Description

FIELD

[0001] The present disclosure relates to baking devices, and more specifically, to a heat-not-burn baking device and a heating component thereof.

BACKGROUND

[0002] As a substitute for a cigarette, an e-cigarette has attracted more and more attention and favor because of its advantages of safety, convenience, health and environmental protection. The heat-not-burn e-cigarette works at a relatively low temperature, thus the components of the cigarette are heated and atomized at a lower temperature. The heating method is usually tubular peripheral heating or central embedded heating. The former means that a heating tube surrounds the outside of the cigarette, and the latter means that a heating sheet or a heating rod is inserted into the cigarette. Wherein, the heating sheet is widely used because of its simple manufacture and convenient use. However, the existing heating sheet is easy to cause problems such as poor electrical contact and unstable current when the conductive trace works since the conductive trace is formed on the surface of the insulating ceramic through screen printing or coating.

DETAILED DESCRIPTION

[0030] In order to more clearly illustrate the present disclosure, the technical solutions in the embodiments of the present disclosure will be described in even greater detail below with reference to the accompanying drawings.

[0031] Fig. 1 and Fig. 2 show a heat-not-burn baking device 1 in some embodiments of the present disclosure. The heat-not-burn baking device 1 is used to heat and bake an aerosol producing substrate 2 detachably inserted therein, so as to release the aerosol extract in the aerosol producing substrate 2 in a non combustion state. As shown in the figures, the aerosol producing substrate 2 may be a cigarette in a cylindrical shape. Accordingly, the top of the heat-not-burn baking device 1 is provided with an insertion hole 10 whose size is adapted to that of the aerosol producing substrate 2. An insertion-hole cover 15 may be provided beside the insertion hole 10 to cover the insertion hole 10 when not in use, so as to prevent foreign matters from entering the insertion hole 10 to hinder the use of the heat-not-burn baking device 1.

[0032] Referring to Fig. 3, in some embodiments, the heat-not-burn baking device 1 may include a shell 11, a heating component 12, a power supply 13, and a circuit board 14 that are disposed in the shell 11. The heating component 12 extends into the insertion hole 10 from the bottom of the insertion hole 10, so that when the aerosol producing substrate 2 is inserted into the insertion hole 10, the heating component 12 may be inserted into the aerosol producing substrate 2 along the longitudinal direction from the bottom of the aerosol producing substrate 2, to be in close contact with the low-temperature baking aerosol producing substrate 2 in the aerosol producing substrate 2. In this way, when the heating component 12 is powered on for heating, the heat can be transferred to the aerosol producing substrate 2, so that the aerosol producing substrate 2 can be heated to generate smoke. The power supply 13 is electrically connected to the heating component 12, and the on/off between the two may be controlled by a switch. The circuit board 14 is configured for arranging the relevant control circuits.

[0033] As shown in Figs. 4 to 6, the heating component 12 in some embodiments may 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 that are combined with the conductive substrate 121. In some embodiments, the conductive trace 123 may include a first end and a second end configured for electrically connecting the positive electrode and the negative electrode of the power supply 13, respectively. Wherein, the first end is electrically connected to the conductive substrate 121, and the second end is electrically insulated from the conductive substrate 121, so that the current can enter the conductive trace 123 from the first end through the conductive substrate 121, and then flow out of the conductive trace 123 from the second end.

[0034] In some embodiments, the conductive substrate 121 may be made of conductive material such as metal such as stainless steel, or conductive ceramics, with a thickness of 0.4 mm to 0.7 mm. As shown in Fig.7, in some embodiments, the conductive substrate 121 may be in a longitudinal sheet shape, and may include a flat first surface 1211 and a flat second surface 1212 opposite to the first surface 1211. In some embodiments, the conductive substrate 121 may include a fixing portion 1213 for fixing to the shell 11 and an insertion portion 1214 connected to the fixing portion 1213. The insertion portion 1214 is configured for inserting into the aerosol producing substrate 2, and may include a V-shaped tip 1215 to facilitate the insertion into the aerosol producing substrate 2. Two opposite side edges of the insertion portion 1214 and two adjacent edges of the tip 1215 may be sharpened to further facilitate the insertion into the aerosol producing substrate 2.

[0035] In some embodiments, the first insulating layer 122 may be made of one or more materials of glass, ceramics and polyimide, and is disposed on the first surface 1211 of the conductive substrate 121, and may be provided with a notch 1220 at a corner of its root, so that the conductive substrate 121 is exposed outside the first insulating layer 122 at the notch 1220.

[0036] In some embodiments, the conductive trace 123 may include a first heating portion 1231 and a second heating portion 1232 with large resistance temperature characteristics. The first heating portion 1231 and the second heating portion 1232 may be formed on a surface of the first insulating layer 122 by screen printing or electroplating to be electrically insulated from the conductive substrate 121. The first heating portion 1231 and the second heating portion 1232 may be U-shaped in some embodiments, and the second heating portion 1232 is located inside the first heating portion 1231. The first end and the second end of the first heating portion 1231 are respectively connected to the first end and the second end of the second heating portion 1232, so that the first heating portion 1231 and the second heating portion 1232 are connected in parallel. In some embodiments, the first heating portion 1231 and the second heating portion 1232 may be made of one or more materials of silver, platinum, copper, nickel and palladium. In some embodiments, the first heating portion 1231 or the second heating portion 1232 may be used for temperature measurement to better monitor the heating temperature.

[0037] In some embodiments, the first heating portion 1231 may include two lengthwise heating arms that are arranged in parallel and spaced apart along the length direction of the conductive substrate 121 and a V-shaped heating part connecting the two heating arms in series at the top. The roots of the two lengthwise heating arms form the first end and the second end of the first heating portion 1231, respectively. Each heating arm may include a first heating section, a second heating section and a third heating section that are sequentially connected in series in the longitudinal direction (from the fixing portion 1213 to the insertion portion 1214). The widths of the first heating section, the second heating section and the third heating section increases in sequence, so that the resistances of the first heating section, the second heating section and the third heating section decreases in sequence, so as to heat and bake the aerosol producing substrate 2 more evenly. It may be understood that the heating arm is not limited to the three-section resistance decreasing structure, and may alternatively be two or more sections. Since the first heating portion 1231 adopts a gradient resistance layout, the heating component 12 has a better energy utilization, a better temperature field, and has advantages of a large smoke volume and a better suction taste and the like.

[0038] The cold air enters the cigarette from the bottom to the top, and the lower portions of the heating component 12 and the aerosol producing substrate 2 generally contacts the cold air first, thus having large temperature difference and high heat exchange efficiency. The upper portions of the heating component 12 and the aerosol producing substrate 2 generally contacts with the high-temperature air heated by the lower portions, thus having small temperature difference and low heat transfer efficiency. If the heating powers of the upper portion and the lower portion of the heating component 12 are equal, the temperatures of the upper portions of the heating component 12 and the aerosol producing substrate 2 will always be higher than the temperatures of the lower portions of the heating component 12 and the aerosol producing substrate 2, which is likely to lead to excessive baking of some cut tobacco and insufficient baking of another some cut tobacco. By implementing the heating component 12 in some embodiments of the present disclosure, the above problem can be better solved, so that the temperatures in the aerosol producing substrate 2 may be more balanced during use.

[0039] In some embodiments, the conductive trace 123 may include a first connecting portion 1233 and a second connecting portion 1234 with a lower resistance than the first heating portion 1231 and the second heating portion 1232. The first connecting portion 1233 and the second connecting portion 1234 may be made of one or more of gold, silver and copper in some embodiments. In some embodiments, the first connecting portion 1233 may be formed on the conductive substrate 121 and exposed at the notch 1220, and connected with the first ends of the first heating portion 1231 and the second heating portion 1232, so as to electrically connect the first ends of the first heating portion 1231 and the second heating portion 1232 with the conductive substrate 121. The second connecting portion 1234 is formed on the first insulating layer 122 and connected with the second ends of the first heating portion 1231 and the second heating portion 1232. In this way, the current may be transmitted to the first ends of the first heating portion 1231 and the second heating portion 1232 through two parallel paths of the conductive substrate 121 and the first connecting portion 1233.

[0040] In some embodiments, the conductive trace 123 may include a first lead 1235 and a second lead 1236, which may be welded to the first connecting portion 1233 and the second connecting portion 1234, respectively. The first connecting portion 1233 is preferably electrically connected to the positive electrode of the power supply 13 via the first lead 1235, thereby electrically connecting the conductive substrate 121 to the positive electrode of the power supply.

[0041] In some embodiments, by utilizing the conductive substrate 121 electrically connected to one electrode of the power supply (preferably to the positive electrode of the power supply) provides the following beneficial effects: (1) the conductive substrate 121 has a high thermal conductivity and a more uniform temperature, and the overall atomization effect may be guaranteed when the temperature of the first heating portion 1231 is relatively low; (2) the electrical connection performance is more stable, to prevent falling off and reduce the contact resistance.

[0042] The first protective layer 124 covers the outer surfaces of the first heating portion 1231 and the second heating portion 1232 to prevent the first heating portion 1231 and the second heating portion 1232 from directly contacting the aerosol producing substrate 2 during use, thereby preventing the first heating portion 1231 and the second heating portion 1232 from being corroded by the aerosol producing substrate 2. The first protective layer 124 may be made of glass or ceramic material in some embodiments.

[0043] In some embodiments, the second insulating layer 125 may be formed on the second surface 1212 of the conductive substrate 121 to improve the insulation performance of the side of the conductive substrate 121 where the second surface 1212 is located. The second protective layer 126 is formed on a surface of the second insulating layer 125 to prevent the corrosion of the second insulating layer 125 by the aerosol producing substrate 2 during use, or to prevent harmful substances in the second insulating layer 125 from entering the aerosol producing substrate 2. It can be understood that in some embodiments, if the conductive substrate 121 is made of a food grade harmless and corrosion-resistant material, the second insulating layer 125 and/or the second protective layer 126 may be omitted.

[0044] It may be understood that in some embodiments, the heating component 12 may include two conductive traces 123, which are respectively disposed on the first surface 1211 and the second surface 1212 of the conductive substrate 121, so that the two sides of the conductive substrate 121 may be heated at the same time, thereby further improving the heating efficiency.

[0045] Figs. 8 to 10 show a heating component 12a in some embodiments of the present disclosure, and the heating component 12a may be used as an alternative to the above-mentioned heating component 12. In some embodiments, the heating component 12a may include a conductive substrate 121a, and a first insulating layer 122a, a conductive trace 123a, a first protective layer 124a, a second insulating layer 125a and a second protective layer 126a that are combined with the conductive substrate 121a. In some embodiments, the conductive trace 123a may include a first end and a second end configured for electrically connecting the positive and negative electrodes of the power supply 13, respectively. Wherein, the first end is electrically connected to the conductive substrate 121a, and the second end is electrically insulated from the conductive substrate 121a, so that the current may flow to the conductive trace 123a from the first end via the conductive substrate 121a, and then flow out of the conductive trace 123a from the second end.

[0046] In some embodiments, the conductive substrate 121a may be in an elongated sheet shape, which may include a flat first surface 1211a and a flat second surface 1212a opposite to the first surface 1211a. The first insulating layer 122a is formed on the first surface 1211a of the conductive substrate 121a, and may be provided with a notch 1220a at a corner of its root, so that the conductive substrate 121a is exposed out of the first insulating layer 122a there.

[0047] In some embodiments, the conductive trace 123a may include a first heating portion 1231a and a second heating portion 1232a with high resistance. The first heating portion 1231a and the second heating portion 1232a may be formed on a surface of the first insulating layer 122a by screen printing or electroplating to be electrically insulated from the conductive substrate 121a. The first heating portion 1231a and the second heating portion 1232a may be U-shaped in some embodiments, and the second heating portion 1232a is located on the inner side of the first heating portion 1231a. The first end and the second end of the first heating portion 1231a are respectively connected with the first end and the second end of the second heating portion 1232a, so that the first heating portion 1231a and the second heating portion 1232a are connected in parallel. In some embodiments, the first heating portion 1231a and the second heating portion 1232a may be made of one or more materials of silver, platinum, copper, nickel and palladium.

[0048] In some embodiments, the conductive trace 123a may include a first connecting portion 1233a and a second connecting portion 1234a having a smaller resistance than the first heating portion 1231a and the second heating portion 1232a. In some embodiments, the first connecting portion 1233a and the second connecting portion 1234a may be made of the same material as the first heating portion 1231a and the second heating portion 1232a, and may be integrally formed with the first heating portion 1231a and the second heating portion 1232a. In some embodiments, the first connecting portion 1233a may be formed on the conductive substrate 121a and exposed at the notch 1220a, and connected with the first ends of the first heating portion 1231a and the second heating portion 1232a, so as to electrically connect the first ends of the first heating portion 1231a and the second heating portion 1232a with the conductive substrate 121a. The second connecting portion 1234a is formed on the first insulating layer 122a and connected with the second ends of the first heating portion 1231a and the second heating portion 1232a. Thereby, the current can be transmitted to the first ends of the first heating portion 123 1a and the second heating portion 1232a through two parallel paths of the conductive substrate 121a and the first connecting portion 1233a.

[0049] In some embodiments, the conductive trace 123a may include a first lead 1235a and a second lead 1236a, which may be welded to the first connecting portion 1233a and the second connecting portion 1234a, respectively. Preferably, the first lead 1235a is electrically connected to the positive electrode of the power supply.

[0050] The first protective layer 124a covers the outer surfaces of the first heating portion 1231a and the second heating portion 1232a to prevent the first heating portion 1231a and the second heating portion 1232a from directly contacting the aerosol producing substrate 2 during use, thereby preventing the first heating portion 1231a and the second heating portion 1232a from being corroded by the aerosol producing substrate 2. The first protective layer 124a may be made of glass or ceramic material in some embodiments.

[0051] In some embodiments, the second insulating layer 125a may be formed on the second surface 1212a of the conductive substrate 121a to improve the insulation performance of the side of the conductive substrate 121a where the second surface 1212a is located. The second protective layer 126a is formed on the surface of the second insulating layer 125a to prevent the corrosion of the second insulating layer 125a by the aerosol producing substrate 2 during use, or to prevent harmful substances in the second insulating layer 125a from entering the aerosol producing substrate 2.

[0052] Figs. 11 to 13 show a heating component 12b in some embodiments of the present disclosure, and the heating component 12b may be used as an alternative to the above-mentioned heating component 12. In some embodiments, the heating component 12b may include a conductive substrate 121b, and a first insulating layer 122b, a conductive trace 123b, a first protective layer 124b, a second insulating layer 125b, and a second protective layer 126b that are combined with the conductive substrate 121b. In some embodiments, the conductive trace 123b may include a first end and a second end configured for electrically connecting the positive and negative electrodes of the power supply 13, respectively. Wherein, the first end is electrically connected to the conductive substrate 121b, and the second end is electrically insulated from the conductive substrate 121b, so that the current may flow to the conductive trace 123b from the first end through the conductive substrate 121b, and then flow out of the conductive trace 123b from the second end.

[0053] In some embodiments, the conductive substrate 121b may be in an elongated sheet shape, which may include a flat first surface 1211b and a flat second surface 1212b opposite to the first surface 1211b. The first insulating layer 122b is formed on the first surface 1211b of the conductive substrate 121b, and may be provided with a notch 1220b at a corner of its root, so that the conductive substrate 121b is exposed outside the first insulating layer 122b there. A through hole 1221b is further provided on the first insulating layer 122b adjacent to the notch 1220b, where the conductive substrate 121b is also exposed outside the first insulating layer 122b.

[0054] The conductive trace 123b may include a first heating portion 1231b and a second heating portion 1232b with large resistance in some embodiments. The first heating portion 1231b and the second heating portion 1232b may be formed on the surface of the first insulating layer 122b by silk screen printing or electroplating to be electrically insulated from the conductive substrate 121b. In some embodiments, the first heating portion 1231b and the second heating portion 1232b may be U-shaped, and the second heating portion 1232b is located on the inner side of the first heating portion 1231b. The first end and the second end of the first heating portion 1231b are respectively connected with the first end and the second end of the second heating portion 1232b, so that the first heating portion 1231b and the second heating portion 1232b are connected in parallel. The first heating portion 1231b and the second heating portion 1232b may be made of one or more of silver, platinum, copper, nickel and palladium in some embodiments. The connection between the first end of the first heating portion 1231b and the first end of the second heating portion 1232b further corresponds to the through hole 1221b of the first insulating layer 122b, so that the connection between the first end of the first heating portion 1231b and the first end of the second heating portion 1232b is combined with the conductive substrate 121b. In this way, the current can be transmitted to the first ends of the first heating portion 1231b and the second heating portion 1232b through two parallel paths of the conductive substrate 121b and the first connecting portion 1233b.
