The heating component usually has two heating methods: direct contact heating and hot air flow heating.

[0028] In addition, the features, operations, or characteristics described in the specification can be combined in any appropriate manner to form various implementation manners, and the operation steps involved in each embodiment can also be reordered or adjusted in an obvious manner by those skilled in the art. Therefore, the specification and the drawings are only for clearly describing a certain embodiment and do not mean that they are essential components and / or sequences.

[0029] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meanings. The "connection" and "coupling" mentioned in the present application, unless otherwise specified, both include direct and indirect connections (couplings).

[0030] An embodiment of the present application discloses a heating component 1, which is applied to a non-combustion heating device and is used to heat an aerosol-forming substrate.

[0031] The heating component 1 disclosed in the embodiment of the present application, please refer to Figure 2 and Figure 3, including a heating housing 11 and a porous member 12. The heating housing 11 includes an air inlet section 111 and an air outlet section 113 arranged in a first direction. The heating housing 11 has a receiving cavity 116, and also has a gas inlet 112 and a gas outlet 115 communicating with the receiving cavity 116. The gas inlet 112 is located in the air inlet section 111, and the gas outlet 115 is located in the air outlet section 113. The outer shell wall of the air outlet section 113 is used to contact an aerosol generation substrate. The porous member 12 is fixed in the receiving cavity 116. The pores on the porous member 12 communicate the gas inlet 112 with the gas outlet 115. Gas can enter the receiving cavity 116 from the gas inlet 112, and then discharge from the gas outlet 115 along the pores on the porous member 12.

[0032] During the process of the heat of the heating housing 11 being transferred to the outside of the receiving cavity 116, the heat can be transferred to the aerosol generation substrate by direct contact through the contact between the outer shell wall of the air outlet section 113 of the heating housing 11 and the aerosol generation substrate. During the process of the heat of the heating housing 11 being transferred into the receiving cavity 116, the heating housing 11 first transfers the heat to the porous member 12. Since the air flow passes through the porous member 12, in this way, the heating housing 11 transfers the heat to the air flow passing through the porous member 12 through the porous member 12 to generate a hot air flow. The hot air flow directly enters the aerosol generation substrate after discharging from the gas outlet 115. In this way, the aerosol generation substrate can be heated by the hot air flow. Thus, during the process of the heat of the heating housing 11 being transferred to the inside and outside of the receiving cavity 116, heating of the aerosol generation substrate can be realized, which helps to improve the heat utilization rate of the entire heating assembly 1, reduce the heat loss of the heating assembly 1, and thus reduce the energy consumption of the heat-not-burn device.

[0033] Specifically, in one embodiment, please refer to Figure 2 and Figure 3 , the heating housing 11 is a heat generating element. The heating housing 11 can have magnetism. The material of the heating housing 11 includes SUS430 and / or cold-rolled carbon steel material for deep drawing. The heating assembly 1 needs to be used in cooperation with an induction coil 36 that can generate an alternating magnetic field. The heating housing 11 can generate heat in the alternating magnetic field to heat the aerosol generation substrate.

[0034] Or in other embodiments, the heating housing 11 is made of a conductive metal material. The heating housing 11 is electrically connected to an external power supply assembly. After the heating housing 11 is powered on, it can generate heat.

[0035] In one embodiment, please continue to refer to Figure 2 and Figure 3, the heating housing 11 is generally a cylindrical structure extending in the first direction. One end of the heating housing 11 in the first direction is an open end, and the other end is a closed end. The internal space of the heating housing 11 is the accommodation cavity 116 for installing the porous member 12; according to its position, the heating housing 11 can be divided into an air inlet section 111 and an air outlet section 113 in the first direction. The gas inlet 112 on the air inlet section 111 is used for cold air outside the heat-not-burn device to enter. After the external cold air is heated through the pores in the internal porous member 12, it is discharged from the gas outlet 115 on the air outlet section 113. The outer shell wall of the air outlet section 113 is arranged in contact with the aerosol-forming substrate, so that the hot air discharged from the gas outlet 115 directly enters the aerosol-forming substrate, realizing heating for the aerosol-forming substrate.

[0036] In one embodiment, the gas inlet 112 on the air inlet section 111 of the heating housing 11 can be arranged on the cylindrical side wall of the cylindrical structure of the heating housing 11, or in other embodiments, the open end of the heating housing 11 can also be used as the gas inlet 112 communicating with the accommodation cavity 116.

[0037] Of course, the gas outlet 115 on the air outlet section 113 of the heating housing 11 can be arranged on the cylindrical side wall of the cylindrical structure of the heating housing 11, or in other embodiments, it can also be arranged on the end face of the closed end of the heating housing 11.

[0038] In one embodiment, please continue to refer to Figure 2 and Figure 3 , the porous member 12 can be porous ceramic or porous metal. The porous member 12 can be fixed in the heating housing 11 by interference fit or gluing. There are multiple pores in the porous member 12, and the gas inlet 112 on the heating housing 11 can communicate with the gas outlet 115 through the multiple pores in the porous member 12.

[0039] In one embodiment, please continue to refer to Figure 2 and Figure 3 , the outer shell wall of the air outlet section 113 of the heating housing 11 is in contact with the aerosol-forming substrate. The heating housing 11 is a tubular structure with one end open and one end closed. The part of the heating housing 11 close to the closed end can be regarded as the air outlet section 113. The whole air outlet section 113 can be embedded in the aerosol-forming substrate. The end face of the closed end of the heating housing 11 and the outer peripheral surface of the part close to the closed end are both in contact with the aerosol-forming substrate, so as to increase the contact area between the aerosol-forming substrate and the heating housing 11, improve the heat utilization rate of the heating assembly 1, and further reduce the energy consumption of the heat-not-burn device.

[0040] Furthermore, in one embodiment, please continue to refer to Figure 2 and Figure 3, the air outlet section 113 can be set to have an insertion end 114 located at the end of the heating housing 11 in the first direction, that is, the closed end of the heating housing 11 is the insertion end 114. In order to facilitate the insertion of the heating housing 11 into the aerosol generating substrate, the insertion end 114 is set to be a tip, such as a conical end or a pyramidal end.

[0041] Furthermore, the gas outlet 115 is mainly arranged on the side wall of the housing of the heating housing 11. In one embodiment, the size of the air outlet section 113 in the first direction can also be increased, and a plurality of gas outlets 115 are provided. Two adjacent gas outlets 115 are arranged at intervals on the air outlet section 113. For example, a plurality of gas outlets 115 can be arranged at uniform intervals in the first direction and / or in the circumferential direction of the heating housing 11, or a plurality of gas outlets 115 can be arranged in a discrete manner on the side wall of the housing of the heating housing 11. In this way, the contact area between the porous member 12 and the cold air flow in the accommodation cavity 116 can be increased, thereby further improving the heat utilization rate of the heating assembly 1 and reducing the energy consumption of the heating assembly 1.

[0042] In another embodiment, only the end face of the closed end of the heating housing 11 can be set to contact the aerosol generating substrate. Then, the air outlet section 113 can be considered as the part of the heating housing 11 infinitely close to the end face of the closed end. The gas outlet 115 can be arranged only on the end face of the closed end of the heating housing 11. The hot air flow is directly discharged into the aerosol generating substrate from the gas outlet 115 on the end face, or the gas outlet 115 can also be arranged on the side wall of the housing of the heating housing 11. The hot air flow is discharged from the gas outlet 115 on the side wall of the housing into the accommodation cavity 321 and enters the aerosol generating substrate from the accommodation cavity 321. In this way, heating of the aerosol generating substrate can also be achieved by direct contact.

[0043] The embodiment of the present application also provides a heat-not-burn device. Please refer to Figure 1 and Figure 2 . The heat-not-burn device includes a device main body 3 and the heating assembly 1 in any of the above embodiments. The device main body 3 can be understood as the main frame structure of the heat-not-burn device. The device main body 3 has an accommodation cavity 321, an air inlet 34, and an air outlet 331. The accommodation cavity 321 is used to accommodate an aerosol generating substrate (not shown in the figure). The accommodation cavity 321 is communicated with the air outlet 331 to supply the aerosol generating substrate to be inserted into the accommodation cavity 321 from the air outlet 331.

[0044] The heating component 1 is installed on the device main body 3. The heating component 1 extends into the accommodating cavity 321 in the first direction, which can be understood as the insertion direction of the aerosol generation matrix or the extending direction of the accommodating cavity 321. The gas inlet 112 on the heating component 1 is communicated with the air inlet 34 to facilitate the entry of external cold air into the accommodating cavity 116 inside the heating component 1. The air outlet section 113 is located in the accommodating cavity 321 to facilitate the hot air flow from the gas outlet 115 on the air outlet section 113 to enter the aerosol generation matrix, thereby heating the aerosol generation matrix.

[0045] In one embodiment, please refer to Figure 2 , the device main body 3 has an installation cavity 35. Both the air inlet 34 and the air outlet 331 are communicated with the installation cavity 35. The device main body 3 includes a containing cylinder 32 installed in the installation cavity 35. The containing cylinder 32 is a cylindrical structure with one end open and one end closed. The open end of the containing cylinder 32 is communicated with the air outlet 331 of the device main body 3. The closed end of the containing cylinder 32 is located in the installation cavity 35. The position of the containing cylinder 32 can be positioned through the installation cavity 35 to improve the structural stability and reliability of the heat-not-burn device. The accommodating cavity 321 is located inside the containing cylinder 32. In this way, the cold air flow entering the device main body 3 from the air inlet 34 needs to pass through the installation cavity 35 and then enter the accommodating cavity 321, that is, the cold air flow needs to contact the wall of the containing cylinder 32. On the one hand, part of the cold air can be stored in the space inside the installation cavity 35. On the other hand, the cold air inside the installation cavity 35 can also be preheated by the outer wall of the containing cylinder 32 to improve the heat utilization rate of the heating component 1.

[0046] Specifically, the heating component 1 is installed on the device main body 3. The heating component 1 extends into the accommodating cavity 321 in the first direction. The air inlet section 111 on the heating housing 11 is communicated with the installation cavity 35 to facilitate receiving the cold air flow entering the heating component 1 from the air inlet 34 through the gas inlet 112. The air outlet section 113 is located in the accommodating cavity 321. In this way, the hot air flow heated by the porous member 12 can enter the accommodating cavity 321 from the gas outlet 115 on the air outlet section 113 to heat the aerosol generation matrix.

[0047] In other embodiments, the installation cavity 35 may not be provided in the device main body 3. Only the accommodating cavity 321 for accommodating the aerosol generation matrix may be provided in the device main body 3. The opening of the accommodating cavity 321 is the air outlet 331. The heating component 1 is installed on the device main body 3. The gas inlet 112 on the air inlet section 111 of the heating housing 11 in the heating component 1 is communicated with the air inlet 34. The air outlet section 113 of the heating housing 11 is located in the accommodating cavity 321. In this way, the air inlet 34 of the device main body 3 can be communicated with the accommodating cavity 321 through the heating component 1 to facilitate supplying hot air flow into the accommodating cavity 321 through the heating component 1. Such a setting helps to simplify the structure of the entire heat-not-burn device.

[0048] Please continue to refer to Figure 2 , in the embodiment where the installation cavity 35 is provided in the device main body 3, the heat-not-burn device adopts a side air intake method. The air intake port 34 corresponds to the accommodation cavity 321 in the extending direction of the accommodation cylinder 32, and the air intake port 34 is located radially outside the accommodation cylinder 32 in the radial direction of the accommodation cylinder 32.

[0049] An air flow channel 351 is provided in the device main body 3. The air flow channel 351 is located in the installation cavity 35, and the air flow channel 351 communicates the air intake port 34 with the gas inlet 112 on the heating component 1. In one embodiment, the accommodation cylinder 32 is a cylindrical structure. The air flow channel 351 includes an annular channel 3511 arranged around the accommodation cylinder 32. The outer cylindrical wall of the accommodation cylinder 32 encloses to form the channel wall of the annular channel 3511. The air intake port 34 is located on the side of the annular channel 3511 facing the air outlet 331 in the extending direction of the accommodation cylinder 32, and the air intake port 34 is located on the cavity wall of the installation cavity 35. In another embodiment, a part of the cylindrical side wall of the accommodation cylinder 32 is in contact with the cavity wall of the installation cavity 35. The annular channel 3511 is not provided in the air flow channel 351, and the air flow channel 351 is located between the cylindrical side wall of the accommodation cylinder 32 and the cavity wall of the installation cavity 35.

[0050] In this way, the air flow channel is arranged radially outside the accommodation cylinder 32, and the structure that the cylindrical side wall of the accommodation cylinder 32 forms the channel wall of the air flow channel 351 can utilize the heat transferred from the heating component 1 to the accommodation cylinder 32 to heat the air flow flowing through the air flow channel 351, so as to improve the heat utilization rate of the heating component 1 and the entire heat-not-burn device, and reduce the energy consumption of the heat-not-burn device.

[0051] In other embodiments, it is also possible to set that the air flow channel 351 is located on the side of the accommodation cavity 321 facing away from the air outlet 331 in the axial direction of the accommodation cylinder 32, and the air intake port 34 is located on the side of the air flow channel 351 facing away from the accommodation cavity 321 in the axial direction of the accommodation cylinder 32. Correspondingly, one end opening of the cylindrical structure on the heating housing 11 can be used as the gas inlet 112 of the heating housing 11 to facilitate the connection of the air flow channel 351 between the air intake port 34 and the gas inlet 112. Or in other embodiments, the position of the air flow channel is not limited, as long as the cold air entering the heat-not-burn device from the air intake port 34 passes through the gas inlet 112 and enters the heating component 1 before entering the accommodation cavity 321 and is heated by the heating component 1.

[0052] In one embodiment, please continue to refer to Figure 2, the accommodating cylinder 32 is arranged to be suspended in the installation cavity 35, and the bottom wall of the accommodating cylinder 32 is spaced from the cavity wall of the installation cavity 35. The heating assembly 1 can pass through the bottom wall of the accommodating cylinder 32 and extend into the accommodating cavity 321; in an embodiment where the bottom wall of the accommodating cylinder 32 is in contact with the cavity wall of the installation cavity 35, the heating assembly 1 can pass through the side wall of the accommodating cylinder 32 and extend into the accommodating cavity 321 to ensure that the gas inlet 112 of the heating housing 11 communicates with the air inlet 34 through the air flow channel 351.

[0053] In an embodiment where the accommodating cylinder 32 is suspended in the installation cavity 35 and the heating assembly 1 passes through the bottom wall of the accommodating cylinder 32 and extends into the accommodating cavity 321, please refer to Figure 2 , the bottom wall of the accommodating cylinder 32 also forms the channel wall of the air flow channel 351. In addition to the annular channel 3511, the air flow channel 351 further includes a bottom channel 3512 located between the bottom wall of the accommodating cylinder 32 and the cavity wall of the installation cavity 35. The air flow entering the annular channel 3511 from the air inlet 34 flows towards the bottom wall of the accommodating cylinder 32 and into the bottom channel 3512, enters the porous member 12 through the gas inlet 112 on the heating housing 11, is heated by the porous member 12, and then enters the aerosol generation matrix from the gas outlet 115 on the heating housing 11; the part of the heating housing 11 located in the bottom channel 3512 is the air inlet section 111 of the heating housing 11, and the part of the heating housing 11 extending into the accommodating cavity 321 is the air outlet section 113 of the heating housing 11.

[0054] In this way, the cold air entering the heat-not-burn device passes through the bottom wall of the accommodating cylinder 32, and the heat transferred by the heating assembly 1 to the bottom wall of the accommodating cylinder 32 can also be used to preheat the cold air flow, so as to improve the heat utilization rate of the heating assembly 1.

[0055] In one embodiment, please continue to refer to Figure 1 and Figure 2 , the device body 3 includes a mouthpiece 33 and a main body assembly 31. The air outlet 331 is arranged on the mouthpiece 33, and the aerosol generation matrix can be inserted into the accommodating cavity 321 along the air outlet 331 on the mouthpiece 33. The mouthpiece 33 is not the part that contacts the user's mouth during the use of the heat-not-burn device. The mouthpiece 33 only provides an entrance for the aerosol generation matrix to be inserted into the accommodating cavity 321; the main body assembly 31 has a concave portion 313. The mouthpiece 33 and the main body assembly 31 can be connected by a snap or a thread. The mouthpiece 33 covers the notch of the concave portion 313 so that the mouthpiece 33 and the main body assembly 31 enclose to form the installation cavity 35.

[0056] In other embodiments, the concave portion 313 can also be provided on the nozzle member 33. After the nozzle member 33 is connected to the main body assembly 31, the main body assembly 31 covers the notch of the concave portion 313 on the nozzle member 33 so that the nozzle member 33 and the main body assembly 31 enclose an installation cavity 35.

[0057] In some embodiments, please refer to Figure 2 , for the convenience of machining the air inlet 34, the air inlet 34 is provided between the nozzle member 33 and the main body assembly 31, so that the air inlet 34 is formed by the enclosure of the nozzle member 33 and the main body assembly 31. Specifically, by providing a concave portion on the nozzle member 33 and / or the main body assembly 31, after the nozzle member 33 is connected to the main body assembly 31, the nozzle member 33 and the main body assembly 31 enclose an air inlet 34 communicating with the installation cavity 35 at the concave portion.

[0058] In other embodiments, the air inlet 34 can also be provided on the barrel wall of the accommodating cylinder 32, or can also be provided on the main body assembly 31 or the nozzle member 33. The air inlet 34 can be machined by opening holes on the barrel wall of the accommodating cylinder 32, the cavity wall of the installation cavity 35 in the main body assembly 31 or the cavity wall of the installation cavity 35 on the nozzle member 33.

[0059] In one embodiment, please continue to refer to Figure 2 , the accommodating cylinder 32 is installed in the installation cavity 35.

During the connection process of the nozzle member 33 and the main body assembly 31, the part of the accommodating cylinder 32 near the bottom wall of the barrel is placed in the concave portion 313. After the nozzle member 33 is connected to the main body assembly 31, the installation and fixation of the accommodating cylinder 32 in the installation cavity 35 are achieved.

[0060] Of course, the accommodating cylinder 32 can also be connected to the cavity wall of the installation cavity 35 on the main body assembly 31 by a buckle, or an outer flange is provided on the accommodating cylinder 32, and the outer flange is clamped between the nozzle member 33 and the main body assembly 31 in the extending direction of the accommodating cylinder 32 to achieve the fixation of the accommodating cylinder 32 in the installation cavity 35, or the accommodating cylinder 32 is press-fitted between the nozzle member 33 and the main body assembly 31 in its length direction, and the bottom wall of the barrel of the accommodating cylinder 32 can be attached to the main body assembly 31.

[0061] Please continue to refer to Figure 2, in an embodiment where the nozzle member 33 and the receiving cylinder 32 are connected by snap-fitting, a first convex portion 3113 can be provided on the cavity wall of the installation cavity 35 on the main body assembly 31, and a second convex portion 322 is provided on the side wall of the receiving cylinder 32. The second convex portion 322 extends toward the radially outer side of the receiving cylinder 32. During the connection process of the nozzle member 33 and the main body assembly 31, the second convex portion 322 of the receiving cylinder 32 crosses over the first convex portion 3113 on the main body assembly 31 in the extending direction of the receiving cylinder 32. After the nozzle member 33 and the main body assembly 31 are connected in place, the first convex portion 3113 and the second convex portion 322 abut against each other in the extending direction of the receiving cylinder 32. Combining with the snap structure between the nozzle member 33 and the receiving cylinder 32, it is possible to limit the shaking of the receiving cylinder 32 in the installation cavity 35 in the extending direction of the receiving cylinder 32, which helps to improve the structural stability of the heat-not-burn device.

[0062] Of course, in an embodiment where the nozzle member 33 and the receiving cylinder 32 are connected by threads, the second convex portion 322 on the receiving cylinder 32 and the first convex portion 3113 on the main body assembly 31 can also be omitted.

[0063] In one embodiment, the main body assembly 31 includes a housing 311 and a support 312. The housing 311 has a cavity 3111 and an opening communicating with the cavity 3111. The support 312 is located in the cavity 3111 of the housing 311. The support 312 is fixed on the inner side wall of the housing 311. The support 312 is hermetically connected to the housing 311. The support 312 and the housing 311 enclose an inner concave portion 313 at the opening of the housing 311. The heating assembly 1 is installed on the support 312, and the heating assembly 1 extends toward the inner concave portion 313.

[0064] Specifically, a cylindrical structure 3112 extending toward the inner cavity 3111 of the housing 311 can be provided on the housing 311 at the opening of the housing 311. The support 312 in the cavity 3111 is hermetically inserted into the cylindrical structure 3112, so that the housing 311, the cylindrical structure 3112, and the support 312 enclose an inner concave portion 313 at the opening of the housing 311. The first convex portion 3113 is provided on the cylindrical structure 3112.

[0065] Of course, in other embodiments, the cylindrical structure 3112 can also be provided on the support 312, so that the cylindrical structure 3112 is hermetically fitted with the housing 311 at the opening of the housing 311, so that the housing 311, the cylindrical structure 3112, and the support 312 enclose an inner concave portion 313.

[0066] In one embodiment, please continue to refer to Figure 2 , in the heating assembly 1, the heating housing 11 has magnetism, and the material of the heating housing 11 includes magnetic material, so that the heating housing 11 can generate heat in an alternating magnetic field.

[0067] The heating assembly 1 is configured with an induction coil 36 arranged around the accommodation cavity 321. The induction coil 36 can be wound around the cylindrical structure 3112, or the induction coil 36 can also be wound around the cylindrical side wall of the accommodation cylinder 32. After the induction coil 36 is energized, an alternating magnetic field can be generated at the position where the heating housing 11 is located to ensure that the heating housing 11 generates heat.

[0068] In other embodiments, the heating assembly 1 is not configured with an induction coil 36, and the heating housing 11 in the heating assembly 1 uses a resistance heating method to realize heating for the aerosol generation matrix.
