Description

Technical Field

[0001] The present application relates to the technical field of film applicators, and more specifically, to a dust removal film applicator and a film applicator kit with an elastic structure. Background Art

[0002] In order to protect the screens of mobile phones, tablets and other terminal devices, users usually apply a layer of film on the flat surface of the terminal device (the device to be filmed) to prevent the touch screen from being scratched. During the film application process, in order to pursue smooth lines and avoid bubbles, so that the appearance of the terminal device remains beautiful, a film applicator is usually used to assist the user in precise positioning and film application, so that the film application effect can be improved.

[0003] Currently available on the market are film applicators that use pull-out protective films. First, place the mobile terminal into the applicator with the screen facing upward. The pull-out protective film is then attached to the housing, positioned above the screen. However, due to the tearing process of the release layer, a certain gap between the protective film and the screen is required. This gap can easily cause the protective film to bend or be damaged during the pressing process to adhere to the screen surface. Due to the lack of elasticity in the housing, the film layer can be easily bent or damaged during the pressing process, leading to film application failure.

[0004] Therefore, the existing technology still needs to be improved and developed. Utility Model Content

After the tear-off layer is pulled out, the film layer is aligned with the mobile terminal screen, and the elastic structure is compressed by the protective film, causing it to contract under force, thereby allowing the protective film to deform downwardly. This allows the protective film layer to smoothly move downward and contact the mobile terminal screen. The film layer is not significantly squeezed and deformed during the downward movement, resulting in damage, thereby facilitating the film application process. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] Example 1

[0047] like Figure 2 、 Figure 3 As shown, this embodiment proposes a dust removal film applicator with an elastic structure, which is used to apply a film to the screen of a mobile terminal to be applied with a film. The mobile terminal in this embodiment can be various electronic products, such as mobile phones 10, tablet computers, e-books, smart watches and other electronic devices. To facilitate the structural description of this embodiment, the mobile phone 10 is taken as an example for explanation. The long side direction of the mobile phone 10 is the length direction (front and back direction), the short side direction is the width direction (left and right direction), and the thickness direction is the up and down direction. The length direction, width direction and up and down direction hereinafter are all based on this as a reference for structural description. The dust removal film applicator with an elastic structure in this embodiment is used to adhere the membrane part in the protective film 20 to the screen of the mobile phone 10, as shown in FIG. Figure 2 、 Figure 3 As shown, the protective film 20 can take a variety of forms. For example, one form mainly includes: a film layer 23, a positioning release layer 21, and a tear-off release layer 24. The film layer 23 (the film that is actually attached to the screen surface) is used to be attached to the surface of the mobile phone 10, thereby protecting the screen of the mobile phone 10; the positioning release layer 21 is detachably arranged on one side of the film layer 23, and the positioning release layer 21 is used to be connected to the dust removal film applicator with an elastic structure. The tear-off release layer 24 is arranged on the side of the film layer 23 away from the positioning release layer 21 and facing the mobile phone 10. During use, the positioning release layer 21 and the tear-off release layer 24 are both pulled away from the film layer 23, leaving only the film layer 23 adhered to the screen surface of the mobile phone 10.

[0048] like Figure 1 、 Figure 2 、 Figure 3As shown, the dust removal film applicator with an elastic structure 200 of this embodiment mainly includes a shell 100, an elastic structure 200, a first limiting member 300 and a second limiting member 400. The shell 100 can be set as a square structure, and the shell 100 is placed flat when in use. An accommodating inner cavity 110 is provided in the shell 100. In the specific structure, the bottom of the shell 100 is a base plate, and retaining edges are provided around the base plate to enclose the accommodating inner cavity 110. The accommodating inner cavity 110 is open upward to form an open side. The accommodating inner cavity 110 is used to accommodate and limit the mobile phone 10 to be filmed. The first end of the shell 100 in the longitudinal direction is provided with a first limiting member 300, and the second end of the shell 100 in the longitudinal direction is integrally formed with an elastic structure 200. 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, and 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 limitedly connected to the shell 100, and the protective film 20 is facing upward, and the mobile phone 10 is located below the protective film 20. The elastic structure 200 stretches to maintain 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 and second stoppers 300 and 400, the elastic structure 200 expands, tightening the protective film 20. This creates a dust removal space 22 between the protective film 20 and the screen of the mobile phone 10, allowing the release layer to remove dust from the screen of the mobile phone 10 within this dust removal space 22 during the removal process. During film application, the protective film 20 is squeezed, causing the elastic structure 200 to contract, causing the film layer 23 on the protective film 20 to move downward, thereby bringing the film layer 23 into contact with the screen of the mobile phone 10.

[0049] The screen film applicator of this embodiment features a first stopper 300 disposed at the first longitudinal end of the housing 100. An elastic structure 200 is integrally formed at the second longitudinal end of the housing 100, positioning the elastic structure 200 outside the accommodating cavity 110. The protective film 20 is connected to the first stopper 300 via a second stopper 400 on the elastic structure 200. Before the screen film application begins, the elastic structure 200 stretches to create a predetermined distance between the protective film 20 and the screen of the mobile phone 10. This allows the release layer 24 of the protective film 20 to fall out of the gap during the removal process, facilitating dust removal from the screen of the mobile phone 10 within the gap. After 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 forced to shrink, so that the protective film 20 has room to deform downward, so that the film layer 23 of the protective film 20 can move down smoothly and contact the screen of the mobile phone 10. The film layer 23 will not be greatly squeezed and deformed during the downward movement, resulting in damage, making the film application process smoother.

[0050] like Figure 1 、 Figure 2 、 Figure 3 As shown, further, the elastic structure 200 specifically includes a bending portion 210 and a supporting platform 220. One end of the bending portion 210 is connected to the second end of the housing 100, and the supporting platform 220 is connected to the end of the bending portion 210 facing away from the housing 100. The second limiting member 400 is disposed on the supporting platform 220, and the supporting platform 220 moves relative to the housing 100 through 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, and the supporting platform 220 moves toward 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 longitudinal direction, thereby allowing the protective film 20 to move downward. The bending portion 210 can adopt a variety of structures, such as a completely bent elastic plate in the width direction or multiple bent elastic plates arranged at intervals in the width direction.

[0051] like Figure 1 、 Figure 2 、 Figure 3As shown, further, the bending portion 210 of this embodiment includes a bending plate 211, which is connected to the second end of the shell 100 and forms a U-shaped groove 212, and the opening of the U-shaped groove 212 faces the open side of the accommodating inner cavity 110. By adopting the U-shaped bending plate 211 for connection, a stable elastic force can be generated, and the width between the U-shaped grooves 212 (the inner wall spacing in the length direction) provides a moving position for the movement of the supporting platform 220, so that the supporting platform 220 has stable movement and reset functions. The width of the opening of the U-shaped groove 212 of this embodiment is greater than the width of the groove bottom of the U-shaped groove 212, and the opening width above the U-shaped groove 212 is greater than the groove bottom width below, so that the upper end of the bending portion 210 can produce a larger deformation, thereby increasing the moving distance of the supporting platform 220 and making the elastic performance of the bending plate 211 better.

[0052] It is easy to imagine that the bending plate 211 is a continuous structure in the width direction, or it can be a plurality of spaced-apart structures or only a small section of the bending plate 211 is set in the middle position in the width direction of the shell 100, and the technical effect can be achieved.

[0053] like Figure 1 、 Figure 2 、 Figure 3 As shown, further, a top platform 120 is provided at the first end of the shell 100 of this embodiment, and a first limiting member 300 is provided on the top platform 120; a top platform 120 is provided at the rear end of the shell 100, and the upper surface of the top platform 120 is flush with the upper surface of the supporting platform 220 and both are higher than the upper surface of the shell 100, so that 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 propped up in the height direction to form a dust removal space 22.

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

[0055] like Figure 1 As shown, further, the top platform 120 of this embodiment can adopt two structures, as follows:

[0056] like Figure 1 、 Figure 2 、 Figure 3As shown, the first top platform 120 structure includes a top plate 121, which extends in 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 provided as a single plate structure in the width direction. The two ends of the top plate 121 are connected to the housing 100 for support, so that the top plate 121 is suspended above the upper surface of the housing 100, providing a stable support structure for the first limiter 300.

[0057] like Figure 6 As shown, the second 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 width direction of the shell 100. The left support plate 122 extends a short distance toward the right, and the right support plate 123 extends a short distance toward the left. The left support plate 122 and the right support plate 123 are not connected, which can also provide support for the first limit member 300, save materials, and facilitate production.

[0058] like Figure 1 、 Figure 2 、 Figure 3 As shown, the first retaining member 300 of this embodiment further includes: at least two first hooks 310, the two first hooks 310 are spaced apart along the width direction of the top platform 120, and the two first hooks 310 are respectively used to connect to the first end positioning holes of the positioning release layer 21 of the protective film 20. The second retaining member 400 specifically includes: at least two second hooks 410, the two second hooks 410 are spaced apart along the width direction of the elastic structure 200, and the two second hooks 410 are respectively used to connect to the second end positioning holes 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 limit portion. This allows the entire protective film 20 to be positioned above the screen of the mobile phone 10. The tear-off film layer 23 extends through the tear-off opening 130 at the rear end, making it easier for the user to hold it. During the process of tearing the tear-off layer 24 of the protective film 20 from the film layer 23, the tear-off layer 24 will contact the screen of the mobile phone 10 during the tearing process, thereby removing dust from the screen of the mobile phone 10. The detached tear-off layer 24 moves out of the tear-off 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] like Figure 4 、 Figure 5As shown, 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 squeeze the protective film 20 connected to the first stopper 300 and the second stopper 400. The extrusion member 500 can be a scraper or a roller. By squeezing the protective film 20 with the extrusion member 500, the force applied during the film application process is stabilized. For example, by squeezing from front to back with the extrusion member 500, the generation of bubbles can be effectively avoided.

[0060] like Figure 4 、 Figure 5 As shown, in this embodiment, guide rails 140 are provided on the widthwise side surfaces of the housing 100, and the extrusion member 500 can move from front to back along the guide rails 140. The extrusion member 500 specifically comprises a sliding frame 510 and an extrusion portion 520. The sliding frame 510 is detachably connected to the housing 100 and slides longitudinally on the guide rails 140. The extrusion portion 520 is connected to the sliding frame 510. The cooperation between the guide rails 140 and the sliding frame 510 allows for stable longitudinal movement, ensuring a stable force during the extrusion process.

[0061] Furthermore, the extrusion portion 520 of this embodiment can be in multiple forms:

[0062] like Figure 4 As shown, in the first embodiment, the extrusion unit 520 includes a rolling roller 521, which is rotatably connected to the sliding frame 510. The rotation of the rolling roller 521 creates a rolling process. The rolling roller 521 can be a rubber roller, a foam roller, or the like, making it suitable for both soft and hard films. Furthermore, the rolling roller 521 can have a curved profile, allowing for extrusion of curved screens.

[0063] like Figure 5 As shown, in the second embodiment, the extrusion unit 520 includes an extrusion block 522 fixedly connected to the sliding frame 510. This allows for displacement by the extrusion block 522. The extrusion block 522 can be a rubber strip, a foam strip, or the like, making it suitable for both soft and hard films. Furthermore, the extrusion block 522 can have a curved profile, allowing for extrusion of curved screens.

[0064] It should be noted that the height between the extrusion member 500 and the upper surface of the housing 100 can be adjustable or fixed. When the height of the extrusion member 500 is adjustable, for example, by replacing the roller 521 with different diameters or the extrusion block 522 with different heights, the height of the extrusion member 500 can be adjusted to accommodate mobile phones of varying thicknesses. Alternatively, the height of the extrusion member 500 can be adjusted by providing engagement points of varying heights on the sliding frame 510, which engage with the guide rail 140 at each engagement point.

[0065] Example 2

[0066] like Figure 1 、 Figure 2 、 Figure 3 As shown, this embodiment provides a film sticking kit, including the dust removal film sticking device with elastic structure 200 and protective film 20 as described above. Figure 3 As shown, the protective film 20 includes a film layer 23, a positioning release layer 21, and a tear-off release layer 24. The positioning release layer 21 is connected to the first stopper 300 and the second stopper 400. The tear-off release layer 24 is pulled out through the tear opening 130 to align the film layer 23 with the screen of the mobile phone 10. The film layer 23 is attached to the surface of the mobile phone 10 to protect the screen.

[0067] The release layer 21 is detachably attached to one side of the film layer 23. A first positioning hole 21a is provided at the rear end of the release layer 21, and a second positioning hole 21b is provided at the front end. The first and second positioning holes 21a and 21b respectively fit over the first and second hooks 310 and 410 for positioning. A tear-off release layer 24 is attached to the side of the film layer 23 facing away from the release layer 21 and toward the phone 10.

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