Description

Technical Field

[0001] This utility model relates to the field of electronic atomization equipment technology, and in particular to an atomization component, atomization module and atomizer. Background Technology

[0002] In the field of electronic atomizers, the main function of the atomizing component is to heat and atomize the e-liquid (such as nicotine-containing e-liquid or other aerosol-forming matrix) into an aerosol that can be inhaled by the user. In existing technology, traditional atomizers typically include an atomizing tube, an atomizing bracket, and an atomizing coil. The e-liquid enters the atomizing tube directly through an inlet port, coming into contact with the atomizing coil mounted on the bracket, and is then atomized by heating the coil. However, this traditional structure has significant drawbacks: to prevent e-liquid from leaking into the atomizing tube (atomizing airway) through the inlet port when the atomizer is not in use (such as during transportation or storage), it is usually designed so that the e-liquid and the atomizing coil do not come into pre-contact; and when the user uses it for the first time, the e-liquid often cannot quickly and completely wet the atomizing coil, leading to localized overheating of the coil and the production of a burnt-tasting aerosol, severely impacting the user's vaping experience.

[0003] To address the aforementioned burnt taste issue, an improved solution has been proposed in the prior art: an oil separator is added to the outside of the atomizing tube to isolate it from the liquid supply chamber, forming a closed liquid storage chamber between the oil separator and the atomizing tube. This storage chamber pre-stores an appropriate amount of atomizing liquid to ensure the atomizing core is fully soaked before use. While this structure addresses the burnt taste problem to some extent, it still has shortcomings in actual production and assembly: Firstly, the oil inlet holes on the oil separator and atomizing tube require manual alignment, which is inefficient and makes it difficult to ensure precise alignment, leading to uneven liquid supply. Secondly, due to the small overall size of the atomizing assembly, the atomizing tube is prone to tilting due to collisions when connected to the base, further causing misalignment of the oil inlet holes, resulting in poor liquid supply or leakage. Ultimately, this still affects the quality of aerosol generation and the user's inhalation experience. Utility Model Content

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.

[0019] In the description of this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0020] refer to Figures 1-8As shown, this application provides an atomizing component 10, which includes a base 11, an inner shell 12, an outer shell 13, and an atomizing core 14. The outer shell 13 is sleeved on the inner shell 12 and is mounted on the base 11 by a detachable positioning structure. The inner shell 12 defines an air passage for mounting the atomizing core 14. The atomizing core 14 atomizes the atomizing liquid in the air passage to generate an aerosol. Example 1

[0021] Both the outer shell 13 and the inner shell 12 of the atomizing assembly 10 have cylindrical structures. (Reference) Figures 2 to 5 As shown, a cylindrical outer shell 13 is fitted over a cylindrical inner shell 12. The inner shell 12 has a first oil inlet hole 120 on its side wall, and the outer shell 13 has a second oil inlet hole 130 on its side wall. When the outer shell 13 and the inner shell 12 are connected to the base 11, at least part of the holes of the first oil inlet hole 120 and the second oil inlet hole 130 overlap.

[0022] See Figure 4 As shown, the outer casing 13 is cylindrical with open openings at both the top and bottom. A second oil inlet 130 is provided on one side wall of the outer casing 13. The edge portion of the cylindrical wall below the second oil inlet 130 extends downwards along the axial direction perpendicular to the second oil inlet 130, protruding to form a plug 131. (Combined) Figure 2 and Figure 3 As shown, plug 131 is used to connect to base 11.

[0023] The plug 131 has a centerline Z1 extending upward along the cylinder axis, and the second oil inlet 130 has a centerline Z2 extending upward along the cylinder axis, with the centerline Z2 coinciding with the centerline Z1. When the plug 131 is connected to the base 11, the second oil inlet 130 has a fixed installation direction. It is understood that by ensuring the plug 131 and base 11 have a single installation direction, the housing 13 cannot rotate circumferentially on the base 11.

[0024] See Figure 5 As shown, the inner shell 12 is cylindrical with open openings at both the top and bottom. An air passage is formed within the cylinder. A first oil inlet 120, approximately at the same height as the second oil inlet 130, is provided on one side of the inner shell 12. A groove 121, extending upwards from the edge, is provided on the cylinder wall below the first oil inlet 120. Combined with... Figure 2 and Figure 3 As shown, the slot 121 is used to connect to the base 11.

[0025] The slot 121 has a centerline Z3 extending upward along the cylinder axis, and the second oil inlet 130 has a centerline Z4 extending upward along the cylinder axis, with the centerline Z4 coinciding with the centerline Z3. When the slot 121 is connected to the base 11, the first oil inlet 120 has a fixed installation direction. It is understood that the slot 121 and the base 11 share the same unique installation direction as the plug 131, preventing the inner shell 12 from rotating circumferentially on the base 11.

[0026] refer to Figure 6 and Figure 7 As shown, the base 11 is generally frustum-shaped, with an upper part of a small-diameter section and a lower part of a large-diameter section. An air inlet 110 penetrates the base 11, connecting the upper and lower end faces. The small-diameter section has a first outer diameter 111 that mates with the inner diameter of the inner shell 12, and the sidewall of the first outer diameter 111 has a locking protrusion 1110 that engages with the locking groove 121 on the sidewall of the inner shell 12. When the inner shell 12 is inserted into the small-diameter section, the sidewall of the small-diameter section at the locking protrusion 1110 forms part of the sidewall of the inner shell 12. The large-diameter section has a second outer diameter 112 that mates with the inner diameter of the outer shell 13, and a slot 1120 is provided on the sidewall of the second outer diameter 112. The plug 131 on the outer shell 13 is inserted into the slot 1120. Understandably, there is a radial drop between the slot wall of the slot 1120 and the latch protrusion 1110. When the outer shell 13 and the inner shell 12 are installed on the base 11, a liquid storage chamber 15 is formed between the outer shell 13 and the inner shell 12 to accommodate the atomizing liquid. The air passage is connected to the air inlet 110. The atomizing liquid stored in the liquid storage chamber 15 can enter the air passage through the first oil inlet 120 and come into contact with the atomizing core 14.

[0027] See Figure 7 As shown, the protrusion 1110 has a centerline Z5 along the thickness direction of the base 11, and the slot 1120 has a centerline Z6 along the thickness direction of the base 11, with the centerline Z6 coinciding with the centerline Z5. Furthermore, after the outer shell 13, inner shell 12, and base 11 are connected, the first oil inlet 120 and the second oil inlet 130 at least partially overlap. In some embodiments, the first oil inlet 120 and the second oil inlet 130 completely overlap. Of course, to control the supply efficiency of the atomizing liquid, there may be a size difference between the first oil inlet 120 and the second oil inlet 130, resulting in partial overlap. For example, the area of ​​the first oil inlet 120 may be greater than or equal to the area of ​​the second oil inlet 130.

[0028] Specifically, in some embodiments, the first oil inlet 120 extends circumferentially along the side wall of the inner shell 12, and the cross-section of the first oil inlet 120 is of a superior arc shape. The second oil inlet 130 extends circumferentially along the side wall of the outer shell 13, and the cross-section of the second oil inlet 130 is of a inferior arc shape. The area of ​​the first oil inlet 120 is larger than the area of ​​the second oil inlet 130, so that the atomizing liquid in the liquid storage chamber 15 can quickly wet the atomizing core 14, while the second oil inlet 130 can prevent a large amount of atomizing liquid from entering the liquid storage chamber 15. Example 2

[0029] See Figure 8 and Figure 9 As shown, an atomizing component 10 with a substantially similar structure to Embodiment 1 is provided. The difference lies in that, in this embodiment, a liquid storage medium 16 is disposed in the liquid storage chamber 15, and a liquid guiding medium 17 is disposed in the air passage. The liquid guiding medium 17 supports the atomizing core 14 and fixes it in the air passage. The liquid storage medium 16 is used to contain the atomized liquid through a microporous structure, and the liquid guiding medium 17 is used to draw the atomized liquid from the liquid storage chamber 15 through the first oil inlet 120 and transfer the drawn atomized liquid to the atomizing core 14.

[0030] In some embodiments, the liquid guiding medium 17 at least partially protrudes through the first oil inlet hole 120 and then extends into the liquid storage cavity 15 to contact the liquid storage medium 16.

[0031] The storage medium 16 and the guiding medium 17 can be made of the same material, such as plant cotton or synthetic cotton with capillary or microporous structures. To control the transmission efficiency of the atomizing liquid at different locations, the porosity of the storage medium 16 and the guiding medium 17 can be the same or different.

[0032] Combining the two embodiments described above, the atomizing core 14 has a liquid-absorbing surface and an atomizing surface. The liquid-absorbing surface is close to the inner wall of the inner shell 12 and near the first oil inlet 120. When the atomizing liquid is immersed, the liquid-absorbing surface can quickly absorb the atomizing liquid. In some embodiments, in order to generate more aerosol, the area of ​​the liquid-absorbing surface is greater than or equal to the area of ​​the first oil inlet.

[0033] On the other hand, this application provides an atomizing module 100, including a base 20 and an atomizing component 10 as described in any of the above embodiments. The base 20 is provided with a countersunk hole 21, and a positioning groove 22 is provided on one side of the small diameter section of the countersunk hole 21 along the height of the hole wall. At least part of the outer shell 13 connected to the second positioning structure is inserted into the positioning groove 22.

[0034] like Figures 10 to 12 An atomizing module 100 has a base 20 and an atomizing component 10 as described in the above embodiment. The base 20 has a countersunk hole 21, which has a large-diameter section at the top and a small-diameter section at the bottom. The large-diameter section is adapted to the outer shell 13. For example... Figure 11 As shown, the large-diameter section can accommodate a portion of the lower part of the outer casing 13, the small-diameter section penetrates the base 20, and a positioning groove 22 is provided on one side of the hole wall of the small-diameter section, which is set along the height of the hole wall. Figure 12 As shown, after the plug 131 of the outer shell 13 of the atomizing component 10 is inserted into the slot 1120, part of the plug 131 passes through the slot 1120 and is inserted into the positioning slot 22. The air passage is connected to the small diameter section of the countersunk hole 21. The atomizing component 10 and the base 20 are combined to form an atomizing module 100, forming a modular structure.

[0035] Understandably, the positioning groove 22 fits tightly with the plug 131, and the outer wall of the housing 13 fits against the inner wall of the large-diameter section of the countersunk hole 21. The atomizing assembly 10 can obtain structural rigidity to resist radial impact, so that the atomizing assembly 10 will not tilt during installation.

[0036] On the other hand, this application provides an atomizer 1, which includes an oil tank 30 and an atomizing module 100 as described in any of the above embodiments. The oil tank 30 has an opening on one side, and the base 20 is installed at the opening. The atomizing module 10, the base 20 and the oil tank 30 together form a liquid supply chamber 31, and the second oil inlet 130 communicates with the liquid supply chamber 31.

[0037] like Figure 13 and Figure 14 The atomizer 1 includes an oil tank 30 and an atomizing module 100. One end of the oil tank 30 is provided with an air outlet, and the other end opposite to the air outlet direction is provided with an open opening. The base 20 in the atomizing module 100 is installed at the open opening of the oil tank 30 to close the oil tank 30. The atomizing component 10 is installed on the side of the base 20 facing the inside of the oil tank 30. The outer tube is connected to the inner wall of the oil tank 30 and connects the air passage to the air outlet. The outer wall of the outer tube, the base 20, and the inner wall of the oil tank 30 together form a liquid supply chamber 31. The second oil inlet 130 is connected to the liquid supply chamber 31. The liquid supply chamber 31 is used to store more atomizing liquid. When in use, when external air passes through the air passage, a negative pressure is generated in the air passage, which causes the pressure in the liquid storage chamber 15 to be greater than that in the air passage. Some of the air and atomizing liquid in the liquid storage chamber 15 are immersed into the air passage through the first oil inlet 120 and come into contact with the atomizing core 14. Since the liquid supply chamber 31 is connected to the liquid storage chamber 15 through the second oil inlet 130, the atomizing liquid in the liquid supply chamber 31 is replenished into the liquid storage chamber 15 through the second oil inlet 130.

[0038] The above description is only a part or preferred embodiment of this utility model. Neither the text nor the drawings should limit the scope of protection of this utility model. All equivalent structural transformations made using the content of this utility model specification and drawings under the overall concept of this utility model, or direct / indirect applications in other related technical fields, are included within the scope of protection of this utility model.
