Description

AN AEROSOL GENERATING DEVICE WITH A REMOVABLE HEATERTECHNICAL FIELD

[0001] The present disclosure relates to the field of aerosol generating devices. More particularly, the present disclosure relates to an aerosol generating device with a removable (also referred to as detachable) periphery heater that allows for easy removal of the periphery heater facilitating residue removal and cleaning of the aerosol generating device.BACKGROUND

[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced as prior art.

[0003] Aerosol generating devices utilize a variety of heating methods to aerosolize aerosol generating substrate contained within compatible aerosol generating articles, to produce a consumable aerosol for inhalation. Since, surface of the aerosol generating article remains in contact with a heating element, charred particles often stuck in a heating cavity, and condensate gets deposited on the heating element during heating. The small size of the heating cavity, makes it difficult for the users to clean the aerosol generating device. This is particularly problematic in devices with a periphery heater arrangement, where small diameter of the cavity complicates cleaning. This often leads to malfunctioning of the device, which is undesirable for the users and negatively impacts usability of the aerosol generating device.

[0004] A patent document WO2022145778A1 titled, “Aerosol generating device and operating method thereof’ describes a main body including a controller and a battery, and a removable heater module removably combined to the main body. The removable heater module is configured to heat an aerosol generating article, and includes a heater and a first memory. The first memory stores heater module information about intrinsic properties of the removable heater module. The heater module information being obtained during a manufacturing process of the removable heater module. The controller is configured to obtain the heater module information from the first memory when the removable heater is combined to the main body, determine a control condition corresponding to the removable heater module by using the obtained heater module information, and control the aerosol generating device based on the determined control condition.

[0005] Another patent document CN218682055U titled, “Aerosol forming device” describes an aerosol forming device including a control panel, a casing, and a heating component detachably connected to the casing. Further, the heating component includes a heating body arranged in the casing. The heating body has a heating chamber for accommodating an aerosol generating substrate, and the heating body is used for passing through heat transfer heating the aerosol generating substrate, where when the heating component is installed in a housing, the heating body is electrically connected to a control board, and when the heating component is separated from the housing, the heating body is connected to the electrical connection to the control board is broken. The device can use either electromagnetic induction or resistance heating to generate heat.

[0006] Yet another patent document US2021112878A1 titled, “Aerosol-generating device with a removably-insertable residue collector” describes an aerosol generating device having a heating chamber configured to heat an aerosol-forming substrate. The heating chamber including a first end having an opening, a second end having a base, and a side wall extending between the opening and the base, and a residue collector removably-insertable into the heating chamber and positionable at or near the second end. Further, the heating chamber includes a first side opening in the side wall, and a second side opening in the side wall, opposite the first side opening, and where the residue collector is insertable into the heating chamber and removable from the heating chamber through the first and second side openings.

[0007] Yet still another patent document W02020025637A1 titled, “An Extractor for an aerosol-generating device” describes an extractor for extracting an aerosol generating article received in an aerosol generating device. The extractor includes a body defining a cavity for receiving the aerosol generating article, and a resilient coupling element attached to the body of the extractor, where the resilient coupling element is movable independent of the body of the extractor to releasably couple the extractor to a portion of the aerosol generating device. Additionally, the aerosol generating device includes a heater casing and a mouthpiece, with the extractor facilitating removal of the aerosol generating article after use.

[0008] Thus, although the above referred documents describe the aerosol generating devices with removable components to facilitate stick removal or replaceable heater designs, these devices are susceptible to damage due to repeated movement of mechanical components. In particular, for the periphery heaters, if the aerosol generating article is stuck in the heater cavity, it is very difficult to remove the residue. Further, arrangements for stick removal are not well documented for the periphery heater.

[0009] Thus, there arises a need for modification in design of the device to address the above said issues.

[0010] There is therefore a need in the art to develop a unique and easy to manufacture aerosol generating device with a detachable periphery heater and aerosol generating article remover that allows for easy removal of the heater for aerosol generating article residue removal and cleaning of the aerosol generating device.OBJECTS OF THE PRESENT DISCLOSURE

Additionally, it is intended that such equivalents include both currently known equivalents as well as equivalents developed in the future (i.e., any elements developed that perform the same function, regardless of structure).

[0055] The present disclosure relates to the field of aerosol generating devices. More particularly, the present disclosure relates to an aerosol generating device with a detachable periphery heater (referred simply as “heater” herein) and aerosol generating article remover assembly that allows for easy removal of the heater for ease of article residue removal and cleaning of the aerosol generating device.

[0056] Existing electronic aerosol generating devices encounter several significant drawbacks, primarily due to their compact design and operation at lower temperatures. The close contact between the heating element and the aerosol generating article leads to the accumulation of charred particles and condensate in the small heating cavity, complicating cleaning efforts, particularly in devices with a peripheral heater and aerosol generating article remover arrangement. This buildup not only causes inconsistent heating and diminished vapor quality but also results in increased wear on components, reducing the device's longevity.

[0057] To address the aforesaid issue, the proposed aerosol generating device have been developed with a detachable periphery heater which also works as aerosol generating articleremover, aiming to enable easy and efficient removal of aerosol generating article stuck within a heating cavity, thereby reducing maintenance time and enhancing user satisfaction.

[0058] FIGs. 1A-1C illustrate exemplary sectional views of a main body, a cap assembly, and an aerosol generating device including the main body and the cap assembly, in accordance with a first embodiment of the present disclosure.

[0059] Referring to FIGs. 1A-1C and according to an aspect of the present disclosure, the proposed aerosol generating device 100 includes a main body 102, and a cap assembly 104 comprising a cap body 104’ removably coupled to the main body 102. A top portion 104’ -1 of the cap body 104’ embeds a heater section that surrounds a receiving cavity 114 of the main body 102, while a bottom portion 104 ’-2 of the cap body 104’ has a skeleton structure with an opening for allowing air through the aerosol generating article 118. Upon placement of the cap assembly 104 in a heating cavity 122 of the main body 102, a first set of contact terminals of the main body 102 align with a second set of contact terminals 116 of the cap assembly 104 to facilitate electrical supply (or power) to at least one heater (simply referred to as “heater” hereinafter) positioned in the heating section of the cap body 104’ by establishing an electrical connection. Upon establishment of the electrical connection, an aerosol generating article 118 is secured in the receiving cavity 114 of the cap assembly 104, such that the aerosol generating article 118 is circumferentially surrounded by the heater to produce an aerosol.

[0060] The main body 102 can include a power source 106, and a controller 108 having the first set of contact terminals 110. The cap assembly 104 can include a periphery heater 112 as the heater, the receiving cavity 114 configured to receive the aerosol generating article 118, and the second set of contact terminals 116-1, 116-2 (collectively referred as 116 hereinafter) configured at an extended portion of the cap body 104’ of the cap assembly 104. Upon placement of the cap assembly 104 in the heating cavity 122 provided in the main body 102, the second set of contact terminals 116 of the cap assembly 104 align with the first set of contact terminals 110-1, 110-2 (collectively referred as 110 hereinafter) of the controller 108 (present in the main body 102) to facilitate power to the periphery heater 112. Once the electrical connection is established, the electrical supply can be transferred to the periphery heater 112, the aerosol generating article 118 is securely placed within the receiving cavity 114 of the cap assembly 104 for aerosolization. In an embodiment, the aerosol generating article 118 can be in form selected from but not limited to a group consisting of: film, mats, flakes, cut rag, or recon materials.

[0061] In an embodiment, the main body 102 can include the power source 106 operatively coupled to the heater. The power source 106 can be a battery. The battery provides an electriccurrent required to the at least one heating element (simply referred as “heating element” herein) including the periphery heater 112 and aerosolize the aerosol generating article 118. In another embodiment, the cap assembly 104 can be connected to the power source 106 through alignment of the first set of contact terminals 110 on the main body 102 with the second set of contact terminals 116 on the cap body 104’. Upon actuation of the aerosol generating device 100, the power source 106 can transmit the electric current through the heating element of the periphery heater 112 to generate heat.

[0062] In an implementation, during heating of the aerosol generating article 118 by the heater, one or more segments of the aerosol generating article 118 get stuck in the receiving cavity 114 of the cap assembly 104 and / or in the heating cavity 122 of the main body 102. The stuck segments of the aerosol generating article 118 can act as residual particles, which can be removed by detaching the cap assembly 104 acting as a residue remover, from the main body 102 of the aerosol generating device 100, and thereafter cleaning the receiving cavity 114 of the cap assembly 104 and / or in the heating cavity 122 of the main body 102 manually.

[0063] In an embodiment, the main body 102 can include the controller 108 operatively coupled to the power source 106. The controller 108 can be configured with the first set of contact terminals 110. The electrical connection between the first and second sets of contact terminals 110, 116, respectively can cause the controller 108 to enable the electrical supply from the power source 106 to the heater. The controller 108 can include one or more processors (interchangeably referred to as processor, hereinafter). The processor can be implemented as one or more microprocessors, microcomputers, microcontrollers, edge or fog microcontrollers, digital signal processors, central processing units, logic circuitries, and / or any devices that process data based on operational instructions. Among other capabilities, the processor can be configured to fetch and execute computer-readable instructions stored in a memory of the device 100. The memory can be configured to store one or more computer-readable instructions or routines in a non-transitory computer readable storage medium, which may be fetched and executed to actuate the heater.

[0064] In an embodiment, the memory can comprise any non-transitory storage device including, for example, volatile memory such as Random-Access Memory (RAM), or nonvolatile memory such as Erasable Programmable Read-Only Memory (EPROM), flash memory, and the like.

[0065] In an embodiment, the cap assembly 104 can include the periphery heater 112. The periphery heater 112 can be configured to heat sides of the aerosol generating article 118, upon receiving the electrical supply from the power source 106. In one of the embodiments, theperiphery heater 112 can be the heater as shown in FIG. 1C. The periphery heater 112 often has a cylindrical or tubular shape, allowing it to surround or enclose the aerosol generating article 118, thereby facilitating even heat distribution around the aerosol generating article 118. When the current flows through the heating element, it generates heat, which can be then transferred to the aerosol generating article 118. In an embodiment, the periphery heater 112 can include a heater lining 120 that can facilitate thermal insulation to minimize heat loss to an environment and protect the user from bums. The heater lining 120 can be paced directly around the heating elements, forming a protective layer between the heating element and the environment. In an implementation, placement of the heater lining 120 adjacent to the heating elements can minimize air gap between them, thus help in enhancing conduction process, and allowing the heat to flow rapidly from the heating element to the heater lining 120. When the heating element can be energized by the current transmitted by the power source 106, it can generate the heat. This heat can be transferred to the heater lining 120 via conduction process. As the heater lining 120 heats up, it can transfer the heat to the aerosol generating article 118, thereby raising its temperature to a point of vaporization to generate an aerosol. In an embodiment, the periphery heater 112 can use various method of heating such as resistive heating, Infrared (IR) heating and inductive heating.

[0066] In an embodiment, the heater lining 120 can be made from materials having good thermal conductivity such as but not limited to metals, silicone, ceramic composites, and the like.

[0067] In an embodiment, the cap assembly 104 can include the receiving cavity 114 configured to securely accommodate the aerosol generating article 118 for aerosolization. The receiving cavity 114 can be a cylindrical cavity surrounded by the periphery heater 112. In some embodiment, the periphery heater 112 can be made of Positive Temperature Coefficient (PTC) element to monitor temperature of the aerosol generating article 118 during operation. The PTC heating element is an electrical resistance heater whose resistance increases significantly with temperature, enabling user to monitor temperature without using any sensor.

[0068] In an embodiment, the first set of contact terminals 110 can include a first pair of contact terminals 110-1, 110-2 (collectively referred as “110” herein) on the main body 102 (Refer FIG. 5 A) positioned diagonally opposite to each other. The second set of contact terminals 116 can include a second pair of contact terminals 116-1, 116-2 (collectively referred as “116” herein) on the cap body 104’ (Refer FIG. 5B) positioned diagonally opposite to each other, such that the pair of first contact terminals 110 and the pair of second contact terminals 116remain in line to establish the electrical connection, upon attachment of the cap assembly 104 with the main body 102, regardless of their orientation direction.

[0069] In an embodiment, the cap assembly 104 can be detachably coupled to the main body 102 via a connecting mechanism. The connection mechanism can include one or more of: a magnetic coupling or a mechanical coupling 600 (Refer FIGs. 6A-6C). The magnetic coupling can be configured to facilitate better and consistent connection the first and second set of contact terminals 110, 116. The magnetic coupling can include a first set of magnetic magnets positioned on the main body 102, and a second set of magnetic members positioned on the cap body 104’, where placement of the cap assembly 104 at a pre-defined position from the main body 102, can magnetically engage the first set of magnetic members with the second set of magnetic members, which correspondingly can cause the cap assembly 104 to be axially pulled towards and secured to the main body 102, and electrically connect the first and second set of contact terminals 110, 116. The magnetic engagement of the first and second sets of magnetic magnets can facilitate in alignment and engagement of the first and second sets of contact terminals 110, 116, thereby operably connecting the heater to the power source 106. Each of the first and second sets of magnetic members may include any of, but not limited to: magnets, magnetic elements, ferromagnetic metals or combination thereof.

[0070] Additionally, the controller 108 can be programmed so that the power source 106 will not supply power to the heater unless a connection between the cap assembly 104 and main body 102 is established. Thus, in case of loss in electrical connection between the first and second sets of contact terminals 110, 116, the controller 108 can halt the electrical supply from the power source 106 to the heater.

[0071] FIGs. 2A-2C illustrate exemplary sectional views of the main body, the cap assembly, and an aerosol generating device including the main body, and the cap assembly, showing at least one opening to secure a core heater, in accordance with a second embodiment of the present disclosure.

[0072] Referring to FIGs. 2A-2C and according to a second embodiment, the aerosol generating device 100 can include a second heater as a core heater 204 in conjunction with the periphery heater 112 to allow rapid and uniform heating through the aerosol generating article 118. The core heater 204 can be affixed into at least one opening 202 (simply referred to as “opening 202” hereinafter) configured at a bottom surface of the cap assembly 104. The core heater 204 can heat- up a center of the aerosol generating article 118. By having both the heaters 112, 204 in the aerosol generating device 100, the device 100 can deliver the heat to the aerosol generating article 118 through multiple directions. This dual heating strategy can minimizetemperature gradients within the aerosol generating article 118, ensuring all portions can reach desired vaporization temperature efficiently.

[0073] As can be appreciated, heating from both the peripheral and core heaters 112, 204 can ensure that the aerosol generating article 118 can achieve uniform temperature distribution which is essential for effective aerosolization.

[0074] FIGs. 3A-3C illustrate exemplary sectional views of the main body, the cap assembly, and the aerosol generating device including the main body and the cap assembly, showing a plurality of side cut-outs, in accordance with a third embodiment of the present disclosure.

[0075] Referring to FIGs. 3A-3C and according to a third embodiment, the periphery heater 112 can include a plurality of side cut-outs 302 (collectively referred as “side cut-outs 302” hereinafter) configured circumferentially on the bottom surface, and elongated along a longitudinal axis of the periphery heater 112. The side cut-outs 302 can be configured to facilitate and direct airflow towards the aerosol generating article 118. By facilitating improved airflow, the side cut-outs 302 can significantly reduce a pressure drop experienced by the user during inhalation, leading to a better user experience. In addition, the combined effect of improved airflow and reduced pressure drop can lead to an enhanced overall experience.

[0076] The side cut-outs 302 can allow ambient air to enter the cap assembly 104 from multiple entry points, creating a pathway for air to flow directly towards the aerosol generating article 118. During inhalation, the user often experiences a pressure drop, which can make it more difficult to draw the aerosol. The presence of the side cut-outs 302 can help in solving this issue by allowing a smoother and more consistent airflow. As can be appreciated that by facilitating better airflow through the side cut-outs 302, the device 100 reduces the resistance the user encounters while inhaling. This results in a more comfortable and effective inhaling experience, as the user can inhale more easily and consistently.

[0077] FIGs. 4A-4C illustrate exemplary sectional views of the main body, the cap assembly, and the aerosol generating device including the main body and the cap assembly, showing the plurality of side cut-outs and the core heater in conjunction with the periphery heater, in accordance with a fourth embodiment of the present disclosure.
