The number of the protruding columns 220 may be increased or decreased appropriately according to the actual situation, for example, the number of the protruding columns 220 may be one, three, four, or the like.
Referring to fig. 3 and 5, in some embodiments, the seal 300 comprises a silicone seal, i.e., the seal 300 is made of a silicone material, which may provide the seal 300 with a certain flexibility. The sealing member 300 may be sleeved on the bottom cover 200, and the sealing member 300 is simultaneously pressed between the bottom cover 200 and the housing assembly 400, so that the sealing member 300 plays a capping role on the air guide cavity 230.
Referring to fig. 7 and 9 together, the seal 300 has an upper surface 310 and a lower surface 320, both of which are oppositely facing, the upper surface 310 being disposed toward the atomizing core 100 and the lower surface 320 being disposed toward the bottom cover 200. The sealing member 300 includes an upper boss 330 and a lower boss 340, the upper boss 330 being coupled to the upper surface 310, the upper boss 330 protruding upward from the upper surface 310 by a certain height. For example, the lower end of the upper boss 330 is fixedly connected with the upper surface 310, the upper end of the upper boss 330 protrudes a certain height relative to the upper surface 310, the upper end of the upper boss 330 has an upper end surface 331, the upper end surface 331 is also disposed towards the atomizing core 100, so that the upper end surface 331 and the upper surface 310 are disposed at intervals in the vertical direction, and the upper end surface 331 is located above the upper surface 310. The cross-sectional dimension of the upper boss 330 may be gradually increased to be in a mesa shape in the top-down direction, and of course, the cross-sectional dimension of the upper boss 330 may be maintained to be in a column shape. A portion of the first air channel 610 is located in the upper boss 330, and the first air channel 610 penetrates through the upper end face 331 to form an outlet 612, i.e. the outlet 612 is located in the upper end face 331.

The lower boss 340 is connected to the lower surface 320, and the lower boss 340 protrudes downward by a certain height with respect to the lower surface 320. For example, the upper end of the lower boss 340 is fixedly connected with the lower surface 320, the lower end of the lower boss 340 protrudes a certain height with respect to the lower surface 320, the lower end of the lower boss 340 has a lower end surface 341, the lower end surface 341 is disposed toward the bottom cover 200 such that both the lower end surface 341 and the lower surface 320 are disposed at intervals in the vertical direction, and the lower end surface 341 is located below the lower surface 320. The cross-sectional dimension h of the lower boss 340 may be gradually reduced to be in a mesa shape along the top-down direction, and of course, the cross-sectional dimension of the lower boss 340 may be maintained to be in a column shape. Another portion of the first air passage 610 is located in the lower boss 340, the first air passage 610 penetrates the lower end surface 341 to form the input port 611, and the first air passage 610 is communicated with the air guiding cavity 230 of the bottom cover 200 through the input port 611.
The number of the upper boss 330 and the lower boss 340 may be one, and the lower boss 340 is interposed in a gap between the two bosses 220 during the installation of the sealing member 300 and the bottom cover 200 such that the lower boss 340 is simultaneously abutted against the first inclined surface 221 and the second inclined surface 222. Therefore, the two bosses 220 play a good role in positioning the installation of the sealing member 300, and also improve the stability and reliability of the installation of the sealing member 300. Meanwhile, the cross-sectional dimension of the lower boss 340 gradually decreases in the top-down direction, and the distance between the first inclined surface 221 and the second inclined surface 222 decreases, so that the lower boss 340 can be smoothly inserted into the gap between the first inclined surface 221 and the second inclined surface 222 during the installation process, thereby ensuring that the two bosses 220 smoothly form a clamping effect on the lower boss 340. When the seal 300 is installed, the inlet port 611 is closer to the mounting face 210 than the outlet port 510, in other words, the inlet port 611 is located below the outlet port 510. Meanwhile, the front projection of the input port 611 on the bottom cover 200 is located outside the outline of the output port 510, so that both the input port 611 and the output port 510 are in a completely dislocated state in the horizontal direction. Of course, referring to fig. 12, the distance R between the front projection 611a of the input port 611 on the bottom cover 200 and the front projection 510a of the output port 510 on the bottom cover 200 is greater than zero, and at this time, the front projection 611a of the input port 611 and the front projection 510a of the output port 510 are in a "separated" state. Referring to fig. 13, the distance R between the front projection 611a of the input port 611 on the bottom cover 200 and the front projection 510a of the output port 510 on the bottom cover 200 is equal to zero, and at this time, the front projection 611a of the input port 611 is in a "tangential" state with respect to the front projection 510a of the output port 510. The "apart" and "tangential" states described above also enable both the input port 611 and the output port 510 to be horizontally offset. In other embodiments, both the inlet 611 and the outlet 510 may be at the same height relative to the mounting surface 210, and the inlet 611 may be above the outlet 510.
Referring to fig. 3, 6 and 7, when the user sucks at the nozzle 621, the external air first enters the air inlet channel 500, then sequentially enters the first air channel 610 through the output port 510, the air guiding cavity 230 and the input port 611, and then enters the second air channel 620 from the output port 612 to carry the smoke out of the nozzle 621, so that the flow path of the air is approximately a "labyrinth" path. As for the leakage liquid formed by the liquid leaked from the atomizing core 100 and the condensate in the whole air suction channel 600, when the leakage liquid flows out from the input port 611 of the first air channel 610, since the orthographic projection of the input port 611 on the bottom cover 200 is completely located outside the outline of the output port 510, the leakage liquid can be effectively prevented from entering the air suction channel 500 from the input port 611 through the output port 510, and finally the leakage liquid can be prevented from flowing out of the whole atomizer 10 from the air suction channel 500, thereby preventing the atomizer 10 from leaking. Of course, when the front projection 611a of the input port 611 and the front projection 510a of the output port 510 are in the above-described "separated" state or "tangential" state, the nebulizer 10 can be prevented from leaking as well.
Since the liquid storage tank 241 is formed on the bottom cover 200, the leakage liquid dropped from the input port 611 will be stored in the liquid storage tank 241, and when the leakage liquid in the liquid storage tank 241 reaches saturation, the leakage liquid can overflow into the air guide chamber 230, so that both the liquid storage tank 241 and the air guide chamber 230 can store the leakage liquid. And, the free end surface 223 of the boss 220 is located above the mounting surface 210, so that the output port 510 on the free end surface 223 is higher than the mounting surface 210 by a certain distance, thereby preventing the liquid level of the leakage liquid in the liquid storage tank 241 and the air guide cavity 230 from being flush with the free end surface 223, and preventing the leakage liquid from entering the air inlet channel 500 through the output port 510 and flowing out of the whole atomizer 10, thereby preventing the atomizer 10 from leaking.
In the case where the leak drop trajectory of the leak liquid dropped from the input port 611 is a straight line extending in the vertical direction, it is apparent that the leak liquid will directly fall into the liquid reservoir 241 due to the complete misalignment of the input port 611 and the output port 510. When the leakage liquid deviates from the straight drop trajectory to form fall, since the lower boss 340 is sandwiched between the two bosses 220 and the input port 611 is located below the output port 510, the bosses 220 will form a blocking effect on the leakage liquid, so that the leakage liquid of fall cannot enter the output port 510 and flow into the liquid storage tank 241 along the outer surface of the boss 220, and finally leakage liquid of fall is prevented from entering the air inlet channel 500 from the output port 510.
Therefore, a part of the leakage liquid drops from the first air passage 610 to the liquid storage tank 241 through the output port 510, and the liquid storage tank 241 stores the part of the leakage liquid to prevent leakage. Meanwhile, since the upper surface 310 of the sealing member 300 is concavely formed with the sink 311, another portion of the leakage liquid will not drop into the first air passage 610, and the portion of the leakage liquid will drop directly into the sink 311, so that the sink 311 stores the portion of the leakage liquid. And, the upper end surface 331 of the upper boss 330 is located above the upper surface 310, so that the outlet 612 on the upper end surface 331 is higher than the upper surface 310 by a certain distance, so as to prevent the liquid level of the leakage liquid in the sink 311 from being level with the upper end surface 331, and prevent the leakage liquid from dripping from the first air channel 610 into the liquid storage tank 241 through the outlet 612. Thus, the leakage liquid stored in the liquid storage tank 241 and the air guide cavity 230 can not be excessive, the liquid level of the leakage liquid is prevented from being flush with the free end surface 223 due to the excessive leakage liquid, and finally the leakage liquid is prevented from entering the air inlet channel 500 from the output port 510. Therefore, a part of leakage liquid is stored in the sinking groove 311 on the sealing member 300, and the liquid storage groove 241 does not store all leakage liquid, so that the storage pressure of the liquid storage groove 241 on the leakage liquid is greatly reduced, and the leakage prevention capability of the atomizer 10 is further improved.
Referring to fig. 10 and 11, the present invention further provides an electronic atomization device 20, where the electronic atomization device 20 includes a power supply 30 and the atomizer 10, and the atomizer 10 is detachably connected to the power supply 30. Since the atomizer 10 has a good leakage preventing capability, on the one hand, waste of liquid due to leakage can be avoided. On the other hand, the leakage liquid can be prevented from invading the power supply 30 to erode the battery and electronic components, and the service life of the electronic atomizing device 20 can be prolonged.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
