Because the heat generating portion of the heat generating base member needs to be completely wrapped between the first heat conducting member and the second heat conducting member, and the first heat conducting member and the second heat conducting member are obtained by sintering and curing the heat conducting ceramic slurry, before the heat conducting ceramic slurry is poured, the heat generating base member needs to be ensured to be shaped, so that the heat conducting ceramic slurry in a fluid state is in a forming mold to completely wrap the heat generating base member, and then the heat conducting ceramic slurry is sintered, cured and shaped.
It should be noted that, because the base member that generates heat is obtained by the combination of two kinds of different materials, in this embodiment, the base member that generates heat includes the portion of generating heat and two electrically conductive pins, two the material of electrically conductive pin with the material that generates heat is different, the portion that generates heat is the great metal portion that generates heat of resistance or the ceramic portion that generates heat, in this embodiment, the portion that generates heat is the great metal portion that generates heat of resistance, specifically is the portion that generates heat such as nickel chromium or iron chromium or ferronickel.
Further, the heat generating portion is a ceramic heat generating portion with a large resistance value, that is, the heat generating portion is made of a conductive heat generating ceramic material, referring to fig. 2, a method for manufacturing a heat generating base member according to an embodiment includes the following steps:

In this embodiment, the first conductive pin and the second conductive pin are positioned in the first mold, so that the first conductive pin and the second conductive pin are positioned relatively, and the heating portion is separated from each other during molding, thereby preventing short circuit from affecting the overall heating performance of the heating portion. Specifically, the first conductive pin may be a positive conductive pin, and the second conductive pin may be a negative conductive pin.
S203: and injecting conductive heating ceramic slurry into the first mold, and molding heating parts respectively connected with the first conductive pin and the second conductive pin.
In this embodiment, a first conductive heating ceramic slurry is injected into the first mold, and heating portions respectively connected to the first conductive pin and the second conductive pin are formed, so that the first conductive pin and the second conductive pin are used for supplying power to the heating portions, and the heating portions are further electrically conductive and heat-generating.
In this embodiment, the heat generating portion is a circular ring structure, the first conductive pin and the second conductive pin are electrically connected to the heat generating portion respectively, and the first conductive pin and the second conductive pin are distributed in axial symmetry with a central axis of the circular ring heat generating portion.
Therefore, the heating part made of the conductive heating ceramic material is fragile, so that the overall mechanical strength is improved by adopting a structure that the first heat conducting part and the second heat conducting part are coated together, and the heating part made of the conductive heating ceramic material can further reduce the content of metal in the electronic cigarette heating mechanism and further improve the heating safety performance.

The one end and the outside air intercommunication of gas pocket 240, the other end of gas pocket 240 is direct and a cigarette intercommunication, so, when heat conduction ceramic member 200 is in the heat conduction state, the outside air of newly entering circulates along gas pocket 240, so, when the outside air of newly entering flows through gas pocket 240, can be heated, and the outside air of newly entering also must only get into by gas pocket 240, this because state first heat-conducting piece with the second heat-conducting piece is locked by the cladding of protective sheath 300, the outside air of newly entering can't flow from clearance between them, has ensured the integral type synchronous heating to the outside air of newly entering, and the heating route is optimized more, does not have the difference in temperature and time difference, and thermal energy efficiency is higher, and energy-conserving effect is better. In order to make the order flow through the gas pocket and the smoke that the newly-entered air that erodes a cigarette can mix a cigarette production smoothly enter into the cigarette holder of electron cigarette in the lump, generally need make cigarette prop up with there is certain clearance in the protective sheath, so, then mean first heat conduction piece 210 and the diameter of second heat conduction piece 220 will be greater than the diameter of cigarette 500, this is because first heat conduction piece and the diameter of second heat conduction piece need with the internal diameter of protective sheath is the same to make the structural stability that both combine higher, so, first heat conduction piece and the better direct contact that the outer fringe of second heat conduction piece then is difficult to produce with a cigarette can cause the loss of partial heat energy, and can't better carry out the sufficient heating to a cigarette, secondly, because a cigarette with there is certain clearance in the protective sheath, so when the electron cigarette is smoked, when the electron cigarette rocks, more or less can make the cigarette be in carry out the displacement in the protective sheath, influence cigarette with the contact effect of first heat-conducting piece and second heat-conducting piece. In order to effectively improve the heat utilization of the cigarette on the first heat-conducting piece and the second heat-conducting piece and reduce the displacement problem of the cigarette on the protective sleeve so as to improve the contact effect of the cigarette and the electronic cigarette heating mechanism, in this embodiment, a positioning area is disposed on an end of the first heat-conducting member away from the second heat-conducting member, and a diameter of the positioning area is adapted to a diameter of a cigarette, so that, when the cigarette is inserted, the head of the cigarette is clamped in the positioning area, firstly, the inner wall of the positioning area can heat the cigarette more fully, contact surface area increase promptly, simultaneously, because the diameter in location district is used for the diameter looks adaptation with cigarette, so the inner wall in location district can carry out fixed action better to cigarette, can alleviate cigarette and be in the displacement problem of protective sheath to improve cigarette with electron cigarette heating mechanism's contact effect. Further, because the diameter of locating area is used for with the diameter looks adaptation of cigarette, so cigarette with space between the locating area overflows that the air can hinder relatively, influence the smoothness nature that the user smoked, in this embodiment, the inner wall of locating area has still been seted up and has been spiraled the air guide channel, it encircles the axial extension of first heat-conducting piece to spiral the air guide channel, the one end that spirals the air guide channel extends to the bottom of locating area, the other end that spirals the air guide channel extends to first heat-conducting piece is kept away from on the terminal surface of the tip of second heat-conducting piece, so, when the air that newly-enters follow the gas pocket flows out the back, most newly-enters the air can be followed spiral the air guide channel and is spiral rising flow, so, can enough ensure the smooth and easy degree when the air overflows to ensure the smoothness that the user smoked, and in the same way, the flow mode that spiral rising can more fully erode the surface of cigarette, take away more smog that volatilize, also make the flow path of air more reasonable, the volume of giving out cigarette is more abundant.
