Aerosol generating apparatus for heated tobacco product

Abstract

The present application discloses an aerosol generating apparatus for a heated tobacco product. The aerosol generating apparatus comprises a heating structure, a wire, a first graphite structure, and a second graphite structure. The first graphite structure and the second graphite structure are stacked such that airflow can enter an airflow channel of the first graphite structure via the second graphite structure. The first graphite structure is further provided with an accommodation cavity for accommodating the heating structure, and the second graphite structure is provided with a first end part adjacent to the first graphite structure. One end of the wire is connected to the heating structure, and the other end of the wire either passes through an edge of the first end part of the second graphite structure to an outer side, or passes through a wiring through-hole on the second graphite structure to the outer side, the wiring through-hole being offset from a central axis of the accommodation cavity. Thus, the wire is prevented from being routed under the accommodation cavity of the first graphite structure, reducing the adhesion of diffused aerosol to the wire, thereby mitigating carbon buildup below the accommodation cavity of the first graphite structure, ensuring that the whole air channel remains unobstructed, and allowing airflow to smoothly enter the airflow channel.

Description

TECHNICAL FIELD

[0001] Embodiments of the present application relates to the field of heating appliance technologies, and in particular, to a heated cigarette aerosol-generating device.BACKGROUND

[0002] Smoking products (for example, cigarettes, cigars, or the like) burn tobaccos during use to produce tobacco smoke for people to inhale. During burning, while nicotine and other active ingredients are released, the smoking product generates toxic and carcinogenic substances such as tar and carbon monoxide due to incomplete burning or the like. These substances are proved to be main cause of health problems for smokers. Attempts have been made to provide alternatives to these tobacco-burning articles by creating products that release compounds such as nicotine without burning, so as to reduce hazards of smoking. Examples of such products are so-called heat-not-burn products which release the active compounds such as nicotine by heating the smoking products rather than burning the smoking products. Since no burning occurs, the toxic and carcinogenic substances such as tar and carbon monoxide in the smoke are greatly reduced.

[0003] An example of such a product is a heating device that releases the compound by heating a material rather than burning a material. Inhalable aerosol is generated by heating an aerosol product.

[0004] In the prior art, during use, the aerosol generated after heating can be diffused in the whole heating device, a heating structure needs to be connected to a power unit or other functional units through wires, and the diffused aerosol can gradually adhere to the wires, and then, carbon deposits that accumulate into clumps is formed, resulting in blockage of an air inlet space, which can affect air inflow, so that the whole heating device cannot be used normally.SUMMARY

All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0023] The terms such as "first", "second" and "third" in the present application are used herein for purposes of description and are not intended to indicate or imply relative importance or significance or to imply the number or order of indicated technical features. All directional indications (such as up, down, left, right, front, rear, ...) in the embodiments of the present application are only used to illustrate the relative position relationship between the components, the movement situation of the components, or the like, in a specific posture (as shown in the drawing), and if the specific posture is changed, the directional indications are changed accordingly. In addition, the terms "include" and "have" as well as any variants thereof are intended to cover a non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes other steps or units not listed or inherent in such process, method, product, or device.

[0024] Reference herein to "embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the present application. The appearances of such phrase in various places in the description / specification does not necessarily refer to the same embodiment, nor it is an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0025] It should be noted that when an element is referred to as being "fixed on" another element, the element may be directly located on the other element or an intermediate element may exist. When one element is considered to be "connected" to another element, it may be directly connected to the another element or one or more intermediate elements may co-exist therebetween. The terms "vertical", "horizontal", "left", "right", and similar expressions used herein are for illustrative purposes only, and do not indicate unique implementations.

[0026] Referring to FIG. 1 to FIG. 10, an embodiment of the present application provides an aerosol-generating device, including a heating structure 30, a wire 90, a first graphite structure 40, and a second graphite structure 50. The heating structure 30 is arranged in an accommodating cavity 41 of the first graphite structure 40 to heat the first graphite structure 40, and then, heat is transferred from the first graphite structure 40 to an airflow channel 42 arranged on the first graphite structure 40. When airflow flows through the airflow channel 42, the airflow may be heated to high temperature airflow which can heat an aerosol-generating product to produce aerosol for inhalation. The heating structure 30 may be connected to a power unit or other functional unit by the wire 90. The wire 90 is routed from the outer side of the second graphite structure 50 and connected to the heating structure 30. Compared with other routing modes such as central routing, the wire 90 routed from the outer side of the first graphite structure 40 can reduce adhesion of the diffused aerosol to the wire because the wire 90 does not extend below the accommodating cavity 41 of the first graphite structure 40, thereby reducing carbon deposition, and therefore reducing the blockage of an air inlet space caused by carbon deposition. An expected service life of the aerosol-generating device according to the embodiment of the present application may be prolonged.

[0027] Specifically, referring to the embodiment illustrated by FIG. 3 and FIG. 4, one end of the wire is connected to the heating structure, and the other end of the wire passes through an edge of a first end portion of the second graphite structure 50 adjacent to the first graphite structure 40 to the outer side of the second graphite structure. That is, the wire is routed between the first graphite structure 40 and the second graphite structure 50 to the outer side. Alternatively, referring to the embodiment illustrated by FIG. 7 and FIG. 8, the one end of the wire 90 is connected to the heating structure, the other end of the wire passes through a routing through hole 54 in the second graphite structure 50 to the outer side of the second graphite structure 50. An axis of the routing through hole 54 is offset from a central axis of the accommodating cavity 41. Since the routing through hole 54 is offset from the central axis of the accommodating cavity 41, the wire 90 is not routed below the first graphite structure 40. Smoothness of an inlet of the airflow channel 42 is avoided from being affected by the wire 90 being routed below the first graphite structure 40 during use. The reason is that if the wire is routed below the first graphite structure 40, the aerosol will be adhered to the wire 90 located below the accommodating cavity, resulting in the formation of carbon deposits that accumulate into clumps, thereby block the inlet of the airflow channel 42. Secondly, the wire 90 located in a cavity below the structure is more likely to be adhered by the aerosol than the wire 90 routed on the outer side, thereby aggravating carbon deposition.

[0028] In some embodiments, referring to FIG. 3 to FIG. 6, a through hole 521 configured for limiting is arranged in the first graphite structure 40 and / or the second graphite structure 50. The through hole 521 can limit the wire 90 to a certain extent, so that the wire 90 can be routed along the outer side of the first graphite structure 40 instead of below it. The through hole 521 may be provided in a side wall 52 of the first graphite structure 40, or the edge of the first end portion of the second graphite structure 50 adjacent to the first graphite structure 40. The through holes 521 can alternatively be provided in both the side wall 52 of the first graphite structure 40 and the edge of the first end portion, as long as the through holes 521 in the first graphite structure 40 and the second graphite structure 50 can be aligned with each other when the two graphite structures are stacked.

[0029] In some embodiments, referring to FIG. 9 and FIG. 10, a gap though which wire 90 passes is formed between the first graphite structure 40 and the second graphite structure 50. The one end of the wire is connected to the heating structure and the other end of the wire passes through the gap and extends out from the edge of the first end portion of the second graphite structure 50.

[0030] In some embodiments, referring to FIG. 6, a routing groove 43 is provided in a second end portion of the first graphite structure 40 adjacent to the second graphite structure 50. The wire 90 can pass through a routing notch to be connected to the heating structure 30 along the routing groove 43. The routing groove 43 can limit the wire 90. Meanwhile, since the wire 90 is located in the routing groove 43, a contact area between the wire 90 and the aerosol is reduced, thereby further reducing the adhesion of the aerosol to the wire 90.

[0031] In some embodiments, referring to FIG. 3, FIG. 4, and FIG. 6, the accommodating cavity 41 is arranged in a central region of the first graphite structure 40, and two or more airflow channels 42 are arranged around the accommodating cavity 41. The heating structure 30 located in the accommodating cavity 41 heats the airflow flowing through the airflow channels 42 via the first graphite structure 40. An airflow outlet 511 of the second graphite structure 50 is arranged in the first end portion thereof adjacent to the first graphite structure 40 when the first graphite structure 40 and the second graphite structure 50 are stacked. The airflow outlet 511 can cover inlets of all the airflow channels 42 and is in communication with the airflow channels 42, so that the inlets of the airflow channels 42 cannot be obstructed by the second graphite structure 50, and the smooth airflow is ensured.

[0032] In some embodiments, referring to FIG. 3 to FIG. 6, a base 60 is further included. The base 60 includes an annular wall surface 61, an axial air outlet through hole 63, and a lateral air inlet through hole 62. The annular wall surface 61 is provided with a hollow first cavity. The lateral air inlet through hole 62 is provided in the annular wall surface 61 and is in communication with the first cavity. The axial air outlet through hole 63 is adjacent to a third end portion of the second graphite structure 50. The airflow may enter the first cavity via the lateral air inlet through hole 62, then enter the second graphite structure 50 via the axial air outlet through hole 63, and then enter the first graphite structure 40 via the airflow outlet in the first end portion of the second graphite structure 50. This channel route may serve as a first air inlet airflow channel 42.

[0033] In some embodiments, referring to FIG. 5 and FIG. 6, the lateral air inlet through hole 62 is in a vertical strip shape and extends along an axial direction of the second graphite structure 50. The vertical strip-shaped lateral air inlet through hole 62 can further mitigate carbon deposits that accumulate into clumps. Due to gravity of carbon deposits that accumulate into clumps or the like, carbon deposits that accumulate into clumps at the bottom of the lateral air inlet through hole 62 may be more serious than those at the top of the lateral air inlet through hole 62. By the arrangement of the vertical strip-shaped lateral air inlet through hole 62, a larger ventilation space in the axial direction can be allowed, and even if the bottom of the lateral air inlet through hole 62 is blocked by carbon deposits that accumulate into clumps, the top of the lateral air inlet through hole 62 can still be kept unblocked.

[0034] In some embodiments, referring to FIG. 3 to FIG. 6, the base 60 further includes an axial air inlet through hole 64 that is opposed to the axial air outlet through hole 63. The axial air inlet through hole 64 is in communication with the first cavity. The airflow may enter the first cavity via the axial air inlet through hole 64 and then flows through the axial air outlet through hole 63 to enter an airflow inlet 512 in the third end portion of the second graphite structure 50. This channel route may serve as a second air inlet airflow channel 42.

[0035] In some embodiments, referring to FIG. 4, the second graphite structure 50 is arranged between the first graphite structure 40 and the base 60. An interspace is provided between the base 60 and the third end portion of the second graphite structure 50, and the airflow can also directly enter the second graphite structure 50 via the interspace. This channel route may serve as a third air inlet airflow channel 42.

[0036] In some embodiments, referring to FIG. 3 to FIG. 6, the first graphite structure 40 and the second graphite structure 50 are movably connected together by a fixing member 70.

[0037] In some embodiments, referring to FIG. 3 to FIG. 6, a first clamping part 71 and a second clamping part 72 of the fixing member 70 collectively clamp the first graphite structure 40 and the second graphite structure 50. The fixing member 70 is further provided with an axial limiting member 73. The axial limiting member 73 abuts against the third end portion of the second graphite structure 50 to limit an axial position of the second graphite structure 50 relative to the first graphite structure 40. The axial limiting member 73 may be located only on the first graphite structure 40 or the second graphite structure 50, or may be located on both the first graphite structure 40 and the second graphite structure 5. FIG. 5 to FIG. 6 show an embodiment in which two limiting members are located on the first graphite structure 40 and the second graphite structure 50 respectively. After the first clamping part 71 and the second clamping part 72 clamp the first graphite structure 40 and the second graphite structure 50 together, the fixing member 70, together with the first graphite structure 40, and the second graphite structure 50 is sheathed by an annular tube 80, so that the first clamping part 71 and the second clamping part 72 cooperate with each other to limit a radial position of the second graphite structure 50 relative to the first graphite structure 40.

[0038] In some embodiments, the fixing member 70 further includes an extension supporting leg. The extension supporting leg extends from the first clamping part 71 and / or the second clamping part 72 and abuts against the base 60, so that the interspace through which the airflow can flow through is formed between the base 60 and the second graphite structure 50. The extension supporting leg may extend from the first clamping part 71 or the second clamping part 72, or extension supporting legs may extend from both the first clamping part 71 and the second clamping part 72. FIG. 5 to FIG. 6 show an embodiment in which two extension supporting legs extend from the first clamping part 71 and the second clamping part 72 respectively.

[0039] In some embodiments, as shown in FIG. 5, a temperature measuring element 53 is further included and arranged on the second graphite structure 50. Specifically, the second graphite structure 50 includes a pedestal 51. A side wall 52 extends from the pedestal 51 towards the first graphite structure 40, and a second cavity through which the airflow can flow through is formed between the pedestal 51 and the side wall 52. The temperature measuring element 53 is arranged on the pedestal 51, and a probe part thereof faces the first graphite structure 40. As such, when a user inhales, the airflow flows from the second cavity of the second graphite structure 50 into the airflow channel 42 of the first graphite structure 40, and in this case, a temperature of the newly inhaled airflow is relatively low due to flowing of the airflow, so that the temperature detected by the probe part of the temperature measuring element 53 will change significantly, thereby being able to detect the number of times of inhalation. The temperature measuring element 53 includes, but is not limited to, a thermocouple.

[0040] In some embodiments, referring to FIG. 4, the annular tube 80 includes a fixed protrusion. The fixed protrusion 81 protrudes inwards from an inner wall surface of the annular tube 80, and divides a receiving cavity of the annular tube 80 into a first cavity part and a second cavity part. The first cavity part may be configured to receive an aerosol-generating product such as a cigarette 100. The fixing member 70, the first graphite structure 40, and the second graphite structure 50 are located in the second cavity part. During mounting, an end surface of the fixing member 70 abuts against the fixed protrusion 81.

[0041] It should be noted that preferred embodiments of the present application are given in the specification and the drawings of the present application, but the present application is not limited to the embodiments described in the specification. Further, for those ordinary skilled in the art, improvements or variants can be made based on the above description, and all such improvements and variants should fall within the protection scope of the appended claims of this application.
