Description

Technical Field

[0001] The present invention relates to the technical field of electronic cigarettes, and in particular to an atomizing core and an electronic cigarette using a planar porous ceramic as a heater. Background Art

[0002] At present, the development trend of the electronic cigarette industry is to rapidly evolve from the previous structure of oil storage cotton + oil guide cotton + heating wire to the structure of transparent oil tank + isolation / structural metal parts + oil guide cotton + heating wire. This is because the oil storage cotton will definitely have residual oil, which cannot be fully utilized, resulting in a certain degree of waste, while the transparent oil tank structure without oil storage cotton does not have such a problem; in addition, there is another trend in the electronic cigarette industry now, which is to develop in the direction of large puffs, long life, and refillable oil. The design life of electronic cigarette products has developed from the previous common 600 / 1000 puffs (one-time) to the current tens of thousands of puffs, and even the combination of the refillable oil function can achieve a larger number of puffs. In this context, the original design of heating wires combined with cotton cores made of iron-chromium-aluminum / nickel-chromium / stainless steel and other materials can no longer meet the design requirements.

[0003] For the common transparent oil tank large-mouth electronic cigarette products on the market, they contain more metal parts and small components, which brings certain pressure on cost and assembly.

[0004] At present, the common transparent oil tank large-mouth electronic cigarette products on the market still use traditional metal heating wires, which are made of iron-chromium-aluminum / nickel-chromium / stainless steel, etc. During long-term use, they are not in sufficient contact with the oil-conducting cotton, and under the influence of the chemical environment of the smoke oil and the high temperature of heating and atomization, there are serious problems such as carbon deposition, and even corrosion problems, as well as heavy metal pollution of chromium.

[0005] For this purpose, there is a planar porous ceramic heater in the prior art. The planar porous ceramic is used as the heater to avoid the problem of burning and producing odor when the heating layer is in direct contact with the atomized liquid, thereby ensuring the long-term stability of use, and also avoiding serious carbon deposition problems caused by the chemical environment of the smoke oil and the high temperature of heating and atomization.

[0006] However, the flat heater also has certain defects, that is, the e-liquid and smoke are easily mixed, resulting in a decrease in the smoking taste. Summary of the invention

[0007] In view of the deficiencies of the prior art, the present invention provides an atomizing core and an electronic cigarette using a planar porous ceramic as a heater, which solves the problem in the prior art that the tobacco oil and smoke of the planar heater are easily mixed, resulting in a deterioration in the smoking taste.

[0008] To achieve the above objectives, the present invention is implemented through the following technical solutions: an atomization core using a planar porous ceramic as a heater, comprising: a planar porous ceramic heater and a tank shell; wherein, one end of the tank shell has an opening, a central tube is provided in the tank shell, a packaging seat is provided between one end of the tank shell and the central tube, so that an oil storage cavity is formed in the tank shell; the other side of the packaging seat is pressed onto the edge of the planar porous ceramic heater, so that the hollow area of ​​the packaging seat guides the smoke generated by the planar porous ceramic heater into the central tube; an oil guiding component is provided between the side of the planar porous ceramic heater away from the central tube and the oil storage cavity, so that the smoke oil side and the smoke side of the planar porous ceramic heater are separated into two sides.

[0009] Furthermore, the planar porous ceramic as a heater includes a planar ceramic and a heating layer, the planar ceramic has a porous area and a non-porous area, the porous area is used to leave a channel for smoke, and the heating layer is buried in the non-porous area to make the planar porous ceramic heater generate heat; the planar ceramic includes at least two ceramic layers, and the heating layer is located between any two ceramic layers.

[0010] Furthermore, the size of the ceramic layer with the heating layer is larger than that of the ceramic layer without the heating layer, so that the outer edge of the ceramic layer with the heating layer protrudes from the ceramic layer without the heating layer, and the protruding part is the electrode area, on which a printed metal paste layer serving as an electrode is provided.

[0011] Furthermore, the oil-guiding component includes an atomization bin, which includes a bin body located on the side of the packaging seat away from the convex ring and an oil-guiding channel for guiding the tobacco oil in the oil storage cavity into the bin body; the planar porous ceramic heater is accommodated in the bin body; oil-guiding cotton is accommodated on the side of the bin body away from the central tube, so that the planar porous ceramic heater heats the tobacco oil on the oil-guiding cotton.

[0012] Furthermore, the oil guide channel is an arc-shaped oil guide cup or an oil guide pipe.

[0013] Furthermore, the packaging seat includes a seat body for packaging the storage shell and a lower extension portion arranged on the side of the seat body close to the planar porous ceramic heater, and the lower extension portion is pressed on the edge area of ​​the surface of the planar porous ceramic heater; a first sealing ring is provided between the seat body and the storage shell, a second sealing ring is provided between the seat body and the center tube, and a third sealing ring is provided between the lower extension portion and the planar porous ceramic heater; an oil outlet hole for accommodating an oil guide channel is provided on the seat body.

[0014] Furthermore, the chamber shell is provided with an extension portion toward the planar porous ceramic heater; and further comprises a press-fitting component, wherein the press-fitting component comprises a pressing cylinder nested in the extension portion and a support beam located in the pressing cylinder for pressing the atomization chamber.

[0015] Furthermore, it also includes a PCB board, which is located on a side of the support beam away from the atomization chamber; an electrode is provided on the PCB board in an area opposite to the printed metal paste layer serving as an electrode, a conductor is welded on the electrode, the conductor extends to the printed metal paste layer serving as an electrode, and an elastic electrode capable of contacting the printed metal paste layer serving as an electrode is fixed on the conductor.

[0016] Furthermore, it also includes an assembly seat, which is nested in the pressing cylinder, and the PCB board is assembled in the assembly seat.

[0017] On the other hand, an embodiment of the present invention further provides an electronic cigarette, characterized in that it includes the above-mentioned atomization core using the planar porous ceramic as a heater; it also includes a shell, and the atomization core is assembled in the shell; a battery core is provided at one end of the shell away from the atomization core, and an electrode electrically connected to the battery core is provided on the PCB board.

[0018] The present invention has the following beneficial effects:

[0019] (1) The atomizer core and electronic cigarette using a planar porous ceramic as a heater can separate the smoke and the smoke oil on the upper and lower sides of the planar porous ceramic heater, that is, the smoke and the smoke oil have their own flow channels, thereby preventing the smoke and the smoke oil from coexisting in the same space, ensuring that the discharge of the smoke is not blocked by the smoke oil, and also preventing the smoke from containing the smoke oil that has not been atomized, thereby improving the smoking taste.

[0020] (2) The atomizing core and electronic cigarette using planar porous ceramic as the heater can further increase the amount of smoke by passing through the hole area through the planar porous ceramic, thereby avoiding the problem of poor uniformity of smoke oil atomization dispersion, thereby improving the taste of the electronic cigarette. At the same time, because the heating layer is buried in the non-hole area, the heating layer is protected by the planar ceramic and will not contact the atomizing liquid, thus avoiding exposure of the heating layer, thereby avoiding the burning smell caused by direct contact between the heating layer and the atomizing liquid, ensuring the long-term stability of use, and avoiding serious carbon deposition problems under the chemical environment of the smoke oil and the high temperature of the heating atomization, avoiding corrosion problems, and avoiding heavy metal pollution of chromium. Therefore, the mesh ceramic heating wire further improves the taste of the electronic cigarette.

[0021] (3) The atomizer core and electronic cigarette using a planar porous ceramic as a heater are provided with oil-conducting cotton. The oil-conducting cotton can have a good oil-conducting rate to ensure high-quality atomization and flavor restoration. The oil-conducting cotton is located below the planar porous ceramic heater and can maintain the stability of the amount of oil in the chamber to ensure that the oil does not cross the upper surface of the planar porous ceramic heater, thereby further ensuring that the smoke generated after heating is separated from the unatomized oil to avoid mixing the two, thereby further improving the smoking taste.

[0022] (4) The atomizer core and the electronic cigarette using the planar porous ceramic as the heater have all parts tightly packaged and will not leak oil.

[0023] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0045] According to the following Figure 1 - Fig.18An atomizing core and an electronic cigarette using a planar porous ceramic as a heater are described in an embodiment of the present invention.

[0046] In a first aspect, an embodiment of the present invention provides an atomization core using a planar porous ceramic as a heater.

[0047] It includes a planar porous ceramic heater 200 and an oil tank 300 .

[0048] Among them, the oil tank 300 includes an opening at one end of the tank shell 310, and a central tube 320 is provided in the tank shell 310. The central tube 320 serves as a passage for the atomized smoke. A packaging seat 700 is provided between one end of the tank shell 310 and the central tube 320, so that an oil storage cavity is formed in the tank shell 310; the other side of the packaging seat 700 is pressed onto the edge of the planar porous ceramic heater 200, so that the hollow area of ​​the packaging seat 700 guides the smoke generated by the planar porous ceramic heater 200 into the central tube 320, and an oil guide component is provided between the side of the planar porous ceramic heater 200 away from the central tube 320 and the oil storage cavity, and the oil guide component can guide the smoke oil in the oil storage cavity to Figure 1 The bottom of the planar porous ceramic heater 200 is shown from the perspective.

[0049] Reference Figure 1 - Figure 5 It can be better understood that when the planar porous ceramic heater 200 is heated, the tobacco oil below it can be heated to form smoke, and the smoke can flow upward and pass through the hollow area of ​​the packaging seat 700 into the central tube 320, that is, the smoke and tobacco oil are separated on the upper and lower sides of the planar porous ceramic heater 200, avoiding the coexistence of smoke and tobacco oil in the same space, ensuring that the discharge of smoke is not blocked by tobacco oil.

[0050] Therefore, the atomization core using a planar porous ceramic as a heater provided in an embodiment of the present invention can separate the smoke and the smoke oil on the upper and lower sides of the planar porous ceramic heater 200, that is, the smoke and the smoke oil have their own flow channels, thereby avoiding the smoke and the smoke oil from coexisting in the same space, ensuring that the discharge of the smoke is not blocked by the smoke oil, and also avoiding the situation where the smoke contains smoke oil that has not been atomized, thereby improving the smoking taste.

[0051] Preferably, the material of the storage shell 310 is polyethylene or glass.

[0052] Among them, the planar porous ceramic heater 200 includes a planar ceramic and a heating layer. The planar ceramic has a hole area 230 and a non-hole area. The hole area 230 is used to leave a channel for smoke. The heating layer is buried in the non-hole area to make the planar porous ceramic heater generate heat. The planar ceramic here includes at least two ceramic layers, and the heating layer is located between any two ceramic layers.

[0053] In addition, the hole area 230 is obtained by mechanically punching holes on the flat ceramic, and the non-punched positions form non-hole areas.

[0054] It is worth noting that the hole area 230 is used to leave a channel for the smoke. After the smoke oil is heated to form smoke, the smoke can further increase the amount of smoke through the hole area 230, thereby avoiding the problem of poor uniformity of smoke oil atomization dispersion, and thus improving the taste of the electronic cigarette. At the same time, because the heating layer is buried in the non-hole area, the heating layer is protected by the flat ceramic and will not contact the atomized liquid, avoiding exposure of the heating layer, thereby avoiding the burning smell caused by direct contact between the heating layer and the atomized liquid, ensuring the long-term stability of use, and avoiding serious carbon deposition problems under the chemical environment of the smoke oil and the high temperature of heating atomization, avoiding corrosion problems, and avoiding heavy metal pollution of chromium. Therefore, the mesh ceramic heating wire further improves the taste of the electronic cigarette.

[0055] In addition, ceramics, as an inert material, are resistant to high temperatures and do not react with various acids, alkalis, and e-liquids. They have good stability and can solve the reliability problem of heating wires in electronic cigarettes over an ultra-long life cycle.

[0056] Optionally, the material of the porous ceramic is Al2O3, ZrO2, ZTA, AlN, SiC, Si3N4 or a composite ceramic material.

[0057] Preferably, the thickness of the single ceramic layer is 0.1 mm-2 mm.

[0058] Furthermore, the size of the ceramic layer with the heating layer is larger than that of the ceramic layer without the heating layer, so that the outer edge of the ceramic layer with the heating layer protrudes from the ceramic layer without the heating layer, and the protruding part is the electrode area 211, and a printed metal paste layer 250 serving as an electrode is provided on the electrode area 211.

[0059] Therefore, the atomizer core using the planar porous ceramic as the heater provided in the embodiment of the present invention can conveniently energize the heating layer through the printed metal paste layer 250 serving as the electrode on the electrode area 211 .

[0060] For example, Figure 6 - Figure 8 As shown, two layers of planar ceramics are provided, including a porous ceramic layer 1 210 located on the upper layer and a porous ceramic layer 2 220 located on the lower layer, and the heating layer is located between the porous ceramic layer 1 210 and the porous ceramic layer 220, the diameter of the porous ceramic layer 1 210 is larger than the diameter of the porous ceramic layer 220, and the outer edge of the lower surface of the porous ceramic layer 1 210 is provided as an electrode area 211, and two groups of printed metal paste layers 250 serving as electrodes are provided on the electrode area 211 to form the positive and negative electrodes of the heating layer.

[0061] Preferably, the heating layer is a printed metal paste layer 240, preferably a heating layer with uniform line thickness and thickness; thereby, the atomization effect of the atomizer core can be improved. In addition, the metal paste layer 240 can be in different forms or patterns according to the design requirements for heating rate, uniformity, power distribution, etc. (refer to Figure 7 and Figure 8 There are two different patterns).

[0062] Optionally, the metal slurry layer 240 can be a screen-printed heating graphic layer, and the slurry can be sufficient and environmentally friendly and controllable, the printing process is simple, and the preparation cost is low.

[0063] Furthermore, the thickness of the metal paste layer 240 is between 10-50 um, and the maximum does not exceed 100 um; the printing width of the metal paste layer 240 is generally 100-500 um or wider, and the narrowest is 100 um.

[0064] In addition, when multiple ceramic layers are provided, there may be multiple metal slurry layers 240, and the multiple metal slurry layers 240 are correspondingly printed on the porous ceramic layer. This helps to improve the atomization efficiency and reduce the problem of poor taste in the initial stage of smoking the electronic cigarette. As a result, the taste of the electronic cigarette can be further improved.

[0065] It is particularly important that two or more layers of porous ceramics are first pressed together and then co-fired at high temperature during production.

[0066] Combination Figure 2 , Figure 5 , Fig. 9 and Fig.10 As shown, the oil guide component mentioned above includes an atomization bin 900, and the atomization bin 900 includes a bin body 920, which is located on the side of the packaging seat 700 away from the convex ring 330, and the planar porous ceramic heater 200 is accommodated in the bin body 920, and oil guide cotton 940 is accommodated below the planar porous ceramic heater 200, and an oil guide channel for guiding oil is configured between the bin body 920 and the oil storage cavity (the oil guide channel needs to pass through the packaging seat 700), so that the smoke oil in the oil storage cavity can enter the oil guide cotton 940 in the bin body 920.

[0067] The oil-conducting cotton 940 can store the tobacco oil introduced into the tank body 920 by the oil-conducting channel, and can maintain the stability of the tobacco oil amount in the tank body 920, ensuring that the tobacco oil does not cross the upper surface of the planar porous ceramic heater 200, thereby further ensuring that the smoke generated after heating is separated from the unatomized tobacco oil, avoiding the mixing of the two, and further improving the smoking taste.

[0068] Among them, the above Fig.10 include Fig.10 (a) and Fig.10 (b) Fig.10(a) is a schematic diagram showing the oil-conducting cotton 940 retained after the atomization chamber 900 is cut open. Fig.10 (b) Fig.10 a is a schematic diagram of the unassembled oil-conducting cotton 940.

[0069] Therefore, the planar porous ceramic heater 200 can heat the oil on the oil-conducting cotton 940. The heated smoke can directly flow upward through the hole area 230 and enter the central tube 320 through the hollow area of ​​the packaging seat 700 for inhalation. During the whole process, the oil and smoke do not contact each other, avoiding a hard smoking taste.

[0070] Preferably, an oil inlet 921 is provided on the storage body 920 at a position opposite to the oil guide channel.

[0071] Preferably, the tank body 920 and the oil guide channel are integrally formed and are both injection molded parts.

[0072] In addition, the lower end of the warehouse body 920 should be sealed, that is, the lower end thereof has a bottom plate 930, and an air hole 931 is provided in the area on the bottom plate 930 opposite to the warehouse body 920 for external gas to enter the warehouse body 920 for suction.

[0073] Preferably, the oil guide channel can be Fig. 9 and Fig.10 The arc-shaped oil guide cup 910 is an arc-shaped cup-shaped structure having an interlayer, in which the smoke oil can flow, and the smoke oil in the oil storage cavity can enter the storage body 920 through the interlayer.

[0074] in, Fig.11 (a) is an overall view of the package seat 700, Fig.11 (b) is a cross-sectional view of the package seat 700.

[0075] On the other hand, the oil guide channel may also be an oil guide pipe (not shown in the figure).

[0076] Combination Figure 2 , Figure 3 , Figure 5 and Fig.11 As shown, the packaging seat 700 includes a seat body 710 for packaging the housing shell 310 and a lower extension portion 712 arranged on the side of the seat body 710 close to the planar porous ceramic heater 200. The lower extension portion 712 is used to be pressed on the edge area of ​​the surface of the planar porous ceramic heater 200, thereby preventing the smoke generated by the planar porous ceramic heater 200 from escaping outward and ensuring that the smoke can only flow along the hollow area of ​​the packaging seat 700 to the center tube 320.

[0077] Preferably, a first sealing ring 720 is provided between the seat body 710 and the housing 310 , and a second sealing ring 730 is provided between the seat body 710 and the central tube 320 , thereby preventing the oil in the oil storage chamber from leaking from the seat body 710 .

[0078] In addition, a third sealing ring 740 is provided between the lower extension 712 and the planar porous ceramic heater 200, which can improve the sealing performance between the planar porous ceramic heater 200 and the packaging seat 700 and further prevent smoke from escaping outward.

[0079] It is worth noting that an oil outlet hole 711 for accommodating the oil guide channel is provided on the seat body 710, and the upper end of the oil guide channel is inserted into the oil outlet hole 711. Preferably, a sealing gasket is also provided on the inner wall of the oil outlet hole 711 to further prevent the leakage of smoke oil.

[0080] like Figure 1 and Figure 3 As shown, in order to facilitate locking the atomization bin 900, the bin shell 310 here is provided with an extension portion 340 toward the direction of the planar porous ceramic heater 200, and the pressing part 800 is nested in the extension portion 340, which includes a pressing cylinder 810 and a support beam 820 located in the pressing cylinder 810 for pressing the atomization bin 900; in the present embodiment, the upper end of the pressing cylinder 810 is pressed against the packaging seat 700 to lock the position of the packaging seat 700, and the support beam 820 is pressed against the bottom plate 930, thereby locking the position of the atomization bin 900.

[0081] On the other hand, the pressing cylinder 810 can also be assembled in the extension portion 340 by means of threaded connection.

[0082] Therefore, the planar porous ceramic provided in the embodiment of the present invention as the atomization core of the heater can more conveniently fix the packaging seat 700 and the atomization chamber 900.

[0083] Combination Figure 2 - Figure 5 As shown, in order to achieve electrical connection of the printed metal paste layer 250 serving as an electrode, a PCB board 600 is also provided.

A conductor 670 is welded on the electrode 660, and the conductor 670 extends to the printed metal paste layer 250 serving as an electrode. An elastic electrode 630 capable of contacting the printed metal paste layer 250 serving as an electrode is fixed on the conductor 670, so that the printed metal paste layer 250 serving as an electrode can be electrically connected to the electrode 660 through the elastic electrode 630 and the conductor 670.

[0084] Optionally, the conductor 670 is a metal column or a wire.

[0085] Optionally, the elastic electrode 630 is a V-shaped structure, a U-shaped structure or a C-shaped structure.

[0086] Preferably, Fig.12 and Fig.13 As shown, an insulating sleeve 640 is sleeved on the outside of the conductor 670, and a fixing seat 650 is provided at the lower end of the insulating sleeve 640, and the fixing seat 650 is locked on the PCB board 600 by welding or bolt connection.

[0087] In addition, it is worth mentioning that a second avoidance hole 821 for the conductor 670 to pass through is provided on the support beam 820 , and a first avoidance hole 932 for the conductor 670 to pass through is opened on the bottom plate 930 .

[0088] Furthermore, the microphone 620 and the controller are assembled on the PCB 600. The microphone 620 is preferably assembled on the lower surface of the PCB 600 ( Fig.12 The middle microphone 620 is assembled on the upper surface of the PCB board 600). When the user inhales, the airflow reaches the position of the microphone 620, which detects the change of the air pressure. The controller can control the battery core 400 to supply power, that is, the surface porous ceramic heater 200 starts to heat up.
