[0047] See also Figure 1-13 As shown, according to one aspect of the present application, a heating module 100 is provided. The heating module 100 is constructed to include a first heating chamber 11 and a second heating chamber 31. The first heating chamber 11 has a first opening 111, and the second heating chamber 31 has a second opening 311. The first heating chamber 11 and the second heating chamber 31 are arranged back to back, so that the dimension of the heating module 100 in the direction perpendicular to the first heating chamber 11 and pointing to the second heating chamber 31 is compressed, thereby making the aerosol generating device 1000 including the heating module 100 more convenient for the user to hold.

[0048] In addition, by arranging the first heating chamber 11 and the second heating chamber 31 back to back, so that the first opening 111 is opposite to the second opening 311, when one of the first heating chamber 11 and the second heating chamber 31 is in use, the opening of the used heating chamber faces upward, and the opening of the unused heating chamber faces downward, thereby effectively preventing foreign matter from falling into the unused heating chamber.

[0049] Furthermore, the heating module 100 includes a first heating cavity 10 and a second heating cavity 30 , wherein the first heating cavity 10 is configured to form a first heating chamber 11 , and the second heating cavity 30 is configured to form a second heating chamber 31 .

[0052] Furthermore, the first heating chamber 10 and the second heating chamber 30 heat the aerosol-generating article 2000 in different ways. Different heating methods for the aerosol-generating article 2000 can provide different user experiences. Therefore, users can choose a heating method based on their preferences. Based on this, the heating module 100 provided in this embodiment can also satisfy users' need to experience the taste of aerosols produced by different heating methods, eliminating the need for users to purchase multiple aerosol generating devices 1000.

[0053] Please refer to Figure 3-7 As shown, in some embodiments, the first heating chamber 10 is configured to heat the aerosol-generating article 2000 circumferentially.

[0054] Please refer to Figure 3-8 As shown, the first heating chamber 10 includes a first tube 12, a first receiving seat 13, and a second tube 14. The first tube 12 has a first opening 111 and a third opening 112 opposite each other. The first receiving seat 13 is connected to an end of the first tube 12 near the third opening 112. The first receiving seat 13 and the first tube 12 together form the first heating chamber 11.

[0055] Furthermore, the first receiving seat 13 is constructed to form a receiving hole 131. The receiving hole 131 includes a third sub-hole 1311 and a fourth sub-hole 1312 that communicate with each other. A second limiting surface 1313 is formed at the connection point between the third sub-hole 1311 and the fourth sub-hole 1312. The end of the first tube 12 closest to the third opening 112 is inserted into the third sub-hole 1311 and abuts against the second limiting surface 1313.

[0056] In some embodiments, the first tube 12 is a heating tube, and the first tube 12 is used to circumferentially heat the aerosol-generating article 2000 inserted into the first heating chamber 11 to generate aerosol.

[0057] The second tube 14 is disposed outside the first tube 12. One end of the second tube 14 near the third opening 112 is sealedly connected to the first receiving seat 13. One end of the second tube 14 near the first opening 111 is sealedly connected to the first tube 12.

[0058] Furthermore, the first receiving seat 13 is at least partially inserted into the third opening 112. A first sealing ring 15 is provided between the second tube 14 and the first receiving seat 13 to seal the third opening 112. A first stopper 141 is formed at one end of the second tube 14 near the first opening 111. The first stopper 141 is configured to form a third limiting surface 1411. The first tube 12 is sandwiched between the third limiting surface 1411 and the second limiting surface 1313.

[0059] Furthermore, the first receiving seat 13 and the second tube 14 are made of a high-temperature resistant material with a thermal conductivity of less than 0.5 W / m*K and a certain degree of hardness. Polyetheretherketone (PEEK) is preferred, as it is heat-resistant and can withstand temperatures of 200-400°C. Furthermore, parts produced using PEEK have stable structural dimensions and are easy to mass-produce.

[0060] When the first tube 12 is sandwiched between the third limiting surface 1411 and the second limiting surface 1313, the end of the first tube 12 near the first opening 111 is interference-fitted with the second tube 14, thereby achieving a sealed connection between the first tube 12 and the second tube 14. The end of the first tube 12 near the third opening 112 is interference-fitted with the first receiving seat 13, thereby achieving a sealed connection between the first tube 12 and the first receiving seat 13.

[0061] The first tube body 12 , the first receiving seat 13 and the second tube body 14 together form a heat preservation chamber 16 . The heat preservation chamber 16 is located on the outer peripheral side of the first heating chamber 11 .

[0062] When the first heating chamber 11 emits heat to the outside, the emitted heat is absorbed by the insulation chamber 16, preventing the heat emitted by the first heating chamber 11 from being directly absorbed by the outside world, causing the temperature of the insulation chamber 16 to rise, thereby reducing the temperature difference between the insulation chamber 16 and the first heating chamber 11, and thereby achieving the insulation of the first heating chamber 11 by the insulation chamber 16.

[0063] Furthermore, the outer portion of the first tube body 12 , the inner wall of the second tube body 14 and the first receiving seat 13 are jointly constructed to form a heat preservation chamber 16 .

[0064] Please refer to Figure 6As shown, in some embodiments, the first heating chamber 10 further includes a third tube 17. The third tube 17 is disposed outside the second tube 14. The inner sidewall of the third tube 17 and the outer sidewall of the second tube 14 together form a first air flow channel 21. The first air flow channel 21 includes a first air inlet 211 and a first air outlet 212. The first air inlet 211 is adjacent to the first opening 111, and the first air outlet 212 is adjacent to the third opening 112, and both are connected to the first heating chamber 11.

[0065] By arranging the first airflow channel 21 outside the second tube 14, the heat from the first heating chamber 11 is absorbed by the heat-insulating chamber 16, thereby preheating the gas in the first airflow channel 21. The preheated gas enters the first heating chamber 11, thereby more fully heating the aerosol-forming substrate in the first heating chamber 11. This prevents unpreheated gas from directly entering the first heating chamber 11 and affecting the heating efficiency of the aerosol-generating article 2000 housed therein.

[0079] Compared with the arrangement in which the first heating cavity 10 and the second heating cavity 30 are installed separately, the first heating cavity 10 and the second heating cavity 30 are connected into one by the connecting member 40, which facilitates the installation of the heating module 100 and other components, making the installation of the heating module 100 more efficient.

[0080] Furthermore, when the heating module 100 is installed on the aerosol generating device 1000 , the connecting member 40 is installed on the housing 200 of the aerosol generating device 1000 , thereby achieving the installation of the heating module 100 .
