Detailed Description
In order to more clearly illustrate the invention, the invention is further described below with reference to the accompanying drawings.
Fig. 1 and 2 illustrate a heated non-combustion baking apparatus 1 according to some embodiments of the present invention, the heated non-combustion baking apparatus 1 being configured to heat-bake an aerosol-forming substrate 2 removably inserted therein to release an aerosol extract from the aerosol-forming substrate 2 in a non-combustion state. As shown, the aerosol-forming substrate 2 may be a cigarette arranged in a cylindrical shape. Correspondingly, the top of the heated non-combustion baking apparatus 1 is provided with receptacles 10 of a size adapted to the aerosol-forming substrate 2. A receptacle cover 15 may be provided beside the receptacle 10 to cover the receptacle 10 when not in use, preventing foreign matter from entering the receptacle 10, interfering with the use of the heated non-combustion baking apparatus 1.
Referring also to fig. 3, the heated non-combustion toasting device 1 may in some embodiments comprise a housing 11 and heating means 12, a power source 13 and a main board 14 arranged within the housing 11. The heating device 12 is inserted into the insertion hole 10 from the bottom of the insertion hole 10 so that the heating device 12 can be inserted into the aerosol-forming substrate 2 from the bottom end of the aerosol-forming substrate 2 longitudinally while being in close contact with the low-temperature baked aerosol-forming substrate 2 in the aerosol-forming substrate 2 when the aerosol-forming substrate 2 is inserted into the insertion hole 10. Thus, when the heating device 12 is energized to generate heat, the heat can be transferred to the aerosol-forming substrate 2, and the aerosol-forming substrate 2 is heated to emit smoke. The power supply 13 is electrically connected with the heating device 12, and the on-off of the power supply and the heating device is controlled by a switch. The motherboard 14 is used to arrange the associated master circuits.
As shown in fig. 4-6, the heating device 12 may in some embodiments include a conductive substrate 121 and a first insulating layer 122, a conductive trace 123, a first protective layer 124, a second insulating layer 125, and a second protective layer 126 bonded to the conductive substrate 121. The conductive trace 123 may in some embodiments include a first end and a second end for electrical connection with the positive and negative poles, respectively, of the power source 13, wherein the first end is electrically connected with the conductive substrate 121 and the second end is electrically insulated from the conductive substrate 121 so that current can enter the conductive trace 123 from the first end via the conductive substrate 121 and exit the conductive trace 123 from the second end.
The conductive substrate 121 may be made of a metal such as stainless steel or a conductive material such as conductive ceramic in some embodiments, and may have a thickness of 0.4-0.7mm. Referring also to fig. 7, the conductive substrate 121 may be in the form of an elongated sheet in some embodiments, which may include a planar first surface 1211 and a planar second surface 1212 opposite the first surface 1211. The conductive substrate 121 may include a fixing portion 1213 for fixing to the housing 11 and an insertion portion 1214 connected to the fixing portion 1213 in some embodiments. The insertion portion 1214 is for insertion into the aerosol-forming substrate 2 and may comprise a V-shaped tip 1215 to facilitate insertion into the aerosol-forming substrate 2. Both opposite edges of the insertion portion 1214 and both adjacent edges of the tip 1215 may be sharpened to further facilitate insertion into the aerosol-forming substrate 2.
The first insulating layer 122 may be made of one or more materials of glass, ceramic, and polyimide in some embodiments, and is formed on the first surface 1211 of the conductive substrate 121, and a notch 1220 may be provided at one corner of the root portion so that the conductive substrate 121 is exposed outside the first insulating layer 122 at the notch 1220.
The conductive line 123 may include a first heat generating portion 1231 and a second heat generating portion 1232 having a relatively large resistance temperature characteristic, and each of the first heat generating portion 1231 and the second heat generating portion 1232 may be formed on a surface of the first insulating layer 122 by a silk-screen or electroplating method to be electrically insulated from the conductive substrate 121. The first and second heat generating portions 1231 and 1232 may be U-shaped in some embodiments, and the second heat generating portion 1232 is located inside the first heat generating portion 1231. The first and second ends of the first heat generating part 1231 are connected to the first and second ends of the second heat generating part 1232, respectively, such that the first and second heat generating parts 1231 and 1232 are connected in parallel. The first and second heat generating portions 1231, 1232 may be formed of one or more materials of silver, platinum, copper, nickel, and palladium in some embodiments. In some embodiments, temperature measurements may be made with the first heat generating portion 1231 or the second heat generating portion 1232 to better monitor the heat generating temperature.
The first heating part 1231 may include two longitudinal heating arms arranged in parallel at a distance in the length direction of the conductive substrate 121 and a V-shaped heating part connecting the two heating arms together in series at the top end, the root parts of the two longitudinal heating arms forming the first and second ends of the first heating part 1231, respectively. Each heating arm may include a first heating section, a second heating section, and a third heating section sequentially connected in series in a longitudinal direction (a direction from the fixing portion 1213 to the insertion portion 1214), and widths of the first heating section, the second heating section, and the third heating section sequentially increase such that resistances of the first heating section, the second heating section, and the third heating section sequentially decrease to heat the baking aerosol-forming substrate 2 more uniformly. It will be appreciated that the heating arm is not limited to a three-segment resistance-decreasing configuration, as two or more segments may be used. Because the first heating part 1231 adopts a gradient resistor layout, the heating device 12 has the advantages of better energy utilization rate, better temperature field, large smoke amount during suction, better suction taste and the like.
The cold air enters the cigarette from bottom to top, and the heating device 12 and the lower part of the aerosol-forming substrate 2 are usually contacted with the low-temperature air first, so that the temperature difference is large, and the heat exchange efficiency is high. While the heating device 12 and the upper part of the aerosol-forming substrate 2 are usually in contact with the high temperature air heated by the lower part, the temperature difference is small, and the heat exchange efficiency is low. At this time, if the heating power of the upper and lower portions of the heating device 12 is equal, the temperature of the heating device 12 and the upper region of the aerosol-forming substrate 2 will always be higher than the temperature of the heating device 12 and the lower region of the aerosol-forming substrate 2 during use, which tends to cause excessive baking of a part of the tobacco shreds and insufficient baking of a part of the tobacco shreds. With the heating device 12 according to some embodiments of the present invention, this problem is advantageously solved, so that the temperature inside the aerosol-forming substrate 2 is more uniform during use.
The conductive line 123 may include first and second connection portions 1233 and 1234 having a lower resistance than the first and second heat generating portions 1231 and 1232 in some embodiments, and the first and second connection portions 1233 and 1234 may be made of one or more of gold, silver, and copper in some embodiments. The first connection portion 1233 may be formed on the conductive substrate 121 exposed at the notch 1220 in some embodiments and connected with the first ends of the first and second heat generating portions 1231 and 1232, thereby electrically connecting the first ends of the first and second heat generating portions 1231 and 1232 with the conductive substrate 121. The second connection portion 1234 is formed on the first insulating layer 122 and is connected to the second ends of the first and second heat generating portions 1231 and 1232. Here, the current may be transferred to the first ends of the first and second heat generating parts 1231 and 1232 via two parallel paths of the conductive substrate 121 and the first connection part 1233.
The conductive line 123 may include first and second leads 1235 and 1236 in some embodiments, and the first and second leads 1235 and 1236 may be soldered to the first and second connection portions 1233 and 1234, respectively. The first connection portion 1233 is preferably electrically connected to the positive electrode of the power source 13 via a first lead 1235, thereby electrically connecting the conductive substrate 121 to the positive electrode of the power source.
In some embodiments, the use of the conductive substrate 121 in electrical connection with one electrode of the power supply (preferably in electrical connection with the positive electrode of the power supply) has the following benefits: (1) The conductive substrate 121 has a high thermal conductivity and a more uniform temperature, and can ensure the overall atomization effect even when the temperature of the first heat generating part 1231 is low; (2) The electric connection performance is more stable, prevents to drop and reduces contact resistance.
The first protective layer 124 covers the outer surfaces of the first and second heat generating portions 1231 and 1232 to prevent the first and second heat generating portions 1231 and 1232 from directly contacting the aerosol-forming substrate 2 during use, thereby preventing the aerosol-forming substrate 2 from corroding the first and second heat generating portions 1231 and 1232. The first protective layer 124 may be made of glass or ceramic material in some embodiments.
The second insulating layer 125 may be formed on the second surface 1212 of the conductive substrate 121 in some embodiments to improve the insulating property of the side of the second surface 1212 of the conductive substrate 121. The second protective layer 126 is formed on the surface of the second insulating layer 125 to prevent corrosion of the second insulating layer 125 by the aerosol-forming substrate 2 during use or to prevent harmful substances in the second insulating layer 125 from entering into the aerosol-forming substrate 2. It will be appreciated that in some embodiments, the second insulating layer 125 and/or the second protective layer 126 may also be omitted if the conductive substrate 121 is made of a food-grade harmless and corrosion-resistant material.
It will be appreciated that in some embodiments, the heating device 12 may include two conductive traces 123, where the two conductive traces 123 are disposed on the first surface 1211 and the second surface 1212 of the conductive substrate 121, respectively, so that both sides of the conductive substrate 121 may be heated simultaneously, thereby further improving the heating efficiency.
