[0026] The utility model discloses an atomizer core and an atomizer, which are used to solve the technical problem that the traditional atomizer core lacks an exhaust structure in its atomizer support, which easily causes the atomizer core to overheat and become sticky during use of the atomizer, thereby affecting the overall atomization effect and life of the atomizer.

[0027] See also Figure 1 , Figure 1 This is a schematic diagram of the exploded structure of an atomizer core provided in an embodiment of the utility model.

[0028] The utility model provides an atomizer core, comprising an atomizer bracket 2, a composite liquid-conducting cotton 3 and a heating element 4; the atomizer bracket 2 is provided with a accommodating cavity, and a side wall of the atomizer bracket 2 is provided with a liquid inlet hole 23 connected with the accommodating cavity; the composite liquid-conducting cotton 3 is arranged in the accommodating cavity; the composite liquid-conducting cotton 3 comprises an exhaust layer and a liquid-conducting layer, the liquid-conducting layers enclose a heating cavity, the exhaust layer is arranged on a side of the liquid-conducting layer away from the heating cavity, and covers the liquid inlet hole 23; the heating element 4 is arranged in the heating cavity.

[0029] In the embodiment of the utility model, an atomizer core is provided, which is mainly composed of an atomizer bracket 2, a composite liquid-conducting cotton 3 and a heating element 4. The composite liquid-conducting cotton 3 is attached to the inner side of the side wall of the atomizer bracket 2, and the composite liquid-conducting cotton 3 is enclosed in the atomizer bracket 2 to form a hollow heating chamber for accommodating the heating element 4. The composite liquid-conducting cotton 3 includes an exhaust layer 32 and a liquid-conducting layer 31. The liquid-conducting layer 31 can be realized by a multi-layer cotton structure. By wrapping the exhaust layer 32 on the outer side of the liquid-conducting layer 31, as shown in FIG. Figure 5As shown. In order to solve the problem that the atomized liquid is constantly consumed and the outside air cannot enter the liquid tank, a negative pressure will be formed inside the liquid tank, resulting in the atomized liquid being unable to be transmitted normally, and then the phenomenon of insufficient liquid supply will occur, resulting in the problem of dry burning and sticking of the atomizer core. Through the setting of the exhaust layer 32, the structure of the sparse structure cotton can allow the outside air to enter the liquid tank through the exhaust layer. A accommodating cavity is formed inside the atomizer bracket 2, and at least one liquid inlet hole connected to the accommodating cavity is opened on the side wall of the atomizer bracket 2. At the same time, the exhaust layer 32 of the composite liquid-conducting cotton 3 is located on the side away from the heating chamber and covers the liquid inlet hole. When external liquid enters, it penetrates into the liquid-conducting layer 31 through the exhaust layer 32. At this time, the heating element 4 inside the liquid-conducting layer 31 generates heat to complete the atomization of the infiltrated liquid.

[0030] The heating element 4 is composed of a heating sheet 41 and a pin 42. The heating sheet 41 of the heating element 4 is attached to the inner surface of the liquid guide layer 31. At the same time, a base for the pin 42 to be inserted can be provided in the atomizer bracket. The pin 42 extends to the outside through the base 5 at the bottom of the atomizer bracket 2. The pin 42 of the heating element 4 is fixed by the base 5 to ensure the structural stability of the atomizer core.

[0031] It should be noted that the horizontal cross-section of the atomizer core can be circular or other regular shapes for easy production and processing. The heating sheet 41 can be a mesh spiral structure heating element, a mesh heating sheet, a spiral heating wire, a wavy heating element, a mesh heating element, etc.

[0032] In a specific implementation, the manufacturing process of the atomizer core can be as follows:

[0033] First, stack the liquid conducting layer 31 and the exhaust layer 32 from top to bottom to form a composite liquid conducting cotton 3, attach the heating sheet 41 of the heating element 4 to the upper surface of the composite liquid conducting cotton 3, that is, the upper surface of the liquid conducting layer 31, and wrap the attached structure on a cotton wrapping rod jig to enclose it to form a heating chamber, and load it into a cotton cutting jig through the cotton wrapping rod jig, and limit the length of the composite liquid conducting cotton 3 through the cotton cutting jig, and cut off excess composite liquid conducting cotton 3; install the assembly consisting of the composite liquid conducting cotton 3 and the heating element 4 into the appropriate position in the atomizer bracket 2 through the cotton wrapping rod jig, and mark the inner side of the side wall of the atomizer bracket 2; the pin 42 of the heating element 4 needs to be aligned with the groove on the side of the base 5 to facilitate the pin 42 to be led out along the groove; finally, embed the sealing silicone 1 at the top of the atomizer bracket 2.

[0034] Alternatively, if Figure 2As shown, the composite liquid-conducting cotton 3 includes multiple layers of cotton stacked from the inside to the outside, wherein the exhaust layer 32 and the liquid-conducting layer 31 can both be multiple layers, and to improve the atomization exhaust effect, the exhaust cotton of the outermost layer can be set to be a sparse structure cotton, and the density of the exhaust layer 32 is less than that of the liquid-conducting layer 31. In addition, to further improve the liquid-conducting effect, the density of the multiple layers of cotton of the liquid-conducting layer 31 can be increased layer by layer from the outside to the inside.

[0035] It should be noted that the sparse structure cotton refers to cotton with a porous structure. The exhaust layer 32 can be made of wood pulp cotton, seaweed cotton, etc. There is no restriction on the cotton material of the liquid conductive layer 31, which can be the oil conductive cotton material commonly used in the market.

[0036] Among them, when the external liquid enters the composite liquid guide cotton 3, it penetrates from the low-density exhaust cotton to the high-density exhaust cotton, so that the liquid guide rate is effectively increased, providing a stable atomization environment for subsequent atomization, and because the density of the inner layer of exhaust cotton is relatively large, it can also serve the purpose of refining the external liquid, so that the temperature distribution of the heating plate 41 is uniform, the atomization efficiency is improved, and the subsequent user experience is enhanced.

[0037] Optionally, the atomizer core further comprises a sealing silicone 1, the sealing silicone 1 is connected to the top of the atomizer bracket 2, and a first gap 61 exists between the composite liquid-guiding cotton 3 and the sealing silicone 1 along the axial direction of the atomizer core. Figure 3 As shown, the first gap 61 can be 0.5-1mm. When the atomizer core is atomizing, due to the multi-layer exhaust cotton structure of the composite liquid-conducting cotton 3 and the sparse structure cotton on the outermost layer, a certain amount of liquid may overflow into the first gap 61, and the overflowed liquid is blocked by the sealing silica gel 1, so that the liquid flows back to the inner layer of the composite liquid-conducting cotton 3 and is atomized again by the heating sheet 41, thereby effectively preventing liquid from overflowing.

[0038] In an example of the present invention, at least one exhaust pipe 21 is disposed on the inner side of the side wall of the atomizing bracket 2; the composite liquid-conducting cotton 3 is partially fitted with the exhaust pipe 21 and forms a second gap 62 with the inner side of the side wall.

[0039] like Figure 4 As shown, at least one exhaust pipe 21 is arranged on the inner side of the side wall of the atomizer bracket 2, and each exhaust pipe 21 can be welded to the inner side of the side wall of the atomizer bracket 2. In order to improve the heat dissipation effect of the atomizer core, the atomizer bracket 2 can be a steel structure. The four exhaust pipes 21 are directly welded to the inner side of the side wall of the atomizer bracket 2, and the exhaust pipes 21 are symmetrical with each other.

[0040] In another example, in order to further improve the welding efficiency, the exhaust pipe 21 can be first welded to the inner side of the two groups of circular rings 22 for fixing, and then the integrated structure composed of the circular ring 22 and the exhaust pipe 21 is welded to the atomizer bracket 2. Among them, the outer diameter of the circular ring 22 is the same as the inner diameter of the atomizer bracket 2, and the circular ring 22 can fit the arc surface of the atomizer bracket 2. In addition, if the atomizer bracket 2 is not a cylinder, for example, the shape is a hollow rectangle, square, etc., at this time, the shape of the circular ring 22 can also be adapted to the size of the atomizer bracket 2 and changed.

[0041] The exhaust pipe 21 may be a solid pipe or a hollow pipe, and preferably a hollow pipe, which can further improve the exhaust effect.

[0042] like Figure 5 As shown, since the composite liquid-conducting cotton 3 is filled into the atomizing bracket 2 and each exhaust pipe 21 is respectively welded to the inner side of the side wall of the atomizing bracket 2, the composite liquid-conducting cotton 3 and the exhaust pipe 21 are only partially fitted at the contact surface, and the composite liquid-conducting cotton 3, the exhaust pipe 21 and the side wall form a second gap 62. When the atomizing core is working, the heating sheet 41 atomizes the liquid to generate gas, and the second gap 62 can effectively discharge the generated gas, further preventing the occurrence of the core sticking phenomenon.

[0043] Optionally, along the axial direction of the atomizer core, the lowest end of the exhaust pipe 21 is higher than the lowest end of the composite liquid-conducting cotton 3 , so that the composite liquid-conducting cotton 3 is located in the area below the lowest end of the exhaust pipe 21 and fits against the inner wall of the atomizer bracket 2 .

[0044] In this embodiment, the exhaust pipe 21 can extend to the lower part of the composite liquid-conducting cotton 3 along the axial direction of the atomizing core, and the lowest end of the exhaust pipe 21 must be higher than the lowest end of the composite liquid-conducting cotton 3. Since the lower end of the exhaust pipe 21 is closer to the lower end of the composite liquid-conducting cotton 3, it indicates that the length of the second gap 62 between the composite liquid-conducting cotton 3 and the atomizing bracket 2 is longer, and the second gap space formed is larger, which is easy to cause liquid to leak from the second gap 62 and cause damage to the atomizer. In order to prevent the risk of oil leakage, the distance between the lowest end of the exhaust pipe 21 and the top of the composite liquid-conducting cotton 3 can be controlled within a certain preset setting range, so that the composite liquid-conducting cotton 3 is located in the area below the lowest end of the exhaust pipe 21 and fits with the inner wall of the atomizing bracket 2 to balance the exhaust effect and the risk of oil leakage.

[0045] The preset setting range may be half the length of the composite liquid-conducting cotton 3 , so that the exhaust pipe 21 is set at the upper half of the composite liquid-conducting cotton 3 .

[0046] In one example of the present invention, the atomizer core further includes a sealing silicone 1, which is connected to the top of the atomizer bracket 2; the sealing silicone 1 is provided with a through groove 11 along the axial direction of the atomizer core at a position corresponding to the exhaust pipe 21; the exhaust pipe 21 extends along the axial direction of the atomizer core into the through groove 11 and is connected to the outside.

[0047] See also Figure 6 In this embodiment, the sealing silicone 1 can be provided with through grooves 11 along the axial direction of the atomizer core, the number of which is equal to the exhaust pipe. The opening position of the through groove 11 matches the position of the exhaust pipe 21. The exhaust pipe 21 can extend into the through groove 11 and communicate with the outside to avoid the sealing silicone 1 blocking the exhaust function of the exhaust pipe 21, thereby further improving the exhaust effect of the exhaust pipe 21 to a certain extent.

[0048] In the actual manufacturing process, since the atomizer core is usually small in size, the exhaust pipe 21 is smaller than the atomizer core, and the exhaust pipe 21 needs to pass through the through groove 11 to communicate with the outside, and the other end extends to the upper part of the composite liquid-conducting cotton 3. Therefore, the length of the exhaust pipe 21 can be increased to a certain extent, so that it can be directly processed and set in the atomizer bracket 2, reducing the processing difficulty and improving the structural stability.

[0049] In order to prevent the exhaust pipe 21 from extending too long after passing through the through groove 11 and causing damage to the suction nozzle connected to the sealing silicone 1, the pipe mouth of the exhaust pipe 21 can be flush with the through groove 11 and the size of the exhaust pipe 21 can be the same as the size of the through groove 11, so that the exhaust pipe 21 and the through groove 11 can be tightly fitted.

[0050] The liquid to be atomized may be tobacco oil or other atomizable liquids.

[0051] In an embodiment of the utility model, an atomizer core and an atomizer are provided. The atomizer core is mainly composed of an atomizer bracket, a composite liquid-conducting cotton and a heating element. A composite liquid-conducting cotton is fitted on the inner side of the side wall of the atomizer bracket, and the liquid-conducting layer of the composite liquid-conducting cotton is enclosed in the atomizer bracket to form a heating chamber, and the exhaust layer surrounds the liquid-conducting layer and covers the liquid inlet hole provided on the side wall of the atomizer bracket. When the atomizer core is used, the liquid penetrates into the exhaust layer and the liquid-conducting layer in turn through the liquid inlet hole, and the liquid is atomized by heating of the heating element. The exhaust layer is provided so that the outside air can enter the liquid tank through the exhaust layer. The overlapping arrangement of the liquid-conducting layer and the exhaust layer in the composite liquid-conducting cotton can effectively prevent the core from sticking. When it is applied to the atomizer, by optimizing the structure of the atomizer core, while maintaining the overall atomization effect of the atomizer, the service life of the atomizer can also be effectively extended.

[0052] See also Figure 7 , Figure 7 A partial structural overall schematic diagram of an atomizer in an embodiment of the utility model is shown.

[0053] An embodiment of the utility model provides an atomizer, comprising an atomizer body and an atomizer core as described in any of the above embodiments.

[0054] In an embodiment of the utility model, an atomizer is provided, which includes an atomizer core 73 of any of the above embodiments, which is installed in the atomizer body, and an oil storage cotton 74 is provided on the outer sleeve of the atomizer core 73. The atomizer core 73 and the oil storage cotton 74 are embedded in the mounting bracket 75 of the atomizer body together, and the pin 42 extending from the atomizer core 73 is connected to the power module to obtain electrical energy to perform the atomization operation. At the same time, a suction pipe structure 71 is connected to the upper end of the sealing silicone, and the suction pipe structure 71 is connected to the sealing silicone, and a suction nozzle is provided at the upper end to facilitate the user to suck. In addition, in order to improve the stability of the internal structure, the above-mentioned mounting bracket 75, the atomizer core 73 and part of the suction pipe structure 71 are surrounded by a shell 72, and the suction nozzle part of the suction pipe structure 71 passes through the shell 72 and is embedded with the shell 72 through the sealing silicone to further improve the sealing inside the shell 72 and improve the sensitivity of the atomizer core 73 to trigger.

[0055] When the user inhales through the suction tube structure 71, air is inhaled from the outside through the pipe 751 set by the mounting bracket 75, and an electrical signal is generated through an air switch or a microphone and other equipment to trigger the power supply to turn on. The pin 42 provides electrical energy to trigger the atomizer core 73 to start atomizing the liquid, effectively reducing the accumulation of atomized gas in the atomizer core 73 during the atomization process, thereby avoiding the occurrence of a core sticking phenomenon.

[0056] The outer shell 72 can be made of a light-transmitting material, and the oil-storing cotton 74 can be replaced with a liquid storage tank structure with oil-storing cotton inside. The user can directly check the liquid capacity in the liquid storage tank structure through the outer shell.
