Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, specifically to an atomizing core assembly and atomizing device. Background Technology

[0002] Atomizing devices consist of a liquid reservoir and an atomizing coil assembly. The reservoir stores the atomized liquid, while the coil atomizes it for the user to inhale. Generally, the coil assembly includes a heating element and a liquid guide covering the heating element. One possible type of liquid guide is wicking cotton. The atomized liquid from the reservoir permeates the guide and reaches the heating element, allowing it to be heated and atomized. This permeation process is called coil lubrication. Atomizing devices typically require adding atomized liquid to the reservoir before use and waiting for lubrication before vaping. Therefore, a lubrication time is required after adding liquid, which, with traditional coil assemblies, is relatively long, impacting the user experience. Utility Model Content

[0028] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0029] This application provides an atomizing device; please refer to [reference needed]. Figure 1 and Figure 2The atomizing device includes a housing 10, which is a split structure comprising a main body 101 and a bottom cover 102. The inner cavity of the main body 101 forms a chamber for installing various functional components and containing the atomizing liquid. The bottom end of the main body 101 has an opening, and the bottom cover 102 is assembled and connected to the bottom end of the main body 101, thereby sealing the opening at the bottom end of the main body 101. The top of the main body 101 is provided with an atomizing nozzle 103, which has a suction channel 1031.

[0030] An air inlet 104 is provided on one side of the main body 101, and a liquid injection hole 105 is provided on the opposite side. Atomizing liquid can be added to the atomizing device through the liquid injection hole 105. Correspondingly, the atomizing device also includes a hole seal 20 for plugging the liquid injection hole 105. After the liquid is injected into the atomizing device through the liquid injection hole 105, the hole seal 20 can be used to plug the liquid injection hole 105 to prevent leakage. The composition of the atomizing liquid is prior art and will not be described in detail here.

[0031] The outer casing 10 houses an atomizer core assembly 30, a power supply 40, and a PCBA assembly 50. PCBA, or Printed Circuit Board Assembly, is a functional circuit board with pre-soldered components, directly enabling electronic functions. The outer casing 10 also includes an airflow regulator 60, positioned corresponding to the air inlet 104, allowing for airflow adjustment. The power supply 40 is connected to the PCBA assembly 50 for signal transmission. The bottom cover 102 has a charging structure 90 electrically connected to the power supply 40.

[0032] The atomizer core assembly 30 is used to heat the atomizing liquid to atomize it. For details on the structure of the atomizer core assembly 30, please refer to [link to relevant documentation]. Figure 3 and Figure 4 The atomizing core assembly 30 includes an atomizing bracket 301, a heating element 302, a first liquid guiding element 303, a second liquid guiding element 304, and an atomizing cover 305.

[0033] In some embodiments, please refer to Figure 5 The atomizing support 301 has a cylindrical structure, and its inner cavity forms an airflow channel 3011 for airflow to pass through. A second liquid inlet channel 3012 is provided on the atomizing support 301. The atomizing support 301 can be a cylindrical structure or other cylindrical structures, such as those with an elliptical or hexagonal cross-section.

[0034] Please refer to all factors. Figure 3 and Figure 4 The heating element 302 is a heating wire mesh structure. The heating wire mesh is arranged in a cylindrical structure within the airflow channel 3011, and the inner cavity of the cylindrical structure formed by the heating wire mesh allows airflow to pass through. Please refer to [reference needed]. Figure 2The heating element 302 is electrically connected to the power supply 40. The power supply 40 supplies power to the heating element 302, enabling the heating function of the heating element 302. The atomizing core assembly 30 also includes a plastic base 306 disposed in the airflow channel 3011. The plastic base 306 serves as a fixing member for fixing the pins of the heating element 302.

[0035] Please refer to Figure 3 The first liquid guiding element 303 is partially located within the airflow channel 3011 and covers the periphery of the heating element 302. In some embodiments, the atomizing support 301 also has a notch structure 3013, and the first liquid guiding element 303 has an ear portion 3031, which is inserted into the notch structure 3013 and extends to the outside of the atomizing support 301. The first liquid guiding element 303 can be permeated by the atomizing liquid, thereby allowing the atomizing liquid to penetrate the heating element 302. Since it is in direct contact with the heating element 302, the first liquid guiding element 303 also needs to have high temperature resistance. One feasible approach is to use liquid-guiding cotton to make the first liquid guiding element 303.

[0036] Please refer to Figure 3 The atomizing cover 305 is disposed outside the atomizing support 301, and a gap exists between the atomizing cover 305 and the atomizing support 301. In some embodiments, please refer to... Figure 6 The atomizing cover 305 is also a cylindrical structure, with a first liquid inlet channel 3051 on it. The atomizing cover 305 is fitted over the outside of the atomizing support 301, creating an annular gap between them. A second liquid guiding element 304 is disposed within the gap between the atomizing cover 305 and the atomizing support 301. The second liquid guiding element 304 can also be permeated by the atomizing liquid. The atomizing cover 305 can be a cylindrical structure or other cylindrical structures, such as those with an elliptical or hexagonal cross-section.

[0037] Please refer to Figure 2 The atomizing core assembly 30 is installed inside the outer casing 10. A liquid storage chamber 70 for storing atomizing liquid is formed between the atomizing outer cover 305 of the atomizing core assembly 30 and the outer casing 10. The injection port 105 communicates with the liquid storage chamber 70. When starting to use the atomizing device, add atomizing liquid into the liquid storage chamber 70 through the injection port 105. Please refer to... Figure 3 As indicated by the middle arrow, the atomizing liquid can enter the second liquid guide 304 through the first liquid inlet channel 3051. The atomizing liquid permeates the second liquid guide 304 and can enter the first liquid guide 303 through the second liquid inlet channel 3012. The atomizing liquid can then soak into the heating element 302 after it has permeated the first liquid guide 303. The power supply 40 supplies power to the heating element 302, so that the heating element 302 can heat and atomize the atomizing liquid.

[0038] The direction of airflow within the airflow channel 3011 is defined as the first direction. The atomizing device will be described below with the first direction as the up-down direction. The top mentioned above is the upper part, and the bottom is the lower part. During suction, the airflow flows from bottom to top within the airflow channel 3011.

[0039] To improve the speed of wicking with atomizing liquid, the upper end of at least one first liquid inlet channel 3051 is not lower than the upper end of the first liquid guide 303, and the lower end of at least one first liquid inlet channel 3051 is not higher than the lower end of the first liquid guide 303. In this way, the first liquid inlet channel 3051 on the atomizing cover 305 can cover the first liquid guide 303, increasing the liquid inlet area of ​​the atomizing liquid, improving the liquid inlet efficiency, and enabling the atomizing liquid to wet the first liquid guide 303 more quickly through the first liquid inlet channel 3051, thereby improving the wicking speed and shortening the waiting time for the user to start using the atomizing device.

[0040] Regarding the structure of the first liquid inlet channel 3051, please refer to some embodiments. Figure 6 The first liquid inlet channel 3051 includes an elongated hole 3052 formed on the atomizing outer cover 305. In some other embodiments, a plurality of elongated holes 3052 are formed on the atomizing outer cover 305, the length of each elongated hole 3052 extends along a first direction, and the plurality of elongated holes 3052 are evenly spaced along the circumference of the cylindrical atomizing outer cover 305.

[0041] Please take the exam. Figure 3 The upper end of each elongated hole 3052 is higher than the upper end of the first liquid guiding component 303, and the lower end of each elongated hole 3052 is lower than the lower end of the first liquid guiding component 303, so that the upper end of each first liquid inlet channel 3051 is higher than the first liquid guiding component 303, and the lower end is lower than the lower end of the first liquid guiding component 303.

[0042] In some other embodiments, the elongated holes 3052 can be arranged in an alternating manner, such that the upper end of one elongated hole 3052 is higher than the first liquid guiding member 303, and the lower end of the elongated hole 3052 is also higher than the lower end of the first liquid guiding member 303. The upper end of the adjacent elongated hole 3052 is lower than the lower end of the first liquid guiding member 303, and the lower end of the elongated hole 3052 is lower than the lower end of the first liquid guiding member 303. In this way, the upper end of at least one first liquid inlet channel 3051 is higher than the first liquid guiding member 303, and the lower end of at least one first liquid inlet channel 3051 is lower than the first liquid guiding member 303. In some other embodiments, the atomizing cover 305 may also be provided with only one elongated hole 3052, the upper end of which is at the same height as or higher than the upper end of the first liquid guide 303, and the lower end of which is at the same height as or lower than the lower end of the first liquid guide 303.

[0043] Regarding the amount by which the upper end of the first liquid inlet channel 3051 extends above the upper end of the first liquid guide 303, in some embodiments, the upper end of the first liquid inlet channel 3051 extends above the upper end of the first liquid guide 303 by 1.5 mm. Of course, in other embodiments, the amount by which the upper end of the first liquid inlet channel 3051 extends above the upper end of the first liquid guide 303 can be greater than 1.5 mm, such as 2 mm, or less than 1.5 mm, such as 1 mm.

[0044] In some other embodiments, the upper end of the first liquid inlet channel 3051 may be at the same height as the upper end of the first liquid guide 303, and the lower end of the first liquid inlet channel 3051 may be at the same height as the lower end of the first liquid guide 303.

[0045] In some other embodiments, the structure of the atomizing cover 305 is described in reference. Figure 7 and Figure 8 Multiple liquid inlet holes 3053 are provided on the atomizing outer cover 305, and each liquid inlet hole 3053 constitutes a first liquid inlet channel 3051.

[0046] In some embodiments, the plurality of liquid inlet holes 3053 on the atomizing cover 305 are divided into multiple groups of liquid inlet holes. Each group of liquid inlet holes includes a plurality of liquid inlet holes 3053 arranged in the vertical direction. The upper end of the liquid inlet hole 3053 located at the uppermost end of each group of liquid inlet holes is not lower than the upper end of the first liquid guiding member 303, and the lower end of the liquid inlet hole 3053 located at the lowermost end is not higher than the lower end of the first liquid guiding member 303.

[0047] Please refer to Figure 7 A liquid inlet group contains three liquid inlets 3053. The uppermost liquid inlet 3053 is higher than the uppermost liquid guide 303, and the lowermost liquid inlet 3053 is located entirely below the first liquid guide 303. In some other embodiments, the number of liquid inlets 3053 in the liquid inlet group can be greater than three, such as four, five or even more, or less than three, such as two. Of course, the multiple liquid inlets 3053 on the atomizing cover 305 can also be randomly distributed, with at least one liquid inlet 3053 having an upper end that is not lower than, i.e., at the same height as, or higher than, the upper end of the first liquid guide 303, and at least one liquid inlet 3053 having a lower end that is not higher than, i.e., at the same height as, or lower than, the lower end of the first liquid guide 303.

[0048] For the inlet hole group, to ensure a faster liquid inlet speed, the orifice area of ​​the lowest inlet hole 3053 in each inlet hole group is larger than that of the other inlet holes 3053 in the same inlet hole group. When the atomizing device is placed vertically, the pressure is greatest at the lowest inlet hole 3053 in the inlet hole group. Setting the orifice area of ​​the lowest inlet hole 3053 to be the largest can increase the speed at which the atomizing liquid enters the atomizing core assembly 30. Furthermore, when the atomizing liquid is almost used up, the larger orifice area of ​​the lowest inlet hole 3053 facilitates the entry of the remaining small amount of atomizing liquid into the atomizing core assembly 30. Of course, in some other embodiments, while ensuring a suitable liquid inlet speed, the orifice areas of all inlet holes 3053 in the inlet hole group can also be the same.

[0049] In some embodiments, please refer to Figure 7 and Figure 8 Each liquid inlet hole 3053 is a circular hole. In other embodiments, the liquid inlet hole 3053 may also be other shapes, such as rectangular holes, triangular holes, etc. In some embodiments, the orifice area of ​​each liquid inlet hole 3053 in each group of liquid inlets gradually increases from top to bottom. In other embodiments, the orifice area of ​​the liquid inlet hole 3053 at the bottom of the group of liquid inlets may be larger than the orifice area of ​​the other liquid inlet holes 3053 in the same group. Except for the bottom liquid inlet hole 3053, the orifice areas of the other liquid inlet holes 3053 in the same group of liquid inlets are the same. In other embodiments, the first liquid inlet channel 3051 may also be a groove structure formed on the atomizing cover 305, such as extending the elongated hole 3052 in the above embodiments upward or downward and penetrating to the end of the atomizing cover 305 to form a groove structure.

[0050] Please refer to Figure 2 and Figure 3 The atomizing core assembly 30 also includes a sealing element disposed in the gap between the atomizing bracket 301 and the atomizing outer cover 305. This sealing element is a lower sealing element 307. The lower end of the second liquid guiding element 304 is located lower than the lower end of the first liquid guiding element 303. The lower sealing element 307 is disposed on the lower side of the second liquid guiding element 304 to seal the lower port of the gap between the atomizing bracket 301 and the atomizing outer cover 305 to prevent liquid leakage.

[0051] To ensure that the atomizing liquid in the storage tank 70 can be fully utilized, in some embodiments, the lower end of the first liquid inlet channel 3051 is not only lower than the lower end of the first liquid guide 303, but also lower than the lower end of the second liquid guide 304, and higher than the lower end of the lower seal 307, but the protrusion is between 0.5-2.5mm, such as 1mm or 2mm, so that as much atomizing liquid in the storage tank 70 as possible can enter the atomizing core assembly 30 through the first liquid inlet channel 3051.

[0052] In some embodiments, along the circumferential direction of the atomizing bracket 301 and the atomizing cover 305, the size of the second liquid inlet channel 3012 on the atomizing bracket 301 is larger than the size of the first liquid inlet channel 3051 on the atomizing cover 305, so that the second liquid inlet channel 3012 has a larger flow area, which facilitates the atomized liquid in the second liquid guide 304 to enter the first liquid guide 303 through the second liquid inlet channel 3012.

[0053] Please refer to all factors. Figure 2 and Figure 3 The atomizing nozzle 103 has a double-layer structure, with the inner layer forming a suction channel 1031. The atomizing device also includes an upper sealing member 80 disposed between the inner and outer layers of the atomizing nozzle 103. The upper ends of the atomizing bracket 301 and the second liquid guiding member 304 are lower than the upper end of the atomizing outer cover 305. The upper end of the atomizing outer cover 305 is sealed and inserted into the upper sealing member 80. The upper end of the second liquid guiding member 304 abuts against the upper sealing member 80, so that the suction channel 1031 is connected to the airflow channel 3011. When the atomizing nozzle 103 is drawn in, the air entering the outer shell 10 through the air inlet 104 can enter the airflow channel 3011 and flow from bottom to top in the airflow channel 3011, carrying the atomized liquid heated and atomized by the heating element 302 into the suction channel 1031, and finally inhaled by the user.

[0054] This application also provides an atomizing core assembly, which has the same structure as the atomizing core assembly 30 of the atomizing device in the above embodiments, and will not be described in detail here.

[0055] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
