Description

Technical Field

[0001] This application relates to the field of aerosol generation technology, and more specifically to an aerosol generation apparatus. Background Technology

[0002] Aerosol generating devices utilize the thermal effect of a heating element to heat aerosol generating products placed within their containment cavity, thereby generating aerosols without combustion. Currently, due to the availability of numerous aerosol generating products on the market, each with different sizes and structures, aerosol generating devices require corresponding structures and dimensions for different product models. This means they cannot heat and atomize aerosol generating products of other sizes and shapes, forcing users to purchase only the corresponding aerosol generating products. Furthermore, with the wide variety of aerosol generating products available, users need to purchase specific aerosol generating devices to experience different products, undoubtedly increasing operating costs and leading to a poor user experience. Utility Model Content

[0003] This application provides an aerosol generating device that is compatible with aerosol generating products of various sizes, has a wide range of applications, and reduces user costs.

[0004] This application provides an aerosol generating device, including a heating body, a movable base, a driving assembly, a movable switch, a control board, and a display. The heating body has a receiving cavity for receiving an aerosol generating product and heating the aerosol generating product to generate aerosol. The movable base is movably disposed on one side of the heating body for abutting against the end of the aerosol generating product and forming at least a portion of the cavity wall. The driving assembly is connected to the movable base and drives the movable base to move along the axial direction of the receiving cavity to change the axial length of the receiving cavity. The movable switch is disposed on one side of the driving assembly and can synchronously drive the movable switch to switch between a first state and a second state when the driving assembly drives the movable base to move. The control board is electrically connected to both the movable switch and the heating body and triggers the heating body to operate according to a preset heating curve corresponding to the state of the movable switch. The display is electrically connected to the control board and displays the state of the movable switch and / or the preset heating curve corresponding to the state of the movable switch.

[0005] In some alternative embodiments, the drive assembly includes a rotating disk and a connecting rod having a first end and a second end disposed opposite to each other along its axis, the first end being threaded externally and movably connected to the movable base, and the second end being connected to the rotating disk.

[0006] In some alternative embodiments, the edge of the rotating disk is recessed radially inward to form a groove and a protrusion, the opening of the groove facing the movable switch, the movable switch being in the first state when the rotating disk rotates to the point where the groove corresponds to the movable switch; and when the rotating disk rotates to the point where the protrusion corresponds to the movable switch, the protrusion presses against the movable switch, and the movable switch is in the second state.

[0007] In some optional embodiments, the active switch includes a switch body and a movable part. The switch body is connected to the control plate, and the movable part is movably connected to the switch body. When the rotating disk rotates to the point where the groove corresponds to the active switch, the movable part is released and disposed in the groove. When the rotating disk rotates to the point where the protrusion corresponds to the active switch, the protrusion abuts against the movable part and squeezes the movable part.

[0008] In some alternative embodiments, the switch body has a movable cavity, the movable part is movably disposed within the movable cavity, and at least a portion of the structure is capable of extending out of the movable cavity.

[0009] In some alternative embodiments, the intersection line of the groove and the protrusion is parabolic or semi-circular.

[0010] In some optional embodiments, the aerosol generating device further includes a housing assembly, in which the heating body, the movable base, the driving assembly, the movable switch, and the control board are all disposed within the housing assembly, and the heating body, the movable base, and the driving assembly are arranged sequentially along the axis of the receiving cavity; the display element is disposed within the housing assembly or exposed outside the housing assembly.

[0011] In some optional embodiments, the housing assembly includes a housing body, an inner cover, and an outer cover. The housing body has at least one receiving opening. The inner cover and the outer cover are disposed from the inside to the outside at the receiving opening. The driving assembly is clamped between the inner cover and the outer cover. The inner cover and the outer cover are provided with a through hole along the axial direction of the receiving cavity. One end of the driving assembly passes through the through hole and is flush with the end face of the outer cover.

[0012] In some alternative embodiments, the outer periphery of the drive assembly is provided with a stepped structure, and the inner cover and the outer cover respectively abut against two stepped surfaces of the stepped structure.

[0013] In some alternative embodiments, the aerosol generating device further includes a movable support, which is disposed outside the movable base and the drive assembly, and the movable support has a movable groove along the axial direction of the receiving cavity, and the movable base has a movable block, which is slidably connected to the movable groove.

[0014] The aerosol generating device according to the above embodiments includes a heating body, a movable base, a driving component, a movable switch, a control board, and a display. Because the movable base can move along the axis of the receiving cavity, thereby changing the extension length of the receiving cavity, the generating device can accommodate different aerosol generating products, reducing user operating costs. Due to the cooperation of the movable switch and the control board, the movable switch can switch between a first state and a second state under the drive of the driving component. The control board can trigger different preset heating curves according to the state of the movable switch. These preset heating curves correspond to different aerosol generating products, allowing the aerosol generating products to be heated with a preset heating curve adapted to their characteristics. This ensures that each aerosol generating product achieves optimal suction effect, improving the user experience. Attached Figure Description

Detailed Implementation

[0023] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0024] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0025] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0026] This application provides an aerosol generating apparatus (hereinafter referred to as the generating apparatus), which can be used to heat an aerosol generating article A to generate a usable aerosol.

[0027] It should be noted that the term "aerosol" in this context refers to a dispersion of solid or liquid particles in a gas. The term "aerosol" as used herein can generally refer to substances that have been vaporized, atomized, sprayed, or jetted, or otherwise transformed from a solid or liquid form into an inhalable form containing suspended solid or liquid drug particles.

[0028] As used herein, the term "aerosol-generating article A" refers to any suitable compound or mixture of compounds that facilitates the formation of aerosols (e.g., stable aerosols that are substantially resistant to thermal degradation at the system's operating temperature) during use. Suitable aerosol-generating articles A are well known in the art and include, but are not limited to: polyols such as triethylene glycol, 1,3-butanediol, and glycerol; esters of polyols such as mono-, di-, or triacetic acid esters of glycerol; and aliphatic esters of mono-, di-, or polycarboxylic acids such as dimethyl dodecanoate and dimethyl tetradecanoate. Aerosol-generating article A may include nicotine. Aerosol-generating article A may include water. Aerosol-generating article A may include glycerol (also known as glycerol) having a higher boiling point than nicotine. Aerosol-generating article A may include propylene glycol. Aerosol-generating article A may include plant-based materials. Aerosol-generating article A may include homogeneous plant substrates. Homogeneous plant substrates may contain volatile compounds. These compounds may be released from aerosol-generating article A upon heating.

[0029] With technological advancements, the variety of aerosol generator A models has increased. Currently, two widely used models are TEREA and NSCS. TEREA, a product of Philip Morris International's IQOS brand, offers multiple flavors and is the dedicated aerosol generator A brand for the ILUMA generator. NSCS cartridges (Nature Smoke Cigarettes, Nscs) utilize a unique anaerobic heating technology, allowing the heating zone of the aerosol generator A to naturally generate aerosols in a low-oxygen environment. These aerosols diffuse into the aerobic area and are then extracted through airflow. Both models of aerosol generator A are cylindrical or near-cylindrical in shape, with varying lengths. When inserted into a generator, the device must have a cavity matching the length to ensure complete aerosol release and prevent the generation of impurities that could affect the aerosol flavor. Therefore, each type of aerosol generating product A requires a corresponding generating device. Since these two models have different functional characteristics, users need to purchase two different generating devices to meet their varying experience needs. This undoubtedly increases user costs and is inconvenient for users to carry around, especially as the variety of aerosol generating products A increases. To solve this technical problem, this application provides the following specific solution.

[0030] Please see Figures 1 to 7 The generating device includes a heating body 100, a movable base 200, a drive assembly 300, a movable switch 400, a control panel 500, and a display 600. The heating body 100 has a receiving cavity 110 for receiving the aerosol generating product A and heating the aerosol generating product A to generate aerosol. The movable base 200 is movably disposed on one side of the heating body 100, for abutting against the end of the aerosol generating product A, and forms part of the cavity wall of the receiving cavity 110. The drive assembly 300 is connected to the movable base 200 and is used to drive the movable base 200 along the axis B of the receiving cavity 110. The directional movement changes the axial length of the receiving cavity 110; the movable switch 400 is disposed on one side of the drive assembly 300, and when the drive assembly 300 drives the movable base 200 to move, it can synchronously drive the movable switch 400 to switch between the first state and the second state; the control board 500 is electrically connected to both the movable switch 400 and the heating body 100, and is used to trigger the heating body 100 to operate according to a preset heating curve corresponding to the state of the movable switch 400; the display 600 is electrically connected to the control board 500, and is used to display the state of the movable switch 400 and / or the preset heating curve corresponding to the state of the movable switch 400.

[0031] The heating body 100 includes a heating element, which is constructed to form at least a partial receiving cavity 110. The heat radiation range of the heating element at least covers the matrix segment of the aerosol-generating product A, so that the heating element generates heat after being energized, and heats and atomizes the matrix segment to generate aerosol by means of direct heat conduction heating or hot air flow heating. Specifically, the heating element can be a heating cylinder made of conductive material, a cylindrical structure with heating wire, heating film or heating mesh, or an electromagnetic heating structure, etc., which can generate heat after being energized. No further restrictions are imposed here.

[0032] The active switch 400 and the control board 500 work together to trigger different preset heating curves. Different positions of the active switch 400 can cause the control circuit on the control board 500 to output different circuit signals, thereby causing different currents or voltages on the heating body 100, so that the heating body 100 can work according to different heating curves.

[0033] The coordination of the active switch 400, control panel 500, and display 600 allows the user to monitor the status of the generating device in real time, i.e., which type of aerosol product A the current generating device can be used for. Specifically, when the active switch 400 is switched to the first state, the control panel 500 can send a signal of "0", the display 600 displays the symbol "EE", and the movable base 200 also moves to the first position, with the extension length of the receiving cavity 110 being S1. Figure 2As shown, the device can accommodate the first aerosol-generating product A. The heating body 100 heats the first aerosol-generating product A according to a first preset heating curve. When the active switch 400 switches to the second state, the control board 500 can send a signal of "1", the display 600 displays the "CC" symbol, and the movable base 200 also moves to the second position. The extension length of the accommodating cavity 110 is S2, as shown. Figure 3 As shown, the heating body 100 is capable of accommodating the second aerosol-generating article A, and heats the second aerosol-generating article A according to a second preset heating curve. Of course, the signal symbols and display symbols of the display element 600 are for ease of understanding only; other mutually distinguishable symbols are also within the scope of protection of this application.

[0034] Since the heating body 100 forms a receiving cavity 110, the movable base 200 can move along the axis B of the receiving cavity 110, thereby changing the extension length of the receiving cavity 110, so that the generating device can accommodate aerosol generating products A of different lengths (i.e., specifications). Due to the cooperation of the movable switch 400 and the control board 500, the movable switch 400 can switch between a first state and a second state under the drive of the drive component 300. The control board 500 can trigger different preset heating curves according to the state of the movable switch 400, and these preset heating curves correspond to different aerosol generating products A, so that the aerosol generating product A can be heated with a preset heating curve adapted to its characteristics. This application, through the cooperation of the movable base 200, drive assembly 300, movable switch 400 and control board 500, can easily realize the switching of different preset heating curves and the containment of corresponding aerosol generating products A. This allows the same generating device to be compatible with at least two aerosol generating products A, and enables each aerosol generating product A to achieve the best suction effect. It also reduces the user's operating costs and improves the user experience.

[0035] Please see Figure 4 In some embodiments, the drive assembly 300 includes a rotating disk 310 and a connecting rod 320. The connecting rod 320 has a first end 321 and a second end 322 arranged opposite to each other along its axis. The first end 321 is threaded on the outside and is movably connected to the movable base 200. The second end 322 is connected to the rotating disk 310. Since the first end 321 of the connecting rod 320 is threaded on the outside and the movable base 200 is movably connected to the first end 321, the movable base 200 is driven to move along the axis B of the receiving cavity 110 by means of the rotation of the drive assembly 300, and linear reciprocating motion can be realized. This allows the receiving cavity 110 to be switched to different lengths repeatedly. Moreover, the mechanical principle of this structure is mature and helps to simplify the structure and processing of the production device.

[0036] Please continue reading. Figure 4 and Figure 5 In some embodiments, the edge of the rotating disk 310 is recessed radially inward to form a groove 311 and a protrusion 312. The opening of the groove 311 faces the movable switch 400. When the rotating disk 310 rotates to the point where the groove 311 corresponds to the movable switch 400, the movable switch 400 is in a first state, such as... Figure 5 As shown in the upper middle figure; when the rotating disk 310 rotates to the point where the protrusion 312 corresponds to the movable switch 400, the protrusion 312 presses against the movable switch 400, and the movable switch 400 is in the second state, as shown. Figure 5 As shown in the lower middle of the image.

[0037] Please continue reading. Figure 5 In some embodiments, the active switch 400 includes a switch body 410 and an active part 420. The switch body 410 is connected to the control board 500, and the active part 420 is movably connected to the switch body 410. When the rotating disk 310 rotates to the position where the groove 311 corresponds to the active switch 400, the active part 420 is released and disposed in the groove 311. When the rotating disk 310 rotates to the position where the protrusion 312 corresponds to the active switch 400, the protrusion 312 abuts against the active part 420 and squeezes the active part 420.

[0038] To further ensure the effective release of the active switch 400, an elastic body, such as a spring, is provided between the active part 420 and the switch body 410. When the active part 420 is rotated to correspond with the protrusion 312, the protrusion 312 applies a compressive force to the active part 420, and the elastic body is compressed. When the active part 420 is rotated to correspond with the recess 311, the compressive force applied to the active part 420 disappears, and under the elastic restoring force of the elastic body, the active part 420 is released and positioned in the recess 311.

[0039] In order to protect the movable part 420 and to provide the movable part 420 with sufficient space for movement, the switch body 410 has a movable cavity, the movable part 420 is movably disposed in the movable cavity, and at least part of the structure can extend out of the movable cavity.

[0040] In some embodiments, the intersection line of the groove 311 and the protrusion 312 is parabolic or semi-circular, which provides a buffer space for the state switching of the movable part 420, making the switching of the movable switch 400 smoother.

[0041] In some embodiments, the aerosol generating device further includes a housing assembly 700. The heating body 100, movable base 200, drive assembly 300, movable switch 400, and control board 500 are all disposed within the housing assembly 700, and the heating body 100, movable base 200, and drive assembly 300 are arranged along axis B of the receiving cavity 110. The housing assembly 700 provides installation space for the various components of the generating device and allows them to be integrated into a single structure, facilitating the carrying and transportation of the generating device. The display element 600 is disposed within or exposed within the housing assembly 700. When the display element 600 is disposed within the housing assembly 700, the housing assembly 700 at the position corresponding to the display element 600 is made of transparent material to facilitate user viewing of information on the display element 600. Alternatively, the housing assembly 700 at the position corresponding to the display element 600 can be detachably connected to other parts of the housing assembly 700, allowing the display element 600 to be exposed by rotation or direct separation when viewing is required. The display 600 may be equipped with touch buttons to facilitate user operation and control of the generating device's working status.

[0042] To reduce the difficulty of changing the extension length of the receiving cavity 110, the heating body 100, the movable base 200, and the drive assembly 300 are arranged coaxially.

[0043] Please see Figure 6 In some embodiments, the housing assembly 700 includes a housing body 710, an inner cover 720, and an outer cover 730. The housing body 710 has at least one receiving opening 711. The inner cover 720 and the outer cover 730 are disposed from the inside to the outside at the receiving opening 711. The drive assembly 300 is clamped and disposed between the inner cover 720 and the outer cover 730. Through the arrangement of the inner cover 720 and the outer cover 730, the drive assembly 300 can be moved along the axis B of the receiving cavity 110 to ensure that it rotates around the axis.

[0044] In some embodiments, the inner cover 720 and the outer cover 730 are provided with a through hole 740 along the axis B of the receiving cavity 110. One end of the drive assembly 300 passes through the through hole 740 and is flush with the end face of the outer cover 730. The end of the drive assembly 300 is exposed outside the housing assembly 700, which facilitates the user to operate the rotating assembly to rotate. The end of the drive assembly 300 and the end face of the outer cover 730 are flush, which facilitates the placement of the generating device.

[0045] Please continue reading. Figure 6In some embodiments, the outer periphery of the drive assembly 300 (rotating disk 310) is provided with a stepped structure 330. The inner cover 720 and the outer cover 730 respectively abut against the two stepped surfaces of the stepped structure 330. Then, through the action of other components in the generating device, the drive assembly 300 is fixed in the axial direction B of the receiving cavity 110. Specifically, the inner cover 720 and the outer cover 730 are inserted into the housing body 710 through the receiving opening 711 and the receiving opening 711 is sealed. A groove can be formed between the inner cover 720 and the outer cover 730, and the stepped structure 330 of the drive assembly 300 is fixed in the groove.

[0046] Please see Figure 7 In some embodiments, the aerosol generating device further includes a movable support 800, which is disposed outside the movable base 200 and the drive assembly 300. The movable support 800 has a movable groove 810 along the axis B of the receiving cavity 110. The movable base 200 has a movable block 210, which is slidably connected to the movable groove 810. The movable groove 810 further limits the movement trajectory of the movable base 200, ensuring stable operation along the axis B of the receiving cavity 110.

[0047] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
