[0002] Currently, there are electronic atomizer products on the market that use double-hole heating wires. The structure of the double-hole heating wire is generally two small circles inside a large circle.

More oil enters the thin-walled position, while less oil enters the thick-walled position. As a result, when the heating wire is working, the atomization volume is not full enough, resulting in a poor user experience. Utility Model Content

[0028] See also Figure 1 to Figure 2 As shown, the utility model discloses a specific embodiment of a two-hole heating wire structure, including: a ceramic column 10, wherein the ceramic column 10 is provided with two through holes 11, and the inner wall of the through hole 11 is connected and fixed with a heating wire 20, and the heating wire 20 is connected with a first pin 30 and a second pin 40; the two through holes 11 are distributed on both sides of the ceramic column 10, and the through holes 11 are elliptical holes.

[0029] Specifically, two through holes 11 are opened through the ceramic column 10, and the inner wall of the through hole 11 is connected and fixed with a heating wire 20. The two through holes 11 are distributed on both sides of the ceramic column 10, and the through holes 11 are elliptical holes to ensure that the wall thickness of the product is uniform and the oil intake is consistent, which can provide more heating area, which means that more tobacco oil can contact the heating wire 20 and be atomized to enhance the fullness of atomization; in addition, since the heating wire 20 is connected to the inner wall of the through hole 11, when current passes through the heating wire 20, the heat will be evenly transferred to the ceramic column 10 to achieve a more uniform heating effect, reduce the situation where the tobacco oil is overheated or not fully heated, and improve the restoration degree and taste of the smoke, thereby providing a better user experience.

[0030] In addition, the setting of two through holes 11 increases the smoothness of airflow. In addition, the two heating wires 20 can work at the same time, or they can work alternately according to user requirements. The two heating wires 20 working at the same time can reduce the heating power, and will not damage the reduction degree of the oil product, so as to enhance the user's taste; in addition, the setting of the two heating wires 20 also increases the life of the heating wire 20, so that a larger capacity product can be made, and the use cost can be reduced; in addition, the structural design of the two heating wires 20 makes the heating wire 20 more complete when atomized, and the smoke reduction degree is better, and no condensed water will be generated to affect the user's use experience.

[0031] In one embodiment, the ceramic column 10 is a cylinder, and the two through holes 11 are symmetrically arranged about the center line of the cylinder.

[0032] Specifically, the two through holes 11 are symmetrically arranged about the center line of the ceramic column 10, so that the heating wire 20 can heat the entire e-liquid more evenly, avoiding uneven heating or local overheating. In addition, the through hole 11 is designed with an elliptical hole, which can improve the heating stability, because the elliptical hole can better disperse the heat, reduce the situation of partial overheating or insufficient heating of the e-liquid, thereby improving the restoration degree and taste of the smoke. In addition, the two evenly distributed elliptical holes can provide a larger heating surface area, thereby improving the heating effect, which means that more e-liquid can contact the heating wire 20 and be atomized, producing more and more uniform smoke. In addition, since the through holes 11 are evenly distributed and the elliptical hole design is adopted, the wear and aging of the heating wire 20 can be reduced, which can increase the service life of the heating core and reduce the number of times the heating core is replaced.

[0033] In other embodiments, the through hole 11 may also be in other shapes.

[0034] In one embodiment, the outer diameter of the cylinder is 5-7 mm.

[0035] Specifically, a ceramic column 10 with a certain diameter can provide good structural stability, ensuring that the heating core is not easily deformed or damaged during use, which helps to maintain the long-term stability and reliability of the heating core. In addition, a ceramic column 10 with a larger diameter can provide a larger surface area, which is conducive to dissipating heat and avoiding local overheating, thereby protecting other components from damage. In addition, the ceramic material has good insulation properties, and a ceramic column 10 with an outer diameter of 5-7 mm can effectively isolate the heating component and prevent heat from being transferred to other components.

[0036] In other embodiments, the ceramic column 10 may also be a square column or other column shapes.

[0037] In one embodiment, the height of the cylinder is 5-8 mm.

[0038] Specifically, the height of the cylinder can control the distance between the heating wire 20 and the e-liquid, thereby controlling the heating temperature; if the cylinder is too high, the heating wire 20 may be too far away from the e-liquid, resulting in uneven heating, which will affect the quality and taste of the smoke. In addition, a suitable cylinder height can improve the heating efficiency, thereby producing more and more uniform smoke. This is because the height of the cylinder and the diameter of the circular hole jointly control the contact area between the e-liquid and the heating wire 20. By optimizing the height of the cylinder, the heating surface area and the uniform heating effect can be enhanced. In addition, a proper cylinder height can reduce the overflow of the e-liquid; if the cylinder is too short, the e-liquid may not be fully absorbed, thereby overflowing, affecting the user experience.

[0039] In a specific embodiment, the major axis of the elliptical hole is 1.4-2 mm, and the minor axis is 0.8-1.2 mm.

[0040] Specifically, the aperture size of the elliptical hole can control the heating temperature of the heating core. The long axis of the elliptical hole is 1.4-2mm, and the short axis is 0.8-1.2mm, which can control the heating temperature of the heating wire 20 to avoid partial overheating or insufficient heating of the smoke oil. In addition, the long axis of the elliptical hole is 1.4-2mm, and the short axis is 0.8-1.2mm, which can improve the heating efficiency of the heating core, thereby producing more and more uniform smoke, because the elliptical hole can make more smoke oil contact with the heating wire 20 and be atomized, thereby enhancing the heating surface area and uniform heating effect. In addition, smaller elliptical holes can also reduce the overflow of smoke oil, because the smaller the aperture of the elliptical hole, the slower the speed of smoke generation will be, and the quality and taste of the smoke will be better.

[0041] In one embodiment, the heating wire 20 is spiral-shaped, one end of the heating wire 20 is fixedly connected to the first pin 30 , and the other end of the heating wire 20 is fixedly connected to the second pin 40 . The first pin 30 and the second pin 40 are embedded in the ceramic column 10 .

[0042] Specifically, a spiral heating wire 20 is used, and its ends are connected to the first pin 30 and the second pin 40, and embedded in the ceramic column 10. It can provide advantages such as stable connection, uniform heating, effective use of space, and high temperature resistance of ceramic materials, thereby improving the performance and reliability of the electronic atomizer.

[0043] In one embodiment, the heating wire 20 is in a mesh core shape, one end of the heating wire 20 is fixedly connected to the first pin 30 , and the other end is fixedly connected to the second pin 40 . The first pin 30 and the second pin 40 are embedded in the inner wall of the through hole 11 .

[0044] Specifically, by connecting the two ends of the heating wire 20 to the first pin 30 and the second pin 40 respectively, it can be ensured that the heating wire 20 is firmly connected to other components of the electronic atomizer, and the heating wire 20 is prevented from falling off or breaking due to vibration or movement. In addition, the mesh-shaped heating wire 20 can provide a larger heating surface area, thereby achieving a more uniform heating effect, which is conducive to the full volatilization of the smoke oil and the generation of uniform smoke. In addition, the first pin 30 and the second pin 40 are embedded in the inner wall of the through hole 11, which can effectively utilize the space, ensure the compact structure of the entire heating core, and prevent the heating wire 20 from contacting other metal parts to cause short circuits or other safety hazards.

[0045] In one embodiment, the heating wire 20 is made of iron-chromium-aluminum alloy or nickel-chromium alloy.

[0046] Specifically, both the iron-chromium-aluminum alloy and the nickel-chromium alloy have good high temperature resistance and can work stably at higher temperatures. The use of the heating wire 20 made of these materials in the electronic atomizer can ensure that it is not easy to deform or oxidize when heated, thereby extending the service life of the heating wire 20. In addition, both the iron-chromium-aluminum alloy and the nickel-chromium alloy have good corrosion resistance and can maintain stable performance in an environment in contact with the smoke oil, and will not affect the heating effect and safety performance due to corrosion. In addition, both the iron-chromium-aluminum alloy and the nickel-chromium alloy have low resistivity. The use of the heating wire 20 made of these materials can achieve a more uniform heating effect, which is conducive to the full volatilization of the smoke oil and the generation of uniform smoke.

[0047] In one embodiment, the first pin 30 , the second pin 40 and the heating wire 20 are integrally formed.

[0048] Specifically, since the pin and the heating wire 20 are integrally formed, the connection between them is more firm and stable, which can reduce the possibility of circuit failure or performance degradation caused by loose connection or poor contact. In addition, the integrally formed structure can reduce resistance loss and improve power conversion efficiency, which helps to reduce energy consumption and improve the performance of the device.

[0049] In one embodiment, the heating wire 20 and the ceramic column 10 are an integrally formed structure.

[0050] Specifically, the heating wire 20 and the ceramic column 10 are integrally formed by a die-casting process. Through the integrally formed design, the heating wire 20 and the ceramic column 10 form a close connection, avoiding the problem of loosening or falling off that may occur in the traditional assembly method. This can ensure that the heating wire 20 will not lose stability due to loosening during use, thereby improving the reliability of the electronic atomizer. In addition, the ceramic material has good thermal conductivity. After being integrally formed with the heating wire 20, it can effectively improve the heat conduction efficiency, so that the heating wire 20 can dissipate heat more quickly when heated, reduce the operating temperature of the heating wire 20, and extend its service life. In addition, since the heating wire 20 and the ceramic column 10 are integrally formed, the ceramic material can serve as an insulating layer to effectively isolate the heating area from other components. In this way, the influence of heat on other components can be reduced during use, thereby improving the safety of the electronic atomizer. In addition, the use of an integrally formed structure can simplify the production process and reduce manufacturing costs. At the same time, the integrally formed design is also more convenient during maintenance and replacement, reducing the difficulty of operation that may occur during maintenance.

[0051] The utility model also discloses an electronic atomizer, comprising the two-hole heating wire structure as described above.

[0052] Specifically, two through holes 11 are opened through the ceramic column 10, and the inner wall of the through hole 11 is connected and fixed with a heating wire 20. The two through holes 11 are distributed on both sides of the ceramic column 10, and the through holes 11 are elliptical holes to ensure that the wall thickness of the product is uniform and the oil intake is consistent, which can provide more heating area, which means that more tobacco oil can contact the heating wire 20 and be atomized to enhance the fullness of atomization; in addition, since the heating wire 20 is connected to the inner wall of the through hole 11, when current passes through the heating wire 20, heat will be evenly transferred to the ceramic column 10 to achieve a more uniform heating effect, reduce the situation where the tobacco oil is partially overheated or not fully heated, and improve the restoration degree and taste of the smoke, so that the electronic atomizer can provide a better user experience.

[0053] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
