[0002] An electronic atomizer is a product that uses heating and atomization to atomize the aerosol-generating matrix into vapor for users to inhale. The atomizer core assembly is the core component of the electronic atomizer. Currently, a known electronic atomizer uses the aerosol-generating matrix to enter the atomizer core assembly through the oil storage structure, and then heats up after the heating element of the atomizer core assembly is turned on, so that the atomizer core assembly works to atomize the aerosol-generating matrix introduced from the oil storage chamber, and then mixes it with the air flow entering from the air inlet of the electronic atomizer, and then passes through the aerosol channel for users to inhale.

[0003] In the prior art, when the heating element is a heating sheet, it is necessary to wrap the heating sheet with inner cotton and then fix it with a fixing tube. Then an oil storage structure is put on the outside to contact the inner cotton to provide an aerosol generating matrix for the inner cotton.

[0035] The present application is described in detail below with reference to the accompanying drawings and optional embodiments.

[0036] First embodiment:

[0037] Figure 7is a schematic diagram of the overall structure of the fixed tube 224 provided in the first embodiment of the present application, such as Figure 7 As shown, the fixed tube 224 includes a first end 227 and a second end 228, the first end 227 is fixed to the base 221, and the second end 228 faces in a direction away from the base 221, the hollow structure 240 includes an opening 241 and a plurality of through holes 242, the opening 241 penetrates a side wall of the fixed tube 224 along the direction from the first end 227 to the second end 228, so that a long strip-shaped gap is formed on one side of the fixed tube 224, the inner cotton 225 partially protrudes from the opening 241 to form a protrusion 243, and is arranged in contact with the oil storage structure 222, so that it is more convenient to wrap and install the inner cotton 225, and the protrusion 243 of the inner cotton 225 is clamped to fix it, and the entire fiberglass tube is inserted into it with the gap aligned.

[0038] The through hole 242 penetrates the side wall of the fixed tube 224 along a direction perpendicular to the side wall of the fixed tube 224 and is located between the first end 227 and the second end 228. The inner cotton 225 contacts the oil storage structure 222 through the opening 241 and the through hole 242. A plurality of through holes 242 are arranged around the positions of the inner cotton 225, so that other parts of the inner cotton 225 can contact the external oil storage structure 222 through the through hole 242 to absorb the aerosol generating matrix on the oil storage structure 222, thereby accelerating the speed of introducing the aerosol generating matrix and ensuring the atomization effect. Among them, the plurality of through holes 242 are runway-shaped structures, that is, a rectangular structure in the middle and semicircular structures on both sides; thus, within the same area, the area of ​​the through hole 242 of the runway-shaped structure is larger than that of the through hole 242 designed as an ellipse, so that the area corresponding to the inner cotton 225 and the through hole 242 is relatively larger, so that more inner cotton 225 can contact the oil storage structure 222, further accelerating the speed of introducing the aerosol generation matrix. Of course, the shape of the through hole 242 can also adopt other graphic designs, which are not limited here.

[0039] In addition, a plurality of through holes 242 are arranged vertically in parallel along the extension direction of the fixed tube 224, wherein the height of the through hole 242 is h1, the height of the inner cotton 225 is h2, and the height of the fixed tube 224 is H, wherein h1≦h2, and 1 / 4H≦h≦1 / 3H. That is, the height of the through hole 242 can be equal to the height of the inner cotton 225, so that on the one hand, the inner cotton 225 can completely cover the through hole 242 to avoid oil leakage, and on the other hand, the inner cotton 225 of the inner cotton 225 can be in contact with the outer oil storage structure 222 with the largest area, wherein three through holes 242 can be provided, which can ensure the maximum oil conduction while also ensuring the relatively good stability of the entire glass fiber tube. Of course, it is also possible to set only one through hole 242 in addition to the opening 241, or the specific number of through holes 242 can be designed according to the size of the electronic atomizer 20, as long as it can better guide the oil and ensure stability, it is not limited here.

[0040] Of course, it is also possible that the fixed tube 224 is not provided with the opening portion 241, and only the through hole 242 is provided around it. In this way, the protrusions 243 can be provided at the positions of the inner cotton pack 225 corresponding to the through hole 242, which protrude from the through hole 242 and contact the external oil storage structure 222; or only a through opening portion 241 is provided, and one end of the inner cotton pack 225 corresponding to the opening portion 241 protrudes from the opening portion 241 to form the protrusion 243, which contacts the oil storage structure 222. This is also possible.

[0041] like Figure 6-Figure 8 As shown, the second end 228 of the fixed tube 224 away from the base 221 is provided with an inclined portion 229, and the inclined portion 229 is arranged corresponding to the opening portion 241, and the inclined portion 229 is inclined in the direction pointing to the base 221, the inclined portion 229 includes a first oblique side 230 and a second oblique side 231, and the opening portion 241 includes a first vertical side 244 and a second vertical side 245, the first oblique side 230 is connected to the first vertical side 244, and the second oblique side 231 is connected to the second vertical side 245, and the inclined portion 229 and the opening portion 241 form a snap-fitting opening, which is convenient for inserting the inner cotton 225 into the fixed tube 224 through the snap-fitting opening.

[0042] Second embodiment:

[0043] Fig. 9 is a schematic diagram of the overall structure of the fixed tube 224 provided in the second embodiment of the present application, such as Fig. 9As shown, as the second embodiment of the present application, this embodiment is different from the first embodiment in that the multiple through holes 242 are horizontally arranged around the fixed tube 224 along the center of the fixed tube 224 in at least two circles, and the two circles of through holes 242 are staggered, so that hollowing is formed around different positions corresponding to the inner cotton 225, so that more area of ​​the inner cotton 225 can be in contact with the external oil storage structure 222 for oil conduction, and the aerosol generation matrix attached to the inner cotton 225 is more and more sufficient, avoiding core sticking and ensuring the atomization effect.

[0044] When two circles of through holes 242 are provided, the height of the two circles of through holes 242 is equal to the height of the inner cotton pack 225 , so that the contact area between the inner cotton pack 225 and the oil storage structure 222 is increased while oil leakage can be avoided.

[0045] The above content is a further detailed description of the present application in combination with specific optional implementation methods, and it cannot be determined that the specific implementation of the present application is limited to these descriptions. For ordinary technicians in the technical field to which the present application belongs, several simple deductions or substitutions can be made without departing from the concept of the present application, which should be deemed to fall within the scope of protection of the present application.
