The present invention discloses a method for manufacturing a protective cover, comprising: providing a transparent substrate 100, and holes 101 are respectively provided on two sides of the transparent substrate 100, which are one hole 101 and four holes (1011, 1012, 1013 and 1014), respectively, And the transparent substrate 100 has a first surface 1 and a second surface 2, wherein the first surface 1 is facing the human face, the first surface 1 is coated with an anti-fog film, and the second surface 2 is coated with a functional coating. layer; forming a foam body 200 on the transparent substrate 100, the foam body has a plurality of notches 201 and an attaching surface 202, the foam body 200 is adhered to the transparent substrate 100 through an adhesive layer 102 ; And wear an elastic band 300, one end A of the elastic band 300 is fixed in the one hole 101, the other end B of the elastic band 300 is worn through the four holes (1011, 1012, 1013 and 1014) to form a movable end thereby Adjust the length of the elastic band, wherein, the four holes ( 1011 , 1012 , 1013 and 1014 ) on the transparent substrate 100 are sequentially arranged from the edge to the inside as a first hole 1011 , a second hole 1012 , and a third hole. 1013 and a fourth hole 1014, the movable end of the elastic band 300 penetrates the two holes 1012 from the first surface 1 facing the user's face and passes through the second surface 2, and then passes through the third hole 1013 Enter and return to the first surface 1, then pass through the fourth hole 1014 to the second surface 2, then pass through the second hole 1012 back to the first surface 1, and finally pass through the first hole 1011 to the second surface 2 .

Referring to FIG. 6 , the elastic band 300 of the protective cover of the present invention has a fixed end on one side and a movable end on the other side, allowing the user to adjust the length of the elastic band of the mask to suit the size of the user's head circumference. Furthermore, the four holes (1011, 1012, 1013 and 1014) designed at the active end have been painstakingly researched and developed for many times. If there is only one hole at the end of the protective cover to adjust the length, it is usually because the elastic band needs to be provided with a female button for more coordination. A male button is used to achieve the purpose of adjusting the length, but because the male and female buttons are set to be fixed, the length that can be adjusted can only have several changes in length, and the insufficient or excessive length is made up by the elasticity of the elastic band itself. , but after wearing it for a long time, the user will cause facial indentation or the mask will be easily loosened due to the inappropriate size.

Referring to FIG. 6, if two holes (1012 and 1013) are provided at one end of the protective cover for adjusting the length, although the two holes can achieve the purpose of adjustment, it is easy to slide and loosen, which makes the adjustment end difficult to fix the length of the elastic band. If three holes (1012, 1013 and 1014) are provided at one end of the protective cover to adjust the length, the adjustment purpose can be achieved and the problem of loosening can be solved. It can be seen that the elastic band 300 has two holes 1012 through the hole 1012 at the same time. When the length of the elastic band is short, the fulcrum of the force is in the hole 1012, and at the same time, two elastic bands 300 pass through the hole 1012 and move in opposite directions to generate frictional force, so the adjustment of the length will be very unsmooth. If there are four holes (1011, 1012, 1013 and 1014) at one end of the protective cover to adjust the length, when the elastic band is to be adjusted, the fulcrum of the force is in the hole 1011, and only one elastic band 300 passes through the hole, and the adjustment is relatively smooth. In addition, it can also achieve the purpose of fixing the length.

However, the above are only preferred embodiments of the present invention, and should not limit the scope of the present invention, that is, any simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the contents of the description of the invention, All still fall within the scope of the patent of the present invention.
