Detailed Description
In order that the application may be readily understood, a more particular description thereof will be rendered by reference to specific embodiments that are illustrated in the appended drawings.
One embodiment of the present application proposes a method for generating an aerosol for an aerosol-generating system. In some implementations, the aerosol-generating system may comprise two or more parts that are separate from each other or that are replaced, which when combined form a complete combined use state of the aerosol-generating system, and which can be operated by a respective user to generate an aerosol.
In one embodiment, an aerosol-generating system comprises an aerosol-generating device; the aerosol-generating device may be selectively used in conjunction with at least two different types of consumer products to form. For example, in some implementations, the aerosol-generating device can be configured to cooperate with either of the first type of consumer product or the second type of consumer product selectively to create an aerosol-generating system.
And in some implementations, when the aerosol-generating device is configured such that it can only receive one consumer product at a time; for example, in some implementations, the aerosol-generating device can only receive one of the first type of consumer product or the second type of consumer product at a time, and cannot receive both of them at the same time.
And in some implementations, the aerosol-generating device may comprise a detection unit configured to detect the presence of a first type of consumer product or a second type of consumer product inserted into the device. In particular, the detection unit can be used to detect or identify the type of consumer product to which the aerosol-generating device is coupled, such that the operation of the aerosol-generating device, in particular, for example, the output of 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 a consumer product of a first type is inserted in combination with the aerosol-generating device, controlling the aerosol-generating device to start operation according to the first power output mode; and controlling the aerosol-generating device to start operating in accordance with the second power output mode when the detection unit detects that the second type of consumer product is inserted in combination with the aerosol-generating device.
In some specific alternative implementations, the detection unit may comprise a color sensor for determining the type of consumer product by detecting the color of the consumer product coupled to the aerosol-generating device.
For another example, in still other variations, the aerosol-generating device can determine the type of consumer product by detecting a physical characteristic of an electronic component in the consumer product. The aforementioned physical characteristics may include, for example, one or more of a resistance value, an inductance value, a voltage value, a capacitance value, a magnetic property, etc. of an electronic component in the consumer product. In this implementation the detection element may comprise a detection function circuit, such as a circuit module described below.
Or in yet other particular implementations, the first type of consumer product or the second type of consumer product each have a different heating element; the aerosol-generating device is capable of determining the type of consumer product by detecting a characteristic of a heating element in the consumer product.
Further in some implementations, the first type of consumer product may include a nebulizer that stores an aerosol-generating substrate and vaporizes at least one component of the aerosol-generating substrate to produce an aerosol. In some implementations, the aerosol-generating substrate may include glycerin, propylene glycol, or the like, which can be heated to vaporize to generate an aerosol.
And in some implementations, the second type of consumer product may include a solid aerosol-generating article that is formed into an aerosol for inhalation by heating the solid aerosol-generating article, volatilizing or releasing at least one component of the solid aerosol-generating article. In some implementations, the solid aerosol-generating article preferably employs tobacco-containing material that releases volatile compounds from the matrix upon heating; or may be a non-tobacco material capable of being heated and thereafter adapted for electrical heating for smoking. In some embodiments, the aerosol-generating article preferably employs a solid matrix, which may comprise one or more of a powder, granules, shredded strips, ribbons or flakes of one or more of vanilla leaves, dried flowers, volatile flavored herbal crops, tobacco leaves, reconstituted tobacco, expanded tobacco; or the solid substrate may contain additional volatile flavour compounds, whether tobacco or not, to be released when the substrate is heated.

And further according to arrow R4 in fig. 3, when the atomizer 100 is at least partially received or integrated within the receiving chamber 270, the air inlet 121 is located within the receiving chamber 270; and, when the nebulizer 100 is at least partially received or integrated within the receiving chamber 270, it is also possible to have the external air enter the air intake passage of the air intake port 121 of the nebulizer 100 defined by the aerosol-generating device 200 alone or by the combination of the nebulizer 100 and the aerosol-generating device 200. And, a sensing channel is also defined by the nebulizer 100 and the aerosol-generating device 200 in conjunction with which the airflow sensor 250 is in airflow communication with the air inlet 121 of the nebulizer 100, thereby enabling the airflow sensor 250 to sense the user's suction airflow on the nebulizer 100.
Specifically according to the transmission path of the negative pressure shown by arrow R3 in fig. 3, the sensing channel comprises:
A channel portion 291 located between the housing 10 of the nebulizer 100 and the inner side surface of the wall 232 defining the receiving chamber 270 and extending longitudinally or axially of the receiving chamber 270 and/or the aerosol-generating device 200 towards the proximal end 2110; or it may be described that when the housing 10 portion of the atomizer 100 is received in the receiving chamber 270, a gap or clearance is maintained between the housing 10 of the atomizer 100 and the inner side surface of the receiving chamber 270, and the passage portion 291 is defined by the gap or clearance;

And, the channel portion 291 and the channel portion 292 join at a communication port 2311 defined on the wall 232, thereby forming a sensing channel between the air inlet 121 of the atomizer 100 and the air flow sensor 250. And when the user sucks the nebulizer 100, a negative pressure is formed at the air inlet 121, and the negative pressure is sensed on the sensing surface of the airflow sensor 250 through the passage portion 291 and the passage portion 292 of the sensing passage and then transmitted to determine the user's suction. And, by communicating the channel portion 292 and the channel portion 291 and/or the receiving cavity 270 of the sensing channel through the communication port 2311 near the proximal end 2110 and/or the opening 271, it is advantageous to prevent the aerosol-generating substrate from entering into the channel portion 292, avoiding false triggering caused by non-pumping of the aerosol-generating substrate into the airflow sensor 250.
And further referring to fig. 3, an air intake passage is defined between the atomizer 100 and the proximal end 2110 of the aerosol-generating device 200 when the atomizer 100 is received within the receiving chamber 270; an air intake passage is formed between the nebulizer 100 and the proximal end 2110 of the aerosol-generating device 200 for external air to enter the receiving chamber 270 during suction so that external air can enter the receiving chamber 270 and thus the nebulizer 100. In particular, the aerosol-generating device 200 has grooves or the like on the surface of the proximal end 2110, thereby forming the above air intake channel when the surface of the proximal end 2110 is engaged and abutted by the atomizer 100 to provide a channel for external air to enter the receiving cavity 270.

Or in yet other variations, wall 232 is extended to be proximal 2110; and wall 232 is joined to wall 231 at proximal end 2110.
