An atomization component is provided in the electronic cigarette, and the e-liquid is heated and atomized through the atomization component. Figure 1 1 is a schematic diagram of the structure of an atomization assembly 100' of an electronic atomization device in the prior art.

The center of the oil guide body 110' has an atomization channel 111', and the heating net 120' is arranged in the atomization channel 111'. The smoke oil is sucked from the periphery of the oil guide body 110' to the center of the oil guide body 110', and then heated and atomized by the heating net 120' in the center of the oil guide body 110'. Figure 1 During inhalation, the airflow in the atomization channel 111' flows from bottom to top, taking away the aerosol formed by atomization through the heating net 120'.

Figure 1 and Figure 2 The heating net 120' is wound and arranged in the atomizing channel 111'. It is limited by the lateral space in the atomizing channel 111', that is, the diameter of the heating net 120' after being wound is limited. Figure 3 yes Figure 1 and Figure 2 The structure diagram of the existing heating network 120' is shown in FIG. Figure 3 As shown, the heating wire 121' on the heating net 120' extends horizontally, and the current is Figure 3 The heat from one end of the heating net 120' flows to the other end. Due to the limitation of the horizontal space in the atomizing channel 111', and because the heating wire of the existing heating net 120' extends horizontally, the length of the heating wire 121' is limited, the heating wire 121' is short, and the heating effect is poor.

[0049] In order to facilitate the understanding of the present application, the present application is described in more detail below in conjunction with the accompanying drawings and specific implementation methods.

[0050] The present application embodiment provides an atomization assembly. Figure 4 and Figure 5 As shown, the atomization assembly 100 includes an oil guide body 110 and a heating net 120. The oil guide body 110 can be made of oil guide cotton. Figure 5 As shown, the oil guide body 110 has a first end A and a second end B opposite to each other in the longitudinal direction. Figure 5 As shown by the middle arrow, the suction airflow in the oil guiding body 110 flows in the longitudinal direction, and the suction airflow flows from one end to the other end of the oil guiding body 110 in the longitudinal direction. Figure 5 In the embodiment shown, the atomizer assembly 100 is placed vertically, with the first end A at the top and the second end B at the bottom. The "vertical direction" mentioned above refers to the vertical direction. Figure 5 In the vertical direction, the suction airflow flows from the second end B to the first end A, and flows from bottom to top. In other embodiments, if the atomizer assembly 100 is placed horizontally or at an angle, the airflow direction and the "longitudinal direction" mentioned above are also adjusted accordingly. For example, if the atomizer assembly 100 is placed horizontally, the longitudinal direction refers to the horizontal direction, and the suction airflow flows from one end of the oil guide body 110 to the other end along the horizontal direction.

[0051] like Figure 5 As shown, the heating net 120 is arranged in the oil guide body 110. The heating net 120 is as follows when it is not assembled. Figure 7 In the unfolded state shown in FIG. 1 , the heating net 120 is in a flat net shape. When the heating net 120 is assembled with the oil guide body 110, as shown in FIG. Figure 5 and Figure 6 As shown, the heating net 120 is wound in the oil-conducting cotton. Of course, in other embodiments, the heating net 120 can also be directly installed in the oil-conducting body 110 without being wound.

[0052] like Figure 6 and 7 As shown, the heating network 120 has a positive terminal a and a negative terminal b, combined with Figure 5 , the positive terminal a is close to the first end A of the oil-conducting body 110, and the negative terminal b is close to the second end B of the oil-conducting body 110. That is, the positive terminal a is on the top and the negative terminal b is on the bottom. Of course, in other optional embodiments, the positive terminal a and the negative terminal b can also be swapped. Figure 7 As shown, the heating net 120 includes a heating wire 121, which extends longitudinally between the positive terminal a and the negative terminal b. After the heating net 120 is powered on, current flows from the positive terminal a through the heating wire 121 to the negative terminal b.

[0053] In the prior art, as described in the background art, the heating wire 121′ is arranged in the horizontal direction, and the current runs in the horizontal direction. Since the horizontal space of the atomization channel 111′ in the oil guide body 110′ is very small, the horizontal size of the heating net 120′ is limited, that is, the length of the heating wire 121′ is limited, thereby affecting the heating effect. In the embodiment of the present application, the heating wire 121 is arranged in the longitudinal direction, and the positive terminal a and the negative terminal b of the heating net 120 are respectively located at the two ends in the longitudinal direction. The heating wire 121 extends in the longitudinal direction between the positive terminal a and the negative terminal b, and the current runs in the longitudinal direction. In this way, the longitudinal space in the atomization channel 111 of the oil guide body 110 can be fully utilized to arrange the heating wire 121, so that the length of the heating wire 121 can be set longer, thereby improving the heating effect.

[0054] In one embodiment, if Figure 5 and Figure 6 As shown, the oil guide body 110 is provided with an atomizing channel 111 which penetrates the oil guide body 110 in the longitudinal direction, and the heating net 120 is wound and attached to the side wall of the atomizing channel 111, as shown in FIG. Figure 6 As shown, the central axis R of the heating net 120 is arranged along the longitudinal direction. Figure 5 and Figure 6 In the embodiment shown, the atomizer assembly 100 is arranged vertically, and the longitudinal direction is the vertical direction. The heating wire 121 also extends in the longitudinal direction, that is, the extension direction of the heating wire 121 is substantially parallel to the central axis R of the heating net 120. Figure 3 As shown, the heating wire 121 ′ extends in the transverse direction and is combined with Figure 1 and Figure 3 The central axis direction of the heating net 120 ′ is along the longitudinal direction, so the extending direction of the heating wire 121 ′ in the prior art is perpendicular to the central axis direction of the heating net 120 ′.

[0055] Furthermore, the conventional oil-conducting body 110' includes an inner layer and an outer layer, the inner layer is closely attached to the heating net 120', and the outer layer is attached to the atomizing support tube 130'. The inner layer is arranged with vertical stripes, so that the heat of the heating path is diffused longitudinally, which can enhance the longitudinal oil conduction; the outer layer is arranged with horizontal stripes, so as to speed up the horizontal oil conduction rate and transmit it to the inner layer. The conventional oil-conducting body 110' is equipped with horizontal stripes and vertical stripes, which affects the final oil conduction effect and slows down the oil supply speed. Figure 4 , Figure 5 The oil guide body 110 also adopts the structure of an inner layer and an outer layer. The inner layer is close to the heating network 120, and the outer layer is close to the atomization support tube 130. The inner layer and the outer layer are both arranged in horizontal stripes. The inner layer is arranged in horizontal stripes because the heat in the heating path is diffused horizontally, which can enhance the horizontal oil conduction. The inner layer and the outer layer are both matched with horizontal stripes, and the oil conduction is smoother, so as to provide a better oil supply solution for atomization.

[0056] like Figure 7As shown, the heating wire 121 of the heating net 120 is provided with heat conducting wires 122 extending along both sides of the heating wire 121. The heat conducting wires 122 help to transfer the heat of the heating wire 121 to other parts of the oil guiding body 110, so that the oil guiding body 110 is heated evenly, and the smoke oil is atomized more evenly.

[0057] In the embodiment of the present application, the heating wire 121 can be provided in multiple pieces, and providing multiple heating wires 121 can improve the heating effect. Figure 7 In the embodiment shown, two heating wires 121 are provided. It is understood that in other embodiments, the heating wires 121 may be 3, 4, or even more. Fig.11 As shown, three heating wires 121 are provided. Figure 7 and Fig.11 As shown, a plurality of heating wires 121 are arranged in parallel and spaced apart, and the heat conducting wires 122 between adjacent heating wires 121 are connected to each other to enhance the strength of the heating network 120. Figure 7 As shown, the heat-conducting wires 122 between adjacent heating wires 121 are connected to each other so that the heating wires 121 and the heat-conducting wires 122 together form a mesh.

[0058] like Figure 7 As shown, the heating network 120 further includes a positive electrode connection portion 123, a negative electrode connection portion 124, a positive electrode pin 125 and a negative electrode pin 126. The positive electrode connection portion 123 and the negative electrode connection portion 124 are respectively disposed at the positive terminal a and the negative terminal b of the heating network 120. Figure 7 As shown, the positive electrode connection part 123 and the negative electrode connection part 124 both include a cross bar 1201 and a longitudinal bar 1202 connected to each other, the cross bar 1201 is connected to the heating wire 121 and the corresponding end of the cross bar 1201, and the longitudinal bar 1202 is connected to the corresponding positive electrode pin 125 or negative electrode pin 126. In other words, Figure 7 As shown, the crossbar 1201 of the positive electrode connection part 123 connects the end of the heating wire 121 corresponding to the positive terminal a, and the vertical bar 1202 of the positive electrode connection part 123 is connected to the positive electrode pin 125; the crossbar 1201 of the negative electrode connection part 124 connects the end of the heating wire 121 corresponding to the negative terminal b, and the vertical bar 1202 of the negative electrode connection part 124 is connected to the negative electrode pin 126. The positive electrode connection part 123 and the negative electrode connection part 124 are configured to include the crossbar 1201 and the vertical bar 1202 to facilitate the connection of the heating wire 121 and the pin.

[0059] The heating wire 121, the heat-conducting wire 122, the positive electrode connection part 123 and the negative electrode connection part 124 can be integrally formed and formed into a mesh by etching and other processes. The integrally formed mesh can be made of materials such as nickel-chromium alloy, stainless steel, etc., or other materials with large resistance, which is convenient for heating after power-on. The heating wire 121, the heat-conducting wire 122, the positive electrode connection part 123 and the negative electrode connection part 124 are integrally formed and then welded to the pins. The positive pin 125 and the negative pin 126 are made of materials with low resistance, such as pure nickel, which is convenient for conductivity.

[0060] In some embodiments, Figure 7 and Fig. 9 As shown, the horizontal bar 1201 and the vertical bar 1202 of each connection part (positive connection part 123 and negative connection part 124) form a "7" shape, and the positive pin 125 and the negative pin 126 are connected to the corresponding vertical bar 1202 from the same end. The horizontal bar 1201 and the vertical bar 1202 are formed into a "7" shape, so that the positive pin 125 and the negative pin 126 can be connected to the corresponding vertical bar 1202 from the same end of the heating network 120, as shown in FIG. Figure 5 As shown, the positive electrode pin 125 and the negative electrode pin 126 can be led downward to connect to the battery assembly 300 below. Fig. 9 The positive electrode connection portion 123 and the negative electrode connection portion 124 form a positive "7"-shaped structure, which can also be Figure 7 The middle negative electrode connecting portion 124 also forms an inverted "7"-shaped structure.

[0061] Or, if Fig.10 As shown, the horizontal bar 1201 and the vertical bar 1202 of each connecting part can also form a "T" shape, and the positive electrode pin 125 and the negative electrode pin 126 are connected to the corresponding vertical bar 1202 from different ends. Fig.10 As shown, the positive pin 125 and the negative pin 126 are led out from the upper and lower ends respectively.

[0062] In one embodiment, as shown in FIG7 , the heating wire 121 is bent and extended in a wave shape to extend the length of the heating wire 121. The heat-conducting wire 122 can be connected to each bend of the heating wire 121, so that the mesh structure is more solid and also facilitates etching.

[0063] like Figures 4 to 6 As shown, the atomizer assembly 100 also includes an atomizer support tube 130. The atomizer support tube 130 is hollow, forming an air flow channel that runs through the upper and lower ends of the atomizer support tube. The oil guide body 110 is arranged in the atomizer support tube 130, and an oil guide hole 131 is arranged on the tube wall of the atomizer support tube 130. The oil guide hole 131 is arranged corresponding to the oil guide body 110, so that the smoke oil outside the atomizer support tube 130 can flow into the oil guide body 110 from the oil guide hole 131.

[0064] The present application also provides an electronic atomization device. Fig.12 As shown, the electronic atomization device 10 in the embodiment of the present application is an electronic cigarette. In other optional embodiments, the electronic atomization device 10 may also be other types of electronic atomization devices, such as a medical electronic atomization device.

[0065] like Fig.12 As shown, the electronic cigarette 10 includes the above-mentioned atomizer assembly 100, and also includes a shell 200 and a battery assembly 300. A nozzle 201 is provided at one end of the shell 200 in the longitudinal direction. An oil storage chamber 202 and an air flow channel are provided in the shell 200, and the atomizer assembly 100 is arranged in the air flow channel. The air flow channel extends in the longitudinal direction, and the atomizer assembly 100 is arranged in the air flow channel, so that the smoke oil can be atomized to form an aerosol. The oil storage chamber 202 is used to store the smoke oil. In the embodiment of the present application, as shown in FIG. Fig.12 As shown, the smoke oil is stored in the oil storage cotton 210, and the oil storage cotton 210 is placed in the oil storage chamber 202. In other embodiments, the smoke oil can also be directly injected into the oil storage chamber 202 without using the oil storage cotton 210 to store the smoke oil.

[0066] The battery assembly 300 is disposed in the housing 200, the heating network 120 is electrically connected to the battery assembly 300, and the battery assembly 300 supplies power to the heating network 120. Fig.12 As shown, the battery assembly 300 is disposed below the atomizer assembly 100 . In other optional embodiments, the battery assembly 300 may also be disposed on one side of the atomizer assembly 100 .

[0067] In the present application embodiment, Fig.12 As shown, when the electronic cigarette 10 is used, the user draws inhalation from the mouthpiece 201, as shown in FIG. Fig.12 As shown by the dotted arrow, the external airflow enters the battery compartment 203 from the air inlet hole at the bottom of the housing 200, and then enters the atomization channel 111. The airflow carries away the aerosol formed by heating and atomization of the atomization component 100, and then flows out from the mouthpiece.

[0068] The present application embodiment also provides a heating network 120. Figure 7 As shown, the heating net 120 is used in an electronic atomization device, such as an electronic cigarette. The heating net 120 includes a heating wire 121, a positive electrode connection part 123, a negative electrode connection part 124, a positive electrode pin 125 and a negative electrode pin 126.

[0069] The heating wire 121 is arranged to extend in the longitudinal direction. The longitudinal direction refers to the direction of the airflow flowing through the heating net 120, that is, Figure 7 The direction is shown by the straight arrow.

[0070] The positive connection part 123 and the negative connection part 124 are respectively arranged at two ends of the heating wire 121 in the longitudinal direction. After the heating network 120 is powered on, the current flows from the positive connection part 123 through the heating wire 121 to the negative connection part 124 . Figure 7 In the figure, the positive electrode connection part 123 is on the top and the negative electrode connection part 124 is on the bottom. In other optional embodiments, the negative electrode connection part 124 can also be on the top and the positive electrode connection part 123 can also be on the bottom.

[0071] like Figure 7 As shown, the positive pin 125 and the negative pin 126 are connected to the positive connection part 123 and the negative connection part 124 respectively, and the positive pin 125 and the negative pin 126 are connected to the corresponding positive connection part 123 and the negative connection part 124 along a direction parallel to the longitudinal direction. Figure 7 As shown, the positive electrode pin 125 and the negative electrode pin 126 are connected to the positive electrode connection part 123 and the negative electrode connection part 124 along the longitudinal direction from the bottom end of the heating network 120, and the positive electrode connection part 123 and the negative electrode connection part 124 are connected to the heating network 120. Figure 5 , so that the heating wire 121 can be arranged to extend in the longitudinal direction, and at the same time, the two pins can also be led out along the bottom end and connected to the battery assembly 300 below the heating network 120. In the present application, the extension direction of the heating wire 121 is the same as the lead-out direction of the pins. As mentioned above, this is different from the prior art in which the lead-out direction of the pins (positive pin 125' and negative pin 126') is perpendicular to the extension direction of the heating wire 121'. In the present application, the heating wire 121 is arranged to extend in the longitudinal direction, so that the heating wire 121 is longer and the heating effect is better.

[0072] There are many ways to realize that the two pins are led out in a direction parallel to the longitudinal direction. For details, see the above embodiment. The positive electrode connection part 123 and the negative electrode connection part 124 can be set to include a horizontal bar 1201 and a vertical bar 1202. The horizontal bar 1201 and the vertical bar 1202 can form a "7" shape structure or a "T" shape to achieve, such as Figure 7 , Fig.10 and Fig.11 shown.
