Referring to fig. 1, an aerosol-generating device 100 according to an embodiment of the present utility model is provided for heating an aerosol-generating substrate 27 (shown in fig. 4) to generate an aerosol for use by a user. Wherein the heating means may be conductive, radiant, ultrasonic or a combination thereof. The aerosol-generating substrate includes, but is not limited to, materials for medical, health, wellness, cosmetic purposes, and the aerosol-generating substrate 27 may be in the form of a gel, paste, solid, or the like. When the aerosol-generating substrate 27 is a solid, it may be a solid in the form of a powder, granulate, powder, granule, bar or tablet, and when the aerosol-generating substrate is a plant-based material, it may be a root, stem, leaf, flower, bud, seed or the like of a plant.

As shown in fig. 1 to 3, the aerosol-generating device 100 includes a housing 40, an atomizer 20, a heating assembly and a suction nozzle 60, the heating assembly is disposed in the housing 40, an atomization passage for accommodating the atomizer 20 is disposed at one end of the housing 40, the atomizer 20 is interchangeably disposed in the atomization passage, the suction nozzle 60 is detachably mounted on the housing 40 and sleeved outside the atomizer 20, and the atomizer 20 can communicate with the external atmosphere through the suction nozzle 60. The atomizer 20 has an aerosol-generating substrate 27 stored therein, and the heating assembly is adapted to provide heat to the atomizing channel to heat the aerosol-generating substrate 27 in the atomizer 20 to generate an aerosol for use by a user.

When the aerosol-generating substrate 27 within the atomizer 20 is exhausted, the atomizer 20 may be pulled out entirely from the power supply assembly and separated from the mouthpiece 60 to replace a new atomizer 20 without the need for manual addition of the aerosol-generating substrate 27 within the atomizer 20, thereby precisely controlling the amount and quality of the aerosol-generating substrate 27 and avoiding the introduction of other impurities during manual addition of aerosol-generating.

Referring to fig. 4 to 6, the atomizer 20 includes a housing compartment 21, a bracket 22, and an air passage skeleton 23. The accommodating chamber 21 has an accommodating cavity 212 with one end open for accommodating the aerosol-generating substrate 27, an axial end of the support 22 is coupled to the open end of the accommodating chamber 21, an axial end of the air passage skeleton 23 is coupled to the other axial end of the support 22, the other axial end of the air passage skeleton 23 is coupled to the suction nozzle 60, the air passage skeleton 23 comprises a first air passage and a second air passage which are arranged at intervals, the first air passage is communicated with the accommodating cavity 212 and the suction nozzle 60, and the second air passage is communicated with the accommodating cavity 212 and the external atmosphere. The two air passages are separately arranged at intervals and are communicated with each other in the atomizer 20 through the accommodating cavity 212.

In this way, the accommodating chamber 21 and the air channel skeleton 23 are connected with each other through the bracket 22, air in the external environment can flow into the accommodating cavity 212 through the second air channel, and aerosol generated by atomizing the aerosol generating substrate 27 in the accommodating cavity 212 can flow into the suction nozzle 60 through the first air channel for the user to take. Because the atomizer 20 integrates the accommodating bin 21 and the air passage framework 23, the updating of the aerosol generating substrate 27 and the replacement of the air passage can be realized simultaneously through the integral replacement of the atomizer 20, the dosage of the aerosol generating substrate 27 is accurately controlled, the cleaning of the air passage is ensured, and the health problems caused by untimely and incomplete cleaning of the air passage are effectively prevented.

The support 22 is a hollow cylindrical structure with two open ends, the accommodating bin 21 is a hollow circular tube structure with one open end, such as a quartz glass tube, a ceramic tube and the like, the open end of the accommodating bin 21 is inserted into one axial end of the support 22, the air passage framework 23 is a hollow rotary body structure, and one axial end of the air passage framework 23 is inserted into the other axial end of the support 22. Thus, the accommodating chamber 21 and the air channel frame 23 are respectively inserted into the two axial ends of the bracket 22 and are connected with each other through the bracket 22, the accommodating chamber 21 is only provided with an opening communicating with the air channel frame 23 at the top, and the bottom wall and the side wall of the accommodating chamber are not provided with communication holes.

In this way, the accommodating bin clamping portion 214 is clamped with the first bracket clamping portion 221, and the second bracket clamping portion 223 is clamped with the framework clamping portion, so that the accommodating bin 21, the bracket 22 and the air passage framework 23 form a non-detachable whole. The term "non-removable" means that the atomizer 20 cannot be removed without being destroyed, and is mainly replaced by a forced whole in order to prevent the atomizer 20 from being secondarily charged with the aerosol-generating substrate 27.

Specifically, in one embodiment, an edge of an axial end of the bracket 22 is turned inward to form an annular first bracket clamping portion 221, and an edge of an open end of the accommodating bin 21 is turned outward to form an annular accommodating bin clamping portion 214, and a lower surface of the accommodating bin clamping portion 214 is used for abutting against an upper surface of the first bracket clamping portion 221. When a user tries to pull the holder 22 and the receiving container 21 to separate them, the first holder clamping portion 221 may function to prevent the receiving container clamping portion 214 from moving, thereby preventing the holder 22 and the receiving container 21 from being separated from each other.

Part of the inner surface of the side wall of the other axial end of the bracket 22 is outwardly convex, thereby forming a second bracket catching portion 223 in the form of an annular projection. The outer surface of the part of the side wall of the airway skeleton 23 extending into the bracket 22 is recessed inwards to form a skeleton clamping part in the shape of an annular groove, and the shape of the skeleton clamping part is matched with that of the second bracket clamping part 223 so as to be embedded in the second bracket clamping part 223. When a user tries to pull the bracket 22 and the airway skeleton 23 to separate them, the second bracket locking portion 223 may function to prevent the skeleton locking portion from moving, thereby preventing the bracket 22 and the airway skeleton 23 from being separated from each other.

It will be appreciated that the manner of coupling the bracket 22 to the housing compartment 21 and the air channel skeleton 23 is not limited thereto, and in other embodiments, the bracket may be assembled in a manner that is not easily detachable, such as by a turnbuckle connection, ultrasonic welding, etc., so as to avoid the atomizer 20 from being detached by a user. In addition, the bracket 22 and the accommodating bin 21, and the bracket 22 and the air passage framework 23 can be integrally formed by adopting a printing and other forming modes.

When the user inhales, air from the external environment can flow into the bottom of the receiving cavity 212 through the peripheral air channel 212a, and then, aerosol generated by atomizing the aerosol-generating substrate 27 is carried into the mouthpiece 60 through the central air channel 234a and the air discharge channel 232a in sequence. At the same time, the airflow flowing into the first edge air passage 212a from the edge air inlet 232d may partially enter the outlet end of the central air passage 234a through the central tube 234 auxiliary air inlet 232c, mix with the aerosol in the central air passage 234a to reduce the concentration of the aerosol, hypoxia atomize the aerosol-generating substrate 27, and regulate the temperature of the airflow flowing into the mouthpiece 60.

Further in the third and fourth embodiments, as shown in fig. 9 and 11, the atomizer 20 further includes a flow blocking baffle disposed on the inner wall of the exhaust channel 232a or the central air channel 234a to block a portion of the first air channel for preventing the aerosol-generating substrate 27 from splashing out of the mouthpiece 60 when heated.

In particular, in one embodiment, the choke flap includes a choke top wall 252 and a choke side wall 254 extending in the same direction from the choke top wall 252, wherein an end of the choke side wall 254 away from the choke top wall 252 is inserted into the outlet end of the central air channel 234 a. The flow-blocking top wall 252 shields the outlet end of the central air passage 234a, and the flow-blocking side wall 254 opens a lateral air outlet communicating the central air passage 234a with the air discharge passage 232 a.

As such, larger diameter aerosol particles in the central air passage 234a impinge on the inside of the outlet end of the central air passage 234a or on the flow-blocking baffle without entering the mouth of the user affecting the mouth feel of the suction. Moreover, the flow blocking flap may mask the outlet end of the central air passage 234a to prevent a user from adding aerosol-generating substrate 27 through the central air passage 234 a.

In some embodiments, the airway inner wall of the first airway is at least partially configured as a damping structure for impeding the aerosol-generating substrate 27 from sliding down to the receiving cavity 212, in particular, the damping structure is at least one of a step, an arc, a rough surface, an annular groove, or an annular barrier formed on the airway inner wall of the first airway. As such, if a user adds aerosol-generating substrate 27 to the first airway, the damping structure will block the aerosol-generating substrate 27 from sliding down to the receiving cavity 212.

Referring to fig. 5 and 6 again, in some embodiments, the atomizer 20 further includes an annular sealing member 24, and the sealing member 24 is clamped between the holding chamber clamping portion 214 and the end surface of the air channel frame 23, so as to close the gap between the holding chamber 21 and the air channel frame 23 and prevent the air flow in the first edge air channel 212a and the second edge air channel 212a from leaking from the gap between the holding chamber 21 and the air channel frame 23. It will be appreciated that in other embodiments, the seal may be formed in an end-face interference contact, radial interference contact, without the need for the seal 24.

In some embodiments, the atomizer 20 further comprises a damping member 26, and the damping member 26 is sleeved outside the air passage skeleton 23. Specifically, in one embodiment, the outer surface of the sidewall of the air channel skeleton 23 forms an annular receiving groove extending in the circumferential direction, and the damping member 26 is annular to be embedded in the receiving groove. When the atomizer 20 is inserted into the power supply assembly, a certain damping is formed between the damping member 26 and the power supply assembly, so that the atomizer 20 is prevented from sliding off the power supply assembly. It will be appreciated that the manner of improving the connection stability of the atomizer 20 to the power supply assembly is not limited thereto, and may be by magnetic connection, snap connection, twist connection.

The atomizer 20 further comprises an aerosol-generating substrate 27, the aerosol-generating substrate 27 being received in the receiving cavity 212 for generating an aerosol upon heating. It should be noted that the aerosol-generating substrate 27 is pre-stored in the substrate receiving cavity during assembly of the atomizer 20, and the user only needs to add the aerosol-generating substrate 27 by replacing the atomizer 20.

In some embodiments, the atomizer 20 further comprises a heat generating body (not shown) housed within the housing cavity 212, the power assembly having a component therein operable to generate a magnetic field, the heat generating body being operable to be inductively heated in the magnetic field to atomize the aerosol-generating substrate 27. In other embodiments, the aerosol-generating substrate 27 may be heated by infrared, microwave, plasma, or the like means without the provision of a heating element.

The above-mentioned atomizer 20 and aerosol-generating device 100, the atomizer 20 integrated with the housing compartment 21 and the air channel skeleton 23 is detachably mounted on the power supply assembly, and the aerosol-generating substrate 27 is updated by integrally replacing the atomizer 20, without manually adding the aerosol-generating substrate 27 by a user, thereby precisely controlling the amount of the aerosol-generating substrate 27. Moreover, the part of the air passage can be cleaned by replacing the atomizer 20, so that the health problem caused by pollution caused by deposited impurities in the air passage is avoided. In addition, since the suction nozzle 60 of the aerosol-generating device 100 is reusable, replacement costs of the atomizer 20 are reduced.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the claims. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
