[0002] This application relates to the technical field of atomization, and more particularly to aerosol generating devices. [Background technology]

[0003] Aerosol generating devices, such as electronic atomizers, are popular among many users due to their health and cost-effectiveness. Typically, aerosol generating devices utilize a heating assembly to heat an aerosol-generating substrate, generating an aerosol from the aerosol-generating substrate as the user inhales. However, when the heating assembly heats the aerosol-generating substrate, the heating assembly generates a large amount of heat. If the heating assembly cannot dissipate the heat, the heat will continually accumulate, potentially damaging the heating assembly and other components of the aerosol generating device and affecting the normal operation of the aerosol generating device.

[0045] Aerosol generating devices, such as electronic atomizers, are popular among many users due to their health and cost-effectiveness. Typically, aerosol generating devices utilize a heating assembly to heat an aerosol-generating substrate, generating an aerosol from the aerosol-generating substrate as the user inhales. However, when the heating assembly heats the aerosol-generating substrate, the heating assembly generates a large amount of heat. If the heating assembly cannot dissipate heat, the heat will continually accumulate, potentially damaging the heating assembly and other components of the aerosol generating device and affecting the normal operation of the aerosol generating device. To address this issue, the present application provides an aerosol generating device 100 (shown in FIG. 1 ).

[0046] 1 and 2 , an aerosol generating device 100 according to an embodiment of the present application includes a housing 10, a heating assembly 20, and a heat dissipation assembly 30. The housing 10 includes a side wall 11 and a bottom wall 13, and the side wall 11 and the bottom wall 13 of the housing 10 collectively define a storage cavity 15. The heating assembly 20 is housed within the storage cavity 15 and is configured to emit a laser to heat an aerosol-generating substrate 63. The heat dissipation assembly 30 is housed within the storage cavity 15 and includes a body member 31, which includes a mounting portion 311 and an abutting portion 313. The heating assembly 20 is attached to the mounting portion 311, and the abutting portion 313 is closer to the side wall 11 of the housing 10 than the mounting portion 311 so as to dissipate heat from the heating assembly 20.

[0047] The aerosol-generating substrate 63 is an element capable of generating an aerosol by the action of heat, ultrasound, mechanical vibration, or the like. In some embodiments, the aerosol-generating substrate 63 is an atomization substrate carrier filled with tobacco liquid. The tobacco liquid is a mixed liquid in which substances such as nicotine are dissolved, and the solute is a common organic solute and / or inorganic solute such as propylene glycol, vegetable glycerin, and pure water. When heated by the heating assembly 20, the tobacco liquid disperses into fine mixed droplets, which mix with air to form an aerosol. In other embodiments, the aerosol-generating substrate 63 is a leaf atomization substrate, which, when heated by the heating assembly 20, volatilizes fine solid particles, which mix with air to form an aerosol.

[0048] The heating assembly 20 is a structure capable of generating thermal energy or transferring thermal energy to another part. In some embodiments, the heating assembly 20 can directly convert other forms of energy, such as electrical energy, chemical energy, or solar energy, into thermal energy and transfer it to another part to be heated via thermal conduction. In other embodiments, the heating assembly 20 generates other forms of energy, such as electromagnetic waves, lasers, or thermal radiation, that can directly act on the surface of the part to be heated, thereby increasing the temperature of the area exposed to the electromagnetic waves, laser, or thermal radiation. For example, in the present embodiment, the heating assembly 20 emits a laser beam onto the aerosol-generating substrate 63, which irradiates and heats the aerosol-generating substrate 63, generating an aerosol. Heating the aerosol-generating substrate 63 using the laser tip 23 allows for rapid generation of aerosol from the aerosol-generating substrate 63, ensuring freshness of the aerosol every time a user inhales.

[0049] In the aerosol generating device 100 of the present application, the heating assembly 20 is connected to the mounting portion 311 of the main body member 31, and the abutment portion 313 is closer to the side wall 11 of the housing 10 than the mounting portion 311, thereby allowing the heat dissipation assembly 30 to conduct heat generated by the heating assembly 20 during operation to the housing 10 and dissipate heat from the heating assembly 20, preventing damage to the heating assembly 20 and other components of the aerosol generating device 100 due to accumulation of heat generated in the heating assembly 20 and ensuring normal operation of the aerosol generating device 100.

[0050] The aerosol generating device 100 will be further described below with reference to the drawings.

[0051] As shown in FIGS. 2 and 3 , in some embodiments, the aerosol generating device 100 may further include a cartridge assembly 40, a substrate assembly 60, and a drive assembly 80. The heating assembly 20, the heat dissipation assembly 30, the cartridge assembly 40, and the drive assembly 80 are all provided within the receiving cavity 15. At least a portion of the substrate assembly 60 is received in the cartridge assembly 40 and configured to support an aerosol-generating substrate 63. The heating assembly 20 is configured to emit a laser to heat the aerosol-generating substrate 63. The heat dissipation assembly 30 is configured to dissipate heat from the heating assembly 20. The drive assembly 80 is configured to drive and rotate the substrate assembly 60 relative to the cartridge assembly 40 so that the heating assembly 20 corresponds to different substrate portions 631 (shown in FIG. 5 ).

[0052] As shown in Figure 4, in some embodiments, the housing 10 may include a side wall 11 and a bottom wall 13, and the side wall 11 and the bottom wall 13 of the housing 10 together define a receiving cavity 15. In one embodiment, the housing 10 is made of a metal material such as aluminum alloy or stainless steel, which can improve the heat dissipation effect of the aerosol generating device 100 and ensure normal operation of the aerosol generating device 100. In another embodiment, the holder may be made of a plastic material such as PC or PCTG, which can reduce the weight of the housing 10 and further make the aerosol generating device 100 lighter.

[0053] In some embodiments, the heating assembly 20 includes a circuit board 21 and one or more laser chips 23. The circuit board 21 is provided in the heat dissipation assembly 30, and the one or more laser chips 23 are attached to the circuit board 21 and configured to emit lasers at the aerosol-generating substrate 63.

[0054] The circuit board 21 is electrically connected to the laser chip 23. The laser chip 23 emits a laser beam toward the aerosol-generating substrate 63, increasing the local temperature at the contact point between the laser and the aerosol-generating substrate 63, thereby generating aerosol for the user to inhale. In one embodiment, the laser chip 23 is permanently fixed to the circuit board 21, using a fixing method such as, but not limited to, welding, adhesive bonding, or an interference fit. In another embodiment, the laser chip 23 is removably attached to the circuit board 21, using a mating connection or a threaded connection, etc. Heating the aerosol-generating substrate 63 using the laser chip 23 can rapidly generate aerosol from the aerosol-generating substrate 63, ensuring freshness of the aerosol every time the user inhales. In another embodiment, the heating assembly 20 can heat the aerosol-generating substrate 63 using a rapid heating method such as plasma.

[0055] In one embodiment, only one laser chip 23 may be provided, i.e., one laser chip 23 heats the aerosol-generating substrate 63, thereby reducing manufacturing costs. In another embodiment, multiple laser chips 23 may be provided, i.e., multiple laser chips 23 jointly heat the aerosol-generating substrate 63, thereby improving aerosol generation efficiency, and even if some laser chips 23 are damaged, the other laser chips 23 can still normally heat the aerosol-generating substrate 63 to generate aerosol for the user to inhale, thereby ensuring the operational stability of the aerosol-generating device 100.

[0056] As shown in FIGS. 2, 3 and 5, in some embodiments, the aerosol-generating substrate 63 has a cylindrical structure, and the direction of laser emission is approximately perpendicular to the extension direction of the aerosol-generating substrate 63.

[0057] Specifically, the cylindrical aerosol-generating substrate 63 has multiple substrate portions 631, which are distributed along the circumferential direction of the cylindrical aerosol-generating substrate 63. When the aerosol-generating substrate 63 rotates, the heating assembly 20 can correspond to different substrate portions 631 of the aerosol-generating substrate 63. In one embodiment, the laser emission direction is perpendicular to the extension direction of the aerosol-generating substrate 63. In this case, the distance the laser travels to reach the corresponding substrate portion 631 is shortest, thereby improving the heating efficiency of the heating assembly 20 for the corresponding substrate portion 631. When the aerosol-generating device 100 is inhaled, the time required for aerosol generation from the aerosol-generating substrate 63 is reduced, achieving the effect of "inhaling at any time and stopping at any time," thereby improving the user's inhalation experience. In another embodiment, the laser emission direction and the extension direction of the aerosol-generating substrate 63 form a predetermined small included angle. For example, the predetermined small included angle is 30° or less. The predetermined small included angle increases the irradiation area of ​​the laser, and the aerosol-generating substrate 63 is heated to generate a sufficient amount of aerosol, thereby ensuring a good absorption feeling.

[0058] In some embodiments, the outer contour shape of the substrate portion 631 may be, but is not limited to, a rectangle or a circle. In one embodiment, the area and outer contour shape of the multiple substrate portions 631 of the aerosol-generating substrate 63 may all be the same. When the aerosol-generating substrate 63 rotates, the heating assembly 20 may correspond to different substrate portions 631. By providing multiple identical substrate portions 631, the aerosol-generating substrate 63 rotates at the same angle each time, simplifying the control program for the drive assembly 80 to drive and rotate the aerosol-generating substrate 63. In another embodiment, the area or outer contour shape of the multiple substrate portions 631 may be different. By providing multiple different substrate portions 631, the aerosol-generating device 100 can assign the heating assembly 20 to different substrate portions 631 according to the user's smoking habits (e.g., preferring to inhale a small amount of aerosol first, then a large amount of aerosol). This prevents the aerosol-generating substrate 63 from generating too much or too little aerosol when heated, ensuring a consistent smoking experience for the user.

[0059] 2 , in some embodiments, the heat dissipation assembly 30 may include a body member 31 and an extension member 33. The body member 31 is housed within the housing cavity 15, and the heating assembly 20 is attached to the body member 31. The extension member 33 extends from a bottom of the body member 31 to and is connected to the bottom wall 13 of the housing 10, and the body member 31 and the extension member 33 are configured to conduct heat generated by the heating assembly 20 to the housing 10.

[0060] Specifically, the body member 31 and the extension member 33 may be made of a material that is resistant to high temperatures and has a fast heat conduction rate, such as, but not limited to, polyetheretherketone (PEEK) material, high-melting-point metal, or high-temperature-resistant ceramic. At least a portion of the body member 31 and the extension member 33 abuts against the inside of the side wall 11 of the housing 10, thereby allowing the circuit board 21 and the laser chip 23 to dissipate heat and prevent them from being overheated and damaged during operation, thereby ensuring the normal operation and safe use of the aerosol generating device 100.

[0061] In some embodiments, the main body member 31 may include a mounting portion 311 and an abutment portion 313, where the mounting portion 311 faces the side wall 11 of the housing 10, the heating assembly 20 is mounted to the mounting portion 311, and the abutment portion 313 abuts against the inside of the side wall 11 of the housing 10 and is configured to conduct and dissipate heat generated by the heating assembly 20 to the housing 10. Specifically, the mounting portion 311 includes a mounting side 3111, and the abutment portion 313 includes a first side 3131, a second side 3133, and a third side 3135, and the first side 3131 of the abutment portion 313 faces the mounting side 3111, and the second side 3133 of the abutment portion 313 faces the third side 3135 of the abutment portion 313, and the mounting side 3111, the second side 3133 of the abutment portion 313, the first side 3131 of the abutment portion 313, and the third side 3135 of the abutment portion 313 are connected in order.

[0062] The mounting portion 311 faces the side wall 11 of the housing 10, and the heating assembly 20 is mounted on the mounting side 3111, so that the laser emission direction of the heating assembly 20 faces the side wall 11 of the housing 10. Note that in some embodiments, when the heating assembly 20 and the main body member 31 are arranged side by side, i.e., when the laser emission direction of the heating assembly 20 faces the side wall 11 of the housing 10, the projection of the heating assembly 20 and the projection of the main body member 31 overlap in the laser emission direction, which increases the contact area between the heating assembly 20 and the main body member 31, thereby ensuring the heat dissipation effect of the main body member 31 on the heating assembly 20 and ensuring normal operation of the aerosol generating device 100.

[0063] As shown in FIGS. 2 and 5 , in some embodiments, the mounting portion 311 further includes a mounting groove 3113. The mounting groove 3113 is recessed from the mounting side 3111 toward the first side 3131 of the abutting portion 313, and the circuit board 21 and the laser chip 23 are disposed within the mounting groove 3113. By providing the mounting groove 3113, when the sidewalls of the circuit board 21 and / or the laser chip 23 contact the sidewalls of the mounting groove 3113, the contact area between the body member 31 and the heating assembly 20 is increased, improving the heat dissipation effect. Furthermore, by providing the mounting groove 3113, the focal length of the laser chip 23 can be easily adjusted, improving the heating efficiency of the aerosol-generating substrate 63 by the laser chip 23. Furthermore, by providing the mounting groove 3113, the space occupied by the heating assembly 20 can be reduced, thereby enabling the aerosol generating device 100 to be miniaturized. In another embodiment, the circuit board 21 and the laser chip 23 may be directly attached to the mounting side 3111 (i.e., the mounting groove 3113 is not provided), thereby simplifying the processing process of the main body member 31 and improving the production efficiency of the heat dissipation assembly 30. Note that in some embodiments, the circuit board 21 may be attached in the mounting groove 3113 by adhesive, welding, engagement, or other attachment methods.

[0064] In some embodiments, the extension member 33 includes a first subsection 331 and a second subsection 333. The first subsection 331 extends from the bottom of the body member 31 toward the side where the heating assembly 20 is located, and the second subsection 333 extends from the bottom of the first subsection 331 toward the bottom wall 13 of the housing 10, such that the first subsection 331, the second subsection 333, and the body member 31 form a Z-shaped structure.

[0065] Specifically, the second subsection 333 extends from the bottom of the first subsection 331 until it abuts the bottom wall 13 of the housing 10, and the bottom of the second subsection 333 is connected to the bottom wall 13 of the housing 10. When projected toward the bottom wall 13 of the housing 10, the projection of the body member 31 and the projection of the second subsection 333 do not overlap, or only partially overlap, so that the first subsection 331, the second subsection 333 and the body jointly form a Z-shaped structure. The Z-shaped structure ensures that the main body member 31 and the extension member 33 have more mounting positions, such as the top of the main body member 31, the bottom of the main body member 31, the side of the main body member 31, the top of the first sub-section 331, and the side of the second sub-section 333, which facilitates rational utilization of the internal space of the aerosol generating device 100, reduces interference between each component, and achieves compactness, while increasing the contact area between the main body member 31 and the extension member 33 and the housing 10, improving the heat dissipation effect and ensuring the normal operation of the aerosol generating device 100.

[0066] In some embodiments, the second subsection 333 includes a first side 3331 and a second side 3333 facing each other. The first side 3331 of the second subsection 333 is the side away from the body member 31, and the second side 3333 of the second subsection 333 is the side closer to the body member 31. The aerosol generating device 100 further includes a motherboard 101, which is attached to the first side 3331 of the second subsection 333. The motherboard 101 can control the activation and deactivation of the heating assembly 20, the heating power of the heating assembly 20, etc.

[0067] In some embodiments, the aerosol generating device 100 further includes a power supply 103, which is located on the second side 3333 of the second subsection 333 and is electrically connected to the motherboard 101. The power supply 103 is configured to supply power to the motherboard 101, the heating assembly 20, and other functional assemblies 105. The power supply 103 and the motherboard 101 are located on the first side 3331 of the second subsection 333 and the second side 3333 of the second subsection 333, respectively, thereby avoiding interference between the power supply 103 and the motherboard 101, between the power supply 103 and other components, and between the motherboard 101 and other components, reducing the volume occupied by the power supply 103 and the motherboard 101, and achieving a compact aerosol generating device 100. In some embodiments, the aerosol generating device 100 may further include a charging port 104 attached to the motherboard 101 and exposed from the side wall 11 of the housing 10, thereby allowing a user to charge the power supply 103.

[0068] 2 and 6 , in some embodiments, the first side 3131 of the abutment portion 313 is recessed toward the mounting side 3111 to form a receiving groove 3137. The aerosol generating device 100 may further include a functional assembly 105, which is mounted in the receiving groove 3137. The functional assembly 105 includes at least one of a button 1051 and a light-emitting element 1053.

[0069] The button 1051 and the light-emitting element 1053 are both electrically connected to the motherboard 101. In some embodiments, the button 1051 is configured so that when a user presses the button 1051, the aerosol generating device 100 is started, and when the user presses the button 1051 again, the aerosol generating device 100 is stopped. The power source 103 also supplies power to the light-emitting element 1053, which provides notifications and instructions by changing its light intensity or color when the aerosol generating device 100 is started, stopped, charged, etc. The provision of the receiving groove 3137 reduces the space occupied by the functional assembly 105, thereby realizing a miniaturized aerosol generating device 100, while increasing the contact area between the functional assembly 105 and the main body member 31, thereby improving the heat dissipation effect of the main body member 31 on the functional assembly 105.

[0070] 5 , in some embodiments, the second side 3133 of the abutting portion 313 or the third side 3135 of the abutting portion 313 is recessed in a direction away from the side wall 11 of the housing 10 to form a fixing groove 3139, which communicates with the mounting groove 3137. The functional assembly 105 further includes a flexible circuit board 1055. The flexible circuit board 1055 is disposed in the fixing groove 3139 and connected to the functional assembly 105.

[0071] One end of the flexible circuit board 1055 is electrically connected to the functional assembly 105 (button 1051, light-emitting element 1053), and the other end is electrically connected to the motherboard 101. The provision of the fixing groove 3139 allows the flexible circuit board 1055 to be accommodated, improving the effect of the abutment part 313 in restricting and concealing the flexible circuit board 1055, preventing the flexible circuit board 1055 from shifting or bending during operation of the aerosol generating device 100, which would cause the flexible circuit board 1055 and the functional assembly 105 to become disconnected, ensuring normal operation of the aerosol generating device 100. At the same time, the contact area between the flexible circuit board 1055 and the main body member 31 is increased, improving the heat dissipation effect of the flexible circuit board 1055 from the main body member 31.

[0072] In some embodiments, the main body member 31 and the extension member 33 may both be attached to the accommodating cavity 15 by a connection method such as adhesive bonding, welding, engagement, or screw connection, thereby preventing the main body member 31 or the extension member 33 from vibrating (shaking) during operation of the aerosol generating device 100, which would cause noise in the aerosol generating device 100 or deviation in the laser direction of the laser chip 23. Thus, the main body member 31 and the extension member 33 are both connected to the housing 10, which ensures the stability of the main body member 31 and the extension member 33 and avoids noise generation, while ensuring the heating efficiency of the laser chip 23.

[0073] In one embodiment, the heat dissipation assembly 30 may further include a thermally conductive member (not shown). The thermally conductive member is disposed between the housing 10 and the body member 31 and configured to conduct heat from the body member 31 to the housing 10 for heat dissipation. In some embodiments, the thermally conductive member may be, but is not limited to, thermally conductive silicone grease, thermally dissipative silicone grease, thermally conductive tape, thermally conductive film, etc. Specifically, the thermally conductive member may be disposed between the body member 31 and the housing 10, thereby increasing the rate at which heat from the body member 31 is conducted to the housing 10 and improving heat dissipation efficiency. Alternatively, the thermally conductive member may be disposed between the heating assembly 20 and the body member 31, thereby ensuring that heat generated from the heating assembly 20 is rapidly conducted to the body member 31, improving the heat dissipation effect of the body member 31 on the heating assembly 20, and further ensuring normal operation of the aerosol generating device 100. In another embodiment, a heat conducting member is provided between the housing 10 and the extension member 33, and is configured to conduct heat from the extension member 33 to the housing 10. The type of the heat conducting member is almost the same as the heat conducting member in the above embodiment, and therefore, the description thereof will be omitted here.

[0074] 2, 3, 5, and 6, in some embodiments, the cartridge assembly 40 may include a support base 41, a cartridge cylinder 43, and a connection base 45. The support base 41 is attached to the first subsection 331 and / or the mounting side 3111. The cartridge cylinder 43 is attached to the side of the support base 41 away from the bottom wall 13 of the housing 10, and at least a portion of the substrate assembly 60 is housed within the cartridge cylinder 43, and the aerosol-generating substrate 63 is placed thereon. The cartridge cylinder 43 is provided with a light-transmitting region 431, which corresponds to the laser chip 23 of the heating assembly 20.

[0075] In some embodiments, the light-transmitting region 431 may be a light-transmitting solid region, i.e., the light-transmitting region 431 may be made of a light-transmitting material such as glass or resin. When the aerosol-generating substrate 63 rotates, the substrate portion 631 to be heated corresponds to the light-transmitting region 431, thereby ensuring that the laser from the heating assembly 20 passes through the light-transmitting region 431 and heats the corresponding substrate portion 631, thereby reducing laser loss along the propagation path. In one embodiment, the cartridge cylinder 43 further includes a light-opaque region 432 made of a non-light-transmitting material, thereby preventing the laser from irradiating other substrate portions 631 and ensuring the amount of aerosol generated during the next puff. In another embodiment, the entire cartridge cylinder 43 may be made of a light-transmitting material, thereby ensuring normal laser transmission while allowing the user to monitor the remaining amount of aerosol-generating substrate 63 and the aerosol generation status through the cartridge cylinder 43.

[0076] When the cartridge cylinder 43 includes a light-transmitting region 431 and a light-opaque region 432, in one example, the light-transmitting region 431 and the light-opaque region 432 may be integrally formed, thereby ensuring the sealing effect of the cartridge cylinder 43, preventing leakage of the aerosol generated when the aerosol-generating substrate 63 is heated, and ensuring the comfortable sucking sensation provided to the user; in another example, the light-transmitting region 431 and the light-opaque region 432 may be formed separately, thereby making it easy to remove and replace or clean the light-transmitting region 431 if the light-transmitting effect of the light-transmitting region 431 is reduced, for example, if the light-transmitting region 431 is dirty or worn or damaged, thereby ensuring the transmittance of the laser and further ensuring the heating effect of the aerosol-generating substrate 63 by the laser.

[0077] In some embodiments, the cartridge cylinder 43 includes a peripheral wall 433, one or more mounting brackets 435, and one or more limit bases 437. The peripheral wall 433 includes a first end 4331 and a second end 4333 opposite each other. The one or more mounting brackets 435 extend from the first end 4331 of the peripheral wall 433 toward the body member 31, and the mounting brackets 435 are configured to connect the peripheral wall 433 to the body member 31. The one or more limit bases 437 extend from the second end 4333 of the peripheral wall 433 toward the body member 31, and a portion of the limit base 437 is inserted into the body member 31, and the one or more limit bases 437 are connected to the support base 41.

[0078] The heating assembly 20 is provided between the peripheral wall 433 and the main body member 31, and the light-transmitting region 431 is provided in the peripheral wall 433, so that the laser from the heating assembly 20 can pass through the peripheral wall 433 and heat the substrate portion 631 to be heated. The provision of the mounting bracket 435 and the limit base 437 improves the mounting stability of the cartridge cylinder 43 and prevents noise caused by shaking during use of the aerosol generating device 100. Furthermore, by inserting a portion of the limit base 437 into the main body member 31, the stability of the cartridge cylinder 43 is further improved and noise generation can be prevented, while facilitating positioning of the cartridge cylinder 43 during mounting, thereby improving the assembly speed of the aerosol generating device 100. In addition, in some embodiments, the mounting bracket 435 and the main body member 31, and the limit base 437 and the support base 41 can be connected using a mounting method such as a screw connection or engagement, which makes it easier to assemble the aerosol generating device 100 and improves production efficiency, and also makes it easier to remove the faulty device for maintenance or replacement in the event of a malfunction in the cartridge assembly 40 or the internal device of the cartridge assembly 40.

[0079] In some embodiments, the cartridge cylinder 43 may be made of a metal material such as aluminum alloy or stainless steel, which prevents damage to the cartridge cylinder 43 due to heat generated during operation of the heating assembly 20 and ensures normal operation of the aerosol generating device 100. In another embodiment, the bracket may be made of a plastic material such as PC or PCTG, which reduces the weight of the cartridge assembly 40 and makes the aerosol generating device 100 lighter.

[0080] 2, 3, and 6, in some embodiments, the support base 41 includes a mounting plate 411 and a protrusion 413. The protrusion 413 extends from the mounting plate 411 toward the bottom wall 13 of the housing 10, and the protrusion 413 is connected to the first subsection 331 and / or the mounting side 3111. The aerosol generating device 100 further includes an air pressure sensor assembly 50, which is provided on the side of the protrusion 413 away from the mounting side 3111, and which detects whether the aerosol generating device 100 is being inhaled.

[0081] Specifically, the cartridge cylinder 43 and the protrusion 413 are located on opposite sides of the support plate 411. In one example, the protrusion 413 is connected to the first subsection 331, i.e., the protrusion 413 is supported on the top of the first subsection 331. The protrusion 413 may be connected by a mounting method such as welding, riveting, or adhesive bonding, thereby ensuring the stability of the support base 41. In another example, the protrusion 413 is connected to the mounting side 3111, and the protrusion 413 may be connected by a screw connection, engagement, adhesive bonding, welding, or other method, thereby also ensuring the stability of the support base 41. In yet another embodiment, the protrusion 413 is connected to the first subsection 331 and the mounting side 3111, and the connection between the protrusion 413 and the first subsection 331, and between the protrusion 413 and the mounting side 3111 may be made by welding, riveting, adhesive bonding, screw connection, engagement, etc., which further ensures the stability of the support base 41, increases the contact area between the support base 41 and the heat dissipation assembly 30, and improves the heat dissipation effect.

[0082] The air pressure sensor assembly 50 detects whether the aerosol generating device 100 is being inhaled. If the aerosol generating device 100 is being inhaled, the air pressure sensor assembly 50 can output a signal to the motherboard 101. Based on the signal, the motherboard 101 controls the heating assembly 20 to turn on so that the heating assembly 20 heats the corresponding substrate portion 631. If the aerosol generating device 100 is not being inhaled, the air pressure sensor assembly 50 can output a signal to the motherboard 101. Based on the signal, the motherboard 101 controls the heating assembly 20 to stop heating, and the above steps are repeated. Note that in some embodiments, the air pressure sensor assembly 50 can output a signal to the motherboard 101 based on the force of inhalation of the aerosol generating device 100, so that the motherboard 101 can control the heating assembly 20 to increase or decrease the heating power.

[0083] 2, 3, and 6, in some embodiments, the cartridge assembly 40 and the housing 10 collectively define the appliance airflow passage 110, and the air pressure sensor assembly 50 includes an electrical connector 51 and an air pressure sensor 53. The electrical connector 51 is provided on the side of the protrusion 413 away from the mounting side 3111. The air pressure sensor 53 is provided on the electrical connector 51, and the electrical connector 51 is provided with a through hole 511 that communicates with the appliance airflow passage 110. The air pressure sensor 53 covers the through hole 511, and the electrical connector 51 connects the air pressure sensor 53 to the motherboard 101. The air pressure sensor 53 is configured to determine whether the aerosol generating device 100 is being inhaled based on the air pressure in the appliance airflow passage 110.

[0084] 5 , when the user inhales, the air pressure in the appliance airflow passage 110 gradually decreases compared to the external air pressure, becoming negative. The air pressure sensor assembly 50 detects this change in air pressure in the appliance airflow passage 110 and determines that the aerosol-generating device 100 is inhaled. Accordingly, the air pressure sensor assembly 50 sends a signal to the motherboard 101, which controls the heating assembly 20 to activate and heat the corresponding substrate 631. When the user stops inhaling, external air enters the appliance airflow passage 110, and the air pressure in the appliance airflow passage 110 becomes equal to the external air pressure. The air pressure sensor assembly 50 detects that the air pressure in the appliance airflow passage 110 has returned to a positive pressure, thereby determining that the aerosol-generating device 100 is not inhaled. Accordingly, the air pressure sensor assembly 50 sends a signal to the motherboard 101, which controls the heating assembly 20 to stop heating.

[0085] In some embodiments, a sealing member (not shown) may be provided between the air pressure sensor 53 and the electrical connector 51, and / or between the electrical connector 51 and the instrument airflow passage 110. The provision of the sealing member can prevent leakage of gas within the instrument airflow passage 110, ensure the accuracy of the air pressure detection within the instrument airflow passage 110 by the air pressure sensor 53, and further ensure the normal operation of the aerosol generating device 100.

[0086] In some embodiments, the side wall 11 of the housing 10 is provided with an air intake hole 111 therethrough, and the cartridge assembly 40 further includes a connection base 45 attached to the support base 41. The support base 41 is provided with a first passage 415, and the connection base 45 is provided with a communication hole 453 that corresponds to and communicates with the second passage 451 and the air intake hole 111, and the second passage 451, the first passage 415, the communication hole 453, and the air intake hole 111 are sequentially communicated with each other to collectively form the appliance airflow passage 110.

[0087] External air can enter the aerosol generating device 100 through the air inlet 111, causing the air pressure in the appliance airflow passage 110 to equalize with the ambient air pressure. Specifically, when a user inhales, the air pressure in the appliance airflow passage 110 gradually decreases to a negative pressure. The air pressure sensor assembly 50 detects this change in air pressure in the appliance airflow passage 110 and sends a signal to the motherboard 101, which then controls the heating assembly 20 to activate and heat the corresponding substrate 631. When the user stops inhaling, external air enters the appliance airflow passage 110 through the air inlet 111, causing the air pressure in the appliance airflow passage 110 to equalize with the ambient air pressure. The air pressure sensor assembly 50 detects that the air pressure in the appliance airflow passage 110 has returned to a positive pressure, thereby determining that the aerosol generating device 100 is no longer inhaling. Accordingly, the air pressure sensor assembly 50 sends a signal to the motherboard 101, which then controls the heating assembly 20 to stop heating.

[0088] In some embodiments, the connection base 45 and the support base 41 of the cartridge assembly 40 are bonded together, i.e., the bottom of the connection base 45 and the top of the support base 41 are bonded together, thereby preventing gas leakage within the instrument airflow passage 110 and ensuring the accuracy of the air pressure detection within the instrument airflow passage 110 by the air pressure sensor assembly 50, while preventing the generated aerosols from escaping from the instrument airflow passage 110 and corroding the drive assembly 80 or other functional components, and ensuring the normal operation of the drive assembly 80 or other functional components.

[0089] 2 and 3 , in some embodiments, the substrate assembly 60 includes a support member 61 and an aerosol-generating substrate 63. At least a portion of the support member 61 is housed within the cartridge cylinder 43 of the cartridge assembly 40, the extension direction (longitudinal direction) of the support member 61 is substantially the same as the extension direction (longitudinal direction) of the body member 31, and the support member 61 rotates relative to the support base 41. The aerosol-generating substrate 63 is provided around the support member 61, and the aerosol-generating substrate 63 is housed within the cartridge cylinder 43. When the support member 61 rotates, the aerosol-generating substrate 63 rotates together with the support member 61.

[0090] 5, the support member 61 may be made of a high-temperature resistant material such as, but not limited to, a polyetheretherketone (PEEK) material, a high-melting point metal, or a high-temperature resistant ceramic. The aerosol-generating substrate 63 is provided around the support member 61 and corresponds to the heating assembly 20, and when the support member 61 rotates relative to the cartridge assembly 40, the aerosol-generating substrate 63 rotates together with the support member 61, thereby allowing the heating assembly 20 to correspond to a different substrate portion 631.

[0091] The extension direction of the support member 61 is approximately the same as the extension direction of the main body member 31, and the distance between one or more laser chips 23 and the aerosol-generating substrate 63 is approximately the same, thereby ensuring that the laser chips 23 uniformly heat different positions of the corresponding substrate portion 631, ensuring the aerosol generation efficiency, while reducing the space occupied by the substrate assembly 60 and the heat dissipation assembly 30, and realizing the miniaturization of the aerosol-generating device 100.

[0092] In some embodiments, the aerosol generating device 100 further includes a mouthpiece 70. The support member 61 includes a mounting portion 611, a support frame 613, and a connecting portion 615. The mouthpiece 70 penetrates the mounting portion 611, and at least a portion of the mounting portion 611 is located outside the cartridge cylinder 43. The support frame 613 is connected to the mounting portion 611, and is located within the cartridge cylinder 43. The aerosol-generating substrate 63 is provided surrounding the support frame 613, and the mounting portion 611 is in communication with the support frame 613. The connecting portion 615 is connected to the support frame 613, and is closer to the bottom wall 13 of the housing 10 than the support frame 613. The connecting portion 615 is detachably connected to the connecting base 45 of the cartridge assembly 40.

[0093] In some embodiments, the connection portion 615 and the connection base 45 are rotatably and hermetically connected, for example, a seal ring (not shown) is provided between the connection portion 615 and the connection base 45, which ensures normal rotation of the substrate assembly 60, allows the heating assembly 20 to be adapted to different substrate portions 631, ensures freshness of the aerosol generated from the aerosol-generating substrate 63 every time the user inhales, and improves the inhalation experience. In some embodiments, the connection base 45 may be made of a high-temperature resistant material such as polyetheretherketone (PEEK) or silicone rubber to prevent damage (e.g., deformation) of the connection base 45 due to heat and ensure normal operation of the aerosol generating device 100.

[0094] In some embodiments, the mouthpiece 70 includes a temperature-reducing section 71 and a filtration section 73, the temperature-reducing section 71 and the filtration section 73 are connected to each other, the temperature-reducing section 71 is provided to penetrate the mounting portion 611, the filtration section 73 is located at one end of the temperature-reducing section 71 away from the mounting portion 611, and at least a portion of the filtration section 73 is located outside the accommodating cavity 15.

[0095] In some embodiments, the temperature-reducing section 71 and the filtering section 73 are connected, allowing the user to inhale through the filtering section 73 and inhale the generated aerosol into their mouth. The temperature of the aerosol drops as it passes through the temperature-reducing section 71, preventing the user from inhaling hot aerosol. The filtering section 73 can filter out some impurities, preventing the user from inhaling impurities into their mouth and improving the inhalation experience for the user.

[0096] In some embodiments, the filtration section 73 includes a porous material such as, but not limited to, cotton or porous ceramic. The porous material facilitates the flow of gases and aerosols and has excellent adsorption capabilities, making it easy to adsorb impurities in the airflow and preventing the user from inhaling the impurities. In some embodiments, the temperature-reducing section 71 includes a polylactic acid material, which has excellent heat absorption capabilities to prevent the temperature of the aerosol from becoming excessively high after passing through the temperature-reducing section 71.

[0097] In some embodiments, the temperature-reducing section 71 and the mounting portion 611 may be attached in an interference fit manner, which ensures a tight seal between the mouthpiece 70 and the substrate assembly 60, prevents aerosol leakage, ensures the amount of aerosol inhaled by the user, and also ensures a comfortable inhalation experience.

[0098] As shown in Figures 2, 3 and 5, in some embodiments, the support member 61 forms multiple substrate airflow passages 120 with the aerosol-generating substrate 63, with each substrate portion 631 defining one substrate airflow passage 120, and the appliance airflow passage 110 of the aerosol-generating device 100 always communicating with the substrate airflow passage 120 defined by the substrate portion 631 that is currently heated.

[0099] Specifically, when a user inhales through the mouthpiece 70, the air pressure in the appliance airflow passage 110 gradually decreases compared to the outside air pressure, becoming negative pressure. The air pressure sensor assembly 50 can detect the change in air pressure in the appliance airflow passage 110 and determine that the aerosol generating device 100 is ready to be inhaled. The motherboard 101 controls the heating assembly 20 to heat the corresponding substrate part 631, generating an aerosol, and the generated aerosol is inhaled by the user through the substrate airflow passage 120. When the user stops inhaling, external air enters the appliance airflow passage 110 through the air inlet 111, and the air pressure in the appliance airflow passage 110 becomes equal to the outside air pressure. The air pressure sensor assembly 50 detects that the air pressure in the appliance airflow passage 110 has returned to a positive pressure, and determines that the aerosol generating device 100 is no longer inhaling. The motherboard 101 controls the heating assembly 20 to stop heating the corresponding substrate 631. At the same time, the motherboard 101 controls the drive assembly 80 to rotate the substrate assembly 60 so that the heating assembly 20 corresponds to the next substrate 631. This allows the aerosol generating device 100 to achieve the effect of "inhaling and stopping at any time," improving the user experience.

[0100] As shown in Figures 2 and 3, in some embodiments, the mounting portion 611 is provided with a through hole 6111, the support frame 613 is provided with a plurality of air flow passages 6131, and the connection portion 615 is provided with a plurality of insertion holes 6151, each air flow passage 6131 corresponds to one insertion hole 6151 and one through hole 6111, and each air flow passage 6131 forms one substrate air flow passage 120 together with the through hole 6111 and the corresponding insertion hole 6151.

[0101] 5 , the support frame 613, together with the aerosol-generating substrate 63, form a plurality of airflow passages 6131, with each different substrate portion 631 corresponding to one airflow passage 6131. ​​In one embodiment, the mounting portion 611 is provided with one through-hole 6111, which communicates with each of the plurality of airflow passages 6131. ​​The airflow passages 6131 and the insertion holes 6151 correspond one-to-one, with each airflow passage 6131, through-hole 6111, and corresponding insertion hole 6151 forming one substrate airflow passage 120. The mouthpiece 70 is provided to penetrate the mounting portion 611 and communicates with each of the plurality of through-holes 6111, i.e., the mouthpiece 70 communicates with each of the plurality of substrate airflow passages 120. Providing one through-hole 6111 simplifies the processing of the mounting portion 611 and improves the production efficiency of the support frame 613. In another embodiment, the mounting portion 611 is provided with a plurality of through-holes 6111 corresponding to different substrate portions 631, and the connecting portion 615 is provided with a plurality of insertion holes 6151 corresponding to the different substrate portions 631, so that the through-holes 6111, the airflow passages 6131, and the insertion holes 6151 correspond one-to-one to form one substrate airflow passage 120. The mouthpiece 70 penetrates the mounting portion 611 and communicates with each of the plurality of through-holes 6111, i.e., the mouthpiece 70 communicates with each of the plurality of substrate airflow passages 120. Providing multiple through-holes 6111 prevents the generated aerosol from entering other substrate airflow passages 120 through adjacent through-holes 6111, thereby ensuring the amount of aerosol inhaled by the user and ensuring a comfortable inhalation experience.

[0102] In some embodiments, a stopper member (not shown) is provided on the outside of the aerosol-generating substrate 63, and the stopper member prevents the aerosol generated from the aerosol-generating substrate 63 from flowing toward the laser chip 23. The stopper member may be made of tin paper or other light-transmitting material and attached to the outside of the aerosol-generating substrate 63. When the heating assembly 20 heats the corresponding substrate portion 631, heat passes through the stopper member to heat the corresponding substrate portion 631 and generate aerosol. The provision of the stopper member can prevent the generated aerosol from leaking from the substrate airflow passage 120 and corroding the heating assembly 20 and other components, ensuring normal operation of the aerosol-generating device 100 while also ensuring the amount of aerosol inhaled by the user and the inhalation sensation.

[0103] In some embodiments, the drive assembly 80 includes a drive member 81 and a connecting member 83. The drive member 81 is electrically connected to the motherboard 101.

[0104] Specifically, the output shaft 811 of the drive assembly 80 is connected to the connection portion 615 of the substrate assembly 60 via a connecting member 83, and the drive member 81 drives the substrate assembly 60 to rotate relative to the cartridge assembly 40 and further corresponds the heating assembly 20 to a different substrate portion 631. When the aerosol generation device 100 is inhaled, the heating assembly 20 heats the currently corresponding substrate portion 631. When the inhalation action on the aerosol generation device 100 is stopped, the output shaft 811 of the drive member 81 rotates to drive the substrate assembly 60 to rotate relative to the cartridge assembly 40 and corresponds the heating assembly 20 to the next substrate portion 631. In some embodiments, the drive member 81 may be a motor.

[0105] In some embodiments, one or more first passages 415 may be provided within the support base 41, and the one or more first passages 415 may all be provided at a distance from the connecting member 83, thereby preventing the aerosol generated from the aerosol-generating substrate 63 from corroding the connecting member 83 and ensuring normal operation of the drive assembly 80. In one example, the one or more first passages 415 may all be provided within the support base 41, and the first passages 415, the communication hole 453, and the air intake hole 111 communicate with each other to form the appliance airflow passage 110. Thus, providing the first passages 415 within the support base 41 further ensures the sealing of the appliance airflow passage 110 and ensures the accuracy of the air pressure sensor assembly 50 detecting the air pressure within the appliance airflow passage 110. In another example, the one or more first passages 415 may all be provided on the surface of the support base 41 facing the connection base 45, and the first passages 415, the communication holes 453, and the air intake holes 111 communicate with each other to form the appliance airflow passage 110. The first passages 415 are provided on the surface of the support base 41 facing the connection base 45, thereby simplifying the processing process of the support base 41 and improving the production speed of the support base 41. In yet another example, a portion of the one or more first passages 415 is provided inside the support base 41, and another portion is provided on the surface of the support base 41 facing the connection base 45.

[0107] An opening 17 is provided at the top of the housing 10, i.e., on the side of the receiving cavity 15 away from the bottom wall 13 of the housing 10. The dustproof assembly 90 covers the opening 17 to protect the equipment in the receiving cavity 15 and prevent external impurities such as dust and dirty water from entering the receiving cavity 15, ensuring the interior of the aerosol generating device 100 is cleaned and the internal devices operate normally. When the aerosol generating device 100 is in use, the movable member 93 moves relative to the fixed member 91 to open the insertion hole 910, allowing the mouthpiece 70 to pass through the insertion hole 910 and communicate with the substrate airflow passage 120. When the aerosol generating device 100 is not in use, the mouthpiece 70 can be removed from the insertion hole 910, and the movable member 93 moves relative to the fixed member 91 to cover the insertion hole 910, preventing external impurities such as dust and dirty water from entering the receiving cavity 15.

[0108] In some embodiments, the fixed member 91 includes a first cover 911 and a second cover 913.

The second cover 913 is provided on the second side 9113 of the first cover 911, the first cover 911 forms a moving groove 920 together with the second cover 913, the second cover 913 includes a second through hole 9131 penetrating therethrough, the second through hole 9131 forms an insertion hole 910 corresponding to the first through hole 9115, and the second cover 913 is fixedly connected to the cartridge assembly 40 and / or the main body member 31.

[0109] When the first cover 911 is connected to the main body member 31, the first cover 911 can be connected to both the second side 3133 of the abutting portion 313 and the third side 3135 of the abutting portion 313, thereby ensuring the stability of the first cover 911 covering the opening 17. At the same time, the first cover 911 can also be connected to the first side 3131 of the abutting portion 313, thereby preventing the first cover 911 from shifting when the movable member 93 moves relative to the fixed member 91 and ensuring the stability of the attachment of the dustproof assembly 90.

[0110] In some embodiments, the movable member 93 includes a moving member 931 and a biasing member 933. The moving member 931 is housed in the moving groove 920 and is movable relative to the fixed member 91 within the moving groove 920. The biasing member 933 is provided on the side of the second cover 913 away from the first cover 911, and is connected to the moving member 931.
