The base 60 is fixedly connected with the fixing bracket 30, and specifically, as shown in fig. 4 to 6, outer wall surfaces of both side portions of the flow guiding portion 31 protrude outwards to form a flange 323, a first receiving area 341 is formed between the left flange 323 and the first side wall 313, and a second receiving area 342 is formed between the right flange and the second side wall 314.

Referring to fig. 3 and 8, on both sides of the air inlet 80, the bottom surface 61 is at least partially recessed to form two circular second grooves 67, the bottom end of the electrode 90 has a fixed end 91, and the outer diameter of the fixed end 91 is larger than the outer diameter of the electrode main body 92 extending longitudinally. The fixing end 91 is fixed in the second groove 67, and the electrode mounting hole 66 is located on the second groove 67. At least part of the surface of the second groove 67 is recessed to form a third groove 68, the third groove 68 defines a second air flow channel 82, and the second air flow channel 82 extends transversely along the short axis of the housing 10 and is located on the straight line where the air inlet 80 extends transversely. The air inlet end of the second air flow channel 82 is communicated with the third air flow channel 81, and external air can enter the third air flow channel 81 along the short axis direction of the housing 10 through the air inlet 80 and then enter the second air flow channel 82.
The housing 10 is further provided with at least one first air flow passage 83 for communicating the atomizing chamber 24 with the second air flow passage 82, and the first air flow passage 83 extends along the air inlet 80 toward the atomizing chamber 24. Furthermore, a ventilation column 69 is disposed in the main body 62 near each of the two sides, the left and right ventilation columns 69 define a first airflow channel 83, the air inlet end of the ventilation column 69 is transversely covered by the fixed end 91 of the electrode column, and the external air flows through the air inlet 80, bypasses the third airflow channel 81, enters the second airflow channel 82, flows transversely, enters the first airflow channel 83, flows longitudinally, and enters the atomization chamber 24. Because the second air flow channels 82 are disposed on two sides of the base 60 and have a certain height from the bottom surface of the accommodating cavity 622, the condensate formed when the aerosol in the atomizing cavity 24 is cooled is difficult to enter the second air flow channels 82 and leak outwards.
The outside air current gets into in the atomizing chamber 24 from the first air current channel 83 of both sides, causes the temperature of heating element 24 both sides low easily, and the region in the middle of heating element 24 is because outside air current is difficult to assemble, and the temperature is higher, because the main component of liquid matrix is glycerine, glycerine decomposes the anomaly under high temperature and can produce formaldehyde, influences the environmental test effect of whole device. In order to avoid the generation of formaldehyde, a gasket 70 is provided in the body accommodating chamber 622. Referring to fig. 3 to 10, specifically, the sealing gasket 70 is disposed above the air outlet end of the first air flow channel 83, substantially covering the entire accommodating cavity 622, and a vent hole 71 is disposed at a middle position of the sealing gasket 70, and the vent hole 71 is disposed opposite to the heating element 22, so as to converge the external air flows at two sides of the first air flow channel 83 and enter the atomizing cavity 24 through the vent hole 71.

More specifically, two through holes 72 are further provided on both sides of the vent hole 71 so that the two electrodes 90 axially penetrate through the sealing gasket 70 to be connected with the atomizing assembly 20, and the plane of the two through holes 72 is higher than the plane of the vent hole 71, so that the plane around the vent hole 71 forms a first buffer zone 73 for condensate. Further, the area between the gasket 70 and the base 60 forms a second buffer 74 of condensate. To promote the condensate to enter the first buffer zone 73, the flow guide portion 16 is disposed on both the base main body portion 62 and the gasket 70. Specifically, the inner wall surfaces of the main body portion 62 facing the two sides of the first buffer area 73 are provided with first diversion inclined surfaces 161, the inner wall surfaces of the gasket 70 facing the two sides of the first buffer area 73 are further provided with second diversion inclined surfaces 162, and the second diversion inclined surfaces 162 receive the first diversion inclined surfaces 161. Condensate in the atomizing chamber 24 may flow along the first guide slope 161, into the second guide slope 162, and into the first buffer area 73. When the amount of the liquid buffered in the first buffer area 73 is excessive, the liquid can flow into the second buffer area 74 through the vent hole 71. And because the bottom end face of the second buffer area 74 defined by the main body portion 62 is completely closed, the air outlet ends of the first air flow channels 83 on both sides are disposed close to the bottom face of the sealing pad 70, and the condensate cannot enter the first air flow channels 83 on both sides. The inner walls of the two sides of the second diversion inclined plane 162 are further provided with diversion grooves 163 longitudinally communicated with the second buffer area 74, and the wall surfaces of the two sides of the sealing gasket 70 are symmetrically provided with two second diversion inclined planes 162 and four diversion grooves 163, so that the condensate or the leaked liquid matrix in the atomization cavity 24 can be smoothly guided into the first buffer area 73 and the second buffer area 74.
Referring to fig. 11, another preferred embodiment is provided, which is different from the above embodiment in that the first air flow channel 83 is defined by the housing 10 and the base 20, the bottom end of the first air flow channel 83 extends longitudinally through the bottom surface 61 of the base, and the external air can enter through the second air inlet 831 at the bottom end surface of the first air flow channel 83 and can also enter through the second air flow channel 82 transversely communicated with the first air flow channel 83 to be collected into the first air flow channel 83. When the atomizer 100 is connected to the power supply device 200, the second air inlet 831 of the first air flow channel 83 is covered and sealed by the solid part on the connecting end surface of the power supply device 200 due to the arrangement on the bottom surface 61, and the air flow inductive switch in the power supply device 200 senses the change of the suction air pressure inside the atomizer 100 through the air pressure detection channel communicated with the air inlet 80, so as to control the working state of the aerosol generating device.
In the above atomizer 100, since the air inlet 80 is completely isolated from the first buffer area 73 and the second buffer area 74, condensate cannot leak to the outside of the atomizer 100 through the air inlet 80. The outside air flows laterally into the first air flow passages 83 on both sides through the air inlet 80. Further, in order to improve the whole atomization effect inside the atomization chamber 24, the local temperature on the atomization surface 212 is prevented from being too high, formaldehyde is generated, the gas inside the first airflow channels 83 on the two sides is collected and enters the atomization chamber 24 through the air vent 71 right opposite to the heating element 22, the external airflow is uniformly diffused into the whole atomization chamber 24, the local temperature on the atomization surface 212 is not too high, the generation of excessive atomization products such as formaldehyde is greatly reduced, and the atomization efficiency and the environment test effect of the whole atomizer 100 are 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.
