Technical Field

[0001] The present application relates to the technical field of film applicators, and more specifically, to a foam-adaptable dust removal film applicator and a film applicator kit. Background Art

[0002] In order to protect the screen of a watch, for example, a smartwatch screen needs to be frequently touched, and a film is usually applied to the surface of the watch screen to prevent the touch screen from being scratched. During the film application process, in order to achieve 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. There are some film applicators on the market that use pull-out protective films to apply films to watches. During the film application process, in order to adapt to more models of mobile phones, detachable limit blocks are usually equipped to match the mobile phone to be applied. The limit blocks have different specifications, so different limit blocks can be selected according to the specifications of the mobile phone and installed in the film applicator, so that multiple models of mobile phones can be applied, improving the versatility of the film applicator.

[0003] However, the existing market generally uses hard limit blocks, which are non-deformable and not only easily scratch the mobile phone during the positioning process, but also have high injection molding costs, resulting in increased production costs of the film applicator.

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

[0005] The purpose of the present application is to provide a foam-adaptable dust removal film applicator and a film applicator kit, which solves the problem in the prior art that hard limit blocks are prone to scratching mobile terminals during use and have high production costs.

[0006] To achieve the above objectives, the technical solution adopted in this application is:

[0040] Example 1

[0041] like Figure 1 、 Figure 3As shown, this embodiment proposes a foam-adaptive dust-removing film applicator for applying a film to the screen of a mobile terminal. The mobile terminal in this embodiment can be a mobile phone 10, a tablet computer, an e-reader, a smart watch, or other electronic devices with a screen. To facilitate the structural description of this embodiment, the structure is described by taking the mobile phone 10 as an example. The mobile phone 10 is usually square. To facilitate the structural description, this embodiment takes the direction of the top and bottom of the mobile phone as the length direction, the left and right directions as the width direction, and the thickness direction as the up and down direction. The length direction, width direction, and up and down directions of each component hereinafter are all described based on this. According to actual needs, the length direction and the width direction can be swapped, and the effect of this solution can also be achieved.

[0042] like Figure 3 、 Figure 4 、 Figure 5 As shown, the foam-adaptive dust removal film applicator of this embodiment is used to adhere the film portion of the protective film 20 to the screen of the mobile phone 10, as shown in FIG. Figure 4 、 Figure 5 、 Figure 7 As shown, the protective film 20 can take a variety of forms. For example, one form mainly includes: a film layer 22, a positioning release layer 21, and a tear-off release layer 23. The film layer 22 (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 22, and the positioning release layer 21 is used to be connected to the present foam-adaptive dust removal film applicator. The tear-off release layer 23 is arranged on the side of the film layer 22 away from the positioning release layer 21 and facing the mobile phone 10. When in use, the positioning release layer 21 and the tear-off release layer 23 are both pulled away from the film layer 22, and only the film layer 22 is adhered to the screen surface of the mobile phone 10.

[0043] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 5As shown, the foam adaptive dust removal film applicator of this embodiment mainly includes a shell 100, a plurality of elastic limiting blocks 200, a first limiting member 300 and a second limiting member 400. The shell 100 can be set to a square structure, and the shell 100 is placed flat when in use. A accommodating inner cavity 111 is provided in the shell 100, and the accommodating inner cavity 111 is open upward to form an open side. The accommodating inner cavity 111 is used to accommodate a plurality of elastic limiting blocks 200. The plurality of elastic limiting blocks 200 are fixedly arranged or detachably arranged in the length direction or / and width direction of the accommodating inner cavity 111. The inner walls of the plurality of elastic limiting blocks 200 form a positioning cavity 210. The positioning cavity 210 is used to accommodate a mobile terminal. The elastic limiting blocks 200 can be arranged against the inner wall of the accommodating inner cavity 111, so that the side inner wall of the elastic limiting block 200 abuts against the side wall of the mobile phone 10 to achieve the limitation of the mobile phone 10. Therefore, it is necessary to select an elastic limit block 200 that matches the mobile phone 10 to be filmed. Accordingly, the elastic limit block 200 is also provided in sets according to different models of mobile phones 10, which is convenient for users to use. A first limit member 300 and a second limit member 400 are respectively provided at both ends of the length direction of the shell 100. For example, the first limit member 300 can be at the first end, wherein the first end can be the rear end, and the second limit member 400 can be at the second end, wherein the second end can be the front end. The first limit member 300 and the second limit member 400 are respectively used to connect the protective film 20. Specifically, the first limit member 300 and the second limit member 400 are connected to the positioning release layer 21 of the protective film 20 at the rear end and the front end respectively, so that the protective film 20 is limitedly connected to the shell 100, and the protective film 20 is above, and the mobile phone 10 is located below the protective film 20. Since the protective film 20 is spaced apart from the screen of the mobile phone 10 , a dust removal space is provided between the protective film 20 and the screen of the mobile phone 10 , which facilitates the tearing off of the release layer 23 to remove dust from the screen of the mobile phone 10 in the dust removal space during the pulling out process, thereby achieving a dust removal effect.

[0044] The foam-adaptive dust removal film applicator of this embodiment can select a plurality of elastic limit blocks 200 that are suitable for different mobile phones 10, and install the plurality of elastic limit blocks 200 in the length direction and / or width direction of the accommodating inner cavity 111, thereby forming a positioning cavity 210 by the inner walls of the plurality of elastic limit blocks 200, and placing the mobile terminal in the positioning cavity 210 for positioning. Since the elastic limit blocks 200 are used, which are flexible inner walls, the flexible inner walls are used to abut against the mobile terminal to effectively avoid the problem of scratches on the side walls of the mobile terminal. By connecting the protective film 20 to the first limit member 300 and the second limit member 400, the protective film 20 is positioned on one side of the screen of the mobile terminal and spaced apart from the screen, thereby achieving relative positioning of the protective film 20 and the screen of the mobile terminal and ensuring the correct position of the film. Not only can multiple mobile phones 10 use the same housing 100 for film application, effectively reducing design costs, but the material cost of the elastic limit block 200 is relatively low compared to the hard limit block, reducing the production cost of the dust removal film applicator.

[0045] like Figure 1 、 Figure 2 As shown, further, in this embodiment, a bonding position 120 is provided at the bottom of the accommodating inner cavity 111, and the elastic limiting block 200 is bonded to the bonding position 120. The elastic limiting block 200 is fixed to the bonding position 120 by bonding, which facilitates the installation of the elastic limiting block 200 and makes the installation position of the elastic limiting block 200 clear, making it more convenient for users to use.

[0046] like Figure 1 、 Figure 2 As shown, further, an annular groove 121 is provided on the outside of the bonding position 120 of this embodiment. The bonding position 120 is surrounded by the annular groove 121, making the bonding position 120 more intuitive, providing positioning when installing the elastic limit block 200, and improving installation efficiency. An identification portion 122 is provided on the surface of the area surrounded by the annular groove 121, and the identification portion 122 is used to identify the bonding position 120. By providing the identification portion 122, information prompts can be provided intuitively. For example, the identification portion 122 can identify the material type of the elastic limit block 200 that needs to be bonded, thereby avoiding errors during the installation process. The identification portion 122 can be letters formed during the injection molding process to improve the installation efficiency of the elastic limit block 200.

[0047] like Figure 2 、 Figure 3 、 Figure 4As shown, further, in this embodiment, multiple elastic limit blocks 200 are respectively arranged on both sides of the accommodating cavity 111 in the width direction and on one side in the length direction, and surround a positioning cavity 210. In the specific structure, elastic limit blocks 200 are provided on both sides (left and right) in the width direction. Since the side in the length direction is relatively long, multiple elastic limit blocks 200 can be provided on the left and right sides, and the multiple elastic limit blocks 200 are arranged at intervals along the length direction. The elastic limit blocks 200 on both sides in the width direction can be symmetrically arranged so that after limiting the mobile phone 10 on the left and right sides, the mobile phone 10 is squeezed in the middle position. The elastic limit block 200 can be provided at the first end in the length direction, and the elastic limit block 200 at the first end and the inner wall of the second end of the accommodating cavity 111 respectively abut against the bottom and top side walls of the mobile phone 10, thereby achieving the limitation of the mobile phone 10 in the length direction.

[0048] Furthermore, the elastic stoppers 200 of this embodiment are foam blocks. Foam blocks are not only low-cost but also inherently elastic, providing good protection for the sides of the phone 10. In particular, by placing foam blocks on both sides of the width, the symmetrical arrangement allows phones 10 of different sizes to be automatically centered when placed between the symmetrically arranged foam blocks, facilitating faster positioning of the phones 10.

[0049] like Figure 2 、 Figure 3 、 Figure 5 As shown, further, the shell 100 of this embodiment mainly includes: a shell 110 and an elastic telescopic member 130, the accommodating inner cavity 111 is opened on the shell 110, and the first limiting member 300 is arranged at the first end of the length direction of the shell 110; the elastic telescopic member 130 is connected to the second end of the length direction of the shell 110, and the second limiting member 400 is arranged on the elastic telescopic member 130, and the elastic telescopic member 130 can be extended and retracted along the length direction to drive the second limiting member 400 to move along the length direction. The protective film 20 is connected at both ends by the first and second stoppers 300 and 400. The elastic member 130, under the action of elastic force, stretches and separates the protective film 20 from the screen of the mobile phone 10 by a predetermined distance. 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 member 130 stretches and tightens the protective film 20, thereby creating a dust-removing space between the protective film 20 and the screen of the mobile phone 10. This facilitates the removal of dust from the screen of the mobile phone 10 within this dust-removing space during the removal process of the release layer 23, achieving a dust-removing effect. When applying the protective film, the protective film 20 is squeezed, causing the elastic member 130 to contract and force the film layer 22 on the protective film 20 downward, thereby contacting the film layer 22 with the screen of the mobile phone 10. This prevents the film layer 22 from being significantly squeezed and deformed during the downward movement, thus facilitating a smoother application process.

[0050] like Figure 2 、 Figure 3 、 Figure 4 As shown, further, the elastic telescopic member 130 of this embodiment specifically includes: a bending portion 131 and a supporting platform 132. One end of the bending portion 131 is connected to the shell 110, and the supporting platform 132 is connected to the end of the bending portion 131 away from the shell 110. The second limiting member 400 is arranged on the supporting platform 132, and the supporting platform 132 moves relative to the shell 100 through the bending of the bending portion 131. After the second limiting member 400 and the first limiting member 300 are connected and limit the protective film 20, the protective film 20 is squeezed, so that the bending portion 131 is compressed and the supporting platform 132 moves toward the first end of the shell 110, thereby reducing the distance between the first limiting member 300 and the second limiting member 400 in the length direction, so that the protective film 20 has a downward movement margin. The bending portion 131 can adopt a variety of structures, such as a complete bending elastic plate in the width direction or a plurality of bending elastic plates arranged at intervals in the width direction, etc. The bent portion 131 of this embodiment is a U-shaped structure, forming a U-shaped groove with its opening facing upward. The U-shaped bent portion 131 is used for connection, generating a stable elastic force. The width between the U-shaped grooves (the distance between the inner walls in the longitudinal direction) provides a movable position for the support platform 132, enabling the support platform 132 to have stable movement and reset functions.

[0051] like Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 As shown, further, a top platform 140 is provided at the first end of the shell 110 of this embodiment, and a first limiting member 300 is provided on the top platform 140. The top platform 140 is provided at the rear end of the shell 110, and the upper surface of the top platform 140 is flush with the upper surface of the supporting platform 132 and is higher than the upper surface of the shell 110, 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. A tear opening 141 is formed between the top platform 140 and the upper surface of the shell 110, and the tear opening 141 is used to pull out the tear release layer 23 of the protective film 20. The tear release layer 23 of the protective film 20 passes through the tear opening 141, which is convenient for the user to pull the tear release layer 23 out of the tear opening 141.

[0052] like Figure 2 、 Figure 3 、 Figure 4 、 Figure 5As shown, the first retaining member 300 of this embodiment includes at least two first hooks 310 spaced apart along the width of the top platform 140. The two first hooks 310 are respectively used to connect to the first positioning holes 21a at the first end of the positioning release layer 21 of the protective film 20. The second retaining member 400 specifically includes at least two second hooks 410 spaced apart along the width of the elastic member 130. The two second hooks 410 are respectively used to connect to the first positioning holes 21a at the second end 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.

[0053] like Figure 6 、 Figure 7 As shown, the foam-adaptive 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 can be a scraper or a roller 510. The extrusion member 500 squeezes the protective film 20, thereby stabilizing the force during the film application process. For example, by squeezing the extrusion member 500 from front to back, it is possible to effectively prevent bubbles from being generated and pushing the extrusion member 500 to squeeze the protective film 20 connected to the first stopper 300 and the second stopper 400.

[0054] Example 2

[0055] like Figure 4 、 Figure 5 、 Figure 7 As shown, this embodiment provides a film-sticking kit, including the foam-adaptable dust removal film-sticking device and the protective film 20 as described above. Figure 3 As shown, the protective film 20 includes a film layer 22, a positioning release layer 21, and a tear-off release layer 23. The positioning release layer 21 is connected to the first stopper 300 and the second stopper 400. The tear-off release layer 23 is pulled out through the tear opening 141 to align the film layer 22 with the screen of the mobile phone 10. The film layer 22 is attached to the surface of the mobile phone 10 to protect the screen.

[0056] like Figure 4 、 Figure 5 、 Figure 7 As shown, the positioning release layer 21 is detachably disposed on one side of the film layer 22. A first positioning hole 21a is provided at the rear end of the positioning release layer 21 in the first direction, and a second positioning hole 21b is provided at the front end. The first positioning hole 21a and the second positioning hole 21b respectively fit over the first hook 310 and the second hook 410 for positioning. The tear-off release layer 23 is disposed on the side of the film layer 22 facing away from the positioning release layer 21 and toward the mobile phone 10.

[0057] 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.
