Description

Atomizing heating component and atomizing heating device Technical Field

[0001] The present invention relates to the field of atomization technology, and in particular to an atomization heating component and an atomization heating device thereof. Background Art

[0002] Electric heating atomization technology is a new atomization technology that has emerged in recent years. It uses the thermal effect of a resistor to generate heat energy, which in turn heats the liquid and atomizes it into vapor. It is now widely used in medical, smart home appliances, and consumer electronics products. In addition to resistance heating, electric heating can also utilize electromagnetic heating. Magnetic induction heating utilizes components of an electronic circuit board to generate an alternating magnetic field. When a magnetically conductive metal material is placed in this alternating magnetic field, alternating currents and eddy currents are generated on the surface of the material. These eddy currents cause carriers within the material to move at high speeds and irregularly, causing collisions between the carriers and atoms. Friction generates heat energy. Resistance heating is limited by the resistance of the heating element, often restricting material selection. The heat generated by the heating element is closely related to factors such as the cross-sectional area of ​​the conductor. It often requires an external power supply, and the amount of heat generated is limited by the resistance of the product. Furthermore, it often requires the liquid-conducting material to be bonded or embedded with a porous material for operation. Once the heat is separated from the heating element, it can easily cause the core to burn. Technical issues

[0034] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0038] The terms "first," "second," etc. are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features. "Multiple" means two or more, unless otherwise expressly specified.

[0039] The above terms are only for the convenience of description and should not be understood as limiting the present technical solution.

[0040] Example 1, as shown in Figures 1 to 7, an atomizing heating component includes a porous liquid conductive liquid 100 and a porous magnetic conductive heating body 200, wherein the porous liquid conductive liquid 100 is a porous structure having micron-sized pores formed by high-temperature sintering of inorganic non-metallic aggregates and a binder. The micron-sized pores formed by high-temperature sintering of the inorganic non-metallic aggregates and the binder can provide a channel for the passage of the atomized liquid. At the same time, the porous liquid conductive liquid 100 has high strength and can provide structural support and heat insulation. The porous magnetic conductive heating body 200 is a porous magnetic conductive structure formed by directly sintering magnetic conductive material particles at high temperature or by sintering magnetic conductive material particles with a binder at high temperature. That is, there are two ways to realize the porous magnetic conductive structure: one is to directly sinter magnetic conductive material particles at high temperature, Secondly, the magnetic material particles are combined with an adhesive and sintered at high temperature to form micron-sized micropores. The porous magnetic conductive structure formed at this time can not only generate heat through electromagnetic induction, but also have a liquid-conducting function through the micron-sized micropores; the porous magnetic conductive heating body 200 is at least embedded in or attached to the surface of the porous conductive liquid 100. It can be understood that the porous magnetic conductive heating body 200 can be embedded in or attached to any surface of the porous conductive liquid 100. Multiple porous magnetic conductive heating bodies 200 can be arranged at intervals or one can be arranged continuously. Multiple porous magnetic conductive heating bodies 200 can be embedded in or attached to one surface of the porous conductive liquid 100, or multiple porous magnetic conductive heating bodies 200 can be embedded in or attached to different surfaces of the porous conductive liquid 100. As shown in FIG2 , the embedding described in the present invention can be partial embedding, that is, a portion of the porous magnetic conductive heating body 200 is buried in the porous conductive liquid 100, and a portion thereof extends beyond the surface of the porous conductive liquid 100. As shown in FIG1 , the embedding can also be full embedding, that is, the porous magnetic conductive heating body 200 is entirely disposed in the porous conductive liquid 100, that is, the surface of the porous magnetic conductive heating body 200 is flush with the porous conductive liquid 100. The porous magnetic conductive heating body 200 can be continuously or discontinuously arranged on the surface of the porous conductive liquid 100. It can be arranged on the entire surface of the porous conductive liquid 100, including being arranged on every surface of the porous conductive liquid 100. It can be arranged on a part of the surface of the porous conductive liquid 100, or it can be arranged on a part of any surface of the porous conductive liquid 100. The exposed surface of the porous magnetic conductive heating body 200 located in the atomization channel forms an atomization surface 21. It can be understood that the porous magnetic conductive heating body 200 is arranged in the atomization channel, and the exposed surface of the porous magnetic conductive heating body 200 is the atomization surface 21.The porous magnetic heating body 200 serves as a heating layer, which has a porous feature. The magnetic metal particles inside it generate heat due to the electromagnetic effect, and the porous feature ensures sufficient supply of liquid and smooth emergence of atomized steam from the micropores. Therefore, this heating layer can be made to have a heating effect on the entire surface, and the thermal efficiency of the same area is higher. The porous magnetic heating bodies 200 at other positions also have liquid conduction and heating functions. The porous magnetic heating bodies 200 at other positions can also be used as heating preheating parts to preheat and atomize the atomized liquid of the porous magnetic heating body 100 at the attached or embedded parts, thereby improving the atomization effect and enhancing the taste of the atomized steam; when the atomizing heating component is working, the porous magnetic heating body 100 guides the atomized tobacco oil to the atomizing surface 21 of the porous magnetic heating body 200, and the porous magnetic heating body 200 generates heat through the electromagnetic effect, atomizes the tobacco oil to form atomized steam, and the atomized steam forms an aerosol with the air, which is finally inhaled by the user.

[0041] In addition to the porous magnetic conductive heating body 200 being embedded or attached to the surface of the porous liquid conductive body 100, the porous magnetic conductive heating body 200 can also be buried in the porous liquid conductive body 100 to preheat the liquid, increase its flow rate, and accelerate the direction to the atomization surface 21.

[0042] It is preferred that the porous magnetic conductive heating body 200 is not provided at the contact part with the seal 50. Since the seal 50 is mostly made of rubber, plastic, etc., the porous magnetic conductive heating body 200 is not provided at the contact part between the surface of the porous conductive liquid 100 and the seal 50 to prevent the seal 50 from being deformed or burned due to the continuous heating of the porous magnetic conductive heating body 200, thereby affecting the sealing effect of the seal 50.

[0043] The thickness of the porous conductive liquid 100 is greater than that of the porous magnetic heating body 200. The porosity of the porous conductive liquid 100 is between 30% and 70%, and the micropore diameter is distributed between 5 and 100 μm. The thickness of the porous conductive liquid 100 is greater than that of the porous magnetic heating body 200 because the atomization temperature of the e-liquid is generally between 180 and 260°C. When the temperature of the porous magnetic heating body 200 reaches the atomization temperature, its temperature is relatively high, and a larger or thicker porous conductive liquid 100 heats up more slowly. The porous conductive liquid 100 is connected to the liquid storage tank of the atomization device. The material of the liquid storage tank is generally heat-resistant at around 120°C, so a thicker porous conductive liquid 100 is required as a thermal insulator.

[0044] In addition, the thickness of the porous magnetic heating body 200 provided with the atomizing surface 21 is greater than the thickness of the porous magnetic heating body 200 at other positions, so that the unit area heating temperature of the porous magnetic heating body 200 on the atomizing surface 21 is higher than the temperature on the porous magnetic heating body 200 at other positions. The porous magnetic heating body 200 on the atomizing surface 21 plays a greater role in heating and atomizing, and its unit area heating temperature needs to be higher, so it needs to be set thicker. The porous magnetic heating body 200 at other positions can play the role of preheating the atomized liquid, and the unit area heating temperature can be slightly lower, so its thickness can be smaller than the porous magnetic heating body 200 at the atomizing surface 21.

[0045] An air guide 300 is provided on the atomizing surface 21 of the porous magnetic heating body 200 for guiding air and increasing the atomizing area in the direction of the air flow. Since the porous magnetic heating body 200 is heated by electromagnetic force, unlike the traditional heating body, it has nothing to do with resistance, but is only related to the magnetic permeability and the electromagnetic switching frequency. During the heating and atomization process, the temperature of the porous magnetic heating body 200 will continue to rise as the heating time increases, and the atomization needs to maintain a relatively constant temperature. Therefore, the porous magnetic heating body 200 needs to dissipate heat quickly. Therefore, it is preferred to provide an air guide 300 on the atomizing surface 21 of the porous magnetic heating body 200. The setting of the air guide 300 can help guide air and increase the atomization area. Increasing the atomization area can increase the atomization amount. At the same time, it also makes the contact area between the heating surface and the air larger, which is beneficial to the heat dissipation of the porous magnetic heating body 200. The air quickly takes away the atomized steam, avoids the atomized steam from accumulating in the atomization chamber, and avoids the problem of burning due to high temperature.

[0046] The air guide member 300 is at least one of an air guide groove, an air guide rib, and an air guide protrusion, as shown in FIG2 , that is, the air guide member 300 can be an air guide groove, the direction of the air guide groove is in the same direction as the air flow direction, the air guide groove forms an air guide channel, a plurality of air guide grooves can be provided, and gaps are left between the air guide grooves, and the air flow along the air guide grooves can accelerate the flow rate of the air flow; as shown in FIG3 , the air guide member 300 can be an air guide rib, a plurality of air guide ribs are provided, and gaps are left between the air guide ribs to form an air guide channel, and the air flow flows along the air guide channel to accelerate the flow rate of the gas; the air guide member 300 can be an air guide protrusion, a plurality of air guide protrusions are provided, and gaps are left between the air guide protrusions to form an air guide channel, and the air flow flows along the air guide channel to accelerate the flow rate of the gas; the air guide member 300 is provided with multiple rows along the air flow direction. , gaps are left between multiple columns to form air guide channels. In the direction of air flow, the air guide pieces 300 in the same column can be arranged intermittently or continuously. Continuous arrangement is preferred for better air guide effect. In terms of arrangement, the air guide pieces 300 have multiple embodiments. The air guide pieces 300 can be arranged in parallel, that is, the air guide pieces 300 are parallel to each other. The air guide pieces 300 can be arranged radially, which means that multiple air guide pieces 300 radiate from one side of the porous magnetic heating element to the other side, and the radiation direction is still along the air flow direction, or the air guide pieces 300 are staggered, and the air guide pieces 300 are staggered, and the air guide channels formed can be along the air flow direction. The cross-sectional shape of the air guide piece 300 is polygonal, curved or a combination thereof.

[0047] The porous liquid-conducting liquid 100 has a variety of embodiments. As shown in FIG1 , the porous liquid-conducting liquid 100 is a plate-type structure. In this case, the liquid inlet surface 11 provided on the porous liquid-conducting liquid 100 is a planar structure. In conjunction with it, the porous magnetic heating body 200 is a plate-type structure embedded in the middle of the side wall of the porous liquid-conducting liquid 100, or the porous magnetic heating body 200 is a plate-type structure attached to the middle of the side wall of the porous liquid-conducting liquid 100, and the atomizing surface 21 is a planar structure. Alternatively, as shown in FIG3-6 , the porous liquid-conducting liquid 100 is a tubular structure. In this case, the liquid inlet surface 11 provided on the porous liquid-conducting liquid 100 is a curved structure. In this case, the porous magnetic heating body 200 is a tubular structure embedded or attached to the middle of the inner wall of the porous liquid-conducting liquid 100, or the porous magnetic heating body 200 is a tubular structure attached or embedded in the middle of the outer wall of the porous liquid-conducting liquid 100, and the atomizing surface 21 is a curved structure. Furthermore, as shown in FIG3-6 , As shown in Figure 2, the porous liquid-conducting liquid 100 can also be a trough structure. It can be understood that the porous liquid-conducting liquid 100 has a liquid-conducting groove 13. At this time, the liquid inlet surface 11 provided on the porous liquid-conducting liquid 100 is a groove surface structure, and the porous magnetic heating body 200 is embedded or attached to the porous liquid-conducting liquid 100 corresponding to the liquid inlet groove; or, as shown in Figure 7, the porous liquid-conducting liquid 100 can also be a bowl-shaped structure, and the porous magnetic heating body 200 is embedded or attached to the bottom of the bowl or the outer wall of the porous liquid-conducting liquid 100; the liquid inlet surface 11 provided on the porous liquid-conducting liquid 100 can be a plane, a curved surface, or even a groove surface, or other structures, which are not specifically limited here; the atomizing surface 21 can be a plane, a curved surface, an inclined surface, or a combination of the foregoing, which are not specifically limited here and can be designed according to actual needs.

[0048] As shown in Figures 1 and 2, the liquid inlet surface 11 of the porous liquid-conducting body 100 is provided with a liquid-conducting hole 12 or a liquid-conducting groove 13 to achieve a better liquid-conducting effect. For a liquid-conducting body with a porous structure, the design of the liquid-conducting groove 13 and / or the liquid-conducting hole 12 is particularly important. By setting the liquid-conducting groove 13 and / or the liquid-conducting hole 12, the surface area of ​​the liquid-conducting surface 11 of the porous liquid-conducting body 100 is increased, which is beneficial to adjusting the liquid-conducting speed and improving the liquid-conducting stability. In particular, for some porous liquid-conducting bodies 100, the liquid-conducting surface 11 is inclined, and the liquid holding time of the entire liquid-conducting surface 11 is lower than that of the flat structure and the bowl-shaped structure. The addition of the liquid-conducting groove 13 and / or the liquid-conducting hole 12 can improve the overall liquid-conducting efficiency and liquid-conducting stability.

[0049] Preparation method of atomizing heating component: take inorganic non-metallic aggregate and binder to prepare porous conductive liquid 100 slurry, take magnetic conductive material particles or magnetic conductive material particles and binder to prepare porous magnetic conductive heating body 200 slurry, and hot-die cast the porous magnetic conductive heating body 200 slurry through a mold to obtain porous magnetic conductive heating body 200. After the porous magnetic conductive heating body 200 is cooled and fixed, the porous conductive liquid 100 slurry is injected into the mold to obtain an atomizing heating component blank, and the blank is placed in a high-temperature sintering furnace and sintered at high temperature to obtain the atomizing heating component.

[0050] Commonly used materials for inorganic non-metallic aggregates include fused quartz sand, diatomaceous earth, talc, zeolite, sepiolite, medical stone, cordierite, silicon oxide, zirconium oxide and other high-temperature resistant and difficult-to-melt ceramic powders. The binder is glass powder or glaze, and the melting point of the binder is 600-1300℃.

[0051] The porous magnetic heating body 200 is made of the following raw materials: 50-100 parts of magnetic metal powder, 0-30 parts of ceramic powder, 0-40 parts of sintering aid and 0-30 parts of paraffin wax; the magnetic metal powder is at least one of pure iron, low carbon steel, iron-aluminum alloy, iron-silicon alloy, iron-nickel alloy, iron-cobalt alloy, ferrite, metal nickel and metal cobalt. These metals have good stability with the frequency change of initial magnetic permeability, strong magnetic induction and high magnetic permeability. It can be understood that the magnetic metal powder can be any one of these metal powders, or a combination of any two or more metal powders. The preparation method of the porous magnetic heating body 200 is as follows: take several parts of magnetic metal powder, several parts of ceramic powder, several parts of sintering aid and several parts of paraffin wax, mix the raw materials and sinter at high temperature, the sintering temperature is 600-1300°C, to form a porous magnetic structure. The following table shows some specific embodiments and performance test results:
