Description

Technical Field

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

[0002] Currently, electronic atomizers all use a bottom-intake system, with the vapor exiting through a hole at the top. When the atomizer is working, the heating element of the coil heats up instantly, atomizing the e-liquid. To maximize atomization efficiency, the coil (which can be ceramic, cotton, or other heating elements) is typically laid flat, with the heating element perpendicular to the bottom air intake. The incoming air blows directly onto the heating element, quickly removing the vapor and maximizing the amount of vapor produced.

[0003] However, if an atomizer's structure, due to limitations in size or outer tube shape, or for better functionality and flavor, or for better assembly (such as automated assembly), requires the atomizer coil to be placed vertically, and the heating layer on the coil is not directly facing the air intake at the bottom of the atomizer, but rather at an angle or parallel to the air intake, then the external air entering from the bottom air intake cannot be blown vertically onto the heating layer. Instead, the airflow blows across the heating layer from the side, and the airflow direction is parallel to the arrangement of the heating layer, resulting in relatively low atomization efficiency. Summary of the Invention

[0004] The purpose of this invention is to at least partially address the shortcomings of the prior art and provide an atomizer.

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.

[0056] 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.

[0057] 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 atomizing component 200 includes a top component 20, a heating component 30 and a bottom component 40.

[0058] The oil cup 10 has an opening at its lower end and an air inlet 11 at its upper end 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 atomizing liquid. In this embodiment, the air guide tube 12 and the oil cup 10 are integrally formed.

[0059] 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 6 and Figure 7As shown, the heating element 30 includes an oil guide 31 vertically mounted on one side of the receiving space 211 and a heating element 32 attached to one side of the oil guide 31. The oil guide 31 is a flat oil-absorbing cotton, with the surface in contact with one side of the receiving space 211 being the liquid-absorbing surface and the opposite side being the atomizing surface. The heating element 32 is located on the atomizing surface of the oil guide 31. The use of oil-absorbing 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 31 is at a 90° angle to the bottom surface of the atomizing element 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 element 200 is in the range of 60° to 120°. It should be understood that the bottom surface of the atomizing element 200 is a plane perpendicular to the central axis of the atomizer 100.

[0060] The air passage component 23 is preferably made of silicone material. It is sealed and installed in the receiving space 211, forming an atomizing chamber 231 between itself and the heating element 30. One end of the atomizing chamber 231 is connected to the air intake channel 415 in the bottom component 40, and the other end is connected to the air guide tube 12. The cross-sectional area of ​​the atomizing chamber 231 gradually expands from the position corresponding to the middle of the heating element 32 towards the air intake channel 415. Thus, when the user inhales, due to the gradual change in the cross-sectional area of ​​the atomizing chamber 231, the airflow velocity is minimized when it first enters the atomizing chamber 231 from the air intake channel 415, and reaches its maximum velocity when it passes the high-temperature position in the middle of the heating element 231. This facilitates the faster removal of the aerosol generated by the heating element 32, maximizing atomization efficiency.

[0061] Specifically, the inner side of the air duct 23 opposite to the heating element 30 includes a first guide surface 232. The distance between the first guide surface 232 and the heating element gradually increases from the upper end corresponding to the middle of the heating element 30 to the lower end. The first guide surface 232 is used to limit the flow direction of the intake airflow in the atomizing chamber 231, thereby achieving a gradual change in the cross-sectional area of ​​the atomizing chamber 231 along the flow direction of the airflow. After the external airflow enters the atomizing chamber 231 through the intake channel 415, it is guided by the blocking effect of the first guide surface 232 and blown towards the high-temperature position in the middle of the heating element 32, so as to better remove the aerosol generated on the surface of the heating element 32. Preferably, the angle between the first guide surface 232 and the plane where the heating element 30 is located is 30 to 90°, and the specific angle can be adjusted comprehensively according to the intake volume, heating power and other factors.

[0062] Furthermore, the inner side of the air passage 23 opposite to the heating element 30 also includes a second guide surface 234 connected to the first guide surface 232 at its lower end. The distance between the second guide surface 234 and the heating element 30 gradually increases from the lower end to the upper end. That is to say, the cross-sectional area of ​​the atomizing chamber 231 is a structure with large upper and lower ends and small middle, and its cross-sectional area is the smallest at the connection between the first guide surface 232 and the second guide surface 234. Since the aerosol generated by the airflow after passing through the heating element 32 will produce condensate on the inner wall of the atomizing chamber 231, if the cross-sectional area of ​​the end of the atomizing chamber 231 connected to the air outlet 213 is small, it is easy to be blocked by the accumulation of condensate, resulting in the phenomenon that the mixed gas during inhalation carries condensate, thereby affecting the taste. Therefore, the atomizing chamber 231 in this embodiment adopts a structure that is small in the middle and large at both ends, so that the condensate is not easy to accumulate at the end where the atomizing chamber 231 is connected to the air outlet 213, thus avoiding the phenomenon of condensate blocking the air outlet of the atomizing chamber 231 and causing oil splattering.

[0063] To ensure smoother airflow through the atomizing chamber 231, the first guide surface 232 and the second guide surface 234 are connected by a rounded transition. Furthermore, to guarantee sufficient airflow velocity at the junction of the first guide surface 232 and the second guide surface 234 while also achieving a large atomization volume, the cross-sectional area at this junction is 2.5–7.0 mm². 2 It should be understood that 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, and this embodiment does not limit it.

[0064] 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 at least partially 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 intake channel 415 in the base 41, and the other end is connected to the air guide tube 12.

[0065] 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. 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.

[0066] 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.

[0067] Preferably, to ensure the liquid inlet speed and prevent insufficient oil guiding speed of the oil guide body 31 from causing the heating element 32 to burn out, 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.

[0068] 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.

[0069] The two conductive parts 321 are respectively welded and fixed to the same side of the two electrodes 42, such as 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 7 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 8 and Figure 9 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.

[0070] 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 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. Such a structure can also realize automated and mass assembly.

[0071] 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 channel 415 and the atomizing chamber 231 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 inhalation port 11 in sequence for the user to inhale.

[0072] 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 annular protrusions 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.

[0073] In this embodiment, when the atomizing liquid is in operation, the atomizing liquid in the storage chamber 13 is continuously introduced into the oil guide body 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 storage chamber 13 gradually decreases, eventually preventing the atomizing liquid from flowing smoothly into the oil guide body 31. To solve the pressure problem in the storage chamber 13, this embodiment provides a return air groove 214 on the side where the support 21 and the oil guide body 31 are attached. The return air groove 214 and the oil guide body 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 atomizing 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.

[0074] In one embodiment, such as Figure 6 and Figure 7 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.

[0075] Furthermore, combined Figure 3 , Figure 4 and Figure 10As 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.

[0076] Preferably, the central axis of the first air passage 431 is parallel to the central axis of the atomizer 100 and corresponds to the side of the atomizing chamber 231 away from the heating element 30. That is, the projection of the first air passage 431 connecting the atomizing chamber 231 and the air inlet channel 415 along its axial direction is located within the range of the first guide surface 232 and is located at the position of the first guide surface 232 away from the heating element 30. In this way, when the external airflow enters the atomizing chamber 231 from the air inlet channel 415 through the air passage, it is first blocked by the first guide surface 232 and turned to be blown obliquely onto the heating element 32, so as to avoid the airflow entering the atomizing chamber 231 through the air passage directly passing through the narrowest part of the atomizing chamber 231 and affecting the atomization efficiency.

[0077] 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.

[0078] 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.

[0079] It should be noted that the cross-sections of the oil cup 10 and the atomizing component 200 are 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. 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.

[0080] Specifically, in combination Figure 11 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. 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 utilizing the air passage 23 and the heating element 30 to jointly form an atomization chamber 231, and placing the two electrodes 42 outside the atomization chamber 231 to prevent the generated aerosol from forming condensate on the electrodes 42. In other words, the first guide surface 232 and the second guide surface 234 are located between the two abutment portions 233.

[0081] Preferably, the separator 43 is further provided with a second air passage 432. 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, one of the first air passage 431 and the second air passage 432 is blocked by the bracket 21 and becomes inactive, while the other communicates with 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, the number of the first air passage 431 and the second air passage 432 is two, but it can also be one, three, or more.

[0082] It should be understood that in this embodiment, the base 41 and the air passage component 23 can adopt an integral molding structure, which can further optimize the overall structure of the atomizer 100; or during assembly, the air passage component 23 can be fixed on the bottom component 40 first, and then the bottom component 40 and the top component 30 can be assembled to form the atomizing component 200 as a whole.

[0083] The specific assembly steps of the atomizer 100 of the present invention are as follows:

[0084] like Figure 3 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 4 As shown.

[0085] like Figure 5 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.

[0086] like Figure 7 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.

[0087] like Figure 8 As shown, the air passage 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 23. The first air passage 431 or the second air passage 432 on the separator 43 is connected to the first air passage 232a of the atomizing chamber 231.

[0088] 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.

[0089] Atomizing liquid is injected into the liquid storage chamber 13 of the oil cup 10 through the open end 14. Then, 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 and fixed to the oil cup 10, thus completing the assembly of the atomizer 100.

[0091] 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.
