Description

Atomizer core with flat wall Technical Field

[0001] The utility model relates to the technical field of atomizing cores of electronic cigarette atomizers, and more particularly to an atomizing core with a plane wall portion. Background Art

[0002] Electronic vaping devices typically consist of a battery pack and an atomizer. The battery pack includes the battery that powers the atomizer, which houses an atomizer core. When powered, the core heats and vaporizes the atomized liquid, producing an aerosol for the user to inhale. The atomizer core of existing electronic vaping devices primarily consists of a liquid guide and a heating element. The liquid guide can be made of a liquid-conducting sponge or porous ceramic structure.

[0003] The Chinese patent document with publication number CN217771479U discloses a tubular atomizer core, including an atomizer tube, liquid-conducting cotton, a heating sheet and a hollow tube plug. The heating sheet is composed of a sheet-shaped heating resistor with a conductive path. Resistor leads are connected on both sides of the heating sheet. The heating sheet is rolled into a tube shape with no connection on both sides. The outer wall of the heating sheet is wrapped with liquid-conducting cotton and then sleeved on the middle part of the inner wall of the atomizer tube. An inverted U-shaped notch is provided on the tube wall of the atomizer tube. The hollow tube plug is sleeved on the inner and outer walls of the lower end of the atomizer tube. The wall of the hollow tube plug sleeved on one side of the inner wall of the atomizer tube abuts upward and supports the liquid-conducting cotton. The heating sheet of the atomizer core forms a circular cross-section after being rolled into a tube, that is, the cross-sectional area of ​​air circulation will be much smaller than the area of ​​a rectangle with its radius as width and its perimeter as length, so its atomization amount is relatively small and the atomization efficiency is relatively low. In addition, the liquid-conducting cotton and the heating plate of the atomizer core need to be rolled into a tube during production. In order to make the liquid-conducting cotton and the heating plate fit together, the liquid-conducting cotton and the heating plate need to be shaped. However, the shaping requires manual operation, which makes the assembly complicated and the production efficiency low, and it is not easy to achieve automated production. In addition, after the liquid-conducting cotton and the heating plate are rolled into a tube, a U-shaped notch is required on the atomizer tube for easy installation. The U-shaped notch is difficult to process, which increases the processing cost of the atomizer tube, and the U-shaped notch has a poor sealing problem, which easily leads to leakage. In addition, after the heating plate is rolled into a tube, it can only be wrapped with the liquid-conducting cotton. The mesh and the pin wire have no external force support, so it is easy to deform, resulting in unreliable operation of the atomizer core. Technical issues

In the case of changing the direction and position, the above-mentioned orientation terms will also change accordingly.

[0039] The atomizing core with a planar wall portion of the present invention is used for being assembled into an electronic atomizer to absorb atomizing liquid and heat the atomizing liquid to atomize it into aerosol, aerosol or electronic cigarette smoke. Modes for Carrying Out the Invention

[0040] The present invention will be described in detail below through specific examples. Example 1

[0041] As shown in Figures 1 and 2, an atomizing core with a flat wall portion of this embodiment is provided in the atomizer, and is used to heat the atomized liquid stored in the atomizer and evaporate it into an aerosol when it is powered on and heated. The atomizing core is composed of an outer sleeve 1, an atomizing bracket 2 installed in the outer sleeve 1, a heating mesh 3 and two layers of liquid guide layers 4. Among them, the outer sleeve 1 is a rectangular tube, the atomizing bracket 2 is a rectangular hollow bracket, and the heating mesh 3 is a rectangular thin sheet-shaped heating mesh. The heating mesh 3 has impedance and can generate heat when powered on. The electrode pins 31 are fixedly arranged in parallel on both side edges of the heating mesh 3 and can support the heating mesh 3. The lead-out parts of the electrode pins 31 are used to connect the positive and negative poles of the power supply respectively.

[0042] As shown in Figures 1 to 5, the wall portion of the outer sleeve 1 is a flat plane wall portion 10, one of which is provided with a liquid inlet hole 11. The inner wall of the outer sleeve 1 is fitted with a hollow atomizer bracket 2. A heating mesh 3 is provided in the atomizer bracket 2 and is parallel to the plane wall portion 10. Electrode pins 31 are fixedly connected to the edges of both sides of the heating mesh 3. The electrode pins 31 pass through one end of the atomizer bracket 2 and extend from one end of the outer sleeve 1. The atomizer bracket 2 is also provided with a heating mesh 3. There are two flat liquid-conducting layers 4, which are tightly arranged between the heating mesh 3 and the flat wall portion 10. The liquid inlet hole 11 is directly connected to the surface of the liquid-conducting layer 4. An atomizing cavity 20 is provided on the side of the atomizing bracket 2 where the heating mesh 3 and the liquid-conducting layer 4 are not in contact. The atomizing cavity 20 is connected to both ends of the outer sleeve 1. One end of the atomizing core, that is, one end of the outer sleeve 1, constitutes the air inlet end 12, and the other end constitutes the mist outlet end 13, which is connected to the nozzle of the atomizer. The atomized liquid flows into the liquid-conducting layer 4 through the liquid inlet hole 11 and can further penetrate and conduct to the heating mesh 3. When the heating mesh 3 is energized, the atomized liquid can be heated and evaporated into an aerosol and distributed in the atomizing cavity 20. The external gas enters the atomizing cavity 20 after passing through the air inlet end 12 and carries the aerosol out of the mist outlet 13. The flow direction of the gas and aerosol is shown as the upward arrow in Figure 5.

[0043] The atomizer bracket 2 is provided with bracket end walls 21 and 22 at both ends, each of which is provided with end wall through-holes 210 and 220. The atomizer bracket 2 is provided with bracket side walls 23 on both sides perpendicular to the planar wall portion 10. The inner side of the bracket side walls 23 is provided with a flange 24 for supporting the heating mesh. The flange 24 is provided with a groove 240 for accommodating the electrode pin 31. One end of the groove 240 extends through one of the bracket end walls 21, namely the bracket end wall at the air inlet end 12, to accommodate the electrode pin 31. The flange 24 and its groove 240 facilitate supporting and securing the heating mesh 3, allowing the flat heating mesh 3 to be stretched and laid flat within the atomizer bracket 2, preventing it from loosening and deforming. The electrode pin 31 can be easily lowered into the groove 240 from the top of the atomizer bracket 2. The groove 240 clamps the electrode pin 31, thereby securing the heating mesh 3. The atomizer bracket 2 also prevents the electrode pin 31 from contacting the metal outer sleeve 1 and causing a short circuit.

[0044] As shown in Figures 6 and 7 , in other embodiments, a porous support sheet 5 is further provided between the heating mesh 3 and the liquid-conducting layer 4. The porous support sheet 5 is provided with numerous small holes 50 for allowing the atomized liquid to pass through. The porous support sheet 5 is used to support the liquid-conducting layer 4. When the liquid-conducting layer 4 is made of a soft material, the porous support sheet 5 can support the liquid-conducting layer 4 and prevent its deformation. The liquid-conducting layer 4 can also be a single layer.

[0045] This embodiment adopts a rectangular outer sleeve, especially a flat outer sleeve, so that the atomizing core becomes a flat atomizing core, which is more suitable for installation on a flat electronic cigarette atomizer. By adopting this rectangular outer sleeve, the liquid storage cavity can leave more liquid storage space in the short axis direction of its cross section.

[0046] The atomizer core of the present invention has a rectangular heating mesh, and it is installed flat on the atomizer bracket without being rolled into a circular tube, so that the atomization channel has a larger cross-sectional area, that is, compared with the circular tube, more aerosol generation, that is, atomization amount, a higher atomization efficiency, and a better smoking taste. In addition, the outer sleeve of the atomizer core is provided with a flat wall portion, the heating mesh is also flat, and a flat soft liquid guide layer is clamped between the two, so that the three can fit tightly together, and the atomized liquid can be more effectively and reliably conducted to the heating mesh through the liquid guide layer, ensuring the stability and reliability of the atomization amount. The pins of the heating mesh can be fixed in the grooves of the flange, so that the heating mesh can firmly support and support the liquid guide layer, preventing the liquid guide layer and the heating mesh from loosening and deformation, so that the atomizer core works reliably and is not prone to failure. Furthermore, both the liquid-conducting layer and the heating mesh are flat blocks that can be directly mounted on the atomizer bracket without the need for rolling into a tubular shape. This eliminates the need for additional shaping during assembly and allows for direct placement and installation, resulting in precise positioning, simple and efficient assembly, and easy automated assembly to reduce costs. Furthermore, the liquid-conducting layer and the heating mesh are laid flat within the atomizer bracket and then inserted into the outer sleeve, eliminating the need for a U-shaped notch in the outer sleeve. This provides a better seal and reduces the risk of leakage. Furthermore, the outer sleeve is easy to manufacture, reducing processing costs.

[0047] In an embodiment of the present invention, the outer sleeve can be made of a metal material. Since the outer sleeve is generally immersed in the atomized liquid, the outer sleeve made of the metal material can absorb the excess heat of the heating mesh and conduct it to the atomized liquid, so that the temperature of the atomized liquid increases during use and is preheated, and it can better have fluidity and conductive permeability, thereby improving the atomization efficiency. The atomization bracket can be made of a silicone material that is resistant to the high temperature of the atomizer core. The silicone material has the property of being resistant to high temperature and not deforming. It is not easy to be deformed by high temperature during the operation of the atomizer core, and it will not decompose and produce harmful substances during high temperature operation. The liquid guide layer can be made of a porous ceramic material or a cotton material. The cotton material has good atomized liquid conductivity. The cotton material includes at least one of organic cotton, ceramic fiber cotton, glass fiber cotton, PP fiber, nylon fiber, non-woven fabric, or PET fiber. Example 2

[0048] As shown in Figures 8-13, based on Example 1, the atomizer core of this embodiment has a planar wall portion. A sealing sleeve 6 is provided on the inner wall of the mist outlet end 13 of the outer sleeve 1. The sealing sleeve 6 has a mist outlet hole 60. The inner end of the sealing sleeve 6, which is located within the outer sleeve 1, abuts against the atomizer bracket 2. The outer end of the sealing sleeve 6 has an annular groove 61, and the tube wall of the outer sleeve 1 is inserted into the annular groove 61. The mist outlet hole 60 is used to connect to the inlet pipe of the atomizer.

[0049] The air inlet end of the outer sleeve 1 is also connected to an atomizer seat 7. The center of the atomizer seat 7 is provided with an air inlet hole 70. The air inlet end of the outer sleeve 1 is plugged into the upper half of the air inlet hole 70. The lower half of the atomizer seat 7 is provided with electrode insertion holes 71 on both sides of the air inlet hole 70. The lower half of the atomizer seat 7 is provided with two protrusions 72, and the electrode insertion holes 71 are provided within the protrusions 72. The electrode insertion holes 71 are used to lead out the electrode pins 31 and to insert the electrode column to achieve electrical connection with the electrode pins 31. The other two sides of the air inlet hole 70 are also provided with atomizing liquid filling holes 73 for injecting atomizing liquid into the atomizer when assembling the atomizer. Example 3

[0050] As shown in Figures 14-17 , the atomizer core of this embodiment, which has a planar wall, is composed of an outer sleeve 1, an atomizer bracket 2, two heating mesh sheets 3, and four liquid guide layers 4. The outer sleeve 1 is a rectangular tube, the atomizer bracket 2 is a rectangular hollow bracket, and the heating mesh sheets 3 are rectangular heating mesh sheets. Electrode pins 31 are fixedly mounted parallel to and support the two side edges of the heating mesh sheets 3.

[0051] The wall portion of the outer sleeve 1 is a flat plane wall portion 10, wherein two opposite plane walls 10 are provided with liquid inlet holes 11 respectively. The inner wall of the outer sleeve 1 is fitted with a hollow atomizing bracket 2, and two heating meshes 3 parallel to the plane wall portion 10 are provided in the atomizing bracket 2. Electrode pins 31 are provided on both sides of each heating mesh 3, which pass through one end of the atomizing bracket 2 and extend from one end of the outer sleeve 1. Two layers of liquid guide layers 4 are provided on each heating mesh 3 in the atomizing bracket 2. The liquid guide layer 4 is tightly arranged between the heating mesh 3 and the plane wall portion 10. The liquid inlet holes 11 are directly connected to the surface of the liquid guide layer 4. An atomizing cavity 20 is provided in the atomizing bracket 2 on the side where the heating mesh 3 and the liquid guide layer 4 are not in contact, that is, two heating meshes 3 are provided. An atomizing cavity 20 is provided between the sheets 3, and the atomizing cavity 20 is respectively connected to the two ends of the outer sleeve 1. One end of the outer sleeve 1 constitutes the air inlet end 12, and the other end constitutes the mist outlet end 13. The atomized liquid flows into the liquid guide layer 4 through the liquid inlet hole 11 and further penetrates and conducts to the heating mesh 3. When the heating mesh 3 is energized, the atomized liquid can be heated and evaporated into aerosol and emitted in the atomizing cavity 20. The external gas enters the atomizing cavity 20 after passing through the air inlet end 12 and is discharged from the mist outlet end 13 carrying the aerosol.

[0052] The two ends of the atomizer bracket 2 are provided with bracket end walls 21 and 22, and the bracket end walls 21 and 22 are provided with end wall through holes 210 and 220. The atomizer bracket 2 is provided with bracket side walls 23 on both sides perpendicular to the plane wall portion 10. The inner side of the bracket side wall 23 is longitudinally provided with a flange 24 for supporting the heating mesh. The flange 24 is provided with a groove 240 for accommodating the electrode pin 31. One end of the groove 240 passes through one of the bracket end walls 21 to install the electrode pin 31. The flange 24 and its groove 240 facilitate supporting and fixing the heating mesh 3, so that the flat heating mesh 3 can be stretched and laid flat in the atomizer bracket 2 to prevent it from loosening and deforming. The groove 240 can clamp and fix the electrode pin of the heating mesh, and can also prevent the electrode pin from contacting the outer sleeve 1 made of metal material and causing a short circuit.

[0053] This embodiment adopts a rectangular outer sleeve, especially a flat outer sleeve, so that the atomizing core becomes a flat atomizing core, which is more suitable for installation on a flat electronic cigarette atomizer. By adopting this rectangular outer sleeve, the liquid storage cavity can leave more liquid storage space in the short axis direction of its cross section.

[0054] This embodiment uses two heating meshes working simultaneously, which can increase the amount of aerosol generated per unit time, that is, the amount of atomization, improve the atomization efficiency, and enhance the smoking taste.

[0055] The atomizer core of the present invention has a rectangular heating mesh, and it is installed flat on the atomizer bracket without being rolled into a circular tube, so that the atomization channel has a larger cross-sectional area, that is, compared with the circular tube, more aerosol generation, that is, atomization amount, a higher atomization efficiency, and a better smoking taste. In addition, the outer sleeve of the atomizer core is provided with a flat wall portion, the heating mesh is also flat, and a flat soft liquid guide layer is clamped between the two, so that the three can fit tightly together, and the atomized liquid can be more effectively and reliably conducted to the heating mesh through the liquid guide layer, ensuring the stability and reliability of the atomization amount. The pins of the heating mesh can be fixed in the grooves of the flange, so that the heating mesh can firmly support and support the liquid guide layer, preventing the liquid guide layer and the heating mesh from loosening and deformation, so that the atomizer core works reliably and is not prone to failure. Furthermore, both the liquid-conducting layer and the heating mesh are flat blocks that can be directly mounted on the atomizer bracket without the need for rolling into a tubular shape. This eliminates the need for additional shaping during assembly and allows for direct placement and installation, resulting in precise positioning, simple and efficient assembly, and easy automated assembly to reduce costs. Furthermore, the liquid-conducting layer and the heating mesh are laid flat within the atomizer bracket and then inserted into the outer sleeve, eliminating the need for a U-shaped notch in the outer sleeve. This provides a better seal and reduces the risk of leakage. Furthermore, the outer sleeve is easy to manufacture, reducing processing costs.

Electrode pins 31 are provided on both side edges of each heating mesh 3. The electrode pins 31 pass through one end of the atomizing bracket 2 and extend from one end of the outer sleeve 1. Two layers of liquid guiding layers 4 are also provided on the heating mesh 3. The liquid guiding layers 4 are tightly arranged between the heating mesh 3 and the plane wall portion 10. The liquid inlet hole 11 is directly connected to the surface of the liquid guiding layer 4. The central part surrounded by the three heating meshes 3 constitutes an atomizing cavity 20. The atomizing cavity 20 is respectively connected to the two ends of the outer sleeve 1. One end of the outer sleeve 1 constitutes the air inlet end 12, and the other end constitutes the mist outlet end 13. The atomized liquid flows into the liquid guiding layer 4 through the liquid inlet hole 11 and further penetrates and conducts to the heating mesh 3. When the heating mesh 3 is energized, the atomized liquid can be heated and evaporated into an aerosol. The aerosol is emitted in the atomizing cavity 20. The external gas enters the atomizing cavity 20 after passing through the air inlet end 12 and is discharged from the mist outlet end 13 carrying the aerosol.

[0059] The atomizer bracket 2 is provided with bracket end walls 21 and 22 at both ends, and the bracket end walls 21 and 22 are provided with end wall through holes 210 and 220. The atomizer bracket 2 is provided with bracket side walls 23 on both sides perpendicular to the plane wall portion 10. The inner side of the bracket side wall 23 is longitudinally provided with a flange 24 for supporting the heating mesh. The flange 24 is provided with a groove for accommodating the electrode pin 31, and one end of the groove passes through one of the bracket end walls 21 to install the electrode pin 31.

[0060] This embodiment adopts a triangular outer sleeve and uses three heating meshes to work simultaneously, which can increase the aerosol generation amount per unit time, that is, the atomization amount, improve the atomization efficiency, and enhance the smoking taste.

[0061] The atomizer core of this embodiment has a flat wall portion and a rectangular heating mesh, which is installed flat on the atomizer bracket without being rolled into a circular tube shape, so that the atomizer channel has a larger cross-sectional area. That is, compared with the circular tube shape, more aerosol generation, i.e., atomization amount, a higher atomization efficiency, and a better smoking taste can be obtained.

[0062] The outer sleeve of the atomizer core features a flat wall, and the heating mesh is also flat. A flat, soft liquid-conducting layer is sandwiched between the two, ensuring a tight fit. The atomized liquid is more effectively and reliably transferred to the heating mesh through the liquid-conducting layer, ensuring a stable and reliable atomization rate. The heating mesh's pins can be fixed within the grooves of the flange, firmly supporting and holding the liquid-conducting layer, preventing the liquid-conducting layer and the heating mesh from loosening or deforming, ensuring reliable operation and less prone to malfunction.

[0063] In addition, the liquid guide layer and the heating mesh are both in the form of flat blocks, which can be directly accommodated and installed on the atomizer bracket without being rolled into a tube, so that no additional shaping is required during assembly. They can be directly placed and installed, with accurate positioning, simple and efficient assembly, and easy automated assembly to reduce costs.

[0064] In addition, the liquid guide layer and the heating mesh are laid flat in the atomizer bracket and then inserted into the outer tube, so the outer tube does not need to have a U-shaped notch, so that the outer tube has a better sealing effect and is not prone to leakage. The outer tube is easy to process and can reduce processing costs.

[0065] In an embodiment of the present invention, the outer sleeve can be made of a metal material. Since the outer sleeve is generally immersed in the atomized liquid, the outer sleeve made of the metal material can absorb the excess heat of the heating mesh and conduct it to the atomized liquid, so that the temperature of the atomized liquid increases during use and is preheated, and it can better have fluidity and conductive permeability, thereby improving the atomization efficiency. The atomization bracket can be made of a silicone material that is resistant to the high temperature of the atomizer core. The silicone material has the property of being resistant to high temperature and not deforming. It is not easy to be deformed by high temperature during the operation of the atomizer core, and it will not decompose and produce harmful substances during high temperature operation. The liquid guide layer can be made of a porous ceramic material or a cotton material. The cotton material has good atomized liquid conductivity. The cotton material includes at least one of organic cotton, ceramic fiber cotton, glass fiber cotton, PP fiber, nylon fiber, non-woven fabric, or PET fiber. Industrial Applicability
