Description

Technical Field

[0001] This invention relates to the field of aerosol generating devices, and particularly to an aerosol generating device and its method of use. Background Technology

[0002] As an option for consumers to reduce the harm caused by traditional tobacco, novel aerosol-generating products have seen rapid development in recent years. Common aerosol-generating products can be broadly categorized according to the form of the aerosol-generating materials, such as e-cigarettes and heated cigarettes. E-cigarettes use liquid materials to generate aerosols, while heated cigarettes use solid materials, such as tobacco sheets, tobacco particles, shredded tobacco, and reconstituted tobacco. In other words, aerosol-generating products include solid materials that generate aerosols, i.e., solid tobacco media.

[0003] For example, during normal use of solid tobacco media, it is heated to above 200°C without combustion, thereby avoiding the inhalation of harmful components produced by combustion and high-temperature (up to 800°C) degradation of traditional tobacco products. This aerosol-generating product containing solid smoke-generating materials structurally includes a smoke-generating unit, a cooling unit, a filtering unit, and a coating unit. The smoke-generating unit is the matrix for generating inhalable aerosols by the heating unit, and can be the aforementioned tobacco sheets, tobacco particles, etc.

[0004] Based on the form of the heating element, commercially available aerosol generating devices are mainly divided into two types: internal heating and external heating. These devices have a receiving section, which includes a cavity for inserting the aerosol generating product, thus accommodating it. If internal heating is used, the heating element (such as a heating needle or heating plate) extends into the receiving section and is inserted into the smoke-generating unit of the aerosol generating product, forming an aerosol through heat conduction from within the smoke-generating unit. If external heating is used, the heating element (such as a heating ring or heating wire) is positioned on the inner wall of the receiving section and surrounds the aerosol generating product, forming an aerosol through heat conduction from outside the smoke-generating unit.

[0005] Currently, aerosol generating devices on the market, once the heating element is determined and designed, are often only compatible with a single type of aerosol generating product. The suction resistance is also fixed due to the structural design, failing to adapt to the diverse needs of different consumers. Furthermore, the development of new products requires testing with different specifications of aerosol generating products and varying suction resistance parameters. If parameters cannot be adjusted, frequent changes to the aerosol generating device during experiments significantly reduce development efficiency. Summary of the Invention

[0006] The purpose of this invention is to solve the technical problem that existing aerosol generating devices cannot be adapted to a variety of aerosol generating products of different specifications.

[0007] In a first aspect, embodiments of the present invention disclose an aerosol generating apparatus, including a receiving portion for accommodating an aerosol generating article, and further including a length adapting device for the aerosol generating article, wherein the length adapting device includes:

[0008] An adjusting rod extends along a first direction, which is consistent with the extension direction of the aerosol generating article. The adjusting rod can be inserted into the receiving part that contains the aerosol generating article along the first direction. The end face of the adjusting rod located in the receiving part is used to support the aerosol generating article.

[0009] The operating part, connected to the length adjustment rod, is used to drive the length adjustment rod to move in a first direction to adjust the insertion length of the length adjustment rod in the receiving part.

[0010] Because this invention incorporates a length adaptation device in the aerosol generating apparatus, the length of the heated aerosol generating product can be easily adjusted to accommodate different types of aerosol generating products. For example, during testing, the aerosol generating product to be tested can be placed in the receiving section, and the operating section can be adjusted according to the length of the smoke-generating unit of the aerosol generating product. For instance, when the length adaptation device needs to be changed from adapting to an aerosol generating product with a smoke-generating unit length of 10cm to adapting to an aerosol generating product with a smoke-generating unit length of 12cm, the operating section needs to be adjusted so that the length adjustment rod moves downwards along the first direction. Since the aerosol generating product is placed at the end of the length adjustment rod, the downward movement of the length adjustment rod increases the upper limit of the length of the aerosol generating product placed in the receiving section in the first direction, from 10cm to 12cm. At this time, the smoke-generating unit of the aerosol generating product can be completely placed in the receiving section, thus completing the adaptation of the smoke-generating unit length. The length adaptation device of this invention enables the testing of aerosol generating products with different smoke-generating unit lengths within the same device. This eliminates the need to change the aerosol generating device used to house the aerosol generating products when testing different models, thus improving the applicability of the aerosol generating device and facilitating the development of new products. Furthermore, the length adjustment rod includes a first vent hole penetrating the rod; the operating part includes:

[0011] Multiple second vent holes with different diameters;

[0012] The aperture adjustment section is used to select a second vent with a corresponding aperture that communicates with the first vent. The first vent and the second vent form at least a portion of an airflow channel communicating with the outside.

[0013] Since the aerosol generating device of the present invention also provides multiple second vents with different apertures, when it is necessary to adjust the suction resistance parameter for testing aerosol-generating products, simply operate the aperture adjustment unit to select the second vent with the corresponding aperture to adjust the air intake and thus achieve the purpose of adjusting the suction resistance parameter. Therefore, by using the aerosol generating device of the present invention, not only can it be adapted to the length of the smoke-generating unit of different aerosol-generating products, but it can also adjust the suction resistance parameter when testing aerosol-generating products, thereby improving R&D efficiency and meeting the needs of different consumers.

[0014] Furthermore, the first vent extends along the first direction.

[0015] Furthermore, the operating part is used to move circumferentially to drive the length adjustment lever to move in a first direction, circumferentially around the first direction.

[0016] Furthermore, the length adjustment rod includes an upper rod body and a lower rod body distributed along a first direction. The lower rod body is threadedly connected to the operating part, and the upper rod body cooperates with a limiting device to make the length adjustment rod move along the first direction when the operating part moves in the circumferential direction.

[0017] Furthermore, the outer periphery of the upper rod body is provided with at least one rotation limiting groove, the rotation limiting groove extends along the first direction, and the limiting device is a rib, which is located in the rotation limiting groove.

[0018] Furthermore, the outer surface of the lower rod body is provided with external threads, and the operating part includes an air regulating rod. The inner wall of the air regulating rod is provided with an internal thread that mates with the external threads. The air regulating rod can move in the circumferential direction but does not move in the first direction.

[0019] Furthermore, the operating unit also includes an operating lever, which is sleeved on the outer surface of the air regulating rod and is used to drive the air regulating rod to rotate circumferentially.

[0020] Furthermore, the air regulating rod has multiple second vent holes of different diameters distributed circumferentially; the operating rod has a third vent hole and a seal, and the operating rod can switch between a first position and a second position;

[0021] In the first position, the operating lever can rotate circumferentially relative to the air regulating lever so that the third vent is connected to the second vent of the corresponding diameter. The seal rotates synchronously with the operating lever circumferentially. The second vent, the third vent, and the first vent penetrating the length regulating lever form at least a part of the airflow channel communicating with the outside.

[0022] In the second position, the operating lever is fixedly connected to the air regulating lever, and the sealing element can seal the second air vents that are not connected to the third air vent among multiple second air vents of different diameters.

[0023] Furthermore, the operating lever can be separated from the air regulating lever in the first direction to switch from the second position to the first position.

[0024] Furthermore, the air regulating rod is provided with a flow component, which has multiple second vent holes of different diameters. The flow component and the inner wall of the air regulating rod form a sealing element receiving part.

[0025] The seal includes a fourth vent and a first limiting portion, and the seal is located within the seal receiving portion;

[0026] The operating lever is provided with a second limiting part, which cooperates with the first limiting part to make the sealing element and the operating lever rotate synchronously in the circumferential direction. The third vent hole is connected to the fourth vent hole. The end of the sealing element is attached to the flow component to seal the second vent hole that is not connected to the third vent hole among the multiple second vent holes of different diameters.

[0027] Furthermore, the first limiting part and the second limiting part are in a concave-convex fit;

[0028] In the first position and the second position, at least a portion of the seal is located within the seal receiving portion. In the first position, the second limiting portion is capable of separating from the first limiting portion along a first direction.

[0029] Furthermore, the operating lever is provided with a first limiting structure, and the operating part also includes: an elastic member, one end of which abuts against one end of the first limiting structure along the first direction, and the other end abuts against the external component installed on the length adaptation device. The elastic member can be compressed to separate the operating lever from the air regulating rod along the first direction. In the second position, the other end of the first limiting structure abuts against the air regulating rod to drive the air regulating rod to rotate synchronously in the circumferential direction.

[0030] Furthermore, the elastic element is sleeved on the outer surface of the operating lever.

[0031] Furthermore, the air regulating rod is provided with a second limiting structure. In the second position, the first limiting structure and the second limiting structure are in concave-convex cooperation to achieve synchronous circumferential rotation.

[0032] Furthermore, along the first direction, one of the first limiting structure and the second limiting structure is provided with a limiting protrusion, and the other is provided with a limiting groove that cooperates with the limiting protrusion.

[0033] Furthermore, the length adjustment rod is also provided with a third limiting structure, which is used to abut against the external component installed on the length adaptation device along the first direction, so as to limit the distance the length adjustment rod moves along the first direction.

[0034] Furthermore, the receiving part is a heating element used to heat the aerosol-generating product placed in the heating element.

[0035] Secondly, embodiments of the present invention also disclose a method of using the aerosol generating apparatus described in any of the first aspects above, including:

[0036] Provide an aerosol generating product, wherein the smoke generating unit of the aerosol generating product is placed in the receiving part of the aerosol generating device, and the end face of the length adjustment rod of the aerosol generating device located in the receiving part supports the smoke generating unit of the aerosol generating product.

[0037] The operating part of the aerosol generating device drives the length adjustment rod to move in the first direction so that the receiving part completely accommodates the smoke generating unit of the aerosol generating product.

[0038] The method of using the aerosol generating device of the present invention involves driving the operating unit to move the adjusting rod upwards or downwards along a first direction to adjust the insertion length of the adjusting rod in the receiving part, so that the receiving space defined by the receiving part and the adjusting rod in the aerosol generating device is adapted to the length of the smoke-generating unit of the aerosol generating article. That is, by moving the adjusting rod upwards or downwards along the first direction, the length of the receiving space in the first direction can be adjusted to fully accommodate the smoke-generating unit. For example, if the length of the smoke-generating unit is 10cm, the length of the receiving space should also be adjusted to 10cm accordingly. Thus, a variety of aerosol generating articles with different design parameters (e.g., smoke-generating units of different lengths) can be tested with a single aerosol generating device, which can improve the applicability of the aerosol generating device of the present invention and improve the efficiency of laboratory research and development.

[0039] Furthermore, the aperture adjustment section of the aerosol generating device can be operated to select a second vent hole of a corresponding aperture that communicates with the first vent hole of the aerosol generating device. The first vent hole and the second vent hole form at least a part of an airflow channel communicating with the outside.

[0040] The method of using the aerosol generating device of the present invention not only allows adjustment of the length of the aerosol-generated product contained in the device, but also adjusts the suction resistance parameters when testing the aerosol-generated product. For example, when the initially selected second vent diameter is 0.8 cm, if a larger suction resistance parameter needs to be tested, the vent diameter adjustment unit can be operated to select a second vent with a smaller diameter, such as a second vent with a diameter of 0.5 cm. This reduces the diameter of the airflow channel communicating with the outside, achieving the purpose of testing a larger suction resistance parameter. This method is simple to operate and can further improve the efficiency of new product development.

[0041] Thirdly, embodiments of the present invention also disclose an aerosol generating apparatus, including a receiving portion for accommodating an aerosol generating article and a gas volume regulating device for the aerosol generating apparatus, wherein the gas volume regulating device includes:

[0042] The first vent is able to communicate with the container that holds the aerosol-generating product;

[0043] The operating unit includes:

[0044] Multiple second vent holes with different diameters;

[0045] The aperture adjustment section is used to select a second vent with a corresponding aperture that communicates with the first vent. The first vent and the second vent form at least a portion of an airflow channel communicating with the outside.

[0046] Because the aerosol generating device of the present invention is equipped with a gas flow regulating device, using the aerosol generating device of the present invention allows for convenient adjustment of suction resistance parameters when testing suction resistance in the laboratory, thereby improving R&D efficiency and meeting the needs of different consumers. For example, the gas flow regulating device of the present invention provides multiple second vents with different orifice diameters. When it is necessary to adjust the suction resistance parameters for testing aerosol-generated products, simply operate the orifice diameter adjustment unit to select the second vent with the corresponding orifice diameter to adjust the air intake and thus achieve the purpose of adjusting the suction resistance parameters.

[0047] Furthermore, the gas volume regulating device includes:

[0048] An air regulating rod extends along a first direction, which is consistent with the extension direction of the aerosol generating product. The air regulating rod has a plurality of second vent holes of different diameters distributed circumferentially around the first direction.

[0049] The control lever is sleeved on the outer surface of the air regulating rod. The control lever has a third vent hole and a sealing element. The control lever can switch between a first position and a second position.

[0050] In the first position, the operating lever can rotate circumferentially relative to the air regulating lever so that the third vent is connected to the second vent of the corresponding diameter. The seal rotates synchronously with the operating lever in the circumferential direction, and the first vent, the second vent, and the third vent form at least a part of the airflow channel communicating with the outside.

[0051] In the second position, the operating lever is fixedly connected to the air regulating lever, and the sealing element seals the second air vent among multiple second air vents of different diameters that are not connected to the third air vent.

[0052] Furthermore, the operating lever can be separated from the air regulating lever in the first direction to switch from the second position to the first position.

[0053] Furthermore, the air regulating rod is provided with a flow component, which has multiple second vent holes of different diameters. The flow component and the inner wall of the air regulating rod form a sealing element receiving part.

[0054] The seal includes a fourth vent and a first limiting portion, and at least a portion of the seal is located within the seal receiving portion;

[0055] The operating lever is provided with a second limiting part, which cooperates with the first limiting part to make the sealing element and the operating lever rotate synchronously in the circumferential direction. The third vent hole is connected to the fourth vent hole. The end of the sealing element is attached to the flow component to seal the second vent hole that is not connected to the third vent hole among the multiple second vent holes of different diameters.

[0056] Furthermore, the first limiting part and the second limiting part are in a concave-convex fit;

[0057] In the first position and the second position, the seal is located within the seal receiving portion. In the first position, the second limiting portion is capable of separating from the first limiting portion along a first direction.

[0058] Furthermore, the operating lever is provided with a first limiting structure, and the air volume regulating device also includes: an elastic element, one end of which abuts against one end of the first limiting structure along the first direction, and the other end abuts against the external component on which the air volume regulating device is installed, and the elastic element can be compressed to separate the operating lever from the air regulating lever along the first direction.

[0059] Fourthly, the present invention also discloses a method of using the aerosol generating apparatus disclosed in the third aspect above, comprising:

[0060] Provides an aerosol generating article, which is placed in the receiving part of the aerosol generating device;

[0061] Operate the aperture adjustment section of the aerosol generating device to select a second vent with a corresponding aperture that communicates with the first vent of the aerosol generating device. The first vent and the second vent form at least a portion of an airflow channel communicating with the outside.

[0062] The method of using the aerosol generating device of the present invention allows for easy adjustment of the draw resistance parameters when testing aerosol-generating products for different draw resistance parameters. Simply place the aerosol-generating product to be tested in the receiving section of the aerosol generating device, and then adjust the orifice adjustment section to select the appropriate second vent according to the testing requirements. For example, if the initially selected second vent diameter is 1.1 cm, and a smaller draw resistance parameter needs to be tested, simply adjust the orifice adjustment section to select, for example, a second vent diameter of 1.4 cm. This increases the orifice diameter of the airflow channel connecting the first and second vents, thus achieving the goal of testing a smaller draw resistance parameter. This allows for easy testing of the draw resistance parameters of aerosol-generating products in the laboratory, which is helpful for researchers developing new tobacco products.

Those skilled in the art can understand the specific meaning of the above terms in this embodiment based on the specific circumstances.

[0089] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0090] refer to Figures 1 to 2 This application provides an aerosol generating apparatus 130, including a receiving portion for accommodating an aerosol generating article 100 and a length adapting device for the aerosol generating article 100. The length adapting device includes an adjusting rod 40 and an operating portion 110. The adjusting rod 40 extends along a first direction, which is... Figure 1 and Figure 2 The first direction is aligned with the extension direction of the aerosol generating article 100. The adjusting rod 40 can be inserted into the receiving portion that accommodates the aerosol generating article 100 along the first direction. The end face of the adjusting rod 40 located within the receiving portion is used to support the aerosol generating article 100. The operating part 110 is connected to the adjusting rod 40 and is used to drive the adjusting rod 40 to move along the first direction to adjust the insertion length of the adjusting rod 40 within the receiving portion.

[0091] In this invention, the receiving portion refers to the part within the aerosol generating device 130 used to receive the aerosol generating article 100 during normal use of the aerosol generating device 130. During the process of adjusting the length adapter to test different aerosol generating articles 100, the length of the receiving portion that can accommodate the aerosol generating article 100 in the first direction changes accordingly with the length of the length adjustment rod 40 inserted into the receiving portion.

[0092] For example, during testing, the aerosol generating product 100 to be tested can be placed in the receiving section, and the operating section 110 can be adjusted according to the length of the smoke-generating unit of the aerosol generating product 100. For instance, when the length adaptation device of the present invention needs to be changed from adapting to an aerosol generating product 100 with a smoke-generating unit length of 10cm to adapting to an aerosol generating product 100 with a smoke-generating unit length of 12cm, the operating section 110 needs to be adjusted so that the length adjustment rod 40 moves downward in the first direction. Since the aerosol generating product 100 is placed at the end of the length adjustment rod 40, the downward movement of the length adjustment rod 40 increases the length of the aerosol generating product 100 that can be placed in the receiving section in the first direction, allowing the smoke-generating unit of the aerosol generating product 100 to be completely placed in the receiving section, thus completing the adaptation of the smoke-generating unit length. By using the length adaptation device of the present invention, aerosol generating products 100 with different smoke generating unit lengths can be tested in the same device without changing the aerosol generating device 130 that holds the aerosol generating products when testing different models of aerosol generating products 100. This can improve the applicability of the aerosol generating device 130 and facilitate the research and development of new products.

[0093] Specifically, in some embodiments of this application, the operating part 110 is used to move circumferentially to drive the length adjusting lever 40 to move in a first direction, circumferentially ( Figure 1The length adjustment lever 40 moves in the first direction (in the X direction). That is, the operation unit 100 converts the circumferential motion into linear motion in the first direction. It should be noted that this application does not limit the formation of the method of driving the length adjustment lever to move in the first direction. In some possible embodiments, the length adjustment lever can be driven to move in the first direction by the operation unit moving in the first direction.

[0094] Furthermore, in this embodiment, the adjusting rod 40 is cylindrical. In some other possible embodiments, the adjusting rod may also be square or other shapes. This application does not limit the shape and specifications of the adjusting rod, as long as it can be placed in the external component of the aerosol generating article and driven by the operating part to move in the first direction. In the embodiments of the present invention, the external component of the aerosol generating article 100 refers to the housing of the aerosol generating device 130.

[0095] In some embodiments of this application, reference is made to Figure 4 The length adjustment rod 40 includes an upper rod body 41 and a lower rod body 43 distributed along a first direction. The lower rod body 43 is threadedly connected to the operating part 110, and the upper rod body 41 cooperates with a limiting device, enabling the length adjustment rod 40 to move along the first direction when the operating part 110 moves circumferentially. The threaded connection between the lower rod body and the operating part can be either an external thread on the outer surface of the lower rod body engaging with an internal thread in the operating part, or an internal thread in the lower rod body engaging with an external thread on the outer surface of the operating part. This application does not limit the manner in which the lower rod body and the operating part are threaded together.

[0096] In this embodiment, the upper rod 41 and the lower rod 43 are integrally formed. In some other possible embodiments, the upper rod and the lower rod can also be detachably connected, for example by threaded connection or snap-fit. This application does not limit the connection method of the upper and lower rods in the length adjustment rod, as long as the upper rod and the lower rod can be fixedly connected and achieve synchronous movement.

[0097] In some other possible embodiments, the movement of the length adjusting rod along the first direction driven by the circumferential movement of the operating part can also be accomplished by a structure similar to a lead screw, and is not limited to the threaded fit in this embodiment.

[0098] This application does not limit the specific type of the aforementioned limiting device; any form capable of limiting the circumferential movement of the adjusting rod falls within the protection scope of this application. For example, in some embodiments of this application, refer to... Figure 3 and Figure 4The upper rod body 41 has at least one limiting rotation groove 411 on its outer periphery, which extends along a first direction. The limiting device is a rib 11, which is located inside the limiting rotation groove 411 and is used to cooperate with the limiting rotation groove 411 so that when the operating part 110 moves in the circumferential direction, the length adjustment rod 40 does not move in the circumferential direction. In other words, the rib 11 and the limiting rotation groove 411 are in a concave-convex fit to limit the circumferential movement of the operating part 110.

[0099] Specifically, in this embodiment, reference is made to... Figure 3 and Figure 4 The limiting device is the heating element support 10 in the aerosol generating device 130. The heating element support 10 has three circumferentially spaced ribs 11. Correspondingly, the upper rod body 41 of the adjusting rod 40 has three limiting rotation grooves 411 extending in the first direction. In some other possible embodiments, the adjusting rod may also be provided with one, two, four, or other numbers of limiting rotation grooves, and the heating element support may also be provided with one or more ribs corresponding to the number of limiting rotation grooves on the adjusting rod. Here, the number of limiting rotation grooves and ribs is not limited, as long as they can limit the adjusting rod from circumferential movement.

[0100] Furthermore, in this embodiment, the limiting device, i.e., the heating element support 10, is part of the outer component of the aerosol generating device 130, which is installed on the aerosol generating article 100. It is used to support the heating element 90 disposed within the aerosol generating device 130. In this embodiment, the heating element 90 has a circular tubular structure, and during use, the heating element 90 is fixed within the aerosol generating device 130. In some other possible embodiments, the shape of the heating element can also be annular or other shapes. This application does not limit the shape of the heating element, as long as it can heat the aerosol generating article placed in the heating element.

[0101] For example, when the protruding ribs 11 on the heating element support 10 engage with the limiting rotation grooves 411 on the upper rod body 41, the length adjustment rod 40 can be restricted from rotating circumferentially. In this embodiment, the heating element support 10 is sleeved on the outer surface of the upper rod body 41, and the three protruding ribs 11 on the heating element support 10 are completely engaged in the three limiting rotation grooves 411 on the upper rod body 41. When the operating part 110 moves circumferentially, since the heating element support 10 is fixed relative to the housing of the aerosol generating device 130, the length adjustment rod 40 cannot move circumferentially and can only move in the first direction due to the engagement of the protruding ribs 11 and the limiting rotation grooves 411.

[0102] In this embodiment, reference Figure 4As shown in Figure 5, the outer surface of the lower rod body 43 of the adjusting rod 40 is provided with an external thread (not shown). The operating part 110 includes an air adjusting rod 50, the inner wall of which is provided with an internal thread (not shown) that mates with the external thread. The air adjusting rod 50 can move circumferentially but does not move in the first direction. As described above, the threaded engagement between the air adjusting rod and the lower rod body can also be an engagement between the external thread on the outer surface of the air adjusting rod and the internal thread inside the adjusting rod.

[0103] In this embodiment, reference Figure 2 As shown in Figure 5, the housing support 30 is also part of the aerosol generating device 130 and is fixed inside the aerosol generating device 130. One end of the gas regulating rod 50 abuts against the housing support 30. When the gas regulating rod 50 moves in the circumferential direction, due to the restriction of the housing support 30, the gas regulating rod 50 cannot move in the direction of the heating element support 10 in the first direction.

[0104] In this embodiment, reference Figure 1 A washer 20 is provided between the heating element support 10 and the housing support 30. The washer 20 is made of silicone and has a hole in the middle. When the adjusting rod 40 moves in the first direction, it can pass through the washer 20 and be press-fitted with the washer 20 to ensure good sealing of the airflow channel.

[0105] In use, when the air regulating rod 50 moves circumferentially, the mating threads cause the air regulating rod 50 to move the length regulating rod 40. The length regulating rod 40, under the influence of the limiting rotation groove 411 and the protruding rib 11, converts the circumferential motion into linear motion along the first direction. In other embodiments, this method of converting circumferential motion into linear motion is not limited, as long as the corresponding function is achieved.

[0106] In some embodiments of this application, reference is made to Figure 4 As shown in Figure 5, the length adjustment rod 40 includes a first vent 44 penetrating through the length adjustment rod 40; the operation unit 110 includes: a plurality of second vents 521 with different diameters and a diameter adjustment unit 120, the diameter adjustment unit 120 being used to select a second vent 521 of a corresponding diameter that communicates with the first vent 44, the first vent 44 and the second vent 521 forming at least a portion of an airflow channel communicating with the outside. In some embodiments of the invention, the size of the second vent 521 in the operation unit is fixed, and the corresponding second vent 521 needs to be selected by the diameter adjustment unit 120 to adjust the air intake. In some possible embodiments of the invention, during the selection of the second vent, the diameter adjustment unit can be adjusted to select one or more of the second vents, realizing multiple combinations of the selected second vents, i.e., the air intake. In some other possible embodiments, the air intake can also be achieved through the second vents whose diameters can be adjusted.

[0107] Specifically, in this embodiment, the adjusting rod 40 is provided with a first vent 44 extending in a first direction, so that the airflow path in the adjusting rod 40 is minimized. In this application, there are no restrictions on the number, extension direction and path of the first vent, as long as the external airflow can flow through the second vent and the first vent into the aerosol generating product.

[0108] In this embodiment, reference Figure 1 and Figure 2 The operating unit 110 also includes an operating lever 70, which is sleeved on the outer surface of the air regulating rod 50 and used to drive the air regulating rod 50 to rotate circumferentially. In some other possible embodiments, the operating lever may also be placed inside the air regulating rod. This application does not limit the shape of the operating lever or the relative position of the operating lever and the air regulating rod, as long as the operating lever can drive the air regulating rod to move circumferentially.

[0109] Referring to Figures 5 to 7, the air regulating rod 50 has multiple second vent holes 521 with different diameters distributed circumferentially. In this embodiment, the operating part 110 is provided with five second vent holes 521 with different diameters, namely 0.5cm, 0.8cm, 1.1cm, 1.4cm, and 1.7cm. This application does not limit the location, number, or size of the second vent holes, and they can be set according to actual needs. In this embodiment, to adjust the suction resistance parameter, i.e., the air intake volume, for example, if the initially selected second vent hole 521 has a diameter of 1.1cm, and a larger suction resistance parameter needs to be tested, the air intake volume needs to be reduced, and a second vent hole 521 with a smaller diameter needs to be selected, such as a second vent hole 521 with a diameter of 0.5cm or 0.8cm.

[0110] In some embodiments of this application, the operating lever 70 has a third vent 72 and a sealing element 60, and the operating lever 70 can switch between a first position and a second position. In this embodiment, the third vent 72 is located at the bottom of the operating lever 70. In some other possible embodiments, the third vent may also be located on the side of the operating lever. The present invention does not limit the shape, size, and location of the third vent, as long as it can communicate with the second vent to ensure that external airflow can enter the aerosol generating device.

[0111] In the first position, the operating lever 70 is circumferentially rotatable relative to the air regulating lever 50, so that the third vent 72 communicates with the second vent 521 of the corresponding diameter. The sealing member 60 rotates synchronously with the operating lever 70 in the circumferential direction. The second vent 521, the third vent 72, and the first vent 44 penetrating the adjusting lever 40 form at least a portion of an airflow channel communicating with the outside. In this application, the operating lever 70 is in a state of separation from the air regulating lever 50 in the aforementioned first position.

[0112] In the second position, the operating lever 70 is fixedly connected to the air regulating lever 50, and the sealing element 60 can seal the second vent 521 of multiple second vents 521 with different diameters that is not connected to the third vent 72.

[0113] In this embodiment, the seal 60 and the operating lever 70 are separate components. In some other possible embodiments, the seal and the operating lever may also be integrated. The present invention does not limit the position of the seal, as long as it can seal the unselected second vent hole at the second position.

[0114] In the second position, the operating lever 70 is fixedly connected to the air regulating lever 50. When the operating lever 70 rotates, it will cause the air regulating lever 50 to rotate as well. At this time, it is impossible to select the second vent 521 provided on the air regulating lever 50 to adjust the air intake or suction resistance parameters. Therefore, it is necessary to switch the operating lever 70 from the second position to the first position, so that the operating lever 70 is separated from the air regulating lever 50, and then the operating lever 70 moves circumferentially. The sealing member 60 moves circumferentially synchronously with the operating lever 70 to select the corresponding second vent 521 with different diameters. At this time, the circumferential movement of the operating lever 70 does not affect the air regulating lever 50. In some embodiments of this application, refer to Figure 1 and Figure 2 The operating lever 70 can be separated from the air regulating lever 50 along a first direction to switch from a second position to a first position. This application does not limit the form in which the operating lever switches between the first and second positions; for example, the switch from the second position to the first position can be restricted by rotation.

[0115] In some embodiments of this application, reference is made to Figure 1 and Figure 2As shown in Figures 5 to 7, the air regulating rod 50 is provided with a flow component 52, and multiple second vent holes 521 of different diameters are provided on the flow component 52. The flow component 52 and the inner wall of the air regulating rod 50 form a sealing element receiving portion. The sealing element 60 includes a fourth vent hole 61 and a first limiting portion, and at least a portion of the sealing element 60 is located within the sealing element receiving portion. The operating rod 70 is provided with a second limiting portion, which cooperates with the first limiting portion to allow the sealing element 60 and the operating rod 70 to rotate synchronously in the circumferential direction. The third vent hole 72 communicates with the fourth vent hole 61, and the end of the sealing element 60 is fitted with the flow component 52 to seal the second vent hole 521 of the multiple second vent holes 521 of different diameters that does not communicate with the third vent hole 72. In this embodiment, the flow component 52 is a partition disposed in the air regulating rod 50. However, the flow component 52 of this application is not limited to a partition, but can also be other elements that can provide an airflow channel, such as a diaphragm with holes. The size of the fourth vent 61 on the seal 60 is the same as that of the third vent 72 on the operating lever 70. In some other possible embodiments, the sizes of the fourth vent and the third vent may not be the same, as long as the third vent and the fourth vent can be selected to meet the requirements of the suction resistance parameter test when the operating lever is in the second position.

[0116] In some embodiments of this application, reference is made to Figure 2 As shown in Figures 6 and 7, the first and second limiting portions are in a concave-convex fit. In the first and second positions, the sealing member 60 is located within the sealing member receiving portion. In the first position, the second limiting portion can separate from the first limiting portion along a first direction. This invention does not limit the manner in which the first and second limiting portions are in a concave-convex fit, but it needs to be able to ensure that when the operating lever 70 switches from the second position to the first position, the sealing member 60 remains within the receiving portion, but the first and second limiting portions are not completely separated. Furthermore, in the first position, the operating lever 70 is separated from the air regulating lever 50. When the operating lever 70 moves circumferentially in the first position, the air regulating lever 50 does not move. Through the cooperation of the first limiting portion of the sealing member 60 and the second limiting portion of the operating lever 70, the operating lever 70 can drive the sealing member 60 to move circumferentially synchronously.

[0117] In this embodiment, the seal 60 is made of silicone. In other possible embodiments of this application, the seal may also be made of rubber, PVC, etc., as long as the second position can achieve a seal on the unselected second vent hole on the flow component.

[0118] In some embodiments of this application, reference is made to Figure 2As shown in Figures 6 and 7, the operating lever 70 is also provided with a first limiting structure 71. Furthermore, the length adapting device includes an elastic element 80. Along a first direction, one end of the elastic element 80 abuts against one end of the first limiting structure 71, and the other end abuts against the external component on which the length adapting device is installed. The elastic element 80 can be compressed to separate the operating lever 70 from the air regulating rod 50 along the first direction. In a second position, the other end of the first limiting structure 71 abuts against the air regulating rod 50 to drive the air regulating rod 50 to rotate synchronously in the circumferential direction. Here, the external component on which the length adapting device is installed also refers to the housing of the aerosol generating device. Exemplarily, the first limiting structure 71 can be a limiting flange provided on the operating lever 70. However, the first limiting structure 71 of this application is not limited to a limiting flange; it can also be other elements that can play a limiting role, such as a limiting shaft, a limiting flange, etc.

[0119] In its natural state, the operating lever 70 is in the second position, and the elastic element 80 can press the operating lever 70 and the air regulating lever 50 together, thus fixing the operating lever 70 and the air regulating lever 50 in place. When it is necessary to adjust the suction resistance parameter or the air intake volume, pull the operating lever 70 downward in the first direction to compress the elastic element 80, causing the operating lever 70 to separate from the air regulating lever 50, and the operating lever 70 to switch from the second position to the first position. Then, rotate the operating lever 70 circumferentially, driving the sealing element 60 to rotate synchronously, until the desired second vent 521 with the corresponding aperture is selected. After the second vent 521 is selected, push the operating lever 70 upward in the first direction to return the operating lever 70 from the first position to the second position, the elastic element 80 resets, and the operating lever 70 and the air regulating lever 50 are fixedly connected again.

[0120] Preferably, the degree to which the elastic element 80 can be compressed in the first direction should be less than the degree to which the first limiting part and the second limiting part can separate, so as to ensure that in any first position, the first limiting part and the second limiting part are not completely separated in the first direction, and the circumferential movement of the operating lever 70 can also drive the elastic element 80 to rotate synchronously in the circumferential direction to select the second vent 521 of the corresponding diameter. In other embodiments of this application, the elastic element can also be a bellows or the like. This application does not limit the material of the elastic element, as long as it can facilitate the switching of the operating lever between the first position and the second position.

[0121] Specifically, in this embodiment, the elastic element 80 is a spring and is sleeved on the outer surface of the operating rod 70. In some other possible embodiments, the spring may not be sleeved on the outer surface of the operating rod, but rather multiple springs may be arranged circumferentially between the operating rod and the housing of the aerosol generating device. This application does not limit the number or position of the elastic elements, as long as the operating rod can be freely switched in position.

[0122] In some embodiments of this application, referring to Figures 6 and 7, the air regulating rod 50 is provided with a second limiting structure 51. In a second position, the first limiting structure 71 and the second limiting structure 51 are in a concave-convex fit to achieve synchronous circumferential rotation. Exemplarily, the second limiting structure 51 can be a limiting flange provided on the air regulating rod 50. However, the second limiting structure 51 of this application is not limited to a limiting flange; it can also be other elements capable of limiting, such as a limiting shaft, a limiting flange, etc.

[0123] Furthermore, along the first direction, one of the first limiting structure 71 and the second limiting structure 51 is provided with a limiting protrusion 711, and the other is provided with a limiting groove 511 that cooperates with the limiting protrusion 711.

[0124] Specifically, in this embodiment, the first limiting structure 71 is provided with a limiting protrusion 711, and the second limiting structure 51 is provided with a limiting groove 511 that cooperates with the limiting protrusion 711. In the second position, the operation rod 70 can rotate circumferentially to drive the air regulating rod 50 to rotate synchronously. When it is necessary to adjust the suction resistance parameter to be tested, the operation rod 70 moves downward in the first direction, the limiting protrusion 711 and the limiting groove 511 separate in the first direction, and the operation rod 70 smoothly switches from the second position to the first position, so that the operation rod 70 rotates circumferentially until the selected second vent 521 of the corresponding diameter is selected. Then, the operation rod 70 is pushed upward in the first direction, the limiting protrusion 711 and the limiting groove 511 are connected in the first direction to achieve a concave-convex fit, and the operation rod 70 returns to the second position, realizing the fixed connection between the operation rod 70 and the air regulating rod 50.

[0125] Furthermore, in this embodiment, the adjusting rod 40 is also provided with a third limiting structure 42, which is used to abut against the external component installed on the length adapter along the first direction to limit the distance the adjusting rod 40 can move along the first direction. During the upward movement of the adjusting rod 40 along the first direction, when the third limiting structure 42 abuts against the housing support 30 in the aerosol generating device 130, the adjusting rod 40 reaches its limit of upward movement in the first direction. Exemplarily, the third limiting structure 42 can be a limiting flange provided on the adjusting rod 40. However, the third limiting structure 42 in this application is not limited to a limiting flange; it can also be other elements that can play a limiting role, such as a limit switch, a limit flange, etc.

[0126] Furthermore, the receiving part is a heating element 90, used to heat the aerosol generating article 100 placed in the heating element 90.

[0127] When using the aerosol generating device 130 of this application to adjust the length of the aerosol generating article 100 contained in the heating element 90, the operating lever 70 is in the second position. At this time, simply rotating the operating lever 70, with the cooperation of the limiting protrusion 711 of the first limiting structure 71 and the limiting groove 511 of the second limiting structure 51, the operating lever 70 can drive the gas adjusting lever 50 to move synchronously in the circumferential direction. Since the gas adjusting lever 50 is threadedly engaged with the length adjusting lever 40, the length adjusting lever 40 also has a tendency to move in the circumferential direction. However, under the restriction of the rib 11 on the heating element support 10, the circumferential movement tendency of the length adjusting lever 40 is transformed into linear movement in the first direction. In this way, the length of the aerosol generating article 100 heated in the heating element 90 is adjusted to adapt to aerosol generating articles 100 with different appearance design parameters.

[0128] The aerosol generating device 130 of this application can also be used to adjust the air intake or suction resistance parameters when heating the aerosol generating product 100. In its natural state, the operating lever 70 is in the second position. When adjusting the air volume, the operating lever 70 must first be switched from the second position to the first position. The operating lever 70 must be pulled downwards in the first direction to compress the spring, separating the operating lever 70 from the air regulating lever 50. Specifically, the first limiting structure 71 is first completely separated from the air regulating lever operating flange 51, then the operating lever 70 is moved circumferentially, causing the sealing element 60 to move synchronously. After selecting the second vent 521 corresponding to the desired air volume, the operating lever 70 is pushed in in the first direction, the first limiting structure 71 and the air regulating lever operating flange 51 are restored to their original engagement, the spring returns to its original position, and the operating lever 70 and the air regulating lever 50 are fixedly connected again, completing the adjustment of the air intake volume. When measuring the suction resistance parameter, the external airflow flows sequentially through the third vent 72, the fourth vent 61, the second vent 521 and the first vent 44, and enters the aerosol generating product 100.

[0129] On the other hand, refer to Figure 1 , Figure 2 As shown in Figure 6, some embodiments of this application also disclose an aerosol generating device 130, including a receiving part for accommodating an aerosol generating article 100 and an air volume regulating device for the aerosol generating device 130, wherein the air volume regulating device includes a first vent 44 and an operating part 110 that can communicate with the receiving part accommodating the aerosol generating article 100.

[0130] The operation unit 110 includes: a plurality of second vent holes 521 with different apertures and an aperture adjustment unit 120. The aperture adjustment unit 120 is used to select a second vent hole 521 with a corresponding aperture that communicates with the first vent hole 44. The first vent hole 44 and the second vent hole 521 form at least a part of an airflow channel communicating with the outside.

[0131] In some embodiments of this application, reference is made to Figure 1 , Figure 2 Figures 5 to 7 show that the gas volume regulating device includes an adjusting rod 50 and an operating rod 70. The adjusting rod 50 extends along a first direction, which is consistent with the extension direction of the aerosol generating product 100. The adjusting rod 50 has multiple second vent holes 521 of different diameters spaced circumferentially around the first direction. The operating rod 70 is sleeved on the outer surface of the adjusting rod 50 and has a third vent hole 72 and a sealing element 60, allowing switching between a first position and a second position.

[0132] In the first position, the operating lever 70 can rotate circumferentially relative to the air regulating lever 50 so that the third vent 72 communicates with the second vent 521 of the corresponding diameter. The sealing member 60 rotates synchronously with the operating lever 70 circumferentially, and the first vent 44, the second vent 521, and the third vent 72 form at least a part of the airflow channel communicating with the outside.

[0133] In the second position, the operating lever 70 is fixedly connected to the air regulating lever 50, and the sealing element 60 seals the second vent 521 of multiple second vents 521 with different diameters that is not connected to the third vent 72.

[0134] In this embodiment, the air volume regulating device further includes at least a portion of an adjusting rod 40 disposed within the adjusting rod 50, and a first vent 44 disposed within the adjusting rod 40 and penetrating the main body of the adjusting rod 40. In another embodiment of this application (not shown), the air volume regulating device does not include the adjusting rod, such that the first vent is disposed within the adjusting rod, forming at least a portion of an airflow channel communicating with the outside with the second vent and the third vent.

[0135] In some embodiments of this application, reference is made to Figure 1 and Figure 2 The operating lever 70 can be separated from the air regulating lever 50 in the first direction to switch from the second position to the first position.

[0136] In some embodiments of this application, reference is made to Figure 2 As shown in Figures 5 to 7, the air regulating rod 50 is provided with a flow component 52, which has multiple second vent holes 521 of different diameters. The flow component 52 and the inner wall of the air regulating rod 50 form a sealing element receiving portion. The sealing element 60 includes a fourth vent hole 61 and a first limiting portion, with at least a portion of the sealing element 60 located within the sealing element receiving portion. The operating rod 70 is provided with a second limiting portion, which cooperates with the first limiting portion to allow the sealing element 60 and the operating rod 70 to rotate synchronously in the circumferential direction. The third vent hole 72 communicates with the fourth vent hole 61. The end of the sealing element 60 is fitted against the flow component 52 to seal the second vent hole 521 of the multiple second vent holes 521 of different diameters that is not connected to the third vent hole 72.

[0137] In this embodiment, the operating part 110 has five second vent holes 521 of different diameters, arranged circumferentially on the flow member 52, with diameters of 0.5cm, 0.8cm, 1.1cm, 1.4cm, and 1.7cm, respectively. This application does not limit the number or size of the second vent holes and can set them according to actual needs. In this application, when adjusting the suction resistance parameter, i.e., the air intake volume, for example, if the initially selected second vent hole 521 has a diameter of 1.1cm, and a larger suction resistance parameter needs to be tested, the air intake volume needs to be reduced, and a second vent hole 521 with a smaller diameter needs to be selected. For example, in this embodiment, a second vent hole 521 with a diameter of 0.5cm or 0.8cm can be selected.

[0138] In some embodiments of this application, referring to Figures 6 and 7, the first limiting portion and the second limiting portion are in a concave-convex fit. In the first position and the second position, the sealing member 60 is located within the sealing member receiving portion. In the first position, the second limiting portion can be separated from the first limiting portion along a first direction.

[0139] Specifically, in this embodiment, the seal 60 is made of silicone. In other embodiments of this application, the seal may also be made of rubber, PVC, etc., as long as it can seal the second vent hole on the flow component.

[0140] In some embodiments of this application, reference is made to Figure 2 Figures 6 and 7 show that the operating lever 70 is provided with a first limiting structure 71. The gas volume regulating device also includes an elastic element 80. Along the first direction, one end of the elastic element 80 abuts against one end of the first limiting structure 71, and the other end abuts against the external component on which the gas volume regulating device is installed. The elastic element 80 can be compressed to separate the operating lever 70 from the gas regulating rod 50 along the first direction. Here, the external component on which the gas volume regulating device is installed also refers to the housing of the aerosol generating device 130. Specifically, in this embodiment, the elastic element 80 is a spring and is sleeved on the outer surface of the operating lever 70. In the second position, since the spring can press the operating lever 70 and the gas regulating rod 50 together, it can prevent movement along the first direction when the operating lever 70 moves circumferentially. The degree to which the elastic element 80 can be compressed in the first direction should be less than the degree to which the first limiting part and the second limiting part can separate, to ensure that when switching from the second position to the first position, the operating lever 70 can drive the elastic element 80 to rotate synchronously along the circumferential direction. In other embodiments of this application, the elastic element may also be a bellows or the like, and multiple elastic elements may be arranged circumferentially along the operating lever. This application does not limit the location, number, or material of the elastic elements, as long as it facilitates switching between the first and second positions.

[0141] Using the aerosol generating device 130 of this application, the air intake volume when heating the aerosol generating product 100 can be easily adjusted. In its natural state, the operating lever 70 is in the second position. When adjusting the air volume, the operating lever 70 must first be switched from the second position to the first position. Specifically, the operating lever 70 must be separated from the adjusting lever 50 along the first direction, so that the first limiting structure 71 is completely separated from the adjusting lever 50. Then, the operating lever 70 is moved circumferentially. At this time, the adjusting lever 50 does not move, and the operating lever 70 can drive the sealing element 60 to move synchronously. After selecting the second vent 521 corresponding to the desired air volume, the operating lever 70 is pushed in along the first direction, the spring returns to its original position, and the operating lever 70 and the adjusting lever 50 are fixedly connected again, completing the adjustment of the air intake volume.

[0142] Although this application has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the application in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the application to these descriptions. Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of this application.
