In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0062] In a first aspect, the present application provides a heating element 10, the heating element 10 comprising a heat conducting member 11 and a heating member 12, see Figure 1-Figure 8 .

[0063] The heat conducting member 11 and the heating member 12 are an integrated structure, wherein the number of the heat conducting members 11 is two and they are arranged at intervals along the first direction X, and the heating member 12 is located in the middle of the two heat conducting members 11 and is connected to the two heat conducting members 11. When in use, the two heat conducting members 11 are used to connect with the electrode 40 to realize power supply, and the heating member 12 can generate heat in the power supply state, and part of the heat generated directly acts on the liquid conducting member 20 in contact and fit with it, and part of the heat is transferred to the heat conducting member 11. The heat conducting member 11 receives the heat transferred from the heating member 12, and acts on the liquid conducting member 20 in contact and fit with it.

[0064] Since the heating element 10 can achieve electrical connection with the electrode 40 without additional welding pins, the quality problem caused by poor pin welding processing can be effectively overcome, and the processing steps of the heating element 10 can be simplified, the processing cost can be reduced, and the processing yield of the heating element 10 can be improved to a certain extent. In addition, since the heating element 12 and the heat-conducting element 11 can directly contact the liquid-conducting component 20, the heating element 10 can directly act on the liquid-conducting component 20 adsorbed with a proper amount of aerosol-forming matrix during operation, so the heat transfer path can be effectively shortened, and the effect of quickly transferring heat to the aerosol-forming matrix can be achieved, which helps to increase the aerosol formation rate and reduce the heat loss of the heating element 10.

[0065] Specifically, at least part of the heat generating element 12 and at least part of the heat conducting element 11 are suitable for contacting the liquid conducting component 20 .

[0066] The above-mentioned liquid-conducting component 20 needs to contact the heating element 12 as much as possible and fit with the surface of the heating element 12 to increase the rate of aerosol formation. With respect to the heat-conducting component 11, in order to improve the connection firmness between the heating element 12 and the liquid-conducting component 20 and avoid the separation of the liquid-conducting component 20 and the heating element 12, it is generally necessary to set part of the liquid-conducting component 20 to contact and fit with the heat-conducting component 11; in addition, since the heat-conducting component 11 can receive part of the heat transferred from the heating element 12, the part of the liquid-conducting component 20 in contact with the heat-conducting component 11 can also absorb the heat from the heat-conducting component 11 to achieve preliminary heating, which can make the liquid-conducting component 20 more evenly heated, improve the problem of local overheating of the aerosol-forming matrix in the liquid-conducting component 20 or excessive temperature difference of the aerosol-forming matrix at different positions of the liquid-conducting component 20, and help to produce a more delicate and uniform aerosol, and enhance the user experience. After the aerosol-forming substrate that has undergone preliminary heating treatment moves within the liquid-conducting component 20 to the area opposite to the heating element 12, its atomization rate for forming an aerosol can be increased to optimize the user's experience.

[0067] During actual processing, the size of the liquid-conducting component 20 or the size of the heat-conducting component 11 can be adjusted to ensure that at least a portion of the heat-conducting component 11 can fit the surface of the liquid-conducting component 20 .

[0068] It should be noted that the heat conducting element 11 and the heating element 12 are an integrated structure and need to be distinguished based on the cross-sectional area: the cross-sectional area of ​​the heating element 12 is smaller than the cross-sectional area of ​​any heat conducting element 11 .

[0069] Since the heating element 12 and the heat-conducting element 11 are made of the same conductive material, under the same other conditions, the smaller the cross-sectional area, the greater the resistance. Therefore, when the heating element 10 is powered on, the heating element 12 with a smaller cross-sectional area can generate more heat and heat up faster due to its larger resistance; the heat-conducting element 11 with a smaller cross-sectional area can receive part of the heat transferred from the heating element 12 due to its smaller heat generation and slower heating rate.

[0070] In some embodiments, the cross-sectional area of ​​the heating element 12 can be set to 10%-55% of the cross-sectional area of ​​the heat conducting element 11. For example, the cross-sectional area of ​​the heating element 12 is set to 13% of the cross-sectional area of ​​the heat conducting element 11. The specific ratio of the two can be adaptively adjusted within the range according to design requirements, such as 10%, 20%, 30%, 40%, 50%, 55%.

[0071] In other embodiments, the dimensions of the heat-conducting member 11 and the heating member 12 in the extension direction can also be adjusted according to the heating needs. The length between the two ends of the heating member 12 used to connect the two heat-conducting members 11 is defined as the extension direction length, and the length between the two ends of the heat-conducting member 11 used to connect the heating member 12 and the electrode 40 is defined as the extension direction length. For example, the length between the two ends of the heat-conducting member 11 used to connect the heating member 12 can be set to be consistent or substantially consistent with the length of any one of the heating members 12; when it is necessary to further improve the heating efficiency of the heating member 12, the length of the heating member 12 in the extension direction can be adjusted to be greater than the length of the heat-conducting member 11 in the extension direction; when it is necessary to reduce the heating efficiency of the heating member 12, the length of the heating member 12 in the extension direction can be adjusted to be less than the length of the heat-conducting member 11 in the extension direction.

[0072] Specifically, the extension length of the heating element 12 can be set to 40%-160% of the extension length of the heat conducting element 11. For example, the extension length of the heating element 12 is set to 54% of the extension length of the heat conducting element 11. The specific ratio of the two can be adaptively adjusted within the range according to design requirements, such as 40%, 50%, 60%, 70%, 80%, 90%, 100%, 110%, 120%, 130%, 140%, 150%, 160%.

[0073] Of course, in other embodiments, the heat conducting member 11 and the heating member 12 may be made of different metal materials. In this case, the conductivity of the metal material used to prepare the heating member 12 may be adjusted to be smaller than the conductivity of the metal material used to prepare the heat conducting member 11. The two different metal materials may be fixedly connected by welding or high-temperature pressing, and the above connection methods have been disclosed in the relevant art and will not be described in detail here.

[0074] The heat conducting element 11 and the heat generating element 12 are both plate-shaped structures with a certain thickness, wherein the cross-sectional area of ​​the heat generating element 12 is smaller than the cross-sectional area of ​​the heat conducting element 11 .

[0075] In some embodiments, those skilled in the art should be aware that the heating element 12 can be connected to one end of the heat-conducting element 11 in the first direction X to achieve a fixed connection between the heating element 12 and the heat-conducting element 11. In this case, the heating element 12 can be connected to two heat-conducting elements 11 through its two ends in the first direction X; of course, the heating element 12 can also be connected to one end of the heat-conducting element 11 on the circumferential side in the first direction X to achieve a fixed connection. In this case, the heating element 12 can be connected to two heat-conducting elements 11 through its two ends on the circumferential side.

[0076] For the convenience of explanation, the following description is made by taking an example in which two ends of the heat conducting element 11 in the first direction X are respectively connected to one ends of the two heating elements 12 in the first direction X.

[0077] In some embodiments, in order to improve the heating efficiency of the heating element 12, the heating element 12 is provided to include a plurality of heating strips 121 arranged at intervals, and the heating strips 121 are sequentially arranged in a certain order on a side of the heat-conducting element 11 for connecting with the heating element 12. When the heating element 12 contacts the heat-conducting element 11 along the first direction X, the heating strips 121 are sequentially arranged on one side of the heat-conducting element 11 in the first direction X.

[0078] In some embodiments, at least a portion of the heating strip 121 is a linear structure extending along the first direction X. The heating element may be arranged as a linear structure as a whole, or a portion of the heating strip 121 may be arranged as a non-linear structure. When a portion of the heating strip 121 is a non-linear structure, the non-linear structure includes one of an oblique structure and a curved structure, wherein the extending direction of the oblique structure is at an angle to the first direction X, and the curved structure includes an arc and other types of smooth curves.

[0079] It is understandable that the two ends of the heating strip 121 in the first direction X are connected to the two heating elements 12 respectively, but the heating strip 121 is not required to be arranged to extend along the first direction X, and its specific extension direction and shape can be set as needed. For example, one end of the heating strip 121 can be connected to a certain heat-conducting element 11 through a linear structure, and the other end can form an arc structure (or an oblique structure at a certain angle to the first direction X) and connected to another heat-conducting element 11, and it is only necessary to ensure that the heating strip 121 can contact the liquid-conducting component 20 at the corresponding position.

[0080] In some embodiments, the heating element 10 includes a heat-conducting member 11 in a plate-like structure and a heating member 12 composed of a plurality of heating strips 121, see Figure 1 At this time, the heating element 12 includes 5 heating strips 121 extending along the first direction X, the length and cross-sectional area of ​​each heating strip 121 are consistent, and there is a gap between any two adjacent heating strips 121.

[0081] When the heating element 10 is matched with the liquid guide component 20, the liquid guide component 20 can be arranged above the heating element 10 and in contact with the upper surface of the heating element 10; or, the liquid guide component 20 can be arranged below the heating element 10 and in contact with the lower surface of the heating element 10. Considering the use effect, the former is generally selected.

[0082] In other embodiments, at least one heat-conducting member 11 may include a bottom wall 111 and a side wall 112 , and the heat-generating member 12 may be connected to the heat-conducting member 11 via one of the bottom wall 111 and the side wall 112 .

[0083] The above bottom wall 111 and side wall 112 both extend along the first direction X. When connecting the heat conducting member 11, the heating member 12 can be connected to the bottom wall 111 of the heat conducting member 11, or to the side wall 112 of the heat conducting member 11, or can be connected to both the bottom wall 111 and the side wall 112 of the heat conducting member 11 simultaneously.

[0084] It should be noted that the above bottom wall 111 and side wall 112 extending along the first direction X do not mean that the planes of the bottom wall 111 and the side wall 112 are both parallel to the straight line where the first direction X is located. There may be a certain angle between the two.

[0085] In some embodiments, it is possible to set that a certain heat conducting member 11 in the heating element 10 has the above bottom wall 111 and side wall 112, or it is also possible to set that two heat conducting members 11 in the heating element 10 both have the above bottom wall 111 and side wall 112.

[0086] Please refer to Figure 2 , at this time, both of the above two heat conducting members 11 have the above bottom wall 111 and side wall 112, and the heating member 12 is connected to the side wall 112 of the heat conducting member 11.

[0087] Specifically, the angle between the above bottom wall 111 and side wall 112 can be an acute angle, an obtuse angle or a right angle, as long as it is ensured that the heating element 10 formed by the bottom wall 111 and the side wall 112 can cooperate with the liquid guiding member 20 and the liquid guiding member 20 can be attached to the heating member 12.

[0088] In order to further improve the connection firmness between the heating element 10 and the liquid guiding member 20 and ensure that the heating member 12 can always be attached to the liquid guiding member 20, in some embodiments, it is also possible to set that at least one heat conducting member 11 includes two side walls 112, and the two side walls 112 are respectively connected to the two circumferential ends of the heat conducting member 11 in the first direction X. The structure formed by enclosing the above bottom wall 111 and the two side walls 112 is a structure with an open top, and its structure is similar to a "U" shape or a "匚" shape rotated 90 degrees counterclockwise, and can cooperate with the liquid guiding member 20. The liquid guiding member 20 can be firmly arranged in this structure and be attached to the two side walls 112.

[0089] In some embodiments, it is possible to set that a certain heat conducting member 11 in the heating element 10 has two side walls 112, or it is also possible to set that two heat conducting members 11 in the heating element 10 both have two side walls 112.

[0090] When both of the above two heat conducting members 11 have two side walls 112, the number of heating members 12 is two and they are connected in parallel through the heat conducting members 11. The two heating members 12 are arranged oppositely, and the liquid guiding member 20 is located between the two heating members 12. In the energized state, the two heating members 12 work simultaneously and heat the liquid guiding member 20.

[0091] In order to further improve the connection firmness between the heating element 10 and the liquid guiding component 20 and ensure that the heating element 12 can always be in contact with the liquid guiding component 20, in some embodiments, at least one heat conducting member 11 may further include a top wall 113, and the side wall 112 is used to connect the bottom wall 111 and the top wall 113.

[0092] Similarly, the top wall 113 also extends along the first direction X. The structure formed by enclosing the top wall 113, the bottom wall 111 and the side wall 112 is similar to a "匚" shape in the cross-section in the first direction X. Please refer to Figure 3 . The space between the top wall 113 and the bottom wall 111 can be used to place the liquid guiding component 20. When connecting the heat conducting member 11, the heating element 12 can be connected to at least one of the top wall 113, the bottom wall 111 and the side wall 112 of the heat conducting member 11.

[0093] In some embodiments, one of the heat conducting members 11 in the heating element 10 may have the above-mentioned top wall 113, bottom wall 111 and side wall 112, or both of the two heat conducting members 11 in the heating element 10 may have the above-mentioned top wall 113, bottom wall 111 and side wall 112.

[0094] Since the liquid guiding component 20 cooperating with the heating element 10 needs to contact and adsorb the aerosol forming matrix, in order not to affect the adsorption of the aerosol forming matrix by the liquid guiding component 20, a part of the structure of the liquid guiding component 20 may be set to protrude relative to the heating element 10 to overcome the shielding and blocking of the top wall 113 on the liquid guiding component 20. Of course, a through connection structure may also be provided on the top wall 113, and the liquid guiding component 20 can adsorb the aerosol forming matrix located outside through the through connection structure.

[0095] The above-mentioned through connection structure can be used to realize the through connection of the upper and lower spaces of the top wall 113, so as to facilitate the passage of gas or liquid. In this embodiment, the above-mentioned through connection structure is used for the passage of the aerosol forming matrix.

[0096] Specifically, the above-mentioned through connection structure can be set in the center of the top wall 113, or can be set at a position deviating from the center on the top wall 113; the through connection structure can be in the shape of a hole, such as a circular hole, a square hole, an oval hole, a strip hole, a triangular hole, a semi-circular hole and an irregular hole, etc. The specific setting position and shape of the through connection structure can be adaptively adjusted according to actual needs.

[0097] Please refer to Figure 3 , the above-mentioned through connection structure is a through notch 1131 provided at one end of the top wall 113 facing away from the heating element 12. The side edge where the through notch 1131 is connected to the side wall 112 and the top wall 113 can be a linear structure, a curved structure, etc.

[0098] When a heating element 10 has the top wall 113, the bottom wall 111 and the side wall 112, and the number of the side wall 112 is two, please refer to Figure 4-Figure 6 The heating element 12 is connected to the side wall 112 of the heat conducting element 11 , and the top wall 113 is provided with a through notch 1131 .

[0099] See also Figure 5-6 The through notch 1131 is located at one end of the top wall 113 facing away from the heating element 12, and the edge of the through notch 1131 that contacts the side wall 112 and the top wall 113 is a linear structure. In a top view, the through notch 1131 is a rectangular notch.

[0100] Of course, the side of the through notch 1131 that contacts the top wall 113 may also be set to be semicircular, and in this case, the through notch 1131 may present a semicircular structure.

[0101] The heat-conducting member 11 having a top wall 113, a bottom wall 111 and two side walls 112 forms a receiving cavity 1101 for placing the liquid-conducting member 20. The liquid-conducting member 20 can contact the heat-conducting member 11 and the heat-generating member 12 through the receiving cavity 1101.

[0102] See also Figure 4 The two heat-conducting parts 11 are each formed with a receiving cavity 1101 for placing the liquid-conducting component 20. The receiving cavity 1101 is formed by connecting and enclosing a top wall 113, a bottom wall 111 and two side walls 112 in sequence. When the liquid-conducting component 20 is matched with the heating element 10 through the receiving cavity 1101, please refer to Figure 8 At this time, both ends of the liquid guiding component 20 in the first direction X are exposed relative to the through notch 1131 .

[0103] In one embodiment, the outer contour of the projection of the heat-conducting member 11 in the heating element 10 in the first direction X is a rectangle or a rounded rectangle. Figure 7 .

[0104] Of course, when the shape of any one of the top wall 113 , the bottom wall 111 and the side wall 112 changes, the above-mentioned projection shape will also change accordingly, which will not be described in detail here.

[0105] It can be understood that the heating element 10 provided in the embodiment of the present application does not require additional welding pins, which can avoid the yield problem of the heating element 10 caused by welding pins. It can not only simplify the processing steps of the heating element 10 and reduce the processing cost, but also improve the processing yield of the heating element 10 and improve its use effect; at the same time, by adjusting its structure, it can better cooperate with the liquid-conducting component 20 that adsorbs an appropriate amount of aerosol to form a matrix, which helps to increase the atomization rate of the aerosol, produce a more delicate and uniform aerosol, and optimize the user experience.

[0106] In a second aspect, the present application provides an atomizer core 100, including a heating element 10 and a liquid guide component 20, wherein the heating element 10 is in contact with the liquid guide component 20. Figure 8-Figure 14 .

[0107] In the atomizer core 100, the heating element 10 is the heating element 10 described in the above embodiment, and its specific structure can be the same as the structure in any embodiment of the above heating element 10, which will not be repeated here. The liquid guide component 20 is adsorbed with an aerosol-forming matrix and is used to contact both the heating element 12 and the heat-conducting element 11 in the heating element 10.

[0108] The liquid guide component 20 absorbs an appropriate amount of aerosol-forming substrate to transport or convey the aerosol-forming substrate within the liquid guide component 20. The heating element 10 heats the aerosol-forming substrate to generate aerosol, and the liquid guide component 20 is used to replenish the consumed aerosol-forming substrate to the heating element 10.

[0109] The specific structure of the heating element 10 can be the same as the component structure in the above embodiment. For example, the heating element 10 is a hollow structure, and the liquid guide component 20 is disposed in the hollow structure of the heating element 10 and is attached to the inner surface of the hollow structure.

[0110] The liquid-conducting component 20 is made of a porous material and may have a capillary structure or other existing structures in the related art, and is mainly used to realize the transportation of aerosol-forming substrates.

[0111] Specifically, the liquid-conducting component 20 can be made of any one or more materials such as organic cotton, glass fiber, and ceramic fiber, and has good aerosol-forming matrix adsorption and transportation performance, and can continuously adsorb the aerosol-forming matrix and continuously transport it to the heating element 10, thereby ensuring a continuous and stable supply of the aerosol-forming matrix to the heating element 10.

[0112] Depending on the material, the transport of the aerosol-forming substrate within the portion of the liquid-conducting component 20 may be directional or non-directional.

[0113] The liquid-conducting component 20 has a limited storage capacity for the aerosol-forming matrix, and the storage capacity of the aerosol-forming matrix therein depends on the adsorption rate of the aerosol-forming matrix by the liquid-conducting component 20 and the release rate of the aerosol at the heating element 12. When the two can reach a dynamic balance, the liquid-conducting component 20 can continue to work stably and without core sticking. When the aerosol release rate is greater than the adsorption rate, due to the insufficient supply of the aerosol-forming matrix and the limited storage capacity of the liquid-conducting component 20, once the content of the aerosol-forming matrix in the liquid-conducting component 20 is reduced to a certain extent, dry burning is likely to occur, thereby causing core sticking.

[0114] By making the heating element 10 and the liquid-conducting component 20 directly contact each other, the atomizing core 100 can form an aerosol at the heating element 12 while heating a portion of the liquid-conducting component 20 in contact therewith through the heat-conducting component 11, so as to accelerate the movement rate of the aerosol-forming matrix in the liquid-conducting component 20, and to a certain extent improve the adsorption rate of the aerosol-forming matrix by the liquid-conducting component 20. Therefore, the problem of insufficient liquid supply in the area where the liquid-conducting component 20 and the heating element 12 are opposite can be alleviated, and the possibility of dry burning in this area due to insufficient liquid supply can be reduced, which helps to avoid the risk of core sticking.

[0115] See also Figure 8 , a receiving cavity 1101 is provided in the heating element 10, and the liquid-conducting component 20 is located in the receiving cavity 1101. In the state of power-on heating, part of the heat emitted by the heating element 12 is transferred to the heat-conducting component 11 and preliminarily heats the part of the liquid-conducting component 20 located in the receiving cavity 1101, so as to increase the moving speed of the aerosol-forming matrix located in the receiving cavity 1101 and the surrounding part of the liquid-conducting component 20, so that the aerosol-forming matrix can flow to the position opposite to the heating element 12 faster (i.e., increase the speed at which the aerosol-forming matrix located at both ends of the liquid-conducting component 20 flows to the middle part of the liquid-conducting component 20), which helps to reduce the risk of core sticking and optimize the user experience.

[0116] See also Figure 9-12 The atomizer core 100 further includes a mounting shell 30 , in which the heating element 10 and the liquid guiding component 20 are both located.

[0117] Specifically, a through hole 301 extending along the second direction Y is provided in the middle of the mounting shell 30, a part of the structure of the heating element 10 in the mounting shell 30 is located in the through hole 301, and a distance d exists between the peripheral side of the heating element 10 in the first direction X and the inner surface of the through hole 301. It should be noted that the second direction Y is orthogonal to the first direction X.

[0118] The through holes 301 are used to guide airflow to pass through, and the aerosol generated by the heating element 10 heating the aerosol-forming matrix can flow out driven by the airflow.

[0119] At this time, a portion of the outer surface of the heating element 10 located in the through hole 301 can match with the inner surface of the through hole 301 to form a guide channel for air flow to pass through.

[0120] See also Fig.11 , the arrows in the figure are used to indicate the direction of the airflow flowing through the through holes 301. Fig.11Taking the orientation shown as an example, in the process of the airflow flowing from bottom to top along the second direction Y, the airflow below the heating element 10 will be blocked by the heating element 10 and separated into two independent airflows and flow along the guide channels formed on both sides of the heating element 10. In this process, the two airflows maintain their respective flow characteristics. With the change of the flow path, the two airflows separated by the heating element 10 approach again after flowing through the heating element 10 and merge above the heating element 10, forming a unified airflow and flowing out relative to the mounting shell 30 through the partial through-hole 301 located above the heating element 10.

[0121] When the two airflows converge above the heating element 10 , the aerosol formed on the heating element 10 can be driven to flow out quickly, which helps to improve the efficiency of aerosol formation.

[0122] When the heating element 10 is as Figure 4 In the structure shown, the heating element 10 has two heating elements 12 arranged side by side in the second direction Y. The two heating elements 12 cooperate with the two heat-conducting elements 11 to form a through hole structure, and part of the liquid-conducting component 20 is located between the two heating elements 12 .

[0123] The projections of the two heating elements 12 in the second direction Y are arranged at intervals. In addition, the heating elements 12 are all arranged corresponding to the guide channels, and the airflow flowing through the guide channels can drive the aerosol formed on the heating element 12 and its periphery to flow along the flow direction of the airflow.

[0124] The mounting shell 30 may be an integrated structure or a split structure.

[0125] In some embodiments, the mounting shell 30 includes a first sealing cover 31 and a second sealing cover 32 sequentially arranged along the second direction Y. The first sealing cover 31 and the second sealing cover 32 can be fixedly connected by bonding, snapping, or the like.

[0126] See also Figure 11-13 The first sealing cover 31 and the second sealing cover 32 are both formed with partial through holes 301 , and when the two are connected, a complete through hole 301 can be formed.

[0127] In some embodiments, the heating element 10 is located at the connection position between the first sealing cover 31 and the second sealing cover 32 .

[0128] Specifically, a mounting groove 321 and a mounting through hole 322 are provided on a side of the second sealing cover 32 facing the first sealing cover 31 , wherein the mounting groove 321 is communicated with the through hole 301 for the heating element 10 to be installed.

[0129] The structure of the second sealing cover 32 is shown in FIG. Fig.13 and Fig.14 There are two mounting grooves 321 and they are symmetrically arranged relative to the through hole 301 along the first direction X. When the heating element 10 is arranged on the second sealing cover 32 via the mounting grooves 321 , the heating element 12 in the heating element 10 is exactly located on the straight line where the through hole 301 is located.

[0130] Considering that the heating element 12 in the heating component 10 needs to be connected to the electrode 40 to achieve power supply, in some embodiments, the second sealing cover 32 is further provided with a mounting through hole 322, which is a through hole that can connect the second sealing cover 32 on both sides in the second direction Y.

[0131] Specifically, one end of the mounting through hole 322 in the second direction Y is located at the mounting groove 321, and the other end is located at the side of the second sealing cover 32 facing away from the first sealing cover 31. The electrode 40 passes through the mounting through hole 322 and points to the mounting groove 321, so as to be electrically connected to the heat conducting member 11 located at the mounting groove 321.

[0132] See also Fig.12 The above-mentioned heat-conducting member 11 is located in the mounting groove 321 and covers the mounting through-hole 322 located below the mounting groove 321. The upper end of the electrode 40 disposed in the mounting through-hole 322 can contact the lower surface of the bottom wall 111 of the heat-conducting member 11. Since the electrode 40 directly contacts the heat-conducting member 11, the contact area between the electrode 40 and the heating element 10 can be increased, and the stability of the combination of the two can be improved, which has the advantages of reducing energy loss and improving equipment reliability. At the same time, since there is no need for a pin to connect the electrode 40 and the heating element 10, the through-hole disposed on the second sealing shell and used for the pin to pass through can also be eliminated, thereby avoiding the risk of leakage of the aerosol-forming matrix through the above-mentioned through-hole, and at the same time, the assembly process can be reduced, and the assembly cost can be reduced.

[0133] When powered on, the electrode 40 is electrically connected to the heat-conducting element 11 , and the heating element 12 can convert electrical energy into thermal energy and heat the liquid-conducting component 20 .

[0134] Specifically, the mounting through hole 322 is extended along the second direction Y.

[0135] The number of the electrodes 40 should be at least two. When the number of the electrodes 40 is greater, the number of the mounting through holes 322 arranged opposite to at least one heat conducting member 11 can be adaptively adjusted as needed to meet the arrangement requirements of the electrodes 40. The structure of the electrode 40 has been disclosed in the relevant art and will not be described in detail here.

[0136] In the power-on state, the heating element 10 starts and heats the liquid-conducting component 20. In this process, as the aerosol is generated, the aerosol-forming matrix flows into the liquid-conducting component 20 through the through-hole 1131 provided on the top wall 113 of the heat-conducting member 11, thereby replenishing the aerosol-forming matrix in the liquid-conducting component 20. Fig.12 , the arrows in the figure are used to indicate the flow direction of the aerosol forming matrix. Fig.12 Taking the position shown as an example, the aerosol-forming substrate stored above the mounting shell 30 can flow into the mounting shell 30 through the liquid supply channel S provided on the first sealing cover 31 and be adsorbed by the liquid guide component 20. As the aerosol is continuously generated, the aerosol-forming substrate located in the area opposite to the liquid guide component 20 and the heat-conducting component 11 flows toward the heating element 12 in the middle of the heating element 10, thereby avoiding the risk of the core being burnt due to insufficient liquid supply of the aerosol-forming substrate in the middle of the liquid guide component 20.

[0137] In some embodiments, the first sealing cover 31 and the second sealing cover 32 are both made of silicone material.

[0138] In order to prevent aerosol-forming matrix from flowing into the liquid-conducting component 20 of the atomizing core 100 in large quantities and causing leakage, in some embodiments, a liquid storage component 50 may be provided between the first sealing cover 31 and the heating element 10, and the liquid storage component 50 is used to adsorb the aerosol-forming matrix.

[0139] Specifically, the liquid storage member 50 may be liquid storage cotton, which may be made of non-woven fabric or organic cotton, etc. The liquid storage cotton is used to absorb the aerosol-forming matrix to achieve storage of the aerosol-forming matrix.

[0140] The liquid storage cotton and the liquid guide component 20 can be directly attached to each other, or separated by a partial structure. Figure 4 and Fig.12 As shown, the top wall 113 of the heat-conducting member 11 in the heating element 10 can be used to separate the liquid storage cotton and the liquid guide component 20, and the through-notch 1131 provided on the top wall 113 is used to control the contact area and contact position between the liquid storage cotton and the liquid guide component 20. By adjusting the arrangement position and size of the through-notch 1131, it is possible to avoid a large amount of aerosol-forming substrate entering the liquid guide component 20 of the atomizing core 100 and causing leakage of the aerosol-forming substrate.

[0141] The arrangement position and shape of the liquid storage member 50 can be found in Figure 12-13 In order to prevent the liquid storage member 50 from affecting the generation and escape of aerosol, it is necessary to set the projection of the liquid storage member 50 in the second direction Y and the projection of the through hole 301 provided on the first sealing shell in the second direction Y not to completely overlap, so as to prevent the liquid storage member 50 from blocking the through hole 301.

[0142] Furthermore, the projection of the liquid storage element 50 in the second direction Y should not overlap with the through hole 301 provided on the first sealing shell, and the heating element 12 can be exposed relative to the through hole 301.

[0143] Specifically, it is also possible to set a gap between the projection of the liquid storage element 50 in the second direction Y and the projection of the heating element 12 in the second direction Y, that is, the projections of the two in the second direction Y are staggered.

[0144] It should be noted that the projection of the above-mentioned liquid storage component 50 in the second direction Y at least partially overlaps with the projection of the heat conductive component 11 in the second direction Y, and the projection of the through notch 1131 provided on the heat conductive component 11 in the second direction Y at least partially overlaps with the projection of the liquid storage component 50 in the second direction Y.

[0145] See also Fig.13 The liquid storage member 50 is a hollow ring structure. It should be noted that the liquid storage member 50 can be a circular ring, an elliptical ring or a ring structure of other shapes.

[0146] See also Figure 9-13 In some embodiments, the atomizer core 100 further includes a base 60, which is disposed on a side of the second sealed shell facing away from the first sealed shell, and a corresponding through hole is also provided in an area of ​​the base 60 opposite to the through hole 301 and the installation through hole 322 to facilitate airflow and normal installation of the electrode 40.

[0147] It can be understood that the atomizer core 100 provided in this embodiment can improve the movement rate of the aerosol-forming matrix in the liquid-conducting component 20 to reduce the risk of core sticking; in addition, since the pin structure is removed, the atomizer core 100 avoids the leakage problem of the aerosol-forming matrix caused by the pins while reducing the assembly process and reducing the assembly cost. By adjusting the structure, the electrode 40 is directly in contact with the heat conductor 11, the contact area of ​​the electrode 40 is increased, the power supply stability of the heating element is improved, and the use effect of the atomizer core 100 is effectively improved.

[0148] In a third aspect, the present application provides an atomization device 1000, see Figure 15-16 .

[0149] The atomization device 1000 includes an atomization core 100, a liquid storage tank 200 and a power supply module 300. The atomization core 100 is the atomization core 100 described above. The liquid storage tank 200 is used to store an aerosol-forming matrix. The liquid storage tank 200 is connected to a liquid guide component 20 through a liquid supply channel S. The aerosol-forming matrix in the liquid storage tank 200 enters the liquid guide component 20 through the liquid supply channel S. The power supply module 300 is electrically connected to the atomization core 100 and is used to supply power to the heating element 10 of the atomization core 100.

[0150] The liquid storage tank 200 in the atomization device 1000 is used to store the aerosol-forming matrix. The atomization core 100 is connected to the liquid storage tank 200 via a liquid supply channel S. The liquid supply channel S allows the aerosol-forming matrix in the liquid storage tank 200 to enter the liquid guide component 20 of the atomization core 100 .

[0151] See also Fig.16 The liquid storage tank 200 may be a hollow shell-like structure with one end open, in which the aerosol-forming matrix is ​​stored, and the open end may be fixedly connected to the atomizer core 100 to achieve sealing of the liquid storage tank 200. The liquid storage tank 200 may be connected to the liquid storage tank 200 through the mounting shell 30, and the first sealing cover 31 is disposed toward one side of the liquid storage tank 200. A liquid supply channel S is formed on the first sealing cover 31, and the aerosol-forming matrix in the liquid storage tank 200 flows into the liquid guide component 20 located in the mounting shell 30 through the liquid supply channel S disposed on the first sealing cover 31.

[0152] In some embodiments, the aerosol-forming matrix can be directly contained in the cavity formed by the liquid storage tank 200, or a liquid-absorbing component can be arranged in the liquid storage tank 200. The liquid-absorbing component can be, for example, liquid-absorbing cotton. The aerosol-forming matrix is ​​adsorbed in the liquid-absorbing component, which can better prevent the leakage of the aerosol-forming matrix.

[0153] In other embodiments, the atomizing device 1000 may be provided with a housing 400, and the liquid storage tank 200 may be provided in the housing 400 and constituted by a part of the cavity in the housing 400. In this case, the atomizing core 100 and the liquid storage tank 200 in the atomizing device 1000 may be integrally assembled with the power supply module 300 on the housing 400. Alternatively, the atomizing core 100 and the liquid storage tank 200 in the atomizing device 1000 may be independently provided with respect to the housing 400 and detachably connected with the housing 400. In this case, the atomizing core 100 and the liquid storage tank 200 may be an integrated structure and may be separated with respect to the power supply module 300. The central part of the liquid storage tank 200 is provided with a suction channel 201 connected with the through hole 301.

[0154] The electrode 40 is used to connect the power supply module 300 and the heating element 10 in the atomizer core 100 .

[0155] In some embodiments, the power supply module 300 includes an electrically connected battery 310 and a charging interface 320. The atomization device 1000 also includes a control circuit.

[0156] Those skilled in the art should be aware that the assembly structure and appearance of each component in the atomization device 1000 can refer to the existing structures in the relevant technology, and will not be described in detail in this application.

[0157] When the atomizer 1000 is working, the power supply module 300 transmits a certain power of electric energy to the heating element 10 of the atomizer core 100 under the control of the control circuit. The heating element 10 generates heat to heat the aerosol-forming matrix adsorbed in the liquid-conducting component 20 to generate aerosol. The user inhales through the suction channel 201 formed in the middle of the liquid storage tank 200, so that the aerosol is discharged from the atomizer 1000 from the suction channel 201.

[0158] It can be understood that the atomization device 1000 provided in the embodiment of the present application includes the beneficial effects of any one or more of the atomization cores 100 described above, which will not be elaborated herein.

[0159] The above description of various embodiments tends to emphasize the differences between the various embodiments. The same or similar aspects can be referenced to each other, and for the sake of brevity, they will not be repeated herein.

[0160] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
