Description

Technical Field

[0001] This application relates to the field of aerosol generation, and more particularly to a single-use filter and an aerosol generation device. Background Technology

[0002] Aerosol generating devices heat an aerosol generating matrix, causing it to produce aerosols for users to inhale. These devices typically include a filter through which users can inhale the generated aerosols.

[0003] However, existing filters are reusable and exposed to the air during use, which can lead to the accumulation of dust, bacteria, and viruses, making them unhygienic and resulting in a poor suction experience for users. Utility Model Content

[0004] The purpose of this application is to provide a single-use filter and an aerosol generating device, which aims to solve the technical problem of unhygienic use of existing filters.

[0005] To achieve the above objectives, this application provides a secondary-displacement filter tip, applied in an aerosol generating device, the secondary-displacement filter tip comprising:

[0006] A suction tube, wherein the suction tube has a suction channel inside, the top of the suction tube is used for suction, and the bottom of the suction tube is used for detachable connection to the aerosol generating device.

[0007] A top filter section is located at the top of the suction channel;

[0008] Bottom filter section, wherein the bottom filter section is located at the bottom of the suction channel;

[0009] The aroma-enhancing section is located within the suction channel and between the top filter section and the bottom filter section.

[0010] In the single-use filter of this application, the side wall of the suction tube is provided with a through hole, and the through hole is connected to the suction channel.

[0011] In the secondary filter of this application, the suction channel further includes at least one hollow section.

[0012] In the secondary filter of this application, the bottom filter section includes high-temperature silicone, and the bottom filter section is provided with an air inlet hole extending from the top to the bottom of the bottom filter section.

[0013] In the secondary filter of this application, the top filter section includes filter cotton.

[0014] The single-use filter of this application further includes a first support filter section, and the flavor-enhancing section is disposed between the top filter section and the first support filter section.

[0015] The single-use filter of this application further includes a second support filter section, wherein the aroma-enhancing section is disposed between the bottom filter section and the second support filter section.

[0016] The secondary filter of this application also includes a mist-enhancing section, which is located in the suction channel and is used to increase mist.

[0017] The single-use filter of this application further includes a first filter section, which is disposed within the suction channel and located between the top filter section and the bottom filter section.

[0018] This application also provides an aerosol generating apparatus, including a main unit and a secondary filter as described in any of the above;

[0019] The secondary filter is detachably connected to the main unit, which is equipped with a heating component that can heat the aerosol generating matrix to generate aerosol. The bottom end of the secondary filter is connected to the heating component, and the aerosol can enter the suction channel from the bottom end of the secondary filter.

[0020] The single-use filter and aerosol generating device provided in this application are detachably connected to the aerosol generating device via the bottom of the suction tube. This allows the single-use filter to be used immediately, without being exposed to air when not in use, and ensuring cleanliness and hygiene during use, thus improving the user's inhalation experience. When the user inhales aerosol through the single-use filter, the aerosol enters the suction tube from the bottom filtration section, where it undergoes preliminary filtration. The aerosol is then flavored by the aroma-enhancing section and further filtered by the top filtration section before being inhaled. During this process, condensate generated during the cooling process remains within the suction tube, and the aroma-enhancing section adjusts the aerosol's flavor, further enhancing the user's inhalation experience. Furthermore, the single-use filter ensures that the aerosol is fully filtered and flavored each time the user inhales, further improving the user's inhalation experience. Furthermore, when the disposable filter is discarded, it can remove the carbon deposits generated during the heating process of the aerosol generating matrix, thereby reducing carbon deposits and other sediments in the aerosol generating device, making it easier to keep the aerosol generating device clean, reducing the frequency of cleaning, and making it hygienic and environmentally friendly.

[0038] In related technologies, aerosol generating devices typically include a filter, through which users can inhale the generated aerosol. To maximize filter utilization and reduce costs, the filter is generally reused multiple times. During use, the filter is exposed to the air; even some unprotected filters are exposed to the air when the aerosol generating device is not in use, making them prone to accumulating dust, bacteria, and viruses. Therefore, using the filter is unhygienic, leading to a poor inhalation experience for the user. Furthermore, the flavoring and filtration structures within the filter are consumed during repeated use, further diminishing the user's inhalation experience after multiple uses.

[0039] Therefore, this application provides a single-use filter and an aerosol generating device, which can ensure the cleanliness and hygiene of the single-use filter when the user uses the aerosol generating device, thereby improving the user's suction experience.

[0040] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0041] like Figure 1 As shown in the embodiment of this application, the secondary filter tip is applied to an aerosol generating device. The secondary filter tip includes a suction tube 10, a top filtration section 20, a bottom filtration section 30, and a flavoring section 40.

[0042] The suction tube 10 has a suction channel 11 inside. The top of the suction tube 10 is used for suction, and the bottom of the suction tube 10 is detachably connected to the aerosol generating device. The top filter section 20 is located at the top of the suction channel 11. The bottom filter section 30 is located at the bottom of the suction channel 11. The aroma-enhancing section 40 is located inside the suction channel 11, between the top filter section 20 and the bottom filter section 30.

[0043] In the above embodiments, when a user needs to aspirate aerosols, the bottom of the suction tube 10 can be connected to the aerosol generating device, and the user can then aspirate aerosols from the top of the suction tube 10. After the single-use filter is used up, it can be removed from the aerosol generating device. When the user needs to aspirate aerosols again, a new single-use filter can be replaced. When not in use, the single-use filter is generally stored to avoid contact with air and contamination. For example, the single-use filter can be packaged in a protective bag for safe storage.

[0044] The single-use filter of this embodiment is detachably connected to the aerosol generating device via the bottom of the suction tube 10, allowing for single-use operation. This filter is ready to use immediately and is not exposed to air when not in use, ensuring cleanliness and hygiene during use, thus improving the user's inhalation experience. When the user inhales aerosol through the single-use filter, the aerosol enters the suction tube 10 from the bottom filtration section 30, where it undergoes initial filtration. The aerosol is then flavored by the aroma-enhancing section 40 and further filtered by the top filtration section 20 before being inhaled. During this process, condensate generated during the cooling process remains within the suction tube 10, while the aroma-enhancing section 40 adjusts the aerosol's flavor, further enhancing the user's inhalation experience. Furthermore, the single-use filter ensures that the aerosol is adequately filtered and flavored each time the user inhales, further improving the user's inhalation experience. Furthermore, when the disposable filter is discarded, it can remove the carbon deposits generated during the heating process of the aerosol generating matrix, thereby reducing carbon deposits and other sediments in the aerosol generating device, making it easier to keep the aerosol generating device clean, reducing the frequency of cleaning, and making it hygienic and environmentally friendly.

[0045] like Figure 1As shown, in some embodiments, the suction tube 10 includes a paper tube. The paper tube is a biodegradable material, and when the single-use filter is used as a disposable product, the paper tube suction tube 10 can reduce environmental pollution. Furthermore, its manufacturing cost is relatively low, which is beneficial for the mass production of single-use filters. The paper tube is non-toxic and odorless, ensuring user safety when it comes into contact with the user's mouth and the outer periphery of the suction tube 10. The hardness of the suction tube 10 is greater than that of the tobacco wrapping paper of traditional cigarettes. In the actual manufacturing of single-use filters, the top filter section 20, the bottom filter section 30, and the flavoring section 40 are filled into the suction tube 10, or the filling materials such as the flavoring section 40 and the filter section are surrounded by rolled paper to form a suction channel 11 for the user to inhale. Of course, in other embodiments, the suction tube 10 can also be replaced with other heat-resistant materials, such as glutinous rice paper or cornstarch-based plastic.

[0046] In some embodiments, the cross-sectional shape of the suction tube 10 along its length direction can be circular, square, flower-shaped, or other shapes, without limitation. Its cross-sectional shape can be changed according to specific process requirements and user needs, as long as it ensures that the aerosol can flow from the bottom to the top of the secondary-disposal filter. For example, the cross-sectional shape of the suction tube 10 can be determined based on the connection position between the aerosol generating device and the secondary-disposal filter.

[0047] In some embodiments, the cross-sectional dimensions of the suction tube 10 along its length direction can be varied according to specific process requirements and user needs, without limitation. For example, the outer dimensions of the suction tube 10 can be determined based on the connection position between the aerosol generating device and the secondary filter. Exemplarily, the paper tube is circular, and its outer diameter is adapted to the connection position between the aerosol generating device and the secondary filter to ensure a stable connection between the paper tube and the aerosol generating device, facilitating user operation.

[0048] like Figure 1 As shown, in some embodiments, the sidewall of the suction tube 10 is provided with a through hole 12, which communicates with the suction channel 11. The through hole 12 can be located at any position along the axial direction of the suction tube 10, but it needs to have a certain distance from the top of the suction tube 10 to avoid clogging the through hole 12 when the user is suctioning the secondary filter, thus affecting the entry of external air into the through hole 12. In this embodiment, the through hole 12 allows cooler external air to enter the suction channel 11 to mix with the higher-temperature aerosol, reducing the temperature of the aerosol in the suction tube 10 and preventing the aerosol from scalding the nozzle, thereby improving the user's suction experience. At the same time, at least under the obstruction of the bottom filter section 30, the condensate will be concentrated and retained in the secondary filter and will not enter the aerosol generating device, avoiding the condensate flowing into the aerosol generating device and causing pollution, thus facilitating the cleaning and use of the aerosol generating device. In this application, the diameter, number, and shape of the through hole 12 are not limited. In other embodiments, the through hole 12 may not be provided.

[0049] For example, at least two through holes 12 are provided, and the at least two through holes 12 are evenly spaced around the center of the suction tube 10. In this way, by connecting the suction tube 10 through at least two through holes 12, external air can be evenly introduced into the suction channel 11 to fully mix with the aerosol, thereby effectively reducing the temperature of the aerosol. For example, two through holes 12 are provided, and the two through holes 12 are respectively located on both sides of the suction tube 10 and arranged opposite to each other.

[0050] like Figure 1 As shown, in some embodiments, the suction channel 11 further includes at least one hollow section 50. The hollow section 50 is a cavity without a filling structure, which has a larger volume compared to other parts of the suction channel 11. When the aerosol flows to the hollow section 50, it exchanges heat with the cold air inside the hollow section 50, thereby cooling and condensing the aerosol and improving the user's suction experience. In this embodiment, the suction channel 11 may include only one hollow section 50, or it may include multiple hollow sections 50, for example, adjacent hollow sections 50 are separated by filling structures. Of course, in other embodiments, the hollow section 50 may not be provided; for example, the entire suction channel 11 may be filled with different filling structures, thus forming no cavity portion.

[0051] like Figure 1 As shown, in some embodiments, the bottom filter section 30 includes high-temperature silica gel, and the bottom filter section 30 has an air inlet 31 extending from the top to the bottom. During use, the bottom of the disposable filter is close to the heating position of the aerosol generating device, where the temperature is high. In this embodiment, the high-temperature silica gel is heat-resistant, thus preventing the bottom filter section 30 from burning due to excessive temperature, ensuring the safe and reliable use of the disposable filter. Simultaneously, the high-temperature silica gel is recyclable, making it environmentally friendly and facilitating the disposable use of the filter. Furthermore, when the aerosol enters the suction channel 11 through the bottom filter section 30, the aerosol can pass through the air inlet 31, while large particles in the aerosol can be intercepted and adsorbed by the bottom filter section 30. Therefore, the bottom filter section 30 can prevent large particles from entering the suction channel 11 and being drawn in by the user, improving the user's suction experience. Of course, the bottom filter section 30 can also be made of other heat-resistant and environmentally friendly materials, such as polytetrafluoroethylene, polyetheretherketone, or polyimide. In this application, the cross-sectional shape of the bottom filter section 30 is not limited, nor is the number of its air inlets 31 limited.

[0052] For example, multiple air inlets 31 are provided so that the aerosol can pass through the bottom filter section 30 evenly, allowing the aerosol to flow smoothly and improving the aerosol's effects in subsequent aroma enhancement, filtration, and cooling.

[0053] like Figure 1As shown, in some embodiments, the top filter section 20 includes filter cotton. The filter cotton can effectively adsorb large particles in the condensate and aerosol, preventing the user from inhaling large particles and improving the user's inhalation experience. Furthermore, since the top filter section 20 is close to the user's mouth, and the filter cotton is colorless and odorless, it will not produce a foreign body sensation when in contact with the user's mouth, thus further improving the user's inhalation experience. In addition, the filter cotton is also relatively environmentally friendly, facilitating the single-use of this disposable filter. Of course, in other embodiments, the top filter section 20 can also be other porous structures that are harmless to the human body, such as cellulose acetate, activated carbon, or other natural fibers.

[0054] like Figure 1 As shown, in some embodiments, the flavoring section 40 includes flavoring particles. When the aerosol flows through the flavoring section 40, the particles can pass through the gaps in the flavoring particles and come into full contact with them, thereby carrying out the aroma of the flavoring particles and adjusting the flavor of the aerosol, thus achieving flavoring of the aerosol. Furthermore, the flavoring particles can also promote the cooling of the aerosol, allowing some of the condensate to settle in the flavoring section 40. For example, the flavoring particles may include plant fiber particles adsorbed with tobacco flavorings. When the aerosol flows through the plant fiber particles, the heat carried by the aerosol can carry out the tobacco flavorings adsorbed in the plant fiber particles, thereby adjusting the flavor of the aerosol and achieving flavoring of the aerosol. Moreover, the plant fiber particles are biodegradable, possessing better environmental friendliness, facilitating the single-use of this disposable filter. Of course, in other embodiments, the flavor-enhancing section 40 includes a flavor-enhancing block with a porous structure to allow aerosol flow. When the aerosol passes through the pores of the flavor-enhancing block, it can carry out the aroma of the flavor-enhancing block to adjust the flavor of the aerosol and achieve flavoring of the aerosol.

[0055] like Figure 1As shown, in some embodiments, the single-use filter tip further includes a first support filter section 61, and the aroma-enhancing section 40 is disposed between the top filter section 20 and the first support filter section 61. The first support filter section 61 and the top filter section 20 can confine the aroma-enhancing section 40 within a specific area of ​​the suction channel 11, preventing particles of the aroma-enhancing section 40 from passing through the top filter section 20 and being inhaled by the user, thus affecting the user's suction experience, and preventing particles of the aroma-enhancing section 40 from passing through the first support filter section 61 and falling to other positions, affecting the aroma-enhancing effect. In this embodiment, the first support filter section 61 and the top filter section 20 can confine the aroma-enhancing section 40 to a position near the top of the suction tube 10. When the user uses the single-use filter tip, the aroma-enhancing section 40 is close to the user's mouth. When the aerosol passes through the aroma-enhancing section 40, the aroma it carries can quickly enter the user's mouth, thus improving the aroma-enhancing effect of the aerosol and improving the user's suction experience. Of course, in other embodiments, depending on the specific structure of the flavor-enhancing section 40, the first support filter section 61 may not be provided, and the flavor-enhancing section 40 may be limited only by the covering of the suction tube 10.

[0056] For example, the first support filter section 61 includes filter cotton. The filter cotton can effectively adsorb condensate and small particles, and while effectively supporting the flavor-enhancing section 40, it also allows aerosols to flow smoothly into the flavor-enhancing section 40. In addition, the filter cotton is environmentally friendly, facilitating the single-use of this disposable filter. Of course, in other embodiments, the first support filter section 61 can also be other filtration structures that are harmless to the human body, such as cellulose acetate, activated carbon, or other natural fibers.

[0057] like Figure 2 As shown, in some embodiments, the single-use filter tip further includes a second support filter section 62, and the aroma-enhancing section 40 is disposed between the bottom filter section 30 and the second support filter section 62. The second support filter section 62 and the bottom filter section 30 can confine the aroma-enhancing section 40 within a specific area of ​​the suction channel 11, preventing particles of the aroma-enhancing section 40 from passing through the bottom filter section 30 and falling into the aerosol generating device, and preventing particles of the aroma-enhancing section 40 from passing through the second support filter section 62 and falling to other locations, thus affecting the aroma-enhancing effect. In this embodiment, the second support filter section 62 and the bottom filter section 30 can confine the aroma-enhancing section 40 to a position near the bottom of the suction tube 10, where the temperature is higher, which can fully stimulate the aroma of the aroma-enhancing section 40, making the aroma more intense, and providing the user with a better suction experience when inhaling the aerosol. Of course, in other embodiments, depending on the specific structure of the aroma-enhancing section 40, the second support filter section 62 may not be provided, and the aroma-enhancing section 40 may be confined solely by the covering of the suction tube 10.

[0058] For example, the second support filter section 62 includes filter cotton. The filter cotton can effectively adsorb condensate and small particles, and while effectively supporting the flavor-enhancing section 40, it also allows aerosols to flow smoothly into the flavor-enhancing section 40. In addition, the filter cotton is environmentally friendly, facilitating the single-use of this disposable filter. Of course, in other embodiments, the second support filter section 62 can also be other filtration structures that are harmless to the human body, such as cellulose acetate, activated carbon, or other natural fibers.

[0059] like Figure 2 As shown, in some embodiments, the secondary filter tip further includes a mist-enhancing section 70, which is disposed within the suction channel 11 to increase mist. The mist-enhancing section 70 adsorbs a smoke-generating agent. When the aerosol passes through the mist-enhancing section 70, the heat carried by the aerosol can heat the smoke-generating agent within the mist-enhancing section 70 to generate smoke, increase the amount of smoke, and thus enhance the user's vaping experience.

[0060] For example, the mist-generating section 70 is made of a porous material, such as cotton, fiber, ceramic, etc. Aerosols can pass through the pores of the mist-generating section 70 and generate smoke to enhance the user's inhalation experience. The smoke-generating agent can be glycerin or propylene glycol.

[0061] like Figure 3 As shown, in some embodiments, the secondary filter tip further includes a first filter section 80, which is disposed within the suction channel 11 and located between the top filter section 20 and the bottom filter section 30. The first filter section 80 can further filter the aerosol flowing within the suction channel 11, so that large particles in the aerosol and condensate formed by the cooling of the aerosol are retained within the suction channel 11 and will not be sucked up by the user, thereby further improving the user's suction experience. In this application, more filter sections can be set as needed to improve the filtration effect, without limitation.

[0062] For example, the first filter section 80 includes ceramic particles. The ceramic particles can adsorb large particles, acidic gases, and heavy metal gases in the aerosol, thereby improving the taste of the aerosol inhaled by the user and ensuring a better user experience. In another example, the first filter section 80 includes activated carbon. Activated carbon can adsorb large particles, acidic gases, and heavy metal gases in the aerosol, thereby improving the taste of the aerosol inhaled by the user and ensuring a better user experience. This application is not limited; any structure with superior filtration effect can be applied to the first filter section 80.

[0063] like Figure 1As shown in Embodiment 1 of this application, the single-use filter includes a suction tube 10, a top filter section 20, a bottom filter section 30, a flavoring section 40, and a first support filter section 61. The top filter section 20, bottom filter section 30, flavoring section 40, and first support filter section 61 are disposed within a suction channel 11. The bottom filter section 30 is located at the bottom end of the suction channel 11, the top filter section 20 is located at the top end of the suction channel 11, the first support filter section 61 is located near the top filter section 20 in the suction channel 11, the flavoring section 40 is located in the space between the first support section and the top filter section 20, and a hollow section 50 is formed between the first support filter section 61 and the bottom filter section 30. A through hole 12 is provided on the side wall of the suction tube 10. The single-use filter provided in this embodiment has a simple structure and low cost. When users inhale aerosols through this single-use filter, they can inhale aerosols with a distinct and clean aroma, improving the user's inhalation experience.

[0064] like Figure 2 As shown in Embodiment 2 of this application, the single-use filter includes a suction tube 10, a top filter section 20, a bottom filter section 30, a flavoring section 40, a second support filter section 62, and a misting section 70. The top filter section 20, bottom filter section 30, flavoring section 40, second support filter section 62, and misting section 70 are disposed within a suction channel 11. The bottom filter section 30 is located at the bottom end of the suction channel 11, the top filter section 20 is located at the top end of the suction channel 11, the second support filter section 62 is located in the suction channel 11 near the bottom filter section 30, the flavoring section 40 is located in the space between the second support filter section 62 and the bottom filter section 30, the misting section 70 is adjacent to the top filter section 20, and a hollow section 50 is formed between the second support filter section 62 and the misting section 70. A through hole 12 is provided on the side wall of the suction tube 10. In this embodiment, when the user inhales the aerosol through the disposable filter, they can inhale an aerosol with a rich aroma and obvious smoke, which improves the user's inhalation experience.

[0065] like Figure 3As shown in Embodiment 3 of this application, the secondary filter includes a suction tube 10, a top filter section 20, a bottom filter section 30, a flavoring section 40, a first filter section 80, and a third support filter section 63, wherein the third support filter section 63 includes a porous high-temperature silicone. A top filter section 20, a bottom filter section 30, a flavoring section 40, a first filter section 80, and a third support filter section 63 are disposed within the suction channel 11. The bottom filter section 30 is located at the bottom end of the suction channel 11, the top filter section 20 is located at the top end of the suction channel 11, the flavoring section 40 is adjacent to the bottom filter section 30, the first filter section 80 is located between the top filter section 20 and the bottom filter section 30, and the third support filter section 63 is adjacent to the side of the first filter section 80 facing the bottom filter section 30. A hollow section 50 is formed between the third support filter section 63 and the flavoring section 40, and another hollow section 50 is formed between the first filter section 80 and the top filter section 20. The side wall of the suction tube 10 is provided with a through hole 12. In this embodiment, when the user inhales aerosol through this disposable filter, they can inhale aerosol with a rich aroma and sufficient filtration effect, improving the user's inhalation experience.

[0066] This application also provides an aerosol generating device, including a main unit and a secondary filter.

[0067] The secondary filter is detachably connected to the main unit. The main unit is equipped with a heating component that can heat the aerosol generation matrix to generate aerosols. The bottom end of the secondary filter is connected to the heating component, and the aerosols can enter the suction channel 11 from the bottom end of the secondary filter.

[0068] In the aerosol generating device of this application embodiment, the heating component heats the aerosol generating matrix to generate aerosol. The aerosol enters the suction channel 11 from the bottom of the single-use filter. The bottom filtration section 30 can perform preliminary filtration of the aerosol. The aerosol is then flavored by the aroma-enhancing section 40 and filtered again by the top filtration section 20 before being inhaled by the user. During this process, after the aerosol enters the suction tube, the condensate generated during the cooling process remains in the suction tube 10. At the same time, the aroma-enhancing section 40 can adjust the flavor of the aerosol, further improving the user's inhalation experience. Furthermore, since the single-use filter is disposable, it is not repeatedly consumed, thus ensuring that the aerosol is fully filtered and flavored each time the user inhales, thereby further improving the user's inhalation experience. Furthermore, when the disposable filter is discarded, it can remove the carbon deposits generated during the heating process of the aerosol generating matrix, thereby reducing carbon deposits and other sediments in the aerosol generating device, making it easier to keep the aerosol generating device clean, reducing the frequency of cleaning, and making it hygienic and environmentally friendly.

[0069] In some embodiments, the main unit has a mounting hole into which the secondary-use filter tip can be inserted for detachable connection. After insertion, the bottom end of the secondary-use filter tip connects to the heating element, allowing aerosol to enter the filter tip. After use, the user can remove the secondary-use filter tip from the mounting hole and replace it with a new one for the next use, ensuring clean and hygienic operation of the aerosol generator.

[0070] For example, the mounting hole and the periphery of the secondary filter are adapted to ensure that aerosol can only enter the secondary filter from the bottom end and will not escape from the periphery of the secondary filter, thus ensuring a good user experience.

[0071] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the content of this application's specification and drawings under the concept of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
