In addition, through the action of the blocking member 3, it is possible to avoid the collision of the airflows of the two atomization chambers when they flow to the air outlet channel 12.

[0029] It should be noted that the horizontal Figure 2 and Figure 3 The direction of the X axis is vertical. Figure 2 and Figure 3 The direction of the Z axis.

[0030] Furthermore, the blocking member 3 is integrally formed on the liquid storage member 1 or the bottom bracket 2, which can simplify the assembly process.

[0031] In some embodiments, in the longitudinal direction, the blocking member 3 can extend from the end of the air outlet channel 12 away from the bottom bracket 2 to the bottom bracket 2, through the atomization space 4, and extend to the bottom bracket 2, so that the blocking member 3 can separate the air outlet channel 12 into a first air outlet channel 121 and a second air outlet channel 122 arranged in the transverse direction; and separate the atomization space 4 into a first atomization chamber 41 and a second atomization chamber 42 arranged in the transverse direction. At the same time, due to the one-piece molding, the assembly can be simplified.

[0032] In some embodiments, in the longitudinal direction, the blocking member 3 can extend from one end of the bottom bracket 2 toward the liquid storage member 1, through the atomization space 4, and extend to the end of the air outlet channel 12 away from the bottom bracket 2, which can also achieve the separation function of the blocking member 3 and simplify assembly.

In the longitudinal direction, the other end of the blocking member 3 is flush with the end of the atomization space 4 away from the liquid storage cavity, or protrudes from the end of the atomization space 4 away from the liquid storage cavity.

[0034] Furthermore, in some specific embodiments, the blocking member 3 is integrally formed on the liquid storage member 1 , and a receiving groove 21 is provided at one end of the bottom bracket 2 facing the liquid storage member 1 , and one end of the blocking member 3 extends into the receiving groove 21 .

[0035] Specifically, the blocking member 3 may be a blocking plate. In the longitudinal direction, in the air outlet channel 12, the blocking member 3 extends from the end of the air outlet channel 12 away from the bottom bracket 2 toward the accommodating groove 21, and extends to the accommodating groove 21. Therefore, when the liquid storage member 1 and the bottom bracket 2 are assembled, the blocking member 3 can facilitate the docking and matching of the liquid storage member 1 and the bottom bracket 2, so that the first liquid storage cavity 11 and the first air outlet 121 of the liquid storage member 1 can correspond to the first atomization cavity 41 defined by the liquid storage member 1 and the bottom bracket 2, and the second liquid storage cavity 13 and the second air outlet 122 can correspond to the second atomization cavity 42, thereby improving the assembly efficiency.

[0037] Specifically, the accommodating groove 21 opens toward the air outlet channel 12 and the atomizing space 4, and the blocking member 3 extends to the accommodating groove 21. By forming a gap between the inner wall surface of the accommodating groove 21 and the outer wall surface of the blocking member 3, a liquid storage space can be formed in the accommodating groove 21.

[0041] In some embodiments, a side wall on one side of the blocking member 3 is provided with a liquid guiding structure 31 , and the liquid guiding structure 31 can guide the condensed liquid formed on the side wall into the receiving groove 21 , so that the condensed liquid on the side wall is quickly collected in the receiving groove 21 .

[0042] Furthermore, the liquid guiding structure 31 includes a drainage groove extending in the longitudinal direction.

[0043] Specifically, the drainage groove extends in the longitudinal direction, and the transverse cross-sectional shape of the drainage groove can be C-shaped, (-shaped, V-shaped, [-shaped, etc. The condensate on the blocking member 3 will flow to the receiving groove 21 under the action of gravity, and the side wall of the drainage groove can not only drain the condensate, but also accelerate the flow of the condensate, so that the condensate is accelerated to gather in the receiving groove 21.

[0044] Furthermore, the groove is a capillary groove.

[0045] Furthermore, under the combined action of the capillary force of the capillary groove and gravity, more condensate on the blocking member 3 can flow to the drainage groove, so that more condensate can eventually flow to the receiving groove 21, further preventing leakage of the electronic atomization device.

[0046] Furthermore, the top of the bottom bracket 2 is also provided with a accommodating space, and a partition 22 arranged in the accommodating space and protruding toward the air outlet channel 12, and the partition 22 divides the accommodating space laterally into a first liquid collecting tank 23 opposite to the first atomization chamber 41, and a second liquid collecting tank 24 opposite to the second atomization chamber 42; wherein the accommodating tank 21 is arranged on the partition 22.

[0047] Specifically, the top of the bottom bracket 2 includes a peripheral side wall assembled and connected to one end of the liquid storage member 1, a bottom side wall connected to the peripheral side wall, a receiving space formed by the peripheral side wall and the bottom side wall, and a partition 22 protruding in the receiving space and longitudinally toward the air outlet channel 12, and the partition 22 includes two sub-partitions distributed in the accommodating space along the transverse direction, one of which is enclosed with the adjacent side wall to form a first liquid collecting tank 23 opposite to the first atomization chamber 41, and the other sub-partition is enclosed with the adjacent side wall to form a second liquid collecting tank 24 opposite to the second atomization chamber 42. The first liquid collecting tank 23 can be used to collect condensate or leakage formed by the first atomization core 5 in the first atomization chamber 41, and the second liquid collecting tank 24 can be used to collect condensate or leakage formed by the second atomization core 6 in the second atomization chamber 42. In addition, a receiving tank 21 is defined between the two sub-partitions, so that there is a gap between the outer side wall of the blocking member 3 and the opposite sides of the two sub-partition plates, which can be used to store condensate.

[0048] Furthermore, a first liquid absorbent member 7 is provided in the first liquid collecting tank 23, and a second liquid absorbent member 8 is provided in the second liquid collecting tank 24. The condensate flowing to the first liquid collecting tank 23 can be absorbed by the first liquid absorbent member 7, and the condensate flowing to the second liquid collecting tank 24 can be absorbed by the second liquid absorbent member 8.

In addition, the external airflow can also flow to the second atomization chamber 42 through the second air inlet 26, take away the aerosol formed in the second atomization chamber 42, and flow to the second air outlet 122, so that the second air inlet 26, the second atomization chamber 42 and the second air outlet 122 form another airflow channel of the electronic atomization device.
