Specific embodiments

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0029] Next, according to Figure 1 - Figure 6 Describe the planar porous ceramic heater, atomization core and electronic cigarette of the present utility model.

[0030] In combination with Figure 1 - Figure 3 As shown, the present utility model discloses a planar porous ceramic heater 6, including a planar ceramic and a heating layer. The planar ceramic has a pore area 601 and a non-pore area 602. The pore area 601 is used to leave a channel for the smoke, and the heating layer is buried on the non-pore area 602. Thus, when the heating layer is powered on and heated, it can conduct heat to the entire planar porous ceramic heater 6, so that the planar porous ceramic heater 6 heats and atomizes the atomization liquid.

[0031] In addition, the pore area 601 is obtained by mechanically punching holes on the planar ceramic. The punching positions form the pore area 601, and the non-punched positions form the non-pore area 602.

[0032] Secondly, when the heating layer is arranged on the non-pore area 602, a heating layer with uniform line thickness and thickness is preferably used. Thereby, the atomization effect of the atomization core is improved.

[0033] Furthermore, the above-mentioned hole region 601 is used to leave a passage for the smoke, further increasing the amount of smoke, thereby avoiding the problem of poor uniformity of e-liquid atomization and dispersion, and thus improving the taste of the electronic cigarette. At the same time, since the heating layer is buried in the non-hole region 602, the heating layer is protected by the planar ceramic and does not come into contact with the atomization liquid, avoiding the exposure of the heating layer. Therefore, it can avoid the problem of direct contact combustion between the heating layer and the atomization liquid, ensuring the long-term stability of use. It also avoids problems such as severe carbon deposition under the promotion of the e-liquid chemical environment and the high temperature of heating and atomization, avoids the problem of corrosion, and also avoids the problem of heavy metal pollution of chromium. Therefore, the mesh ceramic heating wire further improves the taste of the electronic cigarette.

[0034] In addition, as an inert material, ceramics are high-temperature resistant and do not react with various acids, alkalis, and e-liquids, etc., and have good stability, which can solve the reliability problem of the heating wire in the electronic cigarette during the ultra-long life cycle.

[0035] Preferably, the material of the porous ceramic is Al2O3, ZrO2, ZTA, AlN, SiC, Si3N4 or composite ceramic material.

[0036] Furthermore, the above-mentioned planar ceramic includes multiple ceramic layers, the heating layer is located between any two ceramic layers, and any two ceramic layers are sintered and fixed. For example Figure 1 - Figure 3 As shown, a double-layer planar porous ceramic heater is provided, namely porous ceramic layer one 61 and porous ceramic layer two 62. The heating layer is located between porous ceramic layer one 61 and porous ceramic layer two 62, so that the heating layer can be covered by porous ceramic layer one 61 and porous ceramic layer two 62. Then the heating layer is protected. Also, due to the stable thermal conductivity of the ceramic, uniform heating of the entire planar porous ceramic heater 6 is achieved.

[0037] Preferably, the thickness of a single ceramic layer is 0.1 mm - 2 mm

[0038] Preferably, the heating layer is a printed metal paste layer 64 printed on one of the ceramic layers. The printed metal paste layer 64 is provided on one side of a ceramic layer close to another adjacent ceramic layer. For example, in the state of the above double-layer porous ceramic heater, it is printed on porous ceramic layer one 61, and an electrode region is also provided on porous ceramic layer one 61, and a printed metal paste layer 65 serving as an electrode is also provided on the electrode region, so that the printed metal paste layer 64 can be powered on.

[0039] Preferably, the printed metal paste layer 64 can be of different forms or patterns according to the design requirements for heating rate, uniformity, power distribution, etc.

[0040] Optionally, the printed metal paste layer 64 can use screen printing to form a heating pattern layer. The selected paste is sufficient, environmentally friendly, and controllable. The printing process is simple and the preparation cost is low.

[0041] Furthermore, the thickness of the printed metal paste layer 64 is between 10 - 50 um, and the maximum does not exceed 100 um; the printing width of the printed metal paste layer 64 is generally 100 - 500 um or wider, and the narrowest is 100 um.

[0042] In addition, when multiple ceramic layers are provided, there can be multiple printed metal paste layers 64, and the multiple printed metal paste layers 64 are correspondingly printed on the porous ceramic layer. This helps to improve the atomization efficiency and reduce the problem of poor taste at the initial stage of vaping an e - cigarette. Thus, the taste of this e - cigarette can be further improved.

[0043] Secondly, when producing two or more layers of porous ceramics, they are first pressed together and then obtained through high - temperature co - firing.

[0044] Moreover, an electrode area is also provided on the ceramic layer with the printed metal paste layer 64, and a printed metal paste layer 65 serving as an electrode is provided on the electrode area. For example, when the printed metal paste layer 64 is printed on the porous ceramic layer 61, the printed metal paste layer 65 serving as an electrode is also printed on the porous ceramic layer 61, so that the printed metal paste layer 65 serving as an electrode and the printed metal paste layer 64 are on the same layer of porous ceramic.

[0045] In the above solution, a window 63 needs to be provided in the area of the outermost ceramic layer opposite to the electrode area to form a space for the electrical connection of the printed metal paste layer 65 serving as an electrode. For example Figure 3 in, the porous ceramic layer 62 serves as the outermost porous ceramic layer, and a window 63 is provided at a position opposite to the electrode area thereon, so that the window 63 can expose the printed metal paste layer 65 serving as an electrode, facilitating the connection of the printed metal paste layer 65 serving as an electrode to electricity. Therefore, the e - cigarette provided by the embodiment of the present utility model using a planar porous structure can facilitate the power supply to the printed metal paste layer 64. The outermost porous ceramic layer has a window 63 provided in the corresponding area of the electrode area, and the window 63 is used to expose the printed metal paste layer 65 serving as an electrode.

[0046] Combined Figure 4 and Figure 5As shown in the figure, on the other hand, an embodiment of the present utility model further provides an atomization core, which includes the above-mentioned planar porous ceramic heater 6, and further includes an assembly seat 3 for assembling the planar porous ceramic heater 6. A convex frame 31 with a frame opening is provided on one surface of the assembly seat 3. The planar porous ceramic heater 6 is located within the convex frame 31. A liquid guide cotton 4 is assembled on one side of the convex frame 31 close to the frame opening, so that the liquid guide cotton 4 can introduce the atomization liquid into the planar porous ceramic heater 6, and thus the planar porous ceramic heater 6 can heat and atomize the atomization liquid.

[0047] Preferably, the assembly seat 3 is injection molded.

[0048] One side of the above-mentioned planar porous ceramic heater 6 away from the liquid guide cotton 4 is defined as the atomization surface. For example Figure 4 in the lower surface of the porous ceramic layer two 62 is used as the atomization surface. A smoke tube 17 is provided at a position of the convex frame 31 close to the atomization surface. The smoke tube 17 is used to convey the atomized smoke, so that the passage of the smoke and the atomization liquid on the liquid guide cotton 4 are isolated, that is, the atomization liquid and the smoke do not contact each other. Thus, it is possible to avoid the atomization liquid in the sucked smoke, and improve the sucking purity.

[0049] Since one side of the planar porous ceramic heater 6 away from the liquid guide cotton 4 is defined as the atomization surface, a heightening block 36 is provided on one side of the convex frame 31 close to the assembly seat 3 to raise the planar porous ceramic heater 6, so as to reserve a gap between the atomization surface and the bottom surface of the convex frame 31. This gap allows the atomized smoke to enter the smoke tube 17 and be discharged from the smoke tube 17. Thus, the storage capacity of the atomized smoke can be increased and the suction resistance can be reduced.

[0050] Such as Figure 5 and Figure 6 shown, in order to prevent the oil liquid absorbed by the liquid guide cotton 4 from being conducted to the printed metal paste layer 65 serving as an electrode, an opening 34 for the electrode area to extend out of the convex frame 31 is provided on one side of the convex frame 31 close to the printed metal paste layer 65 serving as an electrode. Thus, the electrode area of the planar porous ceramic heater 6 can extend out of the convex frame 31 through the opening 34, and then the oil liquid absorbed by the defined liquid guide cotton 4 cannot be conducted to the printed metal paste layer 65 serving as an electrode, avoiding the situation of generating a burnt smell when the oil liquid contacts the printed metal paste layer 65 serving as an electrode.

[0051] Preferably, sealing rings one 35 for sealing are provided on four side surfaces of the opening 34, so that the atomization liquid on the planar porous ceramic heater 6 and the liquid guide cotton 4 does not leak out from the position of the opening 34.

[0052] In addition, when assembling the planar porous ceramic heater 6, the electrode area should face the side close to the assembly seat 3, that is, in Figure 4 and Figure 5Among them, the electrode area should face downward, and a PCB board 7 should be fitted on one side of the assembly base 3 away from the convex frame 31. Two pole columns 8 serving as positive and negative electrodes should be installed at positions on the PCB board 7 opposite to the electrode area. Through holes 33 should be opened at positions on the assembly base 3 opposite to the pole columns 8. The pole columns 8 can pass through the through holes 33 and contact the printed metal paste layer 65 serving as an electrode, so as to energize the printed metal paste layer 65 serving as an electrode. Therefore, in this embodiment, it is convenient to energize the printed metal paste layer 65 serving as an electrode and the PCB board 7.

[0053] Preferably, an elastic conductor, such as a V-shaped conductive contact in the prior art, is assembled at the upper end of the pole column 8.

[0054] Such as Figure 6 , thirdly, the present utility model also provides an electronic cigarette, which includes the above-mentioned atomization core, and also includes an outer shell 11. A smoke channel 12 is arranged in the middle of the outer shell 11, and a packaging base 14 is embedded at one end of the outer shell 11. An oil storage chamber is formed among the outer shell 11, the smoke channel 12 and the packaging base 14. The oil storage chamber is used to store atomization liquid, and the above-mentioned atomization core is located in the packaging base 14, and the frame opening should be close to the oil storage chamber to facilitate the atomization liquid in the oil storage chamber to enter the liquid guide cotton 4.

[0055] A mist outlet 16 is arranged in the middle of the packaging base 14. One end of the mist outlet 16 is embedded in the smoke channel 12. A smoke tube 17 is communicated with the mist outlet 16. Then, the smoke in the smoke tube 17 can reach the smoke channel 12 through the mist outlet 16 and reach the position of the mouthpiece 13 for the user to suck.

[0056] Moreover, an oil inlet hole 15 is also arranged on the side part of the packaging base 14, so as to introduce the atomization liquid in the oil storage chamber into the liquid guide cotton 4.

[0057] Preferably, a second sealing ring 10 is defined between the outer side wall of the packaging base 14 and the inner wall of the outer shell 11. The second sealing ring 10 here can prevent the atomization liquid in the oil storage chamber from leaking from the periphery of the packaging base 14.

[0058] In addition, it is best to fit the end face of the frame opening of the convex frame 31 to the surface of the packaging base 14, and a suitable third sealing ring 37 is arranged on the end face of the frame opening to prevent the atomization liquid in the convex frame 31 from leaking from the frame opening position.

[0059] Furthermore, an outer shell 2 is embedded at one end of the outer shell 11 close to the packaging base 14. A battery cell 5 is arranged in the outer shell 2, and the battery cell 5 is electrically connected to the PCB board 7.

[0060] In addition, air holes are formed in both the PCB board 7 and the outer shell 2, so that when the user sucks, the outside air can enter the smoke passage 12 through the air holes to mix with the smoke. A microphone and a controller are also assembled on the PCB board 7. The microphone serves as a detection sensor for whether there is air flow. When air flow is detected, the controller controls the circuit for the power supply of the heating layer by the battery cell 5 to conduct.

[0061] It should be noted that in this text, terms such as "including", "comprising" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or further includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including one..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.

[0062] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
