In other words, the aerosol generating device can be adapted to atomizing matrices of different manufacturers. Among them, the atomizing section of the atomizing matrix is ​​the tobacco section of the traditional cigarette cartridge, that is, the part that can be heated to produce smoke.

[0038] Please refer to Figures 1 to 6 The aerosol generating device of this embodiment mainly includes an atomizing shell 1 , an atomizing assembly 2 and a driving assembly 3 , and the atomizing assembly 2 and the driving assembly 3 are installed in the atomizing shell 1 .

[0042] The opening of the atomizing chamber 210 can be directly connected to the plug interface 12, and a first sealing member 24 can also be provided between the opening of the atomizing chamber 210 and the plug interface 12. The first sealing member 24 seals the connection between the opening of the atomizing chamber 210 and the plug interface 12 to prevent the opening of the atomizing chamber 210 from being connected to the accommodating chamber 11, thereby preventing the smoke generated by heating from entering the accommodating chamber 11.

The upper mounting seat 21 and the lower mounting seat 23 are respectively fixedly mounted on the bracket of the accommodating cavity 11, or directly mounted on the inner wall of the atomizer shell 1. One end of the heating tube 22 is fixedly connected to the upper mounting seat 21, and the other end of the heating tube 22 is fixedly connected to the lower mounting seat 23. The upper mounting seat 21 and the lower mounting seat 23 respectively have through holes, one end of the heating tube 22 is inserted into the through hole of the upper mounting seat 21, and the other end of the heating tube 22 is inserted into the through hole of the lower mounting seat 23. The heating tube 22 forms a sealed connection with the upper mounting seat 21 and the lower mounting seat 23.

[0045] The heating tube 22 includes a metal tube and a heating plate. The heating plate can be attached to the circumferential outer side or the axial inner side of the metal tube. The heating plate can heat the metal tube. This heating tube 22 belongs to a resistance heating structure. In other embodiments, the heating tube 22 can include a metal tube and an electromagnetic induction coil. The electromagnetic induction coil is located on the circumferential outer side of the metal tube. The electromagnetic induction coil can electromagnetically heat the metal tube.

The heating chamber 211 can be plugged in and heat the atomization matrix 4, and the non-heating chamber 212 can be plugged in the atomization matrix 4, but the atomization matrix 4 cannot be heated.

[0047] The atomizing chamber 210 is sequentially distributed with a non-heating chamber 212, a heating chamber 211, and a non-heating chamber 212 along the axial plugging direction from the opening. The heating chamber 211 is located in the middle of the atomizing chamber 210. This arrangement allows the atomizing section 41 of the atomizing matrix 4 to be inserted into the non-heating chamber 212 at the bottom of the atomizing chamber 210, and then moved to the heating chamber 211 in the middle by the driving assembly 3, so that the entire atomizing section 41 is heated sequentially.

In other words, the segmented heating of the atomizing section 41 can be achieved, and the segmented heating of the atomizing section 41 can effectively control the amount of smoke, so that the user can be in the reheated atomizing section 41 area every time he smokes, that is, the continuous good feeling after smoking can be maintained, and the problem of the overall heating of the atomizing section 41 causing the taste to decrease in the later stage of smoking can be avoided; and the length of the heating tube 22 can also be shortened to reduce costs.

[0051] In other embodiments, the length of the heating tube 22 may be equal to or greater than the length of the atomizing section 41 of the atomizing substrate 4 of all or most manufacturers, that is, the axial length of the heating chamber 211 is equal to or greater than the axial length of the atomizing section 41. In this case, the atomizing section 41 is inserted into the bottom of the atomizing chamber 210 in the initial state, and segmented heating of the atomizing section 41 can also be achieved.

[0052] In the present embodiment, the driving assembly 3 includes a driving member 31, a transmission assembly 32 and a pushing member 33. The driving member 31 can be a combination of a motor and a reduction box. The driving member 31 has an output shaft.

The driving member 31 is used to drive the pushing member 33 to move axially in a straight line in the through hole of the lower mounting seat 23 through the transmission assembly 32, that is, the driving member 31 is used to drive the pushing member 33 to move axially in the non-heating chamber 212 at the bottom of the atomizing chamber 210 through the transmission assembly 32.

[0053] In this embodiment, the drive assembly 3 is provided with the transmission assembly 32 which can not only convert the rotary pair into a linear motion pair, but also improve the output stability and facilitate the installation of the drive member 31 .

[0054] In other embodiments, the driving component 3 may also include a driving member 31 and a pushing member 33, that is, the driving component 3 does not include a transmission component 32, the driving member 31 can be a linear motor, the output shaft of the linear motor is inserted into the atomization chamber 210 and fixedly connected to the pushing member 33, the linear motor can directly output a linear pair, that is, the linear motor can directly drive the pushing member 33 to move axially in the non-heating chamber 212 at the bottom of the atomization chamber 210.

[0055] In this embodiment, the method of using the aerosol generating device is as follows:

[0056] Please refer to Figure 5 In the initial state, the atomizing section 41 of the atomizing substrate 4 is inserted into the bottom of the atomizing chamber 210, so that the lower end of the atomizing section 41 is located in the non-heating chamber 212, and the upper end of the atomizing section 41 is located in the heating chamber 211; the heating is started, and the heating tube 22 first heats and atomizes the upper end of the atomizing section 41 in the heating chamber 211;

[0057] Please refer to Figure 6After a certain period of inhalation, the driving component 3 is started, and the driving component 3 pushes the atomizing matrix 4 to move upward as a whole through the pushing member 33, that is, the atomizing section 41 is pushed to move toward the opening of the atomizing chamber 210, so that the middle part or the lower end of the atomizing section 41 that is not heated moves into the heating chamber 211; the heating is started, and the heating tube 22 first heats and atomizes the middle part or the lower end of the atomizing section 41 in the heating chamber 211.

[0058] The driving component 3 can be pushed twice, three times or more times according to the length of the atomizing section 41 to achieve sequential heating of the entire area of ​​the atomizing section 41. In addition, the movement of the atomizing section 41 driven by the driving component 3 can be set to be a slow and gradual push or an intermittent push.

[0059] The aerosol generating device of the embodiment of the present embodiment is provided with a driving component 3, and the pushing member 33 of the driving component 3 is located in the atomizing chamber 210. The driving component 3 can push the atomizing matrix 4 in the atomizing chamber 210 to move along the plugging direction through the pushing member 33, that is, it can push the atomizing section 41 of the atomizing matrix 4 to move relative to the heating chamber 211, so that after the atomizing sections 41 of different lengths are inserted into the atomizing chamber 210, especially when the atomizing section 41 is longer than the heating chamber 211, the pushing member 33 is used to realize the sequential heating of the entire area of ​​the atomizing section 41, which can avoid the situation that the atomizing section 41 is too long and some areas cannot be heated; with such a configuration, the present aerosol generating device can adapt to the atomizing matrix 4 of the atomizing section 41 of different lengths;

[0060] Furthermore, by driving the driving assembly 3, different areas of the atomization section 41 can be heated in sequence, which is beneficial to improving the smoking taste.

The push rod 324 is parallel to the screw 321.

[0063] When the driving member 31 drives the screw rod 321 to rotate, the screw rod 321 will drive the slider 323 and the push rod 324 to move along the axial direction of the push rod 324 , thereby pushing the atomization matrix 4 to move axially in the atomization chamber 210 .
