[0053] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0054] The terms "first," "second," and "third" used in this application are for descriptive purposes only and should not be construed as indicating or implying the quantity or order of the indicated technical features relative to their importance. All directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship or movement of the components in a specific orientation (as shown in the accompanying drawings). If the specific orientation changes, the directional indication will also change accordingly. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or devices.
[0055] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0056] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be intervening elements. When an element is referred to as being "connected to" another element, it can be directly connected to the other element, or there may be one or more intervening elements. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.
[0057] It should be noted that the embodiments of this application provide a processing method for the housing of an aerosol generating device and an aerosol generating device. The aerosol generating device can be used in conjunction with an aerosol generating product to generate aerosols.
[0058] Aerosol generating articles may include a mouthpiece, a connecting section, and a tobacco segment capable of generating aerosols. The connecting section, located between the mouthpiece and the tobacco segment, guides the aerosol to the mouthpiece. The mouthpiece is for a user to hold in their mouth, allowing the user to inhale the aerosol by sucking on the mouthpiece. The tobacco segment in the aerosol generating article may contain an aerosol generating matrix.
[0059] As used herein, the term "aerosol-generating matrix" refers to a matrix capable of releasing volatile substances to form inhalable aerosols. The aerosol-generating matrix may include tobacco-containing materials containing volatile tobacco flavor compounds that are released from the substrate upon heating. Specifically, the aerosol-generating matrix may be a tobacco-containing aerosol-generating matrix or an aerosol-generating matrix containing solid tobacco. Alternatively, the aerosol-generating matrix may include non-tobacco materials. The aerosol-generating matrix may also include aerosol-forming agents. Examples of suitable aerosol-forming agents are glycerol and propylene glycol.
[0060] If desired, the aerosol generating matrix may contain additional tobacco or non-tobacco volatile flavor compounds released when the aerosol generating matrix is heated. The aerosol generating matrix may also contain microcapsules, such as those containing additional tobacco or non-tobacco volatile flavor compounds, and these microcapsules may melt during heating of the solid aerosol generating matrix.
[0061] The aerosol-generating article can be generally a rod-shaped structure extending longitudinally. The mouthpiece can be positioned adjacent to the proximal end of the aerosol-generating article. The tobacco segment can be positioned adjacent to the distal end of the aerosol-generating article.
[0062] The heating element releases heat to 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 exit from the proximal end of the matrix and be inhaled into the user's mouth.
[0063] This application provides a method for processing a housing for an aerosol generating device, as shown in Figure 1, including:
[0064] A receiving portion is provided on the surface of the housing;
[0065] The curing medium is dripped into the receiving part using an ink-dropping process;
[0066] The curing medium is cured.
[0067] It should be noted that after the curing medium cures, it forms a cured layer embedded within the receiving portion. During the curing process, the curing medium adheres to the inner wall of the receiving portion; after the cured layer is formed, it is tightly embedded within the receiving portion.
[0068] This application uses an ink-dropping process to place a curing medium in the receiving part on the surface of the housing. After the curing medium cures, a curing layer is formed. The curing layer located in the receiving part is not easy to fall off or wear away, and the surface is flat and beautiful. This makes it less likely for abnormal risks such as curing layer falling off or being worn through to expose the substrate when the housing surface of the aerosol generating device is subjected to tests such as paper tape friction test, alcohol friction test, salt spray test, and boiling water test.
[0069] In one embodiment of this application, ink droplet printing is a printing technique that involves dropping ink onto a substrate to form an image or text. It typically involves using an inkjet printhead to precisely eject tiny ink droplets onto paper, plastic, metal, or other materials. This technique can produce high-resolution images and is suitable for a wide variety of substrates.
[0070] In one embodiment of this application, the ink-dropping process can be carried out by inkjet printing, which drops 50μm-60μm of curable medium onto a predetermined position. The position of the ink droplets is achieved by the precise and fine movement of the ink head, which can move up to 1000 dots per inch. By using multiple ink cartridges of different colors, images with full color can be printed.
[0071] In one embodiment of this application, the curing medium includes a thermochromic medium. The housing of the aerosol generating device is provided with a cured thermochromic material. When the heating element transfers heat to the housing during operation, the thermochromic material on the housing changes color, allowing the user to observe that the aerosol generating device is in operation. Furthermore, the ink volume in the ink-dispensing process is larger than that in screen printing and pad printing, resulting in a larger amount of thermochromic material in the containment area, thus leading to a better color response from the thermochromic material.
[0072] In one embodiment of this application, in the step of dripping the curing medium into the receiving portion using a dripping ink process, the temperature of the dripping ink process is 10°C-25°C, and the dripping ink process is generally carried out at room temperature. In another embodiment of this application, the temperature of the dripping ink process is 10°C, 15°C, 18°C, 20°C, 22°C, or 25°C.
[0073] In one embodiment of this application, as shown in FIG2, the receiving portion is a groove. In the step of dripping the curing medium into the receiving portion through the ink-drip process, the curing medium is directly dripped into the groove. In one embodiment of this application, the groove may include a channel with one end open and the other end closed, and the curing medium can be dripped in from the opening of the groove.
[0074] In one embodiment of this application, the bottom wall of the groove is an inclined slope. In the step of dripping the curing medium into the receiving part by the ink dripping process, the nozzle used for dripping ink is opposite to the highest or lowest point of the inclined slope. In the ink dripping process, the solid medium can flow along the bottom of the groove, which makes it easy for the solid medium to fill the groove.
[0075] In one embodiment of this application, the cross-sectional area of the groove parallel to the shell surface gradually changes along the direction from the outer surface of the shell to the inner surface of the shell. In another embodiment, the cross-sectional area of the groove parallel to the shell surface gradually decreases along the direction from the outer surface of the shell to the inner surface of the shell, facilitating the dripping of solid media into the groove during the ink-dispensing process. Furthermore, when the amount of dripped curing media is constant, it has a large surface area on the shell surface, facilitating the curing of the curing media in the groove. In another embodiment, the cross-sectional area of the groove parallel to the shell surface decreases along the direction from the outer surface of the shell to the inner surface of the shell, facilitating the dripping of thermochromic media into the groove during the ink-dispensing process. Furthermore, when the amount of dripped thermochromic media is constant, it has a large surface area on the shell surface, facilitating the curing of the thermochromic media in the groove. This ensures sufficient thermochromic media is displayed on the shell surface, resulting in a good color-changing effect on the shell. In yet another embodiment, the cross-sectional area of the groove parallel to the shell surface gradually increases along the direction from the outer surface of the shell to the inner surface of the shell, making the cured layer located within the groove less prone to being worn away.
[0076] In one embodiment of this application, as shown in FIG3, the receiving part is a through hole. In the step of dripping curing medium into the receiving part by the ink dripping process, the housing is placed on the positioning plane and the positioning plane blocks one side of the through hole. The dripping nozzle for dripping ink drips the curing medium into the through hole from the other side of the through hole.
[0077] In one embodiment of this application, the cross-sectional area of the through-hole parallel to the shell surface gradually changes along the direction from the inner surface of the shell to the outer surface of the shell, facilitating the flow of the curing medium from one side of the inner surface of the shell to the entire through-hole. In one embodiment of this application, the cross-sectional area of the through-hole parallel to the shell surface gradually decreases along the direction from the inner surface of the shell to the outer surface of the shell. In one embodiment of this application, the cross-sectional area of the through-hole parallel to the shell surface gradually increases along the direction from the inner surface of the shell to the outer surface of the shell.
[0078] In one embodiment of this application, the through hole and the groove may include a pattern or icon that presents a certain shape, such as a brand's trademark.
[0079] In one embodiment of this application, when the housing is a metal shell, the step of providing a receiving portion on the surface of the housing specifically includes forming a through hole or groove on the surface of the metal shell through machining. In one embodiment of this application, the machining includes computer-controlled precision machining.
[0080] In one embodiment of this application, when the shell is a plastic shell, the step of setting the receiving part on the surface of the shell specifically includes pre-reserving a countersunk platform on the mold, thereby forming a through hole or groove on the plastic shell.
[0081] In one embodiment of this application, the curing medium contains hard particles, giving the surface of the cured layer a rough texture. In another embodiment of this application, the hard particles include metal particles or plastic particles, giving the surface of the cured layer a frosted metallic or plastic texture.
[0082] In one embodiment of this application, the viscosity of the curing medium is 5000 MPa·s-9000 MPa·s. Curing media with viscosities within this range have suitable surface tension, resulting in a smooth and aesthetically pleasing surface after curing. In one embodiment of this application, the viscosity of the curing medium is 5000 MPa·s, 5500 MPa·s, 6000 MPa·s, 6500 MPa·s, 7000 MPa·s, 75000 MPa·s, 8000 MPa·s, 8500 MPa·s, or 9000 MPa·s.
[0083] In one embodiment of this application, the thermochromic medium includes ink, a curing agent, and a diluent, with a mass ratio of ink, curing agent, and diluent of 10:1:(10-15). In one embodiment of this application, the mass ratio of ink, curing agent, and diluent is 10:1:10. In one embodiment of this application, the mass ratio of ink, curing agent, and diluent is 10:1:12. In one embodiment of this application, the mass ratio of ink, curing agent, and diluent is 10:1:15.
[0084] In one embodiment of this application, curing is high-temperature curing, with a curing time of 15-90 minutes and a curing temperature of 50-90°C. In another embodiment of this application, the curing medium used for high-temperature curing is typically a medium whose molecular structure changes at high temperatures, thereby causing the curing medium to solidify.
[0085] In one embodiment of this application, the step of curing the curing medium specifically includes: high-temperature curing including a first high-temperature curing and a second high-temperature curing, wherein the curing temperature of the first high-temperature curing is 50℃-70℃ and the curing time of the first high-temperature curing is 10min-20min; and the curing temperature of the second high-temperature curing is 70℃-90℃ and the curing time of the second high-temperature curing is 15min-70min.
[0086] In one embodiment of this application, the shell is left to stand for 20-40 minutes before the first high-temperature curing.
[0087] In one embodiment of this application, after the first high-temperature curing, the processing method further includes: observing the surface of the shell, and if there is ink overflow, wiping away the overflow ink.
[0088] In one embodiment of this application, after the curing medium is applied to the receiving portion via the ink-dropping process, the curing medium is first allowed to stand for 30 minutes. Then, it undergoes a first high-temperature curing process at 65°C for 15 minutes. The surface of the casing is then observed, and any ink overflow is wiped away. Finally, a second high-temperature curing process at 80°C for 60 minutes is performed, resulting in a smooth and aesthetically pleasing surface. This curing method, involving standing, a first high-temperature curing, and a second high-temperature curing, allows for the removal of ink overflow during the ink-dropping process after the first high-temperature curing, enabling product rework and significantly improving product yield.
[0089] In one embodiment of this application, after the curing medium is applied to the receiving portion via an ink-dropping process, the cured layer is obtained by directly curing at a temperature of 70°C-90°C for 15-70 minutes. This curing method requires strict control of the amount of ink dropped during the ink-dropping process to avoid ink overflow.
[0090] In one embodiment of this application, curing includes ultraviolet (UV) curing, with a curing time of 1-5 minutes and a curing temperature of 10°C-25°C. In another embodiment, UV curing refers to the process where, under UV radiation (300-800 nm) of medium- or short-wavelength UV light, the photoinitiator in a liquid UV material is stimulated to become free radicals or cations, thereby initiating the polymerization of a polymer (resin) containing active functional groups into an insoluble and infusible solid coating. The time required for UV curing is generally short. In one embodiment of this application, the curing medium is cured for 2 minutes under UV light irradiation to obtain a cured layer.
[0091] In one embodiment of this application, the curing medium is a medium containing fluorescent components. After high-temperature curing or ultraviolet curing, a curing layer with fluorescent effect is obtained. When the external light changes, the curing layer can show different colors.
[0092] This application provides an aerosol generating device 10, as shown in FIG4, including a housing 1 and a curing layer 31. The housing 1 is provided with a receiving portion 11, and the receiving portion 11 is provided with a curing layer 31 formed by an ink-dropping process. The curing layer 31 formed by the ink-dropping process is not easy to fall off or wear away, and has a smooth and beautiful surface. This makes it less likely that abnormal risks such as curing layer falling off or wearing through and exposing the substrate will occur when the surface of the housing of the aerosol generating device is subjected to tests such as paper tape friction test, alcohol friction test, salt spray test, and boiling water test.
[0093] In one embodiment of this application, the cured layer 31 includes a thermochromic material 32. The ink application rate in the ink-dropping process is larger than that in screen printing and pad printing, resulting in a larger amount of thermochromic material in the containment area, thus leading to a better color response of the thermochromic material 32.
[0094] In one embodiment of this application, the thermochromic material 32 includes thermochromic ink, the color of which changes with temperature.
[0095] This application provides an aerosol generating device 10, including a housing 1, a heating element 2, and a thermochromic material 32. The heating element 2 is disposed within the housing 1. The housing 1 has a receiving portion 11, and the receiving portion 11 is provided with the cured thermochromic material 32. The thermochromic material 32 in the housing 10 of the aerosol generating device 10 provided in this application, when the heating element 2 transfers heat to the housing 1 during operation, the thermochromic material 32 on the housing 1 will change color, thus allowing the user to observe that the aerosol generating device 10 is in operation.
[0096] In one embodiment of this application, the thermochromic material 32 refers to a material that displays one color when the temperature is below a preset temperature, and displays another color when the preset temperature is reached or exceeded. This allows users to intuitively determine whether the temperature of the thermochromic material 32 is above the preset temperature by observing the color change. In one embodiment of this application, the colors of the thermochromic material 32 before and after the color change can be achieved by selecting different material formulations. In one embodiment of this application, the thermochromic material 32 is yellow before the color change and red after the color change. In one embodiment of this application, the thermochromic material 32 is green before the color change and yellow after the color change. In one embodiment of this application, the thermochromic material 32 is yellow before the color change and orange after the color change. In one embodiment of this application, the color-changing temperature of the thermochromic material 32 is 25℃-35℃. In one embodiment of this application, the color-changing temperature of the thermochromic material 32 is 25°C, 28°C, 30°C, 32°C or 35°C.
[0097] In one embodiment of this application, the receiving portion 11 is configured in a certain shape, such as a specific pattern or logo.
[0098] In one embodiment of this application, the thermochromic material 32 is formed in the receiving portion 11 of the housing 1 by curing. In one embodiment of this application, curing means that the thermochromic material 32 is in a liquid state before curing and in a solid state after curing. The thermochromic material 32 formed in the receiving portion 11 by curing has a relatively tight bond with the receiving portion of the housing 1, and no adhesive or other fixing methods are required.
[0099] In one embodiment of this application, the layered structure formed by the curing layer 31, that is, the thickness of the curing layer 31 is less than or equal to the thickness of the shell 1, that is, the size of the thermochromic material 32 in the thickness direction of the shell 1 is less than the size of the shell 1, so that the thermochromic material 32 will not extend beyond the inner and outer surfaces of the shell 1 in the thickness direction of the shell 1, thereby the thermochromic material 32 disposed on the shell 1 is not easily scratched and falls off.
[0100] In one embodiment of this application, the receiving portion 11 is disposed at the position corresponding to the heating component 2. In one embodiment of this application, the position on the housing 1 of the aerosol generating device 10 corresponding to the heating component receives the most heat through conduction. The receiving portion 11 is disposed at the position corresponding to the heating component 2, so that the thermochromic material 32 is disposed on the housing 1 at the position corresponding to the heating component 2. Thus, the thermochromic material 32 can detect the area on the housing 1 where the heat is most severe, and the user can more intuitively observe the color change of the thermochromic material 32 and thus perceive the change in the surface temperature of the housing 1.
[0101] In one embodiment of this application, the housing 1 includes a metal housing or a plastic housing. In another embodiment of this application, the housing 1 includes a metal housing, which is a good conductor of heat, facilitating the heat-generating component 2 to conduct heat to the housing 1.
[0102] In one embodiment of this application, the housing 1 includes a stainless steel housing or an aluminum alloy housing, which are good conductors of heat, facilitating the heat-generating component 2 to conduct heat to the housing 1.
[0103] In one embodiment of this application, the receiving portion 11 includes a through hole 111 or a groove 112, and the thermochromic material 32 is disposed within the through hole 111 or the groove 112. In one embodiment of this application, when the housing 1 is a metal housing, the through hole 111 or the groove 112 can be formed by precision machining under computer digital control. In one embodiment of this application, when the housing 1 is a plastic housing, a countersunk platform can be pre-formed on the plastic housing to form the through hole 111 or the groove 112.
[0104] In one embodiment of this application, the groove 112 may include a groove that is open at one end and closed at the other end, and the curing medium can be dripped in from the opening of the groove 112.
[0105] In one embodiment of this application, when the receiving part 11 is a groove 112, the bottom wall of the groove 112 is an inclined surface. In the ink-dropping process, the solid medium can flow along the bottom surface of the groove 112, which makes it easy for the solid medium to fill the groove 112.
[0106] In one embodiment of this application, the cross-sectional area of the groove 112 parallel to the surface of the housing 1 gradually changes along the direction from the outer surface of the housing 1 to the inner surface of the housing 1. In another embodiment, the cross-sectional area of the groove 112 parallel to the surface of the housing 1 gradually decreases along the direction from the outer surface of the housing 1 to the inner surface of the housing 1. This facilitates the dripping of solid media into the groove 112 during the ink-dispensing process. Furthermore, when the amount of dripped curing media is constant, it has a large surface area on the surface of the housing 1, facilitating the curing of the curing media in the groove 112. In yet another embodiment, the cross-sectional area of the groove 112 parallel to the surface of the housing 1 gradually decreases along the direction from the outer surface of the housing 1 to the inner surface of the housing 1. This facilitates the dripping of thermochromic media into the groove 112 during the ink-dispensing process. Furthermore, when the amount of dripped thermochromic media is constant, it has a large surface area on the surface of the housing 1, facilitating the curing of the thermochromic media in the groove 112. This ensures that sufficient thermochromic media is displayed on the surface of the housing 1, resulting in a good color-changing effect on the housing 1. In one embodiment of this application, the cross-sectional area of the groove 112 parallel to the surface of the housing 1 gradually increases along the direction from the outer surface of the housing 1 to the inner surface of the housing 1, making the cured layer 31 located in the groove 112 less likely to be worn away.
[0107] In one embodiment of this application, the through hole 111 may include openings at both ends, allowing the curing medium to be dripped into the through hole 111 during the ink-drip process.
[0108] In one embodiment of this application, when the receiving portion 11 has a through hole 111, the cross-sectional area of the through hole 111 parallel to the surface of the housing 1 decreases along the direction from the inner surface of the housing 1 to the outer surface of the housing 1, facilitating the flow of the curing medium from one side of the inner surface of the housing 1 to the entire through hole 111. In one embodiment of this application, the cross-sectional area of the through hole 11 parallel to the surface of the housing 1 gradually decreases along the direction from the inner surface of the housing 1 to the outer surface of the housing 1. In one embodiment of this application, the cross-sectional area of the through hole 111 parallel to the surface of the housing 1 gradually increases along the direction from the inner surface of the housing 1 to the outer surface of the housing 1.
[0109] In one embodiment of this application, the thermochromic material 32 is recessed inward from the surface of the housing 1, which can reduce the direct contact between the thermochromic material 32 and external hard objects, effectively prevent the housing 1 from being worn or scratched in daily use, and greatly extend the service life of the ink.
[0110] In one embodiment of this application, the thickness of the cured layer 31 is greater than or equal to 0.25 mm. In another embodiment of this application, the thickness of the thermochromic material 32 is greater than or equal to 0.25 mm. When the thickness of the thermochromic material 32 is greater than or equal to 0.25 mm, the receiving portion 11 can accommodate sufficient thermochromic material 32, so that when the temperature of the housing 1 reaches or exceeds a preset temperature, the thermochromic material 32 can change color. In one embodiment of this application, the thickness of the thermochromic material 32 is 0.25 mm, 0.30 mm, 0.35 mm, 0.40 mm, 0.45 mm, 0.50 mm, 0.55 mm, 0.58 mm, 0.60 mm, or 0.65 mm.
[0111] It should be noted that the preferred embodiments of this application are given in the specification and accompanying drawings, but are not limited to the embodiments described in this specification. Furthermore, those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
