Referring to fig. 1, an embodiment of the present utility model provides an aerosol-generating device 100 for heating an aerosol-generating substrate 416 to generate an aerosol for use by a user. Wherein the heating means may be heat conduction, infrared radiation, ultrasound, microwaves, plasma 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 416 may be in the form of a gel, paste, solid, or the like. When the aerosol-generating substrate 416 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, etc. of a plant.

As shown in fig. 1 and 2, the aerosol-generating device 100 includes a housing 20, an atomizer 40, and a heating assembly 60. The heating assembly 60 is disposed in the housing 20, one end of the housing 20 is provided with an atomization channel for accommodating the atomizer 40, the atomizer 40 is detachably disposed in the atomization channel, the atomizer 40 includes an atomized capsule 41 and a nozzle assembly 43, the atomized capsule 41 stores an aerosol-generating substrate 416 (as shown in fig. 4), and the nozzle assembly 43 is detachably coupled to the atomized capsule 41. The heating assembly 60 may heat the aerosolized aerosol-generating substrate 416 in the aerosolized capsule 41 to generate an aerosol, which may flow out through the mouthpiece assembly 43 for access by a user.

When the aerosol-generating substrate 416 within the aerosolized capsule 41 is spent, the atomizer 40 may be pulled entirely out of the housing 20 and the aerosolized capsule 41 separated from the mouthpiece assembly 43 to replace a new aerosolized capsule 41 without the need for manual addition of the aerosol-generating substrate 416 within the aerosolized capsule 41, thereby precisely controlling the amount and quality of the aerosol-generating substrate 416 and avoiding the introduction of other impurities during manual addition of aerosol-generating.

Referring to fig. 3 to 5, the housing 20 has a cylindrical structure, an atomizing channel for accommodating the atomized capsule 41 is formed at one axial end of the housing 20, and the heating assembly 60 is accommodated in the other axial end of the housing 20. It will be appreciated that the shape of the housing 20 is not limited, and the internal configuration of the housing 20 and the heating assembly 60 is not a major aspect of the present utility model and will not be described herein.

The aerosolized capsule 41 includes a tube 412, a sealing membrane 414, and an aerosol-generating substrate 416. The tube 412 has a hollow circular tube structure, such as a quartz glass tube, a ceramic tube, etc., and the tube 412 has a housing cavity 4121 with one end opened. The sealing film 414 is encapsulated at the opening end of the tube 412 to close the accommodating cavity 4121. Since the tube 412 is sealed by the sealing membrane 414, air is isolated to prevent the aerosol-generating substrate 416 from oxidative deterioration, and at the same time, to prevent the user from introducing impurities by self-feeding the aerosol-generating substrate 416 into the receiving cavity 4121, thereby ensuring the quality of the aerosol-generating substrate 416.

The suction nozzle assembly 43 includes a suction nozzle 432 and a puncture gas tube 434. The suction nozzle 432 is a hollow revolving body structure, and has a first air passage and a second air passage which are communicated with the atmosphere and are arranged at intervals. One end of the puncture gas pipe 434 is coupled to one end of the suction nozzle 432 and communicates with the first gas passage, and the other end of the puncture gas pipe 434 extends out of the suction nozzle 432. When the suction nozzle 432 and the atomized capsule 41 are mutually matched, the suction nozzle 432 is covered on the opening end of the tube body 412, and one end of the puncture gas tube 434 can puncture the sealing membrane 414 to extend into the accommodating cavity 4121.

In this way, the piercing gas pipe 434 communicates the housing chamber 4121 of the aerosol capsule 41 with the first gas passage of the mouthpiece 432, and the space between the side wall of the piercing gas pipe 434 and the chamber wall of the housing chamber 4121 communicates with the second gas passage. In some embodiments, ambient air may flow into the housing cavity 4121 through the first airway, the piercing airway 434, and then aerosol generated by aerosolization of the aerosol-generating substrate 416 may flow into the second airway through the gap between the sidewall of the piercing airway 434 and the cavity wall of the housing cavity 4121. In other embodiments, ambient air may flow into the housing chamber 4121 through the second airway, the void between the sidewall of the piercing airway 434 and the chamber wall of the housing chamber 4121 in sequence, and then flow into the first airway carrying aerosol generated by the aerosolization of the aerosol-generating substrate 416.

Before the use of the nebulizer 40, the piercing air tube 434 of the suction nozzle assembly 43 pierces the sealing film 414 of the nebulized capsule 41, and then the nebulizer 40 is inserted into the nebulization channel of the aerosol-generating device 100 as a whole, so that inhalation can be performed after starting. After the aerosol-generating substrate 416 is exhausted, the atomizer 40 may be pulled out entirely from the aerosol-generating device 100, and the nozzle assembly 43 may be pulled out from the atomizer 40 to replace a new aerosolized capsule 41, so that the user does not need to add the aerosol-generating substrate 416 by himself, thereby precisely controlling the amount and quality of the aerosol-generating substrate 416, avoiding introducing other impurities during the manual addition of the aerosol-generating substrate 416, and ensuring the quality of the aerosol-generating substrate 416.

Specifically, the outer sidewall of the puncture trachea 434 is convexly provided with a plurality of ribs 434a, all ribs 434a are arranged at intervals along the circumferential direction of the puncture trachea 434, and each rib 434a extends along the axial direction of the puncture trachea 434. Thus, when the puncture tube 434 extends into the accommodating chamber 4121, a gap is defined between the adjacent two ribs 434a and the wall of the accommodating chamber 4121 to form a second air passage. It will be appreciated that the number and shape of ribs 434a are not limited thereto and may be configured as desired to meet various requirements. It should be noted that, in order to avoid leakage of the aerosol after piercing, the sealing film 414 may be made of an elastic material, such as a silicone, PET, PP, or an aluminum plastic film. In addition, in order to ensure that the puncture gas tube 434 is inserted into the tube body 412 to a proper depth, a limiting portion may be further disposed on the puncture gas tube 434, for example, an abutting portion (not shown in the drawings) may be formed between an outer wall of the puncture gas tube 434 and an end face of an opening end of the tube body, which is not described in detail herein.

In some embodiments, the aerosolized capsule 41 further comprises a heat-generating body (not shown) housed within the housing cavity 4121, the housing 20 having a component therein that generates a magnetic field, the heat-generating body being operable to be inductively heated in the magnetic field to aerosolize the aerosol-generating substrate 416. It will be appreciated that in other embodiments, the aerosol-generating substrate 416 may be heated by infrared, microwave, plasma, etc. means without a heating element being provided in the aerosolized capsule 41.

In the first embodiment of the present utility model, the suction nozzle 432 includes a suction portion 4321, a first connection portion 4323, and a second connection portion 4325. The first connection portion 4323 and the second connection portion 4325 are both connected to the same axial end of the suction portion 4321, and the second connection portion 4325 is disposed at intervals on the outer periphery of the second connection portion 4325. An exhaust passage 4312a communicating with the outside atmosphere is formed in the suction portion 4321, a central air passage 4323a is formed in the first connection portion 4323, an edge air passage 4325a provided at an interval on the outer periphery of the central air passage 4323a is formed between the first connection portion 4323 and the second connection portion 4325, and one end of the edge air passage 4325a communicates with the exhaust passage 4312 a. The suction nozzle 432 is further provided with a lateral air passage (not shown), an air inlet end of the lateral air passage is formed in a side wall of the suction portion 4321, and an air outlet end of the lateral air passage is communicated with the central air passage 4323a. One end of the puncture tube 434 is inserted into one end of the first connection part 4323, which is remote from the suction part 4321, to communicate with the central air passage 4323a.

Thus, the exhaust passage 4312a and the edge air passage 4325a are communicated with each other to form a first air passage together, and the exhaust passage 4312a is disposed at one end of the suction nozzle 432 communicated with the external atmosphere, and the center air passage 4323a and the lateral air passage form a second air passage together. When the suction nozzle 432 is coupled to the atomized capsule 41, the end of the second connecting portion 4325 away from the suction portion 4321 is sleeved outside the open end of the tube body 412, the end of the edge air channel 4325a away from the exhaust channel 4312a is communicated with the gap between the puncture air tube 434 and the cavity wall of the accommodating cavity 4121, and the end of the puncture air tube 434 away from the first connecting portion 4323 extends into the accommodating cavity 4121.

When the user sucks the suction nozzle 432, air in the external environment flows into the accommodating cavity 4121 through the lateral air passage, the central air passage 4323a and the puncture air tube 434 in sequence, and then aerosol generated by atomizing the aerosol generating substrate 416 is carried out of the suction nozzle 432 through the edge air passage 4325a and the exhaust air passage 4312a in sequence.

In the second embodiment of the present utility model, the suction nozzle 432 includes a suction portion 4321, a first connection portion 4323, and a second connection portion 4325, as in the first embodiment. The first connection portion 4323 and the second connection portion 4325 are both connected to the same axial end of the suction portion 4321, and the second connection portion 4325 is disposed at intervals on the outer periphery of the second connection portion 4325. An exhaust passage 4312a communicating with the outside atmosphere is formed in the suction portion 4321, a central air passage 4323a is formed in the first connection portion 4323, an edge air passage 4325a provided at an interval on the outer periphery of the central air passage 4323a is formed between the first connection portion 4323 and the second connection portion 4325, and one end of the edge air passage 4325a communicates with the exhaust passage 4312 a. The suction nozzle 432 is also provided with a lateral air passage, the air inlet end of the lateral air passage is arranged on the side wall of the suction part 4321, and the air outlet end of the lateral air passage is communicated with the central air passage 4323a. One end of the puncture tube 434 is inserted into one end of the first connection part 4323, which is remote from the suction part 4321, to communicate with the central air passage 4323a.

Thus, the exhaust passage 4312a and the edge air passage 4325a are communicated with each other to form a first air passage together, and the exhaust passage 4312a is disposed at one end of the suction nozzle 432 communicated with the atmosphere, and the center air passage 4323a and the lateral air passage form a second air passage together. When the suction nozzle 432 is coupled to the atomized capsule 41, the end of the second connecting portion 4325 away from the suction portion 4321 is sleeved outside the open end of the tube body 412, the end of the edge air channel 4325a away from the exhaust channel 4312a is communicated with the gap between the puncture air tube 434 and the cavity wall of the accommodating cavity 4121, and the end of the puncture air tube 434 away from the first connecting portion 4323 extends into the accommodating cavity 4121.

The difference from the third embodiment is that the side wall of the second connection part 4325 of the suction nozzle 432 is opened with an auxiliary air flow hole, which communicates with the rim air channel 4325 a. When the user sucks the suction nozzle 432, air in the external environment flows into the accommodating cavity 4121 through the lateral air passage, the central air passage 4323a and the puncture air tube 434 in sequence, and then aerosol generated by atomizing the aerosol generating substrate 416 is carried out of the suction nozzle 432 through the edge air passage 4325a and the exhaust air passage 4312a in sequence. At the same time, air from the external environment may also flow from the auxiliary airflow aperture into the rim channel 4325a and then mix with the aerosol in the rim channel 4325a to reduce the concentration of the aerosol, to hypoxia atomize the aerosol-generating substrate 416, and to regulate the temperature of the airflow exiting the mouthpiece 432.

Further in the first embodiment and the second embodiment, the mouthpiece assembly 43 further includes a blocking piece 436, and the blocking piece 436 is disposed on an inner wall of the exhaust channel 4312a or the central air channel 4323a to block part of the first air channel, so as to prevent the aerosol-generating substrate 416 from splashing out of the mouthpiece 432 when heated.

In particular, in one embodiment, the choke flap 436 includes a choke top wall and a choke side wall extending in the same direction from the choke top wall, and an end of the choke side wall away from the choke top wall is inserted into the outlet end of the central air channel 4323a. The top wall of the choke shields the outlet end of the central air passage 4323a, and the side wall of the choke is provided with a lateral air outlet which is communicated with the central air passage 4323a and the exhaust passage 4312 a.

In this way, larger diameter aerosol particles in the central air passage 4323a impinge on the inside of the outlet end of the central air passage 4323a or on the flow-blocking baffle without entering the mouth of the user to affect the mouth feel of the suction. Moreover, the blocker 436 may mask the outlet end of the central air passage 4323a to prevent a user from adding aerosol-generating substrate 416 through the central air passage 4323a.

In the third embodiment of the present utility model, the suction nozzle 432 includes a suction portion 4321, a first connection portion 4323, and a second connection portion 4325. The first connection portion 4323 and the second connection portion 4325 are both connected to the same axial end of the suction portion 4321, and the second connection portion 4325 is disposed at intervals on the outer periphery of the second connection portion 4325. The suction portion 4321 forms an exhaust passage 4312a communicating with the outside atmosphere, a central air passage 4323a communicating with the exhaust passage 4312a and coaxially arranged with the exhaust passage 4312a is formed in the first connection portion 4323, an edge air passage 4325a is formed between the first connection portion 4323 and the second connection portion 4325 at intervals arranged at the outer periphery of the central air passage 4323a, and an air inlet end of the edge air passage 4325a is opened at a side wall of the second connection portion 4325 of the suction nozzle 432. One end of the puncture tube 434 is inserted into one end of the first connection part 4323, which is remote from the suction part 4321, to communicate with the central air passage 4323a.

Thus, the exhaust passage 4312a and the central air passage 4323a communicate with each other to form a first air passage together, and the peripheral air passage 4325a forms a second air passage. When the suction nozzle 432 is coupled to the atomized capsule 41, an end of the second connecting portion 4325, which is far away from the suction portion 4321, is sleeved outside the open end of the tube body 412, the second air passage is communicated with a gap between the puncture air tube 434 and the cavity wall of the accommodating cavity 4121, and an end of the puncture air tube 434, which is far away from the first connecting portion 4323, extends into the accommodating cavity 4121.

When the user sucks the suction nozzle 432, air in the external environment enters the suction nozzle 432 from the edge air passage 4325a and reaches the bottom of the accommodating cavity 4121, and then aerosol generated by atomizing the aerosol generating substrate 416 is carried out of the suction nozzle 432 through the puncture air tube 434, the central air passage 4323a and the exhaust channel 4312a in sequence.

In the fourth embodiment of the present utility model, the suction nozzle 432 includes a suction portion 4321, a first connection portion 4323, and a second connection portion 4325, as in the suction nozzle 432 of the third embodiment. The first connection portion 4323 and the second connection portion 4325 are both connected to the same axial end of the suction portion 4321, and the second connection portion 4325 is disposed at intervals on the outer periphery of the second connection portion 4325. The suction portion 4321 forms an exhaust passage 4312a communicating with the outside atmosphere, a central air passage 4323a communicating with the exhaust passage 4312a and coaxially arranged with the exhaust passage 4312a is formed in the first connection portion 4323, an edge air passage 4325a is formed between the first connection portion 4323 and the second connection portion 4325 at intervals arranged at the outer periphery of the central air passage 4323a, and an air inlet end of the edge air passage 4325a is opened at a side wall of the second connection portion 4325 of the suction nozzle 432. One end of the puncture tube 434 is inserted into one end of the first connection part 4323, which is remote from the suction part 4321, to communicate with the central air passage 4323a.

Thus, the exhaust passage 4312a and the central air passage 4323a communicate with each other to form a first air passage together, and the peripheral air passage 4325a forms a second air passage. When the suction nozzle 432 is coupled to the atomized capsule 41, an end of the second connecting portion 4325, which is far away from the suction portion 4321, is sleeved outside the open end of the tube body 412, the second air passage is communicated with a gap between the puncture air tube 434 and the cavity wall of the accommodating cavity 4121, and an end of the puncture air tube 434, which is far away from the first connecting portion 4323, extends into the accommodating cavity 4121.

The difference from the first embodiment is that the air passage wall of the central air passage 4323a (i.e., the side wall of the second connecting portion 4325) is provided with a vent hole communicating with the peripheral air passage 4325 a. Thus, when the user sucks the suction nozzle 432, air in the external environment enters the suction nozzle 432 from the edge air channel 4325a and reaches the bottom of the accommodating cavity 4121, and then the aerosol generated by atomizing the aerosol-generating substrate 416 flows out of the suction nozzle 432 through the puncture air tube 434, the central air channel 4323a and the exhaust channel 4312 a. At the same time, a portion of the airflow flowing into the peripheral airway 4325a may flow partially through the vent holes into the central airway 4323a, mix with the aerosol in the central airway 4323a to a lesser aerosol concentration, low-oxygen aerosolize the aerosol-generating substrate 416, and regulate the temperature of the airflow exiting the mouthpiece 432.

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 416 from sliding down to the receiving cavity 4121, in particular, the damping structure is at least one of a step, an arcuate surface, a roughened surface, an annular groove, and an annular barrier formed on the airway inner wall of the first airway. As such, if the user adds aerosol-generating substrate 416 to the first airway, the damping structure will block the aerosol-generating substrate 416 from sliding down into the receiving cavity 4121.

In the above-mentioned aerosol-generating device 100 and aerosol-generating device 41, the aerosol-generating substrate 416 is detachably connected to the mouthpiece assembly 43 in the aerosol-generating device 41, and the aerosol-generating substrate 416 can be updated by replacing the aerosol-generating device 41 without manually adding the aerosol-generating substrate 416 by a user, so that the amount of the aerosol-generating substrate 416 is precisely controlled, and the quality of the aerosol-generating substrate 416 is ensured.

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.
