[0035] Please refer to Figure 1 , Figure 2 and Figure 3The first embodiment of the present application provides an electronic atomizer 100, comprising: a shell assembly 20, a light-emitting assembly 10, and an oil cup assembly 30; the light-emitting assembly 10 can be electrically connected with an electronic control assembly 40, the brightness and color change of the light-emitting assembly 10 are controlled through the electronic control assembly 40, and the operation can be performed through a button, a touch screen, or a smart phone application. The electronic control assembly 40 can also include accessories such as a battery, and the electronic atomizer 100 also includes accessories such as an atomizing core 50, which will not be described here. The light-emitting assembly 10 emits light after being powered on, realizing the light display effect of the electronic atomizer 100; the oil cup assembly 30 is used to accommodate the liquid aerosol generating substrate; the oil cup assembly 30 can be made of PCTG (transparent plastic) material and formed by mold injection. The shell assembly 20 and the light-emitting assembly 10 jointly form a containing cavity for accommodating the oil cup assembly 30. The shell assembly 20 includes a suction nozzle 21, a sealing silica gel 22, and other components, and the sealing silica gel 22 is used for interference fit with the oil cup assembly 30 to seal the outlet end of the oil cup assembly 30; the sealing silica gel 22 can be made of silica gel material and formed by mold injection.

[0036] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , wherein the light-emitting assembly 10 includes a light-emitting layer 11, a light-guiding layer 12, and a light-uniform layer 13. The light-emitting layer 11, the light-guiding layer 12, and the light-uniform layer 13 are sequentially assembled; the light-emitting layer 11 is used to emit light after being powered on; the light-emitting layer 11 includes a flexible substrate 111 and a light-emitting piece 112 electrically connected to one side surface of the flexible substrate 111; the flexible substrate 111 serves as a connection circuit and a support structure of the light-emitting piece 112, has flexibility, so that the entire light-emitting assembly 10 can be easily attached to surfaces of various shapes, increasing the flexibility of design. The flexible substrate 111 installs the light-emitting piece 112 on one side surface of the flexible substrate 111, and the light-emitting piece 112 emits light after the flexible substrate 111 is powered on. The present application does not limit the number of light-emitting pieces 112. The flexible substrate 111 can be a flexible circuit board, such as being made of a polyimide (PI) film or a polyester (PET) film, having good flexibility and electrical insulation; the flexible substrate 111 can also be a flexible structure composed of a wire and a base material, or other possible flexible conductive structures, facilitating installation and power-on. The flexible substrate 111 surrounds the oil cup assembly 30 and is attached to the oil cup assembly 30, which helps to realize the compact installation of the light-emitting assembly 10 in the electronic atomizer 100 and reduce the space occupation. The terminal of the flexible substrate 111 can be inserted into the electronic control assembly 40. In another embodiment, the light-emitting layer 11 can be divided into several parts and attached around the outer periphery of the oil cup assembly 30, and the light-guiding layer 12 can also be divided into several parts and separately matched with several light-emitting layers 11.

[0037] The light emitting piece 112 can select a high-power and high-brightness light emitting diode. The light emitting diode is mounted on the flexible circuit board by welding or other fixing methods, which is convenient for production. The light emitting piece 112 can select a side light emitting device, that is, the light emitting piece 112 is arranged as a side light emitting device. The side light emitting device is specially designed to make the light uniformly scattered from the side, instead of only emitting light from the top as in traditional light emitting devices. Due to the special design structure of the side light emitting device, uniform light emission can be achieved, reducing the local brightness difference and making the lighting effect more balanced. By using the side light emitting device, the light emitting assembly 10 can achieve more uniform, more efficient and more energy-saving lighting effect, while having better durability and design flexibility. The application of this side light emitting technology provides new possibilities for the design and application of the light emitting assembly 10, especially in space-limited or uniform lighting effect required occasions, such as the electronic atomizer 100.

[0038] The light guide layer 12 has a guiding effect on the light emitted by the light emitting layer 11, and can guide the light emitted by the light emitting piece 112 to the area that needs to be illuminated. Through condensation and scattering, the light is more uniformly irradiated, thereby improving the lighting effect. The light guide layer 12 is arranged in layers with the light emitting layer 11, which improves the guiding effect of the light guide layer 12 on the emitted light of the light emitting layer 11. The light guide layer 12 includes a first surface 121 and a second surface 122 arranged opposite to each other, and the first surface 121 faces the flexible substrate 111. The light guide layer 12 is provided with a receiving groove 123 located on the first surface 121, so that the light emitting piece 112 can be embedded in the receiving groove 123 to achieve the fixing effect of the light emitting piece 112, and ensure the effective transmission of light. The flexible substrate 111 can be fully attached to the first surface 121, so that the overall structure of the light emitting assembly 10 is compact, which helps to reduce the structural space of the light emitting assembly 10. The light guide layer 12 can be made of transparent or translucent plastic materials such as polymethyl methacrylate (PMMA), which cooperates with the oil cup assembly 30 and the gap between the suction nozzle 21.

[0039] The light uniformization layer 13 has a special light scattering texture or structure on the surface, which is used to uniformly scatter the light conducted by the light guide layer 12, thereby achieving a soft and uniform light effect. The light uniformization layer 13 is arranged in layers with the light guide layer 12, and the light uniformization layer 13 is arranged corresponding to the second surface 122, which further reduces the overall space occupation of the light emitting assembly 10. The light uniformization layer 13 and the shell assembly 20 form an accommodating cavity to accommodate the oil cup assembly 30.

[0040] The light-emitting layer 11, the light guide layer 12, and the light uniformization layer 13 are stacked to make the overall structure of the light-emitting assembly 10 occupy a small space after installation, which is beneficial to improve the design flexibility and portability. The light emitted by the light-emitting layer 11 passes through the light scattering of the light guide layer 12 and the light uniformization layer 13 in turn to ensure the uniformity of the light emitted by the light-emitting assembly 10. Through the guiding and uniform dispersion of the light emitted by the light-emitting element 112 by the light guide layer 12 and the light uniformization layer 13, the uniform light-emitting effect is achieved, which effectively avoids the local brightness highlighting of the area where the light-emitting element 112 is located, avoids the phenomenon of exposed lamp beads and uneven brightness, and helps to achieve a large-area display effect, reduces the number of light-emitting elements 112, reduces the cost, and improves the convenience of maintenance and replacement.

[0041] When the electronic atomizer 100 is working, the electric control assembly 40 supplies power to the light-emitting layer 11, and the light-emitting layer 11 emits light. These light rays are first guided by the receiving groove 123 in the light guide layer 12, and then scattered on the first surface 121 of the light guide layer 12. The light rays are further dispersed by the light reflection layer 15 and finally uniformly scattered into the external environment by the light uniformization layer 13. This design not only ensures the uniform distribution of light, but also avoids the direct exposure of the lamp beads, improving the aesthetics and safety of the product. Through this design, the light-emitting assembly 10 and the electronic atomizer 100 provided by the present application solve the problems of the light-emitting display structure in the prior art, such as exposed lamp beads, uneven brightness, large space occupation, and high cost. The double-layer light scattering design ensures the uniformity of the light, while the lamp beads are not exposed, the structure is compact, the assembly is convenient, the cost is effectively reduced, and the defects of the light-emitting display structure in the prior art, such as exposed lamp beads, uneven brightness, space occupation, and high cost, are solved.

[0042] During the installation process of the electronic atomizer 100, the flexible substrate 111 can be attached to the oil cup assembly 30 by using an integrally injection-molded oil cup assembly 30. Then, the power connection terminals of the flexible substrate 111 are inserted into the corresponding terminal seats of the electric control assembly 40. Next, the light guide layer 12 and the light uniformization layer 13 are put on. Then, the shell is nested on the oil cup assembly 30. Finally, the mouthpiece is assembled together.

[0043] Further, the side of the light uniformization layer 13 facing the light guide layer 12 is provided with light scattering textures, which can be micro-structured textures or patterns, for further dispersing and uniformizing the light emitted by the light-emitting element 112. Through the diffusion of the light emitted by the light guide layer 12 by the light scattering textures, the uniform diffusion effect of the light uniformization layer 13 on the light can be further improved, and the uniformity of the light emitted by the light-emitting assembly 10 can be improved.

[0044] Please continue to refer to Figure 3 and Figure 4Further, the uniform light layer 13 and the light guide layer 12 are provided with a gap 14, air is filled in the gap 14, so that the light emitted through the light guide layer 12 enters the uniform light layer 13 through the air gap 14, which helps to reduce the direct reflection of light and increase the scattering effect, further improving the uniformity and softness of the emitted light.

[0045] Please refer to Figure 2 , Figure 5 and Figure 6 Further, the light emitting layer 11 includes a plurality of light emitting pieces 112, and the plurality of light emitting pieces 112 form at least one light emitting strip 113 along a preset direction, which ensures uniform output of light and can independently control the plurality of light emitting pieces 112 as needed to achieve different display effects. The preset direction includes at least one of the length direction of the electronic atomizer 100, perpendicular to the length direction of the electronic atomizer 100, and an angle with the length direction of the electronic atomizer 100, or other directions, which can be adjusted as needed; The first surface 121 of the light guide layer 12 is provided with at least one receiving groove 123 along the preset direction, and the receiving groove 123 is arranged corresponding to the light emitting strip 113, used for receiving the light emitting strip 113, and improving the compactness of the overall structure and reducing the space occupation.

[0046] Further, the light emitting layer 11 includes a plurality of light emitting pieces 112, and the plurality of light emitting pieces 112 are distributed in a mesh shape, which helps to achieve uniform light emission, improve display effect, and reduce the number of light emitting pieces 112, reduce cost, and improve the convenience of maintenance and replacement. The first surface 121 is provided with a receiving groove 123 corresponding to each of the plurality of light emitting pieces 112, and each light emitting piece 112 is embedded in the corresponding receiving groove 123, which improves the compactness of the overall structure and reduces the space occupation.

[0047] Please refer to Figure 3 , Figure 4 and Figure 6 In another embodiment, the light emitting assembly 10 further includes a light reflecting layer 15 attached to the first surface 121, which has a light reflecting effect on the light emitted by the light emitting piece 112, promotes light diffusion, further improves the diffusion effect of the light emitted by the light emitting piece 112 on the light guide layer 12, and further improves the display uniformity of the light emitting assembly 10.

[0048] The application provides a light emitting assembly and an electronic atomizer thereof. The light emitting layer, the light guide layer, and the uniform light layer are stacked, and the light emitted by the light emitting layer passes through the light guide layer and the uniform light layer in sequence, which ensures the uniformity of the light emitted by the light emitting assembly. Through the guidance and uniform dispersion of the light emitted by the light emitting piece by the light guide layer and the uniform light layer, the uniform light emission effect is achieved, which effectively avoids the local brightness highlighting of the area where the light emitting piece is located and avoids the phenomenon of the light bead being exposed.
