[0037] Embodiments of the present invention will be described below for illustrative purposes only, with reference to the accompanying drawings. [Brief explanation of the drawing]

[0038] [Figure 1] This is a schematic front view of an aerosol supply device with a cover assembly. [Figure 2] Figure 1 is a schematic cross-sectional side view of the aerosol supply device. [Figure 3] Figure 1 is a schematic perspective view of the cover assembly for the aerosol supply device in a closed position, with several components shown translucently to reveal hidden features. [Figure 4]Figure 3 is a schematic perspective view of the cover mechanism in an open position, with several components shown semi-transparently to reveal hidden features. [Modes for carrying out the invention]

[0039] In this specification, the term “aerosol-generating material” refers to a material capable of generating an aerosol when subjected to energy application, for example, by heating, irradiation, or any other method. Aerosol-generating materials may be in the form of, for example, a solid, liquid, or gel, and may or may not contain active substances and / or flavorings. Aerosol-generating materials may include any plant-based material, such as tobacco-containing materials, and may include one or more of the following: tobacco, tobacco derivatives, puffed tobacco, recycled tobacco, or tobacco substitutes. Aerosol-generating materials may also include other non-tobacco products, which may or may not contain nicotine, depending on the product. Aerosol-generating materials may be in the form of, for example, a solid, liquid, gel, or wax. Aerosol-generating materials may also be, for example, a combination or mixture of materials. Aerosol-generating materials are sometimes referred to as “smoking materials.”

[0040] The aerosol-generating material may include an adhesive and an aerosol-forming agent. Optionally, an activator and / or filler may be present. Optionally, a solvent such as water may also be present, and one or more other components of the aerosol-generating material may or may not be soluble in the solvent. In some embodiments, the aerosol-generating material is substantially free of plant-based materials. In some embodiments, the aerosol-generating material is substantially free of tobacco.

[0041] The aerosol-generating material may include, or be, an amorphous solid. The amorphous solid may be a monolithic solid. In some embodiments, the amorphous solid may be a dry gel. The amorphous solid is a solid material that can hold some fluid, such as a liquid, inside. In some embodiments, the aerosol-generating material may include, for example, about 50% by weight, 60% by weight, or 70% by weight of amorphous solid to about 90% by weight, 95% by weight, or 100% by weight of amorphous solid.

[0042] The aerosol-generating material may include an aerosol-generating film. The aerosol-generating film may include or be a sheet, and may optionally be shredded to form shredded sheets. The aerosol-generating sheet or shredded sheet does not need to contain tobacco substantially.

[0043] According to this disclosure, a “non-combustible” aerosol supply system is a system that does not burn or incinerate the aerosol-generating materials of the aerosol supply system (or its components) in order to facilitate the delivery of at least one substance to the user.

[0044] In some embodiments, the delivery system is a non-combustible aerosol supply system, such as a powered non-combustible aerosol supply system.

[0045] In some embodiments, the non-combustion aerosol delivery system is an e-cigarette, also known as a vaping device or electronic nicotine delivery system (END), but it should be noted that the presence of nicotine in the aerosol-generating material is not a requirement.

[0046] In some embodiments, the non-combustion aerosol supply system is an aerosol-generating material heating system, also known as a non-combustion heating system. An example of such a system is a tobacco heating system.

[0047] In some embodiments, a non-combustible aerosol supply system is a hybrid system for generating aerosols using a combination of aerosol-generating materials, one or more of which can be heated. Each of the aerosol-generating materials can be, for example, in the form of a solid, liquid, or gel, and may or may not contain nicotine. In some embodiments, the hybrid system includes a liquid or gel aerosol-generating material and a solid aerosol-generating material. The solid aerosol-generating material may include, for example, tobacco or a non-tobacco product.

[0048] Typically, a non-combustible aerosol supply system may comprise a non-combustible aerosol supply device and consumables for use with the non-combustible aerosol supply device.

[0049] In some embodiments, the disclosure relates to consumables comprising aerosol-generating materials and configured for use with non-combustible aerosol supply devices. These consumables may be referred to as articles throughout the disclosure.

[0050] In some embodiments, a non-combustible aerosol supply system, such as the non-combustible aerosol supply device, may include a power source and a controller. The power source may be, for example, a power source or a heat-generating power source. In some embodiments, the heat-generating power source may include a carbon substrate, which can be energized to disperse the force in the form of heat to an aerosol-generating material or heat-transferring material adjacent to the heat-generating power source.

[0051] In some embodiments, a non-combustible aerosol supply system may include an area for receiving consumables, an aerosol generator, an aerosol generation area, a housing, a mouthpiece, a filter, and / or an aerosol modifier.

[0052] In some embodiments, consumables for use with a non-combustible aerosol supply device may include aerosol generating material, an aerosol generating material storage area, an aerosol generating material transfer component, an aerosol generator, an aerosol generating area, a housing, a roll of paper, a filter, a mouthpiece, and / or an aerosol corrector.

[0053] An aerosol generating device can receive an article containing aerosol-generating material for heating. In this context, “article” is a component that contains or is contained in aerosol-generating material during use, which is heated during use to volatilize the aerosol-generating material and optionally other components. A user can insert an article into the aerosol generating device, heat the article to generate an aerosol, and then inhale the aerosol. The article may be of a predetermined or specific size, for example, configured to be placed within a heating chamber of a device of a size that receives the article.

[0054] Figure 1 shows an aerosol supply device 100 for generating an aerosol from an aerosol-generating material. Roughly speaking, the device 100 can be used to heat a replaceable article 300 containing an aerosol-generating material to generate an aerosol or other aspirable medium, which is then aspirated by the user of the device 100. The article 300 and the device 100 together form an aerosol supply system 10.

[0055] The device 100 comprises a body 101, which includes a chamber 105, as shown in Figure 2. The chamber 105 defines a heating section 107, which is positioned to receive an article 300 at least partially. A housing 102 surrounds and accommodates various components of the body 101. An opening 103 is formed at one end of the body 101, communicating with the chamber 105. The article 300 can be at least partially inserted into the heating section 107 through the opening 103 for heating by the aerosol generator 150 (see Figure 2). During use, the article 300 can be heated by one or more components of the aerosol generator 150.

[0056] The device 100 also includes a button assembly 200 that, when pressed, activates the device 100. For example, a user can turn on the device 100 by operating the button assembly 200. The button assembly 200 can be assembled as part of other assemblies of the aerosol supply device 100.

[0057] The aerosol generator 150 defines the longitudinal axis X.

[0058] Figure 2 is a schematic cross-sectional view of device 100. Device 100 includes electrical components such as a connector / port 160 that can receive a cable for charging device 100. For example, connector 160 can be a charging port, such as a USB charging port. In some examples, in addition or alternatively, connector 160 can be used to transmit data between device 100 and another device, such as a computing device.

[0059] Device 100 includes a power source 170, which is a battery such as a rechargeable or non-rechargeable battery. Examples of suitable batteries include, for example, lithium batteries (such as lithium-ion batteries), nickel batteries (such as nickel-cadmium batteries), and alkaline batteries. The battery is electrically coupled to the aerosol generator 150 and supplies power to heat the aerosol-generating material under the control of a controller when needed.

[0060] Device 100 comprises an electronic module 112. The electronic module 112 may include, for example, a printed circuit board (PCB). The PCB may support at least one controller, such as a processor, and memory. The PCB may also have one or more electrical tracks for electrically connecting various electronic components of device 100 together. For example, battery terminals may be electrically connected to the PCB, thus distributing power throughout device 100.

[0061] The main body 101 defines the end of the device 100. The end of the device 100 closest to the opening 103 is the closest to the user's mouth during use and can therefore be called the proximal end (or mouthpiece end) 104 of the device 100. During use, the user inserts the article 300 into the opening 103, operates the aerosol generator 150 to begin heating the aerosol generating material, and utilizes the aerosol generated within the device. This causes the aerosol to flow through the device 100 along the flow path toward the proximal end of the device 100.

[0062] The other end of the device furthest from the opening 103 is the end furthest from the user's mouth during use and can therefore be called the distal end 106 of the device 100. When the user utilizes the aerosol generated within the device 100, the aerosol flows toward the proximal end of the device 100. The terms proximal and distal applied to the features of the device 100 are explained by referring to the relative positions of such features toward each other in the proximal-distal direction along the longitudinal axis X.

[0063] In this specification, the term "integrated component" refers to a component of device 100 that cannot be separated into two or more components after the assembly of device 100. Integral formation refers to two or more features formed as an integrated component during the manufacturing stage of the components.

[0064] An airflow passage 180 extends through the main body 101. The airflow passage 180 extends to the air inlet 190. Other airflow configurations are also conceivable. For example, an airflow can be provided between a receptacle defining the chamber 105 and the article 300.

[0065] In one example, the aerosol generator 150 includes an inductive heating system that includes a magnetic field generator. The magnetic field generator includes an inductor coil assembly. The aerosol generator 150 also includes a heating element, which is also known as a susceptor.

[0066] A susceptor is a material that can be heated by the intrusion of a fluctuating magnetic field, such as an alternating magnetic field. The susceptor can be a conductive material, and therefore, the intrusion of a fluctuating magnetic field causes inductive heating of the heating material. The heating material can be a magnetic material, and therefore, the intrusion of a fluctuating magnetic field causes magnetic hysteresis heating of the heating material. A susceptor can be both conductive and magnetic, and therefore, a susceptor can be heated by both heating mechanisms. In this specification, a device configured to generate a fluctuating magnetic field is referred to as a magnetic field generator.

[0067] The aerosol generator 150 is an induction heating assembly comprising various components for heating the aerosol-generating material of article 300 via an induction heating process. Induction heating is a process of heating a conductive object (such as a susceptor) by electromagnetic induction. The induction heating assembly may comprise an induction element, for example, one or more inductor coils, and a device for passing a fluctuating current, such as an alternating current, through the induction element. The fluctuating current in the induction element results in a fluctuating magnetic field. The fluctuating magnetic field penetrates a susceptor suitably positioned relative to the induction element, generating eddy currents within the susceptor. The susceptor has electrical resistance to eddy currents, and therefore the flow of eddy currents against this resistance heats the susceptor by Joule heating. If the susceptor contains a ferromagnetic material such as iron, nickel, or cobalt, heat may also be generated by magnetic hysteresis losses within the susceptor, i.e., fluctuations in the orientation of magnetic poles within the magnetic material resulting from alignment with the fluctuating magnetic field. For example, compared to heating by conduction, induction heating allows for rapid heating because heat is generated within the susceptor. Furthermore, since no physical contact is required between the induction heater and the susceptor, it is possible to increase structural and application flexibility.

[0068] An inductor coil assembly includes an inductor coil. Depending on the embodiment, the number of inductor coils may vary. Depending on the embodiment, two or more inductor coils may be used. The inductor coil assembly also includes a coil support. The coil support is tubular.

[0069] The aerosol generator 150 may also include, or alternatively, other types of heating systems. Depending on the embodiment, the aerosol generator 150 may include a resistance heating system.

[0070] The heating element is part of the heating assembly. In this example, the heating element is hollow and therefore defines at least a portion of the receptacle into which the aerosol-generating material is received. For example, article 300 can be inserted into the heating element. The heating element is tubular and has a circular cross-section. The heating element has a generally constant diameter along its axial length.

[0071] In some embodiments, the heating assembly defines a receptacle, and the heating element stands upright within the receptacle. The heating element may comprise pins or blades positioned to penetrate the consumable. In some embodiments, the consumable comprises the heating element, and the aerosol supply device comprises an inductor coil positioned to inductively heat the heating element within the consumable.

[0072] The heating element is formed from a conductive material suitable for heating by electromagnetic induction. In this example, the susceptor is made from carbon steel. It will be understood that other suitable materials, such as ferromagnetic materials like iron, nickel, or cobalt, can also be used.

[0073] In other embodiments, the feature acting as a heating element is not limited to induction heating. The feature acting as a heating element can also be heated by electrical resistance. Therefore, the aerosol generator 150 may be equipped with electrical contacts for electrical connection to the device in order to electrically activate the heating element by passing an electrical energy flow through it.

[0074] The receptacle and article 300 are sized such that article 300 is received by the heating element. This helps to ensure efficient heating. Article 300 in this example includes an aerosol-generating material. The aerosol-generating material is placed inside the receptacle. Article 300 may also comprise other components, such as at least one of a filter, packaging material, and a cooling structure.

[0075] The air passage 180 extends from the receptacle. The air passage 180 is located at the distal end. The air passage 180 extending from the receptacle is defined by the flow channel member 182. The heating element 220 and the flow channel member 182 form part of the air passage structure 181.

[0076] The flow path member 182 extends between the heating element and the opening 190. The flow path member 182 is tubular. The flow path member 182 defines an inner diameter. The flow path member extends axially along its length.

[0077] The cover assembly 400 is positioned to selectively cover the opening 103, and the cover assembly 400 will be described in more detail below.

[0078] Figure 3 shows a perspective view of the cover assembly 400 with respect to the aerosol supply device in a closed position, and Figure 4 shows a perspective view of the cover assembly 400 in an open position. Some components are shown transparent to allow for clear illustration and explanation of the feature components.

[0079] The cover assembly 400 can be used with the aerosol supply device 100 shown in Figures 1 and 2, and will be described by referring to that device. Depending on the embodiment, the cover assembly 400 may be used with other device components. The cover assembly 400 comprises a cover mechanism 401.

[0080] Broadly speaking, the cover mechanism 401 comprises a body 402 defining the opening 103 of the aerosol supply device, one or more cover members 410, 411 arranged to selectively cover the opening 103, and an actuator 420. In these figures, the actuator 420 is shown transparent to clearly show the features below that are hidden by this component. One or more connecting members 430 are arranged to move the cover members 410, 411 between a relatively open position in which at least a portion of an article can pass through the opening and a relatively closed position in which at least a portion of an article is prevented from passing through the opening. The cover members 410, 411 are pivotably attached to the body 402. The actuator 420 overlaps the cover members 410, 411 and forms the exterior of the cover mechanism 401. The actuator 420 is exposed to the outside of the aerosol supply device 100 and is arranged to be manually operated by the user.

[0081] The cover assembly 400 comprises a body 402, which is part of the body 101 of the aerosol supply device 100. The body 402 is a rigid member. The body 402 defines a portion of the housing 102. A seal (not shown) can be provided between the body 402 and other components of the housing 102 of the aerosol supply device 100. The seal can extend around the entire perimeter of the body 402. In other embodiments, the body 402 can be integrally formed with the housing 102.

[0082] The main body 402 includes an opening 404, which is the opening 103 of the aerosol supply device 100. The opening 404 communicates with the chamber 105. The opening 404 is sized to receive at least a portion of an article containing an aerosol-generating material, such as article 300.

[0083] The cover mechanism 401 of the cover assembly 400 comprises one or more cover members 410, 411 arranged to selectively cover the opening 404. The cover members 410, 411 cooperate to selectively cover the opening 404. In this embodiment, two cover members 410, 411 are provided. In other embodiments, a different number of cover members can be provided, such as one cover member, three cover members, four cover members, or substantially any number of cover members.

[0084] The cover mechanism 401 comprises a first cover member 410 and a second cover member 411. The first cover member 410 and the second cover member 411 abut each other in a relatively closed position. The first cover member 410 defines a first edge 410a, and the second cover member 411 defines a second edge 411a. The first edge 410a and the second edge 411a are arranged to coincide with each other. That is, the first edge 410a and the second edge 411a have profiles such that they contact each other along their entire length in a relatively closed position. The first edge 410a includes an arched portion, and the second edge 411a includes a corresponding arched portion. The first edge 410a is S-shaped, and the second edge 411a is a corresponding S-shape. This provides a particularly space-efficient configuration for the cover members 410 and 411.

[0085] In embodiments comprising three or more cover members 410, 411, each cover member may include multiple edges that abut against adjacent cover members 410, 411.

[0086] The cover members 410 and 411 are interchangeable; that is, the cover members 410 and 411 are identical. In other embodiments, the cover members 410 and 411 may be different from each other.

[0087] This explanation will proceed by referring to a single cover member 410, but it will be understood that the other cover members 411 also have similar or identical features.

[0088] The cover member 410 is in slidable contact with the main body 402. The cover member 410 is substantially planar. The cover member 410 includes a blade portion 412 positioned to at least partially cover the opening 404. In embodiments with only a single cover member, the blade portion 412 is positioned to completely cover the opening 404. In embodiments with two cover members, each cover member is positioned to cover half of the opening 404, as shown in Figure 3, and thus together to completely cover the opening 404. These proportions may differ.

[0089] The cover member 410 includes an arm portion 414. The arm portion 414 extends from the blade portion 412. The arm portion 414 overlaps the body 402 in both a relatively open position and a relatively closed position. Therefore, the arm portion 414 can be described as an overlapping portion. The blade portion 412 and the arm portion 414 are integrally formed. In other embodiments, the blade portion 412 and the arm portion 414 are separate components in a fixed relationship.

[0090] In this specification, the term "fixed relationship" refers to a relationship in which two components cannot move relative to each other.

[0091] The cover member 410 includes a lower swivel pin (not shown) that acts as a swivel member. The lower swivel pin extends from the arm portion 414. The lower swivel pin is spaced apart from the blade portion 412. The lower swivel pin is received by the inner diameter of the main body 402. Thus, the cover member 410 is swivelably attached to the main body 402. In other embodiments, the main body 402 may include a pin, and the cover member 410 may have an inner diameter for receiving the pin.

[0092] In some embodiments, the cover member 410 may have an upper swivel pin acting as a swivel member instead of, or in addition to, the lower swivel pin. In such embodiments, the body 402 may include an upper and a lower section, with the cover member 410 held between the upper and lower sections. One of the upper and lower swivel pins may be omitted. The upper swivel pin extends from the arm section 414. The upper swivel pin is spaced apart from the blade section 412. The upper swivel pin extends from the arm section 414 on the side opposite to the lower swivel pin. The upper and lower swivel pins share a common axis. The upper and lower swivel pins extend parallel to the longitudinal axis.

[0093] The cover member 410 is a single, integrated component. The cover member 410 is formed as a single unit. In other embodiments, the cover member 410 can be a composite component formed from multiple parts. For example, the upper and lower swivel pins can be a single pin extending through the arm portion 414.

[0094] The cover mechanism 401 includes an operating member 420. The operating member 420 is rotatably mounted on the main body 402. The operating member 420 is operable to selectively operate the cover members 410 and 411. The operating member 420 is exposed to the outside of the aerosol supply device 100. The operating member 420 is positioned to be manually operated by the user to operate the cover members 410 and 411.

[0095] The actuating member 420 is substantially annular in shape. The actuating member 420 defines an opening 422. The opening 422 is centrally located within the actuating member 420. The opening 422 can also be omitted. The opening 422 overlaps with the opening 404 of the main body 402. The opening 422 is axially aligned with the opening 404 of the main body 402. Therefore, the opening 422 communicates with the heating section 107.

[0096] The actuating member 420 is positioned to rotate on the main body 402 to actuate the cover members 410 and 411. The actuating member 420 covers a portion of the main body 402; that is, a portion of the main body 402 extends into the actuating member 420. The axis of rotation of the actuating member 420 is parallel to the longitudinal axis of the chamber 105. In some embodiments, the axis of rotation is lateral or perpendicular.

[0097] The main body 402 includes an actuation member mount 424. The actuation member 420 is rotatably engaged with the actuation member mount 424. The actuation member mount 424 substantially restricts the movement of the actuation member 420 relative to the main body to rotational motion. The actuation member 420 includes an arrangement feature 425 that engages with the actuation member mount 424. The arrangement feature is a circumferential projection or other preferred feature on the inner surface of the actuation member 420.

[0098] The actuation member mount 424 includes a clip 426 that acts as a retaining structure. The clip 426 is elastic. The actuation member mount 424 may have multiple clips 426.

[0099] The cover members 410 and 411 are positioned between the main body 402 and the operating member 420. The cover members 410 and 411 make sliding contact with the main body 402. The cover members 410 and 411 also make sliding contact with the operating member 420. Such a configuration helps to limit the intrusion of debris.

[0100] The rotation of the actuator 420 relative to the main body 402 causes the cover members 410 and 411 to move between a relatively open position and a relatively closed position. The connecting member 430 connects the cover members 410 and 411 to the actuator 420 to enable this movement, as will be described in detail below. The cover assembly 400 is configured to operate selectively between a relatively open position and a relatively closed position. Such positions are related to each other. In the relatively open position, at least a portion of the article 300 is allowed to pass through the opening 404. In the relatively closed position, at least a portion of the article 300 is prevented from passing through the opening 404.

[0101] The term "relatively open position" will be understood to mean any position in which at least a portion of the article 300 can pass through the opening, i.e., a fully open position and an intermediate position that leaves sufficient space for the portion of the article 300 to be inserted. The term "relatively closed position" will be understood to mean any position in which the portion of the article 300 is prevented from passing through the opening 404, i.e., a fully closed position and an intermediate position in which there is not enough space for the article 300 to pass through the opening.

[0102] In this embodiment, when in a relatively open position, the cover members 410 and 411 do not overlap the opening.

[0103] In this embodiment, the rotation of the actuarial member 420 relative to the main body 402 causes the cover members 410, 411 to move to or from the fully closed position. The term fully closed position will be understood to mean that the cover members 410, 411 completely close the opening 404. In this specification, the terms open and closed as applied to the features of the cover mechanism 401 will be explained in relation to one another.

[0104] The cover members 410 and 411 are positioned to pivot relative to the main body 402. The cover members 410 and 411 are positioned to pivot in a direction perpendicular to the rotation axis of the actuator 420. The rotation axis of the actuator 420 is parallel to the longitudinal axis of the chamber. Therefore, the movement of the cover members 410 and 411 between a relatively open position and a relatively closed position is a rotation of the cover members 410 and 411. In other embodiments, such movement may also include, or otherwise, translation, i.e., linear motion.

[0105] The cover mechanism 401 comprises a plurality of connecting members 430. The connecting members 430 connect the cover members 410, 411 to the operating member 420. The connecting members 430 provide a mechanical connection between the cover members 410, 411 and the operating member 420. In this embodiment, the cover mechanism 401 comprises one connecting member 430 for each cover member 410, 411. That is, the cover mechanism 401 comprises two connecting members 430. In other embodiments, the ratio of connecting members 430 to cover members 410, 411 may differ. For example, two connecting members may be provided for each cover member 410, 411.

[0106] The connecting members 430 are identical. In other embodiments, the connecting members 430 may be different from one another. This description will proceed by referring to a single connecting member 430, but it will be understood that other connecting members 430 also have similar or identical features.

[0107] The connecting member 430 is pivotably attached to the operating member 420. The connecting member 430 pivots around a fixed point on the operating member 420. In some embodiments, the connecting member 430 includes a pin 432 that is received in the inner diameter of the operating member 420. In other embodiments, the operating member 420 includes a pin that is received in the inner diameter of the connecting member 430. In other embodiments, both the connecting member 430 and the operating member 420 have inner diameters, and separate pins are provided to be received in both inner diameters.

[0108] The connecting member 430 is rotatably attached to the cover member 410. The connecting member 430 is rotatably attached to the lower surface of the cover member 410.

[0109] The connecting member 430 pivots around a fixed point on the cover member 410. In some embodiments, the connecting member 430 includes a pin (not shown) that is received in the inner diameter of the cover member 410. In other embodiments, the cover member 410 includes a pin that is received in the inner diameter of the connecting member 430. In other embodiments, both the connecting member 430 and the cover member 410 have inner diameters, and separate pins are provided to be received in both inner diameters.

[0110] The connecting member 430 does not move linearly parallel to the cover member 410. The connecting member 430 does not move linearly parallel to the actuating member 420. In other words, the connecting member 430 is limited to rotation only relative to the actuating member 420 and the cover member 410, respectively.

[0111] The connecting member 430 is an elongated member. The connecting member 430 defines a first end and a second end. The connecting member 430 is pivotably attached to the operating member 420 near the first end. The connecting member 430 is pivotably attached to the cover member 410 near the second end.

[0112] The connecting member 430 is a rod. The connecting member 430 is made from a plastic material. The connecting member 430 is made from polyetheretherketone (PEEK). The connecting member 430 is an integral component. The connecting member 430 is integrally formed.

[0113] The connecting member 430 is a rigid member. This allows the connecting member 430 to push and pull the cover member 410. This allows the connecting member 430 to selectively induce movement of the cover member 410 in both the first and second directions.

[0114] The connecting member 430 is pivotably attached to the blade portion 412 of the cover member 410. The cover member 410 defines a first end and a second end. The connecting member 430 is pivotably attached to the cover member 410 near the first end, and the cover member 410 is pivotably attached to the main body 402 near the second end.

[0115] The connecting member 430 is pivotably attached to the cover member 410 at a point proximal to the point where the cover member 410 is attached to the main body 402. This provides a relationship in which the movement of the connecting member 430 results in a greater movement of the blade portion of the cover member 410. This reduces the required range of motion of the operating member and provides a space-efficient structure.

[0116] The rotation of the operating member 420 relative to the main body 402 causes the cover members 410 and 411 to move via the connecting member 430. When the operating member 420 is rotated by the user, the connecting member 430 moves the cover members 410 and 411 between a relatively open position and a relatively closed position.

[0117] Figure 3 shows the cover mechanism 401 in the closed position, and Figure 4 shows the cover mechanism 401 in the open position. The cover members 410 and 411 are movable between the closed position shown in Figure 3 and the open position shown in Figure 4. As shown in these figures, rotating the actuator 420 clockwise moves the cover members 410 and 411 toward the closed position. As shown in these figures, rotating the actuator 420 counterclockwise moves the cover members 410 and 411 toward the open position. In other embodiments, these directions can be reversed. In some embodiments, the cover mechanism 401 contains a lubricant.

[0118] The cover mechanism 401 includes a magnetic biasing component 440. The magnetic biasing component 440 is configured to bias the cover members 410, 411 toward at least one of a relatively open position and a relatively closed position. It will be understood that the magnetic biasing component can be used in a cover mechanism having a single cover member or any number of cover members, such as three or more cover members. Although rotational biasing has been described above, it will be understood that the magnetic biasing component 440 can also be used in conjunction with other cover mechanism components, such as translational motion. Linear and nonlinear biasing motion can be provided.

[0119] The magnetic biasing assembly 440 includes a first magnetic component 442. The first magnetic component 442 is fixedly connected to the actuator 420. In this embodiment, the first magnetic component 442 is bonded to the actuator 420. The first magnetic component 442 is at least partially embedded in the actuator 420.

[0120] The magnetic biasing assembly 440 includes a second magnetic assembly 444. The second magnetic assembly 444 is fixedly connected to the main body 402. In this embodiment, the second magnetic assembly is bonded to the main body 402. The second magnetic assembly 444 is at least partially embedded in the main body 402.

[0121] The rotation of the actuator 420 causes relative motion between the first magnetic configuration 442 and the second magnetic configuration 444. The first magnetic configuration 442 and the second magnetic configuration 444 are arranged to interact and bias the rotation of the actuator 420 relative to the body 402. The first magnetic configuration 442 and the second magnetic configuration 444 are arranged to attract each other in a relatively open position and a relatively closed position. The magnitude and direction of the magnetic force generated between the first magnetic configuration 442 and the second magnetic configuration 444 depend on their positions relative to each other.

[0122] The first magnetic configuration 442 and the second magnetic configuration 444 are arranged to repel each other at an intermediate position between a relatively open position and a relatively closed position. The magnetic biasing configuration 440 is configured to bias the cover members 410, 411 away from the intermediate position. The intermediate position is midway between the relatively open position and the relatively closed position. Depending on the embodiment, the location of the intermediate position may vary; for example, the intermediate position may be one-third of the path between the relatively open position and the relatively closed position.

[0123] The magnetic biasing assembly 440 is configured to bias the cover members 410 and 411 toward the relatively open position over a first range of motion adjacent to the relatively open position, and the magnetic biasing assembly 440 is configured to bias the cover members 410 and 411 toward the relatively closed position over a second range of motion adjacent to the relatively closed position.

[0124] The intermediate position provides a division between the first range of motion and the second range of motion. When the actuator 420 rotates and moves the cover members 410, 411 from the relatively open position, the cover members 410, 411 are pushed back towards the relatively open position and away from the intermediate position. If the user applies enough force to overcome this pushback and the cover members 410, 411 pass the intermediate position, the cover members 410, 411 are pushed back towards the relatively closed position and away from the intermediate position. The same applies in the reverse direction.

[0125] The cover mechanism 401 returns to its relatively open or relatively closed position unless an external force strong enough to overcome the magnetic force provided by the magnetic biasing component 440 is present. This provides an improved user experience because the user does not need to rotate the actuator 420 across its entire range of motion to put the cover members 410, 411 into the relatively closed or open position. Consequently, the cover members 410, 411 are less likely to remain in intermediate positions (including substantially any position between the intermediate position or the relatively open and relatively closed positions described above), which could cause obstruction or inconvenience.

[0126] The first magnetic configuration 442 includes a first magnetic element 446. In this embodiment, the first magnetic configuration 442 consists of a single magnetic element 446, but in some embodiments, the first magnetic configuration 442 may include further magnetic elements.

[0127] The second magnetic configuration 444 includes a second magnetic element 448. The first magnetic element 446 is oriented so that it has a magnetic polarity opposite to that of the second magnetic element 448, so that the first magnetic element 446 and the second magnetic element 448 attract each other. When the cover members 410, 411 are in a relatively open position, the first magnetic element 446 is positioned proximal to the second magnetic element 448. When the cover members 410, 411 are in a relatively open position, the first magnetic element 446 is positioned directly above the second magnetic element 448 parallel to the axial direction X, although this may differ depending on the embodiment.

[0128] The second magnetic element 448 is positioned at or near the end of the range of motion of the first magnetic element 446. This allows the second magnetic element 448 to fully pull the first magnetic element 446 to the end of its range of motion. This reduces instability or rattle of the cover mechanism 401.

[0129] The second magnetic configuration 444 includes a third magnetic element 450. The third magnetic element is oriented to have a magnetic polarity opposite to that of the first magnetic element 446, such that the first magnetic element 446 and the third magnetic element 450 attract each other. When the cover members 410, 411 are in a relatively closed position, the first magnetic element 446 is positioned proximal to the third magnetic element 450. When the cover members 410, 411 are in a relatively open position, the first magnetic element 446 is positioned directly above the third magnetic element 450 parallel to the axial direction X, although this may differ depending on the embodiment.

[0130] The third magnetic element 450 is positioned at or near the end of the range of motion of the first magnetic element 446. This allows the third magnetic element 450 to fully pull the first magnetic element 446 to the end of its range of motion. This reduces instability or rattle of the cover mechanism 401.

[0131] The second magnetic configuration 444 includes an intermediate magnetic element 452. Therefore, in this embodiment, the second magnetic configuration consists of three magnetic elements. Depending on the embodiment, the second magnetic configuration may consist of more or fewer magnetic elements. For example, the intermediate magnetic element may be omitted, or further intermediate or other magnetic elements may be provided.

[0132] In some embodiments, the second magnetic element 448 and the third magnetic element 450 can be omitted. In some embodiments, the second magnetic configuration 444 can consist only of an intermediate magnetic element. That is, instead of utilizing the attractive force between magnetic configurations 442 and 444, the magnetic biasing configuration 440 can push rather than pull the first magnetic configuration 442 by relying solely on the repulsive force between magnetic configurations 442 and 444. Such embodiments can enable simpler manufacturing, lighter weight, and lower component costs.

[0133] In embodiments where the intermediate magnetic element 452 is omitted, the cover mechanism 401 is not biased, or is only weakly biased over a portion of its range of motion. In some embodiments, the cover mechanism 401 can be biased over its entire range of motion. This reduces the change in which the cover mechanism 401 becomes immobile, thereby increasing user convenience. In embodiments where the intermediate magnetic element 452 is omitted, the first magnetic element 446 does not move beyond the repelling intermediate magnetic element 452, which further provides lower mechanical stress within the cover mechanism 401. This improves the reliability and lifespan of the cover mechanism 401.

[0134] The first magnetic element 446 is oriented so that it has the same magnetic polarity as the intermediate magnetic element 452, such that the first magnetic element 446 and the intermediate magnetic element 452 repel each other. When the cover members 410 and 411 are in the intermediate position, the first magnetic element 446 is positioned proximal to the intermediate magnetic element 452. When the cover members 410 and 411 are in a relatively open position, the first magnetic element 446 is positioned directly above the intermediate magnetic element 452 parallel to the axial direction X, although this may differ depending on the embodiment.

[0135] The intermediate magnetic element 452 is positioned between the second magnetic element 448 and the third magnetic element 450. The second magnetic element 448, the intermediate magnetic element 452, and the third magnetic element 450 are arranged in series. The second magnetic element 448, the intermediate magnetic element 452, and the third magnetic element 450 are arranged in a circular path. The first magnetic element 446 is positioned to move along the circular path in response to the rotation of the operating member.

[0136] In summary, the second magnetic configuration 444 includes a plurality of magnetic elements 446, 448, 450 arranged along the propagation path of the first magnetic configuration 442. The first magnetic configuration 442 is smaller than the second magnetic configuration 444 and overlaps with a portion of the second magnetic configuration 444 over its entire range of motion. Depending on the embodiment, the range of motion of the first magnetic configuration may not overlap with the second magnetic configuration in whole or in part.

[0137] This configuration makes it possible to apply a biasing force between the first magnetic configuration 442 and the second magnetic configuration 444 throughout the entire range of motion of the cover mechanism 401. This allows for efficient operation of the magnetic force, as its direction is parallel or tangential to the path of the first magnetic configuration 442 throughout the entire range of motion. This reduces the mechanical stress on the cover mechanism 401 and provides improved stability and control over the movement of the cover mechanism 401. Furthermore, this configuration makes it possible to make the strength of the biasing force more consistent throughout the range of motion of the cover mechanism 401 compared to embodiments that provide fewer magnetic elements, by limiting the maximum distance between the first magnetic element 446 and any other magnetic element at any position along the range of motion.

[0138] The second magnetic configuration 444 and the first magnetic configuration 442 are spaced apart from each other in the axial direction X of the aerosol supply device 100. A gap is provided between the first magnetic configuration 442 and the second magnetic configuration 444. The gap is less than 3 mm, less than 2 mm, less than 1 mm, or less than 0.5 mm. The gap is greater than 0.01 mm. The gap is selected to minimize the intrusion of debris between the magnetic configurations 442 and 444 and to minimize the risk of clogging or wear between them. Depending on the embodiment, further components may be provided between the first magnetic configuration 442 and the second magnetic configuration 444.

[0139] When the cover members 410 and 411 are in a relatively open position, a relatively closed position, and an intermediate position between the relatively open position and the relatively closed position, the first magnetic configuration 442 is positioned to overlap at least a portion of the second magnetic configuration 444 in the radial plane of the aerosol supply device 100.

[0140] When the cover members 410 and 411 are in a relatively open position, the first magnetic configuration 442 is positioned to overlap the first portion of the second magnetic configuration 444 in the radial plane of the aerosol supply device 100. The first portion of the second magnetic configuration 444 includes the first magnetic element 446.

[0141] When the cover members 410 and 411 are in the intermediate position, the first magnetic configuration 442 is positioned to overlap the second portion of the second magnetic configuration 444 in the radial plane of the aerosol supply device 100. The second portion of the second magnetic configuration 444 includes an intermediate magnetic element 452.

[0142] When the cover members 410 and 411 are in a relatively closed position, the first magnetic configuration 442 is positioned to overlap the third portion of the second magnetic configuration 444 in the radial plane of the aerosol supply device 100. The third portion of the second magnetic configuration includes a third magnetic element 450.

[0143] The magnetic biasing assembly 440 includes a third magnetic component 454. The third magnetic component 454 is fixedly connected to the actuator 420. In this embodiment, the third magnetic component 454 is bonded to the actuator 420. The third magnetic component 454 is at least partially embedded in the actuator 420.

[0144] The magnetic biasing assembly 440 includes a fourth magnetic component 456. The fourth magnetic component 456 is fixedly connected to the main body 402. In this embodiment, the fourth magnetic component 456 is bonded to the main body 402. The fourth magnetic component 456 is at least partially embedded in the main body 402.

[0145] The third magnetic configuration 454 and the fourth magnetic configuration 456 each contain features similar to or identical to those of the first magnetic configuration 442 and the second magnetic configuration 444, respectively. The same reference numbers used for the features of the third magnetic configuration 454 and the fourth magnetic configuration 456 are used for the features of the first magnetic configuration 442 and the second magnetic configuration 444. The third magnetic configuration 454 and the fourth magnetic configuration 456 are arranged to interact with each other to bias the rotation of the actuarial member 420 relative to the body 402.

[0146] The third magnetic configuration 454 and the fourth magnetic configuration 456 are positioned on the opposite side of the opening 404 from the first magnetic configuration 442 and the second magnetic configuration 444, respectively. This provides a symmetrical design that minimizes internal stress in the cover mechanism 401 and improves the stability and control of the cover mechanism 401.

[0147] Depending on the embodiment, further magnetic configurations can be provided to further improve the stability of the motion of the cover mechanism 401. In such embodiments, further magnetic configurations can be provided as pairs of magnetic configurations similar to or identical to the first magnetic configuration 442 and the second magnetic configuration 444.

[0148] Embodiments consisting only of the first magnetic configuration 442 and the second magnetic configuration 444, i.e., omitting the third magnetic configuration 454 and the fourth magnetic configuration 456 or other magnetic configurations, can provide lower complexity, more convenient manufacturing, and lower component costs.

[0149] In embodiments consisting only of the first magnetic configuration 442, the second magnetic configuration 444, the third magnetic configuration 454, and the fourth magnetic configuration 456, i.e., omitting further magnetic configurations, lower mechanical stress can be provided within the cover mechanism 401. This configuration provides a favorable balance between symmetry in the axial direction X of the aerosol supply device 100 and minimization of magnetic force. Minimizing magnetic force can lead to mechanical stress within the cover mechanism 401, increasing wear and potentially reducing the lifespan and reliability of the cover mechanism 401.

[0150] Depending on the embodiment, the first magnetic configuration 442 and the second magnetic configuration 444 can be reversed. That is, the first magnetic configuration 442 can be fixed to the main body 402, and the second magnetic configuration 444 can be fixed to the operating member 420.

[0151] The main body 402 includes a raised portion 458. The raised portion 458 is raised relative to a recess 460 of the main body 402. The raised portion 458 accommodates a second magnetic component 444. The second magnetic component 444 is embedded in the raised portion 458. The recess 460 accommodates cover members 410, 411 and connecting member 430. In embodiments including a third magnetic component 454 and a fourth magnetic component 456, the raised portion 458 can be a first raised portion, and the main body 402 can include a second raised portion 462. The second raised portion 462 can be similar to or identical to the first raised portion 458. The second raised portion 462 accommodates a fourth magnetic component 456. The second raised portion 462 can be joined to the first raised portion 458 or separated from the first raised portion 458. In other words, the first raised portion 458 and the second raised portion 462 can be part of a single continuous raised portion. The recess 460 is defined between the first raised portion 458 and the second raised portion 462.

[0152] The opening 404 is provided in the recess 460. Such a structure can help to trap debris in the area of ​​the opening 404, thereby reducing the intrusion of debris into the cover mechanism 401.
