[0038] In this document, the terms "first", "second", etc. are used only to distinguish one object from another, and do not necessarily have any temporal or technical meaning. The terms "connect", "couple", etc. mean a direct or indirect connection (coupling) unless otherwise stated.

[0039] Embodiment One:

[0040] Referring to FIGS. 1-5, an embodiment of the application provides a heating non-combustion atomization device 100, which includes a main machine 10, an air nozzle 20, and a cartridge 30. The main machine 10 has a mounting position 11 and an air outlet passage 12. The mounting position 11 penetrates at least one side wall of the main machine 10. One end of the air outlet passage 12 is in communication with the mounting position 11. The air nozzle 20 is connected to the main machine 10 and is in communication with the other end of the air outlet passage 12. Thus, the air outlet passage 12 is in communication with the air nozzle 20 and the mounting position 11. The air nozzle 20 can be fixedly connected to the main machine 10 or detachably connected.

[0041] The cartridge 30 is movably connected or detachably connected to the mounting position 11. The cartridge 30 is provided with a receiving cavity 31 and an opening 32 in communication with the receiving cavity 31. The receiving cavity 31 is used to accommodate a columnar smoking substrate 200. The opening 32 is used at least for the smoking substrate 200 to pass through to enter or exit the receiving cavity 31. That is, the smoking substrate 200 can be inserted into or taken out of the receiving cavity 31 through the opening 32.

[0042] Referring to FIG. 1, FIG. 3 and FIG. 5, the accommodating cavity 31 has a closed state and an open state; the cartridge 30 can be loaded into or detached from the installation position 11 from the side of the main machine 10, so as to switch the accommodating cavity 31 between the closed state and the open state. When the accommodating cavity 31 is in the closed state, the cartridge 30 is installed in the installation position 11, and the opening 32 is connected and communicated with the air outlet channel 12; when the accommodating cavity 31 is in the open state, the cartridge 30 is at least partially detached from the installation position 11, so that the opening 32 is exposed to the main machine 10.

[0043] That is, when the accommodating cavity 31 is in the closed state, the cartridge 30 is placed in the installation position 11, the opening 32 of the cartridge 30 is connected and communicated with the air outlet channel 12, the accommodating cavity 31 is connected with the air nozzle 20, and the aerosol generated by heating the smoking substrate 200 in the accommodating cavity 31 can flow to the air nozzle 20 through the opening 32 and the air outlet channel 12 in sequence, so as to realize the outflow of the aerosol from the air nozzle 20. When the accommodating cavity 31 is in the open state, the cartridge 30 is at least partially detached from the installation position 11, and the opening 32 is exposed to the main machine 10. At this time, the old smoking substrate 200 can be taken out through the exposed opening 32, and the new smoking substrate 200 can be loaded, so as to realize the replacement of the smoking substrate 200, and the empty accommodating cavity 31 can also be cleaned through the exposed opening 32.

[0044] By using the above technical scheme, the cylindrical smoking substrate 200 is accommodated in the accommodating cavity 31, and the length of the smoking substrate 200 is greatly shortened relative to the entire aerosol product, so that the height of the accommodating cavity 31 does not need to be set too high, thereby being beneficial to the cleaning of the accommodating cavity 31. Moreover, when the accommodating cavity 31 is in the open state, the cartridge 30 is at least partially detached from the installation position 11, so that the cartridge 30 is at least partially exposed to the main machine 10, which is beneficial to the separate cleaning of the cartridge 30. In addition, by using the heating non-combustion atomization equipment 100, only the smoking substrate 200 needs to be replaced, and other components except the smoking substrate 200 do not need to be replaced, thereby avoiding waste and reducing cost. Therefore, the heating non-combustion atomization equipment 100 provided in the embodiment is convenient to clean, improves the user experience, avoids waste, and reduces cost.

[0045] In an embodiment, the height of the accommodating cavity 31 is set to 3mm-20mm. In some embodiments, the height of the accommodating cavity 31 can be set to 3mm, 5mm, 7mm, 9mm, 11mm, 13mm, 15mm, 17mm, 19mm, 20mm, etc. The height of the smoking substrate 200 for generating aerosol is usually set to 5mm-18mm, and the height of the accommodating cavity 31 is set to 3mm-20mm, so that the accommodating cavity 31 can accommodate the smoking substrate 200 and can only accommodate the smoking substrate 200.

[0046] In an embodiment, the air nozzle 20 is provided with a filtering component and / or a temperature reducing component (not shown in the figure). The aerosol flowing through the filtering component can be filtered, and the aerosol flowing through the temperature reducing component can be cooled to avoid scalding the user, thus improving the user's experience.

[0047] In an embodiment, the smoking substrate 200 is fitted into the accommodating cavity 31 in an interference fit, i.e., the inner wall of the accommodating cavity 31 interferes with the outer periphery of the smoking substrate 200, thus improving the stability of the smoking substrate 200 in the accommodating cavity 31. When this technical solution is adopted, the user can use a tool to remove the old smoking substrate 200, such as a pair of tweezers, which is used to clamp the smoking substrate 200 and then pull out the smoking substrate 200 in the accommodating cavity 31 from the opening 32. It can be understood that in other embodiments, the inner wall of the accommodating cavity 31 and the outer periphery of the smoking substrate 200 can also have a gap, in which case the old smoking substrate 200 can be removed by using a tool, or the direction of the cartridge 30 can be changed so that the opening 32 faces downward, and the smoking substrate 200 can be automatically separated from the accommodating cavity 31 under the action of gravity.

[0048] Please refer to FIGS. 6 and 7, the cartridge 30 includes a cartridge body 33 and a protruding structure 34, the cartridge body 33 is provided with the accommodating cavity 31 and the opening 32, the protruding structure 34 is arranged on the inner wall of the accommodating cavity 31, and the protruding structure 34 forms a taking and placing gap 35 that communicates with the opening 32. By arranging the taking and placing gap 35, when the old smoking substrate 200 is removed by using a tool, part of the tool can be inserted into the taking and placing gap 35, and the other part is inserted into the smoking substrate 200, which is more conducive to removing the smoking substrate 200 than the technical solution in which the entire tool is inserted into the smoking substrate 200.

[0049] Please refer to FIGS. 6 and 7, the protruding structure 34 includes a plurality of protruding strips 341, the plurality of protruding strips 341 are arranged at intervals around the circumference of the accommodating cavity 31, and the taking and placing gap 35 is formed between adjacent protruding strips 341. In this way, the circumference of the smoking substrate 200 has a plurality of taking and placing gaps 35, improving the convenience of removing the smoking substrate 200. In some embodiments, the protruding strips 341 can extend linearly along the height direction of the accommodating cavity 31, or can extend along the height direction of the accommodating cavity 31 in a curved manner. It can be understood that in other embodiments, the protruding structure 34 can also be arranged in other forms, such as being arranged as a protruding rib that extends along the height direction of the accommodating cavity 31 in a spiral manner.

[0050] Referring to FIG. 8, the accommodation cavity 31 is coaxially arranged with the opening 32, and the accommodation cavity 31 is axially provided with at least two accommodation sections 311, and the protruding structure 34 is arranged on the inner wall of the accommodation section 311 of the accommodation cavity 31 close to the opening 32. The protruding structure 34 is arranged on the inner wall of the accommodation section 311 of the accommodation cavity 31 close to the opening 32, so that the taking and placing gap 35 is in communication with the opening 32, and only a part of the tool can be inserted into the taking and placing gap 35. Of course, in some embodiments, as an alternative implementation, the protruding structure 34 can also be arranged on the inner wall of all the accommodation sections 311.

[0051] In an embodiment, the inner side of the protruding structure 34 is flush with the inner wall of the accommodation section 311 without the protruding structure 34. In some embodiments, the inner diameter of the accommodation section 311 with the protruding structure 34 is greater than the inner diameter of the accommodation section 311 without the protruding structure 34, and the accommodation section 311 without the protruding structure 34 is in interference fit with the smoking substrate 200. By making the inner side of the protruding structure 34 flush with the inner wall of the accommodation section 311 without the protruding structure 34, the protruding structure 34 and the accommodation section 311 without the protruding structure 34 are both in interference fit with the smoking substrate 200, so that the entire smoking substrate 200 is accommodated in the accommodation cavity 31 in interference fit. Of course, in other embodiments, the inner side of the protruding structure 34 can also be arranged not flush with the inner wall of the accommodation section 311 without the protruding structure 34.

[0052] In an embodiment, the caliber of the opening 32 is 7.5mm-9mm. In some embodiments, the caliber of the opening 32 can be set to 7.5mm, 7.8mm, 8mm, 8.3mm, 8.6mm, 8.8mm, 9mm, etc. The diameter of the smoking substrate 200 is usually set to 6.5mm-7.5mm, and by setting the caliber of the opening 32 to 7.5mm-9mm, it can be ensured that the smoking substrate 200 can pass through the opening 32 into the accommodation cavity 31 or exit from the accommodation cavity 31.

[0053] In an embodiment, the diameter of the accommodation section 311 without the protruding structure 34 among the at least two accommodation sections 311 is 5mm-7.3mm. In some embodiments, the diameter of the accommodation section 311 without the protruding structure 34 can be set to 5mm, 5.3mm, 5.6mm, 5.8mm, 6mm, 6.3mm, 6.7mm, 7mm, 7.3mm, etc. The diameter of the smoking substrate 200 is usually set to 6.5mm-7.5mm, and by setting the diameter of the accommodation section 311 without the protruding structure 34 to 5mm-7.3mm, which is smaller than the diameter of the smoking substrate 200, so that the accommodation section 311 without the protruding structure 34 can be in interference fit with the smoking substrate 200.

[0054] Referring to FIG. 2, FIG. 3 and FIG. 5, the installation site 11 comprises a notch 111 formed on the side of the main body 10, which penetrates at least two sides of the main body 10, and the opening 32 of the cartridge 30 is located outside the notch 111 when the accommodation cavity 31 is in an open state. In this embodiment, the main body 10 comprises a first slot wall 13, a second slot wall 14 and a third slot wall 15, the first slot wall 13 and the second slot wall 14 are oppositely arranged, and the third slot wall 15 is connected between the first slot wall 13 and the second slot wall 14. The first slot wall 13, the second slot wall 14 and the third slot wall 15 enclose the notch 111 of the installation site 11, which penetrates three sides of the main body 10, and the air outlet channel 12 is formed on the first slot wall 13 near one end of the installation site 11.

[0055] In some embodiments, the cartridge 30 can be movably connected or detachably connected to the installation site 11 by providing a connecting assembly between at least one of the first slot wall 13, the second slot wall 14 and the third slot wall 15 and the cartridge 30. For example, the third slot wall 15 is provided with a first magnetic attraction member 18, and the cartridge 30 is provided with a second magnetic attraction member (not shown in the figure) magnetically attracted to the first magnetic attraction member 18. The cartridge 30 is magnetically attracted to the first magnetic attraction member 18 and the second magnetic attraction member to be detachably connected to the installation site 11. Of course, the cartridge 30 and the installation site 11 can also be detachably connected in other ways, such as one of the cartridge 30 and the installation site 11 being provided with a sliding block and the other being provided with a sliding groove slidably matched with the sliding block to achieve detachable connection by sliding the sliding block in the sliding groove. In addition, the cartridge 30 and the installation site 11 can also be movably connected by providing an eccentric rotating shaft and a rotating groove.

[0056] Referring to FIG. 5 and FIG. 6, the cartridge 30 also has a first air inlet 36 for communicating the outside of the cartridge 30 with the accommodation cavity 31. By providing the first air inlet 36, gas outside the cartridge 30 can enter the accommodation cavity 31, so that the aerosol in the accommodation cavity 31 can flow out with the gas flow.

[0057] In an embodiment, the first air inlet 36 is formed on the side wall of the cartridge 30, i.e. the first air inlet 36 is located on the side of the accommodation cavity 31. In use of the heating non-combustion atomization device 100, the opening 32 is usually located above the accommodation cavity 31 so that the smoking substrate 200 is not easy to fall out of the accommodation cavity 31 when accommodated in the accommodation cavity 31, and the aerosol generated by the smoking substrate 200 can flow upward and out of the accommodation cavity 31. In this embodiment, by forming the first air inlet 36 on the side wall of the cartridge 30, when the accommodation cavity 31 is in a closed state, gas can enter the accommodation cavity 31 from the side of the heating non-combustion atomization device 100 through the notch 111 and the first air inlet 36, and then flow to the air outlet 20 through the opening 32, and the aerosol in the accommodation cavity 31 can be sucked out to the air outlet 20 together with the gas.

[0058] In an embodiment, the first air inlet 36 is arranged on both sides of the cartridge 30, so as to increase the amount of air entering the accommodating cavity 31. Of course, as an alternative embodiment, the first air inlet 36 can also be arranged on only one side of the cartridge 30.

[0059] Referring to FIGS. 6 and 7, the cartridge 30 further comprises a heat insulation layer 37, at least one heat insulation layer 37 being arranged on the side of the cartridge body 33 opposite to the accommodating cavity 31, and / or at least one heat insulation layer 37 being arranged on the side of the cartridge body 33 facing the accommodating cavity 31. By arranging the heat insulation layer 37, on the one hand, the heat loss in the accommodating cavity 31 can be prevented from affecting the heating of the smoking substrate 200, and on the other hand, the user can be prevented from being scalded when switching the cartridge 30 from the closed state to the open state.

[0060] In an embodiment, the heat-not-burn atomization device 100 further comprises a heating assembly (not shown in the drawings), which is used to heat the smoking substrate 200 in the accommodating cavity 31 to generate aerosol. The heating assembly can be arranged in the cartridge 30, arranged in the main machine 10, or partially arranged in the cartridge 30 and partially arranged in the main machine 10. According to different arrangements, the heating assembly can be heated by resistance, electromagnetic induction, microwave, infrared, ultrasonic, or any other heating method. In addition, the heating assembly can be heated by circumferential heating, hot air flow, or both.

[0061] Referring to FIGS. 1 and 2, the present application further provides an aerosol generating system, which comprises the smoking substrate 200 and the heat-not-burn atomization device 100 described above; the smoking substrate 200 is detachably accommodated in the accommodating cavity 31, and the heat-not-burn atomization device 100 is used to heat the smoking substrate 200 in the accommodating cavity 31 in the closed state to generate aerosol.

[0062] By using the heat-not-burn atomization device 100 described above, the smoking substrate 200 can be replaced through the opening 32, and the cartridge 30 is easy to clean and has low use cost.

[0063] Embodiment Two:

[0064] The heat-not-burn atomization device 100 and the aerosol generating system provided in the present embodiment mainly differ from those in Embodiment One in the arrangement position of the first air inlet 36, specifically, in Embodiment One, the first air inlet 36 is arranged on the side wall of the cartridge 30, while in the present embodiment, the first air inlet 36 is arranged opposite to the opening 32.

[0065] Referring to FIG. 9 and FIG. 10, the host 10 further comprises a second air inlet 16 and an air inlet channel 17 communicating with the second air inlet 16, and when the accommodating cavity 31 is in the closed state, the end of the air inlet channel 17 away from the second air inlet 16 is docked and communicated with the first air inlet 36. The opening 32 is arranged above the cartridge 30, and the first air inlet 36 is arranged opposite to the opening 32, so that the first air inlet 36 is below the cartridge 30. The end of the air inlet channel 17 away from the second air inlet 16 is arranged on the second slot wall 14, so that it can be docked and communicated with the first air inlet 36 when the accommodating cavity 31 is in the closed state. The second air inlet 16 can be arranged at any position of the host 10, such as the bottom or side of the host 10.

[0073] Embodiment Four:

[0074] The main difference between the heating non-combustion atomization device 100 and the aerosol generating system provided by the present embodiment and Embodiments One to Three lies in the number of accommodating cavities 31 provided by the cartridge 30, which is embodied in that in Embodiments One to Three, the cartridge 30 is provided with one accommodating cavity 31, while in the present embodiment, the cartridge 30 is provided with at least two accommodating cavities 31.

[0075] Referring to FIG. 13 to FIG. 15, the cartridge 30 has at least two accommodating cavities 31 and at least two openings 32, and the accommodating cavities 31 and the openings 32 correspond to each other. When the cartridge 30 is installed in the installation position 11, each accommodating cavity 31 can selectively communicate with the air outlet channel 12 through the opening 32 communicating therewith, that is, only the smoking substrate 200 in one of the accommodating cavities 31 is heated to generate an aerosol and flow to the gas nozzle 20.

[0076] By providing at least two accommodating cavities 31, at least two smoking substrates 200 can be loaded or replaced in the cartridge 30 at one time, and it is not necessary to replace a new smoking substrate 200 after using up one smoking substrate 200 to continue using. In this way, the frequency of replacing the smoking substrate 200 is reduced, the time difference between two times of replacing the smoking substrate 200 is prolonged, and the user's experience is greatly improved.

[0077] In some embodiments, the accommodating cavities 31 can be provided with two, three, four, five or more accommodating cavities 31, and the arrangement of the plurality of accommodating cavities 31 is not limited, which can be arranged in a straight line, arranged in a curve, or arranged in a ring shape. In an embodiment, the plurality of accommodating cavities 31 are arranged in a ring shape along the central axis of the cartridge 30.

[0078] In addition to the above differences, the heating non-combustion atomization device 100 and other components provided by the present embodiment can be designed with reference to embodiments one to three, and will not be described in detail here.
