As shown in fig. 4 to 6, the leaked liquid collecting chamber 43 and the inductor accommodating chamber 44 are both located between the partition plate 41 and the atomizing groove 42. Wherein the weep collection cavity 43 is adapted to collect aerosol-generating substrate and aerosol condensate that seeps out of the first vent 422 within the atomization tank 42 to avoid damage to the battery 6 by the seeped aerosol-generating substrate and aerosol condensate entering the battery receiving cavity.

Specifically, as shown in fig. 3 and 4, the opening of the leaked liquid collecting cavity 43 is disposed toward the inner side wall of the first housing 11, and the sealing cover 433 is disposed at the opening of the leaked liquid collecting cavity 43 and elastically abuts against the opening of the leaked liquid collecting cavity 43 to seal the leaked liquid collecting cavity 43; after the atomization is finished, the residual aerosol diffused into the leaked liquid collecting cavity 43 can be prevented from diffusing to other places to be condensed, and accordingly the leakage of the aerosol condensate can be better prevented. The sealing cover 433 is provided with a second air inlet hole 4331, a first end of the second air inlet hole 4331 is communicated with the first air inlet hole 111, and the second air inlet hole 4331 extends along the radial direction of the atomizing base 4; the second ends of the second air inlet holes 4331 are communicated with the leaked liquid collecting cavity 43; in a specific embodiment, when a user inhales the aerosol, the external air flow enters the leakage collecting chamber 43 through the first air inlet hole 111 and the second air inlet hole 4331 in sequence, and then enters the atomization chamber through the first vent hole 422.

Further, as shown in fig. 2, in order to better seal the leakage collecting cavity 43, the aerosol generating device may further include a first sealing ring 7a and a second sealing ring 7b, the first sealing ring 7a and the second sealing ring 7b are both disposed at the outer circumferential surface of the atomizing base 4, and the leakage collecting cavity 43 is located between the first sealing ring 7a and the second sealing ring 7b, so as to further seal the leakage collecting cavity 43 through the first sealing ring 7a and the second sealing ring 7 b. Specifically, as shown in fig. 5, a sealing groove 429a and a sealing groove 429b are formed in the outer side wall of the atomizing base 4, and the first sealing ring 7a is clamped in the sealing groove 429a for fixation; the second seal ring 7b is snap-fitted into the seal groove 429b for fixation.

Wherein the aerosol-generating substrate or aerosol condensate is prevented from escaping from the weep collection cavity 43 in order to further enhance the liquid-locking effect of the weep collection cavity 43. In a specific embodiment, referring to fig. 7, fig. 7 is a schematic structural view of an atomizing base provided in another embodiment of the present application; a plurality of capillary grooves 431 may be further provided at the cavity wall of the leakage collecting cavity 43 to lock the liquid by the capillary force of the capillary grooves 431.

Wherein the absorbing member 432 can be a cotton cloth, sponge, or other liquid absorbing member.

Referring to fig. 1 to 3, the inductor receiving cavity 44 is used for accommodating the airflow inductor 5; compare in current scheme, airflow inductor 5 installs on atomizing base 4, rather than installing on the support that is used for installing battery 6, therefore airflow inductor 5 is nearer apart from the distance in atomizing chamber, can effectively improve airflow inductor 5's sensitivity, and overall structure is compacter moreover, does benefit to aerosol and generates the miniaturization of device, and the user of being convenient for carries. In a specific embodiment, the opening of the inductor accommodating cavity 44 is disposed facing the inner side wall of the first housing 11, and the airflow inductor 5 is detachably disposed in the inductor accommodating cavity 44; thus, the airflow sensor 5 is convenient to recycle and is environment-friendly. Specifically, the radial direction of the airflow sensor 5 and the radial direction of the atomizing base 4 are obliquely arranged at a certain angle, that is, the radial direction of the airflow sensor 5 is not parallel to the radial direction of the atomizing base 4; this prevents the airflow sensor 5 from becoming soaked with aerosol-generating substrate or aerosol condensate, thereby further protecting the airflow sensor 5. Wherein, the inclination angle can be larger than 0 degree and smaller than or equal to 90 degrees. In a particular embodiment, the radial direction of the airflow sensor 5 is perpendicular to the radial direction of the atomizing base 4, as shown in fig. 3.

In a specific embodiment, the linear distance between the leaked liquid collecting cavity 43 and the atomizing core 3 is not less than the linear distance between the inductor accommodating cavity 44 and the atomizing core 3; this enables aerosol condensate or aerosol-generating substrate to flow under its own weight towards the leakage collection chamber 43 when present in the sensor receiving chamber 44, reducing the build-up of aerosol condensate or aerosol-generating substrate in the sensor receiving chamber 44, thereby acting to protect the airflow sensor 5 disposed within the sensor receiving chamber 44. Wherein, the straight-line distance that chamber 43 and inductor were collected to the weeping holds chamber 44 and atomizing core 3 all indicates along the axial direction D of atomizing base 4, corresponds the lateral wall that the cavity kept away from atomizing core 3 and the planar vertical distance of atomizing core 3 place.

In a specific embodiment, the leaked liquid collecting cavity 43 and the inductor accommodating cavity 44 are arranged at intervals along the circumferential direction of the atomizing base 4, and the distance between the leaked liquid collecting cavity 43 and the inductor accommodating cavity 44 and the linear distance between the leaked liquid collecting cavity and the atomizing core 3 are the same, that is, the leaked liquid collecting cavity 43 and the inductor accommodating cavity 44 are arranged in parallel along the radial direction of the atomizing base 4; therefore, the processing is convenient, the product structure is compact, and the product volume can be smaller. Specifically, referring to fig. 4 and 5, the bottom wall of the atomizing groove 42 is spaced from the partition plate 41 and connected thereto by a baffle plate 45; the baffle 45 divides the space between the bottom wall of the atomization tank 42 and the partition plate 41 into two parts, the first part is used as the leaked liquid collection cavity 43, the second part is used for arranging the inductor accommodating cavity 44, and the baffle 45 is also used as the side wall of the leaked liquid collection cavity 43 and the bottom wall of the inductor accommodating cavity 44. It is understood that in this embodiment, the straight distances of the leakage liquid collecting chamber 43 and the inductor accommodating chamber 44 from the atomizing core 3 are both perpendicular distances of the partition plate 41 from the plane of the atomizing core 3.

In the embodiment, as shown in fig. 4, the baffle 45 is further provided with a second vent hole 451, and the second vent hole 451 is communicated with the leaked liquid collecting cavity 43 and the sensor accommodating cavity 44 and serves as an air pressure trigger passage for the operation of the air flow sensor 5 installed in the sensor accommodating cavity 44. Wherein, the inductor holds chamber 44 and first air vent 422 intercommunication through second air vent 451 and weeping collection chamber 43, and then communicates atomizing groove 42, compares in the scheme that first air vent 422 directly communicates atomizing groove 42 and inductor and hold chamber 44, not only can trigger air current inductor 5 work when the user sucks, and can prevent to hold chamber 44 through the direct inductor that gets into of aerosol generation matrix or aerosol condensate of first air vent 422 seepage, leads to the problem of air current inductor 5 damage to take place. Preferably, the first ventilation aperture 422 extends in the axial direction D of the nebulizing base 4 and the second ventilation aperture 451 extends in the radial direction of the nebulizing base 4, thus avoiding the direct ingress of the leaking aerosol-generating substrate or aerosol condensate into the sensor housing chamber 44.

Specifically, when the aerosol generating device is placed vertically, that is, along the axial direction D of the atomizing base 4, the perpendicular distance between the second vent hole 451 and the plane of the atomizing core 3 is smaller than the perpendicular distance between the bottom wall of the leaked liquid collecting cavity 43 (i.e., the partition plate 41) and the plane of the atomizing core 3; thus, when the aerosol-generating device is used, the problem that the aerosol-generating substrate or aerosol condensate collected in the leakage collecting cavity 43 overflows into the inductor accommodating cavity 44 through the second vent holes 451 can be effectively avoided, and the air flow inductor 5 is prevented from being damaged. Further, the second vent hole 451 may be disposed proximate to the first vent hole 422; therefore, when the first vent 422 has airflow passing through, the airflow sensor 5 can be triggered to work quickly, and the sensitivity of the airflow sensor 5 can be effectively improved.

In an embodiment, referring to fig. 4 and 9, fig. 9 is a schematic view of a second venting hole and a connecting hole provided in an embodiment of the present application; the second vent hole 451 specifically includes a first vent section 451a and a second vent section 451b that communicate with each other.

The second vent hole 451 includes the first vent section 451a and the second vent section 451b arranged at a certain included angle, so that a vent path of the second vent hole 451 can be extended, aerosol diffusing into the second vent hole 451 when the aerosol generating device operates can form condensate in the second vent hole 451 as much as possible, and damage rate of the airflow sensor 5 caused by diffusion of residual aerosol into the sensor accommodating cavity 44 can be effectively reduced. In one embodiment, the second venting section 451b is perpendicular to the first venting section 451 a; and as shown in fig. 5 and 9, a connecting hole 452 is further formed by extending the end of the second vent section 451b facing away from the inductor receiving cavity 44.
