[0002] The heated non-combustible device includes a main body and an atomizing component installed in the main body. The atomizing component has a accommodating cavity for containing aerosol products. The accommodating cavity is connected to the aerosol outlet on the main body through an atomizing channel.

[0013] The heating assembly has an outwardly protruding portion extending away from the accommodating cavity, and the heat insulation cylinder has a support structure extending toward the cavity. The outwardly protruding portion is clamped between the support structure and the first connector in the direction of extension of the atomization channel.

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.

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.

[0028] 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.

[0029] 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).

[0030] This application discloses an atomizing component, which is used in a heated non-combustible device to heat the aerosol product 7 and discharge the aerosol generated after heating.

[0031] Please refer to the atomizing component disclosed in the embodiments of this application. Figure 3 and Figure 4The device includes an atomizing body 1, a heating component 2, and a coil 3. The atomizing body 1 has an atomizing channel 11 for communicating with the aerosol outlet 411 of the device body 4. The atomizing channel 11 allows the aerosol generated after heating to flow out from the aerosol outlet 411 of the device body 4. The heating component 2 is installed in the atomizing body 1 and has a receiving cavity 216 communicating with the atomizing channel 11. The opening of the receiving cavity 216 communicates with one end opening of the atomizing channel 11, and the other end opening of the atomizing channel 11 communicates with the aerosol outlet 411 of the atomizing body 1. The receiving cavity 216 is used to accommodate an aerosol product 7, which can be inserted into the receiving cavity 216 from the aerosol outlet 411 of the device body 4 along the atomizing channel 11.

[0032] The heating component 2 is suspended in the atomizing body 1. The heating component 2 has a suspension end 217 in the extension direction of the atomizing channel 11 that is away from the aerosol outlet 411. The suspension end 217 is arranged at intervals from the atomizing body 1. In this way, most of the heat of the heating component 2 is transferred in the direction of the aerosol outlet 411 in the extension direction of the atomizing channel 11, that is, in the direction of the aerosol product 7 inside the accommodating cavity 216. This can reduce the heat transferred by the heating component 2 away from the aerosol product 7 to the atomizing body 1 in the extension direction of the atomizing channel 11, which helps to reduce heat loss, improve the heat utilization rate of the heating component 2, and thus reduce the energy consumption of the atomizing component.

[0033] The coil 3 is used to generate an alternating magnetic field, and the heating component 2 is used to inductively couple the coil 3 to generate heat in the alternating magnetic field. The coil 3 is arranged on the side of the heating component 2 away from the aerosol outlet 411 in the extension direction of the atomization channel 11. In this way, the electromagnetic heating method is adopted, and there is no need to set an external wire on the heating component 2. This avoids the current transmission on the external wire, which would lead to an increase in energy consumption, thereby further reducing the energy consumption of the atomization component.

[0034] In one embodiment, the coil 3 can be mounted on the end face of the suspension end 217 of the heating component 2 via a snap-fit ​​structure. The coil 3 has an insulating layer on the outside or the part of the heating component 2 that contacts the coil 3 is made of insulating material. This helps to reduce the distance between the heating component 2 and the coil 3. Under the condition of reaching the same heating temperature, this helps to improve the efficiency of converting magnetic field energy into electrical energy, thereby reducing the energy consumption of the entire atomizing component.

[0035] In one embodiment, please refer to Figure 3 and Figure 4The coil 3 can also be arranged at intervals with the heating component 2 in the extension direction of the atomization channel 11. For example, the atomization body 1 can be provided with a support surface perpendicular to the extension direction of the atomization channel 11, and the coil 3 can be supported and installed on the support surface of the atomization body 1 to realize the installation and fixation of the coil 3 in the atomization component; or in other embodiments, the coil 3 can also be pasted on the end face of the suspension end 217 of the heating component 2 by a certain thickness of adhesive layer, so that the coil 3 and the end face of the suspension end 217 are arranged at intervals, so that the heating component 2 with conductive properties is insulated from the coil 3, which can avoid the need to set an insulating layer on the coil 3 or the heating component 2 to insulate the coil 3 from the heating component 2. This can also reduce the distance between the heating component 2 and the coil 3 and improve the efficiency of converting magnetic field energy into electrical energy.

[0036] In one embodiment, please refer to Figure 4 , Figure 5 and Figure 6 The coil 3 is wound in a plane perpendicular to the extension direction of the atomizing channel 11. The coil 3 is a planar coil structure, which can be a circular coil structure, or in other embodiments, a polygonal or elliptical structure. The coil 3 has an inner coil and an outer coil. In the circular coil structure, the winding radius of the inner coil is smaller than that of the outer coil. In other coil structures, the winding size of the inner coil is smaller than that of the outer coil.

[0037] In other embodiments, in order to adapt to the structure of the support surface on the atomizing body 1, the coil 3 can also be set as a conical structure, and the inner and outer rings of the coil 3 can be arranged at intervals in the extension direction of the atomizing channel 11.

[0038] In one embodiment, the winding wire in coil 3 can be a wire with a circular cross-section. Of course, in other embodiments, the winding wire can also be a flat strip wire, which is wound in its thickness direction to form the entire coil structure.

[0039] In some embodiments, please refer to Figure 3 and Figure 4 For the atomizing body 1, the atomizing body 1 has a cavity, the atomizing component has an opening communicating with the cavity, the heating component 2 can be installed at the opening of the cavity, the suspension end 217 of the heating component 2 is located inside the cavity, the heating component 2 and the atomizing body 1 can be enclosed in the cavity to form a heat insulation cavity 12 arranged around the heating component 2, the heat insulation cavity 12 can reduce the heat transfer of the heating component 2 to the outside of the receiving cavity 216, thus reducing the heat loss of the heating component 2 and helping to reduce the energy consumption of the atomizing component.

[0040] In other embodiments, the atomizing body 1 does not have a cavity, and the atomizing body 1 only has an opening for installing the heating component 2. The heating component 2 can be suspended on the atomizing body 1 through the edge of the opening.

[0041] In one embodiment, the suspension end 217 of the heating component 2 is suspended within the cavity of the atomizing body 1. Please refer to [link / reference needed]. Figure 3 and Figure 4 The atomizing body 1 includes a heat insulation cylinder 13, a first connector 14, and a second connector 15. The heat insulation cylinder 13 has openings at both ends in the extension direction of the atomizing channel 11. The first connector 14 is located on the side of the second connector 15 facing the aerosol outlet 411 in the extension direction of the atomizing channel 11. The first connector 14 has an opening, and the atomizing channel 11 is located inside the opening of the first connector 14. The first connector 14 is an annular structure arranged around the atomizing channel 11. The first connector 14 and the second connector 15 are respectively sealed and fitted with the openings at both ends of the heat insulation cylinder 13 to enclose and form a cavity in the atomizing body 1. The opening on the first connector 14 forms the opening of the cavity.

[0042] The heating component 2 has an outwardly protruding portion 215 extending away from the accommodating cavity 216 in a plane extending perpendicular to the atomization channel 11. The outwardly protruding portion 215 can be an outwardly protruding annular structure. The outwardly protruding portion 215 is located at the end of the heating component 2 facing away from the coil 3 in the atomization channel 11 extension direction. Alternatively, the outwardly protruding portion 215 can also be spaced apart from the end of the heating component 2 facing away from the coil 3 in the atomization channel 11 extension direction. The heat insulation cylinder 13 has a support structure 131 extending toward the cavity. The support structure 131 can be connected to the inner wall 211 of the heat insulation cylinder 13. The cantilever arm has a first connector 14 having an extension portion 141 extending into the heat insulation cylinder 13 in the extension direction of the atomization channel 11. The outer protrusion 215 of the heating component 2 is clamped between the support structure 131 and the extension portion 141 in the extension direction of the atomization channel 11 to realize the installation and fixation of the heating component 2 on the atomization body 1. The heating component 2 is arranged at intervals between itself and the inner wall of the heat insulation cylinder 13, so that the heat insulation cylinder 13, the first connector 14, the second connector 15 and the heating component 2 surround the heat insulation cavity 12 arranged around the heating component 2 in the cavity.

[0043] The coil 3 is located inside the heat insulation cavity 12. The second connector 15 forms a support surface for the coil 3 on the end face of the heating component 2 in the extension direction of the atomization channel 11. The second connector 15 is provided with a wire hole (not shown in the figure). The coil 3 can be electrically connected to the battery 5 in the heating non-combustion device through the external wire (not shown in the figure) in the wire hole. The structure of the atomizing body 1 arranged in this way facilitates the assembly of the entire atomization component and the installation of the coil 3 in the atomization component.

[0044] In another embodiment, the heat insulation cylinder 13 can be configured as a structure with one end open and the other end closed. The atomizing body 1 does not have a second connector 15. The heat insulation cylinder 13, the first connector 14 and the heating component 2 are arranged to form a heat insulation cavity 12. The heat insulation cylinder 13 has a side cylinder wall arranged around the heating component 2, and also has a bottom cylinder wall that is spaced apart from the heating component 2 in the extension direction of the atomizing channel 11. The inner wall surface of the bottom cylinder wall can form a support surface for the support coil 3.

[0045] In other embodiments, the coil 3 can also be disposed outside the heat insulation cavity 12. For example, the coil 3 can be installed on the second connector 15 by means of a snap or by adhesive, or connected to the outer side of the bottom wall of the heat insulation cylinder 13. The heat insulation cylinder 13 or the second connector 15 are both made of plastic material to avoid the heat insulation cylinder 13 or the second connector 15 affecting the alternating magnetic field generated after the coil 3 is energized. Furthermore, disposing the coil 3 outside the heat insulation cavity 12 avoids the need to set a wire hole on the cavity wall of the heat insulation cavity 12, which helps to ensure the sealing performance of the heat insulation cavity 12, thereby further reducing heat loss and energy consumption.

[0046] In some embodiments, please refer to Figure 3 and Figure 4 The atomizing component has an air inlet channel 218 and an air inlet chamber 219. The air inlet chamber 219 is located on the side of the accommodating cavity 216 away from the aerosol outlet 411 in the extension direction of the atomizing channel 11, or is used to be disposed between the aerosol product 7 and the bottom wall of the accommodating cavity 216. The air inlet channel 218 is used to be disposed on the radial outer side of the aerosol product 7 and is used to communicate with the aerosol outlet 411 of the device body 4. The air inlet channel 218 can communicate with the accommodating cavity 216 through the air inlet chamber 219. In this way, the atomizing component forms a top air inlet structure. The air inlet channel 218 is located on the radial outer side of the aerosol product 7. The airflow in the air inlet channel 218 can be heated by the heat transferred by the heating component 2 in the extension direction of the atomizing channel 11 toward the aerosol outlet 411, thereby improving the heat utilization efficiency of the heating component 2.

[0047] Specifically, in one embodiment, please refer to... Figure 3 and Figure 4The heating assembly 2 includes a heating cylinder 21, which is open at one end and closed at the other end in the direction of the atomization channel 11. The closed end of the heating cylinder 21 forms the suspension end 217 of the heating assembly 2. The heating cylinder 21 has a side wall 211 and a bottom wall 213. The bottom wall 213 is located at the suspension end 217 of the heating assembly 2. An outward protrusion 215 is located at the open end of the heating cylinder 21. The internal cavity of the heating cylinder 21 forms a receiving cavity 216. The opening of the receiving cavity 216 is located at the open end of the heating cylinder 21. The bottom wall of the receiving cavity 216 is the heating cylinder 2. The bottom wall 213 of the heating cylinder 21; at least a portion of the heating cylinder 21 may be made of magnetic material, including materials such as SUS430 or SPCE (cold-rolled carbon steel for deep drawing) that can generate heat in an alternating magnetic field. For example, the side wall 211 of the heating cylinder 21 contains magnetic material, or the bottom wall 213 of the heating cylinder 21 contains magnetic material, or the entire heating cylinder 21 is made of magnetic material. In this way, after the coil 3 is energized, part or all of the heating cylinder 21 made of magnetic material can generate heat in an alternating magnetic field to heat the aerosol product 7.

[0048] The heating cylinder 21 has a contact protrusion 212 on its side wall 211 that protrudes radially toward the cavity 216. There are multiple contact protrusions 212, and two adjacent contact protrusions 212 are arranged at intervals to form an airflow groove. The contact protrusions 212 are used to contact the aerosol product 7 so that the groove wall of the airflow groove and the aerosol product 7 enclose each other to form an air inlet channel 218.

[0049] In one embodiment, contact protrusions 212 may be arranged in the extending direction of the atomizing channel 11, and adjacent contact protrusions 212 may be spaced apart in the circumferential direction of the heating cylinder 21. This forms multiple air intake channels 218 surrounding the aerosol product 7 between the heating cylinder 21 and the aerosol product 7, and the multiple air intake channels 218 are arranged in the extending direction of the atomizing channel 11. Of course, in other embodiments, the contact protrusions 212 may be dot-shaped protrusions, and the air intake channels 218 may be bent channels.

[0050] The air inlet channel 218 can communicate with the atomization channel 11 between the atomizing body 1 and the aerosol product 7. This allows the airflow from the aerosol outlet 411 on the device body 4, which enters the area between the atomizing body 1 and the aerosol product 7, to flow into the air inlet channel 218 along the atomization channel 11. Please refer to [reference needed]. Figure 3The hollow arrow in the figure indicates the airflow direction. The airflow in the air inlet channel 218 can contact the side wall 211 of the heating cylinder 21, so that the airflow is heated by the side wall 211 of the heating cylinder 21 to form a hot airflow. The hot airflow can enter the aerosol product 7 through the air inlet cavity 219 at the end of the aerosol product 7, thereby heating the aerosol product 7 and achieving uniform heating of the aerosol product 7. In addition, since the contact protrusion 212 is in contact with the aerosol product 7, the heat on the side wall 211 of the heating cylinder 21 can be transferred to the aerosol product 7 through the contact protrusion 212, thereby heating the aerosol product 7. In this way, the aerosol product 7 can be heated by both direct contact and hot airflow, which helps to ensure that the aerosol product 7 is fully heated and can improve the heating efficiency of the heating component 2.

[0051] For further information, please continue to refer to [link / reference]. Figure 3 and Figure 4 The air inlet chamber 219 can be located within the accommodating cavity 216, between the aerosol product 7 and the bottom wall 213 of the heating cylinder 21. A limiting protrusion 214 facing the aerosol product 7 is provided on the bottom wall 213 of the heating cylinder 21. The limiting protrusion 214 can extend radially along the heating cylinder 21 and can be arranged radially close to the side wall 211 of the heating cylinder 21, so that the limiting protrusion 214 connects with the contact protrusion 212, facilitating the processing of the limiting protrusion 214 and the contact protrusion 212. Alternatively, the limiting protrusion 214 can also be located radially at the center of the bottom wall 213 of the heating cylinder 21. The end face of the aerosol product 7 in the extension direction of the atomization channel 11 contacts the limiting protrusion 214, thereby enclosing the air inlet chamber 219 between the bottom wall 213 of the heating cylinder 21 and the aerosol product 7. Please continue to refer to... Figure 3 The hot airflow in the air intake channel 218 can be further heated by the heating cylinder 21 in the air intake chamber 219. The heated hot airflow can enter the aerosol product 7 from the end of the aerosol product 7 to achieve heating of the aerosol product 7.

[0052] In the above embodiments, both the air intake channel 218 and the air intake chamber 219 are located inside the heating cylinder 21. The intake airflow contacts the contact protrusion 212 and the limiting protrusion 214, which can increase the contact area between the intake airflow and the heating cylinder 21 and help improve the heat exchange efficiency between the heating cylinder 21 and the airflow.

[0053] In other embodiments, the heating cylinder 21 does not have a contact protrusion 212 and a limiting protrusion 214. The air inlet channel 218 and the air inlet chamber 219 can both be located outside the heating cylinder 21. For example, the air inlet channel 218 can be located between the side wall of the heat insulation cylinder 13 and the side wall 211 of the heating cylinder 21. The first connecting member 14 is provided with an air inlet hole for connecting the aerosol outlet 411 on the main body of the connecting device 4 and the air inlet channel 218. The airflow enters the air inlet channel 218 from the aerosol outlet 411 along the air inlet. The side wall 211 of the heating cylinder 21 can transfer heat to the airflow in the air inlet channel 218 to achieve heating of the airflow. The air inlet chamber 219 is located on the side of the accommodating cavity 216 away from the aerosol outlet 411 in the extension direction of the atomization channel 11. For example, it can be located between the bottom wall 213 of the heating cylinder 21 and the second connecting member 15, or between the bottom wall 213 of the heating cylinder 21 and the bottom wall of the heat insulation cylinder 13. A through hole is provided on the bottom wall 213 of the heating cylinder 21, which connects the air inlet chamber 219 and the accommodating cavity 216. In this way, the airflow in the air inlet channel 218 can pass through the air inlet chamber 219 and the through hole on the bottom wall 213 of the heating cylinder 21 in sequence and enter the accommodating cavity 216 to heat the aerosol product 7. When the airflow flows through the air inlet chamber 219, the bottom wall 213 of the heating cylinder 21 can reheat the airflow to increase the temperature of the airflow entering the accommodating cavity 216.

[0054] In the above embodiment, the coil 3 generates an alternating magnetic field after being energized, and the heating cylinder 21 can generate heat in the alternating magnetic field to heat the airflow and aerosol product 7. Since the coil 3 is located on the side of the bottom wall 213 of the heating cylinder 21 away from the side wall 211 in the extension direction of the atomization channel 11, the distance between the coil 3 and the bottom wall 213 of the heating cylinder 21 is smaller than the distance between the coil 3 and the side wall 211 of the heating cylinder 21. Thus, the heating temperature of the bottom wall 213 of the heating cylinder 21 is higher than that of the side wall 211. Therefore, the bottom wall 213 of the heating cylinder 21 is the main heating part, and the side wall 211 of the heating cylinder 21 is the auxiliary heating part. In this way, the heat on the heating cylinder 21 is mainly concentrated at the bottom of the heating cylinder 21, which can reduce the heat transfer in the extension direction of the atomization channel 11 towards the aerosol outlet 411, thereby improving the heat utilization rate of the heating component 2.

[0055] In another embodiment, the heating cylinder 21 may be made of thermally conductive ceramic material, and the heating assembly 2 includes a heating element fixed to the bottom wall 213 and / or the side wall 211 of the heating cylinder 21. The heating element is made of magnetic material and can generate heat in an alternating magnetic field. The heat generated by the heating element can be directly transferred to the airflow in the air intake channel 218 and the air intake chamber 219, or the heat generated by the heating element can be transferred to the airflow in the air intake channel 218 and the air intake chamber 219 through the heating cylinder 21 to heat the airflow. The heat generated by the heating element can also be transferred to the aerosol product 7 through the heating cylinder 21 to heat the aerosol product 7.

[0056] This application also discloses a heating non-combustible device; please refer to...
