Description

A dust removal film applicator with an elastic structure and a film application kit Technical Field

[0001] This application relates to the field of film applicator technology, and more specifically, to a dust removal film applicator with an elastic structure and a film applicator kit. Background Technology

[0002] To protect the screens of mobile phones, tablets, and other terminal devices, users typically apply a screen protector to the flat surface of the device (the one to be covered) to prevent scratches. During the application process, to achieve smooth lines and avoid air bubbles, thus maintaining the aesthetic appearance of the terminal device, a screen protector applicator is usually used to assist the user in precise positioning and application, thereby improving the application effect.

[0003] Existing screen protector applicators on the market use a pull-out design. The mobile device is first placed in the applicator with the screen facing upwards. The pull-out protective film is then attached to the casing, positioned above the screen. However, during the peeling process of the release liner, a gap is required between the protective film and the screen. Because of this gap, when pressing the film down to adhere it to the screen, the lack of elasticity in the casing makes the film prone to bending or damage under pressure, leading to application failure.

[0004] Therefore, existing technologies still need to be improved and developed.

[0005] Utility Model Content

[0006] The purpose of this application is to provide a dust removal film applicator and film application kit with an elastic structure, which solves the problem that the protective film layer in the prior art is easily bent or damaged by pressure during the extrusion process.

[0007] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0008] On the one hand, this application provides a dust removal film applicator with an elastic structure for applying protective film to a mobile terminal. The dust removal film applicator includes a housing with an inner cavity for accommodating the mobile terminal.

The elastic structure is located on the outside of the accommodating cavity, and a second limiting member is provided on the elastic structure.

[0010] The first and second limiting members are used to connect the protective film, respectively.

[0011] The protective film is positioned at a predetermined distance from the screen of the mobile terminal by the elastic expansion of the elastic structure, or by the force applied to the elastic structure to bring the protective film into contact with the screen of the mobile terminal.

[0012] Optionally, the elastic structure includes a bending portion, one end of which is connected to the second end of the housing;

[0013] The support platform is connected to the end of the bent part away from the shell, and the second limiting member is set on the support platform;

[0014] The support platform moves relative to the shell through the bending of the bending section.

[0015] Optionally, the bending portion includes a bending plate connected to the second end of the housing and forming a U-shaped groove, the opening of which faces the open side of the accommodating cavity;

[0016] The width of the opening of the U-shaped groove is greater than the width of the bottom of the U-shaped groove.

[0017] Optionally, a top platform is provided at the first end of the housing, and a first limiting member is provided on the top platform;

[0018] The upper surface of the top platform is flush with the upper surface of the support platform and is higher than the upper surface of the shell.

[0019] A tear-opening is formed between the top platform and the shell.

[0020] Optionally, the top platform includes a top plate that extends along the width direction, and the two sides of the top plate in the width direction are respectively connected to the housing;

[0021] or,

[0022] The top platform includes a left support plate and a right support plate, which are respectively connected to the two sides of the shell in the width direction.

[0023] Optionally, the first limiting member includes: at least two first hooks, the two first hooks being spaced apart along the width direction of the top platform, and the two first hooks being used to connect to the first end positioning hole of the positioning release layer of the protective film;

[0024] The second limiting member includes at least two second hooks, which are spaced apart along the width direction of the elastic structure. The two second hooks are respectively used to connect to the second end positioning holes of the positioning release layer of the protective film.

[0025] Optionally, the dust removal film applicator also includes an extrusion component, which is movably mounted on the housing;

[0026] The protective film connected to the first and second limiting members is squeezed by pushing the squeezing member;

[0027] The height between the extrusion and the upper surface of the housing is adjustable or fixed.

[0028] Optionally, a guide rail is provided on the side of the housing in the width direction;

[0029] The extrusion component includes: a sliding frame, which is detachably connected to the housing and slides along the length direction on a guide rail;

[0030] The extrusion section is connected to the sliding frame.

[0031] Optionally, the extrusion section includes a roller, which is rotatably connected to the sliding frame;

[0032] Alternatively, the extrusion section includes an extrusion block, which is fixedly connected to the sliding frame.

[0033] On the other hand, this application also proposes a film application kit, including a dust removal film applicator with an elastic structure as described above and a protective film;

[0034] The protective film includes: an adhesive layer, a positioning release layer, and a peel-off release layer; the positioning release layer is connected to the first limiting member and the second limiting member.

[0035] The beneficial effects of the dust removal film applicator and film application kit with an elastic structure provided in this application are at least as follows: By setting a first limiting member at the first end of the shell along its length direction, and integrally forming an elastic structure at the second end of the shell along its length direction, the elastic structure is located on the outside of the accommodating cavity, and the protective film is connected to the first limiting member through a second limiting member on the elastic structure. Before the film application begins, the elastic structure expands to create a predetermined distance between the protective film and the screen of the mobile terminal, thus allowing the release liner of the protective film to detach within this gap during the pulling process, and facilitating dust removal of the mobile terminal screen within this gap during the pulling process. After the release liner is pulled out, the film layer is aligned with the screen of the mobile terminal. By squeezing the protective film, the elastic structure is compressed, allowing the protective film to deform downwards, thus enabling the film layer to smoothly move down and contact the screen of the mobile terminal. The film layer will not be subjected to excessive compression deformation during the downward movement, resulting in damage, making the film application process smoother. Attached Figure Description

[0046] Example 1

[0047] As shown in Figures 2 and 3, this embodiment proposes a dust-removing film applicator with an elastic structure for applying a film to the screen of a mobile terminal. The mobile terminal in this embodiment can be various electronic products, such as a mobile phone 10, a tablet computer, an e-reader, a smartwatch, or other electronic devices. For ease of structural description, a mobile phone 10 is used as an example. The long side of the mobile phone 10 is the length direction (front-to-back direction), the short side is the width direction (left-to-right direction), and the thickness direction is the vertical direction. The length direction, width direction, and vertical direction mentioned below are all based on this. This embodiment's dust-removing film applicator with an elastic structure is used to adhere the film portion of the protective film 20 to the screen of the mobile phone 10. As shown in Figures 2 and 3, the protective film 20 can take various forms, for example, one form mainly includes: an adhesive layer 23, a positioning release layer 21, and a peel-off release layer 24. The film layer 23 (the actual film to be applied to the screen surface) is attached to the surface of the mobile phone 10 to protect the screen. The positioning release layer 21 is detachably disposed on one side of the film layer 23 and is used to connect to the flexible dust-removing film applicator. The peel-off release layer 24 is disposed on the side of the film layer 23 facing away from the positioning release layer 21 and towards the mobile phone 10. During use, both the positioning release layer 21 and the peel-off release layer 24 are pulled away from the film layer 23, leaving only the film layer 23 adhered to the screen surface of the mobile phone 10.

[0048] As shown in Figures 1, 2, and 3, the dust removal film applicator with elastic structure 200 in this embodiment mainly includes a housing 100, elastic structure 200, first limiting member 300, and second limiting member 400. The housing 100 can be configured as a square structure, and the housing 100 is laid flat during use. An accommodating cavity 110 is provided inside the housing 100. Specifically, the bottom of the housing 100 is a base plate, and baffles are provided around the base plate to form the accommodating cavity 110. The accommodating cavity 110 is open upwards to form an open side. The accommodating cavity 110 is used to accommodate and limit the mobile phone 10 to be applied film. The first limiting member 300 is provided at the first end in the length direction of the housing 100, and the elastic structure 200 is integrally formed at the second end in the length direction of the housing 100. The first end can be the rear end, and the second end can be the front end. The elastic structure 200 is located on the outside of the accommodating cavity 110. A second limiting member 400 is provided on the elastic structure 200. The first limiting member 300 and the second limiting member 400 are respectively used to connect the protective film 20. Specifically, the first limiting member 300 and the second limiting member 400 are respectively connected to the positioning release layer 21 of the protective film 20 at the rear end and the front end, so that the protective film 20 is limited and connected to the housing 100, and the protective film 20 faces upward, while the mobile phone 10 is located below the protective film 20. The elastic structure 200 extends elastically, maintaining a predetermined distance between the protective film 20 and the screen of the mobile phone 10. Specifically, when the two ends of the positioning release layer 21 of the protective film 20 are connected to the first limiting member 300 and the second limiting member 400, the elastic structure 200 opens, tauting the protective film 20. This creates a dust removal space 22 between the protective film 20 and the screen of the mobile phone 10, facilitating dust removal of the screen during the pull-out process of the release layer. During film application, squeezing the protective film 20 causes the elastic structure 200 to contract, resulting in a downward movement of the film layer 23 on the protective film 20, bringing the film layer 23 into contact with the screen of the mobile phone 10.

[0049] In this embodiment, the screen protector applicator has a first limiting member 300 at the first end of the housing 100 along its length, and an elastic structure 200 integrally formed at the second end of the housing 100 along its length. The elastic structure 200 is located outside the accommodating cavity 110, and the protective film 20 is connected to the first limiting member 300 via a second limiting member 400 on the elastic structure 200. Before the application begins, the elastic structure 200 expands elastically to create a predetermined distance between the protective film 20 and the screen of the mobile phone 10. This allows the release liner 24 of the protective film 20 to have space to detach during the pulling process, and facilitates dust removal from the screen of the mobile phone 10 within this gap. When the release layer 24 is pulled out, the film layer 23 is aligned with the screen of the mobile phone 10. By squeezing the protective film 20, the elastic structure 200 is compressed, giving the protective film 20 room to deform downwards. This allows the film layer 23 of the protective film 20 to move smoothly down and contact the screen of the mobile phone 10. The film layer 23 will not be damaged by excessive squeezing and deformation during the downward movement, making the film application process smoother.

[0050] As shown in Figures 1, 2, and 3, the elastic structure 200 further includes a bending portion 210 and a support platform 220. One end of the bending portion 210 is connected to the second end of the housing 100, and the support platform 220 is connected to the end of the bending portion 210 away from the housing 100. A second limiting member 400 is disposed on the support platform 220, which moves relative to the housing 100 due to the bending of the bending portion 210. When the second limiting member 400 and the first limiting member 300 are connected to the protective film 20, the bending portion 210 is compressed by squeezing the protective film 20, causing the support platform 220 to move towards the second end of the housing 100. This reduces the distance between the first limiting member 300 and the second limiting member 400 in the length direction, thus allowing the protective film 20 to have downward movement allowance. The bending portion 210 can adopt various structures, such as a complete bent elastic plate in the width direction or multiple bent elastic plates spaced apart in the width direction, etc.

[0051] As shown in Figures 1, 2, and 3, in this embodiment, the bending portion 210 further includes a bending plate 211. The bending plate 211 is connected to the second end of the housing 100 and forms a U-shaped groove 212. The opening of the U-shaped groove 212 faces the open side of the accommodating cavity 110. By using U-shaped bending plates 211 for connection, a stable elastic force can be generated. The width between the U-shaped grooves 212 (the distance between the inner walls in the length direction) provides a moving position for the support platform 220, enabling the support platform 220 to have stable moving and resetting functions. In this embodiment, the width of the opening of the U-shaped groove 212 is greater than the width of the bottom of the U-shaped groove 212, and the width of the opening at the top of the U-shaped groove 212 is greater than the width of the bottom of the groove at the bottom, thereby allowing the upper end of the bending portion 210 to undergo greater deformation, thereby increasing the moving distance of the support platform 220 and improving the elastic performance of the bending plate 211.

[0052] It is easy to imagine that the bending plate 211 is a continuous structure in the width direction, or it can be a multiple spaced arrangement, or a small section of the bending plate 211 can be set only in the middle of the width direction of the housing 100, all of which can achieve the technical effect.

[0053] As shown in Figures 1, 2, and 3, in this embodiment, the first end of the housing 100 is provided with a top platform 120, and the first limiting member 300 is provided on the top platform 120; the top platform 120 is provided at the rear end of the housing 100, and the upper surface of the top platform 120 is flush with the upper surface of the support platform 220 and is higher than the upper surface of the housing 100. Thus, when the first limiting member 300 and the second limiting member 400 are connected to the protective film 20, the protective film 20 can be supported in the height direction to form a dust removal space 22.

[0054] A tear-off opening 130 is formed between the top platform 120 and the housing 100. The tear-off opening 130 is used to pull out the tear-off release layer 24 of the protective film 20. The tear-off release layer 24 of the protective film 20 passes through the tear-off opening 130, making it convenient for the user to pull out the tear-off release layer 24 from the tear-off opening 130.

[0055] As shown in Figure 1, the top platform 120 in this embodiment can further adopt two structures, as detailed below:

[0056] As shown in Figures 1, 2, and 3, the first type of top platform 120 structure includes a top plate 121, which extends along the width direction. Both sides of the top plate 121 in the width direction are connected to the housing 100. The top plate 121 is a single piece of plate structure in the width direction. Both ends of the top plate 121 are connected and supported to the housing 100, allowing the top plate 121 to be suspended above the upper surface of the housing 100, providing a stable support structure for the first limiting member 300.

[0057] As shown in Figure 6, the second type of top platform 120 structure includes a left support plate 122 and a right support plate 123, which are respectively connected to both sides of the housing 100 in the width direction. The left support plate 122 extends to the right by a short length, and the right support plate 123 extends to the left by a short length. The left support plate 122 and the right support plate 123 are not connected, but they can still provide support for the first limiting member 300, and save materials and facilitate production.

[0058] As shown in Figures 1, 2, and 3, the first limiting member 300 of this embodiment further includes at least two first hooks 310, which are spaced apart along the width direction of the top platform 120. Each of the two first hooks 310 is used to connect to the first end positioning hole of the positioning release layer 21 of the protective film 20. The second limiting member 400 specifically includes at least two second hooks 410, which are spaced apart along the width direction of the elastic structure 200. Each of the two second hooks 410 is used to connect to the second end positioning hole of the positioning release layer 21 of the protective film 20. The first hooks 310 are located at the rear end, and the second hooks 410 are located at the front end. After the positioning release layer 21 of the protective film 20 is connected to the first hook 310, the two first hooks 310 in the width direction and the two second hooks 410 in the width direction at the other end are used to connect the two ends of the protective film 20 in the length direction, so that the protective film 20 is positioned above the support limiting part, and the entire protective film 20 can be positioned above the screen of the mobile phone 10. The peelable film layer 23 extends out from the tear opening 130 at the rear end, making it convenient for the user to hold. During the process of peeling the release layer 24 of the protective film 20 from the film layer 23, the release layer 24 will come into contact with the screen of the mobile phone 10 during the tearing process, thereby cleaning the screen of the mobile phone 10. After being detached, the release layer 24 is removed from the tear opening 130, exposing the film layer 23 on the protective film 20 and aligning it with the screen of the mobile phone 10 below.

[0059] As shown in Figures 4 and 5, the dust removal film applicator of this embodiment further includes an extrusion member 500, which is movably disposed on the housing 100. The extrusion member 500 is pushed to extrude the protective film 20 connected to the first limiting member 300 and the second limiting member 400. The extrusion member 500 can be a scraper or a roller. Extruding the protective film 20 with the extrusion member 500 stabilizes the force during the film application process. For example, extruding from front to back with the extrusion member 500 can effectively prevent air bubbles from forming.

[0060] As shown in Figures 4 and 5, in this embodiment, a guide rail 140 is further provided on the side of the housing 100 in the width direction, allowing the extruder 500 to move from front to back along the guide rail 140. The extruder 500 specifically includes a sliding frame 510 and an extrusion part 520. The sliding frame 510 is detachably connected to the housing 100 and slides along the length direction on the guide rail 140, while the extrusion part 520 is connected to the sliding frame 510. Through the cooperation of the guide rail 140 and the sliding frame 510, stable movement in the length direction is achieved, ensuring stable force during the extrusion process.

[0061] Furthermore, the extrusion section 520 in this embodiment can take several forms:

[0062] As shown in Figure 4, in the first form, the extrusion section 520 includes a roller 521, which is rotatably connected to the sliding frame 510. The roller 521 forms the rolling action through rotation. The roller 521 can be a rubber roller, foam roller, etc., making it suitable for both soft and hard films. Furthermore, the roller 521 can also have a curved profile, allowing for the extrusion of curved screens.

[0063] As shown in Figure 5, in the second form, the extrusion part 520 includes an extrusion block 522, which is fixedly connected to the sliding frame 510. The extrusion block 522 pushes the surface, creating a sliding motion. The extrusion block 522 can be a rubber strip, foam strip, etc., making it suitable for both soft and hard films. Furthermore, the extrusion block 522 can also have a curved profile, allowing for the extrusion of curved screens.

[0064] It should be noted that the height between the extrusion component 500 and the upper surface of the housing 100 is adjustable or fixed. When the height of the extrusion component 500 is adjustable, for example by replacing the rollers 521 with different diameters or the extrusion blocks 522 with different heights, the height of the extrusion component 500 can be adjusted to suit mobile phones of different thicknesses. Alternatively, different height mating positions can be set on the sliding frame 510, and the height of the extrusion component 500 can be adjusted by mating with the guide rail 140 at different heights.

[0065] Example 2

[0066] As shown in Figures 1, 2, and 3, this embodiment proposes a screen protector kit, including a dust removal applicator with an elastic structure 200 as described above, and a protective film 20. As shown in Figure 3, the protective film 20 includes an adhesive layer 23, a positioning release layer 21, and a peel-off release layer 24. The positioning release layer 21 is connected to the first limiting member 300 and the second limiting member 400. The peel-off release layer 24 is pulled out from the peel-off opening 130 to align the adhesive layer 23 with the screen of the mobile phone 10. The adhesive layer 23 is used to adhere to the surface of the mobile phone 10, thereby protecting the screen of the mobile phone 10.

[0067] The positioning release layer 21 is detachably disposed on one side of the film layer 23. A first positioning hole 21a is provided at the rear end along the length of the positioning release layer 21, and a second positioning hole 21b is provided at the front end. The first positioning hole 21a and the second positioning hole 21b are respectively fitted onto the first hook 310 and the second hook 410 for positioning. The peelable release layer 24 is disposed on the side of the film layer 23 opposite to the positioning release layer 21 and facing the mobile phone 10.

[0068] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
