[0002] In the field of electronic devices, especially in the application of digital display screens with gold finger interfaces, external gold finger digital display screens are widely used because they are convenient to connect and disassemble with devices. A gold finger is a connector composed of multiple golden conductive contacts. These contacts are evenly distributed on a narrow plastic strip and are precisely arranged on the edge of a printed circuit board (PCB). When the gold finger is inserted into a matching slot, each contact is connected to the corresponding solder joint on the main board, thus securely fixing the digital display screen and ensuring that electrical signals and power can be effectively transmitted between the main control circuit board and the digital display screen.

[0003] In electronic cigarette devices, digital display screens are increasingly widely used to display key information such as battery level, temperature control, and usage time. These digital display screens are usually connected to the main control circuit board of the electronic cigarette through external gold fingers to achieve signal transmission and power supply. Currently, digital display screens generally include a sheet-shaped display screen plastic housing, a printed circuit board, and multiple LED chips.

[0034] The following will, with reference to the accompanying drawings, elaborate on some embodiments of the present application. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0035] According to Figures 1-5 , in the embodiments of the present application, an externally-connected gold finger digital display screen 100 based on LED chips is provided, which includes a housing 10, a digital display screen 20 and a wiring layer 40.

[0036] Among them, the digital display screen 20 is arranged inside the cavity of the housing 10. The digital display screen 20 includes a bottom plate 31, a packaging board 32 arranged on the bottom plate 31, and a plurality of lamp modules 33 arranged on the packaging board 32. The plurality of lamp modules 33 have a plurality of unit lamps 331. The packaging board 32 is provided with a plurality of mounting holes 32a, and each mounting hole 32a is correspondingly connected to each unit lamp 331;

[0037] The wiring layer 40 is embedded in the bottom plate 31, and the wiring layer 40 is connected to the plurality of unit lamps 331.

[0038] Specifically, in the embodiments of the present application, the housing 10 is the housing of an electronic cigarette, and the digital display screen 20 is used to display information such as time, date, temperature, etc. The packaging board 32 is used to carry and fix the lamp modules 33, and is provided with precise mounting holes 32a, so that each unit lamp 331 can be accurately aligned, improving the assembly efficiency, reducing the error rate, and at the same time maintaining high display quality. The wiring layer 40 is embedded in the bottom plate 31 and connects each unit lamp 331 to transmit power and signals, thus reducing the use of additional wires, reducing the failure rate, and at the same time further reducing the occupation of internal space, which helps to reduce the thickness of the product.

[0039] Further, multiple unit lamps 331 form a pattern according to a specific arrangement order, thereby forming multiple lamp modules 33. The information of the digital display screen 20 is transmitted through the lamp modules 33 formed by the multiple unit lamps 331. By arranging the multiple unit lamps 331 in specific mounting holes 32a, power is transmitted to the multiple unit lamps 331 through the wiring layer 40. The encapsulation board 32 can be selected with a thickness of 0.1 mm, and the bottom board 31 can be a thin FR4 or other high-frequency low-thickness substrate materials, such as FR4 with a thickness of 0.3 mm or 0.4 mm, and the thickness of the embedded wiring layer 40 is 0.2 mm to 0.3 mm, thereby reducing the overall thickness. In actual design, adjustments should be made in combination with material, manufacturing process, and electrical performance requirements.

[0040] In a specific embodiment, the encapsulation board 32 further includes an adhesive layer 34, and the adhesive layer 34 is sandwiched between the multiple unit lamps 331 and the multiple mounting holes 32a.

[0041] Specifically, the main function of the adhesive layer 34 is to firmly fix each unit lamp 331 in the mounting hole 32a on the encapsulation board 32, ensuring a stable and reliable connection between the unit lamp 331 and the mounting hole 32a, so as to prevent the unit lamp 331 from falling off or shifting during use, thereby ensuring the display effect and stability of the digital display screen 20.

[0042] In a specific embodiment, the adhesive layer 34 is a conductive adhesive.

[0043] Specifically, as a specific implementation of the adhesive layer 34, the conductive adhesive not only has an adhesive effect but also has electrical conductivity. The conductive adhesive can transmit the current and signals in the circuit while fixing the unit lamp 331.

[0044] Further, during the assembly process, the conductive adhesive is filled in each mounting hole 32a or on each unit lamp 331, and then the unit lamp 331 is placed at the predetermined position of the mounting hole 32a on the encapsulation board 32. After the conductive adhesive is filled, it needs to be cured, and the curing process can be carried out by natural drying, heating, or other appropriate methods. After the conductive adhesive is cured, the unit lamp 33,1 is firmly fixed on the encapsulation board 32 and is electrically connected to other circuit elements on the digital display screen 20. When the electronic cigarette device is powered on, the current and signals are transmitted to the unit lamp 331 through the conductive adhesive, driving the unit lamp 331 to emit light, thereby displaying key information on the digital display screen 20.

[0045] In a specific embodiment, the digital display screen 20 is provided with heat dissipation slits 20c, and the heat dissipation slits 20c are arranged between each lamp module 33.

[0046] Specifically, heat dissipation gaps 20c are provided between each lamp module 33, enabling each lamp module 33 to provide a heat dissipation path and reducing the operating temperature of the lamp module 33. When the unit lamp 331 starts to operate and generates heat, the heat is more effectively conducted out of the lamp module 33 through the heat dissipation gaps 20c, increasing the area of the bottom plate 31, so that the air can carry away the heat and reduce the temperature of the entire digital display screen 20.

[0047] In a specific embodiment, the housing 10 further includes a protective member 11. The housing 10 is provided with a light passing hole 10a, the protective member 11 is disposed on the light passing hole 10a, and the digital display screen 20 is disposed opposite to the light passing hole 10a.

[0048] Specifically, the protective member 11 can be made of a transparent or semi-transparent material, such as glass or plastic, covering the light passing hole 10a of the housing 10 to further protect the digital display screen 20 from direct physical damage, such as scratches or impacts, while allowing the light of the digital display screen 20 to pass through. The light passing hole 10a is an opening on the housing 10, and the position and size of the light passing hole 10a exactly allow the internal digital display screen 20 to display information through the light passing hole 10a, enabling the information on the digital display screen 20 to be clearly seen by the user.

[0049] In a specific embodiment, the housing 10 further includes a support plate 12. The support plate 12 is connected to the light passing hole 10a, and with the extending direction of the protective member 11 as the first direction, the support plate 12 is disposed perpendicular to the first direction.

[0050] Specifically, the support plate 12 can be made of a rigid material for providing additional physical support and protection. The support plate 12 is divided into two parts, respectively disposed at the connection of the housing 10 and the light passing hole 10a on the digital display screen 20, for providing a support and protection function for the multiple lamp modules 33 of the digital display screen 20, ensuring that the housing 10 around the light passing hole 10a will not deform due to external pressure or impact and squeeze the multiple lamp modules 33 on the digital display screen 20.

[0051] In a specific embodiment, a limiting component 13 is provided in the inner cavity of the housing 10. The limiting component 13 includes a first limiting layer 131 and a second limiting layer 132, and the first limiting layer 131 and the second limiting layer 132 are adjacent and disposed on the side wall of the inner cavity.

[0052] In a specific embodiment, the digital display screen 20 has a fixing portion 20a. The fixing portion 20a can extend between the first limiting layer 131 and the second limiting layer 132, and a limiting groove 20b is opened in the fixing portion 20a, so that the limiting groove 20b is disposed on the second limiting layer 132.

[0053] In a specific embodiment, the housing 10 further includes a gold finger 14, and the gold finger 14 is electrically connected to the digital display screen 20.

[0054] Specifically, when the electronic cigarette device or the electronic device using the digital display screen 20 is assembled, the gold finger 14 is precisely placed inside the housing 10 and aligned with the corresponding connection points of the digital display screen 20. By contacting the connection points of the gold finger 14 and the digital display screen 20, a stable electrical connection between the circuit board and the digital display screen 20 is achieved. When the device is powered on, power and signals are transmitted to the digital display screen 20 through the gold finger 14 to drive the lamp module 33 on the digital display screen 20 to display relevant information. Key information such as battery power, voltage, and usage time can be observed through the digital display screen 20, and the gold finger 14 ensures the accurate transmission and display of this information.

[0055] In a specific embodiment, the gold finger 14 is provided with anti-slip grooves 141, and the anti-slip grooves 141 are provided on the outer surface of the gold finger 14.

[0056] Specifically, the anti-slip grooves 141 are a series of small grooves or protrusions for increasing the friction of the gold finger 14.
