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 side wall; the liquid guiding element is disposed 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 a radially extending elongated portion; wherein 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 component having a through hole; the side wall of the liquid storage component having a groove communicating with the through hole; the atomizing sleeve is also sleeved within the through hole of the liquid storage component; the elongated portion is clamped in the groove, such that the two side walls of the groove are not closed due to the isolation provided by the elongated portion; and a shell, the side wall of the shell having a first liquid inlet hole; the groove and the elongated portion are aligned with the first liquid inlet hole.

[0006] In some embodiments, the end of the elongated portion is flush with the outer surface of the liquid reservoir.

[0007] In some embodiments, there is a gap between the end of the elongated portion and the outer surface of the liquid storage member, the gap being 0.1-2 mm in size, thereby forming a liquid storage gap by the two side walls of the groove and the end of the elongated portion, and the first liquid inlet hole communicating with the liquid storage gap.

[0008] In some embodiments, the elongated portion includes a first liquid-conducting layer and a second liquid-conducting layer that are superimposed, and a capillary gap is formed between the first liquid-conducting layer and the second liquid-conducting layer.

[0009] In some embodiments, the atomizing assembly further includes an outer liquid guiding layer, which wraps around the outside of the atomizing sleeve and the opposite sides of the first and second liquid guiding layers.

[0010] In some embodiments, the first liquid guiding layer and the second liquid guiding layer are of equal length along the radial direction;

[0011] Alternatively, the length of the first liquid guiding layer along the radial direction is greater than the length of the second liquid guiding layer along the radial direction, and a liquid storage micro-pool is formed between the first liquid guiding layer, the second liquid guiding layer and the outer liquid guiding layer, with the capillary pores communicating with the liquid storage micro-pool.

[0012] In some embodiments, the inner wall of the housing is interference-fitted with the liquid storage component, thereby squeezing the liquid storage component and causing the groove on the liquid storage component to shrink, thereby causing the capillary gap to be formed between the first liquid guiding layer and the second liquid guiding layer.

[0013] 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;

[0014] One 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.

[0015] 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;

[0016] The side wall of the atomizing sleeve is also provided with a second liquid inlet hole; the outer shell is also provided with a third liquid inlet hole, which is correspondingly arranged with the second liquid inlet hole, wherein the distance between the third liquid inlet hole and the second liquid inlet hole is less than the distance between the first liquid inlet hole and the limiting groove.

[0017] 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; a first liquid inlet communicating with the liquid storage chamber; and the liquid storage chamber supplying liquid to the liquid storage component and the extended portion of the liquid guiding component through the first liquid inlet.

[0018] 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.

[0019] 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 two side walls of the groove are not closed due to the isolation of the elongated portion, so the end of the elongated portion can be directly exposed on the outer side of the liquid storage component through the groove. Furthermore, when the groove and the elongated portion are aligned with the first liquid inlet hole on the side wall of the outer casing, the first liquid inlet... The liquid pores can directly guide the aerosol matrix to the elongated section, allowing the elongated section to directly absorb liquid and transport it to the heating element. This avoids the risk of reduced fragrance content caused by the elongated section absorbing the aerosol matrix filtered by the storage unit. It can effectively reduce the phenomenon of the aerosol matrix being filtered by the storage unit during transmission, thereby effectively reducing the degree of weakening of fragrance content in the aerosol matrix and reducing the risk of deterioration of the atomized taste. This is conducive to a more complete expression of the taste of the atomized aerosol. Attached Figure Description

[0032] This application provides an electronic atomizing device 200, 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.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] See also Figures 3 to 5 , Figure 3 Is it like this? Figure 2 A cross-sectional view of the atomizing core in the atomizer shown. Figure 4 Is it like this? Figure 3 The diagram shows the exploded structure of the atomizing core. Figure 5 Is it like this? Figure 3 The diagram shows the exploded structure of the atomizing component in the atomizing core.

[0042] 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.

[0043] 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.

[0044] Specifically, such as Figure 3 and Figure 5 As shown, the atomizing assembly 12 includes an atomizing sleeve 120, a heating element 122, and a liquid guiding element 124. The side wall of the atomizing sleeve 120 is provided with a limiting groove 121. 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.

[0045] The atomizing sleeve 120 has a tubular structure and a limiting groove 121 with a top opening is provided on its tube wall. 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] See also Figure 4 and Figure 6 ,in Figure 6Is it like this? Figure 3 The diagram shows an assembly structure of one embodiment of the liquid storage component, atomizing component, and base.

[0051] The liquid storage component 14 has a through hole 140, and the side wall of the liquid storage component 14 has a groove 142 communicating with the through hole 140. The atomizing sleeve 120 is also fitted inside the through hole 140 of the liquid storage component 14, and the extension 125 is clamped in the groove 142, so that the two side walls of the groove 142 are not closed due to the isolation of the extension 125. The side wall of the outer shell 16 has a first liquid inlet hole 161, and the groove 142 and the extension 125 are aligned with the first liquid inlet hole 161.

[0052] 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.

[0053] The length of the extension 125 refers to the length of the extension beyond the outer wall of the atomizing sleeve 120. The extension 125 is clamped in the groove 142, that is, the length of the extension 125 is not greater than the length of the groove 142 in the same direction, so that the groove 142 can completely clamp the extension 125.

[0054] The distance between the end of the elongated portion 125 and the outer side of the liquid storage component 14 is no greater than 2.0 mm. The distance between the end of the elongated portion 125 and the outer side of the liquid storage component 14 can be 0, 0.1 mm, 0.3 mm, 0.6 mm, 1.0 mm, 1.2 mm, 1.5 mm, 1.8 mm or 2.0 mm, etc. Within this distance range, the two side walls of the groove 142 can be kept open due to the isolation of the elongated portion 125.

[0055] In other words, such as Figure 6As shown, the end of the elongated portion 125 can be directly exposed on the outer side of the liquid storage component 14 through the groove 142. When the groove 142 and the elongated portion 125 are aligned with the first liquid inlet hole 161 on the side wall of the outer shell 16, the first liquid inlet hole 161 can directly guide the aerosol matrix in the liquid storage cavity 212 to the elongated portion 125. This allows the elongated portion 125 to directly absorb liquid from the liquid storage cavity 212 and transport it to the heating element 122. This avoids the risk of the fragrance component being reduced due to the elongated portion 125 absorbing the aerosol matrix filtered by the liquid storage component 14. It can effectively reduce the phenomenon that the aerosol matrix is ​​filtered by the liquid storage component 14 during transmission, thereby effectively reducing the degree of weakening of the fragrance component in the aerosol matrix, reducing the risk of deterioration of the atomized taste, and helping to make the taste of the atomized aerosol more fully expressed.

[0056] The liquid storage component 14 is made of polyester fiber, polypropylene fiber, or non-woven fabric, etc., and its material density is 0.01-0.1 g / cm³. 3 The liquid storage component 14, made of this material and with the specified density, has high and uniform adsorption capacity, enabling it to store 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 the liquid can be replenished to the atomizing component 12 in a timely manner, and the stored aerosol matrix can be prevented from overflowing. Furthermore, it has high temperature resistance and oxidation resistance, maintaining its properties at high temperatures and not releasing harmful substances during heating.

[0057] The liquid guiding component 124 is made of flax fiber or cotton fiber, etc., and the material density of the liquid guiding component 124 is 0.1-0.3 g / cm³. 3 The liquid guiding component 124, with its material and density specifications, is more compact than the liquid storage component 14, resulting in stronger and faster liquid and gas guiding capabilities. Therefore, it can supply liquid to the heating element 122 more promptly, compensating for the insufficient liquid supply in some scenarios caused by the material and density specifications of the liquid storage component 14. This makes the overall liquid supply to the heating element 122 more sufficient, effectively reducing the risk of dry burning.

[0058] In this embodiment, the liquid storage component 14 is used to store the aerosol matrix, which can lock the aerosol matrix and reduce its free flow. Its low material density reduces the adsorption of other flavoring substances in the aerosol matrix. The liquid guiding component 124 is used to conduct the aerosol matrix. Its high material density allows for a more efficient liquid supply relative to the liquid storage component 14, ensuring timely and sufficient liquid supply to the heating element 122 and preventing leakage caused by excessively fast aerosol matrix conduction. Since the elongated portion 125 is sandwiched in the groove 142 of the liquid storage component 14, the aerosol matrix can be directly and quickly conducted to the heating element 122 through the elongated portion 125 to participate in atomization, improving the aerosol's flavor and flavor reproduction.

[0059] See Figure 3 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.

[0060] 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.

[0061] like Figure 4 As shown, 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 respectively cover the opposite sides of the second liquid inlet 127. 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.

[0062] See also Figure 4 and Figure 7 , Figure 7 Is it like this? Figure 3 The diagram shows a cross-sectional view of another embodiment of the atomizing core. The outer shell 16 is also provided with a third liquid inlet 163, which is correspondingly arranged with the second liquid inlet 127. The distance between the third liquid inlet 163 and the second liquid inlet 127 is smaller than the distance between the first liquid inlet 161 and the limiting groove 121. Therefore, the air replenishment path from the air inlet gap 162 to the third liquid inlet 163 is relatively short, allowing for faster air replenishment to the liquid storage chamber 212 through the third liquid inlet 163, achieving a ventilation effect and preventing pressure imbalance in the liquid storage chamber 212.

[0063] Multiple first liquid inlet holes 161 may also 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.

[0064] The air conduction rate of the extension 125 is higher than that of the liquid storage component 14. Therefore, the air supplemented from the air inlet gap 162 can also be quickly supplemented into the liquid storage chamber 212 through the extension 125 to achieve the air exchange effect, making the liquid conduction smoother and avoiding dry burning.

[0065] In one embodiment, such as Figure 6 As shown, the end of the elongated portion 125 is flush with the outer surface of the liquid storage component 14, meaning the distance between the end of the elongated portion 125 and the outer surface of the liquid storage component 14 is 0. This maximizes the contact area between the liquid storage component 14 and the elongated portion 125, allowing the elongated portion 125 to absorb liquid more fully and quickly. It also reliably ensures timely and efficient liquid supply to the heating element 122, and the speed of aerosol matrix conduction is also faster. The elongated portion 125 can also directly abut against the first liquid inlet hole 161, so the aerosol matrix in the liquid storage cavity 212 can directly absorb liquid from the liquid storage cavity 212 and transport it to the heating element 122. This effectively avoids reducing the degree of weakening of the fragrance components in the aerosol matrix, reduces the risk of deterioration of the atomized taste, and helps to make the taste expression of the atomized aerosol more complete.

[0066] In another embodiment, such as Figure 7 As shown, there is a gap between the end of the elongated portion 125 and the outer surface of the liquid storage component 14. The size of the gap is 0.1-2 mm, that is, the gap is in the range of 0.1-2 mm. Thus, the liquid storage gap 126 is formed by the two side walls of the groove 142 and the end of the elongated portion 125. The liquid storage gap 126 is located opposite to the outer surface of the liquid storage component 14 and corresponds to the first liquid inlet hole 161. Therefore, the first liquid inlet hole 161 can directly communicate with the liquid storage gap 126, so that the liquid storage gap 126 can always be filled with aerosol matrix.

[0067] In other words, the liquid aerosol matrix can fully contact the end of the extension 125, so that the extension 125 can directly absorb the aerosol matrix, further improving the liquid conduction efficiency of the extension 125. This allows more aerosol matrix to be guided through the extension 125 to the heating element 122, which can more effectively reduce the degree of weakening of the flavor components in the aerosol matrix, reduce the risk of deterioration of the atomized taste, and help to make the taste of the atomized aerosol more fully expressed.

[0068] like Figure 6As shown, the elongated portion 125 includes a first liquid guiding layer 128 and a second liquid guiding layer 129 that are superimposed. A capillary gap 102 is formed between the first liquid guiding layer 128 and the second liquid guiding layer 129. The capillary gap 102 can further enhance the ability to guide liquid to the heating element 122 by utilizing the capillary effect. When the capillary gap 102 delivers the aerosol matrix, it can avoid adsorbing and intercepting the fragrance components therein, which is conducive to making the flavor expression of the aerosol generated by atomization more complete.

[0069] Based on the above embodiments, such as Figure 6 As shown, the end of the elongated portion 125 is flush with the outer surface of the liquid reservoir 14, and the capillary gap 102 can be directly connected to the first liquid inlet 161; or as shown... Figure 7 As shown, a liquid storage gap 126 is formed at the end of the elongated portion 125, and the capillary gap 102 is directly connected to the liquid storage gap 126.

[0070] In this embodiment, the inner wall of the outer shell 16 is pressurized to the liquid storage component 14, thereby compressing the liquid storage component 14 and causing the groove 142 on the liquid storage component 14 to shrink, thereby causing a capillary gap 102 to be formed between the first liquid guiding layer 128 and the second liquid guiding layer 129.

[0071] Specifically, the elongated portion 125 is engaged in the limiting groove 121, the cutting groove 142 clamps the elongated portion 125, and further, under the compression of the outer shell 16, a capillary gap 102 with a very small gap size is formed between the first liquid guiding layer 128 and the second liquid guiding layer 129. This capillary gap 102 is larger than the size of the pore structure in the liquid guiding component 124, so it can replenish the heating element 122 more efficiently under the capillary action it forms. Compared with the other positions of the liquid storage component 14 and the liquid guiding component 124, this capillary gap 102 can effectively avoid the flavor decay problem caused by the aerosol matrix passing through the liquid storage component 14, and improve the flavor reproduction of the aerosol.

[0072] It should be noted that the capillary gap 102 formed between the first liquid guiding layer 128 and the second liquid guiding layer 129 refers to the existence of this fine gap 102, and because of its existence, the liquid guiding rate at this position is faster than at other positions of the liquid storage component 14, and the blocking effect on the fragrance components is also lower. It does not mean that the first liquid guiding layer 128 and the second liquid guiding layer 129 are spaced apart and do not contact each other.

[0073] Among them, the size of the capillary pore 102 is 0.01-0.05mm. Within this size range, the capillary pore 102 has a more significant effect, a faster liquid conduction rate, and a smaller impact on flavor decay.

[0074] Optionally, such as Figure 6 or Figure 7As shown, the first liquid guiding layer 128 and the second liquid guiding layer 129 are of equal length along the radial direction of the atomizing sleeve 120. The ends of the first liquid guiding layer 128 and the second liquid guiding layer 129 are flush with the outer surface of the liquid storage component 14, or there is a gap between them and the outer surface of the liquid storage component 14. The size of the gap does not exceed 2.0 mm. Relatively speaking, the end of the elongated portion 125 has a larger liquid absorption area, which can improve the liquid guiding effect of the elongated portion 125 in the atomizing core 10, so as to improve the problem of flavor decay.

[0075] Please see Figure 8 , Figure 8 Is it like this? Figure 3 The diagram shows an assembly structure schematic of another embodiment of the liquid storage component, atomizing component, and base.

[0076] Optionally, the radial length of the first liquid guiding layer 128 is greater than the radial length of the second liquid guiding layer 129. The end of the first liquid guiding layer 128 may be flush with the outer surface of the liquid storage component 14, or there may be a gap between it and the outer surface of the liquid storage component 14, so that the end of the first liquid guiding layer 128 can be used to absorb liquid first, and then the first liquid guiding layer 128 and the second liquid guiding layer 129 can be combined to guide liquid, so as to appropriately control the liquid guiding rate.

[0077] Furthermore, the atomizing assembly 12 also includes an outer liquid guiding layer 123, which wraps around the outside of the atomizing sleeve 120 and the opposite sides of the first liquid guiding layer 128 and the second liquid guiding layer 129.

[0078] The outer liquid guiding layer 123 is made of the same material as the liquid guiding component 124, and further wraps around the atomizing sleeve 120 and the extension 125 to eliminate the leakage caused by the contact gap between the liquid storage component 14 and the atomizing sleeve 120.

[0079] When the radial length of the first liquid guiding layer 128 is greater than the radial length of the second liquid guiding layer 129, a liquid storage micro-pool 103 is formed between the first liquid guiding layer 128, the second liquid guiding layer 129 and the outer liquid guiding layer 123, and the capillary void 102 connects the liquid storage micro-pool 103.

[0080] When the liquid storage device 14 is saturated with liquid, the liquid storage micro-pool 103 is also filled with aerosol matrix. When the heating element 122 is in operation, the aerosol matrix in the liquid storage micro-pool 103 can be directly transferred through the elongated part 125 and its capillary gaps 102 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.

[0081] 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 two side walls of the groove are not closed due to the isolation provided by the elongated portion, allowing the end of the elongated portion to be directly exposed on the outer surface of the liquid reservoir through the groove. With the groove and the elongated portion aligned with the first liquid inlet hole on the side wall of the outer casing, this first inlet... The liquid pores can directly guide the aerosol matrix to the elongated section, allowing the elongated section to directly absorb liquid and transport it to the heating element. This avoids the risk of reduced fragrance content caused by the elongated section absorbing the aerosol matrix filtered by the storage unit. It can effectively reduce the phenomenon of the aerosol matrix being filtered by the storage unit during transmission, thereby effectively reducing the degree of weakening of fragrance content in the aerosol matrix and reducing the risk of deterioration of the atomized taste. This is conducive to a more complete expression of the taste of the atomized aerosol.

Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
