Description

Technical Field

[0001] This disclosure relates to an electronic device, such as an aerosol generating apparatus. This disclosure also relates to an aerosol generating system comprising an aerosol generating apparatus and an aerosol generating article. This disclosure further relates to a method for heating a battery in an electronic device. Background Technology

[0002] Electronic devices powered by batteries are known. An aerosol generating apparatus for generating inhalable vapors powered by a battery is also known. Such apparatus heats an aerosol-forming matrix to a temperature that causes one or more components of the aerosol-forming matrix to volatilize without burning the aerosol-forming matrix. The aerosol-generating article may have a strip-like shape for inserting the aerosol-generating article into a cavity (e.g., a heating chamber) of the aerosol-generating apparatus. Heating elements may be arranged in or around the heating chamber to heat the aerosol-forming matrix after the aerosol-generating article is inserted into the heating chamber of the aerosol-generating apparatus. The electricity required to heat the aerosol-forming matrix may be provided by a battery.

[0003] It is known that batteries (e.g., lithium-ion batteries) have problems operating at low temperatures. It is also known that storing batteries (e.g., lithium-ion batteries) at low temperatures has problems. Low temperatures can be temperatures ranging from below 0 degrees Celsius to 5 degrees Celsius. At low temperatures, both the capacity and voltage of the battery may decrease. This can cause battery-powered electronic devices to malfunction at low temperatures. Furthermore, between operations, when the device is not in use, both the capacity and voltage of the battery may decrease in low-temperature environments. Additionally, charging rechargeable batteries in electronic devices at low temperatures may damage the battery.

[0004] It is known to include an additional heater in electronic devices to heat the battery and thus prevent it from becoming too cold. Generally, including an additional heater requires incorporating various additional components into the device. Including additional components can adversely increase the cost of the device. Including additional components may make the device heavier. A heavier device may be uncomfortable for the user to carry. Including an additional heater component may result in an unexpectedly large device. A larger device may be uncomfortable for the user to carry. Furthermore, if the device has multiple sensing circuits, and the various inductors are closely stacked on top of each other, their mutual inductance may reduce their effectiveness.

[0005] It is also known that battery operation is problematic at excessively high temperatures. When a battery is exposed to excessively high temperatures, its lifespan (e.g., lithium-ion batteries) may be adversely affected. Batteries that are constantly heated by an additional heater during use can be exposed to excessively high temperatures. Summary of the Invention

[0006] Electronic devices are desired to prevent the battery from overcooling during operation. Electronic devices are desired to heat the battery using existing components already included in the device. Electronic devices are desired to remain lightweight for comfortable user carrying. Electronic devices are desired to remain compact for comfortable user carrying. Electronic devices are desired to avoid invariably heating the battery to undesirable high temperatures.

[0007] According to one embodiment of the present invention, an electronic device is provided, comprising a battery and a heater for heating the battery. One or both of the battery and the heater may be movably mounted in the device. The battery and the heater may be movable relative to each other between a proximal position and a distal position, wherein the proximal position may be different from the distal position.

[0008] According to one embodiment of the present invention, an electronic device is provided, comprising a battery and a heater for heating the battery. One or both of the battery and the heater are movably mounted in the device. The battery and the heater are movable relative to each other between a proximal position and a distal position, wherein the proximal position and the distal position are different.

[0009] By providing a battery and a heater that can move relative to each other between a proximal position and a distal position, the heater can be configured to heat the battery in the proximal position. In the proximal position, the heater can be in thermal contact with the battery, particularly sufficient to heat the battery. In the distal position, the heater can be thermally insulated from the battery, particularly sufficient to prevent the heater from significantly heating the battery. The amount of heat transferred from the heater to the battery in the proximal position may exceed the amount of heat transferred from the heater to the battery in the distal position.

[0010] Because the battery and heater can move relative to each other between the near and far positions, a poorly heated battery can be heated to the desired temperature by moving to the near position. In the near position, the poorly heated battery can be heated to the desired temperature during operation of the device. In the near position, the poorly heated battery can be heated to the desired temperature between operations of the device. Because the battery and heater can move relative to each other between the near and far positions, overheating of the battery can be prevented by moving to the far position. Because the battery and heater can move relative to each other between the near and far positions, existing components of the device can be used to heat the battery. This avoids implementing an additional battery heater into the device. It saves on production costs. The device can be designed to be smaller and lighter, or both. It improves the portability and convenience of the device.

[0011] The battery can be configured as a power source for powering one or more functions of an electronic device. The battery can also be configured as a power source for powering a heater to heat the battery. The battery can be any type of battery as described herein.

[0012] Electronic devices may include thermally insulating elements configured to reduce thermal contact between a heater and a battery in a distal position. In the distal position, the thermally insulating element may be spatially positioned between the heater and the battery. The thermally insulating element may include a thermally insulating material, such as fiberglass, polystyrene, polyurethane foam, or other thermally insulating materials generally known to those skilled in the art. The thermally insulating element may have a relatively flat, rectangular, or disc-shaped shape. The thermally insulating element may include an opening. The opening may be an opening between two opposite sides of the thermally insulating element. The opening may include a reclosable door. The opening may include a slot. One or both of the battery and the heater may move through the opening as the battery and the heater move toward each other between a proximal and distal position. In the proximal position, the battery and the heater may be located on the same side of the thermally insulating element. In the distal position, the battery and the heater may be located on opposite sides of the thermally insulating element.

[0013] One or both of the battery and the heater can be mounted on a flexible substrate. The use of a flexible substrate allows components to be easily moved within the device. This movement can be free in three dimensions, or it can be constrained by physical structure to move in a plane, or further constrained to move along a line. Movement can allow for changes in the spacing between components. Some components mounted or printed on the flexible substrate can also be flexible; for example, lines or rails can be bent to allow components to maintain electrical contact even when their relative positions change. Flexible substrates can be used to change the relative positions of components within an electronic device, and thus allow the battery to receive heating in some cases and not in others.

[0014] The flexible substrate may further include control electronics for the device. The flexible substrate can be rolled into a tube. By rolling the flexible substrate into a tube, the flexible substrate adopts a tubular shape.

[0015] Both the heating element and the control electronics can be printed on the flexible substrate, for example, using metallic ink. During assembly, due to the flexible nature of the substrate, the flexible substrate, including one or both of the battery and the heater, can be rolled up to form a desired shape, for example, a tubular shape.

[0016] The flexible substrate may be electrically insulating. It may be a flexible dielectric substrate. The flexible substrate may include polyimide. The flexible substrate may be made of polyimide. The substrate may include any suitable material, and is preferably a material capable of withstanding high temperatures (e.g., temperatures in the range of 150°C to 250°C, or temperatures in the range of 250°C to 350°C) and rapid temperature changes. Examples of suitable materials are polyimide films, such as…

[0017] Individual portions of the flexible substrate can be folded onto each other before being rolled into a tube. If the individual portions have similar or identical shapes, the available space allows for a simpler and more optimal layered arrangement of the individual portions. A first portion of the flexible substrate can be arranged at least partially coaxially around the outer periphery of a second portion of the flexible substrate. After being rolled into a tube, both the first and second portions of the flexible substrate can have a hollow tubular shape. In one embodiment, the flexible substrate is laminated before being rolled into a tube.

[0018] The coaxial arrangement of the first portion of the flexible substrate relative to the outer periphery of the second portion of the flexible substrate can produce a compact arrangement, such as a compact heater. The compact heater can be arranged around the cavity of the aerosol generation apparatus for heating the aerosol forming matrix of the aerosol-generating article received in the cavity.

[0019] The flexible substrate may have a thickness between 0.02 mm and 4.50 mm, preferably between 0.035 mm and 2.75 mm.

[0020] The flexible substrate may include a movable portion. The movable portion may be movably mounted in a device. The flexible substrate may include a fixed portion. The fixed portion may be fixedly mounted in the device. The movable portion may be relatively movable relative to the fixed portion. Components may be fixedly mounted in the device by means of the fixed portion attached to the flexible substrate. One of a first portion and a second portion of the flexible substrate may be a movable portion, and the other portion may be a fixed portion. The movable portion and the fixed portion of the flexible substrate may be integrally formed. Therefore, the movable portion and the fixed portion of the flexible substrate may be separate parts of a single flexible substrate.

[0021] The flexible substrate may be in the form of a folded sheet. The folded sheet may include a first layer covered with a second layer. The first layer may be fixedly mounted to the body of the device and therefore may include a fixed portion. The second layer may include a movable portion.

[0022] The movable portion may include a groove. The groove can engage with a corresponding sliding support, thus allowing linear movement of the movable portion.

[0023] The movable part can be movably mounted to the body of the device by means of a sliding support.

[0024] The movable part may include a sliding clamp to allow the user to manually move the movable part. The sliding clamp can slide along the longitudinal axis of the electronic device.

[0025] The movable part may include a motor for automatically moving the movable part. The motor may be one or both of an electric motor and a linear motor.

[0026] Electronic devices may include temperature sensors. Temperature sensors can sense one or both of the ambient temperature and the battery temperature. Temperature sensors can also sense the temperature of another component of the device. The temperature of this other component can be used to estimate the battery temperature.

[0027] The device can be configured to move a battery and a heater relative to each other between a near position and a far position in response to a temperature sensed by a temperature sensor. The device may include a controller configured to receive and process the temperature signal from the temperature sensor. The controller may send a signal to a motor based on the signal received from the temperature sensor to cause the battery and heater to move relative to each other between the near and far positions.

[0028] The electronic device may include a temperature-sensitive element configured to move a battery and a heater relative to each other between a proximal and a distal position. The temperature-sensitive element may be configured to automatically move the battery and heater relative to each other between a proximal and a distal position.

[0029] Temperature-sensitive elements may include temperature-responsive elements that can change their shape or size in response to temperature changes. The battery and heater can move relative to each other between proximal and distal positions through changes in the shape or size of the temperature-responsive element. By using a temperature-responsive element, the battery and heater can automatically move relative to each other between proximal and distal positions based on the temperature of the temperature-responsive element. This automatic relative movement between proximal and distal positions based on temperature eliminates the need for a separate temperature sensor. The temperature-responsive element may include a bimetallic strip.

[0030] The temperature-sensitive element may include a temperature sensor and an actuator. The temperature-sensitive element may be a temperature sensor as described herein. The temperature sensor senses the temperature of the battery. The actuator may include a motor. The motor may be one or both of an electric motor and a linear motor. The output of the temperature sensor may be received by a controller. The controller may be included in the main control unit of the device, or it may be a separate controller for the temperature-sensitive element. The controller may be configured to operate the actuator. The actuator may be controlled based on signals received from the controller. The controller's signals may depend on the received output of the temperature sensor. The controller may be configured to operate the actuator based on the temperature signal received from the temperature sensor. The actuator may operate to move the battery and heater relative to each other between a near position and a far position based on the temperature measured by the temperature sensor. When the temperature measured by the temperature sensor is below a preset minimum value, the actuator may move the battery and heater relative to each other to a near position to heat the battery. When the temperature measured by the temperature sensor exceeds a preset maximum value, the actuator may move the battery and heater relative to each other to a far position without heating the battery.

[0031] The device may include a timer configured to automatically move the battery and heater relative to each other between a near position and a far position based on a preset time interval. The preset time interval may begin when the device is switched on. When the device is switched on using the battery, the heater may move relative to the near position so that the battery can first heat up to its operating temperature. After the preset time interval, the battery and heater may move relative to each other to the far position.

[0032] One of the battery and the heater can be mounted on a movable portion of the flexible substrate, such that the battery and the heater can be moved relative to each other by the movement of the movable portion. Another battery and the heater can be mounted on a movable portion of the flexible substrate, and the other battery and the heater can be mounted on a fixed portion of the flexible substrate, such that the battery and the heater can be moved relative to each other by the movement of the movable portion.

[0033] The heater may be an induction heater comprising an induction coil and a sensor, the battery may be fixedly mounted to the body of the device, and one or both of the induction coil and the sensor may be mounted on a movable part.

[0034] The heater may be an induction heater comprising an induction coil and a sensor. The induction coil may be fixedly mounted to the body of the device, the battery may be mounted on a movable part, and the sensor may be mounted on the battery or the induction coil.

[0035] The heater may be an induction heater comprising an induction coil and a sensor, and the device may further include a heating chamber in thermal contact with an additional sensor, and the heater may be configured to heat the heating chamber in a remote location. The heating chamber may be heated by heating the additional sensor.

[0036] The flexible substrate can have a hollow cylindrical shape. The flexible substrate can define a cavity in an electronic device. The cavity can be a heating chamber. One or both of the heater and the battery can have a hollow cylindrical shape. The battery and the heater can be coaxially aligned.

[0037] One or both of the heater and the battery may be movably mounted along the longitudinal axis of the electronic device.

The longitudinal axis of the battery may be parallel to the longitudinal axis of the heater.

[0039] The heating element may be formed from one or more resistance heating rails. The heating element may be composed of resistance heating rails. The resistance heating rails may be disposed on a flexible substrate. The resistance heating rails may be printed on the flexible substrate, for example, using metallic ink. A single resistance heating rail may be included. Alternatively, at least two resistance heating rails may be included. The resistance heating rails may function as resistance heaters.

[0040] Resistance heating rails can have a temperature coefficient that reflects resistance characteristics, allowing them to function as both a resistance heater and a temperature sensor.

[0041] The heating element, preferably in the form of a resistance heating rail, can be electrically connected to a power source. The heating element may comprise multiple parts. If the heating element is provided in the form of a resistance heating rail, the resistance heating rail may comprise multiple parts or multiple resistance heating rails. Each part of the heating element can be individually connected to a power source. This provides several advantages. First, it allows different parts to be heated for different durations depending on the properties of the aerosol-forming matrix, which can enhance the smoking experience. Second, it allows different parts to be heated at different temperatures depending on the properties of the aerosol-forming matrix, which also enhances the smoking experience. Third, it allows a specific part of the heater to be activated at any given time. This allows only a portion of the aerosol-forming matrix to be heated at any given time.

[0042] The heater may include a power source. Preferably, the power source is configured as a battery. The power source for the heater may be a battery heated by the heater or a different power source. The power source may be disposed on a flexible substrate. The power source may be configured as a lithium-ion battery. Alternatively, the power source may be a nickel-metal hydride battery, a nickel-cadmium battery, or a lithium-based battery such as a lithium-cobalt, lithium-iron-phosphate, lithium titanate, or lithium-polymer battery. Alternatively, the power source may be another form of charge storage device, such as a capacitor. The power source may require charging and may have a capacity capable of storing sufficient energy for one or more use experiences; for example, the power source may have sufficient capacity to continuously generate aerosols for approximately six minutes or multiples of six minutes. In another example, the power source may have sufficient capacity to provide a predetermined number of suction cycles or intermittent heater startups.

[0043] The power source can be flat. The power source can be a flat battery. The power source can be flexible. The power source can be a flexible battery. The power source can be both flat and flexible. The power source can be provided as a flexible flat sheet on a flexible substrate.

[0044] The heating element may include induction coils. The heating element may include at least two induction coils. The induction coils may be electrically connected to a power source. Controller electronics may be configured to control the electrical power supply from the power source to the induction coils. The induction coils may be configured to generate an alternating magnetic field. The induction coils may be movable relative to the battery.

[0045] The heater may further include a sensor. The heater may include a sensor for heating the battery. The sensor may be mounted on the battery. The sensor may be provided as an outer layer of the battery. The sensor may be provided as movable relative to the battery. The heater may include a sensor for heating the battery and additional sensors for performing different heating functions. The heater may include a sensor for heating the battery and additional sensors for heating the aerosol forming matrix.

[0046] The receptor can be flat. The receptor can be flexible. The receptor can be provided as a flexible flat sheet on a flexible substrate. The receptor can be disposed on a movable portion of the flexible substrate.

[0047] Generally, a sensor is a material capable of absorbing electromagnetic energy and converting it into heat when placed in an alternating magnetic field. If the sensor is conductive, eddy currents are typically induced by the alternating magnetic field. If the sensor is magnetic, another effect that typically contributes to heating is often called hysteresis loss. Hysteresis loss occurs primarily due to the movement of magnetic domains within the sensor, as the magnetic orientation of these domains aligns with the alternating magnetic field. Another effect contributing to hysteresis loss is when magnetic domains grow or shrink within the sensor. Typically, all these changes occurring in sensors at the nanoscale or below are called "hysteresis losses" because they generate heat within the sensor. Therefore, if the sensor is both magnetic and conductive, both hysteresis loss and eddy current generation contribute to heating the sensor. If the sensor is magnetic but non-conductive, hysteresis loss will be the only means of heating the sensor when the alternating magnetic field penetrates. According to the invention, the sensor can be conductive or magnetic, or both. An alternating magnetic field generated by one or more induction coils heats a sensor, which then transfers heat to one or both of the battery and the aerosol-forming matrix, thus forming an aerosol. Heat transfer can be primarily via thermal conduction. This heat transfer is optimal if the sensor is in close thermal contact with one or both of the battery and the aerosol-forming matrix.

[0048] The sensor can be formed of any material capable of sensing and heating to a temperature sufficient to heat one or both of the battery and the aerosol generated from the aerosol forming matrix. Preferred sensors may comprise, or be composed of, ferromagnetic or ferrimagnetic materials, such as ferromagnetic alloys, ferritic iron, or ferromagnetic steel or stainless steel. Suitable sensors may be aluminum or include aluminum. Preferred sensors can be heated to temperatures exceeding 250 degrees Celsius.

[0049] Preferred receptors are metallic receptors, such as stainless steel. However, receptor materials may also include or be made from a variety of the following: graphite; molybdenum; silicon carbide; aluminum; niobium; Inconel alloy (an austenitic nickel-chromium superalloy); metallized films; ceramics such as zirconium oxide; transition metals such as iron, cobalt, and nickel; or metalloid components such as boron, carbon, silicon, phosphorus, and aluminum.

[0050] Preferably, the receptor material is a metallic receptor material (metal refers to a metal in non-oxide form, often called ceramic). The receptor may also be a multi-material receptor and may include a first receptor material and a second receptor material. In some embodiments, the first receptor material may be positioned in close physical contact with the second receptor material. The Curie temperature of the first and / or second receptor materials is preferably below the combustion temperature of the aerosol-forming matrix. The first receptor material is preferably primarily used to heat the receptor when it is placed in a fluctuating electromagnetic field. Any suitable material can be used. For example, the first receptor material may be aluminum, or it may be an iron-containing material such as stainless steel. The second receptor material is preferably primarily used to indicate when the receptor has reached a specific temperature, which is the Curie temperature of the second receptor material. The Curie temperature of the second receptor material can be used to regulate the temperature of the entire receptor during operation. Suitable materials for the second receptor material may include nickel and certain nickel alloys.

[0051] By providing a sensor having at least a first sensor material and a second sensor material, the heating of the aerosol forming matrix and the temperature control of the heating can be separated. Preferably, the second sensor material is a magnetic material having a second Curie temperature that is substantially the same as the desired maximum heating temperature. That is, preferably, the second Curie temperature is approximately the same as the temperature to which the sensor should be heated in order to generate an aerosol from the aerosol forming matrix.

[0052] The term "Curie temperature" is broadly understood as the temperature at which a magnetic material loses its magnetic properties in the absence of an external magnetic field. Therefore, the Curie temperature is the temperature at which a ferromagnetic or ferrimagnetic material undergoes a phase transition and becomes paramagnetic.

[0053] When an induction heating element is used, the induction heating element can be configured as an external heater as described herein. If the induction heating element is configured as an external heating element, the sensor element is preferably configured as a cylindrical sensor that at least partially surrounds the cavity or forms the sidewall of the cavity.

The trimming layer may be wrapped around the heater.

[0055] In addition to heating the battery in one or both of the near and far positions, the heater may be configured to perform at least one additional function. This additional function may be an additional heating function.

The aerosol generating apparatus further includes a heater as described herein. The heater may be arranged at least partially coaxially around the outer periphery of the cavity.

[0058] The heater can be configured to heat the aerosol-forming matrix of the aerosol-forming article when it is received in the cavity. To optimize heat transfer from the heater to the aerosol-forming matrix, the heater can be arranged at least partially coaxially around the outer periphery of the cavity. In this way, heat can be transferred to the aerosol-forming matrix in a radially inward direction. Preferably, the heater is arranged completely coaxially around the outer periphery of the cavity.

[0059] A battery can be used as a power source for the aerosol generating apparatus. The heater's control electronics can be configured to control the power supply from the aerosol generating apparatus's power source to the heater's heating element. Alternatively, the heater may include a battery, and the aerosol generating apparatus may include an auxiliary power source, preferably an auxiliary battery. The heater's control electronics can be configured to control the power supply from the heater's power source and from the auxiliary power source of the aerosol generating apparatus to the heater's heating element.

The heater's control electronics can be configured to control the power supply from the heater's power source to the heating element. The aerosol generating apparatus's controller can be configured to control the power supply from the auxiliary power source of the aerosol generating apparatus to the heater's heating element.

[0060] The aerosol generating device may include a body. One or both of an auxiliary power source and a controller for the aerosol generating device may be disposed in the body. The aerosol generating device may include a mouthpiece. A cavity may be disposed in the mouthpiece. The mouthpiece may be integrally formed with the body. Alternatively, the mouthpiece may be configured to be removably attached to the body. The mouthpiece may include a mouthpiece. The mouthpiece may be configured to cover the cavity. Exemplarily, the mouthpiece may be connected to the mouthpiece via a hinge connection. Alternatively, the mouthpiece may be removably attached to the mouthpiece of the aerosol generating device. As another alternative, no mouthpiece is provided, and the user directly inhales from the proximal end of the aerosol-generated article received in the cavity of the mouthpiece.

[0061] The heater may at least partially form the sidewall of the cavity. Heat transfer can be optimized by having the heater at least partially form the sidewall. The heater may also completely form the sidewall of the cavity.

[0062] As used herein, the term "aerosol generating device" refers to an apparatus that interacts with an aerosol-forming matrix to generate an aerosol. The aerosol-forming matrix may be part of an aerosol-generating article, such as a smoking article.

[0063] The present invention further relates to a system comprising an aerosol generating apparatus as described herein and an aerosol generating article comprising an aerosol forming matrix.

[0064] As used herein, the term "aerosol-generating article" refers to an article comprising an aerosol-forming matrix capable of releasing volatile compounds that can form aerosols. For example, an aerosol-generating article can be a smoking article that generates aerosols that can be inhaled directly into a user's lungs through their mouth. Aerosol-generating articles can be disposable.

[0065] The aerosol-generating article can be substantially cylindrical in shape. The aerosol-generating article can be substantially elongated. The aerosol-generating article can have a length and a circumference substantially perpendicular to said length. The aerosol-generating article can be substantially rod-shaped. The aerosol-forming matrix can be substantially cylindrical in shape. The aerosol-forming matrix can be substantially elongated. The aerosol-forming matrix can also have a certain length and a circumference substantially perpendicular to said length. The aerosol-forming matrix can be substantially rod-shaped.

[0066] The aerosol-generating matrix may include an aerosol forming agent. Preferably, the aerosol-generating matrix comprises: homogenized tobacco material, an aerosol forming agent, and water. Providing homogenized tobacco material can improve aerosol generation, nicotine content, and aroma characteristics of aerosols generated during the heating of aerosol-generating articles. Specifically, the process of manufacturing homogenized tobacco involves grinding tobacco leaves, which more effectively releases nicotine and aroma upon heating.

[0111] Figure 1 a-1c shows different constructions of battery and heater devices for electronic devices.

[0112] Figure 1 A shows a battery 12 and a heater 14 arranged on a flexible substrate 16. The flexible substrate 16 is in an folded configuration. Figure 2 As illustrated in embodiments a and 2b, the flexible substrate 16 further includes a set of mounting points 18, which allow a portion of the flexible substrate 16 to be securely mounted to the body of the electronic device 10 via mounting joints 20. Figure 2 As illustrated in embodiments a and 2b, the flexible substrate 16 further includes a groove 22 that allows a movable portion of the flexible substrate 16 to be slidably mounted to the body of the electronic device 10 via a sliding support 24. Figure 1 b and Figure 1 As shown in Figure c, when installed in the electronic device 10, the flexible substrate 16 is folded so that the battery 12 and the heater 14 can move relative to each other between a near position and a far position.

[0113] Figure 1 b shows the first folded structure Figure 1 Arrangement a, in which battery 12 and heater 14 are moved to a remote position relative to each other.

[0114] Figure 1 c shows the arrangement in the second folded configuration, in which the battery 12 and heater 14 are moved to a close position relative to each other.

[0115] Figure 2 a and 2b show the components installed in the body of the electronic device 10. Figure 1 Different configurations of the battery and heater device from a to 1c. The heater includes a heating circuit 26. The heater may be a resistance heater, and the heating circuit 26 may include a resistance heating element. The heater may be an induction heater including an induction coil and a sensor. The heating circuit 26 may include an induction coil. The sensor may be mounted on the battery 12 or on the heating circuit 26.

[0116] The flexible substrate 16 is in the form of a folded sheet, which includes a first layer covered with a second layer. The first layer includes a fixed portion of the flexible substrate 16. The first layer is fixedly mounted to the body of the device 10 by means of a mounting joint 20. The second layer includes a movable portion of the flexible substrate 16. The second layer is movably mounted to the body of the device 10 by means of a sliding support 24. The movable portion includes a sliding clamp 28 for manual movement by a user. The sliding clamp 28 protrudes through a slot in the body of the device 10. The battery 12 is mounted on the movable portion of the flexible substrate 16. The user can grasp the sliding clamp 28 to move the movable portion of the flexible substrate 16. Thus, the battery 12 can move toward the heating circuit 26 and into a near position, or the battery 12 can move away from the heating circuit 26 and into a far position. By moving the sliding clamp 28 by the user, the relative placement of the battery 12 and the heating circuit 26 can be changed, and thus the heat experienced by the battery 12 can be changed.

[0117] Figure 2 Figure a shows a configuration in which the battery 12 and the heating circuit 26 are moved into a close position. Thus, the battery is brought close to the heating circuit 26, which includes a heating element, making the battery 12 heatable.

[0118] Figure 2b illustrates a configuration in which the battery 12 and heating circuit 26 are moved to a remote position. This distances the battery from the heating circuit 26, which includes the heating element, such that the battery 12 is not heated or is not significantly heated even when the heating element is on. Therefore, in the remote position, the heating element can be activated to provide different heating functions without overheating the battery. These different heating functions could be for heating the heating chamber of an electronic device.

[0119] Figure 3 a and 3b illustrate different configurations of embodiments of the battery and heater assembly installed in the body of the electronic device 10. Figure 3 The embodiments of a and 3b are similar Figure 2 Examples a and 2b. However, Figure 3 The embodiments of a and 3b do not include the sliding clamp 28. Instead, a temperature-dependent actuation mechanism is used. The temperature-dependent actuation mechanism includes a temperature-sensitive element 30 configured to automatically move the battery and heater relative to each other between a proximal and a distal position. Opposite ends of the temperature-sensitive element 30 are mounted to corresponding portions of the body of the device 10 and the movable portion of the flexible substrate 16 by means of corresponding attachment clamps 32. The temperature-sensitive element 30 includes a temperature sensor and an actuator. The actuator includes a linear motor to linearly move the movable portion of the flexible substrate 16. The output of the temperature sensor is received by a controller. The controller may be included in the main control unit of the device or may be a separate controller for the temperature-sensitive element 30. The controller is configured to operate the actuator. The actuator is controlled based on signals received from the controller. The signals of the controller depend on the received output of the temperature sensor. When the temperature sensor signals that the battery temperature is below the minimum operating temperature, the actuator moves the movable portion of the flexible substrate 16 to the proximal position. When the temperature sensor sends a signal that the battery temperature is higher than the maximum operating temperature, the actuator moves the movable portion of the flexible substrate 16 to a remote position.

[0120] Figure 3 a shows a configuration in which the battery 12 and heating circuit 26 are moved to a near position.

[0121] Figure 3 b shows a configuration in which the battery 12 and heating circuit 26 are moved to a remote position.

[0122] Figure 4 Figures a and 4b illustrate different configurations of an embodiment of a battery and heater assembly mounted in the body of the electronic device 10. The heater is an induction heater. The heating circuit 26 includes an induction coil. A sensor 34 is mounted on a movable portion of the flexible substrate 16. The battery 12 is not mounted on the flexible substrate 16. Instead, the battery 12 is fixedly mounted to different portions of the body of the device 10 by mounting connectors 20.

[0123] Figure 4 Figure a shows a configuration in which the battery 12 and the sensor 34 are moved to a remote position. In the remote position, the sensor 34 is far from the battery 12, such that heat transfer from the sensor 34 to the battery 12 is minimal.

[0124] Figure 4 b illustrates a configuration in which the battery 12 and the sensor 34 are moved into a proximal position. In the proximal position, the sensor 34 is close to the battery 12, such that there is sufficient heat transfer from the sensor 34 to the battery 12 to heat the battery 12 to the desired temperature.

[0125] Figure 5 Electronic device 10 is shown. Electronic device 10 is an aerosol generating apparatus. An aerosol generating article 36, including an aerosol forming matrix, can be inserted into a cavity 38 of the aerosol generating apparatus. A stop 40 is arranged at the base of the cavity 38. The stop 40 is configured to prevent the aerosol generating article 36 from being over-inserted into the cavity 38.

[0126] Cavity 38 is the heating chamber of device 10. Battery and heater assembly (e.g.) Figures 1 to 4 The battery and heater assembly shown in any of the figures are arranged around cavity 38 within the tubular body of the aerosol generating apparatus. A flexible substrate 16, including a movable portion, is arranged around cavity 38 within the tubular body of the aerosol generating apparatus. In addition to heating the battery 12 in a near position, the heater is further configured to heat the aerosol forming matrix of the aerosol generating article 36 in one or both a near and a far position.

[0127] Figure 6 Electronic device 10 is shown. Electronic device 10 is an aerosol generating device. Figure 6 An embodiment is shown in which the main power source is a cylindrical battery 12. The proximal portion 42 of the cavity 38 is configured as a heating chamber for heating the aerosol forming matrix of the aerosol generating article 36. The battery 12 is disposed within the distal portion 44 of the cavity 38. A flexible substrate 16 is disposed around the cavity 38 within the tubular body of the aerosol generating apparatus. A heater 14 is movably mounted on a movable portion of the flexible substrate 16, allowing the heater to move between a proximal position and a distal position. In the proximal position, the heater 14 is disposed around the distal portion 44 and configured to heat the battery 12. In the distal position, the heater is disposed around the proximal portion 42 and configured to heat the aerosol forming matrix of the aerosol generating article 36.

[0128] An end wall 46 is located at the distal end of the device. A sealing wall 48 is located between the aerosol generating article 36 inserted into the cavity 38 and the battery 12. The sealing wall 48 prevents the aerosol forming matrix from the aerosol generating article 36 from reaching and contaminating the battery 12. Furthermore, in the event of battery leakage, the sealing wall 48 prevents the receiving cavity 38 from being contaminated by undesirable chemical compounds. The sealing wall 48 may further function as a heat insulation element.
