The consumable may also comprise an aerosol generator, such as a heater, which in use releases heat to cause the aerosol-generating material to generate an aerosol. The heater may for example comprise a combustible material, a material which is heatable by electrical conduction, or a susceptor.
A susceptor is a material that can be heated by penetration with a varying magnetic field (e.g., an alternating magnetic field). The susceptor may be an electrically conductive material such that its penetration by a varying magnetic field results in inductive heating of the heating material. The heating material may be a magnetic material such that penetration thereof by a varying magnetic field results in hysteresis heating of the heating material. The susceptor may be electrically conductive and magnetic such that the susceptor may be heated by two heating mechanisms. The device configured to generate a varying magnetic field is referred to herein as a magnetic field generator.
An aerosol-modifying agent is a substance typically located downstream of the aerosol-generating region that is configured to modify the generated aerosol, for example by altering the taste, flavor, acidity or another characteristic of the aerosol. The aerosol modifier may be disposed in an aerosol modifier release member operable to selectively release the aerosol modifier. For example, the aerosol modifier may be an additive or an adsorbent. For example, the aerosol modifiers may include one or more of fragrances, colorants, water, and carbon adsorbents. For example, the aerosol modifier may be a solid, a liquid, or a gel. The aerosol modifier may be in powder, wire or particulate form. The aerosol modifier may be free of filter material.
An aerosol generator is a device configured to cause the generation of an aerosol from an aerosol-generating material. In some embodiments, the aerosol generator is a heater configured to subject the aerosol-generating material to thermal energy in order to release one or more volatiles from the aerosol-generating material to form an aerosol. In some embodiments, the aerosol generator is configured to cause generation of an aerosol from the aerosol-generating material without heating. For example, the aerosol generator may be configured to subject the aerosol-generating material to one or more of vibration, increased pressure, or electrostatic energy.
The present disclosure relates to aerosol delivery systems (which may also be referred to as vapor delivery systems), such as nebulizers or e-cigarettes. In the following description, the term "e-cigarette" or "e-cigarette" may be used at times, but it will be understood that this term may be used interchangeably with aerosol delivery system/device and electronic aerosol delivery system/device. Furthermore, as is common in the art, the terms "aerosol" and "vapor" and related terms such as "evaporation," "aerosolization," and "aerosolization" are often used interchangeably.
Aerosol delivery systems (e-cigarettes) typically, although not always, comprise a modular assembly comprising a reusable device portion and replaceable (disposable/consumable) cartridge components. Typically, the replaceable cartridge component will include an aerosol-generating material and a vaporiser (which may be collectively referred to as a "vaporiser"), and the reusable device portion will include a power supply (e.g. a rechargeable power supply) and control circuitry. It will be understood that these different parts may include additional elements depending on the function. For example, the reusable device portion will typically include a user interface for receiving user input and displaying operating status features, and the replaceable cartridge device portion in some cases includes a temperature sensor for helping control temperature. The cartridge is electrically and mechanically coupled to the control unit for use, for example using threads, bayonet or magnetic coupling with suitably arranged electrical contacts. When the aerosol-generating material in the cartridge is exhausted, or when the user wishes to switch to a different cartridge having a different aerosol-generating material, the cartridge may be removed from the reusable component and a replacement cartridge attached in its place. Systems and devices conforming to this type of two-piece modular configuration may generally be referred to as two-piece systems/devices.
Electronic cigarettes typically have a generally elongated shape. To provide a specific example, some embodiments of the present disclosure will be considered to include such a generally elongated two-piece system employing disposable cartridges. However, it will be appreciated that the basic principles described herein may equally be applied to different configurations, such as single-piece systems or modular systems comprising more than two parts, refillable devices and single-use disposable articles, as well as other general shapes, for example based on so-called box-mode high performance devices that typically have a box-like shape. More generally, it will be understood that certain embodiments of the present disclosure are based on aerosol delivery systems that are operatively configured to provide functionality in accordance with the principles described herein, and that the constructional aspects of the system configured to provide functionality in accordance with certain embodiments of the present disclosure are not of primary importance.
As described in the background art, in the aerosol supply system in the prior art, the expected suction resistance is usually achieved by setting the size of the air inlet, however, the air inlet is directly contacted with the outside, and is greatly influenced by the outside, such as easy to block, deform and the like, so that the actual air inflow is inconsistent with the expected suction resistance, and the expected suction resistance is difficult to achieve. Based on the above, the application provides a new structure of an aerosol supply system, which can realize that the air flow finally entering the atomization cavity is regulated through the parts except the air inlet hole, so that the cartridge achieves the expected suction resistance.
Embodiments of the present application will be described in detail below with reference to the accompanying drawings.
Example 1
Fig. 1 is a schematic structural view of a cartridge of an aerosol provision system according to an embodiment of the present application, and fig. 2 is a schematic sectional view of a cartridge of an aerosol provision system according to an embodiment of the present application, and referring to fig. 1 and 2, the cartridge of the aerosol provision system generally includes a cartridge case 100, a mouthpiece 200, a liquid storage bin 300, and an atomizing core 400. Wherein, the cartridge housing 100 is internally formed with a containing space, an atomizing cavity 410 and an air channel 500, the atomizing cavity 410 is in fluid communication with the air channel 500, and the liquid storage bin 300, the atomizing core 400 and other components are all or at least partially arranged in the containing space. The reservoir 300 has a reservoir 310 formed therein, the reservoir 310 for containing an aerosol-generating material, such as a smoke oil, and the atomizing wick 400 includes an atomizing chamber 410 for containing a heater. The nebulization chamber 410 is in fluid communication with the reservoir chamber 310 such that aerosol-generating material in the reservoir chamber 310 enters the nebulization chamber 410 and is heated by the heater assembly to form an aerosol. The nebulizing chamber 410 is in fluid communication via the outlet of the airway nozzle piece 200 so that aerosol is drawn from the outlet of the nozzle piece 200 by the user. In the embodiment of the present application, the cartridge housing 100 and the suction nozzle 200 are not specifically limited, and may be selected or set according to the actual requirements of the product without departing from the concept of the present application.
The atomizing core includes at least a base 460 of the atomizing core for forming a bottom wall of the atomizing chamber 410, and an air blocking hole 600 is provided on the base 460 of the atomizing core, the air blocking hole 600 being formed as an air flow inlet of the air passage, and a fluid flux at the air blocking hole 600 being minimum in the air passage. Through set up the gas cut off hole on the base of atomizing core, and set up the fluid flux of gas cut off hole department minimum in the air flue to realize adjusting the airflow that finally gets into the atomizing chamber through the part beyond the inlet port, make the cartridge reach expected suction resistance.
It will be appreciated that the aerosol supply system is provided with an inlet passage (not shown) and an inlet port in communication with each other, the inlet passage (not shown) being in communication with the external atmosphere of the aerosol supply system via the inlet port (not shown). Since the cutoff orifice 600 forms an air flow inlet of the air passage 500, the air passage 500 communicates with the atomizing chamber, so that the atomizing chamber 410 communicates with the external atmosphere.
