Further,FIG.5toFIG.7show a schematic diagram of a vapor generation device100of a specific embodiment. In this embodiment, the vapor generation device100includes:a main housing10, where the main housing10mainly serves as a housing component of the vapor generation device100, and further defines a first space1100, a second space1200, and a third space1300inside the main housing10; and therefore, in an implementation, the main housing10generally has requirements of a shape and a size of the vapor generation device100described above; anda door cover20, located at a proximal end110of the main housing10and/or the vapor generation device100, and being configured to be movable relative to the main housing10in an implementation, where certainly, according to the preferred embodiment shown inFIG.5andFIG.6, movement of the door cover20relative to the main housing10is sliding in a width direction of the main housing10, as shown by the arrow R1inFIG.6; or in other variation implementations, movement of the door cover20relative to the main housing10may be in the form of rotation around a specific axis.

As shown inFIG.5toFIG.7, the door cover20is designed to move, so that the door cover20has an open position (the open position is the second position) and a closed position (the closed position is the first position). The heating assembly (not shown in the figure) is arranged in the third space1300of the main housing10. In other words, the door cover20covers the heating assembly at the first position, and exposes the heating assembly at the second position. The door cover20is configured to be linearly movable between the first position and the second position relative to the main housing10. For example, the door cover20is configured to be linearly movable between the first position and the second position in a width direction of the main housing10. A guide structure (not shown in the figure) may be arranged on the door cover20, to provide guidance when the door cover20moves between the first position and the second position.

When the door cover20is at the closed position, for example, as shown inFIG.5, the door cover20blocks or seals the third space1300. In this case, the vapor generation device100is locked and cannot be used; and when the door cover20is at the open position, for example, as shown inFIG.6andFIG.7, the third space1300is exposed, and then a user may receive an aerosol-generating product A into the vapor generation device100for inhaling, and clean the third space1300.

The main housing10has a length direction, the width direction, and a thickness direction, and has a proximal end and a distal end (namely, the proximal end110and the distal end120of the vapor generation device100) that are opposite to each other in the length direction; and the heating assembly is arranged close to the proximal end. When being configured at the first position, the door cover20further blocks the heating assembly (the first side and the second side are a front side and a rear side of the main housing10inFIG.6) from the proximal end of the main housing10, a first side of the main housing10in the thickness direction, and a second side of the main housing in the thickness direction10.

Further, as shown inFIG.5toFIG.7, a guide groove11is provided on the main housing10, and is configured to provide guidance for a movement process of the door cover20. Specifically, in a preferred implementation, the guide groove11is provided on a side surface of the main housing10in a thickness direction; and the guide groove11is configured as a slender groove extending in a width direction of the main housing10. During use, the door cover20at least partially extends into the guide groove11, thereby engaging with the guide groove11to form guide for a movement process; and positions of end portions at two ends of the guide groove11are used to limit the movement of the door cover20.

In the implementation shown in the figure, the guide groove11has a length approximately ranging from 30 mm to 40 mm.

For a shape or a structure of the door cover20, refer toFIG.8. The door cover20includes:a first blocking wall210, basically parallel to an upper side surface of the main housing10, where the first blocking wall210is located at a proximal end of the main housing10, and the third space1300is blocked or closed at a proximal end110when in a use state at the closed position; anda second blocking wall220and a third blocking wall230, extending in a length direction of the main housing10, where the second blocking wall220and the third blocking wall230are connected to the first blocking wall210at the proximal end110. The second blocking wall220and the third blocking wall230are separately arranged on two sides of the main housing10in a thickness direction, the second blocking wall220is located on a first side of the main housing10in the thickness direction, and the third blocking wall220is located on a second side of the main housing10in the thickness direction; and further, during use, the second blocking wall220and the third blocking wall230separately block or seal a heating assembly in a third space1300from two sides of the main housing10in a thickness direction.

Further, a first hook221is arranged at an end portion of the second blocking wall220facing away from the first blocking wall210, and/or a second hook231is arranged at an end portion of the third blocking wall230facing away from the first blocking wall210; and during use, the first hook221and/or the second hook231at least partially extend into the guide groove11, to provide guidance while remaining connected to the main housing10, thereby preventing the first hook221and/or the second hook231from protruding from the guide groove11and causing the door cover20to fall off from the main housing10.

In the preferred implementation shown inFIG.8, the first blocking wall210and/or the second blocking wall220and/or the third blocking wall230are in a shape of a rectangle. In a more preferred implementation, the first blocking wall210has a length size approximately ranging from 15 mm to 25 mm and a width size approximately ranging from 5 mm to 10 mm. In addition, the second blocking wall220and/or the third blocking wall230have a length size approximately ranging from 28 mm to 40 mm, and a width size approximately ranging from 15 mm to 25 mm.

In a more preferred implementation, the door cover20is made of a highly heat conductive material, such as a metal material, which is conducive to promoting heat dissipation of a heating assembly in the third space1300and evenly transferring heat to other parts.

Further, refer toFIG.6andFIG.7, the vapor generation device100includes:a receiving hole41, located at a proximal end110, where an aerosol-generating product A may be at least partially received in the vapor generation device100through the receiving hole41. The door cover20simultaneously covers the heating assembly and the receiving hole41at the first position, and exposes the heating assembly and the receiving hole41at the second position.

In the preferred implementation shown inFIG.10, the receiving hole41is defined by an extractor40, and the extractor40is configured to extract the aerosol-generating product from the vapor generation device100. Alternatively, in other variation implementations, when the vapor generation device100does not have the extractor40, the receiving hole41may be further defined by a main housing10or a bracket30, or the like.

In addition, refer toFIG.10, correspondingly, the vapor generation device100includes:a receiving cavity430, where at least a part of the aerosol-generating product A is removably received in the receiving cavity430; and the receiving cavity430is in communication with the receiving hole41.

In the preferred implementation shown inFIG.10, the receiving cavity430is also defined by the extractor40. Alternatively, in other variation implementations, when the vapor generation device100does not have the extractor40, the receiving cavity430may be further defined by a main housing10or a bracket30, or the like.

Further, refer toFIG.9andFIG.10, the heating assembly includes:a heater50, configured in a shape of a pin, a needle, a sheet, and the like, such as a shape of a needle shown inFIG.9; and when the aerosol-generating product A is received in the vapor generation device100, the heater50may be inserted into the aerosol-generating product A for heating. In some optional implementations, the pin-shaped or needle-shaped heater50has a length size approximately ranging from 12 mm to 19 mm and an outer diameter size approximately ranging from 2 mm to 5 mm. In some other optional implementations, the sheet-shaped heater50may have a length size approximately ranging from 12 mm to 19 mm, a width size approximately ranging from 3 mm to 6 mm, and a thickness size approximately ranging from 0.4 mm to 1 mm. Correspondingly, as shown inFIG.10, the heater50extends at least partially in the receiving cavity430, thereby being beneficial to being inserted into the aerosol-generating product A for heating.

In other variation embodiments, the heater50may be further configured in a shape of a cylinder; and during use, an internal space of the heater50defines to form the receiving cavity430for receiving the aerosol-generating product A and generating an aerosol by heating a periphery of the aerosol-generating product A.

In some optional implementations, the heater50is a resistance heater; or Alternatively, in some implementations, the heater50is a susceptor that is penetrated by a magnetic field and generates heat.

Further, refer toFIG.9andFIG.10, the vapor generation device100includes:a bracket30, configured to support the extractor40in an implementation. In addition, the bracket30is further configured to surround or block the heater50to protect the heater50. Specifically,on one hand, the bracket30is arranged in the third space1300in a detachable manner. When the extractor40is connected to the vapor generation device100, the extractor40is supported or kept by the bracket30. On the other hand, if the bracket30at least partially surrounds or blocks the heater50, the heater50may at least be prevented from being completely exposed in the third space1300, which is conducive to preventing the user from being in contact with or touching the heater50. The door cover20blocks the bracket30at the first position, to prevent the bracket30from being removed from the main housing10; and the door cover20exposes the bracket30and releases the blocking at the second position. In a preferred implementation, the bracket30generally has a shape of a square. In an implementation, specifically, the bracket30has a length size approximately ranging from 25 mm to 40 mm, a width size ranging from 15 mm to 25 mm, and a thickness size approximately ranging from 5 mm to 10 mm.

Further, refer toFIG.9andFIG.10, the extractor40includes:a receiving portion420in a shape of a cylinder, where an internal space of the receiving portion420is configured as a receiving cavity430configured to receive the aerosol-generating product A; andan operating portion410, where during use, the user operates the operating portion410to move or remove the extractor40and extract the aerosol-generating product A by operating the operating portion410with a finger, or the like. When the extractor40is assembled in the vapor generation device100, the operating portion410is connected to the main housing10, so that the extractor40is stably kept on the vapor generation device100. Certainly, in some implementations, the operating portion410may be directly or indirectly connected to the main housing10. Alternatively, in the preferred implementation shown inFIG.9andFIG.10, the operating portion410is fixed and kept in the vapor generation device100by abutting against and being connected to an upper end portion of the bracket30.

Further, in a more preferred implementation, the extractor40may be moved or removed relative to the main housing10, to present an operating position and an extraction position that are opposite to each other. Specifically,

FIG.11is a schematic diagram of an extractor40at an operating position according to an embodiment. When the extractor40is at the operating position, an aerosol-generating product A is received in a receiving portion420, and is supported by a supporting wall421of the receiving portion420; and the heater50at least partially penetrates into a receiving cavity430defined by the receiving portion420through the supporting wall421, thereby heating the aerosol-generating product A. The operating position is basically an operating position formed by the heater50being inserted into the aerosol-generating product A. At the operating position, the extractor40remains connected to a main housing10.

FIG.12is a schematic diagram of an extractor40at an extraction position according to an embodiment. At the extraction position, when an operating portion410performs operation, the extractor40is moved or removed in a length direction relative to a main housing10, and then an aerosol-generating product A is separated from a heater50under support of a supporting wall421and is removed. The extraction position is formed by separation between the aerosol-generating product A and the heater50. The door cover20may also blocks the extractor40at the first position, to prevent the extractor40from being configured from the operating position to the extraction position; and the door cover20at least partially exposes the extractor40and releases the blocking at the second position. Specifically, the door cover20blocks the operating portion410of the extractor40at the first position, and exposes the operating portion410at the second position.

In an optional implementation, the extractor40is also directly or indirectly connected to the main housing10at the extraction position, which is conducive to preventing the extractor40from being detached from the vapor generation device100. Alternatively, in still another optional implementation, the extractor40is not directly or indirectly connected to the main housing10at the extraction position, and then the extractor40is detached from the main housing10and/or the bracket30at the extraction position, thereby facilitating direct removal or detachment from the vapor generation device100.

In an optional implementation, the aerosol-generating product A has a length approximately ranging from 40 mm to 80 mm, and an outer diameter size approximately ranging from 4 mm to 8 mm.

In still another preferred implementation, the receiving portion420of the extractor40has a length approximately ranging from 15 mm to 40 mm; and the receiving portion420correspondingly has an inner diameter approximately ranging from 4 mm to 8 mm.

Further, refer toFIG.13, the extractor40further includes:a first hole422, located on the supporting wall421, where an inner diameter is basically adapted to the heater50and is slightly greater, to allow the heater50to pass through the first hole422and then to be inserted into the receiving portion420; and when adapted to a pin-shaped or needle-shaped heater50, for example, as shown inFIG.13, the first hole422is in a shape of a circle, and has an inner diameter approximately ranging from 3 mm to 6 mm; anda second hole423, located on the supporting wall421and configured to allow external air to enter the aerosol-generating product A through the second hole423in an inhaling process, as shown by the arrow R2inFIG.13. In an implementation, the second hole423has an inner diameter approximately ranging from 1 mm to 2 mm. In addition, a quantity of second holes423may be more than one, and the second holes423are provided around the first hole422.

Further, refer toFIG.9andFIG.10, a structure of the bracket30includes:a left side wall310and a right side wall320that are opposite to each other in a width direction, where during assembly, the left side wall310is a side wall adjacent to the first space1100, and is connected to the main housing10in a detachable manner such as a buckle; the right side wall320is at least partially exposed outside the vapor generation device100after assembly, and at least partially defines an outer surface of the vapor generation device100in the width direction;a lower end wall350is adjacent to the second space1200in a length direction, a third hole33is formed on the lower end wall350, and during assembly, the heater50penetrates the third hole33from below into the bracket30in the length direction; anda front side wall330and a rear side wall340are opposite to each other in a thickness direction, and a window32is arranged at a position close to the lower end wall350of the front side wall330and the rear side wall340. In an optional implementation, the front side wall330and the rear side wall340are not connected to or in contact with the lower end wall350. In an implementation, the window32is defined by a distance between the front side wall330and/or the rear side wall340and the lower end wall350.

In an implementation, the window32is directly in communication with the external air, and then the second hole423of the extractor40may be in communication with the external air through the window32; and in an inhaling process, the external air directly enters the second hole423through the window32, and then enters the receiving cavity430along with the aerosol generated by the aerosol-generating product A and is jointly inhaled by the user, as shown by the arrow R2inFIG.10.

Further, as shown inFIG.9,FIG.10, andFIG.14, a free front end of the heater50penetrates into the bracket30; and an end of the heater50facing away from the free front end is fixed in the main housing10. Further, according to the implementation shown in the figure, the end of the heater50facing away from the free front end is surrounded and fixed by a fixing base52.

In addition, the heater50has an exposed portion51exposed through the window32; and certainly, the exposed portion51has a length approximately ranging from 2 mm to 5 mm. The exposed portion51of the heater50is visible through the window32. Certainly, after assembly, the exposed portion51is defined by a size or a position of the window32. Specifically, in this implementation, the fixing base52is covered by the lower end wall350of the bracket30, and the exposed portion51of the heater50is completely defined by the bracket30; and specifically, the fixing base52is defined by a part of the heater50located between the front side wall330and/or the lower end wall350of the rear side wall340in the length direction. The door cover20exposes the window32at the second position, to enable cleaning of the heater50through the window32.

Certainly, the exposed portion51is close to an end of the fixing base52and/or the heater50. It may be learnt fromFIG.14that a distance d4between the exposed portion51of the heater50and the free front end is approximately 12 mm. The exposed portion51is away from the free front end, and it is difficult for a cleaning tool to directly clean the exposed portion51from the receiving hole41of the extractor40. Generally, in an implementation, a distance d4between the exposed portion51of the heater50and the free front end is greater than 8 mm.

In still another implementation, the window32has a proper area, and by inserting some cleaning tools into the window32, the exposed portion51of the heater50is cleaned during use. In some implementations, the cleaning tools are, for example, a small brush, a steel wire strip, a scraper, and the like.

In some preferred implementations, the window32needs to be of a proper area, to provide a necessary size for the cleaning tools to insert into, but also needs to prevent fingers of the user from being burned by the heater50.

In a preferred implementation, an area of the window32is an area greater than 10 mm2and an area of the window32is less than 100 mm2. In a more preferred implementation, an area of the window32is greater than 30 mm2and an area of the window32is less than 80 mm2.

In the preferred implementation shown inFIG.9andFIG.14, the window32is basically in a shape of a square. For example, the window32is in a shape of a strip in a width direction of the bracket30. In a more preferred implementation, a length size d1of the window32extending in the width direction of the bracket30approximately ranges from 10 mm to 20 mm; and a width size d2of the window32extending in a length direction of the bracket30approximately ranges from 3 mm to 6 mm.

In a specific implementation shown inFIG.14, the length size d1of the window32is 17 mm; and the width size d2of the window32is approximately 4.2 mm.

In addition, in still another optional implementation, at least one of the length size d1and the width size d2of the window32shall not be greater than 10 mm, which is conducive to preventing the fingers of the user from inserting. In a more preferred implementation, at least one of the length size d1and the width size d2of the window32shall not be greater than 6 mm.

Correspondingly, a length of the exposed portion51of the heater50basically ranges from 3 mm to 6 mm. In a preferred implementation, a length of the heater50penetrating into the receiving portion420of the extractor40approximately ranges from 10 mm to 18 mm. In a preferred implementation, a length of the exposed portion51of the heater50does not exceed ⅓ of a total length of the heater50.

Further, refer toFIG.9andFIG.10, to facilitate guide of the extractor40and the bracket30during assembly, movement, or removal; and the bracket30further has a first inner wall360and a second inner wall370. As shown in the figure, the first inner wall360and the second inner wall370are configured in a shape of an arc, and the first inner wall360and the second inner wall370are opposite to each other. In addition, the first inner wall360and the second inner wall370are in a shape of an arc that is curved outward in the width direction, and a guide accommodating space31is defined between the first inner wall360and the second inner wall370. A shape of the accommodating space31is basically the same as a shape of the receiving portion420of the extractor40, and a size volume of the accommodating space31is slightly greater than a volume of the receiving portion420. The first inner wall360and the second inner wall370provide guidance when the extractor40is stably assembled to the bracket30and during movement or removal.

Alternatively, in another variation implementation, when the vapor generation device100does not have components of the extractor40, the accommodating space31between the first inner wall360and the second inner wall370is configured as a receiving cavity430configured to receive the aerosol-generating product A.

In addition, as shown inFIG.5andFIG.6, the door cover20blocks or closes the window32at the closed position; and at the open position, the door cover20opens or reveals the window32a.

In the preferred implementation shown inFIG.9andFIG.10, there is a distance between the first inner wall360and the left side wall310of the bracket30, thereby forming a first heat insulation cavity34between the first inner wall360and the left side wall310of the bracket30; and there is a distance between the second inner wall70and the right side wall320of the bracket30, thereby forming a second heat insulation cavity35between the second inner wall70and the right side wall320of the bracket30.

In the implementation shown in the figure, the first heat insulation cavity34and/or the second heat insulation cavity35are empty and open, and are in communication with the external air, thereby forming heat insulation through low heat conduction of the air; the first heat insulation cavity34prevents heat of the heater50from being transferred outward in a radial direction to an electric core11in the first space1100; and/or the second heat insulation cavity35prevents the heat of the heater50from being transferred outward in a radial direction to the right side wall320.

In some variation implementations, the first heat insulation cavity34and/or the second heat insulation cavity35are closed cavities, and internal pressures of the first heat insulation cavity34and the second heat insulation cavity35may be configured to be lower than the external pressure. In other words, the first heat insulation cavity34and/or the second heat insulation cavity35have a vacuum degree; and this is conducive to preventing heat transfer.

Alternatively, in some other variation implementations, the first heat insulation cavity34and/or the second heat insulation cavity35are filled with some heat insulation materials, such as aerogel, porous polymer, porous polyurethane, foam cotton, and the like; and this is conducive to preventing heat transfer.

Further, refer toFIG.9andFIG.10, the receiving portion420of the extractor40is also at least partially exposed to the window32.

When the door cover20amoves relative to the main housing10ain a width direction, the limiting protrusion17ais configured to provide a limit at the open position and the closed position of the door cover20a. Certainly, in a more preferred implementation, the door cover20acovers or hides the limiting protrusion17aat any moving position. The limiting protrusion17ais not exposed to a surface of the vapor generation device100at any moving position of the door cover20a.

In addition, the vapor generation device100further includes:a bracket30a, at least partially defines a window32awith the main housing10a; a heater50a, at least partially exposed in the window32a; andan extractor40a, supported and kept by the bracket30a.

Further, when there is no need to open the window32afor the sake of inhaling, safety protection, and the like, the window32ais blocked or covered or closed by the blocking member60a. When the exposed portion of the heater50aexposed through the window32aneeds to be cleaned, or when connecting components such as the screw/bolt/screw in the second connecting hole16aneed to be disassembled, the window32amay be opened by moving or removing the blocking member60a.

Correspondingly, a third magnetic member45ais arranged on the extractor40a, and is configured to magnetically attract the first magnetic member36aat an operating position, thereby causing the extractor40ato be stably kept on the bracket60a.

Further, in the preferred implementation shown in the figure, after assembly, in the length direction, magnetic pole arrangement directions of the first magnetic member36a, the second magnetic member64a, and the second magnetic member45aare the same. For example, in the preferred embodiment shown in the figure, the first magnetic member36ahas a first magnetic pole, such as an N pole, toward a proximal end110a, and a second magnetic pole, such as an S pole, toward a distal end120a. In addition, the second magnetic member64aalso has a first magnetic pole, such as an N pole, toward the proximal end110a, and a second magnetic pole, such as an S pole, toward the distal end120a.

After assembly, when being kept in the second housing15b, the operating portion410bcovers the first air inlet151b, and may expose the first air inlet151bwhen the aerosol-generating product A is extracted by operations such as removal/movement to the extraction position. At the operating position, there is a joining gap of approximately 2 mm between the operating portion410bof the extractor40band the first housing10b, and the first air inlet151bis opposite to and in airflow communication with the gap. In an inhaling process, the external air enters the first air inlet151bthrough the joining gap between the operating portion410band the first housing10b.

The bracket20bfurther has an inner bottom wall221bdefining the accommodating space210b; and there is a distance or gap approximately ranging from 1 mm to 3 mm between the inner bottom wall221band the fixing base70bof the susceptor50b, and the inner bottom wall221bfurther has a second air port222b. In an implementation, the second air port222bis opposite to the second hole423bon the extractor40b.

During inhalation, as shown by the arrow R2in the figure, the external air enters the first air inlet151bthrough the joining gap between the operating portion410band the first housing10b, flows from the first air inlet151bin the radial direction to the second air port222bthrough the gap between the bottom wall221band the fixing base70b, and finally enters the aerosol-generating product A from the second air port222bthrough the second hole423bon the extractor40band is then inhaled.

It may be learnt from the figure that an airflow path includes an air inlet portion extending from the first air inlet151bto the second air port222bbasically in a radial direction of the susceptor50b; and an air outlet portion extending from the second air port222bin a length direction to the proximal end110b. Basically, the air inlet portion is basically vertical to the air outlet portion. Certainly, in an implementation, the air outlet portion passes through the accommodating space210band/or the receiving portion420bof the extractor40b.

Further, in a more preferred implementation, as shown inFIG.24, the second fixing base72bhas a latching protrusion721bextending into the first air inlet151b, and the second housing15bis kept by the latching protrusion721bin the first air inlet151b; and when disassembly is required, the latching protrusion721bmay be pressed to detach from the first air inlet151b, so that the second housing15bis disassembled or removed from the first housing10b.

Still another embodiment of this application further provides a vapor generation system, configured to heat an aerosol-generating product to generate an aerosol, where the vapor generation system includes a main housing; and a heating assembly and a door cover are arranged on the main housing. The heating assembly is configured to heat the aerosol-generating product; and the door cover is coupled to the main housing, and is configured to be moveable relative to the main housing to cover or expose at least two surfaces of the heating assembly.
