Description

Technical Field

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

[0002] In the e-cigarette industry, the aerosol supply system is configured to generate an aerosol-generating matrix (e.g., a matrix containing tobacco or tobacco leaves) into an aerosol for inhalation by the user. The existing aerosol supply system uses resistance heating technology. The surface area and length of each turn of the heating coil used for resistance heating are the same, and the resistance is uniform. Since the heating coil at the bottom of the heating component is the same as the upper end, the heating coils at the bottom and upper ends will generate the same amount of heat in the heating component, and the bottom end is usually used for installation in the aerosol supply system, so that the heat at the bottom of the heating component is easily transferred to the aerosol supply system, thereby making the hardware surface temperature of the aerosol supply system higher, which has an adverse effect on the normal use of the system.

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.

[0084] 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.

[0085] 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.

[0086] 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.

[0087] 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.

[0088] 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.

[0089] 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.

[0090] As described in the background technology, since the resistance of the heating coil of the resistance heating is uniform and the heat generated is the same, the temperature at the bottom of the heating component will be too high, which will be transferred to the aerosol supply system, making its surface temperature high, which is not conducive to the normal use and life of the system; at the same time, since the condensed water on the top of the aerosol generating material will flow downward during the heating process, if the temperature at the bottom is too high, condensate will gradually form, and excessive condensate will affect the normal use of the heating component. For example, the aerosol generating material replaced later cannot be fully inserted and used. Based on this, the utility model proposes a heating component for an aerosol supply system to solve the technical problem of how to reduce the heat transferred from the heating component to the aerosol supply system.

[0091] See attached Figure 1 , Figure 1 A heating component of an aerosol supply system is shown. The heating component 10 is configured to be at least partially inserted into an aerosol generating material for heating. The heating component 10 includes a heating coil 100 and a coil support 200 for supporting the heating coil 100. The coil support 200 has a support portion 201 extending into the heating coil 100, and a mounting portion 202 extending out of the heating coil 100 and having a heat-insulating property. The heating component 10 is installed in the aerosol supply system through the mounting portion 202. The utility model aims to reduce the heat conducted from the heating coil 100 to the aerosol supply system by arranging the mounting portion 202 extending out of the heating coil 100 and having a heat-insulating property on the coil support 200, thereby helping to reduce the temperature of the system surface and reducing the impact on the normal use of the system. At the same time, since the coil support 200 has the mounting portion 202 with a heat-insulating property, the bottom temperature of the entire heating component 10 is low, which can effectively reduce the condensation of the aerosol generating material inserted therein.

[0092] It should be noted that, in order to illustrate the present technical solution, Figure 1 The schematic diagram only shows a part of the structure of the heating component 10, and is not intended to convey the specific positions and fixed structural modes of various components. For example, the shape and size of the mounting portion 202 can be set according to actual installation requirements to facilitate installation. It should also be understood that the heating component 10 also includes other components, such as Figure 1 The power line 101 shown in FIG. 1 may also include other Figure 1 The components shown in the figure, such as the protective housing, etc., are not limited to the shapes, positions and sizes shown in the figures.

[0093] In one embodiment, the bottom end of the coil support 200 extends outward to form a mounting portion 202. It should be understood that there is no specific limitation on the extension length and size thereof. It can be at the bottom of the coil support 200 and extend beyond the heating coil 100. It can have the same cross-sectional area as the support portion 201, or it can be as shown in FIG. Figure 1As shown, the cross-sectional area of ​​the contact surface between the mounting portion 202 and the supporting portion 201 is larger than the cross-sectional area of ​​the supporting portion 201 , which is more conducive to heat insulation and reduces the heat transferred to the surrounding of the mounting portion 202 .

[0094] In one embodiment, if Figure 1 As shown, the mounting portion 202 includes a protrusion 2021 for a snap-on system, or, as shown Figure 2 As shown, the mounting portion 202 includes a card slot 2022 for a card connection system. The protrusion 2021 and the card slot 2022 are used to facilitate installation in the aerosol supply system. The shape and size can be designed according to actual installation requirements without specific restrictions.

[0095] In one embodiment, if Figure 3 As shown, the coil support 200 also includes a receiving portion 203, which is arranged between the support portion 201 and the mounting portion 202. The receiving portion 203 increases the distance between the heating coil 100 and the mounting portion 202, improves the heat insulation effect, and further reduces the heat transferred from the mounting portion 202 to the system. Further, the receiving portion 203 is formed by extending outward from the circumference of the support portion 201, and the cross-sectional area of ​​the contact surface between the receiving portion 203 and the support portion 201 can be greater than or equal to the cross-sectional area of ​​the support portion 201, and at the same time smaller than the area of ​​the mounting portion 202, so as to facilitate the winding of the heating coil 100 and the fixed installation of the entire coil support 200, and the area of ​​the receiving portion 203 and the mounting portion 202 is gradually increased compared with the support portion 201, which is more conducive to heat dissipation and heat insulation, and effectively reduces the heat transferred to the system.

[0096] Based on the above embodiment, at least one of the support part 201, the receiving part 203 and the mounting part 202 contains a high temperature resistant non-conductive material, which has the effect of insulating and cooling the heat generated by the heating coil 100. Preferably, the support part 201, the receiving part 203 and the mounting part 202 all contain high temperature resistant non-conductive materials, so that they have heat insulation properties, such as ceramics. Furthermore, the support part 201, the receiving part 203 and the mounting part 202 are an integrally formed structure, which can be an integrally formed ceramic tube, the upper part of which is used to support the heating coil 100, and at the same time, the lower part insulates the contact between the heating component 10 and the system to reduce the heat transferred to the system.

[0097] In one embodiment, if Figure 4 and Figure 5As shown, the heating component 10 also includes a heat-conductive shell 300, the support portion 201 and the heating coil 100 are arranged in the heat-conductive shell 300, the heat-conductive shell 300 abuts the receiving portion 203, the heat-conductive shell 300 is in direct contact with the aerosol generating material inserted into the system, and the heat generated by the heating coil 100 is transferred to the heat-conductive shell 300, thereby heating the aerosol generating material inserted into the system to generate an aerosol. Since the heat-conductive shell 300 is arranged corresponding to the support portion 201, it can fully conduct the heating of the aerosol generating material, and the receiving portion 203 and the mounting portion 202 can effectively insulate part of the heat-conductive shell 300, thereby reducing the heat conducted from the bottom of the heating component 10 to the outside of the system. It should be understood that the heat-conductive shell 300 can also directly abut on the mounting portion 202, and the mounting portion 202 can also reduce the heat conducted to the system. Furthermore, the thermal conductivity of the mounting portion 202 and / or the receiving portion 203 is smaller than the thermal conductivity of the thermally conductive shell 300, which is more conducive to reducing the heat transferred from the bottom of the heating component 10 to the system. For example, the mounting portion 202 and / or the receiving portion 203 are ceramic tubes, and the thermally conductive shell 300 can be a metal thermally conductive shell. The metal thermally conductive shell has a large thermal conductivity, a fast heat conduction speed, and a high amount of heat transferred, which can fully heat the aerosol generating material.

[0098] In a specific embodiment, the area of ​​the end surface of the receiving portion 203 close to the heat-conducting shell 300 is greater than or equal to the cross-sectional area of ​​the heat-conducting shell 300, thereby improving the heat insulation effect of the bottom of the heating component 10. Preferably, the area of ​​the end surface of the receiving portion 203 close to the heat-conducting shell 300 is completely equal to the cross-sectional area of ​​the heat-conducting shell 300, and the outer surfaces of the two are in contact. In this way, after the aerosol generating material is inserted into the system, it can directly abut against the mounting portion 202, and the outer peripheral surfaces of the heat-conducting shell 300 and the receiving portion 203 are in direct contact with the aerosol generating material, and the heat-conducting shell 300 can fully The aerosol generating material is heated, and the aerosol generating material inserted into the system obtains relatively less heat from the mounting portion 202 and the receiving portion 203. Therefore, the aerosol generating material corresponding to the receiving portion 203 close to the bottom of the heating component 10 will not be fully heated. When the condensed water generated by the aerosol generating material at the upper end of the heating component 10 flows downward after being heated, the aerosol generating material that is not fully heated plays a filtering role, thereby reducing the condensate, which is more conducive to the next replacement of the aerosol generating material, and no condensate will be left at the bottom of the heating component 10 to affect its service life. Further, refer to Figure 4 The receiving portion 203 includes a tubular receiving portion, and the heat-conducting housing 300 includes a tubular outer wall. The outer diameter of the tubular receiving portion is greater than or equal to the outer diameter of the tubular outer wall. The tubular design is more conducive to the insertion of the aerosol generating material, and the contact surface is fully heated. Figure 4 and Figure 5In the embodiment, the receiving portion 203 and the heat-conducting housing 300 are coaxially arranged and the outer walls are connected. After the aerosol generating material is inserted into the heating component 10, it can directly abut against the mounting portion 202. The receiving portion 203 and the mounting portion 202 both play a role of heat insulation. The aerosol generating material inserted into the receiving portion 203 can also play a filtering role due to insufficient heating, thereby reducing condensation. Further, as Figure 4 and Figure 5 The end of the heat-conducting housing 300 away from the receiving portion 203 is provided with a sharp tip, which is more conducive to the insertion and use of the aerosol generating material. It should be understood that the shape, size and length of the heat-conducting housing 300 can be adaptively set according to the aerosol supply system actually used and installed and the structure size of the heating coil 100 and the coil support 200, and the present invention does not limit it.

[0099] In a specific embodiment, the heat-conductive shell 300 is filled with an insulating high-temperature resistant material 400, such as a mixture of inorganic glue and glass powder, in order to fill the internal gap of the heating component 10. After the heating component 10 is assembled, it is filled in the gap between the heat-conductive shell 300 and the coil bracket 200 in a liquid state.

[0100] In one embodiment, reference Figure 3 The receiving portion 203 is provided with a first type of hole 2031 and a second type of hole 2032. The first type of hole 2031 is for the power line 101 connected to the heating coil 100 to pass through. The power line 101 is connected to the heating coil 100. When the system is powered on, the current flows from the power line 101 through the heating coil 100 to generate heat, and the heat is transferred to the heat-conducting shell 300 to heat the aerosol generating material. Preferably, the coil support 200 is a hollow tubular as a whole, that is, the support portion 201, the receiving portion 203 and the mounting portion 202 are all coaxially arranged tubular components. One end of the power line 101 passes through the receiving portion 203 from the first type of hole 2031 to connect to the heating coil 100 in the heat-conducting shell 300. The top of the heating coil 100 is connected to another power line 102. The power line 102 passes through the hollow part of the coil support 200, passes through the support portion 201, the receiving portion 203 and the mounting portion 202 in sequence, and is connected to the power supply equipment of the system to form a power-on circuit. The second type of holes 2032 are filled in the heat conducting housing 300 with Figure 5 The insulating high temperature resistant material 400 is shown. It should be understood that the number and position of the holes can be adjusted according to actual installation requirements without specific limitation.

[0101] Further, if Figure 6 As shown, the utility model provides an aerosol supply system.

[0102] a chamber 500 containing an aerosol generating material;

[0103] As described above, the heating component 10 is configured to heat the aerosol generating material to generate aerosol.

[0104] In one embodiment, if Figure 7 As shown, the aerosol supply system is also provided with a base 600 for installing the heating component 10, and the mounting portion 202 of the heating component 10 is installed in the base 600 and installed in the system through the base 600, which further reduces the heat transferred from the heating component 10 to the system housing, reduces damage to the system housing, and helps to reduce the surface temperature of the system. It should be understood that in the present invention, the heating component 10 is provided with a mounting portion 202 on the coil bracket 200 of the main body part, which directly reduces the heat conducted from the bottom from the "source" of heat generation, directly plays a protective role for other contact parts, and reduces the accumulation of condensate. The specific effect of the heat insulation structure can be found in the above-mentioned specific implementation method of the heating component, and the repeated parts will not be repeated. Compared with the heating component 10 being directly installed in the system through the base 600, it can not only improve the heat insulation effect, but also reduce the damage to the base 600, thereby increasing its service life.

[0105] In a specific embodiment, the mounting portion 202 and the base 600 can be mounted and connected by a mounting flange 601 to improve stability. The material of the mounting flange 601 can be a thermoplastic elastomer, which can keep the heating component 10 stable and have a certain shockproof effect. Furthermore, an elastic sealing ring 602 can be set around the base 600 at the connection between the base 600 and the system to improve stability and play a shockproof role.

[0106] It should be understood that the aerosol supply system may also include other components, such as Figure 6 The control element 700 shown in the figure is connected to control the heating coil 100 in the heating component 10, and the heating coil 100 generates heat when powered on to heat the aerosol generating material; the aerosol supply system also includes elements not shown in the figure, for example, a power supply for supplying power to the system, etc. The utility model does not limit the specific positions of the main components.

[0107] It is understood by those skilled in the art that each module in the system can be adaptively split or merged. Such splitting or merging of specific modules will not cause the technical solution to deviate from the principle of the present utility model, and therefore, the technical solutions after splitting or merging will fall within the protection scope of the present utility model.
