[0043] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of some inventions, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0044] See also Figures 1 to 4 The present invention provides an electronic cigarette capable of 3D display, including a shell 100, an atomization structure 200, a mouthpiece 300, a control panel 400, a 3D display structure 500 and a housing 600.

[0045] The atomization structure 200 is disposed in the housing 100, and the mouthpiece 300 is disposed on the housing 100 and communicated with the atomization structure 200. The control board 400 is disposed in the housing 100 and connected with the atomization structure 200. Specifically, the control board 400 can control the atomization structure 200 to work, and the atomization structure 200 generates smoke that is inhaled by the user through the mouthpiece 300.

[0046] It should be noted that the atomization structure 200 can adopt existing technology. For example, the heating wire of the atomization structure 200 can heat the tobacco oil in the atomization structure 200 through the control of the control board 400, thereby atomizing the tobacco oil to produce smoke. The smoke flows through the smoke duct of the atomization structure 200 to the mouthpiece 300 to be inhaled by the user.

[0047] The 3D display structure 500 is disposed on the housing 100, and the 3D display structure 500 is connected to the control board 400. Specifically, the control board 400 controls the 3D display structure 500 to work, thereby displaying a 3D effect.

[0048] The housing 600 is disposed on the housing 100 , and the 3D display structure 500 is located between the housing 600 and the housing 100 , and at least the area of ​​the housing 600 corresponding to the 3D display structure 500 is light-transmissive.

[0049] Specifically, when the 3D display structure 500 displays a 3D effect under the control of the control board 400, the 3D display effect can be observed through the housing 600. In some embodiments, the housing 600 can cooperate with the housing 100 to fix the 3D display structure 500, and on the other hand, the housing 600 can protect the 3D display structure 500.

[0050] Since at least the area of ​​the housing 600 corresponding to the 3D display structure 500 is light-transmissive, the user can observe the 3D pattern displayed by the 3D display structure 500 through the housing 600 .

[0051] That is, in the electronic cigarette of the present application, by setting the 3D display structure 500 on the shell 100, and setting the shell 600 on the shell 100 to protect the 3D display structure 500, the 3D display structure 500 is controlled by the control board 400 to display a 3D effect pattern. Since the shell 600 is light-transmissive, the user can observe the 3D effect pattern displayed by the 3D display structure 500 through the shell 600. This method can display a 3D pattern on the shell 100 of the electronic cigarette.

[0052] Furthermore, in order to facilitate the arrangement of the 3D display structure 500 on the shell 100 , the electronic cigarette may further include a support 700 , which is arranged on the shell 100 , the 3D display structure 500 is arranged on the support 700 , and the 3D display structure 500 is located between the support 700 and the shell 600 .

[0053] For example, the 3D display structure 500 may be first disposed on the support member 700, and then the support member 700 may be disposed on the housing 100. In some embodiments, after the support member 700 is disposed on the housing 100, the housing 600 may be disposed on the housing 100, so that the support member 700 and the 3D display structure 500 mounted on the support member 700 are wrapped by the housing 600 to achieve assembly. In other embodiments, after the support member 700 is disposed on the housing 100, the housing 600 may be disposed on the support member 700, and the housing 600 is indirectly disposed on the housing 100 through the support member 700.

[0054] Further, the support member 700 may be provided with an assembly groove 710, and the 3D display structure 500 is arranged in the assembly groove 710. It can be understood that the assembly groove 710 can be used to install and position the 3D display structure 500, which is convenient for the installation of the 3D display structure 500, and under the action of the assembly groove 710, the support member 700 cooperates with the housing 600 to achieve the clamping and fixing of the 3D display structure 500.

[0055] See also Figure 4 In some embodiments, in order to further enhance the 3D display effect of the 3D display structure 500 , the 3D display structure 500 is made of a flexible material so that the 3D display structure 500 can be bent.

[0056] For example, the 3D display structure 500 is bent on the housing 100. It can be understood that the 3D display structure 500 can enhance the visual effect of the 3D display after being bent.

[0057] Specifically, the housing 100 may include a first side surface and a second side surface and a third side surface respectively adjacent to the first side surface, the 3D display structure 500 is disposed on the first side surface of the housing 100, and the 3D display structure 500 extends the second side surface and / or the third side surface. In other words, the 3D display structure 500 is at least located on two adjacent side surfaces of the housing 100.

[0058] In the first embodiment, the 3D display structure 500 may be disposed on the first side surface and the second side surface, and the 3D display structure 500 may have a bending surface (or a curved surface) formed at least between the first side surface and the second side surface.

[0059] In the second embodiment, the 3D display structure 500 may be disposed on the first side surface and the third side surface, and the 3D display structure 500 may have a bending surface (or a curved surface) formed at least between the second side surface and the third side surface.

[0060] In a third embodiment, the 3D display structure 500 can be arranged on a first side surface, a second side surface and a third side surface (not shown in the figure), and the 3D display structure 500 has a bending surface (or arc surface) formed at least between the first side surface and the second side surface, and between the second side surface and the third side surface.

[0061] Of course, in order to display a better 3D visual effect, the first side surface may also be set to be a curved surface, so that the 3D display structure 500 located on the second side surface may present a curved surface as a whole.

[0062] In addition, in order to better support the 3D display structure 500 after being bent, the outer shape of the support member 700 can be set to be consistent with the shape of the 3D display structure 500 after being bent to ensure that the 3D display structure 500 can fit the support member 700.

[0063] In addition, in order to allow the housing 600 to completely protect the folded 3D display structure 500 , the outer shape of the housing 600 may be configured to be consistent with the shape of the folded 3D display structure 500 to ensure that the 3D display structure 500 can be completely covered by the housing 600 .

[0064] See also Figure 4 , the housing 100 may also be provided with a first receiving groove 110, and the outer shell 600 is provided in the first receiving groove 110. It can be understood that, since the 3D display structure 500 is located between the outer shell 600 and the housing 100, when the outer shell 600 is provided in the first receiving groove 110, the 3D display structure 500 is correspondingly located in the first receiving groove 110, and the first receiving groove 110 can provide installation space for the 3D display structure 500 and the outer shell 600, so as to prevent the 3D display structure 500 and the outer shell 600 from protruding from the housing 100, thereby improving the integrity of the electronic cigarette.

[0065] Further, a second accommodating groove 120 may be provided in the first accommodating groove 110, and the supporting member 700 is provided in the second accommodating groove 120. It can be understood that the second accommodating groove 120 can provide an installation space for the supporting member 700, and when the 3D display structure 500 is provided on the supporting member 700, the supporting member 700 can be provided in the second accommodating groove 120, and then the housing 600 is provided in the first accommodating groove 110 to form a complete whole with the housing 100.

[0066] See also Figures 4 to 6 The 3D display structure 500 may include a grating plate 510 , a bottom plate 520 , a plurality of light emitting members 530 and a light guide plate 540 .

[0067] Among them, a pattern is arranged on the grating plate 510. It can be understood that after the pattern is arranged on the grating plate 510, a 3D pattern display effect can be achieved under the action of light. This structure is a common prior art and will not be described in detail here.

[0068] The bottom plate 520 is disposed on the housing 100, and a plurality of light emitting elements 530 are respectively disposed on the bottom plate 520 in the area near the edge, and the light emitting elements 530 are connected to the control board 400. The grating plate 510 is disposed on the bottom plate 520 and is connected to the edge of the grating plate 510 through the edge of the bottom plate 520. The light guide plate 540 is disposed between the grating plate 510 and the bottom plate 520, and is used to guide light to the light emitting elements 530, and the light guide plate 540 is attached to the grating plate 510.

[0069] For example, the edge of the light guide plate 540 may cover the light emitting element 530 , or the light guide plate 540 may be in contact with the light emitting element 530 , so that the light emitting element 530 may emit light to make the entire light guide plate 540 emit light.

[0070] In addition, when the electronic cigarette includes a support member 700 , the bottom plate 520 may be disposed on the support member 700 , for example, located in the assembly groove 710 of the support member 700 .

[0071] Specifically, after the light-emitting element 530 on the base plate 520 emits light, the light guide plate 540 located between the base plate 520 and the grating plate 510 guides the light emitted by the light-emitting element 530. Since the light guide plate 540 is attached to the grating plate 510, the light guide plate 540 can become the backlight source of the grating plate 510, making the entire grating plate 510 brighter, and then making the pattern bright, producing a better 3D effect.

[0072] In addition, after the edge of the bottom plate 520 is connected to the edge of the grating plate 510, the bottom plate 520 and the grating plate 510 can be formed into a whole, and the light-emitting component 530 and the light guide plate 540 can be encapsulated between the bottom plate 520 and the grating plate 510. Moreover, since the bottom plate 520 and the grating plate 510 are connected by the edge, this will not affect the setting of the light guide plate 540 between the bottom plate 520 and the grating plate 510 and the light guiding function.

[0073] In the above-mentioned 3D display structure 500, a grating plate 510 is arranged on the bottom plate 520, and a light-emitting member 530 is arranged at the edge of the bottom plate 520. The light-emitting member 530 is located at the edge to avoid affecting the connection between the bottom plate 520 and the grating plate 510. A light guide plate 540 is arranged between the grating plate 510 and the bottom plate 520. The light guide plate 540 is in contact with the grating plate 510. The light guide plate 540 is used to guide light to the light-emitting member 530, so as to guide the light generated by the light-emitting member 530 located at the edge to the back of the entire grating plate 510. In this way, the entire grating plate 510 can be illuminated, and then the pattern on the grating plate 510 can have a clearer three-dimensional sense under the light of the lamp, and the three-dimensional sense will not be affected by the external dark light environment. At the same time, the user can also feel the depth and three-dimensional sense when the distance between the user and the grating plate 510 is far.

[0074] Furthermore, the 3D display structure 500 may also include a flexible circuit board 550, which is disposed on the bottom plate 520, connected to the control board 400, and the light-emitting element 530 is disposed on the flexible circuit board 550. It can be understood that by disposing a plurality of light-emitting elements 530 on the flexible circuit board 550, it is convenient to simultaneously control the operation of the plurality of light-emitting elements 530. In addition, the flexible circuit board 550 is a flexible structure, thin in thickness, and small in area, which can reduce the influence of the connection between the grating plate 510 and the bottom plate 520, and avoid occupying too large an area of ​​the bottom plate 520 to affect the pattern display of the light guide plate 540.

[0075] Preferably, the flexible circuit board 550 may be disposed close to the edge of the bottom plate 520 to avoid affecting the display of the grating plate 510 .

[0076] For details, see Figure 5 and 6 In some embodiments, in order to ensure that the grating plate 510 has a backlight with sufficient brightness and prevent the light-emitting element 530 from affecting the grating plate 510, the bottom plate 520 may include a first edge and a second edge that are relatively arranged, and a plurality of light-emitting elements 530 are arranged near the first edge and the second edge along the length direction of the edge.

[0077] Further, in order to facilitate the simultaneous control of the light emitting member 530 located at the first edge and the second edge, and to prevent the flexible circuit board 550 from affecting the connection between the bottom plate 520 and the grating plate 510, the flexible circuit board 550 may further include a first circuit board portion 551, a second circuit board portion 552, a third circuit board portion 553, and a fourth circuit board portion 554. The first circuit board portion 551 is arranged at the first edge, the second circuit board portion 552 is arranged at the second edge, and the light emitting member 530 is arranged on the first circuit board portion 551 and the second circuit board portion 552, respectively. The third circuit board portion 553 is arranged on the third edge adjacent to the first edge and the second edge of the bottom plate 520, and is connected to the first circuit board portion 551 and the second circuit board portion 552, respectively. The fourth circuit board portion 554 is connected to one of the first circuit board portion 551, the second circuit board portion 552, or the third circuit board portion 553, and the fourth circuit board portion 554 is connected to the control board 400.

[0078] See also Figure 5 , the 3D display structure 500 further includes a light shielding ring 560, which is disposed between the grating plate 510 and the bottom plate 520 and is located outside the light emitting element 530, and the light guide plate 540 is located inside the light shielding ring 560. It can be understood that the light shielding ring 560 located between the grating plate 510 and the bottom plate 520 can prevent the light of the light emitting element 530 and the light guide plate 540 from leaking from between the grating plate 510 and the bottom plate 520, and plays a role in preventing light leakage between the grating plate 510 and the bottom plate 520.

[0079] In some embodiments, the shading ring 560 can be a shading cotton. When the base plate 520 is connected to the grating plate 510, the shading ring 560 is clamped between the base plate 520 and the grating plate 510, thereby shading the connection between the base plate 520 and the grating plate 510.

[0080] See also Figure 5In some embodiments, the 3D display structure 500 may further include a light-transmitting member 570 , which is disposed between the light guide plate 540 and the grating plate 510 and adheres to each other, and only the area of ​​the light-transmitting member 570 corresponding to the pattern on the grating plate 510 is transparent.

[0081] It can be understood that after the light guide plate 540 guides light, the entire light guide plate 540 can emit light. After the entire light guide plate 540 emits light, the entire grating plate 510 will become brighter, so that both the patterned area and the non-patterned area of ​​the grating plate 510 will emit light, which will affect the three-dimensional sense and depth sense of the pattern felt by the user and affect the viewing effect. Therefore, by arranging a light-transmitting member 570 between the light guide plate 540 and the grating plate 510, and allowing only the area corresponding to the pattern on the light-transmitting member 570 to transmit light, only the area with the pattern on the grating plate 510 can emit light, thereby improving the 3D display visual effect.

[0082] Furthermore, in some embodiments, in order to facilitate the connection between the bottom plate 520 and the grating plate 510, the edge of the bottom plate 520 and the edge of the grating plate 510 may be connected by an adhesive (not shown in the figure), for example, by adhesive tape, double-sided tape, etc.

[0083] Furthermore, in some embodiments, at least the surface of the bottom plate 520 close to the grating plate 510 can reflect light, and the bottom plate 520 can be made of a reflective material. Specifically, when the light-emitting element 530 and the light guide plate 540 emit light, the bottom plate 520 can reflect the light to one side of the grating plate 510, so that the light received by the grating plate 510 is more uniform and brighter, thereby improving the effect of 3D display.

[0084] In other embodiments, at least one side of the bottom plate 520 close to the grating plate 510 may be provided with a reflective film.

[0085] Furthermore, in some embodiments, the grating plate 510, the bottom plate 520 and the light guide plate 540 can all be made of flexible materials. It is understood that the grating plate 510, the bottom plate 520 and the light guide plate 540 made of flexible materials can be bent, which can make the application scenarios of the 3D display structure 500 more diverse, and when the grating plate 510 is bent, the 3D display effect of the pattern on the grating plate 510 is more realistic.

[0086] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of some inventions should be included in the protection scope of some inventions.
