Technical Field
[0001] This application relates to the field of atomization technology, and more specifically to an atomization heating device and atomization equipment. Background Technology
[0002] Atomizing devices typically include a heating device and a power supply unit. The heating device heats the aerosol-generating product to produce aerosol. Some existing heating devices heat the aerosol-generating product placed inside the heating cylinder by surrounding it with heating elements. However, because the heating cylinder is electrically connected to the power supply unit of the atomizing device through an external wire, there is a problem with poor sealing, which affects the content and quality of the aerosol inhaled by the user, resulting in a poor user experience. Utility Model Content
[0003] This application provides a heating device and atomizing equipment that can accelerate the generation of aerosols and fully realize the heating of aerosol-generated products, thereby improving the user experience.

[0007] A heating element, inserted into a heating cylinder, includes a fixing part and an insertion part. The fixing part and the heating cylinder enclose a heating cavity, which communicates with an air inlet. An aerosol generating product is inserted into the heating cavity through the air inlet. The insertion part extends into the heating cavity and is used to insert into the interior of the aerosol generating product.
[0008] An electromagnetic coil is disposed on the outside of the support member. When the electromagnetic coil is energized, it can generate an alternating magnetic field to induce heating in the heating cylinder or the heating element.
[0009] In some embodiments, the heating cylinder, the heating element, and the electromagnetic coil are all coaxially arranged with the support member; the position of the heating cylinder or the heating element corresponds to that of the electromagnetic coil in the axial direction of the support member.
[0010] In some embodiments, at least a portion of the structure of the heating cylinder is made of a soft magnetic material; the dimension of the heating cylinder in the axial direction of the support is less than or equal to the dimension of the electromagnetic coil in the axial direction of the support.
[0011] In some embodiments, at least a portion of the structure of the heating element is made of a soft magnetic material; the dimension of the heating element in the axial direction of the support is less than or equal to the dimension of the electromagnetic coil in the axial direction of the support.
[0012] In some embodiments, the electromagnetic coil includes a plurality of coil units arranged sequentially along the axial direction of the support member. Each coil unit is provided with a conductive part for individually connecting the coil unit to the power supply host.
[0013] In some embodiments, the heating element has an airflow channel that communicates with the external environment through the air inlet. The airflow channel includes a first airflow channel and a second airflow channel that are interconnected. The first airflow channel is formed on the inner wall of the heating element. A support structure is provided on the inner wall of the heating element or on the fixing part. The support structure abuts against the end of the aerosol generating article to form the second airflow channel between the end of the aerosol generating article and the fixing part.
[0014] In some embodiments, the inner wall of the heating cylinder is provided with a plurality of spaced protrusions, the protrusions being able to abut against the outer wall of the aerosol generating article, and the first airflow channel is formed between two adjacent protrusions.
[0015] In some embodiments, the atomizing heating device further includes a first clamping member and a second clamping member coaxially arranged with the support member. Both the first clamping member and the second clamping member are hollow structures with openings at both ends. The second clamping member communicates with the heating chamber through the first clamping member. The first clamping member is inserted into the support member along the air inlet, and the heating cylinder is clamped between the support member and the first clamping member. The second clamping member is located on the side of the first clamping member away from the heating cylinder.
[0016] The support member has a first suspension part, which protrudes radially from the inner wall of the support member. The heating cylinder has a second suspension part, which protrudes radially from the heating cylinder and is clamped between the first suspension part and the first clamping member.
[0017] In some embodiments, the support includes a support base and a support base. The support base is a hollow structure with openings at both ends.

[0019] The atomizing heating device according to the above embodiments includes a support, a heating cylinder, a heating element, and an electromagnetic coil. The electromagnetic coil is disposed on the outside of the support. When the electromagnetic coil is energized, it generates an alternating magnetic field, which can induce heating in the heating cylinder or the heating element. Since the electromagnetic coil is disposed on the outside of the support, and the heating cylinder and the heating element are disposed inside the support, no external wires are required inside the support, which can effectively ensure the sealing of the support. When the electromagnetic coil is energized and generates a magnetic field, the heating cylinder and the heating element can induce heating as a heat source. This heat source can not only heat the air to form a hot airflow, which can be used to heat the aerosol-generating product, but also can be transferred to the aerosol-generating product. By using surrounding heating and center heating to heat the aerosol-generating product, the area of the entire heating process can be increased, the aerosol generation speed can be accelerated, and the all-round heating method can make the aerosol-generating product evenly and fully heated, thereby improving the taste of the aerosol and improving the user experience.

[0032] This application provides an atomizing device that uses the principle of heating without combustion to heat aerosol product A, thereby generating an aerosol for user use.
[0033] It should be noted that the term "aerosol" in this context refers to a dispersion of solid or liquid particles in a gas. The term "aerosol" as used herein can generally refer to substances that have been vaporized, atomized, sprayed, or jetted, or otherwise transformed from a solid or liquid form into an inhalable form containing suspended solid or liquid drug particles.
[0034] As used herein, the term "aerosol-generating article A" refers to any suitable compound or mixture of compounds that facilitates the formation of aerosols (e.g., stable aerosols that are substantially resistant to thermal degradation at the operating temperature of the system) during use. Suitable aerosol-generating articles A are well known in the art and include, but are not limited to: polyols such as triethylene glycol, 1,3-butanediol, and glycerol; esters of polyols such as mono-, di-, or triacetic acid esters of glycerol; and aliphatic esters of mono-, di-, or polycarboxylic acids such as dimethyl dodecanoate and dimethyl tetradecanoate.
[0035] Aerosol-generating article A may include nicotine. Aerosol-generating article A may include water. Aerosol-generating article A may include glycerol (also known as glycerol) having a higher boiling point than nicotine. Aerosol-generating article A may include propylene glycol. Aerosol-generating article A may include plant-based materials. Aerosol-generating article A may include homogeneous plant substrate. The homogeneous plant substrate may contain volatile compounds. These compounds may be released from aerosol-generating article A upon heating. Aerosol-generating article A may be formed by winding and overmolding a soft paper material or a rigid material, and aerosol-generating article A has a generally cylindrical structure.
[0036] Please see Figure 1 The atomizing device includes a housing assembly 1, a power supply unit 2, and an atomizing heating device 3. The housing assembly 1 can be assembled from one or more components to house the power supply unit 2 and the atomizing heating device 3. The housing assembly 1 has an internal installation space 11 within which the power supply unit 2 and the atomizing heating device 3 are housed. The housing assembly 1 facilitates the transportation and carrying of the device. The power supply unit 2 and the atomizing heating device 3 are electrically connected. The power supply unit 2 includes a battery 21, a control circuit board 22, and control buttons (not shown in the figure). The power supply unit 2 provides the power required for the atomizing heating device 3 to operate and can also control the adjustment of the operating power (or operating temperature) of the heating device 3. The heating device 3 is used to electrically heat the aerosol to generate product A to form an aerosol.
[0037] Since the power supply host 2 and the housing assembly 1 have been disclosed in the prior art and are not the core points of the improvement in this application, the structure of the atomizing heating device 3 will be described in detail below.
[0038] Please see Figures 2 to 8The atomizing heating device 3 includes a support member 31, a heating cylinder 32, a heating element 33, and an electromagnetic coil 34. The support member 31 has an air inlet 311. The heating cylinder 32 is suspended inside the support member 31, and the heating element 33 is inserted into the heating cylinder 32. The heating element 33 includes a fixing part 331 and an insertion part 332. The fixing part 331 and the heating cylinder 32 enclose a heating cavity 35, which is connected to the air inlet 311. The aerosol generating product A is inserted into the heating cavity 35 through the air inlet 311. The insertion part 332 extends into the heating cavity 35 and is used to insert into the interior of the aerosol generating product A. The electromagnetic coil 34 is located on the outside of the support member 31. When the electromagnetic coil 34 is energized (or connected to an alternating current), it can generate an alternating magnetic field, which is used to induce heating in the heating cylinder 32 or the heating element 33.
[0039] The air inlet 311 can serve as an opening connecting the entire atomizing heating device 3 to the external environment, allowing outside air to enter the atomizing heating device 3. It can also serve as an opening for installing other components, such as mounting the heating element 32 inside the support member 31 through the air inlet 311. The fixing part 331 and the heating element 32 cooperate to form a heating chamber 35 that is open at one end and closed at the other. Please refer to [link / reference]. Figure 6 Of course, please refer to Figure 7 Alternatively, the heating cylinder 32 can be configured as a structure with one end closed and the other end open. The heating chamber 35 is formed inside the heating cylinder 32, and the insertion part 332 is set inside the heating cylinder 32 as a heating element 33. The opening of the heating chamber 35 is connected to the air inlet 311, which allows outside air to enter the heating chamber 35 and be heated to form a hot airflow. The insertion part 332 can be inserted into the interior of the aerosol generating product A, which can fix the aerosol generating product A and prevent it from shifting due to shaking during use, thus affecting the suction effect.
[0040] Since the electromagnetic coil 34 is located on the outside of the support member 31, and the heating cylinder 32 and the heating element 33 are both located inside the support member 31, when the electromagnetic coil 34 is energized to generate a magnetic field, the heating cylinder 32 and the heating element 33 can sense and generate heat as a heat source. This heat source can not only heat the air to form a hot airflow and use the hot airflow to heat the aerosol-generating product A, but also transfer heat to the aerosol-generating product A. By using surrounding heating and center heating to heat the aerosol-generating product A, the area of the entire heating process can be increased, the aerosol generation speed can be accelerated, and the all-round heating method can make the aerosol-generating product A evenly and fully heated, thereby improving the taste of the aerosol and improving the user experience.
[0041] Since the electromagnetic coil 34 is located outside the support member 31, no external wires are needed inside the support member 31, which can effectively ensure the sealing of the support member 31. Since the heating cylinder 32 and the heating element 33 are located inside the support member 31, and the fixing part 331 of the heating cylinder 32 and the heating element 33 encloses and forms a heating cavity 35 that communicates with the air inlet 311, the heating cavity 35 has no other openings that communicate with the external environment except for the air inlet 311, which can effectively ensure the sealing of the heating cavity 35 and effectively ensure that the aerosol in the heating cavity 35 can be drawn by the user based on negative pressure.
[0042] In some embodiments, the heating cylinder 32, the heating element 33, and the electromagnetic coil 34 are all coaxially arranged with the support member 31, which facilitates the assembly of the device. The heating cylinder 32 or the heating element 33 corresponds to the position of the electromagnetic coil 34 in the axial direction of the support member 31, which enables the heating cylinder 32 or the heating element 33 to be placed in the magnetic field, effectively ensuring that the heating cylinder 32 or the heating element 33, as the sensing structure, can generate heat.
[0043] In some specific embodiments, at least a portion of the structure of the heating element 32 is made of a soft magnetic material, including but not limited to stainless steel or carbon material. The heating element 32 is capable of inductively generating heat in an alternating magnetic field. The dimension of the heating element 32 along the axial direction of the support member 31 is less than or equal to the dimension of the electromagnetic coil 34 along the axial direction of the support member 31, allowing the heating element 32 to be completely contained within the magnetic field, thereby improving the heating efficiency of the entire heating device and reducing energy loss. Since the electromagnetic coil 34 is located on the outside of the support member 31, and the support member 31 is provided between the heating element 32 and the electromagnetic coil 34, the support member 31 is made of a material that does not generate heat in a magnetic field, and the support member 31 cannot shield the magnetic field, thus effectively ensuring that the heating element 32 is placed within the magnetic field.
[0044] In some specific embodiments, at least a portion of the structure of the heating element 33 is made of a soft magnetic material. The heating element 33 is capable of inducing heat in an alternating magnetic field. The dimension of the heating element 33 in the axial direction of the support 31 is less than or equal to the dimension of the electromagnetic coil 34 in the axial direction of the support 31, so that the heating element 33 can be completely contained in the magnetic field, thereby improving the heating efficiency of the entire heating device and reducing energy loss. Since the electromagnetic coil 34 is located on the outside of the support 31, the support 31 and the heating cylinder 32 are provided between the heating element 33 and the electromagnetic coil 34. The support 31 and the heating cylinder 32 are made of materials that do not generate heat in a magnetic field and do not shield the magnetic field. At the same time, since the heating cylinder 32 forms a heating cavity 35 and heats the aerosol-generated product A from the surroundings, the material of the heating cylinder 32 has high thermal conductivity, such as being made of ceramic materials such as silicon carbide, alumina, and aluminum nitride.
[0045] Since the fixing part 331 and the insertion part 332 constitute the heating element 33, at least one of the fixing part 331 and the insertion part 332 can be made of a soft magnetic material. That is, it can be understood that both the fixing part 331 and the insertion part 332 can be made of soft magnetic material, or at least a part of the fixing part 331 can be made of soft magnetic material, or at least a part of the insertion part 332 can be made of soft magnetic material.
[0046] In some specific embodiments, the electromagnetic coil 34 includes multiple coil units arranged sequentially along the axial direction of the support member 31. Each coil unit is provided with a conductive part for individual electrical connection between the coil unit and the power supply host 2. During suction, the user can select the number of coil units to be engaged according to the actual situation. At the same time, the user can also adjust the current flowing through the coil units at different positions to change the magnetic field strength, thereby changing the temperature of the corresponding heating cylinder 32 or insertion part 332. For example, the temperature gradient can be controlled and adjusted along the axial direction of the aerosol generating product A so that the temperature near the air inlet 311 is relatively low, which can prevent the user from being burned by excessively high aerosol temperature.
[0047] During the suction process, based on the principle of negative pressure, outside air enters the heating chamber 35 through the air inlet 311 and then enters the interior of the aerosol generating product A from the end of the aerosol generating product A. When passing through the heating chamber 35, it is heated to form a hot airflow. The hot airflow can not only heat the aerosol generating product A, but also carry the generated aerosol to the user's suction end. There is an airflow channel 321 in the heating chamber 35 to allow outside air and hot airflow to pass through.
[0048] In some specific embodiments, the heating cylinder 32 has an airflow channel 321, which communicates with the external environment through an air inlet 311. The airflow channel 321 includes a first airflow channel 3211 and a second airflow channel 3212 that are interconnected. The first airflow channel 3211 is formed on the inner wall of the heating cylinder 32. A support structure 36 is provided on the inner wall of the heating cylinder 32 or on the fixing part 331. The support structure 36 abuts against the end of the aerosol generating product A to form the second airflow channel 3212 between the end of the aerosol generating product A and the fixing part 331. The first airflow channel 3211 is formed between the inner wall of the heating cylinder 32 and the outer wall of the aerosol generating product A. The external dimensions or the dimensions of some structures of the aerosol generating product A can be slightly smaller than the inner diameter of the heating cylinder 32. The second airflow channel 3212 is formed between the end of the aerosol generating product A and the fixing part 331, so that the hot airflow in the heating chamber 35 flows along the first airflow channel 3211, changes direction through the second airflow channel 3212 and flows into the interior of the aerosol generating product A from the end. The first airflow channel 3211 provides a heat exchange path for the air heating and the hot airflow, and the second airflow channel 3212 provides a buffer space for the hot airflow, thereby ensuring that the aerosol generating product A is continuously heated by the hot airflow.
[0049] Please see Figure 4 In one specific embodiment, the inner wall of the heating cylinder 32 is provided with a plurality of spaced protrusions 322, which can abut against the outer wall of the aerosol generating product A, and a first airflow channel 3211 is formed between two adjacent protrusions 322. In order to reduce the flow resistance of hot air and the suction resistance of the customer, the protrusions 322 are strip-shaped protrusions extending along the axial direction of the heating cylinder 32, thereby forming a straight first airflow channel 3211 extending along the axial direction of the heating cylinder 32 between two adjacent protrusions 322. Of course, in other embodiments, the protrusions 322 can be provided as dot-shaped or block-shaped protrusions on the inner wall of the heating cylinder 32, and the plurality of protrusions 322 are uniformly arranged along the axial direction and radial direction of the heating cylinder 32, so that after the aerosol generating product A is inserted, the hot airflow around it is evenly distributed, ensuring that the aerosol generating product A is uniformly heated.
[0050] In some embodiments, the support structure 36 includes a support protrusion 361, which is disposed on the heating cylinder 32 near the fixing part 331, or on the end face of the fixing part 331 facing the air inlet 311. When the aerosol generating article A is installed, it can abut against the end of the aerosol generating article A to limit the insertion depth of the aerosol generating article A. It can also form a second airflow channel 3212 between the end of the aerosol generating article A, the fixing part 331 and the support protrusion 361.
[0051] In some specific embodiments, a support protrusion 361 is provided, and its size is smaller than the inner diameter of the heating cylinder 32 and the size of the fixing part 331. That is, if the support protrusion 361 does not completely cover the heating cylinder 32 or the fixing part 331 in the radial direction, the first airflow channel 3211 and the second airflow channel 3212 will automatically connect at the location where the support protrusion 361 is not provided. In other specific embodiments, please refer to... Figure 5 Multiple support protrusions 361 can be provided, and the multiple support protrusions 361 are spaced apart. An airflow gap 362 is formed between two support protrusions 361. The airflow gap 362 can connect the first airflow channel 3211 and the second airflow channel 3212. The multiple support protrusions 361 are evenly arranged along the circumference of the heating cylinder 32, so that the hot airflow can enter the second airflow channel 3212 evenly.
[0052] In some embodiments, the support protrusion 361 may be configured to include a strip-shaped protrusion extending along the axial direction of the heating cylinder 32. The arrangement of the strip-shaped protrusion causes the airflow gap 362 to extend along the axial direction of the heating cylinder 32, thereby further reducing the resistance to airflow and allowing air to smoothly enter the second airflow channel 3212.
[0053] In some embodiments, the airflow gap 362 formed between the support protrusions 361 and the first airflow channel 3211 are provided in a one-to-one correspondence and are connected to each other, so that the airflow gap 362 and the first airflow channel 3211 form a straight-through structure extending along the axial direction of the heating cylinder 32, which can further reduce the resistance to airflow.
[0054] In other specific embodiments, the support protrusions 361 may also be dot-shaped or block-shaped protrusions provided on the inner wall of the heating cylinder 32 or the fixing part 331. These dot-shaped or block-shaped protrusions may be cylindrical, conical, or rectangular. Multiple support protrusions 361 are evenly arranged along the circumference of the heating cylinder 32 or the fixing part 331, so that the airflow gaps 362 are evenly arranged, thereby allowing the hot airflow to evenly enter the second airflow channel 3212 along the airflow gaps 362 after the aerosol generating product A is inserted.
[0055] Please see Figure 3 , Figure 6 and Figure 7The atomizing heating device 3 also includes a first clamping member 37 and a second clamping member 38 coaxially arranged with the support member 31. Both the first clamping member 37 and the second clamping member 38 are hollow structures with openings at both ends. The first clamping member 37 is inserted into the support member 31 along the air inlet 311. The heating cylinder 32 is clamped between the support member 31 and the first clamping member 37. The second clamping member 38 is located on the side of the first clamping member 37 away from the heating cylinder 32. The second clamping member 38 communicates with the heating chamber 35 through the first clamping member 37, thereby allowing air to flow sequentially from the second clamping member. The openings of the second clamping member 38 and the first clamping member 37 enter the heating chamber 35. Multiple clamping protrusions 381 can be provided on the inner wall of the second clamping member 38. These protrusions are evenly and spaced along the circumference of the second clamping member 38. The clamping protrusions 381 can abut against the outer wall of the aerosol generating product A, and the gap between adjacent protrusions 381 provides a flow path for air. The arrangement of the clamping protrusions 381 also ensures that the aerosol generating product A is coaxially installed with the support member 31, thereby ensuring that the aerosol generating product A is heated uniformly. The heating cylinder 32 is clamped between the support member 31 and the first clamping member 37, facilitating the stable fixation of the heating cylinder 32.
[0056] Please see Figure 3 In some specific embodiments, the support member 31 is provided with a first suspension part 312, which protrudes radially from the support member 31 and is disposed on the inner wall of the support member 31. The heating cylinder 32 is provided with a second suspension part 323 on the outer wall of the heating cylinder 32, which protrudes radially from the heating cylinder 32 and is disposed on the heating cylinder 32. The second suspension part 323 is clamped between the first suspension part 312 and the first clamping member 37. The suspension of the heating cylinder 32 can reduce the contact area with other components, thereby reducing heat loss and improving the energy utilization rate of the atomizing heating device 3.
[0057] To facilitate the installation of the atomizing heating device 3, the support member 31 includes a support base 313 and a support base 314. The support base 313 is a hollow structure with openings at both ends. An air inlet 311 is formed at one end of the support base 313, and the support base 314 is sealed at the other end of the support base 313. The heating cylinder 32 is spaced apart from the support base 314, so that the heating cylinder 32 and the support member 31 only contact each other through the first suspension part 312 and the second suspension part 323. This reduces the contact area between the heating cylinder 32 and the support member 31, and further reduces the heat loss of the atomizing heating device 3.
[0058] To improve the sealing performance of the atomizing heating device 3, the support base 313 and the support base 314 are also provided with a sealing ring 315. The sealing ring 315 is made of silicone material, and the material production process is mature, which helps to reduce the production cost of the atomizing equipment.
[0059] To further reduce heat loss of the atomizing heating device 3, the support base 313 is made of heat-insulating material or a heat-insulating sleeve 316 is provided inside the support base 313.
[0060] Please see Figure 5 The insertion part 332 includes a piercing structure 3321 and an extension structure 3322. One end of the extension structure 3322 is disposed in the middle of the fixing part 331, and the other end is connected to the piercing structure 3321. The piercing structure 3321 is used to pierce the aerosol generating product A, so that at least part of the extension structure 3322 is inserted into the interior of the center of the aerosol generating product A, so as to ensure that the aerosol generating product A is coaxially installed with the heating chamber 35, so that the aerosol generating product A is uniformly heated.
[0061] In some specific embodiments, the insertion part 332 is constructed as a needle-like structure, a rod-like structure, or a sheet-like structure. One end of the needle-like structure, rod-like structure, and sheet-like structure is provided with a piercing structure 3321. The insertion part 332 can be a solid structure or an internally hollow structure, thereby reducing the weight and cost of the atomizing heating device 3.
[0062] In other specific embodiments, please refer to Figure 8 The insertion part 332 is constructed as a radial structure mainly composed of multiple sheet-like bodies 3323. One end of the multiple sheet-like bodies 3323 is connected, and the other end is arranged radially outward with the axis of the insertion part 332 as the center. Adjacent sheet-like bodies 3323 form the same included angle, so that the insertion part 332 and the aerosol generating product A are in uniform contact.
[0063] Since the inner wall of the heating cylinder 32 may come into contact with the aerosol-generating product A, the inner wall of the heating cylinder 32 is provided with an anti-stick coating (not shown in the figure) to reduce the adhesion of the aerosol-generating product A to the heating cylinder 32. The anti-stick coating is a dense coating structure formed by spraying nanomaterials or ceramic materials.
[0064] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
