[0046] like Figure 1 and Figure 2 As shown, an atomizer 1000 is provided in the embodiment, including a liquid storage cup 100, an atomizing component 200 and a base component 300.

[0047] In some embodiments, one end of the reservoir 100 has an opening 102. The opening 102 may be located at one end of the reservoir 100 along the axial direction of the atomizer 1000. The axial direction of the atomizer 1000 may refer to the direction of extension of the axis L.

[0048] like Figures 2 to 4 As shown, in this embodiment, the base assembly 300 can be installed on the end of the liquid storage cup 100 near the opening 102, and can close the opening 102. The base assembly 300 can also cooperate with the liquid storage cup 100 to define a liquid storage chamber 101 for storing the atomized matrix. In some embodiments, the base assembly 300 may include a base 310, a bracket 320, and a seal 330. The bracket 320 is installed on the side of the base 310 facing the liquid storage chamber 101. The seal 330 can be sealingly connected between the base 310 and the bracket 320. In some embodiments, a guide post 333 protrudes from the seal 330, and a guide hole 3211 adapted to the guide post 333 can be formed on the bracket 320 and / or the base 310. The guide post 333 can be inserted into the guide hole 3211 so that the seal 330 is positioned and installed on the bracket 320 and / or the base 310.

[0049] In this embodiment, the atomizing component 200 can be installed on the base component 300 and connected to the liquid storage chamber 101. During use, the atomizing component 200 can obtain the atomizing matrix from the liquid storage chamber 101 and heat and atomize the atomizing matrix to generate an aerosol for the user to inhale.

[0050] In this embodiment, the seal 330 is connected to the bracket 320 and / or the base 310 by a guide post 333 and a guide hole 3211. This improves the installation stability between the seal 330 and the bracket 320 and / or the base 310, reduces the probability of the seal 330 separating from the bracket 320 and / or the base 310, and ensures that the subsequent installation of the base assembly 300 onto the liquid storage cup 100 is smooth and fast.

[0051] Furthermore, in this embodiment, the base 310, bracket 320, and seal 330 in the base assembly 300 can be assembled to form a stable overall structure, and the atomizing component 200 can be installed in the base assembly 300. That is, the base assembly 300 and the atomizing component 200 can be assembled to form a stable overall structure, which can be referred to as an atomizing-base module, realizing modular design. The atomizing-base module can be used as a universal module in the atomizing device parts library and can be applied to different models of atomizing devices to reduce the production cost of atomizing devices.

[0052] like Figure 2As shown, in some embodiments, the liquid reservoir 100 may include a housing 110 and an air delivery tube 120. An opening 102 may be formed at one end of the housing 110 along the axial direction of the atomizer 1000. The air delivery tube 120 may be disposed within the housing 110, and the end of the air delivery tube 120 facing away from the opening 102 may be integrally formed with the housing 110. The end of the housing 110 facing the opening 102 may protrude relative to the end of the air delivery tube 120 facing the opening 102. Additionally, the end of the housing 110 facing away from the opening 102 has a first through-hole 111 communicating with the air delivery tube 120. In use, the air delivery tube 120 can communicate with the nozzle in the atomizing device through the first through-hole 111.

[0053] In some embodiments, the liquid storage chamber 101 may be located between the housing 110 and the gas delivery pipe 120, that is, the liquid storage chamber 101 may be disposed around the periphery of the gas delivery pipe 120. Accordingly, the housing 110, the gas delivery pipe 120, and the base assembly 300 may cooperate to define the liquid storage chamber 101. During the assembly of the atomizer 1000, the atomizing matrix may be injected into the liquid storage chamber 101 through the opening 102, and the opening 102 may be closed by the base assembly 300.

[0054] In some embodiments, the atomizer 1000 further includes a first liquid suction member 400, which may be disposed on the side of the liquid reservoir 100 opposite to the outlet 102. In use, the end of the liquid reservoir 100 opposite to the outlet 102 may face the nozzle in the atomizing device, and the first liquid suction member 400 can be used to absorb the condensate generated at the nozzle location, which can reduce the probability of leakage problems.

[0055] In some embodiments, the liquid storage cup 100 has an annular groove 103 on the side opposite to the outlet 102, and the groove 103 may be arranged around the periphery of the first through hole 111. The first liquid suction member 400 may be annular and disposed in the groove 103.

[0056] like Figures 3 to 6 As shown, in some embodiments, the base 310 includes an integral base plate 311 and a connecting edge 312. The base plate 311 covers the opening 102 of the liquid storage cup 100 and is positioned against the end face of the housing 110 opposite to the settling groove 103. The connecting edge 312 may be annular and protrude from the side of the base plate 311 facing the gas delivery pipe 120. The connecting edge 312 can be inserted into the housing 110 and connected to the housing 110 by means of snap-fit ​​or screw connection. Furthermore, the connecting edge 312 and the base plate 311 can cooperate to form a receiving cavity 313 facing the gas delivery pipe 120.

[0057] like Figures 2 to 7As shown, in some embodiments, the seal 330 may include an integral sealing portion 332 and a supporting portion 331. The sealing portion 332 may have an annular structure. One end of the sealing portion 332 along the axial direction of the atomizer 1000 may be disposed around the periphery of the connecting edge 312 and seal against the inner wall of the liquid storage cup 100 facing the liquid storage cavity 101, wherein the inner wall of the liquid storage cup 100 may refer to the inner wall of the housing 110 facing the liquid storage cavity 101. Thus, the sealing portion 332 can achieve a seal at the connection point between the base 310 and the liquid storage cup 100, reducing the probability of leakage.

[0058] In some embodiments, the other end of the sealing portion 332 along the axial direction of the atomizer 1000 can be sealed against the inner wall of the bracket 320 and the housing 110 on the side facing the liquid storage chamber 101. Thus, the sealing portion 332 can achieve a seal at the connection position between the bracket 320 and the liquid storage cup 100, reducing the probability of leakage.

[0059] In this embodiment, the support portion 331 can be connected to the side of the sealing portion 332 facing away from the inner wall of the liquid storage cup 100, and is located between the base 310 and the bracket 320. That is, the support portion 331 can be located inside the sealing portion 332. The guide post 333 can be protruding from the side of the support portion 331 facing the bracket 320. Correspondingly, the guide hole 3211 can be formed on the bracket 320. During the assembly of the base assembly 300, the cooperation between the guide post 333 and the guide hole 3211 can provide positioning and guiding functions for the assembly of the bracket 320, enabling the bracket 320 to be accurately and quickly installed on the sealing element 330 and the base 310. It can also facilitate the automated assembly of the base assembly 300 and improve the assembly accuracy.

[0060] In some embodiments, the guide post 333 may protrude from the side of the support portion 331 facing the base 310, and correspondingly, the guide hole 3211 may be formed on the base 310. During the assembly of the base assembly 300, the cooperation between the guide post 333 and the guide hole 3211 provides positioning and guiding functions for the assembly of the seal 330, enabling the seal 330 to be accurately and quickly installed on the base 310. It also facilitates the automated assembly of the base assembly 300 and improves assembly accuracy.

[0061] In some embodiments, guide posts 333 protrude from both the side of the support portion 331 facing the bracket 320 and the side of the support portion 331 facing the base 310. Guide holes 3211 adapted to the corresponding guide posts 333 can be provided on both the base 310 and the bracket 320. The guide posts 333 can be inserted into the guide holes 3211 at opposite positions.

[0062] In some embodiments, the seal 330 may include two opposing support portions 331, which may be symmetrically arranged about axis L. Accordingly, each of the two support portions 331 has a guide post 333 protruding from the side facing the bracket 320. The bracket 320 may have two corresponding guide holes 3211, and the two guide posts 333 are inserted into the two guide holes 3211 one-to-one.

[0063] In some embodiments, the seal 330 may also include one, three, four, or other numbers of support portions 331. At least one support portion 331 has at least one guide post 333 protruding from the side facing the bracket 320. The bracket 320 may have guide holes 3211 equal in number to the guide posts 333, and these holes are arranged one-to-one with the guide posts 333. Each guide post 333 can be inserted into its corresponding guide hole 3211.

[0064] In some embodiments, a first inclined surface 3332 is disposed on the periphery of the guide post 333. Along the insertion direction of the guide post 333 into the guide hole 3211, the first inclined surface 3332 may gradually tilt towards the direction closer to the central axis of the guide post 333. In some embodiments, the insertion direction of the guide post 333 into the guide hole 3211 may be parallel to the axial direction of the atomizer 1000 and point towards the end of the liquid reservoir 100 away from the opening 102. Correspondingly, the first inclined surface 3332 gradually tilts towards the direction closer to the central axis of the guide post 333 from the end near the base 310 to the end away from the base 310, that is, the peripheral surface of the guide post 333 may be tapered. Thus, when assembling the bracket 320 and the seal 330, the insertion of the guide post 333 into the guide hole 3211 provides a guiding function, facilitating the insertion of the guide post 333 into the guide hole 3211, improving assembly efficiency, and facilitating the automated assembly of the base assembly 300.

[0065] like Figures 3 to 6 As shown, in some embodiments, the bracket 320 may include an integral bracket body 321 and an extension 322. The end of the sealing portion 332 away from the base 310 can seal against the periphery of the bracket body 321 and the inner wall of the housing 110, thereby sealing the connection between the bracket 320 and the liquid storage cup 100 and reducing the probability of leakage. The side of the bracket body 321 facing the base 310 can abut against the support portion 331.

[0066] In this embodiment, the guide hole 3211 may be formed on the side of the support body 321 facing the base 310. In some embodiments, the guide hole 3211 may be a through-hole structure that penetrates the support body 321 along the axial direction of the atomizer 1000. Correspondingly, the end of the guide hole 3211 opposite to the base 310 may communicate with the liquid storage chamber 101, and the end of the guide post 333 opposite to the support portion 331 may be exposed relative to the liquid storage chamber 101. In addition, the guide post 333 may seal against the inner wall of the guide hole 3211, thereby achieving a seal between the guide post 333 and the inner wall of the guide hole 3211 and reducing the probability of leakage.

[0067] In some embodiments, the guide hole 3211 may also be a blind hole facing the base 310, that is, the end of the guide hole 3211 facing the liquid storage cavity 101 may be a closed structure. The guide post 333 may be inserted into the guide hole 3211 and fit against the inner wall of the guide hole 3211.

[0068] like Figure 3 , Figure 4 , Figure 8 and Figure 9 As shown, in some embodiments, a first air-guiding channel 3331 is provided on the periphery of the guide post 333. One end of the first air-guiding channel 3331 can communicate with the liquid storage chamber 101, and the end of the first air-guiding channel 3331 away from the liquid storage chamber 101 can communicate with the external environment. Thus, during the use of the atomizer 1000, the gas in the external environment can enter the liquid storage chamber 101 through the first air-guiding channel 3331 to balance the air pressure in the liquid storage chamber 101, ensuring that the atomizing matrix in the liquid storage chamber 101 can smoothly enter the atomizing component 200 through the liquid inlet 3222, ensuring the consistency of taste during the user's inhalation process, and also reducing the possibility of the atomizing component 200 burning due to dry burning.

[0069] In some embodiments, the first air passage 3331 may also be formed on the inner wall of the guide hole 3211.

[0070] In some embodiments, the first air guide channel 3331 can be simultaneously formed on the inner wall of the guide hole 3211 and the periphery of the guide post 333, so that the first air guide channel 3331 can be defined by the cooperation of the inner wall of the guide hole 3211 and the guide post 333.

[0071] In some embodiments, the first air passage 3331 may be a straight groove structure formed around the guide post 333 and extend generally along the axial direction of the atomizer 1000. The first air passage 3331 may extend from one end of the guide post 333 near the support portion 331 to the other end of the guide post 333 away from the support portion 331.

[0072] In some embodiments, the first air guide channel 3331 may also be a non-linear groove structure such as a spiral groove or an S-shaped groove surrounding the guide post 333, thereby extending the extension path of the first air guide channel 3331 and reducing the probability of the atomized matrix in the liquid storage chamber 101 leaking outward through the first air guide channel 3331.

[0073] In some embodiments, the first air passage 3331 may also be a through hole structure opened inside the guide post 333.

[0074] In some embodiments, a second air guide channel 3311 communicating with the first air guide channel 3331 may be provided on the side of the support portion 331 facing the bracket 320. The second air guide channel 3311 may be a groove structure formed on the side of the support portion 331 facing the bracket 320. The end of the second air guide channel 3311 away from the first air guide channel 3331 may be connected to the cavity 313. Correspondingly, the end of the first air guide channel 3331 away from the liquid storage cavity 101 may be connected to the external environment in sequence through the second air guide channel 3311, the cavity 313, and the air inlet 3111.

[0075] In some embodiments, the first air passage 3331 may be directly connected to the accommodating cavity 313.

[0076] like Figure 4 , Figure 9 and Figure 10 As shown, in some embodiments, the depth and width of each air guiding channel (including the first air guiding channel 3331 and the second air guiding channel 3311) can be set to be the same, and the depth H of each air guiding channel can be set to 0.3 mm, and the width M of each air guiding channel can be set to 0.25 mm. Therefore, each air guiding channel can have a small cross-sectional area while still fulfilling its air guiding function, reducing the possibility of leakage of the atomizing matrix from the liquid storage chamber 101 through each air guiding channel.

[0077] In this embodiment, the sealing element 330 can simultaneously achieve the functions of sealing between the base 310 and the housing 110, sealing between the bracket 320 and the housing 110, and regulating the pressure of the liquid storage chamber 101 in relation to the external environment. This reduces the number of parts in the atomizer 1000, lowers the production cost of the atomizer 1000, and improves the assembly efficiency of the atomizer 1000.

[0078] like Figures 3 to 6 As shown, in this embodiment, the extension 322 protrudes from the side of the bracket body 321 opposite to the base 310. The bracket 320 has an assembly cavity 3201 on the side opposite to the base 310. The assembly cavity 3201 can pass through the extension 322 along the axial direction of the atomizer 1000 and extend into the interior of the bracket body 321.

[0079] In some embodiments, notches 3221 may be provided on opposite sides of the extension 322. The outer wall of the extension 322 at the notch 3221 may be spaced apart from the inner wall of the housing 110. The outer wall of the extension 322 may refer to the surface of the extension 322 facing away from the assembly cavity 3201. Correspondingly, the liquid storage cavity 101 may extend to the notch 3221 of the extension 322, that is, the liquid storage cavity 101 may extend between the extension 322 and the housing 110.

[0080] In some embodiments, the periphery of the extension 322 may also be provided with one, three, four, or any other number of notches 3221.

[0081] In some embodiments, the outer wall of the extension 322 may be spaced apart from the inner wall of the housing 110 on the side facing the liquid storage cavity 101. That is, a portion of the liquid storage cavity 101 may be arranged around the periphery of the extension 322.

[0082] In some embodiments, the side of the extension 322 facing the notch 3221 is configured as a third inclined surface 3223. The third inclined surface 3223 may gradually slope away from the end away from the support body 321 to the end close to the support body 321, moving away from the assembly cavity 3201. Thus, when the base assembly 300 is assembled into the liquid storage cup 100, it is convenient for the extension 322 to be inserted into the liquid storage cavity 101 containing the atomizing matrix, and the third inclined surface 3223 can also provide a guiding function for the atomizing matrix in the liquid storage cavity 101, allowing the atomizing matrix to move into the space between the extension 322 and the housing 110.

[0083] In some embodiments, the periphery of the extension 322 is provided with a liquid inlet hole 3222 that communicates with the assembly cavity 3201, and the liquid inlet hole 3222 can communicate with the notch 3221, thereby enabling the liquid inlet hole 3222 to communicate with the liquid storage cavity 101. In the embodiments, the extension 322 may have one, two, three, or any other arbitrary number of liquid inlet holes 3222 at the position corresponding to each notch 3221.

[0084] In some embodiments, the inner wall of the liquid inlet 3222 may be provided with a second inclined surface 3224, which may be located on the side of the liquid inlet 3222 away from the support body 321. In the embodiments, the second inclined surface 3224 may gradually slope from the end away from the atomizing component 200 to the end closer to the atomizing component 200 towards the support body 321. Thus, when the atomizer 1000 is inverted, it can prevent the atomizing substrate from adhering to the second inclined surface 3224, thereby reducing the possibility of the atomizing substrate entering the atomizing component 200 during the storage and transportation of the atomizer 1000, and reducing the probability of core clogging and leakage problems. The atomizer 1000 can be placed inverted during storage and transportation. Furthermore, during the use of the atomizer 1000, the second inclined surface 3224 can provide a guiding and drainage function for the atomizing substrate, facilitating the smooth delivery of the atomizing substrate through the liquid inlet 3222 towards the atomizing component 200.

[0085] like Figure 2 and Figure 5 As shown, in this embodiment, one end of the gas supply pipe 120 facing the opening 102 can be inserted into the assembly cavity 3201 and sealed with the inner wall of the assembly cavity 3201. In some embodiments, an annular sealing flange 3225 protrudes from the inner wall of the receiving cavity 313 facing the gas supply pipe 120, that is, the sealing flange 3225 can be arranged around the axis L. The sealing flange 3225 can seal against the side surface of the gas supply pipe 120 facing the inner wall of the assembly cavity 3201. In some embodiments, the sealing flange 3225 can seal against the side surface of the gas supply pipe 120 facing the inner wall of the assembly cavity 3201 by interference fit, and can realize the relative fixation between the bracket 320 and the gas supply pipe 120.

[0086] In some embodiments, the side surface of the gas pipe 120 facing the inner wall of the assembly cavity 3201 can also be sealed and relatively fixed with the inner wall of the assembly cavity 3201 by means of adhesive or other methods.

[0087] like Figure 3 , Figures 4 to 6As shown, in some embodiments, the atomizing component 200 can be installed in the assembly cavity 3201 and communicate with the liquid storage cavity 101 through the liquid inlet 3222. In the embodiments, the atomizing component 200 may include a solid atomizing core 210 and a liquid guide 220. The liquid guide 220 is disposed around the periphery of the solid atomizing core 210, and the side surface of the liquid guide 220 facing away from the solid atomizing core 210 is in contact with the inner wall of the assembly cavity 3201 and can communicate with the liquid storage cavity 101 through the liquid inlet 3222. In addition, an atomizing channel 201 is formed in the solid atomizing core 210, which can communicate with the gas delivery pipe 120. In use, the liquid guide 220 can obtain the atomizing matrix from the liquid storage cavity 101 through the liquid inlet 3222 and transport the atomizing matrix to the solid atomizing core 210, whereby the solid atomizing core 210 heats and atomizes the atomizing matrix to generate an aerosol. In some embodiments, the solid atomizing core 210 may be a ceramic atomizing core.

[0088] In some embodiments, the solid atomizing core 210 may also be a metal atomizing core or a glass atomizing core.

[0089] In some embodiments, the liquid guiding component 220 may be a structure such as liquid guiding cotton.

[0090] In this embodiment, the bracket body 321 is also provided with a second through hole 3212 that communicates with the assembly cavity 3201. The end of the atomizing channel 201 away from the air supply pipe 120 can communicate with the accommodating cavity 313 through the second through hole 3212, and then with the air inlet 3111.

[0091] In some embodiments, the base assembly 300 further includes a second liquid-absorbing member 340, which is disposed on the side of the base plate 311 facing the bracket 320 and accommodated in the receiving cavity 313. In use, the second liquid-absorbing member 340 can be used to absorb condensate and leaked atomizing matrix, thereby reducing the possibility of further leakage of atomizing matrix and condensate to the outside of the atomizer 1000.

[0092] In some embodiments, the base plate 311 has an extended protrusion 314 protruding from the side facing the support 320. One end of the extended protrusion 314 facing the support 320 may protrude relative to the side of the second liquid suction member 340 facing the support 320. In this embodiment, the air inlet 3111 may extend through the extended protrusion 314 along the axial direction of the atomizer 1000. This prevents the condensate and atomizing matrix absorbed in the second liquid suction member 340 from leaking outward from the air inlet 3111.

[0093] like Figure 5 and Figure 6 As shown, in some embodiments, the base assembly 300 further includes two conductive electrodes 350. One conductive electrode 350 can be used as a positive electrode, and the other conductive electrode 350 can be used as a negative electrode.

[0094] In some embodiments, the conductive electrode 350 may include an integral contact portion 351 and an electrode post 352, with the contact portion 351 located at one end of the electrode post 352. The electrode post 352 may have a columnar structure. The electrode post 352 may pass through the base plate 311 and protrude from the side of the base plate 311 toward the support 320. The electrode post 352 may be electrically connected to the solid atomizing core 210 via a wire or similar structure.

[0095] In this embodiment, the contact portion 351 may have a plate-like structure. The contact portion 351 may be embedded in the side of the base plate 311 opposite to the connecting edge 312. Furthermore, the surface of the contact portion 351 opposite to the electrode post 352 may be flush with the surface of the base plate 311 opposite to the connecting edge 312. In use, the contact portion 351 may be electrically connected to the main unit of the atomizing device, thereby allowing the main unit to control the operation of the atomizing core and supply power to the atomizing core.

[0096] In some embodiments, a limiting protrusion 315 protrudes from the side of the base plate 311 facing the connecting edge 312. The limiting protrusion 315 is disposed around the periphery of the electrode post 352. Thus, the limiting protrusion 315 can provide a limiting function for the conductive electrode 350, reducing the possibility of the limiting protrusion 315 shaking, thereby ensuring the connection stability and reliability between the conductive electrode 350 and the solid atomizing core 210.

[0097] In some embodiments, the end of the electrode post 352 away from the contact portion 351 may protrude relative to the side of the limiting protrusion 315 opposite to the base plate 311, and may be inserted into the bracket 320. This further improves the installation stability of the conductive electrode 350, ensuring the connection stability and reliability between the conductive electrode 350 and the solid atomizing core 210.

[0098] like Figures 2 to 4 As shown, in some embodiments, the atomizer 1000 may further include a first sealing plug 510 and a second sealing plug 520. When the atomizer 1000 is not in use, the first sealing plug 510 can be sealed and inserted into the first through hole 111 and the end of the air supply tube 120 away from the base assembly 300, and the second sealing plug 520 can be sealed and inserted into the air inlet 3111. Thus, when the atomizer 1000 is not in use, the liquid storage chamber 101 can be isolated from the external environment, reducing the probability of leakage and passive accidental triggering leading to coil clogging.

[0099] The embodiment also provides an atomizing device, which may include a main unit and an atomizer 1000 provided in the embodiment. The atomizer 1000 may be installed in the main unit and may be electrically connected to the main unit.
