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 e-liquid carrier, and then draw the aerosol out from the outlet inside the atomizer through suction. The atomized liquid in an electronic atomizer is contained in the e-liquid cup and flows to the e-liquid carrier through the lower e-liquid channel. Currently, the lower e-liquid channel in electronic atomizers is usually located inside the bracket, with the e-liquid carrier horizontally fixed at the bottom of the lower e-liquid channel and the heating element located on the lower surface of the e-liquid carrier. However, this structure requires the air passage between the atomization chamber and the e-liquid cup to bypass the e-liquid carrier from both sides, resulting in a relatively complex structure. 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 chamber with the oil cup. An atomizing chamber is formed inside the atomizing component. An air outlet is formed at the top of the atomizing component and communicates with the atomizing chamber. The atomizing component includes a heating component disposed on one side of the atomizing chamber. The heating component partially covers the air outlet along the thickness direction.

[0005] Optionally, the area of ​​the heating element covering the vent is less than 50% of the cross-sectional area of ​​the vent.

[0006] Optionally, the area of ​​the heating element covering the vent is 10-40% of the cross-sectional area of ​​the vent.

[0007] Optionally, the heating component includes an oil guide body that is vertically or inclinedly disposed and a heating element that is attached to the side of the oil guide body facing the atomizing chamber, wherein the middle part of the heating element is located in the area enclosed by the inner wall of the air outlet.

[0008] Optionally, the oil guide body is a flat plate structure, and the heating element is a sheet structure, including two conductive parts and a heating part connected in series between the two conductive parts, and the heating part is located in the area enclosed by the inner wall of the air outlet.

[0009] Optionally, the atomizing assembly further includes a top assembly, which includes a support and an air passage component. One side of the support is recessed to form a receiving space. The heating assembly is vertically or inclinedly disposed on one side of the receiving space. The air passage component is installed in the receiving space and forms the atomizing chamber between itself and the oil guide body.

[0010] Optionally, the top assembly further includes a seal, which is fitted onto the upper end of the bracket and sealed to the inner wall of the oil cup. The side wall of the seal has a liquid inlet groove, which together with the inner wall of the oil cup forms a liquid inlet channel communicating with the liquid storage chamber. The side wall of the bracket has a liquid inlet communicating with the liquid inlet channel. The liquid inlet provides the atomized liquid in the liquid storage chamber to the heating component through the liquid inlet channel.

[0011] 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.

[0012] 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.

[0013] 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.

[0014] The atomizer of this invention partially covers the lower end of the air outlet along the thickness direction with the heating element, so that the aerosol generated by the heating element can quickly and unobstructedly enter the air outlet. This is conducive to the full absorption of aerosol and avoids excessive contact between the high-temperature aerosol and the inner wall of the atomization chamber, which would generate a large amount of condensate. This reduces the formation of condensate and makes it less likely to accumulate, thereby reducing the chance of the user inhaling condensate during the inhalation process.

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.

[0038] Please see Figure 1-2 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.

[0039] 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.

[0040] The atomizing assembly 200 has an atomizing chamber 231 inside. The atomizing assembly 200 includes a heating element 30 disposed on one side of the atomizing chamber 231. The heating element 30 includes a vertically arranged oil guide 31 and a heating element 32 attached to the side of the oil guide 31 facing the atomizing chamber 231. That is, in this embodiment, the oil guide 31 is at a 90° angle to the bottom surface of the atomizing assembly 200. In practical applications, the oil guide 31 can also be inclined; preferably, the angle between the oil guide 31 and the bottom surface of the atomizing assembly 200 is in the range of 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.

[0041] The top of the atomizing component 200 has an air outlet 213 that communicates with the atomizing chamber 231. The upper end of the air outlet 213 is connected to the air guide tube 12. The oil guide body 31 partially covers the lower end of the air outlet 213 along the thickness direction. That is, along the central axis of the atomizer 100, the projection of the heating element 32 on the bottom surface of the atomizing component 200 intersects with the projection of the air outlet 213 on the bottom surface of the atomizing component 200. When the user inhales, the external air enters the atomizing chamber 231 and mixes with the aerosol generated by the heating element 32. It can then quickly and unobstructedly enter the air outlet 213 and be output through the air guide tube 12 and the inhalation port 11 for the user to inhale. This structure is conducive to the full inhalation of aerosol and avoids excessive contact between the high-temperature aerosol and the inner wall of the atomizing chamber 231, which would generate a large amount of condensate. This reduces the formation of condensate and makes it less likely for condensate to accumulate, thereby reducing the chance of the user inhaling condensate during inhalation.

[0042] In this embodiment, the area of ​​the oil guide 31 covering the air outlet 213 is less than 50% of the cross-sectional area of ​​the air outlet 213. That is, the intersection area of ​​the projections of the oil guide 31 and the air outlet 213 on the bottom surface of the atomizing component 200 forms a minor arc shape. Preferably, the intersection area is 10% to 40% of the cross-sectional area of ​​the air outlet 213. In specific settings, this intersection area can be 10%, 20%, 30%, or 40% of the cross-sectional area of ​​the air outlet 213. The specific intersection area can be determined based on the cross-sectional area of ​​the air outlet 213, as long as it ensures that the mixed airflow containing aerosol can quickly and unobstructedly enter the air outlet 213. Preferably, in this embodiment, the area of ​​the oil guide 31 covering the air outlet 213 is 10% of the cross-sectional area of ​​the air outlet 213, so that the aerosol can be fully carried away.

[0043] The following is in conjunction with the appendix Figures 3 to 8 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 3 to 8 The atomizing component 200 structure is shown.

[0044] 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 3 and Figure 4 As shown), the air outlet 213 is located at the top of the bracket 21 and communicates with the receiving space 211; the oil guide body 31 adopts a flat oil-absorbing cotton structure and is vertically installed on one side of the receiving space 211. The side of the oil guide body 31 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.

[0045] 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 inlet channel 415 in the base 41, and the other end is connected to the air guide tube 12 through the air outlet 213. 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.

[0046] 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. It includes two conductive parts 321 and a heating part 322 connected in series between the two conductive parts 321. The upper ends of the two electrodes 42 are electrically connected to the two conductive parts 321 respectively, and the two conductive parts 321 are pressed tightly against the atomizing surface of the oil guide body 31.

[0047] To facilitate the direct and rapid entry of the aerosol generated by the heating element 32 into the air outlet 213, the central portion of the heating part 322 of the heating element 32 is located within the area enclosed by the inner wall of the air outlet 213. It should be understood that the area enclosed by the inner wall of the air outlet 213 is the internal space formed by its extension along the axis of the atomizer 100; that is, the projection of the heating part 322 onto the bottom surface of the atomizing assembly 200 is within the projection range of the air outlet 213 onto the bottom surface of the atomizing assembly 200. This embodiment does not impose a particular limitation on the shape of the heating part 322; for example, it can be grid-like, striped, S-shaped, zigzag, wavy, sawtooth, spiral, circular, or rectangular, as long as planar heating can be achieved.

[0048] Specifically, the two conductive parts 321 can be welded and fixed to the same side of the two electrodes 42 respectively (e.g., Figure 5 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 3 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 6 and Figure 7 As shown; finally, the atomizing component 200 is inserted into the open end 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.

[0049] Combination Figure 8 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 press the conductive portions 321 at both ends of the heating element 32 tightly against the oil guide body 31, thereby making the heating element 32 more closely adhere to the atomizing surface of the oil guide body 31 and pressing both sides of the oil guide body 31 against the support 21 to prevent the atomized liquid from seeping out from the periphery of the oil guide body 31. Simultaneously, the abutment portions 233 also restrict the position of the air passage 23 by acting on the oil guide body 31, facilitating automated assembly. Preferably, the two abutment portions 233 are located inside the two electrodes 42, thus utilizing 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.

[0050] Combination Figure 7 As shown, 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.

[0051] 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 seal 22 and the inner wall of the oil cup 10.

[0052] 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.

[0053] Furthermore, combined Figure 2 As shown, the bottom component 40 also includes 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.

[0054] 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, 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.

[0055] 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 in other embodiments.

[0056] 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.
