[0061] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0062] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0063] In one embodiment, please refer to Figures 1 to 3 The atomizer core includes an oil-conducting matrix and a heating element 1 , wherein the oil-conducting matrix includes a first porous matrix 2 and a second porous matrix 3 .

[0064] Please refer to Figures 1 to 3The first porous substrate 2 has an atomization channel 22, and the atomization channel 22 can provide aerosol flow. At least part of the heating element 1 is in the atomization channel 22, and the heating element 1 heats and atomizes the aerosol generating oil to generate aerosol, and the generated aerosol can flow in the atomization channel 22, so that the generated aerosol can be sucked out.

[0065] In order to increase the oil transfer rate of the oil transfer matrix, please refer to Figure 2 , a thinning groove 24 is provided on the side of the first porous substrate 2 away from the atomization channel 22. The second porous substrate 3 is at least partially accommodated in the thinning groove 24, and the oil conduction rate of the second porous substrate 3 is greater than the oil conduction rate of the first porous substrate 2. In this way, the thickness of the first porous substrate 2 is locally thinned by the thinning groove 24, and the second porous substrate 3 with a faster oil conduction rate is arranged in the thinning groove 24, so that the oil conduction rate of the entire oil conduction substrate can be improved. In addition, compared with directly thinning the overall wall thickness of the first porous substrate 2, the method of grooving the first porous substrate 2 can ensure the overall strength of the first porous substrate 2.

[0066] It should be noted that the thinning groove 24 of the present application is a type of groove. Compared with the groove formed by the local concave bending of the first porous matrix 2, the thinning groove 24 can thin the wall thickness of the first porous matrix 2, that is, the thinning groove 24 can thin the thickness of the first porous matrix 2 between the atomization channel 22 and the thinning groove 24, thereby improving the overall oil conduction rate after the thinning groove 24 is installed into the second porous matrix 3.

[0067] The thinning groove 24 can be formed in any feasible manner. For example, in one embodiment, please refer to Figure 2 , the thinning groove 24 is a continuously extending groove. The continuously extending groove can realize continuous oil conduction, facilitate processing, and also facilitate adaptation with the second porous matrix 3. For another example, in one embodiment, the thinning groove 24 can also be a groove distributed in a point shape on the first porous matrix 2. For another example, in one embodiment, the thinning groove 24 can also be a long strip groove, wherein a plurality of thinning grooves 24 are arranged in a straight line in the length direction of the thinning groove 24 and there is a gap between adjacent thinning grooves 24.

[0068] Regarding the single continuous extending groove form, one embodiment, please refer to Figures 1 to 3 , the thinning groove 24 is a spiral groove 240 extending circumferentially around the first porous substrate 2. Specifically, in one embodiment, the thinning groove 24 has a spiral groove opening 241, and the spiral groove opening 241 faces away from the atomization channel 22 of the first porous substrate 2. After the spiral groove 240 is opened on the first porous substrate 2, the strength is minimally affected, and the spiral groove 240 extends continuously, which is convenient for the loading of the second porous substrate 3. In one embodiment, in addition to the spiral groove 240, a straight groove can also be used, and the straight groove extends along the axial direction of the first porous substrate 2. When a straight groove is used, the number of the straight grooves can be more than two.

[0069] In one embodiment, please refer to Figure 2 , the thinning groove 24 is a through groove extending from one end of the first porous substrate 2 to the other end. The through groove is more convenient for processing the thinning groove 24. Specifically, in one embodiment, the spiral groove 240 is a spiral through groove. In some other embodiments, in addition to using a through groove, at least one section at both ends of the thinning groove 24 can also be closed.

[0070] In one embodiment, please refer to Figures 1 to 3 The second porous matrix 3 includes a filling portion 30 and an outer package portion (not shown in the figure), and the filling portion 30 is continuously filled in the spiral groove 240 in a spiral shape, and the groove side wall of the spiral groove 240 can play a role in supporting the filling portion 30. The outer package portion wraps the first porous matrix 2, and the outer package portion and the filling portion 30 are separately arranged, so that it is convenient to load the filling portion 30 into the spiral groove 240, and the outer package portion can prevent the filling portion 30 from falling off. In some other embodiments, in addition to the separate arrangement of the outer package portion and the filling portion 30, they can also be integrally formed, and in this case, the second porous matrix 3 is more efficiently formed.

[0071] In some other embodiments, the filling part 30 can also be integrally formed with the outer part, and the filling part 30 is a protrusion intermittently arranged on the outer part. In some other embodiments, the entire second porous matrix 3 is filled in the spiral groove 240, and the outer part is not required.

[0072] In one embodiment, please refer to Figures 1 to 3 , the second porous matrix 3 fills the thinning groove 24. In some other embodiments, the second porous matrix 3 may not fill the thinning groove 24, for example, the thinning groove 24 is a continuously extending through groove, and the filling part of the second porous matrix 3 is intermittently filled in the thinning groove 24.

[0073] In one embodiment, in order to facilitate the installation of the filling part 30, the spiral groove 241 is a constricted opening, so that the filling part 30 is not easy to escape from the groove of the spiral groove 240, and the stability is better.

[0074] Further, in one embodiment, please refer to Figures 1 to 3 , the number of the spiral groove 240 is one. In some other embodiments, the number of the spiral grooves 240 is selected as needed, for example, the number of the spiral grooves 240 can be at least two, and each spiral groove 240 extends in parallel, such as a double spiral groove, three spiral grooves, etc.

[0075] Further, regarding the groove type of the thinning groove 24, in one embodiment, please refer to Figures 1 to 3, the thinning groove 24 is an arc-shaped groove with an arc-shaped cross section. In this way, the groove wall surface of the spiral groove 240 is a smooth curved surface, which is not easy to cause stress concentration, thereby improving the strength of the first porous matrix 2. Specifically, in some embodiments, the cross section of the thinning groove 24 can be a superior arc, a semi-arc, or a inferior arc. In some other embodiments, the cross section of the thinning groove 24 can also be a polygon.

[0076] In one embodiment, the first porous substrate 2 is an inorganic material substrate, and the second porous substrate 3 is an organic material substrate or an inorganic material substrate. Further, in one embodiment, the first porous substrate 2 is a porous ceramic substrate or a porous glass substrate or a porous carbon substrate, and the second porous substrate 3 is a porous ceramic substrate or a porous glass substrate or a porous carbon substrate or a cotton substrate. In one embodiment, when the second porous substrate 3 adopts a soft substrate, in order to ensure strength, the first porous substrate 2 adopts a hard substrate, for example, the second porous substrate 3 adopts a cotton substrate, and the first porous substrate 2 adopts a porous ceramic substrate or a porous glass substrate.

[0077] Specifically, in one embodiment, the first porous substrate 2 is a porous ceramic substrate, and the second porous substrate 3 is a cotton substrate. In this way, the porous ceramic substrate has a higher ignition point, the cotton substrate is not in direct contact with the heating element 1, and the cotton substrate is not easily burnt. In addition, the second porous substrate 3 using a cotton substrate is easier to implement in terms of process than using a hard substrate. It only needs to directly fill the cotton on the thinning groove 240 of the first porous substrate 2.

[0078] Further, in one embodiment, please refer to Figure 3 The first porous substrate 2 is a substrate tube, and the inner hole of the substrate tube forms an atomization channel 22. At least part of the heating element 1 is arranged on the inner wall 21 of the first porous substrate 2, and the thinning groove 24 is arranged on the outer wall 23 of the first porous substrate 2. The second porous substrate 3 is located outside the first porous substrate 2. By arranging the heating element 1 on the inner wall 21 of the first porous substrate 2 to heat the aerosol generating oil, the second porous substrate 3 will not be burned. Furthermore, in one embodiment, the heating element 1 can be embedded in the inner wall 21 of the first porous substrate 2. In some other embodiments, the heating element 1 can also be in contact with the inner wall surface of the first porous substrate 2.

[0079] In one embodiment, the heating element 1 is a heating wire, a heating net or a heating film. Figure 3 The heating element 1 is a spiral heating wire. Specifically, the spiral heating wire is a nautilus-shaped heating wire, and the nautilus-shaped heating wire is embedded in the first porous matrix 2.

[0080] Specifically, in one embodiment, please refer to Figure 4The heating element 1 is a MESH mesh heating wire, and the MESH mesh heating wire is embedded in the first porous matrix 2. The MESH mesh heating wire has a larger atomization area and a better atomization effect than the nautilus-shaped heating wire.

[0081] In one embodiment, in the atomizer core with the thinning groove 24, there are at least three paths for the aerosol-generating oil to pass through, see Figure 3 The first path is to conduct to the bottom surface of the thinning groove 24 through the second porous matrix 3, and then enter the first porous matrix 2, and be heated and atomized after contacting the heating element 1. The second path is to conduct to the side surface of the thinning groove 24 through the second porous matrix 3, and then enter the first porous matrix 2 from the side surface of the groove, and be heated and atomized after contacting the heating element 1. The third path is to enter the first porous matrix 2 through the outer side surface of the first porous matrix 2, and be heated and atomized after contacting the heating element 1. Among them, the first path and the second path have higher oil conduction rates, which reduces the core sticking problem caused by insufficient supply of aerosol-generating oil or concentrated temperature, increases the service life, and improves the taste restoration.

[0082] In order to verify the effect of the atomizer core of the present application, in one embodiment, compared with the atomizer cores in the prior art that all use porous ceramic substrates and cotton substrates, in this embodiment, the first porous substrate 2 uses a porous ceramic substrate, and the second porous substrate 3 uses a cotton substrate. The oil conduction rate of the atomizer core and the amount of aerosol generated are tested and analyzed, and the results are as follows:

[0083] Table 1 Atomizer core performance comparison table

[0084]

[0085] Comparative analysis shows that the atomizer core that uses all cotton matrices has the best oil conduction rate, followed by the atomizer core that uses a porous ceramic matrix and a cotton matrix in this embodiment, and finally the atomizer core that uses a porous ceramic matrix completely. In this embodiment, the combined atomizer core using a porous ceramic matrix and a cotton matrix has a relatively high oil conduction rate on the one hand, and on the other hand, atomization is performed on the surface of the porous ceramic matrix, and there will be no problem of core sticking. Since the atomizer core that uses a porous ceramic matrix completely has a relatively low oil conduction rate, when continuously inhaled, it may cause the core to stick due to insufficient oil supply. The atomizer core that uses a cotton matrix completely has the shortest working life because the oil-conducting cotton itself has a relatively low ignition point.

[0086] In a specific embodiment of an oil-conducting matrix, the structure of the oil-conducting matrix is ​​the same as that of the oil-conducting matrix described in any of the above embodiments, and will not be described in detail.

[0087] In a specific embodiment of an atomization bin, the atomization bin comprises an oil storage cavity and an atomization core as described in any of the above embodiments. The oil storage cavity is used to store aerosol generating oil, and the atomization core is communicated with the oil storage cavity to allow the aerosol generating oil to enter the atomization core.

[0088] It should be noted that the conduction, communication and interconnection described in the present application are not limited to empty channels through which aerosol generating oil can pass, but also include channels filled with porous materials through which aerosol generating oil can pass.

[0089] In one embodiment, the oil storage cavity is filled with a porous oil storage matrix, and the aerosol generating oil is adsorbed in the porous oil storage matrix. The porous oil storage matrix is ​​connected to the atomizing core, so that the aerosol generating oil enters the atomizing core from the porous oil storage matrix and then contacts the heating element.

[0090] In a specific embodiment of an atomizing device, the atomizing device includes an atomizing bin and a power supply for supplying power to the atomizing bin. The atomizing bin includes an oil storage cavity and an atomizing core as described in any of the above embodiments. The oil storage cavity is used to store aerosol generating oil, and the atomizing core is connected to the oil storage cavity so that the aerosol generating oil can enter the atomizing core.
