[0035] The mounting frame 21 has a mounting hole 211, the elastic arm 22 and the carrier plate 23 are located in the mounting hole 211, and the two ends of the elastic arm 22 are connected to the mounting frame 21 and the carrier plate 23 respectively, the elastic arm 22 is mounted on one side of the carrier plate 23 and exposed to the shell 1 through the assembly hole 11 to accept the pressing force, the elastic arm 22 is used to produce elastic deformation when the pressing part 3 accepts the pressing force, and under the action of the elastic recovery force, the carrier plate 23 is reset when the pressing force is removed, and then the resistance can be provided by the elastic arm 22 when pressing to improve the hand feeling of the user when pressing.
[0036] Optionally, the pressing part 3 is a metal piece, which will not deform, thereby avoiding the hand feeling problem caused by the pressing deformation when the pressing part 3 is a soft rubber and the length is relatively long.
[0037] As shown in Figure 3 and Figure 4 , the pressing part 3 is provided with a mounting groove 31, and the carrier plate 23 is provided with a clamping protrusion 231, the clamping protrusion 231 is clamped in the mounting groove 31 in interference, so as to realize the fixed connection of the pressing part 3 and the carrier plate 23. Specifically, the mounting groove 31 and / or the clamping protrusion 231 is provided with a rib, so that the fixed connection of the pressing part 3 on the carrier plate 23 can be realized through the interference of the rib. Optionally, the mounting groove 31 is provided with an adhesive protrusion 32, the clamping protrusion 231 is provided with an adhesive groove 232, and the adhesive protrusion 32 is arranged in the adhesive groove 232, so as to be fixed through the adhesive, and the connection strength of the pressing part 3 on the carrier plate 23 is further strengthened.
[0038] In an embodiment, as shown in Figure 2 , the carrier plate 23 has a first end and a second end arranged oppositely along the length direction thereof, and the elastic arm 22 includes four, two of the four elastic arms 22 are connected to each other and surround the first end of the carrier plate 23, and the other two of the four elastic arms 22 are connected to each other and surround the second end of the carrier plate 23, so that through the arrangement of the four elastic arms 22, the hand feeling of the two ends and the three different positions in the middle of the pressing part 3 can be ensured to be consistent when pressing in the case that the pressing part 3 is long strip-shaped.
[0039] It should be noted that the pressing force can be adjusted by adjusting the length, shape, thickness, width and other parameters of the elastic arm 22, the elastic deformation amplitude of the elastic arm 22 is different when the above parameters are different, and then the elastic recovery force is different, and the resistance provided by the elastic recovery force is also different, so that the hand feeling of the user when pressing is also different. Optionally, the length of the elastic arm 22 is 5mm-8mm, so as to achieve a more comfortable pressing feeling by adjusting the length of the elastic arm 22.
[0040] In another embodiment, as shown in Figure 5As shown, the carrier plate 23 has a first end and a second end oppositely arranged along the length direction thereof, and the elastic arms 22 include two, one of the two elastic arms 22 surrounds the first end of the carrier plate 23, and the other of the two elastic arms 22 surrounds the second end of the carrier plate 23, so that by arranging the two elastic arms 22, the two ends and the three different positions in the middle of the pressing part 3 can have a relatively consistent feeling when pressed in the case that the pressing part 3 is long and strip-shaped.
[0041] The elastic arm 22 arranged around the first end is symmetrically arranged with the elastic arm 22 arranged around the second end, further ensuring that a relatively consistent feeling can be obtained when the two ends of the pressing part 3 are pressed.

The aerosol can be generated by heating and volatilizing part of the active substance filled in the cigarette, and the user can inhale the aerosol by sucking at the filter of the cigarette.
[0043] When the aerosol generating article is liquid, the receiving chamber is used to store an atomizable liquid substrate. The aerosol generating device further includes a liquid guide element, and the heating element is combined with the liquid guide element. The liquid substrate flows to the liquid guide element through an internal liquid channel, and then is further transmitted to the heating element by the liquid guide element. The heating element can heat and atomize the transmitted liquid substrate to generate an aerosol.
