Description

Atomizer with a flat liquid-conducting layer Technical Field

The present invention relates to the technical field of electronic cigarettes, and more particularly, to an atomizer having a flat liquid-conducting layer.

Background Art

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.

The Chinese patent document with publication number CN217771478U discloses an electronic cigarette with a tubular atomization core, including a mouthpiece, a shell, a base, and a battery assembly and an atomization assembly arranged in the shell. The mouthpiece is arranged at the upper end of the shell, and the base is arranged at the lower end of the shell. The battery assembly includes a battery and an airflow sensor. The atomization assembly includes a tubular atomization core, and the tubular atomization core includes an atomization tube, liquid guide cotton, a heating plate and a hollow tube plug. The heating plate is composed of a sheet heating resistor with a conductive path. Resistance leads are connected on both sides of the heating plate. The heating plate is rolled into a tube with no connection on both sides. The outer wall of the heating plate is wrapped with liquid guide cotton and then mounted on the middle part of the inner wall of the atomization tube. An inverted U-shaped notch is provided on the tube wall of the atomization tube. The hollow tube plug is sleeved on the lower end of the atomization tube, and the inner wall of the hollow tube plug supports the liquid guide cotton upward. The atomizer core of this atomizer has a circular cross-section after its heating plate is rolled into a tube, that is, the cross-sectional area of air circulation will be much smaller than the rectangular area 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, and 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 for easy installation, a U-shaped notch is also required on the atomizer tube. The U-shaped notch is difficult to process, which increases the processing cost of the atomizer tube, and the U-shaped notch has the problem of poor sealing, which easily leads to leakage. In addition, after the heating plate is rolled into a tube, it can only rely on the liquid-conducting cotton to wrap, and its mesh and pin wires have no external force support, so it is easy to deform, resulting in unreliable operation of the atomizer core and malfunction.

The air inlet end 12 of the atomizer core is plugged into the upper half of the air inlet hole of the atomizer seat. The lower half of the atomizer seat is located on both sides of the air inlet hole of the atomizer seat and is provided with electrode plug-in blind holes.

As shown in Figures 7-9, the air inlet end of the outer sleeve 1 is also connected to an atomizer seat 300. The center of the atomizer seat 300 is provided with an atomizer seat air inlet hole 301. The air inlet end 12 of the atomizer core is plugged into the upper half of the atomizer seat air inlet hole 301. The lower half of the atomizer seat 300 is located on both sides of the atomizer seat air inlet hole 301 and is further provided with electrode plug-in blind holes 303.

The electrode column is provided on the base 400. Atomizing liquid injection holes 304 are provided on the other two sides of the atomizing seat air inlet hole 301 . The injection holes 304 are used to inject atomizing liquid when assembling the atomizer. A plunger 402 is protruding from the base 400 to block the injection holes 304 .

As shown in Figures 10 to 14, the atomizer core 200 of this embodiment 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 atomizer core 200 is composed of an outer sleeve 1, an atomizer bracket 2 installed in the outer sleeve 1, a heating mesh 3 and two flat liquid guide layers 4. Among them, the outer sleeve 1 is a rectangular tube, the atomizer bracket 2 is a rectangular hollow bracket, and the heating mesh 3 is a rectangular thin sheet 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.

The wall of the outer tube 1 is a flat plane wall 10, one of which is provided with a liquid inlet hole 11. The inner wall of the outer tube 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 10. The two sides of the heating mesh 3 are fixedly connected with electrode pins 31. The electrode pin 31 passes through one end of the atomizer bracket 2 and extends from one end of the outer tube 1. The atomizer bracket 2 is also provided with two flat liquid guide layers. 4. The liquid-conducting layer 4 is 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-conducting layer 4. An atomizing cavity 20 is provided in the atomizing bracket 2 on the side where the heating mesh 3 and the liquid-conducting layer 4 do not contact. The atomizing cavity 20 is part of the straight airway 700. The atomizing cavity 20 is connected to both 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 mist outlet end 13 is connected to the mouthpiece 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 to be discharged from the mist outlet end 13. The flow direction of the gas and aerosol is as shown by the upward arrow in Figure 5.

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 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.

As shown in Figures 15 and 16 , 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 passing the atomized liquid. 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.

The embodiment of the present invention provides an atomizer with a flat liquid-conducting layer, wherein the atomizer core adopts a rectangular outer sleeve, especially a flat outer sleeve, so that the atomizer core becomes a flat atomizer core, which is more suitable for installation on a flat electronic cigarette atomizer. By adopting the rectangular outer sleeve, the liquid storage cavity can reserve more liquid storage space in the short axis direction of its cross section.

The atomizer core 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 groove 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 them into a tubular shape. This eliminates the need for additional shaping during assembly and allows for direct placement and installation, resulting in accurate positioning, simple and efficient assembly, and easy automated assembly to reduce costs. Furthermore, the soft liquid-conducting layer and heating mesh can be 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.

The outer sleeve of the atomizer core in the embodiment of the present invention can be made of a metal material. Since the outer sleeve is generally immersed in the atomized liquid, the metal outer sleeve can absorb excess heat from the heating mesh and transfer it to the atomized liquid, causing the atomized liquid to heat up during use and preheat. This improves fluidity and conductivity, thereby enhancing atomization efficiency. The atomizer bracket can be made of a silicone material that is resistant to the high temperatures of the atomizer core. Silicone material has the properties of high temperature resistance and does not deform during operation due to high temperatures. It is not easily deformed by high temperatures during atomizer core operation and does not decompose to produce harmful substances during high temperature operation. The liquid guide layer can be made of a porous ceramic material or a soft material. The soft material can be cotton material, which has excellent atomized liquid conductivity. Cotton materials include at least one of organic cotton, ceramic fiber cotton, glass fiber cotton, PP fiber, nylon fiber, non-woven fabric, or PET fiber.

Example 2:

As shown in Figures 17-20, the embodiment of the present invention has an atomizer with a flat liquid-conducting layer. Based on the first embodiment, it mainly adopts another atomizer core 200. The atomizer core 200 is composed of an outer sleeve 1, an atomizer bracket 2, two heating mesh sheets 3, and four layers of liquid-conducting layers 4. Among them, the outer sleeve 1 is a rectangular tube, the atomizer bracket 2 is a rectangular hollow bracket, and the heating mesh sheet 3 is a rectangular heating mesh sheet. The electrode pins 31 are fixedly arranged parallel to the two side edges of the heating mesh sheet 3 and can support the heating mesh sheet 3.

The wall portion of the outer sleeve 1 is a flat-plate-shaped plane wall portion 10, wherein two opposite plane walls 10 are respectively provided with liquid inlet holes 11. 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 respectively 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, between the two heating meshes 3. An atomizing cavity 20 is provided in the middle, and the atomizing cavity 20 is respectively connected with 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. 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.

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.

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

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.

Similarly, the atomizer of this embodiment has an atomizer core with 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, atomization efficiency is higher, and the smoking taste is better. 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 sandwiched 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 groove of the flange, and the heating mesh can be firmly supported and supported by 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 them into a tubular shape. This eliminates the need for additional shaping during assembly and allows for direct placement and installation, resulting in accurate positioning, simple and efficient assembly, and easy automated assembly to reduce costs. Furthermore, the soft liquid-conducting layer and heating mesh can be 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.

The outer sleeve of the atomizer core in the embodiment of the present invention can be made of a metal material. Since the outer sleeve is generally immersed in the atomized liquid, the metal outer sleeve can absorb excess heat from the heating mesh and transfer it to the atomized liquid, causing the atomized liquid to heat up during use and preheat. This improves fluidity and conductivity, thereby enhancing atomization efficiency. The atomizer bracket can be made of a silicone material that is resistant to the high temperatures of the atomizer core. Silicone material has the properties of high temperature resistance and does not deform during operation due to high temperatures. It is not easily deformed by high temperatures during atomizer core operation and does not decompose to produce harmful substances during high temperature operation. The liquid guide layer can be made of a porous ceramic material or a soft material. The soft material can be cotton material, which has excellent atomized liquid conductivity. Cotton materials include at least one of organic cotton, ceramic fiber cotton, glass fiber cotton, PP fiber, nylon fiber, non-woven fabric, or PET fiber.

Example 3:

As shown in Figures 21 to 25, the embodiment of the present invention has an atomizer with a flat liquid-conducting layer. On the basis of the second embodiment, another atomizer core 200 is mainly used. The atomizer core 200 is composed of an outer sleeve 1, an atomizer bracket 2, three heating meshes 3 and 6 layers of liquid-conducting layers 4. Among them, the outer sleeve 1 is a triangular or roughly triangular tube, the atomizer bracket 2 is a triangular or roughly triangular hollow bracket, and the three plane walls 10 of the outer sleeve 1 are respectively provided with liquid inlet holes 11. The heating mesh 3 is a rectangular heating mesh. The electrode pins 31 are fixedly arranged in parallel on the two side edges of the heating mesh 3 and can support the heating mesh 3. Each heating mesh 3 is respectively provided with two layers of liquid-conducting layers 4.

The three walls of the triangular rhombus of the outer sleeve 1 are all flat planar walls 10, wherein each planar wall 10 is respectively provided with a liquid inlet hole 11, and the inner wall of the outer sleeve 1 is fitted with a hollow atomizer bracket 2, and the atomizer bracket 2 is provided with a heating mesh 3 parallel to the planar wall 10, and the three heating meshes 3 are also arranged in a triangular rhombus shape. 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.

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.

As shown in Figure 26, the atomizer seat 300 of this embodiment has an atomizer seat air inlet hole 301 extending vertically through the center. The air inlet end 12 of the atomizer core is plugged into the upper half of the atomizer seat air inlet hole 301. The lower half of the atomizer seat 300 is also provided with electrode insertion slots 303 on both sides of the atomizer seat air inlet hole 301. The lower half of the atomizer seat 300 is provided with a raised portion 302, and electrode insertion slots 303 are provided on both sides of the raised portion 302. The electrode insertion slots 303 are used to insert electrode posts for electrical connection with electrode pins 31. The electrode posts are provided on the base 400. Atomizer seat air inlet hole 301 is also provided with atomizer liquid injection holes 304 on the other two sides. The injection holes 304 are used to inject atomizer liquid when assembling the atomizer. The base 400 is provided with a plug protruding from the injection holes 304 to block the injection holes 304.

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.

Similarly, the atomizer of this embodiment has an atomizer core with 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, atomization efficiency is higher, and the smoking taste is better. 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 sandwiched 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 groove of the flange, and the heating mesh can be firmly supported and supported by 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 them into a tubular shape. This eliminates the need for additional shaping during assembly and allows for direct placement and installation, resulting in accurate positioning, simple and efficient assembly, and easy automated assembly to reduce costs. Furthermore, the soft liquid-conducting layer and heating mesh can be 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.

The outer sleeve of the atomizer core in the embodiment of the present invention can be made of a metal material. Since the outer sleeve is generally immersed in the atomized liquid, the metal outer sleeve can absorb excess heat from the heating mesh and transfer it to the atomized liquid, causing the atomized liquid to heat up during use and preheat. This improves fluidity and conductivity, thereby enhancing atomization efficiency.
