Figures 1-2 In this embodiment of the present invention, a universal mobile phone screen protector dust-free chamber includes: a frame body 1 consisting of a base substrate 12 and a positioning ring edge 11 arranged along the edge of the base substrate 12. The frame body 1 has a semi-enclosed structure to form a screen protector cavity 14. A main cover plate 13 is also provided on one side of the frame body 1. The main cover plate 13 can be flipped to cover the screen protector cavity 14 of the frame body 1. The lower edge of the frame body 1 is formed with a tear strip hole 111 that communicates with the film application cavity 14, and a pair of film application positioning posts 122 are also provided in the film application cavity 14. During the screen protector application process, the phone is placed upside down in the screen protector cavity 14, such as... Figure 3 The screen protector 3 shown has a three-layer structure, including a main film 31, a front protective film 32 and a release film 33 protecting the main film 31. The release film 33 has a peel-off adhesive strip 331 formed on it. When applying the screen protector, the screen protector is placed in the screen protector cavity 14 beforehand. The top of the front protective film 32 extends outward and has a screen protector positioning hole 321 that can be fitted onto the screen protector positioning post 122 to position the screen protector 3. The peel-off adhesive strip 331 passes through the peel-off strip hole 111. Then, the main cover plate 13 flips over and covers the screen protector cavity 14 of the frame main body 1, pressing down on the back of the phone. The release film 33 is peeled off from the main film 31 by pulling out the peel-off adhesive strip 331, while absorbing fine dust on the screen, so that the main film 31 is adhered to the phone, and the screen protector application is completed.
[0017] In order to enable the phone to be accurately positioned in the film-applying cavity 14, a phone positioning component is provided in the film-applying cavity 14 to limit the phone's position.
