Compared with the prior art, the utility model discloses at least, following advantage has:

1. because the electronic cigarette heater has a double heating function, namely one heating mode is direct contact heating of the heater to cigarettes, namely conduction heating; another kind of heating methods is the heating of air brush formula, and the user is in the smoking in-process promptly, and the outside air that newly enters can flow through the heater in advance, and the heater heats the air that flows through, and this heated air flows through cigarette again, erodees a cigarette, plays the heating effect to a cigarette to take out smog to the cigarette holder, supply the user to smoke. Aiming at the heat conducting ceramic with a cylindrical structure, a metal heating element is generally integrally attached to the inner surface of the heat conducting ceramic in a patch or circuit printing mode, newly-entered air can simultaneously flow through the inner surface and the outer surface of the heat conducting ceramic and finally is collected into a cigarette holder together with smoke, namely, the newly-entered air can flow through the inner cylinder surface and the outer cylinder surface of the cylindrical heat conducting ceramic, the inner surface of the heat conducting ceramic is higher than the outer surface, so that the newly-entered air is divided into two parts and has temperature difference, the heat energy is not favorably and effectively utilized, and the energy-saving effect is poor. The heat conduction ceramic body of present case is because endocyst heating portion, the whole heat conduction effect of heat conduction ceramic body is fairly even and stable, and the air that the external new income can only circulate along air guide channel, so, when the air guide channel is flowed through to the new income air current of external, can be heated, and the air of external new income must also can only get into by air guide channel, this is because heat conduction ceramic body is by heat insulator cladding locking, the air of external new income can't flow from clearance between them, the integral type synchronous heating to the air of external new income has been ensured, the heating path is optimized more, do not have difference in temperature and time difference, thermal energy efficiency is higher, energy-conserving effect is better.

2.

3. Because the heating element is integrally attached to the surface of the heat-conducting ceramic in a patch or circuit printing mode, when the metal heating element generates heat by itself in an electric conduction mode, the heating path of the metal heating element is unreasonable, because the metal heating element has two heating regions and two heating time differences, for the two heating regions, the temperature of a sintering layer right above the metal heating element is certainly greatly higher than that of the rest sintering layers because the heat of the rest sintering layers needs to be transferred through the heat-conducting ceramic, for the two heating time differences, the temperature of the sintering layer right above the metal heating element is certainly the fastest and is directly transferred by the metal heating element, but because the heat of the rest sintering layers needs to be transferred through the heat-conducting ceramic, the problem of time lag exists. Therefore, a problem of unreasonable heating paths may be caused. However, the present case pours into the first ceramic thick liquids and the second ceramic thick liquids in the mould into respectively at the both ends of mould, when the encapsulating, can ensure that mould both ends injection volume is unanimous, makes the terminal surface of first heat-conducting piece and the distance of metal heating member and the terminal surface of second heat-conducting piece and the distance of metal heating member differ less, is zero even, and then makes the temperature on electron cigarette heater surface more even, has optimized the bulk heating route, has solved the relatively poor problem of heating effect of electron cigarette.

and injecting the second ceramic slurry into the second heat-conducting piece molding area of the third mold through a pouring port of the third mold so as to connect the second heat-conducting piece with the second semi-finished product.

S500: and curing the second heat-conducting piece to enable the second heat-conducting piece to be connected with the first heat-conducting piece to form a heat-conducting ceramic body, and further enabling the heat-conducting ceramic body to be coated outside the metal heating element to obtain the electronic cigarette heater.

In this embodiment, a method for manufacturing an electronic cigarette heater includes: injecting a first ceramic slurry into the mold to form a first heat conducting piece; curing the first heat-conducting member; forming a metal heating element in the mold, and connecting the metal heating element with the first heat-conducting member; injecting a second ceramic slurry into the mold to form a second heat-conducting member connected with the metal heating member; and curing the second heat-conducting piece to connect the second heat-conducting piece and the first heat-conducting piece to form a heat-conducting ceramic body, and further coating the heat-conducting ceramic body outside the metal heating element to obtain the electronic cigarette heater, wherein the obtained electronic cigarette heater is the electronic cigarette heater in any embodiment.

In one embodiment, an electronic cigarette heater is manufactured by the method for manufacturing an electronic cigarette heater according to any one of the above embodiments, so that the electronic cigarette heater has better heating performance.

Compared with the prior art, the scheme has the following advantages at least:

1. because the electronic cigarette heater has a double heating function, namely one heating mode is direct contact heating of the heater to cigarettes, namely conduction heating; another kind of heating methods is the heating of air brush formula, and the user is in the smoking in-process promptly, and the outside air that newly enters can flow through the heater in advance, and the heater heats the air that flows through, and this heated air flows through cigarette again, erodees a cigarette, plays the heating effect to a cigarette to take out smog to the cigarette holder, supply the user to smoke. Aiming at the heat conducting ceramic with a cylindrical structure, a metal heating element is generally integrally attached to the inner surface of the heat conducting ceramic in a patch or circuit printing mode, newly-entered air can simultaneously flow through the inner surface and the outer surface of the heat conducting ceramic and finally is collected into a cigarette holder together with smoke, namely, the newly-entered air can flow through the inner cylinder surface and the outer cylinder surface of the cylindrical heat conducting ceramic, the inner surface of the heat conducting ceramic is higher than the outer surface, so that the newly-entered air is divided into two parts and has temperature difference, the heat energy is not favorably and effectively utilized, and the energy-saving effect is poor. The heat conduction ceramic body 200 of present case is because endocyst heating portion 110, the whole heat conduction effect of heat conduction ceramic body 200 is fairly even and stable, and the air that the external new income can only circulate along air guide channel 240, so, when the air current of the new income of external world flows through air guide channel 240, can be heated, and the air of external new income must also can only get into by air guide channel 240, this is because heat conduction ceramic body 200 is locked by thermal-insulated piece 300 cladding, the air of external new income can't flow from clearance between them, the integral type synchronous heating to the air of external new income has been guaranteed, the heating route is optimized more, there is not difference in temperature and time difference, heat efficiency is higher, energy-saving effect is better.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
