Description

Technical Field

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

[0002] Electronic atomization equipment generally includes a battery assembly and an atomizer. The battery assembly includes a battery that supplies power to the atomizer. The atomizer is provided with an atomizer core. When powered on, the atomizer core can heat and evaporate the atomized liquid to generate aerosol for the user to inhale. The atomizer core of existing electronic atomization equipment mainly includes a liquid guide and a heating element. The liquid guide includes a liquid guide cotton or a porous ceramic structure.

[0003] The Chinese patent document with the publication number CN217771479U discloses a tubular atomization core, including an atomization 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. The two sides of the heating sheet are connected with resistor leads. 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 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 inner wall and outer wall of the lower end of the atomization tube. The wall of the hollow tube plug sleeves on one side of the inner wall of the atomization tube upwardly abuts and supports the liquid-conducting cotton. The heating sheet of the atomization 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 rectangular area with its radius as the width and its perimeter as the length, so its atomization amount is relatively small and the atomization efficiency is relatively low. In addition, the liquid-conducting cotton and the heating sheet of the atomizer core need to be rolled into a tube during production. In order to make the liquid-conducting cotton and the heating sheet fit together, the liquid-conducting cotton and the heating sheet need to be shaped. However, 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 sheet 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 sheet is rolled into a tube, it can only be wrapped with the liquid-conducting cotton, 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.

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.

[0064] This embodiment adopts a triangular outer sleeve and uses three heating meshes to work 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.

[0065] The atomizer core of this embodiment has a flat wall portion and a rectangular heating mesh, and 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, i.e., atomization amount, a higher atomization efficiency, and a better smoking taste can be obtained.

[0066] In addition, the outer sleeve of the atomizer core is provided with a flat wall portion, the heating mesh is also in a flat shape, 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 firmly support and hold the liquid guide layer, preventing the liquid guide layer and the heating mesh from loosening and deforming, so that the atomizer core can work reliably and not easily fail.

[0067] 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 in and installed, with accurate positioning, simple and efficient assembly, and easy automated assembly to reduce costs.

[0068] In addition, the liquid guide layer and the heating mesh are laid flat in the atomizer bracket and then inserted into the outer sleeve, so the outer sleeve does not need to have a U-shaped notch, so that the outer sleeve has a better sealing effect and is not easy to cause leakage. The outer sleeve is easy to process and can reduce the processing cost.

[0069] In an embodiment of the utility model, 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 is increased during use and 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 atomization core. The silicone material has the performance of high temperature resistance and non-deformation. It is not easy to deform due to high temperature during the operation of the atomization 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 conduction performance. 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.

[0070] The above description is only a preferred embodiment of the utility model, and the above specific embodiment is not a limitation of the utility model. Various deformations and modifications may occur within the technical concept of the utility model, and any modification, modification or equivalent replacement made by ordinary technicians in this field based on the above description belongs to the scope of protection of the utility model.
