Detailed Description

To facilitate an understanding of the present application, the present application is described in more detail below with reference to the accompanying drawings and detailed description.

An embodiment of the present application provides an aerosol-generating device for receiving an aerosol-generating article to generate an aerosol.

Further in alternative implementations, the aerosol-generating article preferably employs a tobacco-containing material that releases volatile compounds from the substrate upon heating; or it may be a non-tobacco material that is suitable for electrically heated smoking after heating. The aerosol-generating article preferably employs a solid substrate, which may comprise one or more of a powder, granules, shredded strips, strips or flakes of one or more of vanilla leaf, tobacco leaf, homogenised tobacco, expanded tobacco; alternatively, the solid substrate may contain additional tobacco or non-tobacco volatile flavour compounds to be released upon heating of the substrate.

Further in alternative implementations, the aerosol-generating article comprises a tobacco rod in the form of an elongate cylinder.

As further shown in fig. 1-2, in one embodiment the aerosol-generating device 100 is configured to be generally square in shape.

In the embodiment shown in fig. 1, the aerosol-generating device 100 comprises:

a proximal end 110 and a distal end 120 opposite along the length; the proximal end 110 is configured to be the end of a user inhaling the aerosol, according to the requirements of normal use, in which the aerosol-generating article is received at least partially into the aerosol-generating device 100 through the proximal end 110 and heated to generate the aerosol.

Further in accordance with fig. 1 and 2, the aerosol-generating device 100 defines:

a first space 1100 extending substantially from the proximal end 110 to the distal end 120; and the first space 1100 is located at one side of the aerosol-generating device 100 in the width direction; in use, the first space 1100 is a space for accommodating and assembling the battery cell 11 for supplying power;

a second space 1200 located substantially near the distal end 120 and opposite or adjacent to a portion of the first space 1100 in the width direction; in use, the second space 1200 is a space for receiving and mounting a circuit board such as a PCB board;

a third space 1300 located substantially near the proximal end 110 and being opposite to the second space 1200 in the length direction and opposite to or adjacent to a portion of the first space 1100 near the proximal end 110 in the width direction; in use, the third space 1300, at least partially defining a heating space, is to receive and heat at least a portion of an aerosol-generating article to generate an aerosol for smoking.

In a preferred implementation, first space 1100, second space 1200 and third space 1300 are particularly hermetically sealed from one another to prevent the flow of hot air or aerosol in front of them.

Referring further to fig. 3, fig. 3 shows a schematic view of an aerosol-generating system comprising the aerosol-generating device 100 in combination with an article cartridge 200. As shown in fig. 3, article case 200, such as a cigarette case, is generally configured in the shape of a square; article carton 200 typically has an openable flap 300, by which opening flap 300 aerosol-generating articles, such as cigarettes, contained within article carton 200 may be accessed.

As further shown in fig. 3, aerosol-generating device 100 may be substantially similar in shape and volume to article case 200, such as a cigarette case, and may be advantageously placed in combination with article case 200.

As further shown in fig. 3, the outer surface of the aerosol-generating device 100 has a plurality of flat surfaces, and the flat surface with the largest area is a side surface that is flat on both sides in the thickness direction; the article case 200, such as a cigarette case, also has planar side surfaces on both sides in the thickness direction, which are the planes having the largest areas. When the side surfaces of the aerosol-generating device 100 in the thickness direction are combined with the side surfaces of the article case 200 in the thickness direction, their contact area is defined by the plane of the two having the smaller area.

Of course in some implementations, the area or shape of the largest plane on the outer surface of the aerosol-generating device 100 is substantially the same as or close to the largest plane on the outer surface of the article case 200. Or in some implementations, the area or shape of any side surface of the aerosol-generating device 100 in the thickness direction is substantially the same as or close to the area or shape of any side surface of the article case 200 in the thickness direction.

Also according to the illustration in figure 3, the side surface of the aerosol-generating device 100 that contacts or joins the article case 200 is square; and any other side surface of the aerosol-generating device 100 adjacent to the side surface contacting the article cartridge 200 is square; for example, in fig. 3, the side surfaces of the aerosol-generating apparatus 100 in the longitudinal direction or the width direction are square.

Also according to figure 3, when the aerosol-generating device 100 is joined to the article case 200 in the thickness direction, the side surface of the aerosol-generating device 100 facing away from the article case 200 in the thickness direction and the side surface of the article case 200 facing away from the aerosol-generating device 100 are exposed. In use, a user can hold the aerosol-generating device 100 and the article case 200 by fingers while gripping the side surface of the mist-generating device 100 facing away from the article case 200 in the thickness direction and the side surface of the article case 200 facing away from the aerosol-generating device 100; and thus is advantageous for portability.

As shown in fig. 3, the aerosol-generating device 100 and the article case 200 have substantially similar shapes and dimensional volumes. In practice, the article case 200 has a length dimension of about 70-80 mm, a width dimension of about 40-50 mm, and a thickness dimension of about 10-20 mm.

As shown in fig. 3, the corresponding aerosol-generating device 100 may have a length L of about 70-80 mm, a width W of about 40-50 mm, and a thickness H of about 9.5-20 mm. In practice, the surfaces of the aerosol-generating device 100 on both sides in the thickness direction are the largest plane and have an area of about 2800mm ² ～4000mm ² 。

Further in some alternative implementations, the extended 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 1/3 to 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 implementations, the first space 1100 also has a length dimension of about 60-65 mm, a width dimension of about 15-25 mm, and a thickness dimension of about 5-10 mm.

Accordingly, as shown in fig. 2, the battery cell 11 accommodated or fitted in the first space 1100 is configured to have a substantially square shape. Accordingly, in some implementations, the volume or shape of the cell 11 is substantially the same as or close to the first space 1100. In some implementations, the cells 11 have a length of about 60-65 mm, a width of about 15-25 mm, and a thickness of about 5-10 mm.

Further in some alternative implementations, the second space 1200 has a length dimension of about 35-50 mm, a width dimension of 15-25 mm, and a thickness dimension of about 5-10 mm.

Further in some alternative implementations, the third space 1300 has a length dimension of about 25mm to 40mm, a width dimension of 15 to 25mm, and a thickness dimension of about 5 to 10 mm.

In further 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.

The thickness of the second space 1200 and/or the third space 1300 is substantially close to the thickness H of the aerosol-generating device 100.

In still other implementations, the extended length of the second space 1200 is greater than the extended length of the third space 1300. In still other implementations, the second space 1200 extends between 1/2 and 2/3 of the length of the aerosol-generating device 100. In still other implementations, the third space 1300 extends between 1/3 and 1/2 of the length of the aerosol-generating device 100.

As further shown in fig. 4, in yet another alternative implementation, a wireless charging coil 1400 is disposed within aerosol-generating device 100 proximate to at least one side in the thickness direction; this wireless charging coil 1400 can be used for coupling with the external wireless charging device, and then receives the electromagnetic energy of wireless charging device and produces charging current and then charges electric core 11.

As further shown in fig. 4, the wireless charging coil 1400 for wirelessly charging the battery cell 11 is a planar spiral coil. In some implementations, wireless charging coil 1400 is a generally square planar spiral coil, as shown in fig. 4. Or in some implementations, wireless charging coil 1400 may also be configured as a circular, planar spiral coil.

In some alternative implementations, wireless charging coil 1400 is made of wire material that is circular, or rectangular in cross-section; examples of such a wire material include a general copper wire and a general nickel wire. Or in yet other alternative implementations, the planar spiral coil of the wireless charging coil 1400 is in the form of a deposited, printed, etched coating, trace, or wire; for example, wireless charging coil 1400 is in the form of a planar spiral coil of conductive material formed by printing, depositing, etc. a coating or wire on a substrate. Or in yet other alternative implementations, the planar spiral coil of wireless charging coil 1400 is in the form of a planar spiral coil etched or cut from a sheet of metal conductive substrate.

Further figures 5 to 7 show schematic views of an aerosol-generating device 100 according to an embodiment, in which the aerosol-generating device 100 comprises:

a main housing 10, the main housing 10 mainly serving as an outer housing part of the aerosol-generating device 100, thereby defining the above first space 1100, second space 1200 and third space 1300 inside thereof; in practice, therefore, the main housing 10 is substantially the same as the external shape and dimensional requirements of the aerosol-generating device 100 described above.

A door 20 located at the proximal end 110 of the main housing 10 and/or aerosol-generating device 100 and configured to be movable relative to the main housing 10 in an implementation; of course, according to the preferred embodiment shown in fig. 5 and 6, the movement of the door 20 relative to the main housing 10 is a sliding movement in the width direction of the main housing 10, as indicated by the arrow R1 in fig. 6; or in other variations, the movement of the door 20 relative to the main housing 10 may be in the form of rotation about an axis.

As shown in fig. 5 to 7, the door 20 is movably designed to have an open position and a closed position. Wherein the door 20 is in a closed position, such as shown in figure 5, the door 20 forms a barrier or enclosure to the third space 1300 when the aerosol-generating device 100 is locked out of use; the door 20 in the open position, as shown for example in figures 6 and 7, exposes the third space 1300 so that a user can receive an aerosol-generating article a into the aerosol-generating device 100 for inhalation and cleaning of the third space 1300.

As further shown in fig. 5 to 7, the main housing 10 is provided with a guide groove 11 for guiding the moving process of the door 20. Specifically, in a preferred embodiment, the guide groove 11 is provided on a side surface of the main housing 10 in the thickness direction; and the guide groove 11 is configured as an elongated groove extending in the width direction of the main housing 10. In use, the door cover 20 extends at least partially into the guide slot 11, thereby cooperating with the guide slot 11 to form a guide for the movement process; and, the end positions of both ends of the guide groove 11 are used for providing a limit to the movement of the door cover 20.

In the embodiment shown in the figures, the guide groove 11 has a length of approximately 30-40 mm.

The shape or configuration of the door 20 can be seen in fig. 8, and the door 20 includes:

a first blocking wall 210 substantially in parallel with the upper side of the main casing 10; a third space 1300 is shielded or closed at the proximal end 110 in a use state in the closed position;

the second and

third shielding walls

220 and 230 extend along the length direction of the main housing 10, and the second and

third shielding walls

220 and 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 to be located at both sides in the thickness direction of the main casing 10; further, in use, the second shielding wall 220 and the third shielding wall 230 shield or enclose the third space 1300 from both sides in the thickness direction of the main housing 10, respectively.

Further, a first hook 221 is disposed at an end of the second shielding wall 220 away from the first shielding wall 210, and/or a second hook 231 is disposed at an end of the third shielding wall 230 away from the first shielding wall 210; in use, the first hook 221 and/or the second hook 231 at least partially extend into the guiding groove 11, and remain connected to the main housing 10 while cooperating to provide a guide, so as to prevent the first hook 221 and/or the second hook 231 from falling out of the guiding groove 11 and the door 20 from falling off the main housing 10.

In a preferred embodiment shown in fig. 8, the first shielding wall 210 and/or the second shielding wall 220 and/or the third shielding wall 230 have a rectangular shape. In a more preferred implementation, the first shielding wall 210 has a length dimension of about 15-25 mm and a width dimension of about 5-10 mm. And, the second shielding wall 220 and/or the third shielding wall 230 has a length dimension of about 28mm to 40mm and a width dimension of about 15 to 25 mm.

In a more preferred embodiment, the door 20 is made of a material with high thermal conductivity, such as a metal material, which is advantageous for promoting heat dissipation of the heating element in the third space 1300 and uniform heat transfer to other parts.

As further shown in fig. 6 and 7, the aerosol-generating device 100 includes:

a receiving aperture 41 at the proximal end 110, through which receiving aperture 41 an aerosol-generating article a may be at least partially received within the aerosol-generating device 100.

In the preferred implementation shown in fig. 10, the receiving aperture 41 is defined by the extractor 40. Or in other variations, when the aerosol-generating device 100 does not have the extractor 40, the receiving aperture 41 may also be defined by the main housing 10, or the bracket 30, or the like.

Referring also to fig. 10, aerosol-generating device 100 includes:

a receiving cavity 430 within which at least a portion of the aerosol-generating article a is removably received; the receiving cavity 430 is in communication with the receiving hole 41.

In the preferred implementation shown in fig. 10, the receiving chamber 430 is also defined by the extractor 40. Or in other variations, when the aerosol-generating device 100 does not have the extractor 40, the receiving chamber 430 may also be defined by the main housing 10, or the support frame 30, or the like.

As further shown in fig. 9 and 10, aerosol-generating device 100 includes:

a heater 50 configured in the shape of a pin, a needle, a sheet, or the like, such as the needle shown in fig. 9; for heating when the aerosol-generating article a is received within the aerosol-generating device 100, the heater 50 can be inserted into the aerosol-generating article a. In some alternative implementations, pin or needle heater 50 has a length dimension of about 12-19 mm and an outer diameter dimension of about 2-5 mm. In still other alternative implementations, the sheet-like heater 50 may have a length dimension of about 12-19 mm, a width dimension of about 3-6 mm, and a thickness dimension of about 0.4-1 mm. Accordingly, as shown in fig. 10, the heater 50 extends at least partially within the receiving cavity 430, which is advantageous for heating upon insertion into the aerosol-generating article a.

In other modified embodiments, the heater 50 may also be configured in a cylindrical shape; the interior space thereof defines, in use, a receiving chamber 430 for receiving the aerosol-generating article a and generating an aerosol by means of heating of the periphery of the aerosol-generating article a.

In some alternative implementations, the heater 50 is a resistive heater; or in some implementations, the heater 50 is a susceptor that is penetrated by a magnetic field to generate heat.

As further shown in fig. 9 and 10, the aerosol-generating device 100 comprises:

a support 30, in operation, supports the extractor 40. Meanwhile, the supporter 30 is also configured to surround or shield the heater 50. Specifically, the method comprises the following steps:

the holder 30 is, on the one hand, detachably arranged in the third space 1300, and is supported or held by the holder 30 when the extractor 40 is connected to the aerosol-generating device 100. On the other hand, the bracket 30 at least partially surrounds or shields the heater 50, so that the heater 50 is at least prevented from being completely exposed to the third space 1300, which is advantageous for preventing a user from touching or touching.

In a preferred implementation, the bracket 30 has a generally square profile. In practice, a particular stent 30 has a length dimension of about 25mm to 40mm, a width dimension of 15 to 25mm, and a thickness dimension of about 5 to 10 mm.

As further shown in fig. 9 and 10, the extractor 40 includes:

a cylindrical receiving portion 420, an interior space of the receiving portion 420 being configured as a receiving cavity 430 for receiving an aerosol-generating article a;

an operating portion 410, which operating portion 410 is operated by a user with a finger or the like in use to move or remove the extractor 40 to extract the aerosol-generating article a. When the extractor 40 is fitted into the aerosol-generating device 100, the extractor 40 is connected to the main housing 10 via the operating portion 410, thereby stably holding the extractor 40 on the aerosol-generating device 100. Of course, in some implementations, the operation portion 410 may be directly or indirectly connected to the main housing 10. Or in the preferred embodiment of figures 9 and 10, the handle portion 410 is secured and retained within the aerosol-generating device 100 by abutting and attaching to the upper end of the holder 30.

Further in a more preferred implementation, the extractor 40 is movable or removable with respect to the main housing 10, so as to assume a relative operating position and extraction position. Specifically, the method comprises the following steps:

figure 11 shows a schematic view of the extractor 40 in an operating position in which the aerosol-generating article a is received in the receiving portion 420 and supported by the retaining wall 421 of the receiving portion 420, in one embodiment; the heater 50 penetrates at least partially through the seating wall 421 into the receiving cavity 430 defined by the receiving portion 420, thereby heating the aerosol-generating article a. The operating position is substantially the operating position formed by the insertion of the heater 50 into the aerosol-generating article a. In this operative position, the extractor 40 remains connected to the main housing 10.

Fig. 12 shows a schematic view of the extractor 40 in an extraction position in which the extractor 40 is removed by being moved or removed lengthwise relative to the main housing 10 by operation of the operating portion 410, thereby separating the aerosol-generating article a from the heater 50 on support of the supporting wall 421, in one embodiment. The extraction location is formed by the aerosol-generating article a being separate from the heater 50.

In an alternative implementation, the extractor 40 is also directly or indirectly in contact with the main housing 10 in the extraction position, which is advantageous to prevent the extractor 40 from disengaging from the aerosol-generating device 100. Or in yet another alternative implementation, the extractor 40 is not directly or indirectly connected to the main housing 10 in the extraction position, and the extractor 40 is then advantageously detached from the main housing 10 and/or the support frame 30 in the extraction position, thereby facilitating removal or detachment directly from within the aerosol-generating device 100.

In an alternative implementation, the aerosol-generating article a has a length of from about 40 to 80 mm; and an outer diameter dimension of about 4 to 8mm.

In yet another preferred implementation, the receiving portion 420 of the extractor 40 has a length of approximately 15-40 mm; and the receiving portion 420 correspondingly has an inner diameter of about 4 to 8mm.

As further shown in fig. 13, the extractor 40 further includes:

a first hole 422, which is located on the supporting wall 421 and has an inner diameter substantially matching and slightly larger than that of the heater 50, so that the heater 50 can be inserted into the receiving portion 420 after passing through the first hole 422; when adapted to a pin or needle heater 50, such as shown in fig. 13, the first bore 422 is circular and has an inner diameter of about 3-6 mm.

Second holes 423, located in the supporting wall 421, are intended to allow the external air to enter the aerosol-generating article a during the suction process, as indicated by the arrow R2 in figure 13, through the second holes 423. In practice, the second holes 423 have an inner diameter of about 1 to 2mm. Meanwhile, the second holes 423 may be several in number and arranged around the first holes 422.

As further shown in fig. 9 and 10, the configuration of the stent 30 includes:

left and

right side walls

310 and 320 facing away from each other in the width direction; in assembly, the left sidewall 310 is a sidewall adjacent to the first space 1100, and is detachably coupled to the main housing 10 by a snap or the like; right side wall 320 is at least partially exposed outside of aerosol-generating device 100 after assembly and at least partially defines the outer surface of aerosol-generating device 100 in the width direction;

a lower end wall 350 adjoining the second space 1200 in the length direction, the lower end wall 350 having a third hole 33 formed therein, the heater 50 penetrating the third hole 33 from below into the bracket 30 in the length direction in the assembly;

front and rear side walls 330 and 340 are provided opposite to each other in the thickness direction, and a window 32 is provided in the front and rear side walls 330 and 340 near the lower end wall 350. In an alternative implementation, the front and rear side walls 330, 340 are unconnected or in contact with the lower end wall 350. In implementation, the window 32 is defined by a spacing between the front sidewall 330 and/or the rear sidewall 340 and the lower sidewall 350.

In an implementation, the window 32 is directly communicated with the outside air, and the second hole 423 of the extractor 40 may be communicated with the outside air through the window 32; then during smoking, outside air passes directly through the window 32 into the second aperture 423 and then into the receiving cavity 430 to be smoked by the user with the aerosol generated by the aerosol-generating article a, as indicated by the arrow R2 in figure 10.

As further shown in fig. 9, 10 and 14, the free front end of the heater 50 is penetrated into the holder 30; the end of the heater 50 facing away from the free front end is fixed within the main housing 10. Further according to the implementation shown in the figures, the end of the heater 50 facing away from the free front end is surrounded and fixed by a fixing seat 52.

And the heater 50 has an exposed portion 51 exposed to the window 32; the exposed part 51 of course has a length of about 2-5 mm. The exposed portion 51 of the heater 50 is visible through the window 32. Of course, when assembled, the exposed portion 51 is defined by the size or location of the window 32. Specifically, in this embodiment, the fixed seat 52 is covered and shielded by the lower end wall 350 of the bracket 30, and the exposed portion 51 of the heater 50 is completely defined by the bracket 30; and in particular, by the portion of the heater 50 lengthwise between the lower end walls 350 of the front and/or rear side walls 330,340.

Of course, the exposed portion 51 is near the end of the holder 52 and/or the heater 50. As can be seen from fig. 14, the distance d4 of the exposed part 51 of the heater 50 from the free front end is about 12mm. The exposed portion 51 is remote from the free front end, and it is difficult for the cleaning implement to directly clean the exposed portion 51 from the receiving aperture 41 of the extractor 40. In a typical implementation, the distance d4 of the exposed portion 51 of the heater 50 from the free front end is greater than 8mm.

In yet another embodiment, the window 32 has a suitable area such that, in use, the exposed portion 51 of the heater 50 can be cleaned by some cleaning implement extending into the window 32. In some implementations, the cleaning implement is, for example, a small brush, or a wire strip, or a wiper blade, or the like.

In some preferred implementations, the window 32 must be of a suitable area to provide the necessary size for the cleaning implement to extend into, and also to prevent the user's fingers from extending into, the window to prevent burning by the heater 50.

In a preferred implementation, the window 32 has a width greater than 10mm ² And an area of less than 100mm ² The area of (a). In a more preferred implementation, the window 32 has a width greater than 30mm ² In an area of less than 80mm ² The area of (a).

In the preferred embodiment shown in fig. 9 and 14, the window 32 is substantially square in shape. For example, the window 32 is elongated in the width direction of the holder 30. In a more preferred embodiment, the window 32 has a length dimension d1 extending in the width direction of the bracket 30 of about 10-20 mm; and the width dimension d2 of the window 32 extending in the lengthwise direction of the holder 30 is about 3 to 6mm.

In one particular implementation shown in FIG. 14, the window 32 has a length dimension d1 of 17mm; and the width dimension d2 of the window 32 is about 4.2mm.

And in yet another alternative implementation, at least one of the length dimension d1 and the width dimension d2 of the window 32 should not be greater than 10mm, which is advantageous for preventing a user's finger from reaching in. In a more preferred implementation, at least one of the length dimension d1 and the width dimension d2 of the window 32 must not be greater than 6mm.

The length of the exposed portion 51 of the heater 50 is substantially 3-6 mm, correspondingly. In a preferred embodiment, the length of the heater 50 penetrating into the receiving portion 420 of the extractor 40 is about 10 to 18mm. In a preferred implementation, the length of the exposed portion 51 of the heater 50 is no more than 1/3 of the total length of the heater 50.

As further shown in fig. 9 and 10, to facilitate guidance of the extractor 40 during assembly, movement or removal operations with the support 30; the holder 30 also has a first inner wall 360 and a second inner wall 370. According to the illustration, the first inner wall 360 and the second inner wall 370 are configured in the shape of arcs, and the first inner wall 360 and the second inner wall 370 are opposite. And the first and second

inner walls

360 and 370 are arc-shaped bent outward in the width direction to define the guide receiving space 31 therebetween. The receiving space 31 has substantially the same shape as the receiving portion 420 of the extractor 40, and the receiving space 31 has a size slightly larger in volume than the receiving portion 420, so that the first and second

inner walls

360 and 370 provide a guide when the extractor 40 is stably mounted to the bracket 30 and during movement or removal.

Or in yet another variant implementation, when the aerosol-generating device 100 does not have the extractor 40 component, then the receiving cavity 430 for receiving the aerosol-generating article a is configured by the receiving space 31 between the first inner wall 360 and the second inner wall 370.

Also according to fig. 5 and 6, the door 20 is in the closed position to obstruct or close the window 32; and, the door 20 is open or reveals the window 32a in the open position.

In the preferred embodiment shown in fig. 9 and 10, the first inner wall 360 is spaced from the left side wall 310 of the bracket 30 to form the first insulating chamber 34 therebetween; the second inner wall 70 is spaced from the right side wall 320 of the rack 30 to form a second insulating chamber 35 therebetween.

In the embodiment shown in the figures, the first insulating chamber 34 and/or the second insulating chamber 35 are empty and open, communicating with the outside air, thus forming an insulation by the low thermal conductivity of the air; the first insulating cavity 34 is used for preventing heat of the heater 50 from being transferred to the electric core 11 of the first space 1100 radially outwards; and/or the second insulating chamber 35 prevents heat of the heater 50 from being transferred radially outward to the right sidewall 320.

In some variant implementations, the first insulating chamber 34 and/or the second insulating chamber 35 are closed chambers, and thus their internal pressure can be configured to be lower than the external pressure, i.e. the first insulating chamber 34 and/or the second insulating chamber 35 have a vacuum; it is advantageous for preventing heat transfer.

Or in yet other variations, the first insulating cavity 34 and/or the second insulating cavity 35 are filled with some insulating material, such as aerogel, porous polymer, porous polyurethane, foam, etc.; it is advantageous for preventing heat transfer.

As further shown in fig. 9 and 10, the receiving portion 420 of the extractor 40 is also at least partially exposed through the window 32.

Further, in the preferred embodiment shown in fig. 10, a circuit board 12 for controlling the operation of the gas mist generating device 100 is installed in the second space 1200 of the gas mist generating device 100; and a charging interface 13 at the distal end 120 for electrically connecting, in use, to the circuit board 12 to charge the cell 11 after connection to an external power supply.

With the aerosol-generating device 100 above, cleaning of debris or aerosol condensate dropped by the aerosol-generating article a may comprise:

when the extractor 40 is not removed, the inner wall of the receiving portion 420 and a part of the surface of the heater 50 may be projected from the receiving hole 41 to be cleaned by means of a brush or the like;

after the extractor 40 is removed, the device such as a brush can be continuously inserted into the inner wall of the accommodating space 31 for cleaning; and through the window 32 into the exposed portion 51 of the heater 50 for cleaning;

the support frame 30 is further removed from the main housing 10, as shown in fig. 9, to substantially completely expose the heater 50, so that the surface of the heater 50 can be deeply and completely cleaned by the cleaning implement.

Further figures 15 to 18 show schematic structural views of yet another embodiment of the aerosol-generating device 100; in this implementation, the aerosol-generating device 100 comprises:

a main housing 10a;

a door 20a positioned at the proximal end 110a of the main housing 10a and movable between an open position and a closed position relative to the main housing 10a; such as movement in the width direction of the main housing 10a, or rotation, etc.

Referring also to fig. 18, the aerosol-generating device 100 further comprises a stop projection 17a located between the main housing 10a and the door cover 20 a; in assembly, the stop protrusion 17a is located at the proximal end 110a of the main housing 10a and is at least partially convex with respect to the main housing 10 a. The stopper projection 17a serves to provide a stopper at the open position and the closed position of the door cover 20a when the door cover 20a moves in the width direction with respect to the main casing 10 a. In a more preferred embodiment, the door 20a covers or hides the position-limiting protrusion 17a in any position of movement. The restricting projection 17a is not exposed on the surface of the aerosol-generating device 100 at any moving position of the door 20 a.

And, the aerosol-generating device 100 further comprises:

a bracket 30a at least partially defining a window 32a with the main housing 10a; the heater 50a is at least partially exposed within the window 32a;

an extractor 40a supported and held by the support 30 a; in use the extractor 40a is used to extract an aerosol-generating article a received within the aerosol-generating device 100 a.

As further shown in fig. 16, in order to facilitate the stable connection of the extractor 40a to the support 30a in the operating position, the extractor 40a is provided with a snap projection 43a; the engaging projection 43a is used to engage and connect the extractor 40a with the holder 30a at the operating position. In the preferred embodiment shown in fig. 16, the catching protrusion 43a is several in number and is constructed in the form of a rib located at the outer surface of the receiving portion 420a of the extractor 40 a.

In this embodiment, the extractor 40a further extracts the aerosol-generating article a by operation of direct lengthwise removal from the holder 30a, as indicated by the arrow R3 in figure 16.

As further shown in fig. 16, the bracket 30a is provided with a first connection hole 15a and/or a second connection hole 16a, although the first connection hole 15a is disposed adjacent to the first space 1100. In use, screw/bolt/screw or the like coupling members couple the bracket 30a with the main housing 10a by being mounted in the first coupling hole 15a and/or the second coupling hole 16 a. Specifically, the first connection hole 15a is disposed adjacent to the proximal end 110 a; the second connection hole 16a is disposed adjacent to the second space 1200.

Further according to the preferred implementation shown in the figures, the first connection hole 15a is covered or hidden by the extractor 40a when the extractor 40a is held on the support 30 a. Specifically, the first connection hole 15a is covered by the operation portion 41a of the extractor 40 a. And after removing the extractor 40a, the first connection hole 15a is exposed, and the user can detach the screw/bolt/screw connection member located in the first connection hole 15a by means of a screwdriver or the like; further, the connection between the holder 30a and the main casing 10a is released, and the holder 30a is detachable from the main casing 10 a.

And, the second connection hole 16a is exposed to the window 32a; alternatively, second attachment aperture 16a is visible through window 32a; the user can remove the screw/bolt/screw connection member by inserting the screwdriver into the second connection hole 16a through the window 32a.

As further shown in fig. 15-17, the aerosol-generating device 100 of this example further comprises:

a shutter 60a for blocking or covering or closing the window 32a; further, when suction, safety protection, or the like does not require opening of the window 32a, the window 32a is shielded or covered or closed by the shutter 60 a. When it is necessary to clean the exposed portion of the heater 50a exposed to the window 32a or to detach the screw/bolt/screw connecting member in the second connecting hole 16a, the window 32a may be opened by moving or removing the shielding member 60 a.

In further accordance with the preferred embodiment shown in fig. 15-17, the shield 60a shields or conceals or closes the window 32a by being removably coupled to the bracket 30 a. When the shutter 60a is coupled to the bracket 30a, the window 32a is shielded or covered or closed. And when the shutter 60a is removed from the bracket 30a, the window 32a is opened.

As further shown in fig. 15 to 17, when the shutter 60a is coupled to the bracket 30a, the shutter 60a is in flat engagement with the surface of the bracket 30 a.

In the preferred embodiment shown in the drawings, the shutter 60a is coupled to the support frame 30a in the width direction of the main housing 10a, or is removed from the support frame 30a in the width direction of the main housing 10 a.

In a more preferred embodiment, the main housing 10a is further provided with a guide rail 14a extending in the width direction; a guide groove 65a is provided on the corresponding shutter 60a to provide a guide in an operation of attaching or removing the shutter 60a to or from the bracket 30 a.

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

As further shown in fig. 20, of the open dimensions of the window 32a on both sides in the thickness direction, the length dimension d11 is 20mm; and a width dimension d12 of 6mm.

In this embodiment, the window 32a is at least partially defined by the shelf 30 a. Specifically, it is defined by a space between the bracket 30a and the main housing 10a in a length direction.

As further shown in fig. 16 and 17, the bracket 30a also defines a receiving space 31a for at least partially receiving the extractor 40 a. The receiving space 31a is extended in a length direction and has substantially the same shape as the receiving portion 420a of the extractor 40a, and the receiving space 31a has a size slightly larger in volume than the receiving portion 420a, so that the inner wall of the receiving space 31a serves to provide a guide when the extractor 40a is stably assembled to the bracket 30a and during movement or removal.

Likewise, a receiving cavity for receiving the aerosol-generating article a is defined by the receiving portion 420a of the extractor 40a in the above implementation. Whereas the receiving space 31a is primarily intended to serve as a receiving chamber for receiving the aerosol-generating article a when no components of the extractor 40a are present.

As further shown in fig. 16 and 17, the bracket 30a has a convex portion 34a that protrudes in the width direction away from the first space 1100, and a concave portion 33a is defined between the convex portion 34a and the other portion of the bracket 30 a. Of course, as shown, the projection 34a is located at the proximal end 110a such that the recess 33a is formed adjacent the window 32a.

According to the figure, the accommodation space 31a is kept away from the projection 34 a.

Correspondingly, the shutter 60a includes a main body portion 61a extending in the length direction, and first and

second shutter arms

62a and 63a extending in the width direction substantially from both sides of the thickness of the main body portion 61 a. After assembly, the first shielding arm 62a and the second shielding arm 63a respectively cover, shield, 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. And, after assembly, the body portion 61a is received and retained within the recess portion 33 a; and the surface of the shutter 60a is in flat engagement with the bracket 30 a.

According to the drawing, the guide groove 65a is formed on the first shielding arm 62a and/or the second shielding arm 63a.

As further shown in fig. 18, the bracket 30a is further provided with a first magnetic member 36a; of course, in a preferred embodiment, the first magnetic member 36a is disposed within the protruding portion 34 a.

Accordingly, the shielding member 60a is further provided with a second magnetic member 64a for magnetically attracting the first magnetic member 36a when the shielding member is combined with the bracket 30a to shield the window 32a, so that the shielding member 60a is stably held on the bracket 60 a. In a preferred embodiment, the second magnetic member 64a is received in the body portion 61a of the shield 60 a.

Accordingly, the extractor 40a is provided with a third magnetic member 45a for magnetically attracting the first magnetic member 36a in the operating position, thereby stably holding the extractor 40a on the bracket 60 a.

Further according to the preferred embodiment shown in the figures, the first magnetic member 36a, the second magnetic member 64a and the second magnetic member 45a have their magnetic pole arrangement directions identical along the length direction after assembly. For example, in the preferred embodiment shown in the figures, the first magnetic element 36a has a first magnetic pole, e.g., an N-pole, toward the proximal end 110a and a second magnetic pole, e.g., an S-pole, toward the distal end 120 a. And, the second magnetic element 64a also has a first magnetic pole, e.g., an N-pole, toward the proximal end 110a and a second magnetic pole, e.g., an S-pole, toward the distal end 120 a. Correspondingly, the third magnetic element 45a also has a first magnetic pole, e.g., N-pole, toward the proximal end 110a and a second magnetic pole, e.g., S-pole, toward the distal end 120 a.

The attraction of the first magnetic member 36a can be magnetically attracted to the second

magnetic members

64a and 45a located at the upper and lower sides at the same time after the assembly.

As further shown in fig. 19 and 20, the receiving portion 420a of the extractor 40a has a relatively longer length. Further, when assembled, the receiving portion 420a of the extractor 40a completely covers the heater 50a, and thus the heater 50a is not visible when the extractor 40a is coupled to the support 30 a. In a particular implementation, the front end of the receiving portion 420a abuts against the upper surface 521a of the fixed seat 52a facing the proximal end 110 a.

Further provided at the front end of the receiving portion 420a of the extractor 40a is a first air port 46a through which air of the window 32a enters the extractor 40a for entry of air into the receiving portion 420 a.

In this implementation, the receiving portion 420a has a supporting wall 421a therein for providing support to the aerosol-generating article a. As further shown in fig. 18 and 19, the extractor 40a also has an extension wall 424a extending from the receiving portion 420a, the extension wall 424a abutting against an upper surface 521a of the anchor 52a during assembly. In use, the extension wall 424a can shield the exposed portion 51a surrounding and exposing the heater 50a to the window 32a; on the other hand, and more importantly, a certain space is formed between the fixed seat 52a and the holding wall 421a through the extension wall 424a to block or retain the aerosol seeping or leaking through the first hole 422a and/or the second hole 423a, which is advantageous for preventing the aerosol from being visually observed by the user after seeping or leaking through the first hole 422a and/or the second hole 423a.

Of course, after the extractor 40a is moved or removed from the holder 30a to extract the aerosol-generating article a, the extension wall 424a is open to the exposed portion 51a of the heater 50a, so that the user can clean the exposed portion 51a of the heater 50a through the window 32a using the cleaning appliance.

Accordingly, the first port 46a is formed in the extension wall 424 a.

Further in this embodiment, as shown in fig. 16, the exposed portion 51a of the heater 50a is defined by the bracket 30a and the fixing seat 52a fixing the end of the heater 50 a. Specifically, in this embodiment, the exposed portion 51a is defined by a portion of the heater 50a between the bracket 30a and the fixing seat 52 a. Of course, the exposed portion 51a is near the end of the holder 52a and/or the heater 50 a.

Likewise, the exposed portion 51a of the heater 50a is spaced from the free front end by a distance of about 12mm. The exposed portion 51a is remote from the free front end, and it is difficult for the cleaning implement to directly clean the exposed portion 51a from the receiving hole 41a of the extractor 40 a.

Similarly, the supporting wall 421a is provided with a first hole 422a through which the heater 50a penetrates the aerosol-generating article a; and second apertures 423a for air to enter the aerosol-generating article a.

Then during the drawing, the flow of the air stream is seen by the arrow R2 shown in fig. 15 to 20, and the outside air enters the window 32a from the bracket 30a and/or the gap between the shutter 60a and the main housing 10a, and then enters the receiving portion 420a of the extractor 40a from the first air port 46a for the air of the window 32a to enter the extractor 40a, and is sucked into the aerosol-generating article a through the second hole 423a until being drawn.

In a preferred embodiment, the gas flow channel includes a gas inlet portion extending radially toward the heater 50a along the heater 50a, and a gas outlet portion extending lengthwise within the receiving chamber toward the proximal end 110a, as shown. Of course, the inlet portion is through the first air port 46a in which the air of the window 32a enters the extractor 40a, and the outlet portion is through the second hole 423a.

In the embodiment shown in fig. 19, the distance d3 between the support wall 421a and the front end of the receiving portion 420a is approximately 3 to 5mm.

Or in yet another alternative implementation, the shield 60a is moved or rotated to open or block the window 32a at different positions on the bracket 30 a. For example, the shutter 60a is configured to move lengthwise on the bracket 30a, to block the window 32a when moved to be close to the second space 1200, and to at least partially open the window 32a when moved to be away from the second space 1200. Of course, in more varied implementations, the shield 60a could also be widthwise.

As further shown in fig. 18, a first insulating cavity 34a is also defined within the support 30 a; it is advantageous to arrange that the first insulating cavity 34a is located, in the width direction, between the receiving cavity that receives the aerosol-generating article a and the first space 1100, for inhibiting heat transfer from the heater 50a to the cells 11a of the first space 1100.

In this alternative embodiment, the first insulating chamber 34a is a closed space, and thus the inside thereof may be filled with air, thereby forming an insulation using low heat conduction of air. Or in yet other implementations, the first insulating cavity 34a is insulated by drawing a vacuum to a pressure lower than the external pressure. Or in other embodiments, the first insulating cavity 34a is filled with a porous body, foam, aerogel, etc. to improve the insulation.

when the extractor 40a is not removed, the inner wall of the receiving portion 420a and a part of the surface of the heater 50a may be cleaned by protruding the receiving hole 41a through a brush or the like;

after the extractor 40a is removed, the inner wall of the accommodating space 31a can be cleaned by extending the brush and other tools into the inner wall;

after the shutter 60a is continuously removed, the exposed portion 51a of the heater 50a is exposed through the window 32a, and then the exposed portion 51a of the heater 50a is cleaned by the cleaning tool extending into the window 32a;

after the screws in the first connection hole 15a and the second connection hole 16a are removed by a screwdriver or the like, the bracket 30a is removed, so that the heater 50a is basically completely exposed, and the surface of the heater 50a can be deeply and completely cleaned by the cleaning tool.

Further figures 21 to 24 present schematic views of an aerosol-generating device 100b of yet another embodiment; in this implementation, the aerosol-generating device 100b is configured to be generally elongate, cylindrical in shape, having a length dimension of about 90-110 mm, and an outer diameter dimension of about 15-20 mm.

Further the aerosol-generating device 100b further comprises a proximal end 110b and a distal end 120b opposite along the length direction; and:

a first housing 10b proximate the distal end 120b;

the first housing 10b is also provided with a second housing 15b adjacent the proximal end 110 b;

an extractor 40b at the proximal end 110b for extracting the aerosol-generating article a; in this preferred implementation, the extractor 40b extracts the aerosol-generating article a by being removed directly from the second housing 10 b.

As further shown in fig. 22 and 23, the first housing 10b is also provided with a second housing 15b adjacent the proximal end 110 b; correspondingly, the extractor 40b includes an operating portion 410b having a ring shape, and a receiving portion 420b having a cylindrical shape located inside the operating portion 410 b. In implementation, the user can perform the extraction operation by applying a force to the operation portion 410b with a finger; and, the aerosol-generating article a is removably received within the receiving portion 420b by a receiving aperture 41b defined by the operating portion 410 b. 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 toward the proximal end 110b, and is thereby stably held on the second housing 15b; and the outer surface of the second housing 15b also serves to provide guidance in the user's extraction operation of the extractor 40 b.

As further shown in fig. 24, the receiving portion 420b has a supporting wall 421b for supporting the aerosol-generating article a; the supporting wall 421b is provided with a first hole 422b for the susceptor 50b to pass through into the receiving portion 420b for insertion into the aerosol-generating article a; the supporting wall 421b is also provided with a second aperture 423b for the entry of air into the aerosol-generating article a of the receiving portion 420b.

Further provided in the second housing 15b are:

a bracket 20b having a substantially tubular shape extending in a longitudinal direction of the second housing 15b; and the holder 20b is arranged substantially coaxially with the second casing 15b and is located inside the second casing 15b; the holder 20b defines a receiving space 210b therein in which, in use, the receiving portion 420b of the extractor 40b is received to form an operative condition of the heatable aerosol-generating article a within the receiving space 210 b;

a magnetic field generator, such as an induction coil 30b surrounding the support 20b, for generating a varying magnetic field;

a susceptor 50b configured to generate heat upon penetration by a varying magnetic field to heat the aerosol-generating article a; the susceptor 50b is preferably configured in the shape of an axially extending pin, needle or plate or the like at least partially in 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 210 b.

According further to fig. 24, the free front end of the susceptor 50b is located in the accommodation space 210b, the end opposite to the free front end 50b being held by the holder 70 b. Specifically, the fixed seat 70b includes a first fixed seat 71b and a second fixed seat 72b sequentially arranged from inside to outside in the radial direction of the susceptor 50 b; the first anchor 71b is preferably a ceramic having low thermal conductivity, such as zirconia, and the second anchor 72b is preferably an organic polymer having low thermal conductivity, such as PEEK.

In the design of the suction air flow, as further shown in fig. 21 to 24, the second housing 15b is provided with a first air inlet 151b; in a specific positional arrangement, the first air inlet 151b is located at a position where the second casing 15b is adjacent to the first casing 10b, and likewise adjacent to a portion where the operating portion 410b of the extractor 40b is engaged with the first casing 10 b. When assembled, the operating portion 410b, when retained in the second housing 15b, covers the first air inlet 151b and reveals the first air inlet 151b when the aerosol-generating article a is extracted by removal/movement or the like to an extraction position. In the operating position, the operating portion 410b of the extractor 40b has an engagement gap of about 2mm with the first casing 10b, with which the first air inlet 151b is opposite and in air-flow communication. The external air enters the first air inlet 151b from the gap engaged between the operating portion 410b and the first housing 10b during the suction.

The stand 20b also has an inner bottom wall 221b defining a receiving space 210 b; the inner bottom wall 221b is spaced from the holder 70b of the susceptor 50b by a distance or gap of about 1-3 mm, and the inner bottom wall 221b also has a second air opening 222b. In operation, the second port 222b is opposite the second hole 423b in the extractor 40 b.

Then, in the suction process, the external air enters the first air inlet 151b from the gap between the operating part 410b and the first housing 10b, as indicated by the arrow R2, flows from the first air inlet 151b to the second air port 222b along the gap between the bottom wall 221b and the fixed seat 70b, and finally enters the aerosol-generating article a from the second air port 222b through the second hole 423b of the extractor 40 b.

As can be seen, the gas flow path includes a gas inlet portion extending from the first gas inlet 151b to the second gas port 222b substantially in the radial direction of the susceptor 50 b; and a gas outlet portion extending lengthwise from the second gas port 222b to the proximal end 110 b. Basically, the gas inlet portion and the gas outlet portion are substantially vertical. Of course, in practice, the air outlet portion is passed through the receiving portion 420b of the receiving space 210b and/or the extractor 40 b.

Further in a more preferred embodiment, as shown in fig. 24, the second fixing seat 72b has a catching protrusion 721b extending to the first air inlet 151b, and the second housing 15b is held in the first air inlet 151b by the catching protrusion 721 b; when disassembly is required, the locking protrusion 721b can be pressed to disengage the first air inlet 151b, so that the second casing 15b can be disassembled or removed from the first casing 10 b.

It should be noted that the description and drawings of the present application illustrate preferred embodiments of the present application, but are not limited to the embodiments described in the present application, and further, those skilled in the art can make modifications or changes according to the above description, and all such modifications and changes should fall within the scope of the claims appended to the present application.
