[0034] The electronic atomization device 300 includes a host 200 and an atomizer 100 , wherein the host 200 is connected to the atomizer 100 and supplies power to the atomizer 100 .

[0035] The electronic atomization device 300 can be used to atomize aerosol substrates such as cigarette liquid, liquid medicine or nutrient solution, that is, to atomize the liquid aerosol substrate to form an aerosol for the user to inhale. Among them, the host 200 can be detachably connected to the atomizer 100 and power the atomizer 100, so that the atomizer 100 can be replaced; or the host 200 and the atomizer 100 are an integrated structure and power the atomizer 100. The atomizer 100 is used to store the aerosol substrate and atomize the aerosol substrate to form an aerosol for the user to absorb.

[0036] The host 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 status information of the atomizer 100 and control the power supply to the atomizer 100 according to the identified status information.

[0037] See also Figure 2 The atomizer 100 includes a liquid storage component 20 and an atomizer core 10, wherein the liquid storage component 20 includes a liquid storage shell 21, a connector 22 and a liquid storage base 23, the connector 22 is located in the liquid storage shell 21 and connected to the suction nozzle 210 of the liquid storage shell 21, and the liquid storage base 23 is connected to the end of the liquid storage shell 21 away from the suction nozzle 210; the atomizer core 10 is connected to the connector 22 and the liquid storage base 23, thereby defining a liquid storage cavity 212 in the liquid storage shell 21, and the liquid storage cavity 212 is used to store aerosol matrix and supply liquid to the atomizer component 12 of the atomizer core 10.

[0038] One end of the liquid storage housing 21 is provided with a suction nozzle 210, and the other end thereof is an open end, and the liquid storage base 23 can be connected to the open end through a sealing member, or the liquid storage base 23 is bonded or welded to the open end. An air passage 220 is provided in the connecting member 22, and the connecting member 22 is connected to the suction nozzle 210, and the air passage thereon is connected to the suction nozzle 210, wherein the connecting member 22 can be screwed or embedded in the suction nozzle 210.

[0039] The top end of the atomizer core 10 can be embedded in the connector 22 through a seal, and the aerosol channel 101 in the atomizer core 10 is connected to the airway 220 on the connector 22; the bottom end of the atomizer core 10 can be connected to the liquid storage base 23 through another seal.

[0040] In this embodiment, the atomizer core 10 is detachable relative to the liquid storage assembly 20 . The top end of the atomizer core 10 is first assembled on the connecting member 22 , and then the liquid storage base 23 is connected to the open end of the liquid storage housing 21 and the bottom end of the atomizer core 10 .

[0041] Optionally, the liquid storage assembly 20 may be assembled first, and then the atomizer core 10 is connected to the connecting member 22 and the liquid storage base 23 along the pre-assembled hole on the liquid storage base 23 .

[0042] Combined with reference Figures 3 to 5 , Figure 3 Yes Figure 2 The schematic diagram of the cross-sectional structure of the atomizer core in the atomizer shown in FIG. Figure 4 Yes Figure 3 The explosion structure diagram of the atomizer core is shown in FIG. Figure 5 Yes Figure 3 Schematic diagram of the explosion structure of the atomization component in the atomization core shown.

[0043] In this embodiment, the atomizer core 10 includes an atomizer assembly 12, a liquid storage component 14, a shell 16 and a base 18. One end of the atomizer assembly 12 is connected to the air inlet hole 180 of the base 18. The liquid storage component 14 is sleeved on the outer periphery of the atomizer assembly 12 and is located on the base 18. The bottom end of the shell 16 is connected to the base 18, and the top end of the shell 16 is connected to the other end of the atomizer assembly 12. The liquid storage component 14 is accommodated in a cache cavity 160 formed by the shell 16, the atomizer assembly 12 and the base 18.

[0044] Among them, the atomizer component 12 is provided with an aerosol channel 101 connected to the air inlet hole 180, and the atomizer component 12 is used to atomize the aerosol matrix to generate an aerosol in the aerosol channel 101; the shell 16 is provided with a first liquid inlet hole 161, and when the atomizer core 10 is installed on the liquid storage component 20, the first liquid inlet hole 161 is connected to the liquid storage cavity 212, and the aerosol matrix stored in the liquid storage cavity 212 enters the shell 16 through the first liquid inlet hole 161; the liquid storage component 14 is used to absorb and store the aerosol matrix, which can buffer the aerosol matrix and appropriately slow down the liquid supply rate of the aerosol matrix to the atomizer component 12, so as to avoid directly immersing the atomizer component 12 in the liquid storage cavity 212 storing the aerosol matrix, thereby reducing the risk of leakage caused by an excessively fast liquid supply rate.

[0045] Specifically, Figure 3 and Figure 5 As shown, the atomizer assembly 12 includes an atomizer sleeve 120, a heating element 122 and a liquid guiding element 124. The side wall of the atomizer 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 along the circumferential direction are tightly fitted to form an extension portion 125 extending radially, wherein the heating element 122 and the portion of the liquid guiding element 124 surrounding the heating element 122 are accommodated in the atomizer sleeve 120, and the extension portion 125 extends outward from the limiting groove 121.

[0046] The atomizing sleeve 120 is a tubular structure, and a limiting groove 121 with a top opening is provided on its tube wall. The liquid guide 124 wraps the heating element 122 and is assembled in the atomizing sleeve 120 together, and the extension portion 125 is clamped in the limiting groove 121 along the top opening.

[0047] Among them, the liquid guiding member 124 can be made of materials such as cotton fiber or linen fiber with excellent liquid absorption and liquid conducting capabilities. These materials also have a certain elasticity. The thickness before installation 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 member 124 can be tightly combined with the atomizing sleeve 120 and the heating element 122 under the extrusion force, which can prevent leakage at the joint and also achieve good liquid supply to the heating element 122.

[0048] The heating element 122 generates heat to atomize the aerosol matrix, wherein the heating element 122 may be a heating net, or the heating element 122 includes a porous matrix and a heating layer disposed on the porous matrix, wherein the porous matrix may be a ceramic matrix or a glass matrix. The heating element 122 may provide good support for the liquid guide 124 to be closely combined with the liquid guide 124.

[0049] The liquid guiding member 124 has a layered structure, which can be extended into a flat layer in the expanded state, and the expanded length of the liquid guiding member 124 is greater than the circumference of the heating element 122. After the liquid guiding member 124 is arranged around the outer circumference of the heating element 122, the two ends of the liquid guiding member 124 along the circumference of the heating element 122 are tightened and fitted to form an extension portion 125 extending radially, wherein the portion of the liquid guiding member 124 wrapping the heating element 122 is cylindrical to match the inner shape of the atomizing sleeve 120, so that after the heating element 122 and the portion of the liquid guiding member 124 surrounding the heating element 122 are accommodated in the atomizing sleeve 120, the liquid guiding member 124 can be tightly combined with the atomizing sleeve 120 and the heating element 122, which can prevent leakage due to a gap at the joint between the atomizing sleeve 120 and the liquid guiding member 124, and prevent burning due to a gap at the joint between the liquid guiding member 124 and the heating element 122.

[0050] The two ends of the liquid guiding member 124 are tightened and fitted to form an extension portion 125, wherein the extension portion 125 is clamped in the limiting groove 121, thereby preventing the aerosol matrix from leaking from the joint between the extension portion 125 and the limiting groove 121; further, the extension portion 125 extends outward from the limiting groove 121 to increase the liquid absorbable area of ​​the liquid guiding member 124 through the extended extension portion 125, so as to enhance the liquid supply capacity of the liquid guiding member 124 to supply liquid to the heating element 122.

[0051] Combined with reference Figure 4 and Figure 6 ,in Figure 6 Yes Figure 3 The figure shows a schematic diagram of the assembly structure of a liquid storage component, an atomization component and a base in one embodiment.

[0052] The liquid storage part 14 is provided with a through hole 140, and the side wall of the liquid storage part 14 is provided with a groove 142 connected with the through hole 140. The atomizing sleeve 120 is also sleeved in the through hole 140 of the liquid storage part 14, and the extension part 125 is clamped in the groove 142, wherein the distance between the end of the extension part 125 and the outer side surface of the liquid storage part 14 is not greater than 2.0 mm, and the two side walls of the groove 142 are not closed due to the isolation of the extension part 125. The side wall of the housing 16 is provided with a first liquid inlet hole 161, and the groove 142 and the extension part 125 are aligned with the first liquid inlet hole 161.

[0053] like Figure 4 As shown, the liquid storage member 14 is columnar in structure, and the outer contour of the cross-section of the column can be circular, elliptical or racetrack-shaped, with a through hole 140 penetrating therethrough in the middle, and a groove 142 communicating with the through hole 140 is provided on the side wall surrounding the through hole 140, so that the extension portion 125 can be clamped by pulling open the groove 142, and the groove 142 clamps the extension portion 125 when the through hole 140 accommodates the atomizer sleeve 120.

[0054] The extended length of the extension portion 125 refers to the length thereof exceeding the outer wall surface of the atomizing sleeve 120. The extension portion 125 is clamped in the groove 142, that is, the extended length of the extension portion 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 portion 125.

[0055] Among them, the distance between the end of the extension portion 125 and the outer side surface of the liquid storage component 14 is not greater than 2.0 mm, and the distance between the end of the extension portion 125 and the outer side surface 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 not closed due to the isolation of the extension portion 125.

[0056] In other words, if Figure 6 As shown, the end of the extension portion 125 can be directly exposed to the outer side of the liquid storage component 14 through the groove 142, and when the groove 142 and the extension portion 125 are aligned with the first liquid inlet hole 161 on the side wall of the shell 16, the first liquid inlet hole 161 can directly guide the aerosol matrix in the liquid storage chamber 212 to the extension portion 125, so that the extension portion 125 is equivalent to being able to directly absorb liquid from the liquid storage chamber 212 and transport it to the heating element 122, avoiding the risk of reducing the flavor components therein due to the extension portion 125 absorbing the aerosol matrix filtered by the liquid storage component 14, and can effectively reduce the phenomenon that the aerosol matrix is ​​filtered by the liquid storage component 14 during transmission due to being absorbed by the liquid storage component 14, thereby effectively reducing the degree of weakening of the flavor components in the aerosol matrix, reducing the risk of causing deterioration of the atomization taste, and facilitating a fuller expression of the taste of the aerosol generated by atomization.

[0057] The liquid storage member 14 is made of polyester fiber, polypropylene fiber or non-woven fabric, and the material density of the liquid storage member 14 is 0.01-0.1 g / cm 3 The liquid storage component 14 of this material and density specification has high and uniform adsorption capacity, can absorb a certain amount of aerosol matrix, and also has good liquid conduction ability and stable liquid conduction rate, ensuring that the aerosol matrix can be smoothly transmitted to the heating element 122, that is, it can replenish the atomization component 12 in time and avoid the overflow of the absorbed aerosol matrix; and it also has the characteristics of high temperature resistance and oxidation resistance, can maintain stable properties at high temperatures, and will not release harmful substances during the heating process.

[0058] The material of the liquid guide 124 is linen fiber or cotton fiber, and the material density of the liquid guide 124 is 0.1-0.3g / cm 3The liquid-conducting member 124 with this material and density specification is tighter than the liquid storage member 14, and has stronger liquid and gas conducting capabilities and a faster speed, so it can supply liquid to the heating element 122 more timely, making up for the problem of insufficient liquid supply in some scenarios caused by the material and density specifications of the liquid storage member 14, making the overall liquid supply to the heating element 122 more sufficient, and effectively reducing the risk of dry burning.

[0059] In this embodiment, the liquid storage member 14 is used to store the aerosol matrix, which can lock the aerosol matrix and reduce the free flow of the aerosol matrix. Its material density is low, which can reduce the adsorption of other flavor substances in the aerosol matrix. The liquid guide member 124 is used to conduct the aerosol matrix. Its material density is high, and the liquid supply speed can be appropriately increased relative to the liquid storage member 14, so as to timely and fully supply liquid to the heating element 122, and avoid leakage caused by the excessively fast conduction speed of the aerosol matrix. Since the extension portion 125 is clamped in the groove 142 of the liquid storage member 14, the aerosol matrix can be directly conducted to the heating element 122 through the extension portion 125 to participate in atomization, thereby improving the taste of the aerosol and the degree of flavor reduction.

[0060] See also Figure 3 In this embodiment, one end of the atomizer sleeve 120 is connected to the air inlet hole 180 of the base 18, and the air inlet hole 180 is used to supply air to the aerosol channel 101 in the atomizer sleeve 120; the bottom end of the shell 16 can also be embedded in the base 18 through a seal, and the liquid storage part 14 is located in the buffer cavity 160 formed by the shell 16, the atomizer sleeve 120 and the base 18.

[0061] The other end of the atomizer sleeve 120 is inserted into the assembly hole on the top of the shell 16, and there is an air intake gap 162 between the other end of the atomizer sleeve 120 and the assembly hole, so as to supply air to the liquid storage component 14 through the air intake gap 162, and finally replenish air into the liquid storage chamber 212 through the first liquid inlet hole 161, so as to avoid poor liquid flow due to the imbalance of internal and external air pressure of the atomizer 100.

[0062] like Figure 4 As shown, a second liquid inlet hole 127 is further provided on the tube wall of the atomizing sleeve 120, and the liquid guide member 124 and the liquid storage member 14 are respectively covered on opposite sides of the second liquid inlet hole 127, and the liquid storage member 14 also supplies liquid to the liquid guide member 124 through the second liquid inlet hole 127, so that the liquid supply to each part of the liquid guide member 124 is more uniform and timely. Among them, the second liquid inlet holes 127 can be two or three, etc., and are distributed along the circumference of the atomizing sleeve 120.

[0063] Combined with reference Figure 4 and Figure 7 , Figure 7 Yes Figure 3A schematic cross-sectional view of another embodiment of the atomizer core is shown. A third liquid inlet hole 163 is also provided on the housing 16, and the third liquid inlet hole 163 is arranged corresponding to the second liquid inlet hole 127, wherein the distance between the third liquid inlet hole 163 and the second liquid inlet hole 127 is smaller than the distance between the first liquid inlet hole 161 and the limiting groove 121, so that the air supply path from the air intake gap 162 to the third liquid inlet hole 163 is relatively short, and air can be supplied to the liquid storage chamber 212 more quickly through the third liquid inlet hole 163 to achieve a ventilation effect and avoid air pressure imbalance in the liquid storage chamber 212.

[0064] A plurality of first liquid inlet holes 161 may also be circumferentially disposed on the side wall of the housing 16 . The groove 142 and the extension portion 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 element 14 .

[0065] The air conduction rate of the extension portion 125 is higher than that of the liquid storage component 14, so the air replenished from the air intake gap 162 can also be quickly replenished into the liquid storage chamber 212 with the help of the extension portion 125 to achieve a ventilation effect, making the liquid conduction smoother and avoiding dry burning.

[0066] In one embodiment, if Figure 6 As shown, the end of the extension portion 125 is flush with the outer side surface of the liquid storage component 14, that is, the distance between the end of the extension portion 125 and the outer side surface of the liquid storage component 14 is 0, which can maximize the contact area between the liquid storage component 14 and the extension portion 125, so that the extension portion 125 can absorb liquid more fully and faster, and can reliably ensure timely and efficient liquid supply to the heating element 122, and the speed of conducting the aerosol matrix can also be faster; the extension portion 125 can also directly abut against the first liquid inlet hole 161, so that 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, which can effectively avoid reducing the degree of weakening of the flavor components in the aerosol matrix, reduce the risk of causing deterioration of the atomization taste, and help to make the aerosol generated by atomization express the taste more fully.

[0067] In another embodiment, if Figure 7 As shown, there is a gap between the end of the extension portion 125 and the outer side surface of the liquid storage component 14, and the gap is not less than 0.1 mm, that is, the gap size is in the range of 0.1-2 mm, so that a liquid storage gap 126 is formed by the two side walls of the groove 142 and the end of the extension portion 125. The liquid storage gap 126 is relatively located on the outer side surface of the liquid storage component 14 and corresponds to the first liquid inlet hole 161. Therefore, the first liquid inlet hole 161 can be directly connected to the liquid storage gap 126, so that the liquid storage gap 126 can always be filled with aerosol matrix.

[0068] In other words, the liquid aerosol matrix can fully contact the end of the extension portion 125, so that the extension portion 125 can directly absorb the aerosol matrix, further improving the liquid conduction efficiency of the extension portion 125, so that more aerosol matrix can be guided to the heating element 122 through the extension portion 125, which can more effectively reduce the degree of weakening of the flavor components in the aerosol matrix, reduce the risk of deterioration of the atomization taste, and help to make the taste of the aerosol generated by atomization more fully expressed.

[0069] like Figure 6 As shown, the extension portion 125 includes a first liquid conducting layer 128 and a second liquid conducting layer 129 stacked on each other, and a capillary gap 102 is formed between the first liquid conducting layer 128 and the second liquid conducting layer 129. The capillary gap 102 can utilize the capillary effect to further enhance the ability to conduct liquid to the heating element 122, and the capillary gap 102 can avoid adsorbing and intercepting the flavor components therein when transporting the aerosol matrix, which is beneficial to make the taste of the aerosol generated by atomization more fully expressed.

[0070] Based on the above embodiments, Figure 6 As shown, the end of the extension portion 125 is flush with the outer side of the liquid storage member 14, and the capillary gap 102 can be directly connected to the first liquid inlet hole 161; or Figure 7 As shown, a liquid storage gap 126 is formed at the end of the extension portion 125 , and the capillary gap 102 is directly connected to the liquid storage gap 126 .

[0071] In this embodiment, the inner wall surface of the shell 16 is interference fit with the liquid storage member 14, thereby squeezing the liquid storage member 14, causing the groove 142 on the liquid storage member 14 to shrink, thereby prompting the capillary gap 102 to be formed between the first liquid conductive layer 128 and the second liquid conductive layer 129.

[0072] Specifically, the extension portion 125 is clamped in the limiting groove 121, the cutting groove 142 clamps the extension portion 125, and further under the extrusion of the outer shell 16, a capillary gap 102 with an extremely small gap size is formed between the first liquid conducting layer 128 and the second liquid conducting layer 129. The capillary gap 102 is larger than the size of the pore structure in the liquid conducting component 124, so under the capillary action formed thereby, the heating component 122 can be replenished with liquid more efficiently. Compared with the rest of the positions of the liquid storage component 14 and the liquid conducting component 124, the capillary gap 102 can effectively avoid the taste attenuation problem of the aerosol matrix due to passing through the liquid storage component 14, thereby improving the taste restoration of the aerosol.

[0073] It should be noted that the capillary gap 102 formed between the first liquid conducting layer 128 and the second liquid conducting layer 129 refers to the existence of the fine gap 102, and due to its existence, the liquid conduction rate at this position is faster than that at other positions of the liquid storage part 14, and the blocking effect on the fragrance components is also lower, rather than that the first liquid conducting layer 128 and the second liquid conducting layer 129 are separated and not in contact with each other.

[0074] The capillary gap 102 has a gap size of 0.01-0.05 mm. Within this size range, the capillary gap 102 has a more significant effect, a faster liquid conduction rate, and a smaller impact on flavor attenuation.

[0075] Alternatively, if Figure 6 or Figure 7 As 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, and the ends of the first liquid guiding layer 128 and the second liquid guiding layer 129 are flush with the outer side surface of the liquid storage component 14, or there is a gap with the outer side surface of the liquid storage component 14, and the size of the gap does not exceed 2.0 mm. Relatively speaking, the end of the extension portion 125 has a larger liquid absorption area, which can enhance the liquid guiding effect of the extension portion 125 in the atomizing core 10 to improve the problem of flavor attenuation.

[0076] See also Figure 8 , Figure 8 Yes Figure 3 The figure shows a schematic diagram of the assembly structure of another embodiment of the liquid storage component, the atomization component and the base.

[0077] Optionally, the radial length of the first liquid conducting layer 128 is greater than the radial length of the second liquid conducting layer 129, wherein the end of the first liquid conducting layer 128 can be flush with the outer side of the liquid storage component 14, or there is a gap with the outer side of the liquid storage component 14, so that the end of the first liquid conducting layer 128 is first used to absorb liquid, and then the first liquid conducting layer 128 and the second liquid conducting layer 129 are combined to conduct liquid, so as to appropriately control the liquid conduction rate.

[0078] Furthermore, the atomizing assembly 12 further includes an outer liquid guiding layer 123 , which is wrapped around the outer side of the atomizing sleeve 120 and the two opposite sides of the first liquid guiding layer 128 and the second liquid guiding layer 129 .

[0079] The material of the outer liquid guiding layer 123 is the same as that of the liquid guiding member 124 , and further wraps the atomizing sleeve 120 and the extension portion 125 to eliminate the phenomenon of liquid leakage caused by the contact gap between the liquid storage member 14 and the atomizing sleeve 120 .

[0080] 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 microcell 103 is formed by the first liquid guiding layer 128 , the second liquid guiding layer 129 and the outer liquid guiding layer 123 , and the capillary gap 102 is connected to the liquid storage microcell 103 .

[0081] When the liquid storage component 14 is saturated with liquid, the liquid storage microcell 103 is also filled with aerosol matrix. When the heating element 122 is operating, the aerosol matrix in the liquid storage microcell 103 can be directly transmitted through the extension portion 125 and the capillary gaps 102 thereon to supply liquid to the heating element 122. This can effectively reduce the phenomenon of the aerosol matrix being filtered by the liquid storage component 14 during transmission due to being absorbed by the liquid storage component 14, thereby effectively reducing the degree of weakening of the flavor components in the aerosol matrix and reducing the risk of deteriorating the taste of the atomization.

[0082] Different from the prior art, the present application discloses an atomization core, an atomizer and an electronic atomization device. An extension portion is formed by tightening and fitting the two ends of the liquid guide member in the atomization assembly. The extension portion is clamped in the limiting groove of the atomization sleeve and extends outward from the limiting groove, so as to increase the liquid-absorbable area of ​​the liquid guide member through the extended extension portion, so as to enhance the liquid supply capacity of the liquid guide member to the heating element; wherein the distance between the end of the extension portion and the outer side surface of the liquid storage member is not greater than 2.0 mm, and the two side walls of the groove are not closed due to the isolation of the extension portion, so that the end of the extension portion can be directly exposed to the outer side surface of the liquid storage member through the groove, and the groove and the extension portion are aligned with the side wall of the outer shell. In the case of the first liquid inlet hole on the extension part, the first liquid inlet hole can directly guide the aerosol matrix to the extension part, so that the extension part can directly absorb liquid and transport it to the heating element, avoiding the risk of reducing the flavor components therein due to the extension part absorbing the aerosol matrix filtered by the liquid storage part, and can effectively reduce the phenomenon that the aerosol matrix is ​​filtered by the liquid storage part during transmission due to being absorbed by the liquid storage part, thereby effectively reducing the degree of weakening of the flavor components in the aerosol matrix, reducing the risk of causing deterioration of the atomization taste, and helping to make the taste of the aerosol generated by atomization more fully expressed.

Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
