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.

[0046] Please see Figure 1 This invention provides an atomizer 100, which can be used with a battery rod to form an electronic atomization device. The battery rod contains a power supply and a control circuit, and the control circuit is used to control the power supply to provide power to the atomizer 100.

[0047] Combination Figure 2 As shown, the atomizer 100 includes an oil cup 10 and an atomizing assembly 200. The atomizing assembly 200 is installed in the lower end of the oil cup 10 and forms a liquid storage chamber 13 with the oil cup 10. The atomizing assembly 200 includes a top assembly 20, a heating assembly 30, and a bottom assembly 40 (combined with...). Figure 6 (As shown).

[0048] Combination Figure 3 , Figure 5 and Figure 8 As shown, the top assembly 20 includes a seal 22, a bracket 21, and an air passage 23. The seal 22 is fitted onto the top of the bracket 21 and is sealed to the inner wall of the oil cup 10. A receiving space 211 is recessed on one side of the bracket 21 (in conjunction with...). Figure 7 As shown, the heating component 30 includes an oil guide body 31 vertically installed on one side of the receiving space 211 and a heating element 32 attached to one side of the oil guide body 31. The oil guide body 31 is a flat oil-absorbing cotton, and the plane that is attached to one side of the receiving space 211 is the liquid-absorbing surface. The plane on the other side opposite to the liquid-absorbing surface and facing the receiving space 211 is the atomizing surface. The heating element 32 is disposed on the atomizing surface of the oil guide body 31.

[0049] The bottom assembly 40 includes a base 41 that is fixed to the bottom of the bracket 21 in a horizontal direction and two electrodes 42 that pass through the base 41 from bottom to top. The upper ends of the two electrodes 42 extend into the receiving space 211, so that the heating element 32 is clamped between the two electrodes 42 and the oil guide body 31 in a horizontal direction. The two ends of the heating element 32 are electrically connected to the two electrodes 42 respectively. The air passage 23 is installed in the receiving space 211 and forms an atomizing chamber 231 between it and the heating assembly 30. One end of the atomizing chamber 231 is connected to the air inlet channel 415 in the base 41, and the other end is connected to the air guide tube 12 through the air outlet 213.

[0050] Among them, combined Figure 9 As shown, a liquid inlet channel 222 is provided on the side wall of the sealing member 22. The upper end of the liquid inlet channel 222 is connected to the liquid storage chamber 13. The bracket 21 is provided with a liquid inlet 212 on the other side opposite to the receiving space 211. The liquid inlet 212 is connected to the lower end of the liquid inlet channel 222 and extends through the receiving space 211. The liquid absorption surface of the oil guide body 31 covers the liquid inlet 212, so that the atomized liquid in the liquid storage chamber 13 can be guided into the oil guide body 31 through the liquid inlet channel 222 and the liquid inlet 212. The oil guide body 31 conducts the absorbed atomized liquid to the atomizing surface to contact the heating element 32. When the heating element 32 is energized and heats up, it heats and atomizes the contacted atomized liquid, thereby generating an inhalable aerosol in the atomizing chamber 231.

[0051] It should be understood that, in this embodiment, a liquid inlet groove communicating with the liquid inlet 212 may also be provided on the side wall of the bracket 21. The upper end of the liquid inlet groove extends out of the top surface of the bracket 21 and together with the seal 22 and the inner wall of the oil cup 10, forms a liquid inlet channel 222.

[0052] Combination Figure 4 As shown, the heating element 32 is a metal sheet formed by etching conductive metal, such as nickel-chromium, iron-chromium-aluminum, or stainless steel parts, which can be made by etching or laser cutting. The thickness of the heating element is 0.05-0.2mm, specifically 0.08mm, 0.1mm, or 0.15mm, with 0.15mm being the preferred thickness.

[0053] The heating element includes two conductive parts 321 and a heating part 322 connected in series between the two conductive parts 321. The heating part 322 has a first end and a second end along its longitudinal direction. The first end of the heating element 32 is near the air outlet 213, and the second end is near the air inlet channel 415. The two conductive parts 321 are respectively connected to the first end and the second end of the heating part 322. The conductive part 321 on the first end is also connected to a first support part 323. An adsorption structure 3233 for adsorbing condensate is formed on the first support part 323. When the user inhales into the air inlet 11, the airflow entering the atomizing chamber 231 from the air inlet channel 415 is blown from the second end of the heating element 32 towards the first end during the mixing process with the aerosol generated by the heating of the heating element 32. Thus, the adsorption structure 3233 on the first support part 323 can be used to adsorb the condensate in the mixed gas. Preferably, the adsorption structure 3233 consists of several rows of circular holes or grooves, which can store some condensate while adsorbing it, thus preventing condensation and leakage.

[0054] It should be noted that in this embodiment, the first support portion 323 is disposed at the first end of the heating element 32 and located outside the heating element 322. In other embodiments, the first support portion 323 may also be disposed within the area of ​​the heating element 322, as long as it is close to the first end, and the functions of preventing condensation and leakage can be achieved in the same way.

[0055] Specifically, the first support part 323 has an L-shaped structure, including a vertically connected connecting section 3231 and a support section 3232. The connecting section 3231 is connected to the connection between the conductive part 321 and the heating part 322. The support section 3232 extends laterally, and its length is greater than or equal to the width of the heating part 322 in the lateral direction. The adsorption structure 3233 is disposed on the support section 3232, so that the adsorption structure 3233 is laterally arranged in the atomizing chamber 231 to maximize its condensation function.

[0056] In this embodiment, one conductive part 321 is connected to the first end of the heating part 322 and extends along one side in a lateral direction, while the other conductive part 321 is connected to the second end of the heating part 322 and extends along the other side in a lateral direction. Thus, the upper ends of the two electrodes 42 on the base 41 press the two conductive parts 321 tightly against the oil guide body 31, so that the heating element 32 is pressed firmly against the atomizing surface of the oil guide body 31. The electrodes 42 do not exert a lateral force on the heating element 32, preventing deformation of the heating element 32 due to lateral force and subsequent separation from the oil guide body 31, thus ensuring the atomization effect of the heating element 32. The oil guide body 31 uses absorbent cotton, resulting in a large atomization volume of the atomizer 100, a good vaping experience, and high flavor reproduction of the atomized liquid.

[0057] Specifically, the heating element 322 has an S-shaped or continuous S-shaped curved structure, including several first heating segments 3221. The several first heating segments 3221 are arranged longitudinally at intervals and extend basically in the transverse direction. One end of two adjacent first heating segments 3221 is connected together through a second heating segment 3222, and the other end is separated from each other. The two free ends of the heating element 322 are located on both sides in the transverse direction and are connected to two conductive parts 321 one by one. That is to say, the conductive part 321 and the connected first heating segment 3221 are on the same straight line. The conductive part 321 has a long rectangular structure, which can be easily pressed and attached to the oil guide body 31 by the electrode 42. Its width is greater than the width of the first heating segment 3221, so that the resistance of the conductive part 321 is much smaller than that of the heating element 322. Therefore, when the heating element 32 is energized and heated, the conductive part 321 hardly generates heat, so that the heat is concentrated in the area of ​​the heating element 322 to ensure the best atomization effect.

[0058] Preferably, the second heating segment 3222 is an arc shape that bulges outward from the center, which can improve the uniform distribution of heat along the longitudinal direction when the heating part 32210 is heating. Of course, in other embodiments, the second heating segment 3222 can also be a straight line segment perpendicular to the first heating segment 3221, that is, the second heating segment 3222 extends longitudinally.

[0059] In practical applications, combined with Figure 6As shown, two conductive parts 321 are welded and fixed to the same side of the two electrodes 42 respectively. During assembly, the oil guide body 31 can be installed into the receiving space 211 first, and then the bottom component 40 with the heating element 32 welded on can be snapped and fixed to the bracket 21 in the horizontal direction, thereby pressing the heating element 32 onto the atomizing surface of the oil guide body 31; then the air passage component 23 is sealed and installed into the receiving space 211, thereby forming the atomizing component 200 as a whole; finally, the atomizing component 200 is inserted into the opening end 14 of the oil cup 10 to complete the assembly of the entire atomizer 100. This structure allows the components to be assembled in a vertical or horizontally stacked manner, without the need to bend and wrap the heating element 32, solving the problem that the robotic arm is not easy to operate because the oil guide body 31 and the heating element 32 are soft. It can realize automated and batch assembly, improve production efficiency, and reduce costs.

[0060] Furthermore, to ensure a tight fit between the heating element 32 and the oil guide 31, a second support portion 324 is connected to each second heating segment 3222. The second support portion 324 extends laterally, and its extension length does not exceed half of the conductive portion 321, so that when the conductive portion 321 is welded to the perpendicular electrode 42, the second support portion 324 avoids contact with the electrode 42. The width of the first support portion 323 and the second support portion 324 is greater than the width of the first heating segment 3221, so that when the heating element 32 is energized and heats up, the first support portion 323 and the second support portion 324 only generate a small amount of heat, which concentrates the heat generated by the heating element 32 into the heating portion 322, thereby maximizing the atomization effect.

[0061] Combination Figure 10 As shown, the air passage component 23 protrudes towards the heating element 30, forming two abutment portions 233. These two abutment portions 233 press against the conductive portions 321 at both ends of the heating element 32, and simultaneously press the second support portions 324 on both sides of the lateral direction against the atomizing surface of the oil guide 31, thereby increasing the fit between the heating element 32 and the oil guide 31 and improving atomization efficiency. Therefore, the first support portion 323 and the second support portion 324 can also extend obliquely to extend as far as possible into the blank area of ​​the atomizing surface of the oil guide 31, for example, around the heating element 322. Furthermore, when the air passage component 23 is assembled into the receiving space 211, at least one abutment portion 233 can be pressed against the support section 3232, further improving the fit between the heating element 32 and the oil guide 31.

[0062] Furthermore, the air passage 23 is positioned by abutting against the oil guide body 31 via the supporting portion 233, facilitating automated assembly. Preferably, the two supporting portions 233 are located inside the two electrodes 42, thereby forming an atomization chamber 231 together with the heating element 30, and placing the two electrodes 42 outside the atomization chamber 231 to prevent the generated aerosol from forming condensate on the electrodes 42.

[0063] The second support portion 324 may have a perforated hole to reduce the heat generated by the heating portion 322 when it heats up and conducts it to the second support portion 324, thereby reducing the heat loss of the second support portion 324 and improving the heat utilization rate.

[0064] It should be noted that the bottom component 40 may also include a partition 43 stacked on top of the base 41 and located between the base 41 and the support 21. An air intake channel 415 is formed between the partition 43 and the base 41. The partition 43 has an air passage 431 that communicates with the air intake channel 415 and the atomizing chamber 231 respectively. The bottom wall of the base 41 is provided with an air intake hole 412 that communicates with the air intake channel 415. When the user inhales into the inhalation port 11, the outside air first enters the air intake channel 415 between the partition 43 and the base 41, and then enters the atomizing chamber 231 through the air passage 431. After mixing with the aerosol generated by the heating element 32, it can be output through the air outlet 213, the air guide tube 12 and the inhalation port 11 in sequence for the user to inhale.

[0065] 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.

[0066] 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.
