[0002] With the development of technology, an electronic product that imitates cigarettes has emerged, namely an electronic atomization device.

[0003] As the electronic atomizer device is used, the power supply and the amount of smoke oil in the electronic atomizer device will continue to decrease, which will cause the electronic atomizer device to be unusable.

[0042] The present application is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments use associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and the related operations can be fully understood according to the description in the specification and the general technical knowledge in the art.

[0043] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0044] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0045] In the current technical solution, the display panel of the electronic atomization device is usually based on a PCB board and a digital tube arranged on the PCB board to realize the status information display of the electronic atomization device. However, the thickness of the PCB board is relatively large, and the thickness of the digital tube is also relatively large, so the space occupied by the display panel is relatively large, which is not convenient for the portability of the electronic atomization device.

[0046] In some embodiments of the present application, a flexible display panel is realized based on a flexible mounting layer, a flexible substrate layer, multiple light-emitting devices and a flexible shading layer. Since the flexible display panel is a layered structure composed of various flexible layers, compared with the rigid structure of the PCB board and the digital tube, the overall thickness is greatly reduced. Therefore, the flexible display panel occupies less space, which facilitates the portability of the electronic atomization device.

[0047] In some embodiments, an electronic atomization device is provided, which is used to atomize an atomization matrix to obtain an aerosol. Figure 1 and 2 The electronic atomization device includes a shell, an atomization component, a flexible display panel 100 and a control component, which are described in detail below.

[0048] The shell is used for the installation and fixation of other components, and for storing the atomized matrix. In some embodiments, a storage chamber for storing the atomized matrix is ​​provided inside the shell. For example, the storage chamber can be used to directly store the atomized matrix, or the storage chamber can also be used to install a storage member, and the storage member is used to store the atomized matrix. Among them, the storage member can be a porous material, for example, it can be a liquid storage cotton, and the atomized matrix can be a smoke oil, a liquid medicine, etc. In some embodiments, an air inlet, an atomization channel and an air outlet channel connected to the storage chamber can also be provided in the shell. Among them, the air inlet and the air outlet channel can be respectively arranged at opposite ends of the shell, and the storage chamber can be arranged around the periphery of the atomization channel.

[0049] The atomizing assembly is mounted on the housing to atomize the atomizing matrix to obtain an aerosol, and output it to the outside of the housing through the air outlet channel of the housing. In some embodiments, the atomizing assembly can be arranged in the atomizing channel to atomize the atomizing matrix therein into an aerosol. In some embodiments, the atomizing assembly can atomize the atomizing matrix into an aerosol by heating. In some embodiments, the atomizing matrix in the storage chamber can penetrate into the atomizing assembly so that the atomizing assembly can atomize the atomizing matrix into an aerosol, and the airflow enters the electronic atomizing device from the air inlet of the housing, flows into the atomizing channel, and flows out from the air outlet channel after carrying the aerosol in the atomizing channel.

[0050] The flexible display panel 100 is fixed to the surface of the shell and is used to display the device status of the electronic atomization device. For example, the shell has four sides and two sides at the top and bottom, and the flexible display panel 100 may be fixed to one of the sides. In some embodiments, since the flexible display panel 100 is flexible, it can be bent to a certain extent. Therefore, after the flexible display panel 100 is bent, it can be fixed to multiple sides of the shell, such as any two sides or three sides of the side of the shell, or bent into a ring and fixed to four sides. At this time, at least one side of the shell can be set as a curved surface, so as to facilitate the flexible display panel 100 to be fixed to multiple sides. In some embodiments, after the flexible display panel 100 is bent, it can also be fixed to any two or more sides of the shell, thereby increasing the area of ​​the display area of ​​the flexible display panel 100.

[0051] Please refer to Figure 1 In some embodiments, the flexible display panel 100 includes a flexible mounting layer 10 , a flexible substrate layer 20 , a plurality of light emitting devices 30 and a flexible light shielding layer 40 .

[0052] The flexible mounting layer 10 is fixed to the surface of the housing. For example, one side of the flexible mounting layer 10 is fixed to the surface of the housing, and the other side of the flexible mounting layer 10 is used to fix the flexible substrate layer 20. In some embodiments, the flexible mounting layer 10 is a first adhesive backing, which can be attached to the surface of the housing and the surface of the flexible substrate layer 20, so as to be fixed to the housing and used to fix the flexible substrate layer 20. In this embodiment, the first adhesive backing can be a double-sided adhesive, or a material with stickiness and flexibility such as cured glue, so the first adhesive backing can be bent to a certain extent.

[0053] One side of the flexible substrate layer 20 is fixed to the flexible mounting layer 10, and the other side of the flexible substrate layer 20 is provided with a circuit. In some embodiments, the flexible substrate layer 20 may be a flexible printed circuit (FPC), which is a highly reliable and highly flexible printed circuit board made of polyimide or polyester film as a substrate, and has the characteristics of high wiring density, light weight, thin thickness, and good bendability. Therefore, the flexible circuit board can also be bent to a certain extent, and a circuit is provided thereon to realize a preset circuit function, such as for driving the light-emitting device 30 to emit light.

[0054] Each light emitting device 30 is fixed to the other side of the flexible substrate layer 20 and is electrically connected to the circuit on the flexible substrate layer 20. In some embodiments, the light emitting device 30 is used to emit light when the circuit inputs a driving current thereto, and the magnitude of the driving current can control the brightness of the light emitting device 30. In some embodiments, the light emitting device 30 is an LED chip, and the LED chip is fixed to the flexible substrate layer 20 by die bonding, wherein die bonding is an existing process, that is, the LED chip is bonded to a designated area of ​​the bracket by a colloid (generally a conductive glue or an insulating glue for the LED chip) to form a thermal path or an electrical path, thereby ensuring a stable electrical connection and physical support between the LED chip and the flexible substrate layer 20.

[0055] Please refer to Figure 2In some embodiments, when at least a portion of the flexible display panel 100 is bent in a first direction and then fixed to the surface of the housing, if the first direction is a vertical direction, the length direction of the LED chip on the bent portion of the flexible display panel 100 is a horizontal direction, and if the first direction is a horizontal direction, the length direction of the LED chip on the bent portion of the flexible display panel 100 is a vertical direction. In this embodiment, when the flexible display panel 100 is bent, a certain stress will be generated in the bent portion, and the stress is basically consistent with the bending direction. For example, if the flexible display panel 100 is bent at its left and right ends in a horizontal direction, a corresponding stress will be generated in the bent portion between its left and right ends. Conversely, if the upper and lower ends are bent in a vertical direction, a corresponding stress will be generated in the bent portion between its upper and lower ends. Since the LED chip is not flexible, the LED chip on the bent portion of the flexible display panel 100 needs to bear the stress, which may damage the LED chip. In this regard, in order to reduce the influence of the stress caused by the bending on the LED chip, the length direction of the LED chip on the bent portion of the flexible display panel 100 is perpendicular to the bending direction of the flexible display panel 100, thereby reducing the influence of the stress on the LED chip. For example, when the left and right ends of the flexible display panel 100 are bent in the horizontal direction, the length direction of the LED chip on the flexible display panel 100 at the bent portion between the left and right ends is the vertical direction.

[0056] The flexible light shielding layer 40 is fixed to the other side of the flexible substrate layer 20 and covers a plurality of light emitting devices 30. In some embodiments, the flexible light shielding layer 40 covers a plurality of light emitting devices 30 so that only part of the light can be transmitted, thereby displaying the preset content. For example, the flexible light shielding layer 40 is provided with a plurality of light-transmitting holes of preset shapes, which are used to display the corresponding preset shape information when the light emitting device 30 emits light through, and the combination of the preset shape information displayed between the light-transmitting holes is used to characterize the device state of the electronic atomization device. For example, the light-transmitting hole can be in the shape of a number, so that the corresponding number is displayed when the light emitting device 30 emits light through, and the light-transmitting hole can also be in various shapes such as text shape, letter shape, dot shape, line shape, etc., so as to characterize the device state of the electronic atomization device through the combination of various shape information. In some embodiments, the device state may include an operating mode state, a monitoring parameter state, an alarm state, a charging state, etc. Among them, the operating mode state may include an operating mode of the atomization component, the monitoring parameter state may include the remaining amount of the atomization matrix and the remaining power, the alarm state may include a prompt alarm and a protection alarm, and the charging state may include a full prompt.

[0057] In some embodiments, the flexible light shielding layer 40 includes a second adhesive backing 44 and a flexible light shielding sheet 42. The second adhesive backing 44 is attached to the other side of the flexible substrate layer 20, and the flexible light shielding sheet 42 is attached to the second adhesive backing. In this embodiment, the second adhesive backing 44 can be made of the same material as the first adhesive backing, and the flexible light shielding sheet 42 can be made of a silicone material that can shield light, so the flexible light shielding layer 40 can also be bent to a certain degree.

[0058] The control component is connected to the flexible display panel 100 and the atomization component respectively, so as to control the flexible display panel 100 to display the device state of the electronic atomization device, and to control the atomization component to atomize the atomization matrix. In some embodiments, the control component can be implemented based on a device with a control function such as a single-chip microcomputer and a processor. In some embodiments, the control component can control any light emitting device 30 of the plurality of light emitting devices 30 in the flexible display panel 100 to emit light, and control the atomization component to operate with preset parameters.

[0059] Please refer to Figure 1 In some embodiments, in order to realize the color light emission of the flexible display panel 100, the flexible display panel 100 further includes a flexible color film layer 50 fixed to the flexible light shielding layer 40, and the flexible color film layer 50 has a color area with a shape and position corresponding to each light-transmitting hole of the flexible light shielding layer 40, and the color area is used to display a preset color when the light-emitting device 30 emits light through. In some embodiments, the flexible color film layer 50 is based on the principle of three primary colors, and filters the light of unnecessary colors in the white light, so that the light of the required color is emitted. At this time, the light-emitting device 30 is used to emit white light, for example, a blue LED chip is used, and then the blue light can emit white light through the phosphor. In some embodiments, the flexible color film layer 50 includes a PET (polyethylene terephthalate) material layer, which is configured with a film for filtering and forming a color area. In some embodiments, the flexible color film layer 50 also includes a diffusion film fixed to the PET material layer, and the diffusion film is used to correct the light into a uniform surface light source to achieve the effect of optical diffusion, thereby achieving a better display effect. Therefore, the flexible color film layer 50 can also be bent to a certain extent.

[0060] In some embodiments, in order to realize the color light emission of the flexible display panel 100, the light emitting device 30 may be configured to emit at least one of red light, blue light and green light, and the control component is used to control the light emitting device 30 to emit light of a preset color based on at least one of red light, blue light and green light. For example, the light emitting device 30 may include a blue LED chip, a red LED chip and a green LED chip, so that based on the principle of three primary colors, light of a preset color can be emitted.

[0061] The above is some description of the electronic atomization device.

[0062] Some embodiments provide a flexible display panel that can be fixed to a surface of an electronic atomization device to display the device status of the electronic atomization device.

[0063] In some embodiments, the flexible display panel includes a flexible substrate layer 20, a plurality of light emitting devices 30 and a flexible light shielding layer 40. The flexible substrate layer 20, the light emitting devices 30 and the flexible light shielding layer 40 may adopt the structures and materials in the above embodiments, which will not be described in detail.

[0064] In some embodiments, the flexible display panel may further include a flexible color film layer 50 and a flexible mounting layer 10. The flexible color film layer 50 may adopt the structure and material in the above embodiment to emit light of a preset color. The flexible mounting layer 10 may adopt the structure and material in the above embodiment to be fixed to the surface of the electronic atomization device, which will not be described in detail here.

[0065] The above specific examples are used to illustrate the present application, which is only used to help understand the present application and is not intended to limit the present application. For technicians in the technical field to which the present application belongs, they can also make some simple deductions, deformations or substitutions based on the ideas of the present application.
