The heat insulation sleeve 300 is sleeved outside the heat conduction ceramic part 200, on one hand, the heat insulation sleeve 300 can greatly reduce the direct transmission of the heat conduction ceramic part 200 to the shell of the electronic cigarette, the whole structure of the electronic cigarette is prevented from being too hot, on the other hand, the heat insulation sleeve 300 can also lock the heat dissipated out of the heat conduction ceramic part 200 in the heat insulation sleeve 300, and the heat dissipated out of the heat insulation sleeve 300 is intensively used for heating cigarettes and sucked fresh air. The metal heating element 100 includes a metal heating ring 110, a first conductor pin 120 and a second conductor pin 130, the first conductor pin 120 and the second conductor pin 130 are respectively electrically connected to the metal heating ring 110, and the first conductor pin 120 and the second conductor pin 130 are used as electrode portions of an electronic cigarette and are respectively connected to the positive electrode and the negative electrode of an external power supply to provide electric energy for the metal heating ring 110, so that the metal heating ring 110 is electrified to generate heat. The heat conductive ceramic member 200 includes a first heat conductor 210 and a second heat conductor 220, wherein the first heat conductor 210 is connected to the second heat conductor 220 to form an integrated heat conductive ceramic structure, so as to better cover the metal heating ring 110. The connection position of the first heat conductor 210 and the second heat conductor 220 is provided with an embedding cavity 230, and the metal heating ring 110 is accommodated in the embedding cavity 230, so that the metal heating ring 110 can be better coated, because the metal heating ring 110 has a certain thickness on the outer wall in the heat-conducting ceramic part 200, and the wear-resisting degree of the heat-conducting ceramic part 200 is also higher, compared with a layer of thin glass cement and other materials which are brushed and sintered, the heat-conducting ceramic part 200 can better protect the metal heating ring 110, and does not need to additionally brush sintered layers such as sintered glass cement, so that cigarettes do not need to be in contact with the metal heating ring 110, and the risk of introducing harmful substances such as heavy metals is avoided. An air inlet channel 240 is formed in the heat-conducting ceramic member 200, preferably, the air inlet channel 340 is disposed away from the metal heating ring 110, that is, the ceramic inner wall of the air inlet channel in the heat-conducting ceramic member 200 is shared with the outer wall of the metal heating ring, so that the metal heating ring 110 is completely isolated from the heat-conducting ceramic member 200, the air inlet channel 240 sequentially penetrates through the first heat conductor 210 and the second heat conductor 220, one end of the air inlet channel 240 is communicated with the outside air, and the other end of the air inlet channel 240 is directly communicated with the cigarette, so that when the heat-conducting ceramic member 200 is in a heat-conducting state, the outside fresh air flows along the air inlet channel 240, and thus when the outside fresh air flows through the air inlet channel 240, the fresh air is heated, and the outside fresh air must only enter through the air inlet channel 240, because the heat-conducting ceramic member 200 is tightly covered by the heat-insulating sleeve 300, the air that the external world newly entered can't flow out from both's clearance, has guaranteed the integral type synchronous heating to the air that newly enters of external world, and the heating route is more optimized, does not have the difference in temperature and time, and heat efficiency is higher, and energy-conserving effect is better. The thermal-insulated sleeve 300 cover is arranged in outside the heat conduction ceramic member 200, thermal-insulated sleeve 300 can greatly reduce on the one hand the heat direct transfer of heat conduction ceramic member 200 to the electron cigarette casing, avoids electron cigarette overall structure to cross to scald, and on the other hand, thermal-insulated sleeve 300 can also lock the heat of losing out of heat conduction ceramic member 200 in thermal-insulated sleeve 300 for the heat that thermal-insulated sleeve 300 loses out is used for heating cigarette and by inspiratory fresh air with concentrating. Specifically, the heat insulation sleeve 300 is a cylindrical structure, and the inner wall thereof is tightly attached to the heat conductive ceramic member 200, so that the structural stability is better, and the heat insulation and energy saving effects are also better. In order to make the order flow through the air inlet channel with erode cigarette newly-entered air can mix the smog that cigarette produced and enter into the cigarette holder of electron cigarette smoothly in the lump, generally need make cigarette with thermal-insulated sleeve has certain clearance, so, then means the diameter of heat conduction ceramic member will be greater than the diameter of cigarette, this is because the diameter of heat conduction ceramic member need with thermal-insulated sleeve's internal diameter is the same to make the structural stability that both combine higher, so, the outer fringe of heat conduction ceramic member then difficult better direct contact with cigarette production can cause the loss of partial heat energy, and can't be better carry out the abundant heating to cigarette, secondly, because cigarette with thermal-insulated sleeve has certain clearance, so when the electron cigarette is sucked, the electron cigarette can make cigarette more or less when rocking carry out the displacement in the thermal-insulated sleeve, the contact effect of the cigarette and the heat-conducting ceramic piece is influenced. In order to more effectively improve the heat energy utilization of the cigarette on the heat-conducting ceramic piece and reduce the displacement problem of the cigarette on the heat-insulating sleeve so as to improve the contact effect of the cigarette and the heat-conducting ceramic piece, in this embodiment, an embedding groove is disposed on an end of the first heat conductor away from the second heat conductor, and a diameter of the embedding groove is adapted to a diameter of a cigarette, so that, when the cigarette is inserted, the head of the cigarette is clamped in the embedding groove, firstly, the inner wall of the embedding groove can heat the cigarette more fully, contact surface area increase promptly, simultaneously, because the diameter in embedding groove is used for the diameter looks adaptation with cigarette, so the inner wall in embedding groove can carry out fixed action better to cigarette, can alleviate cigarette and be in thermal-insulated telescopic displacement problem improves cigarette with the contact effect of heat conduction ceramic member. Further, because the diameter of embedded groove is used for with the diameter looks adaptation of cigarette, so cigarette with space overflowed air between the embedded groove relatively can hinder comparatively, influence the smoothness nature that the user smoked, in this embodiment, spiral inlet channel has still been seted up to the inner wall of embedded groove, spiral inlet channel encircles the axial extension of first heat conductor, spiral inlet channel's one end extends to the bottom of embedded groove, spiral inlet channel's the other end extends to first heat conductor is kept away from on the terminal surface of the tip of second heat conductor, so, when the air of newly-income follow the inlet channel flows out the back, most newly-income air can be followed spiral inlet channel does the spiral rising flow, so, can enough ensure the smooth and easy degree when the air overflows to ensure the smoothness nature that the user smoked, and on the same reason, the spiral rising flow mode 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. Furthermore, the inner diameter of the heat insulation sleeve is gradually increased from one end close to the heat conduction ceramic piece to one end far away from the heat conduction ceramic piece, the inner diameter of the embedding groove is gradually increased from the bottom to the opening direction, and the inner diameter of the spiral air inlet channel is gradually decreased from the bottom of the embedding groove to the opening direction of the embedding groove, so that firstly, the cigarette can be clamped more from the bottom of the embedding groove and the bottom of the heat insulation sleeve due to the fact that the inner diameter of the heat insulation sleeve is gradually increased from one end close to the heat conduction ceramic piece to one end far away from the heat conduction ceramic piece and the inner diameter of the embedding groove is gradually increased from the bottom to the opening direction, and the contact area can be further improved, the heat contact effect is further improved, and meanwhile, the contact between the bottom of the cigarette and the inner wall of the embedding groove and the inner wall of the heat insulation sleeve is relatively compact, the air flow smoothness is reduced, and the inner diameter of the spiral air inlet channel is gradually reduced from the bottom of the embedding groove to the opening direction of the embedding groove, namely the inner diameter of the spiral air inlet channel is still relatively larger than the opening of the embedding groove at the bottom of the embedding groove, so that the problem is greatly relieved, and the air flow smoothness and the heating performance are both realized.
Compared with the prior art, the invention has at least the following advantages:
firstly, the electronic cigarette heating component has a double heating function, namely one heating mode is direct contact heating of the cigarette by a heater, 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 part 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 part is higher than the outer surface, so that the newly-entered air is divided into two strands and has temperature difference, the heat energy is not favorably and effectively utilized, and the energy-saving effect is poorer. The heat conduction ceramic member of present case is because endocyst metal heating ring, the whole heat conduction effect of heat conduction ceramic member is fairly even and stable, and the air that external new income can only circulate along the inlet channel, so, when external new income air current was through the inlet channel, can be heated, and external new income air also must only be got into by the inlet channel, this is because heat conduction ceramic member is by thermal-insulated sleeve cladding locking, the air that external new income can't flow from clearance between them, the integral type synchronous heating to external new income air has been guaranteed, heating path is optimized more, there is not difference in temperature and time difference, heat efficiency is higher, energy-conserving effect is better.
Secondly, the electron cigarette heating element of present case, when preparing, arrange the metal heating member in the mould earlier, then pour into first ceramic thick liquids and second ceramic thick liquids respectively at the both ends of mould, in order to form first heat-conducting body and the second heat-conducting body of cladding in the metal heating member jointly respectively, make first heat-conducting body and second heat-conducting body jointly with the metal heating member cladding, so, avoid the metal heating member directly to expose in the problem that the periphery leads to the wearing and tearing of metal heating member, produce the heat when the metal heating member circular telegram, and the heat can be conducted respectively to first heat-conducting body and second heat-conducting body surface.
Finally, because the heating element is integrally attached to the surface of the heat-conducting ceramic in a patch or circuit printing manner, when the metal heating element itself conducts electricity and generates heat, the heating path of the metal heating element is not reasonable enough, because the metal heating element has two heating regions and two heating time differences, for the two heating regions, because the thickness of the sintering layer is relatively thin, the temperature of the sintering layer right above the metal heating element is certainly much higher than that of the rest sintering layers, because the heat of the rest sintering layers still 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, the temperature is directly transferred by the metal heating element, but because the heat of the rest sintering layers still needs to be transferred through the heat-conducting ceramic, and the problem of time lag exists. Therefore, a problem of unreasonable heating paths may be caused. However, the first ceramic slurry and the second ceramic slurry in the mould are respectively injected into the two ends of the mould by the scheme, when glue is poured, the consistent injection quantity of the two ends of the mould can be ensured, the distance between the end surface of the first heat conductor and the metal heating ring of the metal heating element and the distance between the end surface of the second heat conductor and the metal heating ring of the metal heating element have smaller or even zero difference, and further the temperature on the surface of the electronic cigarette heating component is more uniform, the integral heating path is optimized, and the problem of poor heating effect of the electronic cigarette is solved.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
