Description

Technical Field

[0001] This invention belongs to the field of electronic atomization technology, and particularly relates to an atomizer and 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. An oil inlet channel is formed within the atomizing component, usually vertically positioned at the top or side of the component. However, with the atomizer becoming thinner, employing the aforementioned technologies drastically reduces the cross-sectional size of the oil inlet channel to maintain the structural strength and sealing performance of the atomizing component. This results in poor oil flow, hindering the development of thinner atomizers. Summary of the Invention

[0005] The technical objective of this invention is to provide an atomizer and atomizing device that can make the overall thickness of the atomizer thinner while ensuring oil intake performance.

[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 attached to the atomizing surface of the oil guide body.

[0007] The upper end of the bracket is provided with a first oil inlet channel that connects to the liquid storage chamber. The bracket is also provided with a second oil inlet channel that connects the first oil inlet channel and the oil guide body. The second oil inlet channel is located on the liquid absorption side of the oil guide body.

[0008] Furthermore, the upper end of the bracket is provided with two first oil inlet channels, and the second oil inlet channel is connected to the two first oil inlet channels.

[0009] Furthermore, the angle between the extending direction of the second oil inlet channel and the extending direction of the first oil inlet channel is 90° to 135°.

[0010] Furthermore, a clearance cavity is formed on the side of the second oil inlet channel opposite to the atomizing surface.

[0011] Furthermore, the clearance cavity is a groove with its opening facing the second oil inlet channel.

[0012] Furthermore, the clearance cavity is an opening that penetrates the outer side of the support.

[0013] Furthermore, the atomizing assembly also includes a seal fitted onto the upper end of the bracket, the seal having an extension extending from the upper end of the bracket along one side of the bracket toward the bottom, and at least a portion of the second oil inlet channel is formed between the bracket and the extension.

[0014] Furthermore, the extension is provided with an oil passage hole corresponding to the position of the relief cavity, and the relief cavity, the oil passage hole and the inner wall of the oil cup together form at least a part of the second oil inlet channel.

[0015] Furthermore, the end of the second oil inlet channel bends and extends toward the upper end of the seal.

[0016] Furthermore, the seal also has a main body portion sleeved on the upper end of the bracket, and the upper end of the main body portion has a lower oil hole with a position corresponding to the first oil inlet channel.

[0017] Furthermore, a first sealing rib is provided around the periphery of the main body, and the first sealing rib abuts against the inner wall of the oil cup;

[0018] The extension portion is provided with a second sealing rib on the side away from the bracket, which surrounds the outer periphery of the oil passage hole and abuts against the inner wall of the oil cup.

[0019] Furthermore, the extension is connected to the bottom end of one side of the main body, and a positioning groove is provided on one side of the bracket, with the extension embedded in the positioning groove.

[0020] Furthermore, the outer surface of the extension is flush with the opening of the positioning groove.

[0021] Furthermore, the atomizer has a thickness dimension of 6.5-7.7 mm.

[0022] Furthermore, the liquid absorption surface is parallel to the width direction of the atomizer, and the length extension direction of the second oil inlet channel is parallel to the liquid absorption surface.

[0023] Furthermore, an atomizing chamber corresponding to the heating element is formed inside the bracket, and the atomizing chamber is located on the other side of the central axis of the atomizer relative to the second oil inlet channel.

[0024] Furthermore, an atomizing device is provided, comprising an atomizer as described in any of the preceding claims.

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.

[0035] 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 due to the limitations imposed by the structure that forms the oil inlet channel in related technologies. To ensure the smooth flow of oil through the oil inlet channel, the cross-sectional dimensions or minimum width of the oil inlet channel need to meet certain standards; otherwise, it is difficult to produce a qualified product. Under the premise of meeting this standard, the current minimum limit for atomizer thickness is only 7.8mm.

[0036] To address this 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 bracket 21 and an oil guide body 23 and a heating element that are vertically or inclinedly arranged inside the bracket 21. The oil guide body 23 is flat and has a liquid absorption surface and an atomizing surface. The heating element is sheet-shaped and is attached to the atomizing surface of the oil guide body 23. The upper end of the bracket 21 is provided with a first oil inlet channel 211 that connects to the liquid storage chamber. The bracket 21 is also provided with a second oil inlet channel 20 that connects the first oil inlet channel 211 and the oil guide body 23. That is, the second oil inlet channel 20 is located on the liquid absorption surface side of the oil guide body 23.

[0037] In this design, at least a portion of the second oil inlet channel 20 is located between the liquid absorption surface of the oil guide body 23 and the inner wall of the support 21. The atomized liquid in the storage chamber enters the first oil inlet channel 211 from the upper end of the support 21, flows through the second oil inlet channel 20 located on one side of the oil guide body 23, enters the oil guide body 23, and is heated and atomized by the heating element to form an aerosol. By setting the second oil inlet channel 20, the flow direction of the atomized liquid in the first oil inlet channel 211 changes. The vertically or inclined flat plate oil guide body 23 provides sufficient liquid absorption area on its side. Compared with top-down oil supply, it can make the overall thickness of the atomizer thinner while ensuring smooth oil supply.

[0038] Furthermore, the upper end of the bracket 21 is provided with two first oil inlet channels 211, and the second oil inlet channel 20 connects the two first oil inlet channels 211.

[0039] The two ends of the second oil inlet channel 20 are respectively connected to the bottom ends of the two first oil inlet channels 211; the angle between the extension direction of the second oil inlet channel 20 and the extension direction of the first oil inlet channel 211 is 90° to 135°. Preferably, in this embodiment, the angle between the axial direction of the second oil inlet channel 20 and the axial direction of the first oil inlet channel 211 is 90°. Specifically, the first oil inlet channel 211 is vertically arranged, that is, the axial direction of the first oil inlet channel 211 is parallel to the central axis of the atomizer, and the second oil inlet channel 20 is horizontally arranged, that is, the axial direction of the second oil inlet channel 20 is perpendicular to the central axis of the atomizer and perpendicular to the thickness direction of the atomizer. This arrangement can make the cross-section of the second oil inlet channel 20 basically consistent, and ensure that the width of the second oil inlet channel 20 in the thickness direction of the atomizer is as large as possible when the thickness of the atomizer is fixed, thereby improving the oil guiding effect and ensuring the oil guiding performance of the atomizer.

[0040] In some embodiments, the angle between the axial direction of the second oil inlet channel 20 and the axial direction of the first oil inlet channel 211 can be 100°, 110°, 120°, 130°, etc. When the first oil inlet channel 211 is vertically arranged, an obtuse angle is formed between the second oil inlet channel 20 and the first oil inlet channel 211. That is, the second oil inlet channel 20 is inclined downward along the direction away from the first oil inlet channel 211. When the atomizing liquid flows through the second oil inlet channel 20, the atomizing liquid is more likely to flow to the oil guide body 23, thereby achieving a better oil guiding effect.

[0041] In some embodiments, the first oil inlet channel 211 can also be inclined. In this case, the second oil inlet channel 20 can be horizontally arranged, or it can be inclined downwards in a direction away from the first oil inlet channel 211. This arrangement can also make it easier for the atomizing liquid to flow to the oil guide body 23, thereby achieving a better oil guiding effect.

[0042] Furthermore, a clearance cavity 212 is formed on the side of the second oil inlet channel 20 opposite to the atomizing surface. In this embodiment, the clearance cavity 212 is an opening penetrating the outer side of the bracket 21, with the center of the opening directly opposite the center of the oil guide body 23. The opening connects to the bottom end of the first oil inlet channel 211. When the bracket 21 is assembled into the oil cup 1, the clearance cavity 212 can form at least a part of the second oil inlet channel 20 with the inner wall of the oil cup 1. It should be understood that the outer port of the clearance cavity 212 can be directly sealed by the inner wall of the oil cup 1, or a sealing structure can be provided between the outer side of the bracket 21 and the inner wall of the oil cup 1. In some embodiments, the clearance cavity 212 can also be a groove with its opening facing into the second oil inlet channel 20. In this way, the second oil inlet channel 20 can be completely located inside the bracket 21, and there is no need to consider the oil leakage problem of the second oil inlet channel 20 when assembling the bracket 21 and the oil cup 1, making the installation more convenient and quick.

[0043] It should be understood that by providing a clearance cavity 212 on the bracket 21 to form at least a portion of the second oil inlet channel 20, the material of the bracket 21 can be saved, thereby increasing the cross-sectional area of ​​the second oil inlet channel 20, which is more conducive to making the atomizer thinner.

[0044] Furthermore, the atomizing assembly 2 also includes a seal 22 sleeved on the upper end of the bracket 21. The seal 22 has an extension 222 extending from the upper end of the bracket 21 along one side of the bracket 21 toward the bottom. At least a portion of the second oil inlet channel 20 is formed between the bracket 21 and the extension 222.

[0045] Furthermore, the sealing element 22 also has a main body 221 sleeved on the upper end of the bracket 21, and the upper end of the main body 221 has a lower oil hole 2211 corresponding to the position of the first oil inlet channel 211. Specifically, in this embodiment, the upper end of the bracket 21 is symmetrically provided with two first oil inlet channels 211 about the atomizer central axis. Correspondingly, the upper end of the main body 221 has two lower oil holes 2211. The atomized liquid in the liquid storage chamber can enter the corresponding first oil inlet channel 211 through the lower oil hole 2211, and then enter the second oil inlet channel 20 to achieve reliable oil guiding.

[0046] In some embodiments, to further increase the width of the first oil inlet channel 211 in the thickness direction, the bracket 21 may have a notch on the thickness direction side of the atomizer, and a rigid support ring may be integrally injection molded inside the main body 221. The support ring is arranged around the outside of all the lower oil holes 2211. The support ring may be made of a hard material such as ceramic or metal. In this way, when the main body 221 is fitted onto the upper end of the bracket 21, the support ring is located on the outside of the bracket 21. Under the combined action of the support ring and the bracket 21, the structural strength of the main body 221 can be guaranteed, so that the main body 221 can tightly abut against the inside of the oil cup 1, ensuring the sealing between the oil cup 1 and the seal 22. That is, in this implementation, the material of the bracket 21 surrounding the first oil inlet channel 211 in the thickness direction is reduced, thereby increasing the width of the first oil inlet channel 211 in the thickness direction, enhancing the oil guiding effect of the first oil inlet channel 211, and reducing the oil guiding pressure of the second oil inlet channel 20, so as to better break through the minimum setting limit of the atomizer thickness.

[0047] Furthermore, the extension 222 is provided with an oil passage hole 2221 corresponding to the position of the clearance cavity 212. The clearance cavity 212, the oil passage hole 2221, and the inner wall of the oil cup 1 together form at least a part of the second oil inlet channel 20. Preferably, the clearance cavity 212 extends along the width direction of the atomizer, and both ends of the clearance cavity 212 are respectively connected to the two first oil inlet channels 211. The centers of the clearance cavity 212 and the oil passage hole 2221 are both aligned with the center of the oil guide body 23. Therefore, since both ends of the second oil inlet channel 20 are respectively connected to the two first oil inlet channels 211, the atomized liquid is simultaneously conducted from both ends of the second oil inlet channel 20 to the middle, which can ensure the smooth flow of oil. In this application, the groove wall of the clearance cavity 212 and the hole wall of the oil passage 2221 are both used as the sidewalls of the second oil inlet channel 20, which is equivalent to saving the material of the bracket 21 and the seal 22 in the thickness direction of the atomizer, thereby widening the second oil inlet channel 20. When the thickness of the atomizer is fixed, the width of the second oil inlet channel 20 in the thickness direction of the atomizer can be larger.

[0048] In some embodiments, the clearance cavity 212 can also be configured as a V-shape, that is, both ends of the clearance cavity 212 are inclined, so that the atomized liquid at both ends of the second oil inlet channel 20 can more easily enter the middle, further improving the oil guiding effect. It should be understood that the configuration of the oil through hole 2221 can be adaptively adjusted to a V-shape according to the configuration of the clearance cavity 212.

[0049] Furthermore, the end of the second oil inlet channel 20 bends and extends towards the upper end of the seal 22. That is, both ends of the clearance cavity 212 can be bent and extended upwards, and adaptably, both ends of the oil passage 2221 can also be bent and extended upwards. With this configuration, the second oil inlet channel 20 can be U-shaped, smile-shaped, ︺-shaped, etc., thereby further improving the smoothness of oil inlet. In some embodiments, the second oil inlet channel 20 can be bent and extended towards the upper end of the seal 22 at only one end.

[0050] Furthermore, the groove wall of the first oil inlet channel 211 and / or the groove wall of the relief cavity 212 are provided with an expansion groove and / or an expansion hole communicating with the relief cavity 212. By providing an expansion groove or an expansion hole on the groove wall of the first oil inlet channel 211, or on the groove wall of the relief cavity 212, the cross-sectional area of ​​the first oil inlet channel 211 or the second oil inlet channel 20 can be increased, thereby improving the smoothness of oil inlet. It should be understood that when the side wall of the bracket 21 is provided with the aforementioned through expansion hole, the outer end of the expansion hole is covered by the inner side of the extension 222, thereby ensuring sealing.

[0051] Furthermore, a first sealing rib 2212 is arranged around the periphery of the main body 221, and the first sealing rib 2212 abuts against the inner wall of the oil cup 1; a second sealing rib 2222 is arranged around the outer periphery of the oil passage 2221 on the side of the extension 222 away from the bracket 21, and the second sealing rib 2222 abuts against the inner wall of the oil cup 1. The first sealing rib 2212 prevents the atomized liquid in the liquid storage chamber from flowing out from the gap between the seal 22 and the inner wall of the oil cup 1, and the second sealing rib 2222 prevents the atomized liquid in the second oil inlet channel 20 from flowing out from the gap between the seal 22 and the inner wall of the oil cup 1. With the cooperation of the two, good sealing performance can be ensured, thereby ensuring the reliability of the atomizer.

[0052] Furthermore, the extension 222 is connected to the bottom end of one side of the main body 221, and a positioning groove 213 is provided on one side of the bracket 21, with the extension 222 embedded in the positioning groove 213. Specifically, in this embodiment, the main body 221 has an extension 222 on only one side, and by providing a positioning groove 213 for embedding the extension 222 on one side of the bracket 21, on the one hand, the material of the seal 22 in the atomizer thickness direction can be reduced, thereby reducing the ultimate thickness of the atomizer; on the other hand, during the assembly of the seal 22 and the bracket 21, since the seal 22 has an asymmetrical structure, it can prevent mistake-proofing and ensure the assembly accuracy of the seal 22 and the bracket 21. The outer surface of the extension 222 can be flush with the opening of the positioning groove 213. Similarly, the outer surface of the main body 221 can also be flush with the opening of the positioning groove 213. Therefore, after the seal 22 and the bracket 21 are assembled, their outer surfaces are smoother, the overall integrity is better, and assembly is easier.

[0053] Furthermore, the atomizer's thickness is between 6.5 and 7.7 mm. The oil channel design in this solution allows for an ultra-thin atomizer, providing users with a novel experience. This ultra-thin design also saves on component materials and allows for smaller packaging, thus reducing transportation costs.

[0054] Furthermore, the liquid-absorbing surface of the oil guide 23 is parallel to the width direction of the atomizer, and the length extension direction of the second oil inlet channel 20 is parallel to the liquid-absorbing surface. Specifically, in this embodiment, the bottom surfaces of the oil guide 23 and the atomizing component 2 are set at 90°, that is, the liquid-absorbing surface is perpendicular to the bottom surface of the atomizing component 2 and perpendicular to the thickness direction of the atomizer, and the second oil inlet channel 20 is set horizontally. In this application, the ratio between the minimum width of the second oil inlet channel 20 in the thickness direction of the atomizer and the dimension of the atomizer in the thickness direction is within 0.15-0.35, and the minimum width of the second oil inlet channel 20 in the thickness direction of the atomizer is greater than 1.6mm. With the structure of this solution, when the atomizer thickness is less than 7.7mm, the ratio between the minimum width of the second oil inlet channel 20 in the thickness direction of the atomizer and the dimension of the atomizer in the thickness direction can be large. Therefore, while ensuring smooth oil intake, the atomizer thickness can be made smaller.

[0055] In this design, the atomizing assembly 2 includes a seal 22, a bracket 21, an oil guide 23, a heating element, a base 24, and an iron cover 25. The oil guide 23 can be made of soft cotton or hard porous ceramic, providing a planar atomizing surface and a liquid absorption surface. The heating element can be made of sheet metal through etching. The seal 22 can be made of silicone or rubber, and it is fitted onto the upper end of the bracket 21 and sealed to the inner wall of the oil cup 1. The base 24 is fixed to the bottom end of the bracket 21 and fixedly connected to the inner wall of the oil cup 1. A heating element is formed inside the bracket 21 located at the... The atomizing chamber on one side of the heating element is located on the other side of the atomizer's central axis relative to the second oil inlet channel 20. This allows the second oil inlet channel 20 to be made larger in the thickness direction of the atomizer. The base 24 is provided with an air inlet channel for external air to flow into the atomizing chamber. The oil guide body 23 is preferably vertically installed in the bracket 21 with its atomizing surface facing the atomizing chamber. The heating element is attached to the atomizing surface of the oil guide body 23 and electrically connected to two electrodes passing through the base 24. The iron cover 25 is installed at the bottom of the base 24 and fixed to the oil cup 1.

[0056] In practical applications, the oil guide 23 can also be tilted, meaning the angle between the oil guide 23 and the bottom surface of the atomizing component 2 can range from 60° to 120°. It should be understood that although tilting the oil guide 23 may result in a thickness greater than 7.7mm for the atomizer, under the structural design of this application, with a specific angle between the oil guide 23 and the bottom surface of the component, the ratio between the minimum width of the second oil inlet channel 20 in the thickness direction of the atomizer and the atomizer's dimension in the thickness direction can still be relatively large. In other words, under this specific angle, the structural design of this solution can achieve a smaller thickness compared to similar products.

[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.
