Referring to fig. 1 and 6, an aerosol-generating assembly 100 and an aerosol-generating device 1000 according to an embodiment of the present utility model are provided. The aerosol-generating assembly 100 comprises a heat-generating body 20, the heat-generating body 20 being for heating an aerosol-generating substrate 200 to produce an aerosol for use by a user. The heating mode can be convection, conduction, radiation or a combination thereof. The aerosol-generating substrate 200 may be a solid aerosol-generating substrate 200. The aerosol-generating substrate includes, but is not limited to, materials for medical, health, wellness, and cosmetic purposes, e.g., the aerosol-generating substrate 200 is a medicinal fluid, an oil, or the aerosol-generating substrate is a plant-based material, e.g., a plant root, stem, leaf, flower, bud, seed, etc.

Referring to fig. 1, fig. 1 shows an aerosol-generating assembly 100 according to an embodiment of the present utility model, the aerosol-generating assembly 100 includes a housing portion 10, a heating element 20, and a mouthpiece portion 30. The housing 10 is provided with a heating chamber 11, the heating chamber 11 being adapted to house an aerosol-generating substrate 200. The heating body 20 is disposed in the heating chamber 11, and the heating body 20 surrounds the central axis 12 of the accommodating portion 10 and is spaced from the side wall 112 of the heating chamber 11, so as to generate heat to heat the aerosol-generating substrate 200 to generate aerosol. The nozzle portion 30 is connected to the housing portion 10 and communicates with the heating chamber 11, and aerosol generated in the heating chamber 11 can enter the nozzle portion 30.

Referring to fig. 1 and 2, fig. 2 shows a cross section of a receiving portion of an aerosol-generating assembly 100 in an embodiment of the utility model. The heating body 20 is disposed around the central axis 12 of the housing part 10 and spaced apart from the side wall 112 of the heating chamber 11 such that the heating body 20 is spaced apart from both the central position and the edge position of the heating chamber 11, and heat can be uniformly transferred to the central position and the edge position of the heating chamber 11 in the case that the heating body 20 heats, so as to uniformly bake the aerosol-generating substrate 200 at each position within the heating chamber 11.

The heating element 20 of the conventional aerosol-generating device is often heated at the central position of the aerosol-generating substrate 200, for example, the heating element 20 is disposed at a position where the central axis 12 of the heating element 20 coincides with the central axis 12 of the accommodating portion 10, so that the heating element 20 is heated at the central position of the heating chamber 11, and the heating manner is such that the heat at the central position of the heating chamber 11 is concentrated, so that the aerosol-generating substrate 200 near the central position of the heating chamber 11 is easily burned, and the aerosol-generating substrate 200 near the central position of the heating chamber 11 is often not sufficiently burned while the aerosol-generating substrate 200 near the central position of the heating chamber 11 is burned, resulting in poor quality of the generated aerosol.

The heating body 20 of the aerosol-generating assembly 100 according to the embodiment of the present disclosure surrounds the central axis 12 of the accommodating portion 10, so that heat can be prevented from being concentrated at the central position of the heating chamber 11. The heating element 20 is spaced from the side wall 112 of the heating chamber 11 while surrounding the central axis 12 of the housing 10, so that the distance from the heating element 20 to the central position of the heating chamber 11 is uniform with the distance from the heating element 20 to the edge position of the heating chamber 11. That is, the heat generating body 20 is located near both the center of the heating chamber 11 and the edge of the heating chamber 11, so that the heat distribution in the diameter direction of the cross section of the heating chamber 11 is more uniform, and the situation that the aerosol-generating substrate 200 at a part of the positions is baked while the aerosol-generating substrate 200 at a part of the positions is still not yet baked sufficiently is avoided. In this way, the heating element 20 can bake the aerosol-generating substrate 200 more uniformly, and the quality of the generated aerosol can be improved.

Further description is provided below with reference to the accompanying drawings.

Referring to fig. 1 and 2, in some embodiments, the accommodating portion 10 is cylindrical, and the cross section of the accommodating portion 10 is circular. Referring to fig. 3, in some embodiments, the unfolded state of the accommodating portion 10 is rectangular, and the rectangular accommodating portion 10 is rolled into a tube shape during the production process, such that the heating cavity 11 is formed in the middle of the accommodating portion 10.

In some embodiments, during production of the aerosol-generating assembly 100, the receptacle 10, the heat-generating body 20, and the aerosol-generating substrate 200 are rolled together to form the receptacle 10 with the heat-generating body 20 and the aerosol-generating substrate 200 disposed within the heating chamber 11. As shown in fig. 2, both the side of the heat generating body 20 near the center of the heating chamber 11 and the side of the heat generating body 20 near the edge of the heating chamber 11 are filled with the aerosol-generating substrate 200, so that the heat generating body 20 is fixed in the aerosol-generating substrate 200.

In some embodiments, the housing portion 10 and the aerosol-generating substrate 200 that do not include the heat-generating body 20 may be rolled into a tube before the heat-generating body 20 is inserted into the aerosol-generating substrate 200 of the housing portion 10. Referring to fig. 3, in some embodiments, the distal end of the heat generating component 21 is tapered to facilitate insertion of the heat generating component 21 into the aerosol-generating substrate 200.

Referring to fig. 2 and 3, in some embodiments, the heat generating body 20 includes a plurality of heat generating components 21, and each of the heat generating components 21 is uniformly distributed with respect to the central axis 12 of the housing 10 at intervals. The number of the heat generating components 21 may be 2, 3, 4, 5 or more, which is not exemplified herein. The longitudinal direction of the heat generating member 21 coincides with the longitudinal direction of the housing portion 10 so that the aerosol-generating substrate 200 along the longitudinal direction of the housing portion 10 is uniformly heated. Each of the heat generating components 21 is spaced apart from each other so as to facilitate ventilation and to allow sufficient circulation of the aerosol generated in the heating chamber 11 during ventilation. In addition, the plurality of heat generating members 21 are spaced apart from each other, so that the concentration of heat around the heat generating member can be reduced, and the heat generating member can uniformly heat the aerosol-generating substrate 200 at each position.

Referring to fig. 4 and 5, fig. 4 shows a cross-section of a receiving portion of an aerosol-generating assembly 100 according to an embodiment of the utility model, and fig. 5 shows a deployed state of the receiving portion 10, the heating element 20 and the aerosol-generating substrate 200 of fig. 4. In some embodiments, the heat generating element 20 is rectangular in an expanded state, and the heat generating element 20 can be wound in a tubular shape in the tubular housing portion 10. The rectangular heating element 20 in the developed state is easily rolled into a cylindrical shape together with the housing 10 in the developed state, facilitating the automated production of the aerosol-generating assembly 100.

In some embodiments, the heating element 20 is provided with a plurality of hollow grooves 22, and the plurality of hollow grooves 22 are uniformly distributed on the heating element 20 at intervals. The hollow-out channel 22 can facilitate ventilation and adequate circulation of aerosol. The plurality of evenly distributed hollowed-out grooves 22 also can alleviate heat concentration around the heat generating element, which is beneficial for the heat generating element to evenly heat the aerosol-generating substrate 200 at each location.

Referring to fig. 2 and 4, in some embodiments, the thickness of the heater 20 may be in the range of 0.05mm,0.20mm to facilitate the loading of the heater 20 into the aerosol-generating substrate 200 while ensuring heating efficiency and baking efficiency, and to facilitate miniaturization of the aerosol-generating assembly 100. For example, the thickness of the heating element 20 may be 0.05mm, 0.07mm, 0.09mm, 0.11mm, 0.13mm, 0.15mm, 0.17mm, 0.19mm, 0.20mm, etc., which are not specifically mentioned herein.

Referring to fig. 2 and 4, in some embodiments, the distance from the heating element 20 to the sidewall 112 of the heating chamber 11 is equal to the distance from the heating element 20 to the central axis 12 of the accommodating portion 10. For example, in the embodiment illustrated in fig. 2, the distance D1 from the heat generating body 20 to the side wall 112 of the heating chamber 11 is equal to the distance D2 from the heat generating body 20 to the central axis 12 of the housing portion 10, and is one half radius. In this way, when the heating element 20 generates heat, the heating degree of the aerosol-generating substrate 200 near the outer peripheral edge of the heating chamber 11 and the heating degree of the aerosol-generating substrate 200 near the center of the heating chamber 11 are made close to each other, the heat distribution in the diameter direction of the cross section of the heating chamber 11 is made more uniform, and the quality of the generated aerosol is improved.

Referring to fig. 2 and 4, in some embodiments, the ratio of the distance from the heating element 20 to the sidewall 112 of the heating chamber 11 to the distance from the heating element 20 to the central axis 12 of the accommodating portion 10 is in the range of [0.9,1.1]. For example, in the embodiment illustrated in fig. 2, if the ratio of the distance D1 of the heat generating body 20 to the side wall 112 of the heating chamber 11 to the distance D2 of the heat generating body 20 to the central axis 12 of the housing portion 10 is smaller than 1, the heat generating body 20 is closer to the side wall 112 of the heating chamber 11; if the ratio of the distance D1 from the heat generating element 20 to the side wall 112 of the heating chamber 11 to the distance D2 from the heat generating element 20 to the central axis 12 of the housing portion 10 is greater than 1, the heat generating element 20 is closer to the central axis 12 of the housing portion 10. In the case where the ratio of the distance D1 to the distance D2 is in the range of [0.9,1.1], even if the heat generating body 20 is closer to the side wall 112 of the heating chamber 11 or to the central axis 12 of the housing portion 10, the degree of heating of the aerosol-generating substrate 200 at a position close to the outer periphery of the heating chamber 11 and the aerosol-generating substrate 200 at a position close to the center of the heating chamber 11 are relatively close, the heat distribution in the diameter direction of the cross section of the heating chamber 11 is relatively uniform, and it can be avoided that a part of the aerosol-generating substrate 200 is burned due to heat concentration and another part of the aerosol-generating substrate 200 is sufficiently heated.

Referring to fig. 1, 3 and 5, in some embodiments, the accommodating portion 10 includes a first end 15 and a second end 17 opposite to each other, and the first end 15 is connected to the suction nozzle portion 30. The distance from the heating element 20 to the end face of the first end 15 of the housing 10 is equal to the distance from the heating element 20 to the end face of the second end 17 of the housing 10. In this way, the degree of heating of the aerosol-generating substrate 200 near the first end 15 of the mouthpiece portion 30 and the aerosol-generating substrate 200 near the second end 17 of the receptacle portion 10 is close, so that the heat distribution along the length of the heating chamber 11 is more uniform, and the quality of the aerosol produced is improved. The second end 17 is also provided with a through hole 19 communicating with the atmosphere so that an air flow can flow inside the aerosol-generating assembly 100 for delivering the aerosol to the user.

Referring to fig. 1, 3 and 5, in some embodiments, the ratio of the distance from the heating element 20 to the end surface of the first end 15 of the accommodating portion 10 to the distance from the heating element 20 to the end surface of the second end 17 of the accommodating portion 10 is in the range of [0.9,1.1]. If the ratio of the distance from the heating element 20 to the end face of the first end 15 of the housing portion 10 to the distance from the heating element 20 to the end face of the second end 17 of the housing portion 10 is less than 1, the heating element 20 is closer to the end face of the first end 15; if the ratio of the distance from the heating element 20 to the end face of the first end 15 of the housing portion 10 to the distance from the heating element 20 to the end face of the second end 17 of the housing portion 10 is greater than 1, the heating element 20 is closer to the end face of the second end 17. In the case where the ratio of the distance from the heating element 20 to the end face of the first end 15 of the housing portion 10 to the distance from the heating element 20 to the end face of the second end 17 of the housing portion 10 is in the range of [0.9,1.1], even if the heating element 20 is closer to the first end 15 or closer to the second end 17, the degree of heating of the aerosol-generating substrate 200 near the first end 15 of the housing portion 10 and the aerosol-generating substrate 200 near the second end 17 of the mouthpiece portion 30 is relatively close, and the heat distribution along the length direction of the heating chamber 11 is relatively uniform, so that a high-quality aerosol can be generated.

Referring to fig. 1, in some embodiments, the suction nozzle portion 30 includes a cooling section 31 and a filtering section 32, and the cooling section 31 connects the accommodating portion 10 and the filtering section 32. The cooling section 31 communicates with both the heating chamber 11 and the filter section 32, and a user may inhale through the filter section 32 to draw aerosol into the heating chamber 11. The aerosol drops in temperature as it passes through the cool down section 31 to avoid inhalation of the scalding aerosol by the user. The filter section 32 can filter a portion of the impurities, avoiding the user from sucking the impurities into the inlet.

In some embodiments, filter segment 32 includes a porous body, such as cotton, porous ceramic, and the like, without limitation. The porous body is favorable for the circulation of gas and aerosol, has better adsorption capacity, is favorable for adsorbing impurities in the airflow, and avoids the impurities from being sucked into the inlet by a user.

In some embodiments, the cooling section 31 includes a polylactic acid material having a better heat absorbing capacity to ensure that the temperature of the aerosol after passing through the cooling section is not too hot.

Referring to fig. 1, in some embodiments, the heating element 20 is manufactured through quenching or aging treatment to have a certain strength, so as to ensure the reliability of the use of the heating element 20.

In some embodiments, the heater 20 is provided with a plating or coating on the surface to protect the heater 20 from corrosion.

In some embodiments, the heating element 20 is a metallic ferromagnetic material, for example, the heating element 20 is a material such as iron alloy, cobalt alloy, nickel alloy, stainless steel, etc., without limitation. The heating body 20 is used to be coupled with a coil of an external device to generate heat. It will be appreciated that the coil may generate an alternating magnetic field in which the ferromagnetic material may generate eddy currents, whereby heat may be generated for heating the aerosol-generating substrate. In this way, the power supply is not required to supply power to the heating element 20 in the aerosol-generating module 100, so that the components of the aerosol-generating module 100 can be reduced, the cost of the aerosol-generating module 100 can be reduced, and the size of the aerosol-generating module 100 can be reduced.

The heating assembly 300 is used to heat the aerosol-generating assembly 100 to generate an aerosol.

In some embodiments, the aerosol-generating device 1000 further comprises a battery assembly 400, the battery assembly 400 being configured to power the coil 302 in a predetermined pattern. In one embodiment, the battery assembly 400 includes a control device and a battery, the control device controlling the battery to output a current or voltage of a corresponding power according to a preset pattern. For example, the preset modes include a high temperature mode and a low temperature mode, and in the case where the aerosol-generating device 1000 is set to the high temperature mode, the control device controls the battery to output a current of the first power; in case the aerosol-generating device 1000 is set to the low temperature mode, the control means controls the battery to output a current of a second power, the second power being smaller than the first power.

The heating assembly 300 includes a housing 301 and a coil 302. The housing 301 is provided with a chamber 303, the coil 302 is wound around the outside of the chamber 303, and an alternating magnetic field can be generated under the control of the battery assembly 400, and when the housing 10 of the aerosol-generating assembly 100 is inserted into the chamber, eddy currents are generated in the heat-generating body 20, thereby causing the heat-generating body 20 to generate heat. By adjusting the number of coils 302, the power of the coils 302, and other parameters, the heating temperature of the heating body 20 can be accurately controlled, so as to accurately control the baking temperature of the aerosol-generating substrate 200, and facilitate improving the quality of the generated aerosol.

In summary, the aerosol-generating device 1000 and the heating element 20 of the aerosol-generating assembly 100 according to the embodiments of the present application encircle the central axis 12 of the accommodating portion 10 and are spaced from the side wall 112 of the heating cavity 11, so that the distance from the heating element 20 to the central position of the heating cavity 11 and the distance from the heating element 20 to the edge position of the heating cavity 11 are relatively uniform, so that the heating element 20 can bake the aerosol-generating substrate 200 more uniformly, and the quality of the generated aerosol is improved.
