Various devices and systems are available for heating or warming aerosolizable substances other than burning tobacco in conventional tobacco products.

Commonly used, risk-reduced or risk-modified devices are heated matrix aerosol-generating devices or heat-not-burn devices. Devices of this type generate an aerosol or vapor by heating an aerosol substrate, typically comprising moist tobacco leaf or other suitable solid aerosolizable, to a temperature typically in the range of 150°C to 350°C Material. Heating, but not igniting or scorching such an aerosol matrix, releases an aerosol that includes the components sought by the user but does not include the toxic carcinogenic by-products of combustion and burning. In addition, aerosols produced by heating tobacco or other aerosolizable materials generally do not include burnt or bitter tastes that may be unpleasant to the user from burning and burning, so the base does not require sugar and other Additives, sugars and additives are often added to such materials to make the smoke and/or vapor more palatable to the user.

In such devices, the substrate is typically contained substantially within the heating chamber, and the user typically needs to push a button after consumption to eject the substrate from the heating chamber for replacement with a new substrate. However, arranging buttons on the device may create voids on the housing of the aerosol-generating device that reduce access to the aerosol-generating device, and may complicate operation of the device by the user.

As used herein, the terms "aerosol-generating device," "vaporizer system," "inhaler," or "electronic cigarette" may include electronic cigarettes configured to deliver an aerosol to a user, including for Smoking aerosols. In the present invention, the illustrated embodiments of the aerosol generating system are illustrative.

Referring to the drawings and in particular to FIG. 1 , an electronic cigarette 1 for consuming a substrate is shown. The electronic cigarette 1 can be used as a substitute for conventional cigarettes. The electronic cigarette 1 has a generally elongated shape, including a cover 104 and a body 106, the cover serving as a device mouthpiece with an air inlet and/or outlet. The cover 104 is rotationally hinged to the body 106 . During or after the time the substrate 130 is heated to generate the aerosol, air is driven towards the mouthpiece (ie, the cover 104) to provide the aerosol to the user. In some embodiments, the air is driven by user inhalation. In other embodiments, the aerosol generating device 1 may comprise a pump for pumping air to the suction nozzle to provide the aerosol. The cover 104 has a closed position, which covers the heating chamber 107 and compresses and maintains the substrate 103 in the heating chamber 107 . The cover 104 also has an open position, where the opening 105 of the heating chamber 107 is exposed for insertion or removal of the substrate 103 . The main body 106 includes an ejection mechanism 101 (shown in diagonal lines), a heating or furnace chamber 107 (oriented vertically in the main body), a LiPo battery 1061, a PCBA 1062 with electronic components such as a CPU or controller, and A USB-C connector 1063 for charging the LiPo battery 1061 and/or transferring data to the electronic cigarette 1 . When the aerosol-generating substrate 103 is consumed, at least a portion of the substrate 103 is enclosed in the heating chamber 107, preferably, the majority of the substrate 103 is enclosed in the heating chamber 107, and most preferably , the entire substrate 103 is enclosed in the heating chamber 107 in such a way that when the lid 104 is closed, the substrate 103 is pressed by the lid 104 and maintained in a position where the substrate 103 can be substantially heated, while the ejection mechanism 101 is heated Press until it locks or snaps (discussed below). When the cover 104 presses the substrate 103 in the closed position, an aerosol is generated by the portion of the substrate 103 inserted into the heating chamber 107 .

The housing of the main body, as well as the cover, can generally be made of any rigid material, such as thermoplastic or metal (eg, aluminum). The insulating cladding contained between the housing and the heating chamber can be made, for example, of polyethylene terephthalate (PET), polybutylene terephthalate (PBT) or polyamide (PA) Made of other heat-resistant materials to prevent thermal deformation or melting. The heat-resistant material can be a super engineering plastic such as polyimide (PI), polyphenylene sulfide (PPS) or polyetheretherketone (PEEK). A portion of the ejection mechanism is made of insulating material, or the ejection mechanism may be coated with insulating material.

FIG. 1 shows a schematic perspective view of an aerosol-generating substrate 103 . Matrix 103 may, for example, include nicotine, tobacco, and/or aerosol formers. Tobacco can take the form of various materials such as cut tobacco, granulated tobacco, leaf tobacco and/or reconstituted tobacco. Suitable aerosol formers include: polyols such as sorbitol, glycerol, and glycols such as propylene glycol or triethylene glycol; non-polyols such as monohydric alcohols, acids such as lactic acid, and glycerol derivatives such as triethylene glycol. Acetate, triethylene glycol diacetate, triethyl citrate, glycerol or vegetable glycerol and other esters. In some embodiments, the aerosol generating agent may be glycerol, propylene glycol, or a mixture of glycerol and propylene glycol. The matrix 103 may also include at least one of a gelling agent, a binder, a stabilizer, and a humectant.

The matrix 103 is porous so that air can flow through the matrix 103 and collect the aerosol at this time. The matrix 103 may be, for example, foam, or wrapped strands or fibers. The substrate 103 may be formed into a stable shape by extrusion and/or rolling processes. The aerosol-generating substrate 103 may be shaped to provide one airflow channel, or in preferred embodiments, multiple airflow channels, as shown in FIG. 1 . These air flow channels may be aligned with the air flow channels of the aerosol generating device 1 in order to increase the air flow through the heating chamber 107 . Substrate 103 is exposed with a bare outer surface. Alternatively, the matrix 103 may include a breathable wrap covering at least a portion of the surface of the matrix 103 . The wrap may, for example, comprise paper and/or nonwoven fabrics.

In this embodiment, the substrate may have a generally flat cuboid shape or pod shape with dimensions of 18 x 12 x 1.2 mm, wherein the length, width and depth of the cuboid are each in the range of, for example, +/- 40% select within. Generally, in preferred embodiments, the length of the matrix is between 40 and 10 mm, preferably between 30 and 12 mm, more preferably between 25 and 14 mm, and most preferably between 25 and 14 mm. The optimum is between 22 and 15 mm. In preferred embodiments, the width of the substrate is between 30 and 6 mm, preferably between 25 and 8 mm, more preferably between 20 and 9 mm, and most preferably between 16 and 9 mm. In preferred embodiments, the height of the substrate is between 3 and 0.5 mm, preferably between 2 and 0.6 mm, more preferably between 1.8 and 0.8 mm, and most preferably between 1.6 and 0.9 mm.

The aerosol-generating substrate is preferably designed to be longer than or equal to the length of the heating chamber 107 in the longitudinal direction (shown as a straight dashed line in Figure 4a). In this case, when the cover is in the closed position, the part that is ejected from the device after insertion is accommodated in the hollow of the cover 104 (as shown in Figures 3a and 3b) and pressed by the cover . In other words, the heating chamber 107 has a generally rectangular parallelepiped shape corresponding to the shape of the substrate 103, with a size of 18 x 12 x 1.2 mm, with each of the length, width and depth of the rectangular parallelepiped being selected within a range of +/- 40% . The length of the heating chamber is preferably less than 18 mm, and the width and depth of the heating chamber 107 are preferably longer than 12 mm and 1.2 mm. More specifically, in a preferred embodiment, the length of the aerosol generating chamber 107 is between 40 and 9 mm, preferably between 30 and 11 mm, and more preferably between 25 and 13 mm. between, and most preferably, between 22 and 14 mm. In a preferred embodiment, the width of the chamber 107 is between 31 and 6 mm, preferably between 26 and 8 mm, more preferably between 21 and 9 mm, and most preferably is between 17 and 9 mm. In preferred embodiments, the depth of the chamber 107 is between 4 and 0.5 mm, preferably between 3 and 0.6 mm, more preferably between 2.8 and 0.8 mm, and most preferably is between 2 and 0.9 mm.

This means that the opening 105 of the heating chamber 107 is large enough to easily insert the substrate 103 into the heating chamber 107 . In other embodiments, the substrate 103 has a shorter length than the heating chamber 107 .

FIG. 2 shows a flow diagram of the process of insertion, consumption, and extraction of the substrate 103 in the aerosol-generating device 1 . Before using the device 1 and consuming the substrate 103, the user first opens the lid 104 of the device 1 with no substrate 201 in the device. The user then inserts 202 the matrix 103 into the opening 105 of the heating chamber 107 along the first axis along the longitudinal direction of the device. The substrate 103 needs to be pressed until the user feels a click from the substrate while the ejection mechanism transitions from the ejected state to the hold-locked state (discussed below) 203 . This means that when the substrate 103 reaches its travel limit, the bottom surface of the heating chamber 107 is locked in place (in its lower position), thereby substantially or completely lowering the consumable into the heating chamber 107 . The user closes the lid while the ejection mechanism transitions from the hold locked state to the hold unlocked state (discussed below) 204 . The user activates the device 205 and begins consuming the substrate 206 by pressing a button on the device. In an alternative embodiment, a sensor may be arranged in the device 1 to sense the closure of the lid and the presence of the substrate 103 in the device 1 and then automatically trigger heating of the substrate 103 . After the user completes consumption of substrate 103, the user simply opens lid 207. At least a portion of the substrate 103 emerges and ejects from the opening 105 of the heating chamber 107 as the ejection mechanism 101 transitions from the remaining unlocked state to the ejected state (discussed below). In one embodiment, a sensor is arranged to sense the opening of the cover 104 to stop the heating of the heating chamber 107 . Finally, the user dislodges the substrate 103 from the device 208.

Figures 2a-2d, 3a-3c and 4 illustrate specific configurations of the ejection mechanism.

The ejection mechanism 101 is connected at least indirectly to the heating chamber 107 and the cover 104 . The heating chamber 107 has two openings arranged on opposite sides of the heating chamber 107 along the insertion direction 108 of the substrate 103 . One of these two openings is the opening 105 for inserting and extracting the substrate 103 , and a portion of the ejection mechanism (ie, the support member) (discussed below) can be inserted into the opening 105 at the bottom end of the heating chamber 107 . in another opening. This portion of the ejection mechanism supports the substrate as the bottom, inner lower surface or floor of the heating chamber 107 as it heats the substrate 103 and protrudes into the heating chamber 107 in the ejected state. This surface can move vertically. This surface is ejected or protruded in the heating chamber 107 to such an extent that when the user wants to replace the substrate 103, at least a portion of the substrate 103 protrudes out of the heating chamber 107 so that the user can manually remove the substrate 103 Remove from device 1. Preferably, this surface protrudes upwards halfway through the heating chamber 107 . For example, if the length of the substrate 103 is 18 mm and the length of the heating chamber 107 is equal to the length of the substrate 103 (also 18 mm), the ejection mechanism may protrude into the heating chamber 103 a predetermined distance of 9 mm so that the substrate The 103 is ejected the same distance 9 mm from the chamber. With this arrangement, the user can easily pull out the substrate 103 by pinching the protruding portion of the substrate 103 , and the substrate 103 does not easily fall out of the heating chamber 107 . The ejection mechanism also has a portion that protrudes from the upper surface of the main body of the device 1 when the cover 104 is in the open position and the ejection mechanism is in the ejected state and in the locked state. The portion protruding from the upper surface of the main body is configured to trigger the ejection mechanism 101 to transition from the locked state to the unlocked state when the portion is squeezed by the cover 104 from the open position to the closed position.

In this embodiment, more specifically, the ejection mechanism 101 includes a support member 1014 (marked with a crossed line), springs 1013, 1065, and a snap or clamp member 1014 (marked with a diagonal line) having an upper Section 1017 (marked with dense slashes) and lower section 1018 (marked with loose slashes). Support member 1014 is configured to support substrate 103 . The snap or clip member 1014 is configured to snap or clip the support member 1014 to lock the bottom surface in the lower position by snapping the support member 1014 and a protrusion included in the snap or clip member 1014, or The substrate is substantially inserted into the heating chamber 107 at the lower limit for heating. At least one of the springs 1013 is configured to provide an ejection force to the ejection mechanism 101 , and more particularly the support member, to eject at least a portion of the substrate 103 out of the heating chamber 107 .

In a preferred embodiment, the support member 1014 includes an arm that supports the substrate 103, and a cover portion below the arm, the interior of the cover portion receiving at least a portion of the spring 1013 to ensure that the support member 1014 and the spring 1013 along the The first axis (shown as a straight dashed line in Figure 3a) moves together. The arm supports or forms at least a portion of the bottom surface of the heating chamber 107 . In an alternative embodiment, the arm is directly supported by the spring 1013 of the ejection mechanism 101 .

In the preferred embodiment, the snap member 1014 includes an upper portion 1017, and a lower portion 1018 that mechanically engages with another spring 1019 (shown in FIG. 5). The upper portion 1017 is slidingly engaged with the lower portion 1018 . The upper portion 1017 is preferably capable of protruding farther than the receiving opening 105 when the cover 104 is in the open position, and serves as a button 1064 to transition from the hold locked state to the hold unlocked condition. In the preferred embodiment shown in the drawings, the two protrusions 1064 of the snap member 1014 protrude from the opening 105, so that the cover 104 can press the snap member stably and evenly, so as to be more stable and have Better sealing performance. The lower portion 1018 includes protrusions of the snap member 1012 to snap and hold the support member 1014 in place. When the cover depresses the button 1064 of the upper portion 1017 (which slides down the lower portion 1018 or presses along a second axis (not shown)), the protrusions 1016 of the lower portion 1018 and the support member 1014 are implemented and released The snap of the protrusion 1015. The protrusions 1015 of the support member 1014 and the protrusions 1016 of the lower portion 1018 are also slidingly engaged. In order to prolong the life of the device with the constant ejection and insertion of the substrate 103, the ejection mechanism 101 comprises or preferably is made of a metallic material. Preferably, the lower portion 1018 and at least the protrusion of the arm are made of metal.

As shown in FIG. 5, the upper portion 1065 engages the torsion spring 1065 and another portion of the device 1 (preferably the lower portion 1018) to ensure that when the lid 104 is in the open position, the spring force is applied so that the upper portion 1017 The button 1064 protruding out of the housing of the main body of the device 1 is ready to be pressed by the cover 104 . In this embodiment, the cover 104 includes a protrusion configured to depress the button 1064 of the upper portion 1017 .

In the following, the different states of the ejection mechanism 101 in the device 1 are discussed with reference to Figures 2a to 2d, 3a to 3c and 4, more particularly the ejection state, the hold locked state and the hold unlocked state. Ejection state

The ejected state occurs when the cover 104 is opened and no substrate 103 is inserted, or when the cover 104 is opened and the substrate 103 is ejected from the opening 105 of the heating chamber 107 . In other words, when the user opens the cover (201, 207), the device 1 or the ejection mechanism 101 is in or switched to the ejection state.

As shown in Figures 3a, 4a and 4b, in the ejected state of the ejection mechanism 101, the cover 104 is in an open position and the ejection mechanism 101 is configured to receive the substrate 103, or to at least partially protrude the received substrate 103 out of the heating chamber 102 and the ejection mechanism 101 can be switched to remain locked.

More specifically, the user opens the cover 104 and the button 1064 located on the upper part of the upper part 1017 is released from the pressure from the protrusion 1041 of the cover 104 and from the main body of the device 1 from the opening adjacent to the receiving opening 105 highlighted in. The lower portion 1018 (slidingly engaged with the upper portion 1017 in the inclined plane) is also released to its initial position, where it is ready to be slid aside and can snap over the protrusion 1015 of the support member 1014. The lower portion 1017 is supported by a spring, or the lower portion 1017 itself is made of or includes a rigid material, so that the lower portion 1018 remains in the initial position, or rebounds or springs back to its original position when the pressure from the upper portion 1017 is relieved Location.

As shown in Figure 4b, the top surfaces of the arms of the support member 1014 support the substrate 103 in place such that at least a portion of the substrate 103 protrudes out of the opening 105 and the arms of the support member 1014 protrude at least partially into the upper portion of the heating chamber position or at the upper limit of the bottom surface. The support member 1014 is supported by the spring 1013 arranged below it, while the spring 1013 is in a relaxed state. The user removes the substrate 103 by grasping the protrusions of the substrate 103 . If the heating chamber 107 is empty (as shown in Fig. 4a), the user inserts the substrate into the heating chamber 107 along a first axis (shown as a straight dashed line in Fig. 4a). The top surface of the arm is pressed down with the substrate 103 until a lower position or limit is reached where the protrusions 1015 of the support member 1014 are snapped by the protrusions 1016 of the snap member 1014 (more specifically the underground portion 1018). As shown, both the protrusion 1015 of the support member 1014 and the lower surface of the upper portion 1017 have sloped surfaces that slidingly engage the top surface of the lower portion 1018 . With this configuration, the protrusions 1016 of the snap member 1012 can hold the ejection mechanism 101 in a retained locked state by snapping the protrusions 1015 of the arms, or release the protrusions 1015 of the arms to apply the ejection force. stay locked

In Figures 3b and 4c, the ejector is in the hold-locked state. The lid 1041 is in its open position, and the substrate 103 is substantially contained in the heating chamber 107, ready to be consumed.

More specifically, as shown in the enlarged view in the dashed circle of Fig. 4c, after the substrate 103 is pressed down by the user and is substantially contained in the heating chamber 107, the protrusions 1015 of the support member 1014 and the lower portion 1018 of the The planar surfaces of the protrusions 1016 snap or snap to each other. In other words, the protrusions 1015 of the arms partially engage the protrusions 1016 of the snap member in a sliding manner such that when the user pushes the substrate 103 into the chamber, the protrusions 1016 of the snap member can be caught by the protrusions of the arm 1015 is slidably pressed along a second axis (not shown) until the protrusions 1016 of the support member are snapped by the protrusions 1015 of the snap member to hold the ejection mechanism 101 in the retained locked state. The spring 1013 supporting the support member 1014 is in a compressed state. The upper part springs back and the button 1064 emerges from the opening of the housing of the device 1 by the support of another spring, which is a torsion spring 1065 as shown in FIG. 5 . keep it unlocked

In Figures 3c and 4d, the ejector is held unlocked. To consume the substrate 103, the user rotates the lid 104 to its closed position, and the substrate 103 is substantially contained in the heating chamber 107 and pressed by the lid 104 to be heated and consumed.

More specifically, as shown in the enlarged view in the dashed circle of Figure 4d, the lower portion 1018 is pressed out of the snap position by the upper portion 1017 (not shown) due to pressure from the cover 1041. The protrusions 1016 of the lower portion 1018 do not snap or catch the protrusions 1015 of the support member 1014 while remaining unlocked. In other words, the upper portion 1017 is configured to press the lower portion 1018 along a second axis (not shown) by a sliding force when the lid 104 depresses the upper portion 1017 from the open position to the closed position until the arm The protrusions 1015 of the support member 1012 are released or separated from the protrusions 1016 of the support member 1012 . When the support member 101 is released from the snap of the catch member 1014, the spring 1013 is still in its compressed state to generate an ejection force on the support member 1014 and the substrate 103, and the substrate 103 is substantially maintained under heating by the pressure from the cover 1041. in chamber 107. A securing mechanism (not shown) in the lid 1041 and/or the body of the device 1 is configured to maintain the lid 1041 in the closed position against the ejection force from the spring through the substrate 103, and the securing mechanism is preferably Is includes magnets or snap fasteners. With this securing mechanism, the cover 104 prevents the substrate 103 from being ejected by the ejection force and allows the suction period to begin.

After the consumption of the substrate 103 is complete, the user can open the lid 104 of the device 1 . The button 1064, and at least a portion of the substrate 103, are ejected from the body of the device, and the ejection mechanism transitions from the remaining unlocked state to the ejecting state, enabling the user to remove the substrate 103 from the heating chamber 107 by simply opening the lid 104 .
