Description

Technical Field

[0001] The utility model belongs to the technical field of atomizer cores of electronic atomizers, and particularly relates to an atomizer core with multiple heating areas. Background Art

[0002] The atomizing core of the electronic atomizer is used to heat the liquid to be atomized, i.e., the atomizing liquid, and atomize it into an aerosol or steam, vapor mist or smoke for the user to inhale. The atomizing liquid can be a cigarette liquid or a solution containing herbal essence or medicine for health and medical purposes. The electronic atomizer can be used for electronic cigarettes.

[0003] The current atomizer core of the electronic atomizer includes a porous ceramic matrix as a liquid guide, and there are many micropores on the liquid guide for infiltration, absorption and conduction of the atomized liquid. The liquid guide is fitted with heating elements such as heating wires, heating sheets, and heating films. The heating elements are powered on to heat the atomized liquid on the liquid guide and atomize it into an aerosol or steam, vapor mist or smoke. The liquid guide of the existing atomizer core includes a liquid inlet surface and an atomizing surface. There is only one heating area on the atomizing surface. When it is powered on and heated, the heating area of ​​the heating area is fixed. After working for a long time, the micropores on the surface of the heating area are easily blocked by solid matter or carbon deposits in the atomized liquid, resulting in less and less atomized liquid seeping out of the atomizing surface, resulting in insufficient liquid supply, a reduced taste of the user, and inconsistent inhalation experience. In addition, there is only one heating area on the atomization surface, and the heating area is fixed. Its heating power is difficult to make a significant adjustment, so the atomization amount of aerosol or mist produced cannot be adjusted significantly or in steps. The user's smoking taste can only remain unchanged, and the user cannot get the experience of a variety of different smoke amounts. Utility Model Content

[0004] The technical problem solved by the utility model is to overcome the deficiencies of the prior art and provide an atomizer core with multiple heating areas and an atomizer core thereof.

[0005] The technical solution of the utility model is an atomization core with multiple heating areas, including a porous liquid-conducting liquid and a heating layer and an electrode layer arranged on the porous liquid-conducting liquid. The porous liquid-conducting liquid is provided with many micropores for penetrating and conducting atomized liquid. The porous liquid-conducting liquid is a polyhedron, one side of which is an atomizing surface, and at least one other side is a liquid inlet surface. The atomizing surface is divided into at least two heating areas and a plurality of conductive areas, a heating area is provided between every two conductive areas, the heating layer is provided on the surface of the heating area, and the electrode layer is provided on the surface of the conductive area.

[0006] Preferably, the conductive area and the heating area are laterally arranged on the atomization surface in sequence and at intervals, and there is at least one more conductive area than the heating area.

[0011] Preferably, the atomization surface is divided into two heating areas and three conductive areas.

[0012] Preferably, the two heating areas are laterally arranged between two of the three conductive areas, respectively, wherein the electrode layer provided on the middle conductive area is a common electrode layer for the two heating layers.

[0013] Preferably, the two heating areas are arranged in the middle of the atomizing surface and are separated from each other, one of the conductive areas is arranged on the atomizing surface on one side of the two heating areas and is respectively connected to the two heating areas, and the other two conductive areas are respectively arranged on the atomizing surface on the other side of the two heating areas and are respectively connected to the two heating areas.

[0014] Preferably, the atomization surface is divided into three heating areas and four conductive areas.

[0015] Compared with the prior art, the beneficial effect of the atomizer core of the utility model is that at least two heating areas and multiple conductive areas are divided on the same atomization surface of the atomizer core, and each heating area is provided with a heating layer that can work independently. By controlling the power supply of each heating layer, the working switching between the heating layers can be realized, and the switching of one heating layer working alone or multiple heating layers working together can be realized. When each heating layer is switched under the condition of working alone, the continuous working time and the cumulative working time of each heating layer can be shortened, so that its workload can be reduced, and the condition that the micropores on the surface of each heating area are blocked by solid substances or carbon deposits in the atomized liquid can be alleviated, and the working life of the entire atomization surface can be greatly extended, avoiding insufficient liquid supply caused by micropore blockage, ensuring that the user has a good inhalation taste, and maintaining a consistent inhalation experience. When switching under the condition of one heating layer working alone or multiple heating layers working together, the heating area can be greatly increased or decreased as needed, and the atomization amount of aerosol or aerosol generated by the atomizer core can be greatly adjusted, so that the user can obtain a variety of different smoke volumes. In addition, since each heating layer can be automatically switched, when a heating layer fails, it can be switched to the remaining heating layers to continue working without affecting the overall performance.

[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] In order to facilitate the description and better illustrate the utility model and its embodiments, the terms or descriptions indicating direction or position relationship such as "upper", "lower", "lateral", "length" and "width" in this document all refer to the direction or position of the device or element in the drawings, and are not used to limit the indicated device, element or component to have a specific orientation, or to be constructed and operated in a specific orientation. When the direction and position are changed, the above-mentioned orientation terms will also change accordingly.

[0024] The utility model has an atomizer core with multiple heating areas, wherein multiple heating areas refer to two or more heating areas.

[0025] The present invention will be further described in detail below with reference to the embodiments:

[0026] Embodiment 1

[0027] like Figure 1 As shown, the utility model has an atomizer core with multiple heating areas, which is composed of a porous liquid-conducting liquid 1 and a plurality of heating layers 2 and a plurality of electrode layers 3 arranged on the porous liquid-conducting liquid 1. The heating layer 2 can be energized to generate heat, and the electrode layer 3 can serve as the positive electrode or negative electrode of the heating layer 2 and be connected to the positive electrode or negative electrode of the power supply.

[0028] like Figure 2As shown, there are many micropores in the porous liquid-conducting body 1 for infiltrating and conducting the atomized liquid. The micropores are bubble-shaped micropores or other irregular micropores. Because their pore diameters are micrometers or nanometers and are too small, they cannot be illustrated in the figure. The porous liquid-conducting body 1 is a rectangular polyhedron, the lower plane of which is the liquid inlet surface, and the upper plane is the atomization surface. The atomized liquid can enter from the liquid inlet surface and then penetrate and conduct to the atomization surface. Two heating areas 21, 22 and three conductive areas 31, 32, 33 are divided on the same atomization surface. The two heating areas are respectively arranged horizontally between the three conductive areas, and the electrode layer 2 laid on the middle conductive area 32 is a common electrode layer of the two heating layers. That is, there is a heating area between every two conductive areas, and the surface of each heating area 21, 22 is laid with a heating layer 2 that can work independently, and the surface of each conductive area 31, 32, 33 is laid with an electrode layer 3. In this embodiment, the conductive areas 31, 32, 33 and the heating areas 21, 22 are arranged on the atomizing surface in a sequentially spaced manner, that is, the atomizing surface is divided into the conductive area 31, the heating area 21, the conductive area 32, the heating area 22 and the conductive area 33 in a sequentially spaced manner, and the conductive area is one more than the heating area. In such a structure, the electrode layer 3 is connected to both sides of each heating layer 2. When the electrode layers 3 on both sides of the heating layer 2 are respectively connected to the positive and negative poles of the power supply, the heating layer 2 can be powered on and heated. The resistance of the electrode layer 3 is extremely small, and it only conducts electricity as an electrode without generating heat. When the heating layer 2 is powered on and heated, the atomized liquid that has been stored and conducted to the atomizing surface, in contact with or adjacent to the heating layer can be heated and atomized into steam or vapor mist or aerosol. In this embodiment, the electrode layer 3 of the conductive area 31 can be used as a common electrode such as a positive electrode for the heating layer 2 of the adjacent heating areas 21 and 22, while the electrode layers 3 of the conductive areas 31 and 33 at the other two ends are respectively used as another electrode such as a negative electrode for the heating layer 2 of the adjacent heating areas 21 and 22.

[0029] The heating layer 2 is an independently working heating layer, so that by controlling the power supply of each heating layer 2, the working switching between the heating layers 2 can be realized, and the switching between one heating layer 2 working alone or multiple heating layers 2 working together can be realized. The switching can be automatically switched according to a preset program, or manually switched according to user needs.

[0030] When the individual working of each heating layer 2 is switched, the continuous working time and the cumulative working time of each heating layer 2 can be shortened, which can reduce its workload, so that the condition in which the micropores on the surface of each heating area 21, 22 are blocked by solid substances or carbon deposits in the atomized liquid can be alleviated, and the working life of the entire atomization surface can be greatly extended, avoiding insufficient liquid supply due to micropore blockage, ensuring that users have a good inhalation taste and maintaining a consistent inhalation experience.

[0031] When switching between one heating layer 2 working alone or multiple heating layers 2 working together, the heating area can be greatly increased or decreased, and the atomization amount of aerosol or mist generated by the atomization core can be greatly adjusted, so that the user can obtain a variety of usage experiences with different smoke amounts.

[0032] In addition, since each heating layer 2 can be automatically switched, when a heating layer 2 fails, it can automatically switch to the remaining heating layers 2 to continue working without affecting the overall performance of the atomizer core.

[0033] In this embodiment, the porous liquid-conducting body 1 is a porous ceramic body sintered at high temperature, and in other embodiments it may be a porous silicon crystal or the like.

[0034] In this embodiment, the heating layer 2 is a metal film layer formed by coating the metal on the surface of the heating areas 21 and 22 through a PVD sputtering process. In other embodiments, the heating layer 2 can also be a metal heating circuit formed by printing a metal resistor paste on the surface of the heating area and then sintering it with a conductive liquid.

[0035] In this embodiment, the electrode layer 3 is a metal thick film layer formed by printing metal paste on the surface of the conductive areas 31, 32, 33 and then sintering with the conductive liquid. In other embodiments, it can also be a metal thin sheet layer adhered and fixed to the surface of the conductive area.

[0036] Embodiment 2

[0037] This embodiment changes the distribution positions of the heating area and the conductive area based on the first embodiment.

[0038] like Figure 3 As shown, the utility model has an atomizer core with multiple heating areas, which is composed of a porous liquid-conducting liquid 1 and a heating layer 2 and an electrode layer 3 arranged on the porous liquid-conducting liquid 1. The heating layer 2 can be energized to generate heat, and the electrode layer 3 can serve as the positive electrode or negative electrode of the heating layer 2 and be connected to the positive electrode or negative electrode of the power supply.

[0039] like Figure 4 As shown, the porous liquid-conducting body 1 is provided with many micropores for infiltrating and conducting the atomized liquid. The porous liquid-conducting body 1 is a rectangular polyhedron, the lower plane of which is the liquid inlet surface, and the upper plane is the atomizing surface. The atomized liquid can enter from the liquid inlet surface and then infiltrate and conduct to the atomizing surface. Two heating areas 21, 22 and three conductive areas 31, 32, 33 are divided on the same atomizing surface. A heating area is provided between every two conductive areas. The surface of each heating area 21, 22 is provided with a heating layer 2 that can work independently, and the surface of each conductive area 31, 32, 33 is provided with an electrode layer 3.

[0040] In this embodiment, the two heating areas 21 and 22 are arranged in the middle of the atomizing surface, and the middle of the two heating areas 21 and 22 are separated, one of the conductive areas 33 is arranged on the atomizing surface on one side of the two heating areas 21 and 22 and connected to the two heating areas, and the other two conductive areas 31 and 32 are respectively arranged on the atomizing surface on the other side of the two heating areas 21 and 22 and are respectively connected to the two heating areas. That is, the two heating areas 21 and 22 are arranged on both sides of the width direction of the middle part of the atomizing surface, and the middle of the two heating areas are separated, one conductive area 33 is arranged on one side of the length direction of the atomizing surface and is respectively connected to the two heating areas 21 and 22, and the other two conductive areas 31 and 32 are respectively arranged on the other side of the length direction of the atomizing surface and are separated in the middle, and the two conductive areas 31 and 32 are respectively connected to the two heating areas 21 and 22. In such a structure, the two heating layers 2 are independent of each other, and both sides of each heating layer 2 are connected with an electrode layer 3. When the electrode layers 3 on both sides of the heating layer 2 are respectively connected to the positive and negative poles of the power supply, the heating layer 2 can be powered on to generate heat. The resistance of the electrode layer 3 is extremely small, and it only conducts electricity as an electrode without generating heat. When the heating layer 2 is powered on to generate heat, the atomized liquid that has been stored and conducted to the atomization surface, in contact with or adjacent to the heating layer can be heated and atomized into steam, vapor mist or aerosol. In this embodiment, the electrode layer 3 of the conductive area 33 can be used as a common electrode, such as a positive electrode, for the heating layers 2 of the adjacent heating areas 21 and 22, while the electrode layers 3 of the conductive areas 31 and 32 at the other two ends can be used as the other electrode, such as a negative electrode, for the heating layers 2 of the adjacent heating areas 21 and 22. In order to separate the two heating areas 21, 22 and the two conductive areas 31, 32, in this embodiment, a groove 4 is jointly provided between the two heating areas 21, 22 and between the two conductive areas 31, 32 on the atomizing surface of the liquid-conducting body 1, so that the heating layer 2 laid on the two heating areas is insulated and separated, and the electrode layer 3 laid on the two conductive areas is insulated and separated.
