[0002] A type of tobacco (cigarette) currently in use includes tobacco shreds and wrapping paper. The tobacco shreds are rolled into a cylindrical shape, a filter is provided at one end of the tobacco shreds, and the outer periphery of the tobacco shreds is wrapped with wrapping paper. When in use, the tobacco is ignited, and the tobacco shreds burn in an open flame state, and the aroma after burning is inhaled through the filter. This method of ignition with an open flame seems simple, but it is actually not advisable, because when the tobacco shreds burn, chemical changes occur, and the temperature is above 800 degrees Celsius. During the burning process of cigarettes, more than 5,000 chemical substances are produced, of which more than 80 are carcinogenic chemicals. The smoke produced is quite harmful to non-smoking people.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 this field without creative work are within the scope of protection of the present invention.

[0033] like Figure 1-Figure 6 The embodiment of the present invention provides an electromagnetic induction tobacco, which includes: a tobacco shred 1; a metal layer 2, which is sleeved on the periphery of the tobacco shred 1; and a wrapping paper 3, which is wrapped on the periphery of the metal tube.

[0034] A filter is arranged at one end of the tobacco 1, both ends of the metal layer 2 are open, the metal layer 2 is cylindrical, the filter is located at one end of the metal layer 2, the metal layer 2 can be a metal sheet, which is then bent into a cylindrical shape, or can be tin foil, etc.

[0035] The metal layer 2 of the present invention has two configuration methods, specifically, the upper end of the metal layer 2 is open, a bottom cover 22 is provided at the lower part of the metal layer 2, a latching protrusion 23 is provided around the bottom cover 22, and a slide groove 21 is provided along the up and down directions of the metal layer 2, the latching protrusion 23 is installed in the slide groove 21 and can slide up and down in the slide groove 21.

[0036] Another design of the metal layer 2 is that the upper end of the metal layer 2 is open, a bottom cover 22 is provided at the lower part of the metal layer 2, a slide groove 21 is provided around the bottom cover 22, and a latching protrusion 23 is provided on the inner wall of the metal layer 2 along the up and down directions. The latching protrusion 23 is installed in the slide groove 21 and can slide up and down in the slide groove 21.

[0037] The bottom cover 22 is provided with an air inlet 24, which allows outside air to enter, so that the vaporized aroma can be taken away in time when smoking. Of course, the design of the metal layer 2 can also be a mixture of the above two methods, that is, the metal layer 2 can be provided with a slide groove 21 and a cam 23, and the bottom cover 22 can be provided with a mixture of the cam 23 and the slide groove 21, and the slide groove 21 can correspond to the cam 23, so as to meet the sliding requirements in the metal layer 2 in the up and down directions.

[0038] A method for making electromagnetic induction tobacco, comprising the following steps:

[0039] a. Installing the tobacco 1 on the metal layer 2;

[0040] b. Wrap the wrapping paper 3 around the periphery of the metal layer 2.

[0041] Furthermore, a bottom cover 22 is provided at the lower part of the metal layer 2. Before step a, the bottom cover 22 needs to be placed at the bottom of the metal layer 2 to expose the opening at the upper part of the metal layer 2, and then the tobacco 1 is installed in the metal layer 2. After the tobacco 1 is installed in the metal layer 2, the tobacco 1 is squeezed downward.

[0042] Furthermore, after step a, a filter tip is installed at the opening of the metal layer 2, and then the metal layer 2 and the filter tip are covered with a wrapping paper 3.

[0043] The present invention places tobacco in a changing magnetic field, generates eddy currents in the metal layer 2 through electromagnetic induction heating, and the metal layer 2 generates heat, which is transferred to the tobacco 1 to evaporate the aroma in the tobacco 1. Low-temperature heating is adopted without the need for open flame ignition, and the generation of various harmful substances under high-temperature conditions is effectively avoided, thereby greatly improving the taste, healthiness and cleanliness of the tobacco. The electromagnetic induction heating speed is fast, and the effect of immediate use is achieved.

[0044] The present invention also provides a method for making electromagnetic induction tobacco, wherein tobacco 1 is installed on a metal layer 2, and the specific operation is as follows: first, a bottom cover 22 is installed on the metal layer 2, or the metal layer 2 already has a bottom cover 22, and the bottom cover 22 is placed on the bottom of the metal layer 2. Since the bottom cover 22 can slide in the up and down directions of the metal layer 2, the metal layer 2 is only allowed to be placed in the up and down directions, and then the bottom cover 22 is vibrated or pushed to make the bottom cover 22 located at the bottom of the metal layer 2, and then the tobacco 1 is loaded from the open end (upper end) of the metal layer 2, and the tobacco 1 is squeezed to stabilize the tobacco 1 in the metal layer 2 to prevent the tobacco 1 from loosening and falling off. In addition, by squeezing the tobacco 1, the bottom cover 22 can be squeezed to the bottom end of the metal layer 2 again. For metal layers 2 of the same size, the present invention can be used to make the tobacco 1 stable in the metal layer 2, thereby preventing the tobacco 1 from loosening and falling off. The method of design can load the maximum amount of tobacco 1, because the bottom cover 22 is squeezed at least twice here. In addition, the design of the slide groove 21 in the metal layer 2 is not only for the card protrusion 23 to slide in the card groove. In the subsequent process of heating the tobacco, the outside air can also enter through the card groove, so as to maximize the air entry and improve the taste of the tobacco. Even without the wrapping paper 3, the metal layer 2 of the present design can also be used alone. After the tobacco 1 is loaded, electromagnetic induction heating can be performed. The design is ingenious. After the tobacco uses the outer wall, the metal layer 2 is taken out, and the evaporated tobacco 1 can be pushed out by pushing the bottom cover 22, and then it can be cleaned. The bottom cover 22 slides in the metal layer 2, which can drive the cleaning process, and then the tobacco 1 is repeatedly loaded and reused to improve the utilization rate.

[0045] The present invention also provides a method for detecting tobacco by electromagnetic induction, which comprises the following steps:

[0046] (1) An electromagnetic induction generator 4 is provided, the electromagnetic induction generator 4 comprising a main body, a power supply, and a circuit board. An induction coil 41 and a ceramic heat receiving cavity 42 are sequentially installed in the main body from the outside to the inside, the induction coil 41 surrounds the ceramic heat receiving cavity 42, the ceramic heat receiving cavity 42 is provided with a temperature sensor 43 and a detection element 44, and the detection element 44 and the temperature sensor 43 are connected to the circuit board;

[0047] (2) Turn on the power supply, place the electromagnetic induction tobacco in the ceramic heat receiving chamber 42, and the detection member 44 detects the entry of tobacco. If the entry of tobacco is detected, a signal is sent to the circuit board. After receiving the signal, the circuit board immediately sends an instruction to start the induction coil 41 to work. The induction coil 41 generates a changing magnetic field, and the metal layer starts to generate heat;

[0048] (3) After the metal layer generates heat, the temperature sensor 43 constantly detects the temperature of the metal layer and feeds back the detected temperature to the circuit board. The circuit board adjusts the working power of the metal layer according to the received signal.

[0049] The detection components 44 are two metal probes arranged in the ceramic heat containing cavity 42. The detection components 44 detect the impedance of the metal layer. If the impedance is within a predetermined range, the circuit board is notified to start working. Otherwise, the circuit board does not start working. The detection is simple, safe, reliable, convenient and practical.
