[0040] like Figure 1 and Figure 2 As shown, an embodiment provides an atomizer 1000 , including an oil cup 110 , a base 200 , a bracket 300 and a first sealing member 410 .

[0041] The oil cup 110 is provided with a liquid storage cavity 1101 for containing an atomized substrate, and one end of the oil cup 110 is further provided with an opening structure 1102 communicating with the liquid storage cavity 1101. In some embodiments, the atomized substrate may be tobacco oil or the like.

[0042] The base 200 can be connected to one end of the oil cup 110 and can seal the opening 1102 of the oil cup 110. The bracket 300 is disposed on the side of the base 200 facing the liquid storage chamber 1101. Furthermore, the bracket 300 is provided with at least one liquid injection hole 301, which can communicate with the liquid storage chamber 1101. During assembly of the atomizer 1000, atomized substrate can be injected into the liquid storage chamber 1101 through the liquid injection hole 301.

[0043] like Figure 2 and Figure 3As shown, a first seal 410 can be disposed between the bracket 300 and the base 200. In some embodiments, the first seal 410 can include an integral seal body 411 and at least one sealing protrusion 412. The periphery of the seal body 411 can seal against the inner wall of the oil cup 110 facing the liquid storage chamber 1101. This allows for a clearance between the oil cup 110 and the base 200, isolating the oil cup 110 from the liquid storage chamber 1101, and sealing the opening structure 1102, thereby reducing leakage.

[0044] The sealing protrusion 412 protrudes from the side of the seal body 411 facing the bracket 300. At least one sealing protrusion 412 is inserted into at least one liquid injection hole 301 on the bracket 300 in a one-to-one correspondence. The circumference of the sealing protrusion 412 can seal against the inner wall of the liquid injection hole 301, thereby effectively sealing the liquid injection hole 301.

[0045] In the atomizer 1000 provided in the present application, the sealing of the liquid injection hole 301 and the sealing of the position of the opening structure 1102 of the oil cup 110 can be achieved by the first sealing member 410, thereby reducing the number of sealing members set in the atomizer 1000, thereby reducing the assembly steps of the atomizer 1000, improving the assembly efficiency of the atomizer 1000, and increasing the production capacity. At the same time, the material cost of the atomizer 1000 can also be reduced.

[0046] like Figure 1 As shown, the atomizer 1000 further includes a suction nozzle 130. In some embodiments, the atomizer 1000 may be a structure in which the oil cup 110 and the suction nozzle 130 are integrated. The suction nozzle 130 may be located at the end of the oil cup 110 away from the base 200, and the user may use the suction nozzle 130 for suction.

[0047] like Figure 2 、 Figure 4 and Figure 7 As shown, the atomizer 1000 further includes an atomizing core 510. In some embodiments, the bracket 300 may include an integral bracket body 310 and an extension portion 320. The bracket body 310 may abut against the inner wall of the oil cup 110 on its circumference, forming an interference fit. The extension portion 320 may protrude from the side of the bracket body 310 facing away from the first seal 410.

[0048] In some embodiments, an assembly cavity 302 may be defined in the extension portion 320. The assembly cavity 302 may extend to and penetrate the bracket body 310. Accordingly, the assembly cavity 302 may communicate with a side of the bracket 300 facing the first sealing member 410. The atomizer core 510 may be mounted in the assembly cavity 302, and the central axis of the atomizer core 510 may be coaxial with the central axis L of the atomizer 1000.

[0049] In some embodiments, the extension portion 320 is further provided with a liquid inlet 303 connecting the assembly cavity 302 and the liquid storage cavity 1101. During use, the aerosolized substrate in the liquid storage cavity 1101 can enter the liquid storage cavity 1101 through the liquid inlet 303 and be absorbed by the atomizer core 510. The atomizer core 510 then heats and atomizes the aerosolized substrate to generate an aerosol for the user to inhale.

[0050] like Figures 2 to 4 as well as Figure 7 As shown, the injection hole 301 can be opened on the bracket body 310, and the injection hole 301 can pass through the bracket body 310 along the axial direction of the atomizer 1000. The axial direction of the atomizer 1000 can refer to the extension direction of the central axis L.

[0051] In some embodiments, the support body 310 may be provided with two injection holes 301, which may be symmetrically arranged about the extension portion 320. When assembling the nebulizer 1000, the atomized matrix can be simultaneously injected into the liquid storage chamber 1101 through the two injection holes 301, thereby improving the injection efficiency of the atomized matrix and thus improving the assembly efficiency of the nebulizer 1000.

[0052] In some embodiments, the bracket body 310 may also be provided with three, four, or six injection holes 301. The multiple injection holes 301 may be uniformly or non-uniformly arranged around the circumference of the extension portion 320. When assembling the atomizer 1000, the atomized matrix can be injected into the liquid storage chamber 1101 through at least one of the injection holes 301. Of course, the atomized matrix can also be injected into the liquid storage chamber 1101 simultaneously through multiple injection holes 301 to improve the injection efficiency of the atomized matrix, thereby improving the assembly efficiency of the atomizer 1000 and increasing production capacity.

[0053] like Figures 2 to 4 as well as Figure 8 As shown, the number of sealing protrusions 412 can be equal to the number of injection holes 301. In some embodiments, the first sealing member 410 can include two sealing protrusions 412, which are inserted into the two injection holes 301 in a one-to-one correspondence to seal the two injection holes 301.

[0054] In some embodiments, the projection contours of the first seal 410 and the oil cup 110 on the base 200 are the same, that is, the first seal 410 basically completely covers the opening of the oil cup 110 facing one end of the base 200. This form of the first seal 410 improves the assembly efficiency on the one hand, and on the other hand, the oil cup 110 can be used to limit the assembly of the first seal 410.

[0055] It should be noted that, since the first sealing member 410 has a via hole corresponding to the connecting column 522 and a via hole corresponding to the air intake duct, the same profile mentioned in this embodiment refers to the circumferential edge profile of the first sealing member 410 .

[0056] In some embodiments, at least one first sealing flange 413 is provided protruding from the periphery of the sealing protrusion 412. The first sealing flange 413 may be provided around the periphery of the sealing protrusion 412, i.e., the first sealing flange 413 may be an annular structure. The side of the first sealing flange 413 facing away from the sealing protrusion 412 may abut against the inner wall of the liquid injection hole 301, forming an interference fit with the inner wall of the liquid injection hole 301. This improves the sealing effect of the liquid injection hole 301 and reduces the possibility of leakage.

[0057] In some embodiments, two first sealing flanges 413 may be provided protruding from the periphery of the sealing protrusion 412. The two first sealing flanges 413 may be arranged sequentially along the insertion direction of the sealing protrusion 412 into the liquid injection hole 301. This can extend the sealing path between the sealing protrusion 412 and the inner wall of the liquid injection hole 301, further improving the sealing effect and reducing the probability of leakage. The insertion direction of the sealing protrusion 412 may be parallel to the axial direction of the atomizer 1000.

[0058] In some embodiments, the first sealing flange 413 may be provided in one, three, or four numbers. When there are multiple first sealing flanges 413 , the multiple first sealing flanges 413 may be sequentially distributed along the insertion direction of the sealing protrusion 412 .

[0059] In some embodiments, the peripheral surface of the sealing protrusion 412 may directly abut against the inner wall of the liquid injection hole 301 and have an interference fit with the inner wall of the liquid injection hole 301 .

[0060] like Figures 2 to 4 as well as Figure 8 As shown, in some embodiments, at least one second sealing flange 414 is provided protruding from the circumference of the seal body 411. The second sealing flange 414 can be arranged around the circumference of the seal body 411, that is, the second sealing flange 414 can also be an annular structure. The side of the second sealing flange 414 facing away from the seal body 411 can abut against the inner wall of the oil cup 110, and the second sealing flange 414 can form an interference fit with the inner wall of the oil cup 110. This ensures a tight seal between the seal body 411 and the inner wall of the oil cup 110, improving the sealing effect.

[0061] In some embodiments, a second sealing flange 414 may be protruding from a peripheral side of the sealing body 411 .

[0062] In some embodiments, the seal body 411 may also be provided with a plurality of second sealing flanges 414, such as two, three, or five, protruding from its circumference. These plurality of second sealing flanges 414 may be sequentially distributed along the axial direction of the atomizer 1000. This can extend the sealing path between the seal body 411 and the inner wall of the oil cup 110, further reducing the likelihood of leakage.

[0063] In some embodiments, the peripheral surface of the sealing body 411 may also directly abut against the inner wall of the oil cup 110 and form an interference fit with the inner wall of the oil cup 110 .

[0064] like Figures 2 to 4 as well as Figure 9 As shown, in some embodiments, the sealing protrusion 412 further defines an insertion groove 415 on a side facing the sealing body 411. The insertion groove 415 may extend axially along the atomizer 1000 to the sealing body 411 and penetrate the sealing body 411. Accordingly, the insertion groove 415 may communicate with a side of the first sealing member 410 facing the base 200.

[0065] In some embodiments, the base 200 may include a base body 210 and at least one push portion 220. The base body 210 may be connected to the oil cup 110 via a snap-fit ​​connection, screw connection, or magnetic connection, and may seal the opening 1102 of the oil cup 110. The push portion 220 protrudes from the side of the base body 210 facing the first sealing member 410. The at least one push portion 220 may be inserted into the at least one insertion slot 415 in a one-to-one correspondence.

[0066] In some embodiments, the base 200 may include two pushing portions 220, which are inserted into the two insertion grooves 415 on the first sealing member 410 in a one-to-one correspondence. The end surface of the pushing portion 220 facing away from the end of the base body 210 may abut against the bottom of the insertion groove 415 opposite to the base 200.

[0067] When assembling the atomizer 1000, the first sealing member 410 can be placed over the side of the base 200 where the push portion 220 is located, with the push portion 220 inserted into the corresponding insertion groove 415. Subsequently, the base 200 and the first sealing member 410 can be inserted through the opening 1102 of the oil cup 110, with the sealing protrusion 412 inserted into the corresponding injection hole 301. The push portion 220 exerts a pushing force on the sealing protrusion 412, facilitating its smooth insertion into the injection hole 301.

[0068] In some embodiments, the sealing protrusion 412 can also be configured as a solid cylindrical structure. During assembly of the atomizer 1000, the first sealing member 410 can be first installed into the oil cup 110, and the sealing protrusion 412 can be directly inserted into the corresponding injection hole 301 on the bracket 300. Then, the base 200 can be connected to the oil cup 110.

[0069] In some embodiments, the end of the sealing protrusion 412 facing away from the sealing body 411 may be provided with a guide slope 4121. The guide slope 4121 may gradually slope away from the inner wall of the injection hole 301 from the end close to the sealing body 411 to the end away from the sealing body 411.

[0070] like Figure 2 、 Figure 4 、 Figure 8 and Figure 9 As shown, the atomizer 1000 further includes two conductive electrodes 520. One of the conductive electrodes 520 can be used as a positive electrode, and the other conductive electrode 520 can be used as a negative electrode.

[0071] In some embodiments, the conductive electrode 520 may include an integrated contact piece 521 and a connecting post 522. The contact piece 521 may be located at one end of the connecting post 522. The connecting post 522 may be sequentially inserted through the base body 210 and the sealing body 411, and inserted into the side of the bracket body 310 facing the first sealing member 410. Accordingly, the sealing body 411 may be provided with a first through-hole 4111 for the connecting post 522 to pass through, and the base body 210 may be provided with a third through-hole 211 for the connecting post 522 to pass through. The first through-hole 4111 may be coaxially opposed to and connected to the third through-hole 211. In embodiments, the connecting post 522 may be electrically connected to the atomizer core 510 via a structure such as a wire.

[0072] The contact piece 521 can be embedded in the side of the base body 210 facing away from the first sealing member 410, and the contact piece 521 can be exposed to the external environment. During use, when the atomizer 1000 is connected to the power supply structure of the atomizing device, the contact piece 521 can make contact and electrically connect with the power supply terminal of the power supply structure, so that the power supply structure can power the atomizer 1000.

[0073] like Figures 4 to 6 、 Figure 8 and Figure 9As shown, in some embodiments, the base body 210 further defines an air inlet hole 212. The air inlet hole 212 may extend through the base body 210 along the axial direction of the atomizer 1000. One end of the air inlet hole 212 may communicate with the external environment, while the other end of the air inlet hole 212 may communicate with a side of the base body 210 facing the first sealing member 410. In some embodiments, the base body 210 may define two air inlet holes 212, which may be symmetrically arranged about the central axis L of the atomizer 1000.

[0074] In some embodiments, the base body 210 may also be provided with one, three, or five air inlet holes 212. When there are multiple air inlet holes 212, the multiple air inlet holes 212 may be arranged around the central axis L of the atomizer 1000.

[0075] In some embodiments, the seal body 411 is further provided with a second through-hole 4112, which can penetrate the seal body 411 along the axial direction of the atomizer 1000. One end of the second through-hole 4112 can communicate with the air inlet 212. In some embodiments, the second through-hole 4112 and the air inlet 212 can be connected through the cavity between the base body 210 and the seal body 411. The other end of the second through-hole 4112, facing away from the air inlet 212, can be opposite to and communicate with the assembly cavity 302 on the bracket 300, thereby connecting the second through-hole 4112 to the atomization channel 5101 of the atomizer 1000. During use of the atomizer 1000, external air can enter the assembly cavity 302 of the bracket 300 through the air inlet 212 and the second through-hole 4112 in sequence, and then enter the atomization channel 5101 of the atomizer core 510.

[0076] In some embodiments, two second through holes 4112 may be defined in the sealing body 411 , and the two second through holes 4112 may be symmetrically disposed about the central axis L of the atomizer 1000 .

[0077] In some embodiments, the seal body 411 may further include one, three, or five second via holes 4112. When the seal body 411 includes multiple second via holes 4112, the multiple second via holes 4112 may be disposed around the central axis L.

[0078] In some embodiments, the second through hole 4112 may be offset from the air inlet 212 along a direction around the central axis L. That is, the projection of the inner wall of the second through hole 4112 on the base body 210 does not overlap or partially overlaps with the air inlet 212. This reduces the probability of condensate and leaked atomized matrix dripping directly into the air inlet 212 through the second through hole 4112 and leaking outward.

[0079] In some embodiments, the nebulizer 1000 further includes a liquid wicking member 610, which can be disposed on a side of the base body 210 facing the first sealing member 410. In some embodiments, a recessed groove 213 can be defined on the side of the base body 210 facing the first sealing member 410. The recessed groove 213 can be opposite and in communication with the second through-hole 4112, and the liquid wicking member 610 can be disposed in the recessed groove 213. During use, condensed liquid and leaked atomized matrix can enter the recessed groove 213 through the second through-hole 4112 and be absorbed by the liquid wicking member 610, thereby preventing the condensed liquid and leaked atomized matrix from further leaking outside the nebulizer 1000.

[0080] In some embodiments, the absorbent member 610 may be made of an oil storage material such as a cotton sheet or a sponge.

[0081] like Figures 4 to 6 As shown, the atomizer 1000 further includes an air pipe 120 having an air flow channel 1201 disposed therein. In an embodiment, the air pipe 120 may be disposed in the oil cup 110 , and the air flow channel 1201 within the air pipe 120 may be isolated from the liquid storage chamber 1101 .

[0082] In some embodiments, the end of the air supply pipe 120 facing the suction nozzle 130 can be integrally connected to the oil cup 110 and communicate with the suction nozzle 130. The end of the air supply pipe 120 facing away from the suction nozzle 130 can abut the end surface of the extension portion 320 facing away from the bracket body 310, and the air supply pipe 120 and the extension portion 320 are sealed. In addition, the end of the extension portion 320 away from the bracket body 310 is also provided with a fourth through hole 321 connected to the assembly cavity 302. The air flow channel 1201 and the atomization channel 5101 can be connected through the fourth through hole 321, and the air flow channel 1201, the fourth through hole 321 and the atomization channel 5101 can cooperate to form the air supply channel 620 in the atomizer 1000. The aerosol generated by the atomization core 510 can be transported to the suction nozzle 130 through the air supply channel 620 for the user to inhale.

[0083] In some embodiments, the nebulizer 1000 further includes a second sealing member 420, which can be configured to seal the gas delivery channel 620 when the nebulizer 1000 is not in use. In some embodiments, the second sealing member 420 can include a first handle 422 and a first plunger 421. The first handle 422 can be fixedly connected to one end of the first plunger 421 by integral connection or bonding.

[0084] The first plunger 421 can be sequentially inserted into the airflow channel 1201, the fourth through-hole 321, and the atomization channel 5101 (i.e., the gas delivery channel 620) from one end of the nozzle 130. The first grip 422 can be positioned on the side of the nozzle 130 facing away from the base 200, making it easily accessible to the user. To use the atomizer 1000, the user grasps the first grip 422 to pull the second sealing member 420, removing the first plunger 421 from the gas delivery channel 620.

[0085] In some embodiments, at least one third sealing flange 423 is further provided protruding from the circumference of the first plunger portion 421. The third sealing flange 423 may be provided around the circumference of the first plunger portion 421, i.e., the third sealing flange 423 has an annular structure. The side of the third sealing flange 423 facing away from the first plunger portion 421 may abut against the inner wall of the gas pipe 120 facing the airflow channel 1201. The third sealing flange 423 may also form an interference fit with the inner wall of the gas pipe 120, thereby sealing the gas flow channel 620.

[0086] In some embodiments, three third sealing flanges 423 may be protruding from the circumference of the first plunger portion 421. The three third sealing flanges 423 may be sequentially distributed along the axial direction of the atomizer 1000, and may be evenly or unevenly distributed. This can extend the sealing path of the gas delivery channel 620 and reduce the probability of gas leakage.

[0087] In some embodiments, the second sealing member 420 may be made of a flexible material such as silicone or rubber.

[0088] like Figures 4 to 6 As shown, the atomizer 1000 further includes a third sealing member 430. The third sealing member 430 may include a second handle portion 432 and a second plunger portion 431. The second handle portion 432 may be fixedly connected to one end of the second plunger portion 431 by means of an integral connection or adhesive bonding. The number of second plungers 431 provided may be equal to the number of air inlet holes 212 on the base 200, and each second plunger portion 431 may correspond one-to-one with each air inlet hole 212.

[0089] In some embodiments, the second plunger portion 431 can be inserted into the air inlet hole 212 and can be sealed with the inner wall of the air inlet hole 212 to seal the air inlet hole 212. In some embodiments, the peripheral surface of the second plunger portion 431 can be interference fit with the inner wall of the air inlet hole 212.

[0090] In some embodiments, a sealing flange may be provided protruding from the circumference of the second plunger portion 431. The sealing flange may be provided around the circumference of the second plunger portion 431. The side of the sealing flange facing away from the second plunger portion 431 may abut against the inner wall of the air inlet hole 212 and have an interference fit with the inner wall of the air inlet hole 212.

[0091] In this embodiment, the second handle 432 can be located on a side of the base body 210 facing away from the first sealing member 410 to facilitate user access and gripping. When the third sealing member 430 needs to be removed, the user can grasp the second handle 432 to pull the third sealing member 430, thereby removing the second plunger 431 from the air inlet 212.

[0092] In some embodiments, the third sealing member 430 may be made of a flexible material such as silicone or rubber.

[0093] When the atomizer 1000 is not in use, such as when being transported or carried outside, the first plunger portion 421 of the second sealing member 420 can be inserted through the nozzle 130 into the air delivery channel 620, and the second plunger portion 431 of the third sealing member 430 can be inserted into the air inlet 212. This seal ensures the interior of the atomizer 1000 is intact, preventing leakage of the atomized substrate in the liquid storage chamber 1101 due to pressure fluctuations or swaying. It also prevents dust and other particles from entering the atomizer 1000 through the air delivery channel 620 and air inlet 212, potentially causing contamination.

[0094] When the user needs to use the atomizer 1000 , the second sealing member 420 and the third sealing member 430 can be pulled out, so that the gas delivery channel 620 and the gas inlet 212 are both connected to the external environment.

[0095] The embodiments also provide an atomization device, including a power supply structure and an atomizer 1000 provided in the embodiments. The power supply structure can be connected to one end of the atomizer 1000 near the base 200 and can be electrically connected to the conductive electrode 520 in the atomizer 1000. Thus, the power supply structure can provide power to the atomizer 1000.
