[0004] The technical solution provided by the present invention is as follows: A multi-sensor electromagnetic induction heating cigarette comprises a tobacco segment and a mouthpiece segment. The tobacco segment is provided with a tobacco portion and two or more metal foils located in the tobacco portion. The metal foils are made of magnetic materials.

[0005] Preferably, the metal foil is in a flattened state within the tobacco portion.

[0006] Preferably, two or more of the metal foils are arranged in parallel at a certain distance or at a certain angle at a certain distance.

[0007] Preferably, two or more of the metal foils are arranged around the center line of the tobacco segment.

[0008] Preferably, the metal foil is in a curled state within the tobacco portion.

[0009] Preferably, the two or more metal foils are not in contact with each other.

[0010] Preferably, the thickness of the metal foil is 0.0001 mm to 0.5 mm.

[0011] Preferably, the width of the metal foil is not less than 1 / 5 of the inner diameter of the tobacco segment and not more than 2 / 3 of the inner diameter of the tobacco segment.

[0012] Preferably, the length direction of the metal foil is consistent with the length direction of the tobacco segment, and the actual length of the metal foil in the tobacco portion is not less than 1 / 2 of the length of the tobacco segment and not greater than the length of the tobacco segment.

[0013] Preferably, the tobacco portion includes one or more combinations of a plurality of atomizing sheets, atomizing shreds, shredded tobacco, and tobacco particles.

[0014] The present invention has the following advantages over the prior art: The multi-sensor electromagnetic induction heating cigarette of the present invention has a tobacco section and two or more metal foils located in the tobacco section. Instead of using a single sensor, two or more sensors are used, which can better meet the requirements of electromagnetic heating, thereby realizing electromagnetic induction heating to heat the cigarette, greatly improving the heating efficiency, shortening the time from heating to atomization of tobacco, and enhancing the satisfaction of consumers.

[0018] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention are clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0019] Embodiment 1: like Figure 1 , 2 As shown, an embodiment of the present invention provides a multi-sensor electromagnetic induction heating cigarette, including a tobacco segment 1 and a mouthpiece segment 2 (the mouthpiece segment 2 is composed of a hollow mouthpiece, a cooling mouthpiece and a mouthpiece. Of course, in other embodiments, the mouthpiece segment 2 of this type of cigarette can also be composed of a single or multiple mouthpieces). A tobacco section 11 and two metal foils 12 located in the tobacco section 11 are provided in the tobacco segment 1. The metal foils 12 are made of magnetic materials, and can specifically be composed of ferromagnetic materials such as iron, iron alloy, stainless steel or ferrite.

[0020] In this embodiment, the metal foil 12 is flattened in the tobacco portion 11. The two metal foils 12 are arranged in parallel at a certain distance, and the electromagnetically heated cigarette can be heated more quickly, and the atomization efficiency of the cigarette is higher, which better meets the needs of consumers.

[0021] In this embodiment, the thickness of the metal foil 12 is 0.0001 mm to 0.5 mm. The width of the metal foil 12 is not less than 1 / 5 of the inner diameter of the tobacco segment 1 and not more than 2 / 3 of the inner diameter of the tobacco segment 1, so that the tobacco portion 11 can wrap the metal foil 12 therein. The length direction of the metal foil 12 is consistent with the length direction of the tobacco segment 1, and the actual length of the metal foil 12 in the tobacco portion 11 is not less than 1 / 2 of the length of the tobacco segment 1 and not more than the length of the tobacco segment 1, so that the function of the metal foil 12 can be exerted.

[0022] In this embodiment, the tobacco portion 11 includes a combination of atomized shreds and tobacco shreds. The atomization temperature of the tobacco portion 11 is maintained at 150° C. to 400° C., preferably 200° C. to 380° C., which can achieve the effect of quickly generating smoke.

[0023] Embodiment 2: like Figure 3 As shown, the difference between this embodiment and embodiment 1 is that the number of metal foils 12 is three, and the three metal foils 12 are arranged at a certain distance and a certain angle (60° in this embodiment). The three metal foils 12 are arranged around the center line of the tobacco segment, and the electromagnetically heated cigarette can be heated more quickly, and the atomization efficiency of the cigarette is higher, which better meets the needs of consumers. The tobacco part 11 includes a combination of a plurality of atomizing sheets, atomizing shreds, tobacco shreds, and tobacco particles. The rest is the same as embodiment 1.

[0024] Embodiment 3: like Figure 4As shown, the difference between this embodiment and embodiment 1 is that the two metal foils 12 are curled in the tobacco portion, and can be curled into a wavy structure, or into an arc, semicircle, ellipse, circle, etc. The two metal foils 11 do not contact each other. The rest is the same as embodiment 1.

[0025] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
