Description

Technical Field

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

[0002] Regardless of whether an atomizer uses a ceramic heating element or a cotton wick heating element, its overall thickness cannot be made very thin due to limitations in the internal heating element structure, atomization chamber size, and airflow channel structure.

[0003] Because the atomizer is too thin, the size of the internal components must be compressed. The size of these internal components directly affects the atomizer's performance in terms of air exchange, e-liquid sealing, e-liquid dispensing, atomization, air intake, air exhaust, and sealing. Simply reducing the size of the atomizer's components does not guarantee its performance.

[0004] In related technologies, atomizers typically consist of an oil cup and an atomizing component. The oil cup has an airflow tube, and the atomizing component contains an atomization chamber. An airflow channel connects the atomization chamber and the airflow tube. However, when the thickness of the atomizer decreases, if the technical solution in these technologies is adopted, the airflow channel's smoothness will be affected by the drastically reduced cross-sectional size. Aerosols are prone to condensing at the airflow channel, impacting the user experience. Summary of the Invention

[0020] Furthermore, a first liquid discharge channel is provided at the top of the support, and a second liquid discharge channel is formed inside the support, which is connected to the first liquid discharge channel and is in contact with the liquid absorption surface.

[0047] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. 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.

[0048] In this embodiment, combined with Figures 1-6This invention provides an atomizing component 100, which is used to assemble one end of an oil cup 200 to form an atomizer. The atomizing component 100 includes a support 1, an oil guide 2 and a heating element 3 vertically or inclinedly disposed inside the support 1, and a sealing element 4 assembled at the top of the support 1. The oil guide 2 and the heating element 3 are respectively flat and sheet-shaped. The oil guide 2 can be made of porous ceramic or oil-guiding cotton, etc., and the heating element 3 can be formed by etching a metal sheet. The oil guide 2 has a liquid absorption surface and an atomizing surface, and the heating element 3 is disposed on the oil guide 2. On the atomizing surface of the oil body 2, an atomizing chamber 10 is formed in the atomizing component 100 located on one side of the atomizing surface; the support 1 is provided with a ventilation groove 11, and a first guide surface 111 is provided at the bottom of the ventilation groove 11; the sealing member 4 is provided with a second guide surface 4111 opposite to the first guide surface 111; both the first guide surface 111 and the second guide surface 4111 are inclined toward the central axis of the atomizing component 100; the first guide surface 111 and the second guide surface 4111 enclose and form an air outlet channel 20 that connects to the atomizing chamber 10.

[0049] In this design, the atomizing liquid is heated and atomized in the atomizing chamber 10 by the heating element 3 after passing through the oil guide body 2. The outside atmosphere enters the atomizing chamber 10 and mixes with the atomized liquid to form an aerosol. The air outlet channel 20 connects to the atomizing chamber 10. The air outlet channel 20 is formed by the first guide surface 111 provided on the ventilation groove 11 and the second guide surface 4111 provided on the sealing element 4. Since the first guide surface 111 and the second guide surface 4111 are both inclined towards the central axis of the atomizing component 100, the cross-sectional size of the air outlet channel 20 is less affected by the thickness direction of the atomizing component 100 and can be designed to be larger, thereby making the aerosol air outlet smoother and reducing the accumulation of condensate.

[0050] Furthermore, the included angle between the first guide surface 111 and the second guide surface 4111 is 0-20°. This setting allows the distance between the first guide surface 111 and the second guide surface 4111 to remain approximately the same. Even with a smaller thickness of the atomizing component 100, the cross-sectional area of ​​the air outlet channel 20 does not change significantly. This allows the aerosol in the atomizing chamber 10 to be discharged more smoothly through the air outlet channel 20, and makes it less likely for condensate to accumulate at the air outlet channel 20.

[0051] Preferably, the angle between the first guide surface 111 and the central axis of the atomizing component 100 is 30-75°. In this embodiment, the angle between the second guide surface 4111 and the central axis of the atomizing component 100 is also 30-75°, that is, the extending directions of the first guide surface 111 and the second guide surface 4111 are approximately the same, and the angle between the first guide surface 111 and / or the second guide surface 4111 and the central axis of the atomizing component 100 can be 35°, 45°, 55°, 65°, etc. It should be understood that when the included angle between the first guide surface 111 and the second guide surface 4111 is 0-20°, the first guide surface 111 and the second guide surface 4111 can be arranged in three main ways: In the first arrangement, the first guide surface 111 and the second guide surface 4111 are parallel to each other, therefore, the distance between the first guide surface 111 and the second guide surface 4111 is consistent; In the second arrangement, the included angle between the first guide surface 111 and the central axis of the atomizing assembly 100 can be greater than that between the second guide surface 4111 and the second guide surface 4111. The angle between the first guide surface 111 and the central axis of the atomizing component 100 is such that the distance between the first guide surface 111 and the second guide surface 4111 gradually increases along the airflow direction, resulting in better airflow passage 20. In the third configuration, the angle between the first guide surface 111 and the central axis of the atomizing component 100 can be smaller than the angle between the second guide surface 4111 and the central axis of the atomizing component 100. In this configuration, the distance between the first guide surface 111 and the second guide surface 4111 gradually decreases along the airflow direction.

[0052] Furthermore, in this embodiment, the first guide surface 111 is a plane, and the second guide surface 4111 is also a plane. Using planes can ensure smoother gas flow and less condensate buildup.

[0053] In some embodiments, the first guide surface 111 and / or the second guide surface 4111 may also be curved surfaces. When the first guide surface 111 is curved, the tangent plane at each point of the first guide surface 111 is parallel or intersects the extension surface of the second guide surface 4111; when the second guide surface 4111 is curved, the tangent plane at each point of the second guide surface 4111 is parallel or intersects the extension surface of the first guide surface 111. The first guide surface 111 and / or the second guide surface 4111 can be convex or concave. By setting the surface as curved, when the aerosol in the atomizing chamber 10 flows through the air outlet channel 20, the aerosol turns more gently, thus the flow is smoother and less prone to condensation.

[0054] Furthermore, the top of the seal 4 is provided with a through air guide hole 412, the air guide hole 412 and the air groove 11 are positioned correspondingly, and the bottom side of the seal 4 is provided with a guide block 411 located at the edge of the air guide hole 412, and the second guide surface 4111 is provided on the guide block 411; the groove opening of the air groove 11 matches the guide block 411, the guide block 411 is embedded in the groove opening of the air groove 11, and the guide block 411 and the air groove 11 together form a through hole.

[0055] Specifically, the air guide hole 412 on the seal 4 is used to connect and cooperate with the air guide tube of the oil cup 200. It is combined with the flow guide block 411 and the air groove 11 to form a complete through hole, which can ensure that the airflow flows normally to the air guide hole 412. At the same time, the fit between the seal 4 and the bracket 1 is tighter, ensuring the reliability of the atomizing assembly 100. In addition, compared with the conventional solution of opening a through hole with closed side wall on the bracket 1 and the seal 4 being sleeved on the outside of the bracket 1, it saves materials and can reduce the size of the atomizing assembly 100 in the thickness direction.

[0056] Furthermore, in this solution, the ventilation groove 11 is U-shaped. In some embodiments, the ventilation groove 11 can also be C-shaped, ︺-shaped, ﹀-shaped, [-shaped, etc., as long as there is a notch on one side. It should be understood that the shape of the guide block 411 can be adapted to the shape of the ventilation groove 11, as long as it can match the notch of the ventilation groove 11 and form a through hole with the ventilation groove 11.

[0057] Furthermore, the atomizing chamber 10 is offset to one side of the central axis of the atomizing assembly 100. The air guide hole 412 is coaxial with the central axis of the atomizing assembly 100, and the same ends of the first guide surface 111 and the second guide surface 4111 are both connected to the wall of the air guide hole 412. By setting the atomizing chamber 10 to one side of the central axis of the atomizing assembly 100, compared with the prior art scheme where the atomizing chamber 10 is set at the central axis of the atomizing assembly 100, the distance between the atomizing chamber 10 and the outer surface of the atomizing assembly 100 is smaller, saving materials. Moreover, it can free up space on the other side of the central axis of the atomizing assembly 100 to set other structures, improving the space utilization rate within the atomizing assembly 100. With this arrangement, the thickness of the atomizing assembly 100 can be made thinner while ensuring the normal function of the atomizing assembly 100.

[0058] Furthermore, a mounting groove 12 communicating with the ventilation groove 11 is provided on one side of the bracket 1, and the oil guide 2 is attached to the bottom of the mounting groove 12; the atomizing assembly 100 also includes an air passage component 5 embedded in the opening of the mounting groove 12, and the oil guide 2 and the air passage component 5 together form an atomizing chamber 10. Specifically, the mounting groove 12 is a square groove with an oil guide hole at the bottom. The oil guide body 2 covers the oil guide hole. The mounting groove 12 has an opening at the bottom of the bracket 1. Furthermore, a protruding limiting protrusion is provided at the bottom edge of the mounting groove 12. The limiting protrusion abuts against the bottom edge of the oil guide body 2, thereby ensuring that the oil guide body 2 is accurately positioned and firmly assembled. The air passage component 5 has a groove with two through-holes on the side near the oil guide body 2. The groove and the atomizing surface of the oil guide body 2 together form the atomizing chamber 10. When the air passage component 5 is assembled in the mounting groove 12, it can abut against the side of the heating element 3 away from the oil guide body 2, thereby abutting and adhering the heating element 3 to the oil guide body 2. The oil guide body 2 is not easily warped or deformed, which can ensure the reliability of atomization.

[0059] Furthermore, the first guide surface 111 is connected to the edge of the atomizing surface, and the air passage component 5 is provided with a third guide surface 51 with one end connected to the side of the cavity wall of the atomizing cavity 10 away from the atomizing surface; the other end of the third guide surface 51 faces the second guide surface 4111 and is inclined in a direction away from the atomizing surface. Specifically, the air passage component 5 is preferably made of elastic materials such as silicone, so as to form a good sealing and fixing effect with the inner wall of the mounting groove 12. The close ends of the third guide surface 51 and the second guide surface 4111 both extend away from the atomizing surface, that is, away from the central axis of the atomizing component 100. Therefore, a clearance cavity is formed between the second guide surface 4111 and the third guide surface 51. The clearance cavity serves as part of the air outlet channel 20. Thus, the cross-sectional area at the junction of the air outlet channel 20 and the atomizing chamber 10 is larger than the cross-sectional area of ​​the atomizing chamber 10. The aerosol flows out of the atomizing chamber 10 more smoothly, which can prevent the aerosol from forming condensate during the air outlet process and improve the user experience.

[0060] In this embodiment, a clearance opening is formed between the guide block 411 and the air passage component 5. When the atomizing component 100 is assembled inside the oil cup 200, the inner wall of the oil cup 200 covers the clearance opening. Therefore, the inner wall of the oil cup 200 can serve as part of the inner wall of the air outlet channel 20. Compared with the related art where the air outlet channel 20 is completely located inside the atomizing component 100, this solution saves materials and effectively utilizes the cooperation relationship between the seal 4, the bracket 1, and the oil cup 200 to form a clearance cavity. Within the limited volume of the atomizing component 100, the cross-sectional area of ​​the air outlet channel 20 is increased, thereby reducing condensation. While ensuring reliable air outlet performance, the atomizer using the atomizing component 100 of this application can be designed to be thinner. The ultra-thin design can bring users a novel experience. Due to the ultra-thin design, materials for components can be saved, and smaller packaging can be used, thereby reducing transportation costs.

[0061] In some embodiments, the end of the guide block 411 and the end of the air passage 5 may abut against each other. In some embodiments, the end of the guide block 411 and one end of the air passage 5 may be connected as one unit. With this configuration, during the assembly process, the seal 4 can be assembled to one end of the bracket 1 first, and then the air passage 5 can be assembled into the mounting groove 12. The two can be combined into one workpiece, which can simplify the picking and placing operation during assembly, thereby improving assembly efficiency.

[0062] Furthermore, the outer side of the air passage component 5 is provided with abutting protrusions 52. Specifically, in this embodiment, two vertically extending abutting protrusions 52 are provided on the side of the air passage component 5 away from the oil guide body 2. Both ends of the abutting protrusions 52 are provided with bevels. When the atomizing component 100 is assembled into the oil cup 200, the bevels can guide and facilitate assembly. After assembly, the abutting protrusions 52 abut against the inner wall of the oil cup 200. Under the action of the inner wall of the oil cup 200, the air passage component 5 can fit more tightly against the oil guide body 2 and the heating element 3.

[0063] Furthermore, a first liquid discharge channel 13 is provided at the top of the support 1, and a second liquid discharge channel 14 is formed inside the support 1, which communicates with the first liquid discharge channel 13 and is in contact with the liquid absorption surface. The sealing member 4 includes a main body 41 sleeved on the top of the support 1 and an extension 42 extending from the bottom side of the main body 41 toward the bottom. The extension 42 is attached to one side of the support 1, and a liquid discharge hole 413 communicating with the first liquid discharge channel 13 is provided at the top of the main body 41.

[0064] Specifically, in this embodiment, combined with Figure 3 , Figure 7 , Figure 8 and Figure 9The top of the main body 41 has two symmetrically distributed liquid outlets 413 on both sides of the air guide hole 412. The top of the bracket 1 has a first liquid outlet channel 13 corresponding to the liquid outlets 413. The first liquid outlet channel 13 is set vertically or inclined. The bottom ends of the two first liquid outlet channels 13 are connected to a second liquid outlet channel 14. The second liquid outlet channel 14 is located on the side of the oil guide body 2 away from the atomizing chamber 10. Since the atomizing chamber 10 is offset to one side of the central axis of the atomizing component 100 in this embodiment, the second liquid outlet channel 14 is given room. Therefore, the width of the second liquid outlet channel 14 in the thickness direction of the atomizing component 100 can be set to be larger. In this way, the atomizing liquid can flow more smoothly to the oil guide body 2, improving the space utilization rate in the thickness direction of the atomizing component 100, and making the formed atomizer thinner, reaching 6.5-7.7mm.

[0065] Furthermore, a clearance space is provided on the support 1 at a location away from the oil guide body 2 in the second fluid channel 14, forming at least a portion of the second fluid channel 14. In this embodiment, a second clearance through hole 15 is provided on one side of the support 1, communicating with the first fluid channel 13 and corresponding to the first clearance through hole 421, and the second clearance through hole 15 defines the aforementioned clearance space. In some embodiments, a clearance groove with an opening facing the oil guide body 2 may also be provided in the support 1, and the clearance groove defines the clearance space.

[0066] Furthermore, in this embodiment, the extension 42 is provided with a through first clearance hole 421, and the inner cavities of the first clearance hole 421 and the second clearance hole 15 together form at least a portion of the second liquid channel 14. Specifically, the extension 42 is only provided on one side of the main body 41. Therefore, the bracket 1 is only in contact with the seal 4 on one side. The outer side of the extension 42 is provided with a sealing rib around the first clearance through hole 421. The main body 41 is provided with a sealing rib around its outer side. When the atomizing component 100 is assembled in the oil cup 200, a liquid storage cavity is formed between the sealing component and the oil cup 200. The sealing rib abuts against the inner wall of the oil cup 200, thereby preventing the atomized liquid from leaking out from the gap between the atomizing component 100 and the inner wall of the oil cup 200. The first clearance through hole 421, the second clearance through hole 15 and the inner wall of the oil cup 200 together form part of the second liquid channel 14, which can save materials, effectively utilize the internal space of the atomizing component 100, and make the atomized liquid flow more smoothly to the guide oil body 2. The resulting atomizer can be designed to be thinner, reaching 6.5-7.7mm.

[0067] Furthermore, the atomizing assembly 100 also includes a base 6 connected to the bottom end of the bracket 1 and two electrodes 7 passing through the base 6. The two electrodes 7 extend into the mounting groove 12, and the two ends of the heating element 3 are respectively connected to the same side of the two electrodes 7. The heating element 3 is pressed against the oil-absorbing surface of the oil guide body 2 by the electrodes 7. Specifically, the two electrodes 7 pass through the bottom opening of the mounting groove 12, and the two electrodes 7 are respectively arranged on opposite sides of the mounting groove 12.

[0068] Furthermore, the bracket 1 has a snap-fit ​​groove 16, which has a first opening at the bottom end of the bracket 1 and a second opening on the same side as the mounting groove 12. The atomizing assembly 100 also includes a snap-fit ​​post 8 fixed to the base 6 and extending parallel to the electrode 7. The snap-fit ​​post 8 snaps into the second opening and the snap-fit ​​groove 16. Specifically, the bracket 1 has two snap-fit ​​grooves 16 symmetrically distributed on both sides of the mounting groove 12. Correspondingly, two snap-fit ​​posts 8 are fixed on the base 6. The side wall of the snap-fit ​​groove 16 is provided with a limiting protrusion. The side of the snap-fit ​​post 8 corresponding to the limiting protrusion is provided with a limiting groove. The snap-fit ​​post 8 is embedded in the limiting groove. Therefore, the snap-fit ​​post 8 will not slide relative to the bracket 1 in the vertical direction. Thus, with the cooperation of the snap-fit ​​post 8 and the snap-fit ​​groove 16, the bracket 1 and the base 6 can be fixed stably.

[0069] Further integration Figure 10 and Figure 11 The atomizing assembly 100 also includes a bottom seal 9 connected between the base 6 and the bracket 1. An air inlet chamber 30 is formed between the base 6 and the bottom seal 9. The base 6 has a first air inlet 61 that connects the air inlet chamber 30 to the outside atmosphere, and the bottom seal 9 has a second air inlet 91 that connects the air inlet chamber 30 and the atomizing chamber 10. The first air inlet 61 is coaxial with the central axis of the atomizing assembly 100, and the second air inlet 91 is located on one side of the central axis of the atomizing assembly 100. The first air inlet 61 is located in the middle of the base 6. The first air inlet 61 is a round hole, which can ensure sufficient air intake flow. The second air inlet 91 is a rectangular hole. The air passage 5 and the oil guide 2 form an air intake channel connected to the end of the atomizing chamber 10 away from the air outlet channel 20. The airflow can enter the air intake channel through the first air inlet 61, the air intake chamber 30 and the second air inlet 91. Moreover, before entering the atomizing chamber 10, the cross-sectional area of ​​the air intake channel gradually decreases, which can increase the airflow velocity in the atomizing chamber 10, thereby quickly carrying away the aerosol formed in the atomizing chamber 10 to improve the atomization effect.

[0070] Furthermore, a ventilation groove 17 is provided on the outer side of the bracket 1, with one end connected to the snap-fit ​​groove 16 and the other end connected to the first liquid discharge channel 13. At least one Tesla valve structure 171 is provided in the middle of the ventilation groove 17. Specifically, the top end of the ventilation groove 17 extends upward to the top opening of the first liquid discharge channel 13, and the bottom end of the ventilation groove 17 extends downward to the snap-fit ​​groove 16. The snap-fit ​​groove 16 is connected to the air inlet chamber 30. One, two, three, etc. Tesla valve structures 171 can be provided between the ventilation grooves 17. The direction in which the fluid flow resistance of the Tesla valve is small is set as positive, and the positive direction of each Tesla valve is from bottom to top. After the atomizing component 100 is assembled into the oil cup 200, the ventilation groove 17 and the inner wall of the oil cup 200 together form a ventilation channel. When the fluid flows from the bottom to the top of the ventilation channel, the resistance is smaller, and when the fluid flows from the top to the bottom of the ventilation channel, the resistance is greater. Therefore, the gas can more easily enter the liquid storage chamber through the ventilation channel to maintain the basic balance between the gas pressure in the liquid storage chamber and the external gas pressure. The atomized liquid in the liquid storage chamber is more difficult to flow out from the ventilation channel, thereby preventing leakage from the ventilation channel.

[0071] Based on the composition of the various components of the atomizing component 100 described in this embodiment, the atomizing component 100 of this solution can make full use of its own space, thereby achieving reliable performance in terms of air intake, air output, air exchange, e-liquid flow, and sealing. This allows the assembled atomizer to achieve an ultra-thin thickness of 6.5-7.7mm. In addition, the composition of the components in this solution makes the atomizer assembly process simple and quick, which can improve the production efficiency of the atomizer and reduce the production cost. The assembly process of the atomizer of this application is briefly described below:

[0072] Combination Figure 10 and Figure 11 The electrode 7 and the snap-fit ​​post 8 are then inserted and assembled from the bottom of the base 6. At this point, the positions of the electrode 7 and the snap-fit ​​post 8 relative to the base 6 are fixed. Then, the bottom silicone is fitted onto the base 6, and the electrode 7 and the snap-fit ​​post 8 pass through the bottom silicone. Sealing ribs are also provided on the outside of the bottom silicone. After that, the heating element 3 is pre-welded to the same side of the two electrodes 7.

[0073] Combination Figure 5 The oil guide 2 is assembled into the mounting groove 12 of the bracket 1. It should be understood that this installation process can be carried out simultaneously with the aforementioned installation process to save assembly time.

[0074] Combination Figure 4 and Figure 5The snap-fit ​​post 8 and the electrode 7 with the heating element 3 welded on are pressed together from one side of the bracket 1, so that the snap-fit ​​post 8 and the snap-fit ​​groove 16 are snapped and fixed. The electrode 7 is embedded in the mounting groove 12, and the heating element 3 is pressed against the atomizing surface of the oil guide body 2. Then the air passage 5 is embedded in the mounting groove 12, and the sealing element 4 and the top of the bracket 1 are assembled. At this time, the main body 41 is connected to the top of the bracket 1, and the extension 42 is attached to one side of the bracket 1, thereby forming the atomizing assembly 100.

[0075] Combination Figure 1 Finally, the atomizing component 100 is assembled into the oil cup 200 from one end, and the iron cover 300 is pressed and fixed to the end of the oil cup 200 to complete the assembly of the entire atomizer.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
