[0039] Referring to Figure 1 and Figure 2 As shown, the aerosol generating device involved in the embodiment of the present application includes: a base 100, a bracket 200, and a leak-proof member 300.

[0040] Specifically, the base 100 is provided with an air inlet channel 110; the bracket 200 is provided with an atomization channel 210; the leak-proof member 300 is disposed between the base 100 and the bracket 200. The leak-proof member 300 is provided with a ventilation hole 310, and the ventilation hole 310 is disposed in a staggered manner with the atomization channel 210. A gas guiding channel 400 is provided on the side of the leak-proof member 300 close to the base 100, and the air inlet channel 110 is communicated with the ventilation hole 310 through the gas guiding channel 400.

[0041] In the aerosol generating device provided by the present application, air can enter the aerosol generating device through the air inlet channel 110 of the base 100, then enter the ventilation hole 310 through the gas guiding channel 400, and finally enter the atomization channel 210 through the ventilation hole 310, so that the atomized aerosol matrix in the atomization channel 210 can be sucked by the user. In this process, since the ventilation hole 310 is arranged in a staggered manner with the atomization channel 210, the probability that the aerosol matrix and condensate in the atomization channel 210 enter the ventilation hole 310 can be reduced. Thus, the probability that the aerosol matrix and condensate in the above aerosol generating device leak out of the aerosol generating device through the air inlet channel 110 can be reduced, the probability that the aerosol matrix and condensate fall onto the power supply device can be reduced, and the damage to the power supply device can be reduced.

[0042] It should be noted that the power supply device and the aerosol generating device can be fixedly connected or detachably connected.

[0043] Refer to Figure 2 and Figure 3 As shown, the ventilation hole 310 is arranged in a staggered manner with the air inlet channel 110.

[0044] In this embodiment, since the ventilation hole 310 is arranged in a staggered manner with the air inlet channel 110, not only can the probability that the aerosol matrix and condensate in the atomization channel 210 enter the ventilation hole 310 be reduced, but also the probability that the aerosol matrix and condensate in the ventilation hole 310 enter the air inlet channel 110 can be reduced. Thus, the probability that the aerosol matrix and condensate in the above aerosol generating device leak out of the aerosol generating device through the air inlet hole can be further reduced, the probability that the aerosol matrix and condensate fall onto the power supply device can be reduced, and the damage to the power supply device can be reduced.

[0045] Refer to Figure 4 and Figure 7 As shown, one side of the base 100 close to the leak-proof member 300 has an air inlet portion 120, the air inlet channel 110 is opened in the air inlet portion 120, one side of the leak-proof member 300 close to the base 100 has a gas guiding portion 320, the gas guiding portion 320 is arranged in a staggered manner with the ventilation hole 310, and the gas guiding portion 320 is connected to the air outlet end of the air inlet portion 120 to define the gas guiding channel 400.

[0046] In this embodiment, an air guiding channel 400 can be defined between the air guiding part 320 and the air outlet end of the air inlet part 120, so that the gas in the air inlet channel 110 can enter the air guiding channel 400 through the air outlet end of the air inlet part 120, thereby realizing the air guiding function of the air guiding channel 400. Since the air guiding part 320 and the ventilation holes 310 are arranged in a dislocation manner, in this way, not only can the gas in the air guiding channel 400 enter the ventilation holes 310, but also the probability of the aerosol matrix and the condensate in the ventilation holes 310 entering the air guiding channel 400 can be reduced, thereby reducing the probability of the aerosol matrix and the condensate leaking out of the aerosol generating device through the air inlet holes.

[0047] Refer to Figure 5 and Figure 7 As shown, the air outlet end of the air inlet part 120 has an annular end face 121, and the air guiding part 320 has an arc-shaped end face 321. The annular end face 121 is connected to the arc-shaped end face 321, and the annular end face 121 and the arc-shaped end face 321 are arranged at an angle to define the air guiding channel 400.

[0048] Specifically, in this embodiment, the curvature of the arc-shaped end face 321 is the same as that of the annular end face 121, so that the arc-shaped end face 321 can fit with the annular end face 121.

[0049] In this embodiment, when the annular end face 121 is connected to the arc-shaped end face 321, the sealing performance of the air guiding channel 400 can be ensured. When the gas flows out of the air inlet channel 110 through the air outlet end of the air inlet part 120, most of the gas can enter the ventilation holes 310 through the air guiding channel 400, reducing the suction difficulty of the user. At the same time, when the gas enters the air guiding channel 400, the arc-shaped end face 321 can reduce the impact on the gas, so that the gas can flow evenly and smoothly in the air guiding channel 400, reducing the disturbance to the gas, improving the smoothness of the gas entering the ventilation holes 310 through the air guiding channel 400, further reducing the suction difficulty of the user, and improving the user experience.

[0050] Refer to Figure 4 、 Figure 5 and Figure 7 As shown, the number of the ventilation holes 310 is two, and the number of the air inlet channels 110 is two. The air guiding part 320 is located between the two air inlet channels 110, and each air inlet channel 110 is located between the two ventilation holes 310.

[0051] In this embodiment, since the air guiding part 320 is located between two air inlet channels 110, and each air inlet channel 110 is located between two ventilation holes 310, thus, each air inlet channel 110 can be arranged in a staggered manner with two ventilation holes 310, and at the same time, each air inlet channel 110 can be connected to two ventilation holes 310 through an air guiding channel 400, so that the gas in each air inlet channel 110 can enter the atomization channel 210 through two ventilation holes 310, thereby further reducing the suction difficulty of the user and improving the user experience.

[0052] Referring to Figure 3 As shown, a liquid injection hole 220 is further provided on the bracket 200, and the aerosol generating device further includes a liquid injection plug 500 adapted to the liquid injection hole 220, and the liquid injection plug 500 is used for sealing connection with the hole wall of the liquid injection hole 220.

[0053] In this embodiment, the liquid injection hole 220 is used to inject the aerosol matrix into the aerosol generating device for the user to inhale. Since the liquid injection plug 500 is used for sealing connection with the hole wall of the liquid injection hole 220, thus, during the assembly process, after the injection of the aerosol matrix is completed, the liquid injection hole 220 can be blocked by the liquid injection plug 500 to improve the sealing performance of the aerosol generating device to prevent the aerosol matrix inside the aerosol generating device from leaking from the liquid injection hole 220, reduce the damage to the power supply device, and at the same time improve the user experience.

[0054] Referring to Figure 5 and Figure 6 As shown, the liquid injection plug 500 and the leak-proof part 300 are of an integrally formed structure.

[0055] Specifically, referring to Figure 4 As shown, in this embodiment, the liquid injection plug 500 is arranged on the side of the leak-proof part 300 away from the base 100 to further improve the sealing performance of the liquid injection hole 220 through the leak-proof part 300, and prevent the aerosol generated in the aerosol generating device from directly leaking from the liquid injection hole 220 to the base 100.

[0056] In this embodiment, since the liquid injection plug 500 and the leak-proof part 300 are of an integrally formed structure, the number of assembled parts is reduced, which helps to improve the production efficiency. In addition, after long-term use, even if the aerosol matrix seeps out between the liquid injection plug 500 and the liquid injection hole 220, the seeping aerosol matrix can fall onto the leak-proof part 300, and at the same time, it can also prevent the aerosol matrix falling onto the leak-proof part 300 from penetrating through the gap between the liquid injection plug 500 and the leak-proof part 300 to the base 100, reducing the possibility of the aerosol matrix penetrating out of the aerosol generating device from the base 100. Thus, the sealing performance of the aerosol generating device can be further improved through the integrally formed liquid injection plug 500 and leak-proof part 300.

[0057] Referring to Figures 3 to 6 As shown, on one side of the leak-proof member 300 close to the bracket 200, there is a liquid accumulation groove 330, and the liquid accumulation groove 330 is adjacently arranged to the ventilation hole 310.

[0058] Specifically, referring to Figure 2 As shown, in this embodiment, the liquid accumulation groove 330 is communicated with the atomization channel 210, so that the aerosol matrix and the condensate in the atomization channel 210 can fall into the liquid accumulation groove 330.

[0059] In this embodiment, since there is a liquid accumulation groove 330 on one side of the leak-proof member 300 close to the bracket 200, and the liquid accumulation groove 330 is adjacently arranged to the ventilation hole 310, thus, when the aerosol matrix and the condensate fall from the atomization channel 210 onto the leak-proof member 300, a certain buffer space can be provided for the aerosol matrix and the condensate through the liquid accumulation groove 330, so that the aerosol matrix and the condensate dripping from the atomization channel 210 can accumulate in the liquid accumulation groove 330, further reducing the possibility of the aerosol matrix and the condensate leaking from the ventilation hole 310 onto the base 100, and at the same time, reducing the possibility of the aerosol matrix and the condensate leaking from the edge of the leak-proof member 300 onto the base 100, thereby reducing the possibility of the aerosol matrix and the condensate leaking out of the aerosol generating device.

[0060] Specifically, referring to Figure 6 As shown, in this embodiment, the side groove wall of the liquid accumulation groove 330 close to the ventilation hole 310 is inclined, and the end of the side groove wall far from the groove bottom is close to the ventilation hole 310, and the end of the side groove wall close to the groove bottom is far from the ventilation hole 310. Thus, a downward sliding slope can be formed through this side groove wall, so that the aerosol matrix and the condensate dripping between the ventilation hole 310 and the liquid accumulation groove 330 can more easily enter the liquid accumulation groove 330, thereby reducing the probability of entering the ventilation hole 310.

[0061] Referring to Figure 2 and Figure 3 As shown, the aerosol generating device further includes an atomization assembly 600. The bracket 200 is provided with a connection channel 230 communicated with the ventilation hole 310. The atomization assembly 600 is arranged in the connection channel 230, and the atomization channel 210 flows through the atomization assembly 600.

[0062] Specifically, referring to Figure 2 As shown, in this embodiment, the atomization channel 210 is opened in the atomization assembly 600 to improve the atomization effect on the aerosol matrix.

[0063] In this embodiment, the atomization component 600 can be arranged in the connection channel 230 of the bracket 200 to fix the atomization component 600. At the same time, the atomization channel 210 can be communicated with the ventilation hole 310 through the connection channel 230, so that the gas in the ventilation hole 310 can enter the atomization channel 210 through the connection channel 230, and the aerosol matrix can be atomized by the atomization component 600. Further, when the aerosol matrix and the condensate drip from the atomization channel 210, the aerosol matrix and the condensate can drip into the connection channel 230, avoiding the aerosol matrix and the condensate from directly dripping into the ventilation hole 310, and further reducing the possibility of the aerosol matrix and the condensate leaking out of the aerosol generating device.

[0064] Referring to Figure 2 As shown, the aerosol generating device further includes a seal 700, and the atomization component 600 is sealingly connected to the inner wall of the connection channel 230 through the seal 700.

[0065] Specifically, referring to Figure 2 As shown, in this embodiment, the top and bottom of the atomization component 600 are respectively sealingly connected to the inner wall of the connection channel 230 through the seal 700, so that the gas in the ventilation hole 310 can enter the atomization channel 210 through the connection channel 230, avoiding the gas from entering the gap between the atomization component 600 and the inner wall of the connection channel 230, improving the gas utilization rate, reducing the suction difficulty of the user. Similarly, when the gas flows out of the atomization component 600 from the gas outlet end of the atomization component 600, the gas can also be prevented from entering the gap between the atomization component 600 and the inner wall of the connection channel 230. In this way, the utilization rate of the aerosol matrix can be improved, the atomization effect can be improved, so that most of the aerosol matrix can be inhaled by the user.

[0066] In this embodiment, since the atomization component 600 is sealingly connected to the inner wall of the connection channel 230 through the seal 700, in this way, it can be ensured that the gas enters the atomization channel 210 through the ventilation hole 310, avoiding the gas from entering the gap between the atomization component 600 and the inner wall of the connection channel 230. This can not only improve the gas utilization rate and reduce the suction difficulty of the user, but also improve the utilization rate of the aerosol matrix and improve the atomization effect, so that most of the aerosol matrix can be inhaled by the user.

[0067] Referring to Figure 3 and Figure 4 As shown, the aerosol generating device further includes a liquid absorbing member 800. The liquid absorbing member 800 is arranged in the base 100, and the projection of the ventilation hole 310 in its axial direction falls on the liquid absorbing member 800.

[0068] In this embodiment, even if the aerosol matrix and the condensate enter the ventilation holes 310, the aerosol matrix and the condensate can drip from the ventilation holes 310 onto the liquid absorbent member 800, and then the liquid absorbent member 800 can absorb the aerosol matrix and the condensate. In this way, the possibility of the aerosol matrix and the condensate leaking out of the aerosol generating device from the base 100 can be further reduced.
