Understandably, the separating element 40 is made of hard plastic materials because the separating element 40 plays a role in fixing the bracket 30; at this time, providing the sealing member 90 made of a flexible silicone material between the second wall 44 of the partition 40 and the bracket 30 can improve the sealability to the first liquid guide hole 34, further improving the leakage-proof performance of the atomizer 100.

When the inner wall of the operating portion 301 gradually contacts the outer surface of the nozzle 11, the pressing portion 302 cannot be pressed downward, the pressing portion 302 can only be inserted into the nozzle 11 to a certain depth, and when the pressing portion 302 moves to a certain position, as shown in fig. 6, the first liquid guiding hole 34 on the second section 32 of the bracket 30 is completely staggered from the position of the sealing member 90. The liquid substrate in the liquid storage cavity 12 can enter the second liquid guiding element 60 through the first liquid guiding hole 34, enter the atomizing assembly 20 through the second liquid guiding hole 55 on the atomizing base 50, and be atomized by the heating element 21 to form aerosol, and the aerosol is output to the suction nozzle 110 through the air outlet channel 13 for the user to suck. The pressing portion 302 on the driving member 300 can be inserted into and removed from the nozzle opening 110, and can be made of flexible silicone material, the specific shape can be adjusted as required, and the shape of the driving member is similar to that of the nozzle 11, so that the pressing operation can be conveniently performed. Meanwhile, the operation part 301 is covered at the end part of the suction nozzle 11, so that the pollution to the suction nozzle 11 when the driving part 300 is operated can be avoided.

A partition member 40 is provided below the reservoir 121. in contrast to the embodiment described above, and as shown in fig. 11, the partition member 40 has a sleeve portion 47 provided around a portion of the outer wall surface of the second section 32 of the stent 30, and a plurality of ribs 48 provided on the outer wall of the sleeve portion 47. Specifically, four ribs 48 are provided at the outer periphery of the sleeve portion 47 at regular intervals symmetrically, and further extend longitudinally along the first housing 10. The outer wall surface of each rib 48 longitudinally abuts the inner wall of the first housing 10 to fix the partitioning member 40 inside the first housing 10. The length of the rib 48 in the longitudinal direction of the first housing 10 is larger than the length of the sleeve portion 47 in the longitudinal direction of the first housing 10. The rib 48 extends further in the lateral direction in the space below the sleeve portion 47 to abut against a part of the outer wall surface of the second section 32 of the stent 30, enhancing the circumferential fixing action of the stent 30. Before the atomizer 100 is not used, the first liquid guiding hole 34 on the second section 32 of the bracket 30 is closed by the sleeve portion 47, i.e., the sleeve portion 47 forms a shield 46 of the first liquid guiding hole 34.

The liquid substrate may enter the atomizing assembly 20 through the first liquid guide hole 34 and be atomized to form an aerosol. Understandably, the inner cavity of the driving member 300 can further form an output channel of the aerosol, when the limiting portion 330 of the driving member 300 is longitudinally abutted against the braking portion 340 inside the suction nozzle 11, the top end surface of the first section 310 is flush with the end surface of the suction nozzle 11, at this time, the driving member 300 is completely inserted into the suction nozzle 11, the operation and use of the aerosol generating device by a user are not affected, and the driving member 300 does not need to be removed out of the suction nozzle 11.

Understandably, in the third embodiment provided by the present application, the above-mentioned cylindrical driving member 300 can be integrally formed with the bracket 30, that is, when the bracket 30 is at the first position, the end of the bracket 30 extends to the outside of the nozzle opening 110, and the first liquid guiding hole 34 on the bracket 30 is shielded by the shielding member 46; the exposed section of the bracket 30 forms an operation part, and a user can directly press the exposed section of the bracket 30 downwards along the longitudinal direction of the shell 10, so that the bracket 30 moves longitudinally relative to the shell 10; when the bracket 30 is driven by external force from the end, and moves down along the housing 10 longitudinally until the top end surface of the bracket 30 is flush with the end surface of the suction nozzle 11, the bracket 30 is in the second position, at this time, the first liquid guiding hole 34 on the bracket 30 is staggered with the position of the shielding member 46 and is communicated with the second liquid storage cavity 122, the liquid matrix can enter the atomizing assembly 20 through the first liquid guiding hole 34,

in the above three embodiments, when the support 30 is in the first position, the heating element 21 of the atomizing assembly 20 is electrically connected to the electrode 71 through a wire, and then electrically connected to the power supply 83 through the electrode 71, wherein the electrode 71 is fixed inside the housing 10; or the heating element 21 is electrically connected to the power source 83 directly by a wire. When the support 30 is in the first position, the wire connecting the heating element 21 and the electrode 71 of the atomizing assembly 20 is in tension; when the holder 30 is in the second position, the wires connecting the heating element 21 and the electrode 71 of the atomizing assembly 20 are in a relatively loose state. Still further, the present application provides another embodiment, as shown in fig. 12 and 13, in which the heating element 21 inside the atomizer 100 is electrically connected to the first electrical connector 73, the power source 83 inside the power supply module 200 is electrically connected to the second electrical connector 74, and when the bracket 30 is in the first position, the first electrical connector 73 and the second electrical connector 74 are in the disconnected state, and the heating element 21 cannot be electrically driven by the power supply module 200. As the holder 30 moves down in the longitudinal direction of the housing 10, the heating element 21 housed inside the holder 30 moves down together with the first electrical connector 73, the first electrical connector 73 being in progressive contact with the second electrical connector 74; when the bracket 30 is in the second position, the first electrical connector 73 is in communication with the second electrical connector 74, and the heating element 21 is electrically driven by the power module 200. Understandably, before the aerosol generating device is not used, the bracket 30 is always in the first position, at this time, the heating element 21 of the atomizing assembly 20 is in a power-off state, even if air pressure changes in the aerosol generating device, the air flow induction switch 86 in the aerosol generating device is triggered by mistake, and the heating element 21 of the atomizing assembly 20 is disconnected from the power supply 83, the atomizing assembly 71 cannot work, so that the heating element 21 can be prevented from being started to work and damaging the heating element 21 under the condition that no liquid substrate is supplied. The first electrical connection member 73 may be an elastic electrode or an elastic contact, and is made of a metal or an alloy material with good electrical conductivity. The second electrical connector 74 may be a conductive contact connected to the power source 83 and made of a metal or alloy material having good electrical conductivity.
