In other embodiments, the bottom cover 15 may also include support posts that abut the bottom wall of the support 125 to support the heat generating component 12.

Referring to fig. 3, 7 and 10, a first opening 1252 is provided in the bottom wall of the support 125; the annular sidewall of the mounting groove 1230 is provided with a second opening 1235 and a third opening 1236 on opposite sides. Wherein the first opening 1252 communicates with the second opening 1235, and the air inlet chamber 103 communicates with the atomizing chamber 101 through the first opening 1252 and the second opening 1235; the third opening 1236 communicates the nebulization chamber 101 with the outlet aperture 1311, i.e. the aerosol in the nebulization chamber 101 enters the outlet channel 102 through the third opening 1236, the outlet aperture 1311. That is, the external air enters the atomizing chamber 101 through the air inlet chamber 103, the first opening 1252 and the second opening 1235, and carries the aerosol in the atomizing chamber 101 to enter the air outlet channel 102 through the third opening 1236 and the air outlet hole 1311, and is finally sucked by the user. In one embodiment, the first opening 1252, the second opening 1235, the atomizing chamber 101, the third opening 1236, and the gas outlet 1311 are all the same in cross section perpendicular to the axial direction of the atomizer 1, for example, are all rectangular.

Referring to fig. 3, the first opening 1252, the second opening 1235, the atomizing chamber 101, the third opening 1236, the air outlet 1311 and the air outlet channel 102 are in linear communication, and there is no bend and no shielding between the air outlet channel 102 and the atomizing chamber 101, so that contact between aerosol and a wall surface is reduced, and thus formation of condensate is reduced, and meanwhile, the temperature of the aerosol reaching the mouth of a user is improved, which is beneficial to keeping a better taste to improve the use experience of the user. It can be appreciated that there is no bend or no shielding between the air outlet channel 102 and the atomizing chamber 101, which is beneficial to discharging the aerosol in the atomizing chamber 101, thereby reducing the loss of the aerosol.

The atomizing cavity 101 is communicated with the air inlet cavity 103 in a straight line, so that no turning exists between the air inlet cavity 103 and the atomizing cavity 101, and external air is blown through the atomizing surface of the heating body 121, so that the mixing uniformity degree of aerosol and air is improved, the air flow is smooth and uniform, and good taste is kept.

It will be appreciated that as the aerosol-generating substrate within the reservoir 110 is consumed, the negative pressure within the reservoir 110 increases gradually, and in order to prevent the aerosol-generating substrate within the reservoir 110 from being unable to be supplied to the heating element 12 due to too much negative pressure within the reservoir 110, a portion of air is required to enter the reservoir 110 to ventilate it, and based on this, the application also provides a ventilation mode.

Referring to fig. 4, a ventilation pinhole 1315 is provided on the annular side wall of the housing 131, for example, the ventilation pinhole 1315 is located on the side of the heat generating component 12 facing away from the liquid outlet opening 1312. The ventilation needle hole 1315 communicates the internal space of the housing portion 131 with the liquid storage chamber 110, that is, the ventilation needle hole 1315 communicates the housing chamber 1310 with the liquid storage chamber 110. The outer surface of the heating element 12 and the inner surface of the accommodating portion 131 cooperate to form a communication channel 104, a first end of the communication channel 104 is communicated with the ventilation needle hole 1315, and a second end of the communication channel 104 is communicated with the outside air. That is, ventilation of the reservoir 110 is achieved through the communication passage 104 and the ventilation needle hole 1315.

The ventilation needle hole 1315 is not higher than the bottom surface of the liquid storage chamber 110, i.e., the top surface of the sealing member 14. When the aerosol-generating substrate in the reservoir 110 is consumed, there is also aerosol-generating substrate in the ventilation pinhole 1315 to achieve a threshold of communication for maintaining ventilation by surface tension of the aerosol-generating substrate in the ventilation pinhole 1315. When no aerosol generating substrate is in the ventilation needle hole 1315, the liquid storage cavity 110 is communicated with the outside air through the ventilation needle hole 1315 and the communication channel 104, so that the liquid leakage is caused by insufficient negative pressure in the liquid storage cavity 110.

Further, a first groove 1316 is provided on the outer surface of the annular sidewall of the housing portion 131 near the bottom surface of the liquid storage chamber 110, and a ventilation pinhole 1315 is provided on the bottom wall of the first groove 1316. The lowest point C of the first groove 1316 is lower than the bottom surface of the reservoir 110 such that less aerosol-generating substrate within the reservoir 110 is still able to flow into the first groove 1316; the highest point D of the first groove 1316 is higher than the bottom surface of the reservoir 110 so that aerosol-generating substrate within the reservoir 110 can flow into the first groove 1316. Optionally, the bottom surface of the liquid storage cavity 110 is an inclined surface, and the bottom surface of the liquid storage cavity 110 near the first groove 1316 is lower than the bottom surface of the liquid storage cavity 110 far from the first groove 1316, so as to facilitate the aerosol-generating substrate in the liquid storage cavity 110 to flow into the first groove 1316 as much as possible when the aerosol-generating substrate is less. By providing the first recess 1316, there is always aerosol generating substrate in the ventilation needle hole 1315.

In the present embodiment, the outer surface of the heat generating component 12 is provided with a second groove (not shown), and the second groove cooperates with the inner surface of the accommodating portion 131 to form the communication channel 104; that is, the inner surface of the side wall of the housing portion 131 having the ventilation pinhole 1315 is formed into the communication passage 104 in cooperation with the second groove. Specifically, the side wall of the supporting member 125 of the heat generating component 12 far from the pressing member 124 is provided with a second groove, that is, the surface of the side wall of the supporting member 125 far from the pressing member 124 cooperates with the inner surface of the receiving portion 131 to form the communication channel 104. In other embodiments, a second groove may be provided on the inner surface of the accommodating portion 131 to form the communication channel 104 in cooperation with the outer surface of the supporting member 125 of the heat generating component 12.

The communication passage 104 is provided in parallel with the atomizing chamber 101, and the communication passage 104 communicates with the outside air through the air intake chamber 103. When sucking, the negative pressure in the air outlet channel 102 and the atomizing cavity 101 is larger, the aerosol generating substrate is sucked out from the liquid storage cavity 110 through the micropores on the heating element 121 by the larger negative pressure, at this time, the negative pressure in the liquid storage cavity 110 is increased, and the external air enters the liquid storage cavity 110 through the air inlet cavity 103, the communication channel 104 and the ventilation pinhole 1315, so that ventilation is completed. That is, in the ventilation mode provided in the present application, the communication channel 104 is communicated with the air inlet cavity 103, instead of the air outlet channel 102 or the atomization cavity 101, and the negative pressure of the air inlet cavity 103 is smaller than that of the atomization cavity 101 and the air outlet channel 102, so that ventilation is easier.

The liquid storage cavity 110 is ventilated through the communication channel 104 and the ventilation needle hole 1315, which are arranged as described above, compared with the prior art, the ventilation is easier, so that the sufficient supply of aerosol generating substrate of the heating element 121 of the heating element 12 is ensured, and the burning and dry burning caused by insufficient liquid supply of the heating element 121 are avoided.

With continued reference to fig. 4, the end surface of the heat generating component 12 adjacent to the top wall of the housing portion 131 is spaced from the inner surface of the top wall of the housing portion 131 to form a gap 105 having capillary force, and the atomizing chamber 101 communicates with the ventilation needle hole 1315 through the gap 105.

Specifically, the outer surface of the heat generating component 12 is provided with a third groove (not shown), and the third groove cooperates with the inner surface of the accommodating portion 131 to form the liquid guiding channel 106. The first end of the liquid guide channel 106 is communicated with the gap 105, and the second end of the liquid guide channel 106 is communicated with the ventilation needle hole 1315; that is, the atomizing chamber 101 communicates with the ventilation needle hole 1315 through the gap 105 and the liquid guide passage 106. In this embodiment, the side wall of the supporting member 125 of the heating component 12 far from the pressing member 124 is provided with a third groove, that is, the surface of the side wall of the supporting member 125 far from the pressing member 124 cooperates with the inner surface of the accommodating portion 131 to form the liquid guiding channel 106.

When sucking, aerosol condenses or aerosol generating substrate leaks from the heating element 121 to the atomizing cavity, and can be guided to the liquid guide channel 106 by the capillary force of the gap 105, and then flows to the ventilation pinhole 1315 through the liquid guide channel 106, and when ventilation, part of leaked liquid can be sucked back to the liquid storage cavity 110, so that the suction leakage is avoided.

The cross-sectional area of the liquid-guiding passage 106 is smaller than the cross-sectional area of the communication passage 104. Optionally, the depth and/or width of the third groove forming the liquid guiding channel 106 is smaller than the depth and/or width of the second groove forming the communication channel 104. Through the above arrangement, leakage in the liquid guide passage 106 is prevented from flowing out of the communication passage 104.

It will be appreciated that the ventilation method provided by the present application through the ventilation needle hole 1315 and the communication passage 104 may be applied not only to an embodiment in which the atomizing surface of the heat generating body 121 is parallel to the axis of the atomizer 1, but also to an embodiment in which the atomizing surface of the heat generating body faces downward or upward. The manner of sucking the suction leakage back into the liquid storage cavity 110 through the gap 105, the liquid guide channel 106 and the ventilation needle hole 1315 provided by the application can be applied to an embodiment that the atomizing surface of the heating element 121 is parallel to the axis of the atomizer 1, and also can be applied to an embodiment that the atomizing surface of the heating element faces downwards or upwards.
