Description

Technical Field

[0001] This application relates to the field of aerosol generation technology, specifically to a heating non-combustible device. Background Technology

[0002] The heating chamber of the heated non-combustible device contains replaceable heated non-combustible products. The heating element within the chamber heats these products to generate an aerosol that can be inhaled by the user. After a period of use, the heated non-combustible products need to be replaced. Because heated non-combustible devices typically generate temperatures of 200°C to 300°C or even higher to heat the products, both the heated products and the heating chamber will be very hot. If a user comes into contact with the high-temperature heating chamber, they may suffer burns. Utility Model Content

[0003] This application provides a heat-not-burning device, the main purpose of which is to provide a heat-not-burning device with delayed opening to solve the problem of burns.

[0004] This application aims to provide a heating non-combustible device, comprising:

[0005] The outer casing includes a movable housing and a cover;

[0006] A heating assembly is fixed inside the box. The heating assembly has a heating chamber for accommodating non-combustible products. The cover is used to cover the heating chamber and provides an aerosol outflow channel communicating with the heating chamber.

[0007] A thermotropic deformable element, which is in thermally conductive contact with the heating assembly to sense the temperature within the heating cavity through heat transfer, the thermotropic deformable element having thermal deformation characteristics, exhibiting a first shape at a first deformation temperature and a second shape at a second deformation temperature; and

[0008] A limiting component, at least a portion of which is movably disposed within the box body, is used to cooperate with the cover to limit the opening and closing state of the cover;

[0009] In the first shape, the portion of the thermo-deformable element facing away from the heating component abuts against the limiting component to restrict the movement of the cover relative to the box body and keep the cover in a closed state.

[0010] When the thermo-deformable element is in the second shape, the limiting component can move relative to the box body to open the cover.

[0011] In some embodiments, the limiting component includes a lock body, a lock tongue, and an elastic reset member; one end of the lock body is movably placed inside the housing, a mounting hole is provided on the side wall of the housing, and the other end of the lock body passes through the mounting hole and is placed outside the housing;

[0012] The latch is conventionally connected to the lock body. The latch is used to lock with the cover body under the action of the lock body to restrict the closing of the cover body, or to unlock with the cover body to allow the cover body to open.

[0013] The thermo-deformable element restricts the movement of the lock body in the first shape, and releases the restriction on the lock body in the second shape;

[0014] The elastic reset member is used to apply an elastic force to the lock body to drive the bolt toward the cover body, so as to maintain the bolt and the cover body locked after the thermo-deformation member releases the restriction on the lock body.

[0015] In some embodiments, the cover can be rotatably disposed relative to the box body about a first rotation axis perpendicular to the axis of the heating cavity. A first torsion spring is sleeved on the first rotation axis to drive the cover to rotate relative to the box body and expose the heating cavity. The locking tongue can lock with the cover body after the cover body covers the heating cavity, thereby maintaining the deformation of the first torsion spring.

[0016] In some embodiments, the cover can be rotatably disposed relative to the box body about a second rotation axis parallel to the axis of the heating cavity. A second torsion spring is sleeved on the second rotation axis to drive the cover to rotate relative to the box body and expose the heating cavity. The locking tongue can lock with the cover body after the cover body covers the heating cavity, thereby maintaining the deformation of the second torsion spring.

[0017] In some embodiments, the cover can be slidably connected relative to the box body; the locking tongue can lock with the cover after the cover covers the heating cavity, preventing the relative sliding of the cover and the box body.

[0018] In some embodiments, the first shape of the thermo-deformable element is curved, and the curvature of the second shape of the thermo-deformable element is less than the curvature of the first shape.

[0019] In some embodiments, the thermo-deformable element is provided with a support member. The thermo-deformable element is divided into a first segment and a second segment. The first segment is located between the heating component and the support member, and the second segment is located between the support member and the side wall of the box body. The first segment is used to transfer the heat of the heating component to the second segment, and the second segment is used to cooperate with the limiting component to limit the opening and closing state of the cover body.

[0020] In some embodiments, the housing further includes a nozzle assembly fixed to the cover, the nozzle assembly defining at least a portion of the aerosol outflow channel, the cover having a closed state and an open state relative to the housing, wherein when the cover is in the closed state, the heating cavity is covered by the cover, and when the cover is in the open state, the heating cavity is exposed.

[0021] In some embodiments, the nozzle assembly includes a nozzle tube, and an air inlet is provided on the side wall of the nozzle tube for external gas to enter.

[0022] In some embodiments, the suction tube has a first air intake channel inside its wall; the heating assembly includes a heating cup, a second air intake channel is provided on the side wall of the heating cup, an air delivery hole is provided at the end of the second air intake channel away from the first air intake channel, the heating cup has a heating cavity inside, and the air intake hole, the first air intake channel, the second air intake channel, the air delivery hole and the heating cavity are interconnected.

[0023] According to the heat-not-burning device in the above embodiments, the thermotropic deformation element senses the temperature inside the heating chamber through heat transfer. When the temperature sensed by the thermotropic deformation element reaches the first deformation temperature, the thermotropic deformation element takes on a first shape to abut against the limiting component, thereby restricting the movement of the lid relative to the box and keeping the lid in a closed state. When the temperature sensed by the thermotropic deformation element reaches the second deformation temperature, the thermotropic deformation element takes on a second shape, and the limiting component moves relative to the box to open the lid. By cooperating with the thermotropic deformation element and the limiting component, a heat-not-burning device with a delayed opening function is provided, effectively solving the problem of burns when opening the lid directly and improving the safety of using the heat-not-burning device.

[0045] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0046] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0047] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0048] Heated non-combustible devices use a heating element to heat a heated product placed in a heating chamber via a hot airflow. This heats the product, causing it to generate an edible aerosol. The heated non-combustible product typically consists only of a matrix, usually formed by die-casting a mixture of tobacco powder or other plant powders with a certain proportion of polyols, flavorings, and binders. The heated non-combustible product is usually porous. Upon heating, the tobacco powder or plant powders, polyols, and flavorings volatilize, generating aerosols that cause the product to collapse, resulting in a reduction in its overall volume. When replacing a heated non-combustible product after heating is complete, the high temperature and volume reduction during removal make it highly susceptible to falling and causing burns to the user.

[0049] To address the aforementioned problems, this application provides a heat-not-burning device. A thermotropic deformable element deforms into a first shape when it senses the temperature of the heating chamber is at its deformation temperature via heat transfer. In this first shape, it abuts against a limiting component to keep the lid closed. When the thermotropic deformable element senses the temperature of the heating chamber is lower than the deformation temperature via heat transfer, it deforms into a second shape. In this second shape, the limiting component moves relative to the housing to open the lid. In the open state, the heating chamber is exposed, and the heat-not-burning product can be removed by inverting the device or using a tool. Through the cooperation of the thermotropic deformable element and the limiting component, a delayed lid opening function can be achieved, effectively solving the problem of burns caused by direct lid opening and improving safety.

[0050] See Figures 1-3 As shown, the heated non-combustible device provided in this application includes a housing 10, a heating component 20, a temperature-induced deformation component 40, and a limiting component 50.

[0051] The outer casing 10 includes a box body 11 and a cover body 12 that are movably connected. The heating component 20 is fixed inside the box body 12. The heating component 20 is provided with a heating chamber 210, which is used to contain the heat-non-combustible product. The heating component 20 can heat the heat-non-combustible product in the heating chamber 210 in a non-combustible manner. Specifically, the heat-non-combustible product can be heated by hot air flow through oxygen heating or anaerobic heating to generate an aerosol.

[0052] It is understandable that the heating chamber 210 is located within the housing 11, such as... Figure 1As shown, the heating assembly 20 should also have an opening 2101, which communicates with the heating chamber 210 to allow the heat-resistant non-combustible product to be placed into or removed from the heating chamber 210. The opening 2101 should also be exposed on one side of the box body 11. The box body 11 and the cover 12 are connected in a movable manner. The cover 12 is movable relative to the box body 11. Specifically, the cover 12 is movably connected to one side of the box body 11, allowing it to move relative to that side. During this movement, the opening 2101 of the heating chamber 210 can be covered or opened. When the opening 2101 of the heating chamber 210 is open, the heat-resistant non-combustible product can be removed from or placed into the heating chamber 210.

[0053] In some embodiments, a mounting groove may be provided on one side of the housing 11 to install the heating assembly 20 in the mounting groove, and the opening 2101 of the heating cavity 210 shall be kept in communication with the external space of the housing 11 through the groove of the mounting groove.

[0054] The cover 12 also provides an aerosol outlet channel 310. When the cover 12 covers the opening 2101 of the heating chamber 210, the aerosol outlet channel 310 and the heating chamber 210 are kept in communication through the opening 2101, and aerosol can be output through the aerosol outlet channel 310.

[0055] In this embodiment, the outer shell 10 further includes a suction nozzle assembly 30, which is fixed to the cover 12 and defines at least a portion of the aerosol outflow channel 310. Specifically, the suction nozzle assembly 30 is provided with a suction nozzle channel throughout. After the cover 12 is closed onto one side of the box 11, an airflow channel is also provided between the cover 12 and the box 11. This airflow channel communicates with the suction nozzle channel in the suction nozzle assembly 30 and constitutes the aerosol outflow channel 310. In this application, the aerosol outflow channel 310 is formed throughout the suction nozzle assembly 30. The cover 12 has a closed state and an open state relative to the box 11. When the cover 12 is in the closed state, the heating chamber 210 is covered by the cover 12, and the aerosol outflow channel 310 communicates with the heating chamber 210. When the cover 12 is in the open state, the heating chamber 210 is exposed.

[0056] The thermo-deformable element 40 and the heating assembly 20 are in thermally conductive contact, and the thermo-deformable element 40 can sense the temperature inside the heating cavity 210 through heat transfer. The thermo-deformable element 40 has thermal deformation characteristics; in other words, the thermo-deformable element 40 can take on a first shape at a first deformation temperature and a second shape at a second deformation temperature.

[0057] It should be noted that the first deformation temperature is the temperature inside the heating cavity 210 sensed by the thermo-deformable component 40 through heat transfer. This deformation temperature can be considered high temperature, for example, 60℃-300℃. The second deformation temperature is the temperature inside the heating cavity 210 after it has naturally cooled down after the heating component 20 stops working when the cover 12 needs to be opened. For example, the second deformation temperature can be below 60℃. The thermo-deformable component 40 can be a memory metal with a two-way memory effect, such as a nickel-titanium alloy. It has a flat or basically flat shape at low temperatures close to room temperature, and its curvature and bending amplitude increase at higher temperatures.

[0058] At least a portion of the limiting component 50 is movably disposed within the housing 12. The limiting component 50 is used to cooperate with the cover 12 to restrict the opening and closing state of the cover 12. Specifically, the limiting component 50 can lock the connection between the cover 12 and the housing 11 when the cover 12 covers the heating cavity 210 on one side of the housing 11. The thermo-deformable element 40 that undergoes the first deformation can limit the limiting component 50 to prevent the limiting component 50 from releasing the lock between the cover 12 and the housing 11, so that the cover 12 is restricted to open and is in a closed state by the limiting component 50. Alternatively, the thermo-deformable element 40 that undergoes the second deformation can release the limiting component 50, so that the cover 12 can move relative to the housing 11. At this time, the cover 12 can be opened and is in an open state without being restricted by the limiting component 50.

[0059] In this embodiment, as Figure 2 When the thermo-deformable element 40 deforms into a first shape at the first deformation temperature, the portion of the thermo-deformable element 40 facing away from the heating assembly 20 abuts against the limiting assembly 50. The thermo-deformable element 40, having undergone the first shape change, can limit the movement of the limiting assembly 50, thereby keeping the cover 12 closed and thus covering the heating cavity 210. Figure 3 When the thermo-deformable component 40 is deformed into a second shape at the second deformation temperature, the thermo-deformable component 40 that has undergone the second shape change releases the restriction on the limiting component 50, specifically by disengaging from the limiting component 50. Then the limiting component 50 can move relative to the box body 11, thereby releasing the restriction on the cover 12, and allowing the cover 12 to be opened to the open state.

[0060] In the above embodiments, the temperature-induced deformation element 40 switches from the first deformation temperature to the second deformation temperature under the natural cooling of the heating chamber 210. This process delays the opening of the cover 12, so that the temperature of the heated non-combustible product drops to a temperature that avoids scalding the user.

[0061] See Figures 2-4As shown, the limiting assembly 50 includes a lock body 51, a latch 52, and an elastic reset member 53. One end of the lock body 51 is movably placed inside the housing 11. A mounting hole 111 is formed in the side wall of the housing 11, and the other end of the lock body 51 passes through the mounting hole 111 and is placed outside the housing 11. The latch 52 is kinetically connected to the lock body 51. The latch 52 is used to lock with the cover 12 under the action of the lock body 51 to limit the cover 12 to be closed in the closed state, or the latch 52 is used to unlock with the cover 12 under the action of the lock body 51 to open the cover 12 to the open state.

[0062] The latch 52 keeps the cover 12 in a closed state by locking it with the cover 12. When the latch 52 is unlocked from the cover 12, the cover 12 can be opened to the open state. In the first shape, the thermostatic deformation element 40 abuts against the lock body 51 to restrict the movement of the lock body 51 and keep the latch 52 locked to the cover 12. In the second shape, the thermostatic deformation element 40 can release the restriction on the lock body 51, and the lock body 51 can then move the latch 52 to release the lock from the cover 12.

[0063] In a specific embodiment, the lock body 51 is movably installed in the mounting hole 111 and can slide back and forth along the axis of the mounting hole 111 relative to the mounting hole 111. The thermo-deformable element 40 restricts the movement of the lock body 51 in the first shape and releases the restriction on the lock body 51 in the second shape, allowing the lock body 51 to move. The moving lock body 51 drives the bolt 52 to lock or unlock with the cover 12, thus opening the cover 12 from the closed state or opening the cover 12 to the open state.

[0064] When the lock body 51 is restricted from moving by the thermo-deformable element 40, the latch 52 remains locked to the cover 12, thus restricting the cover 12 from closing to the closed state of covering the heating cavity 210. When the lock body 51 is released from the thermo-deformable element 40, the movement of the lock body 51 causes the latch 52 to release from the locked state with the cover 12, allowing the cover 12 to open to expose the heating cavity 210.

[0065] The elastic reset member 53 is used to apply an elastic force to the lock body 51 to drive the lock tongue toward the cover body 12, so as to maintain the lock tongue 52 locked to the cover body 12 after the temperature-induced deformation member 40 releases the restriction on the lock body.

[0066] See Figures 5-8 As shown, the cover 12 can be rotated relative to the box 11 around a first rotation axis 121 perpendicular to the axis of the heating cavity 210. A first torsion spring 122 is sleeved on the first rotation axis 121 to drive the cover 12 to rotate relative to the box 11 and expose the heating cavity 210. The locking tongue 52 can lock with the cover 12 after the cover 12 covers the heating cavity 210, thus maintaining the deformation of the first torsion spring 122.

[0067] After the cover 12 covers the heating cavity 210 and locks with the latch 52, the first torsion spring 122 is elastically compressed and stores elastic potential energy. When the cover 12 is unlocked from the latch 52, the first torsion spring 122 releases the elastic potential energy, causing the cover 12 to rotate around the axis of the first rotation axis 121, and putting the cover 12 in the open state that exposes the heating cavity 210.

[0068] like Figure 7 and Figure 8 As shown, in some embodiments, a deceleration buffer 125 is provided between the box body 11 and the cover body 12. The deceleration buffer 125 can be a gas strut, with its two ends connected to the box body 11 and the cover body 12 respectively. The deceleration buffer 125 can limit the speed at which the cover body 12 rotates relative to the housing 11 around the axis of the first rotation axis 121, so that the cover body 12 opens slowly relative to the housing 11.

[0069] In this embodiment, the cover 12 can be opened at an angle of 45°-90° relative to the box 11 to expose the heating chamber 210. Of course, in other embodiments, the opening angle of the cover 12 relative to the box 11 will also be different depending on the location of the heating chamber 210.

[0070] See Figures 9-12 As shown, the cover 12 is rotatable relative to the box 11 about a second rotation axis 123 parallel to the axis of the heating cavity 210. A second torsion spring 124 is sleeved on the second rotation axis 123 to drive the cover 12 to rotate relative to the box 11 and expose the heating cavity 210. The locking tongue 52 can lock with the cover 12 after it covers the heating cavity 210, thus maintaining the deformation of the second torsion spring 124.

[0071] After the cover 12 covers the heating chamber 210 and locks the cover 12 with the latch 52, the second torsion spring 124 is elastically compressed and stores elastic potential energy. When the cover 12 is unlocked from the latch 52, the second torsion spring 124 releases the elastic potential energy, causing the cover 12 to rotate around the axis of the second rotation axis 123, and putting the cover 12 in the open state that exposes the heating chamber 210.

[0072] It should be noted that, Figures 9-12 When the cover 12 rotates relative to the box 11 about the axis of the second rotation axis 123, since the axis of the heating cavity 210 is in the height direction of the box 11, in this rotation mode, the cover 12 is equivalent to rotating in a plane parallel to one side of the box 11. Figures 5-8 When the cover 12 shown rotates relative to the box 11 about the axis of the first rotation axis 121, the cover 12 opens by flipping.

[0073] See Figure 13 and Figure 14As shown, the cover 12 can be slidably connected to the box 11, wherein the sliding direction is a plane parallel to one side of the box 11, and the locking tongue 52 can lock with the cover 12 after the cover 12 covers the heating cavity 210, preventing the relative sliding of the cover 12 and the box 11.

[0074] In this embodiment, preventing the cover 12 from sliding relative to the box 11 is limited by a thermo-deformable element 40 in a first shape, such as... Figure 13 and Figure 14 As shown, a first limiting part 126 is provided on the cover 12. When the cover 12 covers the heating cavity 210 and the thermo-deformable element 40 senses the temperature of the heating cavity 210 at the first deformation temperature and takes on a first shape, the thermo-deformable element 40 in the first shape abuts against the first limiting part 126, preventing the cover 12 from sliding relative to the box body 11, thus locking the latch 52 with the cover 12. When the thermo-deformable element 40 senses the temperature of the heating cavity 210 at the second deformation temperature, it takes on a second shape. The thermo-deformable element 40 in the second shape disengages from the first limiting part 126, thus unlocking the latch 52 from the cover 12. At this time, the cover 12 can slide relative to the box body 11 to be in the open state.

[0075] It should be noted that a driving structure can also be provided for the sliding of the cover 12 relative to the box 11. For example, a spring can be provided, and the elastic potential energy stored after the spring is compressed can drive the cover 12 to slide relative to the box 11.

[0076] See Figure 4 As shown, in some embodiments, the latch 52 is fixedly connected to the cover 12, and a hook 521 is provided on the latch 52. The lock body 51 placed inside the box 11 is provided with a locking hole 511 and a second limiting part 512. The locking hole 511 is located on the part of the lock body 51 placed inside the box 11. The hook 521 cooperates with the locking hole 511 to lock the lock body 51 and the latch 52. The second limiting part 512 is used to limit the lock body 51 from disengaging from the mounting hole 111 and plays a role in preventing the lock body 51 from disengaging.

[0077] Specifically, the lock body 51 can move within the mounting hole 111 to be in either a first or second position. In the first position, the cover 12 is in a state of covering the heating chamber 210, and the latch 521 of the bolt 52 can be locked into the locking hole 511 of the lock body 51. The first position of the lock body 51 is limited by the thermo-deformable element 40, which undergoes a first shape change, to keep the cover 12 in the covered state. When it is necessary to open the cover 12, the lock body 51 is moved to the second position, and the latch 521 of the bolt 52 can disengage from the locking hole 511 of the lock body 51. Furthermore, the thermo-deformable element 40, which undergoes a second shape change, releases the restriction on the lock body 41, allowing the cover 12 to be opened.

[0078] See Figure 2and Figure 3 As shown, the housing 11 has a mounting part 113 inside, and the lock body 51 is sleeved with the mounting part 113. The lock body 51 has a first stop part 513. The elastic reset member 53 is elastically compressed between the mounting part 113 and the first stop part 513. After the lock body 51 changes position relative to the housing 11, the compressed elastic reset member 53 can restore the lock body 51 to its initial position.

[0079] In this embodiment, the lock body 50 has a front end 50a and a rear end 50b. The front end 50a is placed outside the housing 11 for pressing operation. The rear end 50b passes through the mounting part 113 and is provided with a second stop part 514. The elastic reset member 53 is located between the mounting part 113 on the side away from the second stop part 514 and the first stop part 513.

[0080] See Figure 2 , Figure 3 , Figure 13 and Figure 14 As shown, the first shape of the temperature-induced deformation component 40 is curved (e.g., Figure 2 In this configuration, the end of the thermo-deformable member 40, which has a first curved shape, can abut against the limiting component 40 or the first limiting portion 126, and the curvature of the thermo-deformable member 40 in the second shape is less than the curvature of the first shape. For example, the second shape is a straight line.

[0081] In some embodiments, the second shape of the temperature-induced deformation element 40 can be considered to be curved, while the first shape is straight.

[0082] See also Figure 2 , Figure 3 , Figure 13 and Figure 14 As shown, the thermo-deformable component 40 is provided with a support member 41. The thermo-deformable component 40 is strip-shaped, column-shaped, or rod-shaped. The thermo-deformable component 40 is divided into a first segment 401 and a second segment 402. The first segment 401 is located between the heating component 20 and the support member 41, and the second segment 402 is located between the support member 41 and the side wall of the box body 11. The first segment 401 is used to transfer the heat from the heating component 20 to the second segment 402. The second segment 402 is used to cooperate with the limiting component 50 to present a first shape or a second shape at a first deformation temperature or a second deformation temperature, respectively, thereby limiting the opening and closing state of the cover 12.

[0083] See Figure 15As shown, the suction nozzle assembly 30 includes a suction nozzle tube 31, with an air inlet 311 on its side wall for external gas to enter. The inner cavity of the suction nozzle tube 31 forms an aerosol outflow channel 310, and a first air inlet channel 312 is provided inside the tube wall of the suction nozzle tube 31. The heating assembly 20 includes a heating cup 21, with a second air inlet channel 211 on its side wall. The inner cavity of the heating cup 21 forms a heating chamber 210. When the cover 12 covers the heating chamber 210, the first air inlet channel 312 communicates with the second air inlet channel 211. The end of the second air inlet channel 211 away from the first air inlet channel 312 has an air delivery hole 212 located on the inner wall of the heating cup 21. The air inlet 311, the first air inlet channel 312, the second air inlet channel 211, the air delivery hole 212, and the heating chamber 210 are interconnected. In actual use, the user draws air through the suction tube 31, while external air enters the heating chamber 210 through the air inlet 311, the first air inlet channel 312, the second air inlet channel 211, and the air delivery hole 212.

[0084] See also Figure 15 As shown, the heating assembly 20 also includes a heat exchange core 22, a heating chamber 23, and a gas collecting plate 24. The heat exchange core 22, the gas collecting plate 24, and the heating chamber 23 are fixed in sequence inside the heating cup 21 along the height direction of the heating cup 21. The heat exchange core 22 is located between the heating chamber 23 and the bottom of the heating cup 21. The heat exchange core 22 is used to heat the gas flowing into the heating cup 21 from the gas inlet 212. The heating chamber 23 defines a heating cavity 210.

[0085] Specifically, the heat exchange core 22 is provided with multiple heat exchange holes 221 through it, and the air collecting plate 24 is provided with multiple air collecting holes 241 through it. External air enters into each heat exchange hole 221 of the heat exchange core 22 through the air supply hole 212. The heat exchange core 22 can generate heat to heat the air flowing through the heat exchange holes 221. The heated airflow is then transported to the heating chamber 210 defined by the heating chamber 23 through the machine hole 241.

[0086] In some embodiments, an air-gathering block 213 is also provided at the air outlet 212, which can increase the flow rate of the external air entering through the air outlet 212.

[0087] See also Figure 15As shown, a reducing pipe 32 is also provided in the inner cavity of the suction tube 30, and an extension 33 is defined at the top end of the suction tube 31. The reducing pipe 32 forms a first mixing chamber 321, an acceleration chamber 322, and a second mixing chamber 323 in sequence along the axial direction of the suction tube 30. The first mixing chamber 321, the acceleration chamber 322, and the second mixing chamber 323 are arranged in sequence along the airflow outlet direction and are interconnected. Thus, the aerosol is output through the first mixing chamber 321, the acceleration chamber 322, and the second mixing chamber 323 in sequence. In this embodiment, a first one-way valve 25 is also provided on the cover 12, and a second one-way valve 26 is also provided between the air outlet 212 and the second air inlet channel 211. The first one-way valve 25 is located on the channel wall of the second air inlet channel 211 and is connected to the first mixing chamber 321, allowing a small portion of the air entering through the second air inlet channel 211 to enter the first mixing chamber 321 to cool the aerosol. The second one-way valve 26 allows air entering through the second air inlet channel 211 to flow unidirectionally through the air outlet 212 and supply the heat exchange outlet 221, preventing aerosol leakage. The acceleration chamber 322 is preferably a pipe with a radial dimension at least smaller than that of the first mixing chamber 321, which accelerates the aerosol output flow rate and reduces suction resistance. The second mixing chamber 323 buffers the aerosol accelerated by the acceleration chamber 322, enabling further cooling.

[0088] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
