It should be understood that the terms "front", "back", "left", "right", "up", "down", "first", "second", etc. are used for convenience of describing the technical solutions of the present invention, and do not indicate that the devices or elements referred to must have special differences, and thus, the present invention cannot be construed as being limited. It will be understood that when an element is referred to as being "coupled" to another element, it can be directly coupled to the other element or intervening elements may also be present. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. 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.

Fig. 1 and 2 show a heated non-burning roasting apparatus 1 according to some embodiments of the present invention, the heated non-burning roasting apparatus 1 being used for heating and roasting a solid low-temperature roasted tobacco rod 2 detachably inserted therein to release a tobacco extract contained in tobacco in a non-burning state. As shown, rod 2 may be configured in a cylindrical manner. Accordingly, the top of the heating non-combustible roasting device 1 is provided with a jack 10 with a size matched with the cigarette 2, and a jack cover 15 is arranged beside the jack 10 to cover the jack 10 when not in use, so as to prevent foreign matters from entering the jack 10 and interfering with the use of the heating non-combustible roasting device 1.

Referring to fig. 3, the non-combustible heat-generating baking apparatus 1 may include a housing 11, and a heat-generating device 12, a battery 13 and a main board 14 disposed in the housing 11. The heating device 12 extends into the insertion hole 10 from the bottom of the insertion hole 10, so that when the cigarette 2 is inserted into the insertion hole 10, the heating device 12 can be longitudinally inserted into the cigarette 2 from the bottom end of the cigarette 2 to be closely contacted with the low-temperature baked tobacco in the cigarette 2. Therefore, when the heating device 12 is powered on to generate heat, the heat can be transferred to the tobacco, and the tobacco is heated to emit smoke. The battery 13 is electrically connected to the heat generating device 12, and the switch 15 is used to control the on/off of the two. The motherboard 14 is used for arranging related main control circuits.

As shown in fig. 4, the heat generating device 12 may have an elongated sheet shape in some embodiments, and includes an elongated sheet-shaped base 121, a heat generating body 122 arranged on the base 121 in a longitudinal direction, and two lead bonding parts 123 respectively connected to both ends of the heat generating body 122. The substrate 121 may be made of food grade stainless steel sheet in some embodiments, and may have a thickness of 0.4-0.7 mm. The heating element 122 may be a resistive heating film printed on the surface of the substrate 121 in some embodiments, and the lead bonding part 123 may be made of silver with very low resistance.

As shown in FIG. 5, base 121 may, in some embodiments, include a root 1211 for attachment, an insert portion 1213 for insertion into a cigarette 2, and a transition portion 1212 connecting root 1211 and insert portion 1213. The width W1 of the root 1211 is greater than the width W2 of the insertion portion 1213, and the root 1211 may be provided with a fixing hole 1214. The width W1 of the root 1211 may be 4-6mm in some embodiments and the length L1 may be 5-10 mm. The width W2 of insert 1213 may be 2-3.5mm in some embodiments and the length L2 may be 10-18 mm. Width W2 of insertion portion 1213 is in some embodiments less than or equal to 40% of the diameter of the tobacco rod, i.e. less than or equal to 40% of the bore diameter of receptacle 10.

The insertion portion 1213 may include a V-shaped tip 1215, and the angle α between the two sharp edges of the tip 1215 may be between 60 and 120 degrees to facilitate insertion into a cigarette 2. the heating element 122 is disposed on the insertion portion 1213 and the wire bond 123 is disposed on the root 1211. the length L of the entire base 121 may be between 18 and 31mm in some embodiments, and the thickness may be between 04 and 0.7 mm.

As shown in fig. 6, the heat generating body 122 may include two elongated heat generating arms 1221 arranged in parallel at intervals in the longitudinal direction of the insertion portion 1213 of the base 121 and V-shaped heat generating connecting portions 1222 connecting the two heat generating arms 1221 in series at the tip ends thereof, and the root portions of the two elongated heat generating arms 1221 are electrically connected to the two lead bonding portions 123, respectively. Each of the heating arms 1221 may include a first heating portion 1221a, a second heating portion 1221b, and a third heating portion 1221c sequentially connected in series along the longitudinal direction, and widths of the first heating portion 1221a, the second heating portion 1221b, and the third heating portion 1221c sequentially increase, so that resistances of the first heating portion 1221a, the second heating portion 1221b, and the third heating portion 1221c sequentially increase, thereby heating the roast cigarette 2 more uniformly. It is to be understood that the heater 1221 is not limited to the three-stage decreasing resistance structure, and two or more stages may be used.

Because the heating element 122 adopts the gradient resistor layout, the heating device 12 has the advantages of better energy utilization rate, better temperature field, large smoke amount during smoking, better smoking taste and the like.

The cold air enters the cigarette from bottom to top, and the insertion part 1213 and the lower part of the cigarette are generally contacted with the low-temperature air firstly, so that the temperature difference is large, and the heat exchange efficiency is high. The insertion part 1213 and the upper part of the cigarette are usually contacted with the high temperature air heated by the lower part, so the temperature difference is small and the heat exchange efficiency is low. At this time, if the heating power of the upper part and the lower part of the insertion part is equal, the temperature of the insertion part 1213 and the upper region of the cigarette will be always higher than the temperature of the insertion part 1213 and the lower region of the cigarette during the use process, which easily results in over-baking part of the cut tobacco and under-baking part of the cut tobacco. By adopting the heating device 12 in some embodiments of the invention, the problem can be solved better, so that the temperature inside the cigarette can be more balanced in the using process.

As shown in fig. 7, in some embodiments, since the base 121 is made of a metal material, before the heating element 122 is disposed, an insulating layer 124 is formed on the surface, and then the heating element 122 is disposed on the insulating layer 122. The welding part 123 is provided in a form that one end thereof is lapped on the heating element 122. In order to prevent the heating element 122 and the welding portion 123 from being corroded by tobacco or oxidized by air, a protective layer 125 is coated on the entire outer surfaces of the base 121, the heating element 122, the welding portion 123, and the insulating layer 124.

It is to be understood that the foregoing examples, while indicating the preferred embodiments of the invention, are given by way of illustration and description, and are not to be construed as limiting the scope of the invention; it should be noted that, for those skilled in the art, the above technical features can be freely combined, and several changes and modifications can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention; therefore, all equivalent changes and modifications made within the scope of the claims of the present invention should be covered by the claims of the present invention.
