Description

[0001] AEROSOL GENERATING DEVICE WITH DETACHABLE POWER SOURCE

[0002] TECHNICAL FIELD

[0003] The present disclosure relates generally to an aerosol generating device. More specifically, the present disclosure relates to an aerosol generating device with a detachable power source.

[0004] BACKGROUND

[0005] An aerosol-generating device is responsible for producing aerosol by heating an aerosolgenerating substrate contained within an aerosol-generating article. Instead of burning or combustion, the device heats the substrate to produce aerosol for inhalation during a vaping session. This alternative method of using tobacco products has gained popularity in recent years compared to traditional practices.

[0006] Various techniques are employed to increase the number of vaping sessions per charge of the aerosol-generating device. For example, the power capacity of the device’s battery can be increased. The battery is designed to accommodate more battery cells, resulting in more vaping sessions per charge. However, malfunctioning of any of the battery cells may lead to the malfunctioning of the entire battery.

[0007] Regulations concerning batteries and waste batteries state that batteries must be readily removable and replaceable by the end-user or by independent operators during an appliance’s lifetime. Aerosol-generating devices also fall under these regulations. However, in most traditional aerosol-generating devices, batteries are embedded within the device. These devices are designed such that the battery is fully embedded within the center of the respective aerosol-generating device. In such designs, if any battery cell malfunctions, the entire battery must be retrieved from the device, complicating the process. As the battery is traditionally embedded within the center of the device, retrieving it may require the removal of several other components. This may necessitate the removal of permanently soldered electrical connections, increasing the cost and size of the device. Moreover, the removal of these connections may result in additional faults within the device. Furthermore, providing access to the internal structure of the device can introduce moisture or dirt, potentially harming the device’s performance and creating new safety challenges.

[0008] Having a replaceable battery offers a technique to replace the battery module without direct exposure to other components. However, the replaceable battery module generally results in an increase in the size and cost of the aerosol-generating device. Additionally, the overall longevity and performance of the battery present further issues to address.

[0009] In light of the above discussion, there is a need for a smart aerosol generating device that may overcome the above-stated drawbacks. Further, multiple batteries may be attached to the aerosol generating device for delivering the required power output.

[0036] DETAILED DESCRIPTION OF EMBODIMENTS

[0037] The following detailed description illustrates embodiments of the present disclosure and ways in which they can be implemented. Although some modes of carrying out the present disclosure have been disclosed, those skilled in the art would recognize that other embodiments for carrying out or practicing the present disclosure are also possible.

[0038] In the description of the present invention, it should be understood that the orientation or positional relationship terms "one end", "another end", "the other end", "outside", "inside", "upper", "lower", "above", "top", "bottom", "horizontal", "coaxial", "central", "length", "distance", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description. Specifically, the orientation or positional relationship terms should be understood as the aerosol-generating device being in its upright position (top-down) and / or taking the centre of the opening of the heating chamber as the centre point or reference. Otherwise, the specific meanings of the above terms in the present invention should be understood according to specific situations that make the most technical sense for the skilled person in the art.

[0039] As an overview of an aerosol-generating device of an embodiment of the present invention, FIG. 1 illustrates an aerosol-generating device with some of its subassemblies. FIG. 2 to FIG. 9C show more details of some of the subassemblies. For ease of understanding and brevity, certain features shown in the drawings have not been described in detail and certain features have been omitted entirely. As used herein, the term "aerosol generation device", "E-cigarette" or "electronic cigarette" may include an electronic cigarette system configured to deliver an aerosol to a user, including an aerosol for smoking.

[0040] FIG. 1 illustrates an exemplary representation of an aerosol generating device 100, in accordance with an embodiment of the present disclosure. The aerosol generating device 100 includes two sections separable from each other - a first separable section 101 and a second separable section 106. The first separable section 101 and the second separable section 106 may be attached with each other through a holding arrangement 110.

[0041] The first separable section 101 includes a heater 102 and a primary battery 105. The heater 102 includes an opening 103 to receive an aerosol generating article 201 (as illustrated in FIG. 2). The opening 103 may be enclosed by a lid 103-1 to avoid ingress of dust therewithin. In an exemplary embodiment, the lid 103-1 may be hinged (not shown) to the opening 103. The lid 103-1 may be moved upwards to uncover the opening 103 and may be moved downwards to cover the opening 103. In another exemplary embodiment, the lid 103-1 may be slidably coupled to the opening 103. The lid 103-1 may be moved towards the opening 103 to cover the opening 103 (as shown in FIG. 1). Similarly, the lid 103-1 may be moved away from the opening 103 to uncover the opening 103 (as shown in FIG. 2). In an instance, the heater 102 may be configured to accommodate the aerosol generating article 201 in a vertical orientation along a longitudinal axis of the aerosol generating device 100. The aerosol generating article 201 may be a heated tobacco stick (HTS). The heater 102 may be made of a high temperature-resistant material such as stainless steel. As stainless steel has a low thermal conductivity, a coating may be applied to allow efficient spreading of the heat.

[0042] The primary battery 105 is configured to power the heater 102 by transmitting required electric supply to the heater 102. In an embodiment, the primary battery 105 may be a rechargeable battery, such as, but not limited to, a Lithium-ion battery, a Nickel-ion battery, or a Lead-acid battery. In another embodiment, the primary battery 105 may be a super capacitor, and may work based on the principle of electrostatic charge storage. The super capacitor may consist of two electrodes separated by an electrolyte. When a voltage is applied across the electrodes, positive and negative charges accumulate on surfaces of the electrodes, creating an electric double layer. The electric double layer may store electrical energy. While a traditional battery stores energy through chemical reactions, the supercapacitor stores energy through the physical separation of charges. This allows the supercapacitor to charge and discharge much faster than the traditional battery. Further, with respect to a traditional battery, the supercapacitor may have a longer lifespan, can be charged and discharged more times, and can operate in a wider temperature range.

[0043] Further, the first separable section 101 also includes a first printed circuit board assembly (PCBA) 104. The first PCBA 104 is electrically connected to the primary battery 105. In an embodiment, the first PCBA 104 may include an assembly of distinct electronic components on a printed circuit board (PCB). Such electronic components are not described here for the sake of brevity.

[0044] The second separable section 106 includes a secondary battery 107. In an embodiment, the second separable section 106 may be adapted to accommodate distinct sizes of the secondary battery 107. The secondary battery 107 may be a rechargeable battery. The user of the aerosol generating device 100 may pick a size of the secondary battery 107 that suits the requirements. A smaller secondary battery may result in a smaller size of the second separable section 106, resulting in reduction in size of the aerosol generating device 100. A large secondary batery may be required when a higher amount of power consumption is needed at a time-instant.

[0045] Further, the second separable section 106 includes a first auxiliary magnet 108 and a second auxiliary magnet 109. The first auxiliary magnet 108 is arranged closest to a top portion 114 of the secondary batery 107 and the second auxiliary magnet 109 is arranged closest to a botom portion 115 of the secondary batery 107. Further, a polarity of the first auxiliary magnet 108 is different from the polarity of the second auxiliary magnet 109. In an instance, if the polarity of the first auxiliary magnet 108 is North, then the polarity of the second auxiliary magnet 109 is South. In another instance, if the polarity of the first auxiliary magnet 108 is South, then the polarity of the second auxiliary magnet 109 is North. The first auxiliary magnet 108 and the second auxiliary magnet 109 are configured to create a magnetic field across the secondary batery 107. The created magnetic field may lead to an arrangement of ions within the secondary batery 107 in a specific manner, which results in improvement of conductivity of the ions as well as acceleration of flow and diffusion of the ions near electrodes associated with the secondary batery 107. This reduces internal resistance of the secondary batery 107, allowing for faster movement of the ions and resulting in a larger power output. As the ions move faster, reaction rate within the secondary battery 107 also increases resulting in rapid charging. In an instance, a smaller secondary battery may have reduced distance between the two magnets, i.e., the first auxiliary magnet 108 and the second auxiliary magnet 109. The reduced distance may result in enhancement of the magnet field across the secondary battery 107 between the two magnets and may further improve performance of the secondary batery 107. Further, an increase in thickness of both the magnets, i.e., the first auxiliary magnet 108 and the second auxiliary magnet 109, may also result in enhancement of the magnetic field across the secondary batery 107.

[0046] In an exemplary embodiment, each of the first auxiliary magnet 108 and the second auxiliary magnet 109 may include Neodymium Iron Boron (NdFeB) as NdFeB has high magnetic strength. NdFeB may be of any suitable grade such as N52, N50, N48, N45, or N42. Additionally, or alternatively, each of the first auxiliary magnet 108 and the second auxiliary magnet 109 may include Samarium Cobalt (SmCo) as SmCo has a high density and a high Curie temperature. Additionally, or alternatively, each of the first auxiliary magnet 108 and the second auxiliary magnet 109 may include alloys such as Aluminum- Nickel-Cobalt (Alnico), Ferrite, Ceramic, and the like.

[0047] The second separable section 106 further includes a second PCBA 113 which is is electrically connected to the secondary battery 107. In an embodiment, the second PCBA 113 may include an assembly of distinct electronic components on a PCB. The electronic components are not described here for the sake of brevity.

[0048] According to an embodiment, at least one of the first separable section 101 or the second separable section 106 includes the holding arrangement 110. The holding arrangement 110 is configured to detachably attach the first separable section 101 with the second separable section 106. In an exemplary embodiment, attachment of the first separable section 101 with the second separable section 106 may be such that the first separable section 101 is in a flush arrangement with the second separable section 106 on a side 116 that includes the holding arrangement 110. In another exemplary embodiment, the holding arrangement 110 may include a ferromagnetic material 112, which may be attached to a lower portion 117 of the first separable section 101 along a lateral direction (indicated by arrow 1-1’ in FIG. 2) of the first separable section 101. The ferromagnetic material 112 may be configured to magnetically couple with the first auxiliary magnet 108 along a longitudinal direction (indicated by arrow 2-2’) of the aerosol generating device 100, facilitating coupling between the first separable section 101 and the second separable section 106. By way of example, and not limitation, the ferromagnetic material 112 may include iron, nickel, and cobalt.

[0049] According to another embodiment, each of the first separable section 101 and the second separable section 106 includes an electrical connector 111-1 and 111-2, respectively. The attachment of the first separable section 101 with the second separable section 106 creates a contact between the electrical connector 111-1 of the first separable section 101 and the electrical connector 111-2 of the second separable section 106, causing the secondary battery 107 to supply power to the primary battery 105 or the heater 102. In an exemplary embodiment, the electrical connector 111-1 and the electrical connector 111-2 may include a Pogo pin or a pad interface. In another exemplary embodiment, the electrical connector 111-1 and the electrical connector 111-2 may also include other non-permanent connectors, such as wireless charging coils or a USB connection. FIG. 2 illustrates an exemplary diagram 200 representing detached first separable section 101 and second separable section 106 of the aerosol generating device 100 of FIG. 1, in accordance with an embodiment of the present disclosure. In the exemplary diagram 200, the first separable section 101 and the second separable section 106 are shown to be detached from one another. The aerosol generating article 201 is accommodated by the heater 102 in a vertical orientation along a longitudinal axis of the aerosol generating device 100. In an embodiment, the lid 103-1 may be moved to uncover the opening 103, and further the aerosol generating article 201 may be accommodated in the heater 102.

[0050] The aerosol generating device 100 includes a charging port 202, which may be adapted to connect a charger 203, for instance, a Universal Serial Bus (USB) charger, which is adapted to be connected to the second separable section 106 for facilitating charging. In an embodiment, the charging port 202 may not be directly connected to the secondary battery 107. Instead, the charging port 202 may be connected to the secondary battery 107 via the second PCBA 113. During operation, the charger 203 supplies electric power (from an external power source) to the second PCBA 113 through the charging port 202. The second PCBA 113 further facilitates transmission of the supplied electric power to the secondary battery 107. In some instances, the supplied electric power may be directly used for heating the aerosol generating article 201 by heating the heater 102.

[0051] According to another embodiment, the first auxiliary magnet 108 and the second auxiliary magnet 109 may create a magnetic field across the secondary battery 107, which may improve efficiency and longevity of the secondary battery 107. Moreover, the first separable section 101 and the second separable section 106 may be detachably attached with one another via the holding arrangement 110, such that the ferromagnetic material 112 magnetically couples with the first auxiliary magnet 108 along a first longitudinal direction (indicated by arrow 3-3’ in FIG. 3) of the aerosol generating device 100.

[0052] FIG. 3 illustrates an exemplary diagram 300 representing a first lateral connection between first separable section 101 and second separable section 106 of the aerosol generating device 100 of FIG. 1, in accordance with an embodiment of the present disclosure. As illustrated in the exemplary diagram 300, the holding arrangement 110 may include a pair of ferromagnetic materials, i.e., ferromagnetic material 112-1 and ferromagnetic material 112-2. The pair of ferromagnetic materials 112-1 and 112-2 may be attached to a side portion 302 of the first separable section 101 along the first longitudinal direction (indicated by the arrow 3-3’) of the first separable section 101. In an embodiment, the pair of ferromagnetic materials 112-1 and 112-2 may be positioned such that the pair of ferromagnetic materials 112-1 and 112-2 magnetically couples with the first auxiliary magnet 108 and the second auxiliary magnet 109 of the second separable section 106 respectively, along a lateral direction (not shown) of the aerosol generating device 100. The first auxiliary magnet 108 and the second auxiliary magnet 109 may be high-strength magnets. Further, magnetic coupling of each of the high- strength magnets of the second separable section 106 with the corresponding ferromagnetic materials 112-1 and 112-2 of the first separable section 101 (i.e., the magnetic coupling of the first auxiliary magnet 108 with the ferromagnetic material 112-

[0053] 1 and the magnetic coupling of the second auxiliary magnet 109 with the ferromagnetic material 112-1) leads to improvement in the performance of the secondary battery 107. The magnetic field may allow the first separable section 101 to be detachably attached with the second separable section 106. In another embodiment, the heater 102 may be positioned at a strategic position (not indicated) on the aerosol generating device 100, such that the heater 102 is far away from all the magnets - the first auxiliary magnet 108, the second auxiliary magnet 109, and the pair of ferromagnetic materials 112-1 and 112-

[0054] 2 in order to avoid demagnetisation of the magnets by the heater 102.

[0055] FIG. 4 illustrates an exemplary diagram 400 representing a second lateral connection between first separable section 101 and second separable section 106 of the aerosol generating device 100 of FIG. 1, in accordance with another embodiment of the present disclosure. As illustrated in the exemplary diagram 400, the holding arrangement 110 may include a ferromagnetic material 112 and a permanent magnet 401. In an embodiment, the ferromagnetic material 112 may be attached to a side portion 402 of the second separable section 106 along a second longitudinal direction of the second separable section 106. The second longitudinal direction is parallel to the first longitudinal direction (indicated by the arrow 3-3’ in FIG. 3) The permanent magnet 401 may be attached to a side portion 403 of the first separable section 101 along the first longitudinal direction (indicated by the arrow 3-3’ in FIG. 3) of the first separable section 101. Further, the permanent magnet 401 may be positioned in the first separable section 101, such that that the magnetic field created by the permanent magnet 401 has minimal effect on the primary battery 105. The permanent magnet 401 may neutralize the effect of the magnetic field created by the first auxiliary magnet 108 and the second auxiliary magnet 109 on the primary battery 105.

[0056] FIG. 5A illustrates an exemplary first diagram 500A that represents an interlocking mechanism 501 associated with the aerosol generating device 100 of FIG. 1, in accordance with another embodiment of the present disclosure. As illustrated in the first diagram 500A, the holding arrangement 110 may include an interlocking mechanism 501 attached to a side portion 502 of at least one of the first separable section 101 or the second separable section 106 along a longitudinal direction (indicated by the arrow 5-5’) of the aerosol generating device 100. As shown, for example, the interlocking mechanism 501 is a bayonet fitting.

In another embodiment, the interlocking mechanism 501 may also be positioned such that the interlocking mechanism 501 detachably attaches the first separable section 101 with the second separable section 106 along a lateral direction (not shown) of the aerosol generating device 100.

[0058] FIG. 6 illustrates an exemplary diagram 600 representing a configuration of the first separable section 101 of FIG. 1, in accordance with another embodiment of the present disclosure. As illustrated in the exemplary diagram 600, two magnets 601 and 602 are arranged at two distinct distal ends of the first separable section 101. The magnets 601 and 602 are arranged at either side of the primary battery 105 so that the magnetic field created in between the magnets 601 and 602 results in an improvement in overall performance of the primary battery 105. Further, the magnet 602 may be magnetically coupled with the first auxiliary magnet 108, facilitating detachable attachment between the first separable section 101 and the second separable section 106 in the longitudinal direction (indicated by the arrow 2-2’). In another case, the magnet 601 may be magnetically coupled with the first auxiliary magnet 108 and the magnet 602 may be magnetically coupled with the second auxiliary magnet 109, facilitating detachable attachment between the first separable section 101 and the second separable section 106 in the lateral direction (indicated by the arrow 1-1’).

[0059] In an embodiment, the magnet 601 and the magnet 602 are arranged such that a flat edge of the magnet 601 is parallel to the magnet 602. Further, the magnet 602 is circular in shape. In an embodiment, the first separable section 101 may be cylindrical in shape with a flat edge that is parallel to a flat edge of an exterior case of the aerosol generating device 100. The magnets 601 and 602 may be substituted by ferromagnetic materials which may lead to a reduction in the cost of the aerosol generating device 100.

[0060] In another embodiment, the magnet 601 may be configured at a distal end of the first PCBA 104 of the first separable section 101. Further, the magnet 601 may be configured below the bottom of the primary battery 105. Though only two magnets 601 and 602 are shown in FIG. 6, the number of connectors and magnets may be increased as per requirement for facilitating longitudinal or lateral orientation of the aerosol generating device 100, which is well within the scope of the present invention. The increase in the number of connectors and magnets leads to an improvement in usability of the aerosol generating device 100. Moreover, the increase in the number of connectors and magnets may also result in a reduction in cost of the aerosol generating device 100.

[0061] FIG. 7 illustrates an exemplary diagram 700 representing a configuration of the second separable section 106 of FIG. 1, in accordance with another embodiment of the present disclosure. As illustrated in the exemplary diagram 700, the first auxiliary magnet 108 is arranged proximal to the top portion 114 of the secondary battery 107 of the second separable section 106. The second auxiliary magnet 109 is arranged proximal to the bottom portion 115 of the secondary battery 107.
