[0043] Figure 1 It is a schematic structural diagram of a suction nozzle provided by an embodiment of the present application. As Figure 1As shown, the nozzle includes a housing 20 and a heating module 12. The housing 20 has an air flow channel 21a and a nozzle opening 20a communicating with the air flow channel 21a. The heating module 12 is disposed in the housing 20 and is configured to heat the air flow channel 21a.

[0044] In an embodiment of the present application, by forming an air flow channel 21a inside the housing 20, one end of the air flow channel 21a communicates with the nozzle opening 20a. When the aerosol generating device is in use, the atomized aerosol matrix moves towards the nozzle opening 20a via the air flow channel 21a. Since the nozzle further includes a heating module 12, the heating module 12 can heat the air flow channel 21a, so that the atomized aerosol matrix can be maintained in a gaseous state inside the air flow channel 21a, avoiding the cold liquefaction of the atomized aerosol matrix in the air flow channel 21a.

[0045] As Figure 1 shown, the housing 20 may include an outer housing 22 and a first tube 21. Among them, the outer housing 22 has a nozzle opening 20a. The outer housing 22 is used to form the external shape of the nozzle. The first tube 21 is located inside the outer housing 22, and the first tube 21 forms the air flow channel 21a. One end of the first tube 21 is connected to the outer housing 22 at the nozzle opening 20a.

[0046] In some examples, the outer housing 22 and the first tube 21 may be detachably connected to facilitate production, assembly, and replacement of components.

[0047] In other examples, the outer housing 22 and the first tube 21 may also be fixedly connected. For example, the outer housing 22 and the first tube 21 are ultrasonically welded; alternatively, the outer housing 22 and the first tube 21 are an integrally formed structure.

[0048] As Figure 1 shown, the heating module 12 is located outside the first tube 21, and the heat generated during the operation of the heating module 12 is conducted through the first tube 21 to the inside of the first tube 21 to maintain the temperature inside the air flow channel 21a higher than the ambient temperature, so as to avoid or reduce the liquefaction of the aerosol matrix.

[0049] Exemplarily, the heating temperature of the heating module 12 may be 35°C to 50°C.

[0050] As Figure 1 shown, the heating module 12 is arranged around the air flow channel 21a.

[0051] Arranging the heating module 12 around the air flow channel 21a can make the temperature inside the air flow channel 21a more uniform, avoiding local liquefaction of the aerosol matrix due to a lower temperature in a local area.

[0052] As Figure 1As shown, the heating module 12 includes a first heating element 121 and a first electrode 122 that are electrically connected. The first electrode 122 extends along a side of the first heating element 121 away from the nozzle opening 20a, and at least a part of the first electrode 122 is located on the surface of the first tube body 21.

[0053] The first electrode 122 is used to supply power to the first heating element 121 so that the first heating element 121 generates heat. Arranging at least a part of the first electrode 122 on the surface of the first tube body 21 can facilitate power supply to the heating module 12. For example, when the nozzle is applied to an aerosol generating device, power can be supplied to the heating module 12 by contacting a part of the first electrode 122 located on the surface of the first tube body 21 with other power supply structures.

[0054] The material and structure of the first heating element 121 are not limited as long as it can play a role in generating heat. Exemplarily, the first heating element 121 may include at least one of a heating mesh, a heating film, a heating wire, and a heating sheet.

[0055] As an example, in the embodiments of the present application, the first heating element 121 includes a heating coil. When the first heating element 121 is a heating coil, the heating coil can be sleeved outside the first tube body 21.

[0056] When the first heating element 121 includes at least one of a heating sheet, a heating film, a heating mesh, and a heating wire, for example, the first heating element 121 may include a plurality of heating sheets, and the plurality of heating sheets are arranged around the air flow channel 21a.

[0057] As Figure 1 shown, a part of the first electrode 122 may be exposed on the inner wall of the first tube body 21. In this example, the first heating element 121 is located outside the first tube body 21, the first electrode 122 is embedded in the tube wall of the first tube body 21, one end is exposed on the outer wall of the first tube body 21 and is connected to the first heating element 121, and the other end is exposed on the inner wall of the first tube body 21.

[0058] In some other examples, the heating module 12 may also be located inside the first tube body 21. For example, the first heating element 121 of the heating module 12 is located on the inner side wall of the first tube body 21, so as to directly heat the inside of the air flow channel 21a.

[0059] Optionally, the first tube body 21 may have a receiving groove (not shown in the figures), and at least part of the heating module 12 is located in the receiving groove. The receiving groove may be located on the outer wall of the first tube body 21 or on the inner wall of the first tube body 21. The position of the receiving groove may be set according to the position where the heating module 12 is arranged. For example, if the heating module 12 is arranged outside the first tube body 21, a receiving groove may be provided on the outer wall of the first tube body 21; if the heating module 12 is arranged inside the first tube body 21, a receiving groove may be provided on the inner wall of the first tube body 21.

[0060] In still other examples, the heating module 12 may also be located within the tube wall of the first tube body 21, that is, the first heating element 121 of the heating module 12 is embedded in the first tube body 21, so that certain protection can be provided by the first tube body 21, which is beneficial to extending the service life of the first heating element 121.

[0061] Exemplarily, the heating module 12 may be completely embedded in the tube wall of the first tube body 21; the heating module 12 may also be partially embedded in the tube wall of the first tube body 21. For example, the heating module 12 may be partially embedded in the outer tube wall of the first tube body 21, or for another example, the heating module 12 may be partially embedded in the inner tube wall of the first tube body 21.

[0062] As an example, the tube wall of the first tube body 21 may be a hollow structure to accommodate the first heating element 121 inside the tube wall of the first tube body 21.

[0063] As another example, the first tube body 21 may be a non-metal part, such as a plastic part. The first tube body 21 may be manufactured by injection molding, so that the first heating element 121 is located within the tube wall of the first tube body 21, making the heating module 12 and the first tube body 21 an integral whole.

[0064] In still other examples, the first tube body 21 may also be a metal part. The first tube body 21 and the first heating element 121 are of an integral structure.

[0065] Metal will generate heat after being electrified. When the first tube body 21 is set as a metal part and is of an integral structure with the first heating element 121, after the first heating element 121 is electrified, the first tube body 21 itself can generate heat to heat the air flow channel 21a. The first tube body 21 itself generates heat, and the heating range is larger, and a better heating effect can be produced on different regions of the air flow channel 21a.

[0066] As Figure 1 shown, the nozzle further includes a heat insulation layer 30, and the heat insulation layer 30 is located between the first tube body 21 and the outer shell 22. The heat insulation layer 30 surrounds the first tube body 21.

[0067] The heat insulation layer 30 is used to separate the first tube body 21 and the outer shell 22, preventing excessive heat from being conducted to the outer shell 22 and causing the temperature of the outer shell 22 to rise. This allows the outer shell 22 to remain at a relatively low temperature and prevents scalding of the user's mouth.

[0068] Exemplarily, the heat insulation layer 30 can be a silicone part. In other examples, the heat insulation layer 30 can also be a component made of other materials with good heat insulation capabilities.

[0069] As Figure 1 shown, the mouthpiece further includes a partition 211 located between the first tube body 21 and the outer shell 22. The partition 211 is connected to the first tube body 21 and the outer shell 22 respectively. The partition 211, the first tube body 21, and the outer shell 22 enclose an accommodation cavity 20b. The heat insulation layer 30 is located in the accommodation cavity 20b.

[0070] The partition 211 is used to shield the heat insulation layer 30 between the first tube body 21 and the outer shell 22, playing a protective role.

[0071] Exemplarily, the partition 211 can be annular. The partition 211 is sleeved outside the first tube body 21. The inner edge of the partition 211 is connected to the first tube body 21, and the outer edge of the partition 211 is connected to the outer shell 22.

[0072] The partition 211 can be fixedly connected to the first tube body 21. For example, the partition 211 and the first tube body 21 can be an integral structure. The partition 211 can be detachably connected to the outer shell 22 to facilitate the disassembly and assembly of the mouthpiece, or the partition 211 can be bonded to the outer shell 22.

[0073] As an example, the partition 211 can be a plastic part. In the atomizer, the partition 211 can also play a role in preventing the aerosol matrix in the liquid storage chamber from leaking.

[0074] Figure 2 is a cross-sectional schematic diagram of an atomizer provided by an embodiment of the present application. As Figure 2 shown, the atomizer includes a liquid storage assembly 100, an atomization assembly 300, and a mouthpiece 200. The mouthpiece 200 can be any of the aforementioned mouthpieces.

[0075] The liquid storage assembly 100 is used to store the aerosol matrix. The atomization assembly 300 is used to heat the aerosol matrix. Among them, the atomization assembly 300 is formed with an atomization channel 60a, and the atomization channel 60a is communicated with the air flow channel 21a. The aerosol formed after the aerosol matrix is heated flows through the air flow channel 21a from the atomization channel 60a and is released at the mouthpiece opening 20a.

[0076] In the embodiments of the present application, when the aerosol generating device is in use, during the process that the atomized aerosol matrix moves towards the mouthpiece opening 20a through the air flow channel 21a, since the heating module 12 can heat the air flow channel 21a, it is possible to maintain the atomized aerosol matrix in a gaseous state within the air flow channel 21a, avoiding the atomized aerosol matrix from liquefying due to cooling in the air flow channel 21a.

[0077] In some examples, the atomization assembly 300 includes a second heating element 80, and the second heating element 80 can be electrically connected to the heating module 12.

[0078] The second heating element 80 is heated by means of electricity. Connecting the heating module 12 and the second heating element 80 electrically means that when power is supplied to the second heating element 80 to make the second heating element 80 heat, the heating module 12 also starts to heat the air flow channel 21a, so that the heating of the air flow channel 21a and the heating of the aerosol matrix in the liquid guiding member 70 are carried out simultaneously.

[0079] The liquid storage assembly 100 may include a liquid storage housing 50. A liquid storage is formed inside the liquid storage housing 50, and the liquid storage is used to contain the aerosol matrix. In some examples, the liquid storage assembly 100 may further include a liquid storage member. For example, the liquid storage member may be a liquid storage cotton, and the liquid storage cotton adsorbs / soaks the aerosol matrix.

[0080] The atomization assembly 300 is located inside the liquid storage housing 50. As Figure 2 shown, the atomization assembly 300 further includes a bracket 60 and a liquid guiding member 70. The bracket 60 forms an atomization channel 60a, and the atomization channel 60a communicates with the air flow channel 21a. The liquid guiding member 70 and the second heating element 80 are located in the bracket 60.

[0081] The bracket 60 provides a space inside the liquid storage housing 50 to accommodate the liquid guiding member 70 and the second heating element 80. The bracket 60 can be tubular, and the tube wall of the bracket 60 can have structures such as holes and slits, so that the aerosol matrix in the liquid storage housing 50 can enter the atomization channel 60a and be absorbed by the liquid guiding member 70. The second heating element 80 is used to heat the aerosol matrix in the liquid guiding member 70 to vaporize the aerosol matrix. The aerosol matrix vaporized by the second heating element 80 can enter the air flow channel 21a and continue to flow towards the mouthpiece opening 20a. It is heated by the first tube body 21 in the air flow channel 21a, avoiding the liquefaction of the vaporized aerosol matrix after moving away from the second heating element 80.

[0082] As Figure 2 shown, the bracket 60 is inserted into the air flow channel 21a.

[0083] In some other examples, a part of the housing 20 is inserted into the bracket 60. For example, the first tube body 21 is inserted into the bracket 60.

[0084] The first tube body 21 and the bracket 60 are connected in a plug-in manner, which has a simple structure and is convenient for operation. The plug-in manner directly connects the air flow channel 21a of the first tube body 21 and the atomization channel 60a of the bracket 60, enabling the vaporized aerosol matrix in the bracket 60 to directly enter the first tube body 21.

[0085] As an example, as Figure 2 shown, the atomization assembly 300 further includes a connection wire 91. The connection wire 91 is in electrical contact with the heating module 12, and the connection wire 91 is connected to the second heating element 80.

[0086] Exemplarily, the connection wire 91 can be at least partially located on the surface of the bracket 60. In this example, the first electrode 122 is partially located on the surface of the first tube body 21, and the connection wire 91 is in electrical contact with the part of the first electrode 122 exposed outside the first tube body 21.

[0087] The first tube body 21 and the bracket 60 are physically and electrically connected by the mutual plug-in manner, which can supply power to the heating module 12, and has a simple structure and is easy to implement.

[0088] In this example, the connection wire 91 can be partially embedded in the bracket 60. One end of the connection wire 91 is located outside the bracket 60 and is in contact with the first electrode 122, and the other end of the connection wire 91 is located inside the bracket 60 and is connected to the second heating element 80.

[0089] As Figure 2 shown, the second heating element 80 can include a second heating body 81 and a second electrode 82. The second heating body 81 is located inside the bracket 60, and the connection wire 91 can be connected to the second heating body 81. The second electrode 82 is connected to the second heating body 81, and at least part of the second electrode 82 is exposed outside the liquid storage housing 50 to facilitate contact with the power supply, so that power can be supplied to the second heating body 81 and the first heating body 121 through the second electrode 82.

[0090] The material and structure of the second heating element 80 are not limited as long as it can play a heating role. Exemplarily, the second heating element 80 can include at least one of a heating mesh, a heating film, a heating wire, and a heating sheet.

[0091] As an example, in the embodiment of the present application, the second heating element 80 includes a heating coil. The heating coil is coaxially arranged with the atomization channel 60a.

[0092] When the second heating element 80 includes at least one of a heating sheet, a heating film, a heating mesh, and a heating wire, for example, the second heating element 80 can include a plurality of heating sheets arranged around the atomization channel 60a.

[0093] Figure 3 It is a cross-sectional schematic diagram of another atomizer provided by an embodiment of the present application. As Figure 3 shown, in this example, the atomization assembly 300 further includes a transition electrode 92, and one end of the transition electrode 92 is in electrical contact with the heating module 12. The other end of the transition electrode 92 is exposed on the outer surface of the atomizer.

[0094] By providing the transition electrode 92 to supply power to the first tube body 21, the first tube body 21 and the second heating element 80 are independently powered, which facilitates separately adjusting the heating power of the first tube body 21 and the heating power of the second heating element 80, so that the heating temperature can be adjusted more freely.

[0095] In this example, the transition electrode 92 can be partially embedded in the bracket 60, one end of the transition electrode 92 is exposed on the outer side wall of the bracket 60, and the exposed part is in electrical contact with the first electrode 122.

[0096] An embodiment of the present application also provides an aerosol generating device, which includes a power supply assembly and any one of the foregoing atomizers, and the power supply assembly is used to supply power to the atomization assembly 300 and / or the heating module 12 of the atomizer.

[0097] The power supply assembly can have a power supply terminal, and the power supply terminal can be in electrical contact with the second electrode 82 exposed outside the liquid storage housing 50, or can also be in electrical contact with the transition electrode 92, so as to supply power to the atomizer.

[0098] In some examples, the power supply assembly is detachably connected to the atomizer. For example, the power supply assembly can be detachably connected to the side of the liquid storage housing 50 away from the mouthpiece 200. Since the power supply assembly is detachably connected to the atomizer, it is convenient to replace the atomizer.

[0099] In some other examples, the power supply assembly and the atomizer can be fixedly connected. For example, the housing part of the power supply assembly and the liquid storage housing 50 of the atomizer are of an integral structure.

[0100] As an example, the aerosol generating device may further include a housing, and both the power supply assembly and the atomizer are located in the housing.

[0101] The above-described embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be included in the protection scope of the present application.
