[0002] Electronic cigarette devices generally use heating components to heat the atomized matrix to form atomized gas, replacing traditional tobacco. The atomized matrix is ​​stored in the oil storage bin of the electronic cigarette device, generally stored in liquid form or absorbed in the oil storage cotton. The atomized matrix is ​​stored in the oil storage cotton, which has good sealing performance but poor fluidity.

[0003] When multiple atomizer cores are used, the amount of smoke can be increased and the taste can be improved. However, when multiple atomizer cores are provided, due to the characteristics of the heating wire of the atomizer core, a gap is formed between the positive electrode and the negative electrode, causing the heating wire to heat unevenly in the circumferential direction, so that the atomization matrix of the oil storage cotton surrounding the atomizer core is consumed unevenly under certain circumstances (such as continuous long-term inhalation), causing the heating wire to burn, or too much atomization matrix remaining in the oil storage cotton causing waste.

[0033] Figures 1 to 8 It is the accompanying drawing of the utility model.

[0034] This embodiment provides an oil cup assembly 10 with multiple atomizer cores, see Figure 1 , 2 , including an oil cup shell 11, at least two atomizer cores 12 disposed therein, and an oil storage cotton 13 disposed inside the oil cup shell 11. The atomizer core 12 includes a heating wire 121, which is a cylindrical structure and a mesh structure when laid out. A gap 122 extending from one end to the other end is disposed on the side of the heating wire 121. The gap 122 is formed due to the characteristics of the properties of the heating wire 121 itself, that is, a physical interval between the positive and negative electrodes of the heating wire 121 to avoid short circuit.

[0035] The heating wire 121 is unfolded into a mesh structure, one end of which is connected to the positive lead 127, and the other end is connected to the negative lead 128. A certain interval needs to be set between the positive and negative electrodes to prevent short circuit. Therefore, after the mesh heating wire 121 is rolled into a cylindrical shape, one end where the positive lead 127 is set and one end where the negative lead 128 is set need to be separated by a certain distance, and this distance forms the above-mentioned gap 122. Since the heating wire 121 is formed with the gap 122, there will be a gap in the heating range of the cylindrical mesh heating wire 121, and the gap will extend from the upper end to the lower end of the heating wire 121. When the cylindrical heating wire 121 is powered on to generate heat, in the circumferential direction, the heat generated at the position where the gap 122 is present is less than the heat generated at other positions, so the heating wire 121 is uneven in the circumferential heating area.

[0036] Preferably, the ratio of the curvature of the gap 122 to the curvature of the heating wire 121 is 0.1 to 1. The curvature of the gap 122 cannot be set too large. The maximum ratio of the curvature of the gap to the curvature of the heating wire 121 is 1. If the curvature is too large, the heat in the circumferential direction in the atomization channel is uneven, which may easily lead to uneven consumption of the atomization matrix by the oil storage cotton 13. If the gap 122 is set too small, it is easy to cause a short circuit between the positive lead 127 and the negative lead 128.

[0037] Since the gap formed by the gap 122 on the heating wire 121 has uneven heat in the heating area and other parts, the atomizing matrix on the oil-conducting cotton 124 corresponding to the gap is heated and atomized at a low speed, and the fluidity of the atomizing matrix in the oil storage cotton 13 is slow, and the atomizing matrix in the area outside the gap 122 corresponding to the oil storage cotton 13 cannot be replenished in time to the area of ​​the oil storage cotton 13 corresponding to the gap 122, and the atomizing matrix of the oil storage cotton 13 corresponding to the gap 122 is consumed slowly. Therefore, the heating area of ​​the heating wire 121 is heated unevenly, resulting in uneven consumption of the atomizing matrix of the oil storage cotton 13. If the atomizing matrix of a certain part of the oil storage cotton 13 is consumed faster, and the atomizing matrix of another part is consumed slower, it takes a certain time difference for the atomizing matrix to flow back from the slower consumption area to the faster consumption area. In the continuous suction process, the area where the atomizing matrix is ​​consumed faster will be burned, while the area where the atomizing matrix is ​​consumed slower is still completely consumed, which will cause waste. Especially in the atomization device with multiple atomization cores 12, the above phenomenon is more common. Therefore, if multiple atomization cores 12 are arranged in the oil cup assembly 10, it is necessary to have a reasonable layout of the positions of the atomization cores 12 so that the atomization matrix of the oil storage cotton 13 can be consumed evenly.

[0038] Arranging multiple atomizer cores 12 in the same oil cup assembly can not only increase the atomization amount of the suction, but also prevent excessive carbon accumulation in a single atomizer core, which affects the taste of the smoke. Therefore, many electronic cigarettes currently arrange multiple atomizer cores 12 in the same oil cup assembly.

[0039] Multiple atomizer cores 12 are arranged in the same oil cup assembly 10 and are in the same oil storage tank, so a certain rule is required to layout the multiple atomizer cores 12. Therefore, there are at least two atomizer cores 12, and the gap 122 of the heating wire 121 corresponds to the center of the figure formed by connecting the centers of the multiple atomizer cores 12 in sequence on the same plane. It can be understood that the center of the figure formed by the center line of the multiple atomizer cores 12, the gap 122 of the heating wire 121 is toward the center of the figure. Since the gap 122 of the heating wire 121 consumes the atomization matrix of the oil storage cotton 13 relatively slowly, the gap 122 is toward the center of the figure formed by connecting the centers of the atomizer cores 12 in sequence. The volume of the oil cup assembly 10 needs to consider compactness, and the volume cannot be designed to be too large, and the distance between the atomizer cores 12 cannot be set too large, and the air outlet end of each atomizer core 12 is connected to the air outlet end of the oil cup assembly 10, and the atomizer cores 12 cannot be set too dispersed. Since the area facing the gap 122 of the heating wire 121 consumes the atomizing matrix more slowly, the area of ​​the oil storage cotton 13 surrounded by the center line of the atomizing core 12 is smaller than the unenclosed area. The gap 122 is the center of the figure formed by the lines connecting the center of the atomizing core 12 in sequence, which can improve the balance of the atomizing matrix consumption in the oil storage cotton 13.

[0040] Preferably, the volume ratio of the area of ​​the oil storage cotton 13 surrounded by the center line of the atomizer core 12 to the area not surrounded is 0.2 to 0.5. Since the area surrounded by the center line of the atomizer core 12 is the area facing the gap 122 of the heating wire 121, the atomization substrate is consumed slowly, while the area not surrounded is the area facing away from the gap 122 of the heating wire 121, and the atomization substrate is consumed quickly, so the volume ratio of the area surrounded by the center line of the atomizer core 12 is smaller than that of the area not surrounded, which is conducive to the balanced consumption of the atomization substrate and avoids the waste of the atomization substrate.

[0041] For details, please refer to Figures 2 to 5 If there are two atomizer cores 12, the gaps 122 of the heating wires 121 of the two atomizer cores 12 face each other, which can be understood as the direction of the line connecting the centers of the two atomizer cores 12 is the direction of the gaps 122 of the two heating wires 121, and the gaps 122 of the two heating wires 121 face each other. When there are two atomizer cores 12, the two atomizer cores 12 are arranged side by side or on the diagonal line of the oil cup assembly 10, and the center distance between the two atomizer cores 12 is less than or one third of the width of the oil cup assembly 10.

[0042] See also Figure 6, if there are three atomizer cores 12, the area enclosed by the lines connecting the centers of the three atomizer cores 12 in the same plane is a triangle, and the gaps 122 of the three electric heating wires 121 face the center of the triangle. In order to make the structure compact and reduce the volume of the oil cup assembly 10, when there are three atomizer cores 12, the three atomizer cores 12 are arranged in a triangle, and the three atomizer cores 12 are approximately the same distance from the oil cup shell 11 of the oil cup assembly 10. Preferably, for the convenience of design, processing, installation, etc., the center lines of the three atomizer cores 12 in the cross section form an equilateral triangle, so the direction of the gap 122 is the midpoint of the perpendicular line of the triangle. In other embodiments, the three atomizer cores 12 can be arranged side by side, and the gap 122 of the electric heating wire 121 of the middle atomizer core 12 faces the opposite direction of the gaps 122 of the electric heating wires 121 of the other two atomizer cores 12.

[0043] See also Figure 7 If there are four atomizer cores 12, the center lines of the four atomizer cores 12 on the same plane form a quadrilateral structure, and the gap 122 faces the intersection of the diagonals of the quadrilateral. Preferably, for the convenience of design, processing, installation, etc., the center lines of the four atomizer cores 12 form a regular quadrilateral (such as a rectangle or a square) in the cross section, and the gap 122 faces the position of the intersection of the diagonals of the regular quadrilateral. Preferably, the distance from each atomizer core 12 to the oil cup shell 11 is the same, so that the atomization matrix in the oil cup assembly 10 can be consumed evenly. More preferably, the four atomizer cores 12 are symmetrically arranged in pairs in the oil cup assembly 10.

[0044] See also Figure 8 If the number of the atomizer cores 12 is five, six, seven or even more, the gap 122 is also oriented toward the intersection of the diagonals of the regular polygon in the cross section.

[0045] Preferably, the center of the atomizer core 12 is formed by connecting lines in sequence on the same cross section and the center of the oil cup assembly coincides with each other. The atomizer core 12 is laid out according to the center of the oil cup assembly, which can improve the convenience of design, processing and installation. The oil cup assembly is a regular shape, such as a circle, a regular polygon, etc., the center of which is the center of the circle or the intersection of the diagonals. The atomizer core 12 is installed around the center of the circle or the intersection of the diagonals, and the gaps 122 of the heating wire 121 are all facing the center of the circle or the intersection of the diagonals.

[0046] See also Figures 2 to 4The oil cup shell 11 is formed with a closed cavity 111, and the oil storage cotton 13 is arranged in the closed cavity 111. The oil storage cotton 13 is provided with a mounting hole 131. The atomizer core 12 is arranged in the mounting hole 131, and the atomizer core 12 is in contact with the oil storage cotton 13, so that the atomization matrix of the oil storage cotton 13 can penetrate into the atomizer core 12. One end of the mounting hole 131 is connected to the air inlet end of the oil cup assembly 10, and the other end is connected to the air outlet end of the oil cup assembly 10. The atomizer core 12 is arranged behind the mounting hole 131 to form an atomization channel, and the air outlet end of the oil cup assembly 10 is connected to the suction nozzle, so after the atomizer core 12 heats and atomizes the atomization matrix in the oil cup assembly 10, it can be sucked out from the suction nozzle.

[0047] The length of the atomizer core 12 is shorter than the length of the mounting hole 131. Therefore, if the atomizer core 12 is placed in the mounting hole 131, the oil storage cotton 13 will be exposed in the atomization channel, which will cause the atomized matrix of the oil storage cotton 13 to leak into the atomization channel. Therefore, an extension tube 129 is provided at the end of the atomizer core 12 facing the nozzle, and the extension tube 129 is also provided in the mounting hole 131. The extension tube 129 can prevent the atomized matrix in the oil storage cotton 13 from leaking into the atomization channel.

[0048] Among them, see Figures 2 to 4 , the atomizer core 12 also includes a mounting tube 123, and an oil-conducting cotton 124 arranged on the inner wall of the mounting tube 123. The oil-conducting cotton 124 is a cylindrical structure, and the heating wire 121 is arranged on the inner wall of the cylindrical structure. The mounting tube 123 serves as a mounting bracket for the atomizer core 12, and the oil-conducting cotton 124 is arranged on the inner wall of the mounting tube 123, and then the heating wire 121 is installed on the inner wall of the oil-conducting cotton 124. Therefore, after the atomizer core 12 is arranged in the closed cavity 111, the atomization matrix of the oil storage cotton 13 can penetrate into the heating wire 121 through the oil-conducting cotton 124. It can be understood that the mounting tube 123, the oil-conducting cotton 124 and the heating wire 121 are arranged in sequence from the outside to the inside. The oil-conducting cotton 124 completely wraps the heating wire 121 on its inner wall, so that the heating wire 121 can be completely immersed in the atomization matrix of the oil-conducting cotton 124 to avoid dry burning or burning.

[0049] The side wall of the mounting tube 123 is provided with an oil inlet window 125, and the number of the oil inlet windows 125 can be set to be multiple. The oil inlet window 125 is circumferentially arranged on the side of the mounting tube 123, and the oil guide cotton 124 is completely covered on the oil inlet window 125, that is, the oil inlet window 125 is connected to the surface of the oil guide cotton 124. In the length direction of the mounting tube, the oil inlet window 125 cannot exceed the length of the oil guide cotton 124 to avoid oil leakage on the atomizer core 12.

[0050] Preferably, since the heating wire 121 is completely disposed in the oil-conducting cotton 124, the direction of the gap 122 of the heating wire 121 cannot be distinguished when the atomizer core 12 is installed. Therefore, marks corresponding to the gap 122 of the heating wire 121 are provided at both ends or the outside of the installation tube 123, so that the positioning and installation of the atomizer core 12 are more convenient.

[0051] See also Figures 2 to 4 , the oil-conducting cotton 124 is provided with a connecting portion 126. The setting position of the connecting portion 126 is staggered with the gap 122 of the electric heating wire 121. Since the oil-conducting cotton 124 is formed by curling the cotton body with oil-conducting properties, a joint-type connecting portion is formed. In order to make the atomized matrix penetrate more evenly, after the electric heating wire 121 is installed on the oil-conducting cotton 124, the position of the connecting portion 126 is staggered with the position of the gap 122. Preferably, the connecting portion 126 is located on the side opposite to the gap 122.

[0052] See also Figures 2 to 4 The oil cup shell 11 includes a shell 112, a first seal 113 arranged at the lower end of the shell 112, and a second seal 114 arranged at the upper end of the shell 112. The lower end of the atomizer core 12 is fixed to the first seal 113. Specifically, the lower end of the mounting tube 123 is plugged and fixed in the socket 115 provided in the first seal 113 to fix the atomizer core 12. One end face of the first seal 113 is inserted into the shell 112. The cross-sectional area of ​​the first seal 113 can basically represent the cross-sectional area of ​​the oil cup assembly. The layout position of the socket 115 is basically the layout position of the atomizer core 12 in the oil cup assembly. The socket 115 is arranged around the center of the first seal 113, so that the atomizer core 12 can be arranged in space. After the atomizer core 12 is fixed, the oil storage cotton 13 is sleeved outside the atomizer core 12.

[0053] Preferably, a connecting tube is further provided on the outside of the atomizer core 12, or one end of the atomizer core 12 close to the second sealing member 114 is connected to the gas outlet end of the oil cup assembly through the connecting tube. When the connecting tube is provided on the outside of the atomizer core 12, the connecting tube is completely wrapped around the outside of the atomizer core 12, and one end of the connecting tube is connected to the jack 115 of the first sealing member 113, and the other end is connected to the second sealing member 114, and an oil hole is provided on the outside of the connecting tube at a position corresponding to the oil inlet window 125.

[0054] An electronic cigarette device includes the above-mentioned oil cup assembly 10, a battery, and a circuit board. The battery provides power to the atomization core 12, and the circuit board controls the entire device.

[0055] Compared with the prior art, due to its own structural characteristics, after the atomizer core 12 is installed on the oil cup assembly, the heating wire 121 of the utility model has a gap 122 that faces the center of the atomizer core 12 and is formed by connecting the center of the atomizer core 12 in the same plane, so that the atomizer matrix in the oil storage cotton 13 is consumed evenly, the taste of the smoke is maintained, and the waste of the atomizer matrix is ​​avoided.

[0056] The above examples are only used to further illustrate the technical content of the utility model, so that readers can understand it more easily, but it does not mean that the implementation methods of the utility model are limited to this. Any technical extension or re-creation made based on the utility model is protected by the utility model. The protection scope of the utility model shall be based on the claims.
