Referring to Figure 2b, another embodiment of an apparatus 200 comprising two components 200a and 200b is shown. The first portion 200a may serve as a device cover housing the aerosol delivery channel 208, filter holder 210 (with filter 212, when present), and support 204 (with substrate 205, when present). The second part 200b may serve as the device body, housing the battery 214 , charging port 216 , any pin resets/actuators for operating the device 218 , and the heat sink 240 . In the embodiment shown in FIG. 2 b , the aerosol delivery channel 208 is a U-shaped channel arranged to connect an air pocket 220 (also referred to as an air pocket) located near the support 204 to the filter holder 210 . FIG. 2c is a cross-sectional view showing the device of FIG. 2b in operation, with the aerosol-generating substrate 205 contacting the heating element 206 and the filter 212 held in place by a filter holder 210 .

When the 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. Thus, the air surrounding the aerosol-generating substrate 205 and the substrate within the cavitation 220 is 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 the components 200a, 200b towards the substrate 205 . Air flowing to the substrate 205 may be heated simultaneously with the substrate 205 and then may flow through the heat sink 240, thereby reducing its temperature. The air drawn 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 allow the aerosol to flow through the aerosol delivery channel 208 before entering the suction nozzle 202. Extract heat from the aerosol. The heat sink 240 is positioned adjacent to the aerosol delivery channel 208 to further assist in dissipating heat away from the aerosol delivery channel 208 .

Another embodiment of the device 200 is shown in FIG. 2d. Instead of the two-part configuration shown in Figures 2b and 2c, the component 200a may further include components 200a1 and 200a2. This arrangement advantageously provides a cover for easy replacement of a filter 212 . The part 200a1 may be referred to as a device cover, and the part 200a2 may be referred to as a device cover. Combined part 200a1 and part 200a2 house the aerosol delivery channel 208, filter holder 210 (with filter 212, when present), support 204 (with substrate 205, when present). The second part 200b may be referred to as a device body, housing the battery 214, the charging port 216, any pin actuators for operating the device 218 (including actuation for reset, on/off, operation control device), and radiator 240. In the embodiment shown in FIG. 2 d , the aerosol delivery channel 208 is a straight channel and may be similar to the air pocket 220 located in the support 204 adjacent the filter holder 210 . A monolithic heat sink 240 comprising one or more metals (e.g., aluminum, copper, magnesium, stainless steel, or other conductive material) can be positioned near or adjacent to the aerosol delivery channel 208 and the support 204 to help transport the aerosol from the Channel 208 dissipates heat. In the embodiment shown in FIG. 2d, the suction 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) Heat is extracted from the sol.

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

When the 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. Thus, the substrate 205 and the air surrounding the substrate within the aerosol delivery channel (cavity 220) are heated. Air from outside the device 200 is drawn into the device towards the substrate 205 from near one or more air gaps/inlets 224 defined at the interface between the components 200a, 200b. Air flowing to the substrate 205, which can be heated at the same time, can flow through the heat sink 240, thereby reducing its temperature. The air drawn into the substrate 205 carries the aerosol generated by heating the substrate 205 toward the air pocket 220 and then to the aerosol delivery channel 208 adjacent to the support 204 . The heat sink 240 positioned adjacent to the aerosol delivery channel 208 further assists in dissipating heat from the aerosol delivery channel 208 .

Another embodiment of the device 200 is shown in FIG. 2f. The aerosol delivery channel shown in Figure 2f is not a U-shaped aerosol delivery channel or a straight delivery channel 208, but a Z-shape. The embodiment of Fig. 2f also shows the part 200a housing only the support 204, while other components are housed by the part 200b. The support 204 may be shaped and dimensioned to receive a hollow tube corresponding to the substrate 205 within the support. To facilitate proper airflow within the device 200, mechanical gaskets, such as O-rings 260, may be positioned at the various joints. A cup or cylindrical structure 207 may line the support 204 to accommodate the substrate 205 .

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

When the 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. Thus, the substrate 205 and the air surrounding the substrate within the aerosol delivery channel 208 (air pocket 220) are heated. Air from outside the device 200 is drawn into the device towards the substrate 205 from near one or more air gaps/inlets 224 at the interface between the components 200a, 200b. The air drawn into the substrate 205 carries the aerosol generated by heating the substrate 205 towards the air pocket 220 forming part of the aerosol delivery channel 208 adjacent to the liver support 204 . A layer of metal is coated on a portion of the aerosol delivery channel 208 to facilitate heat transfer. One or more heat sinks 240 positioned adjacent to the aerosol delivery channel 208 further assist in dissipating heat from the aerosol delivery channel 208 .

It is contemplated that various features of the embodiments shown in Figures 2b, 2d and 2f are combinable. As a non-limiting example, the aerosol delivery channel 208 and the nozzle 202 of each embodiment may be coated with a conductive material to form another embodiment. As another example, the O-ring 260 or other suitable gasket may be positioned in the device 200 as shown in Figures 2b and 2d.

In the embodiment shown in Figures 2a to 2k, the aerosol delivery channel and/or the coating on the nozzle can be regarded as a first thermal conductor. The metal plate adjacent to the aerosol delivery channel can be considered a second thermal conductor operable to dissipate heat away from the first thermal conductor.

Figure 2h shows an embodiment with a similar external profile to the device shown in Figure 2d. The device cover 200a1 may be rotated relative to the device cover 200a2 to removably separate the device cover 200a1 from the device cover 200a2. The device cover 200a2 includes a slot for receiving the clamp 250, except in the embodiment shown in FIG. 2h, the suction nozzle 202 is not part of the clamp 250. The compartment of the fixture 250 for receiving the aerosol-generating substrate may be lined/coated with a suitable thermally conductive material.

Figure 2i shows an embodiment of a clamp 250 wherein the portion of the clamp 250 receiving the aerosol generating substrate allows excess material to be pushed out of the substrate in use. A suitable opening/gap is formed in the jig 250 to allow excess material to be pushed out of the jig 250 .

FIG. 2j illustrates another embodiment suitable for use with the various embodiments of FIGS. 2a-2i , wherein a heat sink in the form of a fin-like structure may be positioned at an area close to the nozzle/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 fibres, strips, sheets, chips, powder or particles. External surfaces of the device 200, such as surfaces that are in direct contact with the environment, may be formed of or formed of a metal or alloy, such as aluminum alloy or plastic.

Figure 21 shows another embodiment of the device 200 comprising a through hole or through hole 270 spanning the device 200, the through hole 270 comprising the aerosol delivery channel 208 and the support 204, wherein the through hole 270 is a first One end 270a is sized to slidably receive the suction portion 202 , an aerosol-generating substrate 205 and/or a filter 212 .

In the embodiment shown in FIG. 21 , the heating element 206 may be a hollow cylinder surrounding a portion of the through hole 270 . As seen from the cross-sectional view, including the first cross-sectional side 206a and the second cross-sectional side 206b, when the aerosol-generating substrate 205 is located within the through-hole 270 at a position corresponding to the hollow portion of the hollow cylinder , they are configured to conduct heat through the through hole 270 . From the cross-sectional view, the aerosol-generating substrate 205 is positioned between the first cross-sectional side 206a and the second cross-sectional side 206b.

It is conceivable that a user can insert the aerosol-generating substrate 205 through the first end 270a of the through hole 270. The suction portion 202 may be shaped and sized to push the aerosol-generating substrate 205 toward a position between the first cross-sectional side 206a and the second cross-sectional side 206b.

The through hole 270 may be sized to receive a filter unit 500 , wherein the filter unit 500 is positioned in operation such that heated aerosol is directed through the filter unit 500 before reaching the suction portion 202 .

As an alternative or in addition to the various heat sink configurations as described, one or more temperature sensors may be positioned in the device 200 to provide feedback on the temperature of the aerosol. Feedback can then be sent to a controller (not shown) to provide temperature control according to 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 dynamic control of the heating profile of the heating element 206 by the controller and may optimize power consumption of energy.

It will be appreciated that the device 200 works by separating an aerosol-generating substrate (eg, tobacco) from the filter. This applies particularly to the one-piece embodiment of the aerosol-generating product 100 . For an aerosol-generating product 100 having a segment that includes a filter, the additional filter 212 may not be required in operation and the tank 210 may be empty.

In some embodiments, the aerosol delivery channel 208 and/or the nozzle 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 .

Figures 3a to 3c show various embodiments of heating elements for use with a heating device, such as but not limited to heating device 200, to heat at least one aerosol-generating substrate without burning the at least one aerosol-generating substrate, such as, but not limited to Limited to the aerosol-generating substrate 104, wherein the heating element 302 is shaped and dimensioned to be in thermal contact with the at least one aerosol-generating product. Figure 3d shows embodiments wherein at least one heater pin 314 is formed from metal, alloy, ceramic, nickel and silver plated or other composite material with or without coating. The heater pin 314 may be shaped and sized to have a significantly thinner width than the heater 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. The tapered tip 306 may be a frusto-conical tip or may include one or a plurality of chamfered surfaces, or a circular cross-section with at least two recesses. The interior of the tip 306 may be hollow or partially hollow. The interior of the elongated body portion may be hollow or partially hollow.

In some embodiments, the elongated body portion of the heating element has an L-shaped cross-section, a V-shaped cross-section, a phi (Φ)-shaped cross-section, a C-shaped cross-section, a J-shaped cross-section, an X-shaped cross-section, a Y-shaped cross-section, a T at least one of a rectangular section, a triangular section or a rectangular section.

In some embodiments of the heating element, the heating element has a coin or flat shape 308 . In other embodiments, the heating element has a cylindrical shape 310 such that the inner surface of the cylinder is in thermal contact with the aerosol-generating product 102 . In some embodiments, heating may be accomplished through an inductor or inductor element. In some embodiments, the heating element has a tubular shape 320, which can be considered to be similar in shape to the cylindrical shape 310, but with the base removed to form the through hole.

In some embodiments of the heating element, the body portion consists of or is formed from aluminium. In other embodiments, the body portion may be composed/formed of other materials, such as glass/fiberglass.

While the heating element shown in Figures 3a to 3c is in the form of an elongated tube and may be hollow to receive an electrical circuit or substrate, it will be appreciated that other shapes and sizes may be envisioned to receive aerosols of different shapes and sizes Generate substrate.

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

The pressure sensor may be configured to sense a pressure corresponding to a suction force applied to a suction nozzle of the heating device. This suction force may in turn correspond to the user consuming the aerosol through his/her mouth (ie "puffing"). In order to heat the heating element, an electrical circuit may be arranged to send current directly to the heating element or to induce a 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 resting temperature and a first operating temperature, wherein the first operating temperature is correlated with the suction detected by the pressure sensor couplet.

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

Figure 4a shows a first heating profile that the controller is programmed to provide. The first heating profile includes the first resting 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 rest temperature. When the pressure sensor detects that a suction force is applied to the nozzle 202, the controller operates to heat the heating element to an operating temperature of up to 400°C. When the suction is no longer applied, the temperature of the heating element falls back to the first rest 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 resting temperature within a temperature range of 250∘C to 400∘C, and the first resting temperature lower than the first resting temperature and within a temperature range of 200∘C to 350∘C A first operating temperature, and a second rest temperature higher than the first operating temperature, the second rest temperature lower than the first rest temperature. In operation, the heating element heats from room/ambient temperature to the first rest 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 first rest temperature. However, after a predetermined number of "puffs" by the user, the temperature of the heating element remains at the second rest 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 profile the controller is programmed to provide. The third heating curve includes the first resting temperature within a temperature range from 200 degrees Celsius (∘C) to 400∘C, a second resting temperature that is 200∘C or more lower than the first resting temperature, the A first operating temperature is lower than the first static temperature and at least 200∘C, and a second operating temperature is higher than the second static temperature and can be up to 400∘C. In operation, the heating element heats from room/ambient temperature to the first rest 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 first rest temperature - the temperature of the 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, the controller being programmed to provide the fourth heating profile. 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 A second operating temperature above 200∘C and below the first resting temperature. In operation, the heating element heats from room/ambient temperature to the first rest temperature. When the pressure sensor detects that a suction force is applied to the nozzle 202, the controller operates to heat the heating element to an operating temperature of approximately 400∘C. When the suction 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" (eg, 3), subsequent puffs cause the temperature of the heating element to drop below the first resting temperature, and release of the suction causes the temperature to rise below the first resting temperature. 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 profile, the controller being programmed to provide the fifth heating profile. The fifth heating profile may include the first rest temperature ranging 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 rest temperature. When the pressure sensor detects that a suction force is applied to the suction nozzle 202, the controller operates to increase the heating element to an operating temperature of approximately 400∘C. When the suction is no longer applied, the temperature of the heating element remains at the operating temperature.

Obviously, the temperatures of 200∘C and/or 400∘C are arbitrary. Other resting and operating temperatures can be envisioned having profiles similar to one of the five heating profiles described.

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, a controller can dynamically control the heating profile of the heating element based on input and feedback from temperature and pressure sensors placed in the heating device (e.g., device 200) to track the actual temperature and temperature of the aerosol. pressure.

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

The third compartment 616 serves as the connecting portion between the first compartment 610 and the second compartment 612, and may generally be made of less material or more material than the first compartment 610 and the second compartment 612. Less material is formed because the third compartment 616 does not house any aerosol generating products or filter elements. Having less material associated with the third compartment 616 can facilitate reducing heat transfer to the second compartment 612 .
