Description

Technical Field

[0001] This application belongs to the field of atomization technology, and in particular relates to an atomizing core and its manufacturing method. Background Technology

[0002] The atomizer coil is part of an atomizing device. It typically includes an wicking element and a heating element. The wicking element absorbs the e-liquid within the atomizing device, while the heating element heats and atomizes the e-liquid on the wicking element. In some atomizer coils, the heating element has a channel within it, and its peripheral wall has through-holes communicating with this channel. The wicking element covers the outer surface of the heating element. After being heated and atomized by the heating element, the e-liquid on the wicking element flows through the through-holes into the channel, mixes with the air flowing within the channel, and then exits the atomizing device for the user to inhale.

[0003] However, the oil guide expands after absorbing the atomizing liquid, which can compress the heating element and cause it to deform, narrowing the channels inside the heating element and thus increasing the suction resistance. Summary of the Invention

[0004] The purpose of this application is to provide an atomizing core and its manufacturing method, which aims to solve the technical problem in the prior art where the oil guide component of the atomizing core expands after absorbing the atomizing liquid and compresses the heating element, which easily leads to deformation of the heating element, narrowing of the internal channel of the heating element, and thus increasing the suction resistance.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: an atomizing core, including a support assembly, an oil guide, and a heating element. A channel is formed inside the support assembly, and multiple through holes communicating with the channel are provided on the peripheral sidewall of the support assembly. The oil guide covers the outer peripheral surface of the support assembly, and the heating element is disposed on the support assembly and located between the outer peripheral surface of the support assembly and the inner peripheral surface of the oil guide to separate the support assembly and the oil guide. After the oil on the oil guide is heated and atomized by the heating element, it can enter the channel through the through holes.

[0006] Compared with the prior art, the beneficial effects of the atomizing core provided in this application are as follows: the heating element can heat and atomize the oil on the oil guide, and after atomization, the oil can enter the channel of the support assembly through the through hole and mix with the air flowing in the channel for the user to inhale; by placing the heating element between the outer peripheral surface of the support assembly and the inner peripheral surface of the oil guide to separate the support assembly and the oil guide, it is possible to avoid the oil guide absorbing oil and expanding, which would directly compress the support assembly, making the support assembly less prone to deformation, effectively preventing the channel from narrowing, ensuring smooth airflow in the channel, and reducing suction resistance.

[0007] Furthermore, the support assembly includes a frame, a first fixing member and a second fixing member, a channel and a through hole are provided on the frame, an oil guide member is covered on the outer peripheral surface of the support, the first fixing member and the second fixing member are respectively located at both ends of the oil guide member and are respectively connected to both ends of the frame, and a heating element is connected between the first fixing member and the second fixing member and is located between the outer peripheral surface of the frame and the inner peripheral surface of the oil guide member.

[0008] Furthermore, both the first and second fixing members protrude at least partially from the outer peripheral surface of the frame. The first fixing member has a first fixing hole at the part protruding from the outer peripheral surface of the frame, and the second fixing member has a second fixing hole at the part protruding from the outer peripheral surface of the frame. The heating element passes through the first fixing hole and the second fixing hole.

[0009] Furthermore, the first fixing member includes a first connecting part and a first fixing part. The first connecting part is located inside the oil guide member and is connected between the first fixing part and the frame. The first fixing part protrudes from the outer peripheral surface of the frame, and the first fixing hole is provided in the first fixing part.

[0010] The second fastener includes a second connecting part and a second fixing part. The second connecting part is located inside the oil guide and is connected between the second fixing part and the frame. The second fixing part protrudes from the outer peripheral surface of the frame, and the second fixing hole is provided in the second fixing part.

[0011] Furthermore, the first connecting part and the second connecting part are located at both ends of the channel, respectively.

[0012] Furthermore, there are multiple first fixing holes and multiple second fixing holes. The heating element is a flexible structure. After passing through at least two first fixing holes and at least two second fixing holes, the heating element is connected end to end to form a closed loop structure.

[0013] Furthermore, both the first and second fixing members are metal electrodes, and the heating element is electrically connected to both the first and second fixing members. The heating element can generate heat after being energized.

[0014] This application also provides a method for manufacturing an atomizing core, comprising the following steps: providing a support assembly, a heating element, and an oil guide component; the support assembly includes a frame, a first fixing component, and a second fixing component; a channel is formed within the frame; multiple through holes communicating with the channel are provided on the peripheral sidewall of the frame; the first fixing component and the second fixing component are respectively connected to both ends of the frame; the first fixing component has a first fixing hole, and the second fixing component has a second fixing hole; the heating element is disposed on the outer peripheral surface of the frame and passes through the first fixing hole and the second fixing hole; the oil guide component is wrapped around the outer peripheral surface of the frame and the heating element to obtain the atomizing core.

[0015] The atomizing core manufacturing method provided in this application involves placing a heating element on the outer peripheral surface of a frame, passing through a first fixing hole of a first fixing member and a second fixing hole of a second fixing member, and then covering the outer peripheral surface of the frame and the heating element with an oil guide member, thus obtaining the atomizing core, which is very convenient to manufacture. When in use, the heating element heats and atomizes the oil on the oil guide member. After atomization, the oil enters the channel of the support assembly through the through-hole, mixing with the air flowing in the channel for the user to inhale. By placing the heating element between the outer peripheral surface of the support assembly and the inner peripheral surface of the oil guide member, the support assembly and the oil guide member are separated. This prevents the oil guide member from absorbing oil and expanding, thus avoiding direct pressure on the support assembly. This makes the support assembly less prone to deformation, effectively preventing channel narrowing, ensuring smooth airflow within the channel, and reducing suction resistance.

[0016] This application also provides another method for manufacturing an atomizing core, comprising the following steps: providing a frame, a first fixing member, a second fixing member, a heating element, and an oil guiding member; a channel is formed inside the frame, and multiple through holes communicating with the channel are provided on the peripheral sidewall of the frame; the first fixing member includes a first connecting part and a first fixing part, one end of the first connecting part is connected to the first fixing part, and the first fixing part is provided with a first fixing hole; the second fixing member includes a second connecting part and a second fixing part, one end of the second connecting part is connected to the second fixing part, and the second fixing part is provided with a second fixing hole; inserting the other end of the first connecting part and the other end of the second connecting part into the two ends of the channel respectively; placing the heating element on the outer peripheral surface of the frame and passing through the first fixing hole and the second fixing hole; and covering the outer peripheral surface of the frame and the heating element with the oil guiding member to obtain the atomizing core.

[0017] The method for manufacturing the atomizing core provided in this application involves inserting the first connecting portion of the first fixing member and the second connecting portion of the second fixing member into both ends of the channel, respectively. The heating element is placed on the outer circumferential surface of the frame, passing through the first fixing hole of the first fixing member and the second fixing hole of the second fixing member. Then, the oil guide member is wrapped around the outer circumferential surface of the frame and the heating element, thus obtaining the atomizing core. This method is very convenient to manufacture. When in use, the heating element heats and atomizes the oil on the oil guide member. After atomization, the oil enters the channel of the support assembly through the through-hole, mixing with the air flowing within the channel for the user to inhale. By placing the heating element between the outer circumferential surface of the support assembly and the inner circumferential surface of the oil guide member, the support assembly and the oil guide member are separated. This prevents the oil guide member from absorbing oil and expanding, thus avoiding direct pressure on the support assembly. This makes the support assembly less prone to deformation, effectively preventing channel narrowing, ensuring smooth airflow within the channel, and reducing suction resistance.

[0018] Furthermore, there are multiple heating elements, first fixing holes, and second fixing holes. Multiple heating elements are disposed on the outer peripheral surface of the frame and are respectively fixed in the corresponding first fixing holes and corresponding second fixing holes after passing through different first fixing holes and different second fixing holes.

[0031] Example 1

[0032] like Figures 1 to 4 As shown, this application embodiment provides an atomizing core 100, which is assembled in the cavity of an atomizing tube 200. The atomizing tube 200 is assembled in the housing of an atomizing device. The extending direction of the atomizing core 100 is consistent with the extending direction of the atomizing tube 200. The atomizing core 100 can absorb the oil in the atomizing device and heat and atomize the oil to generate an aerosol. The air entering the atomizing device can flow into the atomizing tube 200 from one end, mix with the aerosol generated by the atomizing core 100, and then flow out of the atomizing tube 200 from the other end, and then out of the atomizing device for the user to inhale.

[0033] Furthermore, such as Figure 1As shown, the atomizing tube 200 has several oil inlet holes 201 on its peripheral sidewall. The oil inlet holes 201 are connected to the cavity of the atomizing tube 200. The oil in the atomizing device can enter the cavity of the atomizing tube 200 through the oil inlet holes 201 and then be absorbed and atomized by the atomizing core 100.

[0034] like Figure 2 As shown, the atomizing core 100 includes a support assembly 10, an oil guide 20, and a heating element 30. A channel 111 is formed inside the support assembly 10, and a plurality of through holes 112 communicating with the channel 111 are provided on the peripheral sidewall of the support assembly 10. The oil guide 20 covers the outer peripheral surface of the support assembly 10, and the heating element 30 is disposed on the support assembly 10 and located between the outer peripheral surface of the support assembly 10 and the inner peripheral surface of the oil guide 20, so as to separate the support assembly 10 and the oil guide 20.

[0035] Compared with the prior art, the beneficial effects of the atomizing core 100 provided in this application embodiment are as follows: the heating element 30 can heat and atomize the oil on the oil guide 20. After atomization, the oil can enter the channel 111 of the support assembly 10 through the through hole 112 and mix with the air flowing in the channel 111 for the user to inhale. By placing the heating element 30 between the outer peripheral surface of the support assembly 10 and the inner peripheral surface of the oil guide 20 to separate the support assembly 10 and the oil guide 20, it is possible to prevent the oil guide 20 from expanding after absorbing the oil and directly compressing the support assembly 10, making the support assembly 10 less prone to deformation, effectively preventing the channel 111 from narrowing, ensuring smooth airflow in the channel 111, reducing suction resistance, and improving the user's experience.

[0036] In addition, by placing the heating element 30 between the outer peripheral surface of the bracket assembly 10 and the oil guide 20 to separate the bracket assembly 10 and the oil guide 20, it is possible to prevent the oil guide 20 from absorbing oil and expanding, thus directly compressing the bracket assembly 10. This also prevents the oil on the oil guide 20 from not having enough time to be fully atomized and directly entering the channel 111 through the through hole 112, thereby preventing the user from inhaling the oil and improving the user experience.

[0037] Specifically, during use, the oil in the atomizing device enters the cavity of the atomizing tube 200 through the oil inlet 201 and is absorbed by the oil guide 20. The heating element 30 heats and atomizes the oil on the oil guide 20 to generate an aerosol. The aerosol enters the channel 111 through the through hole 112. The air entering the housing enters the atomizing tube 200 from one end and then enters the channel 111 from one end. After mixing with the aerosol in the channel 111, the air flows out of the channel 111 from the other end and then out of the atomizing tube 200 from the other end, and finally out of the atomizing device for the user to inhale.

[0038] like Figure 2 and Figure 3 As shown, the bracket assembly 10 includes a frame 11, a first fixing member 12 and a second fixing member 13. A channel 111 and a through hole 112 are provided on the frame 11. An oil guide member 20 covers the outer peripheral surface of the frame 11. The first fixing member 12 and the second fixing member 13 are respectively located at both ends of the oil guide member 20 and are respectively connected to both ends of the frame 11. A heating element 30 is connected between the first fixing member 12 and the second fixing member 13 and is located between the outer peripheral surface of the frame 11 and the inner peripheral surface of the oil guide member 20. In this embodiment, by placing the first fixing member 12 and the second fixing member 13 at both ends of the oil guide member 20 and connecting them to both ends of the frame 11, the heating element 30 connected between the first fixing member 12 and the second fixing member 13 spans both ends of the frame 11 in the length direction and spans both ends of the oil guide member 20 in the length direction. On the one hand, the heating element 30 can better withstand the pressure applied when the oil guide member 20 expands, providing stronger support, making the frame 11 less prone to deformation, effectively preventing the narrowing of the channel 111 inside the frame 11, ensuring smooth airflow inside the channel 111, and reducing suction resistance. On the other hand, it can increase the heating area of ​​the oil guide member 20, making the oil guide member 20 more uniformly heated in the length direction and enhancing the oil atomization effect.

[0039] like Figure 2 and Figure 3 As shown, the frame 11 is in the shape of a cylindrical tube. This cylindrical shape facilitates manufacturing and reduces costs. Furthermore, the cylindrical channel 111 formed within the frame 11 is regular in shape, promoting smooth airflow, reducing suction resistance, and improving user experience. Additionally, the cylindrical frame 11 facilitates the installation of the oil-guiding component 20, which can be a cylindrical oil-guiding cotton with good liquid absorption capacity.

[0040] The frame 11 is made of high-temperature resistant plastic. The frame 11 is made of high-temperature resistant plastic, such as PEEK, PEI and PC. On the one hand, it is easy to manufacture, which helps to reduce costs. On the other hand, the frame 11 is not easily deformed when heated, which effectively prevents the channel 111 from narrowing, ensures smooth airflow in the channel 111, reduces suction resistance, and improves the user experience.

[0041] like Figure 2 and Figure 3 As shown, multiple through holes 112 are evenly distributed on the peripheral sidewalls of the frame 11. This even distribution of through holes 112 allows the oil on the oil guide 20 to quickly and smoothly enter the channels 111 of the frame 11 from any direction after atomization. The shape of the through holes 112 is not limited and can be circular, square, rhomboid, triangular, parallelogram, or irregular shapes, etc.

[0042] like Figure 2 As shown, the first fixing member 12 is provided with an air inlet 121, and the second fixing member 13 is provided with an air outlet 131. The air inlet 121 and the air outlet 131 are respectively connected to both ends of the channel 111. In use, the air entering the atomizing device enters the atomizing tube 200 from one end, then enters the channel 111 through the air inlet 121, mixes with the aerosol in the channel 111, and flows out of the channel 111 through the air outlet 131, and then flows out of the atomizing tube 200 from the other end, and then out of the atomizing device for the user to inhale.

[0043] like Figure 2 and Figure 3 As shown, both the first fixing member 12 and the second fixing member 13 protrude at least partially from the outer peripheral surface of the frame 11. The portion of the first fixing member 12 protruding from the outer peripheral surface of the frame 11 has a first fixing hole 122, and the portion of the second fixing member 13 protruding from the outer peripheral surface of the frame 11 has a second fixing hole 132. The heating element 30 passes through the first fixing hole 122 and the second fixing hole 132. By opening the first fixing hole 122 on the first fixing member 12 and the second fixing hole 132 on the second fixing member 13, the heating element 30 is connected between the first fixing member 12 and the second fixing member 13, which has the advantages of simple structure, easy manufacturing, convenient assembly, and facilitates automated assembly. The first fixing hole 122 is located on the part of the first fixing member 12 that protrudes from the outer peripheral surface of the frame 11, and the second fixing hole 132 is located on the part of the second fixing member 13 that protrudes from the outer peripheral surface of the frame 11. Thus, when the heating element 30 passes through the first fixing hole 122 and the second fixing hole 132, the heating element 30 is located on the outer peripheral surface of the frame 11.

[0044] like Figure 3 As shown, there are multiple heating elements 30, first fixing holes 122, and second fixing holes 132. These multiple heating elements 30 are spaced apart along the circumference of the frame 11, and each passes through a different first fixing hole 122 and a different second fixing hole 132. The spaced arrangement of multiple heating elements 30 along the circumference of the frame 11 serves two purposes: firstly, it enhances the protective effect of the heating elements 30 on the frame 11, making the frame 11 less prone to deformation, effectively preventing the narrowing of the channel 111 within the frame 11, ensuring smooth airflow within the channel 111, and reducing suction resistance; secondly, it increases the contact area between the heating elements 30 and the oil guide 20, making the oil guide 20 more evenly heated in the circumferential direction and enhancing the oil atomization effect.

[0045] like Figures 2 to 4As shown, the first fixing member 12 includes a first connecting part 123 and a first fixing part 124. The first connecting part 123 is located inside the oil guide member 20 and is connected between the first fixing part 124 and the frame 11. The first fixing part 124 protrudes from the outer peripheral surface of the frame 11, and a first fixing hole 122 is provided in the first fixing part 124. The second fixing member 13 includes a second connecting part 133 and a second fixing part 134. The second connecting part 133 is located inside the oil guide member 20 and is connected between the second fixing part 134 and the frame 11. The second fixing part 134 protrudes from the outer peripheral surface of the frame 11, and a second fixing hole 132 is provided in the second fixing part 134.

[0046] Specifically, the first connecting part 123 and the second connecting part 133 are located at both ends of the channel 111, respectively. The first connecting part 123 and the second connecting part 133, respectively located at both ends of the channel 111, provide support for the channel 111, effectively preventing deformation and narrowing of the channel 111, ensuring smooth airflow within the channel 111, reducing suction resistance, and improving the user experience. In this embodiment, the first fixing member 12 and the frame 11 are separate structures, that is, the first connecting part 123 and the frame 11 are separate structures, and the second fixing member 13 and the frame 11 are separate structures, that is, the second connecting part 133 and the frame 11 are separate structures. During assembly, the first connecting part 123 and the second connecting part 133 are respectively inserted into both ends of the channel 111, thus forming the support assembly 10, which has a simple structure and is easy to assemble. Furthermore, since the frame 11, the first fixing member 12, and the second fixing member 13 are separate structures, they can be replaced individually without requiring overall replacement, which helps reduce production costs.

[0047] like Figure 3 and Figure 4 As shown, both the first connecting part 123 and the first fixing part 124 are annular structures, and both the second connecting part 133 and the second fixing part 134 are annular structures. The inner hole of the first connecting part 123 is connected to the inner hole of the first fixing part 124 and together they form an air inlet 121. The inner hole of the second connecting part 133 is connected to the inner hole of the second fixing part 134 and together they form an air outlet 131. The outer ring diameters of the first fixing part 124 and the second fixing part 134 are both larger than the outer diameter of the frame 11, thus protruding from the outer circumferential surface of the frame 11.

[0048] like Figure 3 and Figure 4As shown, there are multiple first fixing holes 122 and second fixing holes 132. The heating element 30 has a flexible structure. After passing through two first fixing holes 122 and two second fixing holes 132, the heating element 30 is connected end to end to form a closed loop structure. After passing through two first fixing holes 122 and two second fixing holes 132, the heating element 30, the first fixing element 12, and the second fixing element 13 are connected end to end to form a closed loop structure, thereby firmly binding the heating element 30, the first fixing element 12, and the second fixing element 13 together. This ensures that the heating element 30 is stably fixed between the first fixing element 12 and the second fixing element 13. Therefore, when the oil guide element 20 absorbs oil and expands, the heating element 30 can better withstand the pressure exerted by the oil guide element 20, making the frame 11 less prone to deformation under pressure. This effectively prevents the channel 111 inside the frame 11 from narrowing, ensures smooth airflow in the channel 111, reduces suction resistance, and improves the user experience.

[0049] Before assembly, the heating element 30 is filamentous. During assembly, one end of the heating element 30 is sequentially passed through one first fixing hole 122, another first fixing hole 122, one second fixing hole 132, and another second fixing hole 132 before being connected to the other end of the heating element 30 to form a closed-loop structure. Alternatively, in specific operation, the heating element 30 can be passed through one second fixing hole 132, another second fixing hole 132, one first fixing hole 122, and another first fixing hole 122 before being connected to the other end of the heating element 30; the order is not limited here. The heating element 30 can specifically be a metal heating wire, and the two ends of the heating element 30 are connected by welding to form a stable closed-loop structure. To further improve the stability of the structure, the heating element 30 can be welded and fixed in the first fixing hole 122 and the second fixing hole 132.

[0050] Specifically, such as Figure 3 and Figure 4 As shown, the heating element 30 includes a first segment 31, a second segment 32, a third segment 33, and a fourth segment 34 connected end to end. The first segment 31 is located on the side of the first fixing member 12 away from the second fixing member 13, and the third segment 33 is located on the side of the second fixing member 13 away from the first fixing member 12. One end of the second segment 32 and one end of the fourth segment 34 are respectively provided with two different first fixing holes 122 and are respectively connected to the two ends of the first segment 31. The other end of the second segment 32 and the other end of the fourth segment 34 are respectively provided with two different second fixing holes 132 and are respectively connected to the two ends of the third segment 33. The second segment 32 and the fourth segment 34 are both located between the outer peripheral surface of the frame 11 and the inner peripheral surface of the oil guide member 20.

[0051] Assuming the first fixing member 12 and the second fixing member 13 are arranged vertically, with the first fixing member 12 located below the second fixing member 13, and the first segment 31 located on the side of the first fixing member 12 away from the second fixing member 13, the first fixing member 12 can restrict the first segment 31 from moving upward, that is, it can restrict the heating element 30 from moving upward as a whole. The third segment 33 is located on the side of the second fixing member 13 away from the first fixing member 12, and the second fixing member 13 can restrict the third segment 33 from moving downward, that is, it can restrict the heating element 30 from moving downward as a whole. In addition, the first fixing member 12 can restrict the second segment 32 and the fourth segment 34 from moving along... The radial movement of the first fixing hole 122 and the second fixing member 13 can restrict the radial movement of the second segment 32 and the fourth segment 34 along the second fixing hole 132. In this way, the heating element 30 is limited in multiple directions, ensuring that the heating element 30 is stably fixed between the first fixing member 12 and the second fixing member 13. Thus, when the oil guide member 20 absorbs oil and expands, the heating element 30 can better withstand the pressure applied by the expansion of the oil guide member 20, making the frame 11 less prone to deformation under pressure, effectively preventing the channel 111 in the frame 11 from narrowing, ensuring smooth airflow in the channel 111, reducing suction resistance, and improving the user experience.

[0052] Depending on the positions of the first fixing hole 122 and the second fixing hole 132, the first segment 31, the second segment 32, the third segment 33 and the fourth segment 34 of the heating element 30 can be arranged into a square, a rectangle, a parallelogram and a trapezoid, etc., without limitation.

[0053] Specifically, such as Figure 3 and Figure 4 As shown, there are eight first fixing holes 122, which are evenly spaced along the circumference of the first fixing member 12. Every two adjacent first fixing holes 122 form a group. There are also eight second fixing holes 132, which are evenly spaced along the circumference of the second fixing member 13 and are directly opposite to the eight first fixing holes 122. Every two adjacent second fixing holes 132 form a group. There are four heating elements 30, and each heating element 30 is provided with a set of first fixing holes 122 and a set of second fixing holes 132. The first segment 31 and the third segment 33 of the heating element 30 are parallel to each other, and the second segment 32 and the fourth segment 34 of the heating element 30 are parallel to each other. The first segment 31, the second segment 32, the third segment 33 and the fourth segment 34 together form a rectangle.

[0054] Of course, the heating element 30 can also have two or more first fixing holes 122 and two or more second fixing holes 132. For example, the first fixing holes 122 in the second segment 32 and the first fixing holes 122 in the fourth segment 34 are spaced apart by two first fixing holes 122. The first segment 31 is serpentine, alternately winding around the opposite sides of the first fixing member 12, and passing through the two first fixing holes 122 between the second segment 32 and the fourth segment 34, thus achieving four first fixing holes 122 for the heating element 30. Similarly, the second fixing holes 132 in the second segment 32 and the second fixing holes 132 in the fourth segment 34 are spaced apart by two second fixing holes 132. The third segment 33 is serpentine, alternately winding around the opposite sides of the second fixing member 13, and passing through the two first fixing holes 122 between the second segment 32 and the fourth segment 34, thus achieving four second fixing holes 132 for the heating element 30. Similarly, the heating element 30 can also be provided with six, eight, ten or more multiples of two first fixing holes 122 and second fixing holes 132.

[0055] In this embodiment, both the first fixing member 12 and the second fixing member 13 are metal electrodes. The heating element 30 is electrically connected to the first fixing member 12 and the second fixing member 13, and the heating element 30 can generate heat after being energized. On the one hand, the first fixing member 12 and the second fixing member 13 serve to fix the heating element 30. On the other hand, as metal electrodes, the first fixing member 12 and the second fixing member 13 allow an external power supply to be electrically connected to the heating element 30 through them. In specific operation, the positive terminal of the power supply is connected to the first fixing member 12, and the negative terminal is connected to the second fixing member 13. The current starts from the positive terminal, passes through the first fixing member 12, the heating element 30, and the second fixing member 13 in sequence, and returns to the negative terminal. The energized heating element 30 can generate heat to heat and atomize the oil on the oil guide member 20. Of course, the positive terminal of the power supply can also be reversed and connected to the second fixing member 13, and the negative terminal can be reversed and connected to the first fixing member 12. Both the first fixing member 12 and the second fixing member 13 can be welded to the heating element 30, which can improve the structural strength and ensure good electrical conductivity.

[0056] When there are multiple heating elements 30, and these heating elements 30 are spaced apart circumferentially along the frame 11, on the one hand, the multiple heating elements 30 can enhance the protection of the frame 11, making the frame 11 less prone to deformation, effectively preventing the narrowing of the channel 111 inside the frame 11, ensuring smooth airflow within the channel 111, and reducing suction resistance. On the other hand, a single power supply can simultaneously power each spaced heating element 30 through the first fixing member 12 and the second fixing member 13, eliminating the need for multiple power supplies for multiple heating elements 30, making circuit construction simple and easy. In specific operation, the positive terminal of the power supply is connected to the first fixing member 12, and the negative terminal is connected to the second fixing member 13. Current enters the first fixing member 12 from the positive terminal, then splits into each parallel heating element 30, then converges at the second fixing member 13, and finally returns to the negative terminal. Of course, the positive terminal of the power supply can also be reversed and connected to the second fixing member 13, and the negative terminal can be reversed and connected to the first fixing member 12.

[0057] In addition, multiple heating elements 30 are connected in parallel, independent of each other and do not affect each other. Even if one heating element 30 breaks, the other heating elements 30 can still work normally, thereby improving the reliability of operation.

[0058] Specifically, for a single heating element 30, the first segment 31 of the heating element 30 is welded to the first fixing member 12, the third segment 33 of the heating element 30 is welded to the second fixing member 13, and the second segment 32 and the fourth segment 34 of the heating element 30 are also connected in parallel. In operation, the positive terminal of the power supply is connected to the first fixing member 12, and the negative terminal is connected to the second fixing member 13. The current flows from the positive terminal, through the first fixing member 12 into the first segment 31, then splits at both ends of the first segment 31 into the second and fourth segments 34, then converges at the third segment 33, and finally returns to the negative terminal through the second fixing member 13. Alternatively, the positive terminal of the power supply can be connected to the second fixing member 13, and the negative terminal can be connected to the first fixing member 12.

[0059] Example 2

[0060] The difference between this embodiment and Embodiment 1 is that: Figure 5 As shown, the first fixing member 12 and the frame 11 are an integral structure, that is, the first connecting part 123 and the frame 11 are an integral structure, and the second fixing member 13 and the frame 11 are an integral structure, that is, the second connecting part 133 and the frame 11 are an integral structure. The frame 11, the first fixing member 12 and the second fixing member 13 are an integral structure. On the one hand, it is easy to manufacture and has low manufacturing cost. On the other hand, it has good physical properties, the overall structure is firm and reliable and not easy to deform, effectively preventing the narrowing of the channel 111 inside the frame 11, ensuring smooth airflow in the channel 111 and reducing suction resistance.

[0061] The rest of this embodiment is the same as that in Embodiment 1. Features not explained in this embodiment are explained using the methods in Embodiment 1, and will not be repeated here.

[0062] Example 3

[0063] This application also provides a method for manufacturing an atomizing core 100, including the following steps:

[0064] A support assembly 10, a heating element 30, and an oil guide 20 are provided. The support assembly 10 includes a frame 11, a first fixing member 12, and a second fixing member 13. A channel 111 is formed inside the frame 11, and multiple through holes 112 communicating with the channel 111 are provided on the peripheral sidewall of the frame 11. The first fixing member 12 and the second fixing member 13 are respectively connected to both ends of the frame 11. The first fixing member 12 has a first fixing hole 122, and the second fixing member 13 has a second fixing hole 132. The heating element 30 is disposed on the outer peripheral surface of the frame 11 and passes through the first fixing hole 122 and the second fixing hole 132. The oil guide 20 is covered on the outer peripheral surface of the frame 11 and the heating element 30 to obtain an atomizing core 100. The obtained atomizing core 100 can be assembled into an atomizing tube 200.

[0065] The method for manufacturing the atomizing core 100 provided in this application embodiment involves placing the heating element 30 on the outer peripheral surface of the frame 11 and passing through the first fixing hole 122 of the first fixing element 12 and the second fixing hole 132 of the second fixing element 13. Then, the oil guide element 20 is wrapped around the outer peripheral surface of the frame 11 and the heating element 30, thus obtaining the atomizing core 100, which is very convenient to manufacture. The atomizing core 100, when in use, uses the heating element 30 to heat and atomize the oil on the oil guide 20. After atomization, the oil enters the channel 111 of the support assembly 10 through the through hole 112, mixing with the air flowing in the channel 111 for the user to inhale. By placing the heating element 30 between the outer peripheral surface of the support assembly 10 and the inner peripheral surface of the oil guide 20, the support assembly 10 and the oil guide 20 are separated. This prevents the oil guide 20 from expanding after absorbing oil and directly compressing the support assembly 10, making the support assembly 10 less prone to deformation, effectively preventing the channel 111 from narrowing, ensuring smooth airflow in the channel 111, reducing suction resistance, and improving the user experience. In this embodiment, the frame 11, the first fixing member 12, and the second fixing member 13 are integrated into a single structure.

[0066] Specifically, the heating element 30 is disposed on the outer peripheral surface of the frame 11 and passes through the first fixing hole 122 and the second fixing hole 132, so that the heating element 30 can be fixed in the first fixing hole 122 and the second fixing hole 132.

[0067] For example, the specific operation process of fixing the heating element 30 in the first fixing hole 122 and the second fixing hole 132 is as follows: First, the heating element 30 is inserted into the first fixing hole 122 and the second fixing hole 132, and then glue is piled in the first fixing hole 122 and the second fixing hole 132 so that the heating element 30 is bonded and fixed in the first fixing hole 122 and the second fixing hole 132.

[0068] For example, firstly, the first fixing hole 122 and the second fixing hole 132 are respectively passed through the two ends of the heating element 30. Then, the blocks are set at both ends of the heating element 30. The outer dimensions of the blocks are larger than the diameters of the first fixing hole 122 and the second fixing hole 132. One block is stuck on the side of the first fixing member 12 away from the second fixing member 13, and the other block is stuck on the side of the second fixing member 13 away from the first fixing member 12. In this way, the heating element 30 is stably fixed between the first fixing member 12 and the second fixing member 13.

[0069] For example, the heating element 30 is bendable. During manufacturing, one end of the heating element 30 can be inserted into the first fixing hole 122 from the end near the second fixing hole 132, and then bend after exiting from the other end of the first fixing hole 122. It extends in the opposite direction and wraps around the outside of the first fixing member 12, and then bends again and inserts into the first fixing hole 122. This process is repeated so that one end of the heating element is bound to the first fixing member 12. Similarly, the other end of the heating element 30 can be inserted into the second fixing hole 132 from the end near the first fixing hole 122, and then bend after exiting from the other end of the second fixing hole 132. It extends in the opposite direction and wraps around the outside of the second fixing member 13, and then bends again and inserts into the second fixing hole 132. This process is repeated so that the heating element 30 is bound to the second fixing member 13. This ensures that the heating element 30 is stably fixed between the first fixing member 12 and the second fixing member 13.

[0070] For example, the heating element 30 has a flexible structure. After passing through two first fixing holes 122 and two second fixing holes 132, the heating element 30 is connected end to end to form a closed loop structure, thus ensuring that the heating element 30 is stably fixed between the first fixing member 12 and the second fixing member 13. Specifically, the two ends of the heating element 30 are connected by welding.

[0071] Example 4

[0072] This application provides a method for manufacturing an atomizing core 100, including the following steps: providing a frame 11, a first fixing member 12, a second fixing member 13, a heating element 30, and an oil guiding member 20; the frame 11 has a channel 111 formed inside it, and the peripheral sidewall of the frame 11 has a plurality of through holes 112 communicating with the channel 111; the first fixing member 12 includes a first connecting part 123 and a first fixing part 124; one end of the first connecting part 123 is connected to the first fixing part 124; the first fixing part 124 has a first fixing hole 122; the second fixing part 124 has a first fixing hole 122; and the second fixing part 124 has a first fixing hole 122. The fixing component 13 includes a second connecting part 133 and a second fixing part 134. One end of the second connecting part 133 is connected to the second fixing part 134, and the second fixing part 134 is provided with a second fixing hole 132. The other ends of the first connecting part 123 and the second connecting part 133 are respectively inserted into the two ends of the channel 111. The heating element 30 is disposed on the outer peripheral surface of the frame 11 and passes through the first fixing hole 122 and the second fixing hole 132. The oil guide 20 is covered on the outer peripheral surface of the frame 11 and the heating element 30 to obtain the atomizing core 100. The obtained atomizing core 100 can be assembled into the atomizing tube 200 of the atomizing device.

[0073] The method for manufacturing the atomizing core 100 provided in this application involves inserting the first connecting portion 123 of the first fixing member 12 and the second connecting portion 133 of the second fixing member 13 into both ends of the channel 111, placing the heating element 30 on the outer peripheral surface of the frame 11, and passing through the first fixing hole 122 of the first fixing portion 124 and the second fixing hole 132 of the second fixing portion 134. Then, the oil guiding member 20 is wrapped around the outer peripheral surface of the frame 11 and the heating element 30, thus obtaining the atomizing core 100, which is very convenient to manufacture. The atomizing core 100, when in use, uses the heating element 30 to heat and atomize the oil on the oil guide 20. After atomization, the oil can enter the channel 111 of the support assembly 10 through the through hole 112, mix with the air flowing in the channel 111, and be inhaled by the user. By placing the heating element 30 between the outer peripheral surface of the support assembly 10 and the inner peripheral surface of the oil guide 20, the support assembly 10 and the oil guide 20 are separated. This prevents the oil guide 20 from expanding after absorbing oil and directly compressing the support assembly 10, making the support assembly 10 less prone to deformation, effectively preventing the channel 111 from narrowing, ensuring smooth airflow in the channel 111, reducing suction resistance, and improving the user experience. In this embodiment, the frame 11, the first fixing member 12, and the second fixing member 13 are separate structures.

[0074] Specifically, there are multiple heating elements 30, first fixing holes 122 and second fixing holes 132. Multiple heating elements 30 are disposed on the outer peripheral surface of the frame 11, and after passing through different first fixing holes 122 and different second fixing holes 132, the multiple heating elements 30 are fixed in the corresponding first fixing holes 122 and the corresponding second fixing holes 132.

[0075] Exemplarily, the specific operation process of fixing the heating element 30 in the first fixing hole 122 and the second fixing hole 132 is as follows: The heating element 30 is disposed on the outer peripheral surface of the frame 11 and passes through the first fixing hole 122 and the second fixing hole 132, and then the heating element 30 is welded and fixed in the first fixing hole 122 and the second fixing hole 132. In this example, both the first fixing member 12 and the second fixing member 13 are metal electrodes.

[0076] Of course, the heating element 30 can also be fixed in the first fixing hole 122 and the second fixing hole 132 in other ways. For details, please refer to Embodiment 3, which will not be repeated here.
