[0022] Figure 3 is a schematic structural diagram of a heating component with double mesh sheets according to another embodiment of the present invention in an unfolded state. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Please refer to Figure 1 and Figure 2, the present utility model provides a heating component with double mesh sheets, which is used for the atomization core of an electronic cigarette and is connected to the controller of the electronic cigarette to atomize e-liquid into smoke. The heating component with double mesh sheets includes a first conductive arm 1, a second conductive arm 2, a third conductive arm 3, a first heating mesh 4 and a second heating mesh 5. The first conductive arm 1 and the second conductive arm 2 are arranged in parallel and spaced apart. The second conductive arm 2 and the third conductive arm 3 are arranged in parallel and spaced apart, and are located between the first conductive arm 1 and the third conductive arm 3. The first heating mesh 4 includes a first heating area 41, a second heating area 42 and a third heating area 43. The first end of the first heating area 41 is connected to the first conductive arm 1, the second end of the first heating area 41 is connected to the second heating area 42, and the mesh holes of the first heating area 41 are diamond-shaped.

[0025] The first end of the third heating area 43 is connected to the second heating area 42, the second end of the third heating area 43 is connected to the second conductive arm 2, and the mesh holes of the third heating area 43 are diamond-shaped. The second heating area 42 is located between the first heating area 41 and the third heating area 43. The area of the mesh holes of the second heating area 42 is smaller than the area of the mesh holes of the first heating area 41 and the area of the mesh holes of the third heating area 43. The resistance value of the second heating area 42 is smaller than the resistance value of the first heating area 41 and the resistance value of the third heating area 43.

[0026] Therefore, when the first heating mesh 4 is powered on, the heat generated by the second heating area 42 is less than the heat generated by the first heating area 41 and the third heating area 43. However, since the second heating area 42 is located between the first heating area 41 and the third heating area 43, it receives the heat radiated from the first heating area 41 and the third heating area 43. Therefore, by setting the resistance value of the second heating area 42 to be smaller than the resistance value of the first heating area 41 and the resistance value of the third heating area 43, the heat distribution of the three areas is made uniform.

[0027] Among them, the second heating area 42 includes a first heating arm a, a second heating arm b and a third heating arm c. The first end of the first heating arm a is connected to the first heating area 41, and the second end of the first heating arm a is connected to the third heating area 43. The first end of the second heating arm b is connected to the first end of the first heating arm a, the second end of the second heating arm b is connected to the first end of the third heating arm c, and the second end of the third heating arm c is connected to the second end of the first heating arm a. The first heating arm a, the second heating arm b and the third heating arm c form a triangle with mesh holes. Therefore, not only is the structure relatively stable and not easily deformed during vibration, but also the heat distribution is relatively uniform.

[0028] The second heating area 42 further includes a first heat-conducting arm d, one end of which is connected to the second end of the second heating arm b and the first end of the third heating arm c, so that heat can be diffused to more areas. The first heating arm a, the second heating arm b and the third heating arm c form a first equilateral triangle, and the first heat-conducting arm d is located on the perpendicular bisector of the first equilateral triangle, so that not only the uniformity of heat is improved, but also the stability of the structure is improved.

[0029] The second heating zone 42 also includes a first connecting arm e, a second connecting arm f and a fourth heating arm g. The first connecting arm e and the second connecting arm f are arranged in parallel and spaced apart. The first end of the first connecting arm e is connected to the first end of the first heating arm a, and the second end of the first connecting arm e is connected to the first end of the fourth heating arm g. The first end of the second connecting arm f is connected to the second end of the first heating arm a, and the second end of the second connecting arm f is connected to the second end of the fourth heating arm g. The first end of the fourth heating arm g is connected to the first heating zone 41, and the second end of the fourth heating arm g is connected to the third heating zone 43. The fourth heating arm g is spaced apart from the first heating arm a. This structure can further improve the uniformity of heat distribution. Preferably, the first connecting arm e, the second connecting arm f, the first heating arm a and the fourth heating arm g form a square, that is, the mesh formed by the first connecting arm e, the second connecting arm f, the first heating arm a and the fourth heating arm g is square.

[0030] The second heating area 42 further includes a fifth heating arm h and a sixth heating arm j, which are located on the side of the fourth heating arm g facing away from the first heating arm a. The first end of the fifth heating arm h is connected to the first end of the fourth heating arm g, the second end of the fifth heating arm h is connected to the first end of the sixth heating arm j, and the second end of the sixth heating arm j is connected to the second end of the fourth heating arm g.

[0031] The second heating area 42 further includes a second heat-conducting arm k, one end of which is connected to the second end of the fifth heating arm h and the first end of the sixth heating arm j, and the fifth heating arm h and the sixth heating arm j are located between the fourth heating arm g and the second heat-conducting arm k. The fourth heating arm g, the fifth heating arm h and the sixth heating arm j form a second equilateral triangle, and the second heat-conducting arm k is located on the perpendicular bisector of the second equilateral triangle, thereby not only improving the uniformity of heat but also improving the stability of the structure.

[0032] The area of the mesh formed by the first connecting arm e, the second connecting arm f, the first heating arm a, and the fourth heating arm g is the first area, and the area of the mesh formed by the fourth heating arm g, the fifth heating arm h, and the sixth heating arm j is the second area. The first area is greater than the second area. The meshes in the middle region of the second heating zone 42 are larger than the meshes in the remaining regions within the second heating zone 42. Therefore, heat accumulation in the middle is better avoided, and the uniformity of heat distribution is improved. Preferably, the area of the second heating zone 42 is equal to half of the area of the first heating zone 41. Similarly, the area of the second heating zone 42 is equal to half of the area of the third heating zone 43. The resistance value of the second heating zone 42 is less than half of the resistance value of the first heating zone 41. Similarly, the resistance value of the second heating zone 42 is less than half of the resistance value of the third heating zone 43.

[0033] The first end of the second heating mesh 5 is connected to the second conductive arm 2, and the second end of the second heating mesh 5 is connected to the third conductive arm 3. In this embodiment, the second heating mesh 5 and the first heating mesh 4 are at the same height position. The second heating mesh 5 has the same structure as the first heating mesh 4, and the structure thereof will not be described in detail here. Since the structures of the two are the same, they also have the same technical effects.

[0034] 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 that are likely to occur through welding.

[0035] Please refer to Figure 3 , in another embodiment, the structure of this embodiment is similar to that of the above embodiment. The similarities are as follows: Both this embodiment and the above embodiment include the first conductive arm 1, the second conductive arm 2, the third conductive arm 3, the first heating mesh 4, and the second heating mesh 5. The first end of the first heating mesh 4 is connected to the first conductive arm 1, the second end of the first heating mesh 4 is connected to the second conductive arm 2, the first end of the second heating mesh 5 is connected to the second conductive arm 2, and the second end of the second heating mesh 5 is connected to the third conductive arm 3. The differences are as follows: In this embodiment, the meshes in the second heating zone 42 of the first heating and the second heating mesh 5 are circular. This structure is more stable, and the heat generation in the second heating zone 42 is smaller.

[0036] The present utility model also discloses an atomization core applied to an electronic cigarette. The atomization core includes a porous oil guiding member and a heating component with a double mesh sheet. The heating component with a double mesh sheet is attached to the porous oil guiding member, wherein the heating component with a double mesh sheet is the above-mentioned heating component with a double mesh sheet. Since the heating component with a double mesh sheet in this embodiment has the same structure as the atomization core of the above-mentioned heating component with a double mesh sheet, it also has the same technical effects. The porous oil guiding member can be made of materials such as cotton or ceramics.

[0037] 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) or a negative temperature coefficient thermistor (NTC). 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 dry burning. Compared with other temperature sensors, this structure has the advantages of accurate detection and efficient control.

[0038] In summary, since the second heating area 42 of the present utility model is located between the first heating area 41 and the third heating area 43, the area of the mesh holes in the second heating area 42 is smaller than the area of the mesh holes in the first heating area 41 and the area of the mesh holes in the third heating area 43, and the resistance value of the second heating area 42 is smaller than the resistance value of the first heating area 41 and the resistance value of the third heating area 43. Therefore, during operation, the heat of the first heating area 41, the second heating area 42, and the third heating area 43 is relatively uniform, avoiding the problem that the heat is concentrated in the middle area where the second heating area 42 is located, so that the middle area where the second heating area 42 is located is prone to carbon accumulation, and avoiding the generation of burnt smell.
