[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] like Figure 1-4As shown, an aerosol generating device is used to heat a smokeable material so that the smokeable material generates an aerosol. The consumable product 200 containing the smokeable material is usually in the form of a cigarette, including a smokeable material 201 at the front end, a cooling structure 202 in the middle, and a filter structure 203 at the mouth end. The aerosol generating device 100 and the consumable product 200 of the smokeable material inserted therein constitute an aerosol generating system.

[0031] The aerosol generating device 100 includes a shell 1, which is composed of a front shell, a rear shell, an upper top cover 11 and a lower bottom cover 12. A sliding cover 13 and an insertion port 14 are provided on the top cover 11. When in use, the sliding cover 13 can be moved to expose the insertion port 14 so that the consumable 200 can be inserted. When not in use, the sliding cover 13 can cover the insertion port 14 to prevent foreign objects from entering.

[0032] The clamping portion 2 , the fixing seat 3 , the heater 4 , the heat insulation tube 5 , the sleeve 6 and the stopper 7 are sequentially arranged below the insertion port 14 .

[0033] During use, the consumable product 200 can be removably inserted into the aerosol generating device 100 through the clamping portion 2 and clamped by the clamping portion 2. The clamping portion 2 does not make thermal contact with the fixing seat 3 and the heater 4, thereby preventing the clamping portion 2 from heating up during use and then heating the clamped portion of the consumable product 200. Generally, when the consumable product 200 is fully inserted into the aerosol generating device 100, the clamping portion 2 clamps the non-smokable material part, such as the cooling structure 202 and / or the filtering structure 203. Since the aerosol smoke generated by the smokeable material 201 part has a high temperature and needs to be cooled by the cooling structure 202 and / or the filtering structure 203, if these parts are also heated by the hot clamping portion 2, the smoke entering the consumer's mouth will be too hot, affecting the smoking experience and effect.

[0034] The heater 4 is disposed in the housing 1 and is used to heat the smokeable material 201 in the consumable 200. The heater 4 may be in the form of resistance heating, electromagnetic induction heating, infrared heating, etc.

[0035] The outer side of the heater 4 is sheathed with an insulation tube 5 to prevent heat energy from leaking out. The insulation tube 5 can be made of high temperature resistant insulation material or a vacuum insulation tube. For the infrared heating heater 4, an infrared reflecting surface can also be provided inside the insulation tube 5. The outer side of the insulation tube 5 is further sheathed with a sleeve 6, and the bottom of the sleeve 6 has a mounting position corresponding to the heater 4 and the insulation tube 5, so that the heater 4, the insulation tube 5 and the sleeve 6 can be arranged sequentially from the inside to the outside and keep concentric spacing.

[0036] The top ends of the heater 4, the insulation tube 5 and the sleeve 6 are sequentially inserted on the fixing seat 3 from the inside to the outside and kept in a concentric interval. The fixing seat 3 needs to be able to withstand the high temperature generated by the heater 4, and a high temperature resistant material such as PEEK can be used. A sealing structure is provided between the fixing seat 3 and the heater 4, the insulation tube 5 and the sleeve 6 to prevent heat and smoke from leaking outward along the radial direction of the sleeve 6, thereby forming a second space. As a result, during use, air can enter the internal heating space of the heater 4 from the bottom of the sleeve 6, mix with the inhalable material being heated to form smoke containing aerosol, and be inhaled by the consumer from the mouth end of the consumable.

[0037] The housing 1 of the aerosol generating device 100 is provided with a first space inside, and a power supply 8 and a circuit board 9 are provided in the first space. The power supply 8 is used to provide electric energy to the heater 4, and the circuit board 9 can control the power supply 8 to provide electric energy to the heater 4 as needed. The first space is sealed at the top cover 11 to prevent smoke overflowing from the top of the heater 4 from flowing into the first space during use to contaminate the power supply 8 and the circuit board 9, thereby causing safety hazards such as short circuits.

[0038] like Figure 4-9 As shown, the stopper 7 is detachably arranged at the bottom of the aerosol generating device 100 and extends into the bottom of the heater 4. During use, when the consumable 200 is inserted into the heater 4, the stopper 7 can resist the consumable 200, thereby positioning the consumable 200. During cleaning, the stopper 7 can be removed, and a cleaning tool can be inserted from the bottom of the heater 4 for cleaning.

[0039] The stopper 7 includes a stopper head and a stopper bottom, and the stopper head and the stopper bottom can be integrally formed or composed of two or more parts. The bottom cover 12 is provided with a stopper insertion port 121. When in use, the stopper 7 is inserted into the aerosol generating device 100 through the stopper insertion port 121, at which time the stopper bottom blocks the stopper insertion port 121, and the stopper bottom is flush with the outer surface of the bottom cover 12, thereby ensuring the flatness of the product appearance. When cleaning, the stopper handle 73 on the bottom of the stopper can be moved, and the stopper handle 73 can be rotated about the rotating shaft 74 by about 90°, and the consumer can pull the stopper handle 73 to remove the stopper 7 from the aerosol generating device 100.

[0040] The bottom of the stopper is provided with an air inlet 921, and the external air can smoothly flow into the aerosol generating device 100 along the first gas flow direction (arrow ①). Then, under the guidance of the second air path groove 911 of the lower part of the stopper head 91, the external air gradually converges toward the center along the first gas flow direction (arrow ②), and then passes through the intermediate transition through hole 912 between the lower and upper parts of the stopper head 91, and enters the first air path groove 913. Since the stopper head 91 supports the consumable 200 by extending a number of circumferentially evenly distributed support arms 914 (two in the figure), the external air can quickly diffuse from the gap between the support arms 914 to the surroundings after passing through the intermediate transition through hole 912 and entering the upper part of the stopper head 91, so as to evenly enter the consumable 200 and fully mix with the heated smokeable material, thereby improving the smoke quality and the sensory enjoyment of consumers. In addition, since the main factor determining the suction resistance of the aerosol generating device is only the size and shape of the middle transition through hole 912, it is convenient for designers to adjust the suction resistance to avoid the problem of excessive or insufficient suction resistance of the product, thereby improving consumer quality.

[0041] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
