Description

Technical Field

[0001] The utility model relates to the field of aerosol supply, in particular to an aerosol supply device and a system. Background Art

[0002] The aerosol supply system includes an aerosol supply device and an aerosol generating product (such as a tobacco product). The aerosol generating product is inserted into the heating chamber of the aerosol supply device, and the aerosol generating product is heated by the aerosol supply device to obtain an aerosol. This heat-not-burn technology allows the aerosol generating product to release active ingredients in the carbonization stage before combustion, thereby minimizing the generation of tar and harmful substances.

[0003] The heating methods of aerosol supply devices are divided into external heating and internal heating. The internal heating method generally involves inserting a needle-type or sheet-type heating element into the matrix segment of the aerosol generating product to diffuse heat from the center of the aerosol generating product to the outside. The external heating method generally involves using a barrel-shaped heating element to surround the matrix segment of the aerosol generating product to diffuse heat from the outside of the aerosol generating product to the inside.

[0004] The external heating method does not require the heating element to be inserted into the aerosol generating product, making it easier to plug and unplug the product. However, due to the inconsistent specifications of aerosol generating products circulating on the market, the existing aerosol supply device cannot adapt to aerosol generating products of different specifications at the same time. At the same time, due to the manufacturing errors between the aerosol generating product and the heating chamber, if the diameter of the aerosol generating product is too small or the diameter of the heating chamber is too large, the aerosol generating product is easy to loosen and fall off when the user inhales. Utility Model Content

[0005] The present disclosure aims to solve at least one of the technical problems existing in the prior art. The present disclosure provides an aerosol supply device and system to at least solve the technical problem in the prior art that aerosol generating products are easily loosened and fall off when inserted into a heating chamber.

[0006] A first aspect of the present disclosure provides an aerosol supply device, comprising:

[0007] a heating element having a heating cavity for receiving an aerosol-generating article, the heating element being configured to heat the aerosol-generating article received in the heating cavity to generate an aerosol;

[0009] In one embodiment of the above aerosol supply device, a gap is formed between the aerosol generating article and the inner wall of the heating element for allowing air flow to flow along the circumferential direction and the longitudinal direction of the heating element.

[0010] In one embodiment of the above aerosol supply device, the raised structure is configured to make point contact with the aerosol-generating article received in the heating chamber.

[0011] In one embodiment of the above-mentioned aerosol supply device, each of the protrusions includes a first guide portion for guiding the aerosol generating product into the heating chamber, an abutment portion abutting the aerosol generating product, and a second guide portion for guiding the aerosol generating product to exit the heating chamber.

[0012] In one embodiment of the above aerosol supply device, the protrusion is configured to be tangential to an outer wall of the aerosol generating article received in the heating chamber.

[0013] In one embodiment of the above aerosol supply device, the protrusion is configured to press the aerosol generating article in a radial direction of the aerosol generating article.

[0014] In one embodiment of the above aerosol supply device, when the protrusion presses the aerosol generating product, the force exerted by the protrusion on the aerosol generating product is no greater than 2N.

[0015] In one embodiment of the above aerosol supply device, when the aerosol generating product exits the heating chamber along the length direction, the friction force between the protrusion and the aerosol generating product is 0.6N-1.5N.

[0016] In an embodiment of the above aerosol supply device, the protrusion is hemispherical.

[0017] In one embodiment of the above aerosol supply device, the height of the protrusion protruding from the inner wall of the heating element is 0.1 mm-0.3 mm.

[0018] In one embodiment of the above aerosol supply device, each of the protrusion assemblies includes 10 to 12 protrusions.

[0019] In one embodiment of the aerosol supply device, in the length direction of the heating element, the distance between two adjacent protrusion components is 3 mm-5 mm.

[0020] In one embodiment of the aerosol supply device, in the circumferential direction of the heating element, the distance between two adjacent protrusions is 3 mm-5 mm.

[0021] In one embodiment of the aerosol supply device, the surface area of ​​the protrusion is 0.1 mm 2 -0.4mm 2 .

[0022] In one embodiment of the above aerosol supply device, the ratio of the heated area of ​​the aerosol generating article received in the heating element to the surface area of ​​all protrusions on the heating element is 49:1-45:1.

[0023] In an embodiment of the above aerosol supply device, the protrusion structure and the heating element are integrally formed.

[0024] In one embodiment of the above aerosol supply device, the inner wall and / or outer wall of the heating element is a rough surface.

[0025] In one embodiment of the above aerosol supply device, the surface of the heating element is roughened by laser roughening or chemical etching.

[0026] In one embodiment of the above-mentioned aerosol supply device, the heating element has an insertion port for inserting the aerosol generating product, the insertion port is connected to the heating chamber, and a guide surface for guiding the aerosol generating product into the heating chamber is provided at the insertion port, and the heating element is constructed in a cylindrical shape.

[0028] The above one or more technical solutions disclosed in the present invention have at least one or more of the following beneficial effects:

[0029] The present invention provides a protrusion structure on the inner wall of the heating element, and the protrusion structure includes a plurality of protrusion components spaced apart along the length direction of the heating element, and each protrusion component includes a plurality of protrusions spaced apart along the circumference of the heating element. When the aerosol generating product is inserted into the heating element, the protrusions abut against the outer peripheral surface of the aerosol generating product to clamp and limit the product, thereby preventing the aerosol generating product from falling off.

[0030] Each protrusion on the protrusion structure is in contact with the aerosol generating product, and the heating element directly transfers heat to the aerosol generating product through the protrusions. The portion of the inner wall of the heating element that is not in direct contact with the aerosol generating product can bake the aerosol generating product, which can improve the heating efficiency of the heating element. In addition, since there are gaps between the protrusions, the air heated by the heating element can flow between the gaps, so that the air temperature between the inner wall of the heating element and the aerosol generating product tends to be consistent, ensuring that the aerosol generating product is heated evenly.

[0031] The protrusions of the protrusion structure are distributed evenly on the inner wall of the heating element, and the clamping force applied by each protrusion on the aerosol generating product is equivalent. In addition, since the contact area between the protrusion and the aerosol generating product is small and the friction is small, the aerosol generating product is not likely to be bent during the process of inserting or removing the aerosol generating product.

[0032] Processing the surface of the heating element into a rough surface can increase the resistance of the heating element and improve the heating efficiency. Compared with a heating element with a smooth surface, this improvement can save energy consumption of the aerosol supply device.

[0033] Additional aspects and advantages of the present invention will be given in part in the following description and in part will become apparent from the following description or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

In some embodiments, the carrier includes a susceptor. In some embodiments, the susceptor is embedded in the material. In some alternative embodiments, the susceptor is on one or either side of the material.

[0081] 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.

[0082] 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.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] 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.

[0087] 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.

[0088] As described in the background technology, when an aerosol generating product is received in an externally heated aerosol supply device, the product is prone to loosening and falling off. Although the prior art attempts to fix the aerosol generating product in the heating chamber by adding a fixing mechanism, this method requires the user to operate the fixing mechanism to clamp or loosen the aerosol supply product, which is cumbersome to operate and does not provide a good user experience. In addition, the additional installation of a fixing mechanism will also increase costs. To this end, the present disclosure provides an aerosol supply device and system, which can achieve clamping and fixing of the aerosol generating product by improving the structure of the heating element without adding new components and increasing the operating steps.

[0089] The structures of the aerosol supply device and the aerosol supply system of the present invention will be described in detail below by way of specific embodiments.

[0090] The aerosol supply device 10 includes a shell, a heating module and an energy supply module. The heating module and the energy supply module are arranged in the shell. The heating module includes a heating element. The heating element has a heating cavity for receiving the aerosol generating product 20. The energy supply module is electrically connected to the heating element. The heating element can generate heat when electricity is turned on, thereby heating the aerosol generating product 20 received in the heating cavity to generate an aerosol.

[0091] See also Figure 1 and Figure 2 The heating module includes a shell 100, a heating element 200 and a coil 300. The shell 100 is provided with a accommodating cavity 101. The top of the shell 100 has a receiving port 102 that penetrates the accommodating cavity 101. The heating element 200 is arranged in the accommodating cavity 101. The heating element 200 is provided with a heating cavity 201. The top of the heating element 200 is provided with a plug-in port 202, which penetrates the receiving port 102 and the heating cavity 201. The coil 300 is arranged around the heating element 200 and is located between the outer wall of the heating element 200 and the inner wall of the shell 100.

[0092] The aerosol generating product 20 can sequentially enter the heating chamber 201 through the receiving port 102 and the plug port 202. The heating element 200 is made of magnetic induction material. When the coil 300 is energized to generate an induced magnetic field, the heating element 200 located in the induced magnetic field heats up, thereby heating the aerosol generating product 20 received therein.

[0093] See also Figure 3 and Figure 4 The inner wall of the heating element 200 is provided with a protrusion 205 structure, which includes a plurality of protrusion 205 components spaced apart along the length direction of the heating element 200 , and each of the protrusion 205 components includes a plurality of protrusions 205 spaced apart along the circumference of the heating element 200 .

[0094] In a possible implementation, the heating element 200 is cylindrical, and the protrusion 205 structure is arranged on the inner wall of the cylindrical heating element 200. A guide surface 204 is also provided at the plug-in port 202 at the top of the cylindrical heating element 200, which is used to guide the aerosol generating product 20 into the heating chamber 201. Each protrusion 205 assembly includes 10 to 12 protrusions 205. In the length direction of the heating element 200, the distance between two adjacent protrusion 205 assemblies is 3mm-5mm. In the circumferential direction of the heating element 200, the distance between two adjacent protrusions 205 is 3mm-5mm. The protrusion 205 structure can be integrally formed with the heating element 200. For example, the protrusion 205 can be constructed on the inner surface of the heating element 200 by a stamping process. The shape and size of each protrusion 205 in the protrusion 205 structure can be the same or different.

[0095] In this embodiment, a plurality of protrusions 205 are provided on the inner wall of the heating element 200. When the aerosol generating product 20 is received in the heating chamber 201, these protrusions 205 abut against the outer wall of the aerosol generating product 20. Under the action of the friction between the two, the aerosol generating product 20 will not be removed from the heating element 200 without a pulling force. There are multiple contact points between the aerosol generating product 20 and the heating element 200, and the heat generated by the heating element 200 can be quickly transferred to the aerosol generating product 20. Since these protrusions 205 are almost all over the heating element 200, the heating element 200 can evenly dissipate heat, ensuring that each area of ​​the aerosol generating product 20 receives similar amounts of heat, thereby achieving even heating.

[0096] When the aerosol generating product 20 is received in the heating chamber 201, a gap 103 is formed between the aerosol generating product 20 and the inner wall of the heating element 200, and the gap 103 extends along the circumference and length direction of the heating element 200, and air can flow freely in the gap 103. The heating element 200 heats the air in the gap 103, so that the part of the aerosol generating product 20 located in the heating chamber 201 is evenly wrapped by the hot air, and the aerosol generating product 20 is heated more evenly. Preferably, the height of the protrusion 205 protruding from the inner wall of the heating element 200 is 0.1mm-0.3mm, and the width of the gap 103 is consistent with the height of the protrusion 205 protruding from the inner wall of the heating element 200.

[0097] The shape of the protrusion 205 may be any shape, but in order to prevent the protrusion 205 from piercing the packaging material of the aerosol generating article 20, the protrusion 205 is provided with a soft guiding surface at least in the insertion direction and the removal direction of the aerosol generating article 20. The guiding surface may be, for example, an inclined surface or a curved surface. Depending on the shape of the protrusion 205, the protrusion 205 and the aerosol generating article 20 may be in surface contact, point contact, or line contact.

[0098] See also Figure 6and Figure 7 The inner wall of the heating element 200 is provided with a plurality of protrusions 205 at intervals. When the aerosol generating product 20 is received in the heating chamber 201, the protrusions 205 are in point contact with the aerosol generating product 20. Figure 5 Each of the protrusions 205 includes a first guide portion 206, a second guide portion 207 and an abutment portion 208, wherein the first guide portion 206 is used to guide the aerosol generating article 20 to enter the heating chamber 201, the abutment portion 208 is used to abut the aerosol generating article 20, and the second guide portion 207 is used to guide the aerosol generating article 20 to exit the heating chamber 201. Preferably, the shape of the protrusion 205 is hemispherical.

[0099] In a possible implementation, when the aerosol generating product 20 is received in the heating, the protrusion 205 is tangent to the outer wall of the aerosol generating product 20. The protrusion 205 presses the aerosol generating product 20 in the radial direction of the aerosol generating product 20. Wherein, when the protrusion 205 presses the aerosol generating product 20, the force applied by the protrusion 205 on the aerosol generating product 20 is not greater than 2N. In the process of the aerosol generating product 20 exiting the heating chamber 201 along the length direction, the friction force between the protrusion 205 and the aerosol generating product 20 is 0.6N to 1.5N. The protrusion 205 abuts against the aerosol generating product 20 and applies force to it, which can confine the aerosol generating product 20 in the heating chamber 201 and prevent it from falling off without being pulled out. After the user has finished inhaling, when holding the portion of the aerosol generating product 20 exposed outside the aerosol supply device 10 and pulling it outward, only a small pulling force is required to take out the aerosol generating product 20, so the user can operate easily and the product is not likely to break.

[0100] The surface area of ​​a single protrusion 205 is 0.1 mm 2 -0.4mm 2 The ratio of the heated area of ​​the aerosol generating article 20 to the surface area of ​​all the protrusions 205 is 49:1-45:1. Exemplarily, the surface area of ​​each protrusion 205 is 0.2 mm 2 , the total surface area of ​​all protrusions on the heating element is 16mm 2 The heating area of ​​the aerosol generating article is 787.1 mm 2, the ratio of the heating area of ​​the aerosol generating product to the sum of the surface areas of all protrusions is 787.1:16≈49:1. Among them, the heating area of ​​the aerosol generating product refers to the surface area of ​​the part of the aerosol generating product that enters the heating chamber 201, and this part can be heated by the heating element 200. In this embodiment, by providing a protrusion 205 structure on the inner wall of the heating element 200, the surface area of ​​the inner wall of the heating element 200 is increased, so that the heating element 200 can release more heat. Although the protrusions 205 are distributed all over the inner wall of the heating element 200, the contact area between a single protrusion 205 and the aerosol generating product 20 is not large, so that the force applied by each protrusion 205 to the aerosol generating product 20 is small, and the force required to plug and unplug the aerosol generating product 20 is also small. At the same time, more air circulation space is also constructed between the aerosol generating product 20 and the inner wall of the heating element 200.

[0101] In a possible implementation, the heating element 200 is further provided with an air inlet 203, and the position of the air inlet 203 matches the air flow channel of the aerosol supply device 10. If the air flow channel of the aerosol supply device 10 runs through the accommodating chamber 101 from bottom to top, the air inlet 203 is provided at the bottom of the heating element 200 to allow fresh air to enter the heating chamber 201 from the bottom of the heating element 200 through the air inlet 203. If the air flow channel of the aerosol supply device 10 is connected to the accommodating chamber 101 from the side, the air inlet 203 can be provided on the side wall of the heating element 200 to allow fresh air to enter the heating chamber 201 through the side wall of the heating element 200.

[0102] Figure 3 and Figure 4 A structure of the heating element 200 is shown in FIG. Figure 3 and Figure 4 The heating element 200 has a heating cavity 201 inside, a plug-in port 202 at the top, an air inlet 203 at the bottom, and a protrusion 205 protruding toward the heating cavity 201 on the inner wall of the heating element 200. The entire heating element 200 is 34 mm long. Starting from the bottom of the heating element 200, a protrusion 205 assembly is provided every 4 mm. Each protrusion 205 assembly includes 10 to 12 protrusions 205 of the same size and shape distributed along the circumference of the heating element 200. The height of each protrusion 205 protruding from the inner wall of the heating element 200 is 0.2 mm. When the aerosol generating product 20 is inserted into the heating cavity 201, the diameter of the aerosol generating product 20 is just tangent to the protrusion 205. The force applied by the protrusion 205 to the aerosol generating product 20 is within 2N, and the force required to pull out the aerosol generating product 20 is 0.6N to 1.5N.

[0103] The surface of the heating element may be a smooth surface or a rough surface, and the protruding structure is arranged on the smooth surface or the rough surface.

[0104] In a possible implementation, the inner wall or the outer wall of the heating element is a rough surface, or both the inner wall and the outer wall of the heating element are rough surfaces. Specifically, the surface of the heating element can be roughened by a laser roughening treatment method or a chemical etching process. Exemplarily, the plate for preparing the heating element can be laser roughened in advance to obtain a plate with a rough surface, and then a protrusion is formed on the surface of the plate by a stamping process, and then the plate is rolled into a heating element. Exemplarily, a protrusion can be formed on the surface of the plate by a stamping process, and then the plate is rolled into a cylindrical shape, and then the cylindrical heating element is chemically etched to roughen the surface of the heating element.

[0105] When the surface of the heating element is roughened, the resistance of the heating element will increase due to the skin effect, thereby improving the heating efficiency. Compared with a heating element with a smooth surface, the current of the heating element with a rough surface is smaller than that of the heating element with a smooth surface to reach the same heating temperature, thereby reducing energy consumption, making the battery life of the aerosol supply device longer and increasing durability.

[0106] This embodiment further provides an aerosol supply system, which includes an aerosol supply device 10 and an aerosol generating product 20, wherein the aerosol generating product 20 is removably disposed in the aerosol supply device 10. The structure of the aerosol supply device 10 is as described in the above embodiment, and will not be described in detail here.

[0107] like Figure 6 and Figure 7As shown, the matrix section of the aerosol generating product 20 sequentially passes through the receiving port 102 at the top of the housing 100 and the plug port 202 at the top of the heating element 200, and enters the heating chamber 201. At this time, the protrusion 205 on the inner wall of the heating element 200 abuts against the outer wall of the aerosol generating product 20, and the aerosol generating product 20 is confined in the heating chamber 201 to prevent the product from slipping out. After the coil 300 is energized, the heating element 200 generates heat, and part of the heat is directly transferred to the aerosol generating product 20 through the protrusion 205, and part of the heat heats the air between the aerosol generating product 20 and the inner wall of the heating element 200. The heated air circulates between the protrusions 205, so that the temperature of the air surrounding the outer periphery of the aerosol generating product 20 tends to be consistent. Surrounded by the hot air, the part of the aerosol generating product 20 that is not in contact with the protrusion 205 is indirectly heated. Since the protrusions 205 on the heating element 200 are evenly distributed, and the hot air flows smoothly in the gap 103 between the aerosol generating product 20 and the inner wall of the heating element, the matrix section of the aerosol generating product 20 is evenly heated, which can improve the heating efficiency and the user's puffing experience. After the puffing is finished, the user can hold the aerosol generating product 20 to pull it out. Since there are multiple points of contact between the heating element 200 and the aerosol generating product 20, the force applied by the protrusions 205 to any area of ​​the aerosol generating product 20 is not large, so it is not easy to break the aerosol generating product 20 when pulling it out.
