For those skilled in the art, the specific meaning of the above terms in the application can be understood according to the specific circumstances.

[0033] An aspect of an embodiment of the application, please refer to Figures 1 to 3 , provide a kind of atomizing core 10, comprising: ceramic matrix 11, hollow passage 111 is equipped with, for the flow of aerosol matrix is guided;Heating wire 12, embedded in the inner wall of hollow passage 111 Surface;Wherein, ceramic matrix 11 has opposite first end surface 112 and second end surface 113, form air inlet 114 on the first end surface 112, form air outlet 115 on the second end surface 113.

[0034] The ceramic base 11 is a tubular part made of ceramic material, and has a large number of micro-pores (not shown in the figure) on the wall of the tube, which are usually invisible to the naked eye but can allow the aerosol substrate to pass through. The ceramic base 11 is at least partially located in the aerosol substrate, and the aerosol substrate can enter the hollow channel 111 of the ceramic base 11 through the micro-pores on the ceramic base 11. The heating wire 12 is arranged in the hollow channel 111 and embedded on the surface of the inner wall of the ceramic base 11. The ceramic base 11 can conduct heat, and the temperature of the ceramic base 11 rises after the heating wire 12 is electrified and heated. The aerosol substrate in the ceramic base 11 becomes vapor under the heating of the heating wire 12. The vapor leaves the ceramic base 11 through the air outlet 115 under the driving of external airflow.

[0035] The atomizing core 10 described above uses the ceramic base 11 to fix the heating wire 12, and the heating wire 12 is embedded on the surface of the inner wall of the ceramic base 11, thereby forming an integrated structure with the ceramic base 11 and being not easy to deform and loosen. The aerosol substrate can enter the ceramic base 11 and contact the heating wire 12 through the micro-pores on the wall of the ceramic base 11. Therefore, after the product including the atomizing core 10 described above is assembled, the ceramic base 11 does not need to be removed, which can avoid the deformation and suspension of the heating wire 12 and further avoid the influence on the heating wire 12 and the smoking experience.

[0036] In some embodiments, please refer to Figure 1 and Figure 2 The heating wire 12 is in a mesh shape, and the ceramic base 11 is dry formed by a mold process, so that the heating wire 12 is embedded in the inner wall of the ceramic base 11 and exposed on the inner wall.

[0037] Please refer to Figure 4 The mold 70 is used to prepare the ceramic base 11, and the mold 70 includes a bottom plate 71, a first annular plate 72 and a second annular plate 73 arranged on the bottom plate 71. The first annular plate 72 is located in the second annular plate 73, and a cavity 74 between the first annular plate 72 and the second annular plate 73 is used to hold liquid ceramic material. The ceramic material can form the ceramic base 11 after solidification, and the size of the first annular plate 72 and the second annular plate 73 is determined according to the size of the ceramic base 11 required.

[0038] Before the liquid microporous ceramic material is added into the cavity 74 of the mold 70, the mesh-shaped heating wire 12 is placed in the cavity 74 and wrapped on the outside of the first annular plate 72. Since the heating wire 12 is in a mesh shape, the liquid ceramic material entering the cavity 74 will automatically fill the mesh holes of the heating wire 12. After the ceramic material is solidified, the heating wire 12 is embedded on the surface of the inner wall of the ceramic base 11. The heating wire 12 fixed by the mold process is not easy to deform and loosen.

[0039] In some embodiments, please refer to Figure 2 and Figure 5 The hollow channel 111 includes a containing portion 1111 and an air inlet portion 1112 connected with the containing portion 1111, the heating wire 12 is located in the containing portion 1111, and the air inlet portion 1112 forms an air inlet 114 on the first end face 112; wherein a normal projection contour M of the air inlet portion on the first end face is located within a normal projection contour N of the containing portion on the first end face.

[0040] It should be noted that the normal projection contour M of the air inlet portion on the first end face refers to an external contour of a projection generated by projecting the air inlet portion 1112 on the first end face 112 along a direction perpendicular to the first end face 112 using parallel projection lines with the first end face 112 as a projection plane. The normal projection contour N of the containing portion on the first end face refers to an external contour of a projection generated by projecting the containing portion 1111 on the first end face 112 along a direction perpendicular to the first end face 112 using parallel projection lines with the first end face 112 as a projection plane.

[0041] The normal projection contour M of the air inlet portion on the first end face being located within the normal projection contour N of the containing portion on the first end face indicates that the cross-sectional dimension of the air inlet portion 1112 is smaller than that of the containing portion 1111. Such a configuration is helpful to improve the suction resistance of the air inlet portion 1112.

[0042] In some embodiments, the containing portion 1111 forms an air outlet 115 on the second end face 113.

[0043] That is to say, the hollow channel 111 only includes the containing portion 1111 and the air inlet portion 1112. Such a configuration can make the internal structure of the ceramic base body 11 as simple as possible on the premise of fixing the heating wire 12 and improving the suction resistance of the air inlet portion 1112, thereby facilitating the manufacturing of the ceramic base body 11 and reducing the processing cost.

[0044] In some embodiments, the containing portion 1111 and the air inlet portion 1112 are both in a cylindrical shape, and the diameter of the air inlet portion 1112 is smaller than that of the containing portion 1111.

[0045] The inner wall of the cylindrical containing portion 1111 is free of edges and corners, which is conducive to the embedding of the heating wire 12 and will not damage the heating wire 12. The air inlet portion 1112 is configured in the same shape as the containing portion 1111, which is conducive to the processing of the ceramic base body 11. The diameter of the air inlet portion 1112 is smaller than that of the containing portion 1111, which can improve the suction resistance of the air inlet portion 1112.

[0046] In some embodiments, the diameter of the air inlet portion 1112 is between 1.1 mm and 1.3 mm.

[0047] It should be noted that the above range includes the end point value, that is, the diameter of the air inlet portion 1112 can be 1.1 mm or 1.3 mm.

[0048] When the diameter of the air inlet portion 1112 is between 1.1 mm and 1.3 mm, the flow rate and temperature of the vapor formed in the accommodation portion 1111 can be ensured to be within a reasonable range, providing a better user experience.

[0049] In some embodiments, the diameter of the air inlet portion 1112 is 1.2 mm.

[0050] At this time, the suction resistance of the air inlet portion 1112 is between 250 Pa and 350 Pa, which can provide a better user experience.

[0051] In some embodiments, the outer wall of the ceramic base 11 is cylindrical, making the appearance of the ceramic base 11 more aesthetic and facilitating the preparation of the ceramic base 11.

[0052] In some embodiments, referring to Figure 1 and Figure 2 , the heating wire 12 is provided with a positive electrode pin 13 and a negative electrode pin 14, the positive electrode pin 13 is used for electrical connection with the positive electrode of the power supply 30, and the negative electrode pin 14 is used for electrical connection with the negative electrode of the power supply 30.

[0053] The power supply 30 supplies power to the heating wire 12 through the positive electrode pin 13 and the negative electrode pin 14, so that the heating wire 12 is heated.

[0054] The embodiment also provides an electronic atomizer 60, which comprises a shell 40, an atomizing core 10 according to any one of the above embodiments arranged in the shell 40; the shell 40 is provided with a suction nozzle 41 and an air hole 42, the air outlet 115 of the atomizing core 10 faces the suction nozzle 41 and communicates with the suction nozzle 41, and the air inlet 114 of the atomizing core 10 faces the air hole 42 and communicates with the air hole 42; wherein at least part of the ceramic base 11 of the atomizing core 10 is configured to communicate with a liquid storage cavity.

[0055] The substance in the liquid storage cavity enters the hollow channel 111 of the ceramic base 11 through the tiny air holes on the tube wall of the ceramic base 11, and the heating wire 12 is heated after being powered on, so that the substance entering the ceramic base 11 becomes vapor. The user sucks from the suction nozzle 41, the external airflow enters the shell 40 from the air hole 42, then enters the ceramic base 11 through the air inlet 114, and the vapor in the ceramic base 11 is driven by the external airflow to exit the ceramic base 11 from the air outlet 115, and finally is inhaled by the user through the suction nozzle 41.

[0056] The electronic atomizer 60 comprises the same structure and advantages as the atomizing core 10 in the foregoing embodiments. The structure and advantages of the atomizing core 10 have been described in detail in the foregoing embodiments, which will not be described herein again.

[0057] In some embodiments, the housing 40 is provided with a liquid storage element 20, the liquid storage element 20 is configured to store an aerosol substrate, a first end 21 of the liquid storage element 20 faces the mouthpiece 41, and a second end 22 opposite to the first end 21 faces away from the mouthpiece 41, and the ceramic substrate 11 is located at the second end 22 of the liquid storage element 20 and protrudes from the second end 22.

[0058] Generally, when a user inhales the vapor through the mouthpiece 41, the first end 21 of the liquid storage element 20 facing the mouthpiece 41 is upward, and the second end 22 facing away from the mouthpiece 41 is downward. At this time, the aerosol substrate in the liquid storage element 20 will continuously move to the second end 22 of the liquid storage element 20 under the action of gravity. The ceramic substrate 11 is arranged at a position close to the second end 22 in the liquid storage element 20, so that as much aerosol substrate as possible in the liquid storage element 20 is inhaled into the ceramic substrate 11 for use. The ceramic substrate 11 protrudes from the second end 22 of the liquid storage element 20, so that the air inlet 114 of the ceramic substrate 11 is exposed to the liquid storage element 20, facilitating the external airflow to enter the ceramic substrate 11.

[0059] In some embodiments, the liquid storage element 20 is a liquid storage cotton, and the liquid storage cotton wraps the outer surface of the ceramic substrate 11, so that the aerosol substrate flows from the liquid storage cotton to the ceramic substrate.

[0060] The aerosol substrate is adsorbed in the liquid storage cotton, the liquid storage cotton wraps the outer surface of the ceramic substrate 11, and the aerosol substrate enters the ceramic substrate 11 through the tiny pores on the pipe wall of the ceramic substrate 11. The heating wire 12 is used to change the aerosol substrate into vapor, and the user inhales these vapors to ingest the ingredients in the aerosol substrate.

[0062] The liquid storage cotton forms a hollow channel, and the air outlet pipe 15 is embedded in the hollow channel of the liquid storage cotton and communicates with the air outlet end of the ceramic base 11. The air outlet pipe 15 isolates the liquid storage cotton from the steam formed by the atomizing core 10 and provides a flow channel for the steam. Not only can it prevent the steam from mixing into the aerosol base of the liquid storage cotton, but also can avoid waste of the steam. The air outlet pipe 15 can be made of low-cost and easy-to-process materials, thereby reducing processing cost and difficulty.

[0063] In some embodiments, the side wall of the ceramic base 11 is provided with a let-in area 116, which is configured to be nested with the end of the air outlet pipe 15.

[0064] The let-in area 116 of the ceramic base 11 is inserted into the end of the air outlet pipe 15 or is sleeved outside the end of the air outlet pipe 15 to realize the connection of the ceramic base 11 and the air outlet pipe 15.
