Description

Technical Field

[0001] This invention relates to the field of film application tools, and more specifically, to a silicone book box film applicator and its usage method. Background Technology

[0002] Mobile phone screen protectors, also known as mobile phone protective films or mobile phone beauty films, are thin-layer composite material products that are applied to the surface of mobile phone screens and bodies through adhesive backing or electrostatic adsorption. They are used to provide physical protection or aesthetic decoration for mobile phones. From a material perspective, mobile phone screen protectors are generally divided into three categories based on their main materials: tempered glass films, PET films, and liquid nano films.

[0003] According to existing technology, when manually applying a screen protector without the use of auxiliary tools, it is difficult for users to ensure that the film is aligned with the edge of the screen at the same time, which can easily lead to misalignment or tilting. At the same time, when cleaning the screen in daily environment, it is difficult to completely remove all the tiny dust or fibers. When applying the screen protector, these foreign objects will form obvious air bubbles or white spots because they are pressed under the screen protector, which can easily affect the display effect and the adhesion. Summary of the Invention

[0004] This invention provides a silicone book case screen protector and its usage method. The device uses positioning and limiting blocks inside the case to fix the phone's position. When the cover is closed, a squeezing block and a top block lock the positioning film, preventing misalignment or shaking during application and improving the alignment accuracy between the screen protector and the screen. The layered structure of the pull strap, tape, film, and screen protector allows users to complete the main application process simply by rotating the cover and pulling the pull strap, reducing operational complexity. A dust extraction device uses an airbag, one-way valve, and rubber ring to create localized negative pressure above the screen, absorbing fine dust particles from the glass surface. This solves the problem mentioned in the background section: these foreign objects pressed under the screen protector can form noticeable bubbles or white spots, easily affecting display quality and adhesion.

[0005] To achieve the above objectives, a silicone book box film applicator and its usage method include a box body and a pull strap. A mobile phone is installed inside the box body, and the pull strap is located directly above the mobile phone. Adhesive tape is adhered to the top of the pull strap, a thin film is adhered to the top of the adhesive tape, a protective film is adhered to the top of the thin film, and a positioning film is provided directly above the protective film. A rotating cover is rotatably connected to the outside of the box body, and soft pads are provided at the bottom of the pull strap and the top of the protective film. The top of the mobile phone is equipped with a dust-collecting device for absorbing dust on the surface of the mobile phone glass. The dust-collecting device includes a storage plate set directly above the mobile phone. Three connecting tubes are fixedly connected to the top of the storage plate. A suction tube is fixedly connected to one end of the three connecting tubes away from the storage plate. An air bag is fixedly connected to one end of the suction tube. The storage plate is equipped with a cleaning device for cleaning debris from the glass surface of the mobile phone. The cleaning device includes two connecting blocks that are fixedly connected to both sides of the storage plate. A cleaning roller is rotatably connected inside the two connecting blocks. Multiple brushes are fixedly connected to the outside of the cleaning rollers. The brushes are located directly above the mobile phone. A storage box is fixedly connected to one side of the two connecting blocks.

[0006] In the above technical solution, two positioning blocks are fixedly connected to the inside of the box near the end of the mobile phone, and two limiting blocks are fixedly connected to the inside of the box near both sides of the mobile phone. Two locking posts are fixedly connected to the top of the box, and two locking blocks are fixedly connected to the top of the box. The positioning film is detachably connected to the inside of the two locking posts and the outside of the two locking blocks. A pressing block and a top block are fixedly connected to the inside of the rotating cover. The pressing block has a groove inside that matches the soft pad. When the rotating cover rotates, the rotating cover drives the pressing block and the top block to rotate. The pressing block retracts the soft pad into the groove, and at the same time, the soft pad and the top block press against the top of the positioning film to fix the position of the positioning film.

[0007] Secondly, one-way valves are fixedly installed on the outside of both the straw and the airbag. The two one-way valves have the same exhaust direction, which is used to allow gas to flow from the straw to the airbag and then to the outside. Guide strips are fixedly connected to both sides inside the storage plate, and a rubber ring is fixedly connected to the bottom of the storage plate. The rubber ring is located at the top of the mobile phone.

[0008] Furthermore, based on the above, a positioning component is provided on one side of the box body and the storage plate. The positioning component includes a limiting frame fixedly connected to one side of the box body. A movable block is movably connected to the outside of the limiting frame. One side of the movable block is fixedly connected to one side of the storage plate. A threaded post is threadedly connected inside the movable block. A limiting post is fixedly connected to one side of the threaded post. A limiting strip is fixedly connected to the top of the limiting frame. The limiting post is located inside the limiting strip. A limiting groove is formed inside the limiting strip. The limiting post and the limiting strip are inserted and engaged through the limiting groove.

[0009] Meanwhile, a wire brush is fixedly connected to the outside of the storage box near the brush, and a baffle is fixedly connected to the top of the storage box. The wire brush and the brush are in close contact. When the cleaning roller rotates, the cleaning roller drives the brush to rotate. The brush passes through the wire brush during the movement, and the wire brush scrapes away the debris attached to the brush surface when the brush passes through.

[0010] The present invention also provides a method for using a silicone book box film applicator, comprising the following steps: Step 1: Place the phone inside the box and fix it in the preset position using positioning blocks and limiting blocks; Step 2: Rotate the moving block to place the storage plate above the phone screen. Tighten the threaded post to insert the limiting post into the limiting groove and lock the angle of the storage plate. Push the moving block to move the storage plate horizontally. At the same time, repeatedly squeeze the airbag to use negative pressure to suck in and expel the screen dust. The brush on the cleaning roller sweeps across the screen to remove larger particles. The wire brush automatically cleans the debris on the brush. Step 3: After cleaning, remove the storage board and place the positioning film over the protective film using the clips and blocks on the top of the box, ensuring that the protective film is aligned with the screen. Step 4: Rotate the cover so that the squeezing block can hold the soft pad on top of the protective film in the groove. At the same time, the soft pad and the top block together squeeze the top of the positioning film, squeezing the positioning film and the protective film together and fixing them in place. Step 5: Pull the pull strap to move the tape and film, causing the protective film to separate from the film and gradually adhere to the phone screen. After the film is applied, open the cover and remove the positioning film.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: In this silicone book-shaped screen protector applicator and its usage method, the positioning block and limiting block inside the box fix the phone's position. Combined with the squeezing block and top block locking the positioning film when the cover is closed, this prevents offset or shaking during application, thus improving the alignment accuracy between the screen protector and the screen. The layered structure of the pull strap, tape, film, and screen protector allows users to complete the main application process simply by rotating the cover and pulling the pull strap, reducing operational complexity. The dust extraction device uses an airbag, one-way valve, and rubber ring to create localized negative pressure above the screen, absorbing fine dust particles from the glass surface. The cleaning roller in the cleaning device drives a brush to sweep away larger debris, while a wire brush automatically scrapes off adhering substances and collects debris as the brush rotates, preventing secondary contamination. The positioning component can adjust the position of the storage plate, allowing it to be moved to the phone's surface during use and kept away from the phone when not in use, minimizing the impact on the application process. The cooperation of the limiting groove and limiting post restricts the angle of the storage plate, reducing the possibility of it detaching from the phone's surface under external force.

[0014] The technical solutions of this invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0015] Because these foreign objects, when pressed under the protective film, can form noticeable bubbles or white spots, they can easily cause problems that affect the display effect and the adhesion.

[0016] Therefore, in view of the above-mentioned problems, the present invention discloses a silicone book box film applicator and its method of use, see reference. Figure 1-3As shown, the device includes a box body 1 and a pull strap 3. A mobile phone 2 is housed inside the box body 1. The pull strap 3 is located directly above the mobile phone 2. Adhesive tape 4 is adhered to the top of the pull strap 3, a thin film 5 is adhered to the top of the adhesive tape 4, a protective film 6 is adhered to the top of the thin film 5, and a positioning film 7 is positioned directly above the protective film 6. A rotating cover 8 is rotatably connected to the outside of the box body 1. Soft pads 10 are provided at the bottom of the pull strap 3 and the top of the protective film 6. Two positioning blocks 11 are fixedly connected inside the box body 1 near the end of the mobile phone 2. Two limiting blocks 12 are fixedly connected to both sides of the part near the mobile phone 2. Two locking posts 13 are fixedly connected to the top of the box body 1. Two locking blocks 9 are fixedly connected to the top of the box body 1. The positioning film 7 is detachably connected to the inside of the two locking posts 13 and the outside of the two locking blocks 9, so that the positioning film 7 covers the protective film 6, thereby ensuring the alignment consistency between the protective film 6 and the screen. The inside of the flip cover 8 is fixedly connected to the pressing block 14 and the top block 15. The pressing block 14 has a groove inside that matches the soft pad 10. When the cover 8 is rotated and closed, the pressing block 14 houses the soft pad 10 on top of the protective film 6 in the groove. At the same time, the soft pad 10 and the top block 15 press together on the top of the positioning film 7, fixing the positioning film 7 to the top of the phone 2. This also prevents the positioning film 7 from shifting due to the pull strap 3. After being pressed, the soft pad 10 can evenly distribute the pressing force, avoiding direct contact between hard parts and the positioning film 7 or the protective film 6, which may cause indentations or damage. The layered structure of the pull strap 3, tape 4, film 5 and protective film 6 allows the user to simply rotate the cover 8 and pull the pull strap 3 to separate and apply the protective film 6. This simplifies the multiple steps of traditional screen protector application, such as alignment, peeling, and application, reducing the tediousness and complexity of screen protector application.

[0017] refer to Figure 4 and Figure 5 As shown, a dust collection device 16 for absorbing dust on the glass surface of the mobile phone 2 is provided on the top of the mobile phone 2. The dust collection device 16 includes a storage plate 161 located directly above the mobile phone 2. Three connecting pipes 162 are fixedly connected to the top of the storage plate 161. A suction tube 163 is fixedly connected to one end of the three connecting pipes 162 away from the storage plate 161. An air bag 164 is fixedly connected to one end of the suction tube 163. A one-way valve 165 is fixedly installed on the outside of both the suction tube 163 and the air bag 164. The exhaust direction of the two one-way valves 165 is the same, which is used to make the gas flow from the suction tube 163 to the air bag 164 and then to the outside. After the airbag 164 is squeezed, a local negative pressure is formed inside the storage plate 161, which draws the tiny dust particles on the screen into the storage plate 161. The dust particles enter the airbag 164 through the connecting tube 162 and the suction tube 163, and are then discharged through the one-way valve 165. This prevents dust from being pressed under the protective film 6 and forming air bubbles during the subsequent screen protector application process. Guide strips 166 are fixedly connected to both sides inside the storage plate 161 to guide the dust into the storage plate 161 and reduce the occurrence of dust falling out of the storage plate 161. A rubber ring 167 is fixedly connected to the bottom of the storage plate 161. The rubber ring 167 is located at the top of the phone 2. When the storage plate 161 is close to the screen, the rubber ring 167 forms a sealed contact with the glass surface, improving the efficiency of negative pressure dust suction and preventing the storage plate 161 from directly scratching the screen.

[0018] refer to Figure 6 and Figure 7 As shown, a positioning component 17 is provided on one side of the box body 1 and the storage plate 161. The positioning component 17 includes a limiting frame 171 fixedly connected to one side of the box body 1. A moving block 172 is movably connected to the outside of the limiting frame 171. One side of the moving block 172 is fixedly connected to one side of the storage plate 161. The storage plate 161 slides along the limiting frame 171 following the moving block 172, so that the storage plate 161 moves above the screen of the mobile phone 2, realizing the dust collection of the entire screen area. A threaded post 173 is threadedly connected inside the moving block 172. A limiting post 174 is fixedly connected to one side of the threaded post 173. A limiting post 174 is fixedly connected to the top of the limiting frame 171. The positioning bar 175 and the limiting post 174 are disposed inside the positioning bar 175. The limiting bar 175 has a limiting groove 176 inside. The limiting post 174 is inserted into the limiting bar 175 through the limiting groove 176. After the moving block 172 rotates to a suitable angle, the threaded post 173 is rotated into the moving block 172, so that the limiting post 174 is inserted into the limiting groove 176 of the limiting bar 175. The arrangement of the threaded post 173, the limiting post 174, the limiting bar 175 and the limiting groove 176 can limit the angle of the moving block 172, thereby preventing the moving block 172 from suddenly rotating at an angle during movement, causing the storage plate 161 to detach from the screen.

[0019] refer to Figure 8 and Figure 9As shown, the storage plate 161 is equipped with a cleaning device 18 for cleaning debris from the glass surface of the mobile phone 2. The cleaning device 18 includes two connecting blocks 181 fixedly connected to both sides of the storage plate 161. A cleaning roller 182 is rotatably connected inside the two connecting blocks 181. Multiple brushes 183 are fixedly connected to the outside of the cleaning roller 182. The brushes 183 are located directly above the mobile phone 2. When the cleaning roller 182 rotates, the brushes 183 sweep across the screen surface of the mobile phone 2, which can remove larger dust or fibers. A storage box 184 is fixedly connected to one side of the two connecting blocks 181. The outside of the storage box 184 is close to the brushes 183. A wire brush 185 is fixedly connected to one end of the 83, and a baffle 186 is fixedly connected to the top of the storage box 184. The wire brush 185 and the brush 183 are in close contact. When the cleaning roller 182 drives the brush 183 to rotate, the brush 183 passes through the wire brush 185 during the movement. The wire brush 185 scrapes off the debris attached to the surface of the brush 183, realizing the self-cleaning of the brush 183 and avoiding the situation where the brush 183 repeatedly cleans itself and causes secondary pollution to the screen due to its own dust. The storage box 184 is used to collect the debris scraped off by the wire brush 185, and the baffle 186 can prevent the debris from splashing outward when the brush 183 rotates.

[0020] This embodiment also discloses a method for using a silicone book box film applicator, including the following steps: Step 1: Place the mobile phone 2 inside the box 1 and fix the mobile phone 2 in the preset position by the positioning block 11 and the limiting block 12; Step 2: Rotate the moving block 172 to place the storage plate 161 above the screen of the mobile phone 2. Tighten the threaded post 173 so that the limiting post 174 is inserted into the limiting groove 176 to lock the angle of the storage plate 161. Push the moving block 172 to move the storage plate 161 laterally. At the same time, repeatedly squeeze the air bag 164 to use negative pressure to suck in and expel the screen dust. The brush 183 on the cleaning roller 182 sweeps across the screen to remove larger particles. The wire brush 185 automatically cleans the debris on the brush 183. Step 3: After cleaning, remove the storage plate 161 and place the positioning film 7 over the protective film 6 directly above it using the locking post 13 and locking block 9 at the top of the box body 1, ensuring that the protective film 6 is aligned with the screen. Step 4: Rotate the cover 8 so that the squeezing block 14 can hold the soft pad 10 on the top of the protective film 6 in the groove. At the same time, the soft pad 10 and the top block 15 together squeeze the top of the positioning film 7, squeezing the positioning film 7 and the protective film 6 together and fixing them. Step 5: Pull the pull strap 3 to move the tape 4 and film 5, so that the protective film 6 is separated from the film 5 and gradually adhered to the screen of the mobile phone 2. After the film is applied, open the cover 8 and remove the positioning film 7.

[0021] Working principle of the invention: During operation, the mobile phone 2 is placed inside the box 1, and the positioning block 11 and the limiting block 12 fix the mobile phone 2 in a preset position. Then, the moving block 172 is rotated to rotate on the surface of the limiting frame 171. The moving block 172 rotates the storage plate 161 to the surface of the mobile phone 2. Then, the threaded post 173 is tightened so that the limiting post 174 is inserted into the limiting groove 176 on the limiting strip 175, locking the angle of the moving block 172 to prevent the storage plate 161 from detaching from the screen. Then, the moving block 172 is pushed to move the storage plate 161 laterally, so that the storage plate 161 moves above the screen of the mobile phone 2.

[0022] When the storage plate 161 rotates, the rubber ring 167 at the bottom forms a seal with the screen of the phone 2. Then, the airbag 164 is repeatedly squeezed. Since the suction tube 163 and the two one-way valves 165 installed on the airbag 164 exhaust in the same direction, the gas flows from the storage plate 161 through the connecting tube 162 and the suction tube 163 to the airbag 164 and then is discharged to the outside. After squeezing the airbag 164, a local negative pressure is formed inside the storage plate 161. The floating dust on the screen surface is sucked into the storage plate 161, and then enters the airbag 164 through the connecting tube 162 and the suction tube 163, and is finally discharged through the one-way valve 165. The guide strips 166 on both sides inside the storage plate 161 guide the dust into the interior of the storage plate 161, reducing dust falling.

[0023] As the storage plate 161 moves laterally, the cleaning roller 182 rotates inside the connecting block 181. The brush 183 on the outside of the cleaning roller 182 sweeps across the screen of the phone 2, removing dust or fibers and other particles. During rotation, the brush 183 passes through the wire brush 185 fixed to the storage box 184. The wire brush 185 scrapes off the debris attached to the surface of the brush 183. The scraped debris falls into the storage box 184. The baffle 186 prevents debris from splashing. After the screen is cleaned, the threaded post 173 is unscrewed and the moving block 172 is rotated to move the storage plate 161 away from the phone 2.

[0024] Before applying the screen protector, the positioning film 7 is placed over the protective film 6 by the two locking posts 13 and two locking blocks 9 at the top of the box 1 to ensure the alignment of the protective film 6 with the screen of the mobile phone 2. Then, the cover 8 is rotated, and the squeezing block 14 inside the cover 8 stores the soft pad 10 on the top of the protective film 6 in the groove. At the same time, the soft pad 10 and the top block 15 together squeeze the top of the positioning film 7, pressing the positioning film 7 and the protective film 6 together.

[0025] When applying the screen protector, the pull strap 3 is pulled out. Since the top of the pull strap 3 is sequentially attached with tape 4, film 5 and protective film 6, the tape 4 and film 5 move together when the pull strap 3 is pulled out. This causes the protective film 6 to separate from the film 5 and gradually adhere to the screen of the mobile phone 2. After the protective film 6 is adhered, the user opens the flip cover 8, removes the positioning film 7, and completes the entire screen protector application operation.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.

The brush (183) on the cleaning roller (182) sweeps across the screen at the same time to remove larger particles. The wire brush (185) automatically cleans the debris on the brush (183). Step 3: After cleaning, remove the storage plate (161) and place the positioning film (7) over the protective film (6) directly above it using the clips (13) and clips (9) at the top of the box (1), ensuring that the protective film (6) is aligned with the screen. Step 4: Rotate the cover (8) so that the squeezing block (14) can hold the soft pad (10) on the top of the protective film (6) in the groove. At the same time, the soft pad (10) and the top block (15) together squeeze the top of the positioning film (7) to fix the positioning film (7) and the protective film (6) together. Step 5: Pull the pull strap (3) to move the tape (4) and film (5) so that the protective film (6) is separated from the film (5) and gradually attached to the screen of the mobile phone (2).
