[0069] To facilitate understanding of this application, a more detailed description of this application will be provided below in conjunction with the accompanying drawings and specific embodiments.

[0070] One embodiment of this application provides an aerosol generating device for receiving aerosol generating articles to generate aerosols.

[0071] In an optional embodiment, the aerosol-generating article preferably uses a tobacco-containing material from which volatile compounds are released from the matrix upon heating; or it may be a non-tobacco material suitable for electric heating and smoking after heating. The aerosol-generating article preferably uses a solid matrix, which may include one or more of the following: vanilla leaves, tobacco leaves, homogenized tobacco, expanded tobacco, powder, granules, fragments, strips, or sheets; or the solid matrix may contain additional tobacco or non-tobacco volatile aroma compounds to be released when the matrix is ​​heated.

[0072] In an optional implementation, the aerosol-generating article includes a cigarette stick in the shape of an elongated column.

[0073] See further Figures 1 to 2 As shown, in one embodiment, the aerosol generating device 100 is configured to be generally square in shape.

[0074] exist Figure 1 In the embodiment shown, the aerosol generating device 100 includes:

[0075] The proximal end 110 and the distal end 120 are opposite each other along the length direction; according to the needs of normal use, the proximal end 110 is configured as the end at which the user inhales the aerosol, and in use the aerosol generating article is at least partially received into the aerosol generating device 100 through the proximal end 110 and heated to generate an aerosol.

[0076] Further according to Figure 1 and Figure 2 The aerosol generating device 100 is defined as follows:

[0077] The first space 1100 extends from the proximal end 110 to the distal end 120; and the first space 1100 is located on one side of the aerosol generating device 100 along the width direction; in use, the first space 1100 is a space for accommodating and assembling the battery cell 11 for power supply.

[0078] The second space 1200 is located near the far end 120 and is opposite or adjacent to a portion of the first space 1100 along the width direction; in use, the second space 1200 is a space for accommodating and assembling circuit boards such as PCBs.

[0079] The third space 1300 is located primarily near the proximal end 110 and is opposite to the second space 1200 along its length and opposite or adjacent to the portion of the first space 1100 near the proximal end 110 along its width. In use, the third space 1300, at least partially defined as a heating space, receives and heats at least a portion of the aerosol-generating article to generate an aerosol for suction.

[0080] In a preferred embodiment, the first space 1100, the second space 1200, and the third space 1300 are substantially airtight with each other to prevent the flow of hot air or aerosols in front of them.

[0081] See further Figure 3 As shown, Figure 3 A schematic diagram of an aerosol generation system consisting of an aerosol generating device 100 and a product box 200 is shown. According to... Figure 3 As shown, the product box 200, such as a cigarette box, is usually constructed in a square shape; the product box 200 usually has an openable flip cover 300, by which the aerosol contained inside the product box 200 can be taken out to generate a product such as a cigarette.

[0082] Further according to Figure 3 As shown, the aerosol generating device 100 has a similar shape and size to the product box 200, such as a cigarette box, which is advantageous for placement in conjunction with the product box 200.

[0083] Further according to Figure 3 As shown, the outer surface of the aerosol generating device 100 has several planes, with the largest area being the planar side surfaces located on both sides in the thickness direction; similarly, the product box 200, such as a cigarette box, also has planar side surfaces located on both sides in the thickness direction, which are the largest areas. When the side surfaces of the aerosol generating device 100 along the thickness direction and the side surfaces of the product box 200 along the thickness direction are combined, their contact area is defined by the smaller of the two planes.

[0084] Of course, in some implementations, the area or shape of the largest plane on the outer surface of the aerosol generating device 100 is basically the same as or close to the area or shape of the largest plane on the outer surface of the product box 200. Or in some implementations, the area or shape of the surface of the aerosol generating device 100 along the thickness direction is basically the same as or close to the area or shape of the surface of the product box 200 along the thickness direction.

[0085] At the same time, according to Figure 3 As shown, the side surface of the aerosol generating device 100 that contacts or is coupled with the product box 200 is square; and any other side surface of the aerosol generating device 100 adjacent to the side surface in contact with the product box 200 is also square; for example Figure 3 The side surfaces of the mist generating device 100 are square in both the length and width directions.

[0086] At the same time, according to Figure 3As shown, when the aerosol generating device 100 and the product box 200 are combined along the thickness direction, the side surface of the aerosol generating device 100 facing away from the product box 200 along the thickness direction, and the side surface of the product box 200 facing away from the aerosol generating device 100, are exposed. In use, the user can simultaneously hold the aerosol generating device 100 and the product box 200 together by pinching their fingers; this is advantageous for easy portability.

[0087] according to Figure 3 As shown, the aerosol generating device 100 and the product box 200 have basically similar shapes and sizes. In practice, the product box 200 has a length of approximately 70 to 80 mm, a width of approximately 40 to 50 mm, and a thickness of approximately 10 to 20 mm.

[0088] according to Figure 3 As shown, the corresponding aerosol generating device 100 can have a length L of approximately 70-80 mm, a width W of approximately 40-50 mm, and a thickness H of approximately 9.5-20 mm. In this implementation, the two surfaces of the aerosol generating device 100 along the thickness direction are the planes with the largest area, approximately 2800 mm². 2 ~4000mm 2 .

[0089] In some alternative embodiments, the extension length / thickness of the first space 1100 is substantially close to the length L / thickness H of the aerosol generating device 100. The width of the first space 1100 is between 1 / 3 and 2 / 3 of the width W of the aerosol generating device 100; more preferably, the width of the first space 1100 is substantially close to 1 / 2 of the width W of the aerosol generating device 100. In some embodiments, the first space 1100 also has a length of approximately 60 to 65 mm, a width of approximately 15 to 25 mm, and a thickness of approximately 5 to 10 mm.

[0090] Accordingly, according to Figure 2 As shown, the battery cell 11 housed or assembled in the first space 1100 is configured to be substantially square in shape. Accordingly, in some embodiments, the volume or shape of the battery cell 11 is substantially the same as or close to that of the first space 1100. In some embodiments, the battery cell 11 has a length of approximately 60 to 65 mm, a width of approximately 15 to 25 mm, and a thickness of approximately 5 to 10 mm.

[0091] Furthermore, in some optional embodiments, the second space 1200 has a length dimension of approximately 35 to 50 mm, a width dimension of 15 to 25 mm, and a thickness dimension of approximately 5 to 10 mm.

[0092] Furthermore, in some optional embodiments, the third space 1300 has a length of approximately 25 mm to 40 mm, a width of 15 mm to 25 mm, and a thickness of approximately 5 mm to 10 mm.

[0093] In some other embodiments, the width of the second space 1200 and / or the third space 1300 is between 1 / 3 and 2 / 3 of the width W of the aerosol generating device 100; more preferably, the width of the second space 1200 and / or the third space 1300 is substantially close to 1 / 2 of the width W of the aerosol generating device 100.

[0094] The thickness of the second space 1200 and / or the third space 1300 is basically close to the thickness H of the aerosol generating device 100.

[0095] In some embodiments, the extension length of the second space 1200 is greater than the extension length of the third space 1300. In some other embodiments, the extension length of the second space 1200 is between 1 / 2 and 2 / 3 of the length of the aerosol generating device 100. In some other embodiments, the extension length of the third space 1300 is between 1 / 3 and 1 / 2 of the length of the aerosol generating device 100.

[0096] Further according to Figure 4 As shown, in another optional embodiment, the aerosol generating device 100 is provided with a wireless charging coil 1400 located near at least one side in the thickness direction; the wireless charging coil 1400 can be used to couple with an external wireless charging device, thereby receiving the electromagnetic energy of the wireless charging device to generate a charging current and thus charging the battery cell 11.

[0097] Further according to Figure 4 As shown, the wireless charging coil 1400 used for wirelessly charging the battery cell 11 is a planar helical coil. In some embodiments, the wireless charging coil 1400 is a generally square planar helical coil, such as... Figure 4 As shown. Alternatively, in some implementations, the wireless charging coil 1400 may also be configured as a circular planar helical coil.

[0098] In some alternative embodiments, the wireless charging coil 1400 is made of a conductor material with a circular or rectangular cross-section; such conductor materials include, for example, common copper wire, nickel wire, etc. Alternatively, in yet another alternative embodiment, the planar spiral coil of the wireless charging coil 1400 is in the form of a deposited, printed, or etched coating, track, or line; for example, the wireless charging coil 1400 is in the form of a planar spiral coil formed by printing, depositing, or otherwise creating a coating or line on a substrate using conductive material. Alternatively, in yet another alternative embodiment, the planar spiral coil of the wireless charging coil 1400 is in the form of a planar spiral coil formed by etching or cutting a sheet of conductive metal substrate.

[0099] further Figures 5 to 7 A schematic diagram of an aerosol generating device 100 according to a specific embodiment is shown. In this embodiment, the aerosol generating device 100 includes:

[0100] The main housing 10 mainly serves as the outer shell component of the aerosol generating device 100, and further defines the first space 1100, the second space 1200 and the third space 1300 inside it; therefore, in practice, the main housing 10 generally has the shape and size requirements of the aerosol generating device 100 described above.

[0101] The cover 20 is located at the proximal end 110 of the main housing 10 and / or the aerosol generating device 100, and is configured in practice to be movable relative to the main housing 10; of course, according to Figure 5 and Figure 6 In the preferred embodiment shown, the movement of the door cover 20 relative to the main housing 10 is a sliding motion along the width direction of the main housing 10, such as... Figure 6 As indicated by the middle arrow R1; or in other variations, the movement of the cover 20 relative to the main housing 10 may be in the form of rotation about a certain axis.

[0102] according to Figures 5 to 7 As shown, the sliding design of the door cover 20 allows it to have an open position and a closed position. For example, in the closed position, the door cover 20... Figure 5 As shown, the cover 20 forms a barrier or seal on the third space 1300, at which time the aerosol generating device 100 is locked and unusable; the cover 20 in the open position, for example... Figure 6 and Figure 7 As shown, the third space 1300 is exposed, so that the user can receive the aerosol-generated product A into the aerosol generating device 100 for suction and clean the third space 1300.

[0103] Further according to Figures 5 to 7As shown, the main housing 10 is provided with a guide groove 11 for guiding the movement of the cover 20. Specifically, in a preferred embodiment, the guide groove 11 is provided on the side surface of the main housing 10 along its thickness direction; and the guide groove 11 is configured as an elongated groove extending along the width direction of the main housing 10. In use, the cover 20 extends at least partially into the guide groove 11, thereby cooperating with the guide groove 11 to guide the movement; and the end positions at both ends of the guide groove 11 are used to limit the movement of the cover 20.

[0104] In the embodiment shown in the figure, the guide groove 11 has a length of approximately 30 to 40 mm.

[0105] The shape or structure of the door cover 20 can be seen in Figure 8 As shown, the door cover 20 includes:

[0106] The first shielding wall 210 is basically parallel to the upper side of the main housing 10; in the closed position, it shields or closes the third space 1300 at the proximal end 110.

[0107] The second shielding wall 220 and the third shielding wall 230 extend along the length of the main housing 10, and the second shielding wall 220 and the third shielding wall 230 are connected to the first shielding wall 210 at the proximal end 110. The second shielding wall 220 and the third shielding wall 230 are respectively arranged on both sides of the thickness direction of the main housing 10; thus, in use, the second shielding wall 220 and the third shielding wall 230 respectively shield or close the third space 1300 from both sides of the thickness direction of the main housing 10.

[0108] Furthermore, the second shielding wall 220 is provided with a first hook 221 at the end opposite to the first shielding wall 210, and / or the third shielding wall 230 is provided with a second hook 231 at the end opposite to the first shielding wall 210; in use, the first hook 221 and / or the second hook 231 extend at least partially into the guide groove 11, providing guidance while maintaining connection with the main housing 10, so as to prevent the first hook 221 and / or the second hook 231 from dislodging from the guide groove 11 and causing the door cover 20 to fall off the main housing 10.

[0109] exist Figure 8 In the preferred embodiment shown, the first shielding wall 210 and / or the second shielding wall 220 and / or the third shielding wall 230 are rectangular in shape. In a more preferred embodiment, the first shielding wall 210 has a length of approximately 15 to 25 mm and a width of approximately 5 to 10 mm. The second shielding wall 220 and / or the third shielding wall 230 have a length of approximately 28 to 40 mm and a width of approximately 15 to 25 mm.

[0110] In a more preferred embodiment, the cover 20 is made of a material with high thermal conductivity, such as metal, which is beneficial for promoting heat dissipation of the heating components within the third space 1300 and for evenly transferring heat to other parts.

[0111] See further Figure 6 and Figure 7 As shown, the aerosol generating device 100 includes:

[0112] The receiving port 41 is located at the proximal end 110, through which the aerosol-generated article A can be at least partially received into the aerosol generating device 100.

[0113] exist Figure 10 In the preferred embodiment shown, the receiving hole 41 is defined by the extractor 40. Alternatively, in other variations, when the aerosol generating device 100 does not have the extractor 40, the receiving hole 41 may also be defined by the main housing 10 or the support 30, etc.

[0114] See also Figure 10 As shown, the aerosol generating device 100 includes:

[0115] The receiving cavity 430 is in which at least a portion of the aerosol-generated article A is removably received; the receiving cavity 430 is in communication with the receiving port 41.

[0116] exist Figure 10 In the preferred embodiment shown, the receiving cavity 430 is also defined by the extractor 40. Alternatively, in other variations, when the aerosol generating device 100 does not have the extractor 40, the receiving cavity 430 may also be defined by the main housing 10 or the support 30, etc.

[0117] Further according to Figure 9 and Figure 10 As shown, the aerosol generating device 100 includes:

[0118] Heater 50 is configured in the shape of a pin, needle, or plate, etc., for example Figure 9 The needle-shaped heater 50 is used to heat the aerosol generating article A when it is received within the aerosol generating apparatus 100. In some alternative embodiments, the pin- or needle-shaped heater 50 has a length of approximately 12–19 mm and an outer diameter of approximately 2–5 mm. In still other alternative embodiments, the plate-shaped heater 50 may have a length of approximately 12–19 mm, a width of approximately 3–6 mm, and a thickness of approximately 0.4–1 mm. Accordingly, according to Figure 10 As shown, the heater 50 extends at least partially within the receiving cavity 430, which is advantageous for heating when inserted into the aerosol-generating article A.

[0119] In other variations, the heater 50 may also be configured in a cylindrical shape; in use, its internal space defines a receiving cavity 430 for receiving aerosol-generating article A and generating aerosol by heating the outer periphery of the aerosol-generating article A.

[0120] In some alternative implementations, heater 50 is a resistance heater; or in some implementations, heater 50 is a sensor that is heated by being penetrated by a magnetic field.

[0121] Further according to Figure 9 and Figure 10 As shown, the aerosol generating device 100 includes:

[0122] The support 30, in practice, supports the extractor 40. The support 30 is also configured to surround or shield the heater 50 for protection. Specifically:

[0123] The bracket 30 is detachably installed within the third space 1300, providing support or holding the extractor 40 when it is connected to the aerosol generating device 100. Furthermore, since the bracket 30 at least partially surrounds or covers the heater 50, it at least prevents the heater 50 from being completely exposed within the third space 1300, thus helping to prevent user contact or touching.

[0124] In a preferred embodiment, the support 30 has a generally square shape. Specifically, the support 30 has a length of approximately 25 mm to 40 mm, a width of 15 to 25 mm, and a thickness of approximately 5 to 10 mm.

[0125] See further Figure 9 and Figure 10 As shown, the extractor 40 includes:

[0126] A cylindrical receiving portion 420, the internal space of which is configured as a receiving cavity 430 for receiving the aerosol-generated article A;

[0127] The operating part 410 is used by the user to move or remove the extractor 40 to extract the aerosol product A by operating the operating part 410 with their fingers or the like. When the extractor 40 is installed in the aerosol generating device 100, it is connected to the main housing 10 through the operating part 410, thereby stably holding the extractor 40 on the aerosol generating device 100. Of course, in some embodiments, the operating part 410 can be directly or indirectly connected to the main housing 10. Or in... Figure 9 and Figure 10In a preferred embodiment, the operating part 410 is fixed and held within the aerosol generating device 100 by abutting against and connecting to the upper end of the bracket 30.

[0128] In a further preferred embodiment, the extractor 40 can be moved or removed relative to the main housing 10, thus presenting an operating position and an extraction position with relative positions. Specifically:

[0129] Figure 11 A schematic diagram of an embodiment with the extractor 40 in an operating position is shown. In this position, the aerosol-generating article A is received within a receiving portion 420 and supported by a support wall 421 of the receiving portion 420. A heater 50 extends at least partially through the support wall 421 into a receiving cavity 430 defined by the receiving portion 420, thereby heating the aerosol-generating article A. The operating position is essentially formed by the insertion of the heater 50 into the aerosol-generating article A. In this operating position, the extractor 40 remains connected to the main housing 10.

[0130] Figure 12 A schematic diagram of an embodiment with the extractor 40 in an extraction position is shown. In the extraction position, the extractor 40 is operated by the operating part 410 to move or remove the extractor 40 along its length relative to the main housing 10, thereby separating the aerosol-generated article A from the heater 50 under the support of the support wall 421 and removing it. This extraction position is formed by the separation of the aerosol-generated article A from the heater 50.

[0131] In one alternative embodiment, the extractor 40 is also directly or indirectly connected to the main housing 10 in the extraction position, which is advantageous in preventing the extractor 40 from detaching from the aerosol generating device 100. Alternatively, in yet another alternative embodiment, the extractor 40 is not directly or indirectly connected to the main housing 10 in the extraction position, in which case the extractor 40 is detached from the main housing 10 and / or the support 30 in the extraction position, which is advantageous in facilitating direct removal or detachment from the aerosol generating device 100.

[0132] In one alternative embodiment, the aerosol-generated article A has a length of approximately 40 to 80 mm and an outer diameter of approximately 4 to 8 mm.

[0133] In yet another preferred embodiment, the receiving portion 420 of the extractor 40 has a length of approximately 15 to 40 mm; and the receiving portion 420 has a corresponding inner diameter of approximately 4 to 8 mm.

[0134] See further Figure 13 As shown, the extractor 40 also includes:

[0135] The first hole 422, located on the supporting wall 421, has an inner diameter that is basically adapted to and slightly larger than that of the heater 50, allowing the heater 50 to pass through the first hole 422 and be inserted into the receiving portion 420; when adapted to a pin or needle-shaped heater 50, for example Figure 13 As shown, the first hole 422 is circular and has an inner diameter of approximately 3 to 6 mm.

[0136] The second hole 423, located on the supporting wall 421, is used for external air to enter the aerosol-generating product A through the second hole 423 during the suction process, such as... Figure 13 As indicated by the middle arrow R2. In practice, the second hole 423 has an inner diameter of approximately 1–2 mm. Furthermore, there can be several second holes 423 arranged around the first hole 422.

[0137] Further according to Figure 9 and Figure 10 As shown, the structure of the support 30 includes:

[0138] The left side wall 310 and the right side wall 320 are opposite to each other in the width direction; during assembly, the left side wall 310 is the side wall adjacent to the first space 1100 and is detachably connected to the main housing 10 by means of snap-fit ​​or the like; the right side wall 320 is at least partially exposed outside the aerosol generating device 100 after assembly and at least partially defines the outer surface of the aerosol generating device 100 in the width direction.

[0139] The lower end wall 350 adjacent to the second space 1200 along the length direction has a third hole 33 formed on it. During assembly, the heater 50 passes through the third hole 33 from below along the length direction into the bracket 30.

[0140] A window 32 is provided on a front sidewall 330 and a rear sidewall 340 that are opposite each other along the thickness direction, near the lower end wall 350. In an optional embodiment, the front sidewall 330 and the rear sidewall 340 are not connected to or in contact with the lower end wall 350. In another embodiment, the window 32 is defined by the spacing between the front sidewall 330 and / or the rear sidewall 340 and the lower end wall 350.

[0141] In practice, window 32 is directly connected to the outside air, so the second hole 423 of the extractor 40 can be connected to the outside air through window 32; therefore, during the suction process, the outside air directly enters the second hole 423 through window 32, and then enters the receiving cavity 430, where it is sucked up by the user along with the aerosol generated by aerosol generating product A. Figure 10 As indicated by the middle arrow R2.

[0142] Further according to Figure 9 , Figure 10 and Figure 14As shown, the free front end of the heater 50 extends into the bracket 30; the end of the heater 50 opposite to the free front end is fixed within the main housing 10. Further according to the embodiment shown in the figure, the end of the heater 50 opposite to the free front end is surrounded and fixed by the fixing seat 52.

[0143] The heater 50 has an exposed portion 51 that protrudes from the window 32; this exposed portion 51 is approximately 2 to 5 mm in length. The exposed portion 51 of the heater 50 is visible through the window 32. Of course, after assembly, the exposed portion 51 is defined by the size or position of the window 32. Specifically, in this embodiment, the mounting base 52 is covered and obscured by the lower end wall 350 of the bracket 30, so the exposed portion 51 of the heater 50 is completely defined by the bracket 30; specifically, it is defined by the portion of the heater 50 along its length located between the lower end wall 350 of the front side wall 330 and / or the rear side wall 340.

[0144] Of course, this exposed portion 51 is located near the end of the mounting base 52 and / or the heater 50. From Figure 14 It can be seen that the distance d4 between the exposed portion 51 of the heater 50 and the free front end is approximately 12 mm. This exposed portion 51 is far from the free front end, making it difficult for cleaning instruments to directly clean the exposed portion 51 through the receiving port 41 of the extractor 40. In typical implementations, the distance d4 between the exposed portion 51 of the heater 50 and the free front end is greater than 8 mm.

[0145] In another embodiment, window 32 has a suitable area, allowing for the cleaning of the exposed portion 51 of heater 50 by inserting cleaning tools into window 32 during use. In some embodiments, cleaning tools include small brushes, wire strips, scrapers, etc.

[0146] In some preferred embodiments, the window 32 must have a suitable area to provide the necessary size for the cleaning appliance to be inserted, while also preventing the user's fingers from being burned by the heater 50.

[0147] In a preferred embodiment, window 32 has a diameter greater than 10 mm. 2 The area and less than 100mm 2 The area. In a more preferred embodiment, window 32 has an area greater than 30mm. 2 The area is less than 80mm 2 The area.

[0148] exist Figure 9 and Figure 14In the preferred embodiment shown, the window 32 is substantially square in shape. For example, the window 32 is an elongated strip extending in the width direction of the bracket 30. In a more preferred embodiment, the length dimension d1 of the window 32 extending in the width direction of the bracket 30 is approximately 10 to 20 mm; and the width dimension d2 of the window 32 extending in the length direction of the bracket 30 is approximately 3 to 6 mm.

[0149] exist Figure 14 In one specific implementation shown, the length dimension d1 of window 32 is 17mm; and the width dimension d2 of window 32 is approximately 4.2mm.

[0150] In another alternative embodiment, at least one of the length dimension d1 and the width dimension d2 of the window 32 must not exceed 10 mm, which is advantageous for preventing the user's fingers from being inserted. In a more preferred embodiment, at least one of the length dimension d1 and the width dimension d2 of the window 32 must not exceed 6 mm.

[0151] Correspondingly, the length of the exposed portion 51 of the heater 50 is approximately 3 to 6 mm. In a preferred embodiment, the length of the heater 50 extending into the receiving portion 420 of the extractor 40 is approximately 10 to 18 mm. In a preferred embodiment, the length of the exposed portion 51 of the heater 50 does not exceed one-third of the total length of the heater 50.

[0152] See further Figure 9 and Figure 10 As shown, to facilitate the guidance of the extractor 40 during assembly, movement, or removal from the support 30, the support 30 also has a first inner wall 360 and a second inner wall 370. As shown in the figure, the first inner wall 360 and the second inner wall 370 are configured in an arcuate shape, and the first inner wall 360 and the second inner wall 370 are opposite in orientation. The first inner wall 360 and the second inner wall 370 are arcuate shapes that curve outwards in the width direction, thereby defining a guide receiving space 31 between them. The shape of this receiving space 31 is substantially the same as that of the receiving portion 420 of the extractor 40, and the size and volume of the receiving space 31 are slightly larger than the volume of the receiving portion 420. Thus, the first inner wall 360 and the second inner wall 370 provide guidance when the extractor 40 is stably assembled onto the support 30, and during movement or removal.

[0153] Alternatively, in another variation, when the aerosol generating device 100 does not have an extractor 40 component, the receiving space 31 between the first inner wall 360 and the second inner wall 370 is configured as a receiving cavity 430 for receiving the aerosol-generated article A.

[0154] At the same time, according to Figure 5 and Figure 6As shown, when the door cover 20 is in the closed position, it obscures or closes the window 32; and when the door cover 20 is in the open position, it opens or exposes the window 32a.

[0155] exist Figure 9 and Figure 10 In the preferred embodiment shown, there is a gap between the first inner wall 360 and the left side wall 310 of the support 30, thereby forming a first heat insulation cavity 34 between them; there is a gap between the second inner wall 70 and the right side wall 320 of the support 30, thereby forming a second heat insulation cavity 35 between them.

[0156] In the embodiment shown in the figure, the first insulating cavity 34 and / or the second insulating cavity 35 are empty and open, thus communicating with the outside air, thereby forming insulation through the low thermal conductivity of the air; the first insulating cavity 34 prevents the heat of the heater 50 from being transferred radially outward to the cell 11 of the first space 1100; and / or the second insulating cavity 35 prevents the heat of the heater 50 from being transferred radially outward to the right side wall 320.

[0157] In some variations, the first insulating cavity 34 and / or the second insulating cavity 35 are closed cavities, which allows the internal pressure to be configured to be lower than the external pressure, i.e., the first insulating cavity 34 and / or the second insulating cavity 35 have a vacuum degree; this is advantageous for preventing heat transfer.

[0158] Alternatively, in some variations, the first insulating cavity 34 and / or the second insulating cavity 35 may be filled with insulating materials such as aerogel, porous polymer, porous polyurethane, foam, etc., which is beneficial for preventing heat transfer.

[0159] See further Figure 9 and Figure 10 As shown, the receiving portion 420 of the extractor 40 is also at least partially exposed to the window 32.

[0160] Further in Figure 10 In the preferred embodiment shown, a circuit board 12 for controlling the operation of the aerosol generating device 100 is installed in the second space 1200 of the aerosol generating device 100; and a charging interface 13 located at the remote end 120 is connected to the circuit board 12 during use, and then connected to an external power supply device to charge the battery cell 11.

[0161] For the above-mentioned aerosol generating device 100, cleaning the debris or aerosol condensate that falls off the aerosol-generated product A may include:

[0162] Without removing the extractor 40, the inner wall of the receiving part 420 and part of the surface of the heater 50 can be cleaned by inserting a brush or other tool through the receiving hole 41.

[0163] After removing the extractor 40, you can continue to clean the inner wall of the receiving space 31 by reaching in with a brush or other tools; and clean the exposed part 51 of the heater 50 by reaching in through the window 32.

[0164] Further, remove the bracket 30 from the main housing 10, such as... Figure 9 As shown, the heater 50 is substantially completely exposed, allowing for deep and thorough cleaning of its surface using cleaning tools.

[0165] further Figures 15 to 18 A schematic diagram of another embodiment of the aerosol generating device 100 is shown; in this embodiment, the aerosol generating device 100 includes:

[0166] main housing 10a;

[0167] The door cover 20a is positioned at the proximal end 110a of the main housing 10a and can move relative to the main housing 10a between an open position and a closed position; for example, by moving or rotating along the width direction of the main housing 10a.

[0168] See also Figure 18 As shown, the aerosol generating device 100 also includes a limiting protrusion 17a located between the main housing 10a and the cover 20a; in assembly, the limiting protrusion 17a is located at the proximal end 110a of the main housing 10a and is at least partially protruding relative to the main housing 10a. When the cover 20a moves relative to the main housing 10a in the width direction, the limiting protrusion 17a provides a limit in the open and closed positions of the cover 20a. Of course, in a more preferred embodiment, the cover 20a covers or hides the limiting protrusion 17a at any position of movement. The limiting protrusion 17a is not exposed on the surface of the aerosol generating device 100 at any position of movement of the cover 20a.

[0169] Furthermore, the aerosol generating device 100 also includes:

[0170] The support 30a has at least a window 32a defined by it from the main housing 10a; the heater 50a is at least partially exposed within the window 32a.

[0171] Extractor 40a is supported and held by bracket 30a; in use, extractor 40a is used to extract aerosol-generated product A received in aerosol generating device 100a.

[0172] Further according to Figure 16 As shown, to facilitate stable connection between the extractor 40a and the support 30a in the operating position, a locking protrusion 43a is provided on the extractor 40a; the locking protrusion 43a is used to engage the extractor 40a with the support 30a in the operating position to form a connection. Figure 16 In the preferred embodiment shown, there are several convex protrusions 43a, and they are configured to be in the form of ridges located on the outer surface of the receiving portion 420a of the extractor 40a.

[0173] In this embodiment, the extractor 40a extracts the aerosol to generate product A by directly removing it from the support 30a along its length. Figure 16 As indicated by the middle arrow R3.

[0174] See further Figure 16 As shown, the bracket 30a is provided with a first connecting hole 15a and / or a second connecting hole 16a, with the first connecting hole 15a arranged adjacent to the first space 1100. In use, connecting components such as screws / bolts / tighteners are installed in the first connecting hole 15a and / or the second connecting hole 16a to connect the bracket 30a to the main housing 10a. Specifically, the first connecting hole 15a is arranged adjacent to the proximal end 110a; the second connecting hole 16a is arranged adjacent to the second space 1200.

[0175] Further according to the preferred embodiment shown in the figure, when the extractor 40a is held on the bracket 30a, the first connection hole 15a is covered or hidden by the extractor 40a. Specifically, the first connection hole 15a is covered by the operating part 41a of the extractor 40a. And after the extractor 40a is removed, the first connection hole 15a is exposed, at which time the user can use a screwdriver or other tool to disassemble the connecting parts such as screws / bolts / tighteners located in the first connection hole 15a; thereby detaching the bracket 30a from the main housing 10a, so that the bracket 30a can be detached from the main housing 10a.

[0176] Furthermore, the second connecting hole 16a is exposed through the window 32a; or the second connecting hole 16a is visible through the window 32a; then the user can insert a screwdriver into the second connecting hole 16a through the window 32a to disassemble the connecting parts such as screws / bolts / tighteners.

[0177] Further according to Figures 15 to 17 As shown, the aerosol generating device 100 in this example also includes:

[0178] The shielding member 60a is used to shield, cover, or close the window 32a; thus, when it is not necessary to keep the window 32a open for purposes such as suction or safety protection, the shielding member 60a is used to shield, cover, or close the window 32a. When it is necessary to clean the exposed part of the heater 50a exposed to the window 32a, or when it is necessary to disassemble the screws / bolts / tighteners in the second connection hole 16a, the window 32a can be opened by moving or removing the shielding member 60a.

[0179] Further according to Figures 15 to 17In the preferred embodiment shown, the shielding member 60a is removably attached to the bracket 30a to shield, cover, or close the window 32a. When the shielding member 60a is attached to the bracket 30a, the window 32a is shielded, covered, or closed. When the shielding member 60a is removed from the bracket 30a, the window 32a is opened.

[0180] Further according to Figures 15 to 17 As shown, when the shielding member 60a is attached to the bracket 30a, the surfaces of the shielding member 60a and the bracket 30a are flatly joined.

[0181] In the preferred embodiment shown in the figure, the shielding member 60a is attached to the bracket 30a along the width direction of the main housing 10a, or removed from the bracket 30a along the width direction of the main housing 10a.

[0182] In a more preferred embodiment, the main housing 10a is also provided with a guide rail 14a extending in the width direction; a guide groove 65a is provided on the corresponding shield 60a, thereby providing guidance during the operation of the shield 60a being attached to or removed from the bracket 30a.

[0183] In this embodiment, the window 32a is open on both the front and rear sides along the thickness direction of the main housing 10a, and on the right side away from the first space 1100 in the width direction.

[0184] Further according to Figure 20 As shown, in the open dimensions of window 32a on both sides in the thickness direction, the length dimension d11 is 20 mm; and the width dimension d12 is 6 mm.

[0185] In this embodiment, the window 32a is at least partially defined by the bracket 30a. Specifically, it is defined by the space between the bracket 30a and the main housing 10a along its length.

[0186] See further Figure 16 and Figure 17 As shown, the support 30a also defines a receiving space 31a for at least part of accommodating the extractor 40a. The receiving space 31a extends along the length direction and has a shape substantially the same as the receiving portion 420a of the extractor 40a. The size and volume of the receiving space 31a are slightly larger than the volume of the receiving portion 420a. The inner wall of the receiving space 31a serves to provide guidance when the extractor 40a is stably assembled onto the support 30a and during movement or removal.

[0187] Similarly, in the above embodiment, the receiving cavity for receiving the aerosol-generated article A is defined by the receiving portion 420a of the extractor 40a. However, when the extractor 40a is not present, the accommodating space 31a can primarily be used as the receiving cavity for receiving the aerosol-generated article A.

[0188] See further Figure 16 and Figure 17 As shown, the bracket 30a has a protruding portion 34a that protrudes away from the first space 1100 in the width direction, and a recessed portion 33a is defined between the protruding portion 34a and the other portions of the bracket 30a. Of course, as shown in the figure, the protruding portion 34a is located at the proximal end 110a, so that the formed recessed portion 33a is adjacent to the window 32a.

[0189] As shown in the figure, the receiving space 31a avoids the protrusion 34a.

[0190] Correspondingly, the shielding member 60a includes a main body portion 61a extending along its length, and a first shielding arm 62a and a second shielding arm 63a extending substantially from both sides of the thickness of the main body portion 61a along its width. After assembly, the first shielding arm 62a and the second shielding arm 63a respectively cover, block, or close the window 32a from opposite sides in the thickness direction. The main body portion 61a covers, blocks, or closes the window 32a from the right side in the width direction. Furthermore, after assembly, the main body portion 61a is received and held within the recessed portion 33a; and the surface of the shielding member 60a is flush with the support 30a.

[0191] As shown in the figure, the guide groove 65a is formed on the first shielding arm 62a and / or the second shielding arm 63a.

[0192] See further Figure 18 As shown, a first magnetic element 36a is also provided on the bracket 30a; of course, in a preferred embodiment, the first magnetic element 36a is provided within the protruding portion 34a.

[0193] Accordingly, the shielding member 60a is also provided with a second magnetic member 64a, which is used to magnetically attract the first magnetic member 36a when it is attached to the bracket 30a to shield the window 32a, thereby making the shielding member 60a stably held on the bracket 60a. In a preferred embodiment, the second magnetic member 64a is housed on the main body portion 61a of the shielding member 60a.

[0194] Accordingly, the extractor 40a is provided with a third magnetic element 45a, which is used to magnetically attract the first magnetic element 36a in the operating position, thereby making the extractor 40a stably held on the support 60a.

[0195] Further, according to the preferred embodiment shown in the figure, after assembly, the magnetic poles of the first magnetic element 36a, the second magnetic element 64a, and the second magnetic element 45a are arranged in the same direction along the length. For example, in the preferred embodiment shown in the figure, the first magnetic element 36a has a first magnetic pole, such as an N pole, facing the proximal end 110a, and a second magnetic pole, such as an S pole, facing the distal end 120a. Similarly, the second magnetic element 64a also has a first magnetic pole, such as an N pole, facing the proximal end 110a, and a second magnetic pole, such as an S pole, facing the distal end 120a. Correspondingly, the third magnetic element 45a also has a first magnetic pole, such as an N pole, facing the proximal end 110a, and a second magnetic pole, such as an S pole, facing the distal end 120a.

[0196] After assembly, the first magnetic component 36a can be magnetically attracted to the second magnetic component 64a and the second magnetic component 45a located on the upper and lower sides.

[0197] See further Figure 19 and Figure 20 As shown, the receiving portion 420a of the extractor 40a has a relatively longer length. Therefore, after assembly, the receiving portion 420a of the extractor 40a completely covers the heater 50a, making the heater 50a invisible when the extractor 40a is attached to the bracket 30a. In a specific implementation, the front end of the receiving portion 420a abuts against the upper surface 521a of the mounting base 52a facing the proximal end 110a.

[0198] Furthermore, a first air inlet 46a is provided at the front end of the receiving part 420a of the extractor 40a to allow air from the window 32a to enter the extractor 40a, for allowing air to enter the receiving part 420a.

[0199] In this embodiment, the receiving portion 420a has a supporting wall 421a for providing support for the aerosol-generated article A. Further according to... Figure 18 and Figure 19 As shown, the extractor 40a also has an extension wall 424a extending from the receiving portion 420a, which abuts against the upper surface 521a of the mounting base 52a during assembly. In use, the extension wall 424a serves two purposes: firstly, it shields and covers the exposed portion 51a of the heater 50a exposed to the window 32a; secondly, and more importantly, it creates a space between the mounting base 52a and the supporting wall 421a to block or retain aerosols that seep or leak from the first hole 422a and / or the second hole 423a, which is advantageous in preventing the aerosols from being visible to the user after they have seeped or leaked from the first hole 422a and / or the second hole 423a.

[0200] Of course, after the extractor 40a is moved or removed from the support 30a to extract the aerosol to generate article A, the extension wall 424a is open to the exposed portion 51a of the heater 50a, so that the user can use cleaning tools to clean the exposed portion 51a of the heater 50a through the window 32a.

[0201] Accordingly, the first air inlet 46a is formed on the extended wall 424a.

[0202] Further in this embodiment, according to Figure 16 As shown, the exposed portion 51a of the heater 50a is defined by the bracket 30a and the mounting base 52a that secures the end of the heater 50a. Specifically, in this embodiment, the exposed portion 51a is defined by the portion of the heater 50a located between the bracket 30a and the mounting base 52a. Naturally, the exposed portion 51a is close to the mounting base 52a and / or the end of the heater 50a.

[0203] Similarly, the distance between the exposed portion 51a of the heater 50a and the free front end is approximately 12 mm. Since the exposed portion 51a is far from the free front end, it is difficult for the cleaning device to directly clean the exposed portion 51a from the receiving port 41a of the extractor 40a.

[0204] Similarly, the support wall 421a is provided with a first hole 422a through which the heater 50a passes to the aerosol generating article A; and a second hole 423a for air to enter the aerosol generating article A.

[0205] During the suction process, the airflow is described in detail below. Figures 15 to 20 As shown by arrow R2, external air enters the window 32a through the gap between the support 30a and / or the shield 60a and the main housing 10a, and then enters the first air port 46a in the extractor 40a through the air supply window 32a into the receiving part 420a of the extractor 40a, and is then sucked into the aerosol-generated product A through the second hole 423a until it is drawn out.

[0206] As shown in the figure, in a preferred embodiment, the airflow channel includes an air inlet portion extending radially toward the heater 50a, and an air outlet portion extending longitudinally toward the proximal end 110a within the receiving cavity. The air inlet portion allows air to enter the extractor 40a through the supply window 32a via a first air port 46a, and the air outlet portion passes through a second hole 423a.

[0207] exist Figure 19 In the embodiment shown, the distance d3 between the supporting wall 421a and the front end of the receiving part 420a is approximately 3 to 5 mm.

[0208] Alternatively, in another variation, the blocking member 60a opens or blocks the window 32a by moving or rotating at different positions on the support 30a. For example, the blocking member 60a is configured to move along the length of the support 30a, thus blocking the window 32a when it moves closer to the second space 1200, and at least partially opening the window 32a when it moves away from the second space 1200. Of course, in many more variations, the blocking member 60a can also be along the width.

[0209] Further according to Figure 18 As shown, a first insulating cavity 34a is also defined within the bracket 30a; in terms of arrangement, the first insulating cavity 34a is located between the receiving cavity for receiving the aerosol-generated product A and the first space 1100 along the width direction, which is advantageous for preventing the heat from the heater 50a from being transferred to the cell 11a in the first space 1100.

[0210] In this optional embodiment, the first insulating cavity 34a is a closed space, which can then be filled with air to utilize the low thermal conductivity of air to create insulation. Alternatively, in some embodiments, the first insulating cavity 34a is evacuated to reduce its pressure to below the external pressure, thus creating insulation. Or, in still other embodiments, the first insulating cavity 34a is filled with porous materials, foam, aerogel, etc., to enhance insulation.

[0211] For the above-mentioned aerosol generating device 100, cleaning the debris or aerosol condensate that falls off the aerosol-generated product A may include:

[0212] Without removing the extractor 40a, the inner wall of the receiving part 420a and part of the surface of the heater 50a can be cleaned by inserting a brush or other tool through the receiving hole 41a.

[0213] After removing the extractor 40a, you can continue to clean the inner wall of the receiving space 31a by inserting a brush or other tools.

[0214] After removing the obstruction 60a, the exposed portion 51a of the heater 50a is exposed through the window 32a, and then a cleaning tool is inserted into the window 32a to clean the exposed portion 51a of the heater 50a.

[0215] After removing the screws from the first connecting hole 15a and the second connecting hole 16a with a screwdriver, remove the bracket 30a to expose the heater 50a completely, allowing cleaning tools to perform a deep and thorough cleaning of the surface of the heater 50a.

[0216] further Figures 21 to 24A schematic diagram of another embodiment of the aerosol generating device 100b is presented; in this embodiment, the aerosol generating device 100b is configured as a generally elongated cylindrical shape, having a length dimension of approximately 90 to 110 mm and an outer diameter dimension of approximately 15 to 20 mm.

[0217] The aerosol generating device 100b further includes a proximal end 110b and a distal end 120b opposite each other along the length direction; and:

[0218] First housing 10b, near the distal end 120b;

[0219] A second housing 15b adjacent to the proximal end 110b is also provided on the first housing 10b;

[0220] An extractor 40b located at the proximal end 110b is used to extract aerosol-generated article A; in this preferred embodiment, the extractor 40b is removed directly from the second housing 10b to extract aerosol-generated article A.

[0221] Further according to Figure 22 and Figure 23 As shown, a second housing 15b is also provided on the first housing 10b adjacent to the proximal end 110b; correspondingly, the extractor 40b includes an annular operating portion 410b and a cylindrical receiving portion 420b located within the operating portion 410b. In practice, a user can perform an extraction operation by applying force to the operating portion 410b with their finger; and the aerosol-generated article A is removably received in the receiving portion 420b through the receiving hole 41b defined by the operating portion 410b. In assembly, the operating portion 410b is disposed around the second housing 15b; in the operating state, the operating portion 410b abuts against the end of the second housing 15b facing the proximal end 110b, thereby being stably held on the second housing 15b; and the outer surface of the second housing 15b also serves to provide guidance during the user's extraction operation of the extractor 40b.

[0222] Further according to Figure 24 As shown, the receiving portion 420b has a support wall 421b for supporting the aerosol generating article A; the support wall 421b is provided with a first hole 422b for the sensor 50b to pass through into the receiving portion 420b so as to be inserted into the aerosol generating article A; the support wall 421b is also provided with a second hole 423b for air to enter the aerosol generating article A of the receiving portion 420b.

[0223] Furthermore, the second housing 15b is provided with:

[0224] The support 20b is generally tubular, extending along the length of the second housing 15b; and the support 20b is basically coaxially arranged with the second housing 15b and located inside the second housing 15b; a receiving space 210b is defined within the support 20b, and the receiving portion 420b of the extractor 40b is received in the receiving space 210b to form an operating state in which a heatable aerosol is generated to produce article A;

[0225] A magnetic field generator, such as an induction coil 30b surrounding the support 20b, is used to generate a changing magnetic field;

[0226] The sensor 50b is configured to be heated by a changing magnetic field to heat the aerosol-generating article A; the sensor 50b is preferably configured as a pin, needle or sheet shape extending at least partially axially into the receiving space 210b, which is advantageous for insertion into the aerosol-generating article A when the extractor 40b is received in the receiving space 210b.

[0227] Further according to Figure 24 The free tip of the sensor 50b is located in the receiving space 210b, and its end is held by a retainer 70b. Specifically, the retainer 70b includes a first retainer 71b and a second retainer 72b arranged sequentially from the inside to the outside along the radial direction of the sensor 50b; the first retainer 71b is preferably made of a low thermal conductivity ceramic such as zirconium oxide, and the second retainer 72b is preferably made of a low thermal conductivity organic polymer such as PEEK.

[0228] For further details on the design of the suction airflow, please refer to [link / reference]. Figures 21 to 24 As shown, a first air inlet 151b is provided on the second housing 15b. Specifically, the first air inlet 151b is located adjacent to the first housing 10b, and similarly, adjacent to the part where the operating portion 410b of the extractor 40b engages with the first housing 10b. After assembly, when the operating portion 410b is held in the second housing 15b, it covers the first air inlet 151b. However, when the aerosol is extracted to the extraction position by removal / movement or other operations to generate article A, the first air inlet 151b becomes exposed. In the operating position, the operating portion 410b of the extractor 40b and the first housing 10b have a joint gap of approximately 2 mm, and the first air inlet 151b is opposite to this gap, thus allowing airflow communication. During the suction process, external air enters the first air inlet 151b through the joint gap between the operating portion 410b and the first housing 10b.

[0229] The support 20b also has an inner bottom wall 221b defining the receiving space 210b; the inner bottom wall 221b has a gap or slit of approximately 1 to 3 mm with the mounting base 70b of the sensor 50b, and the inner bottom wall 221b also has a second air port 222b. In practice, the second air port 222b is opposite to the second hole 423b on the extractor 40b.

[0230] Then, during the suction process, external air enters the first air inlet 151b through the gap between the operating part 410b and the first housing 10b, as shown by arrow R2 in the figure. Then, it flows radially from the first air inlet 151b through the gap between the bottom wall 221b and the fixed seat 70b to the second air inlet 222b. Finally, it passes through the second hole 423b on the extractor 40b through the second air inlet 222b and enters the aerosol-generated product A before being suctioned.

[0231] As shown in the figure, the airflow path includes an intake portion extending radially from the first intake port 151b to the second intake port 222b along the sensor 50b; and an exhaust portion extending longitudinally from the second intake port 222b to the proximal end 110b. Essentially, the intake and exhaust portions are substantially perpendicular. However, in practice, the exhaust portion passes through the receiving portion 420b of the receiving space 210b and / or the extractor 40b.

[0232] For further, more preferred implementations, see [link to relevant documentation]. Figure 24 As shown, the second mounting base 72b has a locking protrusion 721b extending to the first air inlet 151b, which holds the second housing 15b within the first air inlet 151b; when disassembly is required, the locking protrusion 721b can be pressed to disengage from the first air inlet 151b, thereby allowing the second housing 15b to be detached or removed from the first housing 10b.

[0233] It should be noted that the preferred embodiments of this application are given in the specification and accompanying drawings, but are not limited to the embodiments described in this specification. Furthermore, those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
