Description

Technical Field

[0001] The present invention belongs to the field of tobacco equipment, and particularly relates to an electromagnetic heating smoking device and its use. Background Art

[0002] Traditional cigarettes release nicotine, flavor components, etc. in tobacco through combustion to meet the needs of consumers. Heat-not-burn cigarettes heat tobacco products to the atomization temperature by an external heat source without combustion to achieve the effect of generating smoke, and the heating temperature is lower than the combustion temperature of tobacco, which can significantly reduce a large amount of harmful substances generated by cigarette combustion and reduce the harm of second-hand smoke to non-smoking people.

[0003] Heat-not-burn cigarettes can be divided into heating forms such as electric heating and carbon heating according to the nature of the heat source. Among them, the electric heating method has advantages such as simple and convenient temperature control and easy production, so it is the heating form commonly used in the heat-not-burn cigarette industry at present. Electric heating type heat-not-burn cigarettes can be further divided into a central heating type and a circumferential heating type according to the contact form between the heating element and the tobacco substance. Both of these two types can be divided into an electromagnetic heating type and a resistance heating type according to the heat energy source of the heating element; among them, the resistive central heating type is the main heating combination form in the industry at present.

[0004] With the gradual maturity of electromagnetic heating technology, the electromagnetic heating type has gradually been adopted by major tobacco companies. The working principle of the electromagnetic heating type is to heat ferromagnetic substances through the eddy current heating principle and then conduct heat to the smoking material in the heat-not-burn cigarette rod in a contact manner. At present, most in the industry adopt the method of placing ferromagnetic substances inside the heat-not-burn cigarette rod, and when sucking, the cigarette rod is inserted into its matching smoking device for heating. At present, there are also cases in the industry where the ferromagnetic substances used for heating are set in the smoking device rather than in the cigarette rod. This smoking device also needs to be used together with the matching heat-not-burn cigarette rod. After the cigarette rod is inserted, it contacts the ferromagnetic substances to conduct heat for heating; however, an obvious disadvantage of this smoking device is that the inner wall of the heating cavity is prone to fouling, the cleaning is cumbersome, and the experience is poor. In addition, the existing smoking devices are only used with their matching cigarette rods, that is, the smoking devices are either provided with ferromagnetic substances for heating or are non-ferromagnetic and are only used as smoking devices for matching heat-not-burn cigarette rods with ferromagnetic substances inside; at present, there is no smoking device that can be used for both heat-not-burn cigarette rods with ferromagnetic substances inside and traditional heat-not-burn cigarette rods without ferromagnetic substances inside.

[0005] The present invention is proposed to solve the above problems. Summary of the Invention

[0006] The present invention discloses an electromagnetic heating smoking device, which can be used for both heated tobacco products with an internal ferromagnetic material and heated tobacco products without an internal ferromagnetic material.

[0007] The technical solution of the present invention is as follows:

[0008] In a first aspect, the present invention discloses an electromagnetic heating smoking device, which comprises:

[0009] A heating element 1;

[0010] A heating element base 2 for fixing the heating element 1; the heating element base 2 and the heating element 1 can move up and down together;

[0011] Sealing sheets 3, located at the bottom of the cigarette receiving cavity of the electromagnetic heating smoking device, and there are multiple sealing sheets 3;

[0012] Sealing sheet linkages 4, connected to the lower surface of the sealing sheets 3, and the number of the sealing sheet linkages 4 is the same as the number of the sealing sheets 3; the sealing sheet linkages 4 are used to control the opening and closing of the multiple sealing sheets 3.

[0013] Preferably, the upper part of the heating element 1 has a pointed end, which is sword-shaped or rod-shaped with a pointed end.

[0014] Preferably, there are two sealing sheets 3.

[0015] Preferably, the outer wall of the electromagnetic heating smoking device has a telescopic switch 5.

[0016] In a second aspect, the present invention discloses the use of the electromagnetic heating smoking device for heated tobacco products with an internal ferromagnetic material.

[0017] Preferably, the steps of using the electromagnetic heating smoking device for sucking heated tobacco products with an internal ferromagnetic material are as follows: turn on the telescopic switch 5, move the heating element base 2 and the heating element 1 downward together so that the heating element 1 completely leaves the cigarette receiving cavity, and the sealing sheets 3 are closed; insert the heated tobacco product with an internal ferromagnetic material into the cigarette receiving cavity, turn on the heating power supply to heat the cigarette for the smoker to suck.

[0018] In a second aspect, the present invention further discloses the use of the electromagnetic heating smoking device for heated tobacco products without an internal ferromagnetic material.

[0019] Preferably, the steps of using the electromagnetic heating smoking device for sucking a heat-not-burn cigarette stick without an internal ferromagnetic substance are as follows: Turn on the telescopic switch 5, move the heating element base 2 and the heating element 1 upward together, so that the heating element 1 enters the cigarette stick accommodating cavity, and the sealing piece 3 is closed; Insert the heat-not-burn cigarette stick without an internal ferromagnetic substance into the cigarette stick accommodating cavity, insert the heating element 1 into the cigarette stick, turn on the heating power supply to heat the cigarette stick for the smoker to suck.

[0020] Advantages of the present invention:

[0021] Based on the electromagnetic heating smoking device in the prior art, the electromagnetic heating smoking device of the present invention is provided with a heating element, which can be used or not used to match different types of heat-not-burn cigarette sticks on the current market. When the cigarette stick has an internal ferromagnetic substance, the heating element does not need to be used, and the heating element 1 completely leaves the cigarette stick accommodating cavity, and the sealing piece 3 is closed to form a sealed cigarette stick accommodating cavity, and there is no scale in the cigarette stick accommodating cavity after the cigarette stick is smoked. When the cigarette stick has no internal ferromagnetic substance, the heating element needs to be used, and the heating element 1 extends into the cigarette stick accommodating cavity. At this time, the sealing piece 3 is also closed to form a sealed cigarette stick accommodating cavity. The heating element 1 is inserted into the cigarette stick. After the cigarette stick is smoked and pulled out, there is no scale in the cigarette stick accommodating cavity. Therefore, the electromagnetic heating smoking device of the present invention can be used for both heat-not-burn cigarette sticks with internal ferromagnetic substances and heat-not-burn cigarette sticks without internal ferromagnetic substances.
