[0041] 1 to 3 , an embodiment of the present application provides an aerosol generating device 1 , which can be used to heat an aerosol generating substrate. The aerosol generating substrate generates an aerosol for inhalation by a user after being heated.

[0042] The aerosol generating device 1 comprises a housing assembly 10 , at least two heating elements 20 , an air regulating switch 30 and a propulsion switch 40 .

[0043] At least two heating elements 20 are arranged in parallel within the housing assembly 10, so that each of the at least two heating elements 20 can operate independently, or some or all of the heating elements 20 can operate together. When in operation, the heating elements 20 can be used to heat the aerosol-generating substrate. For example, an atomization pipe 15 can be provided within the housing assembly 10, and the heating element can be located within the atomization pipe 15.

[0044] The at least two heating elements 20 may refer to a plurality of heating elements 20 . For example, the at least two heating elements 20 may refer to two heating elements 20 , three heating elements 20 , four heating elements 20 or other numbers of heating elements 20 .

[0045] For example, the following description is made by taking the at least two heating elements 20 including two heating elements 20 as an example, and the two heating elements 20 are respectively named as a first heating element 21 and a second heating element 23 .

[0046] The shell assembly 10 is provided with an air duct 111, which has an air inlet 1111. The air outlet of the air duct 111 can be connected to the atomization pipe 15. The air inlet 1111 can be used to connect to the external environment so that external air can enter the air duct 111 and then enter the atomization pipe 15 through the air duct 111 to drive the aerosol in the atomization pipe 15 to flow and be inhaled by the user.

[0047] The gas adjustment switch 30 is movably connected to the housing assembly 10 and is located at one end of the air inlet 1111. The push switch 40 is electrically connected to the heating element 20. The gas adjustment switch 30 and the push switch 40 are linked, so that when the gas adjustment switch 30 moves relative to the housing assembly 10, it can also move the push switch 40. This allows the user to adjust the push switch 40 simultaneously by adjusting the gas adjustment switch 30 once, helping to reduce the possibility of misoperation, improving the user experience, and facilitating operation.

[0048] The gas regulating switch 30 moves relative to the shell assembly 10 to adjust the size of the area of ​​the air inlet 1111, and drives the propulsion switch 40 to adjust the working quantity of the heating element 20. Therefore, when the user adjusts the gas regulating switch 30, not only can the area of ​​the air inlet 1111 be adjusted to control the flow rate of the aerosol, but the propulsion switch 40 can also be driven to move synchronously to adjust the working quantity of the heating element 20 and the speed of generating aerosol by the aerosol generating device 1, thereby meeting the diverse needs of users and being easy to operate.

[0049] The air regulating switch 30 is movable relative to the housing assembly 10 to adjust the size of the air inlet 1111. This may mean that when the air regulating switch 30 is movable, the air inlet 1111 is opened or closed to adjust the size of the air inlet 1111. The air regulating switch 30 may completely cover the air inlet 1111, partially cover the air inlet 1111, or completely open the air inlet 1111.

[0050] For example, when the number of working heating elements 20 increases, the contact area between the heating elements 20 and the aerosol generating substrate increases, and the aerosol is generated faster, then a larger air inlet 1111 is required to increase the flow rate of the aerosol. Therefore, when the number of working heating elements 20 increases, the area of ​​the air inlet 1111 of the air duct 111 becomes larger. Specifically, when all heating elements 20 are working, the air regulating switch 30 can fully open the air inlet 1111 to maximize the flow rate of the aerosol; when one or part of the heating elements 20 are working, the air regulating switch 30 can partially cover the air inlet 1111; when all heating elements 20 stop working, the air regulating switch 30 can completely cover the air inlet 1111, which helps to reduce the entry of impurities such as dust and liquid into the air duct 111.

[0051] In one embodiment, the aerosol generating device 1 may include a nozzle 60, which can be connected to the shell assembly 10 and connected to the atomization pipe 15, that is, the airway 111, the atomization pipe 15 and the nozzle 60 are connected in sequence. The user can inhale the aerosol through the nozzle 60, driving the air from the external environment to enter the airway 111 from the air inlet 1111, and then enter the atomization pipe 15 through the airway 111 to drive the aerosol in the atomization pipe 15 to flow, and the aerosol flows to the nozzle 60 to be inhaled by the user.

[0052] In one embodiment, the housing assembly 10 may include a housing body 11 and a control panel 13 , wherein the control panel 13 , the air duct 111 , the heating element 20 and the air regulating switch 30 are all disposed in the housing body 11 .

[0053] The propulsion switch 40 can be set on the control board 13, and the heating element 20 can be electrically connected to the control board 13. The propulsion switch 40 can be electrically connected to the control board 13, so that when the propulsion switch 40 is active, the working quantity of the heating element 20 can be controlled by the control board 13.

[0054] In one embodiment, the suction nozzle 60 and the control panel 13 can be located on opposite sides of the shell body 11 along the length direction, the control panel 13 can be located inside the shell body 11, and the propulsion switch 40 and the air regulating switch 30 are both located on the side of the control panel 13 away from the suction nozzle 60.

[0055] In one embodiment, the shell assembly 10 may further include a battery 70, which may be disposed in the shell body 11. The battery 70 may be electrically connected to the control board 13 to provide electrical energy to the control board 13, and the control board 13 transfers the electrical energy to components such as the heating element 20.

[0056] In one embodiment, the control board 13 can be provided with a positive electrode connection portion and multiple negative electrode connection portions, each heating element 20 has a positive electrode pin 211 and a negative electrode pin, the positive electrode pin 211 of each heating element 20 is electrically connected to the positive electrode connection portion, and the negative electrode pins of different heating elements 20 are electrically connected to different negative electrode connection portions; when the heating element 20 is in a working state, the positive electrode pin 211 and the positive electrode connection portion of the same heating element 20 are conductive, and the negative electrode pin and the negative electrode connection portion are conductive, so that the positive electrode pin 211 and the negative electrode pin of the heating element 20 are conductive, and the heating element 20 converts electrical energy into thermal energy to heat the aerosol generation matrix.

[0057] Exemplarily, the control board 13 may be provided with a negative electrode connection portion and multiple positive electrode connection portions, each heating element 20 has a negative electrode pin and a positive electrode pin, the negative electrode pin of each heating element 20 is electrically connected to the negative electrode connection portion, and the positive electrode pins of different heating elements 20 are electrically connected to different positive electrode connection portions; when the heating element 20 is in a working state, the negative electrode pin and the negative electrode connection portion of the same heating element 20 are conductive, and the positive electrode pin and the positive electrode connection portion are conductive, so that the negative electrode pin and the positive electrode pin of the heating element 20 are conductive, and the heating element 20 converts electrical energy into thermal energy to heat the aerosol generation matrix.

[0058] In one embodiment, when at least two heating elements 20 are connected in parallel, all or part of the at least two heating elements 20 can share the positive pin 211 or the negative pin to reduce the connection difficulty and also reduce the layout difficulty of the control board 13.

[0059] For example, the first heating element 21 and the second heating element 23 share a positive electrode pin 211. The first heating element 21 may further include a first negative electrode pin 213, and the second heating element 23 may further include a second negative electrode pin 231. Correspondingly, the control board 13 may be provided with a positive electrode connection portion, a first negative electrode connection portion, and a second negative electrode connection portion. The positive electrode pin 211 shared by the first heating element 21 and the second heating element 23 may be connected to the positive electrode connection portion. The first negative electrode pin 213 of the first heating element 21 may be connected to the first negative electrode connection portion, and the second negative electrode pin 231 of the second heating element 23 may be connected to the second negative electrode connection portion. When the first heating element 21 is operating, the positive electrode pin 211 and the first negative electrode pin 213 of the first heating element 21 are both conductive, and the first heating element 21 is energized. When the second heating element 23 is operating, the positive electrode pin 211 and the second negative electrode pin 231 of the second heating element 23 are both conductive, and the second heating element 23 is energized.

[0060] In one embodiment, the aerosol generating device 1 may include multiple working modes. When the aerosol generating device 1 is in different working modes, the area of ​​the air inlet 1111 is different, and the working number of the heating element 20 is different. The aerosol generating device 1 can correspond to different areas of the air inlet 1111 and working numbers of the heating element 20 in different working modes, thereby reducing user misoperation.

[0061] Exemplarily, the multiple operating modes may include a first operating mode, a second operating mode, and a third operating mode. In the first operating mode, the gas regulating switch 30 may fully open the air inlet 1111, and all the heating elements 20 may be in operation. In the second operating mode, the gas regulating switch 30 may partially block the air inlet 1111, for example, the gas regulating switch 30 may block half of the air inlet 1111, and one or some of the multiple heating elements 20 may be in operation. In the third operating mode, the gas regulating switch 30 may completely block the air inlet 1111, and all the heating elements 20 may stop working.

[0062] For example, for the second working mode, the air regulating switch 30 adjusts the size of the area shielding the air inlet 1111, and correspondingly, the working number of the heating element 20 can also be adjusted. Therefore, the aerosol generating device 1 can include multiple second working modes, and the multiple second working modes can include a first sub-mode, a second sub-mode, a third sub-mode, and so on.

[0063] In one embodiment, the air-regulating switch 30 can slide relative to the housing assembly 10 to adjust the size of the air inlet 1111 and drive the push switch 40 to slide to adjust the number of heating elements 20 in operation. By sliding the air-regulating switch 30, the user can simultaneously slide the push switch 40, thereby adjusting the area of ​​the air inlet 1111 and the number of heating elements 20 in operation. This structure is relatively simple and easy to implement. For example, in FIG5 , the air-regulating switch 30 can slide left and right, driving the push switch 40 to slide left and right.

[0064] In one embodiment, the housing body 11 may be provided with a slide groove, and the gas regulating switch 30 may be slidably located in the slide groove.

[0065] Referring to Figures 2, 4 and 8, in one embodiment, the air regulating switch 30 may include a connected toggle member 31 and a sliding member 33, the toggle member 31 being at least partially exposed from the housing assembly 10, the sliding member 33 being connected to the push switch 40, the toggle member 31 being used to drive the sliding member 33 to slide relative to the housing assembly 10 to adjust the opening area of ​​the air inlet 1111, and to drive the push switch 40 to slide to adjust the working quantity of the heating element 20, so that the user can toggle the toggle member 31 to drive the sliding member 33 to slide, thereby opening or covering the air inlet 1111, and when the sliding member 33 slides, it can drive the push switch 40 to slide, thereby controlling the working quantity of the heating element 20, so that the user can adjust the size of the air inlet 1111 and the working quantity of the heating element 20 at the same time by toggling the toggle member 31 once.

[0066] In one embodiment, the shell assembly 10 can be provided with a plurality of limit grooves 113, and the plurality of limit grooves 113 are distributed in sequence on the sliding path of the gas regulating switch 30. The gas regulating switch 30 includes a limit protrusion 333. When the aerosol generating device 1 is in different working modes, the limit protrusion 333 is engaged in different limit grooves 113, so that the user can more accurately adjust the working mode of the aerosol generating device 1, reduce the possibility of misoperation, and improve the user's experience.

[0067] For example, the slider 33 may be provided with stopper protrusions 333 on opposite sides along the sliding direction. Both sides of the slider 33 are slidably connected to the housing 11, and a plurality of stopper grooves 113 are provided on the side where the housing 11 and the slider 33 are connected. When the toggle member 31 drives the slider 33 to slide, the stopper protrusions 333 on both sides of the slider 33 can snap into the stopper grooves 113. When the aerosol generating device 1 is in different operating modes, the stopper protrusions 333 can snap into the corresponding stopper grooves 113.

[0068] For example, the positions of the limiting groove 113 and the limiting protrusion 333 can also be interchanged. Specifically, the housing assembly 10 can also be provided with multiple limiting protrusions 333, and the multiple limiting protrusions 333 are sequentially distributed along the sliding path of the gas regulating switch 30. The gas regulating switch 30 can also include a limiting groove 113. When the aerosol generating device 1 is in different operating modes, the limiting groove 113 is engaged with different limiting protrusions 333.

[0069] 4 to 5 , in one embodiment, the sliding member 33 may be provided with a through hole 331, and the sliding member 33 slides relative to the shell assembly 10 to adjust the communication area between the through hole 331 and the air inlet 1111. The through hole 331 may be used to connect the air inlet 1111 and the external environment. When the sliding member 33 slides, the position of the through hole 331 relative to the air inlet 1111 may be adjusted so that the through hole 331 can be fully or partially connected to the air inlet 1111 or the sliding member 33 covers the air inlet 1111, thereby adjusting the working mode of the aerosol generating device 1.

[0070] Exemplarily, the through hole 331 can be connected to the slide groove on the shell body 11, and the slide groove can be connected to the external environment. When the through hole 331 and the air inlet 1111 are connected, the external air can pass through the slide groove and the through hole 331 in sequence, and then enter the air duct 111 through the air inlet 1111.

[0071] 2 , 4 and 5 , in one embodiment, the number of through holes 331 may be multiple, and the sliding member 33 slides relative to the shell assembly 10 to adjust different numbers of through holes 331 connected to the air inlet 1111, thereby controlling the number of through holes 331 connected to the air inlet 1111. Different numbers of through holes 331 connected to the air inlet 1111 can be adjusted to adjust the area of ​​the air inlet 1111, which helps to more accurately control the area of ​​the air inlet 1111 opened, thereby more stably controlling the aerosol flow rate and improving the user experience.

[0072] The term "plurality" may refer to two or more than two, i.e., the sliding member 33 may be provided with two through holes 331, three through holes 331, four through holes 331, or any other number of through holes 331. For ease of description, the following explanation is based on an example in which the sliding member 33 is provided with three through holes 331, which are respectively named a first hole 3311, a second hole 3313, and a third hole 3315.

[0073] For example, in different working modes, the number of through holes 331 communicating with the air inlet 1111 is also different.

[0074] In one embodiment, the plurality of through holes 331 can be arranged as required.

[0075] In one embodiment, the diameters of the plurality of through holes 331 may be the same or different.

[0076] 4 to 5 , in one embodiment, the aerosol generating device 1 may further include a sealing member 80 , which may abut between the shell assembly 10 and the sliding member 33 , the air passage 111 passing through the sealing member 80 , the air inlet 1111 may be provided on the sealing member 80 , and the sliding member 33 may slide relative to the shell assembly 10 to adjust the communication between different numbers of through holes 331 and the air inlet 1111 , thereby improving the air leakage at the air inlet 1111 .

[0077] Exemplarily, the seal 80 can be located inside the shell body 11, and a sealing boss can be provided on the side of the seal 80 facing away from the suction nozzle 60, the air duct passes through the sealing boss, the air inlet 1111 can be provided on the sealing boss, the control panel 13 can be provided with a mounting hole 131, the sealing boss can be passed through the mounting hole 131 and abut against the sliding member 33 to seal the air inlet 1111, which helps to avoid failure of the air regulating switch 30 due to air leakage at the air inlet 1111.

[0078] For example, when the aerosol generating device 1 is not provided with a seal 80, the air regulating switch 30 can be attached to the control panel 13, the mounting hole 131 can connect the air duct 111 and the external environment, and the air inlet 1111 can be provided at the mounting hole 131. Then, when the sliding member 33 slides relative to the shell assembly 10, the size of the area of ​​the mounting hole 131 can be adjusted, or the connection area between the through hole 331 and the mounting hole 131 can be adjusted, or different numbers of through holes 331 and the mounting hole 131 can be adjusted to be connected.

[0079] For example, in the first operating mode, as shown in FIG6 , the first hole 3311, the second hole 3313, and the third hole 3315 can each be connected to the external environment and the air inlet 1111, and air from the external environment can enter the air inlet 1111 through the first hole 3311, the second hole 3313, and the third hole 3315. The first heating element 21 and the second heating element 23 can both be in an operating state. In the second operating mode, as shown in FIG5 , the first hole 3311 and the second hole 3313 can each be connected to the external environment and the air inlet 1111, and air from the external environment can enter the air inlet 1111 through the first hole 3311 and the second hole 3313. One of the first heating element 21 and the second heating element 23 is in an operating state. In the third working mode, as shown in FIG7 , the first hole 3311 , the second hole 3313 and the third hole 3315 are all staggered with the air inlet 1111 , the sliding member 33 covers the air inlet 1111 , and the first heating element 21 and the second heating element 23 are both in a stopped state.

[0080] In one embodiment, the sealing member 80 may be made of an elastic material to improve the sealing effect. For example, the sealing member 80 may be a silicone seal.

[0081] For example, in addition to being able to adjust the size of the area of ​​the air inlet 1111 by sliding, the air regulating switch 30 can also be able to adjust the size of the area of ​​the air inlet 1111 by rotating.

[0082] For example, the air regulating switch 30 rotates relative to the shell assembly 10 to adjust the size of the area of ​​the air inlet 1111, and drives the push switch 40 to slide to adjust the working quantity of the heating element 20. The user can rotate the air regulating switch 30 to make the push switch 40 slide synchronously, and then adjust the working quantity of the heating element 20 while adjusting the area of ​​the air inlet 1111. Therefore, the air regulating switch 30 can have multiple structures to meet the different needs of users.

[0083] In the aerosol generating device 1 provided in the embodiments of the present application, at least two heating elements 20 are arranged in parallel within the housing assembly 10, so that each of the at least two heating elements 20 can operate independently. The housing assembly 10 is provided with an air passage 111, and the air passage 111 has an air inlet 1111. The air inlet 1111 can be used to communicate with the external environment so that external air can enter the air passage 111. The air regulating switch 30 can be movably connected to the shell assembly 10 and is located at one end of the air inlet 1111. The push switch 40 is electrically connected to the heating element 20. The air regulating switch 30 and the push switch 40 are linked. The air regulating switch 30 moves relative to the shell assembly 10 to adjust the size of the area of ​​the air inlet 1111 and drive the push switch 40 to adjust the working number of the heating element 20. Therefore, when the air regulating switch 30 moves relative to the shell assembly 10, it can drive the push switch 40 to move together, so that the user can adjust the size of the area of ​​the air inlet 1111 and the working number of the heating element 20 by adjusting the air regulating switch 30 once, which helps to reduce misoperation and is easy to operate.
