That is, the inlet air passage is located at the bottom side of the atomization chamber 11a, and the outlet air passage 12a is located at the top side of the atomization chamber 11a. Optionally, one end of the air outlet channel 12a communicates with the open end 11d of the air guide channel 11c shown in some of the embodiments described above to realize the air suction process. It will be understood that the top and bottom ends are described with reference to the orientation of the drawings, and in particular, with reference to the direction of flow of the air stream during suction, the top end is referred to as upstream and the bottom end is referred to as downstream.

In an embodiment, referring to fig. 2 and 3, the atomizing base 11 includes an atomizing base 112 and an atomizing top base 111, an atomizing cavity 11a is defined between the atomizing base 112 and the atomizing top base 111, and the vent 11f and the ventilation through groove 11b penetrate through a sidewall of the atomizing top base 111 and communicate with the atomizing cavity 11a. The atomizing top mount 111 is also formed with an air guide passage 11c and a lower liquid passage 111d. The atomizing core 13 is disposed in the atomizing chamber 11a, and the lower liquid passage 111d guides the aerosol-generating substrate to the atomizing surface of the atomizing core 13 located in the atomizing chamber 11a. When a heating element (not shown) in the atomizer 10 is energized to convert electric energy into heat energy, the liquid absorbed by the atomizing core 13 is atomized to form aerosol and discharged into the atomizing chamber 11a, and when an air suction action of air flow is generated in the air outlet channel 12a, the aerosol in the atomizing chamber 11a enters the air outlet channel 12a to be used by a user.

In one embodiment, referring to fig. 1 and 2, the open end 11d and the ventilation outlet 10c are formed at the top end of the atomizing top seat 111, and the top end of the atomizing top seat 111 and the housing 12 define a liquid storage chamber 10a. In other embodiments, the ventilation outlet 10c may be formed on the inner wall of the lower liquid passage 111d.

In one embodiment, the liquid inlet of the lower liquid channel 111d is also formed at the top end of the atomizing top seat 111. Illustratively, the liquid inlets of the 2 lower liquid channels 111d are symmetrically distributed along the central axis of the gas outlet channel 12a.

In one embodiment, referring to fig. 3, the atomizing top seat 111 is formed with a ventilation slot 111a communicated with the ventilation outlet 10c, one end of the ventilation slot 111a far away from the ventilation outlet 10c is communicated to the ventilation through slot 11b, and the external air flow entering through the ventilation through slot 11b can be transmitted to the ventilation outlet 10c through the ventilation slot 111a and enter the liquid storage cavity 10a, so as to realize ventilation in the liquid storage cavity 10a.

In one embodiment, referring to fig. 3, the atomizing base 11 has a plurality of air-exchanging sub-grooves 111b formed on the outer circumferential wall thereof, and the air-exchanging sub-grooves 111b are sequentially communicated to form the curved air-exchanging groove 111a. By providing a plurality of ventilation sub-grooves 111b which are sequentially communicated, a curved ventilation channel 10b is formed, for example, a labyrinth-like ventilation channel 10b is formed, for preventing the aerosol-generating substrate in the liquid storage chamber 10a from leaking after entering the ventilation channel 10b through the ventilation outlet 10 c. For example, when the air pressure in the reservoir chamber 10a becomes low (e.g., when the electronic atomizer is transported by airplane), the volume of the air bubbles in the reservoir chamber 10a becomes large, and the aerosol-generating substrate overflowing through the ventilation outlet 10c is accommodated in the plurality of ventilation slots 111b, which are connected in series, thereby improving leakage. When the air pressure in the liquid storage chamber 10a is recovered to normal, the aerosol-generating substrate stored in the air exchange tank 111b may flow back into the liquid storage chamber 10a through the air exchange outlet 10c, thereby improving the negative pressure leakage.

The scavenging inlet 10d communicates with the first scavenging sub-slot 111b in the flow direction of the air current, and the scavenging outlet 10c communicates with the last scavenging sub-slot 111b in the flow direction of the air current. Thus, the external air flow flows from the ventilation inlet 10d to the first ventilation sub-slot 111b along the air flow direction, flows to the ventilation outlet 10c through the last ventilation sub-slot 111b along the air flow direction, and enters the liquid storage cavity 10a through the ventilation outlet 10c for ventilation.

Specifically, the outer peripheral wall of the atomizing top 111 is formed with a plurality of ventilator grooves 111b, and the ventilator grooves 111b are sequentially communicated with each other to form the curved ventilator groove 111a.

In one embodiment, referring to fig. 1 and 5, the atomizer 10 includes a sealing member 14, and the sealing member 14 is sleeved on the atomizing base 11.

Specifically, the sealing member 14 is sleeved on the atomizing top seat 111; some installation gaps can exist between the atomizing top seat 111 and the housing 12, and the sealing member 14 is sleeved on the periphery of the atomizing top seat 111 to seal the installation gap between the atomizing top seat 111 and the housing 12, so that aerosol generating substrates in the liquid storage cavity 10a can be prevented from flowing out through the installation gap between the atomizing top seat 111 and the housing 12, and liquid leakage can be prevented. Of course, the sealing member 14 can also be sleeved on the atomizing base 112 and the atomizing top seat 111 at the same time.

A ventilation channel 10b is defined between the sealing element 14 and the wall of the ventilation groove 111a, wherein a ventilation hole is further formed on the sealing element 14, and the ventilation hole is communicated between the liquid storage cavity 10a and the ventilation outlet 10 c. Thus, the external air flow flows to the ventilation outlet 10c through the ventilation channel 10b and then enters the liquid storage cavity 10a through the ventilation hole, so as to realize ventilation of the liquid storage cavity 10a.

The sealing member 14 is further provided with a liquid discharging hole, and the liquid discharging hole is communicated between the liquid storage cavity 10a and the liquid discharging channel 111d. In this manner, aerosol-generating substrate in the reservoir chamber 10a can enter the weep channel 111d through the weep hole.

The drain hole and the ventilation hole may be provided separately or may be through holes communicating with each other, that is, the through holes may be used as the drain hole or the ventilation hole.

In one embodiment, the atomizing top base 111 has a mold outlet 11h penetrating through a sidewall of the atomizing top base 111, and the mold outlet 11h is communicated with the air guide channel 11c. The mold outlet 11h is provided to facilitate mold stripping of the atomizing top 111.

In one embodiment, referring to fig. 3, a liquid storage tank 11g is formed on a side wall of the atomizing base 11, and the liquid storage tank 11g is communicated with the ventilation through groove 11 b. Specifically, the side wall of the atomizing top 111 is formed with a reservoir 11g. Of course, the side walls of the atomizing top 111 and the atomizing base 112 may be formed with reservoirs 11g.

When the aerosol in the ventilation through groove 11b generates excessive substrates or condensate, the aerosol generates substrates or condensate and can enter the liquid storage tank 11g through the ventilation through groove 11b, namely, the liquid storage tank 11g can play a role in liquid storage, so that the risk of liquid leakage caused by the fact that the excessive aerosol is accumulated in the ventilation through groove 11b can be avoided to a certain extent.

In one embodiment, the number of the liquid storage tanks 11g is multiple, and the multiple liquid storage tanks 11g are arranged at intervals along the height direction of the atomizing base 11. Illustratively, the number of the liquid storage tanks 11g corresponding to each ventilation through slot 11b is 2, and the 2 liquid storage tanks 11g are uniformly arranged at intervals along the height direction of the atomizing base 11. Therefore, the plurality of liquid storage tanks 11g not only improve the capacity of storing aerosol generating substrates or condensate, but also avoid the situation that the liquid cannot be stored due to the blockage of any one liquid storage tank 11g.

In the embodiments of the present application, the plurality of fingers includes two or more fingers. In an embodiment, referring to fig. 1, fig. 2 and fig. 6, the atomizing base 11 is provided with a surrounding edge 111h located in the atomizing cavity 11a, the surrounding edge 111h surrounds to form a containing cavity 111e, the atomizer 10 includes an atomizing core 13 disposed in the containing cavity 111e, and the aerosol-generating substrate in the liquid storage cavity 10a is guided to the atomizing core 13 through the liquid discharge channel 111d. The power supply assembly 30 is electrically connected to the atomizing core 13 for supplying power to the atomizing core 13. A liquid storage cavity 10a for storing the aerosol-generating substrate is defined between the top wall of the atomizing base 11 and the housing 12, the atomizing base 11 is formed with an atomizing cavity 11a and at least one lower liquid channel 111d, and the lower liquid channel 111d is communicated between the liquid storage cavity 10a and the atomizing cavity 11a. That is, the aerosol-generating substrate stored in the liquid storage chamber 10a is guided to the atomizing core 13 through the lower liquid passage 111d for thermal atomization.

In other embodiments, the surrounding edge 111h and the sidewall of the atomizing base 11 together surround to form a containing cavity 111e.

In an embodiment, referring to fig. 4, 6 and 7, the atomizing base 11 is provided with a connecting rib 111f, and the connecting rib 111f is disposed between the surrounding edge 111h and the sidewall of the atomizing chamber 11a.

That is, the connecting rib 111f is provided between the peripheral edge 111h and the side wall of the atomizing chamber 11a, and plays a role of improving the structural strength of the atomizing top 111.

The ventilation channel 11b is spaced apart from the air guide channel 11c by the connecting rib 111f, that is, at least one connecting rib 111f is provided between the ventilation channel 11b and the ventilation opening 11f, so that the aerosol-generating substrate or the condensate in the ventilation channel 10b can be prevented from entering the air guide channel 11c. To accommodate the new national standard tobacco flavor requirements, the interstices of the atomizing core 13 are enlarged and the aerosol-generating substrate within the atomizing core 13 may seep out, so that there may be aerosol-generating substrate between the atomizing core 13 and the inner wall of the receiving cavity 111e. Since the clearance between the atomizing core 13 and the inner wall of the accommodating chamber 111e is small, the clearance between the atomizing core 13 and the inner wall of the accommodating chamber 111e generates capillary action. In the related art, along the direction that the aerosol-generating substrate flows from the liquid storage cavity 10a to the accommodating cavity 111e, the opening end surface of the accommodating cavity 111e is flush with the end surface of the connecting rib 111f, so that the aerosol-generating substrate in the gap between the atomizing core 13 and the inner wall of the accommodating cavity 111e can climb along the end surface of the connecting rib 111f, and the aerosol-generating substrate in the gap between the atomizing core 13 and the inner wall of the accommodating cavity 111e flows out of the atomizing base 11, thereby causing liquid leakage.

In an embodiment, referring to fig. 6 and 7, a height difference exists between at least an end surface of a connection portion of the connecting rib 111f and the surrounding edge 111h and an end surface of the surrounding edge 111h, for example, a distance between at least an end surface of a connection portion of the connecting rib 111f and the surrounding edge 111h and a top wall of the atomizing base 11 is smaller than a distance between an end surface of the surrounding edge 111h and a top wall of the atomizing base 11, that is, the end surface of the connecting rib 111f sinks, and an end surface of a connection portion of the connecting rib 111f and a side wall of the accommodating cavity 111e is lower than an end surface of a side wall of the accommodating cavity 111e, that is, by setting the end surface of the connecting rib 111f to be lower than an opening end surface of the accommodating cavity 111e, the aerosol generating substrate in a gap between the atomizing core 13 and an inner wall of the accommodating cavity 111e can be prevented from climbing along the end surface of the connecting rib 111f to some extent, that the aerosol generating substrate in the gap between the atomizing core 13 and the inner wall of the accommodating cavity 111e can be prevented from flowing out of the atomizing base 11 to some extent.

In other embodiments, the height difference between the end surface of the connection portion of the connecting rib 111f and at least the peripheral edge 111h and the end surface of the peripheral edge 111h may be obtained by heightening the connecting rib 111f, so that the air guide channel 11c and the ventilation through groove 11b may be better blocked, and the aerosol-generating substrate in the gap between the atomizing core 13 and the inner wall of the accommodating cavity 111e may be prevented from climbing along the end surface of the connecting rib 111f, that is, the aerosol-generating substrate in the gap between the atomizing core 13 and the inner wall of the accommodating cavity 111e may be prevented from flowing out of the atomizing base 11 to some extent.

It should be noted that, the distance between the end face of the connection portion of the connecting rib 111f and at least the side wall of the accommodating cavity 111e and the top wall of the atomizing base 11 is smaller than the distance between the end face of the side wall of the accommodating cavity 111e and the top wall of the atomizing base 11, that is, the distance between the end face of the connection portion of the connecting rib 111f and the side wall of the accommodating cavity 111e and the top wall of the atomizing base 11 may be smaller than the distance between the end face of the side wall of the accommodating cavity 111e and the top wall of the atomizing base 111, or the distance between the end face of the connecting rib 111f and the top wall of the atomizing base 11 may be smaller than the distance between the end face of the side wall of the accommodating cavity 111e and the top wall of the atomizing base 111.

The surrounding edge 111h and the side wall of the atomizing seat 11 are both arranged at intervals, and as shown in fig. 7, the surrounding edge 111h and the side wall of the atomizing seat 11 are both arranged at intervals. Thus, the aerosol-generating substrate in the gap between the atomizing core 13 and the inner wall of the accommodating cavity 111e can be prevented from climbing to the end face of the side wall of the accommodating cavity 111e along the end face of the side wall of the accommodating cavity 111e to some extent, that is, the aerosol-generating substrate in the gap between the atomizing core 13 and the inner wall of the accommodating cavity 111e can be prevented from flowing out of the atomizing base 11 to some extent.

The lateral wall that holds chamber 111e is connected through splice bar 111f with the lateral wall of atomizing seat 11 between, and the splice bar 111f terminal surface sinks, and the distance of the terminal surface of splice bar 111f and the roof of atomizing seat 11 is less than the distance of the terminal surface that holds chamber 111e lateral wall and the roof of atomizing seat 11, can prevent to a certain extent that atomizing core 13 and the aerosol that holds in the clearance between the chamber 111e inner wall from producing the matrix and climbing along the terminal surface of splice bar 111 f.
