DETAILED DESCRIPTION
[0024] The specific implementation modes of the present utility model are introduced with reference to the accompanying drawings.
[0025] refer to Figure 1 The figure is a schematic diagram of the three-dimensional structure of the double-fired ceramic heating core. The upper part of the double-fired ceramic heating core is the heating part, which is in the shape of a rectangular parallelepiped. An oil inlet hole 4 is arranged on each of the outer walls on both sides in the width direction. The lower part of the double-fired ceramic heating core is two conductive pins 13, and the two pins 13 are used to supply power to the double heating wire 7 inside the double-fired ceramic heating core.
[0026] refer to Figures 1 to 6 A double-fired ceramic heating core comprises an atomizing core tube 1, an oil absorbing layer 2 and a double-fired ceramic heating element 3 which are sequentially sleeved from outside to inside, the atomizing core tube 1 is provided with an oil inlet hole 4 leading to an oil cup, a part of the oil absorbing layer 2 is exposed at the oil inlet hole 4, the oil absorbing layer 2 is wrapped around the outer side of the double-fired ceramic heating element 3, the double-fired ceramic heating element 3 comprises a ceramic layer 5 and a double heating wire 7 sintered and fixed in the ceramic layer 5, the ceramic layer 5 penetrates an inner hole 6 connected to an airway, the double heating wire 7 comprises a first heating wire 8, a second heating wire 9 and a conductive member 10, the first heating wire 8 and the second heating wire 9 are connected in parallel through two conductive members 10, and are relatively arranged on the two inner side walls of the inner hole 6, the smoke oil in the oil cup penetrates from the oil inlet hole 4 to the oil absorbing layer 2, the smoke oil in the oil absorbing layer 2 infiltrates the ceramic layer 5, and is heated by the first heating wire 8 and the second heating wire 9 to be atomized into smoke that diffuses into the inner hole 6 and the airway.
[0027] The double-fired ceramic heating core of the present embodiment is provided with double heating wires 7 on the two inner side walls of the inner hole 6 of the ceramic layer 5. The inner hole 6 of the ceramic layer 5 serves as an atomization chamber communicated with the airway. The ceramic layer 5 is quickly heated at the same time by the first heating wire 8 and the second heating wire 9 connected in parallel. The heating area is large, and the smoke oil in the atomization oil absorption layer 2 and the ceramic layer 5 can be quickly heated to generate a large amount of smoke at the inner hole 6, which is blown to the mouthpiece through the airway for the user to inhale, and the smoke explosion force is relatively high.
[0028] In order to improve the quality of the double heating wire 7, in this embodiment, reference Figure 3 The double heating wire 7 is formed by integral stamping and bending.
[0029] It is understandable that with such a setting, the integrated stamping and bending forming can reduce the welding process and the number of parts, so that the double heating wire 7 has no welding points, the amount of heat deformation at each location of the double heating wire 7 is the same, and desoldering will not occur, thereby ensuring the service life of the double heating wire 7.
[0030] In order to better atomize the e-liquid, in this embodiment, reference Figure 5 The first heating wire 8 and the second heating wire 9 are both provided with inner side walls exposed from the inner hole 6 , and the first heating wire 8 and the second heating wire 9 are both provided with honeycomb-shaped heating grids 11 .
[0031] It can be understood that, with such a configuration, the ceramic layer 5 is a sintered porous ceramic layer 5, and the smoke oil in the ceramic layer 5 needs to diffuse into the inner hole 6 through the micropores of the ceramic layer 5 after being atomized. The first heating wire 8 and the second heating wire 9 pass through the heating grid 11 to avoid blocking the smoke from diffusing out of the ceramic layer 5. At the same time, the heating grid 11 is used to expand the heating area of the first heating wire 8 and the second heating wire 9 to increase the atomization rate.
[0032] In order to ensure that the heating grid 11 can be stably attached to the inner wall of the inner hole 6, in this embodiment, Figure 6 The edge of the heating grid 11 is bent to form a connecting block 12 buried in the ceramic layer 5.
[0033] It can be understood that, with such a configuration, the connecting blocks 12 on the upper and lower sides are vertically buried in the ceramic layer 5. During the sintering process, the connecting blocks 12 are completely fixed in the ceramic layer 5, so that the heating grid 11 is stably fixed on the inner wall of the inner hole 6 and will not fall off by itself, thereby ensuring the service life of the first heating wire 8 and the second heating wire 9.
[0034] In order to ensure that the dual heating wire 7 is stably fixed on the ceramic layer 5, in this embodiment, reference Figure 2 A portion of the conductive member 10 is buried in the ceramic layer 5 , and another portion is exposed from the inner hole 6 of the ceramic layer 5 .
[0035] It can be understood that, with such an arrangement, the combined length of the first heating wire 8 and the two conductive parts 10 on both sides is greater than the length of the inner hole 6, the first heating wire 8 is exposed on the inner wall of the inner hole 6, half of the conductive part 10 is exposed in the inner hole 6, and the other half is buried in the ceramic layer 5, and through sintering, the conductive part 10 can be fixed in the ceramic layer 5, and the second heating wire 9 is the same, so that the double heating wire 7 is stably fixed on the ceramic layer 5.
[0036] In order to realize the parallel connection of the first heating wire 8 and the second heating wire 9, in this embodiment, Figure 2 and Figure 3 The conductive member 10 is a U-shaped conductive member 10 , and the conductive member 10 is connected with a conductive pin 13 , and the pin 13 is located at the air inlet side of the inner hole 6 of the ceramic layer 5 .
[0037] It can be understood that, with such a configuration, the inner hole 6 has a rectangular cross-section, the inner side walls of the two inner holes 6 for installing the first heating wire 8 and the second heating wire 9 are both flat, and the first heating wire 8 and the second heating wire 9 can be stably connected in parallel through the two U-shaped conductive parts 10. Each of the two U-shaped conductive parts 10 is provided with a pin 13, and the first heating wire 8 and the second heating wire 9 are energized at the same time through the two pins 13 connected to the power supply.
[0038] In order to facilitate the processing of the conductive member 10, in this embodiment, Figure 3 The conductive member 10 includes a first conductive sheet 14, a second conductive sheet 15 and a third conductive sheet 16. The second conductive sheet 15 is vertically arranged between the first conductive sheet 14 and the third conductive sheet 16. The first heating wire 8 is arranged between the two first conductive sheets 14 of the two conductive members 10. The second heating wire 9 is arranged between the two third conductive sheets 16 of the two conductive members 10. The first heating wire 8 and the two first conductive sheets 14 are arranged along a first plane. The second heating wire 9 and the two third conductive sheets 16 are arranged along a second plane. The first plane and the second plane are parallel to each other.
[0039] It should be further explained that the material of the dual heating wire 7 is nickel-chromium alloy, a heating grid 11 and a conductive member 10 are formed on a nickel-chromium alloy plate by stamping, and then the conductive member 10 is bent twice to form the parallel dual heating wires 7.
[0040] It can be understood that, with such an arrangement, the two conductive members 10 are bent twice at the same time to form the first conductive sheet 14, the second conductive sheet 15 and the third conductive sheet 16 respectively, so that the first heating wire 8 and the second heating wire 9 form two mutually parallel first planes and the second planes with their respective conductive sheets, which facilitates processing while also improving the processing quality of the dual heating wire 7, thereby improving the atomization quality.
[0041] In order to improve the atomization effect, in this embodiment, reference Figure 3The widths of the first heating wire 8 and the second heating wire 9 are both smaller than the length of the first conductive sheet 14 of the conductive member 10 .
[0042] It can be understood that, with such an arrangement, the first heating wire 8 and the second heating wire 9 need to be arranged in the center of the inner wall of the inner hole 6, so that the heated height of the first heating wire 8 and the second heating wire 9 is the same as the height of the oil inlet hole 4, and the first heating wire 8 and the second heating wire 9 can quickly heat the area where the smoke oil is most enriched, thereby improving the atomization effect. The third conductive sheet 16 of the conductive element 10 needs to be on the lower side of the inner hole 6, which makes the width of the first heating wire 8 and the second heating wire 9 smaller than the length of the first conductive sheet 14.
[0043] In order to reduce the amount of air entering the inner hole 6, in this embodiment, reference Figure 2 The second conductive sheet 15 is horizontally placed on the air inlet side of the inner hole 6 of the ceramic layer 5 , and the pin 13 is vertically arranged at the geometric center of the second conductive sheet 15 .
[0044] It is understandable that, by placing the pin 13 horizontally in this way, the aperture of the air inlet side of the inner hole 6 can be reduced, and the air intake of the inner hole 6 can be reduced, thereby increasing the concentration of the smoke and making the smoke fuller.
[0045] The heating part of the upper part of the double-fired ceramic heating core in the embodiment of the present application is in the shape of a rectangular parallelepiped, and the atomizing core tube 1 is a stainless steel tube with a rectangular cross-section. The stainless steel material can ensure that the atomizing core tube 1 has a good service life. The two oil inlet holes 4 of the atomizing core tube 1 are connected to the oil cup of the electronic cigarette, and the smoke in the oil cup penetrates into the oil absorption layer 2 through the oil inlet holes 4. The oil absorption layer 2 is oil absorption cotton, so that the oil absorption layer 2 can be soaked with smoke oil. The double heating wire 7 is fixed on the ceramic layer 5 by sintering, and the two conductive pins 13 at the lower part of the double-fired ceramic heating core supply power to the double heating wire 7. The cross-section of the inner hole 6 of the internal ceramic layer 5 is rectangular, and the inner hole 6 serves as an atomizing chamber. The double heating wires 7 on the two opposite inner side walls of the inner hole 6 will heat the ceramic layer 5 at the same time, so that the ceramic layer 5 can quickly heat up and atomize the smoke oil. The smoke diffuses from the micropores of the ceramic layer 5 into the inner hole 6 and is transported to the mouthpiece through the airway.
[0046] The embodiment of the present application also provides an electronic cigarette, including an oil cup, a heating core, a mouthpiece, and a power supply. The oil cup contains smoke oil that penetrates into the heating core. The heating core is arranged in an atomization chamber that communicates with the mouthpiece through an airway and is electrically connected to the power supply. The heating core is the above-mentioned double-fired ceramic heating core. The double-fired ceramic heating core adopts a parallel double heating wire 7 design. The double heating wire 7 with a larger heating area quickly atomizes the smoke oil and transports it from the inner hole 6 of the ceramic layer 5 and the airway to the mouthpiece for the user to inhale. The smoke is fuller and has a higher explosive power. At the same time, the taste of the smoke is still delicate. The double-fired ceramic heating core can be matched with an oil cup with a larger capacity to extend the use time of the cigarette cartridge.
[0047] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
