Description

Technical Field

[0001] The present application relates to the field of heat-without-combustion technology, and more specifically to a heating device and a heat-without-combustion device. Background Art

[0002] The heating-without-burning device is a device that uses heating to atomize an aerosol-generating matrix to form an aerosol, and includes a heating device and a power supply component. The power supply component can provide the electricity required for the operation of the heating device, and the heating device provides heat for heating the atomized aerosol-generating matrix. In order to increase the efficiency of the heating device and make the aerosol-generating matrix heated evenly, some devices now use a central airflow heating method. The specific method is that when the user uses it, the outside air enters the heating channel through suction, and the heating device can heat the air to form a hot airflow, and the hot airflow flows into the aerosol-generating matrix for heating. The central airflow heating in the existing technology is an integral heating chamber. The space of the integral heating chamber is relatively large. When the airflow circulates, it is affected by natural convection, and the airflow is prone to backflow or counterflow, resulting in poor airflow heating effect, which affects the heating efficiency of the equipment.

[0026] The present application is further described in detail below by means of specific embodiments in conjunction with the accompanying drawings. Similar elements in different embodiments are numbered with associated similar elements. In the following embodiments, many detailed descriptions are provided to enable the present application to be better understood. However, those skilled in the art will readily appreciate that some of the features may be omitted in different circumstances, or may be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification. This is to avoid the core portion of the present application being overwhelmed by excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail. They can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0027] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various implementations, and the operational steps involved in each embodiment may be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for the purpose of clearly describing a particular embodiment and do not imply a required composition and / or sequence.

[0028] The serial numbers assigned to components herein, such as "first," "second," etc., are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0029] The present application provides a heating device 2 and a heat-without-combustion device using the heating device 2, which is capable of heating a solid aerosol-generating substrate A to generate an aerosol. In one embodiment, the heat-without-combustion device heats the aerosol-generating substrate A without burning the aerosol-generating substrate A. During heating, the aerosol-generating substrate A generates an aerosol without generating an open flame, thereby reducing the generation of harmful substances that would be produced by the high-temperature decomposition of the conventional aerosol-generating substrate A during combustion.

[0030] It should be noted that the term "aerosol" refers to a dispersion of solid or liquid particles in a gas. "Aerosol" is generally used to refer to a substance that has been vaporized, atomized, in the form of a spray or jet, or otherwise converted from a solid or liquid form into an inhalable form containing suspended solid or liquid drug particles.

[0031] As used herein, the term "aerosol-forming substrate A" refers to any suitable compound or mixture of compounds that facilitates the formation of an aerosol (e.g., a stable aerosol that is substantially resistant to thermal degradation at the operating temperature of the system) during use. Suitable aerosol-forming substrates 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 glycerol mono-, di-, or triacetate; and aliphatic esters of mono-, di-, or polycarboxylic acids such as dimethyl dodecanedioate and dimethyl tetradecanedioate.

[0032] Aerosol-generating matrix A may include nicotine. Aerosol-generating matrix A may include water. Aerosol-generating matrix A may include glycerol (also known as glycerol) having a higher boiling point than nicotine. Aerosol-generating matrix A may include propylene glycol. Aerosol-generating matrix A may include a plant-based material. Aerosol-generating matrix A may include a homogenized plant-based material. The homogenized plant-based material may contain volatile compounds. These compounds may be released from aerosol-generating matrix A upon heating. Aerosol-generating matrix A may be contained in a container to form a columnar structure having a predetermined length, etc.

[0033] See also Figures 1 to 7 The heating device 2 includes a support component 21 and a heating element 22. The support component 21 has a receiving cavity 211 inside, which is used to accommodate the aerosol generating substrate A. At least part of the structure of the heating element 22 is inserted into the receiving cavity 211 and inserted into the aerosol generating substrate A placed in the receiving cavity 211; the heating element 22 has a plurality of heating channels 221 that are not connected to each other, and the plurality of heating channels 221 are all extended along the axial direction of the heating element 22. Each heating channel 221 is correspondingly connected to at least one air inlet structure 222 and an air outlet structure 223. The air inlet structure 222 and the air outlet structure 223 are both connected to the heating channel 221. The heating element 22 is used to heat the airflow entering the heating channel 221 through the air inlet structure 222.

[0034] Specifically, the airflow enters from the air intake structure 222 corresponding to each heating channel 221, is heated by the heating element 22, and then flows to the aerosol generating substrate A through the air outlet structure 223. Since the heating element 22 is inserted in the aerosol generating substrate A, the aerosol generating substrate A can be heated by the central hot air flow, so that it is heated evenly. Since the heating channels 221 are not interconnected, the airflows in each heating channel 221 will not affect each other, and the airflows entering from multiple air intake structures 222 will not affect each other, avoiding backflow caused by the chaotic airflow. Different from the traditional integral heating chamber structure, the setting of multiple heating channels 221 reduces the volume of the space to be entered by the airflow, and can avoid the backflow phenomenon caused by the airflow entering a wider space from a narrow space, so that the airflow passes through the air intake structure 222, the heating channel 221 and the air outlet structure 223 in turn to flow to the aerosol generating substrate A, ensuring the heating effect and improving the heating efficiency of the heating device 2 and the heating without combustion equipment.

[0035] In some embodiments, each heating channel 221 is a straight-through structure extending along the axial direction of the heating element 22 , which not only simplifies the structure of the heating element 22 but also prevents airflow from running wild.

[0036] It should be further explained that the “plurality” mentioned in this application includes two or more. For example, there may be two heating channels 221 , or three, four or more heating channels.

[0037] See also Figure 3 and Figure 4 The heating body 22 includes a heating shell 224 and a barrier 225. The interior of the heating shell 224 has an installation cavity 2241. The barrier 225 is arranged in the installation cavity 2241 to separate the installation cavity 2241 to form a plurality of heating channels 221. At least part of the structure of the heating shell 224 is inserted into the aerosol generating substrate A. The air inlet structure 222 and the air outlet structure 223 are both arranged to pass through the side wall of the heating shell 224, so that the air flow can directly pass through the air outlet structure 223 and flow to the middle of the aerosol generating substrate A.

[0038] To facilitate the insertion of the heating housing 224 into the aerosol generating substrate A, in some embodiments, the heating housing 224 may be a needle-shaped structure. In some other embodiments, the heating housing 224 may include a base 2242 and an insertion portion 2243 connected to the base 2242. The insertion portion 2243 may be a conical or pyramidal structure. The base 2242 may be a hollow structure with at least one end open, that is, at least one end close to the air inlet structure 222 is open, so as to facilitate the installation of the barrier 225. The end of the base 2242 connected to the insertion portion 2243 may be closed or open. If it is open, the insertion portion 2243 is preferably a solid structure. Of course, when the interior of the insertion portion 2243 is a hollow structure, the overall shape of the barrier 225 should match the structure of the installation cavity 2241 of the heating housing 224 to ensure that the multiple heating channels 221 do not communicate with each other, thereby avoiding airflow disturbances.

[0039] See also Figure 4 In some embodiments, the barrier 225 is a sheet-like structure disposed within the mounting cavity 2241 to separate the mounting cavity 2241 into a first heating channel 2211 and a second heating channel 2212. The barrier 225 prevents the airflow entering from the air intake structure 223 corresponding to the first heating channel 2211 from interfering with the airflow entering from the air intake structure 223 corresponding to the second heating channel 2212. This embodiment has a simple structure and is easy to manufacture.

[0040] Of course, in some other embodiments, the barrier 225 includes at least two radially arranged sheet bodies 2251, one side of the sheet body 2251 is connected as a whole, and the other side extends to abut against the cavity wall of the installation cavity 2241, so as to evenly divide the installation cavity 2241 into a plurality of heating channels 221. For example, there are three sheet bodies 2251, one side of the three sheet bodies 2251 is connected as a whole, and the other side extends to abut against the cavity wall of the installation cavity 2241, so as to evenly divide the installation cavity 2241 into three heating channels 221. For another specific embodiment, please refer to Figure 5 There are four sheet-like bodies 2251 , one side of the three sheet-like bodies 2251 is connected as a whole to form a "cross" structure, and the other side extends to abut against the cavity wall of the installation cavity 2241 , dividing the installation cavity 2241 into four heating channels 221 .

[0041] In some specific embodiments, see Figure 4The air inlet structure 222 and the air outlet structure 223 are both arranged in a one-to-one correspondence with the heating channel 221. During suction, the airflow in the heating channel 221 comes from its corresponding air inlet structure 222 and flows out from its corresponding air outlet structure 223. The air inlet structures 222 corresponding to each heating channel 221 will not affect each other. Based on the heating characteristics of the central hot air flow, in order to make the airflow temperature in each heating channel 221 uniform, multiple air inlet structures 222 are arranged flush along the axial direction of the heating element 22, and multiple air outlet structures 223 are arranged flush along the axial direction of the heating element 22, so that the airflow heat exchange distance in each heating channel 221 is the same, so that the temperature of the airflow after heating is consistent.

[0042] To increase the airflow heating area and avoid uneven heating caused by concentrated hot air flow, each air outlet structure 223 includes multiple air outlet holes on the heating element 22. These multiple air outlet holes are evenly arranged along the sidewall of the heating housing 224. This allows the airflow within the same heating channel 221 to be dispersed and evenly flow toward the aerosol generating substrate A. To effectively ensure airflow, the air inlet structure 222 consists of a single airflow hole, the diameter of which is preferably 0.8 mm, and the air outlet hole is also preferably 0.8 mm.

[0043] Furthermore, in some embodiments, the multiple air outlet holes of the air outlet structure 223 can be set on the base 2242 of the heat-generating housing 224 , or on the inserting portion 2243 , or on both the base 2242 and the inserting portion 2243 .

[0044] See also Figure 2 In some embodiments, the heating element 22 further includes a heating coil 226, which is disposed outside the heating housing 224 and is used to generate a magnetic field to induce heating of the heating housing 224. The heating housing 224 is a structure made of ferromagnetic material, such as iron or steel (340 stainless steel). The heating coil 226 generates a magnetic field when energized. The heating housing 224, made of ferromagnetic material, is placed in this magnetic field and can generate heat, thereby heating the airflow inside it. In this embodiment, in order to reduce heat conduction and improve heating utilization, the barrier 225 is made of a material with low thermal conductivity, such as ceramic.

[0045] Of course, in some other embodiments, the barrier 225 can be a structure made of ferromagnetic material, so that after the heating coil 226 is energized to generate a magnetic field, the barrier 225 set in the magnetic field can generate heat to heat the airflow in the heating channel 221.

[0046] In some embodiments, a heating portion 227 is provided on the inner surface of the side wall of the heating housing 224 or the outer surface of the barrier 225. The heating portion 227 is used to generate heat when power is applied. The heating portion 227 is a conductive coating, a conductive film, a conductive sheet, or a conductive coil made of a conductive material. When power is applied, it directly generates heat, and the airflow passing through it can be heated. Accordingly, to protect the safety of the circuit, when the heating portion 227 is provided on the inner surface of the side wall of the heating housing 224, the barrier 225 is made of an insulating material, for example, a conductive insulating ceramic. When the heating portion 227 is provided on the barrier 225, the heating housing 224 is made of an insulating material.

[0047] In some embodiments, the heating device 2 also includes an air inlet channel 23, and the air inlet structure 222 is arranged on the support assembly 21. The air inlet structure 222 is connected to the outside world through the air inlet channel 23. When the user inhales, based on the Bernoulli negative pressure principle, the airflow can enter the interior of the heating device 2 along the air inlet channel 23, and then enter the heating channel 221 through the air inlet structure 222, and is heated to form a hot airflow, and then flows to the aerosol generating matrix A through the air outlet structure 223.

[0048] See also Figure 7 The support assembly 21 is used to fix the heating element 22. The support assembly 21 includes a first support member 212, a second support member 213 and a support base 214. The first support member 212 is sleeved on the outside of the second support member 213. The support base 214 is inserted at one end of the first support member 212. The receiving cavity 211 is formed inside the second support member 213. The air intake channel 23 is formed between the first support member 212, the second support member 213 and the support base 214. One end of the heating shell 224 is fixed on the support base 214, and the other end is inserted in the receiving cavity 211, and the air intake structure 222 is exposed, so that the air intake structure 222 is connected to the air intake channel 23. The air flow path is as follows Figure 7 As shown by the arrow in . In order to ensure safety, the support assembly 21 is made of high-temperature resistant PEEK material. The first support member 212 and the second support member 213 are both roughly cylindrical structures, which facilitates the heating coil 226 to be sleeved on the outer wall of the first support member 212, and the aerosol generating matrix A is accommodated inside the second support member 213. One end of the heating shell 224 is interference fitted on the support base 214, and the other end is interference fitted on the second support member 213. The support base 214 is interference fitted inside the first support member 212. A seal can also be provided between the support base 214 and the first support member 212 to ensure good sealing effect inside the support assembly 21 and avoid gas leakage.

[0049] For some heat-not-burn devices using heating device 2, please refer to Figure 8The heat-not-burn device includes a housing assembly 1, a heating device 2, and a power supply assembly 3. The heating device 2 and the power supply assembly 3 are both disposed within the housing assembly 1. The power supply assembly 3 includes a battery, a control circuit board, and operating buttons. The power supply assembly 3 is electrically connected to the heating device 2 to provide the power required for the heating device 2 to operate and control its operation. The housing assembly 1 can be understood as a collection of related structures that constitute the overall outer contour of the generating device. For example, the housing assembly 1 can be constructed from one or more components, and corresponding assembly structures are provided within or on the shell wall of the housing assembly 1 to facilitate assembly of other components of the generating device to the housing assembly 1. For example, the control circuit board and battery in the power supply assembly 3 can be assembled within the housing assembly 1, while the operating buttons in the power supply assembly 3 can be mounted on the housing assembly 1 in a manner that is exposed from the housing assembly 1. The support assembly 21 is also disposed within the housing assembly 1. Of course, in some other embodiments, the support assembly 21 and the housing assembly 1 are integrally structured, with structures such as the receiving cavity 211 and the air inlet channel 23 directly formed on the housing assembly 1.

[0050] The above specific examples are used to illustrate the present application, which is only used to help understand the present application and is not intended to limit the present application. For those skilled in the art of the present application, based on the concept of the present application, they can also make some simple deductions, modifications or substitutions.
