[0035] Figure 1 This is a schematic diagram of the structure of an aerosol generating device provided in an embodiment of the present application. Figure 1 As shown, the aerosol generating device includes a power supply component 100 and an atomizer 200. The power supply component 100 is used to supply power to the atomizer 200. As an example, the aerosol generating device may further include a housing 300, in which both the power supply component 100 and the atomizer 200 are located.

[0036] Figure 2 This is a schematic diagram of the internal structure of an atomizer provided in an embodiment of the present application. Figure 2 As shown, the nebulizer 200 includes a liquid storage component 210 and an atomizing component 220. The liquid storage component 210 is used to store the aerosol matrix. The atomizing component 220 is located in the liquid storage component 210 and is used to heat the aerosol matrix. The atomizing component 220 is formed with an atomizing channel 220a.

[0037] The liquid storage assembly 210 may include a liquid storage housing 211, wherein the interior of the liquid storage housing 211 forms a liquid storage for containing the aerosol matrix. In some examples, the liquid storage assembly 210 may further include a liquid storage member, such as a liquid storage cotton, which is adsorbed / impregnated with the aerosol matrix.

[0038] Atomizer assembly 220 is located within liquid reservoir housing 211. Atomizer assembly 220 also includes a bracket 221, a liquid guide 222, and a heater 223. Bracket 221 forms atomization channel 220a, and liquid guide 222 and heater 223 are located within bracket 221. The material and structure of heater 223 are not limited, as long as they can generate heat. For example, heater 223 may include at least one of a heating mesh, a heating film, a heating wire, or a heating plate.

[0039] The bracket 221 provides space within the liquid reservoir housing 211 to accommodate the liquid guide 222 and the heater 223. The bracket 221 may be tubular, and its walls may include holes, slits, or other structures to allow aerosol substrate in the liquid reservoir housing 211 to enter the atomization channel 220a and be absorbed by the liquid guide 222. The heater 223 is used to heat the aerosol substrate in the liquid guide 222, vaporizing it.

[0040] The liquid tank housing 211 has a through hole 211 a at one end facing the outlet of the atomization channel 220 a , and the aerosol matrix heated and vaporized by the heating element 223 can be discharged outwardly through the through hole 211 a .

[0041] The heating element 223 may be connected to an electrode, which is exposed from the liquid reservoir housing 211. The power supply assembly 100 may have a power supply terminal, which may be in electrical contact with the electrode exposed from the liquid reservoir housing 211, thereby supplying power to the atomizer 200.

[0042] In some examples, the power supply assembly 100 is detachably connected to the atomizer 200. Since the power supply assembly 100 is detachably connected to the atomizer 200, the atomizer 200 can be easily replaced.

[0043] In other examples, the power supply assembly 100 and the atomizer 200 may be fixedly connected. For example, the housing portion of the power supply assembly 100 and the liquid reservoir housing 211 of the atomizer 200 are an integrated structure.

[0044] In the related art, the through hole 211a of the liquid tank housing 211 is usually used to connect a nozzle, such as a filter nozzle with a filtering function. However, due to the differences in structure and size of different nozzles, the atomizer 200 can adapt to a limited number of nozzles.

[0045] The atomizer 200 provided in the embodiment of the present application may further include a nozzle connector 230, which is connected to the liquid storage assembly 210 of the atomizer 200. A nozzle 240 may be connected to the nozzle connector 230 for use.

[0046] Figure 3 This is a schematic diagram of the structure of a nozzle connector provided in an embodiment of the present application. Figure 3 As shown, the nozzle connector 230 includes a tubular body 231 and a sealing member 232. The tubular body 231 has a first end and a second end. The first end of the tubular body 231 is used to connect to the liquid storage assembly 210 of the atomizer, and the sealing member 232 is sleeved outside the first end of the tubular body 231. The sealing member 232 is used to seal with the liquid storage assembly 210.

[0047] By sleeved with the sealing member 232 on the first end of the tubular body 231 , when the first end of the tubular body 231 is connected to the liquid storage assembly 210 of the atomizer 200 , the sealing member 232 can seal the gap between the tubular body 231 and the liquid storage assembly 210 .

[0048] In some cases, when the atomizer needs to be used with the suction nozzle 240, if the suction nozzle 240 is not matched and cannot be directly connected to the liquid storage component 210, the first end of the tubular body 231 can be connected to the liquid storage component 210, and the suction nozzle 240 can be connected to the second end of the tubular body 231 for use, so that the atomizer 200 can be adapted to more types of suction nozzles 240.

[0049] In other cases, if the atomizer does not need to be used with the mouthpiece 240, the first end of the tubular body 231 is connected to the liquid storage assembly 210, and the second end of the tubular body 231 can also be directly put into the mouth of the user for use.

[0050] like Figure 2 As shown, one side of the liquid tank housing 211 is concave to form a slot 211b. The through hole 211a can be located at the bottom of the slot 211b. The first end of the tubular body 231 is inserted into the slot 211b, and the sealing member 232 abuts against the inner side wall of the slot 211b.

[0051] The seal 232 and the inner side wall of the slot 211b squeeze each other, thereby sealing the gap between the tubular body 231 and the inner side wall of the slot 211b, preventing the aerosol formed in the atomization channel 220a from leaking from the gap. The connection through the slot 211b facilitates the disassembly and assembly between the nozzle connector 230 and the liquid tank housing 211. When the nozzle 240 is compatible with the slot 211b, the nozzle connector 230 can be removed and the nozzle 240 can be directly inserted into the slot 211b for use; when the nozzle 240 is not compatible with the slot 211b, the nozzle connector 230 can be plugged into the slot 211b to connect the nozzle 240 to the nozzle connector 230.

[0052] Exemplarily, the sealing member 232 may be an annular sealing ring, such as an O-ring.

[0053] Figure 4 This is a schematic diagram of the structure of a tubular body provided in an embodiment of the present application. Figure 4As shown, the outer side wall of the tubular body 231 has an annular groove 231 a , and the sealing member 232 is located in the annular groove 231 a .

[0054] Arranging the seal 232 through the annular groove 231a can make the seal 232 more secure. In addition, the annular groove 231a can also increase the contact area between the seal 232 and the tubular body 231. Under the extrusion effect, the sealing area between the seal 232 and the tubular body 231 is larger, which can improve the sealing performance.

[0055] As an example, there may be a plurality of annular grooves 231 a , and the plurality of annular grooves 231 a are arranged at intervals along the axial direction of the tubular body 231 .

[0056] By providing a plurality of annular grooves 231 a and disposing a sealing member 232 in each annular groove 231 a , multiple seals can be formed, thereby further improving the sealing performance.

[0057] For example, the outer side wall of the tubular body 231 may have two annular grooves 231 a.

[0058] like Figure 4 As shown, the outer side wall of the tubular body 231 has an annular stop 231 b , and the annular stop 231 b is located on a side of the sealing member 232 close to the second end of the tubular body 231 .

[0059] When the tubular body 231 is inserted into the slot 211b of the liquid tank shell 211, the annular stop 231b can cooperate with the opening of the slot 211b, and the annular stop 231b is in contact with the surface of the liquid tank shell 211, which not only makes the tubular body 231 more stably installed, but also further improves the air tightness between the tubular body 231 and the slot 211b.

[0060] Figure 5 This is a schematic diagram of the internal structure of a tubular body provided in an embodiment of the present application. Figure 5 As shown, the inner hole of the tubular body 231 includes a first section 2311 and a second section 2312 with different apertures. The aperture of the first section 2311 is smaller than that of the second section 2312, and the first section 2311 is close to the first end of the tubular body 231.

[0061] Because the apertures of the first section 2311 and the second section 2312 are different, and the aperture of the first section 2311 near the first end of the tubular body 231 is smaller, a step structure is formed within the tubular body 231. This step structure can be used to position the suction nozzle 240. When the suction nozzle 240 is inserted into the second section of the inner hole of the tubular body 231, the suction nozzle 240 can be inserted until it abuts against the step structure.

[0062] In some examples, the ratio of the length of the second section 2312 of the inner bore of the tubular body 231 to the total length of the tubular body 231 is no less than 50%.

[0063] The second section 2312 of the inner bore of the tubular body 231 is used to accommodate the suction nozzle 240. The shorter the length of the second section 2312, the more likely the suction nozzle 240 will become loose. The length of the second section 2312 of the inner bore of the tubular body 231 is set to be no less than 50% of the total length of the tubular body 231, ensuring that the suction nozzle 240 is sufficiently long to fit within the tubular body 231, thereby reducing the risk of the suction nozzle 240 becoming loose.

[0064] Figure 6 This is a schematic diagram of the internal structure of another tubular body provided in an embodiment of the present application. Figure 6 As shown, in some examples, the aperture of the second section 2312 of the inner hole of the tubular body 231 gradually increases from an end close to the first end of the tubular body 231 to an end close to the second end of the tubular body 231 .

[0065] That is to say, the second section 2312 of the inner hole of the tubular body 231 is a tapered hole, and the end with the smaller inner diameter is close to the first section 2311 of the inner hole of the tubular body 231. Different nozzles 240 may have different diameters. When inserting the nozzle 240 into the tubular body 231, the insertion depth can be determined according to the diameter of the nozzle 240. The smaller the diameter of the nozzle 240, the deeper it can be inserted, so that the outer wall of the nozzle 240 is in close contact with the inner wall of the tubular body 231, achieving a sealing effect, thereby improving airtightness and avoiding air leakage. It can be seen that setting the second section 2312 of the inner hole of the tubular body 231 as a tapered hole can enable the nozzle connector 230 to accommodate more nozzles 240.

Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
