Description

Technical Field

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

[0002] Electronic atomizing devices have become integrated into daily life, and more and more users have become accustomed to using them.

[0003] Currently on the market, many electronic atomizing devices produce atomizers that, during use, produce a poor-tasting aerosol with neither aroma nor sweetness, resulting in a very unpleasant experience for users. Utility Model Content

[0004] This application mainly provides an atomizing core, an atomizer, and an electronic atomizing device to solve the problem of poor atomization taste that often occurs during the use of the atomizer.

[0005] To solve the above-mentioned technical problems, one technical solution adopted in this application is to provide an atomizing core. The atomizing core includes: an atomizing assembly comprising an atomizing sleeve, a heating element, and a liquid guiding element. The atomizing sleeve has a limiting groove on its wall. The liquid guiding element is arranged around the outer periphery of the heating element, and the two ends of the liquid guiding element are tightly closed together in the circumferential direction to form an elongated portion extending radially. The heating element and the portion of the liquid guiding element surrounding the heating element are housed within the atomizing sleeve. The elongated portion extends outward from the limiting groove. A liquid storage element has a through hole. The side wall of the liquid storage element has a groove communicating with the through hole. The atomizing sleeve is also fitted within the through hole of the liquid storage element. The elongated portion is sandwiched in the groove. The outward extension length of the elongated portion is less than the length of the groove in the same direction, such that the portions of the two side walls of the groove not isolated by the elongated portion are closed. The end of the elongated portion and the two side walls of the groove form a liquid storage micro-pool.

[0006] In some embodiments, the distance between the liquid storage microcell and the outer surface of the liquid storage element along the radial direction is 0.1-5 mm.

[0007] In some embodiments, the elongated portion extends outward from the atomizing sleeve by a length of 1-10 mm.

[0008] In some embodiments, the atomizing core further includes a housing, the inner wall of which is interference-fitted with the liquid storage component to compress the liquid storage component, causing the groove on the liquid storage component to contract and close, forming a capillary gap between the two side walls of the closed groove, the capillary gap communicating with the liquid storage micro-pool.

[0009] In some embodiments, the size of the capillary slit is 0.001-0.15 mm.

[0010] In some embodiments, the sidewall of the housing is provided with a first liquid inlet, and the groove and the extension are aligned with at least one of the first liquid inlets.

[0011] In some embodiments, the atomizing core further includes a base, the base having an air inlet, one end of the atomizing sleeve being connected to the air inlet, the air inlet being used to supply air into the atomizing sleeve;

[0012] The bottom end of the outer shell is also embedded in the base, and the liquid storage component is located in the buffer cavity formed by the outer shell, the atomizing sleeve and the base.

[0013] In some embodiments, the other end of the atomizing sleeve is inserted into the mounting hole on the top of the housing, and there is an air inlet gap between the other end of the atomizing sleeve and the mounting hole, so as to supply air to the liquid storage component through the air inlet gap;

[0014] The atomizing sleeve is also provided with a second liquid inlet on its tube wall. The liquid guiding component and the liquid storage component cover the opposite sides of the second liquid inlet, and the liquid storage component also supplies liquid to the liquid guiding component through the second liquid inlet.

[0015] To solve the above-mentioned technical problems, another technical solution adopted in this application is to provide an atomizer. The atomizer includes: a liquid storage assembly, comprising a liquid storage shell, a connector, and a liquid storage base; the connector is located inside the liquid storage shell and connected to the mouthpiece of the liquid storage shell; the liquid storage base is connected to the end of the liquid storage shell opposite to the mouthpiece; and an atomizing core as described above, the atomizing core connecting the connector and the liquid storage base, thereby defining a liquid storage chamber within the liquid storage shell, the liquid storage chamber supplying liquid to the atomizing assembly.

[0016] To solve the above-mentioned technical problems, another technical solution adopted in this application is to provide an electronic atomizing device. The electronic atomizing device includes a main unit and an atomizer as described above, wherein the main unit is connected to the atomizer and supplies power to the atomizer.

[0017] The beneficial effects of this application are as follows: Unlike existing technologies, this application discloses an atomizing core, an atomizer, and an electronic atomizing device. By tightening and fitting the two ends of the liquid guide in the atomizing assembly to form an elongated portion, the elongated portion is engaged with the limiting groove of the atomizing sleeve and extends outward from the limiting groove. This increases the liquid-absorbing area of ​​the liquid guide through the extended portion, thereby enhancing the liquid supply capacity of the liquid guide to the heating element. The length of the extended portion is less than the length of the groove in the same direction, so the groove can completely clamp the extended portion. The extended portion does not completely separate the two side walls of the groove; the portions of the two side walls of the groove not separated by the extended portion close together, and then the ends of the extended portion and the groove... The two side walls of the tank are also surrounded by liquid storage micro-pools. When the liquid storage component is saturated, the liquid storage micro-pool can store a small amount of aerosol matrix. Since it can directly store liquid aerosol matrix, when the heating element is in operation, the aerosol matrix in the liquid storage micro-pool can be directly transferred through the extension to supply liquid to the heating element. This can effectively reduce the phenomenon that the aerosol matrix is ​​filtered by the liquid storage component during the transfer due to being absorbed by the liquid storage component. This can effectively reduce the degree of weakening of the fragrance components in the aerosol matrix and reduce the risk of deterioration of the atomized taste. Attached Figure Description

[0028] This application provides an electronic atomizing device 300, see reference. Figures 1 to 2 , Figure 1 This is a schematic diagram of an embodiment of the electronic atomizing device provided in this application. Figure 2 yes Figure 1 A schematic cross-sectional view of an embodiment of the atomizer in the electronic atomizing device shown.

[0029] The electronic atomizing device 300 includes a main unit 200 and an atomizer 100. The main unit 200 is connected to the atomizer 100 and supplies power to the atomizer 100.

[0030] The electronic atomizing device 300 can be used to atomize aerosol matrices such as e-liquid, medicinal liquid, or nutrient solution, that is, to atomize liquid aerosol matrices into aerosols for users to inhale. The main unit 200 can be detachably connected to the atomizer 100 and supply power to the atomizer 100, thus allowing the atomizer 100 to be replaced; alternatively, the main unit 200 and the atomizer 100 can be integrated into one unit and supply power to the atomizer 100. The atomizer 100 stores and atomizes the aerosol matrix to form an aerosol for the user to inhale.

[0031] The main unit 200 includes an electrically connected control element and a battery. The control element is also used to electrically connect to the atomizer 100 to identify the status information of the atomizer 100 and control the power supply to the atomizer 100 based on the identified status information.

[0032] See Figure 2 The atomizer 100 includes a liquid storage assembly 20 and an atomizing core 10. The liquid storage assembly 20 includes a liquid storage shell 21, a connector 22, and a liquid storage base 23. The connector 22 is located inside the liquid storage shell 21 and connected to the mouthpiece 210 of the liquid storage shell 21. The liquid storage base 23 is connected to the end of the liquid storage shell 21 away from the mouthpiece 210. The atomizing core 10 is connected to the connector 22 and the liquid storage base 23, thereby defining a liquid storage chamber 212 inside the liquid storage shell 21. The liquid storage chamber 212 is used to store the aerosol matrix and supply liquid to the atomizing assembly 12 of the atomizing core 10.

[0033] One end of the liquid storage housing 21 is provided with a suction nozzle 210, and the other end is an open end. The liquid storage base 23 can be connected to the open end by a sealing element, or the liquid storage base 23 can be glued or fused to the open end. The connector 22 is provided with an air passage 220. The connector 22 is connected to the suction nozzle 210, and the air passage on it is connected to the suction nozzle 210. The connector 22 can be screwed or embedded in the suction nozzle 210.

[0034] The top end of the atomizing core 10 can be embedded in the connector 22 through a sealing element, and the atomization channel 101 in the atomizing core 10 is connected to the air passage 220 on the connector 22; the bottom end of the atomizing core 10 can be connected to the liquid storage base 23 through another sealing element.

[0035] In this embodiment, the atomizing core 10 is detachable from the liquid storage assembly 20. The top of the atomizing core 10 is first assembled onto the connector 22, and then the liquid storage base 23 connects the open end of the liquid storage shell 21 and the bottom end of the atomizing core 10.

[0036] Optionally, the liquid storage assembly 20 can be assembled first, and then the atomizing core 10 can be connected to the connector 22 and the liquid storage base 23 along the pre-installed hole on the liquid storage base 23.

[0037] Please see Figure 3 and Figure 4 , Figure 3 Is it like this? Figure 2 The diagram shows a cross-sectional view of the atomizer core in the atomizer. Figure 4 Is it like this? Figure 3 The diagram shows the exploded structure of the atomizing core.

[0038] In this embodiment, the atomizing core 10 includes an atomizing component 12, a liquid storage component 14, a housing 16, and a base 18. One end of the atomizing component 12 is connected to the air inlet 180 of the base 18. The liquid storage component 14 is sleeved on the outer periphery of the atomizing component 12 and located on the base 18. The bottom end of the housing 16 is connected to the base 18, and the top end of the housing 16 is connected to the other end of the atomizing component 12. The liquid storage component 14 is housed in a buffer cavity 160 formed by the housing 16, the atomizing component 12, and the base 18.

[0039] The atomizing component 12 is provided with an aerosol channel 101 that connects to the air inlet 180. The atomizing component 12 is used to atomize the aerosol matrix to generate aerosol in the aerosol channel 101. The outer shell 16 is provided with a first liquid inlet 161. When the atomizing core 10 is installed in the liquid storage component 20, the first liquid inlet 161 connects to the liquid storage chamber 212. The aerosol matrix stored in the liquid storage chamber 212 enters the outer shell 16 through the first liquid inlet 161. The liquid storage component 14 is used to absorb the aerosol matrix. It can buffer the aerosol matrix and appropriately slow down the liquid supply rate of the aerosol matrix to the atomizing component 12, so as to avoid directly immersing the atomizing component 12 in the liquid storage chamber 212 that stores the aerosol matrix, thereby reducing the risk of leakage caused by the excessively fast liquid supply rate.

[0040] See also Figures 3 to 5 ,in Figure 5 Is it like this? Figure 3 The diagram shows the exploded structure of the atomizing component in the atomizing core.

[0041] Specifically, the atomizing assembly 12 includes an atomizing sleeve 120, a heating element 122, and a liquid guiding element 124. The atomizing sleeve 120 has a limiting groove 121 on its wall. The liquid guiding element 124 is arranged around the outer periphery of the heating element 122, and the two ends of the liquid guiding element 124 are tightened together in the circumferential direction to form an elongated portion 125 extending in the radial direction. The portion of the heating element 122 and the portion of the liquid guiding element 124 surrounding the heating element 122 are housed in the atomizing sleeve 120, and the elongated portion 125 extends outward from the limiting groove 121.

[0042] like Figure 4 and Figure 5 As shown, the atomizing sleeve 120 has a tubular structure, and its tube wall is provided with a limiting groove 121 with a top opening. The liquid guiding component 124 is wrapped around the heating component 122 and assembled together in the atomizing sleeve 120, and the extension 125 is engaged in the limiting groove 121 along the top opening.

[0043] The liquid guiding component 124 can be made of materials with excellent liquid absorption and guiding capabilities, such as cotton fiber or flax fiber. These materials also have a certain degree of elasticity. Before installation, its thickness is greater than the difference between the outer diameter of the heating element 122 and the inner diameter of the atomizing sleeve 120. Therefore, after being installed on the atomizing sleeve 120 together with the heating element 122, it can be fixed on the atomizing sleeve 120. The liquid guiding component 124 can be tightly combined with the atomizing sleeve 120 and the heating element 122 under the pressure of compression, which can prevent leakage at the joint and also provide good liquid supply to the heating element 122.

[0044] The heating element 122 atomizes an aerosol matrix. The heating element 122 can be a heating mesh, or it can include a porous substrate and a heating layer disposed on the porous substrate. The porous substrate can be a ceramic substrate or a glass substrate. The heating element 122 provides good support for the liquid guiding element 124, ensuring a tight bond with it.

[0045] The liquid guiding component 124 has a layered structure, which can be extended into a flat layer when unfolded. The unfolded length of the liquid guiding component 124 is greater than the circumference of the heating element 122. After the liquid guiding component 124 is arranged around the outer circumference of the heating element 122, the two ends of the liquid guiding component 124 along the circumference of the heating element 122 are tightened and attached to form an elongated portion 125 extending radially. The part of the liquid guiding component 124 that wraps around the heating element 122 is cylindrical to match the inner shape of the atomizing sleeve 120. This allows the liquid guiding component 124 to be tightly combined with the atomizing sleeve 120 and the heating element 122 after the heating element 122 and the part of the liquid guiding component 124 surrounding the heating element 122 are housed in the atomizing sleeve 120. This can prevent leakage due to gaps at the joint between the atomizing sleeve 120 and the liquid guiding component 124, and prevent scorching due to gaps at the joint between the liquid guiding component 124 and the heating element 122.

[0046] The liquid guiding component 124 is tightened at both ends to form an elongated portion 125, wherein the elongated portion 125 is engaged in the limiting groove 121, thereby preventing the aerosol matrix from leaking from the joint between the elongated portion 125 and the limiting groove 121; furthermore, the elongated portion 125 extends outward from the limiting groove 121 to increase the liquid-absorbing area of ​​the liquid guiding component 124 through the extended elongated portion 125, thereby enhancing the liquid supply capacity of the liquid guiding component 124 to the heating element 122.

[0047] See also Figure 3 , Figure 4 and Figure 6 ,in Figure 6 Is it like this? Figure 3 The diagram shows the assembly structure of the liquid storage component, atomizing assembly, and base in the atomizing core.

[0048] The liquid storage component 14 is provided with a through hole 140, and the side wall of the liquid storage component 14 is provided with a groove 142 communicating with the through hole 140. The atomizing sleeve 120 is also sleeved in the through hole 140 of the liquid storage component 14. The extension 125 is clamped in the groove 142, wherein the length of the extension 125 is less than the length of the groove 142 in the same direction, so that the parts of the two side walls of the groove 142 that are not isolated by the extension 125 are closed, and the end of the extension 125 and the two side walls of the groove 142 form a liquid storage micro pool 126.

[0049] like Figure 4 As shown, the liquid storage component 14 has a columnar structure. The outer contour of the cross-section of the column can be circular, elliptical, or racetrack-shaped. A through hole 140 is provided in the middle. A groove 142 communicating with the through hole 140 is provided around the side wall of the through hole 140, so that the extension 125 can be clamped by pulling open the groove 142. When the through hole 140 accommodates the atomizing sleeve 120, the groove 142 clamps the extension 125.

[0050] See Figure 4 and Figure 6 The length of the extension 125 refers to the length of the extension beyond the outer wall of the atomizing sleeve 120. This length is less than the length of the groove 142 in the same direction, so that the groove 142 can completely clamp the extension 125. The extension 125 does not completely separate the two side walls of the groove 142. The two side walls of the groove 142 that are not separated by the extension 125 are closed together. Furthermore, a liquid storage micro-pool 126 is formed by the end of the extension 125 and the two side walls of the groove 142.

[0051] When the liquid storage device 14 is saturated with liquid, the liquid storage micro-pool 126 can store a small amount of aerosol matrix. Since it can directly store liquid aerosol matrix, when the heating element 122 is in operation, the aerosol matrix in the liquid storage micro-pool 126 can be directly transferred through the extension part 125 to supply liquid to the heating element 122. This can effectively reduce the phenomenon that the aerosol matrix is ​​filtered by the liquid storage device 14 during transmission due to being absorbed by the liquid storage device 14. This can effectively reduce the degree of weakening of the fragrance components in the aerosol matrix and reduce the risk of deterioration of the atomized taste.

[0052] In this embodiment, the liquid storage component 14 is liquid storage cotton with a density of 0.01-0.15 g / cm³. 3The liquid storage cotton of this density specification has high and uniform adsorption capacity, enabling it to absorb a certain amount of aerosol matrix. It also has good liquid conductivity and a stable liquid conductivity rate, ensuring that the aerosol matrix can be smoothly transferred to the heating element 122. This means that it can replenish the liquid to the atomizing component 12 in a timely manner and prevent the absorbed aerosol matrix from overflowing. Furthermore, it has high temperature resistance and oxidation resistance, maintaining its properties at high temperatures and not releasing harmful substances during heating.

[0053] Specifically, the density of the liquid storage cotton can be 0.01 g / cm³. 3 0.02g / cm 3 0.03g / cm 3 0.04g / cm 3 0.05g / cm 3 0.06g / cm 3 0.07g / cm 3 0.08g / cm 3 0.09g / cm 3 0.1g / cm 3 0.11 g / cm 3 0.12g / cm 3 0.13g / cm 3 0.14 g / cm 3 Or 0.15g / cm 3 .

[0054] Extensive data analysis revealed that the density of the liquid storage cotton is higher than 0.15 g / cm³. 3 At this time, the resistance to the conductive aerosol matrix will be relatively large, resulting in a low liquid conduction rate and a significant interception effect on the aroma components of the aerosol matrix, making it impossible to fully supply liquid to the atomizing component 12, which easily leads to dry burning and flavor deterioration; the density of the liquid storage cotton is less than 0.01 g / cm³. 3 When the adsorption capacity decreases, the risk of leakage increases significantly, and the liquid conduction rate becomes too fast, which can easily lead to excessive liquid supply to the atomizing component 12 and leakage.

[0055] Therefore, in the range of 0.01-0.15 g / cm 3 The liquid storage cotton of the specified specifications has a strong adsorption capacity for aerosol matrix, a stable and high liquid conduction rate, and a small interception effect on the aroma components in the aerosol matrix, resulting in good taste reproduction of the aerosol generated by atomization.

[0056] In other embodiments, the liquid reservoir 14 may also be made of nonwoven fabric, flax fiber, polyester fiber, and polypropylene fiber, etc.

[0057] Continue reading Figure 4 and Figure 6The elongated portion 125 extends radially outward along the atomizing sleeve 120, wherein the distance between the liquid storage micro-pool 126 and the outer surface of the liquid storage component 14 along this radial direction is 0.1-5mm. That is, the liquid storage micro-pool 126 is located relatively in the peripheral area of ​​the liquid storage component 14, closer to the side wall of the outer shell 16, wherein the side wall of the outer shell 16 is provided with a first liquid inlet hole 161, so that the aerosol matrix entering the outer shell 16 can pass through a shorter path to enter the liquid storage micro-pool 126, and can further directly supply liquid to the heating element 122 through the elongated portion 125, so that the aerosol generated by atomization has a higher degree of flavor reproduction, better atomization expression, and improved flavor consistency.

[0058] Optionally, the distance between the liquid storage micro-pool 126 and the outer surface of the liquid storage component 14 in the radial direction can be 0.1mm, 0.3mm, 0.5mm, 0.8mm, 1.0mm, 1.5mm, 2.0mm, 2.6mm, 3.0mm, 3.5mm, 4.0mm, 4.6mm or 5mm.

[0059] The extension portion 125 extends outward from the atomizing sleeve 120 by a length of 1-10 mm, and its extension can be 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, or 10 mm. The extension of the extension portion 125 is greater than 1 mm, so that it can be reliably clamped by the limiting groove 121; the extension of the extension portion 125 is less than 10 mm, so as to avoid the side walls of the groove 142 not being able to close due to excessive length, so that under the current commonly used atomizer 100 specifications and dimensions, a clear liquid storage micropool 126 can be formed, so that the aerosol matrix stored in the liquid storage micropool 126 can improve the taste reproduction of the aerosol.

[0060] Continue reading Figure 3 , Figure 4 and Figure 6 In this embodiment, the inner wall of the outer shell 16 is pressurized to fit the liquid storage component 14, thereby squeezing the liquid storage component 14 and causing the groove 142 on the liquid storage component 14 to shrink and close. A capillary gap 144 is formed between the two side walls of the closed groove 142, and the capillary gap 144 connects to the liquid storage micro pool 126.

[0061] Compared to the integrated structure of the rest of the liquid storage component 14, there is still a noticeable capillary gap 144 between the closed portions of the two side walls of the groove 142. The size of this capillary gap 144 is larger than the size of the pore structure on the liquid storage component 14, making the aerosol matrix more likely to reach the liquid storage micro-pool 126 directly through this capillary gap 144. This allows for more efficient and faster replenishment of the liquid storage micro-pool 126. Therefore, the aerosol matrix provided from the liquid storage chamber 212 can be supplied to the heating element 122 more efficiently and timely through the liquid supply path formed by the capillary gap 144, the liquid storage micro-pool 126, and the extension 125. Compared to other locations on the liquid storage component 14, this liquid supply path can also reduce the flavor degradation caused by the aerosol matrix passing through the liquid storage component 14, thereby improving the flavor reproduction of the aerosol.

[0062] Because the size of the capillary slit 144 is still within the range of tiny sizes, the aerosol matrix can form a capillary effect on it, thereby enabling the aerosol matrix to pass through the capillary slit 144 more efficiently and quickly to replenish the liquid in the liquid storage micro-pool 126.

[0063] It should be noted that the capillary gap 144 formed between the closed portions of the two side walls of the groove 142 refers to the existence of the capillary gap 144, and the fact that its existence causes the liquid conduction rate at this position to be faster than at other positions of the liquid storage component 14, and the blocking effect on the fragrance components is also lower, rather than saying that the closed portions of the two side walls of the groove 142 are isolated and do not contact each other.

[0064] Among them, the size of the capillary slit 144 is 0.001-0.15mm. Within this size range, the capillary slit 144 has a more significant effect, a faster liquid conduction rate, and a smaller impact on flavor decay.

[0065] Furthermore, such as Figure 3 and Figure 4 As shown, the groove 142 and the extension 125 are both aligned with at least one first liquid inlet hole 161, so that the distance between the first liquid inlet hole 161 at this position and the liquid storage micro tank 126 and the extension 125 is the closest, and the liquid can be supplied to the liquid storage micro tank 126 more directly and effectively.

[0066] In other words, the first liquid inlet 161 at this location is directly connected to the capillary slit 144, so that the aerosol matrix through the first liquid inlet 161 can efficiently supply liquid to the liquid storage micro-pool 126.

[0067] Multiple first liquid inlet holes 161 may be provided circumferentially on the side wall of the outer casing 16. The groove 142 and the extension 125 may be aligned with at least one of the first liquid inlet holes 161, and the remaining first liquid inlet holes 161 directly supply liquid to the liquid storage component 14.

[0068] like Figure 3As shown, in this embodiment, one end of the atomizing sleeve 120 is connected to the air inlet 180 of the base 18, and the air inlet 180 is used to supply air to the atomizing channel 101 inside the atomizing sleeve 120; the bottom end of the outer shell 16 can also be embedded in the base 18 through a sealing member, and the liquid storage member 14 is located in the buffer cavity 160 formed by the outer shell 16, the atomizing sleeve 120 and the base 18.

[0069] The other end of the atomizing sleeve 120 is inserted into the mounting hole on the top of the outer shell 16, and there is an air inlet gap 162 between the other end of the atomizing sleeve 120 and the mounting hole, so as to supply air to the liquid storage component 14 through the air inlet gap 162, and finally replenish the liquid storage cavity 212 through the first liquid inlet hole 161, so as to avoid the liquid flow obstruction caused by the imbalance of internal and external air pressure of the atomizer 100.

[0070] See also Figure 3 and Figure 4 The atomizing sleeve 120 is also provided with a second liquid inlet 127 on its tube wall. The liquid guide 124 and the liquid storage component 14 cover opposite sides of the second liquid inlet 127, respectively. The liquid storage component 14 also supplies liquid to the liquid guide 124 through the second liquid inlet 127, so that the liquid supply to the liquid guide 124 is more uniform and timely. There can be two or three second liquid inlets 127, which are distributed along the circumference of the atomizing sleeve 120.

[0071] Unlike existing technologies, this application discloses an atomizing core, an atomizer, and an electronic atomizing device. By tightening and fitting the two ends of a liquid guide member into an elongated portion within the atomizing assembly, the elongated portion is engaged with a limiting groove in the atomizing sleeve and extends outward from the limiting groove. This increases the liquid-absorbing area of ​​the liquid guide member, thereby enhancing its liquid supply capacity to the heating element. The extended length is less than the length of the groove in the same direction, allowing the groove to completely hold the elongated portion. The elongated portion does not completely separate the two side walls of the groove; the portions of the two side walls not separated by the elongated portion close together, and the ends of the elongated portion and the groove... The two side walls of the tank are also surrounded by liquid storage micro-pools. When the liquid storage component is saturated, the liquid storage micro-pool can store a small amount of aerosol matrix. Since it can directly store liquid aerosol matrix, when the heating element is in operation, the aerosol matrix in the liquid storage micro-pool can be directly transferred through the extension to supply liquid to the heating element. This can effectively reduce the phenomenon that the aerosol matrix is ​​filtered by the liquid storage component during the transfer due to being absorbed by the liquid storage component. This can effectively reduce the degree of weakening of the fragrance components in the aerosol matrix and reduce the risk of deterioration of the atomized taste.
