Detailed Implementation

[0030] As shown in Figures 1 and 2, an atomizer 1000 is provided in this embodiment, including an oil cup 110, a base 200, a support 300, and a first sealing member 410. The oil cup 110 is provided with a liquid storage chamber 1101 for holding the atomizing matrix, and one end of the oil cup 110 is also provided with an opening structure 1102 communicating with the liquid storage chamber 1101. In some embodiments, the atomizing matrix may be e-liquid, etc.

[0031] In this embodiment, the base 200 can be connected to one end of the oil cup 110 and can close the opening structure 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 has at least one injection hole 301, which can communicate with the liquid storage chamber 1101. During the assembly of the atomizer 1000, the atomizing matrix can be injected into the liquid storage chamber 1101 through the injection hole 301.

[0032] As shown in Figures 2 and 3, the first seal 410 can be disposed between the bracket 300 and the base 200. In some embodiments, the first seal 410 may 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 cavity 1101. Thus, the assembly gap between the oil cup 110 and the base 200 can be eliminated, and the oil cup 1100 can be isolated from the liquid storage cavity 1101, i.e., the opening structure 1102 can be sealed, reducing the occurrence of leakage problems.

[0033] In this embodiment, a sealing protrusion 412 protrudes from the side of the sealing body 411 facing the bracket 300, and at least one sealing protrusion 412 is inserted into at least one injection hole 301 on the bracket 300. Furthermore, the periphery of the sealing protrusion 412 can seal against the inner wall of the injection hole 301. Thus, the injection hole 301 can be sealed.

[0034] In the atomizer 1000 provided in this application, the liquid injection hole 301 and the opening structure 1102 of the oil cup 110 can be sealed by the first sealing element 410. This reduces the number of sealing elements required in the atomizer 1000, thereby reducing the assembly steps, improving assembly efficiency, increasing production capacity, and also reducing material costs.

[0035] As shown in Figure 1, the atomizer 1000 also includes a mouthpiece 130. In some embodiments, the atomizer 1000 may be an integrated structure of the oil cup 110 and the mouthpiece 130. The mouthpiece 130 may be located at the end of the oil cup 110 away from the base 200, and the user can use the mouthpiece 130 for vaping.

[0036] As shown in Figures 2, 4, and 7, the atomizer 1000 also includes an atomizing core 510. In some embodiments, the support 300 may include an integral support body 310 and an extension 320. The periphery of the support body 310 may abut against the inner wall of the oil cup 110 and may be press-fitted. The extension 320 may protrude from the side of the support body 310 opposite to the first seal 410.

[0037] In some embodiments, an assembly cavity 302 may be provided in the extension 320. The assembly cavity 302 may extend to and penetrate the bracket body 310. Accordingly, the assembly cavity 302 may communicate with the side of the bracket 300 facing the first seal 410. The atomizing core 510 may be installed in the assembly cavity 302, and the central axis of the atomizing core 510 may be coaxial with the central axis L of the atomizer 1000.

[0038] In some embodiments, the periphery of the extension 320 is further provided with a liquid inlet 303 that connects the assembly cavity 302 and the liquid storage cavity 1101. During use, the atomizing matrix in the liquid storage cavity 1101 can enter the liquid storage cavity 1101 through the liquid inlet 303 and be absorbed by the atomizing core 510. The atomizing core 510 then heats and atomizes the atomizing matrix to generate an aerosol, which can be used by the user for suction.

[0039] As shown in Figures 2 to 4 and Figure 7, the injection hole 301 can be opened on the support body 310, and the injection hole 301 can penetrate the support 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.

[0040] In some embodiments, the support body 310 may have two injection holes 301, which may be symmetrically arranged about the extension 320. When assembling the atomizer 1000, the atomizing matrix can be injected into the liquid storage chamber 1101 simultaneously through the two injection holes 301, thereby improving the injection efficiency of the atomizing matrix and thus improving the assembly efficiency of the atomizer 1000.

[0041] In some embodiments, the support body 310 may also have three, four, or six injection holes 301. The injection holes 301 may be uniformly or non-uniformly arranged around the periphery of the extension 320. When assembling the atomizer 1000, the atomizing matrix can be injected into the liquid storage chamber 1101 through at least one injection hole 301. Alternatively, the atomizing matrix can be injected into the liquid storage chamber 1101 simultaneously through multiple injection holes 301, improving the injection efficiency of the atomizing matrix, thereby increasing the assembly efficiency of the atomizer 1000 and enhancing production capacity.

[0042] As shown in Figures 2 to 4 and Figure 8, the number of sealing protrusions 412 can be equal to the number of injection holes 301. In some embodiments, the first seal 410 may 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.

[0043] In some embodiments, the projections of the first seal 410 and the oil cup 110 on the base 200 have the same outline, that is, the first seal 410 basically completely covers the opening of the oil cup 110 facing the base 200. This type of first seal 410 improves assembly efficiency on the one hand, and the oil cup 110 can be used to limit the assembly of the first seal 410 on the other hand.

[0044] It should be noted that since the first sealing member 410 has a first through hole 4111 corresponding to the connecting post 522 and a second through hole 4112 corresponding to the air inlet 212, the same outline mentioned in this embodiment refers to the circumferential edge outline of the first sealing member 410.

[0045] In some embodiments, at least one first sealing flange 413 protrudes from the periphery of the sealing protrusion 412. The first sealing flange 413 may surround the periphery of the sealing protrusion 412, that is, the first sealing flange 413 may be annular. The side of the first sealing flange 413 opposite to the sealing protrusion 412 may abut against the inner wall of the injection hole 301 and be press-fitted with the inner wall of the injection hole 301. This improves the sealing effect of the injection hole 301 and reduces the probability of leakage.

[0046] In some embodiments, two first sealing flanges 413 may protrude from the periphery of the sealing protrusion 412, and the two first sealing flanges 413 may be arranged sequentially along the insertion direction of the sealing protrusion 412 into the injection hole 301. This extends the sealing path between the sealing protrusion 412 and the inner wall of the 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.

[0047] In some embodiments, the first sealing flange 413 may be provided in the form of one, three, or four, etc. When multiple first sealing flanges 413 are provided, the multiple first sealing flanges 413 may be distributed sequentially along the insertion direction of the sealing protrusion 412.

[0048] In some embodiments, the surface of the sealing protrusion 412 on the periphery can directly abut against the inner wall of the injection hole 301 and be interference-fitted with the inner wall of the injection hole 301.

[0049] As shown in Figures 2 to 4 and Figure 8, in some embodiments, at least one second sealing flange 414 protrudes from the periphery of the sealing body 411. The second sealing flange 414 may surround the periphery of the sealing body 411, that is, the second sealing flange 414 may also be annular. The side of the second sealing flange 414 facing away from the sealing body 411 may abut against the inner wall of the oil cup 110, and the second sealing flange 414 may be interference-fitted with the inner wall of the oil cup 110. Thus, a sealing fit can be achieved between the sealing body 411 and the inner wall of the oil cup 110, and the sealing effect can be improved.

[0050] In some embodiments, a second sealing flange 414 may be provided protruding from the periphery of the sealing body 411.

[0051] In some embodiments, two, three, or five or more second sealing flanges 414 may protrude from the periphery of the sealing body 411. These multiple second sealing flanges 414 may be sequentially distributed along the axial direction of the atomizer 1000. This extends the sealing path between the sealing body 411 and the inner wall of the oil cup 110, further reducing the probability of leakage.

[0052] In some embodiments, the surface of the sealing body 411 on its periphery may also directly abut against the inner wall of the oil cup 110 and be interference-fitted with the inner wall of the oil cup 110.

[0053] As shown in Figures 2 to 4 and Figure 9, in some embodiments, the sealing protrusion 412 has an insertion groove 415 on the side facing the sealing body 411. The insertion groove 415 can extend along the axial direction of the atomizer 1000 to the sealing body 411 and penetrate through the sealing body 411. Accordingly, the insertion groove 415 can communicate with the side of the first sealing member 410 facing the base 200.

[0054] In some embodiments, the base 200 may include a base body 210 and at least one pushing portion 220. The base body 210 may be connected to the oil cup 110 by means of snap-fit ​​connection, screw connection, or magnetic connection, and may close the opening structure 1102 of the oil cup 110. The pushing portion 220 protrudes from the side of the base body 210 facing the first sealing member 410. At least one pushing portion 220 may be inserted into at least one mating groove 415.

[0055] In some embodiments, the base 200 may include two pushing portions 220, which are inserted into two mating grooves 415 on the first seal 410 in a one-to-one correspondence. The end face of the pushing portion 220 facing away from the base body 210 can abut against the bottom of the groove in the mating groove 415 opposite to the base 200.

[0056] When assembling the atomizer 1000, the first sealing member 410 can be sleeved on the side of the base 200 where the pusher portion 220 is provided, and the pusher portion 220 can be inserted into the corresponding insertion groove 415. Subsequently, the base 200 and the first sealing member 410 can be inserted together through the opening structure 1102 of the oil cup 110, and the sealing protrusion 412 can be inserted into the corresponding liquid injection hole 301. The pusher portion 220 can apply a pushing action to the sealing protrusion 412, thereby facilitating the smooth insertion of the sealing protrusion 412 into the liquid injection hole 301.

[0057] In some embodiments, the sealing protrusion 412 may also be configured as a solid cylindrical structure. During the assembly of the atomizer 1000, the first seal 410 can be inserted into the oil cup 110 first, and the sealing protrusion 412 can be directly inserted into the liquid injection hole 301 at the opposite position on the bracket 300. Then, the base 200 is connected to the oil cup 110.

[0058] 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 near the sealing body 411 to the end away from the sealing body 411.

[0059] As shown in Figures 2, 4, 8, and 9, the atomizer 1000 also includes two conductive electrodes 520. One conductive electrode 520 can be used as a positive electrode, and the other conductive electrode 520 can be used as a negative electrode.

[0060] In some embodiments, the conductive electrode 520 may include an integral 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 passed 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. Correspondingly, the sealing body 411 may have a first through hole 4111 for the connecting post 522 to pass through, and the base body 210 may have a third through hole 211 for the connecting post 522 to pass through. The first through hole 4111 and the third through hole 211 may be coaxially opposite and communicate with each other. In embodiments, the connecting post 522 may be electrically connected to the atomizing core 510 through a structure such as a wire.

[0061] In some embodiments, the contact piece 521 may be embedded in the base body 210 on the side away from the first seal 410, and the contact piece 521 may be exposed relative to the external environment. During use, when the atomizer 1000 is connected to the power supply structure in the atomizing device, the contact piece 521 may make contact with the power supply terminal in the power supply structure, so that the power supply structure can supply power to the atomizer 1000.

[0062] As shown in Figures 4 to 6, 8, and 9, in some embodiments, the base body 210 is further provided with an air inlet 212. The air inlet 212 can penetrate the base body 210 along the axial direction of the atomizer 1000. One end of the air inlet 212 can communicate with the external environment, and the other end of the air inlet 212 can communicate with the side of the base body 210 facing the first seal 410. In some embodiments, the base body 210 can have two air inlets 212, and the two air inlets 212 can be symmetrically arranged about the central axis L of the atomizer 1000.

[0063] In some embodiments, the base body 210 may also have one, three, or five air inlets 212. When multiple air inlets 212 are provided, the multiple air inlets 212 may be arranged around the central axis L of the atomizer 1000.

[0064] In some embodiments, a second through hole 4112 is also provided on the sealing body 411, and the second through hole 4112 can penetrate the sealing 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 sealing body 411. The other end of the second through hole 4112 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 with the atomization channel 5101 of the atomizer 1000. During the use of the atomizer 1000, external gas 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 atomizing core 510.

[0065] In some embodiments, two second through holes 4112 may be provided on the sealing body 411, and the two second through holes 4112 may be symmetrically arranged about the central axis L of the atomizer 1000.

[0066] In some embodiments, one, three, or five equal numbers of second through holes 4112 may be provided on the sealing body 411. When multiple second through holes 4112 are provided on the sealing body 411, the multiple second through holes 4112 may be arranged around the periphery of the central shaft L.

[0067] In some embodiments, the second through-hole 4112 may be offset from the air inlet 212 along the direction surrounding the central axis L. That is, the projection of the inner wall of the second through-hole 4112 onto 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 outwards.

[0068] In some embodiments, the atomizer 1000 further includes a liquid-absorbing element 610, which may be disposed on the side of the base body 210 facing the first seal 410. In some embodiments, the side of the base body 210 facing the first seal 410 may have an embedding groove 213, which may be opposite to and communicate with the second through hole 4112, and the liquid-absorbing element 610 may be disposed in the embedding groove 213. During use, condensate and leaked atomizing matrix can enter the embedding groove 213 through the second through hole 4112 and be absorbed by the liquid-absorbing element 610. Thus, further leakage of condensate and leaked atomizing matrix to the outside of the atomizer 1000 can be prevented.

[0069] In some embodiments, the absorbent 610 may be made of an oil-absorbing material such as a cotton pad or a sponge.

[0070] As shown in Figures 4 to 6, the atomizer 1000 also includes an air supply pipe 120, and an airflow channel 1201 is configured inside the air supply pipe 120. In the embodiment, the air supply pipe 120 can be disposed in the oil cup 110, and the airflow channel 1201 inside the air supply pipe 120 can be isolated from the liquid storage chamber 1101.

[0071] In some embodiments, the end of the air supply tube 120 facing the mouthpiece 130 can be integrally connected to the oil cup 110 and communicate with the mouthpiece 130. The end of the air supply tube 120 away from the mouthpiece 130 can abut against the end face of the extension 320 away from the support body 310, and the air supply tube 120 and the extension 320 are sealed together. In addition, the end of the extension 320 away from the support body 310 is also provided with a fourth through hole 321 communicating with the assembly cavity 302. The airflow channel 1201 and the atomization channel 5101 can be connected through the fourth through hole 321, and the airflow 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 atomizing core 510 can be delivered to the mouthpiece 130 through the air supply channel 620 for the user to inhale.

[0072] In some embodiments, the atomizer 1000 further includes a second seal 420, which is configured to seal the air delivery passage 620 when the atomizer 1000 is not in use. In some embodiments, the second seal 420 may include a first handle portion 422 and a first plunger portion 421. The first handle portion 422 may be fixedly connected to one end of the first plunger portion 421 by means of integral connection or adhesive bonding.

[0073] In this embodiment, the first plunger portion 421 can be sequentially inserted from one end of the mouthpiece 130 into the airflow channel 1201, the fourth through hole 321, and the atomization channel 5101 (i.e., the air delivery channel 620). The first handheld portion 422 can be positioned on the side of the mouthpiece 130 away from the base 200 so that the user can reach and hold it. When the atomizer 1000 needs to be used, the user can hold the first handheld portion 422 to pull the second seal 420, causing the first plunger portion 421 to be pulled out of the air delivery channel 620.

[0074] In some embodiments, at least one third sealing flange 423 protrudes from the periphery of the first plunger portion 421. The third sealing flange 423 can be disposed around the periphery of the first plunger portion 421, that is, the third sealing flange 423 has an annular structure. The side of the third sealing flange 423 opposite to the first plunger portion 421 can abut against the inner wall of the gas delivery pipe 120 facing the airflow channel 1201, and the third sealing flange 423 can be interference-fitted with the inner wall of the gas delivery pipe 120 to achieve sealing of the gas delivery channel 620.

[0075] In some embodiments, three third sealing flanges 423 may protrude from the periphery 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 uniformly or non-uniformly distributed. This extends the sealing path of the air delivery channel 620 and reduces the probability of air leakage.

[0076] In some embodiments, the second seal 420 may be made of a flexible material such as silicone or rubber.

[0077] As shown in Figures 4 to 6, the atomizer 1000 further includes a third sealing element 430. The third sealing element 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 integral connection or adhesive bonding. The number of second plunger portions 431 may be equal to the number of air inlets 212 on the base 200, and the second plunger portions 431 may be arranged in a one-to-one correspondence with the air inlets 212.

[0078] In this embodiment, the second plunger portion 431 can be inserted into the air inlet 212, and the second plunger portion 431 can be sealed with the inner wall of the air inlet 212 to achieve a seal of the air inlet 212. In some embodiments, the peripheral surface of the second plunger portion 431 can be interference-fitted with the inner wall of the air inlet 212.

[0079] In some embodiments, a sealing flange may also be provided protruding from the periphery of the second plunger portion 431, and the sealing flange may be provided around the periphery of the second plunger portion 431. The side of the sealing flange opposite to the second plunger portion 431 may abut against the inner wall of the air inlet 212 and be interference-fitted with the inner wall of the air inlet 212.

[0080] In this embodiment, the second handheld part 432 may be located on the side of the base body 210 opposite to the first seal 410, so as to facilitate the user's access and grip. When it is necessary to pull out the third seal 430, the user can hold the second handheld part 432 to pull the third seal 430, so that the second plunger part 431 is pulled out from the air inlet 212.

[0081] In some embodiments, the third seal 430 may be made of a flexible material such as silicone or rubber.

[0082] When the atomizer 1000 is not in use, such as during transportation or when taking it out, the first plunger portion 421 of the second seal 420 can be inserted into the air delivery channel 620 through the mouthpiece 130, and the second plunger portion 431 of the third seal 430 can be inserted into the air inlet 212. This achieves a seal inside the atomizer 1000, preventing leakage of the atomizing matrix in the liquid reservoir 1101 due to pressure changes or shaking. Simultaneously, it also prevents dust and other contaminants from entering the atomizer 1000 through the air delivery channel 620 and the air inlet 212.

[0083] When the user needs to use the atomizer 1000, the second seal 420 and the third seal 430 can be pulled out to connect the air delivery channel 620 and the air inlet 212 to the external environment.

[0084] The embodiment also provides an atomizing device, including a power supply structure and an atomizer 1000 provided in the embodiment. The power supply structure can be connected to one end of the atomizer 1000 near the base 200, and the power supply structure can be electrically connected to the conductive electrode 520 in the atomizer 1000. Thus, the power supply structure can supply power to the atomizer 1000.
