Referring to fig. 1, a method for preparing an electronic cigarette heating mechanism according to an embodiment includes the following steps:
S101: and casting to obtain the heating base piece by adopting a casting process.
Because the heating part of the heating base member needs to be completely wrapped between the first heat conducting member and the second heat conducting member, and because the first heat conducting member and the second heat conducting member are obtained by sintering and solidifying the heat conducting ceramic slurry, before the heat conducting ceramic slurry is poured, the heating base member needs to be ensured to be shaped, so that the heat conducting ceramic slurry in a fluid state is in a forming die to completely wrap the heating base member, and then sintering, solidifying and shaping are performed.
It should be noted that, because the heating base member is obtained by combining two different materials, in this embodiment, the heating base member includes a heating portion and two conductive pins, the materials of the two conductive pins are different from those of the heating portion, the heating portion is a metal heating portion or a ceramic heating portion with a larger resistance value, and in this embodiment, the heating portion is a metal heating portion with a larger resistance value, specifically, a heating portion such as nickel-chromium, iron-chromium, or nickel-iron.
Further, the heating part is a ceramic heating part with a larger resistance value, that is, the heating part is made of a conductive heating ceramic material, referring to fig. 2, the preparation method of the heating base member in an embodiment includes the following steps:
s201: and casting to obtain the first conductive pin and the second conductive pin respectively by adopting a casting process.
The first conductive pin and the second conductive pin are obtained by casting through the casting process preferentially, and can be better covered by the heating part.
S202: the first conductive pin and the second conductive pin are positioned within a first mold.
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 are separated from each other when the heating part is formed subsequently, so that the integral heating performance of the heating part is prevented from being affected due to short circuit. 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 the conductive heating ceramic slurry into the first die, and forming heating parts respectively connected with the first conductive pins and the second conductive pins.
In this embodiment, the first conductive heating ceramic paste is injected into the first mold, and heating portions respectively connected to the first conductive pins and the second conductive pins are formed, so that the first conductive pins and the second conductive pins are used for supplying power to the heating portions, and the heating portions are made to generate heat in a conductive manner.
In this embodiment, the heat generating portion is a ring-shaped structure, the first conductive pins and the second conductive pins are respectively electrically connected with the heat generating portion, and the first conductive pins and the second conductive pins are axially symmetrically distributed along the central axis of the ring-shaped heat generating portion.
Therefore, the structure that the first heat conducting piece and the second heat conducting piece are coated together is needed to improve the whole mechanical strength, and secondly, the heating part is made of the conductive heating ceramic material, so that the metal content in the heating mechanism of the electronic cigarette can be further reduced, and the heating safety performance is further improved.
S102: and placing the heating base piece in a forming die.
Through the positioning of the heating base piece in the forming die in advance, when the heat-conducting ceramic slurry is poured in the follow-up process, the position of the heating base piece in the heat-conducting ceramic slurry can be controlled, and the heat-conducting ceramic slurry can be correspondingly formed into an expected structure after being sintered.

Further, the temperature of the baking and shaping operation is 150-200 ℃. So, can be more convenient for carry out subsequent repair operation, further play better design effect, simultaneously, also can not excessive curing, lead to with first heat-conducting piece with when the second heat-conducting piece carries out sintering solidification, both sintering fixed degree is too big, influences the wholeness of heat conduction effect.
S105: and performing trimming operation on the end face of the first heat conduction piece.
In this embodiment, the trimming operation is a polishing trimming operation, so, the heating part of the heating base member is better wrapped in the wrapping area formed between the first heat conducting member and the second heat conducting member, and in the actual pouring process, tiny bubbles are less likely to be generated around the heating part of the heating base member, so that the internal structure of the heat conducting ceramic member formed after the connection of the first heat conducting member and the second heat conducting member is denser, more stable heat conducting effect, and also can be in closer contact with the heating part of the heating base member, the first conductive pins and the second conductive pins, thereby ensuring better heat conducting effect.

In this embodiment, the materials of the first heat-conducting ceramic slurry and the second heat-conducting ceramic slurry are the same, so as to better ensure the consistency of the heat-conducting effect; further, the heat conductive ceramic slurry is mainly oxide, nitride, carbide, boride and the like, such as AlN, beO, si N4, siC, BN and the like.
S107: and sintering and curing the first heat conduction piece and the second heat conduction piece to obtain the heating mechanism of the electronic cigarette.
In this embodiment, in the sintering and curing process of the first heat conducting member and the second heat conducting member, the sintering and curing temperature is 500 ℃ to 1800 ℃, so that the first heat conducting member and the second heat conducting member can be better sintered and cured, and the consistency of the heat conducting effects of the first heat conducting member and the second heat conducting member can be better ensured.
In this embodiment, after the operation of sintering solidification treatment is performed on the first heat conducting piece and the second heat conducting piece, cooling shaping is performed, so that the heat conducting ceramic body integrally connected with the first heat conducting piece and the second heat conducting piece is obtained, and the protective sleeve is sleeved outside the heat conducting ceramic body, so that the first heat conducting piece and the heat of the second heat conducting piece can be better locked through the protective sleeve, and when a cigarette is inserted into the protective sleeve, the cigarette is heated more intensively, and a better positioning and placing effect is easy to be achieved on the cigarette.
In this embodiment, the portion that generates heat of base member that generates heat is located first heat-conducting member with the middle part position department of second heat-conducting member, so, make the outer terminal surface of first heat-conducting member with the distance of portion that generates heat and the outer terminal surface of second heat-conducting member with the distance phase difference of portion that heats less, even be zero, and then make the temperature on electron cigarette heating mechanism surface more even, solved the relatively poor problem of the heating effect of electron cigarette.

In order to make the smoke generated by mixing the air holes sequentially flowing through the air holes and the fresh air flowing through the cigarettes smoothly enter the cigarette holder of the electronic cigarette, a certain gap is generally required between the cigarettes and the protective sleeve, which means that the diameters of the first heat conducting piece 210 and the second heat conducting piece 220 are larger than the diameter of the cigarette 500, because the diameters of the first heat conducting piece and the second heat conducting piece are required to be the same as the inner diameter of the protective sleeve, so that the combined structural stability of the two is higher, and if the outer edges of the first heat conducting piece and the second heat conducting piece are difficult to be in good direct contact with the cigarettes, the loss of partial heat energy can be caused, and the cigarette can not be heated well, and secondly, because the cigarette and the protective sleeve have a certain clearance, when the electronic cigarette is sucked, the electronic cigarette can more or less make the cigarette shift in the protective sleeve when rocking, and the contact effect of the cigarette with the first heat conducting piece and the second heat conducting piece is affected. In order to more effectively improve the heat energy utilization of the first heat conducting piece and the second heat conducting piece by the cigarette 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 the embodiment, the end part of the first heat conducting piece far away from the second heat conducting piece is provided with a positioning area, the diameter of the positioning area is used for being matched with the diameter of the 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, namely the contact surface area is increased, and meanwhile, because the diameter of the positioning area is used for being matched with the diameter of the cigarette, the inner wall of the positioning area can better fix the cigarettes, so that the displacement problem of the cigarettes on the protective sleeve can be reduced, and the contact effect of the cigarettes and the heating mechanism of the electronic cigarette is improved. Further, since the diameter of the positioning area is adapted to the diameter of the cigarette, the air flowing through the gap between the cigarette and the positioning area is relatively hindered, which affects the smoothness of the user's intake, in this embodiment, the inner wall of the positioning area is further provided with a spiral air guide channel, the spiral air guide channel extends around the axial direction of the first heat conducting member, one end of the spiral air guide channel extends to the bottom of the positioning area, the other end of the spiral air guide channel extends to the end surface of the first heat conducting member away from the end of the second heat conducting member, so that when new air flows out from the air hole, most of the new air flows along the spiral air guide channel in a spiral rising manner, so, can enough ensure the smoothness when air overflows to ensure the smoothness nature that the user smoked, the same reason, the flow mode that the spiral risees can wash away the surface of cigarette more fully, takes away more smog that volatilizees, also makes the flow path of air more reasonable, and it is full abundant to go out the cigarette volume.
