Description

Technical Field

[0001] This application relates to the field of atomization technology, and in particular to a flexible screen assembly and an electronic atomizer. Background Technology

[0002] As a common portable electronic device, electronic atomizers often employ cylindrical or curved surfaces for their casings to ensure a comfortable grip and aesthetically pleasing design. To enable functions such as displaying device status and adjusting parameters, electronic atomizers typically include a screen to enhance the user experience.

[0003] Most current e-cigarettes use traditional flat-panel displays, which have significant technical drawbacks in practical applications. Firstly, the flat structure of the display cannot be directly fitted to the curved shell of the e-cigarette, requiring additional flat installation space. This not only increases the overall size of the e-cigarette but also limits the design freedom of the curved shell, making it difficult to balance portability and aesthetics. Secondly, the light guide structure of flat-panel displays is often rigid, with a fixed shape that cannot adapt to the shape of the curved shell. When used in curved installation scenarios, the light guide path is easily affected by the curved surface, resulting in uneven light distribution and issues such as uneven brightness and color banding, severely impacting display quality and user experience. Thirdly, flat-panel displays have limited viewing angles, only visible from the front, failing to meet users' needs to view the e-cigarette's status (such as battery level and e-liquid level) from multiple angles.

[0052] The flexible screen component of this application has the following beneficial effects: (1) Breakthrough viewing angle: It can realize the 360° full viewing angle display of the electronic atomizer, and users can view the status of the electronic atomizer from any angle, solving the problem of limited viewing angle of traditional flat display screens; (2) Strong adaptability: It can fit the shell component of the curved electronic atomizer, and the shell component does not need to reserve additional planar space, which helps the electronic atomizer to achieve a more compact and beautiful appearance design; (3) Uniform light guide: The light guide layer is a flexible design, and its shape can adapt to the curved shape of the shell component, and the light guide path of the light guide layer will not be affected by the curved shape, resulting in a good display effect.

[0053] Please see Figures 2 to 8 The following will mainly describe the specific structure of the flexible screen component 100.

[0054] The flexible screen assembly 100 of this application includes a base layer 110, which is a flexible base layer 110. The base layer 110 is made of highly flexible polyimide (PI) material and / or polyethylene terephthalate (PET) material, and the thickness of the base layer 110 is 0.1-0.3 mm. Therefore, the base layer 110 can freely deform to conform to the cylindrical, arc-shaped, or other curved shell components of the electronic atomizer 10, both tightly fitting the curved shell components, reducing the overall volume of the electronic atomizer 10, and freeing up the design freedom of the shell components, balancing portability and aesthetics. The 0.1-0.3 mm thickness design is in line with the miniaturized product positioning of the electronic atomizer 10, and will not cause bulkiness due to additional thickness of the base layer 110. PI and PET materials have both good mechanical strength and temperature resistance, and even with a thickness of only 0.1-0.3 mm, they can provide a stable load-bearing foundation. Meanwhile, the tensile and bending resistance of PI and PET materials can prevent interlayer delamination of the flexible screen assembly 100 during assembly or use, ensuring the structural integrity of the flexible screen assembly 100. The base layer 110 includes a connecting side, which includes an adjacent first connecting area and a second connecting area. The base layer 110 is used to provide installation.

[0055] The flexible screen assembly 100 of this application includes a light-emitting module 120, which is located in the first connection area. The light-emitting module 120 provides a light source and includes a flexible printed circuit board (FPC) 121 and LED beads 122. The FPC 121 is the core support and signal transmission carrier of the light-emitting module 120, and is directly attached (or bonded) to the first connection area of ​​the substrate 110. The FPC 121 provides an installation reference for the LED beads 122 and undertakes the signal transmission task. Its design fully matches the bending characteristics of the flexible screen. The LED beads 122 are the core components for generating the light source. To adapt to the display requirements of flexible scenes and electronic atomizers 10, a miniaturized and low-power design can be adopted. The LED beads 122 can be Mini LED or Micro LED beads. The emission wavelength of the LED beads 122 is matched according to the display requirements. The LED beads 122 can be soldered to the soldering area of ​​the flexible substrate using a flip-chip bonding process. Each light-emitting module 120 includes at least one LED bead 122, which are arranged in a matrix.

[0056] The flexible printed circuit board 121 includes a board body 121a and a connector 121b. An LED bead 122 is disposed on the board body 121a. One end of the connector 121b is connected to the board body 121a, and the other end of the connector 121b is used for electrical connection to the control chip of the electronic atomizer 10. The connector 121b can be flexible, and its flexible circuit structure ensures signal transmission stability during bending. The connector 121b can be made of highly flexible polyimide material, with a core of multi-strand ultra-fine silver-plated copper wire, capable of withstanding more than 100,000 bends without breakage. Please refer to [link / reference]. Figure 6The end of the connector 121b away from the plate 121a is provided with a standardized terminal, which is used to achieve a stable electrical connection with the control chip of the electronic atomizer 10. The connector 121b may be wrapped with an insulating heat-resistant sleeve to prevent the connector 121b from short-circuiting or being damaged by the atomizing components (high-temperature heating) of the electronic atomizer 10.

[0057] The flexible screen assembly 100 of this application includes a shielding layer 130, which is disposed on the side of the light-emitting module 120 opposite to the first connection area. The shielding layer 130 is used to selectively shield a portion of the light-emitting module 120 so that the light emitted by the LED beads 122 is emitted only from the defined area. The shielding layer 130 can be made of foam material, and a light-blocking agent is added to the foam material. The light-blocking agent can be a high-concentration light-blocking agent, such as carbon black or titanium dioxide. The light-blocking agent fills the internal pores of the foam and absorbs / reflects light, thereby achieving precise shielding of non-target areas of the light-emitting module 120. The foam has both flexibility and light-blocking properties, and can deform synchronously with the flexible printed circuit board 121 to adapt to the curved surface installation requirements of the flexible screen assembly 100. The foam can be precisely aligned with the matrix of LED beads 122 through a die-cutting process to ensure that the LED bead area is exposed and the non-LED bead area is completely shielded.

[0058] The flexible screen assembly 100 of this application includes a reflective layer 140, which is disposed in the second connection area and adjacent to the light-emitting module 120. The reflective layer 140 is used to receive the light emitted by the lamp bead 122 and reflect the light out of the reflective layer 140 on the side away from the base layer 110.

[0059] The reflective layer 140 is tightly bonded to the second connection area and adjacent to the light-emitting module 120. The bonding between the reflective layer 140 and the second connection area can be achieved using flexible pressure-sensitive adhesive, ensuring a tight, bubble-free bond and facilitating easy removal and replacement during maintenance. The reflective layer 140 captures light emitted from the LED chip 122 towards the base layer 110 and efficiently reflects it to the light guide layer 150. The reflective layer 140 can use a flexible PET or PI film as the substrate, ensuring that the reflective layer 140 deforms synchronously with the curvature of the base layer 110 without wrinkling. The substrate of the reflective layer 140 facing the light-emitting module 120 can be laminated with a high-reflectivity functional layer. The bottom layer of the reflective functional layer can be an aluminum vapor deposition layer. The aluminum vapor deposition layer utilizes the high specular reflection characteristics of metal to achieve basic reflectivity. The surface layer of the reflective functional layer can be a white diffuse reflection coating (the material can be titanium dioxide modified acrylic resin). The white diffuse reflection coating can convert the direct light of the lamp bead 122 into uniform diffuse reflection light, avoid the formation of local bright spots by the reflected light, and improve the light uniformity of the light guide layer 150.

[0060] The side of the reflective layer 140 facing the light guide layer 150 can be fabricated into a matrix microstructure array (the structure type can be a microprism or a hemispherical bump) using a micro-nano imprinting process. This design can change the propagation angle of the reflected light, so that the reflected light enters the light guide layer 150 obliquely, which matches the total internal reflection condition of the light guide layer 150.

[0061] The portion of the reflective layer 140 adjacent to the light-emitting module 120 extends toward the light-emitting module 120 to form an adhesive portion, and the edge of the light-emitting module 120 is adhesively bonded between the first connection area and the adhesive portion. As a result, the connection between the reflective layer 140, the light-emitting module 120, and the first connection area is relatively firm.

[0062] The flexible screen assembly 100 of this application includes a light guide layer 150, which is disposed on the side of the reflective layer 140 away from the second connection area. The light guide layer 150 is used to conduct light reflected by the reflective layer 140 and to homogenize the light.

[0063] The portion of the light guide layer 150 adjacent to the light-emitting module 120 extends towards the light-emitting module 120 and connects between the light-emitting module 120 and the shielding layer 130. The portion of the light guide layer 150 that connects to the edge of the flexible printed circuit board 121 without the LED beads 122 is also included. Therefore, the connection between the light guide layer 150, the reflective layer 140, and the light-emitting module 120 is relatively strong. The shape of the portion of the light guide layer 150 that connects to the flexible printed circuit board 121 can be adapted to the shape of the portion of the flexible printed circuit board 121 without the LED beads 122.

[0064] Please see Figure 7 and Figure 8 A matrix-like microstructure light guide dot pattern 151 is formed on the side of the light guide layer 150 facing the reflective layer 140. The light guide layer 150 can receive direct light from the light-emitting module 120 and reflected light from the reflective layer 140, achieving light homogenization and directional emission through the matrix-like microstructure light guide dot pattern 151. The substrate of the light guide layer 150 can be made of a high-transmittance flexible polymer material (such as PMMA or PC) with a light transmittance ≥92%, and the light guide layer 150 can deform synchronously with the curvature of the base layer 110. The substrate of the light guide layer 150 can undergo anti-yellowing treatment, such as adding anti-UV agents (such as benzotriazoles), which can prevent the light transmittance of the light guide layer 150 from decreasing after long-term use.

[0065] The diameter of the matrix-type microstructure light guide dots 151 can be 5–20 μm, and the spacing between the matrix-type microstructure light guide dots 151 can be 10–30 μm. The matrix-type microstructure light guide dots 151 are located on the side of the light guide layer 150 facing the reflective layer 140, and can be fabricated using laser engraving or micro / nano imprinting processes. The spacing of the matrix-type microstructure light guide dots 151 is approximately in a 1:2 ratio to their diameter, ensuring seamless light coverage.

[0066] Please see Figure 7 and Figure 8 The matrix-type microstructure light guide dots 151 can be frustum-shaped, and the matrix-type microstructure light guide dots 151 taper away from the reflective layer 140. The matrix-type microstructure light guide dots 151 can be aligned one-to-one with the matrix-type microstructure array of the reflective layer 140, so that the reflected light is perpendicularly incident on the matrix-type microstructure light guide dots 151, and the scattering uniformity is high.

[0067] The light guide layer 150 is doped with at least one of red, green, and blue fluorescent particles, thereby enabling the light source to control its color. The particle size of the fluorescent particles can be controlled between 1 and 3 μm and can be prepared using an ultrasonic dispersion process, which ensures uniform distribution of the fluorescent particles and avoids color unevenness caused by particle agglomeration.

[0068] The flexible screen assembly 100 of this application includes a protective layer 160, which is disposed on the side of the light guide layer 150 opposite to the reflective layer 140. The protective layer 160 is used to protect the light guide layer 150. The protective layer 160 is a direct protective structure for the light guide layer 150 and can protect the light guide layer 150 through physical isolation and material properties.

[0069] The protective layer 160 can be made of transparent polycarbonate (PC). Transparent polycarbonate has four major advantages: First, high light transmittance, with a transmittance of ≥90%, allowing the uniform light from the light guide layer 150 to pass through without loss, without affecting display brightness and color reproduction; second, excellent impact resistance, with an impact strength more than 200 times that of ordinary glass, which can withstand possible drops and collisions during the use of the electronic atomizer 10 to prevent damage to the light guide layer 150; third, good temperature resistance, with an operating temperature range of -40℃ to 120℃, which can be adapted to the working environment of the electronic atomizer 10 and avoid deformation caused by high temperature; fourth, it has a certain degree of flexibility, with a bending radius of 3-5mm, which can deform synchronously with the light guide layer 150 and the base layer 110 without cracking or detaching due to bending.

[0070] The portion of the protective layer 160 adjacent to the light-emitting module 120 extends toward the light-emitting module 120 and connects between the light guide layer 150 and the shielding layer 130. Therefore, the connection between the protective layer 160, the light guide layer 150, and the shielding layer 130 is relatively strong. The protective layer 160 and the shielding layer 130 can be bonded together.

[0071] The protective layer 160, facing away from the light guide layer 150, is coated with an AF anti-fingerprint film. The AF anti-fingerprint film has a hardness greater than or equal to 3H, allowing it to withstand daily touch and friction without scratching. The AF anti-fingerprint film has low surface energy (surface contact angle ≥110°), effectively repelling fingerprints, oils, and water stains, achieving a wipe-free anti-fouling effect, while maintaining a light transmittance ≥98% without altering display colors. Both the protective layer 160 and the AF anti-fingerprint film can undergo e-liquid corrosion resistance treatment. For example, the protective layer 160 can be processed using a "substrate modification + surface sealing" process to block the gaps between PC molecules, preventing the penetration of nicotine, propylene glycol, and other components in e-liquid; the AF anti-fingerprint film can use a composite coating containing fluorocarbon chains, where the strong oleophobic properties of fluorine can prevent e-liquid adhesion without diminishing its anti-fingerprint performance.

[0072] In some embodiments, a pattern layer is provided between the protective layer 160 and the AF anti-fingerprint film. The pattern layer, sandwiched between the protective layer 160 and the AF anti-fingerprint film, can be prepared using flexible transparent ink (such as UV-curable acrylic ink) via inkjet printing or screen printing. The ink can be printed with brand logos, decorative textures, or functional markings as needed, and contains tar-resistant additives and anti-yellowing agents to ensure long-term colorfastness and prevent blurring.

[0073] The base layer 110 has an adhesive layer coated on the side opposite to the connection side, and the adhesive layer is bonded to the base layer 110 as a whole. The flexible screen assembly 100 includes a bottom layer, one side of which is detachably bonded to the side of the adhesive layer opposite to the base layer 110. The adhesive layer can be bonded to the base layer 110 as a whole by a hot pressing process, and the bonding surface between the bottom layer and the adhesive layer can be treated with a silicone oil coating to ensure temporary fixation during assembly. During the assembly of the flexible screen assembly 100, after the bottom layer of the flexible screen assembly 100 is removed, the flexible screen assembly 100 is bonded to the housing assembly of the electronic atomizer 10 through the adhesive layer.

[0074] The flexible screen assembly 100 of this application includes an edge-sealing sleeve 170. The edge-sealing sleeve 170 is adhered to the same-side edge of the reflective layer 140, the light-guiding layer 150, and the protective layer 160. A second connection area is adhered to the side of the edge-sealing sleeve 170 away from the reflective layer 140 (without affecting the adhesion between the reflective layer 140 and the housing assembly). The edge-sealing sleeve 170 is used to block light from escaping from the same-side edge of the reflective layer 140, the light-guiding layer 150, and the protective layer 160. The edge-sealing sleeve 170 forms a complete closed-loop light protection, preventing light leakage from the edge of the second connection area, while simultaneously strengthening the edge fixation of each functional layer. The edge-sealing sleeve 170 can be made of black flexible silicone, which combines flexibility and structural support, allowing it to deform synchronously with the curved surface of the base layer 110 without cracking. A high concentration of carbon black light-blocking agent is added to the interior of the black flexible silicone, completely blocking light penetration. The edge sealing sleeve 170 can also be attached to the same side edge of the base layer 110, reflective layer 140, light guide layer 150 and protective layer 160.

[0075] The first connecting area is located in the middle of the top or bottom edge of the second connecting area. The first connecting area is semi-circular, semi-elliptical, or semi-racetrack shaped, with its curved edge facing inwards towards the second connecting area. This design has several core advantages: First, it ensures balanced stress distribution. The symmetrical layout of the first connecting area along the centerline of the second connecting area allows the stress of the flexible screen component 100 to be evenly distributed along the centerline when bent, reducing local stress concentration. Second, it promotes coordinated light guidance. The curved edge of the first connecting area facing inwards towards the second connecting area allows for a smooth transition with the reflective layer 140 of the second connecting area, optimizing the light transmission path from the light-emitting module 120 to the reflective layer 140 and reducing light reflection loss. Third, it ensures assembly compatibility. The standardized shape and symmetrical position reduce the alignment difficulty between the light-emitting module 120 and the base layer 110. The base layer 110 (i.e., the connecting side) can be square, and the second connecting area is based on the shape of the first connecting area. The shapes of the light-emitting module 120 and the shielding layer 130 are adapted to the shape of the first connecting area and can also be semi-circular, semi-elliptical, or semi-racetrack shaped.

[0076] A clearance notch 111 is provided at the straight edge of the first connection area connecting the light-emitting module 120. The shape of the light-emitting module 120 is adapted to the opening of the clearance notch 111. The insertion wire 121b is located at the clearance notch 111, with one end extending out of the clearance notch 111 away from the plate 121a. The edge shape of the light-emitting module 120 is adapted to the contour of the clearance notch 111, enabling a tight fit between the two and avoiding structural interference. The combination design of the clearance notch 111 and the insertion wire 121b optimizes the assembly space, ensures stable signal connection, and does not occupy the volume of the additional electronic atomizer 10. The shape of the shielding layer 130 can also be adapted to the opening of the clearance notch 111, thereby enabling a tight fit between the shielding layer 130 and the light-emitting module 120 and avoiding structural interference.

[0077] The shape of the clearance notch 111 can be semi-circular, semi-elliptical, or semi-racetrack-shaped, with the arc-shaped edge of the clearance notch 111 opposite to the arc-shaped edge of the first connecting area. The arc-shaped edge of the clearance notch 111 has no sharp corners, naturally conforming to the flexible material of the insertion cable 121b, preventing the insertion cable 121b from being scratched or damaged by sharp corners when it passes through; simultaneously, the arc-shaped contact surface disperses the force on the insertion cable 121b, reducing stress concentration during bending or vibration, and extending the service life of the insertion cable 121b. The arc-shaped edge of the clearance notch 111 opposite to the arc-shaped edge of the first connecting area forms a compact "arc-to-arc" layout, requiring no additional clearance space and perfectly fitting the small-volume design of the electronic atomizer 10. The regular arc-shaped edge of the clearance notch 111 is easily achieved through die-cutting or laser cutting, with relatively small arc processing errors, ensuring precise fit with the edge of the light-emitting module 120.

[0078] A limiting notch 112 is provided on the side of the second connecting area opposite to the first connecting area. The shapes of the reflective layer 140, light guide layer 150, and protective layer 160 are adapted to the opening of the limiting notch 112. The shape of the limiting notch 112 can be square, U-shaped, or trapezoidal, etc. The edge contours of the reflective layer 140, light guide layer 150, and protective layer 160 are adjusted synchronously with the opening of the limiting notch 112, thereby ensuring interlayer alignment and tight fit. The limiting notch 112 is connected to the protruding structure of the shell assembly of the electronic atomizer 10 to realize the positioning and fixation of the flexible screen assembly 100, preventing displacement after assembly. The position of the limiting notch 112 is adapted to the connection position of the flexible screen assembly 100 in the electronic atomizer 10, and is not specifically limited.

[0079] The number of first connection areas is one. Alternatively, the number of first connection areas is at least two, with at least two first connection areas arranged circumferentially in the second connection area; the number of light-emitting modules 120 and shielding layers 130 is the same as the number of first connection areas, and the light-emitting modules 120, shielding layers 130, and first connection areas are set in a one-to-one correspondence. The design of a single first connection area is suitable for simple display scenarios; the design of at least two first connection areas arranged circumferentially enables the flexible screen component 100 to form multiple independent light-emitting sources to adapt to the multi-area display requirements of the electronic atomizer 10, and the interaction of multiple light sources can achieve richer and more colorful visual effects.

[0080] Please see Figure 1 This application also proposes an electronic atomizer 10, which includes a housing assembly, an electronic control device, and the aforementioned flexible screen assembly 100. The housing assembly includes an inner shell 210 and an outer shell 220, the outer shell 220 being made of a transparent material. The flexible screen assembly 100 is assembled between the inner shell 210 and the outer shell 220, with the flexible screen assembly 100 facing the outer shell 220. The side of the base layer 110 facing away from the light-emitting module 120 and the reflective layer 140 faces the side of the inner shell 210 facing the outer shell 220, and the side of the shielding layer 130 facing away from the light-emitting module 120 and / or the side of the protective layer 160 facing away from the light-guiding layer 150 faces the side of the outer shell 220 facing the inner shell 210. The base layer 110 can be directly connected to the inner shell 210; in embodiments including an adhesive layer, the base layer 110 is bonded to the inner shell 210 through the adhesive layer. In embodiments where the shielding layer 130 is made of foam, the shielding layer 130 is directly connected to the outer shell 220, providing elastic cushioning and enhanced fixation. The protective layer 160 can be directly connected to the outer shell 220; in embodiments including an AF anti-fingerprint film, the protective layer 160 abuts against or adheres to the outer shell 220 through the AF anti-fingerprint film. The electronic control device includes a control chip (not shown), and the connector 122b of the light-emitting module 120 is electrically connected to the control chip. The control chip can control the brightness adjustment, on / off state, and flashing of the LED beads 122.

[0081] The electronic atomizer 10 of this application includes the aforementioned flexible screen assembly 100, and therefore possesses all the beneficial effects of the flexible screen assembly 100, as detailed above. The flexible screen assembly 100 can be mounted on the curved surface area of ​​the housing assembly, enabling a breakthrough in viewing angle, strong adaptability to curved surfaces, and relatively uniform light guidance. Of course, the flexible screen assembly 100 can also be mounted on the planar area of ​​the housing assembly.

[0082] The electronic control device includes a light sensor (not shown), and a control chip electrically connected to the light sensor. The control chip is used to adjust the brightness and / or color of the LED bead 122 in response to the sensing signal from the light sensor. The brightness adjustment range of the LED bead 122 is 50–500 cd / m². 2 The light sensor can collect the ambient light intensity (such as strong outdoor light, weak indoor light, and dim night light) of the environment in which the electronic atomizer 10 is used in real time, and the control chip dynamically adjusts the brightness of the LED beads 122 in response to the sensor signal. In full-color display scenarios, the light sensor can adjust the color saturation of the RGB LED beads 122 in conjunction with the display, such as reducing the proportion of blue in low light to improve visual comfort and solve the problem of traditional fixed-brightness screens being "unclear in strong light and too glaring in low light".
