The base electrode assembly 13 is provided with an electrical connector for electrical connection with a host. The electrical connection members may be two positive and negative electrical connection members, but when the atomization cap is used as the negative electrode, only one positive electrical connection member is needed, and of course, portions of the positive contact member 123 and the negative contact member 122 may be used as the electrical connection members.

In one embodiment, the base electrode assembly 13 includes an insulating holder 132, a positive electrode holder 131, and a negative electrode holder 133; the positive electrode holder 131 is mounted on the insulating holder 132 and is in contact with the positive electrode contact 123, and the negative electrode holder 133 is fixed to the bottom of the atomizing hood 11. The positive electrode holder 131 includes an insertion part 1311, the negative electrode holder 133 is provided at a middle portion thereof with a mounting hole for receiving the insertion part 1311, and a bottom surface area of the insertion part 1311 is flush with a bottom surface area of the negative electrode holder 133.

In the present embodiment, the positive electrode holder 131 and the negative electrode holder 133 are used as the positive electrode electrical connector and the negative electrode electrical connector electrically connected to the host machine.

In this embodiment, the insulating base 132 is made of a plastic material, and has insulating performance, a first hole site and a second hole site are provided on the insulating base 132, during assembly, the first hole site corresponds to the connection hole site of the positive contact 123, and the positive base 131 is also provided with a hole site corresponding to the connection hole site of the positive contact 123, during assembly, the positive base 131 is disposed on the insulating base 132, and the positive base 131, the insulating base 132, the positive contact 123 and the insulating part 124 are fixed on the inner side wall of the atomizing cover 11 through the second screw 127.

In some embodiments, the first electrical contact region and the second electrical contact region are located at opposite ends of the ceramic heating element in the length direction, and are convenient for contact fitting with the positive contact and the negative contact.

In one embodiment, the longitudinal direction of the ceramic heat-generating body 121 is arranged parallel to or inclined to the axial direction of the atomizing hood 11. The inclined arrangement mode can narrow the airflow channel between the ceramic heating element 121 and the atomizing cover 11, so as to form the aerosol gathering effect. The diameter of the ceramic atomizing core 1 can be made smaller by adopting the parallel arrangement mode. Of course, it is also possible to provide that the length direction of the ceramic heating element 121 is arranged perpendicularly to the axial direction of the atomizing cover 11, i.e., the ceramic heating element 121 is placed laterally, enabling the length of the ceramic atomizing core 1 to be made shorter.

In this embodiment, a heating element 12 is disposed in the atomizing cover 11, a ceramic heating element 121 of the heating element 12 is rectangular and vertically disposed in the atomizing cover 11, and the ceramic heating element 121 is made by a coating process and can support power output of 15-40W.

Specifically, the ceramic heating element 121 includes a porous ceramic substrate and a heating element, the heating element may be a heating film or a heating wire, or a heating network, preferably, the heating element is a heating film, and the heating element may be disposed on the surface of the porous ceramic substrate (printing or coating process may be used), or may be embedded in the porous ceramic substrate; when embedded, the first and second electrical contact regions, in particular the electrode membrane layers, are still provided on the surface of the porous ceramic substrate. After the assembly is finished, one surface of the heating part, which is exposed out of the airflow channel, is an atomization surface, and the first electric contact area and the second electric contact area are in contact with the heating part to form electric connection; the surface on which the heat generating member is placed is exposed in the air flow passage 16.

In this embodiment, the first electrical contact area and the second electrical contact area are at the position of the surface where the heat generating member is located. In other embodiments, the first electrical contact area and the second electrical contact area are disposed on a sidewall of the surface on which the heat generating member is disposed, and the first electrical contact area and the second electrical contact area may be on the same sidewall or different side arms. The first electric contact area and the second electric contact area are provided on the side wall so that the positive contact 123 and the negative contact 122 are not laminated to the surface of the ceramic heat-generating body 121, whereby the obstruction of the air passage 16 by the positive contact 123 and the negative contact 122 can be reduced, which is advantageous in that the diameter of the ceramic atomizing core can be made smaller.

In the present embodiment, the negative contact 122 is located above the positive contact 123, and the negative contact 122 is directly fixed on the inner side wall of the atomizing cover 11 by a first screw 126 (a connection structure such as a snap or a pin may also be adopted). The positive contact 123 is fixed on the inner side wall of the atomizing cover 11 by a second screw 127 (a connection structure such as a snap, a pin, etc. may also be adopted).

Moreover, the first screw 126 and the second screw 127 do not directly contact with the ceramic heating element 121, thereby preventing abrasion of the ceramic heating element 121 caused by screwing when mounting.

In this embodiment, the atomization cover 11 is made of a metal material, an insulating member 124 is installed between the positive contact 123 and the inner sidewall of the atomization cover 11, and the insulating member 124 has an annular structure. Since the atomizing cover 11 is made of a metal material and is used as a negative electrode, the insulating member 12 needs to be attached between the positive contact 123 and the inner wall of the atomizing cover 11 so that the positive contact 123 and the atomizing cover 11 are insulated from each other. Of course, in other embodiments, the positive contact 123 and the atomization cap 11 may be in a floating state, for example, the positive contact 123 is fixedly connected with the negative contact 122 through the insulating member 124, and is not directly fixedly connected with the atomization cap 11. If the atomizing cover is made of a metal material and is not used as the negative electrode, it is necessary to ensure that the negative electrode contact 122 is insulated from the atomizing cover 11.

In one embodiment, as shown in FIG. 5, the ceramic heating element 121 is provided with an oil guide groove 1211 communicating with the oil inlet hole 111.

In one embodiment, as shown in fig. 4 and 5, the negative contact 122 includes a first body 1221, and a first lug structure 1222 extending from the first body 1221; at least a partial region of the first lug structure 1222 is in contact with the first electrical contact region. The positive contact 123 includes a second body 1231, and a second lug structure 1232 extending from the second body 1231; at least a partial region of the second lug structure 1232 is in contact with the second electrical contact region. Since the first and second lug structures 1222, 1232 are thinner, the impact on the airflow passage 16 can be reduced.

In the present embodiment, the first lug structure 1222 is recessed, and when the first lug structure 1222 is connected to the first electrical contact area in a contact manner, two baffles extending from the back of the first lug structure 1222 can block condensate. The second lug structure 1232 is in the shape of a thin plate, directly in contact with the second electrical contact area.

By adopting the ceramic heating body, compared with a cotton core, atomized aerosol is finer and smoother, and is safer, durable and attenuation-resistant compared with the cotton core after high-temperature sintering, so that the market blank that the medium-high power ceramic atomizing core can only select the cotton core but does not have other choices is filled, and new choices and experiences are provided for users.
