Description

Technical Field

[0001] The present invention relates to the technical field of electronic cigarettes, and in particular to a heating structure and an electronic cigarette device. Background Art

[0002] Electronic cigarettes are also known as virtual cigarettes, steam cigarettes, aerosol generating devices, etc. They are mainly used to simulate the feeling of smoking without affecting health, so as to help people quit smoking or replace cigarettes. Among them, some electronic cigarettes use mesh heating wires as heating components, which are set on oil-conducting cotton or porous ceramic bodies or air heating tubes. The mesh heating wires are heated by electricity to heat the tobacco oil (or tobacco paste) and atomize it to produce smoke.

[0003] like Figure 1 As shown, the existing mesh heating wire generally includes a first electrode portion 81 and a second electrode portion 82 arranged opposite to each other and a mesh heating portion 83 connected between the first electrode portion 81 and the second electrode portion 82. The mesh heating portion 83 includes a plurality of heating wires 831 arranged in sequence (four are shown in the figure), and each heating wire 831 is bent and extended in a wave shape (specifically, bent and extended in a zigzag shape). The waveforms of the two adjacent heating wires 831 are opposite (that is, the two adjacent heating wires 831 are symmetrically arranged up and down) and are connected to each other, thereby forming a mesh structure.

[0004] However, the mesh heating wire of the above structure has a low space utilization rate (i.e., the effective area of ​​the heating wire accounts for a low proportion within the unit area of ​​space, that is, the gap area between the heating wires 831 in the mesh heating wire accounts for a large proportion), and has a low heating efficiency, a weak heating explosive force, and a relatively small contact area with the e-liquid, thereby affecting the atomization efficiency and taste; if the heat production is to be increased, the size of the mesh heating wire needs to be increased, which will increase the space it occupies and increase the production cost. Summary of the invention

[0005] The object of the present invention is to provide a heating structure which can improve space utilization and heating efficiency, thereby improving atomization efficiency, saving space and reducing production costs.

[0011] In one achievable manner, the spacing between the first electrical connection parts of the corresponding heating units in two adjacent heating wires is 0.05mm-0.1mm, and the spacing between the second electrical connection parts of the corresponding heating units in two adjacent heating wires is 0.05mm-0.1mm.

[0012] In one achievable manner, the width of the first electrical connection portion and the width of the second electrical connection portion are both 0.05 mm-0.1 mm.

[0030] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0031] The terms "first", "second", "third", "fourth" and the like (if any) in the description and claims of the present invention are used to distinguish similar objects and are not necessarily used to describe a particular sequence or order.

[0032] The directional words such as up, down, left, right, front, back, top, bottom, etc. (if any) involved in the specification and claims of the present invention are defined by the positions of the structures in the drawings and the positions of the structures relative to each other, and are only for the clarity and convenience of expressing the technical solution. It should be understood that the use of directional words should not limit the scope of protection claimed in the present invention.

[0033] like Figures 2 to 4As shown, the heating structure provided by the embodiment of the present invention includes a first electrode portion 21 and a second electrode portion 22 arranged opposite to each other at intervals, and a mesh heating portion 1 connected between the first electrode portion 21 and the second electrode portion 22. The mesh heating portion 1 includes at least one heating wire group 100, each heating wire group 100 includes at least two heating wires 11, and at least two heating wires 11 in each heating wire group 100 are arranged at intervals along the first direction Y, each heating wire 11 is bent and extended in a wave shape, and both ends of each heating wire 11 are connected to the first electrode portion 21 and the second electrode portion 22 respectively.

[0034] Along the first direction Y, the crest positions M of the heating wires 11 in each heating wire group 100 correspond one to one, and the trough positions N of the heating wires 11 in each heating wire group 100 correspond one to one.

[0035] Along the first direction Y, the two opposite sides of the heating wire 11 are respectively the first side and the second side, and each heating wire 11 is formed with an empty groove 116 on the first side at the wave crest position M and the second side at the wave trough position N (for example, along the first direction Y, the two opposite sides of the heating wire 11 are respectively the upper side and the lower side, and the heating wire 11 is formed with an empty groove 116 on the lower side at the wave crest position M and the upper side at the wave trough position N). In this embodiment, the empty groove 116 is a V-shaped groove or an inverted V-shaped groove.

[0036] Every two adjacent heating wires 11 in the heating wire group 100 are respectively a first heating wire 11A and a second heating wire 11B, the second heating wire 11B is located above the first heating wire 11A, each crest position M of the first heating wire 11A is located in the corresponding empty groove 116 on the second heating wire 11B (that is, each crest position M of the first heating wire 11A is located in the empty groove 116 corresponding to the crest position M of the second heating wire 11B), and each trough position N of the second heating wire 11B is located in the corresponding empty groove 116 on the first heating wire 11A (that is, each trough position N of the second heating wire 11B is located in the empty groove 116 corresponding to the trough position N of the first heating wire 11A), so that the first heating wire 11A and the second heating wire 11B form a mutually plug-in and interlocking structure.

[0037] Specifically, the heating structure provided in this embodiment is configured to redesign the shape and arrangement of the mesh heating portion 1, so that the peak positions M of the heating wires 11 in the heating wire group 100 are set in one-to-one correspondence, and the trough positions N of the heating wires 11 in the heating wire group 100 are set in one-to-one correspondence, that is, the waveform structures of the heating wires 11 in the heating wire group 100 are the same; and in the heating wire group 100, each peak position M of the first heating wire 11A is located in the corresponding empty groove 116 on the second heating wire 11B, and each trough position N of the second heating wire 11B is located in the first heating wire 11A. In the corresponding empty groove 116 on 11A, that is, the two adjacent heating wires 11 are of a structure that is plugged into each other, thereby improving the space utilization rate of the mesh heating part 1; under the conditions of the same size and the same resistivity as the existing mesh heating wire (that is, the length, width and thickness of the mesh heating part 1 are the same, and the resistivity of the heating wire 11 is the same), the mesh heating part 1 of the heating structure has a larger effective area, a higher heating efficiency, and a larger contact area with the smoke oil, so the atomization efficiency is higher, and the taste of the smoke oil can be fully atomized and restored, and it is beneficial to save space and reduce production costs.

[0038] like Figure 3 and Figure 4 As shown, as an embodiment, each heating wire 11 includes a plurality of heating units 110 connected in sequence, each heating unit 110 includes a first electrical connection portion 111 and a second electrical connection portion 112 arranged opposite to each other, the first electrical connection portion 111 and the second electrical connection portion 112 are connected to form a V-shaped or inverted V-shaped structure, the connection position of the first electrical connection portion 111 and the second electrical connection portion 112 is located at the peak position M or the trough position N of the heating wire 11, and an empty groove 116 is formed between adjacent first electrical connection portions 111 and second electrical connection portions 112 (the empty groove 116 is formed between the first electrical connection portion 111 and the second electrical connection portion 112 in each heating unit 110 and between the adjacent first electrical connection portions 111 and the second electrical connection portions 112 in each two adjacent heating units 110).

[0039] like Figure 3 and Figure 4 As shown, as an implementation mode, each heating wire 11 bends and extends in a wave shape along the second direction X, and each heating wire 11 includes a plurality of heating units 110 sequentially connected along the second direction X; wherein the second direction X is perpendicular to the first direction Y. In this embodiment, each heating wire 11 bends and extends in a wave shape in the transverse direction, and at least two heating wires 11 in each heating wire group 100 are arranged at intervals in the longitudinal direction.

[0040] like Figure 3 and Figure 4As shown, as an embodiment, the first electrical connection portion 111 and the second electrical connection portion 112 are both straight strip structures, and along the second direction X, the first electrical connection portion 111 and the second electrical connection portion 112 in each heating unit 110 are symmetrically arranged (i.e., symmetrically arranged on the left and right), so that the heating wire 11 has a sawtooth-shaped wavy structure as a whole. Of course, in other embodiments, the first electrical connection portion 111 and the second electrical connection portion 112 can also be an arc-shaped curved structure (in this case, the heating wire 11 has an arc-shaped wavy structure as a whole), etc.

[0041] like Figure 3 and Figure 4 As shown, as an embodiment, in each heating wire group 100, the first electrical connection parts 111 of the corresponding heating units 110 of two adjacent heating wires 11 are arranged in parallel and spaced apart, and the second electrical connection parts 112 of the corresponding heating units 110 of two adjacent heating wires 11 are arranged in parallel and spaced apart.

[0042] like Figure 4 As shown, as an embodiment, the spacing a1 between the first electrical connection parts 111 of the corresponding heating units 110 in two adjacent heating wires 11 is 0.05mm-0.1mm, and the spacing a2 between the second electrical connection parts 112 of the corresponding heating units 110 in two adjacent heating wires 11 is 0.05mm-0.1mm.

[0043] like Figure 4 As shown, as an implementation mode, the spacing a1 between the first electrical connection parts 111 of the corresponding heating units 110 of two adjacent heating wires 11 is equal to the spacing a2 between the second electrical connection parts 112 , both of which are 0.05 mm.

[0044] like Figure 4 As shown, as an implementation mode, the width b1 of the first electrical connection portion 111 and the width b2 of the second electrical connection portion 112 are equal, and the width b1 of the first electrical connection portion 111 and the width b2 of the second electrical connection portion 112 are both 0.05 mm-0.1 mm.

[0045] like Figure 4 As shown, as an implementation manner, the width b1 of the first electrical connection portion 111 and the width b2 of the second electrical connection portion 112 are both 0.07 mm.

[0046] like Figures 2 to 4As shown, as an embodiment, the mesh heating part 1 includes at least two heating wire groups 100, at least two heating wire groups 100 are arranged in sequence along the first direction Y (i.e., arranged in sequence up and down), and each adjacent two heating wire groups 100 are respectively a first heating wire group and a second heating wire group; along the first direction Y, the peak position M of the heating wire 11 in the first heating wire group corresponds to the trough position N of the heating wire 11 in the second heating wire group, and the trough position N of the heating wire 11 in the first heating wire group corresponds to the peak position M of the heating wire 11 in the second heating wire group (i.e., the waveform structure of the heating wire 11 in the first heating wire group is exactly opposite to the waveform structure of the heating wire 11 in the second heating wire group). By setting the heating wire 11 in the first heating wire group and the heating wire 11 in the second heating wire group to have opposite waveform structures, the heat generated by the entire mesh heating part 1 is more evenly distributed in the first direction Y, thereby improving the uniformity of heating.

[0047] like Figure 2 and Figure 3 As shown, as an implementation mode, along the first direction Y, the first heating wire group and the second heating wire group are symmetrically arranged (that is, the first heating wire group and the second heating wire group are symmetrically arranged up and down).

[0048] like Figure 2 and Figure 3 As shown, as an implementation mode, in each of two adjacent heating wire groups 100, the trough position N of the innermost heating wire 11 (i.e., the heating wire 11 closest to the center of the mesh heating part 1) in one heating wire group 100 is connected one-to-one with the peak position M of the innermost heating wire 11 in the other heating wire group 100, thereby forming a multi-point connection structure to improve the structural strength of the mesh heating part 1 and further improve the space utilization and heating efficiency of the mesh heating part 1 (of course, in other embodiments, the two may not be connected to each other). In this embodiment, the trough position N of the lowermost heating wire 11 in the upper heating wire group 100 is connected one-to-one with the peak position M of the uppermost heating wire 11 in the lower heating wire group 100.

[0049] like Figure 2 and Figure 3 As shown, as an embodiment, the mesh heating part 1 includes two heating wire groups 100, each heating wire group 100 includes two heating wires 11, that is, the two heating wire groups 100 have a total of four heating wires 11; wherein, the waveform structures of the two upper heating wires 11 are the same, the waveform structures of the two lower heating wires 11 are the same, and the waveform structures of the two upper heating wires 11 are opposite to those of the two lower heating wires 11.

[0050] Of course, in other embodiments, the mesh heating portion 1 can also include more heating wire groups 100, and the multiple heating wire groups 100 are alternately arranged in the order of a first heating wire group, a second heating wire group, a first heating wire group, a second heating wire group...; for example, the mesh heating portion 1 includes four heating wire groups 100, and the four heating wire groups 100 are alternately arranged in the order of a first heating wire group, a second heating wire group, a first heating wire group, and a second heating wire group.

[0051] like Figure 8 As shown, as another embodiment, the mesh heating part 1 includes a heating wire group 100, and the heating wire group 100 includes a plurality of heating wires 11 (four are shown in the figure, but in fact there can be two, three or more heating wires 11), and the waveform structure of each heating wire 11 is the same.

[0052] like Figure 3 and Figure 4 As shown, as an implementation mode, in each heating wire group 100, the peak position M of the first heating wire 11A and the corresponding peak position M on the second heating wire 11B are spaced apart from each other and are not connected to each other, and the trough position N of the first heating wire 11A and the corresponding trough position N on the second heating wire 11B are spaced apart from each other and are not connected to each other.

[0053] like Figures 5 to 7 As shown, as another embodiment, in each heating wire group 100, the peak position M of the first heating wire 11A is connected to the corresponding peak position M on the second heating wire 11B (it should be noted that some of the peak positions M can be connected, or all of the peak positions M can be connected), and / or, the trough position N of the first heating wire 11A is connected to the corresponding trough position N on the second heating wire 11B (it should be noted that some of the trough positions N can be connected, or all of the trough positions N can be connected), thereby forming a multi-point connection structure to improve the structural strength of the mesh heating part 1, and further improve the space utilization and heating efficiency of the mesh heating part 1. At the same time, since the peak positions M and / or the trough positions N of the first heating wire 11A and the second heating wire 11B are connected, the structural stability of the mesh heating part 1 can be guaranteed. For example, during assembly, when the mesh heating part 1 of the heating structure is bent to form a structure as shown in the figure, the mesh heating part 1 is connected to the corresponding trough position M of the first heating wire 11A and the second heating wire 11B. Fig.11 In the cylindrical structure shown, it is possible to ensure that the spacing between the first heating wire 11A and the second heating wire 11B and / or the spacing between the first electrical connection portion 111 and the second electrical connection portion 112 remains basically unchanged, thereby ensuring that the resistance value and heating efficiency of the heating wire do not change, thereby ensuring the consistency of the product and the uniformity of heating; while other types of double heating wires can easily change the size of the spacing between the heating wires during the assembly process, thereby causing the resistance value and heating efficiency of the double heating wire to change.

[0054] like Figure 5As shown, as an implementation mode, in the two heating wire groups 100, the peak position M of the first heating wire 11A in the upper heating wire group 100 is connected to the peak position M of the second heating wire 11B through the first extension portion 114, while the trough position N of the first heating wire 11A in the upper heating wire group 100 is not connected to the trough position N of the second heating wire 11B; the peak position M of the first heating wire 11A in the lower heating wire group 100 is not connected to the peak position M of the second heating wire 11B, while the trough position N of the first heating wire 11A in the lower heating wire group 100 is connected to the trough position N of the second heating wire 11B through the second extension portion 115.

[0055] like Figure 6 As shown, as another embodiment, in the two heating wire groups 100, the peak position M of the first heating wire 11A in the upper heating wire group 100 is not connected to the peak position M of the second heating wire 11B, while the trough position N of the first heating wire 11A in the upper heating wire group 100 is connected one-to-one with the trough position N of the second heating wire 11B through the second extension portion 115; the peak position M of the first heating wire 11A in the lower heating wire group 100 is connected one-to-one with the peak position M of the second heating wire 11B through the first extension portion 114, while the trough position N of the first heating wire 11A in the lower heating wire group 100 is not connected to the trough position N of the second heating wire 11B.

[0056] like Figure 7 As shown, as another embodiment, in the two heating wire groups 100, the peak position M of the first heating wire 11A in the upper heating wire group 100 is connected to the peak position M of the second heating wire 11B through the first extension part 114, and the trough position N of the first heating wire 11A in the upper heating wire group 100 is connected to the trough position N of the second heating wire 11B through the second extension part 115; the peak position M of the first heating wire 11A in the lower heating wire group 100 is connected to the peak position M of the second heating wire 11B through the first extension part 114, and the trough position N of the first heating wire 11A in the lower heating wire group 100 is connected to the trough position N of the second heating wire 11B through the second extension part 115. Of course, in other embodiments, other combinations can also be used.

[0057] like Figures 2 to 4As shown, as an embodiment, the first electrode portion 21 and the second electrode portion 22 are both planar sheet structures, and the first electrode portion 21 and the second electrode portion 22 are both extended along the first direction Y, and along the second direction X, the first electrode portion 21 and the second electrode portion 22 are symmetrically arranged (that is, the first electrode portion 21 and the second electrode portion 22 are symmetrically arranged left and right), and the upper and lower ends of the first electrode portion 21 and the second electrode portion 22 are respectively flush.

[0058] like Figures 2 to 4 As shown, as an embodiment, each heating unit 110 also includes a third electrical connection part 113, which is connected between the first electrical connection part 111 and the second electrical connection part 112 (that is, the third electrical connection part 113 is located at the connection position of the first electrical connection part 111 and the second electrical connection part 112), and the third electrical connection part 113 is located at the peak position M or the trough position N of the heating wire 11. In each heating wire group 100, the third electrical connection portion 113 on the outermost heating wire 11 (i.e., the heating wire 11 farthest from the center of the mesh heating part 1) is a long strip structure (specifically a rectangular structure in this embodiment, of course not limited to this) extending along the first direction Y; and in the two heating wire groups 100, the third electrical connection portion 113 on the outermost heating wire 11 in the upper heating wire group 100 is flush with the upper ends of the first electrode part 21 and the second electrode part 22, and the third electrical connection portion 113 on the outermost heating wire 11 in the lower heating wire group 100 is flush with the lower ends of the first electrode part 21 and the second electrode part 22, that is, the upper and lower ends of the mesh heating part 1 are flush with the upper and lower ends of the first electrode part 21 and the second electrode part 22, respectively, which can not only increase the space utilization rate and heating efficiency of the mesh heating part 1 as much as possible, but also when the heating structure is arranged on the oil-conducting cotton, it can increase its contact area with the oil-conducting cotton, so as to achieve a good supporting effect. In each heating wire group 100, the third electrical connection portion 113 on the inner heating wire 11 (i.e., the heating wire 11 that is closer to the center of the mesh heating portion 1 than the outermost heating wire 11) is a conical structure, so that it can be better inserted into the corresponding empty slot 116 to further improve space utilization.

[0059] As an implementation manner, the mesh heating part 1 and the first electrode part 21 and the second electrode part 22 are integrally formed, and the mesh heating part 1 and the first electrode part 21 and the second electrode part 22 may be made of stainless steel, iron-chromium-nickel or the like.

[0060] like Figure 2 and Figure 3As shown, as an embodiment, the heating structure further includes a first electrode rod 31 and a second electrode rod 32, and the first electrode rod 31 and the second electrode rod 32 are respectively connected to the first electrode portion 21 and the second electrode portion 22 (specifically, they can be connected by welding), and the first electrode rod 31 and the second electrode rod 32 are respectively used to connect to the positive and negative electrodes of the power supply. The first electrode rod 31 and the second electrode rod 32 are both extended along the first direction Y, and the first electrode rod 31 and the second electrode rod 32 extend in the same direction (of course, the first electrode rod 31 and the second electrode rod 32 can also extend in different directions, for example, in opposite directions), and the first electrode rod 31 and the second electrode rod 32 are respectively connected to the surface on the same side of the first electrode portion 21 and the second electrode portion 22.

[0061] like Figure 2 and Figure 3 As shown, as an embodiment, the mesh heating part 1 is a flat plate structure as a whole, and the mesh heating part 1 with a flat plate structure can be set on a porous ceramic body, etc. Of course, in other embodiments, the mesh heating part 1 can also be bent to form a cylindrical structure, and the mesh heating part 1 with a cylindrical structure can be set on an oil-conducting cotton or an air heating pipe, etc.

[0062] like Figures 9 to 11 As shown, an embodiment of the present invention further provides an electronic smoking device, comprising the above-mentioned heating structure and a heated component, wherein the mesh heating portion 1 of the heating structure is in contact with the heated component.

[0063] like Figures 9 to 11 As shown, as an embodiment, the electronic cigarette device is a steam-type electronic cigarette device (i.e., an electronic cigarette device that generates smoke by heating the smoke oil by electric heating), and the heated part is the oil-conducting cotton 44. The oil-conducting cotton 44 is a hollow cylindrical structure, and the mesh heating part 1 of the heating structure is bent to form a cylindrical structure, and the mesh heating part 1 is arranged on the inner wall of the oil-conducting cotton 44 (of course, in other embodiments, the mesh heating part 1 of the heating structure can also be arranged on the outer wall of the oil-conducting cotton 44), and the first electrode rod 31 and the second electrode rod 32 of the heating structure extend out of the oil-conducting cotton 44. The mesh heating part 1 can heat the smoke oil on the oil-conducting cotton 44 to generate smoke (when the mesh heating part 1 is powered on and heated, the smoke oil on the oil-conducting cotton 44 can be heated and atomized at the contact position between the mesh heating part 1 and the oil-conducting cotton 44 to generate smoke).

[0064] like Figures 9 to 11As shown, as an embodiment, the electronic cigarette device further includes an atomizer tube 43, which is a hollow tubular structure. The atomizer tube 43 is made of a heat-conducting material (the atomizer tube 43 can be a steel tube). The oil-conducting cotton 44 is arranged in the atomizer tube 43. The outer wall of the oil-conducting cotton 44 is in contact with the inner wall of the atomizer tube 43. The first electrode rod 31 and the second electrode rod 32 of the heating structure extend out of the atomizer tube 43. The electronic cigarette device further includes a shell 4, in which an oil storage cotton 41 is arranged. The oil storage cotton 41 stores tobacco oil. The oil storage cotton 41 is a hollow cylindrical structure. The atomizer tube 43 is arranged in the oil storage cotton 41. The side wall of the atomizer tube 43 is provided with a through hole 431 for the tobacco oil to pass through.

[0065] Specifically, in the present embodiment, the atomizer tube 43, the oil-conducting cotton 44 and the heating structure constitute a heating component. The atomizer tube 43 can support the oil-conducting cotton 44 on the one hand, and can preheat the oil storage cotton 41 on the other hand. That is, when the heating structure is energized, a part of the heat generated by the heating structure can be transferred to the oil storage cotton 41 through the oil-conducting cotton 44 and the atomizer tube 43 in turn, so that the oil on the oil storage cotton 41 is preheated, thereby promoting the oil on the oil storage cotton 41 to flow to the oil-conducting cotton 44 through the through hole 431 on the atomizer tube 43, thereby improving the atomization efficiency.

[0066] like Figures 9 to 11 As shown, as an embodiment, the electronic cigarette device also includes an air duct 42, which is a hollow tubular structure (the air duct 42 can be a glass fiber tube), and the air duct 42 is arranged in the oil storage cotton 41, and a flue 421 is arranged in the air duct 42. The air duct 42 is arranged above the atomizing tube 43, and the top of the atomizing tube 43 is inserted into the bottom of the air duct 42. The electronic cigarette device also includes a suction nozzle 5, which is connected to the top of the shell 4, and the flue 421 in the air duct 42 is connected to the suction nozzle 5. When the mesh heating part 1 of the heating structure heats the oil on the oil guide cotton 44 to generate smoke, the smoke can enter the suction nozzle 5 through the inner cavity of the atomizing tube 43 and the flue 421 in the air duct 42 for the user to inhale.

[0067] like Figures 9 to 11 As shown, as an embodiment, a power supply 6 is further provided in the shell 4, and the power supply 6 is located below the oil storage cotton 41, and the first electrode rod 31 and the second electrode rod 32 of the heating structure are electrically connected to the positive and negative poles of the power supply 6 respectively.

[0068] like Figures 9 to 11 As shown, as an embodiment, the bottom of the housing 4 is provided with an opening, and the electronic smoking device further comprises a bottom cover 45, which is connected to the bottom opening of the housing 4 to seal the housing 4. The bottom cover 45 is provided with an air inlet 451 for external air to enter the housing 4.

[0069] As another embodiment, the electronic cigarette device is a heat-not-burn electronic cigarette device (i.e., an atomizer that heats tobacco products by electric heating to generate smoke. The specific structure and principle of the heat-not-burn electronic cigarette device can refer to the prior art), the heated part is a hollow tube with a hollow structure (not shown), and the mesh heating part 1 of the heating structure is arranged on the inner wall or outer wall of the hollow tube (at this time, the mesh heating part 1 is bent to form a cylindrical structure). The hollow tube is an air heating tube for heating air, that is, the cold air is first heated by the hollow tube, and then the heated hot air is used to heat the cigarette (not shown) to generate smoke. Alternatively, the hollow tube is a cigarette heating tube for accommodating cigarettes, that is, when in use, the cigarette is inserted into the hollow tube, and the surrounding of the cigarette is directly heated by the hollow tube to generate smoke.

[0070] As another embodiment, the electronic cigarette device is a steam type electronic cigarette device, the heated part is a porous ceramic body (not shown), and the mesh heating part 1 of the heating structure is arranged on the surface of the porous ceramic body (in this case, the mesh heating part 1 can be a flat plate structure). When in use, the smoke oil stored in the electronic cigarette device can be guided to the porous ceramic body, and when the mesh heating part 1 is powered on and heated, the smoke oil on the porous ceramic body can be heated and atomized at the contact position between the mesh heating part 1 and the porous ceramic body to generate smoke.

[0071] The heating structure provided in this embodiment redesigns the shape and arrangement of the mesh heating part 1, and sets the peak position M of each heating wire 11 in the heating wire group 100 in a one-to-one correspondence, and sets the trough position N of each heating wire 11 in the heating wire group 100 in a one-to-one correspondence, that is, the waveform structure of each heating wire 11 in the heating wire group 100 is the same; and in the heating wire group 100, each peak position M of the first heating wire 11A is located in the corresponding empty groove 116 on the second heating wire 11B, and each trough position N of the second heating wire 11B is located in the corresponding empty groove 116 on the first heating wire 11A, that is, the two adjacent heating wires 11 are a structure of mutual insertion and interlocking, thereby improving the space utilization rate of the mesh heating part 1; under the condition of the same size and the same resistivity as the existing mesh heating wire, the mesh heating part 1 of the heating structure has a larger effective area, a higher heating efficiency, and a larger contact area with the e-liquid, so the atomization efficiency is higher, and the taste of the e-liquid can be fully atomized and restored, and it is beneficial to save space and reduce production costs.

[0072] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
