The heating element is located on the side of the first liquid guide facing away from the heating base and is used to heat and atomize the aerosol-generating substrate to form an aerosol. During assembly, the second liquid guide is typically assembled manually. Specifically, one finger presses down on one end of the second liquid guide, and then another finger wraps the second liquid guide around the outer wall of the heating base.

[0052] The present application is described in detail below with reference to the accompanying drawings and embodiments.

[0053] See also Figure 1 , Figure 1 This is a schematic diagram of the structure of an electronic atomization device provided in one embodiment of the present application. In this embodiment, an electronic atomization device 100 is provided. This electronic atomization device 100 can be used to atomize an aerosol-generating substrate to form an aerosol for user inhalation. The aerosol-generating substrate can be a plant leaf substrate or a paste-like substrate. Specifically, the electronic atomization device 100 includes an atomizer 101 and a power supply assembly 102.

[0054] The atomizer 101 can be used in various fields, such as medical atomization, electronic atomization, or hairdressing.

Specifically, the atomizer 101 can be any of the following embodiments. The specific structure and function of the atomizer 101 can be described in the following embodiments. The atomizer 101 can achieve the same or similar technical effects, as described below.

[0055] The power supply assembly 102 is connected to the atomizer 101 and is used to supply power to the atomizer 101. The atomizer 101 and the power supply assembly 102 may be detachably connected to facilitate replacement of the atomizer 101 and improve the utilization of the power supply assembly 102. Of course, in other embodiments, the power supply assembly 102 and the atomizer 101 may also be integrally provided, and this application is not limited thereto.

[0056] Please refer to Figure 2a and Figure 2b , Figure 2a A schematic structural diagram of an atomizer provided in one embodiment of the present application; Figure 2b for Figure 2a In this embodiment, an atomizer 101 is provided, which includes a housing 10 and an atomizer core 20. Furthermore, the atomizer 101 may also include a mounting seat and a sealing member.

[0057] The housing 10 has a receiving cavity, within which the atomizer core 20 is disposed. The atomizer core 20 cooperates with the inner wall of the housing 10 to form a liquid storage cavity 30 for storing an aerosol-generating substrate. In a specific embodiment, the atomizer core 20 is configured to heat and atomize the aerosol-generating substrate from the liquid storage cavity 30 to form an aerosol when powered.

[0058] The atomizer core 20 may be any of the following embodiments. For its specific structure and function, please refer to the following description of the atomizer core 20 , and the same or similar technical effects can be achieved.

[0059] See also Figures 3 to 8 ,in, Figure 3 A schematic diagram of the structure of the atomizer core provided in one embodiment of the present application; Figure 4a for Figure 3 A cross-sectional view of the atomizer core taken along the AA direction; Figure 4b for Figure 4a Disassembly diagram of the Figure 5 for Figure 3 A cross-sectional view of the atomizer core taken along the BB direction; Figure 6 This is a schematic diagram of the structure of the atomizer core provided by one embodiment of the present application, excluding the liquid inlet pipe; Figure 7 A schematic structural diagram of the first liquid-guiding member with a five-layer structure provided in the first embodiment of the present application after unfolding; Figure 8 for Figure 7 Schematic diagram of the disassembly.

[0060] In this embodiment, if Figures 3 to 6 As shown, an atomizer core 20 is provided. The atomizer core 20 includes a first liquid guide member 21, a heating member 22, a liquid inlet pipe 23, a heating seat 24 and a second liquid guide member 25.

[0061] The liquid inlet tube 23 has a tubular structure, and at least one liquid inlet hole 231 is defined on the sidewall of the liquid inlet tube 23 for passage of the aerosol-generating substrate from the liquid storage chamber 30. In one embodiment, the sidewall of the liquid inlet tube 23 is defined with multiple liquid inlet holes 231, which may be evenly spaced along the circumference of the liquid inlet tube 23. Specifically, the liquid inlet holes 231 may extend along the axial direction of the liquid inlet tube 23.

[0062] Among them, such as Figure 4a and Figure 5 As shown, the heating seat 24 has an annular side wall 241, which is embedded in the liquid inlet pipe 23 and spaced apart from the inner side wall of the liquid inlet pipe 23 to form a ventilation channel. The heating seat 24 and the liquid inlet pipe 23 can be interference fit.

[0063] Specifically, the sidewall of the heating base 24 is provided with a flow guide hole 240 for passage of the aerosol-generating substrate from the liquid inlet 231. Specifically, the flow guide holes 240 may correspond one-to-one with the positions of the liquid inlet 231 to reduce flow resistance. Furthermore, the flow guide holes 240 may be the same size and / or shape as the liquid inlet 231 to reduce flow resistance.

[0064] The first liquid guide member 21 is specifically annularly arranged within the annular side wall 241 and encloses an atomization chamber. The first liquid guide member 21 is used to guide the aerosol-generating matrix from the side of the first liquid guide member 21 close to the annular side wall 241 to the side of the first liquid guide member 21 away from the annular side wall 241. The first liquid guide member 21 can be liquid guide cotton to guide the aerosol-generating matrix through the capillary force of the liquid guide cotton. Specifically, the liquid guide cotton can be linen to ensure the temperature resistance and environmental friendliness of the first liquid guide member 21; of course, the liquid guide cotton can also be non-woven fabric.

[0065] Specifically, such as Figure 7 and Figure 8 As shown, the first liquid guiding member 21 may include at least one liquid guiding layer; the at least one liquid guiding layer may be annularly arranged in the annular side wall 241, that is, the first liquid guiding member 21 forms a hollow column. In a specific embodiment, as shown in FIG. Figure 8 As shown, the first liquid guiding member 21 includes multiple liquid guiding layers (not shown in the figure), and a first liquid guiding hole 211 is provided on at least one of the multiple liquid guiding layers, so that the first liquid guiding member 21 can specifically guide the aerosol generating matrix from the side of the first liquid guiding member 21 close to the annular side wall 241 to the side of the first liquid guiding member 21 away from the annular side wall 241 through the first liquid guiding hole 211. The first liquid guide member 21 guides the aerosol-generating matrix through the first liquid guide holes 211, which not only reduces the flow resistance and improves the flow-guiding capacity, but also, compared to a solution that only relies on the capillary force of the liquid-guiding cotton for flow guidance, because the oil supply rate of the first liquid guide member 21 is mainly determined by the relevant performance parameters of the first liquid guide holes 211, for example, the liquid supply rate of the first liquid guide member 21 can be increased by increasing the width and / or number of the first liquid guide holes 211, or reduced by reducing the width and / or number of the first liquid guide holes 211. Therefore, the oil supply rate of the first liquid guide member 21 is less affected by the tightness of the first liquid guide member 21. At the same time, in specific embodiments, the first liquid guide holes 211 can be set with corresponding parameters such as the number or width according to the actual required flow rate, which can ensure that the atomizer core 20 can avoid the problem of low oil supply rate and insufficient oil supply, and can also avoid the problem of suction leakage due to a fast oil supply rate.

[0066] Among them, the shape of the first liquid guide hole 211 is not limited, and can be circular, elongated or elliptical, etc. Among them, the elongated shape can be runway-shaped or rectangular, etc. The angle value of the angle between the length direction of the elongated first liquid guide hole 211 and the length direction of the first liquid guide member 21 after it is unfolded (i.e., the inclination angle value α) can be 0°-180°. Preferably, the angle value of the angle between the length direction of the elongated first liquid guide hole 211 and the length direction of the first liquid guide member 21 after it is unfolded can be 0°, 45° or 90°, so as to facilitate the radial, circumferential and / or axial diffusion of the aerosol-generating matrix along the first liquid guide member 21, thereby improving the uniformity of liquid conduction.

[0067] The width of the first liquid guiding hole 211 may be 1.0 mm to 5 mm, so as to utilize the capillary force of the first liquid guiding hole 211 to guide the flow while avoiding the problem of excessively fast liquid guiding rate and leakage caused by a larger width.

[0068] The second liquid guide 25 is disposed around the annular sidewall 241 and is located between the heating base 24 and the liquid inlet pipe 23, that is, embedded in the ventilation channel. The second liquid guide 25 is used to achieve ventilation of the liquid storage chamber 30, thereby maintaining the air pressure balance inside and outside the liquid storage chamber 30, thereby ensuring that the aerosol-generating matrix can smoothly flow out of the liquid storage chamber 30. The second liquid guide 25 can also be liquid guide cotton; wherein, the material of the liquid guide cotton can be non-woven fabric, or of course, linen.

[0069] The second liquid guide member 25 is at least a partial extension of the first liquid guide member 21, that is, the second liquid guide member 25 and the first liquid guide member 21 are integrally formed, and the two are made of the same piece of non-woven fabric; or, the second liquid guide member 25 is flexibly connected to the first liquid guide member 21 to fix one end of the second liquid guide member 25 to the first liquid guide member 21, so that during the assembly of the second liquid guide member 25, it is only necessary to wrap the other end of the second liquid guide member 25 along the circumference of the annular side wall 241 of the heating seat 24 to achieve the assembly of the second liquid guide member 25, thereby significantly reducing the assembly difficulty of the second liquid guide member 25 and reducing the assembly time. The flexible connection between the second liquid guide member 25 and the first liquid guide member 21 can be suturing, gluing, snapping or clamping. In some embodiments, the first liquid guiding member 21 and / or the second liquid guiding member 25 have multiple liquid guiding layers. The flexible connection between the first liquid guiding member 21 and the second liquid guiding member 25 may refer to that one or more liquid guiding layers of the first liquid guiding member 21 are flexibly connected to one or more liquid guiding layers of the second liquid guiding member 25 respectively; the second liquid guiding member 25 is at least a partial extension of the first liquid guiding member 21, which may refer to that one or more liquid guiding layers of the second liquid guiding member 25 are extensions of one or more liquid guiding layers of the first liquid guiding member 21 respectively.

[0070] Specifically, an opening may be provided on the annular side wall 241, and the first liquid guiding member 21 and the second liquid guiding member 25 are flexibly connected at the opening. The following embodiments take this as an example. Figure 6 The first liquid guide member 21 has opposing first and second ends along its circumferential direction, and the second liquid guide member 25 has opposing third and fourth ends along its circumferential direction. The third end of the second liquid guide member 25 is flexibly connected to the first end of the first liquid guide member 21 at the opening. The portion of the second liquid guide member 25 that is distinct from the first end is disposed circumferentially around the annular sidewall 241, and the fourth end of the second liquid guide member 25 may overlap or be offset with the third end along its radial direction. In a specific embodiment, the guide holes 240 and an opening may be equally spaced around the annular sidewall 241, and the opening may also function as a guide hole 240.

[0071] The opening may be a notch extending to the top of the annular side wall of the heating seat 24, so as to facilitate the second liquid guiding member 25 to extend out of the annular side wall 241. Of course, in other embodiments, a portion of the second liquid guiding member 25 may also bypass the top or bottom of the annular side wall 241 of the heating seat 24 and be flexibly connected to the first liquid guiding member 21. This application is not limited to this, as long as one end of the second liquid guiding member 25 can be fixed by the first liquid guiding member 21.

[0072] like Figure 6 As shown, in a specific embodiment, the first liquid guiding member 21 includes multiple liquid guiding layers, at least one of which extends out of the opening and surrounds the annular side wall 241 by one or more circles, thereby forming the second liquid guiding member 25. It can be understood that when one of the multiple liquid guiding layers extends out of the opening and surrounds the annular side wall 241 by one circle, the second liquid guiding member 25 is a single-layer liquid guiding layer, that is, Figure 6 When one of the multiple liquid-conducting layers extends beyond the opening and wraps around the annular sidewall 241 multiple times, i.e., it wraps around the annular sidewall 241, the second liquid-conducting member 25 comprises multiple liquid-conducting layers. In a specific embodiment, regardless of whether the second liquid-conducting member 25 is a single-layer liquid-conducting layer or multiple-layer liquid-conducting layers, the second liquid-conducting member 25 and the liquid-conducting layer in the first liquid-conducting member 21 that are flexibly connected to each other are preferably formed from the same layer of non-woven fabric.

[0073] Specifically, such as Figure 6 As shown, a liquid-conducting layer in the multi-layer liquid-conducting layer is arranged close to the annular side wall 241, that is, a liquid-conducting layer in the multi-layer liquid-conducting layer closest to the annular side wall 241 extends out of the opening and is arranged around the annular side wall 241 one or more circles, thereby forming a second liquid-conducting member 25.

[0074] In a specific embodiment, if Figure 6As shown, at least one of the multiple liquid-guiding layers is arranged within the annular sidewall 241 along a first direction around the annular sidewall 241, then extends out of the opening and then wraps around the annular sidewall 241 one or more times in a second direction opposite to the first direction, thereby forming a second liquid-guiding member 25. The second liquid-guiding member 25 and the liquid-guiding layer of the first liquid-guiding member 21, which are flexibly connected to each other, are arranged in opposite directions within the annular sidewall 241 and outside the annular sidewall 241. This minimizes the possibility that the second liquid-guiding member 25 may rotate partially due to high forces during assembly, or that the liquid-guiding layer of the second liquid-guiding member 25 and the first liquid-guiding member 21 may be pulled out of the annular sidewall 241. The first direction can be clockwise or counterclockwise. Of course, at least one of the multiple liquid-guiding layers can wrap around the annular sidewall 241 in the same direction both within and outside the annular sidewall 241, i.e., the first liquid-guiding member 21 and the second liquid-guiding member 25 wrap around the same direction. This is not a limitation of the present application.

[0075] The heating element 22 is disposed on the side of the first liquid-guiding member 21 away from the annular sidewall 241 and is used to heat and atomize the aerosol-generating substrate when powered. Specifically, the heating element 22 is disposed on the surface of the first liquid-guiding member 21 away from the annular sidewall 241, that is, the heating element 22 is disposed on the innermost surface of the first liquid-guiding member 21, to heat and atomize the aerosol-generating substrate directed to the innermost surface of the first liquid-guiding member 21. The heating element 22 can be a heating film or a metal frame, such as a copper mesh.

[0076] The atomizer core 20 provided in this embodiment is provided with a heating seat 24 and a first liquid guide member 21, and the first liquid guide member 21 is provided in the annular side wall 241 of the heating seat 24, so that the aerosol generating substrate is guided from the side of the first liquid guide member 21 close to the annular side wall 241 to the side of the first liquid guide member 21 away from the annular side wall 241 through the first liquid guide member 21; at the same time, a first liquid guide hole 211 is provided on the first liquid guide member 21, so that the aerosol generating substrate is guided from the side of the first liquid guide member 21 close to the annular side wall 241 to the side of the first liquid guide member 21 away from the annular side wall 241 through the first liquid guide hole 211; in this way, not only the tightness of the first liquid guide member 21 is avoided from affecting the liquid guide rate of the atomizer core 20, but also the number, width and other parameters of the first liquid guide holes 211 can be controlled. It ensures that the atomizer core 20 is not only adequately supplied with oil during the atomization process, but also does not have the problem of suction leakage, thereby effectively extending the service life of the heating element 22; in addition, by arranging the second liquid guide member 25 around the outside of the annular side wall 241, and flexibly connecting the second liquid guide member 25 to the first liquid guide member 21, so that one end of the second liquid guide member 25 is fixed to the first liquid guide member 21, so that during the assembly of the second liquid guide member 25, it is only necessary to wrap the other end of the second liquid guide member 25 along the heating seat 24 to achieve the assembly of the second liquid guide member 25, thereby significantly reducing the assembly difficulty of the second liquid guide member 25 and reducing the assembly time; in addition, by arranging the heating element 22, the heating element 22 is arranged on the side of the first liquid guide member 21 away from the annular side wall 241, so as to heat and atomize the aerosol generating matrix when power is turned on.

[0077] In this embodiment, if Figure 8 As shown, the first liquid-conducting member 21 specifically comprises a stack of multiple non-porous liquid-conducting layers 21a and multiple porous liquid-conducting layers 21b. First liquid-conducting holes 211 are specifically defined in the porous liquid-conducting layers 21b; each porous liquid-conducting layer 21b may include multiple, spaced-apart first liquid-conducting holes 211 to improve the uniformity of the aerosol-generating matrix on the first liquid-conducting member 21. Specifically, the multiple first liquid-conducting holes 211 on different porous liquid-conducting layers 21b may be arranged in a one-to-one correspondence, as will be used in the following embodiments. Of course, staggered or irregularly distributed arrangements are also possible, and this is not a limitation of the present application. In this embodiment, by making the first liquid-conducting member 21 include a non-porous liquid-conducting layer 21a and a porous liquid-conducting layer 21b, not only can the first liquid-conducting holes 211 on the porous liquid-conducting layer 21b be used to conduct liquid to the aerosol-generating substrate, but the non-porous liquid-conducting layer 21a can also be used to avoid the problem of a fast oil supply rate in the first liquid-conducting holes 211 and leakage. Therefore, by adjusting the number and layout of the non-porous liquid-conducting layer 21a and the porous liquid-conducting layer 21b, the diffusion rate of the aerosol-generating substrate in the first liquid-conducting member 21 can be effectively controlled.

[0078] Figure 8In the embodiment, the first liquid-conducting member 21 has a five-layer structure, including three non-porous liquid-conducting layers 21a and two porous liquid-conducting layers 21b. The two porous liquid-conducting layers 21b are both non-woven fabrics. The three non-porous liquid-conducting layers 21a include two layers of linen and one layer of non-woven fabric. The non-woven fabric serving as the non-porous liquid-conducting layers 21a is sandwiched between the two layers of linen and the two layers of porous liquid-conducting layers 21b.

[0079] In a specific embodiment, if Figure 8 As shown, all non-porous liquid-conducting layers 21a are arranged on the same side of all porous liquid-conducting layers 21b. Figure 9 , Figure 9 This is a disassembled schematic diagram of the six-layer first liquid-conducting member provided in the second embodiment of the present application. Non-porous liquid-conducting layers 21a and porous liquid-conducting layers 21b are alternately arranged. In this specific embodiment, one, two, or three non-porous liquid-conducting layers 21a may be arranged between two adjacent porous liquid-conducting layers 21b; alternatively, one, two, or three porous liquid-conducting layers 21b may be arranged between two adjacent non-porous liquid-conducting layers 21a, although this application does not limit this. Figure 9 In the embodiment, from the outermost layer to the innermost layer, the first and third layers are porous liquid-conducting layers 21b, and the other layers are non-porous liquid-conducting layers 21a; the first, second and fourth layers are non-woven fabrics, and the other layers are linen.

[0080] In a specific embodiment, the heating element 22 is in contact with the non-porous liquid-conducting layer 21a of the first liquid-conducting element 21. That is, at least one liquid-conducting layer of the first liquid-conducting element 21 that contacts the heating element 22 is a non-porous liquid-conducting layer 21a. This increases the effective contact area between the heating element 22 and the first liquid-conducting element 21 and improves atomization uniformity. In a specific embodiment, several adjacent liquid-conducting layers disposed immediately adjacent to the heating element 22 may be non-porous liquid-conducting layers 21a to prevent excessively rapid oil supply.

[0081] Furthermore, in the first liquid guiding member 21 , except for the liquid guiding layer in contact with the heating element 22 , at least one liquid guiding layer disposed close to the heating seat 24 is a porous liquid guiding layer 21 b to reduce the oil supply resistance and increase the oil supply rate.

[0082] Among them, see Figures 10a to 10e ,in, Figure 10a A schematic structural diagram of a porous liquid-conducting layer provided in the first embodiment of the present application; Figure 10b A schematic structural diagram of a porous liquid-conducting layer provided in the second embodiment of the present application; Figure 10c A schematic structural diagram of a porous liquid-conducting layer provided in the third embodiment of the present application; Figure 10d A schematic structural diagram of a porous liquid-conducting layer provided in a fourth embodiment of the present application; Figure 10e This is a schematic structural diagram of the porous liquid-conducting layer provided in the fifth embodiment of the present application.

[0083] In one embodiment, if Figure 10a As shown, the first liquid-conducting holes 211 on the same porous liquid-conducting layer 21b have different shapes, and the first liquid-conducting holes 211 of different shapes are alternately distributed along the circumference of the porous liquid-conducting layer 21b to regulate the liquid-conducting rate of the entire first liquid-conducting member 21. Specifically, the same porous liquid-conducting layer 21b may include vertically arranged elongated first liquid-conducting holes 211 and circular first liquid-conducting holes 211, which are alternately distributed and evenly spaced to guide liquid to the aerosol-generating substrate in the axial and radial directions.

[0084] In another embodiment, Figures 10b to 10e As shown, the shapes of the multiple first liquid conducting holes 211 on the same porous liquid conducting layer 21b are the same, for example, all are in the shape of a racetrack (see Figure 10b 、 Figure 10c or Figure 10d ) or round (see Figure 10e ), and the plurality of first liquid conducting holes 211 can be arranged at equal intervals along the circumferential direction of the porous liquid conducting layer 21b.

[0085] In one embodiment, the first liquid guiding holes 211 on the same porous liquid guiding layer 21b have the same shape, while the first liquid guiding holes 211 on different porous liquid guiding layers 21b have different shapes, so as to regulate the overall liquid guiding rate and diffusion range of the first liquid guiding member 21. For example, the first liquid guiding holes 211 on one of two adjacent porous liquid guiding layers 21b are elongated, while the first liquid guiding holes 211 on the other porous liquid guiding layer 21b are circular; or, as follows Figure 11-12 As shown, the first liquid conducting holes 211 on one layer of the porous liquid conducting layer 21b are long strips with an inclination angle α of 45°, and the first liquid conducting holes 211 on the other layer of the porous liquid conducting layer 21b are long strips with an inclination angle α of 135°, so as to increase the lateral diffusion range of the aerosol generating matrix.

[0086] In another specific embodiment, the first liquid guiding holes 211 on the same porous liquid guiding layer 21b have the same shape, while the first liquid guiding holes 211 on different porous liquid guiding layers 21b have the same shape but are arranged differently. For example, the first liquid guiding holes 211 on both porous liquid guiding layers 21b may be elongated or circular, but the first liquid guiding holes 211 on one porous liquid guiding layer 21b are evenly spaced along the circumference of the porous liquid guiding layer 21b, while the first liquid guiding holes 211 on the other porous liquid guiding layer 21b are evenly distributed throughout the porous liquid guiding layer 21b.

[0087] In another specific embodiment, Figure 8As shown, the first liquid-conducting holes 211 on the same porous liquid-conducting layer 21b have the same shape, and the first liquid-conducting holes 211 on different porous liquid-conducting layers 21b have the same shape and are arranged in the same manner. Specifically, the first liquid-conducting holes 211 on two adjacent liquid-conducting layers also have the same shape and are arranged in a one-to-one correspondence to improve liquid-conducting efficiency. In this embodiment, the first liquid-conducting holes 211 may be in the shape of a racetrack extending along the width of the liquid-conducting layer.

[0088] See also Figures 11 to 16 ,in, Figure 11 A schematic structural diagram of a first liquid-conducting member with a six-layer structure provided in the third embodiment of the present application; Figure 12 for Figure 11 Disassembly diagram of the Figure 13 A disassembled schematic diagram of a first liquid-guiding component with a six-layer structure provided in the fourth embodiment of the present application; Figure 14 A schematic structural diagram of a first liquid-guiding member provided in a fifth embodiment of the present application; Figure 15 for Figure 14 Disassembly diagram of the Figure 16 This is a disassembled schematic diagram of the first liquid-conducting member of the six-layer structure provided in the sixth embodiment of the present application. The first liquid-conducting holes 211 on each porous liquid-conducting layer 21b are all in the shape of a long strip.

[0089] In a specific embodiment, if Figures 11 to 13 As shown, the projections of the first liquid-conducting holes 211 on two adjacent porous liquid-conducting layers 21b in the thickness direction of the porous liquid-conducting layers 21b intersect at an angle of 30°-90°, thereby directing liquid to the aerosol-generating substrate in different directions. Specifically, the sum of the inclination angle α of the first liquid-conducting holes 211 on one of the two adjacent porous liquid-conducting layers 21b and the inclination angle α of the first liquid-conducting holes 211 at corresponding positions on the other porous liquid-conducting layer 21b can be 180 degrees. Preferably, the corresponding first liquid-conducting holes 211 on the two adjacent porous liquid-conducting layers 21b are projected to intersect at an angle of 90°. For example, if the inclination angle α of the first liquid conducting holes 211 on one of the two adjacent porous liquid conducting layers 21b is 45°, then the inclination angle α of the first liquid conducting holes 211 at the corresponding position on the other porous liquid conducting layer 21b is 135°, so as to facilitate the diffusion of the aerosol generating matrix along the circumferential and axial directions of the first liquid conducting member 21.

[0090] In another specific embodiment, Figures 14 to 16As shown, the first liquid-conducting holes 211 on two adjacent porous liquid-conducting layers 21b are staggered, and the projections of the first liquid-conducting holes 211 on the two adjacent porous liquid-conducting layers 21b in the thickness direction of the porous liquid-conducting layers 21b are connected end to end, so that the first liquid-conducting holes 211 are connected to each other, thereby improving the liquid-conducting rate and uniformity. In this embodiment, the inclination angle α of each first liquid-conducting hole 211 is greater than 0°. Preferably, if the inclination angle α of the first liquid-conducting holes 211 on one of the two adjacent porous liquid-conducting layers 21b is 45°, the inclination angle α of the first liquid-conducting holes 211 at the corresponding position on the other porous liquid-conducting layer 21b is 135°.

[0091] Of course, in other embodiments, the shapes of the multiple first liquid-conducting holes 211 on the same porous liquid-conducting layer 21b may be partially identical, partially different, or completely different. The shapes and positions of the first liquid-conducting holes 211 on different liquid-conducting layers may also be selected based on actual needs. For example, the projections of the first liquid-conducting holes 211 in the thickness direction of the porous liquid-conducting layer 21b may partially overlap or not overlap. This application does not impose any restrictions on this, as long as sufficient liquid supply is ensured and leakage is prevented.

[0092] In a specific embodiment, Figure 4b As shown, in order to reduce the impact of the second liquid guide member 25 on the flow rate of the atomizer core 20 and ensure the liquid supply rate without affecting the ventilation of the second liquid guide member 25, a plurality of second liquid guide holes 251 can be opened in the second liquid guide member 25, so that the aerosol-generating substrate entering the liquid inlet hole 231 can be drained to the first liquid guide member 21 through the second liquid guide holes 251. Specifically, the plurality of second liquid guide holes 251 can be spaced apart along the length direction of the second liquid guide member 25 after it is deployed, and each second liquid guide hole 251 can be arranged corresponding to the flow guide hole 240 or the opening, that is, each second liquid guide hole 251 can be aligned with the flow guide hole 240 or the opening. Furthermore, each second liquid guide hole 251 can also be arranged corresponding to the liquid inlet hole 231. Among them, because one end of the second liquid guide member 25 is fixed to the notch, the distance between the second liquid guide hole 251 and the third end of the second liquid guide member 25 matches the distance between the guide hole 240 and the notch. At the same time, the hole or notch of the heating seat 24 also matches the liquid guide hole 251, so that the first liquid guide hole 211, the liquid inlet hole 231, and the second liquid guide hole 251 exactly correspond to each other, reducing the pre-manual alignment steps in the manufacturing process of the prior art and improving the consistency and efficiency of assembly. In a specific embodiment, each guide hole 240, each opening, and each liquid inlet hole 231 corresponds to at least one second liquid guide hole 251.

[0093] Specifically, the second liquid-guiding member 25 can be a liquid-guiding layer, and the second liquid-guiding member 25 can specifically be liquid-guiding cotton. In a specific embodiment, the shape and distribution of the second liquid-guiding holes 251 on the second liquid-guiding member 25, as well as the distribution of the second liquid-guiding holes 251 on different liquid-guiding layers, can be the same or similar to the shape and distribution of the first liquid-guiding holes 211 on the first liquid-guiding member 21, and can achieve the same or similar technical effects, which will not be repeated here.

[0094] It will be understood that in a specific embodiment, the aerosol-generating substrate within the liquid storage chamber 30 is sequentially directed through the liquid inlet hole 231, the second liquid guide hole 251, and the flow guide hole 240 to the side of the first liquid guide member 21 near the annular sidewall 241, and then through the first liquid guide hole 211 to the side of the first liquid guide member 21 away from the annular sidewall 241, where it is heated and atomized by the heating element 22 to form an aerosol. In a specific embodiment, the first liquid guide hole 211 and / or the second liquid guide hole 251 can be through holes.

[0095] Further, see Figure 17 and Figure 18 , Figure 17 A schematic structural diagram of a first liquid-guiding member or a second liquid-guiding member provided in an embodiment of the present application; Figure 18 This is a schematic diagram of another embodiment of the present application, showing a structure in which slits are provided in the first or second liquid-guiding member. In one embodiment, the first liquid-guiding member 21 and / or the second liquid-guiding member 25 further have multiple slits 212. This allows the aerosol-generating substrate to flow along and through the slits 212, while also reducing stress on the first liquid-guiding member 21 and / or the second liquid-guiding member 25, facilitating installation. The width of the slits 212 ranges from 0.1 mm to 2 mm.

[0096] In a specific embodiment, if Figure 17 As shown, each slit 212 may extend along the circumferential direction of the first liquid guiding member 21 or the second liquid guiding member 25 , and a plurality of slits 212 may be arranged at equal intervals along the width direction of the first liquid guiding member 21 or the second liquid guiding member 25 .

[0097] In another specific embodiment, Figure 18 As shown, the angle between the length direction of each slit 212 and the length direction of the first liquid guiding member 21 and / or the second liquid guiding member 25 after unfolding is greater than 0° and less than or equal to 90°; and multiple slits 212 can be arranged at equal intervals along the circumferential direction of the slit 212.

[0098] For details, see Figure 19 , Figure 19A structural schematic diagram of a gap provided on the first liquid guiding member or the second liquid guiding member in another embodiment of the present application; when the first liquid guiding member 21 and / or the second liquid guiding member 25 have both liquid guiding holes and gaps 212, the gaps 212 can connect adjacent liquid guiding holes, thereby further increasing the circumferential or axial liquid guiding effect of the liquid guiding member.

[0099] In a specific embodiment, the atomizer core 20 may further include a seal and an ejector pin. The seal is disposed at the bottom of the base and is used to seal the atomization chamber to prevent leakage of the aerosol-generating substrate within the atomization chamber and short circuiting of the leads of the heating element 22. Specifically, the seal may be made of sealing silicone.

[0100] The ejector pin is connected to the heating element 22, and the ejector pin is used to connect to the power supply assembly 102 to connect the heating element 22 with the power supply assembly 102, so that the power supply assembly 102 supplies power to the heating element 22. In a specific embodiment, an air inlet and two mounting holes are provided on the heating seat 24; wherein, the atomizing chamber is connected to the outside atmosphere through the air inlet to form an airflow during the user's inhalation process. The ejector pin is inserted into the mounting hole to connect with the heating element 22 in the atomizing chamber. Specifically, the ejector pin may include a positive electrode ejector pin and a negative electrode ejector pin, and the positive electrode ejector pin and the negative electrode ejector pin are arranged in a one-to-one correspondence with the two mounting holes.

[0101] See also Figure 20 , Figure 20 This is a flow chart of a method for preparing an atomizer core provided in one embodiment of the present application. In this embodiment, a method for preparing an atomizer core is provided, and the method includes:

[0102] Step S11: providing a heating seat.

[0103] The heating base 24 has an annular sidewall 241. In one embodiment, the annular sidewall 241 is provided with a guide hole 240 and an opening. The guide holes 240 may be multiple, each for allowing the aerosol-generating substrate to pass through. The guide holes 240 and the opening are spaced apart along the circumference of the annular sidewall 241. In a specific embodiment, the opening may be a notch extending from the open end of the heating base 24 toward the bottom thereof.

[0104] Step S12: providing a liquid guiding member.

[0105] The liquid guide member has a first part and a second part, wherein the second part is at least a partial extension of the first part, or the second part is flexibly connected to the first part.

[0106] In some embodiments, the first part and / or the second part has multiple liquid-conducting layers, and the flexible connection between the first part and the second part may mean that one or more liquid-conducting layers of the first part are flexibly connected to one or more liquid-conducting layers of the second part respectively; the second part is at least a partial extension of the first part, which may mean that one or more liquid-conducting layers of the second part are extensions of one or more liquid-conducting layers of the first part respectively.

[0107] In a specific embodiment, step S12 specifically includes stacking multiple liquid-conducting layers, wherein at least one liquid-conducting layer may be longer than the other liquid-conducting layers. The portion of the at least one liquid-conducting layer that is longer than the other liquid-conducting layers forms an extension, which serves as the second portion; the remaining portion of the at least one liquid-conducting layer and the other liquid-conducting layers together serve as the first portion. The following embodiment uses this as an example. Of course, in other embodiments, the multiple liquid-conducting layers may also have the same length. The liquid-conducting layers may be liquid-conducting cotton, which may be made of linen or non-woven fabric.

[0108] Specifically, multiple first liquid-conducting layers are stacked on a first portion of a second liquid-conducting layer; each first liquid-conducting layer may have the same length; the second liquid-conducting layer is longer than each first liquid-conducting layer, and a second portion of the second liquid-conducting layer extends beyond the first liquid-conducting layer. In a specific embodiment, the second portion of the second liquid-conducting layer forms an extension.

[0109] In a specific embodiment, first liquid-conducting holes 211 may be provided in the first portion of the multi-layered first liquid-conducting layer and the second liquid-conducting layer to guide the aerosol-generating substrate through the first liquid-conducting holes 211, thereby reducing the flow resistance. Specifically, the first liquid-conducting holes 211 may be spaced apart along the length of the first portion of the multi-layered first liquid-conducting layer and the second liquid-conducting layer. The first liquid-conducting holes 211 may be through holes.

[0110] It should be noted that, in the specific implementation process, the order of step S11 and step S12 is not limited.

[0111] Step S13: disposing the first portion of the liquid guiding member in the annular side wall of the heating seat to form a first liquid guiding member, and extending the second portion of the liquid guiding member out of the annular side wall.

[0112] Step S12 specifically includes: disposing the remaining portions of the multi-layer liquid-conducting layer, excluding the extension portion, within the annular sidewall 241 of the heating seat 24 to form the first liquid-conducting member 21, and allowing the extension portion to extend from the opening of the annular sidewall 241. Of course, in other embodiments, the extension portion may also extend from the annular sidewall 241 around the top or bottom end of the annular sidewall 241, and this application is not limited thereto.

[0113] In one embodiment, step S12 specifically includes: surrounding a plurality of first liquid-conducting layers and first portions of the second liquid-conducting layers within the annular sidewall 241 of the heating seat 24 to form the first liquid-conducting member 21, and allowing the second portion of the second liquid-conducting layer to extend from the opening of the annular sidewall 241. The first portion of the second liquid-conducting layer is disposed adjacent to the inner wall surface of the annular sidewall 241 so that the second portion of the second liquid-conducting layer extends beyond the annular sidewall 241.

[0114] In a specific embodiment, the first liquid conducting holes 211 on the first portion of the plurality of first liquid conducting layers and the second liquid conducting layer are aligned with the flow conducting holes 240 or openings on the annular side wall 241 to further reduce the flow resistance to the aerosol generating substrate.

[0115] Specifically, when the lengths of the multiple liquid-conducting layers are the same, after the multiple liquid-conducting layers are arranged in the annular side wall 241 of the heating seat 24, the excess parts of some liquid-conducting layers are cut off to form a first liquid-conducting part 21 located in the annular side wall 241 of the heating seat 24; then step S14 is performed on the liquid-conducting layer that has not been cut.

[0116] Step S14: disposing the second portion of the liquid guiding member around the outer wall surface of the annular side wall to form a second liquid guiding member.

[0117] Specifically, the extension portion is disposed around the outer surface of the annular sidewall 241 one or more times to form the second liquid guiding member 25. In one specific embodiment, step S14 specifically involves disposing the second portion of the second liquid guiding layer around the outer surface of the annular sidewall 241 one or more times to form the second liquid guiding member 25. The number of times the second portion of the second liquid guiding layer is disposed around the outer surface of the annular sidewall 241 can be determined based on actual needs to adjust the length of the extension portion or the second portion of the second liquid guiding member 25 to meet the required number of turns of the second liquid guiding member 25.

[0118] In a specific implementation, the second portion of the extension portion or the second liquid guiding member 25 can be wound along the circumferential direction of the annular side wall 241 in a direction opposite to the winding direction of the first liquid guiding member 21, so as to minimize the problem of the second portion of the extension portion or the second liquid guiding member 25 being pulled out of the annular side wall 241 due to the large force applied during the winding process. Of course, the second portion of the extension portion or the second liquid guiding member 25 can also be wound along the circumferential direction of the annular side wall 241 in the same direction as the winding direction of the first liquid guiding member 21, and this application is not limited to this.

[0119] In one embodiment, the preparation method may further include: forming a plurality of second liquid-conducting holes 251 in the second portion of the liquid-conducting member. This can reduce the resistance of the aerosol-generating substrate passing through the second portion of the liquid-conducting member, thereby increasing the liquid-conducting rate and avoiding the problem of insufficient liquid supply. The specific positions of the second liquid-conducting holes 251 can be pre-set based on the specifications of the atomizer 101.

[0120] Specifically, the second liquid-conducting holes 251 can be provided on the second portion of the second liquid-conducting layer. Multiple second liquid-conducting holes 251 can be provided, spaced apart along the length of the second portion of the second liquid-conducting layer after it is unfolded. After being wound around the outer wall of the annular sidewall 241, each second liquid-conducting hole 251 is positioned corresponding to the flow-conducting hole 240 or opening, thereby further reducing the resistance of the aerosol-generating substrate passing through the second portion of the liquid-conducting member.

[0121] In the specific implementation process, this step can be performed before step S13 or step S14. The present application does not limit the order of the steps, as long as the second liquid guide hole 251 is opened on the second part of the liquid guide member.

[0122] The method for preparing the atomizer core provided in this embodiment comprises providing a heating seat 24 and a liquid guide member; then disposing the first portion of the liquid guide member within the annular side wall 241 of the heating seat 24 to form the first liquid guide member 21, and allowing the second portion of the liquid guide member to extend out of the annular side wall 241; thereafter, disposing the second portion of the liquid guide member around the outer wall surface of the annular side wall 241 to form the second liquid guide member 25; wherein, since the portion forming the second liquid guide member 25 is flexibly connected to the first liquid guide member 21, in the process of forming the second liquid guide member 25, it is only necessary to wrap the end of the second portion of the liquid guide member away from the first portion of the liquid guide member along the outer wall surface of the annular side wall 241 to form the second liquid guide member 25. Compared with the prior art, in which the first liquid guide member 21 and the second liquid guide member 25 are independently provided, and then one end of the second liquid guide member 25 is pressed by a finger and then the second liquid guide member 25 is wrapped around the outer wall surface of the annular side wall 241 with another finger, the difficulty of assembling the second liquid guide member 25 is significantly reduced, and the assembly time is reduced.

[0123] The above is only an implementation method of the present application and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the description and drawings of this application, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
