[0024] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0025] like Figure 1 As shown, it is an overall structural diagram of an atomizer core assembly provided by an embodiment of the present invention, wherein the atomizer core assembly comprises a base 2, heat insulating sponge 8, oil storage sponge 7 and an electric heating plate;

[0026] The base 2 is set in a disc shape, the bottom surface of the base 2 is provided with an air inlet 10, the top surface of the base 2 is provided with an air outlet 11, and the air inlet 10 and the air outlet 11 are connected through a channel 9 set inside the base 2;

[0027] The heat-insulating sponge 8 is disposed on the top surface of the base 2 and is in the shape of a disk with a central opening;

[0028] The oil storage sponge 7 is arranged on the top of the heat insulation sponge 8 and is a columnar structure with a hole in the middle, and the middle hole is connected with the central hole of the heat insulation sponge 8 and the air outlet 11 of the base 2;

[0029] The electric heating plate is disposed in the channel 9 and includes a heating portion 4 having a top plane, an electrode 3 connected to the heating portion 4, and a fixing portion 5 covering the periphery of the heating portion 4 and exposing the top plane.

[0030] In this embodiment, if Figure 2 As shown, the base 2 can be made of silicone; the air inlet 10 is located at a non-center position on the bottom surface of the base 2, and the air inlet 10 is set to be circular, and the air outlet 11 is set at the center position of the top surface of the base 2, and is set to be circular. The channel 9 is opened inside the base 2 along the radial direction of the disk, and the cross section can be set to be circular.

[0031] In this embodiment, the heat-insulating sponge 8 and the oil-storing sponge 7 are made of sponges with different densities or pore sizes. Under the same volume, the oil-storing sponge 7 can absorb more smoke oil and is the main structure of the atomizer core to store smoke oil. The heat-insulating sponge 8 is a structure that is in direct contact with the heating plate. The smoke oil in the oil-storing sponge 7 can enter the heat-insulating sponge 8, and then be heated and evaporated by the electric heating plate. In this embodiment, through holes are opened in the middle of the heat-insulating sponge 8 and the oil-storing sponge 7, and the through holes of the two are interconnected. The smoke oil heated and evaporated by the electric heating plate enters the central hole of the heat-insulating sponge 8 from the channel 9 in the base 2 through the air outlet 11, and then enters the middle hole of the oil-storing sponge 7.

[0032] In this embodiment, if Figure 3 , 4As shown, the heating part 4 has a top plane, which is circular as a whole, and the two sides of the top plane are connected to the electrode 3, which is located on the side of the top plane, and the electrode 3 is perpendicular to the top plane as a whole. Furthermore, the lower surface edge of the top plane is provided with a toothed structure perpendicular to the top plane, which can increase the heat transfer area and make the fixing part 5 more firm and reliable when it is wrapped on the heating part 4.

[0033] In this embodiment, further, two through holes are provided on the base 2, and the two through holes can allow the electrodes 3 to pass through; after the electric heating plate is installed and fixed, it is located in the channel 9 of the base 2, and its electrode 3 passes through the bottom surface of the base 2. In this embodiment, the fixing part 5 can be formed by ceramic slurry.

[0034] The atomizer core assembly provided by the present invention includes an electric heating plate, wherein the electric heating plate is composed of a heating portion 4 with a top plane, an electrode 3 and a fixing portion 5, wherein the fixing portion 5 is wrapped around the outer periphery of the heating portion 4 and exposes the top plane so as to contact with the heat-insulating sponge 8 to heat and evaporate the tobacco oil to obtain smoke. At the same time, a base 2 with an internal channel 9 is provided, and the electric heating plate is arranged in the base 2, which can facilitate the fixation of the electric heating plate, and the installation position of the electric heating plate on the base 2 matches the shape of the electric heating plate, which can further prevent the deformation of the electric heating plate. The atomizer core assembly provided by the present invention solves the problem that the existing electric heating plate is easily deformed during installation, so that the heating surface of the electric heating plate is fully in contact with the tobacco oil, preventing overheating and stabilizing the atomization process.

[0035] like Figure 5 As shown, in one embodiment of the present invention, in the working state, the top plane contacts the bottom surface of the thermal insulation sponge 8.

[0036] In this embodiment, the working state here specifically refers to the process in which the electric heating plate heats up and evaporates the tobacco oil. At this time, the tobacco oil on the heat-insulating sponge 8 seeps onto the top surface of the electric heating plate and is evaporated into smoke.

[0037] like Figure 5 As shown, in one embodiment of the present invention, the atomizer core assembly further includes an air pipe 6 disposed on the top surface of the base 2 , the air pipe 6 is connected to the air outlet 11 of the base 2 , and passes through the central hole of the heat insulating sponge 8 and the middle hole of the oil storage sponge 7 .

[0038] In this embodiment, the air pipe 6 is provided to prevent the evaporated smoke from entering the oil storage sponge 7 or the heat-insulating sponge 8 again, thereby isolating the smoke oil before and after evaporation; at the same time, the air pipe 6 is an integrated structure, passing through the oil storage sponge 7 and the heat-insulating sponge 8 at the same time, and can fix the oil storage sponge 7 and the heat-insulating sponge 8.

[0039] like Figure 5As shown, in one embodiment of the present invention, the atomizer core assembly further includes an oil tank tube 1, the oil tank tube 1 is configured as a cylindrical tube, the base 2 is sleeved on the bottom of the oil tank tube 1, and a sealing rubber ring is provided on the contact surface between the base 2 and the oil tank tube 1;

[0040] The inner diameter of the oil tank pipe 1 is adapted to the outer diameters of the heat insulating sponge 8 and the oil storage sponge 7 , and the heat insulating sponge 8 and the oil storage sponge 7 are enclosed therein.

[0041] In this embodiment, the oil tank tube 1 is provided to prevent the oil in the oil storage sponge 7 and the heat insulation sponge 8 from seeping into other structures from the side, while also reducing the volatilization of the oil, thereby playing the role of sealing the atomizer core; the oil tank tube 1 and the base 2 together form the overall outer layer of the atomizer core, protecting the structure containing the oil.

[0042] like Figure 6 , 7 As shown, in one embodiment of the present invention, the atomizer core assembly further comprises a heat insulating sponge 8 driving device, and the heat insulating sponge 8 driving device is used to drive the heat insulating sponge 8 to rotate during inhalation to change the contact position between the heat insulating sponge 8 and the electric heating plate.

[0043] In this embodiment, by providing a driving device for the thermal insulation sponge 8, the thermal insulation sponge 8 can be driven during inhalation, thereby changing the contact position between the thermal insulation sponge 8 and the electric heating plate, preventing the same position of the thermal insulation sponge 8 from being heated for a long time and causing burning and blackening, thereby destroying the flatness of the contact surface between the thermal insulation sponge 8 and the electric heating plate, making the evaporation process unreliable and reducing the atomization efficiency.

[0044] like Figure 6 , 7 As shown, in one embodiment of the present invention, the heat insulation sponge 8 driving device includes a spacer 12, a transmission mechanism and a return spring;

[0045] The partition 12 is arranged in the channel 9, covering the connection between the air inlet 10 and the channel 9, and a plurality of guide rods 18 are arranged at the lower part of the partition 12 to fit the inner wall of the air inlet 10, and a rack is arranged on one of the guide rods 18;

[0046] The transmission mechanism is arranged inside the base 2, including a first gear 17 meshing with the rack, the first gear 17 is arranged on the first rotating shaft, the first rotating shaft is rotatably connected to the base 2, and a second gear 13 is also arranged on the first rotating shaft, the second gear 13 is a bevel gear, and the second gear 13 is meshed with a third gear 16; the third gear 16 is a bevel gear, the third gear 16 is arranged on the second rotating shaft, the second rotating shaft is rotatably connected to the base 2, the first rotating shaft and the second rotating shaft are both parallel to the top surface of the base 2, and the first rotating shaft and the second rotating shaft are perpendicular to each other; a fourth gear 15 is also arranged on the second rotating shaft, the fourth gear teeth are meshed with the fifth gear 14, the fifth gear 14 is arranged on the third rotating shaft, the third rotating shaft is rotatably connected to the base 2, and the fifth gear 14 is meshed with the annular rack located on the outer edge of the bottom surface of the thermal insulation sponge 8;

[0047] One end of the return spring is connected to the lower surface of the spacer 12 , and the other end of the return spring is connected to the bottom surface of the base 2 after passing through the air inlet 10 .

[0048] In this embodiment, through the above-mentioned arrangement, when inhaling, the air pressure in the channel 9 decreases, the diaphragm 12 pulls the reset spring to open, the diaphragm 12 moves upward, and the gear drives the first gear 17 to rotate, and the second gear 13 coaxially arranged with the first gear 17 drives the third gear 16 to rotate; the fourth gear 15 coaxial with the third gear 16 drives the fifth gear 14 to rotate, and the fifth gear 14 engages with the rack on the outer edge of the bottom surface of the thermal insulation sponge 8, thereby driving the thermal insulation sponge 8 to rotate; in one embodiment, the thermal insulation sponge 8 rotates with the air pipe 6 as the axis, and the contact surface between the thermal insulation sponge 8 and the electric heating plate is changed by rotation, so that the entire bottom surface of the thermal insulation sponge 8 is fully utilized.

[0049] like Figure 6 , 7 As shown, in one embodiment of the present invention, the atomizer core assembly further includes a heat insulating sponge 8 separation mechanism, and the heat insulating sponge 8 separation mechanism is used to separate the heat insulating sponge 8 from the electric heating plate in a non-heating state.

[0050] In this embodiment, in the non-working state, that is, when the electric heating plate is not in the state of heating and evaporating the smoke oil, the heat-insulating sponge 8 is separated from the electric heating plate and is in contact with the oil storage sponge 7 at this time, absorbing the smoke oil from the oil storage sponge 7; while in operation, the heat-insulating sponge 8 moves downward to contact the electric heating plate and is separated from the oil storage sponge 7, thereby achieving isolation from the oil storage sponge 7 during the heating and evaporation process, and can effectively reduce the heat transferred to the oil storage sponge 7 through the heat-insulating sponge 8. This process is achieved through the separation mechanism of the heat-insulating sponge 8.

[0051] like Figure 6 , 7As shown, in one embodiment of the present invention, the thermal insulation sponge 8 separation mechanism includes a plurality of top balls 20 arranged on the top surface of the base 2, the top balls are located in positioning holes 19 opened on the top surface of the base 2, and a spring is arranged in the positioning hole 19.

[0052] In the present embodiment, the thermal insulation cotton separation mechanism is configured in the form of a spring top bead 20, and further, the positioning hole 19 is connected to the channel 9; when the suction pressure in the channel 9 decreases, the thermal insulation cotton 8 squeezes the spring downward, and the thermal insulation cotton 8 moving downward contacts the top of the electric heating plate; as the pressure further increases, the diaphragm 12 opens, and during the heating and atomization process, the thermal insulation cotton rotates at a small angle under the action of the thermal insulation cotton 8 driving device; when the suction stops, the pressure in the channel 9 is restored, and under the action of the spring and the top bead 20, the thermal insulation cotton 8 moves downward and disengages from the top surface of the electric heating plate and the fifth gear 14, and at this time, the thermal insulation cotton 8 driving device is reset under the action of the reset spring, completing a cycle.

[0053] In this embodiment, the top bead 20 is set to be ellipsoidal and is pressed against the bottom of the insulation sponge 8 under the action of the spring. When the pressure decreases and the insulation sponge 8 moves downward, the top bead 20 presses on the entrance of the positioning hole 19, separating the insulation sponge 8 from the channel 9, preventing the unheated and evaporated tobacco oil from being sucked in through the positioning hole 19 and the channel 9.

[0055] The electronic cigarette itself; and

[0056] As described in the embodiment of the present invention, the atomizer core assembly is assembled in the electronic cigarette body and is detachably connected to the electronic cigarette body.
