[0042] In the embodiments of the present application, since the air passage piece 300 has the first air passage 310 and the second air passage 320, the first air passage 310 is used to communicate with the atomizing air passage 611 of the atomizer 600, the second air passage 320 is led out from the first air passage 310 and arranged intersecting with the first air passage 310, and the airflow sensor 200 is connected to the second air passage 320, so that the liquid in the atomizing air passage 611 is difficult to flow into the second air passage 320 from the first air passage 310, which helps to reduce the risk of failure of the airflow sensor 200 affected by the liquid.

[0043] Embodiments of the power supply assembly in the present application:

[0044] In one embodiment, referring to Figure 1 and Figure 2 , the power supply assembly includes a housing 100, an airflow sensor 200, an air passage piece 300, and components such as a power supply 400 as needed.

[0045] The housing 100 can be understood as a collection of related components that constitute the basic structural framework and outer contour form of the power supply assembly. With the help of the housing 100, the power supply assembly can be held, moved, operated and used.

[0046] Referring to Figure 1 and Figure 2 , the housing 100 is provided with a mounting cavity 110, and one end of the housing 100 is provided with a mounting portion 330 for mounting the atomizer 600. In some embodiments, the mounting cavity 110 can be provided with a mounting opening 111 at the end connected to the mounting portion 330, so as to mount the required parts into the mounting cavity 110 through the mounting opening 111. The mounting portion 330 can be configured to close the mounting cavity 110 when the atomizer 600 is mounted, i.e., the atomizer 600 serves as a cover for the mounting opening 111, which facilitates assembly and helps to save material costs.

[0047] Referring to Figure 1 , the airflow sensor 200 and the air passage piece 300 can be arranged in the mounting cavity 110. The air passage piece 300 is mainly arranged to provide a sensing air passage, so that the airflow sensor 200 and the atomizing air passage 611 of the atomizer 600 can communicate, so that the airflow sensor 200 can accurately sense the airflow change caused by the suction action, and then link the atomizing core in the atomizer 600 to start heating in time.

[0048] As can be understood by those skilled in the art, the atomizing air passage 611 of the atomizer 600 is prone to generate or enter liquid, which includes but is not limited to condensate generated by aerosol condensation, atomized liquid infiltrated into the atomizing air passage 611, and various liquids entering the atomizing air passage 611 by other means. The liquid in the atomizing air passage 611 is prone to enter the air flow sensor 200 through the sensing air passage in the air passage member 300, causing the air flow sensor 200 to short circuit and fail.

[0049] To this end, in an embodiment, as shown in Figure 3 , the air passage member 300 is provided with a first air passage 310 and a second air passage 320. The first air passage 310 is provided with an air inlet 311 at a side of the air passage member 300 away from the mounting portion 330 and an air outlet 312 at a side of the air passage member 300 close to the mounting portion 330. The air outlet 312 is configured to communicate with the atomizing air passage 611 of the atomizer 600 arranged on the mounting portion 330. The second air passage 320 is led out from the first air passage 310, and the air flow sensor 200 is connected to the second air passage 320. The second air passage 320 is arranged transversely to the first air passage 310 to limit the flow of liquid from the first air passage 310 into the second air passage 320.

[0050] By arranging the sensing air passage in the form of the first air passage 310 and the second air passage 320 intersecting with each other, even if the liquid in the atomizing air passage 611 flows back into the first air passage 310 through the air outlet 312, it can be discharged from the air inlet 311 and is difficult to enter the second air passage 320, which helps to reduce the possibility of the air flow sensor 200 being affected by the liquid and failing.

[0051] As can be understood by those skilled in the art, the transverse or inclined arrangement of the second air passage 320 relative to the first air passage 310 helps to limit the flow of liquid.

[0052] Therefore, in an embodiment, as shown in Figure 3 , the second air passage 320 can be arranged such that the distance from the communication position of the second air passage 320 with the first air passage 310 to the mounting portion 330 is equal to the distance from the connection position of the second air passage 320 with the air flow sensor 200 to the mounting portion 330, i.e. the second air passage 320 is arranged transversely to the mounting portion 330 in the view angle shown in Figure 3 .

[0053] In another embodiment, the second air passage 320 can also be arranged such that the communication position of the second air passage 320 with the first air passage 310 is closer to the mounting portion 330 than the connection position of the second air passage 320 with the air flow sensor 200, i.e. the connection position of the second air passage 320 with the air flow sensor 200 is higher than the communication position of the second air passage 320 with the first air passage 310.

[0054] In an embodiment, as shown in Figure 3, the first air passage 310 can include an air inlet section 313 and an air outlet section 314, the second air passage 320 is led from the middle of the air outlet section 314, the air inlet section 313 and the air outlet section 314 axially intersect, and the gas entering the air outlet section 314 from the air inlet section 313 has a turning angle of no more than 90°. The cooperation of the air inlet section 313 and the air outlet section 314 helps to guide the liquid flowing back into the first air passage 310 so that the liquid can be discharged from the air outlet section 314 at a required position. By limiting the turning angle between the air inlet section 313 and the air outlet section 314, it is helpful to avoid the formation of a liquid storage bend at the connection between the air inlet section 313 and the air outlet section 314, and facilitate smooth discharge of the liquid. Exemplarily, please refer to Figure 3 , the air inlet section 313 can be arranged along the axial direction of the mounting cavity 110, and the second air passage 320 and the air outlet section 314 can be arranged perpendicularly to the air inlet section 313. In other examples, the air outlet section 314 and the air inlet section 313 can also be arranged at other angles, which can meet the design and use requirements.

[0055] In a further embodiment, please refer to Figure 3 , one side of the air passage member 300 provided with the air inlet 311 can be arranged to be attached to the side wall of the shell 100, and the side wall of the shell 100 is provided with a flow guide through hole 130 corresponding to the air outlet 312, so that the liquid flowing back into the first air passage 310 is discharged to the outside of the shell 100 through the air outlet 312 and the flow guide through hole 130, to prevent the liquid from affecting other components or lines in the mounting cavity 110. Those skilled in the art can understand that the air passage member 300 can be made of elastic material, such as silicone or rubber, etc., to improve the sealing performance of the connection between the air inlet 311 and the flow guide through hole 130, and reduce the possibility of liquid leakage into the mounting cavity 110.

[0056] In an embodiment, please refer to Figure 3 and Figure 4 , the air passage member 300 can further be provided with a mounting portion 330 on one side, and the mounting portion 330 is provided with a containing cavity 331 capable of containing at least a sensing portion of the airflow sensor 200, and the containing cavity 331 is in communication with the second air passage 320. Exemplarily, the airflow sensor 200 is arranged on the circuit board 210, and the mounting portion 330 is integrally arranged on one side of the air passage member 300, and the mounting portion 330 covers the airflow sensor 200 in the containing cavity 331, which helps to avoid the airflow change in the mounting cavity 110 from triggering the airflow sensor 200 by mistake.

[0057] In an embodiment, please refer to Figure 3 and Figure 5The installation cavity 110 can further be provided with a partition 500 between the installation portion 330 and the air passage member 300, the partition 500 is used to separate the installation cavity 110, so that the transition cavity 510 is formed between the partition 500 and the installation portion 330; when the installation portion 330 is installed with the atomizer 600, the transition cavity 510 is in communication with the atomizing air passage 611 of the atomizer 600; the partition 500 is provided with a connecting through hole 520 corresponding to the air outlet 312, and the first air passage 310 is in communication with the transition cavity 510 through the connecting through hole 520.

[0058] The transition cavity 510 is formed by the partition 500, which can buffer the liquid flowing back in the atomizing air passage 611, increase the difficulty of the liquid entering the first air passage 310, and further reduce the risk of the airflow sensor 200 being affected by the liquid and failing.

[0059] In an embodiment, referring to Figure 3 and Figure 5 , the connecting through hole 520 is provided with a gas guide pipe 530, the gas guide pipe 530 has a first end and a second end, the first end is connected to the air outlet 312, so that the gas guide pipe 530 is in communication with the first air passage 310, the second end extends into the transition cavity 510, the end of the second end is closed, the sidewall of the second end is provided with a gas guide outlet 531, the gas guide outlet 531 is in communication with the transition cavity 510, and the gas guide outlet 531 has a spacing with the connecting through hole 520. By providing the gas guide pipe 530 to communicate the first air passage 310 and the transition cavity 510, since the gas guide outlet 531 is provided on the sidewall of the second end of the gas guide pipe 530 extending into the transition cavity 510, the height of the accumulated liquid in the transition cavity 510 reaching the gas guide outlet 531 can enter the gas guide pipe 530, which helps to reduce the gas resistance of the gas guide pipe 530 while further increasing the difficulty of the liquid entering the first air passage 310.

[0060] In order to avoid displacement of the gas guide pipe 530 relative to the connecting through hole 520 during use, so that the gas guide outlet 531 is blocked, in an embodiment, referring to Figure 3 and Figure 5 , the side of the connecting through hole 520 close to the installation portion 330 has a diameter expansion section 521, the outer diameter of the part of the gas guide pipe 530 located in the diameter expansion section 521 is adapted to the inner diameter of the diameter expansion section 521, for example, the outer diameter of the part of the gas guide pipe 530 located in the diameter expansion section 521 is set to be equal to or slightly smaller than the inner diameter of the diameter expansion section 521, so as to limit the movement of the gas guide pipe 530 in the direction close to the air passage member 300, and avoid blocking the gas guide outlet 531.

[0061] In another embodiment, referring to Figure 3 , the first end can be configured to be inserted into the air outlet 312, and a stepped surface 315 for limiting the first end is arranged in the first air passage 310, so as to limit the gas guide pipe 530.

[0062] Those skilled in the art can understand that, in some embodiments, both the stepped surface 315 for limiting the first end in the first air channel 310 and the enlarged section 521 on the side of the connecting through hole 520 close to the mounting portion 330 can be provided, and the structure of the portion of the air guide tube 530 located in the enlarged section 521 is adapted to the structure of the enlarged section 521, and the two settings cooperate to limit the air guide tube 530. Of course, other limiting structures or limiting forms can be used to limit the air guide tube 530, and any structure that can avoid blocking the air outlet 531 can be used.
