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. An internal receiving space is formed within the atomizing component. The atomizing component includes a heating element and an air passage component. The air passage component is installed within the receiving space, and protrudes from one side towards the heating element, forming two abutment portions. The two abutment portions respectively press the support portions on both sides of the heating element tightly against the oil guide body, forming an atomizing chamber between the air passage component and the oil guide body. The heating element is located within the atomizing chamber. This invention utilizes the air passage component to press the heating element tightly against the oil guide body, maintaining a certain pressure to press the oil guide body against the side wall of the receiving space. This ensures that no leakage occurs between the oil guide body and the side wall of the receiving space, and compresses the cotton-structured oil guide body to an appropriate tightness, allowing the oil guide body to have a suitable oil delivery speed for optimal atomization, while preventing deformation of the heating element.

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 atomizing liquid absorbed by the oil guide, and then draw the aerosol out from the air outlet inside the atomizer through suction.

[0003] Existing electronic atomizers can be broadly categorized into two types based on their heating and atomizing components: flat ceramic coils and cotton wicks with heating wires. Each type has its advantages: the cotton wick and heating wire structure offers advantages such as thorough atomization, high atomization volume, high flavor fidelity, strong throat hit, and good taste. However, this structure requires a tight fit between the heating wire and the cotton wick for optimal atomization. The heating wire is relatively thin and prone to deformation and warping, making it difficult to achieve a tight fit with the wick. This makes automated assembly challenging for robotic arms, hindering production automation and significantly reducing efficiency.

[0004] In addition, the function of the cotton wick is to use its oil-conducting properties to conduct the atomized liquid to the heating wire. In actual use, it must maintain a certain tightness; if it is too loose, the oil will be conducted too quickly, and if it is too tight, the oil will be conducted too slowly, and it is easy to deform the thin heating wire. Therefore, too fast or too slow will affect the atomization effect of the heating wire.

[0005] The planar heating ceramic core is made by printing a metal film or attaching an etched metal sheet on a ceramic heating element. The heating element is horizontally positioned, and the conductive parts at both ends of the heating element are held and fixed only by the top of the two electrodes. This makes the middle part of the heating element prone to deformation and separation from the ceramic body or stress cracking, resulting in the heating element burning and scorching. Summary of the Invention

[0006] The purpose of this invention is to at least partially address the shortcomings of the prior art and provide an atomizer.

[0007] 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 interior of the atomizing component forms a receiving space. The atomizing component includes a heating component and an air passage component. The heating component includes an oil guide body vertically or inclinedly disposed on one side of the receiving space and a heating element attached to the side of the oil guide body facing the receiving space. The heating element includes a heating part and at least one support part extending from both sides of the heating part. The air passage component is installed in the receiving space, and two abutting parts protrude from the side facing the heating component. The two abutting parts respectively press the support parts on both sides of the heating part tightly against the oil guide body, and an atomizing cavity is formed between the air passage component and the oil guide body. The heating part is located in the atomizing cavity.

[0008] Optionally, the oil guide body is a flat plate structure, the heating element is a sheet structure, and it also includes two conductive parts extending along both sides respectively. The two conductive parts extend out of the opposite outer sides of the two supporting parts and are electrically connected to the two electrodes respectively.

[0009] Optionally, the distance between the two supporting portions on their inner sides is greater than the width of the heating portion in the lateral direction, but less than the distance between the ends of the supporting portions on both sides of the heating element.

[0010] Optionally, the distance between the two abutting portions on their opposite outer sides is greater than the distance between the ends of the supporting portions on both sides of the heating element.

[0011] Optionally, the atomizing assembly further includes a top assembly, which includes a bracket and a seal. The bracket is sealed to the inner wall of the oil cup via the seal, and the receiving space is formed by a recess on one side of the bracket.

[0012] Optionally, the atomizing assembly further includes a bottom assembly, which includes a base fixed to the bottom of the bracket and two electrodes inserted from bottom to top in the base. The upper ends of the two electrodes extend into the receiving space and press the two electrodes tightly against the oil guide body.

[0013] Optionally, the two electrodes are located on opposite sides of the two abutment portions.

[0014] Optionally, the two conductive parts of the heating element are welded and fixed to the same side of the two electrodes.

[0015] Optionally, the bracket has vertical positioning slots recessed on both sides of the receiving space, and the two positioning slots extend through the bottom of the bracket, with positioning blocks protruding from the positioning slots; the base has two positioning posts protruding upward from both ends, and each of the two positioning posts has a slot that mates with the positioning blocks; the two positioning posts are engaged horizontally in the two positioning slots, and the positioning blocks are engaged in the slots to fix the base and the bracket vertically.

[0016] 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.

[0017] This invention relates to an atomizer designed for vertically or inclined heating elements. It utilizes an air passage to press the heating element firmly against the oil guide body and maintains a certain pressure to press the oil guide body against the side wall of the receiving space. This ensures that no leakage occurs between the oil guide body and the side wall of the receiving space, and compresses the cotton-structured oil guide body to an appropriate tightness so that the oil guide body has a suitable oil guiding speed to achieve the best atomization effect, while preventing the heating element from being deformed.

In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0046] Please see Figure 1-4 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] 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.

[0048] The atomizing assembly 200 has an internal receiving space 211. The atomizing assembly 200 includes a heating assembly 30 and an air passage component 23. The heating assembly 30 includes an oil guide 31 vertically or inclinedly disposed on one side of the receiving space 211 and a heating element 32 attached to the side of the oil guide 31 facing the receiving space 211. The heating element 32 includes a heating part 322 and at least one support part 323 extending from both sides of the heating part 322. Figure 7 (As shown); the air passage component 23 is installed in the receiving space 211, and two supporting parts 233 protrude from the side facing the heating component 30. The two 233 press the supporting parts 323 on both sides of the heating part 322 tightly against the oil guide body 31, and an atomization chamber 231 is formed between the oil guide body 31 and the oil guide body 31. The heating part 322 is located in the atomization chamber 231. The oil guide body 31 can absorb the atomized liquid stored in the liquid storage chamber 13 through the liquid inlet channel and guide the atomized liquid to contact the heating element 32. When the heating element 32 is energized and heated, it heats and atomizes the contacted atomized liquid to generate an inhalable aerosol in the atomization chamber 231.

[0049] According to the atomizer of this embodiment, when the atomizing component 200 is assembled into the oil cup, the outer side of the air passage component 23 abuts against the inner wall of the oil cup, so that the two supporting parts 233 of the air passage component 23 press the heating element 32 tightly against the oil guide body 31, and maintain a certain pressure to press the oil guide body 31 tightly against the side wall of the receiving space 211, so as to ensure that no leakage occurs between the oil guide body 31 and the side wall of the receiving space 211.

[0050] In this embodiment, the oil guide 31 is preferably made of oil-absorbing cotton. This structure allows the oil-absorbing cotton to be compressed to an appropriate tightness after assembly of the air passage 23, so that the oil guide 31 has a suitable oil guiding speed to obtain the best atomization effect, while preventing the heating element 32 from being deformed. In actual production, experiments can be conducted using air passage 23 with different protrusion heights of the supporting portion 233.

[0051] The heating element 32 has a sheet-like structure and includes two conductive portions 321 extending along both sides. The two conductive portions 321 extend from the opposite outer sides of the two supporting portions 233 and are electrically connected to the two electrodes. Specifically, in this embodiment, the two electrodes of the atomizing assembly 200 directly contact the two conductive portions 321, pressing the two conductive portions 321 tightly against the oil guide body 31 to facilitate automated assembly. Of course, in other embodiments, the conductive portions 321 can also be electrically connected to the electrodes by adding conductive pins.

[0052] Furthermore, the distance between the inner sides of the two supporting portions 233 is greater than the transverse width of the heating element 322, but less than the distance between the ends of the supporting portions 323 on both sides of the heating element 32. In other words, the supporting portion 233 of the air passage component 23 only contacts the supporting portion 323 of the heating element 32, and does not contact the heating element 322 itself. This prevents the heat generated by the heating element 322 from being directly conducted to the supporting portion 233 when the heating element 32 is energized, reducing heat loss and preventing the atomizer's outer shell from becoming too hot to handle. Additionally, the distance between the outer sides of the two supporting portions 233 is greater than the distance between the ends of the supporting portions 323 on both sides of the heating element 32. That is, the ends of the supporting portions 323 do not extend beyond the outer side of the supporting portions 233, thus preventing electrical connection between the electrode and the supporting portion 323 and ensuring the heating efficiency of the heating element 322.

[0053] The following is in conjunction with the appendix Figures 5 to 11 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 5 to 11 The atomizing component 200 structure is shown.

[0054] 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 8 and Figure 9As shown, the oil guide body 31 is flat, with the side that fits against one side of the receiving space 211 serving as the liquid-absorbing surface, and the opposite side serving as the atomizing surface. The heating element 32 is disposed on the atomizing surface of the oil guide body 31. The use of absorbent cotton results in a large atomization volume, providing a good vaping experience and high flavor reproduction of the atomized liquid. In this embodiment, the oil guide body 31 is at a 90° angle to the bottom surface of the atomizing component 200. In practical applications, the oil guide body 31 can also be inclined, preferably with an angle between 60° and 120° between the oil guide body 31 and the bottom surface of the atomizing component 200. It should be understood that the bottom surface of the atomizing component 200 is a plane perpendicular to the central axis of the atomizer 100.

[0055] 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 conductive parts 321 at both 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 at least partially 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 inlet chamber 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.

[0056] A liquid inlet groove is provided on the side wall of the seal 22. The liquid inlet groove and the inner wall of the oil cup 10 together form a liquid inlet channel 222. 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 of 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.

[0057] Optionally, in this embodiment, the side wall of the bracket 21 may also have a notch corresponding to the liquid inlet groove of the seal 22, which communicates with the liquid inlet 212. The upper end of the notch extends through the top surface of the bracket 21, thereby forming a liquid inlet channel 222 together with the liquid inlet groove and the inner wall of the oil cup 10.

[0058] 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.

[0059] 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. The resistance of its conductive portion 321 is much lower than that of the heating portion 322. Therefore, when the heating element 32 is energized, the conductive portion 321 generates only a small amount of heat, concentrating the heat in the heating portion 322 area to ensure atomization. This embodiment does not impose a particular limitation on the shape of the heating portion 322; for example, it can be grid-like, striped, S-shaped, zigzag, wavy, sawtooth, spiral, circular, or rectangular, as long as planar heating is achieved.

[0060] The two conductive parts 321 are respectively welded or riveted to the same side of the two electrodes 42, such as Figure 7 As shown, during assembly, the oil guide body 31 can be installed into the receiving space 211 first, and then the bottom component 40, on which the heating element 32 is fixed, can be snapped and fixed onto 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 9 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 10 and Figure 11 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 all components to be assembled using a vertical or horizontal stacking method, eliminating the need to bend or wrap the heating element 32. This solves the problem of the robotic arm being 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. It should be noted that after assembly, the air passage component 23 also presses down on two electrodes 42 to ensure they are in close contact with the two conductive parts 321 of the heating element 32, achieving electrical connection.

[0061] 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 forming an integral unit between the oil guide body 31 and the heating element 32. During assembly, the heating component 30 of the integral 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 or welded 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. Then, the air passage component 23 is sealed and installed in the receiving space 211, and the two supporting parts 233 are pressed against the supporting parts 323 and conductive parts 321 on both sides of the heating part 323 to press the ceramic oil guide body with the heating element tightly, so as to ensure the sealing performance between the oil guide body 31 and the bracket 21. Such a structure can also realize automated and mass assembly.

[0062] 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 through the inhalation port 11, external air can enter the atomizing chamber 231 through the air inlet 415 and mix with the aerosol generated by the heating element 32. The mixture can then be output through the air outlet 213, the air duct 12, and the inhalation port 11 for the user to inhale.

[0063] 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.

[0064] 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.

[0065] In one embodiment, such as Figure 8 and Figure 9 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.

[0066] Furthermore, combined Figure 5 , Figure 6 and Figure 11As 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 chamber 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 chamber 415 and the atomizing chamber 231 respectively. The top surface of the base 41 is recessed to form an accommodating space. The partition 43 is fitted and fixed to the top of the base 41 and covers the accommodating space to form the air intake chamber 415. The base 41 has an air intake pipe protruding upward from the bottom surface of the accommodating space. The air intake pipe has a connection with the air intake chamber 41. 5. A connected air inlet 412; when the user draws air into the inlet 11, the outside air first enters the air inlet chamber 415 between the separator 43 and the base 41, and then enters the atomizing chamber 231 through the first air passage 431; in this way, without affecting the normal air intake function of the atomizer, the air inlet chamber 415 is used to collect and store condensate or atomized liquid that leaks due to poor sealing, and the air inlet 412 can be conveniently set, so that the air inlet 412 can be set at any position on the bottom of the base 41 to ensure that the air inlet 412 and the first air passage 431 are misaligned.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] Furthermore, a second air passage 432 can be 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. When the atomizing assembly 200 is assembled, the second air passage 432 is blocked by the bracket 21 and does not function. Only the first air passage 431 connects the air intake chamber 415 and the atomizing chamber 231. In this way, the bottom assembly 40 can still be assembled after rotating 180° along its central axis. At this time, the first air passage 431 is blocked by the bracket 21 and does not function. Only the second air passage 432 connects the air intake chamber 415 and the atomizing chamber 231. That is to say, it is not necessary to align the air passage of the bottom assembly 40 with the atomizing chamber 231 on the air passage 23, which makes automated assembly more convenient. Preferably, in this embodiment, there are two first air passages 431 and two air passages 432. Of course, 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 5 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 6 As shown.

[0073] like Figure 7As 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 9 As shown, the bottom component 40 is fastened to the bracket 21 in a 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 10 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 12 and Figure 13 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] Install the atomizing component 200 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 to complete 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.
