A partition 8 is further arranged between the atomization assembly 4 and the base 7, and a certain distance is kept between the partition 8 and the atomization surface 43. As shown in fig. 4 to 8, the partitioning member 8 includes a recessed portion 81 and first and

second connection portions

82 and 83 symmetrically disposed at both sides of the recessed portion 81 in a length direction of the partitioning member 8, and the first and

second connection portions

82 and 83 are disposed in a stepped shape with both ends of the recessed portion 81. The two sides of the first connecting portion 82 and the second connecting portion 83 abut against the inner side wall of the base 7, and the two sides of the recessed portion 81 also abut against the inner side wall of the base 7. Understandably, the recessed portion 81, the first connecting portion 82 and the second connecting portion 83 can substantially cover the projection plane of the inner cavity of the base 7 on the projection plane of the long axis direction of the atomizing assembly 4.

Two support columns 84 are further provided on the bottom surface of the partition 8 opposite to the base main body 71, and the support columns 84 abut against the base main body 71, so that a certain space is left between the partition 8 and the base 7.

86, 87 so that condensate may flow along first and second drainage surfaces 75, 76 inside the base to first and

second channels

86, 87, respectively.

As shown in FIGS. 4 and 7, since the partition 8 substantially covers the projection surface of the inner cavity of the base 7, at least one vent hole 88 is provided in the partition 8 to communicate the atomizing chamber 5 with the first air flow path 71 of the base. The vent hole 88 may be combined with a through-going through-hole 85 partly receiving the electrode shaft 11, designed as two larger through-holes, so that there is still enough space to allow the gas flow to pass after receiving the electrode shaft 11. Preferably, the vent hole 88 is separately provided on the recess 81. The air outlet end of the vent hole 88 is provided for the peripheral surface of the convex recess 81 so that the condensate buffered in the recess 81 does not flow out through the vent hole 88. Two independent fine vent holes 88 are formed in the recessed portion 81, the vent holes 88 and the first air inlet 74 are arranged in a staggered mode along the long axis direction, air flow can enter the vent holes 88 after entering the first air inlet 74 and needs to be bent, the air flow path is prolonged, and condensate is made to be more difficult to enter the first air inlet 74 through the vent holes 88.

Along the width direction of the recessed portion 81, the width of the recessed portion 81 is larger than the width of the atomizing element 62, and the opening directions of the first flow guide surface 75 and the second flow guide surface 76 which guide the flow inside the base 7 are opposite to the atomizing assembly 4. The extending directions of the first flow guiding groove 86 and the second flow guiding groove 87 on the partition member are substantially parallel to the extending direction of the atomizing surface 43, or the extending directions of the first flow guiding groove 86 and the second flow guiding groove 87 are at least partially substantially parallel to the extending direction of the atomizing surface 43, so that the condensed liquid after the condensation of the aerosol formed in the atomizing cavity 5 can smoothly flow into the first flow guiding groove 86 and the second flow guiding groove 87 through the first flow guiding surface 75 and the second flow guiding surface 76, respectively.

Referring to fig. 5 and 6, the first and

second connection portions

82 and 83 leave a space with the main body of the base 7, forming the first and second

condensate collecting regions

121 and 122. The openings at both ends of the first guide groove 86 and the second guide groove 87 communicate with the first condensate collecting region 121 and the second condensate collecting region 122, respectively. The first and second

condensate collection regions

121 and 122 may be internally filled with a capillary element 13, such as an oil absorbent cotton or the like. The condensate flows into the condensate collecting areas at two sides through the openings at two ends of the first diversion trench 121 and the second diversion trench 122, and is absorbed and stored by the oil absorption cotton. The bottom end surface of the base main body 71 and the bottom surface of the partition recessed portion 81 are provided with a space, and a third condensate collecting region 123 is formed in the inner space of the base main body 71 not exceeding the height of the outlet end surface of the first inlet port 74. The third condensate collection region 123 may fill the capillary element 13, which may be an oil absorbent cotton. The first condensate collecting region 121 and the second condensate collecting region 122 are located above the third condensate collecting region 123, and communicate with the third condensate collecting region 123. When the capillary elements 13 within the first and second

condensate collecting regions

121, 122 absorb sufficient condensate, the condensate is allowed to flow by gravity into the third condensate collecting region 123.

In accordance with still another preferred embodiment of the present invention, as shown in fig. 9 to 11, unlike the above-described examples, the vent hole 88 provided in the partition recessed portion 81 is an elongated vent hole, the end face of the air outlet end of the vent hole 88 is higher than the surrounding surface, and the vent hole 88 at least partially covers the cross section of the first air inlet 74 on the projection plane perpendicular to the long axis direction. In a more preferable scheme, a hollow boss is arranged on the end face of the recessed portion 81 facing the base main body 71, the inner cavity of the boss can form a part of the accommodating space of the first air inlet 74, and the corresponding first air inlet 74 is arranged in an elongated manner, so that the air outlet end of the first air inlet 74 is abutted against the bottom face of the recessed portion 81. The surface around the air outlet end of the vent hole 88 is obliquely arranged towards the first diversion trench 86 and the second diversion trench 87 respectively, so that the vent hole 88 forms a raised island and an inclined surface extending from the air outlet end of the vent hole 88 to the first diversion trench 86 and the second diversion trench 87 is formed. The condensate cached in the concave portion 81 can only flow to the first diversion groove 86 and the second diversion groove 87 along the inclined surfaces at the two sides of the vent hole 88, and cannot flow over the air outlet end surface of the vent hole 88. In this embodiment, since the air outlet end surface of the first air inlet 74 and the recessed portion 81 are configured to abut against each other along the long axis direction of the atomizer, the space between the bottom end surface of the base main body 71 and the bottom surface of the recessed portion 81 of the partition member can form the fourth condensate collecting region 124, and the condensate collecting region inside the base main body 7 is greatly enlarged. The fourth condensate 124 collection zone may fill the capillary element 13. Referring to fig. 9 and 10, the condensate enters the first channel 86 and the second channel 87, and may flow through the openings on both sides into the fourth condensate collecting region 124 to be absorbed and stored by the capillary element 13.

The atomizing component 4 buffers the condensate formed in the atomizing cavity 5 through the concave part 81 of the separating component, and the accumulated condensate can further flow to the guide grooves on the two sides and enter the condensate collecting area between the separating component 8 and the base 7 through the guide grooves. By filling the condensate collecting region with the capillary element 13, condensate can be absorbed. Because the inner cavity of the base 7 and the peripheral surface of the air outlet end of the vent hole 88 positioned in the concave part 81 of the separating part are both provided with drainage inclined planes, condensate is directly introduced into the diversion trench, and the air outlet end of the vent hole 88 is higher than the peripheral surface, so that the condensate cannot flow out through the vent hole 88. Meanwhile, as the partition 8 covers the whole atomizing cavity 5 on the projection plane of the long axis direction of the atomizing device 4, the aerosol generated in the atomizing cavity 5 can not be absorbed by the capillary element 13 filled in the condensate collecting area, and the atomizing capacity of the atomizing device is also improved.

It should be noted that the description and drawings of the present application illustrate preferred embodiments of the present application, but are not limited to the embodiments described in the present application, and further, those skilled in the art can make modifications or changes according to the above description, and all such modifications and changes should fall within the scope of the claims appended to the present application.
