[0032] To at least partially resolve the problems in the relevant technologies, please refer to Figures 1 to 3 As shown, this application embodiment provides an atomizing core 10, which can be applied in the atomizer of an electronic atomizing device to heat the liquid matrix stored in the atomizer to form an aerosol for the user to inhale. The atomizing core 10 includes a substrate 100 and a heating element 200.
[0033] The substrate 100 is used to absorb and conduct the liquid matrix in the atomizer. Specifically, the substrate 100 is made of a microporous material, meaning that a large number of directional or randomly directional pores are diffusely distributed inside the substrate 100. This allows the substrate 100 to transport the liquid matrix to the heating element 200 through capillary action, improving the fluidity of the liquid matrix in the atomizing core 10 during atomization, thereby ensuring the atomization effect of the liquid matrix. The substrate 100 has a first surface 110 and a second surface 120 that are opposite to each other, such as... Figure 1 and Figure 2 As shown, the first surface 110 and the second surface 120 are arranged opposite to each other along the height direction of the substrate 100 and are connected through micropores inside the substrate 100, so that the liquid matrix can flow between the two surfaces through the liquid guiding effect of the substrate 100. The substrate 100 is provided with a ventilation opening 130 on the first surface 110. Through the ventilation opening 130 provided on the first surface 110, air from the external environment can enter the interior of the substrate 100 through the ventilation opening 130 and come into more full contact with the liquid matrix inside the substrate 100.
[0034] The heating body 200 is used to generate high temperature after being powered on, heat the liquid substrate to generate aerosol, the heating body 200 is arranged on the second surface 120 of the substrate 100, the surface of the heating body 200 has a heating area 210, and the heating area 210 is arranged around the air exchange opening 130. It can be understood that the shape, size, position arranged on the second surface 120 of the substrate 100 and the like of the heating body 200 can be flexibly adjusted and arranged according to actual use requirements, therefore, the setting position and setting range of the heating area 210 are different with the change of the heating body 200, in general, the heating area 210 is the area around the periphery of the surface of the heating body 200. The heating area 210 is arranged around the air exchange opening 130, so that the air entering the inside of the substrate 100 from the air exchange opening 130 can fully contact the liquid substrate located at the heating area 210, so that the combustion is more sufficient, and dry burning is avoided, thereby, the service life of the atomization core 10 can be relatively prolonged, the taste of the aerosol before and after can be kept consistent, and the use experience of consumers can be improved.
[0035] The atomization core 10 provided by the embodiment of the present application is arranged by arranging the air exchange opening 130 on the first surface 110 of the substrate 100, arranging the heating body 200 on the second surface 120 of the substrate 100, and arranging the heating area 210 on the surface of the heating body 200 around the air exchange opening 130, so that in the atomization working process of the atomization core 10, the air in the external environment can enter the inside of the substrate 100 through the air exchange opening 130 and fully contact the liquid substrate located at the heating area 210, so that the combustion is more sufficient, and dry burning is avoided, thereby, the service life of the atomization core 10 can be relatively prolonged, the taste of the aerosol before and after can be kept consistent, and the use experience of consumers can be improved.
[0036] The form, number, arrangement mode and the like of the air exchange opening 130 arranged on the first surface 110 of the substrate 100 are not limited, for example, as shown in FIGS. 1 and 2, in some embodiments, the air exchange opening 130 includes a plurality of air exchange holes 131 arranged at intervals, and the cross-sectional shape of the air exchange hole 131 on the first surface 110 is circular. Figure 2 and Figure 3 As shown in FIGS. 1 and 2, in some embodiments, the air exchange opening 130 includes a plurality of air exchange holes 131 arranged at intervals, and the cross-sectional shape of the air exchange hole 131 on the first surface 110 is circular. The number and arrangement position of the air exchange hole 131 can be adjusted according to actual use conditions, so that the air in the external environment can enter the inside of the substrate 100 and cover the required positions, and the use effect is good.
[0037] On the basis of the above-mentioned embodiments, optionally, each air exchange hole 131 is arranged in a row along a first direction x and in a column along a second direction y on the first surface 110, the first direction x and the second direction y are perpendicular to each other, that is, each air exchange hole 131 is arranged in a rectangular array in multiple rows and multiple columns. Of course, in other embodiments, each air exchange hole 131 can also be arranged in other ways.
[0038] Please refer to Figure 1 and refer to Figure 4 and Figure 5 In some embodiments, the ventilation opening 130 optionally comprises a plurality of ventilation grooves 132 arranged at intervals from each other, and the cross-sectional shape of the ventilation grooves 132 on the first surface 110 is long strip-shaped. The coverage of the ventilation grooves is relatively wider, so that the air in the external environment can enter the inside of the base body 100 in the largest possible amount, and the use effect is good.
[0039] On the basis of the above-mentioned embodiments, the ventilation grooves 132 are arranged along the first direction x on the first surface 110, and the adjacent two ventilation grooves 132 are arranged at intervals from each other along the second direction y, and the first direction x and the second direction y are perpendicular to each other. That is, each ventilation groove 132 is arranged in a linear array. Of course, in other embodiments, each ventilation groove 132 can also be arranged in other ways.
[0040] Please refer to Figure 1 and refer to Figure 3 and Figure 5 In some embodiments, the heating body 200 optionally comprises a main body part 220 and an extension part 230 connected to each other, the main body part 220 is at least partially fixed to the second surface 120, one end of the extension part 230 is connected to the main body part 220, the other end of the extension part 230 passes through the second surface 120 and is embedded in the base body 100; the orthographic projection of the ventilation opening 130 on the first surface 110 falls within the orthographic projection of the main body part 220 on the first surface 110.
[0041] The orthographic projection of the ventilation opening 130 on the first surface 110 falls within the orthographic projection of the main body part 220 on the first surface 110, that is, the coverage area of the orthographic projection pattern of the main body part 220 on the first surface 110 is relatively large, and the coverage area of the orthographic projection pattern of the ventilation opening 130 on the first surface 110 is relatively small and is completely covered by the orthographic projection pattern of the main body part 220 on the first surface 110. In this way, the air entering the inside of the base body 100 from the ventilation opening 130 can fully contact the liquid substrate at the heating area 210 on the main body part 220 and the extension part 230, so that the combustion is more sufficient, and dry burning is avoided.
[0042] In order to adapt to the shape and structure of the base body 100 and at the same time increase the coverage area of the extension part 230 in the heating body 200, in some embodiments, the number of the extension part 230 is an even number, and each extension part 230 is respectively arranged symmetrically on opposite sides of the main body part 220.
[0043] As Figure 2 and Figure 3As shown, in some embodiments, optionally, when the ventilation opening 130 includes a ventilation hole 131, the ventilation hole 131 is a blind hole, pointing from the first surface 110 to the second surface 120. The thickness dimension of the substrate 100 is greater than the sum of the depth dimension of the blind hole and the length dimension of the extension 230, that is, the ventilation hole 131 and the extension 230 of the heating element 200 do not coincide in the thickness direction of the substrate 100.
[0044] like Figure 4 and Figure 5 As shown, when the ventilation opening 130 includes the ventilation groove 132, the ventilation groove 132 is a blind groove, pointing from the first surface 110 to the second surface 120. The thickness of the base 100 is greater than the sum of the depth of the blind groove and the length of the extension 230. That is, the ventilation groove 132 and the extension 230 of the heating element 200 do not coincide in the thickness direction of the base 100.
[0045] In some embodiments, the substrate 100 may optionally be made of microporous ceramic. Microporous ceramic refers to a ceramic body containing a large number of open or closed micropores inside or on its surface, with pore sizes typically in the micrometer or submicrometer range. The surface of microporous ceramic is hygroscopic; by rationally controlling the porosity, micropore size, specific surface area, and water content of the microporous ceramic, the humidity of localized areas can be adjusted, thereby improving the performance of the atomizing core 10.
[0046] Based on the same inventive concept, this application also provides an atomizer, which includes: the atomizing core 10 as in any of the above embodiments.
[0047] Because the atomizing core 10 in any of the above embodiments is used, the liquid matrix in the atomizer provided in this application embodiment is burned more completely, avoiding dry burning. As a result, the service life of the atomizing core 10 can be extended, and the taste of the aerosol can be kept consistent before and after, thus improving the user experience.
[0048] In the above embodiments, the descriptions of each embodiment have different focuses. For parts that are not described in detail or recorded in a certain embodiment, please refer to the relevant descriptions of other embodiments.
[0049] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
