It is not necessary to describe the related operations in detail in the specification, and those skilled in the art can fully understand the related operations according to the description in the specification and the general technical knowledge in the art.

[0030] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various embodiments, and the operation steps involved in each embodiment can be sequentially adjusted or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only intended to clearly describe one embodiment, and do not mean that the composition and / or order is necessary.

[0031] The serial numbers of the components in this paper, such as "first", "second", etc., are only used to distinguish the described objects, and have no any order or technical meaning. Unless otherwise specified, "connection" and "coupling" in this application include direct and indirect connection (coupling).

[0032] The application provides a heating non-combustion device, which heats the aerosol generating article A by using the principle of heating non-combustion, so as to generate aerosol for the user to use.

[0033] It is noted that the term aerosol as used herein refers to a dispersion of solid or liquid particles in a gas. As used herein, "aerosol" can be used to refer generally 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 to an inhalable form comprising 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 an aerosol (e.g., a stable aerosol that is substantially resistant to thermal degradation at the operating temperature of the system) in use. Suitable aerosol generating articles A are well known in the art and include, but are not limited to: polyhydric alcohols such as triethylene glycol, 1,3-butanediol, and glycerol; esters of polyhydric alcohols such as glycerol mono-, di-, or triacetate; and aliphatic esters of mono-, di-, or poly-carboxylic acids such as dimethyl dodecanedioate and dimethyl tetradecanedioate.

[0035] The aerosol generating article A can include nicotine. The aerosol generating article A can include water. The aerosol generating article A can include glycerol (also known as glycerin), which has a higher boiling point than nicotine. The aerosol generating article A can include propylene glycol. The aerosol generating article A can include plant-based material. The aerosol generating article A can include homogenized plant substrate material. The homogenized plant substrate material can contain volatile compounds. These compounds can be released from the aerosol generating article A upon heating. The aerosol generating article A can be wrapped in a soft paper material or a hard material, and the appearance of the aerosol generating article A is generally cylindrical.

[0036] Referring to Figures 1 to 2 The heating non-combustion device includes a shell assembly 1, a power supply assembly 2, and a heating device 3. The shell assembly 1 can be assembled from one or more fittings, and is used to accommodate the power supply assembly 2 and the heating device 3. The shell assembly 1 is internally provided with a mounting space 11, and the power supply assembly 2 and the heating device 3 are arranged in the mounting space 11. The arrangement of the shell assembly 1 facilitates the transportation and carrying of the heating non-combustion device. The power supply assembly 2 and the heating device 3 are electrically connected, and include a battery 21, a control circuit board 22, and a control button (not shown in the figure), etc. The arrangement of the power supply assembly 2 provides the power required for the operation of the heating device 3, and can also control the adjustment of the working power (working temperature) of the heating device 3. The heating device 3 is used to heat the aerosol generating article A to form an aerosol.

[0037] Referring to Figures 1 to 8The heating device 3 comprises a support assembly 31 and a heating assembly 32. The support assembly 31 has a receiving cavity 311 for accommodating the aerosol generating article A. The receiving cavity 311 has a receiving opening 3111 for inserting the aerosol generating article A into the receiving cavity 311. The heating assembly 32 is arranged on the support assembly 31 and away from the receiving opening 3111. The heating assembly 32 comprises a heat conducting body 321 and a heating body 322. The heating body 322 is arranged on the side of the heat conducting body 321 away from the receiving opening 3111. The heating body 322 is used for heating by electricity and is in thermal contact with the heat conducting body 321. At least part of the heat conducting body 321 is used for inserting into the aerosol generating article A accommodated in the receiving cavity 311 and heating the aerosol generating article A to form an aerosol.

[0038] Since at least part of the structure of the heat conducting body 321 can be inserted into the aerosol generating article A and heat it, the aerosol generating article A can be heated centrally, so that the aerosol generating article A is heated uniformly and sufficiently. Since the heating body 322 is arranged on the side of the heat conducting body 321 away from the receiving opening 3111, i.e. on the side away from the aerosol generating article A, the heating source is not in direct contact with the aerosol generating article A, avoiding the phenomenon of burnt paste caused by direct contact between the heating source and the aerosol generating article A, avoiding the generation of impurities, thereby improving the taste of the aerosol and the user's experience. Since the heating assembly 32 comprises the heat conducting body 321 and the heating body 322, and the heating body 322 is arranged on the side of the heat conducting body 321, the structure of the heating assembly 32 is simple and convenient to process.

[0039] In some embodiments, at least part of the end of the heating assembly 32 away from the receiving opening 3111 is arranged spaced apart from the support assembly 31, so that at least part of the structure of the heating assembly 32 is suspended (hanging arrangement) on the side of the support assembly 31 away from the receiving opening 3111. For example, the support assembly 31 has a support structure in the inside, and the heating assembly 32 is arranged on the support structure, so that the heating assembly 32 is suspended in the support assembly 31. The heating assembly 32 is suspended in the support assembly 31, which can reduce the contact area between the heating assembly 32 and other components (such as the support assembly 31) in the heating device 3, reduce the heat loss of the heating assembly 32 based on contact conduction, and also reduce the temperature of other components, avoiding the failure of their functions caused by high temperature, thereby improving the service life of the heating device 3 and the heating non-combustion equipment.

[0040] In some specific embodiments, in order to improve the service life of the support assembly 31, the support assembly 31 can be made of PEEK material which is resistant to high temperature.

[0041] Please refer to Figure 3 andFigure 4 In some embodiments, the support assembly 31 comprises a support base 312 and a support seat 313, the accommodation opening 3111 is formed on the support base 312, the support seat 313 is arranged on the side of the support base 312 away from the accommodation opening 3111, and at least part of the structure of the support seat 313 is inserted into the inside of the support base 312. The mounting cavity 3131 is arranged on the support seat 313, at least part of the heat-conducting body 321 abuts against the inner wall of the mounting cavity 3131, and the remaining part is suspended in the mounting cavity 3131. The support assembly 31 is arranged as a support base 312 and a support seat 313 which are independent of each other, facilitating the processing and maintenance of the support assembly 31. The support seat 313 is inserted into the inside of the support base 312, and part of the structure of the heat-conducting body 321 is suspended in the mounting cavity 3131 of the support seat 313, facilitating the assembly and fixation of the heating assembly 32. The support seat 313 is used as a fixing structure of the heating assembly 32, which can further reduce the contact area between the heating assembly 32 and the support assembly 31. Since the heating body 322 is arranged on the side of the heat-conducting body 321 away from the accommodation opening 3111, the heat-conducting body 321 can at least partially enclose the mounting cavity 3131, and the heating body 322 and the aerosol generating article A are isolated, reducing the contact between the heating source and the aerosol generating article A.

[0042] In order to effectively ensure the air tightness of the inner wall of the heating device 3, the support assembly 31 further comprises a sealing member 316 arranged between the support base 312 and the support seat 313. The sealing member 316 is a sealing ring made of silica gel, which is sleeved on the outside of the support seat 313 to seal the assembly gap between the support seat 313 and the support base 312.

[0043] Please refer to Figure 6 In some specific embodiments, the mounting cavity 3131 is provided with a stepped structure 3132 on the side close to the accommodation opening 3111, and the heat-conducting body 321 abuts against the stepped structure 3132, so that the heat-conducting body 321 is suspended in the mounting cavity 3131. The stepped structure 3132 can be formed by two cavities which are continuously arranged and have different diameters, or can be formed by a plurality of protrusions arranged on the inner wall of the mounting cavity 3131. The protrusions can be cylindrical or conical, or the stepped structure 3132 is formed by an annular protrusion. Of course, in order to better support the heat-conducting body 321, the side surface of the protrusion and the annular protrusion facing the accommodation opening 3111 is a flat plane.

[0044] Please refer to Figures 3 to 6In some embodiments, the heat-conducting body 321 comprises an insertion portion 3211 and a fixing portion 3212, the fixing portion 3212 is suspended on the stepped structure 3132, and the insertion portion 3211 and the heat-generating body 322 are arranged on the two opposite sides of the fixing portion 3212. The insertion portion 3211 and the fixing portion 3212 can be a two-part structure independent of each other, or an integrally formed structure, and the insertion portion 3211 can be inserted into the inside of the aerosol generating article A. In some specific embodiments, the fixing portion 3212 is a disc structure with a certain thickness, has two opposite sides, and the insertion portion 3211 and the heat-generating body 322 are arranged opposite to each other. The heat generated by the heat-generating body 322 is transmitted to the aerosol generating article A through the fixing portion 3212 and the insertion portion 3211 in turn, which prolongs the distance of heat transmission, so as to control and reduce the heating temperature inside the aerosol generating article A, and avoid the phenomenon of burning due to too high temperature.

[0045] Please refer to Figure 4 In some embodiments, the end of the insertion portion 3211 away from the fixing portion 3212 is a conical structure, and the tip of the conical structure can be conveniently inserted into the inner wall of the aerosol generating article A. In some other embodiments, the insertion portion 3211 can be a sheet structure, and the sheet structure has a triangular cross-sectioned tip. Please refer to Figure 7 In some other embodiments, the insertion portion 3211 comprises a plurality of insertion sheets 3213, one end of the plurality of insertion sheets 3213 is connected, and the other end is arranged in a radial manner. The structure of the insertion sheet 3213 is the same as the above-mentioned sheet structure, and has a triangular cross-sectioned tip, which can also be conveniently inserted into the inner wall of the aerosol generating article A.

[0046] Since the insertion portion 3211 is inserted into the inside of the aerosol generating article A, the fixing portion 3212 and the end of the aerosol generating article A can be in contact. When the end of the aerosol generating article A is in contact with the fixing portion 3212, the flexible paper may be burned to produce smog. Therefore, the end of the aerosol generating article A should be spaced apart from the fixing portion 3212, and the spacing also provides a flow space 315 for the airflow. The flow space 315 is in communication with the accommodation opening 3111, so that when the user inhales, the airflow can flow from the flow space 315, through the end of the aerosol generating article A, and into the inside of the aerosol generating article A based on the principle of negative pressure.

[0047] In order to effectively ensure the spacing of the end of the aerosol generating article A and the fixing portion 3212, the support assembly 31 further comprises a limiting piece 314. The limiting piece 314 can limit the insertion depth of the aerosol generating article A. The limiting piece 314 is spaced apart from the fixing portion 3212, which can ensure the spacing of the aerosol generating article A and the fixing portion 3212. The limiting piece 314 can also ensure the consistency of the position of the aerosol generating article A each time it is installed, eliminate the differences in installation by different users, and effectively ensure the use effect of the aerosol generating article A. The limiting piece 314 is provided with an insertion hole 3143 and an airflow hole 3144. The heat conductor 321 passes through the insertion hole 3143. The airflow hole 3144 is in airflow communication with the airflow space 315.

[0048] Please refer to Figure 3 In some embodiments, the limiting piece 314 is connected with the support base body 312. One side of the limiting piece 314 is used to abut against the end of the aerosol generating article A, and the other side is spaced apart from the side of the fixing portion 3212 close to the accommodation opening 3111 to form an airflow space 315 between the limiting piece 314 and the fixing portion 3212. In order to adapt to the shape of the support base body 312 and the aerosol generating article A, the limiting piece 314 has a cup-shaped structure comprising a side wall 3141 and a bottom wall 3142. The side wall 3141 is provided with a flange connected with the inner wall of the support base body 312, and there is a gap between the side wall 3141 and the accommodation opening 3111. The bottom wall 3142 is provided on the side away from the accommodation opening 3111 and is spaced apart from the fixing portion 3212. The end of the aerosol generating article A abuts against the bottom wall 3142, and the airflow space 315 is formed between the bottom wall 3142 and the fixing portion 3212. After the air enters the inside of the heating device 3 from the accommodation opening 3111, it can flow into the outside of the limiting piece 314 along the gap and flow into the airflow space 315. The bottom wall 3142 is provided with an insertion hole 3143 and an airflow hole 3144. The insertion hole 3143 is used to install the fixed insertion portion 3211. The airflow hole 3144 can be uniformly provided with a plurality of airflow holes along the circumference of the insertion hole 3143. The airflow hole 3144 is in airflow communication with the airflow space 315. After the airflow passes through the airflow space 315 and the airflow hole 3144, it flows through the end of the aerosol generating article A and flows into the inside of the aerosol generating article A. At the same time, the airflow in the airflow space 315 contacts the fixing portion 3212 to form a hot airflow, which can heat the aerosol generating article A in a central hot airflow mode.

[0049] Please refer to Figure 5In some embodiments, the limiting member 314 is connected with the support base 313, one side of the limiting member 314 is used to abut against the end of the aerosol generating article A, and the other side is spaced apart from the side of the fixing portion 3212 close to the accommodation opening 3111 to form an airflow space 315 between the limiting member 314 and the fixing portion 3212, the airflow space 315 being in airflow communication with the accommodation opening 3111. The limiting member 314 includes a side wall 3141 connected with the support base 313 and a top wall 3145 disposed on the side of the side wall 3141 close to the accommodation opening 3111, the top wall 3145 abutting against the end of the aerosol generating article A, the top wall 3145 being provided with an insertion hole 3143 and airflow holes 3144, the insertion portion 3211 being fixed on the insertion hole 3143, the airflow holes 3144 being provided in multiple and uniformly arranged along the circumference of the insertion hole 3143, so that the airflow flowing into the inside of the aerosol generating article A is uniform, the airflow space 315 being formed between the top wall 3145 and the fixing portion 3212, the side wall 3141 being provided with air inlets 3146 in communication with the accommodation opening 3111, the air inlets 3146 being provided in at least two and uniformly arranged along the circumference of the side wall 3141, so that the airflow around the airflow space 315 uniformly enters. In this embodiment, the limiting member 314 and the support base 313 can be an integrally formed structure or two independent parts. Since the limiting member 314 is connected with the support base 313, the support base 313 is provided with a heat conductor 321, the limiting member 314 is preferably made of a material with poor thermal conductivity, so as to avoid the contact and heat conduction between the limiting member 314 and the support base 313, and to avoid the temperature of the limiting member 314 being too high to scorch the end of the aerosol generating article A when the end of the aerosol generating article A is contacted, thereby generating odor.

[0050] Of course, in other embodiments, the limiting member 314 can also include a side wall 3141 and limiting protrusions provided on the inner wall of the cavity enclosed by the side wall 3141, the limiting protrusions can abut against the end of the aerosol generating article A to limit the insertion depth, and form an airflow space 315 between the end of the aerosol generating article A and the fixed portion 3212, the limiting protrusions are provided in plurality and are spaced apart, and the gap between adjacent two limiting protrusions can allow airflow to pass through. When the partial structure of the aerosol generating article A is inserted into the cavity enclosed by the side wall 3141, the inner diameter of the side wall 3141 is slightly larger than the outer diameter of the aerosol generating article A, so that a gap for airflow to pass through is formed between the two. When the user inhales, the airflow flowing through the gap (including the gap between the side wall 3141 and the aerosol generating article A and / or the gap between adjacent two limiting protrusions) directly flows through the end of the aerosol generating article A via the airflow space 315 and flows into the inside of the aerosol generating article A. In this embodiment, the limiting member 314 can be an integral structure with the support base 313, that is, the length of the support base 313 is extended, and a plurality of limiting protrusions are provided on the inner wall of the side near the accommodation opening 3111. Of course, the limiting member 314 and the support base 313 can also be two independent parts.

[0051] Please refer to Figure 8 In some embodiments, the heating element 322 includes a heating circuit 3221 formed by printing the heating circuit 3221 on the side of the fixed portion 3212, which is printed and sintered from conductive metal paste. This manufacturing process is mature and convenient to process. The two ends of the heating circuit 3221 are provided with electrodes 3222, and the two electrodes 3222 are electrically connected to the power supply assembly 2 through wires, which can pass through the wire entry hole provided on the support base 313 to make the wires neat. Of course, in other embodiments, the heating element 322 can also include a heating coating or a heating film, or can be formed by fixing a heating wire on the fixed portion 3212 using a gluing or sintering process.

[0052] In order to better fix the aerosol generating article A and install it concentrically (coaxially with the accommodation cavity 311) to avoid uneven heating caused by eccentricity, the support assembly 31 includes a clamping member 33, and the inner wall of the clamping member 33 is provided with a plurality of clamping portions 331 for abutting against the outer wall of the aerosol generating article A to fix the aerosol generating article A and install it concentrically. The plurality of clamping portions 331 are spaced apart and uniformly arranged along the inner wall circumference of the clamping member 33 to form airflow passages 332 between adjacent two clamping portions 331, the airflow passages 332 are in communication with the accommodation opening 3111 and can be in communication with the airflow space 315, so that the airflow flows into the inside of the aerosol generating article A in sequence through the accommodation opening 3111, the airflow passages 332, and the airflow space 315 (the gas flow direction is as shown by the arrow in the figure). Figure 3 andFigure 5 The clamping portions 331 are uniformly arranged, so that the air flow passages 332 are uniform, and the air inlet of the aerosol generating article A is uniform, effectively ensuring uniform heating of the aerosol generating article A.

[0053] In some embodiments, the heat conductor 321 is configured to be made of a material with good heat conduction performance, including but not limited to aluminum nitride or hard anodized aluminum alloy. The material is easy to obtain and convenient to manufacture and process. When the heat conductor 321 is made of hard anodized aluminum alloy, since it has electrical conductivity, when the heat conductor 321 is in direct contact with the heating body 322, there is a possibility of short circuit between the heat conductor 321 and the heating body 322, thereby affecting the operation of the heating assembly 32. The heat conductor 321 and the heating body 322 are insulated, which can be achieved by brushing an insulating layer or wrapping the heating body 322 with insulating material.
