Description

Technical Field

[0001] This utility model relates to the field of film application tools, specifically a high-efficiency air-venting film applicator and an integrated film application packaging box. Background Technology

[0002] With the widespread use of smartphones, screen protectors have become an important way for people to protect their phone screens. A key step in the application process is ensuring that air is expelled from the screen protector to achieve a tight seal.

[0003] Traditional screen protector application methods typically rely on manually squeezing out air bubbles, which is not only time-consuming and laborious but also prone to creating air bubbles under the screen protector. For example, when using a regular screen protector, users need to carefully apply it from one end to the other, trying to avoid air getting trapped between the screen protector and the screen. Once air bubbles appear, the screen protector needs to be repeatedly peeled off to release the air, which affects the quality of the application and may also cause wear and tear on the screen protector surface.

[0004] To address this issue, various screen protector application tools have emerged on the market. Some of these tools significantly improve efficiency and quality by providing auxiliary venting during the application process. However, existing screen protector applicators suffer from several flaws in their venting channel design. For example, some applicators have their venting channels positioned in the center, making it easy for air bubbles to form when venting from the center outwards. Specifically, when the venting channel is in the center, air converges from the edges towards the central venting channel during application. However, since the screen protector adheres to the phone screen from the edge, the airflow is hindered by friction between the screen protector and the screen, as well as the air's own cohesive force. This prevents the air from escaping smoothly and promptly, creating localized air stagnation areas between the screen protector and the screen, which are prone to air bubbles. For instance, in the corners of the screen protector, air may become trapped because it cannot quickly flow to the central venting channel, forming bubbles. Furthermore, improperly designed venting channels, with their ineffective airflow guidance, result in poor venting performance.

[0005] Therefore, it is necessary to propose an improved technical solution to address the above problems. Utility Model Content

[0006] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0017] The present application also provides a film integrated packaging box, which applies the above-mentioned efficient exhaust film pasting device and further comprises a box body having a containing space, and the film pasting base is arranged inside the box body.

[0018] As a further scheme of the present application, the box body has a bottom plate and a cover plate rotatably connected to one end of the bottom plate, so that the box body has two states of opening and closing.

[0019] The bottom plate is integrally connected with a positioning frame to form the film pasting base, and the exhaust passage is formed at the inner edge region of the positioning frame along the length direction of the bottom plate.

[0032] The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0033] Referring to Figure 1 The utility model discloses an efficient exhaust film pasting device, comprising:

[0034] The film pasting base 1 has a placing area 2 for placing a mobile phone.

[0035] The exhaust channel 3 is arranged at the edge area of the film pasting base 1 and extends along the length direction of the film pasting base 1, and is used for pressing and exhausting the air between the film and the mobile phone screen after film pasting is completed, so that the film is tightly attached to the mobile phone screen.

[0036] During the film pasting process, air is squeezed out from the gap between the film and the mobile phone screen. The exhaust channel 3 is arranged at the edge of the film pasting base 1 and extends along the length direction, which utilizes the natural flow direction of the air between the film and the screen. When the film is attached from one end to the other end, the air is squeezed towards the edge. The exhaust channel 3 provides a concentrated exhaust path, so that the air can be quickly exhausted along the length direction.

[0037] The air in the space between the film and the screen flows along the attachment direction of the film. During the film pasting process, due to the longer length of the long side of the mobile phone screen, the attachment operation from one end to the other end during film pasting causes the air to be squeezed, and the long side direction provides a wider diffusion space for the air, so that the air tends to flow along the long side direction. The exhaust channel 3 is arranged along the length direction, which conforms to the natural flow direction of the air, so that the air can be more smoothly exhausted. Furthermore, because the air at the middle position needs to overcome the friction between the surrounding film and the screen and the cohesion of the air itself to reach the exhaust channel 3, while at the edge, the air can directly enter the exhaust channel 3 from the gap between the edge and the screen, thereby reducing the resistance of air flow, so that the air can be more smoothly exhausted.

[0038] The design of the exhaust channel 3 enables the air to be concentratedly exhausted along the length direction when being squeezed. When the film is attached from one end to the other end, the air is squeezed towards the edge. The exhaust channel 3 provides a concentrated exhaust path for the air, avoiding the dispersion of the air between the film and the screen, thereby improving the exhaust efficiency.

[0039] The design of the film pasting device makes the pressure distribution uniform during the film pasting process. By pressing the air exhaust channel 3, uniform pressure can be generated on the air between the film and the screen, avoiding excessive local pressure that causes air to be unable to be exhausted or bubbles to be generated. Specifically, during the film pasting process, by pressing the air exhaust channel 3, uniform pressure can be generated on the air between the film and the screen. This uniform pressure enables the air to be uniformly exhausted when being pressed, avoiding excessive local pressure that causes air to be unable to be exhausted or bubbles to be generated. That is, the design of the air exhaust channel 3 can transmit pressure to the air between the film and the screen. When the air exhaust channel 3 is pressed, pressure is transmitted to the air along the channel, so that the air can be pressed and exhausted.

[0040] In summary, by arranging the air exhaust channel 3 at the edge and extending along the length direction, the air between the film and the screen of the mobile phone can be quickly and effectively exhausted. Compared with the traditional film pasting device, the design of the air exhaust channel 3 can better guide the air to be exhausted, reducing the generation of bubbles. The design of the air exhaust channel 3 can avoid the accumulation of air in the middle of the film, thereby reducing the generation of bubbles. During the film pasting process, the air is exhausted from the edge, so that the film can be more tightly attached to the screen, improving the quality of the film pasting. The design of the film pasting device makes the air exhaust operation more simple and convenient. The user only needs to press the air exhaust channel 3 after the film pasting is completed, so that the air can be exhausted without complex operation steps.

[0041] In the embodiment of the utility model, the edge of the film base 1 is provided with a raised frame 4, and the frame 4 surrounds to form the placing area 2.

[0042] The air exhaust channel 3 is located at the inner edge area of the frame 4.

[0043] The frame 4 surrounds to form the placing area 2. When the air is pressed to the edge during the film pasting process, the frame 4 can guide the air to flow along the inner edge area of the frame 4. The existence of the frame 4 plays a certain restraining role, so that the air is concentrated and guided to the air exhaust channel 3 within a certain range. This is because the frame 4 forms a relatively closed space, and the flow of air in this space is limited by the frame 4, so that the air tends to flow along the inner edge of the frame 4.

[0044] The frame 4 provides structural support for the film pasting device, ensuring the stability of the mobile phone during the film pasting process. The height and thickness of the frame 4 can prevent the mobile phone from shaking or shifting during the placing process, ensuring the relative position stability between the air exhaust channel 3 and the screen of the mobile phone. At the same time, the rigidity of the frame 4 can withstand a certain pressure, so that the film pasting device is not easy to deform during the operation process, thereby ensuring the normal work of the air exhaust channel 3.

[0045] The setting of the frame 4 can prevent air from leaking out of the edge of the film applicator, and during the film application process, air is pressed towards the edge, and if there is no blockage of the frame 4, air may escape from other positions of the edge, affecting the exhaust effect, and the frame 4 limits the air to the inside edge area of the frame 4, ensuring that the air can be discharged through the exhaust channel 3, and improving the exhaust efficiency.

[0046] In the embodiment of the utility model, the both ends of exhaust channel 3 are provided with flared structure 5, the shape of flared structure 5 is one of horn shape, arc shape or trapezoidal shape.

[0047] The design of flared structure 5 makes the both ends of exhaust channel 3 open horn shape, arc shape or trapezoidal shape, and this shape can guide air to enter exhaust channel 3 more smoothly, when air is pressed between the film and the screen, the horn shape, arc shape or trapezoidal shape of flared structure 5 can expand the inlet area of air, so that air can more easily gather in exhaust channel 3, for example, the flared structure 5 at both ends of exhaust channel 3 is like a funnel, which can guide air from a larger space range to a smaller channel, thereby improving the exhaust efficiency.

[0048] The shape of flared structure 5 can reduce the resistance of air when entering exhaust channel 3, and the horn shape, arc shape or trapezoidal shape of flared structure 5 makes air have a gradual transition process when entering exhaust channel 3, avoiding the sudden contraction or collision of air at the inlet, thereby reducing the resistance of air flow, which helps air to flow quickly in exhaust channel 3 and improves the exhaust speed.

[0049] Flared structure 5 can increase the effective area of exhaust channel 3, and the horn shape, arc shape or trapezoidal shape of flared structure 5 makes exhaust channel 3 form a larger space at the opening of both ends, and air can exchange and discharge more fully in this space, which helps to improve the exhaust capacity of exhaust channel 3 and ensures that air between the film and the screen can be discharged more thoroughly.

[0050] In the embodiment of the utility model, the inlet of exhaust channel 3 is chamfered or flared (such as the back of the film applicator).

[0051] The chamfering or flaring treatment at the inlet of exhaust channel 3 can guide air to enter exhaust channel 3 more smoothly, and when air is pressed between the film and the screen, the shape of chamfering or flaring can change the flow direction of air, so that air is more easily gathered to the channel inlet, for example, the flaring at the inlet of exhaust channel 3 is like a funnel, which guides air from a larger space range to a smaller channel inlet, thereby improving the exhaust efficiency.

[0052] In the embodiment of the utility model, the cross-sectional shape of exhaust channel 3 is rectangular, and the inner wall is a smooth surface.

[0053] The rectangular cross-sectional shape helps to evenly distribute pressure, and when the air is extruded into the exhaust passage 3, the rectangular shape of the exhaust passage 3 enables the pressure to act evenly on the air, which avoids the pressure being concentrated in a certain point or area, ensuring the stable flow of air in the passage;

[0054] The smooth surface can reduce the resistance of air flow, and when the air flows in the exhaust passage 3, the smooth inner wall reduces the friction between the air and the passage wall, so that the air can pass through the passage more quickly, which is beneficial to improve the exhaust efficiency and make the air be discharged more smoothly.

[0055] In the embodiment of the utility model, the starting end of the exhaust passage 3 is close to the edge of the placing area 2.

[0056] The starting end of the exhaust passage 3 is close to the edge of the placing area 2, so that when the air is extruded from the edge of the screen and the film during the film pasting process, it can directly enter the exhaust passage 3, and when the film is pasted on the screen from the placing area 2, the air is extruded to the edge, at this time, the starting end of the exhaust passage 3 is like an "entrance", which can timely capture the air and provide a direct and smooth exhaust path for the air.

[0057] This design can improve the exhaust efficiency, because the air at the initial position between the film and the screen can directly enter the exhaust passage 3, avoiding the accumulation of air at other positions between the film and the screen, reducing the situation that the air needs to be discharged through other paths during the film pasting process, so that the air can be discharged more quickly; the starting end of the exhaust passage 3 close to the edge of the placing area 2 also helps to ensure the pasting effect of the film, and the air can be discharged in time during the film pasting process, so that the film can be more closely pasted on the screen, reducing the air residue between the film and the screen, thereby improving the quality of the film.

[0058] In the embodiment of the utility model, the length L1 of the exhaust passage 3 and the length L2 of the film base 1 satisfy L1 / L2>1 / 2, and the exhaust passage 3 is located in the central region of the length direction of the film base 1.

[0059] The ratio of the length of the exhaust passage 3 to the length of the film base 1 is greater than 1 / 2, which means that the exhaust passage 3 can cover most of the area in the long edge direction of the screen, and when the film is pasted from one end to the other end, the air is extruded in the long edge direction, and the exhaust passage 3 can provide an exhaust path on the entire long edge length and is located in the central region of the length direction of the film base 1, so that the exhaust passage 3 can more evenly extrude and discharge the air between the film and the screen during the exhaust process, because the central position can ensure that the exhaust passage 3 is relatively balanced in distance from each part of the screen, and the air can flow more evenly into the passage when being extruded, avoiding the situation that the local air is not discharged smoothly.

[0060] The exhaust channel 3 is long and located in the central area, which helps to form a uniform pressure distribution during the film pasting process. When the exhaust channel 3 is pressed, the pressure can be evenly transmitted to the air between the film and the screen, so that the air is squeezed and discharged in the whole length direction. This uniform pressure distribution can improve the exhaust efficiency, reduce the air residue between the film and the screen, and ensure that the film can be tightly attached to the screen.

[0061] The proportional relationship between the length of the exhaust channel 3 and the length of the film base 1 and its central position can better adapt to different sizes and shapes of mobile phone screens. Whether the long side of the mobile phone screen is long or short, the exhaust channel 3 can cover the edge area of the screen to a certain extent, meeting the exhaust needs of different mobile phone screens.

[0062] Please refer to Figures 2-4 The utility model also proposes a film integrated packaging box which applies the above-mentioned high-efficiency exhaust film pasting device and further comprises a box body 6, the box body 6 has containing space, the film base 1 is arranged in the box body 6 inside, the box body 6 has bottom plate 7 and the cover plate 8 of rotation connection on the one end of bottom plate 7, to make the box body 6 have two kinds of state of opening and closing,

[0063] The bottom plate 7 is integrally connected with a positioning frame 9 (that is, the above-mentioned frame 4), to form the film base 1, and the exhaust channel 3 is formed in the length direction of the bottom plate 7 and located in the inner side edge area of the positioning frame 9.

[0064] As the authorized patent previously submitted by the applicant, the "packaging box integrated with film pasting function" with the publication number CN221852318U, the packaging box itself is used as the packaging box of the film / film pasting device, and also can be used as the film pasting device, realizes the integration of packaging function and film pasting function, thereby effectively saving the cost. On this basis, by setting the exhaust channel 3 in the edge area, the air exhaust during the film pasting process is ensured, and the film pasting quality is improved.

[0065] For those skilled in the art, it is obvious that the utility model is not limited to the details of the above-mentioned exemplary embodiments, and can be realized in other specific forms without departing from the spirit or basic characteristics of the utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, the scope of the utility model is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the utility model.
