[0036] In addition, the anti-extraction pin 14 can be connected with the metal shell or the metal decorative sheet, and can prevent electrical malfunctions and other problems.

[0037] In some embodiments, the display screen support 3 is provided with a circuit board 5 away from one side of the button 2, the button 2 has an extension 22, and the extension 22 penetrates the display screen support 3 and abuts against the circuit board 5.

[0038] In the embodiment, the display screen support 3 is provided with a circuit board 5 away from one side of the button 2, the button 2 has an extension 22, and the extension 22 penetrates the display screen support 3 and abuts against the circuit board 5, when the button 2 is pressed, the extension 22 of the button 2 can apply force to the circuit board 5 to make the aerosol forming device work.

[0039] In some embodiments, a elastic piece 23 is clamped between the button 2 and the display screen support 3, and a pressing silica gel 24 is arranged on at least one side of the extension 22 facing the circuit board 5.

[0040] In the embodiment, a elastic piece 23 is clamped between the button 2 and the display screen support 3, when the button 2 is in a non-pressed state, the extension 22 of the button 2 does not apply force to the circuit board 5, preventing the extension 22 of the button 2 from applying force to the circuit board 5 to make the aerosol forming device work when the button 2 is in a non-pressed state, and causing accidents; a pressing silica gel 24 is arranged on at least one side of the extension 22 facing the circuit board 5, and the pressing silica gel 24 can improve the pressing touch of the user and the user experience.

[0041] In some embodiments, the mouth of the mounting hole 11 is provided with a decorative sheet 13, the decorative sheet 13 has an extension opening 131 matched with the key 2, the key 2 partially extends to the side of the decorative sheet 13 away from the display screen support 3 via the extension opening 131.

[0042] In the embodiment, the mouth of the mounting hole 11 is provided with a decorative sheet 13, the decorative sheet 13 has an extension opening 131 matched with the key 2, the key 2 partially extends to the side of the decorative sheet 13 away from the display screen support 3 via the extension opening 131, the decorative sheet 13 can cover the mounting hole 11, the assembly groove 12, the anti-falling pin 4 and the plug-in hole 31, improve the appearance of the aerosol forming device, and also prevent the anti-falling pin 4 from falling out of the plug-in hole 31, make the key 2 exit from the mounting hole 11 via the assembly groove 12, affect the use of the key 2, and improve the stability of the aerosol forming device.

[0043] In some embodiments, the height H1 of the key 2 extending out of the extension opening 131 in the non-pressing state is not greater than 0.2 mm.

[0044] Since the height H1 of the key 2 extending out of the extension opening 131 in the non-pressing state of the existing aerosol forming device is generally not less than 0.9 mm, since the height H1 of the key 2 extending out of the extension opening 131 in the non-pressing state of the existing aerosol forming device is large, the key 2 is easy to cause accidental ignition, and occupies a large structure space, and the user experience is poor.

[0045] In the embodiment, the height H1 of the key 2 extending out of the extension opening 131 in the non-pressing state is not greater than 0.2 mm, which can prevent the key 2 from accidental ignition, improve the safety performance of the aerosol forming device, and occupy a small structure space, and improve the user experience.

[0046] In some embodiments, in the axial direction of the key 2, the distance H2 between the key 2 and the display screen support 3 is less than the thickness H3 between the side of the decorative sheet 13 away from the display screen support 3 and the inner wall of the lower shell 1.

[0047] Since the distance H2 between the key 2 and the display screen support 3 of the existing aerosol forming device is greater than the thickness H3 between the side of the decorative sheet 13 away from the display screen support 3 and the inner wall of the lower shell 1, the axial stroke of the key 2 is too large when the key 2 is pressed, the key 2 is completely sunk into the inside of the lower shell 1, the key 2 is easy to interfere with the inner wall of the lower shell 1 when reset, the key 2 is stuck and cannot be reset, and safety hazards are caused.

[0048] In the embodiment, the distance H2 between the key 2 and the display screen support 3 in the axial direction of the key 2 is smaller than the thickness H3 between the side of the decorative sheet 13 away from the display screen support 3 and the inner wall of the lower shell 1. Even when the key 2 is pressed to the low position of the key 2 and the display screen support 3, part of the key 2 is still located in the mounting hole 11 and does not completely sink into the inner wall of the lower shell 1, thus preventing the key 2 from being stuck and improving the safety performance of the aerosol forming device.

[0049] In some embodiments, the lower shell 1 is provided with a support 6, the circuit board 5 is arranged on the support 6, and the display screen support 3 is fixed on the circuit board 5.

[0050] In the embodiment, the lower shell 1 is provided with a support 6, the circuit board 5 is arranged on the support 6, and the display screen support 3 is fixed on the circuit board 5.

[0051] In some embodiments, the inner diameter of the extension hole 131 is not less than the inner diameter of the mounting hole 11, and the inner diameter of the mounting hole 11 is greater than the outer diameter of the key 2.

[0052] Since the inner diameter of the extension hole 131 of the existing decorative sheet 13 is greater than the inner diameter of the mounting hole 11, when the key 2 is reset, the top of the key 2 is easy to interfere with the decorative sheet 13, causing the key 2 to be stuck.

[0053] In the embodiment, the inner diameter of the extension hole 131 is not less than the inner diameter of the mounting hole 11, and the inner diameter of the mounting hole 11 is greater than the outer diameter of the key 2. When the key 2 is reset, the top of the key 2 is prevented from interfering with the decorative sheet 13, causing the key 2 to be stuck, thereby improving the safety performance of the product.

[0054] In some embodiments, the circuit board 5 is provided with at least two toggle switches 7, the lower shell 1 is further provided with an atomizing core assembly 8, the at least two toggle switches 7 correspond to different output powers of the atomizing core assembly 8, the toggle switch 7 extends to the side of the display screen support 3 away from the circuit board 5, the outer periphery of the key 2 is further provided with a toggle portion 26, the toggle switch 7 is located on the rotation path of the toggle portion 26, and the key 2 has an adjusting hole 25.

[0055] In the embodiment, at least two toggle switches 7 are arranged on the circuit board 5, and the lower shell 1 is further provided with an atomizing core assembly 8. The at least two toggle switches 7 correspond to different output powers of the atomizing core assembly 8 respectively. The toggle switches 7 can be arranged in plurality, and the plurality of toggle switches 7 correspond to a plurality of different output powers of the atomizing core assembly 8 respectively. The toggle switches 7 extend to a side of the display screen support 3 away from the circuit board 5. The outer periphery of the button 2 is further provided with a toggle portion 26. The toggle switches 7 are located on the rotation path of the toggle portion 26. Specifically, since the toggle switches 7 are located on the rotation path of the toggle portion 26, when the button 2 is rotated, the toggle portion 26 can toggle different toggle switches 7. The different toggle switches 7 correspond to different output powers of the atomizing core assembly 8 respectively. Therefore, the button 2 can adjust the output power of the atomizing core assembly 8. The initial state can be set as a small power output or a zero power output. Specifically, when the stop edge 21 of the button 2 is in contact with the anti-extraction pin 14, the toggle portion 26 corresponds to a zero power output or a small power output. This prevents the occurrence of electrical faults during disassembly. It is also beneficial for assembling in a low power mode and reducing the user's dependence on aerosols.
