Description

Technical Field

[0001] This utility model relates to the field of aerosol generation technology, and in particular to an aerosol generation device. Background Technology

[0002] With the rapid development of aerosol generation devices in terms of functional diversification and user experience optimization, their structural design is gradually becoming more integrated and personalized.

[0003] Among them, buttons, as the core component of user interaction, not only need to meet the requirements of ease of operation, but also need to take into account the function of status indication. In order to achieve the light indication effect of the button area, a light guide structure is usually embedded inside the button, and then the light emitted by the internal light-emitting element is conducted to the button surface to intuitively reflect the working status of the device.

[0004] However, the relative position between the light guide structure and the light-emitting element can easily cause significant uniformity problems in the light emission effect. Utility Model Content

[0005] The purpose of this invention is to provide an aerosol generating device to ensure the uniformity of the luminescence effect and improve the user's visual experience.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] Aerosol generating apparatus, comprising:

[0008] case;

[0009] The light source is located inside the housing;

[0010] A light guide, at least partially disposed within the housing, facing the light source to receive light, wherein the wall thickness of the light guide near the light source is greater than the wall thickness away from the light source.

[0011] As an alternative to the aerosol generating device, the light guide has an outer surface facing outward from the housing, the outer surface being inclined relative to the light-emitting surface of the light source.

[0012] As an alternative to the aerosol generating device, the light guide has an inner surface that receives light generated by the light source, the inner surface and the outer surface forming a first angle, and the outer surface and the light-emitting surface of the light source forming a second angle, wherein the first angle is equal to the second angle.

[0013] As an alternative to an aerosol generating device, both the outer surface and the inner surface are planar.

[0014] As an alternative solution for an aerosol generating device, the aerosol generating device further includes a button, and the light guide is disposed on the button and moves synchronously with the button.

[0015] As an alternative to the aerosol generating device, the button is provided with a mounting hole, and the light guide is at least partially interference-fitted or snapped into the inner wall of the mounting hole.

[0016] As an alternative to the aerosol generating device, one of the inner wall of the mounting hole and the light guide is provided with a guide post extending along the wall thickness direction of the light guide, and the other is provided with a guide groove, with the guide post placed in the guide groove.

[0017] As an alternative to the aerosol generation device, the light guide is provided with a limiting groove, and a light-shielding element is provided in the limiting groove.

[0018] As an alternative to the aerosol generating device, the aerosol generating device further includes a control board disposed within the housing, and the control board is provided with the light source.

[0019] As an alternative to the aerosol generation device, the light guide has a protrusion on the surface facing the control board, and the control board has a switching element, the protrusion being used to trigger the switching element.

[0020] As an alternative to an aerosol generating device, the outer surface is annular, and multiple light sources are uniformly arranged in the circumferential direction of the outer surface.

[0021] Beneficial effects:

[0022] In this invention, in areas with a larger wall thickness of the light guide, the light from the light source travels a longer path before being emitted, resulting in greater light loss. Conversely, in areas with a smaller wall thickness, the light travels a shorter path before being emitted, resulting in less light loss. By optimizing the wall thickness characteristics of the light guide to mitigate light loss, the light emitted from all positions on the outer surface of the light guide is ensured to be uniform or nearly uniform, allowing the user to observe uniform light. This application adjusts the light-emitting performance of the light guide by varying its wall thickness relative to the light source at different positions, thereby making the emitted light more consistent and ensuring uniform light observed by the user to meet their actual usage needs.

[0038] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0040] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0042] This embodiment relates to an aerosol generating device.

[0043] It should be noted that this aerosol generating apparatus can be used in conjunction with an aerosol generating article, enabling the aerosol generating article to produce aerosols. The aerosol generating article contains an aerosol generating matrix, which may include tobacco-containing materials containing volatile tobacco flavor compounds released from the substrate upon heating. Specifically, the aerosol generating matrix may be an aerosol generating matrix containing liquid tobacco or solid tobacco. Alternatively, the aerosol generating matrix may include non-tobacco materials. The aerosol generating matrix may also include an aerosol forming agent. Suitable examples of aerosol forming agents are glycerol and propylene glycol.

[0044] This aerosol generating device heats the aerosol-generating product, causing the aerosol-generating matrix to produce volatile substances. These volatile substances combine with air flowing into the aerosol-generating matrix to form an aerosol. The air flowing into the aerosol-generating matrix and the aerosol generated by the matrix can then be inhaled into the user's mouth.

[0045] Please refer to the appendix for details. Figure 1 and attached Figure 2 The aerosol generating device 10 includes a housing 1, a light source 2, and a light guide 3. The light source 2 is located inside the housing 1; the light guide 3 is at least partially located inside the housing 1, and the light guide 3 faces the light source 2 to receive light. The wall thickness of the light guide 3 near the light source 2 is greater than the wall thickness away from the light source 2.

[0046] Specifically, the housing 1 is an outer shell used to support and install the internal components of the aerosol generating device 10. The housing 1 can be metal or non-metal. When the housing 1 is non-metallic, it can be manufactured using injection molding; when the housing 1 is metal, it can be manufactured using processes such as calendering and punching. The interior of the housing 1 can be equipped with various positioning structures, mounting structures, and support structures. The shape of the housing 1 can be designed according to the user's grip comfort during use. This housing 1 adopts a cylindrical structure with rounded transitions on the side walls to make it more comfortable for the user to grip the outer wall of the housing 1. The outer wall of the housing 1 can also be further processed with friction textures to help avoid the risk of slippage when the user performs operations such as pressing.

[0047] The light source 2 can be an LED light source, thereby reducing the space occupied inside the housing 1. The LED light source can change color by controlling the mixing of RGB three primary colors, and can also control the conduction time of the LED light source through high-frequency switching signals to adjust the effective brightness, thereby realizing the changing characteristics of various light signals. The status information corresponding to the aerosol generating device 10 helps the user identify the working status. The light emitted from the light-emitting surface of the light source 2 is received by the light guide 3 and led out through the internal light guide path of the light guide 3 to the outer surface 31 of the light guide 3. The outer surface 31 can be set on the top wall of the housing 1 to avoid the user blocking the light led out by the light guide 3 when holding the aerosol generating device 10.

[0048] Based on the user's asymmetry and personalized design requirements for housing 1, the top wall of housing 1 is inclined relative to the light-emitting surface of light source 2. Accordingly, the outer surface 31 of the light guide 3 located on the top wall of housing 1 is naturally inclined relative to the light-emitting surface of light source 2. Due to the inclined setting, the actual light intensity of the emitted light is not consistent at different positions on the outer surface 31, resulting in uneven light on the entire outer surface 31 as observed by the user. This can easily lead to misjudgment by the user and does not meet the user's actual usage needs.

[0049] In this embodiment, in areas of the light guide 3 with a larger wall thickness, the light from the light source 2 travels a longer path before being emitted, resulting in greater light loss. Conversely, in areas of the light guide 3 with a smaller wall thickness, the light from the light source 2 travels a shorter path before being emitted, resulting in less light loss. Since the distance between the outer surface 31 of the light guide 3 and the light-emitting surface of the light source 2 varies at different locations, optimizing the wall thickness of the light guide 3 helps to mitigate light loss, ensuring that all positions on the outer surface 31 of the light guide 3 emit light at the same or nearly uniform rate, thus allowing the user to observe uniform light.

[0050] In this embodiment, by adjusting the wall thickness of the light guide 3 at different positions relative to the light source 2, the light emission performance of the outer surface 31 of the light guide 3 can be adjusted, thereby making the light output of the outer surface 31 of the light guide 3 more uniform, so that the light observed by the user remains uniform, thus meeting the user's actual usage needs.

[0051] Please further refer to the appendix. Figure 3 Optionally, the light guide 3 has an inner surface 32 for receiving light generated by the light source 2. A first angle β is formed between the inner surface 32 and the outer surface 31, and a second angle α is formed between the outer surface 31 and the light-emitting surface of the light source 2. The first angle β is equal to the second angle α. (The α and β in the figure are drawn by parallel auxiliary lines and are therefore only used to illustrate the size of the angles. The specific position of the angles should be determined by referring to the actual inner surface 32, outer surface 31, and light-emitting surface of the light source 2 in this embodiment.)

[0052] Specifically, the inner surface 32 of the light guide 3 facing the light source 2, which is used to directly receive light, is a plane, thus ensuring the continuous and gradual change in the intensity of the received light. The outer surface 31 is also a plane to adapt to the plane state of the inner surface 32, thereby ensuring that the intensity of the emitted light tends to be consistent. When the first included angle β and the second included angle α are equal, the corresponding light loss accumulation at each position of the outer surface 31 can maintain the optimal uniformity of the emitted light. Of course, those skilled in the art will understand that by making the first included angle β and the second included angle α close, the approximate uniformity of the emitted light can also be ensured. This setting is mostly used to adapt to the limitations of the overall structure or size.

[0053] Optionally, the aerosol generating device 10 also includes a button 4, with the light guide 3 disposed on the button 4.

[0054] Specifically, button 4 is mainly used to control different operating states of the aerosol generating device 10. For example, pressing button 4 triggers the start or stop function, and pressing button 4 several times in succession triggers multiple heating modes. Correspondingly, for different operating states, the light source 2 can change its color, change the time interval of light flashing, and use light information characteristics such as constantly on, constantly off, or constantly dim to assist the user in determining the operating state of the aerosol generating device 10.

[0055] In this embodiment, by directly integrating the light guide 3 onto the button 4, the structure can be simplified, avoiding the need for additional limiting holes on the housing 1, which would affect the continuity of the external structure of the housing 1 and ensure the strength of the housing 1.

[0056] Please see the appendix Figure 4 and attached Figure 5Optionally, the button 4 is provided with a mounting hole 41, and the light guide 3 is at least partially interference-fitted or snapped into the inner wall of the mounting hole 41.

[0057] In this embodiment, the mounting hole 41 is a circular hole adapted to the outer contour of the light guide 3. A portion of the light guide 3 is snapped or interference-fitted into the mounting hole 41 to avoid introducing unnecessary connectors. The other portion of the light guide 3 can extend into the internal space of the housing 1 to accommodate different wall thicknesses. Of course, the light guide 3 can also be fixed to the button 4 by adhesive bonding.

[0058] Optionally, one of the inner wall of the mounting hole 41 and the light guide 3 is provided with a guide post 411 extending along the wall thickness direction of the light guide 3, and the other is provided with a guide groove 33, with the guide post 411 placed in the guide groove 33.

[0059] Specifically, the inner wall of the mounting hole 41 is provided with a plurality of guide posts 411, and the outer wall of the light guide 3 is provided with a plurality of guide grooves 33. When the light guide 3 is inserted into the mounting hole 41, the guide posts 411 are placed in the guide grooves 33.

[0060] In this embodiment, the cooperation between the guide post 411 and the guide groove 33 ensures that the light guide 3 has an accurate position on the circumference, and prevents the light guide 3 from rotating due to factors such as vibration, which would damage the original wall thickness and the matching relationship with the light source 2, thereby affecting the uniformity of the emitted light.

[0061] Optionally, the light guide 3 is provided with a limiting groove 35, and a light shield 7 is provided in the limiting groove 35. The surface of the light shield 7 facing the outside of the housing 1 is coplanar with the surface of the button 4.

[0062] Specifically, the outer surface 31 of the light guide 3 is circular, and the light shield 7 makes the light-emitting area ring-shaped, forming a ring-shaped light strip with high visibility. The limiting groove 35 is stepped, and the light shield 7 can be adhered to the limiting groove 35. By ensuring that the surface of the light shield 7 facing outward from the housing 1 is coplanar or parallel to the surface of the button 4 and is very close, it can be ensured that the user's finger will not have obvious pressure when pressing the button 4, thus ensuring the user's experience.

[0063] Optionally, the aerosol generating device 10 also includes a control board 5 disposed inside the housing 1, and the control board 5 is provided with a light source 2.

[0064] In this embodiment, the housing 1 has a receiving groove for positioning the control board 5. The control board 5 is directly embedded in the receiving groove or fixed in the fixing groove using threaded fasteners. The control board 5 is used to control the output current of the light source 2 so that the light source 2 can produce various light emission states.

[0065] Optionally, the light guide 3 has a protrusion 34 on the surface facing the control board 5, and the control board 5 has a switching element 6. The protrusion 34 is used to trigger the switching element 6.

[0066] Specifically, the protrusion 34 is integrally formed on the light guide 3, and the radial dimension of the protrusion 34 is adapted to the trigger end of the switching element 6 to ensure that the trigger end does not deviate when pressed. By pressing the button 4, the entire light guide 3 is moved, and the protrusion 34 triggers the switching element 6 to achieve control over various light emission states of the light source 2.

[0067] Optionally, the outer surface 31 is annular, and multiple light sources 2 are uniformly arranged in the circumferential direction of the outer surface 31.

[0068] In this embodiment, the outer surface 31 of the light guide 3 is formed into a ring, and four light sources 2 are uniformly arranged in the circumferential direction of the outer surface 31, which can be approximately parallel light incident into the light guide 3, thereby improving the uniformity of the emitted light.

[0069] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
