[0033] FIG. 1 is a diagram showing an example of an aerosol generating device with a cigarette inserted therein.

[0034] Referring to FIG. 1, the aerosol generating device 10000 includes a battery 11000 and a control unit 1 2000, coil 14000, and susceptor 15000. Also, the aerosol generating device A cigarette 20000 can be inserted into the internal space of the device 10000.

[0035] The aerosol generating device 10000 shown in FIG. 1 includes some components related to this embodiment. Therefore, other components than those shown in FIG. The present embodiment relates to a technical field that may further include the above-mentioned Any person with ordinary knowledge can understand this.

[0036] In FIG. 1, a battery 11000, a control unit 12000, and a susceptor 15000 are arranged in a row. The aerosol generating device is shown in FIG. The battery 11000, the control unit 12000, and the susceptor 13000 are designed according to the design of the device 10000. The arrangement of the data 15000 may be changed.

[0037] When the cigarette 20000 is inserted into the aerosol generating device 10000, the aerosol generating device The forming apparatus 10000 can be heated by induction heating. The aerosol generating material in the chamber 20000 is heated by the heated susceptor 15000. The temperature of the air increases, which can generate aerosols. The cigarette 20000 is then conveyed to the user through the filter rod 22000 of the cigarette 20000.

[0038] If necessary, a cigarette 20000 is inserted into the aerosol generating device 10000. Even if the aerosol generating device 10000 does not have a heat source, the aerosol generating device 10000 can heat the susceptor 15000. can.

[0039] The battery 11000 supplies power to the aerosol generating device 10000. For example, the battery 11000 supplies power to the susceptor 15000 so that the susceptor 15000 is heated. It supplies power to the driver 14000 and the control unit 12000 with the power required to operate. The battery 11000 can be provided in the aerosol generating device 10000. It can supply the power required to operate displays, sensors, motors, etc.

[0040] The control unit 12000 controls the overall operation of the aerosol generating device 10000. For example, the control unit 12000 controls the power supplied from the battery 11000 to the coil 14000. The control unit 12000 can control the battery 11000 and the coil 14. 10000, as well as other components included in the aerosol generating device 10000. In addition, the control unit 12000 controls the state of each component of the aerosol generating device 10000. and determine whether the aerosol generating device 10000 is in an operable state. can.

[0041] The control unit 12000 includes at least one processor. It is implemented as an array of gates and is used with a general-purpose microprocessor. It may also be embodied as a combination of memory in which an executable program is stored. It is possible to realize the above-mentioned embodiment as hardware in the form of a method for manufacturing a semiconductor device. Any person with ordinary knowledge can understand this.

[0042] In the embodiment shown in FIG. 1, the coil 14000 of the aerosol generating device 10000 The coil is wound around the side of the space in which the cigarettes 20,000 are housed to generate an induced magnetic field. The susceptor 15000 is disposed at a position corresponding to the position of the coil 14000. Heat is also generated by the induced magnetic field generated by coil 14000.

[0043] Induction heating is a method of heating a magnetic material by applying an alternating magnetic field (a This refers to a method of generating heat from a magnetic material by applying an external alternating magnetic field. A magnetic material that generates heat due to a field is also called a susceptor. Or it is included in the cigarette 20000 by the shape of a strip or the like. As mentioned above, the susceptor is not contained within the cigarette 20000 but is instead an aerosol. It can be placed in the generating device 10000.

[0044] When an alternating magnetic field is applied to a magnetic material, the magnetic material generates eddy current loss and heat loss. Energy loss occurs due to hysteresis loss, and the amount of energy lost is The magnetic material is released as thermal energy. The larger the wave number, the more heat energy can be released from the magnetic material. 0000 is a method of releasing thermal energy from a magnetic material by applying an alternating magnetic field to the magnetic material. The thermal energy emitted from the body can be transferred to the cigarette 20,000.

[0045] According to an embodiment, the susceptor 15000 may comprise metal or carbon. 5000 is made of ferrite, ferromagnetic alloy, stainless steel (s It may contain at least one of stainless steel (Stainless Steel) and aluminum (Al). The Susceptor 15000 is made of graphite, molybdenum, and silicon carbide. Silicon carbide, niobium, nickel alloy, metal film (metal film), ceramics such as zirconia, nickel (Ni) and cobalt At least one of the transition metals such as Co, and semimetals such as boron (B) and phosphorus (P) It may also include one.

[0046] An aerosol generating device 100 in which the susceptor 15000 is not inside the cigarette 20000 00 has various advantages. For example, the susceptor material is If the powder is not distributed evenly around the area, the aerosol and flavor will be unevenly distributed. The susceptor 15000 is provided in the aerosol generating device 10000. The temperature of the susceptor 15000, which is heated by induction heating, is directly measured and the air The temperature of the susceptor 15000 is then adjusted to the temperature of the sol generator 10000. Exquisite control is exercised.

[0047] As mentioned above, the coil 14000 may be powered by the battery 11000. The control unit 12000 of the aerosol generating device 10000 controls the current flowing through the coil 14000. By controlling the magnetic field, a magnetic field is generated, and an induced current is generated in the susceptor 15000 due to the influence of the magnetic field. This induction heating phenomenon is based on Faraday's Law of Induction. It is a well-known phenomenon explained by the law of transmission and Ohm's Law. This refers to the phenomenon that when the magnetic induction in a conductor changes, a changing electric field is generated within the conductor. do.

[0048] As mentioned above, when an electric field is generated in a conductor, eddy currents are propagated according to Ohm's law. Eddy currents flow in conductors and generate heat that is proportional to the current density and the conductor resistance.

[0049] In other words, when power is supplied to the coil 14000, A magnetic field can be generated. An alternating current is applied to the coil 14000 from the battery 11000. In this case, the magnetic field formed inside the coil 14000 changes direction periodically. 5000 is formed inside the coil 14000 and is exposed to an alternating magnetic field that changes direction periodically. When the aerosol generating device 10000 is inserted, the susceptor 15000 generates heat and the aerosol generating device 10000 receives heat. Galette 20000 can be heated.

[0050] If the amplitude or frequency of the alternating magnetic field generated by coil 14000 is changed, The temperature of the susceptor 15000 that heats the reed 20000 also changes. The power supplied to the coil 14000 is controlled to generate an alternating current generated by the coil 14000. The amplitude or frequency of the magnetic field can be adjusted, thereby controlling the temperature of the susceptor 15000. do.

[0051] As an example, the coil 14000 may be embodied as a solenoid. The material of the conductor that constitutes the lenoid may be copper (Cu), but is not limited to this. However, materials that have low resistivity and allow a high current to flow are silver (Ag), gold (Gold), and copper (Cu). (Au), aluminum (Al), tungsten (W), zinc (Zn) and nickel (N i) Any one of them or an alloy containing at least one of them is used for the conductor that constitutes the solenoid. It can also be used as a wire material.

[0052] On the other hand, as another example, the aerosol generating device 10000 may be spun by an electrical resistance heater. Galette 20000 can be heated. For example, a cigarette can be used as an aerosol generating device. If inserted in 10000, an electric resistance heater will be used instead of susceptor 15000. The heater is located inside the cigarette 20000. The temperature of the medium can be increased to generate aerosols.

[0053] For example, an electrically resistive heater includes a conductive track through which a current is applied. The heater can be heated by the flow of the liquid. However, the heater is not limited to the above-mentioned example. As long as the product is heated to a desired temperature, there are no restrictions. The desired temperature is The aerosol generating device 10000 may already have the setting, or may be manually set by the user. It may be determined.

[0054] In FIG. 1, a susceptor 15000 is disposed so as to be inserted into a cigarette 20000. For example, the susceptor 15000 is shown as a includes a tubular heating element, a plate heating element, a needle heating element, or a rod heating element, Depending on the shape of the cigarette 20000, the cigarette 20000 can be heated internally or externally.

[0055] Moreover, in the aerosol generating device 10000, a plurality of susceptors 15000 are arranged. At this time, the susceptors 15000 are arranged so as to be inserted into the cigarettes 20000. Alternatively, the cigarette 20000 may be disposed outside the cigarette 20000. A part of the susceptor 15000 is arranged so as to be inserted inside the cigarette 20000. The remaining part may be disposed outside the cigarette 20000. The shape of the 0 is not limited to the shape shown in FIG. 1, but may be made into various shapes.

[0056] On the other hand, the aerosol generating device 10000 includes a battery 11000, a control unit 12000, In addition to the coil 14000 and the susceptor 15000, a general-purpose component may be further included.

The device includes at least one sensor (e.g., a puff sensor, a temperature sensor, a cigarette insert, The input sensor may include a power supply.

[0057] In addition, the aerosol generating device 10000 can be used even when the cigarette 20000 is inserted. It is also made so that outside air can flow in or inside gas can flow out.

The cradle and the aerosol generating device can be used to charge the battery 11000 of the cradle. With the position 10000 bonded, the susceptor 15000 is heated.

[0059] The Cigarette 20000 is also similar to a typical combustible cigarette. The head 20000 includes a first portion 21000 containing an aerosol generating material and a filter, etc. Alternatively, the second portion 220 of the cigarette 20000 may be divided into a second portion 220 00 also contains aerosol-forming materials. For example, An aerosol generating substance may be inserted into second portion 22000.

[0060] The entire first portion 21000 is inserted into the aerosol generating device 10000, and the second portion The portion 22000 may be exposed to the outside or may be inside the aerosol generating device 10000. Only a part of the first part 21000 is inserted into the first part 21000 and the second part 22000. A part of the second portion 22000 can be inserted into the mouth of the user. The user inhales the aerosol while holding the second portion 22000 in his / her mouth. At this time, the aerosol can be absorbed by the outside air passing through the first portion 21000. The aerosol is generated by passing through the second portion 22000 into the mouth of the user. It is transmitted.

[0061] As an example, the outside air may be at least one aerosol generated in the aerosol generating device 10000. For example, the aerosol generating device 10000 may be formed in the aerosol generating device 10000. The opening and closing of the air passage and / or the size of the air passage can be adjusted by the user. As a result, the amount of atomization, the smoking sensation, etc. can be adjusted by the user. The cigarette 20000 is inserted through at least one hole formed in the surface of the cigarette 20000. The power flows into the interior of port 20000.

Since the heat transfer caused by the heat transfer is efficiently blocked, the heat transferred to the inner wall 161 is not transferred to the inner space 163. , and transmission to the outside of the outer wall 162 can be blocked.

[0079] In order to maintain the internal space 163 of the heat dissipation structure 160 at a vacuum, The wall 161, the outer wall 162, the upper wall and the lower wall may be hermetically joined. 61, the outer wall 162, the upper wall and the lower wall may be fabricated separately and then joined together. , the inner wall 161, the outer wall 162, the upper wall and the lower wall may be integrally molded.

[0080] FIG. 4A is a detailed cross-sectional view of a portion of the aerosol generating device shown in FIG. 3, and FIG. 4A shows the induced magnetic field in the embodiment shown in FIG. 4C according to another embodiment. FIG. 2 is a detailed cross-sectional view of a portion of the aerosol generating device.

[0081] Referring to FIG. 4A, the aerosol generating device 100 is disposed inside a heat dissipation structure 160. The heating element may include a coil 140 , a susceptor 150 , and a shield 170 .

[0082] As described above, the coil 140 generates an induction magnetic field and surrounds the receiving space 132. The susceptor 150 is arranged as shown in FIG. This generates heat and heats the cigarette 20 contained in the containing space 132.

[0083] The coil 140 is disposed inside the heat dissipation structure 160 and is connected to the heat dissipation structure 160 by a desired For example, the coil 140 and the heat dissipation structure 160 may be spaced apart from each other by a certain distance d. The fixed distance d is also 1 mm to 2 mm.

[0084] As shown in FIG. 4A, the susceptor 150 is inserted into the cigarette 20. In particular, the susceptor 150 may be rod-shaped with a pointed end, but is not limited thereto. For example, referring to FIG. 4C, the susceptor 150′ of the aerosol generating device 100 is The cigarette 20 is not inserted into the cigarette holder 20 but is disposed outside the cigarette holder 20. Thus, the susceptor 150' heats the exterior of the cigarette 20 to generate an aerosol. can be done.

[0085] The aerosol generating apparatus 100 further includes a support 151 for supporting the susceptor 150 and a support The support 151 may include a first support wall 152 connected to the support 151 to form the receiving space 132. The portion 151 and the first support wall 152 may be manufactured independently and then hermetically coupled to each other. In the embodiment, the support portion 151 and the first support wall 152 may be integrally formed. The coil 140 surrounds a first support wall 152 such that the susceptor 150 is disposed thereon.

[0086] The shielding portion 170 can shield the induced magnetic field generated by the coil 140. As shown in the figure, the induced magnetic field generated by the coil 140 is shielded by the shielding portion 170. Therefore, the induction current generated in the coil 140 is generated only inside the coil 140. The inductive magnetic field may be concentrated at the susceptor 150. FIG. 4B shows an inductive magnetic field generated on one side of the coil 140. Only the induced magnetic field is shown, and the same induced magnetic field is generated on the other side of the coil 140.

[0087] For example, the shielding portion 170 is a material that shields the induced magnetic field, such as a nanocrystal or a ferrite sheet. However, the material of the shielding portion 170 is as described above. is not restricted by

[0088] The shielding portion 170 is a space formed between the coil 140 and the heat dissipation structure 160. and may be disposed so as to surround the coil 140. Thus, the shielding portion 170 The induction magnetic field generated by the coil 140 is emitted to the outside of the aerosol generating device 100. In this case, the shielding portion 170 is adjacent to the coil 140. It can be placed.

[0089] A shielding portion 170 is disposed adjacent to the coil 140 in the space between the coil 140 and the heat dissipation structure 160. Therefore, an air gap may be formed between the heat dissipation structure 160 and the shielding portion 170. As a result, the air gap formed between the heat dissipation structure 160 and the shielding portion 170 Therefore, the induced magnetic field leaking from the shielding portion 170 can be prevented from reaching the heat dissipation structure 160. At the same time, the heat generated by the susceptor 150 is dissipated through the air gap. The heat reaching the thermal structure 160 may be reduced.

[0090] The heat dissipation structure 160 may be made of a metal material. 60 is stainless steel, aluminum, potassium, sodium, white It may also be made of a paramagnetic metal, including gold and SUS. Even when the heat dissipation structure 160 is fabricated by the induction magnetic field generated by the coil 140, As a result, the shielding portion 170 is disposed between the coil 140 and the heat dissipation structure 160. It can be placed.

[0091] In addition, the heat dissipation structure 160 made of a metal material passes through the above-mentioned shielding portion 170 and the air gap. It can absorb the induced magnetic field, maximizing the electromagnetic wave shielding effect. .

[0092] On the other hand, the heat dissipation structure 160 is made of a non-metallic material. In such a case, the coil Since the induction magnetic field of 140 does not generate electromagnetic induction, heat is not generated by the induction magnetic field. In this case, the heat dissipation structure 160 made of a non-metallic material is not Only heat generated from the 0 can be transferred, so as mentioned above, a suitable air gap must be formed. If such a structure is provided, the heat transfer to the heat dissipation structure 160 may be reduced. The shielding effect of the structure 160 against the induced magnetic field is reduced compared to that of metal. 70 may be disposed outside the coil 140 .

[0093] According to the embodiment, the shielding portion 170 and the heat dissipation structure 160 are arranged together, so that the aerosol The electromagnetic waves of the aerosol generating device 100 are prevented from being transmitted to the outside, and This makes it possible to prevent the heat generated inside the device 100 from being transferred to the outside.

[0095] Referring to FIG. 5A, the aerosol generating device 200 includes a support member for supporting a susceptor 250. 251, a first support wall 252 connected to the support portion 251 to form the receiving space 232, A second support wall 253 and a second support wall 254 are disposed outside the first support wall 252 and spaced apart from the support wall 252. A connecting wall 254 that connects the first support wall 252 and the second support wall 253 may be included.

[0096] Since the first support wall 252 and the second support wall 253 are spaced apart from each other, the coil 240 can be accommodated therein. The coil 240 is fixed inside the coil receiving space. It is possible.

[0097] The support portion 251, the first support wall 252, the second support wall 253 and the connecting wall 254 are manufactured independently. Optionally, the support portion 251, the first support wall 252, and the second support wall 253 may be formed in a manner that allows the support portion 251, the first support wall 252, and the second support wall 253 to be airtightly joined to each other. The two support walls 253 and the connecting wall 254 may be integrally formed.

[0098] The shielding portion 270 may be disposed adjacent to the second support wall 253. 0 may be disposed adjacent to the coil 240.

[0099] As described above, an air gap is formed between the heat dissipation structure 260 and the shielding portion 270. As a result, an air gap is formed between the heat dissipation structure 260 and the shielding portion 270. Therefore, the induced magnetic field leaking from the shielding portion 270 is prevented from reaching the heat dissipation structure 260. At the same time, the heat generated from the susceptor 250 is dispersed in the process of passing through the air gap. As a result, the amount of heat reaching the heat dissipation structure 260 may be reduced.

[0100] 5B, unlike FIG. 5A, the shielding portion 270′ is formed on the inner wall 2 of the heat dissipation structure 260. 61. Therefore, between the coil 240 and the shielding portion 270′, An air gap may be formed, which allows the induction magnetic field generated by the coil 240 and the susceptor The heat generated from the heater 250 is dispersed through the air gap, so it does not reach the shielding part 270'. The induced magnetic field and the heat reaching the heat dissipation structure 260 can both be reduced.

[0101] FIG. 6 is a detailed cross-sectional view of a portion of an aerosol generating device according to yet another embodiment.

It is possible to detect the amount of change in inductance caused by the emission of a cigarette lighter. The cigarette recognition sensor 380 includes a sensing coil (not shown) and detects the insertion and extraction of the cigarette 20. The inductance output value can be output based on the frequency value varied by the

[0104] For this purpose, the cigarette 20 is, for example, an electromagnetic inductor (not shown). The electromagnetic inductor may include an inductor of the cigarette recognition sensor 380. Electromagnetic inductors are conductors and magnets in which eddy currents are induced. For example, the electromagnetic inductor may be a metal material, a magnet, or the like. The magnetic material may include magnetic ink, magnetic tape, etc. Metallic materials such as minium, but not limited to them, electromagnetic induction The body may include, without limitation, a substance that changes the inductance of the cigarette recognition sensor 380. That's fine too.

[0105] As shown in FIG. 6, the cigarette recognition sensor 380 includes a coil 340 and a shielding portion 37. 0. The cigarette recognition sensor 380 detects the electromagnetic induction of the cigarette 20. Therefore, the cigarette recognition sensor 380 recognizes the cigarette 20 by detecting the presence of the shielding portion 370. When it is arranged outside, the insertion and extraction of the cigarette 20 cannot be detected. Therefore, the cigarette recognition sensor 380 is located inside the shielding portion 370, particularly Since the coil 340 and the shielding portion 370 are disposed in the vicinity of the coil 340, the insertion and extraction of the cigarette 20 can be performed smoothly. How can you sense it?

[0106] The control unit determines whether the cigarette is a cigarette or not based on the amount of change in inductance of the cigarette recognition sensor 380. It can be determined whether or not to insert or extract 20.

[0107] For example, when the control unit detects the insertion of the cigarette 20, the control unit Specifically, the control unit can automatically perform the heating operation when the cigarette recognition sensor 380, when the cigarette 20 is detected to be inserted, the battery turns on the coil 34. The coil 340 generates an induced magnetic field. By this, the susceptor 350 can be heated. The reed 20 is heated, which may generate an aerosol.
