[0002] In a circumferentially heated non-combustible appliance, an aerosol product is installed inside a accommodating cavity, and a heating cylinder is arranged around the aerosol product.

In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.
[0026] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.
[0027] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).
[0028] This application discloses a heated non-combustible appliance that can simultaneously heat the center and circumference of an aerosol product 500 through electromagnetic induction heating during the preheating stage, thereby increasing the temperature rise rate of the aerosol product 500 during the preheating stage. This ensures that no large burnt smell is produced or reduces the burnt smell while shortening the preheating time of the heated non-combustible appliance.
[0029] Please refer to Figures 1 to 3 The heated non-combustible appliance includes an appliance body 100, a magnetic heating core 200, a magnetic heating cylinder 300, and an induction coil 400. The appliance body 100 has a receiving cavity 33, which extends in a first direction. One end of the receiving cavity 33 extending in the first direction is provided with an opening, and the other end is the bottom wall of the receiving cavity 33. The aerosol product 500 can be inserted into the receiving cavity 33 through the opening along the first direction.
[0030] The magnetic heating core 200 is installed on the appliance body 100. The magnetic heating core 200 extends in the first direction and penetrates the bottom wall of the accommodating cavity 33 in the first direction. The part of the magnetic heating core 200 outside the accommodating cavity 33 is installed on the appliance body 100, and the part of the magnetic heating core 200 inside the accommodating cavity 33 can penetrate into the aerosol product 500 during the insertion of the aerosol product 500 into the accommodating cavity 33.
[0031] The magnetic heating cylinder 300 is installed on the side wall of the accommodating cavity 33. The magnetic heating cylinder 300 is embedded in the outer or inner wall surface of the side wall of the accommodating cavity 33, or the magnetic heating cylinder 300 is integrally formed in the side wall of the accommodating cavity 33. The inner wall surface of the magnetic heating cylinder 300 can contact or adhere to the aerosol product 500 in the accommodating cavity 33; or the magnetic heating cylinder 300 does not directly contact the aerosol product 500, and only the side wall of the accommodating cavity 33 contacts the aerosol product 500.
[0032] An induction coil 400 is arranged around the accommodating cavity 33, and is located radially outside the magnetic heating cylinder 300. The extension direction of the induction coil 400 and the extension direction of the magnetic heating cylinder 300 are both in the first direction. When the induction coil 400 is energized, it can generate an alternating magnetic field that heats the magnetic heating core 200 and the magnetic heating cylinder 300. Thus, during the preheating stage of the non-combustible appliance, by passing an alternating current into the induction coil 400 to generate an alternating magnetic field, the magnetic heating core 200 can directly contact the aerosol matrix of the aerosol product 500. Currently, aerosol product 500 is heated by having the magnetic heating cylinder 300 directly or indirectly contact the outer peripheral surface of aerosol product 500. In this way, during the preheating stage, the magnetic heating core 200 and the magnetic heating cylinder 300 simultaneously heat the aerosol product 500 at its center and outer peripheral surface, which can improve the heating rate and efficiency of aerosol product 500. This can reduce or avoid the generation of a strong burnt smell while shortening the preheating time of aerosol product 500 by heating non-combustible appliances.
[0033] In some embodiments, the magnetic heating cylinder 300 may be made of 316 stainless steel. For different aerosol products 500, their temperatures gradually increase during the preheating stage, with the highest temperature at the end of the preheating stage being the temperature at which the preheating stage ends. The highest temperature during the preheating stage varies for different aerosol products 500; for example, the highest temperature during the preheating stage may be between 280°C and 360°C, or slightly beyond this range. To avoid a rapid heating rate of the aerosol product 500 after the preheating stage, which could negatively impact the user experience, the magnetic heating core 200 is provided with at least a first heating element. The Curie temperature of this first heating element can be equal to the highest temperature of the aerosol product 500 during the preheating stage, such as 360°C or 280°C. Thus, the first heating element in the magnetic heating core 200 loses its magnetism at the end of the preheating stage, and no longer heats the aerosol product 500 via electromagnetic induction after the preheating stage, effectively preventing an excessively rapid heating rate of the aerosol product 500 after the preheating stage.
[0034] Of course, in other embodiments, the Curie temperature of the first heating element can be set to be lower than the highest temperature of the heated non-combustible appliance during the preheating stage. For example, the temperature difference between the highest temperature of the heated non-combustible appliance during the preheating stage and the Curie temperature of the first heating element can be 40° to 60°. This temperature difference can be 40°, 50°, 55° or 60°. In this way, the first heating element loses its magnetism when the preheating stage is about to end. The first heating element only heats the aerosol product 500 by electromagnetic induction during the preheating process. This can also shorten the preheating time of the heated non-combustible appliance while avoiding the heating rate of the aerosol product 500 being too fast after the preheating stage.
[0035] In some embodiments, the magnetic heating core 200 is made of a composite soft magnetic material, such as a composite of two or more of 45 steel, 35 steel, cast iron, and SPCE (cold-rolled carbon steel). In addition to the first heating part, the magnetic heating core 200 also has a second heating part connected to or integrally formed with the first heating part. The Curie temperature of the first heating part can be equal to the highest temperature of the preheating stage, such as 360° or 280°. The Curie temperature of the second heating part can be greater than the highest temperature of the preheating stage, so as to ensure that the second heating part can heat the aerosol product 500 by electromagnetic induction, whether in the preheating stage or after the preheating stage. However, the heating rate and heating efficiency of the magnetic heating core 200 on the aerosol product 500 after the preheating stage are less than those on the aerosol product 500 during the preheating stage.
[0036] In some embodiments, the magnetic heating core 200 may be made of a single soft magnetic material, such as 45 steel, 35 steel, cast iron, or SPCE (cold-rolled carbon steel). The magnetic heating core 200 may have only a first heating part, which participates in heating the aerosol product 500 in the preheating stage only through electromagnetic induction heating. After the preheating stage, the first heating part loses its magnetism.
[0037] The magnetic heating cylinder 300 can be made of 316 stainless steel. The Curie temperature of the magnetic heating cylinder 300 is higher than the highest temperature of the non-combustible appliance during the preheating stage. The magnetic heating cylinder 300 not only heats the aerosol product 500 under an alternating magnetic field during the preheating stage, but also heats the aerosol product 500 through electromagnetic induction after the preheating stage to ensure the normal use of the aerosol product 500.
[0038] In some embodiments, the magnetic permeability of the magnetic heating cylinder 300 is less than that of the magnetic heating core 200. This ensures that the heating rate of the magnetic heating cylinder 300 is lower than that of the magnetic heating core 200 during the preheating of the aerosol product 500 by the heating non-combustible appliance. This guarantees that the magnetic heating cylinder 300 preheats the aerosol product 500 using a low-temperature baking method, reducing or even avoiding the burnt smell caused by over-baking of the packaging paper around the aerosol product 500, thus improving the user experience. The magnetic permeability of the magnetic heating core 200 is greater than that of the magnetic heating cylinder 300. During the preheating stage, the magnetic heating core 200 is the main heating source for the aerosol product 500. Throughout the heating stage, the magnetic heating core 200 primarily heats the aerosol product 500 during the preheating stage, playing a crucial role in shortening the preheating time.
[0039] In other embodiments, the magnetic permeability of the magnetic heating cylinder 300 can be set to be comparable to, or equal to or only slightly different from, the magnetic permeability of the magnetic heating core 200. As long as the heating rate and heating efficiency of the magnetic heating core 200 on the aerosol product 500 after the preheating stage are both less than those on the aerosol product 500 during the preheating stage, the purpose of shortening the preheating time can be achieved. Alternatively, as long as the magnetic heating cylinder 300 and the magnetic heating core 200 can simultaneously heat the aerosol product 500 through electromagnetic induction during the preheating stage, the preheating time can be shortened compared to the prior art which only uses circumferential heating.
[0040] In some embodiments, please refer to Figure 2 and Figure 3The extending direction of the accommodating cavity 33 is the same as the extending direction of the induction coil 400, and both extend in the first direction. The magnetic heating core 200 is located at the center of the magnetic heating cylinder 300. In order to avoid the magnetic heating cylinder 300 from forming a magnetic field shielding the magnetic heating core 200, the magnetic heating cylinder 300 and the magnetic heating core 200 are staggered in the first direction. In this way, the aerosol product 500 can be heated simultaneously by the magnetic heating core 200 and the magnetic heating cylinder 300 under the alternating magnetic field during the preheating stage.
[0041] Of course, in other embodiments, the magnetic heating cylinder 300 and the magnetic heating core 200 can also be arranged to partially overlap in the first direction. The magnetic heating cylinder 300 can form a magnetic field shield for the end of the magnetic heating core 200 facing the opening of the accommodating cavity 33, as long as the magnetic heating core 200 can generate heat in the alternating magnetic field during the preheating stage and can heat the aerosol product 500.
[0042] In some embodiments, please continue to refer to Figure 2 and Figure 3 The accommodating cavity 33, the induction coil 400, the magnetic heating cylinder 300 and the magnetic heating core 200 all extend in the first direction. In the radial direction of the magnetic heating cylinder 300, the magnetic heating core 200, the magnetic heating cylinder 300 and the induction coil 400 are arranged from the inside to the outside.
[0043] In the first direction, the induction coil 400 has a first sensing end 401 facing the opening of the accommodating cavity 33 and a second sensing end 402 facing away from the opening of the accommodating cavity 33. The magnetic heating cylinder 300 has a first heating end 301 facing the opening of the accommodating cavity 33 and a second heating end 302 facing away from the opening of the accommodating cavity 33. The second sensing end 402 of the induction coil 400 corresponds to the bottom wall of the accommodating cavity 33 in the first direction to ensure that the magnetic heating core 200 extending into the accommodating cavity 33 can be in a strong magnetic field. The first sensing end 401 of the induction coil 400 is located in the first direction at the bottom wall of the magnetic heating cylinder 300. On the side of the first heating end 301 away from the opening of the accommodating cavity 33, that is, in the structure where the first direction extends in the vertical direction, the first sensing end 401 is located below the first heating end 301. This can reduce the magnetic field strength of the first heating end 301 of the magnetic heating cylinder 300 under the alternating magnetic field, that is, reduce the temperature of the first heating end 301 of the magnetic heating cylinder 300. This avoids the temperature of the cooling section and the filter section located above the aerosol matrix section in the aerosol product 500 being too high, which can reduce the probability of the filter section being deformed by high temperature baking, and helps to ensure that the aerosol product 500 does not collapse or deform during the heating process.
[0044] Of course, in embodiments where the heating temperature of the magnetic heating cylinder 300 in the alternating magnetic field is low or the filter section of the aerosol product 500 is heat-resistant, the first sensing end 401 of the induction coil 400 may be configured to correspond to the first heating end 301 of the magnetic heating cylinder 300 in the first direction, or the first sensing end 401 may be located on the side of the first heating end 301 facing the opening of the accommodating cavity 33 in the first direction.
[0045] In some embodiments, please refer to Figure 2 and Figure 3 For the entire device body 100, the device body 100 includes a shell assembly 1 and a receiving cylinder 3. The shell assembly 1 has a mounting cavity 111 and a mounting port 121 communicating with the mounting cavity 111. The receiving cylinder 3 is located in the mounting cavity 111 and is connected to the shell assembly 1. The receiving cylinder 3 is a cylindrical structure with one end open and one end closed in a first direction. The receiving cavity 33 is located in the receiving cylinder 3. The opening of the receiving cylinder 3 forms the opening of the receiving cavity 33. The side wall of the receiving cylinder 3 forms the side wall of the receiving cavity 33. The bottom wall of the receiving cylinder 3 forms the bottom wall of the receiving cavity 33. After the receiving cylinder 3 is connected to the shell assembly 1, the opening of the receiving cylinder 3 corresponds to the mounting port 121 of the shell assembly 1. The end of the aerosol product 500 can pass through the mounting port 121 and the opening of the receiving cylinder 3 and be inserted into the receiving cavity 33.
[0046] In some embodiments, the accommodating cylinder 3 and the aerosol article 500 can be pulled out from the mounting port 121 of the outer casing assembly 1 under external force to facilitate the cleaning of residues within the accommodating cavity 33. Please refer to... Figure 2 and Figure 3 The outer shell assembly 1 includes a shell body 11 and a suction nozzle 12 detachable from the shell body 11. The mounting port 121 is located in the suction nozzle 12, and the shell body 11 and the suction nozzle 12 enclose each other to form a mounting cavity 111. The accommodating cylinder 3 is snapped together with the suction nozzle 12 via a snap-fit structure 123. The suction nozzle 12 has a mounting recess 122. The snap-fit structure 123 includes a hook 1231 disposed on the suction nozzle 12 and extending toward the mounting cavity 111 in a first direction. The end of the accommodating cylinder 3 near its opening in the first direction is located in the mounting recess 122. The snap-fit structure 123 also includes a protrusion 31 on the side wall of the accommodating cylinder 3. During the movement of the accommodating cylinder 3 toward the mounting recess 122 in the first direction, the protrusion 31 of the accommodating cylinder 3 can pass over the hook 1231 on the suction nozzle 12 and abut against the hook 1231 on the suction nozzle 12 in the first direction to prevent the accommodating cylinder 3 from coming out of the mounting recess 122. Thus, the snap-fit connection between the protrusion 31 on the accommodating cylinder 3 and the hook 1231 on the suction nozzle 12 is achieved.
[0047] The side wall of the accommodating cylinder 3 is also provided with a supporting structure 112 that abuts against the shell body 11 in the extending direction of the accommodating cylinder 3, that is, in the first direction, to restrict the separation of the accommodating cylinder 3 from the shell body 11. The supporting structure 112 includes a first protrusion 1121 provided on the shell body 11 and a second protrusion 32 on the side wall of the accommodating cylinder 3. Under the action of external force, the second protrusion 32 can pass over the first protrusion 1121 to install the accommodating cylinder 3 into the mounting cavity 111. When there is no external force, the first protrusion 1121 can abut against the second protrusion 32 in the first direction to restrict the accommodating cylinder 3 from coming out of the mounting cavity 111, that is, to restrict the separation of the accommodating cylinder 3 from the shell body 11.
[0048] After the aerosol product 500 is consumed, the user can pull the nozzle part 12 so that the second protrusion 32 passes over the first protrusion 1121 in the first direction, thereby separating the nozzle part 12, the container 3 and the aerosol product 500 as a whole from the shell body 11, so as to facilitate the cleaning of the residue in the container 3.
[0049] In some embodiments, the shell body 11 and the nozzle part 12 in the shell assembly 1 may be integrally formed or connected, and the accommodating cylinder 3 is fixed relative to the shell assembly 1. The accommodating cylinder 3 is not detachable and can be pulled out after the aerosol product 500 is consumed to remove the aerosol product 500 from the accommodating cavity 33.
[0050] In some embodiments, in order to reduce heat loss and improve heat utilization of the heating non-combustible appliance, the appliance body 100 is provided with a heat insulation cylinder 113 located in the mounting cavity 111, a receiving cylinder 3 is located in the heat insulation cylinder 113, the cylinder wall of the receiving cylinder 3 is arranged at intervals with the cylinder wall of the heat insulation cylinder 113, and the induction coil 400 is installed on the cylinder side wall of the heat insulation cylinder 113. The heat insulation cylinder 113 extends in the first direction and is a cylindrical structure with one end open and the other end closed in the first direction. The open end of the heat insulation cylinder 113 can be connected to the outer shell assembly 1 or integrally formed with the outer shell assembly 1. The receiving cylinder 3 is suspended in the heat insulation cylinder 113 and is connected to the outer shell assembly 1. The side wall of the heat insulation cylinder 113 is spaced apart from the side wall of the receiving cylinder 3, and the bottom wall of the heat insulation cylinder 113 is spaced apart from the bottom wall of the receiving cylinder 3. In this way, the heat transferred from the inside of the receiving cylinder 3 to the outside can be reduced through the heat insulation space between the wall of the receiving cylinder 3 and the wall of the heat insulation cylinder 113.
[0051] In some embodiments, please continue to refer to Figure 2 and Figure 3The heat insulation cylinder 113 can also be a cylindrical structure with openings at both ends in the first direction. One end of the heat insulation cylinder 113 is connected to or integrally formed with the shell body 11 of the outer shell assembly 1. The appliance body 100 also includes a connecting base 2 located in the mounting cavity 111. The connecting base 2 is sealed to the other end opening of the heat insulation cylinder 113. The side wall of the heat insulation cylinder 113 is spaced apart from the side wall of the accommodating cylinder 3. The connecting base 2 is spaced apart from the bottom wall of the accommodating cylinder 3 in the first direction. The magnetic heating core 200 is installed on the connecting base 2, and the magnetic heating core 200 passes through the bottom wall of the accommodating cylinder 3 and extends into the accommodating cavity 33.
[0052] Of course, in embodiments where the connecting base 2 is not provided, the magnetic heating core 200 can also be installed on the bottom wall of the heat insulation cylinder 113, or the magnetic heating core 200 can be installed on other components in the mounting cavity 111. The magnetic heating core 200 passes through the bottom wall of the heat insulation cylinder 113 and the bottom wall of the accommodating cylinder 3 and extends into the accommodating cavity 33.
[0053] In some embodiments, please continue to refer to Figure 2 and Figure 3 The magnetic heating core 200 is spaced apart from the bottom wall of the container cylinder 3 to form a connecting air passage 4 that communicates with the container cavity 33. The connecting air passage 4 can be an annular air passage surrounding the magnetic heating core 200. The appliance body 100 has an air inlet 13 and an air inlet passage 5. The air inlet 13 is located on the outer shell assembly 1 and communicates with the external space of the appliance body 100. The air inlet passage 5 is located between the heat insulation cylinder 113 and the container cylinder 3. The air inlet passage 5 is an annular air passage arranged around the container cylinder 3. The air inlet 13 can communicate with the connecting air passage 4 through the air inlet passage 5. External air can enter the appliance body 100 from the air inlet 13 and enter the container cavity 33 along the air inlet passage 5 and the connecting air passage 4 to supply air to the aerosol product 500.
[0054] In some embodiments, please continue to refer to Figure 2 and Figure 3 The air inlet 13 is located in the first direction on the side of the air intake passage 5 facing the opening of the receiving cavity 33. The air inlet 13 is located between the shell body 11 and the nozzle portion 12. At least a portion of the nozzle portion 12 is inserted into the opening of the shell body 11. There is a channel between the shell body 11 and the nozzle portion 12 in the first direction that connects the air inlet 13 and the air intake passage 5.
[0055] In some embodiments, the air inlet duct 5 of the device body 100 may also be provided on the connecting base 2, and the air inlet is connected to the accommodating cavity 33 through the air inlet duct 5 and the connecting duct 4. Alternatively, no connecting duct 4 is provided between the magnetic heating core 200 and the bottom wall of the accommodating cylinder 3, the magnetic heating core 200 is a hollow structure, and the air inlet duct 5 can be connected to the accommodating cavity 33 through the internal space of the magnetic heating core 200.

Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
