Abstract
Description
Technical Field
[0001] This disclosure relates to an aerosol generating device. This disclosure is particularly applicable to portable aerosol generating devices, which may be stand-alone and cryogenic. Such devices can generate inhalable aerosols by heating, rather than burning, tobacco or other suitable aerosol matrix materials through conduction, convection, and / or radiation. Background Technology
[0002] In recent years, the popularity and use of devices that reduce or modify risk (also known as vaporizers) have grown rapidly, helping habitual smokers who want to quit to break traditional tobacco products such as cigarettes, cigars, cigarettes, and rolled cigarettes. Various devices and systems provide access to substances that are heated or vaporized, unlike the burning of tobacco in conventional tobacco products.
[0003] Typically available devices that reduce or mitigate risk are aerosol generating devices that heat a matrix or devices that heat but do not burn. This type of device generates aerosols or vapors by heating an aerosol matrix to a temperature typically in the range of 150°C to 300°C. This aerosol matrix usually comprises moist tobacco leaves or other suitable aerosolizable materials. Heating, but not burning or burning, the aerosol matrix releases aerosols that include the components sought by the user but exclude toxic and carcinogenic byproducts produced by combustion and burning. Furthermore, aerosols generated by heating tobacco or other aerosolizable materials generally do not include the burnt or bitter tastes that may be unpleasant to the user from combustion and burning; therefore, the matrix does not require sugars and other additives that are often added to such materials to make the smoke and / or vapor more palatable to the user.
[0004] Such devices typically include a heating chamber for heating the aerosol matrix and a power supply for supplying power to the heating chamber. The power supply is usually disposable or rechargeable, so the lifespan of the device is not limited by the single energy storage capacity of the power supply. Typically, the heating chamber needs to be heated rapidly in a relatively short time, which means that it is desirable to be able to supply high power to the heating chamber and to supply power efficiently.
[0005] Such devices are typically handheld, and preferably easy to hold and securely gripped even when the aerosol matrix is heated. Therefore, it is desirable to provide a device that can be easily and safely held in the hand.
[0006] In addition, it is desirable to provide a device that can perform heating efficiently, so that the user does not need to frequently change the power supply or recharge it. Summary of the Invention
[0007] According to a first aspect, this disclosure provides an aerosol generating apparatus comprising: a power source; a heating chamber operable to heat an aerosol matrix to generate an aerosol; a first control circuit system configured to control the power supply from the power source to the heating chamber; and a housing including a mouthpiece end and an opposite end, wherein the power source, the heating chamber, and the first control circuit system are arranged within an internal volume of the housing, the heating chamber being arranged between the first control circuit system and the mouthpiece end, and the first control circuit system being arranged between the heating chamber and the power source.
[0008] By arranging the contents of the housing according to the invention, the cross-section of the device can be reduced, and the device can be more easily held by the user. Furthermore, by arranging the control circuit system between the power supply and the heating chamber, the length of the electrical connection from the power supply to the heating chamber can be reduced. This also reduces resistive losses in the electrical connection and improves heating efficiency.
[0009] Optionally, the mouthpiece, the heating chamber, the first control circuitry, and the power supply are arranged along a common line. By arranging the heating chamber, the first control circuitry, and the power supply all in a single line extending through the mouthpiece, the device has a linear configuration that allows for a narrower and easier gripping arrangement.
[0010] Optionally, the first control circuit system includes a first PCB. By providing the first PCB as part of the first control circuit system, the control circuit system can be prepared as a single component that can be easily assembled into a device.
[0011] Optionally, the first PCB is arranged in a plane transverse to the common line. With this arrangement, the first PCB occupies very little space along the first direction. Given that the circuit components are generally small relative to the power supply and heating chamber in the aerosol generating device, this arrangement helps to efficiently assemble the device's components into the smallest possible housing. Additionally, with this arrangement, the first PCB can provide thermal insulation between the heating chamber and the power supply.
[0012] Optionally, the first PCB includes electrical contacts for connecting to the power supply and electrical contacts for connecting to the heating chamber. By providing electrical contacts to both the power supply and the heating chamber on a single PCB, the connection length for the relatively high power supply and the heating chamber can be reduced, and the heating chamber can transfer power intended for other lower power components to locations within the PCB away from the high-power connections.
[0013] Optionally, on the surface of the first PCB, a first electrical contact for the power supply is adjacent to a first electrical contact for the heating chamber, and a second electrical contact for the power supply is adjacent to a second electrical contact for the heating chamber. By arranging the first and second terminals for the heating chamber next to the first and second terminals for the power supply, respectively, the distance for high power transmission within the first PCB can be reduced, which reduces heat dissipation within the first PCB.
[0014] Optionally, the first PCB is a double-sided PCB, with the electrical contacts for connecting to the power supply arranged on one side of the double-sided PCB and the electrical contacts for connecting to the heating chamber arranged on the other side of the double-sided PCB. With this arrangement, the wiring connections do not need to extend around the first PCB, and the first PCB can extend into the internal space of the housing, thereby dividing the internal space in two. The first part of the internal space contains the power supply, and the second part of the internal space contains the heating chamber.
[0015] Optionally, in the first PCB, the first electrical contact for the power supply is directly connected to the first electrical contact for the heating chamber, or the second electrical contact for the power supply is directly connected to the second electrical contact for the heating chamber. This arrangement reduces the number of individual electrical contacts required and simplifies the manufacturing of the first PCB.
[0016] Optionally, the first PCB is arranged as a thermal barrier between the heating chamber and the power supply. This arrangement makes it less likely that heat leaking from the heating chamber will reach the power supply, and reduces the maximum temperature of the power supply in use, thereby improving safety.
[0017] Optionally, the device further includes a heating chamber frame configured to support the heating chamber; and a power supply frame configured to support the power supply. By providing frames for each of the heating chamber and the power supply, the heating chamber and the power supply can be located in a fixed position within the device and prevented from moving within the device, thereby reducing the risk of damage to the device, such as from drops.
[0018] Alternatively, the first control circuit system is supported between the heating chamber frame and the power supply frame. This arrangement also positions the first control circuit system in a fixed location within the device without increasing complexity by adding a third frame feature.
[0019] Optionally, the device further includes a second control circuit system, wherein the first control circuit system is configured to support higher power than the second control circuit system, and the first control circuit system is configured to communicate with the second control circuit system using logic signaling. By providing different control circuit systems to support different power levels, components that do not need to carry power between the power source and the heating chamber can be constructed with less durable (and less expensive) materials compared to if all control circuit systems in the device used similar materials.
[0020] Optionally, the second control circuit system is configured to control the first control circuit system. With this configuration, all "intelligent" control circuit systems (such as logic processors) can be composed of relatively low-power circuits, while the controlled first control circuit system only provides basic power supply management and switching.
[0021] Optionally, the second control circuit system includes a second PCB. By providing the second PCB as part of the second control circuit system, the second control circuit system can be prepared as a single component, which can be easily assembled into the device.
[0022] Optionally, the second PCB is connected to the first PCB via a flexible PCB portion. With this arrangement, the complete control circuit system can be easily assembled into the device by bending the flexible PCB portion to achieve the desired positions of the first and second PCBs, and the electrical connection between the first and second PCBs is limited to a small volume.
[0023] Optionally, the second control circuit system is arranged side-by-side with the heating chamber. By arranging the heating chamber and the second control circuit system side-by-side, the risk of exposure to gases emitted from the power source is reduced.
[0024] Optionally, the heating chamber frame is arranged as a thermal barrier between the heating chamber and the second control circuit system. This arrangement reduces the maximum temperature of the second control circuit system in use, and the second control circuit system can be constructed of a material with a lower temperature tolerance.
[0025] According to a second aspect, this disclosure provides a control circuit system for an aerosol generating apparatus, the aerosol generating apparatus including a power supply and a heating chamber operable to heat an aerosol matrix to generate an aerosol, the control circuit system including: a first PCB configured to control the power supply from the power supply to the heating chamber, wherein the first PCB includes electrical contacts for connection to the power supply and electrical contacts for connection to the heating chamber; and a second PCB, wherein the first PCB is configured to support higher power than the second PCB, and the first PCB is configured to communicate with the second PCB using logic signaling.
[0026] Optionally, the second PCB is connected to the first PCB via a flexible PCB portion.
[0027] Optionally, the first PCB is a double-sided PCB, which includes contacts on both sides.
[0028] Optionally, the second PCB includes a main logic board configured to perform central control over the remaining control circuitry system.
[0029] Optionally, the control circuit system includes a third PCB, which is a user interface board.
[0030] Optionally, the control circuit system includes a fourth PCB, which includes a charging board through which power can be supplied to recharge the power source.
[0031] Optionally, the control circuit system includes a fifth PCB, which includes a Hall sensor.
[0032] Optionally, the second PCB is connected to the first, third, fourth, and fifth PCBs via flexible portions.
[0033] In aerosol generating devices, the power supplied from the power source to the heating element (such as the heating chamber) is much greater than the power used for other circuits (such as the user interface and timing circuits). By providing a control circuit system in the form of a high-power PCB configured to transfer power between the power source and the heating chamber, and a low-power PCB configured to communicate with the high-power PCB using logic signaling, the size of the PCB for controlling the power can be minimized, and the path length (and resistive losses) for driving the heating chamber can be minimized, while also providing PCB space that can be used for low-power systems (such as a processor for logic control of the aerosol generating device).

[0039] Figure 6A and Figure 6B This is a schematic representation of the first and second sides of the control circuit system of the aerosol generating device. Detailed Implementation
[0040] Figure 1 This is a schematic illustration of the aerosol generating apparatus 1 according to the present invention.
[0041] The device 1 includes a power supply 11, a heating chamber 12, and a control circuit system 13, all of which are arranged within the internal volume of the housing 14.
[0042] The power source 11 can be, for example, a battery, such as a dry cell battery or a pouch cell.
[0043] The heating chamber 12 is a chamber with a heater operable to supply heat to the chamber to heat the aerosol matrix therein and generate aerosols. For example, the heating chamber 12 may include a cylindrical wall of ceramic or metal, open at one end and surrounded by an insulator. The open end of the heating chamber 12 is preferably oriented in the same direction as the mouth end 141 of the housing. In other embodiments, the device 1 may include conduits to transfer the generated aerosols from the heating chamber 12 to the mouth end 141 of the housing. The heating chamber 12 receives electrical power to drive the heater. For example, the heater may be a resistance heater, such as a resistance rail attached to or located inside or around the chamber wall, or a blade heater protruding into the chamber and operable to penetrate into the aerosol matrix.
[0044] The control circuitry 13 is configured to control the power supply from the heating chamber. The control circuitry can be as simple as a user-operated manual switch. However, it is preferably complex enough to regulate the power supply to provide the desired heating rate in the heating chamber, for example, by using buffers, boost converters, and / or amplifiers. The control circuitry can also perform other functions, such as sensing the charging status of the power source 11; recharging the power source 11; providing automatic control of the heating chamber 12 to provide a predetermined amount or intensity of aerosol based on user input; and controlling output elements (such as LEDs) to indicate the status of the device. Each of the heating chamber 12 and the power source 11 can be directly connected to the control circuitry 13, or they can be connected via wires and / or rigid connectors. The connectors can, for example, comprise steel, nickel, or nickel-plated steel.
[0045] The housing 14 includes a mouthpiece 141 at which the generated aerosol is provided for inhalation by a user. For example, the mouthpiece 141 may include an opening and a cap. The cap may be, for example, as shown below. Figure 1 The illustrated cover is a hinged cover, a removable cover, or a sliding cover. In other embodiments, the nozzle end 141 may be open to allow aerosol to exit the device 1.
[0046] The housing 14 also includes an opposite end 142, opposite to the mouth end 141. For example... Figure 1 As shown, the housing 14 can be relatively long and narrow between the mouth end 141 and the opposite end 142. With this shape, the user can easily hold the device 1 on the long and narrow sides to place the aerosol matrix into the heating chamber 12 via the mouth end 141, or to bring the mouth end 141 into the user's mouth to inhale the aerosol generated in the heating chamber 12 via the mouth end 141.
[0047] To illustrate the internal components of device 1, in Figure 1 The housing 14 is shown as transparent. In some embodiments, the housing 14 may be transparent, but this is not necessary. In fact, in a preferred embodiment, for robustness, the housing 14 comprises a metal (such as aluminum), and therefore the housing is not transparent. The outer surface of the housing 14 may be partially or completely covered by a heat insulation material (such as a polymer grip) so that the user can hold the device 1 even if some of the heat from the heating chamber 12 is dissipated within the housing 14.
[0048] Figure 2 This is a schematic representation of the first part of the aerosol generating apparatus in its assembled state. This is only a partial representation of apparatus 1 and does not necessarily represent all stages in the methods of assembling apparatus 1.
[0049] like Figure 2As shown in the embodiment of the accompanying drawings, the power supply frame 15 supports the power supply 11 in a fixed position within a portion of the housing 14 facing opposite ends 142. The power supply frame 15 is preferably made of an insulating material such as PEEK (polyetheretherketone).
[0050] The power supply frame 15 includes an opening 151 through which an electrical connection to the power supply 11 can extend. In addition to the opening 151, the power supply frame 15 is preferably fitted tightly against the inner surface of the housing 14, such that the power supply 11 is largely shielded from heat in the portion of the housing 14 facing the mouth end 141 by the power supply frame 15.
[0051] Figure 3A This is a schematic representation of the second part of the aerosol generating apparatus in its assembled state. Again, these are only a partial representation of apparatus 1 and not necessarily all stages in the methods of assembling apparatus 1.
[0052] like Figure 3A As shown, the first control circuit system 131 of the control circuit system 13 is the first PCB. By... Figure 3A and Figure 1 By comparison, it can be seen that the first PCB is arranged in a plane transverse to the "length" direction of the housing 14, between the opening end 141 and the opposite end 142. In this position, the first PCB serves as a thermal barrier between the heating chamber 12 and the power supply 11. The first PCB 131 can be arranged together with the power supply frame 15 to provide a complete barrier inside the housing 14. Additionally, in Figure 3A In the partially assembled state shown, the connector to the first PCB 131 can be easily soldered to the side of the first PCB 131 facing the mouth end.
[0053] exist Figure 3B The complete barrier can be seen further in the image, which is a cross-section of device 1. Figure 3B The image shows a first PCB 131 supported between a power supply frame 15 and a heating chamber frame 16. The heating chamber frame 16 supports the heating chamber 12 in a fixed position within the housing 14. The heating chamber frame 16 is preferably made of an insulating material such as PEEK (polyetheretherketone).
[0054] The heating chamber 12 is arranged between the first control circuit system 131 of the control circuit system 13 and the mouth end 141 via the power supply frame 15 and the heating chamber frame 16, and the first control circuit system 131 is arranged between the heating chamber 12 and the power supply 11.
[0055] Preferably, the mouth end 141, the heating chamber 12, the first control circuit system 131, and the power supply 11 are arranged along a common line between the mouth end 141 and the opposite end 142. With this arrangement, the device 1 has a linear configuration that can be made as narrow as possible and easy to hold.
[0056] Figure 4A and Figure 4B This is a schematic representation of the third part of the aerosol generating apparatus in its assembled state. Similarly, these are only a partial representation of apparatus 1 and not necessarily all stages in the methods of assembling apparatus 1.
[0057] In its third assembled state, device 1 also includes a heating chamber frame 16, a second control circuit system 132, and a third control circuit system 133. For example... Figure 4A and 4B As shown, each of the second control circuit system 132 and the third control circuit system 133 can be in the form of a PCB.
[0058] Similar to the power supply frame 15, in the embodiment shown in the figures, the heating chamber frame 16 has an opening through which an electrical connection to the power supply 11 can extend, for example, from the first control circuitry 131.
[0059] The heating chamber frame 16 may be an extension of the power supply frame 15, and frames 15 and 16 may be molded as a single component. In this embodiment, the opening in the power supply frame portion 15 or the heating chamber frame portion 16 may be large enough to add the first PCB 131 in its assembly location, or the individual frames 15, 16 may include side slots for positioning the first PCB 131. Connections to the heating chamber 12 and the power supply 11 may be added before or after the first PCB is placed within the individual frames 15, 16.
[0060] In the embodiment shown in the figures, the second control circuitry 132 is configured to support lower power than the first control circuitry 131, and the first control circuitry 131 is configured to communicate with the second control circuitry 132 using logic signaling. More specifically, while the first control circuitry 131 is configured to supply power to the heating chamber, the second control circuitry 132 does not carry a significant amount of power, but only uses power to drive logic circuitry such as processors and memory. Adjustments to carry a larger amount of power may include thicker wiring, wider PCB circuit traces, the inclusion of heat sinks, and other techniques known to those skilled in the art. Furthermore, given the aforementioned secondary function of the first PCB 131 as a heat shield, the first PCB may be thicker than the corresponding second PCB 132 to provide improved thermal insulation.
[0061] The second control circuit system 132 can be configured to control the first control circuit system 131. The advantage of this is that all logic control can be moved to the second control circuit system 132, while the first control circuit system 131 only needs to handle the actual power flow between the power supply 11 and the heating chamber 12. In many embodiments, the first control circuit system 131 also provides power to other components of the control circuit system 13, which can be diverted from the power supply to the heating chamber 12.
[0062] The second control circuit system 132 is arranged side by side with the heating chamber 12. More specifically, in the embodiment shown in the figures, the second control circuit system 132 is arranged side by side with the heating chamber frame 16, such that the heating chamber frame 16 serves as a thermal barrier between the heating chamber 12 and the second control circuit system 132.
[0063] Figure 5 This is a schematic representation of the fourth assembled state of the aerosol generating device 1. Compared to the third assembled state, the device 1 also includes a heating chamber 12. Figure 5 The common line L is shown, along which the heating chamber 12, the first control circuit system 131, and the power supply 11 are all arranged. According to... Figure 1 In the fully assembled device of the embodiment, the mouth end 141 is also arranged on the common line L.
[0064] Figure 6A and Figure 6B This is a schematic representation of the first and second sides of the control circuit system of the aerosol generating device. Figure 6A and Figure 6B An example of a form is also shown in which the control circuitry system for the aerosol generating device can be distributed independently.
[0065] like Figure 6A and 6B As shown in the embodiment of the accompanying drawings, the control circuit system 13 includes a first PCB 131, a second PCB 132, a third PCB 133, a fourth PCB 134, and a fifth PCB 135. All five PCBs are connected together via a flexible PCB portion 136, which neatly incorporates electrical connections and is pre-printed, allowing for easy assembly and folding for mounting within the housing 14. Alternatively, any pair of PCBs can be connected, for example, by wires or tabs soldered to each board, or by spring contacts and / or card / slot connectors.
[0066] As described above, the first PCB 131 is a power distribution board used to supply power to the heating chamber 12 and to supply power (in a small amount) to the remaining control circuitry system 13. (Refer to...) Figure 6BThe first PCB 131 includes an electrical contact 137 for connection to a power supply 11 and an electrical contact 138 for connection to a heating chamber.
[0067] More specifically, in the embodiment shown in the drawings, the first electrical contact 137 for the power supply 11 is adjacent to the first electrical contact 138 for the heating chamber 12, and the second electrical contact 137 for the power supply 11 is adjacent to the second electrical contact 138 for the heating chamber 12. Figure 6B As shown, the four contacts 137 and 138 can be arranged in a row. The advantage of this arrangement is that it reduces the electrical path length within the first PCB 131 that supplies power to the heating chamber 12, thereby reducing the heat dissipated in the first PCB 131.
[0068] In an alternative embodiment, the first electrical contact 137 for the power supply 11 can be directly connected to the first electrical contact 138 for the heating chamber 12. The effect of this is that only one terminal of the power supply from the power supply 11 to the heating chamber 12 is switchable, but the structure is simplified by allowing the electrical contacts to be combined into only three different contacts on the first PCB 131.
[0069] In another alternative embodiment, the first PCB 131 is a double-sided PCB, which has two sides (e.g., Figure 6A The visible side and Figure 6B Both sides (visible side) include contacts. Electrical contacts 137 for the power supply 11 can be arranged on the opposite side of the first PCB 131 facing the opposite end 142, and electrical contacts 138 for the power supply 11 can be arranged on the other side of the first PCB 131 facing the mouth end 141. This arrangement eliminates the need for connectors to extend between the first PCB 131 and the power supply frame 15, meaning that the first PCB 131 and the power supply frame 15 can provide a more effective thermal barrier.
[0070] In the embodiment shown in the accompanying drawings, the second PCB 132 is the main logic board that performs central control over the remaining control circuitry system 13. For example... Figure 6A As shown, the second PCB also includes electrical contacts for one or more temperature sensors arranged to sense the temperature of the power supply 11 or the heating chamber 12.
[0071] The third PCB 133 is a user interface board that includes one or more buttons, sliders, and lights or other input / output components to provide a user interface through which a user can control the device 1 and understand the status of the device 1. The contacts on the second PCB 132 can also be connected to one or more other I / O components, such as haptic feedback elements (e.g., vibrators).
[0072] The fourth PCB 134 is a charging board through which power can be supplied to recharge the power supply 11. In the embodiment shown in the figures, the fourth PCB 134 is connected to the second PCB 132, and the power for recharging the power supply 11 passes through the main logic board. In other embodiments, the fourth PCB 134 may be additionally or alternatively connected to the first PCB 131 or directly connected to the power supply 11, thereby separating the recharging power from the logic circuitry of the second PCB 132.
[0073] The fifth PCB 135 in this embodiment is a Hall sensor board. The Hall sensor board is used in conjunction with a magnet in the cover at the mouth end 141 of the housing 14 to detect the open or closed state of the mouth end 141. In many embodiments where detecting this open or closed state is not required, the fifth PCB 135 can be omitted.
[0074] The above-described arrangement of the heating chamber 12, the first control circuit system 131, and the power supply 11 can be achieved without the need for the insulating frames 15 and 16. For example, the inner surface of the housing 14 can be adapted to align the heating chamber 12, the first control circuit system 131, and the power supply 11 when inserted into the housing 14 to assemble the device 1. In this embodiment, the first control circuit system 131 can be loose between the heating chamber 12 and the power supply 11, or it can be held in a fixed position by some combination of the heating chamber 12, the power supply 11, and the housing 14. One embodiment is similar to the embodiment described above with reference to the accompanying drawings, except that the frames 15 and 16 are omitted.
[0075] Furthermore, the first PCB 131 may not be arranged laterally between the power supply 11 and the heating chamber 12. Even if the first PCB 131 is arranged differently, its presence between the power supply 11 and the heating chamber 12 means that the electrical path from the power supply 11 and the heating chamber 12 can be shortened, although the first PCB may not be as effective as a thermal barrier in other arrangements.
[0076] Additionally, in some embodiments, the control circuitry 13 can be provided without using one or more PCBs. For example, the first control circuitry 131 may consist only of a mechanical switch, wherein a control arm extends between the exterior of the housing 14 and a set of electrical contacts located between the heating chamber 12 and the power supply 11. Other circuit components may be connected via wires instead of printed circuits. Even in these embodiments, the control circuitry 13 is arranged such that the electrical path from the power supply 12 to the heating chamber 11 is shortened and resistive losses in the electrical path are reduced.
[0077] In the above embodiments, the control circuit system 13 includes multiple parts (first control circuit system 131, second control circuit system 132, etc.). In other embodiments, such as in the aforementioned case where the control circuit system 13 consists of a simple switch, the second control circuit system 132, etc., can be omitted. One embodiment is similar to the embodiment described with reference to the accompanying drawings, but the second, third, fourth, and fifth control circuits 132-135 (second to fifth PCBs) and the flexible PCB portion 136 are omitted.
