Description

Technical Field

[0001] This invention belongs to the field of electronic atomization technology, and particularly relates to an atomizer and an electronic atomization device. 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 solutions in these technologies are adopted, the cross-sectional size of the airflow channel will be drastically reduced to ensure the structural strength and sealing performance of the atomizing component, affecting smoothness. Aerosols are also prone to condensation at the airflow channel, impacting user experience and hindering the development of thinner atomizers. Summary of the Invention

[0005] The technical objective of this invention is to provide an atomizer and an electronic atomizing device that can make the atomizer thinner while ensuring the smoothness of the air outlet channel.

[0006] To solve the above-mentioned technical problems, the present invention provides an atomizer, including an oil cup and an atomizing component. The atomizing component is installed at the bottom of the oil cup and forms a liquid storage cavity with the oil cup. The atomizing component includes a support and a flat oil guide body and a sheet-shaped heating element that are vertically or inclinedly arranged inside the support. The oil guide body has a liquid absorption surface and an atomizing surface, and the heating element is disposed on the atomizing surface of the oil guide body.

[0007] An air outlet channel is formed inside the oil cup. The atomizing component has an atomizing chamber located on one side of the atomizing surface and a connecting channel connecting the atomizing chamber and the air outlet channel. The wall of the connecting channel is recessed in a direction away from the central axis of the atomizer to form a clearance cavity.

[0008] Furthermore, the clearance cavity has a first guide surface connected to the atomizing chamber at one end and a second guide surface connected to the air outlet channel at the other end, and the other ends of the first guide surface and the second guide surface both extend in a direction away from the central axis of the atomizer.

[0009] Furthermore, the clearance cavity also has a third guide surface connected to the other end of the first guide surface and the other end of the second guide surface, the third guide surface being the inner wall surface of the oil cup.

[0010] Furthermore, the cross-sectional area of ​​the portion of the connecting channel corresponding to the first guide surface gradually increases from the atomizing chamber toward the air outlet channel.

[0011] Furthermore, the angle between the first guide surface and the central axis of the atomizer is 15-60°.

[0012] Furthermore, the angle between the second guide surface and the central axis of the atomizer is 30-75°.

[0013] Furthermore, the first guiding surface is a plane;

[0014] Alternatively, the first guide surface may be curved, and the side of the first guide surface facing the central axis of the atomizer may be convex or concave.

[0015] Furthermore, the second guide surface is a plane;

[0016] Alternatively, the second guide surface may be curved, and the side of the second guide surface facing the central axis of the atomizer may be convex or concave.

[0017] Furthermore, the atomizing chamber is offset to one side of the central axis of the atomizer, and the atomizing assembly also forms an oil-down channel that communicates with the liquid storage chamber and is in contact with the liquid-absorbing surface of the oil guide body, with at least a portion of the oil-down channel located on the other side of the central axis.

[0018] Furthermore, the atomizing component also includes a sealing member sleeved on the top of the bracket, the top of the sealing member having a through air guide hole for connecting the air outlet channel, and a flow guide block provided on the bottom side of the sealing member, the second flow guide surface being disposed on the flow guide block.

[0019] Furthermore, a mounting groove is provided on one side of the bracket, the oil guide body is disposed in the mounting groove, and the atomizing assembly also includes an air passage component assembled in the mounting groove. The oil guide body and the air passage component together enclose the atomizing chamber, and the first flow guide surface is disposed on the air passage component.

[0020] Furthermore, the top of the bracket is provided with an air outlet notch that connects to the mounting groove. The air outlet notch connects to the air guide hole. The guide block is embedded in the notch of the air outlet notch, and the second guide surface faces into the air outlet notch.

[0021] Furthermore, both the guide block and the air passage component are tightly attached to the inner wall of the oil cup, and a clearance opening is formed between the guide block and the air passage component. The third guide surface is formed by the inner wall of the oil cup that is sealed in the clearance opening.

[0022] Furthermore, the air outlet has a fourth guide surface located on the opposite side of the second guide surface, one end of the fourth guide surface is connected to the air guide hole, and the other end of the fourth guide surface extends toward the first guide surface.

[0023] Furthermore, the angle between the fourth guide surface and the second guide surface is 0-20°.

[0024] Furthermore, the atomizing assembly also includes a base connected to the bottom end of the oil cup and a bottom seal connecting the base and the bracket. An air intake chamber is formed between the base and the bottom seal. The base has a first air intake hole that connects the air intake chamber to the outside atmosphere, and the bottom seal has a second air intake hole that connects the air intake chamber and the atomizing chamber.

[0025] Furthermore, the air passage component and the oil guide body together form an air intake channel connected to the end of the atomizing chamber away from the connecting channel. The wall of the air intake channel is recessed in the direction away from the oil guide body. The first air intake hole is coaxial with the central axis of the atomizer, and the second air intake hole is located on one side of the central axis of the atomizer.

[0026] Furthermore, the cross-sectional area of ​​the air intake channel gradually increases within a predetermined length range from the atomizing chamber toward the bottom.

[0027] Furthermore, the thickness of the atomizer ranges from 6.5 to 7.7 mm.

[0028] Furthermore, an electronic atomizing device is provided, comprising the atomizer as described in any of the above claims.

[0029] Compared with the prior art, the atomizer and electronic atomization device of this invention have the following advantages:

[0030] In this design, the atomizing liquid is heated and atomized within the atomization chamber by a heating element after passing through the oil guide. Outside air enters the atomization chamber and mixes with the atomized liquid to form an aerosol. This aerosol is then expelled to the outside environment through the connecting channel and the outlet channel for the user to inhale. Because the wall of the connecting channel is recessed away from the atomizer's central axis, creating a clearance cavity, the cross-section of the connecting channel is increased, allowing for smoother aerosol flow and minimizing condensation during the outlet process. Furthermore, the clearance cavity reduces the amount of material forming the connecting channel in the atomization assembly, allowing for a thinner overall atomizer while ensuring smooth outlet flow.

Detailed Implementation

[0038] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0039] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "circumferential," and "radial," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0040] 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.

[0041] In related technologies, atomizer thickness is generally above 9mm, with a very few ceramic heating element atomizers reaching a thickness of 7.8mm. This size is currently the industry limit, and no thinner atomizers have been found on the market. This is limited by the structure that forms the airway in related technologies. To ensure smooth airflow and reduce condensation, the cross-sectional dimensions or minimum width of the airway need to meet certain standards; otherwise, it is difficult to produce a qualified product. Under the premise of meeting this standard, the current minimum thickness limit for atomizers can only reach 7.8mm.

[0042] In view of the aforementioned situation, this embodiment provides an atomizing device (not shown), including an atomizer, wherein, combined with Figure 1-4 The atomizer includes an oil cup 1 and an atomizing component 2. The atomizing component 2 is installed at the bottom of the oil cup 1 and forms a liquid storage chamber with the oil cup 1. The atomizing component 2 includes a support 21 and a flat oil guide body 22 and a sheet heating element 23 that are vertically or inclinedly arranged inside the support 21. The oil guide body 22 can be made of ceramic or oil guide cotton, etc., and the heating element 23 can be formed by etching a metal sheet. The oil guide body 22 has a liquid absorption surface and an atomizing surface, and the heating element 23 is disposed on the atomizing surface of the oil guide body 22. An air outlet channel 11 is formed in the oil cup 1. The atomizing component 2 has an atomizing chamber 10 located on one side of the atomizing surface and a connecting channel 20 connecting the atomizing chamber 10 and the air outlet channel 11. The wall of the connecting channel 20 is recessed in the direction away from the central axis of the atomizer to form a clearance cavity 30.

[0043] In this design, the atomizing liquid is heated and atomized in the atomization chamber 10 by the heating element 23 after passing through the oil guide 22. Outside air enters the atomization chamber 10 and mixes with the atomized liquid to form an aerosol. The aerosol is then discharged to the outside through the connecting channel 20 and the air outlet channel 11 for the user to inhale. Since the wall of the connecting channel 20 is recessed away from the central axis of the atomizer to form a clearance cavity 30, the clearance cavity 30 can increase the cross-section of the connecting channel 20, making the flow of aerosol smoother. This minimizes the accumulation of condensate formed during the air outlet process and prevents blockage of the channel. Moreover, the clearance cavity 30 can reduce the material in the atomization component 2 that forms the connecting channel 20, allowing the overall thickness of the atomizer to be thinner while ensuring smooth air outlet.

[0044] Furthermore, the clearance cavity 30 has a first guide surface 251 connected at one end to the atomizing chamber 10 and a second guide surface 2421 connected at one end to the air outlet channel 11. The other ends of both the first guide surface 251 and the second guide surface 2421 extend away from the central axis of the atomizer. The aerosol formed in the atomizing chamber 10 can be guided by the first guide surface 251, then by the second guide surface 2421, and finally enter the air outlet channel 11. Since the other ends of both the first guide surface 251 and the second guide surface 2421 extend away from the central axis of the atomizer, the cross-section of the aerosol gradually increases during the initial process of passing through the connecting channel 20. After being guided by the second guide surface 2421, the flow is smoother. Therefore, the aerosol is less likely to form condensate during the air outlet process, which can improve the user experience.

[0045] Furthermore, the clearance cavity 30 also has a third guide surface 12 connecting the other end of the first guide surface 251 and the other end of the second guide surface 2421. The third guide surface 12 is the inner wall surface of the oil cup 1. Since the third guide surface 12 connects the first guide surface 251 and the second guide surface 2421, and the third guide surface 12 is the inner wall surface of the oil cup 1, that is, a part of the inner wall surface of the oil cup 1 serves as the wall surface of the connecting channel 20, there is no other obstructing material at the third guide surface 12, which can save material costs. Moreover, by reducing the corresponding material at this location, the clearance cavity 30 can be formed to increase the cross-sectional area of ​​the connecting channel 20, improve the smoothness of aerosol gas output, and reduce condensation. Under this structural basis, while ensuring the smoothness of aerosol gas output, the overall thickness of the atomizer can be reduced, so that the thickness range of the atomizer can be 6.5-7.7mm, breaking through the minimum thickness limit of atomizers in the prior art.

[0046] Furthermore, the cross-sectional area of ​​the portion of the connecting channel 20 corresponding to the first guide surface 251 gradually increases from the atomizing chamber 10 toward the outlet channel 11. Preferably, the angle between the first guide surface 251 and the central axis of the atomizer is 15-60°. Specifically, in this embodiment, the first guide surface 251 is a plane, and the angle between the first guide surface 251 and the central axis of the atomizer is 30°. In some embodiments, the first guide surface 251 may also be a curved surface, with the side of the first guide surface 251 facing the central axis of the atomizer being convex or concave. It should be understood that the angle between the tangent at any point of the first guide surface 251 and the central axis of the atomizer is between 15-60°. Through the aforementioned arrangement, the cross-section of the connecting channel 20 gradually increases from its end connected to the atomizing chamber 10, and the rate of increase is stable, which makes the outlet airflow smoother and less prone to condensation. It should be understood that the first guide surface 251 can be in other forms besides the aforementioned configuration, such as multiple planes, multiple curved surfaces, or a combination of planes and curved surfaces. As long as the cross-sectional area of ​​the part of the connecting channel 20 corresponding to the first guide surface 251 gradually increases from the atomizing chamber 10 toward the air outlet channel 11, it is within the scope of protection of this application.

[0047] Furthermore, the angle between the second guide surface 2421 and the central axis of the atomizer is 30-75°. Specifically, in this embodiment, the second guide surface 2421 is a plane, and the angle between the second guide surface 2421 and the central axis of the atomizer is 45°. In some embodiments, the second guide surface 2421 may also be a curved surface, with the side of the second guide surface 2421 facing the central axis of the atomizer being convex or concave. It should be understood that the angle between the tangent at any point of the second guide surface 2421 and the central axis of the atomizer is between 30-75°. Through the aforementioned arrangement, the airflow can be guided, allowing the aerosol to flow towards the air outlet channel 11, and the airflow can be made smoother and less prone to condensation. It should be understood that the second guide surface 2421 can also be other arrangements besides the aforementioned arrangement, such as multiple plane segments, multiple curved surfaces, or a combination of planes and curved surfaces.

[0048] Furthermore, the atomizing chamber 10 is offset to one side of the central axis of the atomizer. The atomizing assembly 2 also forms a lower oil channel that communicates with the liquid storage chamber and is connected to the liquid absorption surface of the oil guide 22. At least a portion of the lower oil channel is located on the other side of the central axis. Specifically, in this embodiment, the atomizing surface of the oil guide 22 is located on the central axis of the atomizer, that is, one side wall of the atomizing chamber 10 is exactly on the central axis of the atomizer; the sealing member 24 includes an extension with a through clearance hole. The extension is clamped and fixed between the bracket 21 and the inner wall of the oil cup 1. The bracket 21, the clearance hole, and the inner wall of the oil cup 1 together form part of the lower oil channel, and the portion of the lower oil channel corresponding to the clearance hole is located on one side of the liquid absorption surface of the oil guide 22, that is, on the side of the oil guide 22 away from the atomizing chamber 10. Since the atomizing chamber 10 is offset to the central axis of the atomizer... On one side, the lower oil channel can be repositioned, allowing for a larger cross-sectional area within the limited space of the atomizer. Furthermore, since part of the lower oil channel is formed by the repositioning hole of the extension, the cross-sectional area of ​​the lower oil channel can be further increased while saving material. This design can increase the width of the lower oil channel in the thickness direction within the limited thickness of the atomizer. In other words, while ensuring normal atomization of the atomization chamber 10 and smooth oil flow in the lower oil channel, this technical solution can make the overall thickness of the atomizer thinner, reaching 6.5-7.7mm.

[0049] It should be understood that in some embodiments, the atomizing chamber 10 may be entirely located on one side of the atomizer's central axis, meaning that the sidewalls of the atomizing chamber 10 are all on one side of the atomizer's central axis. Of course, in some embodiments, the atomizing chamber 10 may be mostly located on one side of the atomizer's central axis, with a small portion located on the other side. Preferably, more than 80% of the atomizing chamber 10 may be located on one side of the atomizer's central axis, with the remainder on the other side. It should be understood that when using the atomizer's central axis as the boundary for the allocation of the atomizing chamber 10, the plane passing through the atomizer's central axis and parallel to the atomizing surface of the oil guide 22 is taken as the interface.

[0050] In this embodiment, the atomizing assembly 2 includes a seal 24, a bracket 21, an oil guide 22, a heating element 23, a base 26, and an iron cover 28. The seal 24 can be made of silicone or rubber and is fitted onto the top of the bracket 21 and sealed to the inner wall of the oil cup 1. The base 26 is fixed to the bottom of the bracket 21 and fixedly connected to the inner wall of the oil cup 1. The oil guide 22 is preferably vertically arranged inside the bracket 21, with its atomizing surface facing the atomizing chamber 10. The heating element 23 is attached to the atomizing surface of the oil guide 22 and electrically connected to two electrodes passing through the base 26. The iron cover 28 is disposed at the bottom of the base 26 and fixed to the oil cup 1. In practical applications, the oil guide 22 can also be inclined, that is, the angle between the oil guide 22 and the bottom surface of the atomizing assembly 2 can be in the range of 60° to 120°.

[0051] Furthermore, a through-hole 241 is provided at the top of the sealing element 24, which is used to connect to the air outlet channel 11. A guide block 242 is provided on the bottom side of the sealing element 24, and a second guide surface 2421 is provided on the guide block 242. A mounting groove 211 is provided on one side of the bracket 21, and the oil guide body 22 is provided in the mounting groove 211. The atomizing assembly 2 also includes an air passage component 25 assembled in the mounting groove 211. The oil guide body 22 and the air passage component 25 together form an atomizing chamber 10, and a first guide surface 251 is provided on the air passage component 25. The air passage component 25 is preferably made of an elastic material such as silicone, so as to form a good sealing and fixing effect with the inner wall of the mounting groove 211.

[0052] Specifically, the oil cup 1 has an air guide tube, one end of which is inserted into the air guide hole 241. The top of the bracket 21 has an air outlet notch 212 that connects to the mounting groove 211. The air guide hole 241 and the air outlet notch 212 are positioned opposite each other and connected. The guide block 242 is embedded in the notch of the air outlet notch 212, and the second guide surface 2421 faces the air outlet notch 212. Through the cooperation of the second guide surface 2421 and the air outlet notch 212, a through hole is formed connecting the channel 20 to the air outlet channel 11. This design saves material on the bracket 21 without affecting the aerosol output. Moreover, since the atomizing chamber 10 is offset from one side of the atomizer's central axis, the guide effect of the second guide surface 2421 can guide the originally offset aerosol into the air outlet channel 11, which not only ensures the smoothness of the airflow but also reduces the atomizer's thickness, making it easier to make the atomizer thinner overall.

[0053] Furthermore, in this solution, the air outlet notch 212 is U-shaped. In some embodiments, the air outlet notch 212 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 242 can be adapted to the shape of the air outlet notch 212, as long as it can match the notch of the air outlet notch 212 and form a through hole with the air outlet notch 212.

[0054] Furthermore, the air outlet 212 has a fourth guide surface 2121 located opposite the second guide surface 2421. One end of the fourth guide surface 2121 is connected to the air inlet 241, and the other end of the fourth guide surface 2121 extends toward the first guide surface 251. Preferably, the angle between the fourth guide surface 2121 and the second guide surface 2421 is 0-20°. The extension directions of the second guide surface 2421 and the fourth guide surface 2121 are approximately the same, that is, the cross-section of the channel formed between the second guide surface 2421 and the fourth guide surface 2121 is approximately the same. Both the second guide surface 2421 and the fourth guide surface 2121 are connected to one end of the air outlet channel 11, which allows the cross-section at the junction of the connecting channel 20 and the air outlet channel 11 to be larger, ensuring that the aerosol flows smoothly to the air outlet channel 11, making the atomizer more reliable.

[0055] Furthermore, both the guide block 242 and the air passage component 25 are tightly attached to the inner wall of the oil cup 1, forming a clearance opening between them. The third guide surface 12 is formed by the inner wall of the oil cup 1 that seals the clearance opening. It is understandable that when the seal 24 and the air passage component 25 are both assembled on the bracket 21, a connecting channel 20 can be formed. However, a clearance opening connecting the guide block 242 and the air passage component 25 is formed, but this clearance opening is sealed by the inner wall of the oil cup 1. That is, the inner wall of the oil cup 1 serves as part of the inner wall of the connecting channel 20. Compared to the related technology where the air passage is completely housed within the atomizing assembly 2, this solution saves materials and effectively utilizes the fit between the components to form a clearance cavity 30. This increases the cross-sectional area of ​​the connecting channel within the limited space of the atomizer, thereby reducing aerosol condensation and allowing the atomizer to be made thinner while maintaining reliability. The ultra-thin design offers users a novel experience. Because of its thinness, it saves on component materials and allows for smaller packaging, thus reducing transportation costs.

[0056] Further integration Figure 5 and Figure 6The atomizing assembly 2 also includes a base 26 connected to the bottom end of the oil cup 1 and a bottom seal 27 connected between the base 26 and the bracket 21. An air inlet chamber 40 is formed between the base 26 and the bottom seal 27. The base 26 has a first air inlet hole 261 that connects the air inlet chamber 40 to the outside atmosphere, and the bottom seal 27 has a second air inlet hole 271 that connects the air inlet chamber 40 and the atomizing chamber 10. Specifically, the air passage 25 and the oil guide 22 enclose and form an air intake channel 50 connected to the end of the atomizing chamber 10 away from the connecting channel 20. The wall of the air intake channel 50 is recessed in the direction away from the oil guide 22. The first air intake hole 261 is coaxial with the central axis of the atomizer. The iron cover 28 is provided with a through hole corresponding to the first air intake hole 261. The second air intake hole 271 is located on one side of the central axis of the atomizer, which is equivalent to the second air intake hole 271 being eccentrically set. The cross-sectional area of ​​the air intake channel 50 gradually increases within a predetermined length range from the atomizing chamber 10 toward the bottom. The first air inlet 261 is located in the middle of the base 26. The first air inlet 261 is a round hole, which can ensure sufficient air intake flow. The second air inlet 271 is a rectangular hole. The airflow can enter the air intake channel 50 through the first air inlet 261, the air intake chamber 40 and the second air inlet 271. Moreover, before entering the atomizing chamber 10, the cross-sectional area of ​​the air intake channel 50 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.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. 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.
