[0024] For a better understanding of the technical features, objects and effects of the present invention, the embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0025] Refer to FIG. 1 and FIG. 2, this application provides an atomizing core 100, the atomizing core 100 comprises a porous body 10 and a heating element 20, the material of the porous body 10 can be porous ceramic, the porous ceramic has good liquid-transferring performance.

[0026] The porous body 10 has an ability of adsorbing the substrate, then the heating element 20 heats the substrate to form aerosol. The porous body 10 defines an atomizing chamber 11 longitudinally penetrating the porous body 10 along the longitudinal direction of the atomizing core 100, and the heating element 20 is positioned within the atomizing chamber 11, the porous body 10 has a first end 12 adjacent to an inhalation end and a second end 13 opposite to the first end 12, wherein the first end 12 and the second end 13 are respectively provided with a limiting member 30 radially protruding from the porous body 10, the region between the limiting member 30 at the first end 12 and the limiting member 30 at the second end 13 defines an installation position 14 for positioning an oil-conducting cotton 322a.

[0027] In the atomizing core 100 provided by the present application, the opposite ends of the porous body 10 radially protrude with limiting members 30 (the limiting members 30 extend radially beyond the surface of the porous body 10), forming enlarged diameter ends at both ends of the porous body 10. These enlarged diameter ends define a zone of the installation position 14 for the oil-conducting cotton 322a.

[0028] By adsorbing condensate within this zone, the oil-conducting cotton 322a structurally blocks axial backflow of condensate along the porous body 10, preventing core components (such as sensors and processors) in the atomizing device from failure due to liquid erosion.

[0029] The limiting member 30 has various way to arrange, in an embodiment, the limiting member 30 has a flange 31, the flange 31 circumferentially surrounds the porous body 10, as shown in FIGS. 1 and 2. The flange 31 connected to the outer sidewall of the porous body 10, the flanges 31 at both ends of the porous body 10 jointly define an installation zone with the outer sidewall, structurally preventing misalignment during oil-conducting cotton assembly.

[0030] After assembly finished, assuming the oil-conducting cotton attempts to move longitudinally along the atomizing core 100, the flanges 31 at both ends exert a supporting reaction force to block such movement, thereby avoiding cotton detachment or edge curling.

[0031] In an embodiment, the limiting member 30 is protrusions 32, a plurality of protrusions 32 are arranged at intervals on the outer periphery of the porous body 10, as shown in FIG. 3. Similarly, the protrusions 32 at both ends of the porous body 10 and the outer sidewall of the porous body 10 define an installation position for the oil-conducting cotton 322a (as shown in FIG. 6), which can prevent misalignment during the assembly of the oil-conducting cotton 322a. After the oil-conducting cotton 322a is assembled, the protrusions 32 provide a supporting force to the oil-conducting cotton 322a to prevent it from moving longitudinally along the atomizing core 100, thereby avoiding the oil-conducting cotton 322a from detachment or edge curling.

[0032] In an embodiment, there is one protrusion 32, the protrusion 32 can support one side of the oil-conducting cotton 322a wrapped around the outer periphery of the porous body 10, and there is a risk of the opposite side of the oil-conducting cotton falling off.

[0033] In an embodiment, the number of the protrusions 32 is more than 8, since there are a relatively large number of protrusions 32 distributed on the outer periphery of the porous body 10, the spacing between two adjacent protrusions 32 is small, and the protrusions 32 are also thinner, which increases the manufacturing difficulty of the protrusions 32.

[0034] In an embodiment, the number of the protrusions 32 is set to be between 2 and 8, the protrusions 32 can not only limit the movement of the oil-conducting cotton 322a but also facilitate the manufacturing of itself. Specifically, the number of the protrusions 32 can be 2, 3, 4, 5, 6, 7, 8, etc., and no specific limitation is made here.

[0035] In an embodiment, the protrusion 31 is provided with a plurality of air intake notches 311, as shown in FIG. 1, the plurality of air intake notches 311 are arranged at intervals on the outer circumference of the porous body 10. External air can be introduced into and communicate with the oil-conducting cotton 322a via the air intake notch 311, and the oil-conducting cotton 322a is configured to be communication with oil chamber, allowing the external air to be introduced into the oil chamber via the air intake notches 311 to balance the gas pressure inside and outside the oil chamber, thereby ensuring smooth oil supply from the oil chamber.

[0036] Refer to FIG. 1 and FIG. 2, in one embodiment, the first end 12 of the porous body 10 is connected with a liquid storage wall 40, the liquid storage wall 40 extends in the direction away from the second end 13, and the projection of the liquid storage wall 40 on the horizontal plane is located within the projection of the limiting member 30 on the horizontal plane. As shown in FIG. 5, when the atomizing core 100 is mounted into the air passageway tube 313, the outer surface of the liquid storage wall 40, the inner surface of the air passageway tube 313, and the limiting member 30 disposed at the first end 12 are incorporated to define a collection chamber 41, the collection chamber 41 is used for storing and recycling the condensate, splashed droplets, or excess atomized liquid. The recycled liquid can be absorbed by the oil-conducting cotton 322a, thus preventing the liquid from flowing back into the atomizing chamber 11 and causing hole blockage.

[0037] In an embodiment, the outer projection of the liquid storage wall 40 on the horizontal plane is located within the outer projection of the porous body 10 on the horizontal plane, increasing the distance between the outer surface of the liquid storage wall 40 and the inner surface of the air passageway tube 313, and expanding the storage capacity of the collection chamber 41. As a result, more condensate can be stored, preventing the condensate from flowing back into the atomizing chamber 11 and causing hole blockage.

[0038] In one embodiment, the cross-sectional area of the atomizing chamber 11 within the range of the second end 13 gradually increases in the direction away from the first end 12, as shown in FIG. 2. The aperture of the atomization chamber 11 gradually expands at the second end 13. The inner wall of the atomizing chamber 11 can guide the excess substrate to flow away along the inner wall, preventing the excess substrate from accumulating in the atomization chamber 11 and causing hole blockage.

[0039] In one embodiment, the intersection line between the inner wall of the atomizing chamber 11 within the range of the second end 13 and the plane along the longitudinal direction of the atomizing core 100 can be either a curve or an inclined straight line.

[0040] In one embodiment, the intersection line is an inclined straight line. That is, the inner wall of the atomizing chamber 11 within the range of the second end 13 is inclined, and the angle between the inner wall and the horizontal plane can be between 60° and 85°. Tests have found that if the angle is greater than 85°, the inner wall of the atomizing chamber 11 within the range of the second end 13 is almost vertical, the increase in the aperture of the atomizing chamber 11 is minimal, and the inner wall of the atomizing chamber 11 hard to guide the excess substrate.

[0041] In one embodiment, the angle is less than 60°, the thickness of the side-wall of the atomizing chamber 11 within the range of the second end 13 is significantly reduced, resulting in insufficient strength of the porous body 10 at the second end 13, and it is prone to being crushed during the assembly process. When the angle between the inner wall of the atomizing chamber 11 within the range of the second end 13 and the horizontal plane is between 60° and 85°, the inner wall can guide the excess substrate to prevent hole blockage and also ensure the strength of the porous body 10 at the second end 13. Specifically, the angle between the inner wall of the atomizing chamber 11 within the range of the second end 13 and the horizontal plane can be 60°, 65°, 70°, 75°, 80°, 85°, etc.

[0042] Refer to FIG. 4 and FIG. 5, present application provides an atomizing device 300, the atomizing 300 comprises oil chamber 310, atomizing core 100 (as described above), base 330, mouthpiece 350, battery 360, outer housing 370 and bottom cover 380. An end of oil storage chamber 310 is provided with sealing member 320, the opposite end of the oil storage chamber 310 is connected to a base 330, the sensor 340 is assembled into the base 330, and the sensor 340 controls the atomizing device 300 to operate by detecting the airflow change. The oil storage chamber 310, the base 330, and the battery 360 are arranged in the outer housing 370, the end of the outer housing 370 adjacent to the oil storage chamber 310 is connected to a mouthpiece 350, and the opposite end of the housing 370 is provided with a bottom cover 380.

[0043] In one embodiment, the air passageway tube 313 is arranged into the oil storage chamber 310. The air passageway tube 313, the atomizing core 100, and the atomizing chamber 11 are in communication. The oil storage chamber has a storage container 314, and the storage container 314 is used to store the substrate. An oil-transferring cotton 50 is mounted between the two limiting members 30. The substrate flows to the porous body 10 via the oil-transferring cotton 50, and then the heating element 20 heats the substrate to form aerosol.

[0044] The liquid storage wall 40, the air passageway tube 313, and the limiting member 30 disposed at the first end portion 12 are incorporated to define a liquid collection chamber 41, the liquid collection chamber 41 is used for storing and recycling the condensate, splashed droplets, or excess atomized liquid. The recycled liquid can be absorbed by the oil-conducting cotton 322a, thus preventing the liquid from flowing back into the atomizing chamber 11 and causing hole blockage.

[0045] The atomizing core 100 provided by the present application has at least the following beneficial effects:

[0046] 1. In the atomizing core 100 provided by the present application, the two opposite ends of the porous body 10 has limiting members 30 respectively, so that to form increasing ends on the porous body 10, the increasing ends define an installation position to install the oil-transferring cotton,

[0047] 2. The number of the protrusions 32 is set to be between 2 and 8, the protrusions 32 can not only limit the movement of the oil-conducting cotton 322a but also facilitate the manufacturing of itself.

[0048] 3. The protrusion 31 has a plurality of air intake notches 311, allowing the external air to be introduced into the oil chamber via the air intake notches 311 to balance the gas pressure inside and outside the oil chamber, thereby ensuring smooth oil supply from the oil chamber.

[0049] 4. The liquid storage wall 40, the air passageway tube 313, and the limiting member 30 disposed at the first end portion 12 are incorporated to define a liquid collection chamber 41, the liquid collection chamber 41 is used for storing and recycling the condensate, splashed droplets, or excess atomized liquid. The recycled liquid can be absorbed by the oil-conducting cotton 322a, thus preventing the liquid from flowing back into the atomizing chamber 11 and causing hole blockage.

[0050] 5. the cross-sectional area of the atomizing chamber 11 within the range of the second end 13 gradually increases in the direction away from the first end 12, The inner wall of the atomizing chamber 11 can guide the excess substrate to flow away along the inner wall, preventing the excess substrate from accumulating in the atomization chamber 11 and causing hole blockage.

[0051] 6. the angle between the inner wall and the horizontal plane can be between 60° and 85°, the inner wall can guide the excess substrate to prevent hole blockage and also ensure the strength of the porous body 10 at the second end 13.

[0052] Refer to FIG. 6-8, the present invention provides an atomizing device 300a. The atomizing device 300a comprises an oil storage chamber 310a, an atomizing core 320a, a mouthpiece 330a, and a sealing member 100a. The two opposite ends of the sealing member 100a are connected to the oil storage chamber 310a and the mouthpiece 330a respectively, and the sealing member 100a is used to seal the oil storage chamber 310a and the mouthpiece 330a. The atomizing core 320a is arranged in the oil storage chamber 310a, and an end of the atomizing core 320a is inserted into the sealing member 100a. The atomizing core 320a and mouthpiece 330a are in communication. The oil storage chamber 310a is used to store the substrate. The substrate flows to the atomizing core 320a, and then the atomizing core 320a heats the substrate to form aerosol.

[0053] The atomizing device 300a may further include a sealing base 340a, a sensor 350a, a battery 360a, a bottom cover 370a, and an outer housing 380a. The bottom cover 370a is connected to the end of the outer housing 380a away from the mouthpiece 330a. The battery 360a, the sealing base 340a, the oil storage chamber 310a, and the sealing member 100a are sequentially assembled on the bottom cover 370a. One end of the atomizing core 320a is mounted on the sealing base 340a. The sensor 350a is installed inside the sealing base 340a. The sensor 350a controls the operating state of the atomizing device 300a by detecting the suction action at the end of the mouthpiece 330a. When the user is inhaling, the sensor 350a causes the atomizing core 320a to be connected to the battery 360a, and the atomizing core 320a heats the substrate to generate aerosol. When the inhalation stops, the sensor 350a controls the atomizing core 320a to be disconnected from the battery 360a, and the atomizing core 320a stops heating.

[0054] The outer housing 380a can be made of metal or plastic, while the mouthpiece 330a and the oil cup 310a can be made of plastic. The sealing member 100a and the sealing base 340a can be made of silicone. Silicone has a certain degree of elasticity. When the sealing member 100a and the sealing base 340a are assembled into the atomizing device 300a, they are deformed under compression. The sealing member 100a has an interference fit with the oil storage chamber 310a and the mouthpiece 330a to seal the oil storage chamber 310a and the mouthpiece 330a. The sealing base 340a has an interference fit with the oil storage chamber 310a to seal the end of the oil storage chamber 310a away from the mouthpiece. As a result, the atomizing device 300a has good air-tightness, which can increase the change of negative pressure during inhalation.

[0055] Refer to FIGS. 8 to 13, the atomizing core 320a comprises atomizing tube 321a, oil-transferring cotton 322a. The atomizing tube 321a is made of metal, and the oil-transferring cotton is made of plant fiber. One end of the atomizing tube 321a is inserted into the sealing member 100a; the atomizing tube 321a and the mouthpiece 330a are in communication, the sidewall of atomizing tube 321a is provided with oil-transferring hole 311b, the substrate in the oil storage chamber 310a flows into the oil-transferring cotton 322a via the oil-transferring hole 311b, and the heating element 323a heats the substrate adsorbed by the oil-transferring cotton 322a to form aerosol, the aerosol flows to the mouthpiece 330a via the atomizing tube 321a.

[0056] As the aerosol flows away from the atomizing core 320a toward the mouthpiece 330a, the temperature of the aerosol decreases, causing part of the aerosol to condense and liquefy into condensate. If the condensate flows back along the atomizing tube 321a, it may cause some components in the atomizing device 300a to fail. Additionally, the mixing of condensate into the aerosol will make the aerosol taste bad.

[0057] To prevent condensate from flowing back along the atomizing tube 321a, the present application provides a sealing member 100a. Refer to FIG. 9, the sealing member 100a is disposed between the oil storage chamber 310a and the mouthpiece 330a, and is used to seal the oil storage chamber. One end of the sealing member 100a adjacent to the mouthpiece 330a is provided with a plurality of spaced protrusions 110a. The protrusions 110a extend toward the end where the mouthpiece 330a is located. Each protrusion 110a and its adjacent protrusions 110a collectively form condensate adsorption gaps 111a, which are used to adsorb condensate. Thereby prevents the condensate from flowing back and causing failure of some components in the atomizing device 300a.

[0058] Condensate may form and accumulate on the inner wall of the atomizing tube 321a of the atomizing device 300a. As the aerosol flows away from the atomizing core 320a towards the mouthpiece 330a, its temperature drops. The closer it gets to the mouthpiece 330a, the higher the probability of condensate formation. By arranging the sealing member 100a between the oil cup 310a and the mouthpiece 330a and having the protrusions 110a extend towards the end where the mouthpiece 330a is located, it can be ensured that the condensate formed at the mouthpiece 330a is adsorbed by the condensate adsorption gaps 111a. When the atomizing device 300a is not in use, the condensate in the condensate adsorption gaps 111a can evaporate naturally, making it difficult for the condensate to flow downward along the atomizing tube 321a and accumulate inside the atomizing device 300a. As a result, it eliminates the possibility of some components in the atomizing device 300a, such as the sensor 350a, failing due to the accumulation of condensate.

[0059] Refer to FIG. 11, the sealing member 100a is provided with aperture 140a, as shown in FIG. 9, the atomizing tube 321a is inserted into the aperture 140a. As said in above embodiments; the protrusions 110a are arranged circumferentially around the air passage hole 140a, thus forming a plurality of circumferentially spaced condensate adsorption gaps 111a. The circular arrangement of the condensate adsorption gaps 111a ensure that the outer periphery of the flowing aerosol is evenly distributed with condensate adsorption gaps 111a, increasing the contact area between the condensate adsorption gaps 111a and the flowing aerosol, thereby enabling better adsorption of the condensate.

[0060] In some embodiments, refer to FIG. 11, the distance between two adjacent protrusions 110a is 0.4 mm to 0.5 mm. Experiments have found that if the distance between two adjacent protrusions 110a exceeds 0.5 mm, the relatively large spacing makes it difficult to generate capillary action on the condensate, and the condensate adsorption gaps 111a cannot adsorb the condensate. Conversely, if the distance between two adjacent protrusions 110a is less than 0.4 mm, it will increase the difficulty of processing the protrusions 110a and raise the manufacturing cost of the sealing member 100a. When the distance between two adjacent protrusions 110a is within the range of 0.4 mm to 0.5 mm, it not only effectively adsorbs the condensate but also facilitates the processing of the protrusions 110a. Specifically, the distance between two adjacent protrusions 110a can be 0.4 mm, 0.42 mm, 0.45 mm, 0.48 mm, 0.5 mm, etc., without specific limitations.

[0061] Assuming that the protrusions 110a extend too high toward the mouthpiece 330a, making the protrusions slender shape, the free end of each elongated protrusion 110a (which is close to the mouthpiece 330a) is susceptible to bending due to the soft nature of the silicone material. This bending causes the ends of two adjacent protrusions 110a to stick together, reducing the spacing between them and rendering the condensate adsorption gaps 111a ineffective for condensate adsorption. Conversely, if the height of the protrusions 110a is too low, the adsorption of condensate in the aerosol will be incomplete, leaving some condensate mixed in the aerosol and making the aerosol taste bad.

[0062] In some embodiments, the height of the protrusions 110a is set between 4.0 mm and 5.0 mm. Within this range, the protrusions 110a can effectively adsorb condensate while ensuring that their free ends do not bend, maintaining the functionality of the adsorption gaps. Specifically, the height of the protrusions 110a can be 4.0 mm, 4.2 mm, 4.5 mm, 4.8 mm, 5.0 mm, etc., without specific restrictions.

[0063] In one embodiment, a plurality of the protrusions 110a are parallel to each other, and each protrusion 110a has a same size and shape, the number of the protrusions 110a is 8 to 16, and the protrusions are evenly spaced to facilitate manufacturing, specifically, the number of the protrusions 110a can be 8, 10, 12, 14, or 16.

[0064] When the condensate adsorption gaps 111a absorb a large amount of condensate, the condensate may overflow and spread toward the outer periphery of the sealing member 100a. To prevent such overflow and spread, in one embodiment, a baffle 120a is connected to the end of the sealing member 100a adjacent to the mouthpiece 330a. As shown in FIG. 10, the baffle 120a surrounds the outer periphery of the plurality of protrusions 110a and restricts the condensate from overflowing to the outer periphery of the sealing member 100a.

[0065] The protrusions 110a can be connected to the inner wall of the baffle 120a, allowing the baffle 120a to be integrally processed with the protrusions 110a. The baffle 120a connects the roots of the plurality of protrusions 110a into a single unit, reducing the length of the free ends of the protrusions 110a and preventing the protrusions 110a from bending.

[0066] In one embodiment, the ratio of the height of the baffle 120a to that of the protrusions 110a is 0.4 to 0.6. The recovered condensate accumulates at the bottom of the condensate adsorption gaps 111a under the action of gravity. By setting the baffle 120a within the above-mentioned height range at the roots of the protrusions 110a, it is sufficient to prevent the condensate from overflowing to the outer periphery of the sealing member 100a, thereby saving material usage. Specifically, the ratio of the height of the baffle 120a to that of the protrusions 110a can be 0.4, 0.45, 0.5, 0.55, 0.6, etc.

[0067] In one embodiment, to convenient refueling the atomizing device 300a in a different place, a refueling hole 130a is formed in the sealing member 100a, as shown in FIG. 10. Correspondingly, refer to FIGS. 8 and 14, a sealing post 331a is provided on the mouthpiece 330a, as shown in FIG. 8. When the mouthpiece 330a is connected to the sealing member 100a, the sealing post 331a is inserted into the refueling hole 130a. During refueling, the substrate can be added to the oil storage chamber 310a through the refueling hole 130a. After refueling is completed, inserting the sealing post 331a into the refueling hole 130a seals the hole. However, when pressing the sealing post 331a into the refueling hole 130a, the sealing post 331a compresses the air inside the oil storage chamber 310a, increasing the air pressure within the oil storage chamber 310a. This creates a risk that the compressed air may push the substrate in the oil storage chamber 310a to leak outward.

[0068] Refer to FIG. 11, to overcome substrate leakage caused when the sealing post 331a is pressed into the refueling hole 130a, in one embodiment, sealing ribs 131a are provided on the inner wall of the refueling hole 130a, as shown in FIGS. 9 and 10. The sealing ribs 131a are annularly arranged and extend inward into the refueling hole 130a. When the sealing post 331a is pressed into the refueling hole 130a, the outer wall of the sealing post 331a only comes into contact with the sealing ribs 131a, forming a localized annular surface contact. This reduces the contact area between the sealing post 331a and the inner wall of the refueling hole 130a, thereby decreasing friction. Compared to direct contact between the sealing post 331a and the inner wall of the refueling hole 130a, this design allows partial air inside the oil storage chamber 310a to be released through the refueling hole 130a, reducing the air pressure within the oil storage chamber 310a and preventing substrate leakage during the insertion of the sealing post 331a.

[0069] After refueling is completed, the mouthpiece 330a is connected to the sealing member 100a, with the sealing post 331a on the mouthpiece 330a inserted into the refueling hole 130a. The sealing post 331a and the sealing ribs 131a cooperate to seal the oil storage chamber 310a.

[0070] In one embodiment, two baffles 120a are provided and arranged opposite to each other. Correspondingly, the number of the refueling holes 130a is also two. The refueling holes 130a and the baffles 120a are arranged at intervals around the outer periphery of the plurality of protrusions 110a. When the mouthpiece 330a is connected to the sealing member 100a, the sealing post 331a is inserted into the refueling hole 130a located between the two baffles 120a.

[0071] In one embodiment, the side-wall of the sealing post 331a can enclose with the baffles 120a (not shown in Figures) to prevent the condensate from overflowing to the outer periphery of the sealing member 100a.

[0072] The sealing member 100a provided by the present application has at least the following beneficial effects:

[0073] 1. The end of the sealing member 100a adjacent to the mouthpiece is provided with a plurality of spaced protrusions 110a. Each protrusion 110a can form a condensate adsorption gap 111a with its adjacent protrusions 110a. The condensate adsorption gap 111a is able to trap the condensate, thereby preventing the condensate from flowing back along the air passage and improving the taste of the aerosol.

[0074] 2. A plurality of protrusions 110a are arranged circumferentially around the air passage hole 140a, thereby increasing the contact area between the condensate adsorption gaps 111a and the flowing aerosol, enabling more effective adsorption of the condensate.

[0075] 3. The distance between two adjacent protrusions 110a is between 0.4 mm and 0.5 mm. This allows for good adsorption of the condensate and facilitates the processing of the protrusions 110a.

[0076] 4. The height of the protrusions 110a is 4.0 mm to 5.0 mm. This range not only enables sufficient adsorption of the condensate but also ensures that the free ends of the protrusions 110a do not bend, thus preventing them from losing their ability to adsorb the condensate.

[0077] 5. One end of the sealing member 100a adjacent to the mouthpiece 330a is connected to a baffle 120a. The baffle 120a not only restricts the condensate from overflowing to the outer periphery of the sealing member 100a but also reduces the length of the free ends of the protrusions 110a, preventing the protrusions 110a from bending.

[0078] 6. Sealing ribs 131a are provided on the inner wall of the refueling hole 130a, which reduces the contact area between the sealing post 331a and the inner wall of the refueling hole 130a. As a result, the friction between the sealing post 331a and the inner wall of the refueling hole 130a can be reduced, preventing the substrate from leaking when the sealing post 331a is pressed into the refueling hole 130a.

[0079] Refer to FIG. 12 to FIG. 14, one embodiment of present invention provides an atomizing device 100b, the atomizing device 100b comprises a mouthpiece 10b, oil storage chamber 20b, atomizing core 30b and base 40b, wherein one end of oil storage chamber 20b is connected to the base 40b, the opposite end of the oil storage chamber 20b is connected to the mouthpiece 10b; the atomizing core 30b is disposed in the oil chamber 20b, and the base 40b is equipped with a senor 41b.

[0080] In one embodiment, the base 40 is made of silicone, silicone has good elasticity, and the connection between the base 40b and the oil chamber 20b can undergo elastic deformation, which helps improve the sealing performance between the oil chamber 20b and the base 40b.

[0081] In one embodiment, the oil storage chamber 20b is used to store liquid substrate, which can flows into the atomizing core 30b. The atomizing core 30b heats the substrate to generate aerosol. The atomizing device 100b is provided with independent atomizing passageway 50b and controlling passage 60b. The atomizing passageway 50b connects the base 40b, the atomizing core 30b, and the mouthpiece 10b, external air is allowed to enter the atomizing core 30b through the atomizing passage 50b. The controlling passage 60b is in communication with the mouthpiece 10b and the sensor 41b. When a user inhales through the mouthpiece 10b, the sensor 41b will detect the changes of airflow within the control air passage 60b (e.g. pressure change), thereby controlling the operation state of the atomizing device 100b. A condensate collection chamber 61b is provided the controlling passageway 60b, where condensate generated in the controlling passageway 60b can converge into the condensate chamber 61b, and preventing the condensate from flowing toward the senor 41b. In addition, the size of the condensate recovery space 61b can be set as needed.

[0082] The atomizing device 100b provided in this application is equipped with independent atomizing passageway 50b and controlling passageway 60b. The senor 41b is installed on the controlling passageway 60b, which avoids condensate generated in the atomizing passageway 50b from flowing back and invading the sensor 41b. Furthermore, a condensate collection chamber 61b is provided on the controlling passageway 60b, preventing condensate generated in the controlling passageway 60b from flowing toward the sensor 41b. This avoids the invasion of condensate into the sensor 41b of the atomizing device 100b, thereby preventing the sensor 41b in the atomizing device 100b from failing due to condensate backflow.

[0083] In one embodiment, the atomizing device further comprises controlling assembly 70b, battery assembly 80b and outer housing 90b, battery assembly 80b, base 40b and partial oil storage chamber 20b are disposed in the outer housing 90b. The battery assembly 80b is configured to provide operating voltage.

[0084] The controlling passageway 60b may comprises a first branch controlling passageway 62b and a second branch controlling passageway 63b that extend longitudinally along the atomizing device 100b and are interconnected. The condensate collection chamber 61b is provided at the junction of the first branch controlling passageway 62b and the second branch controlling passageway 63b. The opposite ends of the first branch controlling passageway 62b respectively connect to the mouthpiece 10b and the condensate collection chamber 61b, while the opposite ends of the second branch controlling passageway 63b respectively connect to the sensor 41b and the condensate collection chamber 61b.

[0085] The projection on a horizontal plane of the end where the second branch controlling passageway 63b connects to the condensate collection chamber 61b lies outside the projection on a horizontal plane of the end where the first branch controlling passageway 62b connects to the condensate collection chamber 61b. This creates an offset design between the first branch controlling passageway 62b and the second branch controlling passageway 63b. Condensate formed within the first branch controlling passageway 62b will collect in the condensate recovery space 61b, preventing the condensate from entering the second branch controlling passageway 63b and causing reduced sensitivity or even failure of the sensor 41b.

[0086] Refer to FIG. 15, the atomizing passageway 50b may include a first branch atomizing passageway 51b and a second branch atomizing passageway 52b that are interconnected. Among them, the second branch atomizing passageway 52b extends from the base 40b toward the mouthpiece 10b. The end of the second branch atomizing passageway 52b adjacent to the base 40b is in communication with external air, so that allowing external air to enter the atomizing core 30b through the second branch atomizing passageway 52b. The first branch atomizing passageway 51b extends from the mouthpiece 10b toward the base 40b, and the end of the first branch atomizing passageway 51b adjacent to the base 40b is connected to the atomizing core 30b, thereby enabling external air to enter the atomizing core 30b.

[0087] The distance from the connection point of the first branch atomizing passageway 51b and the second branch atomizing passageway 52b to the mouthpiece 10b is shorter than the distance from the connection point of the first branch atomizing passageway 51b and the atomizing core 30b to the mouthpiece 10b. With this configuration, even if the substrate leaks, the leaked substrate will be collected in the space formed between the bottom of the atomizing core 30b and the base 40b, thereby restricting the substrate from leaking to the outside of the base 40b.

[0088] The atomizing passageway 50b and the controlling passageway 60b are independently arranged, thereby the airflow will not collide during the air is taken in. So that the inhalation is smoother without plosive sound.

[0089] The mouthpiece 10b is provided with a mouthpiece cover 11b. When the atomizing device 100b is not in operation state, the mouthpiece cover 11b covers the mouthpiece 10b, which can keep the mouthpiece 10b clean and hygienic.

[0090] Refer to FIG. 14, the oil storage chamber 20b comprises a side wall 21b, a partition 22b and an annular protrusion 23b. The side wall 21b and the partition 22b enclose a storage space 24b for storing the substrate. The partition 22b is connected to the inner wall of the side wall 21b. The annular protrusion 23b surrounds the outer periphery of the atomizing core 30b, and the annular protrusion 23b is connected to the side of the partition 22b away from the mouthpiece 10b.

[0091] An installation chamber 42b is provided on the base 40b. As shown in FIG. 15, the annular protrusion 23b is installed within the installation chamber 42b, where leaked substrate can be collected, preventing the substrate from leaking to the outside of the base 40b.

[0092] As shown in FIG. 12 to FIG. 14, the injunction of the oil storage chamber 20b and the mouthpiece 10b is provided with an upper sealing body 25b used to seal the storage space 24b. The upper sealing body 25b can be made of silicone to improving the sealing performance, thereby increasing the negative pressure change.

[0093] In one embodiment, the atomizing core 30b comprises an atomizing tube 31b, an oil transferring cotton 32b, a ceramic body 33b, and a heating wire 34b. The atomizing tube 31b is installed on the annular protrusion 23b. The oil transferring cotton 32b is housed inside the atomizing tube 31b and is in contact with the inner wall of the atomizing tube 31b. The oil transferring cotton 32b wraps around the ceramic body 33b, and the heating wire 34b is arranged inside the ceramic body 33b.

[0094] The atomizing tube 31b is provided with an oil passage hole 311b. The substrate is adsorbed through the oil passage hole 311b by the oil-conducting cotton 32b to the ceramic body 33b, and the heating wire 34b heats the substrate to generate aerosol.

[0095] In one embodiment, the controlling assembly 70b comprises a circuit board 71b and a button 72b that are correspondingly arranged. A mounting portion 26b is connected to the outer wall of the side wall 21b near the mouthpiece 10b, extending toward the housing 90b. The circuit board 71b is mounted onto the mounting portion 26b.

[0096] The button 72b passes through the housing 90b and is partially exposed outside the housing 90b. Pressing the button 72b triggers the circuit board 71b to control the atomizing device 100b. Specifically, pressing the button 72b can be configured to preheat the substrate via the atomizing core 30b, enhancing the fluidity of the substrate and improving atomizing efficiency. Alternatively, when the sensor 41b fails, pressing the button 72b enables manual activation of the atomizing core 30b, enhancing the stability of the atomizing device 100b.

[0097] The power supply assembly 80b may include a battery 81b, a charging circuit board 82b, and a charging interface 83b. The charging circuit board 82b and the charging interface 83b are sequentially arranged in the lower part of the base 40b, and the charging interface 83b is connected to the charging circuit board 82b. The battery 81b is installed in the space enclosed by the housing 90b, the oil chamber side wall 21b, and the mounting portion 26b.

[0098] By placing the battery 81b outside the side wall 21b, it facilitates the arrangement of a battery 81b with a larger capacity, making it suitable for the oil storage chamber 20b with a larger storage space 24b and improving the battery capacity of the atomizing device 100b.

When the oil storage chamber 20b is connected to the base 40b, the first branch controlling passageway 62b and the second branch controlling passageway 63b are connected through the condensate collection space 61b. By arranging the offset first branch controlling passageway 62b and second branch controlling passageway 63b on two separate components and forming the connection through assembly, the difficulty of processing the control air passage 60b is simplified.

That is, part of the outer periphery of the second branch controlling passageway 63b is closely attached to the inner wall of the condensate collection space 61b, as shown in FIG. 15. The second branch controlling passageway 63b and the condensate collection space 61b share partial side walls, with their side walls partially overlapping. Compared to accommodating one end of the second branch controlling passageway 63b entirely within the condensate collection space 61b, this design reduces the space occupied by the side wall thickness of the second branch controlling passageway 63b within the condensate collection space 61b, thereby increasing the capacity of the condensate collection space 61b and more effectively preventing condensate from flowing into the sensor 41b.

[0101] In one embodiment, the second branch atomizing passageway 52b is formed through the base 40b, which facilitates the processing of the second branch atomizing passageway 52b. An air intake groove 421b is provided on the inner wall of the mounting cavity 42b. The air intake groove 421b, the outer wall of the annular protrusion 23b, and the oil storage chamber partition 22b enclose to form the first branch atomizing passageway 51b. Forming the first branch atomizing passageway 51b in this enclosed way can avoid processing a bent and connected air passage inside the base 40b, which facilitates the processing of the first branch atomizing passageway 51b.

Additionally, a condensate collection space 61b is provided on the controlling passageway 60b, preventing condensate generated in the controlling passageway 60b from flowing toward the sensor 41b. This avoids the invasion of condensate into the sensor 41b of the atomizing device 100b, further improving the reliability of the atomizing device 100b.

[0104] 2. The projection on a horizontal plane of the end where the second branch controlling passageway 63b connects to the condensate collection space 61b lies outside the projection on a horizontal plane of the end where the first branch controlling passageway 62b connects to the condensate collection space 61b, preventing condensate from entering the second branch controlling passageway 63b and causing reduced sensitivity or even failure of the sensor 41b.

[0105] 3. The distance from the injunction of the first branch atomizing passageway 51b and the second branch atomizing passageway 52b to the mouthpiece 10b is shorter than the distance from the injunction of the first branch atomizing passageway 51b and the atomizing core 30b to the mouthpiece 10b, thereby restricting the substrate from leaking outside the base 40b.

[0106] 4. The first branch controlling passageway 62b and the second branch controlling passageway 63b are respectively formed on the side wall 21b and the base 40b.

[0107] 5. The condensate collection space 61b is shaped in a semi-enclosed manner surrounding one end of the second branch controlling passageway 63b. The second branch controlling passageway 63b and the condensate collection space 61b share partial side walls, reducing the space occupied by the side wall thickness of the second branch controlling passageway 63b within the condensate collection space 61b. This design increases the capacity of the condensate collection space 61b, enabling more effective prevention of condensate from invading the sensor 41b.

[0108] 6. The second branch atomizing passageway 52b is formed through the base 40b.
