The nebulizer has an atomization channel formed within it, which is equipped with a heater. During inhalation, external air enters the atomization channel, and the heater atomizes the aerosol matrix stored within the nebulizer to form an aerosol. The aerosol is then discharged from the aerosol-generating device along with the air through the nebulizer's mouthpiece.

During the inhalation process, aerosols are formed in both atomization channels and enter the mouthpiece along with the air. This aerosol generating device with two atomization channels can accommodate two different aerosol matrices in the atomizer, so that two aerosols are formed during the inhalation process and the two aerosols are mixed with each other.

[0004] In the aerosol generating device of the related art, the amount of air discharged from the two atomization channels during the inhalation process often differs greatly, resulting in poor atomization effect in one of the atomization channels and unsatisfactory mixing effect.

[0037] Figure 1 This is a schematic diagram of the structure of an aerosol generating device. Figure 1 As shown, the aerosol generating device includes an atomizer 100 and a power supply assembly 200 , and the atomizer 100 is connected to the power supply assembly 200 .

[0038] Two atomization channels 100 a are formed inside the atomizer 100 , and both atomization channels 100 a are connected to the suction nozzle 101 of the atomizer 100 .

[0039] The connection base 201 of the power supply assembly 200 is connected to the atomizer 100 , and an air inlet channel 201 a is provided near the edge of the connection base 201 . The air inlet channel 201 a is connected to the outside of the aerosol generating device through an air inlet pipe 202 . Figure 1 The direction of the airflow is schematically shown by arrows. During the suction process, the air enters the air inlet pipe 202, and after being discharged from the air inlet channel 201a, it flows in the direction of the two atomization channels 100a in the gap between the atomizer 100 and the connecting seat 201, and then enters the two atomization channels 100a, bringing the aerosol generated in the two atomization channels 100a out of the mouthpiece 101. Since the air inlet channel 201a is arranged near the edge of the connecting seat 201, the airflow in the gap between the atomizer 100 and the connecting seat 201 will first pass through the atomization channel 100a closer to the air inlet channel 201a. As a result, under the action of the negative pressure generated by the suction, a large amount of airflow will preferentially enter the atomization channel 100a closer to the air inlet channel 201a, and a small amount of air that is not inhaled into the atomization channel 100a will continue to flow into the other atomization channel 100a. This results in a significant difference in the airflow rates in the two atomization channels 100a. The aerosol in the atomization channel 100a with a larger airflow rate can be carried out of the mouthpiece under the action of air, while the atomization channel 100a with a smaller airflow rate has a poor atomization effect and a small airflow rate, and can only carry a small amount of aerosol out of the mouthpiece 101. This results in a poor mixing effect of the aerosols generated in the two atomization channels 100a of the aerosol generating device, making it difficult to meet user requirements.

[0040] Figure 2 Schematic diagram of the structure of an aerosol generating device provided in an embodiment of the present application. Figure 2 As shown, the aerosol generating device includes a nebulizer 100 and a power supply assembly 200 for supplying power to the nebulizer 100 .

[0041] The atomizer 100 includes an atomizing assembly 10 , which is formed with two atomizing channels 100 a . The power supply assembly 200 includes a connecting seat 201 , which is connected to the atomizer 100 . Figure 3 Schematic diagram of the internal structure of an aerosol generating device provided in an embodiment of the present application. Figure 3 As shown, a first air inlet channel 2011 a is provided on a side of the connecting base 201 close to the atomizer 100 , and an outlet of the first air inlet channel 2011 a is located between the inlets of the two atomizing channels 100 a .

[0042] By setting a first air inlet channel 2011a on the side of the connecting base 201 of the power supply component 200 close to the atomizer 100, and arranging the outlet of the first air inlet channel 2011a between the inlets of the two atomization channels 100a of the atomizer 100, during the inhalation process, after the air is discharged through the first air inlet channel 2011a, it can flow to the two atomization channels 100a respectively, avoiding that most of the air flows into one of the atomization channels 100a, while only a small amount of air flows into the other atomization channel 100a, which is beneficial to reducing the difference in air volume between the two atomization channels 100a, so that both atomization channels 100a have better atomization effect, thereby improving the mixing effect of the two aerosols.

[0043] like Figure 2 and Figure 3 As shown, in this example, the aerosol generating device may further include a housing 300 and an end cap 400, with the atomizer 100 and the power supply assembly 200 located in the housing 300. One end of the housing 300 may have a mouthpiece 101, which is used to communicate with the atomizer 100. The end cap 400 is located at an end of the housing 300 away from the mouthpiece 101, and the end cap 400 is detachably connected to the housing 300, for example, by a snap-fit connection.

[0044] The nebulizer 100 may include a liquid tank housing 20 and an atomizing assembly 10 located in the liquid tank housing 20. The liquid tank housing 20 forms a liquid tank for accommodating an aerosol matrix. In this example, two liquid tanks are formed in the liquid tank housing 20. The liquid tank housing 20 may include a shell body 21, a top sealing cover 22 and a bottom sealing cover 23, and the top sealing cover 22 and the bottom sealing cover 23 are respectively sealed with the shell body 21. As an example, the top sealing cover 22 and the bottom sealing cover 23 can be elastic parts, thereby utilizing the elasticity of the top sealing cover 22 and the bottom sealing cover 23 to fit tightly with the shell body 21 to achieve sealing. For example, the top sealing cover 22 and the bottom sealing cover 23 can both be silicone parts.

[0045] The atomizer assembly 10 includes two subassemblies, one of which is housed in each liquid reservoir. The subassemblies include a liquid reservoir 11, a bracket 12, and a heater 13. The bracket 12 forms the atomizer channel 100a and is surrounded by the liquid reservoir 11. The heater 13 is located within the bracket 12.

[0046] The side of the top sealing cover 22 away from the bottom sealing cover 23 can be used to install the first liquid absorbent cotton 221. The top sealing cover 22 is provided with an air outlet corresponding to the atomization channel 100a, and the air outlet is used to connect the atomization channel 100a and the suction nozzle 101.

[0047] The subassembly may further include a connection terminal 131 , which may be provided through the bottom sealing cover 23 . One end of the connection terminal 131 is electrically connected to the heating element 13 , and the other end of the connection terminal 131 is used to electrically contact the power supply assembly 200 .

[0048] As an example, the subassembly may further include a liquid guiding member 14, a portion of which is located in the atomization channel 100a and arranged around the heating member 13, and another portion of the liquid guiding member 14 is located outside the atomization channel 100a, and the liquid guiding member 14 is used to allow the aerosol matrix to enter the atomization channel 100a.

[0049] The bottom sealing cover 23 has a second air inlet channel 23a and a third air inlet channel 23b. One end of the bracket 12 of one subassembly is inserted into the second air inlet channel 23a, so that the atomization channel 100a of the bracket 12 is connected to the second air inlet channel 23a. One end of the bracket 12 of the other subassembly is inserted into the third air inlet channel 23b, so that the atomization channel 100a of the bracket 12 is connected to the third air inlet channel 23b.

[0050] like Figure 2 As shown, the power supply assembly 200 may include a connection base 201 and a circuit structure, and the connection base 201 is used to connect with the atomizer 100.

[0051] The circuit structure may include a battery 31 , a circuit board 32 and a microphone 33 . The microphone 33 is disposed on the circuit board 32 , and the battery 31 is electrically connected to the circuit board 32 .

[0052] As an example, the circuit structure may further include a display screen 34 and a mainboard 35. The display screen 34 is electrically connected to the mainboard 35, and the mainboard 35 is electrically connected to the circuit board 32. One side of the housing 300 may have a display screen mounting opening 300a, in which the display screen 34 is mounted. A transparent cover plate 301 may also be mounted on the display screen mounting opening 300a.

[0053] Figure 4 This is a schematic diagram of the structure of a connecting socket provided in an embodiment of the present application. Figure 4 As shown, the connection base 201 may include a plate body 2011, which is arranged opposite to the atomizer 100. In this example, the plate body 2011 is arranged opposite to the bottom sealing cover 23, with a gap between them.

[0054] In some examples, a second absorbent cotton 231 and a sealing gasket 232 may be sandwiched between the plate body 2011 and the bottom sealing cover 23, wherein the sealing gasket 232 is located between the plate body 2011 and the second absorbent cotton 231. For example, the sealing gasket 232 may be a silicone gasket.

[0055] The aforementioned circuit board 32 can be located on a side of the plate body 2011 away from the atomizer 100. The microphone 33 is located on a side of the circuit board 32 close to the plate body 2011. The microphone 33 is used to detect the air pressure in the gap between the plate body 2011 and the bottom sealing cover 23.

[0056] The battery 31 can be located on a side of the circuit board 32 away from the board body 2011. The mainboard 35 is located on a side of the battery 31 away from the circuit board 32 and can be connected to the circuit board 32 via a flexible cable. The display screen 34 can also be connected to the mainboard 35 via a flexible cable.

[0057] The power supply assembly 200 may further include a connector bracket 401, which is located inside the end cap 400 and can be connected to the connector 201. A receiving space is formed between the connector bracket 401 and the connector 201 to accommodate at least part of the circuit structure, for example, the circuit board 32, the battery 31, and the mainboard 35.

[0058] Figure 5 This is a top view of a connection socket provided in an embodiment of the present application, as shown in FIG. Figure 5 As shown, the outlet of the first air inlet channel 2011 a is located in the middle of the plate body 2011 .

[0059] Since the outlet of the first air inlet channel 2011a is located in the middle of the plate body 2011, during the inhalation process, air enters the gap between the plate body 2011 and the atomizer 100 from the first air inlet channel 2011a, and is more likely to diffuse around the first air inlet channel 2011a, so that the air can be more evenly inhaled into the two atomizing channels 100a.

[0060] In some examples, the distances from the outlet of the first air inlet channel 2011 a to the inlets of the two atomizing channels 100 a are equal.

[0061] The closer the distance between the inlet of the atomizing channel 100a and the outlet of the first air inlet channel 2011a is, the easier it is for air to be drawn into the atomizing channel 100a. In this example, by making the distance between the outlet of the first air inlet channel 2011a and the inlet of the two atomizing channels 100a equal, it is helpful to further reduce the difference in the amount of air entering the two atomizing channels 100a.

[0062] like Figure 5 As shown, an air flow channel 201 b is formed in the connecting base 201 , one end of the air flow channel 201 b is communicated with the first air inlet channel 2011 a , and the other end extends to the edge of the connecting base 201 .

[0063] The first air inlet channel 2011a is located in the middle of the body 2011, some distance from the exterior of the aerosol generating device. By arranging an airflow channel 201b within the connector 201 and utilizing the airflow channel 201b as a transmission channel, air from outside the aerosol generating device can be transferred via the airflow channel 201b to the first air inlet channel 2011a, facilitating air intake into the aerosol generating device.

[0064] like Figure 5 As shown, at least one section of the air flow channel 201 b extends along the edge of the plate portion 2011 .

[0065] The atomizer assembly 10 is electrically connected to the circuit board 32 via a conductive post 321. The conductive post 321 is arranged to pass through the plate body 2011. One end of the conductive post 321 is electrically connected to the circuit board 32, and the other end is electrically connected to the atomizer assembly 10. For example, one end of the conductive post 321 can be welded to the circuit board 32, and the other end of the conductive post 321 can be electrically contacted with the connection terminal 131. The conductive post 321 is mainly distributed near the middle of the plate body 2011, close to the first air inlet channel 2011a, and there are fewer structures distributed at the edge of the plate body 2011. In this example, by making at least one section of the air flow channel 201b extend along the edge of the plate body 2011, the edge position of the plate body 2011 is fully utilized, and the space occupied by the air flow channel 201b in the middle of the plate body 2011 is reduced, thereby avoiding affecting the arrangement of the conductive post 321.

[0066] As an example, Figure 5 As shown, the air flow channel 201 b is U-shaped, and the middle portion of the air flow channel 201 b extends along the edge of the plate portion 2011 .

[0067] The two ends of the air flow channel 201 b are bent relative to each other, so that the air flow channel 201 b is U-shaped as a whole. A avoidance area is formed between the two ends of the air flow channel 201 b, providing space for the arrangement of the conductive pillars 321.

[0068] In some possible implementations, the air flow channel 201 b is located inside the plate body 2011 , that is, the plate body 2011 may be a hollow structure.

[0069] In this example, the air flow channel 201 b is located on a side of the plate body 2011 away from the atomizer 100 . Figure 6 This is a schematic diagram of the structure of a connection socket provided in an embodiment of the present application. Figure 6As shown, the connecting base 201 further includes a slot-like portion 2012, which is located on a side of the plate body 2011 away from the atomizer 100. The slot-like portion 2012 is connected to the plate body 2011. A groove is formed on a side of the slot-like portion 2012 close to the plate body 2011, and the groove and the plate body 2011 form an airflow channel 201b.

[0070] Because the airflow channel 201b is formed by the plate portion 2011 and the groove portion 2012, primarily utilizing the grooves of the groove portion 2012, the shape and structure of the plate portion 2011 are minimally altered, and the structural strength of the plate portion 2011 is minimally impacted. The thickness of the plate portion 2011 also does not need to be adjusted, which does not significantly increase the volume of the aerosol generating device and has minimal impact on the original manufacturing process.

[0071] In some examples, the groove portion 2012 may be welded to the plate body portion 2011 , for example, by ultrasonic welding.

[0072] As an example, the groove portion 2012 and the plate body 2011 are integrally formed. That is, the groove portion 2012 and the plate body 2011 can be manufactured using an integral molding process, such as injection molding. The groove portion 2012 and the plate body 2011 manufactured using the integral molding process are tightly connected, and the connection is not prone to air leakage.

[0073] Combine Figure 4 As shown, a notch 2012a is formed on one side of the airflow channel 201b. The connection base 201 further includes a sealing member 203, which is located in the notch 2012a.

[0074] By setting a notch 2012a on the side wall of the air flow channel 201b and sealing the notch 2012a with a seal 203, when cleaning is required or foreign matter enters the air flow channel 201b, the seal 203 can be removed and the air flow channel 201b can be cleaned through the notch 2012a or the foreign matter can be removed.

[0075] Furthermore, providing notches 2012a on the sidewalls of airflow channel 201b facilitates the use of injection molding to manufacture connector 201. For example, during the injection molding process for connector 201, an insert can be inserted into the mold cavity of an injection mold to form airflow channel 201b. After the injection molding process is complete, the insert is removed from the mold cavity, forming notches 2012a. In other words, notches 2012a facilitate the removal of the insert from airflow channel 201b during the injection molding process.

[0076] like Figure 6 As shown, the connection base 201 further includes an air inlet pipe 202, which is connected to the groove portion 2012. The air inlet pipe 202 is connected to the air flow channel 201b.

[0077] In this example, the air inlet pipe 202 is located on a side of the groove portion 2012 away from the plate portion 2011 , and one end of the air inlet pipe 202 is connected to the bottom of the groove of the groove portion 2012 .

[0078] By connecting the air inlet pipe 202 to the groove portion 2012 , the air inlet pipe 202 is connected to the air flow channel 201 b , so that during the suction process, air can enter the air flow channel 201 b through the air inlet pipe 202 .

[0079] As an example, see Figure 3 As shown, the air intake pipe 202 can extend to the end cap 400 and communicate with the outside world through a through-hole located on the end cap 400. The end cap 400 can also be provided with an adjustment key 41, which is slidably connected to the end cap 400 and is used to block the through-hole. By sliding the adjustment key 41, the area of the through-hole blocked by the adjustment key 41 is changed, thereby adjusting the difficulty of air intake through the air intake pipe 202. The larger the area of the through-hole blocked, the more difficult it is for the air intake pipe 202 to enter during the inhalation process, and the smaller the area of the through-hole blocked, the easier it is for the air intake pipe 202 to enter.

[0080] like Figure 3 As shown, a switch button 42 may also be provided on the end cover 400, and the switch button 42 may be used to control the opening or closing of the aerosol generating device.

[0081] 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 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. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present application, and should all be included in the scope of protection of the present application.
