Description

System comprising resistance-absorbing adjusting assembly

Technical Field

The present invention relates to the field of aerosol provision, and in particular to a system comprising a resistance-to-draw adjustment assembly.

Background

When a certain amount of air is sucked into the electronic cigarette holder, a certain vacuum pressure is generated at the suction end to prevent the air from being continuously pumped out. This pressure is the resistance to inhalation, simply referred to as the resistance to inhalation.

The absorption resistance has an important influence on the sensation of mouth. The greater the resistance to draw, the less air is contained in each puff, the higher the smoke content of the tobacco tar, and the greater the throat feel. However, excessive suction resistance can result in excessive suction effort. Because each person has different taste preference and different sucking habit, in order to attract consumers and meet the demands of more consumers, it is necessary to add a device for adjusting sucking resistance in the electronic cigarette structure.

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.

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 supply systems (which may also be referred to as vapor supply 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 supply system/device and electronic aerosol supply 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 provision 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.

The embodiment provides a suction resistance adjusting component, which can be arranged in an air flow channel of an aerosol supply module or a non-consumption atomization heating simulation device and used for adjusting the ventilation volume of the aerosol supply module or the non-consumption atomization heating simulation device. Wherein the aerosol provision module is an aerosol provision device or an aerosol-generating article, the aerosol provision device being configured to heat the aerosol-generating article or the atomizing module of the liquid matrix. The non-consumption atomization heating simulation device is a simulation device of an aerosol-generating product, is assembled on the aerosol supply device to perform heating or suction simulation, can monitor and obtain related data in the heating or suction process, such as heating temperature, suction parameters and the like, does not need to consume the aerosol-generating product, and saves test cost.

Referring to fig. 3 and 4, the resistance and suction adjustment assembly 10 includes a first adjustment element 101 and a second adjustment element 102, the first adjustment element 101 having an air passage 103 formed therein, the air passage 103 being in fluid communication with an air flow passage of the aerosol provision module 20 or a non-consumable atomizing heating analog device. The second adjusting element 102 can move relative to the first adjusting element 101 to change the exposed area of the air duct 103, thereby changing the airflow flux of the resistance-absorbing adjusting element, and realizing the effect of adjusting the ventilation of the airflow channel.

The resistance adjustment assembly 10 may be positioned anywhere in the airflow path. When the resistance-absorbing assembly 10 is disposed at the start position or the end position of the air flow passage, the resistance-absorbing assembly 10 is disposed at the outer surface of the aerosol provision module 20 or the non-consumable atomizing heating simulation device, as shown in fig. 2. When the resistance-absorbing assembly 10 is disposed in a section between the start position and the end position of the air flow passage, the resistance-absorbing assembly 10 is inside the aerosol provision module 20 or the non-consumable atomizing heating simulation device, as shown in fig. 1.

When the resistance-to-suction adjustment assembly 10 is provided in the initial or final position of the airflow passage, the resistance-to-suction adjustment assembly 10 may be provided as a separate component on the aerosol-supply module 20 or the non-consumable aerosol-heating simulation device in one alternative, and the first adjustment element 101 or the second adjustment element 102 may be configured as part of the outer surface of the aerosol-supply module 20 or the non-consumable aerosol-heating simulation device in another alternative. When the resistance-to-suction adjustment assembly 10 is provided in a section between the start position and the end position of the air flow channel, in an alternative, the resistance-to-suction adjustment assembly 10 may be provided as a separate component in the aerosol-supply module 20 or the non-consumable aerosol-heating simulation device, in an alternative, the first adjustment element 101 may be configured as part of the internal structure of the aerosol-supply module 20 or the non-consumable aerosol-heating simulation device, and the second adjustment element 102 may be configured as part of the internal structure of the aerosol-supply module 20 or the non-consumable aerosol-heating simulation device, respectively.

When the resistance-absorbing adjustment assembly 10 is disposed in the airflow path, the first adjustment member 101 and the second adjustment member 102 are arranged along the extending direction of the airflow path, the first adjustment member 101 has a side surface facing the second adjustment member 102, and the air passage 103 passes through the surface. The air flow passes through the first regulating element 101 and the second regulating element 102 in sequence while circulating in the air flow passage, or passes through the second regulating element 102 and the first regulating element 101 in sequence.

The number of the air passages 103 may be one or more, and the shape of the air passages 103 may be any shape such as a circle, an ellipse, a kidney, a square, a triangle, a fan, etc. In one possible implementation, the cross-sectional area of the airway 103 is less than or equal to the cross-sectional area of the airflow channel at the location. The air flow in the air flow channel is controlled by the suction resistance adjusting component 10, the cross-sectional area of the air flow channel can be designed to be larger, the process requirement is reduced, and the unsmooth air flow caused by the too small cross-sectional area of the air flow channel can be avoided.

The manner of movement of the second adjustment element 102 relative to the first adjustment element 101 may be sliding or rotating. The trajectory of the sliding movement of the second adjustment element 102 with respect to the first adjustment element 101 may be a straight line or a curved line.

Fig. 3 and 4 show a structure in which the second adjusting element 102 rotates relative to the first adjusting element 101, and referring to fig. 3 and 4, the resistance absorbing adjusting assembly 10 includes the first adjusting element 101, the second adjusting element 102 and the shaft 105, the first adjusting element 101 and the second adjusting element 102 are overlapped and attached to each other along the length direction of the shaft 105, one of the first adjusting element 101 or the second adjusting element 102 is fixedly connected with one end of the shaft 105, and the other is sleeved on the shaft 105, so that rotational connection between the two is realized. It should be noted that although in the designs of fig. 3 and 4 a physical axis is provided between the first adjustment element 101 and the second adjustment element 102, in this solution the physical axis is not mandatory. In some embodiments, a convex edge may be provided at the edge of the first adjusting element 101 and/or the second adjusting element 102, and then the first adjusting element 101 is sleeved with the second adjusting element 102, so as to achieve the effect that one element rotates in the other element.

Preferably, the first adjusting element 101 and the second adjusting element 102 rotate relatively to form an overflow hole with the same air flow, the area of the overflow hole changes along with the rotation, and the cross section area of the air passage 103 is larger than the maximum area of the overflow hole, so that the main pressure drop of the air flow channel is controlled by the rotating structure.

The shapes of the first adjusting element 101 and the second adjusting element 102 may be circular, square, fan-shaped, and other shaped, which is not limited in this embodiment. The air duct 103 on the first adjusting element 101 may be defined by the outer contour of the first adjusting element 101 or by a through hole penetrating the first adjusting element 101. The second adjusting element 102 is provided with a hollow part 104, and the hollow part 104 is communicated with the air duct 103 to allow air flow to pass through. The number of the hollowed-out parts 104 can be one or more, and the shape of the hollowed-out parts 104 can be any shape such as a circle, an ellipse, a waist, a square, a triangle, a fan and the like. Likewise, the air passage 103 on the second adjusting element 102 may be defined by the outer contour of the second adjusting element 102 or by a through hole penetrating the second adjusting element 102.

Fig. 5 shows a structure of the resistance-absorbing adjusting assembly 10, referring to fig. 5, the first adjusting element 101 and the second adjusting element 102 are fan-shaped, the outer contour of the first adjusting element 101 defines the air passage 103, and the outer contour of the second adjusting element 102 defines the hollow portion 104.
