[0035] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application, and should not be understood as limiting the present application.
[0036] The embodiments of the present application provide a large-curvature curved surface touch screen structure.
[0037] Please refer to Figures 1 to 8In an embodiment, the large-curvature curved touch screen 220 structure is used in an electronic cigarette. The electronic cigarette includes a housing 100 having a front mounting surface 110 on a front side and a hollow mounting cavity 120. Specifically, the large-curvature curved touch screen 220 structure includes a display screen 210 and a touch screen 220. The touch screen 220 is mounted on the front mounting surface 110 to cover the mounting cavity 120. The lens of the touch screen 220 is integrally injection molded from a plastic material, including an integrated flat area 221 and a curved area 222. The outer surface and the inner surface of the flat area 221 are both flat, and the display screen 210 is attached to the inner surface of the flat area 221. The curved area 222 is formed by extending rearwardly and arcuately from the left and right side edges and the lower end edge of the flat area 221, and in the left-right direction, the ratio of the width of the flat area 221 to the width of the curved area 222 ranges from 1 to 3. The touch screen 220 is connected to the housing 100 by bonding the inner surface of the curved area 222 to the front mounting surface 110.
[0038] Based on the above structure design, in the present embodiment, since the lens of the touch screen 220 is integrally injection molded from a plastic material, the shape is more plastic than the glass lens of the existing touch screen 220 of the electronic cigarette, and the curved area 222 can achieve a large-curvature structure design. At the same time, by attaching the display screen 210 to the inner surface of the flat area 221 and making the curved area 222 extend rearwardly and arcuately from the left and right side edges and the lower end edge of the flat area 221, the inside of the touch screen 220 can be hollowed out, which is conducive to achieving a large-curvature touch screen 220 design. In summary, through the above structure design, the large-curvature curved touch screen 220 structure can cover the front and side surfaces of the electronic cigarette housing 100, and the radius of curvature of the touch screen 220 is significantly larger than that of the touch screen 220 of the existing product, thereby providing a larger operable area and a better user interaction experience. Moreover, the large-curvature curved design makes the electronic cigarette more technologically advanced and fashionable in appearance.
[0039] In the embodiment, specifically, the lens of the touch screen 220 is integrally injection molded by PET and PC materials through an IML (In-Mold Labeling) process. Here, the IML process first preforms the transparent PET material into a 3D-shaped film, then precisely positions it in the inner cavity of the injection mold, and then injects PC molten plastic material. The film and the plastic material are fused and solidified under high temperature and high pressure, and after demolding, the lens of the touch screen 220 with a hardened transparent film on the surface and a plastic on the bottom is obtained. The plastic part made by the IML process has the advantages of good surface wear resistance, high design freedom to support complex 3D curved surfaces, integrated molding to reduce assembly links, and the ability to integrate touch control circuits. In addition, compared with thicker glass lenses, plastic lenses can be thinner, thereby saving space and making the structure of the electronic cigarette more compact. Of course, in other embodiments, other suitable plastic materials can also be used, which are not particularly limited here. It should be noted that the electronic cigarette also includes other related components, such as an atomizing core built into the mounting cavity 120 and a mouthpiece provided on the upper end of the shell 100. These existing components are not shown in the figure.
[0040] Referring to Figure 3 and Figure 4 In the embodiment, in the left-right direction, the width of the flat area 221 is a, and in the direction from one side edge of the flat area 221 to the outer edge of the curved area 222 on the same side, the radius of curvature of the curved area 222 is b; b is gradually increased; the ratio of a to b ranges from 1 to 6. In other words, the degree of arc bending of the curved area 222 is more moderate as it is closer to the side surface of the shell 100, so that the appearance of the curved touch screen is more rounded and beautiful, and the user experience is better.
[0041] Further, as shown in Figure 3 In the embodiment, the display screen 210 is completely bonded to the inner surface of the flat area 221 by optical glue or liquid optical glue. Here, the structure of the large-curvature curved touch screen 220 is selected by full bonding process, that is, the touch screen 220 and the display screen 210 are completely bonded by optical glue or liquid optical glue, without air layer between them. In this way, it is beneficial to improve the display effect and reduce reflection, while improving brightness and clarity, so that the touch control experience is faster and the operation is smoother.
[0042] Further, as shown in Figure 5 and Figure 8As shown, in the present embodiment, a plurality of reinforcing ribs 223 are arranged on the side edge of the inner surface of the flat plate area 221 and the corresponding curved area 222, and the reinforcing ribs 223 are arranged in the up-down direction. In the actual electronic cigarette, in order to facilitate the installation of related components, the shell 100 is designed to be hollow at the position corresponding to the reinforcing ribs 223. Therefore, in order to avoid the concave condition caused by pressing the side of the touch screen 220, a plurality of reinforcing ribs 223 arranged in the up-down direction are arranged to strengthen the support strength of the position.
[0043] Further, as shown in Figure 8 In the present embodiment, the inner wall surface of the curved area 222 on the other side of the flat plate area 221 is provided with a hollow groove 224 and a demolding groove 225. The hollow groove 224 is arranged on the upper region of the inner wall surface of the curved area 222, and the hollow groove 224 is arranged in the shape of a long strip with the length extending direction being the up-down direction. The demolding groove 225 is arranged adjacent to the lower end of the inner wall surface of the curved area 222. Here, the hollow groove 224 is arranged to avoid the internal structure at the corresponding position, and the demolding groove 225 is a virtual buckle arranged on the injection mold, which can play a certain role in demolding the mold.
[0044] Further, as shown in Figures 3 to 7 In the present embodiment, the inner surface of the touch screen 220 is provided with a first bonding area 226 at the upper end, and the upper end of the front mounting surface 110 is provided with a second bonding area 111 corresponding to the position of the first bonding area 226. The first bonding area 226 and the second bonding area 111 are bonded by adhesive. In this way, the design of the second bonding area 111 can increase the bonding area on the front mounting surface 110, so that the upper end of the touch screen 220 and the upper region of the front mounting surface 110 of the shell 100 can be better bonded together, and the touch screen 220 is less likely to fall off. In addition, the thickness of the lens of the touch screen 220 at the first bonding area 226 is thinner, because the size of the electronic cigarette and the size of the cartridge are limited, and the thickness of the lens of the touch screen 220 needs to be reduced.
[0045] Further, as shown in Figure 6 and Figure 7 In the present embodiment, the left and right side edges of the mounting cavity 120 are provided with support tabs 130 protruding towards the touch screen 220, and the curved areas 222 on the left and right inner wall surfaces are bonded with the support tabs 130. It can be understood that the arrangement of the left and right support tabs 130 can increase the bonding area between the touch screen 220 and the side surface of the shell 100, thereby facilitating the connection firmness between the two; on the other hand, the support tabs 130 can also play a certain supporting role on the side edge of the lens of the touch screen 220, so as to avoid the situation that the side edge is easily pressed down when pressed.
[0046] Further, as shown inFigures 5 to 8 As shown, in the present embodiment, the electronic cigarette further comprises a lower end connector 300, a front end of the lower end connector 300 is bonded with an inner wall surface of a lower end of the curved surface area 222, and a rear end of the lower end connector 300 is detachably connected with the lower end of the shell 100. Specifically, a screw hole 140 is arranged at a bottom of the mounting cavity 120 of the shell 100, and the lower end connector 300 is screwed into the screw hole 140 to achieve detachable connection with the shell 100. However, the present design is not limited thereto, and the lower end connector 300 can also be detachably connected with the shell 100 through other suitable manners, but in the present embodiment, the screw connection manner between the lower end connector 300 and the shell 100 has the advantages of more stable connection and more convenient disassembly. In the actual assembly process, the lower end connector 300 can be first fixed with a screw at the lower end of the mounting cavity 120, and then the touch screen 220 with the display screen 210 attached thereon is bonded with the shell and the lower end connector 300.
[0047] The present application also proposes an electronic cigarette, which comprises the aforementioned large-curvature curved touch screen structure, and the specific structure of the large-curvature curved touch screen structure refers to the above-mentioned embodiments. Since the electronic cigarette adopts all the technical solutions of the above-mentioned embodiments, it also has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here.
[0048] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
