Technical Field

The invention relates to the field of aerosol supply, in particular to an aerosol supply system.

Background

An aerosol supply system refers to a system in which an aerosol-generating material is contained, and an aerosol is generated by heating, rather than burning, the aerosol-generating material (e.g. tobacco) for inhalation by a user.

The aerosol supply system generally includes a housing, an atomizer disposed within the housing, a power source, and a controller. The atomizer comprises a heating element, and a power supply supplies power to the heating element under the control of the controller, and the heating element is electrified to generate heat so as to heat aerosol generating materials in the shell to generate aerosol.

The atomizer includes an atomizer support defining an atomizing chamber and a heating element disposed within the atomizing chamber. When the system is assembled, the leading-out pins of the heating element are electrically connected with the electrodes outside the atomizing cavity, and the electrodes are electrically connected with a power supply so as to realize the power supply of the power supply to the heating element. The connection of the pins of the heating element to the electrodes is currently performed by soldering. However, the welding is a complex process, which results in complex system assembly process, and the welding requires leading the pins out of the atomizing cavity, and the length of the pins is longer, so that certain size requirements are required for the pins and the electrodes to realize the stability of the welding, which results in larger overall volume of the system.

Accordingly, a new aerosol provision system is needed to address one or more of the above-described problems.

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.

As described in the background art, the connection between the pins and the electrodes of the current heating element is performed by welding, which causes the problems of complex assembly process, large system volume, and the like. Therefore, the embodiment of the invention creatively provides a novel aerosol supply system, wherein the atomizer bracket is provided with the limiting hole, and the welding-free connection of the heating element and the electrode is realized in the limiting hole, so that the complexity of an assembly process is reduced, and the volume of the system is reduced.

The structure of the aerosol provision system of the present invention will be described in detail by way of specific examples.

Referring to fig. 1-3, the aerosol provision system is an elongate structure extending along a longitudinal axis. The aerosol provision system comprises, in a height direction, opposite proximal and distal ends, and a housing 100 extending between the proximal and distal ends. The housing 100 is provided with a suction nozzle 101 at a proximal end, and the suction nozzle 101 is provided with an air outlet 102. The housing 100 is also provided with an air inlet 103. The air inlet 103 may be provided at the distal end as shown in fig. 2 and 3, or may be provided at other locations of the housing 100.

A receiving space and an air passage are formed in the housing 100, and a receiving chamber 200 for receiving an aerosol-generating material (e.g., tobacco tar), an atomizer 300, a power source (battery assembly) 400, and a controller (control circuit) 500 are provided in the receiving space. The receiving chamber 200, the atomizer 300, the controller 500, and the power supply 400 are arranged substantially along the height direction of the system. The power supply 400 is configured to supply power to the heat generating components in the atomizer 300 under the control of the controller 500. An atomizer chamber 310 for receiving a heat generating component is provided within the atomizer 300. The nebulization chamber 310 is in fluid communication with the receiving chamber 200, and aerosol-generating material in the receiving chamber 200 can enter the nebulization chamber 310 to be heated by the heat generating component.

The air inlet 103, the atomizing chamber 310 and the air outlet 102 communicate to form an air passage within the housing. When the user sucks, external air enters from the air inlet 103, and passes through the atomizing chamber 310 to take aerosol therein, and then flows out from the air outlet 102 to the user.

In one embodiment of the present invention, the system further comprises a first sealing cover 104 for sealing the air outlet 102 and a second sealing cover 105 for sealing the air inlet 103. The first sealing cap 104 and the second sealing cap 105 may be capped to ensure safety and sanitation when the aerosol supply system is not in use.

Referring to fig. 1 to 3, the housing 100 includes two separate parts, an upper housing 110 having a suction nozzle 101, and a lower housing 120, respectively. The upper case 110 is provided therein with a receiving chamber 200 and an atomizer 300, and the lower case 120 is provided therein with a power supply 400 and a controller 500. The lower end portion of the upper housing 110 is located within the lower housing 120. In an alternative embodiment, the upper case 110 and the lower case 120 are not substantially overlapped in the height direction of the system, and the lower end of the upper case 110 is connected with the upper end of the lower case 120 to form the case 100.

In one embodiment, the upper housing 110 and the lower housing 120 are configured for removable connection such that the aerosol generating material or the atomizer 300, etc. within the upper housing 110 may be replaced or such that the atomizer 300 may be connected to a different power source 400. It will be appreciated that in other embodiments, the upper housing 110 and the lower housing 120 are permanently connected once assembled.

In alternative embodiments, the housing 100 may also be configured as an integrally formed, independent structure, unlike the structure shown in fig. 1-3, in which the upper and lower housings are independently provided. From the perspective of internal part assembly and reusability, the arrangement mode of the upper shell and the lower shell is more advantageous than that of an integrally formed shell.

In other embodiments of the present invention, the aerosol supply system may be a cartridge structure, and the atomizer 300 and the power supply 400 may be arranged in a lateral direction extending from side to side. The housing 100 may be configured as an integrally formed box housing. It may be configured to include two housings disposed in a left and right connection, and one housing is provided with the housing chamber 200, the atomizer 300, and the other housing is provided with the power supply 400 and the controller 500. The left and right housings may be provided in detachable connection. Of course, in alternative embodiments, the left and right housings are permanently connected once assembled.

The suction nozzle 101 may be integrally formed with the housing 100 or may be removably separated from the housing 100. The detachable nozzle 101 facilitates cleaning of the nozzle 101. Furthermore, the provision of a detachable mouthpiece 101 may facilitate access to the interior of the housing 100 to facilitate replacement of aerosol-generating material within the housing 100.

The power supply 400 is configured to provide power to the nebulizer 300, which may be a battery assembly in particular. In other examples, the battery may be replaced by a portable power source (e.g., a capacitive power store such as a supercapacitor or ultracapacitor), a mechanical power source (a mechanical power spring or generator), or an alternative chemical energy source (e.g., a fuel cell).

The aerosol-generating material may be solid, powder or liquid. In one embodiment of the invention, the receiving chamber 200 is for receiving a liquid aerosol-generating material. As shown in fig. 2-3, the receiving chamber 200 includes an outer wall, and the outer wall of the receiving chamber 200 may be integrally formed with the housing 100, i.e., the outer wall forms a part of the housing 100. The outer wall and the housing 100 may also be separate two parts, the housing 100 being provided outside the outer wall. The outer wall cover is provided at least partially outside the atomizer 300, and the accommodating chamber 200 is formed by surrounding the outer wall and a part of the surface of the atomizer 300 together.

To achieve aerosolization, the liquid aerosol-generating material in the receiving chamber 200 needs to be delivered into the aerosolization chamber 310. To this end the system further comprises a liquid inlet structure 600 for delivering liquid aerosol-generating material from the holding chamber 200 to the nebulizing chamber 310.

Fig. 4 is a partial block diagram of an aerosol provision system provided by an embodiment of the present invention, in which a liquid inlet structure 600 is shown. Referring to fig. 2-4, the liquid inlet structure 600 provided in the embodiment of the present invention includes a support frame 610, a liquid inlet channel 620, a first liquid inlet 630, and a ventilation hole 640, where the liquid inlet channel 620 is communicated with the accommodating chamber 200 and the atomizing chamber 310.

The supporting frame 610 is formed with a liquid guiding groove 622 and an annular groove 621 which are communicated with each other. It will be appreciated that an annular recess 621 is provided in the upper surface of the support shelf 610, which upper surface is provided facing the receiving chamber 200. The sump 622 may be made up of several parts, and at least part of the sump 622 extends in the longitudinal direction of the aerosol provision system, and the annular recess 621 extends in the transverse direction of the aerosol provision system. The liquid guiding groove 622 and the annular groove 621 are formed as the liquid inlet channel 620. A portion of the liquid guide channel 622 extending in the longitudinal direction of the aerosol supply system is arranged adjacent to the nebulization chamber 310 in the transverse direction of the system. The liquid guiding groove 622 has a first sidewall 6211 surrounding one side of the atomizing chamber 310, and the first liquid inlet 630 and the air outlet 640 are disposed on the first sidewall 6211 and penetrate through the first sidewall 6211. The first fluid inlet 630 and the vent 640 both communicate the fluid guide slot 622 with the nebulization chamber 310. The aerosol-generating material in the receiving chamber 200 sequentially passes through the liquid guide groove 622 and the first liquid inlet 630 into the atomizing chamber 310. The ventilation aperture 640 is configured to communicate with the external atmosphere of the aerosol supply system. Thus, when the internal pressure of the receiving chamber 200 becomes smaller as the aerosol-generating material is consumed during use of the system, the external atmosphere may enter the nebulizing chamber 310 from the outside due to the pressure difference, then enter the liquid guide groove 622 through the air vent hole 640, and then enter the receiving chamber 200 through the liquid guide groove 622 to maintain the hydraulic balance of the receiving chamber 200.

In the preferred embodiment of the present invention, the ventilation hole 640 is disposed above the first liquid inlet hole 630 along the height direction of the system, so that bubbles generated in the aerosol-generating material are not easily stuck at the first liquid inlet hole 630, and the first liquid inlet hole 630 is prevented from being blocked, so that the aerosol-generating material can smoothly enter the atomizing chamber 310 from the accommodating chamber 200, and the use of the system is prevented from being affected.

Further, the system also includes a second airway seal 700 for sealing between the support frame 610 and the receiving chamber 200. In particular, the shape and size of the second air passage sealing member 700 are adapted to the size and shape of the end of the supporting frame 610 near the receiving chamber 200, and are not particularly limited herein. The outer wall of the receiving chamber 200 is covered on the outer periphery of the second air passage sealing member 700, and the portion of the outer wall contacting the second air passage sealing member 700 is interference fitted. In this way, leakage of aerosol-generating material in the receiving chamber 200, contamination of other components of the battery assembly in the aerosol-supply system, etc. may be avoided. Meanwhile, in order to achieve fluid communication between the receiving chamber 200 and the liquid guiding groove 622, a second liquid inlet hole 710 is formed in the second air passage sealing member 700, so that the aerosol generating material in the receiving chamber 200 enters the liquid guiding groove 622 through the second liquid inlet hole 710.
