The formed aerosol flows out through the aerosol flow through the slot 23, the second outlet channel 22 and the first outlet channel 122 in that order.

In an embodiment, referring to fig. 2, the fixing base 4 is located between the liquid storage cavity 121 and the battery accommodating cavity along the axial direction D. Referring to fig. 1 and 4, the fixing base 4 specifically includes a first air inlet hole 40, an atomization groove 42, a leakage collecting cavity 43, a sealing cover 433, an inductor accommodating cavity 44, and a first air supply hole 422. As shown in fig. 1 to 3, the atomizing groove 42 is located on one side of the fixing base 4 facing the liquid storage cavity 121, and the atomizing core 3 is located in the atomizing groove 42, so that the overall structure of the electronic atomizing device is simple. The atomizing support 2 is specifically covered and arranged at one end of the atomizing groove 42 departing from the battery accommodating cavity and extends into the atomizing groove 42, and the bottom of the atomizing support 2 is matched with the groove wall of the atomizing groove 42 to form an atomizing cavity. In a particular embodiment, as shown in figure 6, the bottom wall of the nebulization channel 42 is further formed with a locking reservoir 421 for storing the aerosol-generating substrate or aerosol condensate within the nebulization chamber.

As shown in fig. 4, the first air supply hole 422 is opened in the bottom wall of the atomization tank 42 and is located between the atomization tank 42 and the leaked liquid collection chamber 43 to communicate the atomization tank 42 and the leaked liquid collection chamber 43. In a specific embodiment, referring to fig. 6, in the vertical direction of the electronic atomization device, that is, along the axial direction D of the fixing base 4, the first air supply hole 422 extends toward the atomization core 3 and forms a liquid blocking portion 4221, the cross section of the liquid blocking portion 4221 is annular, and an end of the liquid blocking portion 4221 away from the bottom wall of the atomization groove 42 is higher than the bottom wall of the atomization groove 42, so as to prevent the aerosol-generating substrate or aerosol condensate in the liquid locking groove 421 or the atomization groove 42 from leaking through the first air supply hole 422. Specifically, the air outlet of the liquid blocking part 4221 can be arranged right opposite to the atomizing core 3, so that when the atomizing core 3 works, the direction of air flow entering from the first air supply hole 422 is right opposite to the direction of aerosol generated by atomization, and the aerosol can be directly taken away by the air flow; meanwhile, the probability of deformation caused by the contact of the aerosol with high temperature with the outlet end of the first air feed hole 422 can be reduced. In this case, the liquid blocking portion 4221 and the first air supply hole 422 are integrally formed, which facilitates manufacturing and prevents the condensate from flowing out from the gap therebetween. Of course, it is also possible that the bottom wall inner surface of the atomization groove 42 has an annular protrusion forming the liquid shield 4221, and the first air supply hole 422 penetrates the liquid shield 4221 to communicate with the atomization groove 42.

Specifically, referring to fig. 6, in order to prevent the liquid blocking portion 4221 from being melted by the heat radiated from the atomizing core 3, the liquid blocking portion 4221 is further provided with a plurality of heat dissipating ribs 420 on its outer circumferential surface. The plurality of heat dissipating ribs 420 may be uniformly distributed on the outer circumferential surface of the liquid blocking portion 4221 in a block shape, a strip shape, or a curved shape. Alternatively, each heat dissipation rib 420 extends to the bottom wall of the atomization groove 42 along the longitudinal direction of the liquid blocking portion 4221, and the plurality of heat dissipation ribs 420 are arranged at intervals along the circumferential direction of the liquid blocking portion 4221. Or the heat dissipation ribs 420 extend along the circumferential direction of the liquid blocking portion 4221, and the plurality of heat dissipation ribs 420 are arranged at intervals along the longitudinal direction of the liquid blocking portion 4221. Of course, the plurality of heat dissipation ribs 420 may also be disposed in any combination of the above distribution manners, which is not limited in this application.

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 air bleed 422 or other sealing structure within the atomization slot 42 to prevent the seeped aerosol-generating substrate and aerosol condensate from entering the battery receiving cavity and causing damage to the battery 6.

Specifically, the weep collection cavity 43 includes a first cavity wall 430, a second cavity wall, and a third cavity wall 45. As shown in fig. 4, the partition plate 41 doubles as a second chamber wall; the first cavity wall 430 is located between the atomizing core 3 and the second cavity wall and extends along the transverse direction of the fixing seat 4; the third chamber wall 45 is located between and connects the first chamber wall 430 and the second chamber wall, respectively, and serves as a side wall of the leakage collection chamber 43. In a specific embodiment, the air outlet of the first air inlet hole 40 is specifically located at the first cavity wall 430; when in suction, the electronic atomization device is generally vertically or obliquely arranged, and the air outlet of the first air inlet hole 40 is arranged at the position of the first cavity wall 430, so that condensate collected in the leaked liquid collection cavity 43 cannot flow out through the first air inlet hole 40 due to the action of gravity to cause the leakage problem; compared with the scheme that the first air inlet holes 40 are arranged on the bottom wall of the leaked liquid collecting cavity 43, namely the second cavity wall, due to the gravity action of condensate, the problem that the condensate in the leaked liquid collecting cavity 43 flows out of the first air inlet holes 40 to cause leakage easily occurs, and therefore the first air inlet holes 40 need to be extended into the leaked liquid collecting cavity 43 to avoid the leakage problem, but due to the arrangement, the space of the leaked liquid collecting cavity 43 can be occupied, and the liquid storage space is reduced; this scheme need not to extend first inlet port 40 to in the weeping collects chamber 43, also can prevent that the weeping from collecting the condensate of the interior storage of chamber 43, when the vertical placing of electron atomizing device, because of the action of gravity of condensate, the problem of following the outflow of first inlet port 40 takes place to effectively avoided first inlet port 40 to occupy the space in the weeping collects chamber 43, the problem that the stock solution space that leads to the weeping to collect chamber 43 diminishes takes place. In addition, compared with the scheme that the first air inlet holes 40 are arranged on the side wall of the leaked liquid collecting cavity 43, namely the scheme that the condensed liquid is discharged through the first air inlet holes 40 only after the condensed liquid occupies the whole leaked liquid collecting cavity 43, the scheme of the application can cause the problem that the condensed liquid is discharged through the first air inlet holes 40 if the first air inlet holes 40 are arranged on the side wall of the leaked liquid collecting cavity 43, and the problem that the condensed liquid is discharged through the first air inlet holes 40 can occur if the condensed liquid does not occupy the whole leaked liquid collecting cavity 43; therefore, the above-mentioned scheme of this application has further reduced the probability that the condensate goes out through first inlet port problem to a certain extent.

Specifically, as shown in fig. 2 and 4, the first intake holes 40 include a first intake section 423 and a second intake section 424 that communicate with each other. The first air inlet segment 423 extends to the side of the fixing seat 4 along the transverse direction of the fixing seat 4 (i.e. the direction perpendicular to the axial direction D of the fixing seat 4), and communicates with the outside atmosphere through the second air inlet hole 111, so that the structure can better prevent the condensate from leaking out through the first air inlet hole 40. The external atmosphere refers to the atmosphere outside the electronic atomization device. In an embodiment, as shown in fig. 2, the second air inlet hole 111 and the first air inlet section 423 are located at the same radial position of the atomizing assembly, and the second air inlet hole 111 and the port of the first air inlet section 423 facing away from the second air inlet section 424 are directly communicated; so as to shorten the distance from the air inlet of the first air inlet section 423 to the outside atmosphere, thereby reducing the probability of the problem of air inlet hole blockage.

The second air inlet section 424 extends along the longitudinal direction of the fixing base 4 (i.e. the axial direction D of the fixing base 4), and a first end of the second air inlet section 424 is communicated with the first air inlet section 423, and a second end of the second air inlet section 424 extends to the surface of the first cavity wall 430 of the leakage collecting cavity 43, which is close to the partition plate 41, so as to be communicated with the leakage collecting cavity 43. In the specific embodiment, the air flow enters the leakage liquid collecting cavity 43 through the second air inlet hole 111, the first air inlet section 423 and the second air inlet section 424 in sequence, and then enters the atomization cavity through the first air supply hole 422.

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. Further, as shown in fig. 2, in order to better seal the leakage collecting cavity 43, the electronic atomization 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 fixing 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 fixing seat 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 a fixing base according to 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 walls of the weep collection cavity 43 may comprise a bottom wall and/or a side wall. In another embodiment, referring to fig. 8, fig. 8 is a schematic structural view of a fixing base according to another embodiment of the present application; a weep absorbent member 432 may further be provided within the weep collection cavity 43 such that the aerosol-generating substrate or aerosol condensate entering the weep collection cavity 43 is absorbed by the weep absorbent member 432. The leakage adsorbing member 432 may be a cotton cloth, a sponge, or other liquid-absorbing member.

Referring to fig. 1 to 3, the inductor accommodating chamber 44 is also located between the partition plate 41 and the atomization slot 42; the inductor accommodating cavity 44 is used for accommodating the airflow inductor 5; compare in current scheme, airflow inductor 5 installs on fixing 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 electronic atomization device's miniaturization, 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 fixed seat 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 fixed seat 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. As shown in fig. 3, in one embodiment, the radial direction of the airflow sensor 5 is perpendicular to the radial direction of the fixing base 4.

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 held chamber 44 and atomizing core 3 all indicates along the axial direction D of fixing 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 fixing seat 4, and the two cavities have the same linear distance from the atomizing core 3, that is, the leaked liquid collecting cavity 43 and the inductor accommodating cavity 44 are arranged in parallel along the radial direction of the fixing seat 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 third chamber wall 45 of the leakage liquid collecting chamber 43 doubles as the bottom wall of the sensor accommodating chamber 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 third cavity wall 45 is further provided with a second air feeding hole 451, and the second air feeding hole 451 is communicated with the leakage collecting cavity 43 and the sensor accommodating cavity 44 and serves as an air pressure triggering channel for operating the air flow sensor 5 installed in the sensor accommodating cavity 44. The inductor accommodating cavity 44 is communicated with the first air supply hole 422 through the second air supply hole 451 and the leakage liquid collecting cavity 43, and further communicated with the atomization groove 42; compared with the scheme that the first air supply hole 422 is directly communicated with the atomization groove 42 and the inductor accommodating cavity 44, the air flow inductor 5 can be triggered to work when a user sucks the air flow inductor, and the aerosol is not easy to enter the inductor accommodating cavity 44 to generate aerosol condensate, so that the problem that the air flow inductor 5 is damaged by the aerosol condensate is solved. Preferably, the first air feed hole 422 extends along the axial direction D of the fixing base 4, and the second air feed hole 451 extends along the radial direction of the fixing base 4, so as to prevent the leaked aerosol-generating substrate or aerosol condensate from directly entering the inductor receiving cavity 44.

Preferably, the second air supply hole 451 is disposed adjacent to the first air supply hole 422; therefore, when an airflow passes through, the airflow sensor 5 can be triggered to work quickly; therefore, the sensitivity of the airflow sensor 5 can be improved. Further, along the radial direction of the fixing base 4, the linear distance between the air outlet of the second air inlet section 424 and the first air supply hole 422 may be equal to the linear distance between the air outlet of the second air supply hole 451 and the first air supply hole 422; wherein, the air outlet of the second air inlet section 424 refers to the downstream port of the second air inlet section 424 along the air flow direction; the air outlet of the second air feed hole 451 is directed to an end port of the second air feed hole 451 communicating with the leakage collecting chamber 43. When can guarantee like this that air current inductor 5 is triggered, outside air current can get into the atomizing intracavity as early as possible to take away the aerosol that atomizing intracavity atomizing formed and the heat that atomizing core 3 generated heat, avoid the high temperature and lead to the aerosol to generate the problem of matrix schizolysis and production formaldehyde.

Specifically, the distance between the second air supply hole 451 and the first cavity wall 430 is smaller than the distance between the second air supply hole 451 and the second cavity wall, and when the electronic atomization device is placed vertically, that is, along the axial direction D of the fixing base 4, the perpendicular distance between the second air supply hole 451 and the plane where the atomization core 3 is located is smaller than the perpendicular distance between the bottom wall of the leaked liquid collection cavity 43 (that is, the partition plate 41) and the plane where the atomization core 3 is located; thus, when the electronic atomization device is used, the problem that the aerosol-generating substrate or the aerosol condensate collected in the leakage collecting chamber 43 overflows into the inductor accommodating chamber 44 through the second air supply hole 451 can be effectively avoided, and the air flow inductor 5 can be prevented from being damaged. Further, the second air supply hole 451 may be disposed adjacent to the first air supply hole 422; therefore, when the first air supply hole 422 has air flow passing through, the air flow sensor 5 can be triggered to work quickly, and the sensitivity of the air flow sensor 5 can be effectively improved.

The second air supply hole 451 includes the first air supply section 451a and the second air supply section 451b arranged at a predetermined angle, so that the air passage of the second air supply hole 451 can be extended, and the aerosol dispersed into the second air supply hole 451 when the electronic atomizing device is operated can form condensate in the second air supply hole 451 as much as possible, thereby effectively reducing the damage rate of the airflow sensor 5 caused by the dispersion of the remaining aerosol into the sensor accommodating chamber 44.

As shown in fig. 10a and 10b, a first end of the first connecting lug 82 is connected to the sleeve portion 81, a fixing post 821 is disposed on a side surface of a second end of the first connecting lug 82 facing the fixing base 4, and the fixing post 821 is connected to the connecting hole 452 in an inserting manner, so as to fix the first connecting lug 82 to the fixing base 4.

The ventilation cavity 46 extends along the axial direction D of the fixing base 4, and the opening of the ventilation cavity 46 is located on the end surface of the fixing base 4 and faces the liquid storage cavity 121, so as to collect the aerosol-generating substrates leaking from the ventilation through hole 24, prevent the aerosol-generating substrates from blocking the ventilation through hole 24 to affect the ventilation effect, and avoid the problem that the aerosol-generating substrates further leak to the battery 6 or the airflow sensor 5 to damage the battery 6 or the airflow sensor 5. In the embodiment, the ventilation chamber 46 has a plate shape, and a length dimension of the ventilation chamber 46 along the axial direction D of the fixing base 4 is greater than a width dimension perpendicular to the axial direction D of the fixing base 4. Specifically, the section of the air exchange cavity 46 along the radial direction of the fixed seat 4 can be crescent, rectangular or elliptical; the ventilation chamber 46 has a relatively large reservoir of aerosol-generating substrate or condensate.

In a specific embodiment, as shown in fig. 6, the number of the air exchanging cavities 46 is specifically two, and the two air exchanging cavities 46 are oppositely arranged on two sides of the atomizing slot 42 along the radial direction of the fixing base 4; and a first ventilating hole 461 is formed on the side wall of each ventilating cavity 46 away from the atomizing slot 42, and the first ventilating hole 461 is communicated with the ventilating cavity 46 and the external atmosphere outside the electronic atomizing device. In one embodiment, when the electronic atomization device is vertically placed and the suction nozzle 120 faces upward, i.e. along the axial direction D of the fixing base 4, the first ventilation hole 461 is located at a position higher than the bottom wall of the ventilation cavity 46; this avoids the problem of loss of the battery 6 or the airflow sensor 5 due to leakage of aerosol-generating substrate or aerosol condensate stored in the ventilation chamber 46 through the first ventilation holes 461 when the electronic atomising device is vertically positioned.

Specifically, the fixing seat 4 and the first housing 11 or the second housing 12 are further matched to form a first ventilation channel and/or a second ventilation channel.

Of course, in other embodiments, the first scavenging groove 425 and/or the second scavenging groove 426 may be opened on the inner wall surface of the first housing 11, or the first scavenging groove 425 and/or the second scavenging groove 426 may be opened on the inner wall surface of the second housing 12; or, the ventilation grooves are formed in the positions, corresponding to the fixing seats 4, of the first shell 11 or the second shell 12, and the ventilation grooves in the first shell 11 or the second shell 12 are matched with the ventilation grooves in the outer side walls of the fixing seats 4 to form ventilation channels. This is not a limitation of the present application.

In a specific embodiment, see fig. 12 and 13; fig. 12 is an exploded view of an electronic atomizer device in accordance with another embodiment of the present application; FIG. 13 is a cross-sectional view taken along line C-C of the electronic atomizer shown in FIG. 12; a first end of the first scavenging groove 425 is communicated with the first scavenging hole 461, and a second end of the first scavenging groove 425 is communicated with the outside atmosphere through an air inlet on the shell 1; a first end of the second scavenging slot 426 is communicated with the first scavenging hole 461, and a second end of the second scavenging slot 426 is communicated with the outside atmosphere through an air inlet on the shell 1; so that the first transfer ports 461 can communicate with the external atmosphere through the first transfer grooves 425 and/or the second transfer grooves 426; thus, even if one of the first scavenging groove 425 and the second scavenging groove 426 is blocked, the first scavenging hole 461 can be scavenged through the other scavenging groove, and the probability of blockage of the scavenging channel of the reservoir 121 is reduced. Meanwhile, the second end of the first ventilation groove 425 is directly connected to the outside atmosphere, the second end of the second ventilation groove 426 is also directly communicated to the outside atmosphere, and compared with the scheme that the second end of the ventilation groove is communicated to the atomizing cavity, the scheme that the atomizing cavity is communicated with the outside atmosphere can avoid that aerosol in the atomizing cavity is diffused to the ventilation groove or the ventilation hole to cause the problem that the ventilation channel of the liquid storage cavity 121 is blocked.

The air inlet on the housing 1 may be the same through hole as the second air inlet hole 111, or a through hole different from the second air inlet hole 111. In an embodiment, as shown in fig. 12, a first ventilation inlet slot 112 is formed on the first housing 11 corresponding to the second end of the first ventilation slot 425 and the second end of the second ventilation slot 426, a second ventilation inlet slot 123 is formed on the second housing 12 corresponding to the first ventilation inlet slot 112, the first ventilation inlet slot 112 communicates with the outside atmosphere and the second ventilation inlet slot 123, and the second ventilation inlet slot 123 communicates with the first ventilation slot 425 or the second ventilation slot 426, so that the first ventilation slot 425 and the second ventilation slot 426 communicate with the outside atmosphere through the second ventilation inlet slot 123 and the first ventilation inlet slot 112 at corresponding positions. The first and second ventilation inlet slots 112, 123 together define an air inlet on the housing 1.

In another embodiment, as shown in fig. 3, 5 and 7, the fixing base 4 further includes a second venting hole 427 and a third venting hole 428, a first end of the second venting hole 427 is communicated with a second end of the first venting groove 425, and a second end of the second venting hole 427 is communicated with the atomization chamber; the first end of the third scavenging hole 428 is communicated with the second end of the second scavenging slot 426, and the second end of the third scavenging hole 428 is communicated with the atomizing chamber. That is, the second ventilation groove 426 of the present embodiment communicates with the outside atmosphere through the atomization chamber. Thus, in the process of atomizing the aerosol-generating substrate by the atomizing core 3, even if part of the aerosol spreads to the first ventilation groove 425 or the second ventilation groove 426 to form aerosol condensate, since the air pressure in the atomizing chamber is gradually increased and negative pressure is formed in the liquid storage chamber 121 along with the continuous outflow of the aerosol-generating substrate, the aerosol condensate in the first ventilation groove 425 or the second ventilation groove 426 gradually flows into the ventilation chamber 46 under the action of the pressure difference, so that the aerosol condensate can be effectively prevented from blocking the first ventilation groove 425 or the second ventilation groove 426 or preventing the ventilation speed from being increased to influence the ventilation effect. Specifically, an air-exchanging inner groove (not shown) is formed between the side wall of the atomizing support 2 and the inner wall of the atomizing groove 42, and the second air-exchanging holes 427 and the third air-exchanging holes 428 are respectively communicated with the atomizing chamber through the air-exchanging inner groove.

This avoids interference of aerosol condensate in the first deaeration tank 425 and the second deaeration tank 426.

In particular, as shown in fig. 14, the height of the second ventilation holes 427 and/or the third ventilation holes 428 in the axial direction D of the fixed base 4 is higher than the bottom wall of the nebulization chamber, i.e. higher than the bottom wall of the nebulization channel 42, so that the aerosol-generating substrate or aerosol condensate in the nebulization chamber can be prevented from flowing into the second ventilation holes 427 and/or the third ventilation holes 428. Further, the height of the second ventilation holes 427 in the axial direction D of the fixing seat 4 is the same as the height of the third ventilation holes 428 in the axial direction D of the fixing seat 4; that is, the positions of the first and second venting holes 461, 427 are located at the same radial position of the fixing seat 4; and the second ventilation holes 427 are opposite to the third ventilation holes 428 in the radial direction of the fixed base 4.

In this embodiment, as shown in fig. 14, the orthographic projection of the atomizing core 3 on the wall of the atomizing slot 42 facing the venting chamber 46, i.e., the orthographic projection of the atomizing core 3 on thebase:Sub>A-base:Sub>A plane, is at least partially located between the second venting hole 427 and the third venting hole 428. This enables the ventilation to be driven quickly in accordance with the pressure changes at which the atomizing core 3 operates. Specifically, the second ventilation holes 427 and the third ventilation holes 428 are located at the same radial positions as the side surface of the atomizing core 3 facing the bottom wall of the atomizing groove 42; that is, in the axial direction D of the fixed base 4, the second ventilation holes 427 and the third ventilation holes 428 are located at the same height as the height of the side surface of the atomizing core 3 facing the bottom wall of the atomizing groove 42. Therefore, the air exchange can be further driven quickly according to the pressure change of the atomizing core 3 during working.

It will be appreciated that when a negative pressure is formed in the reservoir 121, the elastic sealing cap 93 is pushed up toward the reservoir 121 by a pressure difference to communicate and ventilate the ventilation through-hole 24 with the reservoir 121.

Specifically, the sealing cover 93 has a first opening 933 at a position corresponding to the liquid inlet hole 21 of the atomizing support 2, so as to ensure that the aerosol-generating substrate in the liquid storage chamber 121 smoothly enters the liquid inlet hole 21. Sealing cover 93 corresponds to second air outlet channel 22 of atomizing support 2 and has second opening 934 to ensure that first air outlet channel 122 can pass through second opening 934 and communicate with second air outlet channel 22.

As shown in fig. 1 to 3, the sealing seat 94 is disposed in the fixing groove 25 and wraps the circumferential side of the atomizing core 3, and is located between the atomizing core 3 and the liquid inlet hole 21, so as to prevent the aerosol-generating substrate flowing out from the liquid inlet hole 21 from directly flowing out to the atomizing chamber from the gap between the atomizing core 3 and the atomizing support 2. Specifically, as shown in fig. 1, the sealing seat 94 is provided with a liquid guiding hole 941 at a position corresponding to the liquid inlet hole 21, so as to guide the aerosol-generating substrate flowing out from the liquid inlet hole 21 to the surface of the atomizing core 3. In a specific embodiment, as shown in fig. 1 in combination with fig. 16, fig. 16 is a schematic view of the sealing seat abutting against the atomizing mount; the end surface of the sealing seat 94 facing away from the battery accommodating cavity is provided with a plurality of elastic support columns 942 arranged at intervals, and the elastic support columns 942 are elastically abutted with the groove walls of the fixing groove 25. By arranging the elastic support columns 942, when the atomizing core 3 is installed in the atomizing support 2, the elastic support columns 942 can relatively flatly abut against the groove walls of the fixing groove 25, so that the elastic deformation of the region of the seal seat 94 located in the elastic support columns 942 is more uniform, and the atomizing core 3 in the seal seat 94 is prevented from cracking due to uneven stress.

The third sealing ring 7c is embedded in the sealing groove 429c on the periphery of the fixing base 4 and is located between the liquid storage cavity 121 and the leakage collecting cavity 43 along the axial direction D of the fixing base 4, so as to prevent the aerosol-generating substrate and/or the aerosol condensate in the liquid storage cavity 121 from leaking into the battery accommodating cavity or the inductor accommodating cavity 44 from a gap between the fixing base 4 and the first housing 11.
