An atomizer

Abstract

This invention relates to an atomizer, comprising an oil cup and an atomizing component. The atomizing component is installed in the lower end of the oil cup, forming a liquid storage chamber with the oil cup. The top surface of the atomizing component in contact with the liquid storage chamber is a liquid-guiding slope. A liquid inlet channel communicating with the liquid storage chamber is formed between the atomizing component and the inner wall of the oil cup. The upper port of the liquid inlet channel is located at the lowest point of the liquid-guiding slope. The liquid inlet channel is used to supply the atomized liquid in the liquid storage chamber to the heating element in the atomizing component. This invention ensures smooth oil flow between the atomized liquid and the heating element even when a small amount of atomized liquid remains in the liquid storage chamber. This reduces the risk of coil clogging due to poor liquid flow when the atomizer has insufficient liquid, thus maintaining good atomization performance and preserving the product's flavor even after the atomized liquid is completely used up.

Description

Technical Field

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

[0002] The principle of an electronic atomizer is to use an internal heating element to heat and atomize the atomized liquid absorbed by the e-liquid in the wicking tube. The atomized liquid is then drawn out from the outlet inside the atomizer through vaping. The atomized liquid in an electronic atomizer is contained in the oil cup and flows through the lower e-channel to the wicking tube. Currently, the lower e-channels in electronic atomizers are usually located inside the support frame, with two channels symmetrically arranged. The wicking tube is horizontally fixed at the bottom of the lower e-channel, and the heating element is located on the lower surface of the wicking tube. However, this structure requires the airflow channel between the atomization chamber and the oil cup to bypass the wicking tube from both sides, resulting in a complex airflow path. Furthermore, when a small amount of atomized liquid remains in the atomizer, the user typically tilts the atomizer slightly during vaping, which can easily lead to uneven distribution of the atomized liquid to the two lower e-channels. This can cause uneven e-liquid delivery speeds at the two ends of the wicking tube corresponding to the lower e-channel positions, and may even lead to dry burning. Summary of the Invention

[0003] The purpose of this invention is to at least partially address the shortcomings of the prior art and provide an atomizer.

[0004] To achieve the above objectives, the present invention provides an atomizer, including an oil cup and an atomizing component. The atomizing component is installed in the lower end of the oil cup and forms a liquid storage cavity with the oil cup. The top surface of the atomizing component in contact with the liquid storage cavity is a liquid guiding slope. A liquid inlet channel communicating with the liquid storage cavity is formed between the atomizing component and the inner wall of the oil cup. The upper port of the liquid inlet channel is located at the lowest position of the liquid guiding slope. The liquid inlet channel is used to supply the atomized liquid in the liquid storage cavity to the heating component in the atomizing component.

[0005] Optionally, the outer wall of the atomizing component is provided with a liquid inlet groove and a liquid inlet. The liquid inlet groove and the inner wall of the oil cup together form the liquid inlet channel, and the lower end of the liquid inlet channel is connected to the liquid inlet. An atomizing chamber is formed inside the atomizing component, and the heating component is disposed on one side of the atomizing chamber, including an oil guide body that is vertically or inclined and covers the liquid inlet, and a heating element that is attached to the side of the oil guide body facing the atomizing chamber.

[0006] Optionally, the angle between the liquid guiding slope and the bottom surface of the atomizing component is greater than 0° and less than 30°.

[0007] Optionally, the central axis of the inlet is perpendicular to the plane where the oil guide body is located.

[0008] Optionally, the inlet corresponds to the center of the oil guide body, and its cross-section is smaller than the side surface of the oil guide body.

[0009] Optionally, the atomizing assembly further includes a top assembly, which includes a bracket and a seal. The seal is fitted onto the upper end of the bracket and seals against the inner wall of the oil cup. The top surface of the seal is the liquid guiding slope, and the side wall is provided with a liquid inlet groove. The liquid inlet groove and the inner wall of the oil cup together form the liquid inlet channel, and the liquid inlet is located on the side wall of the bracket.

[0010] Optionally, the top assembly further includes an air duct, and the side of the bracket away from the liquid inlet is recessed to form a receiving space communicating with the liquid inlet. The heating element is vertically or inclinedly disposed on the side of the receiving space communicating with the liquid inlet. The air duct is installed in the receiving space and forms the atomizing chamber between it and the heating element.

[0011] Optionally, the air passage component also protrudes to form two abutment portions on the side facing the heating element, and the two abutment portions press the heating element tightly against the oil guide body.

[0012] Optionally, the atomizing assembly further includes a bottom assembly, which includes a base fixed to the bottom of the bracket and two electrodes extending from bottom to top through the base. The upper ends of the two electrodes extend into the receiving space, and the heating element is clamped between the two electrodes and the oil guide.

[0013] Optionally, the bottom assembly further includes a partition stacked on top of the base and located between the base and the bracket. The partition is a flat plate structure and forms an air intake channel with the base. The partition has an air vent that communicates with the air intake channel and the atomizing chamber respectively. The base is provided with an air intake vent that communicates with the air intake channel.

[0014] The atomizer of this invention uses a liquid-guiding slope on the top surface of the atomizing component that contacts the liquid storage chamber. This ensures that the upper port of the liquid inlet channel is located at the lowest point of the liquid-guiding slope. Therefore, even when there is a small amount of atomized liquid remaining in the liquid storage chamber, the atomizer can still smoothly flow into the liquid inlet channel under the action of gravity, even when the atomizer is slightly tilted. This guarantees the smooth flow of oil between the atomized liquid and the heating element, reducing the risk of coil clogging due to poor liquid guidance when the atomizer has less atomized liquid. As a result, the atomizer maintains a good atomization effect until the atomized liquid is completely used up, preserving the taste of the product. Attached Figure Description

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.

[0044] Please see Figure 1-3 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.

[0045] The atomizer 100 includes an oil cup 10 and an atomizing component 200. The atomizing component 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 lower end of the oil cup 10 is open, and the upper end is provided with an air inlet 11 for the user to inhale. An air guide tube 12 is formed on the inner wall of the end of the oil cup 10 where the air inlet 11 is located, extending into the interior of the oil cup 10 along the edge of the air inlet 11. 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 atomized liquid. In this embodiment, the air guide tube 12 and the oil cup 10 are integrally formed.

[0046] The atomizing component 200 has an atomizing chamber 231 inside. The atomizing component 200 includes a heating component 30 disposed on one side of the atomizing chamber 231. The heating component 30 includes a vertically disposed oil guide body 31 and a heating element 32 attached to the side of the oil guide body 31 facing the atomizing chamber 231. The outer wall of the atomizing component 200 is provided with a liquid inlet groove and a liquid inlet 212. The liquid inlet groove and the inner wall of the oil cup 10 together form a liquid inlet channel 222 communicating with the liquid storage chamber 13. The liquid inlet 212 provides the atomizing liquid in the liquid storage chamber 13 to the oil guide body 31 through the liquid inlet channel 222. The oil guide body 31 quickly conducts the absorbed atomizing liquid to contact the heating element 32.

[0047] The top surface of the atomizing component 200 that contacts the liquid storage chamber 13 is a liquid guiding slope 201. The upper port of the liquid inlet channel 222 is located at the lowest position of the liquid guiding slope 201. Thus, even when there is still a small amount of atomizing liquid remaining in the liquid storage chamber 13, the atomizer 100 can still flow smoothly into the liquid inlet channel 222 under the action of gravity, ensuring the smooth flow of oil between the atomizing liquid in the liquid storage chamber 13 and the heating element 32. This reduces the phenomenon of clogging the coil due to poor liquid guiding when the atomizer 100 has less atomizing liquid, so that the atomizer 100 can maintain a good atomization effect until the atomizing liquid is completely used up, thus maintaining the taste of the product.

[0048] Specifically, the angle A between the liquid guiding slope 201 and the bottom surface of the atomizing component 200 is greater than 0° and less than 30°, specifically 5°, 15°, and 25°, etc. In practical applications, it can be selected according to the flowability of different atomizing liquids. The worse the flowability of the atomizing liquid, the larger the angle between the liquid guiding slope 201 and the bottom surface of the atomizing component 200 should be, so as to ensure that the liquid guiding of the atomizing liquid is smooth even when the atomizer 100 is used under slight shaking. It should be understood that the bottom surface of the atomizing assembly is a plane perpendicular to the central axis of the atomizer.

[0049] To ensure better delivery of the atomizing liquid into the oil guide 31, the oil guide 31 is preferably at a 90° angle to the bottom surface of the atomizing assembly 200. In practical applications, the oil guide 31 can also be inclined, with the preferred angle between the oil guide 31 and the bottom surface of the atomizing assembly 200 ranging from 60° to 120°. It should be understood that the bottom surface of the atomizing assembly 200 is a plane perpendicular to the central axis of the atomizer 100.

[0050] Preferably, the central axis of the liquid inlet 212 is perpendicular to the plane where the oil guide body 31 is located, that is, the liquid inlet path of the atomizing liquid in the liquid inlet channel 222 and the liquid inlet 212 is L-shaped, so that the atomizing liquid can be introduced from the other side of the oil guide body 31 opposite to the heating element 32, which is conducive to the rapid and uniform distribution of the atomizing liquid in the oil guide body 31, and can then uniformly penetrate to the atomization surface of the oil guide body 31 on the side where the heating element 32 is located, so that the heating element 32 can perform heating and atomization more uniformly.

[0051] Furthermore, in this embodiment, the liquid inlet 212 corresponds to the center of the oil guide 31, thereby making the introduced atomizing liquid more evenly distributed on the oil guide 31 and enabling the atomizing liquid to be conducted to the central heating area of ​​the heating element 32 more quickly; wherein, the cross-section of the liquid inlet 212 is smaller than the side of the oil guide 31 to prevent the atomizing liquid from seeping out from the periphery of the oil guide 31. Preferably, the cross-sectional size of the liquid inlet 212 is approximately the same as that of the central heating area of ​​the heating element 32, so that the atomization effect of the heating element 32 is better.

[0052] The following is in conjunction with the appendix Figures 4 to 12 The structure of the atomizing component 200 in this embodiment will be further described in detail below. The atomizing component 200 includes a top component 20, a heating component 30, and a bottom component 40. It should be understood that the atomizer 100 of this embodiment is not limited to using a top component 20, a heating component 30, and a bottom component 40. Figures 4 to 12 The atomizing component 200 structure is shown.

[0053] 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 and Figure 8 As shown), the oil guide body 31 is a flat oil-absorbing cotton. The side of the cotton that is in contact with one side of the receiving space 211 is the liquid-absorbing surface, and the other side opposite to the liquid-absorbing surface is the atomizing surface. The heating element 32 is located on the atomizing surface of the oil guide body 31. The atomization volume of the oil-absorbing cotton is large, which makes the vaping experience better and the aroma reproduction of the atomized liquid is high.

[0054] The bottom assembly 40 includes a base 41 fixed to the bottom of the bracket 21 and two electrodes 42 extending from bottom to top through the base 41. The upper ends of the two electrodes 42 extend into the receiving space 211, so that the heating element 32 is held horizontally between the two electrodes 42 and the oil guide body 31. The two ends of the heating element 32 are electrically connected to the two electrodes 42 respectively. The air passage component 23 is preferably made of silicone material. It is sealed and installed in the receiving space 211 and forms an atomizing chamber 231 between itself and the heating assembly 30. One end of the atomizing chamber 231 is connected to the air intake channel 415 in the base 41, and the other end is connected to the air guide tube 12. The material of the air passage component 24 can also be plastic, metal or other materials. The specific material used can be selected according to the actual situation. This embodiment does not limit this.

[0055] A liquid inlet groove is provided on the side wall of the seal 22, thereby forming a liquid inlet channel 222 together with the inner wall of the oil cup. The upper end of the liquid inlet channel 222 is connected to the liquid storage chamber 13. The other side of the bracket 21 opposite to the receiving space 211 is provided with a liquid inlet 212. 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.

[0056] It should be understood that, in this embodiment, a notch communicating with the liquid inlet 212 may also be provided on the side wall of the bracket 21. The upper end of the notch extends through the top surface of the bracket 21. At this time, the liquid inlet groove on the seal 22 is a through groove that penetrates its inner and outer walls, thereby forming a liquid inlet channel 222 together with the notch, the liquid inlet through groove and the inner wall of the oil cup 10.

[0057] Preferably, to ensure the liquid inlet speed and prevent insufficient oil discharge speed of the oil guide 31 from causing the heating element 32 to burn, the width of the liquid inlet channel 222 is between 0.8 and 2 mm, the length is between 2 and 8 mm, and the cross-sectional area is between 1.6 and 15 mm². 2 between.

[0058] The heating element 32 is a metal sheet formed by etching conductive metal, such as nickel-chromium, iron-chromium-aluminum, or stainless steel, through etching or laser cutting. It includes two conductive parts 321 and a heating part 322 connected in series between the two conductive parts 321. The resistance of the conductive parts 321 is much smaller than that of the heating part 322, so that when the heating element 32 is energized, the conductive parts 321 generate only a small amount of heat, allowing the heat to be concentrated in the area of ​​the heating part 322 to ensure the atomization effect. In this embodiment, the shape of the heating part 322 is not particularly limited. For example, it can be grid-shaped, striped, S-shaped, zigzag-shaped, wavy, sawtooth-shaped, spiral, circular, or rectangular, as long as it can achieve planar heating.

[0059] The two conductive parts 321 are respectively welded and fixed to the same side of the two electrodes 42, such as... Figure 6 As shown, during assembly, the oil guide body 31 can be installed into the receiving space 211 first, and then the bottom assembly 40 with the heating element 32 welded on it can be fastened 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, as shown. Figure 8 As shown; then the air passage component 23 is sealed and installed into the receiving space 211, thereby forming the entire atomizing assembly 200, as shown. Figure 9 and Figure 10 As shown; 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, eliminating the need to bend and wrap the heating element 32. This solves the problem that the robotic arm is difficult to operate due to the softness of the oil guide body 31 and the heating element 32, enabling automated and batch assembly, improving production efficiency and reducing costs.

[0060] Of course, in other embodiments, the oil guide body 31 can also be a porous ceramic body. In this case, the heating element 32 can be embedded or brushed onto the atomizing surface of the oil guide body 31, thereby making the oil guide body 31 and the heating element 32 a whole. During assembly, the heating component 30 of the whole structure is first installed into the receiving space 211, and then the bottom component 40 is fastened and fixed to the bracket 21 in the horizontal direction, so that the upper ends of the two electrodes 42 are pressed and fixed to the conductive parts 321 at both ends of the heating element 32, realizing the electrical connection between the heating element 32 and the two electrodes 42. Such a structure can also realize automated and mass assembly.

[0061] In this embodiment, the top of the bracket 21 is provided with an air outlet 213 communicating with the atomizing chamber 231 and an annular groove 217 concentric with the air outlet 213. The sealing member 22 is provided with a sleeve part 223 having a sleeve hole 224. The lower end of the sleeve part 223 is sleeved in the annular groove 217 so that the sleeve hole 224 communicates with the air outlet 213. When the atomizing assembly 200 is inserted and assembled into the opening end 14 of the oil cup 10, the lower end of the air guide tube 12 is inserted into the sleeve hole 224 and sealed with the inner wall of the sleeve hole 224, thereby preventing the atomized liquid from seeping out from the gap between the air guide tube 12 and the sleeve hole 224 and causing leakage. This structure allows the air duct 12 to connect with the atomizing chamber 231 through the air outlet 213. When the user inhales into the air inlet 11, external air can enter the atomizing chamber 231 through the air inlet channel 415 in sequence. After mixing with the aerosol generated by the heating element 32, the air can be output through the air outlet 213, the air duct 12 and the air inlet 11 in sequence for the user to inhale.

[0062] It should be noted that the bottom periphery of the seal 22 has several first annular protrusions 221, and the liquid inlet groove is located above the several first annular protrusions 221. When the atomizing assembly 200 is inserted and assembled into the opening end 14 of the oil cup 10, the several first annular protrusions 221 elastically abut against the inner wall of the oil cup 10, thereby achieving a sealed connection between the seal 22 and the inner wall of the oil cup 10, so as to ensure the sealing of the liquid storage chamber 13, so that the atomizing liquid in the liquid storage chamber 13 can only flow out from the liquid inlet 212 into the oil guide body 31, and avoid leakage.

[0063] When the atomizer 100 is working, the atomizing liquid in the reservoir 13 is continuously introduced into the oil guide 31 and heated and atomized by the heating element 32 to form an aerosol. As the amount of atomizing liquid decreases, the internal air pressure in the reservoir 13 gradually decreases, eventually preventing the atomizing liquid from flowing smoothly into the oil guide 31. To solve the pressure problem in the reservoir 13, this embodiment provides a return air groove 214 on the side where the bracket 21 and the oil guide 31 are attached. The return air groove 214 and the oil guide 31 together form a return air channel. One end of the return air channel is connected to the liquid inlet 212, and the other end is connected to the atomization chamber 231. Preferably, the cross-sectional area of ​​the return air channel is 0.1-0.2 mm. 2 Thus, when the user inhales, the atomized liquid in the storage chamber 13 is absorbed and heated by the heating component 30, resulting in a negative pressure inside the storage chamber 13. While the external air mixes with the aerosol and is inhaled by the user, some of the gas can enter the storage chamber 13 from the formed return air channel and through the liquid inlet 212 and the liquid inlet channel 222, thereby balancing the air pressure inside the storage chamber 13 and avoiding poor oil flow.

[0064] In one embodiment, such as Figure 7 and Figure 8 As shown, the bracket 21 has vertical positioning slots 215 recessed on both sides of the receiving space 211. The two positioning slots 215 extend through the bottom of the bracket 21, and positioning blocks 216 protrude from the positioning slots 215. The base 41 has two positioning posts 413 protruding upward from both ends along its long axis. The two positioning posts 413 are provided with slots 414 that cooperate with the positioning blocks 216. The two positioning posts 413 are engaged in the two positioning slots 215 in the horizontal direction. The positioning blocks 216 are inserted into the slots 414 to fix the base 41 and the bracket 21 vertically. This allows the oil guide 31 and the heating element 32 to be clamped and fixed between the two electrodes 42 and one side of the receiving space 211, which facilitates automated assembly.

[0065] Furthermore, combined Figure 4 , Figure 5 and Figure 11 As shown, the bottom assembly 40 also includes a partition 43 stacked on top of the base 41 and located between the base 41 and the bracket 21. An air intake channel 415 is formed between the partition 43 and the base 41. The partition 43 has a first air passage 431 that communicates with the air intake channel 415 and the atomizing chamber 231 respectively. The bottom wall of the base 41 has an air intake hole 412 that communicates with the air intake channel 415. When the user inhales into the air inlet 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 first air passage 431. This structure facilitates the setting of the air intake hole 412, allowing the air intake hole 412 to be set at any position on the bottom of the base 41.

[0066] Specifically, the separator 43 is a flat plate structure made of silicone or rubber, which is sealed on the upper end of the base 41 and seals the lower end of the atomizing chamber 231. When the bottom component 40 is installed on the bracket 21 in the horizontal direction, the separator 43 is clamped between the bracket 21 and the base 41, and the upper and lower ends of the separator 43 elastically abut against the bracket 21 and the base 41 respectively, so that the bracket 21 and the base 41 are fixedly connected with a certain strength by the abutting force of the separator 43 in the vertical direction. This facilitates the subsequent installation of the air passage component 23 and the overall assembly of the atomizing component 200 into the oil cup 10. There is no need to use other fasteners to connect and fix the bracket 21 and the base 41, thus making it easy to achieve automated assembly.

[0067] Preferably, the peripheral wall of the separator 43 is formed with a plurality of second annular protrusions 433. When the atomizing assembly 200 is assembled into the opening end 14 of the oil cup 10, the plurality of second annular protrusions on the separator 43 elastically abut against the inner wall of the oil cup 10, further ensuring the sealing performance between the atomizing assembly 200 and the oil cup 10.

[0068] It should be noted that the cross-section of the oil cup 10 and the atomizing component 200 is approximately elliptical. The base 41 has two mounting channels 411 extending through its upper and lower ends. The two mounting channels 411 are symmetrically located at both ends of the base 41 along its long axis. The separator 43 has first through holes 434 at both ends corresponding to the positions of the two mounting channels 411. The two electrodes 42 are inserted into the two mounting channels 411 from bottom to top of the base 41. After the upper ends of the two electrodes 42 protrude from the two first through holes 434, the conductive parts 321 at both ends of the heating element 32 are welded and fixed to the upper side of the two electrodes 42. In addition, the separator 43 has second through holes 435 at both ends corresponding to the positions of the two positioning posts 413 along its long axis. When the separator 43 is fitted onto the top of the base 41, the upper ends of the two positioning posts 413 protrude from the two second through holes 435.

[0069] Specifically, in combination Figure 12 As shown, the air passage 23 protrudes from the side facing the heating element 30, forming two abutment portions 233. These two abutment portions 233 abut against the oil guide body 31 and press against the conductive portions 321 at both ends of the heating element 32, thereby making the heating element 32 more tightly attached to the atomizing surface of the oil guide body 31. The abutment portions 233 acting on the oil guide body 31 restrict the position of the air passage 23, facilitating automated assembly. Preferably, the two abutment portions 233 are located inside the two electrodes 42, thus using the air passage 23 and the heating element 30 to jointly form the atomizing chamber 231, and placing the two electrodes 42 outside the atomizing chamber 231 to prevent the generated aerosol from forming condensate on the electrodes 42.

[0070] In this embodiment, a second air passage 432 is also provided on the separator 43. The first air passage 431 and the second air passage 432 are symmetrically arranged at both ends of the separator 43 in the short axis direction. After the atomizing assembly 200 is assembled, one of the first air passage 431 and the second air passage 432 is blocked by the bracket 21, and the other is connected to the atomizing chamber 231. This allows the bottom assembly 40 to be assembled even after rotating 180° along its central axis, without needing to align the air passage of the bottom assembly 40 with the atomizing chamber 231 on the air passage component 23, making automated assembly more convenient. Preferably, in this embodiment, there are two first air passages 431 and two air passages 432, but there can also be one, three or more.

[0071] The specific assembly steps of the atomizer 100 of the present invention are as follows:

[0072] like Figure 4 As shown, two electrodes 42 are respectively installed into the two mounting channels 411 of the base 41. Then, the separator 43 is fitted onto the top of the base 41 so that the upper ends of the two electrodes 42 pass through the two first through holes 434 on the separator 43. The electrodes 42 are interference-fitted with the inner walls of the first through holes 434, thereby fixing the base 41, the separator 43, and the two electrodes 42 together to form the bottom assembly 40. Figure 5 As shown.

[0073] like Figure 6 As shown, the two conductive parts 321 of the heating element 32 are welded and fixed to the same side of the two electrodes 42, and the oil guide body 31 is installed in the receiving space 211 of the bracket 21, and the oil guide body 31 is tightly attached to the side surface with the liquid inlet 212, and the edge of the oil guide body 31 is interference-fitted with the inner wall of the receiving space 211.

[0074] like Figure 8 As shown, the bottom component 40 is fastened to the bracket 21 in the horizontal direction, so that the heating element 32 and the two electrodes 42 are pressed tightly onto the oil guide body 31.

[0075] like Figure 9 As shown, the air passage component 23 is assembled into the receiving space 211 of the bracket 21. At this time, an atomizing chamber 231 is formed between the heating component 30 and the air passage component 23. The first air passage 431 or the second air passage 432 on the separator 43 is connected to the atomizing chamber 231.

[0076] like Figure 13 and Figure 14 As shown, the sealing element 22 is fitted onto the top of the bracket 21, thereby completing the assembly of the atomizing component 200 and forming a whole.

[0077] Finally, the atomizing component 200 is installed into the open end 14 of the oil cup 10. At this time, the sealing component 22 and the separator 43 are sealed to the inner wall of the oil cup 10, and the base 41 is snapped to the oil cup 10, thus completing the assembly of the atomizer 100.

[0078] 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.

[0079] 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.
