Description

Technical Field

[0001] This invention belongs to the field of electronic atomization technology, and particularly relates to an atomizer. Background Technology

[0002] In existing electronic atomizers, the aerosols and exhaled vapor produced by the user during use easily condense inside the atomizer, forming condensate. This affects the vaping experience and overall feel, and the accumulated condensate can leak into the battery compartment, damaging components. To address this condensation issue, absorbent cotton is typically added near the inhalation port. However, this absorbent cotton is often limited and soft, resulting in a complex e-liquid cup structure, low assembly efficiency, and high costs. Furthermore, with frequent use, the absorbent cotton can become saturated, leading to continued leakage. Summary of the Invention

[0040] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0041] This invention provides an electronic atomization device, which includes a battery rod (not shown) and an atomizer. The battery rod contains a power supply and a control circuit. The control circuit controls the power supply to provide power to the atomizer. The atomizer includes an oil cup and an atomizing component installed in the oil cup.

[0042] Please see Figure 1 As shown, the oil cup 10 has an opening at the lower end and an air inlet 11 at the upper end for the user to inhale. An air guide tube 12 extending into the oil cup 10 is formed on the upper inner wall of the air inlet 11 along its periphery, and the interior of the air guide tube 12 communicates with the air inlet 11. A liquid storage chamber 13 is formed between the air guide tube 12 and the inner wall of the oil cup 10 to store the atomizing liquid. In this embodiment, the air guide tube 12 and the oil cup 10 are integrally formed.

[0043] Combination Figures 2 to 5 As shown, the atomizing assembly includes a bottom assembly, a bracket 20, and a heating assembly 30. The bracket 20 is installed inside the open end of the oil cup 10 and is sealed to the inner wall of the oil cup 10 through a sealing member 21. The bottom assembly includes a base 41 installed in the lower opening of the oil cup 10 and two electrodes 42 inserted from bottom to top into the base 41 to supply power to the heating assembly 30. The lower end of the bracket 20 is located at the upper end of the base 41, thereby clamping and positioning the heating assembly 30 between the base 41 and the bracket 20. The bracket 20 has an inlet channel 22 for supplying the atomizing liquid in the liquid storage chamber 13 to the heating assembly 30.

[0044] The base 41 has mounting channels 411 extending through its top and bottom ends. The two electrodes 42 are inserted into the two mounting channels 411 from bottom to top for fixed installation. The top ends of the two electrodes 42 are electrically connected to the heating element 30. The two electrodes 42 are used to connect to the positive and negative terminals of the power supply. The bottom ends of the two electrodes 42 are flush with or protrude from the bottom surface of the base 41, so that the atomizer can connect to the conductive contacts on the battery rod through the bottom ends of the two electrodes 42.

[0045] The heating element 30 includes an oil guide body 31 and a heating element 32 stacked on top of the base 41. The oil guide body 31 and the heating element 32 are installed on the top of the base 41, and the oil guide body 31 is in close contact with the bottom surface inside the bracket 20, thereby connecting with the liquid inlet channel 22. The oil guide body 31 is a sheet made of oil-absorbing cotton, so the oil guide body 31 contains a large number of microporous structures and has a certain porosity, which can draw in the atomized liquid in the liquid storage chamber 13 and transfer it to the bottom surface in contact with the heating element 32, so that the heating element 32 heats and atomizes the contacted atomized liquid.

[0046] The top of the base 41 is provided with an atomizing cavity 412 corresponding to the atomizing section 322 of the heating element 32. Specifically, the top of the base 41 is recessed to form a space, which forms the atomizing cavity 412 between the base 41 and the oil guide 31. The heating element 32 is preferably located on the side of the oil guide 31 facing the atomizing cavity 412, so that the tops of the two electrodes 42 can be easily electrically connected to the two ends of the heating element 32 respectively. The bottom and / or inner side of the atomizing cavity 412 are provided with multiple protruding structures or groove structures for adsorbing condensate.

[0047] It should be noted that the atomizing chamber 412 is connected to the air guide tube 12 of the oil cup 10 and the air intake channel 414 at the bottom of the base 41. When the user inhales through the inhalation port 11, the heating element 32 heats and atomizes the atomized liquid absorbed in the oil guide body 31, generating an aerosol that can be inhaled by the user in the atomizing chamber 412. At the same time, air from outside the atomizer enters the atomizing chamber 412 through the air intake channel 414, mixes with the generated aerosol, and is finally inhaled by the user through the air guide tube 12 and the inhalation port 11. During the inhalation process, some aerosol enters the atomizing chamber 412. The raised or recessed structures increase the adsorption surface area for condensate, thus collecting the condensate during the atomization process and preventing it from leaking into the battery rod and damaging the components.

[0048] In one embodiment, an air inlet pipe 413 extends protruding from the bottom of the atomizing chamber 412 towards the atomizing chamber 412, and an air inlet channel 414 communicating with the atomizing chamber 412 is formed inside the air inlet pipe 413. The air inlet pipe 413 and the base 41 are integrally formed. The air inlet pipe 413 is open at the bottom and has several air inlet holes 4131 at the top so that the air inlet channel 414 communicates with the atomizing chamber 412. Furthermore, since an annular collection groove (i.e., the bottom of the atomizing chamber 412) can be formed between the outer side of the air inlet pipe 413 and the inner side of the atomizing chamber 412, the condenser adsorbed by the protruding structure can be stored through the annular collection groove, which can prevent condensate or atomized liquid from entering the atomizing chamber 412 and flowing out from the air inlet channel 414.

[0049] Specifically, the protrusion structure at the bottom of the atomizing chamber 412 can be a hemispherical protrusion 415. Multiple hemispherical protrusions 415 are distributed on the bottom surface of the atomizing chamber 412 and around the air inlet pipe 413. Preferably, the top of the hemispherical protrusion 415 is lower than the top of the air inlet pipe 413, thereby using multiple hemispherical protrusions 415 to increase the adsorption surface area of ​​the condensate and allow the formed condensate to be stored in the annular collection tank.

[0050] In addition, the protrusion structure located inside the atomizing chamber 412 can be a strip protrusion 417. Multiple strip protrusions 417 are spaced apart and extend along the axial direction of the atomizer so that the condensate adsorbed on the surface of the strip protrusion 417 can slide down into the annular collection tank for storage.

[0051] Preferably, the two ends of the atomizing chamber 412 near the two air intake channels 414 protrude towards the central axis to form arc surfaces 416, each arc surface 416 having several strip protrusions 417, and the outer peripheral surface of the air intake pipe 413 also having several strip protrusions 417. In this way, the adsorption surface area for adsorbing condensate in the atomizing chamber 412 is greatly increased.

[0052] It should be understood that the specific structure of the protrusions in the above embodiments is merely a preferred option. In other embodiments, the protrusions on the bottom and inner side of the atomizing chamber 412 can all be hemispherical protrusions 415 or all be strip protrusions 417. Alternatively, a groove structure, such as a hemispherical groove or a strip groove or a combination thereof, can also be used in this embodiment. In other embodiments, the interval between multiple protrusions or grooves is less than 1 mm, thereby utilizing the capillary force adsorption of the protrusions or grooves to adsorb the condensate during the atomization process.

[0053] In one embodiment, the top surface of the base 41 is recessed to form a reservoir 418 for storing condensate. There are two reservoirs 418, which are located on opposite outer sides of the two mounting channels 411, for storing condensate formed on the top surface of the base 41 during the atomizer's suction process.

[0054] In one embodiment, combined Figure 5As shown, the lower end of the bracket 20 is fitted onto the top end of the base 41 to clamp and fix the heating element 30 between the bracket 20 and the base 41. Specifically, the bracket 20 includes a top wall 23 and a side wall 24 extending downward along the periphery of the top wall 23. The side wall 24 is fitted onto the upper end of the base 41, and the liquid inlet channel 22 is formed vertically through the top wall 23. The top surface of the oil guide 31 abuts against the bottom surface of the top wall 23. In practical applications, the side wall 24 is fixed to the base 41 by screwing, plugging, or snap-fit ​​connection. In this embodiment, a snap-fit ​​connection is preferred, thereby clamping and fixing the heating element 30 between the bottom surface of the top wall 23 and the top surface of the base 41, so that the oil guide 31 fits tightly against the bottom surface of the top wall 23 to cover the lower end of the liquid inlet channel 22 and prevent oil leakage. In addition, this structure allows the heating element 30 and the bracket 20 to be stacked and installed sequentially on the top of the base 41 to form a fixed whole during the assembly of the atomizing component in this embodiment. Then, the whole atomizing component is assembled into the lower opening of the oil cup 10, making the assembly more convenient and faster and improving production efficiency.

[0055] The inner side of the sidewall 24 is provided with a first return air groove 291, and the bottom surface of the top wall 23 is provided with a second return air groove 292 connected to the first return air groove 291. The end of the second return air groove 292 away from the first return air groove 291 extends to the liquid inlet channel 22. The first return air groove 291 and the second return air groove 292 together form a return air channel 29. One end of the return air channel 29 is connected to the atomizing chamber 412, and the other end is connected to the liquid inlet channel 22. When the user inhales, the atomizing liquid in the liquid storage chamber 13 is absorbed and heated by the heating component 30, resulting in a negative pressure inside the liquid storage chamber 13. When the external air mixes with the aerosol, a portion of the gas enters the liquid storage chamber 13 from the formed return air channel 29 and through the liquid inlet channel 22, thereby balancing the air pressure inside the liquid storage chamber 13 and preventing poor oil flow.

[0056] In one embodiment, the support 20 has two liquid inlet channels 22, and the bottom surface of the top wall 23 is recessed to form a connecting groove 25 connecting the two liquid inlet channels 22. The top surface of the connecting groove 25 gradually slopes downwards along the direction close to the center of the connecting groove 25. This structure facilitates the rapid conduction of the atomizing liquid to the center of the oil guide body 31. Since the heat generation is more concentrated in the center of the heating element 32, the atomizing liquid is consumed faster during atomization. In this embodiment, the connecting groove 25 can prevent dry burning caused by slow oil conduction.

[0057] Preferably, a mounting position 26 is formed in the middle of the top surface of the top wall 23, which is connected to the air guide tube 12 provided in the oil cup 10. An air passage chamber 27 is provided at the bottom of the top wall 23. A through groove 28 is formed on the inner and outer surfaces of the side wall 24, with the lower end of the through groove 28 extending to communicate with the atomizing chamber 412 and the upper end extending to communicate with the air passage chamber 27. Preferably, there are two through grooves 28, respectively located on opposite sides of the side wall 24 and respectively communicating with the air passage chamber 27. It should be understood that the upper end of the base 41 has openings on opposite sides of the atomizing chamber 412 to allow the atomizing chamber 412 to communicate with the through groove 28 when the bracket 20 is fitted onto the base 41. Thus, outside air enters the atomizing chamber 412, mixes with the aerosol, enters the air passage chamber 27 through the through groove 28, and is then inhaled by the user through the air guide tube 12.

[0058] It should be noted that the sealing element 21 is made of sealing materials such as silicone or rubber, and its bottom surface protrudes to form a sleeve portion 211 that extends into the mounting position 26. The lower end of the air guide tube 12 is inserted into the sleeve portion 211. The sleeve portion 211 is used to achieve a sealed connection between the outer side of the air guide tube 12 and the inner side of the mounting position 26, so as to prevent the atomized liquid in the liquid storage chamber 13 from leaking into the air passage chamber 27. Of course, the sleeve portion 211 can also be a separate sealing ring body that is separate from the sealing element 21.

[0059] In one embodiment, the lower end of the through groove 28 on the bracket 20 extends to the bottom end of the side wall 24, and the side of the base 41 is provided with a baffle 419 extending into the through groove 28. That is, the baffle 419 is formed by the base 41 protruding and extending towards the bracket 20. The protrusion height of the baffle 419 is adjacent to the heating element 30 and lower than the bottom surface of the heating element 30, so as to ensure that the atomizing chamber 412 can communicate with the through groove 28. In this way, the baffle 419 can be used to prevent the oil guide body 31 from leaking from the side and flowing out of the through groove 28 when the atomizer is stored for a long time.

[0060] In one embodiment, the heating element 32 is a sheet-like body, including two fixing parts 321 and an atomizing part 322 connected in series between the two fixing parts 321. The top ends of the two electrodes 42 protrude from the top end of the base 41 and abut against the two fixing parts 321 respectively, thereby realizing the electrical connection between the two electrodes 42 and the heating element 32.

[0061] In order to improve the installation strength of the heating element 32 and prevent the heating element 32 from displacing due to the vibration of the atomizer and causing it to separate from the electrode 42, a positioning hole adapted to the diameter of the top end of the electrode 42 can be opened on the fixing part 321. The top end of the electrode 42 extends into the positioning hole, so that the electrode 42 is electrically connected to the fixing part 321, while preventing the heating element 32 from separating from the electrode 42 due to vibration. Furthermore, the electrode 42 can be welded to the fixing part 321 to ensure the reliability of the atomizer.

[0062] Preferably, the atomizing part 322 can take the shape of, for example, a grid, stripe, S-shape, zigzag, wavy, sawtooth, spiral, circular, or rectangular. In this embodiment, the atomizing part 322 is S-shaped and has multiple fixing strips 323 extending to both sides. The ends of the fixing strips 323 away from the atomizing part 322 can be bent and clamped to the top of the base 41, thereby improving the fixing strength of the heating element 32. At the same time, the fixing strips 322 can also play a partial heat conduction role, so that the heat generated by the atomizing part 322 is more evenly distributed. In this embodiment, the resistance value of the atomizing part 322 of the heating element 32 is greater than the resistance value of the fixing part 321.

[0063] In an alternative embodiment, such as Figure 6 and Figure 7 As shown, when the two liquid inlet channels 22 on the bracket 20 are not connected by a connecting groove, that is, the mounting position 26 extends towards the base 41 and simultaneously penetrates the bracket 20 and the oil guide body 31, thereby forming a straight air passage 50 that communicates with the atomizing chamber 412. At this time, the two liquid inlet channels 22 are separated from each other and connected to the oil guide body 31, and there is no need to set a through groove on the bracket 20. In this embodiment, the heating element 32 also includes an annular connecting part 324. There are two atomizing parts 322. The two atomizing parts 322 are symmetrically connected to the two ends of the annular connecting part 324. The end of the atomizing part 322 away from the annular connecting part 324 is connected to the fixing part 321. Specifically, the hollow area of ​​the annular connecting portion 324 is part of the straight air passage 50. External air enters the atomizing chamber 412 through the air intake channel 414, mixes with the generated aerosol, and then enters the air guide tube 12 through the straight air passage 50. Therefore, in this embodiment, during the suction atomization process, the annular connecting portion 324 can prevent the atomized liquid on the outside of the annular connecting portion 324 from being carried away by the suction airflow, thereby avoiding the atomized liquid mixed in with the suction airflow and affecting the taste. In this embodiment, the resistance value of the atomizing portion 322 is greater than the resistance values ​​of the annular connecting portion 324 and the fixing portion 321.

[0064] In one embodiment, the heating element 30 further includes a support 33 stacked on top of the base 41, with the heating element 32 clamped and positioned between the support 33 and the oil guide 31. The support 33 has a clearance hole 331 corresponding to the atomizing part 322, and the clearance hole 331 is connected to the atomizing chamber 412 at the top of the base 41. When the atomizing part 322 of the heating element 32 is heated, the aerosol generated enters the atomizing chamber 412 through the clearance hole 331. External air enters the atomizing chamber 412 through the air intake channel 414 and mixes with the aerosol. Then, it passes through the through groove 28, the air passage 27, and the air guide tube 12 in sequence, and is finally output from the air intake hole for the user to inhale. In this embodiment, the end of the fixing strip 323 away from the atomizing part 322 can be bent and clamped to the outside of the support 33.

[0065] Preferably, the support 33 can be a rigid sheet made of insulating material such as a dense ceramic part or a silicone part, or it can be a metal part with a non-conductive outer surface or a conductive part with an insulating layer on the top surface. For example, a sheet-like support 33 can be formed by coating the top or both sides of a metal sheet such as stainless steel to isolate the metal sheet from the heating element 32.

[0066] In this embodiment, the support body 33 supports the heating element 32. The two fixing parts 321 at both ends of the heating element 32 are respectively supported on the top surfaces of the two ends of the support body 33. The two ends of the support body 33 are respectively provided with mounting holes 332, and the two mounting holes 332 on the support body 33 correspond one-to-one with the two mounting channels 411 on the base 41. The top ends of the two electrodes 42 pass through the two mounting holes 332 and abut against the two fixing parts 321 to achieve electrical connection. It should be noted that the support body 33 may not have two mounting holes 332. In this case, the clearance hole 331 on the support body 33 covers the two mounting channels 411, that is, the top ends of the two electrodes 42 extend from the mounting channels 411 and pass through the clearance hole 331 to abut against the two fixing parts 321.

[0067] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0068] The above is a description of the technical solution provided by the present invention. For those skilled in the art, based on the ideas of the embodiments of the present invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of the present invention.
