Abstract
Description
Technical Field
[0001] This utility model relates to the field of indicator light guide technology, and in particular to an LED indicator light and light guide structure for electronic cigarettes. Background Technology
[0002] Electronic cigarettes are electronic products that atomize e-liquid into aerosol vapor particles through an electrically heated heating element. With the increasing sophistication of electronic cigarette technology, some existing products include LED indicator lights to display the cigarette's operating status, battery level, and charging status. However, in current products, the LED indicator light is achieved through a separate LED board or by integrating the LEDs into the main board. A light-transmitting hole is located on the corresponding part of the cigarette casing, or a light guide is placed directly in front of the LED indicator light, with a window on the casing exposing the light guide. In this approach, if the cigarette casing is made of translucent plastic or has a translucent plastic lens embedded in it, the direct light from the LED indicator light will scatter around the light guide, causing light leakage around the light guide and affecting the user experience. Therefore, the LED indicator light and light guide structure of electronic cigarettes need to be optimized and improved to solve these problems. Utility Model Content
[0003] To overcome the aforementioned problems in the existing technology, this solution proposes an LED indicator light and light guide structure for electronic cigarettes, which effectively improves the existing solutions for installing LED indicator lights in electronic cigarettes, addressing issues such as uneven light efficiency and light leakage.
[0004] According to one aspect of this solution, an LED indicator light and light guide structure for an electronic cigarette are provided, including:
[0005] One or more LED lights, wherein the one or more LED lights are integrated into an LED light board or integrated into the main control board of an electronic cigarette, and the multiple LED lights are arranged in a row with the same interval;
[0006] A light-shielding component, comprising an upper light-shielding strip and a lower light-shielding strip, the upper light-shielding strip and the lower light-shielding strip are parallel, the lower light-shielding strip abuts against the lower side of one or more LED lights, and the upper light-shielding strip has a gap area between it and the upper side of one or more LED lights.
[0007] A light guide cover, made of a light-transmitting material, is embedded between the upper and lower light-shielding strips. The light guide cover has a corresponding cavity for covering one or more LED lights. The front end of the light guide cover corresponding to the cavity is a light guide entity embedded in the interval area. The top surface of the light guide cover corresponding to the cavity has a first refractive structure, and the bottom of the light guide entity has a second refractive structure. Light from one or more LED lights enters the cavity, is refracted through the first refractive structure to the bottom of the light guide entity, and is refracted through the second refractive structure to exit from the top surface of the light guide entity. The top surface of the light guide entity corresponds to a light-transmitting window of the electronic cigarette casing.
[0008] Furthermore, the light-shielding component includes an upper frame as the upper light-shielding strip, a lower frame as the lower light-shielding strip, a left frame connecting the left sides of the upper and lower light-shielding strips, and a right frame connecting the right sides of the upper and lower light-shielding strips. The upper frame, lower frame, left frame, and right frame are integrally formed from an opaque material. The inner sides of the upper frame, lower frame, left frame, and right frame form a frame for embedding the light guide cover. The inner wall of the frame has a protrusion for securing the light guide cover when it is embedded in the frame.
[0009] Furthermore, the bottom of both the left and right side frames are provided with barbed hook fasteners, and the LED light board or main control board is provided with a snap-fit part that engages with the barbed hook fastener.
[0010] Furthermore, the light guide cover is made of acrylic or glass.
[0011] Furthermore, the first refractive structure is a first refractive pattern on the top surface of the light guide cover corresponding to the concave cavity, or a first optical film with a refractive pattern is attached thereon; the second refractive structure is a second refractive pattern on the bottom of the light guide entity, or a second optical film with a refractive pattern is attached thereon.
[0012] The beneficial effects of this invention are as follows: By designing a light guide structure for LED indicator lights in electronic cigarettes, the LED is changed from facing the light area to being installed to the side, reducing direct light scattering. A first refractive structure is provided on the top surface of the light guide cover corresponding to the concave cavity inside the light guide cover, and a second refractive structure is provided on the bottom of the light guide entity, converting the side light into uniform forward light output, thus solving the problem of uneven light efficiency of LED indicator lights. The addition of a light-shielding component effectively solves the problem of light leakage around the LED light, thereby improving the lighting effect of the electronic cigarette LED indicator light.

[0023] Please refer to Figures 1 to 7 This is a specific embodiment of an LED indicator light and light guide structure for an electronic cigarette disclosed in this technical solution. The electronic cigarette selected is a cartridge-type electronic cigarette structure. It is for illustration purposes only and does not mean that this solution is set on the electronic cigarette host of a cartridge-type electronic cigarette. It can also be set on an integrated electronic cigarette, which will not be listed here.
[0024] In this embodiment, the LED indicator light and light guide structure of the electronic cigarette include:
[0025] One or more LED lights 1, wherein the one or more LED lights 1 are integrated into an LED light 1 board or integrated into the main control board 2 of an electronic cigarette, and the multiple LED lights 1 are arranged in a row with the same interval;
[0026] The light-shielding component 3 includes an upper light-shielding strip and a lower light-shielding strip. The upper light-shielding strip and the lower light-shielding strip are parallel to each other. The lower light-shielding strip abuts against the lower side of one or more LED lights 1. The upper light-shielding strip and the upper side of one or more LED lights 1 are separated by a gap area 201.
[0027] A light guide cover 4 is made of a light-transmitting material and is embedded between the upper light-shielding strip and the lower light-shielding strip. The light guide cover 4 is provided with a cavity 401 for covering one or more LED lights 1. The front end of the light guide cover 4 corresponding to the cavity 401 is a light guide entity 402 embedded in the interval area 201. The top surface of the light guide cover 4 corresponding to the cavity 401 is provided with a first refractive structure 4011, and the bottom of the light guide entity 402 is provided with a second refractive structure 4021. The light from one or more LED lights 1 shines into the cavity 401, is refracted to the bottom of the light guide entity 402 by the first refractive structure 4011, and is refracted out from the top surface of the light guide entity 402 by the second refractive structure 4021. The top surface of the light guide entity 402 corresponds to the light-transmitting window 501 of the electronic cigarette shell 5.
[0028] Please refer to Figures 1 to 3 Furthermore, the light-shielding component 3 includes an upper frame as the upper light-shielding strip, a lower frame as the lower light-shielding strip, a left frame connecting the left sides of the upper and lower light-shielding strips, and a right frame connecting the right sides of the upper and lower light-shielding strips. The upper frame, lower frame, left frame, and right frame are integrally formed using an opaque material. The inner sides of the upper frame, lower frame, left frame, and right frame form a frame for embedding the light guide cover 4. The inner wall of the frame is provided with a protrusion 301, which serves to secure the light guide cover 4 when it is embedded in the frame.
[0029] In addition, the bottom of the left and right side frames are provided with barbed hook buckles 302, and the LED light board 1 or the main control board 2 is provided with a buckle 202 that engages with the barbed hook buckles 302.
[0030] Preferably, the light guide cover 4 is made of acrylic or glass.
[0031] Please refer to Figure 7Furthermore, the first refractive structure 4011 is a first refractive pattern disposed on the top surface of the light guide cover 4 corresponding to the concave cavity 401, or a first optical film with a refractive pattern is attached thereon; the second refractive structure 4021 is a second refractive pattern disposed on the bottom of the light guide entity 402, or a second optical film with a refractive pattern is attached thereon. The process of converting lateral light into uniform forward light is as follows: the light from the LED lamp 1 shines from the concave cavity 401 onto the position of the first refractive structure 4011 corresponding to the light guide cover 4. The light is refracted by the first refractive structure 4011 to the bottom of the light guide entity 402 of the light guide cover 4, and then refracted by the second refractive structure 4021 to the front end of the light guide entity 402, i.e., out through the light-transmitting window 501. Figure 7 The arrows in the diagram illustrate the refraction of light from the LED light. Through refraction, the light from the LED light 1 is refracted into uniform light and emitted, reducing the scattering of direct light.
