For example, some electronic cigarettes are equipped with screens to display interesting patterns.

[0003] Currently, most of the electronic cigarettes on the market have a flat screen installed on the electronic cigarette, and there are few electronic cigarette products with screens installed on curved surfaces. This is because the existing screens cannot be bent and therefore cannot be installed in a consistent manner on electronic cigarette products with curved surfaces. Utility Model Content

[0009] Optionally, the flexible screen structure further includes a shading pad, which surrounds one or more positive-light-emitting LEDs, and opposite sides of the shading pad are seamlessly connected to the flexible substrate and the light-guiding film, respectively.

[0010] Optionally, the light shielding strip and the light shielding pad are both higher than the light emitting module.

[0011] Optionally, the thickness of the light-guiding film is 0.6-2 mm.

[0012] The utility model also provides an electronic cigarette, comprising the flexible screen structure as described above, wherein the electronic cigarette further comprises an electronic cigarette shell, wherein the flexible screen structure is installed on at least two surfaces of the electronic cigarette shell, and the at least two surfaces are not in the same plane.

[0013] Optionally, the electronic cigarette shell includes a window, which is used to install the flexible screen structure, and the window extends from the front side of the electronic cigarette shell along the circumference of the electronic cigarette shell to the rear side of the electronic cigarette shell, the side-emitting LED is located on the front side and the rear side, and the positive-emitting LED is located between the side-emitting LED on the front side and the side-emitting LED on the rear side.

[0015] Compared with the prior art, the flexible screen structure and the electronic cigarette provided by the embodiment of the utility model have the following advantages:

[0016] 1. When the flexible substrate is powered on, the LED on the flexible substrate is lit, and the phosphor layer on the inner side of the light guide film refracts the light of the LED onto the pattern layer on the outer side of the light guide film, so that the pattern on the entire flexible screen can be lit;

[0017] 2. The light of the side-emitting LED is refracted by the phosphor layer and emitted from the side end of the light guide film to the side of the pattern in the pattern layer. The light of the positive-emitting LED is refracted by the phosphor layer and emitted to the pattern in the pattern layer toward the side of the light guide film. The coordination of the two refracted lights of the side-emitting LED and the positive-emitting LED makes the light distribution on the pattern more uniform.

[0035] First embodiment

[0036] Please refer to Figure 1 and Figure 2 In an embodiment of the utility model, a flexible screen structure is provided, including a flexible substrate 1, a light emitting module 2, a shading strip 3, a light guide film 4, a phosphor layer 5 and a pattern layer 6, wherein the light emitting module 2 and the shading strip 3 are jointly arranged on one side surface of the flexible substrate 1, and the phosphor layer 5 and the pattern layer 6 are respectively arranged on two opposite side surfaces of the light guide film 4.

[0037] Please refer to Figure 1Specifically, the light emitting module 2 is a component that displays a pattern by emitting light. The light emitting module can be a whole flexible display screen, or an LED, or an LED dot matrix composed of multiple LEDs. In the first embodiment, the light emitting module 2 adopts an LED dot matrix, and the LED dot matrix is ​​composed of multiple positive-emitting LEDs 21 and multiple side-emitting LEDs 22, wherein the side-emitting LEDs 22 are arranged at the edge of the flexible screen structure, and the position of the positive-emitting LEDs 21 is closer to the center of the flexible screen structure than the side-emitting LEDs 22, and both the positive-emitting LEDs 21 and the side-emitting LEDs 22 are electrically connected to the flexible substrate 1.

[0038] Please refer to Figure 1 , the flexible substrate 1 is parallel to and opposite to the light guide film 4, and the edge of the flexible substrate 1 is also aligned with the edge of the light guide film 4; there is a gap between the flexible substrate 1 and the light guide film 4, and the LED dot matrix and the shading strip 3 are arranged in the gap, and the shading strip 3 is arranged along the edge of the gap (see Figure 2 ), and the side of the shading strip 3 facing the light guide film 4 is seamlessly connected to the inner side of the light guide film 4 (that is, the side of the light guide film 4 facing the gap), and the side of the shading strip 3 facing the flexible substrate 1 is seamlessly connected to the inner side of the flexible substrate 1 (that is, the side of the flexible substrate 1 facing the gap), and the function of the shading strip 3 is to close the edge of the gap.

[0039] Please refer to Figure 1 , the shading strip 3 is used to block the light of the LED dot matrix and prevent the light from emitting from the edge of the gap between the light guide film 4 and the flexible substrate 1. Exemplarily, the shading strip 3 can be made of any opaque material, such as a foam block or foam. In the first embodiment, the shading strip 3 is made of foam, and the height of the shading strip 3 is higher than the LED dot matrix 2, that is, the shading strip 3 keeps a certain distance between the inner side of the light guide film 4 and the top of the LED dot matrix 2; because the foam is compressible, the foam has a buffering function after the light guide film 4 is compressed; because the foam is bendable, the shading strip 3 can bend with the flexible substrate 1 and the light guide film 4.

[0040] The flexible screen structure can be used alone or in combination with other devices, such as an electronic cigarette; specifically, the flexible screen structure is detachably arranged on the surface of the electronic cigarette for use through a first detachable connection structure. Exemplarily, the first detachable connection structure can adopt a snap-on structure, that is, a part of the snap-on structure is arranged on the installation side of the flexible substrate 1, and the rest of the snap-on structure is arranged on the surface of the electronic cigarette, and the flexible screen structure is installed on the surface of the electronic cigarette by connecting the parts of the snap-on structure, and the snap-on structure is detachable to replace the flexible screen structure; the first detachable connection structure can also adopt an adhesive structure, for example, a back glue is arranged on the installation side of the flexible substrate 1, and the flexible substrate 1 is attached to the surface of the electronic cigarette by the back glue, and the flexible screen structure can be easily removed and replaced by heating the back glue with a hot air gun; the first detachable connection structure can also adopt a magnetic attraction structure, that is, a first magnetic block is fixed on the installation side of the flexible substrate 1, and a second magnetic block is fixed on the surface of the electronic cigarette, and the flexible screen structure is installed on the surface of the electronic cigarette by the attraction between the first magnetic block and the second magnetic block, and the first magnetic block and the second magnetic block can be separated to replace the flexible screen structure.

[0041] Exemplarily, the installation side of the first detachable connection structure on the flexible substrate 1 can be an edge of the flexible substrate 1 or a side of the flexible substrate 1 facing away from the light guide film 4. In the first embodiment, the first detachable connection uses adhesive backing, and the installation side of the adhesive backing is the side of the flexible substrate 1 facing away from the light guide film 4.

[0042] Please refer to Figure 1 In addition to replacing the flexible screen structure as a whole, a lower-cost replacement method can also be used: only replace the light-guiding film 4 (replace the phosphor layer 5 and the pattern layer 6 on both sides of the light-guiding film 4 together). A second detachable connection structure is provided between the light-guiding film 4 and the flexible substrate 1. Exemplarily, the second detachable connection structure may adopt a snap-on structure, an adhesive structure, or a magnetic structure. In the first embodiment, the second detachable connection structure adopts a backing adhesive as an adhesive structure, and the backing adhesive is pasted on opposite sides of the shading strip 3. The shading strip 3 is seamlessly bonded to the inner side of the light-guiding film 4 through the backing adhesive on one side, and the shading strip 3 is seamlessly bonded to the flexible substrate 1 through the backing adhesive on the other side, thereby achieving the shading strip 3 closing the gap edge between the flexible substrate 1 and the light-guiding film 4.

[0043] Please refer to Figure 1The light-guiding film 4 is a transparent film, and the inner side of the light-guiding film 4 is provided with the above-mentioned phosphor layer 5, which is a thin layer painted on the inner side of the light-guiding film 4; the outer side of the light-guiding film 4 is provided with the above-mentioned pattern layer 6, which is a transparent plate, and the transparent plate has a pattern locally; the thickness of the light-guiding film 4 is determined by the light display effect of the pattern on the pattern layer 6, and the thickness of the light-guiding film 4 ranges from 0.6 to 2 mm according to the pattern on the pattern layer 6 or the thickness of the pattern layer 6. Both the pattern layer 6 and the light-guiding film 4 have the bendability of the flexible substrate 1, so the pattern layer 6 and the light-guiding film 4 are made of tough and bendable materials. Exemplarily, the light-guiding film 4 and the pattern layer 6 are both made of PC material plates. When the flexible substrate 1 is powered on, the side-emitting LED 22 and the front-emitting LED 21 on the flexible substrate 1 are lit at the same time, irradiating the light onto the light-guiding film 4. The phosphor layer 5 on the inner side of the light-guiding film 4 refracts the light onto the pattern layer 6, so that the pattern on the entire screen can be lit.

[0044] Please refer to Figure 1 and Figure 2 The side-emitting LED 22 is located at the edge of the flexible substrate 1 and is electrically connected to the inner side of the flexible substrate 1, and the side-emitting LED 22 is located next to the shading strip 3; there are multiple side-emitting LEDs 22, and all the side-emitting LEDs 22 are spaced apart along the length direction of the two opposite sides of the flexible substrate 1.

[0045] Please refer to Figure 1 and Figure 2 , the positive emitting LED 21 is facing the pattern on the pattern layer 6; there are multiple positive emitting LEDs 21, which can be distributed regularly or irregularly, and the distribution of the positive emitting LEDs 21 depends on the pattern to be expressed.

[0046] The luminous intensity of the side-emitting LED 22 is greater than that of the front-emitting LED 21. For example, this can be achieved by supplying a larger current to the side-emitting LED 22 or increasing the size of the side-emitting LED 22. In the first embodiment, the input current of the side-emitting LED 22 is the same as that of the front-emitting LED 21, but the size of the side-emitting LED 22 is larger than that of the front-emitting LED 21, that is, the lamp beads of the side-emitting LED 22 are larger, and the luminous area is larger, so more light is emitted. The purpose is to solve the following problem: the front-emitting LED rectangle composed of the front-emitting LED 21 is easy to illuminate small bright spots one by one on the pattern layer 6, and the light looks uneven (the effect to be achieved should be that the brightness everywhere is roughly consistent or the overall transition is soft). If the side-emitting LED 22 emits more light, part of the light is used to illuminate most of the side-emitting area on the pattern layer 6 (that is, the area corresponding to the side-emitting LED 22 on the pattern layer 6), and part of the light will be emitted to the front-emitting area (that is, the area corresponding to the front-emitting LED 21 on the pattern layer 6). While improving the brightness of the pattern layer 6, small bright spots on the pattern layer 6 can be avoided.

[0047] Please refer to Figure 1 , illustratively, the flexible substrate 1 can be any flexible and bendable substrate; in the first embodiment, the flexible substrate 1 is an FPC substrate. Since the flexible substrate 1, the light guide film 4, the pattern layer 6 and the light shielding strip 3 can be bent together, the flexible screen proposed in this embodiment can be mounted on the curved surfaces of various devices in a consistent manner; by providing a backing adhesive layer 8 on the outer surface of the flexible substrate 1, the bent flexible substrate 1 can be attached to the curved surfaces of various devices.

[0048] The flexible screen structure provided by the embodiment of the utility model has the advantages that: when the flexible substrate 1 is powered on, the LED on the flexible substrate 1 is lit, and the phosphor layer 5 on the inner side of the light guide film 4 refracts the light of the LED to the pattern layer 6 on the outer side of the light guide film 4, so that the pattern on the entire flexible screen can be lit; the light of the side-emitting LED 22 is refracted by the phosphor layer 5 and emitted from the side end of the light guide film 4 to the side of the pattern in the pattern layer 6, and the light of the positive-emitting LED 21 is refracted by the phosphor layer 5 and emitted to the pattern in the pattern layer 6 toward one side of the light guide film 4. The cooperation of the two refracted lights of the side-emitting LED 22 and the positive-emitting LED 21 makes the light distribution on the pattern more uniform.

[0049] Second embodiment

[0050] Please refer to Figure 3 This embodiment provides another flexible screen structure based on the first embodiment. Compared with the flexible screen structure of the first embodiment, a shading pad 7 is added.

[0051] Please refer to Figure 3The light shielding pad 7 is arranged in a circle shape to surround the positive light emitting LED 21, and is used to isolate adjacent positive light emitting LEDs 21 that emit different colored lights, so as to prevent the different colored lights emitted by adjacent positive light emitting LEDs 21 from crossing colors on the pattern. The light shielding pad 7 is at the same height as the light shielding strip 3, and is also higher than the LED dot matrix. The opposite sides of the light shielding pad 7 are seamlessly bonded to the inner side of the flexible substrate 1 and the inner side of the light guide film 4 by using adhesive. Exemplarily, the light shielding pad 7 is made of foam.

[0052] Third embodiment

The shape of the screen lens 14 is similar to the missing part of the electronic cigarette housing 10 at the window 106. The inner cavity surrounded by the screen lens 14 and the electronic cigarette housing 10 accommodates the above-mentioned flexible screen structure, the control panel 11, the oil cup 12 and the bracket 13.

[0054] Please refer to Figure 4 A button 19 is arranged on the side of the electronic cigarette shell 10, and the button 19 is electrically connected to the control board 11. Pressing the button 19 can energize the flexible substrate 1 of the flexible screen structure through the control board 11, so that the pattern layer 6 of the flexible screen structure emits light; in addition, a sensor, such as a smoke flow sensor, can be arranged in the suction nozzle 9, and the sensor is electrically connected to the control board 11, so that the sensor can be triggered during inhalation, and the sensor feeds back an electrical signal to the control board 11, and the control board 11 controls the light-emitting function of the flexible screen structure.

[0055] Please refer to Figure 6 , a flat cable 17 is arranged at the bottom of the flexible substrate 1 of the flexible screen structure, the control board 11 is located at the bottom of the electronic cigarette housing 10, and the flexible substrate 1 is electrically connected to the control board 11 through the flat cable 17.

When the flexible screen structure is inserted into the inner side of the positioning block 15 for installation, the guide block 16 guides the flexible screen structure.

[0056] Exemplarily, the flexible screen structure can be mounted on the surface of the electronic cigarette housing 10, or mounted on the surface of the bracket 13 and / or the surface of the oil cup 12. In the third embodiment, the flexible substrate 1 of the flexible screen structure is attached to the surface of the bracket 13 and / or the surface of the oil cup 12 by adhesive.

[0057] Please refer to Figure 4 and Figure 5 , the window 106 passes through the front and rear opposite sides of the electronic cigarette housing 10, and the window 106 extends from the front side of the electronic cigarette housing 10 along the circumference of the electronic cigarette housing 10 to the rear side of the electronic cigarette housing 10. The screen lens 14 is located opposite to and covers the pattern layer 6 of the flexible screen structure. The screen lens 14 is formed in one piece by the front lens 14a, the rear lens 14b and the arc lens 14c, wherein the arc lens 14c is a transition connection between the front lens 14a and the rear lens 14b; the outermost pattern layer 6 of the flexible screen structure is at a certain distance from the inner side of the screen lens 14; the periphery of the screen lens 14 is connected to the periphery of the window 106, which has a dustproof effect and can keep the flexible screen structure inside the screen lens 14 clean.

[0058] Please refer to Figure 5 and Figure 7 , the screen lens 14 is detachably connected to the electronic cigarette housing 10. Exemplarily, the detachable connection method is one of magnetic connection, snap connection or adhesive connection. In the third embodiment, the screen lens 14 is connected to the electronic cigarette housing 10 by snap connection. The snap includes a first card block 141, a first card slot 101, a second card block 103 and a second card slot 142. The first card block 141 is arranged on the side end of the screen lens 14 along the width direction of the electronic cigarette. The first card slot 101 is arranged on the electronic cigarette housing 10 and its position corresponds to the first card block 141; please refer to Figure 5 The electronic cigarette housing 10 is provided with a step 102 extending into the window 106, and the step 102 supports the lower surface of the screen lens 14, that is, the lower surface of the screen lens 14 is attached to the upper surface of the step 102, and the second block 103 is integrally formed on the step 102, please refer to Figure 8 The second card slot 142 is disposed on the lower surface of the screen lens 14 and its position corresponds to the second card block 103 .

[0059] Please refer to Figure 5 , Figure 7 and Figure 8When the screen lens 14 is installed into the window 106 along the width direction of the electronic cigarette shell 10, the first card block 141 is snapped into the first card slot 101, and the second card block 103 is snapped into the second card slot 142; this embodiment does not limit the specific positions of the components of the buckle. For example, the first card block 141 can also be set on the electronic cigarette shell 10, and the first card slot 101 can also be set on the screen lens 14. It is only necessary to satisfy that the first card block 141 and the first card slot 101 are located on two different components and can be snapped together. The positions of the second card block 103 and the second card slot 142 are similar.

[0060] Please refer to Figure 7 and Figure 8 There is also a limiting structure between the electronic cigarette housing 10 and the screen lens 14 to prevent the screen lens 14 from shaking in the window 106: the third clamping block 104 and the third clamping slot 143. The third clamping slot 143 is set at the upper and lower ends of the arc lens 14c along the height direction of the electronic cigarette. The third clamping block 104 is set on the electronic cigarette housing 10 and its position corresponds to the third clamping slot 143. The third clamping slot 143 is surrounded by the L-shaped frame 18 and the inner wall of the screen lens 14. When the screen lens 14 is installed in the window 106, the end of the L-shaped frame 18 away from the inner wall of the screen lens 14 abuts against the outer wall of the third clamping block 104 and is slightly deformed. As the screen lens 14 moves into the window 106, the L-shaped frame 18 is squeezed and avoids the third clamping block 104, and the third clamping block 104 is squeezed into the third clamping slot 143. The electronic cigarette shell 10 is formed by splicing a front shell 10a and a rear shell 10b. The third clamping block 104 is only arranged on the front shell 10a or the rear shell 10b. The splicing seam between the front shell 10a and the rear shell 10b is aligned with the middle section of the third clamping groove 143. This design facilitates the quick disassembly of the front shell 10a or the rear shell 10b where the third clamping block 104 is not arranged.

[0061] Please refer to Figure 5 and Figure 8 When the screen lens 14 needs to be removed, first disassemble the connection structure between the front shell 10a and the rear shell 10b, then press the edge of the window 106 of the half of the electronic cigarette shell 10 (for example, the front shell 10a) where the third block 104 is not provided, so that the second block 103 next to the pressing position is disengaged from the second slot 142, and then push the front shell 10a in the direction away from the screen lens 14, so that the first block 141 can be disengaged from the first slot 101 next to the pressing position (see Figure 7 ) to disengage the front housing 10a; please refer to Figure 7 and Figure 8, and then press the edge of the window 106 of the rear housing 10b to disengage the second block 103 of the rear housing 10b from the second slot 142 on the other side of the screen lens 14, and then push the screen lens 14 along the arc surface of the arc lens 14c to move the third block 104 and the third slot 143 relative to each other and separate, and at this time, the first block 141 on the other side of the screen lens 14 is also separated from the first slot 101 of the rear housing 10b, and the screen lens 14 is now separated from the rear housing 10b. When the screen lens 14 needs to be installed, the above process can be reversed.

[0062] Please refer to Figure 4 The screen lens 14 is provided with a first chamfer 144 at the periphery facing outward, and the electronic cigarette housing 10 is provided with a second chamfer 105 at the periphery of the window 106 facing outward. The first chamfer 144 and the second chamfer 105 form a groove. When removing the screen lens 14, fingers can be pressed in the groove to facilitate pushing the screen lens 14.
