[0013] L1 / L2 = 0.12.

[0014] As an optional technical solution for an aerosol generation system, the aerosol generation device includes a receiving chamber and a power chamber. The receiving chamber is used to receive the aerosol generation product. The driving component includes a driving member and a transmission member. At least a portion of the transmission member is located in the power chamber. The transmission member is connected to or abuts against the aerosol generation product and is drively connected to the output end of the driving member so as to move synchronously with the output end of the driving member, thereby driving the aerosol generation product to move relative to the heating element.

[0015] As an optional technical solution for an aerosol generation system, a guide channel is connected between the containment chamber and the power chamber, and at least a portion of the transmission component is located in the guide channel.

[0016] As an optional technical solution for the aerosol generation system, the drive assembly further includes a seal that provides a seal between the inner wall of the transmission member and the guide channel to isolate the receiving chamber and the power chamber.

[0020] This utility model has at least the following beneficial effects:

[0021] This invention provides an aerosol generation system, comprising an aerosol generation article and an aerosol generation device for housing at least a portion of the aerosol generation article. The aerosol generation device includes a heating element and a driving assembly. The heating element heats the aerosol generation article to generate aerosols; the driving assembly drives one of the heating element or the aerosol generation article to move relative to the other along a housing direction. One of the heating element and the aerosol generation article has a heating channel, and the other can move within the heating channel.

The extension length of the heating section is L1, and the extension length of the aerosol generation matrix section is L2, where 0.08 ≤ L1 / L2 ≤ 0.35. The aforementioned size limitation results in a shorter heating section relative to the aerosol generation matrix section. This allows heat to be concentrated in a localized area of ​​the aerosol generation matrix section while maintaining the same heating power, enabling the temperature in that localized area to rise rapidly and reducing the user's waiting time.

[0035] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0036] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0037] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

[0038] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0039] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0040] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0041] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0042] like Figures 1 to 6As shown, this embodiment provides an aerosol generation system, including an aerosol generation article 1000 and an aerosol generation device for containing at least a portion of the aerosol generation article 1000. The aerosol generation device includes a heating element 300 and a driving assembly 200. In this embodiment, the heating element 300 is used to heat the aerosol generating article 1000 to generate an aerosol; the driving component 200 is used to drive one of the heating element 300 or the aerosol generating article 1000 to move relative to the other along the housing direction; wherein, one of the heating element 300 and the aerosol generating article 1000 has a heating channel 310, and the other can move within the heating channel 310; the aerosol generating article 1000 includes an aerosol generating matrix section 1300 extending along the housing direction, and the heating element 300 includes a heating section extending along the housing direction and heating the aerosol generating matrix section 1300; the extension length of the heating section is L1, the extension length of the aerosol generating matrix section 1300 is L2, and 0.08≤L1 / L2≤0.35. In this embodiment, the aerosol generating device can be an electronic cigarette. The aforementioned dimensional constraints significantly shorten the length of the heating element 300. That is, the heating section is shorter than the aerosol generating matrix section 1300. This allows the heating element 300 to maintain the same power while improving its heating efficiency. It can concentrate heat in a local area of ​​the aerosol generating matrix section 1300, thereby quickly preheating the aerosol generating matrix section 1300, shortening the heating and waiting time, and enabling it to generate aerosol more quickly for smokers to inhale, thus improving the user experience.

[0043] For example, L1 / L2 = 0.3. Yet another example, L1 / L2 = 0.2. Still another example, L1 / L2 = 0.12. In other embodiments, the ratio of L1 / L2 may also be other values ​​between 0.08 and 0.35, not limited to the above embodiments.

[0044] To facilitate the containment of the aerosol generating article 1000, the aerosol generating apparatus includes a receiving chamber 110 for containing the aerosol generating article 1000, and a suction nozzle 400 communicating with the receiving chamber 110. The suction nozzle 400 defines an outlet 410 for aerosol to escape from the aerosol generating apparatus. The aerosol generating article 1000 is... Figure 2 When the tobacco block is in the form of a medium-sized tobacco block, the entire tobacco block can be an aerosol generation matrix. Thus, the part between the upper and lower ends of the tobacco block can be used as the aerosol generation matrix section 1300. After removing the mouthpiece 400, the tobacco block can be placed into the receiving chamber 110 or removed from the receiving chamber 110.

[0045] Specifically, the aerosol generating device includes a main body 100, a receiving chamber 110 disposed within the main body 100, and a suction nozzle 400 removably connected to the main body 100. When the suction nozzle 400 is connected to the main body 100, the suction nozzle 400 blocks the receiving chamber 110; when the suction nozzle 400 is removed from the main body 100, the receiving chamber 110 is exposed.

[0046] To prevent the fumes generated by the aerosol generating product 1000 from affecting the drive component 210, in some embodiments, the aerosol generating device includes a receiving chamber 110 and a power chamber 120. The receiving chamber 110 is used to receive the aerosol generating product 1000. The drive component 200 includes a drive component 210 and a transmission component 220. At least a portion of the transmission component 220 is located in the power chamber 120. The transmission component 220 is connected to or abuts against the aerosol generating product 1000 and is drively connected to the output end of the drive component 210 so as to move synchronously with the output end of the drive component 210, thereby driving the aerosol generating product 1000 to move relative to the heating component 300. This arrangement allows the aerosol generating product 1000 to be driven by the transmission component 220, thereby causing the aerosol generating product 1000 to move relative to the heating component 300, so that the heating component 300 heats different parts of the aerosol generating product 1000.

[0047] A guide channel 130 connects the receiving chamber 110 and the power chamber 120, and at least a portion of the transmission member 220 is located in the guide channel 130. The guide channel 130 provides guidance for the movement of the transmission member 220, preventing the transmission member 220 from swaying or deviating during movement.

[0048] The drive assembly 200 also includes a seal 230, which provides a seal between the inner walls of the drive member 220 and the guide channel 130 to isolate the receiving chamber 110 and the power chamber 120. This method ensures the connection between the drive member 210 and the drive member 220 while separating and isolating the receiving chamber 110 and the power chamber 120 through the seal 230, preventing smoke from entering the power chamber 120.

[0049] The sealing element 230 is annular and is fitted around the outer periphery of the transmission element 220, moving synchronously with it. The outer periphery of the sealing element 230 is in contact with the inner wall of the guide channel 130 and can move relative to it. The transmission element 220 is a rod-shaped structure.

[0050] During the movement of the seal 230, the gap between the sealing transmission member 220 and the sidewall of the guide channel 130 is maintained at all times. Furthermore, during the movement, the seal can scrape against oil stains on the sidewall of the guide channel 130 and carry the oil stains into the receiving chamber 110 for easy subsequent cleaning. To ensure synchronous movement of the seal 230 and the transmission member 220, the outer periphery of the transmission member 220 is provided with an annular groove, in which the seal 230 is located. In other embodiments, the seal 230 and the transmission member 220 are bonded together.

[0051] In some embodiments, the drive assembly 200 further includes a lead screw 240 and a movable member 250. The lead screw 240 is drivenly connected to the output end of the motor, and the movable member 250 has a threaded hole in which the lead screw 240 is threadedly fitted. The movable member 250 is connected to the transmission member 220 to drive the transmission member 220 to move synchronously. The lead screw 240 is rotatably mounted on the main body 100 and drivenly connected to the output end of the motor. The movable member 250 is slidably mounted on the main body 100 along the axial direction of the aerosol generating article 1000. The cooperation of the lead screw 240 and the movable member 250 allows for precise control of the moving distance of the movable member 250, thereby precisely controlling the moving distance of the transmission member 220, and consequently, precisely controlling the area of ​​the aerosol generating article 1000 heated by the heating member 300. In other embodiments, the drive member 210 can also be an electric actuator. The electric actuator can be directly connected to the transmission member 220, simplifying the structure and facilitating assembly and maintenance.

[0052] The movable component 250 and the main body 100 are slidably engaged via a sliding channel and a sliding rod 260. The sliding channel is located on one of the movable component 250 and the main body 100, and the sliding rod 260 is located on the other. Specifically, the movable component 250 has a sliding channel, and both ends of the sliding rod 260 are fixed to the main body 100 and pass through the sliding channel. The axis of the sliding channel and the axis of the threaded hole are arranged parallel to each other.

[0053] In some embodiments, of the transmission member 220 and the moving member 250, one is provided with a insertion groove 221 and the other with a insertion pin 251, the insertion pin 251 being inserted into the insertion groove 221. The axial direction of the insertion groove 221 is set at an angle to the moving direction of the transmission member 220. Specifically, the transmission member 220 includes a transmission body and a transmission seat disposed at the lower end of the transmission body; wherein, the insertion groove 221 is disposed in the transmission seat. The axial direction of the insertion groove 221 is perpendicular to the moving direction of the transmission member 220. Further, the outer diameter of the transmission seat is larger than the inner diameter of the guide channel 130. This arrangement allows the transmission member 220 to be limited during movement by means of the transmission seat.

[0054] In other embodiments, the transmission component 220 can be driven by magnetic force. Specifically, both the moving component 250 and the transmission component 220 are magnetic and can attract each other. The moving component 250 moves, driving the transmission component 220 to move as well. The movement of the moving component 250 can refer to the lead screw 240 driving method in the above embodiments. This method avoids the need for a channel between the receiving chamber 110 and the power chamber 120, further improving the mutual isolation between them.

[0055] When the aerosol-generated product 1000 is a block-shaped smoke block, regarding the position of the heating channel 310, in this embodiment, the heating channel 310 is disposed within the heating element 300, and the smoke block can pass through the heating channel 310. At the start of inhalation, the smoke block is in the initial position (refer to...). Figure 5 (As shown), then the heating element 300 is energized and heated, the smoke block generates an aerosol, and as the smoke block is consumed, it gradually moves upward to its final position (see reference). Figure 2 (As shown).

[0056] In some embodiments, the aerosol generating article 1000 includes a housing, an aerosol generating matrix section 1300 disposed within the housing, and a driving assembly 200 for driving the aerosol generating matrix section 1300 to move relative to the heating element 300 within the housing. Exemplarily, the driving assembly 200 is connected to the aerosol generating matrix section 1300 to drive the aerosol generating matrix section 1300 to move relative to the heating element 300.

[0057] Combination Figure 6 As shown, in some embodiments, the aerosol generating article 1000 resembles a traditional cigarette and further includes a cooling section 1200 and a filtering section 1100, namely, the filtering section 1100, the cooling section 1200, and the aerosol generating matrix section 1300, respectively. In this embodiment, there is no need to provide a mouthpiece 400; the aerosol generating article 1000 is simply inserted into the receiving chamber 110, and inhalation is achieved through the filtering section 1100.

[0058] In other embodiments, the heating element 300 may also be a heating needle, configured to be inserted into the aerosol generating article 1000 for heating. The heating needle includes a needle body and a heating portion disposed on the needle body, wherein the length of the heating portion along the axial direction of the heating needle is less than the length of the needle body. The length of the heating portion along the axial direction of the heating needle is H1, and the length of the aerosol generating matrix section 1300 in the aerosol generating article 1000 is H2, and 0.08 ≤ H1 / H2 ≤ 0.35.

[0059] When heating the smoke block with a heating needle, the smoke block has an axial through hole to allow the heating needle to be inserted into it. This facilitates movement of the smoke block relative to the heating needle and reduces friction between the smoke block and the heating needle. The through hole can be located at the exact center of the smoke block or off-center. It should be noted that the through hole is a heating channel 310 located within the smoke block.

[0060] Regarding the structure of the heating element, in the first embodiment of this invention, the heating element is implemented through resistance or electromagnetic induction. Specifically, heating in different areas is achieved by adjusting the distribution of resistance on the needle body. The needle body can also be made of a conductive material, and its resistance value is lower than that of the heating element.

[0061] In the second embodiment of this invention, an insulating layer is applied to the parts of the needle body that do not require heating to prevent current from passing through these parts, thereby concentrating the current in the uninsulated heating parts and achieving heating in those parts.

[0062] In the third embodiment of this invention, the heating needle uses microwave heating. An antenna that generates microwaves is wound around the section of the needle body that needs to be heated to form a heating element. Other sections that do not need to be heated are not equipped with antennas, thereby enabling localized heating of the heating needle.

[0063] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
