Abstract
The invention discloses a heating non-combustion type aerosol generating device, which comprises a device main body (1), a containing cylinder (2) positioned in the main body (1) and a heating part (3); the accommodating cylinder (2) has a bottom wall (22); the heating part (3) is provided with a bottom end (32); the bottom end (32) of the heating part (3) is higher than the bottom wall (22) of the accommodating cylinder (2) in vertical height, so that the bottom end (32) of the heating part (3) is higher than the end face of the aerosol-generating substrate side of the aerosol-generating product in vertical height, thereby ensuring that a part of the area of the aerosol-generating substrate bottom end side of the aerosol-generating product is not surrounded by the heating part, thereby ensuring that the temperature of the section is lower, aerosol is hardly generated, and the problem that the section of aerosol condenses and flows out of the bottom wall of the heating pipe after stopping sucking is avoided.

Description
Technical Field
The invention relates to the technical field of production of low-temperature heating non-combustion aerosol generating devices, in particular to a heating non-combustion aerosol generating device and an aerosol generating system comprising the same.
Background
The heating temperature of the heated non-combustible aerosol-generating substrate is generally between 250 and 350 ℃, and compared with the common burning cigarettes, the heated non-combustible aerosol-generating product can greatly reduce the harm of harmful substances in the aerosol-generating substrate to a smoker while keeping the taste of the traditional cigarettes, and does not generate a high-temperature burning and cracking process, thereby reducing the release amount of tar and harmful substances in the aerosol-generating substrate and greatly reducing the harm of second-hand smoke.
Current heating techniques for heating aerosol-generating articles typically comprise resistive or electromagnetic heating, whereas the form of the heating element typically comprises a tubular heating tube or sheet/needle for heating around the aerosol-generating article, and a heating sheet/needle for heating inserted into the aerosol-generating article. For a resistance heating element, it generates heat when passing electricity through a resistance circuit on the heating element to heat the aerosol-generating article, whereas for an electromagnetic heating element, it generates current and heats by inducing a magnetic field to heat the aerosol-generating article. Existing aerosol-generating articles for heating non-combustible comprise a filter segment for inhalation by a user's mouth and an aerosol-generating substrate segment remote from the filter segment, from the end face of which an air stream may enter the aerosol-generating article and exit the end face of the filter segment. This has the problem that, whether the aerosol-generating substrate is heated by the heating tube or by the heating plate/heating, when the user is not sucking, a small amount of cold air still enters the aerosol-generating substrate section through the end face of the aerosol-generating substrate section, a small portion of the aerosol atomized in the aerosol-generating substrate section is condensed against the cold air, forming liquid which flows out of the end face of the aerosol-generating substrate section to contaminate the appliance, and when the user is sucking, the negative pressure of the aerosol-generating substrate section is low to cause the aerosol to flow to the filter section, but when the user is not sucking, the suction force of the user is absent, causing a small portion of the aerosol to flow from the filter section to the direction of the aerosol-generating substrate section under the negative pressure, and when condensed, the liquid is formed to flow out of the end face of the aerosol-generating substrate section to contaminate the appliance.
In addition, in the conventional heating non-combustion type aerosol-generating device for heating an aerosol-generating article by means of a heating tube, the bottom end of the heating tube is generally flush with the bottom end of the aerosol-generating substrate, and the bottom end surface of the heating tube supports the bottom end surface of the aerosol-generating substrate, and at this time, the bottom end (the end far from the filter tip) of the aerosol-generating substrate is heated by the heating tube, so that aerosol generated by atomizing the bottom end of the aerosol-generating substrate section is not sucked until it is sucked, and further, if external air enters from the end surface of the aerosol-generating substrate section, pre-cooling aerosol generated by atomizing the bottom end of the aerosol-generating substrate section is more easily condensed and flows out of the bottom wall of the pollution heating tube.
Thus, avoiding re-condensation of aerosol that has been atomized is an important way to avoid contaminating the appliance.
The present invention has been made to solve the above problems.
Disclosure of Invention
The invention provides a heating non-combustion type aerosol-generating device, which is characterized by comprising a device main body 1, a containing cylinder 2 positioned in the main body 1 and used for containing an aerosol-generating product, and a heating part 3 used for heating the aerosol-generating product to generate aerosol;
the cartridge 2 comprises a top opening 21 for insertion of an aerosol-generating article, and a bottom wall 22 opposite the top opening 21, from which top opening 21 the aerosol-generating article is inserted and housed inside the cartridge 2;

The purpose of defining the height of the bottom end 32 of the heating portion 3 above the bottom wall 22 of the receiving cylinder 2 in vertical height is here that the bottom end 32 of the heating portion 3 is above the end surface of the aerosol-generating article on the side of the aerosol-generating substrate in vertical height when the receiving cylinder 2 is not receiving an aerosol-generating article.
Preferably, the heating part 3 is a heating tube provided separately from the accommodating tube 2, and accommodates the aerosol-generating article together with the accommodating tube 2. That is, the heating tube and the receiving cylinder 2 are two separate components.

That is, the lower part has no heating pipe on the inner side, and the upper part has a heating pipe on the inner side, so that the bottom end of the heating pipe 3 of the present invention is higher than the bottom wall of the accommodating cylinder 2 in vertical height.
Alternatively, the heating tube is coaxially disposed above the receiving cylinder 2, and the bottom end 32 of the heating tube is vertically higher than the top end of the receiving cylinder 2.

The bottom wall 22 of the cartridge 2 may be at least partially sealed to the end face of the aerosol-generating substrate side of the contained aerosol-generating article to prevent or reduce the ingress of gas into the aerosol-generating substrate through the end face of the aerosol-generating substrate side. Here, the bottom wall 22 may be at least partially sealed to the end face on the side of the aerosol-generating substrate, and optionally, when the end face on the side of the aerosol-generating substrate of the housed aerosol-generating article is provided with a seal, at least a portion of the sealing arrangement of the bottom wall 22 to the end face may be omitted or may be retained. However, when the end face of the aerosol-generating substrate side of the housed aerosol-generating article is free of a seal, i.e. gas may pass unhindered through this end face into the aerosol-generating substrate, the bottom wall 22 needs to remain in at least a partially sealed arrangement with this end face.

The arrangement of the heating pipe in the invention can be used for referencing the description of the heating mode and the resistance type heating mode of the electromagnetic heating pipe in the prior art.
A second aspect of the invention provides an aerosol-generating system comprising a heated non-combustion aerosol-generating device according to the first aspect of the invention, and an aerosol-generating article 8.
Preferably, the aerosol-generating article comprises a compact section 81, an aerosol-generating substrate section 82, an airway section 83 and a filter section 84;

the airway segment 83 has an airflow passage 831 extending axially through the airway segment 83;
the axial air permeability of the compact section 81 is less than the axial air permeability of the aerosol-generating substrate section 82. Preferably, the tightness of the tight section 81 is 0, i.e. no gas is allowed to pass axially.
The tight section 81, aerosol-generating substrate section 82, airway section 83 and filter section 84 are each sections of the aerosol-generating article formed by wrapping or are each sections of the aerosol-generating article formed by filling into integrally formed tubes.
Preferably, the bottom end of the heating portion 3 is vertically higher or flush with the junction of the compact section 81 and the aerosol-generating substrate section 82.
Preferably, the compact segments 81 are selected from non-aerosol generating materials selected from, but not limited to, carbon fiber materials, metal diaphragms, ceramics or polymeric materials; the polymer material is selected from, but not limited to, polyethylene, polypropylene, polyvinyl chloride, polyethylene terephthalate or polylactic acid.
Alternatively, the compact segments 81 are of the same material as the aerosol-generating substrate segments 82 and are each selected from an aerosol-generating material, the compact segments 81 having a bulk density greater than the bulk density of the aerosol-generating substrate segments 82. That is, the material of the compact segment 81 and the aerosol-generating substrate segment 82 are identical at this time, both are aerosol-generating materials, but the compactness of both ends is completely inconsistent, and the density of the compact segment 81 is greater than that of the aerosol-generating substrate segment 82. The axial air permeability of the compact section 81 is less than the axial air permeability of the aerosol-generating substrate section 82. When the compact segment 81 is an aerosol-generating material, it may be formed integrally with the aerosol-generating substrate segment 82 in the manufacture of the aerosol-generating substrate and simply manufactured by compacting the process-shaped high-density aerosol-generating substrate segment as the compact segment 81.
Preferably, the airway segment 83 is hollow having a sidewall and a hollow cavity that is an airflow passageway 831 that extends axially through the airway segment 83; the air passage section 83 is cylindrical and is made of acetate fiber material.
Preferably, the side wall of the air passage section 83 also has a side flow aperture 832 therethrough; the axial location of the lateral flow aperture 832 is proximate to the location of the aerosol-generating substrate segment 82 and remote from the location of the filter segment 84; the reason for the closer position to the aerosol-generating substrate segment 82 is that the closer the axial position of the lateral flow aperture 832 is to the aerosol-generating substrate segment 82, the easier it is to extract aerosol from the aerosol-generating substrate segment 82. The number of lateral flow holes 832 may be, but is not limited to, 6-8.
Preferably, the airway segment 83 comprises a first airway segment 833 adjacent to the aerosol-generating substrate segment 82 and a second airway segment 834 adjacent to the filter segment 84; the first air passage section 833 and the second air passage section 834 may be integral or separable.
The cross-sectional area of the air flow passage 831 of the first air passage section 833 is smaller than or equal to or larger than the cross-sectional area of the air flow passage 831 of the second air passage section 834. When the airway segment 83 is hollow, it has side walls and a hollow cavity that is an airflow passage 831 that extends axially through the airway segment 83. The inner diameter of the hollow cavity of the first air passage section 833 is smaller than or equal to or larger than that of the hollow cavity of the second air passage section 834, and at the moment, the joint of the first air passage section 833 and the second air passage section can be a conical inclined plane, a vertical section, a flat angle or a rounded corner structure. When the inner diameter of the hollow cavity of the first air passage section 833 is larger than that of the hollow cavity of the second air passage section 834, the air quantity introduced by the first air passage section 833 is more, the extraction effect on the aerosol is better, and the aerosol quantity is larger. And when the hollow cavity internal diameter of first air flue section 833 is less than the hollow cavity internal diameter of second air flue section 834, second air flue section 834 can assemble more aerosols, and is better to the condensation effect of aerosol, and the aerosol cooling effect is better, is more suitable for the suction.
Preferably, when the heating non-combustion type aerosol-generating device is an electromagnetic heating device, the aerosol-generating substrate segment 82 further has a metal sheet 7 disposed in an axial direction, and the metal sheet 7 in the middle can also sense electromagnetic heat generated by the coil.
Preferably, the airway segment 83 is cylindrical and is made of a material selected from, but not limited to, acetate fiber materials and polymer materials.
The aerosol-generating substrate segment 82 contains an aerosol-generating material therein, which is in the form of particles or filaments.
The form of the aerosol-generating material is merely exemplified here, but the present invention is not limited to the above forms, and any aerosol-generating medium that can generate an aerosol is applicable.
The total length of the aerosol-generating article of the invention may be in the range of 30 to 80mm, with the compact segment being in the range of 2 to 10mm, preferably 5mm, the aerosol-generating substrate segment 82 being 8 to 25mm, preferably 12mm, the airway segment 83 being 10 to 20mm, preferably 15mm, and the filter segment 84 being 8 to 15mm, preferably 10mm.
The above preferred schemes can be freely combined without conflict.
Compared with the prior art, the invention has the following beneficial effects:
1. the heating non-combustion aerosol-generating device of the present invention comprises a device body 1, a housing tube 2, and a heating portion 3; the bottom end 32 of the heating portion 3 is vertically higher than the bottom wall 22 of the accommodating cylinder 2, so that the bottom end 32 of the heating portion 3 is vertically higher than the end face of the aerosol-generating article on the side of the aerosol-generating substrate. This ensures that a partial region of the aerosol-generating substrate at the bottom end of the aerosol-generating article is not surrounded by the heating portion, so that the temperature of this section is low and almost no aerosol is generated, which also avoids the problem that after stopping the suction, the aerosol which is not sucked off of this section condenses and flows out from the end face to contaminate the bottom wall of the heating tube.
2. In a preferred embodiment of the invention, the bottom wall 22 of the cartridge 2 may be at least partially sealed to the end face of the aerosol-generating substrate side of the housed aerosol-generating article to prevent or reduce the ingress of gas into the aerosol-generating substrate through the end face of the aerosol-generating substrate side. It is thereby possible to prevent cold air from entering the aerosol-generating substrate section through the end face of the aerosol-generating substrate section, a small portion of the aerosol atomized in the aerosol-generating substrate section encountering the cold air to be condensed, forming liquid flowing out of the end face of the aerosol-generating substrate section.
3. The heating tube and the receiving cylinder 2 in the present invention may be two separate parts, which are coaxially arranged and may be partially overlapped in the vertical direction or may be two completely separated sections. In addition, the heating pipe and the accommodating tube 2 may be integrated, and the heating portion 3 may be a part of the accommodating tube 2. That is, the portion of the accommodating tube 2 near the tip has a heat generating function, and is configured to serve as both an accommodating tube for accommodating the aerosol-generating article and a heating portion for heating the aerosol-generating article, so that the structure is simpler and the implementation is easier.
4. In a preferred embodiment of the invention, the aerosol-generating article 8 used is provided with a compact segment 81 at the end of the aerosol-generating substrate segment 82 remote from said filter segment 84, whereas the axial air permeability of said compact segment 81 is smaller than the axial air permeability of said aerosol-generating substrate segment 82, whereby air entering said aerosol-generating substrate segment 82 through said compact segment 81 is reduced and prevented, whereby cold air is prevented from entering the aerosol-generating substrate segment through the end face of the aerosol-generating substrate segment, and a small portion of the aerosol atomized in the aerosol-generating substrate segment is condensed against the cold air, forming a liquid flowing out of the end face of the aerosol-generating substrate segment.
4. In the prior art, the end part of the aerosol generating substrate section passes through the air in the sucking process, and the aerosol generating substrate section is in a negative pressure state in the sucking process, so that the problem that the aerosol which is not sucked back flows from the filter section to the aerosol generating substrate section can occur at the moment of stopping sucking.
However, after the compact section is added in front of the aerosol generating substrate section, in the process of sucking by a user, because the external air can hardly enter the aerosol substrate section through the compact section, the negative pressure of the aerosol substrate section can not rise, so that the aerosol can be prevented from flowing back to the aerosol substrate section and flowing out from the end face of the aerosol generating substrate section when the sucking is stopped, and the problem that the aerosol condensate flows out from the end face of the aerosol generating substrate section to pollute an appliance is further solved.
5. In a preferred embodiment, the compact segment 81 is selected from a non-aerosol generating material selected from but not limited to a carbon fiber material, a metal film, a ceramic or a polymeric material, or the compact segment 81 is selected from an aerosol generating material, the compact segment 81 has a density greater than that of the aerosol generating substrate segment 82, the material selection range is wide, in addition, when the compact segment 81 is an aerosol generating material, it may be integrally formed with the aerosol generating substrate segment 82 in the manufacture of the aerosol generating substrate, and the manufacture is simple by compacting the process shape of the high density aerosol generating substrate segment as the compact segment 81.
6. In a preferred embodiment, the side wall of the airway segment 83 also has a side flow aperture 832 therethrough, which is provided to facilitate aerosol extraction to reduce resistance to extraction during extraction.
7. In a preferred embodiment, the axial location of the lateral flow aperture 832 is located close to the location of the aerosol-generating substrate segment 82 and remote from the location of the filter segment 84, the air introduced by the lateral flow aperture having an extraction effect on the aerosol generated by the aerosol-generating substrate segment 82.
8. In a preferred embodiment, the airway segment 83 comprises a first airway segment 833 adjacent to the aerosol-generating substrate segment 82 and a second airway segment 834 adjacent to the filter segment 84. The cross-sectional area of the air flow channel 831 of the first air passage section 833 is smaller than or equal to or larger than the cross-sectional area of the air flow channel 831 of the second air passage section 834; when the airway segment 83 is hollow, it has side walls and a hollow cavity that is an airflow passage 831 that extends axially through the airway segment 83. The hollow cavity inner diameter of the first air passage section 833 is smaller than or equal to or larger than the hollow cavity inner diameter of the second air passage section 834.
When the inner diameter of the hollow cavity of the first air passage section 833 is larger than that of the hollow cavity of the second air passage section 834, the air quantity introduced by the first air passage section 833 is more, the extraction effect on the aerosol is better, and the aerosol quantity is larger.
And when the hollow cavity internal diameter of first air flue section 833 is less than the hollow cavity internal diameter of second air flue section 834, second air flue section 834 can assemble more aerosols, and is better to the condensation effect of aerosol, and the aerosol cooling effect is better, is more suitable for the suction.
