Description

heating device

The present disclosure relates to aerosol-generating products, heating devices, and heating elements associated with heating aerosol-generating products.

The following discussion of background is intended to facilitate an understanding of the present disclosure. However, it should be understood that the discussion is not an admission or admission that any of the material referred to was published, known or part of the common general knowledge in any jurisdiction before the priority date of the application.

A number of heat-not-burn devices and associated heating elements have been proposed. A typical heat not burn device includes a heating device/element operable to heat an aerosol-generating product having an aerosol-generating substrate. The aerosol-generating product may include tobacco material and one or more filter elements. Where the aerosol-generating product is replaced when tobacco material is consumed, the filter included in the replacement device may be wastefully discarded.

Additionally, current heating devices include heatable mouthpieces such that the heated mouthpiece may inadvertently burn the user's lips when the user first consumes the generated aerosol, i.e., the "first puff." Additionally, the heat profile used to heat the aerosol-generating product may not be optimized for a good taste profile that the user enjoys.

There is a need to develop heating devices, heating elements and/or aerosol generating products that at least partially ameliorate the above disadvantages.

According to one aspect of the present disclosure, a heating device as claimed in claims 1 to 9 is provided. According to another aspect of the disclosure there is provided an aerosol generating product as claimed in claims 10 to 14. Another aspect of the invention provides two- and three-stage products having an aerosol-generating substrate as defined in claims 15 to 21.

It is contemplated that the various aspects may be combined in at least one way, for example in the form of a kit comprising an aerosol-generating product as described and a heating device suitable for heating said aerosol-generating product.

Other aspects of the disclosure will be apparent to those of ordinary skill in the art upon reading the following description of specific embodiments of the disclosure in conjunction with the accompanying drawings.

The aerosol generating product 100 may be configured in the form of a capsule.

It will be appreciated that the embodiment depicted in Figures 1a to 1j is a single stage aerosol generating product. Such a single segment has the advantage of being compact and usable with the heating device 200 .

According to another aspect and as shown in Figure 2 (Figures 2a to 2k), there is a heating device 200 suitable for heating an aerosol generating substrate or product. The heating device 200 includes a suction portion 202 in the form of a mouthpiece/nose pad 202 that allows a user to consume aerosol generated from the aerosol-generating substrate; a support 204 for receiving an aerosol-generating substrate; and a heater An element 206 shaped and sized to heat the aerosol-generating substrate to generate an aerosol; an aerosol delivery channel 208 positioned to receive the aerosol generated by heating the aerosol-generating substrate and direct the aerosol toward the mouthpiece/ Nose pad 202.

The heating device 200 may be powered by electricity using a battery 214 contained within the heating device 200 . The battery 214 may be a lithium ion polymer (LiPo) battery. A charging port 216 may be provided in the device 200 to charge the LiPo battery. The charging port 216 may be a USB charging port or other known charging port (including a wireless charging port). The battery 214 may be electrically connected to the heating element 206 to increase the temperature of the heating element 206 to a desired temperature or temperature profile.

As the heating element 206 generates heat, heat dissipation areas or zones can be provided within the device 200 . The heat dissipation area may include one or more metal or alloy coatings, plates, and/or heat dissipation elements 240 to reduce heat within the device 200.

In some embodiments, a heat sink in the form of a fin-like structure may be positioned in an area proximate the mouthpiece/nose pad 202 . The heat sink may be formed by manufacturing methods such as, but not limited to, extrusion, die casting, machining processes, 3D printing, investment casting, and injection molding.

An insulating area may be included as one or more walls 209 surrounding the support 204 to isolate heat generated from the support 204 to prevent and minimize heat transfer to the device. Set the surface to 200. The insulating wall 209 may be positioned adjacent the heat dissipation element 240 to dissipate heat from the support 204 and insulate heat from the surface of the device 200 .

Referring to the embodiment shown in Figures 2a(i) to 2a(ii), the device 200 may comprise a clamp 250 as an alternative to the support 204 for housing an aerosol generating product and/or at least one filtration unit. things. The aerosol-generating product may be a single-stage aerosol-generating product 100 . The clamp 250 may include or may house a metal hollow or cup-shaped cylinder 207 to hold the aerosol-generating product. The cylinder 207 may be made of aluminum, copper, magnesium, stainless steel, or other conductive material to dissipate heat from the generated aerosol. go out. The clamp 250 can be adjusted for the length of the aerosol-generating product to facilitate insertion and removal of the aerosol-generating product from the support 204 . The holder may include a filter holder 210 for housing at least one filter 212 positioned proximate the mouthpiece 202 to filter particles from the generated aerosol prior to consumption by the user. The heating element 206 can have a sliding mechanism 213 so that the heating element 206 can move up and down to heat different lengths of the aerosol-generating product. The sliding mechanism 213 may have a biasing mechanism as known to those skilled in the art to bias the heating element 206 in different positions to accommodate different aerosol generating products.

In the embodiment of Figure 2a(iii), the portion of the device 200 that receives the clamp may be lined with an insulating material 244 in the form of plastic, metal, fiber, glass, ceramic, carbon, aerogel, etc. to insulate from The heating element 206 generates heat. Alternatively, the insulator 244 may include a vacuum chamber surrounding the heating element and/or the clamp 250 .

It will be appreciated that the base of the clamp may include a slot or hole for insertion of a heating element to contact the aerosol generating product 100 . When inserted, the aerosol-generating product 100 is sandwiched between the clamp 250 and the receiving portion 246 to prevent air leakage. The receiving portion 246 may include two or more biasing mechanisms such that when the clamp 250 is inserted, the force is is applied to the clamp 250 to securely hold the clamp 250 within the device 200 . In operation, air may enter the device 200 from any air gap 224 formed about the clamp 250.

Referring to Figure 2b, another embodiment of a device 200 is shown comprising two components 200a and 200b. The first portion 200a can serve as a device cover, housing the aerosol delivery channel 208, the filter holder 210 (with the filter 212 when present), and the support 204 (with the substrate 205 when present). The second portion 200b may serve as the device body, housing the battery 214, the charging port 216, any reset/actuator pins used to operate the device 218, and the heat dissipation element 240. In the embodiment shown in Figure 2b, the aerosol delivery channel 208 is a U-shaped channel arranged to connect an air pocket 220 (also called an airflow bag) located adjacent the support 204 to the filter holder 210. Figure 2c is a cross-sectional view showing the device of Figure 2b in operation, with the aerosol generating substrate 205 contacting the heating element 206 and the filter 212 being held in place by the filter holder 210.

When components 200a and 200b are connected and the device 200 is operated using the actuator 218, the heating element 206 is heated to a desired temperature. As a result, the aerosol-generating substrate 205 and the air surrounding the substrate within the air pocket 220 are heated. Air from outside the device 200 is drawn into the device from adjacent one or more air gaps/inlets 224 defined at the interface between the components 200a, 200b toward the substrate 205. Air flowing toward the substrate 205 may be heated simultaneously with the substrate 205 and may then flow through the heat dissipation element 240, thereby lowering its temperature. The air sucked into the substrate 205 carries the aerosol generated through the heated substrate 205 toward the air pocket 220 and then to the U-shaped aerosol delivery channel 208 . The aerosol delivery channel 208 may be coated with a layer of metal, such as aluminum, copper, magnesium, stainless steel, or other conductive material (which effectively forms a heat sink) to prevent flow through the aerosol delivery channel 208 before entering the mouthpiece 202 to extract heat from the aerosol. The heat dissipation element 240 is positioned adjacent the aerosol delivery channel 208 to further assist in dissipating heat away from the aerosol delivery channel 208 .

Figure 2d shows another embodiment of the device 200. Instead of the two-part configuration shown in Figures 2b and 2c, the component 200a may further comprise components 200a1 and 200a2. This arrangement advantageously provides a cover that facilitates replacement of a filter 212. The part 200a1 may be called a device cover, and the part 200a2 may be called a device cover. The combined component 200a1 and component 200a2 accommodate the aerosol delivery channel 208, the filter holder 210 (with the filter 212 when present), and the support 204 (with the base material 205 when present). The second portion 200b may be referred to as a device body, housing the battery 214, the charging port 216, and any pin actuators used to operate the device 218 (including actuators for reset, on/off, operation control device), and heat dissipation element 240. In the embodiment shown in Figure 2d, the aerosol delivery channel 208 is a straight channel and may resemble the air pocket 220 located in the support 204 adjacent the filter holder 210. A monolithic heat dissipation element 240 including one or more metals (e.g., aluminum, copper, magnesium, stainless steel, or other conductive materials) may be positioned adjacent or adjacent the aerosol delivery channel 208 and the support 204 to assist in transporting the aerosol from the Passage 208 heat dissipates away. In the embodiment shown in Figure 2d, the nozzle 202 may be coated with a layer of metal such as aluminum, copper, magnesium, stainless steel or other conductive material (which effectively forms a heat sink) to remove air from the air flowing through the nozzle 202.

Figure 2e is a cross-sectional view showing the device of Figure 2d in operation, with the aerosol generating substrate 205 contacting the heating element 206 and the filter 212 being held in place by the filter holder 210.

When components 200a and 200b are connected and the device 200 is operated using the actuator 218, the heating element 206 is heated to a desired temperature. Therefore, the substrate 205 and the air surrounding the substrate within the aerosol delivery channel (air pocket 220) are heated. Air from outside the device 200 is drawn into the device from near one or more air gaps/inlets 224 defined at the interface between components 200a, 200b toward the substrate 205. flow to the substrate 205 which can be heated at the same time Air can flow through the heat dissipation element 240, thereby reducing its temperature.

When components 200a and 200b are connected and the device 200 is operated using the actuator 218, the heating element 206 is heated to a desired temperature. Therefore, the substrate 205 and the air surrounding the substrate in the aerosol delivery channel 208 (air pocket 220) are heated. Air from outside the device 200 is drawn into the device from near one or more air gaps/inlets 224 at the interface between components 200a, 200b towards the substrate 205. Air drawn into the substrate 205 carries aerosols generated by heating the substrate 205 toward the air pockets 220 that form part of the aerosol delivery channel 208 adjacent the liver support 204 . A portion of the aerosol delivery channel 208 is coated with a layer of metal to facilitate heat transfer. adjacent to the aerosol delivery channel One or more heat dissipation elements 240 positioned at 208 further assist in dissipating heat from the aerosol delivery channel 208 .

A suitable opening/gap is formed in the clamp 250 to allow excess material to be pushed out of the clamp 250.

Figure 2j illustrates another embodiment suitable for use with the various embodiments of Figures 2a to 2i, wherein a heat sink in the form of a fin-like structure may be positioned adjacent the area of the mouthpiece/nose pad 202. The heat sink may be formed by manufacturing methods such as, but not limited to, extrusion, die casting, machining procedures, 3D printing, investment casting, and injection molding.

Figure 2k shows an embodiment where the area/wall surrounding the heating element 206 may be coated/laminated with a metal such as aluminum, copper, stainless steel or alloy 252 in the form of fibers, strips, sheets, chips, powders or Particles. The outer surface of the device 200 is in direct contact with the environment, such as The surface may be formed by or from a metal or alloy (such as aluminum alloy or plastic).

Feedback can then be sent to a controller (not shown) to provide temperature control based on one or more heating profiles (see Figures 4a to 4e). The controller may be in the form of an integrated circuit chip (IC), such as, but not limited to, an application specific integrated circuit (ASIC) chip. Such an arrangement advantageously facilitates the controller's dynamic control of the heating profile of the heating element 206 and can optimize the power consumption of energy.

It will be appreciated that the device 200 operates by separating an aerosol-generating substrate (eg, tobacco) from the filter. This applies particularly to single-stage embodiments of the aerosol-generating product 100 . For an aerosol-generating product 100 having a section that includes a filter, the additional filter 212 may not be required during operation and the tank 210 may be empty.

In some embodiments, the aerosol delivery channel 208 and/or the mouthpiece may be coated with a heat dissipating material or heat sink. Suitable materials may be metals or alloys such as aluminum alloys, magnesium, stainless steel, or other conductive materials to extract heat from the nozzle 202.

The heating pin 314 may be shaped and sized to have a significantly thinner width than the heating element 302 .

The heating element may include an elongated body portion, a first end 304 adapted to receive electrical power, and a second end adapted to provide contact with the aerosol generating substrate.

In some embodiments, the second end 306 of the heating element includes a rounded tip or a tapered tip.

According to another aspect of the present disclosure, there is a controller for a heating device, such as the heating device 200 depicted in Figures 2a to 2k. The controller may include a sensor for sensing the temperature and/or pressure of the heating element of the heating device. Alternatively, the heating device may include one or a plurality of sensors.

The pressure sensor may be configured to sense a pressure corresponding to a suction force exerted on a suction nozzle of the heating device. This suction, in turn, may correspond to the user consuming the aerosol through his/her mouth (i.e., "puffing"). To heat the heating element, you can A circuit may be arranged to send current directly to the heating element or to induce current flowing through the heating element.

It is contemplated that, in operation, the controller may be arranged to increase the temperature from room temperature to a first rest temperature and a first operating temperature, wherein the first operating temperature is related to the suction force detected by the pressure sensor. Union.

Figures 4a to 4e show five heating curves corresponding to various resting and operating temperatures.

Figure 4a shows a first heating profile that the controller is programmed to provide. The first heating profile includes the first rest temperature between 200 degrees Celsius (°C) and 400 degrees Celsius, and the first operating temperature above 200 degrees Celsius and up to 400 degrees Celsius. In operation, the heating element heats from room/ambient temperature to the first resting temperature. When the pressure sensor detects that a suction force is applied to the suction nozzle 202, the controller operates to heat the heating element to an operating temperature of up to 400°C. When the suction force is no longer applied, the temperature of the heating element falls back to the first resting temperature. The process repeats itself until reset or the aerosol generating substrate is consumed. In the embodiment shown in Figure 4a, the first rest temperature may be in the range of 300°C to 350°C.

Figure 4b shows a second heating profile that the controller is programmed to provide. The second heating curve includes the first rest temperature in a temperature range of 250°C to 400°C, and the first operation below the first rest temperature and in a temperature range of 200°C to 350°C. temperature, and a second rest temperature is higher than the first operating temperature, and the second rest temperature is lower than the first rest temperature. In operation, the heating element heats from room/ambient temperature to the first resting temperature. When the pressure sensor detects that a suction force is applied to the suction nozzle 202, the controller operates to cool the heating element to an operating temperature of approximately 200°C. When suction is no longer applied, the temperature of the heating element rises to the a resting temperature. However, after the user performs a predetermined number of "pumps", the temperature of the heating element remains at the second resting temperature regardless of whether the pressure sensor detects subsequent suction. The predetermined number of "puffs" may be three puffs, and the second rest temperature may be a temperature lower than the first rest temperature but higher than the first operating temperature.

Figure 4c shows a third heating curve that the controller is programmed to provide. The third heating curve includes the first rest temperature in a temperature range from 200 degrees Celsius (°C) to 400°C, a second rest temperature lower than the first rest temperature and above 200°C, the first operation The temperature is lower than the first rest temperature and is at least 200°C or above, and a second operating temperature is higher than the second rest temperature and can reach up to 400°C. In operation, the heating element heats from room/ambient temperature to the first resting temperature. When the pressure sensor detects that a suction force is applied to the nozzle 202, the controller operates to cool the heating element to an operating temperature of approximately 200°C. When suction is no longer applied, the temperature of the heating element rises to the first rest temperature. However, after the user takes a predetermined number of "puffs" (eg, 3), the temperature of the heating element drops to the second resting temperature. When the user takes further/subsequent puffs, the controller operates to heat the heating element to an operating temperature of up to 400°C, and the second rest temperature is below the first rest temperature but above the third rest temperature. A temperature of operating temperature. It can be understood that the third heating curve can be regarded as a combination of the second heating curve and the first heating curve.

Figure 4d shows a fourth heating profile that the controller is programmed to provide. The fourth heating profile may include the first rest temperature in the range from 200 degrees Celsius (°C) to 400°C, the first operating temperature above the first rest temperature up to 400°C, and above 200°C. °C and a second operating temperature below the first rest temperature. In operation, the heating element heats from room/ambient temperature to the first resting temperature. When the pressure sensor detects that a suction force is applied to the suction nozzle 202, the controller operates The heating element is heated to an operating temperature of approximately 400°C. When the suction force is no longer applied, the temperature of the heating element drops to the first rest temperature. However, after the user takes a predetermined number of "puffs" (e.g., 3), subsequent puffs cause the temperature of the heating element to drop below the first resting temperature, and the release of suction causes the temperature to increase to the First resting temperature. It can be understood that the fourth heating curve can be regarded as a combination of the first heating curve and the second heating curve.

Figure 4e shows a fifth heating curve that the controller is programmed to provide. The fifth heating profile may include the first rest temperature in a range from 200 degrees Celsius (°C) to 400°C, and a first operating temperature above the first rest temperature and up to 400°C. In operation, the heating element heats from room/ambient temperature to the first resting temperature. When the pressure sensor detects that a suction force is applied to the nozzle 202, the controller operates to increase the heating element to an operating temperature of approximately 400°C. When the suction force is no longer applied, the temperature of the heating element remains at the operating temperature.

Obviously, temperatures of 200°C and/or 400°C are arbitrary. Other resting and operating temperatures with similar curves to one of the five heating curves described are conceivable.

It can be understood that, in some embodiments, the controller can control the heating curve of the heating element through logic instructions or software programs preloaded into the controller. In some embodiments, the controller can dynamically control the heating profile of the heating element based on input and feedback from temperature sensors and pressure sensors placed in the heating device (eg, device 200) to track the actual temperature of the aerosol and pressure.

It will be appreciated that one or more different heating curves, to the extent that they are not inconsistent in operation, can be combined and preloaded into the controller.
