Description

Technical Field

[0001] The present application relates to the technical field of electronic cigarettes, and in particular to an electronic cigarette atomizer. Background Art

[0002] Electronic cigarettes are mainly used to quit smoking and replace cigarettes, and the atomizer is the core component of the electronic cigarette. The atomizer core is heated by electricity to quickly heat the infiltrated tobacco oil and atomize it to produce smoke for inhalation. Ceramic atomizer cores are popular because of their small pores and produce "small smoke".

[0003] Existing ceramic atomizers usually include an insulating ceramic body and a resistor connected to the ceramic body for heating. The two ends of the resistor are connected to positive and negative electrodes for electrical heating, and the heat is transferred to the ceramic body, thereby atomizing the tobacco oil that has penetrated into the ceramic body. Because the ceramic body is a non-metallic insulator, the resistor needs to be sintered and connected to the ceramic body by sticking to one side of the ceramic body, which is inconvenient to process. During the use of electronic cigarettes, improper use such as falling or impacting can easily cause the internal resistor to be damaged, affecting the heating and atomization effect. Even worse, the resistor breaks or falls off, making the entire electronic cigarette unusable, requiring the atomizer to be replaced, or the electronic cigarette is directly scrapped.

[0026] The following is combined with Figure 1-Figure 7 The present application is further described in detail. The described embodiments are only for the purpose of illustrating and explaining the invention and do not constitute the sole limitation of the invention.

[0027] The embodiment of the present application discloses an electronic cigarette atomizer seat.

[0028] Reference Figure 1 , an electronic cigarette atomizer seat includes a conductive metal-containing porous heating seat body 1, the porous heating seat body 1 is a block, and the porous heating seat body 1 can be set to one of a cylinder, a prism, a cuboid, and a ring according to the requirements of the internal structure of the electronic cigarette product. This embodiment and the following only use the cuboid-shaped porous heating seat body 1 for schematic illustration. The porous heating seat body 1 is a rectangular block formed by sintering, and the final mass composition includes aluminum, iron and silicon dioxide. Because it contains metal components, the porous heating seat body 1 can have a conductive function. Two electrodes 2 are connected to the surface of one side of the porous heating seat body 1, and the two electrodes 2 are respectively a positive electrode and a negative electrode. The electrode 2 is connected to the surface of the porous heating seat body 1 through a metal welding process. A number of tiny pores are evenly distributed inside the porous heating seat body 1. The capillary action of the pores is used to guide the liquid tobacco oil to the porous heating seat body 1 for atomization.

[0029] Reference Figure 2 In some embodiments, considering that the porous heating seat 1 needs to heat quickly, a heating element can be provided between the porous heating seat 1 and the electrode 2. The heating element is a resistor 3. The resistor 3 is a thin sheet made of nickel-chromium alloy. The shape can be a long strip, an arc, a special shape, a mesh, etc. In this embodiment, a long strip is preferred for specific description. In this embodiment, as Figure 2As shown, the resistor 3 is configured as a long thin strip. Since the porous heating seat 1 contains metal elements such as iron and aluminum, the resistor 3 is fixed to one side surface of the porous heating seat 1 through a printing process or a vacuum coating process. The process is mature, the operation is convenient, the production efficiency is improved, and the firmness is high, which avoids the resistor 3 from breaking. Furthermore, even if the resistor 3 breaks during use, the porous heating seat 1 can still generate heat normally, and will not affect the failure of the atomizer seat.

[0030] In some embodiments, the heating element may also be two unconnected resistor sheets 3, such as Figure 3 As shown, the two resistor sheets 3 are square sheets, which are arranged at a certain distance at both ends of one side surface of the porous heating seat body 1; further, as Figure 4 and Figure 5 As shown, two resistors 3 can also be respectively arranged on two opposite sides of the porous heating seat 1, and the resistors 3 can be fixed on the surface of the porous heating seat 1 by printing or vacuum coating, and the positive and negative electrodes of the electrodes 2 are respectively welded to the two resistors 3. Using two resistors 3 alone for heat conduction improves the heating efficiency of the porous heating seat 1 and ensures the atomization effect of the smoke oil. At the same time, the position of the resistors is relatively flexible, which can increase the design space for the internal structure of the electronic cigarette.

[0031] Reference Figure 1 In some embodiments, the porous heating seat body 1 is a block formed by integral sintering, and the final mass composition is composed of aluminum, iron and silicon dioxide, of which aluminum is 15-30%, iron is 55-75%, and silicon dioxide is 10-18%. In this embodiment, aluminum is preferably 22%, iron is 63%, and silicon dioxide is 15%, and the pore size of the internal pores is uniformly set to between 50-80μm, and the porosity is 40-45%. Setting the pore size of the porous heating seat body 1 to between 50-80μm can make the atomized molecules finer, and because the porous heating seat body 1 contains metallic iron and aluminum components, and the proportion is relatively large, the porous heating seat body 1 can have a conductive heating function.

[0032] Reference Figure 6In some embodiments, in order to improve the atomization effect of the porous heating seat body 1 and make the atomized molecules of the e-liquid fine, the porous heating seat body 1 can also be set as a double-layer structure in this embodiment, including a first block body 11 and a second block body 12, and the final mass components of the first block body 11 and the second block body 12 are composed of aluminum, iron and silicon dioxide. Among them, the mass composition of the first block 11 is 15-30% aluminum, 45-65% iron, and 20-35% silicon dioxide. In this embodiment, it is preferably 20% aluminum, 50% iron, and 30% silicon dioxide. The pore size of the pores of the first block 11 is uniformly set to between 40-60μm, and the porosity is 20-30%; the mass composition of the second block 12 is 8-16% aluminum, 20-40% iron, and 50-70% silicon dioxide. In this embodiment, it is preferably 14% aluminum, 34% iron, and 60% silicon dioxide. The pore size of the pores of the second block 12 is uniformly set to between 60-80μm, and the porosity is 45-55%. The first block 11 and the second block 12 are fixed by sintering to form a whole. The metal element in the first block is relatively large, that is, it has relatively good conductivity. Therefore, when there is no resistor, the positive and negative electrodes of the electrode 2 are directly set on the surface of the first block 11 away from the second block 12 by brazing; when the resistor 3 is set, the resistor 3 is connected to the surface of the first block 11 away from the second block 12 by printing or vacuum coating, and the positive and negative electrodes of the electrode 2 are set on the resistor 3 by brazing. Through the arrangement in this embodiment, the first block 11 has good conductivity, and the introduced smoke oil is driven by the capillary force of the small aperture to guide the oil into the second block 12. Since the aperture of the second block 12 is relatively large, the smoke oil can be accelerated to atomize, and the atomization performance is good and more delicate.

[0033] Reference Figure 7 In some embodiments, in order to further improve the atomization effect of the porous heating seat 1, make the smoke oil atomized molecules more delicate and have a better taste, the porous heating seat 1 can also be set as a three-layer structure in this embodiment. The only difference from the above-mentioned double-layer structure is that the porous heating seat 1 includes a first block 11, a second block 12 and a third block, the pore sizes of which gradually increase in sequence. The three-layer blocks are fixed into a whole by sintering. The final mass components of the first block 11, the second block 12 and the third block 13 are all composed of aluminum, iron and silicon dioxide. Among them, The mass composition of the first block 11 is 20-30% aluminum, 45-65% iron, and 15-25% silicon dioxide. In this embodiment, the preferred composition is 25% aluminum, 55% iron, and 20% silicon dioxide. The pore size of the pores in the first block 11 is uniformly set to be between 30-50 μm, and the porosity is 10-20%; The mass composition of the second block 12 is 15-25% aluminum, 40-50% iron, and 30-40% silicon dioxide. In this embodiment, the aluminum is preferably 20%, the iron is 45%, and the silicon dioxide is 35%. The pore size of the pores of the second block 12 is uniformly set to be between 50-70 μm, and the porosity is 25-35%. The mass composition of the third block 13 is 8-15% aluminum, 25-35% iron, and 50-70% silicon dioxide. In this embodiment, the aluminum is preferably 10%, the iron is 30%, and the silicon dioxide is 60%. The pore size of the pores of the third block 13 is uniformly set to be between 70-90 μm, and the porosity is 40-50%. Through the above arrangement, the first block 11 can maintain good conductivity, good support and good rapid heating effect due to its high metal content, small pore size and low porosity, and the smoke oil can be stably conducted to the second block through capillary action. The second block 12 serves as an intermediate layer to ensure the uniformity of heat conduction. The medium pore size balances heat diffusion and mechanical strength. The increase in porosity promotes the rapid transition of the smoke oil to the third block. The third block 13 reduces the metal proportion. The atomization efficiency is optimized after the pore size is increased. The three-layer structure design achieves efficient liquid conduction, uniform atomization and a more delicate taste.

[0034] Continue to refer to Figure 7 In some embodiments, when the porous heating seat body 1 adopts a double-layer or three-layer structure, the mechanical stress at the sintering point between the layers is weak, and it is easy to crack due to external force during transportation or use. That is, in this embodiment, the porous heating seat body 1 is also provided with a protective frame 4, and two protective frames 4 are provided, which are respectively arranged on the two end sides of the porous heating seat body 1. The protective frame 4 includes four side protection strips 42 and four corner protection sleeves 41. The four corner protection sleeves 41 are tightly arranged at the four corners of the side of the porous heating seat body 1, and the four side protection strips 42 are respectively connected to two adjacent corner protection sleeves 41. By providing the protective frame on the edges of the porous heating seat body 1, it plays a protective role.

[0035] The implementation principle of the embodiment of the present invention is that the porous heating seat body 1 is heated by an external power supply and a wire, and the positive and negative electrodes of the electrode 2 are electrically connected, so that the liquid tobacco oil is sucked into the porous heating seat body 1. Since there are a number of pores in the porous heating seat body 1, the liquid tobacco oil slowly penetrates from the part close to the electrode 2 to the surface far away from the electrode 2 through capillary action. Because the porous heating seat 1 is in a heating state, the tobacco oil is vaporized into micron-sized atomized molecules after reaching a certain temperature inside.

[0036] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
