[0046] Embodiment 1:

[0047] Please refer to Figures 1 to 5 , an atomizing device 100 for non-combustion heating provided by an embodiment of the present utility model includes a main body 10, a mouthpiece 20, and a cartridge 30. The main body 10 has a mounting position 11 and an air outlet channel 12. The mounting position 11 penetrates at least one side wall of the main body 10, and one end of the air outlet channel 12 communicates with the mounting position 11. The mouthpiece 20 is connected to the main body 10 and communicates with the other end of the air outlet channel 12. Thus, the air outlet channel 12 communicates the mouthpiece 20 and the mounting position 11. Among them, the mouthpiece 20 can be fixedly connected to the main body 10 or detachably connected.

[0048] 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 communicating with the receiving cavity 31. The receiving cavity 31 is used to receive a columnar smoking substrate 200, and the opening 32 is at least used 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.

[0049] Please refer to Figure 1 ,Figure 3 and Figure 5 The accommodation cavity 31 has a closed state and an open state; the cartridge 30 can be loaded into the installation position 11 from the side of the main body 10 or detached from the installation position 11, so as to switch the accommodation cavity 31 between the closed state and the open state. When the accommodation cavity 31 is in the closed state, the cartridge 30 is installed in the installation position 11, and the opening 32 is docked and communicated with the air outlet channel 12; when the accommodation 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 outside the main body 10.

[0050] That is to say, when the accommodation 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 docked and communicated with the air outlet channel 12, the accommodation cavity 31 is communicated with the mouthpiece 20, and the aerosol generated by heating the smoke generating matrix 200 located in the accommodation cavity 31 can sequentially pass through the opening 32 and the air outlet channel 12 and flow to the mouthpiece 20, so as to realize the outflow of the aerosol from the mouthpiece 20. When the accommodation 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 outside the main body 10. At this time, the old smoke generating matrix 200 can be taken out through the exposed opening 32, and a new smoke generating matrix 200 can be loaded, so as to realize the replacement of the smoke generating matrix 200. The empty accommodation cavity 31 can also be cleaned through the exposed opening 32.

[0051] By adopting the above technical solution, by arranging the accommodation cavity 31 to accommodate the columnar smoke generating matrix 200, and the length of the smoke generating matrix 200 is greatly shortened relative to the whole aerosol product, so the height of the accommodation cavity 31 does not need to be set very high, which is beneficial to cleaning the accommodation cavity 31. And when the accommodation cavity 31 is in the open state, the cartridge 30 is at least partially detached from the installation position 11, so that at least part of the cartridge 30 is exposed outside the main body 10, which is beneficial to cleaning the cartridge 30 separately. In addition, by adopting the heat-not-burn atomization device 100, only the smoke generating matrix 200 needs to be replaced, and other components except the smoke generating matrix 200 do not need to be replaced, which avoids waste and reduces the cost. Therefore, the heat-not-burn atomization device 100 provided in this embodiment is convenient to clean, improves the user experience, and also avoids waste and reduces the cost.

[0052] In one embodiment, the height of the accommodation cavity 31 is set to 3 mm to 20 mm. Specifically, the height of the accommodation cavity 31 can be set to 3 mm, 5 mm, 7 mm, 9 mm, 11 mm, 13 mm, 15 mm, 17 mm, 19 mm, 20 mm, etc. The height of the smoke generating matrix 200 used to generate the aerosol is usually set to 5 mm to 18 mm. By setting the height of the accommodation cavity 31 to 3 mm to 20 mm, the accommodation cavity 31 can accommodate the smoke generating matrix 200 and can only accommodate the smoke generating matrix 200.

[0053] In one embodiment, a filtering component and / or a cooling component (not shown in the figure) are provided inside the mouthpiece 20. Through the filtering component, the aerosol flowing through can be filtered. By providing the cooling component, the aerosol flowing through can be cooled to avoid scalding the user. Thus, the user experience can be improved.

[0054] In one embodiment, the smoke generating matrix 200 is press-fitted into the accommodating cavity 31, that is, the inner wall of the accommodating cavity 31 is press-fitted with the outer periphery of the smoke generating matrix 200, so as to improve the stability of the smoke generating matrix 200 placed in the accommodating cavity 31. When adopting this technical solution, the user can use a tool to take out the old smoke generating matrix 200, such as tweezers. By clamping the smoke generating matrix 200 with the tweezers, and then pulling out the smoke generating matrix 200 in the accommodating cavity 31 from the opening 32. It can be understood that in other embodiments, it is also possible that there is a gap between the inner wall of the accommodating cavity 31 and the outer periphery of the smoke generating matrix 200. At this time, the old smoke generating matrix 200 can be taken out with the help of a tool, or the direction of the cartridge 30 can be changed so that the opening 32 faces downward, and the smoke generating matrix 200 can automatically separate from the accommodating cavity 31 under the action of gravity.

[0055] Please refer to Figure 6 and Figure 7 , the cartridge 30 includes a cartridge body 33 and a protruding structure 34. The cartridge body 33 is provided with an accommodating cavity 31 and an opening 32. The protruding structure 34 is provided on the inner wall of the accommodating cavity 31, and the protruding structure 34 forms a placing and taking gap 35 communicating with the opening 32. By providing the placing and taking gap 35, when taking out the old smoke generating matrix 200 with the help of a tool, a part of the tool can be inserted into the placing and taking gap 35, and the other part can be inserted into the smoke generating matrix 200. Compared with the technical solution where the whole tool is inserted into the smoke generating matrix 200, it is more beneficial to take out the smoke generating matrix 200.

[0056] Please refer to Figure 6 and Figure 7 , the protruding structure 34 includes a plurality of convex strips 341. The plurality of convex strips 341 are arranged at intervals around the circumference of the accommodating cavity 31, and a placing and taking gap 35 is formed between adjacent convex strips 341. In this way, there are a plurality of placing and taking gaps 35 around the circumference of the smoke generating matrix 200, improving the convenience of taking out the smoke generating matrix 200. Specifically, the convex strips 341 can extend linearly along the height direction of the accommodating cavity 31, or can extend curvilinearly along the height direction of the accommodating cavity 31. It can be understood that in other embodiments, the protruding structure 34 can also be set in other forms, such as setting a convex rib, and the convex rib extends spirally along the height direction of the accommodating cavity 31.

[0057] Please refer to Figure 8, the accommodation cavity 31 and the opening 32 are coaxially arranged. The accommodation cavity 31 is provided with at least two accommodation segments 311 along the axial direction, and the protruding structure 34 is arranged on the inner wall of the accommodation segment 311 of the accommodation cavity 31 close to the opening 32. By arranging the protruding structure 34 on the inner wall of the accommodation segment 311 of the accommodation cavity 31 close to the opening 32, the access gap 35 can be communicated with the opening 32, so that a part of the tool can be inserted into the access gap 35. Of course, in specific applications, as an alternative implementation, it is also possible to arrange the protruding structure 34 on the inner walls of all the accommodation segments 311.

[0058] In one embodiment, the inner side of the protruding structure 34 is flush with the inner wall of the accommodation segment 311 without the protruding structure 34. Specifically, when implemented, the inner diameter of the accommodation segment 311 provided with the protruding structure 34 is larger than the inner diameter of the accommodation segment 311 without the protruding structure 34. The accommodation segment 311 without the protruding structure 34 is in interference fit with the smoke generating matrix 200. By making the inner side of the protruding structure 34 flush with the inner wall of the accommodation segment 311 without the protruding structure 34, both the protruding structure 34 and the accommodation segment 311 without the protruding structure 34 are in interference fit with the smoke generating matrix 200, so that the entire smoke generating matrix 200 is accommodated in the accommodation cavity 31 in an interference fit manner. Of course, in other embodiments, it is also possible that the inner side of the protruding structure 34 is not flush with the inner wall of the accommodation segment 311 without the protruding structure 34.

[0059] In one embodiment, the diameter of the opening 32 is 7.5 mm to 9 mm. Specifically, when implemented, the diameter of the opening 32 can be set to 7.5 mm, 7.8 mm, 8 mm, 8.3 mm, 8.6 mm, 8.8 mm, 9 mm, etc. The diameter of the smoke generating matrix 200 is usually set to 6.5 mm to 7.5 mm. By setting the diameter of the opening 32 to 7.5 mm to 9 mm, it can be ensured that the smoke generating matrix 200 can pass through the opening 32 and enter the accommodation cavity 31 or exit from the accommodation cavity 31.

[0060] In one embodiment, the diameter of the accommodation segment 311 without the protruding structure 34 among at least two accommodation segments 311 is 5 mm to 7.3 mm. Specifically, when implemented, the diameter of the accommodation segment 311 without the protruding structure 34 can be set to 5 mm, 5.3 mm, 5.6 mm, 5.8 mm, 6 mm, 6.3 mm, 6.7 mm, 7 mm, 7.3 mm, etc. The diameter of the smoke generating matrix 200 is usually set to 6.5 mm to 7.5 mm. By setting the diameter of the accommodation segment 311 without the protruding structure 34 to 5 mm to 7.3 mm, which is smaller than the diameter of the smoke generating matrix 200, the accommodation segment 311 without the protruding structure 34 can be in interference fit with the smoke generating matrix 200.

[0061] Please refer to Figure 2 , Figure 3 andFigure 5 , the installation position 11 includes a notch 111 formed on the side of the main body 10, passing through at least two side surfaces of the main body 10. When the accommodation cavity 31 is in an open state, the opening 32 of the magazine 30 is located outside the notch 111. In this embodiment, the main body 10 includes a first groove wall 13, a second groove wall 14, and a third groove wall 15. The first groove wall 13 and the second groove wall 14 are oppositely arranged, and the third groove wall 15 is connected between the first groove wall 13 and the second groove wall 14. The first groove wall 13, the second groove wall 14, and the third groove wall 15 enclose the notch 111 of the installation position 11. The installation position 11 passes through three side surfaces of the main body 10, and one end of the air outlet channel 12 close to the installation position 11 is opened on the first groove wall 13.

[0062] During specific implementation, a connection component can be arranged between at least one of the first groove wall 13, the second groove wall 14, and the third groove wall 15 and the magazine 30, so that the magazine 30 is movably connected to the installation position 11 or detachably connected to the installation position 11. Exemplarily, a first magnetic component 18 is arranged on the third groove wall 15, and the magazine 30 is provided with a second magnetic component (not shown in the figure) magnetically adsorbed and cooperated with the first magnetic component 18. The magazine 30 is detachably connected and installed at the installation position 11 through the magnetic adsorption of the first magnetic component 18 and the second magnetic component. Of course, the magazine 30 and the installation position 11 can also be detachably connected in other ways. For example, a slider is arranged on one of the magazine 30 and the installation position 11, and a sliding groove slidably matched with the slider is arranged on the other. The detachable connection is realized through the sliding cooperation of the slider and the sliding groove. In addition, the magazine 30 and the installation position 11 can also be movably connected by arranging an eccentric rotating shaft and a rotating groove.

[0063] Please refer to Figure 5 and Figure 6 , the magazine 30 further has a first air inlet 36, and the first air inlet 36 is used to communicate the outside of the magazine 30 and the accommodation cavity 31. By arranging the first air inlet 36, the gas outside the magazine 30 can enter the accommodation cavity 31, so that the aerosol in the accommodation cavity 31 can flow out along with the air flow.

[0064] In one embodiment, the first air inlet 36 is formed in the side wall of the cartridge 30, that is, the first air inlet 36 is located at the side of the accommodation cavity 31. When the heat-not-burn atomization device 100 is in use, the opening 32 is usually located above the accommodation cavity 31, so that the smoke-generating substrate 200 is placed in the accommodation cavity 31 and is not easily separated from the accommodation cavity 31, and the aerosol generated by the smoke-generating substrate 200 can flow upward and out of the accommodation cavity 31. In this embodiment, by forming the first air inlet 36 in 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 heat-not-burn atomization device 100 through the notch 111 and the first air inlet 36, and then flow to the mouthpiece 20 through the opening 32. The aerosol in the accommodation cavity 31 can be sucked out to the mouthpiece 20 together with the gas.

[0065] In one embodiment, the first air inlets 36 are provided on both opposite sides of the cartridge 30, so that the amount of air entering the accommodation cavity 31 can be increased. Of course, as an alternative implementation, it is also possible to provide the first air inlet 36 only on one side of the cartridge 30.

[0066] Please refer to Figure 6 and Figure 7 , the cartridge 30 further includes a heat insulation layer 37. At least one layer of heat insulation layer 37 is provided on the side of the cartridge body 33 facing away from the accommodation cavity 31, and / or at least one layer of heat insulation layer 37 is provided on the side of the cartridge body 33 facing the accommodation cavity 31. By providing the heat insulation layer 37, on the one hand, it can prevent the heat loss in the accommodation cavity 31 from affecting the heating of the smoke-generating substrate 200, and on the other hand, when the user switches the cartridge 30 from the closed state to the open state, it can prevent the user from being scalded when contacting the cartridge 30.

[0067] In one embodiment, the heat-not-burn atomization device 100 further includes a heating component (not shown in the figure). The heating component is used to heat the smoke-generating substrate 200 in the accommodation cavity 31 to generate an aerosol. Among them, the heating component can be provided in the cartridge 30, can also be provided in the main body 10, or can be partially provided in the cartridge 30 and partially provided in the main body 10. And, according to different setting methods, the heating component can be heated by a resistance method, can also be heated by an electromagnetic induction method, and can also be heated by any one of microwave, infrared, ultrasonic and other heating methods. In addition, the heating component can adopt a circumferential heating method, can also adopt a hot air flow heating method, or can simultaneously adopt a circumferential heating and a hot air flow heating. It should be noted that the setting of the heating component is not limited here.

[0068] Please refer to Figure 1 and Figure 2The embodiment of the utility model also provides an aerosol generating system, including a smoking substrate 200 and the above-mentioned heat-not-burn atomizing device 100; the smoking substrate 200 is detachably accommodated in the accommodating cavity 31, and the heat-not-burn atomizing device 100 is used to heat the smoking substrate 200 in the accommodating cavity 31 in a closed state to generate an aerosol.

[0069] By adopting the above-mentioned heating without burning atomization device 100, the smoke-generating substrate 200 can be replaced through the opening 32, and the magazine 30 is easy to clean and has low use cost.

[0070] Embodiment 2:

[0071] The difference between the heat-not-burn atomization device 100 and the aerosol generating system provided in this embodiment and those in the first embodiment mainly lies in the different setting positions of the first air inlet 36, which is specifically reflected in that: in the first embodiment, the first air inlet 36 is opened on the side wall of the magazine 30; while in the present embodiment, the first air inlet 36 is arranged opposite to the opening 32.

[0072] See also Figure 9 and Figure 10 The host 10 further includes a second air inlet 16 and an air inlet channel 17 connected to the second air inlet 16. When the accommodating chamber 31 is in a closed state, the end of the air inlet channel 17 away from the second air inlet 16 is connected to and connected to the first air inlet 36. The opening 32 is provided above the magazine 30, and the first air inlet 36 is arranged opposite to the opening 32. Then, the first air inlet 36 is located below the magazine 30. The end of the air inlet channel 17 away from the second air inlet 16 is opened on the second groove wall 14, so that it can be connected to and connected to the first air inlet 36 when the accommodating chamber 31 is in a closed state. Among them, the second air inlet 16 can be opened at any part of the host 10, such as the bottom or side of the host 10.

[0073] In specific implementation, gas can enter the accommodating chamber 31 from the outside through the second air inlet 16, the air inlet channel 17 and the first air inlet 36, and flow to the air nozzle 20 through the accommodating chamber 31. The aerosol in the accommodating chamber 31 can flow to the air nozzle 20 along with the airflow.

[0074] In one embodiment, the diameter of the first air inlet 36 is smaller than that of the opening 32. In a specific application, the diameter of the first air inlet 36 is smaller than the diameter of the smoking substrate 200, so that the smoking substrate 200 will not be separated from the accommodating chamber 31 from the first air inlet 36.

[0075] In addition to the above differences, the heat-not-burn atomization device 100 and other components provided in this embodiment can be designed with reference to the first embodiment and will not be described in detail here.

[0077] The main difference between the heat-not-burn atomization device 100 and the aerosol generating system provided in this embodiment and those in the first embodiment lies in whether the cartridge 30 is provided with a first air inlet 36, specifically: in the first embodiment, the cartridge 30 is provided with a first air inlet 36; while in this embodiment, the cartridge 30 is not provided with a first air inlet 36.

[0078] Please refer to Figure 11 and Figure 12 , the main body 10 further includes a second air inlet 16 and an air intake passage 17 communicating with the second air inlet 16. One end of the air intake passage 17 far from the second air inlet 16 communicates with the air outlet passage 12. With such a setting, when the accommodating cavity 31 is in a closed state, the smoking substrate 200 is heated anaerobically in the accommodating cavity 31 to generate aerosol, and the gas flows from the outside through the second air inlet 16, the air intake passage 17 and the air outlet passage 12 to the mouthpiece 20, so as to generate a negative pressure environment with a pressure lower than that in the accommodating cavity 31 in the mouthpiece 20, thereby enabling the aerosol to flow to the mouthpiece 20. It can be understood that in another embodiment, it is also possible that one end of the air intake passage 17 far from the second air inlet 16 communicates with the mouthpiece 20. When adopting this technical solution, the gas directly flows from the outside through the second air inlet 16 and the air intake passage 17 to the mouthpiece 20.

[0079] Except for the above differences, the heat-not-burn atomization device 100 and other components provided in this embodiment can be designed with reference to the first embodiment, and details will not be described herein again.

[0080] Embodiment 4:

[0081] The main difference between the heat-not-burn atomization device 100 and the aerosol generating system provided in this embodiment and those in the first to third embodiments lies in the different number of accommodating cavities 31 provided in the cartridge 30, specifically: in the first to third embodiments, the cartridge 30 is provided with one accommodating cavity 31; while in this embodiment, the cartridge 30 is provided with at least two accommodating cavities 31.

[0082] Please refer to Figures 13 to 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 one by one. When the cartridge 30 is installed at the installation position 11, each accommodating cavity 31 can be selectively connected to the air outlet passage 12 through the corresponding opening 32, that is, only the smoking substrate 200 in one accommodating cavity 31 is heated to generate aerosol and flows to the mouthpiece 20.

[0083] By providing at least two accommodating cavities 31, at least two smoke-generating matrices 200 can be loaded into or replaced in the cartridge 30 at one time, without the need to replace a new smoke-generating matrix 200 after using up one smoke-generating matrix 200 to continue using. In this way, the frequency of replacing the smoke-generating matrix 200 is reduced, the time difference between two replacements of the smoke-generating matrix 200 is extended, and the user experience is greatly improved.

[0084] In specific implementation, the number of accommodating cavities 31 can be two, three, four, five, etc. The arrangement of multiple accommodating cavities 31 is not limited. They can be arranged in a straight line, in a curve, or in a circular arrangement. Preferably, multiple accommodating cavities 31 are arranged in a circular pattern along the central axis of the cartridge 30.

[0085] Except for the above differences, the heat-not-burn atomization device 100 and other components provided in this embodiment can be designed with reference to Embodiments 1 to 3, and will not be elaborated here.

[0086] The above uses specific examples to illustrate the present invention, which is only used to help understand the present invention and is not used to limit the present invention. For those skilled in the technical field to which the present invention pertains, based on the idea of the present invention, several simple deductions, deformations, or substitutions can also be made.
