Benefits of technology

[0019] The technical solution of this utility model involves forming a ventilation channel between the second and first oil-guiding cotton, with the ventilation channel positioned close to the oil inlet. Because the ventilation channel can store gas and is itself a cavity, it significantly reduces the obstruction to the gas flow from the atomizing chamber to the oil inlet. Thus, when a negative pressure is created in the oil storage chamber, the gas in the atomizing chamber can quickly flow to the position near the oil inlet and then sequentially pass through the first oil-guiding cotton and the oil inlet into the oil storage chamber. This quickly restores the internal and external pressure balance of the oil storage chamber, achieving rapid ventilation and improving the ventilation speed. Furthermore, due to the small cross-sectional area of ​​the ventilation channel, oil cannot pass through it, thus preventing oil leakage into the cavity of the atomizing chamber and avoiding oil leakage.

Description

Technical Field

[0001] This utility model relates to the field of atomization technology, and in particular to an atomizing core, atomizing device, and atomizing equipment. Background Technology

[0002] Atomizing devices typically consist of an atomizing unit and a power supply unit that powers the atomizing unit. The atomizing unit usually contains an oil reservoir and an atomizing coil housed within the reservoir. An oil inlet is located between the oil reservoir and the atomizing coil, allowing the oil in the reservoir to flow through and be drawn into the atomizing coil. During use, the power supply unit powers the atomizing coil, causing it to convert the absorbed liquid into an aerosol for the user to inhale.

[0003] As the amount of oil in the reservoir decreases, a negative pressure is generated within it. Without ventilation, the oil cannot penetrate the porous ceramic atomizing core, easily leading to wicking. Therefore, ventilation of the reservoir is necessary, meaning the addition of gas. However, existing ventilation channels suffer from inadequate design, resulting in slow ventilation rates. Utility Model Content

[0004] The main purpose of this invention is to provide an atomizing core that solves the problem of slow air exchange speed in existing atomizing cores due to unreasonable design of the air exchange channel.

[0005] To achieve the above objectives, the atomizing core proposed in this utility model includes:

[0006] The atomizing tube has an atomizing chamber inside, and the tube wall has an oil inlet hole that connects the atomizing chamber to the outside.

[0007] The first oil-guiding cotton is installed in the atomizing chamber, and an installation cavity extending to both ends of the first oil-guiding cotton is formed inside. The outer peripheral wall abuts against the inner peripheral wall of the atomizing tube and blocks the inner side of the oil inlet hole.

[0008] A second oil-guiding cotton is inserted into the mounting cavity and surrounds the cavity wall to form a ventilation channel. At least one end of the ventilation channel is connected to the atomizing chamber. The ventilation channel is located near the oil inlet and has a cross-sectional area of ​​0.01–1 mm. 2 ;

[0009] The heating element is installed on the second oil-guiding cotton to fit against its inner wall.

[0010] Optionally, the downward orthographic projection of the oil inlet has a portion located in the same radial direction as the downward orthographic projection of the air exchange channel in the atomizing tube, so that the air exchange channel is directly opposite the oil inlet.

[0011] Optionally, there are multiple oil inlet holes, and the number of ventilation channels is the same as the number of oil inlet holes. Each oil inlet hole has an oil inlet hole directly opposite it.

[0012] Optionally, the ventilation channel is vertical; and / or, the ventilation channel extends to both ends of the second oil-guiding cotton.

[0013] Optionally, the outer peripheral wall of the second oil-guiding cotton is formed with a ventilation groove, and the cavity wall of the mounting cavity seals the opening of the ventilation groove to form the ventilation channel by surrounding the groove wall of the ventilation groove.

[0014] Optionally, the cross-section of the ventilation trough is triangular, and the width of the ventilation trough gradually increases from the bottom of the trough to the opening.

[0015] Optionally, the width of the opening of the ventilation slot is 0.2-1mm.

[0016] Optionally, the thickness of the second oil-wicking cotton is greater than the thickness of the first oil-wicking cotton, and / or the density of the second oil-wicking cotton is greater than the density of the first oil-wicking cotton.

[0017] This utility model also proposes an atomizing device, including an oil storage tank and the aforementioned atomizing core. The oil storage tank forms an oil storage cavity, the atomizing core is installed in the oil storage tank, and the oil inlet is connected to the oil storage cavity.

[0018] This utility model also proposes an atomizing device, including a power supply device and the aforementioned atomizing device, wherein the power supply device is used to provide electrical energy to the atomizing core.

[0019] The technical solution of this utility model involves forming a ventilation channel between the second and first oil-guiding cotton, with the ventilation channel positioned close to the oil inlet. Because the ventilation channel can store gas and is itself a cavity, it significantly reduces the obstruction to the gas flow from the atomizing chamber to the oil inlet. Thus, when a negative pressure is created in the oil storage chamber, the gas in the atomizing chamber can quickly flow to the position near the oil inlet and then sequentially pass through the first oil-guiding cotton and the oil inlet into the oil storage chamber. This quickly restores the internal and external pressure balance of the oil storage chamber, achieving rapid ventilation and improving the ventilation speed. Furthermore, due to the small cross-sectional area of ​​the ventilation channel, oil cannot pass through it, thus preventing oil leakage into the cavity of the atomizing chamber and avoiding oil leakage.

[0030] The following will mainly describe the specific structure of the atomizer core.

[0031] Reference Figures 1 to 3 In this embodiment of the utility model, the atomizing core includes:

[0032] The atomizing tube 100 has an atomizing chamber 101 inside, and the tube wall has an oil inlet 102 that connects the atomizing chamber 101 to the outside.

[0033] The first oil-guiding cotton 200 is installed in the atomizing chamber 101. An installation cavity 201 extending to both ends of the first oil-guiding cotton 200 is formed inside. The outer peripheral wall abuts against the inner peripheral wall of the atomizing tube 100 and blocks the inner side of the oil inlet hole 102.

[0034] The second oil-guiding cotton 300 is inserted into the mounting cavity 201 and surrounds the cavity wall of the mounting cavity 201 to form a ventilation channel 301. At least one end of the ventilation channel 301 is connected to the atomizing cavity 101. The ventilation channel 301 is located near the oil inlet 102, and the cross-sectional area of ​​the ventilation channel 301 is 0.01 to 1 mm. 2 ;

[0035] The heating element 400 is installed on the second oil-guiding cotton 300 to fit against its inner wall.

[0036] Specifically, in this embodiment, when the atomizing core is actually used, the oil in the oil storage chamber flows sequentially through the oil inlet 102 and the first oil-guiding cotton 200 to the second oil-guiding cotton 300. The heating element 400 heats up under the power supply of the power supply device, thereby transferring heat to the second oil-guiding cotton 300 that is in contact with it. After being heated, the second oil-guiding cotton 300 converts the oil it has absorbed into a mist for the user to inhale. As the amount of oil in the oil storage chamber decreases, a negative pressure is generated in the oil storage chamber. At this time, the gas in the atomizing chamber 101 can sequentially enter the oil storage chamber through the ventilation channel 301, the inside of the first oil-guiding cotton 200, and the oil inlet 102, replenishing the oil storage chamber with gas and quickly restoring the internal and external air pressure balance of the oil storage chamber, ensuring that the oil in the oil storage chamber can continue to flow from the oil inlet 102 to the atomizing core.

[0037] Among them, the cross-sectional area of ​​the ventilation channel 301 is relatively small, for example, it can be selected as 0.04mm. 2 0.09mm 2 0.36mm 2 0.64mm 2 1mm 2 Or other means, to prevent the oil from passing through the ventilation channel 301, thereby preventing the oil from leaking into the cavity of the atomizing chamber 101 and thus preventing oil leakage.

[0038] The technical solution of this utility model involves forming a ventilation channel 301 between the second oil-guiding cotton 300 and the first oil-guiding cotton 200. This ventilation channel 301 is positioned close to the oil inlet 102. Because the ventilation channel 301 can store gas and is itself a cavity, it significantly reduces the obstruction to the gas flow from the atomizing chamber 101 to the area near the oil inlet 102. Thus, when a negative pressure is formed in the oil storage chamber, the gas in the atomizing chamber 101 can quickly flow to the position near the oil inlet 102 and then sequentially pass through the first oil-guiding cotton 200 and the oil inlet 102 into the oil storage chamber. This quickly restores the internal and external air pressure balance in the oil storage chamber, achieving rapid ventilation and improving the ventilation speed. Furthermore, due to the small cross-sectional area of ​​the ventilation channel 301, oil cannot pass through it, thus preventing oil leakage into the cavity of the atomizing chamber 101 and avoiding oil leakage.

[0039] In some embodiments, the downward orthographic projection of the oil inlet 102 is partially located in the same radial direction as the downward orthographic projection of the ventilation channel 301 in the atomizing tube 100, so that the ventilation channel 301 is directly opposite the oil inlet 102. That is, the ventilation channel 301 is not located to the side of the oil inlet 102, but directly opposite the oil inlet 102, thereby shortening the distance between the ventilation channel 301 and the oil inlet 102, which shortens the gas flow path, allowing the gas in the ventilation channel 301 to quickly reach the oil storage chamber and improve the ventilation speed.

[0040] Furthermore, there are multiple oil inlet holes 102, and the number of ventilation channels 301 is the same as the number of oil inlet holes 102. Each oil inlet hole 102 has an opposite oil inlet hole 102. In this way, the ventilation area is increased on the one hand, and the ventilation angle is also increased on the other hand, so that the gas in the atomizing chamber 101 can be replenished into the oil storage chamber from different angles, thereby improving the ventilation speed.

[0041] In some embodiments, the ventilation channel 301 is vertical; and / or, the ventilation channel 301 extends to both ends of the second oil-guiding cotton 300. A vertical ventilation channel 301, compared to a curved ventilation channel 301, reduces chamfers, allowing for smoother gas flow and increasing gas flow velocity, thereby ultimately increasing the ventilation speed. The ventilation channel 301 extends to both ends of the second oil-guiding cotton 300, meaning that both ends of the ventilation channel 301 are connected to the cavity of the atomizing chamber 101, thereby increasing the communication area between the ventilation channel 301 and the cavity of the atomizing chamber 101, and increasing the air intake angle, allowing gas outside both ends of the second oil-guiding cotton 300 to enter the ventilation channel 301, thereby increasing the air intake velocity and ultimately increasing the ventilation speed.

[0042] Regarding the specific formation of the ventilation channel 301, in some embodiments, a ventilation groove 310 is formed on the outer peripheral wall of the second oil-guiding cotton 300, and the cavity wall of the mounting cavity 201 seals the opening of the ventilation groove 310 to form the ventilation channel 301 by surrounding the groove wall of the ventilation groove 310. In other embodiments, an air groove may be formed on the cavity wall of the mounting cavity 201, and the outer peripheral wall of the second oil-guiding cotton 300 may seal the opening of the air groove to surround the groove wall of the air groove to form the ventilation channel 301.

[0043] In some embodiments, the cross-section of the ventilation groove 310 is triangular, and the width of the ventilation groove 310 gradually increases from the bottom to the opening. Thus, compared to a square configuration, the triangular configuration creates a slope on the groove wall, which has a guiding effect, allowing the oil to be guided to the bottom of the ventilation groove 310 after passing through the first oil-guiding cotton 200. This ensures the bottom of the ventilation groove 310 remains moist, preventing localized clogging of the second oil-guiding cotton 300 after heating. The width of the opening of the ventilation groove 310 is 0.2-1 mm. For example, it can be 0.2 mm, 0.3 mm, 0.6 mm, 0.8 mm, 1 mm, or others. That is, the smaller width of the opening of the ventilation groove 310 prevents oil leakage from the opening, thus avoiding oil leakage.

[0044] In some embodiments, the thickness of the second oil-guiding cotton 300 is greater than the thickness of the first oil-guiding cotton 200. Since the ventilation groove 310 is disposed on the second oil-guiding cotton 300, the thickness of the second oil-guiding cotton 300 is set to be thicker to avoid deformation due to the opening of the groove, thereby ensuring the structural stability of the ventilation groove 310 and ensuring the ventilation effect.

[0045] In some embodiments, the density of the second oil-wicking cotton 300 is greater than the density of the first oil-wicking cotton 200. A higher density in the second oil-wicking cotton 300 improves its resistance to deformation, thereby ensuring its structural stability and, consequently, the structural stability of the ventilation groove 310, thus guaranteeing the ventilation effect. A lower density in the first oil-wicking cotton 200 results in larger micropores, facilitating gas passage and further improving the ventilation effect.

[0046] This utility model also proposes an atomizing device, which includes an oil storage chamber and an atomizing core. The oil storage chamber forms an oil storage cavity, and the atomizing core is installed in the oil storage chamber. The oil inlet 102 communicates with the oil storage cavity. The specific structure of the atomizing core is as described in the above embodiments. Since this atomizing device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

The power supply device is used to provide electrical energy to the atomizing core. The specific structure of the atomizing device is the same as described in the above embodiments. Since this atomizing device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
