[0020] The present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Please refer to Figure 1 and Figure 2 , the present utility model provides a double-mesh heating component for an electronic cigarette atomizing core, which is connected to a controller of an electronic cigarette to atomize e-liquid to form smoke. The double-mesh heating component includes a first conductive arm 1, a second conductive arm 2, a third conductive arm 3, a first heating mesh 4, a second heating mesh 5, a first pin 6, a second pin 7 and a third pin 8. The first conductive arm 1 and the second conductive arm 2 are arranged at intervals and are parallel to each other. The second conductive arm 2 and the third conductive arm 3 are arranged at intervals and are parallel to each other.

[0022] The first conductive arm 1 is provided with a first connecting protrusion 11 and a second connecting protrusion 12 which are spaced apart, and the first connecting protrusion 11 and the second connecting protrusion 12 are located on the same side of the first conductive arm 1. The second conductive arm 2 is provided with a third connecting protrusion 21, a fourth connecting protrusion 22, a fifth connecting protrusion 23 and a sixth connecting protrusion 24 which are spaced apart. The third connecting protrusion 21 and the fourth connecting protrusion 22 are located on the first side of the second conductive arm 2, and the fifth connecting protrusion 23 and the sixth connecting protrusion 24 are located on the second side of the second conductive arm 2. The first side and the second side of the second conductive arm 2 are arranged in opposite positions.

[0023] The first end of the first heating mesh 4 is connected to the first connecting protrusion 11 and the second connecting protrusion 12, and the second end of the first heating mesh 4 is connected to the third connecting protrusion 21 and the fourth connecting protrusion 22. The third conductive arm 3 is provided with a seventh connecting protrusion 31 and an eighth connecting protrusion 32 which are spaced apart, and both the seventh connecting protrusion 31 and the eighth connecting protrusion 32 are located on the same side of the third conductive arm 3.

[0024] The first end of the second heating mesh 5 is connected to the fifth connecting protrusion 23 and the sixth connecting protrusion 24, and the second end of the second heating mesh 5 is connected to the seventh connecting protrusion 31 and the eighth connecting protrusion 32. Both the first heating mesh 4 and the second heating mesh 5 are arc-shaped. The first heating mesh 4 and the second heating mesh 5 and the first conductive arm 1, the second conductive arm 2 and the third conductive arm 3 are of an integrally formed structure and are in an open ring shape, thus avoiding problems such as uneven heat distribution and easy detachment caused by welding. It can be understood that the mesh shape of the first heating mesh 4 and the second heating mesh 5 is not specifically limited here.

[0025] Among them, the first connecting protrusion 11 to the eighth connecting protrusion 32 are all substantially isosceles triangles, so that it is not easy to fall off when the heating mesh vibrates up and down. The first connecting protrusion 11, the third connecting protrusion 21, the fifth connecting protrusion 23 and the seventh connecting protrusion 31 are located at the same radial position of the double-mesh heating component, and the second connecting protrusion 12, the fourth connecting protrusion 22, the sixth connecting protrusion 24 and the eighth connecting protrusion 32 are located at the same radial position of the double-mesh heating component. Therefore, the first heating mesh 4 and the second heating mesh 5 are relatively evenly stressed, improving the reliability, and the heat is also evenly distributed, and the atomization effect is good.

[0026] The first pin 6 is welded to the first conductive arm 1, the second pin 7 is welded to the second conductive arm 2, and the third pin 8 is welded to the third conductive arm 3. The cross-sectional area of the first pin 6 is larger than that of the first conductive arm 1, and the cross-sectional area of the third pin 8 is larger than that of the third conductive arm 3. The cross-sectional area of the second pin 7 is larger than that of the second conductive arm 2. Therefore, not only the reliability of the structure is enhanced, but also the resistance is small, avoiding overheating and softening, so that the heating mesh is not easily deformed due to external forces. It can be understood that when assembled into an electronic cigarette, the first pin 6 to the third pin 8 are all connected to the controller of the electronic cigarette.

[0027] In addition, the first conductive arm 1 is provided with a first welding groove 13 and a second welding groove 14. The first welding groove 13 and the second welding groove 14 are arranged at intervals. The first welding groove 13 and the first connecting protrusion 11 are located at the same height position of the first conductive arm 1. The second welding groove 14 and the second connecting protrusion 12 are located at the same height position of the first conductive arm 1. The groove walls of the first welding groove 13 and the second welding groove 14 are both welded to the first pin 6. Therefore, even when the areas where the first connecting protrusion 11 and the second connecting protrusion 12 are located are stressed during production, it is not easily deformed, and the problem of resistance change caused by deformation is preferably avoided.

[0028] The first conductive arm 1 is further provided with a third welding groove 15 and a fourth welding groove 16. The third welding groove 15 and the fourth welding groove 16 are arranged at intervals. The first welding groove 13 and the second welding groove 14 are located between the third welding groove 15 and the fourth welding groove 16. The groove walls of the third welding groove 15 and the fourth welding groove 16 are both welded to the first pin 6. Therefore, the connection stability can be improved. Preferably, the distance between the first welding groove 13 and the third welding groove 15 is equal to the distance between the second welding groove 14 and the fourth welding groove 16. By providing the first welding groove 13 to the third welding groove 15, accurate alignment can be achieved during welding, the consistency of the product is improved, and the product qualification rate is high. In this embodiment, the structures of the first conductive arm 1 to the third conductive arm 3 are the same.

[0029] Please refer to Figure 3 , in another embodiment of the present invention, the structure of this embodiment is similar to that of the above embodiment. The main difference is that: the first pin 6 includes a connecting column portion 61, the connecting column portion 61 is welded to the first conductive arm 1, and one end of the connecting column portion 61 is bent and extended to form a guiding portion 62. One end of the first conductive arm 1 is located between the guiding portion 62 and the connecting column portion. By providing the guiding portion 62, when the double-network heating component and the porous oil guiding pipe are assembled to form an electronic cigarette atomization core, the double-network heating component and the porous oil guiding pipe are well aligned, and the problem of the porous oil guiding pipe being skewed is preferably avoided. In this embodiment, the structures of the first pin 6, the second pin 7, and the third pin 8 are the same.

[0030] The present utility model also discloses an electronic cigarette atomizing core, which includes a porous oil guiding tube and a double-network heating component. At least part of the double-network heating component is attached inside the porous oil guiding tube. Among them, the double-network heating component is the double-network heating component of any one of the above first aspects. Since the double-network heating component of this embodiment has the same atomizing core structure as the above double-network heating component, it also has the same technical effects.

[0031] In addition, the first heating mesh 4 forms a first temperature sensing unit for detecting its own heating temperature. The second heating mesh 5 forms a second temperature sensor unit for detecting its own heating temperature. The first heating mesh 4 and the second heating mesh 5 can be made of thermistor materials such as copper-zinc alloy and nickel-manganese alloy. It can be a positive temperature coefficient thermistor (PTC, Positive Temperature Coefficient thermistor) or a negative temperature coefficient thermistor (NTC, Negative Temperature Coefficient thermistor). The resistance value of the PTC thermistor increases with the increase of temperature, while the resistance value of the NTC thermistor decreases with the increase of temperature. During operation, the controller of the electronic cigarette controls the current of the first heating mesh 4 and the second heating mesh 5 according to the resistance value during the heating process of the first heating mesh 4 and the resistance value during the heating process of the second heating mesh 5, thus better avoiding the problem of dry burning that is likely to occur when the user smokes at an angle. Compared with other temperature sensors, this structure has the advantages of accurate detection and efficient control.

[0032] In summary, since the first end of the first heating mesh 4 of the present utility model is connected to the first connecting protrusion 11 and the second connecting protrusion 12, the second end of the first heating mesh 4 is connected to the third connecting protrusion 21 and the fourth connecting protrusion 22, the first end of the second heating mesh 5 is connected to the fifth connecting protrusion 23 and the sixth connecting protrusion 24, the second end of the second heating mesh 5 is connected to the seventh connecting protrusion 31 and the eighth connecting protrusion 32, and the first heating mesh 4 and the second heating mesh 5 and the first conductive arm 1, the second conductive arm 2 and the third conductive arm 3 are integrally formed structures. Therefore, through the auxiliary connection function of the connecting protrusions, the stability of the connection between the conductive arm and the heating mesh can be improved. Moreover, since the connecting protrusions are arranged at intervals, it is beneficial to the discharge of smoke, avoiding the concentration of heat in one area, resulting in the problem of dry burning. In addition, this structure can improve the toughness of the connection between the heating mesh and the conductive arm, so that it is not easy to break during vibration.
