby Increase the feeling of facial expressions when communicating with each other, especially for deaf-mute people, it is easier to read and judge the information of lip language;
