[0002] With the rapid development of electronic cigarettes, in order to satisfy consumers' needs for a more intuitive understanding of electronic cigarette related information and status during the use of electronic cigarettes, an integrated display screen is used to display the electronic cigarette's working power output, remaining power, working mode, number of puffs and other information. The existing electronic cigarette display screen assembly structure is supported by a plastic bracket and then installed on the PCB board, and the PCB board is then locked on the outer shell to fix it, and finally the protective lens of the display screen is pasted on the outer shell. The assembly of multiple structural parts in this solution is more troublesome, and the linkage fluctuation of the multiple assembly tolerances is large, resulting in many cases of loose shaking or too tight and difficult to assemble, or for circular display screens, it is easy to assemble the display area of ​​the display screen crooked. For this reason, it is necessary to optimize and improve the existing assembly structure of the electronic cigarette assembly display screen, especially the assembly structure for the circular display screen, to solve the defects of the existing technology. Utility Model Content

[0003] In view of this, the present invention proposes an assembly structure of a display screen of an electronic cigarette to solve the problems of complicated assembly of the existing display screen and easy assembly crookedness of the display area of ​​the display screen.

[0004] The technical solution disclosed in the present utility model is a display screen assembly structure for an electronic cigarette, comprising an electronic cigarette shell, a display screen, a lens and a fixed pressing piece. A through hole for mounting the display screen is provided on the electronic cigarette shell, and an installation groove for mounting the lens and the display screen is provided on the inner side of the through hole along the periphery of the through hole. The lens is embedded in the installation groove, and the display screen is stacked on the back of the lens. The fixed pressing piece is an annular pressing piece with a notch, and the fixed pressing piece is clamped on the outer edge of the display screen. The fixed pressing piece is fixedly connected to the installation groove of the electronic cigarette shell; the installation groove, lens and fixed pressing piece are provided with a positioning structure.

[0005] Furthermore, the through hole, lens, and display area of ​​the display screen are all circular, and the positioning structure is provided with a first straight edge and a second straight edge on the opposite left and right side walls of the mounting slot, and a third straight edge on the upper side wall of the mounting slot; a first straight cut edge A, a second straight cut edge B, and a third straight cut edge C are respectively provided on the left and right side edges and the upper side edge of the lens edge; a first straight cut edge A', a second straight cut edge B', and a third straight cut edge C' are respectively provided on the left and right side edges and the upper side edge of the fixed pressing plate, the first straight cut edge A and the first straight cut edge A' abut against the first straight edge, the second straight cut edge B and the second straight cut edge B' abut against the second straight edge, and the third straight cut edge C and the third straight cut edge C' abut against the third straight edge, forming a circumferential angle positioning for assembling the lens and the fixed pressing plate.

[0006] As one of the solutions, after the display screen and the lens are aligned, they are bonded and fixed with slow-drying semi-solidified resin glue. When the display screen and the lens are correctly aligned, the lens and the positioning structure of the mounting slot are assembled to ensure that the assembled display screen does not display skewed.

[0007] As another solution, after the display screen and the fixed pressure plate are aligned, they are then integrally laminated onto the back of the lens. The outer diameter of the back edge of the lens is larger than the outer edge of the display screen. The fixed pressure plate is pressed against the edge of the back of the lens, and the fixed pressure plate and the back of the lens are bonded together using a slow-drying, semi-curing resin adhesive. When the display screen and the fixed pressure plate are correctly aligned, the positioning structure of the fixed pressure plate and the mounting slot ensures that the assembled display screen does not display skew.

[0008] Furthermore, the display screen adopts a liquid crystal display screen, the display area of ​​the display screen is circular, the lower end of the display screen is a circuit board access end extending obliquely downward, and a first positioning boss and a second positioning boss are respectively provided on both sides of the lower side wall of the installation slot, and the inner sides of the first positioning boss and the second positioning boss are respectively in contact with the two sides of the circuit board access end.

[0009] Furthermore, a connecting ear is provided on the left and right sides of the fixed pressing plate respectively, and a screw connecting column is provided on the left and right sides of the installation slot respectively, and the connecting ear is connected to the screw connecting column by screws.

[0010] The beneficial effects of the present invention are as follows: the assembly structure of the electronic cigarette display screen designed by this technical solution is mainly aimed at the assembly of circular display windows and circular display screens. Due to the assembly of circular components, the circumferential rotation angle of the circular components will cause the assembled display screen to be skewed relative to the display window of the electronic cigarette shell. Therefore, this solution designs the installation grooves for the lens and the fixed pressing plate for installing the display screen, and designs a positioning structure that matches the lens and the fixed pressing plate. In this way, without making special designs for the display screen, the display screen can be positioned and assembled without being skewed by connecting the display screen to the lens, or connecting the display screen to the fixed pressing plate, and then by matching the lens or the fixed pressing plate with the installation groove. The assembly structure of this solution has few components, is simple to assemble, and is conducive to overcoming the assembly problem of the skewed display area presented by the through-hole position of the display screen and the electronic cigarette shell.
