In order to overcome the problem that harmful substances are generated by burning cigarettes, cigarette substitutes such as a heating non-burning device and the like are provided. The tobacco product is placed in a heat non-combustion device, and nicotine and other compounds in the tobacco product are released under the condition of heat non-combustion to form smoke for smoking.

In the related art of the heating non-combustion device, there are two heating modes, namely, central heating and peripheral heating, in the central heating mode, a resistance heating sheet or a resistance heating needle and the like are inserted into the tobacco from the center of the bottom of the tobacco, and the center of the tobacco is heated first; in the peripheral heating mode, the tobacco product is accommodated in the heat conduction cavity, the resistance heating wire positioned on the outer wall of the heat conduction cavity generates heat after being electrified and transmits the heat to the tobacco product through the heat conduction cavity, and the periphery of the tobacco product is heated firstly. The central heating mode has a problem that the temperature distribution is not uniform after the tobacco product is heated, the temperature difference from the top to the bottom is large and reaches about 100 ℃, so that the tobacco is not sufficiently baked, the tobacco waste is large, and simultaneously, the tobacco is easy to have scorched flavor.

However, the insulating cloth has poor heat conduction capability, heat cannot be rapidly and effectively transmitted to the heat conduction cavity, and the problem of low heat conduction efficiency exists. And because the heat conductivity of the insulating cloth is poor, the temperature of the part of the heat conduction cavity opposite to the entity area of the resistance heating element is fast, and the temperature of the part of the heat conduction cavity opposite to the hollow area of the resistance heating element is slow, namely the traditional non-combustion heating device has the problem of uneven heat conduction.

The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1 and 2, a heating non-combustion device 10 according to an embodiment of the present invention includes a heating element 12 and a main unit 14, wherein a battery 800 of the main unit 14 can supply power to the heating element 12, and the heating element 12 can accommodate tobacco products. When the battery 100 supplies power to the heating element 12, the heating element 12 heats and cures the tobacco product contained therein, so that compounds such as nicotine in the tobacco product are released to form smoke for smoking. Wherein the tobacco product is received in the heating element 12, i.e. the non-heating combustion device 10 is heated by ambient heating. The tobacco product can be traditional cigarette (cigarette) or cut tobacco.

As shown in fig. 2 to 5, the heating element 12 includes a heat conducting cavity 100, a carbon-based film 200, and a resistance heating element 300. The heat-conducting cavity 100 is used for accommodating tobacco products, and the tobacco products can be inserted into the heat-conducting cavity 100 from the opening end of the heat-conducting cavity 100. The carbon-based film 200 has flexibility, insulation property and thermal conductivity, and the carbon-based film 200 is wound on the outer wall 100a of the thermal conductive cavity 100. The resistance heating element 300 is provided on the carbon-based film 200, and the resistance heating element 300 includes a first electrode 310 and a second electrode 320, the first electrode 310 being for electrical connection with one of the positive electrode and the negative electrode of the battery 800, and the second electrode 320 being for electrical connection with the other of the positive electrode and the negative electrode of the battery 800.

In the heating element 12, the carbon-based film 200 having flexibility, insulation property, and thermal conductivity is provided to realize the winding, insulation, and thermal conductivity. Since the carbon-based film 200 has a high thermal conductivity and a high thermal conductivity, when the resistance heater 300 is powered on to generate heat, the heat can be rapidly and effectively transmitted to the thermal conductive cavity 100 through the carbon-based film 200, i.e., the heating element 12 has a high thermal conductivity. Moreover, since the carbon-based film 200 has a strong thermal conductivity, each region of the entire carbon-based film 200 can be heated substantially simultaneously, so that each region of the thermal conductive cavity 100 is heated simultaneously, i.e., the heating element 12 has a uniform thermal conductivity.

In some embodiments, the heat conducting cavity 100 is a stainless steel cavity or a copper cavity or the like with strong heat conducting capability. In this manner, heat from the thermally conductive cavity 100 can be quickly transferred to the smoking article. In some embodiments, the thermally conductive cavity 100 is cylindrical. Thus, the carbon-based film 200 is more conveniently wound on the heat conducting cavity 100.

In some embodiments, carbon-based film 200 includes an insulating layer 210, a carbon-based thermally conductive layer 220, and an adhesive layer 230, which are sequentially stacked. The carbon-based film 200 is adhered to the outer wall 100a of the heat conductive cavity 100 by the adhesive layer 230. Thus, the carbon-based film 200 is easily fixed on the heat conductive cavity 100.

In the heating non-combustion device 10, different tobacco products have different heating temperatures, and some tobacco products have lower heating temperatures, for example, some self-made tobacco products have a heating temperature of 150 ℃ to 200 ℃, and some tobacco products have higher heating temperatures, for example, Chinese traditional cigarettes have a heating temperature of 250 ℃ to 300 ℃. In some embodiments, the insulating layer 210 is a high heat resistance type insulating layer. Specifically, in some embodiments, the insulating layer 210 is a Polyimide (PI) layer or a polytetrafluoroethylene (ptfe) layer.

In some embodiments, the tie layer 230 is an acrylic layer. In other embodiments, the insulating layer 210 and the adhesive layer 230 may be the same material, and in this case, the insulating layer 210 may also be an acrylic layer.

In some embodiments, the carbon-based film 200 has a thermal conductivity of 600W/m · K or more.

The thermal conductivity of the graphene thermal conductive layer is typically greater than that of the graphite thermal conductive layer. In some embodiments, the thermal conductivity of the carbon-based film 200 is greater than or equal to 1000W/m · K, and the carbon-based thermal conductive layer 220 is a graphene thermal conductive layer or a composite layer of the graphite thermal conductive layer and the graphene thermal conductive layer.

In some embodiments, the carbon-based film 200 has a thickness of 0.05 to 0.15mm, the insulating layer 210 has a thickness of 0.01 to 0.05mm, and the adhesive layer 230 has a thickness of 0.005 to 0.05 mm.

In some embodiments, resistive heater 300 is in the form of a mesh. In other embodiments, the resistive heating element 300 may have a spiral shape, and the resistive heating element 300 may have an irregular shape formed by thick-film printing.

In some embodiments, the thermally conductive cavity 100 includes opposing first and second ends 102, 104, the first end 102 being configured for insertion of a smoking article into the thermally conductive cavity 100. The number of the resistance heating elements 300 is plural, and the plural resistance heating elements 300 are arranged along the direction from the first end 102 to the second end 104 of the heat conducting cavity 100. The plurality of resistance heating bodies 300 are arranged, so that tobacco products can be heated in a segmented mode. Specifically, the number of the resistance heat-generating bodies 300 is two, and each resistance heat-generating body 300 is electrically connected to the battery 800, and may be independently in a heating or non-heating state. When the smoking starts, the resistance heating element 300 closest to the second end 104 of the heat conducting cavity 100 may be controlled to heat first, and after the part of the tobacco product corresponding to the resistance heating element 300 is smoked, the resistance heating element 300 closest to the second end 104 of the heat conducting cavity 100 may be controlled to heat, and so on. In some embodiments, the number of the resistance heat-generating bodies 300 is 2 to 4.

In some embodiments, the resistance heating element 300 further includes a grid body 330, the grid body 330 extends along the circumferential direction of the heat conducting cavity 100, and two ends of the grid body 330 are spaced in the circumferential direction and form the gap 302. That is, the grid body 330 is a ring structure with the gap 302. Two ends of the grid body 330 are electrically connected to the first electrode 310 and the second electrode 320, respectively.

The notches 302 of the plurality of resistance heating elements 300 are sequentially arranged in the direction from the first end 102 to the second end 104, and the width of the notches 302 in the circumferential direction is gradually increased, so that the first electrodes 310 and the second electrodes 320 of the plurality of resistance heating elements 300 can be insulated from each other at intervals when extending and leading out towards the second end 104. Thus, it is very convenient for the plurality of resistance heating elements 300 to be electrically connected to the battery 800 after being extended and drawn from the second end 104.

In some embodiments, the heat conducting chamber 100 further comprises an electrode fixing member 400, wherein the electrode fixing member 400 is wound on the outer wall of the resistance heating element 300 and is used for protecting the first electrode 310 and the second electrode 320 of the plurality of resistance heating elements 300, so that the first electrode 310 and the second electrode 320 of the plurality of resistance heating elements 300 are kept to be insulated from each other. Since the first electrode 310 and the second electrode 320 are both conductive lines, they are easily deformed by an external force, and thus adjacent electrodes are changed from a spaced state to a contact state, thereby causing a short circuit. The electrode fixing member 400 is provided to effectively protect the first electrode 310 and the second electrode 320 of the plurality of resistance heating elements 300 and prevent the adjacent electrodes from being in contact with each other from being in a spaced state.

In some embodiments, the electrode holder 400 includes a plastic substrate and a glue layer disposed on the plastic substrate, wherein the glue layer is closer to the thermal conductive cavity 100 than the plastic substrate.

In some embodiments, the number of the first electrodes 310 is one, one first electrode 310 is electrically connected to a plurality of grid bodies 330, and the number of the second electrodes 320 is the same as the number of the grid bodies 330, and the first electrodes are electrically connected in a one-to-one correspondence. In this manner, the notch 302 is prevented from being excessively wide in the circumferential direction, and the interface for electrical connection with the battery 800 is also reduced.

In some embodiments, the heating assembly 12 further comprises a temperature sensor 500, and the temperature sensor 500 is used for acquiring temperature information of the heat conducting cavity 100, i.e. the heated tobacco product.

In some embodiments, the carbon-based film 200 includes a first region 202 and a second region 204, the resistance heating element 300 is disposed in the first region 202, and the temperature sensor 500 is disposed in the second region 204. That is, the resistance heat-generating body 300 and the temperature sensor 500 are located in different regions of the carbon-based film 200, and taking the view angle shown in fig. 2 as an example, the length of the resistance heat-generating body 300 is smaller than the length of the carbon-based film 200, the end region of the carbon-based film 200 not covered with the resistance heat-generating body 300 is the second region 204, and the middle region of the carbon-based film 200 covered with the resistance heat-generating body 300 is the first region 202. Since the carbon-based film 200 has a strong thermal conductivity, the temperature of each region of the entire carbon-based film 200 can be raised substantially simultaneously, so that each region of the thermal conductive cavity 100 is raised substantially simultaneously, and the final temperature of the thermal conductive cavity 100 is substantially the same as the final temperature of the carbon-based film 200. The temperature sensor 500 is disposed in the second region 204, so that the final temperature of the heat conducting cavity 100 can be accurately obtained.

In some embodiments, as shown in fig. 6, the number of the carbon-based films 200 is two, i.e., the first carbon-based film 200a and the second carbon-based film 200 b. The heat conductive cavity 100, the first carbon-based film 200a, the resistance heating element 300, and the second carbon-based film 200b are sequentially arranged from the inside to the outside, and the temperature sensor 500 is disposed on the insulating layer 210 of the second carbon-based film 200 b. Since the carbon-based films 200 have high thermal conductivity, the final temperatures of the first carbon-based film 200a and the second carbon-based film 200b are substantially the same, and the final temperature of the thermal conductive cavity 100 is substantially the same as the final temperature of the first carbon-based film 200a, the final temperature of the thermal conductive cavity 100 can be accurately obtained by disposing the temperature sensor 500 on the second carbon-based film 200 b. In addition, when the number of the carbon-based films 200 is two, the second carbon-based film 200b can effectively protect the first electrode 310 and the second electrode 320 of the plurality of resistive heating elements 300 from being changed from the spaced state to the contact state. At this time, the second carbon-based film 200b also functions as the electrode fixing member 400.

In some embodiments, as shown in fig. 1 and fig. 2, the heating assembly 12 further includes a heat insulation sleeve 600, the heat insulation sleeve 600 is sleeved outside the resistance heater 300, and the resistance heater 300 is located between the heat insulation sleeve 600 and the heat conducting cavity 100. The heat insulation sleeve 600 can prevent the heat generated by the resistance heating element 300 from being conducted to other elements such as the shell 700 of the host 14, and can also effectively prevent the heat from being dissipated, thereby improving the utilization rate of the heat.

In some embodiments, the host 14 includes a housing 700, a battery 800, a smoke channel 900, and a filter 910.

The housing 700 defines a heating chamber 702, and the heating assembly 12 is received in the heating chamber 702 and detachably connected to the heating chamber 702. In this manner, replacement and maintenance of the heating assembly 12 is greatly facilitated. The housing 700 is provided with a cover 704 hinged to the housing 700, and the heating chamber 702 can be opened and closed by rotating the cover 704. Thus, impurities can be prevented from entering the heat conducting chamber 100 and the heating chamber 702. In some embodiments, there is a gap between the cover 704 and the housing 700 in the closed heating chamber 702 state, so that the external air can enter the heat-conducting cavity 100 through the gap. It is understood that in other embodiments, air holes communicating with the heating chamber 702 may be directly formed on the housing 700, so that the outside air can enter the heating chamber 702 through the air holes and then enter the heat-conducting chamber 100 through the heating chamber 702.

The battery 800 is disposed in the case 700, and the first electrode 310 and the second electrode 320 of the resistance heating element 300 are electrically connected to the positive electrode and the negative electrode of the battery 800, respectively.

The smoke channel 900 and the filter 910 are disposed in the housing 700, and the filter 910 connects the heat-conducting cavity 100 and the smoke channel 900. When smoking the cigarette bullet, the air can get into in the heat conduction cavity 100 through the gap between apron 704 and shell 700, and the smog that the heating cigarette bullet produced mixes with the air back, filters some large particulate matters through filtering piece 910 earlier, promotes the smog taste, and the rethread smog passageway 900 is transmitted to heating and is not outside burner 10, supplies the user to inhale.

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.

It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
