[0067] Aerosol generating materials are materials that can generate aerosols, for example, when heated, irradiated or energized in any other way. Aerosol generating materials can be, for example, in solid, liquid or gel form, which may or may not contain active substances and / or fragrances. In some embodiments, the aerosol generating material may include an "amorphous solid", which may alternatively be referred to as a "whole solid" (i.e., non-fibrous).

In some alternative embodiments, the susceptor is on one or either side of the material.

[0072] A consumable is an article comprising or consisting of an aerosol generating material, some or all of which is intended to be consumed by a user during use. A consumable may include one or more other components, such as an aerosol generating material storage area, an aerosol generating material delivery component, an aerosol generating area, a housing, a wrapper, a mouthpiece, a filter and / or an aerosol modifier. A consumable may also include an aerosol generator, such as a heater, which releases heat during use to cause the aerosol generating material to generate an aerosol. The heater may, for example, include a combustible material, a material that can be heated by electrical conduction, or a susceptor.

[0073] A susceptor is a material that can be heated by being penetrated with a varying magnetic field (e.g., an alternating magnetic field). The susceptor can be a conductive material such that its penetration by the varying magnetic field results in inductive heating of the heated material. The heated material can be a magnetic material such that its penetration by the varying magnetic field results in hysteresis heating of the heated material. The susceptor can be both conductive and magnetic such that the susceptor can be heated by both heating mechanisms. In this article, a device configured to generate a varying magnetic field is referred to as a magnetic field generator.

[0074] Aerosol modifiers are substances typically located downstream of an aerosol generation region that are configured to modify the generated aerosol, for example by changing the taste, flavor, acidity, or another characteristic of the aerosol. The aerosol modifier may be disposed in an aerosol modifier release component that is operable to selectively release the aerosol modifier. For example, the aerosol modifier may be an additive or an adsorbent. For example, the aerosol modifier may include one or more of a flavoring, a coloring agent, water, and a carbon adsorbent. For example, the aerosol modifier may be a solid, a liquid, or a gel. The aerosol modifier may be in powder, string, or particle form. The aerosol modifier may be free of filter material.

[0075] An aerosol generator is a device configured to cause an aerosol to be generated from an aerosol generating material. In some embodiments, the aerosol generator is a heater configured to subject the aerosol generating material to thermal energy so as 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 an aerosol to be generated from the aerosol generating material without heating. For example, the aerosol generator can be configured to subject the aerosol generating material to one or more of vibration, increased pressure, or electrostatic energy.

[0076] The present disclosure relates to an aerosol supply system (which may also be referred to as a vapor supply system), such as a sprayer or an electronic cigarette. In the following description, the term "electronic cigarette" or "electronic cigarette" may sometimes be used, but it will be understood that this term can be used interchangeably with aerosol supply system / device and electronic aerosol supply system / device. In addition, as is common in the art, the terms "aerosol" and "vapor" and related terms such as "evaporation", "aerosolization" and "aerosolization" are often used interchangeably.

[0077] Aerosol supply systems (electronic cigarettes) typically (although not always) include modular components, which include a reusable device part and a replaceable (disposable / consumable) cartridge part. Typically, the replaceable cartridge part will include an aerosol generating material and a vaporizer (which can be collectively referred to as an "atomizer"), and the reusable device part will include a power source (e.g., a rechargeable power source) and a control circuit. It will be understood that these different parts may include additional elements depending on the function. For example, the reusable device part will typically include a user interface for receiving user input and displaying operating status features, and the replaceable cartridge device part includes a temperature sensor for helping to control the temperature in some cases. The cartridge is electrically and mechanically connected to the control unit for use, for example, using a thread, a bayonet, or a magnetic connection with appropriately arranged electrical contacts. When the aerosol generating material in the cartridge is exhausted, or when the user wishes to switch to a different cartridge with a different aerosol generating material, the cartridge can be removed from the reusable part and the replacement cartridge is attached to its appropriate position. Systems and devices conforming to this type of two-piece modular configuration may generally be referred to as two-piece systems / devices.

[0078] 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 using a disposable cartridge. However, it will be understood that the basic principles described herein may be equally applicable to different configurations, such as a one-piece system or a modular system including more than two components, a refillable device and single-use disposables, and other overall shapes, such as high-performance devices based on so-called box-shaped models that typically have a box shape. More generally, it will be understood that certain embodiments of the present disclosure are based on an aerosol supply system that is operationally configured to provide functionality according to the principles described herein, and that the structural aspects of the system configured to provide functionality according to certain embodiments of the present disclosure are not primarily important.

[0079] The present embodiment provides a heating component for an aerosol supply device, which includes a shell 100 and a heating tube 200. The shell 100 has a accommodating cavity 107, an opening 108 connected to the accommodating cavity 107, and an air inlet 109. The outer surface of the shell 100 is formed with a plurality of protrusions 102 for setting coils, and the shell 100 is integrally formed; the heating tube 200 is accommodated in the accommodating cavity 107, and a gap 300 is formed between the inner wall of the shell 100 and the outer wall of the heating tube 200.

[0080] The housing 100 includes a first housing 101 and a second housing 106 formed in the first housing 101, a receiving cavity 107 is provided in the second housing 106, the inner surface of the second housing 106 constitutes the inner wall of the housing 100, and the outer surface of the first housing 101 is formed with a plurality of protrusions 102 for setting the coil. In some embodiments, the material of the first housing 101 is different from the material of the second housing 106, and the first housing 101 and the second housing 106 are formed by a two-color injection molding process. The first housing 101 is hard plastic, and the second housing 106 is soft rubber. Exemplarily, the first housing 101 is PEEK; the second housing 106 is silicone. In other embodiments, the first housing 101 and the second housing 106 are injection molded with the same material, which requires that the materials used for the first housing 101 and the second housing 106 have both soft and deformable characteristics and certain supporting strength. Exemplarily, the materials of the first housing 101 and the second housing 106 can be silicone with slightly higher hardness.

[0081] In a possible implementation, a limiting assembly is provided on the inner wall of the second shell 106, and the limiting assembly is configured to limit the heating tube 200 from escaping from the accommodating cavity 107. In some embodiments, the limiting assembly includes a first limiting member 110 located at the upper portion of the second shell 106, and the first limiting member 110 abuts against the top of the heating tube 200. In other embodiments, the limiting assembly includes a first limiting member 110 and a second limiting member 111, the first limiting member 110 is provided at the upper portion of the second shell 106, the second limiting member 111 is provided at the lower portion of the second shell 106, the top of the heating tube 200 abuts against the first limiting member 110, and the outer peripheral wall of the heating tube 200 abuts against the second limiting member 111. Exemplarily, the first limiting member 110 may be a plurality of protrusions provided around the inner wall of the accommodating cavity 107, and the second limiting member 111 may be an annular protrusion surrounding the inner wall of the accommodating cavity 107.

[0082] See also Figure 2 and Figure 4The heating tube 200 is provided with a heating cavity 201, and the top of the heating tube 200 is provided with a nozzle 202, which connects the heating cavity 201 with the accommodating cavity 107, and the nozzle 202 is provided with an outer edge 203 that turns toward the outer periphery of the heating tube 200. When the heating tube 200 is accommodated in the accommodating cavity 107, the outer edge 203 at the nozzle 202 is located between the inner wall of the accommodating cavity 107 and the outer wall of the heating tube 200, so as to keep the heating tube 200 at the center position of the accommodating cavity 107 as much as possible. At the same time, the outer edge 203 has a certain shielding effect on the gap 300 between the outer wall of the heating tube 200 and the inner wall of the accommodating cavity 107, which can prevent debris from falling into the accommodating cavity 107. In some embodiments, the outer edge 203 can also contact the inner wall of the accommodating cavity 107.

[0083] See also Figure 1 , a side opening 103 is further provided on the first shell 101 at a position corresponding to the first stopper 110. The side opening 103 can provide space for the first stopper 110 to deform during the installation of the heating tube 200. Exemplarily, when the first shell 101 is made of hard plastic and the second shell 106 is made of soft rubber, the second shell 106 can be deformed, and the first shell 101 cannot be deformed. Since the heating tube 200 has an outer edge 203 and the inner wall of the second shell 106 has a first stopper 110, when the heating tube 200 is inserted into the accommodating cavity 107, the outer edge 203 must squeeze the first stopper 110 at a certain time point, so that the first stopper 110 deforms outward to enter or protrude from the side opening 103. When the heating tube 200 is installed in place, the nozzle 202 at the top of the heating tube 200 is lower than the first stopper 110. At this time, the outer edge 203 releases the squeezing of the first stopper 110, so that the first stopper 110 is reset. The height of the first limiting member 110 protruding from the inner wall of the second shell 106 is greater than the distance between the outer edge 203 and the inner wall of the second shell 106, and is less than the distance between the inner wall of the second shell 106 and the outer wall of the heating tube 200. In this way, the first limiting member 110 can limit the upper end of the heating tube 200 after being reset, and will not interfere with the aerosol generating product entering or pulling out of the heating tube 200.

[0084] In a possible implementation, a heat insulating portion is formed between the outer wall of the heating tube 200 and the inner wall of the second shell 106. In some embodiments, the air inlet 109 is located at the bottom of the second shell 106, the second stopper 111 seals the bottom outlet of the gap 300, the outer edge 203 of the heating tube 200 at least partially covers the top outlet of the gap 300, and the gap 300 constitutes the heat insulating portion. In some embodiments, a heat insulating material may be further provided between the inner wall of the heating chamber 201 and the outer wall of the heating tube 200, and the heat insulating material constitutes the heat insulating portion, and the heat insulating material may include aerogel, paper, plastic, or a composite material thereof.

[0085] See also Figure 4 The inner wall of the second shell 106 is further provided with a clamp 112, and the clamp 112 is configured to restrict the aerosol generating product from escaping from the heating tube 200. The clamp 112 is provided at the top of the second shell 106 and above the heating tube 200, and is used to abut against the outer wall of the aerosol generating product when the aerosol generating product is received in the heating tube 200. In some embodiments, the clamping member 112 can be configured as a protrusion protruding from the inner wall of the second shell 106 toward the center of the second shell 106. When the aerosol generating product enters the heating tube 200, the protruding top surface of the protrusion abuts against the outer wall of the aerosol generating product, thereby retaining the aerosol generating product in the heating tube 200. At the same time, the protruding top surface of the protrusion can be set as a point, a line or a smaller plane, or a point, a line or a smaller plane structure can be set on the top surface of the protrusion, so that a smaller contact area is maintained between the outer wall of the aerosol generating product and the protrusion, which can prevent the aerosol generating product from easily falling out, and reduce the friction between the protrusion and the outer wall of the aerosol generating product, so that the aerosol generating product can be easily pulled out after the inhalation is completed.

[0086] In a possible implementation, the heating assembly further includes a temperature detection element 104, and the temperature detection element 104 is disposed on the outer peripheral wall of the first shell 101. In some embodiments, a groove 105 is provided on the outer peripheral wall of the first shell 101 at a position corresponding to the position of the heating tube 200, and the temperature detection element 104 is installed in the groove 105. Exemplarily, the temperature detection element 104 can be adhered to the groove 105. Providing the groove 105 on the outer peripheral wall of the first shell 101 and installing the temperature detection element 104 in the groove 105 can make the temperature detection element 104 closer to the heating tube 200, thereby improving the accuracy of temperature detection. At the same time, the temperature detection element 104 is disposed in the groove 105, which has high space utilization, does not increase the outer peripheral volume of the shell 100, and is conducive to the miniaturization of the device.

[0087] This embodiment provides an aerosol supply device, which includes the above-mentioned heating component for an aerosol supply device.

[0088] This embodiment provides an aerosol supply system, which includes an aerosol generating article and the above-mentioned aerosol supply device, wherein the aerosol generating article is removably arranged on the aerosol supply device.

[0089] The heating assembly disclosed in the present invention includes a shell 100 and a heating tube 200. The shell 100 constructs a housing cavity 107 for receiving an aerosol-generating product, an air circulation channel that runs through the shell 100, and a protruding structure for winding a coil. The heating tube 200 is arranged in the housing cavity 107. Since the shell 100 is integrally formed, the number of parts is small, the overall process is simple, and the cost can be controlled to a relatively low level. In addition, the one-piece shell 100 design avoids the problem of gaps between parts when multiple parts are assembled, which is conducive to reducing the overall size of the heating assembly. In addition, the heating tube 200 is connected to the air inlet 109 on the shell 100 to form an airway. The number of parts in the air flow path from air inlet to air outlet is small, and the airway sealing performance is good, which is conducive to ensuring the consistency of taste during the inhalation process.
