Specific implementation manners

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Embodiment 1

[0028] Please refer to Figure 1-2 As shown, a ceramic atomization core in this embodiment includes a ceramic body 1, a heating element 2 arranged at the bottom of the ceramic body 1, and a lead wire 3 connected to the heating element 2. The heating element 2 is a heating wire or a heating sheet. The ceramic body 1 includes a hollow matrix 11 and an upwardly protruding and hollow airway part 12 arranged at the center of the matrix 11. There is an annular downwardly concave groove part 13 between the matrix 11 and the airway part 12.

[0029] With the above structure, compared with traditional products, the volume of the ceramic body is generally reduced, facilitating the rapid heating and atomization of the atomization core during operation; the base body 11 and the protruding airway part 12 are integrally in a stepped structure, which can conveniently connect and install the base body 11 and the airway part 12 with other atomization components respectively to form a stable double-support and double-seal structure, enhancing the reliability and tightness of the product structure. At the same time, it enables the oil inlet (through the base body 11) and the air outlet (through the airway part 12) to occur at different levels, preventing e-liquid from entering the airway part and reducing the occurrence of e-liquid splashing; the base body 11, the airway part 12, and the groove part 13 are arranged in layers, which is beneficial to the direct pressing force acceptance of each part during the ceramic pressing and forming process. The overall ceramic pressing force acceptance is uniform and the structure is firm; the protruding hollow design of the airway part 12 enables the airway part to be directly installed and connected to the airflow channel of the atomizer. When the atomization core works, the atomized aerosol generated preferentially enters the airway part, and the atomized gas enters the mouthpiece approximately vertically, with smooth airflow; the groove part 13 can play a role in caching e-liquid. When the atomization core is heated, the penetration rate of e-liquid in the ceramic base body increases, and the e-liquid penetrating into the heating element 2 is atomized. The newly entered e-liquid in the atomization core is further compensated into the groove part 13 by gravity, forming a uniform and smooth e-liquid supply.

[0030] Preferably, the inner diameter of the airway part can be set to be greater than or equal to 3 mm. Among them, a more smooth ventilation effect can be obtained with 3 mm - 5 mm, reducing the generation of condensate.

[0031] Preferably, the base body 11 of this embodiment is set in a circular plate shape, and the heating element 2 is set in an annular structure corresponding to the shape of the base body 11. The annularly distributed heating elements are further beneficial to maintaining heating balance. Embodiment 2

[0032] As Figure 3 shown, on the basis of Embodiment 1, the airway part 12 of the atomization core in this embodiment includes a first section part 121 and a second section part 122. The horizontal height of the first section part 121 is higher than the horizontal height of the base body 11. The second section part 122 is arranged directly above the first section part 121. A first platform surface 123 is provided between the first section part 121 and the second section part 122. The cross-sectional area of the second section part 122 is smaller than the cross-sectional area of the first section part 121. The first section part and the second section part have hollow channels with the same inner diameter.

[0033] With the above structure, when installing the atomization core with other atomization components, the first platform surface 123 in the middle position of the atomization core can play a further supporting role, is not easily collapsed, and forms a more stable connection; at the same time, it provides space for setting the groove part 13 as large as possible, and can expand the e-liquid caching capacity of the atomization core assembly. The first section part 121 of this embodiment is set as a smaller plane, which can further reduce the volume of the ceramic body and improve the heating efficiency. Embodiment 3

[0034] As Figure 4 shown, this embodiment is an atomization assembly including the atomization core described in Embodiment 2.

[0035] An atomization assembly of this embodiment includes a silica gel sleeve 6 and the atomization core described in Embodiment 2. The silica gel sleeve 6 is sleeved on the outer walls of the atomization core base 11 and the airway part 12. The silica gel sleeve has a first vertical section 61 that wraps the outer wall of the base 11 and a second vertical section 62 that wraps the outer wall of the airway part 12. The top of the first vertical section 61 is higher than the top of the disc base 11; there is a second platform 63 between the first vertical section 61 and the second vertical section 62. The bottom part of the second platform 63 is supported on the first platform surface 123. More than 2 evenly distributed liquid guide holes are provided on the second platform 63, and the liquid guide holes are communicated with the groove part 13 of the atomization core.

[0036] Due to the above structure, the inner wall of the silica gel sleeve 6 of this embodiment is respectively attached to the outer wall of the base 11, the outer wall of the airway part 12, and the surface of the first platform surface 123, which can play a comprehensive sealing role. At the same time, the airway part 12 of the atomization core can be connected to the main air flow channel of the atomizer through the top of the silica gel sleeve 6, thus forming a complete air flow channel; by providing a plurality of liquid guide holes on the second platform 63, the e-liquid can uniformly enter the groove part 13 through the liquid guide holes. The top of the first vertical section 61 exceeds the top of the disc base 11, which can increase the volume of the atomization core oil storage transition bin composed of the groove part 13 and the airway part 12, thereby forming a more uniform e-liquid conveying channel; the silica gel sleeve 6 also plays a role in protecting and supporting the atomization core.

[0037] The atomization assembly of this embodiment can be widely applied to other types of atomizers in addition to being used in common rod-shaped atomizers. Embodiment 4

[0038] As Figure 5-6 shown, this embodiment provides an atomizer, which includes an oil cup 4, an airway tube 5, and the atomization assembly described in Embodiment 3. The oil cup 4 and the airway tube 5 are made of glass material and are integrally formed. The bottom of the oil cup 4 is connected with a metal tube 41 containing internal threads by an adhesive method.

[0039] The atomizer of this embodiment further includes an atomization core mounting seat 7, a silica gel seat 8, and a base 9. The atomization core mounting seat 7 is used to mount the atomization assembly described in Embodiment 3. The silica gel seat 8 is arranged below the atomization core. The silica gel seat 8 is installed in the base 9. The atomization core mounting seat 7 and the base 9 are fixed together by a tight fit or a snap connection.

[0040] There are more than 2 hollow airway protrusions 81 and 2 wire holes provided on the silica gel base 8. The provision of the airway protrusions is conducive to uniform air intake, and the provision of the wire holes is conducive to improving the sealing performance between the oil cup and the atomizing core, thereby preventing e-liquid leakage.

[0041] Preferably, it further includes an absorbent cotton 10. The absorbent cotton 10 is installed in the silica gel base 8. The absorbent cotton 10 is provided with an opening for installing the airway protrusion 81 and a wire passing hole 101 through which the wire can pass. The function of the absorbent cotton 10 is to adsorb the possible condensate or other e-liquid flowing out along the wire, preventing the e-liquid from damaging the operation of the electronic cigarette.

[0042] Preferably, the oil cup 4 is cylindrical, the atomizing core mounting seat 7 and the base 9 are made of metal. The atomizing core mounting seat is provided with an external thread 71 corresponding to the internal thread 411 of the metal tube 41. An insulating sleeve 20 and a hollow electrode member 21 are sequentially arranged below the base 9. The two leads of the atomizing core are insulated by the insulating sleeve 20. One of the leads is arranged inside the electrode member 21, and the other lead is clamped on the insulating sleeve 20 and connected to the base 9. By adopting the above structure, the electrode cost of the atomizer can be reduced.
