- the protruding strips are connected to the mounting surface and protrude from the mounting surface.
- a liquid storage groove capable of storing the liquid is formed between the protruding strips.
- the mounting surface is recessed to form a liquid storage groove capable of storing the liquid.

- the other end of the lower protruding portion has a lower end surface.
- the lower end surface is spaced apart from the lower surface; and the inlet port is located at the lower end surface.
- the inlet port can be closer to the mounting surface than the outlet port, so as to effectively prevent the floating leakage liquid due to the deviation from the straight dropping trajectory from entering the inlet port, to prevent leakage.

- An electronic atomizing device includes a power supply and the atomizer according to any one of the above.
- the atomizer is detachably connected to the power supply. When the liquid in the atomizer is completely consumed, this atomizer can be replaced with a new one, to cooperate with the power supply, so that the power supply can be recycled.
- the leakage liquid formed by the liquid leaked from the atomizing core and the liquor condensate in the entire vaping channel when the leakage liquid flows out from the inlet port of the vaping channel, since the orthographic projection of the inlet port on the bottom cover is completely outside the outline of the outlet port, the leakage liquid can be effectively prevented from entering the air intake channel via the inlet port through the outlet port, and finally, the leakage liquid can be prevented from flowing out of the entire atomizer via the air intake channel, so as to prevent the atomizer from leaking.

- the outside air when the user vapes at the nozzle 621, the outside air first enters the air intake channel 500, and then passes through the outlet port 510, the air guiding cavity 230 and the inlet port 611 in sequence, and enters the first air channel 610, and then enters the second air channel 620 from the guiding outlet 612 to carry the aerosol out of the nozzle 621. Therefore, the flow trajectory of the air is roughly a "labyrinth" trajectory.
- the leakage liquid formed by the liquid leaked from the atomizing core 100 and the liquor condensate in the entire vaping channel 600 when the leakage liquid flows out from the inlet port 611 of the first air channel 610, since the orthographic projection of the inlet port 611 on the bottom cover 200 is completely outside the outline of the outlet port 510, the leakage liquid can be effectively prevented from entering the air intake channel 500 via the inlet port 611 through the outlet port 510, and finally, the leakage liquid can be prevented from flowing out of the entire atomizer 10 via the air intake channel 500, so as to prevent the atomizer 10 from leaking.
- the atomizer 10 can also be prevented from leaking.
- the leakage liquid dropping from the inlet port 611 will be stored in the liquid storage groove 241.
- the leakage liquid in the liquid storage groove 241 reaches saturation, the leakage liquid can overflow to the air guiding cavity 230, and thus, both the liquid storage groove 241 and the air guiding cavity 230 can store the leakage liquid.
- the free end surface 223 of the protruding post 220 is located above the mounting surface 210, so that the outlet 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 groove 241 and the air guiding cavity 230 from being flush with the free end surface 223, to prevent the leakage liquid from flowing out of the entire atomizer 10 by entering the air intake channel 500 through the outlet port 510, thereby preventing the atomizer 10 from leaking.
- a part of the leakage liquid drops into the liquid storage groove 241 through the outlet port 510 from the first air channel 610, and the liquid storage groove 241 stores the part of the leakage liquid to prevent leakage.
- the upper surface 310 of the sealing member 300 is recessed to form the sunken groove 311, another part of the leakage liquid will not be able to drop into the first air channel 610, and this part of the leakage liquid will drop directly into the sunken groove 311, so that the sunken groove 311 stores this part of the leakage liquid.
- the upper end surface 331 of the upper protruding portion 330 is located above the upper surface 310, so that the guiding outlet 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 sunken groove 311 from being flush with the upper end surface 331 to prevent the leakage liquid from dropping into the liquid storage groove 241 through the first air channel 610 via the guiding outlet 612.
- the leakage liquid stored in the liquid storage groove 241 and the air guiding cavity 230 will not be too much, so as to prevent the liquid level of the leakage liquid from being flush with the free end surface 223 due to excessive leakage liquid, and finally prevent the leakage occurring when the leakage liquid enters the air intake channel 500 from the outlet port 510. Therefore, a part of the leakage liquid is stored in the sunken groove 311 on the sealing member 300, and the liquid storage groove 241 will not store all the leakage liquid, thereby greatly reducing the storage burden of the liquid storage groove 241 for the leakage liquid, and further improving the anti-leakage capability of the atomizer 10.

Chinese Patent Application No. 202010974502.X, filed on September 16, 2020 - The present application relates to the field of atomizing technologies, in particular to an atomizer and an electronic atomizing device including the atomizer.
- There are dozens of carcinogenic substances in aerosols formed by burning atomized media. For example, tar will cause great harm to human health, and the aerosols will diffuse in the air to form second-hand aerosols, which will be harmful to the human body after inhalation by the surrounding people. Therefore, smoking is expressly prohibited in most public places. However, electronic atomizing devices usually do not contain harmful components such as tar, suspended particles and others, so the electronic atomizing devices are widely used.
- The electronic atomizing device generally includes an atomizer and a power supply. When the electronic atomizing device is out of use, e-liquid or the liquor condensate stored in the atomizer will leak from the bottom of the atomizer to the power supply, and the leaked e-liquid or liquor condensate will erode the power supply, thereby affecting the life of the power supply.
- According to various embodiments of the present application, an atomizer and an electronic atomizing device including the atomizer are provided.
- An atomizer includes an atomizing core and a bottom cover. The atomizer is provided with a vaping channel. At least a part of the atomizing core is located in the vaping channel. The atomizing core is configured to temporally store liquid, and atomize the liquid to form an aerosol that is dischargeable into the vaping channel. The bottom cover is provided with an air intake channel. The air intake channel has an outlet port through which air flows out. The vaping channel has an inlet port through which the air flows in. Outside air entering the air intake channel passes through the outlet port and the inlet port in sequence, and then enters the vaping channel to carry the aerosol. An orthographic projection of the inlet port on the bottom cover is located outside an outline of the outlet port.
- In one of the embodiments, the bottom cover is further provided with an air guiding cavity. The bottom cover has a mounting surface defining a part of a boundary of the air guiding cavity and disposed toward the inlet port, and further includes a protruding post located in the air guiding cavity. One end of the protruding post is connected to the mounting surface, and the other end of the protruding post protrudes from the mounting surface and has a free end surface. The free end surface is spaced apart from the mounting surface. The air intake channel is disposed in the protruding post. The outlet port is located at the free end surface. The outside air passes through the outlet port and the air guiding cavity in sequence, and then enters the inlet port. In this way, the outlet port on the free end surface is higher than the mounting surface by a certain distance, thereby preventing the liquid level of the leakage liquid from being flush with the free end surface, to prevent the leakage liquid from flowing out of the entire atomizer by entering the air intake channel through the outlet port, thereby preventing the atomizer from leaking.
- In one of the embodiments, the bottom cover further includes protruding strips. The protruding strips are connected to the mounting surface and protrude from the mounting surface. A liquid storage groove capable of storing the liquid is formed between the protruding strips. And/or, the mounting surface is recessed to form a liquid storage groove capable of storing the liquid. By disposing the liquid storage groove, the space of the bottom cover for storing the leakage liquid can be increased.
- In one of the embodiments, the inlet port is closer to the mounting surface than the outlet port. It can effectively prevent the floating leakage liquid due to the deviation from the straight dropping trajectory from entering the inlet port, to prevent leakage.
- In one of the embodiments, a sealing member is further included. The sealing member seals and covers the air guiding cavity. The vaping channel includes a first air channel disposed on the sealing member. The inlet port is located at the first air channel. The sealing member has an upper surface disposed toward the atomizing core. The upper surface is provided with a sunken groove capable of storing the liquid. The sunken groove can store the leakage liquid, which further increases the space for storing the leakage liquid in the entire atomizer.
- In one of the embodiments, the sealing member includes an upper protruding portion. One end of the upper protruding portion is connected to the upper surface, the other end of the upper protruding portion protrudes from the upper surface and has an upper end surface. The upper end surface is spaced apart from the upper surface. A part of the first air channel is located in the upper protruding portion, and has a guiding outlet through which the air is output. The guiding outlet is disposed on the upper end surface. The guiding outlet on the upper end surface can be disposed higher than the upper surface by a certain distance, so as to prevent the liquid level of the leakage liquid from being flush with the upper end surface, and prevent the leakage liquid from dropping into the liquid storage groove of the bottom cover through the guiding outlet from the first air channel.
- In one of the embodiments, the sealing member has a lower surface disposed toward bottom cover. The sealing member includes a lower protruding portion. One end of the lower protruding portion is connected to the lower surface, and the other end of the lower protruding portion protrudes from the lower surface. A part of the first air channel is located in the lower protruding portion. Two protruding posts are provided. The lower protruding portion is clamped between the two protruding posts. By clamping the lower protruding portion between the two protruding posts, the mounting stability of the sealing member can be improved.
- In one of the embodiments, the other end of the lower protruding portion has a lower end surface. The lower end surface is spaced apart from the lower surface; and the inlet port is located at the lower end surface. In this way, the inlet port can be closer to the mounting surface than the outlet port, so as to effectively prevent the floating leakage liquid due to the deviation from the straight dropping trajectory from entering the inlet port, to prevent leakage.
- In one of the embodiments, in a direction in which the atomizing core is directed toward the bottom cover, a distance between the two protruding posts and a cross-sectional size of the lower protruding portion gradually decrease. The mounting efficiency and stability of the sealing member can be improved by the guiding of the wedge-shaped lower protruding portion.
- In one of the embodiments, a housing assembly is further included. The sealing member and the atomizing core are located in the housing assembly. The vaping channel includes a second air channel disposed in the housing assembly and communicating with the first air channel. The aerosol of the atomizing core is discharged to the second air channel. The second air channel is formed with a nozzle on the housing assembly. The housing assembly can protect the atomizing core, and also facilitate the vaping of the user for the aerosol at the nozzle.
- In one of the embodiments, the sealing member includes a silicone sealing member. The silicone sealing member has a certain flexibility, so that the sealing effect of the sealing member can be improved.
- In one of the embodiments, in a direction in which the atomizing core is directed toward the bottom cover, a cross-sectional size of the upper protruding portion gradually increases or remains unchanged.
- In one of the embodiments, the protruding post is provided with an inclined surface. The inclined surface is connected to the free end surface of the protruding post, and an obtuse angle is formed between the inclined surface and the free end surface of the protruding post.
- An electronic atomizing device includes a power supply and the atomizer according to any one of the above. The atomizer is detachably connected to the power supply. When the liquid in the atomizer is completely consumed, this atomizer can be replaced with a new one, to cooperate with the power supply, so that the power supply can be recycled.
- For the leakage liquid formed by the liquid leaked from the atomizing core and the liquor condensate in the entire vaping channel, when the leakage liquid flows out from the inlet port of the vaping channel, since the orthographic projection of the inlet port on the bottom cover is completely outside the outline of the outlet port, the leakage liquid can be effectively prevented from entering the air intake channel via the inlet port through the outlet port, and finally, the leakage liquid can be prevented from flowing out of the entire atomizer via the air intake channel, so as to prevent the atomizer from leaking.

FIGS. 1 ,2 , and3 , anatomizer 10 according to an embodiment of the present invention is configured for atomizing an aerosol-generating substrate such as a liquid to form an aerosol that can be vaped by a user. Theatomizer 10 includes anatomizing core 100, abottom cover 200, a sealingmember 300, and ahousing assembly 400. Thebottom cover 200 is provided at an end of thehousing assembly 400. Both the sealingmember 300 and theatomizing core 100 are disposed inside thehousing assembly 400. Theatomizing core 100 is located above thebottom cover 200. The sealingmember 300 is located between thebottom cover 200 and theatomizing core 100. Thehousing assembly 400 and the sealingmember 300 are provided with avaping channel 600. Thevaping channel 600 includes aninlet port 611. When theatomizer 10 is operated, air first flows into theentire vaping channel 600 from theinlet port 611. Thebottom cover 200 is provided with anair intake channel 500. Theair intake channel 500 communicates with thevaping channel 600 and the outside. Theair intake channel 500 includes anoutlet port 510 corresponding to theinlet port 611. When theatomizer 10 is operated, the air in theair intake channel 500 finally flows out from theoutlet port 510. - The
vaping channel 600 includes afirst air channel 610 and asecond air channel 620. Thefirst air channel 610 is disposed on the sealingmember 300, and thesecond air channel 620 is provided on thehousing assembly 400. Thesecond air channel 620 extends through an outer surface of thehousing assembly 400, thereby forming anozzle 621 on the outer surface. Thenozzle 621 is located at an end of thehousing assembly 400 away from thebottom cover 200. Thesecond air channel 620 communicates with the outside through thenozzle 621. The user can vape the aerosol generated by theatomizer 10 by touching thenozzle 621. A liquid storage cavity is further opened in thehousing assembly 400, and is used for storing liquid. - In some embodiments, at least a part of the
atomizing core 100 is located in thesecond air channel 620, and the liquid storage cavity can supply the liquid to theatomizing core 100. Theatomizing core 100 includes a heating element and a liquid penetrating element. The heating element can be a metal wire, a resistance material, and the like. The liquid penetrating element can be a ceramic material, various fiber materials, cotton or non-woven materials, and the like. Theatomizing core 100 can atomize the liquid supplied by the liquid storage cavity to form the aerosol. The aerosol can be vaped out by the user through thesecond air channel 620. - Referring to
FIGS. 4 ,6 , and8 , in some embodiments, thebottom cover 200 is provided with anair guiding cavity 230. Theair guiding cavity 230 is actually an open cavity. Thebottom cover 200 has a mountingsurface 210. The mountingsurface 210 is disposed toward theatomizing core 100. Generally speaking, the mountingsurface 210 is actually a bottom wall surface of theair guiding cavity 230. Thebottom cover 200 further includes a protrudingpost 220. The protrudingpost 220 is accommodated in theair guiding cavity 230. The protrudingpost 220 is vertically disposed relative to the mountingsurface 210. One end of the protruding post 220 (hereinafter collectively referred to as a lower end of the protruding post 220) is fixedly connected to the mountingsurface 210, and the other end of the protruding post 220 (hereinafter collectively referred to as an upper end of the protruding post 220) protrudes from the mountingsurface 210 by a certain height. The upper end of the protrudingpost 220 includes afree end surface 223. Thefree end surface 223 is spaced apart from the mountingsurface 210 in a vertical direction of the protrudingpost 220, so that thefree end surface 223 is located above the mountingsurface 210. Theair intake channel 500 is disposed in the protrudingpost 220. The lower end of theair intake channel 500 extends through an outer surface of thebottom cover 200 and directly communicates with the outside. The upper end of theair intake channel 500 extends through thefree end surface 223, so that the above-mentionedoutlet port 510 is formed on thefree end surface 223. Obviously, theoutlet port 510 of theair intake channel 500 is located above the mountingsurface 210 and is higher than the mountingsurface 210. After the outside air enters theair intake channel 500, the outside air will pass through theoutlet port 510 and theair guiding cavity 230 in sequence, and then enter theinlet port 611 of thevaping channel 600. - A
liquid storage groove 241 is formed on thebottom cover 200. Theliquid storage groove 241 can be formed in various ways. For example, thebottom cover 200 may further include protruding strips 240. The protruding strips 240 are connected to the mountingsurface 210. The protrudingstrip 240 protrudes from the mountingsurface 210 by a certain height. A protruding height of the protrudingstrip 240 relative to the mountingsurface 210 is less than a protruding height of the protrudingpost 220 relative to the mountingsurface 210. Theliquid storage groove 241 is formed between two adjacent protruding strips 240. For another example, a part of the mountingsurface 210 may be recessed downward by a certain depth to form theliquid storage groove 241. For another example, theliquid storage groove 241 can be formed by disposing the protrudingstrips 240 and recessing the mountingsurface 210. - Referring to
FIG. 7 , two protrudingposts 220 may be provided. The two protrudingposts 220 may have approximately the same size. Each protrudingpost 220 is provided with anair intake channel 500 therein, and thus twoair intake channels 500 are provided. Theair intake channel 500 may be a circular hole. The two protrudingposts 220 are respectively denoted as a first protruding post and a second protruding post. A firstinclined surface 221 is disposed on the first protruding post. The firstinclined surface 221 is connected to thefree end surface 223 of the first protruding post, and thus an obtuse angle is formed between the firstinclined surface 221 and thefree end surface 223 of the first protruding post. Therefore, in a direction in which theatomizing core 100 is directed toward thebottom cover 200, that is, in a direction from top to bottom, a distance from the firstinclined surface 221 to a central axis of theair intake channel 500 in the first protruding post gradually increases. Similarly, a secondinclined surface 222 is disposed on the second protruding post. The secondinclined surface 222 is connected with thefree end surface 223 of the second protruding post, and thus an obtuse angle is formed between the secondinclined surface 222 and thefree end surface 223 of the second protruding post. In the direction from top to bottom, a distance from the secondinclined surface 222 to a central axis of theair intake channel 500 in the second protruding post gradually increases. The firstinclined surface 221 is spaced apart from the secondinclined surface 222 in a horizontal direction. A distance between the firstinclined surface 221 and the secondinclined surface 222 is a distance between the first protruding post and the second protruding post. In the direction from top to bottom, the distance H between the firstinclined surface 221 and the secondinclined surface 222 gradually decreases, so the distance between the first protruding post and the second protruding post gradually decreases. According to actual needs, the number of the protrudingposts 220 can be appropriately increased or decreased, for example, one, three, or four protrudingposts 220 can be provided. - Referring to
FIGS. 3 and5 , in some embodiments, the sealingmember 300 includes a silicone sealing member, that is, the sealingmember 300 is made of a silicone material, so that the sealingmember 300 can have a certain flexibility. The sealingmember 300 can be sleeved on thebottom cover 200. The sealingmember 300 is compressed between thebottom cover 200 and thehousing assembly 400, so that the sealingmember 300 can seal and cover theair guiding cavity 230. - Referring to
FIGS. 7 and9 , the sealingmember 300 has anupper surface 310 and alower surface 320. Theupper surface 310 and thelower surface 320 are facing oppositely. Theupper surface 310 is disposed toward theatomizing core 100, and thelower surface 320 is disposed toward thebottom cover 200. The sealingmember 300 includes an upper protrudingportion 330 and a lower protrudingportion 340. The upper protrudingportion 330 is connected to theupper surface 310, and the upper protrudingportion 330 protrudes upward from theupper surface 310 by a certain height. For example, a lower end of the upper protrudingportion 330 is fixedly connected to theupper surface 310, and an upper end of the upper protrudingportion 330 protrudes from theupper surface 310 by a certain height. The upper end of the upper protrudingportion 330 has anupper end surface 331. Theupper end surface 331 is also disposed toward theatomizing core 100, so that theupper end surface 331 is spaced apart from theupper surface 310 in the vertical direction, and theupper end surface 331 is located above theupper surface 310. In the direction from top to bottom, a cross-sectional size of the upper protrudingportion 330 can gradually increase, so that the upper protrudingportion 330 can be in a shape of truncated cone. Certainly, the cross-sectional size of the upper protrudingportion 330 can remain unchanged to be in a cylindrical shape. A part of thefirst air channel 610 is located in the upper protrudingportion 330. Thefirst air channel 610 extends through theupper end surface 331 to form a guidingoutlet 612. That is, the guidingoutlet 612 is located on theupper end surface 331. Thefirst air channel 610 communicates with thesecond air channel 620 through the guidingoutlet 612. The air entering thefirst air channel 610 finally flows out from the guidingoutlet 612, so that the air in thefirst air channel 610 flows into thesecond air channel 620 via the guidingoutlet 612. -
Sunken grooves 311 may be formed on the sealingmember 300. Thesunken groove 311 is used for storing liquid. Thesunken groove 311 may be formed in various ways. For example, a part of theupper surface 310 may be recessed downward by a certain depth to form thesunken groove 311. For another example, the sealingmember 300 may further include protrusions. The protrusions are connected to theupper surface 310, and protrude from theupper surface 310 by a certain height. The protruding height of the protrusions relative to theupper surface 310 is less than that of the upper protrudingportion 330 relative to theupper surface 310. Thesunken groove 311 is formed between two adjacent protrusions. For another example, thesunken groove 311 can be formed by disposing the protrusions and recessing theupper surface 310. - The
lower protruding portion 340 is connected with thelower surface 320. Thelower protruding portion 340 protrudes downward relative to thelower surface 320 by a certain height. For example, an upper end of the lower protrudingportion 340 is fixedly connected to thelower surface 320, a lower end of the lower protrudingportion 340 protrudes from thelower surface 320 by a certain height. The lower end of the lower protrudingportion 340 includes alower end surface 341. Thelower end surface 341 is disposed toward thebottom cover 200, so that thelower end surface 341 and thelower surface 320 are spaced apart from each other in the vertical direction, and thelower end surface 341 is located below thelower surface 320. In the direction from top to bottom, a cross-sectional size h of the lower protrudingportion 340 may gradually decrease, so that the lower protrudingportion 340 can be in a shape of truncated cone. Certainly, the cross-sectional size of the lower protrudingportion 340 may remain unchanged to be in a cylindrical shape. The other part of thefirst air channel 610 is located in the lower protrudingportion 340. Thefirst air channel 610 extends through thelower end surface 341 to form the above-mentionedinlet port 611. Thefirst air channel 610 communicates with theair guiding cavity 230 of thebottom cover 200 via theinlet port 611. - One upper protruding
portion 330 and one lower protrudingportion 340 may be provided. During mounting the sealingmember 300 and thebottom cover 200, the lower protrudingportion 340 is clamped in a gap between the two protrudingposts 220, so that the lower protrudingportion 340 abuts against the firstinclined surface 221 and the secondinclined surface 222. Therefore, the two protrudingposts 220 play a good role in positioning when mounting the sealingmember 300, and the mounting stability and reliability of the sealingmember 300 are also improved. In addition, in the direction from top to bottom, the cross-sectional size of the lower protrudingportion 340 gradually decreases, and the distance between the firstinclined surface 221 and the secondinclined surface 222 decreases. During the mounting process, the lower protrudingportion 340 can be smoothly inserted in the gap between the firstinclined surface 221 and the secondinclined surface 222 to ensure that the two protrudingposts 220 smoothly form a clamping effect on the lower protrudingportion 340. After the sealingmember 300 is mounted, theinlet port 611 is closer to the mountingsurface 210 than theoutlet port 510, in other words, theinlet port 611 is located below theoutlet port 510. In addition, an orthographic projection of theinlet port 611 on thebottom cover 200 is located outside an outline of theoutlet port 510, so that both theinlet port 611 and theoutlet port 510 are completely misaligned in the horizontal direction. Certainly, referring toFIG. 12 , a distance R between theorthographic projection 611a of theinlet port 611 on thebottom cover 200 and theorthographic projection 510a of theoutlet port 510 on thebottom cover 200 is greater than zero. In this case, theorthographic projection 611a of theinlet port 611 and theorthographic projection 510a of theoutlet port 510 are in a "separated" state. Referring toFIG. 13 , the distance R between theorthographic projection 611a of theinlet port 611 on thebottom cover 200 and theorthographic projection 510a of theoutlet port 510 on thebottom cover 200 is equal to zero. In this case, theorthographic projection 611a of theinlet port 611 and theorthographic projection 510a of theoutlet port 510 are in a "tangent" state. The above-mentioned "separated" and "tangent" states can also cause both theinlet port 611 and theoutlet port 510 to be in a misaligned state in the horizontal direction. In other embodiments, both theinlet port 611 and theoutlet port 510 may be located at the same height relative to the mountingsurface 210, or theinlet port 611 may also be located above theoutlet port 510. - Referring to
FIGS. 3 ,6 , and7 , when the user vapes at thenozzle 621, the outside air first enters theair intake channel 500, and then passes through theoutlet port 510, theair guiding cavity 230 and theinlet port 611 in sequence, and enters thefirst air channel 610, and then enters thesecond air channel 620 from the guidingoutlet 612 to carry the aerosol out of thenozzle 621. Therefore, the flow trajectory of the air is roughly a "labyrinth" trajectory. For the leakage liquid formed by the liquid leaked from theatomizing core 100 and the liquor condensate in theentire vaping channel 600, when the leakage liquid flows out from theinlet port 611 of thefirst air channel 610, since the orthographic projection of theinlet port 611 on thebottom cover 200 is completely outside the outline of theoutlet port 510, the leakage liquid can be effectively prevented from entering theair intake channel 500 via theinlet port 611 through theoutlet port 510, and finally, the leakage liquid can be prevented from flowing out of theentire atomizer 10 via theair intake channel 500, so as to prevent theatomizer 10 from leaking. Certainly, when theorthographic projection 611a of theinlet port 611 and theorthographic projection 510a of theoutlet port 510 are in the above-mentioned "separated" state or "tangent" state, theatomizer 10 can also be prevented from leaking. - Since the
bottom cover 200 is formed with theliquid storage groove 241, the leakage liquid dropping from theinlet port 611 will be stored in theliquid storage groove 241. When the leakage liquid in theliquid storage groove 241 reaches saturation, the leakage liquid can overflow to theair guiding cavity 230, and thus, both theliquid storage groove 241 and theair guiding cavity 230 can store the leakage liquid. In addition, thefree end surface 223 of the protrudingpost 220 is located above the mountingsurface 210, so that theoutlet port 510 on thefree end surface 223 is higher than the mountingsurface 210 by a certain distance, thereby preventing the liquid level of the leakage liquid in theliquid storage groove 241 and theair guiding cavity 230 from being flush with thefree end surface 223, to prevent the leakage liquid from flowing out of theentire atomizer 10 by entering theair intake channel 500 through theoutlet port 510, thereby preventing theatomizer 10 from leaking. - For the leakage liquid dropping from the
inlet port 611, in the case that the dropping trajectory of the leakage liquid is a straight line extending in the vertical direction, since theinlet port 611 and theoutlet port 510 are completely misaligned, it is obvious that the leakage liquid will directly fall into theliquid storage groove 241. When the leakage liquid deviates from the straight dropping trajectory to drop floatingly, since the lower protrudingportion 340 is clamped between the two protrudingposts 220, and theinlet port 611 is located below theoutlet port 510, the protrudingposts 220 will block the leakage liquid, so that the leakage liquid that drops floatingly cannot enter theoutlet port 510 and flows into theliquid storage groove 241 along the outer surface of the protrudingpost 220, which finally prevents the leakage liquid that drops floatingly from entering theintake channel 500 via theoutlet port 510 and causing leakage. - Therefore, a part of the leakage liquid drops into the
liquid storage groove 241 through theoutlet port 510 from thefirst air channel 610, and theliquid storage groove 241 stores the part of the leakage liquid to prevent leakage. In addition, since theupper surface 310 of the sealingmember 300 is recessed to form thesunken groove 311, another part of the leakage liquid will not be able to drop into thefirst air channel 610, and this part of the leakage liquid will drop directly into thesunken groove 311, so that thesunken groove 311 stores this part of the leakage liquid. In addition, theupper end surface 331 of the upper protrudingportion 330 is located above theupper surface 310, so that the guidingoutlet 612 on theupper end surface 331 is higher than theupper surface 310 by a certain distance, thereby preventing the liquid level of the leakage liquid in thesunken groove 311 from being flush with theupper end surface 331 to prevent the leakage liquid from dropping into theliquid storage groove 241 through thefirst air channel 610 via the guidingoutlet 612. In this way, the leakage liquid stored in theliquid storage groove 241 and theair guiding cavity 230 will not be too much, so as to prevent the liquid level of the leakage liquid from being flush with thefree end surface 223 due to excessive leakage liquid, and finally prevent the leakage occurring when the leakage liquid enters theair intake channel 500 from theoutlet port 510. Therefore, a part of the leakage liquid is stored in thesunken groove 311 on the sealingmember 300, and theliquid storage groove 241 will not store all the leakage liquid, thereby greatly reducing the storage burden of theliquid storage groove 241 for the leakage liquid, and further improving the anti-leakage capability of theatomizer 10. - Referring to
FIGS. 10 and 11 , the present invention further provides anelectronic atomizing device 20. Theelectronic atomizing device 20 includes apower supply 30 and the above-mentionedatomizer 10. Theatomizer 10 is detachably connected to thepower supply 30. Since theatomizer 10 has a good anti-leakage capability, on the one hand, waste of liquid caused by leakage can be avoided, on the other hand, it is possible to prevent the leakage liquid from entering the inside of thepower supply 30 to erode the battery and electronic components, thereby improving the service life of theelectronic atomizing device 20. - The technical features of the above described embodiments can be combined arbitrarily. To simplify the description, not all possible combinations of the technical features in the above embodiments are described. However, all of the combinations of these technical features should be considered as being fallen within the scope of the present application, as long as such combinations do not contradict with each other.
