[0018] In order to make the purpose, technical solution and advantages of the embodiments disclosed in the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present utility model.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0020] The electronic cigarette includes a battery module (not shown), an oil cup assembly (not shown) and an atomizer core assembly 100. The atomizer core assembly 100 and the oil cup assembly are combined to form an atomizer body, wherein the oil cup assembly contains smoke oil. The atomizer core assembly 100 is upright and fixed in the middle part 36 of the oil cup. The atomizer core assembly 100 can heat the atomized smoke oil to generate smoke. The oil cup assembly is located on the outer peripheral side of the atomizer core assembly 100 and is also filled with integrated cotton. The integrated cotton is a plant fiber with strong oil absorption ability. The smoke oil is locked in the integrated cotton to reduce the fluidity of the smoke oil and reduce the risk of leakage of the atomizer.

[0021] As the core component of the electronic cigarette, the atomizer core assembly 100 can heat the tobacco oil to generate aerosol for users to inhale. The quality of aerosol generation is closely related to the atomizer core assembly 100. The present disclosure provides an atomizer core assembly 100 including an internally hollow atomizer tube 3, an oil-conducting cotton 2 and a heating element 1. The atomizer tube 3 is an internally hollow cylindrical tube, and the atomizer tube 3 is divided into a top 35, a middle part 36 and a bottom 37 from top to bottom. The middle part 36 of the atomizer tube 3 is provided with a plurality of oil inlet holes 31 at intervals along the outer peripheral side of the atomizer tube 3, and a fixing part 33 is provided on the inner side wall of the atomizer tube 3 near the bottom 37. The oil-conducting cotton 2 is a hub for the transfer of tobacco oil. Under the action of capillarity, the tobacco oil on the integrated cotton is transported to the heating element 1. The heating element 1 is heated to generate heat to atomize the tobacco oil into an aerosol for users to inhale. The heating element 1 is a mesh with a preset structure. During assembly, the flat mesh heating element 1 is first laid flat on the middle part 36 of the oil-conducting cotton 2, and then a cylindrical supporting rod is placed in the middle of the heating element 1. The oil-conducting cotton 2 and the heating element 1 are wrapped together with the supporting rod and then inserted into the atomizing tube 3 from the top 35 of the atomizing tube 3 and fixed, and then the excess oil-conducting cotton 2 is cut off with pliers.

[0022] like Figure 1As shown, the atomizer core assembly 100 includes a heating element 1, oil-conducting cotton 2 and an atomizer tube 3 from the inside to the outside. The heating element 1 is wound in a cylindrical shape, and the oil-conducting cotton 2 wraps the heating element 1. When the oil-conducting cotton 2 is embedded in the atomizer tube 3, the outer side of the oil-conducting cotton 2 fits with the hole wall of the oil inlet hole 31, so that the smoke oil can quickly flow from the oil inlet hole 31 to the oil-conducting cotton 2. Pins 4 are respectively provided at both ends of the heating element 1, and the protruding ends of the two pins 4 are limited in the fixing part 33. The fixing part 33 can be a structure such as a buckle or a slot 32, which can play a good fixing role on the pin 4, preventing the heating element 1 from being deformed due to pulling the pin 4 during the assembly process, avoiding affecting the processing of subsequent processes, and thus preventing the deformation of the heating element 1 from affecting the overall quality of the electronic cigarette. Moreover, currently, the atomizer core assembly 100 on the market is generally composed of four parts: a heating element 1, an oil-conducting cotton 2, an atomizer tube 3, and an atomizer base. Based on this, a fixing portion 33 is provided in the atomizer tube 3, and there is no need to insert the atomizer base into the atomizer tube 3 to fix the pin 4, thereby achieving cost reduction on the atomizer core assembly 100, and being simple and convenient to use.

[0023] In one embodiment, see Figure 2 and Figure 3 The fixing portion 33 includes a fixing strip 331 and two positioning grooves 332. The fixing strip 331 is installed at the bottom 37 of the atomizing tube 3. The two positioning grooves 332 are spaced apart in the fixing strip 331, and each positioning groove 332 extends along the height direction of the atomizing tube 3. The opening of each positioning groove 332 is C-shaped, which is substantially the same as the shape of the pin 4, so that the pin 4 can be firmly fixed in the positioning groove 332. Furthermore, an adhesive layer (not shown) is provided in the positioning groove 332, and the adhesive layer is tightly bonded to the outer wall of the pin 4, so that the pin 4 is not easily displaced even if it is pulled by external force. Preferably, the width of the opening of the positioning groove 332 is slightly smaller than the diameter of the pin 4, so that the pin 4 will not easily fall off from the positioning groove 332.

[0024] In one embodiment, see Figure 4 The fixing portion 33 includes two buckles, which are spaced apart at the bottom 37 of the atomizer tube 3. The number of buckles is the same as the number of pins 4, and each pin 4 is buckled in the corresponding buckle. Due to the limiting effect of the buckle, the heat generating element is prevented from being deformed due to pushing the pin 4 during the assembly process, thereby avoiding affecting the processing of subsequent processes.

[0025] In one embodiment, see Figure 2 and Figure 3The bottom 37 of the atomizing tube 3 is also provided with a positioning block 34, which is arranged opposite to the fixing portion 33, and the upper surface of the positioning block 34 close to the oil-conducting cotton 2 is flush with the upper surface of the fixing portion 33 close to the oil-conducting cotton 2. That is, the upper surface of the positioning block 34 and the upper surface of the fixing portion 33 are in the same horizontal plane, so the positioning block 34 and the upper surface of the fixing portion 33 can support the bottom 37 of the oil-conducting cotton 2 at the same time, which is conducive to fixing the oil-conducting cotton 2 in the atomizing tube 3.

[0026] For further information, see Figure 1 , a slot 32 is also provided in the atomizer tube 3. The slot 32 extends from the top 35 of the atomizer tube 3 to the middle 36 of the atomizer tube 3, and the slot 32 is V-shaped or U-shaped. The oil-conducting cotton 2 is made of more than one layer of organic cotton sheets stacked and curled into a cylindrical shape. When the oil-conducting cotton 2 wrapped with the heating element 1 is assembled into the atomizer tube 3, the side ears 21 at both ends of the oil-conducting cotton 2 extend radially along the slot 32, so that the oil-conducting cotton 2 is firmly fixed in the atomizer tube 3, and it is also helpful to speed up the guide of the smoke oil in the oil cup assembly to the heating element 1, thereby accelerating the oil guide rate.

[0027] The above are only specific embodiments of the present invention, so that those skilled in the art can understand or implement the present disclosure. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
