[0058] An embodiment of the present application provides an aerosol generating device 100, such as Figure 1 As shown, the aerosol generating device 100 includes a shell 10, and the shell 10 has a first end 11 and a second end 12 which are arranged opposite to each other in the longitudinal direction. The first end 11 is provided with a chamber 111, and the chamber 111 is used to receive the aerosol product 200 used in conjunction with the aerosol generating device 100, that is, the aerosol product 200 can be accommodated in the aerosol generating device 100 through the chamber 111.

[0059] A heating component 13, a power supply unit 14 and a main board 15 are provided in the shell 10. A controller of the aerosol generating device 100 is provided on the main board 15. The heating component 13 and the power supply unit 14 are electrically connected to the main board 15, so that the controller can control the power supply unit 14 to provide electric energy to the heating component 13. The heating component 13 can generate heat under the action of the electric energy. When the aerosol product 200 is accommodated in the chamber 111, the heating component 13 heats the aerosol product 200 accommodated in the chamber 111, thereby causing part of the active substances in the aerosol product 200 to volatilize due to heat to generate aerosol. The user can inhale the aerosol by inhaling on the aerosol product 200. The power supply unit 14 can be a rechargeable or non-rechargeable battery cell.

[0060] The heating assembly 13 includes a cylindrical body 131 and a heating element 132 attached to the outer wall of the cylindrical body 13. The cylindrical body 131 is hollow. When the aerosol product 200 is accommodated in the chamber 111, at least a part of it is accommodated in the cylindrical body 131. The heating element 132 can generate heat when it is powered on, and then transfers the heat to the aerosol product 200 through the cylindrical body 131, so that the aerosol product 200 can be heated. At this time, the material of the cylindrical body 131 is made of a high thermal conductivity material to efficiently transfer the heat generated by the heating element 132 to the aerosol product 200. The high thermal conductivity material can be a metal or a ceramic material, and the ceramic material can be any one of oxides, nitrides, carbides, borides, etc.

[0061] Or, if Figure 2 As shown, in some embodiments, the outer wall of the cylindrical body 131 of the heating component 13 is wound with an induction coil 133. When the controller controls the power supply unit 14 to pass an alternating current into the induction coil 133, the induction coil 133 generates an alternating magnetic field under the action of the alternating current. The alternating magnetic field passes through the cylindrical body 131, thereby inducing eddy currents on the cylindrical body 131. The cylindrical body 131 can generate heat under the action of the eddy currents and transfer the heat to the aerosol product 200.

[0062] In order to induce eddy currents on the cylindrical body 131, the material of the cylindrical body 131 can be any one of graphite, molybdenum, silicon carbide, stainless steel, niobium, aluminum, nickel, iron, copper, nickel-containing compounds, titanium, and metal material composites. In some embodiments, in order to better induce eddy currents to improve heating efficiency, the material of the cylindrical body 131 is preferably ferromagnetic material or composed of ferromagnetic materials, such as ferrite iron, ferromagnetic alloys (such as ferromagnetic steel or stainless steel), ferromagnetic particles, and ferrites.

[0063] Furthermore, in some embodiments, the aerosol generating device 100 may also adopt infrared heating. Specifically, an infrared electrothermal coating may be coated on the outer wall of the cylindrical body 131, and the infrared electrothermal coating is used to receive electric power to generate heat, thereby generating infrared rays of a certain wavelength, such as far infrared rays of 8 μm to 15 μm. When the wavelength of the infrared rays matches the absorption wavelength of the aerosol product 200, the energy of the infrared rays is easily absorbed by the aerosol product 200, thereby generating heat on the aerosol product 200.

[0064] Aerosol product 200 preferably uses a tobacco-containing material that releases volatile compounds from the product when heated; or it can also be a non-tobacco material that can be heated and suitable for electric heating and smoking. Aerosol product 200 preferably uses a solid matrix, which can include one or more of powder, particles, fragments, strips or sheets of one or more of herb leaves, tobacco leaves, homogenized tobacco, and expanded tobacco; or the solid matrix can contain additional tobacco or non-tobacco volatile flavor compounds to be released when heated.

[0065] And, in some embodiments, as Figure 15-17 As shown, the heating assembly 13 includes a cylindrical body 131 and an induction coil (not shown) wound on the outer wall of the cylindrical body 31. A susceptor 134 extends longitudinally in the cylindrical body 31. The susceptor 134 is configured to be penetrated by a changing magnetic field and generate heat, and the end of the susceptor 134 is configured to be pin-shaped or sheet-shaped so as to be inserted into the aerosol product 200 for heating. The main board 15 controls the power supply unit 14 to pass an alternating current into the coil. The coil generates a changing magnetic field under the action of the alternating current. The changing magnetic field penetrates the susceptor 134 and induces eddy current on the susceptor 134. The susceptor 134 generates heat under the action of the eddy current effect and the hysteresis effect, thereby heating the aerosol product 200. The aerosol generating device 100 also includes a movable part 16, and the movable part 16 is formed with a receiving portion 161. The receiving portion 161 is used to receive at least a part of the aerosol product 200. The side wall of the cylindrical body 131 is provided with an opening 1311, and the side wall of the receiving portion 161 is provided with a notch 1611, so that the movable member 16 can move in the horizontal direction (see FIG. Fig.15When the movable member 16 moves to the first position, the receiving portion 161 passes through the opening 1311 and is received in the cylindrical body 131, and the sensor 134 passes through the notch 1611 and is received in the receiving portion 161. When the aerosol product 200 is inserted into the aerosol generating device 100, the sensor 134 can be inserted into the aerosol product 200 received in the receiving portion 161 for heating. Fig.17 When the movable member 16 moves from the first position to the second position, the sensor 134 can move out of the receiving portion 161 through the notch 1611, and the receiving portion 161 moves out of the cylindrical body 131 through the opening 1311, as shown. Fig.15 shown.

[0066] When the movable member 16 moves from the first position to the second position, or moves from the second position to the first position, the sensor 134 passes through the notch 1611 to be accommodated in the accommodating portion 161, or passes through the notch 1611 to move out of the accommodating portion 161. During this process, the sensor 134 is in contact with the wall 1612 of the notch 1611, so that there is a relative friction force between the wall 1612 and the surface of the sensor 134, and then the solid residue remaining after heating adhering to the surface of the sensor 134 can be scraped off through the friction wall 1612 to clean the sensor 134 and avoid excessive accumulation of solid residue on the sensor 134.

[0067] Thus, through the above method, when the user needs to use the aerosol generating device 100 for inhalation, the movable part 16 can be moved to the first position, and the sensor 134 is relatively moved to the receiving portion 161. The user inserts the aerosol product 200, and the sensor 134 can be inserted into the aerosol product 200 for heating; and when the inhalation is completed, the user first pulls the aerosol product 200 out of the receiving portion 161, and then moves the movable part 16 back and forth between the first position and the second position in the horizontal direction. At this time, the wall 1612 of the notch 1611 and the surface of the sensor 134 are repeatedly rubbed, so that the solid residue remaining in the sensor 134 due to this inhalation can be removed in time.

[0068] The heating component 13, the power supply unit 14 and the main board 15 have corresponding thicknesses. Usually, the thicknesses of the heating component 13 and the power supply unit 14 are greater than the thickness of the main board 15, so as to reduce the overall size of the aerosol generating device 100 and thus improve the portability of the aerosol generating device 100. Figure 3As shown, the shell 10 includes a first part 110 and a second part 120, and the thickness of the first part 110 is greater than the thickness of the second part 120, so that the heating component 13 and the power supply unit 14 can be placed in the first part 110, and at least a part of the mainboard 15 can be placed in the second part 120, thereby reducing the overall size of the aerosol generating device 100, and also making the aerosol generating device 100 present an appearance of inconsistent thickness, so as to improve the novelty and originality of the appearance of the aerosol generating device 100.

[0069] In some embodiments, the thickness of the first portion 110 may be consistent or inconsistent. When the thickness of the first portion 110 is inconsistent, the first portion 110 may be set according to the specific thickness of the heating component 13 and the power supply unit 14. For example, when the thickness of the heating component 13 is greater than the thickness of the power supply unit 14, the heating component 13 may be placed in a thicker area, and the power supply unit 14 may be placed in a thinner area. Preferably, regardless of whether the thickness of the heating component 13 and the power supply unit 14 is consistent, the thickness of the first portion 110 is consistent to improve the aesthetics of the aerosol generating device 100.

[0070] In some embodiments, Figure 3 As shown, the first part 110 and the second part 120 are longitudinally extended side by side between the first end 11 and the second end 12, so that the overall appearance of the aerosol generating device 100 is thick on the left and thin on the right. Preferably, the thickness of the second part 120 does not exceed 6 mm. Since the aerosol product 200 is usually in the shape of a cigarette, in order to accommodate and evenly heat the aerosol product 200, the first part 110 can be roughly cylindrical. In this case, Figure 1 or Figure 2 As shown, the power supply unit 14 can adopt a cylindrical battery core of 18650 type, and the heating component 13 and the power supply unit 14 can be arranged vertically in sequence, so that the heating component 13 and the power supply unit 14 can be placed in the first part 110, and the main board 15 can be longitudinally extended in the second part 120, so as to achieve the following Figure 3 And, in some embodiments, as Figure 4As shown, in order to further reduce the volume of the aerosol generating device 100 and improve the portability of the aerosol generating device 100, the second part 120 includes a side wall 121 extending between the first end 11 and the second end 12, and at least a portion of the side wall 121 extends obliquely toward the second end 12 and gradually approaches the first part 110, so that the overall size of the aerosol generating device 100 can be further reduced by the oblique portion, so that the aerosol generating device 100 can be more conveniently held. Alternatively, in some embodiments, at least a portion of the side wall 121 can also extend toward the first end 11, or extend toward both the first end 11 and the second end 12. Further in some embodiments, as Figure 3 As shown, the first portion 110 and the second portion 120 are arranged on both sides of the longitudinal axis Y of the housing 10 , so that the first portion 110 and the second portion 120 are symmetrically arranged to make the aerosol generating device 100 more beautiful.

[0071] In some embodiments, Figure 5 and Figure 6 As shown, the heating assembly 13 and the main board 15 are arranged vertically on one side of the housing 10, and the power supply unit 14 extends longitudinally on the other side of the housing 10. The second portion 120 extends from the first portion 110 to the second end 12, and the main board 15 extends longitudinally in the second portion 120, thereby achieving the following Figure 6 The outer shape shown is that the outer shape of the shell of the aerosol generating device 100 is thinner in the lower left part and thicker in other parts. It should be noted that the main board 15 can be arranged in the second part 120 as a whole, or can be partially extended upward into the first part 110.

[0072] In some embodiments, Figure 7 As shown, the power supply unit 14 is a polymer battery cell, which usually has a wide width. The power supply unit 14 and the main board 15 are partially overlapped to save structural space. Specifically, the main board 15 includes a first section 151 and a second section 152. The second section 152 overlaps with the power supply unit 14. Figure 7 The dashed box shown in the figure is the section overlapping with the power supply unit 14, so that the second section 152, the power supply unit 14 and the heating component 13 can be arranged in the first part 110, and the first section 151 is arranged in the second part 120, so as to achieve the following Figure 8It is worth noting that the shell appearance of the aerosol generating device 100 is not limited to the above-mentioned shape. By flexibly arranging the positions of the heating component 13, the power supply unit 14 and the main board 15, the shell of the aerosol generating device 100 can present various shapes with inconsistent thicknesses, thereby reducing the overall size of the aerosol generating device 100 while making the appearance of the aerosol generating device 100 novel and original.

[0073] An embodiment of the present application also provides an aerosol generating system, such as Fig. 9 As shown, the aerosol generating system includes an aerosol generating device 100 and a charging device 200. The charging device and the aerosol generating device 100 are detachably connected. When the aerosol generating device 100 and the charging device 200 are connected, the charging device 200 can charge the aerosol generating device 100; and after being fully charged, the aerosol generating device 100 can be separated from the charging device 200.

[0074] The aerosol generating device 100 includes a housing 10, in which the above-mentioned heating component 13, power supply unit 14 and main board 15 are arranged. According to the thickness of the heating component 13, power supply unit 14 and main board 15, the shape of the housing 10 is configured as follows: Fig. 9 The shape shown is that the shell 10 has a first part 110 and a second part 120 extending between the first end 11 and the second end 12, wherein the thickness of the first part 110 is greater than the thickness of the second part 120, and the thicker heating component 13 and the power supply unit 13 are arranged in the first part 110, and the thinner mainboard 15 is arranged in the second part 120.

[0075] The charging device 200 is correspondingly provided with a receiving chamber 210 for receiving the second part 120, and the second part 120 can be inserted into the receiving chamber 210 in an adaptable manner. When the aerosol generating device 100 and the charging device 200 are connected, the aerosol generating device 100 can be fixed on the charging device 200, so that the charging device 200 can stably charge the aerosol generating device 100. In some embodiments, a snap fastener (not shown) can be provided on the second part 120, and a corresponding card slot is provided in the corresponding receiving chamber 210, so that when charging is required, the second part 120 can be inserted into the receiving chamber 210 so that the snap fastener is inserted into the card slot, thereby fixing the aerosol generating device 100 on the charging device 200. Of course, a card slot can also be provided on the second part 120, and a snap fastener can be provided in the receiving chamber 210 accordingly.

[0076] Alternatively, in some embodiments, a first magnetic member (not shown) is disposed on the second portion 120, and a second magnetic member (not shown) is correspondingly disposed on the charging device 200, so that the aerosol generating device 100 and the charging device 200 can be magnetically connected. Alternatively, in some embodiments, the second portion 120 can also be directly clamped in the receiving chamber 210, and the aerosol generating device 100 is fixed to the charging device 200 by clamping.

[0077] In some embodiments, Fig.10 As shown, the second part 120 includes a side wall 121 extending between the first end 11 and the second end 12, and a charging connection portion is provided on the side wall 121. The charging connection portion can be a conductive contact 1211. At this time, a spring pin (not shown) that can be adapted to abut against the conductive contact 1211 is provided in the receiving chamber 210. When the second part 120 is inserted into the receiving chamber 210, the spring pin is electrically contacted with the conductive contact 1211, so that the charging device 200 charges the aerosol generating device 100.

[0078] Or, in some embodiments, Fig.11 As shown, the charging connection portion may also be a charging interface 1212, in which case the corresponding receiving chamber 210 is provided with a charging terminal that can be inserted into the charging interface, for example, the charging interface may be a type-c interface, and the charging terminal is a type-c terminal. Figure 12-14 As shown, the side wall 121 is provided with a groove 122, and the charging interface 1212 is provided in the groove 122. At the same time, the groove 122 is also provided with a trigger button 1213 adjacent to the charging interface 1212, and a shielding member 123 that can slide along the groove 122. The shielding member 123 can move along the groove 122 between a first position and a second position. When the shielding member 123 moves to the first position, the shielding member 123 shields the charging interface 1212 and exposes the trigger button 1213. Fig.14 When the shielding member 123 moves from the first position to the second position, the shielding member 123 shields the trigger button 1213 while exposing the charging interface 1212, as shown Fig.13 The trigger button 1213 can be operated by the user, and the user can start the aerosol generating device 100 to start heating the aerosol product 200 by pressing the trigger button 1213 .

[0079] Therefore, by operating the shielding member 123 , it is possible to prevent the charging port 1212 and the trigger button 1213 from being operated at the same time, that is, to prevent the aerosol generating device 100 from being charged and heated at the same time, thereby effectively improving the safety performance of the aerosol generating device 100 .

[0080] In addition, since the charging interface 1212 is disposed on the side wall 121, the charging interface 1212 is relatively close to the heating component 13, and the heat generated by the heating component 13 will be partially transmitted through the charging interface 1212 and affect the user's use. With the above-mentioned shielding member 123, when the aerosol generating device 100 needs to be used, the user needs to move the shielding member 123 to the first position, at which time the shielding member 123 shields the charging interface 1212 and exposes the trigger button 1213. The user can press the trigger button 1213 to start the aerosol generating device 100, and at this time the shielding member 123 shields the charging interface 1212, which can effectively prevent the heat of the heating component 13 from being dissipated through the charging interface 1212, thereby avoiding the heat dissipated from causing discomfort to the user when the user uses the aerosol generating device 100.

[0081] And, in some embodiments, when the aerosol generating device 100 is connected and charged with the charging device by means of magnetic connection and conductive contact 1211, the conductive contact 1211 can be set on the side wall 121, and the first magnetic member can be set on the first end 11 and / or the second end 12 of the second part 120, and the corresponding position of the receiving chamber 210 of the charging device 200 is provided with a spring ejector pin and a second magnetic member, so that the magnetic direction can be different from the electrical connection direction. That is, at this time, the aerosol generating device 100 and the charging device 200 have a first direction of electrical connection, which is in the horizontal direction; and the aerosol generating device 100 and the charging device 200 have a second direction of magnetic connection, which is in the longitudinal direction, and the first direction and the second direction are perpendicular to each other.

[0082] Alternatively, in some embodiments, if the side wall 121 of the second portion 120 is arranged to be inclined toward the first portion 110 as in the above embodiment, the first direction and the second direction intersect. Also, in some embodiments, a conductive contact 1211 may be arranged at the first end 11 or the second end 12, and a first magnetic member may be arranged on the side wall 121, and the magnetic connection direction and the electrical connection direction may be different.
