Technical Field

[0001] The embodiments of this application relate to the field of aerosol generation, and more particularly to a heated non-combustible appliance. Background Technology

[0002] Heated tobacco products (HTPs) generate smoke by heating an aerosol-generating matrix at low temperatures, preventing the tobacco from burning. The smoke produced in this way contains far fewer harmful components than that produced by ordinary cigarettes. Using HTPs can greatly avoid the adverse effects of cigarettes on the human body, making it a healthier way to smoke.

[0003] In related technologies, the number of uses of heated non-combustible appliances is limited per use, and there is a problem that the taste deteriorates quickly due to localized carbonization of the matrix. Utility Model Content

[0004] In view of this, the present application aims to provide a heated non-combustible appliance that can increase the number of suction ports and delay the decay of taste.

[0025] Heated tobacco products (HNB) are a new type of product designed as "low-temperature cigarettes" based on the concept of "heating without burning". Specifically, HNB devices can heat the aerosol-generating matrix segment containing the aerosol-generating matrix to a certain temperature at a low temperature, causing the aerosol-generating matrix segment to develop flavor, thereby achieving an inhalation effect close to that of real cigarettes.

[0026] Heated non-combustible appliances in related technologies use methods such as central heating or peripheral heating to heat the aerosol generation matrix section as a whole. Due to issues such as differences in tobacco density and heating uniformity, the number of puffs per use is often limited. Furthermore, it is easy to cause carbonization of the tobacco leaves in the later stages, resulting in a faster decline in the smoking taste and ultimately affecting the smoking experience.

[0027] To address the aforementioned problems, this application proposes a heated non-combustible appliance, referring to... Figure 1 and Figure 2 The heated non-combustible appliance of this application includes a housing 1, a first heating element 2 and a second heating element 3. The housing 1 has a first receiving cavity 11, a second receiving cavity 12 and a suction port 1a. The first receiving cavity 11 and the second receiving cavity 12 are both connected to the suction port 1a. The first heating element 2 is disposed in the first receiving cavity 11 and the second heating element 3 is disposed in the second receiving cavity 12. The first heating element 2 and the second heating element 3 are configured to have independently adjustable temperatures.

[0028] The specific structural form of the shell 1 is not limited. The shell 1 can form a cavity structure, and a partition wall can be provided inside the cavity to divide the cavity into a first receiving cavity 11 and a second receiving cavity 12. The first receiving cavity 11 and / or the second receiving cavity 12 can be formed by the partition wall and the shell 1 together, or it can be formed by the partition wall alone. The first receiving cavity 11 and the second receiving cavity 12 can be formed by independent partition walls, or they can share a part of the partition wall. In other words, a part of the partition wall can be formed as the cavity wall of both the first receiving cavity 11 and the second receiving cavity 12.

[0029] The shape, volume, or other specifications of the first receiving cavity 11 and the second receiving cavity 12 may be the same or different, and there are no restrictions on this.

[0030] Both the first receiving cavity 11 and the second receiving cavity 12 are used to contain the aerosol generation matrix. As an example, one of the first receiving cavity 11 and the second receiving cavity 12 can be used to contain a liquid aerosol generation matrix, and the other can contain a solid aerosol generation matrix. As another example, the first receiving cavity 11 and the second receiving cavity 12 are used to contain two aerosol generation matrices of different specifications, including but not limited to the matrix's density, shape, permeability, particle size, etc. As yet another example, the first receiving cavity 11 and the second receiving cavity 12 can also be used to contain the same aerosol generation matrix.

[0031] The aerosol generating matrix can be directly encapsulated within the first receiving cavity 11 and the second receiving cavity 12. Specifically, during the manufacturing process, openings communicating with the first receiving cavity 11 and the second receiving cavity 12 can be formed on the housing 1 first, then the aerosol generating matrix can be filled into the first receiving cavity 11 and the second receiving cavity 12, and then the openings of the housing 1 can be sealed. When the aerosol generating matrix is ​​exhausted, the entire heated non-combustible appliance is scrapped.

[0032] Alternatively, the housing 1 may have an installation port communicating with at least one of the first receiving cavity 11 and the second receiving cavity 12, through which the user can install the aerosol generating matrix into the first receiving cavity 11 and / or the second receiving cavity 12, thereby enabling the reuse of the heated non-combustible appliance.

[0033] The housing 1 also has a suction port 1a, which specifically refers to an opening for the user to inhale aerosol. The first receiving cavity 11 and the second receiving cavity 12 are both connected to the suction port 1a. In this way, the user can simultaneously inhale the aerosol generated by the aerosol generating matrix in the first receiving cavity 11 and the aerosol generated by the aerosol generating matrix in the second receiving cavity 12 through the suction port 1a.

[0034] The connection between the various cavities and openings mentioned here and below can be achieved by providing through holes at the corresponding positions of the housing 1, or by using airway components; there is no limitation on this.

[0035] The specific structural forms of the first heating element 2 and the second heating element 3 are not limited. The structures of the first heating element 2 and the second heating element 3 can be the same or different, and there is no restriction on this.

[0036] As an example, the first heating element 2 and / or the second heating element 3 may include one or more heating films that at least partially cover the inner wall surface of the corresponding receiving cavity, so that the first heating element 2 and / or the second heating element 3 can heat the aerosol generating matrix in a circumferential heating manner.

[0037] As another example, the first heating element 2 and / or the second heating element 3 may include one or more heating columns protruding from the inner wall of the corresponding receiving cavity. In actual use, the heating columns are inserted into the aerosol generating matrix, so that the first heating element 2 and / or the second heating element 3 can heat the aerosol generating matrix in a central heating manner.

[0038] Those skilled in the art can reasonably set the specific structural forms of the first heating element 2 and the second heating element 3 according to the specific heating requirements of the aerosol generation matrix actually contained in the first accommodating cavity 11 and the second accommodating cavity 12.

[0039] The first heating element 2 and the second heating element 3 are configured to have independently adjustable temperatures. Specifically, this means that the heating temperature of either the first heating element 2 or the second heating element 3 can change independently of the other. In other words, the heating temperatures of the first heating element 2 and the second heating element 3 are not correlated.

[0040] Taking the first heating element 2 and the second heating element 3 as an example of a resistance heating structure, the first heating element 2 and the second heating element 3 can be connected to two independent circuits respectively, and the current of the two circuits can be adjusted separately, so that the temperature of the first heating element 2 and the second heating element 3 can be adjusted independently.

[0041] The heated non-combustible appliance of this application embodiment is provided with two receiving cavities equipped with independent heating elements. Compared with the heated non-combustible appliances with single-cavity heating in the related art, the heated non-combustible appliance of this application embodiment can use different heating strategies to heat the aerosol generating matrix in the two receiving cavities separately. This helps to reduce the adverse effects caused by the density difference and thermal uniformity difference of different components in the aerosol generating matrix, increase the number of puffs per use, delay the decay of taste, and improve the smoking experience.

[0042] In some embodiments, further, refer to Figure 1 and Figure 2 The heated non-combustible appliance may also include a first temperature sensor 4 and a second temperature sensor 5, which are respectively disposed in the first receiving cavity 11 and the second receiving cavity 12. This facilitates precise control of the heating temperature of the first heating element 2 and the second heating element 3, thereby further increasing the number of sips per use and delaying the decay of the taste.

[0043] In some embodiments, specifically, one of the first receiving cavity 11 and the second receiving cavity 12 is used to receive a solid aerosol generating matrix, and the other is used to receive a liquid aerosol generating matrix.

[0044] Here, the solid aerosol generating matrix specifically refers to a solid matrix formed by a skeleton component and one or more combinations of binders, flavoring components, atomizing agents, and other functional components. As an example, the skeleton component can be a chemical, such as one or more combinations of cellulose, hemicellulose, and lignin; or it can be one or more combinations of powdered tobacco raw materials, tobacco fragments, tobacco stems, tobacco dust, and flavoring plants after crushing; or it can be a combination of chemicals and pulverized plant components. Furthermore, as an example, moisturizing components, such as glycerin and propylene glycol, can be added to the solid aerosol generating matrix to prevent excessive drying during heating, further reducing the probability of localized carbonization of the solid aerosol generating matrix.

[0045] There are no restrictions on the size and shape of the solid aerosol generation matrix, such as regular cylinders, trihedrons, tetrahedrons, or irregular three-dimensional structures.

[0046] In some embodiments, the solid aerosol generating matrix includes multiple extruded monomers. The extruded monomers are in any shape, such as strips, flakes, or granules. The multiple monomers can be arranged in an ordered manner within the solid aerosol generating matrix, or they can be arranged in a disordered manner within the solid aerosol generating matrix.

[0047] As an example, the solid aerosol generating matrix includes multiple strip-shaped extruded monomers.

[0048] In some embodiments, the same solid aerosol generating matrix may simultaneously include monomers of various shapes, such as strip-shaped monomers with different cross-sectional shapes, or at least two types of monomers selected from strip-shaped, sheet-shaped, and granular monomers.

[0049] In addition, the solid aerosol generating matrix may include one or more extruded monomers, as well as a matrix obtained by other molding methods, such as a matrix obtained by slurry method, sheet method, roll pressing method, natural tobacco leaf shredding method, etc., without limitation.

[0050] As an example, the solid aerosol generating matrix includes multiple strip-shaped extruded monomers, as well as multiple natural tobacco shreds.

[0051] Taking the multiple monomers constituting the solid aerosol generating matrix as an example, the methods of forming a solid aerosol generating matrix from multiple monomers include, but are not limited to, the following two: one is to cut the extruded strip monomers and then press or roll them by a machine to form a solid aerosol generating matrix, which is composed of multiple monomers arranged in a disordered manner; the other is to directly bundle the extruded strip monomers into a solid aerosol generating matrix by a machine, which is composed of multiple monomers arranged in an ordered manner.

[0052] Liquid aerosol generating matrix refers to a liquid matrix with atomizing agent as the main component. The atomizing agent mainly plays the role of generating aerosols. For example, the atomizing agent can be selected from one or more of the following: monohydric alcohol; dihydric alcohol; polyhydric alcohol; monocarboxylic acid, dicarboxylic acid, or esters formed by polycarboxylic acid and fatty alcohol. Depending on the taste and satisfaction requirements, a certain proportion of nicotine salts, flavorings, etc. can also be added to the liquid aerosol generating matrix.

[0053] In related technologies, the components in the aforementioned solid aerosol generating matrix and liquid aerosol generating matrix are usually mixed together to form an aerosol generating matrix and heated in the same heating chamber of a heated non-combustible appliance. This makes it difficult for the aforementioned components to reach a better heating temperature at the same time. For example, atomizing agent components usually require a higher heating temperature, which may cause components such as tobacco leaves to release at a faster rate, affecting the number of puffs. Furthermore, this heating temperature may cause components such as tobacco leaves to undergo local carbonization in the later stages of heating, resulting in a rapid decline in the puffing taste.

[0054] In this embodiment, the first receiving cavity 11 and the second receiving cavity 12 are used to receive the solid aerosol generating matrix and the liquid aerosol generating matrix, respectively. In this way, it is possible to use different heating strategies to heat the solid aerosol generating matrix and the liquid aerosol generating matrix, balance the release rate of each component and reduce the possibility of local carbonization of the components in the solid aerosol generating matrix, thereby further increasing the number of suction ports and delaying the decay of the suction taste, providing a better suction experience.

[0055] In some embodiments, specifically, taking the first accommodating cavity 11 for accommodating the solid aerosol generation matrix and the second accommodating cavity 12 for accommodating the liquid aerosol generation matrix as an example, the heating temperature of the first heating element 2 can be specifically set to 180℃-220℃.

[0056] The heating temperature range of the first heating element 2 is relatively lower than that of the heating temperature range of the single-chamber heating non-combustible appliance in the related art. That is, the heating non-combustible appliance in this embodiment is configured to use a "low temperature and slow heating" strategy to heat the solid aerosol generating matrix. This helps to further balance the release rate of the solid aerosol generating matrix and the liquid aerosol generating matrix, and helps to further reduce the possibility of local carbonization of the solid aerosol generating matrix. As a result, the number of suction ports is further increased and the decline in suction taste is delayed.

[0057] In the above embodiments, the heating temperature of the second heating element 3 is not limited.

[0058] In some embodiments, refer to Figure 1 and Figure 2 The housing 1 has a mixing chamber 13, and the first receiving chamber 11 and the second receiving chamber 12 are connected to the suction port 1a through the mixing chamber 13.

[0059] Here, the first receiving cavity 11 and the second receiving cavity 12 are connected to the suction port 1a through the mixing cavity 13. Specifically, the aerosol generated by the aerosol generating matrix in the first receiving cavity 11 and the aerosol generating matrix in the second receiving cavity 12 both need to pass through the mixing cavity 13 before they can reach the suction port 1a.

[0060] Similar to the first receiving cavity 11 and the second receiving cavity 12, the mixing cavity 13 can be formed by a partition wall disposed within the cavity of the housing 1. The specific shape of the mixing cavity 13 is not limited.

[0061] In this embodiment, the aerosol generated by the aerosol generating matrix in the first receiving cavity 11 and the aerosol generated by the aerosol generating matrix in the second receiving cavity 12 will be mixed in the mixing cavity 13 before reaching the suction port 1a, which helps to further improve the suction taste.

[0062] Of course, in some other embodiments, the housing 1 may not have a mixing chamber 13. For example, the first receiving chamber 11 and the second receiving chamber 12 may be independently connected to the suction port 1a.

[0063] Alternatively, one of the first receiving cavity 11 and the second receiving cavity 12 can be connected to the suction port 1a through the other. For example, the second receiving cavity 12 can be connected to the suction port 1a through the first receiving cavity 11. In other words, the aerosol generating matrix in the second receiving cavity 12 first flows to the first receiving cavity 11 and then flows to the suction port 1a. In this way, the aerosol generated by the aerosol generating matrix in the second receiving cavity 12 and the aerosol generated by the aerosol generating matrix in the first receiving cavity 11 can be mixed in the first receiving cavity 11. Furthermore, in this embodiment, the second receiving cavity 12 can be specifically configured to contain the liquid aerosol generating matrix, and the first receiving cavity 11 can be specifically configured to contain the solid aerosol generating matrix. In this way, the liquid aerosol generating matrix flowing into the first receiving cavity 11 will help to improve the release rate of the solid aerosol generating matrix, thereby further improving the suction taste.

[0064] In some embodiments, refer to Figure 1 The first receiving cavity 11 and the second receiving cavity 12 are respectively connected to the mixing cavity 13.

[0065] Here, the connection between the first receiving cavity 11 and the second receiving cavity 12 and the mixing cavity 13 specifically means that one of the first receiving cavity 11 and the second receiving cavity 12 can be connected to the mixing cavity 13 without the aid of the other. In other words, the aerosol generated by the aerosol generating matrix in the first receiving cavity 11 and the aerosol generated by the aerosol generating matrix in the second receiving cavity 12 can flow directly into the mixing cavity 13 without flowing through the other of the first receiving cavity 11 and the second receiving cavity 12.

[0066] As an example, the first receiving cavity 11 and the second receiving cavity 12 can be arranged side by side along the first direction, and the mixing cavity 13 can be arranged on one side of the first receiving cavity 11 and the second receiving cavity 12 along the second direction. The first direction intersects the second direction, and the first receiving cavity 11 and the second receiving cavity 12 can be connected to the mixing cavity 13 respectively through a three-way structure (e.g., a roughly Y-shaped pipe structure).

[0067] In this embodiment, the first receiving cavity 11 and the second receiving cavity 12 are respectively connected to the mixing cavity 13. This reduces the influence of aerosol flow on the temperature inside the first receiving cavity 11 and the second receiving cavity 12, that is, it reduces heat flow crosstalk between the first receiving cavity 11 and the second receiving cavity 12, thereby facilitating precise control of the heating temperature of the first receiving cavity 11 and the second receiving cavity 12.

[0068] In some embodiments, refer to Figure 2 One of the first receiving cavity 11 and the second receiving cavity 12 can also be connected to the mixing cavity 13 through the other of the first receiving cavity 11 and the second receiving cavity 12.

[0069] Here, "one of the first receiving cavity 11 and the second receiving cavity 12 is connected to the mixing cavity 13 through the other of the first receiving cavity 11 and the second receiving cavity 12" specifically means that only one of the first receiving cavity 11 and the second receiving cavity 12 is directly connected to the mixing cavity 13. For example, the first receiving cavity 11 is directly connected to the mixing cavity 13, while the other of the first receiving cavity 11 and the second receiving cavity 12, such as the second receiving cavity 12, is not directly connected to the mixing cavity 13, but can only be indirectly connected to the mixing cavity 13 through the first receiving cavity 11.

[0070] In this embodiment, the aerosol generated by the aerosol generating matrix in the first receiving cavity 11 and the aerosol generated by the aerosol generating matrix in the second receiving cavity 12 will be mixed in one of the first receiving cavity 11 and the second receiving cavity 12, and then enter the mixing cavity 13 for secondary mixing. This will help improve the uniformity of mixing, thereby improving the taste.

[0071] In some embodiments, specifically, referring to Figure 2 The second receiving cavity 12 is connected to the mixing cavity 13 through the first receiving cavity 11. The second receiving cavity 12 is used to receive the liquid aerosol generation matrix, the first receiving cavity 11 is used to receive the solid aerosol generation matrix, and the second receiving cavity 12 is used to receive the liquid aerosol generation matrix.

[0072] In this embodiment, the aerosols generated by the liquid aerosol generating matrix and the aerosols generated by the solid aerosol generating matrix will first be mixed in the first receiving cavity 11, and then flow together into the mixing cavity 13 for secondary mixing. This will help improve the mixing uniformity of the two. Furthermore, the flow of the aerosols generated by the liquid aerosol generating matrix into the first receiving cavity 11 will help improve the efficiency of the solid aerosol generating matrix releasing aerosols in the first receiving cavity 11.

[0073] In the embodiment described above where the mixing chamber 13 is provided, refer to Figure 1 The mixing chamber 13 can be configured as a spiral chamber.

[0074] As an example, the mixing cavity 13 can be formed by a spiral pipe-like partition wall, thereby forming a spiral cavity. It should be noted that in this embodiment, the mixing cavity 13 can be formed as a spiral cavity as a whole, or a portion of the cavity segment can be formed as a spiral cavity.

[0075] In this embodiment, by setting the mixing chamber 13 as a spiral chamber, the aerosol will change direction when flowing in the mixing chamber 13, thereby generating eddies and improving the mixing uniformity of the aerosol.

[0076] In some embodiments, refer to Figure 2The mixing cavity 13 can also be configured as a spherical cavity, a conical cavity, a cylindrical cavity, or an ellipsoidal cavity, etc.

[0077] In this embodiment, the mixing chamber 13 will have an arc-shaped cavity wall, which helps to guide the aerosol to generate a certain vortex, thereby improving the mixing uniformity. Compared with a spiral cavity, setting the mixing chamber 13 to the above shape will help reduce the manufacturing cost of the heated non-combustible appliance.

[0078] In some embodiments, refer to Figure 2 The heated non-combustible appliance may include a vortex generator 6, which is disposed in the mixing chamber 13.

[0079] Here, the vortex generator 6 specifically refers to a structure capable of guiding aerosols to generate vortices. As an example, the vortex generator 6 can be configured to guide aerosols to generate vortices through active action; for instance, the vortex generator 6 can be configured to actively rotate and / or actively vibrate (e.g., through a drive structure such as a motor). As another example, the vortex generator 6 can be configured to guide aerosols to generate vortices through passive action; for example, the vortex generator 6 may include a rotor rotatably disposed within the mixing chamber 13, with the rotor's rotation axis parallel to the aerosol flow direction within the mixing chamber 13, so that the aerosol flow will drive the rotor to rotate, thereby generating vortices. As yet another example, the vortex generator 6 may include one or more turbulence structures fixed within the mixing chamber 13, such as arc-shaped turbulence plates, turbulence columns protruding from the chamber wall of the mixing chamber 13, etc.

[0080] In this embodiment, by providing a vortex generator 6 in the mixing chamber 13, the mixing uniformity of the aerosol can be further improved.

[0081] In some embodiments, specifically, the volume of the mixing chamber 13 is set to 10-65 mL, such as any one or a point value between 10 mL, 15 mL, 20 mL, 25 mL, 30 mL, 35 mL, 40 mL, 45 mL, 50 mL, 55 mL, 60 mL, and 65 mL.

[0082] Setting the volume of the mixing chamber 13 to greater than or equal to 10 mL helps to achieve a better mixing effect, while setting it to less than or equal to 65 mL helps to shorten the distance that the aerosol reaches the suction port 1a and reduce the aerosol's taste decay during the mixing process.

[0083] In some embodiments, refer to Figure 1 and Figure 2The housing 1 has a first air inlet 1b and a second air inlet 1c. The first air inlet 1b connects the first receiving cavity 11 to the atmospheric environment, and the second air inlet 1c connects the second receiving cavity 12 to the atmospheric environment. The heating non-combustible appliance includes a first air inlet valve 7 disposed at the first air inlet 1b and a second air inlet valve 8 disposed at the second air inlet 1c.

[0084] The first intake valve 7 and / or the second intake valve 8 are configured to have an adjustable gas flow area, or the first intake valve 7 and the second intake valve 8 are configured to have different gas flow areas.

[0085] Here, "atmospheric environment" refers to the environment outside the casing 1. The gas flow area of ​​the first intake valve 7 and the second intake valve 8 specifically refers to the cross-sectional area of ​​the gas passage inside the first intake valve 7 and the second intake valve 8 perpendicular to the gas flow direction. The first intake valve 7 and the second intake valve 8 can be specifically configured as one-way valves to prevent aerosols from overflowing through the first intake valve 7 and the second intake valve 8.

[0086] The first air intake valve 7 and / or the second air intake valve 8 can be configured to have an adjustable gas flow area. In this way, the air intake volume of the first accommodating cavity 11 and / or the second accommodating cavity 12 can be flexibly adjusted per unit time during actual use. This balances the release efficiency of the aerosol generation matrix in the first accommodating cavity 11 and the second accommodating cavity 12, which can further increase the number of suction ports and delay the decay of taste.

[0087] Alternatively, the first air intake valve 7 and the second air intake valve 8 can be configured with different gas flow areas. In other words, the gas flow areas of the first air intake valve 7 and the second air intake valve 8 remain constant, but their gas flow areas are different. Thus, by balancing the release efficiency of the aerosol generation matrix in the first receiving cavity 11 and the second receiving cavity 12, the number of suction ports can be further increased and the decline in taste can be delayed.

[0088] In comparison, the adjustable gas flow area of ​​the first intake valve 7 and / or the second intake valve 8 further enhances the flexibility of adjustment. This is particularly true when the aerosol generating matrix filling the first and second receiving cavities 11 and 12 changes, allowing for readjustment of the air intake volume and thus improving the versatility of the heated non-combustible appliance. Furthermore, the air intake volume can be adjusted in real-time during actual suction, further increasing the number of puffs and improving the taste. The different gas flow areas of the first and second intake valves 7 and 8 also help reduce costs.

[0089] Of course, in some other embodiments, the first intake valve 7 and the second intake valve 8 can also be configured to have the same gas flow area.

[0090] In some embodiments, refer to Figure 3The housing 1 has a first mounting port 1d communicating with the first receiving cavity 11, and / or the housing 1 has a second mounting port 1e communicating with the second receiving cavity 12.

[0091] Here, the first mounting port 1d and the second mounting port 1e are used to fill the first receiving cavity 11 and the second receiving cavity 12 with the aerosol generating matrix.

[0092] In this embodiment, specifically, the first mounting port 1d and the second mounting port 1e are used to fill the first receiving cavity 11 and the second receiving cavity 12 with aerosol generating articles. The aerosol generating articles include a packaging shell 1 and an aerosol generating mechanism disposed in the packaging shell 1. Here, the packaging shell 1 can be specifically configured to have a structure made of high-temperature resistant thermally conductive material, such as a structure made of high-temperature resistant ceramic. The packaging shell 1 can be provided with vent holes for releasing aerosol. As an example, the vent hole diameter can be 0.1mm-0.5mm.

[0093] It should be noted that in this embodiment, the housing 1 may have only one of the first mounting port 1d and the second mounting port 1e, and the other of the first receiving cavity 11 and the second receiving cavity 12 may be configured to be pre-encapsulated with an aerosol generating matrix.

[0094] Furthermore, in this embodiment, referring to Figure 3 The heated non-combustible appliance may include a cover plate 9 movably connected to the housing 1, the cover plate 9 being used to open or close the first mounting port 1d and / or the second mounting port 1e.

[0095] In this embodiment, the housing 1 has a first mounting port 1d and / or a second mounting port 1e, which allows the user to replace the aerosol generating matrix in the first receiving cavity 11 and / or the second receiving cavity 12, thereby enabling the reuse of the heating non-combustible appliance, reducing costs and improving environmental performance.
