As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Referring to figures 1, 2 and 3, a heated non-burning smoking article 10 is disclosed which can be used to insert an aerosol-generating substrate 20, such as a cigarette, and to heat the aerosol-generating substrate 20 to a temperature such that the aerosol-generating substrate 20 is at a temperature at which it does not burn but is capable of generating an aerosol, such as smoke emitted from tobacco for consumption by a user, using an internal heating module 11. In some embodiments, the aerosol-generating substrate 20 is a conventional cigarette. In other embodiments, the aerosol-generating substrate 20 may be a specially prepared cartridge, as the invention is not limited in this respect.
In one embodiment, the non-burning heating smoking article 10 is substantially in the form of an oval cylinder, i.e. the non-burning heating smoking article 10 has a substantially oval cross-section with an opening 10a at one end for the aerosol generating substrate 20 to enter and exit and a mouthpiece 10b at the opposite end. The user may insert the aerosol-generating substrate 20 from the opening 10a and, once the aerosol-generating substrate 20 is heated, by heating the interior of the non-burning smoking article 10, the user may inhale smoke through the mouthpiece 10 b. In other embodiments, the heated non-burning smoking article 10 may be cylindrical, i.e., the heated non-burning smoking article 10 may be circular in cross-section. In other embodiments, the heated non-burning smoking article 10 may also have other shapes.
Referring to fig. 2 and 3, the heating non-combustion smoking set 10 may further include a housing 12 and a power source (not shown), and the heating module 11 includes a circuit board 111, a heating element 113, a lead 115, and a heat recovery element 117. The heating module 11 and the power supply are respectively installed in the housing 12, and the housing 12 plays a role in bearing and protecting. The heating module 11 and the power source are electrically connected to the circuit board 111. The power supply can supply power to the circuit board 111 and the heating module 11, and the power supply can be a battery such as a lithium battery which can be repeatedly charged and discharged. The appearance of the heated non-burning smoking article 10 is primarily presented by the outer shell 12.
A mouthpiece 10b and an opening 10a for insertion and removal of an aerosol-generating substrate 20 (e.g. a cigarette) are both provided in the outer housing 12. The housing 12 may also include externally exposed buttons and/or indicator lights that may be used to control the operating conditions of the heated non-burning smoking article 10. For example, pressing a key may switch on the control circuitry, using the power source to power the heating module 11 and heat the aerosol-generating substrate 20. The key may be a physical key or a virtual key, which is not limited in the present invention. The indicator light may be an LED light that may be used to indicate the operating status of the heating non-burning smoking article 10, and the indicator light may be default.
Referring to fig. 2 and 3, the heating element 113 is used to heat the aerosol-generating substrate 20. In some embodiments, the heating assembly 113 comprises a heat pipe 1131 and a heat generating body 1133, the heat pipe 1131 having an aerosol generating substrate 20 containing atomizing channel 113a, the heat generating body 1133 being arranged at the periphery of the heat pipe 1131 and being electrically connected to a power source by means of wires 115. It is to be understood that the electrical connection of the lead 115 to the power supply is not limited to the direct connection of the heating element 1133 to the power supply through the lead 115. The lead 115 may also be connected to an intermediate electronic device, which in turn is connected to a power source via the intermediate electronic device, which may also be used to electrically connect the heating element 1133 to the power source. In the embodiment of the present invention, one end of the lead 115 is connected to the heating element 1133, the other end of the lead 115 is connected to the circuit board 111, and the circuit board 111 is electrically connected to the power supply through another circuit, which also realizes the electrical connection between the heating element 1133 and the power supply.
The heat pipes 1131 may be made of an aluminum alloy, a heat conducting ceramic, or the like, and may have a cylindrical shape, and after the aerosol-generating substrate 20 is inserted into the atomizing channel 113a, at least a part of the surface of the aerosol-generating substrate 20 may contact the heat pipes 1131. The heating element 1133 may be made of a metal conductor, and when the heating element 1133 is energized, it generates heat, and transfers the heat to the aerosol-generating substrate 20 through the heat pipe 1131, thereby baking the aerosol-generating substrate 20.
In some embodiments, heat-generating element 1133 may be printed on the outer circumferential surface of heat transfer pipe 1131, and may be in an open loop shape, a closed loop shape, or a spiral shape. The heating element 1133 with such a structure can form a relatively large contact area with the heat conduction pipe 1131 to improve heating and heat conduction efficiency, and the heating element 1133 has a simple structure and occupies a small space, thereby being beneficial to the miniaturization and lightweight design of the heating non-combustion smoking set 10.
Referring to fig. 4 and 5, in other embodiments, heat-generating body 1133 may be a steel sheet or other metal heating sheet, etc., which may be sleeved with heat pipe 1131. The heating element 1133, the heating element 1133 and the heat pipe 1131 with the structure can be manufactured into universal parts and then assembled and molded, and the processing and the assembly are convenient. For example, in the embodiment shown in fig. 5, the heating element 1133 has an open ring shape, one side of the opening can be used for connecting to the cathode of the power supply, and the other side of the opening can be used for connecting to the anode of the power supply.
In some embodiments, the heating assembly 113 may include two or more heating elements 1133, the two or more heating elements 1133 are disposed at intervals on the heat conducting pipe 1131, and each heating element 1133 is correspondingly connected with the conducting wire 115. Each heating element 1133 may be independently energized to generate heat to provide multi-stage heating of the aerosol-generating substrate 20 to improve the mouth feel of the smoke. Of course, in this embodiment, a plurality of heat transfer pipes 1131 may be provided in correspondence, and a plurality of heat transfer pipes 1131 may be provided in one-to-one correspondence with a plurality of heat generators 1133.
Of course, in other embodiments, the heating element 1133 may be provided in a single-stage structure, and the heat transfer pipe 1131 may be provided in a single-stage structure or in a divided structure, that is, the single-stage heating element 1133 is provided with the single-stage or divided heat transfer pipe 1131 to constitute the heating unit 113.
With continued reference to fig. 3, the lead 115 includes a first end 1151 and a second end 1153, the first end 1151 is connected to the heating element 1133 of the heating assembly 113, and the second end 1153 is used for electrical connection with a power source. Heat recovery member 117 is disposed in electrically insulated contact with at least a portion of conductive line 115 between first and second ends 1151, 1153 to absorb heat from conductive line 115.
In the embodiment in which the heating body 1133 is of a one-piece structure, the heating body 1133 may be electrically connected to the anode of the power supply through an anode lead and connected to the cathode of the power supply through a cathode lead, and at least one of the cathode lead and the anode lead is disposed in electrically insulated contact with the heat recovery member 117 to absorb heat of the lead 115 by the heat recovery member 117.
In the embodiment in which the heat generating elements 1133 and/or the heat transfer tubes 1131 are provided in plurality, the lead 115 to which at least one heat generating element 1133 is connected is provided in electrical insulation contact with the heat recovery member 117, that is, the heat recovery member 117 can absorb the heat of the lead 115.
It is understood that, in the embodiment of the present invention, the lead 115 does not distinguish between the anode lead and the cathode lead, and at least a portion of at least one of the anode lead and the cathode lead is disposed in electrically insulated contact with the heat recovery member 117 to recover heat of the lead 115. The metal conductor of the lead 115 may be copper, silver, or the like, and in the present embodiment, the metal conductor of the lead 115 is silver, and the resistance of the lead 115 is relatively small.
Taking the example where two heating elements 1133 and two heat pipes 1131 are provided, the two heat pipes 1131 and the two heating elements 1133 are provided in one-to-one correspondence, so as to heat the aerosol-generating substrate 20 in a segmented manner. The two heating elements 1133 are electrically connected to a power source through wires 115, respectively, and the wires 115 correspondingly connected to the two heating elements 1133 can be in electrical insulation contact with the heat recovery member 117. Alternatively, the lead 115 connected to one of the heating elements 1133 is provided in electrical insulation contact with the heat recovery member 117, and the lead 115 connected to the other heating element 1133 is not provided in electrical insulation contact with the heat recovery member 117. In the embodiment in which three or more heating elements 1133 and heat transfer tubes 1131 are provided, they may be provided in a similar manner, and will not be described again here.
Referring to fig. 3, the heat recovery member 117 may be substantially cylindrical, and is opened with an air flow passage 117a (refer to fig. 6), and the air flow passage 117a communicates with the atomization passage 113 a. In some embodiments, the heating assembly 113 may have an inlet side for ambient air to enter the nebulizing channel 113a, and the heat recovery member 117 is disposed at the inlet side of the nebulizing channel 113 a. With reference to fig. 1, the inlet side may be simply understood as the end of the heating element 113 closer to the opening 10a, and may also be understood as the end of the heating element 113 further away from the mouthpiece 10 b. Alternatively, the inlet side of the heating element 113 is located closer to the opening 10a than the mouthpiece 10 b. Taking the aerosol-generating substrate 20 as an example of a cigarette, the cigarette is inserted into the aperture 10a, further into the airflow channel 117a, and into the atomising channel 113a from the inlet side, from the end remote from the filter. In some embodiments, after the cigarette is inserted into the heated non-burning smoking set 10, the tobacco of the cigarette may be located in the atomizing channel 113a, or a small portion of the tobacco may be located in the air flow channel 117 a.
It will be appreciated that the heating element 113 may have an outlet side disposed opposite an inlet side, the outlet side being closer to the mouthpiece 10b than the inlet side, or alternatively, the outlet side being further from the aperture 10a than the inlet side. In other embodiments, the aerosol-generating substrate 20 may also be inserted into the nebulization channel 113a from the outlet side. For example, in using the heating non-burning smoking article 10, the user may remove the mouthpiece 10b, insert the cigarette into the nebulizing channel 113a from the outlet side of the nebulizing channel 113a, and then mount the mouthpiece 10b to the housing 12.
In the related art, when the smoking set 10 is not heated and operated, the heating element 1133 of the heating module 113 is energized to generate heat, and the heat is transferred to the aerosol-generating substrate 20 through the heat pipe 1131, so that the aerosol-generating substrate 20 is atomized in a heated but non-combusted state to generate aerosol for a user to inhale. Because the heating element 1133 is connected to the control circuit through the wire 115 and electrically connected to the power supply, the metal conductor in the wire 115 is a good conductor of heat, when the heating element 1133 is powered on to generate heat, the heat generated by the heating element 1133 is conducted to the control circuit or the power supply through the wire 115, which not only causes the heat generated by the heating element 1133 to be lost, but also causes the temperature rise of the electronic components of the control circuit or the power supply to be too high, thereby shortening the service life of the electronic components of the control circuit or the power supply.
In the solution of the present invention, since the first end 1151 of the wire 115 is connected to the heating element 1133 of the heating assembly 113, the second end 1153 is used for electrical connection with a power supply, and at least a portion of the wire 115 between the first end 1151 and the second end 1153 is disposed in electrically insulated contact with the heat recovery member 117. During the process of powering on the heating assembly 113 and generating heat, at least a portion of the heat conducted from the heating assembly 113 to the leads 115 may be absorbed by the heat recovery member 117, and the heat absorbed by the heat recovery member 117 may be used to directly or indirectly heat the aerosol-generating substrate 20 to improve energy efficiency. Of course, it will be appreciated that at least a portion of the heat generated during energisation of the leads 115 may also be absorbed by the heat recovery member 117, and this portion of the heat may also be used to heat the aerosol-generating substrate 20, either directly or indirectly, to improve energy utilisation.
The following description will take as an example the aerosol-generating substrate 20 as a cigarette and inserted into the nebulization channel 113a from the aperture 10 a.
In some embodiments, after the cigarette is inserted into the non-combustion heating smoking set 10, the cigarette is accommodated in the airflow channel 117a and the atomization channel 113a, and a small part of the cut tobacco of the cigarette is accommodated in the airflow channel 117a, and a certain gap may exist between the circumferential direction of the cigarette and the wall surface of the airflow channel 117a, so as to facilitate the air flowing in the gap and reduce the resistance of the air sucked into the atomization channel 113 a. In this embodiment, the heat absorbed by the heat recovery member 117 from the conducting wires 115 can heat the air in the gap in the circumferential direction of the cigarette, and the heated air can further heat the cut tobacco in the cigarette, that is, the heat absorbed by the heat recovery member 117 is indirectly used for heating the cut tobacco, so as to improve the utilization rate of energy.
In other embodiments, after the cigarette is inserted into the heated non-burning smoking article 10, the cigarette is received in the airflow channel 117a and the atomizing channel 113a and a small portion of the cut tobacco of the cigarette is received in the airflow channel 117a, and the circumference of the cigarette is in contact with the wall surface of the airflow channel 117a and substantially no gap exists. In this embodiment, the heat absorbed by the heat recovery member 117 from the conducting wire 115 can directly heat the cigarette, that is, the heat absorbed by the heat recovery member 117 is directly used for heating the cut tobacco, so as to improve the utilization rate of energy.
In other embodiments, after the cigarette is inserted into the heating non-combustion smoking set 10, the cigarette is accommodated in the airflow channel 117a and the atomization channel 113a, and the whole part of the tobacco shred position of the cigarette is accommodated in the atomization channel 113a, a gap can exist between the circumferential direction of the cigarette and the wall surface of the airflow channel 117a, and the heat absorbed by the heat recovery part 117 from the conducting wire 115 can preheat the air inside and outside the filter tip of the cigarette, so as to improve the temperature of the air entering the tobacco shred, further improve the efficiency of heating the cigarette, and improve the utilization rate of energy. Of course, in this embodiment, there may be no gap between the circumferential direction of the cigarette and the wall surface of the airflow channel 117a, and the heat absorbed by the heat recovery member 117 from the conducting wire 115 may also preheat the air passing through the filter of the cigarette, so as to raise the temperature of the air entering the tobacco shred, and further raise the efficiency of heating the cigarette, and raise the utilization rate of energy.
It will be appreciated that in embodiments of the invention, at least a portion of the heat generated by the circuit board 111 or the electronic components of the power supply may also be transferred to the heat recovery member 117 via the wires 115 for direct or indirect heating of the aerosol-generating substrate 20 to increase the efficiency of the energy source, since at least some of the wires 115 between the first and second ends 1151, 1153 are arranged in electrically insulated contact with the heat recovery member 117.
Of course, in other embodiments, the heat absorbed by the heat recovery member 117 from the conducting wires 115 can also be directly dissipated into the external air, for example, through the design of the heat dissipation flow channel or the design of the heat dissipation material, so that the heat recovery member 117 can absorb the heat from the conducting wires 115 and dissipate the heat into the external air relatively quickly, thereby reducing the heat conducted to the circuit board 111 or the power supply through the conducting wires 115, and preventing the power supply or the electronic components of the circuit board 111 from being raised too high, so as to protect the power supply or the electronic components of the circuit board 111.
Further, in embodiments in which the aerosol-generating substrate 20 is inserted into the nebulization channel 113a from the aperture 10a, the walls of the airflow channel 117a may transition smoothly with the walls of the nebulization channel 113a, which may prevent jamming of the aerosol-generating substrate 20 during insertion into the nebulization channel 113a, thereby protecting the aerosol-generating substrate 20. Taking the embodiment in which both the heat pipe 1131 and the heating element 1133 are cylindrical, the inner diameter of the heat pipe 1131 and the inner diameter of the heating element 1133 may be equal, the heat pipe 1131 and the heating element 1133 may be bonded or welded or connected as a whole by other intermediate members, and the connection position of the two may be processed to realize smooth transition, that is, the surface at the connection position of the two, the wall surface of the airflow channel 117a and the wall surface of the atomizing channel 113a are continuous smooth curved surfaces, so as to prevent the aerosol-generating substrate 20 from being stuck at the connection position of the two.
Of course, it is understood that the heat recovery member 117 does not have to be cylindrical, and the heat recovery member 117 may take other structures because it absorbs the heat of the wires 115 and prevents the heat of the heating assembly 113 from being transferred to the circuit board 111 or the power source. For example, the heat recovery member 117 may have an arc-shaped sheet shape, and the cross-sectional profile thereof may have a major arc shape, a minor arc shape, or a semicircular shape. In this embodiment, the inner diameter of heat recovery member 117 may be equal to the inner diameter of heat conduction pipe 1131, so as to realize smooth transition between the wall surface of airflow channel 117a and the wall surface of atomization channel 113 a.
It is understood that the inner diameter of heat recovery member 117 is equal to the inner diameter of heat conduction pipe 1131, considering the existence of engineering error, and it is not understood that the inner diameters are strictly equal. In the installation process of heat recovery member 117 and heat transfer pipe 1131, it is considered that the inner diameters of both are equal by only making the values of both within a reasonable engineering error range.
Of course, in the embodiment where the aerosol-generating substrate 20 is inserted into the atomizing channel 113a from the opening 10a, the heat pipe 1131 and the heat-generating body 1133 may have a spacing in the insertion direction of the aerosol-generating substrate 20, and the spacing may be set relatively small, and the curvature of the wall surface of the air flow channel 117a close to the atomizing channel 113a may be substantially the same as the curvature of the wall surface of the atomizing channel 113a close to the air flow channel 117a, that is, the wall surfaces of the air flow channel 117a and the atomizing channel 113a in the vicinity of the spacing may be regarded as two parts divided from the same continuous smooth curved surface, so as to prevent the aerosol-generating substrate 20 from being stuck at the spacing therebetween during the insertion into the atomizing channel 113 a.
It can be understood that, in the embodiment where the cigarette is inserted into the atomizing channel 113a from the outlet side of the atomizing channel 113a (i.e. the side where the mouthpiece 10b is located), after the cigarette is inserted into the atomizing channel 113a, the cigarette may not enter the air flow channel 117a, and the heat absorbed by the heat recovery member 117 from the conducting wire 115 may also heat the air in the air flow channel 117a, so as to raise the temperature of the air entering the atomizing channel 113a, thereby implementing indirect heating of the cut tobacco, and improving the efficiency of heating the cigarette, thereby improving the utilization rate of energy.
It will be appreciated that the circumference of the aerosol-generating substrate 20 need not be continuously distributed over the heat recovery member 117. For example, in embodiments in which the heat recovery member 117 is in the form of an arcuate sheet and the cross-sectional profile is in the form of a minor arc, the heating module 11 may comprise more than two heat recovery members 117, the more than two heat recovery members 117 being spaced circumferentially of the aerosol-generating substrate 20. In this embodiment, the wire 115 may be wound in a spiral shape, and the heat recovery member 117 is inserted into the space formed by winding the wire 115, that is, the heat recovery member 117 and the wire 115 together enclose to form the airflow channel 117 a. Of course, in the embodiment where the heat recovery member 117 has an arc-shaped sheet shape and the cross section of the heat recovery member 117 has a poor arc shape, a plurality of heat recovery members 117 may be spliced into a tube shape to form the air flow channel 117a, and at least a portion of the wire 115 between the first end 1151 and the second end 1153 may be wound around the heat recovery member 117.
With continued reference to fig. 3, in some embodiments, at least a portion of the wires 115 between the first and second ends 1151, 1153 are wound around an outer surface of the heat recovery member 117. The bonding position of the wire 115 and the heat recovery member 117 can be coated with materials such as heat-conducting silicone grease, so as to improve the heat-conducting efficiency.
Referring to fig. 6 and 7, in other embodiments, the outer surface of the heat recovery member 117 may be formed with a blind groove 117b extending along the circumferential direction thereof, and at least a portion of the wires 115 between the first end 1151 and the second end 1153 are embedded in the blind groove 117b and wound around the heat recovery member 117. By the structural arrangement, on one hand, the installation position of the lead 115 on the heat recovery piece 117 can be limited by the blind groove 117b, and the neatness and the limiting stability of the routing of the lead 115 are ensured; on the other hand, the arrangement of the blind groove 117b can also effectively increase the contact area between the lead 115 and the heat recovery member 117, so as to improve the heat exchange efficiency between the lead 115 and the heat recovery member 117, and further improve the heat recovery efficiency.
Referring to fig. 8 and 9, in other embodiments, the heat recovery member 117 is opened with a through groove 117c extending along a circumferential direction thereof, the through groove 117c extending from an outer surface of the heat recovery member 117 to an inner surface of the heat recovery member 117. At least a portion of the leads 115 between the first and second ends 1151, 1153 are embedded in the channel 117 c. In this arrangement, the wire 115 and the heat recovery member 117 collectively enclose a tubular structure, and it is also contemplated that the wire 115 and the heat recovery member 117 collectively enclose an airflow passage 117 a. On one hand, the through groove 117c can define the installation position of the wire 115 on the heat recovery member 117, so as to ensure the neatness of the routing of the wire 115 and the stability of the limiting; on the other hand, the setting of logical groove 117c can effectively increase the area of contact of wire 115 and heat recovery piece 117, compare in blind groove 117b or the heat recovery's of no groove scheme of heat conduction, thereby because the partly gaseous contact that can inhale air current channel 117a of wire 115 produces the thermal convection effect, this kind of structural arrangement can make the heat recovery of wire 115 have heat conduction and thermal convection two kinds of modes, thereby further promote the heat exchange efficiency between wire 115 and the heat recovery piece 117, and then promoted the efficiency of heat recovery.
In some embodiments, the heat recovery member 117 is made of an insulating and heat conducting material, such as heat conducting silicone or heat conducting silicone grease, and the metal conductor of the wire 115 is disposed in electrically insulating contact with the heat recovery member 117 to conduct heat of the wire 115 to the heat recovery member 117. Of course, in the embodiment where the heat recovery member 117 is made of an insulating and heat conducting material, such as heat conducting silicone or heat conducting silicone grease, the metal conductor of the wire 115 may be coated with an insulating and heat conducting material, and this structure may also achieve the heat conduction of the wire 115 to the heat recovery member 117.
In other embodiments, the heat recovery member 117 may be made of an electrically and thermally conductive material, such as copper or aluminum or graphene, and the metal conductor of the wire 115 may be coated with an insulating and thermally conductive material, which may also achieve the conduction of the heat of the wire 115 to the heat recovery member 117.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
