Obviously, the described implementation methods are only part of the implementation methods of the present application, rather than all the implementation methods. Based on the implementation methods in the present application, all other implementation methods obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.

[0032] In the current atomization device, oil-absorbing cotton is usually arranged to absorb the atomized material in the oil bin. However, in the process of heating the atomized material in the atomized oil-absorbing cotton, the oil-absorbing cotton is easily carbonized due to the material of the oil-absorbing cotton, which affects the service life of the oil-absorbing cotton. Moreover, the oil-absorbing cotton is easily carbonized after being heated, which affects the atomization purity of the atomized material, that is, affects the atomization quality of the atomized material. In view of the shortcomings of the prior art, the present application provides an electronic atomizer and a heating core group.

[0033] See also Figure 1 , Figure 1 This is a structural diagram of an electronic atomizer provided in one embodiment of the present application.

[0034] The embodiment of the present application takes a cylindrical micro-electronic atomizer 100 as an example to explain the technical solution of the present application in detail. It should be understood that the electronic atomizer 100 to which the technical solution of the present application is applicable includes but is not limited to medical atomizers, household atomizers, humidifiers, micro-atomizers, etc.

[0035] The electronic atomizer 100 provided in this embodiment includes a heating core group 10, a power supply 20, an oil tank 30 and a shell 40. The heating core group 10, the power supply 20 and the oil tank 30 are all arranged in the shell 40. The heating core group 10 is electrically connected to the power supply 20. The power supply 20 is used to supply power to the heating core group 10 so that the heating core group 10 generates heat after being powered on. The oil tank 30 is used to accommodate the atomized material. The oil tank 30 is connected to the heating core group 10. The atomized material in the oil tank 30 can flow into the heating core group 10 under the action of the heating core group 10. Finally, the atomized material is atomized to form an atomized gas by the heating of the heating core group 10. In the electronic atomizer 100 provided in this embodiment, the oil tank 30 is used to contain the liquid atomized material, and the liquid atomized material in the oil tank 30 can flow into the heating core group 10.

[0036] In the electronic atomizer 100 provided in this embodiment, when in working state, the liquid to be atomized in the oil tank 30 flows into the heating core group 10, and the liquid to be atomized is converted from liquid to gaseous by the heating of the heating core group 10, generating inhalable atomized gas. At the same time, external air enters from the middle of the heating core group 10. The air flow generated by suction brings about a pressure difference, which can accelerate the penetration of the liquid to be atomized from the oil tank 30 into the heating core group 10, so that more liquid to be atomized is converted into atomized gas, and the atomized gas and air mixture enters the user's mouth through the mouthpiece of the electronic atomizer 100.

[0037] It can be understood that in some embodiments, the electronic atomizer 100 can be an electronic cigarette, which includes a heating core group 10, a power supply 20, an oil tank 30 and a shell 40. The heating core group 10, the power supply 20 and the oil tank 30 are all arranged in the shell 40, the heating core group 10 is electrically connected to the power supply 20, the power supply 20 is used to supply power to the heating core group 10, so that the heating core group 10 generates heat after being powered on, the oil tank 30 is used to accommodate the atomized material, the oil tank 30 is connected to the heating core group 10, and the liquid smoke oil in the oil tank 30 can flow into the heating core group 10 under the action of the heating core group 10, and finally the liquid smoke oil is atomized to form smoke through the heating of the heating core group 10.

[0038] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 , Figure 2 is a structural diagram of a heating core group provided in one embodiment of the present application. Figure 3 This is a structural diagram of a metal oil absorbent provided in one embodiment of the present application. Figure 4 This is a structural diagram of a heating wire provided in one embodiment of the present application.

[0039] The heating core group 10 provided in the present application is used to absorb and heat the atomized material to be atomized. The heating core group 10 includes a metal oil absorbent 11 and a heating wire 13, wherein the heating wire 13 is wound around the periphery of the metal oil absorbent 11 and is insulated from the metal oil absorbent 11. The metal oil absorbent 11 has a plurality of oil absorption pores (not shown in the figure), the oil absorption pores are used to absorb the atomized material located in the oil bin 30, and the heating wire 13 is used to generate heat and atomize the atomized material under the power supply of the power supply 20. In this embodiment, an insulating coating is provided on the heating wire 13 to insulate the heating wire 13 from the metal oil absorbent 11. The metal oil absorbent 11 is formed by winding and extruding one or more metal wires, and the oil absorption pores are formed after the metal wires are extruded.

[0040] It can be understood that in some other embodiments, an insulating coating is provided on the metal wire forming the metal oil absorbent 11 , and an insulating coating is also provided on the heating wire 13 , so as to insulate the heating wire 13 from the metal oil absorbent 11 .

[0041] The heating core group 10 provided in this embodiment replaces the oil absorbing cotton with the metal oil absorbing material 11. Since the metal oil absorbing material 11 is made of metal material, it is not easy to carbonize after being heated, and the service life of the heating core group 10 can be improved. At the same time, since the metal oil absorbing material 11 is not easy to carbonize and produce dust and other impurities after being heated, it is beneficial to improve the purity of the atomized material to be atomized by the heating core group 10, and then improve the atomization quality of the atomized material to be atomized by the heating core group 10. Moreover, the metal oil absorbing material 11 is formed by extrusion, so that the overall processing technology of the heating core group 10 is simple and the processing cost is low.

[0042] It should be understood that the material of the metal oil absorbent 11 provided in this embodiment includes but is not limited to 304 or 306 stainless steel, and the metal oil absorbent 11 is formed by extrusion according to specifications.

[0043] In some embodiments, the metal oil absorbent 11 includes a mesh structure. In other words, the metal oil absorbent 11 is formed by extrusion of a metal mesh, and the metal mesh is extruded to form oil absorbing pores. The metal oil absorbent 11 is formed by extrusion of a metal mesh, and the metal mesh is not easy to fall apart, so that the structure of the metal oil absorbent 11 is more stable, which is conducive to improving the stability of heating and atomization of the heating core group 10.

[0044] See also Figure 3The metal oil absorbent 11 has a recess 111, which is used to accommodate part of the material to be atomized, and at least part of the heating wire 13 is accommodated in the recess 111. By setting the recess 111 and at least part of the heating wire 13 being located in the recess 111, the distance between the heating wire 13 and the material to be atomized is closer, so that the material to be atomized inside the metal oil absorbent 11 is heated more evenly, and the atomization of the material to be atomized is more complete, which is conducive to improving the atomization efficiency of the material to be atomized.

[0045] Specifically, the depression 111 is semicircular, and the inner wall surface of the depression 111 is in a continuous curved surface. The oil conduction performance of the metal oil absorbent 11 is improved by designing the depression 111 with the inner wall surface of the depression 111 being in a continuous curved surface.

[0046] It can be understood that in some other embodiments, the recess 111 can be in a "U" shape, a "V" shape, a "concave" shape (rectangular), etc., and the present application does not impose any limitation on this.

[0047] See also Figure 3 In the heating core group 10 provided in this embodiment, the rigidity of the heating wire 13 is relatively large, and the heating wire 13 is wound on the metal oil absorbing material 11 in a cylindrical shape, that is, the portion located between the two ends of the heating wire 13 is spaced apart from the bottom of the recess 111 of the metal oil absorbing material 11. By making the rigidity of the heating wire 13 relatively large, the stability of the heating wire 13 wound on the metal oil absorbing material 11 is better. At the same time, the friction contact between the heating wire 13 and the metal oil absorbing material 11 can be reduced, thereby ensuring the insulation performance between the heating wire 13 and the metal oil absorbing material 11.

[0048] In some other embodiments, the heating wire 13 is made to have a relatively large rigidity, and the middle portion between the two ends of the heating wire 13 fits the bottom of the depression 111 of the metal oil absorbent 11. In other words, in order to adapt to the shape of the depression 111 of the metal oil absorbent 11, the radial dimensions of the two ends of the heating wire 13 are relatively large, and the radial dimension of the middle portion of the heating wire is relatively small.

[0049] It should be understood that in some embodiments, the heating wire 13 is made with a relatively small rigidity, and the heating wire 13 is wound around the metal oil sorbent 11 in a curved cylindrical shape. In other words, the middle portion between the two ends of the heating wire 13 is bent toward the bottom of the depression 111 of the metal oil sorbent 11 and fits with the bottom of the depression 111 of the metal oil sorbent 11.

[0050] See also Figure 2 and Figure 4, the number of turns of the heating wire 13 wound on the metal oil absorbent 11 is N, and the number of turns N satisfies: 4≤N≤8. As the number of turns of the heating wire 13 is more, its resistance is greater, and the heating power is greater; the fewer turns of the heating wire 13 are wound, its resistance is smaller, and the heating power is smaller. By limiting the number of turns of the heating wire 13 on the metal oil absorbent 11, the heating atomization power of the heating wire 13 is limited. Prevent the atomization inhalation experience from being affected by too small or too large heating atomization power.

[0051] In a specific embodiment, the number of turns of the heating wire 13 around the metal oil absorbent 11 is 6.

[0052] See also Figure 2 and Figure 4 The distance between the first circle of the heating wire 13 wound on the metal oil sorbent 11 and the last circle of the heating wire 13 wound on the metal oil sorbent 11 is D, and the distance D satisfies: 4mm≤D≤6mm. The heating power of the heating wire 13 is limited by limiting the distance between the first circle of the heating wire 13 wound on the metal oil sorbent 11 and the last circle of the heating wire 13 wound on the metal oil sorbent 11.

[0053] Specifically, the spacing between any two adjacent turns of the heating wire 13 is equal. By limiting the spacing between any two adjacent turns of the heating wire 13 to be equal, the heating power of different positions of the heating wire 13 is made the same, so that the heating wire 13 can atomize the atomized material in the metal oil absorbent 11 more uniformly, which is beneficial to improving the quality of the atomized material by the heating wire 13.

[0054] It can be understood that in some other embodiments, the spacing between two adjacent turns of the heating wire 13 may not be equal. The designer may set the spacing between two adjacent turns of the heating wire 13 according to the shape of the metal oil absorbent 11. For example, the heating wire 13 wound around the position with a larger radial dimension of the metal oil absorbent 11 is more dense, and the heating wire 13 wound around the position with a smaller radial dimension of the metal oil absorbent 11 is more sparse, so that the heating wire 13 can more completely atomize the atomized material in the metal oil absorbent 11.

[0055] In a specific embodiment, the distance between the first circle of the heating wire 13 wound around the metal oil sorbent 11 and the last circle of the heating wire 13 wound around the metal oil sorbent 11 is 5 mm.

[0056] See also Figure 1 , Figure 5 and Figure 6 , Figure 5 is a structural diagram of another heating core group provided in one embodiment of the present application. Figure 6 This is a structural diagram of another heating core group provided in an embodiment of the present application.

[0057] In one embodiment, the heating wire 13 includes a first heating wire 131 and a second heating wire 132 , both of which are wound around the metal oil absorbent 11 , and are used to generate heat and atomize the atomized material.

[0058] The first heating wire 131 and the second heating wire 132 are electrically connected to the power supply 20, respectively, and the user can control the power on and off between the first heating wire 131 and the power supply 20, and the user can also control the power on and off between the second heating wire 132 and the power supply 20. In other words, the user can, as needed, make the first heating wire 131 and the power supply 20 powered on, and the second heating wire 132 and the power supply 20 powered off; or make the second heating wire 132 and the power supply 20 powered on, and the first heating wire 131 and the power supply 20 powered off; or make the first heating wire 131 and the second heating wire 132 both powered on and the power supply 20.

[0059] In one embodiment, see Figure 5 The first heating wire 131 is wound around the outer periphery of the metal oil absorbent 11 , and the second heating wire 132 is wound around the outer periphery of the first heating wire 131 .

[0060] In one embodiment, see Figure 6 The first heating wire 131 is wound around the outer periphery of the metal oil absorbent 11 , the second heating wire 132 is wound around the outer periphery of the metal oil absorbent 11 , and the first heating wire 131 and the second heating wire 132 are arranged in parallel.

[0061] The above are some implementation methods of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications are also considered to be within the scope of protection of the present application.
