Referring to fig. 4, 6 and 8, in some embodiments, the bottom cover 200 is formed with an air guide cavity 230, and the air guide cavity 230 is actually an open cavity. The bottom cover 200 has a mounting surface 210, the mounting surface 210 being disposed toward the atomizing core 100, and in colloquial terms, the mounting surface 210 is actually a bottom wall surface of the air guide chamber 230.

The air inlet channel 500 is arranged in the convex column 220, the lower end of the air inlet channel 500 penetrates through the outer surface of the bottom cover 200 to be directly communicated with the outside, the upper end of the air inlet channel 500 penetrates through the free end surface 223, so that the output port 510 is formed on the free end surface 223, obviously, the output port 510 of the air inlet channel 500 is arranged above the mounting surface 210 and higher than the mounting surface 210. After the external air enters the air intake channel 500, the external air enters the input port 611 of the air intake channel 600 through the output port 510 and the air guide cavity 230 in sequence.

The bottom cover 200 is formed with a reservoir 241, and the reservoir 241 may be formed in various ways. For example, the bottom cover 200 may further include a protruding strip 240, the protruding strip 240 is connected to the mounting surface 210, the protruding strip 240 protrudes a certain height relative to the mounting surface 210, the protruding height of the protruding strip 240 relative to the mounting surface 210 is smaller than the protruding height of the protruding column 220 relative to the mounting surface 210, and the liquid storage groove 241 is formed between two adjacent protruding strips 240. For another example, a portion of the mounting surface 210 may be recessed downward by a certain depth to form the reservoir 241. For another example, the liquid storage groove 241 may be formed by providing the convex strip 240 and recessing the mounting surface 210 at the same time.

Referring to fig. 7, the number of the convex columns 220 may be two, the two convex columns 220 may have substantially the same size, and each convex column 220 is provided therein with an air inlet passage 500, so that the number of the air inlet passages 500 is two, and the air inlet passages 500 may be circular holes. The two convex columns 220 are respectively marked as a first convex column and a second convex column, a first inclined plane 221 is arranged on the first convex column, and the first inclined plane 221 and a free end face 223 on the first convex column are connected to form an obtuse included angle. Therefore, in a direction in which the atomizing core 100 is directed toward the bottom cover 200, i.e., in a direction from top to bottom, the distance from the first inclined surface 221 to the central axis of the first in-cylinder air intake passage 500 gradually increases. Similarly, a second inclined surface 222 is disposed on the second convex pillar, the second inclined surface 222 and a free end surface 223 on the second convex pillar are connected to form an obtuse included angle, and a distance from the second inclined surface 222 to a central axis of the air inlet channel 500 in the second convex pillar gradually increases along a direction from top to bottom. The first inclined surface 221 and the second inclined surface 222 are arranged at intervals in the horizontal direction, the distance between the first inclined surface 221 and the second inclined surface 222 is the distance between the first convex column and the second convex column, and the distance between the first inclined surface 221 and the second inclined surface 222 is gradually reduced along the direction from top to bottom, so that the distance between the first convex column and the second convex column is gradually reduced. According to the actual requirement, the number of the convex columns 220 can be increased or decreased, for example, the number of the convex columns 220 can be one, three or four.

Referring to fig. 3 and 5, in some embodiments, the sealing element 300 includes a silicone sealing element, that is, the sealing element 300 is made of a silicone material, which may provide a certain flexibility to the sealing element 300. The sealing member 300 may be fitted over 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 covers the air guide chamber 230.

Referring to both fig. 7 and 9, the seal 300 has an upper surface 310 and a lower surface 320, with the upper surface 310 and the lower surface 320 facing in opposite directions, the upper surface 310 being disposed toward the atomizing core 100 and the lower surface 320 being disposed toward the bottom cap 200. The sealing member 300 includes an upper projection 330 and a lower projection 340, the upper projection 330 being connected to the upper surface 310, the upper projection 330 projecting upward at a height with respect to the upper surface 310. For example, the lower end of the upper boss 330 is fixedly connected to the upper surface 310, the upper end of the upper boss 330 protrudes to 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 toward the atomizing core 100, so that the upper end surface 331 and the upper surface 310 are vertically spaced apart, and the upper end surface 331 is located above the upper surface 310. The cross-sectional size of the upper boss 330 may gradually increase in a direction from top to bottom to form a table, and of course, the cross-sectional size of the upper boss 330 may remain unchanged and form a cylinder. A portion of the first air channel 610 is located inside the upper boss 330, and the first air channel 610 penetrates the upper end surface 331 to form an outlet 612, i.e. the outlet 612 is located on the upper end surface 331. The first air passage 610 is communicated with the second air passage 620 through the outlet port 612, and the gas entering the first air passage 610 finally flows out of the outlet port 612, so that the gas in the first air passage 610 flows into the second air passage 620 through the outlet port 612.

The sealing member 300 may have a sink 311 formed thereon, the sink 311 being used to store liquid, and the sink 311 may be formed in various manners. For example, a portion of the upper surface 310 may be recessed downward by a certain depth to form the sink 311. For another example, the sealing member 300 may further include a protrusion connected to the upper surface 310, the protrusion protruding from the upper surface 310 by a height smaller than the height of the protrusion of the upper projection 330 from the upper surface 310, and the sunken groove 311 is formed between two adjacent protrusions. For another example, the sinking groove 311 may be formed by both the protrusion and the recess of the upper surface 310.

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 to the lower surface 320, the lower end of the lower boss 340 protrudes a certain height from 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, so that the lower end surface 341 and the lower surface 320 are vertically spaced apart, and the lower end surface 341 is located below the lower surface 320. The cross-sectional dimension h of the lower boss 340 may gradually decrease in a direction from top to bottom to form a frustum shape, and of course, the cross-sectional dimension of the lower boss 340 may be maintained to be a cylindrical shape. The other part 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 guide chamber 230 of the bottom cover 200 through the input port 611.

The number of the upper bosses 330 and the lower bosses 340 may be one, and the lower bosses 340 are 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 bosses 340 are simultaneously abutted against the first and second

inclined surfaces

221 and 222. Therefore, the two convex columns 220 have good positioning effect on the installation of the sealing element 300, and the stability and the reliability of the installation of the sealing element 300 are also improved. Meanwhile, along the direction from top to bottom, the cross-sectional dimension of the lower boss 340 gradually decreases, 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 in the installation process, and the two convex columns 220 can smoothly clamp the lower boss 340. When the seal 300 is installed, the input port 611 is closer to the mounting surface 210 than the output port 510, in other words, the input port 611 is located below the output port 510. Meanwhile, the orthographic 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 misaligned state in the horizontal direction. Of course, referring to fig. 12, the distance R between the orthographic projection 611a of the input port 611 on the bottom cover 200 and the orthographic projection 510a of the output port 510 on the bottom cover 200 is greater than zero, and at this time, the orthographic projection 611a of the input port 611 and the orthographic projection 510a of the output port 510 are in a "separated" state. Referring to fig. 13, the distance R between the orthographic projection 611a of the input port 611 on the bottom cover 200 and the orthographic projection 510a of the output port 510 on the bottom cover 200 is equal to zero, and the orthographic projection 611a of the input port 611 and the orthographic projection 510a of the output port 510 are in a "tangent" state. The "out of phase" and "in phase" states described above also enable the input port 611 and the output port 510 to be horizontally misaligned. In other embodiments, both the input port 611 and the output port 510 may be at the same height relative to the mounting surface 210, and the input port 611 may also be above the output port 510.

Referring to fig. 3, 6 and 7, when a user sucks on the suction nozzle 621, the external air firstly enters the air inlet channel 500, then enters the first air channel 610 through the output port 510, the air guide cavity 230 and the input port 611 in sequence, and then enters the second air channel 620 from the output port 612 to carry smoke out of the suction nozzle 621, so that the flow path of the air is approximately a "labyrinth" path. For the leakage liquid formed by the liquid leaked from the atomizing core 100 and the condensate in the whole suction channel 600, when the leakage liquid flows out from the input port 611 of the first air channel 610, because the orthographic projection of the input port 611 on the bottom cover 200 is completely outside the outline of the output port 510, the leakage liquid can be effectively prevented from entering the air inlet channel 500 from the input port 611 through the output port 510, and finally the leakage liquid is prevented from flowing out of the whole atomizer 10 from the air inlet channel 500, so that the atomizer 10 is prevented from leaking. Of course, leakage from the nebulizer 10 is also prevented when the orthographic projection 611a of the input port 611 and the orthographic projection 510a of the output port 510 are in the above-described "separated" state or "tangent" state.

Since the liquid storage tank 241 is formed on the bottom cover 200, the leakage liquid dropping from the input port 611 is stored in the liquid storage tank 241, and when the leakage liquid in the liquid storage tank 241 is saturated, the leakage liquid can overflow to the air guide chamber 230, so that both the liquid storage tank 241 and the air guide chamber 230 can store the leakage liquid. Moreover, the free end surface 223 of the convex column 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, preventing the leakage liquid from entering the air inlet channel 500 through the output port 510 and flowing out of the whole atomizer 10, and preventing the atomizer 10 from leaking.

For the leakage liquid dripping from the input port 611, in the case where the leakage liquid dripping trajectory is a straight line extending in the vertical direction, since the input port 611 and the output port 510 are completely misaligned, it is apparent that the leakage liquid will directly fall into the reservoir 241. When the leakage liquid deviates from the straight dropping track to form drift, because the lower boss 340 is sandwiched between the two convex columns 220 and the input port 611 is located below the output port 510, the convex column 220 will block the leakage liquid, so that the drift leakage liquid cannot enter the output port 510 and flow into the liquid storage tank 241 along the outer surface of the convex column 220, and finally the drift leakage liquid is prevented from entering the air inlet channel 500 from the output port 510 to generate leakage.

Therefore, a part of the leakage liquid drops from the first air passage 610 to the reservoir 241 through the output port 510, and the reservoir 241 stores the part of the leakage liquid to prevent the leakage. Meanwhile, since the upper surface 310 of the sealing member 300 is concavely formed with the sinking groove 311, another part of the leakage liquid cannot drop into the first air channel 610, and the part of the leakage liquid directly drops into the sinking groove 311, so that the sinking groove 311 stores the part of the leakage liquid. Moreover, the upper end surface 331 of the upper boss 330 is located above the upper surface 310, so that the outlet port 612 on the upper end surface 331 is higher than the upper surface 310 by a certain distance, thereby preventing the liquid level of the leakage liquid in the sink tank 311 from being flush with the upper end surface 331 and preventing the leakage liquid from dripping from the first air passage 610 to the reservoir 241 through the outlet port 612. Therefore, 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 excessive leakage liquid, and finally the leakage liquid is prevented from entering the air inlet channel 500 from the output port 510 to generate leakage. Therefore, a part of leakage liquid is stored through the sinking groove 311 on the sealing element 300, and the liquid storage tank 241 cannot store all leakage liquid, so that the storage pressure of the liquid storage tank 241 on the leakage liquid is greatly reduced, and the leakage-proof capability of the atomizer 10 is further improved.

Referring to fig. 10 and fig. 11, the present invention further provides an electronic atomizer 20, wherein the electronic atomizer 20 includes a power source 30 and the atomizer 10, and the atomizer 10 is detachably connected to the power source 30. Since the atomizer 10 has a good leakage prevention 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 into the power supply 30 to corrode the battery and the electronic components, and the service life of the electronic atomization device 20 is prolonged.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
