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. The leakage collecting cavity 43 is used for collecting the aerosol-generating substrate and the aerosol condensate leaking out of the first vent hole 422 in the atomization tank 42, so as to prevent the leaked aerosol-generating substrate and the leaked aerosol condensate from entering the battery accommodating cavity and damaging the battery 6.

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 end of the second air inlet hole 4331 is 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 cavity 43 through the first air inlet hole 111 and the second air inlet hole 4331 in sequence, and then enters the atomization cavity through the first air outlet hole 422.

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 atomization 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 snapped into the seal groove 429b for fixation.

Wherein leakage of aerosol-generating substrate or aerosol condensate from the weep collection cavity 43 is prevented 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 wall 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 an atomizing base according to another embodiment of the present application; an adsorbent 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 adsorbent member 432. Wherein the absorption member 432 may be a cotton cloth, a 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 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 atomizing base 4 are inclined 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 straight distance between the leaked liquid collecting cavity 43 and the atomizing core 3 is not less than the straight distance between the inductor accommodating cavity 44 and the atomizing core 3; this enables the aerosol condensate or aerosol-generating substrate to flow under its own weight towards the leakage-collecting chamber 43 when present in the sensor-receiving cavity 44, reducing the build-up of aerosol condensate or aerosol-generating substrate in the sensor-receiving cavity 44, thereby acting to protect the airflow sensor 5 disposed within the sensor-receiving cavity 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 in 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 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 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; this baffle 45 will atomize the space between the diapire of groove 42 and baffle 41 and divide into two parts, and the first part is as leaking liquid collection chamber 43, and the second part is used for setting up inductor and holds chamber 44, and this baffle 45 doubles the lateral wall of leaking liquid collection chamber 43 and the diapire of inductor and holding 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 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 is used as an air pressure triggering channel for the operation of the air flow sensor 5 installed in the sensor accommodating cavity 44. Wherein, the inductor holds chamber 44 and collects chamber 43 and first exhaust hole 422 intercommunication through second exhaust hole 451 and weeping, and then intercommunication atomizing groove 42, compare in the scheme that first exhaust hole 422 direct intercommunication atomizing groove 42 and inductor hold chamber 44, not only can trigger the work of air current inductor 5 when the user sucks, and can prevent to hold chamber 44 through the direct entering inductor of aerosol generation matrix or aerosol condensate of first exhaust hole 422 seepage, lead to the problem of air current inductor 5 damage to take place. Preferably, the first venting holes 422 extend in the axial direction D of the nebulizing base 4 and the second venting holes 451 extend in the radial direction of the nebulizing base 4, so as to avoid the direct ingress of the leaking aerosol-generating substrate or aerosol condensate into the sensor housing chamber 44.

Specifically, when the electronic atomization device is placed vertically, that is, along the axial direction D of the atomization base 4, the vertical distance between the second exhaust hole 451 and the plane where the atomization core 3 is located is smaller than the vertical distance between the bottom wall of the leaked liquid collection cavity 43 (i.e., 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 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 exhaust hole 451 may be disposed adjacent to the first exhaust hole 422; therefore, when the first exhaust hole 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 vent hole and a connecting hole provided in an embodiment of the present application; the second exhaust hole 451 specifically includes a first exhaust section 451a and a second exhaust section 451b that are communicated with each other. The first exhaust section 451a is communicated with the leakage liquid collecting cavity 43, and the second exhaust section 451b is communicated with the sensor accommodating cavity 44; and the first exhaust section 451a forms an angle alpha with the second exhaust section 451b that is greater than 0 deg. and less than 180 deg.. The second vent hole 451 comprises a first vent section 451a and a second vent section 451b which are arranged at a certain included angle, so that the vent path of the second vent hole 451 can be extended, aerosol diffusing into the second vent hole 451 when the electronic atomization device works, and condensate is formed in the second vent hole 451 as much as possible, thereby effectively reducing the damage rate of the air flow sensor 5 caused by the fact that the remaining aerosol diffuses into the sensor accommodating cavity 44. In one embodiment, the second exhaust section 451b is perpendicular to the first exhaust section 451 a; and as shown in fig. 5 and 9, the end of the second exhaust section 451b facing away from the inductor-receiving cavity 44 is further extended with a connection hole 452.

The ventilation chamber 46 extends along the axial direction D of the atomizing base 4, and the orifice of the ventilation chamber 46 is located on the end surface of the atomizing base 4 and faces the liquid storage chamber 121, so as to collect 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 battery 6 or the airflow sensor 5 is damaged due to the aerosol-generating substrates further leaking to the battery 6 or the airflow sensor 5. In the specific embodiment, the section of the ventilation cavity 46 along the axial direction of the atomizing base 4 is plate-shaped, and the length dimension of the ventilation cavity 46 along the axial direction D of the atomizing base 4 is greater than the width dimension perpendicular to the axial direction D of the atomizing base 4. Specifically, the section of the ventilation cavity 46 along the radial direction of the atomizing base 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 ventilating cavities 46 is specifically two, and the two ventilating cavities 46 are oppositely arranged at two sides of the atomizing slot 42 along the radial direction of the atomizing 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 outside atmosphere. It is understood that the outside atmosphere refers to the atmosphere outside the electronic atomization device. In one embodiment, when the electronic atomizer is placed vertically with the suction nozzle 120 facing upward, i.e. along the axial direction D of the atomizing base 4, the first venting holes 461 are located at a height higher than the bottom wall of the venting chamber 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 atomizing base 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. As shown in fig. 4 and 5, in a specific embodiment, a first ventilation groove 425 and a second ventilation groove 426 are formed on an outer side wall of the atomizing base 4, the first ventilation groove 425 fits and cooperates with an inner wall surface of the first housing 11 or the second housing 12 to form a first ventilation channel, and the second ventilation groove 426 fits and cooperates with an inner wall surface of the first housing 11 or the second housing 12 to form a second ventilation channel; the following examples are given as examples. 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 positions of the first shell 11 or the second shell 12 corresponding to the atomizing base 4 are both provided with air exchanging grooves, and the air exchanging grooves on the first shell 11 or the second shell 12 are matched with the air exchanging grooves on the outer side wall of the atomizing base 4 to form an air exchanging channel. 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 liquid storage cavity 121 is reduced. Meanwhile, the second end of the first ventilation groove 425 is directly connected to the outside atmosphere, and the second end of the second ventilation groove 426 is also directly communicated to the outside atmosphere, so that compared with the scheme that the second end of the ventilation groove is communicated to the atomization cavity, the atomization cavity is communicated with the outside atmosphere, the aerosol in the atomization cavity can be prevented from being diffused to the ventilation groove or the ventilation hole, and the problem that the ventilation channel of the liquid storage cavity 121 is blocked is caused.

The air inlet on the housing 1 may be the same through hole as the first air inlet hole 111, or a through hole different from the first 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 and 123 together define an air inlet on the housing 1.

In another embodiment, as shown in fig. 3, 5 and 7, the atomizing base 4 further comprises a second ventilating hole 427 and a third ventilating hole 428, a first end of the second ventilating hole 427 is communicated with a second end of the first ventilating groove 425, and a second end of the second ventilating hole 427 is communicated with the atomizing chamber; the first end of the third scavenging hole 428 is communicated with the second end of the second scavenging groove 426, and the second end of the third scavenging hole 428 is communicated with the atomizing chamber. That is, the second scavenging groove 426 of the present embodiment communicates with the outside atmosphere through the atomizing chamber. Thus, in the process of atomizing the aerosol-generating substrate by the atomizing core 3, even if part of the aerosol diffuses to the first air exchange groove 425 or the second air exchange 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 continuous outflow of the aerosol-generating substrate, the aerosol condensate in the first air exchange groove 425 or the second air exchange groove 426 gradually flows into the air exchange chamber 46 under the action of the pressure difference, so that the phenomenon that the aerosol condensate blocks the first air exchange groove 425 or the second air exchange groove 426 or the air exchange effect is influenced by the air exchange speed is prevented. Specifically, an inner ventilation 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 ventilation holes 427 and the third ventilation holes 428 are respectively communicated with the atomizing chamber through the inner ventilation 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 second ventilation holes 427 and/or the third ventilation holes 428 are located at a higher level along the axial direction D of the atomizing base 4 than the bottom wall of the atomizing chamber, i.e. the bottom wall of the atomizing slot 42, so that the aerosol-generating substrate or the aerosol condensate in the atomizing chamber can be prevented from flowing into the second ventilation holes 427 and/or the third ventilation holes 428. Further, the second ventilation holes 427 are located at the same height in the axial direction D of the atomizing base 4 as the third ventilation holes 428 are located in the axial direction D of the atomizing base 4; that is, the positions of the first and second scavenging holes 461, 427 are located at the same radial position of the atomizing base 4; and the second scavenging holes 427 are arranged opposite to the third scavenging holes 428 in the radial direction of the atomizing 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 is operating. Specifically, the second ventilation holes 427 and the third ventilation holes 428 are located at the same radial positions as the side surfaces of the atomizing core 3 facing the bottom wall of the atomizing groove 42; i.e., in the axial direction D of the atomizing base 4, the second ventilation holes 427 and the third ventilation holes 428 are located at the same height as the atomizing core 3 is located at the position of the side surface facing the bottom wall of the atomizing groove 42. So that the air exchange can be further quickly driven according to the pressure change of the atomizing core 3 during working.

In an embodiment, referring to fig. 1 and 2, the electronic atomization device further includes an electrode 91, an electronic lead 92, a sealing cover 93, a sealing seat 94, and a third sealing ring 7c. Wherein, the electrode 91 is fixed in the atomization groove 42 of the atomization base 4, and is abutted against the atomization core 3, and is connected with the battery 6 through the electronic lead 92 to supply power to the atomization core 3.

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. It is understood that, in another embodiment, when the ventilation through hole 24 is provided to be small, the sealing cover 93 may not be provided, thereby achieving the purpose of structural simplification.

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.

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 sealing seat 94 located in the elastic support columns 942 is more uniform, and the atomizing core 3 in the sealing 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 atomizing base 4 and is located between the liquid storage cavity 121 and the leakage collecting cavity 43 along the axial direction D of the atomizing base 4, so as to prevent the aerosol generating substrate and/or the aerosol condensate in the liquid storage cavity 121 from leaking to the battery accommodating cavity or the inductor accommodating cavity 44 from a gap between the atomizing base 4 and the first housing 11.
