[0063] In order to facilitate the understanding of the present application, the present application is described in more detail below in conjunction with the accompanying drawings and specific implementation methods.

[0064] One embodiment of the present application provides an aerosol generating system for generating aerosol. In some implementations, the aerosol generating system may include two or more parts that are separated or replaced from each other, which, when combined, form a complete combined use state of the aerosol generating system and can generate aerosol in response to user operations.

[0065] In one embodiment, the aerosol generating system includes an aerosol generating device; the aerosol generating device can be selectively used in combination with at least two types of consumer products of different types to form. For example, in some implementations, the aerosol generating device can be selectively used with any one of the first type of consumer products or the second type of consumer products to form an aerosol generating system to generate an aerosol.

[0066] In some implementations, the aerosol generating device is configured so that it can only receive one consumable product at a time; for example, in some implementations, the aerosol generating device can only receive one of the first type of consumable product or the second type of consumable product at a time, but not both of them at the same time.

[0067] In some embodiments, the aerosol generating device may include a detection unit, the detection unit detection system is configured to detect the presence of a first type of consumer product or a second type of consumer product inserted into the aerosol generating device. Specifically, the detection unit can be used to detect or identify the type of consumer product incorporated into the aerosol generating device, so that the operation of the aerosol generating device, in particular the output such as heating or power, is optimized to match or adapt to the corresponding first type of consumer product or second type of consumer product. For example, when the detection unit detects that the first type of consumer product is inserted into the aerosol generating device, the aerosol generating device is controlled to start operating in a first power output mode; and when the detection unit detects that the second type of consumer product is inserted into the aerosol generating device, the aerosol generating device is controlled to start operating in a second power output mode.

[0068] In some specific optional implementations, the detection unit may include a color sensor to determine the type of the consumable product by detecting the color of the consumable product combined with the aerosol generating device.

[0069] For example, in some implementation variations, the aerosol generating device can determine the type of the consumer product by detecting the physical properties of the electronic components in the consumer product. The aforementioned physical properties may include, for example, one or more of the resistance value, inductance value, voltage value, capacitance value, magnetism, etc. of the electronic components in the consumer product. In this implementation, the detection element may include a detection function circuit, such as the circuit module described below.

[0070] Or in some special implementations, the first type of consumer product or the second type of consumer product each has a different heating element; the aerosol generating device can determine the type of the consumer product by detecting the characteristics of the heating element in the consumer product.

[0071] In some implementations, the first type of consumer product may include an atomizer that stores a liquid base in a liquid state and vaporizes at least one component of the liquid base to generate an aerosol. In some implementations, the liquid base may include glycerin, propylene glycol, etc., which can be heated and vaporized to generate an aerosol.

[0072] In some implementations, the second type of consumer product may include a solid aerosol-generating product, which is heated to volatilize or release at least one component of the solid aerosol-generating product to form an aerosol for inhalation. In some implementations, the solid aerosol-generating product preferably uses a tobacco-containing material that releases volatile compounds from the matrix when heated; or it can also be a non-tobacco material that can be heated and suitable for electric heating and smoking. In some specific implementations, the aerosol-generating product preferably uses a solid matrix, which may include one or more of powder, particles, fragments, strips, or flakes of one or more of vanilla leaves, dried flowers, volatile aromatic herbs, tobacco leaves, homogenized tobacco, and expanded tobacco; or, the solid matrix may contain additional tobacco or non-tobacco volatile aroma compounds to be released when the matrix is ​​heated.

[0086] In some implementations, the aerosol generating device 200 generates a changing magnetic field through the receiving cavity 270 to induce heating of the consumer product; specifically, an induction heating element may be arranged in the consumer product, and when the consumer product is received in the receiving cavity 270, the changing magnetic field can penetrate and generate heat to heat the consumer product, thereby generating an aerosol. Figure 1 and Figure 2 As shown, the aerosol generating device 200 includes:

[0087] The coil support 230 surrounds and defines the receiving cavity 270; the coil support 230 is arranged near the proximal end 2110;

[0088] The induction coil 260 is arranged around the coil support 230 ; and the induction coil 260 is operably electrically connected to the circuit board 220 , so that a changing magnetic field can be generated in the receiving cavity 270 when an alternating current provided by the circuit board 220 flows through the induction coil 260 .

[0089] Specifically, the circuit of the circuit board 220 includes a capacitor, and forms an LC resonant circuit with the induction coil 260 through the capacitor; and the circuit board 220 drives the LC resonant circuit to oscillate at a predetermined frequency to form an alternating current flowing through the induction coil 260, thereby causing the induction coil 260 to generate a changing magnetic field that can penetrate the receiving cavity 270. In some implementations, the frequency of the alternating current supplied to the induction coil 260 by the circuit on the circuit board 220 is between 80KHz and 2000KHz.

[0090] In some embodiments, the induction coil 260 has approximately 5 to 15 turns; and the induction coil 260 has an axial length of approximately 5 to 15 mm.

[0091] according to Figure 1 and Figure 2 As shown, the aerosol generating device 200 further includes:

[0092] The air inlet 202 is arranged on the outer surface of the housing of the aerosol generating device 200 for allowing air to enter during inhalation; the air inlet 202 is arranged close to the proximal end 2110 .

[0093] according to Figure 1 and Figure 2 As shown, the inner bottom wall of the receiving cavity 270 is also provided with:

[0094] The first communication port 233 is in airflow communication with the air inlet 202 through the air inlet passage 205; thus, during suction, the outside air entering through the air inlet 202 enters the receiving chamber 270 through the first communication port 233;

[0095] The second communication port 234 is in airflow communication with the airflow sensor 250 through the sensing channel 251; thus, during inhalation, the airflow sensor 250 can sense the airflow when the user inhales through the sensing channel 251 and the second communication port 234 to determine the user's inhalation action.

Therefore, when the atomizer 100 is received in the receiving cavity 270, the magnetic attraction between the first magnetic element 280 and the magnetic second electrical contact 13 keeps the atomizer 100 against and combined with the end element 2113.
