[0036] See also Figure 1 and Figure 2 The present application provides an atomizer core 100, which includes an oil-conducting matrix 10 and a heating element 11, wherein the oil-conducting matrix 10 is in contact with the heating element 11. An aerosol-generating matrix is adsorbed on the oil-conducting matrix 10, and the heating element 11 is energized to atomize the aerosol-generating matrix on the oil-conducting matrix 10 to form an aerosol for inhalation by a user.
[0037] Specifically, see Figure 1 and Figure 2 The oil-conducting substrate 10 has a first surface 101 and a second surface 102 opposite to each other along the thickness direction thereof, and the second surface 102 is recessed to form a groove 103. The heating element 11 includes a heating portion 111, which is disposed on the first surface 101. The outer contour of the positive projection of the heating portion 111 on the first surface 101 defines an atomization area 12 (such as Figure 5The orthographic projection of the groove 103 on the first surface 101 at least partially falls into the atomization area 12. Specifically, the oil-conducting matrix 10 is a porous structure, and the aerosol-generating matrix gradually penetrates from the second surface 102 to the first surface 102, so that the micropores of the entire oil-conducting matrix 10 are filled with the aerosol-generating matrix.
[0038] In the traditional design, affected by the thickness and porosity of the oil-conducting matrix 10, the aerosol generating matrix conducts oil and penetrates from the area aligned with the atomization area 12 on the second surface 102 to the atomization area 12 of the first surface 102 at a slow speed, resulting in a slow supply of the aerosol generating matrix in the atomization area 12 and a core-burning phenomenon.
[0039] In this application, see Figure 2 and Figure 6 By providing the groove 103 on the second surface 102, the aerosol generating matrix diffuses from the groove 103 to the first surface 101, and the oil guide path is shortened. The specific length of the oil guide path in the high-speed oil guide area becomes the difference between the thickness of the oil guide matrix 10 and the depth of the groove 103, thereby improving the oil guide rate of the oil guide matrix 10 and reducing the probability of the atomizer core 100 being stuck due to insufficient oil supply in the atomization area 12.
[0040] Specifically, see Figure 5 When the heating element 11 is powered on, the main heat of the heating element 11 is concentrated in the heating portion 111. The contour of the positive projection of the heating portion 111 on the first surface 101 defines the atomization area 12, so that the heat in the atomization area 12 is relatively concentrated. Figure 6 The outer contour of the positive projection of the groove 103 on the first surface 101 defines a high-speed oil guide area 14 (such as Figure 6 The high-speed oil guide area 14 completely falls into the atomization area 12, so as to quickly supply oil to the atomization area 12. In this way, the atomization area 12 has high heat and high oil guide speed, thereby preventing the core from being burnt.
[0041] In some embodiments, see Figure 1 and Figure 2 , the orthographic projection of the groove 103 on the first surface 101 completely falls into the atomization area 12. In this way, all the aerosol-generating substrates diffused to the first surface 101 through the groove 103 can directly enter the atomization area 12, and are atomized to form aerosols in time under the heat generated by the heating element 11. In this way, the oil conduction rate of the oil-conducting substrate 10 can be improved and the probability of core sticking can be reduced.
[0042] In some embodiments, see Figure 2 , the thickness of the oil-conducting base 10 is H1, the depth of the groove 103 is H2, and 0.54H1≤H2≤0.67H1.
[0043] It can be understood that when 0.54H1≤H2≤0.67H1, while being able to achieve rapid diffusion of the aerosol generating matrix, it is also possible to ensure that the oil conducting matrix 10 has sufficient structural strength, thereby increasing the service life of the oil conducting matrix 10.
[0044] It should be noted that the numerical relationship between the thickness H1 of the oil-conducting matrix 10 and the depth H2 of the groove 103 is obtained through experimental testing, and the parameters, steps, etc. related to the experimental testing of the numerical relationship between the thickness H1 of the oil-conducting matrix 10 and the depth H2 of the groove 103 are conventional techniques of those skilled in the art and will not be elaborated here.
[0045] In some embodiments, see Figure 1 and Figure 2 , the orthographic projection of the groove 103 on the first surface 101 completely falls into the atomization area 12. In the width direction of the oil-conducting substrate 10, the width of the atomization area 12 is L1, the width of the groove 103 is L2, and 0.6L1≤L2≤0.7L1.
[0046] It is understandable that the width of the groove 103 needs to be smaller than the atomization area 12 to prevent the aerosol generating matrix diffused from the groove 103 to the first surface 101 from diffusing to the outside of the atomization area 12 and failing to be atomized in time, resulting in excessive aerosol generating matrix and causing a "gurgling" sound when the user inhales.
[0047] It should be noted that the numerical relationship between the width L1 of the atomization area 12 and the width L2 of the groove 103 is obtained through experimental testing, and the parameters, steps, etc. related to the experimental testing of the numerical relationship between the width L1 of the atomization area 12 and the width L2 of the groove 103 are conventional techniques of those skilled in the art and will not be elaborated here.
[0048] In some embodiments, see Figure 2 The thickness of the oil-conducting substrate 10 is H1, and 2.4 mm ≤ H1 ≤ 2.6 mm.
[0049] Specifically, the area on the first surface 101 other than the atomized area 12 is the non-atomized area 1312. When 2.4 mm ≤ H1 ≤ 2.6 mm, the rate at which the aerosol generating substrate is introduced from the second surface 102 to the non-atomized area 1312 can be controlled to reduce the situation where the oil conduction rate of the non-atomized area 1312 is too fast, the oil is oversupplied, and a "gurgling" sound is generated. That is, within this thickness range, the oil conduction speed of the non-atomized area can be suppressed.
[0050] In some embodiments, see Figure 1 and Figure 2The oil-conducting matrix 10 is a ceramic matrix, and the porosity of the oil-conducting matrix 10 is P, 50%≤P≤60%, and the pore size is D, 10um≤D≤20um.
[0051] It can be understood that the aerosol generating matrix is diffused through the micropores on the oil conducting matrix 10. When 50%≤P≤60% and 10um≤D≤20um, the number and size of the micropores on the oil conducting matrix 10 can ensure that the aerosol generating matrix has a suitable diffusion rate and diffusion amount per unit time, thereby improving the oil conducting rate of the oil conducting matrix 10 and reducing the probability of the atomizing core 100 being stuck due to insufficient oil supply in the atomizing area 12.
[0052] In some embodiments, see Figure 2 and Figure 3 The groove 103 includes a plurality of sub-grooves 1031 , and all the sub-grooves 1031 of the same groove 103 are arranged along the length direction or the width direction of the oil guide base 10 .
[0053] It can be understood that the orthographic projections of all sub-grooves 1031 of the same groove 103 on the first surface 101 completely fall within the atomization area 12. In the width direction of the oil-conducting substrate 10, the distance between the two farthest-spaced sub-grooves 1031 in all the sub-grooves 1031 along the width direction of the oil-conducting substrate 10 is the width L2 of the groove 103.
[0054] For example, see Figure 1 and Figure 3 The groove 103 includes two sub-grooves 1031 , and the two sub-grooves 1031 are arranged at intervals along the width direction of the oil guide base 10 .
[0055] In some embodiments, the heating element 11 has multiple heating parts 111, and the multiple heating parts 111 are all arranged on the first surface 101, and the outer contour of the orthographic projection of each heating part 111 on the first surface 101 defines the atomization area 12. The multiple heating elements 11 can be powered on and generate heat at the same time to simultaneously atomize the aerosol-generating matrix passing through the multiple atomization areas 12, thereby effectively improving the working efficiency of the atomization core 100 and improving the user experience.
[0056] The second surface 102 of the oil-conducting substrate 10 is recessed to form a plurality of grooves 103 . The grooves 103 correspond to the atomization regions 12 one by one. The orthographic projections of the grooves 103 on the first surface 101 fall into the corresponding atomization regions 12 .
[0057] In some embodiments, see Figure 1 and Figure 4 The heating element 11 further includes an electrode portion 112 , which is disposed on the first surface 101 and arranged at opposite ends of the heating portion 111 along the length direction of the oil-conducting substrate 10 .
[0058] It can be understood that the electrode portion 112 is used to connect to an external power source and to conduct electrical energy to the heating portion 111, so that the heating element 11 is energized and the aerosol generating matrix on the oil-conducting matrix 10 is atomized to form an aerosol for the user to inhale.
[0059] In some embodiments, see Figure 1 and Figure 4 The heating element 11 further includes a heating embedded portion 113 and an electrode embedded portion 114, the heating embedded portion 113 is connected to the heating portion 111, the electrode embedded portion 114 is connected to the electrode portion 112, and the heating embedded portion 113 and the electrode embedded portion 114 are both pre-buried in the oil-conducting matrix 10. In this way, the heating embedded portion 113 and the electrode embedded portion 114 can achieve a stable connection between the heating element 11 and the oil-conducting matrix 10.
[0060] The embodiment of the present application further provides an atomization device, which includes the atomization core 100 in the above embodiment.
[0061] The atomization device in the present application has the effects brought by any of the above-mentioned embodiments, so it will not be described in detail here.
[0062] The atomizer core 100 and the atomizer device are provided with the groove 103 on the second surface 102, and the aerosol generating matrix diffuses from the groove 103 to the first surface 101, and the oil guide path is shortened. The specific length of the oil guide path becomes the difference between the thickness of the oil guide matrix 10 and the depth of the groove 103, thereby improving the oil guide rate of the oil guide matrix 10 and reducing the probability of the atomizer core 100 being stuck due to insufficient oil supply in the atomization area 12.
[0063] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0064] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
