References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0032] like Figures 1 to 9 As shown, an embodiment of the present application proposes an aerosol generating device 100, comprising: an atomizer, the atomizer comprising an atomizer housing 26; an airflow sensor 1; a structural member 2, the structural member 2 being arranged on one side of the atomizer housing 26 along the first direction X, the structural member 2 being provided with a receiving chamber 9 and a condensation chamber 27, and the orthographic projections of the receiving chamber 9 and the condensation chamber 27 along the first direction X do not overlap, and the airflow sensor 1 is accommodated in the receiving chamber 9; a receiving groove 28 is provided at one end of the atomizer housing 26 facing the structural member, an air inlet 4 of the atomizer is provided at the bottom of the receiving groove 28, the structural member 2 is accommodated in the receiving groove 28, and a condensation hole 5 is provided on the side of the condensation chamber 27 facing away from the atomizer housing 26, and the condensation hole 5 is communicated with the air inlet 4 of the atomizer.

[0033] In the embodiment of the present application, a structural member 2 is provided on one side of the atomizer housing 26 along a first direction X, a receiving chamber 9 and a condensation chamber 27 are provided on the structural member 2, and the orthographic projections of the receiving chamber 9 and the condensation chamber 27 along the first direction X do not overlap, and the airflow sensor 1 is accommodated in the receiving chamber 9; a receiving groove 28 is provided on the end of the atomizer housing 26 facing the structural member, and the air inlet 4 of the atomizer is provided at the bottom of the receiving groove 28. The structural member 2 is accommodated in the receiving groove 28, and a condensation hole 5 is provided on the side of the condensation chamber 27 facing away from the atomizer housing 26, and the condensation hole 5 is connected to the air inlet 4 of the atomizer. In this way, by providing the receiving chamber 9 and the condensation chamber 27 in the structural member 2, whose projections do not overlap, the airflow sensor 1 is arranged in the receiving chamber 9, so that the receiving chamber 9 is used to limit the flow of condensate into the airflow sensor 1, thereby avoiding the problem of condensate damaging the airflow sensor 1 and causing the airflow sensor 1 to start automatically. In addition, the condensation hole 5 is connected to the air inlet 4 so that the condensate in the air inlet 4 can flow directly into the condensation hole 5 , thereby preventing the condensate from remaining in the condensation chamber 27 .

[0034] It should be noted that if Figure 2 and Figure 3 As shown, the first direction is the direction along the X axis, the second direction is the direction along the Y axis, and the third direction is the direction along the Z axis.

[0035] The projections of the accommodating chamber 9 and the condensing chamber 27 do not overlap, which means that the projection of the accommodating chamber 9 along the first direction X on the atomizer housing 26 and the projection of the condensing chamber 27 along the first direction X on the atomizer housing 26 are staggered.

[0036] In some embodiments, the accommodating chamber 9 can be provided on the side of the structural member 2 facing away from the atomizer housing 26, and the condensing chamber 27 can be provided on the side of the structural member 2 close to the atomizer housing 26. In this way, by separating the accommodating chamber 9 and the condensing chamber 27 from each other, the airflow sensor 1 and the condensing chamber 27 are separated from each other, thereby preventing condensate in the condensing chamber 27 from flowing into the airflow sensor 1, thereby damaging the airflow sensor 1.

[0037] In some embodiments, as Figure 9 As shown, the receiving groove 28 provided at the bottom of the atomizer housing 26 can be integrally formed with the atomizer housing 26, and the structural member 2 is assembled between the receiving groove 28 and the atomizer housing 26 to form a seal. This saves on the one hand the sealing silicone and bracket structures; on the other hand, this arrangement is simple in structure, easy to implement, and less prone to oil leakage.

[0038] In some embodiments, as Figure 2 and Figure 8As shown, the airflow sensor 1 and the structural member 2 are arranged at the air inlet end of the air inlet 4, and the atomizer core 32 is arranged at the air outlet end of the air inlet 4. In this way, the airflow sensor 1 and the structural member 2 are as close as possible to the atomizer core 32, so that the airflow sensor 1 is more sensitive and responds faster when the user draws.

[0039] It should be noted that the airflow sensor 1 can be a thermal gas sensor, an electrochemical gas sensor, a magnetic gas sensor, an optical gas sensor, a semiconductor gas sensor, etc.; the structural component 2 can be made of materials such as silicone, rubber, thermosetting elastomer, thermoplastic elastomer, etc.

[0040] One embodiment, such as Figure 4 As shown, the side of the structural member 2 facing the atomizer housing 26 is provided with a first groove 7 and a second groove 8 that are interconnected, and the first groove bottom of the first groove 7 is higher than the second groove bottom of the second groove 8 to form a step portion 6; the second groove 8 and the atomizer housing 26 enclose a condensation chamber 27, and the first groove 7 connects the condensation chamber 27 and the accommodating chamber 9, and the lower side of the step portion 6 is connected to the second groove 8, and the higher side of the step portion 6 is connected to the first groove 7.

[0041] In the embodiment of the present application, a first groove 7 and a second groove 8 are provided in the structural member 2, the first groove bottom of the first groove 7 being higher than the second groove bottom of the second groove 8, thereby forming a step 6. The second groove 8 and the atomizer housing 26 enclose a condensation chamber 27, and the first groove 7 connects the condensation chamber 27 with the accommodating chamber 9. Thus, the step 6 prevents condensate from flowing from the second groove 8 into the first groove 7, thereby preventing the airflow sensor 1 from coming into contact with the condensate and being damaged.

[0042] In some embodiments, the atomizer housing 26 covers the notch of the first groove 7 and the notch of the second groove 8, so that the first groove 7 and the atomizer housing 26 enclose a sensing channel, and the second groove 8 and the atomizer housing 26 enclose a condensation chamber 27. In this way, by enclosing the atomizer housing 26 with the first groove 7 and the second groove 8 to form the sensing channel and the condensation chamber 27, respectively, it is easier to process the structural member 2 than to process a closed sensing channel and condensation chamber 27, thereby reducing production costs.

[0043] In some embodiments, as Figure 2 As shown, the condensation chamber 27 is also used for air intake of the atomizer. One end of the sensing channel is connected to the condensation chamber 27, and the other end is connected to the airflow sensor 1. The sensing channel is used to trigger the airflow sensor 1 to work.

[0044] It should be noted that the sensing channel and the condensation chamber 27 in the structural member 2 can be set to a structure in which all positions are closed except for the opening at the connection; of course, the sensing channel and the air intake channel in the structural member 2 can also be set to a structure formed by the first groove 7 and the second groove 8 in the present application, respectively, and the atomizer housing 26.

[0045] One embodiment, such as Figure 2 、 Figure 4 and Figure 5 As shown, the first groove bottom 24 is provided with a first air hole 10 , and the first air hole 10 is communicated with the airflow sensor 1 .

[0046] In the embodiment of the present application, a first air hole 10 is provided at the first groove bottom 24, and the first air hole 10 is in communication with the airflow sensor 1. Thus, by providing the first air hole 10 in communication with the airflow sensor 1, the airflow in the accommodating chamber 9 flows out from the first air hole 10 to form a triggering airflow 19, thereby triggering the operation of the airflow sensor 1.

[0047] One embodiment, such as Figure 4 As shown, a protrusion 11 is provided on the side of the first air hole 10 facing the first groove bottom 24 , and the protrusion 11 is at least partially arranged around the first air hole 10 .

[0048] In the embodiment of the present application, a protrusion 11 is provided on the side of the first air hole 10 facing the first groove bottom 24, and the protrusion 11 is at least partially arranged around the first air hole 10. In this way, the protrusion 11 can prevent condensation from flowing from the first air hole 10 into the airflow sensor 1, thereby preventing damage to the airflow sensor 1.

[0049] In some embodiments, an overflow groove may be provided around the protrusion 11, the overflow groove being provided around the protrusion 11 and being connected to the sensing channel. In this way, the overflow groove may retain condensate and prevent the condensate from flowing out of the first air hole 10.

[0050] One embodiment, such as Figure 4 As shown, the first groove 7 has a first notch opening arranged opposite to the first groove bottom 24 , and the distance from the first groove bottom 24 to the first notch opening gradually increases from the first air hole 10 to the step portion 6 .

[0051] In the embodiment of the present application, the distance from the first groove bottom 24 to the first notch gradually increases from the first air hole 10 to the step 6. This facilitates the flow of condensate from the first air hole 10 to the step 6, thereby preventing the condensate from flowing back from the step 6 to the first air hole 10 and contacting the airflow sensor 1, thereby damaging the airflow sensor 1.

[0052] In some embodiments, as Figure 4As shown, a step 21 is provided in the middle portion of the first groove 7. In this way, a speed difference is generated when the condensate flows at the step 21 at the bottom of the first groove, so that the condensate flows into the condensation hole 5 faster.

[0053] One embodiment, such as Figure 4 As shown, the sensing channel curve extends.

[0054] In the embodiment of the present application, the sensing channel is extended along a curve. Thus, in the event of aerosol backflow, the length of the sensing channel is increased, so that the aerosol is less likely to pass through the sensing channel and enter the first air hole 10, thereby effectively preventing the airflow sensor 1 from being damaged or self-activated due to aerosol backflow.

[0055] One embodiment, such as Figures 2 to 4 As shown, the second groove bottom 25 is provided with a second air hole 14 , the second air hole 14 is spaced apart from the condensation hole 5 , and the second air hole 14 is communicated with the air inlet 4 .

[0056] In the embodiment of the present application, a second air hole 14 is provided at the bottom of the second tank, and the second air hole 14 is spaced apart from the condensation hole 5. This allows airflow to pass through the second air hole 14 and enter the air inlet 4 to form the intake airflow 20. Furthermore, by spacing the second air hole 14 apart from the condensation hole 5, the direction of the intake airflow 20 is separated from the direction of the condensate flow, thereby preventing the problem of gas-liquid mixing and contamination of the intake airflow 20.

[0057] In one embodiment, the second groove 8 has a second notch opening arranged opposite to the second groove bottom 25 , and the distance from the second groove bottom 25 to the second notch opening gradually increases from the second air hole 14 to the condensation hole 5 .

[0058] In the embodiment of the present application, the distance from the second groove bottom 25 to the second notch gradually increases from the second air hole 14 to the condensation hole 5. This facilitates the flow of condensate from the second air hole 14 to the condensation hole 5, preventing the condensate from flowing back from the condensation hole 5 to the second air hole 14 and damaging other components installed at the second air hole 14, such as the circuit board 12, the battery cell 22, and other components.

[0059] One embodiment, such as Figure 2 、 Figure 5 、 Figure 7 As shown, it also includes a circuit board 12 and a liquid absorption component 16; the circuit board 12 is arranged on the side of the structural component 2 away from the atomizer housing 26, and the airflow sensor 1 is arranged on the side of the circuit board 12 facing the structural component 2; a through hole is also provided at a position corresponding to the condensation hole 5 on the circuit board 12; the liquid absorption component 16 is arranged on the side of the circuit board 12 away from the structural component 2.

[0060] In the embodiment of the present application, the circuit board 12 is disposed on the side of the structural member 2 facing away from the atomizer housing 26, and the airflow sensor 1 is disposed on the side of the circuit board 12 facing the structural member 2. A through hole is also provided on the circuit board 12 at a position corresponding to the condensation hole 5. Thus, by providing a through hole corresponding to the condensation hole 5 on the circuit board 12, condensate can pass through the through hole to enter the liquid absorbing member 16, effectively preventing condensate from clogging the air inlet and causing poor suction. Furthermore, the liquid absorbing member 16 can also prevent excessive condensate from accumulating at the condensation hole 5, causing the condensate to flow back into the second air hole 14 and the airflow sensor 1, thereby damaging the airflow sensor 1 and other components.

[0061] In some embodiments, as Figure 8 As shown, the aerosol generating device 100 further includes a battery core 22, the battery core 22 is electrically connected to the circuit board 12, and the atomizing core 32 is electrically connected to the circuit board 12. The battery core 22 supplies power to the circuit board 12 to enable the atomizing core 32 to operate; Figure 4 As shown, when the user inhales, the trigger airflow 19 enters from the first air hole 10 of the structural member 2, passes through the second groove 8, and enters the air inlet 4 at the step 6; the trigger airflow 19 is used to trigger the airflow sensor 1 to work; after the airflow sensor 1 works, the signal is sent to the circuit board 12, and the circuit board 12 controls the atomization core 32 to heat and atomize the atomization matrix according to the signal.

[0062] One embodiment, such as Figure 2 、 Figure 3 、 Figure 6 as well as Figure 7 As shown, it also includes a connecting member 13; the connecting member 13 is arranged on the side of the circuit board 12 away from the airflow sensor 1, and the connecting member 13 and the circuit board 12 are enclosed to form an air cavity, and a third air hole 15 is provided on the circuit board 12, and the air cavity is respectively connected to the third air hole 15 and the accommodating cavity 9.

[0063] In the embodiment of the present application, the connector 13 is positioned on the side of the circuit board 12 facing away from the airflow sensor 1. The connector 13 and the circuit board 12 enclose an air cavity, and the circuit board 12 is provided with a third air hole 15, which is connected to the third air hole 15 and the accommodating chamber 9. Thus, the third air hole 15, the air cavity, and the accommodating chamber 9 together constitute a portion of the triggering airflow 19. Compared to a method of directly opening a hole below the airflow sensor 1, this embodiment increases the length of this portion of the triggering airflow 19, making it difficult for backflowing aerosol to pass through the third air hole 15 and enter the accommodating chamber 9. This effectively minimizes the problem of aerosol backflow causing damage to the airflow sensor 1 or self-activation.

[0064] In some embodiments, as Figure 6As shown, a fourth air hole 18 is further provided on the circuit board 12 and communicates with the airflow sensor 1. A complete trigger airflow 19 flows in from the third air hole 15, then passes through the third air hole 15, the air cavity, the fourth air hole 18, the accommodating cavity 9, the first air hole 10, and finally flows out of the trigger channel.

[0065] In some embodiments, as Figure 3 As shown, the third air hole 15 is arranged on the left side of the air inlet channel. In this way, by separating the air inlet channel and the third air hole 15, even in the case of aerosol backflow, the aerosol is discharged from the first air hole 10 and will not enter the third air hole 15.

[0066] One embodiment, such as Figure 8 As shown, it also includes an atomizer assembly 3; the atomizer housing 26 extends in a direction away from the structural member 2 at the position of the air inlet 4 to form an air inlet channel 29; the air inlet channel 29 is connected to the atomizer assembly 3.

[0067] In the embodiment of the present application, an air inlet channel 29 is formed by extending the atomizer housing 26 away from the structural member 2, and the air inlet channel 29 is connected to the atomizer assembly 3. In this way, the intake air flow 20 can be connected to the air inlet channel 29 through the air inlet 4, providing air flow to the atomizer assembly 3, thereby facilitating the operation of the atomizer assembly 3.

[0068] In some embodiments, as Figure 8 As shown, the atomizer assembly 3 includes a mounting seat 31 and an atomizer core 32. The mounting seat 31 is connected to the air inlet 4, and the atomizer core 32 is arranged in the mounting seat 31; the aerosol generating device 100 also has an inhalation port 23, which is arranged on the side of the air inlet channel 29 away from the air inlet 4, and the user inhales the atomized matrix through the inhalation port 23.

[0069] In some embodiments, as Figure 8 As shown in FIG, after the user inhales, part of the aerosol will flow back along the air inlet channel 29, the air inlet 4, and the sensing channel into the air flow sensor 1, thereby causing damage to the air flow sensor 1. That is, the airflow direction formed by the aerosol backflow is different from the airflow direction formed by the aerosol backflow. Figure 8 At the same time, since the aerosol itself carries heat, during the aerosol backflow process, the aerosol is cooled to form condensation. When the airflow sensor 1 comes into contact with the condensation, it will be damaged and cause self-activation, affecting the user experience.

[0070] In some embodiments, as Figure 3 、 Figure 8 As shown, when the user inhales, the intake air flow 20 enters from the second air hole 14 of the structural member 2, passes through the air inlet 4, enters the air inlet channel 29, and finally flows out from the air inlet 23; wherein, the flow direction of the intake air flow 20 in the structural member 2 is as shown in FIG. Figure 3As shown by the arrows, the intake air flows into the second air hole 14 , passes through the intake channel 29 , enters the air intake port 4 , and then flows out of the air intake port 4 and enters the intake channel 29 .

[0071] The above specific examples are used to illustrate the present application, which is only used to help understand the present application and is not intended to limit the present application. For those skilled in the art of the present application, based on the concept of the present application, they can also make some simple deductions, modifications or substitutions.
